Description

Power generation module and wearable electronic device using the same

The present invention relates to a power generation module, and more particularly to a power generation module that generates current using a magnetic roller to roll and a wearable electronic device using the same.

With the advancement of technology, there are more and more types of portable electronic devices used in people's daily life. However, electronic devices on the market usually need to be replaced by batteries, charging cables, or mobile power sources to supply power to the devices. When there is no such related equipment, the supply of power becomes quite difficult. It can be seen that the demand for electric power is correspondingly more and more instantaneous, and thus the demand for charging devices is also increasing.

Generators are widely used in various industries. With the promotion of less battery movement, the design of miniaturized high-efficiency generators has become an important issue. Such micro-power generation devices can be installed on portable devices such as pockets, soles or uppers, glasses, watches, etc., and can also be used as emergency power, such as lighting or power supplies for radios and communications. Therefore, in addition to using the pre-charged mobile power source as the charging device, the aforementioned portable electronic device is also a future trend using the aforementioned small-sized, portable generator. However, although small power generators can be used as power sources for portable electronic products, how to generate sufficient power in a limited space and at a reasonable cost These conditions have become important factors for the large-scale portable power generation device to be widely promoted.

At present, the electromagnetic generator is mainly used in the conventional portable generator, and the driving mode of the electromagnetic generator can be divided into a continuous rotation type, a swing type, and a reciprocating type according to the motion type of the mover. . There are few reciprocating designs, but the most direct type of power drive in many cases is linear reciprocating motion. If the mechanism is turned into a rotary motion through the mechanism, the system efficiency will be ineffective.

However, the existing small reciprocating power generating device uses a spring-fixed magnet, and then uses a human power to shake the pipe body so that the magnet in the pipe body can have a magnetic field transition and generate a current. That is, a larger action is required to cause the magnet to move to cause a change in the magnetic flux, and a small action is less likely to generate sufficient power for the load to be used, which is quite laborious and inconvenient to use. In addition, the existing reciprocating generators are large in size and are not suitable for the demands of today's portable electronic devices.

In view of the above, an object of the present invention is to provide a power generation module including a guide member, a coil, and a magnetic roller body. Wherein the guiding member has an outer wall and an inner cavity, and the inner cavity has an extending direction. The coil is disposed around the outer wall of the guiding member, and the magnetic roller is disposed in the inner cavity of the guiding member and can reciprocately roll along the extending direction of the inner cavity. When the magnetic roller rolls back and forth in the inner cavity along the extending direction of the inner cavity, the magnetic flux density of the coil changes to generate a current.

According to an embodiment of the present invention, in the power module of the present invention, a cross-sectional shape of the inner cavity of the guiding member may be circular or rectangular.

According to an embodiment of the invention, the power module can be a spherical magnet.

According to an embodiment of the invention, the power module can be a disk magnet.

According to an embodiment of the present invention, a power generation module may further include a current output connector, and the current output connector is connected to the coil to output a current.

The power generation module according to an embodiment of the invention further includes a current storage unit, and the current storage unit is connected to the current output connector to store the current.

The power generation module according to an embodiment of the invention further includes a rectifying unit, and the rectifying unit is respectively connected to the current output connector and the current storage unit. Preferably, the rectifying unit is a rectifying diode.

According to an embodiment of the present invention, in the power generating module, the coil may be formed by surrounding at least one copper wire around the outer wall of the guiding member.

Another object of the present invention is to provide a wearable electronic device, and the wearable electronic device includes the power generation module.

Thereby, the present invention rolls the roller body around the guide member around which the coil is wound to achieve a change in the magnetic flux density, thereby generating a current. Since the roller is more susceptible to small movements, it is not necessary to supply an external force. As long as the wearing part moves, the roller will roll in the guide to generate electric current due to gravity, and can be widely used in wearable electronic devices. .

The Summary of the Invention is intended to provide a simplified summary of the present disclosure in order to provide a basic understanding of the disclosure. This summary is not an extensive overview of the disclosure, and is not intended to Important/critical elements of the embodiments or define the scope of the invention.
