Description

Technical Field

[0001] This utility model relates to the field of display technology, specifically to a display back cover structure with an integrated heat dissipation module. Background Technology

[0002] As display technology rapidly advances towards larger sizes, higher resolutions, and higher refresh rates, the power density of monitors continues to increase, generating significant heat during operation, particularly in the core component, the display screen itself. Simultaneously, the application scenarios for monitors are expanding from indoor office environments to complex environments such as outdoor spaces, industrial workshops, and automotive applications. These scenarios not only place higher demands on the monitor's heat dissipation performance but also require it to withstand external environmental challenges such as vibration, impact, and rain. However, the traditional monitor back cover structures currently on the market have significant shortcomings in terms of heat dissipation efficiency, protective performance, and display screen stability, making them insufficient to meet the needs of new monitors. The main technical pain points are as follows: Traditional monitor back covers mostly adopt a "passive heat dissipation" design, which dissipates heat only through a few ventilation holes in the back cover body or simple protrusions on the back cover surface. They lack active heat dissipation mechanisms and efficient heat conduction paths. In addition, traditional back covers are not optimized for heat conduction. The heat generated by the display body can only be naturally conducted to the back cover through the contact surface. The heat conduction efficiency is low, which leads to excessively high temperature in some areas of the display, forming "hot spots" and affecting the overall working stability of the monitor.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a display back shell structure with an integrated heat dissipation module, comprising a back shell, a transparent protective plate, a positioning mechanism, and a heat dissipation shroud. The display screen body is installed inside the back shell, the transparent protective plate is disposed inside the back shell on one side of the display screen body, the positioning mechanism is installed on both side walls of the back shell, the heat dissipation shroud is fixed on the outer wall of the back shell, and heat dissipation mesh windows are installed on both side walls of the heat dissipation shroud, and a cooling fan is installed inside the heat dissipation shroud.

[0005] Furthermore, a rainproof eave is installed at the top of the rear housing.

[0006] Furthermore, the inner wall of the rear housing is covered with equally spaced rubber pads, which are tightly fitted to the outer wall of the display screen body.

[0007] Furthermore, the outer wall of the rear housing is provided with equally spaced heat dissipation holes.

[0008] Furthermore, a heat-conducting plate is installed on the outer wall of the display screen body on the side away from the transparent protective plate, and the surface of the heat-conducting plate is fixed with heat sinks at equal intervals, with one end of the heat sinks extending into the interior of the heat sink cover.

The extended part of the positioning plate 406 is used to contact a specific position of the transparent protective plate 5 to achieve the positioning function.

[0044] In this embodiment of the application, the following steps are taken: First, confirm that the inner wall of the rear housing 1 is clean and free of impurities. Then, use an adhesive to evenly stick the rubber pads 8 at equal intervals to the designated positions on the inner wall of the rear housing 1, ensuring that the rubber pads 8 are firmly attached and the surface is flat. Next, fix the rainproof eaves 3 to the top of the rear housing 1 with buckles or screws, and adjust the angle of the rainproof eaves 3 so that its front end is slightly tilted downwards to form an effective shield. After this is completed, the basic protective components of the housing 1 are pre-installed.

[0045] Place the display body 2 inside the rear housing 1, ensuring that the rubber pads 8 on the outer and inner walls of the display body 2 fit tightly together. Secure the display body 2 to the inner wall of the rear housing 1 with screws, ensuring that the display body 2 is secure and does not loosen. Next, attach the heat-conducting plate 9 to the outer wall of the display body 2 on the side away from the transparent protective plate 5, and secure it with thermal adhesive or screws. Then, fix the heat sinks 10 at equal intervals to the surface of the heat-conducting plate 9, ensuring that one end of the heat sink 10 extends to the pre-set opening on the outer wall of the rear housing 1, in preparation for the subsequent connection of the heat sink cover 6.

[0046] Take the transparent protective plate 5 and align it with the installation position on one side of the display screen body 2 inside the rear housing 1. Slowly push it into the rear housing 1 so that the edge of the transparent protective plate 5 fits tightly against the inner wall of the rear housing 1. Then, use the positioning mechanism 4 to accurately position the transparent protective plate 5. Use a tool to rotate the anti-theft bolt 403 on the outside of the positioning cover 401, which will drive the threaded rod 402 inside the positioning cover 401 to rotate. The threaded slider 404 on the outer wall of the threaded rod 402 moves along the axial direction of the threaded rod 402, and then pushes the positioning plate 406 through the cross arm 405 so that one end of the positioning plate 406 passes through the rear housing 1 and fits against the surface of the transparent protective plate 5 until the transparent protective plate 5 is stably clamped. After the positioning is completed, stop rotating the anti-theft bolt 403. The characteristics of the anti-theft bolt 403 are used to prevent unauthorized disassembly.

[0047] Align the heat sink 6 with the extension end of the heat sink 10 on the outer wall of the rear housing 1, so that one end of the heat sink 10 is completely inserted into the heat sink 6. Fix the heat sink 6 to the outer wall of the rear housing 1 with screws. Then check whether the heat dissipation mesh 7 on both sides of the heat sink 6 is intact and ensures that there is no blockage. Then install the cooling fan 12 in the preset position inside the heat sink 6 through the fixing bracket. Lead out the power cord of the cooling fan 12 through the preset wire hole on the heat sink 6 for easy connection to an external power source later.

[0048] After assembling all components, check whether the heat dissipation holes 11 on the outer wall of the rear housing 1 are unobstructed and ensure that there is no dust or foreign matter blocking them; connect the power cord of the cooling fan 12 to the external power supply and start the monitor. At this time, the heat generated by the display body 2 is conducted to the heat sink 10 through the heat conduction plate 9. The cooling fan 12 runs to accelerate the airflow inside the heat sink 6, and the heat is discharged through the heat dissipation mesh 7. At the same time, the heat dissipation holes 11 of the rear housing 1 assist the air convection, further improving the heat dissipation effect; when used outdoors, the rainproof eaves 3 prevent rainwater from entering, the rubber pads 8 buffer vibration and seal gaps, and the transparent protective plate 5 protects the display body 2 from physical impact and contamination, ensuring stable operation of the monitor; if maintenance is required, simply disassemble the corresponding parts to repair or replace the internal components.
