The method of cleaning the glass of a vehicle and device for its implementation

 

(57) Abstract:

The invention relates to electric vehicles and can be used for washing and cleaning windshields and headlight lenses. The purpose of the invention is to improve the treatment efficiency. For this purpose, in a known way to clean the glass of the vehicle by movement of the working edge of the wiper blade against the glass and supply of washer fluid between the edges of the moving working edges takes place simultaneously in mutually intersecting directions, with at least one working edge is moved along the longitudinal axis of the brush. A device for implementing this method, containing wiper blade-shaped form with working edges that are located on the contour of the base, and the cavity formed by the inner surface of the brush, provided with a screw mounted for rotation and interaction of the working edges of the auger with the surface of the glass. Thus, cleaning of glass working edges of the brush, moving in mutually intersecting directions and spiral flow of washer fluid, increases the efficiency of cleaning glass. 2 C and 4 C.p. f-crystals, 2 Il.

The invention relates the headlights.

A known method of cleaning the glass of the vehicle by moving the wiper blade with multiple working edges on the glass along the arc of a circle centered on the axis of the brush holder and supply of washer fluid under the brush between the working edges.

It is also known a device for cleaning the glass of a vehicle, containing a brush with flexible working edges associated with a drive mechanism, and a washer of glass, comprising a tank for washing fluid, a liquid pump, the supply and drain piping and filter brush is made trough-like shape with working edges that are located along its perimeter with the formation of the closed cavity between the cleaned glass and the inner surface of the brush, and the cavity is connected a feed pipe through the hole made in the upper part of the brush, with capacity for washer fluid, and in the lower part of the brush made the hole, through which the cavity is communicated to a drain pipe with a filter, the output of which is communicated with the pump inlet connected to the outlet through the outlet pipe with capacity for washer fluid.

The disadvantages of the prototype is a low cleaning efficiency STI direct, and reverse moves. In addition, the prototypes of the main component of the movement of the washer fluid is directed along the glass, parallel to its surface, which also reduces the cleaning efficiency.

The aim of the invention is to increase the efficiency of cleaning the glass.

This goal is achieved by the fact that in the known method of cleaning the glass of the vehicle by movement of the working edge of the wiper blade against the glass and supply of washer fluid between the working edges, moving the working edges operate in mutually intersecting directions, with at least one working edge is moved along the longitudinal axis of the brush.

The aim is achieved in that at least one working edge is moved along the longitudinal axis of the brush head washer fluid.

To this end, the supply washer fluid between the working edges of the flow of washing fluid are formed in a spiral along the longitudinal axis of the brush.

The aim is achieved in that known device for cleaning the glass of the vehicle containing the wiper blade is u-shaped with a cavity formed by the inner surface of the brush, and with raspolozivom through the filter, but on the other hand feed the pipeline with capacity for washer fluid, connected to the washer pump, provided with a screw mounted in the cavity of the brush rotatably and interaction of the working edges of the auger with the glass surface, and the washer pump is connected by a sign with capacity for washer fluid and output to the feed pipe.

With this purpose the inner surface of the brush is made in the form of a cylinder with axis coinciding with the longitudinal axis of the brush, working edge of the auger is made of elastic material.

In Fig. 1 schematically shows a device with longitudinal section of the brush; Fig. 2 - section a-a in Fig. 1.

Device for cleaning glass 1 contains associated with a drive mechanism (not shown) and having a cavity 2 between the inner surfaces of the elastic working edges 3 and glass 1 brush 4. In the cavity 2, is made in the form of a cylinder with axis coinciding with the longitudinal axis of the brush, is mounted for rotation and interaction with glass 1 through the slot 5 screw 6. Working edge 7 of the screw 6 is made of elastic material. Wash glass 1 has a reservoir 8 for washer fluid 9. To the vessel 8 is connected to the hydraulic input of the liquid 13 in the upper part of the brush 4 is connected to the cavity 2, which is equipped with an opening 14 in the bottom of the brushes 4 through which the outlet pipe 15 through the filter 16 is associated with the capacity of 8. Working edge 3 made integral with the brush 4 on the sides and the ends 17 and 18 of the latter, forming an isolated space of the cavity 2, closed with not adjacent to the glass sides of the inner surfaces of the edges 3.

The device operates as follows. By means of the drive mechanism, the brush 4 when activated, moves the glass 1 and its working edges 3 and the edges 7 of the screw 6 cleans the surface of the glass 1. For washing glass 1 open the valve 11 and include a liquid pump 10. Washer fluid 9 from the tank 8 through the pipe 12 through the opening 13 is supplied into the cavity 2, getting on the glass 1, and the blades of the screw 7. Under the pressure of the fluid 9 screw is tightened, its working edge 7 in contact with the glass 1 through the slot 5, moved at an angle to the longitudinal axis of the brush 4, creating intersecting the direction of movement of the edges 3 and 7. Washed by the liquid 9, passing between the blades of the screw 6 in the cavity 2, is twisted in a spiral, creating a pulsating flux incident on the glass 1. Impurities are washed and through the opening 14 dirty washer fluid 9 flows into Phi is ensenaste circulation washer fluid 9 through the cavity 2 depending for example, the degree of contamination of the glass. In this case, the valve 11 through the drive may be filed with the signal from the sensor contamination of the glass.

Thus, cleaning of glass working edges of the brush, moving in mutually intersecting directions, and mivka glass spiral flow washer fluid increases the efficiency and speed of cleaning the glass, and therefore increase safety.

FIELD: transport.

SUBSTANCE: wiper brush consists of moving rocker (6) secured to brush body (1) by moving assemblies arranged at brush ends. Axle is arranged on one side of body end while brackets are arranged in symmetry on opposite end to support rod extending via bore of the sleeve secured at rocker (6). Sprayers connected by tube (4) are arranged in said body (1). In brush motion over the glass, body (1) turns on axle and rod displaces in said sleeve to make it thrust against the bracket of rocker (6). Note here that said sprayers displace to the zone ahead of elastic scraper (13) to spray the fluid on glass whereon said brush moves.
