Description

Technical Field

[0001] The present invention belongs to the field of displays, and more particularly, to a display screen bracket. Background Art

[0002] In the prior art, an LED display screen is a widely used large display device. It is applied to various occasions that require large-area image display, such as large-scale gatherings, performances, virtual scenes, etc. The large-area LED display screen is assembled by splicing a lot of display units, and each display unit is a standardized module. Each display unit requires a bracket to install the LED display component and the control component on the bracket to form a functional unit. Currently, most of these brackets adopt a frame structure made of cast aluminum material.

[0003] The area of the LED display screen is very large. Usually, the screen erected in a gathering and performance venue can be as high as 20 meters, with an area close to 1,000 square meters and thousands of display units are used. The current cast aluminum structure bracket is relatively heavy, which makes the labor intensity of workers during erection very high. Moreover, the height dimension of the LED display screen is restricted by the weight. When in a suspended state, the screen area is even more restricted by the weight. Therefore, it is necessary to reduce the weight of the bracket. Due to the material properties and process limitations of the cast aluminum structure, it has reached its limit, and lighter and stronger materials need to be used for replacement, which are composite materials, including resin-based carbon fiber composite materials and resin-based glass fiber composite materials. The specific strength and specific stiffness of these two materials are superior to those of aluminum. It can achieve weight reduction while maintaining the strength of the bracket.

[0004] However, the manufacturing process of composite materials is very different from that of cast aluminum. The existing bracket design concept is based on cast aluminum materials. Composite materials are difficult to manufacture. Even if they are manufactured by imitating the existing structure, the cost is very high and the production efficiency is very low, making large-scale production impossible.

[0005] In view of this, the present invention is specifically proposed. Summary of the Invention

[0006] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide a display screen bracket.

[0007] To solve the above technical problem, the basic concept of the technical solution adopted by the present invention is: a display screen bracket, including an outer frame plate, the outer frame plate is provided with a plurality of mounting plates at intervals along the second direction, the plurality of mounting plates are used for mounting display units, a honeycomb support assembly is provided between each adjacent mounting plate and the outer frame plate, and between adjacent mounting plates, and both the outer frame plate and the mounting plates are made of carbon fiber material.

[0008] In the present invention, both the outer frame plate and the mounting plate are made of carbon fiber material, thereby effectively reducing the overall weight of the display screen bracket, and solving the problem in the prior art that the laying area of the display screen is limited due to weight constraints.

[0009] In one embodiment, the plurality of mounting plates include a plurality of first mounting plates and at least two second mounting plates. The first mounting plates are used to mount the display screen, and a detachable connection structure is provided between the first mounting plates and the display screen.

[0010] The two second mounting plates are arranged oppositely, and the two second mounting plates and the outer frame plate enclose a receiving space for mounting the control box of the display screen.

[0011] By forming the receiving space through the cooperation of the second mounting plate and the outer frame plate and mounting the control box of the display screen in the receiving space, interference between the mounting plate and the display screen can be avoided.

[0012] In one embodiment, the plurality of first mounting plates are all arranged between the second mounting plate and the outer frame plate.

[0013] The first mounting plate has a first end face and a second end face arranged oppositely. The first end face faces the third direction. Along the third direction, two spaced-apart first mounting plates are provided, and the honeycomb support assembly is arranged between the two spaced-apart first mounting plates.

[0014] By arranging the first support member and the second support member between the two first mounting plates, a good support effect can be provided for the first mounting plate, and a stable mounting state can be ensured when the display screen is mounted on the first mounting plate.

[0015] In one embodiment, the honeycomb support assembly includes a first support member, a second support member, and a third support member.

[0016] A plurality of first support members are provided between the outer frame plate and the first mounting plate. The plurality of first support members are adjacent to each other along the first direction. A plurality of second support members are provided between the second mounting plate and the first mounting plate. A plurality of third support members are provided between the two oppositely arranged second mounting plates.

[0017] The plurality of first support members and the plurality of second support members are adjacent to each other along the first direction, and the first mounting plate is located at the connection position between the plurality of first support members and the plurality of second support members.

[0018] The first mounting plate is disposed at the connection position of the first support member and the second support member, which can further improve the structural strength of the first mounting plate. At the same time, the mutual connection between the first mounting plate, the first support member and the second support member can further improve the connection stability between each structure and enhance the structural strength of the display screen bracket.

[0019] In one embodiment, the honeycomb support assembly is a hollow polygonal or circular structure, and the honeycomb support assembly is made of carbon fiber or glass fiber material.

[0020] On the basis that both the outer frame plate and the mounting plate are made of carbon fiber material, the honeycomb support assembly also adopting carbon fiber material or glass fiber material can further reduce the weight of the display screen bracket and reduce the restriction of the display screen weight on the laying area of the display screen.

[0021] In one embodiment, at least one first positioning plate protrudes from the second mounting plate in the opposite direction of the third direction. A handle rod is provided on the first positioning plate, and the handle rod penetrates through the first positioning plates of the two second mounting plates at the same time.

[0022] In one embodiment, the plurality of positioning plates include two second positioning plates, which are respectively disposed at both ends of the second mounting plate along the first direction, and the third support member is disposed between the two second positioning plates.

[0023] By providing the first positioning plate and the second positioning plate on the second mounting plate, the first positioning plate is used to install the handle rod to provide a handle position during the process of laying the display screen, thereby improving the installation efficiency of the display screen. At the same time, the second positioning plate is used to install the third support member. Among them, both the first positioning plate and the second positioning plate protrude in the opposite direction of the third direction, so as to avoid interference of the handle rod and the third support member with the control box of the display screen.

[0024] In one embodiment, a plurality of mounting holes are provided on the outer frame plate, and the mounting holes are used to install locks;

[0025] When two display screen brackets are connected, a lock is provided on the mounting hole of one of the display screen brackets, and the lock is used to connect the outer frame plates of the two display screen brackets.

[0026] In one embodiment, the lock includes a positioning member and a flipping mechanism. A plug for inserting into the mounting hole is provided on the positioning member. The flipping mechanism is hingedly connected to the positioning member, and a positioning post is provided on the flipping mechanism;

[0027] Threads are provided on the outer circumferential wall of the plug, and a threaded through hole matching the thread of the plug is provided on the positioning post. The positioning post can rotate freely on the flipping mechanism.

[0028] By providing a lock on the outer frame plate, the connection structure between the display screens is kept stable. At the same time, the adjacent outer frame plates are in contact with each other, so that while improving the structural strength of the outer frame plate, the connection stability between the outer frame plates can be ensured.

[0029] In one embodiment, a corner connector is provided at the connection position between the adjacent outer frame plates.

[0030] After adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art.

[0031] 1. In the present invention, the structural strength of the display screen bracket is improved through the honeycomb support component, so as to realize the large-area laying of the LED display screen, and the structural strength of the display screen bracket can meet the laying requirements of the LED display screen.

[0032] 2. The honeycomb support component is made of carbon fiber material or glass fiber material, which can ensure the structural strength of the display screen bracket while reducing the excessive increase in the weight of the display screen bracket, and can meet the requirements of large-area laying of the LED display screen.

[0033] 3. Making the outer frame plate, the first mounting plate and the second mounting plate all made of carbon fiber material can further reduce the structural strength of the display screen bracket. Compared with the existing cast aluminum frame, while ensuring the structural strength of the display screen bracket, the self-weight of the display screen bracket is greatly reduced.

[0034] 4. The second mounting plate forms a receiving space for accommodating the control box, ensuring that the display unit can be smoothly installed on the display screen bracket. At the same time, adjusting the distance between the two relatively arranged second mounting plates can form a good limiting structure for the control box, ensuring the installation stability of the display unit on the display screen.

[0035] 5. The lock provided on the outer frame plate can play a good fixing effect when the display screen brackets are connected to each other, and is convenient for disassembly.

Detailed implementation manners

[0053] To make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention, but are not used to limit the scope of the present invention.

It is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present invention.

[0055] In the description of the present invention, it should be noted that unless otherwise clearly specified and defined, the terms "mounted", "connected", and "coupled" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0056] A display screen bracket of the present invention includes an outer frame plate 1. The outer frame plate 1 is provided with a plurality of mounting plates 2 at intervals along the second direction. A honeycomb support assembly 3 is provided between each adjacent mounting plate 2 and the outer frame plate 1, and between adjacent mounting plates 2. The outer frame plate 1 and the mounting plates 2 are made of carbon fiber material.

[0057] For the convenience of description, in the embodiments of the present application, a coordinate system established by three mutually perpendicular first direction, second direction, and third direction is used to describe the display screen bracket. The extension direction of the first mounting plate 210 is taken as the first direction (the direction indicated by the arrow X in the figure), and the other two directions are the second direction (the direction indicated by the arrow Y in the figure) and the third direction (the direction indicated by the arrow Z in the figure), respectively.

[0058] Figure 1 is a schematic diagram of the display screen bracket of the present invention. Refer to Figure 1 , in the process of using this embodiment, by providing a honeycomb support assembly 3 between the outer frame plate 1 and the plurality of mounting plates 2, and between the plurality of mounting plates 2, the display screen bracket composed of the outer frame plate 1, the mounting plates 2, and the honeycomb support assembly 3 can provide a good support effect for the display.

[0059] At the same time, in order to avoid the weight increase of the display screen bracket caused by adding the honeycomb support assembly 3 to the display screen bracket, the honeycomb support assembly 3 is made of carbon fiber material or glass fiber material, thereby avoiding excessive increase in the overall weight of the display screen bracket. Further, the outer frame plate 1 and the mounting plates 2 can both be made of carbon fiber material, thereby effectively reducing the overall weight of the display screen bracket. Even after adding the honeycomb support assembly 3, the overall weight of the display screen bracket is lighter than that of the display screen bracket made of cast aluminum material, thereby reducing the problem that the area of the display is limited due to the weight of the display screen bracket.

[0060] It should be noted that the existing display brackets are usually made of cast aluminum. Although replacing the material can reduce the weight, the existing structure of the display bracket makes it difficult to manufacture a display bracket with the same structure using carbon fiber material. Therefore, the inventor designs the outer frame plate 1 and the mounting plate 2 as plate-like structures, so as to reduce the weight of the display bracket while ensuring the structural strength of the display bracket, and at the same time improve the production efficiency to meet the requirements of mass production.

[0061] Optionally, the mounting plate 2 includes a plurality of first mounting plates 210 and at least two second mounting plates 220. The display unit includes a display screen and a control box.

[0063] In the existing display unit, a control box is usually provided on the back plate of the display screen. In order to avoid interference between the mounting plate 2 and the control box, the two second mounting plates 220 are arranged at intervals along the first direction, and cooperate with the outer frame plate 1 to form a receiving space 230 for receiving the control box; further, the spacing distance between the second mounting plates 220 is matched with the size of the control box, so that the second mounting plates 220 can form a good limiting effect on the control box and provide a good supporting effect for the control box and the display unit.

[0064] Continue to refer to Figure 1 , optionally, the outer frame plate 1 encloses a frame structure, the receiving space 230 is located inside the frame structure, and a plurality of first mounting plates 210 are all arranged between the second mounting plates 220 and the outer frame plate 1;
