Abstract
The utility model relates to a prevent that compact car from piercing safeties of big freight train afterbody, the device include frame, energy -absorbing piece, bumper, screw, installing support, spring, the bumper be the variable cross section wave structure who is " (img file='dest_path_image001. TIF'wi='27'he='16' /) " shape, the bumper passes through the fix with screw on the installing support, a plurality of installation scaffold weldment on the frame, the energy -absorbing piece sets up the outside at the bumper with the bumper phase -match, energy -absorbing piece inside is provided with the rigidity that a spring can increase the energy -absorbing piece. The utility model discloses when the device carried out the hauling operation at big freight train, the compact car that prevents that can be fine pierced big freight train afterbody.
Description
Technical field
The utility model belongs to field of automobile safety, is a kind of prevent compact car from boring the safety interlock into big truck tail specifically.
Background technology
Below big truck back crossbeam, the distance of hollow and the rear tread tailstock is excessive, in accident, compact car headstock very easily bores the rear flank portion into big lorry or rear lower space, in addition two car mass discrepancies are big, compact car speed is fast, knocking into the back in process, the front windshield of compact car and roof front portion can directly bump against big truck side afterbody or afterbody. The height of a compact car is at 70 centimetres to 80 centimetres, and big truck tail distance ground is more than 100 centimetres, and this difference of altitude is just the height of officer's head and chest. If big lorry does not prevent compact car from boring the safety interlock bottom lorry, once knock into the back, compact car will creep into big truck chassis, officer's head is stuck between compartment and compact car seat, bearing circle then withstands on front, and driver is easy to be stuck, and probability of surviving is very low. In addition, the trunk possibility of the big lorry of head impact of front-seat navigating mate is very big, serious threat life security.
The safety interlock of big truck back come with some shortcomings at present. After big lorry erection insurance thick stick, crashproof bar, the big truck tail railway carriage or compartment ground clearance diminishes, being reduced by property of vehicle, for some for loading and unloading the vehicle of goods, load and unload goods time very inconvenient, if walking road conditions, handling environment not good, collision bumper also be easy to damage; The height on big truck back distance ground is big, and trailing wheel is also very big to the distance of the tailstock, if the proceeds posterolateral generation shock accident of compact car and big lorry, compact car very easily enters the afterbody of big lorry from the rear flank drill with ferrule of big lorry, the safety interlock having at present can only stop compact car to bore at the bottom of car from the right astern of big lorry, if clashed into from proceeds posterolateral, then can not play the effect of protection. Obviously, existing safety interlock can not meet present demand, selects a kind of compact car that is possible to prevent to bore the safety interlock into big truck tail, seems very important.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art; a kind of compact car that is possible to prevent is provided to bore the safety interlock into big truck tail; this device is when big lorry carries out transport operation; can well prevent compact car from boring into big truck tail, structure is simple, easy accessibility can realizing inhale can, proceeds posterolateral and rear knock into the back anti-drilling enter multi-faceted protection at the bottom of car.
The purpose of this utility model realizes like this, and this device comprises vehicle frame, energy absorbent block, collision bumper, screw, mounting bracket, spring; Described collision bumper be in "" the variable cross-section wave structure of shape; collision bumper is fixed by screws on mounting bracket; multiple mounting bracket is welded on vehicle frame, and described energy absorbent block mates the outside being arranged on collision bumper mutually with collision bumper, and described energy absorbent block inside is provided with the rigidity that 10 springs can increase energy absorbent block.
Described energy absorbent block is welded by the steel plate that rigidity is less, inner hollow, and energy absorbent block internal welding is equipped with spring, when there is minor impact accident, if energy absorbent block is damaged, only needs to change separately energy absorbent block.
The utility model has the advantage of:
1, the utility model safety interlock are when big lorry carries out transport operation, can well prevent compact car from boring into big truck tail.
2, in the utility model, collision bumper is agent structure, collision bumper be in "" the variable cross-section wave structure of shape, it is to increase the supporting capacity of structure, not easily it is out of shape, it is possible to well stop compact car to bore at the bottom of big lorry car.
3, the additional energy absorbent block in the utility model outside, when occurring to clash into, energy absorbent block buffering, inhale can, and energy absorbent block can change separately, it is to increase the economy of this device.
4, starting material used by the utility model, can directly purchase, and are easy to manufacture; The utility model structure is simple, easy accessibility, and can realize inhaling can, proceeds posterolateral and rear knock into the back anti-drilling enter multi-faceted protection at the bottom of car, maintenance cost is low, economical and practical, is convenient to promote.

Fig. 1 is the utility model three-dimensional structure schematic diagram.
Fig. 2 is the plan structure figure of the utility model Fig. 1.
Fig. 3 is the A place amplification assumption diagram of the utility model Fig. 2.
Sequence number in figure: 1, vehicle frame, 2, energy absorbent block, 3, collision bumper, 4, screw, 5 mounting brackets, 6, spring.
Embodiment
In order to the utility model is realized technique means, creation characteristic, reach object and effect is easy to understand, below in conjunction with concrete diagram, set forth the utility model further.
As depicted in figs. 1 and 2, this device comprises vehicle frame 1, energy absorbent block 2, collision bumper 3, screw 4, mounting bracket 5, spring 6; Described collision bumper 3 be in "" the variable cross-section wave structure of shape; collision bumper 3 is fixed on mounting bracket 5 by screw 4; multiple mounting bracket 5 is welded on vehicle frame 1; described energy absorbent block 2 mates, with collision bumper 3 phase, the outside being arranged at collision bumper 3, and described energy absorbent block 2 inside is provided with the rigidity that 10 springs 6 can increase energy absorbent block 2.
Described energy absorbent block 2 is welded by the steel plate that rigidity is less, inner hollow, and energy absorbent block 2 internal welding is equipped with shown in spring 6(accompanying drawing 3), when there is minor impact accident, if energy absorbent block 2 is damaged, only need to change separately energy absorbent block 2.
