Description

[Detailed description of the invention]

The present invention relates to a portable device with a built-in manual charger. For example, in portable radios, etc., dry batteries are normally used as a power source. When the power level drops below a predetermined value, the battery is replaced with a new one.However, if the new battery to be replaced is not available manually, the use of radios, etc. becomes impossible.This should be avoided. If this does not work, you can carry a spare battery with you, but if you are traveling for a long time in an area where batteries cannot be used, you will need a large amount of batteries, which is actually a two-way situation. After digging deeper into the situation, we decided to use a power supply battery from Charitunanno.
Are the generator and generator sump drive device exposed to the outside of the equipment case only when in use? It has a built-in operation handle for the drive unit, and if necessary, turn the operation handle to connect to the generator and charge the power battery. l = (!) We are trying to provide a mobile device that is designed so that In Fig. 1 and 21' +i + of 1+1 ability

a, a gear 5b meshed with the pinion 5a, a pinio 15C integrated with the gear 5b, and a gear 5d meshed with the pinion 5C. 71. These gears are rotatably supported by a gear set L/-1.5θ 5 f placed on the large plate 2. For example, the gear 5d rotates at a speed of about 2 revolutions/second. The teeth 57 (ratio is selected such that when the generator 4 is pressed, the rotor of the generator 4 is rotated at a speed of 3000 revolutions/rotation degree) are connected to the rotating shaft 5d' of the gear 5d. A handle removal plate 7 has a groove 6a' (see Fig. 3) in the diametrical direction, and one ridge is the handle removal plate 7.
It is a No. 7 dollar that is pivotally supported within the groove 6a of the base plate 6 and has a rotatable cylindrical grout 7a at the tip. As clearly shown in FIG. 1, some handles are mounted on the side wall of the device 1 so that the outer end surface of the panel 6 is approximately flush with the side surface of the case. After storing the handle 7 and turning it approximately 180 degrees in the direction of the arrow from the position shown by the solid line and bringing it to the position shown by the dotted line, remove the handle. As shown in the figure, a recessed chamber 1a is formed in which a handle 7 can be accommodated.
The jack 9 is fixed to the board 2'2, and the primary side is connected to the jack 8 with 2V (the side is connected to the power supply battery 3).
When the jack 8 is connected to the commercial power supply, the predetermined DC voltage is 71: connected. A tranos, JO (FIG. 2), which can be applied between the terminals of the power source battery 3, is connected between the power source battery 3 and the input terminals to various circuit devices arranged on the board 2''-, and 71L+I!

If you notice that the tli pressure of 3 has fallen below the predetermined value, bring the noddle to the position indicated by the solid line (6, When the rotor of the generator 40 is rotated at a speed of 3,000 revolutions/rotation via the speed increasing device 5, a power of, for example, 6 V: 5QQmA to IA is generated at the output end. Therefore, if the handle 7 is continued to be rotated for a suitable period of time, the power battery 3 will be sufficiently charged.When charging is thus completed, the handle 7 is stored in the recessed chamber 1a as described above.In this case, The handle 7 is held by a well-known gripping means (not shown) so that it does not accidentally fly out into the room, so the handle 7 does not get in the way of the cell phone. What happens (d,
Moreover, it does not spoil the appearance of the device in terms of design. If you have a commercial power source nearby, you can use the jack 8 and transformer 9 to charge the battery.Generally, in the case of a rechargeable power supply battery, if it is used continuously for one hour, the battery will become over-discharged. However, according to the present invention, since the protection circuit 10 is provided, there is no need to worry about this type of problem, and the battery 3 is always connected. In addition, when the checker button 11 is pressed, the display 12 shows the I of the power battery 3.

If there is no IIL, this results in informing the operator of the need for full IIL, which is extremely convenient in practice. 7a The power source battery can be changed to small/a', and the rliJ'!' operation makes it possible to always use the source battery in the best condition. However, it is extremely portable and can be used to provide equipment, further expanding the scope of use of this type of equipment.
