Problems solved by technology

[0003] The car window shaker is a device used to raise or lower the car window. The use of the single-rail window shaker greatly reduces the cost of parts, but in the long-term use process, the single-rail window shaker is prone to failure and abnormality. Through analysis, the reason for the above defects is that during the lifting process of the window shaker, the glass is sideways toward a certain column, which causes friction between the glass and the bead. After a long time, the system wears seriously, causing the glass to vibrate or even get stuck.

Embodiment

[0026] as attached figure 1 As shown, a method for designing the balance structure of a single rail window shaker system is characterized in that it includes the following steps:

[0027] The first step is to analyze the force of the window shaker:

[0028] Suppose the frictional force on the glass of the left column of the window shaker is f B ;

[0029] Let f C ;

[0030] Let the friction force of the guide groove on the left glass of the window shaker be f 左 ;

[0031] Let f 右 ;

[0032] Let Δ be the distance from the center of gravity of the glass to the center of the pin circle of the window shaker;

[0033] The second step is to analyze the ideal state torque of the window shaker:

[0034] According to the torque formula M=FL, when the glass of the window shaker rises, it overcomes the gravity, and the glass is subjected to the friction torque sum: ∑M=f B ·a+f 左 ·a / 2+G·Δ-f 右 b / 2-f C b. To overcome the gravity when falling, the glass is subjected to the frict...

Abstract

A design method for the balance structure of a single-rail window shaker system, which takes into account failure factors during design, improves the rationality of the single-rail window shaker system structure, and makes the glass of the window shaker move up and down within the gap of the batten system , the mutual friction becomes extremely small, the system noise is reduced, and the operating life is increased.

Description

technical field [0001] The invention belongs to the technical field of auto parts structure, and in particular relates to a design method for a balance structure of a single-rail window-operating machine system, which can maintain the dynamic balance of the single-rail window-operating system. Background technique [0002] In recent years, with the rapid development of my country's economy, my country's automobile industry, especially the car industry, has been on the track of rapid development. Cars have gradually entered the homes of thousands of households and become a means of transportation that people often use in daily life. In order to meet the strong demand for cars, major automobile manufacturers continue to expand the production of cars and continue to launch various car brands. The output of cars is developing in a blowout manner, which requires that each segment of car production must be fast to meet the needs of the market. In mass production, automobile manufa...
