[0018] The technical solution of this application will be further described below with reference to specific embodiments and accompanying drawings.

[0019] Please refer to the following: Figure 1 , Figure 2 and Figure 3In a first aspect, this utility model provides an aluminum battery 1, comprising two plates 11, a first insertion portion 12, and a second insertion portion 13. Each plate 11 has a connecting end 111 and a working end 112 facing away from each other, the two connecting ends 111 being connected to each other. Each plate 11 has a first surface 113 and a second surface 114 facing away from each other, the first surfaces 113 of the two plates 11 having the same orientation. The first insertion portion 12 is connected to one of the working ends 112, and the second insertion portion 13 is connected to the other working end 112. The first insertion portion 12 and the second insertion portion 13 are respectively connected to the first surfaces 113 of the two plates 11, and are configured to be inserted into the insertion holes 212 of the terminals 211 of two batteries 21.

[0020] In this embodiment, a first insertion part 12 and a second insertion part 13 are respectively provided on the two working ends 112 of the aluminum bar 1. The first insertion part 12 is used to be directly and detachably inserted into the insertion hole 212 of the terminal post 211 of one battery 21, and the second insertion part 13 is used to be directly and detachably inserted into the insertion hole 212 of the terminal post 211 of another battery 21, thereby connecting the two batteries 21 in series to form a battery group 21.

[0021] When the battery 21 needs maintenance or replacement, the first connector 12 is removed from the connector hole 212 of the corresponding battery 21 post 211, and the second connector 13 is removed from the connector hole 212 of the corresponding battery 21 post 211, thereby directly removing the aluminum bar 1 from the battery 21 group 2. After the battery 21 is maintained or replaced, the first connector 12 and the second connector 13 are respectively inserted into the connector holes 212 of the two battery 21 posts 211, thereby directly connecting the two batteries 21 in series again. Alternatively, when only maintenance or replacement of the battery 21 corresponding to the first connector 12 is required, the first connector 12 can be removed from the connector hole 212 of the corresponding battery 21's terminal 211. After maintenance or replacement of the battery 21, the first connector 12 can be reinserted into the connector hole 212 of the corresponding battery 21's terminal 211. During this process, the second connector 13 can remain inserted into the connector hole 212 of the corresponding battery 21's terminal 211. Alternatively, when only maintenance or replacement of the battery 21 corresponding to the second connector 13 is required, the second connector 13 can be removed from the connector hole 212 of the corresponding battery 21's terminal 211. After maintenance or replacement of the battery 21, the second connector 13 can be reinserted into the connector hole 212 of the corresponding battery 21's terminal 211. During this process, the first connector 12 can remain inserted into the connector hole 212 of the corresponding battery 21's terminal 211.

[0022] In this embodiment, by providing a first insertion part 12 and a second insertion part 13 for insertion holes 212 that can be respectively inserted into the terminals 211 of the two batteries 21, the aluminum bar 1 can be detachably connected to the battery 21. Compared with the prior art of welding the aluminum bar 1 to the terminals 211 of the battery 21, this application allows the aluminum bar 1 to be directly removed from the battery 21 when the battery 21 needs maintenance or replacement, and the aluminum bar 1 can be directly installed on the battery 21 after replacement, eliminating welding and other steps, shortening maintenance time, and improving maintenance efficiency.

[0023] Please see Figure 3 In some embodiments, the first plug-in portion 12 includes a first plug-in post 121 and a second plug-in post 122, the first plug-in post 121 and the second plug-in post 122 extend in the same direction, and the first plug-in post 121 and the second plug-in post 122 are both connected to the first surface 113 of one of the plates 11. In this embodiment, both the first plug post 121 and the second plug post 122 are columnar structures. The plug hole 212 of the battery 21 terminal post 211 includes a first plug hole 212 and a second plug hole 212. When the first plug part 12 is plugged into the plug hole 212 of the battery 21 terminal post 211, the first plug post 121 is plugged into the first plug hole 212, and the second plug post 122 is plugged into the second plug hole 212.

[0024] The length of the first plug-in post 121 can be approximately the same as the length of the second plug-in post 122, or they can be different; this is not limited here. Similarly, the diameter of the first plug-in post 121 can be approximately the same as the diameter of the second plug-in post 122, or they can be different; this is not limited here.

[0025] By setting the first plug post 121 and the second plug post 122, the limiting and positioning effect of the aluminum bar 1 can be strengthened, and the stability of the connection between the battery 21 and the aluminum bar 1 can be enhanced.

[0026] In some embodiments, the first plug post 121 and the second plug post 122 are spaced apart.

[0027] In this embodiment, the first plug-in post 121 and the second plug-in post 122 are spaced apart, which makes it easy to distinguish between the first plug-in post 121 and the second plug-in post 122 and improves the installation efficiency.

[0028] Please see Figure 3 In some embodiments, the number of second plug posts 122 is at least two, and at least two second plug posts 122 are arranged around the first plug post 121.

[0029] In this embodiment, at least two second plug posts 122 are arranged around the first plug post 121, which can further and quickly distinguish the first plug post 121 and the second plug post 122, and at the same time can further enhance the stability of the connection between the aluminum bar 1 and the battery 21.

[0030] For example, there is one first plug post 121 and eight second plug posts 122, which are evenly arranged around one first plug post 121.

[0031] Please see Figure 3 In some embodiments, the second plug-in portion 13 includes a third plug-in post 131 and a fourth plug-in post 132. The third plug-in post 131 and the fourth plug-in post 132 extend in the same direction, and the first plug-in post 121 extends in the same direction as the third plug-in post 131. The third plug-in post 131 and the fourth plug-in post 132 are both connected to the first surface 113 of another plate 11.

[0032] In this embodiment, both the third plug post 131 and the fourth plug post 132 are columnar structures. The plug hole 212 of the battery 21 pole post 211 includes a third plug hole 212 and a fourth plug hole 212. When the second plug part 13 is plugged into the plug hole 212 of the battery 21 pole post 211, the third plug post 131 is plugged into the third plug hole 212, and the fourth plug post 132 is plugged into the fourth plug hole 212.

[0033] The length of the third connector 131 can be approximately the same as, or different from, the length of the fourth connector 132, and this is not limited here. Similarly, the diameter of the third connector 131 can be approximately the same as, or different from, the diameter of the fourth connector 132, and this is not limited here. Furthermore, the length and diameter of the third connector 131 can be approximately the same as, or different from, the length and diameter of the first connector 121, and this is not limited here; the length and diameter of the third connector 131 can be approximately the same as, or different from, the length and diameter of the second connector 122, and this is not limited here; the length and diameter of the fourth connector 132 can be approximately the same as, or different from, the length and diameter of the second connector 122, and this is not limited here.

[0034] By setting the third plug post 131 and the fourth plug post 132, the limiting and positioning effect of the aluminum bar 1 can be strengthened, and the stability of the connection between the aluminum bar 1 and the battery 21 can be enhanced.

[0035] In some embodiments, the third plug post 131 and the fourth plug post 132 are spaced apart. In this embodiment, the third plug-in post 131 and the fourth plug-in post 132 are spaced apart, which makes it easy to distinguish between the third plug-in post 131 and the fourth plug-in post 132 and improves the efficiency of installation.

[0036] Please see Figure 3 In some embodiments, the number of fourth plug posts 132 is at least two, and at least two fourth plug posts 132 are arranged around the third plug post 131. In this embodiment, at least two fourth plug posts 132 are arranged around the third plug post 131, which can further quickly distinguish between the third plug post 131 and the fourth plug post 132, and at the same time can further enhance the stability of the connection between the aluminum bar 1 and the battery 21.

[0037] For example, there is one third plug post 131 and eight fourth plug posts 132, with the eight fourth plug posts 132 evenly arranged around one third plug post 131.

[0038] Please see Figure 3 In some embodiments, the aluminum bar 1 further includes a transition section 14, which is connected between the connecting ends 111 of the two plates 11, and a through-hole fusion groove 141 is provided in the middle of the transition section 14. In this embodiment, a through-hole fuse groove 141 is provided in the middle of the transition section 14 to reduce the distance between the two ends of the fuse groove 141 and the two side edges of the transition section 14, so that it can play a protective role in cutting off the circuit when the battery 21 is overloaded.

[0039] For example, when the battery 21 is overloaded, the current through the aluminum bar 1 is too large. When the current passes through the transition section 14, the area between the end of the fuse groove 141 and the edge on the same side of the transition section 14 is too hot and melts due to the small distance between the two ends of the fuse groove 141 and the edge on the same side of the transition section 14, thereby achieving the effect of cutting off the circuit and playing a safety role.

[0040] In this embodiment, a through-hole fuse groove 141 is provided in the transition section 14 so that the aluminum bar 1 has a safety function, which can further improve the safety of the battery 21.

[0041] Please see Figure 3 In some embodiments, the transition portion 14 is arc-shaped, and the transition portion 14 protrudes from the second surface 114 in a direction away from the first surface 113.

[0042] Please refer to the following: Figure 1 and Figure 2Secondly, this utility model also provides a battery group 21, including the aluminum bar 1 as described above and at least two batteries 21. The terminals 211 of at least two batteries 21 are each provided with a insertion hole 212. A first insertion part 12 is inserted into the insertion hole 212 of one battery 21, and a second insertion part 13 is inserted into the insertion hole 212 of the other battery 21.

[0043] In this embodiment of the application, the battery group 21 includes two batteries 21. The top of the terminal post 211 of the two batteries 21 is provided with a plug hole 212. The first plug part 12 is plugged into the plug hole 212 of the terminal post 211 of one of the batteries 21, and the second plug part 13 is plugged into the plug hole 212 of the terminal post 211 of the other battery 21.

[0044] When the battery 21 of battery group 21 needs maintenance or replacement, the first plug part 12 is removed from the plug hole 212 of the corresponding battery 21 post 211, and the second plug part 13 is removed from the plug hole 212 of the corresponding battery 21 post 211, thereby directly removing the aluminum bar 1 from battery group 21. After the battery 21 is maintained or replaced, the first plug part 12 and the second plug part 13 are respectively inserted into the plug holes 212 of the two battery 21 posts 211, thereby directly connecting the two batteries 21 in series again. Alternatively, when only maintenance or replacement of the battery 21 corresponding to the first connector 12 is required, the first connector 12 can be removed from the connector hole 212 of the corresponding battery 21's terminal 211. After maintenance or replacement of the battery 21, the first connector 12 can be reinserted into the connector hole 212 of the corresponding battery 21's terminal 211. During this process, the second connector 13 can remain inserted into the connector hole 212 of the corresponding battery 21's terminal 211. Alternatively, when only maintenance or replacement of the battery 21 corresponding to the second connector 13 is required, the second connector 13 can be removed from the connector hole 212 of the corresponding battery 21's terminal 211. After maintenance or replacement of the battery 21, the second connector 13 can be reinserted into the connector hole 212 of the corresponding battery 21's terminal 211. During this process, the first connector 12 can remain inserted into the connector hole 212 of the corresponding battery 21's terminal 211.

[0045] In this embodiment, by providing a first insertion part 12 and a second insertion part 13 for insertion holes 212 that can be respectively inserted into the terminals 211 of the two batteries 21, the aluminum bar 1 can be detachably connected to the battery 21. Compared with the prior art of welding the aluminum bar 1 to the terminals 211 of the battery 21, this application allows the aluminum bar 1 to be directly removed from the battery 21 when the battery 21 needs maintenance or replacement, and the aluminum bar 1 can be directly installed on the battery 21 after replacement, eliminating welding and other steps, shortening maintenance time, and improving maintenance efficiency.
