Description

The outer sliding door drive mechanism of vehicle

Technical field

The present invention relates to Vehicular door field, be specifically related to the Vehicular door drive mechanism of a kind 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 leading to up and down of passenger Road.What the passenger on public transport door of big at present flow was commonly used is inner swing door；Track train is smooth sliding door and outer sliding door.Inner swing door, There is door blow-by, active channel space from design structure, there is injury risk, Bus inner layout to occupant unsightly in self, And outer sliding door is best suited for using on jumbo bus；Scheme (200620025131 visitors of the existing patent of outer sliding door The outer sliding door mechanism system of car door；200520024867.7 automatic sliding device of bus door) drive machine with the existing outer sliding door using Structure also shows mechanism and upper and lower lazy-tongs in addition to having slideway, roller trolley, and therefore the complicated cost of structure is high, is difficult to transplant Use on motor bus, also use on motor bus without outer sliding door so far；And the driving section of the outer sliding door structure using on car Dividing has cable pulley type, and cable pulley type is limited for service life, and the switch life standard of car door is 100,000 times, motor bus and track train The switch life standard of door is 50 to 100 ten thousand times, and the seizing wire of car cable pulley type drives car door to run to steel wire during turning Rope and slideway are that friction runs, and therefore the life-span is more limited.

Content of the invention

The technical problem to be solved is to provide the motor bus outer sliding door drive mechanism novel with track train, and it drives Mechanism is simpler than original mechanism, decreases and original shows mechanism and linkage from top to bottom mechanism.

The present invention is achieved by the following technical solutions:

The outer sliding door drive mechanism of vehicle includes sliding door connector, slideway, roller trolley, also includes driver gear, flexibility Tooth bar, sheath.Flexible rack is placed in the sheath of tubulose, to ensure that flexible rack can only move back and forth all the time in sheath, protects Set is arranged along slideway and fixes, and in the range of sliding door connector runs, has opening along length direction on sheath Mouth groove, sliding door connector is coupled with flexible rack by the open slot on sheath, and driver gear is coupled simultaneously by its gear shaft Being fixed on vehicle body, and engaging with flexible rack, flexible rack can be moved back and forth by drive in sheath.Sheath can be suitable Slideway straight line, it is also possible to be along slideway curved arrangement；Flexible rack is to use a steel wire by certain pitch at steel Be fastened outside silk flexible axle formation flexible axle tooth bar；Flexible rack also can be had hole, garden by many centres, with hole, garden as axle, with having The curve that profit becomes profile of tooth pierces on flexible ropy around the revolving body that axle scanning in hole, garden is formed so that it is every couples and formed Flexible axle tooth bar；Flexible rack may be used without plastics and makes；Sheath is hard form matter, is metal or plastics.Engage with driver gear One section of flexible shroud is had to overlap outside the flexible rack at the flexible rack two ends at place.So drive assembly just can arbitrarily be arranged.Due to The slideway of outer sliding door is bending, and sheath just can be along slideway curved arrangement, and sliding door connector is owing to being connected in flexible tooth On bar, and flexible rack can only be drive in sheath and be moved back and forth, and then the commutation of motor drives sliding door to move back and forth out Close car door.Men Bingke along bending track show into.

Beneficial effect:

Compared with prior art, the drive mechanism employing flexible rack of the present invention can bend in sheath and run back and forth, and passes through Along the arrangement of outer sliding door slideway, and driving gear beyond slideway, than existing track train, outer sliding door drives such scheme Dynamic mechanism technology is simple, decreases and too fat to move shows mechanism and upper and lower lazy-tongs；With the outer sliding door cable pulley type using on car Drive mechanism ratio, cable pulley type drive mechanism steel cable must be that closed loop connects ability transmission, and to other mechanism (such as glass lifting Device mechanism) there is interference, occupy, be difficult to arrange, and thin steel rope runs with track friction at turning, and the present invention Scheme gear drive flexible rack, arrangement is the unidirectional arrangement along slideway, and drives gear parts logical beyond running slideway Crossing flexible shroud to flexibly connect, depending on length can be because of needs, therefore, the motor driving volume maximum with driving gear is Connected by single flexible sheath, it is possible to be optionally arranged in any suitable position, it solve difficult arrangement on vehicle body Problem.The seizing wire sectional area driving much larger than cable pulley type due to flexible rack sectional area, when therefore this programme drives and turns The seizing wire pressure that pressure at friction drives far below cable pulley type, the frictional force of so every is small, and cable pulley type drives Seizing wire be to form with many tiny steel wire windings, break a finer wire when friction, whole steel cable will quickly be scrapped, Loss of function.This scheme is especially suitable to car.

Detailed description of the invention

As a example by implementing the outer sliding door of motor bus list fan:

As shown in Figure 1, Figure 2, Figure 3 shows, outer sliding door is by upper, middle and lower three band cambered way by sliding door by sliding door even Fitting and each roller trolley constrain on vehicle body, and door can be shown with slideway and slide to the outer side of vehicle body, it is also possible to put into pass with slideway On, develop with vehicle body.Drive mechanism assembly is arranged on glide path.Flexible rack is placed in the protective metal shell of tubulose, sheath edge Glide path and arrange and fix with glide path, in the range of sliding door connector runs, sheath has one along length side To open slot, sliding door connector fixed P at flexible rack by the open slot on sheath and is connected, and driver gear is logical Crossing its gear shaft to be coupled and fixed on vehicle body, and engaging with flexible rack, flexible rack is to use a steel wire by certain spiral shell Away from the formation flexible axle tooth bar that is fastened outside Bowden cable；Flexible rack can be moved back and forth by drive in sheath, so with regard to energy Sliding door is driven to show unlatching, put into closedown.There is one section of flexible shroud set outside the flexible rack at the two ends of driver gear engagement place ?.Drive mechanism assembly is thus facilitated to be arranged into suitable any position according to the situation of vehicle body.As position allows driving machine Structure assembly also can directly with slideway at protective metal shell be fixed together, save between flexible shroud.

Flexible rack can use steel cable to couple with steel ball in centre-drilling hole and form, and gear just uses corresponding circle-arc tooth.

Flexible rack can be formed by wear-resistant plastic such as nylon injection-molding makes it have some flexible.

Sheath can be processed by steel plate roll-forming, it is also possible to forms with plastic injection.
