The battery pack is usually composed of multiple cells connected in series and parallel. Its casing is made of aluminum alloy or high-strength steel, which has high strength, high rigidity and good waterproof and dustproof performance, and can effectively protect the internal components.

[0003] However, after a collision with the underside of a vehicle or prolonged use, the battery pack needs to be inspected to determine the condition and lifespan of the internal cells. Currently, in battery pack diagnostics, the diagnostic harness is mostly connected to the battery pack via a plug-in connection. This connection method is prone to causing the diagnostic harness to detach during vehicle operation or when subjected to external impacts, leading to equipment interruption and affecting the normal progress of diagnostic work. Therefore, there is an urgent need for a battery pack diagnostic harness anti-detachment device to solve the above problems and ensure the stability and reliability of the diagnostic process.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] This utility model discloses a battery pack diagnostic harness anti-detachment device, which aims to effectively prevent the diagnostic harness from falling off the battery pack housing 1, ensure the stable transmission of diagnostic data and the normal operation of the equipment, and at the same time provide comprehensive protection for the harness, reducing harness damage caused by external force or long-term bending.

[0027] The battery pack housing 1, as a core component, has a wiring harness interface 11 at its output end, used to connect the diagnostic wiring harness during cell testing. Limiting plates 12 are fixedly installed on the side walls of the battery pack housing 1 on both sides of the wiring harness interface 11, and these limiting plates 12 are slidably connected to positioning plates 16. The side wall of the positioning plate 16 is rotatably connected to one end of a support rod 14, while the other end of the support rod 14 is rotatably connected to a clamping plate 13. The two ends of a first spring rod 15 are hinged to the middle of the limiting plate 12 and the middle of the support rod 14, respectively. This connection method allows the first spring rod 15 to not only provide continuous clamping force to the clamping plate 13, but also to allow for partial separation of the clamping plate 13 when needed, facilitating the installation and removal of the wiring harness.

[0028] A pair of clamping plates 13, each semi-circular, are arranged on one side of the wire harness interface 11. Under the combined action of the elastic force of the first spring rod 15 and the support of the support rod 14, they approach each other, adhering to the wire harness and applying pressure to it, thereby restricting the position of the wire harness and preventing the diagnostic connector from being pulled out. The restrictive effect of the support rod 14 and the first spring rod 15, in conjunction with the clamping plates 13, restricts the diagnostic connector, reducing the risk of the wire harness detaching under external force, which could lead to loss of diagnostic data. Simultaneously, the clamping plates 13 protect the connection point between the wire harness and the diagnostic connector, reducing the occurrence of bending and breakage.

[0029] To facilitate the removal of the diagnostic harness, a pressing post 22 is slidably connected to the side wall of the battery pack housing 1 above the harness interface 11. The pressing post 22 is connected to the side wall of the battery pack housing 1 via multiple sets of second-generation spring rods 23. The side wall of the battery pack housing 1 is rotatably connected to a limiting shaft 21 outside the positioning plate 16. One end of the traction belt 2 is fixed to the side wall of the second-generation spring rod 23. The other end of the traction belt 2 passes through the battery pack housing 1, bypasses the limiting shaft 21, and contacts the middle of the support rod 14. When it is necessary to remove the diagnostic harness, the operator simply presses the pressing post 22 to displace it and pulls the traction belt 2. The pulling action of the traction belt 2 causes the support rod 14 to move to both sides, thereby disengaging the clamping plate 13 from the harness, releasing the restriction on the diagnostic harness, and allowing the operator to easily remove the diagnostic harness.

[0030] A rubber plate 3 is installed on the inner wall of the clamping plate 13, and the rubber plate 3 is connected to the clamping plate 13 by multiple sets of No. 3 spring rods 31. A guide plate 32, which is inclined, is also connected between one side of the No. 3 spring rod 31 and the end of the clamping plate 13. When the diagnostic wiring harness is connected, the guide plate 32 uses its inclined surface to guide the connector smoothly into the space between the pair of clamping plates 13. Supported by the elastic force of the No. 3 spring rods 31, the rubber plate 3 can make close contact with diagnostic wiring harnesses of different specifications, increasing friction and ensuring the stability of the wiring harness connection. It also adapts to different specifications of wiring harnesses, improving the versatility of the device.

[0031] The side wall of the clamping plate 13 also has a first sliding groove 4, through which a first extension plate 41 is slidably connected. A second extension plate 42 is slidably connected to one side of the first extension plate 41. After the wiring harness connection is completed, the operator can pull the second extension plate 42 to displace it, thereby causing the first extension plate 41 and the second extension plate 42 to extend, providing additional protection to the end of the wiring harness. This extension structure design effectively protects the wiring harness from the risk of insulation damage and breakage caused by prolonged bending.

[0032] To enhance the fixing effect of the clamping plates 13, a first magnet 5 and a second magnet 51 are fixed to the upper and lower ends of the opposite sidewalls of the pair of clamping plates 13, respectively, and their magnetic forces attract each other. When the clamping plates 13 restrict the diagnostic wire harness, the attraction between the magnets and the elastic force of the first spring rod 15 work together to further enhance the fixing ability of the clamping plates 13 on the wire harness.

[0033] In addition, the side wall of the clamping plate 13 is also provided with a second sliding groove 6, which is also set at an angle. During the process of the operator connecting the diagnostic harness to the harness interface 11, the second sliding groove 6 uses its angle to guide the installation of the diagnostic harness, working in conjunction with the guide plate 32 to ensure the smooth connection process.

[0034] This utility model's battery pack diagnostic harness anti-detachment device achieves reliable fixation and effective protection of the diagnostic harness through the ingenious design and synergistic action of its components. During normal use, the first spring rod 15, support rod 14, and clamping plate 13 work together to apply appropriate clamping force to the harness, preventing it from detaching and protecting it from bending damage. When the harness needs to be removed, components such as the pressing column 22, traction belt 2, and second spring rod 23 respond quickly, causing the clamping plate 13 to separate, facilitating the removal of the harness. The combined design of the rubber plate 3, third spring rod 31, and guide plate 32 not only improves adaptability to different harness specifications but also enhances the stability of the harness connection. The extension protection function of the first extension plate 41 and the second extension plate 42 further reduces the risk of damage to the harness during use. The magnetic attraction provides additional protection for the fixation of the clamping plate 13. The entire device is compact and easy to operate, effectively extending the service life of the harness and reducing equipment maintenance costs while ensuring smooth diagnostic work.

[0035] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
