DETAILED DESCRIPTION

[0022] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0023] It should be noted that all directional indications (such as up, down, left, right, front, back...) in the embodiments of the present invention are only used to explain the relative position relationship, movement status, etc. between the various components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0024] like Figures 1 to 4 As shown, a wall-mounted battery pack includes:

[0025] A battery pack housing 100 is provided with at least one groove 110, and the groove 110 has an opening 111 communicating with the outside;

[0026] The mounting assembly includes a first connection structure 200 detachably disposed in the groove 110, the first connection structure 200 includes a fixing portion 210, the fixing portion 210 is provided with a first connection hole 230 detachably connected to the groove 110, and the fixing portion 210 is provided with a first fixing surface 214 parallel to the axial direction of the first connection hole 230, when the first connection structure 200 is installed in place, the first fixing surface 214 abuts against the inner wall of the groove 110. This design effectively expands the contact area between the first connection structure 200 and the battery pack housing 100, so that when the battery pack is in a suspended state, the first fixing surface 214 can bear most of the weight of the battery pack and transmit the pressure to the entire fixing portion 210, which not only disperses the load of the screw, but also enhances the stability of the connection. Furthermore, since the fixing portion 210 is embedded in the groove 110 and can abut against the inner wall of the groove 110, the friction between the battery pack shell 100 and the first connection structure 200 is increased, and the risk of loosening of the first connection structure 200 due to vibration is effectively reduced, thereby effectively improving the safety of the battery pack.

[0027] Specifically, if Figures 1 to 4 As shown, in this embodiment, the wall-mounted battery pack is mainly composed of a battery pack shell 100, a battery cell assembly built into the battery pack shell 100, and a mounting assembly detachably connected to the battery pack shell 100.

[0028] In this embodiment, the battery pack housing 100 is rectangular and hollow, and the cell assembly is detachably built into the battery pack housing 100. The back side of the battery pack housing 100 is provided with at least one strip-shaped groove 110, and the groove 110 has an opening 111 connected to the outside to accommodate the fixing portion 210 of the first connection structure 200. The provision of the groove 110 expands the contact area between the first connection structure 200 and the battery pack housing 100, so that the first connection structure 200 and the battery pack housing 100 can form multiple points of contact, avoiding the situation that the battery pack is only stressed by the screws when it is suspended, thereby effectively dispersing the load of the screws and improving the reliability of the connection.

[0029] In this embodiment, the groove 110 is recessed toward the inside of the battery pack housing 100, and the width of the groove 110 is greater than the width of the first connection structure 200, ensuring that the first connection structure 200 can be smoothly installed in the groove 110. Preferably, the groove 110 is provided with two groups, which are arranged symmetrically up and down. This design provides multiple limit points for fixing the battery pack, so that the user can choose the fixing point according to the needs, which not only effectively enhances the adaptability and safety of the battery pack in various application scenarios, but also optimizes the overall performance and user experience.

[0030] In this embodiment, a plurality of first limit strips 120 are provided on the inner wall of the groove 110 facing the ground. The first limit strips 120 are arranged along the inner wall of the groove 110 and extend toward the opening 111. When the first connection structure 200 is installed in place, the first fixing surface 214 abuts against the first limit strip 120. This design enables the first fixing surface 214 to achieve indirect abutment with the inner wall of the groove 110, thereby dispersing the screw load, and avoids excessive contact between the first fixing surface 214 and the inner wall of the groove 110, thereby causing scratches on the surfaces of the two. Compared with the direct abutment of the first fixing surface 214 with the inner wall of the groove 110, the service life of the first connection structure 200 is effectively improved, while the weight of the battery pack shell 100 is reduced.

[0031] In this embodiment, the fixing portion 210 further includes a second fixing surface 215 arranged perpendicularly to the first fixing surface 214, and the inner wall of the groove 110 is further provided with a plurality of second limiting strips 130 arranged perpendicularly to the first limiting strip 120. When the first connection structure 200 is installed in place, the second fixing surface 215 abuts against the second limiting strip 130. This design further improves the multi-dimensional stability of the first connection structure 200 in the groove 110, that is, the first connection structure 200 can be effectively supported and limited in multiple directions, further enhancing the stability of the connection between the first connection structure 200 and the battery pack housing 100; and the limiting in multiple directions can also effectively reduce the impact of external vibration on the first connection structure 200, thereby reducing the risk of loosening.

[0032] Preferably, in this embodiment, the second fixing surface 215 is arranged opposite to the opening 111, and the plurality of second limiting strips 130 are also arranged along the length direction of the inner wall of the groove 110 and extend in a direction perpendicular to the ground. This design enables the second fixing surface 215 to achieve indirect contact with the inner wall of the other side of the groove 110, while avoiding excessive contact between the second fixing surface 215 and the inner wall of the other side of the groove 110, which would cause scratches on the surface.

[0033] In this embodiment, the fixing portion 210 includes a first fixing edge 211 and a second fixing edge 212 which are perpendicular to each other, a first fixing surface 214 is provided on the side of the first fixing edge 211 facing the first limiting strip 120, a second fixing surface 215 is provided on the side of the second fixing edge 212 facing the second limiting strip 130, and a plurality of first connection holes 230 are provided, which are respectively provided on the second fixing edge 212 and penetrate the second fixing edge 212. This design ensures the strength of the overall structure of the fixing portion 210 on the one hand, and further improves the connection strength between the first connection structure 200 and the battery pack housing 100 through the design of multiple first connection holes 230 on the other hand.

[0034] In this embodiment, the fixing portion 210 further includes a third fixing edge 213, which is connected to the second fixing edge 212 and arranged opposite to the first fixing edge 211, and a transition arc 240 is provided at the connection between the third fixing edge 213 and the second fixing edge 212, and at the connection between the second fixing edge 212 and the first fixing edge 211. This design not only improves the strength of the first connection structure 200 by adding the third fixing edge 213 and providing the transition arc 240, but also distributes the external stress more evenly, avoids stress concentration, and thus improves the durability and reliability of the structure.

[0035] In this embodiment, a side of the groove 110 provided with the second limiting strip 130 is also provided with a plurality of first fixing holes 140, and the first fixing holes 140 correspond to the first connecting holes 230 one by one. When the first connecting structure 200 is installed in place, the first fixing holes 140 are coaxial with the first connecting holes 230. This design ensures that the first connecting structure 200 and the battery pack housing 100 can be detachably connected by screws, which effectively improves the convenience of disassembly and assembly of the first connecting structure 200 and the battery pack housing 100 and the stability of the connection.

[0036] To achieve the connection between the first connection structure 200 and other structures, in this embodiment, the first fixed edge 211 extends toward the opening 111 and extends out of the opening 111. The first connection structure 200 also includes a bent portion 220 disposed at the extended end of the first fixed edge 211, and the bent portion 220 is bent toward the ground. This design allows the first connection structure 200 to be conveniently mounted on other structures, ensuring the convenience of hanging the battery pack.

[0037] Preferably, in this embodiment, a transition arc 240 is provided at the connection between the bending portion 220 and the first fixed edge 211 . This design effectively avoids stress concentration and improves the durability and reliability of the first connection structure 200 .

[0038] In this embodiment, the bent portion 220 is provided with a plurality of notches along the length direction, and these notches are provided on the opposite side of the first connection hole 230 and correspond one-to-one with the first connection hole 230, and these notches are larger than the first connection hole 230. This design allows the user to drive screws into the first connection hole 230 and the first fixing hole 140 through the notches during the installation of the first connection structure 200, thereby effectively improving the convenience of installing the first connection structure 200.

[0039] In this embodiment, the mounting assembly further includes a second connection structure 300, which includes a first mounting edge 310, and the first mounting edge 310 is provided with a plurality of second connection holes 311 penetrating the first mounting edge 310, and a snap-fitting slot 312 snap-fitting with the bent portion 220, and the snap-fitting slot 312 is parallel to the ground. This design enables the battery pack to be directly detachably connected to a device with a snap-fitting slot through the first connection structure 200, and to be detachably connected to other devices through screws through the second connection structure 300, thereby providing a variety of installation methods for the battery pack and enhancing the versatility and adaptability of the wall-mounted battery pack.

[0040] In this embodiment, the second connection structure 300 is in the shape of a U-shaped plate, and further includes a second installation edge 320 vertically arranged on both sides of the first installation edge 310, and a third connection hole 321 is arranged on the second installation edge 320, and second fixing holes 150 corresponding to the third connection holes 321 are also arranged on both sides of the battery pack housing 100. This design allows the first connection structure 200 to be clamped on the second connection structure 300, and screws can be driven into the third connection holes 321 and the second fixing holes 150 to achieve the connection between the second connection structure 300 and the battery pack housing 100. This further improves the connection strength between the battery pack and other devices, and at the same time reduces the impact of external vibration on the battery pack.
