AI Technical Summary
The sealing structure of existing automotive controllers is prone to failure due to the aging of rubber parts throughout their entire life cycle, allowing dust particles and water droplets to enter the controller's interior. There is a lack of a safe and reliable sealing structure to prevent dust and water damage.
By setting sealing grooves and sealing protrusions on the shell and cover plate, and filling them with sealant through clearance fit, a dam-like structure is formed to ensure that the sealant diffuses to fill the gaps and provides good and reliable sealing performance after curing.
It achieves reliable control of the vehicle under conditions of water wading and high dust levels, meets the high standard dustproof and waterproof requirements of IP67 and IP69, and ensures a stable working environment for the electronic components inside the controller.
