In summary of the above technical features, the main effects of the footwear magnetic induction power generation warning device and method of the present invention will be apparent from the following embodiments.

The present invention is described in the first to fourth embodiments. The preferred embodiment of the present invention is a footwear magnetic induction power generation warning device, which is used in conjunction with a bicycle (A) two pedals (1), and includes:

a magnetic module (2) is disposed on one of the shafts (11) of the pedal (1), the shaft (11) is rotated relative to the pedal (1), the pedal (1) and the shaft ( 11) is provided with a bearing having a plurality of balls for assisting the relative rotation of the shaft (11) in the pedal (1) (this is a conventional technique, which is not shown in the drawings), the magnetic The module (2) includes a plurality of magnets (21), and the plurality of magnets (21) are arranged around the axis (11) magnetically spaced apart, and the magnetic module (2) generates a magnetic field (22).

a shoe body (3) that is stepped on the pedal (1), the shoe body (3) is provided with a power generation module (31) and a light-emitting element (32), and the light-emitting element (32) is electrically connected to the power generation The module (31) includes an induction coil (311), a power storage unit (312) and a rectifier (313). The capacitor (312) is a super capacitor.

Please refer to the fourth and fifth figures. In order to advance the bicycle (A), the two pedals (3) must be alternately stepped on the pedal (1) of the bicycle (A) to make the pedal ( 1) The rotational displacement is generated (the two sides are operated in the same way, so they are represented by one side in this figure).

The induction coil (311) of the shoe body (3) thus cuts the magnetic lines of the plurality of magnets (21) through the magnetic field (22) of the magnets (21), and because the axis (11) is opposite to the pedal (1) Rotating to advance the bicycle (A), so that the number of magnetic lines of the magnets (21) changes within the induction coil (311) and the magnets (21) move relative to the induction coil (311). In order to generate an induced current. It should be particularly noted that the present invention uses the principle of electromagnetic induction to generate electricity, which is a conventional technique and will not be described again.

The rectifier (313) rectifies the induced current into direct current, and then stores the same into the power storage unit (312), so that the light-emitting element (32) stably emits a warning light source to protect the safety of the bicycle rider during nighttime when the line of sight is poor. .

Referring to FIG. 6 again, the axis of the embodiment of the present invention is rotated relative to the pedal (the two sides are operated in the same manner, so one side is shown in the figure) to further explain the magnets ( 21) The relative relationship between the pedal (1) and the induction coil (311) of the shoe body (3).

Taking one of the magnets (21A) of the plurality of magnets (21) as an example, one of the magnets (21A) rotates with respect to the pedal (1) with the shaft (11) for the user. The bicycle body (3) is stepped on, and the rotation displacement is generated to drive the bicycle (A) to advance. In the embodiment, the initial position of the magnet (21A) is relatively close to the shoe body (3), so that the power generation is performed. The induction coil (311) of the module (31) passes through the magnetic field (22) to cut the magnetic lines of force of the magnet (21A).

The user stepped on the pedal (1) in the direction in which the bicycle (A) advances by the shoe body (3), and causes the shaft (11) to rotate the magnet (21A) to make the magnet (21A) The magnetic field (22) is away from the induction coil (311). After the pedal (1) is stepped on, the magnet (21A) returns to the initial position to pass the induction coil (311) again through the magnetic field (22), so the magnet (21A) and the induction coil (311) have relative motion during the stepping, and the number of magnetic lines in the induction coil (311) changes, thereby generating the induced current.

It can be seen from one of the above magnets (21A) that the plurality of magnets (21) rotate with respect to the pedal (1) with the axis (11), and after the pedal (1) is stepped on, the plurality of magnets (21) will be repeated. Passing/disturbing the magnetic field (22), the relative movement between the magnets (21) and the induction coil (311) during the stepping process is repeated, so that the number of magnetic lines in the induction coil (311) constantly changes. The induced current is continuously generated for the light-emitting element (32) to stably emit the warning light source.

The invention also provides a footwear magnetic induction power generation warning method, comprising the following steps:

A. A magnetic module (2) is mounted on at least one pedal (1) of the bicycle (A), and the magnetic module (2) generates a magnetic field (22).

B. The induction coil (311) is mounted on the shoe body (3).

C. The shoe body (3) is stepped on the pedal (1) to generate a rotational displacement, and the induction coil (311) is passed through the magnetic field (22) to generate an induced current.

D. Using the induced current, the light-emitting element (32) of the shoe body (3) emits a warning light source.
