[0002] New energy vehicles refer to vehicles powered by non-traditional fuels. The main types include pure electric vehicles, plug-in hybrid vehicles and fuel cell vehicles. Pure electric vehicles rely on battery energy storage to drive electric motors and have no tailpipe emissions. Plug-in hybrid vehicles can switch to traditional fuel drive after the battery is exhausted. Fuel cell vehicles use the reaction of hydrogen and oxygen to generate electricity. New energy vehicles have promoted the automotive industry's transition to sustainable energy, reduced dependence on traditional oil resources, and helped reduce environmental pollution and the impact of global climate change.

[0003] Automotive bearings are key components that support the rotation of various vehicle parts. They are usually composed of inner rings, outer rings, rolling elements and cages. They reduce friction and wear between components such as tires, transmission systems and engines, and improve mechanical efficiency and operating smoothness. Common bearing types include ball bearings, roller bearings and angular contact bearings. Various types play an important role in the automotive industry based on their design and application scenarios. High-quality bearings can reduce energy consumption, extend the service life of automotive parts, and improve vehicle safety and reliability.

[0004] Bearings directly affect the running smoothness and efficiency of vehicles. Testing can ensure their performance stability under high-speed, high-temperature and high-load environments. Therefore, bearings need to be randomly inspected and tested before leaving the factory. However, traditional testing methods are complicated and inefficient. Therefore, a new energy vehicle bearing detection device is proposed to solve the above problems. Utility Model Content

The spring 4 is used to push the push plate 5 to reset the clamping block 8, and the spring 4 is used to drive the clamping rod 7 to work. The push rod 6 is for the convenience of the operator to manually press the push plate 5 to drive the clamping rod 7 to work. The clamping rod 7 is used to control the opening and closing of the clamping block 8. A groove is provided on the right side to allow the push plate 5 to slide inside to achieve opening and closing. The clamping block 8 is made of rubber for anti-slip, and its surface has grooves of different depths to match bearings of different sizes. The slide groove 9 is used to limit the movement direction of the slider 13.

[0032] Reference Figure 1 - Figure 3 The speed detection component includes an electric push rod 10 and a slider 13. The left end of the electric push rod 10 is rotatably connected to the inner wall of the shell 1, and the output end of the electric push rod 10 is rotatably connected to the rotating plate 11.
