Detailed Implementation

[0029] The present invention will be further described below with reference to specific embodiments and accompanying drawings.

[0030] See Figure 1-8 As shown, a detachable and combinable wireless charger includes an input component 1 and an output component 2, each having a first housing 10 and a second housing 10 that are independent of each other. The input component 1 can be used to plug into a power outlet to obtain power (e.g., AC power), and the output component 2 is used to output power to charge an external device 5.

[0031] The input component 1 includes an AC input interface 101 and at least one AC-DC power conversion module 102. The AC input interface 101 can be an AC plug for insertion into a power socket to draw AC power, which is then converted to DC power by the AC-DC power conversion module 102 and delivered to the output component 2. Alternatively, the AC input interface 101 can also be an AC power interface for plug insertion to draw power.

[0032] The output component 2 includes at least one rechargeable battery 201 and at least one wireless charging module 202 electrically connected to the rechargeable battery 201. The wireless charging module 202 includes at least one wireless charging drive module 203, at least one wireless charging coil 204, and at least one first permanent magnet 205 for alignment when charging the external device 5, so that the output component 2 can perform wireless charging function for the external device 5. When the input component 1 and the output component 2 are combined, the AC-DC power conversion module 102 converts the AC power obtained from the AC power input interface 101 into DC power and sends it to the rechargeable battery 201 of the output component 2 to charge the rechargeable battery 201. Then, the wireless charging module 202 performs wireless charging function for the external device 5 through the wireless charging coil 204. Alternatively, the AC-DC power conversion module 102 converts the AC power obtained from the AC input interface 101 into DC power and sends it to the wireless charging drive module 203 of the output component 2. Then, the wireless charging module 202 performs wireless charging on the external device 5 through the wireless charging coil 204.

[0033] In this embodiment, the first housing 10 is provided with at least one set of first positive conductors 111 and first negative conductors 112 electrically connected to the AC-DC power conversion module 102. The first positive conductors 111 and first negative conductors 112 are exposed on the first housing 10 for later connection to the output component 2. Correspondingly, the second housing 20 is provided with at least one set of second positive conductors 211 and second negative conductors 212 electrically connected to the rechargeable battery 201. The second positive conductors 211 and second negative conductors 212 are exposed on the second housing 20 for later connection to the input component 1. In actual use, when the output component 2 and the input component 1 are combined, the first positive conductors 111 and second positive conductors 211 correspond to and are in contact with each other, and the first negative conductors 112 and second negative conductors 212 correspond to and are in contact with each other. When the output component 2 is in contact with the input component 1, the AC-DC power conversion module 102 and the rechargeable battery 201 form an electrical connection, enabling the wireless charging module 202 to wirelessly charge the external device 5. This wireless charging mode is powered by AC, i.e., by the AC-DC power conversion module 102. Alternatively, when the output component 2 is disconnected from the input component 1, the first positive conductor 111 and the second positive conductor 211 are disconnected, and the first negative conductor 112 and the second negative conductor 212 are disconnected, thus breaking the electrical connection between the AC-DC power conversion module 102 and the rechargeable battery 201. At this time, the rechargeable battery 201 supplies power to the wireless charging module 202, allowing the output component 2 to continuously wirelessly charge the external device 5. This wireless charging mode is powered by the battery, i.e., by the rechargeable battery 201, enabling the present invention to achieve wireless charging functionality through dual-mode power supply. Therefore, whether the output component and the input component are in a separate state or a combined state, the output component can continue to wirelessly charge the external device 5. Even without a power outlet, the wireless charger of this invention can wirelessly charge the external device 5. Furthermore, since the output component and the input component are separable, the output component can be detached from the input component and used independently to wirelessly charge the external device 5. This results in a smaller size / volume, easier storage, and greater flexibility and convenience in use.

[0034] The assembly structure of the output component 2 and the input component 1 can be as follows: a mounting groove 105 is provided on the first housing 10 of the input component 1, and the output component 2 is embedded in the mounting groove 105. In order to facilitate the quick removal of the output component 2 relative to the mounting groove 105, multiple notches 106 are provided at the opening of the mounting groove 105. The output component 2 is partially exposed in the notches 106, which makes it convenient for users to use their fingers to pinch the output component 2 through the notches 106 to quickly remove the output component 2 relative to the input component 1. This makes the operation more convenient and easier to use.

[0035] Combination Figure 1 As shown, the input component 1 is provided with a USB charging interface 104, which is powered by an AC-DC power conversion module 102 and is used to output power to the outside, such as connecting a USB charging cable to charge an external device 5.

[0036] To ensure a more stable assembly structure after the output component 2 and the input component 1 are assembled together, the following settings are also made:

[0037] In this embodiment, combined with Figure 3 As shown, the first housing 10 of the input component 1 is provided with at least one second permanent magnet 113, and the second housing 20 of the output component 2 is provided with at least one magnetic metal 213. When the input component 1 and the output component 2 are brought into contact, the second permanent magnet 113 attracts the magnetic metal 213, causing the second housing 20 to be close to the first housing 10. This ensures that the output component 2 is more stably installed in the mounting groove 105 of the first housing 10, and that the first positive conductor 111 and the second positive conductor 211 are in contact with each other, and that the first negative conductor 112 and the second negative conductor 211 are in contact with each other, thus ensuring the stability of the electrical connection.

[0038] Under the same logic, the second permanent magnet 113 can also be disposed on the second housing 20, and the magnetic metal 213 is disposed on the first housing 10. When the input component 1 and the output component 2 are close, the second permanent magnet 113 attracts the magnetic metal 213, so that the first housing 10 is close to the second housing 20. This is another implementation method, as another embodiment.

[0039] Combination Figure 3As shown, a third permanent magnet 114 is provided below the first positive conductor 111 of the input component 1, and the first negative conductor 112 is a magnetic metal; a fourth permanent magnet 214 is provided below the second negative conductor 212 of the output component 2, and the second positive conductor 211 is a magnetic metal; when the third permanent magnet 114 and the fourth permanent magnet 214 face each other, their magnetic poles are the same, and therefore they repel each other; when the input component 1 and the output component 2 are combined, the third permanent magnet 114 attracts the second positive conductor 211, and the fourth permanent magnet 214 attracts the first negative conductor 112, thereby achieving the purpose of preventing mistaken insertion and thus realizing the function of preventing reverse insertion. At the same time, it can also ensure that the first positive conductor 111 and the second positive conductor 211 form a more stable electrical connection function, and ensure that the first negative conductor 112 and the second negative conductor 212 form a more stable electrical connection function.

[0040] Under the same logic, the third permanent magnet 114 and the fourth permanent magnet 214 can also be respectively disposed below the first negative conductor 112 and the second positive conductor 211 to provide the same attraction and repulsion functions and ensure that the positive and negative conductors are in correct contact. This is another implementation method, as another embodiment.

[0041] In some other embodiments, combined with Figure 4As shown, the first positive conductor 111 and the first negative conductor 112 of the input component 1 each have a third permanent magnet 114 below them; the second positive conductor 211 and the second negative conductor 212 of the output component 2 each have a fourth permanent magnet 214 below them; when the third permanent magnet 114 below the first positive conductor 111 and the fourth permanent magnet 214 below the second negative conductor 212 face each other, their magnetic poles are the same, therefore they repel each other; when the third permanent magnet 114 below the first negative conductor 112 and the fourth permanent magnet 214 below the second positive conductor 211 face each other, their magnetic poles are the same, therefore they repel each other; the first positive conductor 111... When the third permanent magnet 114 below the first positive conductor 112 and the fourth permanent magnet 214 below the second positive conductor 211 face each other, their magnetic poles are opposite, and therefore they attract each other. Similarly, when the third permanent magnet 114 below the first negative conductor 112 and the fourth permanent magnet 214 below the second negative conductor 212 face each other, their magnetic poles are opposite, and therefore they attract each other. This complete magnetic pole matrix prevents mistake-proofing, achieving a better mistake-proofing function and preventing reverse insertion. It also ensures a more stable electrical connection between the first positive conductor 111 and the second positive conductor 211, and between the first negative conductor 112 and the second negative conductor 212. The output component 2 is equipped with a USB interface 206 and is electrically connected to the wireless charging module 202. It can also output power externally through the USB interface 206, for example, by connecting a USB charging cable to charge an external device 5.

[0042] The charging circuit module 103 of the rechargeable battery 201 in the output component 2 is disposed in the input component 1; the AC-DC power conversion module 102 of the input component 1 is electrically connected to at least one of the charging circuit modules 103; the charging circuit module 103 is electrically connected to the first positive conductor 111 and the first negative conductor 112. When there are two sets of charging circuit modules 103, there are also two sets of the corresponding first positive conductor 111 and the first negative conductor 112, and the electrical connection effect is better.

[0043] In other embodiments, the first positive conductor 111 of the input component 1 is a magnetic metal, with the second permanent magnet 113 disposed below it, and located at the center of the opposite surfaces when the input component 1 and the output component 2 are combined; Figure 5As shown, the first negative conductor 112 is a conductive spring arm 115; the second positive conductor 211 of the output component 2 is the magnetic metal 213, and is located at the center of the opposite surface when the input component 1 and the output component 2 are combined; the second negative conductor 212 is a ring-shaped member 215; when the output component 2 approaches the input component 1, the second permanent magnet 113 attracts the second positive conductor 211 to correct the relative position of the input component 1 and the output component 2 and bring them close together, while the conductive spring arm 115 contacts the ring-shaped member 215; when the output component 2 rotates relative to the input component 1, the second permanent magnet 113 maintains its attraction to the second positive conductor 211, and the conductive spring arm 115 remains in contact with the ring-shaped member 215, thereby achieving rotational contact to meet different usage requirements. The output component 2 is provided with a USB interface 206 and is electrically connected to the wireless charging module 202, and it can also output power externally through the USB interface 206, for example, by connecting a USB charging cable to charge an external device 5.

[0044] The AC input interface 102 of the input component 1 can be any one of IEC interface, national standard plug, national standard plug with cable, or AC interface, and can be selected and installed according to actual usage requirements.

[0045] The first positive conductor 111, the first negative conductor 112, the second positive conductor 211, and the second negative conductor 212, etc., are all conductors including but not limited to conductive sheets, conductive springs, conductive clips, convex conductors, cylindrical conductors, or block conductors. That is, the first positive conductor, the first negative conductor, the second positive conductor, and the second negative conductor are any one of conductive sheets, conductive springs, conductive clips, convex conductors, cylindrical conductors, or block conductors. The annular component 215 includes a planar annular body or a cylindrical annular body with axial height, and different annular components 215 can be used according to actual needs.

[0046] The lower end of the first housing 10 is also provided with a bracket 3 for supporting the external device 5, so as to ensure that the external device 5 and the wireless charging module 202 are accurately aligned, and the wireless charging module 202 wirelessly charges the external device 5.

[0047] Furthermore, the bracket 3 can be adjusted in height relative to the first housing 10 so as to support external devices 5 of different sizes, and ensure that the external device 5 is accurately aligned with the wireless charging module 202, and that the wireless charging module 202 wirelessly charges the external device 5.

[0048] The aforementioned external device 5 is a mobile phone or other wirelessly rechargeable electronic product.

[0049] In summary, whether the output component and input component are in a separate or combined state, the output component can wirelessly charge the external device 5. Even without a power outlet, the wireless charger of this invention can wirelessly charge the external device 5. Furthermore, since the output component and input component are separable, the output component can be detached from the input component and used independently to wirelessly charge the external device 5. This results in a smaller size / volume, easier storage, and greater flexibility and convenience in use.
