Description

Portable manual charging device

Technical field

The present application relates to an energy saving device, and more particularly to a portable manual charging device.

Background technique

In modern life, the use of mobile phones is very frequent. Mobile phones are not only a communication tool, but also have many functions. For example, mobile phones have included many consumer payment functions such as banking functions, food, clothing, housing, and transportation. Most external functions in life.

Consumption of mobile phones has always been a global problem. Mobile phone manufacturers around the world are looking for ways to increase the storage capacity of batteries and ways to improve the power consumption of display screens. However, the power consumption of the mobile phone is still very fast, causing mobile phone consumers to often find a place to charge when going out, and often need to bring a power bank, the use of the power bank is also time-limited. If the power of the power bank is exhausted, the mobile phone cannot Meet the normal use of consumers. At the same time, the power bank of the mobile phone must first charge the internal battery of the power bank with external power and a charger before the power bank can store the power and then recharge the mobile phone. Once an uninterruptible outlet is not found, it cannot be used. Power your phone and power bank. For example, in some remote places, if there is no backup power supply, emergencies and emergencies occur, and the mobile phone lacks power and cannot contact the outside world.

There are three types of manual power generation flashlights in the market, one is the hand-held method, one is the hand-cranked method, and the other is the temperature-difference method of the hand. All three methods can only drive the smallest power LED as a temporary faint light to watch. At this time, the LED current is only approximately in the range of 0.01 amps to 0.05 amps, and the maximum output power is only in the range of 0.03 watts to 0.15 watts. However, in general, the minimum charging current of a mobile phone charger is greater than 0.3 amps, and the minimum charging power is at least 1 watt. The minimum rated charging current of the factory charger used by the mobile phone is usually the smallest nominal 0.5 amp and the output power is 1.5 watts. The fast charging type factory charger has a charging current in the range of 1 amp to 3 amps and an output power of 3 watts to Between 10 watts.

Due to the problem of space design, the hand holding method can only be used with magnetically permeable materials for magnetic field transformation and mutual induction power generation for axial coils. The efficiency of this power generation is the lowest among various power generation methods. At the same time, due to the problem of space design, the geared speed-increasing structure of the hand-held method cannot achieve high-speed speed-up, and it cannot meet the voltage demand of magnetic line cutting to generate electricity. In addition, the use of magnetic field power generation must meet the manual speed of humans, and the manual speed of humans is limited. It must have the basic speed of manuals in order to generate large power requirements. Therefore, the manual magnet power generation structure on the market can only be made into the LED flashlight with the lowest efficiency, the output power is only about 0.06 watts, or the radio consumes very little power. There are two types of hand-cranking methods: swing-arm swing method and holding-hand-crank method. The swing-arm swing method is very bulky and is not convenient to carry around. At the same time, both hands need to be grasped and shake like the mainspring. The portable, power-generating structure is also inefficient, and the output power is only about 0.15 watts. At the same time, two hands must be used together. The method of shaking by holding hands is to use gravity vibration to drive magnets or coils to cut magnetic fields with each other to generate current. This method of using gravity vibration is affected by spring force and cannot be fast. At the same time, it can only provide weak power and output. The power is only about 0.06 watts. The power generation method of the handheld temperature difference method has lower power generation, and the temperature difference when holding is completely used to generate electricity from the temperature difference power generation sheet. The temperature difference of the handle cannot achieve a large temperature difference, so the handheld power generation is not a marketable product. The power of the above portable power generation products is very small. They can only drive the LEDs with the lowest power. They are used as flashlights with very low brightness. The brightness is too low to illuminate things clearly, and they cannot be used as external charging products.

In summary, the existing products that can generate electricity manually cannot charge any electrical appliances with a certain power requirement, such as mobile phones, anytime, anywhere.
