Description

Technical Field

[0001] This application relates to the field of vehicle manufacturing technology, and in particular to a vehicle steering system and a vehicle. Background Technology

[0002] When a vehicle turns, the driver typically operates the steering wheel, which, through the steering shaft, steering tie rod, and steering knuckle, drives the wheels to rotate, thus achieving vehicle steering. Regardless of whether the vehicle is traveling at a high or low speed, the steering ratio remains a fixed value, making it difficult to adjust the steering ratio according to vehicle speed, resulting in insufficient driving flexibility and stability. Utility Model Content

[0003] This application provides a vehicle steering system and a vehicle to solve the technical problems of insufficient driving operation flexibility and stability in existing vehicles.

[0004] According to one aspect of this application, a vehicle steering system is provided, comprising: a steering wheel mechanism; a control module electrically connected to the steering wheel mechanism; and a steering mechanism including a drive member and a connecting assembly, wherein the drive member is electrically connected to the control module, and the connecting assembly is connected to the output end of the drive member, wherein the drive member is configured to be controlled by the control module and drive the wheels to steer through the connecting assembly.

[0005] The vehicle steering system provided in this application includes a steering wheel mechanism, a control module, and a steering mechanism. When steering is performed, the driver rotates the steering wheel mechanism. The control module receives the rotation angle signal from the steering wheel mechanism and controls the drive components to move. The drive components drive the connecting components to move, thereby moving the wheels to achieve steering. Therefore, the vehicle steering system of this application, by receiving the rotation angle signal and controlling the drive components through the control module, can adjust the steering ratio in real time according to the vehicle speed. This allows for a smaller gear ratio at lower speeds, improving driving maneuverability, and a larger gear ratio at higher speeds, improving operational stability.

[0006] In a further preferred embodiment, there are multiple steering mechanisms connected in parallel to the control module, and each steering mechanism is used to steer different wheels.

[0007] In this design, the vehicle steering system includes multiple steering mechanisms, each responsible for steering different wheels. Furthermore, all steering mechanisms are connected in parallel to the control module, allowing the control module to independently control the steering of each wheel. This makes the vehicle's steering more agile and improves its steering performance.

[0008] In a further preferred embodiment, the connecting assembly is configured such that, under the driving action of the driving member, the wheel rotates and steers about the center line of the output end of the driving member as the axis of rotation.

[0009] In this scheme, the wheel is rotated around the center line of the output end of the drive component to steer. This facilitates precise control of the wheel's steering angle and makes it easier to determine the relative positions of the drive component and connecting assembly with the wheel, thus facilitating the installation of the drive component and connecting assembly.

[0010] In a further preferred embodiment, the connecting assembly includes a bogie and a suspension. The bogie is provided with mounting holes and is connected to the output end of the drive unit through the mounting holes. The suspension is connected to the bogie and is used to connect to the wheels.

[0011] In this design, the connecting assembly includes a bogie and a suspension. The drive unit is connected to the bogie and the wheels are steered via the bogie and suspension. Therefore, the bogie and suspension enhance the assembly flexibility of the connecting assembly, improving its adaptability to different vehicle models.

[0012] In a further preferred embodiment, the mounting hole extends along the Z-direction.

[0013] In this design, by extending the mounting hole along the Z-axis (i.e., along the vehicle's height), the output end of the drive component, after being installed within the mounting hole, also extends along the vehicle's height. This allows the drive component to rotate the wheels about the vehicle's height axis, facilitating vehicle steering control.

[0014] In a further preferred embodiment, the drive member includes a body and an outer edge, the body having the output end and for extending into the mounting hole, and the outer edge connecting to and protruding from the body and for connecting to the periphery of the mounting hole.

[0015] In this design, an outer edge protrudes from the main body of the driving component. When the main body is inserted into the mounting hole, it can be connected to the outer periphery of the mounting hole through the outer edge, thereby installing the main body in the mounting hole. The installation operation is convenient and stable.

[0016] In a further preferred embodiment, the connecting assembly further includes a shock absorber, one end of which is connected to the bogie and the other end of which is connected to the wheel.

[0017] In this design, shock absorbers are installed between the bogie and the wheels. These shock absorbers reduce the bumps caused by the vehicle driving on uneven roads, thereby improving the driving and riding experience.

[0018] In a further preferred embodiment, the steering mechanism further includes a braking assembly connected to the connecting assembly and used to connect with the wheel to brake the wheel.

[0019] In this solution, when the vehicle needs to slow down, such as in an emergency, the braking components can brake the wheels to bring the vehicle to a stop in time, thereby avoiding safety accidents and reducing safety risks.

[0020] In a further preferred embodiment, the steering wheel mechanism includes a steering wheel, a steering column, and an angle sensor. The steering column is connected to the steering wheel, and the angle sensor is connected to the steering column. The angle sensor is electrically connected to the control module and is used to transmit the rotation angle signal of the steering column to the control module.

[0021] In this design, when steering, the driver can manually turn the steering wheel, which in turn rotates the steering column. An angle sensor detects the steering angle of the steering column and transmits the angle signal to the control module. The control module then receives the angle signal and controls the drive components to move the wheels, thus achieving steering. This design makes steering convenient, efficient, and highly safe.

[0022] According to another aspect of this application, a vehicle is provided, including the vehicle steering system described in any of the above claims.

[0023] The vehicle in this application includes a vehicle steering system. Based on the structural design of the vehicle steering system itself, when the vehicle is turning, it can receive the rotation angle signal of the steering wheel mechanism through the control module and control the action of the drive components. It can then adjust the steering transmission ratio in real time according to the vehicle speed to improve the driving flexibility and operational stability of the vehicle.

[0024] In summary, the vehicle steering system and vehicle provided in this application have at least the following beneficial effects:

[0025] The vehicle provided in this application includes a vehicle steering system, which comprises a steering wheel mechanism, a control module, and a steering mechanism. When steering is performed, the driver rotates the steering wheel mechanism. The control module receives the rotation angle signal from the steering wheel mechanism and controls the drive components to move. The drive components then drive the connecting components to move, thereby moving the wheels to achieve steering. Therefore, the vehicle steering system of this embodiment, by receiving the rotation angle signal and controlling the drive components through the control module, can adjust the steering ratio in real time according to the vehicle speed. Since the steering ratio is adjustable, it can appropriately reduce the steering ratio when the vehicle is turning at low speeds and large angles to reduce the turning radius and improve steering maneuverability, while appropriately increasing the steering ratio when the vehicle is turning at higher speeds to improve steering stability.

[0045] It should be noted that, for ease of understanding of the technical solution of this application, this document describes the provided vehicle steering system 10 and the vehicle in detail using a spatial rectangular coordinate system XYZ. Specifically, when the vehicle is normally traveling on the road and the vehicle steering system 10 is mounted on the vehicle body 30, the X-direction refers to the length direction of the vehicle, the Y-direction refers to the width direction of the vehicle, and the Z-direction refers to the height direction of the vehicle. In this document, when describing directions, the X, Y, and Z directions should all refer to the directions defined above and should not be understood as any other direction, which will not be elaborated upon further.

[0046] The vehicle provided according to the embodiments of this application can be a fuel-powered vehicle, a natural gas-powered vehicle, or a new energy vehicle. New energy vehicles can be pure electric vehicles, hybrid electric vehicles, or range-extended electric vehicles, etc. Specifically, the vehicle of this application includes a vehicle steering system 10. Due to the adoption of the vehicle steering system 10, based on its own structural design, the vehicle can receive the rotation angle signal from the steering wheel mechanism 100 through the control module 200 and control the drive component 310 to move when steering. This allows for real-time adjustment of the steering ratio according to the vehicle speed, thereby improving the vehicle's driving flexibility and operational stability.

[0047] Please refer to Figures 1 to 6The vehicle steering system 10 provided in this application embodiment includes a steering wheel mechanism 100, a control module 200, and a steering mechanism 300.

[0048] The steering wheel mechanism 100 is installed inside the vehicle body 30 and is used for the driver to perform steering operations.

[0049] The control module 200 is electrically connected to the steering wheel mechanism 100, for example, via a wiring harness, to obtain the driver's steering direction. Specifically, when the vehicle needs to turn, the driver can turn the steering wheel 110. At this time, the control module 200 can obtain the rotation angle signal of the steering wheel mechanism 100 to determine whether the driver intends to turn left or right, so as to control the vehicle's steering.

[0050] The steering mechanism 300 includes a drive element 310 and a connecting assembly 320. The drive element 310 is electrically connected to the control module 200, and the connecting assembly 320 is connected to the output end of the drive element 310. The drive element 310 is configured to be controlled by the control module 200 and drive the wheels 20 to steer via the connecting assembly 320. For example, the drive element 310 can be a motor, which is electrically connected to the control module 200. The control module 200 can drive the output shaft of the motor to rotate, thereby driving the wheels 20 to steer via the connecting assembly 320.

[0051] With the above structural design, when a steering operation is performed, the driver rotates the steering wheel mechanism 100. The control module 200 receives the rotation angle signal of the steering wheel mechanism 100 and controls the drive component 310 to move. The drive component 310 drives the connecting assembly 320 to move, thereby driving the wheel 20 to move and achieve steering. Thus, the vehicle steering system 10 of this embodiment, by receiving the rotation angle signal and controlling the drive component 310 through the control module 200, can adjust the steering ratio in real time according to the vehicle speed. The steering ratio refers to the ratio of the steering angle of the steering wheel 110 to the steering angle of the wheel 20. Since the steering ratio is adjustable, it can appropriately reduce the steering ratio when the vehicle is at a low speed and a large angle of steering to reduce the turning radius and improve the vehicle's steering maneuverability, while appropriately increasing the steering ratio when the vehicle is at a high speed and a large angle of steering to improve the vehicle's steering stability.

[0052] As a further preferred embodiment, based on the above-mentioned solution, the specific embodiments of this application may also include one or more of the following additions or combinations.

[0053] Reference Figure 2In some optional embodiments, the control module 200 includes a controller 210, a control circuit 220, a power supply 230, and a power supply circuit 240. The controller 210 is electrically connected to the steering wheel mechanism 100 and is electrically connected to the drive members 310 corresponding to the left and right wheels 20 of the vehicle via the control circuit 220. The drive members 310 are electrically connected to the power supply 230 via the power supply circuit 240. The controller 210 can receive rotation angle signals from the steering wheel mechanism 100 and output signals to control the drive members 310 to move, thereby turning the wheels 20. The power supply 230 is used to supply power to the drive members 310.

[0054] In some optional embodiments, there are multiple steering mechanisms 300 connected in parallel to the control module 200. Each steering mechanism 300 is used to steer a different wheel 20. Specifically, the number of steering mechanisms 300 can correspond to the number of wheels 20, with each steering mechanism 300 steer a specific wheel 20. For example, for a common four-wheeled car, four corresponding steering mechanisms 300 can be provided. All steering mechanisms 300 are connected in parallel to the control module 200, allowing the control module 200 to independently control the steering of each wheel 20, thus making the vehicle's steering more flexible and improving its steering performance.

[0055] Furthermore, the control module 200 can control multiple wheels 20 to turn at different angles. For example, the control module 200 can control the drive components 310 corresponding to the left and right wheels 20 to perform independent steering operations, that is, the steering movements of the left and right wheels 20 are completely decoupled. The control module 200 can simultaneously control the left and right wheels 20 to achieve different speeds and different steering angles, and can also adapt to the steering requirements of high-level autonomous driving.

[0056] Therefore, the vehicle steering system of this embodiment can dynamically and in real time adjust the steering angle relationship between the left and right wheels 20 of the vehicle, i.e., the Ackerman ratio, where the Ackerman ratio is the ratio of the steering angles of the inner and outer wheels 20 when the vehicle is turning. Specifically, when the vehicle is turning, with a fixed inner wheel steering angle, increasing the outer wheel steering angle can reduce the Ackerman ratio, thus reducing the understeer of the vehicle; with a fixed inner wheel steering angle, decreasing the outer wheel steering angle can increase the Ackerman ratio, thus increasing the understeer of the vehicle. In low-speed steering and parking conditions, reducing the Ackerman ratio improves steering efficiency and reduces the turning radius; in high-speed steering, increasing the Ackerman ratio improves understeer and enhances steering safety performance. Additionally, a special steering function mode for all four wheels of the vehicle can also be implemented, for example, referring to... Figure 3 State (1) shows the turning angle of wheel 20 when the vehicle is moving straight; state (2) shows the 90° turning angle of wheel 20 when the vehicle is moving laterally; state (3) shows the positive toe-in steering of the front wheels and the negative toe-in steering of the rear wheels to achieve the vehicle's stationary turning mode.

[0057] In some alternative embodiments, the connecting component 320 is configured to cause the wheel 20 to rotate around the center line of the output end of the drive member 310 under the driving action of the drive member 310.

[0058] For example, refer to Figure 4 The diagram shows the steering direction of the steering wheel mechanism 100 and the wheel 20 indicated by arrows. In the illustrated state, the centerline of the output end of the drive member 310 is the steering kingpin of the wheel 20. By controlling the wheel 20 to rotate and steer around the centerline of the output end of the drive member 310, it is convenient to accurately control the steering angle of the wheel 20, and it is also convenient to determine the relative position of the drive member 310 and the connecting assembly 320 with the wheel 20, thereby facilitating the installation of the drive member 310 and the connecting assembly 320.

[0059] In some optional embodiments, the connecting assembly 320 includes a bogie 321 and a suspension 322. The bogie 321 has a mounting hole 321a and is connected to the output end of the drive member 310 through the mounting hole 321a. The suspension 322 is connected to the bogie 321 and is used to connect to the wheel 20. The connecting assembly 320 is configured to include a bogie 321 and a suspension 322, with the drive member 310 connected to the bogie 321 and driving the wheel 20 to steer via the bogie 321 and suspension 322. Therefore, the assembly flexibility of the connecting assembly 320 can be improved by using the bogie 321 and suspension 322, thereby enhancing its adaptability to different vehicle models.

[0060] For example, refer to Figure 5 and Figure 6 The bogie 321 has a mounting hole 321a on its top, and its bottom is connected to the vehicle body 30. The drive unit 310 is connected to the vehicle body 30 on its top, and its bottom is connected to the bogie 321 through the mounting hole 321a. The suspension 322 consists of multiple crossbeams and vertical beams arranged at different angles to improve assembly flexibility. During vehicle steering, the steering wheel mechanism 100 rotates a certain angle, and the control module 200 obtains the rotation angle signal and controls the drive unit 310 to drive the bogie 321 to rotate. The bogie 321 then drives the wheels 20 to rotate through the suspension 322, thus achieving vehicle steering.

[0061] In some optional embodiments, the mounting hole 321a extends along the Z-direction. By extending the mounting hole 321a along the Z-direction, that is, extending the mounting hole 321a along the height direction of the vehicle body 30, the output end of the drive member 310 also extends along the height direction of the vehicle body 30 after the drive member 310 is placed in the mounting hole 321a. Thus, the drive member 310 can drive the wheel 20 to rotate about the height direction of the vehicle body 30 as an axis, which is beneficial for controlling the vehicle steering.

[0062] In some optional embodiments, the drive member 310 includes a body 311 and an outer edge 312. The body 311 has an output end for extending into the mounting hole 321a, and the outer edge 312 is connected to and protrudes from the body 311 for connecting with the outer periphery of the mounting hole 321a. The outer edge 312 protrudes from the body 311 of the drive member 310. When the body 311 is inserted into the mounting hole 321a, the outer edge 312 can connect with the outer periphery of the mounting hole 321a, thereby installing the body 311 within the mounting hole 321a. This installation operation is convenient and secure.

[0063] For example, refer to Figure 6 The drive component 310 has a generally cylindrical body 311 and outer edge 312, with the outer edge 312 protruding beyond the outer periphery of the body 311. The drive component 310 is located on top of the bogie 321 and is coaxially mounted with the mounting hole 321a at the center of the top of the bogie 321. Specifically, the body 311 of the drive component 310 is connected to the outer periphery of the mounting hole 321a, i.e., the top of the bogie 321, using several evenly distributed bolts; the top of the outer edge 312 of the drive component 310 is also connected to the vehicle body 30 through several evenly distributed bolts.

[0064] In some optional embodiments, the connection assembly 320 further includes a shock absorber 323, one end of which is connected to the bogie 321 and the other end of which is connected to the wheel 20. Exemplarily, the shock absorber 323 may be a spring. By providing the shock absorber 323 between the bogie 321 and the wheel 20, the vibration caused by the vehicle traveling on uneven road surfaces can be reduced, thereby improving the driving and riding experience.

[0065] In some optional embodiments, the steering mechanism 300 further includes a braking assembly 330, which is connected to the connecting assembly 320 and used to connect to the wheel 20 to brake the wheel 20. When the vehicle needs to decelerate, for example in an emergency, the braking assembly 330 can brake the wheel 20 to bring the vehicle to a timely stop, thereby avoiding safety accidents and reducing safety risks.

[0066] For example, refer to Figure 5 The braking assembly 330 can be integrated with the hub motor, which drives the wheels 20 to rotate, thereby driving the entire vehicle. Furthermore, the braking assembly 330 is connected to the bogie 321 via the suspension 322, and the drive unit 310 is connected to the bogie 321 via the suspension 322, making the structure of the braking assembly 330, suspension 322, bogie 321, and bogie 321 compact.

[0067] In some optional embodiments, the steering wheel mechanism 100 includes a steering wheel 110, a steering column 120, and an angle sensor. The steering column 120 is connected to the steering wheel 110, and the angle sensor is connected to the steering column 120. The angle sensor is electrically connected to the control module 200 and is used to transmit the rotation angle signal of the steering column 120 to the control module 200.

[0068] Specifically, when performing a steering operation, the driver can manually turn the steering wheel 110, which in turn drives the steering column 120 to rotate. At this time, the angle sensor can detect the steering angle of the steering column 120 and transmit the rotation angle signal to the control module 200. Then, the control module 200 receives the rotation angle signal and controls the drive component 310 to move, thereby driving the wheels 20 to achieve steering. The steering operation is convenient, efficient, and highly safe.

[0069] Through the above design, the vehicle steering system 10 provided in this application embodiment can realize advanced driver assistance functions, such as controlling the left and right wheels 20 to simultaneously steer with positive toe-in during braking to improve straight-line braking stability; if the vehicle yaws during braking, the steering angle of each of the four wheels 20 can be adjusted individually to eliminate or reduce the yaw, thereby realizing or improving the ESCE Electronic Stability Controller function; when the vehicle is turning with a large understeer or oversteer tendency, the steering performance of the vehicle can be optimized by dynamically adjusting the steering angle of the outer wheels; the toe-in angle of each wheel 20 can be controlled individually according to the straight-ahead state of the vehicle to improve the vehicle steering performance.

[0070] Although embodiments of this application have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting this application. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of this application.
