Referring to fig. 1 and 5 to 7, in one embodiment, the accommodating member 20 is a battery barrel, and the opening edge of the battery barrel is wound with a guiding wall 21, and the caliber of the guiding wall 21 tends to decrease in a direction approaching to the bottom wall of the battery barrel. The guide 50 is, for example, a guide rail provided at a connection portion between the opening edge and the guide wall 21. Thus, when the power battery 40 is mounted in the battery barrel, the guiding wall 21 firstly passes through the guiding wall 21, the guiding wall 21 plays a guiding role on the power battery 40, and when the power battery 40 slides downwards and moves to contact with the guiding piece 50, the guiding piece 50 plays a guiding role and also plays a buffering role, so that the power battery 40 is smoothly and stably mounted in the battery barrel. In addition, when the guide 50 is a guide rail, the buffering and positioning effects are good.

Referring to fig. 1, 5 to 7, the caliber of the guide wall 21 is reduced in a direction approaching the bottom wall of the battery barrel, that is, the wall surface of the guide wall 21 forms an included angle with the wall surface of the inner side wall of the battery barrel, in other words, the guide wall 21 is in a horn shape, so as to guide the bottom end of the power battery 40.

In particular, in order to have a better positioning effect on the power battery 40, the battery barrel is specifically configured to follow the power battery 40, i.e. when the cross section of the power battery 40 is square, circular, elliptical or triangular, the cross section of the battery barrel is correspondingly configured to be square, circular, elliptical or triangular. Of course, as some alternatives, the shape of the power cell 40 may be made different from the shape of the battery tub.

It should be noted that, the "guide wall 21" may be "a part of the battery can", that is, the "guide wall 21" is integrally formed with "other part of the battery can"; or a separate member which is separable from the other part of the battery can, that is, the guide wall 21 may be manufactured separately and then combined with the other part of the battery can into a whole.

In one embodiment, the number of mounting portions 33 includes, but is not limited to, four, with four corresponding mounting seats 16 on frame 10, with each mounting portion 33 being removably coupled to each mounting seat 16 by a second fastener 80.

Optionally, the second fastener 80 includes, but is not limited to, a screw, bolt, pin, rivet, snap, or the like.

Referring to fig. 4 and 8, in one embodiment, two mounting portions 33 are disposed on a bottom surface of the pressure-bearing portion 31, which is far from the main portion 32, and the two mounting portions 33 are protruding portions extending toward a bottom portion of the frame 10. The interval between the two convex portions (shown as M in fig. 4) is located opposite to the wiring portion 41 of the power battery 40. On the one hand, the pressure-bearing part 31 is respectively connected with the two mounting seats 16 corresponding to the positions on the frame 10 through the two mounting parts 33, so that the helmet box 30 and the frame 10 can be connected and fixed, the pressure-bearing part 31 can press the top end of the power battery 40 below the helmet box, and the stability of the power battery 40 is improved; on the other hand, the space position (shown as M in fig. 4) of the two protrusions is opposite to the position of the wiring portion 41 of the power battery 40, so that the lead wire of the wiring portion 41 of the power battery 40 can be led out through the space position (shown as M in fig. 4) of the two protrusions, without interfering with the wiring of the power battery 40.

The "mounting portion 33" may be "a part of the helmet box 30", that is, the "mounting portion 33" is integrally formed with "other parts of the helmet box 30"; or may be a separate member that is separable from the other portion of helmet box 30, i.e., mounting portion 33 may be manufactured separately and then integrated with the other portion of helmet box 30.
