It is to be understood that the specific embodiments described herein are merely illustrative of the application and are not limiting of the application. It should be further noted that, for the convenience of description, only some of the structures related to the present application are shown in the drawings, not all of the structures. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
Reference herein to "an embodiment" means that a particular feature, structure, or characteristic described in connection with the embodiment can be included in at least one embodiment of the application. The appearances of the phrase in various places in the specification are not necessarily all referring to the same embodiment, nor are separate or alternative embodiments mutually exclusive of other embodiments.

In daily sports and life, the human body consumes about 1.07 × 107J of energy in the forms of heat energy, kinetic energy and the like every day, and if the energy consumed by the human body is collected and converted, the new energy technology can be favorably supplemented. Compared with the method for collecting the heat energy of the human body by utilizing the thermoelectric material, the method for collecting the mechanical energy during the motion of the human body has the characteristics of high energy density, high conversion efficiency, simple collection system and the like.
Existing energy harvesting devices typically have a relatively large weight that interferes with the wearer's motion during use and increases the extra physical exertion on the wearer, especially when the energy harvesting device is placed on the end of the transmitting limb, the increase in energy expenditure is more pronounced; most of the existing energy collecting devices can not be organically combined with the wearing clothes of the wearing user, and need to be individually customized, so that the cost is high, and the existing energy collecting devices can not be popularized and used in a large range; further, some energy harvesting devices may be limited to certain situations and activities during use, such as some energy harvesting devices may only work when walking on level ground, and may not work properly if the terrain of the activity changes (e.g., walking up or down stairs, climbing a slope) or the mode of the activity changes (e.g., walking quickly, running). Based on this, in order to solve the above problems, the present inventors propose the following embodiments:
referring to fig. 1, fig. 1 is a schematic structural diagram of an embodiment of a power generation device provided in the present application, and as shown in the drawing, a power generation device 10 includes a connecting member 11, a power generation assembly 12 and a housing assembly 13, where the connecting member 11 may be connected to the power generation assembly 12 or connected to the housing assembly 13, in this embodiment, the housing assembly 13 is formed with an accommodating cavity, and the power generation assembly 12 is disposed in the accommodating cavity of the housing assembly 13, so that the connecting member 11 may be directly connected to the housing assembly 13; the connecting member 11 is detachably connected to a human body, a portion of the connecting member is fixedly connected to the housing assembly 13, another portion of the connecting member is connected to the human body and is used for fixing the power generating device 10 to the human body, and the housing assembly 13 is used for protecting the whole power generating assembly 12 and preventing the power generating assembly 12 from directly contacting with an external environment.
The power generation assembly 12 is configured to generate an induced current according to a movement posture of a human body, so as to supply power to an external device, where the external device generally includes a wearable electronic device, such as a watch, an intelligent bracelet, and the like, and may further include an electric storage device, and some internal devices included in the power generation apparatus 10 itself, such as a sensor, and the like, for implementing other functions.
Referring to fig. 2, fig. 2 is an exploded schematic view of an embodiment of the power generation apparatus provided in the present application, as shown in fig. 1 and fig. 2, the power generation assembly 12 includes a guide tube 121, a coil 122 and a magnet 123, the coil 122 is sleeved outside the guide tube 121, and the magnet 123 is disposed in the guide tube 121; the conduit 121 and the magnet 123 may be cylindrical structures, the conduit 121 is a hollow structure with a certain thickness, and the magnet 123 is a solid structure, in this embodiment, the radial dimension of the hollow portion of the conduit 121 is greater than the radial dimension of the magnet 123, so that the magnet 123 can be accommodated in the conduit 121 and move in the conduit 121.
Optionally, the coil 122 is sleeved outside the guide tube 121, specifically, wound in the axial direction of the guide tube 121, and the coil 122 is sleeved in the middle of the guide tube 121, that is, in the middle position, so that when the magnet 123 moves in the guide tube 121, the coil 122 can completely cut the magnetic induction line of the magnet 123, thereby generating an induced current of a sufficient magnitude. Wherein the axial length of the coil 122 is less than the axial length of the catheter 121, in the present embodiment, the axial length of the coil 122 may be about 1/3-1/4 of the axial length of the catheter 121, for example 1/4 of the axial length of the catheter 121. It is understood that the axial length of the coil 122 is related to the number of turns of the coil 122 and the material properties, and is not particularly limited herein.
Optionally, the axial length of the magnet 123 is less than the axial length of the catheter 121, and in this embodiment, the axial length of the magnet 123 may be about 1/3 of the axial length of the catheter 121, so that when the magnet 123 moves in the catheter 121, the coil 122 can completely cut the magnetic induction line of the magnet 123, thereby generating an induced current of sufficient magnitude.
In an application scenario, when a human body is in motion, the magnet 123 is influenced by a motion state of the human body, and slides in an axial direction of the catheter 121 under the action of inertia and gravity, because the coil 122 and the magnet 123 are respectively arranged at the outer side and the inner side of the catheter 121, when the magnet 123 slides to a corresponding position of the coil 122 in the catheter 121 and further passes through the corresponding position, relative movement occurs between the coil 122 and the magnet 123, which is equivalent to that the magnet 123 cuts the coil 122, and an induced current can be generated in the coil 122 according to faraday's law of electromagnetic induction, so that the subsequent practical application can be realized. The corresponding position of the coil 122 refers to a relative position between the magnet 123 and the coil 122 when the coil 122 can cut the magnetic induction line of the magnet 123. The size of the induced current generated by the electromagnetic induction is related to factors such as cutting speed, the number of turns of the coil, magnetic induction intensity and the like, and is in positive correlation.
In this embodiment, the power generation assembly 12 further includes a conversion circuit 124, and the conversion circuit 124 is connected to the coil 122, and may be connected to the coil 122 through a wire. Since the induced current generated by the coil 122 cutting the magnetic induction wire of the magnet 123 is an alternating current, the conversion circuit 124 is configured to convert the alternating current generated by the coil 122 into a direct current. It can be understood that since the internal circuitry of most external electronic devices generally requires a relatively stable dc power to operate, it is generally necessary to convert the induced current to convert the relatively low voltage ac power to a unidirectional pulsed and relatively high voltage dc power. The bridge rectifier circuit can be used for converting alternating current and direct current.
Further, the power generation assembly 12 further includes a voltage stabilizing circuit 125, and it can be understood that although the ac power generated in the electromagnetic induction phenomenon is converted by the converting circuit 124, the converted dc power still lacks a certain stability, and cannot provide a relatively stable voltage for an external device or its own electric device, so that a voltage stabilizing circuit 125 is usually connected to the output end of the converting circuit 124, and the voltage stabilizing circuit 125 is connected to the converting circuit 124 through a wire for performing a voltage stabilizing operation on the dc power output by the converting circuit 124 to output a stabilized current, so as to prevent voltage fluctuation, thereby avoiding device abnormality or failure at the output end.
The power generation device 10 in this embodiment does not need an additional motion conversion mechanism, so the overall mass of the whole device is light, the normal motion gait of the wearing user is not interfered, the extra physical consumption of the wearing user is not increased, and the user experience is improved.
By the device, on one hand, induced current can be generated according to the movement posture of the human body so as to convert the kinetic energy of the movement of the human body into electric energy, thereby realizing the effective conversion of energy; on the other hand, the power generation device 10 can be detachably connected with the human body by the connecting piece 11, and can be combined with each part of the human body according to different motion environments, so that certain compatibility is achieved.

Further, the tubular housing 131 is a cylindrical hollow structure having a certain thickness, and the radial dimension of the hollow portion of the tubular housing 131 is larger than the radial dimension of the coil 122 in the power generation module 12, so that the entire power generation module 12 can be accommodated in the housing module 13. Moreover, the radial dimension of the hollow portion of the tubular casing 131 is equal to the maximum radial dimension of the protrusions of the first cover 132 and the second cover 133, so that the two covers can seal the tubular casing 131 and protect the power generation module 12 housed in the cavity of the casing module 13.
