This symmetrical layout helps prevent stress concentration or tilting caused by unbalanced installation.

[0022] Furthermore, a mounting frame is provided inside the dust screen, and a cooling fan is provided on the top of the mounting frame.

This design not only greatly improves the convenience of use and eliminates the tedious manual operation, but also effectively isolates dust and pollutants when the vehicle is stopped, protects the internal control circuit and components, and thus prolongs the service life of the controller. At the same time, the dust shield mechanism cleverly balances the needs of heat dissipation and dust prevention. During driving, the cooling fan can smoothly exhaust and dissipate heat to ensure that the internal temperature of the controller is moderate. After parking, the buckle cover will promptly close the dust shield net to achieve excellent dust prevention effect.

[0030] 2. The utility model can effectively fill the gap between the buckle cover and the dust screen by providing a sealing ring, prevent dust, moisture or other pollutants from entering the inside of the controller through these gaps, thereby protecting the internal control circuits and components from pollution and damage.
