AI Technical Summary
Existing in-vehicle wireless chargers have problems such as taking up space under the vehicle, poor heat dissipation, and water ingress leading to safety hazards, especially posing a threat to small animals in cold environments.
Design a waterproof vehicle wireless charger housing structure. Tempered glass, silicone cushioning pads and polyurethane waterproof adhesive are used to improve the sealing performance. A temperature sensor and PLC controller are combined to achieve intelligent heat dissipation. The outer shell is equipped with air inlet and air outlet and waterproof and breathable membrane. The inner shell uses thermally conductive silicone and heat dissipation fins to accelerate heat dissipation.
It effectively prevents moisture infiltration, ensures circuit safety, enables intelligent heat dissipation of the wireless charger, improves charging safety and reliability, and saves space under the vehicle.
