[0033] The embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present application, and cannot be understood as limiting the present application.

[0034] Reference below Figure 1-Figure 5 The adjusting device 10 for a steering column assembly according to an embodiment of the present application is described. The adjusting device 10 includes an adjusting bracket 11, a cam assembly 12, a rotating shaft 13 and a limiting assembly 14. The adjusting bracket 11 is formed with a column mounting position for mounting a steering column 20. The cam assembly 12 is disposed on the adjusting bracket 11 and can selectively rotate relative to the adjusting bracket 11 to lock or unlock the adjusting bracket 11 and the steering column 20. The rotating shaft 13 is penetrated by the adjusting bracket 11. The rotating shaft 13 One end of the shaft 13 is linked with the cam assembly 12, and the limit assembly 14 is arranged at the other end of the shaft 13. The limit assembly 14 has a support member 141, a rolling member 142 and a limit member 143. The support member 141 is sleeved on the outer periphery of the shaft 13 and fits with the adjustment bracket 11. The limit member 143 is located at the other end of the shaft 13 and is linked with the shaft 13. The rolling member 142 is located between the support member 141 and the limit member 143 and is rotatably connected to the support member 141 and the limit member 143 respectively.

[0035] At present, the mechanical four-way adjustable steering column has a handle adjustment structure, which can realize the axial and angular adjustment of the column and ensure that after the column position is adjusted, it can reliably maintain the adjusted position to provide the driver with a comfortable steering wheel angle. The end of the existing handle adjustment structure uses an extended non-standard nut to be tightened through deformation, and uses an outsourced metal covering sheet to provide the required relative sliding. However, the metal covering sheet is easily deformed after long-term use and cannot effectively provide sliding friction.

[0036] like Figure 1As shown, specifically, the adjusting device 10 includes an adjusting bracket 11, a cam assembly 12, a rotating shaft 13 and a limiting assembly 14. The adjusting bracket 11 can be fixed to the vehicle body, and a column mounting position for mounting a steering column 20 is formed on the adjusting bracket 11. The cam assembly 12 can be set on the adjusting bracket 11, and the cam assembly 12 can selectively rotate relative to the adjusting bracket 11 to achieve locking or unlocking the adjusting bracket 11 and the steering column 20. It should be noted that the cam assembly 12 can generate axial movement when rotating. When the cam assembly 12 moves, the cam assembly 12 can move toward or away from the adjusting bracket 11. When the cam assembly 12 moves toward the adjusting bracket 11, the adjusting bracket 11 and the steering column 20 can be locked. The cam assembly When 12 moves away from the adjusting bracket 11, the adjusting bracket 11 and the steering column 20 can be unlocked. The movement of the cam assembly 12 toward or away from the adjusting bracket 11 can be determined by the rotation direction of the cam assembly 12. A handle 15 is also provided on the cam assembly 12. The user can control the rotation direction of the cam assembly 12 by controlling the handle 15, and then control the locking or unlocking of the adjusting bracket 11 and the steering column 20. When the adjusting bracket 11 and the steering column 20 are unlocked, the user can adjust the angle and axial position of the steering column 20 to make it in a suitable position to ensure the user's driving feel. After the user has adjusted the position of the steering column 20, the adjusting bracket 11 and the steering column 20 are locked to fix the steering column 20 and maintain the current position.

[0037] like Figure 2 As shown, the rotating shaft 13 can be passed through the adjusting bracket 11, one end of the rotating shaft 13 can be linked with the cam assembly 12, and the other end of the rotating shaft 13 can be connected with the limiting assembly 14. The rotating shaft 13 can ensure that the cam assembly 12 can rotate along the axial direction of the rotating shaft 13 to achieve radial limitation of the cam assembly 12. The limiting assembly 14 may include a supporting member 141, a rolling member 142 and a limiting member 143. The supporting member 141 can be sleeved on a part of the outer periphery of the rotating shaft 13, and the supporting member 141 can fit with the adjusting bracket 11. In actual use, the thickness of the supporting member 141 can be adjusted within a certain allowable range to achieve different widths of the adjusting bracket 11, so that the limiting assembly 14 is more expandable.

[0038] The limit member 143 can be set at the other end of the rotating shaft 13, and the limit member 143 can be linked with the rotating shaft 13. The rolling member 142 can be located between the support member 141 and the limit member 143, and the rolling member 142 can be rotatably connected to the support member 141 and the limit member 143 respectively. The rolling member 142 can convert the relative rotation between the support member 141 and the limit member 143 into rolling friction, ensuring that the support member 141 can remain stationary when the limit member 143 rotates. Compared with the prior art, the use of the rolling member 142 can further improve the service life of the limit assembly 14, and it is easier to lock or unlock the adjustment bracket 11 and the steering column 20 when adjusting the column, thereby improving the adjustment feel and reliability.

[0039] In short, the adjustment device 10 of the embodiment of the present application has an adjustment bracket 11 and a limit assembly 14. The adjustment bracket 11 can be provided with a cam assembly 12 and a rotating shaft 13, and the cam assembly 12 can be used to lock or unlock the adjustment bracket 11 and the steering column 20. The cam assembly 12 will drive the rotating shaft 13 to rotate synchronously during the adjustment process. The limit assembly 14 has a support member 141, a rolling member 142 and a limit member 143. The limit member 143 can be linked with the rotating shaft 13. The rolling member 142 is located between the support member 141 and the limit member 143 and is rollingly connected with the support member 141 and the limit member 143. The use of this structure can make it easier to lock or unlock the adjustment bracket 11 and the steering column 20 when adjusting the steering column 20, thereby ensuring the user's adjustment feel and improving the service life and reliability of the adjustment device 10.

[0040] like Figure 3 and Figure 4 As shown, in some embodiments of the present application, the rolling member 142 may include a rolling bracket 1421 and a rolling body 1422. The rolling bracket 1421 may be arranged between the support frame and the stopper 143, and the rolling bracket 1421 may be constructed as a ring or arc arranged concentrically with the rotating shaft 13. The rolling body 1422 may be rotatably arranged on the rolling bracket 1421, and the rolling body 1422 may contact the support member 141 and the stopper 143 respectively, so as to realize rolling friction between the rolling member 142 and the support member 141 and the stopper 143. Compared with the prior art, the rolling friction may reduce the wear of the rolling support member 141, reduce the deformation of the support member 141, and increase the service life of the support member 141. In a specific embodiment, the rolling body 1422 may be constructed as a sphere. By constructing the rolling member 142 as a sphere, support and protection may be provided for the rolling member 142, the unidirectional stress of the support member 141 and the stopper 143 may be reduced, and a better rolling friction effect may be provided.

[0041] like Figure 3 and Figure 4As shown, in some embodiments of the present application, the support member 141 and the limiting member 143 are respectively formed with a first limiting wall 1411 and a second limiting wall 1433 on both sides facing each other, the rolling member 142 can be arranged between the first limiting wall 1411 and the second limiting wall 1433, and a guide portion 144 can be formed on at least one of the first limiting wall 1411 and the second limiting wall 1433, and the guide portion 144 can cooperate with the rolling body 1422, and the rolling body 1422 can rotate along the guide portion 144, wherein the guide portion 144 can be arranged in a surrounding manner along the axial direction of the rotating shaft 13, so that the rolling body 1422 can move in a surrounding manner along the axial direction of the rotating shaft 13. It can be understood that the guide portion 144 can guide and limit the rolling body 1422 to ensure that the rolling body 1422 can move in a surrounding manner in the circumferential direction.

[0042] like Figure 3 and Figure 4 As shown, in some embodiments of the present application, the guide portion 144 can be constructed as a guide groove formed on the first limiting wall 1411 and the second limiting wall 1433 respectively, and the guide groove is recessed in the direction away from each other of the first limiting wall 1411 and the second limiting wall 1433. A part of the rolling body 1422 can be accommodated in the guide groove on the first limiting wall 1411, and another part of the rolling body 1422 can be accommodated in the guide groove on the second limiting wall 1433. By providing the guide groove on the first limiting wall 1411 and the second limiting wall 1433, the matching effect between the rolling body 1422 and the first limiting wall 1411 and the second limiting wall 1433 can be improved. In addition, the guide groove can also allow the rolling element 142 to bear radial loads and axial loads at the same time, providing more convenient conditions for the range and speed of subsequent force adjustment of the handle 15.

[0043] like Figure 4 As shown, in some embodiments of the present application, the limit member 143 includes a limit member body 1431 and an extension portion 1432. The limit member body 1431 can be limitedly matched with the end of the rotating shaft 13. The extension portion 1432 can be arranged at one end of the limit member body facing the support member 141, and the extension portion 1432 can extend radially. A second limit wall 1433 is formed on the surface of the end face of the extension portion 1432 facing the support surface. The extension portion 1432 can increase the radial cross-sectional area of ​​the limit member 143 to ensure that the rolling body 1422 can fit the extension portion 1432, and a guide groove can be formed on the extension portion 1432. The other part of the rolling body 1422 can be accommodated in the guide groove and move circumferentially along the rotating shaft 13.

[0044] In some embodiments of the present application, the diameter of the extension portion 1432 and the diameter of the support member 141 are both larger than the diameter of the rolling bracket 1421. Since the rolling body 1422 is arranged between the rolling members, the diameters of the extension portion 1432, the diameters of the support member 141 and the diameters of the rolling bracket 1421 are set to the above-mentioned relationship to ensure that the rolling body 1422 can fit and roll with the extension portion 1432 and the support member 141 more effectively, thereby ensuring the stability of the extension portion 1432 during the rotation process, and at the same time ensuring that the contact point between the rolling body 1422 and the extension portion 1432 and the support member 141 can be located on the surfaces of the extension portion 1432 and the support member 141 facing each other.

[0045] like Figure 1 As shown, in some embodiments of the present application, the adjusting device 10 also includes a clamping plate 16, which can be arranged between the adjusting bracket 11 and the support member 141, and the clamping plate 16 can be respectively abutted against the adjusting bracket 11 and the support member 141, and a through hole for the rotating shaft 13 to pass through is formed on the clamping plate 16, thereby realizing radial limitation of the rotating shaft 13, and the clamping plate 16 can also provide a support point for the support plate, so that the support plate is more easily subjected to force.

[0046] like Figure 5 As shown, the steering column assembly of the embodiment of the present application is briefly described below.

[0047] According to the embodiment of the present application, the steering column assembly is provided with a steering column 20 and the adjusting device 10 of the above embodiment.
