Description

Technical Field

[0001] The present application relates to the technical field of steering wheels, and in particular to a steering wheel, a steering system and a vehicle. Background Art

[0002] Existing car steering wheels are divided into full-spoke and half-width steering wheels. Full-width steering wheels eliminate the need for drivers to change their driving habits, provide more realistic driving feedback, and make it easier for drivers to perceive the vehicle's driving status. For those seeking a more intense driving experience, full-width steering wheels offer better control and stability, making the driving process more comfortable and safe. Half-width steering wheels provide more legroom and better visibility, but their design only includes an upper or lower semicircular section, which may cause instability during sharp turns or emergency maneuvers.

[0003] It can be seen that the full-width steering wheel and the half-width steering wheel each have advantages and disadvantages. However, the steering wheel driver of the existing vehicle cannot change the shape of the steering wheel according to driving habits or driving environment. Utility Model Content

[0006] Based on the steering wheel of the embodiment of the present application, the driving assembly drives the telescopic rim to switch between a first position and a second position along the radial direction of the steering wheel. When the telescopic rim is in the first position, it forms a half-width form with the fixed rim. When the telescopic rim is in the second position, it forms a full-width form with the fixed rim, thereby realizing the switching of the steering wheel between the full-width form and the half-width form. The driver can choose the full-width form or the half-width form according to personal road conditions, preferences, etc., which increases the user's choices while enriching the driving experience.

[0007] In some embodiments of the present application, the drive assembly includes a motor and a turntable, the motor is installed on the wheel hub; the turntable is transmission-connected to the motor, the turntable is provided with a slide rail, the slide rail is extended along the circumference of the steering wheel, and one end of the slide rail is arranged close to the center of the turntable, and the other end is arranged close to the edge of the turntable, and the telescopic wheel rim is slidingly connected to the groove wall of the slide rail.

[0008] Based on the above embodiment, the motor drives the turntable to rotate, and the slide rail arranged on the turntable rotates with the turntable. Since one end of the slide rail is arranged close to the center of the turntable and the other end is arranged close to the edge of the turntable, when the slide rail rotates with the turntable, it pushes the telescopic wheel rim to move radially in the steering wheel.

DETAILED DESCRIPTION

[0029] In order to make the purpose, technical solutions and advantages of this application more clearly understood, the present application is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not intended to limit this application.

[0030] Existing car steering wheels are divided into full-spoke and half-width steering wheels. Full-width steering wheels eliminate the need for drivers to change their driving habits, provide more realistic driving feedback, and make it easier for drivers to perceive the vehicle's driving status. For those seeking a more intense driving experience, full-width steering wheels offer better control and stability, making the driving process more comfortable and safe. Half-width steering wheels provide more legroom and better visibility, but their design only includes an upper or lower semicircular section, which may cause instability during sharp turns or emergency maneuvers.

[0031] It can be seen that the full-width steering wheel and the half-width steering wheel each have advantages and disadvantages. However, the steering wheel driver of the existing vehicle cannot change the shape of the steering wheel according to driving habits or driving environment.

[0032] To solve the above technical problems, please refer to Figures 1 to 2As shown, in the first aspect, an embodiment of the present application discloses a steering wheel, which includes a body component 10 and a drive component. The body component 10 includes a hub 11, a fixed rim 12 and a telescopic rim 13. The fixed rim 12 is mounted on the hub 11; the telescopic rim 13 is slidably mounted on the hub 11 along the radial direction a of the steering wheel. The telescopic rim 13 has a first position and a second position in the radial direction of the steering wheel. When the telescopic rim 13 is in the first position, it forms a half-width form with the fixed rim 12. When the telescopic rim 13 is in the second position, it forms a full-width form with the fixed rim 12; the drive component is mounted on the hub 11, and the telescopic rim 13 is transmission-connected to the drive component. The drive component can drive the telescopic rim to switch between the first position and the second position along the radial direction a of the steering wheel.

[0033] A full-width steering wheel is one with no cuts. Its rim has a complete circle or a quasi-circular outline, providing a larger hand support area. A half-width steering wheel's rim typically occupies only half or less of the steering wheel compared to a full-width wheel.

[0034] The fixed rim 12 is a fixed rim of the steering wheel. When the telescopic rim 13 is in the first position, the fixed rim 12 constitutes a half-width steering wheel. It can be understood that there are two fixed rims 12. The two fixed rims 12 are arranged opposite to each other and are distributed along the width direction of the vehicle when the steering wheel is not rotated, so that the user can hold the two fixed rims 12 with both hands.

[0035] The telescopic rim 13 is capable of moving along the radial direction a of the steering wheel. It can be understood that there are two telescopic rims 13. When the two telescopic rims 13 are in the second position, the telescopic rims 13 fill the space between the two adjacent fixed rims 12, so that the telescopic rims 13 and the fixed rims 12 constitute a full-width steering wheel. The two telescopic rims 13 are arranged opposite to each other and when the steering wheel is not rotated, the two fixed rims 12 are distributed along the length direction of the vehicle.

[0036] The wheel hub 11 is the central part of the steering wheel. The wheel hub 11 is used to accommodate the airbag, drive components, wiring harness, etc., and the wheel hub 11 is used to connect the drive shaft of the steering system.

[0037] Based on the steering wheel of the embodiment of the present application, the driving assembly drives the telescopic rim 13 to switch between a first position and a second position along the radial direction a of the steering wheel. When the telescopic rim 13 is in the first position, it forms a half-width form with the fixed rim 12. When the telescopic rim 13 is in the second position, it forms a full-width form with the fixed rim 12, thereby realizing the switching of the steering wheel between the full-width form and the half-width form, allowing the driver to choose the full-width form or the half-width form according to personal road conditions, preferences, etc., thereby increasing the user's selectivity while enriching the driving experience.

[0038] In some embodiments of the present application, the drive assembly includes a motor and a turntable 20, the motor is installed on the wheel hub 11; the turntable 20 is transmission-connected to the motor, and the turntable 20 is provided with a slide rail 21, which extends along the circumference of the steering wheel, and one end of the slide rail 21 is arranged near the center of the turntable 20, and the other end is arranged near the edge of the turntable 20, and the telescopic wheel rim is slidingly connected to the groove wall of the slide rail 21.

[0039] The motor drives the turntable 20 to rotate, and the slide rail 21 provided on the turntable 20 rotates together with the turntable 20. Since one end of the slide rail 21 is arranged near the center of the turntable 20 and the other end is arranged near the edge of the turntable 20, when the slide rail 21 rotates with the turntable 20, it pushes the telescopic wheel rim to move in the radial direction a of the steering wheel.

[0040] In the embodiment of the present application, there is no limitation on the type of motor, as long as the motor can drive the turntable 20 to rotate forward and reverse. However, the size of the motor should be limited to ensure that the motor should be fixed in the wheel hub 11 and does not affect the layout of the airbag.

[0041] A slide rail 21 is provided on the turntable 20, and the telescopic rim 13 is driven to move by the slide rail 21. In the embodiment of the present application, the shape of the turntable 20 is not limited, as long as the area of the turntable 20 is sufficient to arrange the slide rail 21; considering that the number of the telescopic rims 13 is two, the number of the slide rails 21 should also be configured as two, and each slide rail 21 is slidably connected to the corresponding telescopic rim 13; to ensure that the slide rail 21 can drive the telescopic rim 13 to switch between the first position and the second position, the length of the slide rail 21 along the radial direction of the steering wheel is equal to or greater than the moving distance of the telescopic rim 13 from the first position to the second position.

[0042] In some embodiments of the present application, a slide groove is provided on the telescopic wheel rim 13, and the slide rail 21 is in the slide groove and is slidably connected to the groove wall of the slide groove. In this way, a slide groove is provided on the telescopic wheel rim 13, and the slide rail 21 is in the slide groove and is slidably connected to the groove wall of the slide groove. When the slide rail 21 rotates with the turntable 20, the various parts of the slide rail 21 slide through the slide groove in turn, and external force is applied to the groove wall of the slide groove to push the telescopic wheel rim 13 to move along the radial direction a of the steering wheel.

[0043] In other embodiments of the present application, a slide groove may be provided on the turntable 20, and a slider may be provided on the telescopic rim 13. The slider is located in the slide groove and is slidably connected to the groove wall of the slide groove.

[0044] In some embodiments of the present application, the wheel hub 11 includes a main body 111 and a guide portion. The main body 111 is used to connect the drive shaft, and the motor, turntable 20 and fixed rim 12 are all installed on the main body 111; the guide portion is installed on the main body 111, and the guide portion is slidingly connected to the telescopic rim 13. In this way, the wheel hub 11 is provided with a guide portion to limit the moving direction of the telescopic rim 13, that is, the telescopic rim 13 is limited by the guide portion to move only along the radial direction a of the steering wheel.

[0045] In the embodiment of the present application, the shapes of the main body 111 and the guide portion are not limited.

[0046] In some embodiments of the present application, the telescopic rim 13 includes a rim portion 131 and a sliding portion; the sliding portion extends along the radial direction a of the steering wheel, and the sliding portion is slidably connected to the guide portion. In this way, the sliding portion and the guide portion are slidably connected to realize the sliding connection between the telescopic rim 13 and the wheel hub 11. When the telescopic rim 13 is in the second position, the rim portion 131 and the fixed rim 12 constitute a full-width steering wheel. When the telescopic rim 13 is in the first position, the rim portion 131 and the fixed rim 12 constitute a half-width steering wheel.

[0047] In some embodiments of the present application, the guide portion is configured as a guide cylinder 112, and the sliding portion is configured as a sliding rod 132, which is disposed within the guide cylinder 112. The sliding rod 132 is disposed within the guide cylinder 112 to achieve a sliding connection between the telescopic rim 13 and the wheel hub 11 along the radial direction of the steering wheel. At the same time, the guide cylinder 112 limits the sliding rod 132 to move only along the radial direction a of the steering wheel.

[0048] Given that there are two retractable rims 13, and that they are arranged along the length of the vehicle when the steering wheel is not turned, in this embodiment of the present application, there are two guide cylinders 112, which are fixed to the circumference of the main body 111 and arranged opposite each other along the length of the vehicle. One end of the sliding rod 132 is connected to the rim 131, and the other end passes through the guide cylinder 112 and is slidably connected to the slide rail 21 located within the main body 111.

[0049] In some embodiments of the present application, a first limiting structure and a second limiting structure are provided on the sliding rod 132. When the telescopic rim 13 is in the first position, the first limiting structure abuts the end of the guide cylinder 112 away from the main body 111. When the telescopic rim 13 is in the second position, the second limiting structure abuts the end of the guide cylinder 112 close to the main body 111.

[0050] When the telescopic rim 13 is in the first position, the first limiting structure abuts the end of the guide cylinder 112 away from the main body 111. At this time, the first limiting structure limits the sliding rod 132 from sliding further relative to the guide cylinder 112. When the telescopic rim 13 is in the second position, the second limiting structure abuts the end of the guide cylinder 112 close to the main body 111. The second limiting structure limits the sliding rod 132 from sliding further relative to the guide cylinder 112.

[0051] In some embodiments of the present application, the sliding rod 132 includes a first main body section, a sliding section and a second main body section connected in sequence, the radial length of the sliding section is smaller than the radial length of the first main body section, so as to form a first shoulder 1321 at the end face where the first main body section is connected to the sliding section, the radial length of the sliding section is smaller than the radial length of the second main body section, so as to form a second shoulder 1322 at the end face where the second main body section is connected to the sliding section, the first limiting structure is the first shoulder 1321, and the second limiting structure is the second shoulder 1322.

[0052] By setting the sliding rod 132 as a diameter-reducing rod to form a first shaft shoulder 1321 and a second shaft shoulder 1322 on the sliding rod 132 , the first shaft shoulder 1321 and the second shaft shoulder 1322 are reliably limited.

[0053] In the second aspect, the embodiment of the present application provides a steering system, which includes a detection module, a control module and a steering wheel as described above; the detection module is used to detect vehicle speed information, steering wheel angle information and steering wheel torque information; the control module is connected to the detection module and the drive component in communication

[0054] Based on the steering system of the embodiment of the present application, the detection module detects vehicle speed information, steering wheel angle information and steering wheel torque information, and the control module receives the vehicle speed information, steering wheel angle information and steering wheel torque information to control the drive component and adjust the shape of the steering wheel.

[0055] The detection module in the embodiment of the present application includes a vehicle speed detector, a rotation angle meter, and a torque detector, wherein the rotation angle meter and the torque detector can be integrated into one.

[0056] In the embodiment of the present application, the controller may be an ECU (Electronic Control Unit) of the entire vehicle, or a separate controller may be provided.

[0057] An embodiment of the present application further provides a control method, which is applied to the above-mentioned steering system, for example, to a control module of the steering system, and includes:

[0058] Obtain switching instructions, vehicle speed information, steering wheel angle information, and steering wheel torque information;

[0059] When the vehicle speed information is less than the preset speed within a certain period of time in the full-width state, the steering wheel angle = 0°, and the steering wheel torque is less than or equal to the preset torque, a first switching instruction is sent to the drive component, and the first switching instruction is used to enable the drive component to drive the telescopic wheel rim 13 to move from the second position to the first position; the switching instruction includes the first switching instruction.

[0060] In the half-width state, the vehicle speed information is greater than or equal to the preset speed within a certain period of time, the steering wheel angle = 0°, and the steering wheel torque is less than or equal to the preset torque. A second switching instruction is sent to the drive component, and the second switching instruction is used to enable the drive component to drive the telescopic wheel rim 13 from the first position to the second position; the switching instruction includes the second switching instruction.

[0061] The preset speed and preset torque may be set to different values according to different vehicle models. In some embodiments of the present application, the preset speed is 50 km / h and the preset torque is 0.2 N·m.
