In second embodiment of emergency oxygen equipment 101 shown in Figure 2, energy storage device 109 is coupled in transmitter 103 through cable 114.Further, in this embodiment, controller 105 is coupled in transmitter 103 and activated equipment 111 is coupled in controller.Through energy storage device 109 is connected with transmitter 103, energy storage device 109 receives electric energy to be stored from transmitter 103.Transmitter 103 is applicable to voltage that the cardinal principle of first energy level is constant and low current amplitude transmission.Energy storage device 109 these electric energy of storage are until the energy of having stored specified quantitative.Use the keep voltage of constant energy transmission then as energy storage device 109.In case of emergency, transmitter 103 will send short peak voltage signal.Controller 105 these differential voltage of identification and result make energy storage device 109 and activated equipment 111 telecommunications.
In Fig. 2, the shell of emergency oxygen equipment 101 is not shown.Yet preferably, this emergency oxygen equipment 101 or its at least a portion wrap in the shell.In alternate embodiments, activated equipment 111 also can be arranged in housing exterior and be coupled in lock bolt, activates emergency oxygen equipment with the bottom through the shell shown in the release graphics 1.
Comprise wireless receiver 203, first energy storage device 209 and second energy storage device 225 with reference to figure 3, the three embodiments.This first energy storage device 209 is coupled in controller 205 through cable 217.Second energy storage device 225 is coupled in wireless receiver 203 through cable 227.In alternate embodiments, second energy storage device 225 also can integrate with wireless receiver 203.Energy storage device 229,225 all is coupled in energy source 207.This energy source 207 can be aircraft energy system or any other energy source.Preferably, energy source 207 is collection of energy elements.This collection of energy element 207 can be attached to the shell of emergency oxygen equipment 211 and be suitable for converting the mechanical energy of coming self-excited oscillation, acceleration etc. that acts on this shell to electric energy.This collection of energy element 207 can comprise the induction coil with removable magnetic core; This magnetic core is arranged in the coil; Thereby and produce bias voltage through mechanical spring and be exposed under the situation that magnetic core moves with respect to the vibratory movement effect of coil at shell and collection of energy element 207, allow the interior induction electric energy of coil.
The electric energy that produces in the collection of energy element 207 is supplied to first and second energy storage devices 209,255 through cable 215.Therefore, in case of emergency, will offer wireless receiver from the energy of second energy storage device 227 and will offer activated equipment from the energy of first energy storage device 209.
Because in case of emergency, the energy that is enough to activated equipment 211 is activated in first energy storage device, 209 storage inside is crucial, two independent energy storage devices 209,225 of therefore preferred enforcement.Yet in alternate embodiments, wireless receiver 203 is coupled in identical energy storage device with controller 205.In this embodiment, be necessary to ensure that at any time the amount of the energy of being stored all is enough to move activated equipment 211.
Emergency oxygen equipment 301 with reference to figure 4, the four embodiments comprises the controller 305 with integrated sensor.In this embodiment, energy storage device 309 through cable 317 and controller 305 couplings and with energy source 307 couplings, energy source 307 can be the aircraft energy system or as before described gathering element.If integrated sensor records low cabin height above sea level air pressure in the controller 305, this makes and is necessary for passenger's supply oxygen that controller 305 makes energy storage device 309 for to be electrically connected with activated equipment 311, to activate emergency oxygen equipment 301.Preferably, all these elements can be contained in the shell.This causes productive costs to reduce, because reduced the complexity that emergency oxygen equipment 1,101,201,301 is assembled in the aircraft.
Under the situation that the aircraft cabin internal gas pressure descends suddenly, emergency oxygen equipment 1,101,201,301 according to the present invention will be worked as follows.Through signal cable 13,113, wireless signal path 223 or through being integrated in after sensor in the controller 305 receives emergency signal, controller 5,105,205,305 makes energy storage device 9,109,209,309 for to electrically contact with activated equipment 11,111,211,311.Therefore, electric energy flows to activated equipment through cable 17,19,117,119,217,219,317,319 from energy storage device.Parallel therewith, controller sends a signal to activated equipment, to activate emergency oxygen equipment 1,101,201,301 fully.Activation during activating the bottom 4 refer to shell 2 fully and open here so that oxygen mask is offered the passenger, and makes Oxygen Flow to face shield.Therefore not exclusively activating to refer to makes this bottom 4 remain on the activation of constrained position.
If should test to emergency oxygen equipment 1,101,201,301; Workflow is followed the identical step of explaining as preceding; But have following difference, that is, and transmitter 3,103 send test massage controller 5,105,205,305 or wireless receiver 203.Controller 5,105,205,305 electrically contacts energy storage device 9,109,209,309 and activated equipment 11,111,211,311 then, and also sends signal so that not exclusively activate emergency oxygen equipment 1,101,201,301.Therefore, emergency oxygen equipment 1,101,201,301 equipment 11,111,211,311 that is activated not exclusively activates.The incomplete activation here refers to and makes bottom 4 remain on the activation of constrained position, so that oxygen mask remains on device interior and do not provide to the passenger.Under this test case, there is not oxygen to flow to face shield.In alternate embodiments, emergency oxygen equipment 1,101,201,301 comprises lamp or other signal generation apparatus, and this signal generation apparatus is activated to send emergency oxygen equipment 1,101,201,301 signal of correct work.
With reference to figure 5 to 10, it at length shows and is used for framework 400 emergency oxygen equipment 1,101,201,301, that can be used as an emergency oxygen equipment part.Framework 400 comprises the base plate 404 with opening 402, and this opening 402 is centered on by edge 406.Side at base plate 404 is equipped with bearing set 408.At opposite side, bottom 4 by 21 pivots of hinge be fixed on an end of base plate.At off position (Fig. 5,8), bottom covers opening 402.The oxygen mask (not shown) can be stored in bottom top, in case discharge bottom 4, oxygen mask just can pass opening 402 drop (Fig. 7,10).
Further, framework 400 comprises lock bolt 12.Lock bolt 12 in this embodiment comprises first uncinus 418 and second uncinus 422.First uncinus 418 is with hole 420 runnings.The two all is roughly the direction perpendicular to base plate 404.Bottom 4 is fixed in and the opening on the extend through base plate 404 414 when bottom 4 is positioned at off position in hole 420.First uncinus 418 is connected in bar 426, and wherein the two all passes through rod 410 with respect to 408 pivot ground installations of bearing set (holding means).Be installed to activated equipment 411, in this embodiment, this activated equipment 411 is embodied as electromagnetic component 426 pivots of bar.Activated equipment 411 is fixed in bearing set 408 and is connected in energy source or controller (the two is all not shown) through cable 419, is used for high energy transmission.
If discharge first uncinus 418, then through guide springs 424 positive opening bottoms 4.In case release spring 424, the second uncinuses 422 can tilt around its pivot 428.The curved end 432 of second uncinus 422 is suitable for and rod 410 engagements, thereby makes bottom 4 remain on constrained position (Fig. 6,9).Because second uncinus 422 is by the rotation of axle pivot, then release board 430 no longer flushes on the surface that is installed in bottom 4.Curved end 432 through promoting release board 430, the second uncinuses 422 breaks away from rod 410, thereby bottom 4 can be opened (Fig. 7,10) fully.
