Referring to fig. 1 to 6, the present utility model provides a tray 100, which is adapted to a battery pack 200.

The tray 100 includes a first frame 110, a second frame 120, and an angle reinforcing member 130.

The first housing 110 is formed with an accommodating space 113, and the second housing 120 is connected to the first housing 110 and partitions the accommodating space 113 into at least two subspaces.

The angle reinforcing member 130 is disposed at a connection position of the first and second frames 110 and 120, and is connected to the first and second frames 110 and 120. To improve the coupling strength of the first and second frames 110 and 120, thereby improving the structural strength of the entire tray 100.

For example, when the receiving space 113 is partitioned into two subspaces, one subspace may be used to stack a plurality of battery cells 250, and the other subspace may be used to stack the battery cells 250, the battery management system 220 (BMS), the distribution box 230 (BDU), and the like according to actual conditions. According to practical situations, more than two subspaces may be provided as subspaces for stacking a plurality of battery cells 250. More than two subspaces may also be provided as subspaces housing the battery management system 220 and/or the distribution box 230. So configured, a new tray is provided, in which the battery module is not mounted in the tray of the battery pack, but the tray 100 of the battery pack is integrated with the housing of the battery module, and the plurality of battery cells 250 are disposed in the subspace of the tray.

In the present embodiment, the second frame 120 includes two first beams 121. Referring to fig. 1 to 3, two first beams 121 are spaced apart, and the two first beams 121 are connected to the frame and divide the receiving space 113 into a first subspace 113A, a second subspace 113B, and a third subspace 113C.

The first subspace 113A is used for stacking a plurality of battery cells 250, the second subspace 113B is also used for stacking a plurality of battery cells 250, and the third subspace 113C is used for stacking a BMS and a BDU. Referring to fig. 1, the second subspace 113B is smaller than the first subspace 113A. The stacking direction of the plurality of cells 250 in the first subspace 113A is a first direction D1, and the stacking direction of the plurality of cells 250 in the second subspace 113B is a second direction D2, the second direction D2 being different from the first direction D1. In other embodiments of the utility model not shown, the stacking direction of the cells 250 within the first and second subspaces 113A and 113B may also be the same.

The second frame 120 may further include a stop beam 122, for example. Referring to fig. 2, the second frame 120 includes two first beams 121 and two stopper beams 122. The first beams 121 extend in a first direction D1, and the stopper beams 122 extend in a second direction D2 and are located between the two first beams 121.

Specifically, the frame includes a second beam 111 and a third beam 112 connected. One of the two first beams 121 is connected to the second beam 111. The angle reinforcing member 130 is provided at a connection position of the first beam 121 and the second beam 111.

Specifically, the first beam 121 has a first surface 121A. The second beam 111 has a second surface 111A. The second surface 111A and the first surface 121A form an angle at the connection location of the second beam 111 and the first beam 121.

It will be appreciated that the included angle may be an acute angle, a right angle or an obtuse angle. In the illustrated embodiment, the first beam 121 is inclined to the second beam 111 at an acute angle. In the illustrated embodiment, the first beam 121 extends in the first direction D1, and the third beam 112 extends in the second direction D2. The first beam 121 is perpendicular to the third beam 112.

The included angle reinforcing member 130 includes a first connection surface 131A and a second connection surface 132A. The first connecting surface 131A is attached to the first surface 121A, and the second connecting surface 132A is attached to the second surface 111A. The first beam 121 and the angle reinforcing member 130 may be connected at the position of the first connection surface 131A; the second beam 111 and the included angle reinforcing member 130 are connected at the position of the second connection surface 132A. The operation is facilitated, and the connection strength of the first beam 121 and the second beam 111 is made higher.

In particular, the structure of the angle reinforcing member 130 may be an L-shaped structural member including a first plate 131 and a second plate 132 connected. The first plate 131 has a first connection surface 131A, and the second plate 132 has a second connection surface 132A adjacent to the first connection surface 131A. The angle reinforcing member 130 may further provide a reinforcing rib 134 between the first plate 131 and the second plate 132 to further improve the connection strength of the first beam 121 and the second beam 111.

Specifically, the triangular tube includes a first plate 131, a second plate 132, and a third plate 133, which are connected end to end in sequence. It can be appreciated that the triangular tube has higher structural strength and better stability. The included angle reinforcing member 130 may be an integrally formed member.

Preferably, the first plate 131 and the second plate 132 arc-transition, the second plate 132 and the third plate 133 arc-transition, and the first plate 131 and the third plate 133 arc-transition. Referring to fig. 5 and 6, the included angle reinforcing member 130 is an integrally formed member, the first plate 131 (first connection surface 131A) and the second plate 132 (second connection surface 132A) are connected by an arc surface, the second plate 132 (second connection surface 132A) and the third plate 133 (third connection surface 133A) are connected by an arc surface, and the third plate 133 (third connection surface 133A) and the first plate 131 (first connection surface 131A) are connected by an arc surface, so that welding is facilitated. It will be appreciated that the connection (e.g., welding) is performed at the junction of the first beam 121 and the second beam 111, where the angle is acute, and the space is too small to facilitate the welding operation, and the strength of the welded connection at this location cannot be ensured. The tray 100 of the present utility model increases the strength of the tray 100 by adding an included angle reinforcing member 130 at the position, thereby facilitating the welding operation.

Specifically, the first plate 131 is attached to the first surface 121A and welded to the first beam 121 at the edge, and the second plate 132 is attached to the second surface 111A and welded to the second beam 111 at the edge. Referring to fig. 4, the distribution of the weld beads 140 is shown when the included angle reinforcing member 130 is welded to the first beam 121 and the second beam 111. As shown in fig. 4, the weld beads 140 are located at the circumferential edges of the first plate 131, the second plate 132, and the third plate 133. The upper edge of the first plate 131 is welded to the first surface 121A and the upper surface of the second plate 132 is welded to the second surface 111A in a direction perpendicular to the tray 100 (the longitudinal direction of the triangular tube in the drawing).

In addition, the lower edge of the third plate 133 may be welded to the bottom of the tray 100.

The stiffener 134 may be disposed within the cavity 135. The ribs 134 may be provided, for example, at the median line of a triangle of triangular tube cross-section. Referring to fig. 5 and 6, in the present embodiment, the third connection surface 133A is perpendicular to the first beam 121. The reinforcing ribs 134 are configured as a connection plate, which is parallel to the third plate 133. The ribs 134 divide the cavity 135 into a first cavity 135A and a second cavity 135B along the longitudinal direction of the triangular tube itself (the axial direction, i.e., the extending direction of the cavity 135, the direction perpendicular to the drawing plane in fig. 6). A structure such as a cable may be disposed correspondingly within the first cavity 135A or/and the second cavity 135B. In the present embodiment, the included angle reinforcing member 130 is located in the second subspace 113B, and further divides the second subspace 113B.
