Description
Technical field
The present invention relates to Vehicular door field, be specifically related to a kind of Vehicular door driving mechanism of outside automatic sliding.
Background technology
The passenger doors of car door especially passenger getting on/off is the important component part of motor bus and track train, is the lower channel of passenger.What the passenger on public transport door of current large discharge was conventional is inner swing door; Track train is level and smooth sliding door and outer sliding door.Inner swing door, there is door blow-by, active channel space from project organization, there is injury risk, Bus inner layout unsightly to occupant in self, and outer sliding door is best suited for and uses on jumbo bus; Scheme (the outer slippage door mechanism system of 200620025131 door for coachs of the existing patent of outer sliding door; 200520024867.7 automatic sliding device of bus doors) show mechanism and upper and lower lazy-tongs with the existing outer sliding door driving mechanism used outward in addition apart from slideway, roller trolley, therefore complex structure cost is high, not easily be transplanted on motor bus and use, also use on motor bus without outer sliding door so far; And the running part of the outer sliding door structure that car uses has cable pulley type, and cable pulley type is limited for application life, the switch life standard of car door is 100,000 times, the switch life standard of motor bus and track train door is 50 to 100 ten thousand times, and the seizing wire of car cable pulley type when driving car door to run to turning wire rope and slideway be rub to run, therefore the life-span is more limited.
Summary of the invention
Technical problem to be solved by this invention is to provide motor bus and the novel outer sliding door driving mechanism of track train, and its driving mechanism is simpler than original mechanism, decreases originally to show mechanism and linkage from top to bottom mechanism.
The present invention is achieved by the following technical solutions:
The outer sliding door driving mechanism of vehicle comprises sliding door connector, slideway, roller trolley, also comprises driver gear, flexible rack, sheath.Flexible rack is placed in the sheath of tubulose, to ensure that flexible rack can only move around all the time in sheath, sheath is arranged along slideway and is fixed, in the scope that sliding door connector runs, sheath has one along the open slot in length direction, sliding door connector is connected with flexible rack by the open slot on sheath, and driver gear is connected by its gear shaft and is fixed on vehicle body, and engage with flexible rack, flexible rack can be drive in sheath to move around.Sheath can be along slideway straight line, also can be along slideway curved arrangement; To be employing steel wire by certain pitch be fastened flexible rack outside Bowden cable forms flexible axle tooth bar; Flexible rack also can have hole, garden by many centres, with hole, garden for axle, pierces on flexible ropy, make its every to connect and form flexible axle tooth bar with the revolving body that the favourable curve becoming profile of tooth is formed around the scanning of hole, garden axle; Flexible rack also can be adopted made of plastic; Sheath is hard form matter, is metal or plastics.One section of flexible shroud is had to overlap with outside the flexible rack at the flexible rack two ends of driver gear engagement place.Such driving total performance can arbitrarily be arranged.Slideway due to outer sliding door is bending, sheath just can along slideway curved arrangement, sliding door connector is owing to being connected on flexible rack, and flexible rack can only be drive and moves around in sheath, and then the commutation of motor drives sliding door to move around close door.Men Bingke along bending track show into.
Beneficial effect:
Compared with prior art, driving mechanism of the present invention adopts flexible rack can bend in sheath and runs back and forth, and by the layout along outer sliding door slideway, and driven wheel is beyond slideway, such scheme is simpler than the outer sliding door driving mechanism technology of existing track train, decreases too fat to move to show mechanism and upper and lower lazy-tongs, with the outer sliding door cable pulley type driving mechanism ratio that car uses, cable pulley type driving mechanism steel cable must be that closed loop connects ability transmission, and have interference to other mechanism (as glass-frame riser mechanism), occupy, not easily arrange, and thin steel rope runs at turning and track friction, and the present invention program's gear drive flexible rack, layout is the unidirectional layout along slideway, and driven wheel part is flexibly connected by flexible shroud beyond operation slideway, length can be determined because of needs, therefore, the motor driving volume maximum is be connected by single flexible sheath with driven wheel, and arbitrarily can be arranged in any suitable position, it solve the problem of difficult arrangement on vehicle body.Due to the seizing wire sectional area that flexible rack sectional area drives much larger than cable pulley type, therefore this programme drives the seizing wire pressure that the pressure of friction place when turning drives far below cable pulley type, the frictional force of often is little many like this, the seizing wire that cable pulley type drives forms with many tiny steel wire windings, a disconnected finer wire when rubbing, whole steel cable will be scrapped very soon, loss of function.This scheme is particularly applicable to car.

Detailed description of the invention
To implement the outer sliding door of motor bus list fan:
As shown in Figure 1, Figure 2, Figure 3 shows, sliding door constrains on vehicle body by sliding door connector and each roller trolley by upper, middle and lower three band cambered way by outer sliding door, door can be shown with slideway and slide to the outer side of vehicle body, also can putting into shutting with slideway, developing with vehicle body.Driving mechanism assembly is arranged on glide path.Flexible rack is placed in the protective metal shell of tubulose, sheath is arranged along glide path and is fixed with glide path, in the scope that sliding door connector runs, sheath has one along the open slot in length direction, sliding door connector is fixedly connected with at P place with flexible rack by the open slot on sheath, driver gear is connected by its gear shaft and is fixed on vehicle body, and engage with flexible rack, to be employing steel wire by certain pitch be fastened flexible rack outside Bowden cable forms flexible axle tooth bar; Flexible rack can be drive in sheath to move around, and so sliding door just can be driven to show unlatching, put into closedown.One section of flexible shroud is had to overlap outside the flexible rack at the two ends of driver gear engagement place.Driving mechanism assembly is facilitated to be arranged into suitable any position according to the situation of vehicle body thus.As position allow driving mechanism assembly also can directly and the protective metal shell at slideway place be fixed together, the flexible shroud between saving.
Flexible rack can adopt steel cable to connect in centre-drilling hole with steel ball and form, and gear just adopts corresponding circle-arc tooth.
Flexible rack can make it have some flexible as nylon injection-molding forms with wear-resistant plastic.
Sheath can process with steel plate roll-forming, also can be injection molded with plastics.
