[0034] The following reference Figures 1 to 12 This application describes a power module according to some embodiments.

[0035] See Figures 1 to 10 As shown, an embodiment of this application provides a power module, including: a housing 1 and a square-shell battery 2, a mounting member 3, and an inverter assembly 4 disposed within the housing 1; wherein, the mounting member 3 is fixed to the housing 1, and a battery mounting groove 36 is formed on one side of the mounting member 3 along a first preset direction a, the square-shell battery 2 is disposed in the battery mounting groove 36, and the thickness direction of the square-shell battery 2 is the same as or forms an angle with the first preset direction a, and the inverter assembly 4 is fixed to the opposite side of the mounting member 3 so that the square-shell battery 2 and the inverter assembly 4 are spaced apart.

[0036] As can be seen from the structure described above, this application uses a single large-capacity square-shell battery 2 and is equipped with a mounting component 3. The square-shell battery 2 is integrated into the battery mounting slot 36 on one side of the mounting component 3, and the inverter assembly 4 is integrated on the other side of the mounting component 3. This results in higher integration, a more compact structure, and fewer structural components, reducing installation steps and material costs. Installation and maintenance are also more convenient. In addition, the square-shell battery 2 and the inverter assembly 4 are separated by the mounting component 3, which reduces the risk of fire in case of thermal runaway and improves safety and reliability.

[0037] It should be noted that the prismatic battery in this application can be a 280Ah or 314Ah high-capacity prismatic battery. Of course, it is not limited to these, and can also be other models and capacities of prismatic batteries, etc., depending on the actual needs.

[0038] In this embodiment, preferably, as follows: Figure 1 , Figures 5 to 8 , Figure 11 and Figure 12 As shown, the power module also includes a battery clamping member 5, which is connected to the mounting member 3. The battery clamping member 5 has a mounting cavity with a bottom opening, and the battery clamping member 5 is pressed onto the top of the square battery 2 along its height direction through the mounting cavity. As can be seen from the structure described above, the top of the square battery 2 is limited by the battery clamping member 5, and at the same time, the bottom of the square battery 2 is limited by the bottom wall of the battery mounting groove 36, so that the square battery 2 does not move in the height direction, that is, in the vertical direction. Moreover, the side of the square battery 2 is limited by the side wall of the battery mounting groove 36, thus realizing the all-round limitation of the square battery 2, making the square battery 2 more stable.

[0039] In this embodiment, preferably, as follows: Figure 1 As shown, the power module also includes a first flexible insulating member 6, and the space between the side wall of the square battery 2 and the side wall of the mounting cavity is filled with the first flexible insulating member 6. The first flexible insulating member 6 serves to protect the square battery 2 and provide insulation.

[0040] Furthermore, preferably, the first flexible insulating element 6 is foam. Of course, it is not limited to this and can be selected according to actual needs. In this embodiment, preferably, as follows: Figure 5 As shown, the battery clamping member 5 and the mounting member 3 are detachably connected by a first fastening member 19, such as a screw or bolt. As described above, the battery clamping component 5 and the mounting component 3 are connected in a detachable manner, facilitating installation and disassembly, especially for later disassembly and maintenance. However, this is not the only option; the battery clamping component 5 can also be connected to the mounting component 3 in a non-detachable manner, depending on the specific needs.

[0041] In this embodiment, preferably, as follows: Figures 5 to 8 As shown, the battery clamping member 5 is disposed on the side of the mounting member 3 where the battery mounting groove 36 is formed. That is, the battery clamping member 5 is disposed on the side of the square battery 2, which facilitates its assembly with the top of the square battery 2.

[0043] As can be seen from the structure described above, the first limiting side plate 52 and the two second limiting side plates 53 abut against one side along the length direction and both sides along the width direction of the square battery 2, respectively. The fourth side of the square battery 2 abuts against the first support plate 31 of the mounting member 3, and the limiting top plate 51 is pressed on the top of the square battery 2, thereby limiting the top of the square battery 2 in all directions.

[0044] Furthermore, preferably, the battery clamping component 5 also includes two second adapter plates 54, two third adapter plates 55, and a mating plate 56. Each second limiting side plate 53 is equipped with a second adapter plate 54, a third adapter plate 55, and a mating plate 56. The third adapter plate 55 is connected to the second limiting side plate 53 through the second adapter plate 54. The second adapter plate 54 is a U-shaped plate with its opening facing the square battery 2, and the third adapter plate 55 is an L-shaped plate with its opening facing away from the square battery 2. The second adapter plate 54 is used for mounting... Figure 4 The third fastening member 23 on the right side of the upper middle part, the third adapter plate 55 and the first support plate 31 of the mounting plate are attached together and connected by the first fastening member 19; the mating plate 56 is connected to the top of the second adapter plate 54, and the mating plate 56 is inclined towards the square battery 2 side, which is adapted to the inclined area near the top of the side wall of the outer casing 1 and abuts against each other to improve the stability of the mating.

[0045] Furthermore, preferably, the battery clamping component 5 is a sheet metal part, and can be formed by bending and welding sheet metal, eliminating the need for separate mold manufacturing, thus reducing design and manufacturing costs. Of course, this is not the only advantage.

[0046] In this embodiment, preferably, as follows: Figure 1 As shown, the power module also includes a second flexible insulating member 7, and the space between the side wall of the square battery 2 and the side wall of the battery mounting groove 36 is filled with the second flexible insulating member 7. The second flexible insulating member 7 serves to protect the square battery 2 and provide insulation. Furthermore, preferably, the second flexible insulating element 7 is foam. Of course, it is not limited to this and can be selected according to actual needs. In this embodiment, preferably, as follows: Figure 1As shown, the power module also includes a first insulating layer 8, and the bottom wall of the square battery 2 and the two small sides of the square battery 2 arranged along its thickness direction are covered with the first insulating layer 8. The first insulating layer 8 plays the role of insulation and protection.

[0047] Furthermore, preferably, the first insulating layer 8 can be adhered to the square battery 2, but of course, it is not limited to this. In this embodiment, preferably, as follows: Figure 1 and Figure 8 As shown, the power module also includes a second insulating layer 9, which is disposed between the inverter assembly 4 and the mounting member 3, and serves as an insulating and protective layer. In this embodiment, preferably, as follows: Figure 8 As shown, the second insulating layer 9 and the mounting component 3 are detachably connected via the second fastening component. As can be seen from the structure described above, the second insulating layer 9 and the mounting component 3 are connected in a detachable manner, which facilitates installation and disassembly, and is especially convenient for later maintenance. Of course, the connection method between the second insulating layer 9 and the mounting component 3 is not limited to this; they can also be connected in a non-detachable manner. It should be noted that the second insulating layer 9 has corresponding holes, which can be fitted onto the press-fit nut post 38. The mounting component 3, the second insulating layer 9, and the inverter assembly 4 are fixed together by the sixth fastening component described later. At this time, the second fastening component and the sixth fastening component are the same structural component. Of course, it is not limited to this. The two can also be independent structural components. The connection positions of the mounting component 3 and the second insulating layer 9 and the connection positions of the mounting component 3 and the inverter assembly 4 are different, which means that fastening components at different positions are required for locking.

[0048] In this embodiment, preferably, as follows: Figure 8 As shown, the second insulating layer 9 is connected to the mounting component 3 by adhesive. As can be seen from the structure described above, in order to further reinforce the second insulation layer 9, it can also be bonded to the mounting component 3. Of course, it is not limited to this. The second insulation layer 9 can also be connected to the mounting component 3 by means of the aforementioned second fastening component or adhesive, depending on the actual needs. In this embodiment, preferably, as follows: Figure 5 and Figure 6 As shown, the power module also includes a cooling fan 10, which is disposed on the mounting member 3 and is disposed corresponding to the heat dissipation fins 43 of the inverter assembly 4. As can be seen from the structure described above, the cooling fan 10 is integrated on the mounting component 3, which can then dissipate heat for the inverter component 4 and the square battery 2, and the integration is higher and the structure is more compact. In this embodiment, preferably, as follows: Figures 5 to 8 As shown, the length direction of the mounting component 3 is the same as the length direction of the square battery 2, and along the length direction of the mounting component 3, cooling fans 10 are provided on opposite sides of the mounting component 3, and the airflow direction of the two cooling fans 10 is the same. As described above, the two cooling fans 10 form a straight airflow channel, resulting in better heat dissipation and ensuring operation at a reasonable temperature. Of course, the number of cooling fans 10 is not limited to two; it can be one or more, depending on actual needs.

[0049] In this embodiment, preferably, as follows: Figure 9 and Figure 10 As shown, the mounting component 3 includes a first support plate 31, a second support plate 32, a limiting plate 33, and a mounting plate. The second support plate 32 is disposed on one side of the bottom of the first support plate 31, and the two are perpendicularly connected. It can be seen that the second support plate 32 is parallel to the horizontal direction, and the first support plate 31 is parallel to the vertical direction. The thickness direction of the first support plate 31 is the same as the thickness direction of the square battery 2. There are multiple limiting plates 33, which are arranged along the circumference of the second support plate 32 and together with the second support plate 32 and the first support plate 31, they form a battery mounting groove 36. The inverter assembly 4 is mounted on the side of the second support plate 32 away from the first support plate 31. Along the length direction of the second support plate 32, mounting plates are provided on opposite sides of the second support plate 32 along its length direction, and a cooling fan 10 is mounted on each mounting plate. As can be seen from the structure described above, the lower part of the second support plate 32 and the first support plate 31 serves as the bottom wall of the battery mounting groove 36, and the multiple limiting plates 33 serve as the side walls of the battery mounting groove 36; the side of the first support plate 31 facing away from the square battery 2 provides an installation position for the inverter assembly 4 and also serves to support the inverter assembly 4; the first support plate 31 is spaced between the square battery 2 and the inverter assembly 4, which serves as a spacer and reduces the risk of fire in case of thermal runaway; there can be multiple mounting plates, some of which can be used to install the cooling fan 10, and some of which can be used to install structural components such as the fourth fastening component described below.

[0050] Furthermore, preferably, the mounting component 3 further includes a first adapter plate 37, which is disposed perpendicular to the limiting plate 33 and extends in a direction away from the second support plate 32. The first adapter plate 37 is attached to the base 101 and connected to the base 101. Furthermore, preferably, the first adapter plate 37 and the base 101 can be detachably connected by screws or bolts.

[0051] Furthermore, preferably, the mounting component 3 is a sheet metal part, and can be formed by bending and welding sheet metal, eliminating the need for separate mold manufacturing, thus reducing design and manufacturing costs. Of course, this is not the only advantage.

[0053] Furthermore, preferably, the mounting plate used to install the third fastening member 23 can be a second mounting plate 35, and the second mounting plate 35 is arranged along the first preset direction a, that is, perpendicular to the first support plate 31. Of course, it is not limited to this, and can be designed according to actual needs.

[0054] Furthermore, preferably, the inverter assembly 4 includes a circuit board 41, a plurality of electrical components 42 and the aforementioned heat dissipation fins 43. The circuit board 41 is fixed on the side of the first support plate 31 of the mounting member 3 away from the second support plate 32, and the plurality of electrical components 42 are fixed on the side of the circuit board 41 away from the first support plate 31. The inverter assembly 4 is prior art and will not be described in detail here.

[0055] In this embodiment, preferably, as follows: Figure 1 and Figure 7 As shown, the power module also includes a positive lead-out bar 11, a negative lead-out bar 12, a positive connection bar 13, and a negative connection bar 14. The positive lead-out bar 11 and the negative lead-out bar 12 are respectively disposed on the top of the square-shell battery 2 and connected to the positive and negative terminals of the corresponding square-shell battery 2. One end of the positive connection bar 13 is connected to the inverter assembly 4, and the other end of the positive connection bar 13 is detachably connected to the positive lead-out bar 11 via two first auxiliary fastening components 21, such as screws or bolts. One end of the negative connection bar 14 is connected to the inverter assembly 4, and the other end of the negative connection bar 14 is detachably connected to the negative lead-out bar 12 via two second auxiliary fastening components 22, such as screws or bolts. As can be seen from the structure described above, the circuit board 41 of the inverter assembly 4 is electrically connected to the positive terminal of the prismatic battery 2 using the positive connection bar 13 and the positive lead bar 11, and the circuit board 41 of the inverter assembly 4 is electrically connected to the negative terminal of the prismatic battery 2 using the negative connection bar 14 and the negative lead bar 12. Moreover, the positive connection bar 13 and the positive lead bar 11 are detachably connected by two first auxiliary fastening members 21, and the negative connection bar 14 and the negative lead bar 12 are detachably connected by two second auxiliary fastening members 22. This can effectively prevent the connection bar from rotating when the aforementioned auxiliary fastening members are locked. Furthermore, the above is a detachable connection method, which is particularly convenient for later maintenance.

[0056] Furthermore, preferably, the positive connecting bar 13 and the negative lead-out bar 12 are fitted with insulating sleeves to provide insulation protection.

[0057] In this embodiment, preferably, as follows: Figure 1 and Figure 2 As shown, the outer casing 1 includes a base 101 and a main casing 102; wherein, the mounting member 3 is connected to the base 101; the main casing 102 has an internally hollow structure with an open bottom, and the main casing 102 covers the bottom of the mounting member 3 and the base 101, and the main casing 102, the base 101, and the mounting member 3 are detachably connected by a third fastening member 23, such as a screw or bolt, that is, the third fastening member 23 connecting the main casing 102 and the base 101 is... Figure 4 The third fastening member 23 in the lower middle part, the third fastening member 23 connecting the main housing 102 and the mounting member 3 is Figure 4 The third fastening member 23 on the right side of the upper middle part. As can be seen from the structure described above, the outer casing 1 is designed as two parts. This allows the assembly of structural components such as the square battery 2, mounting component 3, and inverter assembly 4 to be first installed together with the base 101. Then, the main casing 102 is placed over the outside of the above-mentioned assembly structure, and finally, the main casing 102 is locked to the base 101, improving the convenience of operation. Of course, the structure of the outer casing 1 is not limited to the above.
