An electronic device according to an embodiment of the present application is described below with reference to fig. 1 to 6.

As shown in fig. 1 and 2, an embodiment of the present application provides an electronic device 100, where the electronic device 100 includes a display screen 1, a housing 2, and a pulling assembly 3. The housing 2 includes a first frame 21 and a second frame 22, the first frame 21 and the second frame 22 are rotatably connected around a rotation axis L1 by a hinge assembly 23, and the first frame 21 and the second frame 22 are used for supporting the display screen 1; the pulling assembly 3 is arranged in the shell 2, the pulling assembly 3 comprises a rotating support 31 and a plurality of elastic expansion pieces 32, the rotating support 31 is rotatably connected with the first frame body 21, a first end of each elastic expansion piece 32 is connected with the rotating support 31, a second end of each elastic expansion piece 32 is rotatably connected with the second frame body 22, and the expansion direction of at least one elastic expansion piece 32 is intersected with the central axis of the second frame body 22; wherein, the rotating shaft is vertical to the central axis.

The electronic device 100 provided in the present application may be a mobile phone, a tablet computer, a notebook computer, a palmtop computer, a vehicle-mounted electronic device, a Mobile Internet Device (MID), an Augmented Reality (AR)/Virtual Reality (VR) device, a robot, a wearable device, a super-mobile personal computer (UMPC), a netbook or a Personal Digital Assistant (PDA), etc., and may also be a Personal Computer (PC), a television (television, TV), a teller machine or a self-service machine, etc., which have a display screen 1, and the embodiments of the present application are not particularly limited.

The electronic device 100 may have a folded state and an unfolded state. The electronic apparatus 100 is in a folded state, and the first frame body 21 and the second frame body 22 can be stacked, so that the volume of the electronic apparatus 100 is reduced, and the electronic apparatus is convenient to carry. When the electronic apparatus 100 is in the unfolded state, as shown in fig. 1, the first frame body 21 and the second frame body 22 can be in the same plane, thereby obtaining a larger area of the electronic apparatus 100. The first frame body 21 and the second frame body 22 may have the same structure and size or may have different sizes, but both are frame bodies for supporting the display screen 1. The first frame body 21 and the second frame body 22 may be disposed to face each other along a central axis of the second frame body.

The pulling assembly 3 is a structure for restricting the relative translation of the first frame body 21 and the second frame body 22. The rotating bracket 31 is rotatably connected to the first frame 21 such that the rotating bracket 31 can rotate relative to the first frame 21 by the elastic expansion member 32. The elastic expansion piece 32 may have all elastic expansion properties, or may only partially have elastic expansion properties, and the elastic expansion piece 32 may be elastically expanded and contracted by setting different structures, for example: spring structures, reciprocating bending structures, etc. The elastic expansion elements 32 can also be realized by materials having an elastic deformation function, such as: rubber. When one of the first frame body 21 and the second frame body 22 receives an external force in a direction parallel to the rotation axis L1, the stretching direction of the elastic extensible member 32 is the extending and contracting direction thereof. In the embodiment shown in fig. 2, the elastic expansion member 32 is in a long strip shape, and the expansion direction of the elastic expansion member 32 is the extension direction of the elastic expansion member 32.

When one of the first frame 21 and the second frame 22 receives an external force along a direction parallel to the rotation axis L1, the frame receiving the external force tends to move horizontally relative to the other frame, so as to pull the elastic expansion element 32 to further stretch, the stretching pulling assembly 3 applies an elastic deformation force to the two frames, the elastic deformation force offsets all or part of the external force, thereby avoiding or reducing the translational dislocation of the first frame 21 and the second frame 2 caused by the external force to a certain extent, and avoiding the unrecoverable deformation of the electronic device 100 at the junction of the two frames. The external force in the direction parallel to the rotation axis L1 may be a component of a force directly acting on the frame in the direction parallel to the rotation axis L1 or a force acting on the frame in another direction.

When the electronic device 100 is in the folded state, the elastic expansion element 32 may be in the relaxed state or in the stretched state, and when the electronic device 100 is in the unfolded state, the elastic expansion element 32 may be in the relaxed state or in the stretched state. When the electronic device 100 is in the folded state and the elastic extensible member 32 is in the extended state, the electronic device 100 is switched from the folded state to the extended state, the pulling member 3 is further extended, and the force applied by the pulling member 3 to the housing 2 is increased; when the first frame 21 and the second frame 22 are relatively translated along the rotation axis by an external force, the urging force of the elastic expansion piece 32 to the housing 2 is further increased. When the electronic device 100 is in the expanded state and the pulling assembly 3 is in the relaxed state, under the action of an external force, the first frame 21 and the second frame 22 perform relative translation along the rotation axis L1, and the elastic extensible member 32 stretches as the distance of the translation increases until the elastic extensible member 32 applies an elastic restoring force to the first frame 21 and the second frame 22, so as to limit the increase of the relative translation between the first frame 21 and the second frame 22 along the direction of the rotation axis L1.

By arranging the first frame body 21 and the rotating bracket 31 to be rotatably connected, the rotating bracket 31 can rotate relative to the first frame body 21 under the action of the elastic restoring force of the elastic expansion pieces 32, so that the relative stretching length of each elastic expansion piece 32 can be adjusted within a certain range. For example, an elastic stretching member 32 is stretched, and the stretched elastic stretching member 32 applies an elastic restoring force to the second frame 22 and also applies an elastic restoring force to the rotating bracket 31, thereby pulling the rotating bracket 31 to move relative to the first frame 21.

Alternatively, by adjusting the length of the elastic expansion piece 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 apply an elastic restoring force to the rotating bracket 31 and the second frame 22, and when the electronic device 100 is in the unfolded state, the pulling assembly 3 is in the stretched state, and the pulling assembly 3 applies a certain elastic restoring force to the rotating bracket 31 and the second frame 22. Under the action of an external force, the first frame body 21 and the second frame body 22 have a tendency of relative translation, and the elastic restoring force of the pulling assembly 3 in a stretching state can counteract the external force, so that the first frame body 21 and the second frame body 22 are ensured not to generate relative translation along the rotating shaft L1.

In this application, through setting up pulling assembly 3, and the crossing setting of the axis that sets up at least one elastic extensible member 32's flexible direction and second framework 22, thereby receive under the effect of external force at first framework 21 and second framework 22, the elastic restoring force of the elastic extensible member 32 that is in the tensile state can offset whole or partial external force, thereby avoid or reduce the relative translation of first framework 21 and second framework 22 along pivot L1 direction that causes because external force to a certain extent, avoid electronic equipment 100 to produce unrecoverable deformation in the articulated department of first framework 21 and second framework 22, improve the stability of first framework 21 and second framework 22 along pivot L1 relative rotation, improve electronic equipment 100's quality.

The first frame body 21 and the second frame body 22 may have an approximately rectangular outer shape. The rotating bracket 31 may be disposed on a side of the first frame 21 facing away from the display screen 1. Optionally, a side of the first frame 21 away from the display screen 1 has a mounting protrusion, and the rotating bracket 31 is connected to the mounting protrusion, so as to connect the rotating bracket 31 to the first frame 21.

The first elastic expansion element 321 and the second elastic expansion element 322 may or may not have the same structure, but both have elastic stretching property. The stretching direction of at least one of the first elastic stretching member 321 and the second elastic stretching member 322 intersects with the central axis L2 of the second frame 22, and certainly, the stretching direction of the first elastic stretching member 321, the stretching direction of the second elastic stretching member 322, and the rotating shaft L1 may intersect with each other. The first elastic expansion piece 321 and the second elastic expansion piece 322 are arranged, so that the limiting capacity of the pulling assembly 3 is improved.

In one embodiment, the first resilient telescoping member 321 and the second resilient telescoping member 322 intersect. When the second frame 22 is acted by an external force along the first direction X and generates a translation trend parallel to the rotation axis L1, the first elastic expansion member 321 contracts, the second elastic expansion member 322 stretches, and the second elastic expansion member 322 can drive the rotating bracket 31 to rotate relative to the first frame 21, so that the rotating bracket 31 rotates, the stretching length of the second elastic expansion member 322 is reduced, and the stretching length of the first elastic expansion member 321 is increased, so that the stretched first elastic expansion member 321 can also apply an elastic restoring force to the shell 2, and the elastic restoring force can be used for offsetting the external force, thereby limiting the first frame 21 and the second frame 22 from translating along the rotation axis L1; when the second frame 22 receives the external force action along deviating from the first direction X and generates the translation trend parallel to the rotation axis L1, the second elastic expansion piece 322 contracts, the first elastic expansion piece 321 stretches, the first elastic expansion piece 321 can drive the rotation support 31 to rotate relative to the first frame 21, thereby rotating through the rotation support 31, reduce the stretching length of the first elastic expansion piece 321, and increase the stretching length of the second elastic expansion piece 322, so that the stretched second elastic expansion piece 322 can also apply the elastic restoring force to the shell 2, the elastic restoring force can be used for offsetting the external force, thereby limiting the first frame 21 and the second frame 22 from translating along the rotation axis L1.

The greater the distance interval, the greater the range of the rotating bracket 31 to adjust the relative stretching lengths of the first elastic expansion member 321 and the second elastic expansion member 322.

In some embodiments, one end of the first elastic expansion element 321 and the second elastic expansion element 322 are symmetrically disposed with respect to the central axis L2, so that the elastic deformation force required by the first elastic expansion element 321 and the second elastic expansion element 322 can be conveniently calculated, and the first elastic expansion element 321 and the second elastic expansion element 322 can both achieve a better limiting effect under the action of external force in opposite directions. Alternatively, the pulling member 3 is disposed symmetrically about the central axis L2 in the unfolded state of the electronic device 100. In the folded state of the electronic device 100, since the flexible portions of the first elastic expansion element 321 and the second elastic expansion element 322 may be randomly bent, only the rigid portions of the first elastic expansion element 321 and the second elastic expansion element 322 are symmetrically disposed about the central axis L2.

In some embodiments, the second frame 221 includes a first side 22a and a second side 22b opposite to each other along the extending direction of the rotation axis L1, and further includes a first fixing member 222 and a second fixing member 223, the first fixing member 222 is connected to the first side 22a, the second fixing member 223 is connected to the second side 22b, the first elastic expansion member 321 is connected to the first fixing member 222, and the second elastic expansion member 322 is connected to the second fixing member 223.
