The size, shape, and layout of the heat dissipation holes 3b are determined according to the direction of airflow to achieve optimal heat exchange efficiency while avoiding weakening the mechanical strength of the slot bottom due to excessively large holes. The spacing of the heat dissipation holes 3b ensures that the heat of the power module 22 unit within the receiving slot 3a can be evenly distributed, reducing the formation of hot spots and extending the service life of the power module 22 unit.

[0031] In the embodiment of the present utility model, as Figure 3 As shown, the power cover 3 has a shielding portion 3c and an extension portion 3d. The shielding portion 3c shields the power module 22, and the extension portion 3d is located at the periphery of the shielding portion 3c. The extension portion 3d is protruding from the edge of the power module 22.

[0032] In one embodiment, the power cover 3 comprises two main components: a shielding portion 3c and an extension portion 3d. The shielding portion 3c is the core component of the power cover 3. Its size and shape are tailored to cover the power module 22, ensuring that the power module 22 is completely shielded, thereby providing the necessary fire protection and physical protection. The extension portion 3d is designed around the perimeter of the shielding portion 3c, forming an outwardly extending structure that surrounds the side walls of the power module 22 and extends outward for a certain distance. Specifically, the left and right ends of the extension portion 3d extend at least 13 mm beyond the battery side edges in the width direction. In terms of height, the top of the extension portion 3d protrudes at least 50 mm above the battery, while the bottom extends as close as possible to the bottom of the backplane cover 1 to maximize coverage. This extension design not only enhances the structural integrity of the power cover 3 but also provides additional fire protection. The extension portion 3d's length is precisely calculated to ensure that it does not interfere with the proper heat dissipation of the power module 22, while maintaining an appropriate clearance from other components within the receiving slot 3a to prevent short circuits or wear caused by contact. With this design, the power cover 3 ensures the safety of the power module 22 while also taking into account the convenience of maintenance and overall aesthetics.

[0033] In the embodiment of the present utility model, as Figure 3 and Figure 4 As shown, the power cover 3 is provided with a top mounting plate 32 and a bottom mounting plate 33 , which are respectively connected to the power cover 3 , and are respectively detachably connected to the back plate 21 .

[0034] In one embodiment, the power cover 3 includes a top mounting plate 32 and a bottom mounting plate 33.

The top mounting plate 32 and the bottom mounting plate 33 are firmly connected to the back plate 21 by a detachable connection method such as bolts or snaps, ensuring that the power cover 3 can enclose a receiving groove 3a with the back plate 21 to place and protect the power module 22, thereby improving the safety and stability of the overall structure. This structural design also takes thermal management into consideration, ensuring that the heat generated by the power module 22 during operation can be dissipated through the receiving groove 3a of the power cover 3 to avoid overheating. The power cover 3 not only provides physical and fire protection for the power module 22, but also improves the convenience of maintenance through a detachable connection mechanism, meeting the requirements of modern display devices for safety, reliability and ease of maintenance.

[0035] In the embodiment of the present utility model, as Figure 4 and Figure 5 As shown, a plurality of anti-vibration bosses 35 are formed on one side of the top mounting plate 32 and the bottom mounting plate 33 close to the display module 2 , and the anti-vibration bosses 35 are arranged at intervals.

[0036] In this embodiment, to enhance the stability of the power cover 3 and prevent it from vibrating and becoming loose during operation, multiple anti-vibration bosses 35 are designed on the side of the top mounting plate 32 and the bottom mounting plate 33 near the display module 2. These anti-vibration bosses 35 are arranged at intervals to minimize the potential impact of vibration on the power cover 3 without affecting the heat dissipation of the power module 22 or interfering with electronic signal transmission.

[0037] Each anti-vibration boss 35 adopts an optimized structural design and may be cylindrical, conical or other shapes suitable for absorbing and dissipating vibration energy. Their height and rigidity are specially selected to adapt to vibrations of different frequencies while maintaining sufficient elasticity to absorb shocks, thereby preventing the power cover 3 from vibrating and loosening during operation. The spacing between the anti-vibration bosses 35 not only ensures the integrity and strength of the structure, but also allows proper air circulation, which helps to dissipate heat. This design not only improves the overall stability and durability of the display device, but also helps to maintain the long-term reliability and performance of the power module 22, meeting the high-standard vibration and shock protection requirements of industrial and consumer electronic products.
