[0022] 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.

[0023] Please see Figure 1-4 This utility model discloses a charger-compatible contact structure, including a charger body 1. The charger body 1 includes a base 11 and a top cover 12. The base 11 includes a battery compartment 111 with a plurality of charging slots 112 inside. The top cover 12 includes a light panel 122 with a plurality of independent contact metals 123 integrated at the bottom. The plurality of independent contact metals 123 correspond one-to-one with the plurality of charging slots 112.

[0024] Specifically, the bottom of the inner cover 124 and the top of the battery compartment 111 are provided with matching buckles 13, and the upper cover 12 and the base 11 are movably connected by the buckles 13.

[0025] In this embodiment, the buckle 13 is a common rotary buckle connection method on the market, which is fastened by rotating in the forward direction and separated by rotating in the reverse direction. This design makes the connection and separation of the base 11 and the top cover 12 simpler. The decorative part 115 and the outer shell 121 are both provided with anti-slip ripples, making it easier to assemble and disassemble the top cover 12 and the base 11.

[0026] Specifically, the bottom edge of the independent contact metal 123 is chamfered, the diameter of the independent contact metal 123 is greater than half the diameter of the charging compartment 112, and the independent contact metal 123 and its corresponding charging compartment 112 are coaxially arranged.

[0027] In this embodiment, the diameter of the independent contact metal 123 is larger than half the diameter of the charging compartment 112, increasing the area of ​​the independent contact metal 123. This allows the positive terminals of AA or AAA batteries inside the charging compartment 112 to effectively contact it. Furthermore, the design of several independent contact metals 123 and independent springs 114 enables several charging compartments 112 to charge AA or AAA batteries simultaneously, resulting in higher compatibility and broader application prospects. The chamfered design around the bottom of the independent contact metal 123 makes the contact between the battery positive terminal and the independent contact metal 123 smoother and reduces jamming.

[0028] Specifically, a motherboard 113 is embedded at the bottom of the battery compartment 111, and a spring 114 is provided at the top of the motherboard 113, which corresponds to and is sleeved with a number of charging compartments 112.

[0029] In this embodiment, the spring 114 can not only conduct electricity, but also lift the battery so that the positive terminal of the battery can make effective contact with the independent contact metal 123. It is suitable for use with batteries of different sizes such as AA or AAA specifications and has high versatility. The main board 113 also integrates a power supply interface for connecting the power cord.

[0030] Specifically, the upper cover 12 also includes an upper shell 121, the lamp panel 122 is disposed inside the upper shell 121, the upper shell 121 is also provided with an inner cover 124 located at the bottom of the lamp panel 122, and the top of the lamp panel 122 is provided with lamp beads corresponding to a number of independent contact metals 123.

[0031] In this embodiment, several LED beads correspond to several independent contact metal 123, which can display the charging status of the battery inside each charging compartment 112, making it more convenient to use.

[0032] Specifically, the inner cover 124 has a through hole 125 that is fitted into the independent contact metal 123.

[0033] In this embodiment, since the top cover 12 and the base 11 are connected by a rotating fastener, after the battery is placed inside the charging compartment 112, the top cover 12 needs to be used to press the battery down and then rotated. This causes the positive terminal of the battery and the independent contact metal 123 to have a process of misalignment, rotation, contact, and alignment. The through hole 125 can limit the independent contact metal 123, ensuring the stability of the independent contact metal 123 when it is contacted, making it less likely for the lamp board 122 to desolder or fall off, thus improving the product's service life. The battery to be charged is placed inside the charging compartment 112, the top cover 12 and the base 11 are closed, and the battery can be charged by connecting the power supply interface and the mains power through the power cord.

[0034] Specifically, the battery compartment 111 is fitted with a decorative piece 115, the bottom of the battery compartment 111 is provided with a bottom cover 116, and the top of the upper shell 121 is provided with a PC lens 126.

[0035] In this embodiment, the upper shell 121 has holes corresponding to the LED beads inside. After the LED beads are lit, the light is projected onto the PC lens 126 through the holes for easy observation by the user. The inner cover 124 and the lamp board 122 are fixed inside the upper shell 121 with screws. The bottom cover 116 and the main board 113 are fixed to the bottom of the battery compartment 111 with screws. The bottom of the bottom cover 116 is also provided with a silicone pad to cover the screw holes, which maintains the appearance of the product while also providing a non-slip effect and making it more stable to place.

[0036] Specifically, the battery compartment 111 is provided with a conductive terminal 117 that is electrically connected to the main board 113, and the bottom of the lamp board 122 is integrated with a conductive terminal 127, which is electrically connected to the conductive terminal 117.

[0037] In this embodiment, the second conductive terminal 127 is a spring pin type. When the upper cover 12 is rotated and snapped into place with the base 11, the second conductive terminal 127 is aligned with the first conductive terminal 117. The second conductive terminal 127 continuously contacts the first conductive terminal 117 through its elasticity, thereby achieving stable power supply. The main board 113 and the lamp board 122 are electrically connected through the first conductive terminal 117 and the second conductive terminal 127.

[0038] In summary, this charger features a compatible contact structure with a large area of ​​independent metal contacts 123, ensuring stable contact between the positive terminals of AA or AAA batteries of different sizes. This prevents charging failures caused by insufficient contact area. Each charging compartment 112 has an independent spring 114 at its bottom, which uses elasticity to lift the battery, ensuring that the positive terminals of batteries of different lengths can fit tightly against the top independent metal contacts 123. This adapts to the differences in AA or AAA battery specifications. Furthermore, the multiple independent metal contacts 123 support mixed charging of multiple battery specifications, resulting in high compatibility, long service life, and economic efficiency, thus possessing broad application prospects.

[0039] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
