The rivet is assembled on the swing arm, a swing arm shaft sleeve and a transmission connecting rod, and then a waterproof cover is covered on the swing arm to effectively prevent water. The utility model discloses a swing arm axle sleeve and drive connecting rod assemble riveting back in addition dedicated waterproof shroud, increase the waterproof performance between swing arm axle sleeve and the drive connecting rod to solve the entering of rivers and foreign matter in swing arm and the drive connecting rod motion process, guaranteed that drive performance and wiper scrape scraping of arm assembly brush quality and reliability.
Description
Technical Field
The utility model relates to an automobile windscreen wiper, in particular to link mechanism of windscreen wiper.
Background
At present, a wiper (also called a wiper) is an indispensable component of an automobile, and a wiper arm assembly of the wiper receives power transmitted by a wiper motor and a link mechanism and simultaneously generates a wiper arm pressure, and a wiper blade wipes and brushes a glass so as to clean foreign matters on the glass. The link mechanism is used for receiving the power of the wiper motor and transmitting the power to the wiper arm after forming a certain angle. The assembly process of the link mechanism of the windscreen wiper is characterized in that the swing arm and the transmission link are connected through rivets, a waterproof structure is not processed at the matching position of the swing arm and the transmission link, and the rotating part of the swing arm is easy to enter water flow. After the swing arm is subjected to injection molding, the rivet and the through hole of the swing arm shaft sleeve are assembled, and then the transmission connecting rod is riveted with the rivet; because the friction force and the swinging force of more than 150 thousands of times of movement need to be borne at the position, the precision control is higher, and the gap after riveting and matching needs to be ensured, no water flow can enter the matching position of the rivet and the shaft sleeve of the swinging arm, otherwise, the abrasion of a plastic part can be increased, and the failure of a transmission mechanism is caused.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to overcome foretell technique not enough, and provide a waterproof formula link mechanism who possesses wiper that waterproof flow got into.
The purpose of the utility model can be realized through the following technical scheme: the waterproof connecting rod mechanism of the windscreen wiper comprises a swing arm, a transmission connecting rod and a rivet, wherein a swing arm shaft sleeve is arranged on the swing arm and at the contact position of the swing arm and the transmission connecting rod, and waterproof covers are respectively arranged at two ends of the swing arm shaft sleeve and the transmission connecting rod.
The rivet is assembled on the swing arm, a swing arm shaft sleeve and a transmission connecting rod, and then a waterproof cover is covered on the swing arm to effectively prevent water.
Adopted the utility model discloses behind the technical scheme, swing arm axle sleeve and drive connecting rod assemble riveting back in addition dedicated waterproof shroud, increase the waterproof performance between swing arm axle sleeve and the drive connecting rod to solve the entering of rivers and foreign matter in swing arm and the drive connecting rod motion process, guaranteed that drive performance and wiper scrape scraping of arm assembly brush quality and reliability.
