Description

A multifunctional wiper drive arm of a new energy vehicle

technical field

The invention relates to the technical field of auto parts, in particular to a multifunctional wiper drive arm of a new energy vehicle.

Background technique

New energy vehicles are a project advocated around the world, which can greatly improve the global environment. The wiper drive arm is an indispensable part of the new energy vehicle. Both ends are connected to the wiper and the drive motor. The wiper is used to clean the windshield of the car, and the wiper drive arm acts as an intermediate component to drive.

The cleaning of the windshield of the car is usually carried out by the combination of cleaning water and the wiper. At this time, not only the windshield is cleaned, but also the wiper is cleaned, but there is no self-contained wiper drive arm that is also exposed on the surface of the car. The cleaning structure, at present, can only be cleaned manually, which is troublesome.

SUMMARY OF THE INVENTION

Aiming at the deficiencies in the prior art, the present invention provides a multifunctional wiper drive arm for a new energy vehicle, which controls the electromagnet to energize or de-energize the electromagnet through a button switch, absorbs or releases the iron ball, and after the iron ball is released, Through the principle of gravity and lever, the cleaning block is pushed up to automatically clean the wiper drive arm, which is convenient for cleaning and has a good cleaning effect.

In order to solve the above technical problems, the present invention is solved by the following technical solutions: a multifunctional wiper drive arm of a new energy vehicle, comprising a wiper arm body, and a self-cleaning structure is provided on the wiper arm body, and the self-cleaning structure Including bracket body, positioning assembly, driving assembly and cleaning assembly;

The bracket body includes a support plate disposed on the wiper arm body, a support rod disposed on the support plate, and a connecting column disposed on the support rod, and a cavity is formed in the connecting column to form a hollow space. The hollow body communicates with the outside air through a through hole opened on the bottom surface of the connecting column, a connecting block is provided on the side wall of the connecting column, and a connecting block is opened on the connecting block. The groove body communicated with the cavity;

The positioning assembly includes a button switch arranged on the wiper arm body and an electromagnet arranged on the inner wall of the tank, and the button switch is electrically connected with the electromagnet;

The drive assembly includes a spring arranged on the top surface of the cavity body, an iron ball connected with the spring, a fulcrum arranged on the support plate, and a lever matched with the fulcrum, one end of the lever is the end is directly below the spring;

The cleaning assembly includes a cleaning block slidably connected to the wiper arm body, bristles disposed on the cleaning block, and a semicircle disposed on the cleaning block and abutting against the other end of the lever shaped rubber block.

The beneficial effects of the present invention are: the present invention controls the electromagnet to energize or de-energize the electromagnet through a button switch, and absorbs or releases the iron ball. After the iron ball is released, the cleaning block is pushed up by the principle of gravity and lever, and the cleaning wiper is driven automatically. Arm, easy to clean and good cleaning effect.

Figure 1 is a schematic diagram of the present invention.

Detailed ways

The present invention is described in further detail below in conjunction with the accompanying drawings and specific embodiments: Referring to FIG. 1, a multifunctional wiper drive arm of a new energy vehicle includes a wiper arm body 1, and the wiper arm body 1 is provided with a self-cleaning structure, The self-cleaning structure includes a bracket body, a positioning assembly, a driving assembly and a cleaning assembly.

The bracket body includes a support plate 21 arranged on the wiper arm body 1 , a support rod 22 arranged on the support plate 21 , and a connecting column 23 arranged on the support rod 22 . The connecting column 23 A cavity is formed inside to form a cavity body 231 , and the cavity body 231 communicates with the outside air through a through hole opened on the bottom surface of the connecting column 23 , and a connecting block 24 is provided on the side wall of the connecting column 23 . , the connecting block 24 is provided with a groove body 241 communicating with the cavity body 231 .

The positioning assembly includes a push button switch 31 disposed on the wiper arm body 1 and an electromagnet 32 disposed on the inner wall of the groove body 241 . The push button switch 31 is electrically connected to the electromagnet 32 .

The drive assembly includes a spring 41 arranged on the top surface of the cavity body 231 , an iron ball 42 connected to the spring 41 , a fulcrum 43 arranged on the support plate 21 , and a fitting connection with the fulcrum 43 . The lever 44 , one end of the lever 44 is located just below the spring 41 .

The cleaning assembly includes a cleaning block 51 slidably connected to the wiper arm body 1 , bristles 52 provided on the cleaning block 51 , and the cleaning block 51 and the other end of the lever 44 . Match with the semi-circular rubber block 53 that is pressed against it.

When the wiper drive arm does not start, the button switch is pressed against the outer surface of the car, that is, the button switch is pressed to turn on, the electromagnet is energized, and the iron ball is attracted; after the wiper drive arm is started, the button switch is separated from the outer surface of the car, That is, the button switch is turned off, the electromagnet is powered off, and at the same time, after the wiper drive arm swings up, the iron ball falls under the influence of gravity and falls into one end of the lever. The block exerts force to urge the cleaning block to slide along the wiper drive arm. During the sliding process, the wiper drive arm is automatically cleaned, and then automatically falls back to its original position under the influence of gravity.

The above embodiments are only used to illustrate the technical solutions of the present invention, but not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: The recorded technical solutions are modified, or some technical features thereof are equivalently replaced; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
