DETAILED DESCRIPTION

[0069] The following describes in detail embodiments of the present application. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present application and are not to be construed as limiting the present application.

[0070] The present application discloses a connection structure.

[0071] The connection structure of an embodiment of the present application is described below with reference to FIG. 1 to FIG. 9 .

[0072] As shown in FIG. 1 to FIG. 3 , the energy storage device 100 includes an energy storage cabinet 110 and a mounting bracket 120 .

[0073] The energy storage cabinet 110 is used to store electricity for use by the user, like a large power bank. In addition, the energy storage cabinet 110 has various shapes, for example, the energy storage cabinet 110 can be a rectangular parallelepiped, a cube or a cylinder, etc., which is not limited in this application.

[0074] Mounting bracket 120 includes a first connecting portion 121 and a second connecting portion 122. First connecting portion 121 can be connected to energy storage cabinet 110. Second connecting portion 122 includes a connecting structure 130 that can be connected to a wall. This structure 130 allows energy storage device 100 to be connected to a wall, preventing it from tipping over and improving safety. The distance between connecting structure 130 and the back of energy storage cabinet 110 along the front-to-back direction is greater than L1, satisfying the requirement that L1 ≥ 10 mm.

[0075] There are many ways to connect the first connecting portion 121 to the energy storage cabinet 110. For example, in one embodiment, the first connecting portion 121 and the energy storage cabinet 110 can be screwed together by a screw connection. In another embodiment, the first connecting portion 121 and the energy storage cabinet 110 can be fixed together by welding. Specifically, this application does not limit this.

[0076] In addition, the connection structure 130 can be a through hole, specifically, the shape of the through hole can be a circular hole, or a long hole, etc. Of course, in other embodiments, the specific configuration of the connection structure 130 can be selected as needed, and this application does not limit this.

[0077] According to the energy storage device 100 provided in the embodiment of the present application, the distance between the connection structure 130 and the back of the energy storage cabinet 110 in the front-to-back direction is greater than L1, satisfying the requirement that L1 ≥ 10 mm. This ensures that when the energy storage cabinet 110 is mounted on a wall via the mounting bracket 120, a reasonable gap exists between the energy storage cabinet 110 and the wall. This reasonable gap facilitates heat dissipation from the back of the energy storage cabinet 110 and facilitates wiring layout, improving the user experience. It also prevents the energy storage device from tipping over, enhancing safety.

[0078] In one embodiment, the energy storage cabinet 110 may include a plurality of modules 111 stacked in sequence in an up-down direction. A first module 111a among the plurality of modules 111 may be provided with an avoidance groove 140 on a wall surface directly opposite to an adjacent second module 111b. The avoidance groove 140 may be open on the back of the first module 111a. The first connection portion 121 may extend from the avoidance groove 140 to be connected to the first module 111a or the second module 111b. Specifically, for example, the first connection portion 121 may extend from the avoidance groove 140 to be connected only to the first module 111a, or the first connection portion 121 may extend from the avoidance groove 140 to be connected only to the second module 111b. Such an arrangement can ensure a tight connection between the first module 111a and the second module 111b, thereby making the overall structure of the energy storage cabinet 110 stable, and the multiple modules 111 can fit tightly together without any gaps. It can also prevent the mounting bracket 120 from leaking out after the energy storage cabinet 110 is installed in place, thereby improving the aesthetics of the installation.

[0079] It should be noted that, in the above embodiment, two adjacent modules 111 can be connected and fixed by screws, or fixed by a snap-fit ​​structure, or fixed by welding, etc., and this application does not limit this.

[0080] In addition, the stacking of multiple modules reduces the depth dimension and occupies less space. The energy storage device is connected to the wall through the mounting bracket set on the back of the energy storage cabinet, which facilitates the heat dissipation of the energy storage cabinet and the arrangement of the wiring harness, avoids the leakage of the mounting bracket, and is beautiful and safe.

[0081] 3 , in one embodiment, a relief groove 140 may be provided on the bottom surface of the first module 111 a , and the second module 111 b may be located below the first module 111 a , so that the installer can operate simply when connecting the first connection portion 121 to the upper surface of the second module 111 b , thereby improving installation efficiency.

[0082] 1 , in one embodiment, the first module 111a may be a control box 111b and the second module may be a battery module 113 . This configuration can prevent the mounting bracket 120 from leaking and ensure that the battery module 113 has a high power storage capacity.

[0083] It should be noted that, in one embodiment, an inverter (box) and a terminal can also be provided on the control box 111b. In another embodiment, the control box 111b can also be provided at the top of the energy storage device 100. Specifically, this application does not limit this.

[0084] Of course, in other embodiments, the first module 111a can also be the upper one of the two adjacent battery modules 113, and the second module 111b can be the lower one of the two adjacent battery modules 113. In this way, the mounting bracket 120 can be prevented from leaking out and the aesthetics can be improved.

[0085] 1 , the energy storage device 100 may further include a base 160 , which may be connected to the bottom module 111 . This prevents the bottom module 111 from being damaged during stacking, thereby increasing the service life of the module 111 .

[0086] In addition, in the embodiment of the present application, the control box 112 can be located at the top. Of course, in other embodiments, the bottommost battery module 113 among the multiple battery modules 113 can be connected to the control box 112, and the control box 112 can be connected to the base 160. Specifically, the present application does not limit this.

[0087] 2 to 5 , in one embodiment, the second connection portion 122 may include a first connection plate 1221 , a second connection plate 1222 , and a partition plate 1223 .

[0088] The first connecting plate 1221 and the connecting structure 130 may be disposed on the first connecting plate 1221 .

[0089] It should be noted that the connection structure 130 can be disposed adjacent to the upper end of the first connection plate 1221, adjacent to the lower end of the first connection plate 1221, or in the middle of the connection plate. Of course, to ensure a secure connection between the first connection plate 1221 and the wall, multiple connection structures 130 can be provided, and the multiple connection structures 130 can be disposed adjacent to the upper end of the first connection plate 1221, adjacent to the lower end of the first connection plate 1221, and in the middle of the connection plate, respectively.

[0090] The second connecting plate 1222 may be opposite to and spaced apart from the first connecting plate 1221 , and the first connecting portion 121 may be mounted on the second connecting plate 1222 .

[0091] There are many ways to install the first connecting portion 121 on the second connecting plate 1222. For example, in one embodiment, the first connecting portion 121 can be welded and installed on the second connecting plate 1222. In other embodiments, the first connecting portion 121 and the second connecting plate 1222 can also be integrally formed, etc. This application does not limit this.

[0092] The partition 1223 can be sandwiched between the first connecting plate 1221 and the second connecting plate 1222, and the two ends of the partition 1223 can be connected to the first connecting plate 1221 and the second connecting plate 1222 respectively. By providing the partition 1223, a gap can be formed between the first connecting plate 1221 and the second connecting plate 1222, ensuring that the distance between the connecting structure 130 and the back of the energy storage cabinet 110 in the front-to-back direction is greater than L1, which is convenient for heat dissipation and circuit layout.

[0093] It should be noted that there are many ways in which the two ends of the partition 1223 can be connected to the first connecting plate 1221 and the second connecting plate 1222 respectively. For example, in one embodiment, the two ends of the partition 1223 can be welded and fixed to the first connecting plate 1221 and the second connecting plate 1222 respectively. In other embodiments, the two ends of the partition 1223 can also be integrally formed with the first connecting plate 1221 and the second connecting plate 1222 respectively. Specifically, this application does not limit this.

[0094] Referring to Figure 5, in one embodiment, the second connecting portion 122 may also include two first reinforcing plates 1224 clamped between the first connecting plate 1221 and the second connecting plate 1222. The two first reinforcing plates 1224 can be arranged opposite to each other and spaced apart in the left and right directions, and the two ends of each first reinforcing plate 1224 can be respectively connected to the first connecting plate 1221 and the second connecting plate 1222. In this way, the stability of the connection between the first connecting plate 1221 and the second connecting plate 1222 can be enhanced by setting the first reinforcing plates 1224, and the first connecting plate 1221 and the second connecting plate 1222 can be avoided from being deformed by force, so that the overall hardness and strength of the mounting bracket 120 are greatly improved.

[0095] 6 , in an embodiment of the present application, the mounting bracket 120 may include a box body 123 with an open upper end. A portion of a front plate of the box body 123 may be bent forward to form a first connecting portion 121, and a back plate of the box body 123 may form a second connecting portion 122. This arrangement ensures a reasonable gap between the energy storage cabinet 110 and the wall while saving costs and simplifying the structure. The mounting bracket 120 also has greater strength and hardness, making the overall structure of the mounting bracket 120 stable.

This arrangement has a simple structure and can provide a reasonable gap between the energy storage cabinet 110 and the wall to facilitate heat dissipation and wiring harness arrangement.

[0097] 9 , in one embodiment, a portion of the fourth connecting plate 1211 is bent away from the third connecting plate 1225 to form a bent abutting plate 1212 . The bent abutting plate 1212 is configured to abut against the side of the energy storage cabinet 110 . This configuration allows a gap to be created between the energy storage cabinet 110 and the wall, facilitating heat dissipation and wiring arrangement of the energy storage cabinet 110 , and resulting in a simple structure.

[0098] It should be noted that, in one embodiment, the left and / or right portions of the fourth connecting plate 1211 may be bent away from the third connecting plate 1225 to form the bent abutting plate 1212.
