Abstract

The utility model is a protector for the rear portion of a truck. The protector comprises a crashproof bar and a bracing frame, which are each provided with a reinforced rib and connected together through fasteners. The bracing frame and the reinforced ribs are made of channel steels, and a rubber pad may be arranged between the crashproof bar and the bracing frame. The protector has the advantages of simple structure, less parts, low manufacture cost, and easy installation. It is proved that the protector has excellent crashproof effects when a rear collision between the truck and a car, and can effectively prevent the car running under the truck, thereby protecting people in the car involved in the rear collision.

Description

The motor vehicle rear protective device
Technical field
The utility model relates to a kind of self-propelled vehicle safety device that is fit to be installed on the lorry afterbody.
Background technology
According to the regulation of China relevant department, for safe requirement, prevent that dilly from when knocking into the back traffic accident with lorry, avoiding the generation of pernicious traffic accident, at the lorry afterbody protective device must be installed.Lorry afterbody anticollision device of the prior art also has different frame modes, the following problem is arranged usually, perhaps complex structure, cause producing increase with use cost, perhaps there is certain defective in the design, therefore crashworthiness and insufficient strength when dolly rear-end impact accident takes place, still may cause more serious consequence.
Summary of the invention
The purpose of this utility model is at the deficiencies in the prior art, design a kind of simple in structure, the motor vehicle rear protective device that crashproof intensity is big.
Technical solution of the present utility model is, is that major part constitutes by buffer arm, bracing frame, is provided with reinforced rib on crash bar and bracing frame, between buffer arm and the bracing frame, connects together with securing device, and bracing frame is fixed on the car body.
The said motor vehicle rear protective device of the utility model is simple in structure, and parts are few, and low cost of manufacture is installed simple.Through evidence, the said motor vehicle rear protective device of the utility model has the effect above other anticollision devices behind the roadlice bump that knocks into the back, can stop effectively that roadlice enters below the lorry, plays the effect of protecting personnel's life in the vehicle that knocks into the back.

Fig. 2: A-A is to the view scheme drawing among Fig. 1;
Fig. 3: the bracing frame scheme drawing of channel-section steel structure;
Fig. 4: buffer arm A is to the view scheme drawing;
Fig. 5: two of motor vehicle rear protective device structural representation.
The specific embodiment
Fig. 1 is one of the said motor vehicle rear protective device of a utility model structure scheme drawing.Mainly be by buffer arm, bracing frame combination are formed.Buffer arm 1 connects together with the end face 4 usefulness securing devices 7 of bracing frame 2, is provided with reinforced rib 3 on crash bar 1 and bracing frame 2, and bracing frame 2 is fixed by bolts on the car body, and said bracing frame 2 can be the T-shape structure.On bracing frame 2, can be provided with the hole (not drawing among the figure) that is connected and fixed with car body; Between buffer arm 1 and bracing frame 2, rubber pad 5 can be set.The effect of rubber pad 5, the one, can increase the friction force between buffer arm 1 and the bracing frame 2, guarantee the good combination between the two; The 2nd, can reduce the impact noise between the workpiece effectively; The 3rd, can play the effect of buffering, alleviate the degree of damage that self-propelled vehicle knocks into the back and clashes into.
Fig. 2 is that A-A has provided the scheme drawing of reinforced rib 3 structures on the bracing frame 2 to view among Fig. 1.In fact, be not only said bracing frame 2, on its said crash bar 1, same reinforced rib 3 ' (as shown in Figure 4) can be set also.This is arranged on the reinforced rib on bracing frame and the crash bar, can improve the ability that the motor vehicle tail crash bar withstands shocks greatly.
Fig. 3 has provided a kind of structural representation that utilizes channel-section steel as bracing frame.Because being, crash bar and bracing frame have certain thickness material, to stamp out reinforced rib in the above and on technology and equipment, need corresponding facility with sufficient intensity, so also can utilize channel-section steel as bracing frame 1, on T-shape end face 4, be provided with the hole 6 of settling securing device 7.Can possess the protective device that be fit to impact requires equally, shown in the scheme drawing of the bracing frame 2 on the left side among Fig. 5.
Fig. 4 is that the A of buffer arm is to view.In this scheme drawing, represented on crash bar 1, also to be provided with reinforced rib 3 '.On buffer arm 1, can be provided with the hole 6 ' of settling securing device 7.
Fig. 5 is a kind of motor vehicle rear protective device structure that rubber pad is not set between the end face 4 of buffer arm 1 and bracing frame 2.Between the end face 4 of buffer arm 1 and bracing frame 2, both can connect together (as the bracing frame on Fig. 5 right side) with securing device 7 (for example bolt), also can adopt the mode of welding to be fixed together (as the bracing frame on Fig. 5 left side) end face 4 of crash bar 1 and bracing frame 2.
