A window lift system

Abstract

The invention relates to a vehicle window glass lifting system. The vehicle window glass lifting system comprises a lifting system body, a pinch prevention system and a central controller. The lifting system body comprises lifting branches and oil liquid branches. All the lifting branches are communicated with the oil liquid branches. Lifting loops switch the flow direction of oil liquid in a pipeline through three-position four-way solenoid valves to form ascending loops or descending loops. Each lifting loop is provided with a lifting switch. When all the lifting switches are triggered, the lifting loops corresponding to the lifting switches start to work. Motors, the switches and the three-position four-way solenoid valves are all connected with the central controller. The pinch prevention system enables the lifting loops to be communicated with an oil tank through check valves and unloading valves. The pinch prevention system further comprises pressure sensors and position sensors, wherein the pressure sensors are used for monitoring hydraulic pressure in the lifting loops, the position sensors are used for monitoring displacement of glass, and the pressure sensors and the position sensors are all connected with the central controller. The central controller controls the lifting system body and the pinch prevention system according to the value of pressure and position information.

Description

technical field [0001] The invention relates to a vehicle window glass lifting system. Background technique [0002] With the popularization of vehicles, more and more children have more and more opportunities to touch cars. Because children are active by nature, they often touch the window switch when they stay in the car. When adults do not pay attention to children , the danger arises at this moment. When children operate the window glass to rise, their limbs tend to stick out of the window. At this time, when the window glass lift switch is turned, the car window glass continues to rise. Children or adults are prone to panic when they find it. The first reaction may be to keep shaking, trying to pull out the trapped limb in time. At this time, it is easy to pinch the limb of the child and even cause the victim to suffocate (often happens to children). With the development of modern automobiles, the old hand-operated windows almost no longer appear, and electric windows ...

AI Technical Summary

Problems solved by technology

[0003] 1. In the current electric window lifting system, after the motor loses power, the window glass can only maintain the position when the power was lost, and it is almost impossible to lift it. Once the victim is trapped, it is difficult to get out of the trap. If the victim panics and keeps shaking, If you want to get out of the situation of being trapped, it will often cause more harm. If a child is trapped and the adult does not find out in time, the harm will be even greater;

[0004] 2. Some vehicle window glass has automatic anti-pinch function, but the anti-pinch force set by various manufacturers has not formed a unified standard. You will still be pinched, and even cause more serious consequences;

[0005] 3. Even if some vehicles have the automatic anti-pinch function of the windows, the car manufacturers consider the cost and layout, and only a few windows have this function. Most of the four windows of the car models are not equipped with the automatic anti-pinch function. Therefore, other windows that are not equipped with automatic anti-pinch function are likely to cause injury to people inside and outside the car;

[0006] 4. Some vehicles do not have an automatic anti-pinch function. When the system is working normally, whether it is misoperation or when the glass is raised, the limbs of people inside and outside the vehicle are too late to withdraw, which will cause the victim's limbs to be squeezed and injured by the window, or even cause more serious injuries. as a result of
