The car window glass lifter is used as an automobile part, the main function is to realize the stable lifting of the car window glass, the internal system of the car door is precise and complex, and the car door glass lifter also comprises a metal plate, a sound box, glass, a door lock, a door lamp and a controller for controlling electronic components in the car. At the moment of opening and closing the vehicle door, the vehicle door integrally receives huge impact force by taking the vehicle door hinge as a fulcrum. The glass lifter system (including motor, glass) is the biggest mechanism except the panel beating in the door system, and the glass lifter is the only system that needs to realize continuous motion in the door system. In order to ensure the stability of the overall system, it is generally considered to arrange the glass lifter system with the most precise and massive motor near the door hinge, taking into account the distribution of the door mass.

Detailed Description
Comprises the following steps:
the first layer is a metal plate 7, the second layer is a B inhaul cable 1, and the third layer is a C inhaul cable 3;
as shown in fig. 1 and 2, selecting a center position with the largest amplitude of a B cable 1 with a spring 5 at one end, penetrating the center position into a lower layer of a layering control ribbon 2 by clearance fit, as shown in fig. 3, inserting the layering control ribbon 2 into a vehicle door sheet metal 7 by interference fit, and connecting a C cable 3 without springs at two ends with an upper layer of the layering control ribbon 2 by interference fit;
(II) determination of opening size L of layered control band 2
Because the whole stress condition of the vehicle door is very complex, completely and accurately calculating the data of the whole movement of the stay cable is basically impossible to realize, from the angle of industrial engineering application, according to the data of repeated measurement and calculation and experiment,
(1) any cross section of the B inhaul cable 1 is repeatedly bent, the model of the stretching motion is in longitudinal vibration and is always kept as a plane, and each point on the cross section moves in the same displacement in the axial direction, namely rigid motion;
(2) in the process of longitudinal movement, the transverse deformation caused by the longitudinal extension and contraction of the B inhaul cable 1 is ignored;
(3) the integral stress model of the B stay cable 1 is an elastic support, one section of the B stay cable 1 is an elastic support and is set as the right end, and the axial internal force is equal to the elastic force; as shown in fig. 8.
A coordinate system is established by taking the left end of the inhaul cable as a coordinate origin, a infinitesimal section dx is taken at a position where the coordinate is x, and at any moment t, the displacement and the cross-section internal force at the two ends of the infinitesimal section are as follows:
at x, the cross-sectional displacement is Y (x, t), and at x + dx the displacement is
Then the absolute deformation of dx is
Strain of
A is the cross section area of the stay cable, rho is the density of the stay cable, alpha is the propagation speed of longitudinal waves in the stay cable, C is the tensile elastic modulus of the stay cable, and k is the elastic coefficient of the spring. The formula can be obtained by calculating by combining Newton's second law:
the equation is a one-dimensional wave equation, can be solved by a separation variable equation, and can be obtained by being brought into a B cable 1 stress simplified model shown in figure 10:
according to experimental data testing and mechanical analysis calculation, when the size L of the opening of the layered control cable tie at the x position is equal to 0.3 time of the displacement Y (x, t) of the section at the x position, the distribution of the whole force model of the cable is uniform. Therefore, a design formula of the opening size L of the layered control type cable tie is deduced:
when the x arrangement layered control ribbon 8 is selected, the position with the largest displacement of the cross section of the stay cable is generally selected, and the time when the glass rises to the topmost point and the time when the glass falls to the lowest point are generally calculated respectively when t is selected.
The structure of the layered control ribbon 2 comprises a joint 201 clamped with a sheet metal, a limiting ring 202 of a B cable is arranged above the joint, and the limiting ring 202 is a limiting ring 203 of a C cable.
According to the invention, the door metal plate 7, the B stay cable 1 and the C stay cable 3 are arranged in a layered manner, so that the mutual interference among the door metal plate 7, the B stay cable 1 and the C stay cable 3 is solved, the mutual collision is caused to generate abnormal sound under the condition of receiving complex vibration and force, and the satisfaction degree of customers is improved.
Because 3 both ends of C cable do not have the spring, can not carry out the bending repeatedly, tensile motion mainly produces the vibration after receiving the power of door transmission, has added the restraint in the middle of the cable after 2 interference fit with layered control ribbon, has reduced vibration range, very big solution because the abnormal sound problem that 3 vibrations of C cable produced.
Because the B cable 1 is subjected to the action of the spring 5, the bending and stretching movement is repeatedly carried out, if the B cable 1 and the layering control ribbon 2 are in interference fit in the layering control, which is equivalent to that the B cable is added with constraint in the middle position, although part of vibration can be reduced. However, in the experiment, under the action of the spring, the stress length of the sleeve is shortened, the stress at two ends of the sleeve in the B stay cable 1 is enhanced, and the damage of the sleeve is accelerated. Consequently B cable 1 adopts clearance fit with layering control ribbon 2, but if B cable 1 is too big with the clearance fit size of layering control ribbon 2 promptly layering control ribbon opening size L, can not restrict B cable 1 and carry out the bending repeatedly, and the too big cracked problem of frictional force in the middle of the too big damage of sleeve pipe both ends atress and the B cable 1 in the unable solution of B cable 1 in the range of tensile motion. Thus, hierarchical control of the strap opening size L is an important parameter for ensuring durability of the window lifter system.
After the layered control ribbon 2 is added into the glass lifter system through calculation, a sleeve stress model in the stay cable is optimized, the stress of the sleeve is not concentrated at two ends of the sleeve, the bending moment distributed in the whole is shown in figure 6, the sleeve is kept intact after the glass lifter is durable, and the service life of the glass lifter is prolonged; the friction force model of the steel wire rope in the inhaul cable is optimized, the friction force of the steel wire rope is not concentrated in the middle of the steel wire rope and is distributed in the whole body as shown in figure 7, the steel wire rope is kept in good condition after the inhaul cable is durable, and the service life of the glass lifter is prolonged.
