[0056] The following reference Figures 1 to 19 This application describes electrical mounting components and battery packs according to some embodiments.

[0057] Example 1

[0058] See Figures 1 to 10 As shown, an embodiment of this application provides an electrical mounting assembly 10, including: a first mounting member 1, a second mounting member 2, a first electrical component 3, and a second electrical component 4; wherein, the second mounting member 2 is mounted on the first mounting member 1, and the second mounting member 2 and the first mounting member 1 are placed in different orientations; the first electrical component 3 is mounted on the first mounting member 1, and the second electrical component 4 is mounted on the second mounting member 2.

[0059] As can be seen from the structure described above, this application provides a novel electrical mounting assembly 10, which consists of two mounting plates with different orientations. Electrical components can be arranged on the two mounting plates according to actual conditions. For example, electrical components with smaller length and width but larger height can be arranged on the horizontally placed mounting plate, while electrical components with larger length and / or width but smaller height can be arranged on the vertically placed mounting plate. It can be seen that by rationally arranging electrical components on two mounting plates with different orientations, the space utilization rate is greatly improved.

[0060] Furthermore, preferably, the first mounting component 1 can be placed horizontally as a whole, and the second mounting component 2 can be placed vertically as a whole. It should be noted that the horizontal or vertical placement mentioned here refers to the overall placement of the first mounting component 1 and the second mounting component 2; their individual structures can be arranged in other directions according to actual needs. In addition, it should be noted that the first mounting component 1 and the second mounting component 2 can also be placed in other directions, specifically selected according to actual needs. For example, the first mounting component 1 can be placed in a direction inclined relative to the horizontal direction, and the second mounting component 2 can be placed in a direction inclined relative to the vertical direction, etc.

[0065] As can be seen from the structure described above, the first electrical component 3 and the first mounting component 1 are connected by threads, which makes installation and disassembly easier. Moreover, the structure is simple, stable, and has a long service life. In particular, for the assembly structure of the first electrical component 3 and the first mounting component 1 through the first stud 15 and the first threaded hole, the first stud 15 can also play a positioning role, improve the assembly accuracy, and make operation easier. It also avoids the problem that when bolts are used, the bolts need to penetrate both sides of the first mounting component 1, thereby affecting the installation of the first electrical component 3 on the other side.

[0066] It should be noted that, not limited to the above structure, all the first electrical components 3 on the first mounting component 1 can be connected to the first mounting component 1 through the assembly structure of the first stud 15 and the first threaded hole, or all the first electrical components 3 on the first mounting component 1 can be connected to the first mounting component 1 through the assembly structure of the first mounting hole 16, the second mounting hole and the first fastening component 6.

[0067] In addition, it should be noted that the first electrical component 3 and the first mounting component 1 are not limited to being connected by threads, but can also be connected by snap-fit ​​or welding, etc.

[0068] In this embodiment, preferably, as follows: Figure 1 and Figure 2 As shown, the electrical installation assembly 10 also includes a wire tie 5, which is mounted on the second installation member 2.

[0070] Furthermore, preferably, the wire tie 5 is disposed on the top of the second mounting member 2. Of course, it is not limited to this and can also be disposed in other positions.

[0071] Furthermore, preferably, there are multiple wire ties 5, which are arranged sequentially at intervals along the length of the second mounting member 2.

[0072] In this embodiment, preferably, as follows: Figure 6 and Figure 7 As shown, the second mounting member 2 is formed with a second stud 24, wherein at least a portion of the second electrical component 4 is formed with a second through hole, and the second stud 24 is detachably mounted in the second through hole and fixed by a second nut 25;

[0073] The second mounting member 2 has a third mounting hole, and at least a portion of the second electrical component 4 has a fourth mounting hole. The electrical mounting assembly 10 also includes a second fastening member, which is installed in the third and fourth mounting holes for detachably fixing the second electrical component 4 to the second mounting member 2.

[0074] As can be seen from the structure described above, the second electrical component 4 and the second mounting component 2 are connected by threads, which makes installation and disassembly easier. Moreover, the structure is simple, stable, and has a long service life. In particular, for the assembly structure of the second electrical component 4 and the second mounting component 2 through the second stud 24 and the second through hole, the second stud 24 can also play a positioning role, improve the assembly accuracy, and make operation easier. It also avoids the problem that when bolts are used, the bolts need to penetrate both sides of the second mounting component 2, thereby affecting the installation of the second electrical component 4 on the other side.

[0075] It should be noted that, not limited to the above structure, all the second electrical components 4 on the second mounting member 2 can be connected to the second mounting member 2 through the assembly structure of the second stud 24 and the second through hole, or all the second electrical components 4 on the second mounting member 2 can be connected to the second mounting member 2 through the assembly structure of the third mounting hole, the fourth mounting hole and the second fastening member.

[0076] In addition, it should be noted that the second electrical component 4 and the second mounting component 2 are not limited to being connected by threads, but can also be connected by snap-fit ​​or welding, etc.

[0077] In this embodiment, preferably, as follows: Figure 1 As shown, one of the multiple second electrical components 4 is an aerosol fire extinguishing component 41. Preferably, the aerosol fire extinguishing component 41 is disposed on the side of the second mounting component 2 near the battery module 30. Of course, it is not limited to this. The aerosol fire extinguishing component 41 can also be disposed on the opposite side of the second mounting component 2, depending on the actual needs.

[0078] As can be seen from the structure described above, when a fire breaks out inside the battery pack, the aerosol fire extinguishing component 41 plays a role in extinguishing the fire, thereby improving the safety and reliability of the battery pack. It should be noted that the aerosol fire extinguishing component 41 is a commonly used structure in the prior art, and will not be described in detail here.

[0079] Furthermore, preferably, the aerosol fire extinguishing component 41 is provided with an ear plate, the ear plate having the aforementioned second through hole and cooperating with the aforementioned second stud 24, and can be locked by the second nut 25. Of course, the connection structure is not limited to this, and can be selected according to actual needs.

[0080] Furthermore, preferably, the second electrical component 4 installed on the side of the second mounting member 2 away from the battery module 30 is a battery management system. Of course, it is not limited to this. Other types of electrical components may also be installed on the side of the second mounting member 2 away from the battery module 30. In addition, the battery management system and the aforementioned aerosol fire extinguishing component 41 may be interchanged.

[0081] Furthermore, preferably, the battery management system and the second mounting member 2 can be connected together via the aforementioned third mounting hole, fourth mounting hole, and second fastening member, etc. Of course, this is not the only possibility.

[0082] It should be noted that an aerosol fire extinguishing component 41 and / or a battery management system may also be installed on the first installation component 1, depending on actual needs.

[0083] In this embodiment, preferably, as follows: Figure 3 As shown, the first mounting component 1 includes a first plate 11, a second plate 12, a third plate 13 and a fourth plate 14 connected in sequence; wherein, the second plate 12 is arranged along a first preset direction;

[0084] Along the first preset direction, the first plate 11 and the third plate 13 are respectively disposed on opposite sides of the second plate 12 and are disposed perpendicular to the second plate 12, and the first plate 11 and the third plate 13 extend in opposite directions.

[0085] The fourth plate 14 is arranged perpendicularly to the third plate 13; the first plate 11 is used to abut and connect with the first target site, and the third plate 13 is used to abut and connect with the second target site.

[0086] As can be seen from the structure described above, the first plate 11 and the third plate 13 can be connected to the first target location, such as the side wall of the housing 40, and the second target location, such as the bottom wall of the housing 40, respectively, for example, by welding or bolting, thereby providing a firm support for the first mounting component 1 and making it more stable; the main plate 3021 provides an installation position for the second mounting component 2; the third plate 13 serves to connect the second plate 12 and the fourth plate 14, that is, to act as a transition.

[0089] In this embodiment, preferably, as follows: Figure 6 and Figure 7 As shown, the second mounting component 2 includes a second main board body 21 and an L-shaped support plate 22 and a bottom support plate 23 connected to the second main board body 21; wherein, the second main board body 21 is provided with L-shaped support plates 22 on both sides along its length direction, and the openings of the L-shaped support plates 22 are arranged opposite to each other; the bottom support plate 23 is provided on one side of the bottom of the second main board body 21.

[0090] As can be seen from the structure described above, the L-shaped support plates 22 on both sides and the bottom support plate 23 at the bottom both serve to support the second main body 21, making it more stable and firm. Moreover, the L-shaped support plates 22 on both sides and the bottom support plate 23 at the bottom can also abut against the first mounting component 1 and be connected by screws or bolts.

[0091] Furthermore, preferably, the second main board body 21, the L-shaped support plate 22 and the bottom support plate 23 are an integral structure, but of course, it is not limited to this.

[0092] In this embodiment, preferably, the second mounting member 2 and the first mounting member 1 are detachably connected by a third fastening member, such as a screw or bolt (not shown in the figure). This is a detachable connection method, which facilitates installation and disassembly, and is especially convenient for later disassembly, maintenance, or replacement. Of course, it is not limited to this; the second mounting member 2 and the first mounting member 1 can also be connected by welding or other methods.

[0093] Example 2

[0094] See Figures 11 to 19As shown, Embodiment 2 of this application also provides a battery pack, including a housing 40, a battery module 30, and the electrical mounting assembly 10 described in Embodiment 1 above, wherein the battery module 30 and the electrical mounting assembly 10 are both installed inside the housing 40. Therefore, it possesses all the beneficial technical effects of the electrical mounting assembly 10, and the same technical features and beneficial effects will not be repeated here.

[0095] In this embodiment, preferably, as follows: Figure 15 , Figure 17 and Figure 19 As shown, the outer wall of the housing 40 has a lifting part 50, and the lifting part 50 has a lifting hole 501. A lifting ring is hung in the lifting hole 501, and a lifting rope can also be installed in the lifting hole 501 to facilitate the lifting of the battery pack. In addition, this lifting hole 501 can also be used as a mounting hole for fixing the battery pack to the installation site.

[0096] The hoisting part 50 is a hollow shell structure formed by bending and assembling a flat plate 30211. While meeting the strength requirements, it also helps with lightweight design, saves material costs, and has a simple manufacturing process, which helps reduce costs. The hoisting part 50 has an avoidance notch 502 on the side near the box 40, which serves to avoid the second auxiliary fastening component described below.

[0097] In this embodiment, preferably, as follows: Figure 18 and Figure 19 As shown, the housing 40 includes an upper housing 401 and a lower housing 402. Both the upper housing 401 and the lower housing 402 have flanges 403. The flanges 403 of the upper housing 401 and the lower housing 402 are detachably connected by a second auxiliary fastening member. The battery pack also includes a sealing ring 60, which is compressed between the flanges 403 of the upper housing 401 and the lower housing 402.

[0098] As can be seen from the structure described above, the flange 403 of the upper box 401 and the flange 403 of the lower box 402 are joined together, which makes it easy to install bolts on the joined flange 403 to lock the two together. The compression sealing ring 60 between the flange 403 of the upper box 401 and the flange 403 of the lower box 402 plays a role in sealing and preventing water leakage.

[0099] In this embodiment, preferably, as follows: Figures 11 to 16As shown, the battery module 30 includes a cell assembly 301, a first auxiliary fastening member 70, and two end plates 302. Along the length of the cell assembly 301, the two end plates 302 are respectively disposed at both ends of the cell assembly 301. The end plate 302 includes a main body 3021 connected to it and a first mounting part 3022. The first mounting part 3022 is disposed on the side of the main body 3021 away from the cell assembly 301. A second mounting part 4021 is formed on the inner bottom wall of the housing 40. The first mounting part 3022 and the second mounting part 4021 are detachably connected by the first auxiliary fastening member 70.

[0100] As can be seen from the structure described above, this application provides a novel end plate structure for a battery module. A first mounting part 3022 is provided on one side of the main board body 3021, which cooperates with the second mounting part 4021 on the target, such as the housing 40 described below. This can effectively reduce the thickness of the main board body 3021. In other words, the main board body 3021 can be designed as a thin plate structure, which plays a role in cost reduction. This is of great significance in battery production. Moreover, there is no need to design weight reduction holes, which simplifies the processing technology and also reduces costs.
