Problems solved by technology
[0003] In practical application, it is found that when the existing power drive with fast cut-off function is in use, external dust easily enters the inside of the power drive shell through the heat dissipation hole, which affects the internal structural components of the drive power, resulting in slow heat dissipation and local heating of the device. It is fragile and not easy to clean. If no cooling holes are provided, it will affect the heat dissipation of the power drive, thereby reducing the use effect of the existing power drive

The invention discloses a power drive with a quick cut-off function, which comprises a shell and a power supply body, the power supply body is arranged in the shell, a circuit board is arranged in the power supply body, a fuse is arranged on the circuit board, and a fan is arranged in the shell. According to the driving power supply, the heat dissipation closing mechanism is arranged on the shell of the driving power supply body, so that the driving power supply can automatically open the heat dissipation closing mechanism to help the driving power supply body to dissipate heat when the operating temperature of the power supply body is too high, and when the heat dissipation closing mechanism is opened, the servo motor is started to drive the connecting rod to rotate, and the connecting rod drives the gear to rotate; the gear drives an annular plate to rotate in an annular groove in a semi-ring, the interior of a clamping groove in the annular plate is clamped with a fixing column, the annular plate rotates to drive a rotating block to rotate, the rotating block is unscrewed in a matched mode, heat dissipation holes are opened for heat dissipation, and then the using effect of an existing power source drive with the rapid cut-off function is improved.
Description
technical field [0001] The invention relates to the technical field of power drive, in particular to a power drive with a quick cut-off function. Background technique [0002] LED drive power supply is a power converter that converts the power supply into a specific voltage and current to drive LED lighting. Usually, the input of LED drive power supply includes high-voltage power frequency AC (ie mains), low-voltage DC, high-voltage DC, low-voltage high-voltage Frequency AC (such as the output of an electronic transformer), etc., the existing power driver is usually equipped with a quick cut-off function to avoid some safety problems, protect users, and avoid some risks. [0003] In practical application, it is found that the existing power driver with quick cut-off function is easy to enter the inside of the power driver shell through the heat dissipation hole when in use, which will affect the internal structural components of the driver power supply, resulting in too slow...
