[0035] Figure 1 is a three-dimensional schematic diagram of a charging device according to an exemplary embodiment. Figure 2 FIG. 1 is a side cross-sectional view of a charging device according to an exemplary embodiment. Figure 1 and Figure 2 As shown, the charging device includes: a magnetic component 100, an energy storage component 200 and a magneto-electric conversion component 300.

[0036] like Figure 1 As shown, the magnetic assembly 100 includes a housing 110. The housing 110 includes a side wall 111 and a bottom wall 112 connected to the side wall 111. Accordingly, the side wall 111 and the bottom wall 112 enclose a mounting cavity. Optionally, the housing 110 includes four side walls 111, and the four side walls 111 are arranged opposite to each other.

[0037] The magnetic assembly 100 also includes a magnet 120 disposed on the housing 110. The magnet 120 is disposed in the mounting cavity. Specifically, the magnet 120 includes a first magnet 121 and a second magnet 122 with opposite polarities. The first magnet 121 and the second magnet 122 are disposed on two opposite side walls 111. In this way, the magnetic field of the magnet 120 is distributed in the mounting cavity of the housing 110.

[0038] Optionally, the magnet 120 is a permanent magnet, which is fixed on the housing 110 by adhesive or fasteners.

[0039] The energy storage device 200 is used to charge an external electronic device. Optionally, the energy storage device 200 has a charging interface, which is connected to the charging interface of the external electronic device to charge the external electronic device. Optionally, the energy storage device 200 has a wireless charging transmitting end (e.g., a charging transmitting coil) for charging an electronic device having a wireless charging receiving end (e.g., a charging receiving coil).

[0040] Furthermore, the energy storage element 200 is movably connected to the magnetic component 100. Figure 1 , Figure 2 As shown, the charging device further includes an elastic member 400 connecting the energy storage member 210 and the housing 110. The elastic member 400 can be extended and retracted along the direction of cutting the magnetic flux lines of the magnetic field of the magnetic assembly 100.

[0041] For example, one end of the elastic member 400 is connected to the bottom wall 112 of the housing 110, and the other end of the elastic member 400 is connected to the energy storage member 210. At this time, the elastic member 400 stretches or contracts to drive the energy storage member 200 to move toward or away from the bottom wall 112.

[0042] Optionally, the charging device includes at least one elastic member 400. When the charging device includes multiple elastic members 400, the connections between the multiple elastic members 400 and the bottom wall 112 are evenly distributed on the bottom wall 112. For example, the charging device includes four elastic members 400, and the four elastic members 400 are respectively arranged at four corners of the bottom wall 112. In this way, the stable support of the elastic member 400 for the energy storage member 200 is optimized.

[0043] In addition, the size of the energy storage component 200 satisfies that the energy storage component 200 can move relative to the bottom wall 111 in the installation cavity of the housing 110. In this way, the volume of the entire charging device is reduced, making the charging device easy to carry. In addition, the energy storage component 200 can be placed in the installation cavity, and the housing 110 plays a role in protecting the energy storage component 200.

[0044] The electromagnetic conversion assembly 300 is disposed on the energy storage component 200. The electromagnetic conversion assembly 300 is relatively fixed to the energy storage component 200. At this time, the electromagnetic conversion assembly 300 can move with the energy storage component 200 relative to the magnetic component 100. In addition, during the movement of the electromagnetic conversion assembly 300 relative to the magnetic component 100, the electromagnetic conversion assembly 300 generates electrical energy based on the magnetic field of the magnetic component 100.

[0045] Optionally, the electromagnetic conversion assembly 300 includes a coil 310 wound on the energy storage member 200. The axial direction of the coil 310 faces the magnet 120. In this way, when the electromagnetic conversion assembly 300 moves with the energy storage member 200 relative to the magnetic assembly 100, the coil 310 can cut the magnetic flux of the magnetic field of the magnet 120, thereby causing a change in the magnetic flux passing through the coil. Based on the change in the magnetic flux passing through the coil, the coil 310 generates an induced current.

[0046] In addition, the electromagnetic conversion assembly 300 further includes a converter 320 electrically connected to the coil 310 and the energy storage component 200. The converter 320 is used to output the induced current generated by the coil 310 cutting the magnetic flux lines to the energy storage component 200 for storage. The current generated by the coil 310 cutting the magnetic flux lines of the magnet 120 is converted into a current adapted to the energy storage component 200 by the converter 320, so as to charge the energy storage component 200.

[0047] The charging device provided in the embodiment of the present disclosure controls the energy storage component 200 to move relative to the magnetic component 100, so that the magnetoelectric conversion component 300 disposed on the energy storage component 200 cuts the magnetic field magnetic flux lines of the magnetic component 100. Furthermore, the magnetoelectric conversion component 300 generates induced electric energy based on the magnetic field of the magnetic component 100 to charge the energy storage component 200. In this way, when the user finds that the power in the energy storage component 200 is exhausted, the energy storage component 200 can be charged simply and quickly, thereby optimizing the user experience.

[0048] In particular, when the elastic member 400 is used to connect the magnetic component 100 and the energy storage component 200, when the user carries the charging device for exercise (walking or running), the energy storage component 200 and the magnetic component 100 move relative to each other due to inertia. At this time, during the user's exercise, the charging device automatically charges the energy storage component, further optimizing the user experience.

[0049] It should also be noted that when the magnetoelectric conversion component 300 includes a coil 310, the movement amplitude of the magnetoelectric conversion component 300 relative to the magnetic component 100 is different due to the difference in the user's movement amplitude. Furthermore, the amplitude of the magnetic flux lines of the magnetic field of the magnetic component 100 cut by the coil 310 is different. Therefore, the induced current or induced voltage generated by the coil 310 is different. At this time, the coil 310 and the energy storage component 200 are electrically connected through the converter 320, so that the energy storage component 200 receives a stable current or voltage to ensure the charging effect.

[0050] In one embodiment, Figure 1 , Figure 2 As shown, the charging device further includes a guide member 500 connected to the housing 110. The elastic member 400 is connected to the guide member 500 and can be extended and retracted along the length direction of the guide member 500. Optionally, the elastic member 400 includes a spring, and the spring is sleeved outside the guide member 500.

[0051] By limiting the elastic member 400 to expand and contract along the direction of the guide member 500, the energy storage member 200 moves relative to the magnetic assembly 100 in a relatively stable manner. Accordingly, the magnetoelectric conversion assembly 300 disposed on the energy storage member 200 cuts the magnetic flux lines in a stable manner, ensuring that the magnetoelectric conversion assembly 300 outputs a stable current or voltage. In addition, in the case where the charging device includes a plurality of elastic members 400, a matching guide member 500 is provided for each elastic member 400.

[0052] Furthermore, a through hole 210 is provided on the energy storage member 200. One end of the guide member 500 passes through the through hole 210 and is fixedly connected to the housing 110, and the other end of the guide member 500 is limited outside the through hole 210. In this way, the guide member 500 limits the maximum distance that the energy storage member 200 moves relative to the housing 100, thereby preventing the elongation of the elastic member 400 from exceeding the elastic deformation range, thereby ensuring the structural safety of the charging device.

[0053] In one embodiment, Figure 1 As shown, the charging device also includes: a connector 600 connected to the energy storage component 200, and the connector 600 is used to connect an external electronic device. Optionally, the connector 600 includes an edge bent in a direction away from the energy storage component 200 to form a groove structure. When in use, the electronic device is snapped into the groove structure formed by the connector 600. In this way, the charging component and the electronic device form an integrated structure, which is convenient for users to carry.

[0054] In one embodiment, Figure 1 As shown, the charging device also includes a wearable part 700, and the wearable part 700 is connected to the magnetic component 100. Optionally, the wearable part 700 is connected to the shell 110 of the magnetic component 100, for example, it is arranged on the side wall 111 of the shell 110 or on the bottom wall 112 of the shell 110. By setting the wearable part 700, the wearability of the charging device is achieved. The charging component is fixed to the user's arm or leg through the wearable part 700, so that the energy storage part 200 can be charged instantly during the user's exercise, thereby optimizing the portability of the charging device. Optionally, the wearable part 700 is made of flexible fabric to improve wearing comfort.

[0055] Based on the charging device provided above, the present disclosure also provides a charging system. Figure 3 FIG. 1 is a schematic diagram of a charging system according to an exemplary embodiment. Figure 3 As shown, the charging system includes the charging device provided in the first aspect and an electronic device 800. The electronic device 800 is electrically connected to the energy storage component 200 in the charging device to receive the electric energy provided by the energy storage component.

[0056] By using the charging device provided in the embodiment of the present disclosure, the energy storage component in the charging device can be charged in real time during the user's exercise, and then the electronic device can be charged through the energy storage component. The overall process does not affect the user's exercise, and convenient charging is achieved in an outdoor environment, which solves the problem caused by the exhaustion of the outdoor mobile power supply and optimizes the user experience.
