They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific position, be constructed and operated in a specific position, and therefore cannot be understood as limiting the present invention. In addition, the terms "first", "second", "third", etc. are only used to distinguish the description, and cannot be understood as indicating or implying relative importance.

[0028] like Figure 1-6 As shown, a vehicle wiring harness positioning device comprises a fixing seat 1 and a positioning clamp 2 fixedly arranged with the fixing seat 1, the positioning clamp 2 is a C-shaped structure with its opening arranged toward the fixing seat 1, the inner ring and the outer ring of the positioning clamp 2 are coated with a tightenable positioning belt 3, a tightening reel is arranged on the side of the positioning clamp 2 away from the fixing seat 1, two ends of the positioning belt 3 are connected to the tightening reel, the axis of the tightening reel is connected with an auxiliary tube, after an auxiliary medium is passed into the auxiliary tube, the auxiliary medium drives the tightening reel to rotate, and the positioning belt 3 is tightened, the fixing seat 1 is provided with a locking wheel 4, and the locking wheel 4 is in close contact with the positioning belt 3.

[0029] The arc surface of the positioning clamp 2 can be provided with a groove, and the positioning belt 3 is laid in the groove so that the positioning belt 3 will not come off the positioning clamp 2. Correspondingly, a limit block can also be provided on the groove to limit the positioning belt 3 and prevent the positioning belt 3 from loosening.

[0030] like Figure 1As shown, the take-up reel includes a connecting sleeve 5 and a fixed roller 6, the connecting sleeve 5 is rotatably connected to the outer ring of the fixed roller 6, the auxiliary tube includes an A tube 7 and a B tube 8, the A tube 7 is an inlet tube, the B tube 8 is an outlet tube, and one end of the A tube 7 is connected to one end of the B tube 8;

[0031] The outer ring of the A tube 7 is provided with a driving groove 9 , which is in contact and sealed with the inner ring of the connecting sleeve 5 . The inner side of the connecting sleeve 5 is evenly provided with driving blades 10 , and the driving groove 9 is used to accommodate the driving blades 10 .

[0032] A sealing gasket is arranged between the connecting sleeve 5 and the fixed roller 6 to prevent the auxiliary medium from overflowing. The auxiliary medium can be liquid or gas. Both gas and liquid can push the driving blade 10 to move, drive the connecting sleeve 5 to rotate, and realize the tightening of the positioning belt 3.

[0033] Correspondingly, a motor may also be provided to drive the axis direction of the fixed roller 6. When a motor is provided to drive, the installation cost will increase, and it is difficult to drive multiple fixed rollers 6 at the same time.

[0034] like Figure 4 As shown, the axis of the locking wheel 4 is arranged parallel to the axis of the positioning clamp 2, and two locking wheels 4 are provided. The two locking wheels 4 are respectively arranged at the upper opening of the positioning clamp 2 and the lower opening of the positioning clamp 2. The two locking wheels 4 rotate in opposite directions, and the locking wheel 4 is driven to rotate when the positioning belt 3 is tightened.

[0035] The locking wheel 4 can only perform a single reverse rotation and can be a ratchet. The distance between the locking wheel 4 and the positioning clamp 2 is less than the thickness of the positioning belt 3.

[0036] like Figure 5 and Figure 7 As shown, an inclined auxiliary channel 11 is provided inside the opening of the positioning clamp 2, and an auxiliary component is provided inside the auxiliary channel 11;

[0037] The auxiliary component includes an auxiliary rod 12, and an auxiliary roller 13 is connected to the end of the auxiliary rod 12 opposite to the opening of the positioning clamp 2, and a cutter 14 is connected to the other end of the auxiliary rod 12. A limiting ring is arranged in the middle of the auxiliary rod 12, and a supporting spring 15 is arranged between the limiting ring and the auxiliary channel 11. Under the action of the supporting spring 15, the auxiliary roller 13 contacts the inner ring of the positioning belt 3. When the positioning belt 3 is tightened, the positioning belt 3 squeezes the auxiliary rod 12 to move outward, and the positioning belt 3 is cut off by the cutter 14.

[0038] When the positioning belt 3 is not tightened, the force of the positioning belt 3 on the auxiliary rod 12 is less than the downward elastic force of the supporting spring 15 on the auxiliary rod 12. When the positioning belt 3 is tightened, the force of the positioning belt 3 on the auxiliary roller 13 is greater than the downward elastic force of the supporting spring 15 on the auxiliary rod 12. Therefore, when the positioning belt 3 is tightened, the auxiliary rod 12 can be pushed upward, and the positioning belt 3 can be cut by the cutter 14 at the upper end of the auxiliary rod 12.

[0039] When the cutter 14 rises upward, it provides a shearing force to the positioning belt 3 at that position, making it easier for the positioning belt 3 to be pulled apart, so there is no requirement for the sharpness of the cutter 14 .

[0040] In order to facilitate cutting of the positioning belt 3 , the positioning belt 3 should also be made of a material that has a certain degree of elasticity and is easy to cut.

[0041] like Figure 1 As shown, the fixed roller 6 is provided with a positioning assembly 16, and the positioning assembly 16 is a triangular structure. The positioning assembly 16 is connected to multiple fixed rollers 6 at the same time, and the outer end of the positioning assembly 16 is connected to a fixing facility;

[0042] The positioning assembly 16 is arranged parallel to the auxiliary pipe.

[0043] The positioning assembly 16 is used to support and fix the multiple take-up reels to prevent the take-up reels from rotating with the connecting sleeve 5 .

[0044] like Figure 7 As shown, the auxiliary channel 11 passes through the positioning clamp 2, and the lower end of the auxiliary channel 11 gradually opens to form a receiving portion, which is used to receive the auxiliary roller 13, and the roller surface of the auxiliary roller 13 is a rough surface;

[0045] The middle part of the auxiliary channel 11 is gathered to form a limiting portion, and the diameter of the limiting ring is greater than the opening width of the limiting portion.

[0046] The auxiliary tube is connected to a plurality of take-up reels at the same time, and the axis of the take-up reel is parallel to the axis of the auxiliary tube.

[0047] The width of the cutter 14 is not less than the width of the positioning belt 3, and the surface of the positioning belt 3 is rough.

[0048] Directions:

[0049] When the device is used, the positioning assembly 16 is used to support multiple positioning clamps 2. The positioning assembly 16 can be straight or curved to follow the internal structure of the car. The length of the auxiliary pipe is set along the length direction of the positioning assembly 16.

[0050] When positioning the wire harness, the positioning belt 3 is laid in contact with the inner wall of the positioning clamp 2, and the wire harness is first passed through the axial direction of the fixed clamp;

[0051] The auxiliary medium is introduced through the A tube 7, and the auxiliary medium pushes the driving blade 10 to move, driving the connecting sleeve 5 to rotate around the fixed roller 6. During the rotation of the connecting sleeve 5, the positioning belt 3 is rolled up, so that the positioning belt 3 is gradually tightened to fix the wire harness;

[0052] As the positioning belt 3 is tightened, the positioning belt 3 squeezes the auxiliary roller 13, so that the auxiliary rod 12 is lifted upward along the auxiliary channel 11. The cutting of the upper end of the auxiliary rod 12 cuts off the positioning belt 3, and the tightening reel can be separated from the positioning clamp 2. At the same time, the locking wheel 4 squeezes the positioning belt 3 to prevent the positioning belt 3 from falling off.

[0053] The above-mentioned specific implementation is only a specific case of the present invention. The patent protection scope of the present invention includes but is not limited to the product form and style of the above-mentioned specific implementation. Any appropriate changes or modifications made to the automotive wiring harness positioning device in accordance with the claims of the present invention and any ordinary technicians in the corresponding technical field shall fall within the patent protection scope of the present invention.
