[0002] The steering column of a vehicle is used to transmit the torque of the vehicle steering wheel to realize the vehicle steering device. With the advent of the era of autonomous driving, in order to provide a wider seat free rotation space and driving space for the driver, it is necessary to adjust the layout and function of the steering wheel.

[0003] In the related art, in order to realize the storage function of the steering wheel, the steering column generally includes an outer sleeve, a movable cylinder inserted into the outer sleeve, and a steering wheel fixed shaft rotatably inserted into the movable cylinder and axially moving synchronously with the movable cylinder. The steering wheel fixed shaft is connected to the steering wheel. Through a driving mechanism passing through the outer sleeve and connected to the movable cylinder, the movable cylinder is controlled to move axially along the outer sleeve to realize the telescopic function of the steering wheel. However, in this implementation, if it is necessary to change the moving range of the steering wheel fixed shaft, it is necessary to redesign the steering column and the driving mechanism.

[0040] The following will describe in detail the specific embodiments of the present disclosure with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only for the purpose of illustrating and explaining the present disclosure, and are not intended to limit the present disclosure.

[0041] In the present disclosure, unless otherwise stated, "inner" and "outer" refer to the inside and outside of the contour of the corresponding component. In addition, the terms "first" and "second" used in the present disclosure are used to distinguish one element from another element, and do not have an order or importance. In addition, when the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements.

[0042] According to Figures 1 to 4 As shown, a first aspect of the present disclosure provides a steering device, which may include a mounting mechanism 1 and a steering column 3. The mounting mechanism 1 may include a base body 10. For example, the base body 10 may be connected to the instrument crossbeam of the vehicle or other structures of the vehicle. Those skilled in the art can make adjustments according to the actual needs, and the present disclosure does not make specific limitations in this regard. The steering column 3 may include a housing 30 and a mounting shaft 32. The mounting shaft 32 is rotatably mounted on the housing 30 about its own axis, and the mounting shaft 32 is used to connect to the steering wheel so that the torque generated when the steering wheel rotates can be transmitted to the mounting shaft 32. Among them, one of the mounting mechanism 1 and the steering column 3 includes a driving member 22, and the other includes a guiding member 11. One of the driving member 22 and the guiding member 11 is connected to the housing 30, and the other is connected to the base body 10. For example, the mounting mechanism 1 may include the guiding member 11, the steering column 3 may include the driving member 22, the guiding member 11 may be connected to the base body 10, and the driving member 22 may be connected to the housing 30. The present disclosure is not limited to this. The driving member 22 and the guiding member 11 are in transmission connection, so that the steering column 3 can reciprocate relative to the mounting mechanism 1 to realize the telescopic function of the steering wheel.

[0043] Through the above technical solution, the mounting mechanism 1 and the steering column 3 are provided to cooperate. One of the mounting mechanism 1 and the steering column 3 includes a driving member 22, and the other includes a guiding member 11. The driving member 22 is used to drive the steering column 3 to reciprocate relative to the mounting mechanism 1 along the guiding member 11, which simplifies the structure. The design of the mounting mechanism 1 and the steering column 3 is split. Under the different requirements of different vehicle models or different vehicle manufacturers for the telescopic distance of the steering wheel, there is no need to redesign the steering column, and only the structure of the mounting mechanism needs to be designed and changed, which can effectively reduce the economic cost and improve the applicable range of the steering column.

[0044] Among them, the base body 10 may be constructed as a mounting plate or other adaptable structures, and the present disclosure is not limited to this.

[0045] In some implementable ways, for example, refer to Figure 1 andFigure 2 As shown, the steering device may further include a haptic simulation motor 31 disposed on the housing 30. The haptic simulation motor 31 is connected to the mounting shaft 32. The haptic simulation motor 31 can enable the vehicle to enter a by-wire mode or a game mode according to the actual application requirements of the user. Among them, for the specific structure and function of the haptic simulation motor 31, those skilled in the art can consult and retrieve existing literature, and the present disclosure will not elaborate herein.

[0046] In some implementable ways, for example, referring to Figure 1 and Figure 2 As shown, the driving member 22 may be disposed on the housing 30 and includes a driving motor 220 and a transmission member 221. The guiding member 11 may be disposed on the base body 10 and includes a mating member 110 extending along the first direction X. The driving motor 220 is connected to the mating member 110 through the transmission member 221 to drive the steering column 3 to move along the first direction X. By disposing the driving member 22 on the housing 30 and the guiding member 11 on the base body 10, when it is necessary to adjust the moving stroke of the steering column, only the base body 10 and the guiding member 11 need to be adjusted, and there is no need to redesign the steering column, which can effectively reduce the economic cost and improve the adaptability of the steering device of the present disclosure.

[0047] Optionally, the transmission member 221 may include a transmission gear set, and the mating member 110 may include a lead screw or a rack. The lead screw or the rack is connected to the base body 10, and the driving motor 220 is connected to the lead screw or the rack through the transmission gear set.

[0048] Among them, the transmission gear set may include a worm and a worm gear connected to each other. The worm is threadedly sleeved on the lead screw, and the worm gear is coaxially connected to the driving motor 220 to drive the steering column 3 through the transmission mode of the worm and the worm gear. It should be noted that in this embodiment, both ends of the lead screw are fixedly connected to the base body 10. The transmission gear set may also include a gear connected to the output end of the driving motor 220, and the gear meshes with the rack. The present disclosure does not make specific limitations on this.

[0049] The limitation on the installation positions of the driving member 22 and the guiding member 11 in the present disclosure is only for the present disclosure. The driving member 22 may also be disposed on the base body 10, and the guiding member 11 may also be disposed on the housing 30. The present disclosure does not make specific limitations on this, as long as the function of driving the steering column 3 to move can be achieved, and those skilled in the art can make adaptive adjustments according to the actual situation.

[0050] In other implementable ways not shown in the figures, for example, the driving member 22 can be arranged on the base body 10 and includes a driving motor 220 and a mating member 110 extending along the first direction X. The mating member 110 can be configured as a lead screw. The guiding member 11 can be arranged on the housing 30 and includes a transmission member 221. The transmission member 221 can be configured as a slider threadedly connected to the lead screw. The driving motor 220 is used to drive the lead screw to rotate so that the transmission member 221 can drive the steering column 3 to move, and the above-mentioned transmission function can also be realized. The present disclosure is not limited thereto, and those skilled in the art can make adaptive adjustments according to the actual situation.

[0051] Next, taking the driving member 22 that can be arranged on the housing 30 and includes a driving motor 220 and a transmission member 221, and the guiding member 11 that can be arranged on the base body 10 and includes a mating member 110 extending along the first direction X, and the driving motor 220 is connected to the mating member 110 through the transmission member 221 to drive the steering column 3 to move along the first direction X as an example, in some implementable ways, for example, referring to Figures 1 to 3 As shown, the driving member 22 can further include an installation shell 222 covering the transmission gear set. The installation shell 222 has a through hole 222a for the lead screw to pass through. The installation shell 222 is used to protect the transmission gear set to prevent dust and other pollutants in the external environment from adhering to the transmission gear set, thereby affecting the normal operation of the transmission gear set.

[0052] In some implementable ways, for example, referring to Figures 1 to 4 As shown, the number of the mating members 110 and the transmission members 221 is the same and both are multiple. The driving motor 220 is connected to at least one transmission member 221 to be connected to at least one mating member 110. For example, the number of the mating members 110 and the transmission members 221 can be one. The driving motor 220 is connected to the mating member 110 through the transmission member 221 to drive the transmission member 221 to move along the mating member 110 in the first direction X. The number of the mating members 110 and the transmission members 221 can also be two. The driving motor 220 can adopt a double-headed motor. The two output ends of the double-headed motor are respectively connected to the two transmission members 221, and the two transmission members 221 are respectively connected to the two mating members 110. By adjusting the number of the mating members 110 and the transmission members 221 and setting multiple mating members 110 and transmission members 221, the stability and safety of the transmission process can be effectively improved.

[0053] Of course, the number of the driving motors 220 can also correspond to the number of the transmission members 221. For example, the number of the driving motors 220 can also be two, and the two driving motors 220 are respectively connected to the two transmission members 221. The present disclosure does not make specific limitations thereto, and those skilled in the art can make adaptive adjustments according to the actual situation.

[0054] In some implementable ways, for example, with reference to Figure 1 and Figure 2 As shown, one of the mounting mechanism 1 and the steering column 3 may include a guiding portion 111, and the other may include a mating portion 211. One of the guiding portion 111 and the mating portion 211 is disposed on the base 10, and the other is disposed on the housing 30. The guiding portion 111 and the mating portion 211 are slidably engaged to guide the movement of the steering column 3 relative to the base 10. By providing the guiding portion 111 and the mating portion 211, the steering column 3 can be made more stable during movement.

[0055] Optionally, the guiding portion 111 may include a chute, and the mating portion 211 may include a first slider slidably connected to the chute. Further, the guiding portion 111 may also include a sliding rod, and the mating portion 211 may also include a second slider slidably sleeved on the sliding rod. Of course, it can be understood that the guiding portion 111 may include a chute, and the mating portion 211 may include a first slider slidably connected to the chute, or the guiding portion 111 may also include a sliding rod, and the mating portion 211 may also include a second slider slidably sleeved on the sliding rod. The present disclosure does not make specific limitations in this regard, and those skilled in the art can make adaptive adjustments according to actual needs.

[0056] The structural limitations of the guiding portion 111 and the mating portion 211 in the present disclosure are only for the present disclosure. The structures of the guiding portion 111 and the mating portion 211 can be adaptively adjusted according to actual needs. For example, the guiding portion 111 may be configured as a slide rail, and the mating portion 211 may be configured as a slider or a sliding rod slidably connected to the slide rail. The present disclosure does not make specific limitations in this regard, as long as its function can be achieved.

[0057] The number of the guiding portion 111 and the mating portion 211 can be adaptively adjusted according to actual needs. For example, the number of the guiding portion 111 and the mating portion 211 may correspond to the number of the mating members 110 and the transmission members 221. The number of the guiding portion 111 and the mating portion 211, and the number of the mating members 110 and the transmission members 221 can both be two. The two guiding portions 111 may be located between the two mating members 110, and the two mating portions 211 may be located between the two transmission members 221. Figure 4 An embodiment in which the guiding portion 111 includes a chute and the chute is located between the two mating portions 211 is exemplarily shown in

[0058] In some implementable ways, for example, with reference to Figure 1 and Figure 2 As shown, the guiding portion 111 or the mating portion 211 on the housing 30 is integrally formed on the housing 30 to reduce the technological process during processing and effectively improve stability.

[0059] In the steering device provided in the first aspect of the present disclosure, the steering column 3 can adopt an existing steering column. For example, the housing 30 can include an outer sleeve and a movable cylinder axially movably inserted into the outer sleeve. The mounting shaft 32 is rotatably inserted into the movable cylinder and axially moves synchronously with the movable cylinder. Thus, the adjustment range of the mounting shaft 32 of the steering wheel can be adjusted doubly, that is, it can be adjusted through the mounting mechanism 1, or through the relative position of the outer sleeve and the movable cylinder, or it can also be adjusted by both methods simultaneously to accelerate the adjustment speed. The present disclosure is not limited thereto.

[0060] In addition, the steering column 3 can also adopt, for example, the steering column provided in the second aspect of the present disclosure.

[0061] For example, the second aspect of the present disclosure provides a steering column 3, which can include a housing 30 and a mounting shaft 32. The mounting shaft 32 is used to connect the steering wheel. The mounting shaft 32 is rotatably connected to the housing 30 about its own axis and axially limited in the housing 30, so that the mounting shaft 32 cannot move axially along the housing 30; the steering column 3 can also include one of a driving member 22 and a guiding member 11 provided on the housing 30. For example, the steering column 3 can include the driving member 22 provided on the housing 30, and the driving member 22 is used for driving connection with the guiding member 11 of the mounting mechanism 1. Or, the steering column 3 can include the guiding member 11 provided on the housing 30, and the guiding member 11 is used for connection with the driving member 22 of the mounting mechanism 1, so that the steering column 3 can reciprocate relative to the mounting mechanism 1. The present disclosure does not make specific limitations thereto. Among them, the mounting mechanism 1 can be connected to the instrument crossbeam of the vehicle; of course, for the mounting positions of the driving member 22 and the guiding member 11, those skilled in the art can make adaptive adjustments according to actual needs. The present disclosure is not limited thereto.

[0062] Through the above technical solution, the mounting shaft 32 is configured not to move axially along the housing 30, so that during the movement of the steering column 3, the mounting shaft 32 will not generate a displacement relative to the steering column 3, which can effectively shorten the axial length of the steering column 3. For example, compared with the prior art, the outer sleeve can be cancelled, or the outer sleeve and the movable cylinder can be fixedly connected and the length of the outer sleeve can be reduced. Thus, the occupied space of the steering column 3 can be significantly reduced. For the occupied space reduced in the above manner, those skilled in the art can change the length of the guiding member 11 along the first direction X according to actual needs, so that the steering column 3 can obtain a larger moving stroke.

[0063] Among them, between the mounting shaft 32 and the housing 30, the mounting shaft 32 can be rotatably inserted into the housing 30 and axially limited to the housing 30 through any suitable structure. For example, the mounting shaft 32 can be mounted on the housing 30 by sleeving a bearing, and the bearing and the mounting shaft 32 can achieve axial positioning through the cooperation of, for example, a snap ring and a shoulder, etc. The present disclosure is not limited thereto.

[0064] In some implementable ways, for example, referring to Figure 1 and Figure 2 as shown, the driving member 22 can be arranged on the housing 30 and includes a driving motor 220 and a transmission member 221. The driving motor 220 is connected to the guiding member 11 of the mounting mechanism 1 through the transmission member 221, so that the driving motor 220 can drive the transmission member 221 to drive the steering column 3 to move along the guiding member 11 in the first direction X to realize the telescopic function of the steering wheel. For example, the transmission member 221 can be configured as a worm and worm gear, the guiding member 11 can be configured as a lead screw, or the transmission member 221 can be configured as a gear, and the guiding member 11 can be configured as a rack. The present disclosure is not limited thereto, and those skilled in the art can make adaptive adjustments according to actual needs.

[0065] In some implementable ways, for example, referring to Figure 1 and Figure 2 as shown, the steering column 3 can further include at least one of a guiding portion 111 and a mating portion 211 arranged on the housing 30. The guiding portion 111 is used for sliding cooperation with the mating portion 211 of the mounting mechanism 1, or the mating portion 211 is used for sliding cooperation with the guiding portion 111 of the mounting mechanism 1 to guide the steering column 3 to move relative to the mounting mechanism 1. Arranging the guiding portion 111 and the mating portion 211 can further enhance the stability of the steering column 3 during movement. For example, the guiding portion 111 can be configured as a slider or a slide bar, the mating portion 211 can be configured as a slide rail or a slide groove, or the guiding portion 111 can be configured as a slide rail or a slide groove, and the mating portion 211 can be configured as a slider or a slide bar. The present disclosure is not limited thereto, and those skilled in the art can make adaptive adjustments according to actual needs.

[0066] In some implementable ways, for example, referring to Figure 1 and Figure 2 as shown, the steering column 3 can further include a feel simulation motor 31. The feel simulation motor 31 is arranged on the housing 30 and connected to the mounting shaft 32.

[0067] In some implementable ways, for example, referring to Figure 1 and Figure 2As shown, the housing 30 may include a sleeve 301 and a shell 302, the sleeve 301 is connected to one side of the shell 302, the feel simulation motor 31 is connected to the other side of the shell 302, the first end of the mounting shaft 32 is used to connect to the steering wheel, the second end of the mounting shaft 32 extends into the sleeve 301 or the shell 302 to connect to the feel simulation motor 31, and the driving member 22 or the guide member 11 may be arranged on the shell 302. The driving member 22 or the guide member 11 is arranged on the shell 302 between the mounting shaft 32 and the feel simulation motor 31, which can ensure that the steering wheel obtains a longer moving distance during the movement process, wherein the feel simulation motor 31 can be connected to the mounting shaft 32 in any suitable manner, for example, the feel simulation motor 31 can be connected to the mounting shaft 32 in a direct drive manner, or can be connected to the mounting shaft 32 through, for example, a speed reduction mechanism, and the speed reduction mechanism can be, for example, a worm gear mechanism, a planetary gear mechanism, or a belt drive, etc., and the present disclosure is not limited thereto.

[0068] It should be noted that a pre-pressing mechanism may be provided between the guide portion 111 and the mating portion 211 mentioned above. For example, the pre-pressing mechanism may be provided between the mating surfaces of the guide portion 111 and the mating portion 211 to avoid a gap between the guide portion 111 and the mating portion 211 during the mating process, thereby affecting the stability of the moving process. For example, the guide portion 111 may be configured as a slide groove, the mating portion 211 may be configured as a slider, the pre-pressing mechanism may be configured as a plate body and an elastic member connected to the plate body, the elastic member may be a spring, the plate body is slidably connected to the slide groove, and the end of the elastic member facing away from the plate body is connected to the slider, so that the stability between the guide portion 111 and the mating portion 211 can be further enhanced.
