DETAILED DESCRIPTION

[0020] In order to make the purpose, technical solutions and advantages of the present disclosure clearer, the following will further describe the embodiments of the present disclosure in combination with the drawings.

[0021] It should be noted that the embodiments in the present disclosure and the features in the embodiments can be combined with each other without conflict. The present disclosure will be described in detail below with reference to the drawings and in combination with the embodiments.

[0022] The present disclosure provides a steering wheel assembly. As shown in Figure 1 , Figure 2 The steering wheel assembly includes a steering wheel body 1, a steering column 2, a folding drive mechanism 3 and a telescopic drive mechanism. The steering wheel body 1 includes a base 11, a display screen 12 and a handlebar assembly 13, the base 11 is connected with the steering column 2, the display screen 12 is fixed to the side of the base 11 away from the steering column 2, and the handlebar assembly 13 is rotationally connected with the base 11. As shown in Figure 1 The handlebar assembly 13 has a folding position inside the edge of the base 11, as shown in Figure 3 The handlebar assembly 13 has an unfolded position protruding from the edge of the base 11. The folding drive mechanism 3 is connected with the handlebar assembly 13 to drive the rotation of the drive assembly 31. The telescopic drive mechanism is connected with the base 11 to drive the axial movement of the base 11 towards the steering column 2.

[0023] Using the steering wheel assembly provided in this embodiment, during autonomous driving, the grip assembly 13 can be moved to the folding position by the folding drive mechanism 3, and the base 11 can be retracted into the vehicle body by the telescopic drive mechanism. In this process, only enough space needs to be reserved in the direction of the vertical steering column 2 to retract the base 11, thereby reducing the space occupied by the steering wheel in the direction of the vertical steering column 2.

[0024] The display screen 12 can be an in-vehicle display screen 12, which can be used to display audio and video entertainment images to provide entertainment services to users when the vehicle is in autonomous driving mode. Of course, the display screen 12 can also be used to display navigation information to provide navigation services to users when the vehicle is in manual driving mode. Of course, the display screen 12 can also have other functions, and this embodiment does not limit them.

[0025] Optionally, the telescopic drive mechanism can be, for example, but not limited to, a worm gear mechanism. Of course, other mechanisms are also possible, and this disclosure does not limit the embodiments thereto.

[0026] like Figure 2 As shown, in some embodiments, the grip assembly 13 includes a first grip 131 and a second grip 132, the first grip 131 and the second grip 132 are arranged symmetrically, and when the grip assembly 13 rotates, the first grip 131 and the second grip 132 rotate in opposite directions.

[0027] Thus, the first grip 131 and the second grip 132 are separate structures. When the first grip 131 and the second grip 132 rotate, the first grip 131 and the second grip 132 can synchronously retract inward or expand outward. The reverse rotation design allows the movement trajectories of the two grips to perfectly "avoid" each other and move to the designated position in the most efficient path, thereby making it more convenient to retract the first grip 131 and the second grip 132 to the back of the base 11.

[0028] Furthermore, since the movements of the two grips are synchronous and mirror-symmetrical, they can be driven together by the same folding drive mechanism 3. This is simpler in structure, lower in cost, more synchronous in control, and more reliable than using two separate drivers to control the two grips separately.

[0029] like Figure 2 As shown, the base 11 includes a base plate 111, a first hinge seat 171, and a second hinge seat 172. The first hinge seat 171 and the second hinge seat 172 are fixedly connected to the base plate 111. The end of the first grip 131 is hinged to the first hinge seat 171, and the end of the second grip 132 is hinged to the second hinge seat 172. This allows the first grip 131 and the second grip 132 to rotate relative to the base 11.

[0030] Optionally, the first hinge seat 171 and the second hinge seat 172 are respectively hinged to the base 11 by screws.

[0031] like Figure 2 As shown, the first grip 131 and the second grip 132 are L-shaped to facilitate gripping by the user.

[0032] Optionally, the steering column 2 can be a steer-by-wire column 2, thereby reducing the actual rotation range of the steering wheel during use.

[0033] Combination Figure 4 , Figure 5 As shown, in some embodiments, the folding drive mechanism 3 includes a drive assembly 31, a first transmission assembly 32, and a second transmission assembly 33. The first transmission assembly 32 includes a first worm 321 and a first worm wheel 322. The first worm 321 is rotatably connected to the base 11 and is driveably connected to both the drive assembly 31 and the first worm wheel 322. The first worm wheel 322 is connected to the first handle 131. The second transmission assembly 33 includes a second worm 331 and a second worm wheel 332. The second worm 331 is rotatably connected to the base 11 and is symmetrically arranged with the first worm 321. It is driveably connected to both the drive assembly 31 and the second worm wheel 332. The second worm wheel 332 is connected to the second handle 132.

[0034] Thus, by using a single drive assembly 31 in conjunction with two symmetrically arranged worm gear transmission assemblies, the structure is simpler, the cost is lower, the control is more synchronized, and the reliability is higher than using two independent drivers to control the two grips separately.

[0035] Furthermore, worm gear mechanisms often have a self-locking function. When the drive assembly 31 stops working, the grip will be immediately locked in the current position and will not rotate due to external forces (such as the driver unintentionally leaning on it or vehicle vibration), thereby improving the safety of the user when using the grip assembly 13.

[0036] In addition, the small transmission backlash of the worm gear enables precise control of the grip rotation angle, ensuring that both grips can accurately reach the preset folding and unfolding positions.

[0037] like Figure 4As shown, the base 11 also includes a third hinge seat 173 and a fourth hinge seat 174. The third hinge seat 173 and the fourth hinge seat 174 are respectively fixedly connected to the base plate 111. The end of the first worm gear 321 away from the drive assembly 31 is hinged to the third hinge seat 173. The first worm gear 321 and the drive assembly 31 can be connected by means of, but not limited to, a spline connection. The end of the second worm gear 331 away from the drive assembly 31 is hinged to the fourth hinge seat 174. The second worm gear 331 and the drive assembly 31 can be connected by means of, but not limited to, a spline connection. In this way, rotation of the first worm gear 321 and the second worm gear 331 can be realized.

[0038] Combination Figure 4 , Figure 5 As shown, the first worm gear 322 is located within the first hinge seat 171. The first worm gear 322 has a first linkage hole 3221 in its center. The first linkage hole 3221 is a non-circular hole. One end of the first grip 131, hinged to the first hinge seat 171, passes through the first linkage hole 3221. When the first worm 321 drives the first worm gear 322 to rotate, the first worm gear 322 can drive the first grip 131 to rotate. Similarly, the second worm gear 332 is located within the second hinge seat 172. The second worm gear 332 has a second linkage hole 3321 in its center. The second linkage hole 3321 is a non-circular hole. One end of the second grip 132, hinged to the second hinge seat 172, passes through the second linkage hole 3321. When the second worm 331 drives the second worm gear 332 to rotate, the second worm gear 332 can drive the second grip 132 to rotate. Thus, through the cooperation of the worm gear mechanism, the grip assembly 13 can be rotated, thereby facilitating the switching of the steering wheel assembly's state.

[0039] Optionally, with Figure 5 For example, the cross-section of the first linkage hole 3221 and the second linkage hole 3321 can be a regular hexagon. Of course, other shapes are also possible, and this embodiment does not limit them.

[0040] like Figure 5 As shown, the threads of the first worm 321 and the second worm 331 are in opposite directions. Thus, when the drive assembly 31 is in operation, the first worm 321 and the second worm 331 rotate synchronously, causing the two grips to rotate in opposite directions, so that the two grips can be opened or folded synchronously.

[0041] like Figure 5 As shown, in some embodiments, at least one of the first worm gear 322 and the second worm gear 332 is a partially toothed worm gear.

[0042] like Figure 2As shown, the base 11 also includes a first protective cover 15 and a second protective cover 16. The first protective cover 15 covers the outside of the first worm 321, and the second protective cover 16 covers the outside of the second worm 331 to protect the first worm 321 and the second worm 331.

[0043] Among them, "partial toothed worm gear" refers to a worm gear that has teeth only on a specific arc segment, while the rest of the part is smooth or toothless, and the end face of the rest of the part is not lower than the end face of the tooth.

[0044] Thus, when the grip assembly 13 rotates to the preset "unfolded position" or "folded position," the worm will rotate to a position where it meshes with the toothed end of the worm wheel. At this point, the remaining part of the worm wheel will limit the worm, preventing it from meshing with the toothless part of the worm wheel and thus preventing it from continuing to drive the worm wheel to rotate. In this way, the grip assembly 13 can be limited to avoid excessive rotation and interference with other structures within the steering wheel assembly.

[0045] In some embodiments, the steering wheel assembly further includes a controller and a detection element. The detection element is capable of detecting the torque received by the drive portion of the drive assembly 31, and the controller is used to control the drive assembly 31 to stop operating when the torque obtained by the detection element is greater than a specified value.

[0046] When the worm rotates to the position where it meshes with the toothed end of the worm wheel, the torque on the drive unit of the drive assembly 31 may exceed a specified value. At this time, the controller stops the drive assembly 31 from operating, thus preventing damage to the drive assembly 31 caused by continued operation.

[0047] Of course, both the first worm gear 322 and the second worm gear 332 can be full-tooth worm gears, and their unfolded and retracted positions can be controlled by the driving angle of the drive assembly 31. This disclosure does not limit this aspect.

[0048] like Figure 4 As shown, in some embodiments, the drive assembly 31 includes a motor 311 and a reduction assembly 312. The output end of the motor 311 is connected to the input end of the reduction assembly 312, and the output end of the reduction assembly 312 is respectively connected to the first worm gear 321 and the first worm gear 321 transmission connection.

[0049] Thus, by adding the reduction gear 312, the torque transmitted to the worm gear can be further increased to ensure the smooth movement of the grip assembly 13. Furthermore, the reduction gear 312 allows the first grip 131 and the second grip 132 to rotate slowly even when the motor 311 rotates a large number of revolutions, thereby improving the stability of the rotation of the first grip 131 and the second grip 132, and enabling precise control of the rotation angle of the first grip 131 and the second grip 132.

[0050] At least one of the motor 311 and the reduction gear 312 is fixed on the base 11 to ensure the stable movement of the drive assembly 31.

[0051] Optionally, the first worm 321 is splinedly connected to the drive section of the reduction assembly 312, and the second worm 331 is splinedly connected to the drive section of the reduction assembly 312.

[0052] Optionally, the reduction gear 312 can be, for example, but not limited to, a planetary gear structure.

[0053] Combination Figures 6 to 8 As shown, in some embodiments, the base 11 includes a connected substrate 111 and a bracket 112, the display screen 12 is fixed to the substrate 111, the bracket 112 is fixed to the side of the substrate 111 away from the display screen 12, the bracket 112 is connected to the steering column 2, and at least a portion of the folding drive mechanism 3 is located within the bracket 112.

[0054] In this way, the steering column 2 and the folding drive mechanism 3 can be separated by the bracket 112 to avoid interference between them, thereby ensuring the stability of the steering wheel assembly during use. Furthermore, the bracket 112 eliminates the need for a separate area on the base plate 111 to mount the steering column 2, thus reducing the size of the base plate 111 in the direction perpendicular to the steering column 2 and improving the utilization of vehicle space.

[0055] like Figure 8 As shown, when the grip assembly 13 is in the folded position, the first grip 131 is located on the side of the bracket 112 and the steering column 2, and the second grip 132 is located on the side of the bracket 112 and the steering column 2. This allows for the reasonable use of the side section of the steering column 2 to accommodate the grip assembly 13, thereby improving the utilization rate of the vehicle body space.

[0056] Combination Figure 6 , Figure 7 As shown, in some embodiments, the bracket 112 has a mounting hole 1121 that accommodates the end of the steering column 2, and the inner wall of the mounting hole 1121 is splinedly connected to the outer peripheral wall of the steering column 2. The steering wheel body 1 also includes a screw 14, the rod 141 of which is located inside the steering column 2 and threadedly connected to the inner wall of the steering column 2, and the nut 142 of the screw 14 abuts against the surface of the bracket 112 away from the steering column 2.

[0057] The outer peripheral wall of the steering column 2 is splined to the inner wall of the mounting hole 1121, which can restrict the relative rotation between the steering column 2 and the bracket 112. At the same time, the screw 14 is threaded to the inner wall of the steering column 2 and abuts against the surface of the bracket 112 away from the steering column 2, which can restrict the relative axial displacement between the steering column 2 and the bracket 112. This ensures that when the grip assembly 13 is rotated, the steering column 2 can rotate stably and synchronously with the grip assembly 13, thereby improving the stability of the steering wheel assembly movement.

[0058] like Figure 7 As shown, a portion of the mounting hole 1121 on the side away from the substrate 111 has a funnel-shaped opening, and a portion of the outer wall of the steering column 2 is in contact with the inner wall of the funnel-shaped opening.

[0059] Thus, during the installation of the steering wheel assembly, the flared opening allows the end of the steering column 2 to enter the mounting hole 1121 more smoothly, thereby improving the convenience of connecting the steering column 2 and the bracket 112.

[0060] like Figure 8 As shown, in some embodiments, the steering wheel assembly also includes a clock spring 5, which is sleeved on the outside of the steering column 2 and is used to connect to the wiring harness 4 inside the steering wheel assembly.

[0061] Thus, the clock spring 5 can prevent the wiring harness 4 from being broken when the steering wheel body 1 is turned, thereby improving the stability of the steering wheel assembly during use.

[0062] For example, such as Figure 8 As shown, the wiring harness 4 may include the wiring harness 4 of the motor 311 and the wiring harness 4 of the display screen 12. Of course, the wiring harness 4 may also include other wiring harnesses, and this embodiment does not limit this.

[0063] Based on the same concept, this disclosure also provides a vehicle. For example... Figure 1 As shown, the vehicle includes a trim frame 6 and the aforementioned steering wheel assembly. The trim frame 6 has a clearance hole 61, the size of which is adapted to the base 11. The steering wheel assembly has a folded-down position and a released position. In the folded-down position, the grip assembly 13 is in a folded position and the display screen 12 is at least partially located within the clearance hole 61. In the released position, the grip assembly 13 is in an unfolded position and the display screen 12 is located on the side of the clearance hole 61 away from the steering column 2.

[0064] Thus, by simply aligning the clearance hole 61 with the base 11, the need for the steering wheel assembly to switch between the retracted and released states can be met, without requiring the clearance hole 61 to be perfectly matched to the overall size of the steering wheel assembly. This avoids the steering wheel assembly occupying excessive space within the vehicle's interior in the direction perpendicular to the steering column 2, thereby optimizing the interior space. Furthermore, the switching process of the steering wheel assembly is technologically advanced, enhancing the user experience.

[0065] Furthermore, when the steering wheel assembly is in the retracted position, the display screen 12 on the steering wheel integrates seamlessly with the vehicle's center console or dashboard trim, becoming part of the overall interior design and significantly enhancing visual appeal and technological sophistication. In addition, in this state, the display screen 12 transcends the limitations of a mere "steering wheel monitor," transforming into a shared, immersive infotainment display screen 12. This allows the driver to watch movies and browse information while in autonomous driving mode without being distracted by the shape and position of the steering wheel, thus improving the driver's user experience.

[0066] like Figure 1 As shown, in some embodiments, the top surface of the trim frame 6 has a dashboard 62 for displaying the vehicle's driving status.

[0067] Thus, by setting a fixed instrument panel 62 on the trim frame 6 integrated with the steering wheel, a core information display center is established for the vehicle that is always visible regardless of the steering wheel's position. This ensures that vehicle status information is always displayed when the steering wheel assembly is in the retracted position and the user is using the display screen 12 for entertainment activities, providing crucial safety redundancy. Furthermore, it ensures the continuity, safety, and logical clarity of human-machine interaction across different driving modes, thereby fully realizing the ultimate experience of intelligent cockpit mode switching.
