Abstract

The utility model discloses a bus door closing and opening system, comprising a laser pulse device, a master controller, a motor, a synchronous belt, a door leaf hanger and a door body, wherein the laser pulse device is used for transmitting a laser signal to the master controller which controls the motor to run after making a judgment on the laser signal, the motor drives the synchronous belt to rotate, and the synchronous belt is connected with the door leaf hanger for controlling a door body to rotate. The bus door closing and opening system disclosed by the utility model can be used for automatically opening the bus door when a bus arrives at a station, so that the work load of a driver is reduced, and route delay caused by delayed manual operation of the driver is avoided, and the bus door closing and opening system is convenient to use, high in efficiency and more humanized.

Description

The bus door opening and closing system

Technical field

The utility model relates to a kind of bus door opening and closing system.

Background technology

The door opening and closing system that uses on the bus now is the combination of adopting gas ability principle and lever principle basically.During driver's Push switch, pulsometer is just stretched a support rod top, and the top of this gas rod is connected on the car door, when stretch on the top, with car door opening, during contraction, car door is shut.Yet there is following shortcoming in above-mentioned door opening and closing system: the driver needs the button that manual manipulation control gate body opens and closes when bus arrival; Increased driver's workload on the one hand; Make tired driver easily; And then influence the safety of driver driving, usually delay stroke on the other hand because of driver operation is untimely.

The utility model content

In order to solve the problems of the technologies described above, the utility model provides a kind of bus door opening and closing system.

Its technical solution is:

A kind of bus door opening and closing system; It comprises laser pulse device, master controller, motor, synchronous band, door leaf hangs and the door body; The laser pulse device is passed to master controller with laser signal; The running of control motor after master controller is judged laser signal, motor drives is with rotation synchronously, and band hangs with the door leaf of control gate body rotation and is connected synchronously.

Further, above-mentioned bus door opening and closing system also comprises photoelectric detection switch and door open limit switch, and photoelectric detection switch is connected with master controller respectively with the door open limit switch.

The useful technique effect of the utility model is:

Automatically open car door when the utility model can and have the people to get on or off the bus at bus arrival, reduced driver's workload, and avoided because of the untimely stroke that delays of driver's manual operation, easy to use, efficient is high, hommization more.

Description of drawings

Below in conjunction with the accompanying drawing and the specific embodiment the utility model is described further:

Fig. 1 is the catenation principle sketch map of the utility model.

Among the figure: 1-laser pulse device; The 2-master controller; The 3-motor; 4-is with synchronously; The 5-door leaf hangs; 6-door body; The 7-photoelectric detection switch; 8-door open limit switch; The 9-back off timer.

The specific embodiment

In conjunction with accompanying drawing; A kind of bus door opening and closing system; Comprise laser pulse device 1, master controller 2, motor 3, be with 4 synchronously, door leaf hangs 5 and door body 6, laser pulse device 1 is installed in respectively on the bus and the place, bus station, the two produces laser signal and laser signal is passed to master controller 2 near the back; Master controller 2 receives laser signal and judges 3 runnings of back control motor; Motor 3 drives is with 4 to rotate synchronously, hang 5 with 4 with the door leaf of control gate body 6 rotations synchronously and be connected, and then control gate body 6 is opened.After bus left website, single laser pulse device no longer produced laser signal, and door body 6 can be closed under the effect of the screen resilience of the coupled spring that connects automatically.

Whether above-mentioned bus door opening and closing system will be opened under the effect at laser pulse signal at bus arrival back door body 6 automatically, no matter have the passenger to get on the bus or to get off, obviously intelligent not enough.Further, in the position near door body 6 photoelectric detection switch 7 and door open limit switch 8 are installed, photoelectric detection switch 7 is connected with master controller 2 respectively with door open limit switch 8.This moment, master controller 2 was just controlled motor operation after need receiving the signal that laser pulse signal and photoelectric detection switch pass over simultaneously.And photoelectric detection switch 7 only just transmits signal to master controller when the passenger is arranged near the door body.When the door body reaches maximum open position, activate door open limit switch 8 in addition, door open limit switch 8 transmits signal to master controller, and then the counter-rotating of control motor, drives the door body and closes.

Further; In order to reserve enough getting on or off the bus the time to the passenger, can set up a back off timer 9 and link to each other with the door open limit switch, back off timer 9 can carry out a body opening time and set; As be set at 8 seconds; Then after the door body reached maximum open position and delayed time 8 seconds, the door open limit switch just transmitted signal to master controller, and a body is closed.In addition, in 8 second stand-by period after the door body is opened,, after must restarting to wait for 8 seconds, get into the program of closing the door again, guarantee that personal security passes through if when the passenger is arranged from outside to inside or from inside to outside through photoelectric detection switch 7.

Need to prove that under the instruction of this manual, any equivalents that those skilled in the art have done, or obvious variant all should be within the protection domains of the utility model.
