Problems solved by technology

Due to wind interference, the pressing force of the wiper is different at different speeds of the vehicle, and may even rise and break away from the surface of the window glass, affecting the safety of the vehicle at high speed
Therefore, wind tunnel experiments are required to test the compressive force performance of the wiper at high vehicle speeds during the design of the wiper. The current measuring device for the compressive force of the wiper is limited to static measurement, and cannot accurately measure the pressure distribution and the compressive force of the scraping area. Variations with vehicle speed

Abstract

The invention discloses a wind tunnel test device of windscreen wiper pressing force distribution. The device comprises a supporting frame, laminated glass, a windscreen wiper, a rotary shaft, a water spraying nozzle, a water tank and a sensor array, wherein the laminated glass comprises an outer glass thin layer and an inner glass layer; the windscreen wiper is arranged on the outer side of the laminated glass and comprises a windscreen wiper arm, and the windscreen wiper arm is arranged on the surface of the outer glass thin layer in an attached mode; the rotary shaft is arranged at one end of the windscreen wiper arm, and the windscreen wiper arm can rotate around the rotary shaft; the water spraying nozzle is arranged at the other end of the windscreen wiper arm; the water tank is arranged at the lower end of the device and connected with the water spraying nozzle through a water pump; the sensor array is arranged between the outer glass thin layer and the inner glass layer. The technical purpose is to provide a wind tunnel test device of windscreen wiper pressing force distribution. According to the pressure of different scraping areas, the state of the windscreen wiper pressing force distribution and the change rule of windscreen wiper pressing force with wind speed are obtained, and a reference is provided for design and improvement of the windscreen wiper; a windscreen wiper controlling method is also provided, the change rule of the windscreen wiper pressing force with vehicle speed is measured based on the wind tunnel test of the windscreen wiper, and the pressing force of the windscreen wiper arm is adjusted through the magnitude of a current, so that a better scraping effect is obtained.

Description

Technical field [0001] The invention relates to the field of automobiles, in particular to a wind tunnel test device for the pressure distribution of a wiper wiper and a wiper control method. Background technique [0002] The pressing force of the wiper when the vehicle is traveling at different speeds is an important performance index to measure the wiper. Due to the interference of wind, the pressing force of the wiper at different vehicle speeds is different, and it may even rise and separate from the surface of the window glass, which affects the safety of the vehicle at high speed. Therefore, when designing the wiper, it is necessary to conduct a wind tunnel test on the pressing force performance of the wiper at high speeds. The current wiper pressing force measurement device is limited to static measurement and cannot accurately test the pressure distribution and pressing force of the wiper area. Changes with the speed of the vehicle. Summary of the invention [0003] The ...
