Description

Wiper motor with middle position gear

Technical Field

The present utility model relates to a wiper motor.

Background

The motor of the wiper is driven by the motor, and the rotating motion of the motor is converted into the reciprocating motion of the wiper arm through the connecting rod mechanism, so that the wiper action is realized. The wiper motor can be automatically reset to a position when the motor is stopped, and the position corresponds to a position where the wiper is driven to be stopped under the windshield at present, so that the line of sight of the windshield cannot be blocked by the wiper. However, the wiper blade is parked in a position below the windshield, which is inconvenient for cleaning the windshield, especially for large vehicles.

Disclosure of Invention

The utility model aims at: in order to overcome the defects in the prior art, the utility model provides the wiper motor with the middle gear, which is provided with the middle gear for driving the wiper to stop at the vertical central line position, so that two stop positions are realized, the wiper is stopped at the vertical central line position of the windshield, and the windshield is convenient to clean.

In order to achieve the above purpose, the present utility model provides the following technical solutions:

the utility model provides a take windscreen wiper motor of median shelves, includes motor body and reduction gear, the reduction gear includes worm gear case, worm and worm wheel subassembly, and worm wheel subassembly includes worm wheel and along with worm wheel pivoted return dish, and the return dish includes return dish injection molding and return electrode dish, is fixed with on the worm gear case with return electrode dish correspondence complex feeler lever subassembly, its characterized in that: the outer circumference side and the inner circumference side of the return electrode disc are respectively provided with a notch, and the two notches are distributed in a staggered manner along the circumferential direction, so that the return electrode disc and the feeler lever assembly are correspondingly matched to form a reset stop gear and a median stop gear, the reset stop gear corresponds to the state that the wiper motor drives the wiper to stop at the lower position of the windshield, and the median stop gear corresponds to the state that the wiper motor drives the wiper to stop at the vertical central line of the windshield.

By adopting the technical scheme, two notches are formed on the return electrode plate, so that the median stop gear is increased under corresponding wiring control, namely, the condition that the wiper motor drives the wiper to stop at the vertical median position of the windscreen is achieved, and the windscreen of a vehicle is conveniently cleaned manually.

Further, the outer circumference side and the inner circumference side of the return electrode disc are respectively provided with a fixing foot in a protruding mode along the radial direction, and the fixing feet are embedded into the injection molding piece of the return electrode disc. Under the structural design, the combination of the return electrode disc and the return disc injection molding piece is firmer and more reliable.

Further, the fixing leg is bent downwards obliquely from the fixing end to the extending end. Under this structural design, the combination reliability of return electrode dish and return dish injection molding is further improved.

The utility model is further described below with reference to the accompanying drawings.

Description of the embodiments

Referring to fig. 1-4, the wiper motor with the middle gear disclosed by the utility model comprises a motor body 1 and a speed reducer 2, wherein the speed reducer 2 comprises a worm gear box 21, a worm and a worm gear assembly, the worm gear assembly comprises a worm gear 22 and a return disc 23 rotating along with the worm gear 22, the return disc 23 comprises a return disc injection molding piece 231 and a return electrode disc 232, a contact rod assembly 24 correspondingly matched with the return electrode disc 232 is fixed on the worm gear box 21, gaps 2321 are formed on the outer circumference side and the inner circumference side of the return electrode disc 232, the two gaps 2321 are distributed in a staggered manner along the circumferential direction, the return electrode disc 232 and the contact rod assembly 24 correspondingly cooperate to form a reset stop gear and a middle stop gear, the reset stop gear corresponds to a state that the wiper motor drives the wiper to stop at a position below a windshield, and the middle stop gear corresponds to a state that the wiper motor drives the wiper to stop at a vertical center line of the windshield. As a conventional technology in the art, the return electrode disc 232 is embedded into the return disc injection molding part 231, the notch 2321 of the return electrode disc 232 is filled through the return disc injection molding part 231, the contact surface of the contact rod of the return electrode disc is flush with the end surface of the return disc injection molding part 231, and two notches are formed on the return electrode disc, so that a median stop gear is increased under corresponding wiring control, and after corresponding contacts of the contact rod assembly are connected, a corresponding working state of the wiper motor is achieved by driving the wiper, so that the wiper motor can be stopped in a reset state of stopping under the windshield through the wiper motor, and meanwhile, the wiper can be driven to be stopped in a vertical median line position state of the windshield, so that manual cleaning operation of the windshield of a vehicle is facilitated.

Further, the outer circumferential side and the inner circumferential side of the return electrode pad 232 are each radially protruded with a fixing leg 2322, and the fixing leg 2322 is embedded in the return electrode pad injection molding 231. Further, the fixing leg 2322 extends from the fixing end to the extending end in a manner of bending downwards. The combination of the return electrode disc and the return disc injection molding piece is firmer and more reliable.
