[0094] In this embodiment, preferably, Figure 1 and Fig.10 As shown, the outer wall of the second limiting side portion 13 is formed with a mounting groove 133 passing through the top thereof, the inner wall of the first limiting side portion 12 is formed with an avoidance opening 134 passing through the top thereof, and the avoidance opening 134 is communicated with the mounting groove 133, the positioning portion 31 is installed in the mounting groove 133, and part of the structure of the clamping portion 32 extends into the avoidance opening 134.

[0095] According to the structure described above, the bottom wall of the installation groove 133 can support the positioning portion 31 to a certain extent, making the positioning portion 31 more stable, and the avoidance opening 134 connected to the installation groove 133 plays a role in avoiding the clamping portion 32.

[0096] In this embodiment, preferably, Figure 2 and Fig.14 As shown, one of the limiting member 2 and the supporting member 1 is formed with a positioning protrusion 22 , and one of the limiting member 2 and the supporting member 1 is formed with a positioning groove 1111 , and the positioning protrusion 22 is inserted into the positioning groove 1111 .

[0097] According to the structure described above, it can be known that the positioning protrusion 22 cooperates with the positioning groove 1111 to achieve the function of assembling and positioning the limiting member 2 and the supporting member 1.

[0098] In this embodiment, preferably, Figure 2 and Fig.14 As shown, the limiting member 2 is a flat plate structure, and its bottom is in the shape of two steps. Correspondingly, the top of the supporting member 1 is formed with three matching steps to achieve stable assembly of the two.

[0100] In this embodiment, preferably, Figure 1 As shown, the angle between the inclined support surface 113 and the horizontal reference surface 114 is 15-30°. If the angle is too large, it will not prevent tipping and will be inconvenient to manufacture. If the angle is too large, the outer bracket 8 of the battery pack and the battery cell 9 will tip toward one side of the limiting member 2 during assembly.

[0101] In this embodiment, preferably, Fig.14As shown, the limiting member 2 and the supporting member 1 are detachably connected via a fifth fastening member such as a screw or a bolt (the figure only shows the fifth mounting hole 23 for mounting the second fastening member, without showing the fifth fastening member). This is a detachable connection method, which is convenient for later disassembly, maintenance or replacement. Of course, the connection method between the limiting member 2 and the supporting member 1 is not limited to this, and other connection methods may also be used. For example, the limiting member 2 and the supporting member 1 may also be connected by snapping, gluing or welding.

[0102] In this embodiment, preferably, Figure 1 As shown, the limiting member 2 is arranged at one end of the supporting member 1 along its length direction, which is convenient for assembly and fully utilizes the length direction of the limiting member 2, thereby helping to reduce material costs.
