Abstract
Description
Technical Field
[0001] The utility model belongs to the field of automotive hardware accessories, and particularly relates to a slider used in an automotive seat rail assembly. Background Art
[0002] The front-back adjustment of an automotive seat is mainly guided by a rail assembly. The rail assembly applied to an automotive seat generally includes a rail fixed to the vehicle base and a sliding assembly that can move along the rail. The seat is directly fixed to the sliding assembly, and when the sliding assembly moves, it drives the seat to move back and forth.
[0003] The sliding assembly is usually composed of multiple parts. As shown in the attached figure, a slider sheet metal part 100 of the sliding assembly is an important part for the opening and closing function and strength at the sliding function position. During production, steel balls 200 are usually installed and riveted tightly in the cavity inside the front end of the slider sheet metal part 100 to reinforce the force on the left and right sides and strengthen the support. Figure 1-2 However, during the assembly or use process, there is a risk of missing balls, which seriously affects the functional strength of the part. In addition, the addition of steel balls and riveting processes also increases the processing cost.
[0004] Summary of the Utility Model
[0005] The purpose of the utility model is to provide a slider used in an automotive seat rail assembly. The slider is a sheet metal part, and the slider includes a bottom plate, a left side plate, a right side plate, and a front end plate. The left side plate and the right side plate are arranged in parallel and are respectively erected on the left and right sides of the bottom plate. The front end plate is erected at the front end of the bottom plate. The upper end of the front end plate extends backward and is bent and curled into a curled part. The curled part is clamped between the left side plate and the right side plate.
[0006] The curled part includes a top part, a rear part, and an arc part. The top part extends backward from the upper end of the front end plate and is parallel to the bottom plate. The top part is connected to the front end plate through an arc edge. The rear part extends downward from the rear side of the top part and is parallel to the front end plate. The rear part is connected to the top part through an arc edge. The arc part is curled forward in an arc shape from the lower end of the rear part to be received in the space enclosed by the front end plate, the top part, and the rear part.
[0007] The bottom plate, the left side plate, the right side plate, the front end plate, and the curled part are formed by punching and bending a metal thin plate.
[0008] In this technical solution, by sandwiching a curled part between the left side plate and the right side plate, that is, the left and right ends of the curled part are respectively abutted against the left side plate and the right side plate, the support points are increased to reinforce the left and right forces and meet the strength requirements of the workpiece.
[0009] The curling part extends backward from the upper end of the front end plate and is bent and curled. It can be formed by curling in one step using a progressive die. In this solution, the curling structure replaces the bead reinforcement, which not only reduces materials and costs but also reduces process steps and improves production efficiency. In addition, the problem of bead leakage can be avoided, preventing the reinforcement function from failing. Description of the Drawings

[0016] The following further describes the solution of the present application in conjunction with the drawings:
[0017] Referring to Figure 3-7 , a slider for an automotive seat rail assembly, the slider includes a bottom plate 1, a left side plate 2, a right side plate 3, and a front end plate 4; the left side plate 2 and the right side plate 3 are arranged in parallel and are respectively erected on the left and right sides of the bottom plate 1, and the front end plate 4 is erected at the front end of the bottom plate 1; the upper end of the front end plate 4 extends backward and is bent and curled into a curling part 5; the curling part 5 is sandwiched between the left side plate 2 and the right side plate 3.
[0018] In this technical solution, by sandwiching the curling part 5 between the left side plate 2 and the right side plate 3, that is, the left and right ends of the curling part 5 respectively abut against the left side plate 2 and the right side plate 3, the support points are increased to reinforce the left and right forces, meeting the strength requirements of the workpiece.
[0019] The curling part 5 extends backward from the upper end of the front end plate 4 and is bent and curled. It can be formed by curling in one step using a progressive die. In this solution, the curling structure replaces the bead reinforcement, which not only reduces materials and costs but also reduces process steps and improves production efficiency. In addition, the problem of bead leakage can be avoided, preventing the reinforcement function from failing.
[0020] As Figure 7As shown, the curling part 5 includes a top part 51, a rear part 52, and an arc part 53; the top part 51 extends backward from the upper end of the front end plate 4 and is parallel to the bottom plate 1, and the top part 51 and the front end plate 4 are connected by an arc edge; the rear part 52 extends downward from the rear side of the top part 51 and is parallel to the front end plate 4, and the rear part 52 and the top part 51 are connected by an arc edge; the arc part 53 curls forward in an arc shape from the lower end of the rear part 52 to be received in the space enclosed by the front end plate 4, the top part 51, and the rear part 52.
[0021] The top part 51 is parallel to the bottom plate 1, and the rear part 52 is parallel to the front end plate 4, forming a support structure with an outer square and an inner circle, which has high stability.
