Embodiment Construction

[0025] The specific implementation, features and functions of a front wiper motor proposed according to the present invention will be described in detail below in conjunction with the accompanying drawings and preferred embodiments.

[0026] Such as figure 1 Shown is a schematic diagram of the assembly of the wiper motor, including a motor housing 1 , an armature 2 , a brush holder ring 3 , a reducer housing 4 , a worm gear component 5 , an integrated block 6 , and a gland component 7 .

[0027] Viewed from the outside, the motor housing 1 and the reducer housing 4 are connected by screws, the gland part 7 and the reducer housing 4 are connected by buckles, the motor housing 1, the reducer housing 4, and the gland part 7 The three form the shape of the wiper motor. After the motor is energized, the internal armature 2 rotates at a high speed, and the teeth of the armature 2 mesh with the teeth of the worm gear part 5 to drive the worm gear part 5 to rotate, and the worm gear ...

Abstract

The invention discloses a front wiper motor. The front wiper motor comprises a motor housing (1), an armature (2), a brush holder ring (3), a decelerator housing (4), a worm gear part (5) and a gland part (7). The front wiper motor is characterized in that the brush holder ring (3) is further electrically connected with an integrated block (6), and the integrated block (6) is connected with an external plug; the brush holder ring (3) is provided with a through groove (8); the decelerator housing (4) is provided with two U-shaped grooves (9); and after the brush holder ring (3) is connected with the decelerator housing (4), the through groove (8) are aligned with the U-shaped grooves (9), the three grooves are identical in width, and the width of the grooves is larger than the diameter of a worm shaft (11) of the armature (2) by 1-3mm. The front wiper motor is redesigned in the aspects of: motor assembling convenience, motor sealing performance, gland plug sheets and blocks and the like, the manufacturing cost of the motor is lowered, and the assembling time is saved.

Description

technical field [0001] The invention relates to a wiper motor of a vehicle wiper device. The motor is used to drive a wiper mechanism, and then drive a wiper arm assembly to clean the windshield of an automobile. Background technique [0002] The external structure of the wiper motor is composed of a motor housing, a reducer housing, and a gland part. The armature drives the worm gear to rotate inside, and the worm gear shaft drives the external mechanism to reciprocate, and then drives the wiper arm assembly to wipe the glass. Clean the windshield. [0003] In terms of motor assembly, in the past wiper motors, after the brush holder ring is riveted or screwed to the reducer housing, the armature is inserted from the bottom hole of the reducer housing, and the three carbon brushes of the brush holder ring are stretched during insertion. The process requires complex auxiliary tooling, and the assembly is cumbersome. [0004] On the gland, the original plug piece is directly...
