[0031] The following will clearly and completely describe the technical solutions in the embodiments of the present application in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only some embodiments of the present application, rather than all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative efforts belong to the scope of protection of the present application.

[0032] The embodiment of the present application provides a rotating mechanism for a foldable display terminal to solve the problem that the rotating mechanism is prone to breakage and deformation at the connection, thus affecting the stability of the rotating mechanism. The following will be described in conjunction with the accompanying drawings.

[0033] The rotation mechanism of the foldable display terminal provided by the embodiment of the present application can be used in a display terminal. The display terminal includes a first display part and a second display part. The first display part is connected to the second display part through the rotation mechanism. Specifically, the first display part and the second display part of the display terminal are respectively installed on two rotating members 200, and the two rotating members 200 are respectively rotatably connected to the connecting member 100, so as to realize the folding and unfolding of the display terminal. The display terminal can be any terminal with a display function such as a mobile phone, an electronic paper, a display, a notebook computer, a navigator, etc.

[0034] In order to more clearly illustrate the structure of the rotation mechanism of the foldable display terminal, the rotation mechanism of the foldable display terminal will be introduced below with reference to the accompanying drawings.

[0035] Exemplarily, please refer to Figures 1 to 6 , Figure 1 which is a schematic structural diagram of the rotation mechanism of the foldable display terminal provided by the embodiment of the present application. Figure 2 For Figure 1 the exploded structural diagram of a perspective view of the rotation mechanism of the foldable display terminal shown. Figure 3 For Figure 1 the exploded structural diagram of another perspective view of the rotation mechanism of the foldable display terminal shown. Figure 4 which is a schematic structural diagram of the rotation mechanism of the foldable display terminal provided by the embodiment of the present application in the unfolded state. Figure 5 For Figure 4 the sectional view of the rotation mechanism of the foldable display terminal shown along the A-A direction. Figure 6This is a schematic structural diagram of the rotating mechanism of the foldable display terminal provided by the embodiment of the present application in the folded state. The rotating mechanism of the foldable display terminal includes a connecting member 100, a rotating member 200, and a buffer member 300. The rotating member 200 includes a supporting portion 210 and a mating portion 220. One of the mating portion 220 and the connecting member 100 is provided with a transfer rib 101, and the other is provided with a transfer groove 221. The transfer groove 221 is arranged in an arc shape, and the transfer rib 101 is movably engaged with the transfer groove 221 so that the rotating member 200 rotates along the extending direction of the transfer groove 221. The buffer member 300 is arranged between the arc wall of the transfer groove 221 and the transfer rib 101. Among them, the transfer rib 101 is movably engaged with the transfer groove 221, so that the transfer rib 101 can rotate relative to the transfer groove 221. For example, the transfer rib 101 can rotate along the extending direction of the transfer groove 221, or the transfer groove 221 can rotate along the direction of the transfer rib 101, etc. As long as the rotating member 200 can finally rotate along the extending direction of the transfer groove 221, it can realize that the rotating member 200 can rotate relative to the connecting member 100 while making the rotating member 200 rotate along a preset track. In the embodiment of the present application, the buffer member 300 is arranged between the arc wall of the transfer rib 101 and the transfer groove 221. On the one hand, the buffer member 300 can play a role in absorbing external forces, so that during the rotation of the rotating member 200, the buffer member 300 can absorb the acting force generated by the arc wall of the transfer rib 101 and the transfer groove 221, effectively preventing the adverse conditions such as the fracture and deformation of the rotating member 200 or the connecting member 100 caused by the excessive mutual acting force between the arc wall of the transfer rib 101 and the transfer groove 221, and ensuring the stability and reliability of the rotating mechanism. On the other hand, the buffer member 300 can fill the gap between the transfer rib 101 and the transfer groove 221, so that the rotating member 200 rotates along a preset track, ensuring the use effect of the rotating mechanism, thereby improving the stability and reliability of the display terminal.

[0036] In practical applications, the number of the rotating members 200 is two. The two rotating members 200 are arranged oppositely and are respectively rotatably connected to the connecting member 100, so that the supporting portions 210 of the two rotating members 200 have a folded state of approaching each other and an unfolded state of moving away from each other. That is to say, by rotating the two rotating members 200, the two rotating members 200 approach or move away from each other, so as to realize that the casing of the display terminal is in a folded or unfolded state, and realize the foldability of the display terminal.

[0037] Regarding the buffer member 300, please continue to refer to Figure 7 , Figure 7A schematic diagram of the structure of the buffer 300 of the rotating mechanism of the foldable display terminal provided in the embodiment of the present application. In one embodiment, the buffer 300 includes a connecting portion 310 and a buffer portion 320 located on the side of the connecting portion 310, the connecting portion 310 is connected to the transfer rib 101, and the buffer portion 320 abuts against the arc wall of the transfer groove 221. The connecting portion 310 is used to connect with the transfer rib 101, and there are many ways to connect it, such as spot welding, interference fit, bonding, and clamping, to ensure the stability of the connection between the buffer 300 and the transfer rib 101. Specifically, the connecting portion 310 is sleeved on one end of the transfer rib 101 close to the bottom of the transfer groove 221, so that the contact area between the connecting portion 310 and the transfer rib 101 is increased, thereby effectively ensuring the stability of the connection between the two.

[0038] The buffer portion 320 abuts against the arc wall of the transfer groove 221. Specifically, there are two buffer portions 320, which are arranged on opposite sides of the connecting portion 310, and the two buffer portions 320 respectively abut against the convex arc wall 222 and the concave arc wall 223 of the transfer groove 221. The buffer portion 320 is bent and has at least one bent portion 321, for example, two bent portions 321, so that the buffer portion 320 has space for elastic deformation, and can convert external force into kinetic energy to absorb the force from the rotating member 200 and the connecting member 100, and prevent the force from being concentrated on the transfer rib 101 or the arc wall of the transfer groove 221, thereby effectively preventing the rotating member 200 and the connecting member 100 from being broken or deformed.

[0039] Regarding the material of the buffer 300, a wear-resistant material can be selected, such as a metal material, for example, stainless steel, aluminum, etc. Since the buffer 300 is arranged between the transfer rib 101 and the transfer groove 221, the buffer 300 will often generate friction with the groove wall of the transfer groove 221 during the operation of the rotating member 200. The use of wear-resistant materials for the buffer 300 is conducive to ensuring the wear resistance of the buffer 300, thereby improving the service life of the buffer 300. The buffer 300 is made of metal material, which takes advantage of the high strength of the metal material, so that the buffer 300 is not easy to be damaged and broken, and the reliability of the use of the buffer 300 is ensured.

[0040] In some embodiments, to improve the buffering effect of the buffer member 300, the buffer member 300 has a buffering arc surface 322, and the buffering arc surface 322 abuts against the arc wall surface of the transfer rib 101. Combining with the embodiment in which the two buffer portions 320 respectively abut against the convex arc wall 222 and the concave arc wall 223 of the transfer groove 221, one of the two buffer portions 320 has a buffering convex arc surface, and the other has a buffering concave arc surface. The buffering convex arc surface abuts against the convex arc wall 222 of the transfer groove 221, and the buffering concave arc surface abuts against the concave arc wall 223 of the transfer groove 221, so as to increase the contact area between the buffer member 300 and the transfer rib 101, improve the effect of the buffer member 300 absorbing external forces, and improve the use effect of the buffer member 300.

[0041] In some embodiments, the extending direction of the buffer member 300 is the same as that of the transfer groove 221. In this way, it is beneficial to improve the compactness between the buffer member 300 and the transfer groove 221. On the one hand, it ensures that the buffer member 300 can effectively absorb the acting forces of the arc walls of the transfer rib 101 and the transfer groove 221, so as to effectively prevent the occurrence of adverse conditions such as fracture and deformation of the rotating member 200 or the connecting member 100 due to excessive mutual acting forces between the arc walls of the transfer rib 101 and the transfer groove 221, and ensures the stability and reliability of the rotating structure. On the other hand, it ensures that the buffer member 300 fills the gap between the transfer rib 101 and the transfer groove 221, so that the rotating member 200 rotates along the preset trajectory, ensuring the use effect of the rotating structure, and thus improving the stability and reliability of the display terminal. Further, the extending direction of the transfer rib 101 is the same as that of the transfer groove 221, and the lengths of the transfer rib 101 and the buffer member 300 are equivalent. In this way, it is beneficial to improve the matching degree between the transfer rib 101 and the transfer groove 221, and to ensure to a greater extent that the rotating member 200 rotates along the preset trajectory. The equivalent lengths of the transfer rib 101 and the buffer member 300 are also beneficial to increase the contact area between the transfer rib 101 and the buffer member 300, so as to improve the connection stability between the two, and thus improve the stability and reliability of the rotating mechanism. In some embodiments, there is a clearance gap 103 between the buffer member 300 and the bottom of the transfer groove 221. This can avoid the buffer member 300 hindering the movable cooperation between the transfer rib 101 and the transfer groove 221.

[0042] Regarding the setting method and setting position of the transfer rib 101 and the transfer groove 221, there are many choices. It is possible to set the transfer groove 221 on the connecting member 100 and set the transfer rib 101 on the rotating member 200, or it is also possible to set the transfer rib 101 on the connecting member 100 and set the transfer groove 221 on the rotating member 200. Here is an example for illustration.

[0043] In some embodiments, the connecting member 100 is provided with an avoidance groove 102. A transfer rib 101 extends inwards from the side groove wall of the avoidance groove 102, and a transfer groove 221 is provided on the side wall of the fitting portion 220. In this embodiment, the avoidance groove 102 can provide a movement space for the rotating member 200 to rotate, avoiding collision between the rotating member 200 and the connecting member 100 during rotation. In specific applications, the number of transfer ribs 101 is two, which are respectively arranged on the opposite two groove walls of the avoidance groove 102, and the number and position of the transfer grooves 221 correspond to the number and position of the transfer ribs 101. In this way, both sides of the rotating member 200 are rotationally engaged with the connecting member 100, enabling balanced force on both sides of the rotating member 200, improving the balance of the rotating member 200, and ensuring the stability and reliability of the rotating mechanism.
