Abstract

The invention discloses an automatic frost spraying device for an automobile defrosting test, and the device comprises a nozzle which is connected with a nozzle connecting seat through a telescopic adjusting mechanism, the nozzle connecting seat is connected with a longitudinal adjusting mechanism and a transverse adjusting mechanism, and the longitudinal adjusting mechanism and the transverse adjusting mechanism are in sliding fit with a frame. The frame is connected with the fixing support through the angle adjusting mechanism, a positioning measuring device is fixedly arranged on the frame, and the telescopic adjusting mechanism, the transverse adjusting mechanism, the longitudinal adjusting mechanism and the positioning measuring device are all in communication connection with the adjusting mechanism controller. The invention further provides a control method of the automatic frost spraying device for the automobile defrosting test, and the control method comprises the steps of measuring the coordinates of the automobile window glass and the spray head, determining the target distance between the spray head and the automobile window glass, the target moving speed of the spray head and the target walking track coordinates of the spray head, and controlling the adjusting amount of the telescopic adjusting mechanism, the transverse adjusting mechanism and the longitudinal adjusting mechanism. The spraying time of the nozzle is shortened, and the working efficiency of low-temperature spraying is improved.

Description

Technical field [0001] The present invention relates to the field of automobile defrosting technology, and specifically refers to a car defrosting test automatic francing device and control method. Background technique [0002] After the vehicle is parked in a very low temperature area, the external wet air condenses ice on a lower temperature window. In order to travel safely, the air conditioning system of the vehicle needs to have certain defrostability. The defrosting test is to simulate this user usage, and is also an important safety law in the vehicle test. According to the provisions of "GB11556" and "GB / T24552", the method of currently implementing the defrosting test is mainly divided into -18 ° C low temperature dip car, front stop and side window glass spray, dipped car icing and open air conditioning defrost, etc. step. Among them, the operation of the front and side-shaped glass spray is required to be deployed at very low temperature -18 ° C, and the instrument u...
