Abstract
The utility model discloses a waterproof wiper motor assembly which comprises a motor body and a reduction gearbox assembly, wherein the reduction gearbox assembly consists of a reduction gearbox body and a motor output shaft, the reduction gearbox body consists of a reduction gearbox body longitudinal part and a reduction gearbox body transverse part, a waterproof bushing and an inner sealing ring are arranged between the reduction gearbox body longitudinal part and the motor output shaft, and a waterproof cover is arranged on the reduction gearbox body longitudinal part and below the inner sealing ring. The longitudinal part of the reduction gearbox body and the transverse part of the reduction gearbox body are of an integrated structure, so that the installation procedure can be reduced, the production cost can be reduced, and the outward part of the waterproof bushing is provided with a flanging and protruding structure, so that the waterproof bushing is more beneficial to sealing and waterproofing. The utility model has the advantages of effective sealing and good waterproof performance, effectively prevents rainwater from flowing into the motor body along the reduction gearbox body, avoids the motor body from being blocked, and prolongs the service life of the wiper motor assembly.
Description
Technical Field
The utility model relates to a motor, in particular to a motor assembly mainly applied to an automobile windscreen wiper.
Background
At present, a windscreen wiper (also called a wiper) is an indispensable part of an automobile, and the windscreen wiper is used for receiving power transmitted by a windscreen wiper motor and a connecting rod mechanism and generating wiper arm pressure at the same time, and the wiper rod drives a wiper blade to wipe a windshield, so that foreign matters on the glass are cleaned. The common wiper consists of a plurality of subassemblies, including a wiper motor, a linkage mechanism (comprising an output shaft), a wiper arm assembly, a wiper rod, a wiper blade, a motor mounting plate assembly and the like, and is also provided with a wiper water spraying device and a washer thereof. Wherein, the reducing gear box subassembly of windscreen wiper motor assembly (especially back windscreen wiper motor assembly) is convenient the bush and impresses, and the chamfer structure is made to the tip of reducing gear box body, and the rainwater will be unavoidable along reducing gear box body seepage to the motor body the inside like this, because of windscreen wiper motor assembly is sealed poorly, leads to outside rainwater to leak to the motor body inside easily, leads to motor body poor contact.
Disclosure of Invention
The utility model aims to overcome the technical defects and provide the waterproof wiper motor assembly which can realize effective sealing and has good waterproof performance.
The aim of the utility model is achieved by the following technical scheme: the waterproof wiper motor assembly comprises a motor body and a reduction gearbox assembly, wherein the reduction gearbox assembly consists of a reduction gearbox body and a motor output shaft, the reduction gearbox body consists of a reduction gearbox body longitudinal part and a reduction gearbox body transverse part, a waterproof bushing and an inner sealing ring are arranged between the reduction gearbox body longitudinal part and the motor output shaft, and a waterproof cover is arranged on the reduction gearbox body longitudinal part and below the inner sealing ring.
The longitudinal part of the reduction gearbox body and the transverse part of the reduction gearbox body are of an integrated structure, a groove structure is formed in the position, matched with the waterproof bush, of the longitudinal part of the reduction gearbox body, and the outward part of the waterproof bush is provided with a flanging and protruding structure.
After the utility model is adopted, the inward inner sealing ring, the outward waterproof bushing and the waterproof cover are arranged in multiple ways, so that the utility model has the advantages of effective sealing and good waterproof performance, the problem of poor sealing of the wiper motor assembly can be solved, rainwater can be effectively prevented from flowing into the motor body along the reduction gearbox, the motor body is prevented from being blocked, and the service life of the wiper motor assembly (particularly the rear wiper motor assembly) is prolonged. The longitudinal part of the reduction gearbox body and the transverse part (i.e. the mounting plate) of the reduction gearbox body are of an integrated structure, so that the mounting procedure can be reduced, the production cost is reduced, and the outward part of the waterproof bushing is provided with a flanging and protruding structure, which is more beneficial to sealing and waterproofing.
Drawings
Fig. 1 is a schematic structural view of a waterproof wiper motor assembly according to the present utility model.
Fig. 2 is a schematic view of the waterproof bushing, the inner seal ring, and the waterproof cover in fig. 1 in a separated state.
Fig. 3 is an enlarged view of a symbol a in fig. 1.
Detailed Description
The utility model is described in detail below with reference to the drawings and the detailed description.
Referring to fig. 1 to 3, the waterproof wiper motor assembly for the automobile wiper according to the present utility model comprises a motor body 6 and a reduction gearbox assembly, wherein the reduction gearbox assembly comprises a reduction gearbox body 8 and a motor output shaft 1, the reduction gearbox body 8 comprises a reduction gearbox longitudinal portion 4 and a reduction gearbox transverse portion 7 (i.e. a mounting plate), a waterproof bushing 2 (facing outwards) and an inner sealing ring 3 (facing inwards) are arranged between the reduction gearbox longitudinal portion 4 and the motor output shaft 1, and a waterproof cover 5 is arranged on the reduction gearbox longitudinal portion 4 and below the inner sealing ring 3.
The reduction gearbox longitudinal part 4 and the reduction gearbox transverse part 7 are of an integral structure (made of plastic materials), a groove structure 9 (convenient for embedding of the protruding part of the waterproof bushing) is arranged at the matching part of the reduction gearbox longitudinal part 4 and the waterproof bushing 2, and a flanging (upper position) and a protruding (lower position) structure 10 (shown in fig. 2) are arranged at the outward part of the waterproof bushing 2, so that the waterproof bushing and the reduction gearbox longitudinal part are in interference fit, and waterproof and sealing enhancement are facilitated.
