As shown in fig. 1 to 3, in an embodiment of the present utility model, the elastic support 300 includes a support portion 310 and an elastic portion 320. Specifically, the elastic portion 320 is formed by folding the side edge of the support portion 310 toward the battery pack 100. On this basis, the elastic support 300 is disposed on the base plate 200 via the support portion 310, and the battery pack 100 is disposed on the elastic portion 320 of the elastic support 300. In other words, the battery pack 100 is disposed on the bottom plate 200 through the bearing of the elastic support 300. Through the above structural design, the utility model can bear the battery pack 100 through the elastic support 300, and the elastic deformation of the elastic part 320 is utilized to compensate the installation flatness error between the battery pack 100 and the bottom plate 200, so that the assembly of the battery pack 100 and the bottom plate 200 meets the flatness requirement, thereby improving the structural stability and reliability of the battery pack.

As shown in fig. 3, in an embodiment of the present utility model, the elastic portion 320 of the elastic support 300 may have an arc-shaped section 321 and a linear section 322. Specifically, the arc-shaped section 321 is substantially arc-shaped, such as arc-shaped, elliptical arc-shaped, etc., and one end of the arc-shaped section 321 is connected to a side of the supporting portion 310. The linear section 322 is substantially linear, and one end of the linear section 322 is connected to the other end of the arc-shaped section 321, and the other end of the linear section 322 extends obliquely toward the battery pack 100. It should be noted that the above description of arc shape and straight line shape can be understood as the shape of different portions of the orthographic projection of the elastic portion 320 on a reference plane, which may be perpendicular to the base 200 (i.e., the reference plane is a vertical plane), and the reference plane is perpendicular to the extending direction (for example, but not limited to, the first direction X described below) of the elastic support 300 (i.e., the support portion 310). Through the structural design, the utility model can provide better elastic deformation and buffering functions by utilizing the arc-shaped section 321, thereby further improving the supporting effect of the elastic supporting piece 300 and compensating the effect of mounting flatness errors. In some embodiments, the elastic portion 320 may have only a linear section 322, for example, the elastic portion 320 may be entirely linear, the elastic portion 320 may have only an arc section 321, for example, the elastic portion 320 may be entirely arc-shaped, or the elastic portion 320 may have other shapes or a combination of shapes, which is not limited to the embodiment.

As shown in fig. 2, in an embodiment of the present utility model, the battery pack 100 includes a plurality of batteries arranged along a first direction X, that is, the first direction X is an arrangement direction of the plurality of batteries of the battery pack 100. On this basis, the battery pack according to the present utility model may include a plurality of elastic supports 300, and the elastic supports 300 are spaced apart along a second direction Y perpendicular to the first direction X. The battery pack 100 is simultaneously disposed on the elastic parts 320 of the plurality of elastic supports 300. Through the above structural design, the present utility model can optimize the supporting effect on the battery pack 100 by using the plurality of elastic supporting members 300, and can further compensate for the installation flatness errors between the battery pack 100 and the bottom plate 200 at a plurality of positions along the first direction X and the second direction Y, thereby further improving the structural stability and reliability of the battery pack. In some embodiments, when the battery pack includes a plurality of elastic supports 300, the plurality of elastic supports 300 may be spaced apart in other directions, or at least two elastic supports 300 may be arranged side by side or end to end. Furthermore, the battery pack according to the present utility model may also include only one elastic support 300, which is not limited to the present embodiment.

In an embodiment of the present utility model, the supporting portion 310 of the elastic support 300 may be adhesively connected with the base plate 200. For example, the bottom of the support part 310 may be adhered to the bottom plate 200 by double-sided adhesive tape. Through the structural design, the connecting structure of the elastic support 300 and the bottom plate 200 can be simplified, the number of parts is reduced, and the assembly is convenient. In some embodiments, the elastic support 300 may be connected to the base 200 by other means, such as connection, but not limited to this embodiment.

As shown in fig. 4, in an embodiment of the present utility model, the battery pack 100, the base plate 200, and the elastic support 300 may be adhered via an adhesive layer 400. For example, when the battery pack 100 is assembled with the base plate 200, and the elastic support 300 is mounted on the base plate 200 and the battery pack 100 is supported on the elastic support 300, the adhesive layer 400 may be formed after the adhesive layer is adhered to the gap between the battery pack 100 and the base plate 200. The adhesive layer 400 is adhered to the bottom surface of the battery pack 100, the top surface of the bottom plate 200, and the elastic support 300. Through the above structural design, when the battery pack 100 and the bottom plate 200 are bonded by the adhesive layer 400, the thickness of the adhesive layer 400 can be controlled by using the elastic support 300, so that the adhesive material consumption can be accurately controlled on the basis of ensuring the adhesive effect, and the waste of material cost is avoided.

As shown in fig. 5 to 7, based on the structural design that the battery pack 100, the base plate 200, and the elastic support 300 are bonded via the adhesive layer 400, in an embodiment of the present utility model, the support portion 310 of the elastic support 300 may extend along the first direction X, and the elastic support 300 may include a plurality of elastic portions 320, and the elastic portions 320 may be spaced apart along the first direction X. Accordingly, a glue overflow path P is formed between two adjacent elastic portions 320. Specifically, when the battery pack 100 is carried on the elastic support 300, a space between the bottom surface of the battery pack 100 and the top surface of the bottom plate 200 forms an accommodating space for the adhesive material, and after the adhesive material is poured, the battery pack 100 and the bottom plate 200 can be pressed by applying force (for example, the battery pack 100 is pressed down) relatively so as to improve the adhesive assembly effect, and part of the adhesive material can overflow through the adhesive overflow channel P in the process. Through the above structural design, the present utility model can utilize the glue overflow channel P formed by the elastic support 300 to realize the glue overflow function, thereby further improving the gluing effect of the battery pack 100 and the bottom plate 200. It should be noted that, in the present embodiment, the arrangement of the plurality of batteries of the battery pack 100 is taken as an example, and it should be understood that, in some embodiments, the first direction X may be other directions than the arrangement direction of the batteries, and is not limited to the present embodiment.

Based on the structural design that the elastic support 300 includes a plurality of elastic portions 320, in an embodiment of the utility model, the battery pack 100 includes a plurality of batteries, and the first direction X is an arrangement direction of the plurality of batteries. On this basis, each cell may correspond to the position of at least one elastic portion 320, respectively. Through the above structural design, the present utility model can ensure that each battery of the battery pack 100 is supported on the elastic portion 320 of the elastic support 300, thereby avoiding that a part of the batteries are not supported by the elastic portion 320 and increasing the mounting flatness error.

Based on the structural design that each cell corresponds to the position of at least one elastic portion 320, respectively, in an embodiment of the present utility model, each cell may correspond to the position of at least two elastic portions 320, respectively. Through the above structural design, on the basis of ensuring that each battery is supported by the elastic part 320 of the elastic support member 300, the utility model can further optimize the supporting effect of the elastic support member 300 on each battery, further optimize the effect of compensating the error of the installation flatness, and further improve the structural stability and reliability of the battery pack.

Based on the structural design that each cell corresponds to the position of at least one elastic portion 320, in an embodiment of the present utility model, each elastic portion 320 may correspond to the position of only one cell, in other words, the gap between two adjacent cells may not correspond to the elastic portion 320. Through the above structural design, the utility model can avoid that the position of the elastic part 320 corresponds to the position of the gap between two adjacent batteries, thereby ensuring that each elastic part 320 of the elastic support 300 can be supported at the bottom of the battery, further optimizing the effect of compensating the error of the installation flatness, and further improving the structural stability and reliability of the battery pack.

As shown in fig. 6, based on the structural design that the elastic support 300 includes a plurality of elastic portions 320, in an embodiment of the utility model, a side edge of the support portion 310 connected with the elastic portions 320 may be provided with a notch 311 at a position between two adjacent elastic portions 320. Accordingly, due to the arrangement of the notch 311, the side edge of the supporting portion 310 to which the elastic portion 320 is connected may approximately take a wavy shape. Through the above structural design, the utility model can further increase the glue overflow area of the glue overflow channel P by using the notch 311, and can enhance the structural strength of the junction between the wavy side edge and the elastic part 320. In some embodiments, the side of the support portion 310 to which the elastic portion 320 is connected may also have a straight profile, which is not limited to the present embodiment.

In an embodiment of the present utility model, the material of the elastic support 300 may be an insulating material, for example, an adhesive tape may be used for the elastic support 300.

In one embodiment of the present utility model, the bottom plate 200 may be a liquid cooling plate.
