DETAILED DESCRIPTION

[0048] The exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided in order to enable a more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.

[0049] It should be noted that, unless otherwise specified, the technical terms or scientific terms used in this application should have the common meanings understood by technicians in the field to which this application belongs.

[0050] The technical solution of the embodiment of the present application is to solve the above technical problems, and the overall idea is as follows:

[0051] Reference Figure 1 and attached Figure 2 The electronic device provided by the embodiment of the present application comprises, in a specific implementation, a movable part 3, a buffer component 4, and a first body 1 and a second body 2 connected in rotation, wherein the second body 2 comprises a first sub-body 21 and a second sub-body 22 connected in relative motion along a first direction a; the first direction a is perpendicular to the rotation axis of the first body 1 and the second body 2; the movable part 3 can reciprocate along the first direction a relative to the first sub-body 21 under the driving force; the buffer component 4 is connected to the movable part 3, and the buffer component 4 is connected to the second sub-body 22, so as to cooperate with the movable part 3 to drive the second sub-body 22 to approach or move away from the first sub-body 21 along the first direction a;

[0052] When the movable portion 3 reciprocates along the first direction a, the buffer assembly 4 can provide compressible displacement in the first direction a.

[0053] Specifically, in order to solve the problem that when the screen end rises, the reverse external force will make the transmission structure unable to achieve the jacking effect of the screen end, but the jacking force is not eliminated, which will lead to damage to the transmission structure and shorten the service life of the overall equipment, the electronic device provided in this embodiment is equipped with a movable part 3 and a buffer component 4, so that when the movable part 3 drives the second sub-body 22 to move relative to the first sub-body 21 along the first direction a, once there is a force in the opposite direction of the first direction a that affects the movement of the movable part 3, such as performing a drop test of the equipment or manually pressing the second sub-body 22 to prevent its movement; the buffer component 4 can absorb the reverse force and even the reverse displacement through compressible displacement, thereby ensuring that the movable part 3 can maintain the original movement direction and original movement trend, and avoiding the movement of the movable part 3 from being blocked or even damaged.

[0054] Among them, the electronic device provided in this embodiment can be, but is not limited to, a laptop computer capable of screen stretching, the first body 1 is the system end, the second body 2 is the screen end, the first body 1 can be provided with a traditional keyboard key 11 and a touch area 12, or a display screen can be provided, and the second body 2 is provided with a flexible screen (not shown in the figure), and the size of the flexible screen can be adjusted as needed to match the usage scenarios of different display screens. Accordingly, the second body 2 includes a first sub-body 21 and a second sub-body 22, and the first sub-body 21 and the second sub-body 22 are connected in a sliding manner along a first direction a, so that the flexible screen can be stretched or contracted during the relative sliding process to adjust the display area; it can be understood that the first sub-body 21 and the second sub-body 22 are both rigid structures, the first sub-body 21 is rotatably connected to the first body 1, and the second sub-body 22 serves as the outer shell of the second body 2.

[0055] The movable part 3 is a rigid structure, which may be, but is not limited to, a nut, a slider, etc. The movable part 3 may be arranged in conjunction with a screw to receive a driving force, and the movable part 3 transmits the driving force to the second sub-body 22 so that the second sub-body 22 can move away from or approach the first sub-body 21. Figure 5 In this embodiment, a connecting member 5, a driving screw 6 and a guide rod 7 are provided, which include a first frame 51, a second frame 52 and a third frame 53; the first frame 51 and the second frame 52 are arranged at intervals along the first direction a, and the two ends of the third frame 53 are respectively connected to the first frame 51 and the second frame 52 to form a C-shaped or U-shaped frame as a mounting structure for the driving screw 6 and the guide rod 7. In this embodiment, a fourth frame 54 can also be provided to cooperate with the third frame 53 to form a rectangular frame to improve stability; the driving screw 6 and the guide rod 7 are arranged at intervals along the second direction b and are all along the The first direction a extends; the second direction b is perpendicular to the first direction a, that is, the length direction of the second body 2 in practice; wherein, the movable part 3 is provided with a first through hole and a second through hole at the same time, the inner wall of the first through hole is provided with a thread to be sleeved on the driving screw 6, and the second through hole is sleeved on the guide rod 7; so that the driving screw 6 rotates around the first direction a after receiving the rotational driving force so that the movable part can reciprocate along the driving screw 6, and the guide rod 7 ensures the stable movement of the movable part 3 to avoid deviation; of course, the number of the driving screw 6 and the guide rod 7 can be adjusted according to actual needs and the space design in the actual device. Accordingly, the connection between the movable part 3 and the second sub-body 22 can be realized by the buffer assembly 4, that is, the movable part 3 is not directly connected to the second sub-body 22, and then when the second sub-body 22 is subjected to the reverse force in the first direction a, it will not directly act on the movable part 3, but on the buffer assembly 4. Of course, the driving motor or motor of the driving screw 6 is also provided by the electronic device provided in this embodiment.

[0056] Among them, the buffer component 4 is at least partially elastic and can produce compressible displacement. In this embodiment, the buffer component 4 is directly connected to the second sub-body 22. The movable part 3 and the buffer component 4 can be connected or movably connected. The movable part 3 can transmit the movement force to the buffer component 4 to drive the second sub-body 22 to move. Furthermore, the buffer component 4 is provided with a third through hole and the fourth through hole, which are respectively sleeved on the driving screw 6 and the guide rod 7 to achieve cooperation with the movable part 3.

[0057] According to the above, the electronic device provided in the first aspect of the present application is provided with a buffer component 4 in conjunction with the movable part 3, so that when the movable part 3 moves along the first direction a, the driving force can be transmitted to the buffer component 4 through the compression displacement of the buffer component 4 to achieve the lifting or retraction of the second sub-body 22 relative to the first sub-body 21, and then when the movable part 3 is lifting, if the second sub-body 22 is subjected to a force opposite to the first direction a, the buffer component 4 will absorb the external force by generating a compression displacement close to the movable part 3, while the movable part 3 can still maintain its original state of motion, thereby avoiding damage to the movable part 3; thereby solving the problem that when the screen end rises, it is subjected to a reverse external force, which will make the transmission structure unable to achieve the lifting effect of the screen end, but the lifting force is not eliminated, thereby causing damage to the transmission structure and shortening the service life of the overall equipment.

[0058] The term "and / or" in this article is merely a description of the association relationship of associated objects, indicating that three relationships may exist, for example, A and / or B, which is specifically understood as: A and B may be included at the same time, A may exist alone, or B may exist alone, and any of the above three situations may exist.

In this arrangement, two ends of the first elastic member 42 are connected to the first buffer frame 41 and the movable portion 3 respectively, which may be in the form of hooking or bonding, but is not limited to it.

The first buffer frame 43 and the second buffer frame 42 are respectively arranged on both sides of the movable part 3, and are respectively matched with an elastic member, so that no matter whether the movable part 3 moves forward or backward along the first direction a, the flexibility and reaction rate of the bracket structure along the first direction a can be improved by squeezing one elastic member and stretching the other elastic member; and under this arrangement, the two ends of the first elastic member 42 and the second elastic member 44 can remain in a free state, and only need to contact with the movable part 3 and the bracket, without hooking or bonding.
