[0001] The present application relates to the technical field of display screens, and in particular, to a heat-dissipating display screen cabinet. Background Art

[0002] A display screen cabinet is a basic component of an LED display screen. It is usually arranged on the back of a screen body such as a display unit or a unit display board for fixing the screen body and various devices and circuits required for fixing the screen body. The display screen cabinet can be matched with display boards or unit cabinets of different specifications according to different environments and display requirements to meet various application scenarios.

[0003] The utility model patent publication number CN208271488U discloses a display screen cabinet, including: a frame, a power supply box and a strengthening structure. The frame includes a rectangular frame, and the rectangular frame includes two mutually parallel end frames and two mutually parallel side frames; the power supply box is arranged on one side of the frame, the power supply box is provided with a groove, and a cover plate covering the groove is arranged on the groove; the strengthening structure is provided with a support member, the support member is located in the cavity formed by enclosing the rectangular frame and is fixedly connected to the end frame, and the power supply box is fixed on the support member. Compared with the prior art, the support member of the display screen cabinet of the present utility model is arranged in the cavity formed by enclosing the rectangular frame and is fixedly connected to the end frame. Therefore, on the premise of realizing the support and fixation of the LED display screen, no additional space is occupied, and the cabinet can be made thinner and lighter; the power supply box is provided with a groove, and a cover plate covering the groove is arranged on the groove, and a power supply and / or a data receiving and processing module is arranged in the groove. The power supply box is fixed by the frame, and there are fewer contact points with the power supply box. Most of the surface area of the power supply box is in contact with air, so that the heat generated by the power supply box is difficult to dissipate. Summary of the Invention

[0004] In order to solve the problem that the heat of the display screen cabinet is difficult to dissipate due to fewer contact points of the power supply box, the present application provides a heat-dissipating display screen cabinet.

[0005] The heat-dissipating display screen cabinet provided by the present application adopts the following technical solutions:

[0006] A heat-dissipating display screen cabinet includes:

[0007] A mounting plate having a heat-dissipating layer and a conductive layer, the heat-dissipating layer covering the conductive layer. The mounting plate also has several electrical interfaces opened on the surface of the heat-dissipating layer. The electrical interfaces are connected to the conductive layer and can be electrically connected to each other;

[0008] A power supply box including a box body and a power supply port provided on the box body. The power supply port can be connected to the electrical interface. When the power supply box is connected to the mounting plate, the box body is attached to the surface of the heat-dissipating plate layer.

[0009] By adopting the above technical solution, the mounting plate includes a conductive layer and a heat dissipation layer. The heat dissipation layer is disposed on the surface in contact with the power supply box. When the power supply box is connected to the mounting plate, the power supply box can come into wide contact with the heat dissipation layer, thereby dissipating the heat generated during the operation of the power supply box to the outside through the heat dissipation layer. Moreover, the range of the heat dissipation layer is larger than the contact range of the power supply box, thereby increasing the heat dissipation area of the power supply box and improving the heat dissipation effect of the display screen cabinet. The power port is connected to the electrical interface, enabling the power supply box to connect to external lines through the connected electrical interface. Since the power supply box protrudes from the mounting plate, connecting lines from the power supply box will increase the connection space required for the display screen cabinet. By changing the connection position of the line and the display screen cabinet through the electrical interface, the line can be connected within the existing space, reducing the volume of the display screen cabinet after installation and improving the convenience of the display screen cabinet.

[0010] Optionally, the power supply box has multiple power ports, and the power supply box is connected to multiple mounting plates.

[0011] By adopting the above technical solution, due to the relatively large volume of the power supply box, connecting multiple mounting plates can ensure the heat dissipation performance of the power supply box. Moreover, by connecting multiple mounting plates, the power supply box can be connected to multiple electrical interfaces, enabling the power supply box to connect to multiple external lines.

[0012] Optionally, the heat dissipation layer is provided with heat dissipation patterns for increasing the heat dissipation area of the heat dissipation layer.

[0013] By adopting the above technical solution, the heat dissipation patterns can increase the heat dissipation area of the heat dissipation layer, endowing the heat dissipation layer with better heat dissipation performance, thereby improving the working performance of the power supply box.

[0014] Optionally, the mounting plate is further provided with a waterproof cover, which can cover the unused electrical interfaces.

[0015] By adopting the above technical solution, since not every electrical interface needs to be used, the unused electrical interfaces can be sealed by the waterproof cover, thus preventing liquid from entering the mounting plate through the unconnected electrical interfaces and causing damage to the mounting plate.

[0016] Optionally, a waterproof ring is provided at the edge of the waterproof cover for enhancing the waterproof effect.

[0017] By adopting the above technical solution, the waterproof ring can fill the space between the waterproof cover and the electrical interface, thereby improving the sealing performance of the electrical interface when the waterproof cover is closed and preventing liquid from seeping into the mounting plate through the gap of the waterproof cover.

[0018] Optionally, the mounting plate is further provided with fixing posts. The fixing posts are close to the electrical interfaces and are disposed on the surface of the heat dissipation layer for fixing the waterproof cover.

[0019] By adopting the above technical solution, since the electrical interface needs to be kept sealed, setting up additional connection relationships will reduce the sealing performance of the waterproof cover. By providing fixing posts near the electrical interface, the waterproof cover can be fixed when closing the electrical interface.

[0020] Optionally, a connecting frame is further provided, and the connecting frame is respectively connected to the power supply box and the mounting plate.

[0021] By adopting the above technical solution, the connecting frame is used to reinforce the connection between the power supply box and the mounting plate. Since the power supply box and the mounting plate can only be connected through the power port and the electrical interface, the connecting frame can respectively fix the power supply box and the mounting plate, thereby reinforcing the connection between the power supply box and the mounting plate.

[0022] Optionally, the connecting frame is provided with connecting pieces, and the connecting pieces are provided with a power supply box connection hole and a mounting plate connection hole, which are respectively used to connect the power supply box and the mounting plate.

[0023] By adopting the above technical solution, the connecting pieces are respectively connected to the power supply box and the mounting plate through different connection holes, thereby forming the relative fixation of the two, and the stability of the display screen box body can be improved.

[0024] In summary, the present application includes at least one of the following beneficial technical effects:

[0025] 1. The power supply box can come into wide contact with the heat dissipation layer, so that the heat generated during the operation of the power supply box is dissipated to the outside through the heat dissipation layer. And the range of the heat dissipation layer is larger than the contact range of the power supply box, thereby increasing the heat dissipation area of the power supply box and improving the heat dissipation effect of the display screen box body. The power port and the electrical interface are connected, and the connection position of the circuit and the display screen box body is changed through the electrical interface, so that the circuit can be connected within the existing space, reducing the volume of the display screen box body after installation and improving the convenience of the display screen box body;

[0026] 2. Since the power supply box is relatively large in volume, by connecting multiple mounting plates, the heat dissipation performance of the power supply box can be ensured, and by connecting multiple mounting plates, the power supply box can be connected to multiple electrical interfaces, enabling the power supply box to connect multiple external circuits.

Detailed implementation manners

The connecting frame 3 has a connecting piece 31, and the power supply box 2 is fixed in the middle of the connecting frame 3 through the connecting piece 31.

[0035] Referring to Figures 2 to 3 , on one side of the shell of the power supply box 2 close to the mounting plate 1, there are three power supply ports 21, and the power supply ports 21 can be connected to the electrical interface 13. When the power supply box 2 is connected to the mounting plate 1, the box body fits on the surface of the heat dissipation layer 11, and the power supply ports 21 are connected to the electrical interface 13, so as to realize the electrical connection and heat dissipation connection between the power supply box 2 and the mounting plate 1, and the heat generated by the power supply box 2 is quickly dissipated through the heat dissipation layer 11.

[0036] Referring to Figure 4, heat dissipation lines 14 are provided on the surface of the heat dissipation layer 11. The heat dissipation lines 14 can effectively increase the heat dissipation area of the heat dissipation layer 11 and improve the heat dissipation efficiency. Through the optimized design of the heat dissipation lines 14, the display screen can still maintain a good heat dissipation effect during high-load operation, ensuring the stable operation of the display screen. A waterproof cover 15 is provided outside the electrical interface 13. The waterproof cover 15 can cover the unused electrical interface 13, thereby preventing liquid from seeping into the display screen box through these unused electrical interfaces 13 and causing damage. A waterproof ring 16 is provided at the edge of the waterproof cover 15. The waterproof ring 16 is sleeved on the groove at the edge of the waterproof cover 15 and can fill the gap between the waterproof cover 15 and the electrical interface 13, improving the waterproof performance. The setting of the waterproof cover 15 greatly improves the waterproof performance of the display screen box, and the waterproof ring 16 can further improve the sealing effect, thereby providing more comprehensive protection for the display screen box. The mounting plate 1 is also provided with fixing posts 17. The fixing posts 17 are close to the electrical interface 13 and are provided on the surface of the heat dissipation layer 11. The waterproof cover 15 is provided with a mounting portion that cooperates with the fixing posts 17. The waterproof cover 15 is fixedly connected to the fixing posts 17, so that it can be stably fixed outside the electrical interface 13.

[0037] Refer to Figure 5 , the mounting plate 1 has a heat dissipation layer 11 and a conductive layer 12. The heat dissipation layer 11 covers the conductive layer 12 and functions to dissipate heat. The mounting plate 1 is also provided with several electrical interfaces 13. The electrical interfaces 13 are opened on the surface of the heat dissipation layer 11 and are connected to the conductive layer 12, so that the electrical interfaces 13 can be electrically connected to each other.

[0038] Refer to Figure 3 , the connecting frame 3 is provided outside the power supply box 2. The connecting frame 3 includes a plurality of connecting pieces 31 connected to the power supply box 2 and the mounting plate 1. The connecting pieces 31 are respectively provided with a power supply box connecting hole 32 connected to the power supply box 2 and a mounting plate connecting hole 33 connected to the mounting plate 1, which are used to connect the power supply box 2 and the mounting plate 1. By using the connecting frame 3, while simplifying the installation process, the installation firmness is increased, ensuring the stability and reliability of the connection.

[0039] The implementation principle of the embodiment of the present application is as follows: The heat dissipation layer 11 on the mounting plate 1 dissipates heat from the power supply box 2. At the same time, the connection between the power supply port 21 on the power supply box 2 and the electrical interface 13 realizes the connection between the power supply box 2 and the mounting plate 1. The plurality of electrical interfaces 13 are connected to each other through the conductive layer 12, so that the external power supply can be connected to the power supply box through the electrical interface 13 that is not connected to the power supply box 2, thereby providing a stable and reliable working environment for the display screen.
