Description

Flashlight {FLASHLIGHT}

The present invention relates to a self-powered flashlight using the induced current generated by the operation of the lever as a power source of the bulb, and more particularly, to a flashlight that induces an induced current when the lever is released and released.

Generally, a flashlight illuminates a desired place by a light bulb that is turned on by using a battery as a power source, and is used for various purposes such as indoor lighting during a power failure and traffic police instructions.

However, the flashlight must always be provided with a battery, and since the discharged battery must be replaced at any time, there is an economic burden due to the purchase of the battery, and there is a cumbersome replacement.

In order to solve this disadvantage, a self-powered flashlight using a current generated by inducing a magnetic field to a coil has been proposed.

Self-powered flashlights are usually configured to generate a current in the induction coil by rotating the magnet when the lever is pulled. However, in the case of releasing the lever, the induced current does not occur, so it is inconvenient to frequently repeat the operation of squeezing and releasing the lever, and the mechanical noise is increased.

A method for solving the disadvantages of the power generation method of the self-powered flashlight has been proposed.

Examples of improvement proposals for self-powered flashlights include Korean Utility Model Publication No. 1999-22605 (Flashlight) and Korean Utility Model Publication No. 1999-33610 (Flashlight).

Korean Patent Application Publication No. 1999-22605, which is an electronic device, is designed to store a battery in a self-powered flashlight and use the battery and the current generated by self-power generation. When discharged, it uses the current generated by self-power generation.

However, this design is not a fundamental solution to solve the shortcomings of the power generation method, but rather the disadvantage that the volume and weight of the flashlight is increased by the battery is housed.

The latter, Korean Laid-Open Utility Model Publication No. 1999-33610, the rack is connected to the lever via a pivot means and formed in a substantially depressed shape while the front and rear gear parts are formed on opposite sides, respectively, and the endless ends are formed; It is installed between the gear portion of the rack and is connected to the magnet through the gear train is configured to include a pinion for rotating the magnet.

According to this, when the lever is pulled, the pinion is engaged with the forward gear part of the rack, and if the lever is released, the pinion is engaged with the backward gear part of the rack so that the pinion is rotated in the same direction when both the lever and the lever are released.

According to Korean Utility Model Publication No. 1999-33610, the problem of the power generation method by rotation is solved, but the following problems occur.

As the rack is moved laterally by the pivot means, the forward gear portion or the reverse gear portion is configured to be engaged with the pinion. The pinion may not rotate normally due to the deformation due to the production error and wear of the pivot means. The magnet may not rotate as well. On the other hand, high precision machining is required to solve this problem, there is a disadvantage that the productivity is low.

When the lever is completely grasped or fully released, the pinion is placed at the end of the rack formed at both ends of the rack so that the pinion is continuously rotated for a short time without stopping and the power generation is continued without continuously holding and releasing the lever. Infants are weak and unable to pull the lever completely, so its utility is low.

In addition, although the generated current is to be charged in the storage battery, the current generated by the rotation of the magnet is an alternating current, and the bulb is theoretically impossible because it uses a direct current.

The present invention is designed to solve the problems described above, and to provide a flashlight that can be produced through simple and simple processing, as well as the induced current is generated both when the lever is released and released. have.

Another object of the present invention is to allow the magnet to continue to rotate without stopping even if the grip force is weak, such as women, infants.

As shown in Figure 1 and 2, the flashlight according to the present invention (100), the case 10, the lever 10 is installed in the case 10 and manipulated to generate an induced current, and the lever 20 Induction current generating means for generating induction current both when releasing and releasing), rectifier 1 for converting the AC current generated in the induction current generating means into direct current, and the direct current switched by the rectifier 1 A capacitor accumulating the light, a light bulb L1 receiving the DC current converted by the rectifier 1, and a mobile phone emergency power supply jack J; It comprises a mode switching switch (2) for changing the contact point so that the current generated by the induction current generating means is applied to the bulb (L1) or mobile phone emergency power supply jack (J).

Hereinafter, each configuration will be described in detail.

As shown in FIG. 1, the case 10 includes a left and right side plate 11 and 12 and a left and right side plate 11 and 12 formed of a symmetrical shape and coupled to each other to form a hollow portion having an open front therein. It consists of a header 13 detachably coupled to the front part. Then, the back of the case 10 is connected to the wrist strap string 14, the rear side of the locking pin 15 for attaching and fixing the lever 20 to the case 10 is rotatably coupled.

1 and 2, one end of the lever 20 is rotatably installed through the hinge pin 21 and the torsion coil spring 22 inside the case 10, and the other end thereof. While protruding to the outside of the case 10, the curved rack 23 is formed to extend substantially vertically on one surface, the bent portion is formed to facilitate gripping on the rear surface.

As shown in FIGS. 2 and 3, the induction current generating means is provided with a plate 30 fixed to the case 10 and rotatably installed on one surface of the plate 30, while the upper portion is opened therein and has a peripheral portion. A conductor disc 40 having a rotating body mounting hole 42 in which a ratchet-shaped gear part 41 inclined in one direction is imprinted thereon, and a magnet 50 coupled to a lower portion of the conductor disc 40; , Consisting of an induction coil 51 installed at an outer portion of the conductor disc 40 and upper and lower gears, is rotatably installed in the case 10, and the first pinion 61 is engaged with the rack 23. The two-stage drive pinion 60 (shown in FIG. 2) and the fixed shaft 43 installed in the rotor mounting hole 42 of the conductor disc 40 are rotatably coupled to each other and are formed in an approximately elliptical shape. Shaft grooves 71 are formed at both ends of the driven pinion 72, and the driven pinions 72 meshed with the second pinion 62 of the drive pinion 60 have an upper portion. Rotating body 70 and protruding rotatably coupled to the shaft groove 71 of the rotating body 70, the rotary guide for forcibly rotating the conductor disc 40 in accordance with the operation of the lever ( 80).

The induction current generating means will be described in more detail.

As shown in FIGS. 3 and 4, the rotating body 70 in which the rotary guide 80 is inserted into the shaft groove 71 is fitted to the fixed shaft 43 of the conductor disc 40. 80 is inserted such that its free end faces the valley 41a of the ratchet gear 41.

Rotation guide 80 which is rotatably installed in the shaft groove 71 of the rotor 70 via the shaft 81 has both the conductor disc 40 in the same direction when the lever 20 is removed and placed. Let it rotate

When the lever 20 is gripped, the rotation guide 80 is rotated together with the rotation body 70, and the free end of the rotation guide 80 is valleys 41a of the ratchet-shaped gear part 41 of the conductor disc 40. ) Is rotated forcibly while pushing the conductor disc 40, and, on the contrary, when the lever 20 is released, the rotation guide 80 moves in the opposite direction as when the lever 20 is removed together with the rotor 70. The conductive disc 40, which is rotated but rotated by inertia, because the free end, which is inserted into the valley 41a of the ratchet gear 41, passes over the inclined portion 41 b of the ratchet gear 41. Does not constrain the rotation.

As shown in FIG. 2, the rectifier 1 converts the alternating current generated from the induction coil 51 into a direct current capable of supplying the bulb L1 and the emergency power supply jack J of the cellular phone.

Capacitors use ultra-high capacity capacitors, called supercapacitors 3, capable of storing high-speed, high-capacity electrical energy at a short moment by holding the lever.

The mode changeover switch 2 selects the bulb mode and the power storage mode. That is, the contact point changes according to the state of the mode switch 2 so that the DC current passing through the rectifier 1 is applied to the bulb L1 or the mobile phone emergency power supply jack J.

On the other hand, the flashlight 100 according to the present invention is configured to adjust the angle of the light irradiated from the light bulb (L1).

As shown in FIG. 2, the bulb housing 90 in which the bulb L1 is screwed is installed to slide back and forth along the guide rail 16 formed in the case 10, and one side of the bulb housing 90. The irradiation angle adjusting knob 91 which is forward and backward along the knob guide long hole 17 of the case 10 is integrally formed. That is, when the irradiation angle adjusting knob 91 is moved back and forth, the bulb L1 is moved back and forth along the guide rail 16 together with the bulb housing 90, so that the irradiation angle of light is reduced or increased.

In addition, an accommodating part in which the preliminary bulb L2 is accommodated may be formed in the reflection plate 18 of the case 10.

Light bulbs L1 and L2 are preferably light emitting diodes (LEDs). Since the general electric bulb consumes a lot of power, the operation of holding and releasing the lever 20 must be continuously performed in order to continuously light the general electric bulb. However, since the power consumption is small while the LED maintains sufficient brightness, the lever 20 is moved. The duration of the lighting is long even with one operation. Therefore, the LED is continuously turned on even when the lever 20 is intermittently gripped and released.

Referring to the operating state of the flashlight according to the present invention configured as described above are as follows.

As shown in FIG. 6A, when the lever 20 is gripped, the lever 20 is rotated about the hinge pin 21 (shown in FIG. 2) while being inserted into the case 10 so that the rack 23 is inserted into the case 10. The drive pin 60 is rotated in the clockwise direction when the driving pin 60 is based on the drawings by the linear motion of the rack 23.

As the driven pinion 72 engaged with the second pinion 62 of the drive pinion 60 rotates, the rotor 70 mounts the rotor mounting hole of the conductor disc 40 about the fixed shaft 43. 42) Rotate counterclockwise inside.

When the rotating body 70 is rotated, the rotation guide 80 is rotated toward the ratchet gear 41 by the centrifugal force toward the ratchet gear 41, and its free end of the ratchet gear 41 is rotated. Inserted into the valley 41a, the inclination of the front of the valley 41a is very urgent so that the rotation guide 80 is rotated counterclockwise while pushing the conductor disc 40 without falling out of the valley 41a.

The magnet 50 is rotated together with the conductor disc 40 to generate a magnetic field, and the magnetic field is induced by the induction coil 51 to generate an alternating current in the induction coil 51.

Since the bulb L1 uses a direct current as a power source, the generated alternating current is converted into direct current through the rectifier 1 and applied.

As described above, induction current is generated while holding the lever 20, and the flashlight according to the present invention, even when the lever 20 is held, the magnet is rotated in the same direction by inertia, so that the induced current is generated without a break. Characterized in that can be.

That is, as shown in FIG. 6B, when the lever 20 held by the lever 20 is released, the lever 20 is returned to its original position by the restoring force of the torsion coil spring 22 (shown in FIG. 2), that is, the outside of the case 10. As the lever 20 is protruded, the rack 23 is linearly moved in the reverse direction, and the driving pinion 60 is rotated counterclockwise.

The rotating body 70 is rotated clockwise by the drive pinion 60 so that the rotating guide 80 also rotates clockwise. In this case, the rotating guide 80 is a ratchet type of the original disc 40. The inclination part 41b of the gear part 41 is crossed, and the conductor disc 40 is continuously rotated by the inertia in the immediately moving direction (counterclockwise direction which was rotated when the lever 20 was removed).

As the magnet 50 rotates together with the conductor disc 40, an alternating current is generated in the induction coil 51 as in the case of releasing the lever 20. The alternating current is converted to direct current via the rectifier 1.

The induced current generated while holding and releasing the lever 20 is directly applied to the bulb L1 or stored in the supercapacitor 3 depending on the selection mode.

When the bulb mode is selected by the mode changeover switch 2, the DC current switched through the rectifier 1 is applied to the bulb L1 and the bulb L1 is turned on.

Then, when the power storage mode is selected by the mode switching switch 2, some of the DC current switched through the commutator 1 is stored in the supercapacitor 3, and the rest is applied to the mobile phone power supply jack (J).

The supercapacitor 3 stores a large amount of current in a short time while holding the lever 20. The induced current induced in the induction coil 81 may vary depending on the number of coils wound and the strength of the permanent magnet. However, if the operation of holding and releasing the lever 20 continues, a current of about 3 to 4 V is sufficiently maintained. It can be used as an emergency power supply for cell phones powered by a voltage of about 3.6V.

When the power supply plug (P) of the mobile phone is plugged into the jack (J), a DC current is supplied to the power supply of the mobile phone through the plug (P) to use the mobile phone.

Meanwhile, the distance of light emitted from the light bulb L1 may be adjusted according to the position of the object to which light is to be irradiated. As shown in FIG. 2, when the irradiation angle adjusting knob 91 is moved forward or backward, the irradiation angle adjusting knob 91 is moved forward or backward along the knob guide hole 17 and together with the irradiation angle adjusting knob 91. The bulb housing 90 is advanced or retracted so that the irradiation distance of the light is far or near.

When the flashlight 100 is not used, the lever 20 is interposed between the locking pins 15 and the lever 20 is attached to one surface of the case 10 by attaching the lever 20 to one surface of the case 10. Make sure that (20) does not interfere.

Flashlight using the self-developed principle according to the present invention can be used for various purposes.

As shown in FIG. 7, the case 10 includes a body 19 in which all the operating parts such as the lever 20, the pinion, the conductor disc and the bulb L1 are installed, and the light emitted from the bulb L1. It is formed by separating the head 19A made of a transparent material so that it can be irradiated. Screws are formed on the body 19 and the head 19A, respectively, and the heads 19A are screwed to the body 19 to be coupled.

Therefore, as shown in FIG. 7, when the head 19A of the general flashlight is combined, it can be used at night time during power failure, and as shown in FIG. 8, the head 19B, which is colored with a red color, is combined. It can be used as a safety indicator or indicator used by traffic police at night.

Therefore, the conductor disc 40 does not restrain the rotation of the conductor disc 40 when the rotation guide 70 forcibly rotating the conductor disc 40 when the lever 20 is released. ) Is continuously rotated in the same direction as when the lever 20 is removed by the inertia to maintain the state of the immediately preceding movement, so that the induced current is always generated.

Further, even when the lever 20 is not completely pulled out, the rotation guide 80 does not restrain the rotational force due to the inertia of the conductor disc 40, so the conductor disc 40 continues to rotate without being stopped.

As described above, according to the flashlight according to the present invention, the induction current is continuously generated while the lever is operated without rest, thereby improving the reliability as a self-powered flashlight.

And, even if the lever is not pulled completely, the magnet is continuously rotated so that women, infants with weak grip force can be used without difficulty, thereby increasing the utility of the product.
