Referring to fig. 1 and 2, in one embodiment, the folding mobile terminal 10 is a smart phone. The folder-type mobile terminal 10 includes a flexible screen 100, a housing assembly 200, and a folding mechanism 300. The flexible screen 100 has a bendable characteristic, and the flexible screen 100 can display information and provide an interactive interface for a 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. Referring also to fig. 3, the folding mechanism 300 includes a first damper assembly 310, a second damper assembly 320, and a connecting member 330, the connecting member 330 being connected to the first damper assembly 310 and the second damper assembly 320, respectively, the first damper assembly 310 being connected to the first housing 210, and the second damper assembly 320 being connected to the second housing 220. The first housing 210 can rotate relative to the second housing 220 through the folding mechanism 300 to realize the unfolding and folding of the folding mobile terminal 10. Referring to fig. 4, the housing assembly 200 of the folder-type mobile terminal 10 is in an unfolded state.

Referring to fig. 3, in an 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 communicated with the mounting groove 335, the first damping element 310 is disposed in the first mounting hole 331, the connecting rod 316 of the first damping element 310 protrudes out of the first mounting hole 331 and is fixedly connected with the first housing 210, the second damping element 320 is disposed in the second mounting hole 333, and the second damping element 320 protrudes out of the second mounting hole 333 and is fixedly connected with the second housing 220. Further, the folder-type mobile terminal 10 includes a cover plate 340 covering the mounting groove 335, and the cover plate 340 is used for defining the position of the first damping member 310 in the first mounting hole 331 so as to prevent the first damping member 310 from being removed from the first mounting hole 331. Likewise, the cover plate 340 can define the position of the second damping member 320 within the second mounting hole 333 to prevent the second damping member 320 from being removed from the second mounting hole 333.

In one embodiment, the flexible screen 100 is disposed on a side of the cover plate 340, and when the foldable mobile terminal 10 is folded, the displayable region of the flexible screen 100 is exposed out of the housing assembly 200. The flexible screen 100 is exposed out of the housing assembly 200 when the foldable mobile terminal 10 is in the folded state, and the user can use the foldable mobile terminal 10 normally when the foldable mobile terminal is in the folded state.

Referring to fig. 5 and 6, the housing assembly 200 is in a closed state. In the process of rotating 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 folder-type mobile terminal 10, the first housing 210 rotates relative to the connecting member 330 via the first damping member 310, the second housing 220 rotates relative to the connecting member 330 via the second damping member 320, and the rotational damping of the first damping member 310 is greater than the rotational damping of the second damping member 320.

It is understood that rotational damping refers to the amount of rotational resistance during rotation, and that rotational damping represents the amount of rotational torque generated by the resistance during rotation that resists rotation. It will be appreciated that the rotational damping may be continuous, for example, in this embodiment, the rotational damping of the first damping assembly 310 varies continuously as the first housing 210 rotates relative to the connector 330, and the rotational damping provides an obstruction to the rotation of the first housing 210 relative to the connector 330. The rotational damping of the second damping assembly 320 continuously changes as the second housing 220 rotates relative to the connector 330, and the rotational damping provides an obstruction to the rotation of the second housing 220 relative to the connector 330. Rotational damping may provide positive tactile feedback to the user and may also be used for positioning of the first and

second housings

210, 220 relative to the connector 330. For example, in an embodiment, with the folding mobile terminal 10 having the above-described structure, when the included angle between the first housing 210 and the second housing 220 is in the range of 45 degrees to 180 degrees, the first housing 210 and the second housing 220 may be positioned at any angle within the included angle range, so as to facilitate the user to use the folding mobile terminal 10. In an embodiment, with the foldable mobile terminal 10 having the above structure, the included angle between the first housing 210 and the second housing 220 can be in a plurality of stable states. For example, when the included angle between the first housing 210 and the second housing 220 is 90 degrees, 120 degrees, 135 degrees, etc., the first housing 210 and the second housing 220 can be in a stable positioning state, so that the user can use the device conveniently.

Referring to fig. 7 and 8, in an embodiment, during the folding of the folding 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. Specifically, in the present embodiment, when the first housing 210 rotates 90 degrees relative to the connecting element 330 with the folded mobile terminal 10 in a flat state as a reference zero position of the angle, the side of the first housing 210 facing away from the flexible screen 100 abuts against the connecting element 330, and the connecting element 330 can limit the rotation of the first housing 210. Similarly, when the second housing 220 rotates 90 degrees relative to the connection member 330, the side of the second housing 220 facing away from the flexible screen 100 may also abut against the connection member 330 to limit the rotation range of the second housing 220. With the above arrangement, the flexible screen 100, the first damping assembly 310 and the second damping assembly 320 can be protected by limiting the rotation range of the first housing 210 or the second housing 220 by the connecting member 330, so as to prevent the flexible screen 100 or the folding mechanism 300 from being damaged due to an excessive rotation angle. It is understood that in other embodiments, the side of the first housing 210 facing away from the flexible screen 100 may abut against the connection member 330 when the rotation angle of the first housing 210 relative to the connection member 330 is greater than 90 degrees or less than 90 degrees, and the side of the second housing 220 facing away from the flexible screen 100 may abut against the connection member 330 when the rotation angle of the second housing 220 relative to the connection member 330 is greater than 90 degrees or less than 90 degrees.

It is understood that since the rotational damping of the first damping member 310 is greater than the rotational damping of the second damping member 320, the second housing 220 is less resistant to rotation during the closing of the folder-type mobile terminal 10 and therefore can rotate relative to the connecting member 330 prior to the first housing 210. When the side of the second housing 220 facing away from the flexible screen 100 abuts against the connecting member 330, the connecting member 330 limits the rotation of the second housing 220, and the first housing 210 can rotate relative to the connecting member 330, so that the folding mobile terminal 10 can be gradually folded. With the above arrangement, the expressive force of the folding mobile terminal 10 can be improved, and the user experience can be further improved.

Referring to fig. 9 and 10, the first damping member 310 includes a housing 311, an elastic member 313, a movable block 315, a stopper 317, and a snap ring 319, and 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 provided in the housing 311, abuts against the other end of the elastic member 313, and compresses the elastic member 313. The stop 317 includes a connecting rod 316 and a stop 318, the connecting rod 316 can be integrally formed with the stop 318, and the connecting rod 316 can be detachably connected or non-detachably connected with the stop 318. The connecting rod 316 is substantially cylindrical, the connecting rod 316 penetrates through the housing 311, the elastic member 313 and the movable block 315, one end of the connecting rod 316 protrudes out of the housing 311 and is fixedly connected with the first housing 210, the other end of the connecting rod 316 is fixedly connected with the stopper 318, and the elastic member 313 presses the movable block 315 so that the movable block 315 presses the stopper 318. The snap ring 319 is engaged with an end of the connecting rod 316 protruding from the housing 311 to fix the position of the housing 311 in the axial direction of the connecting rod 316. During the rotation of the first housing 210 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 is pressed against the movable block 315, the friction force generated on the contact surface of the movable block 315 and the stopper 318 generates a resistance to the rotation of the movable block 315 relative to the stopper 318, i.e., generates a rotational damping.

The internal structure and principle of the second damping element 320 are similar to those of the first damping element 310, and are not described herein again. It will be appreciated that when the friction moment of the movable mass 315 of the first damping assembly 310 against the stop 318 is greater than the friction moment within the second damping assembly 320, a greater rotational damping of the first damping assembly 310 than the second damping assembly 320 is achieved. It is understood that the magnitude of the friction torque is related to the compression elasticity of the elastic member 313 and also to the friction factor between the movable block 315 and the stopper 318. In the present embodiment, the compression elastic force of the elastic member 313 in the first damping unit 310 is greater than that of the elastic member 313 in the second damping unit 320. In one embodiment, the first damping assembly 310 has a rotational damping of 100N and the second damping assembly 320 has a rotational damping of 30N. In an embodiment, the elastic element 313 is a spring, and in other embodiments, the elastic element 313 may be a spring sheet or an elastic column, which is not described herein again.

In the foldable mobile terminal 10, since the rotational damping of the first damping element 310 is greater than the rotational damping of the second damping element 320, during the unfolding and folding processes of the foldable mobile terminal 10, the second damping element 320 can be unfolded or folded before the first damping element 310, and the first damping element 310 and the second damping element 320 can provide a clear feel for a user to improve the user experience. The provision of first and second damping

assemblies

310 and 320 also facilitates the positioning of first and

second housings

210 and 220 at multiple angles.

Referring to fig. 11 and 12, the movable block 315 includes a body 3151 and a first protrusion 3153, and the first protrusion 3153 protrudes from an end of the body 3151 facing the stopper 318. One end of the stop block 318 facing the movable block 315 is provided with a groove 3181 and a second boss 3183, and the groove wall of the groove 3181 and the second boss 3183 are smoothly transited through an inclined surface 3185. In the process that the first housing 210 drives the stopper 318 to rotate relative to the movable block 315 through the connection rod 316, the first boss 3153 can slide into the groove 3181 from the second boss 3183 and can slide out of the groove 3181 onto the second boss 3183.

Further, referring to fig. 13 and 14, as an implementation manner, during the process of folding the folding mobile terminal 10, the elastic member 313 can abut against the movable block 315, and when the first protrusion 3153 slides onto the inclined surface 3185, the elastic member 313 can push the first protrusion 3153 to slide into the groove 3181 quickly. For example, in an embodiment, in a process of folding the foldable mobile terminal 10, when an included angle between the first housing 210 and the second housing 220 is less than or equal to 10 degrees, the first protrusion 3153 slides onto the inclined surface 3185, and under the action of the elastic member 313, the first protrusion 3153 slides into the groove 3181 quickly, the stopper 318 drives the connecting rod 316 to rotate quickly, so as to drive the first housing 210 to fold quickly, that is, the first damping element 310 can drive the first housing 210 and the second housing 220 to fold automatically. It is understood that the second damping assembly 320 may have a similar structure and will not be described in detail herein. It will be appreciated that the above-described structure may also be utilized to achieve rapid deployment of the first housing 210 relative to the second housing 220 by changing the direction of the ramp 3185. The structure is favorable for improving the experience of the user. It is understood that changing the angle of the slope can change the speed at which the first housing 210 and the second housing 220 are quickly closed.

In one embodiment, a folding assembly is provided for a folding mobile terminal 10, the folding assembly including a housing component 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 damper assembly 310, a second damper assembly 320, and a connecting member 330, the connecting member 330 being connected to the first damper assembly 310 and the second damper assembly 320, respectively, the first damper assembly 310 being connected to the first housing 210, and the second damper assembly 320 being connected to the second housing 220. The first housing 210 can rotate relative to the second housing 220 through the folding mechanism 300 to realize the unfolding and folding of the folding mobile terminal 10. During the process of folding the folder-type mobile terminal 10, the first housing 210 rotates relative to the connecting member 330 via the first damping member 310, the second housing 220 rotates relative to the connecting member 330 via the second damping member 320, and 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. In one embodiment, during the folding of the folding mobile terminal 10, the second housing 220 can abut against the connecting member 330 to limit the rotation range of the second housing 220 relative to the connecting member 330. The above arrangement, using the connection member 330 to limit the rotation range of the first housing 210 or the second housing 220, can protect the flexible screen 100, the first damping member 310 and the second damping member 320 of the foldable mobile terminal 10 to prevent the flexible screen 100 or the folding mechanism 300 from being damaged due to an excessive rotation angle.

Further, in one embodiment, the rotational damping of the first damping assembly 310 is greater than the rotational damping of the second damping assembly 320. Since the rotational damping of the first damping member 310 is greater than the rotational damping of the second damping member 320, the second housing 220 is less resistant to rotation during the folding of the folder-type mobile terminal 10 and therefore can rotate relative to the connecting member 330 before the first housing 210. When the side of the second housing 220 facing away from the flexible screen 100 abuts against the connecting member 330, the connecting member 330 limits the rotation of the second housing 220, and the first housing 210 can rotate relative to the connecting member 330, so that the folding mobile terminal 10 can be gradually folded. With the above arrangement, the expressive force of the folding mobile terminal 10 can be improved, and the user experience can be further improved.

Specifically, take the first damping assembly 310 as an example. The first damping member 310 includes a housing 311, an elastic member 313, a movable block 315, a stopper 317, and a snap ring 319, wherein 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 provided in the housing 311, abuts against the other end of the elastic member 313, and compresses the elastic member 313. The stopping member 317 includes a connecting rod 316 and a stopper 318, the connecting rod 316 penetrates through the housing 311, the elastic member 313 and the movable block 315, one end of the connecting rod 316 protrudes out of the housing 311 and is fixedly connected with the first casing 210, the other end of the connecting rod 316 is fixedly connected with the stopper 318, and 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 at one end of the connecting rod 316 protruding from the housing 311. During the rotation of the first housing 210 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.

When the foldable assembly is applied to the foldable mobile terminal 10, since the rotational damping of the first damping element 310 is greater than the rotational damping of the second damping element 320, the second damping element 320 can be unfolded or folded before the first damping element 310 during the unfolding and folding processes of the foldable mobile terminal 10, and the first damping element 310 and the second damping element 320 can provide a clear feel to the user to enhance the user experience. The provision of first and second damping

assemblies

310 and 320 also facilitates the positioning of first and

second housings

210 and 220 at multiple angles.

It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the concept of the present application, which falls within the scope of protection of the present application.
