[0029] like Figure 1 and Figure 2 As shown, this embodiment of the utility model provides a battery box 1, including a box body 11, a power interface 12, and a shielding member 13. The box body 11 is hollow inside to form a receiving cavity 111. The box body 11 has multiple side walls 112, and at least one side wall 112 is provided with an installation space 113. The power interface 12 is opened on the side wall 112 with the installation space 113, and is located within at least one installation space 113. The power interface 12 communicates with the receiving cavity 111. The shielding member 13 is connected to the box body 11 to cover each installation space 113. A gap 114 is formed between the shielding member 13 and the side wall 112 with the installation space 113.

[0030] Specifically, the receiving cavity 111 formed by the housing 11 is at least used for installing batteries. Depending on the design, other components such as a circuit board carrying a BMS (Battery Management System) may also be installed in the receiving cavity 111. Optionally, the battery box 1 can be an empty box without batteries, and batteries are installed in the receiving cavity 111 according to actual usage needs; the battery box 1 can also be pre-installed with batteries for direct use by the user. The installation space 113 provided on the side wall 112 of the housing 11 can be understood as the area formed on the side wall 112. The specific arrangement of the installation space 113 is described in detail in the following embodiments. Optionally, one or more installation spaces 113 can be provided. When multiple installation spaces 113 are provided, each installation space 113 can be provided on the same side wall 112 or on different side walls 112.

[0031] Specifically, the power supply interface 12 is in communication with the accommodating cavity 111 for connecting the load with the battery installed in the accommodating cavity 111, and the form of the power supply interface 12 can be designed flexibly as required, as long as the connection of the load and the battery can be adapted. Optionally, the number of the power supply interface 12 can be one or more, and when the power supply interface 12 is provided with a plurality of power supply interfaces 12, each power supply interface 12 can be located in the same mounting space 113 or in different mounting spaces 113.

[0032] Specifically, the mounting space 113 provided on the side wall 112 can be directly exposed first, so that the parts arranged in the mounting space 113 are not blocked by other objects when being installed or externally connected, and the operation is convenient. At the same time, when a plurality of battery boxes 1 of the same structure are stacked and connected, components for connecting and fixing adjacent battery boxes 1 can be arranged in the mounting space 113 to perform the connecting and fixing operation between the battery boxes 1, the stacking and connecting operation between the battery boxes 1 is convenient, and the mounting space 113 can be fully utilized, and the structure is compact.

[0033] The shielding piece 13 provided in the embodiment of the utility model is used for covering each mounting space 113, and the position and number of the shielding piece 13 can be determined according to the mounting space 113. For example, when the mounting space 113 is provided with a plurality of mounting spaces 113, and the relative positions between the mounting spaces 113 are relatively close, the shielding piece 13 can be provided with only one shielding piece 13, and all the mounting spaces 113 can be covered by one shielding piece 13; when the relative positions between the mounting spaces 113 are relatively far apart, for example, located on opposite sides of the box body 11 respectively, the shielding piece 13 can be provided with a plurality of shielding pieces 13, and each shielding piece 13 covers different mounting spaces 113; or each mounting space 113 can be uniformly covered by one large shielding piece 13.

[0034] For the connection mode of the shielding piece 13 and the box body 11, the shielding piece 13 can be directly connected with the side wall 112, can be connected to other positions of the box body 11, or can be indirectly connected with the box body 11 through other connecting components, as long as the purpose of covering the mounting space 113 can be achieved. Through the design of covering the mounting space 113 by the shielding piece 13, the power supply interface 12 is not easily visible from the appearance, so that the overall appearance of the battery box 1 presents a relatively complete structure, and the appearance is better, and the shielding piece 13 can at least block a part of the interference of the external environment in the direction of covering the power supply interface 12, and has a certain protection effect on the power supply interface 12, and the reliability of the battery box 1 can be improved.

[0035] It should be noted that the shielding piece 13 does not completely block the installation space 113, and a gap 114 is formed between the shielding piece 13 and the side wall 112 in which the installation space 113 is formed, which can pass the cable connected between the load and the power interface 12. Specifically, the installation space 113 and the shielding piece 13 can be designed in shapes such that the gap 114 is formed when the shielding piece 13 covers the installation space 113. For example, as shown in Figure 2 the installation space 113 is recessed on the side wall 112, the shielding piece 13 can be provided in a plate shape. Of course, the shielding piece 13 can also be provided in a shape protruding away from the installation space 113, so that the protruding part forms the gap 114 with the side wall 112 in which the installation space 113 is formed. By such design, the shielding piece 13 can cover the installation space 113, and the gap 114 formed between the shielding piece 13 and the side wall 112 can meet the connection of the battery box 1 and the load, so as to improve the overall appearance of the battery box 1 while not affecting the normal use of the battery box 1, and make the battery box 1 have both appearance and practicability.

[0036] The battery box 1 provided by the embodiment of the utility model, including box body 11, power interface 12 and shielding piece 13, at least one side wall 112 of box body 11 is provided with installation space 113, and power interface 12 is arranged in installation space 113. By covering the installation space 113 with the shielding piece 13, the power interface 12 can be hidden, and the power interface 12 and other parts in the installation space 113 are not easily seen from the appearance, which better ensures the integrity of the overall appearance structure of the battery box and improves the overall appearance of the appearance. And the shielding piece 13 can also provide a certain protection effect, which can block a part of the interference of the external environment and improve the reliability of the battery box 1. At the same time, by forming the gap 114 between the shielding piece 13 and the side wall 112 in which the installation space 113 is formed, the connection requirement of the battery box 1 and the load is met, so as to improve the appearance while not affecting the normal use. The battery box 1 provided by the embodiment of the utility model has good appearance, and when a plurality of battery boxes 1 need to be stacked for use, parts for connecting and fixing adjacent battery boxes 1 can be arranged in the installation space 113, the installation space 113 is fully utilized, the structure is compact, and the stacking connection between the battery boxes 1 is also facilitated.

[0037] In some embodiments, as Figure 2As shown, mounting spaces 113 are provided on both of the two opposite side walls 112, and each mounting space 113 is covered by a shielding member 13 respectively. For example, in some embodiments, the shape of the box body 11 can be set to a shape similar to the Chinese character "工" (worker), so that mounting spaces 113 are formed on the side walls 112 on the opposite sides of the box body 11 respectively, and the mounting spaces 113 on both sides are covered by arranging the shielding members 13 respectively. When designed in this way, the overall battery box 1 has a symmetrical structure and good aesthetics. Moreover, the mounting spaces 113 on both sides can better meet the requirements for designing the power interfaces 12. Compared with only setting one mounting space 113, more numbers and / or types of power interfaces 12 can be provided. Of course, it is also possible to choose to provide the power interfaces 12 only in the mounting space 113 on one side, and the design flexibility is relatively high.

[0038] In some embodiments, such as Figure 2 As shown, the battery box 1 further includes a handle 14 mounted on the box body 11. The handle 14 is located within the mounting space 113 and is spaced apart from the power interface 12. Specifically, the handle 14 can be grasped by a person when moving and carrying the battery box 1. For example, in the assembly process of the battery box 1, the battery box 1 can be moved to a designated position through the handle 14, and then the shielding member 13 is installed. The shielding member 13 can cover and hide the handle 14 located within the mounting space 113. In this way, when the battery box 1 does not need to be carried, the handle 14 will not be exposed, making the overall appearance more concise and beautiful. Regarding the number of the handles 14 provided, optionally, only one handle 14 can be provided. When there are multiple mounting spaces 113, such as Figure 2 As shown, multiple handles 14 can also be provided correspondingly. Regarding the specific form of the handle 14, optionally, it can be mounted on the side wall 112 forming the mounting space 113 and protrude outward relative to the side wall 112. In addition, in some embodiments, such as Figure 2 As shown, the handle 14 can be an inlaid handle formed by being recessed inward relative to the side wall 112. This inlaid handle does not need to occupy external space, has a more compact structure, and is more conducive to being covered by the shielding member 13.

[0039] In some embodiments, such as Figure 2 and Figure 3 As shown, the battery box 1 further includes a mounting member 15. The mounting member 15 has a first end 151 and a second end 152. The first end 151 is connected to the box body 11, and the second end 152 is connected to the shielding member 13. Among them, there is a bending portion 153 between the first end and the second end 152. It can be understood that the first end 151 and the second end 152 are connected through the bending portion 153 and are bent at a certain angle. For example, in some embodiments, such as Figure 3As shown, along the same bending direction, the bending angle a of the bending part 153 relative to the first end 151 can be set to 135°, and the bending angle β of the second end 152 relative to the bending part 153 is also set to 135°, so that the included angle between the first end 151 and the second end 152 is 90°, so that the first end 151 and the second end 152 can be connected at positions perpendicular to each other. Of course, the included angle between the first end 151 and the second end 152 can also be other degrees, which can be designed according to the structure of the box body 11 and the corresponding connecting mounting part 15 of the shielding part 13, as long as the mounting part 15 can be connected and adapted.

[0040] The above embodiment realizes the connection of the shielding part 13 and the box body 11 by setting the mounting part 15, and the mounting part 15 has high design flexibility and can better adapt to the connection of the shielding part 13 and the box body 11. The mounting part 15 can also be arranged in the mounting space 113, so as to be covered by the shielding part 13 when the shielding part 13 is connected, thereby improving the aesthetic appearance and fully utilizing the mounting space 113, and having good compactness.

[0041] In some embodiments, the mounting space 113 can be recessed in the direction of the containing cavity 111 of the side wall 112, that is, the mounting space 113 can be directly formed on the side wall 112 by integral molding or machining. When this setting method is adopted, the shielding part 13 can be directly connected to the side wall 112, or the mounting part 15 can be arranged on the side wall 112, and the shielding part 13 is connected to the mounting part 15, as long as the reliable connection of the shielding part 13 can be realized, and the shielding part 13 can cover the mounting space 113.

[0042] In other embodiments, as shown in Figure 2 The battery box 1 includes a partition 16 connected to the box body 11, and the partition 16 can be arranged at least two on the same side wall 112, and the mounting space 113 is formed between the adjacent two partitions 16, and the shielding part 13 is connected to the partition 16 to fix the installation position of the shielding part 13 and cover the mounting space 113.

[0043] Specifically, when the partition 16 is provided with only two on the same side wall 112, the shielding piece 13 can be provided with only one on the side wall 112 and connected with the two partitions 16 respectively. In some embodiments, the two partitions 16 can be provided at two ends of the same side wall 112 in the horizontal direction, so that a larger mounting space 113 can be formed between the two partitions 16 to accommodate more power interfaces 12 and connecting components such as the mounting piece 15. When the number of partitions 16 provided on the same side wall 112 is more than two, optionally, one shielding piece 13 can be connected with each partition 16, or only connected with part of the partitions 16, or a plurality of shielding pieces 13 can be provided, each of which is connected with two adjacent partitions 16, as long as each mounting space 113 can be covered by the shielding piece 13. For the connection mode of the shielding piece 13 and the partition 16, the shielding piece 13 can be connected with the partition 16 through the mounting piece 15, or the mounting piece 15 and the partition 16 can be integrally formed, and the shielding piece 13 is connected with the integrally formed component.

[0044] In some embodiments, when the battery box 1 is provided with a handle 14, the handle 14 can be connected with the partition 16, connected only on the side wall 112, or connected on the partition 16 and the side wall 112 at the same time. It can be understood that the arrangement of the mounting space 113 is not unique, and the design flexibility is high.

[0045] As shown in Figure 4 The utility model embodiment further provides a stacked power supply device 2, comprising a plurality of above -mentioned battery box 1, each battery box 1 is connected in turn layering. When stacking the battery box 1, as shown in Figure 5 The gap 114 formed by each battery box 1 is connected in correspondence with the height direction of the stacking of the battery box 1, that is, the gap 114 on the first battery box 1 is connected with the gap 114 on the second battery box 1, and the gap 114 on the second battery box 1 is connected with the gap 114 on the third battery box 1, and so on, so that the mounting spaces 113 on the same side between the adjacent two battery boxes 1 are connected with each other. In this way, the cable connected between the load and the power interface 12 can be connected through the gaps 114 in sequence, so that the cable can be concentrated in the same position, and the problem of messy wiring can be avoided, and the appearance can be improved.

[0046] The stacked power supply device 2 provided by the utility model embodiment adopts the above-mentioned battery box 1 layering connection, and the battery box 1 has good appearance by adopting the design of the mounting space 113, the shielding piece 13 and the like, so that the stacked power supply device 2 has simple structure, easy assembly and good appearance.

[0047] In some embodiments, as shown inFigure 4 and Figure 5 As shown in FIGS. 1 and 2, the stacked power supply device 2 further comprises a base 21, a first connecting member 22 and a second connecting member 23. Among them, the lowermost battery box 11 is connected to the base 21 through the first connecting member 22 along the height direction of the stacked battery boxes 1, and the adjacent two battery boxes 11 are connected through the second connecting member 23 respectively. The above embodiment can improve the stability of the structure by arranging the base 21 to bear each battery box 1, and the battery box 1 does not need to be placed directly on the surface, which can reduce the problem of wear and tear on the lowermost box 11. At the same time, by connecting the lowermost box 11 to the base 21 through the first connecting member 22 and connecting the adjacent two boxes 11 through the second connecting member 23, the structural strength is further increased, and the reliability of the stacked power supply device 2 is improved.

[0048] In some embodiments, as shown in FIGS. 1 and 2, Figure 5 and Figure 6 The first connecting member 22 has a first limiting portion 221, a first connecting portion 222 and a second connecting portion 223 arranged at an angle with each other. The first limiting portion 221 abuts against the corresponding box 11, the first connecting portion 222 is connected to the base 21, and the second connecting portion 223 is connected to the side wall 112. For example, the first limiting portion 221, the first connecting portion 222 and the second connecting portion 223 can be arranged perpendicular to each other, or can be arranged at other angles, as long as they can meet the connection requirements of the base 21 and the box 11. It can be understood that the first limiting portion 221, the first connecting portion 222 and the second connecting portion 223 are connected to each other.

[0049] In some embodiments, as shown in FIGS. 1 and 2, Figure 5 and Figure 7 The second connecting member 23 has a second limiting portion 231 and a third connecting portion 232 arranged at an angle with each other; the second limiting portion 231 abuts against the adjacent two boxes 11, and the third connecting portion 232 is connected to the adjacent two boxes 11. For example, the second limiting portion 231 and the third connecting portion 232 can be arranged perpendicular to each other, or can be arranged at other angles, as long as they can meet the connection requirements of the adjacent two boxes 11. It can be understood that the second limiting portion 231 and the third connecting portion 232 are connected to each other.

[0050] When the first connecting member 22 and the second connecting member 23 adopt the above design, in some embodiments, as shown in FIGS. 1 and 2, Figure 5As shown, each box body 11 can be set in a shape similar to the Chinese character "工", or a separator 16 can be connected to the box body 11 to form this shape, so that the installation space 113 is arranged through the box body 11 in the height direction, and both side edges of the installation space 113 in the horizontal direction form a certain angle with the side wall 112. In this way, during assembly, the first connecting member 22 can be installed in the lowermost installation space 113, and the second connecting member 23 can be installed between two adjacent installation spaces 113 in the height direction, so that the first connecting member 22 and the second connecting member 23 can be covered and hidden by the shielding member 13. The effect after assembly is as Figure 4 shown. It is not easy to see the first connecting member 22 and the second connecting member 23 from the outside, making the appearance of the stacked power supply device 2 relatively simple and beautiful.

[0051] Specifically, taking the solution of connecting the separator 16 to the box body 11 as an example, the angle between the side of the separator 16 facing the installation space 113 and the side wall 112 can be set at 90° or other angles. The first connecting member 22 can first be connected to the base 21 through the first connecting portion 222. Then, when installing the lowermost battery box 1, the first limiting portion 221 can be abutted against the separator 16 on one side of the installation space 113, and the second connecting portion 223 is connected to the side wall 112, so that the angle between the first limiting portion 221 and the second connecting portion 223 is located at the angle between the separator 16 and the side wall 112. In some embodiments, two first connecting members 22 can be arranged in the same installation space 113, so that the first limiting portions 221 of the two first connecting members 22 are respectively abutted against the separators 16 on both sides of the same installation space 113, and the second connecting portions 223 of the two first connecting members 22 are respectively connected to the side wall 112 within the same installation space 113. In this way, through the abutting and limiting effect of the first limiting portion 221 and the separator 16, the loosening of the box body 11 in the horizontal direction during installation can be better restricted, achieving the positioning effect, and facilitating the alignment of the second connecting portion 223 with the installation position on the side wall 112 and connecting it to the side wall 112 during assembly. Similarly, when stacking and installing multiple battery boxes 1, the second connecting member 23 abuts against the separators 16 on two adjacent box bodies 11 through the second limiting portion 231, and a similar positioning effect can also be achieved, thus facilitating the assembly operation of each battery box 1.

[0052] Through the design of the above embodiments, the first connecting member 22 and the second connecting member 23 can limit the left - right movement of the box body 11 in the horizontal direction during the assembly operation, and can achieve reliable connection in the height direction, so as to better achieve the neat stacking of each battery box 1, simplify the connection structure, reduce the difficulty of the assembly operation, and further improve the aesthetics and reliability of the stacked power supply device 2.

[0053] In some embodiments, such as Figure 4 andFigure 5 As shown, the stacked power supply device 2 further comprises a top cover 24 and a third connecting member 25. Among them, the uppermost box 11 is connected with the top cover 24 through the third connecting member 25 in the height direction. The design scheme of the third connecting member 25 can be designed with reference to the first connecting member 22 described above, and will not be repeated here. In some embodiments, a wiring port 241 can be formed on the top cover 24, the wiring port 241 is connected with the gap 114 formed by the uppermost battery box 1, so that the cable connected between the load and each power interface 12 can pass through, and the cable is concentrated at the wiring port 241, preventing the problem of scattered and messy cable.
