Abstract
The invention provides a door ladder for a coach, which comprises multiple steps. The coach is provided with sliding rails; the multiple steps are arranged on the sliding rails through guidance devices, and can slide along the sliding rails; the sliding rails are inclined sliding rails which are arranged on two sides of a vehicle door; the guidance devices are idler wheels which are arranged on the multiple steps; the idler wheels are matched with the sliding rails; and the number of the idle wheels is two on each side generally. The guidance devices can also adopt other modes, such as slide blocks; the multiple steps are connected with a drive device which is a cylinder; a piston rod of the cylinder is connected with the multiple steps through a rotating shaft; and the tail end of the cylinder body is connected with the chassis of the coach through a hinge. The door ladder enables the inclined sliding rail and an integral door ladder to be arranged in the coach, drives the integral door ladder through the cylinder, increases the prior three steps into at least four steps, reduces the height of each step, is convenient for a passenger to get on and off the coach, controls folding and unfolding of the door ladder by the cylinder, and is convenient for use.
Description
Technical field:
The present invention relates to vehicle, relate in particular to delivery passenger's vehicle, particularly a kind of car body is than higher motorcoach and city motor bus, and concrete is door ladder for coach.
Background technology:
At present, the door ladder design of motorcoach and bus is very unreasonable.A door ladder that has motorcoach now generally is made up of three grades of steps, and first step promptly is the automobile interior chassis, because the chassis of passenger vehicle is generally more than 30 centimetres, so upward first step is just very difficult for the passenger.And second step and the 3rd step receive the restriction of automobile under casing height, therefore do also about 30 centimetres, for general passenger, get on or off the bus and all compare difficulty, especially can be for old man and legs and feet inconvenience person, it is difficult with regard to more to get on or off the bus.
Summary of the invention:
The object of the present invention is to provide a kind of door ladder for coach, it is too high and cause the inconvenient technical matters of getting on or off the bus that described this door ladder for coach will solve the door halfpace rank of motorcoach and bus in the prior art.
This door ladder for coach of the present invention is made up of multistage step, wherein; Described motorcoach is provided with slide rail, and said multistage step is arranged on this slide rail through guide piece, and said slide rail is the tilt slide that is installed on the car door of both sides; It is the roller that is installed on the multistage step that there are a horizontal segment, said guide piece in this slide rail upper end, and this roller matches with slide rail; Said multistage step links to each other with an actuating device; Said actuating device is a cylinder, and the piston rod of this cylinder is connected with described multistage door ladder through rotating shaft, and the end of this cylinder block links to each other with the chassis of motorcoach through hinge; Said multistage step constitutes the monolithic door ladder, and this monolithic door ladder is formed by fixedly connecting on step.
Further, the numbers of steps of said monolithic door ladder is at least three rank.
Further, the inner two ends of said slide rail are provided with shock absorber.
Further, the shock absorber at the inner two ends of said slide rail is cushion rubbers.
Further, the shock absorber at the inner two ends of said slide rail is springs.
Principle of work of the present invention is: door ladder for coach of the present invention can slide along the inclined plane of car door both sides through the roller of both sides;, needs door ladder the door ladder of multistage step is slid into the lower end of inclined plane when putting down by air cylinder driven; The step in bottom and the ground-surface height of door ladder are about 22 centimetres; Height between the several steps on the door ladder also is about 22 centimetres simultaneously, and passenger getting on/off is very convenient; When cylinder shrinks, can the door ladder be packed up, car door can be closed.
The present invention compares with prior art, and its effect is actively with tangible.The present invention through air cylinder driven monolithic door ladder, increases at least level Four step with original three grades of steps in that tilt slide and monolithic door ladder is set in motorcoach; Reduced the height of each step; Make things convenient for passenger getting on/off, the expansion of door ladder and packing up by cylinder control, easy to use.
Description of drawings:
Fig. 1 is the scheme drawing of door ladder for coach of the present invention when putting down.
Fig. 2 is the scheme drawing of door ladder for coach of the present invention when packing up.
The specific embodiment:
Embodiment 1:
As depicted in figs. 1 and 2, this door ladder for coach of the present invention is made up of multistage step 3, and wherein, described motorcoach is provided with slide rail, and said multistage step 3 is arranged on this slide rail through guide piece, and this multistage step 3 can slide along slide rail.
Further, said slide rail is the tilt slide 5 that is installed on the both sides car door 6, and there is a horizontal segment these slide rail 5 upper ends; When door ladder 3 is packed up; Horizontal segment on the slide rail 5 can be held a ladder 3, prevents that it from gliding, and said guide piece is the roller 2 that is installed on the multistage step 3; This roller 2 matches with slide rail 5, and the quantity of roller 2 is generally two of sides.This guide piece also can adopt other mode, and such as slide block, the effect of guide piece is that multistage step is moved up and down along the tilting slide rail.
Further, said multistage step 3 links to each other with an actuating device, and this actuating device makes and is that step 3 moves more.
Further, said actuating device is a cylinder 1, and the piston rod of this cylinder 1 is connected with described multistage step 3 through rotating shaft, and the end of this cylinder 1 body links to each other with the chassis 7 of motorcoach through hinge.
Further, said multistage step 3 constitutes monolithic door ladder 3.
Further, the numbers of steps of described monolithic door ladder 3 is at least three rank.Door ladder 3 is opened when the piston rod of cylinder 1 stretches out; Just door ladder 3 moves to the lower end along tilt slide 5, and at this moment, step and bottom surface, compartment 8 on ground 9, the door ladder 3 constitute a level Four step; The height of each grade step is about 22 centimetres like this, makes things convenient for passenger getting on/off; When cylinder 1 shrank, door ladder 3 was packed up, and the one-level step of its top and low side and slide rail 5 justify aligns make things convenient for closed door 6 this moment.
Further, said slide rail 5 inner two ends are provided with shock absorber 4, and when cylinder 1 driving gate ladder 3 launches and packs up when moving to the termination, the roller 2 on the door ladder 3 can slow down impulsive force by shock absorber 4.
Further, the shock absorber 4 at said slide rail 5 inner two ends is cushion rubbers 4, and cushion rubber 4 can be that elastomeric material constitutes, and also can be made up of other padded coaming.
Further, the shock absorber 4 at said slide rail 5 inner two ends is springs.
