[0002] With the wide application of portable electronic devices and energy storage systems, the connection structure of battery packs needs to simultaneously meet the high reliability of electrical connection, the stability of mechanical structure, and the convenience of operation. Traditional battery connection methods mainly rely on single mechanical buckles or magnetic attraction connections, which have obvious defects: 1. Mechanical buckle connection: Although it can provide a certain structural stability, it is prone to poor contact due to wear during long-term use, and precise alignment is required during assembly, making the operation inconvenient.

[0003] 2. Magnetic attraction connection: Although it is convenient for quick plugging and unplugging, the magnetic attraction force is limited, and it is easy to loosen under vibration or external force, resulting in an interruption of electrical connection..

[0004] In the prior art, some solutions attempt to combine mechanical buckles with magnetic structures, but do not provide an independent electrode plugging structure, resulting in insufficient reliability of electrical connection; the mechanical buckles of traditional structures usually require complex operations and are difficult to meet the requirements of high-efficiency production and quick battery replacement by users.

[0005] Therefore, there is an urgent need for a dual connection structure for batteries that can simultaneously improve mechanical stability, electrical connection reliability, and operation convenience. Summary of the Invention

[0023] Regarding the foregoing and other technical contents, features and effects of the present invention, they will be clearly presented in the following detailed description in conjunction with the Figures 1-5 embodiments. The structural contents mentioned in the following embodiments are all with reference to the drawings of the specification.

[0024] The following will describe each exemplary embodiment of the present invention with reference to the drawings.

[0025] Embodiment 1, a dual connection structure for a battery, comprising multiple groups of batteries 1, and adjacent batteries 1 are doubly connected through a magnetic attraction component 2, a mechanical clamping component 3 and an electrode plugging structure 4, and the structure is as follows: Battery body structure: Each group of batteries 1 is composed of an upper housing 11 and a lower housing 12 that are buckled with each other.

[0026] The upper housing 11 is provided with a battery connection female head 13, and the lower housing 12 is provided with a battery connection male head 14 that cooperates with the battery connection female head 13. Both are made of anti-oxidation metal materials, and the inner wall of the female head is provided with elastic conductive sheets to ensure reliable conductivity.

[0027] Magnetic attraction component 2: A first magnet sheet 21 is embedded at the top of the upper housing 11, and a second magnet sheet 22 is embedded at the corresponding position at the bottom of the lower housing 12. The first magnet sheet 21 and the second magnet sheet 22 are permanent magnets, and the opposite faces have opposite magnetic poles. The battery is initially positioned by magnetic attraction.

[0028] Mechanical clamping component 3: Guide member 31: A limit frame 311 is fixed inside the battery 1, and a limit block 312 is slidably arranged inside the limit frame. The limit block is fixedly connected to the clamping block 32.

[0029] A connecting member 313 is hinged at the center of the limit block 312. The connecting member 313 is provided with a first limit block 316, and the limit block 312 is provided with a second limit block 317, which cooperate with the first limit groove 314 and the second limit groove 315 on the limit frame. The first limit groove 314 is an inverted L groove, and the second limit groove 315 is a right-side-up L groove. Among them, the bottoms of the first limit groove 314 and the second limit groove 315 are both open. The first limit block 316 and the second limit block 317 are both cylindrical. The first limit block 316 and the second limit block 317 are slidably matched in the first limit groove 314 and the second limit groove 315; There is a spring 318 between one end of the connecting member 313 and the inner side wall of the lower housing 12, and the other end extends to the outside of the battery to form a handle 319.

[0030] Clamping cooperation: The clamping blocks 32 of adjacent batteries 1 and the clamping grooves 33 are correspondingly arranged. In the first step, by pressing the handle 319, the connecting member 313 overcomes the elastic force of the spring 318. Under the action of the first limit groove 314 and the second limit groove 315, the connecting member 313 and the limit block 312 are driven to slide in the limit frame 311. At this time, the hook part of the clamping block 32 of the adjacent battery 1 disengages from the clamping groove 33. In the second step, sliding along the height direction of the first limit groove 314 or the second limit groove 315, the connecting member 313 rotates along the hinge point of the limit block 312 against the elastic force of the spring 318, lifting the limit block 312 upward, so that the clamping block 32 of the adjacent battery 1 completely disengages from the clamping groove 33, realizing the quick separation and combination of the battery pack; Electrode plugging structure 4: Electrode pins 41 and electrode sockets 42 are respectively arranged on the opposite side surfaces of adjacent batteries 1, and the surfaces are plated with a metal layer to reduce the contact resistance and ensure the conductivity.

[0031] Technical effect: Dual connection stability: The magnetic attraction component provides pre-positioning, the mechanical clamping realizes rigid fixation, and the electrode plugging ensures reliable conductivity. The three cooperate to improve the overall connection strength of the battery pack.

[0032] Convenient disassembly and assembly: By operating the mechanical clamping components through the handle, the battery pack can be quickly separated or assembled, improving the maintenance efficiency.

[0033] Anti-oxidation design: The male and female battery connectors are made of anti-oxidation materials, extending the service life.

[0034] Embodiment 2: Based on Embodiment 1, the battery connection structure is further optimized in this embodiment by adding a positioning component 5, which is specifically as follows: Positioning component 5: A positioning groove 51 is opened at the top of the upper housing 11, and the first magnet sheet 21 is embedded in the groove.

[0035] A positioning block 52 protrudes from the top of the lower housing 12 and is inserted and matched with the positioning groove 51.

[0036] An elastic sealing gasket is provided on the wall of the positioning groove 51, and a corresponding sealing groove is provided on the outer side wall of the positioning block 52 to form a waterproof sealing structure.

[0037] Other improvements: The thickness of the metal layer on the surfaces of the electrode pins 41 and electrode sockets 42 is increased to further improve the electrical conductivity and corrosion resistance.

[0038] Technical effects: Precise positioning: The positioning component ensures the precise alignment of the magnetic poles, electrodes, and clamping structures of adjacent batteries 1, avoiding poor contact or clamping failure caused by misalignment.

[0039] Waterproof sealing: The elastic sealing gasket cooperates with the sealing groove to prevent liquid from entering the battery connection, improving the reliability of the battery pack in a humid environment.

[0040] Structure strengthening: The mechanical cooperation between the positioning block and the positioning groove enhances the impact resistance of the battery pack and reduces the connection looseness caused by vibration.

[0041] Summary of the implementation method: The present invention realizes the stable connection and convenient maintenance of the battery pack through a triple design of magnetic attraction, mechanical clamping, and electrode insertion. Embodiment 1 provides the basic structure, and Embodiment 2 further improves the performance through the positioning component and sealing design. Each embodiment can be implemented independently or combined to meet the requirements of different application scenarios.

[0042] The above description is only for the purpose of illustrating the present invention. It should be understood that the present invention is not limited to the above embodiments, and various equivalent forms that conform to the idea of the present invention are within the protection scope of the present invention.
