[0036] The specific embodiments of this disclosure will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit this disclosure.

[0037] In this disclosure, terms such as “upper,” “lower,” “front,” “back,” “inner,” “outer,” and “circumferential” are used to indicate direction or positional relationship. Since components of the described device can be positioned in multiple different orientations, these directional terms are for illustrative purposes and not restrictive. It should be understood that other aspects can be utilized and structural or logical changes can be made without departing from the concept of this disclosure. Therefore, the following detailed description should not be considered limiting.

[0038] It should be noted that, Figure 1The folded state of the steering mechanism and the base is shown. Figure 2 The diagram shows the unfolded state of the steering mechanism and the base phase. Figure 3 One implementation of the first track and the tracking device is shown. Figure 4 Another implementation of the first track is shown. Figure 5 Another implementation of the first track and the tracking device is shown.

[0039] Reference Figures 1 to 13 The present disclosure provides a steering device, which includes a base 1 and a steering mechanism 2.

[0040] The steering mechanism 2 includes a slide 21 and a steering wheel assembly 22 rotatably connected to the slide 21. The steering wheel assembly 22 has a tracking element 23. The slide 21 is slidably connected to the base 1.

[0041] The base 1 has a first track 11, and the tracking member 23 is slidably connected to the first track so as to drive the steering wheel assembly 22 to rotate relative to the slide 21.

[0042] By utilizing the above technical solution, the first track 11 participates in the storage process of the steering wheel assembly 22 and changes its movement trajectory, thereby improving operational stability and accuracy, simplifying the number of parts, and reducing space occupation. For example, when the steering wheel assembly 22 moves with the slide 21, the first track 11 guides the movement of the tracking member 23, causing the steering wheel assembly 22 to rotate relative to the slide 21, thus improving the movement posture of the steering wheel assembly 22. In this way, by changing the movement trajectory / posture of the steering wheel assembly 22 through the sliding cooperation of the first track 11 and the tracking member 23, for example, the steering wheel assembly 22 can achieve better stability and accuracy. During the storage or unfolding process, the steering wheel assembly 22 can avoid obstacles it may encounter. For example, by rotating the steering wheel assembly 22, it can be switched to a retractable state for storage, such as folding. By changing the movement posture of the steering wheel assembly 22 through the first track 11, it can avoid obstacles (such as the dashboard) that may be encountered during the folding process of the steering wheel 22 in the retractable state. Alternatively, by rotating the steering wheel, it can be switched to an unfoldable state for unfolding, providing more unfolding space and avoiding interference with other obstacles. Therefore, the steering device and vehicle disclosed herein have a more streamlined and ingenious structure, fewer parts, smaller footprint, and can significantly improve the operational stability and accuracy of the steering wheel assembly 22 during trajectory changes. It can also be adapted to vehicles with lower dashboards, greatly improving the utilization of cockpit space and user experience.

[0043] In some possible implementations, the slide 21 is reciprocally slidably connected to the base 1 along a first direction X, the first track 11 has a first track segment 111, the extension direction of the first track segment 111 is different from the first direction X, and the tracking member 23 can slide along the first track segment 111 to drive the steering wheel assembly 22 to rotate relative to the slide 21. Thus, in, for example... Figure 1 Taking the front-to-back direction as an example, "front" can refer to the front of the vehicle, i.e., the side where the front of the car is located, and "back" can refer to the rear of the vehicle, i.e., the side where the rear of the car is located. When the slide 21 slides forward along the first direction X, and the tracking member 23 slides synchronously along the first track segment 111, the steering wheel assembly 22 will rotate relative to the slide 21, for example, rotating downward. In this way, the steering wheel 222 in the steering wheel assembly 22 can move forward and downward at the same time to make way for the space above the steering wheel 222 or the dashboard above the steering wheel 222, so that the steering wheel 222 can be folded for storage. For example, when the slide 21 slides backward along the first direction X, and the tracking member 23 slides synchronously along the first track segment 111, the steering wheel assembly 22 can rotate relative to the slide 21, for example, rotating upward. In this way, the steering wheel 222 can move upward and backward at the same time, so that the steering wheel 222 has sufficient space when unfolded.

[0044] Reference Figure 3 In some possible implementations, the first track segment 111 has a first end 1111 and a second end 1112, with the second end 1112 being higher than the first end 1111 in the height direction Z. This allows the tracking member 23 to drive the steering wheel assembly 22 to rotate downwards when moving from the first end 1111 to the second end 1112, and to drive the steering wheel assembly 22 to rotate upwards when moving from the second end 1112 to the first end 1111. Specifically, when the tracking member 23 moves from the first end 1111 to the second end 1112, it can be guided to move upwards, thereby causing the steering wheel assembly 22 to rotate downwards. This facilitates the folding of the steering wheel 222, reducing its space under the driver's cab, adapting to vehicles with lower dashboards, and significantly improving the utilization of the cockpit space and user experience. When the tracking member 23 moves from the second end 1112 to the first end 1111, it can guide the tracking member 23 to move to a lower position, thereby causing the steering wheel assembly 22 to rotate upward so that the steering wheel assembly 22 can be used normally after it is unfolded.

[0045] Reference Figure 3In some possible implementations, the first track 11 further includes a second track segment 112 connected to a first end 1111 of the first track segment 111. The second track segment 112 extends along a first direction X. The tracking member 23 can slidably reciprocate on the first track segment 111 and the second track segment 112. When the tracking member 23 is slidably connected to the second track segment 112, the steering wheel assembly 22 is in an unfoldable state. Thus, the second track segment 112 not only serves as a guide when the steering mechanism 2 is folded with the base 1, but also adjusts the position of the steering wheel 222 in the fore-and-aft direction to meet the space and driving position requirements of the occupants in the passenger compartment. Furthermore, it can further simplify the structure of the steering device and reduce the number of parts used.

[0046] Reference Figure 3 In some possible implementations, the second track segment 112 extends in a straight line along the first direction X. Thus, the steering wheel assembly 22 can move in the fore-and-aft direction to fold with the base 1 and / or adjust the position of the steering wheel 222 within the passenger compartment.

[0047] Reference Figure 3 In some possible implementations, the first track segment 111 extends upward in a curved manner from the first end 1111 away from the second track segment 112. Thus, when the steering mechanism 2 and the base 1 are folded, the portion of the steering wheel assembly 22 where the steering wheel 222 is located can rotate downward, and the height of the steering wheel 222 can be lowered.

[0048] Thus, the first track 11, through the first track segment 111 and the second track segment 112, achieves a smooth transition of the steering wheel 222 first moving forward and then folding in a curve, effectively avoiding interference from internal components. Compared with the prior art, the steering device disclosed in this invention significantly improves the accuracy and stability of the motion trajectory, not only maximizing the space utilization inside the dashboard, but also ensuring the controllability of the steering wheel 222's posture during folding and storage, providing greater flexibility for cockpit layout design.

[0049] Reference Figure 3 , Figure 4 and Figure 5 In some possible embodiments, the base 1 includes a bottom plate 12 and a side plate 13 connected together. A slide block 21 is slidably connected to the bottom plate 12 and / or the side plate 13. A first track 11 is disposed on the side plate 13. The first track 11 is constructed as a slide rail protruding from the side plate 13 or a slide groove recessed into the side plate 13. The tracking member 23 includes a sliding portion 233 slidably connected to the slide rail or the slide groove. In this way, the base 1 and the first track 11 can be constructed.

[0050] It should be noted that the sliding part 233 can be constructed in any suitable structure and made of any suitable material, and this disclosure does not impose any specific limitations on it. For example, the sliding part 233 can be constructed as a pulley in a groove, or it can be constructed as a pulley that slides along the sides of the slide rail in the vertical direction.

[0051] Reference Figure 3 In some possible implementations, the side plate 13 includes a detachably connected first side plate 131 and a second side plate 132. The second side plate 132 is connected between the base plate 12 and the first side plate 131. A second track segment 112 is formed on the first side plate 131, and the first track segment 111 is at least partially formed on the second side plate 132. Thus, the second side plate 132 can be detached according to the height of the vehicle's dashboard. When the steering wheel assembly 22 needs to rotate and the steering wheel 222 needs to move downwards, the second side plate 132 can be installed on the first side plate 131. When the steering wheel assembly 22 does not need to rotate and the steering wheel 222 does not need to move downwards, the second side plate 132 does not need to be installed. In this case, the folding of the steering structure and the base 1 can be achieved by sliding the slide block 21 on the base 1. Therefore, setting the side plate 13 as a detachably connected first side plate 131 and second side plate 132 can further improve the adaptability of the steering device.

[0052] It should be noted that the first side plate 131 and the second side plate 132 can be detachably connected using any suitable structure, and this disclosure does not impose any specific limitations on this. For example, the first side plate 131 and the second side plate 132 can be detachably connected by bolts.

[0053] Reference Figure 3 In some possible implementations, side plates 13 are provided on both sides of the base plate 12 opposite to each other along the second direction Y. In this way, the aforementioned first track 11 and sliding part 233 can be arranged in pairs on the side plates 13 on both sides of the base plate 12, further improving the stability of the steering device when folding the steering mechanism 2.

[0054] Reference Figure 3 In some possible implementations, the traction control 23 includes a mounting plate 231 and connecting plates 232 located on both sides of the mounting plate 231. The connecting plates 232 are provided with sliding portions 233. The mounting plate 231 is connected to the steering column assembly 221 of the steering wheel assembly 22. In this way, the traction control 23 can be constructed.

[0055] Reference Figure 3In some possible implementations, a buffer structure 2111 is provided between the tracking element 23 and the slide 21. Thus, the buffer structure 2111 can absorb the impact and vibration between the tracking element 23 and the slide 21, reducing noise and improving the reliability and service life of the tracking element 23, the slide 21, and the steering mechanism. Furthermore, it greatly improves NVH performance and user experience.

[0056] It should be noted that the buffer structure 2111 can be constructed in any suitable form and made of any suitable material, and this disclosure does not impose any specific limitations on it. For example, the buffer structure 2111 can be constructed as a disc spring or as a hydraulic damper.

[0057] Reference Figure 3 and Figure 12 In some possible implementations, a wear-resistant structure 133 is provided between the slide 21 and the base plate 12 and / or the side plate 13. This effectively reduces the coefficient of friction between the slide 21 and the base plate 12 and / or the side plate 13, preventing a decrease in accuracy due to wear, while improving the reliability and service life of the slide 21 and the base plate 12 and / or the side plate 13.

[0058] It should be noted that the wear-resistant structure 133 can be constructed in any suitable form, using any suitable material, and connected to the base plate 12 and / or side plate 13 via any suitable structure; this disclosure does not impose any specific limitations in this regard. For example, the wear-resistant structure 133 can be constructed as a liner. The wear-resistant structure 133 can be constructed as a multi-layered structure, with an internal steel structure and an external PUM (Polyurethane Microcellular) material. Furthermore, PUM has a self-lubricating function to improve the sliding stability of the slide block 21. Alternatively, the wear-resistant structure 133 can be made of metal materials such as steel, titanium, or manganese. The wear-resistant structure 133 can be connected to the base plate 12 and / or side plate 13 via fasteners such as screws, or the wear-resistant structure 133 can also be connected to the slide block 21 via fasteners such as screws.

[0059] Reference Figure 13 In some possible implementations, a reinforcing rib 121 is provided on the side of the base plate 12 facing away from the accommodating space to improve the structural strength of the base plate 12, and at the same time, it can play a role in assisting assembly and positioning, thereby reducing manufacturing costs while ensuring performance.

[0060] In some possible implementations, a position sensor is provided on the side of the floor 12 facing away from the accommodating space. This sensor is electrically connected to the vehicle's control unit and / or the seat, and can transmit detection signals to the vehicle's control unit to interact with the seat, thereby enhancing the vehicle's intelligence and the user experience.

[0061] Reference Figure 3 In some possible implementations, a second track 15 extending along the first direction X is provided on the base plate 12 and / or side plate 13, and the slide 21 is slidably connected to the second track. In this way, the slide 21 can be slidably connected to the base 1, and the accuracy of the sliding path of the slide 21 can be improved, thereby improving the sliding stability of the slide 21.

[0062] Reference Figure 6 In some possible implementations, the slide 21 includes a seat 211 and a bracket 212 disposed above the seat 211. The steering wheel assembly 22 includes a steering column assembly 221 and a steering wheel 222 located above the seat 211. The steering column assembly 221 is hinged to the bracket 212, and the steering wheel 222 is connected to one end of the hinge between the steering column assembly 221 and the bracket 212. The tracking element 23 is connected to the other end of the hinge between the steering column assembly 221 and the bracket 212. Thus, when the tracking element 23 slides along the first track segment 111, the steering wheel assembly 22 can rotate around the hinge between the steering column assembly 221 and the bracket 212 and switch to a retractable state, so that the steering wheel 222 moves downward.

[0063] Reference Figure 3 In some possible implementations, the steering column assembly 221 includes a hand-feed motor 2211 hinged to a bracket 212. Thus, the hand-feed motor 2211 can follow and connect to the steering wheel 222, acquiring steering signals from the steering wheel 222. Furthermore, the hand-feed motor 2211 can provide tactile feedback to the user, enhancing the driving experience.

[0064] It should be noted that the hand-feed motor 2211 can be installed in any suitable position, and this disclosure does not impose any specific limitations on it. For example, the hand-feed motor 2211 can be installed on the mounting plate 231 by bolts.

[0065] It should also be noted that the steering wheel 222 can be connected to the steering column assembly 221 in any suitable manner. For example, the steering wheel 222 can be hinged to the steering column assembly 221 about an axis parallel to the width direction of the vehicle, so as to facilitate the folding of the steering wheel 222 relative to the steering column assembly 221. For example, in the retractable state, the steering wheel 222 can be rotated upward relative to the steering column assembly 221 and folded; in the unfolded state, the steering wheel 222 can be reset, so that the vehicle can be controlled to turn left or right or drive straight by rotating the steering wheel 222. This disclosure does not make specific limitations in this regard; the purpose is simply to achieve the folding of the steering wheel 222. This disclosure can reduce the height of the steering wheel 222 to avoid interference with structures such as the instrument panel, thereby facilitating the folding of the steering wheel 222.

[0066] Reference Figure 1 and Figure 2 In some possible implementations, the steering system further includes a mounting bracket 3 for connection to the vehicle body. The base 1 is rotatably connected to the mounting bracket 3 to drive the steering wheel assembly 22 to rotate upwards or downwards. Thus, the base 1 can drive the steering mechanism 2 to rotate upwards or downwards relative to the mounting bracket 3 to adjust the pitch angle of the steering wheel 222, thereby improving the driving experience for passengers. During the folding process of the steering mechanism 2 and the base 1, the steering wheel 222 can be lowered to a lower position to further adapt to vehicles with lower dashboards, further improving the adaptability of the steering system.

[0067] Furthermore, this disclosure achieves decoupled control of motion degrees of freedom through the independent driving of the first drive component 4 and the second drive component 7, significantly simplifying the folding logic of the steering mechanism 2 and the base 1. Compared with traditional mechanical linkage, the steering device of this disclosure responds faster, has higher control precision, effectively avoids motion interference, improves the reliability and user experience of automated folding and storage, and reduces the energy consumption of the steering device during the folding and storage process.

[0068] It should be noted that the vehicle body may include an instrument panel, and a tubular beam may be installed inside the instrument panel. A mounting bracket may be connected to the tubular beam. The mounting bracket 3 and the tubular beam can be connected using any suitable structure, and this disclosure does not impose any specific limitations on this. For example, the mounting bracket 3 and the tubular beam may be connected by bolts.

[0069] Reference Figure 7 , Figure 8 , Figure 9 and Figure 10 In some possible implementations, the steering device further includes a first drive assembly 4 connected between the vehicle body and the base 1 to drive the base 1 to rotate relative to the mounting bracket 3. This allows the base 1 to drive the steering wheel assembly 22 to rotate upwards or downwards.

[0070] Reference Figure 7 , Figure 8 , Figure 9 and Figure 10 In some possible implementations, the steering device further includes a first transmission assembly 5, through which the first drive assembly 4 drives the base 1 to rotate relative to the mounting bracket 3. Thus, the first transmission assembly 5 allows the first drive assembly 4 to be positioned appropriately according to actual conditions, improving the space utilization of the steering device and reducing its size.

[0071] Reference Figure 7 , Figure 8 , Figure 9 and Figure 10In some possible implementations, the first drive assembly 4 includes a first drive member 41 and a first reduction assembly 42, with the first drive member 41 connected to the first transmission assembly 5 or the base 1 via the first reduction assembly 42. Thus, the first reduction assembly 42 can adjust the output torque of the first drive assembly 4 to the value required for the base 1 and the steering mechanism 2 to rotate together, meeting design requirements and improving the stability of the rotation of the base 1 and the steering mechanism 2.

[0072] Reference Figure 7 , Figure 8 , Figure 9 and Figure 10 In some possible implementations, the first drive component 41 includes a first motor 411, and the first reduction assembly 42 includes a first intermediate shaft 421 and a primary gear 422 and a secondary gear 423 disposed on the first intermediate shaft 421. The first motor 411 is driven and connected to the primary gear 422, and the secondary gear 423 is driven and connected to the first transmission assembly 5. Thus, the first reduction assembly 42 can regulate the output torque of the first drive assembly 4. Furthermore, the first reduction assembly 42 achieves multi-stage reduction and torque amplification through the first intermediate shaft 421, the primary gear 422, and the secondary gear 423, further improving the rotational stability of the base 1 and the steering mechanism 2. The first reduction assembly 42 also has a self-locking function through the first intermediate shaft 421, the primary gear 422, and the secondary gear 423, improving the stability of the steering wheel 222 during vehicle operation.

[0073] It should be noted that the secondary gear 423 and the first transmission assembly 5 can adopt any suitable connection method, and this disclosure does not impose any specific limitations on this. For example, the secondary gear 423 can mesh with a gear connected to the lead screw in the following embodiment. The teeth of the secondary gear 423 are helical teeth.

[0074] It should also be noted that the primary gear 422 and the first motor 411 can be connected in any suitable manner, and this disclosure does not impose any specific limitations on this. For example, the motor shaft of the first motor 411 can be a worm gear, and the primary gear 422 is meshed with and connected to the motor shaft of the first motor 411.

[0075] Reference Figure 7 , Figure 8 , Figure 9 and Figure 10 In some possible implementations, the first transmission assembly 5 includes a first linkage mechanism 51, and the first drive assembly 4 is driven to the base 1 via the first linkage mechanism 51. Thus, the first drive assembly 4 can drive the base 1 to rotate the steering wheel assembly 22 upwards or downwards.

[0076] Reference Figure 7 , Figure 8 , Figure 9 and Figure 10 In some possible implementations, the first linkage mechanism 51 includes a rocker arm 511 and an actuating rod 512. The first connecting portion 5111 of the rocker arm 511 is hinged to the vehicle body, the second connecting portion 5112 of the rocker arm 511 is hinged to the first drive assembly 4, and the third connecting portion 5113 of the rocker arm 511 is connected to the actuating rod 512. The actuating rod 512 is slidably connected to the base 1. The first drive assembly 4 drives the rocker arm 511 to rotate about the first connecting portion 5111 through the second connecting portion 5112, so as to drive the base 1 to rotate relative to the mounting bracket 3 through the actuating rod 512.

[0077] It should be understood that the process of the first drive assembly 4 driving the base 1 to rotate the steering wheel assembly 22 upward or downward is as follows: the first drive assembly 4 drives the rocker arm 511 to rotate around the first connecting part 5111 through the first deceleration assembly 42 and the first transmission assembly 5. The rocker arm 511 can drive the actuating rod 512 to slide relative to the base 1 and rotate around the first connecting part 5111 through the third connecting part 5113. In this way, the actuating rod 512 can drive the base 1 and the steering mechanism 2 to rotate around the rotational connection between the base 1 and the mounting bracket 3.

[0078] It should be noted that the vehicle body may include an instrument panel, and a tube beam may be installed inside the instrument panel. In some embodiments, the first connecting portion 5111 may be hinged to a connecting bracket 54, which is connected to the tube beam. Exemplarily, the connecting bracket 54 may be connected to the tube beam by bolts and a locating pin, or the connecting bracket 54 may be connected to the tube beam by a disassembly clip, for ease of after-sales maintenance. The locating pin serves as a priority positioning element, facilitating the connection between the connecting bracket 54 and the tube beam by bolts. Alternatively, in another embodiment, the first connecting portion 5111 may be directly hinged to the tube beam; this disclosure does not specifically limit this aspect.

[0079] It should also be noted that the actuator rod 512 and the base 1 can adopt any suitable sliding connection method, and this disclosure does not limit this. For example, the base 1 has a protruding actuator base 18 with a sliding hole, and the actuator rod 512 passes through the sliding hole. Furthermore, the actuator rod 512 can be made of 65 manganese and / or POM (polymerized formaldehyde), or the portion of the actuator rod 512 that contacts the actuator base 18 can be covered with a slider made of 65 manganese and / or POM (polymerized formaldehyde) to improve the wear resistance of the actuator rod 512 and enhance the reliability and service life of the steering device.

[0080] Reference Figure 7 , Figure 8 , Figure 9 and Figure 10In some other embodiments, the number of rocker arms 511 and connecting brackets 54 may be correspondingly set to two, with one rocker arm 511 located at one end of the actuating rod 512 and the other rocker arm 511 located at the other end of the actuating rod 512. The first drive assembly 4 or the nut 53 of the following embodiments is connected to the second connecting portion 5112 of one of the rocker arms 511.

[0081] In some other embodiments, the number of actuators 512 can be set to multiple to form a multi-link structure, enabling the base 1 to achieve more spatial movement and multi-angle adjustment in three-dimensional space.

[0082] Reference Figure 7 , Figure 8 , Figure 9 and Figure 10 In some possible implementations, the first transmission assembly 5 includes a lead screw 52 and a lead screw nut 53. A first drive assembly 4 is driven to the lead screw 52 to drive the lead screw 52 to rotate. The lead screw nut 53 is threaded to the lead screw 52 to be able to move along the axial direction of the lead screw 52. The lead screw nut 53 is connected to a second connecting portion 5112. The first drive assembly 4 drives the rocker arm 511 to rotate around the first connecting portion 5111 via the lead screw nut 53, thereby driving the base 1 to rotate relative to the mounting bracket 3 via the actuating rod 512. In this way, the first transmission assembly 5 can transmit the force of the first deceleration assembly 42 to the rocker arm 511.

[0083] It should be noted that the nut 53 is hinged to the second connecting portion 5112. The nut 53 can be hinged to the second connecting portion 5112 with any suitable structure, and this disclosure does not specifically limit it. For example, as shown... Figure 8 and Figure 10 As shown, the second connecting part 5112 is constructed as a hinge frame, and the nut 53 is hinged to the hinge frame. Alternatively, as... Figure 9 As shown, the second connecting part 5112 is hinged to a hinge frame, and the nut 53 is connected to the hinge frame.

[0084] Reference Figure 6 , Figure 11 , Figure 12 and Figure 13 In some possible implementations, the steering device further includes a second drive assembly 7, which is drivenly connected to the slide 21 to drive the slide 21 to move along the first direction X. Thus, the second drive assembly 7 can drive the slide 21 to slide along the first direction X on the base 1.

[0085] Reference Figure 6 , Figure 11 , Figure 12 and Figure 13In some possible implementations, the steering device further includes a second drive assembly 7 and a second transmission assembly 8. The second drive assembly 7 is driven to the slide 21 via the second transmission assembly 8 to drive the slide 21 to move along the first direction X. In this way, the second transmission assembly 8 allows the second drive assembly 7 to be positioned appropriately according to actual conditions, improving the space utilization of the steering device and reducing its size.

[0086] It should be noted that the second drive assembly 7 can be set in any suitable position according to the actual situation, and this disclosure does not make any specific limitation. For example, the base 1 has an internal space 14 that accommodates the slide 21 and the tracking member 23, and the second drive assembly 7 is set on the outer wall of the base 1 away from the internal space 14.

[0087] Reference Figure 6 , Figure 11 , Figure 12 and Figure 13 In some possible implementations, the second drive assembly 7 includes a second drive member 71 and a second reduction assembly 72. The second drive member 71 is connected to the second transmission assembly 8 or the slide 21 via the second reduction assembly 72. In this way, the second reduction assembly 72 can adjust the output torque of the second drive assembly 7 to the value required for the slide 21 to slide along the base 1, thereby meeting design requirements and improving the stability of the slide 21.

[0088] Reference Figure 6 , Figure 11 , Figure 12 and Figure 13 In some possible implementations, the second drive component 71 includes a second motor 711, and the second reduction assembly 72 includes a second intermediate shaft 721 and a primary transmission gear and a secondary transmission gear 722 disposed on the second intermediate shaft 721. The second motor 711 is driven and connected to the primary transmission gear, and the secondary transmission gear 722 is driven and connected to the second transmission assembly 8. Thus, the second reduction assembly 72 can adjust the output torque of the second motor 711 to regulate the output torque of the first drive component 41. Furthermore, the second reduction assembly 72 achieves multi-stage reduction and torque amplification through the second intermediate shaft 721, the primary transmission gear, and the secondary transmission gear 722, further improving the stability of the slide block 21 sliding along the base 1. The first reduction assembly 42 also has a self-locking function through the first intermediate shaft 421, the primary gear 422, and the secondary gear 423, improving the stability of the steering wheel 222 during vehicle operation.

[0089] Reference Figure 6 , Figure 11 , Figure 12 and Figure 13In some possible implementations, the second transmission assembly 8 includes a second linkage mechanism 81, which includes a first link 811. One end of the first link 811 is connected to the slide block 21, and the other end is connected to the second drive assembly 7. Thus, the second drive assembly 7 can pull the slide block 21 to slide along the base 1 via the first link 811.

[0090] For example, the first link 811 may be hinged to the slide 21.

[0091] Reference Figure 6 , Figure 11 , Figure 12 and Figure 13 In some possible embodiments, the second transmission assembly 8 includes a second linkage mechanism 81, which includes a first link 811 and a second link. One end of the first link 811 is hinged to the slide 21, and the other end is hinged to the second link. A rack structure 8121 is provided on the second link. The second drive assembly 7 engages with the rack structure 8121 via a transmission gear. Thus, the second drive assembly 7 can drive the transmission gear to rotate via the second reduction assembly 72, which in turn drives the rack structure 8121 to pull the first link 811 to move. It should be noted that the transmission gear can be the aforementioned two-stage transmission gear 722. In other embodiments, the second drive component 71 may include a second motor 711, and the output shaft of the second motor 711 is connected to the rack structure 8121 via a transmission gear.

[0092] Reference Figure 6 , Figure 11 , Figure 12 and Figure 13 In some possible embodiments, the second connecting rod 812 is provided with a guide portion 8122, and the base 1 is provided with an arc-shaped guide groove 16 extending circumferentially around the transmission gear and a linear guide groove 17 extending along the first direction X and communicating with one end of the arc-shaped guide groove 16. The guide portion 8122 is slidably connected to the arc-shaped guide groove 16 and the linear guide groove 17. The guide portion 8122 is located between the rack structure 8121 and the end of the second connecting rod connected to the first connecting rod 811.

[0093] It should be understood that the arrangement of the guide section 8122 and the linear guide groove 17 can improve the force transmission stability of the second transmission assembly 8.

[0094] Furthermore, during the process of the second drive assembly 7 pulling the slide 21 via the first link 811 and the second link 812, when the guide part 8122 moves to the connection point of the arc-shaped guide groove 16 and the linear guide groove 17, the second motor 711 continues to rotate. The secondary transmission gear 722 can provide a force to the second link 812 to rotate around the second intermediate shaft 721 through the rack structure 8121. Consequently, the second link can drive the slide 21 to continue sliding in the direction of folding with the base 1 via the first link 811. Thus, through the hinged connection of the first link 811 and the second link 812, and the arrangement of the guide part 8122 and the arc-shaped guide groove 16, the second transmission assembly 8 can achieve a longer sliding stroke for the slide 21 in a smaller space, thereby further reducing the volume of the steering device.

[0095] It should be noted that the guide part 8122 can be constructed in any suitable structure, and this disclosure does not impose any specific limitations on it. For example, the guide part 8122 can be constructed as a bearing on the second connecting rod, and the bearing can be a silent bearing.

[0096] Reference Figure 6 , Figure 11 , Figure 12 and Figure 13 In some possible embodiments, a fixed bracket 19 is provided on the base, and a bearing sleeved on the fixed bracket 19 is provided on the fixed bracket 19. In this way, by fixing the second intermediate shaft 721 with the fixed bracket 19, the engagement of the guide part 8122 with the arc-shaped guide groove 16 and the linear guide groove 17, and the connection of the slide 21 to the second link 812 via the first link 811, the engagement between the rack structure 8121 and the transmission gear can be limited, so that the rack structure 8121 and the transmission gear can always be in a meshing state.

[0097] It should be noted that the fixing bracket 19 can be constructed in any suitable shape, and this disclosure does not impose any specific limitation thereon. For example, the fixing bracket 19 can be constructed as a strip or as a triangle. In addition, the bearing can be a silent bearing.

[0098] Reference Figure 1 and Figure 2 In some possible implementations, a controller 6 is also provided on the outer wall of the substrate 1, and the controller 6 is signal-connected to the first drive component 4 and the second drive component 7. In this way, the controller 6 can control the first drive component 4 and the second drive component 7 to perform corresponding actions.

[0099] It should be noted that in the above embodiments, connections not specifically described, such as the connection between the controller 6 and the base 1, the connection between the first motor 411, the first reduction assembly 42 and the base 1, and the connection between the second motor 711, the second reduction assembly 72 and the base 1, can all be made using bolts or screws. This disclosure does not specifically limit these connections and only provides illustrative examples. Furthermore, the rotating connections, hinges, and other movable connections described in the above embodiments can be made using bolts or rotating pins. This disclosure does not specifically limit these connections and only provides illustrative examples.

[0100] In some other embodiments, the difference from the above embodiments is that the first motor 411 can directly drive the slide 21 to slide along the first direction X. The second motor 711 can also directly drive the rocker arm 511 to rotate. Of course, in other embodiments, the first motor 411 or the second motor 711 can be replaced by a telescopic pole, a telescopic cylinder, or a hydraulic cylinder.

[0101] In some other embodiments, the difference from the above embodiments is that the second motor 711, the second reduction assembly 72, the first connecting rod 811 and the second connecting rod 812 can be replaced with a belt structure, with the two pulleys of the belt structure arranged on the base 1 along the first direction X, and the slide 21 connected to the belt, so as to effectively reduce the operating noise.

[0102] In some other embodiments, the sliding connection between the steering mechanism 2 and the base 1 can be optimized as a rotational folding or a flip-folding mechanism.

[0103] In some other embodiments, a torque limiter may be connected between the first motor 411 and the first reduction gear 42, and / or between the second motor 711 and the second reduction gear 72, to prevent the power output path of the first motor 411 and / or the second motor 711 from jamming, thereby improving the service life of the first motor 411 and / or the second motor 711.

[0104] In summary, referring to Figures 1 to 13 In the steering device of this disclosure, the folding process of the steering mechanism 2 and the base 1 is as follows: the second drive assembly 7 first drives the slide 21 and the steering wheel assembly 22 to slide forward. Then, under the action of the tracking member 23 and the first track segment 111, the portion of the steering wheel assembly 22 with the sliding part 233 is raised, and the portion of the steering wheel assembly 22 with the steering wheel 222 is lowered. At this time or afterward, the second drive assembly 7 actuates to cause the entire base 1 and the steering mechanism 2 to rotate downward around the hinge point of the base 1 and the mounting bracket 3. Thus, the folding movement of the steering mechanism 2 and the base 1 is completed. In addition, it should be noted that the folding of the steering wheel 222 relative to the steering column can be performed before, after, or simultaneously with the folding process of the steering mechanism 2 and the base 1, and this disclosure does not specifically limit this.

[0105] This disclosure also provides a vehicle that includes the aforementioned steering device. Thus, the vehicle also possesses the beneficial technical effects of the aforementioned steering device.

[0106] The preferred embodiments of this disclosure have been described in detail above with reference to the accompanying drawings. However, this disclosure is not limited to the specific details of the above embodiments. Within the scope of the technical concept of this disclosure, various simple modifications can be made to the technical solutions of this disclosure, and these simple modifications all fall within the protection scope of this disclosure.

[0107] It should also be noted that the various specific technical features described in the above embodiments can be combined in any suitable manner without contradiction. To avoid unnecessary repetition, this disclosure will not describe the various possible combinations separately.

[0108] Furthermore, various different embodiments of this disclosure can be combined in any way, as long as they do not violate the spirit of this disclosure, they should also be regarded as the content disclosed in this disclosure.
