Description

Technical Field

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

[0002] With the increase of automotive electronic functions, the layout of electronic wire harnesses is a huge challenge. The layout and fixing of electronic wire harnesses play an important role in the performance and reliability of the whole vehicle. If the layout or fixing of the electronic wire harness is unreasonable, abnormal noises may occur or the functions of certain automotive components may fail, seriously affecting driving safety and also bringing great trouble to the subsequent automotive maintenance work.

[0003] The existing methods for fixing automotive wire harnesses are to directly use cable ties and buckles at the bends of the wire harnesses, or directly use fixed wire harness molds. However, the shapes of the wire harness molds are fixed, and the automotive wire harnesses will gather and wind together in the wire harness molds. When it is necessary to adjust or repair the target wire harness, it is difficult to individually adjust or repair the target wire harness because multiple wire harnesses are gathered together. It is often necessary to cut the cable ties or open the buckles to find the target wire harness from the gathered wire harnesses for adjustment or repair, bringing great trouble to the adjustment or repair work of the wire harness.

[0004] The Chinese invention patent with the application number CN202410351615.2 discloses an automotive wire harness centralized fixing device, which controls the movement of the outer support rod and the outer transmission rack as well as the inner support rod and the inner transmission rack by the mutual attraction of the electromagnet one and the electromagnet two, and then controls the rotation of the outer transmission gear ring and the outer scissors plate as well as the inner transmission gear ring and the inner scissors plate, and the adjusting pressing plate presses and fixes all the wire harnesses. At the same time, the linkage control makes the extrusion shaft press down, and the pressing plate loosens the wire harness. At the same time, by the mutual attraction of the electromagnet three and the electromagnet four, the wire harness is pulled forward to automatically adjust the lengths of both ends of the wire harness. However, when installing the above fixing device, it is necessary to fixedly connect each wire harness roller and the two adjusting movable frames to the inner wall of the vehicle to ensure the stability of the fixing device. Due to the large number of wire harness rollers, this brings trouble to the installation work of the fixing device, reducing the practicability and convenience of the fixing device. Summary of the Invention

The pinch roller is fixedly connected to the top of the lifting plate. The linkage assembly further includes two driving rods symmetrically and fixedly connected to the bottoms of the two moving plates. The two driving rods respectively abut against the sides of the two rectangular blocks away from each other. The advantage of this setting is that it automatically completes the approach operation between the pinch roller and the conical surfaces of the two conical rollers, further simplifies the clamping operation of the wire harness, ensures the clamping effect on the wire harness, and improves the practicability and convenience of the fixing device.

[0017] Preferably, the thickness of the fixing plate is not less than half of the length of the first hinge rod, and the lengths of the first hinge rod and the second hinge rod are equal.

All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0036] Please refer to Figures 1 - 10 a shown automotive wire harness fixing device, which includes:

[0037] A plurality of clamping assemblies 1, the clamping assembly 1 includes a base plate 11, the top of the base plate 11 is symmetrically and movably connected with two moving plates 12 through first elastic members, two tapered rollers 13 are symmetrically rotatably connected to the side surfaces of the two moving plates 12 close to each other, a clamping roller 14 is connected to the top of the base plate 11, and the clamping roller 14 is located directly below the two tapered rollers 13 and cooperates with the tapered inclined surfaces of the two tapered rollers 13 to clamp the wire harness;

[0038] A plurality of connecting assemblies 2, which are used to sequentially and movably connect a plurality of clamping assemblies 1 together from left to right. The connecting assembly 2 includes a first hinge rod 21 and a second hinge rod 22. The first hinge rod 21 and the second hinge rod 22 are hinged together through a hinge shaft 23. The first hinge rod 21 and the second hinge rod 22 are respectively hinged to the right side surface and the left side surface of the base plate 11. The connecting assembly 2 includes a fixing mechanism 24, and the fixing mechanism 24 is used to fix the hinged first hinge rod 21 and second hinge rod 22 to prevent the two from moving;

[0039] Two fixed plates 3, which are respectively hinged to the left end of the second hinge rod 22 on the leftmost side and the right end of the first hinge rod 21 on the rightmost side, and the fixed plates 3 are fixedly connected to the inner wall of the vehicle.

[0040] Reference Figure 2 、 Figure 3 、 Figure 5 、 Figure 8 and Figure 9 , The connecting assembly 2 further includes a through cavity 25 opened at the top of the first hinge rod 21. The connecting assembly 2 further includes two through grooves 26 symmetrically opened on the front and rear inner side walls of the through cavity 25. Two moving blocks 27 are symmetrically and slidably connected in the two through grooves 26. The front and rear ends of the hinge shaft 23 are symmetrically and fixedly connected to the side surfaces of the two moving blocks 27 close to each other. The second hinge rod 22 is rotatably sleeved on the hinge shaft 23. The advantage of this setting is that the angle and distance between two adjacent clamping assemblies 1 can be adjusted, so that the fixing device can adapt to more complex in-vehicle installation planes, improving the reliability and practicality of the fixing device.

[0041] Reference Figures 2 - 9 , The fixing mechanism 24 includes two groups of limiting grooves 241 symmetrically opened on the inner top wall and inner bottom wall of the through groove 26. The number of each group of limiting grooves 241 is multiple and evenly distributed along the length direction of the through groove 26. The fixing mechanism 24 further includes an installation cavity opened inside the moving block 27. Two limiting plates 242 are symmetrically and movably inserted into the inner top wall and inner bottom wall of the installation cavity. The side surfaces of the two limiting plates 242 away from each other respectively penetrate through the top wall and bottom wall of the moving block 27 and can be inserted into the inside of the limiting grooves 241. The fixing mechanism 24 further includes a pushing unit 243. The pushing unit 243 is used to push the two limiting plates 242 into the corresponding limiting grooves 241 respectively. The advantage of this setting is that by pushing the two limiting plates 242 into the two limiting grooves 241 by the pushing unit 243, the moving block 27 can be fixed inside the through groove 26. In this way, the first hinge rod 21 and the second hinge rod 22 connected together can be fixedly rotated and slid, so as to fix the positions of multiple clamping assemblies 1, ensure the stability of the position of the automotive wire harness, and improve the reliability of the fixing device.

[0042] Reference Figures 6 - 9, the driving unit 243 includes two groups of second elastic members 2431 symmetrically and fixedly connected between the adjacent sides of the two limiting plates 242. Two arc-shaped bayonets 2421 are symmetrically formed on the adjacent sides of the two limiting plates 242. The driving unit 243 further includes a third elastic member 2432 fixedly connected to the inner side wall of the installation cavity. The other end of the third elastic member 2432 is fixedly connected with a push rod 2433. A frustum head is provided at one end of the push rod 2433 close to the third elastic member 2432. The frustum head is movably inserted between the two bayonets 2421. An annular slot 2434 is formed on the outer side surface of the push rod 2433. The two bayonets 2421 on the two limiting plates 242 can be respectively movably inserted into the two annular slots 2434. Two planar cavities 2435 are symmetrically formed on the outer side surface of the frustum head. The two planar cavities 2435 are parallel to the bottom surface of the limiting plate 242. Both of the two planar cavities 2435 communicate with the annular slot 2434. The distance between the two planar cavities 2435 is less than the minimum distance between the adjacent sides of the two limiting plates 242. The end of the push rod 2433 away from the third elastic member 2432 penetrates through the side wall of the moving block 27 and extends to the outside thereof. The advantage of such a setting is that only by pushing the push rod 2433 towards the direction close to the bayonet 2421 until the two bayonets 2421 are clamped into the annular slot 2434, the two limiting plates 242 can be pushed into the two limiting slots 241 and fixed. In this way, the fixing operation is greatly simplified, so that the installation speed of the fixing device can be improved, and the practicability and convenience of the fixing device are improved.

[0043] Reference Figure 8 and Figure 9 , the driving unit 243 further includes a hollow tube 2436 fixedly connected to the side surface of the moving block 27. The hollow tube 2436 is movably sleeved on the outer peripheral surface of the push rod 2433. A rotating tube 2437 is rotatably sleeved on the outer peripheral surface of the hollow tube 2436. A first torsion spring 2438 is fixedly connected between the adjacent sides of the rotating tube 2437 and the moving block 27. Two sliding plates 2439 are symmetrically and fixedly connected to the outer peripheral surface of the push rod 2433. Two rectangular slots 24310 are symmetrically formed on the inner side wall of the rotating tube 2437. The two sliding plates 2439 are symmetrically and slidably connected in the two rectangular slots 24310. The advantage of such a setting is that when the push rod 2433 is driven to rotate by 90 degrees through the rotating tube 2437 so that the two bayonets 2421 are disengaged from the annular slot 2434, the push rod 2433 will rotate back by 90 degrees and reset under the action of the elastic force of the first torsion spring 2438 and the driving of the sliding plates 2439 and the rectangular slots 24310, so that it is not necessary for the staff to manually reset. In this way, the push rod 2433 can be directly pushed to perform the fixing operation again, further simplifying the fixing operation, further improving the installation speed of the fixing device, and effectively improving the practicability and convenience of the fixing device.

[0044] Reference Figures 1 - 5, the inclination of the conical surface of the conical roller 13 is not greater than 45 degrees. The advantage of this setting is that the distance between the conical surface of the conical roller 13 and the top of the clamping roller 14 is within a reasonable range, thus ensuring the limiting clamping effect and the guiding effect.

[0045] Reference Figure 4 and Figure 10 , it further includes a linkage component 4. The linkage component 4 can make the two conical surfaces of the two conical rollers 13 and the outer peripheral surface of the clamping roller 14 approach each other. The advantage of this setting is that the two conical surfaces of the two conical rollers 13 cooperate with the outer peripheral surface of the clamping roller 14 to be able to clamp and limit more firmly, improving the effect of fixing the wire harness and further enhancing the practicability and reliability of the fixing device.

[0046] Reference Figure 4 and Figure 10 , the linkage component 4 includes a square groove 41 opened on the top of the bottom plate 11. A slide bar 42 is fixedly connected between the front and rear inner side walls of the square groove 41. Two rectangular blocks 43 are symmetrically and movably sleeved on the slide bar 42. Two rotating rods 44 are symmetrically hinged on the tops of the two rectangular blocks 43. The tops of the two rotating rods 44 are hinged to the same lifting plate 45. The clamping roller 14 is fixedly connected to the top of the lifting plate 45. The linkage component 4 further includes two driving rods 46 symmetrically and fixedly connected to the bottoms of the two moving plates 12. The two driving rods 46 respectively abut against the opposite sides of the two rectangular blocks 43. The advantage of this setting is that under the elastic force of the two first elastic members, the two driving rods 46 will push the two rectangular blocks 43 to move towards each other. In this way, the lifting plate 45 can be pushed upward through the two rotating rods 44 to make the clamping roller 14 approach the conical surfaces of the two conical rollers 13, thus automatically completing the approach operation of the clamping roller 14 and the conical surfaces of the two conical rollers 13, further simplifying the clamping operation of the wire harness, ensuring the clamping effect of the wire harness, and improving the practicability and convenience of the fixing device.

[0047] Reference Figure 1 , the thickness of the fixing plate 3 is not less than half of the length of the first hinge rod 21, and the length of the first hinge rod 21 is equal to the length of the second hinge rod 22. The advantage of this setting is that there is enough rotation space between the first hinge rod 21 and the second hinge rod 22, ensuring that the fixing device has enough adaptability to the installation surface in the vehicle and improving the reliability of the fixing device.

[0048] Reference Figures 2 - 5, the clamping assembly 1 further includes two vertical plates 15 symmetrically and fixedly connected to the top of the bottom plate 11. Two groups of round rods 16 are symmetrically and movably inserted on the side surfaces of the two vertical plates 15 close to each other. One ends of the two groups of round rods 16 close to each other are respectively fixedly connected to the two moving plates 12. The first elastic member is fixedly connected between the side surfaces of the vertical plate 15 and the moving plate 12 close to each other. The advantage of such a setting is that it can make the two conical rollers 13 move stably towards each other, so as to ensure that the wire harness can be conveniently and smoothly clamped between the two conical rollers 13 and the wire harness can be clamped.

[0049] Working principle: First, fixedly connect a fixing plate 3 to the vehicle interior mounting surface, then rotate the first hinge rod 21 and the second hinge rod 22 respectively, and then push the moving block 27 to slide on the through groove 26 so that each bottom plate 11 fits the vehicle interior mounting surface.

[0050] Whenever a clamping assembly 1 is positioned, at the same time, push the two push rods 2433 on the clamping assembly 1 towards each other until the two bayonets 2421 are inserted into the annular slot 2434. In this way, the two limiting plates 242 can be pushed away from each other to push the two limiting plates 242 into the two limiting grooves 241 and fixed. In this way, the installation and fixation of the clamping assembly 1 can be completed. Then, after all the clamping assemblies 1 are installed and fixed as above, fixedly connect the remaining fixing plate 3 to the vehicle interior mounting surface. In this way, the fixed installation work of the fixing device can be conveniently completed.

[0051] Subsequently, the wire harness is sequentially clamped between the two conical rollers 13 of each clamping assembly 1. Subsequently, under the elastic force of the two first elastic members, the two driving rods 46 will push the two rectangular blocks 43 to move towards each other. In this way, the lifting plate 45 can be pushed upward by the two rotating rods 44 so that the pinch roller 14 approaches the conical surfaces of the two conical rollers 13, thereby automatically completing the approach operation of the pinch roller 14 and the conical surfaces of the two conical rollers 13, enhancing the clamping effect on the wire harness.

[0052] When there are multiple wire harnesses, multiple such fixing devices can be used to fix the wire harnesses.

[0053] When the wire harness needs to be adjusted, only need to find the corresponding wire harness and pull it to adjust the position of the wire harness. Since the conical roller 13 and the pinch roller 14 can both rotate, the wire harness can be directly pulled to move.

[0054] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
