Description

Technical Field

[0001] This utility model relates to the field of automotive seat wiring harness manufacturing technology, specifically a connecting wiring harness for adjusting the fore-and-aft position of an automotive seat. Background Technology

[0002] The automotive industry is an important pillar industry of the national economy. In order to improve the comfort of drivers, car seats generally have fore-and-aft adjustment functions. Currently, many car seats are electrically adjustable. Therefore, it is necessary to connect the electric structure of the car seat to the vehicle's main control system through a wiring harness.

[0003] A search revealed a patent with patent number 202121346860.2, entitled "Utility Model of Connecting Wiring Harness for Fore-and-aft Adjustment of Car Seats." The patent includes a wire with connectors at both ends, namely a first connector and a second connector. The end of the wire connected to the first connector is configured as a spring wire structure. The first connector is used to connect to the car ECU unit, and the second connector is used to connect to the seat button switch.

[0004] Research and analysis revealed that this wiring harness, by designing one end of the wire as a spring wire structure, facilitates the forward and backward movement of the car seat without affecting the wiring harness connection. It allows for seat position adjustment via a button switch to meet the needs of different users, greatly improving the convenience of car seat adjustment. The inclusion of waterproof clips on the wires effectively prevents water from entering the car's ECU unit. This addresses certain safety hazards and the tendency for wires to become tangled in existing electronic wiring harnesses during long-term use. However, some drawbacks remain: the lack of a guide component means that seat adjustment can cause the wiring harness to shift, potentially leading to misalignment; the waterproof clips alone on the surface of the connecting wires offer limited protection; and the connectors are typically clamped to other connecting wires, resulting in lower stability and susceptibility to loosening due to vehicle vibrations. Utility Model Content

[0005] The purpose of this utility model is to provide a connecting harness for adjusting the fore-and-aft position of a car seat, so as to solve the problems mentioned in the background art, such as the harness misalignment during use, poor waterproofing, and easy loosening of the connectors.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a connecting harness for adjusting the fore-and-aft position of an automobile seat, comprising a harness body, the harness body being composed of a spring segment, a connecting segment, a connector end, and a straight segment. The surface of the harness body is provided with a connecting segment, both ends of which are fixed with spring segments. One end of each spring segment is fixed with a straight segment, and one end of each straight segment is fitted with a connector end. A connector wire is provided on one side of the connector end. A guide mechanism is provided inside the spring segment, the guide mechanism including a connecting sleeve, a sleeve, a mounting ear, and an adjusting slide rod. An anti-detachment mechanism is provided between the connector end and the connector wire, the anti-detachment mechanism including an elastic band, a plastic wire clip, a groove, and an elastic hanging rope. A waterproof mechanism is fitted onto the surface of the straight segment, the waterproof mechanism consisting of a waterproof component and an external screw seat.

[0007] Preferably, a sleeve is provided inside the spring segment, and a connecting sleeve is fixed to one end of the sleeve, which is then fitted onto one end of the spring segment.

[0008] Preferably, an adjusting slide rod is slidably provided inside the sleeve, and a mounting ear is fixed at the center of the adjusting slide rod, the mounting ear being located on one side of the connecting section.

[0009] Preferably, an elastic band is adhered to one side of the connector end, and a plastic wire clip is fixed to the surface of the connector wire, with the surface of the plastic wire clip being adhered and fixed to one end of the elastic band.

[0010] Preferably, an elastic hanging rope is glued to the other side of the connector end, and a groove is provided on one side of each plastic wire clip, the groove being engaged with the elastic hanging rope.

[0011] Preferably, the surface of the straight segment is fitted with an external threaded seat, and the interior of the external threaded seat is provided with a waterproof component.

[0012] Preferably, the waterproof component includes an inner threaded cylinder, a rectangular groove, a first sealing airbag, a double-ended piston rod, a second sealing airbag, and an annular groove. The inner threaded cylinder is provided inside the outer threaded seat and is sleeved on the outside of the straight section. The inner threaded cylinder is threadedly engaged with the outer threaded seat.

[0013] Preferably, the inner wall of the inner screw cylinder is adhered with a second sealing airbag, and the inner wall of the outer screw seat is adhered with a first sealing airbag. When the inner screw cylinder rotates into the outer screw seat, the first sealing airbag and the second sealing airbag are tightly fitted to the surface of the straight segment, respectively.

[0014] Preferably, an annular groove is provided at the edge of the inner screw cylinder, the central axis of the annular groove coincides with the central axis of the inner screw cylinder, and the annular groove is connected to the second sealing airbag.

[0015] Preferably, the inner wall of the external screw seat is provided with a rectangular groove along the circumference, the rectangular groove is connected to the first sealing airbag, and a double-headed piston rod is slidably arranged inside the rectangular groove, one end of the double-headed piston rod extends into the interior of the annular groove and slides in cooperation with the annular groove.

[0016] Compared with the prior art, the beneficial effects of this utility model are: the connecting harness for adjusting the front and rear of the car seat not only avoids the phenomenon of spring wire segment deviation during use and improves the waterproof effect of the connecting harness, but also avoids the phenomenon of loosening of the connector end and connector wire during use. With a guiding mechanism, the connecting harness is installed at the corresponding position on one side of the seat by screws and mounting ears. When the seat is adjusted forward and backward, the straight segment moves, stretching the spring segment. At the same time, the straight segment drives the connecting sleeve to move synchronously, causing the sleeve to slide along the adjusting slide rod. Under the action of the sleeve, the spring segment can be guided to prevent it from deviating. When the seat returns to its original position, the spring force of the spring segment drives the straight segment to return to its original position, and the sleeve to return to its original position. This achieves the guiding function of the connecting harness on the spring segment, thereby preventing the spring segment from deviating during use. By incorporating a waterproof mechanism, the mechanism is fitted onto the surface of the straight section during production. At this point, the first and second sealing airbags are not fully inflated and do not contact the straight section, allowing the straight section to quickly pass through them. After the straight section is inserted, the inner screw can be rotated. The screw engages with the outer screw seat, causing the inner screw to rotate downwards. This causes the inner screw to move synchronously with the annular groove. Simultaneously, the double-ended piston rod is guided and limited by the rectangular groove. As the annular groove gradually descends, the double-ended piston rod pushes the groove downwards, inflating the second sealing airbag and ensuring it adheres tightly to the surface of the straight section. Meanwhile, the inner screw continues to descend, pressing the double-ended piston rod downwards along the rectangular groove and inflating the first sealing airbag, ensuring it adheres tightly to the surface of the straight section. This provides efficient waterproofing for the straight section, achieving a highly efficient waterproof function for the connecting harness and improving its waterproof performance during use. By incorporating an anti-detachment mechanism, the connector end is plugged into the connector wire for electrical connection. Then, pulling the plastic wire clip stretches the elastic band, securing the clip to the surface of the elastic band. Next, pulling the elastic hanging rope loops it over the groove on the surface of the plastic wire clip, thus securing the clip and reinforcing the connector end and connector wire. This prevents the connector end and connector wire from loosening due to vehicle vibration, achieving the function of reinforcing the connector end and connector wire in the wiring harness and preventing them from loosening during use.

At the same time, in the description of the present utility model, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present utility model.

[0020] This utility model provides a structure for a connecting harness used for adjusting the fore-and-aft position of a car seat, as shown in the example below. Figure 1 and Figure 2 As shown, the harness includes a wire harness body 1, which is composed of a spring wire segment 11, a connecting segment 12, a connector end 13, and a straight segment 14. The surface of the wire harness body 1 is provided with a connecting segment 12, and both ends of the connecting segment 12 are fixed with spring wire segments 11. One end of the spring wire segment 11 is fixed with a straight segment 14, and one end of the straight segment 14 is equipped with a connector end 13. A connector wire 2 is provided on one side of the connector end 13.

[0021] Furthermore, such as Figure 2As shown, a guide mechanism 3 is provided inside the spring segment 11. The guide mechanism 3 includes a connecting sleeve 31, a sleeve 32, a mounting ear 33, and an adjusting slide rod 34. The sleeve 32 is provided inside the spring segment 11. The connecting sleeve 31 is fixed to one end of the sleeve 32. The connecting sleeve 31 is fitted onto one end of the spring segment 11. The adjusting slide rod 34 is slidably provided inside the sleeve 32. The mounting ear 33 is fixed at the center of the adjusting slide rod 34 and is located on one side of the connecting segment 12.

[0022] In use, the connecting harness is installed at the corresponding position on one side of the seat by screws and mounting ears 33. When the seat is adjusted forward and backward, the straight segment 14 moves, stretching the spring segment 11. At the same time, the straight segment 14 drives the connecting sleeve 31 to move synchronously, causing the sleeve 32 to slide along the adjusting slide rod 34. Under the action of the sleeve 32, the spring segment 11 can be guided to prevent it from deviating. When the seat is reset, the spring force of the spring segment 11 drives the straight segment 14 to reset, and the sleeve 32 to reset, thus realizing the guiding function of the connecting harness on the spring segment 11.

[0023] Furthermore, such as Figure 4 As shown, an anti-detachment mechanism 4 is provided between the connector end 13 and the connector line 2. The anti-detachment mechanism 4 includes an elastic band 41, a plastic wire clip 42, a groove 43, and an elastic hanging rope 44. An elastic band 41 is glued to one side of the connector end 13, and a plastic wire clip 42 is clipped onto the surface of the connector line 2. The surface of the plastic wire clip 42 is glued and fixed to one end of the elastic band 41. An elastic hanging rope 44 is glued to the other side of the connector end 13. A groove 43 is provided on one side of the plastic wire clip 42, and the groove 43 and the elastic hanging rope 44 are hooked and cooperate with each other.

[0024] In use, connect connector 13 to connector wire 2 for electrical connection. Then pull plastic wire clip 42 to stretch elastic band 41. Then clip plastic wire clip 42 onto the surface of elastic band 41 to fix plastic wire clip 42. Then pull elastic hanging rope 44 to put elastic hanging rope 44 into the groove 43 on the surface of plastic wire clip 42. At this time, elastic hanging rope 44 will fix plastic wire clip 42, thereby reinforcing connector 13 and connector wire 2 and preventing connector 13 and connector wire 2 from loosening due to vehicle vibration, so as to realize the function of reinforcing connector 13 and connector wire 2 of the connecting harness.

[0025] Furthermore, such as Figure 3As shown, a waterproof mechanism 5 is fitted onto the surface of the straight segment 14. The waterproof mechanism 5 consists of a waterproof component 51 and an external threaded seat 52. The external threaded seat 52 is fitted onto the surface of the straight segment 14, and the waterproof component 51 is disposed inside the external threaded seat 52. The waterproof component 51 includes an inner threaded cylinder 511, a rectangular groove 512, a first sealing airbag 513, a double-ended piston rod 514, a second sealing airbag 515, and an annular groove 516. The inner threaded cylinder 511 is disposed inside the external threaded seat 52 and is fitted onto the outside of the straight segment 14. The inner threaded cylinder 511 is threaded into the external threaded seat 52. The second sealing airbag 515 is adhered to the inner wall of the inner threaded cylinder 511, and the first sealing airbag 515 is adhered to the inner wall of the external threaded seat 52. When the inner screw cylinder 511 rotates into the outer screw seat 52, the first sealing airbag 513 and the second sealing airbag 515 are tightly fitted with the surface of the straight section 14 respectively. An annular groove 516 is provided at the edge of the inner screw cylinder 511. The central axis of the annular groove 516 coincides with the central axis of the inner screw cylinder 511. The annular groove 516 is connected to the second sealing airbag 515. A rectangular groove 512 is provided circumferentially on the inner wall of the outer screw seat 52. The rectangular groove 512 is connected to the first sealing airbag 513. A double-headed piston rod 514 is slidably arranged inside the rectangular groove 512. One end of the double-headed piston rod 514 extends into the interior of the annular groove 516 and slides with the annular groove 516.

[0026] During use, the waterproof mechanism 5 is fitted onto the surface of the straight section 14 during production. At this time, the gas inside the first sealing airbag 513 and the second sealing airbag 515 is insufficient and does not contact the straight section 14, allowing the straight section 14 to quickly pass through the first sealing airbag 513 and the second sealing airbag 515. After the straight section 14 has been inserted, the inner screw cylinder 511 can be rotated. Under the threaded engagement between the inner screw cylinder 511 and the outer screw seat 52, the inner screw cylinder 511 rotates downward, causing the inner screw cylinder 511 to drive the annular groove 516 to move synchronously. At this time, the double-headed piston rod 514 is in the rectangular groove 512. Under the action of the guide limit, the double-headed piston rod 514 pushes the inside of the annular groove 516 downward as the annular groove 516 gradually moves downward, inflating the second sealing airbag 515 so that the second sealing airbag 515 is in close contact with the surface of the straight section 14. At the same time, the inner screw cylinder 511 continues to move downward and squeezes the double-headed piston rod 514 to slide downward along the rectangular groove 512, inflating the first sealing airbag 513 so that the first sealing airbag 513 is in close contact with the surface of the straight section 14, thus providing efficient waterproofing for the straight section 14 and achieving the efficient waterproofing function of the connecting wire harness.

[0027] Working principle: During use, the waterproof mechanism 5 is first fitted onto the surface of the straight section 14 during production. At this time, the gas inside the first sealing airbag 513 and the second sealing airbag 515 is insufficient and they do not contact the straight section 14, allowing the straight section 14 to quickly pass through the first sealing airbag 513 and the second sealing airbag 515. After the straight section 14 has been inserted, the inner screw cylinder 511 can be rotated. Under the threaded engagement between the inner screw cylinder 511 and the outer screw seat 52, the inner screw cylinder 511 rotates downward, causing the inner screw cylinder 511 to drive the annular groove 516 to move synchronously. At this time, the double-headed piston rod 514 moves under the action of the rectangular groove 512. The guide limit is activated. Simultaneously, the double-headed piston rod 514 pushes the annular groove 516 downwards, inflating the second sealing airbag 515 and making it tightly adhere to the surface of the straight section 14. At the same time, the inner screw cylinder 511 continues to press the double-headed piston rod 514 downwards along the rectangular groove 512, inflating the first sealing airbag 513 and making it tightly adhere to the surface of the straight section 14, thus providing efficient waterproofing for the straight section 14. This achieves efficient waterproofing of the connecting wire harness, thereby improving the waterproofing effect of the connecting wire harness during use.

[0028] In use, the connecting harness is installed at the corresponding position on one side of the seat by screws and mounting ears 33. When the seat is adjusted forward and backward, the straight segment 14 moves, stretching the spring segment 11. At the same time, the straight segment 14 drives the connecting sleeve 31 to move synchronously, causing the sleeve 32 to slide along the adjusting slide rod 34. Under the action of the sleeve 32, the spring segment 11 can be guided to avoid deviation. When the seat is reset, the spring force of the spring segment 11 drives the straight segment 14 to reset, and the sleeve 32 to reset, so as to realize the guiding function of the connecting harness on the spring segment 11, thereby avoiding the phenomenon of the spring segment 11 deviating during use.

[0029] Then, connect connector 13 to connector wire 2 for electrical connection. Next, pull the plastic wire clip 42 to stretch the elastic band 41. Then, clip the plastic wire clip 42 onto the surface of the elastic band 41 to fix the plastic wire clip 42. Then, pull the elastic hanging rope 44 to put the elastic hanging rope 44 into the groove 43 on the surface of the plastic wire clip 42. At this time, the elastic hanging rope 44 secures the plastic wire clip 42, thereby reinforcing connector 13 and connector wire 2 and preventing connector 13 and connector wire 2 from loosening due to vehicle vibration. This achieves the function of reinforcing connector 13 and connector wire 2 of the connecting harness, thereby preventing connector 13 and connector wire 2 from loosening during use of the connecting harness. Finally, the use of the connecting harness is completed.
