Description

Technical Field

[0001] The invention relates to the technical field of automobile accessories, and in particular to a fuel tank side energy absorption and anti-collision device. Background Art

[0002] With the rapid development of my country's economy, transportation plays a very important role. Among them, convenient and efficient transportation and travel modes such as rail transportation and road transportation have become an indispensable part of people's lives, so safety protection issues have become indispensable. Without safety protection, once an accident occurs, when a moving vehicle collides, the huge kinetic energy carried by the high-speed mass body will be dissipated in various forms of energy in an instant, causing huge property losses and casualties. The fuel tank contains flammable and explosive gasoline, which is easy to explode and catch fire when it collides. Therefore, how to prolong the energy dissipation time, absorb a large amount of kinetic energy in a short time, and protect the safety of the fuel tank has become a difficult problem that the anti-collision energy absorption device installed on the vehicle must overcome.

[0003] The existing technology only increases the thickness of the outer wall of the fuel tank to increase the structural stability of the fuel tank. However, when the fuel tank is hit, it will still be subjected to a large impact force, and the impact force acts directly on the fuel tank. The fuel tank is easily subjected to the impact force and explodes, and the safety of the fuel tank cannot be protected. Summary of the invention

[0004] Based on the technical problem that a fuel tank is easily deformed and exploded when hit, the present invention proposes a fuel tank side energy absorption and anti-collision device.

[0005] A fuel tank side energy absorption and anti-collision device proposed in the present invention includes a fuel tank body and a protective layer, the fuel tank body is arranged inside the protective layer, the bottom outer wall of the protective layer is fixed with a fixed vertical plate, and the top outer wall of the fixed vertical plate is fixed with a support plate, the top of the support plate is fixed with a first mounting plate, and the bottom outer wall of the first mounting plate is fixed with two symmetrically distributed first fixed plates, the bottom outer wall of the protective layer is located between the fixed vertical plates and fixed with a fixed horizontal plate, and the inner walls on the opposite sides of the fixed horizontal plate are fixed with two symmetrically distributed second fixed plates, the top outer wall of the second fixed plate is fixed with equidistantly distributed first springs, and the top of the first spring is fixedly connected to the bottom outer wall of the first fixed plate.

[0006] Preferably, a first connecting rod and a second connecting rod are respectively fixed to the inner walls of the left and right opposite sides of the support plate, and the middle positions of the first connecting rod and the second connecting rod are fixedly connected by a connecting shaft.

[0007] Preferably, support rods distributed equidistantly are fixed to the inner walls on both sides of the support plate, and a reinforcement block is fixed between the outer wall on one side of the support plate and the top outer wall of the fixed vertical plate.

[0008] Preferably, the top outer wall of the first mounting plate is provided with evenly distributed buffer members, and the top ends of the buffer members are fixedly connected to the first bottom plate.

[0009] Preferably, an energy absorbing wall is fixed to the top outer wall of the first bottom plate, and an energy absorbing plate is provided on the top outer wall of the energy absorbing wall.

[0010] Preferably, the buffer comprises C-shaped steel, a second spring, a first inclined plate, a connecting plate, and a second inclined plate, and the first inclined plate and the second inclined plate are respectively fixed at the upper and lower ends of the connecting plate, and the other ends of the first inclined plate and the second inclined plate are fixedly connected to the arc-shaped inner wall of the C-shaped steel.

[0011] Preferably, one end of the second spring is fixed to a side of the connecting plate close to the arc-shaped inner wall of the C-shaped steel, and the other end of the second spring is fixedly connected to the middle position of the arc-shaped inner wall of the C-shaped steel.

[0012] Preferably, the front and rear outer walls of the protective layer are provided with first energy dissipation holes, and the left and right outer walls of the protective layer are provided with second energy dissipation holes.

[0013] Preferably, four symmetrically distributed rectangular holes are opened on the top outer wall of the protective layer, and a top plate is fixed to the bottom inner wall of the protective layer.

[0014] Preferably, second S-shaped elastic members distributed equidistantly are fixed to upper and lower inner walls of the first energy unloading hole, and first S-shaped elastic members distributed equidistantly are fixed to upper and lower inner walls of the second energy unloading hole.

[0015] The beneficial effects of the present invention are:

[0016] 1. Through the arrangement of the fixed vertical plate, the second fixed plate, the first spring and the protective layer, when a collision occurs, the protective layer collides with the outside world, absorbs the energy generated by the impact force, and deforms and contacts the internal buffer structure. The first mounting plate is forced to move downward, the support plate is forced to bend, and the first spring is shortened to absorb part of the energy generated by the collision and unload most of the internal force generated by the collision, thereby protecting the safety of the fuel tank and preventing the fuel tank from exploding due to a strong collision, causing heavy losses and casualties.

[0017] 2. By setting up the energy-absorbing plate and the second fixed plate, the wavy energy-absorbing plate increases the collision contact area and reduces the collision pressure. The wavy front of the energy-absorbing plate is easier to deform than the rectangular flat plate when a collision occurs, which can effectively reduce the initial peak stress during the collision. At the same time, the deformation of the energy-absorbing plate can absorb the energy generated by the collision, increase the energy absorption characteristics, and better protect the integrity of the fuel tank.

[0018] 3. Through the buffer component, when the first bottom plate and the first mounting plate are squeezed, the C-shaped steel is deformed, and the second spring is forced to extend outward, converting the internal energy generated by the impact into the elastic potential energy of the buffer component, thereby improving the energy absorption effect of the device, and the impact resistance is also increased, thereby better protecting the safety of the fuel tank.

[0019] 4. By setting the first S-shaped elastic member and the second S-shaped elastic member, the first S-shaped elastic member and the second S-shaped elastic member have deformation resistance and pressure resistance. When the first energy unloading hole and the second energy unloading hole are deformed by external force, the external force causes the first S-shaped elastic member and the second S-shaped elastic member to bend, and the first S-shaped elastic member and the second S-shaped elastic member absorb the collision energy, thereby enhancing the structural safety of the first energy unloading hole and the second energy unloading hole and protecting the fuel tank.

When an impact occurs, the protective layer 5 collides with the outside world and absorbs the energy generated by the impact force. The protective layer 5 is deformed, and the wavy energy-absorbing plate 26 increases the collision contact area and reduces the collision pressure. The wavy front of the energy-absorbing plate 26 can effectively reduce the initial peak stress during the collision when a collision occurs.
