[0023] The preferred embodiments of the present invention are given below in conjunction with the accompanying drawings and described in detail.

[0024] like Figure 1As shown, the center console sliding structure according to the first preferred embodiment of the present invention includes an upper rail 1, a lower rail 2, a rack 3 and a driving mechanism 4, wherein the upper rail 1 is movably mounted on the lower rail 2, the rack 3 is fixedly connected to the lower rail 2, and the driving mechanism 4 is fixedly connected to the upper rail 3 and connected to the rack 3 to realize relative movement and locking of the upper rail 1 and the lower rail 2.

[0025] like Figure 2 As shown, the rack 3 is an integrated plastic rack, which is a first semi-enclosed structure and has an exposed arc-shaped tooth 31 and upper and lower tooth windows 32 arranged at opposite ends of the arc-shaped tooth 31. In this embodiment, the arc-shaped tooth 31 is arranged on the side of the rack 3, and the upper and lower tooth windows 32 are thin plate structures arranged at the upper and lower ends of the rack 3, and a plurality of rectangular grooves are opened thereon to support the driving mechanism 4.

[0026] like Figure 3 As shown, the driving mechanism 4 includes a housing 41, a first gear 42, a second gear 43, a flexible shaft 44 and a motor 45, wherein the housing 41 is fixedly connected to the lower side of the upper rail 1 by bolts, the meshing first gear 42 and the second gear 43 are rotatably mounted on the housing 41 to form a gear box, the motor 45 is fixedly connected to the upper side of the upper rail 1 by bolts and connected to the gear box through the flexible shaft 44, and the second gear 43 has an external thread 431 meshing with the rack 3 (see Figure 2 ), in this way, the motor 45 drives the second gear 43 through the flexible shaft 44, and the second gear 43 meshes with the arc-shaped teeth 31 of the rack 3 to realize transmission. It should be understood that the specific structure of the driving mechanism 4 here is only an example and not a limitation, and other structures installed on the upper rail 1 that can drive the rack 3 can be used here. It should be understood that the second gear 43 is clearance-matched with the upper and lower tooth windows 32 of the rack 3.

[0027] In this embodiment, the housing 41 is a second semi-enclosed structure, and the outer thread 431 of the second gear 43 rotatably mounted on the second semi-enclosed structure has a lateral exposed portion, which is accommodated in the first semi-enclosed structure of the rack 3 and cooperates with the arc-shaped tooth 31, such as Figure 4 As shown. In this embodiment, the lateral exposed portion accounts for, for example, one-third of the external thread 431, which can reduce the noise of its meshing with the rack 3. In addition, the lead of the rack 3 can be adjusted as needed. For example, by increasing the lead, the speed of the second gear can be reduced, thereby reducing noise. It should be understood that under the premise of a fixed central control speed, increasing the rack lead will reduce the speed of all gears, optimize each level of sound, and perform better for the entire central control sound. In particular, the rack 3 is a full plastic structure, and the noise can be further reduced by plastic parts.

[0028] In this embodiment, the front and rear ends of the rack 3 are fixed to the lower rail 2 by means of embedded nuts and bolts. Figure 4As shown, the nut 33 is pre-embedded in the rack 3, and the bolt passes through the hole on the lower rail 2 and is screwed into the nut 33 to achieve connection. In a variation of this embodiment, the front and rear ends of the rack 3 are fixed to the lower rail 2 by bolt and nut connection. Specifically, the bolt passes through the lower rail 2 and the rack 3 from one side, and the nut is tightened with the bolt on the other side to achieve connection. In another variation of this embodiment, the front and rear ends of the rack 3 are fixed to the lower rail 2 by tapping. Specifically, the self-tapping screw drills a hole on the lower rail 2 and the rack 3 without pre-processed screw holes and taps out a matching female thread, completing drilling, tapping, fixing and locking connection at one time.

[0029] The center console sliding structure according to the second preferred embodiment of the present invention is different from the center console sliding structure of the first preferred embodiment only in the rack 3a, such as Figure 5 and Figure 6 As shown, it is a plastic-coated metal rack, which is formed by coating a plastic layer 311a on a metal part 312a, wherein the plastic layer 311a provides an inwardly concave arc-shaped tooth 31a, whose tooth surface meshes with the second gear 43 to ensure the silencing effect, and the metal part 312a provides upper and lower tooth windows 32a, thereby improving the strength through metal, which is suitable for heavy-load long-stroke transmission and locking scenarios. In this embodiment, the metal part 312a is an integrated metal stamping part, and the plastic layer 311a is coated on the metal part 312a.

[0030] In this embodiment, the front and rear ends of the rack 3a are fixed to the lower rail 2 by projection welding nuts and bolts. Figure 7 As shown, the nut 33a is pre-projection welded to the rack 3, and the bolt is screwed into the nut 33a through the hole on the lower rail 2 to achieve connection. It should be understood that the projection welding connection method here is only an example and not a limitation, and the embedded nut bolt connection, bolt and nut butt connection, and self-tapping screw tapping connection mentioned in the first preferred embodiment can all be used here.

[0031] The center console sliding structure according to the third preferred embodiment of the present invention differs from the center console sliding structure of the second preferred embodiment only in the rack 3b, as shown in FIG. Figure 8 and Fig. 9 As shown, it is a plastic clamped metal rack, which is formed by clamping a plastic layer 311b on a metal part 312b, wherein the plastic layer 311b provides concave arc-shaped teeth 31b and upper and lower tooth windows 32b. Specifically, the metal part 312b is a U-shaped part, and the plastic layer 311b is clamped on opposite sides of the metal part 312b, which is low in cost and easy to install, and is suitable for short-stroke transmission and locking scenarios.

[0032] The above is only a preferred embodiment of the present invention, and is not intended to limit the scope of the present invention. The above embodiment of the present invention can also be modified in various ways. That is, all simple, equivalent changes and modifications made according to the claims and the description of the present invention fall within the scope of protection of the claims of the present invention. The contents not described in detail in the present invention are all conventional technical contents.
