A retractable rod 9 is fixedly installed at the bottom of the movable block 4. An air guide groove 22 is provided between the charging area 3 and the movable block 4. An exhaust ring 11 is fixedly installed on the inner side of the air guide groove 22. A fan blade 24 is provided at the bottom of the air guide groove 22. A driven gear 26 is fixedly connected to the bottom of the fan blade 24. A driving gear 25 is provided in the charger body 1. A motor is provided at the output end of the driving gear 25. A plurality of exhaust ports 23 are provided on the exhaust ring 11.

[0034] When the temperature of the mobile phone is too high and needs to be cooled, by pressing the button 10, the retracting rod 9 receives the instruction, so that the movable block 4 moves inward and retracts into the charger body 1, and then the motor and the fan blades 24 cooperate with each other to make the fan blades 24 rotate rapidly in the charger body 1, thereby generating wind energy, and the exhaust ring 11 and the exhaust port 23 cooperate with each other to facilitate the rapid cooling of the mobile phone. The movable block 4 and the exhaust ring 11 are both located in the middle of the charging area 3, so that the charging effect will not be affected when the mobile phone is cooled. This structure can solve the problem that the wireless charger in the prior art needs to completely fit the mobile phone on the car charger when charging the mobile phone, which causes the heat of the mobile phone to not volatilize well. In the traditional car wireless charger, the surface temperature of the electronic device is prone to overheating during the charging process. When the device temperature is overheated, the surface temperature of the electronic device can only be reduced by reducing the charging power, which reduces the technical problem of reduced charging efficiency, thereby improving the practicality of the entire car wireless charger.

[0035] Furthermore, by the mutual cooperation between the fixed block 12 and the clamping block 5, the clamping block 5 can be fixed on the charger body 1 to achieve the effect of auxiliary clamping of the mobile phone. Secondly, by the mutual cooperation between the connecting block 17 and the spring 18, the position of the clamping block 5 can be flexibly adjusted to achieve the effect of clamping the mobile phone, and the rubber pad 6 arranged on the inner side of the clamping block 5 can prevent the clamping block 5 from causing damage to the mobile phone, and by the mutual cooperation between the clamping block 13 and the slide groove 19, the clamping block 5 can be kept stable and flexible to slide in the fixed block 12.

The provided protective shell 20 can not only support and protect the motor, but also achieve the effect of silencing and shock absorption. At the same time, the provided USB interface 7 can assist in charging electronic devices that cannot be wirelessly charged. Secondly, the entire charger body 1 can be charged through the charging port 8. Finally, the installation groove 21 is provided to facilitate the installation of electronic components used in conjunction with the charging area 3. The groove 27 can make the movable block 4 not blocked by the fan blades 24 when it is retracted into the charger body 1, so that the movable block 4 has a certain activity space. Secondly, the groove can avoid mutual influence with the retracting rod 9.
