Replaceable battery products often use spring clips or screws for fixing, making replacement cumbersome and lacking support for vertically stacking multiple batteries for charging. They also lack emergency compatibility with dry cell batteries. Furthermore, traditional clips are prone to loosening under vibration, resulting in insufficient reliability. Therefore, we provide a detachable, modular clip-on power bank. Utility Model Content

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Existing power banks suffer from issues such as limited capacity expansion, cumbersome replacement, lack of support for multi-battery stacking charging, inadequate emergency compatibility with dry cell batteries, and easy loosening of traditional snap-fit ​​fasteners. This embodiment provides a detachable, modular snap-fit ​​power bank that allows for capacity expansion as needed, quick assembly and disassembly, support for vertical stacking of multiple batteries, dry cell battery emergency compatibility, enhanced snap-fit ​​structure stability under vibration, and improved reliability and flexibility. Please refer to... Figure 1 - Figure 3 The detachable modular snap-on power bank includes a battery module 1, on which an assembly mechanism 2 is provided for stacking multiple battery modules together. The assembly mechanism 2 can stack multiple battery modules 1 together and connect them through snap-on and magnetic coupling to ensure a stable stack that is not easily loosened in a vibration environment. It also supports hybrid power supply to expand capacity and improve the device's versatility, stability, and flexibility of use.

[0019] Most existing power banks have a single-piece casing, which cannot expand the capacity; replaceable battery products are often fixed with spring clips or screws, which is troublesome to replace, do not support vertical stacking of multiple batteries for charging, lack emergency compatibility with dry batteries, and traditional clips are prone to loosening in vibrating environments. In order to solve the above problems...

[0020] Assembly mechanism 2 includes multiple sets of guide plates 21 installed on one side of battery module 1. The guide plates 21 are made of nickel-plated copper alloy, which has good conductivity and corrosion resistance, ensuring the stability and durability of current transmission. The guide plates 21 on the top of battery module 1 correspond one-to-one with the guide plates 21 on the bottom, ensuring precise contact between the upper and lower guide plates 21 when multiple battery modules 1 are stacked, forming a stable conductive path and realizing effective power transmission after the multiple modules are stacked. This provides a basic guarantee for power supply after capacity expansion. Trapezoidal slots 22 are opened on both sides of battery module 1. The value of the bottom is smaller than that of the top, forming a structure that is narrower at the top and wider at the bottom. This facilitates quick alignment and embedding when multiple battery modules 1 are stacked, improving assembly efficiency. Furthermore, the depth of the trapezoidal slot 22 is the same as that of its top, providing sufficient positioning depth for module stacking to ensure connection stability while avoiding difficulties in disassembly and assembly due to excessive depth. This balances precise structural positioning with ease of operation. The trapezoidal slot 22 contains multiple sets of N35 neodymium magnets 23 and steel ball spring locking pins 24 distributed between every two sets of N35 neodymium magnets 23. The N35 neodymium magnets 23 are symmetrically distributed inside the trapezoidal slot 22. The symmetrical distribution ensures that the battery modules 1 are subjected to uniform force in all directions when stacked. The resulting attraction keeps the upper and lower battery modules 1 tightly fitted, maintaining relative positional stability even under vibration, preventing loosening or displacement. Furthermore, the N35 neodymium magnets 23 and the ball spring locking pins 24 form a snap-fit-magnetic composite connection. After the battery modules 1 are stacked in place, the stainless steel balls of the ball spring locking pins 24 pop out and lock into their corresponding positions, forming a mechanical lock. This, combined with the magnetic force of the N35 neodymium magnets 23, greatly enhances the stability of the connection between the modules, ensuring reliable operation of the power bank in various usage scenarios. The ball spring locking pin 24 consists of a stainless steel ball, a return spring, and a locking pin housing. The ball spring locking pin 24 is embedded inside the trapezoidal slot 22. When multiple battery modules 1 are stacked, the stainless steel ball is squeezed and retracts into the locking pin housing. After the modules are aligned, the return spring pushes the ball out and locks it into the corresponding module's slot, forming a mechanical lock. This, together with the N35 neodymium magnet 23, forms a snap-on-magnetic composite connection, further enhancing the stability of the connection between modules. It effectively prevents loosening in a vibration environment and facilitates quick assembly and disassembly, ensuring the reliability and convenience of stacked power banks.

[0021] When multiple battery modules 1 are stacked, the trapezoidal slots 22 on both sides interlock, and the wear-resistant coating on the inner wall ensures the durability of the structure. The N35 neodymium magnets 23 in the trapezoidal slot 22 below the battery module 1 and the N35 neodymium magnets 23 in the trapezoidal slot 22 above attract each other, and the magnetic force is used to achieve the initial connection. The symmetrically distributed N35 neodymium magnets 23 ensure uniform force. At the same time, the stainless steel balls in the ball spring locking pins 24 are squeezed and compressed into the locking pin shell. After the modules are aligned, the return spring pushes the steel balls to pop out and lock into the corresponding module's slot, forming a mechanical lock. This forms a snap-on-magnetic composite connection with the N35 neodymium magnets 23, which enhances stability. The nickel-plated copper alloy guide plates 21 on one side of the battery module 1 form a stable conductive path after stacking because the top and bottom positions correspond one-to-one, realizing power transmission.
