Similarly, the second frame 202 can be disassembled from the first frame 200 and the supporting seat 201 respectively, so that the first frame 200, the second frame 202 and the supporting seat 201 of the wall-mounted bracket 20 can be disassembled, so that the wall-mounted bracket 20 is easy to store and pack, which can reduce transportation costs.

[0081] In addition, by adjusting the height of the second frame 202 , the distance between the first frame 200 and the supporting seat 201 can be adjusted, so that the wall-mounted bracket 20 is suitable for wall-mounting battery pack boxes 21 of different specifications.

[0082] Optionally, the second frame 202 is in a straight line shape and is connected between the bottom end of the first frame 200 and the top end of the supporting seat 201 .

[0083] Optionally, a fifth connection hole 2020 penetrating the first frame 200 is provided at one end of the second frame 202, and the fourth fastening member 293 passes through the fifth connection hole 2020 to detachably connect and fix the first frame 200 and the second frame 202. Optionally, a sixth connection hole 2021 penetrating the supporting seat 201 is provided at the other end of the second frame 202, and the fifth fastening member 294 passes through the sixth connection hole 2021 to detachably connect and fix the second frame 202 and the supporting seat 201.

[0084] In an optional solution of this embodiment, the supporting seat 201 includes a back plate 2012 , a positioning plate 2011 and a supporting plate 2010 .

[0085] The back panel 2012 is provided with a second connection portion 2013, which is detachably connected to the wall 1, so that the supporting seat 201 is detachable relative to the wall 1 through the second connection portion 2013. When the back panel 2012 is installed, it can be configured to fit the wall 1, so that the wall 1 can achieve stable support for the supporting seat 201 in the horizontal direction.

[0086] Optionally, the second connection portion 2013 is a second connection hole, so that the supporting seat 201 can be detachably connected to the wall 1 by a second fastening member 291 such as a bolt or a screw passing through the second connection hole.

[0087] Furthermore, the second connection part 2013 may be a long hole, so as to increase the allowable error of the installation of the back plate 2012 and the supporting seat 201 to which it belongs and the wall 1. Furthermore, there may be a plurality of second connection parts 2013.

[0088] The supporting plate 2010 is connected to the back plate 2012 and supports the first side plate 210 , that is, the supporting plate 2010 and the back plate 2012 are connected in an L shape. In the installed state, the supporting plate 2010 is located below the first side plate 210 and supports the first side plate 210 .

[0089] The positioning plate 2011 corresponds to the second side plate 211 connected between the back plate 2012 and the supporting plate 2010. It can be understood that the battery pack case 21 has two second side plates 211. Correspondingly, the supporting seat 201 includes two positioning plates 2011. The two positioning plates 2011 are respectively arranged corresponding to the two second side plates 211 of the battery pack case 21, and the two positioning plates 2011 are both connected between the supporting plate 2010 and the back plate 2012, so that the positioning plate 2011 plays a role in strengthening the connection structure between the supporting plate 2010 and the back plate 2012, and the two positioning plates 2011 are respectively used to limit the two second side plates 211 wrapped around the battery 250.

[0090] A second fastening structure is provided between the positioning plate 2011 and the second side plate 211, that is, each positioning plate 2011 is connected and fixed to its corresponding second side plate 211 through the second fastening mechanism, so that the battery pack case 21 is fastened and positioned relative to the supporting seat 201. In other words, after the battery pack case 21 is pushed into the supporting seat 201, the second fastening structure prevents the battery pack case 21 from shifting or even falling off relative to the supporting seat 201.

[0091] Optionally, the second fastening structure includes a seventh connection hole 2014 provided on the positioning plate 2011, an eighth connection hole 2110 provided on the second side plate 211, and a sixth fastening member 295.
