Embodiments of the invention

In order to facilitate the understanding of those skilled in the art, the present invention is further described below in conjunction with the accompanying drawings, and is not intended to limit the scope of the present invention.

In daily life, smart wearable devices, for example, smart watches, smart watches will always be worn on the wrists of consumers. During the walking process, the wrists will swing continuously, which will generate kinetic energy. If it can be generated by using a device. The kinetic energy is converted into electrical energy and stored in the battery, which greatly improves the endurance.

The kinetic energy conversion module includes a chamber and a movable member;

Referring to Figure 1, an embodiment of the present invention provides a power generation device including: a kinetic energy conversion module S1, an alternating current AC-DC power conversion rectifier device S2, a buck-boost circuit device S3, a charging device S4, and an external charging device S5. Battery S6, and processor S7.

In one embodiment of the present invention, the kinetic energy conversion module S1 converts kinetic energy into electrical energy by means of induction of electricity. In this embodiment, the chamber is an insulated cylinder that encloses the vacuum, and the movable member is a permanent magnet. In the embodiment of the present invention, the permanent magnet is described by taking a permanent magnet as an example.

2A, 2B, and 2C are schematic structural views of a kinetic energy conversion module according to an embodiment of the present invention. The kinetic energy conversion module S1 includes an insulating cylinder S11, an inductor S12, a permanent magnet S13, and an outer protective casing S14.

In Fig. 2A, the insulating cylinder S11 has a circular cross section and a cross section perpendicular to the axial direction. The insulating cylinder S11 has a flat cross section of a circular ring, a flat cross section parallel to the axial direction of the insulating cylinder S11, and a plane which is bilaterally symmetrical with each other on both sides of the flat cross section.

2A is a schematic view showing a flat cross section of the insulating cylinder S11 as a circular ring. By setting the flat section of the insulating cylinder to a circular ring shape, when the power generating device of this shape is applied to a smart wristband or a smart watch, it is not necessary to occupy a very tight space in the middle of the smart wristband or the watch, and only use a wristband or a watch. The kinetic energy conversion device is placed in the space around the corner of the outer casing, and in view of the arrangement of the conversion device, the kinetic energy of the swinging arm of the human walking arm can be converted into electric energy to the utmost.

For a smart wearable device with a very small battery capacity, the improvement of the endurance provided by the power generating device provided by the embodiment of the present invention will be very obvious, and the user experience can be improved.

The number of permanent magnet magnets S13 may be one or more, for example, two permanent magnets of the same shape are provided.

The inductor S12 wound on the insulating cylinder S11 may be one or more. The inductor SS12 may be uniformly distributed on the S11, or may be a coil or a plurality of coils at any position of the insulating cylinder S11 as needed. In the case that the smart wearable device structure space allows, the plurality of kinetic energy conversion modules S1 may be repeatedly combined in parallel, and may be a combination of kinetic energy conversion modules S1 of any shape.

The shape of the permanent magnet magnet S13 is set to conform to the shape of the inner wall of the insulating cylinder S11, and a certain gap is left so that the permanent magnet magnet S13 can move inside the insulating cylinder S11.

The shape of the chamber is primarily considered in two factors:

One factor is that the shape of the chamber is set according to the shape of the smart wearable device, for example, for a smart bracelet or a watch, the flat section of the chamber is set to a ring shape, or a combination of a plurality of fan shapes; for virtual reality (Virtual Reality, VR) glasses, the flat section of the chamber is set to a rectangular shape, or a combination of a plurality of rectangles, that is, the chamber is cylindrical and can be placed in the temple portion; for the smart running shoes, the chamber is The flat section is set to a U shape, an arc conforming to the edge of the sole, or a semi-annular shape, thereby placing the power generating device at the upper. The shape of the chamber cooperates with the shape of the smart wearable device. In addition, the number of the chambers is plural, and is respectively disposed at any available position in the smart wearable device structure space. By arranging the chamber in a space in the smart wearable device that can be used for charging, by the above arrangement, the size of the charging device can be made small without occupying too much space of the smart wearable device;

Another factor is that the axial direction of the chamber is set to move with the movement of the wearable smart device with the human body, and the axial direction has the largest intersection with the direction of motion; such an arrangement can make the conversion of kinetic energy into electrical energy more efficient. Optionally, for the usage of the smart wearable device, analyze the motion trajectory of the smart wearable device during use, count the direction of the motion trajectory, and set the axial direction of the chamber according to the statistical result of the motion direction.

When the human body wears a smart device such as a wristband, the curve drawn by the arm swing is a semicircle. At this time, the permanent magnet magnet S13 moves in the vacuum insulation cylinder S11 as the human arm swings, and the insulation cylinder S11 is designed into a ring shape. The kinetic energy generated by the swing of the arm can be utilized to the utmost; the vacuum is to reduce the resistance of the permanent magnet when moving. The permanent magnet magnet S13 can generate an induced electromotive force when passing through the inductor S12 while moving. The permanent magnet magnet S13 is designed to have a ring shape corresponding to the shape of the insulating cylinder S11, and can generate a large induced electromotive force, and the permanent magnet S13 can optionally use a high magnetic energy product of a permanent magnet material. S14 is a housing protection device, which can be any material and shape that is advantageous for structural realization.

In the embodiment of the present invention, the flat cross section of the insulating cylinder is taken as an example. Further, the flat section of the insulating cylinder may have other shapes, for example, a rectangular shape, a sector shape, an elliptical ring shape, a Japanese shape, or the like.

The voltage of the AC-DC conversion rectified output may be higher than 5V or lower than 5V. This is completely determined by the conversion result of kinetic energy. In order to ensure a constant voltage output, the voltage boosting circuit device S3 is used to control the voltage.

In the embodiment of the present invention, the charging device S4 is configured to charge the battery S6 at the back end of the power supply converted by the AC-DC conversion rectifying device S2.

In the embodiment of the present invention, the processor S7 is configured to control the charging mode, control the charging device S4 or the external charging device S5 to charge the battery S6, and when the external charging device S5 is valid, perform the battery S6 through the external charging device S5. Charging, when the external charging device S5 is inactive, the battery S6 is charged by the charging device S4.

The movable member S1A3 is an object having a rough surface with a certain specific gravity, and is arranged to generate friction with S1A1, for example, a rough iron piece. When the movable member S1A3 and the cylinder S1A1 move relative to each other, the movable member S1A3 and the cylinder S1A1 The friction between them causes the frictional potential to be generated.

When a person wears the wearable device while walking, the arm swings, and the movable member S1A3 moves in the cylinder S1A1 as the human arm swings, generating friction, and then the friction point of the cylinder S1A1 generates a friction potential.

The shape of the movable member S1A3 is matched with the shape of the cylinder S1A1 as long as the movable member S1A3 is an adapted shape that can facilitate movement in the space of the cylinder S1A1.

The cylinder S1A1 has a circular cross section and a cross section perpendicular to the axial direction.
