Problems solved by technology

At present, the usual way of connecting the output shaft 111 and the scraper arm seat 103 is to match the splines on the hole shafts of the two, and then fasten the output shaft 111 and the scraper arm seat 103 through bolts and nuts, but this connection method The mating surface between the wiper arm seat 103 and the output shaft 111 is prone to slippage, so that the output shaft 111 cannot drive the wiper arm assembly 10 to swing, resulting in failure of the wiper mechanism

Abstract

The invention provides a windscreen wiper mechanism which comprises a wiper arm seat base body, a matching part and an output shaft. The output shaft comprises a shaft base body, a shaft shoulder arranged at one end of the shaft base body and a groove formed in the axial direction of the shaft shoulder. A blind hole in clearance fit with the shaft shoulder is formed in the bottom face of one end of the wiper arm seat base body, a key groove is formed in the side wall of the blind hole, and the matching part is embedded in a cavity formed by the groove and the key groove. The windscreen wiper mechanism further comprises a locking part used for preventing the matching part and the cavity from separating, and the locking part can be fixedly connected with the wiper arm seat base body. According to the windscreen wiper mechanism, the output shaft can provide stable and reliable force for a wiper arm assembly, and the problem of failures of the windscreen wiper mechanism is solved.

Description

technical field [0001] The invention relates to vehicle component technology, in particular to a wiper mechanism. Background technique [0002] In the existing technology, such as figure 1 As shown, the wiper mechanism mainly includes two parts: the wiper arm assembly 10 and the motor linkage bracket assembly 11, and the wiper arm assembly 10 includes the wiper blade assembly 101, the wiper arm 102 and the wiper arm seat 103 connected in sequence, the motor The connecting rod bracket assembly 11 includes an output shaft 111 , which is connected to the scraper arm base 103 to drive the scraper arm assembly 10 to swing. At present, the usual way of connecting the output shaft 111 and the scraper arm seat 103 is to match the splines on the hole shafts of the two, and then fasten the output shaft 111 and the scraper arm seat 103 through bolts and nuts, but this connection method The mating surface between the wiper arm base 103 and the output shaft 111 is prone to wire slippin...
