Abstract

The utility model relates to a vehicle security protecting device which can be arranged at the tail parts of different lorries and have the functions of buffering and absorbing energy. The vehicle security protecting device has the technical proposal as follows: the vehicle security protecting device consists of a bumper, an energy absorbing device and a support bracket which is fixed on the vehicle body, the energy absorbing device is arranged between the bumper and the support bracket, a reinforcing bracket is arranged on the support bracket and the bumper. The vehicle security protecting device of the utility model has simple structure, few parts, low production cost, simple installation, and the functions and effects of buffering and absorbing the impact energy. When a rear-end car runs upon the bumper, the vehicle security protecting device can effectively prevent the car from entering the lower part of the lorry, thereby protecting the personnel life inside the rear-end car.

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.On March 6th, 2007, the applicant applied for a utility model patent " self-propelled vehicle safety device ", number of patent application: 200720083695.X, and this patent can solve the problem that present truck afterbody does not have anticollision device.But on the basis of this patent, can also make further perfect.
Summary of the invention
The purpose of this utility model is at the deficiencies in the prior art, for further improving deficiency of the prior art, solve various lorry afterbodys and be difficult to install unified safety device, 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, is that major part constitutes by buffer arm, energy absorbing device, bracing frame, and its bracing frame is fixed on the car body, and energy absorbing device is placed between buffer arm and the bracing frame.In order to strengthen the intensity of buffer arm both sides bump, in the utility model, on said bracing frame and the buffer arm, be provided with reinforced support, between reinforced support and buffer arm, also can settle energy absorbing device.
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, and its intensity ratio is of the prior art better.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, bracing frame 1 can be (as shown in figures 1 and 3) of " Γ " type, or (as Fig. 2, Fig. 5 and shown in Figure 6) of " Π " type, or reclinate " Γ " type or " Π " type, (“ Fu " type does schematic representation and explanation, as Fig. 4, shown in Figure 5).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.In order to strengthen the intensity of buffer arm 5 both sides bump, on said bracing frame 1 and buffer arm 5, reinforced support 14 is housed, can be A-frame at reinforced support 14, and be mounted with energy absorbing device 3 between the buffer arm 5, as strong elastic rubber 6 (as Fig. 2 and shown in Figure 6).
Said " Γ " type bracing frame 1 is applicable to the relatively lower and narrow vehicle (for example crossbeam of relatively small-sized vehicle) in the installation site on vehicle body; Said " Fu " type and " Π " 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 " Π " type, as shown in Figure 5.
Said energy absorbing device 3 can be a strong elastic rubber 6, or spring 7.If adopt elastic caoutchouc 6, have the hole 9 of wearing bolt 8 therein.
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; 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 porosely 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 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, the 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 such as Fig. 2, shown in Figure 6, and its periphery can be inside fillet 10, and purpose is that the acute angle that prevents buffer arm 5 peripheries brings unexpected damage to bump object or vehicle.What provide among Fig. 6 is a kind ofly on " Π " type bracing frame 1 coherent ennation to be arranged, and with triangle reinforced support 14 structure combining forms, the safety device of this version has better intensity and impact resistant capability.
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, or adopts two or more form to mix simultaneously and uses.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.
