联动机构26弯折时，将其中一连杆件261朝向另一连接杆261转动，所述其中一连杆件261的第一齿轮2661沿对应的第二齿轮2663转动；由于固定件262的固定块2621与第二连接轴2620之间相对固定，第二齿轮2663固定于固定块2621上，因此，第二齿轮2663固定不会转动，第一齿轮2661只能绕对应的第二齿轮2663转动，以使所述其中一连杆件261沿对应的第二齿轮2663转动，从而一并带动连接于所述其中一连杆件261上的两个传动件264沿对应的第二连接轴2620转动及一并带动对应的阻尼件268沿对应的第二连接轴2620转动；所述两个传动件264通过第二齿轮组件267一并带动另外两个传动件264沿对应的第二连接轴2620转动，所述另外两个传动件264带动另一个连杆件261绕对应的第二齿轮2663转动，从而使两个连杆件261同时相互靠近而折弯。在此联动过程中，由于每一第一连接轴2610及第二连接轴2620与对应的阻尼片2681的阻尼孔2683过盈配合，因此，阻尼件268能将两个连杆件261转动定位于任意角度。When the linkage mechanism 26 is bent, one of the connecting rods 261 is rotated toward the other connecting rod 261, and the first gear 2661 of the one of the connecting rods 261 rotates along the corresponding second gear 2663; due to the fixing of the fixing member 262 The block 2621 and the second connecting shaft 2620 are relatively fixed, and the second gear 2663 is fixed on the fixed block 2621. Therefore, the second gear 2663 is fixed and does not rotate. The first gear 2661 can only rotate around the corresponding second gear 2663. In order to make one of the connecting rod members 261 rotate along the corresponding second gear 2663, so as to drive the two transmission members 264 connected to the one of the connecting rod members 261 to rotate along the corresponding second connecting shaft 2620. Drive the corresponding damping member 268 to rotate along the corresponding second connecting shaft 2620 together; the two transmission members 264 simultaneously drive the other two transmission members 264 to rotate along the corresponding second connecting shaft 2620 through the second gear assembly 267, The other two transmission members 264 drive the other connecting rod member 261 to rotate around the corresponding second gear 2663, so that the two connecting rod members 261 are simultaneously close to each other and bend. During this linkage process, since each of the first connecting shaft 2610 and the second connecting shaft 2620 is in interference fit with the orifice 2683 of the corresponding damping plate 2681, the damping member 268 can rotate and position the two connecting rod members 261 at Any angle.

当联动机构26由弯折状态展平时，将其中一连杆件261朝远离另一连接杆261转动，所述其中一连杆件261的第一齿轮2661沿对应的第二齿轮2663转动；由于固定件262的固定块2621与第二连接轴2620之间相对固定，具第二齿轮2663固定于固定块2621上，因此，第二齿轮2663固定不会转动，第一齿轮2661只能绕对应的第二齿轮2663转动，以使所述其中一连杆件261沿对应的第二齿轮2663朝远离另一连接杆261转动，以带动连接于所述其中一连杆件261上的两个传动件264沿对应的第二连接轴2620朝相互远离的方向转动及带动对应的阻尼件268沿对应的第二连接轴2620朝相互远离的方向转动；所述两个传动件264通过第二齿轮组件267带动另外两个传动件264沿对应的第二连接轴2620转动，所述另外两个传动件264带动另一个连杆件261绕对应的第二齿轮2663朝远离所述其中一连杆件261转动，从而使两个连杆件261同时相互远离而展平。在此联动过程中，由于每一第一连接轴2610及第二连接轴2620与对应的阻尼片2681的阻尼孔2683过盈配合，因此，阻尼件268能将两个连杆件261转动定位于任意角度。When the linkage mechanism 26 is flattened from the bent state, one of the connecting rods 261 is rotated away from the other connecting rod 261, and the first gear 2661 of one of the connecting rods 261 rotates along the corresponding second gear 2663; The fixing block 2621 of the fixing member 262 is relatively fixed to the second connecting shaft 2620, and the second gear 2663 is fixed on the fixing block 2621. Therefore, the second gear 2663 is fixed and does not rotate, and the first gear 2661 can only rotate around the corresponding The second gear 2663 rotates so that one of the connecting rods 261 rotates away from the other connecting rod 261 along the corresponding second gear 2663 to drive the two transmission parts connected to the one of the connecting rods 261 264 rotates away from each other along the corresponding second connecting shaft 2620 and drives the corresponding damping member 268 to rotate away from each other along the corresponding second connecting shaft 2620; the two transmission members 264 pass through the second gear assembly 267 Drive the other two transmission members 264 to rotate along the corresponding second connecting shaft 2620, and the other two transmission members 264 drive the other link member 261 to rotate around the corresponding second gear 2663 away from the one of the link members 261 , So that the two connecting rod members 261 are simultaneously separated from each other and flattened. During this linkage process, since each of the first connecting shaft 2610 and the second connecting shaft 2620 is in interference fit with the orifice 2683 of the corresponding damping plate 2681, the damping member 268 can rotate and position the two connecting rod members 261 at Any angle.
在其他的使用方式中，可以将两个连杆件261朝相反方向一同转动实现由弯折状态至展平状态的改变，具体的，两个连杆传261的第一齿轮2661绕对应的第二齿轮2663转动，以带动传动件264沿对应的第二连接轴2620朝相反方向转动，且带动两个阻尼件268沿对应的第二连接轴2620朝相反方向转动，从而使两个连杆件261同时相互远离而展平。In other modes of use, the two connecting rods 261 can be rotated together in opposite directions to realize the change from the bent state to the flattened state. Specifically, the first gear 2661 of the two connecting rods 261 rotates around the corresponding first gear 2661. The second gear 2663 rotates to drive the transmission member 264 to rotate in the opposite direction along the corresponding second connecting shaft 2620, and to drive the two damping members 268 to rotate in the opposite direction along the corresponding second connecting shaft 2620, so that the two connecting rods 261 at the same time move away from each other and flatten out.

Specifically, each connecting hinge 251 is hinged with the corresponding The rotating hinges 253 rotate through a first virtual axis A1, and the two rotating hinges 253 rotate through a second virtual axis A2. The second virtual axis A2 is located between the two first virtual axes A1. The distances between the two first virtual axes A1 and the second virtual axis A2 are the same. The two connecting hinges 251 respectively rotate about the corresponding first virtual axis A1, the first positioning component 28a and the second positioning component 28b also rotate with the corresponding connecting hinge 251 about the first virtual axis A1; two rotating hinges 253 Respectively rotate around the second virtual axis A2, the first transmission assembly 271 and the corresponding connecting cover 270 and the third transmission assembly 277 rotate with the corresponding rotating hinge 253 around the second virtual axis A2, and the second transmission assembly 274 is connected to the corresponding The cover 270 and the third transmission assembly 277 rotate with the corresponding rotating hinge 253 around the second virtual axis A2. Specifically, since the first transmission component 271, the corresponding connecting cover 270, the third transmission component 277 connected to the connecting cover 270, and the corresponding rotating hinge 253 are connected in an integrated structure, the integrated structure is wound around the first The second virtual axis A2 rotates; since the second transmission component 274, the corresponding connecting cover 270, the third transmission component 277 connected to the connecting cover 270, and the corresponding rotating hinge 253 are connected to an integrated structure, the integrated structure The structure also rotates about the second virtual axis A2. Each first virtual axis A1 is spaced parallel to the second virtual axis A2, and the axis radius of the first virtual axis A1 is the same as the axis radius of the second virtual axis A2. In the flat state, the distance between the two opposite side surfaces of the two connecting hinges 251 is L, that is, the linear distance between the two connecting hinges 251 on the bent outer sides of the two connecting hinges 251 when they are flattened is L. In this embodiment, the distance between the two opposite sides of the two connecting hinges 251 is equal to the width of the bendable area 31, that is, the length of the bendable area 31 extending in the direction perpendicular to the first virtual axis A1 is equal to L . The first virtual axis A1 and the second virtual axis A2 are both located outside the hinge body 25. Preferably, the first virtual axis A1 and the second virtual axis A2 are both located on the flexible screen 30 covering the hinge body 25, thereby improving The bending resistance of the flexible screen 30 can ensure that the flexible screen 30 is not damaged to the greatest extent. Further, A1 and A2 can also be located on the neutral layer of the flexible screen.
所述中性层是指柔性屏30在弯曲的过程中，所述柔性屏30的外层受拉伸，所述柔性屏30的内层受挤压，在其断面上有一个不受拉伸，又不受挤压或受到拉伸或挤压的作用力相对较小的过渡层，所述过渡层的应力很少，所述过渡层即为中性层。The neutral layer means that during the bending process of the flexible screen 30, the outer layer of the flexible screen 30 is stretched, and the inner layer of the flexible screen 30 is squeezed. , The transition layer that is not squeezed or subjected to a relatively small force of stretching or squeezing, the transition layer has very little stress, and the transition layer is a neutral layer.
各虚拟轴通过相应的结构定义。具体地，虚拟轴A1可由收容槽2737的底部的弧面的轴所定义、或者是由连接块2836的底部的弧面的轴所定义；虚拟轴A2可由连接块2738的底部的圆弧形的导面的轴所定义、或者是由收容槽2767的内壁的圆弧形的导面的轴所定义。Each virtual axis is defined by the corresponding structure.

柔性屏30贴设于展开状态中各连接铰节/转动铰节/定位组件/连接机构的弧面的顶部，并与各弧面的顶部之外的其他区域隔开。通过上述虚拟轴的方案，使得柔性屏30在弯折时可以保持长度基本不变。The flexible screen 30 is attached to the top of the arc surface of each connecting hinge/rotating hinge/positioning assembly/connection mechanism in the unfolded state, and is separated from other areas except the top of each arc surface. Through the above-mentioned virtual axis solution, the flexible screen 30 can maintain its length substantially unchanged when it is bent.
由于第一安装件281的滑槽2816的内表面开设有圆弧形的收纳槽2817及第二安装件285的滑槽2856的内表面开设有圆弧形的收纳槽2857，铰链装置24在弯折或展平的过程中，两个连杆2611的导柱2616能分别在收纳槽2817、2857内滑动，从而能减少滑槽2816、2856的开口厚度，进而能减少第一安装件281及第二安装件285的厚度，以便于减少整个电子装置100的厚度。Since the inner surface of the sliding groove 2816 of the first mounting member 281 is provided with an arc-shaped receiving groove 2817 and the inner surface of the sliding groove 2856 of the second mounting member 285 is provided with an arc-shaped receiving groove 2857, the hinge device 24 is bent During the folding or flattening process, the guide posts 2616 of the two connecting rods 2611 can slide in the receiving grooves 2817 and 2857 respectively, thereby reducing the thickness of the opening of the sliding grooves 2816 and 2856, thereby reducing the first mounting member 281 and the second The thickness of the second mounting member 285 is so as to reduce the thickness of the entire electronic device 100.
由于采用直齿条加直齿轮啮合的方式联动，相比于采用斜齿轮啮合联动的方式而言，不需要很高的制造精度，可有效地降低生产成本，提升生产效率。Due to the use of a straight rack and a spur gear meshing method, compared with a helical gear meshing method, high manufacturing accuracy is not required, which can effectively reduce production costs and improve production efficiency.
可以理解地，每个第一齿轮组件266及第二齿轮组件267内的直齿条也可以采用斜齿轮或直齿轮代替，直齿轮也可以采用斜齿轮代替，或者每个齿轮组内可以省略直齿条，直接通过二直齿轮啮合，同样可起到联动的目的。It is understandable that the straight racks in each of the first gear assembly 266 and the second gear assembly 267 can also be replaced by helical gears or spur gears, spur gears can also be replaced by helical gears, or the straight racks in each gear set can be omitted. The rack, directly meshed with two spur gears, can also serve the purpose of linkage.

When the electronic device 100 is bent, a bending force is applied to at least one of the first frame 21 and the second frame 23 of the electronic device 100 to connect to the first frame 21 The connecting links 251 on the second frame body 23 and the second frame body 23 rotate in the mutually adjacent direction, and the first positioning component 28a and the corresponding second positioning component 28b rotate in the mutually adjacent direction. Specifically, if a bending force is applied to the first frame 21, the first frame 21 drives the corresponding connecting hinge 251 and the first positioning assembly 28a at both ends of the connecting hinge 251 relative to the rotating hinge 253. The first virtual axis A1 rotates toward the side away from the flexible screen 30; the two first positioning components 28a drive the first gears 2661 of the two connecting rod members 261 to rotate along the corresponding second gears 2663 respectively. The fixing block 2621 and the second connecting shaft 2620 are relatively fixed, and the second gear 2663 is fixed on the fixing block 2621. Therefore, the second gear 2663 and the second connecting shaft 2620 are both fixed and will not rotate. The first gear 2661 can only Rotate the corresponding second gear 2663 toward the side away from the flexible screen 30, so that the connecting rod 261 rotates along the second gear 2663 toward the side away from the flexible screen 30. The connecting rod 2611 and the guide post 2616 of the connecting rod 261 are in the corresponding position. The first mounting member 281 slides in the sliding groove 2816 and the receiving groove 2817; at the same time, the connecting rod member 261 also drives the corresponding two transmission members 264 and the corresponding damping member 268 along the corresponding second connecting shaft 2620 toward and away from the flexible screen Turning on one side of 30, the transmission posts 2644 of the two transmission members 264 slide in the corresponding toggle grooves 2726 and 2786 respectively to drive the first transmission component 271 and the corresponding third transmission component 277 along the second virtual axis A2 rotates towards the side away from the flexible screen 30, the first transmission assembly 271 drives the corresponding rotating hinge 253 to rotate along the second virtual axis A2 towards the side away from the flexible screen 30; the two transmission members 264 The second gear assembly 267 drives the other two transmission members 264 to rotate along the corresponding second connecting shaft 2620 toward the side away from the flexible screen 30, and the other two transmission members 264 drive the other connecting rod 261 and the other A damping member 268 rotates toward the side away from the flexible screen 30. Since the fixing block 2621 of the fixing member 262 is relatively fixed with the second connecting shaft 2620, and the second gear 2663 is fixed on the fixing block 2621, the second gear 2663 is fixed and does not rotate. The first gear 2661 of the other connecting rod 261 can only rotate around the corresponding second gear 2663 to the side away from the flexible screen 30, so that the connecting rod of the other connecting rod 261 2611 rotates along the second gear 2663 toward the side away from the flexible screen 30; the connecting rod 2611 and the guide post 2616 of the other connecting rod 261 slidably push against the sliding groove 2856 and the receiving groove 2857 of the corresponding second mounting part 285 The second positioning component 28b and the second frame body 23 are rotated along the corresponding first virtual axis toward the side of A1 away from the flexible screen 30; at the same time, the transmission columns 2644 of the other two transmission members 264 are respectively in the corresponding toggle Sliding in the grooves 2756 and 2786 to drive the second transmission component 274 and the corresponding third transmission component 277 to rotate toward the side away from the flexible screen 30, and the second transmission component 274 drives the corresponding rotation The hinge 253 rotates along the second virtual axis A2 toward the side away from the flexible screen 30. The bendable area 31 of the flexible screen 30 is bent with the hinge device 24 until the back of the first frame 21 and the second frame 23 are attached.
此时，铰链装置24完成弯折，柔性屏30随铰链装置24实现弯折，使连接铰节251的正面、转动铰节253的正面、第一传动组件271的正面、第二传动组件274的正面及第三传动组件277的正面相互连接形成拱形的弧面，以方便贴合柔性屏30。如图27所示，弯折状态的铰链主体25的连接铰节251相背的两个侧面之间的沿铰链主体25弯折外侧的距离也为L，即铰链主体25的两个连接铰节251位于弯折外侧的两个侧面之间在展平时的直线距离与在折叠时的沿铰链主体25弯折外侧的距离相等，从而使覆盖于铰链主体25上的柔性屏30的可折弯区域31在弯折状态的宽度与展平状态的宽度相同，能防止柔性屏30被挤压凸起或拉伸使屏幕损坏。铰链主体25在弯折状态时，第一虚拟轴A1及第二虚拟轴A2均位于铰链主体25的外部，优选的，第一虚拟轴A1及第二虚拟轴A2位于覆盖在铰链主体25上的柔性屏30的中性层上。本发明中的铰链主体25的第一虚拟轴A1及第二虚拟轴A2在电子装置100折弯或展平时均位于所述中性层上，从而能保证柔性屏30最大程度不受损。At this time, the hinge device 24 is bent, and the flexible screen 30 is bent along with the hinge device 24 to connect the front of the hinge 251, the front of the rotating hinge 253, the front of the first transmission assembly 271, and the front of the second transmission assembly 274. The front surface and the front surface of the third transmission assembly 277 are connected to each other to form an arcuate surface to facilitate the fitting of the flexible screen 30. As shown in FIG. 27, the distance between the two opposite sides of the hinge body 25 of the hinge body 25 opposite to the outer side of the hinge body 25 is also L, that is, the two connecting hinges of the hinge body 25 251 The straight line distance between the two sides located on the outer side of the bend when flattened is equal to the distance from the outer side of the hinge body 25 when folded, so that the bendable area of the flexible screen 30 covering the hinge body 25 The width of 31 in the bent state is the same as the width in the flat state, which can prevent the flexible screen 30 from being squeezed, raised or stretched to damage the screen. When the hinge body 25 is in the bent state, the first virtual axis A1 and the second virtual axis A2 are both located outside the hinge body 25. Preferably, the first virtual axis A1 and the second virtual axis A2 are located on the hinge body 25. On the neutral layer of the flexible screen 30. The first virtual axis A1 and the second virtual axis A2 of the hinge body 25 of the present invention are both located on the neutral layer when the electronic device 100 is bent or flattened, so as to ensure that the flexible screen 30 is not damaged to the greatest extent.
在铰链装置24的弯折过程中，两个第一连接轴2610分别在两个阻尼件268的阻尼孔2683内转动，每一阻尼件268远离对应的第一连接轴2610的弹性挡圈2684转动地套接于对应的第二连接轴2610上，由于第一连接轴2610及第二连接轴2620分别过盈配合地插接于对应的阻尼件268，因此，铰链装置24能在弯折过程中定位于任意一角度，铰链主体25在弯折至任意角度的两个连接铰节251相背的两个侧面之间的距离不会改变，即柔性屏30的可折弯区域31在弯折至任意角度的宽度不会改变，防止柔性屏30在弯折或展平的过程中柔性屏30凸起或拉伸使屏幕损坏，能保证柔性屏30最大程度不受损。During the bending process of the hinge device 24, the two first connecting shafts 2610 respectively rotate in the damping holes 2683 of the two damping members 268, and each damping member 268 rotates away from the circlip 2684 of the corresponding first connecting shaft 2610 The ground is sleeved on the corresponding second connecting shaft 2610.
