[0031] The following will describe in detail some embodiments of the present application with reference to the drawings. Without conflict, the following embodiments and the features in the embodiments can be combined with each other.

[0032] The corner protection device of the present application belongs to the technical field of display screens. Display screens are developing more and more towards high-end. Display screen products on the market tend to be light and thin. Especially in the rental screen market, due to applications in different places, they need to be disassembled and transported continuously. During the disassembly and transportation process, the display screen is very easy to be bumped. For display screen products, the most easily damaged parts are the corners of the display module and the lamp beads near the outermost side. If the lamp beads on the display module are damaged, it will cause dead pixels on the entire screen.

[0033] As Figures 1 to 8 shown, according to the first aspect of the present application, the present application provides a display screen, including a display module 30, a box frame 20 and a protection structure 10. The protection structure 10 includes a contact member 11 and a protection piece 12. The display module 30 is installed on the box frame 20. The box frame 20 is provided with an installation hole 21. The protection piece 12 is in transmission connection with the contact member 11. The contact member 11 is movably installed in the installation hole 21 and is used to drive the protection piece 12 to rotate around the rotation axis, so that the protection piece 12 can extend or retract into the box frame 20 to protect the display module 30 and prevent the lamp beads 31 at the corners and the outer peripheral side of the display module 30 from being knocked and damaged, thereby improving the protection performance and installation stability of the display module 30.

[0034] Exemplarily, the abutting member 11 is disposed on the peripheral side of the cabinet frame 20. When two display screen units are spliced into an integral display screen, after the abutting member 11 on one display screen abuts against the frame of the other display screen, the abutting member 11 moves towards the inner side of the mounting hole 21 and drives the protective piece 12 to retract into the cabinet frame 20, thereby releasing the protection of the display module 30 and enabling the two display screen units to be spliced together. When the two display screen units are separated, the frame of the display screen releases the abutment against the abutting member 11, and the abutting member 11 extends out of the mounting hole 21 and at least part of its structure is located outside the cabinet frame 20, so as to drive the protective piece 12 to extend outside the cabinet frame 20 and be higher than or flush with the damaged part of the display module 30, so as to protect the display module 30 and prevent the lamp beads 31 at the corners and the outer peripheral side of the display module 30 from being damaged, thereby improving the protection performance and installation stability of the display module 30.

[0035] In an alternative embodiment, the display module 30 has an arc-shaped protective body 12a and a transmission part 12b connected to the end of the protective body 12a. The abutting member 11 is provided with a driving part, and the driving part is located in the mounting hole 21 and is in transmission connection with the transmission part 12b for driving the protective body 12a to protect the peripheral edge of the display module 30.

[0036] Exemplarily, the transmission between the transmission part 12b and the driving part can be in the form of rod transmission. For example, a transmission rod is connected between the abutting member 11 and the protective body 12a. When the abutting member 11 reciprocates along the mounting hole 21, the abutting member 11 drives the protective body 12a to rotate around the rotation axis through the transmission rod, so that the protective piece 12 can extend or retract into the cabinet frame 20; alternatively, the transmission between the transmission part 12b and the driving part can also be in the form of gear transmission. For example, the abutting member 11 is provided with a rack structure, and the protective body 12a is provided with a gear structure. The rack structure is in transmission connection with the gear structure, so that when the abutting member 11 reciprocates along the mounting hole 21, the abutting member 11 can drive the protective body 12a to rotate around the rotation axis through the cooperation of the rack structure and the gear structure. The present application does not limit this.

[0037] In an alternative embodiment, the display module 30 includes a lamp board and a bottom case. The lamp board is installed on the bottom case, and at least an arc-shaped part 32 is formed on the peripheral side of the bottom case. The shape of the arc-shaped part 32 is adapted to the shape of the protective body 12a. Wherein, the rotation axis is coaxially arranged with the arc-shaped part 32.

[0038] In an alternative embodiment, the central angle corresponding to the protective body 12a is not greater than 90 degrees, so that the rotation angle of the protective body 12a is not greater than 90 degrees, enabling the protective body 12a to protect the display module in all directions.

[0039] In an optional embodiment, the transmission portion 12b includes a connecting rod 121 and a connecting ball 121 connected to the driving portion, one end of the connecting rod 121 is connected to the protective body 12a, and the connecting ball 121 is connected to the other end of the connecting rod 121, so that the abutment member 11 can drive the connecting rod 121 to move through the cooperation between the driving portion and the connecting ball 121, and then drive the protective body 12a to rotate through the connecting rod 121.

[0040] In an optional embodiment, the driving portion includes a receiving groove formed on the abutment member 11, and the connecting ball 121 is received in the receiving groove, which has a simple structure and is convenient for processing and realization.

[0041] In an optional embodiment, the abutment 11 includes an abutment body 111 , which includes an abutment rod 1111 , a first connecting rod 1112 , and a second connecting rod 1113 , wherein the first connecting rod 1112 and the second connecting rod 1113 are spaced apart on the abutment rod 1111 to form a receiving groove.

[0042] In an optional embodiment, the abutment member 11 includes an elastic member 112, and both ends of the elastic member 112 abut against the abutment rod 1111 and the box frame 20 respectively, so as to reset the abutment member body 111 to drive the protective body 12a to extend out of the box frame 20, thereby providing comprehensive protection for the display module 30.

[0043] In an optional embodiment, the protection sheet 12 extends along the length direction and / or the width direction of the box frame 20 to protect the outer peripheral side of the display module 30 .

[0044] like Figures 1 to 8 As shown, according to the second aspect of the present application, the present application provides a protective structure 10 for a display screen, which includes a display module 30 and a box frame 20, wherein the protective structure 10 includes an abutment 11 and a protective sheet 12, the abutment 11 is movably installed in the box frame 20, and the protective sheet 12 is transmission-connected to the abutment 11, and is used to drive the protective sheet 12 to rotate around a rotation axis, so that the protective sheet 12 can extend or retract into the box frame 20 to protect the display module 30.
