DETAILED DESCRIPTION

[0037] The exemplary embodiments will be described in detail herein with reference to the attached drawings. In the following description, the same numbers are used to indicate the same or similar components. The embodiments described in the following exemplary embodiments do not represent all the implementations consistent with the present disclosure. Instead, they only represent examples of devices and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

[0038] In the present disclosure, the terms "first", "second", and the like used in the present disclosure are used to distinguish one element from another element, without having sequential and important nature, wherein "inner", "outer" are relative to the "inner", "outer" of the corresponding component itself, and in the following description, the same reference signs in different drawings represent the same or similar elements, unless otherwise explained. The above definition is only used to explain and illustrate the present disclosure, and should not be understood as a limitation of the present disclosure.

[0039] According to the exemplary embodiments of the present disclosure, referring to Figures 1 to 6 A steering wheel adjusting device is provided, comprising: a steering column assembly 100, comprising a connecting shaft 1, the connecting shaft 1 being used for connecting with a steering wheel of a vehicle; an axial adjusting assembly 200, comprising a primary adjusting structure 201 and a secondary adjusting structure 202, the primary adjusting structure 201 and the secondary adjusting structure 202 being used for adjusting the position of the steering column assembly 100 in the axial direction of the connecting shaft 1; and a feel simulation motor 10, in transmission connection with the connecting shaft 1.

[0040] The technical scheme provided by the embodiments of the present disclosure can include the following beneficial effects: in the steering wheel adjusting device provided by the present disclosure, since the axial adjusting assembly 200 comprises the primary adjusting structure 201 and the secondary adjusting structure 202, and the primary adjusting structure 201 and the secondary adjusting structure 202 are used for adjusting the position of the steering column assembly 100 in the axial direction of the connecting shaft 1, therefore, the two-stage adjustment of the axial position of the steering column assembly can be realized by the axial adjusting assembly 200, so that the adjustment stroke of the steering column assembly 100 in the axial direction of the connecting shaft 1 is longer, that is, the adjustment stroke of the steering wheel in the axial direction of the connecting shaft 1 is longer, which improves the user experience, and in addition, the feel simulation motor 10 is provided, the feel simulation motor 10 is in transmission connection with the connecting shaft 1, which is conducive to the integrated design of the steering wheel adjusting device and further improves the user experience.

[0041] In addition, the two-stage adjustment by the axial adjusting assembly 200 can realize the folding storage of the steering wheel, and it is convenient to selectively use the steering wheel according to the use requirement, specifically, when the driver needs to control the steering wheel for driving operation, the axial adjusting assembly 200 can be used to adjust the position of the steering wheel in the axial direction of the connecting shaft 1 to a suitable position; when the driver does not need to perform driving operation, the axial adjusting assembly 200 can be used to store the steering wheel in the instrument table of the vehicle, so as to reduce the occupation of the axial space.

[0042] It should be noted that the hand feeling simulation motor 10 refers to a motor for simulating the hand feeling of a steering wheel, which is usually used in an electric power steering system (EPS), and such a motor can make the driver feel a more realistic steering hand feeling during driving by simulating road feedback and steering resistance. The working principle of the hand feeling simulation motor 10 is known to those skilled in the art, and the present disclosure will not be repeated here.

[0043] According to the exemplary embodiments of the present disclosure, as shown in FIG. 1, Figures 1 to 4 By such an arrangement, when the hand feeling simulation motor 10 is integrated with the steering column assembly 100, the axial arrangement space between the first end 11 and the second end 12 can be used to arrange the hand feeling simulation motor 10, and thus, compared with arranging the hand feeling simulation motor 10 at the end of the steering column assembly 100, the above arrangement of the present disclosure can reduce the size of the steering column assembly 100 and the hand feeling simulation motor 10 in the axial direction of the connecting shaft 1, and thus, under the condition that the axial arrangement space is fixed, the above arrangement is beneficial to using the saved axial arrangement space to improve the adjustment stroke in the axial direction of the connecting shaft 1, which is beneficial to increasing the adjustable stroke of the steering wheel.

[0044] In the present disclosure, since the hand feeling simulation motor 10 is at least partially arranged between the first end 11 and the second end 12 of the connecting shaft 1, the hand feeling simulation motor 10 can be arranged at any position on the outer periphery of the connecting shaft 1 according to actual use requirements, which improves the flexibility of the arrangement of the hand feeling simulation motor 10.

[0045] It should be noted that the hand feeling simulation motor 10 refers to a motor for simulating the hand feeling of a steering wheel, which is usually used in an electric power steering system (EPS), and such a motor can make the driver feel a more realistic steering hand feeling during driving by simulating road feedback and steering resistance. The working principle of the hand feeling simulation motor 10 is known to those skilled in the art, and the present disclosure will not be repeated here.

[0046] It should be noted that when the axial adjustment stroke of the steering wheel is raised, the improvement of the user experience can mainly be reflected in the following aspects: first, when the steering wheel is adjusted axially downward, a larger axial adjustment stroke can provide a larger leg space for the driver, facilitating the driver to get in and out of the vehicle, second, the axial space is reduced, which can provide a larger resting space for the driver during the parking state of the vehicle, and in addition, when the main driver seat needs to be rotated or turned to the rear, a larger axial adjustment stroke can facilitate better storage of the steering wheel, release a larger arrangement space, and improve the space utilization.

[0047] According to another example embodiment of the present disclosure, the connecting shaft 1 has a first end 11 and a second end 12 arranged oppositely in the axial direction of the connecting shaft 1, and the feel simulation motor 10 includes a first output shaft 101 which can be connected to the second end 12, and the first axis of the first output shaft 101 is collinear with the second axis of the connecting shaft 1. In this way, the arrangement space of the steering column assembly 100 in the axial direction of the connecting shaft 1 can be more utilized to arrange the feel simulation motor 10, and the radial arrangement space of the feel simulation motor 10 on the connecting shaft 1 is reduced.

[0048] According to an example embodiment of the present disclosure, referring to Figure 4 , the steering wheel adjusting device includes a first transmission structure 4 for drivingly connecting the feel simulation motor 10 and the connecting shaft 1. The power output by the feel simulation motor 10 is transmitted to the connecting shaft 1 through the first transmission structure 4, which is conducive to the installation of the feel simulation motor 10 and reduces the limitations of the installation of the feel simulation motor 10.

[0049] According to an example embodiment of the present disclosure, referring to Figures 2 to 4 , the first output shaft 101 of the feel simulation motor 10 has a first axis, and the connecting shaft 1 has a second axis, and the first axis and the second axis can be perpendicular to each other. By arranging the first output shaft 101 of the feel simulation motor 10 to extend along the axial direction perpendicular to the connecting shaft 1, compared with arranging the first axis and the second axis parallel to each other, the arrangement space of the steering column assembly 100 in the radial direction of the connecting shaft 1 can be more utilized to arrange the feel simulation motor 10, and the axial arrangement space of the feel simulation motor 10 on the connecting shaft 1 is reduced, which is conducive to the compact design of the feel simulation motor 10 and the steering column assembly 100.

[0050] In the embodiment in which the first axis and the second axis are perpendicular to each other, referring to Figure 1 and Figure 4As shown in the figure, the first transmission structure 4 can include a transmission connected worm gear and worm 41, the worm 41 is coaxial and transmission connected with the first output shaft 101, and the worm gear is coaxial and transmission connected with the connecting shaft 1. By making the worm 41 coaxial and transmission connected with the first output shaft 101, the space occupation of the worm 41 in the axial direction of the connecting shaft 1 is reduced, which is beneficial to reduce the size of the steering wheel steering device provided by the present disclosure in the axial direction, wherein the first transmission structure 4 is arranged so that the hand feeling simulation motor 10 can be transmission connected with the connecting shaft 1 through the first transmission structure 4, which is convenient for the above-mentioned arrangement of the hand feeling simulation motor 10, that is, the first axis and the second axis can be perpendicular to each other. At this time, the first transmission structure 4 can also be arranged as a gear set, at this time, one gear in the gear set is coaxial and transmission connected with the first output shaft 101, and the other gear in the gear set is coaxial and transmission connected with the connecting shaft 1, so as to realize the transmission connection between the hand feeling simulation motor 10 and the connecting shaft 1.

[0051] According to another exemplary embodiment of the present disclosure, the first output shaft 101 of the hand feeling simulation motor 10 has a first axis, and the connecting shaft 1 has a second axis, and the first axis can be parallel to the second axis. In this way, the arrangement space of the steering column assembly 100 in the axial direction of the connecting shaft 1 can be more utilized to arrange the hand feeling simulation motor 10, and the radial arrangement space of the hand feeling simulation motor 10 to the connecting shaft 1 can be reduced.

[0052] In the embodiment in which the first axis can be parallel to the second axis, the first transmission structure 4 can include a first gear and a second gear in meshing engagement, the first gear is coaxial and transmission connected with the first output shaft 101, and the second gear is coaxial and transmission connected with the connecting shaft 1. By arranging in this way, the first output shaft 101 drives the first gear to rotate, the first gear drives the second gear to rotate, and the second gear drives the connecting shaft 1 to rotate, so as to realize the rotation of the steering wheel.

[0053] According to the exemplary embodiment of the present disclosure, with reference to Figures 1 to 4As shown in FIG. 1, the steering column assembly 100 can include a sleeve 5, the connecting shaft 1 is rotatably connected in the sleeve 5, and includes a slidingly connected first shaft body 13 and a second shaft body 14, the first shaft body 13 is in driving connection with the feel simulation motor 10, and the axial adjustment assembly 200 is in driving connection with the sleeve 5. In the above scheme, at least one of the first shaft body 13 and the second shaft body 14 is configured as a cylindrical structure, and the other is slidingly arranged in the cylindrical structure to achieve sliding connection of the first shaft body 13 and the second shaft body 14. The second shaft body 14 can be rotatably connected with the sleeve 5, for example, the second shaft body 14 can be rotatably connected with the sleeve 5 through a bearing. In this way, the connecting shaft 1 is in driving connection with the feel simulation motor 10 through the first shaft body 13, and the sleeve 5 can drive the second shaft body 14 to move along the axial direction of the first shaft body 13 under the action of the axial adjustment assembly 200, so as to adjust the position of the steering column assembly 100 in the axial direction of the connecting shaft 1, thereby realizing adjustment of the axial position of the steering wheel.

[0054] According to an exemplary embodiment of the present disclosure, referring to Figures 3 to 5 As shown in FIG. 1, the steering wheel adjusting device can include a housing 6, and a first adjusting structure 201 is used to make the steering column assembly 100 slide along the axial direction relative to the housing 6, so that the steering column assembly 100 has a first adjusting stroke. In the above technical scheme, the steering column assembly 100 is slidingly arranged in the housing 6.

[0055] According to an exemplary embodiment of the present disclosure, referring to Figures 3 to 5 As shown in FIG. 1, the first adjusting structure 201 includes a first drive motor 21, a first lead screw 22 and a first nut 23 in driving connection, the first drive motor 21 is mounted on the housing 6 and in driving connection with the first lead screw 22, the first nut 23 is connected with the steering column assembly 100, and the first lead screw 22 has a third end 221 and a fourth end 222 arranged oppositely in the axial direction of the first lead screw 22, and the first drive motor 21 is at least partially arranged between the third end 221 and the fourth end 222. By arranging the first adjusting structure 201, the position of the steering column assembly 100 in the axial direction of the connecting shaft 1 is adjusted. Specifically, when the first drive motor 21 works, the first lead screw 22 is driven to rotate, the first lead screw 22 drives the first nut 23 to move along the axial direction of the connecting shaft 1, and the first nut 23 drives the steering column assembly 100 to move along the axial direction of the connecting shaft 1.

[0056] In the present disclosure, by arranging the first driving motor 21 at least partially between the third end 221 and the fourth end 222, the axial arrangement space between the third end 221 and the fourth end 222 can be used to arrange the first driving motor 21, thereby, compared with arranging the first driving motor 21 at the end of the first lead screw 22, the above arrangement of the present disclosure can reduce the size of the primary adjustment structure 201 in the axial direction of the connecting shaft 1, so that in the case of a certain axial arrangement space, the above arrangement is beneficial to use the saved axial arrangement space to improve the adjustment stroke of the connecting shaft 1 in the axial direction, which is beneficial to increase the adjustable stroke of the steering wheel and improve the user experience.

When the first driving motor 21 works, the first nut 23 is driven to move along the avoiding gap 61 by the first lead screw, so as to drive the steering column assembly 100 to move and perform position adjustment.

[0059] In order to improve the protection performance, a collapse structure can be arranged between the steering column assembly 100 and the first nut 23, that is, the steering column assembly 100 is connected to the first nut 23 through the collapse structure. The collapse structure can be configured to be disconnected from the first nut 23 when the steering column assembly 100 is subjected to an impact force in the axial direction of the connecting shaft 1, so that the steering column assembly 100 collapses, that is, the steering column assembly 100 is retracted into the cavity of the shell 6, thereby reducing the harm caused by the steering wheel to the driver.

[0069] On the basis of the above technical solutions, the present disclosure further provides a vehicle comprising the above-mentioned steering wheel adjusting device. The vehicle provided by the present disclosure also has the above-mentioned characteristics. To avoid repetition, no further description is given here. In addition, since the steering wheel adjusting device provided by the present disclosure can adjust the steering wheel in two stages through the axial adjusting assembly 200, when the driver does not need to drive, the steering wheel can be stored in the instrument table of the vehicle by using the axial adjusting assembly 200, that is, the steering wheel can be folded and stored, thereby reducing the space occupation of the steering wheel in the axial direction of the connecting shaft 1.

[0070] Reference Figures 1 to 9 As shown in the figure, the use process of the embodiment of the present disclosure is described in detail as follows:

[0071] The steering wheel adjusting device provided by the present disclosure is installed on the vehicle. Specifically, the body seat 71 is fixed on the instrument table of the vehicle. When the axial position of the steering wheel needs to be adjusted, the second drive motor 25 can be started to move the shell 6 along the slide rail 72 (i.e., the axial direction of the connecting shaft 1). The movement of the shell 6 drives the steering column assembly 100 to move along the axial direction of the connecting shaft 1, thereby adjusting the position of the steering wheel in the axial direction of the connecting shaft 1. On this basis, the first drive motor 21 can also be started to drive the sleeve 5 to move the connecting shaft 1 relative to the shell 6 and along the axial direction of the connecting shaft 1. Thus, two-stage adjustment of the axial position of the steering wheel can be realized, and the adjustment stroke of the steering wheel in the axial direction of the connecting shaft 1 is increased. Of course, to improve the adjustment efficiency, the first drive motor 21 and the second drive motor 25 can be started at the same time to adjust the position of the steering column assembly 100 in the axial direction of the connecting shaft 1. The adjustment can be made according to the actual use requirements. Through testing, the highest speed of the single drive motor controlling the adjustment of the position of the steering wheel in the axial direction of the connecting shaft 1 is 25 mm / s to 35 mm / s. By using the above-mentioned manner provided by the present disclosure, the first drive motor 21 and the second drive motor 25 are started at the same time to adjust the position of the steering wheel in the axial direction of the connecting shaft 1, and the speed is 50~60mm / s, thereby improving the adjustment efficiency.

[0072] When the pitch angle of the steering wheel needs to be adjusted, the third driving motor 31 is started, the third driving motor 31 drives the third screw rod 34 to rotate, the third screw rod 34 drives the third nut 35 to move, the third nut 35 drives the swing arm 32 to rotate relative to the body seat 71, the swing arm 32 pushes or pulls the slide rail 72, so that the slide rail 72 rotates clockwise or counterclockwise around the hinge point where the first hinge shaft 73 is located, thereby adjusting the included angle between the slide rail 72 and the body seat 71, so as to realize the adjustment of the pitch angle of the steering wheel.

[0073] It should be noted that the stroke of the axial adjustment assembly 200 can be set according to different vehicle models. Since the primary adjustment structure 201 is closer to the side where the driver is located relative to the secondary adjustment structure 202, the stroke range of the primary adjustment structure 201 has greater limitations, and the overall stroke of the axial adjustment assembly 200 can be controlled by changing the stroke of the secondary adjustment structure 202.

[0074] In the related art, the hand feeling simulation motor 10 is arranged at the end of the steering column assembly 100, which results in that when the hand feeling simulation motor 10 is integrated with the steering column assembly 100, the overall size of the two in the axial direction of the steering column assembly 100 is large. In the present application, the hand feeling simulation motor 10 is arranged between the two ends of the steering column assembly 100, which can utilize the axial arrangement space between the first end 11 and the second end 12 to arrange the hand feeling simulation motor 10, thereby reducing the overall size of the steering column assembly 100 and the hand feeling simulation motor 10 in the axial direction of the connecting shaft 1. In this way, under the condition that the axial arrangement space is certain, the above-mentioned arrangement is beneficial to using the saved axial arrangement space to increase the adjustment stroke in the axial direction of the connecting shaft 1. Specifically, according to the adjustment stroke of 200 mm, the total length of the steering wheel adjustment device is 790 mm-810 mm when the hand feeling simulation motor 10 is arranged at the end of the steering column assembly 100, while the total length of the steering wheel adjustment device provided by the present application is 590 mm-610 mm for the same adjustment stroke. The arrangement space can be reduced by 180 mm-220 mm, which is beneficial to increasing the adjustment stroke of the steering wheel in the axial direction of the steering column and improving the user experience.

Various simple modifications can be made to the technical solutions of the present application within the technical concept of the present application, and these simple modifications all belong to the protection scope of the present application.

[0076] In addition, it should be noted that each specific technical feature described in the above specific embodiments can be combined in any appropriate manner without contradiction. In order to avoid unnecessary repetition, various possible combinations are not described again in the present application.

[0077] Furthermore, the various embodiments of the present disclosure can be arbitrarily combined with each other unless they contradict each other, and it should be understood that the same should be construed as being included in the disclosure of the present disclosure.
