Detailed Description

The present invention will be further described by way of examples with reference to the accompanying drawings, which are not intended to limit the scope of the invention.

As shown in fig. 1, the present embodiment provides an electric core assembly 100. The battery cell assembly 100 includes a battery cell support 105, a plurality of battery cells 101 disposed in the battery cell support 105, and a bus bar 103 connecting the plurality of battery cells 101 in series.

In this embodiment, a cylindrical battery cell 101 is taken as an example, but the present invention is not limited thereto, and the battery cell 101 in the battery cell assembly 100 of the present invention may also be a rectangular parallelepiped, a cube, or the like.

The bus bar 103 is a metal sheet, and a metal having a good conductivity, such as copper, is used.

Fig. 2-6 illustrate a cell support 105 according to a preferred embodiment of the present invention. Fig. 2 is a schematic view from above of the cell holder 105, and fig. 4 is a schematic view from below of the cell holder 105, in which the cells 101 are placed in the cell holder 105 in fig. 2 to 5.

The cell holder 105 includes: a body 107. A plurality of cell accommodating portions 109 are provided inside the body 107. The two ends of the battery cell accommodating portion 109 are respectively provided with a first opening 111 and a second opening 112, the first opening 111 is provided with a blocking portion 115 for preventing the battery cell 101 from being separated, the edge of the second opening 112 is provided with an elastic buckle 120, and the elastic buckle 120 is configured to prevent the battery cell 101 from being separated from the battery cell accommodating portion 109.

The second buckle of the cell accommodating portion 109 of the cell support 105 is provided with an elastic buckle 120, so that the cell 101 is prevented from falling out of the open end of the cell support 105 after being placed in the cell accommodating portion 109.

As shown in fig. 3, the elastic buckle 120 includes a connection portion 121 and a protrusion portion 122, the connection portion 121 is connected to an edge of the second opening 112 and extends along an axis direction of the cell accommodating portion 109, the protrusion portion 122 is disposed at the other end of the connection portion 121 far away from the cell accommodating portion 109, and the protrusion portion 122 protrudes toward the axis of the cell accommodating portion 109. The axial direction here is a direction extending from the first opening 111 to the second opening 112 of the single cell accommodating portion 109, parallel to the center line of the cell accommodating portion 109, and in the present embodiment, the axial direction of the cell accommodating portion 109 is a cylindrical axial direction, as illustrated by the cylindrical battery cell 101.

The projection 122 has a blocking surface 124, and the blocking surface 124 faces the cell accommodating portion 109 in the axial direction of the cell accommodating portion 109.

The blocking surface 124 is less than or equal to 0.5mm from the second opening 112. The distance between the blocking surface 124 and the second opening 112 is sufficiently small to avoid substantial wobbling of the cell 101 within the cell holder 105.

The shape of the cell accommodation portion 109 is adapted to the shape of the individual cells 101. Since the cylindrical battery cell 101 of the present embodiment is illustrated, the battery cell accommodating portion 109 is cylindrical, and in other embodiments, the battery cell accommodating portion 109 may also be a rectangular parallelepiped, a square cube, or the like.

The protruding portion 122 has a guide surface 125, the guide surface 125 is provided on the opposite side of the stopper surface 124, and the guide surface 125 is inclined toward the cell accommodating portion 109 side in the direction toward the axis of the cell accommodating portion 109. By providing the inclined guide surface 125, the insertion of the battery cell 101 from the second opening 112 is facilitated. When the battery cell 101 is put into the battery cell accommodating portion 109 from the second opening 112, the battery cell 101 abuts against and presses the guide surface 125, so that the elastic buckle 120, specifically the connecting portion 121, is bent and deformed in a radially outward direction of the battery cell accommodating portion 109, and after the battery cell 101 completely enters the battery cell accommodating portion 109, the elastic buckle 120, specifically the connecting portion 121, is restored to its original shape. When the battery cell support 105 rocks, the battery cell 101 abuts against the blocking surface 124 of the elastic buckle 120, so that the battery cell cannot be separated from the battery cell accommodating part 109, and meanwhile, the battery cell 101 cannot greatly rock in the battery cell support 105 because the blocking surface 124 is short enough away from the battery cell 101. The length of the battery cell 101 is equivalent to that of the cell accommodating portion 109, that is, two end faces of the battery cell 101 are flush with edges of the first opening 111 and the second opening 112, respectively.

A plurality of elastic buckles 120 are equidistantly arranged along the edge of the second opening 112, so that the battery cell 101 is balanced in force.

The adjacent cell accommodating portions 109 have a first opening 111 and a second opening 112 at the same end, respectively. The electrodes of adjacent cells 101 are oppositely disposed, thereby facilitating the series connection of adjacent cells 101.

In other embodiments, the adjacent cell accommodating portions 109 may have the first openings or the second openings at the same end, and the electrodes of the adjacent cells are disposed in the same direction, so as to conveniently connect the adjacent cells in parallel.

In the present embodiment, the stopper 115 of the first opening 111 is a plate-shaped member extending from the edge of the first opening 111 toward the inside of the first opening 111, since the bus bar 103 needs to be provided, the stopper 115 preferably does not cover the entire first opening 111, and the stopper 115 has a notch leading to the second opening 112 adjacent to the first opening 111 provided with the stopper 115, the notch being used to accommodate the bus bar 103. The gap is arranged, so that the bus bar 103 can connect the adjacent electric cores 101 in series.

The edge of the second opening 112 is provided with a projection 117 directly connected to the blocking portion 115 of the adjacent first opening 111 so as to form a recess to accommodate the busbar 103. The boss 117 does not interfere with the insertion of the battery cell 101 into the cell accommodating portion 109. The bosses 117 are discontinuous along the edges of the second opening 112, and the resilient catches 120 are disposed between adjacent bosses 117. Although the present embodiment illustrates only two elastic buckles 120, the present invention is not limited thereto, and those skilled in the art may set the number of the elastic buckles 120 as needed.

In the description of the present invention, it is to be understood that the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", and the like indicate orientations or positional relationships based on those shown in the drawings, and are only for convenience of description and simplification of description, and do not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore, should not be construed as limiting the present invention.

Although specific embodiments of the present invention have been described above, it will be understood by those skilled in the art that this is by way of example only and that the scope of the invention is defined by the appended claims. Various changes and modifications to these embodiments may be made by those skilled in the art without departing from the spirit and scope of the invention, and these changes and modifications are all within the scope of the invention.
