Abstract

The utility model relates to a windshield wiper with automatic adjustment, comprising a windshield wipe arm and a windshield wipe sheet connected with the windshield wipe arm, wherein the windshield wipe arm and the windshield wipe sheet element are connected via a clamp spring, the clamp spring comprises left and right clamp plates, provided with a groove which bottom is some bent to the two clamp plates and protruded at center, the left and right clamp plates are some bent to the inner side of the two sides, centered as the axle center of the groove. The utility model has simple structure, high reliability, non deformation, better wipe effect and non noise.

Description

Wiper with automatically regulating function

Technical field

The utility model relates to a kind of automotive fittings, especially relates to a kind of wiper with automatically regulating function.

Background technology

In order to improve the safety of automobile, all have windscreen wiper system on the general automobile, even the vehicle that has also has front and back two cover windscreen wiper systems.At present, the windscreen wiper arm of wiper both domestic and external system all is close-fitting between windscreen wiper chip module and the jump ring, can only be on the vertical direction of windscreen wiper chip module path of motion, within certain scope, freely rotate, can not swing in the same direction of windscreen wiper chip module path of motion.Such structure tends to cause a lot of problems: under normal circumstances, the windscreen wiper chip module of wiper and the surface of front windshield glass are for plumbness, and in this case, the windscreen wiper chip module is in best mode of operation, and that scrapes is clean, does not also have abnormal sound to occur; But owing to factors such as vehicle body or reason of wiper own and assemblings, tend to cause the surperficial out of plumb of wiper clearing edges and front windshield glass, this state wiper abnormal sound will occur in work, scrape sordid phenomenon, and because clearing edges and front windshield glass surface out of plumb, accumulate over a long period, cause scraping blade distortion easily, finally make the wiper disabler.

A kind of patent No. be ZL02147854.6's " screen wiper ", comprise windscreen wiper, drive reciprocating windscreen wiper electrical motor of windscreen wiper and transmission device, be provided with rain sensor, rainfall signal detection and modulate circuit, micro controller system and control interface circuit thereof, with windscreen wiper electric electromechanics bonded assembly rain shaving electrical machine alignment circuit, the input of the mouth of rain sensor and rainfall signal detection and modulate circuit links, after rainfall signal detection and modulate circuit are handled the output signal of rain sensor, the output corresponding signal is to micro controller system, and micro controller system output control signal is by the work of control interface circuit control rain shaving electrical machine alignment circuit.Under the situation of work, rain sensor, real-time identification also detects the size of rainfall (snowflake, sleet), automatically operates in optimum speed (shelves) state by micro controller system instruction wiper electrical motor.Though such structure can effectivelyly be scraped clean front windshield glass to a certain extent, structure is too complicated, damages easily.

Summary of the invention

The utility model is at occurring abnormal sound easily in the existing in prior technology work, scrape unclean, easy deformation, complex structure, technical matterss such as easy damage provide a kind of simple in structure, not fragile, distortion, the clean wiper of scraping with automatically regulating function that can not occur abnormal sound again.

Method problem of the present utility model is mainly solved by following technical proposals: comprise the windscreen wiper chip module that the windscreen wiper arm is connected with the windscreen wiper arm, described windscreen wiper arm and windscreen wiper chip module link together by jump ring, fluted on this jump ring, the bottom of described groove is slightly crooked to both sides, intermediate projections.

Above-mentioned a lot of problems occurring, substantially all is by many times not being in plumbness with glass with the windscreen wiper chip module, adjusting and this state is very difficult at ordinary times.Now that the bottom of groove is slightly crooked to both sides, intermediate projections forms a curved surface, and the degree of crook of this curved surface can be made suitable adjusting and change.The existence of this curved surface can suitable adjustment occur making automatically under the off plumb situation at windscreen wiper chip module and glass, guarantees the plumbness of windscreen wiper chip module and glass.Under vertical situation, make wiper working properly, that scrapes totally abnormal sound can not occur again, also can not be out of shape, and the structure amplitude of this structural modification current trend is little, simple in structure, not fragile.

As preferably, described jump ring includes left side clamp and right side clamp, and described left and right side clamp is the center with the axle center of groove, and is inboard slightly bent to both sides.

The left and right side clamp is the center with the axle center of groove, and is inboard slightly bent to both sides, can better adjust the upright position of windscreen wiper chip module and glass.The left and right side clamp the degree of bending be consistent in shape substantially.

As preferably, described groove is cylindric through hole, and the bottom of this groove is to the both sides bending of left and right side clamp direction, intermediate projections.

The bottom of groove just can be formed the curved surface of regulating windscreen wiper chip module and glass position to the both sides bending of left and right side clamp direction.The degree of crook of curved surface can be determined on a case-by-case basis.

Therefore, the utility model is by being the center with the left and right side clamp with the axle center of groove, inboard slightly bent and to both sides with the both sides bending of the bottom of groove to left and right side clamp direction, intermediate projections, make the utlity model has simple in structure, not fragile, distortion, the clean advantage that can not occur abnormal sound again of scraping.

The specific embodiment

Below by embodiment, and in conjunction with the accompanying drawings, the technical solution of the utility model is described in further detail.

Embodiment 1: as shown in Figure 1, the utility model comprises the windscreen wiper chip module 2 that windscreen wiper arm 1 is connected with windscreen wiper arm 1, and described windscreen wiper chip module 2 is connected with windscreen wiper arm 1 by a jump ring 3.

As Fig. 2, shown in Figure 3, described jump ring 3 comprises left side clamp 32 and right side clamp 33, has a groove 31 at the midway location place of jump ring 1.One end opening of this groove 31, opening are inner small and outside big " eight " font, are easy to be equipped with, and just the bottom is to the both sides bending of left and

right side clamp

32,33 directions for the other end, and intermediate projections constitutes a curved surface.Described left and right side clamp is the center with the axle center of groove simultaneously, and is inboard slightly bent to both sides.

In work, under windscreen wiper chip module 2 and glass off plumb situation, the curve inwardly curved surface that forms of curved surface that can be by groove 31 bottoms and left and

right side clamp

32,33 is in time adjusted the position of windscreen wiper chip module 2 and glass, makes windscreen wiper chip module 2 and glass be on the vertical position.
