Abstract
Description
Technical Field
[0001] This utility model relates to the field of automobile manufacturing, specifically to a lightweight seat flat roller reinforcement mechanism. Background Technology
[0002] In the current automobile production process, in order to minimize the weight of the vehicle, various new lightweight materials are used in some in-vehicle equipment. These materials not only reduce the overall weight of the vehicle, but also maintain the comfort of the vehicle. For example, the seats are lightweight. In order to ensure the structural stability while making the seats lightweight, a reinforcement mechanism is usually added to the flat roller mechanism that moves the seats back and forth.
[0003] The existing lightweight seat flat roller reinforcement mechanism includes a pair of seat rails located under the seat and a roller mechanism located between the rails. The roller mechanism consists of multiple rollers, an L-shaped bracket connecting the rollers, and a supporting aluminum plate shell welded between the L-shaped brackets. To ensure the stability of the aluminum plate shell, the number of rollers in a single layer is usually two.
[0004] To ensure the stability of the rollers, the aluminum shell is generally made of all-aluminum honeycomb panel and welded to four L-shaped brackets. This ensures the stability of the rollers and the stability of the force between the seat and the rollers. However, when the seat moves, all the weight is distributed among the rollers. When people adjust the seat's fore-and-aft distance, they usually sit on the seat, which means that the rollers will bear the weight of the human body when sliding. This increases the friction between the rollers and the convex grooves. Once the lubricant is insufficient, hard friction will occur between the rollers and the grooves, thus accelerating the wear of the rollers. Utility Model Content
[0005] The technical problem this invention aims to solve is that the existing lightweight seat roller reinforcement mechanism lacks a force reduction mechanism, causing all the force above the seat to be applied to the roller, thus accelerating roller wear.
[0006] To solve the above-mentioned technical problems, the technical solution provided by this utility model is: a lightweight seat flat roller reinforcement mechanism, including two opposing seat tracks and a roller mechanism located between the seat tracks, wherein the seat track has a convex groove inside, and the opening end of the convex groove is located on the inner side of the seat track;
[0007] The roller mechanism includes several sets of rollers that are locked in the seat track, an L-shaped bracket located inside the rollers, and a supporting aluminum plate shell welded between the L-shaped brackets. The number of rollers on one side is multiple.
[0008] A magnetic levitation decompression assembly is provided above the seat track. The magnetic levitation decompression assembly includes a fixed unidirectional magnet attached to the top surface of the seat track, a buoyancy unidirectional magnet located on one side of the top surface of the L-shaped bracket, a buoyancy magnet fixing block welded to one side of the top surface of the L-shaped bracket, and a limiting rod passing through the buoyancy magnet fixing block. The through hole size of the limiting rod of the buoyancy magnet fixing block is slightly larger than the diameter of the limiting rod. A magnetic leakage prevention baffle is welded above the buoyancy magnet fixing block and fixed to the top surface of the seat track. The seat track is made of aluminum.
[0009] As an improvement, the interior of the aluminum plate shell has a honeycomb structure.
[0010] As an improvement, the buoyancy unidirectional magnet is attached to the bottom surface of the buoyancy magnet fixing block with strong adhesive.
[0011] As an improvement, the roller is connected to the L-shaped bracket via an antimagnetic bearing, and the outer wall end of the roller is provided with a rubber tire.
[0012] As an improvement, the front and rear ends of the seat track are provided with sealing plates that close the seat track slots, and the limiting rod passes through the sealing plates.
[0013] As an improvement, a positioning component for fixing the seat position is provided on one side of the aluminum plate shell. The positioning component includes a convex shaft passing through the left and right sides of the aluminum plate shell, a reset pressure spring sleeved on the convex shaft, a positioning rack welded to the top surface of the anti-leakage magnetic baffle, and an arc-shaped clamping plate welded to the left and right ends of the convex shaft.
[0014] The advantages of this invention compared with the prior art are as follows: This device generates magnetic levitation by fixing the relative magnetic fields of the unidirectional magnet and the buoyancy unidirectional magnet, thereby reducing the force on the roller. In addition, there is a limiting rod above the buoyancy unidirectional magnet to limit the upward movement of the buoyancy unidirectional magnet, which can ensure that the roller will not be suspended in the air, and ensure that the force on the roller is in a stable state. While reducing friction, it also ensures the stability of the suspension distance. Attached Figure Description

[0020] The present invention will now be described in further detail with reference to the accompanying drawings.
[0021] As per the instruction manual Figure 1 , 2 As shown in Figures 3 and 4, the system includes two opposing seat tracks 1 and a roller mechanism 2 located between the seat tracks 1. The seat track 1 has a convex groove inside, and the opening end of the convex groove is located inside the seat track 1.
[0022] The roller mechanism 2 includes several sets of rollers 21 that are locked in the seat track 1, an L-shaped bracket 22 located inside the rollers 21, and a supporting aluminum plate shell 23 welded between the L-shaped brackets 22. The number of rollers 21 on one side is multiple, and the number of rollers 21 on one side is usually two. The interior of the aluminum plate shell 23 is a honeycomb structure, that is, an all-aluminum honeycomb panel, which is not only lightweight, but also has high strength and high rigidity. The honeycomb structure provides excellent compressive and tensile strength, making the panel less prone to deformation under stress. In order to prevent the rollers 21 from directly contacting the bottom surface of the inner groove of the seat track 1 and to increase the rotation speed, the rollers 21 are connected to the L-shaped brackets 22 through anti-magnetic bearings, and the outer wall end of the rollers 21 is provided with rubber tires 211.
[0023] To reduce the pressure on the roller 21, a magnetic levitation pressure-reducing assembly 3 is provided above the seat track 1. The magnetic levitation pressure-reducing assembly 3 includes a fixed unidirectional magnet 31 adhered to the top surface of the seat track 1, a buoyancy unidirectional magnet 32 located on one side of the top surface of the L-shaped bracket 22, a buoyancy magnet fixing block 33 welded to one side of the top surface of the L-shaped bracket 22, and a limiting rod 34 passing through the buoyancy magnet fixing block 33. The through-hole size of the limiting rod 34 in the buoyancy magnet fixing block 33 is slightly larger than the diameter of the limiting rod 34, which can ensure that the buoyancy magnet fixing block 33 slides normally while also ensuring the buoyancy unidirectional magnet 32... The magnetic levitation system is in normal use and can reduce the pressure of the buoyancy magnetic fixing block 33 on the limiting rod 34. The buoyancy magnetic fixing block 33 is welded above a magnetic leakage prevention baffle 35 fixed to the top surface of the seat track 1. The seat track 1 is made of aluminum, which has a good magnetic isolation effect and can effectively prevent the fixed unidirectional magnet 31 and the buoyancy unidirectional magnet 32 from affecting the surrounding area. The fixed unidirectional magnet 31 and the buoyancy unidirectional magnet 32 have an effect similar to that of a magnetic levitation train, reducing the pressure on the roller 21 and thus ensuring that the wear of the rubber tire 211 is reduced when the roller 21 moves.
[0024] To facilitate seat positioning after adjustment, a positioning component 4 for fixing the seat position is provided on one side of the aluminum shell 23. The positioning component 4 includes a convex shaft 41 passing through the left and right sides of the aluminum shell 23, a reset pressure spring 42 sleeved on the convex shaft 41, a positioning rack 43 welded to the top surface of the anti-leakage magnetic baffle 35, and an arc-shaped locking plate 44 welded to the left and right ends of the convex shaft 41. The function of the positioning component 4 can be referenced to the wrench reset structure when adjusting the seat in an old vehicle. When the convex shaft 41 is pressed down, the arc-shaped locking plate 44 is lifted, causing the arc-shaped locking plate 44 to separate from the positioning rack 43, thereby allowing the roller 21 to move normally on the seat track 1.
[0025] In order to prevent the roller 21 from rolling out of the seat track 1 and to fix the beginning and end of the limiting rod 34, the front and rear ends of the seat track 1 are provided with a sealing plate 11 to close the slot of the seat track 1, and the limiting rod 34 passes through the sealing plate 11.
[0026] In a specific implementation of this invention, pressing the convex shaft 41 causes the arc-shaped clamping plate 44 to separate from the positioning rack 43. Then, the seat is moved, and the position of the seat is adjusted by the rolling roller 1. After the position is fixed, the convex shaft 41 is released, and the convex shaft 41 will be reset under the action of the reset pressure spring 42, thereby locking the position of the seat.
[0027] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
