Abstract
This utility model discloses an ECU housing snap-fit structure with a boss support surface, relating to the field of electrical technology. The ECU housing snap-fit structure includes a lower housing and an upper housing. A limiting component is provided on the lower housing, comprising a boss support block and a PCBA board body. By pulling the upper housing upward through the limiting component, the U-shaped snap-fit separates from the locking block, allowing the upper housing to be removed. Then, two second fixing bolts are unscrewed to release the fixed connection between the PCBA board body and the boss support block. Next, four first fixing bolts are unscrewed to release the fixed connection between the boss support block and the lower housing. Finally, the PCBA board body is removed along the direction of the protrusion and positioning rod of the boss support block, and the boss support block is slid out of the conical block groove in the lower housing. This allows for the corresponding repair or replacement operations on the PCBA board body and the boss support block, effectively improving the practicality and flexibility of the equipment.
