[0003] The inventors have discovered that the prior art still has the following defects:

[0004] The anti-seismic protection mechanism for LED controllers in the prior art adopts a traditional protection method and lacks all-round buffer protection, which may cause the circuit board to be easily damaged when subjected to impact or vibration, thereby reducing the stability and reliability of the device.

[0005] To this end, we propose an anti-seismic protection mechanism for an LED controller. Utility Model Content

[0006] The utility model mainly solves the technical problems existing in the above-mentioned prior art and provides an anti-seismic protection mechanism for an LED controller.

[0007] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: an anti-seismic protection mechanism for an LED controller, comprising a shell and a front panel installed on the front side of the shell, a circuit board with electronic components distributed on the surface is arranged inside the shell, the back side of the front panel is electrically connected to the circuit board through a wiring harness, the bottom of the circuit board is fixedly connected to a base plate, both ends of the base plate are wrapped with buffers made of elastic material, the sides of the two groups of buffers facing away from each other are squeezed and fixed to the two inner side surfaces of the shell, and the upper and lower end surfaces of the buffers are squeezed and fixed to the bottom and top of the inner sides of the shell.

[0008] Preferably, the upper and lower end surfaces of the two groups of buffers are fixedly connected with fixed plates made of hard material, and at least two groups of limit blocks are fixedly connected to the surface of the fixed plates away from the buffers. The inner top and bottom wall of the shell are provided with grooves for accommodating the limit blocks and clamping them inside at the positions corresponding to the limit blocks.

[0013] Beneficial Effects

[0014] The utility model provides an anti-seismic protection mechanism for an LED controller, which has the following beneficial effects:

[0015] (1) The anti-seismic protection mechanism of the LED controller is implemented by fixing the circuit board on the bottom plate, and the bottom plate and the buffer parts on both sides are arranged in a wrapped manner, so that a large space is reserved for the entire circuit board at the upper and lower ends of the shell. The connection between the bottom plate and the buffer parts enables the entire controller to achieve all-round buffering in the front, back, left, right, up and down directions when it is subjected to impact or vibration, thereby avoiding damage to the circuit board when it is subjected to vibration, greatly improving the stability of the device. The functional area of ​​the front panel is connected to the circuit board through a flat cable. This connection method ensures that even if the circuit board is displaced when subjected to vibration, it will not affect the connection with the front panel.

[0016] (2) The anti-seismic protection mechanism of the LED controller can firmly fix the two groups of buffers on both sides of the shell by setting a fixing plate and a limit block and a groove body for accommodating the limit block. When encountering vibration, the two groups of buffers will not be displaced. By setting an inner connecting groove and a connecting block, the area of ​​the buffers wrapping the two ends of the bottom plate can be increased, and the effective area of ​​the buffer can be increased, so that the buffering effect is better. In addition, by connecting the notch at the top of the inner connecting groove with the protrusion at the top of the connecting block, the bottom plate can achieve multi-layer buffering when subjected to impact force in the front and rear directions, thereby improving the stability of the equipment.

The functional area of ​​the front panel 2 is connected to the circuit board 3 through the cable 7. This connection method ensures that even if the circuit board 3 is displaced when subjected to vibration, it will not affect the connection with the front panel 2.
