The click out assembly provided by the application is described in detail below in connection with specific embodiments.

An embodiment of the present application provides a battery rack assembly, which includes a bracket 100, a first fixing member 300, and a second fixing member 400, as shown with reference to fig. 1 to 5. The battery rack assembly can be applied to energy storage equipment.

Wherein the bracket 100 is a basic member of the battery rack assembly of the present application, the bracket 100 may provide a mounting base for other at least partial components of the electromagnetic assembly of the present application, and the bracket 100 may also serve the purpose of protecting the other at least partial components of the battery rack assembly. The mounting region 111 is formed in the bracket 100, and components of the battery rack assembly may be disposed in the mounting region 111. The bracket 100 is further provided with a mounting/dismounting opening 112, and the mounting/dismounting opening 112 is communicated with the mounting area 111, so that other at least partial components of the battery rack assembly can be mounted in the mounting area 111 through the mounting/dismounting opening 112, or the components in the mounting area 111 can be taken out through the mounting/dismounting opening 112. The bracket 100 may be made of a metal material so that the bracket 100 has a better structural strength.

The battery part 200 is detachably disposed in the mounting area 111 of the bracket 100, specifically, the size and the shape of the mounting/dismounting opening 112 of the bracket 100 are matched with the shape and the size of the battery part 200, and the battery part 200 can be inserted into the mounting area 111 through the mounting/dismounting opening 112 or taken out through the mounting/dismounting opening 112. The first limiting groove 121 is disposed in the mounting area 111, the third limiting groove 221 is disposed on the battery portion 200, and the first fixing member 300 is detachably disposed in the first limiting groove 121 and the third limiting groove 221, so that the first fixing member 300 can be fixed in the first limiting groove 121 and the third limiting groove 221, and thus the first fixing member 300 is fixed with the bracket 100 and the battery portion 200, and the bracket 100 and the battery portion 200 are fixed relatively. When the first fixing member 300 is detached from the first limiting groove 121 and/or the third limiting groove 221, the first fixing member 300 can be separated from at least one of the bracket 100 and the battery portion 200, so that the bracket 100 and the battery portion 200 can be moved relatively, and the battery portion 200 can be detached from the mounting region 111.

Specifically, when the first fixing member 300 is detached from the first and third limiting grooves 121 and 221, the first fixing member 300 is separated from both the bracket 100 and the battery part 200, thereby allowing the bracket 100 and the battery part 200 to be separated. When the first fixing member 300 is detached from the first limiting groove 121 and not detached from the third limiting groove 221, the first fixing member 300 is separated from the bracket 100 and fixed to the battery part 200, so that the bracket 100 and the battery part 200 can be separated. When the first fixing member 300 is detached from the third limiting groove 221 and not detached from the first limiting groove 121, the first fixing member 300 is separated from the battery part 200 and fixed to the bracket 100, so that the bracket 100 is also separated from the battery part 200.

The bracket 100 is further provided with a second limiting groove 131, the second fixing member 400 is disposed on the battery portion 200, and the second limiting groove 131 is detachably disposed in the second limiting groove 131. When the second fixing member 400 is disposed in the second limiting groove 131, the second fixing member 400 may be fixed in the second limiting groove 131, so that the second fixing member 400 is fixed relative to the bracket 100, and the bracket 100 is fixed relative to the battery portion 200. When the second fixing member 400 is detached from the second limiting groove 131, the second fixing member 400 is separated from the bracket 100 and still connected to the battery part 200, so that the bracket 100 is also separated from the battery part 200. The first fixing piece 300 is assembled and disassembled with the first limiting groove 121 and the third limiting groove 221 in a clamping groove matched mode, the second fixing piece 400 is assembled and disassembled with the second limiting groove 131 in a clamping groove matched mode, so that the first fixing piece 300 is assembled and disassembled conveniently in the first limiting groove 121 and the third limiting groove 221, and the second fixing piece 400 is assembled and disassembled conveniently in the second limiting groove 131, and the battery part 200 and the bracket 100 are fixed and disassembled more conveniently and more efficiently.

The mounting/dismounting port 112 of the bracket 100 is oriented in the first direction, so that the battery part 200 can be mounted in the mounting area 111 or dismounted from the mounting area 111 by the reciprocating movement of the battery part 200 in the first direction. The first fixing member 300 is in a limit fit with the first limit groove 121 and the third limit groove 221 in a first direction and a second direction perpendicular to the first direction, and correspondingly, the bracket 100 and the battery part 200 are also in a limit fit in the first direction and the second direction. The second fixing member 400 is in limit fit with the second limit groove 131 in the third direction, and the third direction is perpendicular to both the first direction and the second direction. In summary, through the limit fit of the first fixing member 300 and the first limit groove 121 and the third limit groove 221, and the limit fit of the second fixing member 400 and the second limit groove 131, the bracket 100 and the battery portion 200 can be limited and fixed in the first direction, the second direction and the third direction, so that the battery portion 200 can be completely limited in the mounting area 111, and the connection between the battery portion 200 and the bracket 100 can be kept stable and reliable. Specifically, the first direction is shown as the X direction in fig. 1, the second direction is shown as the Y direction in fig. 1, and the third direction is shown as the Z direction in fig. 1.

In some embodiments, referring to fig. 7, 8 and 9, in order to make the first fixing member 300 limitably engaged with the first and third limiting grooves 121 and 221 in the first and second directions, the orientation of the groove opening of the first limiting groove 121 and the orientation of the groove opening of the third limiting groove 221 may be set to be the same as the third direction. When the direction of the slot opening of the first limiting slot 121 is the same as the third direction, the opposite inner walls in the first limiting slot 121 may be opposite in the first direction and the second direction, so when the first fixing member 300 is embedded in the first limiting slot 121, the outer wall of the first fixing member 300 abuts against the inner wall of the first limiting slot 121, so that the first fixing member 300 is in limiting fit with the first limiting slot 121 in the first direction and the second direction. When the slot opening of the third limiting slot 221 is oriented in the same direction as the third direction, the opposite inner walls of the third limiting slot 221 can be opposite in the first direction and the second direction, so that when the first fixing member 300 is embedded in the third limiting slot 221, the outer wall of the first fixing member 300 abuts against the inner wall of the third limiting slot 221, so that the first fixing member 300 is in limit fit with the third limiting slot 221 in the first direction and the second direction

Referring to fig. 10, the first fixing member 300 may specifically include a first fixing portion 310 and a second fixing portion 320, where the first fixing portion 310 and the second fixing portion 320 are connected, and the first fixing portion 310 may be embedded in the first limiting groove 121, and the second fixing portion 320 may be embedded in the third limiting groove 221. The first fixing member 300 may be an integral structure, specifically, the first fixing member 300 may bend the first fixing portion 310 and the second fixing portion 320 relatively through a sheet metal process, so that the first fixing member 300 has better structural strength. Foam can be further arranged on the outer walls of the first fixing portion 310 and the second fixing portion 320, when the first fixing portion 310 is embedded in the first limiting groove 121, the foam is located between the outer wall of the first fixing portion 310 and the inner wall of the first limiting groove 121, and is compressed, so that friction force between the first fixing portion 310 and the first limiting groove 121 can be increased, and the first fixing portion 310 is more stable when embedded in the first limiting groove 121. When the second fixing portion 320 is embedded in the third limiting groove 221, the foam is located between the outer wall of the second fixing portion 320 and the inner wall of the third limiting groove 221, and the foam is compressed, so that the friction between the second fixing portion 320 and the third limiting groove 221 can be increased, and the second fixing portion 320 is more stable when embedded in the third limiting groove 221.

In some embodiments, referring to fig. 3, in order to facilitate the user to mount and dismount the first fixing member 300 from the first and third limiting grooves 121 and 221, the first limiting groove 121 may be disposed adjacent to the mounting/dismounting port 112 of the bracket 100, and the third limiting groove 221 of the battery part 200 may be disposed adjacent to the mounting/dismounting port 112 when the battery part 200 is located in the mounting region 111 of the bracket 100. Thus, when the user needs to embed the first fixing member 300 in the first limiting groove 121 and the third limiting groove 221, the user does not have to go deep into the mounting region 111, so that the user can conveniently disassemble and assemble the first fixing member 300 from the first limiting groove 121 and the third limiting groove 221.

When the battery pack needs to be mounted in the mounting area 111 of the bracket 100, the battery pack can be pushed into the mounting area 111 from the mounting/dismounting opening 112, so that the battery part 200 is completely located in the mounting area 111 and the third limiting groove 221 of the battery part 200 is adjacent to the mounting/dismounting opening 112, and then the user can embed the first fixing member 300 in the first limiting groove 121 and the third limiting groove 221, so that the battery part 200 and the bracket 100 are relatively fixed in the first direction and the second direction.

In some embodiments, referring to fig. 1, 2, 3, 4 and 5, the bracket 100 of the present application may specifically include a frame 110 and a first limiting member 120, where the frame 110 is a main structure of the bracket 100, the mounting area 111 is located in the frame 110, and the mounting opening 112 is located on a surface of the frame 110. The frame 110 is a frame structure, so that the self weight of the bracket 100 is relatively light under the condition of better structural strength. The first limiting member 120 is disposed on the frame 110, and the first limiting groove 121 is disposed on the first limiting member 120. The first limiting member 120 is connected with the frame body 110, and specifically, the frame body 110 and the first limiting member 120 can be assembled after being processed separately, so that the difficulty of the preparation process of the bracket 100 is reduced. The frame 110 may specifically include a plurality of columns and beams, where the columns may stand on a horizontal plane and the beams may be connected between adjacent columns to form a frame structure. The first limiting member 120 may be specifically disposed on the upright at the mounting/dismounting opening 112, so that the first limiting groove 121 on the first limiting member 120 may be adjacent to the mounting/dismounting opening 112.

The battery part 200 may specifically include a battery body 210 and a second limiting member 220, the second limiting member 220 may be disposed on the battery body 210, the battery body 210 may specifically include an internal battery core and an external protective shell, the second limiting member 220 is disposed on an outer wall of the protective shell, and the third limiting groove 221 is disposed on the second limiting member 220, and the second limiting member 220 and the battery body 210 may be separately processed and then assembled, so as to reduce difficulty in a preparation process of the battery part 200.

Referring to fig. 8 and 9, the first limiting groove 121 is a through groove structure penetrating the first limiting member 120, and the third limiting groove 221 is a through groove structure penetrating the second limiting member 220. Therefore, the first limiting groove 121 and the third limiting groove 221 have two groove openings, and the first fixing member 300 can be embedded in the first limiting groove 121 and the third limiting groove 221 through any one of the openings of the first limiting groove 121 and the third limiting groove 221, so that the assembly and disassembly modes of the first fixing member 300 and the first limiting groove 121 and the third limiting groove 221 are further simplified.

The bracket 100 further includes a first boss 140, where the first boss 140 is disposed on the frame 110, and the first boss 140 is opposite to the notch of the first limiting groove 121, and when the first fixing portion 310 is embedded in the first limiting groove 121, at least part of the first boss 140 is further embedded in the first fixing portion 310. Therefore, the first boss 140 and the first fixing portion 310 can be fixed relatively, and the first boss 140 is fixedly connected with the frame 110, so that the first fixing portion 310 is connected with the bracket 100 more stably and reliably. Specifically, the first fixing portion 310 may be provided with a first positioning slot 311 that is matched with the first boss 140, and the first boss 140 may be embedded in the first positioning slot 311. The battery part 200 further includes a second boss 230, where the second boss 230 is disposed on the battery body, and the second boss 230 is opposite to the notch of the third limiting groove 221, and when the second fixing part 320 is embedded in the third limiting groove 221, at least part of the second boss 230 is further embedded in the second fixing part 320. Therefore, the second boss 230 and the second fixing portion 320 can be fixed relatively, and the second boss 230 is fixedly connected with the battery body 210, so that the connection between the second fixing portion 320 and the battery portion 200 is more stable and reliable. Specifically, the second fixing portion 320 may be provided with a second positioning groove 321 that is matched with the second boss 230, and the second boss 230 may be embedded in the second positioning groove 321.

In some embodiments, referring to fig. 2, 3 and 11, the stand 100 of the present application further includes a support member 130, wherein the support member 130 is connectable with the frame 110, the support member 130 is fixedly connected with the frame 110, and the support member 130 is located in the mounting area 111. The support 130 is provided with a support surface 132, and when the battery part 200 is located in the mounting region 111, the bottom of the battery part 200 is located on the support surface 132, so that the support surface 132 of the support 130 may constitute the bottom wall of the mounting region 111. The support 130 further has a first limiting surface 133, the first limiting surface 133 abuts against a side portion of the battery portion 200, and the side portion of the battery portion 200 has a certain gap with the first limiting surface 133, and the gap is smaller. When the battery part 200 is pushed into the mounting area 111 from the mounting/dismounting opening 112, the first limiting surface 133 may serve as a side wall of the mounting area 111 to pre-limit the battery part 200 in the horizontal direction, so as to prevent the battery part 200 from being deflected to a greater extent in the moving process along the first direction, and meanwhile, the first limiting surface 133 has a certain gap with the side portion of the battery part 200, and also prevent the first limiting surface 133 and the battery part 200 from generating friction resistance, so that the battery part 200 may be pushed into the mounting area 111 in the first direction more smoothly.
