[0036] The embodiments of this application will now be described in detail. Examples of these embodiments are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this application, and should not be construed as limiting this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0037] In the description of this application, it should be understood that the features referred to by the terms "first" and "second" may explicitly or implicitly include one or more of those features.

[0038] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0039] The charging dock has a built-in transmitting coil, and the charging case has a built-in receiving coil. The basic principle of wireless charging is that when the transmitting coil and the receiving coil are close together, the transmitting coil generates a certain current in the receiving coil through electromagnetic induction based on the alternating current of a certain frequency, thereby transferring energy from the transmitting end to the receiving end, and thus starting to supply power from the charging dock to the charging case.

[0040] In principle, the presence of magnetic or metallic components in the charging case will affect wireless charging efficiency. Generally, magnetic components affect wireless charging by about 5%, meaning the efficiency may drop from 60% to around 55%. Low efficiency directly leads to longer charging times, which in turn causes increased temperature rise inside the charging case, ultimately resulting in a poor user experience.

[0041] To solve the above problems, such as Figure 1 , Figure 2 and Figure 3 As shown, the charging box in this embodiment includes: a box body 1, a magnetic component 3, a driving component, and a first coil 2.

[0042] The driving component is located in the housing 1 and is used to drive the magnetic component 3 to move.

[0043] The magnetic component 3 is movably disposed in the first position of the housing 1, that is, the magnetic component 3 can move relative to the housing 1 under the drive of the driving component.

[0044] The magnetic component 3 is used to drive the electronic device to move relative to the charging case. The case 1 has a receiving cavity for placing the electronic device. The magnetic component 3 can be a magnet; for example, when the electronic device is placed in the receiving cavity, the magnetic component 3 can attract the electronic device to prevent it from moving relative to the case 1.

[0045] Alternatively, the magnetic component 3 can be a magnet in the charging case used for wireless charging positioning with the charging dock, etc. The function of the magnetic component 3 is not limited here.

[0046] The first coil 2 is disposed on the box 1. The first coil 2 is used to charge the charging box or electronic device. The first coil 2 has a first distance from the magnetic component 3.

[0047] It should be noted that the charging box may be equipped with a battery module. In this case, the first coil 2 can first supply power to the battery module, and when the electronic device needs to be charged, the battery module will then supply power to the electronic device.

[0048] When the first coil 2 is charging the charging box or electronic device, the driving member drives the magnetic member 3 to move to the second position of the box 1. When the magnetic member 3 is in the second position, the magnetic member 3 has a second distance from the first coil 2, which is greater than the first distance.

[0049] For example, the first distance is 20mm, and the second distance is 50mm.

[0050] It is understandable that when the magnetic component 3 is in the first position of the box 1, if the first coil 2 charges the charging box or electronic device, the magnetic flux of the magnetic component 3 will affect the magnetic flux of the first coil 2, thereby affecting the charging efficiency.

[0051] In this embodiment of the application, when the first coil 2 is charging the charging box or electronic device, the driving member drives the magnetic member 3 to move from the first position of the box body 1 to the second position of the box body 1. At this time, the magnetic member 3 is away from the first coil 2, thereby reducing the influence of the magnetic flux of the magnetic member 3 on the magnetic flux of the first coil 2, improving the charging efficiency, reducing the charging time, and reducing the heat generated by wireless charging, thereby achieving the purpose of effectively controlling the temperature of the charging box.

[0052] In an optional embodiment, the driving component can be a structural component with a driving function. For example, the driving component can be a telescopic cylinder or an electric push rod. That is, when the first coil 2 is charging the charging box or electronic device, the driving component can drive the magnetic component 3 to move from the first position of the box 1 to the second position of the box 1.

[0053] In an optional embodiment, the driving element includes a second coil 4, and the first coil 2 is electrically connected to the second coil 4.

[0054] When the first coil 2 is charging the charging box or electronic device, the first coil 2 supplies power to the second coil 4. Under the action of the second coil 4, the magnetic component 3 moves from the first position to the second position.

[0055] It should be noted that the second coil 4 is equivalent to an electromagnetic component. When the second coil 4 is energized, a force can be generated between the second coil 4 and the magnetic component 3, allowing the magnetic component 3 to move from the first position to the second position. This force can be either repulsive or attractive.

[0056] In this embodiment, the second coil 4 serves as a driving element. When the first coil 2 is charging the charging box or electronic device, the first coil 2 can simultaneously supply power to the second coil 4. This allows the magnetic element 3 to move away from the first coil 2 while the first coil 2 is charging the charging box or electronic device. This driving structure is simple, improves the charging effect, and eliminates the need for an additional power supply for the operation of the driving element.

[0057] In an optional embodiment, the charging box further includes a rectifier module. The first coil 2 is electrically connected to the second coil 4 through the rectifier module. The current in the first coil 2 is rectified by the rectifier module to charge the charging box or electronic device.

[0058] In other words, the AC power in the first coil 2 can be rectified into DC power by the rectifier module, thereby enabling the charging box or electronic devices to be charged.

[0059] When the first coil 2 is charging the charging box or electronic device, the current in the first coil 2 is rectified by the rectifier module to power the second coil 4. The current in the second coil 4 generates a magnetic field, which drives the magnetic component 3 to move from the first position to the second position.

[0060] In other words, the alternating current in the first coil 2 is rectified into direct current by the rectifier module, which can then power the second coil 4, causing the second coil to generate a magnetic field due to the electromagnetism effect.

[0061] In this embodiment of the application, by setting a rectifier module, the first coil 2 can charge the charging box or electronic device while also supplying power to the second coil 4, so that the second coil 4 generates a magnetic field, which in turn drives the magnetic component 3 to move. The structure is simple, but it can achieve two uses of one power source.

[0062] In optional embodiments, such as Figure 1 and Figure 2 As shown, the charging case also includes an elastic element 5, which has a first state and a second state. The magnetic element 3 is disposed in the first position through the elastic element 5. When the magnetic element 3 moves from the first position to the second position, the elastic element 5 is in the second state.

[0063] When the first coil 2 is not charging the charging box or electronic device, the elastic element 5 can drive the magnetic element 3 to move from the second position to the first position.

[0064] The elastic element can be a sheet, spring, or other device with telescopic capability, and is not specifically limited here.

[0065] It should be noted that when the first coil 2 is charging the charging box or electronic device, the current in the first coil 2 is rectified by the rectifier module to power the second coil 4. Under the action of the second coil 4, the magnetic component 3 moves from the first position to the second position, at which time the elastic component switches from the first state to the second state. When the first coil 2 is not charging the charging box or electronic device, the second coil 4 is in a de-energized state, that is, there is no force between the second coil 4 and the magnetic component 3, and the elastic component can drive the magnetic component to move from the second position to the first position. It is particularly important to point out that the first state can be the original length state and the second state can be the extended state; or, the first state can be the original length state and the second state can be the compressed state.

[0066] In this embodiment, when the second coil 4 is de-energized, the magnetic element 3 can return to its original position via the elastic element 5. The structure is simple, requires no additional driving force, and can save energy.

[0067] In an optional embodiment, the first coil 2 and the second coil 4 are arranged opposite to each other, and the magnetic element 3 is located between the first coil 2 and the second coil 4.

[0068] When the first coil 2 is charging the charging box or electronic device, the first coil 2 can also supply power to the second coil 4. When the second coil 4 is energized, the polarity of the second coil 4 facing the magnetic element 3 is opposite to the polarity of the magnetic element 3 facing the second coil 4.

[0069] For example, the magnetic component 3 is the N pole facing the second coil. When the second coil 4 is energized, the side of the second coil 4 facing the magnetic component becomes the S pole. An attraction is generated between the magnetic component 3 and the second coil 4. At this time, the magnetic component 3 moves away from the first coil 2. After the second coil 4 is de-energized, the force between the magnetic component 3 and the second coil 4 disappears, and the elastic component 5 can drive the magnetic component 3 to reset.

[0070] In an optional embodiment, the first coil 2 and the second coil 4 are located on the same side of the housing 1, and the magnetic element 3 is located on the other side of the housing 1.

[0071] For example, the first coil 2 and the second coil 4 are located on the right side of the box 1, and the magnetic component 3 is located on the left side of the box 1.

[0072] When the first coil 2 is charging the charging box or electronic device, the first coil 2 can also supply power to the second coil 4. When the second coil 4 is energized, the polarity of the second coil 4 facing the magnetic element 3 is the same as the polarity of the magnetic element 3 facing the second coil 4.

[0073] For example, the magnetic component 3 is the N pole facing the second coil 4. When the second coil 4 is energized, the side of the second coil 4 facing the magnetic component 3 becomes the N pole, and a repulsive force is generated between the magnetic component 3 and the second coil 4. At this time, the magnetic component 3 moves away from the first coil 2. After the second coil 4 is de-energized, the force between the magnetic component 3 and the second coil 4 disappears, and the elastic component 5 can drive the magnetic component 3 to reset.

[0074] In an optional embodiment, the driving element includes an electro-deformation element, the first coil 2 is electrically connected to the electro-deformation element, and the magnetic element 3 is disposed at a first position through the electro-deformation element.

[0075] When the first coil 2 is charging the charging box or electronic device, the first coil 2 supplies power to the electro-deformation element. Under the action of the electro-deformation element, the magnetic element 3 moves from the first position to the second position.

[0076] When the first coil 2 is not charging the charging box or electronic device, the electro-deformation element can drive the magnetic element 3 to move from the second position to the first position.

[0077] The electro-deformation component can be a shape memory alloy or a piezoelectric ceramic, without specific limitations.

[0078] When the electro-deformation element is energized, it can drive the magnetic element to move from the first position to the second position. When the electro-deformation element is de-energized, it can drive the magnetic element to move from the second position to the first position.

[0079] For example, when the electro-deformer is energized, it is in an extended state, and the magnetic element 3 is far away from the first coil 2. When the electro-deformer is de-energized, it is in a shortened state, and the electro-deformer can drive the magnetic element 3 to reset.

[0080] In this embodiment, the electro-deformable element can move the magnetic element 3 away from or closer to the first coil 2, thereby enabling the magnetic element 3 to move away from the first coil 2 while charging the charging box or electronic device.

[0081] In an optional embodiment, the charging box further includes a rectifier module. The first coil 2 is electrically connected to the electro-deformation element through the rectifier module. The current in the first coil 2 is rectified by the rectifier module to charge the charging box or electronic device.

[0082] In other words, the AC power in the first coil 2 can be rectified into DC power by the rectifier module, thereby enabling the charging box or electronic devices to be charged.

[0083] When the first coil 2 is charging the charging box or electronic device, the current in the first coil 2 is rectified by the rectifier module to power the electro-deformation element. Under the action of the electro-deformation element, the magnetic element 3 moves from the first position to the second position. When the first coil 2 is not charging the charging box or electronic device, the magnetic element 3 moves from the second position to the first position under the action of the electro-deformation element.

[0084] In other words, the AC power in the first coil 2 can be rectified into DC power by the rectifier module, thereby powering the electro-deformation device.

[0085] In this embodiment of the application, by setting a rectifier module, the first coil 2 can simultaneously charge the charging box or electronic device and power the electro-deformation component. The structure is simple, yet it can achieve dual power supply.

[0086] In an optional embodiment, the charging box further includes a guide shaft disposed inside the box body 1, and a magnetic component 3 is slidably disposed on the guide shaft.

[0087] The guide shaft can be made of plastic, and the guide shaft and the box 1 adopt an integral molding structure.

[0088] It should be noted that, driven by the driving component, the magnetic component 3 can move along the axial direction of the guide shaft. In other words, by sliding the magnetic component 3 on the guide shaft, a constraint can be applied to the magnetic component 3 to ensure the uniqueness of the direction of movement of the magnetic component 3.

[0089] In an optional embodiment, to further ensure the uniqueness of the moving direction of the magnetic component 3, the magnetic component 3 is provided with a mounting hole, through which the guide shaft passes.

[0090] It should be noted that there can be two guide shafts, and the magnetic component 3 has two mounting holes. In this case, the guide shafts are connected to the mounting holes one by one.

[0091] In addition, this application embodiment also provides a charging device, including: a charging base and the above-mentioned charging box.

[0092] The charging base includes a third coil, and the first coil 2 is energized when the third coil is opposite to the first coil 2.

[0093] In this embodiment, when the first coil 2 is close to the third coil, the third coil can generate a certain current in the first coil 2 through electromagnetic induction based on an alternating current of a certain frequency, thereby transferring point energy from the transmitting end to the receiving end, and then starting to supply power from the charging base to the charging box. When the charging box is being charged, the first coil 2 can supply power to the driving component, and the driving component drives the magnetic component 3 away from the first coil 2. At this time, the magnetic flux of the magnetic component 3 can be prevented from being neutralized with the magnetic flux of the first coil 2. When the charging box is fully charged, the first coil 2 stops supplying power to the driving component, and the driving component drives the magnetic component to reset, thereby improving charging efficiency, reducing charging time, and reducing the heat generated by wireless charging, thereby achieving the purpose of effectively controlling the temperature of the charging box.

For example, the electronic device can be a TWS (True Wireless Stereo) headset, and the embodiments of this application do not specifically limit the specific type of electronic device.
