Abstract
An adjustable rear bumper of an automobile relates to the technical field of automobiles, in particular to a rear bumper which can be adjusted to be in a higher position and a lower position, which comprises a horizontally arranged crash barrier (1), a fixing support (3) for connecting with an automobile chassis (2), a hinged support (4) and an action jack (5) for changing the position of the crash barrier (1). The fixing support (3) is vertically fixed at two sides of the bottom at the rear portion of the automobile chassis (2). The part of the hinged support (4) close to the upper portion is hinged to the lower end of the fixing support (3). The crash barrier (2) is fixedly hinged to the lower end of the hinged support (4). Two ends of the action jack (5) are respectively hinged to the rear end of the automobile chassis (3) and the upper end of the hinged support (4). The adjustable rear bumper of the automobile has the advantages of simple structure, low cost and convenience in installing. The adjustable rear bumper is arranged at the tail of automobiles with higher chassises, such as a truck and the like, thereby being capable of reducing casualties and property loss when rear-end collisions happen.
Description
Technical field
The utility model relates to automobile technical field, is specifically related to a kind of rear bumper that is provided with two position adjustables of height.
Background technology
According to Ministry of Public Security's road traffic accident statistics, 450254 of road traffic accidents, death toll 98738 people, wounded or disabled number 469911 people, 18.8 hundred million yuan of direct economic losses took place in China in 2005.Very big in get on the car the knock into the back ratio that accounts for of whole road traffic accident high speed highway, and the proportion that property damage that rear-end collision caused and personal casualty account for is bigger, and rear-end collision is caused in the visible traffic accident property damage and personal casualty are very serious.When particularly car knocked into the back heavy-duty truck, because the chassis of HD truck is higher, car was easy to cut the afterbody of HD truck, directly clashes into the neck of chaufeur and front-row occupant, and safety air bag this moment (SRS) is also powerless.
Summary of the invention
Technical problem to be solved in the utility model is: provide a kind of simple in structure, cost is low, be provided with the height two position adjustables the adjustable rear bumper of automobile.
Technical solution of the present utility model is: it comprise horizontally set bumper frame 1, use with chassis 2 bonded assembly fixed mounts 3, articulated stand 4 and be used to change the displacement cylinder 5 of bumper frame 1 position, described fixed mount 3 vertically is fixed on the both sides of bottom, chassis 2 back, articulated stand 4 is hinged on the lower end of fixed mount 3 in the position near top, described bumper frame 2 is fixed on articulated stand 4 lower ends, and the two ends of displacement cylinder 5 are hinged on the rear end and articulated stand 4 upper ends of chassis 3 respectively.
Technique effect of the present utility model is: it has the low and advantage easy for installation of simple in structure, cost, is installed in the higher vehicle afterbodys in chassis such as lorry, can significantly reduce personal casualty and the property damage of rear-end collision when taking place.

Fig. 3 is the sectional structure chart of the utility model shock absorber.
The specific embodiment
Shown in Fig. 1,2 and 3, it comprise horizontally set bumper frame 1, use with chassis 2 bonded assembly fixed mounts 3, articulated stand 4 and be used to change the displacement cylinder 5 of bumper frame 1 position, displacement cylinder 5 is cylinder or hydraulic actuating cylinder, described fixed mount 3 vertically is fixed on the both sides of bottom, chassis 2 back, articulated stand 4 is hinged on the lower end of fixed mount 3 in the position near top, described bumper frame 2 is fixed on articulated stand 4 lower ends, and the two ends of displacement cylinder 5 are hinged on the rear end and articulated stand 4 upper ends of chassis 3 respectively.During displacement cylinder 5 actions, can make articulated stand 4 carry out conversion, thereby bumper frame 1 is turn to high and low two diverse locations in vertical and two positions of level.Can be connected by cushion rubber between bumper frame 2 and the articulated stand 4.
The upper end of described articulated stand 4 is provided with shock absorber in the outside, shock absorber comprises buffing pad 6, recoil spring 7 and buffering bolt 8, buffing pad 6 is provided with horizontal keyhole and spring base hole, recoil spring 7 places in the spring base hole of buffing pad 6, buffering bolt 8 is through in the keyhole of recoil spring 7 lumen pores and buffing pad 6, the bolt head of buffering bolt 8 front portions and the upper end of articulated stand 4 offset, and the rear portion of buffering bolt 8 has nut.
The rear bumper of HD truck is designed to adjustable rear bumper, can stops car incision autotruck afterbody.When travelling on the road surface of autotruck in frustration, rear bumper is raise, do not influence the departure angle of automobile, because this moment, the speed of a motor vehicle was lower, rear-end collision can not appear; When automobile during at good road surface or running on expressway; bumper/spoiler is turned down; promptly do not influence automobile normal running; can prevent that again car from cutting at a high speed; the protective effect of safety air bag in addition; can significantly reduce personal casualty and property damage, visible HD truck is installed adjustable rear bumper and is had positive meaning.
