[0037] To make the purpose, technical solutions, and advantages of the embodiments of this application more clear, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0038] An embodiment of the present application provides an adjustable steering wheel assembly, which can solve the problem in the related art that the steering wheel cannot achieve independent tilt rotation adjustment relative to the steering column.

[0039] See also Figures 1 to 10 As shown, an embodiment of the present application provides an adjustable steering wheel assembly, which includes a steering wheel body 1, a base 2 and a limit portion, wherein the steering wheel body 1 is movably connected to the base 2. Specifically, a first adjustment portion is provided on the steering wheel body 1, and a second adjustment portion is provided on the base 2. One end of the base 2 is rotatably connected to the steering wheel body 1 and the first adjustment portion through the second adjustment portion, and the other end is connected to the steering column 3. The relative rotation between the steering wheel body 1 and the base 2 is realized.

[0040] Furthermore, the limiting portion is provided between the first adjusting portion and the second adjusting portion, for limiting the relative rotation of the first adjusting portion and the second adjusting portion. Figure 1 and Figure 2 As shown, a mounting hole 21 is provided on the base 2 , and the steering column 3 is fixed to the base 2 through the mounting hole 21 .

[0041] The present invention provides an adjustable steering wheel assembly and a vehicle. A base 2 is provided between a steering wheel body 1 and a steering column 3. The base 2 serves as an intermediate transition portion. A first adjustment portion and a second adjustment portion are provided on the steering wheel body 1 and the base 2, respectively, so that the steering wheel body 1 can be rotatably connected to the base 2, thereby achieving relative movement between the steering wheel body 1 and the base 2, and further achieving relative movement between the steering wheel body 1 and the steering column 3.

[0042] A limit portion is further provided to limit the relative rotation of the first adjustment portion and the second adjustment portion, thereby limiting the adjustment amount of the steering wheel body 1 and avoiding interference between the steering wheel body 1 and surrounding objects. Therefore, the problem in related technologies that the steering wheel cannot achieve independent tilt rotation adjustment relative to the steering column can be solved.

[0043] In some optional embodiments, see Figures 1 to 6 As shown, the first adjustment part includes a first adjustment toothed disc 4, and the second adjustment part includes a second adjustment toothed disc 5, wherein Figure 1 As shown, the second adjusting toothed disc 5 is coaxial with the first adjusting toothed disc 4 and meshes with it. Figure 6 As shown, the end of the second adjusting toothed disc 5 away from the first adjusting toothed disc 4 is provided with an inner concave sink 53, and the first adjusting toothed disc 4 and the second adjusting toothed disc 5 are fixed by a screw 6, and a compression spring 7 and a fixing member are sleeved on the screw 6, and the compression spring 7 is limited in the inner concave sink 53 by the fixing member;

[0044] Furthermore, the limiting portion includes a limiting groove 52 and a limiting boss 42, and the limiting groove 52 and the limiting boss 42 are selectively arranged on the first adjustment gear plate 4 and the second adjustment gear plate 5, and the limiting boss 42 is clamped in the limiting groove 52, and the length of the limiting boss 42 is less than the length of the limiting groove 52.

[0045] The relative rotation of the second adjusting toothed disc 5 and the first adjusting toothed disc 4 enables the inclination angle of the steering wheel body 1 relative to the steering column 3 to be adjusted. The compression spring 7 is sleeved on the screw 6 connecting the second adjusting toothed disc 5 and the first adjusting toothed disc 4, and applies a compression force to the second adjusting toothed disc 5 and the first adjusting toothed disc 4, so that the second adjusting toothed disc 5 and the first adjusting toothed disc 4 fit firmly. The limiting boss 42 slides in the limiting groove 52, thereby limiting the steering wheel body from interfering with the instrument panel cover and other plastic parts.

[0046] Optionally, combined Figure 2 As shown, the fixing part includes a gasket 61 and a nut 62. The diameter of the gasket 61 should be larger than the inner diameter of the inner concave sink 53 to limit the compression spring 7 in the inner concave sink 53. Then, by passing the nut 62 on the screw 6, it is pressed on the end of the gasket 61 away from the inner concave sink 53 to limit the compression spring 7 in the inner concave sink 53.

[0047] In some optional embodiments, see Figures 3 to 6 As shown, the opposite sides of the first adjusting tooth disc 4 and the second adjusting tooth disc 5 are respectively provided with end face teeth 41 and end face tooth grooves 51. The end face teeth 41 are arranged along the radial direction of the first adjusting tooth disc 4, and there are multiple end face teeth 41. The multiple end face teeth 41 are arranged at intervals along the circumference of the first adjusting tooth disc 4, and the end face tooth grooves 51 are arranged corresponding to the end face teeth 41.

[0048] Since the end face tooth groove 51 is arranged opposite to the end face tooth 41 and meshes with each other, the second adjustment tooth plate 5 and the first adjustment tooth plate 4 are connected in series through the screw 6, and the clamping force of the compression spring 7 causes the end face tooth 41 to be limited in the end face tooth groove 51, the tooth and the groove cooperate firmly, and the limiting boss 42 slides in the limiting groove 52, thereby limiting the steering wheel body 1 from interfering with the instrument surface cover and other plastic parts.

[0049] When driving normally, the steering wheel body 1 is fixed to the base 2 through the first adjusting toothed disc 4 and the second adjusting toothed disc 5, and the compression spring 7, so that the steering wheel body 1 and the base 2 will not rotate relative to each other. Since the first adjusting toothed disc 4 and the second adjusting toothed disc 5 are coaxially arranged and connected by the screw 6 and the compression spring 7 is limited, combined with Figure 1 As shown, the first adjusting toothed disc 4 is parallel to the second adjusting toothed disc 5. The end face teeth 41 of the first adjusting toothed disc 4 engage with the end face tooth grooves 51 of the second adjusting toothed disc 5, and the driver can rotate the steering wheel body 1 normally.

[0050] When the steering wheel body 1 needs to be adjusted, the steering wheel body 1 can adjust the tilt angle by relatively rotating the first adjusting gear plate 4 and the second adjusting gear plate 5 on the base 2 . Specifically, the first adjusting tooth disc 4 and the second adjusting tooth disc 5 are coaxially installed. Before rotation, the end face teeth 41 of the first adjusting tooth disc 4 and the second adjusting tooth disc 5 are engaged with the end face tooth groove 51, and a force is applied along the penetration direction of the screw 6 to move the first adjusting tooth disc 4 and the second adjusting tooth disc 5 away from each other. At this time, the first adjusting tooth disc 4 and the second adjusting tooth disc 5 overcome the pressing force of the compression spring 7, and the end face teeth 41 currently engaged are disengaged from the end face tooth groove 51 and enter the next end face tooth groove 51 of the second adjusting tooth disc 5. At this time, if the external force is stopped, the end face teeth 41 and the end face tooth groove 51 are engaged again. If the external force is continuously applied, the first adjusting tooth disc 4 continues to rotate relative to the second adjusting tooth disc 5. When the expected position is reached, the external force is stopped, and the end face teeth 41 of the first adjusting tooth disc 4 finally fall back into the end face tooth groove 51 of the second adjusting tooth disc 5.

[0051] Furthermore, when the first adjusting toothed disc 4 and the second adjusting toothed disc 5 are adjusted to engage with each other, the limiting boss 42 slides in the limiting groove 52 to avoid excessive adjustment and interference with surrounding objects or obstacles.

[0052] Optionally, combined Figure 3 As shown, the width of the end teeth 41 decreases from the end with the larger radius of the first adjustment toothed disc 4 to the end with the smaller radius of the first adjustment toothed disc 4. The end surface of the first adjustment toothed disc 4 is circular, and the end teeth 41 are evenly distributed on the first adjustment toothed disc 4. Since the inner diameter of the first adjustment toothed disc 4 gradually decreases from the edge to the center radius, the width of the end teeth 41 should gradually decrease from the outside to the inside (from the larger radius end to the smaller radius end).

[0053] Preferably, the limiting boss 42 and the end face teeth 41 are both provided on the first adjusting toothed disc 4, that is, the raised portions are both located on the same adjusting toothed disc, and correspondingly, the limiting groove 52 and the end face teeth 51 are also provided on the same adjusting toothed disc, that is, Figures 3 to 6 shown.

[0054] Furthermore, the limiting boss 42 is provided on the first adjusting gear disc 4 , and the limiting boss 42 is arc-shaped and is coaxially provided with the first adjusting gear disc 4 .

[0055] Regarding the arrangement of the end face teeth 41 and the limiting boss 42, this application provides the following two embodiments:

[0056] Example 1:

[0057] See also Figure 3 As shown, the end face tooth 41 is arranged on one of the end faces of the first adjusting tooth disc 4, its length direction is parallel to the radial direction of the first adjusting tooth disc 4, and its distribution pattern is arranged along the circumference of the first adjusting tooth disc 4. The limiting boss 42 is arranged to avoid the end face tooth 41 and is located at the end face tooth 41 near the axis of the first adjusting tooth disc 4.

[0058] Specifically, the limiting boss 42 is arc-shaped and is coaxially arranged with the first adjusting toothed disc 4, that is, Figure 3 As shown, the arc-shaped limiting boss 42 coaxial with the first adjusting toothed disc 4 can make the first adjusting toothed disc 4 and the second adjusting toothed disc 5 rotate coaxially without obstruction. Figure 5 As shown, the limiting groove 52 provided on the second adjusting toothed disc 5 is also arc-shaped and is coaxially arranged with the second adjusting toothed disc 5 .

[0059] Preferably, in order to limit the relative rotation angle between the first adjusting toothed disc 4 and the second adjusting toothed disc 5 and to make the relative rotation angle between the steering wheel body 1 and the base 2 larger, the limiting groove 52 is as follows: Figure 5 The major arc shown is an arc that is larger than a semicircle; when the limiting boss 42 slides in the limiting groove 52, it stops sliding due to the length limitation of the limiting groove 52, thereby achieving the purpose of limiting.

[0060] And, preferably, the height of the limiting boss 42 protruding from the first adjusting tooth disc 4 should be greater than the height of the end face teeth 41. When the end face teeth 41 are subjected to a force that causes the first adjusting tooth disc 4 and the second adjusting tooth disc 5 to move away from each other, the first adjusting tooth disc 4 and the second adjusting tooth disc 5 overcome the clamping force of the clamping spring 7. The currently engaged end face teeth 41 disengage from the end face tooth groove 51, and the limiting boss 42 will not disengage from the limiting groove 52, thereby limiting the relative rotation angle of the first adjusting tooth disc 4 and the second adjusting tooth disc 5.

[0061] Optionally, the opening range of the limiting groove 52 can be three-quarters of a circle or four-fifths of a circle, which can be specifically set according to different cab spaces.

[0062] Example 2:

[0063] The difference from the first embodiment is that the limiting boss 42 is not as Figure 3 The arrangement shown avoids the face gear 41 and is instead arranged to partially overlap with the face gear 41 .

[0064] The width of the limiting boss 42 is smaller than the length of the end face teeth 41 . Even if the setting position of the limiting boss 42 coincides with the setting position of the end face teeth 41 , it does not affect the engagement of the end face teeth 41 in the end face tooth grooves 51 .

[0065] Furthermore, a limiting groove 52 is provided on the second adjusting toothed disc 5 . The limiting groove 52 is arc-shaped and is coaxially arranged with the second adjusting toothed disc 5 . The width of the limiting groove 52 is smaller than the length of the end face tooth groove 51 .

[0066] Preferably, the height of the limiting boss 42 protruding from the first adjusting tooth disc 4 should be greater than the height of the end face teeth 41. When the end face teeth 41 are subjected to a force that causes the first adjusting tooth disc 4 and the second adjusting tooth disc 5 to move away from each other, the first adjusting tooth disc 4 and the second adjusting tooth disc 5 overcome the clamping force of the clamping spring 7. The currently engaged end face teeth 41 disengage from the end face tooth groove 51, and the limiting boss 42 will not disengage from the limiting groove 52, thereby limiting the relative rotation angle of the first adjusting tooth disc 4 and the second adjusting tooth disc 5.

[0067] For an adjustable steering wheel assembly, this application provides the following two embodiments:

[0068] Example 1:

[0069] That is Figures 1 to 6 As shown, this embodiment provides the first adjustment toothed disc 4 and the second adjustment toothed disc 5 as described above, wherein the combination Figure 1 and Figure 2As shown, the first adjusting toothed disc 4 is connected to the steering wheel body 1 through the first adjusting toothed disc bracket 43, and the second adjusting toothed disc 5 is connected to the base 2 through the second adjusting toothed disc bracket 54. Specifically, there are two first adjusting toothed discs 4 and two second adjusting toothed discs 5, and the first adjusting toothed discs 4 and the second adjusting toothed discs 5 are combined in pairs, and the end face teeth 41 are engaged with the end face tooth grooves 51; when a force in the length direction of the screw 6 is applied to the first adjusting toothed disc 4 and the second adjusting toothed disc 5, the two groups of connected first adjusting toothed discs 4 and second adjusting toothed discs 5 move in the direction of moving away from or approaching each other.

[0070] Optionally, the first adjustment sprocket 4 and the second adjustment sprocket 5 can be moved away from or closer to each other by applying force to the steering wheel body 1. Optionally, a fixing frame 431 is connected between the steering wheel body 1 and the first adjustment sprocket bracket 43 to provide support for the steering wheel body 1 and the first adjustment sprocket 4.

[0071] Combine Figure 7 As shown, Figure 7 When the first adjusting sprocket 4 and the second adjusting sprocket 5 are rotationally adjusted, the angle between the steering wheel body 1 and the steering column 3 changes.

[0072] Example 2:

[0073] See also Figure 8 and Figure 9 As shown, this embodiment provides the first adjusting toothed disc 4 and the second adjusting toothed disc 5 as described above, wherein the first adjusting toothed disc 4 and the second adjusting toothed disc 5 each have one, as shown in FIG. Figure 8 As shown, the first adjusting gear disc 4 is connected to the steering wheel body 1 through a first adjusting gear disc bracket 43 , and the second adjusting gear disc 5 is connected to the base 2 through a second adjusting gear disc bracket 54 .

[0074] Furthermore, a driving unit 8 is provided between the steering wheel body 1 and the base 2. The driving unit 8 includes a motor 81 and a gear part. The motor 81 is used to drive the gear part to rotate and make the steering wheel body 1 and the base 2 rotate relative to each other, and the rotation axis of the gear part is consistent with the rotation axis of the first adjustment gear plate 4; that is, relative to Example 1, this embodiment replaces one of the two groups of first adjustment gear plates 4 and second adjustment gear plates 5 with the driving unit 8.

[0075] Specifically, combined Figure 8 and Figure 9 As shown, the motor 81 is fixed on the base 2;

[0076] The gear assembly includes a gear 82 connected to the motor 81 and a third adjustment gear plate 83. The third adjustment gear plate 83 is disposed on the steering wheel body 1 and engages with the gear 82. Furthermore, the motor 81 is fixed to the base 2 via a motor bracket 84, and the third adjustment gear plate 83 is connected to the steering wheel body 1 via a third adjustment gear plate bracket 85.

[0077] See also Figure 9 As shown, a gear 82 is mounted on one end of the motor 81, which drives the gear 82 to rotate. The third adjustment toothed disc 83 includes internal teeth on a countersunk platform and is provided with a through hole. A motor shaft extends from the motor 81 and passes through the through hole. The third adjustment toothed disc 83 is fixed to the motor 81 by fixing bolts. When the third adjustment toothed disc 83 and the motor 81 are installed, the third adjustment toothed disc 83 engages with the gear 82 on the motor 81.

[0078] Furthermore, a power switch 86 is provided on the steering wheel body 1, and the power switch 86 is electrically connected to the motor 81. When in use, the power switch 86 is pressed, and the motor 81 drives the gear 82 on its motor shaft to rotate. Since the third adjustment gear plate 83 and the gear 82 are engaged with each other through the internal teeth, the third adjustment gear plate 83 is driven to rotate, and further drives the steering wheel body 1 connected thereto to move. During the rotation of the motor 81, the first adjustment gear plate 4 and the second adjustment gear plate 5 are used to apply force in the length direction of the screw 6, compressing the compression spring 7, so that the first adjustment gear plate 4 and the second adjustment gear plate 5 overcome the compression force of the compression spring 7, and the end face teeth 41 currently engaged are disengaged from the end face tooth groove 51 and enter the next end face tooth groove 51 of the second adjustment gear plate 5. At the same time, the limit part limits the rotation. When the limit part generates a limit, the motor 81 is blocked and the power switch 86 is turned off, i.e., the motor reaches the final position.

[0079] Compared with the first embodiment, this embodiment replaces one set of the first adjustment gear plate 4 and the second adjustment gear plate 5 with a driving unit 8, which is driven by a motor, making the operation and adjustment more labor-saving.

[0080] In some optional embodiments, see Figure 7 and Figure 10 As shown, when the steering wheel body 1 is adjusted to be parallel to the XY plane of the vehicle coordinate system, a storage plate 9 can be added to the steering wheel body 1. Specifically, the storage plate 9 is as shown in FIG. Figure 10 The stowage plate 9 is detachably mounted on the end of the steering wheel body 1 away from the base 2 via the stowage plate 91, thereby providing the driver with a level stowage platform and improving the convenience of use.

[0081] The embodiments of the present application provide an adjustable steering wheel assembly, which has the following advantages:

[0082] (1) The adjustable steering wheel assembly provided in the embodiment of the present application, through the combined use of the first adjustment toothed disc 4 and the second adjustment toothed disc 5, and the driving portion 8, can achieve the purpose of relative rotational fixation between the steering wheel body 1 and the base 2 by the cooperation of the end face teeth 41 and the end face tooth grooves 51 and the compression of the compression spring 7;

[0083] (2) The adjustable steering wheel assembly provided in the embodiment of the present application has a limit portion provided between the first adjustment toothed disc 4 and the second adjustment toothed disc 5, which can limit the relative rotation angle between the two. By controlling the opening range of the limit groove 52 and the setting length of the limit boss, the purpose of not interfering with the instrument cover and other plastic parts is achieved;

[0084] (3) The adjustable steering wheel assembly provided in the embodiment of the present application can adjust the tilt angle of the steering wheel body 1 to a horizontal position while satisfying the structure of the steering wheel body 1, thereby providing the driver with a horizontal storage platform and improving the convenience of use;

[0085] (4) In the adjustable steering wheel assembly provided in the embodiment of the present application, since the distance between the steering wheel body 1 and the rotation axis (the rotation axis of the first adjustment gear plate 4 and the second adjustment gear plate 5) is reduced, the turning radius is reduced, and thus the rotation angle is increased, thereby improving the rotation range of the steering wheel body 1 relative to the steering column 3;

[0086] (5) The adjustable steering wheel assembly provided in the embodiment of the present application has rotating parts concentrated above the steering column 3 rather than inside the steering column 3. Therefore, there is no need to leave a gap between the steering column 3 and the steering column shield. The steering column shield can fit the steering column 3 more closely, thereby increasing the space for human movement.

[0087] An embodiment of the present application also provides a vehicle, which includes an adjustable steering wheel assembly as described above.
