Matching structure of brushless wiper motor end cover and reducer shell

Abstract

The invention discloses a matching structure of an end cover and a reduction shell of a brushless wiper motor, which comprises the end cover (1) and the reduction shell (2), and is characterized in that the end cover (1) is provided with an end cover gluing groove (101), a limiting table (102) and at least three buckles (103); the shell (2) is provided with a boss (202) corresponding to the buckle (103); the three buckles (103) are uniformly distributed on the circumference; the end cover is a plastic part, and the plane of the end cover is marked by laser. The end cover is made of plastic, has elasticity, and is fastened with the shell through a bayonet structure, so that screws and related procedures are saved; the gluing groove is arranged in the end cover, and the end cover is assembled after being coated with sealant before assembly, so that better waterproof sealing performance can be realized, and the quality of the motor is improved.

Description

technical field [0001] The invention relates to a matching structure of an end cover and a reduction housing in a brushless wiper motor, which is applicable to all brushless motors with similar structures. Background technique [0002] The structure of the existing brushless wiper motor end cover is generally formed by bending metal parts, and is fastened with the reducer housing by screws. The use of metal end caps in this structure will increase the cost of the end caps, and fastening with screws will increase the number of parts and processes and increase the assembly time; and there is no elasticity when the metal end caps are in contact with the reducing shell, and glue coating here will cause sealing The glue overflows, forming a gap, the sealing effect is poor, and the motor is easy to enter water, which affects the function. [0003] Such as figure 1 , 2 Shown is the structure of the end cover of the existing brushless wiper motor, including the end cover 1, the r...

AI Technical Summary

Problems solved by technology

In this process, because the end cover 1 is a metal part, it is inelastic after contacting the reducer housing 2, and the sealant will be squeezed, causing the sealant to overflow in an orderly manner, forming a gap, and the sealing performance will deteriorate, and the motor may have a hidden danger of water ingress.

Because the end cover 1 needs to be fastened by screws 3, the positioning requirements are high, resulting in difficult assembly, long time consumption, and low production efficiency
