Description

A kind of camping car spatial extension jack

Technical field

The utility model relates to encamps or the travel equipment field, is meant a kind of camping car spatial extension jack especially.

Background technology

The common space of existing camping car is less, is difficult to satisfy people's camping needs, and if add large space and will make that the camping car volume is bigger, be difficult in the hill walking, and infeasible, in order to solve this difficult problem, people have proposed various solutions.

As Chinese patent CN2654430Y a kind of " este wagon combined tent bed " proposed, be on the floor level of the tailstock, postpone connecting bed board with axle, the tail end of bed board and tent bracket fastening, the upper end of tent bracket is connected with axle with an end of tent upper frame, and the other end of tent upper frame is connected with the following axle of continuing to use of the tailstock door of propping up.From tailstock portion to tent bracket, the housing plane that constitutes of tent upper frame all hidden tarpaulin.This patent reaches the purpose that enlarges the space, compartment by add tent bed at the tailstock, but because it separates with vehicle body, no matter carry, assemble or all comparatively inconvenience of folding, is difficult to satisfy people's actual demand.

And for example Chinese patent CN2199087Y has proposed a kind of " outdoor hotel RV recreational vehicle ", constituted by car body, bracing or strutting arrangement, top system device and Pneumatic controller, be arranged in the car body by each compartment, utilize Pneumatic controller inwardly, each compartment of outer displacement, utilize guide rod and each compartment after the strut bar held in tension of bracing or strutting arrangement and utilize top system device to make the flat attitude of back interior compartment that stretches, thereby increase the space, compartment.This patent adopts all-in-one-piece casing to move the purpose that realizes increasing the space, compartment, and bigger to the change of car body, cost is higher, and it is bigger to fold rear space, and impracticable.

Chinese patent CN2743176Y has proposed a kind of " can expand vehicle body formula lodging vehicle " for another example, it comprises the vehicle body of installing on the car chassis, the vehicle body both sides are outwardly directed telescopic action vehicle body, the telescopic action vehicle body is connected with transmission device, transmission device is connected with actuating unit, and the telescopic action body bottom is provided with track.This patent is same to be existed greatlyyer to the change of car body, and cost is higher, and it is bigger to fold rear space, and unpractical shortcoming.

The utility model content

Main purpose of the present utility model is to overcome the less shortcoming in camping car space in the prior art, and a kind of camping car spatial extension jack is provided, and it can reach maximum expansion space with the space that folds of minimum.

The utility model adopts following technical scheme:

A kind of camping car spatial extension jack, it comprises a top board, a wallboard and a floor, and the forward edge of this top board is articulated on the top doorframe of camping car rear end, and the rear side of this top board is provided with a hook; This wallboard is provided with a box fastener, this box fastener have one with the suitable hanging hole of this hook, the lower edge of this wallboard is articulated in the posterior edges on this floor, the forward edge on this floor is articulated on the below doorframe of camping car rear end.

According to a better embodiment of the present utility model, when complete deployed condition, the front side of described top board is higher than the rear side of this top board.

According to a better embodiment of the present utility model, when complete deployed condition, described floor is in horizontality.

According to a better embodiment of the present utility model, when complete deployed condition, described wallboard is in vertical state.

According to a better embodiment of the present utility model, the left and right sides of this jack seals with waterproof case, forms a confined space.

According to a better embodiment of the present utility model, described waterproof case is plastic flagstone or canvas.

By above-mentioned to description of the present utility model as can be known, compared with prior art, a kind of camping car spatial extension jack of the present utility model has following advantage:

One, the utility model utilizes and articulates between top board, wallboard and the floor and cooperating of rotating, and produces the bigger wider space of camping car with the less space that folds, and has solved the less difficult problem in camping car space in the prior art;

Two, top board is articulated on the top doorframe of camping car rear end, and the floor is articulated on the below doorframe of camping car rear end, makes whole jack of the present utility model and vehicle body become one structure, be communicated with vehicle interior space upon deployment, extend the space, compartment, folded the tail gate of back top board as vehicle, wallboard, the adjacent top board in floor, the space that takies in the compartment is minimum, and owing to be structure as a whole with vehicle body, need not to carry separately, it is extremely convenient to use;

Three, the utility model is changed less to existing vehicle, does not influence the integraty of original chassis structure of car load, can not produce the solid problem of protecting, and it is lower to change cost;

Four, the utility model is simple in structure, and parts such as sheet material, hinge, box fastener, hook are all obtained easily, and processing is simple, and is easy to assembly, is beneficial to the industrialization volume production;

Five, the utility model is when complete deployed condition, and the front side of top board is higher than the rear side of top board, can make the structure after the utility model launches comparatively firm on the one hand, fold more simply, rainwater is taken advantage of a situation stay, seeping phenomenon can not occur;

Six, the utility model is when complete deployed condition, and the floor is in horizontality, and wallboard is in vertical state, can make the structure after the utility model launches comparatively firm, reliable;

In a word, the utility model is by sliding between top board, wallboard and the floor and cooperating of rotating, produce the bigger wider space of camping car with the less space that folds, solved the less difficult problem in camping car space in the prior art, and assembling is simple, productive costs is lower, and the use that is worth promoting has good market outlook.
