DETAILED DESCRIPTION

[0022] 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 conjunction 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.

[0023] The automobile slide rail mechanism is used for a sliding automobile auxiliary instrument panel to realize the sliding setting of the auxiliary instrument panel.

[0024] Reference Figure 1 , Figure 2 and Figure 3 In some embodiments, the vehicle slide rail mechanism includes: 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 lower rail.

[0025] The upper rail 20 has two sets of sliding parts arranged side by side, and the sliding parts are arranged along the length direction of the track groove. The sliding parts are respectively arranged in the track groove 101 and slide with the track grooves. The sliding parts include a plurality of sliding brackets 201 arranged at intervals, and the sliding brackets 201 are rotatably provided with lower rollers 202, and the lower rollers 202 roll with the bottom surface of the track groove. At this time, the upper rail and the lower rail form a rolling fit connection through the lower rollers arranged on the plurality of sliding brackets, which facilitates the sliding of the auxiliary instrument panel of the automobile.

[0026] A shock absorbing assembly 30 is disposed on the sliding bracket 201, referring to Figure 4 , Figure 5 and Figure 6The 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 and roll with the top of the track groove.

[0027] The bottom surface of the track groove 101 here refers to the lower surface in the closed groove structure, and the top of the track groove 101 refers to the upper surface in the closed groove structure. A notch 103 for the sliding bracket to extend out is provided on the lower rail at a position corresponding to the track groove, and sealing strips 104 are provided on both sides of the notch 103 to seal the notch to prevent debris from falling into the track groove.

[0028] A shock absorbing component is arranged 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, which can well 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, and can well ensure the installation matching stiffness of the upper rail on the lower rail, and ensure the stability and smoothness of the sliding of the automobile auxiliary instrument panel.

[0029] 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 conveniently connected to the hanging holes and the hanging shaft, making the connection and installation of the tension spring convenient.

[0030] In some embodiments, a limiting surface 102 matching 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 forces to the upper roller in the vertical and horizontal directions.

[0031] 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 forces are in opposite directions, 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.

[0032] 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.

[0033] 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.

[0034] A wheel axle 304 is arranged on the shock absorbing bracket 301 , and an upper roller 303 is arranged at one end of the wheel axle 304 and outside the shock absorbing bracket.

[0035] The lower roller and the upper roller both use miniature deep groove ball bearings and a POM plastic-coated structure on the outside. They have self-lubrication and excellent noise reduction properties, can effectively reduce sliding noise and friction, can well ensure the NVH performance of the slide mechanism, and improve the quality of the slide mechanism.

[0036] In some embodiments, the upper roller 303 is disposed between the two connection positions of the shock absorbing bracket 301 and the sliding bracket 201, and the upper roller 303 is disposed close to the side where the shock absorbing bracket and the sliding bracket are rotatably connected. At this time, the shock absorbing bracket forms a lever structure, which can increase the magnitude of the force exerted by the elastic force of the elastic member on the upper roller and the track groove. For example, the position of the upper roller is set so that the ratio between the force arm of the elastic force and the force arm of the upper roller is 4:1, so that the use of a tension spring with a smaller elastic coefficient can meet the floating stiffness requirements between the upper rail and the lower rail.

[0037] In some embodiments, a notch 204 for setting a shock-absorbing bracket is provided between the two lower rollers on the sliding bracket 201, and the shock-absorbing bracket 301 is arranged in the position of the notch. The shock-absorbing bracket is arranged at the notch position to increase the distance between the shock-absorbing bracket and the lower rail bracket, facilitate the arrangement of the shock-absorbing bracket and avoid interference between the shock-absorbing bracket and the lower rail during use.

[0038] In some embodiments, the shock absorbing bracket 301 is configured as a groove structure, and the inner walls on both sides of the shock absorbing bracket 301 are respectively arranged opposite to the outer walls on both sides of the sliding bracket 201. At this time, the wall panels on both sides of the shock absorbing bracket 201 are respectively covered and arranged on the outside of the sliding bracket 201, and the distance between the wall panels on both sides 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 in the width direction, the movement of the shock absorbing bracket in the width direction is limited, the stability of the shock absorbing bracket installed on the sliding bracket is ensured, and the stability and reliability of the performance of the shock absorbing component are ensured.

[0039] The present invention also relates to a vehicle auxiliary instrument panel module. In some embodiments, the vehicle auxiliary instrument panel module includes: Secondary instrument panel; And the automobile slide rail mechanism, the auxiliary instrument panel is arranged on the upper rail 20 of the automobile slide rail mechanism.
