[0002] LED backlighting is a backlighting technology that uses light-emitting diodes as the light source. LED backlighting is often fixed with screws, which is inconvenient to install and remove. Moreover, fixing with screws can damage the side plate of the LED backlighting and easily cause cracks. To better solve this problem, we propose an LED backlighting installation structure. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing technologies by proposing an LED backlight mounting structure.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] An LED backlight mounting structure includes a base shell, an LED backlight body is snapped into the port of the base shell, and a pressure cover for fixing the LED backlight body is installed on the port of the base shell via a quick-release assembly.

[0006] Preferably, the cap has a frame-like structure.

[0007] Preferably, the quick-release assembly includes a positioning rod, a limiting ring, a spring, a paddle, and an insert rod. The insert rod is fixed on the pressure cover and slides through the bottom shell. A positioning hole is provided on the side of the insert rod. The positioning rod slides through the bottom shell. A limiting ring is fixedly sleeved on the positioning rod. One end of the positioning rod is inserted into the positioning hole. A paddle is fixed to the other end of the positioning rod. A spring is sleeved on the positioning rod.

[0008] Preferably, a gasket is provided between the mating surfaces of the cover and the bottom shell.

[0009] Preferably, a heat exchange plate is fixed to the back of the LED backlight body, heat dissipation fins are vertically fixed to the heat exchange plate, a mounting hole is opened on the side of the bottom shell, a cooling fan is installed in the mounting hole, and a heat dissipation hole is opened at the bottom of the bottom shell.

[0010] Preferably, a second filter screen is installed inside the heat dissipation hole, and a first filter screen is installed in the air inlet of the cooling fan.

[0011] Preferably, a patch-type temperature sensor is installed on the heat exchange plate.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. In this utility model, during installation, the positioning rod is pulled by the lever, at which time the spring retracts and inserts the plug rod into the bottom shell. Then the lever is released and the positioning rod is inserted into the positioning hole on the plug rod, which can fix the pressure cover. During disassembly, the positioning rod is pulled by the lever and the plug rod is pulled out, thus enabling quick disassembly and assembly of the LED backlight body.

[0014] 2. In this utility model, the heat of the LED backlight body is transferred to the heat exchange plate. The surface-mount temperature sensor is used to measure the temperature of the heat exchange plate. When the temperature is higher than the set value, the cooling fan starts. The cooling fan can remove the heat from the heat exchange fins by blowing on them, thereby cooling the heat exchange plate and indirectly cooling the LED backlight body. Attached Figure Description

The base shell 1 and the pressure cover 5 are connected by the quick-release assembly 4, which facilitates the disassembly and assembly of the base shell 1 and the pressure cover 5. The LED backlight body 6 is fixed by the pressure cover 5. Therefore, the LED backlight body 6 is easy to disassemble and maintain.

[0020] Reference Figure 2The quick-release assembly 4 includes a positioning rod 41, a limiting ring 42, a spring 43, a paddle 44, and an insert rod 45.
