The present application is described in further detail below with reference to specific embodiments and with reference to the attached drawings.
Referring to fig. 1 to 8, the battery pack of the present application includes a temperature control assembly 1, a plurality of batteries 2, a lower case 3, an air duct assembly 4, a fan 5, a strap 6, an upper case cover 7, an end plate 8, a mounting panel 9, and a harness isolation plate 10.
Referring to fig. 1 and 2, the plurality of batteries 2 include a first battery 2A and a second battery 2B, and the temperature control assembly 1 is disposed between the first battery 2A and the second battery 2B. Further, the first battery 2A and the second battery 2B may be both plural in number, the plural first batteries 2A and the plural second batteries 2B are alternately arranged in the longitudinal direction Y, and the temperature control assembly 1 may be disposed between each adjacent first battery 2A and second battery 2B.
In order to ensure the strength and thermal conductivity of the temperature control assembly 1, the temperature control assembly 1 may be made of a metal material, such as an aluminum profile.
Referring to fig. 3 to 8, the temperature control assembly 1 may include a first side plate 11, a second side plate 12, a first buffer plate 13, a first connection plate 15, and a second connection plate 16. The first side plate 11, the second side plate 12, the first buffer plate 13, the first connecting plate 15 and the second connecting plate 16 may be integrally formed by an aluminum extrusion process.
The first side plate 11 is disposed opposite to the second side plate 12 in the longitudinal direction Y, and the second side plate 12 is connected to the first side plate 11 by a first connecting plate 15 and a second connecting plate 16. The first side plate 11 and the second side plate 12 are directly arranged facing the large surface of the corresponding battery 2, and when external air flows through the temperature control assembly 1, heat dissipation treatment of the battery 2 can be achieved.
The first connecting plate 15 connects one end of the first side plate 11 and one end of the second side plate 12, and the second connecting plate 16 connects the other end of the first side plate 11 and the other end of the second side plate 12, so that the first side plate 11, the second side plate 12, the first connecting plate 15 and the second connecting plate 16 together form an enclosure frame structure with a cavity.
The first buffer board 13 is disposed between the second side board 12 and the first side board 11 and connected to the second side board 12 and the first side board 11 to divide the cavity into a plurality of channels F, and at least a portion of the first buffer board 13 extends from the first side board 1 toward the second side board 12 in an inclined manner. The number of the first buffer plates 13 may be plural, and the plural first buffer plates 13 are arranged at intervals in the up-down direction Z, so that the cavity is divided into plural channels F.
During the use of the battery pack, the batteries 2 generate an expansion force, at this time, the expansion force of two adjacent batteries 2 (i.e. the first battery 2A and the second battery 2B) respectively presses the first side plate 11 and the second side plate 12, and the first side plate 11 and the second side plate 12 transmit the expansion force to the first buffer plate 13. Since at least a part of the first buffer plate 13 extends obliquely from the first side plate 1 toward the second side plate 12, the expansion force transmitted to the first buffer plate 13 via the first side plate 11 and the second side plate 12 is greatly reduced, thereby prolonging the service life of the temperature control assembly 1. Moreover, at least the part of the first buffer plate 13 extending obliquely is more easily bent and deformed under the action of the expansion force, so that the temperature control assembly 1 can absorb the expansion force of the battery 2 in time, and the service life of the battery 2 is greatly prolonged.
Because the extension direction of first buffer board 13 (being first buffer board 13 at least partial extension direction) and the contained angle size that first curb plate 11 formed and the contained angle size that second curb plate 12 formed, decided the expansion force size that transmits for first buffer board 13 via first curb plate 11 and second curb plate 12, if the expansion force that first buffer board 13 received is too big, then can press first buffer board 13 absolutely. Therefore, in order to prevent the first cushioning plate 13 from being crushed by an excessive expansion force, it is preferable that, referring to fig. 8, an acute angle θ formed by the extending direction of the first cushioning plate 13 and the first side plate 111Not more than 45 ° (the acute angle formed by the first buffer plate 13 and the second side plate 12 is equal to the acute angle formed by the first buffer plate 13 and the first side plate 11).
Several specific structures of the temperature control unit 1 will be described in detail based on the arrangement of the first buffer plate 13.

In the second embodiment, referring to fig. 3 and 4, only the first buffer plate 13 is disposed between the first side plate 1 and the second side plate 12 of the temperature control assembly 1, and at this time, the first buffer plate 13 may be formed into a wave-like structure (also referred to as a corrugated plate-like structure). In other words, the first buffer plates 13 extend alternately in a direction obliquely upward from the first side plate 11 toward the second side plate 12 and in a direction obliquely downward from the first side plate 11 toward the second side plate 12.
The first buffer plate 13 of this structure is formed with protrusions one by one, and each protrusion is formed in an arc-shaped structure.

The second buffer plates 14 may be plural in number, and the plural second buffer plates 14 are arranged at intervals in the up-down direction Z to divide the cavity into the plural passages F together with the first buffer plate 13.
Due to the extending direction of the second buffer plate 14 and the first buffer plateThe size of the included angle formed by the side plate 11 and the size of the included angle formed by the side plate 12 determine the expansion force transmitted to the second buffer plate 14 through the first side plate 11 and the second side plate 12, and if the expansion force received by the second buffer plate 14 is too large, the second buffer plate 14 is broken. Therefore, in order to prevent the second cushioning plate 14 from being crushed by an excessive expansion force, it is preferable that, referring to fig. 8, an acute angle θ formed by the extending direction of the second cushioning plate 14 and the first side plate 112Not more than 45 ° (the acute angle formed by the second dash panel 14 and the second side panel 12 is equal to the acute angle formed by the second dash panel 14 and the first side panel 11).
Referring to fig. 5, the second buffer plate 14 is spaced from the first buffer plate 13 along the up-down direction Z, and the first buffer plate 13 and the second buffer plate 14 are arranged in a staggered manner, so that the first buffer plate 13 and the second buffer plate 14 are formed into a structure of a "eight" shape. The structure stability of the temperature control assembly 1 is ensured and the structural strength of the temperature control assembly 1 is improved due to the splayed structure.
Referring to fig. 6, the second buffer board 14 is directly connected to the first buffer board 13, and the first buffer board 13 and the second buffer board 14 form a triangle structure with the corresponding portion of the first side board 1, and the first buffer board 13 and the second buffer board 14 also form a triangle structure with the corresponding portion of the second side board 12. The triangular structure ensures the structural stability of the temperature control component 1 and improves the structural strength of the temperature control component 1.
Referring to fig. 7, the second buffer plate 14 is directly connected to the first buffer plate 13, and the first buffer plate 13 and the second buffer plate 14 are formed in an arch structure. The arched structure ensures the structural stability of the temperature control component 1 and improves the structural strength of the temperature control component 1.
In the third embodiment, the first buffer plate 13 and the second buffer plate 14 may be formed in a structure having a uniform thickness (as shown in fig. 6 and 7). Alternatively, the first buffer plate 13 and the second buffer plate 14 may be formed in a structure in which the middle is thick and both ends are thin. Alternatively, the first buffer plate 13 and the second buffer plate 14 may be formed in a structure (as shown in fig. 5 and 8) which is thin in the middle and thick at both ends. The first and second buffer plates 13 and 14 may be formed in a plate-shaped structure (as shown in fig. 6) or an arc-shaped structure (as shown in fig. 7).

Wherein, the height of the air volume adjusting plate 41 is reduced along the direction from the first supporting plate 42 to the second supporting plate 43 in order to expand the air duct along the longitudinal direction Y from the side close to the fan 5 to the side far from the fan 5.
The mounting plate 44 extends in the longitudinal direction Y and is connected to the first support plate 42 and the second support plate 43, and the air volume adjusting plate 41 is fixedly mounted to the mounting plate 44. The seal strips 45 are provided on the first support plate 42, the second support plate 43, and the mounting plate 44.
