Plastic part of automobile wiper and preparation method thereof

Abstract

The invention discloses a plastic part of an automobile wiper and a preparation method thereof. The plastic part of an automobile wiper includes a power assembly, wherein the power assembly comprisesa drive motor; the upper end of the drive motor is connected with a drive gear; a linkage gear engaged with the drive gear is arranged on the right side of the drive gear; the upper end of the drive gear is connected with a power rotating core; a power transmission frame is connected to the power rotating core; a drive bent lever is connected between the power rotating core and the power transmission frame; the lower end of the power transmission frame is provided with a wiper head parallel to the power transmission frame; the wiper head includes a wiper holder; a rubber brush body is arrangedin the wiper holder; the left side of the wiper holder is provided with a gas ejection tank; and a liquid spraying metal pipe is arranged on the right side of the wiper holder. The plastic part of anautomobile wiper utilizes the air path system to ensure that there is no dead angle in the working process of the wiper to remove the rainwater from the glass surface, and utilizes the liquid path system to ensure that the stains which are difficult to clean are easily removed. The plastic part of an automobile wiper not only solves the problem that the heat of the front box is difficult to remove, but also is effectively used for removing the dust.

Description

technical field [0001] The invention relates to the technical field of automobile wipers, in particular to a plastic part of an automobile wiper and a preparation method thereof. Background technique [0002] The main function of the car wiper is to scrape off the dirt attached to the windshield to ensure a clear view of the driver. The car wiper system basically includes two systems of "brushing" and "washing", and even some wiper systems have combined these two parts. functions are integrated. But the main components of the "brush" include electric motors and motor controllers, wiper linkages, wiper arms, and wiper blades. Now the most common wiper system moves by a crank connecting rod to push and pull a group of four-bar linkages. The two wiper arms of the four-links belong to the input rod and the output rod respectively, and the entire connecting rod group forms a six-bar linkage. . The design of the wiper mechanism requires sweeping the largest area and range as po...

AI Technical Summary

Problems solved by technology

[0007] Existing car wipers mostly use two wipers to do fan-shaped movement or left-right translation movement. The slow speed of translation movement requires a long connecting rod, which affects the driver's sight when the wiper is working. The traditional fan-shaped movement wiper cannot cover the entire windshield. Scrub evenly

Moreover, the material of the existing wiper needs to experience severe cold, heat, wind, sun, and is prone to aging and cracking, or the hardness increases, the elasticity decreases, and the quality of the brushing decreases, which is difficult to meet the quality and function requirements of modern automobiles.
