Abstract

The invention discloses a car body collision buffer device, comprising at least one buffering body, at least one base, at least one connecting rod group and at least one ratchet structure. The connecting rod group comprises a plurality of connecting rods, at least one upper slide block and at least one lower slide block, wherein the upper slide block is connected to the buffering body; the lower slide block is connected to the base; the upper slide block is driven by the plurality of connecting rods and can slide between a first position and a second position in a reciprocating manner; the lower slide block is driven by the plurality of connecting rods and can move from a third position to a fourth position; and the lower slide block is located at the third position by the ratchet structure. When the ratchet structure releases the lower slide block, the lower slide block can slide to the fourth position from the third position and can drive the plurality of connecting rods to drive the upper slide block to move to the second position from the first position, and the buffering body is pushed by the upper slide block to move to an unfolding position from a folding position.

Description

technical field

[0001] The invention relates to a vehicle body collision buffer device, in particular to a buffer device combined with an extension mechanism and a rod structure. Then stretch out to become an effective collision buffer device, so that the vehicle can take into account the lightweight and anti-collision ability of the vehicle body, and is easy to recycle and even reuse. Background technique

[0002] Compact and light-duty vehicles have the advantages of energy saving, small parking space, flexible mobility, and high occupancy rate, which is one of the trends in future vehicle evolution. However, the compact body has almost no additional buffer space to absorb the impact and energy of the accidental collision of the vehicle, which leads to problems in the collision safety of the vehicle body.

[0003] Generally, when a car is hit, it usually uses the deformation of the car body itself (steel plate, bumper, chassis main beam) to absorb the impact energy. Its s...

Embodiment Construction

[0047] The technical means and effects used by the present invention to achieve the purpose will be described below with reference to the accompanying drawings, and the embodiments listed in the following drawings are only for auxiliary illustration, but the technical means of this case are not limited to the listed drawings.

[0048] see Figure 1 to Figure 4 The embodiment structure of the vehicle body collision buffer device provided by the present invention is shown. The buffer device 10 includes a buffer body 11 and a base 12. The buffer body 11 includes a rigid body 111 and a soft body 112. The rigid body 111 is made of steel, iron and other metal materials. The flexible body 112 is made of elastic and shock-absorbing materials, such as foam and sponge. The flexible body 112 is arranged on one side of the rigid body 111 . The base 12 is fixedly arranged at any desired position in the vehicle body, and the base 12 is made of metal materials such as steel and iron.
