Specific Embodiments

[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art belong to the scope of protection of the present utility model.

[0022] Embodiment 1:

[0023] Figures 1 - 6As shown in the figure, a stamping-type aluminum pole column described in this embodiment includes a pole column body 1, which is formed by an aluminum plate. The aluminum plate is stamped to form a hole structure 10, a circular ring portion 11 formed at one port of the hole structure 10, a closing plate 13 that closes the port of the circular ring portion 11, and a circular skirt 12 continuously arranged on the outer peripheral side of the bottom of the circular ring portion 11. A connecting convex portion 14 is convexly provided on the top of the closing plate 13. The circular ring portion 11 is continuously arranged along the edge of one port of the hole structure 10. A cavity 16 is formed by enclosing between the inner side wall of the closing plate 13 and the inner side wall of the circular ring portion 11. Since the aluminum pole column can be bent and formed on the aluminum plate, it is suitable for die stamping, and the time required for die stamping is short, which further improves the forming efficiency and greatly improves mass production.

[0024] Based on the above aluminum pole column stamping, generally, the aluminum pole column of this embodiment is formed by a stamping method in which an aluminum strip and a progressive die are mutually matched. The forming of the circular ring portion 11 is to stamp the center position of the aluminum plate in the aluminum strip from bottom to top to form a convex hull and a cavity 16 below the closing plate 13 located at the convex hull, and at the same time, a connecting convex portion 14 is formed at the center position of the upper top surface of the closing plate 13.

[0025] Preferably, the outer shape of the circular skirt 12 is a square structure; both the circular ring portion 11 and the connecting convex portion 14 are circular structures. However, the outer shapes of the circular skirt 12, the circular ring portion 11, and the connecting convex portion 14 can also be set to other shapes according to actual situations.

[0026] Further, after the aluminum pole column is assembled in the pole column hole 31 of the top cover assembly 3, the connecting convex portion 14 of the aluminum pole column then penetrates through the center hole 21 of the cap 2 of the top cover assembly 3.

[0027] Embodiment Two:

[0028] As Figures 1 - 3 shown, a stamping-type aluminum pole column described in this embodiment has a general structure similar to that of Embodiment One, but the difference is that a plurality of columns 15 arranged in a circular array are formed on the outer side wall of the closing plate 13; the height of the columns 15 is less than the height of the connecting convex portion 14; the plurality of columns 15 are arranged around the connecting convex portion 14. Among them, after the aluminum pole column is assembled in the pole column hole 31 of the top cover assembly 3, the connecting convex portion 14 of the aluminum pole column then penetrates through the center hole 21 of the cap 2, and the plurality of columns 15 respectively penetrate through the corresponding positioning holes 22 on the cap 2 of the top cover assembly 3, so as to realize the positioning after the aluminum pole column is assembled.

[0029] Embodiment Three:

[0030] As Figures 4 - 6As shown, a stamping-type aluminum pole column described in this embodiment has a general structure similar to that of Embodiment 1 or Embodiment 2. However, the difference is that at least one outer side of the annular skirt 12 is integrally provided with a conductive connection piece 17, and a welding area for welding with the tab of the battery cell is provided on the outer side of the conductive connection piece 17.
