Fatigue test equipment for switch speed regulating device of automobile air conditioner

Abstract

The invention discloses a fatigue test device for a switch speed regulating device of an automobile air conditioner. The guide rail on the top is slidably connected, the slider is movable and hinged with a swing block, the swing block is provided with a chuck, and the chuck is connected with the speed regulating switch shaft; the swing block is provided with a counting sensor, and the counting sensor and the motor are respectively electrically powered. A controller is connected, and the controller is connected with a display. Beneficial effects of the present invention: set the motor to drive the connecting rod to rotate, and drive the slider to slide on the track, and finally drive the swing block to swing, and simulate the operation of the speed control switch in actual use through the swing of the swing block, so as to realize the control of the speed control switch The fatigue test of the device has a simple structure and low cost; and by setting a counter, a controller and a display, the test bench can monitor and display relevant parameters in real time.

Description

technical field [0001] The invention relates to the technical field of experimental equipment, in particular to a fatigue test equipment for an automobile air conditioner switch speed regulating device. Background technique [0002] In the fan speed regulating device of automobile air conditioner, the adjustment of air volume is realized by changing the winding speed regulating resistor of the fan. When the fan does not run normally and stops, the knob switch in the speed regulating resistor may be out of gear or skip gear, resulting in a rapid increase in the current flowing through it. The high temperature has a great damage effect on the casing of the automobile air conditioner, the fan impeller, etc., and may even cause more serious consequences. In order to avoid the occurrence of the above situation, the automobile air conditioner needs to carry out the fatigue test on the switch speed regulating device after the manufacture is completed. [0003] At present, the fat...
