Such display screens can not only adapt to diverse installation environments but also enhance visual expressiveness and interactivity by changing their forms. However, in practical applications, in order to achieve the best viewing angle of the LED flexible display screen in different scenarios, it is often necessary to adjust the whole or part of its angle.

[0003] Traditionally, the angle adjustment of the LED flexible display screen mainly relies on adjusting the included angle of the display screen box body. When adjusting the included angle of the display screen box body, it is necessary to loosen each fastening screw on the hinge one by one to make the hinge return to its movable state; then, according to the required layout angle, adjust the included angle between the display screen box bodies; finally, lock all the fastening screws in sequence again to ensure that the hinge is stably maintained at the set angle. It can be seen that the adjustment process of the existing angle adjustment device is not only cumbersome but also time-consuming and laborious, greatly affecting the installation efficiency of the display screen. Summary of the Utility Model

[0040] The present utility model will be further described in detail below in conjunction with the specific embodiments and the accompanying drawings.

[0041] The angle adjustment of the traditional LED flexible display mainly relies on adjusting the included angle of the display cabinet. When adjusting the included angle of the display cabinet, it is necessary to loosen each fastening screw on the hinge one by one to make the hinge return to its movable state; then, according to the required layout angle, adjust the included angle between the display cabinets; finally, lock all the fastening screws again to ensure that the hinge is stably maintained at the set angle. It can be seen that the adjustment process of the existing angle adjustment device is not only cumbersome but also time-consuming and laborious, which greatly affects the installation efficiency of the display. To solve the above problems, as Figure 1 and Figure 2 shown, the present application provides an angle adjustment device, including a first connecting bracket 1 and a second connecting bracket 2 that are hinged to each other. Among them, the first connecting bracket 1 has a first mounting surface 11, and the first mounting surface 11 is used to connect to one display cabinet of the LED flexible display. The second connecting bracket 2 has a second mounting surface 21, and the second mounting surface 21 is used to connect to another display cabinet of the LED flexible display.

[0042] The angle adjustment device further includes an angle adjustment mechanism 3, which includes a fixed seat 31 and a movable seat 32 extending along the same arc direction. Among them, the fixed seat 31 is connected to the first connection bracket 1, and the first connection bracket 1 moves following the movement of the fixed seat 31. The movable seat 32 is connected to the second connection bracket 2, and the second connection bracket 2 moves following the movement of the movable seat 32. The angle adjustment mechanism 3 further includes a driving component 33, which is used to drive the fixed seat 31 and the movable seat 32 to move relatively in the above-mentioned same arc direction. When in use, only by driving the fixed seat 31 and the movable seat 32 to move relatively in the above-mentioned same arc direction through the driving component 33, the first connection bracket 1 and the second connection bracket 2 can form a relative movement, thereby adjusting the included angle between the first mounting surface 11 and the second mounting surface 21, and thus adjusting the included angle between the two display boxes on the LED flexible display screen, so as to achieve the purpose of adjusting the bending angle of the LED flexible display screen. Compared with the traditional method of loosening each fastening screw on the hinge, the angle adjustment device of the present application is more simple and convenient to operate when adjusting the bending angle of the LED flexible display screen. When the included angle between the first mounting surface 11 and the second mounting surface 21 is equal to 180°, the LED flexible display screen is in a flat state; when the included angle between the first mounting surface 11 and the second mounting surface 21 is greater than 180°, the LED flexible display screen is in a convex arc surface; when the included angle between the first mounting surface 11 and the second mounting surface 21 is less than 180°, the LED flexible display screen is in a concave arc surface.

[0043] As Figure 1 and Figure 2 shown, in an embodiment of the present application, the driving component 33 includes a knob 331, a transmission shaft 332, a gear 333 and a rack 334. Among them, the transmission shaft 332 is rotatably inserted into the fixed seat 31, the knob 331 is connected to one end of the transmission shaft 332, and the transmission shaft 332 is driven to rotate by rotating the knob 331. The gear 333 is connected to the other end of the transmission shaft 332, and the gear 333 is driven to rotate by the transmission shaft 332. The rack 334 is installed on the movable seat 32 and extends along the arc direction of the movable seat 32. Since the gear 333 and the rack 334 are in meshing transmission, when the gear 333 rotates, it drives the rack 334 to move along the arc direction, thereby driving the movable seat 32 to move along the arc direction, driving the second connection bracket 2 to move relative to the first connection bracket 1, and thus changing the included angle between the two display boxes on the LED flexible display screen, so as to achieve the purpose of adjusting the bending angle of the LED flexible display screen.

[0044] As Figure 1 and Figure 2 shown, in an embodiment of the present application, in order to intuitively understand the rotation angle of the knob 331, the knob 331 is also marked with angle scales. By reading the angle scales, the actual rotation angle of the knob 331 can be intuitively understood, and the size of the included angle between the first mounting surface 11 and the second mounting surface 21 can also be known.

[0045] As Figure 1 and Figure 2 shown, in an embodiment of the present application, a disc portion 311 corresponding to the knob 331 is provided on the fixed seat 31. A limiting protrusion is provided on one side of the knob 331 facing the disc portion 311, and a plurality of limiting grooves 312 are sequentially provided on the disc portion 311 along the circumferential direction. When the knob 331 rotates to a specified angle, the limiting protrusion extends into the corresponding limiting groove 312, thereby limiting the knob 331 to the specified angle, that is, limiting the transmission shaft 332 and the gear 333 to the specified angle, that is, fixing the relative positions of the fixed seat 31 and the movable seat 32, thereby fixing the included angle between the first mounting surface 11 and the second mounting surface 21, that is, fixing the included angle between the two display screen boxes on the LED flexible display screen, so as to achieve the function of fixing the bending angle of the LED flexible display screen.

[0046] As Figure 1 and Figure 2 shown, in an embodiment of the present application, the angle adjustment device further includes a knob fastener 335. The knob fastener 335 is connected to the transmission shaft 332. Specifically, the knob fastener 335 can be a wing bolt. An internal threaded hole is provided at the axis of the transmission shaft 332, and the knob fastener 335 is threadedly connected to the transmission shaft 332. By screwing the knob fastener 335, the knob 331 is pressed against the disc portion 311 to form a tight connection. Conversely, the knob fastener 335 can also be loosened to enable the knob 331 to rotate relative to the disc portion 311, thereby realizing the angle adjustment function between the fixed seat 31 and the movable seat 32, that is, realizing the adjustment function of the included angle between the two display screen boxes on the LED flexible display screen, so as to realize the adjustment of the bending angle of the LED flexible display screen.

[0047] As Figure 1 and Figure 2 shown, in an embodiment of the present application, the first connection bracket 1 includes a first substrate portion 12 and a first side plate portion 13. Specifically, the first mounting surface 11 is provided on the first substrate portion 12, and the first side plate portion 13 and the first substrate portion 12 are integrally formed. The first side plate portion 13 also needs to be perpendicular to the hinge axis of the first connection bracket 1 and the second connection bracket 2, and the first side plate portion 13 extends along the arc direction. When the first side plate portion 13 moves relative to the second side plate portion 23, the first side plate portion 13 is always in this arc direction.

[0048] As Figure 1 and Figure 2As shown, in an embodiment of the present application, the second connecting bracket 2 includes a second base plate portion 22 and a second side plate portion 23. Specifically, the second mounting surface 21 is provided on the second base plate portion 22, and the second base plate portion 22 and the second side plate portion 23 are integrally formed. The second side plate portion 23 is arranged parallel to the first side plate portion 13. To enable the second side plate portion 23 and the first side plate portion 13 to move relatively on the same arc, therefore, the second side plate portion 23 extends along the same circular arc direction of the first side plate portion 13. When the angle adjustment mechanism 3 drives the first connecting bracket 1 and the second connecting bracket 2 to move relatively, the second side plate portion 23 and the first side plate portion 13 always maintain a relative movement relationship.

[0049] As Figure 1 and Figure 2 shown, in an embodiment of the present application, the angle adjustment device further includes a sliding guide member 4 and a guide groove 5. Among them, the guide groove 5 is provided on one of the first side plate portion 13 and the second side plate portion 23, the first end of the sliding guide member 4 is connected to the other of the first side plate portion 13 and the second side plate portion 23, the second end of the sliding guide member 4 extends into the guide groove 5, and is slidably connected to the guide groove 5. Since the sliding guide member 4 can only slide within the guide groove 5, therefore, the sliding guide member 4 and the guide groove 5 can restrict the movement path between the first side plate portion 13 and the second side plate portion 23, and prevent the first side plate portion 13 and the second side plate portion 23 from being misaligned and disengaged. The sliding guide member 4 can specifically be a pin or the like.

[0050] As Figure 1 and Figure 2 shown, in an embodiment of the present application, the guide groove 5 is a strip-shaped groove extending along the circular arc direction. When the first side plate portion 13 and the second side plate portion 23 move relatively, the sliding guide member 4 can always slide within the strip-shaped groove without interference.

[0051] As Figure 1 and Figure 2 shown, in an embodiment of the present application, the angle adjustment device further includes a side plate limiting member 6 and a side plate limiting groove 7. Among them, the side plate limiting groove 7 is provided on one of the first side plate portion 13 and the second side plate portion 23, and one end of the side plate limiting member 6 is connected to the other of the first side plate portion 13 and the second side plate portion 23. To achieve the positioning of the first side plate portion 13 and the second side plate portion 23 at different relative movement angles, the number of the side plate limiting grooves 7 is multiple, and each side plate limiting groove 7 is arranged in sequence along the circular arc direction. When the second side plate portion 23 moves relative to the first side plate portion 13 to a specified position, the other end of the side plate limiting member 6 extends into the corresponding side plate limiting groove 7, so as to achieve the positioning of the first side plate portion 13 and the second side plate portion 23 at different relative movement angles, and assist in the positioning of the included angle between the two display screen boxes on the LED flexible display screen.

[0052] The present application also provides an LED flexible display screen, which includes a flexible module (not shown in the figure), a box body (not shown in the figure), and the angle adjustment device in the above embodiment.

[0053] Among them, the flexible module is an image display component of the LED flexible display screen. To meet the needs of different installation scenarios, the flexible module can be bent. The box body is installed on the back side of the flexible module, and the angle adjustment device is connected between two adjacent box bodies. By adjusting the included angle between the two box bodies through the angle adjustment device, the bending radian of the flexible module can be adjusted. Since the above LED flexible display screen includes the angle adjustment device in the above embodiment, it also has the advantages of the angle adjustment device in the above embodiment.

[0054] The foregoing is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present application shall be included within the protection scope of the present application.
