Description

Technical Field

[0001] The present invention relates to the technical field of automotive wiring harnesses, and particularly to an automotive wiring harness positioning device. Background Art

[0002] Automotive wiring harnesses run through the entire vehicle body and are key components of the vehicle. The reliability of the wiring harness fixation is directly related to the safety and reliability of the entire vehicle. An automotive wiring harness is composed of a main wiring harness and several wiring harness branches. The wire diameter of the wiring harness branches must be smaller than that of the branch wires. Due to different wrapping materials for the wiring harness (such as being wrapped with corrugated pipes or flannelette), different wrapping methods result in different wire diameters of the wiring harness. During the wiring harness design process, the safety designer at the wiring harness branch point position must design two or more fixing points (the fixing points are generally designed according to the number of branches). Only in this way can the reliability of the wiring harness fixation be ensured. The reliable fixation of the automotive wiring harness is very important for the vehicle assembly.

[0003] Chinese Patent Application No. CN202221432869.X discloses an automotive wiring harness positioning device, which includes a bottom plate, a first clamping plate, and a top rod. One side of the first clamping plate is fixedly installed with a connecting rod, and the side of the first clamping plate away from the connecting rod is fixedly installed with a first fixing member. A clamping component is arranged between the top rod and the first clamping plate. The clamping component includes a second clamping plate and a second fixing member. A fixing block is fixedly connected inside the second fixing member. An outer frame is sleeved outside the fixing block. One side of the outer frame away from the first fixing member is fixedly connected with a pull rod. One end of the pull rod away from the outer frame is fixedly connected with a pull head. A limiting spring is fixedly installed at one end of the fixing block inserted into the inner side of the outer frame. One end of the limiting spring away from the fixing block is fixedly connected with a push block. This automotive wiring harness positioning device can avoid the situation of interference, crossing, or covering between multiple groups of wiring harnesses, reduce the electrical interference between multiple groups of wiring harnesses, and ensure the signal transmission of the wiring harness.

[0004] However, the existing wiring harness positioning devices still have some defects. The fixing angle of the positioning device cannot be adjusted according to the angle of the automotive wiring harness, resulting in automotive wiring harnesses with different angles being easily affected by bending during positioning, causing the automotive wiring harnesses to fall off.

[0028] It should be noted that the terms "front", "rear", "left", "right", "upper" and "lower" used in the following description refer to the directions in the drawings, and the terms "inner" and "outer" respectively refer to the directions towards or away from the geometric center of a specific component.

[0029] In order to make the content of the present invention easier to be clearly understood, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention.

[0030] As Figures 1 to 8 shown, an automotive wire harness positioning device includes a base 1. Fixed seats 2 are installed in pairs on the upper surface of the base 1. A slide bar 3 is installed between the fixed seats 2. An adjusting seat 4 is slidably connected to the slide bar 3. A displacement mechanism 5 is installed on one side of the adjusting seat 4. A switch seat 6 is installed on the upper surface of the adjusting seat 4. A rotating shaft 7 is rotatably connected to the middle of the upper surface of the adjusting seat 4. The top end of the rotating shaft 7 is connected to a first mounting seat 8. A second mounting seat 9 is sleeved on the first mounting seat 8. A buffer mechanism 10 is installed on the second mounting seat 9. A limiting mechanism 11 is connected between the rotating shaft 7 and the switch seat 6;

[0031] The switch seat 6 is a cavity. The limiting mechanism 11 includes a movable rod 1101 sleeved on the switch seat 6. A limiting seat 1102 is installed at one end of the movable rod 1101. A handle 1103 is installed at the other end of the movable rod 1101. A guide rod 1104 is connected to the inner wall of the switch seat 6. A return spring 1105 is installed on the guide rod 1104. A gear 1106 is sleeved on the rotating shaft 7.

[0032] Through the above solution, when the user pulls the pull ring 503, the limit rod 502 will be pulled out from the positioning hole 102. At this time, the adjusting seat 4 can slide freely. After releasing the pull ring 503, the telescopic spring 504 pushes the limit rod 502 to re-insert into the positioning hole 102 to achieve position fixation, enhancing the adjustment flexibility of the device. Also, through the insertion connection between the limit rod 502 and the positioning hole 102, the stability of the adjusted position is ensured, and the positioning accuracy is improved.

[0033] The displacement mechanism 5 includes a mounting plate 501 fixedly installed on one side of the adjusting seat 4. A limit rod 502 is sleeved on the mounting plate 501. A pull ring 503 is installed at the top end of the limit rod 502. A telescopic spring 504 is connected between the bottom end of the pull ring 503 and the upper surface of the adjusting seat 4.

[0034] Mounting holes 101 are opened at both ends of the upper surface of the base 1, and a positioning hole 102 is opened at the middle of the upper surface of the base 1. The limit rod 502 is inserted and connected with the positioning hole 102.

[0035] Through the above solution, when the user pulls the pull ring 503, the limit rod 502 will be pulled out from the positioning hole 102. At this time, the adjusting seat 4 can slide freely. After releasing the pull ring 503, the telescopic spring 504 pushes the limit rod 502 to re-insert into the positioning hole 102 to achieve position fixation, enhancing the structural stability, preventing shaking or falling off during driving, and thus improving driving safety.

[0036] The buffer mechanism 10 includes a buffer seat 1001 movably connected to the second mounting seat 9. Sliders 1002 are connected to both ends of the buffer seat 1001. Positioning blocks 1004 are installed in pairs at the bottom end of the buffer seat 1001. Buffer springs 1005 are sleeved on the positioning blocks 1004. A buffer pad 1003 is installed on the upper surface of the buffer seat 1001.

[0037] Through the above solution, the buffer seat 1001 is movably connected to the second mounting seat 9 and is slidably connected to the inner wall rail 903 of the second mounting seat 9 through the sliders 1002. When the wire harness or other components are impacted, the buffer seat 1001 will move downward, compressing the buffer springs 1005, thereby absorbing the impact energy. The setting of the buffer pad 1003 further enhances the buffer effect and protects the wire harness from damage.

[0038] Auxiliary rods 901 are installed in pairs at the top end of the second mounting seat 9. Mounting holes 902 are provided on the second mounting seat 9. Rails 903 are provided on the inner wall of the second mounting seat 9. The sliders 1002 are slidably connected to the rails 903.

[0039] A threaded rod 802 is installed at the top end of the first mounting seat 8. Jacks 801 are provided on both sides of the threaded rod 802. A fixing nut 803 is threadedly connected to the top end of the threaded rod 802.

[0040] Through the above solution, the top of the first mounting seat 8 is provided with a threaded rod 802 and a jack 801. Users can fix the wire harness or other components by threadedly connecting and fixing nuts 803. In addition, the second mounting seat 9 is provided with mounting holes 902 to facilitate connection with other components. This design makes the installation and adjustment process of the entire device more convenient.

[0041] The gear 1106 is inserted and connected with the limit seat 1102.

[0042] Pairs of auxiliary blocks 401 are installed at the bottom end of the adjusting seat 4, and sliding holes 402 matching the sliding rod 3 are formed in the auxiliary blocks 401.

[0043] Through the above solution, the mounting hole 101 facilitates firmly mounting the entire device on the vehicle. At the same time, the design of the auxiliary block 401 at the bottom end of the adjusting seat 4 and the sliding hole 402 thereon ensures the sliding stability of the adjusting seat 4 on the sliding rod 3, reducing shaking and noise.

[0044] The usage process of this invention patent: Place the base 1 steadily at the predetermined position, ensure that the mounting hole 101 on the upper surface of the base 1 is aligned with the fixed position, use bolts to fixedly install the base 1 through the mounting hole 101. The adjusting seat 4 cooperates with the sliding rod 3 through the auxiliary block 401 and the sliding hole 402 at its bottom end to ensure that the adjusting seat 4 can move freely along the sliding rod 3. When it is necessary to fix the position of the adjusting seat 4, pull up the pull ring 503 at the top end of the limiting rod 502 to insert the limiting rod 502 into the positioning hole 102 on the base 1 and maintain the limiting state through the telescopic spring 504. Install the guiding rod 1104 on the inner wall of the switch seat 6 and install a return spring 1105 on the guiding rod 1104. Sleeve the gear 1106 on the rotating shaft 7 and insert and connect it with the limit seat 1102 to ensure that the limiting mechanism 11 can work properly. Adjust the position of the adjusting seat 4 as needed and perform fine adjustment through the displacement mechanism 5 to ensure that the vehicle wire harness can be accurately positioned. After the position of the adjusting seat 4 is adjusted, use the fixing nut 803 to fix the first mounting seat 8 and the second mounting seat 9 together through the threaded rod 802 to prevent the vehicle wire harness from shaking during transportation or use.

[0045] The above are only the preferred embodiments of this invention patent and are not intended to limit this invention patent. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of this invention patent shall be included within the protection scope of this invention patent.
