[0002] With the improvement of user demand and the development of technology, the screens of electronic devices are getting bigger and bigger. Electronic devices equipped with flexible display screens can take into account the large screen demand and the portability of electronic devices, and thus are gradually favored by users.

[0003] In order to support the flexible display screen, the electronic device involved in the related art adopts two comb-tooth structures that can move relatively. However, the two comb-tooth structures that cooperate with each other have serious friction when the flexible display screen is unfolded or retracted, which will cause abnormal noise, which will undoubtedly affect the user's use. Summary of the invention

[0004] The purpose of the embodiments of the present application is to provide an electronic device that can solve the problem of abnormal noise in electronic devices involved in related technologies.

[0005] The embodiment of the present application provides an electronic device, including a first body, a second body, a movable support, a lifting support, and a flexible display screen.

[0006] The first body and the second body are movably connected, one end of the flexible display screen is connected to the first body, and the other end of the flexible display screen is connected to the second body;

[0007] The lifting support member is rotatably disposed on the first body, and the movable support member is movably disposed on the second body;

[0008] When the electronic device is in the unfolded state, the movable support member moves to the first position, the swing end of the lifting support member rises to a first height, and both the movable support member and the lifting support member abut against the flexible display screen; when the electronic device is in the folded state, the movable support member moves to the second position, the swing end of the lifting support member drops to a second height, the movable support member covers the lifting support member, and the movable support member abuts against the flexible display screen.

[0009] In the embodiment of the present application, the movable support member can move relative to the first body, the lifting support member can rotate relative to the first body, and the moving direction of the movable support member intersects with the direction of the rotation axis of the lifting support member. The lifting support member can support the flexible display screen together with the movable support member by lifting itself, or it can avoid the movable support member so that the movable support member can retract and cover at least a part of the lifting support member. It can be seen that the embodiment of the present application can support the flexible display screen together by the movable support member and the lifting support member when the electronic device is unfolded, thereby providing a better support effect. At the same time, the movement of the movable support member and the rotation of the lifting support member do not interfere with each other, so as to alleviate the friction between the two, thereby solving the problem of abnormal noise in the electronic device in the related art.

[0042] The following will be combined with the drawings in the embodiments of the present application to clearly describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments in the present application belong to the scope of protection of this application.

[0043] The terms "first", "second", etc. 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 interchangeable under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described here, and the objects distinguished by "first", "second", etc. are generally of one type, and the number of objects is not limited. For example, the first object can be one or more. In addition, "and / or" in the specification and claims represents at least one of the connected objects, and the character " / " generally indicates that the objects associated with each other are in an "or" relationship.

[0044] The electronic device disclosed in the embodiment of the present application is described in detail below through specific embodiments and application scenarios in conjunction with the accompanying drawings.

[0045] Please refer to Figure 1-Figure 26 The present application discloses an electronic device, which includes a first body 100, a second body 800, a movable support 200, a lifting support 300 and a flexible display screen 900.

[0046] The first body 100 and the second body 800 are both basic components of the electronic device, and are used to provide an installation basis for other components of the electronic device. The first body 100 and the second body 800 are movably connected, that is, the second body 800 can move relative to the first body 100, so that at least part of the first body 100 and at least part of the second body 800 can be close to or away from each other, thereby switching the electronic device between a folded state and an unfolded state.

[0047] The flexible display screen 900 is a display component of the electronic device, one end of which is connected to the first body 100, and the other end is connected to the second body 800. Since the flexible display screen 900 is easier to deform, when the electronic device switches between a folded state and an unfolded state, the display area of ​​the flexible display screen 900 can gradually decrease or increase to meet the different usage needs of users.

[0048] The movable support member 200 and the lifting support member 300 are both used to support the flexible display screen 900, that is, the movable support member 200 and the lifting support member 300 are support carriers of the flexible display screen 900. Specifically, when the electronic device is in a folded state, the movable support member 200 is used to support the flexible display screen 900. When the electronic device is in an unfolded state, all of the lifting support members 300 and the movable support member 200 jointly support the flexible display screen 900 to ensure that the flexible display screen 900 can work normally.

[0049] Specifically, the lifting support member 300 is rotatably arranged on the first body 100, and the rotation axis of the lifting support member 300 can be parallel to the direction of the winding axis of the flexible display screen 900. The mobile support member 200 is movably arranged on the second body 800. When the electronic device is in the unfolded state, the mobile support member 200 moves to the first position so that the swing end 310 of the lifting support member 300 rises to the first height, that is, the swing end 310 swings to increase the height of the lifting support member 300 in the direction in which the lifting support member 200 and the lifting support member 300 are arranged, so that the lifting support member 200 and the lifting support member 300 are both in contact with the flexible display screen 900 to achieve common support of the flexible display screen 900. Optionally, in the moving direction of the mobile support member 200, there is a distance between the mobile support member 200 and the first body 100, and the first position can be the position of the mobile support member 200 when the distance is at the maximum value.

[0050] When the electronic device is in the folded state, the mobile support member 200 moves to the second position so that the swing end 310 of the lifting support member 300 drops to the second height, that is, the swing end 310 drops to the second height so that the height of the lifting support member 300 in the direction in which the mobile support member 200 and the lifting support member 300 are arranged can be reduced, thereby making the mobile support member 200 cover at least part of the lifting support member 300, so that the mobile support member 200 supports the flexible display screen 900. Optionally, the first height is greater than the second height.

[0051] In the embodiment of the present application, the mobile support member 200 can move relative to the first body 100, and the lifting support member 300 can rotate relative to the first body 100, and the moving direction of the mobile support member 200 intersects with the direction of the rotation axis of the lifting support member 300. The lifting support member 300 can support the flexible display screen 900 together with the mobile support member 200 through its own lifting, or can avoid the mobile support member 200 so that the mobile support member 200 can retract and cover at least a part of the lifting support member 300. It can be seen that the embodiment of the present application can support the flexible display screen 900 together through the mobile support member 200 and the lifting support member 300 when the electronic device is unfolded, thereby providing a better support effect. At the same time, the movement of the mobile support member 200 and the rotation of the lifting support member 300 do not interfere with each other, so as to alleviate the friction between the two, thereby solving the problem of abnormal noise in the electronic device in the related art.

[0052] Since the lifting support member 300 is rotatably disposed on the first body 100, the height of the portion of the lifting support member 300 connected to the first body 100 cannot change. In the process of switching the electronic device from the unfolded state to the folded state, in order to prevent the mobile support member 200 from interfering with the lifting support member 300, a certain distance needs to be reserved between the mobile support member 200 and the lifting support member 300, which results in the size of the electronic device in the folded state being larger. To this end, the mobile support member 200 is optionally provided with an avoidance notch 210. When the electronic device is in the folded state, a portion of the lifting support member 300 is located in the avoidance notch 210, so that the lifting support member 300 does not affect the movement of the mobile support member 200 relative to the first body 100, thereby reducing the size of the electronic device in the folded state.

[0053] Optionally, the two ends of the lifting support member 300 in the first direction are a swing end 310 and an elastic end, that is, the elastic end is elastically connected to the first body 100. Optionally, the first direction is the moving direction of the mobile support member 200 when the electronic device switches from the folded state to the unfolded state. When the mobile support member 200 moves to the first position, because the connection between the lifting support member 300 and the first body 100 is an elastic structure, this setting method can make the lifting support member 300 avoid the mobile support member 200, thereby preventing the two from interfering. However, since the elastic end is more likely to deform elastically, the effect of the lifting support member 300 supporting the flexible display screen 900 may be deteriorated.

[0054] In order to improve the supporting effect of the lifting support member 300 on the flexible display screen 900, in another embodiment, the two ends of the lifting support member 300 in the first direction are respectively a swing end 310 and a connection end 320, and the connection end 320 is rotatably connected to the first body 100. Optionally, the connection end 320 can be a connection shaft, and the first body 100 is provided with a connection hole 130, and the connection shaft is rotatably arranged in the connection hole 130. Since the connection end 320 is a rigid structure, the connection end 320 is not easy to deform, so that the lifting support member 300 can support the flexible display screen 900 more stably. In addition, when the electronic device is in a folded state, the connection end 320 can abut against the flexible display screen 900, thereby assisting in supporting the flexible display screen 900. The avoidance gap 210 is arranged at one end of the mobile support member 200 close to the connection end 320, so that the connection end 320 does not affect the movement of the mobile support member 200 relative to the first body 100.

[0055] In one embodiment, the swing end 310 can be driven to rise to a first height or fall to a second height by a lifting device such as a linear motor, that is, the lifting device is connected to the swing end 310, and the lifting device drives the swing end 310 to rise and fall to drive the lifting support member 300 to rotate relative to the first body 100, thereby achieving the lifting support member 300 abutting against the flexible display screen 900 or making at least a portion of the lifting support member 300 away from the flexible display screen 900.

[0056] In another embodiment, the electronic device further comprises a first transmission mechanism 400, which is disposed on the first body 100 and connected to the swing end 310. The first transmission mechanism 400 is used to transmit power to the swing end 310 to drive the swing end 310 to swing, and drive the lifting support member 300 to rotate relative to the first body 100 through the swing end 310, so as to achieve the lifting support member 300 abutting against the flexible display screen 900 or to make at least part of the lifting support member 300 away from the flexible display screen 900. This embodiment directly applies the driving force to the swing end 310, so that it is easier to drive the lifting support member 300 to rotate.

[0057] In one embodiment, the first transmission mechanism 400 may be a liftable component that is transmission-connected to a lifting device such as a linear motor. In another embodiment, the first transmission mechanism 400 includes a transmission member 410, which is movably disposed on the first body 100, that is, the transmission member 410 can move relative to the first body 100. One of the transmission member 410 and the lifting support member 300 is provided with a transmission protrusion 330, and the other is provided with a transmission groove 411. The transmission protrusion 330 or the transmission groove 411 may be located at the swing end 310 of the lifting support member 300, that is, the movement of the transmission protrusion 330 or the transmission groove 411 can drive the swing end 310 to move, and the swing end 310 drives the lifting support member 300 to rotate relative to the first body 100. Optionally, the transmission member 410 may be a bar-shaped member, and the moving direction of the transmission member 410 is parallel to the rotation axis of the lifting support member 300.

[0058] Specifically, the transmission protrusion 330 is slidably matched with the transmission groove 411, that is, the transmission protrusion 330 can slide in the transmission groove 411, and the transmission groove 411 includes a first groove section 4111 and a second groove section 4112 that are connected. The height of the first groove section 4111 is greater than the height of the second groove section 4112, that is, when the transmission protrusion 330 slides from the second groove section 4112 to the first groove section 4111, the swing end 310 can rise to the first height, and when the transmission protrusion 330 slides from the first groove section 4111 to the second groove section 4112, the swing end 310 can drop to the second height. In this embodiment, the transmission is realized by matching the transmission protrusion 330 with the parts of the transmission groove 411 with different heights. The structure of this transmission method is relatively simple, and the space occupied by the transmission member 410 is relatively small.

[0059] Optionally, the shapes of the first groove section 4111 and the second groove section 4112 can both be inclined, and the inclinations of the two are different. In this case, when the transmission protrusion 330 slides in the first groove section 4111 and the second groove section 4112, the first groove section 4111 and the second groove section 4112 have low limiting capabilities for the transmission protrusion 330 in the height direction of the first groove section 4111 and the second groove section 4112, and thus there is a problem of poor rotational stability of the lifting support 300.

[0060] To avoid the above problems, in another embodiment, the first groove section 4111 can be a straight groove section, and the second groove section 4112 can be an inclined groove section. The extension direction of the first groove section 4111 is parallel to the moving direction of the transmission member 410. When the transmission protrusion 330 slides from the second groove section 4112 to the first groove section 4111, the first groove section 4111 has a higher limiting ability for the transmission protrusion 330 in the height direction of the first groove section 4111 and the second groove section 4112, thereby making the lifting support member 300 more stable in rotation relative to the first body 100. At the same time, the lifting support member 300 can be more stably maintained in the position abutting against the flexible display screen 900 to improve the supporting effect.

[0061] Optionally, the number of the lifting support member 300 may be one. When the size of the lifting support member 300 is small, the supporting effect thereof is poor; when the size of the lifting support member 300 is large, it is easy to affect the arrangement of other structures.

[0062] To avoid the above-mentioned influence, in another embodiment, the number of lifting support members 300 is at least two, and each lifting support member 300 is arranged at intervals along the moving direction of the transmission member 410. In this case, the supporting effect of the lifting support member 300 can be improved, and other structures can be avoided at the same time to facilitate the arrangement of other structures. Optionally, each lifting support member 300 is provided with at least one transmission protrusion 330, and the transmission member 410 is provided with at least one transmission groove 411. Each transmission protrusion 330 corresponds to each transmission groove 411 one by one, and slides in cooperation, thereby improving the rotation stability of the lifting support member 300.

[0063] Optionally, to prevent the transmission member 410 from falling off the first body 100 when it moves on the first body 100, one of the transmission member 410 and the first body 100 is provided with a sliding buckle 414, and the other is provided with a first slide groove 110, the sliding buckle 414 is slidably matched with the first slide groove 110, and the first slide groove 110 can not only limit the sliding direction of the sliding buckle 414, but also make the sliding buckle 414 firmly stuck in the first slide groove 110. Optionally, the number of the sliding buckles 414 is at least two, the number of the first slide grooves 110 is at least two, and each sliding buckle 414 corresponds to each first slide groove 110 one by one and slidably matches.

[0064] Optionally, in order to make the transmission member 410 move more stably on the first body 100, one of the transmission member 410 and the first body 100 is provided with a sliding guide post 415, and the other is provided with a second slide groove 120, the sliding guide post 415 and the second slide groove 120 are slidably matched, and the second slide groove 120 plays a role of sliding guide for the sliding guide post 415, so that the second slide groove 120 can make the sliding guide post 415 move more stably, thereby making the transmission member 410 move more stably. Optionally, the number of the sliding guide posts 415 is at least two, the number of the second slide grooves 120 is at least two, and each sliding guide post 415 corresponds to each second slide groove 120 one by one and slidably matches.

[0065] Optionally, the transmission member 410 may be driven to move relative to the first body 100 by an additional driving device. However, due to the limited space of the electronic device, the additional driving device occupies more space, which may affect the arrangement of other components.

[0066] In another embodiment, one of the transmission member 410 and the movable support member 200 is provided with a linkage protrusion 412, and the other is provided with a linkage groove 220, and the linkage groove 220 is a bent groove. When the linkage protrusion 412 and the linkage groove 220 are slidably matched, the movable support member 200 moves relative to the first body 100, thereby driving the transmission member 410 to move relative to the first body 100, and then driving the lifting support member 300 to rotate relative to the first body 100. Optionally, the moving direction of the movable support member 200 can be perpendicular to the moving direction of the transmission member 410. It can be seen that when the movable support member 200 moves to the first position, the lifting support member 300 can be rotated relative to the first body 100 by using the transmission member 410 and the existing linkage protrusion 412 on the movable support member 200 and slidingly cooperating with the linkage groove 220. Therefore, this setting method can realize the linkage between the movable support member 200 and the lifting support member 300. At the same time, there is no need to set up an additional driving device, which has little impact on the installation space of the electronic equipment. In addition, this setting method is less difficult to operate and is easy to control.

[0067] Optionally, the linkage protrusion 412 or the linkage groove 220 provided on the movable support member 200 can be located at a position of the movable support member 200 close to the connection end 320, so that when the movable support member 200 moves relative to the first main body 100, when the linkage protrusion 412 and the linkage groove 220 are slidably engaged, the lifting support member 300 can be free from obstruction by the movable support member 200, and the lifting support member 300 can rotate more smoothly relative to the first main body 100.

[0068] Optionally, the linkage groove 220 includes a third groove section 221 and an inclined groove section 222 which are connected in sequence, and the third groove section 221 extends along the moving direction of the movable support member 200. When the electronic device is in the unfolded state, the movable support member 200 moves to make the linkage protrusion 412 slide from the third groove section 221 to the inclined groove section 222, thereby making the transmission member 410 move relative to the first body 100 until the linkage protrusion 412 slides to the end of the inclined groove section 222 away from the third groove section 221. In this case, there may be a phenomenon that the position of the linkage protrusion 412 in the inclined groove section 222 is unstable, that is, the linkage protrusion 412 is easy to move in the inclined groove section 222.

[0069] To avoid the above phenomenon, in another embodiment, the linkage groove 220 also includes a fourth groove section 223, the third groove section 221, the inclined groove section 222 and the fourth groove section 223 are connected in sequence, the third groove section 221 and the fourth groove section 223 both extend along the moving direction of the movable support member 200, and the movable support member 200 has a first edge 230 extending along its own moving direction, and the distance between the third groove section 221 and the first edge 230 is smaller than the distance between the fourth groove section 223 and the first edge 230. The movable support member 200 moves so that the linkage protrusion 412 slides from the third groove section 221 to the inclined groove section 222 and the fourth groove section 223 in sequence. Since the extension direction of the fourth groove section 223 is the moving direction of the movable support member 200, the fourth groove section 223 can limit the linkage protrusion 412 in the moving direction of the transmission member 410, so that the linkage protrusion 412 can reliably cooperate with the fourth groove section 223, thereby making the lifting support member 300 more stably maintained in the position abutting against the flexible display screen 900, so as to further ensure the supporting effect.

[0070] Since the linkage protrusion 412 cooperates with the linkage groove 220 only after the mobile support 200 moves a certain distance, in order to achieve this purpose, the linkage protrusion 412 can be set to an elastic structure, and the linkage protrusion 412 enters the linkage groove 220 through the deformation of the linkage protrusion 412. In another embodiment, optionally, the linkage groove 220 is provided with a notch 224, and the linkage protrusion 412 can slide and cooperate with the linkage groove 220 via the notch 224. The notch 224 can be provided on the third groove section 221, that is, when the electronic device is in the unfolded state, the linkage protrusion 412 enters the third groove section 221 via the notch 224 and slides and cooperates with the third groove section 221, and when the electronic device is in the folded state, the linkage protrusion 412 and the notch 224 are arranged at intervals in the moving direction of the mobile support 200, and when the mobile support 200 moves a certain distance, the linkage protrusion 412 can enter the notch 224 and further enter the third groove section 221. In this embodiment, the linkage protrusion 412 does not need to be set as an elastic structure, so the linkage protrusion 412 will not be deformed, so that when the electronic device is in the unfolded state, the linkage protrusion 412 and the notch 224 can slide and cooperate more stably.

[0071] Optionally, the electronic device also includes a driving mechanism 500, which is disposed on the first body 100. The driving mechanism 500 is connected to the movable support member 200 so that the driving mechanism 500 can drive the movable support member 200 to move relative to the first body 100. When the linkage protrusion 412 and the linkage groove 220 are slidably engaged, the movement of the movable support member 200 can drive the transmission member 410, so that the movement of the transmission member 410 drives the lifting support member 300 to rotate relative to the first body 100.

[0072] In order to make the transmission member 410 drive the lifting support member 300 to rotate more stably relative to the first body 100, in another embodiment, the electronic device further includes a second transmission mechanism 600, and the driving mechanism 500 is connected to the mobile support member 200 through the second transmission mechanism 600, that is, the driving mechanism 500 drives the mobile support member 200 to move through the second transmission mechanism 600, and when the linkage protrusion 412 and the linkage groove 220 are slidably matched, the mobile support member 200 drives the transmission member 410 to move, so that the transmission member 410 is simultaneously connected to the second transmission mechanism 600. It can be seen that the mobile support member 200 first drives the transmission member 410 to move to the second transmission mechanism 600, and then the driving mechanism 500 can simultaneously drive the mobile support member 200 and the transmission member 410 to move through the second transmission mechanism 600. This method can shorten the transmission chain, thereby improving the transmission efficiency.

[0073] In addition, after the transmission member 410 is connected to the second transmission mechanism 600, the mobile support member 200 and the second transmission mechanism 600 can jointly drive the transmission member 410 to move, and then the transmission member 410 can more stably drive the lifting support member 300 to rotate relative to the first body 100. Alternatively, after the transmission member 410 is connected to the second transmission mechanism 600, the linkage protrusion 412 can be separated from the linkage groove 220 via the opening of the end of the linkage groove 220 away from the notch 224, so that the linkage protrusion 412 does not restrict the movement of the mobile support member 200, and only the second transmission mechanism 600 can drive the transmission member 410 to move.

Through this arrangement, the driving force output by the driving source 510 can be transmitted to the bevel gear 530 through the reduction box 520, and then transmitted to the second transmission mechanism 600 through the bevel gear 530.

[0080] Optionally, the transmission member 410 may have only one transmission protrusion 330 ; or, the transmission member 410 may have only one transmission groove 411 , but the sliding fit between one transmission protrusion 330 and one transmission groove 411 makes the rotation stability of the lifting support member 300 poor.
