Abstract
The utility model discloses a novel plunge resistant protective device on the back of a truck. The novel plunge resistant protective device on the back of the truck comprises a guard plate and a connecting support, wherein the guard plate is installed on the tail portion of a truck framework through the connecting support, the outer side of the guard plate is provided with a rubber layer, and the guard plate and the connecting support are connected through a connecting rod and an elastic component. Besides, the connecting rod and the support, the connecting rod and the guard plate, and the guard and the elastic component all are hinged through a pin shaft. A limited block is arranged on the connecting support. The novel plunge resistant protective device not only plays a role in preventing a car from plunging into the back portion of the truck, but also utilizes the self energy absorption character of the elastic component and rubber and the characteristic that only rotational motion can be achieved through connections with the pin shafts, thereby beneficially guiding and resolving an impact force from a rear-ending car, and therefore the protective effect for the rear-ending car can be achieved, damage to the rear-ending car can be reduced, and at the same time, the damage of truck chassis parts caused by the car can be prevented.
Description
Technical field
The utility model relates to a kind of, belongs to car load passive security field.
Background technology
Because truck chassis exceeds much than entire car height, when car and the place ahead truck generation rear-end collision, mostly is that car and passengers inside the car are caused serious injury.In order to ensure the safety of driving the user of other vehicles on the road, a lot of truck manufacturing companies all are that Anti-drilling device has been made at the car rear portion.The anti-drilling fender guard in rear portion that uses at present have fixing or folding two kinds select the dress form; this kind structure can only play and prevent that car from piercing the effect at truck rear portion, still can cause serious injury the vehicle that knocks into the back but can not play the effect that relaxes energy-absorbing to the impact of car.
Summary of the invention
Technical problem to be solved in the utility model is for the deficiencies in the prior art, provides a kind of and can effectively relax and reduce from anti-drilling fender guard behind the Novel truck of car impact.
For solving this technical matters; the utility model provides anti-drilling fender guard behind a kind of Novel truck; comprise guar plate and connection bracket; described guar plate is installed on the vehicle frame afterbody by connection bracket; the arranged outside of described guar plate has rubber layer; be connected with elastic element by connecting rod between this guar plate and the connection bracket, between described connecting rod and support and the guar plate, all hinged by bearing pin between guar plate and the elastic element.
Also be provided with limiting stopper on the described connection bracket.
Beneficial effect: the utility model not only plays and prevents that car from piercing the effect at truck rear portion; the own energy absorption characteristics that also takes full advantage of elastic element, rubber is connected the characteristics that can only rotatablely move and carries out favourable guiding decomposition from the impulsive force of the car that knocks into the back with bearing pin; thereby car plays a protective role to knocking into the back; reduction also can avoid the truck chassis parts to be damaged by car simultaneously to the injury of the car that knocks into the back.
Description of drawings
Fig. 1 is structural representation front view of the present utility model;
Fig. 2 is structural representation left view of the present utility model;
Fig. 3 is impact simulation design sketch of the present utility model.
Among the figure: 1 vehicle frame afterbody, 2 connection brackets, 3 connecting rods, 4 guar plates, 5 elastic elements, 6 bearing pins, 7 limiting stoppers.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is done specific descriptions.
Figure 1 shows that structural representation front view of the present utility model.
Figure 2 shows that structural representation left view of the present utility model.
The utility model provides anti-drilling fender guard behind a kind of Novel truck, comprises guar plate 4 and connection bracket 2, and described guar plate 4 is installed on the vehicle frame afterbody 1 by connection bracket 2.
The arranged outside of described guar plate 4 has rubber layer, is connected with elastic element by connecting rod 3 between this guar plate 4 and the connection bracket 2 to be connected, between described connecting rod 3 and support 3 and the guar plate 4, all hinged by bearing pin 6 between guar plate 4 and the elastic element 2.
For guaranteeing safe handling of the present utility model, be provided with limiting stopper 7 on the described connection bracket 2, prevent that elastic element 5 from losing anti-drilling protective effect.
Figure 3 shows that impact simulation design sketch of the present utility model.
When rear-end collision occured, front vehicle contact with guar plate with rubber first, and the effective minimizing of energy-absorbing buffering characteristic that utilizes rubber is to the knock into the back injury of vehicle of rear, and when reaching the limit of along with the rubber energy-absorbing, the elastic element of vehicle frame both sides begins to work.
When the rubber of elastic element 5 and guar plate 4 carries out energy-absorbing, each parts is rotated motion by bearing pin 6 connections, to be decomposed into from the impulsive force of the car that knocks into the back F1 and F2(to the injury of front vehicle mainly from F2), thereby effectively reduced car is injured.
Thereby the utility model utilizes the own energy absorption characteristics of elastic element, rubber to be connected the characteristics that can only rotatablely move with bearing pin to carry out the impulsive force that favourable guiding decomposes from the car that knocks into the back the car that knocks into the back is played a protective role, and also can avoid the truck chassis parts to be damaged by car simultaneously.
The utility model not only plays and prevents that car from piercing the effect at truck rear portion, can also effectively relax the effect of playing energy-absorbing from the impact of car, reduces the injury to the car that knocks into the back, and avoids simultaneously the strength member such as truck chassis drive axle damaged.
The above-mentioned embodiment of the utility model, just casehistory is not only, all in the utility model scope or the change that is equal in the scope of the present utility model all surrounded by the utility model.
