[0006] This utility model provides a leg rest slide rail structure for automobiles, comprising:

[0007] An outer slide rail is used to be fixedly connected to a leg support mounting bracket; the outer slide rail includes a first bottom wall and first side walls connected to both sides of the first bottom wall, each of the first side walls has a bent wall at the end away from the first bottom wall, the bent walls on the two first side walls are arranged opposite to each other, and a first opening is formed between the two bent walls, the first bottom wall, the first side wall and the bent wall form a cavity;

[0008] An inner slide rail is used to be fixedly connected to the seat. The inner slide rail is disposed in the cavity. The inner slide rail includes a second bottom wall and a second side wall connected to both sides of the second bottom wall. The second bottom wall is located on one side of the first opening.

[0009] A sliding component is disposed between the first sidewall and the adjacent second sidewall, and the inner slide rail and the outer slide rail are slidably engaged by the sliding component.

[0010] In this embodiment, the bent wall on the outer slide rail can directly mate with the second bottom wall of the inner slide rail, confining the inner slide rail within the inner cavity of the outer slide rail. This eliminates the need for additional clamping components, reducing the inner cavity size of the outer slide rail and consequently the cross-sectional size of the product. This results in a smaller footprint, making it suitable for use in confined spaces, expanding its application range and flexibility, and meeting the installation requirements of various frame structures. Furthermore, the leg support slide rail structure in this embodiment does not require additional clamping components, resulting in fewer components and a lighter weight. This maximizes product lightweighting while maintaining strength, meeting the lightweight design requirements of the entire vehicle and reducing manufacturing costs.

[0016] In one example, both the first recess and the second recess include a first inclined surface and a second inclined surface arranged at an angle.

[0017] In one example, at least one end of the outer slide rail is provided with a first limiting member, and the end of the inner slide rail is provided with a second limiting member. When the inner slide rail slides relative to the outer slide rail to a first position, the second limiting member abuts against the first limiting member to constrain the inner slide rail to slide inside the cavity.

[0018] In one example, the first bottom wall is provided with a first bent edge, which bends toward the first opening side, and the first limiting member is the first bent edge;

[0019] Alternatively / and, the second bottom wall is provided with a second bent edge, the second bent edge bends toward one side of the first bottom wall, and the second limiting member is the second bent edge.

[0020] In one example, a first connector is also included, one end of which is snapped into the first bottom wall on one side of the cavity, and the other end of which passes through the first bottom wall and is located outside the cavity to connect to the leg support mounting bracket.

[0037] This application provides an automobile, which includes a leg rest mounting bracket and a leg rest slide rail structure. The leg rest slide rail structure is disposed on the automobile seat and is mainly used to help increase the leg support area of ​​the passenger.

[0038] The leg support slide rail structure of this application embodiment includes an outer slide rail 1, an inner slide rail 2, and a sliding component 4. In use, the outer slide rail 1 is fixedly connected to the leg support mounting bracket. The outer slide rail 1 can be fixedly connected to the leg support mounting bracket by welding or bolts or other first connecting parts 6. The accompanying drawings of this application show the outer slide rail 1 fixedly connected to the leg support mounting bracket by bolts. Of course, the first connecting part 6 can also be a screw or other component. The outer slide rail 1 and the leg support mounting bracket are connected by detachable components such as bolts or screws, which facilitates the adjustment of their positions during assembly and the disassembly during maintenance. In this application embodiment, the leg support slide rail structure also includes a first connecting part 6. One end of the first connecting part 6 is engaged with the first bottom wall 11 located on one side of the cavity 101, and the other end of the first connecting part 6 passes through the first bottom wall 11 and is located outside the cavity 101 to connect to the leg support mounting bracket. As shown in the figure, the first bottom wall 11 is provided with a through hole, and the first connecting part 6 passes through the through hole.

[0039] In this embodiment, the outer slide rail 1 includes a first bottom wall 11 and two first side walls 12. The two first side walls 12 are connected to both sides of the first bottom wall 11 and extend along the sliding direction of the inner slide rail 2. Each first side wall 12 has a bent wall 13 at the end away from the first bottom wall 11. The bent walls 13 of the two first side walls 12 are bent relative to each other, and a first opening 15 is formed between the two bent walls 13. The first bottom wall 11, the first side walls 12, and the bent walls 13 form a cavity 101.

[0040] In this embodiment, the inner slide rail 2 is disposed inside the cavity 101, and the second connecting member 7 extends out of the cavity 101 from the first opening 15 to connect to the seat. The accompanying drawings show that the second connecting member 7 is a bolt; the number of bolts can be determined according to the specific application environment.

[0041] In this embodiment, the inner slide rail 2 includes a second bottom wall 21 and second side walls 22 connected to both sides of the second bottom wall 21. The second side walls 22 extend along the sliding direction, and the second bottom wall 21 is located on one side of the first opening 15, that is, the second side walls 22 are located between the second bottom wall 21 and the first bottom wall 11. In this embodiment, the bent wall 13 cooperates with the second bottom wall 21 to abut against it to prevent the inner slide rail 2 from dislodging from the cavity 101. That is, the width of the first opening 15 is smaller than the width of the second bottom wall 21, where width refers to the dimension perpendicular to the sliding direction. The two second side walls 22 form a second opening 25 facing the first bottom wall 11.

[0042] In this embodiment, the sliding component 4 is disposed between the first sidewall 12 and the adjacent second sidewall 22, and the inner slide rail 2 and the outer slide rail 1 are slidably engaged by the sliding component 4. That is, the sliding component 4 is disposed between the inner surface of the first sidewall 12 and the outer surface of the second sidewall 22. Typically, to improve the smoothness of sliding, two or more sliding components 4 are provided on one side of each second sidewall 22. In this embodiment, the sliding component 4 can be a sphere, or an ellipsoid, etc., as long as it can achieve smooth sliding between the two components.

[0043] In this embodiment, the bent wall 13 on the outer slide rail 1 can directly cooperate with the second bottom wall 21 of the inner slide rail 2, confining the inner slide rail 2 within the inner cavity of the outer slide rail 1. This eliminates the need for additional clamping components, which helps reduce the inner cavity size of the outer slide rail 1, i.e., reduces the cross-sectional size of the product. This results in a smaller footprint, making it suitable for use in confined spaces, expanding its application range and flexibility, and meeting the installation requirements of different frame structures. Furthermore, in this embodiment, the leg support slide rail structure does not require additional clamping components, resulting in fewer components and a lighter weight. While maintaining strength, this maximizes product lightweighting to meet the lightweight design requirements of the entire vehicle and reduces manufacturing costs.

[0044] In this embodiment, the leg support slide rail structure further includes a retainer 3. The retainer 3 includes two third sidewalls 31 and a connecting wall 32 connecting the two third sidewalls 31. The third sidewalls 31 are at least partially located between the first sidewall 12 and its corresponding second sidewall 22. The connecting wall 32 is located between the first bottom wall 11 and the second bottom wall 21. The sliding member 4 is disposed on the third sidewalls 31. The ends of the two second sidewalls 22 away from the second bottom wall 21 have second openings 25 facing the first bottom wall 11. The connecting wall 32 is located on one side of the second openings 25. That is, the two third sidewalls 31 of the retainer 3 form an upwardly open structure, and the inner slide rail 2 is at least partially located between the two third sidewalls 31.

[0045] In this embodiment, the sliding component 4 is integrated onto the retainer 3. The retainer 3 can support the sliding component 4, ensuring the stability of the installation and movement of the sliding component 4, preventing collisions between the sliding components 4, and ensuring that the sliding component 4 can move within a specified space. It can roll freely and prevent detachment. Furthermore, the integrated arrangement of each sliding component 4 facilitates rapid assembly. In addition, the leg support slide rail structure is compact and occupies little space, which is conducive to further reducing the product size.

[0046] In one specific embodiment, the connecting wall 32 has a protrusion 321 that protrudes toward the side away from the first bottom wall 11 and extends from the second opening 25 into the space between the second side walls 22. The protrusion 321 can increase the strength of the retainer 3 to a certain extent, and the protrusion 321 is provided at a local position on the connecting wall 32, so that the space between the protrusion 321 and the first bottom wall 11 can be relatively large, which facilitates the setting of the first connection on the first bottom wall 11.

[0047] The aforementioned sliding component 4 can be a sphere, and the material of the sphere can be steel. Two or more spheres are rotatably embedded in each third sidewall 31, with the spheres spaced apart along the sliding direction of the inner slide rail 2 and the outer slide rail 1. The sphere structure is simple and slides smoothly. Specifically, an assembly window can be pre-set on the third sidewall 31, the size of which can be slightly larger than the diameter of the sphere, allowing a robotic arm to press the sphere into the assembly window.

[0048] In this embodiment, the inner wall of the first sidewall 12 has a first recess 12A, and the outer wall of the second sidewall 22 has a second recess 22A. The openings of the first recess 12A and the second recess 22A face each other. The sphere makes point contact with the first recess 12A, and there are at least two contact points. The sphere also makes point contact with the second recess 22A, and there are at least two contact points. A rolling track for the sphere is formed between the first recess 12A and the second recess, which prevents the sphere from deviating and improves the smoothness of sliding. Furthermore, the sphere makes multiple contact points with the first sidewall 12 and the second sidewall 22, resulting in better force stability.

[0049] In one specific embodiment, both the first recess 12A and the second recess 22A include a first inclined surface 121 and a second inclined surface 122 arranged at an included angle. The same reference numerals are used herein to denote the inclined surfaces on the first sidewall 12 and the second sidewall 22. The machining of the inclined surfaces is relatively simple.

[0050] In this embodiment, at least one end of the outer slide rail 1 is provided with a first limiting member, and the end of the inner slide rail 2 is provided with a second limiting member. When the inner slide rail 2 slides relative to the outer slide rail 1 to a first position, the second limiting member abuts against the first limiting member to constrain the inner slide rail 2 to slide inside the cavity 101. The first limiting member can be provided on the first bottom wall 11 or the first side wall 12, and similarly, the second limiting member can be provided on the second bottom wall 21 or the second side wall 22.

[0051] The first and second limiting members can prevent the inner slide rail 2 from coming out of the cavity 101, thus improving the reliability of the assembly.

[0052] In one embodiment, the first bottom wall 11 is provided with a first bent edge 14, which bends toward the first opening 15, and the first limiting member is the first bent edge 14; similarly, the second bottom wall 21 is provided with a second bent edge 23, which bends toward the first bottom wall 11, and the second limiting member is the second bent edge 23. In this embodiment, the forming process of the first limiting member and the second limiting member is simple.

[0053] The inner slide rail 2, the outer slide rail 1, and the retainer 3 can be formed by stamping and bending sheet metal.

[0054] In this embodiment, the leg rest slide rail structure further includes a pad 5 and a second connecting member 7. The pad 5 is disposed on the side of the second bottom wall 21 opposite to the second side wall 22. One end of the second connecting member 7 is engaged with the surface of the second bottom wall 21 facing the first bottom wall 11, and the other end passes through the second bottom wall 21 and the pad 5 and extends out of the cavity 101 to connect to the seat. Figure 2 As shown, the pad 5 has a second through hole 51, and the second bottom wall 21 of the inner slide rail 2 has a first through hole 24. The upper end of the bolt passes through the first through hole 24 and the second through hole 51 in sequence and extends out of the cavity 101. The pad 5 can be a flat plate, which can improve the strength of the inner slide rail 2.
