[0034] The following will describe in detail the detailed implementation manners of the present disclosure with reference to the accompanying drawings. It should be understood that the detailed implementation manners described herein are only for explaining and illustrating the present disclosure, and are not used to limit the present disclosure.

[0035] In the present disclosure, unless otherwise stated, the orientation terms such as "inside, outside" refer to "inside, outside" relative to the self-profile of the corresponding component, "top, bottom" refer to "top, bottom" in the height direction in the use state of the present disclosure, the "first direction" refers to the length direction of the outer shell, and the "second direction" refers to the width direction of the outer shell.

In addition, in the following description, when referring to the accompanying drawings, unless otherwise explained, the same reference numerals in different drawings represent the same or similar elements. The above definitions are only for explaining and illustrating the present disclosure, and should not be construed as a limitation to the present disclosure.

[0036] According to a first aspect of the present disclosure, there is provided a battery housing, as shown in Figure 1 、 Figure 2 、 Figure 6 and Figure 7 , the battery housing includes an outer shell 1 and a support assembly 2. The outer shell 1 includes a first housing 11 and a second housing 12. The second housing 12 forms an accommodation space with an opening on one side. The first housing 11 is covered at the opening and connected to the second housing 12. The first housing 11 is provided with terminal mounting parts 111 at both ends in the first direction. The second housing 12 includes two first side walls arranged opposite to each other in the second direction. The support assembly 2 is disposed in the accommodation space and includes two first support members 22. The two first support members 22 are respectively attached to the two first side walls. Among them, the first direction intersects with the second direction.

[0037] Through the above technical solution, in the battery housing provided in the present disclosure, the second housing 12 forms a receiving space with an opening on one side, the first housing 11 is covered at the opening of the second housing 12, and the support assembly 2 is disposed in the receiving space. In this way, the support assembly 2 can be disposed between the first housing 11 and the second housing 12 to support the first housing 11 and the second housing 12. In addition, the support assembly 2 includes two first support members 22, and the two first support members 22 are attached to the two first side walls of the second housing 12. In this way, the two first support members 22 can respectively support the corresponding first side walls. In summary, the support assembly 2 can support the outer shell 1 to improve the structural strength of the battery outer shell 1.

[0038] In addition, the connection between the terminal assembly and the first housing 11 can be realized through the terminal mounting portion 111 to simplify the parts (such as the cover plate) of the battery.

[0039] In the battery housing provided in the present disclosure, the support assembly 2 can be constructed in any suitable manner. As an exemplary embodiment, referring to Figure 2 as shown in, the second housing 12 further includes two second side walls opposite to each other in the first direction, the support assembly 2 further includes two second support members 21, the two second support members 21 are respectively attached to the two second side walls, and the two ends of the second support member 21 in the second direction are respectively connected to the two first support members 22. In this way, the two second support members can respectively support the corresponding second side walls, that is to say, the support assembly 2 can support the entire circumference of the side walls of the second housing 12. In addition, the two ends of the second support member 21 in the second direction are respectively connected to the two first support members 22. In this way, only the first support member 22 and the second support member 21 need to be processed separately, and then the first support member 22 and the second support member 21 are assembled together, which can reduce the processing difficulty.

[0040] In another exemplary embodiment, the support assembly 2 can also be constructed as two L-shaped support members. Among them, the two sides of each L-shaped support member are respectively attached to the first side wall and the second side wall, and the two L-shaped support members are detachably connected. Among them, the connection points of the two L-shaped support members are respectively located at both ends of the diagonal of the second housing 12. In this way, the number of support members can be reduced to simplify the assembly steps of each support member and save assembly time. In other embodiments, the support assembly 2 can also be constructed in other suitable ways, and the present disclosure does not make specific restrictions on this.

[0041] In the battery housing provided in the present disclosure, in order to facilitate the assembly of the support assembly 2, referring to Figure 6 and Figure 7As shown, the second housing 12 may include a protrusion 122 that protrudes away from the accommodation space to form a receiving space, and the first support member 22 and the second support member 21 may be respectively disposed in the corresponding receiving spaces. In this way, the first support member 22 and the second support member 21 can be placed between the top wall and the bottom wall of the protrusion 122 and are arranged along the side wall of the second housing 12, so as to ensure that the support assembly 2 does not occupy the layout space of the battery cell 3. The battery cell 3 may be disposed on one side of the support assembly 2 close to the accommodation space, that is, the first support member 22 and the second support member 21 may surround the battery cell 3 in a circle.

[0042] In the battery housing provided by the present disclosure, in order to facilitate the connection between the first housing 11 and the second housing 12, as an exemplary embodiment, with reference to Figure 1 , Figure 2 and Figure 6 As shown, the second housing 12 may include a connecting portion 121 and a connecting flange 123. The connecting portion 121 connects the protrusion 122 and the connecting flange 123. The connecting flange 123 may be bent from the connecting portion 121 and extend away from the accommodation space. The first housing 11 may be connected to the connecting flange 123. In this way, the connecting flange 123 can increase the contact area between the second housing 12 and the first housing 11. The connecting portion 121 may be arranged close to the first housing 11. In this way, the second housing 12 can connect the first housing 11 through the connecting flange 123 to improve the connection reliability between the first housing 11 and the second housing 12.

[0043] In this embodiment, the connecting flange 123 may be flush with the outer wall surface of the protrusion 122. In this way, it is possible to prevent the connecting flange 123 from protruding from the side wall of the second housing 12 to save the layout space of the second housing 12. In other embodiments, the connecting flange 123 may also not extend beyond the outer wall surface of the protrusion 122, and the present disclosure does not make specific limitations thereto.

[0044] In the present disclosure, the first housing 11 and the connecting flange 123 may be connected in any suitable manner. As an exemplary embodiment, the first housing 11 and the connecting flange 123 may be laser welded. Specifically, after the first housing 11 and the connecting flange 123 are overlapped, a laser can be used to penetrate the connecting flange 123 from the first housing 11 to weld the two together to seal the outer shell 1.

[0045] Wherein, with reference to Figure 7As shown, the width of the connecting portion 121 is a, and the depth is b. In this way, when a is smaller, the projected size of the support assembly 2 on the side wall of the second housing 12 is larger, and the support effect of the support assembly 2 is better; when b is larger, the projected size of the support assembly 2 on the first housing 11 is larger, and the support effect of the support assembly 2 is better. However, reducing a will increase the difficulty of connecting the first housing 11 and the second housing 12, and reducing b will reduce the layout space of the battery cell 3. Therefore, the first width a and the first depth b can be appropriately selected according to actual needs, and the present disclosure does not make specific restrictions thereon.

[0046] Wherein, the second support member 21 can be detachably connected to the first support member 22. In the battery housing provided by the present disclosure, the detachable connection between the second support member 21 and the first support member 22 can be achieved in any suitable manner. As an exemplary embodiment, refer to Figures 3 to 5 As shown, the second support member 21 and the first support member 22 can be connected by a snap-fit structure. The snap-fit structure can include a cooperating snap 221 and a slot 211. One of the second support member 21 and the first support member 22 can be formed with the snap 221, and the other can be formed with the slot 211. The snap 221 can be snap-fitted into the slot 211. In this way, when installing the first support member 22 and the second support member 21, only snap-fitting is required, and the operation is simple.

[0047] In this embodiment, the snap 221 can be formed on the first support member 22, and the slot 211 can be formed on the second support member 21. In other embodiments, the snap 221 can be formed on the second support member 21, and the slot 211 can be formed on the first support member 22. The present disclosure does not make specific restrictions thereon. Among them, the snap 221 and the slot 211 can be constructed in any suitable manner, such as semi-circular, wedge-shaped, etc. The present disclosure does not make specific restrictions thereon. In other embodiments, the first support member 22 and the second support member 21 can also be detachably connected in other suitable ways, and the present disclosure does not make specific restrictions thereon.

[0048] In the battery housing provided by the present disclosure, for the convenience of assembly, as an exemplary embodiment, refer to Figure 1 and Figure 2 As shown, the second housing 12 can be formed with a terminal receiving portion 4. The second side wall can be recessed toward the receiving space to form the terminal receiving portion 4. In this way, when the batteries are grouped, the terminal receiving portion 4 can be used to receive the terminal assembly of the battery adjacent to the current battery, so as to improve the space utilization rate after the batteries are grouped.

[0049] In the battery housing provided by the present disclosure, the second support member 21 can be constructed in any suitable manner. As an exemplary embodiment, refer to Figure 3As shown in the figure, the second support member 21 may include a plate body, and the plate body may include a first plate 213, a second plate 212, and a third plate 214. The first plate 213 may be attached to the second side wall, and the second plate 212 and the third plate 214 may be respectively connected to both ends of the first plate 213 and extend toward the first side wall. The second plate 212 and the third plate 214 are respectively used to connect to the first support member 22. Among them, the first plate 213 is arranged in contact with the second side wall, which can ensure the supporting effect of the first plate 213 on the second side wall and the first housing 11 and the second housing 12 located at both ends of the second side wall.

[0050] In addition, the second plate 212 and the third plate 214 extend toward the first side wall. That is to say, the second support member 21 is completely attached to the second side wall and partially attached to the first side wall connected to the second side wall. In this way, the second support member 21 can support the connection between the first side wall and the second side wall to strengthen the structural strength of the connection between the first side wall and the second side wall. In summary, the arrangement of the second plate 212 and the third plate 214 not only facilitates the connection between the second support member 21 and the first support member 22, but also enables the connection point between the second support member 21 and the first support member 22 to be staggered from the connection between the first side wall and the second side wall. Compared with arranging the connection point between the second support member 21 and the first support member 22 at the connection between the first side wall and the second side wall, the above-mentioned staggered arrangement can improve the support effect of the support assembly 2 on the connection between the first side wall and the second side wall.

[0051] In the battery housing provided by the present disclosure, the first plate 213 may be constructed in any suitable manner. As an exemplary embodiment, referring to Figure 1 、 Figure 2 and Figure 7 As shown in the figure, the first plate 213 may include a first plate segment 2131, a second plate segment 2132, and a third plate segment 2133. The second plate segment 2132 may be connected between the first plate segment 2131 and the third plate segment 2133 and is arranged at a first angle and a second angle with the first plate segment 2131 and the third plate segment 2133 respectively. The second angle may be greater than the first angle. In this way, the arrangement of the first plate segment 2131, the second plate segment 2132, and the third plate segment 2133 can make the first plate 213 fit the second side wall to ensure the supporting effect of the first plate 213 on the second side wall.

[0052] In addition, the setting that the second included angle is greater than the first included angle enables the pole column accommodating portion 4 to be adapted to the terminal assembly. In this embodiment, the first included angle can be configured as a right angle, and the second included angle can be configured as an obtuse angle. Compared with setting the first included angle and / or the second included angle as an acute angle, the above setting can improve the structural strength of the housing 1 and prevent the housing 1 from deforming under external force. In other embodiments, the first included angle and the second included angle can also be configured as other suitable angles, and the present disclosure does not make specific limitations thereto.

[0053] In the battery housing provided by the present disclosure, in order to further improve the structural strength of the second support member 21, as an exemplary embodiment, referring to Figure 3 as shown in, the second support member 21 can be provided with a reinforcing structure, and the reinforcing structure can include a first reinforcing rib 215 and a second reinforcing rib 216. The first reinforcing rib 215 and the second reinforcing rib 216 can be arranged in a cross shape and are both connected to the plate body. In this way, the first reinforcing rib 215 and the second reinforcing rib 216 not only ensure the improvement of the structural strength of the second support member 21, but also can reduce the weight of the second support member 21, which is beneficial to the lightweight of the battery.

[0054] Among them, the reinforcing structure can be provided in two groups, and an avoidance space 217 can be formed between the two groups of reinforcing structures for avoiding the pole ear adapter connected to the battery cell 3. In this way, on the basis of ensuring the supporting effect of the second support member 21, the reinforcing structure can be prevented from colliding with the pole ear adapter.

[0055] In the battery housing provided by the present disclosure, the first support member 22 can be constructed in any suitable manner. As an exemplary embodiment, referring to Figures 4 to 6 as shown in, the first support member 22 can be constructed as a plate shape and is provided with a plurality of ventilation holes 223, and the plurality of ventilation holes 223 can be arranged at intervals. In this way, when the battery undergoes thermal runaway, the setting of the ventilation holes 223 can facilitate the discharge of the gas inside the housing 1, and prevent the battery from exploding due to excessive pressure inside the housing 1.

[0056] It should be noted that, among them, the second support member 21 can be arranged along the width direction of the battery, and the first support member 22 can be arranged along the length direction of the battery. In this way, it can be ensured that the plurality of ventilation holes 223 are also arranged along the length direction of the battery to increase the area for discharging the gas inside the housing 1, which is beneficial to the rapid discharge of the gas inside the housing 1.

[0057] In the battery housing provided by the present disclosure, in order to further improve the structural strength of the first support member 22, as an exemplary embodiment, referring to Figures 4 to 6As shown in the figure, the first support member 22 may include a main body and be provided with a third reinforcing rib 222. The third reinforcing rib 222 may be disposed on a side of the main body facing the first side wall and be in contact with the first side wall. An exhaust passage may be formed between the main body and the first side wall. The exhaust passage may communicate with the accommodation space through a vent hole 223. In this way, on the one hand, the support effect of the first support member 22 can be ensured, and at the same time, the weight of the first support member 22 can be reduced, which is beneficial to the lightweight of the battery; on the other hand, the internal gas can enter the exhaust passage through the vent hole 223 to ensure that the gas can be effectively discharged from the housing 1.

[0058] According to a second aspect of the present disclosure, there is provided a battery, which includes the above battery housing.

[0059] According to a third aspect of the present disclosure, there is provided a battery pack, which includes the above battery.
