Description

Economical rammer sliding door driving mechanism

One, technical field

The utility model relates to a kind of drive system of passenger vehicle door, more specifically says so to apply to the driving mechanism of passenger vehicle rammer sliding door.

Two, background technology

Along with The development in society and economy, the safety of passenger door and aesthetic property become more and more important, and particularly since the bus burning incident of Chengdu generation in 2009, the safety of Chinese bus promotes and becomes more urgent.The structure overwhelming majority that present bus door adopts is inner swing door and folding door, because structural reason, inner swing door and folding door must take the passenger vehicle volume inside in the process of opening, in case generation emergency, the passenger occupies the space that car door opens the door to be needed after gathering around the car door place, car door all can't be opened from the outside still car body inside of car body, causes the passenger to escape rapidly, thereby produces bigger security incident.Therefore, extensively adopt stopping sliding door to be one in the public transport field and more can satisfy passenger's choose reasonable of safety by bus.The lengthwise movement of rammer sliding door is at present mainly finished by two or more line slideways, because not only load-bearing but also lead of line slideway, in case owing to the reason of machining accuracy or the external force factor in the use, produce distortion such as the accident rear drive mechanism occurring, cause between the line slideway not parallel, passenger vehicle door switch fluctuation of service, have some setbacks, phenomenon stuck, that car door can't be opened can take place under the egregious cases.This requirement and line slideway cost factor to machining high-precision directly cause rammer tambour door structure complexity, cost an arm and a leg, and are difficult to promote in the public transport field.

Three, summary of the invention

1. goal of the invention:

Limitation at inner swing door and folding door structure, and the rammer sliding door adopts the line slideway technology in the prior art, all exist operation unreliable, complex structure, the cost height, defective such as be difficult to promote the use, the utility model provides a kind of Eco-power rammer sliding door, both solved the problem that car door in case of emergency can't be opened, guaranteed the safety issue in the passenger vehicle running, solved existing rammer tambour door structure complexity again, cost an arm and a leg, be difficult to the problem in the public transport field, promoted

2. technical scheme:

Technical solutions of the utility model are as follows:

A kind of economical rammer sliding door driving mechanism, comprise horizontal two-way cylinder, the transmission ribbon, vertical two-way little cylinder, vertically move pallet load-bearing and guiding mechanism, electrical control system, drive left-hand door page or leaf and right door leaf by a horizontal two-way cylinder by the transmission ribbon, perhaps directly drive left-hand door page or leaf and right door leaf by two horizontal two-way cylinders, vertically move pallet load-bearing and guiding mechanism by vertical two-way little air cylinder driven, realize that vertically the plug roping is moving, and, realize the action of opening the door of stopping sliding door by electrical control system control left-hand door page or leaf and right door leaf translational sideways movement and the vertically moving coordination of plug roping.

A horizontal two-way air cylinder driven left-hand door page or leaf and right door leaf realize that by the transmission ribbon the horizontal reverse sync of left-hand door page or leaf and right door leaf drives.The transmission ribbon wherein, adopts band synchronously including, but not limited to synchronous band, belt, chain, wire rope etc., can reach the transmission effect of economic, reliable and low noise.

Horizontal two-way cylinder adopts Rodless cylinder to drive, and can save the shared horizontal space of driving mechanism like this.

Vertically move the load carrier and the relatively independent layout of guiding device of pallet load-bearing and guiding mechanism, can avoid producing potential mistake orientation problem like this.

Electrical control system is made up of switch door location status checkout gear, electromagnetic valve, anti-clipping system and electromagnetic valve, and anti-clipping system is made up of obstruction acquired signal device and circuit board, and obstruction acquired signal device is made up of closed airbag and sensor.The signal source of obstruction acquired signal device is: after obstruction occurs, cause the volumetric change of closed airbag, volumetric change causes that pressure changes, the information that sensor acquisition changes to pressure, change into the signal of telecommunication again, thereby finish the signals collecting of obstruction acquired signal device.Electrical control system has anti-clipping system, to improve the safety in the passenger vehicle door running.

3. beneficial effect:

The utility model provides a kind of economical rammer sliding door driving mechanism, and compared with prior art, it is simple in structure, and requirement is lower, attractive in appearance relatively, safety is good, cheap for machining accuracy, can be widely used on the rammer sliding door.

Five, the specific embodiment

Below in conjunction with accompanying drawing 1, Fig. 2, Fig. 3, specify the utility model by embodiment:

The state of Fig. 1 is the state of closing the door, provide under the compressed-air actuated situation at source of the gas (14), in the time of need opening the door, circuit board (7) in the electrical control system (5) gets electromagnetic valve (8), vertically two-way little cylinder (3) piston rod shortens, under the load-bearing and guide effect of four BOGEY WHEELs (20) and four directive wheels (21), drive vertically moves the pallet load-bearing and guiding mechanism (4) is outside mobile to passenger car body (22), thereby drive left-hand door page or leaf (12) and right door leaf (13) are outside mobile to passenger car body (22).On the other hand, the circuit board (7) of electrical control system (5) gets electromagnetic valve (11), horizontal two-way cylinder (1) piston moves to left, connecting rod (15) drive transmission ribbon (2) the top band that is fixed on the piston moves to left, the bottom band moves to right, the connecting rod (16) that is fixed on the band of transmission ribbon (2) top drives left-hand door plate hook (17), and left-hand door plate hook (17) drives left-hand door page or leaf (12) and moves to left; The connecting rod (18) that is fixed on simultaneously on the band of transmission ribbon (2) top drives right door-plate hook (19), and door-plate hook (19) drives right door leaf (13) and moves to right, and finally realizes the action that pulls the door open of whole plug.

The state of Fig. 2 is a door opening state, the operating principle of closing the door with open the door opposite.

As shown in Figure 3, wherein dotted line is a gas circuit, and wave is a circuit.If in the process of closing the door, promptly before switch door location status checkout gear (6) does not provide the signal of door-closing in-place, obstruction acquired signal device (10) in the anti-clipping system (9) since closed airbag after running into obstruction, volumetric change produces pressure and changes, the pressure variation changes into the signal of telecommunication, and with electrical signal transfer to anti-clipping system (9), anti-clipping system (9) passes the signal along to the circuit board (7) in the electrical control system (5), circuit board (7) control electromagnetic valve (8) in the electrical control system (5) and electromagnetic valve (11) are reverse, as the above-mentioned process of opening the door, left-hand door page or leaf (12) and right door leaf (13) are opened, avoided in the process of closing the door, crushing the passenger.
