Description

Technical Field

[0001] This utility model relates to a wiring harness structure for an electric vehicle controller. Background Technology

[0002] To facilitate installation and maintenance, electric vehicle controllers typically have cables with a certain amount of slack.

[0003] Fixed cable management devices cannot effectively accommodate redundant cables of varying lengths, potentially leading to loose and sagging cables. This not only looks unsightly but also poses a risk of the cables getting caught in wheels or rubbing against other components. Furthermore, installation workers need to spend extra time and effort dealing with cables that are too long or too short. If the cable management device cannot be adjusted, non-standard bundling methods may be forced, affecting product reliability and safety.

[0004] Therefore, a wiring harness structure for an electric vehicle controller is proposed to address the above issues. Utility Model Content

[0005] The purpose of this utility model is to overcome the existing defects and provide an electric vehicle controller wiring structure that can solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an electric vehicle controller cable harness structure for harnessing the controller's cables, comprising a frame structure and a harnessing mechanism, wherein the harnessing mechanism is disposed inside the frame structure;

[0007] The frame structure includes a base plate, guide columns, a cover plate, and long bolts. The guide columns are fixed to the top surface of the base plate, the cover plate is sleeved on the guide columns, and the long bolts connect the cover plate to the base plate.

[0008] The cable winding mechanism includes a guide ring, a slide rail, a guide roller, a slider, a central gear, and an offset rack. The guide ring and the slide rail are fixed to the base plate of the frame structure. The guide roller is slidably connected to the slide rail via the slider. The offset rack is fixed to the side of the slider and meshes with the central gear, so that the two guide rollers can slide in opposite directions along the slide rail to adjust the distance between them for winding and winding the cable.

[0009] Preferably, the long bolt is also used to mount the entire structure onto the vehicle frame.

[0010] Preferably, the guide ring of the gathering mechanism is used to guide the cable through and around the two guide rollers in sequence.

[0011] Preferably, the guide ring is formed by welding multiple ring bodies vertically from bottom to top.

[0012] Preferably, it also includes auxiliary components, which include a slotted strip on the bottom surface of the cover plate and a rubber pad on the upper end of the guide roller. When the cover plate is locked, the slotted strip squeezes the rubber pad to increase friction and lock the position of the guide roller.

[0013] Preferably, the slots on the surface of the slotted strip are deformed and embedded in the rubber pad to achieve friction locking.

[0014] Preferably, the height of the guide roller is the same as the height of the guide ring, which is suitable for winding and bundling multiple cables.

[0015] Preferably, the meshing connection between the central gear and the offset rack allows one slider to slide along the slide rail while the other slider slides in the opposite direction, thus enabling real-time adjustment of the distance between the two guide rollers.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows: This electric vehicle controller wiring structure, through the meshing transmission mechanism of the central gear and the offset rack, enables the two guide rollers to slide synchronously in opposite directions, thereby steplessly adjusting the distance between them; this solves the problem of the fixed size of traditional wiring devices and their inability to adapt to redundant cables of different lengths, and can meet the cable length variation requirements caused by various vehicle models or installation positions, achieving the flexibility and versatility of "one structure, multiple applications".

[0024] 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.

[0025] like Figure 1-5 As shown, an electric vehicle controller cable harness structure is used to harness the controller cable 4. It includes a frame structure 1 and a harnessing mechanism 2, with the harnessing mechanism 2 located inside the frame structure 1.

[0026] The frame structure 1 includes a base plate 11, guide posts 12, cover plates 13 and long bolts 14. The guide posts 12 are fixed to the top surface of the base plate 11, the cover plates 13 are sleeved on the guide posts 12, and the long bolts 14 connect the cover plates 13 to the base plate 11. The long bolts 14 are also used to install the entire structure on the vehicle frame.

[0027] The cable winding mechanism 2 includes a guide ring 21, a slide rail 23, and a guide roller 24, which directly contact and wind up the cable 4. Its roller structure greatly reduces sliding friction with the cable 4, making adjustments by pulling the cable 4 smoother and protecting the cable 4's insulation layer from wear. It also includes a slider 22, a central gear 25, and an offset rack 26. The guide ring 21 and slide rail 23 are fixed to the base plate 11 of the frame structure 1. The guide roller 24 is slidably connected to the slide rail 23 via the slider 22. The offset rack 26 is fixed to the side of the slider 22 and meshes with the central gear 25, allowing the two guide rollers 24 to slide in opposite directions along the slide rail 23 to adjust the distance between them for winding and winding the cable 4. The meshing connection between the central gear 25 and the offset rack 26 allows one slider 22 to slide along the slide rail 23 while the other slider 22 slides in the opposite direction, achieving real-time adjustment of the distance between the two guide rollers 24.

[0028] Specifically, the guide ring 21 of the coiling mechanism 2 guides the cable 4 through and around two guide rollers 24 in sequence. The guide ring 21 is formed by welding multiple rings vertically from bottom to top, serving as the cable 4's entry point for initial guidance and positioning, preventing multiple cables 4 from tangling at the entry point. Its multi-layered structure allows multiple cables 4 to pass through in parallel without interference. The height of the guide rollers 24 is the same as the height of the guide ring 21, suitable for coiling multiple cables 4, achieving parallel management of multiple cables 4 in three-dimensional space. Each layer can independently guide one cable 4, which is then coiled by the guide roller 24 segment of the corresponding height, avoiding cross-interference between cables 4 in upper and lower layers, resulting in extremely neat and orderly wiring.

[0029] Specifically, it also includes auxiliary component 3, which includes a slotted strip 31 on the bottom surface of the cover plate 13 and a rubber pad 32 on the upper end of the guide roller 24. When the cover plate 13 is locked, the slotted strip 31 squeezes the rubber pad 32 to increase friction and lock the position of the guide roller 24. The slots on the surface of the slotted strip 31 and the rubber pad 32 deform and embed into each other to achieve friction locking. This mechanical interlocking effect of "deformation embedding" can reliably resist the continuous vibration during vehicle operation, prevent the slider 22 from shifting, and ensure the long-term stability of the convergence state.

[0030] This electric vehicle controller cable harness structure incorporates a harnessing mechanism 2 housed within a frame structure 1. The harnessing mechanism 2 harnesses the controller cable 4, while the frame structure 1 supports the harnessing mechanism 2 and securely mounts the entire structure onto the vehicle frame. A guide post 12 is fixed to the top surface of the base plate 11 in the frame structure 1. A cover plate 13 is connected to the guide post 12, and then the cover plate 13 is connected to the base plate 11 using long bolts 14. Simultaneously, the entire structure is mounted onto the vehicle frame using the long bolts 14. The guide ring 21 and slide rail 23 in the harnessing mechanism 2 are both fixed to the base plate 11. Therefore, the cable 4 is first passed through the guide ring 21, then sequentially around two guide rollers 24. The slider 22 at the end of the guide roller 24 is slidably connected to the slide rail 23, and an offset rack 26, meshing with a central gear 25, is fixed to the side of the slider 22. After one slider 22 slides along the slide rail 23, the other slider 22 slides along the slide rail 23 in the opposite direction. Therefore, the distance between the two guide rollers 24 can be adjusted in real time to meet the winding and bundling requirements of cables 4 of different lengths. Then, the cover plate 13 is put on along the guide post 12 and locked with the long bolt 14. An auxiliary part 3 is set between the cover plate 13 and the upper end of the guide roller 24. The slotted strip 31 on the bottom surface of the cover plate 13 presses the rubber pad 32 on the upper end of the guide roller 24. The rubber pad 32 deforms and embeds into the slot of the slotted strip 31, increasing the friction. Combined with the threaded locking force of the long bolt 14, it restricts the sliding of the guide roller 24 and ensures that it meets the bundling requirements of the cable 4. At the same time, the guide ring 21 is formed by welding multiple rings vertically from bottom to top. The height of the guide roller 24 is the same as the height of the guide ring 21, so it can be used for winding and bundling multiple cables 4.

[0031] Finally, it should be noted that the above are merely preferred embodiments of this utility model and are not intended to limit the utility model. Although the 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 this utility model should be included within the protection scope of this utility model.
