Description

Technical Field

[0001] The present invention relates to the technical field of electronic equipment, and in particular to an electronic equipment. Background Art

[0002] With the improvement of user demand and the development of technology, the screens of electronic devices are getting bigger and bigger. In order to take into account the large screen and the portability of electronic devices, electronic devices equipped with scroll screens are gradually favored by users. In order to adaptively support the flexible screen, the electronic devices involved in the related technology adopt two comb teeth structures that can move relatively.

[0003] The two comb-tooth structures that cooperate with each other will cause severe friction when the flexible screen is expanded or contracted, which will cause abnormal noise, which will undoubtedly affect the user's use. Summary of the invention

[0004] The present invention discloses an electronic device to solve the problem in the related art that when the electronic device uses two relatively movable comb-tooth structures to support a flexible screen, the comb-tooth structures have serious friction during the process of the flexible screen being unfolded or retracted, which in turn causes abnormal noise.

[0005] In order to solve the above-mentioned technical problems, the present invention is achieved as follows:

[0006] The present invention discloses an electronic device, comprising a first body, a second body, a telescopic component and a flexible display screen, wherein the flexible display screen is connected to the first body and the second body, the second body is connected to the first body through the telescopic component, the second body is movably arranged on the first body, and the moving direction of the second body is parallel to the telescopic direction of the telescopic component;

[0007] When the electronic device is in an unfolded state, the telescopic component is extended, and the second body and the telescopic component jointly support the flexible display screen;

[0008] When the electronic device is in a folded state, the telescopic assembly is shortened, and among the second body and the telescopic assembly, at least the second body supports the flexible display screen.

[0009] The technical solution adopted by the present invention can achieve the following technical effects:

[0010] The electronic device disclosed in the embodiment of the present application is provided with a telescopic component, so that the telescopic component can be connected between the first body and the second body, so that when the second body moves relative to the first body, the telescopic component can be extended and retracted, so that when the electronic device is in the unfolded state, the telescopic component is extended, and the second body and the telescopic component jointly support the flexible display screen, and when the electronic device is in the folded state, the telescopic component is shortened. Among the second body and the telescopic component, at least the second body supports the flexible display screen, so that the flexible display screen can be better supported in both the unfolded state and the folded state through the extension and retraction of the telescopic component, thereby replacing the method in the related art where the electronic device uses two relatively movable comb tooth structures to support the flexible display screen, and it is easier to achieve by setting fewer telescopic components. Compared with the cooperation between dense comb tooth structures, the telescopic component is easier to form a structure with a smaller contact area with the flexible display screen, thereby forming a smaller contact area, thereby solving the problem that when the electronic device in the related art uses two relatively movable comb tooth structures to support the flexible screen, the comb tooth structure has relatively serious friction during the unfolding or contraction of the flexible screen, thereby causing abnormal noise.

[0053] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the specific embodiments of the present invention and the corresponding drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0054] The technical solutions disclosed in various embodiments of the present invention are described in detail below in conjunction with the accompanying drawings.

[0055] Please refer to Figures 1 to 31 The embodiment of the present invention discloses an electronic device, which may be a mobile phone, a tablet, a game console, etc. The disclosed electronic device includes a first body 100, a second body 200, a telescopic component 300 and a flexible display screen 400.

[0056] The first body 100 and the second body 200 can be the basis for installing other components of the electronic device. The second body 200 is movably arranged on the first body 100. The second body 200 moves relative to the first body 100 to switch the electronic device between an extended state and a folded state.

[0057] The flexible display screen 400 is a component for displaying the screen of the electronic device. The flexible display screen 400 is connected to the first body 100 and the second body 200. The second body 200 is connected to the first body 100 through the telescopic component 300, and the second body 200 is movably arranged on the first body 100. When the second body 200 moves relative to the first body 100, the moving direction of the second body 200 is parallel to the telescopic direction of the telescopic component 300, and the telescopic component 300 can be telescoped according to the movement of the second body 200.

[0058] When the electronic device is in the unfolded state, the telescopic component 300 is extended, and the second body 200 and the telescopic component 300 jointly support the flexible display screen 400. When the electronic device is in the collapsed state, the telescopic component 300 is shortened, and among the second body 200 and the telescopic component 300, at least the second body 200 supports the flexible display screen 400.

[0059] Specifically, when the second body 200 is a comb-tooth structure, when the electronic device is in a folded state, the telescopic component 300 is shortened, and the flexible display screen 400 can be supported only by the second body 200, or the second body 200 and the telescopic component 300 can support the flexible display screen 400 together, and the telescopic component 300 in a shortened state can be located between the teeth of the comb-tooth structure, and the telescopic component 300 and the second body 200 can support the flexible display screen together. When the second body 200 is a complete planar structure, the flexible display screen 400 can be supported only by the second body 200.

[0060] In a specific implementation process, during the gradual unfolding of the electronic device, the second body 200 moves relative to the first body 100, and the second body 200 can drive the telescopic component 300 to stretch, so that the telescopic component 300 is extended. When the electronic device is unfolded to the unfolded state, the second body 200 and the telescopic component 300 jointly support the flexible display screen 400. During the gradual folding of the electronic device, the second body 200 can push the telescopic component 300 to shorten. When the electronic device is folded to the folded state, among the second body 200 and the telescopic component 300, at least the second body 200 supports the flexible display screen 400. Of course, the telescopic component 300 may not be extended by the second body 200, but may be extended by providing a separate driving member.

[0061] The electronic device disclosed in the embodiment of the present application is provided with a telescopic component 300, so that the telescopic component 300 can be connected between the first body 100 and the second body 200, so that when the second body 200 moves relative to the first body 100, the telescopic component 300 can be extended, and then when the electronic device is in the unfolded state, the telescopic component 300 is extended, and the second body 200 and the telescopic component 300 jointly support the flexible display screen 400, and when the electronic device is in the folded state, the telescopic component 300 is shortened, and among the second body 200 and the telescopic component 300, at least the second body 200 supports the flexible display screen, so that the flexible display screen can be extended by the extension of the telescopic component 300. The flexible display screen 400 can be well supported in both the expanded state and the collapsed state, thus replacing the method in the related art where the electronic device uses two relatively movable comb-tooth structures to support the flexible display screen. It is easier to achieve this by setting up fewer telescopic components. Compared with the cooperation between dense comb-tooth structures, the telescopic components are easier to form a structure with a smaller contact area with the flexible display screen, thereby forming a smaller contact area, thereby solving the problem that when the electronic device in the related art uses two relatively movable comb-tooth structures to support the flexible screen, the comb-tooth structure has severe friction during the expansion or contraction of the flexible screen, which in turn causes abnormal noise.

[0062] In an optional embodiment, the telescopic assembly 300 may include a first pull rod 310, a second pull rod 320 and a third body 330. The first pull rod 310 may be connected between the second body 200 and the third body 330, the second pull rod 320 may be connected between the third body 330 and the first body 100, and both the first pull rod 310 and the second pull rod 320 may be slidably connected to the third body 330 and may slide in the telescopic direction.

[0063] Specifically, the third body 330 may be provided with a slide groove, and the first pull rod 310 and the second pull rod 320 may be slidably arranged in the slide groove. Of course, the third body 330 may also be equipped with a slide rail, and the first pull rod 310 and the second pull rod 320 may slide with the slide rail. When the telescopic assembly 300 is shortened, the first pull rod 310 and the second pull rod 320 may slide to a position overlapping with the third body 330, and when the telescopic assembly 300 is extended, at least a portion of at least one of the first pull rod 310 and the second pull rod 320 may slide to a position misaligned with the third body 330. The misalignment of the first pull rod 310, the second pull rod 320 and the third body 330 means that the first pull rod 310, the second pull rod 320 and the third body 330 do not overlap at least partially in the overlapping direction.

[0064] The electronic device may have a first unfolded state and a second unfolded state. In the process of gradually unfolding the electronic device, the first rod 310 may first slide with the first body 100 relative to the third body 330 to extend the telescopic assembly 300, and the electronic device may be in the first unfolded state, and then the second rod 320 may slide relative to the third body 330 to further extend the telescopic assembly 300, and the electronic device may be in the second unfolded state. Of course, in some other embodiments, the first rod 310 and the second rod 320 may slide relative to the third body 330 together, and the electronic device may be in the first unfolded state or the second unfolded state.

[0065] In other embodiments, the first body 100 may first move relative to the telescopic component 300. When the first body 100 moves to a position where it is in limited contact with the telescopic component 300 in the extension direction, the electronic device may be considered to be in the first unfolded state. The first body 100 then slides to drive the telescopic component 300 to extend until the telescopic component 300 extends to a maximum length. At this time, the electronic device may be considered to be in the second unfolded state.

[0066] When the electronic device is in the unfolded state, the second body 200, the first rod 310, the second rod 320 and the third body 330 may jointly support the flexible display screen 400. When the electronic device is not fully unfolded, at least one or part of the first rod 310 and the second rod 320 may jointly support the flexible display screen 400 with the second body 200 and the third body 330. When the electronic device is in the folded state, the second body 200 and the third body 330 may jointly support the flexible display screen 400. For example, in the first unfolded state, the first rod 310 and the third body 330 may jointly support the flexible display screen 400, and in the second unfolded state, the first rod 310, the second rod 320 and the third body 330 may jointly support the flexible display screen 300.

[0067] In the embodiment of the present application, the telescopic assembly 300 is configured to include a first pull rod 310, a second pull rod 320, and a third body 330, so that the first pull rod 310 can be connected between the second body 200 and the third body 330, the second pull rod 320 can be connected between the third body 330 and the first body 100, and the first pull rod 310 and the second pull rod 320 can be slidably connected to the third body 330 and can slide in the telescopic direction, so that the telescopic assembly 300 can adapt to different unfolding states of the electronic device, so that the electronic device can be better supported in different unfolding states.

[0069] In the embodiment of the present application, a first slide groove 331 extending along the extension direction is provided on the side of the third body 330 facing away from the flexible display screen 400, and a first limiting protrusion 332 is provided on the port of the first slide groove 331 adjacent to the second body 200, so that the first pull rod 310 can slide and cooperate with the first slide groove 331 in the extension direction, so that the first slide groove 331 can guide and limit the first pull rod 310, so that the sliding of the first pull rod 310 relative to the third body 330 is more stable and can avoid falling off.

[0070] In an optional embodiment, a second slide groove 333 extending in the telescopic direction may be provided on a side of the third body 330 facing away from the flexible display screen 400, a first end of the second pull rod 320 may pass through a first port of the second slide groove 333, and be connected to the first body 100, and the second pull rod 320 may be disposed in the second slide groove 333 and slidably cooperate with the second slide groove 333. Specifically, a limiting protrusion may be provided at the second end of the second pull rod 320 and the first port of the second slide groove 333, respectively, to limit the second pull rod 320 from sliding out of the second slide groove 333.

[0071] In the embodiment of the present application, a second slide groove 333 extending along the telescopic direction is set on the side of the third body 330 facing away from the flexible display screen 400. The first end of the second pull rod 320 can pass through the first port of the second slide groove 333 and be connected to the first body 100, so that the second pull rod 320 can be set in the second slide groove 333 and slidably cooperate with the second slide groove 333, thereby making the sliding of the second pull rod 320 relative to the third body 330 more stable and avoiding falling off.

[0072] Optionally, a third slide groove 334 extending in the telescopic direction may be provided on one side of the third body 330 facing away from the flexible display screen 400. The electronic device may include a guide rail seat 510 and a first guide rail 520 movably provided on the guide rail seat 510, the guide rail seat 510 may be fixed to the first body 100, the first guide rail 520 may be connected to the second body 200, and the first guide rail 520 may be slidably matched with the third slide groove 334. The surface of the third slide groove 334 where the port facing the second body 200 is located may be a limiting end surface, and when the electronic device is in the unfolded state, the guide rail seat 510 may be in limiting contact with the limiting end surface in the extension direction of the telescopic assembly 300.

[0073] In the embodiment of the present application, by setting the guide rail seat 510 and the first guide rail 520, the side of the third body 330 facing away from the flexible display screen 400 can be provided with a third slide groove 334 extending in the telescopic direction, so that the guide rail seat 510 can be fixed to the first body 100, the first guide rail 520 can be connected to the second body 200, and the first guide rail 520 can slide with the third slide groove 334, so that the second body 200 is more stable when moving relative to the first body 100, and the surface of the port of the third slide groove 334 facing the second body 200 can be a limiting end face. When the electronic device is in the unfolded state, the guide rail seat 510 can be in limited contact with the limiting end face in the elongation direction of the telescopic component 300, so that the electronic device is kept in the unfolded state to avoid unlimited stretching. In this case, the guide rail seat 510 not only plays a guiding function, but also plays a limiting function, achieving the purpose of dual use of one object.

[0074] Optionally, the electronic device may include a slide rail assembly 500, and the slide rail assembly 500 may be connected between the first body 100 and the second body 200, and the first body 100 and the second body 200 may move relative to each other through the slide rail assembly 500.

[0076] By providing a plurality of first and second rods 310 and 320 , the electronic device can support the flexible display screen 400 by the plurality of first and second rods 310 and 320 when in the unfolded state, thereby providing better support for the flexible display screen 400 .

[0077] In an optional embodiment, the telescopic assembly 300 may include a plurality of tie rod assemblies 340, the plurality of tie rod assemblies 340 may be spaced apart, and the tie rod assemblies 340 may be connected between the first body 100 and the second body 200, wherein: when the electronic device is in the unfolded state, the plurality of tie rod assemblies 340 may be extended, and the second body 200 and the plurality of tie rod assemblies 340 may jointly support the flexible display screen 400. When the electronic device is in the folded state, the plurality of tie rod assemblies 340 may be shortened, and the second body 200 and the plurality of tie rod assemblies 340 may jointly support the flexible display screen 400.

[0079] In an optional embodiment, the rod assembly 340 may include a third rod 341, a fourth rod 342, and a fifth rod 343. The third rod 341 may be provided with a fourth slide groove 341a, the fourth rod 342 may be provided with a fifth slide groove 342a, the first end of the third rod 341 may be connected to the second body 200, the second end of the third rod 341 may be provided with a notch communicating with the fourth slide groove 341a, the first end of the fourth rod 342 may extend from the notch into the fourth slide groove 341a, and slide with the fourth slide groove 341a, the first end of the fifth rod 343 may extend into the fifth slide groove 342a, and the second end of the fifth rod 343 may be connected to the first body 100.

The second body 200 continues to move and can push the fourth rod 342 to move so that the fifth rod 343 is retracted into the fifth slot 342a. Of course, when the electronic device is folded, the fifth rod 343 can be retracted into the fifth slot 342a first, and then the fourth rod 342 can be retracted into the fourth slot 341a, or the fourth rod 342 and the fifth rod 343 can be retracted together.

[0081] In the embodiment of the present application, the rod assembly 340 is configured to include a third rod 341, a fourth rod 342 and a fifth rod 343, so that the rod assembly 340 can adapt to different unfolding states of the electronic device, thereby enabling the flexible display screen 400 of the electronic device to be better supported in different unfolding states.

[0082] Optionally, the pull rod assembly 340 may also be two rods or four rods slidably connected to achieve extension or shortening, and the specific structure of the pull rod assembly 340 is not limited here.

The driving motor 611 is connected to the reduction gear module 612, and the screw rod 613 is connected to the reduction gear module 612. After the power of the driving motor 611 is output, it is reduced to a constant speed through the reduction gear module 612 and transmitted to the screw rod 613. The pushing block 616 is sleeved on the screw rod 613 and is threadedly matched with the screw rod 613. The rotation of the screw rod 613 can drive the pushing block 616 to move along the axial direction of the screw rod 613. The light rod 614 can be arranged on both sides of the screw rod 613 and arranged parallel to the screw rod 613. The pushing block 616 can be provided with a through hole for the light rod 614 to pass through. The light rod 614 is used to guide and stabilize the movement of the pushing block 616. The rotating bearing 615 is installed at the ends of the screw rod 613 and the polished rod 614, and the pushing block 616 is fixed to the first body by the locking member 617. The driving motor 611, the reduction gear module 612, the screw rod 613, the polished rod 614, the rotating bearing 615, and the pushing block 616 are all installed on the module bracket 618. After the reduction gear module 612 is installed on the module bracket 618, the gear cover 619 and the module bracket 618 encapsulate the reduction gear module 612. The flexible circuit board 620 is used to connect between the driving motor 611 and the power supply to provide power to the driving motor 611.
