[0032] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in combination with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments.

[0033] The automobile slide rail mechanism is used for a sliding automobile auxiliary instrument panel to realize the sliding setting of the auxiliary instrument panel.

[0034] Reference Figure 1 、 Figure 2 and Figure 3 In some embodiments, the vehicle slide mechanism includes:

[0035] The lower rail 10 has two sets of track grooves arranged side by side, and the track grooves are in a closed groove structure. Figure 1 The interior of the lower rail is set to a hollow structure, and two independent rail grooves are formed near the two sides of the interior of the lower rail.

[0036] The upper rail 20 has two sets of sliding members arranged side by side, extending along the length of the track groove. Each sliding member fits within the track groove 101 and slides therewith. The sliding members comprise a plurality of spaced-apart sliding brackets 201, each rotatably supported by lower rollers 202 that roll against the bottom surface of the track groove. The lower rollers on the sliding brackets create a rolling connection between the upper and lower rails, facilitating the sliding of the vehicle's auxiliary instrument panel.

[0037] A shock absorbing component 30 is provided on the sliding bracket 201. Figure 4 、 Figure 5 and Figure 6 The shock-absorbing assembly 30 includes a shock-absorbing bracket 301, which is rotatably connected to the sliding bracket 201 at one end and connected to the sliding bracket 201 at the other end through an elastic member 302. An upper roller 303 is rotatably provided on the shock-absorbing bracket, and under the action of the elastic member, the upper roller can contact the top of the track groove and roll with the top of the track groove.

[0038] The bottom surface of the track groove 101 here refers to the lower surface within the closed groove structure, and the top of the track groove 101 refers to the upper surface within the closed groove structure. The lower rail has a slot 103 corresponding to the track groove, through which the sliding bracket extends. Sealing strips 104 are provided on both sides of slot 103 to seal the slot and prevent debris from falling into the track groove.

[0039] A shock-absorbing component is provided on the sliding bracket of the automobile slide rail mechanism, so that a floating matching structure is formed between the upper rail and the lower rail. This can effectively solve the problem that the upper rail is not stable when moving on the lower rail or even gets stuck due to manufacturing and assembly errors or debris falling into the track groove between the upper rail and the lower rail. In addition, the installation matching rigidity of the upper rail on the lower rail is well guaranteed, and the stability and smoothness of the sliding of the automobile auxiliary instrument panel are guaranteed.

[0040] The elastic member 302 can be a tension spring, one end of which is connected to a hanging hole provided on the shock absorbing bracket, and the other end is connected to a hanging shaft 203 provided on the sliding bracket 201. Hooks are provided at both ends of the tension spring, and the hooks at both ends of the tension spring can be easily connected to the hanging holes and the hanging shaft, making the connection and installation of the tension spring convenient.

[0041] In some embodiments, a limiting surface 102 that matches the outer contour of the upper roller is provided at the top of the track groove where the upper roller rolls, so that the limiting surface 102 can apply force to the upper roller in the vertical and horizontal directions.

[0042] The upper rollers and the track grooves interact with each other in the vertical and horizontal directions. The upper rollers on the multiple sets of sliding parts and the corresponding limiting surfaces generate forces in the horizontal direction, and the directions of the forces are opposite, thereby limiting the installation position of the upper rail on the lower rail in the horizontal direction, ensuring the stability of the installation fit between the upper rail and the lower rail, and reducing the requirements for assembly accuracy between the upper rail and the lower rail.

[0043] In some embodiments, the outer contour of the upper roller and the limiting surface 102 are matched arc-shaped surfaces, so that a good limiting fit can be formed between the upper roller and the limiting surface, while reducing the friction between the two.

[0044] In some embodiments, on the same sliding bracket, the lower roller 202 and the upper roller 303 are respectively arranged on both sides of the sliding bracket 201. Through the cooperation formed between multiple sets of sliding parts and track grooves at multiple positions, a stable installation cooperation structure is formed between the upper rail and the lower rail.

[0045] A wheel axle 304 is provided on the shock absorbing bracket 301 , and an upper roller 303 is provided at one end of the wheel axle 304 outside the shock absorbing bracket.

[0046] Both the lower and upper rollers use miniature deep groove ball bearings and a POM plastic-coated structure on the outside. They have self-lubrication and excellent noise reduction properties, which can effectively reduce sliding noise and friction, and can well ensure the NVH performance of the slide mechanism, thereby improving the quality of the slide mechanism.

[0047] In some embodiments, the upper roller 303 is positioned between the two connection points of the shock-absorbing bracket 301 and the sliding bracket 201, and is positioned near the side where the shock-absorbing bracket and the sliding bracket are pivotally connected. In this case, the shock-absorbing bracket forms a lever structure, which can increase the force exerted by the elastic member on the upper roller and the track groove. For example, the upper roller is positioned so that the ratio of the elastic force arm to the upper roller arm is 4:1. In this way, a tension spring with a smaller elastic coefficient can meet the required floating stiffness between the upper and lower rails.

[0048] In some embodiments, a notch 204 for arranging a shock-absorbing bracket is provided on the sliding bracket 201 between the two lower rollers, and the shock-absorbing bracket 301 is arranged in the notch. Arranging the shock-absorbing bracket in the notch increases the distance between the shock-absorbing bracket and the lower rail bracket, facilitating the installation of the shock-absorbing bracket and preventing interference between the shock-absorbing bracket and the lower rail during use.

[0049] In some embodiments, the shock-absorbing bracket 301 is configured as a groove-shaped structure, with the inner walls of the shock-absorbing bracket 301 facing the outer walls of the sliding bracket 201. In this case, the side panels of the shock-absorbing bracket 201 are respectively arranged to cover the outer side of the sliding bracket 201. The spacing between the side panels of the shock-absorbing bracket can be set to be equal to the width of the sliding bracket. Through the limited fit between the two side panels in the width direction, the movement of the shock-absorbing bracket in the width direction is restricted, ensuring the stability of the shock-absorbing bracket installed on the sliding bracket, and ensuring the stability and reliability of the performance of the shock-absorbing assembly.

[0050] The present invention also relates to a vehicle auxiliary instrument panel module. In some embodiments, the vehicle auxiliary instrument panel module includes:

[0051] auxiliary instrument panel;

[0052] And the automobile slide rail mechanism, the auxiliary instrument panel is arranged on the upper rail 20 of the automobile slide rail mechanism.
