Abstract
The utility model is a windshield wiper, capable of swinging to the angle of 180 degrees, and includes a drive motor, worm and worm wheel pairs and a connecting rod eccentrically positioned on the worm wheel; the other end of the connecting rod is rotationally connected with the wheel face of a rotary sector gear; the sector gear and a swing-arm gear are engaged. With the sector gear and the swing-arm gear which are engaged together, the utility model enlarges the wiping area of the windshield glass and improves the vision in rainy days.
Description
Technical field:
The utility model relates to vehicle accessory, particularly such as the improvement of vehicle wiper.
Background technology:
The wiper of Windshield comprises motor, retarder, four-bar linkage, rocker shaft, swept area of wiper blade assembly etc. before and after the automobile.Work as starter motor, motor shaft increases torsion effect through the deceleration of worm couple and drives rocking arm, and rocking arm drives four and connects machine mechanism and drive the rotating shaft that is installed on the dash shield and swing, and drives swept area of wiper blade wiper glass at last.Because the dead angle factor that produced of four jointed gear units, the general maximum pendulum angle of wiper is no more than 120 ° at present, and it is limited to control the visual field.What do preferably is the Citroen automobile, has adopted complicated connecting rod to increase pivot angle mechanism, and its maximum pendulum angle is 135 °.This also is a reason of respectively adorning a cover wiper before the positive front passenger's seat of present automobile, and manufacturing cost also improves naturally.
Summary of the invention:
The purpose of this utility model is the wiper that a kind of big pivot angle is provided for various transport facilitys.
The utility model comprises that drive motor, worm-gears, off-centre are installed in the connecting rod on the worm gear, it is characterized in that the other end of connecting rod is connected with the covering of the fan pivot pin of rotatable quadrant gear, quadrant gear and rocker gear engagement.
The utility model is because the rocker gear of quadrant gear being installed and being engaged with, when 2 times of the rocker gear numbers of teeth during to the quadrant gear number of teeth, when connecting rod runs to vertex from nadir; the rocker gear axle drives windscreen wiper rocking arm rotation half cycle; also be that swept area of wiper blade can be realized 180 ° the amplitude of oscillation; blow the rain area on the Windshield thereby increased, improved the rainy day visual field.When this wiper being installed in the middle of the Windshield, can only overlap wiper before the then positive front passenger's seat with one.Certainly, if certain vehicle are circular form, then design the rocker gear number of teeth and equal the quadrant gear number of teeth, the windscreen wiper sheet just can be realized 360 ° of circumference rotations.
Description of drawings:
Accompanying drawing has been represented the utility model structure principle chart.
The specific embodiment:
With reference to accompanying drawing.The motor shaft of drive motor 1 is made worm screw 2, and the worm gear 8 that is engaged with constitutes deceleration force amplifier mechanism.Connect connecting rod 9 lower ends at worm gear 8 eccentric pivot pins.The quadrant gear 3 that is installed in worm gear 8 tops can rotate around axle 4, and meshes with rocker gear 6.Be connected by pivot pin 7 with connecting rod 9 upper ends on quadrant gear 3 wheel faces.During work, transmission of power by worm-gears, the moving circle of worm gear 8 revolutions, connecting rod 9 drives quadrant gear 3 and up and down reciprocatingly rotates once, as long as quadrant gear 3 numbers of teeth are not less than 1/2nd of rocker gear 6 numbers of teeth, the rocking arm and the swept area of wiper blade (not drawing among the figure) that are driven by rocker shaft 5 can guarantee to realize at least 180 ° the amplitude of oscillation.
Claims (1)
1, a kind of wiper of realizing 180 ° of pivot angles, comprise that drive motor (1), worm-gears (2), off-centre are installed in the connecting rod (9) on the worm gear, the other end that it is characterized in that connecting rod (9) is connected by pivot pin (7) with the covering of the fan of rotatable quadrant gear (3), quadrant gear (3) and rocker gear (6) engagement.
