Problems solved by technology

[0002] Vehicles are means of transportation used by people. When the vehicle is in use, the driver is generally required to pull the parking brake and then open the door to get off the vehicle. The Chinese authorized announcement number is CN203819220U utility model patent specification discloses a parking brake for a trailer used in coal mines The system includes fuel tank 1, filter 2, hydraulic pump 3, safety valve 4, tractor parking brake valve 5, tractor parking hydraulic cylinder 6, and tractor parking brake 7. By pulling the tractor parking brake valve 5, the traction The vehicle parking hydraulic cylinder 6 acts to realize the braking of the tractor's parking brake 7, but in practice, it often happens that people do not pull the tractor's parking brake valve 5 when they open the door and get off the vehicle, so that the vehicle does not have a parking brake. safety accidents on the road

Embodiment 1

[0014] A vehicle door opening parking brake control device, including a hydraulic pump 1, a fuel tank 5, a parking hydraulic cylinder 6, a parking brake 7, a parking brake valve 10, a filter 11 and a safety valve 12, and the parking brake 7 includes a moving plate 7-1 And the static plate 7-2, the hydraulic pump 1 is connected to the power take-off port of the gearbox of the vehicle, the oil inlet of the hydraulic pump 1 is connected to the oil tank 5 through the filter 11, the piston rod 6- of the parking hydraulic cylinder 6- 1 is connected with the moving plate 7-1 of the parking brake 7;

[0015] It also includes a push rod roller valve 2, an electromagnetic reversing valve 3, an air bag 4, a power supply 8 and an air control switch 9. The push rod 2-1 of the push rod roller valve 2 is connected to the door 100 of the vehicle, and the push rod roller valve 2 The air inlet port P of the air bag is connected with the air bag 4, the executive port A port of the ejector roller...

Embodiment 2

[0019] The difference between embodiment 2 and embodiment 1 is: the power supply 8 and air control switch 9 in embodiment 1 are changed to pressure sensor 14 and main controller 15, and the execution port A of the ejector pin roller valve 2 is connected to the pressure sensor The air control port A port of 14 is connected, the electrical signal output end of the pressure sensor 14 is connected with the main controller 15, and the main controller 15 is connected with the wiring terminal of the electromagnetic reversing valve 3.

[0020] The vehicle door-opening parking brake control device can be connected with an alarm, etc., so it has many functions.

[0021] The working process of embodiment 1 is as follows: when the driver starts the vehicle, the engine works and drives the hydraulic pump 1 to work. After the driver closes the door, the ejector rod 2-1 of the ejector rod roller valve 2 retracts, and the ejector rod roller valve 2 retracts. The air inlet P is connected with ...
