[0029] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0030] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0031] like Figure 1 As shown, this application provides a magnetic charging device, including a housing 1, which is used to protect the safety of internal electronic components, and multiple interfaces 2 are provided on the housing 1, which are 2.5-inch DC sockets and Micro-USB interfaces to facilitate input to the charging device.

[0032] Furthermore, a PCB circuit board (not shown in the figure) is installed inside the housing 1. The PCB circuit board adopts a 0805 package, the voltage programming resistor R21 is designed to be 100K ohms, R22 is designed to be 13.6K ohms, the output voltage Vout=0.6*(1+R21 / R22)=5V, and the entire back of the PCB circuit board is covered with copper foil as GND in the circuit. At the same time, the power circuit uses copper foil instead of wiring, thus having a higher current carrying capacity and strong heat dissipation capacity. The dimensions of the PCB circuit board are 30mm x 43mm.

[0033] like Figures 2-4 As shown, in order to enable the charging device to charge batteries of different shapes, two sets of wires 3 are provided in the housing 1, and a magnetic head 4 is provided at the output end of the wires 3. The magnetic head 4 includes an insulating layer 43 fixedly provided at the output end of the wires 3, and a through hole is provided at the upper end of the insulating layer 43.

[0034] Furthermore, a magnetic outer core 42 is fixedly disposed inside the insulating layer 43. The magnetic outer core 42 is composed of two parts, upper and lower, so that the battery can be attracted during subsequent charging.

[0035] Meanwhile, a small hole is provided at the upper end of the magnetic outer core 42, and a copper core 40 is slidably disposed in the small hole. The copper core 40 is adapted to the two electrodes of the battery so that the charging operation can be carried out smoothly.

[0036] Furthermore, a spring 41 is fixedly installed at the lower end inside the magnetic outer core 42. The other end of the spring 41 is fixedly connected to the copper core 40 so that the copper core 40 can be pressed tightly against the two poles of the battery by the clamping force provided by the spring 41 to perform charging operation.

[0037] like Figures 2-3 As shown, in order to facilitate the storage of the wire 3 when the charging device is not in use, storage components 5 are provided on both sides of the housing 1. The storage components 5 include a fixed mounting frame 50, and a square slot 51 is provided on the upper end of the mounting frame 50. The size of the square slot 51 matches the size of the magnetic head 4 in the vertical state, so that the magnetic head 4 can pass through the square slot 51 in the vertical state.

[0038] Meanwhile, a take-up roller 52 is rotatably mounted on the fixed frame 50. The take-up roller 52 is used to take up the wire 3. The middle part of the wire 3 is wound on the take-up roller 52. At the same time, the output end of the wire 3 passes through the square slot 51 so that it can be locked in the square slot 51 by the magnetic suction head 4 of the output end of the wire 3, thereby achieving the purpose of storing the wire 3.

[0039] When charging is needed, simply rotate the take-up roller 52 to release the wire 3, then pull the wire 3 to press the magnetic head 4 firmly against the two poles of the battery to start the charging operation. After charging is complete, simply rotate the take-up roller 52 in the opposite direction to rewind the wire 3, and pull the wire 3 onto the take-up roller 52 until the magnetic head 4 is engaged in the square slot 51 to complete the storage.

[0040] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
