In addition, existing step usually only for simply packing up or putting down, cannot can also be accommodated in confined space by a pulling force or thrust, therefore be difficult to the scalable ladder realizing automatic control type on car body while realization is packed up or put down.
Summary of the invention:
Object of the present invention is exactly to solve existing issue, and a kind of vehicle-mounted built-in scalable ladder is provided, can directly be installed in car body, add usable area in car and overall for closed, not by ectocine, safe and reliable, can automatic telescopic be realized and automatic accomodation in casing, cover plate makes it very firm as support.
Technology solution of the present invention is as follows:
A kind of vehicle-mounted built-in scalable ladder, comprise: tread structure and be positioned at car body car door below casing, this tread structure can be accommodated in described casing when deflated, and can extend to ground from the opening of described casing is stepped when extended, described tread structure comprises:
Cover plate, is articulated with on the base of described opening;
Two row parallelogram linkages, are connected to each other by multiple connecting rod paralleled with ground, and the lower end of described parallelogram linkage is articulated and connected on the inside face of described cover plate;
At least one step plate, each step plate is between described two row parallelogram linkages and be articulated with on described connecting rod;
Upper guide plate and lower guide plate, be articulated and connected the step plate two ends respectively adjacent in the described step plate two ends and below thereof that are positioned at top, and described upper guide plate and lower guide plate are articulated and connected each other and simultaneously arrange described parallelogram linkage upper end thereof with each and be connected, described lower guide plate bottom is articulated and connected on the sidewall of described opening; And
Electricity cylinder, be positioned at described casing, one end is articulated and connected in the back side of the step plate being positioned at top, and the other end is connected on the inwall of described casing.
As preferably, described upper guide plate and lower guide plate are triangle aluminium alloy plate, and upper guide plate and lower guide plate are all positioned at the outside of parallelogram linkage.
As preferably, described cover inner surface is symmetrically fixed with stirrup and L-type fixed plate, and described L-type fixed plate is hingedly connected with pipe link, and described pipe link and parallelogram linkage are articulated and connected.
Beneficial effect of the present invention is:
Integral structure of the present invention can directly be installed in space reserved below vehicle body side car door, add the usable area of vehicle-mounted inside and overall for closed, avoid by extraneous collision damage or adverse weather conditions, guarantee safe and reliable, adopting electric cylinder and parallelogram linkage to make to mark time can automatic deploying and retracting, add guide plate and lower guide plate simultaneously, make tread structure while folding and unfolding by guide plate and lower guide plate realize being accommodated in casing after it rotates, overall easy to use, and cover plate makes it very firm as support.
Accompanying drawing illustrates:

Fig. 2 is structure rounding state schematic diagram of the present invention.
In figure: 1, car body; 2, casing; 3, cover plate; 4, parallelogram linkage; 5, step plate; 6, electric cylinder; 7, upper guide plate; 8, lower guide plate; 9, stirrup; 10, L-type fixed plate; 11, pipe link.
Detailed description of the invention:
As shown in Figure 1-2, a kind of vehicle-mounted built-in scalable ladder, comprise: tread structure and be positioned at car body 1 car door below casing 2, this tread structure can be accommodated in described casing 2 when deflated, can extend to ground from the opening of described casing 2 is stepped when extended, described tread structure comprises:
Cover plate 3, is articulated with on the base of described opening;
Two row parallelogram linkages 4, are connected to each other by multiple connecting rod paralleled with ground, and the lower end of described parallelogram linkage 4 is articulated and connected on the inside face of described cover plate 3;
At least one step plate 5, each step plate 5 is between described two row parallelogram linkages 4 and be articulated with on described connecting rod;
Upper guide plate 7 and lower guide plate 8, be articulated and connected step plate 5 two ends respectively adjacent in described step plate 5 two ends and below thereof that are positioned at top, and described upper guide plate 7 and lower guide plate 8 are articulated and connected each other and simultaneously arrange described parallelogram linkage 4 upper end thereof with each and be connected, described lower guide plate 8 bottom is articulated and connected on the sidewall of described opening; And
Electricity cylinder 6, be positioned at described casing 2, one end is articulated and connected in the back side of the step plate 5 being positioned at top, and the other end is connected on the inwall of described casing 2.
Particularly, described upper guide plate 7 is triangle aluminium alloy plate with lower guide plate 8, and upper guide plate 7 and lower guide plate 8 are all positioned at the outside of parallelogram linkage 4.
Particularly, described cover plate 3 inside face is symmetrically fixed with stirrup 9 and L-type fixed plate 10, and described L-type fixed plate 10 is hingedly connected with pipe link 11, and described pipe link 11 is articulated and connected with parallelogram linkage 4.
Principle of work of the present invention is: electric cylinder 6 controls its work by control circuit, when electric cylinder 6 push rod draws in, the step plate 5 at top is driven to drive it to rotate by upper guide plate 7, the hinge-point be now connected between above guide plate 7 with lower guide plate 8 is fulcrum, the step plate 5 at top drives the step plate 5 of below to draw in by the parallelogram linkage 4 at two ends simultaneously, overall following guide plate 8 is that fulcrum inwardly rotates with the hinge-point that opening sidewalls is connected, until cover plate 3 compresses casing 2 opening part, when electric cylinder 6 push rod is extrapolated, upper guide plate 7 and lower guide plate 8 outwards rotate, the step plate 5 at top drives it upwards to rotate by upper guide plate 7 simultaneously, the step plate 5 at top drives the step plate 5 of below to launch until step plate 5 is in level attitude state by the parallelogram linkage 4 at two ends, its using state i.e., this vehicle-mounted built-in scalable ladder can directly be installed in car body, add usable area in car and overall for closed, not by ectocine, safe and reliable, can automatic telescopic be realized and automatic accomodation in casing 2, cover plate makes it very firm as support.
The foregoing is only preferred embodiment of the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, should belong to the scope of protection of the invention.
