[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This disclosure claims priority to Chinese patent application number 202323368309.X filed with the Chinese Patent Office on December 7, 2023, entitled “A Display Bracket Panel Rotation Structure,” the entire contents of which are incorporated by reference into this disclosure. Technical Field

[0003] The present disclosure belongs to the technical field of display brackets, and particularly relates to a display bracket panel rotation structure. Background Art

[0004] A monitor stand is a support member configured to support a monitor, typically comprising a panel fixedly connected to the center of the back of the monitor, a quick-release plate (also called a plug-in block) rotatably connected to the panel, and a socket matching the quick-release plate. The socket is connected to the end of the support arm, thereby achieving rotational support for the monitor.

[0005] The panel and quick-release plate of existing monitor stands are mostly connected by rotation through rivets, screws, etc., forming friction between the two, so that the panel can rotate 360° relative to the quick-release plate and stop at any position. However, the friction provided by this method is fixed. When the center of gravity of the monitor is at the center of the panel, this method is not wrong. However, when the center of gravity of the monitor deviates from the center of the panel and the monitor is heavy, the monitor may not be able to stop in certain positions, resulting in a poor user experience.

[0028] The preferred embodiments of the present disclosure are described in detail below with reference to the accompanying drawings so that the advantages and features of the present disclosure can be more easily understood by those skilled in the art.

[0029] The display bracket panel rotation structure includes: a quick-release plate 10, a panel 20, and a resistance-increasing unit 30, wherein the panel 20 is rotatably connected to the quick-release plate 10, and the panel 20 is configured to install a display (not shown in the figure); the resistance-increasing unit 30 is configured to form additional friction between the quick-release plate 10 and the panel 20. Optionally, the resistance-increasing unit 30 includes a brake disc 31 and a brake pad 32 matching the brake disc 31. The brake disc 31 is arranged between the quick-release plate 10 and the panel 20, and the axis of the brake disc 31 coincides with the rotation axis of the panel 20. The brake disc 31 is connected to the panel 20, and the brake pad 32 is movably connected to the quick-release plate 10. The moving direction of the brake pad 32 is the radial direction of the brake disc 31. The brake pad 32 is located outside the brake disc 31 and is pressed against the edge of the brake disc 31.

[0030] The advantage of this setting is that the brake pad can be used to apply a clamping force on the brake disc, thereby forming additional friction. Since the clamping force extends in the radial direction of the brake disc, when it is transmitted to the panel, it will not form torque on the panel, will not change the pitch angle of the panel, and will not affect the user experience; when the brake pad moves radially, the size of the clamping force can also be adjusted, thereby changing the size of the additional friction, so that the panel can drive monitors of different weights to rotate, expanding the scope of application.

[0031] In this embodiment, the brake disc 31 is provided with a plurality of positioning holes 311 evenly distributed around the axis of the brake disc 31, and the surface of the panel 20 facing the quick release plate 10 is provided with positioning protrusions 21 corresponding one-to-one to the positioning holes 311. The positioning protrusions 21 are inserted into the positioning holes 311, so that the panel 20 is connected to the brake disc 31 and rotates synchronously.

[0032] Optionally, the middle part of the brake disc 31 protrudes toward the direction where the panel 20 is located, and a circular positioning groove 312 is formed on the surface of the brake disc 31 facing the quick release plate 10. A flat gasket 313 is provided in the circular positioning groove 312. The thickness of the flat gasket 313 is equal to the groove depth of the circular positioning groove 313. The positioning hole 311 is opened on the bottom wall of the circular positioning groove 312. A center hole 314 is provided at the center of the bottom wall of the circular positioning groove 312. The center hole 314 is configured to penetrate a center rivet 40 connecting the panel 20 and the quick release plate 10. By riveting the panel 20 and the quick release plate 10 with the center rivet 40, the panel 20 and the quick release plate 10 can be rotated.

[0033] In order to enhance the stability of the brake pad 32 against the brake disc 31, in this embodiment, a U-shaped groove 321 is provided on the side of the brake pad 32 facing the brake disc 31. The U-shaped groove 321 is clamped on the edge of the brake disc 31, and the side walls and bottom walls of the U-shaped groove 321 are pressed against the edge of the brake disc 31.

[0034] In order to minimize the axial thickness of the display bracket panel rotating structure as much as possible, optionally, the surface of the quick release plate 10 facing the panel 20 is provided with a receiving groove 11 configured to accommodate the brake disc 31, and the surface of the panel 20 facing the quick release plate 10 is provided with an annular groove 22 configured to insert the groove edge of the receiving groove 11. This arrangement can completely wrap the brake disc 31 inside the display bracket panel rotating structure, avoid damage, and extend its service life.

[0035] Optionally, the groove wall 12 of the accommodating groove 11 is provided with a blind groove 13 extending along the radial direction of the brake disc 31, and the brake pad 32 is movably arranged in the blind groove 13. The bottom wall of the blind groove 13 is provided with a threaded hole 14 penetrating the groove wall 12 of the accommodating groove 11, and the threaded hole 14 extends along the radial direction of the brake disc 31. The resistance increasing unit 30 also includes a set screw 33 threadedly connected to the threaded hole 14, and the set screw 33 presses the side of the brake pad 31 away from the brake disc 32, so that the brake pad 32 presses against the brake disc 31.

[0036] In order to shield the rivet heads on the surface of the panel 20 away from the quick-release plate 10, optionally, the display bracket panel rotation structure also includes a decorative cover 50, which is connected to the surface of the panel 20 away from the quick-release plate 10. For easy connection, the bottom wall of the annular groove 22 is provided with a plurality of connection holes 221 evenly distributed around the rotation axis of the panel 20. The connection holes 221 are configured to connect the decorative cover 50 to the surface of the panel 20 away from the quick-release plate 10. Optionally, the surface of the decorative cover 50 facing the panel 20 is provided with inverted columns 51 corresponding to the connection holes 221 one by one. The inverted columns 51 pass through the connection holes 221 and hook the edge of the connection holes 221, so that the decorative cover 50 is connected to the surface of the panel 20 away from the quick-release plate 10.

[0037] In order to enable the quick release plate 10 to be precisely plugged into the socket, the display bracket panel rotation structure optionally further includes a spring washer 60 , which is arranged on the surface of the quick release plate 10 away from the panel 20 and sleeved on the end of the central rivet 40 .
