Description

Technical Field

[0001] This utility model relates to the field of automotive wiring harness technology, and more specifically, to an automotive wiring harness with adjustable tightness. Background Technology

[0002] Automotive wiring harnesses, also known as low-voltage wiring harnesses, differ from ordinary household wiring harnesses. Ordinary household wiring harnesses are single-core copper wires with a certain degree of rigidity. Automotive wiring harnesses, on the other hand, are multi-core copper wires, some as thin as a hair. Several or even dozens of soft copper wires are wrapped in a plastic insulating tube (polyvinyl chloride), making them flexible and not easily broken.

[0003] With the increasing intelligence and connectivity of automobiles, the overall functions of automobiles are increasing, which requires more wiring harnesses to connect various functional modules. However, in the current technology, automobile wiring harnesses are mostly tied to the vehicle frame with cable ties. If the wiring harness is tied too tightly, it will be torn and damaged if it is hit during driving. If it is tied too loosely, the wiring harness will wobble and cannot be loosened freely. New cable ties must be used to fix the same parts next time, which is wasteful and affects the efficiency of automobile wiring harness assembly. Utility Model Content

[0027] To make the technical problems, technical solutions and advantages of this utility model clearer, a detailed description will be given below in conjunction with the accompanying drawings and specific embodiments.

[0028] As attached Figure 1 To be continued Figure 4 As shown, an embodiment of this utility model provides an adjustable tightness automotive wiring harness, including a mounting base 1, an adjusting wire box 2, and a fixing cover 3. The adjusting wire box 2 is detachably mounted on the top of the mounting base 1, and the fixing cover 3 is detachably mounted on the top of the adjusting wire box 2. A connecting wire 4 is sleeved inside the adjusting wire box 2.

[0029] like Figure 4 As shown, the adjusting wire box 2 includes a rotating wire box 21 and a rotating wire wheel 24. Both ends of the rotating wire box 21 are provided with wire holes 23. Connecting blocks 22 are fixedly installed on both sides inside the rotating wire box 21. The rotating wire wheel 24 is rotatably installed inside the rotating wire box 21. A support rod 25 is fixedly installed on one side of the rotating wire wheel 24. A one-way ratchet 26 is fixedly sleeved on the outer surface of the upper end of the rotating wire wheel 24. A star-shaped groove 27 is provided on the top of the rotating wire wheel 24.

[0030] Using the support rod 25, the connecting wire 4 is sleeved on the outer surface of the support rod 25. One end of the connecting wire 4 passes through one side of the pressing wheel 211 on the left side of the rotating wire box 21, and the other end of the connecting wire 4 passes through the other side of the pressing wheel 211 on the right side. The connecting wire 4 is wound and connected on the outer surface of the rotating wire wheel 24. The star rod 37 rotates inside the star groove 27, which controls the rotation of the rotating wire wheel 24 inside the rotating wire box 21, thereby causing the rotating wire wheel 24 to wind up the connecting wire 4 and adjust the tightness of the connecting wire 4.

[0031] Both ends of the rotating wire box 21 are fixedly installed with fixing rods 28. Rotating rods 29 are rotatably installed on the outer surface of the fixing rods 28. Both ends of the rotating wire box 21 are fixedly installed with arc-shaped frames 210. The arc-shaped frames 210 are located on one side of the wire hole 23. A pressing wheel 211 is rotatably installed on the top of the end of the rotating rod 29 away from the fixing rods 28.

[0032] The top of the arc-shaped frame 210 is provided with an arc-shaped groove. One end of the rotating rod 29 is slidably installed on the side of the arc-shaped frame 210. The pressing wheel 211 is slidably installed on the top of the arc-shaped frame 210. Movable springs 212 are fixedly installed on both sides of one end of the rotating rod 29. The other ends of the two movable springs 212 are fixedly installed on the inner walls of both ends of the arc-shaped frame 210.

[0033] The movable spring 212 causes the pressing wheel 211 to press the side of the connecting wire 4. When the connecting wire 4 is suddenly pulled, the pressing wheel 211 will be squeezed by the connecting wire 4 on the side, causing the movable spring 212 to contract inside the arc frame 210. The rotating rod 29 rotates around the fixed rod 28, which in turn causes the pressing wheel 211 to rotate inside the rotating wire box 21, buffering one side of the connecting wire 4 and preventing the connecting wire 4 from being suddenly pulled and damaged.

[0034] The connecting wire 4 is wound around the sides of the pressing wheels 211 at both ends, the connecting wire 4 is wound around the outer surface of the support rod 25, and the two ends of the connecting wire 4 are wound and connected to the outer surface of the rotating wheel 24.

[0035] like Figure 5 and Figure 6 As shown, a mounting plate 213 is rotatably mounted on the bottom of the rotating junction box 21. A positioning rod 214 is fixedly mounted on the bottom of the mounting plate 213. A snap-fit ​​block 215 is fixedly mounted on both sides of the bottom of the mounting plate 213. The snap-fit ​​block 215 is made of elastic material.

[0036] The rotating wire box 21 rotates on the top of the mounting plate 213, allowing it to rotate freely according to the orientation of the connecting wire 4. This ensures that the wire holes 23 at both ends of the rotating wire box 21 correspond to the orientation of the connecting wire 4, thereby improving the flexibility of the device.

[0037] The positioning rod 214 is inserted into the inside of the limiting hole 12, and the snap-fit ​​block 215 is inserted into the inside of the embedded hole 13 and snap-fitted onto the side of the snap-fit ​​groove 14.

[0038] Using the elastic material of the snap-fit ​​block 215, press the snap-fit ​​block 215 to move it out of the snap-fit ​​groove 14, and pull up and rotate the wire box 21 to pull the snap-fit ​​block 215 out of the embedded hole 13, so that the mounting base 1 is separated from the adjustment wire box 2, thereby facilitating the maintenance and adjustment of the inside of the adjustment wire box 2.

[0039] like Figure 3 As shown, the fixed cover 3 includes a cover plate 31, an elastic card 36, and a star-shaped rod 37. A rotating knob 32 is rotatably installed inside the cover plate 31. The bottom of the rotating knob 32 is fixedly installed with the star-shaped rod 37. Inner blocks 34 are fixedly installed on both sides of the bottom of the cover plate 31. Fixing bolts 33 are installed in the internal threads of the inner blocks 34. A fixing ring 35 is fixedly installed on the bottom of the cover plate 31. The elastic card 36 is fixedly installed on one side of the inner wall of the fixing ring 35. The elastic card 36 is made of elastic material.

[0040] The cover plate 31 is installed on the top of the rotating wire box 21, the fixing bolt 33 is threaded on the top of the connecting block 22, the inner block 34 is located on the top of the connecting block 22, the star rod 37 is embedded in the inside of the star groove 27, and the elastic card 36 is snapped on the side of the one-way ratchet 26.

[0041] The elastic card 36 engages with the side of the one-way ratchet 26. By rotating the knob 32, the star-shaped rod 37 rotates counterclockwise through the star-shaped groove 27, causing the rotating thread wheel 24 to rotate. The support rod 25 allows the connecting wire 4 to wind around the outer surface of the rotating thread wheel 24. At the same time, the elastic card 36 engages with the side of the one-way ratchet 26, ensuring that the rotating thread wheel 24 can only rotate counterclockwise, preventing wobbling and causing the rotating thread wheel 24 to rotate in the opposite direction, thus avoiding affecting the tightness of the connecting wire 4.

[0042] like Figure 2 and Figure 6 As shown, the mounting base 1 includes a fixed base 11, an adhesive film 15 is fixedly installed on the bottom of the fixed base 11, a limiting hole 12 is opened on the top of the fixed base 11, an embedded hole 13 is opened on both sides of the top of the fixed base 11, and a snap-fit ​​groove 14 is opened on both sides of the fixed base 11, the snap-fit ​​groove 14 is connected to the embedded hole 13.

[0043] By setting the adhesive film 15, the fixed base 11 can be freely installed in any position, so that the connecting wire 4 can be fixed in any position, improving the convenience of device installation.

[0044] The working process of this utility model is as follows:

[0045] In use, the connecting wire 4 passes through the wire holes 23 at both ends of the rotating wire box 21, so that the connecting wire 4 is sleeved on the outer surface of the support rod 25. At the same time, both ends of the connecting wire 4 are wrapped around the outer surface of the rotating wire wheel 24. Meanwhile, one end of the connecting wire 4 passes through one side of the pressing wheel 211 on the left side of the rotating wire box 21, and the other end of the connecting wire 4 passes through the other side of the pressing wheel 211 on the right side, so that the connecting wire 4 is wrapped around the outer surface of the rotating wire wheel 24. Rotating the rotating knob 32, using the star-shaped rod 37 to rotate the star-shaped rod 25, the connecting wire 4 is connected to the outer surface of the rotating wire wheel 24. The rotation inside the slot 27 controls the rotation of the rotating wire wheel 24 inside the rotating wire box 21, causing the rotating wire wheel 24 to wind up the connecting wire 4. The elastic card 36 is engaged with the side of the one-way ratchet 26, thereby adjusting the tightness of the connecting wire 4. When the connecting wire 4 needs to be loosened, the cover plate 31 is moved out from the top of the rotating wire box 21 by the fixing bolt 33, the elastic card 36 is moved out from the side of the one-way ratchet 26, and the connecting wire 4 is pulled to both ends, causing the rotating wire wheel 24 to rotate in the opposite direction, thereby loosening the connecting wire 4.

[0046] Furthermore, the movable spring 212 causes the pressing wheel 211 to press the side of the connecting wire 4. When the connecting wire 4 is suddenly pulled, the pressing wheel 211 will be squeezed by the connecting wire 4 on the side, allowing the movable spring 212 to extend and retract inside the arc frame 210. The rotating rod 29 rotates around the fixed rod 28, thereby causing the pressing wheel 211 to rotate inside the rotating wire box 21, buffering one side of the connecting wire 4 and preventing the connecting wire 4 from being suddenly pulled and damaged.

[0047] Finally, it should be noted that: the accompanying drawings of the embodiments disclosed in this utility model only involve the structures involved in the embodiments disclosed in this utility model. Other structures can refer to the general design. In the absence of conflict, the same embodiment and different embodiments of this utility model can be combined with each other.
