Waterproof structure of automobile controller product

The invention discloses an automobile controller product waterproof structure which comprises an outer shell and an inner shell, a circuit board is embedded between the outer shell and the inner shell, the outer shell is of a wrapped structure and is arranged on the outer side of the inner shell, the inner shell is clamped on the inner side of the outer shell to be spliced and combined, and two sets of sealing bayonets are formed in the top of the inner shell; through the wrapping type installation design of the outer shell and the inner shell and the wrapping type clamping connection system of the two sets of sealing buckles and sealing bayonets, the inner shell is promoted to be clamped in the inner layer of the outer shell in an embedded mode to be spliced and combined, then the outer shell and the inner shell are stably spliced, meanwhile, a double-layer waterproof space without splicing gaps is formed, and the waterproof effect is improved. Therefore, the circuit board is stably and safely arranged in th
