[0002] With the development of new energy vehicles, battery swapping technology has also been greatly developed. Battery swapping (also known as battery replacement) refers to the way in which an electric vehicle removes the depleted power battery of the vehicle through a battery swapping device and replaces it with another set of fully charged power batteries to replenish energy on the electric vehicle. A battery swapping station is a place where the power battery of an electric vehicle is replaced. It has functions such as charging, power management, communication, and monitoring. Since it is necessary to ensure the accurate execution of the battery replacement operation during the battery swapping process, it is usually necessary to make several requirements for the parking position of the vehicle to be replaced.

Each detection device 31 includes a detection motor, a rack 311, a gear 312, a detection connecting plate 313, and a flat plate 314. The flat plate 314 is arranged at the top of the rack 311, the rack 311 is meshed with the gear 312, and the gear 312 is connected to the detection motor. The entire detection device 31 is connected to the third horizontal platform 32 through the detection connecting plate 313. An opening 321 is provided on the side of the third horizontal platform 32 away from the third vertical platform 33. The rack 311 can pass through the opening 321. When the detection motor is started, it can drive the gear 312 to rotate. The rotation of the gear 312 can drive the rack 311 to move. The rack 311 can pass through the opening 321 during the movement. After the current positioning platform 20 and the rear positioning platform 40 have reached the specified height, the detection motor is started to raise the rack 311 to the set height, and then the second lifting device 50b connected to the middle positioning platform 30 is started to lift the third horizontal platform 32 to the same height as the first horizontal platform 24 and the second horizontal platform 43. In the process of reaching the same height, since the height of the rack 311 is higher than the third horizontal platform 32, the flat plate 314 on the top of the rack 311 will first contact the bottom of the vehicle. The pressure generated by the bottom of the vehicle will cause the rack 311 to move downward, thereby driving the detection motor to rotate. The height of the rack 311 can be calculated by detecting the rotation angle of the motor. If the lowering heights are inconsistent, it means that the lifting heights of the four wheels are also inconsistent. The lifting heights of the four wheels can be adjusted by the second lifting device 50b to make the wheel heights uniform.

[0061] Through the above description, it can be known that the automobile positioning assembly provided by the utility model can realize the lifting work of the wheels independently controlled by setting the lifting device 50 on both sides of the front positioning platform 20 and the rear positioning platform 40; by setting the front centering device 22 and the rear centering device 42 on the front positioning platform 20 and the rear positioning platform 40 respectively, it can realize the angle adjustment work of the wheels independently controlled to improve the positioning accuracy; by setting the front moving device 23 on the front positioning platform 20, it can be compatible with the requirements of the wheelbase length of light trucks and passenger cars to adapt to vehicles with different body lengths; through the setting of the middle positioning platform 30 and the detection device 31, it can detect the Z-direction posture (height direction) of the body in real time, and feedback, and adjust the overall height of the body in time; through the setting of the front support device 21 and the rear support device 41, the anti-skid function of the front and rear wheels can be realized. In short, the positioning platform provided by the utility model can independently control the lifting work and angle adjustment of the front and rear wheels when the vehicle is changing the battery, and can detect the body posture in real time, making the vehicle battery changing process more convenient, fast and accurate.
