Detailed Implementation

[0021] The specific implementation method is described below with reference to the accompanying drawings.

[0022] Example

[0023] like Figures 1 to 6As shown, this embodiment mainly discloses a battery converter tube, including a tube body 1. The tube body 1 has a cavity for accommodating several batteries. A positive electrode plate 2 is snapped into one axial end of the tube body 1, and a negative electrode plate 3 is snapped into the other axial end of the tube body 1. Both ends of the several batteries abut against the positive electrode plate 2 and the negative electrode plate 3 respectively to achieve parallel connection. Both the positive electrode plate 2 and the negative electrode plate 3 include an inner connecting piece 41 and an outer connecting piece 42. One side of the outer connecting piece 42 is connected to the inner connecting piece 41 through a bent guide piece 43, and the other side of the outer connecting piece 42 has a bent portion 44 that snaps into the end of the tube body 1. Specifically, the side wall of the tube body 1 has an opening to facilitate the efficient and centralized installation of several batteries, which helps with battery management and replacement. By attaching positive electrode 2 and negative electrode 3 to both ends of the cylinder 1 respectively, the positive electrode 2 and negative electrode 3 are divided into inner connecting piece 41 and outer connecting piece 42. Several batteries are connected in parallel between the inner connecting pieces 41, and the battery charge is conducted to the exposed outer connecting piece 42 through the bent conductor 43. The operation is simple and convenient, realizes the battery conversion, and enhances the reliability and stability of the battery connection.

[0024] Furthermore, in specific implementation, such as Figure 1 , Figure 2 As shown, in this embodiment of the invention, a groove 11 for limiting the outer connecting piece 42 is provided on the outer side of the end of the cylindrical body 1, and a slot 12 for engaging the inner connecting piece 41 is provided on the inner side wall of the end of the cylindrical body 1. Specifically, the groove 11 is a circular groove that matches the outer connecting piece 42, and avoidance openings are provided on both sides to avoid the bending guide piece 43 and the bending part 44, effectively limiting the position of the outer connecting piece 42 and the inner connecting piece 41, ensuring that they do not shift during use, thereby improving the safety and stability of the product.

[0025] Furthermore, in specific implementation, such as Figure 2 , Figure 4 , Figure 5 As shown, the inner connector 41 provided in this embodiment of the present invention has a guide groove 410, and a support column 13 is provided inside the cylinder 1 along the central axis. The two ends of the support column 13 are respectively limited and engaged with the guide groove 410. Specifically, the guide groove 410 is a strip-shaped groove. In the initial state, the bent portion 44 of the outer connector 42 is flush with the outer connector 42, and the cross-sections of the positive electrode 2 and the negative electrode 3 are horizontally U-shaped. During installation, the positive electrode 2 and the negative electrode 3 are first inserted into the end of the cylinder 1 respectively. The inner connector 41 slides along the slot 12 on both sides, and its guide groove 410 moves relative to the support column 13 until the support column 13 abuts the end of the guide groove 410. After installation, the bent portion 44 is bent to connect the positive electrode 2 and the negative electrode 3 to the cylinder 1. This further enhances the fixation of the positive electrode 2 and the negative electrode 3, prevents the battery from loosening inside the cylinder 1 due to vibration or other reasons, and improves the safety of use.

[0026] Furthermore, in specific implementation, such as Figures 1-3, Figure 6 As shown, the external connector 42 provided in this embodiment of the present invention has a positioning hole 420, and the outer side of the end of the cylinder 1 has a positioning protrusion 14 that cooperates with the positioning hole 420 for positioning and installing the external connector 42. This allows for more precise positioning of the external connector 42, avoids poor contact caused by improper installation, and improves assembly efficiency and reliability.

[0027] Furthermore, in specific implementation, such as Figure 3 , Figure 6 As shown, the outer contact plate 42 of the positive electrode 2 provided in this embodiment of the invention is marked with a positive electrode mark, and the outer contact plate 42 of the negative electrode 3 is marked with a negative electrode mark. This facilitates users in identifying the polarity of the battery during use and reduces the risk of damage caused by connecting the battery in the wrong direction.

[0028] Furthermore, in specific implementation, such as Figure 4 , Figure 5 As shown, the inner contact plate 41 of the positive electrode 2 provided in this embodiment of the present invention is provided with a protrusion 411 that contacts the positive electrode of the battery, and the inner contact plate 41 of the negative electrode 3 is provided with a spring 412 that contacts the negative electrode of the battery. Through the tight contact between the spring 412 and the protrusion 411, the battery can be stably installed inside the cylinder 1, ensuring good contact between the battery and the positive electrode 2 and the negative electrode 3, forming a stable current path, reducing contact resistance, and improving energy transfer efficiency.

[0029] Furthermore, in a specific implementation, four batteries are evenly arranged within the aforementioned receiving cavity provided in this embodiment of the utility model. The batteries are size 5 (AA) batteries, and the outer diameter and height of the cylinder 1 are the same as those of a size 1 battery. Specifically, in the prior art, the height of a size 1 battery is 59.0±0.5mm, and its diameter is 32.3±0.2mm. The height of a size 5 flat-top battery is 48.0±0.5mm, and its diameter is 14.1±0.2mm. It should be noted that the voltage of a size 1 battery is typically 1.5V, and the voltage of a size 5 battery is also typically 1.5V. That is, when size 5 batteries are connected in parallel, the voltage remains unchanged, increasing the overall current output and realizing the conversion from size 5 to size 1 batteries, thus improving compatibility and flexibility.

[0030] Furthermore, in specific implementation, such as Figure 1 As shown, in this embodiment of the invention, the side wall of the cylindrical body 1 is marked with a positive electrode mark at one end of the positive electrode plate 2, and the side wall of the cylindrical body 1 is marked with a negative electrode mark at one end of the negative electrode plate 3. This further facilitates users in checking the battery during installation, avoiding damage or short circuit risks caused by operational errors, and improving the safety and convenience of use.
