Description
Technical Field
[0001] This utility model relates to the field of electric bicycle accessories, and more specifically, to a magnetic power connection component that can be quickly plugged in and unplugged. Background Technology
[0002] With increasing environmental awareness, bicycles are becoming a more popular green mode of transportation. A bicycle, also known as a pedal bike or cyclist, is a small, typically two-wheeled land vehicle, usually propelled by pedals. Based on the working characteristics of its components, it can be broadly divided into a steering system, a drive system, and a braking system.
[0003] Traditional bicycles primarily rely on human power, which limits their usability and convenience to some extent. To address this issue, various types of electric bicycles have emerged on the market, with battery-powered bicycles being particularly popular.
[0004] Current battery and controller connections still rely on traditional mating methods. The user plugs the battery into a socket, requiring them to align the plug with the socket and insert it firmly. Furthermore, to prevent detachment, many solutions add a threaded end cap to the plug, which connects to a threaded socket. Therefore, existing connection methods are cumbersome and inconvenient to operate. Utility Model Content

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.
[0026] Please see Figure 1-5 A quick-plug magnetic power connector assembly includes a plug body 1 and a socket body 25. The plug body 1 has an L-shaped structure, consisting of a plug boss 2 and a plug handle 3. A plug protrusion 4 is provided between the plug boss 2 and the plug handle 3. The plug boss 2 has a cylindrical structure with a bottom diameter of 18 cm. Two discharge holes 6 are provided in the middle area of the top surface of the plug boss 2. Two signal holes 7 and two signal holes 8 are provided on the upper and lower sides of the two discharge holes 6, respectively. A waterproof rubber ring 5 is provided on the side wall of the plug boss 2. A ring magnet 14 is embedded in the plug boss 2. Anti-slip strips 11 are provided on the front and rear surfaces of the plug handle 3.
[0027] The socket body 25 consists of a socket body mounting surface 22, a conductive post mounting surface 16, and a socket body tail end 26. The middle part of the socket body mounting surface 22 is a cylindrical cavity structure, and the bottom diameter of the cylindrical cavity of the socket body mounting surface 22 is 20cm. Two discharge posts 17 are provided in the middle area of the conductive post mounting surface 16. Two signal plugs 18 and two signal plugs 19 are respectively provided on the upper and lower sides of the two discharge posts 17. On the other side of the socket body tail cavity 28 in the socket body tail end 26, opposite to the conductive post mounting surface 16, there is a ring magnet second mounting boss 29. A ring magnet second 27 is provided on the side wall of the ring magnet second mounting boss 29.
[0028] Two matching limiting slots 10 are opened on the left side of the two discharge sockets 6, and a matching limiting slot 9 is opened on the right side of the two discharge sockets 6. A matching limiting head 20 is provided on the left side of the two discharge columns 17, and two matching limiting heads 21 are provided on the right side of the two discharge columns 17. The matching limiting slot 9 is wedged with the matching limiting head 20, and the matching limiting slot 10 is wedged with the matching limiting head 21.
[0029] The upper edge of the socket body mounting surface 22 has four socket body mounting holes 23. The socket body 25 is fixedly mounted on the socket mounting housing 15 through the socket body mounting holes 23. The socket body mounting surface 22 is fixedly connected to the conductive post mounting surface 16. The socket body mounting surface 22 is fixedly connected to the socket body tail end 26 through multiple reinforcing connecting pieces 24.
[0030] The plug body 1 has a wire channel 12 inside. One end of the wire channel 12 is connected to the discharge socket 6, signal socket 7, and signal socket 8, and the other end of the wire channel 12 is connected to the external wire sleeve 13. The discharge wire passes through the external wire sleeve 13 and the wire channel 12 in sequence and is connected to the discharge socket 6. The signal wire passes through the external wire sleeve 13 and the wire channel 12 in sequence and is connected to the signal socket 7 and signal socket 8.
[0031] Please refer to the actual usage. Figure 6 When the plug protrusion 2 of the plug body 1 approaches the socket body 25, the magnetic force generated by the interaction between the annular magnet 14 inside the plug body 1 and the annular magnet 2 inside the socket body 25 causes the plug protrusion 2 of the plug body 1 to be drawn into the cylindrical cavity of the mounting surface 22 of the socket body. This allows the discharge post 17 to be inserted into the discharge socket 6, the signal plug 18 to be inserted into the signal socket 7, and the signal plug 19 to be inserted into the signal socket 8. Because of the presence of the matching limiting slot 9, the matching limiting slot 10, the matching limiting head 20, and the matching limiting head 21, there is no need to worry about incorrect alignment of the plug body 1 causing incorrect connection and resulting in a short circuit.
[0032] When it is necessary to unplug the plug, simply pull the outer wire sleeve 13. Under the action of force, the plug protrusion 4 of the plug body 1 becomes a fulcrum, thereby converting the pulling force into a lever force through the plug protrusion 4 of the plug body 1. Under the action of the lever force, the plug body 1 can be easily removed.
[0033] The above description is merely a preferred embodiment of this utility model; however, the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be included within the protection scope of this utility model.
