[0046] Figures 1 to 3 The battery box 10 in some embodiments of the present invention is shown. Figure 4 and Figure 5 The battery box 10 includes a box 1, a positioning device 2 and a limiting device 3.

[0047] It can be understood that the box 1 is used to store and install other components. The positioning device 2 is used to guide the battery module to slide into the box 1. The limiting device 3 is used to limit the battery module together with the positioning device 2, wherein the positioning device 2 and the limiting device 3 limit the battery module from different directions respectively.

[0048] like Figure 4 As shown, the box body 1 is provided with a receiving cavity 11 and an opening 12 which are interconnected. It can be understood that the receiving cavity 11 is used to receive the battery module and other components. The opening 12 is used to allow the battery module and other components to be placed in the receiving cavity 11.

[0049] like Figures 4 to 6 As shown, the positioning device 2 includes a plurality of positioning guide rails 21, each of which is used to guide the battery module 20 to slide from the opening 12 into the storage cavity 11, and each of the positioning guide rails 21 is arranged on the inner wall surface of the storage cavity 11, one end of each of the positioning guide rails 21 is connected to the opening 12, and the other end of each of the positioning guide rails 21 extends toward the bottom of the storage cavity 11.

[0050] It can be understood that the positioning rail 21 is in the shape of an elongated strip. The number of the positioning rails 21 is configured to be multiple, so that the positioning rails 21 can limit the position of the battery module from multiple different positions, thereby eliminating the tediousness of manually positioning the battery module. Since one end of each positioning rail 21 is connected to the opening 12, the battery module can be prevented from being stuck at the end of the positioning rail 21 during the process of placing the battery module from the opening 12 into the storage cavity 11. The other end of each positioning rail 21 extends to the bottom of the storage cavity 11, so that the battery module 20 can slide along the positioning rail 21 to the predetermined position at the bottom of the storage cavity 11, eliminating the tediousness of repeatedly aligning the installation position of the battery module during the process of hoisting the battery module.

[0051] like Figures 4 to 8 As shown, the limiting device 3 includes a limiting plate 31 and a fixing assembly 32 . The limiting plate 31 is detachably connected to each positioning rail 21 through the fixing assembly 32 , so that the limiting plate 31 and each positioning rail 21 together limit the battery module 20 in the storage cavity 11 .

[0052] It can be understood that the limiting plate 31 is used to limit the battery module together with the bottom of the storage cavity 11. The fixing assembly 32 is used to fix the limiting plate 31 on the positioning guide rail 21.

[0053] During the actual assembly process, the battery module 20 is placed into the storage cavity 11 from the opening 12, and the battery module 20 abuts against the positioning rail 21. Then, the battery module 20 slides into the storage cavity 11 along the length direction of the positioning rail 21. After the battery module 20 slides into the predetermined position in the storage cavity 11, the limiting plate 31 is installed on the positioning rail 21. The limiting plate 31, each positioning rail 21 and the inner wall surface of the storage cavity 11 can jointly limit the battery module 20, completing the positioning and installation of the battery module in the storage cavity 11. The tediousness of manually hoisting the battery module and repeatedly aligning and installing it is eliminated, and there is no need to manually disassemble the positioning rail 21, which greatly improves the assembly production efficiency of the product.

[0054] like Figures 4 to 8 As shown, in some embodiments of the battery box 10, the positioning device 2 further includes at least one positioning member 22 (the positioning member 22 is shown in FIG. Figure 5 , Figure 7 and Figure 8), the positioning member 22 is disposed in the storage cavity 11, and a guide surface 221 and a positioning surface 222 are provided on the positioning member 22, the guide surface 221 faces the opening 12, and the battery module 20 slides against the guide surface 221 when placed in the storage cavity 11, and the positioning surface 222 is used to limit the battery module 20.

[0055] It can be understood that the positioning member 22 is used to limit the battery module 20 from a direction different from the positioning guide rail 21. The guide surface 221 is tilted on the positioning member 22. When the battery module 20 is placed in the box 1, the battery module 20 will be supported on the guide surface 221, and along with the placement of the battery module 20, the battery module 20 will also slide along the guide surface 221, so that the battery module 20 is gradually aligned with the predetermined installation position under the limitation of the guide surface 221; then, the limitation in this direction is completed until the positioning surface 222 is aligned with the side of the battery module 20.

[0056] It should be noted that the positioning member 22 and the positioning rail 21 are preferably configured to limit the battery module 20 from different directions, thereby improving the positioning accuracy of the battery module 20 .

[0057] Furthermore, the arrangement positions of the positioning rail 21 and the positioning member 22 have at least the following embodiments:

[0058] First, on two opposite side surfaces in the storage cavity 11 , a positioning guide rail 21 is disposed on one side surface, and a positioning member 22 is disposed on the other side surface.

[0059] It can be understood that in the process of placing the battery module 20 in the receiving cavity 11 , the battery module 20 will be confined between the positioning rail 21 and the positioning member 22 .

[0060] Secondly, on two adjacent side surfaces in the storage cavity 11 , only the positioning guide rail 21 is disposed on one of the side surfaces, and only the positioning member 22 is disposed on the other side surface.

[0061] It can be understood that after the battery module 20 is assembled into the storage cavity 11, the positioning guide rail 21 and the positioning member 22 will jointly support and limit the two adjacent side surfaces of the battery module 20, that is, one of the corner positions of the battery module 20 is limited, so that the other corresponding corner position on the battery module 20 is correspondingly supported on the inner wall surface of the storage cavity 11, thereby completing the limited installation of the battery module 20.

[0062] Thirdly, there are two groups of side surfaces in the storage chamber 11, and each group of side surfaces includes two opposite side surfaces. On one group of side surfaces, each side surface is provided with a positioning guide rail 21, and on the other group of side surfaces, each side surface is provided with a positioning member 22.

[0063] It can be understood that during the assembly process, the positioning rails 21 on the two sides allow the battery module 20 to be slidably installed in the storage cavity 11, and on the other hand, once the battery module 20 is placed in the storage cavity 11, two opposite sides of the battery module 20 will be limited by the positioning rails 21. As the installation depth of the battery module 20 continues to increase, the other two opposite sides of the battery module 20 will be guided and aligned by the positioning member 22, so that at least four non-overlapping sides of the battery module 20 are limited, that is, the battery module 20 will be limited in two mutually intersecting directions, thereby accurately positioning the assembly position of the battery module 20.

[0064] like Figure 5 , Figure 7 and Figure 8 As shown, in some embodiments of the battery box 10, the positioning device 2 includes a plurality of positioning members 22, each positioning member 22 is symmetrically arranged on the inner wall surface of the storage cavity 11, and each positioning guide rail 21 is symmetrically arranged on the inner wall surface of the storage cavity 11;

[0065] Each positioning rail 21 corresponds to two opposite side surfaces of the battery module 20 , and each positioning member 22 corresponds to the other two opposite side surfaces of the battery module 20 .

[0066] It can be understood that the number of positioning members 22 is configured to be multiple, and the symmetrically arranged positioning members 22 can guide the battery module 20 to gradually align the spacing positions between the positioning members 22 during the installation process, so that the battery module 20 falls into the spacing between the positioning members 22; correspondingly, the symmetrically arranged positioning rails 21 can guide the battery module 20 to fall into the spacing between the positioning rails 21.

[0067] Furthermore, since two of the opposite sides of the battery module 20 are limited by the positioning rails 21, the other two opposite sides of the battery module 20 are limited by the positioning members 22. Therefore, each positioning rail 21 and each positioning member 22 can limit the battery module 20 from two mutually intersecting directions, respectively, so that the battery module 20 can be accurately limited in the horizontal direction. Combined with the limiting plate 31 and the limiting of the bottom of the storage cavity 11 in the vertical direction, the battery module 20 can be accurately and reliably limited in both the horizontal and vertical directions, so that the battery module 20 can automatically complete the alignment installation during the process of being installed in the box body 1, which greatly improves the product assembly production efficiency while ensuring the high installation positioning accuracy of the battery module.

[0068] like Figures 1 to 8 As shown, in some embodiments of the battery box 10, at least one positioning member 22 includes a positioning cover 23, the positioning cover 23 is disposed on the inner wall surface of the storage cavity 11, and the positioning cover 23 is provided with a guide surface 221 and a positioning surface 222 (see Figure 8 );

[0069] The box body 1 is provided with an avoidance hole 13 communicating with the storage chamber 11 . The positioning cover 23 is disposed on the avoidance hole 13 . The guide surface 221 is provided with a connector 223 . The connector 223 is exposed in the avoidance hole 13 .

[0070] It can be understood that the positioning cover 23 is a cover-shaped structure with an opening. The positioning cover 23 is provided with a guide surface 221 at a position adjacent to the opening 12 . The positioning cover 23 is provided with a positioning surface 222 at a position for limiting the battery module 20 .

[0071] It should be noted that, since the guide surface 221 is inclined, the connector 223 disposed on the guide surface 221 will also be inclined on the box body 1, that is, the connection direction of the connector 223 is inclined outward. In this way, when an external connector needs to be connected to the connector 223 of this product, the connector can be inserted in an inclined position. Compared with a connector disposed vertically upward or vertically downward, the connector 223 of this product is easier to connect and use.

[0072] like Figure 4 and Figure 5 As shown, in some embodiments of the battery box 10 , the box 1 is bent inward at the opening 12 to form an inner fold 15 , and the inner fold 15 covers the ends of each positioning guide rail 21 .

[0073] It can be understood that the setting of the inner fold 15 can prevent the fold from protruding outside the box body 1 and prevent the fold from affecting the surface flatness of the box body 1. The inner fold 15 shields the ends of each positioning rail 21, which can prevent the ends of the positioning rail 21 from protruding into the opening 12, thereby preventing the ends of the positioning rail 21 from blocking the insertion of the battery module 20, so that the assembly process only needs to align the battery module 20 with the opening 12.

[0074] In some embodiments, the positioning rail 21 may be configured to be U-shaped or L-shaped, or configured to be other long structures in the prior art that can be applied to the box.

[0075] like Figure 5 and Figure 6 As shown, in some embodiments of the battery box 10, the fixing assembly 32 includes a plurality of fixing connection holes, a plurality of fixing parts 321 and a plurality of fixing connection parts 322, each fixing connection hole is respectively arranged on each positioning guide rail 21, each fixing connection part 322 passes through the fixing part 321 and the limiting plate 31, and each fixing connection part 322 passes through and is fixed in the fixing connection hole.

[0076] It can be understood that the fixed connection hole is used for the fixed connection member 322 to pass through and be fixed, and the fixing member 321 is used to be pressed on the limiting plate 31 when the fixed connection member 322 is fixed, so as to complete the fixation of the connection member 322.

[0077] like Figures 5 to 8 As shown, in some embodiments of the battery box 10 , a fixed bending edge 311 and a limiting bending edge 312 are provided on the limiting plate 31 , the fixing member 321 and the fixed bending edge 311 support each other, and the limiting bending edge 312 is used to limit the battery module 20 .

[0078] It can be understood that the limiting plate 31 is used to limit the battery module 20 on the one hand, and can also be configured to fix other electronic components and wiring harnesses on the other hand. The fixed bent edge 311 is used to adapt to the fixed component 32, and the specific adaptation method includes fitting on the outer contour after adaptation, plug-in matching and / or other matching methods in the prior art. The fixed bent edge 311 is matched with the limiting plate 31 at an angle. The limiting bent edge 312 is used to limit the battery module 20.

[0079] It should be noted that the fixed bending edge 311 and the limiting bending edge 312 can be configured to be bent in different directions relative to the limiting plate 31, so that during assembly, the limiting plate 31 can be installed and fixed from one side of the limiting plate 31, and the battery module 20 can be limited by the limiting bending edge 312 on the other side of the limiting plate 31.

[0080] Specifically, in some embodiments of the battery case 10 , the fixing connection member 322 includes a bolt, and the bolt is threadedly connected to the fixing connection hole.

[0081] It can be understood that the bolts are used to connect and pass through the fixed connecting piece 322 and the fixed bent edge 311 , and then the bolts are screwed onto the positioning guide rail 21 to complete the fixation of the limiting plate 31 .

[0082] like Figure 6 As shown, in some embodiments of the battery case 10, the fixing connection member 322 includes a bolt and a nut, and the bolt passes through the fixing connection hole and is threadedly connected to the nut.

[0083] It can be understood that the fixing of the limiting plate 31 can be completed by passing the bolts through the fixed connecting piece 322, the fixed bent edge 311 and the positioning guide rail 21, and then screwing the nuts and the bolts together.

[0084] Figures 1 to 8 The battery box 10a in some embodiments of the utility model is shown. The battery box 10a includes a battery box body 1 and a battery module 20. The battery box 10a also includes a circuit board 70 (the circuit board 70 is shown in FIG. Figures 4 to 8 );

[0085] The battery module 20 includes a plurality of single batteries. The battery module 20 is disposed in the storage cavity 11 . The lower surface of the limiting plate 31 faces the battery module 20 . The circuit board 70 is disposed on the upper surface of the limiting plate 31 .

[0086] It can be understood that the battery box 10a has charging and discharging functions and can be applied to various fields of electrical energy storage. The battery box 1 is used to accommodate the battery module 20. The battery module 20 is composed of a plurality of elastic batteries connected together. The number of single cells in the battery module 20 can be flexibly set and flexibly adjusted according to the application requirements; of course, with the number and arrangement of single cells contained in the battery module 20, the external specifications of the battery module 20 will also be different. Furthermore, the inner wall contour of the storage cavity 11 and the specifications of the corresponding components involved in the battery module limit will also be adjusted accordingly, so that battery modules 20 of various specifications can be reliably fixed.

[0087] It should be noted that the lower surface of the limiting plate 31 is used to limit the battery module 20 in the longitudinal direction together with the bottom of the storage cavity 11, and the inner wall surface of the storage cavity 11 and the positioning device 2 are used to limit the battery module 20 from the circumferential direction, thereby effectively limiting the battery module 20 together.

[0088] like Figure 5 and Figure 8 As shown, in some embodiments of the battery box 10a, the battery box 10a further includes an isolation mechanism 30, the isolation mechanism 30 includes a plurality of isolation plates 50 and a plurality of buffer cottons 60, each isolation plate 50 is supported on each side of the battery module 20 in a one-to-one correspondence, and a buffer cotton 60 is provided between at least part of the isolation plates 50 and the battery module 20; and / or

[0089] The battery box 10 a further includes a plurality of foot pads 40 . A plurality of mounting grooves 14 are disposed at the bottom of the box body 1 , and a foot pad 40 is disposed in each mounting groove 14 .

[0090] It can be understood that the isolation mechanism 30 is used to provide buffer protection on each outer side of the battery module 20, and is also used to fill the gap between the battery module 20 and the corresponding limiting structure to prevent the battery module 20 from shaking in the storage cavity 11 as much as possible. The isolation plate 50 is used to isolate and protect the battery module 20. The buffer cotton 60 is used to buffer the impact force applied to the battery module 20. The foot pad 40 is used to support the box body 1 from the bottom to prevent slipping and prevent direct wear of the box body 1.
