Description
Technical field
The invention belongs to technical field of transport facilities, and in particular to a kind of scalable carriage body structure of vehicle.
Background technology
Above mentioned vehicle refers mainly to van-type vehicle（Also known as cargo）, it is mainly used for hermetically sealed all kinds of objects of transport
Money, have maneuverability, easy to operate, work efficiency is high, freight volume is big, goods and materials will not scatter and disappear in transit, goods and materials from drenching with rain,
Protective is excellent and space utilization is good and the strong points such as safely.But van-type vehicle is there are well known shortcoming, specifically：By body
Product is relatively large and during bulky cargo entrucking, entrucking efficiency can not reach the requirement of industry, same example of unloading, the problem for
Only at rear portion, enabling is that the van-type vehicle of back pullout (BPO) is especially prominent.Entire carriage body is resolved into two parts, one is in vehicle
The fixation carriage body of chassis forepart, two be the removable carriage body positioned at vehicle chassis rear portion（I.e. aforementioned scalable carriage body）, then
The entrucking of cargo and efficiency of unloading undoubtedly are able to significantly improve and can significantly increase working space for class of jobs compartment.
The technical information of the scalable carriage body about vehicle can be seen in disclosed Chinese patent literature, is typically such as awarded
" Telescopic carriage " that notification number CN201231798Y recommends is weighed, is that trunk is designed as retractable structure, vehicle is unloaded
When, the major part of trunk is retracted in front compartment, on the contrary same example.
More typical " a kind of Telescopic movable vehicle-mounted carriage body " provided such as CN20447264U, by fixed nacelle and work
Dynamic nacelle composition, activity nacelle are fixed on by the U-shaped slideway intersection being fixed on fixed nacelle bottom plate in sealed cabin body,
Nacelle transmission device is set outside sealed cabin body, which, which is bolted, is installed on outside sealed cabin body；
Be hinged with a tailgate in the tail portion of nacelle bottom plate, which is driven by the telescoping mechanism that is fixed on nacelle bottom plate, i.e., by
The automatic telescopic hydraulic cylinder of telescoping mechanism makes tailgate according to tiling is required to be unfolded or pack up and be embedded in activity nacelle after packing up
Tail portion opening closing of the tail portion to activity nacelle（It for details, reference can be made to the 0020th to 27 section of the patent specification）.Patent visitor
It can be fulfilled in sight in the technique effect described in the 0015th to 0017 section of specification, but there are following shortcoming：First, conduct
Moveable carriages（Can telescopic box body, it is the same below）, since its needs continually slides on platform floor（It is mobile）, such as filling
Moveable carriages is made to be moved to towards headstock direction in the state for being stacked set with fixed carriage body, to expose compartment bottom when unloading cargo
The rear portion of plate and facilitate handling goods, and need to make in transportational process moveable carriages towards away from the direction of headstock i.e. towards vehicle
The direction of compartment bottom plate tail portion is back to the state engaged in the rear portion with fixed carriage body, thus before and after moveable carriages side bottom
The support effects that portion is movably supported on the front and rear side of platform floor be one whether considering scalable carriage body structure rationally not
An important factor for can attaching undue importance to one thing to the neglect of the other, however the patent does not provide due enlightenment；Second, the back-and-forth motion due to moveable carriages need to be by
Power-driven mechanism such as the so-called nacelle actuator drives of the patent, thus the movable compartment set using fixing carriage body as carrier
Body transmission mechanism and the structure of power-driven mechanism that is set using the chassis of vehicle as carrier it is reasonable whether and the two
Drive connection relationship is equally to consider an important factor for one of scalable carriage body structure overlooks either of the two, however the patent is equally not
Provide necessary enlightenment；Third, the patent is provided with equipment moving device, the equipment moving device on tailgate（Equipment moving
Trolley）Though there is certain help for handling goods, also inevitably cargo is generated after the completion of loading
Interference effect, and the equipment moving device can also occupy the space of fixed carriage body and moveable carriages.In particular, actually loading and unloading goods
During object, volume is usually taken on the cargo that quality is relatively large by forklift or similar tool, and in loading because of activity
Carriage body is in tends to nestable state with fixed carriage body, and the rear portion of platform floor is open, and then equipment moving device seems instead
As burden and increase complexity and manufacture cost.
For above-mentioned prior art situation, the applicant has made positive and beneficial design, has formd and will be described below
Technical solution and in the case where taking secrecy provision the test center of the applicant carried out computer simulation deduce experiment,
As a result it is proved to be practicable.
