Specifically, the weakened area position of pressurize gasbag corresponds with 8 bar shape disappointing hole 24 positions on the outer lane 22 of seal support body 2 for the pressurize gasbag is after the weakened area takes place to break, and the release from disappointing hole 24 that can be quick effectively reduces pedestrian's head injury.
In some other embodiments, the sealing support body 2 is provided with a gas release hole 24, the gas release hole 24 is configured to be in a closed state in an inflated state and in a ventilation state in the gas release state, so that when the sealing support body 2 is impacted, the sealing support body 2 changes from the inflated state to the gas release state, and the gas in the inner cavity of the support body can be released by changing the gas release hole 24 from the closed state to the ventilation state, so that the inner cavity of the support body can be folded quickly, and the injury degree of the head of the pedestrian is reduced.
Preferably, the soundproof cotton body 1 and the sealing support body 2 are of an integrally molded structure. The seal support body 2 is constructed by increasing the mode of the protruding structure on the soundproof cotton body 1 of the automobile cover, so that the integration level is higher, the integral structure formed by the soundproof cotton body 1 and the seal support body 2 is convenient to detach and replace directly from the automobile cover, and the production cost is reduced.
Preferably, the acoustic cotton body 1 and the sealing support 2 are made of an elastic material. The elastic material may be rubber or PVC or silicone rubber or the like.
Fig. 2 is a schematic structural diagram of the sealing support body 2 in an inflated state, fig. 3 is a schematic structural diagram of the sealing support body 2 in a deflated state, and referring to fig. 2 and 3, the collapsing deformation process of the sealing support body 2 is as follows:
1) the automobile cover is covered on the automobile front cabin, and the sealing support body 2 is extruded on a sealing strip of the storage box of the automobile front cabin in an inflated state;
2) when the automobile cover is impacted by the head of a pedestrian, the pressure maintaining air bag is broken in the weakening area;
3) the gas in the pressure maintaining air bag is released from the air release hole 24;
4) the inner and outer rings 21 and 22 are folded at the folded portion 23, so that the seal support body 2 is deformed by collapsing;
5) the sealing support body 2 is completely transformed into the air leakage state from the inflation state, and the sealing support body 2 in the air leakage state is attached to the soundproof cotton body 1 to absorb energy and release enough space for the head of a pedestrian.
Example 2:
the embodiment of the specification provides an automobile cover assembly, which comprises an automobile cover and a cover soundproof cotton device which can be deformed in a collapsible manner in the embodiment 1, wherein the cover soundproof cotton device is fixedly arranged on the inner side of the automobile cover. Use collapsible deformation's seal support body 2 to have replaced b structure (rigid plastic) among the prior art among the car cover assembly for pedestrian's head energy-absorbing buffer space an + c becomes a + b + c again, has effectively solved between cover and the storing box good sealed state and can have been presented when the cover receives suddenly stronger impact again and contract deformation and come for pedestrian's head quick release energy-absorbing space, reduces the injured degree of head.
