Description

Technical Field

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

[0002] As a core component of automotive interiors, car seats are crucial devices that provide support and a comfortable driving experience for passengers. Against the backdrop of rapid development in the automotive industry, and with the increasing frequency of travel and higher demands for driving and riding quality, seats have evolved from simple functional components into important parts integrating safety, comfort, and functionality. They are widely used in various passenger cars and commercial vehicles, directly impacting the user's travel experience.

[0003] Existing seat rail designs are relatively simple, mostly employing a unidirectional rail layout. This results in limited usage scenarios, with most rails extending only longitudinally along the vehicle body, supporting only fore-and-aft seat movement. They fail to consider users' needs for lateral space adjustment in different scenarios, severely restricting seat space utilization and functional expansion. This prevents the full release of interior space potential and makes it difficult to meet increasingly diverse user demands. Furthermore, existing seat rail structures lack sufficient strength, making them prone to deformation under prolonged loads, leading to seat adjustment malfunctions and impacting the user experience.

[0004] Therefore, there is an urgent need to design a car seat sliding rail structure and a car seat that allows users to flexibly adjust the seat position according to their needs, optimizing the use of interior space. For example, by adjusting the seat's fore-aft and lateral directions, it can be adapted to various usage scenarios such as facilitating passenger entry and exit, expanding storage space, and improving riding comfort, thereby effectively meeting the diverse usage demands of users. At the same time, it can effectively improve the strength of the seat sliding rail structure, thereby improving the stability of seat adjustment and extending its service life. Utility Model Content

[0032] Existing seat rail designs are relatively simple, mostly employing a unidirectional rail layout. This results in limited usage scenarios, with most rails extending only longitudinally along the vehicle body, supporting only fore-and-aft seat movement. They fail to consider users' needs for lateral space adjustment in different scenarios, severely restricting seat space utilization and functional expansion. This prevents the full release of interior space potential and makes it difficult to meet increasingly diverse user demands. Furthermore, existing seat rail structures lack sufficient strength, making them prone to deformation under prolonged loads, leading to seat adjustment malfunctions and impacting the user experience.

[0033] To address the aforementioned issues, this application provides an automotive seat slide rail structure and an automotive seat. This structure and seat allow users to flexibly adjust the seat position according to their needs, optimizing the use of interior space. For example, by adjusting the seat's fore-aft and lateral directions, it can be adapted to various usage scenarios such as facilitating passenger entry and exit, expanding storage space, and improving seating comfort, thereby effectively meeting diverse user demands. Simultaneously, it effectively improves the strength of the seat slide rail structure, thereby enhancing the stability of seat adjustment and extending its service life.

[0034] The technical solutions of the embodiments of this application are described in detail below with reference to the accompanying drawings.

[0035] Example 1

[0036] Please see Figures 1-9 The automotive seat slide rail structure of this application includes a seat frame assembly 1, a first slide rail assembly 2, a first slide rail anti-detachment component 3, a bracket assembly 4, and a second slide rail assembly 5. The seat frame assembly 1, the first slide rail assembly 2, the bracket assembly 4, and the second slide rail assembly 5 are arranged sequentially from top to bottom. The first slide rail anti-detachment component 3 is disposed on one side of the bracket assembly 4 and located on the rear outer side of the bracket assembly 4. It is used to strengthen the structural strength of the first slide rail assembly 2 and prevent the first slide rail assembly 2 from deviating from the preset movement path.

[0037] The seat frame assembly 1 is detachably connected to the first slide rail assembly 2 via bolts 6. Figure 1 As shown, the seat frame assembly 1 has N mounting through holes, which are located on the fixing component of the seat frame assembly 1 and respectively at the front and rear ends of the fixing component. The first slide rail assembly 2 has N bolts 6, which are passed through the N mounting through holes and locked with nuts, thereby realizing the detachable fixed connection between the seat frame assembly 1 and the first slide rail assembly 2; for example, N is 6.

[0038] The first slide rail assembly 2 is mounted on the bracket assembly 4 and can move relative to the bracket assembly 4 in the left-right direction. Specifically, the first slide rail assembly 2 includes a first electric slide rail 21, a second electric slide rail 22, a first memory motor 23, and a module bracket 24. The first electric slide rail 21 and the second electric slide rail 22 are parallel and symmetrically arranged at the front and rear ends of the seat frame assembly 1 and extend in the left-right direction, i.e., N bolts 6 are respectively mounted on the first electric slide rail 21 and the second electric slide rail 22. The two ends of the module bracket 24 are respectively fixed to the first electric slide rail 21 and the second electric slide rail 22 by bolts. Specifically, the two ends of the module bracket 24 are respectively provided with fixing holes. Bolts are passed through the fixing holes and then tightened with nuts, thereby fixing the module bracket 24 to the first electric slide rail 21 and the second electric slide rail 22. For example, the module bracket 24 is also provided with several wiring harness mounting holes. Through the reserved wiring harness mounting holes, it is convenient to install functional modules such as ventilation module, heating module, memory module and massage module, so that the seat can realize ventilation, heating, memory and massage functions under the program control of the module.

[0039] The first memory motor 23 is connected to the first electric slide rail 21 and the second electric slide rail 22 via a mounting bracket 25, and is used to drive the first electric slide rail 21 and the second electric slide rail 22 to move. For example, the mounting bracket 25 is fixed to the first electric slide rail 21 and the second electric slide rail 22 by bolt assemblies and is located in the central region of the first electric slide rail 21 and the second electric slide rail 22. The first memory motor 23 is mounted on the mounting bracket 25. For example, the mounting bracket 25 is provided with a U-shaped locking block 251, and the output shaft 231 of the first memory motor 23 is disposed within the U-shaped locking block 251, thereby fixing the first memory motor 23 to the mounting bracket 25. A drive slider 232 is provided at the end of the output shaft 231 of the first memory motor 23. The drive slider 232 is disposed within the first electric slide rail 21 and the second electric slide rail 22, and is used to drive the first electric slide rail 21 and the second electric slide rail 22 to move. Specifically, the first electric slide rail 21 and the second electric slide rail 22 include a matching outer rail 211 and a movable inner rail 212. The outer rail 211 is generally U-shaped, and the movable inner rail 212 is generally Z-shaped and slidably embedded within the outer rail 211. The driving slider 232 is disposed within the movable inner rail 212 and is used to drive the movable inner rail 212 to move along the extension direction of the outer rail 211. To further prevent the movable inner rail 212 from dislodging, the top end of the outer rail 211 is bent inward and downward to form an inverted U-shape, and the bottom outer edge of the movable inner rail 212 is bent upward to form a U-shape that matches the outer rail 211. Thus, the movable inner rail 212 is limited on the outer rail 211 by the two interlocking U-shapes.

[0040] The bracket assembly 4 includes a first slide rail bracket 41, a second slide rail bracket 42, a third slide rail bracket 43, and a fourth slide rail bracket 44. The first slide rail bracket 41, the second slide rail bracket 42, the third slide rail bracket 43, and the fourth slide rail bracket 44 are connected at their ends by bolts, forming a frame shape. The first slide rail bracket 41 and the third slide rail bracket 43 are arranged parallel to each other in the front-to-back direction and are used to connect the first electric slide rail 21 and the second electric slide rail 22, respectively. The first slide rail bracket 41 and the third slide rail bracket 43 are each provided with two limiting blocks 45. One end of the limiting block 45 is integrally formed with the first slide rail bracket 41 or the third slide rail bracket 43, and the other end extends upward into the inner movable rail 212, thereby limiting the movement distance of the inner movable rail 212 by blocking the movement distance of the drive slider 232.

[0041] The first slide rail anti-detachment component 3 is hooked to the bracket assembly 4. Specifically, the bracket assembly 4 is also provided with a U-shaped groove 46; the U-shaped groove 46 is located on the outside of the third slide rail bracket 43, and the groove opening of the U-shaped groove 46 faces downward, and is integrally formed with the third slide rail bracket 43; the first slide rail anti-detachment component 3 is provided with a U-shaped hook 31 that matches the U-shaped groove 46. When the first slide rail anti-detachment component 3 hooks the U-shaped groove 46 through the U-shaped hook 31 structure and is quickly assembled onto the bracket assembly 4, the first slide rail anti-detachment component 3 can cover the top and outside of the second electric slide rail 22, thereby semi-enclosing the second electric slide rail 22, effectively strengthening the strength of the second electric slide rail 22 and preventing the second electric slide rail 22 from detaching.

[0042] The second slide rail assembly 5 is located below the bracket assembly 4 and is detachably connected to the bracket assembly 4 via bolts, for driving the bracket assembly 4 to move in the front-to-back direction. Specifically, the second slide rail assembly 5 includes a third electric slide rail 51, a fourth electric slide rail 52, and a second memory motor 53; the third electric slide rail 51 and the fourth electric slide rail 52 are arranged parallel and symmetrically at the left and right ends of the bracket assembly 4, extending in the front-to-back direction, and are detachably connected to the bracket assembly 4 respectively; the second memory motor 53 is mounted on the third electric slide rail 51 and the fourth electric slide rail 52 via a mounting bracket 25, for driving the third electric slide rail 51 and the fourth electric slide rail 52 to move in the front-to-back direction. It should be noted that the installation method between the third electric slide rail 51, the fourth electric slide rail 52, and the second memory motor 53 is the same as the installation method between the first electric slide rail 21, the second electric slide rail 22, and the first memory motor 23, and will not be repeated here.

[0043] Furthermore, in order to improve the strength and service life of the third electric slide rail 51 and / or the fourth electric slide rail 52, the second slide rail assembly 5 further includes an upper clamp 54 and a lower clamp 55; the upper clamp 54 is disposed at the top of the third electric slide rail 51 and / or the fourth electric slide rail 52, and extends and bends towards the inner side of the third electric slide rail 51 and / or the fourth electric slide rail 52 to form a bent portion; the lower clamp 55 is disposed at the bottom of the third electric slide rail 51 and / or the fourth electric slide rail 52, and extends and bends towards the inner side of the third electric slide rail 51 and the fourth electric slide rail 52, and forms a barb structure with the bent portion of the upper clamp 54. When the upper clamp 54 and the lower clamp 55 are fixed to the third electric slide rail 51 and / or the fourth electric slide rail 52 by rivets, they can wrap around the three sides of the third electric slide rail 51 and / or the fourth electric slide rail 52, thereby effectively strengthening the strength of the third electric slide rail 51 and / or the fourth electric slide rail 52, effectively preventing its deformation, and further improving its stability and service life.

[0044] Working principle:

[0045] After the seat frame assembly 1, the first slide rail assembly 2, the first slide rail anti-slip component 3, the bracket assembly 4, and the second slide rail assembly 5 are fixed with bolts and nuts, if the seat needs to be adjusted to the left or right, simply press the button on the seat to activate the first memory motor 23. This causes the first memory motor 23 to move the drive slider 232, which in turn moves the inner sliding rail 212 connected to it along the extension direction of the outer rail 211. This causes the seat frame assembly 1 to move synchronously to the left or right, thus achieving left-right adjustment of the seat. When the user needs to adjust the fore-aft position of the seat, simply activate the second memory motor 53. This causes the inner sliding rail 212 in the third electric slide rail 51 and the fourth electric slide rail 52 to move along the extension direction of the outer rail 211 (i.e., the fore-aft direction). This synchronously moves the bracket assembly 4, the first slide rail assembly 2, the first slide rail anti-slip component 3, and the seat frame assembly 1 synchronously to the fore-aft direction, thus achieving fore-aft adjustment of the seat.

[0046] In this first embodiment, the automotive seat slide rail structure provided by this application includes a seat frame assembly, a first slide rail assembly, a first slide rail anti-detachment component, a bracket assembly, and a second slide rail assembly. By respectively arranging the first and second slide rail assemblies above and below the bracket assembly, and vertically aligning their extension directions, the seat can be adjusted left and right via the first slide rail assembly and forward and backward via the second slide rail assembly, resulting in a compact overall structure. Furthermore, the first slide rail anti-detachment component not only improves the overall strength of the first electric slide rail but also effectively prevents the inner track of the first slide rail assembly from detaching from the outer track. The upper and lower clamps on the third and / or fourth electric slide rails effectively strengthen their strength and further improve their stability during movement by wrapping around their three surfaces. By designing the top of the outer track as an inverted U-shape and the bottom of the movable inner track as a U-shaped structure that matches the inverted U-shape, the movable inner track can be effectively prevented from detaching from the outer track. Compared to existing technologies, the solution provided in this application allows users to flexibly adjust the seat position according to their needs, optimizing the use of interior space. For example, by adjusting the seat's fore-aft and lateral directions, it can be adapted to various usage scenarios such as facilitating passenger entry and exit, expanding storage space, and improving riding comfort, thereby effectively meeting the diverse usage demands of users. Simultaneously, it effectively improves the strength of the seat slide rail structure, thereby enhancing the stability of seat adjustment and extending its service life.
