Automotive windshield wiper

Abstract

The invention provides an automotive windshield wiper, which belongs to the technical field of automobiles, and solves the problem that a windshield wiper arm assembly of an existing automobile cannot be quickly disassembled and assembled without tools. The automotive windscreen wiper comprises a shaft sleeve fixed onto a frame, a rotating shaft capable of rotating in the shaft sleeve is arranged in the shaft sleeve, one end of the rotating shaft is connected with a windshield wiper arm, the other end of the rotating shaft is connected with a driving mechanism through a hollow shaft, the hollow shaft is sleeved on the rotating shaft and rotatably connected into the shaft sleeve, and a connecting device leading the rotating shaft to be detachably connected into the hollow shaft is arranged between the hollow shaft and the rotating shaft. The automotive windshield wiper has the advantage that windshield wiper arm assembly can be quickly disassembled and assembled without tools.

Description

technical field

[0001] The invention belongs to the technical field of automobiles and relates to an automobile wiper. Background technique

[0002] When it rains, the wipers on the front windshield of the car will move in unison, and the two wiper blades will cyclically swing around the fixed rotating shaft column to scrape the rainwater from the front windshield and return the driver a clear and effective vision.

[0003] The earliest wipers consisted of a rocker arm and an arm with a squeegee blade, which were manually operated by the driver. Later, in order to see the needs of the position, wiper arms were installed on the left and right sides, connected with connecting rods, and became manual double wiper blades, which is the original type of today's car wiper.

[0004] Later wipers used air pressure difference instead of manpower, called vacuum wipers. Use a pipe to connect to the engine, use the vacuum of the engine to drive the piston inside the wiper, push the sw...

Embodiment 2

[0040] The structure of this automobile windshield wiper is basically the same as embodiment one, and the difference is that Figure 6 As shown, the supporting device 41 includes a spring seat 411 fixedly connected to one end of the hollow shaft 2, the spring seat 411 is threaded on the hollow shaft 2, and a spring 412 is arranged between the spring seat 411 and the rotating shaft 3. One end of 412 is fixed against the spring seat 411 to prevent the spring 412 from falling out when the rotating shaft 3 is pulled out, and the other end is against the above-mentioned rotating shaft 3 . The inner diameter of the section of the hollow shaft 2 where the spring 412 is placed is consistent with the inner diameter of the place where the rotating shaft 3 is inserted, so that the processing of the hollow shaft 2 is more convenient. The dismounting method of this automobile windshield wiper is identical with embodiment one.
