Abstract
The invention discloses a buffering truck rear bumper device, composed of at least two supporting rocker arms, a corresponding number of fixed seats and combined annular frame, where the combined annular frame is connected of upper and lower annular pipes, plural erect pipes and plural groups of superposed pipes, the combined annular frame is connected with the lower segments of the supporting rocker arms through connection plate, the upper segments of the supporting rocker arms is hinged with the fixed seats through pin shaft, and elastic locking devices are arranged between the rocker arms and fixed seats; the combined annular frame is provided with steel plate identification tablet and the supporting rocker arms are provided with reflectors. The combined annular frame can absorb a part of impact energy as the impact happens, reducing the impact damage to the vehicle and the invention can make the truck lifted and freely drop and reset as the truck meets with obstruction in the running course.
Description
Technical field
The present invention relates to a kind of safety device that protects automobile rear, especially lorry rear bumper device.
Background technology
At present, highway in China still exists traffic to disclose crowded phenomenon, automobile situation following closely often appears, be easy to cause the traffic accident at lorry rear portion because of knocking into the back, many lorries at rear portion direct mount one channel-section steel as rear bumper, but because the flexural strength of channel-section steel is too high, the out of reach buffer action tends to make the vehicle that knocks into the back to cause very big damage.
Summary of the invention
The purpose of this invention is to provide a kind of lorry rear bumper device with buffer action, thereby the distortion that utilizes bumper system self alleviates the damage of the vehicle that knocks into the back, when lorry runs into obstacle under steam, can lift automatically, also have the anti-alarm function that knocks into the back simultaneously.
For this reason, technical scheme of the present invention is: lorry rear bumper device, by at least two support swing arms, with the permanent seat that supports the corresponding quantity of swing arm, combined annular frame composition; Wherein the combined annular frame is formed by connecting by many standpipes, the folded pipe of many groups by two ring pipes up and down, the combined annular frame is connected with support swing arm hypomere by the connecting panel on it, it is hinged by bearing pin and permanent seat to support the swing arm epimere, support between swing arm and the permanent seat and be provided with elastic locking device, it is characterized in that: the combined annular frame is provided with the steel plate Sign Board, supports swing arm and is provided with light deflector.
As a further improvement on the present invention, be in the support swing arm, to be provided with a plurality of pin shaft holes.
As a further improvement on the present invention, be that described ring pipe is formed by connecting by two straight tubes, joint for plastic tubes.
Beneficial effect: can pass through light deflector night prompting, steel plate Sign Board and remind automobile anti-rear end collision, when taking place to collide, absorb a part of crash energy by the combined annular frame, when alleviating automobile and colliding to the damage of vehicle; When meeting obstacle under steam, lorry can lift bumper system and free fall resets.Vertically be provided with a plurality of pin shaft holes on the permanent seat, can carry out up-down adjustment according to the height of car chassis the support swing arm is installed.Described ring pipe is formed by connecting by two straight tubes, joint for plastic tubes, can further improve the flexibility of ring pipe, improves buffer action.

The specific embodiment
Lorry rear bumper device shown in Fig. 1,2,3,4, by three support swing arms 6, with the permanent seat 2 that supports the corresponding quantity of swing arm, combined annular frame composition; Wherein the combined annular frame is formed by connecting by many standpipes 8, the folded pipe 10 of many groups by two ring pipes 1 up and down, the combined annular frame is connected with support swing arm 6 hypomeres by the connecting panel 7 on it, it is hinged by bearing pin 5 and permanent seat 2 to support swing arm 6 epimeres, supports between swing arm 6 and the permanent seat 2 and is provided with elastic locking device 13.The combined annular frame is provided with steel plate Sign Board 9, supports swing arm and is provided with light deflector 4.Permanent seat 2 is directly captiveed joint with cross member of frame 3, and normally permanent seat 2 is welded on the cross member of frame 3.
As shown in Figure 4, in support swing arm 6, be provided with a plurality of pin shaft holes 12, can install according to the height up-down adjustment of car chassis like this and support swing arm 6, to improve the commonality of bumper system.
As shown in Figure 2, ring pipe 1 is formed by connecting by two straight tubes, joint for plastic tube 11.When ring pipe 1 adopts two straight tubes to connect by joint for plastic tube 11, can further absorb a part of crash energy, the buffering impulsive contact force.Certainly, ring pipe 1 also can be to form with a straight tube bending.
The quantity of above-mentioned support swing arm 6 is not limited to three, can be two or more.
When at styling design different series product, it can be one at the pin shaft hole 12 that supports in the swing arm 6.
As shown in Figure 5, when lorry rear bumper device is met obstacle, support in the swing arm 6 and lift around bearing pin 5.
Claims (3)
