[0062] Please refer to Figure 3 The interval distance between the toy ring 40 and the connecting piece 20 in the radial direction of the bearing 30 is D1, which satisfies 0.5mm≤D1≤1mm; the interval distance between the toy ring 40 and the shell 10 in the axial direction of the bearing 30 is D2, which satisfies 0.5mm≤D2≤1mm; the interval distance between the outer peripheral surface of the outer ring 31 and the shell 10 in the radial direction of the bearing 30 is D3, which satisfies 0.5mm≤D3≤1mm; and the interval distance between the outer ring 31 and the shell 10 in the axial direction of the bearing 30 is D4, which satisfies 1mm≤D4≤2mm.

When D1>1mm, or D2>1mm, the gap between the toy ring 40 and the connecting piece 20 and the shell 10 is too large, and there is a risk that impurities from the outside will enter the bearing 30 and cause damage to the bearing 30.
[0065] When D3<0.5mm, or D4<1mm, due to factors such as size tolerance and assembly tolerance, there is a risk of wear caused by movement interference between the outer ring 31 and the shell 10. When D3>1mm, or D4>4mm, the gap between the outer ring 31 and the shell 10 is too large, and there is a risk that impurities from the outside will enter the bearing 30 and cause damage to the bearing 30.
[0066] By setting the interval distance of the playing ring 40 and the connecting piece 20 in the radial direction of the bearing 30 as D1, satisfying 0.5mm (millimeter) ≤D1 ≤1mm; the interval distance of the playing ring 40 and the shell 10 in the axial direction of the bearing 30 as D2, satisfying 0.5mm ≤D2 ≤1mm; the interval distance of the outer periphery surface of the outer ring 31 and the shell 10 in the radial direction of the bearing 30 as D3, satisfying 0.5mm ≤D3 ≤1mm, and the interval distance of the outer ring 31 and the shell 10 in the axial direction of the bearing 30 as D4, satisfying 1mm ≤D4 ≤2mm, the risk of foreign matter entering the inside of the battery assembly 100 to cause abrasion is reduced under the premise that the playing ring 40, the bearing 30, the connecting piece 20 and the shell 10 will not be abraded.
