The utility model relates to a kind of automobile door switch device, particularly a kind of box vehicle door electric opening and closing device.

At present, the car door of small-sized box type automobile is generally side and opens the door, car door is along a side of automobile and open, the track that is opened the door and the parallel sidewalls of automobile, when this car uses as taxi, when getting on and off, the passenger needs own open and close automotive door, and automotive door does not shut sometimes, shut automotive door after also needing the driver to stop and travel again, make troubles for passenger and driver.

The purpose of this utility model is that a kind of automotive door box vehicle door electric opening and closing device of open and close automatically will be provided.

The purpose of this utility model has been achieved in that a motor, motor is connected with control box, motor is connected with rope drum by reductor, side at rope drum has movable pulley, and opposite side has assembly pulley, is wound with wire rope on rope drum, steel wire disk is arranged on rope drum, movable pulley and assembly pulley, rope drum is positioned on the wire rope of movable pulley one side, is connected with connecting buckle on the wire rope of movable pulley opposite side, and connecting buckle is connected with automotive door.

Be connected with safety pin, aperture limit switch and close limit switch on the track of automotive door operation.

Movable pulley is connected with car body by spring; Assembly pulley is made of a fixed pulley, fixed two pulleys, fixed three pulleys and a moving pulley, a moving pulley is between fixed two pulleys and fixed three pulleys, a moving pulley is connected with microswitch by spring, fixed two pulleys, a moving pulley, fixed three pulleys are being decided between a pulley and the movable pulley, and are being in the same side with rope drum.

Control box has door open switch, pass door switch and receiver to be connected on the bridge, also has a remote controller, opens the door, closes door switch on the remote controller, and the switch on the receiver is in parallel with gauge tap, and control box is connected with battery.

Owing to adopted such scheme, press door open button or remote controller door open button, the car door safety pin is opened, the motor connecting power rotation, slow down through reductor, the rotation of drive rope drum, rope drum drives the wire rope motion, by moving, the fixed pulley commutation, tensioned, connecting the down fixing of clasp, wire rope affects car door along the slideway translation, meet car door maximum opening limit switch and make circuit obstructed, motor stops operating, and car door is all opened, stop motion, press door close button or remote controller door close button, motor connecting power rotates round about, and car door moves round about along slideway, when meeting the pass door limit switch, circuit is obstructed, and motor stops operating, the car door stop motion, safety pin inserts pin-and-hole thereupon, the car door pin is dead, when car door meets obstructions in motion process, promptly works as people's car door in the process of getting on the bus and just begins to close, close by the microswitch that spring is connected with a moving pulley, make the motor stall, prevented that effectively car door from squeezing the accident of hurting sb.'s feelings and taking place in closing closed procedure, reached the purpose of this utility model.This door electric opening and closing is by pressing button or remote control buttons, come the automatic open and close of Control of Automobile car door, driver or occupant's labour intensity is alleviated, and can effectively prolong the application life of car door, particularly electrification and the automaticity that improves vehicle had good effect.

Be described further in conjunction with the embodiments with reference to the accompanying drawings below.

Fig. 1 is a structural representation of the present utility model.

Fig. 2 is the utility model circuit theory diagrams.

Fig. 3 is the utility model remote controller structural representation.

Embodiment a: motor 1 is arranged, motor 1 is connected with control box 20, motor 1 is connected with rope drum 3 by reductor 2, side at rope drum 3 has movable pulley 5, and opposite side has assembly pulley, is wound with wire rope 4 on rope drum 3, there is wire rope 4 to be coiled on rope drum 3, movable pulley 5 and the assembly pulley, rope drum 3 is positioned on the wire rope 4 of movable pulley 5 one sides, is connected with connecting buckle 10 on the wire rope 4 of movable pulley 5 opposite sides, and connecting buckle 10 is connected with car door 9.

Be connected with safety pin 8, aperture limit switch 7 and close limit switch 11 on the track of automotive door 9 operations.

Movable pulley 5 is connected with car body by spring 6; Assembly pulley is made of a fixed pulley 12, fixed two pulleys 13, fixed three pulleys 17 and a moving pulley 14, a moving pulley 14 is between fixed two pulleys 13 and fixed three pulleys 17, a moving pulley 14 is connected with microswitch 16 by spring 15, fixed two pulleys 13, a moving pulley 14, fixed three pulleys 17 are being decided between a pulley 12 and the movable pulley 5, and are being in the same side with rope drum 3.

Control box 20 has door open switch 22, close door switch 23 and receiver is connected on the bridge, also has a

remote controller

24, and 25 the pass door switch 26 of opening the door out is arranged on the remote controller, and the switch on the receiver is in parallel with gauge tap, and control box 20 is connected with battery 18.

Motor 1 provides the power of car door 9 switches, and to use value, rotating torque becomes big to reductor 2 simultaneously with motor 1 speed drop.Rope drum 3 links to each other with 2 of reductors, wire rope 4 is on rope drum 3, under the effect of frictional force, wire rope 4 is made positive motion with rope drum 3, movable pulley 5, a moving pulley 14, a fixed pulley 12, fixed two pulleys 13, fixed three pulleys 17, spring 6 and the spring 15 common commutation tensioning closed loop moving systems that form wire rope 4.Safety pin 8 is sold when car door 9 fastening positions extremely, prevents car door 9 unexpected unlatchings.Wire rope 4 couples together by being connected clasp 10 with car door 9, microswitch 16 is closed the door when being hampered when car door 9 midway, move on the moving pulley 14, under the affecting of spring 15, microswitch 16 closures, signal passes to control box 20, by control box 20 with battery 18 dumps, motor 1 no current flows through and stops operating, the car door stop motion.After pressing door open button 22 or remote controller 24 door open buttons 25, safety pin 8 is opened, battery 18 electric currents are through the control of control box 20, motor 1 is just changeing, after reductor 2 slows down, output shaft drives rope drum 3 rotations, and wire rope 4 moves under the driving of rope drum 3, and wire rope 4 is owing to connect the fixing of clasp 10, driving car door 9 moves to the direction of opening the door, when car door 9 moves to when touching maximum opening limit switch 7, limit switch 7 closures, signal passes to control box 20, control box 20 cuts off the power supply of battery 18, motor 1 stops operating, and car door also stops to move thereupon, and the worker that opens the door is with finishing.Press door close button 23 or remote controller 24 door close buttons 26, battery 18 electric currents are through the control of control box 20, motor 1 counter-rotating, car door 9 moves to the direction of closing the door, when touching fastening position limit switch 11, limit switch 11 closures, signal passes to control box 20, and the dead car door 9 of control box 20 control safety pins, 8 pins cuts off the power supply of battery 18 simultaneously, motor 1 stops operating, and car door 9 has also stopped moving to the direction of closing the door thereupon.The work of closing the door is finished.Find out that thus car door 9 has been realized the purpose of electronic open and close under the manipulation of car door door open button 22, car door pass button 23 or distant controller 24 door open buttons 25, door close button 26.
