Problems solved by technology

[0005] In addition, in the case of using a hollow bellows-shaped impact absorber with exhaust pinholes, and absorbing impact energy by air compression resistance while allowing air to escape from the exhaust pinholes, it is also necessary to be certain in the direction in which the impact is applied. The height dimension cannot be applied to narrow parts or parts that cannot produce a certain height dimension
[0006] In addition, in a shock absorbing device that absorbs impact energy by buckling or cracking the resin ribs, the buckling state can be stably generated by appropriately setting the shape and material of the resin ribs, but due to differences in materials and molding conditions, etc. making the occurrence of cracks unstable
Therefore, it is necessary to change the shape of the resin rib each time due to the change of the material, etc., and there is a problem that the mold production cost and man-hours increase.

Embodiment 1

[0089] figure 1 The impact absorbing device of this embodiment is shown. This shock absorbing device 1 is composed of the following parts: the facing plate part 10; The space formed between the facing plate portion 10 and the pressure receiving plate portion 11 is divided into a plurality of small chambers. The cells formed by the facing plate portion 10 , the pressure receiving plate portion 11 , and the grid-like ribs 12 are each formed in a regular hexagonal cross-section, and are formed in a honeycomb shape as a whole.

[0090] Sections of multiple compartments such as figure 2 As shown, it is composed of a filled cell 13 filled with the enclosure 2 and an empty cell 14 filled with nothing but air. Around the filled cell 13, the positions corresponding to the sides of the cross-sectional hexagon are respectively connected to the empty cells. The chambers 14 are adjacent. In addition, on the 3 ribs 12 that are separated from each other by one rib among the 6 ribs 12 th...

Embodiment 2

[0098] However, in the shock absorbing device 1 of Example 1, it may be difficult for the enclosure 2 that has flowed into the empty cell 14 from the broken thin portion 15 to flow out of the enclosure 2 . For example figure 2 The illustrated empty cell 14a allows the inflow of the enclosure 2 from the adjacent filled cell 13, but cannot flow out to the other adjacent empty cell 14b or the like. Therefore, when the colliding object M penetrates further and comes into contact with the enclosure 2 in the filled cell 13 and the empty cell 14 that are communicated with each other through the broken thin-walled portion 15, the enclosure 2 is compressed and may rebound. .

[0099] Therefore, the shock absorbing device of the present embodiment is as Figure 7 As shown, the second thin-walled portion 16 is formed on the rib portion 12 that divides the adjacent empty cells 14 . With the configuration as described above, the enclosed body 2 is dispersed into the plurality of empty ...

Embodiment 3

[0101] The impact absorbing device of the present embodiment is formed on the portion opposite to the empty cell 14 of the opposing plate portion 10 . Figure 9 Except for the second thin portion 16 shown, it has the same structure as that of the first embodiment.

[0102] According to the shock-absorbing device of this embodiment, when the thin-walled part 15 breaks and the empty cell 14 is filled with the enclosure 2 and then compressed, the second thin-walled part 16 breaks, and the enclosure 2 is moved from the breakage to the shock-absorbing device. External discharge. Therefore, the bottoming phenomenon caused by the enclosure 2 can be eliminated.

Abstract

Disclosed is a collapsible device comprising charged cells (13) charged with a filling medium (2) composed mainly of a liquid, and vacant cells (14) charged with atmospheric air. At least one vacant cell (14) is adjacent to the charged cell (13), and at least one of ribs (12) defining the charged cells (13) and the adjacent vacant cells (14) has a fragile portion (15) formed therein. After the fragile portion (15) is broken, more impact energy can be absorbed by the flow resistance of the filling medium (2) which flows from the charged cells (13) to the vacant cells (14).

Description

technical field [0001] The present invention relates to an impact absorbing device arranged inside a door trim, a front pillar, a bumper, etc. to absorb impact energy at the time of a collision or the like. The shock absorbing device of the present invention can be used not only in automobiles but in various fields. Background technique [0002] As conventional shock absorbing devices, there are known hydraulic shock absorbers that absorb shock by compressing liquid with a piston, and devices that absorb shock energy by utilizing air compression resistance while allowing air to escape from an air pin hole. Wait. [0003] In addition, in recent years, a shock absorber in which a large number of resin ribs are arranged in a door trim and absorbs impact energy due to buckling or cracking of the resin ribs has been frequently used. The resin ribs are generally composed of a bottomed cylindrical outer wall and lattice-shaped ribs that divide the internal space formed in the out...
