Description
Technical field
The utility model relates to a kind of rear space of scalable envelope and expands caravan, applicable to the design of caravan voluntarily and the manufacturing of various models.
Background technology
The caravan voluntarily of producing and using both at home and abroad at present, structurally general envelope space is all immutable, or the envelope spatial variations wastes time and energy; Performance is stable inadequately, expands the electric pushrod promotion that envelope uses like big multi-expansion, and it causes the envelope sway asynchronous easily; And cause flexible expanding envelope and fixedly envelope is stuck, and in dead battery or electric pushrod damages the back envelope just can't be regained, only suitable re-using when resting in the campsite for a long time expanded space; So just occurred going for a drive, of short duration when curb parking, there are not enough spaces to have a rest in the car; Open the muscle power of losing time again of expanding space, cumbersome.
Existing caravan mostly adopts bigger passenger vehicle of vehicle or box-body truck repacking; Have living space in the car and can be used for carrying out the designing car interior trim; Like number of patent application is 02229334 application " trailed length adjustable modified passenger struck for living ", and the technical scheme of announcing in this patent documentation is: be employed in and hydraulic gear is installed on the chassis is driven telescopic left and right sides envelope and enlarge the usable floor area in the caravan.Its advantage is that area is big, the space is spacious, and not enough is, and the automobile integral structure changes influences the intensity of vehicle; Be that increase vehicle load, volume should not be made self-driving travelling car greatly in addition.
Application at number of patent application 01254800; " a kind of railway carriage or compartment holds variable caravan "; During the technical scheme announced in this patent documentation: envelope stretches backward after being employed in the chassis afterbody and hydraulic gear is installed is driven telescopic air sac, extensilely is limited in scope, has high input, efficient is low, heat insulation effect is poor, uses is dangerous and the shortage value of service.
The purpose of the utility model is the back expansion caravan that manufactures and designs a kind of convenient and swift, Stability Analysis of Structures, safe and reliable, scalable envelope; Convenient and swift being in caravan is being traveled the way; Both can sufficient activity space have been arranged the time, have a spaciousness, comfortable resting space in the time of also can stopping at any time easily in driving.Stable being through motor drives gear pipe link; Left and right sides gear is rotated synchronously, and flexible envelope sway is synchronous, stuck phenomenon can not occur; And in place away from the urban district; Caravan does not have under electricity or the damaged situation of electrical motor, can use the light flexible back of manual pulling to expand envelope, and structure is very reliable and stable.Actv. utilizes interior space, has solved the little problem in small-size travelling caravan space, makes tourism and leisure become comfortable, for the travel at one's own expense of family and individual drive travel provide great convenience.
Summary of the invention
For fear of the defective of prior art, the technical scheme that the utility model proposes is summarized as follows:
A kind of rear space of scalable envelope is expanded caravan; It is made up of car chassis (1) and car body (2); Car body (2) is expanded envelope (4) two parts by fixing car body (3) and scalable back and is formed, and fixedly car body (3) is installed on the compartment underframe (5), flexible after expansion envelope upper mounting rail (6); Be fixed on the car body skeleton (11) through bearing (7); The assembling of guide rail (6) and bearing (7), guide rail (6) below have tooth bar (8) and gear (9) the assembling transmission that is installed on the fixing car body (3), and two gears left and right rail under are with being installed in electrical motor (10) on the underframe (5) through gear pipe link (14) drive synchronously.
The rear space of scalable envelope of the present invention is expanded caravan, and guide rail and bearing fixing are installed on the car body skeleton, back expansion envelope upper mounting rail, through bearing fixing on the car body skeleton.
Description of drawings
Below in conjunction with accompanying drawing the utility model is done and to be further described.
Fig. 1 is that the back is expanded the caravan envelope and is and stretches out view entirely
Fig. 2 is that back expansion caravan envelope is full reduced view
Fig. 3 is the A-A cutaway view of Fig. 1
(1) car chassis (2) car body (3) is fixedly expanded envelope (5) underframe (6) guide rail (7) bearing (8) tooth bar (9) gear (10) electrical motor (11) Vehicle body skeleton (12) sofa backrest (13) electrical motor button (14) pipe link in the scalable back of car body (4)
The specific embodiment
According to the utility model shown in the accompanying drawing is on car chassis (1), to have disposed a scalable back to expand envelope (2); Car body (2) is by fixedly car body (3) and flexible back expansion envelope (4) two parts are formed; Fixedly car body skeleton (11) is gone up bearing (7) is installed; Envelope (2) upper mounting rail (6) is expanded in flexible back; Fixedly car body (3) is expanded envelope (2) with flexible back and is joined together through bearing (7), guide rail (6), and there are tooth bar (8) and gear (9) the assembling transmission that is installed on the fixing car body (3) in guide rail (6) below, and two gears left and right rail under are with being installed in electrical motor (10) on the underframe (5) through the synchronous drive of gear pipe link (14).
Implement the utility model is described further through action below in conjunction with accompanying drawing:
Flexible back as shown in Figure 1 is expanded envelope (2) and is the state of stretching entirely, at first digs sofa backrest (12), handles electrical motor button (13) then; Electrical motor (10) driven gear pipe link (14) rotation, left and right sides gear (9) be rotation synchronously also, and gear (9) is expanded tooth bar (8) transmission on the square guide rail (6) under the envelope (2) through being installed in the back; The back expansion casing (2) that will stretch is regained in the car body; Be in full reduced state shown in Figure 2 until caravan, locking can have been driven then.Otherwise after stopping, open latching device, handle electrical motor button (13) counter-rotating, make gear (9) counter-rotating, through tooth bar (8) transmission, the back is expanded envelope (4) and is steadily stretched out, and is the state of stretching entirely until Fig. 1, and the sofa backrest (12) that can fall down obtains a roomy bed.
The utility model when it uses at needs, only need be opened latching device because the slideway that can be used for expanding and light expansion railway carriage or compartment have been used in the car body rear portion, and the switch that touches the button just can reach maximum usage space.When caravan in motion, retract envelope, locked; The rear portion can supply the occupant to be used as sofa to take, and when caravan arrives campsite or Parking rest during the journey, can open latching device; Handle the electrical motor button and open expansion railway carriage or compartment, back, the sofa backrest that falls down, the rear portion promptly becomes roomy double bed.For the occupant provides spacious sleep, activity space; The utility model light in structure constipation is real, and is convenient to use, safe and reliable; Avoiding the occupant to obtain that spacious and comfortful resting space goes to expend time in again, muscle power, is better suited a novel self-propelled travelling caravan.
