Description

Technical Field

[0001] The utility model relates to the technical field of automobile seat slide rails, in particular to an aluminum alloy lower slide rail structure. Background Art

[0002] As car owners' requirements for car seat comfort continue to increase, seats with extra-long travel are installed in large quantities on various cars. The lower rail of such seat products is generally longer. Since the upper rail fixed to the bottom of the seat is relatively short, the upper rail slides on the lower rail. During assembly and use, dust and impurities will enter the lower rail and accumulate, causing the upper rail to be blocked when sliding along the lower rail. Currently, there are few dust-proof measures for the lower rail. The existing dust-proof structures are either not highly closed and have poor dust-proof effects, or are inconvenient to install, have low stability, and are prone to wrinkling or even falling off. Utility Model Content

[0003] In view of the problems existing in the above-mentioned prior art, the utility model aims to provide an aluminum alloy lower slide rail structure to solve the problem that dust and impurities enter the lower slide rail and accumulate, causing the upper slide rail to be blocked when sliding along the lower slide rail.

[0004] The detachable lower rail dust cover comprises a left dust cover covering the left top of the lower rail body and a right dust cover covering the right top of the lower rail body, and the left dust cover and the right dust cover extend close to each other. The left and right sides of the lower rail body are provided with lower rail dustproof mounting grooves, and the left and right dust covers are provided with clamping protrusions that are mutually buckled with the corresponding side lower rail dustproof mounting grooves, and the top of the lower rail body is also provided with two notches, which are symmetrically arranged on the inner tops of the two lower rail anti-detachment hooks, and the left and right dust covers are provided with step protrusions at the notches corresponding to the same side, and the step protrusions are placed in the corresponding side notches.

[0005] In the above scheme: the top two sides of the lower slide rail body extend outwardly to form installation wings, the lower slide rail dustproof installation slot is arranged on the installation wings, and the lower slide rail dustproof installation slot is arc-shaped. The lower slide rail dustproof installation slot is arranged on the outside, that is, the fixed position of the left dust cover, the right dust cover and the lower slide rail body is arranged on the outside, so that when the upper slide rail body slides along the lower slide rail body, the inner ends of the left dust cover and the right dust cover can be squeezed by the upper slide rail body and can be separated smoothly.

[0006] In the above scheme: the left and right outer side walls of the lower slide rail body are both provided with ear structures, and the ear structures cooperate with the corresponding outer side walls to form a dustproof mounting slot of the lower slide rail, and the dustproof mounting slot of the lower slide rail is in the shape of a barb. The dustproof mounting slot of the lower slide rail is arranged on the outside, that is, the fixed position of the left dust cover, the right dust cover and the lower slide rail body is arranged on the outside, so that when the upper slide rail body slides along the lower slide rail body, the inner ends of the left dust cover and the right dust cover can be squeezed by the upper slide rail body and can be separated smoothly.

[0007] In the above scheme: the inwardly bent parts of the tops of the left and right side walls of the lower slide rail body are provided with arc-shaped surfaces, which are used to make the auxiliary rollers of the upper slide rail body slide back and forth along the arc-shaped surfaces.

[0008] In the above scheme: the bottom of the lower slide rail body is provided with a mounting plane that can be connected to the vehicle body, a row of mounting holes are provided at intervals in front and behind the mounting plane, and bolts are provided to connect with the vehicle body floor, so the installation is convenient and fast, and the connection is stable.

[0009] In the above scheme: the main body of the lower slide rail is made of aluminum alloy, and the length of the main body of the lower slide rail is 0.5m~2m. Compared with high-strength steel with great processing difficulty, complex process and heavy weight, aluminum alloy has good strength, simple process and light weight; it belongs to the range of long slide rails, and is suitable for MPVs, SUVs, etc. where the first and second rows share slide rails or the second and third rows share slide rails. The use of aluminum alloy also meets the structural strength requirements of long slide rails, and the material selection and length are reasonable.

[0010] The beneficial effects of the utility model are:

[0011] 1. The detachable lower rail dust cover consists of a left dust cover and a right dust cover, which are directly buckled and installed on the top of the lower rail, and the installation is quick and convenient; 2. The left dust cover and the right dust cover cooperate to cover the upper opening of the lower rail as much as possible, effectively preventing dust from entering the inner cavity of the lower rail during the assembly and use of the lower rail, and does not affect the sliding of the upper rail along the lower rail; 3. The step protrusion cooperates with the notch, and also has a certain snap-fitting and fixing effect on the dust cover, and the contact connection between the two does not affect the sliding of the upper rail along the lower rail; when the upper rail slides along the lower rail, the inner ends of the left dust cover and the right dust cover are squeezed by the upper rail and can be automatically lifted; moreover, the setting of the step protrusion increases the thickness of the inner ends of the two dust covers, thereby increasing the wear resistance of the dust covers and extending the service life of the dust covers, while avoiding the curling of the inner end edges of the two dust covers due to too thin thickness, resulting in an increase in the opening between the left dust cover and the right dust cover, affecting the shielding effect of the upper opening of the lower rail.
