[0004] The purpose of the utility model is to overcome the defects of the above-mentioned prior art and to provide a three-section slide rail mechanism and a car storage device suitable for a car storage box, which has a simple structure, stable structure, smooth sliding, light weight, easy production and economical cost.

[0005] The purpose of the utility model can be achieved through the following technical solutions:

[0006] On the one hand, the utility model provides a three-section slide rail mechanism suitable for a car storage box, which is used to connect between the storage box and the storage shell of the car. The three-section slide rail mechanism includes:

[0007] a first outer rail connected to the storage box;

[0008] a second outer rail connected to the storage housing;

[0009] an inner rail located between the first outer rail and the second outer rail;

[0010] a first ball bearing embedded between the first outer rail and the inner rail;

[0011] And a second ball is embedded between the second outer rail and the inner rail.

[0012] Furthermore, a first concave ball groove is provided on the inner side of the first outer rail, and a third concave ball groove is provided on the inner rail close to the first outer rail. The first ball rolls in the first concave ball groove and the third concave ball groove to realize sliding of the first outer rail and the inner rail.

[0013] Furthermore, the first balls are arranged in two rows, which are arranged side by side on the same horizontal plane of the first concave ball groove and the third concave ball groove.

[0014] Furthermore, a second concave ball groove is provided on the inner side of the second outer rail, and a fourth concave ball groove is provided on the side of the inner rail close to the second outer rail. The second ball rolls in the second concave ball groove and the fourth concave ball groove to realize the sliding of the second outer rail and the inner rail.

[0015] Furthermore, the second balls are arranged in two rows, which are arranged side by side on the same horizontal plane of the second concave ball groove and the fourth concave ball groove.

[0016] Furthermore, a plurality of first rivet holes are arranged in a transverse direction on the outer side of the first outer rail, and the first outer rail and the storage box are connected and fixed by passing first rivets through the first rivet holes.

[0017] Furthermore, a plurality of second rivet holes are arranged in a transverse direction on the outer side of the second outer rail, and second rivets are passed through the second rivet holes to connect and fix the second outer rail and the storage shell.

[0018] Further, the inner side wall of the first outer rail is provided with first limiting protrusions, which are located at both ends of the first rolling ball and limit the position of the first rolling ball, which is determined according to the length of the first rolling ball;

[0019] The inner side wall of the second outer rail is provided with second limiting protrusions, which are located at both ends of the second rolling ball and limit the position of the second rolling ball, which is determined according to the length of the second rolling ball;

[0021] Furthermore, before assembly, the first and second limiting convex points are not stamped, and the third limiting convex point is extruded in advance. After assembly, the first and second limiting convex points are stamped to obtain the first and second limiting convex points.

[0022] Furthermore, lubricating oil is used to lubricate the first outer rail, the first ball and the inner rail.

[0023] Furthermore, lubricating oil is used to lubricate the second outer rail, the second ball bearing and the inner rail.

[0025] Furthermore, the first outer rail, the second outer rail and the inner rail are formed by extrusion of aluminum alloy. Compared with conventional steel structure rolling, the arc surfaces of the first concave ball groove, the second concave ball groove, the third concave ball groove and the fourth concave ball groove formed therein are smoother when contacting the first ball or the second ball.

[0026] Furthermore, the first outer rail, the first ball, the inner rail, the second ball, and the second outer rail are assembled into a slide rail assembly by means of a slide rail assembly device, the first outer rail, the first ball, and the inner rail are lubricated with lubricating oil, and the second outer rail, the second ball, and the inner rail are lubricated with lubricating oil; after assembly, a stamping device is used to stamp the first limit protrusion, the second limit protrusion, and the third limit protrusion on the first outer rail, the second outer rail, and the inner rail, thereby obtaining a three-section slide rail mechanism suitable for a car storage box.

[0027] The method for using the three-section slide rail mechanism suitable for an automobile storage box of the utility model is as follows: the three-section slide rail mechanism of the automobile storage box adopts two groups, which are respectively connected to two sides of the automobile storage box. When assembling and using, firstly, the first outer rail of the three-section slide rail mechanism of the automobile storage box is fixed to the storage box by a first rivet; then, the second outer rail is riveted and fixed to two sides of the storage shell by a second rivet, so as to realize the assembly of the three-section slide rail mechanism suitable for the automobile storage box with the storage box and the storage shell.

[0028] This structure itself is more solid and reliable, the car installation is convenient and stable, and the drawer storage box can be fully pulled out, which is conducive to easier placement and search of items in daily use.

[0029] On the other hand, the utility model also provides a car storage device, which includes the above-mentioned three-section slide rail mechanism, and also includes a storage box and a storage shell of the car, and the three-section slide rail mechanism connects the storage box and the storage shell of the car.

[0030] Compared with the prior art, the utility model has the following advantages:

[0031] (1) The three-section slide rail mechanism of the utility model is formed by extrusion of aluminum alloy. Compared with conventional steel structure rolling, the arc surface of the first concave ball groove, the second concave ball groove, the third concave ball groove, and the fourth concave ball groove formed by the utility model is smoother when in contact with the first ball or the second ball. In addition, the riveting structure is simple, the manufacturing is convenient, and it can be mass-produced.

[0032] (2) The connection structure between the three-section slide rail mechanism and the automobile storage box of the utility model is firm and reliable, and the slide rail is easy to install, and the drawer storage box can be fully pulled out, which is conducive to easier placement and search of items in daily use.

[0033] (3) The three-section slide rail mechanism of the present invention is easy to install and disassemble. If any problem is found after installation, it can be easily disassembled and replaced.

[0034] (4) In the present invention, the first and second balls are not fixed by a ball fixing bracket, but are respectively arranged on the first concave ball groove of the first outer rail, the third concave ball groove of the inner rail, the second concave ball groove of the second outer rail, and the fourth concave ball groove of the inner rail, that is, the balls are arranged in the concave ball groove between the inner and outer rails, so as to improve the smoothness during use. Since the ball fixing bracket assembly has a fixed structure, the distance between the balls is wide and the gap is large, so that the number of balls is small, and the friction between the balls and the ball fixing bracket is increased, so that the smoothness is poor; in the absence of the ball fixing bracket assembly, the balls are densely distributed, and the number of balls will be significantly more than the number of balls in the presence of the ball fixing bracket assembly, so that it will slide more smoothly, with higher smoothness, and enhance the user experience.

[0035] (6) The three-section slide rail mechanism of the utility model is light in weight and can be applied to automobile storage box slide rails that require lighter weight, and has a wider range of applications. BRIEF DESCRIPTION OF THE DRAWINGS
