Abstract
The utility model discloses a safe open control system for a passenger door of a passenger car. The safe open control system for the passenger door of the passenger car comprises an air reservoir, a passenger door control switch, a parking braking quick release valve, a spring braking chamber and a passenger door pump electromagnetic valve, wherein the passenger door control switch and a passenger door pump are connected with a power circuit through the passenger door control switch, and the parking braking quick release valve is connected with the spring braking chamber. The safe open control system for the passenger door of the passenger car further comprises a normally-on electromagnetic valve, wherein a coil of the normally-on electromagnetic valve and the passenger door pump electromagnetic valve are connected in parallel and are connected with the power circuit , a first port of the normally-on electromagnetic valve is connected with the air reservoir, a second port of the normally-on electromagnetic valve is connected with the parking braking quick release valve, and a third port of the normally-on electromagnetic valve is used as an exhaust port. When the passenger door is opened, the passenger car is parked and the passengers are guaranteed to get on and off the passenger car safely.
Description
Technical field
The utility model relates to a kind of passenger door safe opening control system of large and medium bus.
Background technology
The large and medium bus of prior art is not monitored the running state of vehicle after passenger door is opened, and opens the back vehicle when passenger door and still can continue operation, if at this moment passenger getting on/off is arranged, has potential safety hazard even causes personal safety, causes danger.
Summary of the invention
The utility model provides a kind of bus passenger door safe opening control system in order to solve the prior art above shortcomings; Make under passenger door is in opening, guarantee that the passenger can safe getting on or off the bus thereby vehicle is in the Parking state.
The purpose of this utility model is to adopt following technical proposals to realize:
A kind of bus passenger door safe opening control system, comprise air receiver, the passenger door master cock, the braking during standstill rapid release valve, the brake application by spring air chamber, passenger's every pump electromagnetic valve, passenger door master cock wherein, passenger's every pump electromagnetic valve is connected with power circuit by the passenger door master cock, the braking during standstill rapid release valve is connected with the brake application by spring air chamber, also comprise the normal opened type electromagnetic valve, the coil of normal opened type electromagnetic valve and passenger's every pump electromagnetic valve are connected in parallel in the power circuit, and first interface of electromagnetic valve is connected with air receiver, second interface is connected with the braking during standstill rapid release valve, the 3rd interface is exhausr port.
Principle of work of the present utility model: passenger door is opened when chaufeur is pressed the passenger door master cock, the normal opened type electromagnetic valve is connected power supply simultaneously, this moment, second interface and the 3rd interface of normal opened type electromagnetic valve were connected, because the 3rd interface of normal opened type electromagnetic valve is exhausr port, pressurized air in the brake application by spring air chamber is namely discharged by braking during standstill rapid release valve and normal opened type electromagnetic valve at this moment, thereby the realization parking braking function, it is motionless that vehicle is parked.When chaufeur is oppositely pressed the passenger door master cock, according to systematic schematic diagram, passenger door is closed, while normal opened type electromagnetic valve power cut-off, this moment, second interface and first interface of normal opened type electromagnetic valve were connected, the pressurized air that is stored in the air receiver namely enters the brake application by spring air chamber by the pipeline system of redness, removes braking during standstill, and this car vehicle can normally travel under driver's operation.
The beneficial effects of the utility model:
Guaranteed that vehicle should be in the Parking state under passenger door is in opening, thereby can guarantee that the passenger can safe getting on or off the bus.
Description of drawings
Fig. 1 is structural representation of the present invention;
Wherein, 1. air receiver, 2. normal opened type electromagnetic valve, 3. passenger door master cock, 4. braking during standstill rapid release valve, 5. brake application by spring air chamber, 6. second interface, 7. first interface, 8. the 3rd interface, 9. passenger's every pump electromagnetic valve.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is described further.
A kind of bus passenger door safe opening control system, comprise air receiver 1, passenger door master cock 3, braking during standstill rapid release valve 4, brake application by spring air chamber 5, passenger's every pump electromagnetic valve .9, wherein the passenger door master cock 3, passenger's every pump electromagnetic valve .9 is connected with power circuit by passenger door master cock 3, braking during standstill rapid release valve 4 is connected with brake application by spring air chamber 5, also comprise normal opened type electromagnetic valve 2, the coil of normal opened type electromagnetic valve 2 and passenger's every pump electromagnetic valve 9 are connected in parallel in the power circuit, and first interface 7 of normal opened type electromagnetic valve 2 is connected with air receiver 1, second interface 6 is connected with braking during standstill rapid release valve 4, the 3rd interface 8 is exhausr port.
Passenger door is opened when chaufeur is pressed passenger door master cock 3, normal opened type electromagnetic valve 2 is connected power supply simultaneously, second interface of normal opened type electromagnetic valve 2 and the 3rd interface are connected at this moment, because the 3rd interface of normal opened type electromagnetic valve 2 is exhausr port, pressurized air in the brake application by spring air chamber 5 is namely discharged by braking during standstill rapid release valve 4 and normal opened type electromagnetic valve 2 at this moment, thereby the realization parking braking function, it is motionless that vehicle is parked.When chaufeur is oppositely pressed passenger door master cock 3, according to systematic schematic diagram, passenger door is closed, while normal opened type electromagnetic valve 2 power cut-offs, second interface of normal opened type electromagnetic valve 2 and first interface are connected at this moment, the pressurized air that is stored in the air receiver 1 namely enters brake application by spring air chamber 5 by the pipeline system of redness, removes braking during standstill, and this car vehicle can normally travel under driver's operation.
Though above-mentionedly by reference to the accompanying drawings the specific embodiment of utility model is described; but be not the restriction to the utility model protection domain; one of ordinary skill in the art should be understood that; on the basis of the technical solution of the utility model, those skilled in the art do not need to pay various modifications that creative work can make or distortion still in protection domain of the present utility model.
