Description

A new type of automobile windshield wiper

Technical Field

The utility model belongs to the technical field of windshield wipers, in particular to a novel automobile windshield wiper.

Background Art

A windshield wiper, also known as a windshield wiper, is a tool used to simply clean the windshield of a motor vehicle to prevent rain and other dirt from affecting the line of sight. Generally, a car has two front windshield wipers, which are connected at the same time by a multi-link linkage mechanism. The wipers are driven by a drive motor to make reciprocating motion and the swing arm is used to swing to remove dirt.

However, when the existing automobile wipers swing to remove dirt, blind spots are often generated around them, and the effect of the automobile wipers is not good. This solution solves this technical problem.

The utility model aims to provide a novel automobile windshield wiper, which solves the technical problem that the existing automobile windshield wiper has a poor dirt removal effect. A guide groove is arranged at the outer edge of the automobile windshield, and a brush strip on the sliding arm is driven to move by a slider, so that the dirt at the four corners of the automobile windshield is cleaned more thoroughly, and the automobile wiper has a better effect.

A novel automobile windshield wiper comprises a swing arm swingably arranged on the outside of an automobile windshield, a slide groove being arranged on one side of the swing arm, and further comprises a slide arm slidably arranged in the slide groove on one side, a brush strip connected to the other side of the slide arm on one side, and the other side of the brush strip being in detachable contact with the automobile windshield;

A guide groove is provided at the outer edge of the automobile windshield, and a slider is provided at one end of the slide arm, and the slider is slidably arranged in the guide groove;

One end of the swing arm is connected to a driving motor, and the driving motor is fixedly arranged on a car sheet metal part at the periphery of the car windshield. The other end of the swing arm is a free end.

A pin is arranged at one end of the sliding arm, one end of the sliding block is rotatably arranged on the pin, and the other end of the sliding block is slidably arranged inside the guide groove.

A spring is arranged in the slide groove, one end of the spring is connected to the other end of the slide arm, and the other end of the spring is connected to the inner side of the swing arm.

The driving motor is located below the automobile windshield, and the length of the brush strip is slightly smaller than the minimum distance between the motor shaft of the driving motor and the guide groove.

Compared with the prior art, the beneficial effects of the utility model are:

(1) A guide groove is provided at the outer edge of the car windshield, and the brush strip on the sliding arm is driven by the slider to move, so that the dirt at the four corners of the car windshield can be cleaned more thoroughly, and the effect of the car wiper is better;

(2) The structure is simple, and the decontamination effect can be achieved through a swing arm. The swing arm does not have a complex linkage structure, and the operation is more stable and reliable;

(3) The smaller size reduces the space and material occupied by the car, saving production costs.

DETAILED DESCRIPTION

In order to more clearly illustrate the technical features of this solution, this solution is described below through specific implementation methods.

Referring to Fig. 1 to Fig. 4, a novel automobile windshield wiper comprises a swing arm 3 swingably arranged on the outer side of an automobile windshield 1, a slide groove is arranged on one side of the swing arm 3, and further comprises a slide arm 4 slidingly arranged in the slide groove on one side, a brush strip 5 connected to the other side of the slide arm 4 on one side, and the other side of the brush strip 5 is in detachable contact with the automobile windshield 1;

A guide groove 2 is provided at the outer edge of the automobile windshield 1, and a slider 7 is provided at one end of a slide arm 4, and the slider 7 is slidably disposed in the guide groove 2;

One end of the swing arm 3 is connected to a drive motor 8, which is fixedly mounted on a car sheet metal part on the periphery of the car windshield 1, and the other end of the swing arm 3 is a free end;

The swing arm 3 swings along the automobile windshield 1 at an angle of 180 degrees through the driving motor 8 .

A pin shaft 9 is disposed at one end of the slide arm 4 , one end of the slider 7 is rotatably disposed on the pin shaft 9 , and the other end of the slider 7 is slidably disposed inside the guide groove 2 .

A spring 6 is arranged in the slide groove, one end of the spring 6 is connected to the other end of the slide arm 4 , and the other end of the spring 6 is connected to the inner side of the swing arm 3 .

The driving motor 8 is located below the automobile windshield 1 , and the length of the brush strip 5 is slightly smaller than the minimum distance between the motor shaft of the driving motor 8 and the guide groove 2 .

The specific working process of this utility model:

When in use, the car wiper switch is started, and the swing arm 3 is driven to swing by the driving motor 8, and the swing arm 3 drives the sliding arm 4 to swing. Since the slider 7 at one end of the sliding arm 4 is slidably set in the sliding groove, and the car windshield 1 is often an irregular shape, when the sliding arm 4 swings, it will also slide along the sliding groove of the swing arm 3, so that the brush strip 5 connected to the swing arm 3 can always cover the edge of the car windshield 1, avoiding the occurrence of dead angles in the car windshield 1, and having a better decontamination effect on the car windshield 1. Since the wiper can rotate 1180 degrees along the car windshield, only one rain The scraper can complete the removal of dirt from the automobile windshield 1. The elastic force provided by the setting of the spring 6 can make the sliding arm 4 in the swing arm 3 more stable. The type of spring 6 can be a compression spring 6. When the swing arm 3 swings to the corner of the automobile windshield 1, the thrust of the spring 6 assists the slider 7 to push the sliding arm 4 out, and the operation of the sliding arm 4 is smoother. When the swing arm 3 swings to the top of the automobile windshield 1, the component force generated by the restraining force of the guide groove 2 on the slider 7 makes the sliding arm 4 overcome the thrust of the spring 6 and slide in the swing arm 3, thereby completing the entire rotation stroke of the swing arm 3.

Since the swing arm 3 has no complicated linkage structure, the operation is more stable and reliable; the volume is more compact, which reduces the space and material occupied by the car and saves production costs.

Technical features not described in the present invention can be achieved through or by adopting existing technologies, and will not be elaborated here. Of course, the above description is not a limitation of the present invention, and the present invention is not limited to the above examples. Changes, modifications, additions or substitutions made by ordinary technicians in this technical field within the essential scope of the present invention should also fall within the protection scope of the present invention.
