The foldable mobile terminal 10 includes a flexible screen 100 , a case assembly 200 and a folding mechanism 300 . The flexible screen 100 has the characteristic of being bendable, and the flexible screen 100 can display information and provide an interactive interface for the user. The casing assembly 200 includes a first casing 210 and a second casing 220 , and the flexible screen 100 is covered on the first casing 210 and the second casing 220 and is connected with the first casing 210 and the second casing 220 , respectively. Referring to FIG. 3 at the same time, the folding mechanism 300 includes a first damping assembly 310, a second damping assembly 320 and a connecting member 330. The connecting member 330 is respectively connected with the first damping assembly 310 and the second damping assembly 320. A housing 210 is connected, and the second damping assembly 320 is connected with the second housing 220 . The first casing 210 can be rotated relative to the second casing 220 through the folding mechanism 300 to realize unfolding and folding of the foldable mobile terminal 10 . Referring to FIG. 4 , the case assembly 200 of the folder-type mobile terminal 10 is in an unfolded state.

Referring to FIG. 3 , in one embodiment, the connecting member 330 is provided with a first mounting hole 331 , a second mounting hole 333 and a mounting slot 335 , and the first mounting hole 331 and the second mounting hole 333 are respectively communicated with the mounting slot 335 , The first damping component 310 is inserted through the first installation hole 331 , the connecting rod 316 of the first damping component 310 protrudes out of the first installation hole 331 and is fixedly connected with the first housing 210 , and the second damping component 320 is inserted through the first installation hole 331 .

Further, the foldable mobile terminal 10 includes a cover plate 340 covering the installation slot 335. The cover plate 340 is used to define the position of the first damping component 310 in the first installation hole 331, so as to prevent the first damping component 310 from being removed from the first mounting hole 331. come out from the mounting hole 331 . Likewise, the cover plate 340 can define the position of the second damping assembly 320 in the second mounting hole 333 to prevent the second damping assembly 320 from coming out of the second mounting hole 333 .

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 above-mentioned foldable mobile terminal 10 is in the folded state, the flexible screen 100 is exposed to the housing assembly 200 , and in the folded state, the user can use the foldable mobile terminal 10 normally.

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

Specifically, referring to FIGS. 7 and 8 , the first damping assembly 310 includes a casing 311 , an elastic member 313 , a movable block 315 , a stop member 317 and a snap ring 319 , and the casing 311 is fixedly connected with the connecting member 330 . The elastic member 313 is disposed in the casing 311 , and one end of the elastic member 313 is in contact with the casing 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 blocking block 318 . The connecting rod 316 can be integrally formed with the blocking block 318 , and the connecting rod 316 can also be detachably or non-detachably connected with the blocking block 318 . The connecting rod 316 is substantially cylindrical, and the connecting rod 316 passes through the casing 311 , the elastic member 313 and the movable block 315 , and one end of the connecting rod 316 protrudes from the casing 311 and is fixedly connected with the first casing 210 . The other end of the 316 is fixedly connected with the blocking block 318 , and the elastic member 313 presses the movable block 315 to make the movable block 315 press against the blocking block 318 . The snap ring 319 is clamped on one end of the connecting rod 316 protruding from the casing 311 to fix the position of the casing 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 blocking block 318 to rotate relative to the movable block 315 through the connecting rod 316 , so that the movable block 315 is relative to the casing 311 slide. Since the elastic member 313 is in a compressed state and presses against the movable block 315, the frictional force generated on the contact surface of the movable block 315 and the stopper 318 produces resistance to the rotation of the movable block 315 relative to the stopper 318, that is, a rotation occurs. damping.

The internal structure and principle of the second damping component 320 are similar to the internal structure and principle of the first damping component 310 , and will not be repeated here. It can be understood that, when the frictional distance between the movable block 315 of the first damping assembly 310 and 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 that of the second damping Rotational damping of assembly 320 . It can be understood that the magnitude of the friction torque is related to the compressive elastic force of the elastic member 313 , and is also related to the friction factor between the movable block 315 and the blocking block 318 . In this embodiment, the compressive elastic force of the elastic member 313 in the first damping assembly 310 is greater than the compressive elastic force of the elastic member 313 in the second damping assembly 320 . In one embodiment, the rotational damping of the first damping component 310 is 100N, and the rotational damping of the second damping component 320 is 30N. In one embodiment, the elastic member 313 is a spring, and in other embodiments, the elastic member 313 can be an elastic sheet or an elastic column, which will not be repeated here.

In the above-mentioned folding 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, in the process of unfolding and folding the folding mobile terminal 10, the second damping component 320 can precede the first damping The components 310 are unfolded or folded, and the first damping components 310 and the second damping components 320 can provide a user with a clear feel to improve user experience. The arrangement of the first damping assembly 310 and the second damping assembly 320 also facilitates the positioning of the first housing 210 and the second housing 220 at multiple angles.

Referring to FIGS. 9 and 10 , the movable block 315 includes an integrally formed body 3151 and a first boss 3153 , and the first boss 3153 protrudes from an end of the body 3151 facing the stopper 318 .

When the first housing 210 drives the block 318 to rotate relative to the movable block 315 through the connecting rod 316 , the first boss 3153 can slide into the groove 3181 from the second boss 3183 and can slide from the groove 3181 out to the second boss 3183. Further, referring to FIG. 11 and FIG. 12 , as an embodiment, in the process of folding the mobile foldable 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 slide into the groove 3181 quickly. For example, in one embodiment, when the angle between the first casing 210 and the second casing 220 is less than or equal to 10 degrees during the folding process of the folding mobile terminal 10 , the first boss 3153 slides onto the inclined surface 3185 , under the action of the elastic member 313, the first boss 3153 quickly slides into the groove 3181, the stopper 318 drives the connecting rod 316 to rotate rapidly, and then drives the first housing 210 to quickly close, that is, the first damping component 310 can drive the The first casing 210 and the second casing 220 are automatically closed. It can be understood that, the second damping assembly 320 may adopt a similar structure, and details are not described herein again. It can be understood that, by changing the direction of the inclined surface 3185 , the above structure can also be used to realize the rapid expansion of the first casing 210 relative to the second casing 220 . The above structure is beneficial to improve user experience. It can be understood that by changing the angle of the inclined plane, the speed at which the first casing 210 and the second casing 220 are rapidly closed can be changed.
