Such as ambulances, fire-fighting vehicles, dangerous goods transportation vehicles, police vehicles, engineering dangerous vehicles, military supervision vehicles, etc.
In dangerous goods transport vehicles, an oil tank truck is one of common vehicles on roads, a large amount of fuel oil is loaded in the oil tank truck, and the danger of leakage or explosion exists when the oil tank truck encounters a collision or rear-end collision, so that how to avoid the rear-end vehicle from striking an oil tank is important when the oil tank truck encounters a rear-end collision.
Disclosure of Invention
The utility model provides a special vehicle anti-collision mechanism based on at least one of the technical problems.
A special vehicle anti-collision mechanism comprising: the rear anti-collision beam is fixedly arranged at the rear part of the vehicle body longitudinal beam, and an energy absorption buffer box is arranged between the rear anti-collision beam and the vehicle body longitudinal beam; the upper sides of two sides of the vehicle body longitudinal beam are provided with a front upright post and a rear upright post which are vertically arranged, the front upright post and the rear upright post are mutually fixed through a reinforcing rod, and the reinforcing rod is also arranged between the rear side of the front upright post and the vehicle body longitudinal beam; the rear column rear side is equipped with a plurality of horizontal poles, the outside of horizontal pole is equipped with the arc anticollision auxiliary girder that the array set up, the afterbody at the oil tank is wrapped up in to the anticollision auxiliary girder.
In one possible implementation manner, the rear side of the rear anti-collision beam is a triangular beam with a protruding middle, two side edges of the rear side of the rear anti-collision beam are provided with rotating wheels with uniform intervals, and the rotating wheels are installed on the side edges of the rear anti-collision beam through rotating shafts.
In one possible embodiment, a support bar is provided between the front side of the rear pillar and the body rail.
The beneficial effects are that: the special vehicle anti-collision mechanism adopts a special rear anti-collision beam, and when a small vehicle is in rear-end collision or a large vehicle is in rear-end collision, the rotating wheel on the rear anti-collision beam can deflect the collision, so that the impact on the vehicle body is reduced; when a rear-end collision of a large vehicle is encountered, the anti-collision auxiliary beams on the longitudinal beams of the vehicle body can well protect the tail of the oil tank, and when a collision with a larger speed is encountered, the anti-collision auxiliary beams distributed in an array can also reduce penetration of the protruding parts of the rear vehicle to the oil tank.
Drawings
FIG. 1 shows a schematic structural view of the present utility model;
fig. 2 shows a schematic structural view of the rear impact beam of the present utility model.
Detailed Description
In order that the above-recited objects, features and advantages of the present utility model will be more clearly understood, a more particular description of the utility model will be rendered by reference to the appended drawings and appended detailed description. It should be noted that, in the case of no conflict, the embodiments of the present application and the features in the embodiments may be combined with each other.
Example 1
The special vehicle anti-collision mechanism as shown in fig. 1-2 comprises: the rear anti-collision beam 1, the rear anti-collision beam 1 is fixedly arranged at the rear part of the car body longitudinal beam 2, an energy-absorbing buffer box 9 is further arranged between the rear anti-collision beam 1 and the car body longitudinal beam 2, and when a rear-end collision is encountered, the energy-absorbing buffer box 9 can reduce the impact on the car body during energy absorption and buffering.
The upper sides of two sides of the longitudinal beam 2 of the vehicle body are provided with a front upright post 4 and a rear upright post 3 which are vertically arranged, the front upright post 4 and the rear upright post 3 are mutually fixed through a reinforcing rod 5, and the reinforcing rod 5 is also arranged between the rear side of the front upright post 4 and the longitudinal beam 2 of the vehicle body; the rear side of the rear upright post 3 is provided with a plurality of cross bars 6, the outer side of the cross bars 6 is provided with an arc-shaped anti-collision auxiliary beam 7 arranged in an array, the anti-collision auxiliary beam 7 wraps the tail of the oil tank, and a supporting rod 8 is arranged between the front side of the rear upright post 3 and the longitudinal beam 2 of the vehicle body.
Specifically, when the collision with a larger speed is encountered, the anti-collision auxiliary beams 7 distributed in an array can also reduce penetration of the protruding part of the rear vehicle to the oil tank; the front pillars 4, rear pillars 3 and their support structures can provide sufficient strength support in the event of a collision at a low speed, avoiding collision of the rear vehicle to the tank.
Example two
As shown in fig. 2, the rear side of the rear anti-collision beam 1 is a triangular beam with a protruding middle part, the two sides of the rear side of the anti-collision beam are provided with rotating wheels 10 with uniform intervals, the rotating wheels 10 are arranged on the side of the rear anti-collision beam 1 through rotating shafts 11, and when encountering a rear collision, the impact force can be dispersed under the action of the rotating wheels 10.
