[0002] Electric vehicles are electric-driven vehicles, also known as electric-drive vehicles. Electric vehicles are divided into AC electric vehicles and DC electric vehicles. Electric vehicles usually use batteries as energy sources, and convert electrical energy into mechanical energy movement through controllers, motors and other components to control the current size to change the speed of the vehicle. When electric vehicles are manufactured, they need to use road brackets. When the brackets are used, the frame needs to be sprayed and colored, so a spraying device for electric vehicle frame production is needed.

[0003] There are currently a variety of devices for spraying paint on electric vehicle frames, but the paint storage barrels of most spraying devices lack a stirring mechanism, which makes the paint easy to solidify, affecting the efficiency of spraying.
