The main switch is controlled by the driver to open and close all the glass windows, and the sub-switches on the handles in the doors are controlled by the passengers to open and close all the glass windows, so that the operation is very convenient. One important characteristic in the performance of motorized window lifters is the stopping force. The locked-rotor force directly reflects the force generated when the window glass is inserted into the upper sealing strip, if the force is too small, the sealing formed between the glass and the sealing strip is not tight enough, and the glass can shake, leak air and generate noise in the driving process of the vehicle; however, if this force is too large, it may damage the sealing tape in a short time, and it is also said that the torque of the motor is selected to be too large in design, resulting in a waste of manufacturing cost. Therefore, the measurement of the stalling force of the electric window lifter plays an important role in indicating in the development of the lifter system.
At present, no fixed measuring equipment exists in the field of measurement of the stalling force of the electric glass lifter in China. Two main methods are used in the measurement, one is to use a push-pull dynamometer to perform the test, and specifically, the glass is extruded by the push-pull dynamometer in the process of rising to obtain a measured value; the other is to use a mechanism similar to a spring balance, and the force value is measured by the same way of pressing the glass upwards. The former is convenient, but has the problems that different push-pull force meters have different shapes, the distance between the glass and the upper sealing strip is not fixed and the push-pull force meter deflects when the glass is extruded, and the approximate rigid collision does not buffer when the glass is extruded, so that the measured value is inaccurate and unstable, and the repeatability is poor; although the latter solves the buffering problem to a certain extent, the reading is inconvenient, and the attenuation of the spring is a factor influencing the measuring result. Meanwhile, the data comparability between different methods is poor due to the inconsistency of the test modes.
