Description

Technical Field

[0001] This utility model relates to the field of slide rail technology, and in particular to a slide rail structure. Background Technology

[0002] Many car seats are equipped with electric sliding rails at the bottom, which allow the car seat to slide back and forth inside the car to adjust its position.

[0003] Electric sliding rails mainly consist of a lower rail assembly and an upper rail assembly. The lower rail is fixed to the vehicle body, while the upper rail slidably rests on the lower rail. The seat assembly is mounted on the upper rail and slides along with it. Because the lower rail is relatively long and has an upward-facing cavity, the upper rail cannot completely cover it. Foreign objects can easily enter the cavity of the lower rail through the opening, affecting the sliding performance of the electric sliding rail, causing noise, reducing seat comfort, and in severe cases, potentially leading to jamming or malfunction. The open lower rail also poses safety hazards, such as high heels slipping and falling, or children's fingers getting stuck and causing injury. Utility Model Content

[0004] In view of the above-mentioned shortcomings of the existing technology, the technical problem to be solved by this utility model is to propose a slide rail structure that can prevent foreign objects from entering and has good safety performance.

[0005] The technical solution adopted by this utility model to solve its technical problem is to propose a slide rail structure, including:

[0006] The lower rail has an upward opening along its own length;

[0007] The upper rail module is disposed on the lower rail and can slide along the opening;

[0008] A wire harness module, including wires, is connected to the upper rail module;

[0009] When the upper rail module slides along the opening from one end of the lower rail to the other end of the lower rail, it can drive the wire harness module to block the opening.

[0010] Furthermore, the wire harness module also includes a cable chain, the wire is disposed on the cable chain, and the cable chain is connected to the upper rail module;

[0011] When the upper rail module slides along the opening, it drags the cable chain, which then blocks the opening.

[0012] Furthermore, the cable chain has a cable routing channel along its length, and the wire passes through the cable routing channel.

[0013] Furthermore, the cable chain includes multiple links connected in sequence, and each link has a hollow cavity. The hollow cavities of the multiple links are connected in sequence to form the cable routing channel or a part of the cable routing channel.

[0014] Furthermore, the width of the cable chain is greater than the width of the opening.

[0015] Furthermore, the lower rail is provided with a first stop and a second stop at intervals along its length direction, and the first stop and the second stop extend from the lower rail toward the opening respectively;

[0016] The cable chain is positioned below the first and second stops. When the upper rail module drags the cable chain along the opening, the cable chain moves against the first and second stops. The first and second stops can restrict the cable chain from disengaging from the opening onto the lower rail.

[0017] Furthermore, the length of the cable chain is greater than the maximum stroke of the upper rail module on the lower rail.

[0018] Furthermore, the lower rail is provided with a guide at its end, and the drag chain passes through the guide;

[0019] When the upper rail module slides from one end of the lower rail to the other end of the lower rail, the guide member can provide guidance for the drag chain drive.

[0020] Furthermore, each end of the conductor is provided with a conductive connector, one of the conductive connectors extending out of one end of the cable chain and the other conductive connector extending out of the other end of the cable chain.

[0021] Furthermore, each end of the upper rail module is connected to a wire harness module;

[0022] As the upper rail module slides back and forth along the opening on the lower rail, the upper rail module and the two wire harness modules always block the opening.

[0023] Compared with the prior art, the present invention has at least the following beneficial effects:

[0024] In this invention, the wire harness module is connected to the upper rail module. When the upper rail module slides along the opening from one end of the lower rail to the other, it can cause the wire harness module to block the opening of the lower rail. In addition to its conductive function, the wire harness module can also block the opening of the lower rail, which can effectively prevent foreign objects from entering the lower rail through the opening and affecting the normal operation of the slide rail. This ensures the safety of the slide rail, and also has a high aesthetic appeal. The overall structure is simple and easy to assemble.

[0025] In this invention, the wire harness module includes wires and a cable chain. The wires are arranged within the cable chain, which provides protection for the wires and also seals the opening at the lower rail, ensuring good safety. The cable chain comprises multiple links connected by their hollow cavities, allowing the wires to run without requiring additional processing. Furthermore, the width of the cable chain is greater than the width of the opening. The cable chain is positioned below and against the first and second retaining edges, preventing it from detaching from the lower rail at the opening and preventing it from being stepped on, thus ensuring structural stability. The first and second retaining edges also provide support for the cable chain.

[0026] In another embodiment of this utility model, a wire harness module is connected to each end of the upper rail module, so that when the upper rail module slides back and forth along the opening at both ends of the lower rail, the upper rail module and the two wire harness modules always block the opening, ensuring that the opening is always in a blocked state.

[0043] Example 1:

[0044] like Figures 1-5As shown, a slide rail structure in this embodiment mainly includes: a lower rail 1, an upper rail module 2, and a wiring harness module 3. The lower rail 1 is mounted on the vehicle body during use. The upper rail module 2 is slidably mounted on the lower rail 1. The wiring harness module 3 facilitates the external power supply for the slide rail; that is, the slide rail in this embodiment is configured as an electric slide rail. The lower rail 1 has an upward-facing opening 100 along its length. The upper rail module 2 is mounted on the lower rail 1 and can slide along the opening 100. The wiring harness module 3 includes a wire 30 and is connected to the upper rail module 2. When the upper rail module 2 slides along the opening 100 from one end of the lower rail 1 to the other end, it can drive the wiring harness module 3, causing the wiring harness module 3 to block the opening 100.

[0045] It should be noted that when the electric sliding rail is installed at the bottom of the car seat, the seat assembly is mounted on the upper rail module 2. When the upper rail module 2 slides along the lower rail 1, it drives the seat assembly to slide, adjusting the fore-and-aft position of the seat assembly inside the vehicle. Generally, when the upper rail module 2 slides along the lower rail 1 from the rear end to the front end, the opening 100 on the lower rail 1 is easily exposed. Foreign objects can then enter the cavity of the lower rail 1 from the rear side of the seat assembly through the opening 100. Furthermore, high heels from rear passengers or children's fingers can easily enter the cavity of the lower rail 1 through the opening 100. However, when the upper rail module 2 slides from the front end to the rear end of the lower rail 1, the seat assembly is generally positioned above the lower rail 1, making it less likely for foreign objects, high heels from passengers, or children's fingers to enter the cavity of the lower rail 1. In this embodiment, when the upper rail module 2 moves along the opening 100 from the rear end of the lower rail 1 to the front end of the lower rail 1, it is necessary to ensure that the wire harness module 3 can block the opening 100.

[0046] In actual use, the wiring harness module 3 is connected to the upper rail module 2. When the upper rail module 2 slides along the opening 100 from one end (i.e., the rear end) of the lower rail 1 to the other end (i.e., the front end), it can drive the wiring harness module 3 to block the opening 100 of the lower rail 1. In addition to its conductive function, the wiring harness module 3 can also block the opening 100 of the lower rail 1, which can effectively prevent foreign objects from entering the lower rail 1 through the opening 100 and affecting the normal operation of the slide rail, ensuring the safety of the slide rail. Furthermore, passengers cannot see the opening 100 of the lower rail 1, which is aesthetically pleasing. The overall structure is simple and easy to assemble.

[0047] Specifically, in this embodiment, the wire harness module 3 includes not only wires 30, but also a cable chain 31. The wires 30 are disposed on the cable chain 31. Specifically, the number of wires 30 can be one or more, and they are disposed on the cable chain 31. Preferably, in this embodiment, the wires 30 are threaded through the cable chain 31, and the cable chain 31 can provide protection for the wires 30.

[0048] The cable chain 31 is connected to the upper rail module 2. When the upper rail module 2 slides along the opening 100, the cable chain 31 is dragged, which can block the opening 100. That is, the wire harness module 3 blocks the opening 100 of the lower rail 1 through the cable chain 31, and the wire 30 is in the cable chain 31 and moves with the movement of the cable chain 31.

[0049] Understandably, the cable chain 31 of the wiring harness module 3 in this embodiment is also commonly referred to as an engineering plastic cable chain 31, a tank chain, or a cable protection chain. Its main function is to protect and guide cables, oil pipes, air pipes, and other pipelines on moving parts. It generally has the characteristics of being lightweight, wear-resistant, corrosion-resistant, having low operating noise, and relatively low cost.

[0050] Furthermore, in this embodiment, the cable chain 31 of the wire harness module 3 is configured as a fully enclosed cable chain 31, wherein the cable chain 31 has a wiring channel 310 along its length, and the wire 30 passes through the wiring channel 310. Specifically, the cable chain 31 includes multiple links 311 connected in sequence, adjacent links 311 are rotatably connected to each other, and each link 311 has a hollow cavity 311A. The hollow cavities 311A ​​of the multiple links 311 are connected in sequence to form the wiring channel 310 or a part of the wiring channel 310. Sometimes, a connector is provided at the end of the cable chain 31 as needed. The connector also needs to be hollow so that the hollow cavities 311A ​​of the multiple links 311 are connected to the connector to jointly form the wiring channel 310. When no joint is provided at the end of the cable chain 31, the cable chain 31 is formed by multiple links 311 that are rotatably connected in sequence. In this case, the hollow cavity 311A ​​formed by the multiple links 311 connected in sequence forms the cable routing channel 310. The wire 30 is placed in the cable routing channel 310, and the cable chain 31 can provide good protection for the wire 30.

[0051] Furthermore, in this embodiment, the width of the cable chain 31 is greater than the width of the opening 100, ensuring that the cable chain 31 will not detach from the lower rail 1 at the opening 100, thus protecting structural stability. Specifically, the lower rail 1 is provided with a first stop 11 and a second stop 12 spaced apart along its length. The first stop 11 and the second stop 12 extend from the lower rail 1 toward the opening 100, respectively. The first stop 11 extends from one side of the opening 100, and the second stop 12 extends from the other side of the opening 100. The cable chain 31 is positioned below the first stop 11 and the second stop 12. When the upper rail module 2 drags the cable chain 31 along the opening 100, the cable chain 31 moves against the first stop 11 and the second stop 12, thus preventing the cable chain 31 from detaching from the lower rail 1 at the opening 100. Furthermore, the first stop 11 and the second stop 12 can prevent the cable chain 31 from being stepped on, ensuring structural stability. The first stop 11 and the second stop 12 can provide stable support for the cable chain 31.

[0052] In order to ensure that the drag chain 31 is fully covered throughout its travel, in this embodiment, the length of the drag chain 31 is greater than the maximum travel of the upper rail module 2 on the lower rail 1, which also ensures that the setting of the drag chain 31 will not affect the sliding travel of the upper rail module 2 on the lower rail 1.

[0053] Preferably, a guide member 13 is provided at the end of the lower rail 1, and the cable chain 31 passes through the guide member 13. In actual use, when the upper rail module 2 slides from one end of the lower rail 1 to the other end, the guide member 13 can provide guidance for the transmission of the cable chain 31, that is, the guide member 13 can ensure the transmission direction of the cable chain 31, ensuring smooth and reliable movement.

[0054] In practical use, the wiring harness module 3 of this embodiment includes a wire 30 and a cable chain 31. The wire 30 is arranged in the cable chain 31. The cable chain 31 can protect the wire 30 and also seal the opening 100 of the lower rail 1, ensuring good safety performance. The cable chain 31 includes multiple links 311, which are connected by the hollow cavities 311A ​​of the multiple links 311 for the wire 30 to run, without the need for additional processing of the cable chain 31. Furthermore, the width of the cable chain 31 is greater than the width of the opening 100. The cable chain 31 is located below the first stop 11 and the second stop 12, and moves against the first stop 11 and the second stop 12. The first stop 11 and the second stop 12 can prevent the cable chain 31 from detaching from the lower rail 1 at the opening 100 and can prevent the cable chain 31 from being stepped on, ensuring structural stability. The first stop 11 and the second stop 12 can provide support for the cable chain 31.

[0055] Optionally, each end of the wire 30 is provided with a conductive connector 301. One conductive connector 301 extends from one end of the cable chain 31, and the other conductive connector 301 extends from the other end of the cable chain 31. One conductive connector 301 can be connected to a power source for power supply, and the other conductive connector 301 can be connected to a drive mechanism on the electric slide rail, such as, but not limited to, a lead screw motor, to drive the upper rail module 2 to slide along the lower rail 1. The main structure of the lower rail 1 is generally made of metal, and the overall structural strength needs to be ensured. For aesthetic purposes, it is understandable that decorative strips 14 can also be configured on the lower rail 1 to ensure aesthetics. The decorative strips 14 are arranged along both sides of the opening 100. To ensure neatness, a receiving box 15 is provided on the lower rail 1 and is detachably and fixedly connected to it. The cable chain 31 is movably disposed in the receiving box 15.

[0056] Example 2:

[0057] like Figures 6-7 As shown, in this embodiment, the upper rail module 2 is connected to a wire harness module 3 at each end; during use, when the upper rail module 2 slides back and forth along the opening 100 on the lower rail 1, the upper rail module 2 and the two wire harness modules 3 always block the opening 100.

[0058] It should be explained that, unlike Embodiment 1, in this embodiment, a wire harness module 3 is connected to both ends of the upper rail module 2, for a total of two wire harness blocks. In Embodiment 1, only one wire harness module 3 is connected to the rear end of the upper rail module 2. That is, Embodiment 1 has only one wire harness module 3, while this embodiment has two wire harness modules 3.

[0059] In this embodiment, a wire harness module 3 is connected to each end of the upper rail module 2, so that when the upper rail module 2 slides back and forth along the opening 100 at both ends of the lower rail 1, the upper rail module 2 and the two wire harness modules 3 always block the opening 100 of the lower rail 1, ensuring that the opening 100 of the lower rail 1 is always blocked.

[0060] In this solution, the wire harness module 3 of the slide rail structure not only serves to conduct electricity, but also seals the opening 100 of the lower rail 1, which can effectively prevent foreign objects from entering the lower rail 1 through the opening 100 and affecting the normal operation of the slide rail, ensuring the safety of the slide rail, and also having a high aesthetic appeal. The overall structure is simple and easy to assemble.
