New description: [New technical field] Especially refers to a flexible flashlight. The present invention relates to a flashlight for a lighting tool housing. [Prior Art] In the event of power outages or outdoor activities, the flashlight is a very practical tool. It provides illumination by the power of the battery. Most of the light is small and easy to carry around, making it one of the must-have items for every household. .

The metal housing 10 is connected to the IC board 16, and the bottom cover 12 is connected to the metal housing 10, Depending on the degree of screwing of the bottom cover 12 and the metal casing 11. Thus, when the user tightens the bottom cover 12, the bottom cover 12 and the metal casing 10 are guided, so that the power of the battery can be supplied to the IC board 16. 'In turn, the LED lamp 15 emits a light source. Generally speaking, the ambient state applied to the flashlight is mostly dim or outdoor, and the user's line of sight is less clear, so that the flashlight often collides with the surrounding objects such as the wall surface and falls, the flashlight Suffering from external impact, resulting in a metal hollow housing 10, bottom cover 12, etc. of the flashlight The structure is relatively easy to be uneven, and the flashlight is transmitted through the metal hollow casing 10 and the bottom cover 12 5 M284820 to conduct the battery power to 16, if the impacted portion happens to be mutually conductive, such as a metal hollow shell The body 10 is connected to the ic board 16 or the bottom cover 12 is connected to the metal hollow housing H) 'will affect the power conduction function, affecting (4) the lighting function of the lamp 15, and even can not continue to use; therefore, how to reduce the flashlight due to accident The negative impact of collision or impact will become an improvement issue. [New content] Therefore, (4) of the present invention, that is, providing a flashlight that can effectively prevent electrical disconnection due to impact or fall of an external force. Thus, the flashlight of the present invention having a flexible housing includes a hollow housing for the battery, a light-emitting unit, an electrical conduction unit, and a control switch. The hollow housing is made of a flexible, flexible material and has a first end and a second end. The light emitting unit is disposed at a first end of the hollow casing. The electrically conductive unit is disposed along an inner wall surface of the hollow casing, and one end thereof is electrically connected to the light emitting unit. The control switch is electrically connected to the other end of the electrical conduction unit and the battery, and is controlled by an external force to determine whether to supply power of the battery to the illumination unit. The above and other technical contents, features and effects of the present invention will be apparent from the following detailed description of the preferred embodiments. 2, a preferred embodiment of the present invention includes a hollow housing 21, a light guide cover 22, an illumination unit 23, an electrical conduction unit 24, and a control switch 25. And a set of rings 26. 6 M284820 The hollow casing 21 is a long cylindrical shape made of a flexible material such as a thermoplastic polyacetal elastomer (TPR) and the axial length of the hollow casing 21 is substantially equal to that of a third battery 3 (As shown by the imaginary line, this embodiment uses the third battery as an example to describe the length of the hollow housing 21 to be adjusted according to the type and number of built-in batteries to provide a space for the battery 3 to be accommodated. Referring to FIG. 2 and FIG. 3, the hollow housing 21 has a first end 211, a second end 212, and three strips 216 respectively protruding from the inner wall surface toward the central axis of the hollow housing 21. The second end 212 is connected to an end cap 213. The end cap 213 is pivotally connected to the second end 212 of the hollow casing 21 by an extending arm 214, and the second end 212 can be slidably folded. Further, the inner peripheral surface of the open end portion of the end cover 213 is recessed to form a ring-shaped concave edge 215. The space enclosed by the top end of all the bars 216 is just as good as the volume of the power supply cell 3, and the electrically conductive unit 24 is disposed between the two adjacent bars 216. The end cover 213 is further fitted with a metal guide piece 2131 protruding toward the second end 212 toward the side of the second portion 212 of the hollow casing 21 for guiding the negative electrode of the battery 3. The metal guide piece 2131 of this embodiment has a semi-arc profile in cross section, and its convex surface faces the negative electrode of the battery 3. The light guide cover 22 is left in the first end 211 of the hollow casing 21, and a reflective pigment or a reflective layer is applied to the inner surface of the light guide cover 22. In this embodiment, the light-emitting unit 23 has one (or a plurality of) light-emitting diodes (LEDs) 231, and a circuit board 232 for soldering the light-emitting diodes 231 on one side thereof, and emits light. The diode 23 is placed in the sigma-shaped space of the light guide cover 22, and the light of the light-emitting diode 22 directs the M284820 light of the light-emitting diode to the first end 211 of the hollow body 21. The other side of the circuit board 232 further has a bumping contact 2321 for guiding the positive terminal of the battery 3. The electrically conductive unit 24 has a flexible substrate 241 extending axially adjacent to the inner wall surface of the hollow casing 21, and a plurality of electrically conductive paths 242 pre-embedded in the flexible substrate 241, which are well known in the market. The flexible circuit board (4) squeezing (10) Circit) 0 one end of the conductive path 242 is connected to the circuit board 232 of the light-emitting unit 23, wherein the other end of one conductive path 242 is connected to the metal guide to make the circuit board 232 permeable to metal The guiding piece 2131 leads to the negative electrode of the battery 3, and the other ends of the other two conductive paths 242 are the conduction control switch 25 (which will be described later). Of course, those skilled in the art know that the electrical conduction unit can also be composed of a plurality of wires, and only the metal guide 2131 and the control switch 25 and the circuit board 232 _ electrical conduction can be completed, and + limited to this implementation The example is disclosed. The control switch 25 is disposed in the end cover 213 and located between the metal guide piece 2131 and the bottom wall of the end cover 213. The control switch 25 of this embodiment is a thin film switch having two opposite and spaced conductive films 251, 252 (shown in Figure 6). The two conductive films 251, 252 respectively lead to the other ends of the two conductive paths 242. When the control switch 25 is pressed, the two conductive films 251 and 252 are short-circuited by mutual contact due to an external force, and the circuit board 232 can be short-circuited by the two conductive paths 242 of the electrical conduction unit 24 to know whether the control switch 25 is pressed. The illumination of the light-emitting diode 231 is controlled. Of course, if the control switch 25 is no longer pressed, the two conductive films 251, 252 are restored to be spaced apart from each other and no longer contact each other. In addition, the bottom surface of the end cover 213 of the embodiment 213 is further convexly provided with a bump 2132 so as to be pressed by the bump 2132 (shown in FIGS. 6-7) when the user presses the end cover 213. The switch 25 drives the two conductive films 251, 252 to contact each other. Of course, those skilled in the art will recognize that the control switch 251 can be a generally reversible contact switch that refers to a short circuit when pressed, and returns to an open circuit when not pressed. In addition, the circuit board 232 of the embodiment is provided with a control unit 40 as shown in FIG. 4, which includes a boosting circuit 41 and a driving circuit 42. The boosting circuit 42 is electrically connected to the battery 3 for using the battery. The output voltage of 3 is boosted to a turn-on voltage v〇ut that illuminates the light-emitting diode 231; the drive circuit 42 receives the turn-on voltage Vout and is controlled by the control switch 25 to determine whether to turn on the light-emitting diode 231. The collar 26 is embedded in the interior of the hollow casing 21 adjacent to the second end 212, and one end of the end cap 213 is exposed outside the hollow casing 21 and protrudes radially outwardly from a ring flange 261. The ring flange 261 is snap-fitted into engagement with the annular recess 215 of the end cap 215 to position the end cap 213 at the second end 'as shown in FIG. After the end cover 213 is disposed at the second end 212 of the flashlight 2, as shown in FIGS. 5 and 6, the positive electrode of the battery 3 is connected to the protruding contact 232 of the circuit board 232, and the negative electrode of the battery 3 passes through the metal guide 2131 and the conductive path. 242 (not shown) is connected to the circuit board 232, so that the circuit board 232 can receive the battery 3: power supply ^ with reference to Figure 7, if the user presses the end cover 213 from the outside of the end cover 213 toward the battery ^ ( The direction of the force is as indicated by the arrow in Fig. 7. Since the end cap 213 is soft, it is forced by an external force to form a short (four) shape to drive the two conductive films 251, 251 of the control switch 25 to contact each other and short-circuit, so that the drive The M284820 circuit 42 can be informed that the control switch 25 is pressed via the two conductive paths 242. If the control switch 25 is pressed for the first time or the LED 231 is not working, the circuit board 232 supplies power to the LED 231 to make the LED. When the external force is applied to the end cover 213 to drive the control switch 25 to be short-circuited again, the driving circuit 42 will be turned to the state, and the power supply to the light-emitting diode 231 is no longer supplied, so that it no longer emits light. Therefore, the control switch 25 can be reversed by repeatedly pressing The light-emitting diode 231 is turned on or off. As can be seen from the above description, compared with the conventional flashlight 1, the flashlight 2 of the present invention encounters a strong collision or an impact force falling on the ground. It can be absorbed by the soft hollow casing 21, although the hollow casing 21 is locally twisted at the moment of impact, and the possibility of the electric conduction unit 24 being deformed is extremely high, but both are made of soft materials. It is not easy to break or break directly at the stress formation, and it can recover the shape before unstressed, ensure the integrity of the circuit, and greatly reduce the situation that the LED 231 cannot continue to be bright due to improper use, avoiding the flashlight. 2 The illumination function is interrupted. In summary, the flashlight 2 of the present invention having a flexible casing is coupled to the deformable electrical conduction unit 24 through the flexible hollow casing 21 to prevent the circuit from being interrupted under improper use, and to ensure the illumination unit 23 Continuously providing illumination and loop integrity, thus indeed achieving the objectives of the present invention. The above is only the preferred embodiment of the present invention. When it is not possible to limit the scope of this new implementation, that is, the simple equivalent changes and modifications made by the new patent application scope and the new description content are still within the scope of this new patent.
