Detailed description of the specific implementation

[0056] The embodiments of the present application will be described in detail below. Examples of the embodiments are shown in the accompanying drawings, where the same or similar reference numerals represent the same or similar elements or elements with the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to explain the present application, and should not be construed as limiting the present application.

[0057] In the description of the present application, the terms "first" and "second" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the present application, the meaning of "a plurality" is at least two, such as two, three, etc., unless otherwise specifically defined.

[0058] The following will Figures 1 - 16 describe in detail the steering column assembly 10 according to an embodiment of the present application, the steering system 20 having the steering column assembly 10, and the vehicle 100 having the steering column assembly 10 or the steering system 20.

[0059] Referring to Figures 1 - 3 As shown, the steering column assembly 10 according to an embodiment of the present application may include a steering column 1 and an adjustment mechanism. The steering column 1 is used to connect the steering wheel, and the adjustment mechanism is connected to the steering column 1. The adjustment mechanism is used to drive the steering column 1 to move in a first direction to adjust the position of the steering column 1 in the first direction.

[0060] Specifically, the adjustment mechanism can drive the entire steering column 1 to move in the first direction, rather than a part of the structure of the steering column 1 moving. In this way, the moving range of the steering column 1 is wide, and the position adjustment range is relatively large.

[0061] The steering column 1 is used to connect the steering wheel, and the first direction is Figures 1 - 2 the F1 - F2 direction in

[0062] In some embodiments, the first direction is the axial direction of the steering column 1 and also the height direction of the steering column 1. When the steering column 1 moves in the first direction, the axial position adjustment of the steering column 1 is achieved, that is, the height adjustment of the steering column 1 is achieved. The adjustment mechanism drives the entire steering column 1 to move, making the overall moving distance of the steering column 1 longer.

[0063] In the related art, the steering column includes an inner sleeve and an outer sleeve. The adjusting mechanism drives the inner sleeve to telescopically move relative to the outer sleeve. The moving distance of the inner sleeve is limited, and the relatively long structure of the inner sleeve will further shorten the stroke of the inner sleeve. According to the steering column assembly 10 of the embodiment of the present application, the adjusting mechanism directly drives the steering column 1 to move in the first direction to achieve the position adjustment of the steering column 1 in the first direction, and the position adjustment range of the steering column is relatively large.

[0064] In some embodiments of the present application, referring to Figures 1 - 4 、 Figure 7 as shown, the adjusting mechanism includes a driving device 5 and a connecting component. The driving device 5 is connected to the steering column 1 through the connecting component. The driving device 5 is used to drive the connecting component to move. When the connecting component moves, it drives the steering column 1 to move in the first direction. The connecting component is connected to the steering column 1, and the driving force of the driving device 5 can be transmitted to the steering column 1 through the connecting component. The arrangement positions of the driving device 5 and the steering column 1 are more flexible.

[0065] In some embodiments of the present application, referring to Figures 1 - 4 、 Figure 7 as shown, the connecting component includes: a mounting seat 3 and a support member 2. The support member 2 is connected to the steering column 1. The support member 2 is mounted on the mounting seat 3. When the support member 2 is driven, it is adapted to move relative to the mounting seat 3 in the first direction. In some embodiments, when the support member 2 is driven by the driving device 5, it is adapted to move relative to the mounting seat 3 in the first direction. When the support member 2 moves in the first direction, it drives the steering column 1 to move in the first direction. That is to say, by driving the support member 2 to move relative to the mounting seat 3 in the first direction, the position adjustment of the steering column 1 in the first direction can be realized. When the support member 2 moves, it drives the entire steering column 1 to move, so that the overall moving distance of the steering column 1 is longer. The driving device 5 is used to drive the support member 2 to move relative to the mounting seat 3 in the first direction.

[0066] In some alternative embodiments, the driving force source for driving the support member 2 to move can also be provided manually by the user.

[0067] There is no limitation on the shapes of the support member 2 and the mounting seat 3. For example, the support member 2 can be configured as a block structure, a plate structure, etc., and the mounting seat 3 can be configured as a block structure, a plate structure, etc. In some embodiments of the present application, referring to Figures 5 - 6 and Figures 10 - 11 as shown, the support member 2 is configured as a support plate, and the mounting seat 3 is configured as a mounting plate. In this way, the thicknesses of both the support member 2 and the mounting seat 3 are relatively thin, which is beneficial to saving materials.

[0068] In some embodiments, referring to Figure 6 and Figure 13As shown, the support member 2 includes mounting arms 23, and the steering column 1 has a housing 11. The mounting arms 23 are connected to the housing 11. There may be two oppositely arranged mounting arms 23, and there is a mounting space between the two mounting arms 23. The housing 11 is at least partially clamped between the two mounting arms 23.

[0069] The steering column assembly 10 of the present application has the functions of height adjustment and storage of the steering column 1. During the realization of the height adjustment and storage functions, Figures 4 - 6 An actuator for the storage adjustment of the steering column 1 is shown. The mechanism for realizing this function mainly includes a driving device 5, a support member 2, and a mounting seat 3. The driving device 5 automates the process of adjusting the axial position of the steering column 1. The driving device 5 can be electrically connected to the control device of the vehicle 100. Whether the driving device 5 operates can be controlled by a control signal sent by the control device.

[0070] The steering column assembly 10 of the present application can realize the storage function of the steering column 1 in the limited layout space in the vehicle by directly increasing the axial adjustment stroke on the basis of meeting the axial height adjustment function of the steering column 1 through a single movable support member 2 and a single mounting seat 3, with a small number of structural parts and a compact structure.

[0071] According to the steering column assembly 10 of the embodiment of the present application, when the support member 2 is driven, it is adapted to move relative to the mounting seat 3 in the first direction to drive the steering column 1 to move in the first direction, thereby realizing the position adjustment of the steering column 1 in the first direction. The adjustment process is simple and the structure is simple. The support member 2 directly drives the steering column 1 to move, realizing the single-stage adjustment of the axial position of the steering column 1. Compared with the multi-stage adjustment in the related art, the adjustment process is greatly simplified.

[0072] In some embodiments of the present application, the support member 2 is in sliding fit with the mounting seat 3. The cooperation method is simple, making the position adjustment process of the steering column 1 simple.

[0073] In some embodiments of the present application, referring to Figures 1 - 4 、 Figure 7 As shown, the driving device 5 includes a driving member 51 and a transmission member 52. The transmission member 52 is in transmission connection with the driving member 51, and the transmission member 52 is connected to the support member 2. The power of the driving member 51 is transmitted to the support member 2 through the transmission member 52. In this way, the driving member 51 can be arranged at a position far from the support member 2, and the support member 2 is not easily knocked against the driving member 51 during movement, with a more reasonable layout. And by setting the transmission member 52, it is beneficial to increase the moving stroke of the support member 2, thereby increasing the adjustment stroke of the steering column 1.

[0074] In some embodiments of the present application, the driving member 51 can be a motor or a combination of a motor and a reducer.

[0075] In some embodiments, the driving member 51 can be installed on the mounting seat 3.

[0076] In a specific embodiment, the driving member 51 can be fixedly connected to the mounting seat 3 through a first fastener.

[0077] It should be noted that in this application, various fasteners (including the first fastener and the second fastener, the third fastener, etc. mentioned later) can be bolts and nuts, screws, rivets, etc. When the fastener is a threaded fastener, the two parts to be connected are convenient to disassemble and assemble, which is convenient for replacing and repairing vulnerable parts.

[0078] In some embodiments of this application, with reference to Figure 4 , Figure 7 As shown, the transmission member 52 includes a lead screw 521 and a nut slider 522. The lead screw 521 is in transmission connection with the driving member 51, and the nut slider 522 is connected to the support member 2. The driving member 51 drives the nut slider 522 to move along the length direction of the lead screw 521, so as to drive the support member 2 to move along the length direction of the lead screw 521. In other words, when the nut slider 522 moves along the length direction of the lead screw 521, it can drive the support member 2 to move along the length direction of the lead screw 521. Specifically, the nut slider 522 is in threaded connection with the lead screw 521, so that when the lead screw 521 rotates, the support member 2 moves along the length direction of the lead screw 521 along with the nut slider 522. When the length of the lead screw 521 is relatively long, the support member 2 can have a relatively large moving stroke, so that the steering column 1 has a relatively large adjustment stroke, which is beneficial to realizing the storage function of the steering column 1.

[0079] Among them, the nut slider 522 and the support member 2 can be directly connected or indirectly connected. In the Figure 4 example, the nut slider 522 and the support member 2 are indirectly connected through the collapse structure 4.

[0080] In some embodiments of this application, one end of the lead screw 521 far from the driving member 51 is supported by a bearing. With reference to Figures 4 - 5 As shown, a bearing seat 32 is provided on the mounting seat 3, and a bearing is provided in the bearing seat 32. One end of the lead screw 521 far from the driving member 51 is supported by the bearing. In this way, when the lead screw 521 rotates, the lead screw 521 is not easily bent. Since the adjustment stroke for storing the steering column 1 is relatively long, resulting in a relatively long length of the lead screw 521, problems such as poor stiffness of the lead screw 521, large running noise, and poor smoothness are likely to occur. In this application, by adding a bearing seat 32 on the mounting seat 3, the bearing can support the outer extension end of the lead screw 521, improving the problem of poor stiffness existing in the cantilever support and enhancing the stiffness and reliability of the axial adjustment of the steering column 1.

[0081] In some embodiments of this application, with reference toFigures 4 - 6 As shown, one of the support member 2 and the mounting base 3 has a guiding groove 31, and the other has a guiding rail 21. The guiding rail 21 cooperates with the guiding groove 31, and the guiding rail 21 extends along a first direction. The guiding groove 31 also extends along the first direction. The cooperation between the guiding rail 21 and the guiding groove 31 can guide the movement of the support member 2, so that the support member 2 moves strictly in the first direction.

[0082] In some embodiments, such as Figures 4 - 6 、 Figure 9 shown, the support member 2 has a guiding rail 21, and the mounting base 3 has a guiding groove 31. The guiding rail 21 of the support member 2 can slide along the first direction within the guiding groove 31 of the mounting base 3.

[0083] In some embodiments not shown in the figure, the support member 2 has a guiding groove 31, and the mounting base 3 has a guiding rail 21. The guiding groove 31 of the support member 2 can slide along the guiding rail 21 of the mounting base 3.

[0084] In some embodiments of the present application, referring to Figures 4 - 5 shown, a limiting structure 33 is provided at one end of the mounting base 3 away from the steering wheel. The limiting structure 33 is used to limit the travel of the support member 2. Specifically, the limiting structure 33 is used to limit the extreme position of the support member 2 moving downward (i.e., moving in the F2 direction). The limiting structure 33 can play a role in end protection to prevent the support member 2 from detaching from the mounting base 3 from below.

[0085] In a specific embodiment, the limiting structure 33 can be configured as a limiting block, a limiting plate, a limiting ball, etc.

[0086] In Figures 4 - 5 the shown example, the support member 2 has a guiding rail 21, the mounting base 3 has a guiding groove 31, and a limiting structure 33 is provided at one end of the guiding groove 31 away from the steering wheel. The limiting structure 33 is used to limit the extreme position of the downward movement of the guiding rail 21. The limiting structure 33 can be provided at the end of the guiding groove 31 to play an end protection role in the travel of the support member 2.

[0087] In some embodiments not shown in the figure, the support member 2 has a guiding groove 31, the mounting base 3 has a guiding rail 21, and a limiting structure 33 is provided at one end of the guiding rail 21 away from the steering wheel. The limiting structure 33 is used to limit the extreme position of the downward movement of the support member 2.

[0088] In some embodiments of the present application, the guiding groove 31 is a dovetail groove, and the guiding rail 21 is a dovetail guiding rail. The guiding groove 31 and the guiding rail 21 are configured as a dovetail structure, which can effectively prevent the support member 2 from detaching from the mounting base 3 and has a good guiding effect.

[0089] In other embodiments of the present application, the guiding groove 31 is a rectangular groove, and the guiding rail 21 is a rectangular guiding rail.

[0090] During the process of adjusting the position of the steering column 1 in the first direction, a control signal is transmitted to the driving member 51. The driving member 51 starts to drive the lead screw 521 to rotate. The nut slider 522 on the lead screw 521 moves along the axis of the lead screw 521. At the same time, the nut slider 522 drives the support member 2 to move in the first direction. Under the action of different control signals, the height adjustment of the steering wheel with a small stroke can be realized, and the storage adjustment of the steering wheel with a long stroke can also be realized. The schematic diagram of the overall adjustment process is as Figures 1 - 2 shown. Among them, Figure 1 in the state shown, the steering wheel is closer to the driver; Figure 2 in the state shown, the steering wheel is farther from the driver. When the steering column 1 moves slightly in the F1 direction or the F2 direction, the height adjustment of the steering wheel with a small stroke can be realized; when the steering column 1 moves significantly in the F2 direction, the storage adjustment of the steering wheel with a long stroke can be realized.

[0091] In some embodiments of the present application, referring to Figures 8 - 11 shown, the steering column assembly 10 further includes a clearance adjusting and friction reducing structure 7. The clearance adjusting and friction reducing structure 7 is arranged between the support member 2 and the mounting seat 3. The clearance adjusting and friction reducing structure 7 is used to adjust the clearance between the support member 2 and the mounting seat 3. When the support member 2 slides on the mounting seat 3 in the first direction and the clearance between the support member 2 and the mounting seat 3 changes, the clearance adjusting and friction reducing structure 7 can adjust the clearance between the support member 2 and the mounting seat 3 to reduce the sway of the support member 2 relative to the mounting seat 3. For example, the clearance adjusting and friction reducing structure 7 can make the clearance between the support member 2 and the mounting seat 3 the largest, and the clearance adjusting and friction reducing structure 7 fills the clearance to prevent the sway of the support member 2 relative to the mounting seat 3. It can be understood that the "sway" mentioned here refers to the sway in a direction other than the first direction, not the movement of the support member 2 in the first direction.

[0092] Figures 8 - 11 Shows the mechanism for adjusting the clearance and friction of the steering column assembly 10 in the present invention. The mechanism for realizing this function mainly includes a support member 2, a mounting seat 3, and a clearance adjusting and friction reducing structure 7. When the steering column 1 is adjusted in the first direction, this mechanism can reduce the wear of the support member 2 and adjust the clearance between the support member 2 and the mounting seat 3.

[0093] In some embodiments of the present application, referring to Figures 8 - 11As shown in the figure, the clearance adjusting and friction reducing structure 7 includes a friction reducing gasket 8 and an elastic component 9. The friction reducing gasket 8 is installed on the support member 2, and the elastic component 9 is arranged between the friction reducing gasket 8 and the support member 2 to push the friction reducing gasket 8 against the mounting seat 3. During the implementation of the clearance adjustment function, the elastic component 9 and the friction reducing gasket 8 are paired and installed. When the support member 2 slides along the first direction on the mounting seat 3 and the clearance between the support member 2 and the mounting seat 3 changes, the deformation amount of the elastic component 9 with a pre-tightening force changes to adjust the clearance between the support member 2 and the mounting seat 3, and reduce the wobbling of the support member 2 relative to the mounting seat 3.

[0094] During the implementation of the friction reducing function, the friction reducing gasket 8 plays a major role. When the support member 2 slides along the first direction on the mounting seat 3, the support member 2 and the mounting seat 3 do not come into direct contact. The support member 2 and the friction reducing gasket 8 are relatively stationary, and the friction reducing gasket 8 is in frictional contact with the mounting seat 3, thereby reducing the wear of the support member 2 and avoiding the contact noise between the support member 2 and the mounting seat 3. In addition, the friction reducing gasket 8 is easy to replace. When the friction reducing gasket 8 is severely worn, a new friction reducing gasket 8 can be replaced.

[0095] In some embodiments of the present application, the friction reducing gasket 8 is processed from non-metallic materials, such as polytetrafluoroethylene, nylon, etc., and the mounting seat 3 is processed from metallic materials, such as steel, copper, etc. Therefore, when the non-metallic part and the metallic part rub against each other, the wear of the support member 2 is small, and the friction noise between the non-metallic part and the metallic part is also small, significantly reducing the noise when the support member 2 moves.

[0096] In some embodiments of the present application, both the support member 2 and the mounting seat 3 are processed from metallic materials, such as steel, copper, etc. By providing the friction reducing gasket 8, the problem of large vibration and noise generated by the contact between the metallic support member 2 and the metallic mounting seat 3 can be avoided.

[0097] In some embodiments of the present application, the elastic component 9 includes a disc spring gasket 91 or a spring.

[0098] In Figures 8 - 10 In the illustrated example, the elastic component 9 includes a disc spring gasket 91. The disc spring gasket 91 is an elastic gasket with a special shape and can be used to provide a pre-tightening force to adjust the clearance between the support member 2 and the mounting seat 3, and reduce the wobbling of the support member 2 relative to the mounting seat 3. Specifically, the disc spring gasket 91 is shaped like a disc, with a thicker middle and a thinner edge, and has good elastic deformation ability. The disc spring gasket 91 has a concave surface and a convex surface. When subjected to an axial pressure, the disc spring gasket 91 undergoes elastic deformation, causing the axial thickness of the disc spring gasket 91 to decrease. Within the thickness adjustment range of the disc spring gasket 91, the thickness of the disc spring gasket 91 is positively correlated with the applied axial pressure.

[0099] In some embodiments not shown in the figures, the elastic component 9 includes a spring, and the spring is used to provide a pre-tightening force to adjust the gap between the support member 2 and the mounting base 3, and reduce the wobbling of the support member 2 relative to the mounting base 3.

[0100] In some embodiments of the present application, referring to Figures 9 - 10 as shown, the support member 2 has a mounting hole, and the elastic component 9 is disposed in the mounting hole. One end of the elastic component 9 abuts against the support member 2, and the other end abuts against the friction-reducing gasket 8.

[0101] In Figures 8 - 10 the example shown, the elastic component 9 includes a plurality of disc-shaped gaskets 91. One end of the plurality of disc-shaped gaskets 91 abuts against the support member 2, and the other end abuts against the friction-reducing gasket 8. The plurality of disc-shaped gaskets 91 are stacked together in a specific placement order and have a pre-tightening force during installation. Taking the number of disc-shaped gaskets 91 as four as an example, the placement order of the four disc-shaped gaskets 91 can be: the concave surface of the first disc-shaped gasket is disposed opposite to the concave surface of the second disc-shaped gasket, the concave surface of the third disc-shaped gasket is disposed opposite to the concave surface of the fourth disc-shaped gasket, and the convex surface of the second disc-shaped gasket is disposed opposite to the convex surface of the third disc-shaped gasket; the placement order of the four disc-shaped gaskets can also be: the convex surface of the first disc-shaped gasket is disposed opposite to the convex surface of the second disc-shaped gasket, the convex surface of the third disc-shaped gasket is disposed opposite to the convex surface of the fourth disc-shaped gasket, and the concave surface of the second disc-shaped gasket is disposed opposite to the concave surface of the third disc-shaped gasket.

[0102] When the number of disc-shaped gaskets 91 is too small, the total deformation amount is small and the gap adjustment effect is poor; when the number of disc-shaped gaskets 91 is too large, the structure is complex and the assembly difficulty is great. In Figures 8 - 10 the example, the number of disc-shaped gaskets 91 is set to four, which can ensure a relatively small assembly difficulty and can provide a more appropriate deformation amount, and the gap adjustment effect is better.

[0103] In some embodiments of the present application, referring to Figures 8 - 10 as shown, the elastic component 9 further includes a snap ring 93 and a pressing piece 92. A snap ring groove is provided on the hole wall of the mounting hole, the snap ring 93 is clamped in the snap ring groove, the pressing piece 92 is located between the snap ring 93 and the disc-shaped gasket 91, the snap ring 93 abuts against the side of the pressing piece 92 facing away from the disc-shaped gasket 91, and the pressing piece 92 presses the plurality of disc-shaped gaskets 91 against the friction-reducing gasket 8.

[0104] In some embodiments of the present application, the friction-reducing gasket 8 has a limit protrusion 821, and the elastic component 9 is at least partially sleeved on the limit protrusion 821. The elastic component 9 is installed through the mounting hole on the support member 2 and the limit protrusion 821 on the friction-reducing gasket 8. In Figures 8 - 9In the illustrated example, the elastic component 9 includes a disc spring gasket 91, and the limiting protrusion 821 extends into the central hole of the disc spring gasket 91. In some embodiments not shown in the figure, the elastic component 9 includes a spring, and the limiting protrusion 821 extends into the central hole of the spring.

[0105] In some embodiments of the present application, a plurality of elastic components 9 are provided on the antifriction gasket 8. Referring to Figures 8 - 11 as shown, the elastic components 9 on each antifriction gasket 8 are multiple. The multiple elastic components 9 can fully adjust the gap between the support member 2 and the mounting seat 3. Referring to Figures 8 - 11 , in order to fully adjust the gap between the support member 2 and the mounting seat 3, three elastic components 9 are installed on a single antifriction gasket 8.

[0106] In some embodiments of the present application, the antifriction gasket 8 is disposed between the support member 2 and the mounting seat 3. The antifriction gasket 8 includes a first gasket section 81 and a second gasket section 82. The first gasket section 81 and the second gasket section 82 are connected to each other, and the extending directions of the first gasket section 81 and the second gasket section 82 are different.

[0107] Referring to Figures 5 - 6 、 Figures 8 - 9 as shown, the mounting seat 3 includes a seat body main body 34 and seat body limiting platforms 35 located on both sides of the seat body main body 34. The seat body limiting platforms 35 are connected to the seat body main body 34. A guiding groove 31 is formed between the seat body limiting platforms 35 and the seat body main body 34. The support member 2 includes a support main body 22 and a guide rail 21. The support main body 22 and the guide rail 21 are connected to each other. The guide rail 21 is located in the guiding groove 31, and the support main body 22 is located outside the guiding groove 31. The first gasket section 81 is located between the guide rail 21 and the seat body limiting platform 35, and the second gasket section 82 is located between the support main body 22 and the seat body limiting platform 35. The elastic component 9 is disposed between the second gasket section 82 and the support main body 22. The inner side surface of the seat body limiting platform 35 is in sliding contact with the first gasket section 81, and the outer end surface of the seat body limiting platform 35 is in sliding contact with the second gasket section 82.

[0108] Referring to Figures 1 - 2 、 Figure 6 、 Figure 13 as shown, the support main body 22 is connected to the steering column 1. Specifically, the support main body 22 includes a mounting support arm 23, and the mounting support arm 23 is connected to the housing 11 of the steering column 1.

[0109] In some embodiments of the present application, the guiding groove 31 is a dovetail groove, the guide rail 21 is a dovetail guide rail, the antifriction gasket 8 is fixed to the dovetail guide rail, and the antifriction gasket 8 is in sliding fit with the dovetail groove.

[0110] In some embodiments of the present application, the first gasket section 81 is fixed to the guide rail 21.

[0111] In some embodiments of the present application, referring to Figures 8 - 9 as shown, one of the antifriction gasket 8 and the support member 2 has a convex structure 811, and the other has a groove structure. The convex structure 811 is fitted with the groove structure in an embedded manner to realize the connection and fixation of the antifriction gasket 8 and the support member 2. The number of the convex structures 811 can be one or more, and the groove structure is in one-to-one correspondence with the convex structure 811 for fitting. For example, as Figure 8 shown, the antifriction gasket 8 has the convex structure 811, and the support member 2 has the groove structure, and the number of the convex structures 811 is two.

[0112] In some embodiments of the present application, one of the first section 81 of the gasket and the guide rail 21 has a convex structure 811, and the other has a groove structure. The convex structure 811 is fitted with the groove structure in an embedded manner to realize the connection and fixation of the first section 81 of the gasket and the guide rail 21. The number of the convex structures 811 can be one or more, and the groove structure is in one-to-one correspondence with the convex structure 811 for fitting. For example, as Figure 8 shown, the first section 81 of the gasket has the convex structure 811, and the guide rail 21 has the groove structure, and the number of the convex structures 811 is two.

[0113] In some embodiments of the present application, referring to Figures 8 - 9 as shown, the second section 82 of the gasket has a limiting projection 821, and the elastic component 9 is at least partially sleeved on the limiting projection 821. The elastic component 9 is installed on the limiting projection 821 on the second section 82 of the gasket through the mounting hole on the support member 2. In Figures 8 - 9 the example shown, the elastic component 9 includes a disc spring 91, and the limiting projection 821 extends into the central hole of the disc spring 91. In some embodiments not shown in the figure, the elastic component 9 includes a spring, and the limiting projection 821 extends into the central hole of the spring.

[0114] In some embodiments of the present application, the antifriction gasket 8 is disposed between the support member 2 and the mounting seat 3, and the antifriction gasket 8 is in contact with at least a part of the support member 2. In the first direction, the antifriction gasket 8 and the support member 2 at least partially overlap.

[0115] In some embodiments of the present application, referring to Figure 10As shown, in the first direction, the length of the antifriction gasket 8 is equal to that of the support member 2, both being L0. If the length of the antifriction gasket 8 is less than that of the support member 2, there is a risk of contact between the support member 2 and the mounting seat 3. If the length of the antifriction gasket 8 is greater than that of the support member 2, the material of the antifriction gasket 8 is wasted. By setting the length of the antifriction gasket 8 to be equal to that of the support member 2, the antifriction gasket 8 can comprehensively protect the support member 2, prevent the support member 2 from contacting the mounting seat 3, reduce the wear of the support member 2, and also avoid the contact noise between the support member 2 and the mounting seat 3. At the same time, the material of the antifriction gasket 8 is not wasted.

[0116] In this application, by adding the antifriction gasket 8 and the elastic component 9 between the support member 2 and the mounting seat 3, on the one hand, the gap between the support member 2 and the mounting seat 3 can be adjusted, the overall stiffness of the steering column assembly 10 can be improved, and the vibration of the steering column 1 can be reduced; using the antifriction gasket 8 made of non-metallic material can also improve the problems of large sliding friction wear and contact noise caused by the contact of two metal parts, and achieve the functions of antifriction and noise reduction.

[0117] In some embodiments of the present application, gap-adjusting antifriction structures 7 are provided between both sides of the support member 2 and the mounting seat 3. Referring to Figures 8 - 11 , antifriction gaskets 8 are symmetrically arranged on both sides of the support member 2, and a plurality of elastic components 9 are provided on each antifriction gasket 8. The plurality of elastic components 9 on each antifriction gasket 8 are spaced apart in the first direction. Thus, when the support member 2 moves in the first direction, the plurality of elastic components 9 participate in the gap adjustment, and the gap adjustment effect is good.

[0118] In some embodiments of the present application, referring to Figures 1 - 4 、 Figure 12 As shown, the steering column assembly 10 further includes a collapse structure 4. The nut slider 522 is connected to the support member 2 through the collapse structure 4. Specifically, the nut slider 522 is connected to the collapse structure 4, and the collapse structure 4 is connected to the support member 2. For example, the nut slider 522 is connected to the collapse structure 4 by screws, and the collapse structure 4 is connected to the support member 2 by screws. The collapse structure 4 is configured to enable the support member 2 to move relative to the nut slider 522 when the steering column 1 is axially impacted and collapses and deforms.

[0119] In addition to the support member 2, the mounting seat 3, and the driving device 5, the mechanism for realizing the height adjustment and storage functions of the steering column 1 further includes a collapse structure 4. In addition, after setting the collapse structure 4, the steering column 1 of the present application can also have a collapse function.

[0120] In some embodiments of the present application, referring to Figures 1 - 4 、 Figure 12As shown, the collapse structure 4 includes a collapse energy absorber 43 and a connecting member 42. One end of the collapse energy absorber 43 is connected to the support member 2, and the other end is connected to the nut slider 522. The connecting member 42 is connected to the support member 2 and is also connected to the nut slider 522. When the axial impact force received by the steering column 1 cuts off the connection between the connecting member 42 and the support member 2, the steering column 1 is adapted to drive the support member 2 to move so that the collapse energy absorber 43 collapses and deforms. When the collapse energy absorber 43 deforms, it can absorb the impact energy.

[0121] In some embodiments of the present application, the collapse structure 4 further includes a collapse mounting seat 41. One end of the collapse energy absorber 43 is connected to the support member 2 through the collapse mounting seat 41, and the connecting member 42 is connected to the support member 2 through the collapse mounting seat 41. The collapse mounting seat 41 is mounted on the support member 2. One end of the collapse energy absorber 43 is connected to the collapse mounting seat 41. In this way, the said one end of the collapse energy absorber 43 is connected to the support member 2 through the collapse mounting seat 41. The connecting member 42 is connected to the collapse mounting seat 41, and the collapse mounting seat 41 is mounted on the support member 2. Therefore, the connecting member 42 is connected to the support member 2 through the collapse mounting seat 41. The connecting member 42 is also connected to the nut slider 522.

[0122] When the axial impact force received by the steering column 1 cuts off the connection between the connecting member 42 and the collapse mounting seat 41, the steering column 1 drives the collapse mounting seat 41 to move through the support member 2, and when the collapse mounting seat 41 moves, it drives the collapse energy absorber 43 to deform.

[0123] In other words, when the steering column 1 moves downward under the axial impact force, the steering column 1 drives the collapse mounting seat 41 to move downward through the support member 2 so that the collapse mounting seat 41 is separated from the connecting member 42, and when the collapse mounting seat 41 moves downward, it drives the collapse energy absorber 43 to deform.

[0124] The collapse mounting seat 41 and the support member 2 can be connected by a second fastener. For example, referring to Figure 12 As shown, the collapse mounting seat 41 is provided with a first fixing hole 411, and the second fastener passes through the first fixing hole 411 and is fastened to the support member 2. The number of the first fixing holes 411 can be one or more.

[0125] One end of the collapse energy absorber 43 and the collapse mounting seat 41 can be connected as an integral part, and the other end of the collapse energy absorber 43 and the nut slider 522 can be connected by a third fastener. For example, referring to Figure 12 As shown, the collapse energy absorber 43 is provided with a second fixing hole 433, and the third fastener passes through the second fixing hole 433 and the nut slider 522.

[0126] The connecting member 42 and the collapsible mounting seat 41 are connected by a rivet 44. When the axial impact force on the steering column 1 exceeds the breaking force of the rivet 44, the rivet 44 is sheared, and the collapsible mounting seat 41, the support member 2, and the steering column 1 can move downward synchronously.

[0127] The number of rivets 44 can be multiple. For example, in Figure 12 the illustrated example, there are four rivets 44, and the four rivets 44 are arranged at the four vertices of a quadrilateral, which can be a rectangle, a square, a rhombus, a trapezoid, etc.

[0128] In some embodiments of the present application, referring to Figure 12 as shown, the collapsible energy-absorbing member 43 is a strip structure, and a trigger member 45 is provided on the collapsible mounting seat 41. When the collapsible mounting seat 41 moves downward, the trigger member 45 presses the collapsible energy-absorbing member 43 to separate the collapsible energy-absorbing member 43 from the collapsible mounting seat 41. The shape of the trigger member 45 is not limited. For example, the trigger member 45 can be configured as a block structure, a rod structure, etc.

[0129] In some embodiments of the present application, the collapsible energy-absorbing member 43 is at least partially configured as a "U" shape. The collapsible energy-absorbing member 43 includes a first section of belt 431 and a second section of belt 432. The first section of belt 431 and the second section of belt 432 are connected to each other. The first section of belt 431 is connected to the collapsible mounting seat 41, and the second section of belt 432 is connected to the nut slider 522. The width L2 of the second section of belt 432 is greater than the width L1 of the first section of belt 431.

[0130] The collapsible energy-absorbing member 43 is bent into a U shape. Its first section of belt 431 is narrow and long, and the second section of belt 432 is wide and short. Specifically, the first section of belt 431 is bent into a U shape.

[0131] In some embodiments of the present application, the second section of belt 432 and the connecting member 42 are fastened to the nut slider 522 by a common fastener (i.e., the third fastener).

[0132] In some embodiments of the present application, the nut slider 522 includes a nut body 5221 and a restraint plate 5222. The restraint plate 5222 is connected to the nut body 5221. Both the collapsible energy-absorbing member 43 and the connecting member 42 are connected to the restraint plate 5222. Two second fixing holes 433 are provided on the second section of belt 432 and are connected to the restraint plate 5222 by the third fastener.

[0133] When a collision occurs in vehicle 100, the impact force received by the steering column 1 will trigger the collapsible structure 4. The steering column 1 quickly moves in the direction of F2 driven by the support member 2. The rivet 44 between the connecting member 42 and the collapsible mounting seat 41 in the collapsible structure 4 is cut off. Then, the trigger member 45 on the collapsible mounting seat 41 drives the collapsible energy absorber 43 to deform, converting the collision energy into the deformation energy of the mechanism itself, thereby reducing the impact on the driver.

[0134] In some embodiments of the present application, referring to Figures 1 - 3 As shown, the steering column assembly 10 further includes a motor 6. The motor 6 is connected to the steering column 1. The axis of the output shaft of the motor 6 has an angle with the axis of the steering column 1, and the angle is greater than 0. Thus, the motor 6 and the steering column 1 are arranged in an interleaved manner, increasing the movable space for the axial adjustment of the steering column 1, improving the utilization rate of the axial space within the limited in-vehicle layout space, significantly increasing the storage and adjustment range of the steering column 1, and improving the space utilization rate for the storage layout in the whole vehicle.

[0135] The angle between the axis of the output shaft of the motor 6 and the axis of the steering column 1 can be 90°, or it can be an acute angle, for example, an acute angle not less than 30°.

[0136] The steering column assembly 10 is a steer-by-wire steering column assembly. The main function of the motor 6 is to simulate the road feel in a traditional hydraulic power steering system and provide real steering force feedback to the driver. This force feedback is very important for the driver to perceive the driving state and road conditions of the vehicle 100, and helps to improve driving safety and comfort.

[0137] The motor 6 simulates the steering force related to the driving speed, steering angle, and road conditions of the vehicle 100 by precisely controlling the torque output of the motor. For example, when driving at high speed, the motor 6 can increase the steering force to make the steering more stable; when driving at low speed, the motor 6 can reduce the steering force to make the steering more lightweight.

[0138] By simulating the real road feel, the motor 6 can improve driving comfort and confidence. The driver can perceive the driving state of the vehicle 100 according to the change of the steering force, and thus make more accurate driving operations, which is beneficial to enhancing the driving experience.

[0139] The motor 6 can dynamically adjust the magnitude of the steering assist according to different driving conditions and driving modes. This adjustment helps to optimize the steering performance and adapt to different driving needs.

[0140] The motor 6 and the steering column 1 can be directly connected or indirectly connected.

[0141] For example, in some embodiments, the motor 6 is fixed to the steering column 1 through a fixing base. The fixing base is generally designed to have a structure that can closely cooperate with the steering column 1, ensuring that the motor 6 is stable and reliable during operation and will not loosen due to the vibration during the driving of the vehicle 100.

[0142] In some embodiments of the present application, the steering column assembly 10 further includes a speed reduction mechanism. The motor 6 and the steering column 1 are indirectly connected through the speed reduction mechanism. The speed reduction input end of the speed reduction mechanism is connected to the power output end of the motor 6, and the speed reduction output end of the speed reduction mechanism is connected to the power input end of the steering column 1. This connection method enables the power of the motor 6 to be transmitted to the steering column 1 through the speed reduction mechanism, realizing the power assist and feel simulation of the steering wheel. The speed reduction mechanism can be installed inside the steering column 1, so that the steering column 1 can protect the speed reduction mechanism, and the speed reduction mechanism does not occupy too much external space of the steering column 1, making the overall structure of the steering column assembly 10 more compact.

[0143] In some embodiments of the present application, the speed reduction mechanism is a worm and worm gear mechanism. The motor 6 is connected to the steering column 1 through the worm and worm gear mechanism. The worm and worm gear mechanism includes a worm wheel and a worm. The output shaft of the motor 6 is connected to the worm, and the worm meshes with the worm wheel fixed on the steering column 1. This connection method can achieve a large reduction ratio, and at the same time has a compact structure, and can effectively transmit power and simulate different feels.

[0144] In some embodiments of the present application, the speed reduction mechanism is a gear reduction mechanism. The gear reduction mechanism includes a plurality of meshing gears. The structure of gear reduction is relatively common and will not be elaborated here.

[0145] In some embodiments of the present application, the motor 6 is electrically connected to the control device of the vehicle 100. The control device controls the power output of the motor 6 according to the driving state of the vehicle 100 and the operation signals of the driver, so as to achieve different feel simulation effects.

[0146] In some embodiments of the present application, the control device receives signals from sensors of the vehicle 100, such as a steering angle sensor, a torque sensor, etc., and adjusts the output torque of the motor 6 according to these signals. For example, when the vehicle 100 is driving on a bumpy road surface, the sensor will detect the unevenness of the road surface, and the control device adjusts the output of the motor 6 according to these signals, so that the driver can feel the corresponding road feel.

[0147] In some embodiments of the present application, the motor 6 needs to be connected to the power supply system of the vehicle 100 to obtain a stable power supply. For example, it can be connected to the battery or generator of the vehicle 100 through a dedicated power line to ensure that the motor can obtain sufficient power support during operation.

[0148] The steering column assembly 10 of the present application has functions such as height adjustment of the steering column 1, long-stroke storage of the steering column 1, and crash energy absorption and protection, and realizes functions such as noise reduction, friction reduction, and clearance adjustment during the stroke. The steering column assembly 10 proposed in the present application is structurally compact and has rich functions, meeting the requirements of electrification and intelligent design of the steering column 1.

[0149] As an advanced steering technology, the Steer-by-Wire system has gradually replaced the traditional mechanical steering system. This system realizes steering operations through electronic signals rather than mechanical connections, and has higher flexibility and intelligence.

[0150] With the improvement of the automation and intelligence of the vehicle 100, the driver's demand for the interior space of the vehicle is also increasing. In order to optimize the interior layout and improve the driver's freedom of movement, the steering column 1 needs to have a longer telescopic stroke to quickly store the steering wheel in the autonomous driving or driverless mode. This storage function can not only provide more legroom for the driver but also support the versatility of the vehicle 100 (such as shared travel, unmanned delivery, etc.).

[0151] The steering column assembly 10 of the present invention is a steering column assembly 10 with a storage function for a Steer-by-Wire system of a vehicle 100, including a steering column 1, a support member 2, a mounting seat 3, a crash structure 4, a driving device 5, a motor 6, and a clearance adjustment and friction reduction structure 7. It can perfectly realize the storage function of the steering wheel within a limited layout space. Among them, the lead screw 521 is combined with the guide groove 31 and the guide rail 21 to realize the axial long-stroke adjustment function of the steering column 1, and the clearance adjustment and friction reduction structure 7 ensures the stability and noise reduction of the storage stroke. The crash structure 4 can absorb collision energy. In summary, it meets the intelligent and electrified requirements of the Steer-by-Wire column 1 adjustment.

[0152] In some embodiments, the Steer-by-Wire system may include a control device and an execution device. The execution device is electrically connected to the control device. The control device is used to convert the steering angle information of the steering wheel into an execution signal for output, and the execution device drives the wheels to steer according to the execution signal.

[0153] Refer to Figure 14 As shown, the steering system 20 according to the second aspect embodiment of the present application includes the above-mentioned steering column assembly 10.

[0154] In the steering system 20 according to the embodiment of the present application, the adjustment mechanism in the steering column assembly 10 directly drives the steering column 1 to move in the first direction to realize the position adjustment of the steering column 1 in the first direction, and the position adjustment range of the steering column is relatively large.
