Description

Technical Field

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

[0002] There are a large number of cables inside an automobile, which are used to transmit signals and electricity for the in-vehicle system. In order to save space and prevent cable damage, it is necessary to fix the wire harness on the vehicle frame and cover the wire harness through interior decoration. Generally, the wire harness is bundled and fixed by cable ties, etc., and then the cable ties are fixed on the vehicle frame.

[0003] A Chinese patent with an application date of November 16, 2023 and a publication number of CN117261784B discloses a new energy vehicle wire harness positioning and fixing device; including: a fixing plate, and screw holes are opened at the four corners of the fixing plate; the new energy vehicle wire harness positioning and fixing device further includes: a wire harness fixing unit; in the present invention, a plurality of wire harness fixing units are arranged on the fixing plate, and each wire harness fixing unit can fix the wire harness and can wind the wire harness according to requirements, that is, wind the wire harness separately. According to the different lengths of each wire harness, the winding degree is different, ensuring that each wire harness is in a taut state, and then fixing it, reducing the friction and collision between the wire harness and surrounding objects; thereby reducing the situation of excessive wire harness wear.

[0004] In this technical solution, the wire harness passes through the gap between the fixing blocks at the head and tail and the fixing plate, and passes through the gap between the rotating rod and the limiting rod. By rotating the rotating rod, the wire harness can be wound through the limiting rod to make the wire harness taut. However, generally, there are connection terminals at the ends of the wire harnesses, which are used for connecting between wire harnesses or between the wire harness and the in-vehicle system. The presence of the connection terminals requires a larger gap between the fixing blocks and the fixing plate, resulting in a poor restraint effect on the wire harness. Moreover, when there are many wire harnesses, pre-fixing the wire harnesses by means of interspersion takes a lot of time, affecting the fixing efficiency of the wire harness.

[0016] Compared with the prior art, the present invention provides an automobile wire harness positioning and fixing device, which has the following beneficial effects: 1. For this automobile wire harness positioning and fixing device, the wire harness is clamped into the C-shaped buckle from the opening of the C-shaped buckle for pre-fixing the wire harness. Then, the first knob is rotated to drive the driving shaft to rotate, so as to drive the two connecting plates to approach each other, drive the two first pin shafts to approach each other, drive the outer sliding frame and the first arch frame to move away from each other, and through the transmission of the spacing adjusting member, drive the two fixing plates to move together with the connecting plates, so that the two inner sliding frames move away from each other, so that the inner sliding frames and the outer sliding frames approach each other. The clamping column assemblies fixed on the top of the second support plate and the clamping column assemblies fixed on the top of the first support plate first approach each other to clamp the wire harness. Then, the clamping column assemblies push the wire harness to bend and tighten the wire harness. Thus, the purpose of convenient and fast operation when clamping and fixing the wire harness is achieved. 2. For this automobile wire harness positioning and fixing device, by rotating the second knob, the rotating rod and the convex strip are driven to rotate, so that the external threaded tube rotates, the spacing between the fixing plate and the connecting plate is adjusted, and the inner sliding frame is driven to move, so as to adjust the bending degree of the wire harness. Thus, the purpose of adjusting the bending degree of part of the wire harness can be achieved, so that the bending degrees of the wire harnesses are different to adapt to the different lengths of the wire harnesses. 3. During the movement of the vertical pipe of the automotive wire harness positioning and fixing device, when the sliding column slides along the horizontal part of the guiding groove, the clamping column body approaches the wire harness and pushes the wire harness to bend. At this time, the pressing plate is above the wire harness. Then, the sliding column slides along the inclined part of the guiding groove, the piston rod and the piston plate move downward, and drive the clamping column body to move downward through the spring. When the pressing plate fits on the top of the wire harness, the piston plate and the piston rod can still continue to move downward, and the spring is compressed. Through the elasticity of the spring, the pressing force of the pressing plate on the wire harness is increased, so as to achieve the purpose of elastically squeezing the wire harness on the surface, preventing excessive pressing force from causing damage to the wire harness.

[0017] 4. When the clamping column assembly of the automotive wire harness positioning and fixing device pushes the wire harness to move, the wire harness is bent in a plane. During the process of tightening the wire harness, the redundant wire harness will not occupy too much space. The main body of the present invention is flat, saving the occupied space.

Both the outer sliding frame 301 and the first arch-shaped frame 302 are slidably connected to the guide rod 103. A first support plate 303 is fixedly arranged in an array at the top of the outer sliding frame 301.

The two first rotating arms 304 are hinged through a first pin shaft 305, so that the two first rotating arms 304 are distributed in a V shape. Two first slide rails 306 distributed left and right are fixedly installed on the bottom wall of the mounting base 100. The first pin shaft 305 is slidably connected to the first slide rail 306. The first pin shaft 305 is fixedly installed with a driving assembly 400, and the driving assembly 400 is used to drive the two first pin shafts 305 to approach each other.

Connecting plates 404 are threadedly connected to both ends of the driving shaft 401, and the connecting plates 404 are fixedly installed with the first pin shaft 305. By screwing the first knob 402 to drive the driving shaft 401 to rotate, the two connecting plates 404 can be driven to move towards each other or away from each other. When the two connecting plates 404 move towards each other, the two first pin shafts 305 are driven to approach each other.

[0026] Please refer to Figures 7-8, the inner clamping assembly 500 includes two inner sliding frames 501 which are distributed front and back. The inner sliding frames 501 are slidably connected to the guide rods 103. At the tops of the opposite sides of the two inner sliding frames 501, second support plates 502 are fixedly arranged in an array. One end of the second support plate 502 away from the inner sliding frame 501 is fixedly installed with a clamping column assembly 800.

The second pin shaft 504 is connected to the connecting plate 404 through a spacing adjusting member 600. When the two connecting plates 404 approach each other, the two second pin shafts 504 are driven to approach each other together, thereby driving the two inner sliding frames 501 to move away from each other. Thus, the inner sliding frame 501 and the outer sliding frame 301 will approach each other. The clamping column assemblies 800 installed on the tops of the first support plate 303 and the second support plate 502 first approach each other to clamp the wire harness. After that, the clamping column assemblies 800 on the tops of the first support plate 303 and the second support plate 502 are staggered from each other to push the wire harness to move, so that the wire harness is in a wavy shape and the wire harness is tightened.

[0027] Please refer to Figures 10-11 , the spacing adjusting member 600 includes a rotating rod 601 rotatably connected to the mounting base 100. The rotating rod 601 is located above the driving shaft 401 and the two are parallel to each other. A second knob 602 is fixedly installed at the left end of the rotating rod 601. A rib 603 is fixedly installed on the surface of the rotating rod 601. The rib 603 is parallel to the axis of the rotating rod 601.

The rotating rod 601 and the rib 603 are slidably connected in the rotating wheel 605. Thus, when the rotating rod 601 rotates, the rotating wheel 605 is driven to rotate together through the rib 603. During this process, the rotating wheel 605, the lug 604 and the connecting plate 404 can slide relative to the rotating rod 601.

[0028] On one side of the runner 605 facing the middle of the mounting base 100, an externally threaded tube 606 is fixedly installed, and the externally threaded tube 606 is sleeved outside the rotating rod 601 and the rib 603.

Thus, when the rotating rod 601 rotates to drive the externally threaded tube 606 to rotate, the fixing plate 607 can be driven to move relative to the connecting plate 404, thereby adjusting the spacing between the fixing plate 607 and the connecting plate 404, thereby adjusting the spacing between the inner sliding frame 501 and the outer sliding frame 301, adjusting the bending degree of the wire harness, and adjusting the tension degree of the wire harness.

[0029] Please refer to Figure 9 , the edge clamping assembly 700 includes a second arched frame 701, the second arched frame 701 is slidably connected to the guide rod 103, both ends of the second arched frame 701 extend towards the middle of the mounting base 100, and rack plates 703 are fixedly installed on the opposite sides of the ends of the second arched frame 701 and the first arched frame 302, a gear 704 is meshed between the two rack plates 703, the gear 704 is rotatably connected to the bottom wall of the mounting base 100, and L-shaped plates 702 are fixedly installed in an array on the top of the second arched frame 701, and the L-shaped plates 702 extend towards the middle of the mounting base 100. Thus, when the first arched frame 302 moves outwards, through the transmission of the rack plate 703 and the gear 704, the second arched frame 701 moves inwards, reducing the spacing between the first arched frame 302 and the second arched frame 701, and the clamping post assemblies 800 fixed on the top of the first arched frame 302 and the clamping post assemblies 800 fixed on the top of the L-shaped plates 702 fix the wire harness and push the wire harness to move, making the wire harness in a curved shape.

[0030] Please refer to Figures 12-13 , the clamping post assembly 800 includes a vertical tube 801, two limiting rings 802 are fixedly installed on the circumferential surface of the bottom end of the vertical tube 801, the two limiting rings 802 are distributed up and down, a slider 803 is fixedly installed at the top end of the vertical tube 801, and the slider 803 is slidably connected in the avoidance groove 200, thereby preventing the vertical tube 801 from rotating. The top of the slider 803 is slidably connected through a clamping post body 804, and the bottom end of the clamping post body 804 extends into the vertical tube 801; the cross section of the clamping post body 804 is oval, which can prevent the clamping post body 804 from rotating relative to the slider 803 and the vertical tube 801, and make the arc surface of the clamping post body 804 in contact with the wire harness relatively gentle.

[0031] A pressing plate 805 is fixedly installed at the top of the clamping column body 804. A linear groove 809 is formed through the circumferential surface of the vertical pipe 801. A sliding column 808 is arranged at the bottom of the clamping column body 804. The sliding column 808 is slidably connected in the linear groove 809.

A guiding groove 807 is formed through the clamping side plates 806. A part of the guiding groove 807 is horizontal and the other part is inclined downward. The ratio of the horizontal part to the inclined part can be 2:3. The sliding column 808 is slidably connected in the guiding groove 807. Thus, when the sliding column 808 slides along the horizontal part of the guiding groove 807, the clamping column body 804 approaches the wire harness and pushes the wire harness to bend. After that, when the sliding column 808 slides along the inclined part of the guiding groove 807, the clamping column body 804 continues to push the wire harness to bend. And during this process, the clamping column body 804 and the pressing plate 805 move downward, and the pressing plate 805 presses the wire harness from the top, playing a role in limiting the position.

[0032] A sliding cavity is formed in the lower half of the clamping column body 804. A piston plate 810 is slidably connected in the sliding cavity. A piston rod 811 is fixedly installed at the bottom of the piston plate 810. The piston rod 811 passes through the bottom end of the clamping column body 804. The sliding column 808 is fixedly installed on the piston rod 811. A spring 812 is fixedly installed between the bottom of the piston plate 810 and the bottom wall of the sliding cavity. Due to the elasticity of the spring 812, when the sliding column 808 slides along the horizontal part of the guiding groove 807, the piston plate 810 fits on the top wall of the sliding cavity, and the pressing plate 805 remains away from the wire harness. When the sliding column 808 slides along the inclined part of the guiding groove 807, the piston rod 811 and the piston plate 810 move downward, and drive the clamping column body 804 to move downward through the spring 812. When the pressing plate 805 fits on the top of the wire harness, the piston plate 810 and the piston rod 811 can still continue to move downward, and the spring 812 is compressed. Due to the elasticity of the spring 812, the pressing force of the pressing plate 805 on the wire harness is increased.

[0033] Please refer to Figures 14-15, the rotation inhibiting member 900 includes an arched plate 901 fixedly installed on the top wall of the mounting base 100. Between the bottom ends of the arched plate 901, two cross bars 902 are fixedly installed. Two arc-shaped friction plates 903 are slidably connected to the cross bars 902. The two arc-shaped friction plates 903 are distributed front and back. A rubber sheet is fixedly installed on the outer arc surface of the arc-shaped friction plate 903. A collar 904 is sleeved on the middle part of the rotating rod 601. A rotating column 905 is fixedly installed in the middle part of the drive shaft 401. The arc-shaped friction plates 903 are attached to the circumferential surfaces of the collar 904 and the rotating column 905. Clamping sleeves 906 are fixedly installed on the left and right side walls of the arched plate 901. A U-shaped frame 907 is slidably connected in the clamping sleeve 906. Push rods 908 are hinged at both ends of the U-shaped frame 907. One end of the push rod 908 away from the U-shaped frame 907 is hinged to the middle part of the arc-shaped friction plate 903. A bolt 909 is rotatably connected to the top of the U-shaped frame 907. The bolt 909 passes through the top of the mounting base 100. A threaded hole is opened on the top of the arched plate 901. The arched plate 901 is threadedly connected to the bolt 909 through the threaded hole. By screwing the bolt 909, the U-shaped frame 907 moves downward, thereby pushing the arc-shaped friction plate 903 to slide along the cross bar 902 through the push rod 908, increasing the friction between the arc-shaped friction plate 903 and the collar 904 and the rotating column 905, and preventing the drive shaft 401 and the rotating rod 601 from rotating accidentally.

[0034] When in use, first, the wire harness is clamped into the C-shaped buckle 102 from the opening of the C-shaped buckle 102 to pre-fix the wire harness. Then, rotate the first knob 402 to drive the drive shaft 401 to rotate, thereby driving the two connecting plates 404 to approach each other, driving the two first pin shafts 305 to approach each other, driving the outer sliding frame 301 and the first arched frame 302 to move away from each other, and through the transmission of the spacing adjusting member 600, driving the two fixing plates 607 to move together with the connecting plate 404, so that the two inner sliding frames 501 move away from each other, so that the inner sliding frame 501 approaches the outer sliding frame 301. The clamping column assemblies 800 fixed on the top of the second support plate 502 and the clamping column assemblies 800 fixed on the top of the first support plate 303 first approach each other to clamp the wire harness, and then, the clamping column assemblies 800 push the wire harness to bend to tighten the wire harness. At the same time, when the first arched frame 302 moves outward, cooperating with the transmission of the rack plate 703 and the gear 704, driving the second arched frame 701 to move inward. The clamping column assemblies 800 fixed on the top of the L-shaped plate 702 and the top of the first arched frame 302 also first clamp the wire harness and then push the wire harness into a bent shape. Then, by rotating the second knob 602, driving the rotating rod 601 and the convex strip 603 to rotate, causing the external threaded tube 606 to rotate, adjusting the spacing between the fixing plate 607 and the connecting plate 404, and driving the inner sliding frame 501 to move, thereby adjusting the bending degree of the wire harness. During the movement of the vertical pipe 801, when the sliding column 808 slides along the horizontal portion of the guiding groove 807, the clamping column body 804 approaches the wire harness and pushes the wire harness to bend. At this time, the pressing plate 805 is located above the wire harness. Then, the sliding column 808 slides along the inclined portion of the guiding groove 807, the piston rod 811 and the piston plate 810 move downward, and drive the clamping column body 804 to move downward through the spring 812. When the pressing plate 805 fits against the top of the wire harness, the piston plate 810 and the piston rod 811 can still continue to move downward, and the spring 812 is compressed. Through the elasticity of the spring 812, the pressing force of the pressing plate 805 on the wire harness is increased.
