Description

Technical Field

[0001] This utility model relates to the field of wire harness guiding technology, and in particular to a glass lifting wire harness guiding device and vehicle. Background Technology

[0002] In recent years, the automotive industry has developed rapidly, and passengers' demands for privacy and comfort have been increasing. As a result, window dimming functions have emerged, typically achieved through window regulators. Cables and other wiring harnesses are essential structures for driving these regulators, and how to properly manage these wiring harnesses within the automotive interior is a problem that urgently needs to be solved.

[0003] In related technologies, the wiring harness of a typical smart window regulator is connected to a glass wiring harness connector at one end and a power source at the other. The wiring harness is spirally wound in the same direction around a constraint rod. A slider, fixedly connected to a glass bracket, is slidably mounted on the constraint rod. When the glass is raised or lowered, the wiring harness extends or retracts along the constraint rod with the glass bracket, driven by the slider, ensuring that the wiring harness rises and falls synchronously with the glass. However, because the glass bracket is fixedly connected to the slider, the constraint rod often needs to be longer than the window regulator's lifting track to ensure sufficient space for the compressed wiring harness when the glass is at its lowest position. This occupies a significant amount of space, making its arrangement difficult in the confined space inside a car door. Furthermore, since the window regulator's lifting track is generally a zigzag or curved line, maintaining consistency along the track to ensure synchronous movement of the wiring harness with the glass bracket further increases the manufacturing difficulty and cost of the constraint rod. Utility Model Content

[0004] The purpose of this utility model is to provide a glass lifting wire harness guide device and a vehicle, which has a simple structure, occupies little space, and has low manufacturing cost.

[0005] To achieve this objective, the present invention adopts the following technical solution:

[0025] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0026] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between 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.

[0027] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0028] In the description of this embodiment, the terms "upper," "lower," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0029] On the one hand, please refer to Figures 1 to 4This embodiment provides a glass lifting wire harness guiding device, including: a wire harness 1, a guide 2, a slider 3, and a transmission assembly. One end of the wire harness 1 is used to connect to a glass wire harness connector 5, and the other end of the wire harness 1 is used to connect to a power source. The guide 2 extends along the glass lifting direction. One end of the wire harness 1 connected to the glass wire harness connector 5 is fixedly connected to the slider 3. One end of the transmission assembly is rotatably connected to the slider 3, and the other end of the transmission assembly is rotatably connected to a glass bracket 11. At least a portion of the wire harness 1 is spirally and movably arranged on the guide 2. The slider 3 is slidably connected to the guide 2, so that the slider 3 drives the wire harness 1 to extend or retract. With this configuration, the glass lifting wire harness guiding device, through the transmission assembly connected to the slider 3 and the glass bracket 11, transforms the large stroke sliding of the glass bracket 11 into the small stroke sliding of the slider 3. Since the extension of the wire harness 1 depends on the displacement of the slider 3, the length required for the slider 3 to slide is reduced, and the corresponding length of the guide 2 is reduced, providing storage space for the retracted wire harness 1. This glass lifting wire harness guiding device, with its simple structure, reduces the space occupied, facilitates arrangement, and lowers manufacturing costs. Specifically, harness 1 is a spiral-shaped, freely stretchable cable.

[0030] Alternatively, please refer to Figure 1 and Figure 2 The transmission assembly includes a first connecting rod 9 and a second connecting rod 10. One end of the first connecting rod 9 is rotatably connected to the slider 3, and the other end of the first connecting rod 9 is rotatably connected to the second connecting rod 10. The end of the second connecting rod 10 away from the first connecting rod 9 is rotatably connected to the glass bracket 11. Through the design of the two-stage tandem connecting rod, the large stroke of the glass bracket 11 can be further compressed into the small stroke of the slider 3, enabling precise winding and unwinding of the wire harness 1 even when the length of the guide member 2 is less than the lifting rail of the glass lifter. This reduces the space occupied by the guide member 2 in the length direction, resulting in a compact layout. Simultaneously, the transmission assembly allows for an adjustable distance between the slider 3 and the glass bracket 11, eliminating the need for the guide member 2 to be parallel to the lifting rail of the glass lifter, thus facilitating the manufacturing and assembly of the guide member 2.

[0031] Optionally, the transmission assembly also includes a first rotating shaft 6, a second rotating shaft 7, and a third rotating shaft 8. The connection between the first connecting rod 9 and the slider 3 rotates around the first rotating shaft 6, the connection between the first connecting rod 9 and the second connecting rod 10 rotates around the second rotating shaft 7, and the connection between the second connecting rod 10 and the glass bracket 11 can rotate around the third rotating shaft 8. The arrangement of the first rotating shaft 6, the second rotating shaft 7, and the third rotating shaft 8 allows the glass bracket 11, the first connecting rod 9, the second connecting rod 10, and the slider 3 to be sequentially hinged, resulting in a longer service life, a smoother force transmission path, and faster assembly.

[0032] Please refer to Figure 3 and Figure 4In this embodiment, the guide member 2 has a C-shaped groove, and the wire harness 1 is housed in the C-shaped groove. With this configuration, the slider 3 can slide in the C-shaped groove, which plays a certain role in limiting and guiding, while the wire harness 1 is spirally coiled in the groove, which protects the wire harness 1 and prevents it from being damaged by friction with other components.

[0033] Further, please refer to Figure 3 The slider 3 includes a sliding part 31 and a fixing part 32. The sliding part 31 is slidably connected to the opening of the C-shaped groove, and the fixing part 32 is fixedly connected to one end of the glass wire harness connector 5 of the wire harness 1. With this configuration, the slider 3 slides relative to the C-shaped groove and is fixedly connected to the wire harness 1. When the wire harness 1 is stretched, the wire harness 1 is confined to the center of the C-shaped groove by the fixing part 32 of the slider 3, and will not contact the groove wall of the C-shaped groove, thus avoiding friction between the wire harness 1 and the groove wall and protecting the wire harness 1.

[0034] Specifically, the sliding part 31 is arranged in an "I" shape and has a top plate and a bottom plate arranged in parallel intervals, as well as a connecting plate connecting the top plate and the bottom plate. The top plate is located outside the C-shaped groove, the bottom plate is located inside the C-shaped groove, and the connecting plate passes through the opening of the C-shaped groove. With this arrangement, the sliding part 31 is embedded in the opening of the C-shaped groove, resulting in a compact overall structure and small space occupation.

[0035] Specifically, the fixing part 32 is a snap-fit ​​groove, which is fixedly connected to the connecting plate. One end of the wire harness 1 connecting to the glass wire harness connector 5 is snapped into the snap-fit ​​groove. This arrangement ensures that the slider 3 and the wire harness 1 are stably fixed, while the snap-fit ​​groove facilitates the assembly of the slider 3 and the wire harness 1. In other embodiments, the fixing part 32 can also be a cable tie, clamp, etc.

[0036] Further, please refer to Figure 3 The slider 3 also includes a limiting part 33, which is fixedly connected to the base plate and slidably disposed in the C-shaped groove. The limiting part 33 abuts against one end of the wire harness 1 connecting to the glass wire harness connector 5. Specifically, the limiting part 33 is a limiting stop or a limiting piece. The limiting part 33 extends from the base plate of the slider 3 into the C-shaped groove and abuts against the end of the wire harness 1 to form an end face stop. When the glass stops suddenly or the wire harness 1 spirals back, the impact force is borne by the limiting part 33, preventing the glass wire harness connector 5 from being pulled and causing the wire harness 1 to break. At the same time, the limiting part 33 slides in the groove. When the dimming glass descends, the limiting part 33 can push the wire harness 1 to retract and reset, ensuring the synchronous movement of the wire harness 1 and the glass bracket 11.

[0037] Preferably, the sliding part 31, the fixing part 32, and the limiting part 33 are integrally formed. This configuration results in a simple structure for the overall glass lifting harness guide device, which is easy to assemble.

[0038] In other embodiments, the guide 2 can also be a guide shaft, with the wire harness 1 spirally wound on the guide shaft, and the guide shaft slidingly engaging with the slider 3.

[0039] On the other hand, a vehicle is provided, which includes glass, glass bracket 11, door 4 and the aforementioned glass lifting harness guide device, wherein the glass is fixedly connected to the glass bracket 11, the glass bracket 11 is slidably connected to the door 4, and the guide member 2 of the glass lifting harness guide device is fixedly connected to the door 4.

[0040] Preferably, the guide member 2 is integrally formed with the door 4, resulting in a stable and reliable overall structure. In other embodiments, the guide member 2 can also be screwed to the door 4 using fasteners such as bolts and screws.

[0041] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
