Description

Technical Field

[0001] This application relates to the field of automotive guide rails, and in particular to an automotive seat slide rail assembly. Background Technology

[0002] As society develops, cars have become an essential tool for every family's travel. The demands for car functions are constantly evolving. This has led to a need for seats to offer a variety of functions, such as rotation, sliding, massage, and ventilation.

[0003] In existing electric sliding seats for automobiles, the battery is usually installed in the vehicle body, and the seat sliding is typically controlled by a motor and lead screw. To meet multiple functions and facilitate seat sliding adjustments, multiple cables need to be laid on the seat rails.

[0004] As the number of wiring harnesses on the seat rails increases, and given that the seats often need to be moved and adjusted, problems such as cable bending, breaking, and knotting are extremely likely to occur. In particular, as the usage time increases, the cables themselves are also prone to aging, making it even easier for safety accidents to occur after the seat is adjusted. Summary of the Invention

[0005] To improve seat safety, this application provides an automotive seat slide rail assembly.

[0006] The automotive seat slide rail assembly provided in this application adopts the following technical solution:

[0007] An automotive seat slide rail assembly includes two parallel track seats. A mounting seat for mounting a seat is slidably disposed on the track seats along the length of the track seats. A socket is provided on the mounting seat. A slider is fixedly connected to the lower part of the mounting seat. A first conductive plate is provided on the inner cavity sidewall of the track seats. A first conductive contact assembly is mounted on the slider. The first conductive contact assembly is electrically connected to the socket and to the first conductive plate. A drive assembly for driving the mounting seat to slide is also provided on the track seats.

[0008] By adopting the above technical solution, when the slider is driven by the drive component to slide on the track seat, it drives the mounting base and the seat fixed on the mounting base to move, thereby realizing the adjustment of the seat. During the sliding process of the slider, in order to ensure the stability of the power supply, the slider drives the first conductive contact assembly to slide in contact with the first conductive plate. The first conductive plate is connected to the external circuit, so that the first conductive contact assembly is energized and then electrically connected to the socket through the wiring harness. The control buttons on the car seat can be electrically connected to the socket through wires. Since the track seat and the slider conduct electricity through sliding, there is no need to lay cables between them, which solves the difficulty of wiring long sliding rails for car seats and improves the safety of seat use.

[0009] Optionally, two first conductive plates are provided, and the two first conductive plates are respectively disposed on the inner side walls of the track seat. The first conductive plate includes a mounting plate and several copper strips embedded in the mounting plate. Several guide grooves are opened on the side of the mounting plate facing the slider, and a groove communicating with the guide groove is opened on the side of the guide groove facing the slider. The copper strips are embedded in the groove.

[0010] By adopting the above technical solution, the number of power lines is increased, and the setting of guide grooves and embedding grooves enhances the stability of the contact between the conductive sheet and the copper strip.

[0011] Optionally, the mounting plate is made of insulating material, and the contact surface between the conductive sheet and the copper strip can be set as a contact portion, wherein the curvature of the contact portion gradually decreases.

[0012] By adopting the above technical solution, the safety of the insulation material is improved. As the curvature gradually decreases, the angle of the conductive sheet can be adjusted according to the actual resistance force during the installation process, ensuring good contact between the conductive sheet and the copper strip.

[0013] Optionally, the copper strip includes a first plate and a second plate integrally formed on the first plate. The first plate and the second plate are set at an angle, and the angle is an obtuse angle. A conductive trench is formed at the connection between the first plate and the second plate.

[0014] By adopting the above technical solution, the conductive sheet is made to contact the conductive groove, ensuring the stability of the conductive sheet as it slides in the conductive groove with the slider.

[0015] Optionally, the first conductive contact assembly is configured as two sets, with the two first conductive contact assemblies located on both sides of the slider, and the two first conductive contact assemblies respectively corresponding to the first conductive plate. The first conductive contact assembly includes a connecting plate installed on one side of the slider and several sets of conductive sheets disposed on the connecting plate. The conductive sheets are arc-shaped when they contact the side wall of the copper strip. The conductive sheets are inserted into the corresponding guide grooves and contact the copper strip. Each set of conductive sheets is electrically connected to the socket through a wire.

[0016] By adopting the above technical solution, more power control circuits are added, making it easier for the seat to achieve more functions.

[0017] Optionally, a support plate is fixed on one side of the slider, and a first conductive contact assembly is mounted on the support plate. A second conductive contact assembly is mounted on the bottom of the support plate. The structure of the second conductive contact assembly is the same as that of the first conductive contact assembly. A second conductive plate is provided below the second conductive contact assembly for cooperation with itself. The structure of the second conductive plate is the same as that of the first conductive plate.

[0018] By adopting the above technical solution, more power lines are added to the original structure, making it easier to integrate more electronic control function modules into the seat.

[0019] Optionally, each of the connecting plates is provided with two sets of conductive plates. A mounting rod for driving the rotation of a single set of conductive plates is rotatably provided on the connecting plate. A worm gear is coaxially fixed to the end of the mounting rod. A worm is rotatably provided on the connecting plate to drive the two worm gears to rotate synchronously in opposite directions. The teeth at both ends of the worm are arranged in opposite directions. The two worm gears are respectively meshed at the two ends of the worm. A first motor is also fixed on the connecting plate. The first motor is coaxially fixedly connected to the worm.

[0020] By adopting the above technical solution, long-term use of the guide rail will cause wear between the conductive sheet and the copper strip, which will lead to poor contact. To address this, the rotation of the shaft of the first motor is controlled so that the worm gear meshes with the two worm wheels on the single connecting plate and rotates synchronously in opposite directions, causing the conductive sheet to rotate. Since the side wall of the conductive sheet is arc-shaped, the arc surface at the far end fits into contact with the copper strip, ensuring good conductive contact.

[0021] Optionally, the drive assembly includes a second motor fixedly mounted on the end of the track seat and a lead screw coaxially fixed on the shaft of the second motor, the lead screw being threadedly connected to the slider.

[0022] By adopting the above technical solution, during the process of driving the slider to move, the rotating shaft of the second motor is controlled by the vehicle control system to rotate synchronously, so that the slider drives the mounting seat to slide on the track seat.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] During the movement of the seat, there is no need to lay power cables between the slider and the track seat. The conductive sheet moves with the slider and makes electrical contact with the first or second conductive plate, thereby achieving the power supply effect and improving the safety of the seat.

Detailed Implementation

[0037] The following is in conjunction with the appendix Figure 1-10 This application will be described in further detail.

[0038] Example 1:

[0039] This application discloses an automotive seat slide rail assembly.

[0040] Reference Figure 1 The car seat slide rail assembly includes a rail base 1, of which two rail bases 1 are provided. In actual use, the two rail bases 1 are arranged in parallel. A mounting seat 2 is slidably mounted on the rail base 1 along its length, and the mounting seat 2 is used to fix the car seat in place.

[0041] Reference Figure 2 In this embodiment, since the track seat 1 is used in a commercial vehicle, its length is relatively long. Therefore, two seats need to be installed on a set of track seats 1 to achieve adjustment of the front and rear rows of seats. The track seat 1 is provided with a drive assembly 7 for driving the mounting seat 2 to slide. The drive assembly 7 includes a second motor 26 and a lead screw 27. In a single track seat 1, there are two lead screws 27, and correspondingly two second motors 26. The second motors 26 are fixed to the ends of the track seat 1 of the mounting seat 2, and the lead screws 27 are rotatably connected to the inner cavity of the track seat 1. The lead screws 27 are coaxially fixedly connected to the rotating shafts of the second motors 26. In a single track seat 1, one lead screw 27 is used to control the sliding of the mounting seat 2 on the front seat, and the other lead screw 27 is used to control the sliding of the mounting seat 2 on the rear seat.

[0042] Reference Figure 2 In this embodiment, the sliding of the seat is controlled by two parallel lead screws 27, which ensures the stability of the seat sliding. At the same time, two second motors 26 with the same rotation speed but different power consumption and shapes and sizes are used to reduce power consumption while ensuring stable seat sliding.

[0043] Reference Figure 3 and Figure 4 A slider 4 is fixedly installed at the bottom of the mounting base 2, and first conductive contact assemblies 6 are installed on both sides of the slider 4. First conductive plates 5 are fixedly installed on both sides of the inner cavity of the track base 1. The first conductive contact assemblies 6 are electrically connected to the first conductive plates 5. A socket 3 is fixedly installed on the mounting base 2, and the socket 3 is electrically connected to the first conductive contact assemblies 6 through a wire harness.

[0044] Reference Figure 4 and Figure 5The first conductive plate 5 includes a mounting plate 8 and copper strips 9 disposed on the mounting plate 8. The mounting plate 8 is made of insulating plastic. The number of copper strips 9 needs to be selected according to the variety of functions of the car seat. Several guide grooves 10 are evenly spaced on the side of the mounting plate 8 facing the slider 4. An embedding groove 11 is formed on the inner wall of the guide groove 10. The embedding groove 11 is connected to the guide groove 10, and the copper strips 9 are embedded in the embedding groove 11.

[0045] Reference Figure 5 To ensure stable contact, the copper strip 9 includes a first plate 14 and a second plate 15, which are integrally formed. The first plate 14 and the second plate 15 are set at an angle, and the angle between them is an obtuse angle. Thus, a conductive groove 16 is formed on the side of the first plate 14 and the second plate 15 facing a conductive contact assembly.

[0046] Reference Figure 4 , Figure 5 and Figure 6 The first conductive contact assembly 6 includes a connecting plate 17 and conductive sheets 18. The connecting plate 17 is fixed to the side wall of the slider 4. Two sets of conductive sheets 18 are provided, and the number of conductive sheets 18 in each set is equal to the number of copper strips 9. By providing two sets of conductive sheets 18, the stability of the contact between the conductive sheets 18 and the copper strips 9 is ensured.

[0047] Reference Figure 5 and Figure 6 One end of the conductive sheet 18 is mounted on the connecting plate 17, and the other end is embedded in the guide groove 10 and located in the conductive trench 16, thereby realizing the electrical connection between the conductive sheet 18 and the copper strip 9. In this embodiment, the conductive sheet 18 can be fixedly mounted on the connecting plate 17 or rotatably mounted on the connecting plate 17. In this embodiment, it is preferred that the conductive sheet 18 is rotatably connected to the connecting plate 17. When the conductive sheet 18 is rotatably connected to the connecting plate 17, a spring 13 is provided between the two sets of conductive sheets 18. The number of springs 13 is equal to the number of copper strips 9. One end of the spring 13 is hooked into one set of conductive sheets 18, and the other end of the spring 13 is hooked into the opposite conductive sheet 18 in the other set.

[0048] Reference Figure 5 and Figure 6 The conductive sheet 18 has an arc-shaped surface facing the conductive groove 16. The part of the conductive sheet 18 that contacts the copper strip 9 is designated as the contact portion 12. The curvature of the contact portion 12 is greatest at its initial end and gradually decreases. In the initial state, the contact point between the conductive sheet 18 and the copper strip 9 is located at the initial end of the contact portion 12. This results in a tighter contact between the conductive sheet 18 and the copper strip 9 when the conductive sheet 18 is rotated. The conductive sheet 18 is connected to the socket 3 via a wire, facilitating the seat's control functions.

[0049] Reference Figure 7 and Figure 8To enable more control functions for the seat, the number of circuits is increased accordingly. A support plate 19 is fixed to one side of the slider 4, and the support plate 19 is arranged parallel to the connecting plate 17. This allows one of the first conductive contact assemblies 6 to be mounted on the support plate 19. A second conductive contact assembly 20 is mounted at the bottom of the support plate 19. The structure of the second conductive contact assembly 20 is the same as that of the first conductive contact assembly 6. Correspondingly, a second conductive plate 21 with the same structure as the first conductive plate 5 is provided below the second conductive contact assembly 20. The conductive sheet 18 in the second conductive contact assembly 20 slides and engages with the second conductive plate 21, and is electrically connected to the copper strip 9 on the second conductive plate 21.

[0050] Example 2:

[0051] The difference between Example 2 and Example 1 is that: (Refer to...) Figure 9 and Figure 10 To further ensure the stability of the sliding conductivity, the angle adjustment of the conductive sheet 18 in this embodiment relies on active adjustment. A mounting rod 22 is rotatably mounted on the connecting plate 17 to drive the synchronous rotation of a single set of conductive sheets 18. One end of the conductive sheet 18 is fixed to the mounting rod 22 on the connecting plate 17, allowing the conductive sheet 18 to rotate on the connecting plate 17. A worm gear 23 is coaxially fixed to the end of the mounting rod 22, resulting in two worm gears 23 on a single connecting plate 17.

[0052] Reference Figure 9 and Figure 10 To achieve synchronous counter-rotation of the two sets of conductive plates 18 and increase the contact force between the conductive plates 18 and the copper strip 9, a worm gear 24 is rotatably mounted on the connecting plate 17. The worm gear 24 is integrally formed by two teeth with opposite directions of rotation. The worm gear 24 meshes with a worm wheel 23. A first motor 25 is fixed on the connecting plate 17, and the shaft of the first motor 25 is coaxially and fixedly connected to the shaft of the worm gear 24. The first motor 25 can be driven by power supplied from the conductive plates 18. When wear is severe, the shaft of the first motor 25 can be rotated by pressing the control button on the seat or the central control key, causing the worm gear 24 to mesh with the worm wheel 23 and rotate. This causes the more distant end of the conductive plate 18 to rotate towards the copper strip 9 until contact is made. This ensures the stability of the conductive contact and conductivity between the conductive plate 18 and the copper strip 9.
