The cell cover plate 100 according to the embodiment of the first aspect of the present invention includes: the cover plate body 10, the pole 20 and the pole mounting block 30.
As shown in fig. 1 and 2, the cover plate body 10 has a mounting hole 11, the pole post 20 is inserted into the mounting hole 11, the pole post mounting block 30 is located at one side of the cover plate body 10, one end of the pole post 20 extends out of the cover plate body 10 and is inserted into the pole post mounting block 30, and the pole post 20 is connected with the pole post mounting block 30.
The axial direction of the pole 20 is the first direction a, the length direction of the cover body 10 is the second direction B, and the width direction of the cover body 10 is the third direction C.
Wherein the pole 20 is non-circular, the cover plate body 10 is strip-shaped, the maximum sizes of the pole 20 are a and b respectively along the length direction and the width direction of the cover plate body 10, and a is more than or equal to b, the cross-sectional area of the column body 21 is S,
the post 20 passes through the mounting hole 11 of the cover plate body 10 and is matched with the post mounting block 30 on one side of the cover plate body 10, namely, the post 20, the cover plate body 10 and the post mounting block 30 are sequentially distributed from inside (the side where the stop flange 22 is located) to outside (the side where the post mounting block 30 is located) along the first direction a, and the cover plate body 10 and the post mounting block 30 are sleeved on the post 20. Since the pole 20 is of a non-circular design, its maximum dimension along the length direction (second direction B) of the cover body 10 is a, and its dimension along the width direction (third direction C) of the cover body 10 is B.
From this, adopt non-circular utmost point post 20, and increase its size in the length direction of apron body 10 as far as possible, make the sectional area of the utmost point post 20 of the above-mentioned shape that can hold be greater than the sectional area of the circular utmost point post 20 that can hold, like this, under the limited prerequisite of apron body 10 width, the area of overflowing of utmost point post 20 has been increased, the ability of overflowing has been improved, make the electric core apron 100 that has above-mentioned utmost point post 20 can satisfy the demand of the increasingly high capacity of battery and the demand of the faster and faster speed of charging, and can reduce the size of utmost point post 20 at apron body 10 width direction, so that electric core apron 100 can use in more occasions.
Optionally, the cross section of the pole 20 is an ellipse, a major axis of the ellipse extends along the length direction of the cover body 10, and a minor axis of the ellipse extends along the width direction of the cover body 10.
Thus, the pole 20, which has an elliptical cross-section, has an area that can actually flow through

The runway shape is formed by splicing a rectangle and two approximate semicircles, and the two semicircles are positioned at two ends of the rectangle and are symmetrically distributed.
Thus, if the cross section of the column 21 is racetrack shaped, the actual flow area can be approximated to the elliptical flow area
If the cross-sectional area of the column 21 is rectangular, the area that can actually flow is s3＝ab。
Optionally, as shown in fig. 4, the cross section of the pole 20 includes a circular shape and a first protrusion 211 and a second protrusion 212 connected to the outer edge of the circular shape, and the first protrusion 211 and the second protrusion 212 both protrude along the length direction of the cover body 10 and protrude in opposite directions. I.e. the pole 20 is a combination of a cylinder, a first protrusion 211 and a second protrusion 212, both of which may be rectangular or semicircular in cross-section.
Therefore, on the basis of the maximum allowable circular cross section, two bulges extending in the length direction of the cover plate body 10 are added, and the design also increases the flow area of the pole 20.
Further, as shown in fig. 2, the pole 20 includes a post body 21 and a stop flange 22, the stop flange 22 is connected to the outer wall of the post body 21 and is in positioning fit with one side of the cover plate body 10, and the post body 21 and the pole mounting block 30 are welded at the ends.
