[0032] As shown in Figures 1 to 13 The embodiment of the present application provides a display device support. The display device support comprises: a base assembly comprising a base 11; a panel assembly 20; a cantilever assembly comprising a support arm 30 and a force transmission member 40, both ends of the support arm 30 are rotationally connected with the base 11 and the panel assembly 20 respectively; an elastic member 12, the elastic member 12 is installed in the base 11, a first end of the force transmission member 40 is arranged in the base 11 and connected with the elastic member 12, and a second end of the force transmission member 40 acts on the support arm 30; an adjusting assembly 50 arranged on the support arm 30, the adjusting assembly 50 is used for moving the second end of the force transmission member 40 on the support arm 30 to adapt to display devices of different weights, and the elastic member 12 provides a support force for keeping the support arm 30 at any position through the force transmission member 40.

[0033] In the technical scheme, the elastic component 12 is arranged in the base 11, one end of the force transmission component 40 is connected with the support arm 30, and the other end of the force transmission component 40 is arranged in the base 11 and connected with the elastic component 12, the layout of the conventional display device support that the elastic element is arranged in the support arm 30 can be changed, so that the volume and length of the support arm 30 can be reduced, the support arm 30 is more compact, and the support arm 30 is particularly suitable for use in a limited space environment, such as a room with a low ceiling, and the like, and the use experience of the user can be improved.

[0034] Further, by the position of the second end of the force transmission component 40 on the support arm 30, the position of the action point of the elastic component 12 on the support arm can be changed, so that the user can easily adjust the bearing state of the support according to the different weight and size of the display device, and the use experience of the user is improved.

[0035] Preferably, in the embodiment of the utility model, the elastic component 12 is a mechanical spring, and the mechanical spring is vertically installed in the base 11.

[0036] As shown in Figure 3 In the embodiment of the utility model, the base assembly further includes at least one guide component 13, the guide component 13 is rotatably arranged in the base 11, and the force transmission component 40 is arranged around the at least one guide component 13.

[0037] Through the above arrangement, the force transmission component 40 can be ensured to move smoothly along the predetermined path during force transmission, so that the efficiency and stability of force transmission are improved.

[0038] Further, the guide component 13 is arranged in the force transmission path, the guide component 13 can support the force transmission component 40 to reduce the direct friction between the force transmission component 40 and other parts of the support, especially when moving and the bearing changes. This not only reduces the wear rate, but also effectively prolongs the service life of the entire support.

[0039] As shown in Figure 3 and Figure 6 In the embodiment of the utility model, the base assembly includes a plurality of guide components 13, at least two guide components 13 are arranged in a staggered manner from the base 11 to the panel assembly 20, the force transmission component 40 is sequentially arranged around the at least two guide components 13, and the first guide component 13 in the at least two guide components 13 is located below the elastic component 12.

[0040] In the technical solution, the misaligned guide members 13 ensure that the force transmission member 40 can smoothly bypass each guide member 13 during force transmission, thereby ensuring uniform distribution of force, which helps to improve the responsiveness and efficiency of the elastic member 12 and ensures that the display is uniformly stressed during lifting, avoiding instability and potential damage caused by local excessive stress.

[0041] Further, the first guide member 13 is arranged below the elastic member 12, which can optimize the space layout in the entire base to more effectively utilize the internal space of the base. This layout can reduce the volume of the cantilever assembly and make the support more compact, which is suitable for use in limited space, such as wall-mounted installation in narrow rooms or work areas.

[0042] Further, the misaligned guide members 13 help to enhance the structural stability of the entire support. By reasonably distributing the positions of the guide members 13, the force state of the cantilever assembly can be more balanced when the support bears displays of different weights, avoiding stability problems caused by structural imbalance.

[0043] Preferably, in the embodiments of the utility model, the number of guide members 13 is two, the first guide member 13 of the two guide members 13 is below the elastic member 12, the second guide member 13 of the two guide members 13 is above the first guide member 13, and the second guide member 13 is on the side of the elastic member 12 facing the panel assembly 20.

[0045] As shown in Figure 5 and Figure 6 In the embodiments of the utility model, the guide member 13 includes at least one sprocket, and the force transmission member 40 includes at least one chain.

[0046] In the technical solution, the cooperation of the chain and the sprocket can ensure smooth and efficient transmission of force.

[0047] Further, the arrangement of the sprocket and the chain makes the position adjustment of the force transmission member 40 more simple. When adjusting the load state of the display, the chain can more accurately control the pre-tightening force of the elastic member 12, and the sprocket serves as a guide to ensure that the chain does not derail during adjustment.

[0088] Specifically, in this embodiment of the invention, the operating end 55 is an internal hexagonal hole located on the first gear 541, and the adjusting tool can be a wrench. When the wrench passes through the lower connecting arm 35 and acts on the first gear 541, the second gear 542 rotates, causing the adjusting member 51 to rotate. This allows the moving member 52 to slide axially on the adjusting member 51, and the corresponding indicator bar points to the weight scale to realize the load-bearing range of the bracket. The clearance hole 33 is located on the lower surface of the lower connecting arm 35, which is appropriately positioned, provides ample adjustment space, and is relatively convenient.

[0089] In one embodiment, the adjustment component 50 may also be mounted on the upper connecting arm 34.

[0090] like Figure 3 As shown in the embodiment of this utility model, the base assembly further includes a connector 14, which is disposed on the base 11, and the end of the elastic member 12 away from the force transmission member 40 is connected to the connector 14.

[0091] With the above configuration, the elastic member 12 can be fixed to the base 11 by the connector 14, which can ensure the stability and firmness of the elastic member 12 when bearing the weight of the display device, avoid the structural loosening or instability problems that may be caused by direct connection, and improve the structural safety of the entire bracket.

[0092] Specifically, in the embodiments of this utility model, the connector 14 is a connecting shaft, and the connecting shaft is provided with an annular limiting groove. The elastic member 12 is hooked on the annular limiting groove. In this way, the elastic member 12 can be prevented from moving along the axis of the connecting shaft, thereby improving the support stability of the elastic member 12.

[0093] Specifically, in the embodiment of the present application, when pulling the display device downward, the lower connecting arm 35 rotates, and the chain acts on the elastic member 12 by passing around the sprocket, thereby stretching the elastic member 12, and the elastic force generated by the elastic member 12 offsets the gravity of the display device. When matching display devices of different weights, the position of the moving member 52 is changed by adjusting the adjusting member 51. Because the chain connects the elastic member 12 and the moving member 52, on the one hand, the initial stretching amount of the elastic member 12 can be changed, and on the other hand, the point of action of the elastic force generated by the elastic member 12 on the lower connecting arm 35 through the chain rope, that is, the force arm of the elastic force on the rotation of the lower connecting arm 35 can be changed. Since the adjustment will change the initial elastic force and the force arm at the same time, it can better match the display of different weights, and the lifting experience is better.

[0094] As Figure 2 shown, in the embodiment of the present application, the panel assembly 20 includes a panel connecting piece 21 and a panel 22, the support arm 30 is connected with the panel 22 through the panel connecting piece 21, the panel 22 has a hanging arm for installing a television set, the base assembly is connected with a wallboard assembly, and the wallboard assembly is used for being installed on a wall. The wallboard assembly includes an upper wallboard 1 and a lower wallboard 2.

[0095] From the above description, it can be seen that the above-mentioned embodiments of the present application achieve the following technical effects: the elastic member is placed in the base, one end of the force transmission member is connected with the support arm, and the other end of the force transmission member is arranged in the base and connected with the elastic member. The layout of the elastic element in the support arm of the traditional display device support can be changed, thereby the volume and length of the support arm can be reduced, the support arm is more compact, and it is particularly suitable for use in limited space environment, such as a room with low ceiling, and the user's use experience can be improved.

[0096] The above only describes the preferred embodiments of the present application and is not used to limit the present application. For those skilled in the art, the present application can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
