Description

Generating apparatus of ferrite core type for mounting to the hub of a body of revolution}

The present invention relates to a ferrite core type self-generating device for hub mounting of a rotating body, and more specifically, to a center of a rotating object such as a wheel of a bicycle, a wheel of a motorcycle, a wheel of a cart, a wheel of a baby carriage, and the like. The present invention relates to a ferrite core type self-generating device for hub mounting of a rotating body, which maximizes the amount of power generated by improving the structure of the self-generating device so as to be suitable for the structure of the hub, and obtains an excellent luminous effect by the induced current obtained therefrom.

In general, a self-generator is a device that is mounted to a predetermined portion of a rotating object to generate an induction current, and consists of a combination of a magnet to form a magnetic field and a coil to generate an induction current under the influence of the magnetic field.

The self-generator is being changed in various ways according to the use, and one of them is mounted on a predetermined part of a wheel that is commonly equipped with a rotating body that rotates, that is, a bicycle, a motorcycle, a cart, etc. to obtain a predetermined amount of power generation. There is a self-generator whose structure is appropriately improved.

As described above, the vehicle is driven by a manpower or a power unit such as a motor. At this time, the wheel is rotated by such an external force, so that the kinetic energy of the wheel's rotational motion is transferred to the electric generator. When it is converted into energy to secure a predetermined amount of power generation, it is possible to achieve its purpose, such as to obtain a predetermined electrical effect without the hassle of having a separate power supply means such as a battery.

Of course, the electrical energy obtained through the self-generator is electrically connected to a light emitting device such as a beacon or a lighting lamp separately provided in the vehicle, thereby exhibiting a luminous effect for securing night vision or satisfying visual preferences. It can also be connected to a battery of devices to produce a variety of electrical effects.

On the other hand, the conventional self-generator structure used to obtain electrical energy by using the rotational force of the rotating body, such as a wheel, is a gating method of direct contact with the rotating wheel to obtain the rotational force to induce a relative rotational movement of the magnet and the coil Equipped with a power generation structure, or equipped with a self-generating device in the hub corresponding to the center of the rotating body has a hub-mounted power generation structure using the relative rotational movement of the hub and the fixed shaft penetrating the center of the hub.

However, the power generation structure of the conventional gripping method has a problem that it is very difficult to achieve the desired effect due to the wear caused by direct friction with the rotating body, difficulty in adjusting the friction interval, lack of power generation due to obstructing the rotational movement of the rotating body.

In addition, the power generation structure of the existing hub mounting method, which slightly improves the power generation structure of the gating method, has solved the problem according to the gating method, but the relative positioning of the coil and the magnet is not properly made to suit the mounting method. There was a problem that can not maximize the power generation.

In addition, the above-described self-generators do not have an organic coupling structure with all light emitting devices, so it is cumbersome to mount them on the hub of the rotating body, and they do not form a compact structure to satisfy the user's visual preferences. In addition, since a plurality of wires used to electrically connect the self-generator and the light emitting device are exposed to the outside, a partial breakage of the local part is caused, which requires frequent replacement.

The object of the present invention is to provide a structure of a self-powered device that can be installed in the rotating hub to obtain an induction current so that there is no obstacle in the rotational movement of the rotating body, the compact configuration is suitable for mounting to various structures of the rotating hub And easy electrical coupling with all electric devices, especially the ferrite core type for hub mounting of rotating body that can maximize the amount of power generation by optimizing the structure of magnet and coil and relative positioning between each other To provide a self-powered device.

It consists of a ferrite core 15 coupled to one side of the coil 13 wound on the ferrite core 15, the connector pin 14 is electrically connected to the coil 13 and protrudes to the other side of the substrate 10. .

In addition to the function of being fixed to the hub 2 of the rotating body, the substrate 12 also functions for electrical connection between the coil 13 and the connector pin 14. Ordinary printed circuit boards (Printed Circuit Board) and the like can be adopted.

The ferrite core 15, which can be referred to as a so-called crushed iron core, is located in the central empty space of the coil 13 wound and acts as a medium.
