Description
Technical field
The utility model relates to a kind of gas generator, specifically, is a kind of for the air bag gas generating mechanism in electronic product protecting shell.
Background technology
Current various electronic equipment protection shells on the market adopt plastics, silicon rubber and metal material to form mostly.Along with the size of electronic product is increasing; its weight also increases accordingly; the containment vessel of existing this version and material; when when being subject to external impacts; most impulsive force still can act directly on electronic product through containment vessel, if external force is comparatively large, the impulsive force of generation can be larger; the impulsive force be like this subject to for product can produce destruction to it, even internal injury.Through experimental verification, existing market product is almost difficult to meet for the protection of maximum conditions (more than 1.5 meters freely falling bodies and product corner or front first contact with ground).
Existing patent, the one mentioned in Authorization Notice No. (CN 203311316U) protection leather sheath.This leather sheath increases an air cushion at 8 angles place, and also there is over cap in front.Although the protective capability to electronic equipment can be improved; but this kind of scheme owing to adding larger air cushion on 8 angles; very large on product appearance impact; and this kind of scheme has 4 air cushions to be arranged on front protecting to cover, user in use time, be certain to open over cap; if during this time product drops; then front is in that a kind of product is easy to be destroyed without any under the state of safeguard measure, so the protection of this kind of scheme has certain limitation completely.
Utility model content
For the deficiencies in the prior art; the utility model provides a kind of gas generator; be mainly used in the air feed demand of air bag in electronic product protecting shell; adopt this gas generator, the air bag in Electronic Protection shell can be made usually to be in contraction state, can not product appearance be affected; once detect that product drops; this gas generator can be triggered and produce enough gas, air bag is expanded, thus prevent collision.
For achieving the above object, the concrete technical scheme that the utility model adopts is as follows:
A kind of gas generator, its key is: be provided with the first container cavity and the second container cavity, wherein the first container cavity is for filling NaN
3, the second container cavity is for loading NH
4nO
3isolated by barrier film between described first container cavity and the second container cavity, and the chamber pressure of the first container cavity is greater than the chamber pressure of the second container cavity, the sidewall of described first container cavity is provided with electrode interface, this electrode interface is connected with an electric arc, described electric arc stretches in the chamber of described first container cavity, and the end of this electric arc is just to described barrier film, and the sidewall of described second container cavity is also provided with puff prot.
Adopt this gas generator, normal condition, the NaN in the first container cavity
3with the NH in the second container cavity
4nO
3isolated by barrier film, in a safe condition, when needs produce gas, trigger membrane ruptures by electric arc, the chamber pressure due to the first container cavity is greater than the chamber pressure of the second container cavity, and in the moment of membrane ruptures, the gas shock between chamber can cause NaN
3with NH
4nO
3react, thus produce enough gas, this mechanism is connected with the air bag on containment vessel, thus plays a protective role.
As further describing, described barrier film is can by the plastic film of arc through.
For the ease of modularized design, at described puff prot, the conduit for connecting air bag being installed, facilitating the replacement of whole module.
As preferably, in described first container cavity, be preinstalled with NaN
3, in described second container cavity, be preinstalled with NH
4nO
3, this mechanism can carry out processing and producing as independent module, uses convenient.
Remarkable result of the present utility model is:
NaN is loaded by arranging separate chamber
3and NH
4nO
3middle barrier film is punctured by controlling electric arc; the two is made to issue biochemical reaction in the triggering of outside energy; the a large amount of gases utilizing chemical reaction to produce are to meet the air feed demand of air bag; structure is simple, easy for installation, can realize miniaturization, modularized production; be applied in the electronic product protecting shell with air bag, because collide the damage caused when can effectively prevent electronic product from falling.
Accompanying drawing explanation
Fig. 1 is the utility model forward structure schematic diagram;
Fig. 2 is the utility model side direction structural representation.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model and operation principle are described in further detail.
As Figure 1-Figure 2, a kind of gas generator, be provided with the first container cavity 1 and the second container cavity 2, wherein the first container cavity 1 is for filling NaN
3, the second container cavity 2 is for loading NH
4nO
3isolated by barrier film 3 between described first container cavity 1 and the second container cavity 2, and the chamber pressure of the first container cavity 1 is greater than the chamber pressure of the second container cavity 2, the sidewall of described first container cavity 1 is provided with electrode interface 4, this electrode interface 4 is connected with an electric arc 5, described electric arc 5 stretches in the chamber of described first container cavity 1, and the end of this electric arc 5 is just also provided with puff prot 6 to described barrier film 3 on the sidewall of described second container cavity 2.
In specific implementation process, described barrier film 3 is can by the plastic film of arc through.
In order to satisfied miniaturization, modularized production, at described puff prot 6, the conduit for connecting air bag is installed, and is preinstalled with NaN in described first container cavity 1
