Description

Technical Field

[0001] This utility model relates to the field of wiring structure technology, specifically to an improved battery manager wiring structure. Background Technology

[0002] In battery management systems, the battery manager, as the core control unit, directly impacts the overall system's operational efficiency and safety through the reliability and ease of its wiring structure. However, existing battery manager wiring structures still suffer from the following significant drawbacks:

[0003] Insufficient connection stability: Traditional terminal blocks mostly adopt a simple plug-in design and lack an effective anti-loosening mechanism. During equipment operation, vibration or external impact can easily cause the wires to fall off, resulting in poor contact or even open circuit failure, which seriously threatens the stability of the battery management system.

[0004] Disorganized wiring management: The internal wires of the battery manager are densely arranged without standardized restraint and guidance devices, resulting in tangled wires and unclear markings. This not only increases the difficulty of maintenance but also may cause short circuit risks due to friction and damage to the wires.

[0005] Weak protection performance: The existing wiring structure has poor dust and water resistance. Especially under harsh working conditions, dust or liquid can seep into the electrode contacts, which can corrode them, accelerate the aging of the insulation layer, and shorten the service life of the equipment.

[0006] Poor heat dissipation efficiency: The battery manager draws a large current when it is working. The traditional wiring structure does not have a dedicated heat dissipation channel, and the heat accumulates in the confined space and is difficult to dissipate. Long-term high temperature environment will accelerate the performance degradation of electronic components.

[0007] Installation and maintenance are inconvenient: The wiring structure and the chassis are mostly fixed and integrated. When it is necessary to expand the battery pack or replace the parts, the entire wire needs to be disassembled, which is complicated and time-consuming and cannot meet the needs of rapid maintenance.

[0008] How to solve the problems existing in the above-mentioned prior art has become an urgent problem to be solved by those skilled in the art. Utility Model Content

[0009] To address the shortcomings of existing technologies, this utility model provides an improved battery manager wiring structure that can completely solve the problems existing in the prior art.

[0010] To achieve the aforementioned goals of good stability and ease of disassembly, this utility model provides the following technical solution:

[0011] An improved battery manager wiring structure includes a housing with a detachable cover on the top. The housing contains a wiring structure, including a battery compartment fixedly installed in the center. A first connector is fixedly mounted on the top of the battery compartment. A corresponding socket is provided on the cover, extending the first connector outside the socket. Second connectors are located on the front and rear side walls of the battery compartment. Cable bundles are arranged around the battery compartment, each including a base and a top cover. The base is detachably fixed to the bottom surface of the housing. Corresponding slots for clamping wires are provided on the opposing surfaces of the base and top cover. The base and top cover are rotatably connected on one side and connected on the other side by a snap-fit.

[0012] Furthermore, power sockets are fixedly installed on the left and right sides of the chassis, a display screen is fixedly installed on the top of the chassis cover, and two fans are fixedly installed on the front side of the chassis.

[0013] Furthermore, a dust cover is flipped onto the insertion hole on the top surface of the box lid.

[0014] Furthermore, the wire harness block is made of rubber.

[0015] Furthermore, an identification groove is provided on the top of the wire harness block along the through groove.

[0016] Furthermore, a permanent magnet connecting ring is provided circumferentially on the mating surface between the cover and the housing.

[0017] Furthermore, a polymer sealing ring is provided on the inner side of the permanent magnet connecting ring.

[0018] Furthermore, two wire harness blocks are respectively provided on the front, back, left, and right sides of the battery box.

[0019] Furthermore, the lid is made of a transparent material.

[0020] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0021] 1. The first wiring plug extends to the box cover socket: By extending the plug directly to the outside of the box cover and forming a through connection with the socket, the risk of plug loosening due to vibration is effectively reduced, ensuring the stability of high voltage and high current transmission.

[0022] 2. Partitioned fixing design of wire harness blocks: Rubber wire harness blocks arranged around the battery box clamp the wires through the through slots, and combined with the top marking slot, the wires are classified and managed to avoid wires crossing and confusion, and improve maintenance efficiency.

[0023] 3. The second wiring plug is located on the front and rear sides of the battery box: it provides multi-directional wiring interfaces to adapt to different battery pack layout requirements, supports quick expansion or replacement of battery modules, and does not require reorganizing all the wires.

[0024] 4. Two fans located on the front of the chassis directly provide air cooling to the internal wiring area, reducing the damage to the insulation layer caused by the current heat effect and extending the equipment life;

[0025] 5. Permanent magnet connecting ring + polymer sealing ring: The cover and the housing are magnetically attracted to achieve quick closure. It can be opened and closed quickly without tools, which facilitates real-time monitoring and fault diagnosis. The inner sealing ring further enhances the dustproof and waterproof performance and adapts to complex environments such as humidity and dust.

[0026] 6. Separate power sockets: The power sockets on the left and right sides of the chassis are set separately and isolated from the battery box wiring area to avoid the risk of accidental contact, while also facilitating the expansion of external devices;

[0027] 7. The rubber cable bundle is made of elastic material, which can not only firmly fix the wires, but also buffer the tensile stress on the wires caused by mechanical vibration, reducing the risk of fatigue breakage. The marking groove on the top of the cable bundle makes it easy to mark the purpose of the wires, and with the transparent cover, the internal wiring status can be clearly observed, reducing the probability of operation and maintenance personnel making mistakes.

The cover 4 is made of transparent material to allow observation of the internal wiring status, and a display screen 5 is integrated on the top surface of the cover 4 to display battery management parameters in real time. The fans 3 have a rated airflow of 5 CFM, noise level ≤30 dB, and meet IP54 dust and water resistance requirements.

[0036] The wiring structure includes a battery box 6, which is fixedly installed in the middle of the housing 1. A first wiring plug 7 is fixedly installed on the top of the battery box 6. A socket is provided on the cover 4 corresponding to the first wiring plug 7, and the first wiring plug 7 extends to the outside of the socket. This design allows the plug to be directly exposed outside the cover 4, reducing the risk of loosening due to vibration and ensuring the stability of high-voltage and high-current transmission. The front and rear side walls of the battery box 6 are provided with second wiring plugs 8, providing multi-directional wiring interfaces to adapt to different battery pack layout requirements and support rapid capacity expansion or replacement of battery modules without the need to reorganize all the wires. Two cable bundles 9 are provided on each of the four sides of the battery box 6, for a total of eight, evenly distributed around the battery box 6. Each cable bundle 9 includes a base 901 and a top cover 902. The base 901 is detachably fixed to the bottom surface of the housing 1. Corresponding slots 903 for clamping wires are provided on the opposite surfaces of the base 901 and the top cover 902. After the wire is placed in the slot, it is clamped and fixed by closing the top cover 902. The base 901 and the top cover 902 are hinged on one side by a rotating shaft and locked on the other side by a buckle 904.

[0037] In this embodiment, a dust cover 10 is flipped and connected to the socket on the top surface of the box cover 4. When not in use, it covers the socket of the first wiring plug 7 to prevent foreign objects from entering; when wiring is required, it can be flipped up and opened, making operation convenient.

[0038] In this embodiment, the wire harness block 9 is made of rubber, which has an elastic buffering effect and can absorb the tensile stress on the wires caused by mechanical vibration, reducing the risk of fatigue fracture.
