detailed description

The utility model will be described in further detail below in conjunction with the accompanying drawings, so that those skilled in the art can implement it by referring to the description.

As shown in FIG. 1 , the utility model provides an automobile single wiper system, which includes a crank rocker mechanism, a motor 140 , a swing sleeve 150 , a wiper rod 160 and a guide rail 170 .

Described crank rocker mechanism is made up of crank 110, connecting rod 120, rocking bar 130 and frame. The frame can be omitted after one end of the crank 110 and one end of the rocker 130 are respectively hinged with fixed parts.

The crank 110 is connected with the motor 140, and is driven by the motor 140 to perform circular motion, while the rocker 130 performs swing motion between left and right limit positions.

As shown in FIG. 2 , a swing sleeve 150 is fixedly connected to the crank 110 , and a guide hole 151 is opened on the swing sleeve 150 . The axis of the guide hole 151 is parallel to the length direction of the crank 110 . That is, when the crank 110 swings between the left and right limit positions, the swing sleeve 150 also swings along with the crank 110, and the speed and angle of the swing sleeve 150 degrees are the same as the swing speed and angle of the crank 150. same.

The main body of the wiper lever 160 is cylindrical, and the wiper lever 160 passes through the guide hole 151 on the swing cover 150 and matches with the guide hole 151, so that the wiper lever 160 can slide relative to the swing cover 150, and the wiper lever 160 The rod 160 will swing together with the pendulum sleeve 150 .

The automobile single wiper system provided by the present invention further includes a guide rail 170 which is U-shaped and symmetrical. A pulley 161 is disposed at the bottom end of the wiper rod 160 , and the pulley 161 cooperates with the guide rail 170 so that the pulley 161 can slide along the guide rail 170 .

The swing angle of the rocker 130 is symmetrical to the left and right, with the vertical line passing through its swing center as the axis of symmetry. When the rocker 130 is in the vertical direction, the wiper rod 160 is also in the vertical direction. At this time, the pulley 161 is in the vertical direction. The bottommost end of the guide rail 170. At this time, the part of the wiper rod 160 protruding out of the swing sleeve 150 is the shortest, and the top of the wiper rod 160 will not exceed the upper edge of the windshield of the car.

When the rocker 130 swings to the left, it drives the swing cover 150 to swing to the left together with the wiper rod 160 . At this time, the pulley 161 will slide upward and right along the guide rail 170 due to being restricted by the guide rail 170 . The guide rail 170 is designed to be similar to an ellipse. The purpose is to make the wiper rod 160 slide upward relative to the swing sleeve 150 during the swing process, that is, the part of the wiper rod 160 protruding from the swing sleeve 150 will gradually become longer. This arrangement has a larger wiping area compared with conventional fan-shaped swing wipers. As shown in FIG. 3 , the swing path of the outer edge of the wiper lever 160 of a conventional wiper is an arc-shaped path 181 , ie, the center of the circle is the swing center of the rocker 130 . In the automobile single wiper system provided by the present invention, the wiper lever 160 also takes the swing center of the rocker 130 as the swing center, but because in the swing process, the equivalent swing radius is gradually increasing, so the outer edge of the wiper lever 160 swings The path is a quasi-elliptical path 182 . Therefore, compared with conventional wipers, the single wiper system for automobiles provided by the present invention has one more wiper area in the upper left corner. Therefore, the single wiper system for automobiles provided by the present invention has a better wiper effect.

Since the left and right swing angles of the rocker 130 are symmetrical, the guide rails 170 are arranged symmetrically, so when the rocker 130 swings to the right it is the same as when it swings to the left.

The present invention achieves the wiping performance of the traditional double wiper through the arrangement of the single wiper, and overcomes the shortcomings of the lack of space for small and miniature cars and the difficulty of installing the double wiper system. The present invention only has one wiper lever, which saves space and manufacturing cost. At the same time, in terms of performance, compared with the traditional single wiper system, the swing angle and length of the wiper rod are limited by the guide rail and the guide hole. Enlarged, the outer edge of the wiper rod forms a quasi-elliptical outline, which increases the wiping area compared with the arc-shaped outline of the traditional single-wiper system, and overcomes the defect of insufficient wiping area of the conventional single-wiper system. At the same time, it reduces the obstruction of rainwater to the driver's field of vision, so that the glass cleaning device can play a better role and increase the cleaning area. By changing the shape of the rails, the existing dual wiper system can be replaced. Compared with the double wiper system, the utility model reduces the number of wipers, and the requirement for driving force is also reduced, so that the electronic system of the vehicle body is more energy-saving.
