Description

Technical Field

[0001] The present invention belongs to the technical field of vehicle passenger door control, and in particular relates to a one-button opening system for a passenger door and a vehicle. Background Art

[0002] The statements in this section merely provide background information related to the present invention and do not necessarily constitute prior art.

[0003] While public transportation brings convenience to people's lives and work, the accompanying traffic accidents pose a serious threat to their lives and property, leading to a growing emphasis on traffic safety. Currently, passenger door switches on buses mostly utilize pneumatic control principles. The door opening control principle involves the vehicle's air supply passing through the instrument panel valve, internal and external emergency valves, and then entering a two-position, five-way solenoid valve. This air is then distributed through the two-position, five-way valve by controlling a rocker switch on the instrument panel, and then enters one end of the cylinder. The cylinder, which serves as the passenger door's actuating mechanism, consists of two chambers. Controlling the intake and exhaust of these chambers allows the passenger door to open and close.

[0004] Because the passenger door is powered by the air provided by the vehicle's air tank, in an emergency, the only way to open the passenger door is by using a rocker switch or an emergency valve. The rocker switch relies on the vehicle's electrical power and will be unusable in the event of a power failure. The emergency valve only provides an exhaust function, which takes 6 to 10 seconds and must be opened manually after exhaust is complete. The front and rear doors must be deflated separately, and there is no linkage. In an emergency, it is difficult for non-professionals to accurately and quickly open the lifeline. Therefore, the urgent problem at this stage is to ensure that all doors can still be opened to the emergency width in extreme cases after the vehicle loses power or air. Summary of the Invention

[0005] In order to overcome the deficiencies of the above-mentioned prior art, the present invention provides a one-button opening system for passenger doors and a vehicle. By setting a spare air tank and a push-pull valve on the spare air circuit, all doors can be opened to an emergency width through the push-pull valve when the power or air of the entire vehicle is cut off. The system is easy to operate and the doors can be opened quickly, which greatly improves the safety performance of the entire vehicle.

[0006] To achieve the above objectives, one or more embodiments of the present invention provide the following technical solutions: A one-touch opening system for a passenger door, comprising: a main air circuit, a backup air circuit, and a main air source and a driving air cylinder connected to the main air circuit and the backup air circuit, respectively;

[0007] The backup air circuit is provided with a backup air reservoir and a push-pull valve, and the backup air reservoir is connected to the driving cylinder air circuit by controlling the push-pull valve, and the driving cylinder controls the state of the passenger door.

[0008] Furthermore, a first one-way valve is provided on the connecting air path between the main air source and the backup air cylinder.

[0009] Furthermore, a spare gas circuit low pressure sensor is provided on the gas circuit connecting the spare gas cylinder and the push-pull valve.

[0010] Furthermore, a spare gas circuit oil-water separator and a shielding valve are sequentially arranged along the gas circuit direction behind the push-pull valve.

[0011] Furthermore, after passing through the shielding valve, it is divided into a first branch air path and a second branch air path. The first branch air path is connected to the air inlet end of the first two-position five-way solenoid valve after passing through the three-way valve, and the second branch air path is directly connected to the pilot head of the first two-position five-way solenoid valve.

[0012] Furthermore, the main gas path is connected to the first two-position five-way solenoid valve gas path through the three-way valve.

[0013] Furthermore, the first two-position five-way solenoid valve controls the driving cylinder, thereby enabling the passenger door to be opened.

[0014] Furthermore, the shielding valve is used to shield the push-pull valve.

[0015] Furthermore, the main gas line is sequentially provided with an instrument panel valve, an external emergency valve, an internal emergency valve, a main gas line oil-water separator, a suppression valve assembly, a main gas line low-pressure sensor, and a buffer valve along the gas line direction.

[0016] A second aspect of the present invention provides a vehicle that adopts the above-mentioned one-touch opening system for a passenger door.

[0017] One or more of the above technical solutions have the following beneficial effects:

[0018] In the present invention, by providing a spare air tank and a push-pull valve on the spare air circuit, all vehicle doors can be opened to an emergency width through the push-pull valve when the power or air of the vehicle is cut off. The operation is convenient and the doors can be opened quickly, which greatly improves the safety performance of the vehicle.

[0023] It should be noted that the following detailed descriptions are exemplary and intended to provide further explanation of the present invention. Unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which the present invention belongs.

[0024] It should be noted that the terms used herein are for describing particular embodiments only and are not intended to limit the exemplary embodiments according to the present invention.

[0025] In the absence of conflict, the embodiments of the present invention and the features thereof may be combined with each other.

[0026] Example 1

[0027] like Figure 1 As shown, this embodiment discloses a one-touch opening system for a passenger door, comprising: a main air circuit, a backup air circuit, and a main air source and a driving cylinder connected to the main air circuit and the backup air circuit respectively;

[0028] The backup air circuit is provided with a backup air reservoir and a push-pull valve, and the backup air reservoir is connected to the driving cylinder air circuit by controlling the push-pull valve, and the driving cylinder controls the state of the passenger door.

[0029] In this embodiment, the main air line from the main air source 1 to the driving cylinder 17 is sequentially provided with an instrument panel valve 2, an external emergency valve 3, an internal emergency valve 4, a main air line oil-water separator 5, a suppression valve assembly 6, a main air line low-pressure sensor 7, a buffer valve 8, a three-way valve 15, and the first two-position five-way solenoid valve 16.

[0030] During normal use, the main air source 1 enters the external emergency valve 3 and the internal emergency valve 4 through the instrument panel valve 2, and is filtered through the oil-water separator 5, and enters the first two-position five-way solenoid valve 16 through the passage end of the suppression valve assembly 6, the main air circuit low-pressure sensor 7 and the buffer valve 8. The first two-position five-way valve 16 is switched by the rocker switch on the driver's side of the instrument panel to realize the normal opening and closing of the passenger door.

[0031] In this embodiment, the suppression valve assembly 6 is a combination of a second two-position three-way valve and a second one-way valve, which can shield the main air circuit external emergency valve 3 and the internal emergency valve 4 during driving.

[0032] Specifically, the suppression valve assembly 6 includes two passages, one for normal intake and exhaust, and one for one-way air passage, only in, when the vehicle speed is greater than 5km / h, the suppression valve assembly 6 receives an electrical signal, the internal valve core is reversed, at this time the air passage is one-way, the emergency valve cannot exhaust, and shielding is achieved. When the vehicle speed is reduced to below 5km / h, the suppression valve assembly 6 is powered off, the valve core is reset, and the emergency valve enters a working state.

[0033] In this embodiment, a first one-way valve 9, a standby air cylinder 10, a standby air path low pressure sensor 11, a push-pull valve 12, a standby air path oil-water separator 13 and a shielding valve 14 are sequentially arranged on the standby air path from the main air source to the driving air cylinder 17. The air path from the shielding valve 14 to the driving air cylinder is divided into a first branch air path and a second branch air path. The first branch air path is connected with the air inlet path of the first two-position five-way electromagnetic valve 16 after passing through the three-way valve 15. The second branch air path is directly connected with the pilot head air path of the first two-position five-way electromagnetic valve 16.

[0034] As can be understood, the two-position five-way valve has one air inlet, two air outlets, two exhaust ports and one pilot head, and the pilot head is a pneumatic control valve core reversing air inlet. Among them, the three-way valve 15 is connected with the air inlet of the first two-position five-way electromagnetic valve 16, the two air outlets of the first two-position five-way electromagnetic valve 16 are respectively connected with the two ends of the driving air cylinder 17, and the pilot head of the first two-position five-way electromagnetic valve 16 is connected with the second branch air path.

[0035] As can be understood, the passenger car has two doors, and each door is provided with a driving air cylinder 17. The first air outlet of the first two-position five-way electromagnetic valve 16 is connected with the three-way valve through a pipeline, and after passing through the three-way valve, it is divided into two paths and connected with the door opening end air ports of the two driving air cylinders 17 respectively. Similarly, the second air outlet of the first two-position five-way electromagnetic valve 16 is connected with the three-way valve through a pipeline, and after passing through the three-way valve, it is divided into two paths and connected with the door closing end air ports of the driving air cylinder 17 respectively.

[0036] In this embodiment, the shielding valve 14 is a two-position three-way valve, which realizes shielding of the standby air path push-pull valve 12 during driving, and improves driving safety.

[0037] Similarly, the shielding valve 14 receives the same electrical signal as the suppression valve assembly 6. When the vehicle speed is greater than 5km / h, the shielding valve 14 is reversed, and the air path is cut off. At this time, the push-pull valve 12 on the standby air path is shielded and cannot work.

[0038] The backup air reservoir 10 is connected to the air inlet of the push-pull valve 12 via a backup air line low-pressure sensor 11. This sensor provides a fault signal via an instrument in the event of an incidental failure of the backup air reservoir 10. Because the backup air line is rarely used, and to prevent untimely repairs that could lead to a loss of safety features, a backup air line low-pressure sensor 11 is added to monitor the backup air line in real time to ensure normal operation.

[0039] The provision of the first one-way valve 9 can ensure that when the vehicle's air reservoir fails or runs out of gas, the spare air reservoir 10 can maintain air pressure without leaking.

[0040] In this embodiment, the main air source 1 is a continuous one-way air supply from the backup air cylinder 10. When the power supply of the entire vehicle is damaged and the main air source is lost, and the passenger door needs to be opened urgently, the push-pull valve 12 can be unlocked and activated. The gas stored in the backup air cylinder 9 can be divided into two paths at the same time through the push-pull valve 12 after passing through the backup air circuit oil-water separator 13 and the shielding valve 14. The second branch air path enters the pilot head of the first two-position five-way solenoid valve 16, so that the first two-position five-way solenoid valve 16 enters the door-opening state. The first branch air path enters the air inlet end of the first two-position five-way solenoid valve 16 through the three-way valve 15. At this time, the first two-position five-way solenoid valve 16 is in the door-opening state, and can enter the driving cylinder through the air inlet end of the first two-position five-way solenoid valve 16, and the passenger door is opened and maintained in the open state.

[0041] The pilot head is the air inlet for the pneumatically controlled valve core's reversal. When the second branch air path enters the pilot head, the gas squeezes the valve core, causing the valve core to reverse direction. The air inlet of the first two-position five-way solenoid valve 16 is connected to the air port at the door-opening end of the drive cylinder 17. At this time, the gas from the first branch air path enters the air inlet of the first two-position five-way solenoid valve 16 after passing through the three-way valve 15. Then, it enters the air port at the door-opening end of the drive cylinder 17, driving the piston in the drive cylinder 17 to move, realizing the door opening action. Because the entire vehicle is in an emergency state with no power at this time, the first two-position five-way solenoid valve 16 cannot be electrically reversed. Regardless of operation, the existing door open state can only be maintained.

[0042] Specifically, the first branch air circuit is connected to the first air inlet of three-way valve 15, the main air circuit is connected to the second air inlet of three-way valve 15, and the air outlet of three-way valve 15 is connected to the air inlet of the first two-position five-way solenoid valve 16. Three-way valve 15 is a one-way air circuit, that is, when air is entering, the first and second air inlets are connected to the air outlet respectively. However, the first and second air inlets are different from each other. However, the backup air circuit is isolated from the main air circuit, and they are not affected by each other, ensuring the normal operation of the main air circuit of the passenger door. The backup air circuit exists independently of the original emergency air circuit and is not affected by the emergency valve.

[0043] The push-pull valve 12 is an operating button for the backup gas circuit. It adopts a self-locking and covered structure to prevent accidental start-up during normal operation. It can automatically maintain the emergency state after emergency operation and can be manually released after the emergency is over. It can be reused. The push-pull valve 12 can be selected from existing push-pull valves according to needs.
