AI Technical Summary
If the motor that comes with a vehicle encounters a low-lying section when it rains, the water potential of the motor needs to be closed and waterproof, but general closed and waterproofing will lead to low heat dissipation efficiency of the motor, which is prone to overheating and overloading, and reduces service life.
A waterproof and sealed motor structure is designed. By adding rotating components, including heat dissipation holes, heat dissipation boxes, micromotors, gears and fan blades, the micromotors drive the rotation of the gears and rotating rods, control the rotation of the fan blades, and form a heat dissipation channel to ensure that the motor can still effectively dissipate heat in a closed state.
Under normal circumstances, this structure can improve the heat dissipation efficiency of the motor and extend the service life; when necessary, it can be stably closed and protected, improving waterproofness, and is suitable for different environmental conditions.
