Abstract

The utility model relates to a motor vehicle safety protection device with buffering and energy-absorption function that is suitable for being arranged on the tail part of different kinds of truck model. The technical scheme is that the motor vehicle safety protection device of the utility model comprises an anti-collision bar, an energy absorption device, and a support frame; the support frame is fixed on the vehicle body, the energy-absorption device is arranged between the anti-collision bar and the support frame. The motor vehicle safety protection device of the utility model has simple structure, few parts, low production cost, easy installation, and the function and effect of buffering and absorbing impact energy. When the car in rear-end collision bump on the anti-collision bar, the utility model can effectively prevent and block the car from rushing into the underside of the big truck, thereby realizing the function of protecting the life of the people in rear-collision vehicles.

Description

The self-propelled vehicle safety device

Technical field

The utility model relates to a kind of be fit to be installed on multiple different lorry vehicle afterbody, the self-propelled vehicle safety device with buffering energy-absorbing function.

Background technology

Most of truck afterbody of the prior art does not all have anticollision device, and also difficulty is installed protective device, does not more have the function of buffering and energy-absorbing.Therefore, in case when dolly rear-end collision, rear-end impact took place, dolly will directly pierce the goods carrying vehicle bottom and cause the serious injures and deaths of personnel in the dolly.

Summary of the invention

The purpose of this utility model is at the deficiencies in the prior art, be difficult to install unified safety device for solving various lorry afterbodys, and can alleviate when solving vehicle rear-end collision and absorb the part impulsive force that produced and a kind of buffering energy-absorbing type of design-calculated self-propelled vehicle safety device.

Technical solution of the present utility model is, by buffer arm, energy absorbing device, bracing frame is that major part constitutes, the said self-propelled vehicle safety device of the utility model, its bracing frame is fixed on the car body, and energy absorbing device is placed between buffer arm and the bracing frame.

The said self-propelled vehicle safety device of the utility model is simple in structure, and parts are few, and low cost of manufacture is installed simply, has the function and the effect of buffering and absorption impact energy.After the roadlice that knocks into the back strikes buffer arm, can prevent effectively and stop roadlice enter truck below, play the knock into the back effect of personnel's life in the vehicle of protection.

The specific embodiment

Fig. 1 is the said safety device structural representation of the utility model.Bracing frame is fixed by bolts on the car body, and bracing frame 1 can be (as shown in Figure 3) of " Γ " type, also can Shi “ Fu " (as shown in Figure 4) of type can also be (as Fig. 2 and shown in Figure 5) of " H " type.The bolt hole 2 that is connected and fixed with car body is arranged on bracing frame 1, also have and settle and the hole 4 that is connected energy absorbing device 3, buffer arm 5 is placed on the energy absorbing device 3.

Said " Γ " type bracing frame 1 goes for the relatively lower and narrow vehicle (for example crossbeam of relatively small-sized vehicle) in installation site on vehicle body; Said " Fu " type and " ∏ " type bracing frame 1 are applicable to that installation site on vehicle body is than higher and than the vehicle (crossbeam of relatively large-scale vehicle or vehicle frame) of broad.“ Fu " effect of type is because the installation site is higher, for the dolly that prevents to knock into the back pierce cart below, be bent downwardly so bracing frame 1 designed; “ Fu " bracing frame 1 of type also can collaborated design becomes the form of " ∏ " type, as shown in Figure 5.

Said energy absorbing device 3 can be a strong elastic rubber 6, also can be spring 7.If adopt elastic caoutchouc 6, then both can be packet, also can be the cylinder form, can have a hole 9 of wearing bolt 8 therebetween.

The said energy absorbing device 3 of the utility model can be made of different selection schemes, as in Fig. 2, has described the structure of 4 kinds of different energy absorbing devices 3.A kind of is spring structure A; A kind of is powerful rubber structure D; A kind of is the mixed system C of powerful rubber and spring; Also having a kind of is the mixed system B of piston and spring.Spring structure A is installed in it between bracing frame 1 and the buffer arm 5 with the centre of bolt 8 by spring 7; Powerful rubber structure D is provided with a hole 9 in the centre of rubber 6, with bolt 8 it is installed between bracing frame 1 and the buffer arm 5 then; The mixed system C of powerful rubber and spring adds a spring 7 in the hole 9 of rubber 6 centres, be through in the spring with bolt 8 then it is installed between bracing frame 1 and the buffer arm 5 together; The mixed system B of piston and spring is installed in spring 7 in the housing 11, a push rod 12 that is connected mutually with buffer arm 5 or bracing frame 1 is arranged in the bottom of housing 11, when collision happens, this push rod 12 promotes the effect that spring 7 plays energy-absorbing, and housing 11 can be installed on bracing frame 1 or the buffer arm 5 with securing device 13.

Buffer arm 5 is similar to the bumper/spoiler of automobile, cross-sectional shape as shown in Figure 2, its periphery is inside fillet 10, purpose is that the acute angle that prevents buffer arm 5 peripheries brings unexpected damage to bump object or vehicle.

This Unit Installation can be according to the vehicle of different model specification, in the selection of energy absorbing device 3 parts kinds, both can select for use a kind ofly separately, also can adopt two or more form to mix simultaneously and use.Such as adopting powerful rubber structure, adopt spring structure at the middle part of bracing frame 1 at the two ends of bracing frame 1.Be chosen in the punch position on the buffer arm 5, inject by crashproof panel one sides of buffer arm 5 and after string went up energy absorbing device fixed bolt hole 4 on energy absorbing device 3 (for example rubber 6 or spring 7) and the bracing frame 1 and tighten, overall fixed was on other framing member of vehicle crossbeam, chassis frame or vehicle again with bolt 8.
