DETAILED DESCRIPTION

[0043] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the embodiments described are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

[0044] Embodiments of the present application provide a steering column adjustment mechanism, a steering column barrel assembly, a steering system, and a vehicle.

[0045] Figure 1 A schematic structural diagram of an embodiment of a steering column adjustment mechanism provided in an embodiment of the present application. Figure 3 3 is a structural diagram of an embodiment of a steering column assembly provided by an embodiment of the present application, wherein the intermediate column and the intermediate shaft swing to a first limit angle. Figure 4 : is a structural diagram of an embodiment of the steering column assembly provided by the present application, wherein the intermediate column and the intermediate shaft swing to the second limit angle. Figure 1 、 Figure 3 and Figure 4As shown, the steering column adjustment mechanism 10 includes a support structure 11, an intermediate column 12, a connecting rod structure 14, and a drive structure 13. The intermediate column 12 is rotatably connected to the support structure 11. The drive structure 13 is used to drive the intermediate column 12 to swing relative to the support structure 11, thereby driving the intermediate shaft 20 to swing, thereby adjusting the angle of the steering wheel connected to the intermediate shaft 20.

[0046] Among them, the first end of the connecting rod structure 14 is connected to the supporting structure 11, the second end of the connecting rod structure 14 is connected to the intermediate column 12, the driving structure 13 is arranged on the intermediate column 12, and the driving structure 13 is used to drive the connecting rod structure 14 to move, so that the connecting rod structure 14 drives the intermediate column 12 to swing relative to the supporting structure 11.

[0047] The intermediate column 12 of the steering column adjustment mechanism 10 provided in the embodiment of the present application is connected to the support structure 11 via a connecting rod structure 14. The connecting rod structure 14 is driven by a driving structure 13 to move, thereby causing the intermediate column 12 to swing relative to the support structure 11, thereby adjusting the angle between the intermediate column 12 and the intermediate column 12. Due to the stable movement and simple structure of the connecting rod structure 14, while achieving stable swinging of the intermediate column 12, the transmission structure between the driving structure 13 and the intermediate column 12 can also be simplified, which helps reduce the cost of the steering column adjustment mechanism 10.

[0048] The intermediate cylinder 12 is used to be connected to the intermediate shaft 20. When the intermediate cylinder 12 swings, it drives the intermediate shaft 20 to swing together.

[0049] In some embodiments, the connecting rod structure 14 includes a first connecting rod 141 hinged to the intermediate column 12, and a second connecting rod 142 hinged to the support structure 11. The driving structure 13 is used to drive the first connecting rod 141 and the second connecting rod 142 to rotate, so as to drive the intermediate column 12 to swing relative to the support structure 11.

[0050] It will be appreciated that, because the first connecting rod 141 is hingedly connected to the intermediate cylinder 12, the second connecting rod 142 is hingedly connected to the support structure 11, and the intermediate cylinder 12 is rotationally connected to the support structure 11, when the driving structure 13 drives the first connecting rod 141 and the second connecting rod 142 to rotate, the relative positions of the hinged portions of the intermediate cylinder 12 and the first connecting rod 141, and the hinged portions of the support structure 11 and the second connecting rod 142, will change, thereby causing the intermediate cylinder 12 to rotate relative to the support structure 11. Therefore, by having the driving structure 13 drive the first connecting rod 141 and the second connecting rod 142 to rotate, the intermediate cylinder 12 can be caused to swing relative to the support structure 11, resulting in a relatively simple structure.

[0051] It should be noted that the end of the second connecting rod 142 hinged to the support structure 11 is the first end of the connecting rod structure 14 . The end of the first connecting rod 141 hinged to the middle column 12 is the second end of the connecting rod structure 14 .

[0052] like Figure 1 and Figure 2 As shown, the first connecting rod 141 can be connected to the second connecting rod 142 via the third connecting rod 144, and the driving structure 13 is used to drive the third connecting rod 144 to rotate the first connecting rod 141 and the second connecting rod 142. As a result, the connection between the driving structure 13 and the connecting rod structure 14 is more convenient, and by driving the third connecting rod 144 to move, the rotation angle of the first connecting rod 141 and the second connecting rod 142 can be accurately controlled, thereby achieving precise adjustment of the swing of the intermediate cylinder 12 relative to the support structure 11.

[0053] In some embodiments, one end of the first connecting rod 141 can be hinged to the intermediate cylinder 12, the other end of the first connecting rod 141 can be hinged to one end of the third connecting rod 144, one end of the second connecting rod 142 can be hinged to the support structure 11, and the other end of the second connecting rod 142 can be hinged to the other end of the third connecting rod 144. The driving structure 13 is connected to the third connecting rod 144. When the driving structure 13 drives the third connecting rod 144 to move, it can drive the first connecting rod 141 and the second connecting rod 142 to rotate relative to the third connecting rod 144.

[0054] In some embodiments, the intermediate cylinder 12 includes a first connection portion 121 for rotationally connecting to the support structure 11, and a first hinge portion 122 hingedly connected to the first connecting rod 141. The support structure 11 includes a second hinge portion 111 for hingedly connecting to the second connecting rod 142. The first hinge portion 122 is located between the second hinge portion 111 and the first connection portion 121. Therefore, when the driving structure 13 drives the third connecting rod 144 to move, it can more stably drive the intermediate cylinder 12 to swing relative to the support structure 11.

[0055] Specifically, the intermediate cylinder 12 includes a cylinder portion 124, which is used to allow the intermediate shaft 20 to pass through, thereby connecting the intermediate cylinder 12 to the intermediate shaft 20. This can further stabilize the connection between the intermediate shaft 20 and the intermediate cylinder 12. The second hinge portion 111, the first hinge portion 122, and the first connecting portion 121 are sequentially arranged along the length of the cylinder portion 124. The distance from the first hinge portion 122 to the second hinge portion 111 is shorter than the distance from the first hinge portion 122 to the first connecting portion 121.

[0056] The intermediate cylinder 12 includes a second connecting portion 123 for connecting to the driving structure 13. The driving structure 13 is connected to the third connecting rod 144. The driving structure 13 is used to drive the third connecting rod 144 toward or away from the second connecting portion 123, thereby driving the first connecting rod 141 and the second connecting rod 142 to rotate relative to the third connecting rod 144.

[0057] In other embodiments, Figures 5 to 8 As shown, the first connecting rod 141 and the second connecting rod 142 may also be hinged via a hinge shaft 143. Thus, the connecting rod structure 14 can be simplified to further reduce the cost of the steering column adjustment mechanism 10.

[0058] The hinge shaft 143 can be connected to the driving structure 13, and the driving structure 13 drives the hinge shaft 143 to move, thereby driving the first connecting rod 141 and the second connecting rod 142 to rotate. In this way, the driving structure 13 can push or pull the first connecting rod 141 and the second connecting rod 142 to rotate by driving the hinge shaft 143 to move, making the connection between the driving structure 13 and the connecting rod structure 14 simpler.

[0059] Specifically, one end of the first link 141 can be hinged to the middle column 12, the other end of the first link 141 can be rotatably connected to the hinge shaft 143, one end of the second link 142 can be hinged to the support structure 11, and the other end of the second link 142 can be rotated with the hinge shaft 143, so that the first link 141 and the second link 142 are hinged through the hinge shaft 143.

[0060] The drive structure 13 is connected to the hinge shaft 143. When the drive structure 13 drives the hinge shaft 143 to move, it drives the first connecting rod 141 and the second connecting rod 142 to rotate relative to each other. The intermediate cylinder 12 includes a second connecting portion 123 for connecting to the drive structure 13. The drive structure 13 is used to drive the hinge shaft 143 toward or away from the second connecting portion 123, thereby driving the first connecting rod 141 and the second connecting rod 142 to rotate relative to each other.

[0061] In some embodiments, the intermediate cylinder 12 includes a first connection portion 121 for rotationally connecting to the support structure 11, and a first hinge portion 122 hingedly connected to the first connecting rod 141. The support structure 11 includes a second hinge portion 111 for hingedly connecting to the second connecting rod 142. The first hinge portion 122 and the second hinge portion 111 are both located on the side of the hinge shaft 143 away from the first connection portion 121. Therefore, when the driving structure 13 drives the hinge shaft 143 to move, it can more stably drive the intermediate cylinder 12 to swing relative to the support structure 11.

[0062] Specifically, the second hinge portion 111, the hinge axis 143, and the first connection portion 121 are sequentially distributed along the length of the cylindrical portion 124. The distance from the second hinge portion 111 to the hinge axis 143 is smaller than the distance from the hinge axis 143 to the first connection portion 121. The first hinge portion 122 and the second hinge portion 111 are located on the same side of the hinge axis 143 along the length of the cylindrical portion 124.

[0063] In other embodiments, the driving structure 13 may be directly connected to the first connecting rod 141 or the second connecting rod 142 , and drive the first connecting rod 141 or the second connecting rod 142 to rotate, thereby driving the intermediate cylinder 12 to swing relative to the supporting structure 11 .

[0064] In some embodiments, the driving structure 13 may include a connecting member 131 and a driving member 132. The connecting member 131 is in driving connection with the driving member 132. The connecting member 131 is connected to the connecting rod structure 14. The driving member 132 is connected to the intermediate cylinder 12. The driving member 132 is used to drive the connecting member 131 to move, thereby driving the connecting rod structure 14 to move. Since the connecting member 131 is connected to the connecting rod structure 14, when the driving member 132 drives the connecting member 131 to move, it can drive the connecting rod structure 14 to move together.

[0065] The intermediate cylinder 12 may include a second connection portion 123 for connecting to a driving member 132, and the driving member 132 may be used to drive the connecting member 131 toward or away from the second connection portion 123. In this way, the movement process of the driving member 132 is simpler, which is conducive to simplifying the structure of the driving member 132 and further reducing the cost of the driving structure 13.

[0066] In some embodiments, as Figure 1 、 Figure 6 As shown, the driving member 132 may include a screw rod 1321 and a motor 1322. The screw rod 1321 is connected to the connecting member 131, and the motor 1322 is used to drive the screw rod 1321 to rotate so that the connecting member 131 moves along the length of the screw rod 1321. By controlling the rotation angle of the screw rod 1321, the motor 1322 can accurately drive the connecting member 131 to move a certain distance along the length of the screw rod 1321, thereby accurately controlling the swing angle of the intermediate cylinder 12 relative to the support structure 11.

[0067] The screw rod 1321 can be located on the side of the motor 1322 facing the support structure 11 so that the screw rod 1321 is close to the support structure 11 , making it easier for the screw rod 1321 to drive the connecting rod structure 14 to move through the connecting member 131 .

[0068] In some embodiments, the screw rod 1321 can be located on the side of the motor 1322 facing the intermediate cylinder 12. In this way, the space between the motor 1322 and the intermediate cylinder 12 can be fully utilized, making the structure of the steering column adjustment mechanism 10 more compact and helping to reduce the overall volume of the steering column adjustment mechanism 10.

[0069] In some embodiments, the rotation axis of the motor 1322 can be substantially parallel to the screw rod 1321. This is beneficial to the overall size of the motor 1322 and the screw rod 1321 on the rotation axis X of the intermediate column 12 relative to the support structure 11, thereby reducing the overall volume of the steering column adjustment mechanism 10.

[0070] In some embodiments, as Figure 1 As shown, the intermediate column 12 can rotate relative to the support structure 11 around the rotation axis X, so that at least a portion of the drive structure 13 can be located on one side of the intermediate column 12 along the extension direction of the rotation axis X. As a result, the overall size of the steering column adjustment mechanism 10 in the swing direction of the intermediate column 12 can be reduced.

[0071] In some embodiments, the connecting rod structure 14 and the driving structure 13 may be located on the same side of the intermediate cylinder 12 to facilitate connection between the driving mechanism and the connecting rod structure 14 .

[0072] In some embodiments, the maximum swing angle of the center column 12 can be greater than or equal to 6° to expand the angle adjustment range of the steering wheel. The maximum swing angle of the center column 12 can be 6.1°, 6.3°, 6.4°, 7°, etc., depending on actual needs.

[0073] Among them, Figure 3 As shown, the driving structure 13 can drive the intermediate cylinder 12 and the intermediate shaft 20 to swing to a first limit angle relative to the supporting structure 11. Figure 4 As shown, the driving structure 13 can also drive the intermediate cylinder 12 and the intermediate shaft 20 to swing in the opposite direction relative to the support structure 11 to a second limit angle. When the intermediate cylinder 12 and the intermediate shaft 20 swing from the first limit angle to the second limit angle relative to the support structure 11, the angle at which the intermediate cylinder 12 rotates is the maximum swing angle of the intermediate cylinder 12.

[0074] like Figure 9 and Figure 10 As shown, when the intermediate cylinder 12 and the intermediate shaft 20 swing from the first limit angle to the second limit angle relative to the support structure 11, the angle of rotation of the intermediate cylinder 12 and the intermediate shaft 20 relative to the support structure 11 is substantially proportional to the first limit angle. Figure 9As shown, when the connecting rod structure 14 of the steering column adjustment mechanism 10 includes the first connecting rod 141, the second connecting rod 142 and the third connecting rod 144, the corresponding angle when the intermediate cylinder 12 and the intermediate shaft 20 are at the first limit angle is -3.2°, and when the intermediate cylinder 12 and the intermediate shaft 20 are at the second limit angle, the corresponding angle is +3.2°. Figure 10 As shown, when the connecting rod structure 14 of the steering column adjustment mechanism 10 includes the first connecting rod 141, the second connecting rod 142 and the third connecting rod 144, the corresponding angle when the intermediate column 12 and the intermediate shaft 20 are at the first extreme angle is -3.2°, and the corresponding angle when the intermediate column 12 and the intermediate shaft 20 are at the second extreme angle is +3.1°.

[0075] from Figure 9 and 10 It can be seen from the experimental data that the steering column adjustment mechanism 10 provided in the embodiment of the present application can achieve precise adjustment of the swing angle of the intermediate column tube 12.
