Description

The invention relates to the automotive industry, in particular to devices for cleaning the glass of vehicles, and can be used to prevent the wiper blade from freezing to the windshield and rear window of the car.

A device for a windshield wiper for a car is known, comprising a lever with a brush (patent SU A3, B60S 1/34, publ. 08.23.1993). The disadvantage of the wiper is that the brushes at low ambient temperatures can undergo significant icing and freeze to the glass. The freezing of the brush to the glass and its subsequent detachment lead to premature brush wear, reduced quality of cleaning the glass, overloading the electric motor of the car, which drives the lever with the brush, and ultimately shortening the life of both the wiper and the electric motor, more frequent replacement brushes, increase the time and cost of maintaining the vehicle, reduce driver reliability and driving safety. A wiper for a vehicle is also known, comprising a lever (leash) with a brush made with the possibility of brush contact with the glass being cleaned and comprising a device for heating the brush in order to prevent the brush from freezing to the glass, protect the glass cleaner motor gear from overloads when the brush is separated from the glass (patent RU 111492 U1, B60S 1/38, publ. 12/20/2011, bull. 35). The disadvantage of this wiper is that the strip of rubber brush scraper freezes to the glass being cleaned, which leads to deterioration of the brush characteristics and a decrease in the quality of glass cleaning, as well as to its more frequent replacement. To eliminate frost in the area of contact between the brush and glass, the driver must start the vehicle, turn on the device for heating the brush and, depending on the size of the frost, withstand a certain period of time. In this case, the strip rubber scraper of the brush undergoes a sharp temperature drop, which causes it to crack and shorten its service life. In addition, when the engine of the vehicle and the device for heating the brush there is an additional fuel consumption. Actions to eliminate ice accumulation lead to additional costs of time and energy on the part of the driver to prepare the vehicle for movement. All this causes driver fatigue and reduces its reliability and traffic safety.

Bending the wiper arm while the vehicle is parked away from the glass cannot be considered an acceptable solution to prevent the brush from freezing to the glass, as it creates maximum tensile forces acting on the lever springs (leash), pressing the brush to the glass being cleaned. Maximum tensile forces worsen the elastic properties of the lever spring, which makes the wiper inoperative.

The specified wiper is technically the closest to the proposed utility model and adopted as a prototype.

The utility model was tasked with improving the quality of glass cleaning, reducing energy consumption and the cost of repairs and maintenance, increasing the life of the vehicle and reducing the time it takes to prepare the vehicle for movement, to increase driver reliability and traffic safety.

The technical result of the utility model is to increase the life of the wiper and reduce the time it takes to prepare the vehicle for movement.

The technical result is achieved due to the fact that in the wiper for a vehicle, including a lever with a brush made with the possibility of brush contact with the glass being cleaned, the lever contains a device for installing the brush at the required distance from the glass to prevent brush and glass contact (hereinafter - the device) comprising a housing fixed to a lever by means of a U-shaped holder with a pivotally made stop fixed in a part of the housing facing the side of the brush or away from the brush, a stop tip nen of elastic material, wherein the device is arranged movably along the center line of the lever.

The drawing shows a wiper for a vehicle, a General view.

The wiper contains a brush 1 on the lever 2, on which a U-shaped holder 3 of the device for mounting the brush 1 is made at the required distance from the glass in the form of a body 4 with a stop 6. The stop 6 has a tip 7 made of elastic material. The holder 3, with its upper part resting on the lever 2, has side walls 8, inside which the housing 4 is located.

The wiper for the vehicle operates as follows.

During the movement of the vehicle, the stop 6 is in a fixed position inside the housing 4, which allows the wiper through the brush 1, lever 2 and an electric motor (not shown) to clean the glass. After stopping and directing the vehicle to the parking lot, there is no need to clean the windows. The emphasis 6, which is located during the movement of the vehicle inside the housing 4, is rotated around the hinge 5 towards the glass until the greatest angle of rotation is reached. The largest angle of rotation of the stop 6 around the hinge 5 will determine the maximum and necessary distance of the brush 1 from the surface of the glass being cleaned, sufficient to prevent the occurrence of ice accumulation and freezing of the brush to the glass. In conditions of negative ambient temperatures, frosting and freezing of the brush to the glass will not occur, since the brush will not have contact with the glass. The existing gap between the glass and the brush will not allow foreign objects to linger on the glass, such as leaves falling from trees, snow, household garbage. To bring the wiper to the working position before the vehicle begins to move, the stop 6 is returned to its original position by turning away from the glass until it is fixed in the housing 4.

When reusing the car, the driver will need to spend less effort and time preparing the car for movement. Keeping forces, the driver will pay more attention to compliance with traffic rules, which will increase traffic safety.

The following wiper design options are available:

1. A wiper, in which the device comprises a housing 4 fixed to a lever 2 from the side of the glass being cleaned by means of a U-shaped holder 3 with a pivotally made stop 6. The greatest angle of rotation of the stop 6 for the dimensions of the body 4 towards the glass determines the greatest distance between the brush 1 and the glass . While the brush 1 is in the working position, the stop 6 is inserted and fixed in the groove (recess) of the housing 4.

2. A wiper with a stop 6 fixed in the part of the housing 4 facing the brush 1. This design allows you to most accurately set the required distance between the brush and the glass with minimal tensile forces acting on the springs of the lever 2 (leash), pressing the brush 1 to the cleaned glass.

3. The wiper, in which the stop 6 is fixed in the part of the housing 4, facing away from the brush 1. This version of the wiper allows you to use the minimum dimensions of the stop 6, which creates the preconditions for saving material, energy and reducing the cost of the wiper.

4. A wiper in which the tip 7 of the stop 6 is made of an elastic material. The execution of the tip 7 of elastic material will reduce the risk of damage to the glass in the area of its contact with the tip 7.

5. A wiper with a device configured to move along the axial line of the lever 2. This design will allow you to change the distance between the brush 1 and the glass of the vehicle at the same rotation angles and dimensions of the stop 6.

6. The wiper contains a device made of polyethylene or propylene of frost-resistant grades. The specified wiper can be used in the widest range of negative ambient temperatures.
