[0049] The core of this application lies in providing a support module to improve the installation applicability of energy storage devices.

[0050] Another core of this application lies in providing an energy storage device with the above - mentioned support module.

[0051] The following further elaborates on this application in conjunction with the accompanying drawings and embodiments. It can be understood that the specific embodiments described herein are merely used to explain the relevant application and do not limit the application. The described embodiments are only a part of the embodiments of this application, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in this application without creative efforts fall within the scope of protection of this application.

[0052] As described in the background art, the installation applicability of energy storage devices in the prior art is poor. To improve the installation applicability of energy storage devices, this application provides a support module, which can realize the wall - mounting and floor - mounting of energy storage devices. In the examples of this application, taking the energy storage device including a battery module as an example for introduction, for the convenience of understanding, the general structure of the battery module is first introduced.

[0053] See Figure 1 , Figure 1 (a) is the top - view three - dimensional view of the battery module 100; Figure 1 (b) is the bottom - view three - dimensional view of the battery module 100; where Figure 1 (a) shows the state when the battery module 100 is in normal use.

[0054] The battery module 100 is generally in a cuboid structure, having opposite top surface 100a and bottom surface 100b. When in normal use, the top surface 100a is usually placed upward and the bottom surface 100b is usually placed downward.

[0055] Since there is a possibility of stacking the battery modules 100, that is, multiple battery modules 100 are arranged in sequence along the stacking direction, where the top surface 100a and the bottom surface 100b of the battery module 100 are arranged opposite to each other along the stacking direction. Considering the stability during the stacking process of the battery module 100, positioning grooves 110 and / or positioning holes 120 are usually provided on the bottom surface 100b of the battery module 100, and positioning ribs 130 and / or positioning protrusions 140 are usually provided on the top surface 100a of the battery module 100. The number of the positioning grooves 110, the positioning holes 120, the positioning ribs 130, and the positioning protrusions 140 can be any number. And for one battery module 100, the positions and sizes of the positioning grooves 110 and the positioning ribs 130 match each other, and the positions and sizes of the positioning holes 120 and the positioning protrusions 140 match each other. In this way, when two adjacent battery modules 100 are stacked, the positioning grooves 110 and / or the positioning holes 120 of the upper battery module 100 correspond to the positioning ribs 130 and / or the positioning protrusions 140 of the lower battery module 100.

[0056] Figure 1 (a) There are six positioning ribs 130, which extend along the length direction, with two arranged in the middle, and two are arranged side by side on each side of the two positioning ribs 130 in the middle; the number of the positioning protrusions 140 is four, and the four positioning protrusions 140 are arranged at the four corners of the bottom surface 100b.

[0057] Figure 1 (b) There are six positioning grooves 110, which extend along the length direction, with two arranged in the middle, and two are arranged side by side on each side of the two positioning grooves 110 in the middle; the number of the positioning holes 120 is four, and the four positioning holes 120 are arranged at the four corners of the bottom surface 100b.

[0058] Of course, the above structure is only an example, and the above structure of the battery modules 100 with different specifications is different. For example, the number and arrangement spacing of the positioning grooves 110, etc.

[0059] The structure of the battery module 100 has been introduced above. The following specifically introduces the specific structure of the support module 200 with reference to the drawings:

[0060] See Figures 2 to 17 , the illustrated support module 200 includes a support portion 210, a wall hanging portion 220, and a supporting foot portion 230, where: the support portion 210 has a first end face 210a for supporting the battery module 100; the wall hanging portion 220 is arranged at the edge of the support portion 210, and the wall hanging portion 220 is provided with a plurality of mounting holes to be mounted on the wall surface 300 in cooperation with the fasteners 240; the supporting foot portion 230 is arranged on the second end face 210b for supporting the battery module 100 to support on the ground 400; the second end face 210b is arranged opposite to the first end face 210a.

[0061] It can be seen that in the support module 200 of the example of the present application, the wall-mounted part 220 can be installed on the wall surface 300 by the fastener 240, and the battery module 100 is supported by the support part 210 to realize the installation of the battery module 100 on the wall surface 300, as Figures 4 to 6 and Figure 14 shown; or it is supported on the ground 400 by the support feet 230, and the battery module 100 is supported by the support part 210 to realize the installation of the battery module 100 on the ground 400, as Figure 9 、 Figure 10 and Figure 17 shown. It can be seen that by adopting the support module 200 of the above example of the present application, at least the installation of the battery module 100 on the wall surface 300 and the ground 400 can be realized. In addition, the support module 200 can adapt to different ground surfaces 400, thereby improving the applicability during the installation of the battery module 100, that is, improving the applicability of the installation of the energy storage device.

[0062] It should be noted that the support part 210 is a plate-like structure or a frame structure. In the present application, the plate-like structure is mainly taken as an example for description. The support part 210 has opposite first end faces 210a and second end faces 210b. Among them, the first end face 210a is the face for carrying the battery module 100, and the second end face 210b is the face for carrying the support part 210.

[0063] In order to quickly observe the levelness of the support part 210 installed on the wall surface 300 or the ground 400, a spirit level 211 is further provided on the first end face 210a, as Figure 2 、 Figure 3 、 Figure 11 、 Figure 12 and Figure 15 shown. The spirit level 211 can be arranged at any position on the first end face 210a. In some examples, the spirit level 211 is arranged at the center position of the first end face 210a. In this way, not only the levelness in the length direction can be adjusted, but also the levelness in the width direction can be adjusted. Here, since the support part 210 is a plate-like structure, it itself has a length direction, a width direction, and a thickness direction, and the length direction, the width direction, and the thickness direction are perpendicular to each other in pairs. The length direction corresponds to the length of the support part 210, the width direction corresponds to the width of the support part 210, and the thickness direction corresponds to the thickness of the support part 210.

[0064] As described above about the battery module 100, positioning grooves 110 and / or positioning holes 120 are usually provided on the bottom surface 100b of the battery module 100 to improve the stability of the battery module 100 installed on the first end face 210a of the support part 210. The first end face 210a is provided with positioning ridges 212 that cooperate with the positioning grooves 110 for supporting the battery module 100, as Figures 6 to 8As shown. It should be noted that the number and positions of the above-mentioned positioning ribs 212 match the positioning grooves 110 on the battery module 100, wherein the number of the positioning ribs 212 is not more than the number of the positioning grooves 110 on the battery module 100.

[0065] Similarly, a plurality of positioning protrusions 213 are further provided on the first end face 210a, as Figures 6 to 8 shown. The number and positions of the positioning protrusions 213 match the positioning holes 120 on the battery module 100, wherein the number of the positioning protrusions 213 is not more than the number of the positioning holes 120 on the battery module 100.

[0066] The structure of the support part 210 has been described above in conjunction with the drawings. The structure of the support feet 230 will be described below in conjunction with the drawings. As described above, the function of the support feet 230 is to support the support part 210 to realize the installation of the battery module 100 on the ground 400. The support feet 230 and the support part 210 can be non-detachably connected or detachably connected. Of course, no matter which connection method is used, the support feet 230 can adjust the height of the support part 210 relative to the ground 400. In the figure, the support feet 230 are threadedly connected to the support part 210.

[0067] Specifically, the support feet 230 include support foot pads 231, threaded rods 232 and nuts 233. The support foot pads 231 are arranged at one end of the threaded rods 232. The other end of the threaded rods 232 is threadedly connected to the support part 210. The nuts 233 are threadedly connected to the threaded rods 232 to adjust the pre-tightening force between the threaded rods 232 and the support part 210, as Figure 3 and Figure 13 shown. One end of the threaded rod 232 is fastened to the locking hole 214 of the support part 210. By rotating the depth of the threaded rod 232 screwed into the locking hole 214, the length of the threaded rod 232 exposed from the support part 210 can be adjusted, so as to achieve the purpose of adjusting the length of the support feet 230. When the target length is reached, the nut 233 is tightened so that there is a certain pre-tightening force between the threaded rod 232 and the support part 210, preventing the threaded rod 232 from shaking relative to the support part 210 and improving the support stability of the entire support module 200.

[0068] The fastener 240 fixes the entire support module 200 on the wall surface 300 through the mounting holes. The mounting holes include at least two groups, and each group includes at least one waist-shaped hole. The relative position can be adjusted through the waist-shaped hole to achieve leveling. See Figure 2 and Figure 11, in the illustration, each group includes at least a first kidney-shaped hole 221 extending in a first direction and a second kidney-shaped hole 222 extending in a second direction, and the first direction and the second direction are perpendicular. The first direction may correspond to the thickness direction of the support portion 210, the second direction may correspond to the length direction of the support portion 210, or may be any direction between the thickness direction and the length direction, that is, the first kidney-shaped hole 221 and the second kidney-shaped hole 222 are arranged obliquely. By setting the mounting holes in this way, the leveling can be facilitated.

[0069] It should be noted that the wall-mounted portion 220 and the support portion 210 are relatively fixed in holes, as Figures 2 to 11 shown. At this time, the wall-mounted portion 220 and the support portion 210 may be an integral structure or a split structure. Among them, the integral structure can be understood as that the wall-mounted portion 220 and the support portion 210 are an integral casting or an integral forging; the split structure can be understood as being separate individuals and connected together by riveting, welding, or screw connection.

[0070] In order to improve the connection strength between the wall-mounted portion 220 and the support portion 210, multiple reinforcing ribs are provided in the transition region between the wall-mounted portion 220 and the support portion 210. Specifically, multiple first reinforcing ribs 223 are provided between the first side surface 220a of the wall-mounted portion 220 and the first end surface 210a of the support portion 210 to improve the connection strength here. Multiple second reinforcing ribs 224 are provided between the second side surface 220b of the wall-mounted portion 220 and the second end surface 210b of the support portion 210 to improve the connection strength here. Here, the wall-mounted portion 220 has a first side surface 220a and a second side surface 220b arranged oppositely, and the second side surface 220b can be used as an installation surface to avoid fitting. In order to ensure the levelness of the battery module 100 after being installed on the first end surface 210a, usually the installation surface is perpendicular to the first end surface 210a. [[ID=IO]]

[0071] Alternatively, the wall-mounted portion 220 and the support portion 210 can be rotatably connected and configured in a wall-mounted state and a foot state, as Figures 12 to 17 ; among them, Figures 12 to 14 shows a schematic diagram of the wall-mounted portion 220 and the support portion 210 in the wall-mounted state, Figures 13 to 17 shows a schematic diagram of the wall-mounted portion 220 and the support portion 210 in the foot state.

[0072] In some examples of the present application, the wall-mounted part 220 includes a rotating member 225, a mounting member 226, and a limiting member 227. The rotating member 225 is installed at the edge of the supporting part 210. The mounting member 226 is rotatably connected relative to the rotating member 225. The mounting hole is located in the mounting member 226. The limiting member 227 is fixed to the mounting member 226. An installation groove 215 for accommodating the rotation of the mounting member 226 is provided on the supporting part 210. When the wall-mounted part 220 is in the wall-mounted state, the mounting member 226 expands relative to the supporting part 210, and the limiting member 227 abuts against the supporting part 210, so that the first end face 210a of the supporting part 210 is perpendicular to the mounting surface of the mounting member 226. When the wall-mounted part 220 is in the foot state, the mounting member 226 folds relative to the supporting part 210, and the limiting member 227 disengages from abutting against the supporting part 210.

[0073] See 18, Figure 18 Schematically shows the position changes of the mounting member 226 and the limiting member 227 in the wall-mounted state and the foot state. Figure 18 (a) shows that in the wall-mounted state, the mounting surface of the mounting member 226 is generally perpendicular to the first end face 210a of the supporting part 210, and the limiting member 227 abuts against the second end face 210b of the supporting part 210 to limit the mounting member 226 from continuing to rotate in the direction of the arrow, so that the supporting part 210 can be stably in the above state.

[0074] Figure 18 (b) shows that in the foot state, the mounting member 226 abuts against the installation groove 215, and the mounting surface generally coincides with the first end face 210a, and the limiting member 227 is generally in a vertical state.

[0075] Under the action of the limiting member 227, the rotation range of the above-mentioned mounting member 226 is between 0° and 90°. The mounting member 226 can rotate between coinciding with the first end face 210a of the supporting part 210 (0°) and being perpendicular to the first end face 210a of the supporting part 210 (90°). Similarly, the rotation range of the limiting member 227 is between 0° and 90°. The limiting member 227 can rotate between coinciding with the second end face 210b of the supporting part 210 (0°) and being perpendicular to the second end face 210b of the supporting part 210 (90°).

[0076] The above introduces the supporting part 210, the wall-mounted part 220, and the foot part 230 in combination with the drawings. In order to improve the aesthetics or protection performance of the support module 200 in the examples of the present application, the support module 200 may further include a decorative edging 250, as Figure 11 shown. The decorative edging 250 extends along the thickness direction of the supporting part 210 and is slightly smaller than the height of the foot part 230. Without affecting the height adjustment of the foot part 230, it covers most of the foot part 230 as much as possible.

[0077] The present application also discloses an energy storage device, which includes a battery module 100 and the support module 200 described in any one of the above. The battery module 100 is stacked on the first end face 210a of the support module 200. Since the above support module 200 has the above beneficial effects, the energy storage device including the support module 200 has corresponding effects, which will not be elaborated here.
