Alternatively, the corresponding worm is directly operatively connected to the corresponding gear on the throttle shaft side, and the corresponding gear on the throttle shaft side is constructed as a worm wheel.

[0015] In some embodiments, a drive gear, a synchronizing gear set, and a driven gear on the drive side are provided. The drive gear on the drive side is operatively connected to the output component of the drive. The synchronizing gear set is disposed between the drive gear and the driven gear on the drive side and meshes with the drive gear and the driven gear on the drive side respectively. The drive gear and the driven gear on the drive side are rotated in the same direction by the synchronizing gear set.

[0016] In some embodiments, a driving worm and a driven worm are provided, wherein the driving worm is connected to the driving gear on the driver side in a non-rotatable manner, and the driven worm is connected to the driven gear on the driver side in a non-rotatable manner.

[0043] Firstly, by using Figures 1 to 2C The basic construction of a concealed steering wheel assembly 1 according to some embodiments of the present disclosure is described.

[0044] like Figure 1 As shown, the concealed steering wheel assembly 1 according to this disclosure includes a steering wheel body 12, a steering wheel rim 11 pivotable relative to the steering wheel body 12, and steering wheel spokes 13, wherein the steering wheel rim 11 can pivot about a pivot axis Z offset from the center of the steering wheel body 12.

[0045] Reference Figures 2A to 2B The concealed steering wheel assembly 1 also includes a retractable steering column 3. The steering wheel body 12 is mounted on the steering column 3, for example, by means of a spline 4. The steering column 3 is configured to extend and retract between a retracted state and an extended state. Figure 2A and Figure 2B As shown, the steering column 3 includes a column motor 31, a column screw 32, and a column guide sleeve 33. The column guide sleeve 33 is operatively connected to the column screw 32. The column screw 32 is operatively connected to the column motor 31. The column guide sleeve 33 is fixedly mounted on the steering column 3. The column motor 31 drives the column screw 32 to rotate, which in turn drives the column guide sleeve 33, along with the steering column 3, to extend and retract, thereby causing the steering wheel body 12, along with the steering wheel rim 11, to extend and retract. Furthermore, referring to… Figure 2C In order to guide the extension and retraction of the steering column 3, a column guide rail 34 is also provided, and the steering column 3 extends and retracts under the guidance of the column guide rail 34.

[0046] Then, with the help of Figures 3A to 6B The operation of a concealed steering wheel assembly 1 according to some embodiments of the present disclosure is described.

[0047] Figures 3A to 6BThe steering wheel rim 11 of the concealed steering wheel assembly 1 shown is an interrupted rim, which has a unique folding and concealing method. (Refer to...) Figure 3A and Figure 3B In the steering wheel operating state, the steering wheel rim 11 is in the operating position, while the steering wheel column 3 extends outward relative to the instrument panel 2 and is in the column extended position. This is to bring the concealed steering wheel assembly 1 from the steering wheel operating state to... Figure 6A and Figure 6B The steering wheel is shown in its hidden folded state. Firstly, it can be... Figure 4A and Figure 4B The steering column 3 extends outward, i.e., toward the driver (as shown by the arrow), to provide clearance for the pivoting of the steering wheel rim 11 relative to the instrument panel 2, or to allow for folding space for the steering wheel rim 11. Then it can be done as follows... Figure 5A and Figure 5B As shown, pivot the steering wheel throttle 11 backwards, that is, pivot around the pivot axis Z towards the head of the vehicle (as indicated by the arrow). Finally, it can be done as follows... Figure 6A and Figure 6B As shown, with the steering wheel rim 11 pivoted in the folded position, the steering column 3 is retracted towards the front of the vehicle (as indicated by the arrow) until the steering wheel body 12 is housed within the vehicle's dashboard 2. This provides more space for occupants to engage in non-driving activities. Figure 3B and Figure 6B It can also be clearly seen that the dashboard 2 includes a first receiving portion 21 for accommodating the steering wheel body 12 of the concealed steering wheel assembly 1. The shape of the first receiving portion 21 matches the shape of the steering wheel body 12. This allows for advantageous accommodation of the steering wheel body 12 within the dashboard 2. Furthermore, the dashboard 2 also includes a second receiving portion 22 for accommodating the steering wheel rim 11 of the concealed steering wheel assembly 1. The shape of the second receiving portion 22 matches the shape of the folded steering wheel rim 11. This allows for advantageous accommodation, or storage, of the steering wheel rim 11 within the dashboard 2. Additionally, especially from... Figure 6B It can also be seen that the surface contours of the driver-facing surface of the steering wheel body 12 and the driver-facing surface of the instrument panel 2 are constructed such that, in the folded and hidden state of the steering wheel, the surface contour of the steering wheel body 12 is flush with the surrounding surface contour of the instrument panel 2. Thus, in the folded and hidden state of the steering wheel, the steering wheel body 12 can be integrated with the instrument panel 2, achieving seamless storage of the steering wheel body 12 within the instrument panel 2. Furthermore, as shown in the figure, the steering wheel rim 11, the steering wheel body 12, and the pivot axis Z are designed such that, after the steering wheel rim 11 is pivoted to the folded state, the outermost edge of the steering wheel rim 11 is flush with the outermost edge of the steering wheel body 12.

[0048] In addition to the interrupted handlebars described above, in other embodiments, such as... Figure 7 As shown, the steering wheel rim 11 of the concealed steering wheel assembly 1 can also be constructed as a non-interrupted rim. Here, in order to conceal the steering wheel assembly 1 from... Figure 7 The steering wheel, in its working state, can be brought to its concealed folded state by pivoting the steering wheel rim 11 forward, i.e., towards the driver. After switching to the folded rim state, the steering wheel rim 11 can be moved inward parallel to the longitudinal direction of the steering wheel body 12 so that the outermost edge of the steering wheel rim 11 (the driver-facing side) is substantially flush with the outermost edge of the steering wheel body 12 (the driver-facing side). Finally, the steering column 3 can be retracted towards the head of the vehicle until the steering wheel body 12 is accommodated in the vehicle's dashboard 2.

[0049] from Figures 8A to 8D As can be seen, the steering wheel rim 11 and steering wheel spokes 13 can be connected to the steering wheel body 12 via connecting lugs 132 on the steering wheel spokes 13; and can also be connected to the base 122 of the steering wheel body 12 via multiple other connection points 133 on the steering wheel spokes 13, for example, connected to corresponding connection points 1221 on the base 122. Furthermore, a rim rotation mechanism 131 is provided, which is at least partially disposed within the steering wheel spokes 13, particularly the spoke housing 134, and allows for the pivoting of the steering wheel rim 11. (Refer to...) Figure 9A and Figure 9B The steering wheel rotation mechanism 131 may include a steering wheel shaft 1311, which is fixedly connected to the steering wheel rim 11. For example... Figure 9B As shown, the steering wheel rim 11 may include, for example, a rim frame 111 made of metal and a rim outer ring 112, and the rim pivot 1311 may be fixed to the rim frame 111 by a rim pivot bolt 1311a.

[0050] The following uses Figures 10 to 12 The structure of the steering wheel rim rotation mechanism 131 used to realize the pivoting of the steering wheel rim 11 is described.

[0051] In some embodiments, the wheel swivel mechanism 131 includes a driver 1312 capable of outputting rotational motion and a transmission mechanism. The transmission mechanism includes a driver-side gear operatively connected to the output element of the driver 1312, a worm gear non-rotatably connected to the driver-side gear, and a wheel swivel-side gear 1319. The wheel swivel-side gear 1319 is fixed to the wheel swivel shaft 1311, and the worm gear is directly or indirectly operatively connected to the wheel swivel-side gear 1319. (Refer to...) Figure 11The driver 1312 can be configured as a drive motor capable of outputting rotary motion, and the output component of the driver 1312 can be configured as a motor connector 1312a. For achieving transmission, refer to... Figure 11 In some embodiments, the transmission mechanism may include a drive gear 1314a on the driver side, a synchronizing gear set, and a driven gear 1314b on the driver side. The synchronizing gear set is disposed between the drive gear 1314a and the driven gear 1314b on the driver side and meshes with both gears respectively. The drive gear 1314a on the driver side can be operatively connected to a motor connector 1312a. Rotation of the motor connector 1312a can drive the drive gear 1314a on the driver side to rotate together. The rotation of the drive gear 1314a on the driver side can, in turn, cause the driven gear 1314b on the driver side to rotate in the same direction as the drive gear 1314a through the synchronizing gear 1316 in the synchronizing gear set. See also... Figure 12 For example, the counterclockwise rotation of the driving gear 1314a on the driver side can cause the driven gear 1314b on the driver side to rotate counterclockwise as well via the synchronizing gear 1316. Regarding the number of synchronizing gears 1316, besides... Figure 11 and Figure 12 In addition to the single synchronizing gear 1316 shown, it is also conceivable to provide other odd numbers of synchronizing gears 1316. These odd numbers of synchronizing gears ensure that the driving gear 1314a and the driven gear 1314b on the driver side always rotate in the same direction. The driving gear 1314a, the synchronizing gear set, and the driven gear 1314b on the driver side can be arranged in a gearbox, which may include a gearbox body 1313b and a gearbox cover 1313a.

[0052] In addition to the gear sets mentioned above, refer to Figure 11 The transmission mechanism also includes a driving worm 1317a and a driven worm 1317b. The driving worm 1317a is non-rotatably connected to the driving gear 1314a on the driver side, and the driven worm 1317b is non-rotatably connected to the driven gear 1314b on the driver side. That is, rotation of the driving gear 1314a on the driver side can drive the driving worm 1317a to rotate at the same speed and in the same direction, and rotation of the driven gear 1314b on the driver side can also drive the driven worm 1317b to rotate at the same speed and in the same direction. Figure 11As shown, a drive shaft 1315a and a driven shaft 1315b are fixedly connected to the drive gear 1314a and the driven gear 1314b on the drive side, respectively. A worm gear 1317a on the drive side and a worm gear 1317b on the driven side are also fixedly connected to the drive shaft 1315a and the driven shaft 1315b, respectively, thus achieving a connection where they cannot rotate relative to each other. Figure 10 and Figure 11 It can be seen that the driving worm 1317a and the driven worm 1317b can be respectively accommodated in the worm receiving portion 1313c extending from the end face of the gearbox body 1313b.

[0053] The aforementioned driving gear 1314a on the driver side, driven gear 1314b on the driver side, and driving worm 1317a and driven worm 1317b can achieve very smooth motion transmission.

[0054] In order to transmit the motion of the driving worm 1317a and the driven worm 1317b to the rim shaft 1311, as follows Figure 10 and Figure 11 In the illustrated embodiment, intermediate gear sets are also provided between the gear 1319 on the corresponding steering wheel shaft side of the steering wheel shaft 1311 and the corresponding driving worm 1317a and driven worm 1317b. For ease of explanation, only one intermediate gear set will be described below. This intermediate gear set may include an intermediate synchronizing gear 1318a and an intermediate worm gear 1318b. The intermediate synchronizing gear 1318a cannot rotate relative to the intermediate worm gear 1318b. Therefore, the intermediate synchronizing gear 1318a and the intermediate worm gear 1318b can be connected to the same gear pin 1318c. The gear pin 1318c can be provided in a mounting hole at the protrusion 1313d extending from the worm receiving portion 1313c. The intermediate worm gear 1318b can be operatively connected to the corresponding worm, while the intermediate synchronizing gear 1318a can be operatively connected to the gear 1319 on the corresponding steering wheel shaft side. This allows for an indirect transmission connection between the worm gear and the gear 1319 on the corresponding crankshaft side. For example... Figure 10 As shown, taking the active worm gear 1317a as an example, the clockwise rotation of the active worm gear 1317a can drive the gear 1319 on the rim shaft side to rotate via the intermediate synchronizing gear 1318a and the intermediate worm wheel 1318b, thereby driving the rim shaft 1311 to rotate around the pivot axis Z. Figure 10 Rotate in the direction shown.

[0055] In addition to the indirect transmission connection described above, in other embodiments, such as Figure 13As shown, the corresponding driving worm 1317a and driven worm 1317b can also be directly connected to the gear 1319 on the corresponding throttle shaft side. Here, the gear 1319 on the corresponding throttle shaft side is constructed as a worm gear. Figure 13 In the embodiment shown, taking the driving worm 1317a as an example, since the intermediate gear set is eliminated, the counterclockwise rotation of the driving worm 1317a can cause the rotating shaft 1311 to rotate around the pivot axis Z along the axis of rotation. Figure 10 Rotate in the same direction as shown in the diagram.

[0056] Not limited to the embodiments described in conjunction with the accompanying drawings, it is also possible for the steering wheel rim 11 to be constructed in a split manner, and for example, to be provided with multiple (sub)rims, such as an upper rim and a lower rim. The upper rim and the lower rim can, for example, pivot rearward separately, thus also realizing a folding rim structure that can be accommodated in the instrument panel 2.
