[0028] In the description of this application, unless otherwise specified or limited, the terms "connected," "connect," and "fixed" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integration; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; and can refer to internal communication between two components or interaction between two components. Those skilled in the art will understand the specific meanings of the above terms in this application based on the specific circumstances.

[0029] In this application, unless otherwise expressly specified or limited, a first feature being "above" or "below" a second feature may include the first and second features being in direct contact, or may include the first and second features being in contact not directly but through another feature between them. Moreover, a first feature being "above," "above," and "above" a second feature may include the first feature being directly above or obliquely above the second feature, or may simply mean that the first feature is higher in level than the second feature. A first feature being "below," "below," and "below" a second feature may include the first feature being directly below or obliquely below the second feature, or may simply mean that the first feature is lower in level than the second feature.

[0030] In the description of this embodiment, the terms "upper," "lower," "right," and other orientations or positional relationships are based on the orientations or positional relationships shown in the accompanying drawings and are intended solely for ease of description and simplified operation. They do not indicate or imply that the devices or components referred to must have a specific orientation, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on this application. Furthermore, the terms "first" and "second" are used solely for descriptive purposes and have no special meanings.

[0031] As shown in FIG1 , an embodiment of the present application provides a wiring harness isolation plate, which includes a plurality of isolation plate units 10 and a connection structure. The plurality of isolation plate units 10 are sequentially connected along a first direction, and the connection structure is arranged between every two adjacent isolation plate units 10. The connection structure includes a first connector 21 and a second connector 22. The first connector 21 and the second connector 22 are respectively located at the ends of the two adjacent isolation plate units 10 facing each other. A first mounting groove 212 is provided on the first connector 21. The first connector 21 also includes a first buckle 211. The first buckle 211 is arranged in the first mounting groove 212 and is spaced apart from the inner wall of the first mounting groove 212 extending along the third direction. The first The buckle 211 can be deformed along the third direction relative to the first mounting groove 212; the second connecting member 22 includes a receiving portion 221 and a second buckle 222, the projection of the second buckle 222 along the second direction is located on the receiving portion 221, and the second buckle 222 is adapted to the shape of the first buckle 211, and the extension lines between the first direction, the second direction and the third direction have an angle; wherein, when the first connecting member 21 and the second connecting member 22 are connected to each other, the receiving portion 221 is located in the first mounting groove 212, and the first buckle 211 is engaged with the second buckle 222 by swinging.

[0032] By applying the technical solution of the present application, the wiring harness isolation plate is configured to be composed of multiple isolation plate units 10, and the multiple isolation plate units 10 are detachably connected through a connecting structure. This configuration can reduce the mold size of the wiring harness isolation plate, thereby reducing the mold processing cycle, processing cost and processing difficulty. At the same time, the connecting structure includes a first connecting member 21 and a second connecting member 22. The first connecting member 21 and the second connecting member 22 are snap-fitted to achieve rapid assembly and disassembly between components, thereby reducing the difficulty of disassembly between the isolation plate units 10, thereby helping to improve the disassembly efficiency of the device.

[0033] In the embodiment of the present application, X represents the length of the wiring harness isolation plate, Y represents the width of the wiring harness isolation plate, and Z represents the height of the wiring harness isolation plate. Furthermore, the first buckle 211 is elastic. When assembled with the second buckle 222, the first buckle 211 and the second buckle 222 form an interference fit, which allows the first buckle 211 to elastically deform and swing along the third direction. Once assembled, the first buckle 211 returns to its original shape under the action of elasticity and engages with the second buckle 222.

[0034] At the same time, the second clip 222 in the present application is fixedly connected to the receiving portion 221. In this way, during installation, it is only necessary to elastically deform the first clip 211, thereby ensuring the strength of the connection between the first connecting member 21 and the second connecting member 22. Of course, the second clip 222 can also be configured not to be fixedly connected to the receiving portion 221, so that both the first clip 211 and the second clip 222 are relatively elastically deformed during assembly, thereby increasing the assembly speed of the two. The specific configuration should be selected according to the user's usage requirements, as long as it can meet the connection requirements between the components.

[0035] As shown in Figures 2 and 3, the first buckle 211 has a first section 2111 and a second section 2112 that are sequentially connected and arranged at an angle, and the second buckle 222 has a third section 2221 and a fourth section 2222 that are sequentially connected and arranged at an angle. The first section 2111 and the third section 2221 extend in a first direction, while the second section 2112 and the fourth section 2222 extend in opposite directions. When the first connector 21 and the second connector 22 are connected to each other, the second section 2112 and the fourth section 2222 engage with each other. This arrangement ensures that when the first buckle 211 and the second buckle 222 are assembled, the mutual engagement of the second section 2112 and the fourth section 2222 allows the first buckle 211 and the second buckle 222 to perfectly fit together, thereby improving the stability of the connection between the components.

[0036] Specifically, in the embodiment of the present application, the structures of the first section 2111 and the third section 2221 are the same, and the structures of the second section 2112 and the fourth section 2222 are also the same. This can further improve the assembly fit between the first buckle 211 and the second buckle 222, thereby improving the structural strength after the first buckle 211 and the second buckle 222 are connected.

[0037] In addition, a reducing section is provided at the connection between the first section 2111 and the first connecting member 21, and at the connection between the third section 2221 and the second connecting member 22, and the width of the reducing section gradually decreases from the first connecting member 21 toward the first section 2111 and decreases from the second connecting member 22 toward the third section 2221. By setting the above structure, the reducing section can improve the structural strength when the first section 2111 and the first connecting member 21 and the third section 2221 are connected to the second connecting member 22, thereby avoiding the first clip 211 and the second clip 222 from breaking due to excessive force when connected. This can further ensure the stability of the two, which is conducive to maintaining the normal operation of the device.

[0038] Furthermore, the first connector 21 includes at least two first clips 211, which are spaced apart along the third direction and symmetrically arranged along the first direction. This arrangement, utilizing two clips, can further improve the connection stability between the first connector 21 and the second connector 22. Simultaneously, arranging the two clips in a symmetrical manner can also ensure a more balanced force on the first connector 21 and the second connector 22 during connection. In an embodiment of the present application, the second sections 2112 of the two first clips 211 are arranged facing away from each other. Alternatively, the second sections 2112 of the two first clips 211 can also be arranged facing each other, as long as the connection requirements of the device are met.

[0039] Specifically, a limiting structure is provided between the first connector 21 and the second connector 22. When the receiving portion 221 is located within the first mounting groove 212, the limiting structure can limit the displacement of the first connector 21 relative to the second connector 22 along the second direction. By providing this structure, when the first connector 21 and the second connector 22 are connected, the limiting structure can prevent relative displacement between them, thereby preventing the risk of adjacent isolation panel units 10 falling off during operation of the device. This ensures the normal operation of the device and meets the user's usage needs.

[0040] Furthermore, a first protrusion 31 is provided on the inner wall of the first mounting groove 212 extending along the first direction. The surface of the first protrusion 31 is arranged to protrude from the inner wall of the first mounting groove 212 along the third direction. The side wall of the second clip 222 away from the first clip 211 cooperates with the side wall of the receiving portion 221 close to the second clip 222 to form a first matching portion 32. The first protrusion 31 and the first matching portion 32 cooperate with each other to form a limiting structure. This arrangement not only meets the limiting requirements of the device, but also has a simple structure, which not only facilitates the processing of the components, but also does not occupy additional space, thereby reducing production costs and reducing the overall volume of the device, which is conducive to the miniaturization of the device.

[0041] In the present application, the projection of the first buckle 211 on the first connector 21 along the third direction coincides with the first protrusion 31. Of course, in other embodiments of the present application, the first buckle 211 can also be configured to be non-coplanar with the first protrusion 31 along the third direction. The specific configuration should be selected based on the use requirements of the device, as long as it can meet the assembly requirements of the device, thereby improving the practicality and applicability of the device.

[0042] At the same time, in this embodiment, the projected portions of the first clip 211 and the first protrusion 31 in the first mounting groove 212 along the second direction are hollowed out. This not only reduces the overall weight of the device to achieve the lightweight requirement of the device, but also reduces the use of materials in the production process to further reduce the production cost of the device, thereby facilitating mass production of the device.

[0043] Among them, when the first clip 211 and the second clip 222 are assembled, the two adjacent isolation plate units 10 can be limited in the first direction and the third direction, so that the two adjacent isolation plate units 10 can be prevented from displacing each other as much as possible, thereby ensuring the structural stability of the device after assembly.

[0044] As shown in Figures 4 and 5 , multiple connection structures are provided between each two adjacent isolation panel units 10, and the multiple connection structures are spaced apart along the third direction. This arrangement can maximize the stability of the adjacent isolation panel units 10 after connection, and can also ensure the structural strength of the connection. In the present application, a first connection member 21 is provided at the upper end of one isolation panel unit 10, and a second connection member 22 is provided at the lower end. The corresponding second connection member 22 is provided at the upper end of another adjacent isolation panel unit 10, and the corresponding first connection member 21 is provided at the lower end.

[0045] As shown in FIG1 , another embodiment of the present application provides an information acquisition assembly, which includes the aforementioned wiring harness isolation plate, a plurality of busbars 40, and a flexible circuit board 41. The plurality of busbars 40 are spaced apart along a first direction on the isolation plate unit 10 of the wiring harness isolation plate, with the two ends of each busbar 40 respectively fixed to two adjacent isolation plate units 10. The flexible circuit board 41 is disposed on the wiring harness isolation plate and electrically connected to the busbar 40. In the embodiment of the present application, the two ends of the busbar 40 are fixedly connected to the two adjacent isolation plate units 10 by heat riveting. This not only further improves the connection strength of the two adjacent isolation plate units 10, but also improves the connection accuracy of the isolation plate units 10 by using the heat riveting holes on the busbar 40 to position the heat riveting studs of the two adjacent isolation plate units 10, thereby reducing dimensional errors during assembly and improving the structural consistency of the multiple isolation plate units 10 after assembly.

[0046] Of course, in other embodiments of the present application, the busbar 40 may also be connected to the isolation plate unit 10 in other connection modes such as threaded connection or clip connection, as long as the assembly requirements of the device can be met.

[0047] As shown in Figures 6 to 8, the information collection assembly also includes a fixing member, which is disposed on the wiring harness isolation plate and is used to secure the module collection connector. The fixing member includes a socket 51 for fixedly connecting to the module collection connector, a cover 52, and a base 53. The cover 52 is disposed on the base 53. The base 53 has a guide groove 531 extending in the second direction, and the socket 51 is movably disposed within the guide groove 531. During assembly, the module collection connector is first fixedly connected to the socket 51, and then the socket 51 is pushed along the guide groove 531 to completely install the socket 51 within the base 53. This protects the module collection connector with the fixing member, preventing droplets from directly contacting the module collection connector during operation, which could cause a short circuit in the module collection connector. This ensures stable operation of the module collection connector, thereby facilitating normal operation of the device.

[0048] Specifically, the cover 52 and base 53 are detachably connected, and the base 53 and the wiring harness isolation plate are integrally formed. This structure facilitates the removal and installation of the cover 52 and base 53, thereby improving assembly and removal efficiency. The integral structure also enhances the connection strength between the base 53 and the wiring harness isolation plate, thereby ensuring stability during operation.

[0049] Another embodiment of the present application provides a battery module, which includes a battery pack and the above-mentioned information acquisition component, wherein the battery pack is electrically connected to the information acquisition component. The structure of the information acquisition component has been described in the above embodiment and will not be repeated here.

[0050] As shown in FIG6 , the fixing member further includes a first limiting structure 60, which is disposed between the receiving member 51 and the wall of the accommodating cavity 501; wherein, when the receiving member 51 is located in the initial position, the receiving member 51 can be fixedly connected to the acquisition connector; when the receiving member 51 is located in the installation position, the first limiting structure 60 can limit the displacement of the receiving member 51 relative to the accommodating cavity 501 along the second direction, and the extension line of the first direction is perpendicular to the second direction.

[0051] As shown in FIG9 , the first limiting structure 60 includes a limiting protrusion 61 and a limiting groove 62. The limiting protrusion 61 is provided on one of the bottom walls of the accommodating cavity 501 or the corresponding bottom wall of the receiving member 51, and the limiting groove 62 is provided on the other of the bottom walls of the accommodating cavity 501 or the corresponding bottom wall of the receiving member 51. When the receiving member 51 is in the installed position, the limiting protrusion 61 and the limiting groove 62 engage with each other to limit the displacement of the receiving member 51. This arrangement not only satisfies the limiting requirement of the first limiting structure 60 on the receiving member 51, but also is simple and easy to manufacture, thereby reducing the difficulty of producing the assembly and the production cost of the device.

[0052] As shown in Figures 7 and 8, the housing 50 includes a cover 52 and a base 53. The cover 52 has a first connection portion, and the base 53 has a second connection portion. The cover 52 is removably connected to the base 53 through the cooperation of the first and second connection portions. The cover 52 and base 53 are connected to form a receiving cavity 501 and an opening 512. The limiting protrusion 61 is located on the base 53. The housing 50 is configured as a split structure. When the collection connector needs to be installed or removed, the cover 52 and base 53 are first removed and separated. Then, the receiving member 51 can be separated from or connected to the collection connector. This facilitates assembly and disassembly of the device, thereby improving the efficiency of device replacement.

[0053] Among them, in the embodiment of the present application, the limiting protrusion 61 is specifically an elastic boss structure, the height of the boss part of the elastic boss is higher than the bottom wall height of the base 53, the limiting groove 62 is specifically a rectangular slot, and the rectangular slot is set through the receiving part 51. When the receiving part 51 moves in the accommodating cavity 501, the receiving part 51 will exert downward pressure on the elastic boss, causing the boss to bend downward. When the receiving part 51 continues to move to the installation position, the elastic boss can rebound to its initial state, and the elastic boss can be engaged with the rectangular slot. At this time, the movement of the receiving part 51 can be limited, thereby ensuring the stable installation of the receiving part 51 in the installation position. The elastic boss can be set to be integrally formed with the bottom plate, so that the installation of the receiving part 51 can be completed without hot riveting or rivets, and it is also convenient for the disassembly of the receiving part 51, which not only improves the disassembly and assembly efficiency of the receiving part 51, but also the above structure is simple and can reduce the production cost of the device.

[0054] Furthermore, a guide groove 531 is provided on the inner wall of the first side or the second side of the base 53 extending along the second direction, or a guide groove 531 is provided on the inner walls of both sides of the base 53 extending along the second direction. The guide groove 531 extends along the second direction, and the receiving member 51 can move along the guide groove 531. In the embodiment of the present application, the guide grooves 531 are provided on the inner walls of both sides of the base 53 extending along the second direction. In this way, during the installation process of the receiving member 51, the guide grooves 531 on both sides can guide the movement of the receiving member 51, thereby reducing the possibility of deviation of the receiving member 51 during movement, thereby maintaining the linear movement of the receiving member 51, thereby improving the movement efficiency of the receiving member 51, and further facilitating the user's movement operation of the receiving member 51.

[0055] Specifically, the first connecting portion includes a first hook 131, which is disposed on a side of the cover 52 away from the opening 512. The second connecting portion includes a first slot 542 corresponding to the first hook 131. The first hook 131 engages with the first slot 542 to limit displacement of the cover 52 relative to the base 53 along the first direction. In the embodiment of the present application, the first slot 542 is disposed on the side wall of the base 53 away from the opening 512, and the first slot 542 extends through the side wall of the base 53 along the second direction. This structure facilitates the engagement of the first hook 131 with the first slot 542. Furthermore, the first slot 542 has sufficient depth to engage with the first buckle, thereby increasing the strength of the connection between the two and thereby improving the stability of the connection between the cover 52 and the base 53.

[0056] Optionally, the first card slot 542 can also be set to a semi-open slot form, and the notch of the first card slot 542 corresponds to the first hook 131. The specific setting should be selected according to the use environment of the device, which can improve the applicability and scope of application of the device to meet the user's usage needs in different scenarios.

[0057] In the embodiment of the present application, the first connection portion further includes a second hook 532, which is disposed on the sidewalls of the first and second sides of the cover 52 extending along the second direction. The second connection portion further includes a second slot 543 corresponding to the second hook 532. The second hook 532 engages with the second slot 543 to limit displacement of the cover 52 relative to the base 53 along the third direction. With the above structure, after the first hook 131 engages with the first slot 542, the second hook 532 engages with the second slot 543 to limit displacement of the cover 52 and the base 53 along the third direction. This prevents the cover 52 and the base 53 from sliding relative to each other after connection, which could cause the cover 52 to fall off. This further improves the stability of the connection between the cover 52 and the base 53.

[0058] At the same time, the first hook 131 and the second hook 532 in the present application are respectively integrally formed with the cover body 52. ​​This arrangement not only reduces the processing difficulty of the device, thereby reducing the production cost of the device, but also makes the overall cover body 52 more beautiful, thereby improving the overall image of the product.

[0059] Furthermore, the first connecting portion includes a plurality of first hooks 131, and the second connecting portion includes a plurality of first slots 542. The plurality of first hooks 131 and the plurality of first slots 542 are spaced apart along the first direction, and the first hooks 131 and the first slots 542 are provided in a one-to-one correspondence. This arrangement can further reduce the possibility of displacement of the cover 52 relative to the base 53 along the first direction, while also increasing the strength of the connection between the cover 52 and the base 53 to prevent separation of the cover 52 and the base 53 during use. In the present application, two first hooks 131 are provided, which not only meets the usage requirements of the device but also reduces the production cost of the device accordingly, thereby facilitating mass production of the device.

[0060] Specifically, the first hook 131 includes a first connecting segment 5311 and a second connecting segment 5312, which are sequentially connected and arranged at an angle. The second hook 532 includes a third connecting segment 5321 and a fourth connecting segment 5322, which are sequentially connected and arranged at an angle. The angle between the first connecting segment 5311 and the second connecting segment 5312 is the same as the angle between the third connecting segment 5321 and the fourth connecting segment 5322. This arrangement facilitates the processing of the components during production, thereby further reducing the processing difficulty and production cost of the device. In this embodiment, the angles between the first connecting segment 5311 and the second connecting segment 5312 and the third connecting segment 5321 and the fourth connecting segment 5322 are all set to . Optionally, in other embodiments, the above-mentioned angle can also be set to other angles, such as °, ° or °, etc., as long as it can meet the assembly requirements of the device. Of course, the angle between the first connecting segment 5311 and the second connecting segment 5312 and the angle between the third connecting segment 5321 and the fourth connecting segment 5322 can also be set to be different. The specific setting should be selected according to the use environment of the device, which can further improve the human applicability and scope of application of the device.

[0061] Furthermore, the information collection assembly also includes a second limiting structure 70, which is located between the cover 52 and the base 53. The second limiting structure 70 can limit the displacement of the cover 52 relative to the base 53 along the second direction. The second limiting structure 70 includes a protrusion 534 and a recessed portion 544. The protrusion 534 is located on the side of the cover 52 away from the opening 512, and the extension direction of the protrusion 534 is the same as the extension direction of the first connecting section 5311. The recessed portion 544 is located on the base 53 and is corresponding to the protrusion 534. The recessed portion 544 is formed by the two side walls of the base 53. When the cover 52 and the base 53 are connected, the protrusion 534 and the recessed portion 544 cooperate with each other to limit the displacement of the cover 52 and the base 53 along the second direction. This not only meets the limiting requirements of the device, but also reduces the processing cost of the device.

[0062] Specifically, the inner wall of the cover 52 facing the base 53 further includes an escape groove 533. When the receiving member 51 is in the installed position, a portion of the collection connector is located within the escape groove 533. Since the collection connector protrudes beyond the receiving member 51 after being mounted and fixed to the receiving member 51, the escape groove 533 provided on the cover 52 prevents interference between the receiving member 51 and the cover 52 when in the installed position, thereby protecting the collection connector's structure and extending its service life.
