Description

Technical Field

[0001] This utility model relates to the field of testing platform technology, and in particular to a testing platform for low-voltage wiring harnesses of electric vehicles equipped with intelligent monitoring devices. Background Technology

[0002] Low-voltage wiring harnesses in electric vehicles are the "nerve vessels" of the vehicle's low-voltage system (such as 12V / 24V circuits, responsible for power supply and signal transmission for devices like lights, steering, wipers, and in-vehicle entertainment systems). Their performance directly affects the vehicle's safety, reliability, and functionality. A low-voltage wiring harness testing platform is a comprehensive testing device specifically designed to verify the compliance of wiring harness design, the stability of manufacturing processes, and long-term durability. Its core objective is to detect problems such as abnormal conductivity, insulation failure, and insufficient mechanical strength in the wiring harness in advance, preventing malfunctions during vehicle operation.

[0003] A wire harness voltage testing platform, authorized under publication number CN222719626U, includes a machine base. The top surface of the machine base has vertical holes, and a support frame is bolted to the inner side of the machine base. An adjustable slide block is slidably installed inside the frame. When testing the voltage of a wire harness using the platform, the two ends of the wire harness can be spread out, allowing each wire in the harness to be easily inserted into the corresponding hole in the multi-hole frame on the top side of the base. Then, rotating the rotating rod at the top of the multi-hole frame causes the rotating rod to screw into the multi-hole frame and push a pressure block, allowing the pressure block to move and press and limit the wires. Each group of wires can be inserted into one hole in the multi-hole frame and limited, facilitating the limitation of both ends of the wire harness. Then, the operator can use the appropriate equipment to test the voltage of the wire harness.

[0004] Regarding the aforementioned technologies, the existing wiring harness testing platforms have the following drawbacks: long-term storage of wiring harnesses exposes the terminals to air for extended periods, leading to oxidation of the terminals, the formation of an oxide layer on the surface, increased contact resistance, and reduced testing accuracy. Therefore, this invention provides a low-voltage wiring harness testing platform for electric vehicles equipped with intelligent monitoring devices. Utility Model Content

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.

[0022] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," "sleeved / connected," "connected," etc., should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0023] Example 1: Reference Figure 1-4The electric vehicle low-voltage wiring harness testing platform, equipped with intelligent monitoring devices, includes a support platform 1. This platform supports the entire platform, providing a stable foundation to ensure that each component remains in a fixed position during operation, preventing vibration from affecting testing accuracy. A hydraulic cylinder 14 is fixedly connected to the outer side of the support platform 1, driving a rotating plate 11 to rise and fall vertically. This adjusts the distance between the rotating plate 11 and the components above it and the wiring harness to be tested, adapting to the testing requirements of different wiring harness specifications. The output end of the hydraulic cylinder 14 is fixedly connected to the rotating plate 11, used to install cleaning components and short-term oxidation inhibition components. These components can be adjusted in position with the hydraulic cylinder 14, while also providing a mounting carrier for the components to ensure stable operation. To ensure stability, a cleaning component is provided on the outer side of the rotating plate 11 to remove dust, impurities, and other contaminants from the surface of the wire harness to be tested, preventing contaminants from affecting the accuracy of subsequent test results. The cleaning component includes a first motor 12 fixedly connected to the outer side of the rotating plate 11, providing power to the cleaning component and driving the first rotating block 19 and the elastic fiber brush 20 to rotate, thus achieving a cleaning action on the wire harness to be tested. The output end of the first motor 12 passes through the rotating plate 11, and the output end of the first motor 12 is fixedly connected to the first rotating block 19, which is used to install a disc spring 4 to transmit the power of the first motor 12 to the elastic fiber brush 20, causing the elastic fiber brush 20 to rotate synchronously. Multiple disc springs 4 are fixedly connected to the outer side of the rotating plate 19, providing elastic cushioning. This allows the elastic fiber brush 20 to closely adhere to the wire harness surface during cleaning, while preventing damage to the wire harness sheath due to excessive pressure. The end of the disc spring 4 furthest from the first rotating block 19 is fixedly connected to the elastic fiber brush 20, which, through rotation, contacts the wire harness surface to physically remove contaminants. The elastic material can adapt to the irregular shape of the wire harness. A short-term oxidation suppression component is provided on the outer side of the rotating plate 11. This component treats the surface of the wire harness after cleaning, forming a temporary protective layer to suppress short-term oxidation and ensure stable wire harness performance during testing. The device includes a second motor 13 fixedly connected to the outside of the rotating plate 11, which provides power to suppress short-term oxidation components and drives the second rotating block 21 and the slightly damp cleaning cotton 22 to rotate, thereby achieving protective treatment for the wire harness that can be detected. The output end of the second motor 13 passes through the rotating plate 11, and the output end of the second motor 13 is fixedly connected to the second rotating block 21 for mounting the slightly damp cleaning cotton 22. The power of the second motor 13 is transmitted to the slightly damp cleaning cotton 22, causing the slightly damp cleaning cotton 22 to rotate synchronously. The slightly damp cleaning cotton 22 is fixedly connected to the outside of the second rotating block 21. After absorbing the protective liquid, the protective liquid is evenly applied to the surface of the wire harness to be tested by rotation, forming a temporary protective layer to suppress oxidation.A liquid storage tank 15 is fixedly connected to the outside of the support platform 1 to store a protective liquid that inhibits wire harness oxidation and provides liquid replenishment for components that inhibit short-term oxidation. An outlet pipe 18 is fixedly connected to the output end of the liquid storage tank 15 to transport the protective liquid from the tank to the slightly damp cleaning cotton 22. A pressure pump is installed at the connection point between the outlet pipe 18 and the liquid storage tank 15 to provide power and control the delivery pressure and flow rate of the protective liquid, ensuring that the protective liquid is stably and quantitatively delivered to the slightly damp cleaning cotton 22, avoiding excessive or insufficient liquid from affecting the protective effect. The outlet pipe 18 faces the slightly damp cleaning cotton 22 to ensure that the delivered protective liquid accurately acts on the slightly damp cleaning cotton 22. Cleaning cotton 22 is used to maintain a suitable humidity level for the slightly damp cleaning cotton 22. A mounting bracket 16 is fixedly connected to the outer side of the support platform 1 for mounting the electric push rod 17, providing fixed support for the electric push rod 17 and ensuring its stable position during operation. The electric push rod 17 is fixedly connected to the outer side of the mounting bracket 16, which can drive the miniature resistance detection probe 5 to move horizontally, adjusting the distance between the probe and the wire harness to achieve precise contact or separation between the probe and the wire harness. The output end of the electric push rod 17 is fixedly connected to the miniature resistance detection probe 5, used to contact the wire harness to detect its resistance value, obtain the wire harness conductivity data, and determine whether the wire harness has a fault.

[0024] Example 2: Reference Figure 1-4 Based on the same concept as in Embodiment 1 above, this embodiment further proposes that the support platform 1 serves as a basic load-bearing structure to support the overall device and provide a stable installation reference. A groove 2 is provided on the outer side of the support platform 1, providing guidance and limiting space for the movement of the slider 6, ensuring its movement along a fixed trajectory. A threaded rod 23 is rotatably connected to the inner wall of the groove 2, and the threaded rod 23, by rotation, drives the threadedly connected slider 6 to move linearly. A motor 3 is fixedly connected to the outside of the support platform 1. The motor 3 provides power for the rotation of the threaded rod 23. The output end of the motor 3 passes through the support platform 1 and is fixedly connected to the threaded rod 23 to achieve direct power transmission. A slider 6 is threadedly connected to the outside of the threaded rod 23. The slider 6 can drive the sliding frame 7 to move synchronously under the drive of the threaded rod 23. The sliding frame 7 is fixedly connected to the outside of the slider 6. The sliding frame 7 is used to install the fixed frame 9 and drive it to move as a whole. The fixed frames 9 are fixedly connected to both ends of the sliding frame 7. The fixed frames 9 provide a stable mounting carrier for the cylinder 8. A cylinder 8 is fixedly connected to the outside of the fixed frame 9. The cylinder 8 can drive the clamping block 10 to open and close through telescopic movement. The output end of the cylinder 8 is fixedly connected to the clamping block 10. The clamping block 10 is used to clamp and fix the target object to complete the corresponding operation task.

[0025] The working principle of this utility model is as follows: Multiple cylinders 8 and clamping blocks 10 are used to clamp and fix the wire harness. The motor 3 drives the threaded rod 23 to rotate, which in turn drives the sliding frame 7 and the wire harness via the slider 6, aligning the wire harness terminals with the elastic fiber brush 20. The hydraulic cylinder 14 drives the rotating plate 11 to move, allowing the elastic fiber brush 20 to extend into the wire harness terminals. The first motor 12 drives the elastic fiber brush 20 to rotate, cleaning the wire harness terminals. After cleaning, the hydraulic cylinder 14 resets, and the motor 3 continues to rotate, aligning the wire harness terminals with the slightly damp cleaning cotton 22. The second motor 13 then drives the slightly damp cleaning cotton 22... The cleaning cotton 22 rotates to further clean the terminals of the wire harness, wiping away residual oxide debris from the fiber brush and forming a very thin protective film on the terminal surface. The pressure pump controls the outlet pipe 18 to deliver neutral cleaning solution and drip it onto the slightly damp cleaning cotton 22 to replenish the neutral cleaning solution. Through the setting of the electric push rod 17 and the miniature resistance detection probe 5, it makes precise contact with the metal contact surface of the terminal and quickly detects the contact resistance. If the resistance value is lower than the qualified threshold, the device automatically transfers the wire harness to the next detection station; if the resistance value is higher than the qualified threshold, the fixture automatically triggers "secondary cleaning" (repeated cleaning process).

[0026] 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.
