Abstract
The utility model provides an automobile windscreen wiper motor with a novel reset plate deceleration worm gear. The automobile windscreen wiper motor comprises a body and a plurality of clamping feet. A reset plate is coated on the transverse plane of a worm gear via the clamping feet. The area of the reset plate is around one tenth of the area of the transverse plane of the worm gear. According to the utility model, a small reset plate worm gear is adopted and enables the original reset function of the motor to be maintained. In addition, the weight of copper material for a single part is reduced from 18 grams to 5.5 grams, so that the material is saved 70 percent. Therefore, the cost is lowered and the raw material is saved.
Description
Technical field
The utility model relates to a kind of wiper motor, relates to a kind of wiper motor with novel resetting plate deceleration worm gear especially.
Background technology
The function of wiper is to drive two by transmission mechanism to scrape the dirt that lever arm and windshield wiper blade scrape off on the windshield dirty before the automobile, behind the wiper several times, stirs reset switch, and positive source is received on the reset position.As internal reset short circuit not, promptly not on reset position, then electric current to the low speed end, makes motor continue to turn to reset position by the diode in the car body controller, does not cause scraping arm and windshield wiper blade to be parked in the optional position of windshield.As when forwarding reset position to, promptly anodal low speed termination ground short circuit, i.e. so-called " generator brake effect ", motor shuts down, and makes scraping arm and windshield wiper blade get back to original stand.This is the General Principle of the automatic reset system of vehicle wiper.
As Figure 1-3, prior motor is finished the running of motor by 1 combination of motor cover plate sub-unit 3 and worm gear sub-unit and function such as reset.According to the reset motor operation principle, two reseting leaf 3-1 and 3-2 are installed on the motor cover plate sub-unit 3, be arranged in parallel on the same ray in worm gear axle center, contact with worm gear metal restoring board 1-2 diverse location, to reach the purpose of control reset motor.Existing restoring board dimensional structure is bigger, because therefore restoring board copper material normally wastes a large amount of copper materials, cost is higher.
Summary of the invention
The purpose of this utility model is to reduce the size of restoring board, thereby reduces cost.
A kind of wiper motor deceleration of the utility model worm gear restoring board comprises: a body and a plurality of card base, and restoring board pastes at the worm gear end face by described card base; The size of restoring board area is 1/10 of a worm gear face area.
Wherein, described body is synthetic by the covering of the fan shapes stack of two difference sizes, and described a plurality of card bases are along edge, the different directions edge direction vertical with body plane of described covering of the fan, and extension is fixed in the hole of worm gear end face.
The little restoring board worm gear that the utility model proposes had both kept the original reset function of motor, and the single part copper material from 18 the gram reduce to 5.5 the gram, material economy 70%.Reach and reduce cost the purpose that saves material.Making and assembly process process all increase simultaneously, and properties of product satisfy various experimental conditions, have passed through the verification experimental verification of car load and single motor, are applied on a plurality of vehicles.

Can describe in detail and appended graphic being further understood by following utility model about advantage of the present utility model and spirit.
Fig. 1 is existing motor worm gear sub-unit structural representation;
Fig. 2 is existing motor worm gear restoring board structural representation;
Fig. 3 is existing motor cover plate sub-unit structural representation;
Fig. 4 is the utility model motor worm gear sub-unit structural representation;
Fig. 5 is the utility model motor worm gear restoring board structural representation.
Embodiment
Describe specific embodiment of the utility model in detail below in conjunction with accompanying drawing.
Shown in Figure 4 and 5, wiper motor deceleration worm gear restoring board of the present utility model comprises a body 2-2 and a plurality of card base 2-3, and restoring board pastes at worm gear 2 end faces by a plurality of card base 2-3.Body 2-2 is synthetic by the covering of the fan shapes stack of two difference sizes, and a plurality of card base 2-3 are along the edge, different directions edge and the vertical direction in body 2-2 plane of two covering of the fans, and extension is fixed in the hole of worm gear end face.The size of restoring board area is about 1/10 of a worm gear face area.Restoring board by with motor cover plate sub-unit 3 on two reseting leaf 3-1 contact with 3-2, with reach control reset motor purpose.
Described in this specification is preferred embodiment of the present utility model, and above embodiment is only in order to the explanation the technical solution of the utility model but not to restriction of the present utility model.All those skilled in the art comply with design of the present utility model by the available technical scheme of logical analysis, reasoning, or a limited experiment, all should be within scope of the present utility model.
Claims (2)
1. wiper motor deceleration worm gear restoring board is characterised in that to comprise: a body and a plurality of card base, and restoring board pastes at the worm gear end face by described card base; The size of restoring board area is 1/10 of a worm gear face area.
2. restoring board as claimed in claim 1, it is characterized in that described body is synthetic by the covering of the fan shape stack of two different sizes, described a plurality of card base is along edge, the different directions edge direction vertical with body plane of described covering of the fan, and extension is fixed in the hole of worm gear end face.
