Description

Technical Field

[0001] This utility model relates to the field of energy storage technology, and in particular to a wire harness assembly and an energy storage device. Background Technology

[0002] In current high-power power transmission applications, to meet high energy demands, multiple battery packs are typically connected in series or parallel using wiring harnesses. This connection method not only provides the necessary voltage and current but also allows for flexible adjustment of the total battery pack capacity according to actual needs. To ensure the safety and stability of such high-voltage, high-current transmission systems, the industry commonly uses protective conduits to house the wiring harnesses. This method effectively protects the wiring harnesses from external environmental factors such as moisture, corrosive substances, and physical damage, thereby reducing the risk of short circuits or other electrical faults.

[0003] However, in traditional installation processes, steel pipes need to be cut on-site, and the wiring harnesses manually threaded through the pipes and connected to the battery pack, making the entire installation process extremely cumbersome. First, cutting steel pipes on-site is not only time-consuming and labor-intensive, but also makes it difficult to guarantee cutting accuracy. Second, threading the wiring harnesses into the steel pipes is also a challenge, especially when facing long distances or complex routes, potentially requiring multiple attempts to successfully complete the wiring. These problems significantly reduce the installation efficiency of the battery packs, increase labor and time costs, and also impose additional operational difficulties and technical requirements on construction personnel. Utility Model Content

[0004] In view of the above-mentioned shortcomings of the existing technology, the technical problem to be solved by this utility model is to propose an integrated wire harness assembly that is easy to assemble and an energy storage device using the wire harness assembly.

[0017] A wiring harness assembly is disposed between the two battery packs. The assembly includes a wiring harness, a protective tube, and connectors. The protective tube includes a mounting cavity extending along its length, and the wiring harness is disposed within the mounting cavity. The connectors include a first connector and a second connector respectively located at both ends of the mounting cavity. The first and second connectors have conductive ends at their ends facing away from the mounting cavity, and these conductive ends are pluggable into the socket structure. When the conductive ends of the first and second connectors are respectively connected to the two socket structures, the two battery packs are electrically connected through the wiring harness.

[0018] Furthermore, the socket structure is detachably embedded in the battery pack, with a wiring terminal located inside the battery pack on one side and a mounting groove on the other side. The mounting groove is pluggable to the conductive end, and a first mounting hole is provided in the mounting groove. The first connector and the second connector are respectively provided with a second fixing hole corresponding to the first mounting hole. When the second fastener is sequentially inserted into the second fixing hole and the first mounting hole, the wiring harness assembly can be fixed on the battery pack.

[0037] like Figures 1 to 4 As shown, in this embodiment, a wiring harness assembly is installed between at least two battery packs 600, the wiring harness assembly comprising:

[0038] Wire harness 100;

[0039] The protective tube 200 includes a mounting cavity 210 that extends along the length of the protective tube 200, and the wire harness 100 is disposed in the mounting cavity 210.

[0040] The connector includes a first connector 300 and a second connector 400 respectively located at both ends of the mounting cavity 210. Each of the first and second connectors 300 has a conductive end 313 at its end facing away from the mounting cavity 210. The conductive end 313 is plugged into and detached from the battery pack 600. When the conductive ends 313 of the first and second connectors 300 are connected to the two battery packs 600 respectively, the two battery packs 600 are electrically connected through the wiring harness 100. This design achieves a quick plug-and-play connection of the wiring harness assembly, avoiding the steps of cutting steel pipes and manually threading wires on site, significantly reducing installation time and workload, and improving installation efficiency.

[0041] Specifically, in this embodiment, the wiring harness assembly is mainly used to realize the series or parallel connection between the two battery packs 600 to meet different voltage and current output requirements.

[0042] like Figures 1 to 4 As shown, in this embodiment, the wiring harness assembly includes a wiring harness 100, a protective tube 200, and a connector. The wiring harness 100 consists of multiple conductors, the number and specifications of which can be selected according to actual application needs to ensure it can carry the expected current intensity and meet voltage requirements. Furthermore, each conductor is wrapped with insulating material to prevent short circuits and other electrical faults.

[0043] In this embodiment, the wire harness 100 is fixed inside the protective tube 200. Through its integration with the protective tube 200, the wire harness 100 is not only effectively protected by physical means, but also eliminates the need for operators to manually thread the wires on site, effectively reducing the workload of on-site assembly and lowering the installation difficulty and time cost.

[0044] In this embodiment, the protective tube 200 is used to protect the internal wire harness 100 from the influence of the external environment. It is a hollow flexible steel tube. This design not only solves the problem that traditional rigid tubes are difficult to adapt to complex wiring paths, but also takes into account the needs of efficient protection and convenient maintenance of the wire harness 100, significantly improving the safety, reliability and engineering applicability of the wire harness assembly.

[0045] In this embodiment, the protective tube 200 includes a cylindrical mounting cavity 210 for accommodating the wire harness 100. The mounting cavity 210 extends along the length of the protective tube 200 and is adapted to the length of the protective tube 200, and both ends of the mounting cavity 210 are connected to the outside. It should be noted that the length of the protective tube 200 can be set according to the actual application requirements.

[0046] In this embodiment, the protective tube 200 has a first connector 220 and a second connector 230 at both ends. The first connector 220 is detachably connected to the first connector 300, and the second connector 230 is detachably connected to the second connector 400. This design allows the protective tube 200, the first connector 300, and the second connector 400 to be replaced and maintained independently, avoiding the need to replace the entire wiring harness assembly when a local structure is damaged, effectively reducing maintenance costs.

[0047] In this embodiment, the detachable connection between the first connector 220, the second connector 230, and the first connector 300 and the second connector 400 is a threaded connection, a snap-fit ​​connection, or a pin connection, to meet the requirements for connection strength, installation efficiency, and maintenance convenience under different working conditions. Preferably, the first connector 220 is threaded to the first connector 300, and the second connector 230 is threaded to the second connector 400. This design not only ensures the stability and reliability of the connection structure but also effectively prevents loosening of the connection due to external vibration or mechanical impact, thereby improving the safety and durability of the entire wiring harness assembly.

[0048] It is worth noting that in this embodiment, after the first connector 220 and the second connector 230 are connected to the first connector 300 and the second connector 400, the wire harness 100 can form an electrical connection with the first connector 300 and the second connector 400.

[0049] In this embodiment, a locking nut is fixedly provided at one end of the first connector 220 and the second connector 230 near the connector head, and the first connector 220 and the second connector 230 are threadedly connected to the first connector head 300 and the second connector head 400 through the locking nut.

[0050] In this embodiment, the connector serves as a transition structure for connecting the wiring harness 100 to the battery pack 600. It includes a first connector 300 and a second connector 400 connected to both ends of the protective tube 200, respectively. Each of the first connector 300 and the second connector 400 has a conductive end 313 at the end facing away from the mounting cavity 210, for plugging and unplugging connection with the battery pack 600, enabling electrical connection between the two battery packs 600. This design achieves a fast and reliable electrical connection while facilitating on-site installation and maintenance.

[0051] In this embodiment, the first connector 300 and the second connector 400 have the same structure, both including a separately configured base 310 and a cover 320. This design simplifies the manufacturing process through a standardized structure and improves the convenience of use and maintenance; at the same time, the detachable design of the base 310 and the cover 320 facilitates quick inspection and maintenance of the connector's internal components.

[0052] In this embodiment, the base 310 and the cover 320 are each provided with a corresponding first fixing hole 311 near the end of the protective tube 200. A first fastener 312 is detachably provided in the first fixing hole 311, and the base 310 and the cover 320 are detachably connected by the first fastener 312. Preferably, the first fixing hole 311 is a threaded hole, and the first fastener 312 is a bolt. This design ensures the ease of assembly and disassembly of the base 310 and the cover 320.

[0053] In this embodiment, the conductive end 313 is located on the side of the base 310 opposite to the cover 320, and a circumferentially arranged sealing structure 315 is provided on the outer side of the base 310. This sealing structure 315 is a sealing ring, and multiple such rings are present. When the connector is inserted into the socket structure 700 of the battery pack 600, the sealing ring abuts against the inner wall of the socket structure 700. This design prevents external dust and moisture from entering through the gap between them, ensuring the airtightness of the connection between the connector and the battery pack 600, thereby improving safety during use.

[0054] In this embodiment, the base 310 and the cover 320 are respectively provided with corresponding second fixing holes 314 at the ends away from the protective tube 200. Second fasteners (not shown in the figure) are detachably provided in the second fixing holes 314, and the connector is detachably connected to the socket structure 700 of the battery pack 600 through the second fasteners. This design ensures that the wiring harness assembly can be securely fixed after being plugged into the battery pack 600.

[0055] like Figures 1 to 6As shown, this embodiment of the present invention also provides an energy storage device, comprising:

[0056] The battery pack 600 is provided in at least two parts, and each of the two battery packs 600 is provided with a socket structure 700.

[0057] A wiring harness assembly, located between two battery packs 600, includes a wiring harness 100, a protective tube 200, and connectors. The protective tube 200 includes a mounting cavity 210 extending along its length, within which the wiring harness 100 is disposed. The connectors include a first connector 300 and a second connector 400 located at opposite ends of the mounting cavity 210. Each connector has a conductive end 313 at its end facing away from the mounting cavity 210, and these conductive ends 313 are pluggable into a socket structure 700. When the conductive ends 313 of the first connector 300 and the second connector 400 are connected to the two socket structures 700, the two battery packs 600 are electrically connected via the wiring harness 100. This design achieves quick pluggable connection through a prefabricated wiring harness assembly, greatly simplifying the installation process. It should be noted that the structure of the wiring harness assembly in this energy storage device is the same as the aforementioned wiring harness assembly structure, and will not be repeated here.

[0058] In this embodiment, the socket structure 700 is rectangular and detachably embedded in the side wall of the battery pack 600. One side has a wiring terminal 710 located inside the battery pack 600, and the other side has a mounting groove 720 recessed into the battery pack 600. This mounting groove 720 is pluggable to the conductive end 313, and a first mounting hole 721 is provided within the mounting groove 720. The first connector 300 and the second connector 400 are respectively provided with second fixing holes 314 corresponding to the first mounting hole 721. When a second fastener (not shown) is sequentially inserted into the second fixing hole 314 and the first mounting hole 721, the wiring harness assembly can be fixed to the battery pack 600. This design allows the wiring harness assembly to be quickly installed on the battery pack 600 via a pluggable method, and then quickly fixed by the second fastener, ensuring the stability of the wiring harness assembly installation.

[0059] Preferably, the first mounting hole 721 and the second fixing hole 314 are threaded holes, and the second fastener is a bolt. This design not only ensures the reliability and convenience of fixing the wire harness assembly, but also reduces production costs.

[0060] In this embodiment, the terminal 710 is used for connecting internal wiring of the battery pack 600. The size of the mounting slot 720 is adapted to the size of the connector.

[0061] In this embodiment, the socket structure 700 has multiple second mounting holes 730 arranged circumferentially. A third fastener (not shown in the figure) is detachably installed within each second mounting hole 730, and the socket structure 700 is detachably connected to the battery pack 600 via the third fastener. This design allows the socket structure 700 to be securely mounted on the battery pack 600 through multiple fixing points, avoiding displacement or loosening caused by single-point force, thereby improving the mechanical stability and structural reliability of the connection. Furthermore, the detachable third fastener connection method allows for quick disassembly and assembly without damaging the battery pack 600 body or other related components when the socket structure 700 needs to be replaced, repaired, or cleaned.

[0062] Preferably, the second mounting hole 730 is a threaded hole, and the side wall of the battery pack 600 has through holes that correspond one-to-one with the second mounting hole 730. The third fastener is a bolt, which passes through the through holes from the outside to the inside and is screwed into the second mounting hole 730 to fix the socket structure 700 to the battery pack 600.

[0063] In this embodiment, a sealing plate 800 is detachably provided on the socket structure 700. The sealing plate 800 is rectangular and can enclose the mounting groove 720. This design can prevent external dust from entering the socket structure 700 after the wiring harness assembly is disassembled.
