Description

Technical Field

[0001] This invention relates to the field of automotive lighting wiring harness clamping technology, and particularly to a wiring harness clamping mechanism for automotive lighting wiring harnesses. Background Technology

[0002] The automotive lighting assembly typically involves multiple wiring harnesses, including high beam, low beam, turn signal, and daytime running light harnesses. As automotive lighting functions become increasingly complex, the number of internal wiring harnesses further increases, wiring space becomes increasingly limited, and the routing of wiring harnesses becomes increasingly diverse.

[0003] Currently, the following method is commonly used to fix vehicle headlight wiring harnesses: the wiring harness is first protected by a sheath such as a corrugated pipe or PVC pipe, then the sheathed wiring harness is tied and fixed to the cable tie holder or clip with cable ties, and finally the cable tie holder or clip is engaged with the mounting holes on the vehicle body sheet metal to achieve the positioning and fixation of the wiring harness inside the headlight.

[0004] However, the following problems exist in the current process of fixing vehicle headlight wiring harnesses: once the cable tie is tightened and locked, the bending shape of the wiring harness at the fixing point is fixed. Different specifications and materials of wiring harnesses have different bending stiffness. If the bending radius of a softer wiring harness is too small at the bend, it is easy to break and damage the internal wires. A stiffer wiring harness will generate a large rebound force and stress concentration at the bend. Over long-term use, the cable tie is easy to loosen or the terminal is pulled out of the connector. Existing cable ties fix all wiring harnesses in a one-size-fits-all manner and cannot adjust the bending curvature according to the hardness of the wiring harness to provide suitable support.

[0005] Therefore, the existing cable ties have a fixed bending curvature after locking, and the bending curvature cannot be adjusted according to the different hardness of the wire harness, which leads to damage to the wire harness or failure of fixation. This is a technical problem that needs to be solved by those skilled in the art. Summary of the Invention

[0006] In view of the above problems, the present invention provides a wiring harness clamping mechanism for vehicle headlights to solve the aforementioned technical problems.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a cable management clamping mechanism for vehicle headlight wiring harnesses, including a buckle, wherein a base is fixedly installed on the buckle, and a cable management assembly is provided on the base.

[0008] As a preferred embodiment, the cable management assembly includes a bending portion and a fixing portion.

[0009] As a preferred embodiment, the bending section includes two sets of bases respectively disposed on the left and right sides of the base. Each set of bases is composed of multiple bases connected in series by hinges along the length direction. Each base can rotate relative to the hinge point, so that the bending section can bend into the target arc according to the direction of the wire harness. Each base is provided with two limiting blocks, and a clamping space for accommodating the wire harness is formed between the two opposing limiting blocks.

[0010] As a preferred embodiment, the fixing part includes a lock head and a strap. The lock head is rotatably mounted on the base, and a lock head is rotatably mounted on a limiting block on the same side of the base. A strap is mounted on a limiting block on the other side. After the strap crosses over the wire harness, it locks and engages with the lock head to press and fix the wire harness in the clamping space.

[0011] As a preferred embodiment, the two ends of the base are respectively provided with mutually cooperating extended connection parts, and multiple bases are detachably connected in series through the extended connection parts.

[0012] As a preferred embodiment, pin holes are provided on both the left and right sides of the base. A pin is fixedly installed on the side of the base near the base, and a pin hole is provided on the other side of the base. The pin of the base passes through the pin hole on the base, so that the base is rotatably installed on the base. Adjacent bases are connected by hinged connection through the pin of one base passing through the pin hole of the other base.

[0013] As a preferred embodiment, the extended connection portion includes a plug slot disposed at one end of the base and a plug block disposed at the other end of the base, wherein the plug block is plugged into the plug slot of the other base.

[0014] As a preferred embodiment, a connecting plate is fixedly installed on the pin shaft, and a limit post is fixedly installed on the connecting plate. The limit post is used to limit the relative rotation angle between adjacent bases.

[0015] As a preferred embodiment, the opposing surfaces of the two limiting blocks on the same base and the inner wall of the limiting groove opened at the upper end of the base are all provided with a rubber layer.

[0016] As a preferred embodiment, the cross-section of the insertion slot and the insertion block is T-shaped.

[0017] As a preferred embodiment, the lower end of the base is provided with an injection groove.

[0018] The above-mentioned one or more technical solutions in the embodiments of the present invention have at least one of the following technical effects: First, the present invention solves the problem that the bending curvature is fixed after the existing cable ties are locked and cannot provide adaptive support for cable ties of different hardness by setting a bending part composed of multiple bases connected in series along the length direction, so that the bending part can bend into the target arc according to the direction of the cable ties. Second, by setting a fixing part composed of a lock head and a strap body, the cable ties are pressed and fixed in the clamping space by using the strap body to cross over the cable ties and lock the lock head, thus preventing the cable ties from moving around in the vehicle vibration environment. Third, by setting an expansion connection part that can cooperate with each other at both ends of the base, the detachable series combination of multiple cable clamping mechanisms is realized.

[0019] Second, this invention allows the wire harness to be bent into different arcs by rotating each base. When the wire harness is soft, it is supported by a large arc to avoid it from breaking. When the wire harness is hard, it is supported by a smaller arc to avoid stress concentration and excessive rebound force. In other words, a single mechanism can provide appropriate bending support for wire harnesses of different hardnesses through simple adjustment, solving the problems of soft wires breaking, hard wires loosening, or terminals being pulled off caused by the existing cable ties that fix all wire harnesses in a one-size-fits-all manner.

[0020] Third, this invention connects multiple bases in series by extending the connecting part, and adds independent bending parts in long-span bending sections as needed, so that the wire harness can be continuously supported in both the length direction and the bending direction. The operator can also increase or decrease the number of mechanisms at any time according to actual needs, and flexibly adapt to the wire harness layout requirements of different vehicle models.

[0029] To make the above-mentioned objects, features, and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of the present invention. However, the present invention can be practiced in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0030] like Figure 1 and Figure 2 As shown, a cable management clamping mechanism for a vehicle headlight wiring harness includes a buckle 1; the buckle 1 is fixedly mounted on a base 2, and a cable management assembly is provided on the base 2.

[0031] like Figure 1 As shown, the cable management assembly includes a bending part 3 and a fixing part 4.

[0032] like Figure 1 , Figure 3 , Figure 4 and Figure 5 As shown, the bending part 3 includes two sets of bases 30 respectively disposed on the left and right sides of the base 2. Each set of bases 30 is formed by multiple bases 30 connected in series along the length direction by hinges. Each base 30 can rotate relative to the hinge point, so that the bending part 3 can bend into the target arc according to the direction of the wire harness. Each base 30 is provided with two limiting blocks 31, and a clamping space for accommodating the wire harness is formed between the two opposing limiting blocks 31.

[0033] like Figure 1 , Figure 3 and Figure 4 As shown, the fixing part 4 includes a locking head 40 and a strap 41. The locking head 40 is rotatably mounted on the base 2. The locking head 40 is rotatably mounted on the limiting block 31 on the same side of the base 2. The strap 41 is mounted on the limiting block 31 on the other side. After the strap 41 passes over the wire harness, it locks and engages with the locking head 40 to press and fix the wire harness in the clamping space.

[0034] like Figure 1 and Figure 4 As shown, each end of the base 2 is provided with an expansion connection part 5 that can cooperate with each other, and multiple bases 2 are detachably connected in series through the expansion connection parts 5.

[0035] like Figure 1 , Figure 3 and Figure 4As shown, rubber layers 8 are provided on the opposing surfaces of the two limiting blocks 31 on the same base 30 and on the inner wall of the limiting groove opened at the upper end of the base 2. When the wire harness is pressed and fixed in the clamping space by the belt body 41, the outer surface of the wire harness is in contact with the rubber layer 8 on the opposing surface of the limiting block 31, and at the same time, the lower surface of the wire harness is in contact with the rubber layer 8 on the inner wall of the limiting groove at the upper end of the base 2. The rubber layer 8 forms an elastic wrap around the wire harness, which on the one hand increases the contact area and makes the pressing force evenly distributed, avoiding excessive local pressure that may cause indentations or damage to the wire harness sheath; on the other hand, the elastic deformation of the rubber layer 8 itself fills the gap between the wire harness and the rigid structure, increases the frictional resistance, and effectively prevents the wire harness from moving axially along the clamping space.

[0036] like Figure 2 As shown, the lower end of the base 30 is provided with an injection groove 300.

[0037] like Figures 1 to 5 As shown, in specific operations, the number of cable management clamping mechanisms is first determined based on the number of internal wiring harnesses in the headlight. When there is only one internal wiring harness, the operator takes a single cable management clamping mechanism and inserts it into the corresponding mounting hole on the headlight housing through the buckle 1 at the lower end of the base 2. When there are multiple internal wiring harnesses, the operator takes multiple bases 2 and connects adjacent bases 2 to each other through the expansion connection part 5. All bases 2 are connected in series along the length direction to form a continuous cable management channel matching the number of wiring harnesses. The lower end of the base 2 at the first end is provided with a buckle 1, which is fixed by engaging with the mounting hole on the headlight housing. The lower ends of the remaining extended series bases 2 are not provided with buckles 1, and are fixed by directly applying glue to the sheet metal. After this combination, the entire cable management channel is fixed by the buckle 1 at the first end and the glue bonding of the remaining bases 2, ensuring that the overall structure remains stable under vehicle vibration.

[0038] When the span of the bending section of the wire harness is large, a complete mechanism consisting of a base 2, a fixing part 4, and a bending part 3 is set at each end of the bending section. Multiple independent bending parts 3 are spaced apart on the bending section of the wire harness between the two complete mechanisms. Each independent bending part 3 does not have a base 2; it is formed by multiple bases 30 hinged together and connected in series, and includes a fixing part 4. Each base 30 is glued to the sheet metal by injecting glue through an injection channel 300 at its lower end (e.g., ...). Figure 5As shown), the operator first places the complete bending mechanism at both ends of the wire harness at predetermined positions on the sheet metal according to the general direction of the wire harness. Simultaneously, multiple independent bending sections 3 are placed at intervals along the bending segment on the sheet metal, ensuring all bending sections 3 are below the wire harness routing path. Then, the wire harness is passed sequentially from one end to the other through the clamping spaces of each bending section 3, placing the wire harness within the clamping space between the two limiting blocks 31 on each base 30. At this point, all bending sections 3 are in an unfixed state, and each base 30 can move and rotate freely on the sheet metal surface. The operator first... The complete mechanism at both ends of the wire harness is precisely positioned. Based on the actual bending arc of the wire harness, the bending portions 3 at both ends are bent to the target arc, so that the bending portions 3 at both ends form an arc track that matches the direction of the wire harness. Then, the complete mechanism at both ends is fixed to the sheet metal, so that the bending angle at both ends of the wire harness is initially fixed. Then, the operator adjusts the position and angle of each independent bending portion 3 along the bending section in sequence, so that each independent bending portion 3 is bent to an angle consistent with the arc of the bending portions 3 at both ends, and under the support of the wire harness, each independent bending portion 3 together forms an arc track that continuously supports the bending section of the wire harness.

[0039] During the adjustment process, the wire harness is always constrained within the clamping space of each bending section 3. The operator can fine-tune the position of each independent bending section 3 according to the actual fit of the wire harness to ensure that the wire harness is completely fitted with the arc track of each bending section 3. After the position and curvature of each independent bending section 3 are adjusted to the correct position, the operator injects glue into the contact surface between each base 30 and the sheet metal through the glue injection channel 300. After the glue cures, the base 30 of each independent bending section 3 is fixed to the sheet metal, and the bending curvature is fixed accordingly. Finally, the strap 41 of each bending section 3 passes over the wire harness and locks with the locking head 40 to press and fix the wire harness segmentally to each bending section 3. In this way, the entire bending section of the wire harness is continuously supported and fixed by the bending section 3 at both ends and in the middle, avoiding the wire harness from sagging or vibrating due to lack of support in the long span bending section.

[0040] Then, adjust the bending section 3 according to the actual direction and hardness of the wire harness. The starting end of each group of bases 30 is connected to the base 2, and the end of each group of bases 30 is a free end. The operator bends the two groups of bases 30 on the left and right sides of the base 2 according to the actual turning direction and turning angle of the wire harness. When each base 30 rotates relative to the hinge point, the included angle between adjacent bases 30 changes. When the included angle of all bases 30 is adjusted to the correct position, the bending section 3 forms an arc track that smoothly transitions from the base 2 to the target direction.

[0041] For wire harnesses of different hardness, the operator adjusts the bending radius by using different bending arcs. When the wire harness to be fixed is relatively soft, the operator bends each base 30 into a large arc with a gentle bend, so that the wire harness has a sufficiently large bending radius at the turning point, avoiding the wire harness from becoming stuck due to an insufficient bending radius, which would damage the internal wires. When the wire harness to be fixed is relatively hard, the operator bends each base 30 into a smaller arc, so that the wire harness runs along a smoother path, avoiding the wire harness from generating a large rebound force and stress concentration due to forced large arc bending, and preventing the wire harness from loosening the clip 1 or pulling the terminal out of the connector during long-term use. After each base 30 is bent, the bending part 3 as a whole forms an arc-shaped track that matches the direction of the wire harness. The wire harness runs along this arc-shaped track, and the turning point is continuously supported.

[0042] The two limiting blocks 31 on each base 30 form a clamping space for accommodating the wire harness. The limiting blocks 31 on each base 30 are located on the upper surface of the base 30. The left and right limiting blocks 31 are arranged opposite each other along the width direction of the base 30, and the distance between them constitutes the clamping space. When the wire harness is placed in the clamping space, the two limiting blocks 31 are located on the left and right sides of the wire harness respectively, which initially restricts the lateral displacement of the wire harness.

[0043] Next, place the wire harness into the clamping space. Then, holding the free end of the strap 41, pass the strap 41 over the wire harness and pull it toward the locking head 40 on the base 2 or the limiting block 31 on the same side of the base 2. The operator inserts the free end of the strap 41 into the wire passage of the locking head 40 and then pulls the strap 41 to gradually tighten it. As the strap 41 tightens, the part of the strap 41 that passes over the wire harness presses the wire harness downward, and the wire harness is pressed downward into the clamping space. Finally, the wire harness is pressed and fixed in the clamping space. The strap 41 and the locking head 40 have a one-way locking function. After the strap 41 is tightened, it automatically locks in the locking head 40 and cannot be loosened in the opposite direction. After the wire harness is completely pressed and fixed, the operator stops pulling the strap 41. The strap 41 and the locking head 40 lock together to maintain a continuous pressure on the wire harness.

[0044] After the bending and fixing of the wire harness are completed, the operator directly attaches the lower end of the base 30 to the sheet metal surface, aligning the opening of the glue injection channel 300 with the sheet metal surface. Then, glue is injected into the contact surface between the base 30 and the sheet metal through the glue injection channel 300. The glue flows along the glue injection channel 300 and is evenly distributed between the contact surfaces of the base 30 and the sheet metal. After the glue cures, the base 30 is firmly fixed to the sheet metal, and the adjusted bending curvature is thus fixed and will not change due to vibration or external force.

[0045] When it is necessary to adjust the wiring harness routing or replace the wiring harness, the operator releases the locking engagement between the locking head 40 and the strap 41. The strap 41 loosens, and the wiring harness can be taken out from the clamping space. After repositioning the wiring harness, the strap 41 is passed over the wiring harness and inserted into the locking head 40 again and tightened to complete the re-fixing. If it is necessary to change the curvature, a special method must be used to remove the cured glue before the hinge angle of each base 30 can be readjusted.

[0046] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, pin holes are provided on both the left and right sides of the base 2. A pin shaft 301 is fixedly installed on the side of the base 30 near the base 2, and a pin hole is provided on the other side of the base 30. The pin shaft 301 of the base 30 passes through the pin hole on the base 2, so that the base 30 is rotatably installed on the base 2. Adjacent bases 30 are connected by hinged connection through the pin shaft 301 of one base 30 passing through the pin hole of the other base 30.

[0047] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the extended connection part 5 includes a plug groove 50 disposed at one end of the base 2 and a plug block 51 disposed at the other end of the base 2. The plug block 51 is plugged into the plug groove 50 of the other base 2.

[0048] like Figure 1 and Figure 2 As shown, a connecting plate 6 is fixedly installed on the pin 301, and a limiting post 7 is fixedly installed on the connecting plate 6. The limiting post 7 is used to limit the relative rotation angle between adjacent bases 30.

[0049] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the cross-sections of the insertion slot 50 and the insertion block 51 are T-shaped.

[0050] like Figures 1 to 5As shown, in specific operations, the operator takes a base 30 and inserts the pin 301 of the base 30 near the base 2 into the pin hole on the side of the base 2, so that the base 30 rotates around the pin 301 and is installed on the base 2, completing the installation of the first base 30. Then, the operator takes a second base 30 and inserts the pin 301 of the second base 30 near the base 2 into the pin hole on the other side of the first base 30, so that the second base 30 rotates around the pin 301 and is installed on the first base 30. In this way, the pins 301 of the subsequent bases 30 are sequentially inserted into the pin holes of the previous bases 30. The bases 30 are connected in series along the length direction to form a complete set of bases 30. The other set of bases 30 is installed in series on the other side of the base 2 in the same way. The bases 30 can rotate relative to each other around the pin 301. The operator bends each base 30 according to the actual direction of the wire harness, so that the bent part 3 forms an arc track that matches the direction of the wire harness.

[0051] During the relative rotation of each base 30, the connecting plate 6 fixedly mounted on the pin 301 rotates synchronously with the pin 301, and the limiting post 7 fixedly mounted on the connecting plate 6 moves accordingly. When the operator bends each base 30 to gradually bend the curved part 3 from a straight state, the included angle between adjacent bases 30 increases. The limiting post 7 gradually moves away from the adjacent base 30 as the pin 301 rotates. When there is no contact between the limiting post 7 and the adjacent base 30, each base 30 can continue to rotate, and the adjustment of the bending arc continues. When the operator needs to restore the curved part 3 to a straight state, the operator bends each base 30 in the opposite direction to gradually reduce the included angle between adjacent bases 30. As the pin 301 rotates in the opposite direction, the limiting post 7 gradually approaches the adjacent base 30. When the included angle between the adjacent base 30 decreases to a straight state, the outer circumferential surface of the limiting post 7 abuts against the end face of the adjacent base 30 or the base 2, forming a mechanical block to prevent the pin 301 from continuing to rotate in the opposite direction. During the bending process, the operator can feel the resistance generated when the limiting post 7 abuts against the adjacent base 30, thus knowing that the bent part 3 has returned to a straight state and cannot continue to rotate in the straight direction. The limiting effect of the limiting post 7 allows the bent part 3 to accurately return to a straight position when it needs to be flattened, avoiding excessive reverse bending that could cause the wire harness to be stretched or squeezed and damaged.

[0052] The base 2 has two mutually mating extended connection parts 5 at its two ends. Each extended connection part 5 includes a insertion groove 50 at one end of the base 2 and an insertion block 51 at the other end of the base 2. The operator pre-applies adhesive to the part of the lower end face of the base 2 that contacts the sheet metal, then aligns the insertion block 51 at one end of the first base 2 with the insertion groove 50 at the other end of the second base 2, and pushes the insertion block 51 into the insertion groove 50 along the insertion direction. As the insertion block 51 gradually slides into the insertion groove 50, the two bases 2 gradually approach each other along the length direction and are positioned relative to each other. When the insertion block 51 is fully inserted into the insertion groove 50, the two bases 2 are fixedly connected along the length direction. At the same time, the lower end face of the base 2 is in contact with the sheet metal surface, and the pre-applied adhesive contacts the sheet metal surface and begins to cure, thus bonding and fixing the base 2 to the sheet metal surface. On the sheet metal, while the extended connection part 5 completes the insertion and engagement, the base 2 also completes the adhesive fixation to the sheet metal. The two operation steps are completed simultaneously. The cross-section of the insertion groove 50 and the insertion block 51 is a T-shaped structure. The outer contour of the insertion block 51 is T-shaped, and the inner contour of the insertion groove 50 is a T-shaped that matches the outer contour of the insertion block 51. When the insertion block 51 is inserted into the insertion groove 50, the lateral part of the T-shaped structure interlocks with each other, which restricts the relative displacement of the two bases 2 in the direction perpendicular to the insertion direction, allowing only relative sliding along the insertion direction. After the insertion block 51 is inserted into place, the adhesive further fixes the base 2 and the sheet metal in the direction perpendicular to the sheet metal surface. The two work together to ensure that the overall structure after series combination remains stable in the vehicle vibration environment and will not be misaligned or detached due to vibration.
