Description
Technical field
The invention belongs to automobile technical field, relate to a kind of vehicle wiper.
Background technology
Sometimes When It Rains, the wiper on shield glass will trimly move, and two rain shaving blades are done circulation and swung centered by the rotating shaft post of fixing, and the rainwater of front windshield are scraped off, also clear actv. visual field of driver.
The wiper of very early time is comprised of a rocking arm and the arm that accompanies rubber scraping blade, by driver's manual operations.In order to see the needs of position, in the left and right sides, all loaded onto and scraped water arm afterwards, with connecting rod, connected, become manually two swept area of wiper blades, namely today vehicle wiper archetype.
Wiper afterwards replaces manpower with draught head, is called vacuum wiper.With a pipe, receive driving engine, utilize the degree of vacuum of driving engine to drive the piston of wiper the inside, promote swing arm and rotate, rain shaving blade just can move.At the initial stage forties, electric windshield wiper has been installed on automobile successively and has been replaced vacuum wiper.
Wiper assembly generally comprises electrical motor, retarder, four-bar linkage, wiper arm, rain shaving blade assembly etc., and wiper arm assembly comprises floating rule and scraping arm, when driver opens wiper, electrical motor increases torsion effect driving swing arm through the deceleration of worm and gear, swing arm drives four-bar linkage, four-bar linkage drives the rotating shaft being arranged on front coaming plate to swing, and finally by rotating shaft, drives rain shaving blade to sweep Windshield.The complex structure of whole wiper and tight, needs instrument and is sought after the time during dismounting.
Military cross-country car also needs to assemble wiper, but do the vibration that wartime, bomb blast brought and can make to be assemblied in the wiper damage on cross-country car, simultaneously, owing to fighting, need, at cross-country car, arrive behind operation place, operating personal need to not disassemble wiper arm assembly rapidly in the situation that there is no dismantling devices in 3 seconds, and operation need to not install wiper arm assembly rapidly after finishing in the situation that there is no dismantling devices in 3 seconds.
A kind of detachable windscreen wiper has been announced in Chinese utility model patent application (201120227350.3), comprise floating rule, floating rule and slewing arrangement, on slewing arrangement, be also provided with an auxiliary floating rule, one end of floating rule and auxiliary floating rule is arranged on slewing arrangement, the other end of floating rule is connected with one end of scraping arm, one end away from itself and floating rule junction on scraping arm is provided with connector, the rotating riveted joint of connector is arranged on scraping arm, scraping arm is provided with bayonet lock, connector is provided with the opening coordinating with bayonet lock, when opening props up mutually with bayonet lock, connector can not rotate towards bayonet lock direction, connector is provided with connecting pin, in scraping arm, be provided with scraping arm fluting, in scraping arm fluting, be provided with extension spring, extension spring one end is connected with connecting pin hook, the extension spring other end and floating rule hook get up.This detachable windscreen wiper can take off extension spring from connecting pin and floating rule, thereby realizes the dismounting of scraping arm, is convenient to practical personnel inspection and maintenance, very convenient.But this wiper can only carry out dismounting by scraping arm, cannot be to scraping arm fast speed dismounting together with floating rule.
Summary of the invention
