The specific embodiment
As shown in Figure 2, the preferred embodiment of flashlight 2 of the present invention comprises: a hollow housing 21, a leaded light lampshade 22, a luminescence unit 23, an electrical conduction unit 24, a gauge tap 25, and a collar 26.
This hollow housing 21 is by the pliability material, the oval tubular of making as thermoplastic polyester elastomer (TPR), and the axial length of hollow housing 21 roughly is equal to No. three batteries 3 (shown in imaginary line, present embodiment is to be the example explanation with No. three batteries, but the size of hollow housing 21 can be adjusted with built-in battery variety and quantity) length, to provide battery 3 ccontaining space.
Cooperate shown in Figure 3ly, this hollow housing 21 has one first end 211, one second end 212, and three respectively by internal face toward the outstanding blend stops 216 of the central axial direction of hollow housing 21.This second end 212 is provided with an end cap 213, and this end cap 213 is pivoted to second end 212 of this hollow housing 21 by an adjutage 214, and can cover second end 212 with starting.
In addition, the open end inner peripheral surface of this end cap 213 hollowly forms a circular recessed edge 215.The spatial dimension that all blend stop 216 tops institute corrals go out just can be held for the volume of battery 3, and this electrical conduction unit 24 then is arranged on wherein the space of 216 of two adjacent blend stops.End cap 213 is more set the metallic laminas 2131 that one day, second end, 212 directions protruded out towards second end, 212 1 sides of hollow housing 21, is used for connecting the negative pole of battery 3.The cross section profile of present embodiment metallic laminas 2131 generally is half arc, and its convex surface is towards the negative pole of battery 3.
This leaded light lampshade 22 is into horn-like and is positioned at first end 211 of hollow housing 21, and in the inner surface coating reflective pigment of this leaded light lampshade 22 or paste reflector layer.
In the present embodiment, this luminescence unit 23 has (also can be an a plurality of) light emitting diode (LED) 231, and supply aforementioned light emitting diode 231 to weld a circuit board 232 of being located on its one side, and light emitting diode 231 is sleeved in the horn-like space of leaded light lampshade 22, by first end 211 of leaded light lampshade 22 with the light guiding hollow housing 21 of light emitting diode.The another side of circuit board 232 has more a protruding contact 2321 for the positive pole that connects battery 3.This electrical conduction unit 24 has an axially extended flexible base plate 241 of internal face that nestles up this hollow housing 21, and many conductive paths 242 that are embedded in advance in the flexible base plate 241, just known on the market flexible circuit board (Flexible Printed Circit).
One end of aforementioned conductive path 242 connects the circuit board 232 to luminescence unit 23, wherein the other end of a conductive path 242 connects to metallic laminas 2131, connect battery 3 negative poles to allow circuit board 232 can see through metallic laminas 2131, the other end of two other conductive path 242 is to connect gauge tap 25 (its effect repeats after holding).Certainly, those skilled in the art only need be able to finish being electrically conducted of 232 of metallic laminas 2131 and gauge tap 25 and circuit boards and get final product when knowing that electrical conduction unit 24 also can be made of many leads, are not limited to present embodiment and disclose.
Gauge tap 25 is arranged in this end cap 213 and is positioned between the diapire of metallic laminas 2131 and end cap 213.The gauge tap 25 of present embodiment is a thin film switch, has two relatively and conductive film separately 251,252 (being shown in Fig. 6), and two conductive films 251,252 connect the other end of two conductive paths 242 respectively.When gauge tap 25 is pressed, two conductive films 251,252 are in contact with one another short circuit because of the external force effect, circuit board 232 can utilize two conductive paths, 242 short circuits of electrical conduction unit 24 whether to know whether gauge tap 25 is pressed, and then controls flickering of light emitting diode 231.Certainly, when no longer being pressed as if gauge tap 25, two conductive films 251,252 revert to the space and no longer are in contact with one another.In addition, the diapire face of the end cap 213 of present embodiment more convexes with a salient point 2132, so that the user when pushing end cap 213, can compress gauge tap 25 by salient point 2132 (being shown among Fig. 6 to Fig. 7) and be in contact with one another to order about two conductive films 251,252.Certainly, those skilled in the art are when knowing, but gauge tap 25 can be general return type touch switch, refers to short circuit when pushing, and when not pushing, then revert back to open circuit.
In addition, the circuit board 232 of present embodiment is provided with a control module 40 as shown in Figure 4, it comprises a booster circuit 41 and one drive circuit 42, and this booster circuit 41 is electrically connected with battery 3, boosts to a conducting voltage Vout that can light light emitting diode 231 in order to the output voltage with battery 3; This drive circuit 42 is accepted 25 controls of this conducting voltage Vout and suspension control switch, whether to determine conducting light emitting diode 231.
This collar 26 is the positions that are embedded at hollow housing 21 inner contiguous second ends 212, end of its contiguous end cap 213 exposes hollow housing 21 outside also more radially one ring flange 261 of projection outward, the circular recessed edge 215 of this ring flange 261 and end cap 215 tightly inlay card end cap 213 is positioned at second end 212, as shown in Figure 5.
After end cap 213 lids are located at second end 212 of flashlight 2, as Fig. 5 and Fig. 6, the positive pole of battery 3 connects the protruding contact 2321 to circuit board 232, the negative pole of battery 3 connects to circuit board 232 through metallic laminas 2131 and conductive path 242 (not indicating among Fig. 5 to Fig. 6), allows circuit board 232 can receive battery 3 power supply of supplying.Cooperate shown in Figure 7, if when the user oppresses end cap 213 (application of force direction such as Fig. 7 arrow indication) from end cap 213 outsides toward battery 3 directions, because this end cap 213 is a soft plastic, force down short time set being subjected to external force, be in contact with one another and short circuit with two conductive films 251,252 that order about gauge tap 25, allow drive circuit 42 know that gauge tap 25 is pressed through two conductive paths 242, if gauge tap 25 is for pushing for the first time or light emitting diode 231 is not worked, circuit board 232 gives light emitting diode 231 with supply power, makes light emitting diode 231 conductings and luminous.
And ought apply external force once more on end cap 213, order about gauge tap 25 once more during short circuit, will make drive circuit 42 transitions then no longer supply power give light emitting diode 231, make it no longer luminous.Therefore, can control light emitting diode 231 repeatedly and light or extinguish by pushing gauge tap 25 repeatedly.
As shown in the above description; compare down with existing flashlight 1; flashlight 2 of the present invention meets with powerful collision; or drop in ground impulsive force; the strength of its generation can be absorbed by soft hollow housing 21; though bird caging can take place in bump this hollow housing 21 of moment; cause the askew possibility of selling off shape in this electrical conduction unit 24 high simultaneously; but because both make by flexible material; be not easy in directly fracture or damaged of stress formation place, and can reply not stressed preceding form voluntarily, guarantee the integrality in loop; significantly reduce because of improper use causes light emitting diode 231 and can't continue shinny situation, avoid flashlight 2 irradiation functions to interrupt.
Conclude above-mentioned, flashlight 2 of the present invention sees through the deformable electrical conduction of soft hollow housing 21 collocation unit 24, prevent to cause under the improper operating position problem of loop interruption, guarantee that luminescence unit 23 continues to provide illumination and circuit complete, thereby can reach purpose of the present invention really.
