Detailed Description

In the following, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments may be modified in various different ways, all without departing from the spirit or scope of the present invention. Accordingly, the drawings and description are to be regarded as illustrative in nature, and not as restrictive.

Embodiments of the present invention provide a battery carrying device that can be used to support and load a battery in an EV or HEV. As shown in fig. 1, the battery carrier according to the embodiment of the present invention may include a floor sheathing 10, a cooling plate 20, and a side plate 30. Among them, a battery (not shown in the drawings) may be disposed in the battery carrying region 70 enclosed by the side plates 30 and the cooling plate 20. In one embodiment, the battery carrying device may include a plurality of cross members 50 and longitudinal members 60, thereby dividing the battery carrying region 70 into a plurality of cell regions 71, and each cell region 71 may be provided with a battery.

The backplate 10 is disposed at the bottom of the battery carrier and may be used to support and protect other components (e.g., the cooling plate 20) and the battery, etc. in the battery carrier. The cooling plate 20 is tiled on the upper surface of the backplate 10 to reduce the temperature of the battery and help dissipate heat from the battery, thereby prolonging the life of the battery. One or more side plates 30 may be disposed at the outer circumference of the cooling plate 20, and the embodiment is not limited thereto. For example: the side plate 30 may be provided at each side of the cooling plate 20, or the side plates 30 may be provided at the left and right sides of the cooling plate 20, respectively.

In one embodiment, the cooling plate 20 may include a plurality of first cooling plate assemblies and connecting members disposed at intervals, and the plurality of first cooling plate assemblies and the plurality of connecting members are distributed on the upper surface of the backplate 10. FIG. 2 shows two adjacent first cooling plate assemblies 21A and 21B of the plurality of first cooling plate assemblies, and a joining assembly 22A of the plurality of joining assemblies with one of the joining assemblies disposed between the first cooling plate assemblies 21A and 21B.

As shown in fig. 2, the first cooling plate assemblies 21A and 21B are located on the left and right sides of the joining assembly 22A, respectively. The left and right sides B2 of the first cooling plate assembly 21A may each have protrusions 210, the left and right sides B1 and a1 of the first cooling plate assembly 21B may each have protrusions 210, and the left and right sides a2 and a1 of the linkage assembly 22A may each have recesses 220. The shape of the protrusion 210 and the recess 220 match so that the recess 220 can receive the protrusion 210.

The protrusion 210 and the recess 220 may be bonded. Fig. 3 illustrates the bonding process of the joining assembly 22A, the first cooling plate assemblies 21A and 21B. As shown in fig. 3, a gel 240 may be applied within the recess 220 to bond the protrusion 210 and the recess 220 together, thereby forming the structure shown in fig. 2. Preferably, as shown in FIG. 2, when the protrusion 210 is bonded to the recess 220, the left side A2 of the connection assembly 22A is in contact with the right side B2 of the connected first cooling plate assembly 21A; the right side A1 of the joining assembly 22A is in contact with the left side B1 of the joined first cooling plate assembly 21B.

It should be noted that fig. 2 and 3 only show a part of the first cooling plate assembly and a part of the connecting assembly, and the number and shape of the convex portions 210 and the concave portions 220 are not limited in this embodiment, as long as the connecting assembly and the first cooling plate assembly are matched in shape and number of the convex portions and the concave portions on the side surfaces to be connected.

For example: as shown in fig. 4, the joining assembly 22B at the left edge of the cooling plate 20 may be connected only to the first cooling plate assembly 21C at its right side, and therefore the joining assembly 22B has a recess 220 only on its right side a3, the shape of the recess 220 matching the shape of the protrusion 210 of the first cooling plate assembly 21C. Another example is: as shown in fig. 5, the right side B3 of the first cooling plate assembly 21D at the right edge of the cooling plate 20 does not need to have a connection assembly, so the right side B3 may have no protrusions, only the left side B4 may have protrusions 210, and the shape of the protrusions 210 on the left side B4 may match the shape of the recesses 220 on the right side a4 of the connection assembly 22C.

in one embodiment, as shown in FIGS. 2 and 3, second cooling plate assemblies 23A and 23B are disposed above the first cooling plate assemblies 21A and 21B, respectively. A coolant pipe 40 is connected between two adjacent second cooling plate assemblies 23A and 23B. Wherein, a sealing ring (not shown) is sleeved on the outer wall of the joint of the cooling liquid pipeline 40 and the second cooling plate assembly. The first cooling plate assemblies 21A and 21B have cooling fluid passages 230 therein. The coolant passages 230 communicate with the coolant line 40 to allow coolant to flow between the respective first cooling plate assemblies (including 21A and 21B). It should be noted that fig. 3 does not show a cross section of the portion of the cooling liquid channel 230 communicating with the cooling liquid duct 40, but it is understood that the two can communicate in any manner or at any position.

In one embodiment, the first cooling plate assembly is welded to the second cooling plate assembly. Fig. 2 and 3 show a weld line C-C between the first cooling plate assembly 21A and the second cooling plate assembly 23A, and a weld line C-C between the first cooling plate assembly 21B and the second cooling plate assembly 23B. In one embodiment, coolant lines 40 may run through each second cooling plate assembly in the same row.

In one embodiment, the lower surface of the cooling plate 20 is adhered to the upper surface of the bottom guard plate 10, and the connecting component is coplanar with the bottom surface of the first cooling plate component, so that the cooling plate 20 and the bottom guard plate 10 can be adhered uniformly, and the adhesion effect is improved.

in one embodiment, as shown in fig. 6, the bottom of the side plate 30 may include a first contact end 31 disposed on the cooling plate 20 (e.g., the upper surface of the cooling plate 20), and a second contact end 32 disposed on the apron plate 10 (e.g., the upper surface of the apron plate 10). Of these, fig. 6 shows only a part of the apron plate 10 and a part of the cooling plate 20. In the direction of the view shown in fig. 6, the height of the first contact end 31 is greater than the height of the second contact end 32. For example: the surface H1 of the bottom of the first contact end 31 is higher than the surface H2 of the bottom of the second contact end 32 with the surface H0 of the backplate 10 as a reference.

Thus, the joining process of the cooling plate 20 and the side plate 30 and the joining process of the floor sheathing 10 and the side plate 30 may be different. For example: the cooling plate 20 and the side plate 30 may be bonded, and the bottom cover sheet 10 and the side plate 30 may be welded or riveted. Further, the strength of fixing the side plate 30 to the floor panel 10 can be increased while ensuring the sealing property between the side plate 30 and the cooling plate 20.

In one embodiment, the cooling plate 20 may be bonded to the side plate 30, and the bottom cover sheet 10 and the side plate 30 may be welded or riveted. In the first contact end portion 31, a groove 31A is provided at a position corresponding to the cooling plate 20, that is, at a contact surface with the cooling plate 20, and an adhesive can be placed in the groove 31A, thereby improving the adhesive strength.

In one embodiment, as shown in fig. 6, the bottom of the side plate 30 has an opening 33, and the opening 33 is located between the first contact end 31 and the second contact end 32, so that a protective area is formed between the first contact end 31 and the second contact end 32 to enhance the sealing performance between the side plate 30 and the cooling plate 20.

In one embodiment, as shown in FIG. 6, there is a hollow area 340 above the opening 33. The size and shape of the hollow region 340 is not limited in this embodiment. For example: the side panel 30 may include a top member 330, a first side member 310, and a second side member 320, with a hollow area 340 defined by the top member 330, the first side member 310, and the second side member 320. The bottom of the first side member 310 forms the first contact end 31 and the bottom of the second side member 320 forms the second contact end 32.

Therein, the cooling plate 20 may partially close the opening 33, thereby partially sealing the hollow area 340, i.e. the second contact end 32 may not contact the side of the cooling plate 30. Alternatively, the cooling plate 20 may completely close the opening 33, thereby completely sealing the hollow area 340, i.e. the second contact end 32 may be in contact with the side of the cooling plate 30.

An embodiment of the present invention further provides a vehicle, which may include the above battery carrying device, a battery, and a coolant pipe. The vehicle of the present embodiment may be an EV or HEV. Other configurations of the vehicle of the present embodiment can be adopted by various technical solutions known by those skilled in the art now and in the future, and will not be described in detail here.

According to the battery bearing device provided by the embodiment of the invention, the connecting assemblies and the first cooling plate assemblies are bonded together by an embedding method, so that the bonding strength can be improved. Further, the structure of the side plate enables the side plate and the cooling plate to be fixed in different connection modes, the side plate and the bottom protection plate to improve the fixing strength among all the parts and the sealing performance between the side plate and the cooling plate, and further the yield of product generation is improved.
