Description
Technical field
The present invention relates to door mechanism of flat-headed heavy duty truck.
Background technology
In bogie, " cab-over-engine vehicle " more and more is subjected to people's welcome.This vehicle places the driver's cabin back lower place with motor, and the position reach of driver's cabin, and ground clearance increase make driver's the visual field openr, help safety traffic.Simultaneously, under the identical prerequisite of wheelbase, the cab space of general " cab-over-engine vehicle " is bigger than " normal control vehicle ".Driving environment is better.Though cab-over-engine vehicle has plurality of advantages, existing " tack heavily blocks " compared with " long nose heave card ", its comparatively difficulty of getting on or off the bus.Because the driver's cabin position that tack heavily blocks is higher, if will enter driver's cabin, the driver need climb three steps (pedal) to level Four.And the car door that has " tack heavily blocks " now is also continued to use the structure of traditional car door: the hinge (bearing pin) by vertical installation is one side with being hinged on the vehicle body of car door, during the car door folding, car door is around hinge through, and in the whole process, car door is on same horizontal plane.Two to three pedals have been installed below car door simultaneously, because the cab-over-engine vehicle driver's cabin is liftoff higher, and body width is unanimous between the higher and lower levels, the pedal center line is in same perpendicular, quite require great effort when therefore the driver gets on or off the bus, also have certain potential safety hazard, this does not meet the requirement of automobile ergonomics.
Summary of the invention
For the mode of getting on or off the bus of providing convenience for the flat-headed heavy duty truck driver, the present invention embodies the Automobile Design theory that people-oriented according to the characteristics of flat-headed heavy duty truck, proposes door mechanism of flat-headed heavy duty truck.
The present invention is based on that following inventive concept designs: in daily life, stair activity is very common.This people of making arrives eminence from lower, or arrives the motion mode of lower from eminence, is quite easily for the ordinary people.Associate thus: if the driver gets on or off the bus as stair activity from the frontal of driver's cabin, the so this mode of getting on or off the bus will become very simple and convenient.For this reason, propose a kind of door mechanism of flat-headed heavy duty truck, abandoned original car door and closed and close mode, selected the car door integral translation to close and closed, and between car door and driver's cabin, designed 2～4 grades of pedals, as a flight of stairs, for driver's use of getting on or off the bus.
Instruct according to above-mentioned inventive concept, technical scheme of the present invention is: door mechanism of flat-headed heavy duty truck, comprise car door, it is characterized in that car door takes the folding mode of integral translation with respect to the driver's cabin side, described folding mode is realized by following structure: be hinged with 2～4 grades of pedals on the car door, the other end and the driver's cabin of described pedal are hinged, and described pedal is connected to a motion integral body by linkage, is provided with reset buffer means between driver's cabin and pedal; In opened condition the time, described a plurality of pedals are parallel to the ground at described car door, arrange to the back upper place from the driver's cabin front and form a flight of stairs shape; When described car door was closure state, it is superimposed in the car door inboard that described pedal and connecting rod are essentially vertical shape; Car door is provided with door lock, and the snap close binding site of door lock is in the side of car door.
The course of work summary of described door mechanism of flat-headed heavy duty truck is: when opening car door, open door lock, in driver's cabin to the extrapolation or the door of outside driver's cabin, outwards pulling a cart, under the effect of reset buffer means, pedal is the center of circle with itself and vehicle body pin joint, make circumference and rotate, car door and vehicle body keeping parallelism are done translation stably; When the car door complete opening, pedal is parallel to the ground, and car door links to each other with pedal, and is still parallel with vehicle body.When door closing, driver's cabin push away outside to inside or in driver's cabin first Nei Lachemen, the direction that pedal is opposite is made circular motion, car door earlier in translation, realize door closing; When car door was closed fully, pedal was superimposed in the car door inboard.
Beneficial effect: above-mentioned car door mechanism applies to flat-headed heavy duty truck, does not take the space of driver's cabin, and mechanism is simple, is easy to realize.It has adopted a kind of car door translational opening-closing scheme that also is not applied to up to now on the automobile, fundamentally changed flat-headed heavy duty truck driver's the mode of getting on or off the bus, become to walk to get on the bus by original car of climbing up, make driver's the same convenient, safety with stair activity of getting on or off the bus, it is easily laborsaving to get on or off the bus.This car door mechanism uses simple mechanism to realize purpose, and cost of manufacture is not high; Embody the Automobile Design theory that people-oriented simultaneously, met the requirement of automobile ergonomics fully.
Description of drawings
Fig. 1 is the structural representation (car door opening state) of door mechanism of flat-headed heavy duty truck of the present invention.
Fig. 2 is along the A-A sectional view among Fig. 1.
Fig. 3 is a B portion enlarged drawing among Fig. 1.
Fig. 4 is the front view of car door.
The specific embodiment
As shown in Figure 1, be hinged with three grades of pedals 3 on the car door 1, the other end of described pedal 3 and driver's cabin 2 are hinged, and described pedal 3 is connected to a motion integral body by linkage.Linkage is made up of connecting rod 4, intermediate connecting rod 5, push rod 6.
Between driver's cabin and pedal, be provided with reset buffer means.Shown in Fig. 1,3, be provided with torsion spring 8 in pedal 3 and driver's cabin 2 hinged places, between pedal 3 and driver's cabin 2, be provided with extension spring 7.Torsion spring 8 combines with extension spring 7 and constitutes reset buffer means, uses by the mutual collocation of torsion spring and extension spring car door is become steadily at whole moving process, and the required active force that applies of people is less.Under the lighter situation of car door weight, above-mentioned extension spring 7 can not wanted, and the purpose that torsion spring 8 just can reach the buffering that resets only need be set, and torsion spring 8 is exactly described reset buffer means.If necessary, can consider between car door and driver's cabin to install the unidirectional slow tube of fluid power (cylinder), be allowed to condition at and apply resistance when opening the door and cushion as reset buffer means, inoperative at closing time.
As shown in Figure 1, 2, pedal 3 is parallel to the ground, arrangement forms a flight of stairs shape to the back upper place from driver's cabin 2 fronts, first order pedal is liftoff 380～420 millimeters, second level pedal is 330～370 millimeters from the height of first order pedal, and third level pedal is 280～320 millimeters from the cab floor height.During car door opening, the distance between car door and the driver's cabin side is 580～620 millimeters.When described car door 1 was closure state, it is superimposed in the car door inboard that described pedal 3 and linkage are essentially vertical shape.
As shown in Figure 4, car door 1 is provided with door lock 9, and the snap close binding site 10 of door lock is two, and respectively in the both sides of car door, the assurance car door is reliably locked.
In above-mentioned car door mechanism, air cylinder device can be set between driver's cabin and car door realize opening.
