Wiper shaft assembly structure and automobile

Abstract

The invention provides a wiper shaft assembly structure and an automobile, relating to the technical field of automobiles, comprising a wiper spindle, a sleeve assembly, a wiper rocker arm, a coil spring and an electromagnet. A receiving cavity is provide inside that sleeve assembly, A main shaft of that wiper passes through the receive cavity, and extends along both ends of the sleeve assembly inthe longitudinal direction, A helical spring is positioned within that receive cavity, the end of the electromagnet near the spindle of the wiper, By detecting a collision between a vehicle and a pedestrian at the front of the vehicle, The automobile ECU sends a signal to the electromagnet, and the electromagnet generates an attraction force, the attraction force overcomes the spring force of thecoil spring, and the wiper spindle moves downward under the electromagnetic attraction force of the electromagnet, thereby alleviating the lack of lateral stiffness or poor durability of the supportin the prior art, and is prone to fatigue fracture phenomena; As well as the technical problems of small buffer space, non-repeatability and high replacement cost; It makes a lot of room for pedestrians to play a very good role in protecting.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to a wiper shaft assembly structure and an automobile. Background technique [0002] With the rapid development of automobile technology, the protection of pedestrians by automobiles has attracted more and more attention and attention from the people, automobile companies and relevant state agencies. National standards, C-NCAP, Euro-NCAP, etc. also put forward requirements and test methods for pedestrian protection of vehicles. Wipers, also known as wipers, water dials, wipers or windshield wipers, are used to wipe off Equipment for raindrops and dust on the windshield of vehicles to improve the visibility of drivers and increase driving safety. Due to the high rigidity of the wiper shaft of the car, in the collision between the vehicle and the pedestrian, the head of the pedestrian will hit the wiper shaft. In this case, the wiper shaft will generate a large reaction force on ...
