下面结合附图,通过具体的实施例及其应用场景对本申请实施例提供的折叠机构及电子设备进行详细地说明。The folding mechanism and the electronic device provided by the embodiments of the present application will be described in detail below through specific embodiments and application scenarios with reference to the accompanying drawings.

如图1至图10所示,本申请实施例公开一种铰链机构,铰链机构可以应用在电子设备中,使电子设备具备折叠的能力。电子设备通常包括显示屏820和屏幕支撑部810,屏幕支撑部810用以为显示屏820提供安装基础,且可以为显示屏820提供支撑作用。屏幕支撑部810的数量为多个,具体可以为两个、三个或更多个,为了便于理解,下文均与电子设备中包括两个屏幕支撑部810为例,对电子设备的具体结构和工作状态等情况进行介绍,至于屏幕支撑部810的数量为更多的实施方式,本领域技术人员可以根据本申请的技术思路相应拓展,此处不再详细介绍。As shown in FIG. 1 to FIG. 10 , the embodiment of the present application discloses a hinge mechanism, which can be applied in an electronic device, so that the electronic device has the ability to be folded. An electronic device generally includes adisplay screen 820 and ascreen support part 810 , thescreen support part 810 is used to provide an installation base for thedisplay screen 820 and can provide support for thedisplay screen 820 . The number ofscreen support parts 810 is multiple, specifically two, three or more. For the sake of easy understanding, the following will take the electronic device including twoscreen support parts 810 as an example, and the specific structure of the electronic device and The working status and other conditions will be introduced. As for the embodiment in which the number ofscreen support parts 810 is more, those skilled in the art can expand accordingly according to the technical ideas of the present application, and will not be described in detail here.

两个屏幕支撑部810之间通过铰链机构连接,在铰链机构的作用下,使得两个屏幕支撑部810之间具备相对运动的能力,进而使电子设备可以在折叠状态和展开状态相互切换。The twoscreen support parts 810 are connected by a hinge mechanism. Under the action of the hinge mechanism, the twoscreen support parts 810 have the ability to move relative to each other, so that the electronic device can switch between the folded state and the unfolded state.

在电子设备处于折叠状态的情况下,如图7所示,两个屏幕支撑部810层叠且相对设置,显示屏820位于两个屏幕支撑部810之间。当然,两个屏幕支撑部810可以呈相互平行的状态,或者,两个屏幕支撑部810之间亦可以存在数值相对较小的锐角。When the electronic device is in a folded state, as shown in FIG. 7 , twoscreen support parts 810 are stacked and arranged opposite to each other, and thedisplay screen 820 is located between the twoscreen support parts 810 . Of course, the twoscreen support portions 810 may be parallel to each other, or there may be a relatively small acute angle between the twoscreen support portions 810 .

在电子设备处于展开状态的情况下,如图5所示,显示屏820的显示面为一平面,两个屏幕支撑部810亦基本呈共面状态。当然,考虑加工精度以及显示屏820自身性质等因素的影响,处于展开状态的显示屏820的显示面可能并非为一绝对的平面结构,显示屏820中显示面的某些位置可能存在些许弯曲变形等,在这种情况下,亦可以认为显示屏820(或电子设备)处于展开状态。When the electronic device is in the unfolded state, as shown in FIG. 5 , the display surface of thedisplay screen 820 is a plane, and the twoscreen support parts 810 are basically coplanar. Of course, considering the influence of factors such as processing accuracy and the nature of thedisplay screen 820 itself, the display surface of thedisplay screen 820 in the unfolded state may not be an absolute planar structure, and some positions of the display surface in thedisplay screen 820 may have some bending deformation. etc. In this case, it can also be considered that the display screen 820 (or the electronic device) is in an unfolded state.

如上所述,在电子设备的使用过程中,显示屏820会随屏幕支撑部810的相对运动而发生变形,继而,显示屏820中的至少一部分为柔性结构。具体来说,显示屏820可以包括第一显示部、第二显示部和第三显示部,第一显示部和第二显示部通过第三显示部连接,使三者连为一个整体。可选地,第一显示部和第二显示部为硬质屏,以提升二者的使用寿命,第三显示部为柔性屏,且使第三显示部的位置对应于铰链机构的所在位置,保证第三显示部不会对铰链机构的正常弯折和展开动作产生妨碍。在本申请的另一实施例中,显示屏820可以整体为柔性屏,这亦可以保证显示屏820具备随铰链机构动作而变形的能力,且可以提升显示屏820的一致性,进而提升显示屏820的显示效果。As mentioned above, during the use of the electronic device, thedisplay screen 820 will be deformed with the relative movement of thescreen support part 810, and then at least a part of thedisplay screen 820 is a flexible structure. Specifically, thedisplay screen 820 may include a first display part, a second display part and a third display part, and the first display part and the second display part are connected through the third display part, so that the three are connected as a whole. Optionally, the first display part and the second display part are hard screens to increase their service life, the third display part is a flexible screen, and the position of the third display part corresponds to the position of the hinge mechanism, It is ensured that the third display part will not hinder the normal bending and unfolding actions of the hinge mechanism. In another embodiment of the present application, thedisplay screen 820 can be a flexible screen as a whole, which can also ensure that thedisplay screen 820 has the ability to deform with the action of the hinge mechanism, and can improve the consistency of thedisplay screen 820, thereby improving the display screen. 820 display effect.

Specifically, both thefirst connection part 210 and thesecond connection part 220 can form a fixed connection relationship with the correspondingscreen support part 810 by using a screw or the like. As for the actual structure and size of the first connectingportion 210 and the second connectingportion 220 , they can be determined according to the actual shape and size of other components such as thescreen support portion 810 in the electronic device, and are not limited here.

Correspondingly, the plurality of second connectingportions 220 are all distributed on the other side of the entire hinge mechanism, and the plurality of second connectingportions 220 are distributed along the aforementioned length direction of the entire hinge mechanism. The plurality offirst connection parts 210 and the plurality ofsecond connection parts 220 are fixedly connected to the correspondingscreen support parts 810 in the electronic device, so as to improve connection reliability and stress stability between adjacentscreen support parts 810 .

基座110可以采用金属或塑料等硬质材料形成,基座110是整个铰链机构中的基础部分,铰链机构中的其他结构均可以直接或间接地安装在基座110上,以与基座110形成连接关系。并且,铰链机构中的部件或结构大多是对称设置地,如第一转动部131,第一转动部131的数量为多个,多个第一转动部131均设置在基座110上。在排除所在位置等因素的影响之后,如图2所示,多个第一转动部131中包括两个在结构上对称设置的第一转动部131,两个第一转动部131中的一者用以与第一连接部210配合,另一者用以与第二连接部220配合。The base 110 can be formed by hard materials such as metal or plastic, and thebase 110 is the basic part in the whole hinge mechanism. form a connection. Moreover, most of the components or structures in the hinge mechanism are arranged symmetrically, such as the firstrotating part 131 , there are multiple firstrotating parts 131 , and the multiple firstrotating parts 131 are all arranged on thebase 110 . After excluding the influence of location and other factors, as shown in FIG. One is used to cooperate with the first connectingpart 210 , and the other is used to cooperate with the second connectingpart 220 .

相似地,用以与第一转动部131连接的第二转动部620的数量亦为多个,多个第二转动部620一一对应地与多个第一转动部131配合。多个第二转动部620中,包括两个第二转动部620与上述结构对称的两个第一转动部131一一对应配合,且形成转动连接关系,且两个第二转动部620中的一者与第一连接部210连接,另一者与第二连接部220连接。Similarly, there are also multiple secondrotating parts 620 for connecting with the firstrotating parts 131 , and the multiple secondrotating parts 620 match with the multiple firstrotating parts 131 in one-to-one correspondence.

Similarly, the secondsynchronous swing arm 420 can also be equipped with a mating gear, and the aforementioned mating gear meshes with thesecond gear 432, so that the secondsynchronous swing arm 420 can also form a transmission connection with thesecond gear 432 by means of the mating gear relation.

在上述实施例中,以第一同步摆臂410与对应的配合齿轮为例,二者之间可以通过焊接的方式在转动轴线的周向上形成相对固定关系。考虑铰链机构的后期维护情况,可以使第一同步摆臂410与对应的第一连杆720在第一转动部131的转动轴线的周向上相对固定,且使配合齿轮与第一连杆720在前述方向上亦形成相对固定关系。在这种情况下,即可保证第一同步摆臂410能够通过第一连杆720与配合齿轮在前述周向上形成相对固定关系。相似地,第二同步摆臂420与对应的配合齿轮亦可以采用上述技术方案在前述周向上形成相对固定关系。In the above embodiment, taking the firstsynchronous swing arm 410 and the corresponding matching gear as an example, the two can form a relatively fixed relationship in the circumferential direction of the rotation axis by means of welding.

如上所述,第一同步摆臂410和第二同步摆臂420分别与第一连接部210和第二连接部220连接,由于第一同步摆臂410和对应的第一转动部131的转动轴线不同,进而在第一同步摆臂410随第一连接部210以第一转动部131的轴线转动的过程中,还会使得第一同步摆臂410与第一连接部210产生相对运动。基于此,可以使第一同步摆臂410与第一连接部210形成滑动配合关系,例如,第一同步摆臂410与第一连接部210之间可以通过滑动配合的滑套和销轴形成滑动连接关系,滑套设有轨道,销轴穿设于滑套中,且沿轨道相对滑套运动。As mentioned above, the firstsynchronous swing arm 410 and the secondsynchronous swing arm 420 are respectively connected with the first connectingpart 210 and the second connectingpart 220 , due to the rotation axes of the firstsynchronizing swing arm 410 and the corresponding firstrotating part 131 It is different, and furthermore, when the firstsynchronous swing arm 410 rotates with the first connectingpart 210 along the axis of the firstrotating part 131 , the firstsynchronous swing arm 410 and the first connectingpart 210 will also move relative to each other. Based on this, the firstsynchronous swing arm 410 and the first connectingportion 210 can form a sliding fit relationship, for example, the firstsynchronizing swing arm 410 and the first connectingportion 210 can form a sliding fit through a sliding sleeve and a pin shaft. In the connection relationship, the sliding sleeve is provided with a track, and the pin shaft is passed through the sliding sleeve, and moves relative to the sliding sleeve along the track.

在本申请的另一实施例中,以第一同步摆臂410为例,如图2所示,第一同步摆臂410可以包括同步臂411和滑座412,第一连接部210设有滑槽211,其中,同步臂411通过第一连杆720与基座110转动连接,滑座412与第一连接部210的滑槽211滑动配合。In another embodiment of the present application, taking the firstsynchronous swing arm 410 as an example, as shown in FIG.slot 211 , wherein thesynchronization arm 411 is rotationally connected to the base 110 through the first connectingrod 720 , and the slidingseat 412 is slidingly matched with the slidingslot 211 of the first connectingportion 210 .

基于上述结构,进一步地,如图2所示,沿第一转动部131的转动轴线所在的方向,可以使滑座412的尺寸大于同步臂411的尺寸。在采用本申请实施例的情况下,还可以提升第一连接部210与第一同步摆臂410之间的连接可靠性。Based on the above structure, further, as shown in FIG. 2 , along the direction of the rotation axis of the firstrotating part 131 , the size of the slidingseat 412 can be made larger than the size of thesynchronization arm 411 . In the case of adopting the embodiment of the present application, the connection reliability between the first connectingportion 210 and the firstsynchronous swing arm 410 can also be improved.

为了防止第一同步摆臂410与第一连杆720在转动轴线所在的方向上相对运动,从而对第一同步摆臂410与第一齿轮431(或第二同步摆臂420)之间的传动连接关系产生不利影响,可选地,本申请实施例公开的铰链机构还可以包括第一弹性件(图中未示出),在第一转动部131的转动轴线所在的方向上,第一弹性件连接于基座110和第一同步摆臂410之间,以利用第一弹性件使第一同步摆臂410与基座110在第一转动部131的转动轴线所在的方向形成挤压配合关系,进而限制第一同步摆臂410的自主转动,使铰链机构具备阻尼感。同时,在第一弹性件的作用下,还可以防止第一同步摆臂410相对基座110沿前述转动轴线所在的方向相对基座110运动。In order to prevent the relative movement of the firstsynchronous swing arm 410 and the first connectingrod 720 in the direction of the rotation axis, the transmission between the firstsynchronous swing arm 410 and the first gear 431 (or the second synchronous swing arm 420 ) The connection relationship has adverse effects.

At the same time, under the action of the first elastic member, the firstsynchronous swing arm 410 can also be prevented from moving relative to the base 110 in the direction where the aforementioned rotation axis is located.

具体地,第一弹性件与第一同步摆臂410之间可以形成抵接或固定连接等直接连接关系,或者,二者之间还可以通过其他结构件间接连接在一起,以使第一弹性件的弹性力能够作用至第一同步摆臂410上。通过使第一弹性件始终处于被挤压状态或被拉伸状态,使得铰链机构无论处于何种展开角度的情况下,均能够使第一同步摆臂410被挤压于基座110上,进而使第一同步摆臂410始终具有阻尼感;或者,还可以通过增设其他结构件,且在铰链机构处于某些角度范围内时,才使第一同步摆臂410与基座110相互挤压,而在铰链机构处于其他角度范围内时,则可以使第一同步摆臂410与基座110之间基本不存在相互挤压的情况。Specifically, the first elastic member and the firstsynchronous swing arm 410 can form a direct connection relationship such as abutment or fixed connection, or the two can also be indirectly connected together through other structural members, so that the first elastic The elastic force of the component can act on the firstsynchronous swing arm 410 . By making the first elastic member always in the squeezed state or stretched state, no matter what the unfolding angle of the hinge mechanism is, the firstsynchronous swing arm 410 can be squeezed on thebase 110, and then Make the firstsynchronous swing arm 410 always have a sense of damping; or, by adding other structural components, and when the hinge mechanism is within a certain angle range, the firstsynchronous swing arm 410 and the base 110 are pressed against each other, However, when the hinge mechanism is in other angle ranges, there is basically no mutual extrusion between the firstsynchronous swing arm 410 and thebase 110 .

更具体地说,第一弹性件处于拉伸或压缩状态,以挤压第一同步摆臂410和基座110中与第一同步摆臂410贴合的表面。在本实施例中,基座110可以设置有缺口,且使第一同步摆臂410与第一弹性件均设置于前述缺口内,从而使基座110的前述缺口中朝向第一同步摆臂410的第一侧壁与第一同步摆臂410贴合,且使第一弹性件的两端分别抵接在第一同步摆臂410和基座110的前述缺口的第二侧壁上,第二侧壁与第一侧壁沿转动轴线所在的方向相对设置。当然,第一弹性件的设置位置和连接形式还有多种组合,此处不再一一介绍。More specifically, the first elastic member is in a stretched or compressed state, so as to press the firstsynchronous swing arm 410 and the surface of the base 110 that is attached to the firstsynchronous swing arm 410 .

并且,限位件朝向第一同步摆臂410的一端设有多个沿转动轴线的周向(也即,围绕转动轴线的方向)间隔设置的第一限位凸起(图中未示出),对应地,第一同步摆臂410朝向限位件的一端设有多个沿转动轴线的周向间隔设置的第二限位凸起(图中未示出)。Moreover, one end of the limiting member facing the firstsynchronous swing arm 410 is provided with a plurality of first limiting protrusions (not shown in the figure) arranged at intervals along the circumferential direction of the rotation axis (that is, the direction around the rotation axis). Correspondingly, the end of the firstsynchronous swing arm 410 facing the limiting member is provided with a plurality of second limiting protrusions (not shown in the figure) arranged at intervals along the circumference of the rotation axis.

多个第一限位凸起中的任一第一限位凸起均可以卡持于多个第二限位凸起中任意相邻的两个之间的间隙内,且多个第二限位凸起中的任一第二限位凸起均可以卡持于多个第一限位凸起中任意相邻的两个之间的间隙内,从而在第一同步摆臂410和限位件沿转动轴线的周向相对转动的过程中,通过第一限位凸起和第二限位凸起,不仅可以使限位件与第一同步摆臂410能够在转动轴线的周向上转动配合,还可以使限位件和第一同步摆臂410能够在转动轴线所在的方向活动配合,前述活动配合具体为沿转动轴线所在的方向往复运动。Any one of the plurality of first position-limiting protrusions can be held in the gap between any adjacent two of the plurality of second position-limiting protrusions, and the plurality of second position-limiting protrusions Any second position-limiting protrusion in the positioning protrusions can be clamped in the gap between any adjacent two of the plurality of first position-limiting protrusions, so that the firstsynchronous swing arm 410 and the position-limiting During the relative rotation of the part along the circumferential direction of the rotation axis, through the first stop protrusion and the second stop protrusion, not only can the stop part and the firstsynchronous swing arm 410 be able to rotate and cooperate with each other in the circumferential direction of the rotation axis , the limiter and the firstsynchronous swing arm 410 can also be movable in the direction of the rotation axis, and the above-mentioned movable cooperation is specifically a reciprocating movement in the direction of the rotation axis.

在上述实施例中,可以使限位件和第一同步摆臂410中的一者与第一弹性件的一端连接,且可以使基座110和定位件中的一者与第一弹性件的另一端连接,根据与第一弹性件连接的部件的具体情况,对应设定第一弹性件的压缩或拉伸状态,即可在第一转动部131的转动轴线所在的方向上,使限位件和第一同步摆臂410处于被挤压的状态。如上所述,在限位件位于第一同步摆臂410和定位件之间的情况下,第一弹性件的相背两端可以分别抵接于限位件和定位件之间。In the above embodiment, one of the limiting member and the firstsynchronous swing arm 410 can be connected to one end of the first elastic member, and one of thebase 110 and the positioning member can be connected to one end of the first elastic member. The other end is connected, and according to the specific conditions of the parts connected to the first elastic member, the compression or stretching state of the first elastic member is correspondingly set, that is, in the direction where the rotation axis of the firstrotating part 131 is located, the position-limiting The component and the firstsynchronous swing arm 410 are in a squeezed state. As mentioned above, when the limiting member is located between the firstsynchronous swing arm 410 and the positioning member, opposite ends of the first elastic member may abut between the limiting member and the positioning member respectively.

更具体地,在第一限位凸起位于相邻的两个第二限位凸起之间,且第一限位凸起的相背两侧分别与其相背两侧的两个第二限位凸起接触这种配合状态下,可以使第一弹性件处于自然状态。同时,除上述配合状态之外的其他状态,均可以使第一弹性件处于拉伸或被挤压状态,进而保证第一弹性件具有使第一限位凸起和第二限位凸起处于前述配合状态的趋势,以及趋向于向前述配合状态转换的趋势。More specifically, when the first limiting protrusion is located between two adjacent second limiting protrusions, and the two opposite sides of the first limiting protrusion are respectively connected to the two second limiting protrusions on the opposite sides. In this mating state where the bit protrusions are in contact, the first elastic member can be in a natural state. At the same time, in other states except the above-mentioned mating state, the first elastic member can be in a stretched or squeezed state, thereby ensuring that the first elastic member has the ability to make the first position-limiting protrusion and the second position-limiting protrusion Tendency to the aforementioned mating state, and tendency towards transition to the aforementioned mating state.

在采用上述技术方案的情况下,如果第一同步摆臂410和限位件未受到外力作用,铰链机构能够稳定地处于至少一种特定角度的状态。当然,在设计第一限位凸起和第二限位凸起的具体结构的过程中,还需要保证在铰链机构处于展开状态和折叠状态时,第一限位凸起和第二限位凸起能够处于前述配合状态,从而使铰链机构能够稳定地悬停在展开状态、折叠状态和前述两种状态之间的至少另一其他角度,以扩大电子设备的使用场景,提升用户体验。In the case of adopting the above technical solution, if the firstsynchronous swing arm 410 and the limiting member are not subjected to external force, the hinge mechanism can be stably in a state of at least one specific angle. Of course, in the process of designing the specific structure of the first position-limiting protrusion and the second position-limiting protrusion, it is also necessary to ensure that when the hinge mechanism is in the expanded state and the folded state, the first position-limiting protrusion and the second position-limiting protrusion The hinge mechanism can be in the aforementioned mating state, so that the hinge mechanism can stably hover at least another angle between the unfolded state, the folded state, and the aforementioned two states, so as to expand the usage scenarios of electronic devices and improve user experience.

如上所述,在铰链机构处于第二状态的情况下,第一连接部210和第二连接部220均位于基座110朝向自身屏幕支撑侧的一侧,也即,铰链机构适用于内折式电子设备。在这类电子设备处于折叠状态时,需要利用铰链机构为显示屏820提供容纳空间,保证显示屏820不会被铰链机构中相对运动的部件所挤压。As mentioned above, when the hinge mechanism is in the second state, both the first connectingpart 210 and the second connectingpart 220 are located on the side of the base 110 facing its own screen support side, that is, the hinge mechanism is suitable for inward folding Electronic equipment. When this type of electronic device is in a folded state, the hinge mechanism needs to be used to provide accommodating space for thedisplay screen 820 to ensure that thedisplay screen 820 will not be squeezed by relatively moving parts in the hinge mechanism.

同时,在上述实施例中,可以通过设置具备与基座110相对运动能力的浮动支撑部300为显示屏820提供避让作用,更具体地,在铰链机构设有浮动支撑部300的情况下,如图2和图3所示,可以为浮动支撑部300配设第二弹性件520,也即,本申请实施例公开的铰链机构还可以包括第二弹性件520,第二弹性件520可以连接在浮动支撑部300与基座110之间。并且,在铰链机构处于第一状态的情况下,使多个第二转动部620中的至少一者支撑浮动支撑部300的同时,挤压或拉伸第二弹性件520,以挤压浮动支撑部300和第二转动部620。具体地,如图3所示,通过螺钉510等部件可以将第二弹性件520组装在浮动支撑部300和基座110之间,且使第二弹性件520被挤压在螺钉510和基座110之间。At the same time, in the above-mentioned embodiment, it is possible to provide avoidance for thedisplay screen 820 by setting the floatingsupport portion 300 capable of moving relative to thebase 110. More specifically, when the hinge mechanism is provided with the floatingsupport portion 300, as shown in As shown in Figures 2 and 3, a secondelastic member 520 may be provided for the floatingsupport part 300, that is, the hinge mechanism disclosed in the embodiment of the present application may also include a secondelastic member 520, and the secondelastic member 520 may be connected to Between the floatingsupport part 300 and thebase 110 . And, when the hinge mechanism is in the first state, at least one of the plurality of secondrotating parts 620 supports the floating supportingpart 300, and at the same time, squeezes or stretches the secondelastic member 520 to squeeze the floating supportingpart 300.part 300 and the secondrotating part 620. Specifically, as shown in FIG. 3 , the secondelastic member 520 can be assembled between the floatingsupport part 300 and the base 110 throughscrews 510 and other components, and the secondelastic member 520 is pressed between thescrew 510 and the base. Between 110.

进而,在铰链机构处于第二状态的情况下,由于第二转动部620避让浮动支撑部300,进而使得浮动支撑部300能够在第二弹性件520的弹性作用下复位,也即,使浮动支撑部300向靠近基座110的方向运动,进而使浮动支撑部300与基座110之间的间距减小,提升浮动支撑部300的自动化能力,且可以进一步防止浮动支撑部300挤压显示屏820。Furthermore, when the hinge mechanism is in the second state, since the secondrotating part 620 avoids the floatingsupport part 300, the floatingsupport part 300 can be reset under the elastic action of the secondelastic member 520, that is, the floating support Thepart 300 moves toward the direction close to thebase 110, thereby reducing the distance between the floatingsupport part 300 and thebase 110, improving the automation capability of the floatingsupport part 300, and further preventing the floatingsupport part 300 from pressing thedisplay screen 820 .

在本申请的另一实施例中,为了防止显示屏820随铰链机构折叠时出现被挤压的情况,在本申请实施例公开的铰链机构包括支撑板610的情况下,还可以使第一连接部210与对应的支撑板610形成转动连接关系,进而使二者具备相对转动的能力。当然,由于第二连接部220和第一连接部210基本呈对称式结构,第二连接部220与对应的支撑板610之间的配合关系可以参照第一连接部210。In another embodiment of the present application, in order to prevent thedisplay screen 820 from being squeezed when the hinge mechanism is folded, when the hinge mechanism disclosed in the embodiment of the present application includes thesupport plate 610, the first connection can also be made Thepart 210 forms a rotational connection with thecorresponding support plate 610, so that the two have the ability to rotate relative to each other. Of course, since the second connectingportion 220 and the first connectingportion 210 are substantially symmetrical in structure, the matching relationship between the second connectingportion 220 and thecorresponding support plate 610 can refer to the first connectingportion 210 .

在第一连接部210与支撑板610具备相对转动的能力的情况下,可以利用显示屏820挤压支撑板610的方式,使支撑板610能够相对第一连接部210转动,以在显示屏820被折叠的过程中避让显示屏820。In the case that the first connectingportion 210 and the supportingplate 610 have the ability to rotate relative to each other, the supportingplate 610 can be rotated relative to the first connectingportion 210 by using thedisplay screen 820 to squeeze the supportingplate 610, so that thedisplay screen 820Avoid display screen 820 during being folded.

基于第一连接部210和支撑板610具备相对转动的能力的技术方案,在铰链机构处于第一状态的情况下,各支撑板610均支撑于基座110,且各支撑板610背离基座110的第一表面共面,从而使得与第一连接部210(和第二连接部220)具备相对转动的支撑板610能够通过支撑在基座110上的方式,为显示屏820中对应的部分提供可靠的支撑作用。Based on the technical solution that the first connectingportion 210 and thesupport plate 610 have the ability to rotate relative to each other, when the hinge mechanism is in the first state, eachsupport plate 610 is supported on thebase 110, and eachsupport plate 610 is away from thebase 110 The first surface is coplanar, so that the supportingplate 610 that has relative rotation with the first connecting part 210 (and the second connecting part 220 ) can be supported on the base 110 to provide the corresponding part of thedisplay screen 820 Reliable support.

当然,在前述状态下,相邻的两个支撑板610相互靠近的一端与对应的第一连接部210(和第二连接部220)之间均有间隔,以保证在铰链机构自第一状态切换至第二状态的过程中,第一连接部210能够和对应的支撑板610产生相对转动,从而使相邻的两个支撑板610之间的相对转动角度大于第一连接部210和第二连接部220之间相对转动的角度,进而利用支撑板610的外扩作用,为显示屏820提供避让空间,防止显示屏820在被折叠的过程中,以及处于折叠状态时被支撑板610所挤压而损坏。Of course, in the aforementioned state, there is a distance between the adjacent ends of the twoadjacent support plates 610 and the corresponding first connecting portion 210 (and the second connecting portion 220), so as to ensure In the process of switching to the second state, the first connectingpart 210 can generate relative rotation with thecorresponding support plate 610, so that the relative rotation angle between twoadjacent support plates 610 is larger than that between the first connectingpart 210 and the second The relative rotation angle between the connectingparts 220, and then use the outward expansion of thesupport plate 610 to provide an avoidance space for thedisplay screen 820, preventing thedisplay screen 820 from being squeezed by thesupport plate 610 during the process of being folded and in the folded state. damaged by pressure.

对应地,在铰链机构处于第二状态的情况下,第一连接部210和第二连接部220均支撑各自对应的支撑板610,也即,与第一连接部210对应的支撑板610支撑在第一连接部210上,与第二连接部220对应的支撑板610支撑在第二连接部220上,且使两个相对设置的支撑板610各自的第一表面形成扩口状结构,且扩口朝向基座110。Correspondingly, when the hinge mechanism is in the second state, both the first connectingportion 210 and the second connectingportion 220 support their respective supportingplates 610, that is, the supportingplates 610 corresponding to the first connectingportion 210 are supported on On the first connectingpart 210, the supportingplate 610 corresponding to the second connectingpart 220 is supported on the second connectingpart 220, and the first surfaces of the two opposite supportingplates 610 are formed into a flaring structure, and the expanding The mouth faces thebase 110 .

具体来说,如上述铰链机构处于第一状态时,相邻的两个支撑板610中用以支撑显示屏820的第一表面共面,随着第一连接部210和第二连接部220相对转动,通过使第一连接部210与对应的支撑板610亦能够相对转动,且使第二连接部220与对应的支撑板610相对转动,使得前述相邻的两个支撑板610各自转动的角度能够超过90°,进而使得相邻的两个支撑板610中靠近基座110的侧边之间的间距大于相邻的两个支撑板610中远离基座110的侧边之间的间距,达到使两个支撑板610形成前述扩口状结构,且扩口朝向基座110的目的。Specifically, when the aforementioned hinge mechanism is in the first state, the first surfaces used to support thedisplay screen 820 in twoadjacent support plates 610 are coplanar, and as the first connectingportion 210 and the second connectingportion 220 face each other Rotate, by making thefirst connection part 210 and thecorresponding support plate 610 can also rotate relatively, and make thesecond connection part 220 and thecorresponding support plate 610 rotate relatively, so that the aforementioned twoadjacent support plates 610 respectively rotate the angle It can be more than 90°, so that the distance between the sides close to the base 110 in the twoadjacent support plates 610 is greater than the distance between the sides far away from the base 110 in the twoadjacent support plates 610, reaching The twosupport plates 610 form the aforementioned flaring structure, and the flaring faces the purpose of thebase 110 .

在采用上述技术方案的情况下,由于切换至第二状态的铰链机构的支撑板610能够向远离显示屏820的方向运动,从而可以为显示屏820提供避让作用,使得显示屏820在被折叠的过程中,以及处于折叠状态时,均基本不会被支撑板610(或整个铰链机构)挤压。In the case of adopting the above technical solution, since thesupport plate 610 of the hinge mechanism switched to the second state can move away from thedisplay screen 820, it can provide avoidance for thedisplay screen 820, so that thedisplay screen 820 is folded During the process, and in the folded state, it is basically not squeezed by the support plate 610 (or the entire hinge mechanism).

更具体地,可以使第一连接部210和第二连接部220二者朝向支撑板610的一侧表面设置为斜面,从而在铰链机构动作的过程中,能够使支撑板610相对第一连接部210转动预设角度,且支撑在第一连接部210上。并且,如图2所示,支撑板610和第一连接部210可以通过第二连杆710相互连接,且使二者形成转动配合关系。More specifically, both the first connectingportion 210 and the second connectingportion 220 can be set as inclined surfaces on one side facing thesupport plate 610, so that thesupport plate 610 can be positioned opposite to the first connecting portion during the action of the hinge mechanism. 210 rotates at a preset angle and is supported on the first connectingportion 210 . Moreover, as shown in FIG. 2 , thesupport plate 610 and the first connectingportion 210 may be connected to each other through the second connectingrod 710 , so that the two form a rotational fit relationship.
