[0021] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the protection scope of this application.

[0022] With the continuous development of the machinery manufacturing industry, the application scope of robots is becoming increasingly wide. For example, quadruped robots are widely used in various fields such as inspection, testing, search and rescue, and transportation. They can replace humans in performing repetitive tasks and can work 24 hours a day without interruption.

[0023] For a quadruped robot, an internal battery pack 6 provides power to enable its movements. The battery pack 6 includes a battery housing 2, battery modules 3 inside the battery housing 2, and a circuit board 4 inside the battery housing 2. The circuit board 4 is typically located near the top of the battery housing 2. When multiple battery modules 3 are installed inside the battery housing 2, they are arranged side-by-side. This arrangement not only results in low structural strength of the battery pack 6 and inconvenient assembly, but also increases the height of the battery housing 2 to accommodate the circuit board 4, affecting the overall height of the battery housing 2.

[0024] This embodiment of the application provides an insulating component 1 within the battery pack 6, dividing the interior of the battery pack 6 into multiple storage areas 21. Each storage area 21 is used to store a battery module 3, allowing each battery module 3 to be stored independently, facilitating the assembly of the battery module 3. Furthermore, the insulating component 1, once installed inside the battery pack 6, also enhances the structural strength of the battery pack 6. The insulating component 1 includes a first side plate 11, a second side plate 12, and a bottom plate 13. The mounting groove 14 defined by the first side plate 11, the second side plate 12, and the bottom plate 13 can be used to mount the circuit board 4 of the battery pack 6, allowing the insulating component 1 to be reused as a mounting structure for the circuit board 4. This optimizes the layout of the circuit board 4 within the battery pack 6, thereby reducing the height of the battery pack 6.

[0025] Specifically, please refer to Figures 1 to 8 This application provides an insulating component 1. The insulating component 1 is applied to a battery pack 6 to divide the interior of the battery pack 6 into at least two storage areas 21 for storing battery modules 3. The insulating component 1 includes a first side plate 11 and a second side plate 12 disposed opposite to each other, and a bottom plate 13 connected between the first side plate 11 and the second side plate 12. The first side plate 11, the second side plate 12, and the bottom plate 13 together define a mounting groove 14. The mounting groove 14 is configured to mount a circuit board 4 of the battery pack 6.

[0026] Understandably, after the insulating component 1 is installed inside the battery pack 6, the internal space of the battery pack 6 can be divided into at least two storage areas 21. Each storage area 21 can hold one battery module 3, allowing the battery module 3 to be placed independently. The battery module 3 can either abut against the outer surface of the first side plate 11 and / or the second side plate 12, or it can be spaced slightly apart from the first side plate 11 and / or the second side plate 12. This ensures that each battery module 3 can be confined within its corresponding storage area 21.

[0027] After the insulating component 1 is installed inside the battery pack 6, its opposite sides abut against the opposite sides of the battery box 2, or the opposite sides of the insulating component 1 are spaced apart from the opposite sides of the battery box 2, thereby dividing the interior of the battery pack 6 into at least two storage areas 21. The upper and lower sides of the insulating component 1 are connected to the top and bottom of the battery box 2, respectively. Based on the connection between the insulating component 1 and the battery box 2, a certain supporting force can be provided to the battery box 2, thereby enhancing the structural strength of the battery pack 6.

[0028] The area formed by the first side plate 11, the second side plate 12, and the bottom plate 13 serves as a mounting groove 14, whereby the circuit board 4 of the battery pack 6 is placed, so that the circuit board 4 of the battery pack 6 is embedded in the insulating component 1. The circuit board 4 of the battery pack 6 is fixed to either the first side plate 11 or the second side plate 12.

[0029] In some embodiments, the first side plate 11 and the second side plate 12 have the same shape. That is, the length of the first side plate 11 is the same as the length of the second side plate 12, the height of the first side plate 11 is the same as the height of the second side plate 12, and the thickness of the first side plate 11 is the same as the thickness of the second side plate 12. Along the direction from the first side plate 11 to the second side plate 12, the projection of the first side plate 11 completely coincides with the projection of the second side plate 12.

[0030] In some embodiments, the first side plate 11 and the second side plate 12 have different shapes. For example, the length of the first side plate 11 is the same as the length of the second side plate 12, but the height of the first side plate 11 is different from the height of the second side plate 12.

[0031] In some embodiments, the opposite ends of the base plate 13 are respectively connected to the lower ends of the first side plate 11 and the second side plate 12, thereby forming a generally U-shaped insulating assembly 1. In this case, the mounting groove 14 defined by the first side plate 11, the second side plate 12 and the base plate 13 is located above the base plate 13.

[0032] In some embodiments, one end of the base plate 13 is connected to the region between the upper and lower ends of the first side plate 11, and the other end of the base plate 13 is connected to the region between the upper and lower ends of the second side plate 12. In this case, the mounting groove 14 defined by the first side plate 11, the second side plate 12, and the base plate 13 is located above or below the base plate 13.

[0033] In some embodiments, the opposite ends of the base plate 13 are respectively connected to the upper ends of the first side plate 11 and the second side plate 12, thereby forming a generally door-shaped insulating assembly 1. In this case, the mounting groove 14 defined by the first side plate 11, the second side plate 12 and the base plate 13 is located below the base plate 13.

[0034] In some embodiments, the circuit board 4 of the battery pack 6 includes a main control circuit board and a BMS (Battery Management System). The BMS includes a BMS circuit board and components integrated on the BMS circuit board.

[0035] like Figure 2 As shown, in some embodiments, one of the first side plate 11 and the second side plate 12 is provided with a mounting hole 15, and the circuit board 4 is configured to be fixed to the mounting hole 15 by a first fastener.

[0036] It is understandable that by opening mounting holes 15 on the first side plate 11 or the second side plate 12, and using the first fastener to pass through the plate hole and mounting hole 15 of the circuit board 4, the position of the circuit board 4 can be fixed.

[0037] In some embodiments, at least two circuit boards 4 may be provided. For example, two circuit boards 4 may be provided, namely a main control circuit board and a BMS. Each circuit board 4 may have multiple board holes, and the first side plate 11 or the second side plate 12 may also have multiple mounting holes 15 at corresponding positions.

[0038] In some embodiments, mounting holes 15 are formed in the first side plate 11.

[0039] In some embodiments, mounting holes 15 are formed in the second side plate 12.

[0040] In some embodiments, the first fastener includes screws, bolts, etc., in which case the wall surface of the mounting hole 15 has internal threads. The first fastener also includes rivets, pins, etc., in which case the first fastener can be interference-fitted into the mounting hole 15.

[0041] like Figure 2 As shown, in some embodiments, the other of the first side plate 11 and the second side plate 12 is provided with a clearance hole 16. Along the direction from the first side plate 11 to the second side plate 12, the projection of the mounting hole 15 lies within the projection of the clearance hole 16. The clearance hole 16 is configured to allow a first fastener and / or mounting tool to pass through.

[0042] Understandably, the distance between the first side plate 11 and the second side plate 12 is limited, resulting in a small groove width for the mounting slot 14 formed between them, barely wide enough to accommodate the circuit board 4. When the circuit board 4 is mounted from the top into the mounting slot 14, it is impossible to install the first fastener from the top, sides, or other areas of the mounting slot 14 to fix the circuit board 4 to the first side plate 11 or the second side plate 12. Therefore, a clearance hole 16 is constructed in the other of the first side plate 11 and the second side plate 12, through which the first fastener can pass to connect the circuit board 4 to the mounting hole 15. When the first fastener is a screw or other fastener requiring rotational fixation, an installation tool can also be inserted through the clearance hole 16 to rotate the first fastener, ensuring reliable fixation between the circuit board 4 and the mounting hole 15.

[0043] In some embodiments, the number and distribution of clearance holes 16 are exactly the same as the number and distribution of mounting holes 15. For example, if two circuit boards 4 are installed in the mounting slot 14, and each circuit board 4 corresponds to four mounting holes 15, then the clearance holes 16 are set to eight.

[0044] In some embodiments, both the clearance hole 16 and the mounting hole 15 are circular holes, and the diameter of the clearance hole 16 is larger than the diameter of the mounting hole 15. Furthermore, the diameter of the clearance hole 16 is also larger than the outer diameter of the first fastener.

[0045] In some embodiments, the first side plate 11 is provided with mounting holes 15, and the second side plate 12 is provided with clearance holes 16.

[0046] In some embodiments, the first side plate 11 is provided with a clearance hole 16, and the second side plate 12 is provided with a mounting hole 15.

[0047] like Figure 4 As shown, in some embodiments, the insulating assembly 1 further includes a cover plate 17. The cover plate 17 is connected to the end of the first side plate 11 and the second side plate 12 away from the bottom plate 13.

[0048] Understandably, the first side plate 11, the second side plate 12, and the bottom plate 13 can be joined to form a generally U-shaped insulating assembly 1, in which case the top of the mounting groove 14 has an opening. A cover plate 17 is connected to the top of the first side plate 11 and the second side plate 12, thereby closing the opening at the top of the mounting groove 14.

[0049] It should be noted that the first side plate 11, the second side plate 12, and the bottom plate 13 are connected in a U-shape, and the mounting groove 14 defined therein will have openings on the top and front and rear sides. The cover plate 17 only closes the opening on the top of the mounting groove 14. One of the openings on the front and rear sides of the mounting groove 14 can be used for the plug 5 to pass through, and the other can be used for the FPC or electrical connector to pass through.

[0050] like Figure 2 and Figure 5 As shown, in some embodiments, the first side plate 11 and / or the second side plate 12 are provided with a first positioning portion 18 on the side facing the cover plate 17. The cover plate 17 is provided with a second positioning portion 19 on the side facing the first side plate 11 and / or the second side plate 12. The first positioning portion 18 is connected to the second positioning portion 19.

[0051] It is understandable that by providing the first positioning part 18 and the second positioning part 19, the cover plate 17 can be positioned and installed, thereby achieving rapid positioning of the cover plate 17. After the cover plate 17 is pre-positioned and installed with the first side plate 11 and / or the second side plate 12 via the first positioning part 18 and the second positioning part 19, it can be further fixed and connected by fasteners such as screws to ensure the reliability of the connection between the cover plate 17 and the first side plate 11 and the second side plate 12.

[0052] In some embodiments, the cover plate 17 covers the top of the first side plate 11 and the second side plate 12. The upper surfaces of both the first side plate 11 and the second side plate 12 are provided with a first positioning portion 18. The lower surface of the cover plate 17 is provided with a second positioning portion 19.

[0053] In some embodiments, the cover plate 17 covers the top of the first side plate 11 and the second side plate 12. A first positioning portion 18 is provided on the upper surface of the first side plate 11. A second positioning portion 19 is formed on the lower surface of the cover plate 17 at a position corresponding to the first side plate 11.

[0054] In some embodiments, the cover plate 17 covers the top of the first side plate 11 and the second side plate 12. The upper surface of the second side plate 12 is provided with a first positioning portion 18. The lower surface of the cover plate 17 is provided with a second positioning portion 19 at a position corresponding to the second side plate 12.

[0055] like Figure 2 and Figure 5 As shown, in some embodiments, one of the first positioning part 18 and the second positioning part 19 includes a first positioning groove, and the other includes a positioning block. The positioning block is engaged within the first positioning groove.

[0056] It is understandable that by engaging the positioning block into the first positioning groove, the positioning connection between the first positioning part 18 and the second positioning part 19 is achieved, thereby enabling the cover plate 17 to quickly and accurately cover the top of the first side plate 11 and the second side plate 12.

[0057] In some embodiments, the upper surfaces of the first side plate 11 and the second side plate 12 are provided with a first positioning groove. The lower surface of the cover plate 17 is provided with a downwardly protruding positioning block. When the cover plate 17 is closed on the top of the first side plate 11 and the second side plate 12, the positioning block is engaged in the first positioning groove.

[0058] In some embodiments, the dimensions of the positioning block are the same as the dimensions of the first positioning groove. For example, the positioning block is square, and the first positioning groove is a square groove. In this case, the length of the positioning block is equal to the length of the first positioning groove; the width of the positioning block is equal to the width of the first positioning groove; and the thickness of the positioning block is equal to the groove depth of the first positioning groove. For example, the positioning block is cylindrical, and the first positioning groove is circular. In this case, the diameter of the positioning block is equal to the diameter of the first positioning groove, and the thickness of the positioning block is equal to the groove depth of the first positioning groove.

[0059] In some embodiments, the cover plate 17 is further provided with a first reinforcing rib and a second reinforcing rib protruding toward the first side plate 11 and the second side plate 12, thereby providing structural reinforcement to the cover plate 17. The first reinforcing rib and the second reinforcing rib can be spaced apart. The distance between the sides of the first reinforcing rib and the second reinforcing rib that are away from each other is equal to the width of the mounting groove 14. Thus, when the cover plate 17 is closed on the first side plate 11 and the second side plate 12, both the first reinforcing rib and the second reinforcing rib are located within the mounting groove 14, with the first reinforcing rib abutting against the inner wall of the first side plate 11 and the second reinforcing rib abutting against the inner wall of the second side plate 12.

[0060] When the cover plate 17 is provided with a first reinforcing rib and a second reinforcing rib, a positioning block can be connected to the side of the first reinforcing rib and the side away from each other. At this time, the upper surfaces of the first side plate 11 and the second side plate 12 are provided with a first positioning groove. When the cover plate 17 is closed on the first side plate 11 and the second side plate 12, the first reinforcing rib abuts against the inner wall of the first side plate 11, the second reinforcing rib abuts against the inner wall of the second side plate 12, and the positioning block on the outer side of the first reinforcing rib is engaged in the first positioning groove of the first side plate 11, and the positioning block on the outer side of the second reinforcing rib is engaged in the first positioning groove of the second side plate 12.

[0061] In some embodiments, the first side plate 11, the second side plate 12, and the bottom plate 13 are integrally formed.

[0062] It is understandable that the first side plate 11, the second side plate 12, and the bottom plate 13 are integrally molded, which makes the insulating component 1 easy to mold and has good connection strength. For example, the first side plate 11, the second side plate 12, and the bottom plate 13 are all plastic parts, and the first side plate 11, the second side plate 12, and the bottom plate 13 are integrally injection molded.

[0063] It should be noted that the cover plate 17 can also be made of plastic material.

[0064] like Figure 6 As shown, according to a second aspect of this application, a battery pack 6 is provided, which includes the insulating component 1 in the above embodiments. The battery pack 6 possesses all the beneficial effects of the insulating component 1, which will not be elaborated further here.

[0065] In some embodiments, the battery pack 6 further includes a battery compartment 2. An insulating component 1 is disposed within the battery compartment 2, dividing the battery compartment 2 into at least two storage areas 21. Each storage area 21 stores a battery module 3.

[0066] After the insulation component 1 is installed in the battery box 2, the internal area of ​​the battery box 2 can be divided into at least two storage areas 21, so that the battery modules 3 can be stored in different storage areas 21. This allows the battery modules 3 to be stored independently. Since each battery module 3 is independently installed in each storage area 21, there is no need to consider the arrangement and positioning of the battery modules 3 when installing them. The battery modules 3 can simply be placed in the storage area 21, which facilitates the assembly of the battery modules 3.

[0067] After the insulating component 1 is installed on the battery box 2, its upper and lower sides can be connected to the upper and lower sides of the battery box 2. The insulating component 1 can provide a certain supporting force to the battery box 2, thereby enhancing the structural strength of the battery pack 6. The insulating component 1 divides the interior of the battery box 2 into at least two storage areas 21 distributed to the left and right. Since the circuit board 4 is located inside the insulating component 1, it does not need to be placed on top of the battery module 3, thus optimizing the layout of the circuit board 4 and reducing the height of the battery pack 6.

[0068] It should be noted that the battery module 3 can abut against the outer surface of the first side plate 11 and / or the second side plate 12, or the battery module 3 can be spaced apart from the first side plate 11 and / or the second side plate 12 with a small gap.

[0069] In some embodiments, the insulating component 1 is arranged in a straight line. The insulating component 1 can divide the interior of the battery box 2 into two storage areas 21. Each storage area 21 can hold a battery module 3.

[0070] In some embodiments, at least two insulating components 1 may be provided inside the battery box 2, and the at least two insulating components 1 are spaced apart, thereby forming at least three storage areas 21 inside the battery box 2. Each storage area 21 may hold a battery module 3.

[0071] In some embodiments, the battery module 3 can also be bonded to the bottom surface of the battery box 2, the wall surface of the battery box 2, the first side plate 11, and the second side plate 12 by potting compound and structural adhesive to prevent the battery module 3 from moving around in the battery pack 6.

[0072] Please continue reading. Figure 8 In some embodiments, the insulating component 1 extends along a first direction. Along a second direction, the insulating component 1 is located at the center of the battery box 2. The first direction and the second direction are angled together.

[0073] It is understandable that by placing the insulating component 1 in the middle of the battery box 2, the insulating component 1 can divide the interior of the battery box 2 into two identical storage areas 21. This ensures that each battery module 3 has the same shape, facilitating the assembly of the battery modules 3, improving the error tolerance of the battery module 3 installation, and preventing the battery module 3 from being assembled into the wrong storage area 21.

[0074] The insulating component 1 extends along a first direction, and its two ends abut against the wall surfaces of the battery box 2 on opposite sides in the first direction. Alternatively, the insulating component 1 is spaced apart from the wall surfaces of the battery box 2 on opposite sides in the first direction.

[0075] It should be noted that the first direction and the second direction can be set at an acute angle. Alternatively, the first direction and the second direction can be set at a right angle. Or, the first direction and the second direction can be set at an obtuse angle. For example, the first direction is the width direction of the battery box 2, and the second direction is the length direction of the battery box 2.

[0076] The middle position of battery box 2 is: the axial position of battery box 2 in the length direction.

[0077] Please continue reading. Figure 6 and Figure 7 In some embodiments, the battery pack 6 further includes a plug 5. The plug 5 is mounted on the battery housing 2. One end of the plug 5 is located inside the battery housing 2 and is electrically connected to the battery module 3. The other end of the plug 5 is located outside the battery housing 2 and is configured to connect to electrical devices and / or charging devices.

[0078] It is understood that the battery module 3 is electrically connected to the power device and / or charging device via the plug 5, thereby enabling the charging and discharging of the battery module 3. The plug 5, located inside the battery box 2, may be connected to an electrical connector, which is electrically connected to the battery module 3. The plug 5, located outside the battery box 2, may be provided with a pin, which is used to plug into and electrically connect to the power device and / or charging device.

[0079] In some embodiments, the plug 5 has a certain degree of flexibility, allowing it to deform to some extent when plugged into electrical equipment and / or charging equipment. Since the insulating component 1 is located in the center of the battery compartment 2, the plug 5 is deformed to a relatively uniform degree by both sides after being plugged into the electrical equipment and / or charging equipment, preventing tilting during installation. This ensures a good insertion feel for the plug 5 and prevents the pins of the plug 5 from tilting and being damaged.

[0080] In some embodiments, the electrical equipment includes vehicles, such as vehicles, ships, and aircraft. The electrical equipment may also include weighing scales, body fat scales, nutrition scales, body composition analyzers, mobile terminals, and smart home devices. The electrical equipment also includes quadruped robots, bipedal robots, etc.

[0081] In some embodiments, the charging equipment includes charging piles, charging stations, etc.

[0082] like Figure 6 and Figure 7 As shown, in some embodiments, the battery box 2 has a connecting groove 22 at a position corresponding to the insulating component 1. The bottom surface of the connecting groove 22 has a through hole 23 that communicates with the mounting groove 14. The plug 5 is disposed in the connecting groove 22, and one end of the plug 5 passes through the through hole 23 into the mounting groove 14.

[0083] Understandably, the battery box 2 has an inwardly recessed wall surface at the location corresponding to the insulating component 1, forming a connection groove 22. This connection groove 22 can be used to connect the plug 5. Since the through hole 23 on the bottom surface of the connection groove 22 can connect to the mounting groove 14, when the plug 5 is installed in the connection groove 22, one end of the plug 5 can pass through the through hole 23 into the mounting groove 14 and connect with the electrical connector in the mounting groove 14 to form an electrical connection with the battery module 3 through the electrical connector. The other end of the plug 5 is located outside the connection groove 22 for connecting electrical equipment and / or charging equipment.

[0084] It should be noted that the plug 5 is inserted into the connecting slot 22 and connected to the wall of the battery box 2 by screws or other fasteners, so that the plug 5 is securely and reliably installed in the battery box 2.

[0085] like Figure 3 and Figure 7 As shown, in some embodiments, the battery box 2 includes a box body 24. A third positioning portion 25 is provided on the bottom surface of the box body 24. An insulating assembly 1 is disposed inside the box body 24. A fourth positioning portion 131 is provided on the bottom plate 13. The third positioning portion 25 and the fourth positioning portion 131 are connected.

[0086] Understandably, after the insulation component 1 is installed inside the housing 24, the base plate 13 will contact the bottom surface of the housing 24. By providing a third positioning part 25 on the bottom surface of the housing 24 and a fourth positioning part 131 on the base plate 13, the positioning assembly between the third positioning part 25 and the fourth positioning part 131 is used to ensure the installation accuracy of the insulation component 1 and to achieve rapid positioning and installation of the insulation component 1.

[0087] The bottom surface of the housing 24 may be provided with at least two third positioning parts 25, and the spacing direction of the at least two third positioning parts 25 is the same as the extension direction of the insulating component 1. The distribution position and number of the fourth positioning parts 131 on the base plate 13 are the same as the distribution position and number of the third positioning parts 25 on the bottom surface of the housing 24. By forming a multi-point positioning fit through at least two third positioning parts 25 and at least two fourth positioning parts 131, rotation of the insulating component 1 after positioning connection can be prevented, thus avoiding deviation in the installation position of the insulating component 1.

[0088] like Figure 3 and Figure 7 As shown, in some embodiments, one of the third positioning part 25 and the fourth positioning part 131 includes a second positioning post, and the other includes a second positioning groove. The second positioning post is disposed in the second positioning groove.

[0089] It is understandable that by engaging the second positioning post into the second positioning groove, the positioning connection between the third positioning part 25 and the fourth positioning part 131 is achieved, thereby enabling the insulating component 1 to quickly and accurately cover the bottom surface of the housing 24.

[0090] In some embodiments, the bottom surface of the housing 24 is provided with a second positioning groove. The lower surface of the base plate 13 is provided with a downwardly protruding second positioning post. When the insulating assembly 1 is installed inside the housing 24, the second positioning post is engaged in the second positioning groove.

[0091] In some embodiments, the bottom surface of the housing 24 is provided with a second positioning post. The lower surface of the base plate 13 is provided with a second positioning groove. When the insulating assembly 1 is installed inside the housing 24, the second positioning post engages with the second positioning groove.

[0092] In some embodiments, the dimensions of the second positioning post are the same as the dimensions of the second positioning groove. For example, the second positioning post is square, and the second positioning groove is a square groove. In this case, the length of the second positioning post is equal to the length of the second positioning groove; the width of the second positioning post is equal to the width of the second positioning groove; and the height of the second positioning post is equal to the depth of the second positioning groove. For example, the second positioning post is cylindrical, and the second positioning groove is circular. In this case, the diameter of the second positioning post is equal to the diameter of the second positioning groove, and the height of the second positioning post is equal to the depth of the second positioning groove.

[0093] Please continue reading. Figure 3 and Figure 7 In some embodiments, a connecting channel 251 is formed within the second positioning post. A connecting hole 132 is formed on the bottom surface of the second positioning groove. The connecting hole 132 and the connecting channel 251 are connected by a second fastener.

[0094] Understandably, after the bottom plate 13 of the insulation component 1 and the bottom surface of the housing 24 are connected by the second positioning post and the second positioning groove, the connecting hole 132 on the bottom surface of the second positioning groove is connected to the connecting channel 251 inside the second positioning post. At this time, the second fastener is sequentially inserted into the connecting hole 132 and the connecting channel 251 to achieve a stable and reliable connection between the insulation component 1 and the housing 24.

[0095] In some embodiments, the second fastener includes screws, bolts, etc., and the channel wall of the connecting channel 251 is configured with internal threads that match the second fastener.

[0096] It should be noted that after the insulating component 1 is fixed inside the housing 24 using the second fastener and installation tool, the cover plate 17 is then placed on top of the first side plate 11 and the second side plate 12. Therefore, it is unnecessary to create clearance holes in the cover plate 17 for the second fastener and installation tool to pass through.

[0097] Please continue reading. Figure 5 and Figure 7In some embodiments, the battery box 2 further includes a cover 26. The cover 26 is connected to the box body 24. A fifth positioning portion 27 is provided on the side of the cover 26 facing the insulating assembly 1. A sixth positioning portion 171 is provided on the cover plate 17 of the insulating assembly 1. The fifth positioning portion 27 is connected to the sixth positioning portion 171.

[0098] Understandably, through the positioning cooperation of the fifth positioning part 27 and the sixth positioning part 171, the positioning and assembly of the cover 26 can be achieved, and the cover 26 can be connected to the cover plate 17 of the insulating component 1. Since the bottom plate 13 of the insulating component 1 is connected to the bottom plate 13 of the box body 24 through the third positioning part 25 and the fourth positioning part 131, and the cover plate 17 of the insulating component 1 is connected to the cover 26 through the fifth positioning part 27 and the sixth positioning part 171, the position of the insulating component 1 can be effectively fixed, preventing the position of the insulating component 1 inside the battery pack 6 from shifting during use. Thus, the insulating component 1 is stably set inside the battery box 2, so that the insulating component 1 can effectively support the battery box 2, thereby improving the structural strength of the battery box 2. Furthermore, being stably set inside the battery box 2 can also keep the size of the storage area 21 inside the battery box 2 basically unchanged, thereby reducing the possibility of the battery module 3 shifting.

[0099] like Figure 3 and Figure 7 As shown, in some embodiments, one of the fifth positioning part 27 and the sixth positioning part 171 includes a third positioning post, and the other includes a positioning hole. The third positioning post is disposed in the positioning hole.

[0100] It is understandable that by engaging the third positioning post into the positioning hole, the positioning connection between the fifth positioning part 27 and the sixth positioning part 171 is achieved, thereby enabling the cover 26 to quickly and accurately close onto the box body 24, and connecting the cover 26 with the cover plate 17 of the insulating component 1.

[0101] In some embodiments, the lower surface of the cover 26 is provided with a positioning hole. The upper surface of the cover plate 17 is provided with an upwardly protruding third positioning post. When the cover 26 is closed inside the box body 24, the third positioning post is engaged in the positioning hole.

[0102] In some embodiments, the lower surface of the housing 24 is provided with a downwardly protruding third positioning post. The upper surface of the cover plate 17 is provided with a positioning hole. When the cover 26 is closed inside the housing 24, the third positioning post engages with the positioning hole.

[0103] In some embodiments, the dimensions of the third positioning post are the same as the dimensions of the positioning hole. For example, the third positioning post is a square post, and the positioning hole is a square hole. In this case, the length of the third positioning post is equal to the length of the positioning hole; the width of the third positioning post is equal to the width of the positioning hole; and the height of the third positioning post is equal to the depth of the positioning hole. For example, the third positioning post is cylindrical, and the positioning hole is circular. In this case, the diameter of the third positioning post is equal to the diameter of the positioning hole, and the height of the third positioning post is equal to the depth of the positioning hole.

[0104] According to a third aspect of this application, an electrical device is provided, which includes the battery pack 6 in the above embodiments. The electrical device has all the beneficial effects of the battery pack 6, which will not be repeated here.

[0105] In some embodiments, electrical equipment includes vehicles, such as vehicles, ships, airplanes, etc. Electrical equipment may also include weighing scales, body fat scales, nutrition scales, body composition analyzers, mobile terminals, and smart home devices. Electrical equipment also includes quadruped robots, bipedal robots, etc.
