In conjunction with Fig. 3 and Fig. 4, when after case and bag lid 19 and body bag 10 closures, normal open switch contact 66 is often opened left contact 61 and the right contact 62 of Chang Kai along with touch in case and bag lid 19 enters interior round recessed 63 simultaneously, cause normally closed left contact 91 with and the closed energising of normally closed right contact 92.After the case and bag lid 19 on body bag 10 is opened, left case lid closure plate 65 is along with case and bag lid 19 is raised, taken away normal open switch contact 66, normal open switch contact 66 is with often to open left contact 61 separation with the right contact 62 of Chang Kai, causes often to open left contact 61 and often open right contact 62 and recover the state diagram disconnecting.
In conjunction with Fig. 5 and Fig. 6, when after case and bag lid 19 and body bag 10 closures, normally closed switch contact 99 is oppressed retrude by the right case lid closure plate 95 on case and bag lid 19, causes normally closed left contact 91 and the separation disconnection of normally closed right contact 92.After the case and bag lid 19 on body bag 10 is opened, right case lid closure plate 95 is along with case and bag lid 19 is raised, and normally closed switch contact 99 affranchises, and normally closed left contact 91 and normally closed right contact 92 recover closed state diagram.
Bulb D in circuit is placed in illuminating lamp shade 55, and the light emitting diode VL1 in circuit and light emitting diode VL1 are placed in the interior left and right of warning mark 56, and the wire in circuit can pass through between described body bag 10 and case and bag lid 19 and case and bag interior decoration fabric 57; In conjunction with the built-in normal open switch contact 66 of left folding snap close 60 and the built-in normally closed switch contact 99 of right folding snap close 90.
When after case and bag lid 19 and body bag 10 closures, the built-in normally closed switch contact 99 of right folding snap close 90 is along with case and bag lid 19 pushes away slide block disk 97 no longer with normally closed right contact 91 and described normally closed right contact 92 and contacts, and volute spring 89 is compressed accumulation of energy; Be that in circuit, normally closed switch contact 99 disconnects with normally closed left contact 91 and normally closed right contact 92, bulb D does not switch on and does not work; Meanwhile, along with case and bag lid 19 enters into, left plate recess hole 63 contacts with often opening left contact 61 and often open right contact 62 the built-in normal open switch contact 66 of left folding snap close 60 simultaneously, in circuit, often opens left contact 61 and often opens right contact 62 and connect.
By day or bright and clear environment, the 3 pin output low levels of time-base integrated circuit IC, light emitting diode VL1 is lit and flashes; When the night fell, 3 pin of base IC become high level from low level, and light emitting diode VL2 is lit and flashes, and warning mark 56 plays safe warning function, can avoid traffic personal injury to occur.
At no matter daytime or night, when covering case and bag lid 19, normally closed switch S1 is disconnected, and bulb D does not all work, and saves dc-battery GB electricity consumption.
After the case and bag lid 19 on body bag 10 is opened, the built-in normally closed switch contact 99 of right folding snap close 90 is along with case and bag lid 19 leaves slide block disk 97, and the reseting elasticity of volute spring 89 is released slide block disk 97 simultaneously with normally closed right contact 91 and described normally closed right contact 92 and contacted; Be that in circuit, normally closed switch contact 99 is connected with normally closed left contact 91 and normally closed right contact 92, bulb D just switches on and lights; Meanwhile, the built-in normal open switch contact 66 of left folding snap close 60 is often opened left contact 61 and the right contact 62 of Chang Kai along with case and bag lid 19 leaves no longer contact, be in circuit, often to open left contact 61 and often open right contact 62 to disconnect, all no power is shinny for the light emitting diode VL1 in circuit and light emitting diode VL1.
By day or bright and clear environment, photo resistance RG is subject to irradiation and is low resistive state, 6 pin of time-base integrated circuit IC and 2 pin current potentials are during higher than 2/3 dc-battery GB voltage, the 3 pin output low levels of time-base integrated circuit IC, make relay K adhesive, its normally closed interlock K-1 disconnects, and bulb D does not work, using electricity wisely.
When the night fell, RG increases because sensitive volume reduces (even without irradiation) resistance, 6 pin and the 2 pin current potentials of time-base integrated circuit IC are declined, when bipod current potential to 1/3 dc-battery GB voltage, 3 pin of base IC become high level from low level, and relay K is discharged, and its normally closed interlock K-1 is connected, bulb D is lit, and can bring and see the interior article of bag clearly conveniently to people.
Adjust the resistance of potentiometer RP, can change the sensitivity of light-operated circuit action.
