Description

Technical Field

[0001] This utility model relates to the field of seat slide rail technology, and more specifically, to a seat slide rail mechanism with a rolling friction reduction structure. Background Technology

[0002] Seat rails are an important component of car seats. Their main function is to allow the seat to move forward and backward, thereby providing passengers with a more comfortable riding experience.

[0003] Because traditional car seat rails generally use a rigid sliding method between the track and the rail groove, the seat is often affected by factors such as the driver's weight, the impact force when the driver gets in and out, and the vibration during vehicle operation. The internal mechanical structure is prone to wear and tear. As the usage time increases, the wear and tear will gradually intensify, causing the seat to become loose on the rail. A loose seat will not only affect the comfort of riding, but also produce abnormal noises and distract the driver's attention.

[0004] Therefore, there is an urgent need for a seat slide mechanism with a rolling friction reduction structure to improve the shortcomings of the existing technology. Utility Model Content

[0005] The purpose of this invention is to provide a seat slide rail mechanism with a rolling friction reduction structure to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides a seat slide rail mechanism with a rolling friction reduction structure, including a seat. A slide rail assembly for adjusting the seat is fixedly connected to the lower surface of the seat. The slide rail assembly includes a drive mechanism, a sliding mechanism, and a track mechanism. Both ends of the drive assembly are fixedly connected to the sliding mechanism. The sliding mechanism is slidably connected to the track mechanism. The sliding mechanism includes a sliding frame. A roller is rotatably connected inside the sliding frame. Grooves are provided on both sides of the sliding frame. Ball bearings are rotatably connected in the grooves. The ball bearings and roller are slidably connected to the track mechanism. The track mechanism includes a track frame. The sliding frame is inserted into the track frame.

[0007] As a further improvement to this technical solution, the slide rail assembly also includes a connecting block, the two ends of which are fixedly connected to the upper surface of the sliding frame, and the upper surface of the sliding frame is provided with a fixing hole for fixing the sliding mechanism to the lower surface of the seat.

[0008] As a further improvement to this technical solution, the driving mechanism includes a driving outer frame, which is fixedly connected to the end of the upper surface of the sliding frame away from the connecting block, and a buckle is fixedly connected inside the driving outer frame.

[0009] As a further improvement to this technical solution, the buckle is engaged with a slide rail motor, and the two ends of the slide rail motor are respectively fixedly connected to a rotating shaft, and the other end of the rotating shaft is fixedly connected to a gear.

[0010] As a further improvement to this technical solution, the lower surface of the track frame is provided with a fixing hole 2 for fixing, the upper surface inside the track frame is fixedly connected with a toothed groove, a through groove is provided on one side of the track frame, the middle part of the roller is lower than the two ends, and the roller rolls above the toothed groove.

[0011] As a further improvement to this technical solution, one end of the rotating shaft slides within the through groove, and the gear meshes with the tooth groove.

[0012] As a further improvement to this technical solution, a fixed angle bracket is fixedly connected to the surface of the track motor, and the fixed angle bracket is fixedly connected to the drive frame.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] This seat slide rail mechanism with a rolling friction reduction structure uses ball bearings on both sides of the sliding frame to effectively reduce the lateral friction experienced by the seat during adjustment. When the seat is adjusted forward or backward, the ball bearings roll between the slide rail and the seat structure, transforming the original sliding friction into rolling friction. The frictional force of rolling friction is much less than that of sliding friction, making the left-right movement of the seat smoother and reducing resistance during adjustment. The rollers at the bottom slide along the track groove, which also significantly reduces the friction during the forward and backward movement of the seat. The rollers roll along the track groove, making the longitudinal movement of the seat very easy. Compared to traditional sliding slide rails, this rolling design greatly reduces the force required to move the seat. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figures 1-5 As shown, this embodiment provides a seat slide rail mechanism with a rolling friction reduction structure, including a seat 1. A slide rail assembly 2 for adjusting the seat 1 is fixedly connected to the lower surface of the seat 1. The slide rail assembly 2 includes a drive mechanism 21, a sliding mechanism 22, and a track mechanism 23. Both ends of the drive assembly are fixedly connected to the sliding mechanism 22. The sliding mechanism 22 is slidably connected to the track mechanism 23. The sliding mechanism 22 includes a sliding frame 220. A roller 224 is rotatably connected inside the sliding frame 220. Grooves 222 are provided on both sides of the sliding frame 220. A ball bearing 223 is rotatably connected inside the groove 222. The ball bearing 223 and the roller 224 are rotatably connected to the track mechanism 23. The track mechanism 23 includes a track frame 230. The sliding frame 220 is inserted into the track frame 230.

[0027] The working principle described above is as follows: When the position of seat 1 needs to be adjusted, the drive mechanism 21 first starts to operate. Since the two ends of the drive assembly are fixedly connected to the sliding frame 220 of the sliding mechanism 22, the power generated by the drive mechanism 21 can drive the sliding frame 220 to move. The roller 224 rotatably connected inside the sliding frame 220 and the ball bearings 223 rotatably connected in the grooves 222 on both sides cooperate with the track frame 230 of the track mechanism 23. The roller 224 rolls in the track frame 230, allowing the sliding frame 220 to move smoothly in the front and back directions. The ball bearings 223 in the grooves 222 on both sides roll at the corresponding positions in the track frame 230, reducing the lateral friction generated when the sliding frame 220 moves and ensuring the stability of the movement. At the same time, the sliding frame 220 is inserted into the track frame 230, which not only restricts the relative position of the two, but also ensures good sliding guidance. In this way, the precise, stable and efficient position adjustment of seat 1 on the slide rail assembly 2 can be achieved.

[0028] In order to improve the structural strength of the slide rail assembly 2, the slide rail assembly 2 in this embodiment also includes a connecting block 20. The two ends of the connecting block 20 are fixedly connected to the upper surface of the sliding frame 220. The upper surface of the sliding frame 220 is provided with a fixing hole 221 for fixing the sliding mechanism 22 to the lower surface of the seat 1. The fixing hole 221 on the sliding frame 220 is used to securely install the sliding mechanism 22 on the lower surface of the seat 1, ensuring that the seat 1 and the sliding frame 220 are firmly connected. During the adjustment of the seat 1, the entire structure can operate stably. When the sliding frame 220 moves in the track frame 230 or bears the pressure transmitted from the seat 1, the connecting block 20 can disperse the stress and prevent the sliding frame 220 from deforming due to uneven force.

[0029] To facilitate motor fixation, in this embodiment, the drive mechanism 21 includes a drive frame 210. The drive frame 210 is fixedly connected to the end of the upper surface of the sliding frame 220 away from the connecting block 20. A buckle 211 is fixedly connected inside the drive frame 210. The drive frame 210 is fixed to the upper surface of the sliding frame 220, providing a stable mounting base for the slide rail motor 212. The internal buckle 211 can precisely engage the slide rail motor 212, preventing displacement of the motor during operation.

[0030] To enable adjustment of seat 1, in this embodiment, a slide rail motor 212 is engaged with a clip 211. Two rotating shafts 214 are fixedly connected to both ends of the slide rail motor 212, and a gear 215 is fixedly connected to the other end of each shaft 214. A fixing bracket 213 is fixedly connected to the surface of the slide rail motor and is also fixedly connected to the drive frame 210. When the slide rail motor 212 starts, the rotating shafts 214 at both ends rotate, causing the gear 215 fixed to the other end of the shafts 214 to rotate. Since the gear 215 meshes with the toothed grooves 232 on the upper surface of the track frame 230, the rotation of the gear 215 is converted into linear motion along the toothed grooves 232, thereby pushing the connected sliding frame 220 to move within the track frame 230. The fixing bracket 213 ensures the stability of the motor within the drive frame 210, ensuring stable power transmission. Thus, the fore-and-aft adjustment of seat 1 can be achieved through the rotation of the motor.

[0031] To enable forward and backward movement, in this embodiment, the lower surface of the track frame 230 is provided with a fixing hole 231 for fixation. A toothed groove 232 is fixedly connected to the upper surface of the track frame 230. A through groove 233 is provided on one side of the track frame 230. The middle part of the roller 224 is lower than both ends, and the roller 224 rolls above the toothed groove 232. One end of the rotating shaft 214 slides within the through groove 233. The gear 215 meshes with the toothed groove 232. The fixing hole 231 on the lower surface of the track frame 230 is used to fix the track frame 230 at a specific position on the vehicle, providing stable support for the entire seat slide rail mechanism with rolling friction reduction structure. The toothed groove 232 on the upper surface of the track frame 230 cooperates with the gear 215 to achieve power transmission, while the through groove 233 on one side provides sliding space for one end of the rotating shaft 214, ensuring that the rotating shaft 214 does not detach from the track frame 230 during rotation. The middle part of the roller 224 is lower than the two ends, so that when it rolls above the tooth groove 232, it can maintain a stable rolling state and form a good fit with the tooth groove 232. When the gear 215 drives the sliding frame 220 to move, the roller 224 plays a role in auxiliary support and reducing friction, helping the seat 1 to move smoothly back and forth.

[0032] In this embodiment, a seat slide rail mechanism with a rolling friction reduction structure is used such that when the position of the seat 1 needs to be adjusted, the slide rail motor 212 is first started, and the rotating shafts 214 at both ends of the motor rotate accordingly, driving the gear 215 fixed at the other end of the rotating shaft 214 to rotate. Since the gear 215 meshes with the tooth groove 232 on the upper surface of the inner side of the track frame 230, the rotation of the gear 215 is converted into linear motion along the tooth groove 232, thereby pushing the sliding frame 220 connected to it to move within the track frame 230. The fixed angle bracket 213 ensures the stability of the motor within the drive frame 210, making the power transmission stable. In this way, the front and back adjustment of the seat 1 can be achieved through the rotation of the motor. The roller 224 rotatably connected inside the sliding frame 220... The middle part of 24 is lower than the two ends, so that when it rolls above the tooth groove 232, it can maintain a stable rolling state. The roller 224 also plays an auxiliary support role and can form a good fit with the tooth groove 232. The ball bearings 223 rotatably connected in the grooves 222 on both sides cooperate with the track frame 230 of the track mechanism 23. The roller 224 rolls in the track frame 230, so that the sliding frame 220 can move smoothly in the front and back direction. The ball bearings 223 in the grooves 222 on both sides roll at the corresponding positions in the track frame 230, reducing the lateral friction generated when the sliding frame 220 moves, ensuring the stability of the movement, and helping the seat 1 to move smoothly back and forth. In this way, the seat 1 can be accurately, smoothly and efficiently adjusted on the slide rail assembly 2.
