when the three-way electromagnetic valve is powered off, two valve ports connected with the door pump electromagnetic valve and the first emergency valve in the three-way electromagnetic valve are communicated, and the valve port connected with the air storage cylinder is closed.
The invention also provides a protection strategy for forbidding the door to be opened in the driving process, which comprises the following steps:
1) when the vehicle is not started or the vehicle speed is lower than 5KM/H, a door control circuit for controlling the action of a door actuating mechanism in the vehicle normally works, the electric switch door normally functions, the gas circuits of the first emergency valve and the second emergency valve normally work, and the passenger door can be normally opened through the first emergency valve or the second emergency valve;
2) when the vehicle speed is more than 5KM/H, the door control system in the vehicle cuts off the power supply of the door switch, so that the passenger door cannot be opened through the electric control system in the vehicle, meanwhile, the door control system controls the three-way electromagnetic valve to cut off the air sources of the first emergency valve and the second emergency valve, and the air source of the air storage cylinder is led into the door pump electromagnetic valve through the three-way electromagnetic valve, at the moment, the first emergency valve and the second emergency valve fail to work, and the air source of the door actuating mechanism cannot be cut off no matter the two emergency valves are opened or closed; when the speed of the vehicle is reduced to be below 5KM/H, the door control system controls the three-way electromagnetic valve to connect the air sources of the first emergency valve and the second emergency valve, and simultaneously disconnects the air source of the air storage cylinder to the door pump electromagnetic valve, and the two emergency valves can recover to be in a normal working state.
Further, the opening or closing of the passenger door in the automobile is realized by the inflation or deflation of the door pump solenoid valve, and when the door pump solenoid valve inflates the door actuator, the passenger door is closed; when the door pump solenoid releases the air pressure from the door actuator, the passenger door opens.
The invention has the following beneficial effects:
the invention has simple structure and convenient operation, ensures that the passenger door can not be opened in any form during the running process of the vehicle, ensures the life safety and property safety of passengers, and adds a safety for the whole vehicle during the running process.
Description of the drawings:
FIG. 1 is a block diagram of the present invention.
FIG. 2 is a circuit control diagram of the present invention.
The specific implementation mode is as follows:
the invention will be further described with reference to the accompanying drawings.
Referring to fig. 1 and 2, the protection system for forbidding the door opening in the driving process comprises a door actuator 1, a door pump electromagnetic valve 2, a three-way electromagnetic valve 3, a first emergency valve 4, a second emergency valve 5 and an air storage cylinder 6. Two valve ports of the door pump electromagnetic valve 2 are connected with the door actuating mechanism 1, three valve ports of the three-way electromagnetic valve 3 are respectively and correspondingly connected with the valve port of the door pump electromagnetic valve 2, the valve port of the first emergency valve 4 and the air outlet of the air storage cylinder 6, the valve port of the first emergency valve 4 is correspondingly connected with the valve port of the second emergency valve 5, and the second emergency valve 5 is connected with the air outlet of the air storage cylinder.
When the three-way electromagnetic valve 3 is powered on, two valve ports connected with the door pump electromagnetic valve 2 and the air storage cylinder 6 in the three-way electromagnetic valve 3 are communicated, and a valve port connected with the first emergency valve 4 is closed, namely the valve ports 1 and 3 of the three-way electromagnetic valve 3 are communicated, and the valve port 2 is closed.
When the three-way electromagnetic valve 3 is powered off, two valve ports connected with the door pump electromagnetic valve 2 and the first emergency valve 4 in the three-way electromagnetic valve 3 are switched on, and a valve port connected with the air storage cylinder 6 is closed, namely the valve ports 1 and 2 of the three-way electromagnetic valve 3 are switched on, and the valve port 3 is closed.
The protection strategy of the invention is as follows:
1) when the vehicle is not started or the vehicle speed is lower than 5KM/H, a power supply is output from a vehicle control pin in the vehicle door control circuit, the relay is attracted, the power supply does not exist at the controller pin of the three-way electromagnetic valve 3, the three-way electromagnetic valve 3 is in a state that the port 1 and the port 2 are communicated, and the gas path trend is from the gas storage cylinder gas source 6 to the second emergency valve 5 and the first emergency valve 4, is communicated to the door pump electromagnetic valve 2 through the port 1 and the port 2 of the three-way electromagnetic valve, and then to the door actuating mechanism 1. If any one of the second emergency valve 5 and the first emergency valve 4 is opened at this time, the opened corresponding emergency valve cuts off the gas path of the auxiliary gas cylinder 6 and the door actuator 1, the door mechanism will release the pressure through the second emergency valve 5 and the first emergency valve 4, and the door can be opened easily by external force.
The door control circuit mentioned in the invention is the most conventional control circuit of the existing vehicle, so the invention does not repeat the principle of the door control circuit.
2) When the speed of a vehicle is greater than 5KM/H, the whole vehicle control pin in the door control circuit stops outputting, the controller pin in the three-way electromagnetic valve 3 is connected with a normal fire, the opening 1 and the opening 3 of the three-way electromagnetic valve are controlled to be connected, and the opening 2 is disconnected, at the moment, a door air source is directly provided for the door actuating mechanism 1 from the air storage cylinder through the opening 1 and the opening 3 of the three-way electromagnetic valve, and in the state, no matter which emergency valve is opened, the air passage between the door actuating mechanism 1 and the air storage cylinder 6 cannot be cut off, so that the door cannot be opened by external force. Thereby ensuring the personal safety and property safety of passengers in the driving process of the vehicle. When the vehicle speed is recovered to 5KM/H, the control pin of the whole vehicle has power supply output, so that the vehicle door can be opened smoothly under the condition of meeting special conditions through normally opening the door through the emergency valve.
The opening or closing of the passenger door in the automobile is realized by the inflation or deflation of the door pump electromagnetic valve 2, and when the door pump electromagnetic valve 2 is inflated to the door actuating mechanism 1, the passenger door is closed; when the door pump solenoid valve 2 releases the air pressure of the door actuator 1, the passenger door is opened.
The foregoing is only a preferred embodiment of this invention and it should be noted that modifications can be made by those skilled in the art without departing from the principle of the invention and these modifications should also be considered as the protection scope of the invention.
