The specific embodiment
Following examples are used to illustrate the utility model, but are not used for limiting protection domain of the present utility model.
Fig. 1 is the structural representation sketch of emergency glass crushing device described in the utility model.As shown in Figure 1, the emergency glass crushing device of present embodiment has housing 1, is provided with firing unit 2, firing unit seat 4 and firing pin 3 in the housing 1.
Firing unit 2 places in the firing unit seat 4 and towards the direction of firing pin 3.The firing unit that can adopt similar safe automobile air bag to adopt.Be specifically as follows: firing unit 2 one ends have two core electrodes 9 that are used to connect direct supply, and the other end has a coyote hole that the medicament that detonates is housed, and when core electrode 9 continue to be surpassed the DC current institute conducting of 3ms by 1.5A, the medicament that detonates will ignite.
Firing pin 3 is located on the inwall of housing 1 other end, and is interference fit between the housing 1, and housing 1 other end is the opening shape, in be provided with and be used to the spacing preiection 11 that prevents that firing pin 3 from deviating from, firing pin can integral body not flown out in shattered glass.
Firing pin 3 is a column, one end has the firing pin lug 10 that matches with spacing preiection 11, the other end is pointed, and be that preceding sharp back is blunt, fwd tapered point razor-edge profit, be beneficial to firing pin and thrust glass, the opening moment change that the obtuse angle of back can make glass cause because of firing pin front acute angle thrusts is big, thereby makes the easier fragmentation of glass.Firing pin 3 can be along housing 1 inwall towards treating that cullet slide under the high pressure gas of firing unit 2 and medicament 5 generations promote.
The effective length of firing pin 3 (rushing in the degree of depth of glass) can be adjusted when design according to the thickness of glass, to guarantee breaker described in the utility model except shattered glass, does not have any fragmentation and flies out with hard thing.
Firing pin 3 under normal circumstances can not move in housing, and firing pin 3 external diameters and housing 1 internal diameter have a small amount of interference, reaches firing pin 3 in housing 1 internal fixation and leak free purpose, can be by realizing at firing pin 3 cylindricals assembling O RunddichtringO yet.
On firing unit seat 4, also be provided with short-circuited conducting sleeve 6, be located on the firing unit seat 4, link to each other with firing unit 2.
Short-circuited conducting sleeve 6 has two elastic sheet metals 8, and it is used for cut-in point firearm two core electrodes 9 makes its short circuit.Like this, when breaker described in the utility model did not use, holding point firearm two core electrodes were in short-circuit condition, can not be ignited by any power source, to guarantee its safety.During use, when the utility model breaker was connected with external circuit, short-circuited conducting sleeve can be removed short circuit and be in open-circuit condition, can be ignited by ignition signal at any time.
If the utility model breaker is installed on the vehicle such as automobile, also can set the logical test circuit of simple weak point at the instrument carrier panel place, be used to judge the coupled condition of this device and whole circuit.Thereby guarantee that this device can intelligent self check, Failure Alarm.Conscientiously guarantee passenger safety crucial moment.
Be example on the vehicle such as automobile, train, subway, steamer, to use, emergency glass crushing device of the present utility model can link to each other by lead the core electrode 9 of firing unit 2 with external source, as be provided with short-circuited conducting sleeve 6, can be by the plug special of the butt joint that matches with it.After plug inserted, short-circuited conducting sleeve was used for short circuited elastic metallic sector-meeting by the plug positive opening, removed short circuit.Short-circuited conducting sleeve and banjo are the standard connector.External source can be an automotive battery, also can the special DC power supply.
Firing pin 3 exit end of emergency glass crushing device of the present utility model can adjacently be treated cullet, and are fixed in window edge with a holding device, have connection lead to link to each other with the starter gear on driver next door.Treat to be in an emergency in the car need be with glass crushing the time, chaufeur can start by starter gear rapidly, thereby all fixing glass on the whole car were all smashed in moment, for the passenger wins the time of fleeing from.
Starter gear can be a danger button, also can use car and start key, and all can be used for electric current and sends and can guarantee that when not using safe switch shape puts.
When only using firing unit 2 to smash thin case hardened glass, the mechanism of the utility model breaker is as follows: after breaker is received firing command, firing unit 2 can produce a large amount of gases rapidly about 2ms, it is approaching with glass crushing to glass rapidly that gas will drive firing pin 3, perhaps glass is hit into penetrating crack, only need the passenger to promote gently, bulk glass is toppled outside car, thereby hew out tunnel escape.
When needing the thicker or hardness of broken case hardened glass hard, device can assemble an amount of medicament 5 except that firing unit, between firing unit 2 and firing pin 3.The assembling quantity of medicament is obtained by calculating or testing by strength of glass and thickness.After the utility model breaker receives firing command, firing unit 2 medicament 5 that can start rapidly and ignite, a large amount of gases that firing unit 2 and medicament 5 produce are pushed firing pin 3 to glass at faster speed, thereby with viteous fracture, reach the effect of opening up tunnel escape.
Emergency glass crushing device of the present utility model is safe and reliable, can not misquote because of quilts such as automobile bumpiness, vibrations, bump, stray current, electromagnetic interference and send out.Its used firing unit and medicament all select to satisfy the product of GB/T 19949 and standard codes such as " USCAR INFLATOR TECHNICALREQUIREMENTS and VALIDATION ".
Though, above with a general description of the specific embodiments the utility model having been done detailed description, on the utility model basis, can make some modifications or improvements it, this will be apparent to those skilled in the art.Therefore, these modifications or improvements on the basis of not departing from the utility model spirit all belong to the claimed scope of the utility model.
