With the improvement of global awareness of environmental protection and the transformation of energy structure, new energy vehicles have received more and more attention and popularity due to their advantages such as zero emissions, low noise, energy saving and environmental protection. Most new energy vehicles are driven by batteries. The traditional charging method of new energy vehicles is mainly based on wired charging piles. Although this method meets the charging needs to a certain extent, it also has some limitations. For example, wired charging piles require a physical connection between the vehicle and the charging equipment, which not only increases the complexity of operation, but also may reduce the charging efficiency due to problems such as poor contact. In addition, the popularity of wired charging piles is also limited by site and space restrictions, and it is difficult to meet the charging needs of all scenarios.

When the front wheel of the car 6 is in contact with the second pressure sensor 404, the driver is prompted to stop the car through the voice device 405; S3. The adjusting push rods 305 located on both sides of the foundation pit 1 push the charging seat body 302 to adjust horizontally, and the telescopic charging head 303 extends upward and contacts the top of the protective top cover 307 to charge the car 6. The charging progress of the car 6 is displayed through the progress light strip 306; S4. The telescopic charging head 303 generates heat when charging the car 6. At this time, the temperature of the coolant in the cooling cabin 5011 gradually increases, and the water cooling mechanism 501 and the air cooling mechanism 502 are driven to operate through the trigger mechanism 503. The water cooling mechanism 501 increases the flow rate of the coolant to exchange heat, and combines with the air cooling mechanism 502 to dissipate heat and cool the inside of the foundation pit 1.

[0032] Practical application cases For the car 6 whose overall top-view area is smaller than the overall area of ​​the pressure plate 2, when the driver drives the car 6 into the entrance in a direction parallel to the two sides of the pressure plate 2 or in a turning manner, the first pressure sensor 401 can be triggered and the guide light strip 402 can be turned on, so that the driver can adjust the vehicle to the position synchronized with the light-on position of the guide light strip 402. During the entry of the car 6, the side margin of the vehicle is monitored by the infrared sensing light strips 403 on both sides, and the driver is prompted to adjust the vehicle position through the voice device 405; When the front wheel of the car 6 is in contact with the second pressure sensor 404, the language device 405 notifies the driver to stop the car in time. For the car 6 whose overall area is not larger than the pressure plate 2, taking the charging receiving end 602 located in the middle of the car 6 as an example, the car 6 can be regarded as parked in the best charging area at this time, and due to the characteristics of wireless charging itself, a certain deviation between the parking position of the car 6 and the telescopic charging head 303 can be allowed; The telescopic charging head 303 rises and starts to wirelessly charge the car 6. When the temperature of the telescopic charging head 303 rises, the magnetism of the thermistor 5034 in the trigger mechanism 503 weakens, the metal sheet switch 5033 falls and starts the water cooling mechanism 501 to accelerate the flow rate of the coolant, and starts the air cooling mechanism 502 for gas exchange, thereby reducing the overall temperature inside the foundation pit 1 and the temperature of the coolant; when the temperature of the telescopic charging head 303 drops, the thermistor 5034 re-absorbs the metal sheet switch 5033, and turns off the water cooling mechanism 501 and the air cooling mechanism 502 to save energy.
