背景技术Background technique
随着柔性折叠屏技术日趋成熟，柔性折叠终端产品已经成为一大趋势，折叠终端产品(如折叠手机、折叠平板、折叠电脑等电子设备)需要满足较高的可靠性，较好的操作体验及外观，这样才能被消费者所接受。折叠较链作为折叠终端产品的核心功能部件，其可靠性和操作体验很大程度取决于阻尼机构的性能。With the maturity of flexible folding screen technology, flexible folding terminal products have become a major trend. Folding terminal products (such as folding mobile phones, folding tablets, folding computers and other electronic equipment) need to meet high reliability, better operating experience and Appearance, so that it can be accepted by consumers. Folding hinges are the core functional components of folding terminal products, and their reliability and operating experience largely depend on the performance of the damping mechanism.
阻尼机构是内外折叠设备中提供用户开合手感的关键机构。目前的阻尼机构主要分为两类，即外挂阻尼和轴内阻尼。外挂阻尼在滑块内，采用多组弹簧顶住类球头结构在滑槽内移动，通过弹簧压缩量的变化实现不同的阻尼力。轴内阻尼方案则采用多组弹簧顶住凹凸轮结构，通过旋转轴转动，实现不同的弹簧压缩量，达到改变阻尼力的目的。然而，目前的阻尼结构零件较多，拆卸和装配复杂且存在一定难度，不仅成本高维修难度大，且不易进一步轻薄化。The damping mechanism is the key mechanism to provide the user with a feeling of opening and closing in the internal and external folding devices. The current damping mechanism is mainly divided into two categories, that is, external damping and in-shaft damping. The external damping is in the slider, and multiple sets of springs are used to withstand the ball-like structure to move in the chute, and different damping forces can be realized by changing the compression of the springs. The in-axis damping scheme uses multiple sets of springs to withstand the concave-cam structure, and through the rotation of the rotating shaft, different spring compressions can be achieved to achieve the purpose of changing the damping force. However, the current damping structure has many parts, and the disassembly and assembly are complicated and difficult. Not only is the cost high, the maintenance is difficult, and it is not easy to further reduce the thickness.

When the damping mechanism 40 is in the folded state/closed state (that is, the first damping unit and the second damping unit are relatively folded), the buckle 461 on the sliding claw 46 is located on the side walls 442 and 443 of the recessed portion 441 away from the center beam 41 side. The sliding process of the sliding claw 46 on the side walls 442 and 443 of the recessed portion 441 can be referred to in FIGS. Changes in position on the sidewalls.
如图6至图10所示，弹性件48分别与两个滑爪46连接。具体地，在滑爪46上设置有安装部462，弹性件48的两端分别与两个滑爪46的两个安装部462连接。安装部462设置在滑爪46中与卡扣461所在一侧相对的一侧上。即卡扣461和安装部462分别设置在滑爪46相对的两个侧面上。在安装部462上可以设置凹槽，弹性件48的端部可以固定在该凹槽中。具体固定方式可以卡合，粘结等方式，本申请不做具体限定。As shown in FIG. 6 to FIG. 10 , the elastic member 48 is connected to the two sliding claws 46 respectively. Specifically, the sliding claw 46 is provided with a mounting portion 462 , and the two ends of the elastic member 48 are respectively connected to the two mounting portions 462 of the two sliding claws 46 . The mounting portion 462 is disposed on a side of the sliding claw 46 opposite to the side where the buckle 461 is located. That is, the buckle 461 and the mounting portion 462 are respectively disposed on two opposite sides of the sliding claw 46 . A groove may be provided on the mounting portion 462, and the end of the elastic member 48 may be fixed in the groove. The specific fixing method can be engaged, bonded, etc., which is not specifically limited in this application.
如图6至图10所示，在阻尼机构40处于折叠状态时，弹性件48可处于未压缩状态或存在一定预压缩量，保证左滑舌42和右滑舌43与中梁41稳定配合，保持阻尼机构40、折叠铰链20和电子设备100处于折叠状态(即闭合状态)。在阻尼机构40处于展开状态时，弹性件48被压缩，其为两个滑爪46提供X方向的弹性力(或挤压力)，从而使卡扣461卡入凹陷部441侧壁上的卡槽444中，实现限位，保证电子设备100或柔性显示屏30处于展平状态。当用户使电子设备100或柔性显示屏30从展平状态变为中间状态或闭合状态时，需要施加克服卡扣461与卡槽444之间的阻尼力的作用力。As shown in Figures 6 to 10, when the damping mechanism 40 is in the folded state, the elastic member 48 can be in an uncompressed state or have a certain amount of pre-compression to ensure that the left sliding tongue 42 and the right sliding tongue 43 are in stable cooperation with the center beam 41, Keep the damping mechanism 40 , the folding hinge 20 and the electronic device 100 in the folded state (ie closed state). When the damping mechanism 40 is in the unfolded state, the elastic member 48 is compressed, which provides the elastic force (or extrusion force) in the X direction for the two sliding claws 46, so that the buckle 461 snaps into the snap on the side wall of the recessed portion 441. In the groove 444, the limit is realized to ensure that the electronic device 100 or the flexible display screen 30 is in a flattened state. When the user changes the electronic device 100 or the flexible display 30 from the flat state to the intermediate state or the closed state, it is necessary to apply a force to overcome the damping force between the buckle 461 and the slot 444 .
如图8至图9所示，在阻尼机构40从折叠状态到展开状态的过程中，滑爪46在凹陷部441的侧壁上滑动，且通过转动副47相对左滑舌42或右滑舌43转动，两个滑爪46之间的距离减小，弹性件48逐渐被压缩，因此弹性件48提供的作用力逐渐增加，阻尼机构40为电子设备100提供的阻尼力逐渐增加。图11示出了阻尼机构从展开状态变为折叠状态的过程中阻尼力的变化曲线图。其中，转角表示门板(左门板44或右门板45)相对中梁41的角度。转角为0度表示阻尼机构40处于展开状态，转角为90度时表示阻尼机构40处于折叠状态。如图11所示，在阻尼机构40从折叠状态到展开状态的过程中，阻尼机构40产生的阻尼力会随之逐渐增加。当阻尼力达到峰值F1后(此时滑爪46的卡扣461位于接近陷部441的卡槽444的位置处)，滑爪46的卡扣461卡入凹陷部441的卡槽444中，保持力将为F2。通过调节弹性件48在阻尼机构40从折叠状态到展开状态的过程中形变量，可以调节阻尼力峰值F1和保持力F2的大小。换言之，可以根据用户体验确定阻尼力峰值F1和保持力F2的大小，进而阻尼力峰值F1和保持力F2的大小设计弹性件48的几何尺寸，从而保证该阻尼机构40可实现良好的用户体验。As shown in Figures 8 to 9, during the process of the damping mechanism 40 from the folded state to the unfolded state, the sliding pawl 46 slides on the side wall of the recessed part 441, and relatively to the left sliding tongue 42 or the right sliding tongue through the rotating pair 47 43 rotates, the distance between the two sliding claws 46 decreases, and the elastic member 48 is gradually compressed, so the force provided by the elastic member 48 gradually increases, and the damping force provided by the damping mechanism 40 for the electronic device 100 gradually increases. Fig. 11 is a graph showing the variation of the damping force during the process of the damping mechanism changing from the unfolded state to the folded state. Wherein, the rotation angle represents the angle of the door panel (the left door panel 44 or the right door panel 45 ) relative to the center beam 41 . A rotation angle of 0 degrees indicates that the damping mechanism 40 is in an unfolded state, and a rotation angle of 90 degrees indicates that the damping mechanism 40 is in a folded state. As shown in FIG. 11 , during the process of the damping mechanism 40 from the folded state to the unfolded state, the damping force generated by the damping mechanism 40 will gradually increase accordingly. When the damping force reaches the peak value F1 (at this time, the buckle 461 of the sliding claw 46 is located at a position close to the groove 444 of the concave part 441), the buckle 461 of the sliding claw 46 is stuck in the groove 444 of the concave part 441, and the The force will be F2. By adjusting the amount of deformation of the elastic member 48 when the damping mechanism 40 changes from the folded state to the unfolded state, the peak value F1 of the damping force and the magnitude of the holding force F2 can be adjusted. In other words, the peak damping force F1 and the holding force F2 can be determined according to the user experience, and then the geometric dimensions of the elastic member 48 can be designed according to the peak damping force F1 and the holding force F2, so as to ensure that the damping mechanism 40 can achieve a good user experience.

请再次参阅图1至图3，折叠绞链20位于第一壳体11和第二壳体12之间，该折叠较链20能够使第一壳体11相对于第二壳体12产生靠近或远离第二壳体12的翻转运动。柔性显示屏30装配在第一壳体11、第二壳体12和折叠较链20的表面，并根据折叠较链20的转动随第一壳体11和第二壳体12产生翻转运动。Please refer to FIGS. 1 to 3 again, the folding hinge 20 is located between the first housing 11 and the second housing 12, and the folding hinge 20 can make the first housing 11 approach or close to the second housing 12 away from the overturning movement of the second housing 12 . The flexible display screen 30 is assembled on the surfaces of the first casing 11 , the second casing 12 and the hinge 20 , and produces flipping motion along with the first casing 11 and the second casing 12 according to the rotation of the hinge 20 .
应当理解的是，在该电子设备100中，第一支撑部21与第一壳体11固定连接，第二支撑部22与第二壳体12固定连接。当翻转第一壳体11时，第一壳体11带动第一支撑部21运动，第一支撑部21绕旋转部23运动，同理，在翻转第二壳体12时，第二壳体12带动第二支撑部22运动，第二支撑部22绕旋转部23运动，从而实现第一壳体11与第二壳体12的相对转动。同理，在转动时可同时朝相反方向翻动第一壳体11和第二壳体12，以实现第一壳体11和第二壳体12的分离或闭合。It should be understood that, in the electronic device 100 , the first support part 21 is fixedly connected to the first casing 11 , and the second support part 22 is fixedly connected to the second casing 12 . When the first casing 11 is turned over, the first casing 11 drives the first support part 21 to move, and the first support part 21 moves around the rotating part 23. Similarly, when the second casing 12 is turned over, the second casing 12 The second supporting part 22 is driven to move, and the second supporting part 22 moves around the rotating part 23 , so as to realize the relative rotation between the first housing 11 and the second housing 12 .

如图12至图14所示，本申请实施例提供的阻尼机构40包括两个阻尼单元50。阻尼单元50包括基体51以及设置在基体51远离旋转部23一侧的两个弹性臂52和53，在每个弹性臂远离基体51的一侧设置有卡扣54。基体51大致呈“冂”形状，其与旋转部23的转轴230转动连接。弹性臂52和53与第一支撑部21或第二支撑部22滑动连接，可以相对第一支撑部21或第二支撑部22滑动。弹性臂52和53由弹性材料制作，其可以相对基体弯曲，从而提供弹性力。示例性地，阻尼单元50可以一体成型。As shown in FIGS. 12 to 14 , the damping mechanism 40 provided by the embodiment of the present application includes two damping units 50 . The damping unit 50 includes a base body 51 and two elastic arms 52 and 53 disposed on a side of the base body 51 away from the rotating part 23 , and a buckle 54 is disposed on a side of each elastic arm away from the base body 51 .

在本申请实施例中，在第一支撑部21或第二支撑部22中设置有凹陷部24，凹陷部24大致呈梯形状。凹陷部24靠近旋转部23的一侧的X方向(电子设备100的长度方向或中梁41的延伸方向)的尺寸小于远离旋转部23的一侧的X方向的尺寸。换言之，凹陷部24在X方向的尺寸沿靠近旋转部23的方向逐渐减小。凹陷部24的两个侧壁241和242分别用作弹性臂52和53的滑轨，在第一支撑部21或第二支撑部22相对旋转部23转动的过程中，弹性臂52和53可以沿凹陷部24的侧壁241或242滑动。In the embodiment of the present application, a recessed part 24 is provided in the first support part 21 or the second support part 22 , and the recessed part 24 is roughly trapezoidal in shape. The dimension of the recessed portion 24 in the X direction (the length direction of the electronic device 100 or the extension direction of the center beam 41 ) on the side close to the rotating portion 23 is smaller than the dimension in the X direction on the side away from the rotating portion 23 . In other words, the size of the recessed portion 24 in the X direction gradually decreases along the direction approaching the rotating portion 23 . The two side walls 241 and 242 of the recessed part 24 are respectively used as slide rails for the elastic arms 52 and 53, and during the rotation of the first supporting part 21 or the second supporting part 22 relative to the rotating part 23, the elastic arms 52 and 53 can slide along the side wall 241 or 242 of the recessed portion 24 .
如图12至图14所示，在凹陷部24的侧壁241和242上设置有卡槽243，在弹性臂52和53设置有卡扣54。卡槽243设置在凹陷部24靠近旋转部23的一侧。卡扣54设置在弹性臂52和53远离旋转部23的一侧。如图12所示，当阻尼机构40处于展开状态(即两个阻尼单元50相对展开，或第一支撑部21和第二支撑部22相对展开)时，弹性臂52和53上的卡扣54卡入凹陷部24的侧壁241和242上的卡槽243中。当阻尼机构40处于折叠状态/闭合状态(即两个阻尼单元50相对折叠，或第一支撑部21和第二支撑部22相对折叠)时弹性臂52和53上的卡扣54位于凹陷部24的侧壁241和242上远离旋转部23的一侧。As shown in FIGS. 12 to 14 , locking grooves 243 are provided on the sidewalls 241 and 242 of the recessed portion 24 , and buckles 54 are provided on the elastic arms 52 and 53 . The locking slot 243 is disposed on a side of the concave portion 24 close to the rotating portion 23 . The buckle 54 is disposed on a side of the elastic arms 52 and 53 away from the rotating part 23 . As shown in FIG. 12 , when the damping mechanism 40 is in the deployed state (that is, the two damping units 50 are relatively deployed, or the first support part 21 and the second support part 22 are relatively deployed), the buckles 54 on the elastic arms 52 and 53 snap into the slots 243 on the side walls 241 and 242 of the recessed portion 24 . When the damping mechanism 40 is in the folded state/closed state (that is, the two damping units 50 are relatively folded, or the first support part 21 and the second support part 22 are relatively folded), the buckles 54 on the elastic arms 52 and 53 are located in the recessed part 24 The side of the side walls 241 and 242 away from the rotating part 23 .
在本申请实施例中，弹性臂52和53具有一定的弹性，其可以在X方向或转轴230的轴向上提供使弹性臂52和53相对凹陷部24向外运动或者使弹性臂52和53向彼此远离的方向运动的弹性力。换言之，以图12所示方位为例，弹性臂52具有向左运动的倾向，弹性臂53具有向右运动的倾向。也即弹性臂52和53具有对凹陷部24的侧壁的挤压力。在阻尼机构40或折叠铰链20从折叠状态转变为展开状态的过程中，弹性臂52和53相对凹陷部24沿侧壁向靠近旋转部23的方向滑动，在此过程中，弹性臂52和53彼此靠近，其施加在凹陷部24的侧壁上的挤压力逐渐增大。在弹性臂52和53的滑动过程中，由于挤压力的作用，弹性臂52和53与凹陷部24的侧壁形成滑动阻尼，该滑动阻尼可以在用户折叠或展开电子设备100时提供一定阻尼感，提高用户体验。在阻尼机构40或折叠铰链20从折叠状态转变为展开状态的过程中挤压力的变化或滑动阻尼的变化与图12所示的阻尼力的变化相似。当阻尼机构40或折叠铰链20处于展开状态时，弹性臂52和53上的卡扣54卡入凹陷部24的侧壁241和242上的卡槽243中，卡扣54与卡槽243的卡合也可提供一定阻尼作用，起到限位和防止反折(即防止展开状态变为折叠状态)的作用。当用户折叠电子设备100时，需要克服弹性臂52和53的挤压力以及卡扣54与卡槽243的卡合形成的阻尼力。In the embodiment of the present application, the elastic arms 52 and 53 have a certain degree of elasticity, which can provide the elastic arms 52 and 53 to move outward relative to the recessed part 24 or make the elastic arms 52 and 53 Elastic forces that move in directions away from each other. In other words, taking the orientation shown in FIG. 12 as an example, the elastic arm 52 has a tendency to move to the left, and the elastic arm 53 has a tendency to move to the right. That is, the elastic arms 52 and 53 have a pressing force against the sidewall of the recessed portion 24 . During the transition of the damping mechanism 40 or the folding hinge 20 from the folded state to the unfolded state, the elastic arms 52 and 53 slide relative to the recessed portion 24 in a direction close to the rotating portion 23 along the side wall. During this process, the elastic arms 52 and 53 Closer to each other, the pressing force exerted on the sidewall of the recessed portion 24 gradually increases. During the sliding process of the elastic arms 52 and 53, due to the extrusion force, the elastic arms 52 and 53 and the side walls of the recessed portion 24 form sliding damping, which can provide certain damping when the user folds or unfolds the electronic device 100 sense and improve user experience. During the transition of the damping mechanism 40 or the folding hinge 20 from the folded state to the unfolded state, the change of the extrusion force or the change of the sliding damping is similar to the change of the damping force shown in FIG. 12 . When the damping mechanism 40 or the folding hinge 20 is in the unfolded state, the buckles 54 on the elastic arms 52 and 53 snap into the slots 243 on the side walls 241 and 242 of the recess 24, and the snaps 54 and the slots 243 snap together. Closing can also provide a certain damping effect, and play the role of limiting and preventing reflexion (that is, preventing the unfolded state from changing to the folded state). When the user folds the electronic device 100 , it is necessary to overcome the pressing force of the elastic arms 52 and 53 and the damping force formed by the engagement of the buckle 54 and the slot 243 .
与图6至图12所示的阻尼机构和折叠铰链类似，在图12至14所示的阻尼机构和折叠铰链中，也可以根据用户体验设计弹性臂52和53的尺寸，并选择合适的材料，从而提供用户体验好的阻尼力。Similar to the damping mechanism and folding hinge shown in Figures 6 to 12, in the damping mechanism and folding hinge shown in Figures 12 to 14, the size of the elastic arms 52 and 53 can also be designed according to user experience, and suitable materials can be selected , so as to provide a good damping force for the user experience.

The base body 51 is generally in the shape of a "Xin", which is rotatably connected with the rotating shaft 230 of the rotating part 23 . The elastic arms 52 and 53 are slidably connected with the first support part 21 or the second support part 22 , and can slide relative to the first support part 21 or the second support part 22 .
