Embodiment 1

[0067] see Figure 6 , the seat slide mechanism shown in the figure includes a pair of lower slide rails 100 fixed on the vehicle floor and a pair of upper slide rail assemblies 200 hinged with the seat (Note Figure 6 Only one lower rail 100 and a set of upper slide rail assemblies 200 are shown in the assembly diagram, and the other lower rail 100 and a set of upper slide rail assemblies 200 have the same structure and assembly relationship).

[0068] see Figure 7 , the cross-sectional shape of the lower rail 100 is a concave shape with the upper bottom removed, and the groove 110 in the middle of the lower rail 100 with the upper bottom groove removed constitutes a rolling groove for the upper rail assembly 200 to move back and forth. The two sides of the groove 110 The downward turning edges 131, 132 and the upward turning edges 141, 142 on both sides of the lower rail 100 respectively define the left and right lower turning edges 211, 221 in the upper slide rail assembl...

Embodiment 2

[0082] The difference between the seat slide rail mechanism of this embodiment and the seat slide rail mechanism of Embodiment 1 is that the vertical gap elimination mechanism 700 is slightly different, and the rest are the same as Embodiment 1.

[0083] see Figure 10 , the vertical clearance elimination mechanism 700 of this embodiment includes a small roller 711 , a swing piece 721 and a torsion spring 731 .

[0084] The swinging piece 721 is a roughly L-shaped swinging piece. The middle position of the swinging piece 721 has a fulcrum, and the fulcrum is hinged on the front side of the lower right flange 221 of the upper right slide rail plate 220 through a rivet 741. The swinging piece 721 Can swing around the rivet 741.

[0085] The small roller 711 is arranged on one end of the swing piece 721 through a rivet 751 shaft, and the other end of the swing piece 721 is connected to one end of the torsion spring 731, corresponding to the group of vertical clearance eliminatio...

Embodiment 3

[0089] The difference between the seat slide rail mechanism of this embodiment and the seat slide rail mechanism of Embodiment 1 is that the vertical gap elimination mechanism 700 is slightly different, and the rest are the same as Embodiment 1.

[0090] see Figure 11 In this embodiment, two groups of vertical gap elimination mechanisms 700 are respectively installed on the front and rear positions of the right lower flange 221 of the right upper slide rail plate 220 . The two groups of vertical clearance elimination mechanisms 700 share a torsion spring 732 .

[0091] Each set of vertical gap elimination mechanisms 700 also includes a small roller 712 and a swing piece 722 .

[0092] Each group of swinging pieces 722 is a roughly L-shaped swinging piece. The middle position of the swinging piece 722 has a fulcrum, and the fulcrum is hinged on the front and rear sides of the right lower flange 221 of the right upper slide rail plate 220 through a rivet 742. Sheet 722 can sw...

Abstract

The invention discloses a seat sliding rail mechanism which comprises an upper sliding rail assembly hinged to a seat, and a lower sliding rail arranged on a vehicle body floor, wherein the upper sliding rail assembly is slidably arranged on the lower sliding rail; a rolling body arranged on the upper sliding rail assembly rolls on the lower sliding rail and transmits the borne weight to the lower sliding rail; a locking mechanism is arranged on the upper sliding rail assembly and locks the upper sliding rail assembly at a proper position of the lower sliding rail in a locking state; and the seat sliding rail mechanism also comprises a vertical direction gap elimination mechanism which is arranged on the upper sliding rail assembly, acts on the lower sliding rail and is used for eliminating a gap between the upper sliding rail assembly and the lower sliding rail in the vertical direction. By utilizing the vertical direction gap elimination mechanism, the gap between the upper sliding rail assembly and the lower sliding rail in the vertical direction is completely eliminated, and the continuous and uncomfortable vibration noise generated by the seat is further reduced when an automobile runs on a bumpy road.

Description

technical field [0001] The invention relates to the technical field of car seats, in particular to a seat slide rail mechanism. Background technique [0002] According to the statistics of the automobile market in 2011, due to its large passenger space and comfortable environment, the sales volume of MPV models in the field of passenger vehicles has increased year by year, and has become a new growth point for various vehicle manufacturers. However, the second and third rows of seats currently on the market often have flaws in terms of comfort and adjustment range, such as: 1. Due to the short slide rails, the front and rear adjustment range of the second row of seats is small, and passengers cannot obtain a larger seating space; 2. The three rows of seats cannot be adjusted forward and backward, and the luggage space is limited; 3. The second row of seats still adopts conventional 3-point seat belts, which makes passengers less comfortable to ride; 4. There is a gap in the ...
