[0004] Existing foldable LED displays on the market have drawbacks such as non-adjustable height and inflexible rotation of their supports, which cause some inconvenience for users in displaying and controlling them.

[0005] Therefore, a foldable LED display screen bracket structure is proposed to address the above problems. Utility Model Content

[0006] To overcome the shortcomings of existing technologies and address the drawbacks of existing foldable LED displays on the market, such as their non-adjustable height and inflexible rotation, which cause inconvenience to users in displaying and controlling them.

[0007] The technical solution adopted by this utility model to solve its technical problem is as follows: The foldable LED display screen bracket structure of this utility model includes a support plate, a height adjustment self-locking component is installed on the top of the support plate, and a foldable support component is installed on the top of the height adjustment self-locking component; the height adjustment self-locking component includes a bottom support shell, a second bearing is fixedly connected inside the bottom support shell, and a threaded rod is fixedly connected inside the second bearing; a slider is rotatably connected to the top of the threaded rod, and a worm gear is fixedly connected to the threaded rod; a worm is meshed on the side of the worm gear, and a first bearing is fixedly connected to the bottom end of the worm; a motor is installed at the top of the worm; a nut block is provided on the top of the worm gear, and a top support shell is fixedly connected to the side of the nut block; and a first sliding groove is opened inside the top support shell.

[0008] Preferably, the threaded rod forms a rotating structure with the bottom support shell via the second bearing, and the worm gear forms a rotating structure with the bottom support shell via the first bearing. The top support shell forms a lifting structure with the bottom support shell via the nut block, the threaded rod, and the nut block.

[0009] Preferably, the motor has a transmission structure consisting of a worm, a worm wheel, and a threaded rod, with the worm and the worm wheel meshing with each other.

[0010] Preferably, the foldable support assembly includes a support frame, a hinge is fixedly connected to one side of the support frame, a left support is fixedly connected to the other side of the hinge, a rotating rod is fixedly connected to the bottom of the support frame, a right support is provided on the other side of the support frame, and a limit bar is fixedly connected to the bottom of the right support.

[0011] Preferably, the right-side bracket is connected to the support frame via a hinge to form a rotating structure, and both the support frame and the right-side bracket are made of aluminum alloy.

[0012] Preferably, the left bracket is connected to the support frame via a hinge to form a rotating structure, and the right bracket is made of aluminum alloy.

[0013] The advantages of this utility model are:

[0014] 1. This utility model features a height-adjustable self-locking component. The bracket is driven by a motor-driven transmission system consisting of a worm gear, worm wheel, and threaded rod, enabling electric adjustment of the support plate height. Compared to traditional manual adjustment methods, this significantly reduces the burden of manual operation, making it particularly suitable for large or high-mounted LED displays. Operators only need to start the motor to quickly and accurately adjust the display to the appropriate height, greatly improving operational efficiency. The worm gear mechanism has a reverse self-locking characteristic; when the motor stops working, the worm gear cannot drive the worm wheel to reverse, and the threaded rod cannot rotate on its own, keeping the display stably at the set height. This self-locking function effectively prevents changes in display height caused by accidental collisions or vibrations, ensuring safety and stability during use. The bottom and top support shells are connected by a threaded rod and nut block, forming a stable vertical support structure. Simultaneously, the cooperation between the slider and the first sliding groove not only assists in supporting the top support shell but also acts as a guide during lifting, preventing the support shell from swaying or shifting, further enhancing the overall stability of the bracket.

[0015] 2. This utility model features a foldable support assembly. This assembly connects the left and right supports to the support frame via hinges, allowing for easy multi-angle rotation and folding. Whether the left and right supports are brought towards the support frame horizontally, or folded at a specific angle using the rotating rod, it is extremely convenient. This feature significantly reduces the space occupied by the support frame in its folded state, facilitating rapid transport and storage during performances, exhibitions, and other events, significantly improving the practicality and flexibility of the support frame. The limiting bar at the bottom of the right support frame precisely limits the rotation angle of the right support frame during unfolding, ensuring the support frame is fully unfolded and maintains a stable support state. This prevents the display screen from tilting or the support frame from becoming unbalanced due to improper unfolding angles, providing strong safety assurance during use. The support frame and the right support frame are made of aluminum alloy. Aluminum alloy has low density and high strength, reducing the overall weight of the support frame while ensuring sufficient load-bearing capacity to easily handle the weight of the LED display screen, preventing deformation or damage due to insufficient material strength. At the same time, aluminum alloy has good corrosion resistance, effectively resisting the erosion of harsh environments such as humidity and acids / alkalis, extending the service life of the support frame.

[0023] Example 1

[0024] like Figure 1 The foldable LED display bracket structure shown includes a height-adjustable self-locking component 1, a foldable support component 2, and a support plate 3.

[0025] Please see Figure 1 and Figure 4The diagram illustrates a foldable LED display screen bracket structure, comprising a support plate 3, a height-adjustable self-locking assembly 1 mounted on the top of the support plate 3, and a foldable support assembly 2 mounted on the top of the height-adjustable self-locking assembly 1. The height-adjustable self-locking assembly 1 includes a bottom support shell 101, a second bearing 104 fixedly connected inside the bottom support shell 101, a threaded rod 106 fixedly connected inside the second bearing 104, a slider 108 rotatably connected to the top of the threaded rod 106, a worm gear 105 fixedly connected to the threaded rod 106, a worm 102 meshing with the side of the worm gear 105, a first bearing 103 fixedly connected to the bottom end of the worm 102, and the top end of the worm 102... A motor 111 is installed, a nut block 107 is provided on the top of the worm gear 105, and a top support shell 110 is fixedly connected to the side of the nut block 107. The top support shell 110 has a first sliding groove 109 inside. The threaded rod 106 forms a rotating structure with the bottom support shell 101 through the second bearing 104, and the worm 102 forms a rotating structure with the bottom support shell 101 through the first bearing 103. The top support shell 110 forms a lifting structure with the nut block 107, the threaded rod 106 and the bottom support shell 101. The motor 111 forms a transmission structure with the worm 102, the worm gear 105 and the threaded rod 106, and the worm 102 and the worm gear 105 mesh with each other.

[0026] Please see Figure 4 The diagram shows a foldable LED display bracket structure. The foldable support component 2 includes a support frame 201. A hinge 205 is fixedly connected to one side of the support frame 201, and a left support 206 is fixedly connected to the other side of the hinge 205. A rotating rod 204 is fixedly connected to the bottom of the support frame 201, and a right support 202 is provided on the other side of the support frame 201. A limit rod 203 is fixedly connected to the bottom of the right support 202. The right support 202 and the support frame 201 form a rotating structure through the hinge 205. Both the support frame 201 and the right support 202 are made of aluminum alloy. The left support 206 and the support frame 201 form a rotating structure through the hinge 205. The right support 202 is also made of aluminum alloy.

[0027] Working principle: This foldable LED display stand is designed to achieve height adjustment and convenient folding to meet diverse usage needs. Its working process revolves around the height adjustment self-locking component 1 and the foldable support component 2.

[0028] When the height of the bracket needs to be adjusted, the motor 111 is started. The motor 111 drives the worm gear 102 to rotate. Since the worm gear 102 meshes with the worm wheel 105, the worm wheel 105 rotates accordingly. The worm wheel 105 is fixed on the threaded rod 106, which in turn drives the threaded rod 106 to rotate around the second bearing 104 within the bottom support shell 101. During the rotation of the threaded rod 106, it undergoes threaded transmission with the nut block 107, and the nut block 107 moves axially along the threaded rod 106. Because the nut block 107 is fixedly connected to the top support shell 110 on its side, the top support shell 110 forms a lifting structure with the bottom support shell 101 through the nut block 107, the threaded rod 106, and the nut block 107, achieving raising or lowering. At the same time, the slider 108 rotatably connected to the top of the threaded rod 106 slides within the first groove 109 of the top support shell 110, playing a guiding and auxiliary support role, ensuring the smooth raising and lowering of the top support shell 110. In addition, the reverse self-locking characteristic of the worm gear 105 and worm 102 mechanism allows the bracket to be stably maintained at the set height after the motor 111 stops working.

[0029] During the folding operation, the right bracket 202 and the left bracket 206 can rotate around the hinge 205 connected to the support frame 201. When the right bracket 202 rotates, the bottom limiting bar 203 restricts its rotation angle, ensuring smooth folding. The support frame 201 can also rotate around the bottom rotating rod 204. Through the coordinated operation of these components, the foldable support assembly 2 can be folded flexibly. When unfolding the bracket, the operation process is reversed, and each component resets according to its corresponding principle, providing stable support for the LED display screen.

[0030] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
