[0043] Optionally, referring to Figure 1 , the sizes of at least two support members 1 along the first direction X are equal.

[0044] Specifically, the sizes of each support member 1 along the first direction X are equal to realize the standardized design of the support member 1, thereby improving the versatility of the support member 1, and further facilitating the stable connection of two adjacent support members 1 by using the fixing member 2.

[0045] It should be noted that the sizes of each support member 1 along the second direction Y can be equal or not equal, and the size of the support member 1 along the second direction Y can be flexibly determined according to the size of the battery cell 7, and the embodiments of the present application do not limit it.

[0046] Optionally, referring to Figure 1 and Figure 2 , the support member 1 is provided with a first positioning hole 112, and the fixing member 2 is provided with a plurality of second positioning holes 21 arranged at intervals along the second direction Y. The first positioning hole 112 and the second positioning hole 21 are positioned and connected, and the second direction Y is perpendicular to the first direction X.

[0047] Specifically, the number of the first positioning holes 112 on each second connecting portion 11 can be one or multiple, and the embodiments of the present application do not limit it; as Figure 1 shown, the fixing member 2 is provided with a plurality of second positioning holes 21 arranged at intervals along the second direction Y; a pin shaft or a bolt can be used to penetrate through the first positioning hole 112 and the second positioning hole 21 to realize the positioning connection between the first positioning hole 112 and the second positioning hole 21.

[0049] In this embodiment, the position of the support member 1 is defined by the positioning connection between the first positioning hole 112 and the second positioning hole 21, so as to reduce the probability of the support member 1 moving, thereby improving the connection stability between the support member 1 and the fixing member 2.

[0050] In some embodiments, when the second connecting portion 11 is provided with a jack 111, the fixing member 2 can be first inserted into the jack 111, and then a pin or a bolt is inserted into the first positioning hole 112 and the second positioning hole 21, thereby further defining the position of the support member 1.

[0051] In other embodiments, when the second connecting portion 11 is not provided with a jack 111, the fixing member 2 can be first abutted against the second connecting portion 11, and then a pin or a bolt is inserted into the first positioning hole 112 and the second positioning hole 21. The pin or the bolt is matched with the positioning hole to realize the detachable connection between the fixing member 2 and the second connecting portion 11.

[0052] Optionally, referring to Figure 1 , the distance between two adjacent second positioning holes 21 is equal.

[0053] Specifically, a plurality of second positioning holes 21 are equally spaced along the second direction Y on the fixing member 2.

[0055] Optionally, referring to Figure 1 and Figure 2 , a positioning member 3 is further included. The positioning member 3 is inserted through the first positioning hole 112 and the second positioning hole 21, and the positioning member 3 is provided with a mounting hole 31 for connecting with an external carrier.

[0056] Specifically, the positioning member 3 is composed of a main body and a locking member. The main body can be understood as a bolt, and the locking member can be understood as a nut. However, the connection manner between the main body and the locking member is not limited to threaded connection, and can also adopt clamping or plugging methods.

The mounting hole 31 can be a through hole penetrating the positioning member 3 or a blind hole. The mounting hole 31 is provided with internal threads, so that the battery pack can be fixed to an external carrier by means of bolts. For example, when the battery pack is fixed to a vehicle body, the external carrier is the vehicle body at this time. When the mounting hole 31 is a blind hole, one end of the bolt passes through the vehicle body and extends into the mounting hole 31, so that the battery pack and the vehicle body are threadedly connected as a whole by means of the bolt. When the mounting hole 31 is a through hole, one end of the bolt can pass through the mounting hole 31 and then be threadedly connected to the vehicle body.

[0058] Optionally, referring to Figures 1-3 , the support member 1 includes a support plate 12 and end plates 13.

When multiple battery cells 7 are placed on the support plate 12, the battery cells 7 close to the second connection portion 11 are in contact with the end plates 13, so that the end plates 13 play a role in clamping and limiting the battery cells 7, and at the same time play a role in restricting the expansion of the battery cells 7.

[0060] Among them, the second connection portion 11 can be directly fixedly connected to the support plate 12, or directly fixedly connected to the end plates 13, or connected to the support plate 12 and the end plates 13 together.

The left support plate 121, the right support plate 122, and the bottom plate 123 are connected into one body by means of welding, snap connection, or integral casting.

[0065] In some other embodiments, under the condition that the overall strength and safety of the battery pack have met the design requirements, the bottom plate 123 can be cancelled, and the battery cells 7 are only bonded to the left support plate 121 and the right support plate 122, thereby reducing the weight of the battery pack and saving costs while.

[0066] It should be noted that when two adjacent support members 1 are detachably connected by a snap structure or bolts, the specific connection position is not limited to the edge of the end plate 13, and can also be set at the edge of the left support plate 121 or the right support plate 122, or relevant connection structures can be set at the edges of the end plate 13, the left support plate 121, and the right support plate 122 simultaneously.

At least part of the first connecting portion 14 is embedded in the connecting groove on the connecting member 4, and then bolts or pins are inserted into the through holes of the first connecting portion 14 and the connecting member 4, so as to connect two adjacent support members 1 into a whole, thereby improving the stability of the overall structure of the installation assembly. At the same time, the U-shaped structure plays a limiting role on the support member 1, reducing the probability of the support member 1 moving.

[0071] In some embodiments, connection grooves for partial embedding of the first connection portions 14 on the end plates 13 may be respectively provided at opposite ends of each connecting member 4; during connection, the first connection portions 14 on two adjacent end plates 13 are respectively embedded into the corresponding connection grooves, and then bolts or pin shafts are passed through the through holes of the first connection portions 14 and the connecting member 4, so as to connect two adjacent support members 1 into a whole.
