Moreover, the described specific features, structures, materials or characteristics can be combined in any one or more embodiments or examples in a suitable manner.

[0034] Referring to Figures 1 to 4 Some embodiments of the present application propose a steering column, comprising:

[0035] a column body 100;

[0036] an upper column 200, the upper column 200 is slidingly arranged in the column body 100 along a first direction, and a circumferential side wall of the upper column 200 is provided with a matching plane 201, the matching plane 201 is parallel to the first direction;

[0037] a support assembly 300, the support assembly 300 is connected to the column body 100, and the support assembly 300 comprises an abutting portion 303, the abutting portion 303 abuts against the matching plane 201.

[0038] It can be understood that the first direction is the axial direction of the column body 100 and the upper column 200. The matching plane 201 is parallel to the first direction, i.e. parallel to the axis of the upper column 200, so that when the upper column 200 is adjusted by moving along the axial direction relative to the column body 100, the support assembly 300 and the upper column 200 will not interfere with each other.

[0039] The steering column of the embodiment can form a radial force between the column body 100 and the upper column 200 by supporting the fitting plane 201 of the upper column 200 in the peripheral direction through the support assembly 300, thereby eliminating the radial gap between the upper column 200 and the column body 100. Moreover, the support assembly 300 abuts against the fitting plane 201 of the upper column 200, has a circumferential direction rotation limiting effect on the upper column 200, and can improve the smoothness of the extension and retraction adjustment of the upper column 200 in the first direction. The provision of the fitting plane 201 also facilitates the supporting of the abutting portion 303, and can improve the stability between the abutting portion 303 and the upper column 200.

[0040] In some embodiments of the present application, in order to ensure the force balance of the support assembly 300 on the upper column 200, the direction of the force of the abutting portion 303 on the upper column 200 should be arranged along the radial direction of the upper column 200. Therefore, the support assembly 300 can be arranged along the radial direction of the upper column 200, and on this basis, a plurality of support assemblies 300 can be arranged along the axial direction of the upper column 200. A plurality of support assemblies 300 can also be arranged on one side of the upper column 200 along the circumferential direction of the upper column 200, and the plurality of support assemblies 300 are arranged in an axial symmetrical form, so that the resultant force of the plurality of support assemblies 300 on the upper column 200 is along the radial direction of the upper column 200, which can effectively eliminate the radial gap of the upper column 200 and maintain the stability of the upper column 200.

[0041] Referring to Figure 3 In some embodiments of the present application, the abutting portion 303 is provided with a rolling structure near one end of the upper column 200, and the rolling structure abuts against the fitting plane 201. When the steering column is working, the upper column 200 will be adjusted in extension and retraction relative to the column body 100 in the first direction, and the support assembly 300 needs to maintain the supporting of the upper column 200, which can have the following arrangement forms: one is that the support assembly 300 is fixedly connected to the column body 100; the other is that the support assembly 300 is slidingly connected to the column body 100, and the abutting portion 303 moves synchronously when the upper column 200 is adjusted in extension and retraction, so as to keep the abutting portion 303 stationary relative to the upper column 200. When the latter structure is used, the structure complexity is higher, and there are certain challenges in the design of the size, fitting precision and other aspects of the steering column. However, the former structure is beneficial to simplify the structural design of the steering column. The rolling structure of the embodiment can effectively match the former structure, so that the abutting portion 303 and the upper column 200 are in rolling frictional contact, which is beneficial to improve the smoothness and stability of the upper column 200 in the extension and retraction adjustment process.

[0042] Referring to Figure 3In some embodiments of the present application, the abutting portion 303 is provided with a support plane which is parallel to and abuts the matching plane 201. In this embodiment, the abutting portion 303 abuts the matching plane 201 through the support plane, which can improve the stability of the abutment between the abutting portion 303 and the upper pipe column 200. During the extension and retraction adjustment of the upper pipe column 200 relative to the pipe column body 100, the abutting portion 303 can effectively act on the upper pipe column 200 through the form of plane abutment, which is conducive to ensuring that a radial force is applied to the upper pipe column 200 to eliminate the radial gap and improve the smoothness of the upper pipe column 200 during the extension and retraction adjustment. Therefore, the form of plane abutment is conducive to improving the stability of the gap elimination mechanism of the support assembly 300.

[0043] With reference to Figure 3 In some embodiments of the present application, the abutting portion 303 is provided with a plurality of rolling structures which are distributed along a direction parallel to the matching plane 201, so that the contact ends of the rolling structures are located on the same plane, thereby forming a support plane. Obviously, the support plane is parallel to the matching plane 201 of the upper pipe column 200, and each rolling structure can simultaneously abut the matching plane 201 of the upper pipe column 200. When the upper pipe column 200 is controlled to extend and retract relative to the pipe column body 100, on the one hand, the abutting portion 303 can support the movement of the upper pipe column 200 through the rotation of the rolling structures, and on the other hand, the plurality of rolling structures can ensure the radial force on the upper pipe column 200. Therefore, this embodiment can simultaneously consider the radial force of the abutting portion 303 on the upper pipe column 200 and the stability of the abutment of the abutting portion 303 during the extension and retraction adjustment of the upper pipe column 200.

[0044] As a further embodiment of the above-mentioned embodiment, the abutting portion 303 is provided as a plane bearing. Since the plane bearing is provided with a plurality of rolling balls which are distributed on the same plane, the rolling balls are the rolling structures of the above-mentioned embodiment, and the contact surfaces of the rolling balls are the support plane of the above-mentioned embodiment. The specific design of the plane bearing can be adjusted as needed, such as a plurality of rolling balls which are distributed in a matrix along the horizontal and vertical directions, forming a rectangular profile structure, or a plurality of rolling balls which are distributed along a circular path, forming a ring-shaped profile structure. Based on the mature structure and good stability of the plane bearing, this embodiment can effectively ensure the rolling support of the abutting portion 303 on the upper pipe column 200.

[0045] In addition, the rolling structure can also be provided as a roller, and the plurality of rolling structures are a plurality of rollers, and the rotation shaft of each roller is parallel to the matching plane 201 and perpendicular to the first direction.

[0046] With reference to Figures 1 to 3In some embodiments of the present application, the threaded hole 101 is arranged along a direction perpendicular to the matching plane 201, and the support assembly 300 further comprises an adjusting part 301 threadedly connected to the threaded hole 101, and the abutting part 303 is arranged at one end of the adjusting part 301 close to the upper column 200. In the present embodiment, the adjusting part 301 can be adjusted in movement along the hole direction of the threaded hole 101, so as to adjust the size of the force applied by the abutting part 303 to the upper column 200. When the gap of the upper column 200 increases with the increase of working time, the adjusting part 301 can be screwed in the direction of the upper column 200, so as to ensure the radial force of the abutting part 303 to the upper column 200. Alternatively, in the initial debugging stage, the adjusting part 301 is installed to the threaded hole 101 at a proper depth position, so as to maintain the radial force of the abutting part 303 to the upper column 200.

[0047] It should be noted that when a plurality of support assemblies 300 are arranged around the upper column 200, the threaded hole 101 corresponding to each support assembly 300 can be arranged along the radial direction of the upper column 200, and does not need to be perpendicular to the matching plane 201.

[0048] Referring to Figure 2 In some embodiments of the present application, the threaded hole 101 is arranged to be open at one end away from the upper column 200, and the adjusting part 301 is arranged to have an operation hole at one end away from the upper column 200. In the initial debugging stage and the maintenance stage in normal working, when it is needed to change the position of the adjusting part 301 in the threaded hole 101, the worker can use a tool to extend into the open end of the threaded hole 101, and control the adjusting part 301 to screw in or out by cooperating with the operation hole on the adjusting part 301, so as to improve the convenience of operation.

[0049] The operation hole can adopt an internal hexagonal hole, and the worker can cooperate with an internal hexagonal wrench to operate. The operation hole can also adopt a slot-shaped hole, and the worker can cooperate with a slot-shaped screwdriver to operate. The operation hole can also be designed into other structural forms by those skilled in the art, and the operation can be performed by using an appropriate tool, which will not be described one by one.

[0050] In some embodiments of the present application, the threaded hole 101 is arranged to be open at one end away from the upper column 200, and the adjusting part 301 is arranged to have a connecting head at one end away from the upper column 200. In the initial debugging stage and the maintenance stage in normal working, when it is needed to change the position of the adjusting part 301 in the threaded hole 101, the worker can use a tool to extend into the open end of the threaded hole 101, and control the adjusting part 301 to screw in or out by cooperating with the connecting head on the adjusting part 301, so as to improve the convenience of operation.

[0051] The connecting head can adopt a hexagonal prism structure, and the staff can cooperate and operate through an external hexagonal wrench. The connecting head can also adopt a quadrangular prism structure or other structures, and the staff can correspondingly use an appropriate tool to clamp the connecting head, and control the rotating in or out of the adjusting part 301.

[0052] In some embodiments of the present application, the support assembly 300 further comprises an elastic member 302 abutting against one end of the abutting part 303 away from the upper pipe column 200, and the abutting part 303 is abuttingly matched with the plane 201 under the top-holding of the elastic member 302.

[0053] As the upper pipe column 200 wears with the increase of working time, the radial force of the abutting part 303 on the upper pipe column 200 will be weakened or even lost when the wear is aggravated, and the way of rotating the adjusting part 301 into the upper pipe column 200 to eliminate the radial gap after the radial gap of the upper pipe column 200 reappears belongs to lag adjustment. In the embodiment, the elastic member 302 is provided, which can be compressed by the adjusting part 301 at the initial installation and debugging stage, so as to apply an elastic pre-tightening force to the abutting part 303. When the wear is aggravated, the abutting part 303 can still maintain the state of abuttingly matching the plane 201 under the action of the elastic member 302, effectively eliminating the radial gap of the upper pipe column 200. Therefore, the provision of the elastic member 302 can adapt to the wear of the upper pipe column 200 in real time, ensure the radial force of the abutting part 303 on the upper pipe column 200, and improve the stability of the work of the support assembly 300.

[0054] Specifically, in some embodiments of the present application, the elastic member 302 is provided as a spring, and the number thereof can be one or more according to the support requirements.

[0055] Further, the spring can be provided as a spiral spring or a disc spring, or a combination of the two, and the number of the spiral spring or the disc spring can be flexibly set as needed. The elastic member 302 is provided as a spring, which is beneficial to simplify the structure design and can ensure the elastic support of the abutting part 303.

It can be understood that the driving mechanism 400 drives the upper pipe column 200 to extend or retract relative to the pipe column body 100 through the connecting bracket 202.

[0057] Specifically, referring to Figure 2 and Figure 4In some embodiments of the present application, the driving mechanism 400 comprises a driving motor unit 401 and a driving screw 402, the driving motor unit 401 is capable of controlling the driving screw 402 to move in the first direction. The driving screw 402 is hingedly connected to the support 202 at one end, thus capable of moving the upper column 200 by its own movement. It can be understood that the driving motor unit 401 only needs to engage the driving screw 402 by a gear structure, and the movement adjustment of the driving screw 402 can be realized by controlling the rotation of the gear structure.

[0058] In addition, the driving motor unit 401 and the driving screw 402 can also adopt other matching forms, such as: the driving screw 402 is connected to the power output end of the driving motor unit 401, and can be controlled by the driving motor unit 401 to rotate forward and reverse. The support 202 is provided with a nut seat which is threadedly connected to the driving screw 402. When the driving motor unit 401 controls the driving screw 402 to rotate forward or reverse, the nut seat will drive the support 202 to move in the first direction, driving the upper column 200 to extend or retract.
