Description

Vibration power generation device

The invention belongs to the technical field of electromagnetic induction power generation, and particularly relates to a vibration power generation device. Background technique

A large number of electronic devices such as mobile phones, PDAs, MP3 players, electric toys, and remote controls use DC dry batteries as a power source, which is used in a large amount. In fact, at present, civilian dry batteries are currently the most used and most dispersed battery products, with annual domestic consumption exceeding 8 billion. There are mainly 2 series of zinc manganese and alkaline zinc manganese, and a small amount of zinc silver, lithium batteries and other varieties. The most polluted mercury (HgO) battery was phased out in 1999 and was replaced by a zinc-air battery. Zinc-manganese batteries, alkaline zinc-manganese batteries, zinc-silver batteries, and zinc-air batteries are generally used. All compounds using mercury or mercury are used as corrosion inhibitors. According to the regulations of the nine ministries and commissions on the limitation of mercury content in battery products, zinc-manganese batteries have met the requirements of low-mercury, but most of them produce alkaline zinc and manganese. The battery, its mercury content and the requirements for low-mercury are still relatively large. Since mercury and mercury compounds are highly toxic, the environmental pollution of waste batteries has caused widespread concern in the public, media and environmental management sectors. In the recent past, the domestic voice has been particularly strong, and it seems to have been compared with the treatment of "white" pollution and automobile exhaust. Zinc-manganese and alkaline zinc-manganese batteries are the largest domestic batteries. In addition to mercury pollution, waste batteries also contain other heavy metals such as zinc, manganese and copper. Due to the use of dispersion, recovery is difficult to manage, waste battery recycling costs are large, and there is currently no scientific and economical treatment method. Waste batteries are generally disposed of as domestic waste. Since the treatment of domestic garbage is not the same, the way of pollution is different. When the garbage is composted, the waste battery increases the heavy metal content in the compost crop product. When it is landfilled, it mainly pollutes the water system and the soil near the landfill. When domestic garbage is incinerated, part of heavy metals such as mercury, cadmium, lead, and zinc in the waste battery are discharged into the atmosphere at a high temperature, and some of them become ash and cause secondary pollution.

In addition, in many cases, when the rechargeable battery of these electronic devices is exhausted, the rechargeable power cannot be found in time. With the development of technology, various electronic products are increasingly functioning and power consumption is increasing. On the other hand, in order to reduce the size of these electronic products, manufacturers and consumers are pursuing smaller volumes and lighter. The weight, so that the power supply design is a major bottleneck in the development of such products.

Because designing self-charging devices for these electronic devices has become a research direction, vibrating power generation charging devices have become a focus of research. Patent Document 200420114116. X discloses a vibrating power generation charger which generates electric power by generating a sense by operating a permanent magnet vibrated by an external force in the coil. The vibrating charger mainly uses the vibration mechanism energy of the vehicle to generate electricity during driving, and its volume is generally large, and cannot be built into a small-sized electronic device, and the permanent magnet in the vibrating charger is connected by a spring. When the external vibration is strong, the permanent magnet can generate a large amplitude motion, thereby generating a current. In addition, this vibration charger uses a single The coil is used for power generation, and the power generation efficiency is low. Summary of the invention
