[0002] With the development of automobile intelligence and the continuous improvement of users' pursuit of comfort, the demand for the adjustable travel of the steering column in the automobile development process has increased from the conventional up-and-down adjustable travel of about 30 mm to 90 mm or even larger up to 120 mm. However, there is currently no good shielding effect and no way to make the column sheath match well with the surrounding decorative parts during the over-long adjustable travel process. Summary of the Utility Model
[0003] To solve the above problems existing in the prior art, the utility model provides a multi-linkage rotary shielding structure for an over-long adjustable travel column sheath, which realizes the main body shielding action through the relative movement of the cover assembly and the upper shroud assembly, so that the column sheath matches well with the surrounding decorative parts.
[0004] To achieve the above object, the utility model provides the following technical solution: A multi-linkage rotary shielding structure for an over-long adjustable travel column sheath, including a guide block, a cover assembly, an upper shroud assembly and a lower shroud assembly. The upper shroud assembly and the lower shroud assembly are respectively located on the upper and lower surfaces of the column and wrap the column. The front ends of the upper shroud assembly and the lower shroud assembly are connected with a steering wheel. The cover assembly is located above the upper shroud assembly, and the front part of the cover assembly fits and overlaps on the rear surface of the upper shroud assembly. The guide block is located behind the cover assembly and fixed on the column. A hinge support is arranged on the upper surface of the rear part of the cover assembly, and a matching decorative plate is arranged above the rear part of the cover assembly to cover the hinge support. When the steering wheel moves downward along the column, the cover assembly rotates around the hinge support. The upper shroud assembly is provided with a first base and a second base. The first base and the second base are connected and fixed on the front part and the rear part of the upper shroud assembly respectively. When the steering wheel continues to move downward, after the upper shroud assembly contacts the guide block and under the guiding action of the guide block, the rear part of the upper shroud assembly rotates and flips upward around the first base driven by the second base, increasing the downward movement stroke of the steering wheel. During the downward movement of the steering wheel, the front part of the cover assembly always sequentially fits and slides upward on the surfaces of the upper shroud assembly and the steering wheel to shield the internal structure of the column.
[0005] Further, the cover assembly further includes a first rotating shaft, a rotating cover, two torsion springs and a sponge strip. The two torsion springs are sleeved on the front part of the hinge support. The front part of the hinge support, the torsion springs thereon and the upper side of the rear part of the rotating cover are movably connected through the first rotating shaft. The sponge strip is located below the front side of the rotating cover.
[0006] Further, the hinge support is fixed on the instrument panel skeleton.
[0007] Further, the upper shroud assembly further includes a second rotating shaft, an upper shroud flip cover, an upper shroud body, and two torsion springs. The second base is fixed to the lower front side of the upper shroud flip cover, the first base is fixed to the lower side of the upper shroud body, the two torsion springs are sleeved on the front side of the second base, and the front side of the second base and the torsion springs thereon are movably connected to the rear side of the first base through the second rotating shaft.
[0008] Further, the front part of the upper shroud body is arranged as a convex surface, and the first base is fixed to the lower rear part of the convex surface.
[0009] Further, when the steering wheel moves upward along the column, the rotating cover also sequentially slides along the steering wheel, the convex surface, and the upper shroud flip cover in a fitting manner.
[0010] Further, the guide block is provided with a guide surface that slopes upward to the rear.
[0011] Compared with the prior art, the beneficial effects of the present utility model are as follows:
[0012] 1. The structure of the present utility model is ingenious. The cover assembly matches the sizes of the upper shroud assembly and the steering wheel. The cover assembly can cover the upper surfaces of the upper shroud assembly and the steering wheel, and the cover assembly can slide on the surfaces of the upper shroud assembly and the steering wheel. At the same time, the cooperation between the rotating cover and the hinge support enables the rotating cover to rotate around the hinge support. The settings of the guide block, the first base, the second base, the upper shroud flip cover, and the upper shroud body enable the second base to drive the upper shroud flip cover to rotate around the first base together, thereby realizing the up-and-down sliding and up-and-down rotation adjustment of the ultra-long column.
[0013] 2. The present utility model is provided with a coil spring in the cover assembly, so that the cover assembly fits with the upper shroud assembly and the steering wheel during the sliding process; a torsion spring is provided in the upper shroud assembly, so that the upper shroud flip cover always fits with the guide block during rotation. When the upper shroud flip cover disengages from the guide block, under the action of the torsion spring, it fits with both sides of the lower shroud assembly; during the up-and-down sliding adjustment and up-and-down rotation adjustment processes, it can ensure that there are no any holes around the column sheath from beginning to end, and no internal structure can be seen from the upper line of sight, thereby achieving good aesthetics.

[0025] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts fall within the scope of protection of the present utility model.
[0026] Please refer to Figures 1-11, the present utility model provides the following technical solutions: an ultra-long adjustment stroke pipe column sheath multi-linkage rotary shielding structure, including a guide block 1, a cover assembly, an upper shield assembly, and a lower shield assembly 10. The upper shield assembly and the lower shield assembly 10 are respectively located on the upper and lower surfaces of the pipe column and wrap the pipe column. The front ends of the upper shield assembly and the lower shield assembly 10 are connected to a steering wheel 11. The dimensions of the connection between the upper shield assembly and the lower shield assembly 10 after combination are the same as those of the steering wheel 11. The cover assembly is located above the upper shield assembly, and the front part of the cover assembly fits and overlaps on the rear surface of the upper shield assembly. The guide block 1 is located behind the cover assembly and fixed on the pipe column. A hinge support 2 is provided on the upper surface of the rear part of the cover assembly. A matching decorative plate 12 is provided above the rear part of the cover assembly, and the decorative plate 12 covers the hinge support 2. The decorative plate 12 covers both the hinge support 2 and the internal structure of the instrument panel. What is exposed is the sheath with a protection function and the decorative part with a decorative function, covering the internal structure of the instrument panel and the pipe column, having a good shielding effect. When the steering wheel 11 moves downward along the pipe column, the cover assembly rotates around the hinge support 2, and the front part of the cover assembly fits and slides upward on the surface of the upper shield assembly. At this time, there is no gap between the cover assembly and the surface of the upper shield assembly, and the internal structure can be well shielded. A base one 7 and a base two 6 are provided on the upper shield assembly. The base one 7 and the base two 6 are connected and respectively fixed to the front and rear parts of the upper shield assembly. When the steering wheel 11 continues to move downward, after the upper shield assembly contacts the guide block 1 and under the guiding action of the guide block 1, the rear part of the upper shield assembly rotates and flips upward around the base one 7 driven by the base two 6. At this time, the front part of the cover assembly has already slid upward and fit on the front part of the upper shield assembly. At this time, the rear part of the upper shield assembly is covered by the cover assembly after moving downward together with the steering wheel 11. Then the front part of the cover assembly continues to slide upward and fit on the steering wheel 11. This process converts the axial space requirement into the up and down direction, increasing the downward movement stroke of the steering wheel 11. During the downward movement of the steering wheel 11, the front part of the cover assembly always sequentially fits and slides upward on the surfaces of the upper shield assembly and the steering wheel 11, shielding the internal pipe column structure.
[0027] Specifically, the cover assembly further includes a rotating shaft one 3, a rotating cover 4, two coil springs 13, and a sponge strip 14. The two coil springs 13 are sleeved on the front part of the hinge support 2. The front part of the hinge support 2, the coil springs 13 thereon, and the upper side of the rear part of the rotating cover 4 are movably connected through the rotating shaft one 3. The sponge strip 14 is located below the front side of the rotating cover 4.
[0028] Specifically, bumps 401 are provided on both sides of the rear part of the rotary cover 4. On the side edges of the hinge support 2, there are two connecting shafts 201 adapted to the bumps 401. On both sides of the connecting shaft 201 on the hinge support 2, there are also spring seats 202. The coil spring 13 is located in the bump 401 and abuts against the spring seat 202 at the same time. The coil spring 13 makes the rotary cover 4 fit against the upper shroud assembly and the surface of the steering wheel 11 in sequence during the upward sliding process. The connecting shaft 201 on the hinge support 2 passes through the bump 401 and the coil spring 13, and then passes through the two sides of the bump 401, the coil spring 13 and the connecting shaft 201 through the rotating shaft 3, thus connecting the hinge support 2 with the rotary cover 4. The hinge support 2 is screwed to the instrument panel skeleton.
[0029] Specifically, the upper shroud assembly further includes a rotating shaft 5, an upper shroud flip cover 8, an upper shroud body 9 and two torsion springs 15. The base 6 is fixed to the lower front side of the upper shroud flip cover 8, and the base 7 is fixed to the lower side of the upper shroud body 9. The two torsion springs 15 are sleeved on the front side of the base 6. The front side of the base 6 and the torsion springs 15 thereon are movably connected to the rear side of the base 7 through the rotating shaft 5. The front part of the upper shroud body 9 is set as a convex surface 901, and the base 7 is fixed to the lower rear part of the convex surface 901.
[0030] Specifically, a clamping groove block 602 is provided in the middle of the side of the base 6. On both sides of the clamping groove block 602, there are connecting shafts 601. The torsion spring 15 is sleeved on the connecting shaft 601. The middle of the side of the base 7 is stuck in the clamping groove block 602. The rotating shaft 5 passes through the side of the base 7, one side of the connecting shaft 601 and the torsion spring 15 thereon, the clamping groove block 602 and the middle of the base 7 therein, the connecting shaft 601 on the other side and the torsion spring 15 thereon, and the other side of the base 7 in sequence, thus connecting the base 6 and the base 7, and also connecting the upper shroud flip cover 8 and the upper shroud body 9. Moreover, the surface arc dimensions of the upper shroud flip cover 8 and the convex surface 901 on the upper shroud body 9 are the same, and under the action of the torsion spring 15, the upper shroud flip cover 8 is seamlessly connected with the convex surface 901 completely, and the upper shroud assembly fits against the lower shroud assembly 10, making the sheath outside the column more beautiful.
[0031] Specifically, the rotary cover 4 on the cover assembly overlaps on the upper shroud flip cover 8. When the steering wheel 11 moves downward along the column, the rotary cover 4 fits and slides along the upper shroud flip cover 8, the convex surface 901 and the steering wheel 11 in sequence. When the steering wheel 11 moves upward along the column, the rotary cover 4 also fits and slides along the steering wheel 11, the convex surface 901 and the upper shroud flip cover 8 in sequence, well shielding the internal column structure.
[0032] Specifically, a guiding surface 101 that slopes upward to the rear is provided on the guiding block 1. When the guiding block 1 contacts the upper shroud flap 8, under the guiding action of the guiding surface 101, since the upper shroud body 9 is fixed to the steering wheel 11, the upper shroud flap 8 rotates upward around the base one 7 on the upper shroud body 9 driven by the base two 6, further increasing the downward movement stroke of the steering wheel 11.
[0033] Specifically, the maximum downward movement distance of the steering wheel 11 reaches 120 mm.
[0034] Specifically, during the entire downward movement process, the pitching and rotation adjustment of the column can also be synchronously realized.
[0035] The movement process of the present utility model is as follows: As Figure 5 , in the initial state, the decorative plate 12 covers the convex block and the hinge support 2 on the rotating cover 4. The rotating cover 4 fits and overlaps on the upper shroud flap 8 and covers the rear part of the upper shroud flap 8. The upper shroud flap 8 is seamlessly connected to the convex surface 901 on the upper shroud body 9 under the action of the torsion spring 15. The upper shroud assembly and the lower shroud assembly 10 are in contact with each other on both sides and wrap the column; As Figure 8 , during the process of the steering wheel 11 moving downward along the column axis by 60 mm, first, in the initial stage of the downward movement, the steering wheel 11 moves downward along the column axis. Relatively, the rotating cover 4 rotates around the rotating shaft one 3 and slides along the surface of the upper shroud flap 8 to the convex surface 901 on the upper shroud body 9 under the action of the coil spring 13. The rotating cover 4 does not expose the internal column structure, and there is a relatively uniform gap relationship between the rear part of the rotating cover 4 and the decorative plate 12; Then, in the middle stage of the downward movement, as the steering wheel 11 continues to move downward along the column axis, the upper shroud flap 8 contacts the guiding block 1. Under the action of the guiding surface 101 on the guiding block 1, the upper shroud flap 8 rotates upward together with the base two 6 around the rotating shaft two 5. At this time, the rotating cover 4 slides along the convex surface 901 on the upper shroud body 9. Although the upper shroud flap 8 begins to separate from the lower shroud assembly 10, the rotating cover 4 has covered the upper shroud flap 8, and the rotating cover 4 does not expose the internal column structure, realizing a larger downward movement space for the steering wheel 11 to avoid and further increasing the downward movement stroke; As Figure 11 , during the process of the steering wheel 11 moving downward along the column axis by 120 mm, that is, in the later stage of the downward movement, the rotating cover 4 rotates around the rotating shaft one 3 and slides along the convex surface 901 on the upper shroud body 9 to the surface of the steering wheel 11 under the action of the coil spring 13. At this time, the upper shroud flap 8 is affected by the guiding surface 101 on the guiding block 1 and further tilts upward, converting the axial space requirement into the up and down direction, and the upper shroud flap 8 maintains a surface contact state with the guiding surface 101 under the action of the torsion spring 15. During this process, the rotating cover 4 also does not expose the internal column structure.
[0036] When the steering wheel 11 moves axially along the column, after the upper cover flip 8 slowly disengages from the guiding surface 101, it also seamlessly engages with the convex surface 901 on the upper cover body 9 under the action of the torsion spring 15, and at the same time returns to the state where the upper cover assembly and the lower cover assembly 10 are in contact and fit on both sides. At this time, the rotating cover 4 also slides along the steering wheel 11, the convex surface 901 on the upper cover body 9 and the upper cover flip 8 in sequence under the action of the coil spring 13, and finally returns to the initial state.
[0037] Compared with the traditional sheath flap structure, this set of mechanisms can achieve an ultra-long column adjustment stroke. During the up and down sliding adjustment and the up and down rotation adjustment, it can ensure that there are no any loopholes around the column sheath from beginning to end, and no internal structure can be seen from the upper line of sight, so as to achieve a good aesthetic appearance.
[0038] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
