Description

Technical Field

[0001] This utility model relates to the field of automotive seat technology, and in particular to an auxiliary sliding structure for automotive seat drawers. Background Technology

[0002] In car seat design, drawer structures are often used to store small items such as mobile phones, wallets, and glasses, providing convenience for passengers. Traditional car seat drawer sliding mechanisms typically use metal slide rails to achieve the drawer's sliding function. However, with the continuous development of lightweight automotive design concepts, traditional metal slide rails, due to their heavy weight, are gradually failing to meet the demands of modern automobiles for lightweight and high efficiency.

[0003] While metal drawer slides offer high strength and wear resistance, their relatively high manufacturing cost and weight hinder lightweight design of the entire vehicle. Furthermore, the material properties of metal slides often generate significant friction during sliding, increasing the force required to use the drawer and potentially causing uneven sliding, wobbling, or jamming, thus impacting the user experience. To overcome these drawbacks, it's necessary to find a lighter, more wear-resistant alternative material with better sliding performance. Plastic, as a lightweight and easily processed material, has gradually entered the design landscape for drawer slides. However, while plastic slides are lightweight, their relatively high friction can lead to uneven drawer sliding and even damage to both the slides and the drawer itself. Therefore, how to reduce friction and improve the smoothness and stability of drawer sliding while maintaining the lightweight advantage of plastic slides has become a pressing issue in the design of automotive seat drawer sliding mechanisms. Utility Model Content

[0004] In view of the problems existing in the prior art, the present invention aims to provide a sliding structure for car seat drawers, which can improve the smoothness and stability of drawer sliding while realizing the lightweight design of the seat, and extend the service life of the drawer and slide rail.

[0005] To achieve the above objectives, this utility model proposes a sliding structure for a car seat drawer, including a drawer body and slide rails arranged opposite each other on both sides of the drawer body. Both the drawer body and the slide rails are made of plastic. The drawer body has a sliding groove extending forward and backward at the position corresponding to the slide rail. The slide rail is fixed to the seat frame and extends into the sliding groove and slides in a sliding connection with the sliding groove. Several rollers are located between the slide rail and the sliding groove. When the slide rail slides relative to the sliding groove, the rollers can roll relative to the sliding groove, thereby reducing the friction between the drawer body and the slide rail.

[0006] In the above scheme: a bridge bracket is fixed between the two side slide rails, the drawer body is supported on the bridge bracket, and a guide mechanism for guiding the drawer body forward and backward is provided between the drawer body and the bridge bracket.

[0007] The bridge support firmly connects the two side rails together, forming a stable support structure. The drawer body is supported on the bridge support, increasing the stability of the drawer body during sliding and preventing drawer wobbling caused by deformation or loosening of the rails. The guide mechanism design further ensures the front-to-back guiding accuracy of the drawer body during sliding, reducing vibration and noise generated during the sliding process.

[0008] In the above solution: the guiding mechanism includes a guiding protrusion located at the bottom of the drawer body and a guiding groove located on the bridge bracket. The guiding protrusion and the guiding groove are slidably engaged, resulting in a simple structure and convenient processing.

[0009] In the above scheme: the roller is rotatably mounted on the top of the slide rail and keeps in contact with the upper side wall of the slide groove. The roller is directly mounted on the slide rail, which is convenient for assembly.

[0010] In the above solution: the top of the slide rail is equipped with three sets of rollers spaced apart along the front-to-back direction. The design of the three sets of rollers can ensure that the drawer body remains stable during the sliding process.

[0011] In the above scheme: the roller center is provided with a rotating shaft along both sides, the rotating shaft and the roller are integrally injection molded, and the roller is clamped on the slide rail through the rotating shaft. The integral injection molding process is convenient.

[0012] In the above scheme: the rotating shaft is secured to the slide rail by an inverted structure, and a gap is left between the inverted structure and the slide rail for the rotating shaft to rotate. The structure is simple and easy to install.

[0013] In the above scheme, the roller is made of a self-lubricating material, such as PUM, which further reduces friction and improves sliding performance.

[0014] The beneficial effects of this utility model are:

[0015] 1. Replacing traditional metal drawer slides with plastic ones facilitates a lighter seat design. 2. To avoid excessive friction from plastic slides, rollers are installed on the drawer body to roll relative to the slide rails. This rolling friction significantly reduces the friction between the drawer body and the slide rails compared to traditional sliding friction. This not only makes the drawer slide smoother and reduces the pushing force required by the user, but also improves the stability and consistency of the drawer's sliding, preventing excessive wobbling. 3. The rollers' aiding effect also effectively extends the lifespan of the drawer and slide rails. Due to reduced friction, the wear rate of the slide rails and tracks is correspondingly slower.

[0019] Figure 3 This is an assembly diagram of the drawer body and the slide rails. Detailed Implementation

[0020] like Figure 1 As shown in Figure 3, a sliding structure for a car seat drawer mainly consists of a drawer body 1 and slide rails 2 arranged on both sides of the drawer body 1.

[0021] Both the drawer body 1 and the slide rail 2 are made of plastic. The drawer body 1 has a sliding groove 3 extending forward and backward at the position corresponding to the slide rail 2. The slide rail 2 is fixed to the seat frame and extends into the sliding groove 3, slidingly connecting with the sliding groove 3. Several rollers 4 are located between the slide rail 2 and the sliding groove 3. When the slide rail 2 slides relative to the sliding groove 3, the rollers 4 can roll relative to the sliding groove 3, thereby reducing the friction between the drawer body 1 and the slide rail 2.

[0022] Ideally, a bridge bracket 5 is fixed between the two side slide rails 2, the drawer body 1 is supported on the bridge bracket 5, and a guide mechanism for guiding the drawer body 1 forward and backward is provided between the drawer body 1 and the bridge bracket 5.

[0023] The bridge bracket 5 firmly connects the two side slide rails 2 together, forming a stable support structure. The drawer body 1 is supported on the bridge bracket 5, which increases the stability of the drawer body 1 during sliding and prevents the drawer from shaking due to deformation or loosening of the slide rails 2. The design of the guide mechanism further ensures the front and rear guiding accuracy of the drawer body 1 during sliding, reducing the vibration and noise generated by the drawer body 1 during sliding.

[0024] Ideally, the guiding mechanism includes a guide protrusion located at the bottom of the drawer body 1 and a guide groove 6 located on the bridge bracket 5. The guide protrusion and the guide groove 6 slide together, resulting in a simple structure and easy processing.

[0025] Ideally, the roller 4 is rotatably mounted on the top of the slide rail 2 and keeps in contact with the upper side wall of the slide groove 3. The roller 4 is directly mounted on the slide rail 2, which is convenient for assembly.

[0026] Ideally, the top of the slide rail 2 should have three sets of rollers 4 spaced apart along the front-to-back direction. The design of the three sets of rollers 4 can ensure that the drawer body 1 remains stable during the sliding process.

[0027] Ideally, the roller 4 has a rotating shaft 41 at its center along both sides. The rotating shaft 41 and the roller 4 are integrally injection molded. The roller 4 is secured to the slide rail 2 by the rotating shaft 41. The integral injection molding process is convenient.

[0028] Ideally, the rotating shaft 41 is secured to the slide rail 2 by an inverted structure, and a gap is left between the inverted structure and the slide rail 2 for the rotating shaft 41 to rotate. The structure is simple and easy to install.

[0029] Ideally, roller 4 should be made of a self-lubricating material, such as PUM, to further reduce friction and improve sliding performance.
