Description

Technical Field

[0001] This utility model belongs to the field of automotive seat slide rails, specifically, it relates to a slide rail with good stress distribution, low noise, low cost, and high strength. Background Technology

[0002] With the increasing sales of automobiles in both the domestic and international markets, car seats are one of the core components of automobiles, and sliding rails are a core part of seats, so their demand is also increasing rapidly.

[0003] Currently available slide rails use an upper rail + lower rail or upper rail + cage + lower rail structure. However, the cage is a separate type, which can cause the steel balls to get stuck when the slide rail is in use. Although this does not affect normal use, it increases the sliding power and also increases the noise. Utility Model Content

[0004] To address the above deficiencies, this utility model provides a slide rail with good force distribution, low noise, low cost, and high strength, including an upper rail and a lower rail that are compatible with each other. The upper rail and the lower rail are combined to form a convex shape, and the upper edges of the left and right sides of the upper rail are inserted into the bent ends of the left and right sides of the lower rail.

[0005] An integrated retainer is also snapped onto the outside of the lower rail;

[0006] A first R-angle support plate is fixed to one side of each of the two upper edges that are close to each other. The first R-angle support plate is arranged opposite to the corner of the bend end. A second R-angle support plate is fixed to each of the two bend ends at the bottom of the lower rail. The two second R-angle support plates are respectively arranged opposite to the lower edges of the left and right sides of the upper rail.

[0007] Furthermore, both the first R-angle support plate and the second R-angle support plate are used to support the steel ball.

[0008] Furthermore, both ends of the integrated cage are provided with several ball grooves that are adapted to the steel balls.

[0009] Furthermore, the upper and lower rails are 1.5mm thick and made of HC800LA material.

[0010] Compared with the prior art, the present invention has the following advantages:

[0011] When in use, this slide rail uses an integrated molded cage to make the force more stable and reduce the generation of abnormal noise during operation. At the same time, it is made of HC800LA material, which makes it lightweight and high-strength. Attached Figure Description

[0017] To facilitate understanding of this utility model, the device of this utility model will be described more fully below with reference to the accompanying drawings. Embodiments of the device are shown in the drawings. However, this device can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to make the disclosure of this utility model more thorough and complete.

[0018] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "setting" should be interpreted broadly. For example, they can refer to a fixed connection or setting, a detachable connection or setting, or an integral connection or setting. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0019] Example

[0020] like Figure 1-3 As shown, this embodiment provides a slide rail with good force distribution, low noise, low cost, and high strength, including an upper rail 1 and a lower rail 2 that are compatible with each other. The upper rail 1 and the lower rail 2 are combined to form a convex shape, and the upper edges of the left and right sides of the upper rail 1 are inserted into the bent ends of the left and right sides of the lower rail 2, thereby realizing the sliding operation of the upper rail 1 inside the lower rail 2. It should be noted that bolt holes are opened at the upper rail 1 and the lower rail 2 respectively, for fixing to the bottom of the seat and the frame.

[0021] The lower rail 2 is also fitted with an integrated retainer 3. The integrated retainer 3 can effectively solve the problem of slide rail jamming in the market. Even if a jamming point is encountered, because it is a single body, the steel ball on the other side that does not encounter a jamming point will drive the entire retainer assembly to pass the jamming point, so that the slide rail continues to run smoothly.

[0022] Two upper edges are each fixed with a first R-angle support plate 11 on the side that is close to each other. The first R-angle support plate 11 is set opposite to the corner of the bending end. Two bending ends at the bottom of the lower rail 2 are each fixed with a second R-angle support plate 21. The two second R-angle support plates 21 are respectively set opposite to the lower edges of the left and right sides of the upper rail 1. The planar form can better distribute the force on the rail and has stronger stability.

[0023] like Figure 4 As shown, Figure 4 The schematic diagram of the steel ball state after removing the integrated retainer 3 shows more clearly that the first R-angle support plate 11 and the second R-angle support plate 21 are both used to support the steel ball, and at the same time, both ends of the integrated retainer 3 are provided with several ball grooves that are adapted to the steel ball.

[0024] In addition, the upper rail 1 and the lower rail 2 are 1.5mm thick and made of HC800LA material. Because they are made of high-strength steel, the steel has a large resilience. In addition, the upper steel ball is interference-fitted to expand the lower rail 2. Therefore, after being subjected to force, the lower rail 2 will rebound, so that the upper and lower rails tightly hold the steel ball, thereby reducing the gap and reducing the possibility of abnormal noise.

[0025] It should be noted that the structure described in this utility model can be implemented in many different forms and is not limited to the embodiments described. Any equivalent transformations made by those skilled in the art based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, such as the loading and unloading of other items, are included within the protection scope of this utility model.
