Description

A high-efficiency all-round wiper

technical field

The present invention relates to a wiper, in particular to a high-efficiency omnidirectional wiper.

Background technique

The scientific name of the wiper (Windshield Wiper) refers to the piece structure installed in front of the windshield, which is composed of a motor, a reducer, a four-bar linkage, a wiper arm spindle, and a wiper blade assembly. It is to sweep away the rain, snow and dust on the windshield that obstruct the view. The wiper is a device used to wipe off the raindrops and dust attached to the windshield of the vehicle to improve the visibility of the driver and increase driving safety. Cars almost everywhere have windshield wipers because they are required by law. Vehicles such as hatchbacks and recreational vehicles also have wipers on the rear windows. In addition to cars, other means of transportation are also equipped with wipers, such as trains and trams. Some engineering tools, such as cranes, are also equipped with wipers.

Intermittent flexible wipers are adjusted by the driver according to the rain and sight conditions. The difference from the wipers on other ordinary cars is that it can automatically increase and decrease the wiper speed according to the change of vehicle speed. Because in the same amount of rainfall, the faster the vehicle speed, the more rainwater will be on the face, and if the car is stopped, the deceleration of the wiper will reduce the noise.

On rainy days, when the raindrops fall on the window glass, the line of sight in front of the car is quickly blocked, and vehicles, pedestrians and scenery become blurred. At this time, turn on the wiper, and the front of the car will be clear.

For example, the reason why the wiper is not clean: the reason why the wiper is always not clean is that there are invisible dirt on the glass. First, the car is parked in the downwind of the central air-conditioning cooling water tower. The cooling water tower sprinkles the particles after the water is torn on the glass to form small white spots. After drying, it is difficult to completely remove it; The mucus sticks to the car glass; the third is the mucus of insect corpses smashed by high-speed long-distance running. Because these things stick to the glass with water and a car cloth, it is difficult to completely remove (just can't see), forming uneven surfaces on the glass.

Since the current vehicle wipers adopt the design idea of double wipers, the corners of the front windshield of the car become the blind spot of the wiper, and a large amount of dust tends to accumulate at the corners of the front windshield of the vehicle after long-term use Other impurities need to be cleaned manually, causing inconvenience.

Contents of the invention

In order to solve the above problems, the present invention provides a simple structure, adopts the single wiper design idea, can realize the cleaning of the front windshield of the car without dead ends, and is convenient to replace and use. The technical solution:

A high-efficiency all-round wiper, the main body is a wiper, the front side of the front windshield of the car is set, the surface of the wiper is closely attached to the surface of the front windshield of the car, the wiper includes a wiper strip, a chute, a slider, a rotating bar and The rotating motor, the wiper strip is linear, the front side of the wiper strip is closely attached to the surface of the front windshield of the car, and is perpendicular to the bottom of the front windshield of the car, and the height of the wiper strip is equal to the height of the front windshield of the car. The back side of the wiper strip is provided with a chute with the same length as the wiper strip, and a slider is arranged in the chute, and the slider is fixedly connected with one end of the linear metal rotating bar, and the other end of the rotating bar is fixedly arranged on the rotating shaft of the rotating motor , the rotating motor is fixedly arranged in the middle of the lower edge of the front windshield of the automobile.

Further, the top opening of the chute is provided with a rubber plug, and the outer profile of one end of the rubber plug is the same as the cross-sectional shape of the inner cavity of the chute, and can be detachably installed on the top opening of the chute.

Further, the rotating bar is divided into a rotating bar A and a rotating bar B, both of which are linear structures. One end of the rotating bar A is fixedly connected to the slider, and the other end is flexibly connected to one end of the rotating bar B. The other end of the rotating bar B It is fixedly connected with the rotating shaft of the rotating motor; the rotating bar A can rotate around the connection with the rotating bar B in the range of 0~180°.

The beneficial effects of the present invention are:

(1) The present invention adopts the design idea of single wiper through the cooperative use of the wiper strip, chute, slider, rotating strip and rotating motor, which can realize the cleaning of the front windshield of the car without dead ends, and is convenient Easy to replace and easy to use. Its cleaning efficiency is high, and a large amount of dust will not accumulate on the corners of the front windshield of the vehicle during use, and no manual cleaning is required.

(2) The top opening of the chute in the invention is provided with a rubber plug, which effectively increases the structural stability of the wiper, and can prevent rainwater from seeping in from the top of the chute to cause corrosion inside the wiper, greatly improving the service life.

(3) As a preference, the rotating bar is divided into rotating bar A and rotating bar B, both of which are linear structures, which greatly improves the flexibility of the rotating bar, reduces the power of the rotating motor, and reduces the energy consumption of the wiper during use.
