[0025] With the battery pack mounting bracket of this structural design, multiple bracket units 10 are connected by the first connecting portion 102 and the second connecting portion 103 to achieve stacking of multiple bracket units 10 along the first direction to form a compact stacked battery support structure. For each bracket unit 10, it has a battery pack accommodating space, and is provided with a battery pack disassembly and assembly port 101 arranged toward the second direction. Through the battery pack disassembly and assembly port 101, the battery pack 20 can be easily taken out from the corresponding battery pack accommodating space or placed into the battery pack accommodating space. When the battery pack is installed on the bracket for use, it is only necessary to stack and assemble multiple bracket units 10, and then push each battery pack 20 into the corresponding bracket unit 10 respectively. When some battery packs 20 need to be replaced or maintained, they can be easily pulled out through the battery pack disassembly and assembly port 101 without affecting other battery packs 20, which effectively improves the flexibility of battery pack arrangement and maintenance, and solves the technical problem of inconvenient management of a large number of battery packs in the related art.

[0026] In actual implementation, the specific forms of the first connection part 102 and the second connection part 103 can be flexibly selected, for example, bolt matching, rivet matching, clamping matching, etc. can be selected between the two, and the structural forms of the corresponding connection parts will also be different. The number of the first connection part 102 and the second connection part 103 can also be selected according to the convenience of installation, the firmness of stacking, etc.

[0027] Specifically, the bracket unit 10 includes a first frame 1, a second frame 2 and a connecting frame 3. The first frame 1 and the second frame 2 are arranged at intervals along the second direction. The connecting frame 3 connects the first frame 1 and the second frame 2. The battery pack disassembly and assembly port 101 is set on the first frame 1, and the battery pack accommodating space is the space between the first frame 1 and the second frame 2.

[0028] In this embodiment, the bracket unit 10 is composed of a first frame 1, a second frame 2 and a connecting frame 3 connecting the two together. After the first frame 1 and the second frame 2 are connected by the connecting frame 3, an overall frame of the bracket unit 10 is formed, thereby supporting and accommodating the battery pack 20 with a simple structure.

[0029] Specifically, the first frame body 1 and the second frame body 2 are annular structures, and the connecting frame 3 connects the bottom edge of the first frame body 1 with the bottom edge of the second frame body 2 .

[0030] In this embodiment, the structure of the first frame 1 and the second frame 2 is further simplified. The first frame 1 and the second frame 2 are designed to be annular structures, and the connecting frame 3 connects the bottom edges of the two annular frames. In this way, the battery pack 20 is supported and accommodated with a simpler structure, and the weight of the battery pack mounting bracket is reduced. The connecting frame 3 can also play an auxiliary supporting role, and can also play a certain supporting and guiding role for the installation or removal of the battery pack 20.

[0031] Specifically, a first limiting structure 11 is provided on the first frame 1. When the battery pack 20 is loaded into the battery pack accommodating space, the first limiting structure 11 cooperates with the battery pack 20 to limit the movement of the battery pack 20 relative to the bracket unit 10 along the second direction; and / or, a second limiting structure 21 is provided on the second frame 2. When the battery pack 20 is loaded into the battery pack accommodating space, the second limiting structure 21 cooperates with the battery pack 20 to limit the movement of the battery pack 20 relative to the bracket unit 10 along the second direction.

[0032] By designing a first limiting structure 11 on the first frame 1 and a second limiting structure 21 on the second frame 2, when the battery pack 20 is pushed into the battery pack accommodating space through the battery pack assembly and disassembly port 101, the first limiting structure 11 and the second limiting structure 21 can limit the battery pack 20.

[0036] In this embodiment, a first bending protrusion 12 is designed on the bottom edge of the first frame 1, and a second bending protrusion 22 is designed on the bottom edge of the second frame 2, so as to prop up the battery pack 20 to a certain height, which is beneficial to the heat dissipation of the battery pack 20. In addition, the two sides of the bending protrusion will form a relatively concave position, which is beneficial to facilitate wiring.

[0037] Specifically, a first support member 4 is provided at the bottom of the first bending protrusion 12, and the bottom surface of the first support member 4 is flush with the bottom surface of the first frame 1; and / or, a second support member 5 is provided at the bottom of the second bending protrusion 22, and the bottom surface of the second support member 5 is flush with the bottom surface of the second frame 2.

[0038] By disposing a first support member 4 at the bottom of the first bending protrusion 12 and a second support member 5 at the bottom of the second bending protrusion 22 , the structural strength of the first frame 1 and the second frame 2 can be effectively improved to ensure a stable support effect for the battery pack 20 .

[0039] Specifically, along the third direction, a first recessed portion 13 is provided on the bottom edge of the first frame 1 at positions on both sides of the first bending protrusion 12, a first supporting portion 14 is provided on the inner side of the first frame 1 at a position corresponding to the first recessed portion 13, and an upper surface of the first supporting portion 14 is flush with an upper surface of the first bending protrusion 12; and / or, along the third direction, a second recessed portion 23 is provided on the bottom edge of the second frame 2 at positions on both sides of the second bending protrusion 22, a second supporting portion 24 is provided on the inner side of the second frame 2 at a position corresponding to the second recessed portion 23, and an upper surface of the second supporting portion 24 is flush with an upper surface of the second bending protrusion 22; wherein the first direction and the second direction are both perpendicular to the third direction.

[0040] In this embodiment, the first support portion 14 and the second support portion 24 are designed in the recessed portions formed on both sides of the bending protrusion, which can further improve the structural strength of the first frame 1 and the second frame 2 and ensure a stable support effect for the battery pack 20.
