Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a non-contact type power generator for a bicycle using a magnet fastener,

The present invention relates to a non-contact type electric power generating apparatus for a bicycle, and more particularly, to a non-contact type electric power generating apparatus for a bicycle, To a non-contact type power generator for a bicycle, in which a current is induced in a coil winding wound around a magnet.

A bicycle generator is a device that converts the kinetic energy of a bicycle wheel into electric energy and is used to supply electric power to headlights or rear lights. These bicycle generators can be distinguished between contact type and non-contact type according to the principle of power generation. The contact type bicycle generator is a method of obtaining electric energy by rotating the roller through friction with the wheel of the bicycle. The efficiency is low due to the braking effect of the bicycle wheel due to friction, and the foreign matter (for example, Clay, etc.), there is a problem that noise is generated.

Unlike contact-type bicycle generators, contactless bicycle generators use eddy currents generated between the rim of the bicycle and the permanent magnets without using the wheel contact of the bicycle. More specifically, the non-contact bicycle generator may be composed of a plurality of magnets arranged adjacent to the rim of the bicycle and having N poles and S poles arranged at an intersection, and a coil winding wound along the outer surface of the magnet. Here, a magnetic field generated by a magnet is transmitted through a rim to generate an eddy current having opposite directions to the rim (Faraday's law), and a magnetic field in the same direction as the magnet is generated by this eddy current. Thereby, as the wheel of the bicycle rotates, the magnet rotates about the rotation axis, and a current can be induced in the coil winding due to the magnetic flux change of the coil winding wound around the magnet. Accordingly, the non-contact bicycle generator can convert the kinetic energy of the bicycle wheel into electric energy.

Meanwhile, the magnitude of the electric energy generated by the non-contact type bicycle generator is determined according to the capacity of the magnet of the rotor. In the conventional non-contact type bicycle generator, since a small capacity magnet is used to correspond to the length of the rim of the bicycle, The magnitude of the current induced in the current source is also inevitably small. Accordingly, the conventional non-contact type bicycle generator is used only as a blinker because it has a very low brightness to be used as illumination for securing a field of view at night.

In addition, when the capacity of the magnet is increased to have a size larger than the length of the bicycle rim in order to obtain a higher current, sufficient torque can not be provided to the magnet. Accordingly, there is a problem that electric currents generated at the time of initial driving of the bicycle or at low speed running are very small, so that electric energy necessary for securing the visual field can not be obtained.

The present invention relates to a magnet module having a magnet fastening member bound to a bicycle wheel, a magnet having an NS pole and an SN pole intersecting with each other along a rotation axis, and a coil winding wound around the magnet, The induction current is generated in the coil winding of the magnet module as the magnet of the magnet module rotates about the rotation axis by the magnetic action of the rim of the bicycle wheel and the magnet fastener, Contact type power generation device capable of obtaining a high current and electric energy by overcoming the above-mentioned problems and ensuring a bright field of view when the bicycle is driven at a low speed at night.

The objects of the present invention are not limited to the above-mentioned objects, and other objects and advantages of the present invention which are not mentioned can be understood by the following description and more clearly understood by the embodiments of the present invention. It will also be readily apparent that the objects and advantages of the invention may be realized and attained by means of the instrumentalities and combinations particularly pointed out in the appended claims.

To achieve these and other advantages and in accordance with the purpose of the present invention, as embodied and broadly described herein, there is provided a bicycle comprising: a magnet fastener having a bolt formed with a coupling groove into which a spoke of a bicycle wheel is inserted, a nut screwed with the bolt, and a first magnet coupled to the bolt or the nut; NS poles and SN poles intersecting each other, a second magnet configured to be able to magnetically act on the rim of the bicycle wheel and the magnet fastener, and a coil winding wound along the transverse plane of the second magnet, And a power generating module coupled to a mounting groove formed concavely on at least one side of both sides of the bicycle fork, wherein the attraction force acting between the second magnet and the rim when the wheel of the bicycle rotates, As the second magnet rotates about the rotation axis due to the repulsive force acting between the second magnets, Also it characterized in that the current is generated.

According to the present invention as described above, there are provided a magnet fastening member coupled to a bicycle wheel, a magnet having NS and SN poles interdigitated along the rotation axis, and a coil winding wound around the magnet, The induction current is generated in the coil winding of the magnet module as the magnet of the magnet module rotates about the rotation axis by the magnetic action of the rim of the bicycle wheel and the magnet fastener, It is possible to obtain high current and electric energy by overcoming the limitation of the current generation amount of the device and to secure a bright field of view when the bicycle runs at low speed at night.

1, a magnet fastener 110 of a non-contact type power generator using a magnet fastener of the present invention is bound to a spoke 20 of a bicycle wheel, and the power generation module 100 is connected to a fork 10 of a bicycle, Is mounted on a mounting groove (11) formed on at least one surface of the bicycle wheel of the vehicle.

The power generation module 100 includes a magnet having a shape capable of rotating along a rotation axis and a coil winding wound around a magnet. Specifically, the magnet of the power generation module 100 may be arranged so that the N-S pole and the S-N pole intersect with each other and magnetically act on the rim 30 and the magnet fastener 110 of the bicycle wheel. For example, the magnets of the power generation module 100 may be arranged such that the magnets having the polarities of the NS poles and the magnets having the SN poles cross each other about the rotation axis, or the poles of the NS poles and the SN poles They may be made to cross each other. The magnet of the power generation module 100 may be manufactured to have a size corresponding to the distance from the rim 30 of the bicycle wheel to the position where the magnet fastener 110 is engaged. Also, the coil winding is wound along the cross-section of the magnet of the power generation module 100, and an induction current can be generated in the coil winding as the power generation module 100 rotates around the rotation axis.

In the embodiment of the present invention, the power generation module 100 is characterized in that the bicycle fork 10 is coupled to the mounting groove 11 formed on at least one side of the surfaces facing the bicycle wheel. According to the present invention, since the mounting groove 11 is formed concavely in the bicycle fork 10 and the power generation module 100 is coupled to the inside of the mounting groove 11, It is possible to prevent breakage due to an external impact. In this case, the electric power generating module 100 and the lighting unit 100 are installed in the mounting groove 11 to which the electric power generating module 100 is coupled, An insertion groove into which a wire for connecting a wire can be inserted. Therefore, electric wires connecting the power generation module 100 and the lighting can be connected through the inside of the frame without being exposed to the outside of the bicycle.

Preferably, two power modules are installed on the bicycle fork according to the embodiment of the present invention. In this case, the first mounting groove and the second mounting groove are formed on both sides of the bicycle fork 10, 2 mounting groove, the first power generation module can be coupled to the first mounting groove, and the second power generation module can be coupled to the second mounting groove.

FIG. 2 is a view for explaining the operation principle of a non-contact type power generator for a bicycle using a magnet fastener according to an embodiment of the present invention. FIG. 3 is a view schematically showing a magnet of a magnet module according to an embodiment of the present invention to be.

2, the non-contact type power generator for a bicycle using the magnet fastener of the present invention includes a power module 100 and a magnet fastener 110 bound to a spoke 20 of a bicycle, May be arranged to be able to magnetically act on the rim 30 of the bicycle wheel and the magnet fastener 110.

More specifically, a bearing 106 for supporting the magnet 102 and a magnet 102 for supporting the magnet 102 such that the magnet 102, the magnet 102 of the power generation module 100 of the present invention can rotate about the rotation axis 104, And a housing 108 enclosing the magnet 102 and accommodating the magnet 102 therein. 3, the magnets 102 are arranged such that the magnets having the polarities of the NS poles and the magnets having the poles of the SN poles cross each other with respect to the rotation axis as shown in FIG. 3, or the poles of the NS poles and the SN poles And polarities cross each other. Preferably, the magnet 102 can be made in the form of a cylinder. Also, the magnet 102 may be an even number of magnets having polarities of N-S and S-N poles, or one magnet may be arranged so as to cross the poles of the N-S poles and the S-N poles. 2, a coil winding 109 is wound on the outer surface of the housing 108 along the cross section of the magnet 102 such that the magnet 102 is rotated about the rotational axis, The magnetic flux passing through the coil 109 can be changed and an induced current can be generated in the coil winding 109.

The magnet fastener 110 functions to fix the magnet to the spoke 20 of the bicycle using bolts and nuts. 4 is a view schematically showing a coupling relationship of a magnet fastener according to an embodiment of the present invention. Referring to FIG. 4, the magnet fastener 110 includes a bolt 112 having an engaging groove for inserting a spoke 20 of a bicycle wheel, a bolt 112 having a spoke 20 inserted into a coupling groove of the bolt 112, And a magnet 116 coupled to one side of the bolt 112 or the nut 114. [ One or more magnet fasteners 110 may be fastened to the spokes 20 of the bicycle and the magnet fasteners 110 may be fastened or partially fastened on each bicycle spoke. For example, the magnet fasteners 110 may be bound together by two spokes, or they may be bound together with different spacings of spokes.

The power generating module 100 and the magnet fastening unit 110 are configured such that when the wheel of the bicycle rotates, the power generating module 100 is rotated by the magnetic action between the magnet of the power generation module 100 and the rim 30 of the bicycle wheel. 100 is rotated in the direction in which the wheel rotates about the rotation axis. As described above, since the magnets of the power generation module 100 are disposed such that the NS poles and the SN poles cross each other, when the magnets rotate with respect to the rotation axis and have the same polarity as the magnets of the magnet fastener 110, A repulsive force acts between the magnet of the module 100 and the magnet of the magnet fastener, and the rotation of the power generation module 100 can be further accelerated.

 Specifically, the magnets of the power generation module 100 are arranged such that the NS poles and the SN poles are alternately arranged around the rotation axis. The magnetic field generated by the magnets of the power generation module 100, which is closest to the rim 30 of the bicycle, 30), and an eddy current having opposite directions to each other is generated, and a magnetic field due to each eddy current is generated again. On the other hand, in the magnetic field generated by the eddy current, the front magnetic field pulls the magnet of the power generation module 100 and the rear magnetic field pushes the magnet of the power generation module 100, The magnet of the power generation module 100 can rotate in the tangential direction of the direction in which the wheel of the bicycle rotates. Therefore, an induction current according to the electromagnetic induction law can be generated in the coil winding surrounding the magnet of the power generation module 100.

In a case where the magnets of the magnet fastener 110 are coupled so as to be N poles in a direction opposite to the power generation module 100, for example, when the wheels of the bicycle rotate, the magnets of the power generation module 100 are rotated in the rim 30) and rotates about the rotation axis. Since the magnets of the power generation module 100 are arranged so that the NS poles and the SN poles cross each other, the magnets of the power generation module 100 can be magnetized by the polarity (N pole) A repulsive force acts between the magnet of the power generation module 100 and the magnet fastener 110 so that a rotation acceleration force can be applied to the magnet of the power generation module 100 when the polarity (N pole) of the sphere 110 coincides with each other. In contrast, even when the magnets of the magnet fastener 110 are coupled to the S pole in the direction opposite to the power generation module 100, the polarity of the magnets of the power generation module 100 A repulsive force acts between the magnet of the power generation module 100 and the magnet fastener 110 so that the rotation acceleration of the magnet of the power generation module 100 Can be provided.

In the case of the conventional non-contact type power generation apparatus, since the induction current is generated only by the magnetic action between the rim of the bicycle and the power generation module, when the size of the magnet inserted into the power generation module is made to correspond to the length of the rim of the bicycle, There is a problem that the magnitude of the current induced in the coil winding is very small and the magnitude of the magnet can not be sufficiently provided by the magnetic action of the magnet and the rim when the capacity of the magnet is increased beyond the rim length.

According to the present invention, since the magnet of the magnet module rotates about the rotation axis by the magnetic action of the rim of the bicycle wheel and the magnet fastener, the induction current is generated in the coil winding of the magnet module, It is possible to obtain high current and electric energy by overcoming the limitation of the current generation amount and to secure a bright field of view when the bicycle runs at low speed at night.

On the other hand, generally, the rim 30 of the bicycle wheel is made of a metal having a very low magnetic susceptibility such as aluminum. Therefore, the magnetic action between the magnet of the power generation module 100 and the rim 30 of the bicycle wheel may be weak.

In the preferred embodiment of the present invention, the non-contact type power generator for bicycle using the magnet fastener of the present invention may further include a rim tape 40 attached to the rim 30 of the bicycle wheel. FIG. 5A is a view for explaining an embodiment in which a rubber magnet is attached to a rim of a bicycle wheel in the embodiment of FIG. 1, and FIG. 5B is a view for explaining a bicycle wheel according to the embodiment of FIG.

5A and 5B, when the rim tape 40 manufactured to have magnetism is attached to the rim 30 of the bicycle wheel, the magnetic force between the rim 30 of the bicycle wheel and the magnet of the power generation module 100 Can be strengthened. Here, the rim tape 40 attached to the rim 30 of the bicycle wheel may be a rubber magnet.

Further, in addition to the above-described power generation module 100 and the magnet coupling 110, the non-contact type power generation device for a bicycle using the magnet fastener of the present invention includes a battery for storing electric energy generated by the power generation module, An illumination unit for irradiating light, and a control unit for controlling them.

6 is a configuration diagram of a non-contact type power generator for a bicycle using a magnet fastener according to another embodiment of the present invention. Referring to FIG. 6, the non-contact type power generator for bicycle using the magnet fastener of the present invention is connected to the power generation module 502 and the power generation module 502 as described above to store the induced current generated in the power generation module 502 A lighting unit 506 for generating light as the induction current is applied to the battery 504 and an induction current generated by the power generation module 502 to be supplied to the battery 504 and to be supplied to the lighting unit 506 And a control unit 508 for controlling the operation of the apparatus.

The battery 504 refers to a secondary battery that can be used while repeating charging and discharging as electric energy is supplied, and may include, for example, a lithium polymer battery, a lithium ion battery, and the like. The illumination unit 506 may be an element or an apparatus that emits light when an electric current is supplied, and may include an LED or the like. In this way, it is possible to store electric energy in the battery 504 through the electric wire connected to the coil winding of the power generation module 502, and to supply the electric energy stored in the battery 504 if necessary.

The control unit 508 is connected to the power generation module 502, the battery 504 and the illumination unit 506 to charge the battery 504 using the current generated by the power generation module 502, And supplies the generated current and the current generated by the power generation module 502 to the illumination unit 506.

Specifically, the intensity of the light generated in the illumination unit 506 is proportional to the magnitude of the current generated in the power generation module 502. For example, when the bicycle travels at a low speed and the rotation speed of the bicycle wheel is low, since the magnitude of the current generated by the power generation module 502 is small, the intensity of the light is weak and the speed of the bicycle increases. The magnitude of the current generated in the power generation module 502 is sufficient to drive the bicycle at night.

The control unit 508 of the present invention controls a charging mode in which the induction current generated by the power generation module 502 is supplied to the battery 504 and the illumination unit 506 according to the magnitude of the current generated in the power generation module 502, When the induced current generated by the battery 502 is insufficient, the generated induction current and the current stored in the battery 504 may be supplied to the illumination unit 506. More specifically, the controller 508 compares the magnitude of the induced current with a predetermined reference current value. When the induced current is greater than the reference current value, the controller 508 operates in a charging mode. The battery 504 can be charged and the remaining current can be supplied to the illumination unit 506. The control unit 508 compares the magnitude of the induced current with a predetermined reference current value and operates in a discharge mode when the induced current is smaller than the reference current value. The control unit 508 generates the current stored in the battery 504, And supplies the generated current to the illumination unit 506. [

 FIG. 7A is a view for explaining the operation in the charge mode of the controller according to the embodiment of FIG. 6, and FIG. 7B is a view for explaining the operation in the discharge mode of the controller according to the embodiment of FIG.

7A, when the controller 508 operates in the charging mode, the controller 508 supplies part of the induced current generated by the power generation module 502 to the battery 504 to charge the battery 504 And supplies the remaining current to the illumination unit 506 at the same time. 7B, when the control unit 508 operates in the discharge mode, the control unit 508 supplies the electric current generated by the power generation module 502 and the electric energy of the battery 504 to the illumination unit 506 .

While the present invention has been described in connection with what is presently considered to be practical exemplary embodiments, it is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, But the present invention is not limited thereto.
