Embodiment Construction

[0034]This embodiment is a wiper reset device, including a gear 1, a connecting rod 7, an eccentric bush 9, a coil spring 13, and a barrel 12; wherein, the eccentric bush 9 is set on the eccentric shaft 19 at one end of the gear, One end of the connecting rod 7 is sleeved on the eccentric bushing; the barrel 12 is sleeved on the eccentric bushing, and the inner end surface of the barrel is attached to the outer end surface of the connecting rod. One end of the coil spring 13 is hung on the lug on the end surface of the eccentric bushing, the other end is located on the end surface of the connecting rod, and is hung on the fourth small shaft 8 fixedly connected to the connecting rod. The clockwork cover plate 14 fits on the eccentric shaft and is used to limit the axial position of the coil spring. A third small shaft 6 is installed at the outer edge of the end face side of one end of the eccentric shaft 19 on the gear 1, and the block 3 is sleeved on the third small shaft. On...

Abstract

The invention relates to a windshield wiper reset device. On the basis that a motor outputs forward and reverse rotation motion and a speed reducer decelerates to drive a crank-rocker mechanism to work, a set of mechanism for changing crank eccentricity is added. The mechanism cooperates with the forward and reverse rotation switching of the motor through a coil spring and a reed under the circumstance of respective elastic combination, and drives the instantaneous rotation of the crank by certain angle so as to achieve change of the crank eccentricity, the whole process is completed in a moment, and finally two sets of crank-rocker mechanisms are formed. Under the action of the two sets of crank-rocker mechanisms, the purpose of difference between the wiper working area position and docking position of the windshield wiper is finally realized, and the added set of mechanism for changing crank eccentricity causes slight increase of the total product weight and no volume change, the windshield wiper reset device solves the problem that when the windshield wiper is not in use, the outer structure shields part of the view of a driver, endows the driver with more extensive view, and relieves driving fatigue.

Description

technical field [0001] The invention relates to a wiper reset device. Background technique [0002] The use of fluid kinematics and structural strength is considered in the external design of the aircraft. The products installed externally are required to be relatively smooth. The wiper not only needs to be able to wipe a larger windshield area in rainy days, but also when the wiper is not in use, its docking position should not block the windshield of the aircraft as far as possible. At present, when the traditional aircraft is not working, the wiper The docking position is at an extreme position of its working area. When it is parked on the windshield of the aircraft, when the wiper is not in use, its external structure will block part of the windshield. At the same time, part of the pilot's field of vision is also blocked by the wiper. The external structure is blocked, which is easy to observe the driver's fatigue, easily make the driver irritable, and have an impact on...
