[0034] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0035] It should be noted that all directional indications in the embodiments of the present application (such as up, down, left, right, front, back, etc.) are only used to explain the relative position relationship and movement status between the components in a certain specific posture. If the specific posture changes, the directional indication will also change accordingly.

[0036] It should also be noted that when an element is referred to as being "fixed to" or "disposed on" another element, it may be directly on the other element or there may be an intervening element. When an element is referred to as being "connected to" another element, it may be directly connected to the other element or indirectly connected to the other element through an intervening element.

[0037] In addition, the descriptions of "first", "second", etc. in this application are for descriptive purposes only and should not be understood as indicating or implying their relative importance or implicitly indicating the number of the technical features indicated. Therefore, the features defined as "first" or "second" may explicitly or implicitly include at least one of such features. In addition, the technical solutions between the various embodiments can be combined with each other, but this must be based on the fact that they can be implemented by ordinary technicians in this field. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by this application.

[0038] In some related technologies, the built-in batteries of wearable devices such as smart rings and smart bracelets mainly use two charging methods: wireless charging and wired magnetic charging. That is, charging is carried out by contact or proximity with a wireless charging base, and charging is carried out by connecting the magnetic charging interface to a charging device such as a charging stand.

[0039] However, when charging, the wearable device needs to be removed and connected to an external power source through a charging cable or charging box to continuously power the wearable device for charging and replenishing, and the user cannot use it during the charging process.

[0040] like Figure 1 As shown, therefore, the embodiment of the present application provides a wearable device 1, which can realize continuous power supply to the wearable device 1 without the need for an external power supply, is convenient to charge, and the wearable device 1 can continue to be used during the charging process.

[0041] like Figures 1 to 3As shown, the wearable device 1 provided in the embodiment of the present application includes a wearable body 10, an electromagnetic coil 20, a magnet 30 and an energy storage element 40. The wearable body 10 is used to be worn on the human hand. The electromagnetic coil 20 and the energy storage element 40 are both arranged in the wearable body 10. The electromagnetic coil 20 forms an induction channel 21. The magnet 30 is movably located in the induction channel 21. The magnet 30 is used to move relative to the electromagnetic coil 20 when the wearable body 10 follows the movement of the human hand to generate relative displacement; the electromagnetic coil 20 is electrically connected to the energy storage element 40; specifically, in this embodiment, the wearable device 1 can be a finger ring. The wearable device 1 is worn on the finger. When the finger moves (such as shaking left and right, swinging back and forth, or moving up and down), the magnet 30 in the finger ring will move relative to the finger ring under the action of inertia, so the magnet can cut the electromagnetic coil 20 to generate electromagnetic induction and thus generate current.

[0042] In the wearable device 1 of this embodiment, a wearable body 10 is provided for easy wear on a human hand. An electromagnetic coil 20 and a magnet 30 are provided, and the magnet 30 is movably located within an induction channel 21 formed by the electromagnetic coil 20. Utilizing the electromagnetic induction phenomenon, when the human hand moves in any direction, the wearable body 10 will follow the movement of the human hand. In this case, the magnet 30 is subjected to relative motion with the electromagnetic coil 20 due to inertia or gravity, resulting in relative displacement, thereby generating current. For example, when the human hand drives the wearable body 10 upward, the magnet 30, which is movably located within the induction channel 21, moves downward relative to the electromagnetic coil 20 under the action of gravity, and cuts the magnetic lines of force of the electromagnetic coil 20 magnetic field, generating current. At the same time, the electromagnetic coil 20 is electrically connected to the energy storage element 40, such as by a wire (not shown), so that the electromagnetic coil 20 and the energy storage element 40 form a closed circuit, so that the current generated by the relative displacement of the magnet 30 and the electromagnetic coil 20 is stored in the energy storage element 40.

[0043] In this way, the current generated by the relative movement between the magnet 30 and the electromagnetic coil 20 to cut the magnetic lines of force is converted into electrical energy and stored in the energy storage element 40. The wearable device 1 can be continuously powered without using an external power supply, so there is no need to carry charging cables or charging boxes and other equipment, charging is convenient, and the portability and practicality of the wearable device are improved. At the same time, during the charging process, there is no need to remove the wearable device 1 from the human hand, so that the wearable device 1 can continue to be worn and used during the charging process, which helps to extend the use time of the wearable device 1.

[0044] It should be understood that in some application scenarios, the wearable device 1 can establish communication with a terminal such as a mobile phone, and can interact with the terminal by touching the surface of the wearable device 1 to change the terminal interface, such as turning pages. In some embodiments, the wearable device 1 can be worn on one of the fingers of the human body. The finger wearing the wearable device 1 can drive the magnet 30 to move during movement, such as shaking the finger to drive the magnet 30 to move. In this case, the finger of the other hand can be used to touch the surface of the wearable device 1, so that the wearable device 1 can continue to be used during the charging process. Of course, in other embodiments of the present application, the wearable device 1 can be worn on the wrist of one arm of the human body. The wrist can drive the magnet 30 to move when moving. In this case, the finger of the other arm can also be used to touch the surface of the wearable device 1, so that the wearable device 1 can continue to be used during the charging process. It should be noted that the human palm or arm can move arbitrarily, driving the magnet 30 in the sensing channel 21 to move in any direction, such as when the finger or arm is swung downward or upward to swing the wearable body 10, the magnet 30 moves upward or downward.

[0045] like Figure 1 and Figure 2 As shown, in some embodiments, a first receiving space 12 and a second receiving space 13 are provided in the wearable body 10. The first receiving space 12 is used to accommodate the electromagnetic coil 20 and the magnet 30, and the second receiving space 13 is used to accommodate the energy storage element 40. The space in the wearable body 10 is reasonably divided, and the electromagnetic coil 20 and the magnet 30 are reasonably arranged in the first receiving space 12, and the energy storage element 40 is arranged in the second receiving space 13, so that the space in the wearable body 10 is reasonably used.

[0046] like Figure 1 and Figure 2 As shown, in some embodiments, the wearable body 10 is annular, and the annular wearable body is surrounded by a wearing hole 11, and the wearing hole 11 can be passed through by the human hand, so that the wearable body 10 can be worn on the human hand, such as worn on the human finger, wrist, etc. At the same time, the wearing hole 11 is formed by the wearable body 10, which can reduce the volume of the wearable body 10, which is conducive to the miniaturization design of the wearable device 1. In some embodiments, the wearable body 10 is an annular shell, and the shell has a protective function, which can protect the electromagnetic coil 20, magnet 30 and energy storage element 40 installed therein. In some embodiments, the first receiving space 12 and the second receiving space 13 are arranged along the axial direction of the wearing hole 11, and the arrangement is reasonable.

[0047] like Figure 1 and Figure 4As shown, in some embodiments, the inner circumference of the wearable body 10 is thickened along the radial direction of the wearing hole 11 to form a thickened portion 14, which can improve the structural stability of the wearable body 10. For example, when the wearable body 10 is an annular shell, the thickened portion 14 can be understood as a portion of the inner circumferential wall of the shell.

[0048] Combine Figure 2 In some embodiments, a partition (not shown) is provided within the wearable body 10 to separate the wearable body 10 into a first receiving space 12 and a second receiving space 13. In this embodiment, providing a partition to separate the wearable body 10 into the first receiving space 12 and the second receiving space 13 can improve the stability of the first receiving space 12 and the second receiving space 13.

[0049] In a specific embodiment of the present application, the wearable body 10 also includes a flexible circuit board (not shown), the energy storage element 40 is electrically connected to the flexible circuit board, and is placed together in the first receiving space 12; the electromagnetic coil 20 is placed in the second receiving space 13; in some other embodiments, the energy storage element 40 may also be electrically connected to the flexible circuit board, and are placed together in the second receiving space 13; the electromagnetic coil 20 may be placed in the first receiving space 12.

[0050] Combine Figure 1 and Figure 3 In some embodiments, the electromagnetic coil 20 has a first end (not shown) and a second end (not shown). The electromagnetic coil 20 is disposed around the inner wall of the wearing hole 11, and the first end and the second end are connected, so that the electromagnetic coil 20 encloses an induction channel 21; in the axial direction of the wearing hole 11, the orthographic projection of the induction channel 21 is annular. In this embodiment, the electromagnetic coil 20 encloses a ring-shaped induction channel 21, and the magnet 30 can move within the ring-shaped induction channel 21. When the wearable body 10 follows the movement of the human hand, the magnet 30 can move relative to the electromagnetic coil 20 within the ring-shaped induction channel 21, thereby increasing the range of motion of the magnet 30.

[0051] Combine Figure 2 In some embodiments, the wearable body 10 further includes a connecting portion (not shown), through which the electromagnetic coil 20 is electrically connected to the energy storage element 40. The connecting portion may be a wire or a flexible printed circuit (FPC), which is used to realize the electrical connection between the electromagnetic coil 20 and the energy storage element 40, so that the electromagnetic coil 20 and the energy storage element 40 form a closed loop, so as to transmit the current generated by the relative displacement of the magnet 30 and the electromagnetic coil 20 to the energy storage element 40.

[0052] Combine Figures 1 to 3In some application embodiments, when the wearable body 10 follows the human finger or wrist to perform movements such as up and down, forward and backward, and arm swinging, the magnet 30 and the electromagnetic coil 20 will cause relative movement, thereby generating current.

[0053] Combine Figures 1 to 3 In one application embodiment, when the wearable body 10 follows the human body's fingers or wrist to perform up and down, forward and backward, arm swinging and other movements, the magnet 30 moves downward in a clockwise direction under the action of gravity and cuts downwardly the magnetic lines of force of the electromagnetic coil 20's magnetic field. At the same time, the electromagnetic coil 20 can cut upwardly the magnetic lines of force of the magnetic field of the magnet 30, and the magnet 30 and the electromagnetic coil 20 produce relative displacement, thereby generating current between the magnet 30 and the electromagnetic coil 20. Since the electromagnetic coil 20, the connecting part and the energy storage element 40 form a closed loop, the connecting part is in a conductive state, and the connecting part can transmit the current generated between the magnet 30 and the electromagnetic coil 20 to the energy storage element 40.

[0054] Combine Figures 1 to 3 In another application embodiment, when the wearable body 10 follows the human body's fingers or wrist to perform up and down, forward and backward, arm swinging and other movements, the magnet 30 can move upward in a counterclockwise direction and cut the magnetic lines of force of the magnetic field of the electromagnetic coil 20 upward. At the same time, the electromagnetic coil 20 can cut the magnetic lines of force of the magnetic field of the magnet 30 downward, and the magnet 30 and the electromagnetic coil 20 produce relative displacement, thereby generating current between the magnet 30 and the electromagnetic coil 20. Since the electromagnetic coil 20, the connecting part and the energy storage element 40 form a closed loop, the connecting part is in a conductive state, and the connecting part can transmit the current generated between the magnet 30 and the electromagnetic coil 20 to the energy storage element 40.

[0055] Combine Figure 2 In some embodiments, the wearable device further includes a controlled switch 50 and a connection portion (not shown). The electromagnetic coil 20 is connected to the energy storage element 40 via the connection portion. The controlled switch 50 is disposed on the connection portion and is used to change the direction of the current. In this embodiment, the controlled switch 50 can control the on / off state of the connection portion and maintain the connection portion in a conductive state during relative motion between the magnet 30 and the electromagnetic coil 20. Exemplarily, the connection portion is a wire.

[0056] In this embodiment, relevant existing circuit technologies, such as a bridge rectifier circuit, can also be combined. With reference to the bridge connection method of the four diodes in the bridge rectifier circuit, a suitable type of controlled switch 50 can be selected so that the controlled switch 50 can realize current reversal when changing the on-off state. In this way, when the magnet 30 moves clockwise in the sensing channel 21 to generate a current in a first direction, and when the magnet 30 moves counterclockwise in the sensing channel 21 to generate a current in a second direction, the controlled switch 50 can change the current direction accordingly according to the direction of the current flow, so that the current generated by the clockwise movement of the magnet 30 and the current generated by the counterclockwise movement of the magnet 30 are both transmitted to the energy storage element 40 through the connection portion, thereby reducing energy loss.

[0057] Combine Figure 2 In some embodiments, the wearable device 1 further includes a circuit board (not shown), on which circuit modules required for the operation of the wearable device 1 may be integrated, an energy storage element 40 is disposed on the circuit board, and a microcontroller 60 is also disposed on the circuit board, and the energy storage element 40 is electrically connected to the microcontroller 60.

[0058] In this embodiment, the energy storage element 40 is installed on the circuit board, which can improve the installation stability of the energy storage element 40. A microcontroller 60 is provided on the circuit board. The microcontroller 60 can manage the storage and use of electrical energy. The microcontroller 60 can be an existing controller with data processing, storage and other functions.

[0059] Combine Figure 2 In some embodiments, the circuit board and microcontroller 60 are housed within the second receiving space 13. The microcontroller 60 can control the connection portion to transmit the current generated between the magnet 30 and the electromagnetic coil 20 to the energy storage element 40 for storage when the magnet 30 and the electromagnetic coil 20 move relative to each other. The microcontroller 60 can also control the energy storage element 40 to provide power to components such as the touch buttons in the wearable device 1. In some embodiments, a controlled switch 50 is housed within the second receiving space 13 and is electrically connected to the microcontroller 60, which can control the on and off of the controlled switch 50.

[0060] Combine Figure 1 and Figure 2In some embodiments, the circuit board includes a supporting plate body (not shown) provided in the second receiving space 13, the supporting plate body extends along the circumference of the wearing hole 11, and the energy storage element 40 is mounted on the supporting plate body to improve the stability of the energy storage element 40 installed in the wearable body 10. In some embodiments, the energy storage element 40 is welded to the supporting plate body. In other embodiments, a mounting groove (not shown) is formed on the supporting plate body, and the energy storage element 40 is fixed in the mounting groove. In some embodiments, a card slot (not shown) is formed on the energy storage element, and a buckle (not shown) is formed on the supporting plate body, and the energy storage element 40 is clamped to the supporting plate body by engaging the buckle with the card slot.

[0061] Combine Figure 2 and Figure 3 In some embodiments, the magnet 30 is a magnet. Preferably, the magnet 30 is a neodymium iron boron magnet, which has magnetism and can generate a magnetic field. It can also generate displacement by relative movement with the electromagnetic coil 20 in the sensing channel 21 when the wearable body 10 follows the movement of the human hand.

[0062] Combine Figure 2 and Figure 3 In some embodiments, the magnet 30 is columnar, such as a cylindrical magnet 30, and the magnetic lines of force are evenly distributed, so that when the magnet 30 and the electromagnetic coil 20 are relatively displaced, the electromagnetic coil 20 cuts the magnetic lines of force generated by the magnet 30.

[0063] Combine Figure 2 and Figure 3 In some embodiments, the volume of the magnet 30 is V1, the volume of the wearable body 10 is V2, and the volume of the sensing channel 21 is V3, wherein the ratio of V1 to V2 is 0.008 to 0.012, and the ratio of V3 to V2 is 0.1 to 0.2. In this embodiment, the volume ratio of the magnet 30 to the wearable body 10 is 0.008 to 0.012, preferably 0.01, and the volume ratio of the sensing channel 21 to the wearable body 10 is 0.1 to 0.2. When the wearable body 10 follows the movement of a person's finger or wrist, it can drive the magnet 30 to move in the sensing channel 21, so that the magnet 30 and the electromagnetic coil 20 are relatively displaced, thereby generating current.

[0064] Specifically, in this embodiment, by setting the magnet 30 to a cylindrical shape (with a good curvature for easy rolling) and setting the volume ratio of the magnet 30 to the wearable body 10, the cylindrical magnet 30 can better move in the annular space within the wearable body 10, and the magnet 30 can have good freedom of movement in the annular space, thereby generating a larger current. In combination with the energy storage element 40, the wearable body 10 can be provided with a longer battery life.

[0065] Combine Figure 2 In some embodiments, the wearable device 1 is a finger ring, the energy storage element 40 includes a capacitor, and the electromagnetic coil 20 is electrically connected to the capacitor. Specifically, the electromagnetic coil 20 can be electrically connected to the capacitor through a connecting portion. The capacitor is used to store the current generated by the relative displacement between the magnet 30 and the electromagnetic coil 20. The capacitor can have unidirectional conductivity. For example, when the wearable device 1 is fully charged, the capacitor provides power to other components in the wearable device 1, such as touch keys. During the charging process of the wearable device 1, the capacitor receives and stores the current transmitted from the connecting portion.

[0066] Combine Figure 2 In other embodiments, the wearable device 1 is a finger ring, the energy storage element 40 includes a battery, and the electromagnetic coil 20 is electrically connected to the battery. Specifically, the electromagnetic coil 20 can be electrically connected to the battery through a connecting portion. The battery is used to store the current generated by the relative displacement between the magnet 30 and the electromagnetic coil 20. The battery can have unidirectional conductivity. For example, when the wearable device 1 is fully charged, the battery provides power to other components in the wearable device 1, such as touch keys. During the charging process of the wearable device 1, the battery receives and stores the current transmitted from the connecting portion.
