Detailed Description
The principles and features of the present invention are described below in conjunction with the following drawings, the illustrated embodiments are provided to explain the present invention and not to limit the scope of the invention.
As shown in fig. 1-4, embodiment 1 of the present invention provides an automobile anti-collision structure, which includes a frame 1 and an anti-collision fence 2, the frame 1 and the anti-collision fence 2 are fixedly connected by a first bolt 3 and a nut 4, a horizontal plate 7 is horizontally disposed on the opposite surface of the frame 1 and the anti-collision fence 2, an arc plate 6 is disposed on the horizontal plate 7, the arc plate 6 is in a semi-circular shape and has an opening facing the frame 1, a driving plate 5 abutting against the arc plate 6 is disposed on the opposite surface of the anti-collision fence 2 and the frame 1, an L-shaped rod 8 is further included, the vertical end of the L-shaped rod 8 is fixedly connected to the frame 1, the horizontal end of the L-shaped rod 8 and the outer wall of the arc plate 6 abutting against the arc plate 6 can be stacked together by three arc plates with decreasing radii, the radius is the smallest one close to the frame 1, when the arc plate 6 is extruded to be broken, the arc plate 6 firstly, through the sequential fracture of the three layers of arc-shaped plates 6, the impact force generated by collision of the frame 1 with an object due to inertia can be better relieved, the energy absorbed by the material with higher toughness is larger when the material is fractured, and the energy is absorbed in order to ensure that the arc-shaped plates 6 can be fractured normally, so that the base steel (5Cr4W3Mo2V) can be adopted and has better toughness.
When the collision-prevention fence 2 collides with an object, the collision-prevention fence 2 slows down the movement due to the fact that the collision-prevention fence 2 touches the object, the frame 1 moves forwards due to inertia, the collision-prevention fence 2 slows down the speed, the collision-prevention fence 2 and the frame 1 move relatively, the frame 1 and the collision-prevention fence 2 are in contact with the arc-shaped plate 6 through the transmission plate 5, the arc-shaped plate 6 is extruded to be broken and broken by impact force generated by collision of the collision-prevention fence 1 and the frame, energy is absorbed by the way that the arc-shaped plate 6 is broken, impact force generated by collision of the frame 1 and the object due to inertia is relieved, no resilience force exists after the arc-shaped plate 6 is broken, and secondary; in addition, since both sides of the arc plate 6 are fixed by the horizontal ends of the L-shaped bars 8, the arc plate 6 can be normally extended toward the inside of the L-shaped bars 8 when the arc plate 6 is pressed.
The embodiment 2 provides an automobile anti-collision structure, on the basis of embodiment 1, be equipped with circular cone piece 9 on the first bolt 3, be equipped with the cover on frame 1 and establish drum 10 on circular cone piece 9, seted up opening 11 on drum 10, when anticollision fence 2 and frame 1 relative motion, circular cone piece 9 also removes towards drum 10's inside, because there is opening 11 on drum 10 for drum 10 is strutted by circular cone piece 9 gradually, through the mode of drum 10 deformation, impact force when slowing down both collisions.
The embodiment 3 of the utility model provides a car anticollision structure, on the basis of embodiment 2, the outer wall contact of rubber block 12 and arc 6 is passed through to the horizontal end of L type pole 8, and frictional force when increase and arc 6 contact improves the stability of arc 6.
The embodiment 4 of the utility model provides a car anticollision structure, on the basis of embodiment 3, L type pole 8 is connected with frame 1 through second bolt 13, and when second bolt 13 passed through screw-thread fit screw in frame 1 on, the horizontal end of L type pole 8 contacted with the outer wall of arc 6 gradually to compress tightly the outer wall of arc 6 gradually, improve the stability of arc 6.
The embodiment 5 of the utility model provides an automobile anti-collision structure, on the basis of embodiment 4, driving plate 5 contacts with arc 6 through convex block 14, because convex block 14 is protruding form, when convex block 14 and arc 6 contact, driving plate 5 can not contact with L type pole 8, guarantees that driving plate 5 can continuously carry out the contact extrusion to arc 6.
