Description
Technical Field
The application belongs to the technical field of emergency opening and closing devices of vehicle doors, and mainly relates to a quick-opening emergency valve, a quick-opening emergency valve and a corresponding emergency control system of the vehicle door.
Background
Large and medium-sized buses are common transportation means in daily life, and the safety performance of the buses is related to public safety of the public. Recently, with the improvement of the overall safety awareness of the society, people also put higher requirements on safety related to the public field, and large and medium buses are no exception.
The door of the existing large and medium-sized passenger car is mostly pneumatically opened and closed, and a driver can control the forward or backward movement of the door opening and closing cylinder by controlling a rocker switch on a driving platform, so that the opening and closing of the door of the passenger car are realized. However, when the passenger car encounters an emergency (such as car accident, circuit damage or failure of rocker switch, etc.), it is difficult to open the car door in the original manner. If the door is not opened at a late stage, passengers are evacuated rapidly or outside rescue personnel can open the door rapidly from outside the car, and rescue wounded persons cannot talk. For this purpose, an emergency valve switch is required to be installed on the vehicle, so that it has a function of opening the door in an emergency state. Obviously, the speed of emergency opening is a very important indicator for emergency valve opening and closing.
The existing common quick-opening emergency valve for the vehicle door is generally arranged above the vehicle door or on the vehicle body outside the vehicle door and is connected with the opening and closing air passage of the vehicle door. When an emergency state occurs, the knob on the emergency valve is turned to enable the air cylinder to be disconnected, and after the air in the air cylinder is exhausted, the automobile door is broken by manpower. In this working mode, the speed of emergency door opening depends on the speed of cylinder exhaust and is related to manpower, and the effect of emergency door opening is not ideal.
Disclosure of Invention
The application aims at: in order to further improve the speed of the door quick-opening emergency valve for opening the door in an emergency state, the novel door quick-opening emergency valve, a switch and a corresponding quick-opening emergency control system are provided.
Specifically, the application is realized by adopting the following technical scheme: the valve body comprises a valve core disc and a valve core shaft penetrating through the center of the valve core disc, the valve body is connected at the lower end of the valve core shaft and is coaxially and rotatably connected with the valve core disc, the valve core disc is provided with a valve core disc matching surface matched with the valve body, 4 air holes are distributed on the valve core disc matching surface, namely a first valve core disc air hole, a second valve core disc air hole, a third valve core disc air hole and a fourth valve core disc air hole, wherein the first valve core disc air hole, the second valve core disc air hole and the fourth valve core disc air hole are distributed on the circumference of a circle taking the center of the valve core disc as the center of the circle, the second valve core disc air hole, the fourth valve core disc air hole and the center of the valve core disc are distributed on the other straight line, and the two straight lines are in vertical relation; two air passages are arranged in the valve core disc, wherein one air passage enables the air holes of the first valve core disc surface to be communicated with the air holes of the fourth valve core disc surface, and the other air passage enables the air holes of the second valve core disc surface to be communicated with the air holes of the third valve core disc surface; the valve body is provided with a valve body matching surface matched with the valve core disc, 4 air holes are distributed on the valve body matching surface, namely a first valve body surface air hole, a second valve body surface air hole, a third valve body surface air hole and a fourth valve body surface air hole, wherein the position of the first valve body surface air hole is matched with the position of the first valve core disc surface air hole on the valve core disc matching surface, the position of the second valve body surface air hole is matched with the position of the second valve core disc surface air hole on the valve core disc matching surface, the position of the third valve body surface air hole is matched with the position of the third valve core disc surface air hole on the valve core disc matching surface, and the position of the fourth valve body surface air hole is matched with the position of the fourth valve core disc surface air hole on the valve core disc matching surface; the valve body is also provided with an air inlet, a normal air outlet, an emergency air outlet and an air outlet, 4 air channels are arranged in the valve body, wherein the air inlet is communicated with the first valve body surface air hole through a first air channel in the valve body, the normal air outlet is communicated with the second valve body surface air hole through a second air channel in the valve body, the air outlet is communicated with the third valve body surface air hole through a third air channel in the valve body, and the emergency air outlet is communicated with the fourth valve body surface air hole through a fourth air channel in the valve body.
The gas path structure of the quick-opening emergency valve formed by the technical scheme is as follows: because the position of the first valve body surface air hole on the valve body matching surface is matched with the position of the first valve body surface air hole on the valve core disc matching surface, and the position of the fourth valve body surface air hole on the valve body matching surface is also matched with the position of the fourth valve core surface air hole on the valve core disc matching surface, the first valve body surface air hole on the valve body matching surface is communicated with the air inlet of the valve body, and the fourth valve body surface air hole on the valve body matching surface is communicated with the emergency air outlet of the valve body, a smooth air path (namely the air inlet of the valve body to the emergency air outlet of the valve body) is formed from the air inlet of the valve body to the first valve body surface air hole, the first valve core surface air hole, the fourth valve body surface air hole and the emergency air outlet of the valve body in sequence. Similarly, a smooth air path (namely, the normal air outlet of the valve body to the air outlet of the valve body) is formed from the normal air outlet of the valve body to the second valve body surface air hole, the second valve core surface air hole, the third valve body surface air hole and the air outlet of the valve body in sequence. Therefore, two smooth air paths are formed between the valve core disc and the valve body due to the matching of corresponding air holes.
When the valve core disc rotates correspondingly (the valve body is not moved when the valve core disc rotates), the first valve core disc surface air hole on the valve core disc matching surface rotates correspondingly to the position where the original second valve core disc surface air hole is located (according to the position relation of 4 air holes on the valve core disc matching surface, when the valve core disc rotates 90 degrees, the first valve core disc surface air hole can rotate to the position where the original second valve core disc surface air hole is located), the fourth valve core disc surface air hole on the valve core disc matching surface also rotates to the position where the original first valve core disc surface air hole is located, at the moment, the matching relation of the valve core disc and the air hole on the valve body is changed into the matching relation of the first valve core disc surface air hole and the second valve body surface air hole, and the fourth valve core disc surface air hole and the first valve body surface air hole are matched, so that an air path from the air inlet of the valve body to the first valve body surface air hole, the fourth valve core disc surface air hole, the first valve body surface air hole and the normal air outlet of the valve body (namely the air inlet of the valve body to the normal air outlet of the valve body) is formed. As for the second valve disc face air hole and the third valve disc face air hole on the valve disc matching face, the second valve disc face air hole and the third valve disc face air hole can rotate in the rotating process, but because the third valve disc face air hole is not located on the same circumference of other valve disc matching face air holes (corresponding to the third valve disc face air hole is not located on the same circumference of other valve body matching face air holes), the third valve disc face air hole is located nearby the original fourth valve disc face air hole after rotation, but is not located on the original fourth valve disc face air hole, and therefore the third valve disc face air hole cannot be matched with the fourth valve body face air hole, and at the moment, the fourth valve body face air hole is covered by a place without air holes on the valve disc matching face. Correspondingly, the air hole on the surface of the second valve core disk cannot be matched with the air hole on the surface of the third valve body, and the air hole on the surface of the third valve body is covered by the place without the air hole on the matching surface of the valve core disk. At this time, only one smooth air path from the air inlet of the valve body to the normal air outlet of the valve body exists between the valve core disc and the valve body, and the air outlet and the emergency air outlet of the valve body cannot be ventilated because the third valve body surface air hole and the fourth valve body surface air hole are covered by the valve core disc.
In the above technical scheme, the distance from the air hole of the third valve disk surface to the center of the valve disk on the matching surface of the valve disk may be smaller than the distance from the air hole of the first valve disk surface to the center of the valve disk, or may be larger than the distance from the air hole of the first valve disk surface to the center of the valve disk.
For convenient processing, the valve core disc and the valve core shaft can be supported by adopting integrated forming, and the valve core disc and the valve core shaft are simple in structure and easy to assemble.
In order to conveniently discharge the residual air of the air path when the emergency working state is restored to the normal working state, an exhaust hole is further formed in the matching surface of the valve core disc, the exhaust hole is positioned near the air hole of the third valve core disc, the exhaust hole is distributed on the same straight line with the air hole of the first valve core disc, the air hole of the third valve core disc and the center of the valve core disc, and the exhaust hole is distributed on the same circumference taking the center of the valve core disc as the center of the circle.
The automobile door quick-opening emergency valve switch corresponding to the quick-opening emergency valve comprises a knob, a valve seat and a valve cover, and further comprises the automobile door quick-opening emergency valve, wherein a valve body of the automobile door quick-opening emergency valve is positioned at the bottom of the valve seat, a valve core is positioned in an inner cavity of the valve seat, the valve cover is connected to the top of the valve seat, and the knob is connected to a valve core shaft at the top of the valve core.
In order to ensure that the valve core disc rotates in place when emergency operation is implemented, a limiting mechanism is arranged at the upper end of the valve core disc to prevent the valve core disc from rotating to other positions by mistake.
The vehicle door emergency control system matched with the quick-opening emergency valve switch comprises a cylinder, an air source, a vehicle door control valve, a three-way valve and the vehicle door quick-opening emergency valve switch, wherein the vehicle door control valve comprises an air inlet, two air outlets and air outlets matched with the two air outlets respectively; the three-way valve comprises a three-way valve first air port, a three-way valve second air port and a three-way valve third air port, wherein: when the third air port of the three-way valve supplies air, the second air port of the three-way valve is communicated with the third air port of the three-way valve, and meanwhile, the first air port of the three-way valve is closed with the second air port of the three-way valve; when the third air port of the three-way valve is not supplied with air, the second air port of the three-way valve is in a closed state with the third air port of the three-way valve, and meanwhile, the first air port of the three-way valve is in a communicating state with the second air port of the three-way valve; the cylinder is provided with a piston rod, a door opening port and a door closing port, the piston rod is connected with a door opening and closing mechanism of the vehicle door, the piston rod drives the door opening and closing mechanism to open the vehicle door when the door opening is in air inlet, and the piston rod drives the door opening and closing mechanism to close the vehicle door when the door opening is in air inlet; the output end of the air source is connected with the air inlet of the valve body in the door quick-opening emergency valve switch, the air inlet of the door control valve is connected with the normal air outlet of the valve body in the door quick-opening emergency valve switch, one air outlet of the door control valve is connected with the air inlet of the door closing end of the air cylinder, the other air outlet is connected with the first air inlet of the three-way valve, the second air inlet of the three-way valve is connected with the air inlet of the door opening end of the air cylinder, and the third air inlet of the three-way valve is connected with the emergency air outlet of the valve body in the door quick-opening emergency valve switch.
According to the foregoing description, the quick-opening emergency valve has two air path structures in different rotation states, wherein the first air path structure has two air paths simultaneously, namely, an emergency air outlet from an air inlet of the valve body to an emergency air outlet of the valve body and a normal air outlet from the valve body to an air outlet of the valve body, and the second air path structure has only one air path, namely, an air inlet from the valve body to a normal air outlet of the valve body. The quick-opening emergency valve can be switched in two gas path structures by rotating a knob on a switch of the quick-opening emergency valve of the vehicle door.
Therefore, in the vehicle door emergency control system, when the quick-opening emergency valve is in the second gas path structure, namely, only one gas path exists, gas from the gas source is sequentially output to the gas inlet of the vehicle door control valve through the gas inlet of the valve body and the normal gas outlet of the valve body, meanwhile, the third gas port of the three-way valve is not supplied with gas because the emergency gas outlet of the valve body is not output, and at the moment, the working state of the three-way valve is that the first gas port of the three-way valve is communicated with the second gas port of the three-way valve, and the second gas port of the three-way valve is closed with the third gas port of the three-way valve, so that one gas outlet of the vehicle door control valve is sequentially communicated with the opening end gas port of the cylinder through the first gas port of the three-way valve and the second gas port of the three-way valve. In this state, the normal open and close of the door can be performed by switching the intake relationship between its intake port and both the exhaust ports by the door control valve.
If the door is to be closed, the air inlet relation of the door control valve can be switched from the air inlet of the door control valve to the air outlet of the door control valve connected with the air inlet of the door closing end of the air cylinder, then the air from the air source enters the air inlet of the door closing end of the air cylinder, and the residual air in the door opening end of the air cylinder reaches the other air outlet of the door control valve communicated with the air outlet through the three-way valve and is discharged through the air outlet matched with the air outlet, so that the piston rod of the air cylinder operates to enable the door opening and closing mechanism of the door to close the door.
The door opening process is exactly opposite to the process, namely, the air inlet relation of the door control valve is switched to be changed from the air inlet of the door control valve to the other air outlet of the door control valve connected with the door opening end air port of the air cylinder through the three-way valve, then the air from the air source enters the door opening end air port of the air cylinder, and the residual air in the door closing end of the air cylinder is discharged through the air outlet of the door control valve communicated with the air outlet and the air outlet matched with the air outlet, so that the piston rod of the air cylinder operates to enable the door opening and closing mechanism of the door to open the door.
When the vehicle door is closed in an emergency state, an emergency door opening is required. At this time, the knob on the door quick-opening emergency valve switch is rotated by 90 degrees, so that the emergency valve can be switched to a first gas path structure, namely a structure with two gas paths at the same time. Because of the change of the gas path, the gas from the gas source is sequentially output to the third gas port of the three-way valve through the output end of the gas source, the gas inlet of the valve body and the emergency gas outlet of the valve body. Because the third air port of the three-way valve starts to supply air, the working state of the three-way valve is changed, namely the second air port of the three-way valve is communicated with the third air port of the three-way valve, and meanwhile, the first air port of the three-way valve is closed with the second air port of the three-way valve, which means that the air from the air source is directly output to the opening end air port of the air cylinder through the third air port of the three-way valve and the second air port of the three-way valve. And simultaneously, the air port at the door closing end of the air cylinder is communicated with the air outlet of the vehicle body control valve, the air inlet of the vehicle body control valve and the normal air inlet of the valve body in sequence, so that the exhaust is started. Because the air inlet of the door opening end is used for air inlet and the air inlet of the door closing end is used for air exhaust, the piston rod drives the door opening and closing mechanism of the door to rapidly open the door, and the door is rapidly opened in an emergency state.
In the technical scheme, the vehicle door control valve is a two-position five-way electromagnetic valve.
In the above technical scheme, the three-way valve is an on-off valve.
Compared with the prior art, the application has the following beneficial effects: through the arrangement of the two gas circuit structures of the quick-opening emergency valve, the automobile door can be automatically opened by means of gas supply only by rotating the switch knob of the quick-opening emergency valve when the automobile is in an emergency state, manual intervention is not needed any more, the opening speed of the automobile door in the emergency state is greatly improved, and higher safety requirements can be met.

The positions of the distribution of the air holes are all matched with the air holes on the valve core disc matching surface 310, namely, the position of the first valve body surface air hole 401 is matched with the position of the first valve core disc surface air hole 311 on the valve core disc matching surface 310, the position of the second valve body surface air hole 402 is matched with the position of the second valve core disc surface air hole 312 on the valve core disc matching surface 310, the position of the third valve body surface air hole 403 is matched with the position of the third valve core disc surface air hole 313 on the valve core disc matching surface 310, and the position of the fourth valve body surface air hole 404 is matched with the position of the fourth valve core disc surface air hole 314 on the valve core disc matching surface 310. Thus, when the valve body 4 is connected to the lower side of the valve disc 31, the first valve body face air hole 401 can be communicated with the first valve disc face air hole 311, the second valve body face air hole 402 can be communicated with the second valve disc face air hole 312, the third valve body face air hole 403 can be communicated with the third valve disc face air hole 313, and the fourth valve body face air hole 404 can be communicated with the fourth valve disc face air hole 314.
For connection to an external air path, the valve body 4 is provided with 4 air ports, namely an air inlet 41, a normal air outlet 42, an air outlet 43 and an emergency air outlet 44. In order to connect the air port and the air hole, 4 air passages are arranged in the valve body 4, wherein the air inlet 41 is communicated with the first valve body surface air hole 401 through a first air passage in the valve body 4, the normal air outlet 42 is communicated with the second valve body surface air hole 402 through a second air passage in the valve body 4, the air outlet 43 is communicated with the third valve body surface air hole 403 through a third air passage in the valve body 4, and the emergency air outlet 44 is communicated with the fourth valve body surface air hole 404 through a fourth air passage in the valve body 4.
The gas path structure of the quick-opening emergency valve is as follows: because the position of the first valve body surface air hole 401 on the valve body matching surface 40 is matched with the position of the first valve body surface air hole 311 on the valve body disc matching surface 310, and the position of the fourth valve body surface air hole 404 on the valve body matching surface 40 is also matched with the position of the fourth valve body surface air hole 314 on the valve body disc matching surface 310, meanwhile, the first valve body surface air hole 311 on the valve body matching surface 310 is communicated with the fourth valve body surface air hole 314, the first valve body surface air hole 401 on the valve body matching surface 40 is communicated with the air inlet 41 of the valve body 4, and the fourth valve body surface air hole 404 on the valve body matching surface 40 is communicated with the emergency air outlet 44 of the valve body 4, so that a smooth air path (namely, the air inlet 41 of the valve body 4 to the emergency air outlet 44 of the valve body 4) is formed from the air inlet 41 of the valve body 4 to the first valve body surface air hole 401, the first valve body surface air hole 311, the fourth valve body surface air hole 314, the fourth valve body surface air hole 404 and the emergency air outlet 44 of the valve body 4. Similarly, a clear air path is formed from the normal air outlet 42 of the valve body 4 to the second valve body surface air hole 402, the second valve core surface air hole 312, the third valve core surface air hole 313, the third valve body surface air hole 403 and the air outlet 43 of the valve body 4 (i.e. the normal air outlet 42 of the valve body 4 to the air outlet 43 of the valve body 4). It can be seen that two smooth air paths are formed between the valve core disc 31 and the valve body 4 due to the cooperation of the corresponding air holes.
When the valve disc 31 rotates correspondingly (the valve body 4 is not moved when the valve disc 31 rotates), the first valve disc surface air hole 311 on the valve disc matching surface 310 rotates correspondingly to the original position of the second valve disc surface air hole 312 (according to the position relation of 4 air holes on the valve disc matching surface 310, when the valve disc 31 rotates 90 degrees, the first valve disc surface air hole 311 can rotate to the original position of the second valve disc surface air hole 312), the fourth valve disc surface air hole 314 on the valve disc matching surface 310 also rotates to the original position of the first valve disc surface air hole 311, at this time, the matching relation of the valve disc 31 and the air holes on the valve body 4 is changed into that the first valve disc surface air hole 311 is matched with the second valve body surface air hole 402, and the fourth valve disc surface air hole 314 is matched with the first valve body surface air hole 401, so that a normal air path (that is, from the air inlet 41 of the valve body 4 to the first valve body surface air hole 401, the fourth valve disc surface air hole 314, the first valve disc surface air hole 311, the second valve body surface air hole 402 and the normal air outlet 42 of the valve body 4) is formed. As for the second valve disc surface air hole 312 and the third valve disc surface air hole 313 on the valve disc mating surface 310, the above-mentioned rotation process also causes the rotation, but since the third valve disc surface air hole 313 is not located on the same circumference of the other air holes on the valve disc mating surface 310 (corresponding to the third valve body surface air hole 403 is not located on the same circumference of the other air holes on the valve body mating surface 40), the third valve disc surface air hole 313 is located near the original position of the fourth valve disc surface air hole 314 but is not located at the original position of the fourth valve disc surface air hole 314, and therefore the third valve disc surface air hole 313 cannot be matched with the fourth valve body surface air hole 404, and at this time, the fourth valve body surface air hole 404 is covered by the position of the valve disc mating surface 310 where no air hole exists. Accordingly, the second valve disc surface air hole 312 cannot be matched with the third valve body surface air hole 403, and the third valve body surface air hole 403 is covered by the non-air hole part of the valve disc matching surface 310. At this time, only one open air path exists between the valve core disc 31 and the valve body 4 from the air inlet 41 of the valve body 4 to the normal air outlet 42 of the valve body 4, and the air outlet 43 and the emergency air outlet 44 of the valve body 4 cannot be ventilated because the third valve body face air hole 403 and the fourth valve body face air hole 404 are covered by the valve core disc 31.
In this embodiment, the distance from the third valve disc surface air hole 313 on the valve disc mating surface 310 to the center of the valve disc 31 is smaller than the distance from the other air holes on the valve disc mating surface 310 to the center of the valve disc 31. Of course, the above air path structure can be implemented when the distance from other air holes on the matching surface 310 of the valve core disk to the center of the valve core disk is larger.
As shown in fig. 6, the door emergency control system of the present embodiment includes a cylinder 61, a door control valve 62, a three-way valve 63, an air source 64, and a door quick-opening emergency valve switch 65 of the present embodiment.
The door control valve 62 employs a five-port two-position (also referred to as five-way two-position, etc.) solenoid valve. The electromagnetic valve has five air inlets and air outlets, and has two working states (namely a positive working state and a negative working state, which can be switched by power on and power off), so that the electromagnetic valve is called as five-inlet two-position electromagnetic valve. Specifically, the gas inlet and outlet ports include a gas inlet port 621 (for connecting a gas inlet source), a first gas outlet port 622 (for providing a gas source for positive actuation to a target device in a positive actuation state), a second gas outlet port 623 (for providing a gas source for negative actuation to a target device in a negative actuation state), a positive actuation gas outlet port 624 (for discharging gas from the first gas outlet port 622 when in a negative actuation state), and a negative actuation gas outlet port 625 (for discharging gas from the second gas outlet port 623 when in a positive actuation state); the positive working state means that the air inlet 621 communicates with the first air outlet 622 and the second air outlet 623 communicates with the negative working air outlet 625, i.e. the first air outlet 622 is an air supply end and the second air outlet 623 is an air exhaust end; the reaction operation state means that the air inlet 621 communicates with the second air outlet 623 and the first air outlet 622 communicates with the positive operation air outlet 624, i.e. the second air outlet 623 is an air supply end and the first air outlet 622 is an air discharge end.
The three-way valve 63 employs an on-off valve. The opening and closing valve is a unidirectional directional control element commonly used in pneumatic control, and includes three ports, a first port 631, a second port 632, and a third port 633, respectively. The working principle is as follows: when the third air port 633 supplies air, the corresponding movement of the valve core inside the valve body enables the second air port 632 to be in a communication state with the third air port 633, and meanwhile, the first air port 631 and the second air port 632 are in a closed state; when the third air port 633 is not supplied with air, the valve core moves correspondingly, so that the second air port 632 and the third air port 633 are closed, and the first air port 631 and the second air port 632 are communicated. Therefore, the operation state of the three-way valve 63 can be switched by controlling the air supply state of the third air port 633.
The cylinder 61 is provided to drive a door opening and closing mechanism of a vehicle door to open and close the vehicle door, and has a piston rod 610, and the piston rod 610 is connected to the door opening and closing mechanism 66. The air inlet and outlet of the cylinder 61 includes an opening end air port 612 and a closing end air port 611. The piston rod 610 drives the door opening and closing mechanism 66 to open the door when the door opening port 612 is in the air, and the piston rod 610 drives the door opening and closing mechanism 66 to close the door when the door opening port 611 is in the air.
The gas source 64 functions to provide gas for door opening and closing. The gas circuit connection of the whole vehicle door emergency control system is as follows: the output end of the air source 64 is connected with the air inlet 41 of the valve body 4 in the door quick-opening emergency valve switch 65, the air inlet 621 of the door control valve 62 is connected with the normal air outlet 42 of the valve body 4 in the door quick-opening emergency valve switch 65, the first air outlet 622 of the door control valve 62 is connected with the door closing end air port 611 of the air cylinder 61, the second air outlet 623 of the door control valve 62 is connected with the first air port 631 of the three-way valve 63, the second air port 632 of the three-way valve 63 is connected with the door opening end air port 612 of the air cylinder 61, and the third air port 633 of the three-way valve is connected with the emergency air outlet 44 of the valve body 4 in the door quick-opening emergency valve switch 65.
As can be seen from the foregoing description, the quick-opening emergency valve of the door quick-opening emergency valve switch 65 has two air passage structures under different rotation states, the first air passage structure has two air passages simultaneously, that is, from the air inlet 41 of the valve body 4 to the emergency air outlet 44 of the valve body 4 and from the normal air outlet 42 of the valve body 4 to the air outlet 43 of the valve body 4, and the second air passage structure has only one air passage, that is, from the air inlet 41 of the valve body 4 to the normal air outlet 42 of the valve body. The emergency valve can be switched in both air path configurations by rotating the knob 1 on the door quick-opening emergency valve switch 65.
Therefore, in the door emergency control system of the present embodiment, there are also two gas path structures. As shown in fig. 7 (for convenience of description, other parts of the door quick-opening emergency valve switch 65 are omitted in fig. 7, only the valve body 4 is shown, and the same is true in fig. 8), when the quick-opening emergency valve is in the second air path structure, that is, only one air path, the air from the air source 64 will sequentially pass through the air inlet 41 of the valve body 4, the first valve body face air hole 401 of the valve body 4, the second valve body face air hole 402 of the valve body 4, and the normal air outlet 42 of the valve body 4 to be output to the air inlet 621 of the door control valve 62 through the output ends thereof.
Meanwhile, since the emergency air outlet 44 of the valve body 4 does not output air, the third air port 633 of the three-way valve 63 does not supply air, and at this time, the working state of the three-way valve 63 is that the first air port 631 of the three-way valve 63 is communicated with the second air port 632 of the three-way valve 63, and the second air port 632 of the three-way valve is closed with the third air port 633 of the three-way valve, so that the second air outlet 623 of the door control valve 62 is communicated with the door opening end air port 612 of the air cylinder 61 sequentially through the first air port 631 of the three-way valve and the second air port 632 of the three-way valve. In this state, the normal opening and closing of the door can be performed by switching the intake relationship between the intake port 612 and the two exhaust ports 622 and 623 of the door control valve 62, at which time the normal operation state is the state.
For example, when the door is to be closed, the air intake relationship of the door control valve 62 is switched from the air inlet 621 of the door control valve 62 to the first air outlet 622 connected to the door closing end air port 611 of the air cylinder 61, the air from the air source 64 will enter the door closing end air port 622 of the air cylinder 61, and the air remaining in the door opening end of the air cylinder 61 will sequentially pass through the door opening end air port 612 and the three-way valve 63 to reach the second air outlet 623 of the door control valve 62 communicated with the air inlet and then be discharged through the air outlet 625 of the second air outlet 623, and at this time, the piston rod 610 of the air cylinder 61 operates to cause the door opening and closing mechanism 66 of the door to close the door.
The opposite is true when the door opening process is performed, i.e., the air inlet relation of the door control valve 62 is switched from the air inlet 621 of the door control valve 62 to the second air outlet 623 of the door control valve connected to the door opening port 612 of the air cylinder 61 through the three-way valve 63, the air from the air source 64 will enter the door opening port 612 of the air cylinder 61, and the residual air in the door closing end of the air cylinder 61 will be sequentially discharged through the door closing port 611, the first air outlet 622 of the door control valve 62 and the air outlet 624 of the first air outlet 622, at which time the piston rod 610 of the air cylinder 61 operates to cause the door opening and closing mechanism 66 of the door to open the door.
When the vehicle door is closed in an emergency state, an emergency door opening is required. At this time, the knob on the door quick-opening emergency valve switch is rotated by 90 degrees, so that the emergency valve can be switched to a first gas path structure, namely a structure with two gas paths at the same time. As shown in fig. 8, the gas from the gas source 64 is outputted to the third port 633 of the three-way valve 63 through the output end thereof sequentially through the gas inlet 41 of the valve body 4, the first valve body surface gas hole 401 of the valve body 4, the fourth valve body surface gas hole 404 of the valve body 4, and the emergency gas outlet 44 of the valve body 4. Since the third port 633 of the three-way valve 63 starts to supply air, the operation state of the three-way valve 63 is changed, that is, the second port 632 of the three-way valve 63 is communicated with the third port 633 of the three-way valve 63, and simultaneously, the first port 631 of the three-way valve 63 is closed with the second port 632 of the three-way valve 63, which means that the air from the air source 64 is outputted to the door opening port 612 of the cylinder 61 through the third port 633 of the three-way valve 63 and the second port 632 of the three-way valve. At the same time, the air port 611 at the door closing end of the air cylinder 4 will also sequentially pass through the first air outlet 622 of the vehicle body control valve 62, the air inlet 621 of the vehicle body control valve 62, the normal air inlet 42 of the valve body 4, the second valve body surface air hole 402 of the valve body 4, and the third valve body surface air hole 403 of the valve body 4, which are connected thereto, and finally communicate with the air outlet 43 of the valve body 4, thereby starting the air discharge. Because the door opening port 612 is used for air intake and the door closing port 611 is used for air exhaust, the piston rod 610 drives the door opening and closing mechanism 66 of the door to rapidly open the door, and rapid opening of the door in an emergency state is realized. At this time, an emergency working state is obtained.
Example 2:
the second embodiment of the present application is not much different from the embodiment except that one more exhaust hole is provided in the valve cartridge disc 31.
As shown in fig. 4 and 5, the valve core disc matching surface 310 of the valve core disc 31 of the quick-opening emergency valve in this embodiment is further provided with an exhaust hole 315. The vent hole 315 is located near the third valve disc surface air hole 313, and the vent hole 315 is distributed on the same straight line with the first valve disc surface air hole 311, the third valve disc surface air hole 313 and the center of the valve disc 31, and meanwhile, the vent hole 315 is also distributed on the same circumference of a circle taking the center of the valve disc 31 as the center of the circle, with the first valve disc surface air hole 311, the second valve disc surface air hole 312 and the fourth valve disc surface air hole 314, which means that the distance from the vent hole 315 to the center of the valve disc 31 is equal to the distance from the first valve disc surface air hole 311 to the center of the valve disc 31.
When the door quick-opening emergency valve switch 65 is in a normal working state, the vent 315 rotates to the position where the original fourth valve core disc surface air hole 314 is located, so that the vent 315 is communicated with the fourth valve body surface air hole 404 on the valve body matching surface 40 which is originally matched with the fourth valve core disc surface air hole 314, and further the vent 315 is communicated with the emergency air outlet 44 of the valve body 4. However, since the vent hole 315 is not connected to an external air source, the emergency air outlet 44 of the valve body 4 is still in a state where no air is output at this time, so that the operating state of the three-way valve 63 is not affected, and thus the opening and closing of the vehicle door in the normal operating state is not affected by the vent hole 315.
When the door quick-opening emergency valve switch 65 is in an emergency working state, the exhaust hole 315 is restored to the original position. Since the valve body mating surface 40 has no corresponding air hole at the position opposite to the original position of the air hole 315, the air hole 315 is covered by the air hole-free position of the valve body mating surface 40, and cannot function. The gas path structure of the quick-opening emergency valve is still the two gas paths in the emergency working state in the embodiment 1, so that the opening of the vehicle door in the emergency working state is not influenced by the exhaust hole 315.
When the vent hole 315 is changed from the state covered by the valve body mating surface 40 to the state in communication with the emergency air outlet 44 of the valve body 4 upon switching from the emergency operation state to the normal operation state, if there is still air in the air path between the third air outlet 633 of the three-way valve 63 and the emergency air outlet 44 of the valve body 4 (there is air output from the emergency air outlet 44 of the valve body 4 in the emergency operation state, so that air exists in the air path), the air can be discharged from the vent hole 315. This allows the three-way valve 63 to be quickly restored to the normal operation state, thereby realizing the rapid switching of the door in the emergency operation state to the normal operation state.
While the application has been disclosed in terms of preferred embodiments, the embodiments are not intended to limit the application. Any equivalent changes or modifications can be made without departing from the spirit and scope of the present application, and are intended to be within the scope of the present application.
