Abstract
An anti-clamping device of a bus door is characterized in that the anti-clamping device of the bus door comprises a spring catch (1) which is arranged at the corresponding door edge of the door at one side and a pressure lever switch (2) which is arranged between the spring catch (1) and the door, wherein an embedding groove (3) for holding a head of the spring catch (1) is arranged at the door edge of the door at the other side corresponding to the spring catch (1); and the pressure lever switch (2) is connected with a door-opening switch (4) in parallel through a line and is then connected with a door pump solenoid valve (5) and a vehicular power supply in series to form a loop. The utility model has the advantages that the anti-clamping device is simple and practical, the door can be automatically opened when passengers are clamped, the passengers can be effectively prevented from being clamped, and the accidents are avoided.
Description
Technical field
The utility model relates to bus door, is a kind of bus door anti-jamming device specifically.
Background technology
Present bus changes self-service ticketing into more, and the switch at back door is also changed by the driver by original ticket seller's control have been controlled.But because the driver can only observe the passenger loading situation by rearview mirror, the driver therefore usually occurs and close the door too early and the passenger is clamped, passenger's body is damaged.The bus that has is equipped with camera and aims at the back door, but under the too many situation of passenger, the driver still can't see last passenger's situation clearly from camera, still can not tackle the problem at its root.So we need the automatic anti-jamming device on a kind of car door.
Summary of the invention
The purpose of this utility model provides a kind of bus door anti-jamming device of practicality.
Described bus door anti-jamming device is characterized in that: this bus door anti-jamming device comprises the spring latch lock at the phase opposite house edge place that is installed in a sidecar door, and is installed in the depression bar switch that bumps between pearl and the car door; Have one and hold and bump the groove that embeds that pearl meets and discusses with the described relative opposite side car door door edge place of pearl of bumping; Described depression bar switch constitutes the loop by connecting with door pump electromagnetic valve, vehicle power again after circuit and the door open switch parallel connection.
The utility model is simple and practical, and folder can open the door when meeting the passenger automatically, prevents that effectively the passenger from being crushed by car door, can avoid unsafe accident to take place.
Description of drawings
Fig. 1 is the utility model structural representation,
Fig. 2 is an A partial enlarged drawing among Fig. 1,
Fig. 3 is the utility model electrical principle block diagram.
Among the figure: 1-bumps pearl, 2-depression bar switch, and 3-embeds groove, 4-door open switch, 5-door pump electromagnetic valve.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further specified: bus door anti-jamming device described in Fig. 1,2,3 comprises the spring latch lock 1 at the phase opposite house edge place that is installed in a sidecar door, and is installed in the depression bar switch 2 that bumps between pearl 1 and the car door; With described bump the relative opposite side car door door edge place of pearl 1 have one hold bump that pearl 1 meets and discusses embed groove 3; Described depression bar switch 2 constitutes the loop by connecting with door pump electromagnetic valve 5, vehicle power again after circuit and door open switch 4 parallel connections.
Bus door is opened, closed principle: bus all is a pneumatic door generally, and door contact interrupter is controlled by the driver at bridge.Press door contact interrupter, the energising of door pump electromagnetic valve, gas circuit is connected, the air inlet of door pump, car door is just opened; On the contrary, the closed door switch, the outage of door pump electromagnetic valve, the exhaust of door pump, car door is just closed.
Explanation the utility model principle and embodiment as shown in Fig. 1, Fig. 2, Fig. 3:
The situation of opening the door:
The driver presses door contact interrupter 4,5 energisings of door pump electromagnetic valve, and gas circuit is connected, the air inlet of door pump, car door is just opened.Bumping pearl 1 is not having to be in static shape under the stressing conditions, and the extrusion that its inboard depression bar switch 2 is not subjected to bumping pearl 1 is in the disconnection shape.
Close the door and press from both sides people's situation:
The driver disconnects door contact interrupter 4,5 outages of door pump electromagnetic valve, and the exhaust of door pump, car door is about to close.If the passenger occurs pressed from both sides this moment, passenger's health will touch and bump pearl 1, bump pearl 1 and be extruded and move inward, and the inboard depression bar switch 2 of extruding in moving, depression bar switch 2 is the conducting shape after pressing.
After 2 conductings of depression bar switch, a pump electromagnetic valve 5 is powered once more, and gas circuit is connected, the air inlet of door pump, and car door just is opened once more, and car door has just pressed from both sides not the passenger.
When the passenger up got in the car again, passenger's health was no longer touched when bumping pearl 1, bumped pearl 1 and ejected the recovery former state.Depression bar switch 2 also restores to the original state under no extruding situation, is the disconnection shape, 5 outages of door pump electromagnetic valve, and the exhaust of door pump, car door is normally closed.
The described diameter that bumps pearl can be according to the actual conditions adjustment with the coefficient of elasticity of bumping the pearl contained spring.
