Description

Technical Field

[0001] This invention relates to the field of wireless charging technology, and more particularly to a protective shell for a wireless charging buried transmitter. Background Technology

[0002] With the popularization of wireless charging technology, its application scenarios have gradually expanded from traditional indoor desktop scenarios to outdoor public areas (such as wireless charging of electric vehicles in parking lots, charging of shared equipment in scenic spots, and emergency charging of smart wearable devices outdoors). Among them, buried wireless charging transmitters have become one of the core components of outdoor wireless charging systems due to their advantages such as not occupying ground space, concealed installation, and automatic alignment and charging for vehicles / equipment.

[0003] The internal components of a wireless charging transmitter, such as the circuit board and coil assembly, need to be kept in a stable position within the protective casing to ensure charging efficiency (e.g., coil alignment accuracy) and impact resistance (e.g., external forces from vehicles running over them or pedestrians stepping on them). Existing protective casings often only have simple support pillars or slots inside, making them extremely easy to damage during daily use.

[0004] Secondly, when the wireless charging transmitter is working, the power components (such as the inverter and controller) and coils on the circuit board generate a lot of heat. Due to the poor air circulation in the underground environment and the fact that most existing protective shells adopt a sealed design, the lower shell body is in direct contact with the soil, making it difficult for the heat to be dissipated quickly.

[0005] Therefore, it is necessary to develop a protective shell for a wireless charging underground transmitter to solve the above problems. Utility Model Content
