Problems solved by technology

In order to protect the passengers near the passenger door from being pinched, lower air pressure is used to ensure the slow opening and closing of the door. Therefore, when the bus is running at high speed, the driving force for keeping the door closed is weak. When an external force is applied, it may be opened, causing nearby passengers to fall out of the car, posing a serious safety hazard

Embodiment 1

[0026] like figure 1 As shown, this embodiment provides a pneumatic swing door system applied to automobiles, including the following structure.

[0027] The air source is used to provide the compressed air that enters the door pump 6.

[0028] Tee joint 2, the first interface of tee joint 2 (i.e. air source interface 1, such as figure 1 marked in the middle) to the air supply.

[0029] The first pressure regulating filter 3 , the air inlet of the first pressure regulating filter 3 is connected with the second interface of the tee joint 2 . The model of the first pressure regulating filter 3 is GR20006LF1.

[0030] The first two-position three-way solenoid valve 4, the first air inlet of the first two-position three-way solenoid valve 4 is connected to the third interface of the three-way joint 2, the second air intake of the first two-position three-way solenoid valve 4 The port is connected with the air outlet of the first pressure regulating filter 3.

[0031] Warburk ...

Embodiment 2

[0053] This embodiment provides a pneumatic swing door 7 system, which is applied to automobiles. The difference between the gas path of this embodiment and Embodiment 1 is that the second two-position three-way solenoid valve is used to replace the Warburk valve 5, and the gas outlet of the first two-position three-way solenoid valve 4 is connected to the second two-position three-way solenoid valve. The air inlet of the valve is connected, the first air outlet of the second two-position three-way solenoid valve is connected with the first air chamber 62 , and the second air outlet of the second two-position three-way solenoid valve is connected with the second air chamber 63 .

[0054] Therefore, it is necessary to additionally provide an exhaust gas path of the first gas chamber 62 , and the gas path communicates with the outside for exhausting the gas inside the first gas chamber 62 . A first electromagnetic valve is arranged on the air circuit.

[0055] And it is necessa...

Embodiment 3

[0062] This embodiment provides an automobile, including the pneumatic swing door 7 system in Embodiment 1, and the swing door 7 is installed at the front and rear doors of the automobile.

[0063] Using the pneumatic swing door system in Embodiment 1, the swing door 7 can be opened and closed in the low pressure mode to avoid pinching the passengers near the swing door 7. When the speed of the car reaches 5km / h, switch to the high pressure mode and press the swing door tightly. 7. Avoid the accidental opening of the swing door 7 and cause safety accidents, and improve the safety of the car.

[0064] Present embodiment also comprises driver's seat, speed reducer and air horn, and pneumatic swing door system also comprises the second pressure regulating filter 9 and four-point air outlet valve 10, the air inlet of the second pressure regulating filter 9 (i.e. air source interface) 1, such as Figure 4 middle mark) is connected to the air source, the air outlet of the second pr...

Abstract

The invention discloses a pneumatic swing door system and an automobile. The pneumatic swing door system comprises a gas source, a three-way joint, a first pressure adjusting filter, a first two-position and three-way solenoid valve, a door pump, a swing door and a control mechanism, wherein the three-way joint is connected with the gas source; the first pressure adjusting filter is connected withthe three-way joint; the first two-position and three-way solenoid valve is connected with the three-way joint, and is connected with the first pressure adjusting filter; the door pump comprises a gas chamber and a piston, the gas chamber is divided into a first gas chamber and a second gas chamber by the piston, and the first gas chamber is connected with the first two-position and three-way solenoid valve; the swing door is connected with the piston; and the control mechanism is electrically connected with the first two-position and three-way solenoid valve. According to the pneumatic swingdoor system, low-pressure driving is adopted when the swing door is opened and closed, after the speed of the automobile reaches the predetermined value, the swing door is pressurized, so that the swing door is closed more tightly, and the safety of passengers is ensured.

Description

technical field [0001] The invention relates to the field of automobile doors, in particular to a pneumatic swing door system and an automobile. Background technique [0002] Most of the passenger doors used by passenger cars on the market are opened and closed by pneumatic drive. Compressed air is injected into the air chamber of the door pump, and the door is driven by the piston. In order to protect the passengers near the passenger door from being pinched, lower air pressure is used to ensure the slow opening and closing of the door. Therefore, when the bus is running at high speed, the driving force for keeping the door closed is weak. When an external force is applied, it may be opened, causing nearby passengers to fall out of the car, which poses a serious safety hazard. Contents of the invention [0003] The purpose of the present invention is to address the deficiencies in the prior art, and propose a pneumatic swing door system and a car. The swing door is opene...
