Description

Wearable automatic charging device

The present invention relates to an automatic charging device that can be worn on a body such as a wrist or ankle, and more specifically, it can be worn on a body such as a wrist or ankle in the form of a bracelet or a band worn on the ankle. It relates to a wearable automatic charging device having a magnet that flows according to the movement and a coil that generates an induced electromotive force by the magnet to automatically generate electric energy when the body moves.

2. Description of the Related Art With the rapid development of information communication technology, portable electronic devices have been developed and commercialized. In particular, recently, a smart phone capable of executing various application programs by installing a program and accessing the Internet through a WIFI network or a mobile communication network, by simply breaking the concept of a mobile phone that simply makes or receives calls and sends and receives SMS messages. This is spreading rapidly, and in addition, the portable tablet PC is also in a trend of rapidly spreading its use population.

If the smartphone is described as an example, the number of users is rapidly increasing due to the advantages of the smartphone being able to access the Internet to search a map, search for news in real time, and install a securities program to enable real-time transactions. .

In addition, the smart phone has been developed at a high speed and has been improved in performance, and not only a simple call and text message transmission, but also various office programs can be installed to allow users to perform word work.

On the other hand, since the smart phone and tablet PC as described above are portable devices, periodic charging is essential, and the consumption time of the battery continues to increase due to the high performance of the devices.

However, there is currently no means to supply power to the information communication device even in an environment in which there is no external power when the battery of a portable information communication device such as a smartphone or tablet PC is discharged. In addition, it is currently in a situation where a power generation device that can be used as a portable device cannot be provided because it is capable of generating electric energy through its own power generation function to supply power to a smartphone, tablet PC, LED, etc.

In addition to portable information and communication devices such as smartphones and tablet PCs, products that use electricity, such as heating pads with built-in electric heaters or portable fans, cannot function properly when battery power is exhausted. In particular, it is effective to use a heating pad that uses an electric heater as a heating element when working outdoors for a long time, such as at a construction site or at a stall in winter, but it is difficult to drive the electric heater for a long time with a small battery because of the high battery consumption. have.

Korean Patent Publication No. 2010-0025611 discloses a wearable generator that can be automatically charged by generating electricity according to a user's movement by wearing it on a body such as an arm or leg.

However, in the wearable generator, the first movable body provided with a magnet is mounted on any part of the body, and the second movable body provided with a coil for generating electrical energy by an induced current and a rechargeable battery for storing electrical energy is different from the body. Because it is mounted on the part, it is not only inconvenient to wear, but also generates electricity by the cross movement between the first moving body and the second moving body. Therefore, if the cross movement speed is fast, the amount of induced current is small and it cannot produce enough electric energy, so it cannot be put into practical use there is a problem.

The object of the present invention is to provide a wearable automatic charging device that can be easily worn on the body and can be worn on an arm or ankle of a body with a large amount of movement to obtain large momentum even in small movements, thereby efficiently producing electrical energy. have.

A wearable automatic charging device according to the present invention for achieving the above object, a wearable portion detachably mounted to the user's body; A guide tube in the form of a hollow tube installed in the wearing part; A movable magnet that is slidably installed in the hollow portion of the guide tube and moves along the inside of the hollow portion by movement of the body; A coil wound on the outside of the guide tube to generate an induced current by the movement of the moving magnet; A charger that is installed to be connected to the coil on the inside of the guide tube or the wearing part to charge electrical energy; A fixed repulsive magnet that is fixedly installed at one or both ends of the guide tube to generate repulsive force on the moving magnet and push the moving magnet in the opposite direction to the moving direction; And a connecting unit connecting the charger and the electric device to supply electric energy stored in the charger to an external or internal electric device.

According to the present invention, it is worn on the arm or ankle of a body with a large amount of movement, and thus a large amount of movement can be obtained even in a small movement. In particular, since the movement of the moving magnet is further increased by the fixed repulsive magnet installed on the guide tube, the electric energy is efficiently Can produce.

In addition, when the electric energy of the charger is supplied by incorporating an electric heater in the wearing part, it functions as a heating pad or a heating pad in winter to prevent frostbite or cold during external activities or work.
