现结合图4～图13对铰链机构的细节结构进行说明。The detailed structure of the hinge mechanism will now be described with reference to FIGS. 4 to 13 .

如图4～图6所示，铰链机构包括齿轮组件200和两组转板组件100。其中一组转板组件100的一端与第一外壳组件400连接，另一组转板组件100的一端与第二外壳组件500连接，转板组件100包括转动板110和转轴板120，转轴板120的一端与转动板110可转动连接，齿轮组件200与转轴板120背离转动板110的一端啮合，使转轴板120既起到连接的作用，又起到与齿轮组件200啮合，驱动齿轮组件200运动，集成多个结构效果，有效降低组装误差和加工成本。在齿轮组件200与转板组件100的作用下，能够实现移动终端的同步联动转动，以减小可折叠的移动终端在转动过程中对柔性屏700体的挤压力，降低柔性面板受损风险，从而提高柔性面板及移动终端的使用寿命，进而能够满足不同用户对铰链机构区域贴屏平整性的要求。As shown in FIGS. 4 to 6 , the hinge mechanism includes agear assembly 200 and two sets ofrotating plate assemblies 100 . One end of one set of rotatingplate assemblies 100 is connected to thefirst housing assembly 400, and one end of the other group of rotatingplate assemblies 100 is connected to thesecond housing assembly 500. Therotating plate assembly 100 includes arotating plate 110 and arotating shaft plate 120. Therotating shaft plate 120 One end of therotating plate 110 is rotatably connected, and thegear assembly 200 meshes with the end of therotating shaft plate 120 away from therotating plate 110, so that therotating shaft plate 120 not only plays the role of connection, but also plays the role of meshing with thegear assembly 200, driving thegear assembly 200 to move , integrating multiple structural effects, effectively reducing assembly errors and processing costs. Under the action of thegear assembly 200 and therotating plate assembly 100, the synchronous linkage rotation of the mobile terminal can be realized, so as to reduce the extrusion force of the foldable mobile terminal on theflexible screen 700 during the rotation process, and reduce the risk of damage to the flexible panel , so as to improve the service life of the flexible panel and the mobile terminal, thereby meeting the requirements of different users on the flatness of the screen in the hinge mechanism area.

When thefirst shell assembly 400 and thesecond shell assembly 500 are folded toward each other, the tworotating plates 110 and thecentral plate 300 form an isosceles triangle. Under the action of thegear assembly 200 and therotating plate assembly 100, the The synchronous linkage rotation of the mobile terminal is to reduce the extrusion force of the foldable mobile terminal on theflexible screen 700 during the rotation process, reduce the probability of damage to the flexible panel, thereby improving the service life of the flexible panel and the mobile terminal, thereby meeting Different users have requirements for the flatness of the screen in the hinge mechanism area.

如图11所示，当移动终端处于展平状态时，转轴板120的连接销122位于第一滑槽114与第二滑槽131靠近第一外壳组件400或第二外壳组件500的一端，第一滑槽114与第二滑槽131成10°的夹角。当用户给予第一外壳组件400或第二外壳组件500转动力时，移动终端第一外壳组件400和第二外壳组件500分别围绕齿轮组件200的第一齿轮123的中心旋转，转轴板120的连接销122分别在第一滑槽114与第二滑槽131里做直线运动，转动板110与连接板130围绕旋转轴113的中心做旋转运动，转板组件100绕连接槽211的中心做旋转运动。当移动终端处于折叠状态时，转轴板120的连接销122位于第一滑槽114与第二滑槽131中靠近齿轮组件200的一端，第一滑槽114与第二滑槽131成2°的夹角，两个转动板110形成约16°的等腰三角形空间，柔性屏700也形成了16°的水滴状形状，避免对柔性屏700造成挤压。As shown in FIG. 11 , when the mobile terminal is in the flattened state, the connectingpin 122 of thehinge plate 120 is located at one end of thefirst chute 114 and thesecond chute 131 close to thefirst shell component 400 or thesecond shell component 500 , the second The angle between the first slidingslot 114 and the second slidingslot 131 is 10°.

For the included angle, the tworotating plates 110 form an isosceles triangle space of about 16°, and theflexible screen 700 also forms a drop-like shape of 16° to avoid squeezing theflexible screen 700 .

如图5和图8和图12所示，齿轮组件200还包括支撑底座220、齿轮组230以及多个齿轮轴240，齿轮组230的两端分别与两个转轴板120啮合，即对称设置在齿轮组件200两侧的两个转轴板120的两个第一齿轮123啮合，多个齿轮轴240分别穿过齿轮组230以及两个转轴板120，支撑底座220为两个，齿轮轴240的两端分别与设置在两端的支撑底座220可转动连接，以便于转动板110转动时带动转轴板120转动，进而通过转轴板120的第一齿轮123驱动齿轮组230转动。且支撑底座220具有支撑和固定作用。进一步地，齿轮组230包括两个平行且相互啮合设置的第二齿轮231，齿轮轴240包括四个，四个齿轮轴240分别穿过两个第一齿轮123和两个第二齿轮231设置。5, 8 and 12, thegear assembly 200 also includes asupport base 220, agear set 230, and a plurality ofgear shafts 240. The twofirst gears 123 of the tworotating shaft plates 120 on both sides of thegear assembly 200 mesh, a plurality ofgear shafts 240 pass through the gear set 230 and the tworotating shaft plates 120 respectively, there are two supportingbases 220, and the twogear shafts 240 The ends are respectively rotatably connected to the support bases 220 arranged at both ends, so that when therotating plate 110 rotates, the rotatingshaft plate 120 is driven to rotate, and then thefirst gear 123 of therotating shaft plate 120 drives the gear set 230 to rotate. And the supportingbase 220 has the function of supporting and fixing. Further, the gear set 230 includes twosecond gears 231 arranged in parallel and meshing with each other, and thegear shafts 240 include four, and the fourgear shafts 240 are respectively arranged through the twofirst gears 123 and the twosecond gears 231 .

如图5和图8和图12所示，齿轮组件200还包括固定凸轮260、移动凸轮250以及多个复位件270。其中，移动凸轮250套设在四个齿轮轴240，移动凸轮250能够在四个齿轮轴240上沿齿轮轴240的轴线方向移动，但不能转动。固定凸轮260套设在齿轮轴240上，且固定凸轮260设置在齿轮组230背离支撑底座220的一侧，固定凸轮260与齿轮组230以及两个转动板110连接，固定凸轮260能够驱动移动凸轮250沿齿轮轴240的轴线方向移动，复位件270套设在齿轮轴240上，且复位件270设置在支撑底座220和移动凸轮250之间，移动凸轮250、齿轮轴240、复位件270主要起阻尼作用，实现第一外壳组件400和第二外壳组件500折叠过程中能够在任意位置停留。具体而言，复位件270优选为弹簧，弹簧属于常规零件，便于采购，且使用寿命长，成本低。可以理解的是，复位件270为四个，与齿轮轴240的数量对应设置。As shown in FIG. 5 , FIG. 8 and FIG. 12 , thegear assembly 200 further includes a fixedcam 260 , a movingcam 250 and a plurality ofreset members 270 . Wherein, the movingcam 250 is sleeved on the fourgear shafts 240 , and the movingcam 250 can move along the axial direction of thegear shafts 240 on the fourgear shafts 240 , but cannot rotate. The fixedcam 260 is sleeved on thegear shaft 240, and the fixedcam 260 is arranged on the side of the gear set 230 away from thesupport base 220. The fixedcam 260 is connected with the gear set 230 and the tworotating plates 110. The fixedcam 260 can drive the movingcam 250 moves along the axial direction of thegear shaft 240, thereset member 270 is sleeved on thegear shaft 240, and thereset member 270 is arranged between thesupport base 220 and the movingcam 250, the movingcam 250, thegear shaft 240, and thereset member 270 mainly act The damping effect enables thefirst shell assembly 400 and thesecond shell assembly 500 to stay at any position during the folding process. Specifically, thereset member 270 is preferably a spring, and the spring is a conventional part, which is easy to purchase, has a long service life, and is low in cost. It can be understood that there are fourreset members 270 , corresponding to the number ofgear shafts 240 .

如图12所示，固定凸轮260上开设有多个凹陷部261，凹陷部261设置在背离齿轮组230的一端，且凹陷部261沿固定凸轮260周向间隔设置，移动凸轮250包括凸轮本体251和多个凸轮部252，凸轮本体251天设在齿轮轴240上，且凸轮部252沿凸轮本体251向远离凸轮本体251的方向延伸，多个凸轮部252与多个凹陷部261一一配合设置。工作时，第一齿轮123驱动第二齿轮231转动，进而带动与第一齿轮123和第二齿轮231连接的固定凸轮260转动，由于固定凸轮260与移动凸轮250通过凹陷部261与凸轮部252相配合设置，固定凸轮260转动时，凹陷部261随之转动，而移动凸轮250在转动方向的自由度被约束时，凹陷部261的侧壁驱动凸轮部252向滑出凹陷部261的方向运动，即使移动凸轮250向远离固定凸轮260方向运动，当固定凸轮260转动至下一个凹陷部261与凸轮部252相对应时，在复位件270的推力作用下，凸轮部252再次向固定凸轮260运动，使凸轮部252滑入凹陷部261，此时第一外壳组件400和第二外壳组件500的相对位置锁定，从而实现第一外壳组件400和第二外壳组件500折叠过程中能够在任意位置停留。As shown in FIG. 12 , the fixedcam 260 is provided with a plurality ofrecesses 261 , therecesses 261 are arranged at one end away from the gear set 230 , and therecesses 261 are arranged at intervals along the circumference of the fixedcam 260 , and the movingcam 250 includes acam body 251 And a plurality ofcam parts 252, thecam body 251 is arranged on thegear shaft 240, and thecam part 252 extends along thecam body 251 to the direction away from thecam body 251, and the plurality ofcam parts 252 and the plurality of recessedparts 261 are arranged one by one . During work, thefirst gear 123 drives thesecond gear 231 to rotate, and then drives the fixedcam 260 connected with thefirst gear 123 and thesecond gear 231 to rotate, because the fixedcam 260 and the movingcam 250 are in contact with thecam part 252 through theconcave part 261 Cooperate with the arrangement, when the fixedcam 260 rotates, theconcave portion 261 rotates accordingly, and when the degree of freedom of the movingcam 250 in the rotation direction is constrained, the side wall of theconcave portion 261 drives thecam portion 252 to slide out of theconcave portion 261. Even if themovable cam 250 moves away from the fixedcam 260, when the fixedcam 260 rotates until the nextconcave portion 261 corresponds to thecam portion 252, under the thrust of thereset member 270, thecam portion 252 moves toward the fixedcam 260 again, Thecam part 252 is slid into the recessedpart 261, and at this moment the relative positions of thefirst shell component 400 and thesecond shell component 500 are locked, so that thefirst shell component 400 and thesecond shell component 500 can stay in any position during the folding process.

由此可见，四个固定凸轮260主要是传递移动终端转动扭矩的作用，当旋转第一外壳组件400时，同步将旋转扭矩传递到移动终端的第二外壳组件500上，或者当旋转第二外壳组件500时，同步将旋转扭矩传递到移动终端的第一外壳组件400上，实现移动终端的第一外壳组件400和第二外壳组件500同时展平与折叠。It can be seen that the fourfixed cams 260 are mainly used to transmit the rotational torque of the mobile terminal. When thefirst housing assembly 400 is rotated, the rotational torque is transmitted to thesecond housing assembly 500 of the mobile terminal synchronously, or when thesecond housing assembly 400 is rotated When theassembly 500 is used, the rotational torque is transmitted to thefirst casing assembly 400 of the mobile terminal synchronously, so that thefirst casing assembly 400 and thesecond casing assembly 500 of the mobile terminal are simultaneously flattened and folded.

可以理解的是，为了提高铰链机构运动的稳定性，齿轮组件200为两组，两组齿轮组件200沿转动板110的长度方向设置，以保证设置在齿轮组件200两侧的转板组件100的转动力能够在齿轮组件200中稳定传递，提高移动终端的第一外壳组件400和第二外壳组件500展平或折叠运动的稳定性。It can be understood that, in order to improve the stability of the movement of the hinge mechanism, thegear assembly 200 is divided into two groups. The rotational force can be stably transmitted in thegear assembly 200, improving the stability of the flattening or folding movement of thefirst shell assembly 400 and thesecond shell assembly 500 of the mobile terminal.

现结合图1～图13对移动终端的工作过程进行介绍：The working process of the mobile terminal is now introduced in conjunction with Figures 1 to 13:

如图1～图13所示，当移动终端处于展平状态时，转轴板120的连接销122位于第一滑槽114与第二滑槽131靠近第一外壳组件400或第二外壳组件500的一端，第一滑槽114与第二滑槽131成10°的夹角。As shown in FIGS. 1 to 13 , when the mobile terminal is in the flattened state, the connectingpin 122 of thehinge plate 120 is located between thefirst chute 114 and thesecond chute 131 close to thefirst housing assembly 400 or thesecond housing assembly 500 . At one end, thefirst chute 114 and thesecond chute 131 form an angle of 10°.

当需要折叠移动终端时，用户给予第一外壳组件400或第二外壳组件500转动力时，转动板110能够带动转轴板本体121转动，移动终端的第一外壳组件400和第二外壳组件500分别围绕齿轮组件200的第一齿轮123的中心旋转，转轴板120的连接销122分别在第一滑槽114与第二滑槽131里做直线运动，转动板110与连接板130围绕旋转轴113的中心做旋转运动，转板组件100围绕连接槽211的中心做旋转运动。第一齿轮123与第二齿轮231在啮合作用下转动，以带动固定凸轮260转动。固定凸轮260的凹陷部261能够驱动移动凸轮250向远离固定凸轮260的方向运动，此时，复位件270受到压缩。随着转轴板120的转动，当移动凸轮250的凸轮部252与下一个凹槽部相配合时，复位件270能够驱动移动凸轮250向靠近固定凸轮260方向运动，然后滑入相应的凹槽部中，此时，第一外壳组件400和第二外壳组件500的相对位置固定。When the mobile terminal needs to be folded, when the user gives thefirst shell assembly 400 or the second shell assembly 500 a rotating force, therotating plate 110 can drive thehinge plate body 121 to rotate, and thefirst shell assembly 400 and thesecond shell assembly 500 of the mobile terminal are respectively Rotate around the center of thefirst gear 123 of thegear assembly 200, the connectingpin 122 of therotating shaft plate 120 makes a linear motion in thefirst chute 114 and thesecond chute 131 respectively, and therotating plate 110 and the connectingplate 130 rotate around therotating shaft 113 The center rotates, and therotating plate assembly 100 rotates around the center of the connectinggroove 211 . Thefirst gear 123 and thesecond gear 231 rotate under meshing action to drive the fixedcam 260 to rotate. Theconcave portion 261 of the fixedcam 260 can drive the movingcam 250 to move away from the fixedcam 260 , and at this time, thereset member 270 is compressed. With the rotation of therotating shaft plate 120, when thecam portion 252 of the movingcam 250 matches the next groove portion, thereset member 270 can drive the movingcam 250 to move toward the fixedcam 260, and then slide into the corresponding groove portion In this case, the relative positions of thefirst housing component 400 and thesecond housing component 500 are fixed.

用户继续驱动第一外壳组件400和第二外壳组件500相互靠近，移动终端处于折叠状态，如图13所示，第一外壳组件400和第二外壳组件500局部重叠，转轴板120的连接销122位于第一滑槽114与第二滑槽131中靠近齿轮组件200的端，第一滑槽114与第二滑槽131成2°的夹角，两个转动板110形成约16°的等腰三角形空间，柔性屏700也形成了16°的水滴状形状。The user continues to drive thefirst housing assembly 400 and thesecond housing assembly 500 close to each other, and the mobile terminal is in a folded state. As shown in FIG.
