When one of the frame bodies is subjected to a force parallel to the rotation shaft direction, or the two frame bodies are respectively subjected to forces parallel to the rotation shaft direction and in opposite directions, due to limited rigidity of the electronic device at the junction of the two frame bodies, the two frame bodies relatively translate along the rotation shaft direction, which affects the stability of relative rotation of the two frame bodies along the rotation shaft, and affects the quality of the electronic device.

[0023] The electronic device according to the embodiments of the present application is described below. Figures 1 to 6 The electronic device according to the embodiments of the present application is described below.

[0024] As shown in Figure 1 and Figure 2 The electronic device 100 provided by the embodiments of the present application includes a display screen 1, a shell 2 and a pulling assembly 3. The shell 2 includes a first frame 21 and a second frame 22, and the first frame 21 and the second frame 22 are rotationally connected by a hinge assembly 23 about a rotation axis L1, and the first frame 21 and the second frame 22 are used to support the display screen 1; the pulling assembly 3 is arranged in the shell 2, and the pulling assembly 3 includes a rotating bracket 31 and a plurality of elastic expansion members 32, the rotating bracket 31 is rotationally connected with the first frame 21, the first end of the elastic expansion member 32 is connected with the rotating bracket 31, the second end of the elastic expansion member 32 is rotationally connected with the second frame 22, and the expansion direction of at least one elastic expansion member 32 is arranged to intersect with the central axis of the second frame 22; wherein the rotation axis is perpendicular to the central axis.

[0025] The electronic device 100 provided in this application may be a mobile phone, tablet computer, laptop computer, handheld computer, vehicle-mounted electronic device, mobile Internet device (MID), augmented reality (AR) / virtual reality (VR) device, robot, wearable device, ultra-mobile personal computer (UMPC), netbook, or personal digital assistant (PDA), etc. It may also be a personal computer (PC), television (TV), ATM, or self-service machine, etc. The embodiments of this application do not specifically limit it.

[0026] The electronic device 100 can have a folded state and an unfolded state. When the electronic device 100 is in the folded state, the first frame 21 and the second frame 22 can be stacked, thereby reducing the size of the electronic device 100 for easy carrying. When the electronic device 100 is in the unfolded state, as shown... Figure 1 As shown, the first frame 21 and the second frame 22 can be located in the same plane, thereby obtaining a larger area electronic device 100. The first frame 21 and the second frame 22 can have the same structure and size, or they can have different sizes, but both are frames used to support the display screen 1. The first frame 21 and the second frame 22 can be arranged opposite each other along the central axis of the second frame.

[0027] The pulling component 3 is a structure used to limit the relative translation of the first frame 21 and the second frame 22. The rotating bracket 31 is rotatably connected to the first frame 21, allowing the rotating bracket 31 to rotate relative to the first frame 21 under the action of the elastic telescopic member 32. The elastic telescopic member 32 can have full elastic telescopic performance or only partial elastic telescopic performance. The elastic telescopic member 32 can achieve elastic telescopic performance by setting different structures, such as: spring structure, reciprocating bending structure, etc. The elastic telescopic member 32 can also be implemented using materials with elastic deformation function, such as: rubber. When one of the first frame 21 and the second frame 22 is subjected to an external force parallel to the rotation axis L1, the stretching direction of the elastic telescopic member 32 is its telescopic direction. Figure 2 In the embodiment shown, the elastic telescopic member 32 is elongated, and the telescopic direction of the elastic telescopic member 32 is the extension direction of the elastic telescopic member 32.

[0028] When one of the first frame 21 and the second frame 22 is subjected to an external force in the direction parallel to the rotation axis L1, the frame subjected to the external force tends to translate relative to the other frame, thereby pulling the elastic stretchable member 32 to stretch further, and the stretched pulling assembly 3 exerts an elastic deformation force on the two frames, which offsets all or part of the external force, thereby avoiding or reducing the translation misalignment of the first frame 21 and the second frame 22 due to the external force to some extent, and avoiding the electronic device 100 from generating an unrecoverable deformation at the junction of the two frames. The external force in the direction parallel to the rotation axis L1 can be a force directly acting on the frame in the direction parallel to the rotation axis L1 or can also be a component of a force acting on the frame in another direction.

[0029] When the electronic device 100 is in the folded state, the elastic stretchable member 32 can be in the relaxed state or in the stretched state, and when the electronic device 100 is in the unfolded state, the elastic stretchable member 32 can be in the relaxed state or in the stretched state. When the electronic device 100 is in the folded state and the elastic stretchable member 32 is in the stretched state, the electronic device 100 is switched from the folded state to the unfolded state, the pulling assembly 3 is further stretched, and the force exerted by the pulling assembly 3 on the housing 2 is increased; when the first frame 21 and the second frame 22 relatively translate along the rotation axis under the action of an external force, the force exerted by the elastic stretchable member 32 on the housing 2 is further increased. When the electronic device 100 is in the unfolded state and the pulling assembly 3 is in the relaxed state, the first frame 21 and the second frame 22 relatively translate along the rotation axis L1 under the action of an external force, the elastic stretchable member 32 stretches with the increase of the distance of translation, until the elastic stretchable member 32 exerts an elastic restoring force on the first frame 21 and the second frame 22 to limit the increase of the relative translation of the first frame 21 and the second frame 22 along the rotation axis L1.

[0030] By setting the rotation connection between the first frame 21 and the rotating support 31, the rotating support 31 can rotate relative to the first frame 21 under the action of the elastic restoring force of the elastic stretchable member 32, thereby adjusting the relative stretching length of each elastic stretchable member 32 within a certain range. For example, when one elastic stretchable member 32 stretches, the stretched elastic stretchable member 32 exerts an elastic restoring force on the second frame 22 and also exerts an elastic restoring force on the rotating support 31, thereby pulling the rotating support 31 to move relative to the first frame 21.

[0031] Optionally, by adjusting the length of the elastic stretchable member 32, the electronic device 100 is in the folded state, the pulling assembly 3 is in the relaxed state, the pulling assembly 3 does not exert elastic restoring force on the rotating support 31 and the second frame 22, and the electronic device 100 is in the unfolded state, the pulling assembly 3 is in the stretched state, and the pulling assembly 3 exerts elastic restoring force on the rotating support 31 and the second frame 22. Under the action of an external force, the first frame 21 and the second frame 22 have a tendency to translate relative to each other, and the elastic restoring force of the pulling assembly 3 in the stretched state can counteract the external force, thereby ensuring that the first frame 21 and the second frame 22 do not translate relative to each other along the rotation axis L1.

[0032] In the present application, by providing the pulling assembly 3 and setting the extension direction of the at least one elastic stretchable member 32 to intersect the central axis of the second frame 22, the elastic restoring force of the elastic stretchable member 32 in the stretched state can counteract all or part of the external force when the first frame 21 and the second frame 22 are subjected to an external force, thereby to some extent avoiding or reducing the relative translation of the first frame 21 and the second frame 22 along the rotation axis L1 caused by the external force, avoiding the generation of irreversible deformation of the electronic device 100 at the hinge of the first frame 21 and the second frame 22, improving the stability of the relative rotation of the first frame 21 and the second frame 22 along the rotation axis L1, and improving the quality of the electronic device 100.

[0033] The first frame 21 and the second frame 22 can have an approximately rectangular shape. The rotating support 31 can be arranged on the side of the first frame 21 away from the display screen 1. Optionally, the side of the first frame 21 away from the display screen 1 has a mounting protrusion, and the rotating support 31 is connected with the mounting protrusion to realize the connection of the rotating support 31 with the first frame 21.

[0034] Please refer to Figure 3 In an embodiment, the plurality of elastic stretchable members 32 includes a first elastic stretchable member 321 and a second elastic stretchable member 322, the first end of the first elastic stretchable member 321 and the first end of the second elastic stretchable member 322 are respectively connected with the rotating support 31, and the second end of the first elastic stretchable member 321 and the second end of the second elastic stretchable member 322 are respectively connected with the second frame 22.

[0035] The first elastic stretch member 321 and the second elastic stretch member 322 can have the same structure or can not have the same structure, but both have elastic stretching performance. The stretching direction of at least one of the first elastic stretch member 321 and the second elastic stretch member 322 is arranged to intersect the central axis L2 of the second frame body 22. Of course, the stretching direction of the first elastic stretch member 321, the stretching direction of the second elastic stretch member 322, and the rotation shaft L1 can also be arranged to intersect each other. By arranging the first elastic stretch member 321 and the second elastic stretch member 322, the limiting capability of the pulling assembly 3 is improved.

[0036] In an embodiment, the first elastic stretch member 321 and the second elastic stretch member 322 are arranged to intersect. When the second frame body 22 is subjected to an external force in the first direction X and has a parallel translation trend along the rotation shaft L1, the first elastic stretch member 321 is contracted, the second elastic stretch member 322 is stretched, and the second elastic stretch member 322 can drive the rotating support 31 to rotate relative to the first frame body 21, thereby reducing the stretching length of the second elastic stretch member 322 and increasing the stretching length of the first elastic stretch member 321 through the rotation of the rotating support 31, so that the stretched first elastic stretch member 321 can also exert an elastic restoring force on the shell 2, and the elastic restoring force can be used to offset the external force, thereby limiting the translation between the first frame body 21 and the second frame body 22 along the rotation shaft L1; when the second frame body 22 is subjected to an external force away from the first direction X and has a parallel translation trend along the rotation shaft L1, the second elastic stretch member 322 is contracted, the first elastic stretch member 321 is stretched, and the first elastic stretch member 321 can drive the rotating support 31 to rotate relative to the first frame body 21, thereby reducing the stretching length of the first elastic stretch member 321 and increasing the stretching length of the second elastic stretch member 322 through the rotation of the rotating support 31, so that the stretched second elastic stretch member 322 can also exert an elastic restoring force on the shell 2, and the elastic restoring force can be used to offset the external force, thereby limiting the translation between the first frame body 21 and the second frame body 22 along the rotation shaft L1.

[0037] By arranging the first elastic stretch member 321 and the second elastic stretch member 322 to be connected to the first frame body 21 through the rotating support 31, the first elastic stretch member 321 and the second elastic stretch member 322 can be assembled with the rotating support 31 first, and then the rotating support 31 is connected to the first frame body 21, thereby facilitating assembly. By arranging the first elastic stretch member 321 and the second elastic stretch member 322 to intersect, when the first frame body 21 and the second frame body 22 are subjected to an external force in the direction parallel to the rotation shaft L1, the first elastic stretch member 321 and the second elastic stretch member 322 can both limit the relative translation of the first frame body 21 and the second frame body 22, thereby improving the overall limiting capability of the pulling assembly 3.

[0038] Please refer to Figure 4In some embodiments, the rotating support 31 comprises a rotating part 31a, a first connecting part 31b and a second connecting part 31c, the rotating part 31a is rotatably connected with the first frame 21; the first connecting part 31b is connected with the rotating part 31a, and a first end of the first elastic stretchable part 321 is connected with the first connecting part 31b; the second connecting part 31c is connected with the rotating part, and a first end of the second elastic stretchable part 322 is connected with the second connecting part 31c; the extending directions of the first connecting part 31b and the second connecting part 31c intersect.

[0039] The first connecting part 31b, the second connecting part 31c and the rotating part 31a can be in the form of strips connected in sequence, or can be in the form of Figure 4 irregular shapes in the illustrated embodiments.

[0040] By setting the extending directions of the first connecting part 31b and the second connecting part 31c intersecting, the connection of the first elastic stretchable part 321 with the rotating support 31 and the connection of the second elastic stretchable part 322 with the rotating support 31 can be spaced apart, so that the rotating support 31 has a greater adjustment effect. The greater the distance interval, the greater the range of the relative stretching length of the first elastic stretchable part 321 and the second elastic stretchable part 322 adjusted by the rotating support 31.

[0041] In some embodiments, one end of the first elastic stretchable part 321 and the second elastic stretchable part 322 are symmetrically arranged relative to the central axis L2, thereby facilitating the calculation of the elastic deformation force required by the first elastic stretchable part 321 and the second elastic stretchable part 322, so that the first elastic stretchable part 321 and the second elastic stretchable part 322 can both achieve better limiting effect under the action of external force in opposite directions. Alternatively, the pulling assembly 3 is symmetrically arranged about the central axis L2 when the electronic device 100 is in the unfolded state. When the electronic device 100 is in the folded state, only the rigid parts of the first elastic stretchable part 321 and the second elastic stretchable part 322 are symmetrically arranged about the central axis L2 due to the irregular bending of the flexible parts of the first elastic stretchable part 321 and the second elastic stretchable part 322.

[0042] In some embodiments, the second frame 221 comprises a first side edge 22a and a second side edge 22b arranged opposite along the extending direction of the rotation axis L1, and further comprises a first fixing part 222 and a second fixing part 223, the first fixing part 222 is connected with the first side edge 22a, the second fixing part 223 is connected with the second side edge 22b, the first elastic stretchable part 321 is connected with the first fixing part 222, and the second elastic stretchable part 322 is connected with the second fixing part 223.

[0043] By setting the first fixing member 222 and the second fixing member 223, the first elastic member 321 and the second elastic member 322 are respectively fixed to the second frame 22. By setting the first fixing member 222 on the first side 22a and the second fixing member 223 on the second side 22b, the sensitivity of the first elastic member 321 and the second elastic member 322 to stretching with translation is improved when the first frame 21 and the second frame 22 have a tendency to translate along the rotation axis L1.

[0044] Please refer to Figure 1 In some embodiments, the display screen 1 is a flexible display screen, and the display screen 1 includes a bending display area 12 and a non-bending display area 11. The first frame 21 and the second frame 22 respectively support the non-bending display area 11. The electronic device 100 has an unfolded state and a folded state. When the electronic device 100 is in the unfolded state, the elastic member 32 has a first length. When the electronic device 100 is in the folded state, the bending display area 12 is at least partially bent into an arc shape, and the elastic member 32 has a second length. The first length is less than the second length.

[0045] The display screen 1 can include the bending display area 12 and at least two non-bending display areas 11. The bending display area 12 is connected to two adjacent non-bending display areas 11. The electronic device 100 can have a folded state and an unfolded state. When the electronic device 100 is in the folded state, the display screen 1 is also in the folded state, and the bending display area 12 is at least partially curved into an arc shape around the rotation axis L1. The two non-bending display areas 11 connected to the bending display area 12 can be stacked to reduce the volume of the electronic device 100, thereby facilitating portability. Figure 1 As shown in FIG. 1, the bending display area 12 is unfolded, and the bending display area 12 and the non-bending display areas 11 connected to the bending display area 12 can be flatly displayed together, thereby obtaining a larger display area and displaying more content. Optionally, the number of bending display areas 12 can be one, and the number of non-bending display areas 11 can be two. The two non-bending display areas 11 are arranged on both sides of the bending display area 12, and the rotation axis L1 is arranged in line with the center line of the bending display area 12.

[0046] The first frame 21 and the second frame 22 can be used to support adjacent non-bending display areas 11 respectively, and the bending display area 12 can be arranged corresponding to the hinge assembly. In the case that the electronic device 100 is in the folded state, the first frame 21 and the second frame 22 are stacked along the thickness direction of the display screen 1, and in the case that the electronic device 100 is in the unfolded state, the first frame 21 and the second frame 22 are arranged relative to each other along the central axis L2 of the second frame. Since one end of the elastic stretchable piece 32 is connected with the first frame 21 and the other end is connected with the second frame 22, the pulling assembly 3 necessarily crosses the bending display area 12, that is, in the case that the electronic device 100 is in the unfolded state, the projection of the elastic stretchable piece 32 on the display screen 1 falls partly on the adjacent two non-bending display areas 11 and partly on the bending display area 12.

[0047] The first length is smaller than the second length, which can be understood as that in the case that the electronic device 100 is switched from the folded state to the unfolded state, the elastic stretchable piece 32 is elongated, and in the case that the electronic device 100 is switched from the unfolded state to the folded state, the elastic stretchable piece 32 is contracted.

[0048] Please refer to Figure 5 In an embodiment, the elastic stretchable piece 32 comprises a flexible elastic piece 323, which is in a tensioned state in the case that the electronic device 100 is in the unfolded state, and the projection of the flexible elastic piece 323 on the display screen 1 falls at least partly into the bending display area.

[0049] The flexible elastic piece 323 has both flexibility and elasticity, and can be bent together with the folding of the display screen 1. The flexible elastic piece 323 can be a flexible rope with consistent cross-sectional size and elasticity, or a strip structure with elasticity, and part of the area of the strip structure is thinned, so that the thinned area is thinner than other parts and has better bending property. In this embodiment, only the flexible elastic piece 323 is arranged to be connected with the rotating support 31 and the second frame 22, so that the assembly steps are simple.

[0050] Please refer to Figure 6 In another embodiment, the elastic stretchable piece 32 comprises a connecting rod 324 and a flexible elastic piece 323, the connecting rod 324 is rotationally connected with the rotating support 31; one end of the flexible elastic piece 323 is connected with the connecting rod 324, and the other end is rotationally connected with the second frame 22, and the flexible elastic piece 323 is in a tensioned state in the case that the electronic device 100 is in the unfolded state, and the projection of the flexible elastic piece 323 on the display screen falls at least partly into the bending display area.

[0051] The connecting rod 324 is rotationally connected with the first frame 21, so that the connecting rod 324 can rotate around the first frame 21 under the action of the flexible elastic member 323. The connecting rod 324 can be provided with a hook, a clamping member or the like connected with the flexible elastic member 323, so as to facilitate the connection between the connecting rod 324 and the first frame 21. By arranging the connecting rod 324, the flexible elastic member 323 can be more stably connected with the first frame 21.

[0052] In some other embodiments, the elastic telescopic member 32 includes a connecting rod 324, a cable 325 and an elastic body 326, the connecting rod 324 is rotationally connected with the rotating support 31, the elastic body 326 is rotationally connected with the second frame 22, one end of the cable 325 is connected with the connecting rod 324, and the other end of the cable 325 is connected with the elastic body 326. When the electronic device 100 is in the unfolded state, the cable 325 is in the tension state, and the projection of the cable 325 on the display screen at least partially falls into the bending display area.

[0053] The cable 325 in the embodiment can have elasticity or can not have elasticity. The elastic body 326 can be a spring, a rubber having elasticity or the like. When the electronic device 100 is in the folded state, the cable 325 is in a non-straight state, and the flexible elastic member 323 is in a contracted state; when the electronic device 100 is in the unfolded state, the cable 325 is in a stretched straight state, and the flexible elastic member 323 is in an elongated state.

[0054] The embodiments of the application are described above in combination with the drawings, but the application is not limited to the above specific embodiments, and the above specific embodiments are only illustrative but not restrictive, and those skilled in the art can make many forms under the inspiration of the application without departing from the scope of the application and the protection scope of the claims.
