Wiper rod pressure adjusting device, wiper rod and vehicle

Abstract

The invention discloses a wiper rod pressure adjusting device, which comprises an adjusting mechanism and a pressure detection device. The adjusting mechanism comprises an adjusting support, a swing cross beam, a reed assembly, a sliding connecting block and an adjusting bolt. A swing nut with internal threads is arranged in the swing cross beam, a head end of the swing cross beam is hinged to theadjusting support, and a tail end is connected to the reed assembly; the sliding connecting block is hinged to the adjusting support; the adjusting bolt is in threaded connection with the swing nut,and the lower end of the adjusting bolt is connected to the sliding connecting block, so that the adjusting bolt can rotate around the axis of the adjusting bolt relative to the sliding connecting block and cannot axially move relative to the sliding connecting block; the pressure detection device is used for detecting the pressure of a wiper rod. When the adjusting bolt rotates around the axis ofitself, the swing nut drives the swing cross beam to swing, therefore the elastic force exerted on the wiper rod by the reed assembly is adjusted. The invention further discloses a wiper rod and a vehicle using the wiper rod pressure adjusting device, and the wiper rod pressure adjusting device is adjustable in pressure and convenient to use.

Description

technical field [0001] The invention relates to an adjusting device, a wiper rod and a vehicle, in particular to a pressure regulating device for the wiper rod, a wiper rod and a vehicle. Background technique [0002] As an important safety part of the car, the wiper rod pressure has an important impact on the quality of the wiper. When the pressure of the scraper bar is too high or too small, it will cause problems such as scraper bar vibration, abnormal noise, and unclean scraping, which will affect the safety of use and user experience. Therefore, it is often necessary to detect and test the pressure of the designed wiper. [0003] In the wiper, the pressure of the wiper rod is determined by the structural size of the wiper arm, wiper rod and spring. Generally, after the assembly is completed, the pressure value is determined and cannot be adjusted. However, when inspecting and testing the produced wiper blades, it is often necessary to check the wiping performance of ...

AI Technical Summary

Problems solved by technology

[0006] One of the objects of the present invention is to provide a wiper rod pressure adjustment device, which can adjust the pressure of the wiper rod without being affected by the movement of the wiper, and adjust the pressure value accurately. It is quite convenient, and it also solves the problem that the pressure of the wiper rod cannot be adjusted after the wiper is installed
