Generally speaking, an electric vehicle uses a battery as an energy source, and through components such as a controller and a motor, it converts electrical energy into mechanical energy to move, and controls the vehicle speed by changing the magnitude of the current. With the continuous progress of power electronics, energy conservation, and control technologies, the charging equipment for electric vehicles is also constantly improving. Among them, wireless charging is a relatively advanced charging method at present, and power testing of it is an important method for equipment quality inspection.

[0003] However, when the current wireless charging equipment for electric vehicles conducts power testing, it is difficult to simulate a complex working environment, resulting in the wireless charging power supply not being able to detect the best working performance;

[0004] To solve the above problems, a wireless charging power supply testing system for electric vehicles is proposed in this application. Summary of the Invention

[0009] A driving mechanism, including three exhaust pipes, the three exhaust pipes are fixedly installed at the bottom of the annular air guide box, and the exhaust pipes are communicated with the annular air guide box;

[0010] An alignment mechanism, including a driving ring, the driving ring is slidably installed on the inner side of the annular air guide box, and three ejector rods are fixedly installed at the bottom of the driving ring. The bottom end of the ejector rod is fixedly installed with an ejector block, a connecting block is fixedly installed on the exhaust pipe, and the ejector block is rotatably connected to the corresponding connecting block.

[0011] Preferably, the magnetic field testing mechanism further includes a driving seat. Two mounting seats are fixedly installed at the top of the positioning rod. The same positioning shaft is rotatably connected between the two mounting seats. A roller is fixedly installed on the positioning shaft. A circular cam groove is formed in the roller. The driving seat is movably installed on the roller, and a moving hole is formed in the driving seat. A slider is fixedly installed on the inner wall of the moving hole. The slider is slidably connected with the circular cam groove, and the driving seat is fixedly connected with the moving block.

[0012] The rotating positioning shaft drives the roller to rotate. The roller drives the driving seat to move back and forth through the sliding connection between the circular cam groove and the slider. The driving seat drives the moving block to move, and further drives the magnetic field detector to perform magnetic field testing on the induction coil back and forth.

[0013] Preferably, a crown gear is fixedly installed on the outer side of the annular installation box. One end of the positioning shaft is fixedly installed with a driven gear. The driven gear meshes with the crown gear.

[0014] The rotating annular installation box drives the positioning rod to rotate. The positioning rod drives the driven gear to rotate around the center point of the annular installation box, and through the mutual meshing of the driven gear and the crown gear, the driven gear and the positioning shaft can be driven to rotate.

[0015] Preferably, the driving mechanism further includes an annular temperature control box. One side of the supporting plate is fixedly installed with a fixing plate. Four supporting rods are fixedly installed at the top of the fixing plate. The annular temperature control box is fixedly connected with the four supporting rods. A blower is installed at the bottom of the annular temperature control box. A conduit is installed at the top of the annular temperature control box. One end of the conduit is fixedly connected with the top of the annular installation box.

[0016] The blower blows air into the annular temperature control box. The gas in the annular temperature control box is introduced into the annular installation box through the conduit. The gas in the annular installation box is discharged through the exhaust pipe and acts on the induction coil.

[0017] Preferably, two heating blocks are installed at the top of the annular temperature control box. A refrigerator is installed at the top of the fixing plate. Two connecting pipes are installed at the top of the refrigerator. The connecting pipes communicate with the annular temperature control box, and two humidifiers are installed at the top of the annular temperature control box.

[0018] Through the settings of the heating blocks and the refrigerator, it is convenient to heat or cool the gas in the annular temperature control box, and act on the induction coil through the exhaust pipe, so as to adjust and change the working environment of the induction coil. Furthermore, the magnetic field detector can perform magnetic field testing at different temperatures. At the same time, the setting of the humidifier can facilitate the adjustment of the humidity on the induction coil, and further facilitate the magnetic field testing in different humidity environments.

[0019] Preferably, the direction adjusting mechanism further includes a lead screw. A connecting rod is fixedly installed inside the driving ring. The same fixed rod is fixedly installed on one side of the two mounting seats. The lead screw is threadedly connected to the fixed rod and rotatably connected to the connecting rod.

[0020] The rotating lead screw can move up and down through the threaded connection with the fixed rod, and then drive the driving ring to move through the connecting rod.

[0022] The fact that the exhaust duct is made of shape memory alloy tube material facilitates the exhaust duct to change the angle state at will. At the same time, the exhaust duct is arranged at an angle of 45 degrees with the central straight line of the annular air guide box, so that when the exhaust duct blows air, it can push the annular air guide box to rotate automatically under the reaction force of the wind, and then make the detection position of the magnetic field detector more extensive.

[0023] Preferably, a notch is opened at the top of the annular installation box, an opening is opened at the top of the annular air guide box, the opening is communicated with the annular installation box, and the annular air guide box is rotatably connected to the notch.

A sliding block is threadedly connected to the screw rod. The sliding block is fixedly connected to the support plate. A motor is fixedly installed on one side of the base, and the output shaft of the motor is fixedly connected to the screw rod.

[0026] The output shaft of the motor drives the screw rod to rotate. The screw rod can drive the support plate to move through the threaded connection with the sliding block, and then drive the magnetic field detector to move to the induction coil for testing.

[0027] In summary, the technical effects and advantages of the present invention are as follows:

[0028] 1. Multi-dimensional environmental simulation test

[0029] Temperature and humidity adjustment: The system is provided with a heating block, a refrigerator and a humidifier, which can adjust the working environment temperature and humidity of the induction coil. This enables magnetic field testing of the induction coil under different temperature and humidity conditions, simulating various complex environments that the wireless charging power supply of electric vehicles may encounter in actual use, so as to more comprehensively and accurately evaluate its performance.

[0030] Wind direction angle adjustment: The exhaust duct is made of shape memory alloy tubing and can be freely adjusted in angle. At the same time, the vertical angle of the exhaust duct can be adjusted through the steering mechanism. This not only changes the wind direction, enabling the wind force to act precisely on the induction coil, but also allows it to move away from the induction coil, achieving flexible adjustment. This makes it possible to simulate different heat dissipation conditions and external airflow effects, contributing to a more realistic test of the performance of the induction coil in different environments.

[0031] 2. Automatic rotation and movement detection mechanism

[0032] Automatic rotation detection: The exhaust duct is set at a 45-degree angle to the center line of the annular air guide box. When blowing air, the annular air guide box is automatically rotated by the reaction force of the wind. This design enables a wider range of detection positions for the magnetic field detector, achieving multi-angle detection without the need for additional complex driving devices, improving the detection efficiency and comprehensiveness.

[0033] Movement detection: The motor drives the screw to rotate, causing the sliding block to drive the support plate to move, and then driving the magnetic field detector to move to the induction coil for testing. This movable detection method facilitates the detection of induction coils at different positions, enhancing the flexibility and adaptability of the system.

[0034] 3. Reciprocating detection structure

[0035] In the magnetic field testing mechanism, the rotating annular mounting box drives the positioning rod to rotate, and the positioning rod drives the driven gear to rotate around the center point of the annular mounting box. Through the meshing of the driven gear and the crown gear, the driven gear and the positioning shaft rotate self-driven. The positioning shaft drives the roller to rotate, and the roller drives the driving seat to move back and forth through the sliding connection of the circulating cam groove and the slider, ultimately driving the magnetic field detector to conduct magnetic field tests on the induction coil back and forth. This ingenious mechanical structure design realizes the reciprocating detection of the magnetic field detector, ensuring a comprehensive and detailed detection of the magnetic field of the induction coil.
