[0054] refer to Figure 1 and Figure 2 In one embodiment, the foldable mobile terminal 10 is a smart phone. The foldable mobile terminal 10 includes a flexible screen 100, a housing assembly 200 and a folding mechanism 300. The flexible screen 100 has a bendable property, and the flexible screen 100 can display information and provide an interactive interface for the user. The housing assembly 200 includes a first housing 210 and a second housing 220, and the flexible screen 100 is covered on the first housing 210 and the second housing 220 and connected to the first housing 210 and the second housing 220 respectively. Figure 3 The folding mechanism 300 includes a first damping component 310, a second damping component 320 and a connecting member 330. The connecting member 330 is connected to the first damping component 310 and the second damping component 320 respectively. The first damping component 310 is connected to the first housing 210, and the second damping component 320 is connected to the second housing 220. The first housing 210 can be rotated relative to the second housing 220 through the folding mechanism 300 to realize the unfolding and folding of the foldable mobile terminal 10. Figure 4 , the housing assembly 200 of the foldable mobile terminal 10 is in an unfolded state.

[0055] refer to Figure 3 In one embodiment, the connecting member 330 is provided with a first mounting hole 331, a second mounting hole 333 and a mounting groove 335, the first mounting hole 331 and the second mounting hole 333 are respectively connected to the mounting groove 335, the first damping assembly 310 is inserted into the first mounting hole 331, the connecting rod 316 of the first damping assembly 310 protrudes from the first mounting hole 331 and is fixedly connected to the first housing 210, the second damping assembly 320 is inserted into the second mounting hole 333, the second damping assembly 320 protrudes from the second mounting hole 333 and is fixedly connected to the second housing 220. Further, the foldable mobile terminal 10 includes a cover plate 340 covering the mounting groove 335, the cover plate 340 is used to limit the position of the first damping assembly 310 in the first mounting hole 331 to prevent the first damping assembly 310 from coming out of the first mounting hole 331. Likewise, the cover plate 340 can limit the position of the second damping assembly 320 in the second mounting hole 333 to prevent the second damping assembly 320 from escaping from the second mounting hole 333 .

[0056] In one embodiment, the flexible screen 100 is covered on the side where the cover plate 340 is located, and when the foldable mobile terminal 10 is folded, the displayable area of ​​the flexible screen 100 is exposed to the housing assembly 200. When the foldable mobile terminal 10 is in the folded state, the flexible screen 100 is exposed to the housing assembly 200, and when in the folded state, the user can use the foldable mobile terminal 10 normally.

[0057] refer to Figure 5 and Figure 6 , the housing assembly 200 is in a closed state. During the rotation of the first housing 210 relative to the second housing 220, the first housing 210 and the second housing 220 can respectively drive the flexible screen 100 to rotate and bend the flexible screen 100. During the unfolding and folding of the foldable mobile terminal 10, the first housing 210 rotates relative to the connecting member 330 through the first damping assembly 310, and the second housing 220 rotates relative to the connecting member 330 through the second damping assembly 320, and the rotation damping of the first damping assembly 310 is greater than the rotation damping of the second damping assembly 320.

[0058] It is understood that rotational damping refers to the magnitude of the rotational resistance during the rotation process, and rotational damping represents the magnitude of the rotational torque generated by the resistance during the rotation process that hinders the rotation. It is understood that rotational damping can be continuous. For example, in this embodiment, when the first shell 210 rotates relative to the connecting member 330, the rotational damping of the first damping assembly 310 changes continuously, and the rotational damping hinders the rotation of the first shell 210 relative to the connecting member 330. When the second shell 220 rotates relative to the connecting member 330, the rotational damping of the second damping assembly 320 changes continuously, and the rotational damping hinders the rotation of the second shell 220 relative to the connecting member 330. However, rotational damping can provide clear tactile feedback to the user, and rotational damping can also be used for positioning the first shell 210 and the second shell 220 relative to the connecting member 330. For example, in one embodiment, the foldable mobile terminal 10 adopts the above structure, when the angle between the first shell 210 and the second shell 220 is within the range of 45 degrees to 180 degrees, the first shell 210 and the second shell 220 can be positioned at any angle within the angle range, so as to facilitate the user to use the foldable mobile terminal 10. In one embodiment, the foldable mobile terminal 10 adopts the above structure, the angle between the first shell 210 and the second shell 220 can be in multiple stable states. For example, when the angle between the first shell 210 and the second shell 220 is 90 degrees, 120 degrees, 135 degrees, etc., the first shell 210 and the second shell 220 can be in a stable positioning state, so as to facilitate the use of the user.

[0059] Specifically, refer to Figure 7 and Figure 8The first damping assembly 310 includes a housing 311, an elastic member 313, a movable block 315, a stopper 317 and a snap ring 319. The housing 311 is fixedly connected to the connecting member 330. The elastic member 313 is disposed in the housing 311, and one end of the elastic member 313 abuts against the housing 311. The movable block 315 is slidably disposed in the housing 311 and abuts against the other end of the elastic member 313 and compresses the elastic member 313. The stopper 317 includes a connecting rod 316 and a stopper 318. The connecting rod 316 can be integrally formed with the stopper 318, and the connecting rod 316 can also be detachably connected to the stopper 318 or non-detachably connected. The connecting rod 316 is roughly cylindrical, and is provided through the housing 311, the elastic member 313 and the movable block 315. One end of the connecting rod 316 protrudes from the housing 311 and is fixedly connected to the first housing 210, and the other end of the connecting rod 316 is fixedly connected to the stopper 318. The elastic member 313 presses the movable block 315 so that the movable block 315 presses the stopper 318. The snap ring 319 is clamped on the end of the connecting rod 316 protruding from the housing 311 so that the housing 311 is fixed in the axial direction of the connecting rod 316. In the process of the first housing 210 rotating relative to the connecting member 330 through the first damping assembly 310, the first housing 210 can drive the stopper 318 to rotate relative to the movable block 315 through the connecting rod 316, so that the movable block 315 slides relative to the housing 311. Since the elastic member 313 is in a compressed state and pressed against the movable block 315 , the friction force generated on the contact surface between the movable block 315 and the stopper 318 generates resistance to the rotation of the movable block 315 relative to the stopper 318 , that is, generates rotation damping.

[0060] The internal structure and principle of the second damping assembly 320 are similar to those of the first damping assembly 310, and will not be described in detail here. It is understood that when the friction moment of the movable block 315 of the first damping assembly 310 relative to the stopper 318 is greater than the friction torque in the second damping assembly 320, the rotational damping of the first damping assembly 310 is greater than the rotational damping of the second damping assembly 320. It is understood that the magnitude of the friction torque is related to the compression elastic force of the elastic member 313 and the friction factor between the movable block 315 and the stopper 318. In this embodiment, the compression elastic force of the elastic member 313 in the first damping assembly 310 is greater than the compression elastic force of the elastic member 313 in the second damping assembly 320. In one embodiment, the rotational damping of the first damping assembly 310 is 100N, and the rotational damping of the second damping assembly 320 is 30N. In one embodiment, the elastic member 313 is a spring. In other embodiments, the elastic member 313 may be a spring sheet or an elastic column, which will not be described in detail herein.

[0061] In the foldable mobile terminal 10, since the rotation damping of the first damping component 310 is greater than the rotation damping of the second damping component 320, during the unfolding and folding process of the foldable mobile terminal 10, the second damping component 320 can be unfolded or folded before the first damping component 310, and the first damping component 310 and the second damping component 320 can provide a clear hand feeling to the user to improve the user experience. The arrangement of the first damping component 310 and the second damping component 320 is also conducive to the positioning of the first shell 210 and the second shell 220 at multiple angles.

[0062] refer to Fig. 9 and Fig.10 The movable block 315 includes an integrally formed body 3151 and a first boss 3153, wherein the first boss 3153 protrudes from one end of the body 3151 facing the stopper 318. The end of the stopper 318 facing the movable block 315 is provided with a groove 3181 and a second boss 3183, and the second boss 3183 and the groove wall of the groove 3181 are smoothly transitioned through an inclined surface 3185. When the first housing 210 drives the stopper 318 to rotate relative to the movable block 315 through the connecting rod 316, the first boss 3153 can slide from the second boss 3183 into the groove 3181 and can slide out from the groove 3181 to the second boss 3183. Further, referring to Fig.11 and Fig.12 As an implementation method, during the closing process of the foldable mobile terminal 10, the elastic member 313 can press against the movable block 315, and when the first boss 3153 slides onto the inclined surface 3185, the elastic member 313 can push the first boss 3153 to quickly slide into the groove 3181. For example, in one embodiment, during the closing process of the foldable mobile terminal 10, when the angle between the first shell 210 and the second shell 220 is less than or equal to 10 degrees, the first boss 3153 slides onto the inclined surface 3185, and under the action of the elastic member 313, the first boss 3153 quickly slides into the groove 3181, and the stopper 318 drives the connecting rod 316 to rotate quickly, thereby driving the first shell 210 to close quickly, that is, the first damping assembly 310 can drive the first shell 210 and the second shell 220 to close automatically. It can be understood that the second damping assembly 320 can adopt a similar structure, which will not be repeated here. It is understandable that by changing the direction of the inclined surface 3185, the above structure can also be used to achieve rapid expansion of the first shell 210 relative to the second shell 220. The above structure is conducive to improving the user experience. It is understandable that by changing the angle of the inclined surface, the speed at which the first shell 210 and the second shell 220 are quickly closed can be changed.

[0063] In one embodiment, during the folding process of the foldable mobile terminal 10, the first housing 210 can abut against the connecting member 330 to limit the rotation range of the first housing 210 relative to the connecting member 330. Fig.13 and Fig.14 In this embodiment, the flattened state of the foldable mobile terminal 10 is used as the reference zero position of the angle. When the first shell 210 rotates 90 degrees relative to the connecting member 330, the side of the first shell 210 facing away from the flexible screen 100 abuts against the connecting member 330, and the connecting member 330 can limit the rotation of the first shell 210. Similarly, when the second shell 220 rotates 90 degrees relative to the connecting member 330, the side of the second shell 220 facing away from the flexible screen 100 can also abut against the connecting member 330 to limit the rotation range of the second shell 220. The above arrangement uses the connecting member 330 to limit the rotation range of the first shell 210 or the second shell 220, which can protect the flexible screen 100, the first damping assembly 310 and the second damping assembly 320 to prevent the flexible screen 100 from being damaged or the folding mechanism 300 from being damaged due to excessive rotation angle.

[0064] In one embodiment, a folding assembly is provided, and the folding assembly is used for a foldable mobile terminal 10, and the folding assembly includes a housing assembly 200 and a folding mechanism 300. Specifically, the housing assembly 200 includes a first housing 210 and a second housing 220. The folding mechanism 300 includes a first damping assembly 310, a second damping assembly 320 and a connecting member 330, and the connecting member 330 is connected to the first damping assembly 310 and the second damping assembly 320 respectively, the first damping assembly 310 is connected to the first housing 210, and the second damping assembly 320 is connected to the second housing 220. The first housing 210 can be rotated relative to the second housing 220 through the folding mechanism 300 to realize the unfolding and folding of the foldable mobile terminal 10. During the unfolding and folding process of the foldable mobile terminal 10, the first shell 210 rotates relative to the connecting member 330 through the first damping assembly 310, and the second shell 220 rotates relative to the connecting member 330 through the second damping assembly 320, and the rotational damping of the first damping assembly 310 is greater than the rotational damping of the second damping assembly 320.

[0065] Specifically, the first damping assembly 310 is taken as an example. The first damping assembly 310 includes a housing 311, an elastic member 313, a movable block 315, a stopper 317 and a snap ring 319. The housing 311 is fixedly connected to the connecting member 330. The elastic member 313 is arranged in the housing 311, and one end of the elastic member 313 abuts against the housing 311. The movable block 315 is slidably arranged in the housing 311 and abuts against the other end of the elastic member 313 and compresses the elastic member 313. The stopper 317 includes a connecting rod 316 and a stopper 318. The connecting rod 316 is penetrated through the housing 311, the elastic member 313 and the movable block 315, and one end of the connecting rod 316 protrudes from the housing 311 and is fixedly connected to the first housing 210, and the other end of the connecting rod 316 is fixedly connected to the stopper 318. The elastic member 313 presses the movable block 315 so that the movable block 315 presses the stopper 318. The clamping ring 319 is clamped on one end of the connecting rod 316 protruding from the housing 311. When the first housing 210 rotates relative to the connecting member 330 through the first damping assembly 310, the first housing 210 can drive the stopper 318 to rotate relative to the movable block 315 through the connecting rod 316, so that the movable block 315 slides relative to the housing 311.

[0066] When the foldable assembly is applied to the foldable mobile terminal 10, since the rotational damping of the first damping component 310 is greater than the rotational damping of the second damping component 320, during the unfolding and folding process of the foldable mobile terminal 10, the second damping component 320 can be unfolded or folded before the first damping component 310, and the first damping component 310 and the second damping component 320 can provide the user with a clear hand feeling to enhance the user experience. The arrangement of the first damping component 310 and the second damping component 320 is also conducive to the positioning of the first shell 210 and the second shell 220 at multiple angles.

[0067] In one embodiment, a damping assembly is also provided, and the damping assembly is applied to the foldable mobile terminal 10. The damping assembly includes a housing 311, an elastic member 313, a movable block 315, and a stopper 317. The elastic member 313 is disposed in the housing 311, and one end of the elastic member 313 abuts against the housing 311. The movable block 315 is slidably disposed in the housing 311 and abuts against the other end of the elastic member 313 and compresses the elastic member 313. The stopper 317 includes a connecting rod 316 and a stopper 318, the connecting rod 316 is penetrated through the housing 311, the elastic member 313, and the movable block 315, and one end of the connecting rod 316 protrudes from the housing 311, and the other end of the connecting rod 316 is fixedly connected to the stopper 318, and the elastic member 313 presses the movable block 315 so that the movable block 315 presses the stopper 318. The connecting rod 316 can rotate relative to the housing 311, and the connecting rod 316 can drive the stopper 318 to rotate relative to the movable block 315 to push the movable block 315 to slide in the housing 311. The snap ring 319 is clamped on one end of the connecting rod 316 protruding from the housing 311. The portion of the connecting rod 316 of the damping assembly protruding from the housing 311 can be connected to the housing assembly 200 of the foldable mobile terminal 10, so that the housing assembly 200 can be unfolded and closed through the damping assembly, and during the unfolding and closing process of the foldable mobile terminal 10, the damping assembly can provide the user with clear hand feedback to improve the user experience. The damping assembly is also conducive to the positioning of the housing assembly 200 of the foldable mobile terminal 10 at multiple unfolding angles to improve the convenience of user use.

[0068] In one embodiment, the movable block 315 includes an integrally formed body 3151 and a first boss 3153, wherein the first boss 3153 protrudes from one end of the body 3151 facing the stopper 318. The end of the stopper 318 facing the movable block 315 is provided with a groove 3181 and a second boss 3183, and the second boss 3183 and the groove wall of the groove 3181 are smoothly transitioned through an inclined surface 3185. When the connecting rod 316 drives the stopper 318 to rotate relative to the movable block 315, the first boss 3153 can slide from the second boss 3183 into the groove 3181 and can slide out from the groove 3181 to the second boss 3183. Further, as an implementable embodiment, the elastic member 313 can press against the movable block 315, and when the first boss 3153 slides onto the inclined surface 3185, the elastic member 313 can push the first boss 3153 to quickly slide into the groove 3181. For example, in one embodiment, when the damping assembly is applied to the foldable mobile terminal 10, during the folding process of the foldable mobile terminal 10, when the angle between the first shell 210 and the second shell 220 is less than or equal to 10 degrees, the first boss 3153 slides onto the inclined surface 3185, and under the action of the elastic member 313, the first boss 3153 quickly slides into the groove 3181, and the stopper 318 drives the connecting rod 316 to rotate quickly, thereby driving the first shell 210 to close quickly, that is, the first damping assembly 310 can drive the first shell 210 and the second shell 220 to close automatically. It is understandable that the second damping assembly 320 can adopt a similar structure, which will not be repeated here. It is understandable that by changing the direction of the inclined surface 3185, the above structure can also be used to achieve the rapid expansion of the first shell 210 relative to the second shell 220. The above structure is conducive to improving the user experience.
