Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of communication equipment, and particularly relates to an electronic device. BACKGROUND

[0002] With the improvement of user demand, the performance of electronic devices is continuously optimized. Among them, the display performance of electronic devices is becoming more and more powerful.

[0003] The electronic device involved in the related art is configured with a flexible screen. The flexible screen can present a larger display interface following the stretching of the electronic device. When the user needs a smaller display interface, the flexible screen can at least partially retract into the electronic device following the contraction of the electronic device. Such an electronic device can realize the size switching of the display interface, which facilitates the use of the user.

[0004] In the related art, the electronic device includes a first screen support, a second screen support and a flexible screen. The first screen support and the second screen support are used to support the flexible screen. The first screen support and the second screen support are movably coupled to switch the electronic device between a folded state and an unfolded state, so as to make the flexible screen unfold or fold.

[0005] However, in the process of unfolding the flexible screen of the electronic device, there is a large gap between the first screen support and the second screen support. The flexible screen corresponding to the gap is in a suspended state. Therefore, the strength of the flexible screen at the gap is poor and is easily damaged by extrusion. Therefore, the safety and reliability of the electronic device are poor. SUMMARY

[0006] The purpose of the embodiments of the application is to provide an electronic device that can solve the problem of poor safety and reliability of the electronic device.

[0007] In order to solve the above technical problems, the application is implemented as follows:

[0008] The embodiments of the application provide an electronic device, which includes a first screen support, a second screen support, a flexible screen and a support part.

[0009] The flexible screen is arranged on the first screen support and the second screen support. The first screen support and the second screen support are movably coupled to switch the electronic device between a folded state and an unfolded state.

[0010] At least one of the first screen support and the second screen support is provided with a receiving groove.

[0011] In the case that the electronic device is in the folded state, the support part is received in the receiving groove.

[0012] In the case that the electronic device is in the unfolded state, at least part of the support portion extends out of the accommodating groove, and at least part of the support portion fills in the gap formed by the first screen support and the second screen support to support the flexible screen.

[0013] In the embodiments of the present application, at least one of the first screen support and the second screen support is provided with an accommodating groove. In the case that the electronic device is in the folded state, the support portion is accommodated in the accommodating groove; in the case that the electronic device is in the unfolded state, at least part of the support portion extends out of the accommodating groove, and at least part of the support portion fills in the gap formed by the first screen support and the second screen support to support the flexible screen. In this scheme, when the electronic device is in the unfolded state, the support portion can fill in the gap formed by the first screen support and the second screen support due to unfolding, thereby supporting the flexible screen, reducing the area of the flexible screen in suspension, thereby playing a better supporting role, so that the flexible screen is not easily damaged, thereby improving the safety and reliability of the electronic device.

DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present application will be clearly described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the scope of protection of the present application.

[0022] The terms "first", "second", and the like in the specification and claims of the present application are used to distinguish similar objects, and are not used to describe a specific order or sequence. It should be understood that the data used in this way can be interchanged under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described herein. In addition, "and / or" in the specification and claims indicates at least one of the connected objects, and the character " / ", generally indicates that the front and rear associated objects are in a "or" relationship.

[0023] The electronic device provided by the embodiments of the present application will be described in detail below with reference to the drawings and specific embodiments and their application scenarios.

[0024] Please refer to Figures 1 to 9 The electronic device disclosed by the embodiments of the present application includes a first screen support 110, a second screen support 120, a flexible screen, and a support part 200.

[0025] The flexible screen is arranged on the first screen support 110 and the second screen support 120, and the first screen support 110 and the second screen support 120 are used to support the flexible screen. The first screen support 110 and the second screen support 120 are movably matched to switch the electronic device between a folded state and an unfolded state.

[0026] Specifically, the first screen support 110 and the second screen support 120 can move away from each other, and thus the electronic device is gradually unfolded until the unfolded state, at which the flexible screen is stretched and unfolded along with the movement of the first screen support 110 and the second screen support 120 away from each other, so as to increase the display interface of the electronic device. The first screen support 110 and the second screen support 120 can move close to each other, and thus the electronic device is gradually folded until the folded state, at which the flexible screen is rolled and retracted along with the movement of the first screen support 110 and the second screen support 120 close to each other, so as to decrease the display interface of the electronic device.

[0027] At least one of the first screen support 110 and the second screen support 120 is provided with a receiving groove 101. In the case that the electronic device is in the folded state, the support part 200 is received in the receiving groove 101. In the case that the electronic device is in the unfolded state, at least part of the support part 200 extends out of the receiving groove 101, and at least part of the support part 200 fills in the gap formed by the first screen support 110 and the second screen support 120, so as to support the flexible screen.

[0028] Specifically, in the working process, when the electronic device is in the folded state, the first screen support 110 and the second screen support 120 are close to each other, and thus the gap formed by the first screen support 110 and the second screen support 120 is very small, and thus the overhanging area of the flexible screen is very small, which does not affect the display performance of the flexible screen and the strength of the flexible screen. When the electronic device is in the unfolded state, the first screen support 110 and the second screen support 120 move relatively, and at least part of the support part 200 also extends out of the receiving groove 101 to fill in the gap formed by the first screen support 110 and the second screen support 120 due to unfolding. The gap between the first screen support 110 and the second screen support 120 is filled by the support part 200, and thus the support part 200 can support the flexible screen when the electronic device is in the unfolded state.

[0029] Optionally, the support part 200 can be elastic foam, which is extruded in the receiving groove 101 when the electronic device is in the folded state, and which is extruded out to support the flexible screen when the electronic device is in the unfolded state. Of course, the support part 200 can also be two springs with perpendicular elastic directions, one of which is used to drive the other elastic member to extend out of the receiving groove 101 along the movement direction of the first screen support 110, and the other spring is elongated when extending out of the receiving groove 101, so as to support the flexible screen. Of course, the support part 200 is not limited to the above two ways, and can also be other structures, which are not limited herein.

[0030] In the embodiments disclosed in the present application, when the electronic device is in the unfolded state, at least part of the support part 200 can fill the gap formed by the unfolding of the first screen support 110 and the second screen support 120, thereby supporting the flexible screen, reducing the area of the flexible screen in suspension, thereby providing better support, so that the flexible screen is not easily damaged, thereby improving the safety and reliability of the electronic device.

[0031] In addition, in the related art, the flexible screen has a large suspended area, so the flexible screen is prone to sagging, thereby causing the flexible screen to have a concave-convex touch, and thus the user experience and appearance performance of the electronic device are poor. In the embodiments disclosed in the present application, the support part 200 can fill the gap formed by the unfolding of the first screen support 110 and the second screen support 120, thereby supporting the flexible screen, reducing the area of the flexible screen in suspension, so the support surface of the flexible screen is larger, so the flexible screen is not prone to sagging, thereby improving the user experience and appearance performance of the electronic device.

[0032] In the above embodiments, the extension of the support part 200 out of the accommodation groove 101 can be achieved by driving the motor, however, the driving motor consumes a lot of energy and the circuit structure is complex.

[0033] Therefore, in another alternative embodiment, the support part 200 can include a first elastic member 210 and a telescopic body 220, the extension direction of the first elastic member 210 is parallel to the movement direction of the first screen support 110, one end of the first elastic member 210 abuts against the first screen support 110 or the second screen support 120, and the other end of the first elastic member 210 abuts against the telescopic body 220. The first elastic member 210 can drive the telescopic body 220 to extend out of the accommodation groove 101 in the extension direction of the first elastic member 210, and the telescopic body 220 can be elongated or shortened in the direction of approaching or moving away from the flexible screen. The first elastic member 210 drives the telescopic body 220 to extend out of the accommodation groove 101 in the movement direction of the first screen support 110, so the extension direction of the slot opening to the slot bottom of the accommodation groove 101 is parallel to the movement direction of the first screen support 110.

[0034] In the case where the electronic device is in the folded state, the telescopic body 220 is shortened and located in the accommodation groove 101. At this time, the first screen support 110 and the second screen support 120 block the telescopic body 220, so that the first elastic member 210 is compressed, thereby making the telescopic body 220 located in the accommodation groove 101.

[0035] In the case that the electronic device is in the unfolded state, the first elastic member 210 can drive the telescopic body 220 to extend out of the accommodation groove 101, and the telescopic body 220 is elongated to support the flexible screen. At this time, in the process of unfolding the electronic device, the first screen support 110 or the second screen support 120 removes the resistance, so that the first elastic member 210 restores the deformation, and drives the telescopic body 220 out of the accommodation groove 101. It can also be understood that when the first screen support 110 moves relative to the second screen support 120, the first elastic member 210 is elongated and restored to the deformation. In the process of elongating the first elastic member 210, the first elastic member 210 exerts pressure on the telescopic body 220, so that the relative position of the telescopic body 220 does not change, and the first screen support 110 or the second screen support 120 moves relative to the telescopic body 220, so that at least part of the telescopic body 220 extends out of the accommodation groove 101.

[0036] In the specific working process, when the electronic device is switched from the folded state to the unfolded state, the first elastic member 210 is in a compressed state. In the process of unfolding the electronic device, the first screen support 110 or the second screen support 120 removes the resistance, so that the first elastic member 210 restores the deformation and drives the telescopic body 220 out of the accommodation groove 101. When the electronic device is switched from the unfolded state to the folded state, the first screen support 110 or the second screen support 120 moves and exerts pressure on the telescopic body 220, so that the first elastic member 210 is retracted to compress the telescopic body 220 and the first elastic member 210, and is recovered into the accommodation groove 101.

[0037] In this scheme, the first elastic member 210 is retracted by the reaction force of the first screen support 110 or the second screen support 120. The telescopic body 220 is driven to extend out of the accommodation groove 101 by the elastic force of the first elastic member 210. Compared with the motor-driven mode, the support part 200 disclosed in the application has small energy consumption and simple structure.

[0038] In the above embodiment, the first elastic member 210 can be a spring, elastic rubber or elastic foam, and of course can also be other elastic structures, which are not limited herein.

[0039] In the above embodiment, the telescopic body 220 can be a telescopic motor or a telescopic cylinder. However, the telescopic motor and the telescopic cylinder have complex structures and high costs.

[0040] Based on this, in another alternative embodiment, the telescopic body 220 can include a telescopic frame 221, which can include a first support edge 2211, a second support edge 2212, and a plurality of rotating edges. The first support edge 2211 and the second support edge 2212 can be arranged in a spaced-apart manner along the direction in which the telescopic body 220 approaches or moves away from the flexible screen. The first support edge 2211 and the second support edge 2212 can be oppositely arranged. At this time, when the telescopic body 220 is located outside the accommodation groove 101, the first support edge 2211 or the second support edge 2212 is used to support the flexible screen. The opposite sides of the first support edge 2211 and the second support edge 2212 are both provided with a plurality of rotating edges, and the same side of the first support edge 2211 and the second support edge 2212 is connected through a plurality of rotating edges that are sequentially hinged. The first support edge 2211 and the second support edge 2212 are hinged with the rotating edges connected thereto. At this time, the first support edge 2211, the second support edge 2212, and the rotating edges form a polygonal structure.

[0041] In the case where the electronic device is in the folded state, the distance between the first support edge 2211 and the second support edge 2212 is a first distance; in the case where the electronic device is in the unfolded state, the distance between the first support edge 2211 and the second support edge 2212 is a second distance. The first distance can be less than the second distance.

[0042] In a specific embodiment, when the electronic device is switched from the folded state to the unfolded state, part of the telescopic body 220 extends out of the accommodation groove 101, and the rotating edges on both sides of the first support edge 2211 and the second support edge 2212 rotate relative to each other. At this time, the distance between the first support edge 2211 and the second support edge 2212 increases, so as to elongate the telescopic frame 221. At this time, when the arrangement direction of the first support edge 2211 and the second support edge 2212 can be the length direction of the telescopic frame 221, the plurality of rotating edges are distributed along the opposite sides of the width direction of the telescopic frame 221. The first support edge 2211 and the second support edge 2212 are elongated along the length direction of the telescopic frame 221, so the length of the telescopic frame 221 increases. Because the included angle between the plurality of rotating edges increases, or the rotating edges rotate to a parallel position, the width of the telescopic frame 221 decreases.

[0043] The relative rotation between the plurality of rotating edges requires the action of an external force. At this time, the first elastic member 210 can exert pressure on the rotating edges in the elongation process, so that the rotating edges can rotate relative to each other. Alternatively, a torsional spring can be arranged between two adjacent rotating edges, so as to drive the rotating edges to rotate relative to each other.

[0044] When the electronic device is switched from the folded state to the unfolded state, the first screen support 110 or the second screen support 120 can drive the plurality of rotating edges to relatively rotate, so as to shorten the telescopic frame 221. At this time, when the first screen support 110 and the second screen support 120 relatively move, the first screen support 110 and / or the second screen support 120 compress one of the rotating edges, so that the rotating edge rotates, and the rotating edge drives the first support edge 2211 and / or the second support edge 2212 to move close to each other, so that the included angle between the plurality of rotating edges decreases, and thus the length of the telescopic frame 221 decreases and the width increases.

[0045] The telescopic body 220 in this scheme has a simpler structure and lower cost compared with the telescopic motor or telescopic cylinder.

[0046] In the above embodiment, when the telescopic body 220 deforms, the size in the width direction will be shortened, so that the electronic device moves in two opposite directions during the unfolding process. For example, one end of the first elastic member 210 abuts against the first screen support 110, and the other end of the first elastic member 210 abuts against one of the rotating edges. At least one of the rotating edges on the side of the telescopic body 220 away from the first elastic member 210 abuts against the second screen support 120. During the movement of the first screen support 110, the end of the first elastic member 210 abutting against the first screen support 110 always needs to abut against the first screen support 110, so the end of the first elastic member 210 abutting against the first screen support 110 moves toward the movement direction of the first screen support 110. The end of the first elastic member 210 abutting against the rotating edge moves toward the telescopic body 220 due to the telescopic body 220 being shortened in the width direction, so that the end of the first elastic member 210 abutting against the rotating edge presses against the telescopic body 220.

[0047] In another alternative embodiment, as shown in Figure 6 and Figure 7 , the plurality of rotating edges can respectively include a first rotating edge 2213, a second rotating edge 2214, a third rotating edge 2215, a fourth rotating edge 2216, a fifth rotating edge 2217, and a sixth rotating edge 2218. The first rotating edge 2213, the second rotating edge 2214, and the third rotating edge 2215 are located on one side of the first support edge 2211, and the fourth rotating edge 2216, the fifth rotating edge 2217, and the sixth rotating edge 2218 are located on the other side of the first support edge 2211. The first support edge 2211, the first rotating edge 2213, the second rotating edge 2214, the third rotating edge 2215, the second support edge 2212, the fourth rotating edge 2216, the fifth rotating edge 2217, and the sixth rotating edge 2218 can be sequentially hinged end to end.

[0048] In this scheme, the telescopic frame 221 is an octagonal structure, and the opposite sides of the first support side 2211 and the second support side 2212 each have three rotating sides, so that the telescopic frame 221 has a larger telescopic length. At the same time, the rotating angle of the rotating side is smaller.

[0049] Further, the first support side 2211 is parallel to the second support side, and the second rotating side 2214 is parallel to the fifth rotating side 2217. The length of the first support side 2211 is the same as that of the second support side 2212, the length of the second rotating side 2214 is the same as that of the fifth rotating side 2217, and the lengths of the first rotating side 2213, the third rotating side 2215, the fourth rotating side 2216, and the sixth rotating side 2218 are the same. In this scheme, the telescopic frame 221 is more regular, so the support performance for the flexible screen is better.

[0050] Of course, the telescopic frame 221 described above is not limited to an octagonal structure, but can also be a hexagonal structure, that is, the rotating side is four, and the opposite sides of the first support side 2211 each have two, of course, the number of rotating sides can also be other structures, which are not limited herein.

[0051] Optionally, in the case that the electronic device is in the folded state, the included angle between the first support side 2211 and the first rotating side 2213 and the sixth rotating side 2218 on the two sides thereof can each be 135°. The included angle between any two rotating sides connected between the first rotating side 2213, the second rotating side 2214, and the third rotating side 2215, and the fourth rotating side 2216, the fifth rotating side 2217, and the sixth rotating side 2218 can be 135°. The included angle between the second support side 2212 and the third rotating side 2215 and the fourth rotating side 2216 on the two sides thereof can each be 135°.

[0052] In the case that the electronic device is in the unfolded state, the included angle between the first support side 2211 and the first rotating side 2213 and the sixth rotating side 2218 on the two sides thereof can be 90°. The included angle between any two rotating sides connected between the first rotating side 2213, the second rotating side 2214, and the third rotating side 2215, and the fourth rotating side 2216, the fifth rotating side 2217, and the sixth rotating side 2218 can be 180°. The included angle between the second support side 2212 and the third rotating side 2215 and the fourth rotating side 2216 on the two sides thereof can each be 90°.

[0053] Of course, the angle between the support side and the rotating side, and the angle between the rotating side and the rotating side can be flexibly set, which is not limited to the angles listed herein.

[0054] In another alternative embodiment, the telescopic body 220 may further include a second elastic member 222, one end of which abuts against the first support edge 2211, and the other end of which abuts against the second support edge 2212. The second elastic member 222 may extend or shorten in the direction of approaching or moving away from the flexible screen.

[0055] In this design, the second elastic element 222 is located within the space enclosed by the supporting edge and the rotating edge. The second elastic element 222 provides deformation force to the telescopic frame 221, thus making the telescopic frame 221 more prone to deformation. Compared to using a torsion spring to rotate the rotating edge, this design is easier to assemble, easier to manufacture, and lower in cost.

[0056] like Figure 8 As shown, in another optional embodiment, at least one side of the first support edge 2211 and the second support edge 2212 is an elastic telescopic edge, which can extend or shorten along the extension direction of the opposite sides on which the rotating edge is provided. Here, the extension direction of the elastic telescopic edge can be the same as the extension direction of the first elastic member 210, or it can be understood as the width direction of the telescopic frame.

[0057] In a specific embodiment, when the electronic device switches from a retracted state to an extended state, the rotating edges on both sides of the first support edge 2211 and the second support edge 2212 rotate relative to each other. At the same time, at least one of the first support edge 2211 and the second support edge 2212 extends to accommodate the rotation of the rotating edge, thereby increasing the distance between the first support edge 2211 and the second support edge 2212. At this time, the telescopic frame 221 extends. Figure 8 The dashed frame structure shown is the telescopic frame 221 in its extended state.

[0058] When the electronic device switches from the unfolded state to the retracted state, the first screen bracket 110 or the second screen bracket 120 can drive multiple rotating edges to rotate relative to each other, while the elastic telescopic edges are compressed, thus shortening the telescopic frame 221. Figure 8 The solid-line frame structure shown is the telescopic frame 221 in its shortened state.

[0059] The extension / retraction direction of the elastic telescopic edge is parallel to the width direction of the telescopic frame 221. Therefore, in this design, the width of the telescopic frame 221 can remain unchanged during the extension / retraction process. For example, the distance between the second rotating edge 2214 and the fifth rotating edge 2217 is the width of the telescopic frame 221, and the width of the telescopic frame 221 remains unchanged in both the retracted and extended states of the electronic device. Therefore, in the design where the first support edge 2211 and / or the second support edge 2212 are elastic telescopic edges, the telescopic frame 221 can change only in the length direction during deformation, while the width direction can remain unchanged.

[0060] In the above embodiment, when the telescopic frame 221 is deformed, the size in the width direction thereof will not be shortened, and thus the end of the first elastic member 210 abutting against the first screen support 110 needs to abut against the first screen support 110 during the movement of the first screen support 110, and thus the end of the first elastic member 210 abutting against the first screen support 110 moves towards the movement direction of the first screen support 110. The end of the first elastic member 210 abutting against the rotating edge does not move, because the telescopic frame 221 will not be shortened in the width direction thereof.

[0061] In the above embodiment, the slot edge of the accommodation slot 101 can be provided with a guide inclined surface, which is used to guide the telescopic body 220 when the telescopic body 220 is retracted into the accommodation slot 101, so that the telescopic body 220 is more simple and reliable to be retracted.

[0062] In another alternative embodiment, the number of the telescopic bodies 220 is multiple, and the multiple telescopic bodies 220 are arranged at intervals along the telescoping direction of the first elastic member 210. This scheme can reduce the volume of a single telescopic body 220 by increasing the number of the telescopic bodies 220, so that the supporting performance of the support part 200 is better.

[0063] In the above embodiment, the first elastic member 210 can always press the multiple telescopic bodies 220 during the deformation of the multiple telescopic bodies 220, so as to reduce the gap between the adjacent two telescopic bodies 220, and thus the supporting effect of the support part 200 is better.

[0064] In the above embodiment, when the telescopic body 220 is located outside the accommodation slot 101, the two ends of the telescopic body 220 can be extended, and thus the telescopic body 220 extends in two opposite directions, so that the telescoping length of the telescopic body 220 is large, and thus the telescoping amount of the telescopic body 220 to be set is large, which is not conducive to the manufacture of the telescopic body 220.

[0065] Therefore, in another alternative embodiment, the support part 200 can further include an accommodation part 230, which can be provided with an accommodation slot 231, and the accommodation part 230 is movably arranged in the accommodation slot 101, the slot opening of the accommodation slot 231 faces the side where the flexible screen is located, and the multiple telescopic bodies 220 are accommodated in the accommodation slot 231. In this scheme, the telescopic body 220 is located in the accommodation slot 231 of the accommodation part 230, and thus when the telescopic body 220 is located outside the accommodation slot 101, the telescopic body 220 can only be elongated in the direction from the slot bottom to the slot opening of the accommodation slot 231, so that the telescopic body 220 is elongated on one side, and thus the telescoping amount of the telescopic body 220 is small, which is conducive to the manufacture of the telescopic body 220.

[0066] In the above embodiment, the first elastic part can extend into the accommodating groove 231, and the first elastic member 210 is pressed against the telescopic body 220 by the sidewall of the accommodating groove 231, so that the telescopic body 220 is not easy to jump when deformed when extending out of the accommodating groove 101, and collision with other components is avoided.

[0067] In another alternative embodiment, the sidewall of the accommodating part 230 can be provided with a through hole in communication with the accommodating groove 231, and one end of the first elastic member 210 passes through the through hole and is connected to the telescopic body 220. In this scheme, the sidewall of the accommodating part 230 is provided with a through hole, which facilitates the connection of the first elastic member 210 to the telescopic body 220 through the through hole, so that the structure of the supporting part 200 is simpler.
