本申请涉及电子设备技术领域，尤其涉及一种按键结构以及具有该按键结构的终端设备。The present application relates to the technical field of electronic equipment, and in particular to a key structure and a terminal device having the key structure.
背景技术Background technique
在折叠式移动终端中，通过按键来实现折叠式终端设备的开启。例如，在初始的对折状态下，折叠式移动终端的折叠屏处于对称闭合状态，同时，为了防止折叠屏在非外力作用下呈开展状态，对称后的折叠屏通过锁定结构进行锁合而保持初始状态；而在需要进行开启时，则通过按压按键对锁定结构进行解锁，以释放对称状态下的折叠屏，使其呈展开状态。In a foldable mobile terminal, the foldable terminal device is opened by pressing a button. For example, in the initial folded state, the foldable screen of the foldable mobile terminal is in a symmetrical closed state. At the same time, in order to prevent the foldable screen from being unfolded without external force, the foldable screen is locked by a locking structure to maintain the initial state; when it is necessary to open, the locking structure is unlocked by pressing a button to release the foldable screen in the symmetrical state and unfold it.
然而，按键的受压方向与锁定结构的解锁方向呈夹角设置，使得按键受牵拉而发生倾斜，无论是外观上还是使用上均影响用户的体验。However, the pressing direction of the button and the unlocking direction of the locking structure are arranged at an angle, so that the button is pulled and tilted, which affects the user experience both in appearance and in use.
发明内容Summary of the invention
本申请实施例提供一种按键结构及终端设备，可以改善按键结构在初始状态易发生倾斜的技术问题。The embodiments of the present application provide a key structure and a terminal device, which can improve the technical problem that the key structure is prone to tilt in the initial state.
为实现上述目的，本申请实施例采用如下技术方案：To achieve the above objectives, the present application embodiment adopts the following technical solutions:
第一方面，本申请提供一种按键结构，包括键帽、连接于所述键帽的按键主体以及一端固定连接于所述按键主体且另一端活动地置于外设结构的支撑件，其中，该外设结构为用于安装按键结构的结构，例如，外设结构可为电子产品的外壳或是键盘的电路板等，所述支撑件具有柔性，即，支撑件能够在按键主体按压过程中进行压缩，所述键帽和所述按键主体设于所述外设结构上，并且，所述键帽和所述按键主体在被按压后能够朝向或远离所述外设结构进行移动，所述支撑件远离所述按键主体的一端与所述外设结构相过盈配合，这里，支撑件远离按键主体的一端与外设结构之间是无连接关系，二者之间仅存在相互抵接作用力，因此，支撑件远离按键主体的一端是可与外设结构相分离的。In a first aspect, the present application provides a key structure, comprising a keycap, a key body connected to the keycap, and a support member having one end fixedly connected to the key body and the other end movably placed on an external structure, wherein the external structure is a structure for installing the key structure, for example, the external structure may be a housing of an electronic product or a circuit board of a keyboard, etc., the support member is flexible, that is, the support member can be compressed during the pressing of the key body, the keycap and the key body are arranged on the external structure, and the keycap and the key body can move toward or away from the external structure after being pressed, and the end of the support member away from the key body is interference fit with the external structure, here, there is no connection relationship between the end of the support member away from the key body and the external structure, and there is only a mutual abutment force between the two, therefore, the end of the support member away from the key body can be separated from the external structure.
本申请实施例中上述的技术方案，至少具有如下技术效果或优点：The above technical solutions in the embodiments of the present application have at least the following technical effects or advantages:
本申请实施例提供的按键结构，通过在外设结构与按键主体之间设置具有柔性的支撑件，并且，支撑件是活动连接于外设结构上的，二者之间无连接关系，仅是存在相互地抵接作用力的过盈配合，如此，支撑件能够支撑按键主体和键帽相对外设结构保持直立的平衡状态，同时，由于支撑件能够相对外设结构移动，使得支撑件能够提供按键主体在相对外设结构移动时需要自适配能力，尤其是按键主体相对外设结构发生倾斜时。The key structure provided in the embodiment of the present application is achieved by providing a flexible support member between the peripheral structure and the key body, and the support member is movably connected to the peripheral structure. There is no connection relationship between the two, and there is only an interference fit of mutual abutting forces. In this way, the support member can support the key body and the keycap to maintain an upright balanced state relative to the peripheral structure. At the same time, since the support member can move relative to the external structure, the support member can provide the key body with the self-adaptation capability required when it moves relative to the external structure, especially when the key body is tilted relative to the external structure.
在第一方面的一些实施例中，所述按键主体包括按压部以及由所述按压部向外延伸的延伸部，所述延伸部朝向或远离所述外设结构进行按压移动，所述支撑件固定连接于所述按压部。In some embodiments of the first aspect, the button body includes a pressing portion and an extending portion extending outward from the pressing portion, the extending portion is pressed and moved toward or away from the peripheral structure, and the support member is fixedly connected to the pressing portion.
按压部用于供使用者进行按压，延伸部用于与外设力结构相适配连接，并且，延伸部是朝向于外设结构的，因此，为了实现按键结构整体处于直立的平衡状态，支撑件对按压部进行支撑，使得按压部与外设结构的表面之间存在活动余量。The pressing portion is used for the user to press, and the extending portion is used for adapting and connecting with the external force structure, and the extending portion is oriented toward the external structure. Therefore, in order to achieve an upright and balanced state of the entire key structure, the support member supports the pressing portion so that there is a movable margin between the pressing portion and the surface of the external structure.
在第一方面的一些实施例中，所述按压部上设有定位结构，所述支撑件上设有与所述定位结构相适配的定位配合结构。In some embodiments of the first aspect, a positioning structure is provided on the pressing portion, and a positioning matching structure matched with the positioning structure is provided on the supporting member.
定位结构可以为定位柱、定位凸起、定位凸筋等，定位适配结构是与定位结构相适配的结构，定位适配结构可为定位孔、定位槽等，如此，通过定位结构和定位适配结构相配合，以提升支撑件与按压部的连接稳定性。The positioning structure can be a positioning column, a positioning protrusion, a positioning rib, etc. The positioning adapter structure is a structure that is compatible with the positioning structure. The positioning adapter structure can be a positioning hole, a positioning groove, etc. In this way, the positioning structure and the positioning adapter structure cooperate to improve the connection stability between the support member and the pressing part.
在第一方面的一些实施例中，所述定位结构包括定位孔，所述定位配合结构包括定位柱，所述定位柱穿设于所述定位孔内。In some embodiments of the first aspect, the positioning structure includes a positioning hole, and the positioning matching structure includes a positioning column, and the positioning column is inserted into the positioning hole.
利用定位柱伸入定位孔内，以提升支撑件与按压部之间的连接稳定性。The positioning column is extended into the positioning hole to improve the connection stability between the support member and the pressing portion.
在第一方面的一些实施例中，所述定位柱与所述支撑件一体成型，所述定位孔包括相连通的第一孔段以及第二孔段，所述第一孔段的内径大于所述第二孔段的内径，并且，所述第一孔段远离于所述支撑件。In some embodiments of the first aspect, the positioning column is integrally formed with the support member, the positioning hole includes a first hole segment and a second hole segment that are connected, the inner diameter of the first hole segment is larger than the inner diameter of the second hole segment, and the first hole segment is far away from the support member.
调整第一孔段的内径和第二孔段的内径的大小，形成差异性设置，定位孔为台阶孔，同时，定位柱与支撑件采用相同的材料制得，定位柱可通过注塑等工艺形成台阶孔内，如此，支撑件不易从按压部上分离，能够进一步地支撑件在按压部上的连接稳定性。The sizes of the inner diameters of the first hole segment and the second hole segment are adjusted to form a differential setting. The positioning hole is a stepped hole. At the same time, the positioning column and the support member are made of the same material. The positioning column can be formed in the stepped hole by injection molding and other processes. In this way, the support member is not easily separated from the pressing portion, which can further enhance the connection stability of the support member on the pressing portion.
在第一方面的一些实施例中，所述第一孔段的内径沿按压方向逐渐减小。In some embodiments of the first aspect, an inner diameter of the first hole segment gradually decreases along the pressing direction.
可以理解地，第一孔段的孔壁呈锥状，更加便于加工，同时，定位柱在定位孔内的限位受力最小，也便于定位柱从定位孔内脱出。It can be understood that the hole wall of the first hole section is tapered, which is more convenient for processing. At the same time, the limiting force of the positioning column in the positioning hole is minimal, which also makes it easier for the positioning column to escape from the positioning hole.
在第一方面的一些实施例中，所述支撑件包括连接于所述按键主体的连接部以及由所述连接部向外延伸的支撑部，所述支撑部背离所述连接部的一端与所述外设结构相过盈配合。In some embodiments of the first aspect, the support member includes a connecting portion connected to the key body and a supporting portion extending outward from the connecting portion, and an end of the supporting portion facing away from the connecting portion is interference fit with the peripheral structure.
连接部用于与按键主体相连接，支撑部则是用于与外设结构相接触且与其进行过盈配合，如此，连接部可为板状或块状结构，与按键主体相贴合，支撑部同样可为板状或块状结构，并且，支撑部呈扩口结构，能够进一步提升对按键主体的支撑，同时，支撑部是直接与外设结构相抵接而实现过盈配合的。The connecting part is used to connect with the key body, and the supporting part is used to contact with the external structure and perform interference fit therewith. In this way, the connecting part can be a plate-shaped or block-shaped structure, which fits with the key body. The supporting part can also be a plate-shaped or block-shaped structure, and the supporting part has a flared structure, which can further enhance the support for the key body. At the same time, the supporting part directly abuts against the external structure to achieve interference fit.
在第一方面的一些实施例中，所述支撑件还包括抵接部，所述抵接部设于所述支撑部远离所述连接部的一端。In some embodiments of the first aspect, the support member further includes an abutment portion, and the abutment portion is provided at an end of the support portion away from the connection portion.
可以理解地，本实施例中，支撑部是与外设结构相间接连接，即，支撑部通过抵接部与外设结构相抵接，如此，抵接部可增加支撑部与外设结构之间的接触面积。It can be understood that in this embodiment, the support portion is indirectly connected to the external structure, that is, the support portion abuts against the external structure through the abutment portion, so that the abutment portion can increase the contact area between the support portion and the external structure.
在第一方面的一些实施例中，所述按键主体通过所述支撑件密封连接于所述外设结构。In some embodiments of the first aspect, the button body is sealed and connected to the peripheral structure through the support member.
密封连接是指按键主体与外设结构之间间隙被支撑件所填补，能够起到一定的防水防尘的功能。例如，在按压方向上，支撑件能够对按键主体在外设结构上的投影范围内的区域进行防水防尘。Sealed connection means that the gap between the key body and the peripheral structure is filled by the support, which can play a certain role in waterproofing and dustproofing. For example, in the pressing direction, the support can waterproof and dustproof the area within the projection range of the key body on the peripheral structure.
在第一方面的一些实施例中，所述按键结构还包括粘接层，所述键帽通过所述粘接层连接于所述按键主体。In some embodiments of the first aspect, the key structure further includes an adhesive layer, and the key cap is connected to the key body through the adhesive layer.
可以理解地，粘接工艺的连接方式更为简单和便捷，尤其适合在按压方向上，按键主体的投影位于键帽内的情形。It can be understood that the connection method of the bonding process is simpler and more convenient, and is particularly suitable for the situation where the projection of the key body is located inside the key cap in the pressing direction.
第二方面，本申请实施例提供一种终端设备，包括：In a second aspect, an embodiment of the present application provides a terminal device, including:
壳体；case;
折叠屏，所述折叠屏连接于所述壳体，并且，所述折叠屏能够翻折或展开；A folding screen, the folding screen is connected to the housing, and the folding screen can be folded or unfolded;
锁定机构，所述锁定机构设于所述壳体内，所述锁定机构包括锁定件，所述锁定件用于锁定处于翻折状态下的所述折叠屏；A locking mechanism, the locking mechanism is arranged in the housing, the locking mechanism comprises a locking member, and the locking member is used to lock the folding screen in a folded state;
上述所述的按键结构，所述按键结构的按键主体穿设于所述壳体且与所述锁定件相适配，所述按键结构的按键主体的按压方向与所述锁定件的锁定方向呈夹角设置，所述按键结构沿所述按压方向移动以带动所述锁定件背离所述锁定方向移动，所述锁定件完成解锁动作；在所述锁定件处于锁定状态下，所述按键结构的支撑件用于支撑所述按键主体，以使所述按键主体平衡地维持于所述壳体上；The key structure described above, the key body of the key structure is inserted into the housing and matched with the locking member, the pressing direction of the key body of the key structure is set at an angle with the locking direction of the locking member, the key structure moves along the pressing direction to drive the locking member to move away from the locking direction, and the locking member completes the unlocking action; when the locking member is in the locked state, the support member of the key structure is used to support the key body, so that the key body is maintained on the housing in a balanced manner;
其中，所述按键主体被配置为沿按压方向移动时，所述锁定件沿背离所述锁定方向移动，以使所述折叠屏解锁呈展开状态。Wherein, when the button body is configured to move along the pressing direction, the locking piece moves away from the locking direction so that the folding screen is unlocked and in an unfolded state.
本申请实施例中上述的技术方案，至少具有如下技术效果或优点：The above technical solutions in the embodiments of the present application have at least the following technical effects or advantages:
本申请实施例提供的终端设备，其折叠屏在翻折状态，可通过锁定机构的锁定件进行锁定并维持处于折叠的状态，当折叠屏需要展开时，按压按键结构，按键主体带动锁定件背离锁定方向移动，以实现折叠屏解锁，如此，折叠屏呈展开状态。由于锁定件的锁定方向与按键主体的按压方向呈夹角，按键主体因牵拉作用而出现倾斜，此时，支撑件则可维持按键主体处于平衡状态，降低其在非按压状态下发生倾斜的概率。The terminal device provided in the embodiment of the present application has a folding screen that can be locked and maintained in a folded state by a locking member of a locking mechanism when the folding screen is in a folded state. When the folding screen needs to be unfolded, the key structure is pressed, and the key body drives the locking member to move away from the locking direction to unlock the folding screen. In this way, the folding screen is in an unfolded state. Since the locking direction of the locking member and the pressing direction of the key body form an angle, the key body tilts due to the pulling effect. At this time, the support member can maintain the key body in a balanced state, reducing the probability of it tilting in a non-pressed state.
在第二方面的一些实施例中，所述锁定件上开设有供所述按键主体穿设的通孔结构，所述通孔结构的内壁上设有拨动杆，所述按键主体上开设导向槽，在所述按键主体沿所述按压方向移动时，所述拨动杆于所述导向槽内滑动，以带动所述锁定件背离所述锁定方向移动。In some embodiments of the second aspect, a through hole structure is provided on the locking piece for the key body to pass through, a toggle rod is provided on the inner wall of the through hole structure, and a guide groove is provided on the key body. When the key body moves along the pressing direction, the toggle rod slides in the guide groove to drive the locking piece to move away from the locking direction.
按键主体通过通孔结构与锁定件在位置上形成干涉，按键主体在受压沿按压方向移动时，拨动杆则在导向槽内滑动，以使带动拨动杆和锁定件沿背离锁定方向进行移动，以完成对折叠屏的解锁。The button body interferes with the locking piece in position through the through-hole structure. When the button body moves in the pressing direction under pressure, the toggle rod slides in the guide groove, so as to drive the toggle rod and the locking piece to move in the direction away from the locking direction, thereby completing the unlocking of the folding screen.
在第二方面的一些实施例中，所述锁定机构还包括复位件，所述复位件的一端抵接于所述壳体的内壁且另一端抵接于所述锁定件，以使所述锁定件沿所述锁定方向凸伸。In some embodiments of the second aspect, the locking mechanism further includes a reset member, one end of which abuts against an inner wall of the shell and the other end of which abuts against the locking member, so that the locking member protrudes along the locking direction.
复位件始终处于压缩状态，即，沿锁定方向对锁定件持续施加推动力，以使锁定件始终处于锁定状态。The reset member is always in a compressed state, that is, a pushing force is continuously applied to the locking member along the locking direction so that the locking member is always in a locked state.

为了使本申请的目的、技术方案及优点更加清楚明白，以下结合附图及实施例，对本申请进行进一步详细说明。In order to make the objectives, technical solutions and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments.
传统的按键是通过硅胶支撑结构提供其在X方向上，即，按压方向上对键帽进行支撑，为了进一步地提升键帽的支撑稳定性，在键帽和固定板之间还设置有剪刀脚结构，剪刀脚结构的一端铰接于固定板上，且另一端铰接于键帽上，利用剪刀脚结构能够在Z方向上进行开合，来对键帽提供更大范围的支撑，以维持键帽的平衡。Traditional keys are supported by a silicone support structure in the X direction, that is, in the pressing direction, to support the keycap. In order to further improve the supporting stability of the keycap, a scissor foot structure is provided between the keycap and the fixed plate. One end of the scissor foot structure is hinged to the fixed plate, and the other end is hinged to the keycap. The scissor foot structure can be opened and closed in the Z direction to provide a wider range of support for the keycap to maintain the balance of the keycap.
然而，在一些锁定或解锁场景下，按键还会受到牵拉作用力，由于剪刀脚结构的两端分别与键帽和固定板之间呈铰接连接，使得剪刀脚结构易受力发生偏位，从而导致键帽在初始状态下也发生倾斜。However, in some locking or unlocking scenarios, the keys will still be subjected to pulling force. Since the two ends of the scissor foot structure are respectively hingedly connected to the keycap and the fixed plate, the scissor foot structure is easily displaced by force, causing the keycap to tilt in the initial state.
有鉴于此，本申请实施例提供一种按键结构，在按键主体和外设结构之间设置一支撑件，该支撑件具有柔性，其一端固定连接于按键主体且另一端活动地置于外设结构，并且，支撑件远离按键主体的一端与外设结构相过盈配合。如此，在键帽和按键主体朝向或远离外设结构进行按压移动时，支撑件均能够提供按键主体所需的支撑平衡力，尤其是按键主体相对外设结构发生倾斜时。In view of this, the embodiment of the present application provides a key structure, wherein a support member is arranged between the key body and the peripheral structure, the support member is flexible, one end of which is fixedly connected to the key body and the other end is movably placed in the peripheral structure, and the end of the support member away from the key body is in interference fit with the peripheral structure. In this way, when the key cap and the key body are pressed and moved toward or away from the peripheral structure, the support member can provide the supporting balance force required by the key body, especially when the key body is tilted relative to the peripheral structure.
本申请实施例提供的终端设备属于可折叠电子设备，即能够实现折叠和展开的一类电子设备。例如，终端设备可以为手机、平板电脑、膝上型电脑(Laptop)、笔记本电脑(Notebook PC)、个人数码助理(Personal Digital Assistant，PDA)、可穿戴设备(例如手表)、车载设备、增强现实(Augmented Reality，AR)/虚拟现实(Virtual Reality，VR)设备、销售终端(POS，Point of sales terminal)、行车记录仪、对讲机、摄像机、显示器等，但不限于此。The terminal device provided in the embodiment of the present application belongs to a foldable electronic device, that is, a type of electronic device that can be folded and unfolded. For example, the terminal device can be a mobile phone, a tablet computer, a laptop computer (Laptop), a notebook computer (Notebook PC), a personal digital assistant (Personal Digital Assistant, PDA), a wearable device (such as a watch), a vehicle-mounted device, an augmented reality (Augmented Reality, AR)/virtual reality (Virtual Reality, VR) device, a sales terminal (POS, Point of sales terminal), a driving recorder, a walkie-talkie, a camera, a display, etc., but not limited thereto.

也同时参考图3至图5，本申请实施例提供一种终端设备1000，包括壳体100、折叠屏200、锁定机构300和按键结构400。Also referring to FIGS. 3 to 5 , an embodiment of the present application provides a terminal device 1000 , including a housing 100 , a folding screen 200 , a locking mechanism 300 and a button structure 400 .
壳体100为终端设备1000中无显示功能结构部分。壳体100起到承载折叠屏200的作用。The housing 100 is a non-display functional structural part of the terminal device 1000. The housing 100 serves to carry the folding screen 200.
折叠屏200连接于壳体100，并且，折叠屏200能够翻折或展开。The folding screen 200 is connected to the housing 100 , and the folding screen 200 can be folded or unfolded.
折叠屏200为柔性显示屏，具有可折叠功能，因此，该终端设备1000存在两种使用状态，一是折叠屏200处于折叠状态，用户使用折叠屏200的部分显示区域；二是展开状态，用户可使用过折叠屏200的全部显示区域。在折叠屏200折叠和展开过程中，壳体100起到相应的承载作用，因此，折叠屏200与壳体100连接关系包括但不限于是插接、卡接、螺纹连接以及通过安装结构等间接连接等。The folding screen 200 is a flexible display screen with a foldable function. Therefore, the terminal device 1000 has two usage states: one is that the folding screen 200 is in a folded state, and the user uses part of the display area of the folding screen 200; the other is an unfolded state, and the user can use the entire display area of the folding screen 200. During the folding and unfolding process of the folding screen 200, the housing 100 plays a corresponding bearing role. Therefore, the connection relationship between the folding screen 200 and the housing 100 includes but is not limited to plug-in, snap-on, threaded connection, and indirect connection through a mounting structure.
锁定机构300用于将折叠屏200进行锁定，保持折叠屏200处于折叠状态，以防止折叠屏200展开。The locking mechanism 300 is used to lock the folding screen 200 and keep the folding screen 200 in a folded state to prevent the folding screen 200 from unfolding.
具体地，锁定机构300设于壳体100内，锁定机构300包括锁定件301，锁定件301用于锁定处于翻折状态下的折叠屏200。Specifically, the locking mechanism 300 is disposed in the housing 100 , and the locking mechanism 300 includes a locking member 301 , and the locking member 301 is used to lock the folding screen 200 in a folded state.
锁定件301属于锁定机构300的一部分，主要是与折叠屏200的折叠部直接或间接相互作用，而防止折叠屏200在外力的作用下展开。The locking member 301 is a part of the locking mechanism 300 , and mainly interacts directly or indirectly with the folding portion of the folding screen 200 to prevent the folding screen 200 from unfolding under the action of external force.
可以理解地，锁定件301能够相对壳体100移动，在移动过程中对折叠屏200进行解锁或锁定，这样，将锁定件301朝向折叠屏200移动的且实现与折叠屏200相作用而满足锁定的方向成为锁定方向Y，例如，锁定方向Y可是与折叠屏200的展开方向相重合，或者，锁定方向Y与折叠屏200的展开方向相垂直。以及，折叠屏200上也应设有与锁定件301相适配的结构，以与锁定件301相互作用。因此，折叠屏200上与锁定件301相适配的结构可为孔结构或卡扣结构。It can be understood that the locking member 301 can move relative to the housing 100, and unlock or lock the folding screen 200 during the movement. In this way, the direction in which the locking member 301 moves toward the folding screen 200 and interacts with the folding screen 200 to meet the locking becomes the locking direction Y. For example, the locking direction Y may coincide with the unfolding direction of the folding screen 200, or the locking direction Y may be perpendicular to the unfolding direction of the folding screen 200. In addition, the folding screen 200 should also be provided with a structure that matches the locking member 301 to interact with the locking member 301. Therefore, the structure on the folding screen 200 that matches the locking member 301 may be a hole structure or a buckle structure.
按键结构400用于对锁定机构300的锁定件301进行解锁。The button structure 400 is used to unlock the locking member 301 of the locking mechanism 300 .
具体地，按键结构400包括键帽41、按键主体42以及支撑件43。其中，键帽41设于按键主体42背离壳体100的一侧，支撑件43的一端固定连接于按键主体42且另一端活动地置于壳体100上，以及，支撑件43的端部与壳体100相抵接，即，二者之间存在相互作用力，可以理解地，支撑件43的初始状态是处于受压的。这里，支撑件43与壳体100之间是发生相对移动的。以及，支撑件43是用于将按键主体42支撑在壳体100上的，同时，支撑件43具有柔性，在用户对按键结构400进行按压时，支撑件43可进行压缩，而在外力被解除时，支撑件43则将按键主体42进行复位，因此，按键结构400的按压方向即是支撑件43受压的方向。Specifically, the key structure 400 includes a key cap 41, a key body 42 and a support member 43. The key cap 41 is arranged on the side of the key body 42 away from the housing 100, one end of the support member 43 is fixedly connected to the key body 42 and the other end is movably placed on the housing 100, and the end of the support member 43 is in contact with the housing 100, that is, there is an interaction force between the two. It can be understood that the initial state of the support member 43 is under pressure. Here, the support member 43 and the housing 100 move relative to each other. And the support member 43 is used to support the key body 42 on the housing 100. At the same time, the support member 43 is flexible. When the user presses the key structure 400, the support member 43 can be compressed, and when the external force is released, the support member 43 resets the key body 42. Therefore, the pressing direction of the key structure 400 is the direction in which the support member 43 is compressed.
按键结构400的按键主体42穿设于壳体100且与锁定件301相适配，按键结构400的按键主体42的按压方向X与锁定件301的锁定方向Y呈夹角，因而，锁定件301对按键主体42有牵拉作用，而造成按键主体42发生倾斜。The key body 42 of the key structure 400 is inserted into the shell 100 and matched with the locking member 301. The pressing direction X of the key body 42 of the key structure 400 and the locking direction Y of the locking member 301 form an angle. Therefore, the locking member 301 has a pulling effect on the key body 42, causing the key body 42 to tilt.
按键结构400沿按压方向X移动以带动锁定件301背离锁定方向Y移动，锁定件301完成解锁动作；在锁定件301处于锁定状态下，支撑件43用于支撑按键主体42，以使按键主体42平衡地置于壳体100上。The key structure 400 moves along the pressing direction X to drive the locking member 301 to move away from the locking direction Y, and the locking member 301 completes the unlocking action; when the locking member 301 is in the locked state, the support member 43 is used to support the key body 42 so that the key body 42 is placed on the shell 100 in a balanced manner.
其中，按键主体42被配置为沿按压方向X移动时，锁定件301沿背离锁定方向Y移动，以使折叠屏200解锁呈展开状态。这里，也说明了按键主体42会发生倾斜的原因。The button body 42 is configured to move along the pressing direction X, and the locking member 301 moves away from the locking direction Y, so that the folding screen 200 is unlocked and unfolded. Here, the reason why the button body 42 may tilt is also explained.
本申请实施例中上述的技术方案，至少具有如下技术效果或优点：The above technical solutions in the embodiments of the present application have at least the following technical effects or advantages:
本申请实施例提供的终端设备1000，其折叠屏200在翻折状态，可通过锁定机构300的锁定件301进行锁定并维持处于折叠的状态，当折叠屏200需要展开时，按压按键结构400，按键主体42带动锁定件301背离锁定方向Y移动，以实现折叠屏200解锁，如此，折叠屏200呈展开状态。由于锁定件301的锁定方向Y与按键主体42的按压方向X呈夹角，按键主体42因牵拉作用而出现倾斜，此时，支撑件43则可维持按键主体42处于平衡状态，降低其在非按压状态下发生倾斜的概率。The terminal device 1000 provided in the embodiment of the present application has a folding screen 200 that can be locked and maintained in a folded state by the locking member 301 of the locking mechanism 300 when in a folded state. When the folding screen 200 needs to be unfolded, the key structure 400 is pressed, and the key body 42 drives the locking member 301 to move away from the locking direction Y to unlock the folding screen 200. In this way, the folding screen 200 is in an unfolded state. Since the locking direction Y of the locking member 301 and the pressing direction X of the key body 42 form an angle, the key body 42 tilts due to the pulling effect. At this time, the support member 43 can maintain the key body 42 in a balanced state, reducing the probability of it tilting in a non-pressed state.
请参考3至图5、图7，锁定件301上开设有供按键主体42穿设的通孔结构302，通孔结构302的内壁上设有拨动杆303，按键主体42上开设导向槽422a，在按键主体42沿按压方向X移动时，拨动杆303于导向槽422a内滑动，以带动锁定件301背离锁定方向Y移动。Please refer to Figures 3 to 5 and 7. A through hole structure 302 is provided on the locking member 301 for the key body 42 to pass through. A toggle rod 303 is provided on the inner wall of the through hole structure 302. A guide groove 422a is provided on the key body 42. When the key body 42 moves along the pressing direction X, the toggle rod 303 slides in the guide groove 422a to drive the locking member 301 to move away from the locking direction Y.
可以理解地，按键主体42通过通孔结构302与锁定件301在位置上形成干涉，按键主体42在受压沿按压方向X移动时，拨动杆303则在导向槽422a内滑动，以使带动拨动杆303和锁定件301沿背离锁定方向Y进行移动，以完成对折叠屏200的解锁。It can be understood that the button body 42 forms an interference with the locking piece 301 in position through the through hole structure 302. When the button body 42 moves along the pressing direction X under pressure, the toggle rod 303 slides in the guide groove 422a, so as to drive the toggle rod 303 and the locking piece 301 to move in the direction away from the locking direction Y, so as to complete the unlocking of the folding screen 200.
具体地，按键主体42的按压方向X与锁定件301的锁定方向Y相垂直，那么，导向槽422a则具有与斜面，在按键主体42相对壳体100进行下压时，按键主体42推动拨动杆303在导向槽422a的斜面上滑动，使得锁定件301沿背离锁定方向Y移动，此时，锁定件301缩回的状态，即，锁定件301解除对折叠屏200的锁定，折叠屏200可进行展开。Specifically, the pressing direction X of the button body 42 is perpendicular to the locking direction Y of the locking piece 301, so the guide groove 422a has an inclined surface. When the button body 42 is pressed down relative to the shell 100, the button body 42 pushes the toggle rod 303 to slide on the inclined surface of the guide groove 422a, so that the locking piece 301 moves away from the locking direction Y. At this time, the locking piece 301 is in a retracted state, that is, the locking piece 301 releases the lock on the folding screen 200, and the folding screen 200 can be unfolded.
可选地，为了进一步地提升按键主体42与锁定件301联动顺畅程度，拨动杆303呈圆柱状，圆柱状的拨动杆303与导向槽422a的槽壁之间为线接触，即，二者之间的接触面积更小，拨动件在导向槽422a内滑动更加顺畅。Optionally, in order to further improve the smoothness of the linkage between the button body 42 and the locking member 301, the toggle rod 303 is cylindrical, and there is a line contact between the cylindrical toggle rod 303 and the groove wall of the guide groove 422a, that is, the contact area between the two is smaller, and the toggle member slides more smoothly in the guide groove 422a.
请参考图3至图5，锁定机构300还包括复位件304，复位件304的一端抵接于壳体100的内壁且另一端抵接于锁定件301，以使锁定件301沿锁定方向Y凸伸。3 to 5 , the locking mechanism 300 further includes a reset member 304 , one end of which abuts against the inner wall of the housing 100 and the other end of which abuts against the locking member 301 , so that the locking member 301 protrudes along the locking direction Y.
复位件304可复位弹簧，或者，也可以是具有发生形变的弹性体，例如，弹性块或弹性柱等，复位件304的作用是将锁定件301进行复位，即，复位件304始终处于压缩状态，其沿锁定方向Y对锁定件301持续施加推动力，以使锁定件301始终处于锁定状态。The reset member 304 can be a reset spring, or it can also be an elastic body that can be deformed, such as an elastic block or an elastic column. The function of the reset member 304 is to reset the locking member 301, that is, the reset member 304 is always in a compressed state, and it continuously applies a pushing force to the locking member 301 along the locking direction Y so that the locking member 301 is always in a locked state.
正是由于复位件304的持续作用力，对与锁定件301相干涉的按键主体42受到与按压方向X呈夹角的作用力，使得按键主体42会相对壳体100发生倾斜，并且，按键主体42的倾斜方向与锁定件301的锁定方向Y相背离。如此，则需要支撑件43对按键主体42进行支撑，以维持按键主体42呈直立状态或呈近似的直立状态，以提升按键主体42在再次受压过程中相对壳体100移动的顺畅度。It is due to the continuous force of the reset member 304 that the key body 42 interfering with the locking member 301 is subjected to a force at an angle to the pressing direction X, so that the key body 42 is tilted relative to the housing 100, and the tilting direction of the key body 42 is opposite to the locking direction Y of the locking member 301. In this case, the support member 43 is required to support the key body 42 to maintain the key body 42 in an upright state or a nearly upright state, so as to improve the smoothness of the key body 42 moving relative to the housing 100 during the next compression process.
请参考图6和图7，图6示出了本申请一些实施例提供的按键结构400的爆炸图；图7示出了本申请一些实施例提供的按键结构400的按键主体42的剖面图。Please refer to Figures 6 and 7. Figure 6 shows an exploded view of a key structure 400 provided in some embodiments of the present application; Figure 7 shows a cross-sectional view of a key body 42 of a key structure 400 provided in some embodiments of the present application.
具体地，按键结构400包括键帽41、连接于键帽41的按键主体42以及一端固定连接于按键主体42且另一端活动地置于外设结构101的支撑件43。Specifically, the key structure 400 includes a key cap 41 , a key body 42 connected to the key cap 41 , and a support member 43 , one end of which is fixedly connected to the key body 42 and the other end of which is movably disposed on the peripheral structure 101 .
其中，该外设结构101为用于安装按键结构400的结构，例如，外设结构101可为电子产品的外壳或是键盘的电路板等。The peripheral structure 101 is a structure for installing the key structure 400 . For example, the peripheral structure 101 may be a housing of an electronic product or a circuit board of a keyboard.
支撑件43具有柔性，即，支撑件43能够在按键主体42按压过程中进行压缩，键帽41和按键主体42设于外设结构101上，并且，键帽41和按键主体42能够朝向或远离外设结构101进行按压移动，支撑件43远离按键主体42的一端与外设结构101相过盈配合，这里，支撑件43远离按键主体42的一端与外设结构101之间是无连接关系，二者之间仅存在相互抵接作用力，因此，支撑件43远离按键主体42的一端是可与外设结构101相分离的。The support member 43 is flexible, that is, the support member 43 can be compressed during the pressing process of the key body 42. The keycap 41 and the key body 42 are arranged on the external structure 101, and the keycap 41 and the key body 42 can be pressed and moved toward or away from the external structure 101. The end of the support member 43 away from the key body 42 is interference fit with the external structure 101. Here, there is no connection between the end of the support member 43 away from the key body 42 and the external structure 101, and there is only a mutual abutment force between the two. Therefore, the end of the support member 43 away from the key body 42 can be separated from the external structure 101.
支撑件43的材质包括但不限是硅胶、橡胶、塑料等。The material of the support member 43 includes but is not limited to silicone, rubber, plastic, etc.
本申请实施例提供的按键结构400，通过在外设结构101与按键主体42之间设置具有柔性的支撑件43，并且，支撑件43是活动连接于外设结构101上的，二者之间无连接关系，仅是存在相互地抵接作用力的过盈配合，如此，支撑件43能够支撑按键主体42和键帽41相对外设结构101保持直立的平衡状态，同时，由于支撑件43能够相对外设结构101移动，使得支撑件43能够提供按键主体42在相对外设结构101移动时需要自适配能力，尤其是按键主体42相对外设结构101发生倾斜时。The key structure 400 provided in the embodiment of the present application is provided with a flexible support member 43 between the peripheral structure 101 and the key body 42, and the support member 43 is movably connected to the peripheral structure 101. There is no connection relationship between the two, and there is only an interference fit with each other's abutting force. In this way, the support member 43 can support the key body 42 and the keycap 41 to maintain an upright balanced state relative to the external structure 101. At the same time, since the support member 43 can move relative to the external structure 101, the support member 43 can provide the key body 42 with the self-adaptation capability required when it moves relative to the external structure 101, especially when the key body 42 is tilted relative to the external structure 101.
请参考图6，在一些实施例中，按键主体42包括按压部421以及由按压部421向外延伸的延伸部422，延伸部422朝向或远离外设结构101进行按压移动，支撑件43固定连接于按压部421。Please refer to Figure 6. In some embodiments, the button body 42 includes a pressing portion 421 and an extending portion 422 extending outward from the pressing portion 421. The extending portion 422 is pressed toward or away from the external structure 101, and the support member 43 is fixedly connected to the pressing portion 421.
按压部421用于供使用者进行按压，延伸部422用于与外设力结构相适配连接，并且，延伸部422是朝向于外设结构101的，因此，为了实现按键结构400整体处于直立的平衡状态，支撑件43对按压部421进行支撑，使得按压部421与外设结构101的表面之间存在活动余量。The pressing portion 421 is used for the user to press, and the extending portion 422 is used for adapting and connecting with the external force structure, and the extending portion 422 is facing the external structure 101. Therefore, in order to achieve that the button structure 400 is in an upright balanced state as a whole, the support member 43 supports the pressing portion 421 so that there is a movable margin between the pressing portion 421 and the surface of the external structure 101.
这里，按压部421的轮廓外形不做限定。在按压方向X上，按压部421在外设结构101上的投影可为圆形、方形或跑道形等，延伸部422则类似于柱状结构或杆状结构，延伸部422是设于按压部421朝向于外设结构101一侧的，用于与外设结构101相适配，例如，在按键主体42按压过程中，按压部421带动延伸部422一起朝向外设结构101移动，此时，延伸部422与外设结构101相干涉，以完成相应的联动动作，例如，利用延伸部422触发锁定或解锁，或者，利用延伸部422触发指令输入等。Here, the contour of the pressing portion 421 is not limited. In the pressing direction X, the projection of the pressing portion 421 on the peripheral structure 101 can be circular, square or track-shaped, etc., and the extension portion 422 is similar to a columnar structure or a rod-shaped structure. The extension portion 422 is arranged on the side of the pressing portion 421 facing the peripheral structure 101, and is used to adapt to the peripheral structure 101. For example, during the pressing process of the key body 42, the pressing portion 421 drives the extension portion 422 to move toward the peripheral structure 101. At this time, the extension portion 422 interferes with the peripheral structure 101 to complete the corresponding linkage action, for example, using the extension portion 422 to trigger locking or unlocking, or using the extension portion 422 to trigger command input, etc.
支撑件43的一端则是固定在按压部421上，另一端与外设结构101相抵接，以对非施压状态下的按键主体42进行支撑。One end of the support member 43 is fixed on the pressing portion 421 , and the other end is in contact with the external structure 101 to support the key body 42 in a non-pressurized state.
支撑件43与按压部421的连接方式包括但不限于是粘接连接、插接、卡接、螺纹连接以及一体成型等。也即，支撑件43与按压部421相连接的端侧不与按压部421发生相对移动。The connection between the support member 43 and the pressing portion 421 includes, but is not limited to, bonding, plugging, clamping, threading, and integral molding, etc. That is, the end side of the support member 43 connected to the pressing portion 421 does not move relative to the pressing portion 421 .
同时，支撑件43的数量也不限定，可以是一个、两个或的多个，用于对按压部421提供相应的平衡支撑力。Meanwhile, the number of the supporting members 43 is not limited, and may be one, two, or more, for providing a corresponding balanced supporting force to the pressing portion 421 .
请参考图6，在一些实施例中，按压部421上设有定位结构44，支撑件43上设有与定位结构44相适配的定位配合结构45。Please refer to FIG. 6 . In some embodiments, a positioning structure 44 is provided on the pressing portion 421 , and a positioning matching structure 45 matched with the positioning structure 44 is provided on the supporting member 43 .
定位结构44可以为定位柱、定位凸起、定位凸筋等，定位适配结构是与定位结构44相适配的结构，定位适配结构可为定位孔、定位槽等，如此，通过定位结构44和定位适配结构相配合，以提升支撑件43与按压部421的连接稳定性。The positioning structure 44 can be a positioning column, a positioning protrusion, a positioning rib, etc. The positioning adapter structure is a structure that is compatible with the positioning structure 44. The positioning adapter structure can be a positioning hole, a positioning groove, etc. In this way, the positioning structure 44 and the positioning adapter structure cooperate to improve the connection stability between the support member 43 and the pressing portion 421.
可以理解地，定位结构44和定位配合结构45可提升支撑件43在按压部421上的位置精度。It can be understood that the positioning structure 44 and the positioning matching structure 45 can improve the position accuracy of the support member 43 on the pressing portion 421 .
示例地，定位结构44为开设于按压部421上的通孔，定位适配结构为设于支撑件43上的凸柱，凸柱与通孔相适配，从而确定支撑件43在按压部421上的设置位置。For example, the positioning structure 44 is a through hole opened on the pressing portion 421 , and the positioning adaptation structure is a convex column provided on the support member 43 , which is adapted to the through hole to determine the setting position of the support member 43 on the pressing portion 421 .
示例地，定位结构44还可为设于按压部421上的定位柱，定位适配结构为开设于支撑件43上的定位孔，利用定位柱与定位孔相适配，以提升支撑件43在按压部421上的位置精度。For example, the positioning structure 44 can also be a positioning column provided on the pressing portion 421 , and the positioning adaptation structure can be a positioning hole opened on the support member 43 . The positioning column and the positioning hole are adapted to improve the position accuracy of the support member 43 on the pressing portion 421 .
请参考图6，在一个具体地实施例中，定位结构44包括定位孔，定位配合结构45包括定位柱，定位柱穿设于定位孔内。Please refer to FIG. 6 . In a specific embodiment, the positioning structure 44 includes a positioning hole, and the positioning matching structure 45 includes a positioning column. The positioning column is inserted into the positioning hole.
利用定位柱伸入定位孔内，以提升支撑件43与按压部421之间的连接稳定性。The positioning post is inserted into the positioning hole to improve the connection stability between the supporting member 43 and the pressing portion 421 .
可选地，如图6所示，在按压方向X上，按压部421的外形轮廓呈跑道形，此时，支撑件43的数量为两个，且关于按压部421的中心线呈对称设置，此时，在按压部421上开设有两个同样对称设置的定位孔，支撑件43上设有与通孔相适配的定位柱，当定位柱插设于对应的定位孔内时，则实现支撑件43在按压部421上的安装设置。Optionally, as shown in Figure 6, in the pressing direction X, the outer contour of the pressing portion 421 is runway-shaped. At this time, the number of support members 43 is two, and they are symmetrically arranged about the center line of the pressing portion 421. At this time, two positioning holes that are also symmetrically arranged are opened on the pressing portion 421, and a positioning column that is compatible with the through hole is provided on the support member 43. When the positioning column is inserted into the corresponding positioning hole, the installation setting of the support member 43 on the pressing portion 421 is realized.
请参考图7，在一些实施例中，定位柱与支撑件43一体成型，定位孔包括相连通的第一孔段441以及第二孔段442，第一孔段441的内径大于第二孔段442的内径，并且，第一孔段441远离于支撑件43。Please refer to Figure 7. In some embodiments, the positioning column and the support member 43 are integrally formed, and the positioning hole includes a first hole segment 441 and a second hole segment 442 that are connected. The inner diameter of the first hole segment 441 is larger than the inner diameter of the second hole segment 442, and the first hole segment 441 is far away from the support member 43.
这里，定位柱与支撑件43采用相同的材料制得，例如，二者均通过塑料、硅胶或橡胶等注塑而成。同时，支撑件43在与按键主体42相适配连接时，同样可采用注塑形成的方式来实现，例如，将已经成型好的按键主体42放置在模具中，即，采用模内注塑的方式，将定位柱直接成型于定位孔内。Here, the positioning column and the support member 43 are made of the same material, for example, both are formed by injection molding of plastic, silicone or rubber, etc. At the same time, when the support member 43 is adapted to be connected with the key body 42, it can also be formed by injection molding, for example, the already formed key body 42 is placed in a mold, that is, the positioning column is directly formed in the positioning hole by in-mold injection molding.
同时，通过调整第一孔段441的内径和第二孔段442的内径的大小，形成差异性设置，定位孔为台阶孔，那么，在进行模内注塑后，定位柱在第一孔段441内的直径大于其在第二孔段442内的直径，如此，在按压方向X上，支撑件43不易从按压部421上分离，能够进一步地支撑件43在按压部421上的连接稳定性。At the same time, by adjusting the size of the inner diameter of the first hole segment 441 and the inner diameter of the second hole segment 442, a differential setting is formed, and the positioning hole is a stepped hole. Then, after in-mold injection molding, the diameter of the positioning column in the first hole segment 441 is larger than its diameter in the second hole segment 442. In this way, in the pressing direction X, the support member 43 is not easily separated from the pressing portion 421, which can further enhance the connection stability of the support member 43 on the pressing portion 421.
请参考图7，在一些实施例中，第一孔段441的内径沿按压方向X逐渐减小。Please refer to FIG. 7 . In some embodiments, the inner diameter of the first hole segment 441 gradually decreases along the pressing direction X.
可以理解地，第一孔段441的孔壁呈锥状，更加便于加工，同时，定位柱在第一孔段441内的限位受力最小，也便于定位柱从第一孔段441内脱出。It can be understood that the hole wall of the first hole segment 441 is tapered, which is easier to process. At the same time, the limiting force of the positioning column in the first hole segment 441 is minimal, which also makes it easier for the positioning column to escape from the first hole segment 441.
请参考图6，在一些实施例中，支撑件43包括连接于按键主体42的连接部431以及由连接部431向外延伸的支撑部432，支撑部432背离连接部431的一端与外设结构101相过盈配合。Please refer to FIG. 6 . In some embodiments, the support member 43 includes a connecting portion 431 connected to the button body 42 and a supporting portion 432 extending outward from the connecting portion 431 . One end of the supporting portion 432 away from the connecting portion 431 is in interference fit with the peripheral structure 101 .
可以理解地，连接部431用于与按键主体42相连接，支撑部432则是用于与外设结构101相接触且与其进行过盈配合，如此，连接部431可为板状或块状结构，与按键主体42相贴合，支撑部432同样可为板状或块状结构，并且，支撑部432呈扩口结构，能够进一步提升对按键主体42的支撑，同时，支撑部432是直接与外设结构101相抵接而实现过盈配合的。It can be understood that the connecting portion 431 is used to connect with the key body 42, and the supporting portion 432 is used to contact the external structure 101 and perform an interference fit therewith. In this way, the connecting portion 431 can be a plate-like or block-like structure, which fits with the key body 42, and the supporting portion 432 can also be a plate-like or block-like structure. Moreover, the supporting portion 432 has a flared structure, which can further enhance the support for the key body 42. At the same time, the supporting portion 432 directly abuts against the external structure 101 to achieve an interference fit.
可选地，连接部431为板状结构，与按键主体42的按压部421的表面相贴合，支撑部432则呈扩口结构，对连接部431和按压部421进行支撑，在无外力作用下，连接部431和支撑部432将按键主体42衬托在外设结构101上。Optionally, the connecting portion 431 is a plate-like structure, which fits the surface of the pressing portion 421 of the key body 42, and the supporting portion 432 is a flared structure, which supports the connecting portion 431 and the pressing portion 421. In the absence of external force, the connecting portion 431 and the supporting portion 432 support the key body 42 on the peripheral structure 101.
请参考图6，在一些实施例中，支撑件43还包括抵接部433，抵接部433设于支撑部432远离连接部431的一端。Please refer to FIG. 6 . In some embodiments, the support member 43 further includes an abutting portion 433 . The abutting portion 433 is disposed at an end of the support portion 432 away from the connecting portion 431 .
可以理解地，本实施例中，支撑部432是与外设结构101相间接连接，即，支撑部432通过抵接部433与外设结构101相抵接，如此，抵接部433可增加支撑部432与外设结构101之间的接触面积。It can be understood that in this embodiment, the support portion 432 is indirectly connected to the external structure 101, that is, the support portion 432 abuts against the external structure 101 through the abutment portion 433, so that the abutment portion 433 can increase the contact area between the support portion 432 and the external structure 101.
请参考图3和图4，在一些实施例中，按键主体42通过支撑件43密封连接于外设结构101。Please refer to FIG. 3 and FIG. 4 . In some embodiments, the button body 42 is sealed and connected to the peripheral structure 101 through the support member 43 .
可以理解地，密封连接是指按键主体42与外设结构101之间间隙被支撑件43所填补，降低外界的水汽和灰尘从二者之间的间隙处进入支撑件43所围合的空间内，从而能够起到一定的防水防尘的功能。例如，在按压方向X上，支撑件43能够对按键主体42在外设结构101上的投影范围内的区域进行防水防尘。特别是，外设结构101上开设有孔结构等，可进一步地降低外部水汽或灰尘进入该孔结构内。It can be understood that the sealed connection means that the gap between the key body 42 and the peripheral structure 101 is filled by the support member 43, reducing the entry of external water vapor and dust from the gap between the two into the space enclosed by the support member 43, thereby being able to play a certain waterproof and dustproof function. For example, in the pressing direction X, the support member 43 can waterproof and dustproof the area within the projection range of the key body 42 on the peripheral structure 101. In particular, the peripheral structure 101 is provided with a hole structure, etc., which can further reduce the entry of external water vapor or dust into the hole structure.
可选地，当按键主体42置于外设结构101上时，按压部421与外设结构101之间形成存在一定的活动间隙，支撑件43则可密封封堵按压部421与外设结构101之间的间隙，具体的，支撑件43的连接部431贴合于按压部421朝向外设结构101的一侧，同时，支撑部432则朝向于外设结构101进行延伸，将整个环绕的活动间隙进行密封封堵。这里，密封封堵的压紧力来自于支撑部432抵接于外设结构101上的作用力。Optionally, when the button body 42 is placed on the peripheral structure 101, a certain movable gap is formed between the pressing portion 421 and the peripheral structure 101, and the support member 43 can seal and block the gap between the pressing portion 421 and the peripheral structure 101. Specifically, the connecting portion 431 of the support member 43 is attached to the side of the pressing portion 421 facing the peripheral structure 101, and at the same time, the support portion 432 extends toward the peripheral structure 101 to seal and block the entire surrounding movable gap. Here, the sealing and blocking pressure comes from the force of the support portion 432 abutting against the peripheral structure 101.
请参考图6，在一些实施例中，按键结构400还包括粘接层46，键帽41通过粘接层46连接于按键主体42。Please refer to FIG. 6 . In some embodiments, the key structure 400 further includes an adhesive layer 46 , and the key cap 41 is connected to the key body 42 via the adhesive layer 46 .
可以理解地，粘接工艺的连接方式更为简单和便捷，尤其适合在按压方向X上，按键主体42的投影位于键帽41内的情形。It can be understood that the connection method of the bonding process is simpler and more convenient, and is particularly suitable for the situation where the projection of the key body 42 is located inside the key cap 41 in the pressing direction X.
可选地，粘接层46可通过点胶的方式来实现。例如，在按键主体42的按压部421朝向键帽41的一侧进行点胶以形成粘接层46。Optionally, the adhesive layer 46 can be implemented by dispensing glue. For example, dispensing glue is performed on a side of the pressing portion 421 of the key body 42 facing the key cap 41 to form the adhesive layer 46.
可选地，粘接层46可通过贴合胶体的方式来实现。例如，在按键主体42的按压部421朝向键帽41的一侧的对应的位置贴合胶体。Optionally, the adhesive layer 46 can be implemented by laminating a colloid, for example, laminating a colloid at a corresponding position of the pressing portion 421 of the key body 42 facing the key cap 41 .
