[0032] like Figures 1 to 5 As shown, the battery pack of this embodiment includes a battery pack body 1, an adapter 2, a mounting assembly 3 and a blocking assembly 4; the adapter 2 can be connected to the battery pack body 1, and the installation is simple; the mounting assembly 3 includes a first mounting portion 31 and a second mounting portion 32, one of the battery pack body 1 and the adapter 2 is provided with the first mounting portion 31, and the other is provided with the second mounting portion 32, and the first mounting portion 31 and the second mounting portion 32 cooperate to realize the detachable connection between the battery pack body 1 and the adapter 2, which is simple to connect and convenient to disassemble; the blocking assembly 3 can prevent the connected battery pack body 1 from being separated from the adapter 2. The battery pack body 1 is shared, and when there is a customer's need, only the adapter 2 needs to be redesigned, and different adapters 2 are installed on the battery pack body 1 to form different battery packs to meet the use needs of different customers, which can improve the versatility of the battery pack, save the mold cost and shorten the development cycle when developing a new battery pack, and can reduce the cost of developing new products. In this embodiment, the battery pack body 1 and the adapter 2 are connected by the mounting assembly 3, which can improve the versatility of the battery pack, and the installation is simple and convenient.

[0033] Specifically, in this embodiment, the first mounting portion 31 is a guide rail extending in a first direction, and the second mounting portion 32 is a guide rail groove, and the guide rail is slidably connected to the guide rail groove.

In other embodiments, the first mounting portion 31 can also be a buckle, and the second mounting portion is a slot. One of the battery pack body 1 and the adapter 2 is provided with a buckle, and the other is provided with a slot. The buckle is inserted into the slot to connect the battery pack body 1 and the adapter 2; in some other embodiments, the first mounting portion 31 and the second mounting portion 32 can also be other connection structures, which are not specifically limited here.

[0034] In this embodiment, if Figure 1-Figure 3 As shown, along the first direction, a guide rail groove is provided on the battery pack body 1, and a guide rail is provided on the adapter 2. Along the first direction, the engagement distance between the guide rail and the guide rail groove is relatively long, which can increase the connection stability between the battery pack body 1 and the adapter 2. In other embodiments, the battery pack body 1 may be provided with a guide rail, and the adapter 2 may be provided with a guide rail groove, which is not specifically limited here.

[0035] It should be noted that, in some embodiments, the first direction is the length direction of the battery pack, and the second direction is the thickness direction of the battery pack.

[0036] Preferably, the battery pack body 1 is provided with two guide rail grooves, which are located at both ends of the battery pack body 1 along the width direction. Correspondingly, the adapter 2 is provided with two guide rails, which are respectively arranged in one-to-one correspondence with the two guide rail grooves. The two guide rail grooves and the two guide rails can ensure that the battery pack body 1 and the adapter 2 will not be offset or misaligned when they are slidably connected, ensuring a stable connection.

[0037] Furthermore, the blocking assembly 4 includes a blocking member 41 and a blocking portion 42. One of the battery pack body 1 and the adapter 2 is provided with the blocking member 41, and the other is provided with the blocking portion 42. In the blocking state, at least a portion of the blocking member 41 is placed in the blocking portion 42 to prevent the battery pack body 1 from being separated from the adapter 2. When the guide rail slides to the end of the guide rail groove, the adapter 2 can be clamped to the battery pack body 1 through the blocking member 41, so that the battery pack body 1 and the adapter 2 are locked with each other, so that the battery pack body 1 and the adapter 2 are solidified into a whole, thereby realizing the complete function of a battery pack.

[0038] In this embodiment, a blocking member 41 is provided on the battery pack body 1, and a blocking portion 42 is provided on the adapter 2; in other embodiments, a blocking portion 42 may be provided on the battery pack body 1, and a blocking member 41 may be provided on the adapter 2, which is not specifically limited here.

[0039] Furthermore, if Figure 4As shown, the blocking assembly 4 also includes a second blocking member 43, at least part of which is disposed through the blocking portion 42, and the second blocking member 43 abuts against the blocking member 41, so that the blocking member 41 moves along a second direction, and the second direction is perpendicular to the first direction. After the adapter 2 is slidably connected to the battery pack body 1 along the guide rail installation direction, when the battery pack body 1 needs to be separated from the adapter 2, the second blocking member 43 is pressed, and the adapter 2 is pushed in the direction opposite to the installation direction, and the adapter 2 can slide out along the guide rail groove direction, thereby separating the battery pack body 1 from the adapter 2, and realizing rapid disassembly and replacement of the battery pack, and the operation method is simple.

[0040] Preferably, the blocking member 41 is also provided with a guide slope 411, which is inclined downward in the first direction, and drives the blocking member 41 to move in the second direction when the adapter 2 moves in the first direction.

In this embodiment, the first connection part 11 is a plug-in clip, and the second connection part 21 is an insert, and the insert is inserted into the plug-in clip. In this embodiment, when the adapter 2 is slidably installed on the battery pack body 1, the slide rail 31 moves with the slide rail groove 32 so that the insert is inserted into the plug-in clip, thereby realizing the installation of the entire battery pack.

[0044] Preferably, the plug-in clip has two symmetrically arranged snap-fit ​​springs, and each snap-fit ​​spring has at least one snap-fit ​​point. The plug-in is inserted in the middle position of the two snap-fit ​​springs, so that the forces on both sides of the plug-in are balanced when the plug-in is inserted into the plug-in clip, thereby ensuring that the first connecting part 11 and the second connecting part 21 are firmly connected.

[0045] Preferably, the first connection portion 11 includes at least two plug-in clips, so as to adapt to the number of plug-in clips on different adapters 2, and the versatility is stronger. In this embodiment, the first connection portion 11 includes three plug-in clips, and the second connection portion 21 includes three plug-in clips, and the three plug-in clips are plugged into the three plug-in clips one by one. In other embodiments, the number of appropriate plug-in clips can be selected according to the use requirements, and is not specifically limited here.

[0046] The adapter 2 in this embodiment includes an upper shell 20 and an upper shell cover 22, the upper shell cover 22 is covered on the upper shell 20, the plug-in portion of the second connection portion 21 is placed in the upper shell 20, a second avoidance hole 2201 is provided on the upper shell cover 22, the plug-in portion of the second connection portion 21 passes through the second avoidance hole 2201, and the plug-in passing through the second avoidance hole 2201 protrudes from the upper shell cover 22 and is electrically connected to the first connection portion 11.

[0047] Furthermore, the battery pack body 1 further includes a shell 12 and a cover plate 13, the cover plate 13 is covered on the shell 12, the first connection portion 11 is arranged in the shell 12, a first avoidance hole 1301 is provided on the cover plate 13, and the second connection portion 21 passes through the first avoidance hole 1301 and is electrically connected to the first connection portion 11. The first connection portion 11 is hidden in the shell 12, which can prevent the first connection portion 11 from short circuiting, thereby improving the safety and service life of the battery pack body 1.

[0048] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention.
