A vehicle window glass lifting system, including a lifting system that drives the vehicle window glass to rise or fall, an anti-pinch system that prevents the vehicle window glass from pinching people during the lifting process, and a central controller that controls both;

The lifting system includes a plurality of lifting branches and oil branches that use hydraulic cylinders to correspondingly drive each window glass up and down, and each of the lifting branches communicates with the oil branch to form an oil circulation Lifting loop, the lifting branch includes a three-position four-way solenoid valve connected in sequence, the lower chamber of the hydraulic cylinder, the upper chamber of the hydraulic cylinder, the three-position four-way solenoid valve, the hydraulic pressure The branch circuit includes a sequentially connected oil tank and an oil pump driven by a motor. The three-position four-way solenoid valve is respectively connected to the oil tank and the oil pump. The lifting loop is switched through the three-position four-way solenoid valve. The direction of the oil flow to form a lifting loop driving the window glass to rise or a falling loop to drive the glass down. Each of the lifting loops is correspondingly provided with a plurality of lifting switches. When each of the lifting switches is triggered, The lifting loop corresponding to the lifting switch starts to work to control the corresponding window glass to rise or fall;

The motor, lift switch, and three-position four-way solenoid valve are all connected to the central controller; the anti-pinch system communicates the lift loop with the fuel tank through a one-way valve and an unloading valve, and the anti-pinch system The system also includes a pressure sensor for monitoring the hydraulic pressure in the lifting loop and a position sensor for monitoring glass displacement. Both the pressure sensor and the position sensor are connected to the central controller with the pre-stored oil anti-pinch force setting value. The pressure sensor will The collected pressure value is transmitted to the central controller, and the position sensor transmits the collected position information to the central controller, and the central controller controls the lifting system and the anti-pinch system according to the pressure value and position information.

However, the circuit structure of the above technology is relatively complicated and the cost is high, which is not conducive to quantitative production and installation.

Contents of the invention

The technical problem to be solved by the utility model is to provide a car window one-button lifting control system which has a simple circuit structure and can realize one-key lifting of the car window. In order to achieve the above object, the technical solution adopted in the utility model is:

A one-button lifting control system for a vehicle window, the control system includes a hydraulic cylinder connected to a single vehicle window, a control valve connected in parallel with the hydraulic cylinder, and each hydraulic cylinder is connected in parallel; the control valve is connected with a first oil tank and The second oil tank, a hydraulic motor and a hydraulic pump are also arranged between the first oil tank and the control valve; the control valve can be a three-position valve.

When the one-key up button is pressed, all hydraulic cylinders work, the motor rotates forward, and the hydraulic pump is driven to work, and all windows are raised with one key; when the one-key down button is pressed, all hydraulic cylinders work, the motor reverses, and the hydraulic pump is driven work, to realize one-key down of all car windows.

On the basis of adopting the above technical scheme, the utility model can also adopt the following further schemes:

The hydraulic cylinder is also connected in parallel with an oil tank, and two check valves are also arranged on the circuit connection between the oil tank and the hydraulic cylinder.

A fluid regulator is also provided between the first oil tank and the hydraulic pump.

The hydraulic motor is a one-way electric motor, the hydraulic pump is a one-way hydraulic pump, the hydraulic cylinder is a single-piston rod cylinder, and the first oil tank and the second oil tank can be ventilated.

The fluid regulator may be a filter.

The three-position valve is also connected with a relay.

After adopting the technical scheme of the utility model, through the arrangement of the parallel hydraulic cylinder and the one-way valve, the motor can be operated through the one-way valve in different directions when the motor is rotating forward or reversely. At the same time, the circuit composition of this system is simple, and it has the function of safety protection while controlling the one-key lifting of the window, which is safe and efficient.
