Abstract
The invention discloses a fold-typed rear bumper, which comprises a rear bumper and a supporting beam, and the rear bumper is fixed on a car frame by the supporting beam, the supporting beam is composed of a fixed upper supporting beam and a reversible lower supporting beam, the lower supporting beam that is turned down combines with the upper supporting beam into the integrated structure, and the lower end of the lower supporting beam is used for fixing the rear bumper. The invention can lead the rear bumper to be folded in bad road condition or when unloading goods, thus avoiding the damage of the rear bumper and having convenient and simple use.
Description
Technical field
The present invention relates to a kind of vehicle rear bumper, relate in particular to a kind of folding rear bumper on the dumping car that is installed in.
Background technology
Dumping car is installed rear bumper at its rear portion usually and is come vehicle is carried out safety guard-safeguard, and existing dumping car rear bumper generally all is to be fixed on the main car frame of chassis.The dumping car work of travelling on the road surface of uneven of being everlasting, rear bumper can and the place collision of bump, cause the damage of rear bumper, in addition, when unloading, goods collides rear bumper easily, also can cause the damage of rear bumper.
Summary of the invention
The technical problem to be solved in the present invention provides a kind of collapsible, folding and unfolding foldaway back bumper easily.
The present invention solves above-mentioned technical matters by the following technical programs: a kind of foldaway back bumper, comprise rear bumper, support beam, rear bumper is fixed on the vehicle frame by support beam, support beam is made of fixing upper support beam, turnover lower support beam, the lower support beam puts down the back and cooperates the formation integrative-structure with the upper support beam, and the lower end of lower support beam is rear bumper fixedly.
Be rotationally connected the joint face corresponding matching unanimity between the two between upper support beam and the lower support beam.
The upper support beam is connected by the hinge that is provided with in the two side with the lower support beam.
The joint face of upper and lower support beam all is a horizontal surface.
Upper and lower support beam is provided with the anchor fitting that the two is fixed into integrative-structure.
The hasp of described anchor fitting for being provided with on support beam therein, that be provided with and suspension member snap fit on another support beam.
Be provided with bump rubber in upper support beam top, bump rubber avoids rear bumper to overturn up and the vehicle frame direct impact.
Bump rubber is fixed on the vehicle frame by stay bearing plate.
The upper support beam is fixed on the vehicle frame by adapter plate.
The present invention adopts foldaway back bumper, turning under the bad situation of road conditions or on when unloading, increased the angle of leaving away of automobile, avoided the rear bumper collision to be damaged, improve the crossing ability of vehicle, satisfied the travel requirement of vehicle in different road conditions in bad road conditions.Upper support beam and lower support beam are to be rotatably connected, after the lower support beam puts down, upper and lower support beam joint face corresponding matching, form the structure of support beam one, played the effect of supporting rear bumper, in the normal vehicle operation process, undertaken fastening by the hasp that is installed on the upper and lower support beam, prevent the rear bumper bob, after the more important thing is that up and down support beam is fastening, upper and lower support beam forms integrative-structure, support rear bumper, guarantee the crashproof function that realizes that rear bumper itself is had.When vehicle is unloaded or travel when the road surface of uneven, can open hasp, upwards folding rear bumper, prevent that the goods or the bump that unload from running into rear bumper, make also that goods is more smooth to be unloaded.The rear bumper top is provided with bump rubber, and when rear bumper overturn up, bump rubber was avoided rear bumper and vehicle frame direct impact, in order to avoid rear bumper or vehicle frame are caused unnecessary damage.After overturning up, rear bumper is fixed on upturned position automatically by self gravitation.Rear bumper can also connect together by chain and back mud flap, when building the road and during the paver coordinating operation, by chain rear mudguard rubber is mentioned, and avoids interfering with paver.The present invention is simple in structure, result of use is outstanding, structural safety is reliable.
Description of drawings
The invention will be further described below in conjunction with drawings and Examples, in the accompanying drawing:
Fig. 1 is the structural representation of the embodiment of the invention;
Fig. 2 is the structural representation when bumper/spoiler is packed up in the embodiment of the invention;
Fig. 3 is the birds-eye view of Fig. 1.
The specific embodiment
As Fig. 1,2, shown in 3, a kind of foldaway back bumper, comprise rear bumper 2, support beam, rear bumper 2 is fixed on the vehicle frame 1 by support beam, support beam is by fixing upper support beam 9, turnover lower support beam 3 constitutes, upper support beam 9 is fixed on the vehicle frame 1 by adapter plate 4, upper support beam 9 is connected by the hinge 8 that is provided with in the two side with lower support beam 3, lower support beam 3 puts down the back and cooperates the formation integrative-structure with upper support beam 9, on, lower support beam 9,3 respectively are provided with two, the lower end of lower support beam 3 is fixed on the rear bumper 2, on, lower support beam 9,3 joint face all is a horizontal surface, by anchor fitting the two is secured together, described anchor fitting is the hasp 10 that is provided with on lower support beam 3, the suspension member 11 that cooperates with hasp 10 that on upper support beam 9, is provided with, hasp 10 is buckled on the suspension member 11 and just will goes up, lower support beam 9,3 is fixing, be provided with bump rubber 6 in upper support beam 9 tops, bump rubber 6 is fixed on the vehicle frame 1 by stay bearing plate 5, when rear bumper 2 upsets are got on, bump rubber 6 is avoided rear bumper 2 and vehicle frame 1 direct impact, in order to avoid rear bumper 2 or vehicle frame 1 are caused unnecessary damage, rear bumper 2 upsets are fixed on upturned position automatically by self gravitation after getting on.
