[0025] like Figure 1-Figure 3 As shown, an embodiment of the utility model provides a carrying device, including a cooling carrier plate 1 and a first crossbeam 2, the cooling carrier plate 1 is used to carry a battery module 4 and can cool the battery module 4, the first crossbeam 2 is arranged on the cooling carrier plate 1, and is used to define a carrying area 11 for carrying the battery module 4 on the cooling carrier plate 1, and the first crossbeam 2 has a guide portion 21, and the guide portion 21 can guide the battery module 4 to the carrying area 11 when the battery module 4 is placed in the carrying area 11.

[0026] The load-bearing device provided by the utility model can define a load-bearing area 11 for carrying a battery module 4 on the cooling carrier 1 by means of a first crossbeam 2 provided on the cooling carrier 1, that is, the first crossbeam 2 is located at the edge of the load-bearing area 11, and by providing the first crossbeam 2 with a guide portion 21, the battery module 4 can be guided by means of the guide portion 21 during the process of placing the battery module 4 into the load-bearing area 11, and the battery module 4 can be guided to the load-bearing area 11, thereby improving the accuracy of placing the battery module 4 in place at one time, and then during the process of placing the battery module 4 into the load-bearing area 11, the possibility of the edge bottom of the battery cell colliding with the first crossbeam 2 can be reduced, thereby reducing the possibility of damage to the blue film of the battery cell.

[0027] In one embodiment of the utility model, in the preset direction of the load-bearing area 11, the side of the guide portion 21 facing the load-bearing area 11 has a guide side surface 211, and in the preset direction of the load-bearing area 11, the guide side surface 211 gradually approaches the load-bearing area 11 from top to bottom, and the guide portion 21 guides the battery module 4 by contacting the battery module 4 through the guide side surface 211.

[0028] By providing a guide side surface 211 on a side of the guide portion 21 facing the load-bearing area 11 in a preset direction of the load-bearing area 11, the guide side surface 211 can contact the edge bottom of the battery module 4 to guide the battery module 4 during the process of placing the battery module 4 on the load-bearing area 11. By gradually approaching the load-bearing area 11 from top to bottom in the preset direction of the load-bearing area 11, on the one hand, the top of the guide side surface 211 can be away from the load-bearing area 11 relative to the bottom of the guide side surface 211 in the preset direction of the load-bearing area 11, thereby reducing the possibility of the bottom of the battery cell colliding with the top of the guide side surface 211 during the process of placing the battery module 4 on the load-bearing area 11, thereby reducing the possibility of the bottom of the battery cell colliding with the first crossbeam 2. On the other hand, during the process of gradually placing the battery module 4 on the cooling carrier 1 from top to bottom (such as Figure 2 As shown by the middle arrow, the battery module 4 is gradually guided to the carrying area 11 through the contact between the guiding side surface 211 and the bottom of the edge of the battery module 4.

[0029] Optionally, both opposite sides of the guide portion 21 may have guide side surfaces 211. Such a design is because in actual applications, a first beam 2 may define two bearing areas 11 for bearing the battery modules 4 on the cooling carrier 1, that is, the opposite sides of a first beam 2 may each have a bearing area 11, or in other words, a first beam 2 may be provided between two adjacent bearing areas 11, and the first beam 2 may serve as the edge of two adjacent bearing areas 11. Therefore, by making the opposite sides of the guide portion 21 have guide side surfaces 211, the battery modules 4 placed in the two bearing areas 11 adjacent to the first beam 2 can be guided by the two guide side surfaces 211 of the first beam 2, and the two battery modules 4 are respectively guided to the two bearing areas 11 corresponding to the two battery modules 4.

[0030] In an embodiment of the present invention, the guide side surface 211 may be a curved surface. However, the guide side surface 211 is not limited to a curved surface, for example, the guide side surface 211 may also be an inclined surface.

[0036] By making the connecting sub-portion 222 protrude in a preset direction of the supporting area 11 relative to the guide portion 21 toward the supporting area 11, when the battery module 4 is guided by the guide portion 21 and placed on the cooling carrier 1, the connecting sub-portion 222 can be located at the bottom of the edge of the battery module 4, so that it can be connected to the battery module 4 through the connecting sub-portion 222.
