Description

Technical Field

[0001] The present application relates to the field of automotive parts, and in particular to a low-height automotive seat rail assembly. Background Art

[0002] In existing technology, automotive seat track assemblies, as key components of seat adjustment systems, are widely used in both traditional fuel-powered and new energy vehicles. The primary function of seat track assemblies is to support smooth seat movement, allowing the driver and passenger to adjust the seat's fore-aft position as desired. Traditional seat track designs generally achieve an ideal balance between structural strength and safety, but they still have limitations in terms of seat height adjustment and interior space utilization.

[0003] With the development of new energy vehicles, the size and weight of battery systems have become significant factors influencing vehicle design. New energy vehicles typically place batteries beneath the chassis. This design creates a higher floor area, preventing the seats from being positioned as low as in traditional fuel-powered vehicles. This in turn impacts ride comfort, interior space, and visibility. Due to chassis height constraints, the seats cannot be lowered further while ensuring maximum comfort and safety. This results in limited interior space, cramped headroom for passengers, especially those in the rear, and a poor riding experience.

[0004] The shortcomings of existing technologies primarily lie in the fact that the design of seat rail assemblies fails to fully account for the unique needs of new energy vehicles, particularly regarding seat height control. Existing seat rails are generally universal, suitable for both fuel-powered vehicles and some new energy vehicles, and are not specifically optimized for the chassis battery layout of new energy vehicles. This results in a thicker overall seat rail assembly, making it difficult to optimize chassis and interior space, and unable to effectively lower seat height for improved ride comfort. More specifically, conventional seat rails are often designed with a fixed height, lacking the ability to be adjusted flexibly, making them difficult to adapt to the low seat design requirements of new energy vehicles.

[0005] Therefore, it is of great significance to develop a novel low-height automobile seat rail assembly. Utility Model Content

[0006] The purpose of this application is to overcome at least one of the shortcomings of the prior art and to provide a low-height automobile seat rail assembly that can reduce the overall height of the seat while ensuring the comfort, safety and adjustment function of the seat, thereby improving the space utilization efficiency in the car and improving the riding experience, especially in the growing market of new energy vehicles.

[0007] To achieve the above-mentioned purpose, the present application discloses a low-height automobile seat guide rail assembly, which includes a guide rail, a slider installed in the guide rail and capable of sliding linearly along the guide rail, wherein the guide rail is in a concave shape and has a convex guide groove inside; the upper end of the guide groove is open; the guide groove has an inner bottom surface for main sliding support, located on both sides of the inner bottom surface for sliding guide and auxiliary support of two opposite side guide positions; the slider is in a convex shape, partially extending upward from the opening of the guide groove, having an outer bottom surface cooperating with the inner bottom surface and side guide blocks for extending from both sides and extending into the side guide positions; the center of the slider is concave to form a central socket with a screw hole, and correspondingly, the inner bottom surface of the guide rail is provided with a working window for the slider to be connected and cooperated with the external automobile seat bracket through the screw hole.

[0008] In some embodiments, in order to further facilitate the connection and fixation with the car seat, the slider is provided with a socket and a tongue for positioning and guiding.

[0009] In some embodiments, in order to further improve the structural strength of the guide groove in the vertical direction, a C-shaped rib for reinforcing the guide rail is provided on the side of the guide rail.

[0010] In some embodiments, the front end and the rear end of the slider sliding along the guide rail are shovel-shaped structures to prevent foreign objects in the guide groove of the guide rail from getting stuck in the slider.

[0011] In some embodiments, the center socket of the relief block has a countersunk design to prevent the protruding screw from interfering with the inner bottom surface of the guide rail.

[0012] 1. By optimizing the cross-sectional structural design of the guide rail assembly and the shape of the slider, this application can reduce the overall height of the guide rail and slider, significantly reduce the installation height of the seat, and minimize the space occupied by the guide rail assembly, thereby effectively improving the interior space utilization efficiency of new energy vehicles, especially providing more headroom for models with limited chassis height and improving ride comfort.

[0013] 2. The C-shaped ribs on the sides of the guide rails effectively increase the vertical structural strength of the guide rails, preventing deformation due to load or long-term use, further enhancing the stability and service life of the seat guide rail assembly, while ensuring that safety and reliability requirements are met while reducing the height.

[0014] 3. The slider is designed as a convex-shaped structure, which cooperates with the bottom surface of the guide groove and the side guides to achieve high-precision sliding support and guidance. At the same time, the front and rear end design of the shovel-like structure effectively prevents foreign objects from getting stuck in the guide groove, improving the smoothness of sliding and further optimizing the seat adjustment experience.

[0015] 4. The concave screw hole design in the center of the slider and the setting of the positioning guide socket and tongue make the connection between the guide rail assembly and the car seat bracket more convenient. At the same time, it enhances the modular adaptability of the assembly, which can flexibly meet the installation requirements of different models for seat rails, further improving applicability and assembly efficiency.

[0028] Refer to the attached Figure 1-6 This embodiment discloses a low-profile automotive seat rail assembly, comprising a rail 1 and a slider 2. While ensuring seat comfort and adjustability, this assembly significantly reduces seat installation height and improves interior vehicle space utilization through optimized structural design. To more clearly illustrate the technical solution of this embodiment, the following details the overall structure, the specific design of each component, its operating principle, and its operational steps.

[0029] The guide rail 1 is a concave-shaped structure, made of high-strength steel through a cold stamping process, and its surface is galvanized to enhance its corrosion resistance. A convex-shaped guide groove 3 is formed inside the guide rail 1. The upper end of the guide groove 3 is open to accommodate the slider 2 and allow part of the structure of the slider 2 to extend out of the guide rail 1 to connect to the seat bracket. The inner bottom surface 7 of the guide groove 3 is precisely polished, and its surface roughness is controlled within an appropriate range, which can provide a smooth sliding contact surface and ensure sufficient friction to support the movement stability of the slider 2. Symmetrical side guides 4 are provided on both sides of the guide groove 3. The side guides 4 are rectangular groove structures, which are used to embed the side guide blocks 9 of the slider 2 to achieve lateral limitation and precise guidance of the slider 2, preventing the slider 2 from swaying sideways during sliding.

[0030] To enhance the flexural rigidity of the guide rail 1, C-shaped ribs 11 are designed on both sides. Manufactured using integrated stamping technology, these ribs enhance the vertical structural strength of the guide rail 1, enabling it to withstand the static and dynamic loads of the seat and passengers. The overall rigidity of the guide rail 1 effectively reduces deformation during sudden braking or cornering, thereby maintaining the stability and reliability of the seat adjustment function.

[0031] Slider 2 is a convex-shaped structure made of high-strength alloy steel. It is precision-forged and surface-hardened with a wear-resistant coating to enhance its hardness and service life. The outer bottom surface 8 of slider 2 slides in contact with the inner bottom surface 7 of guide rail 1, serving as the primary support contact surface. The interaction between the two ensures smooth sliding of slider 2 within guide rail 1. Side guide blocks 9 are provided on either side of slider 2. These are elongated, raised structures whose dimensions are precisely calculated to fit the side guides 4 of guide rail 1, ensuring that the sliding direction of slider 2 is constrained and that no shaking or deviation occurs during sliding.

[0032] The center of the slider 2 is recessed to form a central socket 5, which is internally provided with a screw hole 6 for securing the slider 2 to the seat frame via bolts. The screw hole 6 utilizes a standard thread, with thread accuracy meeting ISO standards, ensuring a secure connection with standard bolts. A work window 10 is provided on the inner bottom surface 7 of the guide rail 1. This window 10 corresponds to the center socket 5 of the slider 2 and provides a passage for bolt installation. This design ensures efficient connection and fixation between the slider 2, guide rail 1, and seat frame, while ensuring easy disassembly and maintenance.

[0033] To further enhance the sliding performance of slider 2, the front and rear ends of slider 2 are designed with shovel-like structures. These shovel-like structures push dust, particles, or other foreign matter that may be in guide groove 3 away from the sliding path as slider 2 moves within guide rail 1, thereby preventing such foreign matter from obstructing the movement of slider 2. This shovel-like design is particularly suitable for addressing the potential for dust accumulation during long-term vehicle use, and its self-cleaning function significantly enhances the reliability and service life of the guide rail assembly.

[0034] The top of the slider 2 is also equipped with a socket 12 and a tongue 13 for positioning and guiding. The socket 12 is a rectangular groove, sized to match the corresponding component on the seat frame, allowing for quick positioning of the slider 2 within the seat frame. The tongue 13 is a long, raised structure designed to provide additional stability when the slider 2 is coupled to the seat frame, preventing shifting or loosening during installation. This design facilitates installation of the guide rail assembly while improving assembly precision and structural stability.

[0035] During operation, when the driver or passenger needs to adjust the seat position, slider 2 slides along guide groove 3 within guide rail 1. The outer bottom surface 8 of slider 2 forms a sliding support contact with the inner bottom surface 7 of guide rail 1, while the side guide blocks 9 engage the side guides 4 to provide lateral guidance and position limiting for slider 2. The movement of slider 2 is driven by a manual or electric adjustment mechanism. The shovel-like structure ensures a clean sliding path during sliding, preventing the slider 2 from being blocked by foreign objects. The range of movement of slider 2 is determined by the length of guide rail 1, ensuring that the fore-and-aft adjustment of the seat can meet the needs of different drivers.

[0036] Through the above-mentioned structural design, this embodiment achieves a significant reduction in the overall height of the guide rail assembly, effectively improving the utilization efficiency of the interior space of new energy vehicles. In actual use, due to the design of the battery arrangement in the chassis of new energy vehicles, the bottom space height is limited, and the traditional guide rail assembly cannot meet the demand for further reduction in seat height. However, this embodiment optimizes the geometric design of the guide rail 1 and the slider 2. Under the premise of ensuring structural strength, the seat installation height is controlled to a lower position, thereby providing passengers with a more comfortable riding experience. At the same time, the reinforcement design of the C-shaped rib 11 prevents the guide rail 1 from being significantly deformed when bearing the gravity of the seat and the passenger, ensuring the long-term reliability of the seat adjustment function. The combined design of the shovel-shaped structure of the slider 2 and the socket 12 and tongue 13 further enhances the practicality and convenience of the guide rail assembly.

[0037] In summary, this embodiment, through its innovative design, solves the existing problem of the rail assembly's inability to further reduce its height, while significantly improving the system's reliability and service life. This embodiment is particularly suitable for the design of new energy vehicle seat systems, providing an efficient and practical technical solution in this field.
