Description

Technical Field

[0001] This utility model relates to the field of vehicle technology, specifically to a concealable emergency steering column device and a vehicle. Background Technology

[0002] With the intelligent and automated development of the automotive industry, autonomous driving technology is gradually moving from research and development to practical application. In fully autonomous driving scenarios, traditional steering columns are often idle, not only occupying interior space and increasing vehicle weight and cost, but also limiting the flexibility and design freedom of the interior layout. However, in special circumstances such as system failures, extreme road conditions, traffic accidents, or when after-sales personnel need to intervene in driving for maintenance and debugging, there is an urgent need for steering columns to enable manual control.

[0003] If the steering column could be hidden in autonomous driving mode to save interior space, and if the steering column could be quickly and easily pulled out and fitted with a steering wheel when the vehicle encounters an abnormal situation or requires manual driving intervention, the safety and practicality of the vehicle would be greatly improved.

[0004] However, among related technologies, there is a lack of a steering column solution that can meet the needs of both autonomous driving and emergency manual driving, flexibly switch between different states, and has a compact structure. Utility Model Content

[0005] In view of this, the present invention provides a concealable emergency steering column device and vehicle to solve the problem of how the steering column can meet the needs of both unmanned driving and emergency manual driving, flexibly switch between different states, and have a compact structure.

[0006] In a first aspect, this utility model provides a concealable emergency steering column device, comprising:

[0007] A fixing plate, suitable for fixed connection with an external structure;

[0008] The first slide plate is slidably connected to the fixed plate, and the first slide plate is provided with a drive component fixing bracket;

[0009] The second slide plate is slidably connected to the first slide plate and is equipped with a connector fixing bracket;

[0010] The driving component is mounted on the driving component mounting bracket;

[0011] Steering wheel connector, suitable for connecting a steering wheel; the steering wheel connector is mounted on a connector mounting bracket.

[0012] A first drive rod and a second drive rod, one end of the first drive rod is connected to a fixed plate, one end of the second drive rod is connected to a second slide plate, and the other ends of the first drive rod and the second drive rod are respectively connected to a drive component; the drive component is adapted to drive the first drive rod and the second drive rod to move synchronously in opposite directions, so that the first slide plate moves relative to the fixed plate, the second slide plate moves relative to the first slide plate, and the first slide plate and the second slide plate move in the same direction.

[0013] Beneficial Effects: The retractable emergency steering column device provided in this embodiment achieves opposite movements of the first and second drive rods through synchronous drive of the drive component. However, since the drive component is fixed on the first sliding plate and the position of the fixed plate remains stationary, both the first and second sliding plates undergo relative displacement in the same direction relative to the fixed plate. This allows for synchronous movement of the multi-layered sliding structure through the same drive component, resulting in rapid lifting and lowering speeds to meet the needs of rapid lifting and lowering in emergency situations. Furthermore, the three-stage sliding design reduces the space occupied when the device is retracted, making the overall structure more compact and facilitating the rational use of vehicle interior space. In addition, the three-stage sliding design allows for a greater stroke, enabling the retractable emergency steering column device to have a wider adjustment range when deployed, adapting to the operating habits of drivers of different heights.

[0014] In one alternative embodiment, the driving element includes a motor, the first driving rod includes a first lead screw, and the second driving rod includes a second lead screw;

[0015] The motor is suitable for driving the transmission mechanism to move, and the transmission mechanism is suitable for simultaneously engaging with the first lead screw and the second lead screw to drive the first lead screw and the second lead screw to move synchronously and in opposite directions relative to the motor.

[0016] In one alternative implementation, the first drive rod and the second drive rod are arranged in parallel.

[0017] Beneficial effects: By arranging the first and second drive rods in parallel, the consistency and stability of the motion trajectory are ensured, mechanical wear is reduced, and the service life of the device is extended. The parallel arrangement also simplifies the design of the transmission mechanism, reduces manufacturing costs, and improves the overall system reliability and response speed. Furthermore, the parallel arrangement allows the device to maintain precise synchronization even at high speeds, effectively avoiding jamming or deviations caused by asynchronous movement, further enhancing the stability and safety of the device.

[0018] In one optional embodiment, the fixing plate is provided with a first connecting arm, and one end of the first driving rod is provided with a first driving rod fixing part, which is connected to the first connecting arm.

[0019] The second slide is provided with a second connecting arm, and a second driving rod fixing part is provided at one end of the second driving rod, which is connected to the second connecting arm.

[0020] Beneficial effects: By setting up a first connecting arm and a second connecting arm, a stable connection between the drive rod and the slide plate is ensured, enhancing the rigidity and durability of the overall structure. With pre-reserved installation positions, rapid installation and fixing can be achieved through bolts, clips, or welding, improving the assembly efficiency and ease of maintenance of the device.

[0021] In one alternative embodiment, the fixing plate is provided with a first dovetail groove, and the first sliding plate is provided with a first dovetail block that cooperates with the first dovetail groove. The first dovetail block is adapted to be embedded in the first dovetail groove and slide relative to the first dovetail groove.

[0022] The first slide plate has a second dovetail groove, and the second slide plate has a second dovetail block that cooperates with the second dovetail groove. The second dovetail block is adapted to be embedded in the second dovetail groove and slide relative to the second dovetail groove.

[0023] Beneficial effects: By adopting a dovetail-groove sliding structure, the stability and precision of the skateboard movement are improved, while effectively ensuring force distribution and preventing the first skateboard from detaching from the fixed board or the second skateboard from the first skateboard, thus meeting the force requirements for strong steering wheel rotation.

[0024] In one alternative implementation, the steering wheel connector is provided with a connection key adapted for detachable connection with the steering wheel.

[0025] Beneficial effects: The steering wheel and the connecting key can be connected by a plug-in joint, enabling quick installation and removal. After the steering wheel and the connecting key are connected, a quick-locking mechanism ensures a secure connection and prevents accidental detachment. When the steering wheel is not in use, the quick-locking mechanism can be unlocked, making it easy to remove the steering wheel for easy storage.

[0026] In one alternative implementation, it further includes an angle sensor disposed on the steering wheel connector for real-time monitoring of the steering wheel angle.

[0027] Beneficial effect: The angle sensor transmits the rotation angle signal to the control module, and the control module drives the wheel to rotate at the corresponding angle.

[0028] In one alternative embodiment, the system further includes a damper disposed on the steering wheel connector for adjusting the damping coefficient of the steering wheel.

[0029] Beneficial effects: By setting up a damper, a smooth steering feel can be provided, solving the problem of poor steering wheel control caused by the lack of ground friction and low column friction; making the steering wheel force closer to that of a real vehicle.

[0030] Secondly, this utility model also provides a vehicle, comprising:

[0031] Vehicle body;

[0032] And a retractable emergency steering column device, as described above, installed on the vehicle body.

[0033] The steering wheel is detachably connected to the retractable emergency steering column.

When the vehicle malfunctions or requires manual driving intervention, the steering column can be quickly and easily pulled out and the steering wheel installed. The operation is simple and convenient, greatly shortening the time to switch from autonomous driving mode to manual driving mode and improving the vehicle's safety and operability in emergency situations.

Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0052] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0053] The following is combined with Figures 1 to 7 The following describes embodiments of the present invention.

[0054] According to an embodiment of the present invention, a concealable emergency steering column device is provided, comprising:

[0055] Fixed plate 5 is suitable for fixed connection with external structure;

[0056] The first sliding plate 6 is slidably connected to the fixed plate 5, and the first sliding plate 6 is provided with a drive component fixing bracket 61;

[0057] The second slide plate 7 is slidably connected to the first slide plate 6 and is provided with a connector fixing bracket 71;

[0058] Drive component 2 is mounted on drive component mounting bracket 61;

[0059] Steering wheel connector 1, suitable for connecting a steering wheel; steering wheel connector 1 is mounted on connector mounting bracket 71;

[0060] The first drive rod 3 and the second drive rod 4 are connected, with one end of the first drive rod 3 connected to the fixed plate 5 and one end of the second drive rod 4 connected to the second slide plate 7. The other ends of the first drive rod 3 and the second drive rod 4 are respectively connected to the drive member 2. The drive member 2 is adapted to drive the first drive rod 3 and the second drive rod 4 to move synchronously in opposite directions, so that the first slide plate 6 moves relative to the fixed plate 5 and the second slide plate 7 moves relative to the first slide plate 6, and the first slide plate 6 and the second slide plate 7 move in the same direction.

[0061] The fixed plate 5 serves as the basic support structure for the retractable emergency steering column device, and all other moving parts are adapted to move relative to the fixed plate 5. The fixed plate 5 is provided with at least one mounting base 51, and the external structure includes an instrument crossbeam. The mounting base 51 is adapted to be fixedly connected to the instrument crossbeam.

[0062] Specifically, in this embodiment, the fixing plate 5 is provided with four mounting seats 51, located at its four corners, to ensure the stability and uniform force distribution of the fixing plate 5. The mounting seats 51 have holes, through which bolts or screws can be passed to securely connect to the instrument beam, ensuring a firm installation.

[0063] The first sliding plate 6 is suitable for sliding relative to the fixed plate 5, while the second sliding plate 7 is suitable for sliding relative to the first sliding plate 6, forming a multi-layer sliding structure. Both sets of sliding structures are driven by the same set of driving components 2 to ensure synchronization and coordination.

[0064] The drive component 2 is mounted on the drive component fixing bracket 61 of the first slide plate 6. The first drive rod 3 and the second drive rod 4 are respectively connected to the fixing plate 5 and the second slide plate 7. Specifically, one end of the first drive rod 3 is connected to the fixing plate 5, one end of the second drive rod 4 is connected to the second slide plate 7, and the other ends of the first drive rod 3 and the second drive rod 4 are respectively connected to the drive component 2. When the drive component 2 is working, it can drive the first drive rod 3 and the second drive rod 4 to move synchronously in opposite directions, thereby causing the first slide plate 6 to move relative to the fixing plate 5, and at the same time, the second slide plate 7 to move relative to the first slide plate 6.

[0065] The retractable emergency steering column device provided in this embodiment of the invention achieves opposite movements of the first drive rod 3 and the second drive rod 4 through synchronous driving of the drive component 2. However, since the drive component 2 is fixed on the first sliding plate 6 and the position of the fixed plate 5 remains stationary, both the first sliding plate 6 and the second sliding plate 7 are relatively displaced in the same direction relative to the fixed plate 5. Thus, the synchronous movement of the multi-layer sliding structure is achieved through the same drive component 2, resulting in fast lifting and lowering speeds to meet the rapid lifting and lowering needs in emergency situations. Furthermore, through the three-stage sliding mechanism, the device occupies less space when retracted, making the overall structure more compact and facilitating the rational utilization of vehicle interior space.

[0066] Furthermore, the three-stage sliding mechanism allows for a greater range of travel, enabling the retractable emergency steering column to have a wider adjustment range when deployed, adapting to the operating habits of drivers of different heights.

[0067] The drive component 2 can be driven by electricity or hydraulically, and the speed and force of movement can be adjusted according to actual needs.

[0068] In practical applications, such as when switching from manual driving mode to autonomous driving mode, the drive unit 2 receives a signal and drives the first drive lever 3 and the second drive lever 4 to move synchronously in opposite directions. This causes the first sliding plate 6 to retract relative to the fixed plate 5, and the second sliding plate 7 to retract synchronously relative to the first sliding plate 6. The entire device quickly retracts, achieving the concealment of the retractable emergency steering column device and maximizing interior space. Similarly, in an emergency requiring a switch from autonomous driving mode to manual driving mode, the drive unit 2 receives a signal and drives the first drive lever 3 and the second drive lever 4 to move synchronously in opposite directions. This causes the first sliding plate 6 to extend relative to the fixed plate 5, and the second sliding plate 7 to extend synchronously relative to the first sliding plate 6. The entire device quickly deploys, ensuring the driver can promptly take control of the vehicle and improving driving safety.

[0069] Combination Figure 4 As shown, the drive component fixing bracket 61 of the first slide plate 6 can be connected to the drive component 2 by bolts or welding. The drive component 2 can be installed on one side of the first slide plate 6, preferably without interfering with the movement of other components, to ensure a compact structure and flexible operation.

[0070] Combination Figure 6 As shown, the connector fixing bracket 71 of the second skateboard 7 is also connected to the steering wheel connector 1 by bolt connection or welding.

[0071] In some embodiments, the driving element 2 includes a motor, the first driving rod 3 includes a first lead screw, and the second driving rod 4 includes a second lead screw;

[0072] The motor is suitable for driving the transmission mechanism to move, and the transmission mechanism is suitable for simultaneously engaging with the first lead screw and the second lead screw to drive the first lead screw and the second lead screw to move synchronously and in opposite directions relative to the motor.

[0073] When the driving component 2 is a motor, and both the first driving rod 3 and the second driving rod 4 are lead screws, the transmission mechanism can specifically be a gear, a ball screw pair, a synchronous belt, or a chain, etc. These transmission schemes are all common transmission methods in the prior art, and those skilled in the art can flexibly choose according to actual application requirements. Structural details will not be elaborated here. After the motor starts, the transmission mechanism precisely controls the synchronous and opposite movements of the first and second lead screws, thereby causing the first sliding plate 6 to move relative to the fixed plate 5, and simultaneously, the second sliding plate 7 to move relative to the first sliding plate 6.

[0074] In some embodiments, the first drive rod 3 and the second drive rod 4 are arranged in parallel.

[0075] By arranging the first drive rod 3 and the second drive rod 4 in parallel, the consistency and stability of the motion trajectory are ensured, mechanical wear is reduced, and the service life of the device is extended. The parallel arrangement also simplifies the design of the transmission mechanism, reduces manufacturing costs, and improves the overall system reliability and response speed. Furthermore, the parallel arrangement allows the device to maintain precise synchronization even at high speeds, effectively avoiding jamming or deviations caused by asynchronous movement, further enhancing the stability and safety of the device.

[0076] In some embodiments, the fixing plate 5 is provided with a first connecting arm 52, and one end of the first driving rod 3 is provided with a first driving rod fixing part 31, which is connected to the first connecting arm 52.

[0077] The second slide plate 7 is provided with a second connecting arm 72, and one end of the second drive rod 4 is provided with a second drive rod fixing part 41, which is connected to the second connecting arm 72.

[0078] By setting up the first connecting arm 52 and the second connecting arm 72, a stable connection between the drive rod and the slide plate is ensured, enhancing the rigidity and durability of the overall structure. With pre-reserved installation positions, rapid installation and fixing can be achieved through bolts, clips, or welding, improving the assembly efficiency and ease of maintenance of the device.

[0079] In addition, the first connecting arm 52 extends outward from the outside of the fixed plate 5, and the second connecting arm 72 also extends outward from the outside of the second sliding plate 7, so as to facilitate observation and adjustment of the connection status, ensure a firm and reliable connection, and avoid interference with the movement of other components.

[0080] In some embodiments, the fixing plate 5 is provided with a first dovetail groove 53, and the first sliding plate 6 is provided with a first dovetail block 63 that cooperates with the first dovetail groove 53. The first dovetail block 63 is adapted to be embedded in the first dovetail groove 53 and slide relative to the first dovetail groove 53.

[0081] The first slide plate 6 has a second dovetail groove 62, and the second slide plate 7 has a second dovetail block 73 that cooperates with the second dovetail groove 62. The second dovetail block 73 is adapted to be embedded in the second dovetail groove 62 and slide relative to the second dovetail groove 62.

[0082] By adopting a dovetail-groove sliding structure, the stability and precision of the skateboard movement are improved, while effectively ensuring force distribution and preventing the first skateboard 6 from detaching from the fixed plate 5 or the second skateboard 7 from the first skateboard 6, thus meeting the force requirements for strong steering wheel rotation.

[0083] As a variation, the relative sliding mechanism between the fixed plate 5 and the first sliding plate 6 can also employ other types of guide rail structures, such as V-shaped guide rails or roller guide rails. Similarly, the relative sliding mechanism between the first sliding plate 6 and the second sliding plate 7 can also employ a similar guide rail structure to improve motion smoothness and precision. The selection of different guide rail structures can be rationally set according to specific application scenarios and load requirements to ensure that the device can operate stably and efficiently under various working conditions.

[0084] In some embodiments, the steering wheel connector 1 is provided with a connection key 11, which is adapted to be detachably connected to the steering wheel.

[0085] The steering wheel and the connecting key 11 can be connected by a plug-in joint, enabling quick installation and removal. After the steering wheel and connecting key 11 are connected, a quick-locking mechanism ensures a secure connection and prevents accidental detachment. When the steering wheel is not in use, the quick-locking mechanism can be unlocked for easy removal and storage. The specific structure of the quick-locking mechanism can include various designs such as snap-on, knob, magnetic, or spring locks, selected according to actual usage requirements. These solutions are all common quick-locking methods in the prior art and are not difficult for those skilled in the art to implement; therefore, they will not be elaborated further.

[0086] Additionally, the connection key 11 can be equipped with positioning holes that correspond to the positioning pins on the steering wheel, ensuring precise alignment during installation.

[0087] Combination Figure 6 As shown, the steering wheel connector 1 may specifically include an outer tube 12 and an inner tube 13, wherein the outer tube 12 is sleeved on the outside of the inner tube 13, and the connecting key 11 is set at one end of the inner tube 13, so that the inner tube 13 rotates relative to the outer tube 12 under the action of the steering wheel rotation, thereby realizing the flexible steering function of the steering wheel.

[0088] In this embodiment, the connector fixing bracket 71 of the second slide plate 7 can be fixedly connected to the outer tube 12, thereby ensuring that the outer tube 12 will not rotate. Figure 6 As shown, there can be multiple connector mounting brackets 71, which can be tightly connected to the outer tube 12 by bolts.

[0089] In this embodiment, a steer-by-wire system can be used as the receiving and processing unit for steering wheel rotation signals. The steer-by-wire system precisely controls the steering actuator through electronic signals, eliminating the need for mechanical transmission connections, thus making it easier to raise and lower the concealed emergency steering column device.

[0090] In some embodiments, the system further includes an angle sensor 8, which is disposed on the steering wheel connector 1 and is used to monitor the steering wheel angle in real time.

[0091] The angle sensor 8 can be fixed on the outer tube 12 and monitor the rotation angle of the inner tube 13 relative to the outer tube 12, thereby transmitting the rotation angle signal to the control module, and the control module drives the wheel to rotate at the corresponding angle.

[0092] In some embodiments, the system further includes a damper 9, which is disposed on the steering wheel connector 1 and is used to adjust the damping coefficient of the steering wheel.

[0093] By setting up damper 9, a smooth steering feel can be provided, solving the problem of poor steering wheel control caused by the lack of ground friction and low column friction; making the steering wheel force close to that of a real vehicle.

[0094] The top of the steering column body is equipped with a connection interface for connecting the steering wheel. The connection interface integrates a torque sensor and an angle sensor, which can monitor the driver's steering input force and angle in real time and transmit the data to the vehicle's electronic control system.

[0095] According to an embodiment of the present invention, another aspect provides a vehicle, comprising:

[0096] Vehicle body;

[0097] And a retractable emergency steering column device, as described above, installed on the vehicle body.

[0098] The steering wheel is detachably connected to the retractable emergency steering column.

[0099] The vehicle provided by the embodiments of this utility model has a steering column that can be completely hidden in a specific location inside the vehicle in autonomous driving mode, effectively freeing up interior space and providing more possibilities for interior layout design, such as transforming the driving area into a rest area or office area.

[0100] When the vehicle malfunctions or requires manual driving intervention, the steering column can be quickly and easily pulled out and the steering wheel installed. The operation is simple and convenient, greatly shortening the time to switch from autonomous driving mode to manual driving mode and improving the vehicle's safety and operability in emergency situations.

[0101] In some embodiments, the vehicle body includes an interior floor or a dashboard;

[0102] A storage cavity is formed under the interior floor or inside the dashboard to accommodate a retractable emergency steering column device;

[0103] The interior floor or dashboard has an opening that communicates with the storage cavity, and the concealable emergency steering column device is suitable for passing through the opening.

[0104] The vehicle body also includes a cover plate, which is movably disposed at the opening.

[0105] In this embodiment, the cover can be connected to an electric opening and closing mechanism, thereby achieving automatic opening and closing upon receiving an opening and closing signal from the vehicle control system. When it is necessary to hide the steering column, the cover automatically closes, keeping the interior space neat and aesthetically pleasing; when it is necessary to pull out the steering column, the cover automatically opens.

[0106] Obviously, the above embodiments are merely examples for clear illustration and are not intended to limit the implementation. Although embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and all such modifications and variations fall within the scope defined by the present invention.
