Moreover, the specific features, structures, materials or characteristics described may be combined in any one or more embodiments or examples in a suitable manner.

[0037] In the related art, the rotating chassis assembly of the mounting bracket usually has a rotating function to achieve the angle adjustment of the display. In order to facilitate the user's installation and reduce the number of parts into which the mounting bracket is disassembled before transportation, the rotating chassis assembly is usually transported as a whole. After being transported to the destination, the user passes through the rotating chassis assembly through the connecting piece and connects it to the mounting piece, so that the rotating chassis assembly and the mounting piece are connected together to complete the assembly of the mounting bracket. However, since the rotating chassis assembly, as a whole, retains its relative rotational freedom, the shaking and vibration generated during transportation will cause the rotating chassis assembly to rotate relatively, resulting in the installation position of the rotating chassis assembly cannot be leaked, and the user needs to find the installation position of the rotating chassis assembly by himself for installation, which is more complicated and the user experience is poor.

[0038] See also Figure 1 and Figure 2 , Figure 1 It is a three-dimensional structural schematic diagram of a rotating chassis assembly 100 installed with a connecting member 200 in an embodiment of the present invention; Figure 2 yes Figure 1The structural schematic diagram of the connecting member 200 and the rotating chassis assembly 100 in the disassembled state. An embodiment of the present invention provides a mounting bracket, the mounting bracket includes a connecting member 200, a mounting member (not shown) and a rotating chassis assembly 100 of an embodiment of the present invention, the connecting member 200 is arranged on the mounting portion 22 and is connected to the mounting member, and the mounting member is used to install the display. Specifically, the rotating chassis assembly 100 can be arranged on a horizontal support surface such as a desktop, or on a vertical support surface such as a wall. The mounting member can be selected as a column that can realize functions such as height adjustment, pitch angle adjustment, and horizontal orientation adjustment. The present invention does not specifically limit the shape of the mounting member. By adding the rotating chassis assembly 100 provided by the embodiment of the present invention to the mounting bracket, after completing the transportation, the user can complete the rapid assembly of the mounting member and the rotating chassis assembly 100 through the connecting member 200, the assembly is relatively simple, and the user experience is improved.

[0039] See also Figures 2 to 4 , Figure 3 yes Figure 1 A schematic structural diagram of the connecting member 200 and the rotating chassis assembly 100 in an exploded state from another perspective; Figure 4 yes Figure 2 The enlarged structural diagram of the I region. The embodiment of the present invention provides a rotating chassis assembly 100, which includes a rotating plate 10 and a bottom plate 20. The rotating plate 10 is provided with a first limiting portion 11 and a hollow portion 12, and is used to be set on a support surface. The bottom plate 20 is rotatably connected to the rotating plate 10, and is provided with a second limiting portion 21 and a mounting portion 22. When the bottom plate 20 rotates to the first position relative to the rotating plate 10, the second limiting portion 21 cooperates with the first limiting portion 11, and the relative rotational freedom of the rotating plate 10 and the bottom plate 20 is limited. The hollow portion 12 is opposite to the mounting portion 22, so that the connecting member 200 can extend from the hollow portion 12 into the mounting portion 22, and the connecting member 200 is used to connect the mounting member for mounting the display. When the bottom plate 20 rotates from the first position to the second position relative to the rotating plate 10, the second limiting portion 21 is released from the first limiting portion 11, and the bottom plate 20 and the rotating plate 10 restore the relative rotational freedom.

[0040] Specifically, the rotating plate 10 can be placed on a horizontal support surface such as a desktop, or can be set on a vertical support surface such as a wall. The first limiter 11 is set on the side of the rotating plate 10 facing the bottom plate 20, and the second limiter 21 is set on the side of the bottom plate 20 facing the chassis.

[0041] Specifically, the first limiting portion 11 and the hollow portion 12 are spaced apart from the axis around which the bottom plate 20 rotates relative to the rotating plate 10, so that during the rotation of the bottom plate 20 relative to the rotating plate 10, the positions of the first limiting portion 11 and the hollow portion 12 relative to the bottom plate 20 can change. Similarly, the second limiting portion 21 and the mounting portion 22 are spaced apart from the axis around which the bottom plate 20 rotates relative to the rotating plate 10, so that during the rotation of the bottom plate 20 relative to the rotating plate 10, the positions of the second limiting portion 21 and the mounting portion 22 relative to the rotating plate 10 can change. In this way, during the relative rotation of the bottom plate 20 and the rotating plate 10, the first limiting portion 11 and the second limiting portion 21 can be matched or unmatched. The matching of the first limiting portion 11 and the second limiting portion 21 can be selected in various forms such as snap-fit, concave-convex matching, etc.

[0042] It can be understood that the first limit portion 11 and the second limit portion 21 cooperate to limit the freedom of relative rotation of the rotating plate 10 and the bottom plate 20. The rotating plate 10 and the bottom plate 20 can only rotate relative to each other by a certain angle, for example, only by 5°, or the rotating plate 10 and the bottom plate 20 cannot rotate relative to each other at all.

[0043] By providing a first limiting portion 11 on the rotating plate 10 and a second limiting portion 21 on the bottom plate 20, the bottom plate 20 can be rotated to the first position relative to the rotating plate 10 before transportation, so that the second limiting portion 21 cooperates with the first limiting portion 11 to limit the freedom of relative rotation of the rotating plate 10 and the bottom plate 20. Even if vibration occurs during transportation, the hollow portion 12 and the mounting portion 22 can remain relative to each other. The user can extend the connecting member 200 from the hollow portion 12 into the mounting portion 22 and connect it with the mounting member. The assembly of the mounting bracket is relatively simple, which improves the user experience. Moreover, after the assembly is completed, the user can use external force to rotate the bottom plate 20 relative to the rotating plate 10 from the first position to the second position, so that the second limiting portion 21 and the first limiting portion 11 are released from cooperation, and the bottom plate 20 and the rotating plate 10 restore the freedom of relative rotation, so as to adjust the angle of the display.

[0044] In one embodiment of this implementation, please refer to Figures 4 to 6 , Figure 5 yes Figure 3 Schematic diagram of the enlarged structure of region II; Figure 6 yes Figure 1The figure is a cross-sectional view of the connecting member 200 and the rotating chassis assembly 100 on the section passing through the locking member 30. One of the first limiting portion 11 and the second limiting portion 21 is configured as a groove body 111, and the other of the first limiting portion 11 and the second limiting portion 21 is configured as a protrusion 211. When the bottom plate 20 is in the first position relative to the rotating plate 10, the protrusion is located inside the groove body 111. When the bottom plate 20 is in the second position relative to the rotating plate 10, the protrusion is located outside the groove body 111. In this embodiment, the first limiting portion 11 is configured as the groove body 111, and the second limiting portion 21 is configured as the protrusion 211. In other embodiments, the first limiting portion 11 can also be configured as the protrusion 211, and the second limiting portion 21 can also be configured as the groove body 111. The mating and dismating of the protrusion 211 and the groove body 111 are relatively easy, and the structure is relatively simple.

[0045] In this embodiment, when the bottom plate 20 is at the second position relative to the rotating plate 10 , the bottom plate 20 and the rotating plate 10 have a rotatable freedom of 173°.

[0046] In one embodiment of this implementation, please refer to Figures 4 to 6 The groove body 111 has a first inner side wall 1111 and a second inner side wall 1112 which are opposite to each other in the circumferential direction, and the projection has a first side surface 2111 and a second side surface 2112 which are opposite to each other. When the projection is located in the groove body 111, the first inner side wall 1111 abuts against the first side surface 2111, and the second inner side wall 1112 abuts against the second side surface 2112. With such a configuration, the projection can be stuck in the groove body 111, and the bottom plate 20 and the rotating plate 10 cannot rotate relative to each other.

[0047] In one embodiment of this implementation, please refer to Figures 4 to 6 , the first inner side wall 1111 is an inwardly concave arc surface, and the first side surface 2111 is an outwardly convex arc surface. Specifically, the first inner side wall 1111 and the first side surface 2111 fit together to improve the buffering capacity against vibration and reduce the risk of the first limit portion 11 and the second limit portion 21 being unmated during transportation. In this way, the first inner side wall 1111 and the first side surface 2111 are configured as matching arc surfaces, which can reduce the external force required for the bottom plate 20 to rotate from the first position to the second position, so that after the user completes the assembly, the restriction on the freedom of relative rotation is released and the mounting bracket can be used normally.

[0048] In one embodiment of this implementation, please refer to Figures 4 to 6, the second inner side wall 1112 is an inwardly concave arc surface, and the second side surface 2112 is an outwardly convex arc surface. Specifically, the second inner side wall 1112 and the second side surface 2112 fit together to improve the buffering capacity against vibration and reduce the risk of the first limit portion 11 and the second limit portion 21 being unmated during transportation. In this way, the second inner side wall 1112 and the second side surface 2112 are configured as matching arc surfaces, which can reduce the external force required for the bottom plate 20 to rotate from the first position to the second position, so that after the user completes the assembly, the restriction on the freedom of relative rotation is released and the mounting bracket can be used normally.

[0049] In this embodiment, the first inner wall 1111 and the second inner wall 1112 are both concave arc surfaces, and the first side surface 2111 and the second side surface 2112 are both convex arc surfaces, so that the first limiting portion 11 and the second limiting portion 21 can be released from opposite directions.

[0050] In one embodiment of this implementation, please refer to Figures 4 to 6 The trough body 111 has a first outer side wall 1113 and a second outer side wall 1114 which are opposite to each other in the circumferential direction, and the first outer side wall 1113 is inclined relative to the bottom plate 20 so that the protrusion 211 can slide along the first outer side wall 1113 into the trough body 111, and / or the second outer side surface is inclined relative to the bottom plate 20 so that the protrusion 211 can slide along the first outer side wall 1113 into the trough body 111. With such an arrangement, when it is necessary to transport, the bottom plate 20 can be rotated so that the protrusion 211 slides along the first outer side wall 1113 or the second outer side wall 1114 into the trough body 111, so that the relative rotational freedom of the bottom plate 20 and the rotating plate 10 is limited, so as to facilitate subsequent assembly.

[0051] In one embodiment of this implementation, please refer to Figures 4 to 6 , the groove body 111 has a first end face 1115, and the protrusion 211 has a second end face 2115, and the first end face 1115 and the second end face 2115 are both parallel to the bottom plate 20. Specifically, the first end face 1115 is closer to the bottom plate 20 than the second end face 2115. The first end face 1115 is a semi-annular surface, the inner side edge of the first end face 1115 is connected to the first inner side wall 1111 and the outer side wall, and the outer side edge of the first end face 1115 is connected to the first outer side wall 1113 and the second outer side wall 1114. Both sides of the second end face 2115 are connected to the first side surface 2111 and the second side surface 2112 respectively. In this way, the protrusion 211 can slide along the first end face 1115 to enter or leave the groove body 111.

[0052] In one embodiment of this implementation, please refer to Figure 2 , Figure 3 and Figure 7 , Figure 7 yes Figure 1The cross-sectional view of the connecting member 200 and the rotating chassis assembly 100 at the section passing through the first limit portion 11 and the second limit portion 21.

In this way, the locking member 30 can provide the bottom plate 20 and the rotating plate 10 with a relative degree of freedom of rotation while connecting the bottom plate 20 and the rotating plate 10.

[0053] In this embodiment, the locking member 30 is configured as a screw, the head of the screw abuts against the side of the rotating plate 10 facing away from the bottom plate 20, the shaft of the screw is rotationally engaged with the shaft hole 13, and the end of the shaft away from the head is threadedly engaged with the threaded hole 23 on the bottom plate 20. With this arrangement, the structure of the locking member 30 is relatively simple, and the assembly and disassembly of the bottom plate 20 and the rotating plate 10 are facilitated.

Specifically, in this embodiment, the first limiting portion 11 is configured as a groove body 111. In this way, the first limiting portion 11 and the boss 14 can be connected to form a stronger whole, reducing the risk of failure of the first limiting portion 11 and the second limiting portion 21.

[0055] In one embodiment of this implementation, please refer to Figure 5 The bottom plate 20 is provided with a countersunk hole 24 on one side facing the rotating plate 10, and the boss 14 is received in the countersunk hole 24. Such an arrangement can improve the connection strength between the bottom plate 20 and the rotating plate 10, which is beneficial to improving the supporting capacity of the mounting bracket.
