Abstract

The utility model relates to a vehicle bumper, mainly relating to a safe suspension bracket for the rear end of a truck suffering from a car collision. The utility model is mainly composed of two fixing brackets, two suspension rods, an upper and a lower horizontal ring tubes, and an outer tube, wherein, the upper ends of the vertical planes of the two fixing brackets are respectively pivoted with the upper ends of the two suspension rods correspondingly; the front tubes of the upper and the lower horizontal ring tubes are connected with the lower ends of the two suspension rods which are lower than the fixing brackets; while the rear tubes of the upper and the lower horizontal ring tubes are connected with an external layer tube simultaneously; the middle and lateral parts of the front and the rear tubes of the upper and the lower horizontal ring tubes are respectively connected with a pagoda layer tube and a stacked tube. As a result, the car collisions with trucks can be prevented so that the loss of collisions can be reduced.

Description

The anti-safe hanger that knocks into the back of truck

The utility model relates to a kind of anticollision device for vehicle, mainly refers to the safe hanger of the small passenger car collision truck tailstock.

At present, the most of highway of China still is small passenger car and truck all-purpose road, is easy to occur the small passenger car truck that knocks into the back, and collide traffic accident accident bottom the truck, but up to now, the truck tailstock does not also have setting to prevent the safeguard construction that car knocks into the back.

In view of this, the purpose of this utility model provides and a kind ofly articulates the tubular construction hanger that suspention has certain rigidity at the truck afterbody, prevents the small passenger car truck that knocks into the back, and pierces the traffic accident bottom the truck.

The purpose of this utility model is achieved in that it mainly is to be made of two fixed mounts, two suspending rod, upper and lower horizontal endless tube and an outer tube, wherein the back vertical plane upper end of two fixed mounts articulates corresponding two suspending rod upper end respectively, upper and lower horizontal endless tube is the upper and lower parallel flat endless tube of level and all is connected the two suspending rod lower ends that are lower than fixed mount with its front tube, and the rear tube of upper and lower horizontal endless tube connects an outer tube simultaneously, and the centre portion between the forward and backward side pipe of upper and lower horizontal endless tube is connected pagoda layer pipe and stacked tube all respectively with the both sides part.

Above-mentioned outer tube is the channel pipe structure.

Above-mentioned pagoda layer pipe is three layers of pipe that the front side is long, rear side is short, and above-mentioned stacked tube is three layers of identical pipe of length.

Owing to adopt such scheme: prevent that not only the collision ability is strong, and prevent that car from piercing the truck bottom,, also can adapt to the road surface that is uneven and use though this hanger position is low simultaneously.

Below in conjunction with drawings and Examples the utility model is further specified.

Fig. 1 the utility model exemplary embodiments front elevational schematic.

Fig. 2 the utility model exemplary embodiments schematic side view.

Fig. 3 the utility model exemplary embodiments schematic top plan view.

Among the figure: 1, fixed mount 2, suspending rod 3, last horizontal endless tube 31, pagoda layer pipe 32, stacked tube 4, following horizontal endless tube 41, pagoda layer pipe 42, stacked tube 5, outer tube

Present embodiment mainly is made of two fixed mounts 1, two suspending rod 2, last horizontal endless tube 3, following horizontal endless tube 4 and outer tube 5, as Figure 1-3, and wherein:

Two fixed mounts 1 are the angle-iron frames that is connected truck crossbeam both sides with screw or bolt, and the vertical plane upper end has pin shaft hole thereafter.

Two suspending rod 2 are to be articulated in abreast in the pin shaft hole of two fixed mounts 1 respectively by two channel-section steel upper ends, and suspend in midair naturally its lower end.

Going up horizontal endless tube 3 is the flat endless tubes of the mutually close level of forward and backward side pipe, its front tube is connected suspending rod 2 rear sides of fixed mount 1 below, upward centre portion is provided with pagoda layer pipe 31 (being three layers of pipe among Fig. 2,3) between the forward and backward side pipe of horizontal endless tube 3, and its both sides is respectively equipped with stacked tube 32 (being three layers of pipe among Fig. 2,3).

Horizontal endless tube 4 is the flat endless tubes of the mutually close level of forward and backward side pipe down, its front tube is connected suspending rod 2 rear sides of horizontal endless tube 3 belows, can partly be provided with pagoda layer pipe 41 (three layers of short pipe of the long rear side in front side among Fig. 2) between the forward and backward side pipe of the same horizontal endless tube 4 of this time, and its position, both sides is respectively equipped with stacked tube 42 (being three layers of identical pipe of length among Fig. 2).

Outer tube 5 is channel pipe structures, as shown in Figure 1, be connected simultaneously the rear tube of upper and lower horizontal endless tube 3,4 outer and bottom (flute profile base pipe) be lower than time horizontal endless tube 4, as shown in Figure 1, 2, the road surface runs into obstacle (as: stone is arranged, when the road surface difference of height is big) and can make outer tube 5 lower ends swing backward and lift when truck travels, as shown in Figure 2, therefore, this upper and lower horizontal endless tube 3,4 and outer tube 5 can not hinder vehicle '.

The present embodiment principle of work is as follows:

Bumper impact power (knocking into the back) when car, make the front tube of outer tube 5, rear tube, pagoda layer pipe 31,41, stacked

tube

32,42, upper and lower horizontal endless tube 3,4 through upper and lower horizontal endless tube 3,4, so multiple valve one-level level is hit the flat impulsive force that absorbs, and car decreases ring and can alleviate greatly; If impulsive force is also big, can make suspending rod 2 flexural deformation forward, even fixed mount 1 is destroyed, absorb impulsive force and stop that car can not creep into the truck bottom.

Claims

1, the anti-safe hanger that knocks into the back of a kind of truck, it is characterized in that: it mainly is by two fixed mounts, two suspending rod, on, a horizontal endless tube and an outer tube constitute down, wherein the back vertical plane upper end of two fixed mounts articulates corresponding two suspending rod upper end respectively, on, on down horizontal endless tube is, the following parallel flat endless tube of level, and all be connected the two suspending rod lower ends that are lower than fixed mount with its front tube, and on, the rear tube of horizontal endless tube connects an outer tube simultaneously down, last, before the following horizontal endless tube, centre portion between rear tube is connected pagoda layer pipe and stacked tube all respectively with the both sides part.

2, by the anti-safe hanger that knocks into the back of the described truck of claim 1, it is characterized in that: above-mentioned outer tube is the channel pipe structure.
