[0027] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention 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 invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.
[0028] It should be noted that the terms "comprising" and "having" and any variations thereof in the specification, claims and accompanying drawings of this utility model are intended to cover non-exclusive inclusion. For example, a process, method, apparatus, product or device that includes a series of steps or units is not necessarily limited to those steps or units that are explicitly listed, but may include other steps or units that are not explicitly listed or that are inherent to such processes, methods, products or devices.
[0029] The following is in conjunction with the appendix Figures 1-5 This application will be described in further detail.
[0030] like Figures 1-5 As shown, a multifunctional battery adapter includes: a main body 1, which is T-shaped, and two horizontally opposite ends of the main body 1 are provided with a communication connection port 2, a battery positive connection port 3, and a battery negative connection port 4. The communication connection port 2, the battery positive connection port 3, and the battery negative connection port 4 on the same side are arranged in a triangle.
[0031] To facilitate connection and avoid tangling of wires, the two communication connection ports 2 are on the same straight line, the two battery positive connection ports 3 are on the same straight line, and the two battery negative connection ports 4 are on the same straight line.
[0032] The bottom of the main body 1 is provided with a plug-in integrated port 5 for connecting to the battery.
[0033] Based on the above structure, in use, the plug-in integrated port 5 is plugged into the battery's connection port to connect to the battery; the T-shaped main body 1, with a communication connection port 2, a battery positive connection port 3, and a battery negative connection port 4 at both ends, can accommodate multiple batteries connected in series (e.g., Figure 4 As shown), if the customer only has one set of batteries, they can choose any pair of terminals for connection, which is flexible and convenient. No wiring is required from the customer; it's plug-and-play. This application can be used for stacked batteries (such as...). Figure 3 (as shown) or wall-mounted battery (such as Figure 5 (As shown).
[0034] Furthermore, communication port 2 is an RJ45 waterproof interface, compatible with standard network cables, and adaptable to various application environments.
[0035] like Figure 1 and Figure 2 As shown, to prevent the device from coming loose during use or being accidentally pulled out, which could cause safety issues, an anti-theft fixing plate 6 is provided on one side of the bottom of the main body 1. The anti-theft fixing plate 6 has several bolt holes 61. After the plug-in integrated port 5 is plugged into the battery's connection port, the anti-theft fixing plate 6 is connected and fixed to the battery with screws to prevent it from coming loose. There are two bolt holes 61, and the two bolt holes 61 are located directly above the two sides of the main body 1. In this way, the main body 1 will not block the bolt holes 61, making it easy to tighten the screws.
[0036] A further optimization is that the plug-in integrated port 5 has a foolproof structure, specifically as follows: Figure 2 As shown, the two sides of the plug-in integrated port 5 are arranged in different shapes to provide a unique plug-in method.
[0037] Furthermore, the outer shell of the main body 1 is made of UV-resistant and flame-retardant materials.
[0038] In summary, when using, plug the integrated port 5 into the battery connection port to connect to the battery; the T-shaped main body 1, which is equipped with a communication connection port 2, a battery positive connection port 3 and a battery negative connection port 4 at both ends, can meet the needs of multiple batteries connected in series. If the customer only has one set of batteries, they can choose any pair of terminals to connect, which is flexible and convenient, and does not require the customer to connect wires. It is plug and play.
[0039] This application is simple and convenient to install, greatly saving installation time and labor, and improving installation efficiency; the error rate is greatly reduced; the T-shaped main body design is compact and lightweight, suitable for connecting multiple batteries in series, and the wiring is simple and beautiful; the RJ45 waterproof interface is compatible with standard network cables, plug and play; the plug-in integrated port 5 foolproof design prevents customers from connecting incorrectly; the anti-loosening design prevents it from falling off or being stolen; the shell material is UV resistant and flame retardant, ensuring high safety.
[0040] The above are merely preferred embodiments of this application, and the present invention is not limited to the above embodiments.
