With the improvement of living standards and the improvement of road traffic conditions, the demand for convenient transportation has increased. At present, the price of electric vehicles is relatively low, the cost of purchase and the cost of post-maintenance are significantly lower than those of conventional vehicles, and the convenience is high. The high-efficiency rechargeable batteries of electric vehicles can save energy and reduce emissions. Due to the large amount of burning gasoline and kerosene, PM2.5 is seriously exceeded, and the air pollution is serious, which poses serious threats and damage to people's life. In the case of using electric vehicles, the charging of electric vehicles is generally charged in a wired form, however, For the living environment of people in most cities, they live in high-rise buildings. It is not practical to charge electric vehicles with wired charging. It is not only convenient to use wireless charging, but also beautiful, and reduce the use of data lines and wires. Avoid the danger of fire caused by aging of the circuit, but charging with wireless charging sometimes does not allow the charger to be accurately aligned, making charging difficult.

Therefore, the production of a simple structure, reasonable design, convenient operation, high safety factor, high degree of intelligence, automatic adjustment of the charger position, can effectively improve the accuracy of charging, energy saving and emission reduction wireless car charger position automatic calibration device , has a broad market prospects.

In view of the deficiencies of the prior art, the utility model provides a simple structure, reasonable design, convenient operation, high safety factor, high degree of intelligence, automatic adjustment of the charger position, effective improvement of charging accuracy, energy saving and emission reduction. Auto wireless charger position automatic calibration device.

The technical solution of the utility model is realized as follows: an electric vehicle wireless charger position automatic calibration device, comprising: a magnetic induction wireless charging stand, a charging wire disposed on a side of the magnetic induction wireless charging stand, and a charging connector fixedly connected with the charging wire The magnetic induction wireless charging stand is movably mounted on the ground of the electric car parking space, and the magnetic induction wireless charging stand is connected with a driving motor, and the driving motor can make the magnetic induction wireless charging seat in the X direction And the position adjustment in the Y direction, the bottom of the electric vehicle is installed with a vehicle bottom magnetic induction charger, and the vehicle bottom magnetic induction charger converts the electromagnetic field of the magnetic induction wireless charging base into an induced voltage, and the induced voltage generates an induced current to the electric vehicle battery. Charging, the bottom magnetic induction charger is connected with a current sensor, the current sensor collects the charging current, the current sensor is connected with the wireless communication module transmitter, and the wireless communication module transmitter and the current sensor are disposed between Current detection MCU enters the current information Converting, the magnetic induction wireless charging stand is connected with a wireless communication module receiver, the wireless communication receiver is connected with the driving motor, and the wireless communication module receiver and the driving motor are provided with a position calculation MCU to wirelessly charge the magnetic induction The position coordinates of the seat are converted, and the converted position movement information is sent to the drive motor, and the drive motor drives the magnetic induction wireless charging stand for position calibration.

The current detecting MCU transmits the magnitude of the charged current.

The position calculation MCU calculates and transmits the position coordinates of the magnetic induction wireless charging stand.

The driving motor drives the movement of the magnetic induction wireless charging stand to repeatedly perform the optimal charging effect.

The utility model has the following positive effects: an electric vehicle wireless charger position automatic calibration device, a magnetic induction wireless charging seat is connected with a driving motor, and the driving motor can drive the magnetic induction wireless charging seat to perform position adjustment in the X direction and the Y direction. The vehicle bottom magnetic induction charger is equipped with a current sensor. After the current detection MCU processes the current signal, it is sent out through the wireless communication module transmitter. The wireless communication module receiver of the magnetic induction wireless charging station receives the current sent by the vehicle bottom magnetic induction charger. Signal, position calculation MCU compares the current magnitude with the base position coordinate, calculates the coordinates of the new magnetic induction wireless charging stand, and adjusts the coordinates of the magnetic induction wireless charging stand in the X direction and the Y direction by the driving motor to complete the magnetic induction wireless charging seat. Position adjustment, the driving motor drives the magnetic induction wireless charging seat to repeat the movement to achieve the best charging effect. The new structure is simple, the design is reasonable, the operation is convenient, the safety factor is high, the intelligence is high, and the charger position can be automatically adjusted. Effectively improve Charging accuracy, energy saving and emission reduction.
