[0032] Preferred embodiments of the present invention will now be described in more detail with reference to the accompanying drawings. While preferred embodiments of the present invention are shown in the drawings, it should be understood that the present invention may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that the present invention will be thorough and complete, and will fully convey the scope of the present invention to those skilled in the art.

[0033] Existing technology discloses a portable multi-functional three-in-one wireless charger, including a first wireless charger. The first wireless charger includes a first bottom shell, a first magnet, a first wireless charging coil, and a first cover. A connection port is provided on one side of the first wireless charger, and a connector is rotatably disposed within the connection port. A second wireless charger is rotatably disposed at one end of the connector. The first and second wireless chargers are rotatably connected via the connector. The third wireless charger is connected to the second wireless charger via a power cable. This design achieves electrical connection with the circuit board while also preventing the charger from falling out. The shape of the first, second, and third wireless chargers is designed so that when they are magnetically connected, they form a spherical shape, making them compact and easy to carry. However, in this wireless charger, the third wireless charger is connected to the second wireless charger via a power cable. This connection method is not only cumbersome in terms of cable routing but also exposes the power cable outside the wireless charger, affecting the overall appearance of the product. Furthermore, the power cable is prone to wear and tear over long-term use, affecting the normal operation of the wireless charger.

[0034] Based on this, this application provides a conductive structure.

[0035] Example 1

[0036] like Figures 1-6 As shown, this embodiment provides a conductive structure, including:

[0037] A rotating shaft 3, with an adapter plate 2 disposed outside the rotating shaft 3, the adapter plate 2 surrounding part or all of the rotating shaft 3;

[0038] The adapter plate 2 is provided with a first contact 21 and a second contact 22, both of which are electrically connected to the adapter plate 2.

[0039] The rotating shaft is used to connect the first component and the second component. When the first component and the second component rotate around the rotating shaft, they respectively connect with the first contact and the second contact, thereby realizing the electrical connection between the first component and the second component.

[0040] Specifically, this conductive structure can be used in a three-in-one wireless charging device. The two wireless charging boards of the device are rotatably connected to the rotating shaft 3, and during rotation, they are electrically connected to the first contact and the second contact, respectively, thus achieving electrical connection between the two different wireless charging boards. This helps simplify the layout of the wireless charging boards. Furthermore, the first and second components can rotate from 0 degrees to 360 degrees via the rotating shaft 3. That is, regardless of the rotation angle, the first and second components can achieve electrical connection through the adapter plate 2 without any open circuit.

[0041] Specifically, in the conductive structure of this application, an adapter plate 2 is arranged around the outside of the rotating shaft 3. The adapter plate 2 can partially or completely surround the rotating shaft 3 according to actual design requirements. For example, in a relatively simple wireless charging dock design, the adapter plate 2 is chosen to surround 3 / 4 of the rotating shaft 3, which can meet the conductivity requirements while saving materials and space. The first contact 21 and the second contact 22 can achieve a stable electrical connection with the adapter plate 2 through welding or other reliable electrical connection methods. Taking a common welding process as an example, ensure that the solder joint is strong and has low resistance to guarantee good conductivity.

[0042] The aforementioned conductive structure can be used in a wireless charging device 100, for example, in a wireless charging device 100 having a base and a movable support, wherein the movable support and the base are rotatably connected via a pivot 3. When this conductive structure is used in the wireless charging device 100, the base portion of the wireless charging device 100 is connected to the first contact 21 of the adapter plate 2 via a wire, and the movable support portion of the wireless charging device 100 (such as an adjustable-angle support) is connected to the second contact 22 of the adapter plate 2 via another wire. When the wireless charging device 100 is powered on, current flows from the power source into the base, is transmitted to the adapter plate 2 via the wire connected to the first contact 21, then to the second contact 22 via the adapter plate 2, and finally to the movable support portion via the wire connected to the second contact 22, thus realizing the effective transmission of electrical energy between different components. By setting an adapter plate 2 and a conductive structure for the contacts outside the rotating shaft 3, the transmission of electrical energy between different components such as the base and the movable bracket can be achieved simply by connecting the first contact 21 and the second contact 22 with two wires respectively. This greatly simplifies the wiring process and makes the internal wiring of the wireless charging device 100 clear and concise, effectively overcoming the problem of complex traditional wiring. Due to the simplified wiring, the wireless charging device 100 no longer needs to reserve a lot of space for wiring, so other electronic components can be arranged more rationally, and the overall structure of the wireless charging device 100 can be made more compact.

[0043] In this embodiment, the conductive structure further includes a mounting sleeve 1, which has a mounting cavity 11. The rotating shaft 3 is disposed in the mounting cavity 11, and the adapter plate 2 is disposed on the mounting sleeve 1 and surrounds the rotating shaft 3.

[0044] More specifically, multiple adapter plates 2 are provided on the mounting sleeve 1, and the multiple adapter plates 2 are arranged in parallel and along the axial direction of the mounting sleeve 1;

[0045] Each of the adapter plates 2 is provided with at least one first contact 21 and at least one second contact 22.

[0046] Mounting sleeve 1 provides better fixation and protection for the rotating shaft 3 and related conductive components. A dedicated mounting cavity 11 is provided within mounting sleeve 1, allowing the rotating shaft 3 to be precisely positioned within this cavity, thus ensuring stable operation of the rotating shaft 3. Multiple adapter plates 2 enable multi-point electrical connections, thereby improving the reliability of electrical connections between different components.

[0047] In this embodiment, the adapter plate 2 is arranged in a ring around the outer periphery of the rotating shaft 3, and the adapter plate 2 is provided with mounting holes, and one end of the second contact 22 is fixedly connected to the mounting holes.

[0048] Mounting holes are provided on the adapter plate 2 for connecting related components, such as the second contact 22. The first contact 21 can be integrally formed with the adapter plate 2, for example, if the adapter plate 2 is made of conductive material. One end of the second contact 22 is fixedly connected to the mounting hole, for example, by screw fastening or riveting, to ensure a firm connection and good conductivity between the second contact 22 and the adapter plate 2. In one embodiment, two first contacts 21 are provided on one adapter plate 2, and three mounting holes are provided accordingly. Each mounting hole is precisely fixedly connected to one second contact 22, and the layout is reasonable according to the conductivity requirements of different components. Depending on the actual application scenario and performance requirements, multiple adapter plates 2 arranged in parallel and distributed along the axis of the mounting sleeve 1 can be provided on the mounting sleeve 1.

[0049] Example 2

[0050] like Figures 1-6 As shown, this embodiment provides a wireless charging device, including the conductive structure described above.

[0051] In this embodiment, the wireless charging device 100 includes a first wireless charger 110, a second wireless charger 120, and a third wireless charger 130. The conductive structure is provided between the first wireless charger 110 and the second wireless charger 120, and the conductive structure is provided between the second wireless charger 120 and the third wireless charger 130.

[0052] The first wireless charger 110 and the second wireless charger 120, and the second wireless charger 120 and the third wireless charger 130 are all rotatably connected via the rotating shaft 3.

[0053] More specifically, in this embodiment, the first wireless charger 110 is provided with a motherboard 1102, and the side wall of the first wireless charger 110 is provided with a first interface 1101, which is electrically connected to the motherboard 1102; the first interface 1101 may be a type-c interface, used to power the entire device.

[0054] The second wireless charger 120 is equipped with a watch module 1201, which is electrically connected to the second contact 22, and the motherboard 1102 is electrically connected to the first contact 21.

[0055] The wireless charging device 100 of this application comprises a first wireless charger 110, a second wireless charger 120, and a third wireless charger 130. This wireless charging device 100 is a three-in-one wireless charger that can be used for wireless charging of watches, earphones, and mobile phones. To achieve flexible connection and power transfer between the chargers, a conductive structure is provided between the first wireless charger 110 and the second wireless charger 120, and similarly, a conductive structure is provided between the second wireless charger 120 and the third wireless charger 130. Furthermore, the first wireless charger 110 and the second wireless charger 120, as well as the second wireless charger 120 and the third wireless charger 130, are all rotatably connected via a pivot 3. This rotatable connection allows the angles of the chargers to be adjusted according to the actual usage scenario, increasing ease of use.

[0056] In one specific implementation, the first wireless charger 110 is used to charge headphones, the second wireless charger 120 is used to charge a watch, and the third wireless charger 130 is used to charge a mobile phone. By rotating the hinge 3 to different angles of the wireless chargers, the device can be adapted to the charging needs of different products.

[0057] It can be understood that the first wireless charger 110 is the bottom layer structure of the device, the second wireless charger 120 is the middle layer structure, and the third wireless charger 130 is the top layer structure.

[0058] Furthermore, the second wireless charger 120 is provided with an anti-slip plate, which has anti-slip texture. The anti-slip plate is located on the surface of the second wireless charger 120, and the anti-slip texture on the anti-slip plate can contact the bottom of the product. When the product to be charged is placed on the surface of the second wireless charger 120, the anti-slip texture can make the product adhere to the surface of the second wireless charger 120 and not easily slip off, thereby enabling stable charging.

[0059] Furthermore, the third wireless charger 130 is provided with a mutual inductance coil 1301, which is electrically connected to a first contact 21 of a conductive structure. A magnetic ring 1302 is provided around the mutual inductance coil 1301. The mutual inductance coil 1301 is used to realize wireless charging of the mobile phone, and the magnetic ring 1302 is used to attract the mobile phone.

[0060] The wireless charging device 100 provided in this application includes the above-mentioned conductive structure. The wireless charging device 100 uses the above-mentioned conductive structure to realize the mutual electrical connection between different components, which can simplify the wiring method, thereby making the structure of the entire charging device more compact and reducing the possibility of damage to the line due to external forces.

It should also be understood that, for ease of description, the dimensions of the various parts shown in the drawings are not drawn to actual scale. Techniques, methods, and devices known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and devices should be considered part of the specification. In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following drawings denote similar items; therefore, once an item is defined in one drawing, it need not be further discussed in subsequent drawings. In the description of this application, it should be understood that the orientation or positional relationship indicated by directional terms such as "front, back, up, down, left, right", "horizontal, vertical, horizontal" and "top, bottom" is usually based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing this application and simplifying the description.

[0062] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures.

Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0063] Furthermore, it should be noted that the use of terms such as "first" and "second" to define components is merely for the purpose of distinguishing the corresponding components.
