Power generation crutches and electrical equipment mounted on the crutches

The present invention relates to a power generating crutches and an electrical device mounted to the crutches, and more particularly to a power generating crutches that can be used as mountaineering rafts and that can be used for outdoor activity lighting and electrical devices mounted to the crutches.

Pressed, crutches are common walking aids in daily life, and crutches are often used to assist walking in mountaineering or field activities. Since the traditional walking sticks are all auxiliary equipment, there is no other function. When people go out for hiking or hiking, they often encounter no lights around at night, which makes the line of sight limited and difficult to move, and most people do not have the habit of carrying a flashlight with them. The lighting function of the mobile phone cannot be used for a long time because it is too power-hungry. .

In order to overcome the above shortcomings, there are products with a combination of crutches and flashlights on the market. However, the power source of the crutches with flashlights is still powered by batteries, so the use time is limited, and when there is nowhere to charge when climbing or in the wild, when the battery After the power consumption is completed, it cannot be used any more, which is quite inconvenient.

In order to solve the aforementioned shortcomings of the conventional crutches, some of the crutches having the power generation function and the addition of the lighting device appear, for example, the Republic of China Patent Announcement No. M400232 "Shock-proof power storage lighting warning stick device" discloses a cane with a power generating device. The structure comprises an upper rod and a lower rod, the upper rod and the lower rod are nested with each other, and can be relatively reciprocally displaced up and down, and a compression spring is arranged between the upper and lower rods, so that the upper and lower rods are pressed Can be pushed back to the pressure before being pressed by the spring force of the spring relative position. The upper rod and the lower rod are respectively provided with an induction coil and a magnet column. When the upper and lower rods are relatively reciprocally displaced, the magnet column is relatively reciprocally displaced in the induction coil, thereby causing the induction coil to generate a current. The stick is also provided with a lighting device and a warning device, and the current generated by the power generating device is used as a power source.

The conventional cane with a power generating device, although having its own power generating capability, uses a power generating device that generates current using a linearly moving coil and a magnet column. However, since the inner space of the cane is narrow, the number of coils of the induction coil used is also limited, so the amount of current that can be generated in each stroke of the magnet column and the coil relative to each other is quite limited. At the same time, since the coil and the magnet column are respectively linked with the upper and lower rods of the cane, each relative movement of the upper and lower rods can only drive the coil and the magnet column to generate a relative reciprocating displacement, so that the coil is generated. In the case where the electric current is limited and the number of actuations cannot be increased, the conventional cane with a power generating device has a relatively limited power generation capacity and can only be used for a low-power lighting device.

In addition, this type of conventional power generation cane is fixedly disposed on a cane and cannot be used separately, so that the convenience of use is limited, and the current generated by the power generation device of the power generation can only be used for its own illumination device. Use, can not be used for other electronic products.

However, when hiking in the wild, mobile phones, wireless talkers, satellite locators and other electronic products are often used. These electronic products also rely on battery power. Therefore, if the power cane can only be supplied to its own electrical device, then Will limit its functionality.

Therefore, considering the two problems of lighting and charging, if the emergency lighting function and the mobile power source can be combined with the crutches, it is not only easy to carry, but also can be improved, and the crutches can generate electricity by themselves, and can improve the lighting time. Providing emergency charging of 3C products will greatly enhance its functions.

Therefore, how to design a crutches that integrate lighting functions and generate electricity by themselves to overcome the above problems has become one of the important topics in this technical field.

A main object of the present invention is to provide a power generating crutches incorporating a power generating device capable of converting kinetic energy generated by a user's walking into electric power as a power source of the lighting device and charging other electronic products.

The present invention provides a power generating crutches and an electrical device mounted on the crutches. As shown in FIG. 1 , a first embodiment of the present invention includes a cane body 10 , a power generation module 20 mounted in the cane body 10 , an elastic device 30 , and an electrical device mounted on the top end of the cane body 10 . Device 40.

The crutches body 10 is a rod-shaped structure including a first rod body 11 and a second rod body 12. In this embodiment, the first rod body 11 and the second rod body 12 are preferably, but not limited to, a circular rod body. The first rod body 11 is a hollow sleeve and has a receiving space 111 at the center thereof. The power generating module 20 can be received in the accommodating space 111, and the second shank 12 is inserted into the accommodating space 111 from the opening of the accommodating space 111 at the bottom of the first shank 11.

The top end of the second rod body 12 is slidably fitted in the accommodating space 111 of the first rod body 11 and is linearly reciprocally displaceable in the accommodating space. The bottom end of the second rod body 12 protrudes from the outer side of the accommodating space 111 of the first rod body 11 , and a buffering member 121 is disposed at an end of the second rod body 12 away from the first rod body 11 . The intermediate cushioning member 121 is a sleeve made of rubber and fits over the bottom end of the second shaft 12 to serve as a buffer for the contact between the second shaft 12 and the ground, and increases the contact between the cane body 10 and the ground. Friction.

A first blocking portion 112 is disposed in the accommodating space 111 of the first rod body 11 at a position above the top end of the second rod body 12, and the second rod body 12 is nested at one end of the accommodating space 111. There is a second stop 122. The elastic device 30 is disposed in the accommodating space 111 , and the two ends abut against the first stopping portion 112 and the second stopping portion 122 respectively. As shown in FIG. 2A and FIG. 2B, in this embodiment, the elastic device 30 is used as a compression spring (of course, the elastic spring can be replaced by various types of equivalent components such as an excellent rubber, a rubber spring, a gas spring, and a hydraulic spring). And the two ends thereof are mortgaged by the first stopping portion 112 and the second stopping portion 122, so that when the second rod body 12 of the cane body 10 is subjected to a pressure, it is approached toward the first rod body 11 (for example, using When the person walks, when the crutches are supported on the ground, a compression action can be generated to compress the elastic device 30, so that the elastic device stores kinetic energy (as shown in FIG. 2B). Shown). When the aforementioned pressing force for forcing the second rod body 12 toward the first rod body 11 to disappear (for example, when the user lifts the crutches body 10 while walking, the second rod body 12 is separated from the ground), the elastic device 30 is able to push the second rod 12 in a direction away from the first rod 11 by its elastic force, and return to a position before it is pressed to generate the compression action (as shown in Fig. 2A).

Therefore, when the user assists walking with the crutches body 10 of the present invention, the second shaft 12 continuously contacts the ground, and then the repetitive motion of the second shaft 12 is continuously generated to the The first rod body 11 approaches and compresses the elastic device 30, and then the elastic device 30 releases the elastic force to push the second rod body 12 back to the linear reciprocating displacement of the starting state of the motion, and the power generating module 20 of the present invention transmits The kinetic energy generated by the relative motion between the second rod 12 and the first rod 11 serves as a source of power for power generation.

As shown in FIG. 2A, FIG. 2B and FIG. 3, the power generation module 20 of the present invention includes a base 21, a generator 22, a rack 24, and a transmission gear set 25. In this embodiment, the base 21 is a fixed plate body, the generator 22, and the transmission gear set 25 are respectively disposed on the base 21, and are mounted on the first rod through the base 21 The inside of the accommodation space 111 of the body 11. The rack 24 is oppositely mounted on the second rod 12, and is capable of generating a relative reciprocating displacement with the generator 22 as the reciprocating motion of the second rod 12. The transmission gear set 25 is connected between the rack 24 and a driving shaft 221 of the generator 22, so that the driving shaft 221 can be driven by the rack 24 to drive a rotor inside the generator 22. Rotation with the stator (not shown) produces a current output. It should be noted here that in the embodiment, the power generation module 20 mounts the generator 22 on the first rod 11 and the rack 24 is mounted on the second rod 12, but in actual use, the teeth The position where the strip 24 and the generator 22 are mounted can be adjusted to each other and can achieve the same purpose.

In this embodiment, the power generating module 20 uses a gear transmission manner to drive the driving shaft 221 of the generator to the rack 24 for linearly reciprocating the rack 24. Shift into a rotary motion. In this embodiment, the transmission gear set 25 includes: a terminal gear 29 fixed to the drive shaft 221 of the generator 22; an initial transmission gear 26, the initial transmission gear 26 It is disposed on a first rotating shaft 261 and is engaged with the rack 24 so that the initial transmission gear 26 can be driven by the rack 24 to generate a rotating motion. A first intermediate gear set 27 and a second intermediate gear set 28 are further disposed between the initial transmission gear 26 and the terminal gear 29 to enable the terminal gear 29 to be driven to rotate by the initial transmission gear 26.

In this embodiment, the transmission gear set 25 is a speed increasing gear set, that is, the ratio of the speed of the terminal gear 29 to the initial transmission gear 26 is greater than 1, that is, the rotational movement of the initial transmission gear 26, through the transmission After the first intermediate gear set 27 and the second intermediate gear set 28 drive the terminal gear 29, the rotational speed of the terminal gear 29 will be greater than the rotational speed of the initial transmission gear 26.

In order to achieve the purpose of making the transmission gear set 25 a speed increasing gear set and reducing the volume of the power generating module 20 so as to be accommodated in the accommodating space 111, the transmission gear set 25 of the present invention adopts a multi-stage type. The design of the gear set is as shown in FIG. 2A and FIG. 3 . Among the transmission gear set 25 , the first intermediate gear set 27 includes a first intermediate rotating shaft 271 and a first driven gear 272 , the first driven gear The 272 series and the initial transmission gear 26 are coupled to each other, and the number of teeth of the first driven gear 272 is smaller than the number of teeth of the initial transmission gear 26, and a first transmission gear 273, the first transmission gear 273 and the first passive The gear 272 is coaxially disposed on the first intermediate shaft 271, so that when the first driven gear 272 rotates, the first transmission gear 273 also rotates together. The second intermediate gear set 28 includes a second intermediate shaft 281 and a second driven gear 282. The second driven gear 282 and the first transmission gear 273 are coupled to each other, and the number of teeth is smaller than the first transmission gear. a number of teeth of 273, and a second transmission gear 283, the second transmission gear and the second driven gear 282 are coaxially disposed on the second intermediate shaft 281, and the second transmission gear 283 and the generator 22 are driven The terminal gears 29 on the rotating shaft 221 are coupled to each other, and the number of teeth of the second transmission gear 283 is larger than the number of teeth of the terminal gear 29.

Therefore, in the transmission gear set 25 of the present invention, when the initial transmission gear 26 drives the first intermediate gear set 27, since the number of teeth of the first driven gear 272 is smaller than the number of teeth of the initial transmission gear 26, the first heavy weight is generated. When the first intermediate gear set 27 drives the second intermediate gear set 28, since the number of teeth of the second driven gear 282 is smaller than the number of teeth of the first transmission gear 273, a speed amplification effect is again generated; In principle, when the second intermediate gear set 28 drives the terminal gear 29, the number of teeth of the terminal gear 29 is smaller than the number of teeth of the second transmission gear 283, so that a speed amplification effect is again generated.

If represented by a mathematical formula, assuming that the number of teeth of the initial transmission gear 26 is n1, the number of teeth of the first driven gear 272 is n2, the number of teeth of the first transmission gear 273 is n3, and the number of teeth of the second driven gear 282 is N4, the number of teeth of the second transmission gear 283 is n5, and the number of teeth of the terminal gear 29 is n6, then the combined transmission ratio N of the transmission gear set 25 will be: (n1/n2)X(n3/n4)X( N5/n6).

It can be seen from the above formula that the transmission gear set 25 of the present invention can generate a high-speed rotation speed amplification effect by the above-described gear combination method. For example, the gear ratio n1/n2 of the initial transmission gear 26 and the first driven gear 272 is 5 When the gear ratio n3/n4 of the first transmission gear 273 and the second transmission gear 282 is three times, and the gear ratio n5/n6 of the second transmission gear 283 and the terminal gear 29 is also three times, the terminal is The speed ratio N of the gear 29 compared to the initial transmission gear 26 will be up to 45 times. That is, when the initial transmission gear 26 is driven to rotate by one rotation of the rack 24, the terminal gear 29 will generate 45 rotations, thereby producing a high magnification action amplification effect.

Since the power generation module 20 of the present invention must be able to be accommodated in a limited space inside the cane, the volume of the generator 22 is limited, and the power generation thereof is rather limited. In addition, the power generating module 20 drives the generator 22 to generate a linear reciprocating displacement of the rack 24 by a relative movement between the first rod 11 and the second rod 12 to generate a linear reciprocating displacement within a limited range. The current must therefore be amplified by the transmission gear set 25 to amplify the rotational speed of the initial transmission gear 26. By increasing the rotor rotational speed of the generator 22, the present invention enables the use of a small-sized generator 22 and utilizes the rack 24 A limited range of motion can also generate a large amount of current, and can provide sufficient power for the electrical device 40 of the present invention and other external electronic devices external to the electrical device 40 of the present invention.

The charging circuit 442 includes at least one voltage stabilizing unit and a power-off protection unit (not shown) for outputting the transformer. The current is adjusted to a voltage suitable for charging the battery unit 441, and the charging is stopped when the battery unit 441 is fully charged, thereby preventing the battery unit from being overcharged and damaged. The discharge circuit 443 is electrically connected to the battery unit 441. The discharge circuit 443 has a booster circuit and a current limiting circuit (not shown) for boosting the output current of the battery unit 441 to the illumination device 41. The voltage required by the power output connector 43 is stable and the amount of current output is stabilized. set.
