Embodiment Construction

[0021] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0022] figure 1 It shows the outline drawing of the test bench, which has a touch screen for setting and display on its surface, and also has a start switch and an indicator light. There are two sockets on its side, one of which is the power inlet 1 of the whole machine, and the other is the detection Signal exit 2.

[0023] figure 2 It shows the internal structure of the test bench, in which Siemens S7-200PLC is used as the central processor to process the data detected by the detection units AU1 and AU2, and control the contactors KM1 and KM2 respectively, and then realize the processing of electric windows lift control. The detection units AU1 and AU2 are used to detect the current and voltage output to the glass lift motor, so as to adjust the motor speed and cut off the motor. Contactors KM1 and KM2 control the start and stop of the glass lift motor. U1 an...

Abstract

The invention provides an electric power window lifting test bed and a test method. The test bed comprises: a touch screen, a start switch and an indicator light which are arranged on a panel; a socket on the lateral surface of the test bed; and a central processor, a detection unit, a contactor, an entire machine power supply and a lifter motor power supply which are arranged in the test bed, wherein the detection unit is used for detecting the current and voltage output to a glass lifting motor, and the contactor controls the start and the stop of the glass lifting motor. A control device and the detection device are used to detect all the lifting parameters of the electric power window like the control function on a whole vehicle and count without manual intervention. Therefore, whether a whole vehicle glass lifting system satisfies the design performance requirements of products or not, is monitored and evaluated and the fault phenomena such as glass lifting difficulty and abnormal noise are analyzed by the technical personnel in aid of the test bed.

Description

technical field [0001] The invention belongs to the field of automobile manufacturing, and in particular relates to an electric window lift test bench and a test method. Background technique [0002] In the automotive industry, firstly, the produced window regulator motors need to be inspected, and secondly, after the assembled vehicle door or the whole vehicle is sold, there will be phenomena such as insufficient lifting and abnormal lifting, which affect the user's trust in the product. degree and satisfaction, but the solution to these problems has become a persistent problem. Although it can be assembled with high-quality spare parts, this phenomenon cannot be avoided. Contents of the invention [0003] In order to solve the above-mentioned problems, the present invention provides an electric window lift test bench, comprising: [0004] Touch screen, start switch and indicator light set on the panel; [0005] The socket set on the side; and the central processing un...
