[0062] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0063] The battery pack housing 1 according to an embodiment of the present invention is described below with reference to the accompanying drawings.

[0064] like Figures 1-4 As shown, the battery pack housing 1 according to this embodiment of the present invention has a receiving cavity for accommodating the battery module 50, and the housing 1 has a mounting part 12 and a hoisting part.

[0065] The mounting part 12 is used to install the power distribution component 40. At least part of the hoisting part is provided adjacent to or at least part of the mounting part 12. The hoisting part is adapted to be connected to the power device to hoist the battery pack 4. That is, by using the cooperation of the hoisting part and the power device, the battery pack 4 is hoisted onto the power device, thereby facilitating the power supply of the battery pack 4 to the power device.

[0066] The power distribution component 40 is responsible for the distribution of electrical energy in the battery pack 4, circuit protection, and system safety management, and has a certain weight. At least a portion of the hoisting part is placed near the mounting part 12 or at least a portion of the hoisting part is located on the mounting part 12, so that the electrical device of the hoisting part can share at least a portion of the force exerted by the power distribution component 40 on the mounting part 12, and thus share at least a portion of the force exerted by the power distribution component 40 on the housing 1.

[0067] Specifically, since the hoisting part is fixed on the electrical device, the force exerted by the power distribution component 40 on the mounting part 12 can be easily transmitted to the electrical device through the hoisting part. In this way, the force exerted by the electrical device on the hoisting part can be used to share part of the force exerted by the power distribution component 40 on the housing 1, thereby reducing the force exerted by the power distribution component 40 on the housing 1.

[0068] Therefore, according to the embodiment of the present utility model, the battery pack housing 1 is provided with a mounting part 12 for mounting the power distribution component 40, and the hoisting part is provided close to the mounting part 12 or at least part of the hoisting part is provided on the mounting part 12. This allows the hoisting part to use an electrical device to share at least part of the force exerted by the power distribution component 40 on the mounting part 12, thereby reducing the force exerted by the power distribution component 40 on the mounting part 12, and thus reducing the possibility of damage to the mounting part 12 and improving the stability of the power distribution component 40 mounted on the housing 1.

[0069] The following description, with reference to the accompanying drawings, describes the housing 1 of a battery pack according to a specific embodiment of the present invention.

[0070] In some specific embodiments of this utility model, such as Figures 1-4 As shown, the battery pack housing 1 has a receiving cavity for accommodating the battery module 50, and the housing 1 has a mounting part 12 and a hoisting part.

[0071] In some embodiments of this utility model, such as Figure 2 , Figure 3 As shown, the housing 1 includes a shell 11 and a first lifting member 20. The shell 11 defines a receiving cavity. The mounting part 12 is provided on the shell 11. The first lifting member 20 is provided with a lifting part so that the first lifting member 20 and the electrical device can be connected by the lifting part.

[0072] At least a portion of the first lifting member 20 is provided on the mounting portion 12. The first lifting member 20 is connected to the housing 11 so as to connect the housing 11 and the electrical device using the first lifting member 20, thereby fixing the battery pack 4 to the electrical device.

[0073] Specifically, since the first lifting component 20 is connected to the housing 11 and the electrical device respectively, when the power distribution component 40 is fixed on the mounting part 12, the weight of the power distribution component 40 can be transmitted to the first lifting component 20 through the mounting part 12, and then act on the housing 11 and the electrical device respectively. This allows the electrical device to share the force of the power distribution component 40 on the housing 11, thereby reducing the force of the power distribution component 40 on the housing 11, reducing the possibility of damage to the mounting part 12, and improving the stability of the power distribution component 40 installed on the housing 1.

[0074] In some optional embodiments of this utility model, such as Figure 3As shown, the first hoisting component 20 is provided with a first fixing hole 21, and the hoisting part includes a first fixing hole 22. The first fixing hole 21 is adapted to connect the first hoisting component 20 to the electrical device through the first fixing connector, so as to connect the first hoisting component 20 to the electrical device, thereby connecting the housing 1 to the electrical device and fixing the battery pack 4 to the electrical device.

[0075] In some embodiments, the first fixing member may be a screw or bolt, etc., without much limitation.

[0076] In some embodiments, the electrical device has a first connection hole, and a first fixing connector is adapted to pass through the first connection hole and extend into the first fixing hole 21, and to be threadedly engaged with the first fixing hole 21 to achieve a fixed connection between the electrical device and the first lifting member 20.

[0077] In some embodiments, a threaded sleeve is provided in the first fixing hole 21, and the threaded sleeve is welded to the hole wall of the first fixing hole 21. The electrical device is provided with a first connecting hole, and a first fixing connector is adapted to pass through the first connecting hole and threadedly engage with the first fixing hole 21 to fix the first lifting component 20 and the electrical device together.

[0078] In some specific embodiments of this utility model, such as Figure 4 As shown, the first lifting component 20 has a first protrusion 23 that protrudes in a direction away from the housing 11, and a first fixing hole 21 is provided in the first protrusion 23.

[0079] The first fixing hole 21 is provided on the first protrusion 23 to reduce the distance between the first fixing hole 21 and the first connection hole on the power device, so that the first fixing connector can pass through the first connection hole and connect to the first fixing hole 21. Then, the first hoisting member 20 is used to connect the box 1 and the power device together, and the battery pack 4 is fixed on the power device.

[0080] In addition, a first protrusion 23 is formed on the first lifting member 20 to improve the structural strength of the first lifting member 20 and thus improve the load-bearing capacity of the first lifting member 20, so as to use the first lifting member 20 to stably fix the battery pack 4 on the electrical device and to use the first lifting member 20 to stably fix the power distribution component 40 on the housing 11.

[0081] In some embodiments, such as Figure 1 , Figure 3 As shown, at least a portion of the first lifting component 20 is disposed on the mounting portion 12, and the first lifting component 20 is connected to the power distribution component 40.

[0082] Specifically, since the first lifting component 20 is connected to the housing 11 and the electrical device respectively, when the power distribution component 40 is fixed on the first lifting component 20, the weight of the power distribution component 40 can be transferred to the housing 11 and the electrical device respectively through the first lifting component 20. This allows the electrical device to share the force exerted by the power distribution component 40 on the housing 11, thereby reducing the force exerted by the power distribution component 40 on the housing 11, reducing the possibility of damage to the mounting part 12, and improving the stability of the power distribution component 40 installed on the housing 1.

[0083] In some examples, the first lifting member 20 has a second protrusion 27 that protrudes in a direction away from the housing 11. The second protrusion 27 is provided with a second fixing hole 22, which is adapted to connect the first lifting member 20 to the power distribution member 40 through a second fixing connector, so as to fix the power distribution member 40 to the housing 1.

[0084] The first hoisting component 20 and the power distribution component 40 are connected together by the second fixed connector, and the power distribution component 40 is fixed at the mounting part 12 of the housing 11, so that the weight of the power distribution component 40 can be applied to the housing 11 and the electrical device respectively through the first hoisting component 20.

[0085] In some embodiments, the second fixing member may be a screw or bolt, etc., without much limitation.

[0086] In some examples, the power distribution component 40 is provided with a second connection hole 431, and the second fixed connector is adapted to pass through the second connection hole 431 and extend into the second fixed hole 22, and is threadedly engaged with the second fixed hole 22 to realize the fixed connection between the power distribution component 40 and the first hoisting component 20.

[0087] In some embodiments, a threaded sleeve is provided in the second fixing hole 22, and the threaded sleeve is welded and fixed to the hole wall of the second fixing hole 22. The power distribution component 40 is provided with a second connecting hole 431, and the second fixing connector is adapted to pass through the second connecting hole 431 and threadedly engage with the second fixing hole 22 to fix the first lifting component 20 and the power distribution component 40 together.

[0088] In addition, the second fixing hole 22 is provided on the second protrusion 27 to reduce the distance between the second fixing hole 22 and the second connecting hole 431 on the power distribution component 40, so that the second fixing connector can pass through the second connecting hole 431 and connect to the second fixing hole 22, and then the power distribution component 40 can be fixed on the mounting part 12 of the housing 11 by the first lifting component 20.

[0089] In some embodiments, such as Figure 4As shown, the first lifting component 20 also includes a first mating plate 24. The first mating plate 24 extends around the outer edge of the first protrusion 23 and the second protrusion 27. The first mating plate 24 is welded and fixed to the housing 11 to stably fix the first lifting component 20 on the housing 11. The first lifting component 20 is used to connect the housing 11 and the electrical device, and the first lifting component 20 is used to connect the power distribution component 40 and the housing 11.

[0090] In some examples, such as Figure 4 As shown, the first mating plate 24 is provided with a first reinforcing protrusion 241, which facilitates the improvement of the strength of the first mating plate 24 and thus the load-bearing capacity of the first mating plate 24, so as to improve the stability of the fixed connection between the first lifting component 20 and the housing 11 when the first mating plate 24 and the housing 11 are welded and fixed together.

[0091] Furthermore, one end of the first reinforcing protrusion 241 is connected to the first protrusion 23, and the other end extends toward the edge of the first mating plate 24, so as to make full use of the space on the first mating plate 24 and increase the overall strength of the first mating plate 24.

[0092] In some examples, such as Figure 4 As shown, the first mating plate 24 is provided with a first notch 242 so that the material can undergo uniform deformation when the first lifting part 20 is stamped and deformed, so as to avoid stress concentration and tearing of the material, and thus improve the molding yield.

[0093] Specifically, a first protrusion 23 can be formed on the first lifting component 20 by stamping, and a first reinforcing protrusion 241 can be formed on the first mating plate 24 by stamping. Therefore, a first notch 242 is provided on the first mating plate 24 to adapt to the process that requires stamping of the first lifting component 20, reduce the forming difficulty, and facilitate the improvement of forming yield.

[0094] In some optional embodiments of this utility model, such as Figure 3 As shown, the first lifting component 20 is provided with a first positioning hole 251. The first positioning hole 251 is adapted to be positioned and engaged with the electrical device so that when the electrical device and the first lifting component 20 are fixed together, the relative positions of the first lifting component 20 and the electrical device can be positioned by the positioning engagement of the first positioning hole 251 and the electrical device, thereby smoothly connecting the first lifting component 20 and the electrical device together.

[0095] In some embodiments, the electrical device is provided with a first positioning protrusion, which is inserted into and cooperates with a first positioning hole 251 to position the electrical device and the first lifting component 20 by utilizing the cooperation between the first positioning protrusion and the first positioning hole 251.

At least one first positioning hole 251 is provided near one of the first fixing holes 21 so that the positioning hole 251 and the electrical device are positioned together so that the first fixing hole 21 corresponds to the first connecting hole, thereby enabling the first fixing connector to pass smoothly through the first connecting hole and be threaded into the first fixing hole 21, thus realizing the fixed connection between the first hoisting component 20 and the electrical device.

[0097] In some optional embodiments of this utility model, such as Figure 3 As shown, the first lifting component 20 is provided with a second positioning hole, and the power distribution component 40 is provided with a second positioning protrusion. The second positioning hole and the second positioning protrusion cooperate to position the relative positions of the first lifting component 20 and the power distribution component 40 when the power distribution component 40 and the first lifting component 20 are fixed together, thereby smoothly connecting the first lifting component 20 and the power distribution component 40 together.

[0098] In some embodiments, such as Figure 3 As shown, the first lifting component 20 is provided with a plurality of second fixing holes 22. The second fixing connector is adapted to pass through the second connecting hole 431 on the power distribution component 40 and be threadedly engaged with the second fixing hole 22.

[0099] In some optional embodiments of this utility model, such as Figure 1 , Figure 2 As shown, the first lifting member 20 extends around the mounting part 12 to be suitable for being arranged around the power distribution component 40, thereby facilitating the connection of the first lifting member 20 and the power distribution component 40 together. This allows the weight of the power distribution component 40 to be applied to the electrical device and the housing 11 through the first lifting member 20. The electrical device shares at least part of the weight of the power distribution component 40, thereby reducing the force exerted by the power distribution component 40 on the housing 11, reducing the possibility of damage to the mounting part 12, and improving the stability of the power distribution component 40 installed on the housing 1.

[0100] In some specific embodiments of this utility model, such as Figure 4 As shown, the first lifting component 20 includes a first fixed beam 261 and two second fixed beams 262. The first fixed beam 261 extends along a first direction, and the two second fixed beams 262 are arranged along the first direction, intersecting with the first fixed beam 261.

[0104] Specifically, the two second fixing beams 262 are located on the same side of the first fixing beam 261, so that the first fixing beam 261 and the two second fixing beams 262 are arranged around the outer edge of the power distribution component 40, thereby facilitating the connection between the power distribution component 40 and the first fixing beam 261 and the second fixing beams 262.

[0105] In some examples, such as Figure 3 , Figure 4 As shown, the first fixed beam 261 is provided with a first protrusion 23 and a second protrusion 27. The first protrusion 23 is provided with a first fixing hole 21, and the second protrusion 27 is provided with a second fixing hole 22.

[0106] The first fixed beam 261 has a portion in the second direction for connecting to the electrical device, and the other portion of the first fixed beam 261 in the second direction and the second fixed beam 262 are used for connecting to the power distribution component 40.

[0107] In some embodiments of this utility model, such as Figure 2 As shown, the edge of the mounting part 12 is provided with a third fixing hole 121. The third fixing hole 121 is arranged opposite to the first fixing hole 21 in the second direction. The third fixing hole 121 is adapted to connect the mounting part 12 and the power distribution component 40 through a third fixing connector, so as to firmly fix the power distribution component 40 to the housing 1.

[0108] The third fixing hole 121 is provided at the edge of the mounting part 12 so that the edge of the power distribution component 40 is fixedly connected to the edge of the mounting part 12 through the third fixing hole 121, thereby stably fixing the power distribution component 40 on the mounting part 12.

[0109] In addition, the third fixing hole 121 and the first fixing hole 21 are arranged opposite to each other in the second direction so that the third fixing hole 121 and the first fixing hole 21 are spaced apart, thereby avoiding interference between the connection of the power distribution component 40 and the housing 11 and the connection of the power device and the housing 11, so that the power distribution component 40 can be smoothly fixed on the housing 11 and the power device and the housing 11 can be smoothly connected together.

[0110] In some embodiments, the third fixing member may be a screw or bolt, etc., without much limitation.

[0111] In some examples, the power distribution component 40 is provided with a third connection hole 432, and a third fixed connector is adapted to extend through the third connection hole 432 into the third fixed hole 121 and to be threaded into the third fixed hole 121 to realize the connection between the power distribution component 40 and the mounting part 12.

[0112] In some embodiments, a threaded sleeve is provided in the third fixing hole 121, and the threaded sleeve is welded and fixed to the hole wall of the third fixing hole 121. The power distribution component 40 is provided with a third connecting hole 432, and the third fixing connector is adapted to pass through the third connecting hole 432 and threadedly engage with the third fixing hole 121 to fix the mounting part 12 and the power distribution component 40 together.

At least a portion of the second lifting components are located on the same side of the first lifting component 20 away from the mounting portion 12.

[0114] The first lifting component 20 has limited structural strength and area, making it impossible to fully fix the housing 1 and the electrical device. Therefore, a second lifting component is set in other areas of the housing 11 to connect the other areas of the housing 11 and the electrical device, thereby achieving stable fixation of the housing 1 and the electrical device, so as to stably fix the battery pack 4 on the electrical device.

[0115] In some optional embodiments of this utility model, each second lifting member has a third protrusion 33 that protrudes in a direction away from the housing 11. The third protrusion 33 is provided with a fourth fixing hole 31. The lifting member includes the fourth fixing hole 31. The fourth fixing hole 31 is adapted to connect the second lifting member to the electrical device through the fourth fixing connector, thereby connecting the housing 1 to the electrical device and fixing the battery pack 4 to the electrical device.

[0116] The third protrusion 33 is provided, and the fourth fixing hole 31 is provided on the third protrusion 33. This makes it easier to reduce the distance between the fourth fixing hole 31 and the fourth connecting hole on the power device, so that the fourth fixing connector can pass through the fourth connecting hole and connect to the fourth fixing hole 31. Then, the second lifting member is used to connect the housing 11 and the power device together, and the battery pack 4 is fixed on the power device.

[0117] In some embodiments, the fourth fixing member may be a screw or bolt, etc., without much limitation.

The electrical device is provided with a third positioning protrusion, which is inserted into and engaged with the third positioning hole 32.

[0123] When one of the third positioning protrusions is inserted into the elongated hole, the third positioning protrusion can move within the elongated hole, thereby adjusting the relative position of the electrical device and the second hoisting component, so that the other third positioning protrusions are inserted into the corresponding third positioning hole 32, and the fourth connecting hole corresponds to the fourth fixing hole 31.

[0124] In some embodiments, the electrical device is provided with a third positioning protrusion, which is engaged with a third positioning hole 32 to position the electrical device and the second lifting component by means of the engagement of the third positioning protrusion and the third positioning hole 32.

[0125] In some embodiments, such as Figure 3 As shown, the second hoisting component is provided with a plurality of fourth fixing holes 31. The fourth fixing connector is adapted to pass through the fourth connecting hole on the electrical device and be threaded into the fourth fixing hole 31. At least one third positioning hole 32 is provided close to one of the fourth fixing holes 31 so that the positioning cooperation between the third positioning hole 32 and the electrical device makes the fourth fixing hole 31 correspond to the fourth connecting hole, thereby enabling the fourth fixing connector to pass smoothly through the fourth connecting hole and be threaded into the fourth fixing hole 31, thus realizing the fixed connection between the second hoisting component and the electrical device.

[0126] In some embodiments of this utility model, such as Figure 5 , Figure 8 and Figure 11 As shown, the second lifting component also includes a second mating plate 34, which extends around the outer edge of the third protrusion 33. The second mating plate 34 is welded to the housing 11 to stably fix the second lifting component on the housing 11.

[0127] In some embodiments of this utility model, such as Figure 2 , Figure 5 As shown, the second lifting component includes a first lifting lug 301. The first lifting lug 301 is located on the side of the first lifting component 20 away from the mounting part 12 in the second direction. The first lifting lug 301 extends along the first direction. The third protrusion 33 of the first lifting lug 301 is provided with a plurality of fourth fixing holes 31 arranged at intervals along the first direction. The first direction, the second direction and the protrusion direction of the third protrusion 33 intersect each other.

[0128] The first lifting lug 301 has a second mating plate 34 that is welded to the housing 11 to achieve a fixed connection between the first lifting lug 301 and the housing 11. The first lifting lug 301 is fixedly connected to the electrical device through the fourth fixing hole 31 to achieve a fixed connection between the electrical device and the housing 1.

[0129] Specifically, the fourth fixed connector connects the first lifting lug 301 and the electrical device through the fourth fixing hole 31 on the first lifting lug 301, thereby increasing the fixing force between the electrical device and the housing 1 by utilizing the first lifting lug 301, and improving the stability of the connection between the electrical device and the housing 1.

[0130] In addition, multiple fourth fixing holes 31 are arranged along the first direction so that the electrical device and the first lifting lug 301 can be fixed by multiple fourth fixing connectors, thereby increasing the stability of the connection between the electrical device and the housing 1.

[0131] In some optional embodiments of this utility model, such as Figure 2 As shown, the second lifting component includes multiple first lifting lugs 301, which are arranged at intervals along a first direction and a second direction to connect the housing 1 and the electrical device, thereby increasing the stability of the connection between the electrical device and the housing 1.

[0132] In some embodiments, the third protrusion 33 of the first lifting lug 301 is provided with four fourth fixing holes 31 and two third positioning holes 32.

[0133] In some optional embodiments of this utility model, such as Figure 2 , Figure 8 As shown, the second lifting component includes a second lifting lug 302. The second lifting lug 302 is located on the side of the first lifting lug 301 away from the first lifting component 20 in the second direction. The second lifting lug 302 extends along the second direction. The third protrusion 33 of the second lifting lug 302 is provided with a plurality of fourth fixing holes 31 arranged at intervals along the second direction.

[0134] The second mounting plate 34 of the second lifting lug 302 is welded to the housing 11 to achieve a fixed connection between the second lifting lug 302 and the housing 11. The second lifting lug 302 is fixedly connected to the electrical device through the fourth fixing hole 31 to achieve a fixed connection between the electrical device and the housing 11.

[0135] Specifically, the fourth fixed connector connects the second lifting lug 302 and the electrical device through the fourth fixed hole 31 on the second lifting lug 302, thereby increasing the fixing force between the electrical device and the housing 1 by utilizing the second lifting lug 302, and improving the stability of the connection between the electrical device and the housing 1.

[0136] The multiple fourth fixing holes 31 are arranged along the second direction so that the electrical device and the second lifting lug 302 can be fixed by multiple fourth fixing connectors, thereby increasing the stability of the connection between the electrical device and the housing 1.

[0137] In some specific embodiments of this utility model, such as Figure 2 As shown, the first lifting member 20 is provided near the edge of the housing 11 on one side in the second direction, the first lifting lug 301 is provided at the middle position of the housing 11 in the second direction, and the second lifting lug 302 is provided near the edge of the housing 11 on the other side in the second direction, so that lifting parts are provided in different areas of the housing 11, and the lifting parts are used to fully connect the housing 11 and the power device, so as to stably fix the battery pack 4 on the power device.

[0138] In some specific embodiments of this utility model, such as Figure 2 As shown, the second lifting component includes multiple second lifting lugs 302, which are arranged at intervals along the first direction to connect the housing 11 and the electrical device, thereby increasing the stability of the connection between the electrical device and the housing 1.

[0139] In some examples, the third protrusion 33 of the second lifting lug 302 is provided with two fourth fixing holes 31 and two third positioning holes 32. The two fourth fixing holes 31 are located on both sides of the two third positioning holes 32, so that when the third positioning hole 32 is inserted and engaged with the third positioning protrusion on the power device, the multiple third positioning holes 32 on the second lifting lug 302 can correspond one-to-one with the fourth connecting holes on the power device, thereby enabling the fourth fixing connector to pass through the fourth connecting hole and threadedly engage with the third positioning hole 32 to fix the power device and the second lifting lug 302 together, thereby fixing the housing 1 and the power device together, and fixing the battery pack 4 to the power device.

[0140] In some specific embodiments of this utility model, such as Figure 8 As shown, the third protrusion 33 of the second lug 302 has a first plane 3021 and a second plane 3022 on the side facing away from the housing 11. The first plane 3021 and the second plane 3022 are offset in the protrusion direction of the third protrusion 33. The first plane 3021 and the second plane 3022 are respectively provided with a fourth fixing hole 31.

[0141] The first plane 3021 and the second plane 3022 are used to match the planes of the electrical device and the housing 11.

[0142] Specifically, after the wire harness on the electrical device is wrapped and bundled, it will protrude from the surface of the electrical device. Therefore, the first plane 3021 and the second plane 3022 are offset in the protrusion direction of the third protrusion 33 to avoid the wire harness, so that the second lug 302 can be smoothly connected to the electrical device.

[0143] In some specific embodiments of this utility model, such as Figure 2 , Figure 11As shown, the second lifting component includes multiple third lifting lugs 303. Some of the third lifting lugs 303 are located between the first lifting component 20 and the first lifting lug 301, while other third lifting lugs 303 are located between the first lifting lug 301 and the second lifting lug 302. The third protrusion 33 of the third lifting lug 303 is provided with a fourth fixing hole 31. In this way, the third lifting lug 303 can be used to supplement the weak area between the first lifting lug 301 and the first lifting component 20, and the weak area between the first lifting lug 301 and the second lifting lug 302, so that the fixing force between the housing 1 and the electrical device is more stable.

[0144] The third lifting lug 303 has a second mating plate 34 that is welded to the housing 11 to achieve a fixed connection between the third lifting lug 303 and the housing 11. The third lifting lug 303 is fixedly connected to the electrical device through the fourth fixing hole 31 to achieve a fixed connection between the electrical device and the housing 1.

[0145] Specifically, the third lifting lug 303 plays a structural reinforcement role because the local strength of the weak area between the first lifting lug 301 and the first lifting component 20 is insufficient, and the local strength of the weak area between the first lifting lug 301 and the second lifting lug 302 is insufficient. By fixing multiple third lifting lugs 303 to the whole vehicle, the strength of these weak areas can be improved.

[0146] In some examples, the fourth fixed connector connects the third lifting lug 303 and the electrical device through the fourth fixed hole 31 on the third lifting lug 303, thereby increasing the fixing force between the electrical device and the housing 1 by utilizing the third lifting lug 303, and improving the stability of the fixed connection between the electrical device and the housing 1.

[0147] In some embodiments, such as Figure 11 As shown, the third protrusion 33 of the third lifting lug 303 is provided with a fourth fixing hole 31 and two third positioning holes 32. The fourth fixing hole 31 is located between the two third positioning holes 32, so that when the third positioning hole 32 is inserted and engaged with the third positioning protrusion on the power device, the third positioning hole 32 on the third lifting lug 303 can correspond to the fourth connecting hole on the power device, thereby allowing the fourth fixing connector to pass through the fourth connecting hole and threadedly engage with the third positioning hole 32, fixing the power device and the third lifting lug 303 together, thereby fixing the housing 1 and the power device together, and fixing the battery pack 4 on the power device.

[0148] In some embodiments of this utility model, such as Figure 6 , Figure 9 and Figure 12As shown, the second mating plate 34 is provided with a second reinforcing protrusion 341, which facilitates the improvement of the strength of the second mating plate 34 and thus the improvement of the load-bearing capacity of the second mating plate 34, so as to improve the stability of the connection between the second lifting component and the housing 11 when the second mating plate 34 and the housing 11 are welded and fixed together.

[0149] In some embodiments of this utility model, such as Figure 8 As shown, the third protrusion 33 is provided with a reinforcing recess 342, which facilitates the improvement of the strength of the third protrusion 33. When the fourth fixed connector connects the second hoisting component and the electrical device through the fourth fixed hole 31 on the third protrusion 33, the possibility of deformation of the third protrusion 33 can be reduced, thereby improving the stability of the connection between the second hoisting component and the electrical device.

[0150] In some embodiments of this utility model, such as Figure 6 , Figure 12 As shown, the second mating plate 34 is provided with a second notch 343 so that the material can undergo uniform deformation when the second lifting part is stamped and deformed, so as to avoid stress concentration and tearing of the material, and thus improve the molding yield.

[0151] Specifically, a third protrusion 33 can be formed on the second lifting component by stamping, a second reinforcing protrusion 341 can be formed on the second mating plate 34 by stamping, and a reinforcing recess 342 can be formed on the second reinforcing protrusion 341 by stamping. Therefore, a second notch 343 is provided on the second mating plate 34 to adapt to the process that requires stamping the second lifting component, reduce the forming difficulty, and improve the forming yield.

[0152] In some embodiments, the second mating plate 34 of the first lifting lug 301 is provided with a plurality of spaced second notches 343, and the second mating plate 34 of the first lifting lug 301 is serrated.

[0153] In some embodiments, the second mating plate 34 of the third lug 303 is provided with a second notch 343, and the second mating plate 34 of the third lug 303 is in the shape of a butterfly wing.

[0158] According to the battery pack 4 of the present invention, by utilizing the housing 1 of the battery pack according to the above embodiment of the present invention, by providing a mounting part 12 for mounting the power distribution component 40 on the housing 1, and by setting the hoisting part close to the mounting part 12 or by setting at least part of the hoisting part on the mounting part 12, the power device of the hoisting part can share at least part of the force of the power distribution component 40 on the mounting part 12, thereby reducing the force of the power distribution component 40 on the mounting part 12, thereby reducing the possibility of damage to the mounting part 12 and improving the stability of the power distribution component 40 mounted on the housing 1.

[0159] In some embodiments of this utility model, the power distribution component 40 is arranged near the edge of the housing 1 in the second direction, which helps to reduce the space occupied by the power distribution component 40 on the housing 1, thereby improving the space utilization rate.

[0160] Furthermore, by positioning the power distribution component 40 near the edge of the enclosure 1 in the second direction, it is convenient to position the hoisting part in the central area of ​​the enclosure 1, thereby enabling a stable connection between the enclosure 1 and the electrical device using the hoisting part.

[0161] In some embodiments of this utility model, such as Figure 1 , Figure 15 As shown, the power distribution component 40 includes a mounting housing 400 and a power distribution body 41.
