The conveyor belt 430 may also move the flexible screen 300 along the first support 200 during the relative sliding of the first casing 100 and the first support 200. Specifically, when the first casing 100 slides in a direction away from the first support 200, the second segment of the flexible screen 300 moves from the first side of the first support 200 to the second side of the first support 200, so that the display area of the flexible screen 300 on the second side of the first support 200 is increased. In a case where the first housing 100 slides in a direction close to the first support 200, the second section of the flexible screen 300 moves from the second side of the first support 200 to the first side of the first support 200, thereby reducing a display area of the flexible screen 300 on the second side of the first support 200.

In the above embodiment, the conveyor belt 430 is used to move the flexible screen 300 and the first housing 100 relative to the first support 200, so as to reduce the friction between the flexible screen 300 and the first support 200. In addition, in the process that the flexible screen 300 moves relative to the first support member 200 along with the conveyor belt 430, there is no relative sliding between the flexible screen 300 and the conveyor belt 430, so that the flexible screen 300 can be prevented from being scratched in the process of moving relative to the first support member 200, and the purpose of protecting the flexible screen 300 is achieved.

Referring to fig. 19 and 20, the first support 200 may further include a second guide groove 220, and the first housing 100 may further be provided with a first guide rail 110 adapted to the second guide groove 220. The first guide rail 110 may be slidably engaged with the second guide groove 220, a limiting protrusion is disposed in the second guide groove 220, and a positioning block abutting against the limiting protrusion for limiting is disposed on the first guide rail 110, so that the first guide rail 110 is prevented from sliding out of the second guide groove 220 by the limiting protrusion abutting against the positioning block, and the first housing 100 moves excessively relative to the first support 200 to damage the flexible screen 300.

Referring to fig. 1 to 3, and 7 to 9, a side of the conveyor belt 430 near the first housing 100 may be provided with a first tooth structure. One side of the first casing 100 close to the conveyor belt 430 is provided with a second tooth structure, and the first tooth structure is engaged with the second tooth structure, so that the conveyor belt 430 can drive the first casing 100 to move relative to the first support 200, and further drive the flexible screen 300 to move relative to the first support 200 along the conveyor belt 430, thereby increasing or decreasing the display area of the flexible screen 300. Alternatively, the second tooth structure may be located on an inner wall of the first housing 100. Specifically, the second tooth structure may be located on an inner wall of the first casing 100 close to the second side of the first supporting member 200, so that the conveyor belt 430 may not only drive the first casing 100 to move relative to the first supporting member 200, but also support the first casing 100, thereby improving the stability of the movement of the first casing 100 relative to the first supporting member 200.

The transmission manner of the transmission belt 430 and the first casing 100 is many, for example, the transmission belt 430 may also be fixedly connected to an end of the first casing 100 near the second section of the flexible screen 300, or the transmission belt 430 may also drive the first casing 100 to move relative to the first support 200 through friction. Therefore, the embodiment of the present application does not limit the specific connection manner of the conveyor belt 430 and the first casing 100.

Referring to fig. 3, 15, the driving gear set 410 may include a sun gear 411, a planetary gear 412, an outer ring gear 413, and a carrier 414. The support frame 414 is a structural member, and provides a mounting base for the sun gear 411, the planet gears 412, and the outer ring gear 413. Optionally, the sun gear 411, the planet gears 412 and the outer ring gear 413 are all rotationally engaged with the carrier 414. The radius of the outer ring gear 413 may be larger than that of the central gear 411, the central gear 411 is disposed in the outer ring gear 413, the central gear 411 and the outer ring gear 413 are rotatable around the same axis, the planet gear 412 is disposed between the outer ring gear 413 and the central gear 411, the inner side wall of the outer ring gear 413 is provided with a third tooth structure, and the planet gear 412 is respectively engaged with the central gear 411 and the outer ring gear 413. Further, the electronic device may further include a driving member 900, the driving member 900 is connected to the central gear 411, and the driving member 900 drives the central gear 411 to rotate, so as to drive the planetary gear 412 and the outer ring gear 413 to rotate by using the central gear 411.

In the above embodiment, the sun gear 411 and the planet gear 412 are disposed in the outer ring gear 413, so as to reduce the volume of the driving wheel set 410, and further improve the utilization rate of the internal space of the electronic device. In addition, the planetary gear 412 is used for transmission, so that the rotating speed of the outer ring gear 413 is smaller than that of the central gear 411, the purpose of speed reduction is achieved, the driving piece 900 can be directly connected with the central gear 411, the length of a transmission shaft of the driving piece 900 is shortened, the power structural strength is improved, and the service life of a power system is prolonged. Compared with a planetary gear reduction box commonly used in the industry, the driving wheel set 410 can reduce the number of gear monomers and reduce noise caused by multi-gear matching. The drive 900 may be a motor.

Referring to fig. 1 to 3, an outer sidewall of the outer ring gear 413 has a fourth tooth structure, and an inner sidewall of the conveyor belt 430 is provided with a fifth tooth structure, with which the fourth tooth structure is engaged. The transmission precision can be ensured by the transmission of the transmission belt 430 and the outer ring gear 413 through a tooth structure, so that the size of the display surface of the electronic device can be accurately controlled. Specifically, the distance that the flexible screen 300 moves relative to the first support member 200 can be controlled by controlling the rotation angle of the driving member 900, so as to control the size of the display surface of the electronic device.

Referring to fig. 2, the electronic device may further include a power recovery motor 800, the power recovery motor 800 is disposed on the first supporting member 200, and the power recovery motor 800 is connected to the conveyor belt 430, so that the conveyor belt 430 can drive the power recovery motor 800, and further the power recovery motor 800 is utilized to convert the excess kinetic energy into electric energy for recycling, thereby improving the electric energy utilization rate.

Referring to fig. 1 and 2, the first casing 100 may be provided with a screen supporting plate on which the first section of the flexible screen 300 may be supported to prevent the first section of the flexible screen 300 from being depressed by a force. Optionally, the first section of the flexible screen 300 is fixedly attached to the first casing 100, so that the stability of the assembly of the flexible screen 300 and the first casing 100 can be improved, the first section of the flexible screen 300 can be prevented from being bent, and the first section of the flexible screen 300 is protected.

Referring to fig. 1 to 6, the electronic device may further include a second support 500, the second support 500 is disposed on a side of the second section of the flexible screen 300 close to the first support 200, and the second support 500 is movable along the first support 200 along with the second section of the flexible screen 300. In case the second support 500 is moved to the second side of the first support 200, the side of the second support 500 facing away from the flexible screen 300 is supported to the first support 200. The second supporting member 500 moves along the first supporting member 200 along with the flexible screen 300, so that the height difference between the first supporting member 200 and the first casing 100 can be compensated by the second supporting member 500, so that the second supporting member 500 can be supported on the first supporting member 200 when the first section of the flexible screen 300 moves to the second side of the first supporting member 200, and the second section of the flexible screen 300 is prevented from sinking after being stressed. Optionally, the thickness of the first support 200 is not less than the thickness of the screen support plate supporting the first segment of the flexible screen 300 on the first housing 100.

In the above embodiment, the second supporting member 500 moves along the first supporting member 200 along with the flexible screen 300, and can dynamically support the second section of the flexible screen 300, that is, the area of the second supporting member 500 on the second side of the first supporting member 200 is always equal to the area of the second section of the flexible screen 300 on the second side of the first supporting member 200, so as to ensure that the second supporting member 500 can provide effective support for the second section of the flexible screen 300, and prevent the second section of the flexible screen 300 from sinking after being stressed. Because the second supporting member 500 and the flexible screen 300 move synchronously, the size of the display area of the electronic device can be adjusted steplessly within the adjustable range of the display area of the display screen of the electronic device, and the flexible screen 300 can be effectively supported within the adjustable range of the display area of the electronic device, so that the flexible screen 300 is prevented from being depressed under stress. In addition, the second supporting member 500 is located at one side of the second section of the flexible screen 300 close to the first supporting member 200, so that mutual friction between the flexible screen 300 and the first supporting member 200 can be avoided, abrasion of the flexible screen 300 is avoided, and the service life of the flexible screen 300 is prolonged.

One end of the second supporting member 500 close to the first casing 100 may be connected to the first casing 100, so that the first casing 100 may directly pull the second supporting member 500 to move along with the conveyor belt 430, thereby reducing the stress on the flexible screen 300 and achieving the purpose of protecting the flexible screen 300. Of course, the second support member 500 may also be adhered to a side of the second section of the flexible screen 300 adjacent to the first support member 200.

Referring to fig. 10, the width and/or length of second support 500 may be no less than the width and/or length of the second section of flexible screen 300 to enable second support 500 to effectively support the second section of flexible screen 300. Referring to fig. 5 and 6, optionally, the second side of the first support 200 is provided with a supporting surface on which the second support 500 may be supported to provide a stable supporting force for the flexible screen 300. Moreover, the second side of the first supporting member 200 is provided with a supporting surface, which can reduce the requirement on the hardness of the second supporting member 500, and further provide a wider material selection space for the second supporting member 500, and the hardness of the second supporting member 500 can be reduced under the support of the supporting surface of the second side of the first supporting member 200. Optionally, the second supporting member 500 may be a supporting layer made of a flexible material, so that the second supporting member 500 can be bent after being stressed, and further the second supporting member 500 can be moved along the surface of the second supporting member 500 under the driving of the first casing 100. Further, a side of the second support member 500 facing away from the flexible screen 300 is provided with a V-shaped groove to reduce the internal stress generated after the second support member 500 is bent.

There are many types of flexible materials, such as: polyester elastomer materials, propylene-based elastomer materials, ethylene-based elastomer materials, fluorine/silicon elastomer materials, and the like. Therefore, the present application does not limit the specific material of the second supporting member 500.

Referring to fig. 4, 5 and 10, the second support 500 may include a plurality of support bodies 520, the support bodies 520 are elongated, the support bodies 520 are disposed in parallel and spaced apart on a side of the flexible screen 300 close to the first support 200, and the support bodies 520 are perpendicular to a moving direction of the flexible screen 300. The plurality of support bodies 520 are disposed in parallel and spaced at intervals on the flexible screen 300, that is, two adjacent support bodies 520 may be connected by the flexible screen 300, so that the second support 500 may be bent at a gap between the two adjacent support bodies 520, and thus the second support 500 may be bent along the surface of the first support 200. The support body 520 is perpendicular to the moving direction of the flexible screen 300, so that the support body 520 may be bent along the edge of the first support 200, enabling the second support 500 to be better supported on the first support 200. The width of the side of the support body 520 close to the flexible screen 300 may be greater than the width of the side of the support body 520 far from the flexible screen 300, so that a "V" or wedge-shaped gap is formed between two adjacent support bodies 520, and thus the area of the support body 520 supporting the flexible screen 300 may be increased while avoiding mutual pressing of the two support bodies 520. The supporting body 520 can be made of hard materials to reduce the deformation of the supporting body 520 after being stressed, so that better support is provided for the flexible screen 300, and the flexible screen 300 is prevented from being depressed after being stressed.

It should be noted that one of the purposes of the support body 520 is to support the flexible screen 300 to prevent the flexible screen 300 from sinking when a user operates on the flexible screen 300. That is, the support main body 520 may support the flexible screen 300 so that the user cannot perceive the deformation of the flexible screen 300 when the user operates on the flexible screen 300. Therefore, materials that enable the amount of deformation of the support body 520 to be imperceptible to the user under the force of the user acting on the flexible screen 300 may be suitable for the support body 520 described in the above embodiments. There are many suitable materials for making the support body 520, for example: polyvinyl chloride, polypropylene, polystyrene, and the like. Therefore, the present application does not limit the specific material of the support body 520.

The second support 500 may further include a flexible connector 510, and the flexible connector 510 is disposed on a side of the support body 520 close to the flexible screen 300, that is, the plurality of support bodies 520 may be connected by the flexible connector 510, so as to reduce the stress on the flexible screen 300. The flexible connector 510 is connected to the flexible screen 300 and/or the first housing 100 so that the support body 520 can move along the surface of the first support member 200 with the flexible screen 300. The flexible connecting member 510 is connected to the first casing 100, and under the condition that the first casing 100 is far away from the first supporting member 200, the first casing 100 can directly drive the flexible connecting member 510, so as to drive the supporting bodies 520 to move, thereby reducing the stress on the flexible screen 300 and achieving the purpose of protecting the flexible screen 300. Of course, the flexible connecting member 510 can also be connected to the second section of the flexible screen 300, and the second section of the flexible screen 300 is used to move the flexible connecting member 510 relative to the first supporting member 200. Specifically, the flexible connecting member 510 may be fixedly attached to a side of the second section of the flexible screen 300 close to the first support member 200. Of course, flexible connector 510 may also be connected to both first housing 100 and the second section of flexible screen 300.

The flexible connector 510 may be made of a flexible material. There are many types of flexible materials, such as: polyester elastomer materials, propylene-based elastomer materials, vinyl elastomer materials, fluoro/silicone elastomer materials, and the like. The present application is therefore not limited to the specific material of the flexible connector 510.

Referring to fig. 1 and 2, the supporting body 520 may be engaged with the first tooth structure, and the conveyor belt 430 may drive the second support 500 and the flexible screen 300 to switch between the first side of the first support 200 and the second side of the first support 200 when the first housing 100 moves relative to the first support 200. The supporting bodies 520 are engaged with the conveyor belt 430, that is, the first tooth structures on the conveyor belt 430 can be inserted into the gaps between two adjacent supporting bodies 520, so that the conveyor belt 430 drives the second supporting member 500 to move relative to the first supporting member 200 by acting on the supporting bodies 520. The second section of the flexible screen 300 may be adhered to the conveyor belt 430 so that the flexible screen 300 may be moved along the surface of the first support member 200 along with the second support member 500 in both directions by the conveyor belt 430.

In the above embodiment, the engagement between the supporting body 520 and the conveyor belt 430 can ensure that the acting force of the conveyor belt 430 on the second supporting member 500 can be uniformly distributed on the second supporting member 500, so as to avoid the second supporting member 500 from being damaged due to a large local force, and the conveyor belt 430 can also guide the second supporting member 500 to bend, so as to prevent the flexible screen 300 from bending excessively and protect the flexible screen 300. In addition, the engagement of the second support 500 with the conveyor belt 430 ensures that the flexible screen 300 and the second support 500 are in a tensioned state, thereby improving the display effect of the flexible screen 300.

Referring to fig. 3, as the degree of bending of the second support 500 gradually increases, the distance between the sides of the adjacent two support bodies 520 away from the flexible connector 510 decreases.
