Description

Mini-bus passenger vehicle electric controling switch door

The utility model is a kind of mini-bus passenger vehicle automatic door.

At present; Homemade mini-bus passenger vehicle, as Wulin tomb circle, Hunan, Hunan fortune, minibus such as the Zhangjiagang in Jiangsu all are to adopt hand pulling type switch door, and by ticket seller's operation, the ticket seller is not on the doorway sometimes, passenger oneself also can open the door and get off, because bad control, under the driver did not also come to a complete stop the situation of car, the anxious sliding door of passenger was got off, be easy to cause the passenger to fall down, cause the generation of casualty accident.

The purpose of this utility model provide a kind of can be by the car door automatic control switch of driver control, open when guaranteeing that car comes to a complete stop, avoided the generation of casualty accident.

The technical solution of the utility model is, door contact interrupter is fixed on driver's cabin, and door contact interrupter is electrically connected with motor through the switching threshold bit switch, and the break-make of limit switch is by the travel switch control that is fixed on the door.

Above-mentioned travel switch comprises reel and the travel switch inner and outer pipes that is fixed on the motor transmission shaft, wire rope one end of pipe motion is fixed on the reel in the control travel switch, the other end is fixed on the guide head on the inner tube head, in pipe guide head side back-moving spring is housed, interior pipe stretches out outer tunnel end and is fixed on the guide holder on the car door with guiding fork.

Above-mentioned reel is fixed on the power transmission shaft by isolator, the flywheel on operating principle such as the bicycle.

Above-mentioned door open limit switch is fixed on the side, termination, moved end of travel switch, closes that door limit switch is corresponding with the striking plate on the car door to be fixed on the car door frame.

The utility model is owing to be fixed on driver's cabin with door contact interrupter, and by driver's control, so passenger oneself can not open door, so guaranteed on-off passengers's personal safety; In addition, the switch door is controlled by the driver, can save the people of full-time switch car door; The utility model adopts electric switch, and it is simple in structure, and is easy for installation, and power supply is provided by storage battery on the car.

Fig. 1 is an electrical schematic diagram of the present utility model;

Fig. 2 is a structural representation of the present utility model;

Fig. 3 is assemblied in structural representation on the car door for Fig. 2.Further specify the utility model below in conjunction with accompanying drawing.

The utility model adopts positive and negative the transferring of control motor 2 to drive the travel switch motion that is fixed on the car door 21, drive car door 21 simultaneously and open and close, the power switch 1 of motor 2 is fixed in the driver's cabin, is controlled by the driver, switch 1 is electrically connected with motor 2 through limit switch 7,19, as shown in Figure 1; Travel switch comprises reel 4 and the travel switch inner and outer pipes 10 that is fixed on motor 2 power transmission shafts 3,15, wire rope 6 one ends of pipe 10 motions are fixed on the reel 4 in the control travel switch, on the guide head 9 in the other end is fixed on pipe 10 terminations, pipe 10 back-moving springs 8 in guide head 9 sides are equipped with, in pipe 10 stretch out outer tube 15 ends and be fixed on the guide holder 12 on the car door 21 with guiding fork 11, travel switch is by outer tube external and

internal fixation bolt

14,13 are fixed on the support 18, motor 2 and power transmission shaft 3 are separately fixed on

support

16 and 17, limit switch 7 is the door open limit switch, be fixed on the side, termination, moved end of travel switch, as shown in Figure 2; Reel 4 is fixed on the power transmission shaft 3 by isolator 5, and isolator 5 is a kind of clutches, the flywheel on its operating principle such as the bicycle, reel 4 is fixed on the isolator 5 by screw socket, isolator 5 by bearing fixing on power transmission shaft 3; Travel switch is fixed on the interior page or leaf 21 of car door, and limit switch 19 is fixed on the car door frame for closing door limit switch. and corresponding with the striking plate 22 on outside the car door page 20, as shown in Figure 3.

Operating principle: when opening door contact interrupter 1, motor 2 is connected power supply through limit switch 7, motor 2 work, drive isolator 5 and reel 4 rotations by power transmission shaft 3, wire rope 6 is involved in line takes turns in 4 grooves, simultaneously, pipe guide head 9 in the wire rope 6 pulling travel switches, interior pipe 10 moves to reel 4 directions under the drive of guide head 9, and compression spring 8, in pipe 10 when moving by guiding fork 11 and be fixed on the guide holder 12 on the page or leaf 21 in the car door, drive that page or leaf 21 is pulled in the car door, with car door opening, when car door arrives the fully open position, travel switch collision limit switch 7 makes its outage, and motor stops 2 work; When door contact interrupter 1 being pulled when closing the door the position, motor 2 is connected power supply through limit switch 19, the motor counter-rotating, because the effect of isolator 5, reel 4 is not subjected to the control of motor transmission shaft 3, at this moment, interior pipe guide head 9 sets back under the effect of spring 8, door is shut, and when door was closed fully, the striking plate 22 collision limit switches 19 on the outer page or leaf 20 of car door quit work motor 2 outages.
