Description

Technical Field

[0001] The utility model belongs to the field of vehicle seats, and particularly relates to a slide rail mechanism of a vehicle seat. Background Art

[0002] A vehicle seat slide rail is a mechanical component at the bottom of the seat for moving back and forth, which enables the driver or passenger to adjust the position of the seat according to their own needs and is crucial for ensuring the smooth and safe movement of the seat.

[0003] Some of the existing vehicle seat slide rails have openings facing upwards. After long-term use, dust and debris will enter the slide rails, making the front-back sliding adjustment of the vehicle seat not smooth, affecting the position adjustment of the seat and resulting in a poor riding experience. Therefore, a new slide rail mechanism for vehicle seats is needed. Summary of the Utility Model

[0004] To solve the above problems, the utility model discloses a slide rail mechanism of a vehicle seat.

[0005] To achieve the above object, the technical solution of the utility model is as follows:

[0006] A slide rail mechanism of a vehicle seat includes two parallel fixed slide rails which are mirror-symmetrically arranged. A slide seat is slidably installed in the sliding cavity of each fixed slide rail, and the bottom of the slide seat extends out of the sliding cavity from the side wall of the fixed slide rail. A plurality of parallel rollers are slidably installed at the top end of each slide seat, and the bottom of each roller is in rolling contact with the fixed slide rail. The two ends of each slide seat are fixedly connected to the ends of the same flexible curtain, and the two side edges of each flexible curtain are snapped into the annular chute of the adjacent fixed slide rail. The two slide seats are commonly connected to an installation seat, and a locking mechanism is arranged between the installation seat and the two fixed slide rails.

[0007] As a preferred technical solution of the utility model, each end face of each fixed slide rail is blocked by an end cover, and support plates are installed at the openings of both ends of each fixed slide rail facing the installation seat.

[0008] As a preferred technical solution of the utility model, a support bar is inlaid in the opening of each fixed slide rail facing away from the installation seat, and through holes are arranged at both ends of the bottom of each fixed slide rail.

[0009] As a preferred technical solution of the utility model, the middle part of each flexible curtain is composed of a flexible belt, metal edges are arranged on both sides of each flexible belt, and each metal edge is slidably snapped into the adjacent annular chute.

[0010] As a preferred technical solution of the present utility model, the locking mechanism includes: a rotating seat fixedly connected to the lower part of the mounting seat, the rotating seat is rotatably connected with a rotating clamping rod, and the rotating shaft of the rotating clamping rod can slide up and down in the vertical direction. At the top of each fixed slide rail, a clamping strip provided with a plurality of clamping positions is fixedly connected, and the two ends of the rotating clamping rod are adapted to the clamping positions of the clamping strip.

[0011] As a preferred technical solution of the present utility model, a spring is inserted into the round hole at the top of the rotating clamping rod, and the top of the spring is inserted into the round hole of the mounting seat.

[0012] As a preferred technical solution of the present utility model, a lifting handle is fixedly connected to the side of the rotating clamping rod away from the mounting seat.

[0013] The beneficial effects of the present utility model are as follows:

[0014] First, when adjusting the position of the car seat, pull up the lifting handle to make the rotating clamping rod disengage from the clamping position of the clamping strip, then push the mounting seat to move to a suitable position, and then release the lifting handle. Under the elastic force of the spring, the rotating clamping rod moves downward, so that the end of the rotating clamping rod is clamped into the clamping position of the clamping strip, and the position of the car seat is fixed. Thanks to the pulling type seat adjustment method, the seat adjustment is convenient and fast;

[0015] Second, when the mounting seat moves, the sliding seat is suspended by the roller and slides in the sliding cavity of the fixed slide rail, and the flexible curtain slides in the annular chute as the adjacent sliding seat moves, so as to close the channel communicating the sliding cavity with the outside as much as possible. Thanks to the setting of the flexible curtain, the probability of dust entering the rolling area of the roller is reduced, the rolling influence on the roller is reduced, and the adjustment of the car seat can be kept smooth for a long time.

[0029] Please refer to Figures 1-7 , a slide rail mechanism of an automobile seat, including two mutually parallel fixed slide rails 1, and the two fixed slide rails 1 are arranged in a mirror image. A slide seat 2 is slidably installed in the sliding cavity 101 of each fixed slide rail 1, and the bottom of the slide seat 2 extends out of the sliding cavity 101 from the side wall of the fixed slide rail 1. A plurality of mutually parallel rollers 3 are slidably installed at the top end of each slide seat 2, and the bottom of each roller 3 is in rolling contact with the fixed slide rail 1. The two ends of each of the said slide seats 2 are fixedly connected to the end of the same flexible curtain 4, and the two side edges of each flexible curtain 4 are clamped into the annular chute 102 of the adjacent fixed slide rail 1. The flexible curtain 4 slides as the adjacent slide seat 2 moves, reducing the probability of dust entering the rolling area of the roller 3 and reducing the rolling influence on the roller 3. The two slide seats 2 are jointly connected to a mounting seat 7, wherein the bottom of the mounting seat 7 is fixedly connected to the part of the slide seat 2 extending out of the sliding cavity 101. A plurality of through holes are provided at the top of the mounting seat 7 for fixedly connecting with the seat of the seat. Reinforcing ribs 13 are provided at the two corners of the mounting seat 7. A locking mechanism is provided between the mounting seat 7 and the two fixed slide rails 1 for fixing after the seat adjusts its position.

[0030] The two end faces of each fixed slide rail 1 are respectively blocked with an end cover 5, and support plates 6 are installed at the openings of each fixed slide rail 1 at both ends facing the mounting seat 7. The end cover 5 is used to reduce the entry of dust into the sliding cavity 101. The support plate 6 is used to enhance the strength of the opening of the fixed slide rail 1. The end cover 5 and the support plate 6 are both mounted on the fixed slide rail 1 by bolts. A support strip 103 is embedded in the opening of each fixed slide rail 1 facing away from the mounting seat 7, and through holes are provided at both ends of the bottom of each fixed slide rail 1. The support strip 103 is used to enhance the strength of the opening of the fixed slide rail 1. The through holes at both ends of the fixed slide rail 1 are used to fix it to the vehicle body by bolts and nuts.

[0031] The middle part of each flexible curtain 4 is composed of a flexible belt 401, and metal edging 402 is provided on both sides of each flexible belt 401, and each metal edging 402 is slidably inserted into the adjacent annular groove 102. The metal edging 402 is made of elastic metal sheets to enhance the smoothness and wear resistance of the flexible curtain 4 sliding in the annular groove 102.

[0032] The locking mechanism includes: a rotating seat 9 fixedly connected to the bottom of the mounting seat 7. The rotating seat 9 is rotatably connected to a rotating clamping rod 10, and the rotating shaft of the rotating clamping rod 10 can slide up and down in the vertical direction. A clamping strip 8 with a plurality of clamping positions is fixedly connected to the top of each fixed slide rail 1, and the two ends of the rotating clamping rod 10 are adapted to the clamping positions of the clamping strip 8. The clamping positions of the clamping strip 8 are linearly and evenly distributed. A spring 11 is inserted into the circular hole at the top of the rotating clamping rod 10, and the top of the spring 11 is inserted into the circular hole of the mounting seat 7. A lifting handle 12 is fixedly connected to the side of the rotating clamping rod 10 away from the mounting seat 7, and the lifting handle 12 is bent upward.

[0033] Working principle:

[0034] When adjusting the position of the car seat, the lifting handle 12 is pulled upward to move the rotating clamping rod 10 upward, and the rotating clamping rod 10 partially rotates around its own rotation axis, so that the rotating clamping rod 10 is out of the position of the clamping strip 8, and then the mounting seat 7 is pushed to move to a suitable position, and then the lifting handle 12 is released. Under the elastic force of the spring 11, the rotating clamping rod 10 moves downward, and the rotating clamping rod 10 partially rotates around its own rotation axis, so that the end of the rotating clamping rod 10 is clamped into the clamping position of the clamping strip 8, and the position of the car seat is fixed;

[0035] When the mounting seat 7 moves, the slide 2 is suspended by the roller 3 and slides in the sliding cavity 101 of the fixed slide rail 1, and the flexible curtain 4 slides in the annular slide groove 102 as the adjacent slide 2 moves, thereby closing the channel connecting the sliding cavity 101 to the outside world as much as possible, reducing the probability of dust entering the rolling area of the roller 3, and reducing the impact on the rolling of the roller 3.

[0036] It should be noted that the above content only illustrates the technical idea of the present utility model, and the protection scope of the present utility model cannot be limited thereby. For those of ordinary skill in the art, without departing from the principle of the present utility model, several improvements and refinements can still be made, and these improvements and refinements all fall within the protection scope of the claims of the present utility model.
