Description
Technical Field
[0001] The utility model relates to the technical field of power supply equipment, in particular to an over-temperature protection power supply. Background Art
[0002] A thermal power supply is an electronic device that has an over-temperature protection function designed to prevent damage to the device due to overheating. This type of power supply is commonly used in various electronic devices and systems, such as computers, televisions, stereos, chargers, etc. The working principle of the thermal power supply is to monitor the temperature of the device. Once the temperature exceeds the safe range, the power supply will take measures to reduce or cut off the current to prevent the device from being damaged by overheating. This can be achieved through built-in sensors that monitor temperature changes inside or outside the device.

The over-temperature protection LED driver power supply collects the temperature on the heat conduction plate through a temperature sensor, thereby analyzing the temperature of the LED driver power supply body at this time, and transmits the collected temperature to the control module through the temperature sensor to selectively control the motor, fan or control the air switch according to the temperature. When the motor rotates, it can drive the two fans to rotate outside the LED driver power supply body, thereby playing a role in heat dissipation for the LED driver power supply body. When the temperature of the LED driver power supply body is too high, the power supply circuit of the LED driver power supply body can be disconnected by controlling the air switch, thereby effectively playing a role in over-temperature protection, and further improving the service life of the LED driver power supply body.
[0004] The above patent embodiment records that "it includes a base, a protective cover and an LED driver power supply body, the protective cover is fixed to the upper end surface of the base by bolts, the LED driver power supply body is fixed at the center of the upper surface of the base and is located inside the protective cover, and the outer side of the LED driver power supply body is fixed with a heat conduction plate whose one side is fixed to the upper surface of the base by bolts." It can solve the problem that the LED driver power supply is easily affected by excessive heat. The service life of the LED driver power supply, but such a connection method makes the device prone to damage when it is subjected to external impact.

[0027] like Figure 4 As shown: the connecting assembly includes four circular rings 13, two support rods 14, and a connecting shaft 15. The inner wall of the circular ring 13 is rotatably connected to the outside of the connecting rod 12, the outside of the support rod 14 is fixedly connected to the adjacent side of two of the circular rings 13, and the outside of the connecting shaft 15 is rotatably connected to the inside of the support rod 14.
[0028] like Figure 5 As shown: a foam airbag 16 is fixedly connected to the bottom of the inner wall of the shell 1, and the material inside can cool down the device and extinguish the fire. A heat dissipation hole 17 is opened on the external front side of the shell 1 to facilitate ventilation of the device. A tying rod 18 is slidably connected to the inside of the front side of the shell 1 to cause damage to the foam airbag 16. A pressing block 19 is fixedly connected to the external front side of the tying rod 18, and a retaining ring 20 is fixedly connected to the outside of the tying rod 18. A spring 21 is sleeved on the outside of the tying rod 18, and the external rear side of the pressing block 19 contacts the external front side of the shell 1.

A support 2 is fixed at the bottom of the power supply casing 3. When the device is subjected to external impact, the support 2 will apply pressure to the multiple connecting blocks 8 at the bottom, so that the connecting rod 9 is pressed downward. In the process of the connecting rod 9 moving downward, the spring 11 will provide elastic force to the sliding block 10, so that the support rod 14 connected between the multiple sliding blocks 10 obtains elastic force to resist the impact force, thereby weakening the impact force on the device and achieving the purpose of buffering. When the device has an internal fire or other faults due to special reasons, pressing the pressing block 19 allows the piercing rod 18 to obtain impact force to impact the foam airbag 16 to cause the internal material to overflow, thereby cooling and extinguishing the power supply casing 3 through the holes at the bottom of the support 2.
