Technical Field

[0001] The present application relates to the field of vehicle technology, and in particular to a steering wheel assembly, a steering device and a vehicle. Background Art

[0002] Vehicles have become a common means of transportation in our daily lives. People have increasingly stringent requirements for vehicle safety, power, economy, and comfort. The steering wheel is the center of control in a vehicle and the component with which the driver spends the most time while driving. Therefore, it significantly impacts the driver's experience of the vehicle. Furthermore, the proper fit of the steering wheel significantly impacts both driving safety and comfort.

[0003] In one scenario, drivers can experience slippage and other safety hazards due to improper steering wheel operation, such as insufficient grip strength, distracted attention, or fatigue. In another scenario, many drivers, due to varying driving habits, prefer to drive one-handed. Alternatively, after extended periods of driving, many drivers may seek a degree of physical relaxation through one-handed driving. However, when turning the steering wheel with one hand, insufficient friction between the hand and the steering wheel can easily lead to slippage, compromising driving safety.

[0004] In situations such as the one mentioned above, the industry has not yet developed a comprehensive technical solution to overcome the related defects in terms of how to improve the safety of the driver's steering wheel operation. Summary of the Invention

[0010] Furthermore, the sensing control unit is further used to obtain the rotation direction information of the steering wheel body; when the sensing control unit senses the holding position of the sensing target object, it enables the driving unit to drive the raising of the protrusion adjacent to the sensing target object in the rotation direction.

[0011] Furthermore, the steering wheel body further includes an anti-slip member. The anti-slip member is disposed on a surface of the protrusion away from the grip portion. The anti-slip member is integrally formed with the protrusion or fixedly connected to the protrusion.

[0012] Furthermore, the sensing control unit senses the holding position of the sensing target, so as to enable the driving unit to drive the raising of the protrusion in contact with the sensing target.

[0025] It can be seen from the above embodiments that the protrusions of the steering wheel assembly of the present application can form an uneven surface on the gripping portion, which is beneficial to increase the friction between the driver's hand and the gripping portion, so that the driver's hand can maintain an unchanged relative position with the steering wheel body, avoiding slipping between the hand and the gripping portion, and improving driving safety.

[0034] refer to Figures 1 to 3In a first aspect, the present application provides a steering wheel assembly 100, comprising a steering wheel body 1, a drive unit 2 and a sensing control unit 3. The steering wheel body 1 comprises a gripping portion 11 and a protrusion assembly 12 arranged on the gripping portion 11. The gripping portion 11 is provided with a gripping surface. The protrusion assembly 12 comprises a plurality of protrusions 121 arranged with the gripping surface. The drive unit 2 is connected to the protrusion assembly 12 for driving the lifting and lowering movement of the protrusions 121. The sensing control unit 3 is electrically connected to the drive unit 2 for detecting the gripping position of the sensing target so as to enable the drive unit 2 to drive the lifting and lowering movement of the corresponding protrusions 121. In one embodiment, the sensing target is the palm of the driver who operates the steering wheel. Optionally, in another embodiment, the sensing target is a part such as the driver's fingers. The following description will be made using the palm as an example of the sensing target.

[0035] The raising and lowering of the raised member 121 creates an uneven surface on the grip portion 11, thereby increasing the friction between the driver's hand and the grip portion 11, allowing the driver's hand to maintain a constant relative position with the steering wheel body 1, preventing the hand and the grip portion 11 from slipping, which could lead to driving hazards. Furthermore, the provision of the raised member 12 allows the steering wheel body 1 to exert a certain amount of force on the driver's palm when operating the steering wheel body 1 with one hand. Therefore, the steering wheel assembly 100 is suitable for drivers who are accustomed to one-handed driving, and ensures a certain degree of safety for one-handed driving, without the need for additional components such as a power ball.

[0036] For the convenience of explanation, the embodiment shown in the drawings defines a first direction X, a second direction Y and a third direction Z which are perpendicular to each other. Figure 1 In the embodiment shown, the gripping surface is a plane where the first direction X and the second direction Y are located. However, this is for illustration and not limitation. In other embodiments, the gripping surface may also be a plane where the first direction X and the third direction Z are located, and this application is not limited thereto.

[0037] There are many ways for the sensing control unit 3 to sense the palm. Figure 3 As shown, in some embodiments, the sensing control unit 3 includes a touch sensing element 31. The touch sensing element 31 is arranged on the surface of the protrusion 121 away from the grip portion 11. When the driver's palm touches the steering wheel body 1, the palm can be placed on the touch sensing element 31. The touch sensing element 31 can be a capacitive sensor. When the driver places the palm on the capacitive sensor, the capacitance of the sensing control unit 3 increases, and therefore its voltage also increases. By sensing the change in voltage, it is possible to detect whether the palm is placed on the grip portion 11 and on which protrusions 121 the palm is placed, that is, the contact position between the palm and the grip portion 11.

[0038] The touch sensing element 31 can also be a temperature sensor. The temperature sensor can detect the temperature of the palm, and therefore can also detect whether the palm is placed on the grip portion 11, and the specific position of the palm. Due to exposure to the sun and other reasons, some parts of the grip portion 11 may be hot in the summer even if the driver does not place his palm there (for example, Figure 2 The temperature of the protrusion 121 also reaches a temperature close to that of the human body. To avoid false triggering, the sensing control unit 3 can be provided with a calibration procedure, such as obtaining the ambient temperature as a reference value for temperature determination.

[0039] In some embodiments, the sensing control unit 3 includes a pressure sensor connected to the protrusion assembly 12. The pressure sensor is used to detect palm contact force. The pressure sensor can be connected to all protrusions 121, or the pressure sensor can be connected to each protrusion 121 in a one-to-one or one-to-many relationship, which is not limited in this application. When the driver's hand grasps the grip portion 11 or places it on the grip surface, the hand applies pressure to the steering wheel body 1. At this time, the pressure sensor can detect which protrusions 121 are under pressure, thereby determining the placement of the hand.

[0040] The sensing control unit 3 can be configured as a combination of sensors. For example, the sensing control unit 3 can include both a capacitive sensor and a pressure sensor, or both a pressure sensor and a temperature sensor. This combination of multiple sensing methods can improve the accuracy of palm position sensing by the steering wheel assembly 100 and prevent false triggering of the protrusion 121.

[0041] When the sensing control unit 3 senses the position of the palm, the drive unit 2 drives the corresponding protrusion 121 to protrude. In some embodiments, the sensing control unit 3 is further used to obtain the rotation direction of the steering wheel body 1. When the sensing control unit 3 senses the gripping position of the palm, the drive unit 2 is enabled to drive the protrusion 121 adjacent to the palm in the rotation direction to rise. For example, when the driver's right hand is placed on the right side of the steering wheel body 1, and the driver's right hand rotates the steering wheel body 1 counterclockwise, if the friction between the palm and the gripping portion 11 is insufficient, the palm has a tendency to move to the left. At this time, the drive unit 2 drives the protrusion 121 adjacent to the palm on the left side to rise. The left side of the palm can rest against the protrusion 121 to prevent the palm from slipping to the left, providing a more stable fixation for the palm.

[0042] The cooperation between the driving unit 2 and the sensing control unit 3 can be carried out in real time. Figure 2In the illustrated perspective, when the driver's right hand is placed at the 3 o'clock position on the steering wheel body 1 and the steering wheel body 1 is rotated counterclockwise, the raised member 121 on the left side of the right hand rises. As the driver's right hand continues to rotate the steering wheel body 1 and reaches the 9 o'clock position and continues to rotate the steering wheel body 1 counterclockwise, the raised member 121 on the right side of the right hand rises, while the raised member 121 on the left side can descend. With this arrangement, the steering wheel assembly 100 can provide the driver with real-time driving support and enhance the driver's driving experience.

[0043] By configuring the raised member 121 to rise when needed and lower when not needed, the steering wheel assembly 100 improves its overall aesthetics and streamlined appearance. For example, the raised member 121 is configured so that when it remains lowered, the surface away from the grip portion 11 smoothly transitions into the curve of the grip portion 11. This ensures that the raised member 121, when not in operation, does not negatively impact the steering wheel assembly 100's appearance or the gripping experience of the grip portion 11.

[0044] Of course, in other embodiments, the raised member 12 can remain raised. When the driver turns, the raised member 121 corresponding to the palm position descends. In this way, the raised members 121 on both the left and right sides of the palm can contact the palm, providing support, eliminating the need to determine the rotation direction of the steering wheel body 1.

[0045] In some embodiments, the steering wheel body 1 further includes an anti-slip member. The anti-slip member is disposed on the surface of the raised member 121 away from the grip portion 11. The provision of the anti-slip member can increase the friction between the palm and the steering wheel body 1, preventing the palm and the grip portion 11 from slipping. The anti-slip member can be integrally formed with the raised member 121, i.e., an anti-slip pattern or the like can be machined on the surface of the raised member 121. Alternatively, the anti-slip member can be a component made of a common anti-slip material such as a rubber member, and fixedly connected to the raised member 121 by bonding or other means, and this application is not limited thereto.

[0046] In an embodiment in which an anti-slip member is provided, the sensing control unit 3 can sense the gripping position of the palm, so as to enable the driving unit 2 to drive the raising of the raised member 121 in contact with the palm. Since the raised member 121 at the palm position is raised, the contact tightness between the anti-slip member and the palm is increased, and thus the anti-slip effect provided by the anti-slip member for the palm is also improved. In this way, the palm does not need to be supported by the raised member 121, and the rotation angle and amplitude of the palm are more flexible when the steering wheel body 1 is rotated. In addition, the raised member 121 below the palm can provide the driver with a real-time sensing experience, improving the driver's driving experience and sense of technology.

[0047] In an embodiment where the sensing control unit 3 is a pressure sensor, the sensing control unit 3 enables the drive unit 2 based on the force feedback of the pressure sensor to control the protrusion height of the protrusion 121. In other words, the pressure sensor is capable of detecting the contact force between the palm and the grip portion 11. When the contact force is different, the drive unit 2 controls the protrusion height of the protrusion 121 to be different. For example, when the contact force is small, it can be determined that the driver's grip on the steering wheel body 1 is small at this time, and the possibility of slipping is high, so the protrusion height of the protrusion 121 can be relatively high. When the contact force is large, the driver's grip is large and the possibility of slipping is relatively small, so the protrusion height can be relatively low. Through such an arrangement, the steering wheel assembly 100 can provide targeted driving support for drivers with different gripping habits in different situations.

[0048] The driving unit 2 drives the protruding member 121 to move in the lifting direction. Figure 1 In the embodiment shown, the lifting direction is the third direction Z, that is, perpendicular to the gripping plane. In other embodiments, the lifting direction can form an angle of, for example, 80 degrees or 90 degrees with the gripping surface, and this application is not limited thereto.

[0049] refer to Figure 3 The sensing control unit 3 is electrically connected to the main control unit 4 and the power supply 5. The number of sensing control units 3 may be multiple. In some embodiments, there is a one-to-many relationship between the sensing control units 3 and the protrusions 121. After the sensing control unit 3 senses contact between the palm and the grip 11, it sends a signal to the main control unit 4, which controls the corresponding protrusions 121 to protrude in response to the signal.

[0050] In other embodiments, the sensing control units 3 correspond one-to-one with the protrusions 121. The protrusions 121 include a first wiring harness 1211 and a second wiring harness 1212. The first wiring harness 1211 connects the protrusions 121 and the sensing control units 3 corresponding to the protrusions 121. The second wiring harness 1212 connects the protrusions 121 and the sensing control units 3 corresponding to the adjacent protrusions 121.

[0051] by Figure 3 Taking the illustrated embodiment as an example, the protrusion 121 on the left is referred to as the first protrusion, and the protrusion 121 on the right is referred to as the second protrusion. The sensing control unit 3 on the left is referred to as the first sensing unit, the sensing control unit 3 in the middle is referred to as the second sensing unit, and the sensing control unit 3 on the right is referred to as the third sensing unit. The first protrusion corresponds to the first sensing unit. The second protrusion corresponds to the second sensing unit. The first wiring harness 1211 of the first protrusion is connected to the first sensing unit, and the second wiring harness 1212 is connected to the second sensing unit. The first wiring harness 1211 of the second protrusion is connected to the second sensing unit, and the second wiring harness 1212 is connected to the third sensing unit.

[0052] When the palm is placed on the first protrusion, both the first sensing unit and the second sensing unit can receive signals. If the second protrusion does not send a signal to the second sensing unit, the steering wheel assembly 100 can determine that the palm is not placed on the second protrusion.

[0053] With this arrangement, the signal linkage between the sensing control units 3 does not need to be implemented through the main control unit 4, so the steering wheel assembly 100 senses the position of the driver's palm more accurately and drives the protrusion 121 more quickly.

[0054] The drive unit 2 may be a hydraulic component. One end of the hydraulic component is provided on the gripping portion 11, and the other end is connected to the protruding component 121. The protruding component 121 is raised and lowered by hydraulic drive, and the response speed is fast, and the hydraulic component can also stably resist the force applied to the steering wheel body 1 by the driver's palm. Alternatively, the drive unit 2 includes a motor, a gear driven by the motor, and a rack connected to the protruding component 121. The rack cooperates with the gear. Gear transmission can provide a high-precision transmission effect, which is beneficial for controlling the protruding height of the protruding component 121. In addition, the gear and rack are small in size and light in weight, which is beneficial for assembly in the limited space of the steering wheel assembly 100.

[0055] like Figure 3 As shown, the protrusion 121 is connected to the grip portion 11, and the drive unit 2 lifts the protrusion 121. Therefore, when the drive unit 2 lifts the protrusion 121, a gap exists between the grip portion 11 and the protrusion 121. Liquid and dust can enter the interior of the steering wheel body 1 through the gap, thereby causing damage to the drive unit 2 and the sensing control unit 3. Therefore, in some embodiments, the steering wheel body 1 further includes a flexible seal 13. The flexible seal 13 connects the protrusion 121 and the grip portion 11. The retractability of the flexible seal 13 meets the protrusion requirement of the protrusion 121. Even if the driver touches the gap between the protrusion 121 and the grip portion 11, the flexibility of the flexible seal 13 can provide a soft tactile feeling to avoid scratches.

[0056] Based on the steering wheel assembly 100 described in each of the above embodiments, the present application further provides a steering device. The steering device includes the steering wheel assembly 100 and a steering shaft connected to the steering wheel assembly 100. The steering wheel assembly 100 is provided with a protrusion 121, which can increase the friction between the driver's hand and the grip 11, allowing the driver's hand to maintain a fixed relative position with the steering wheel body 1, preventing the hand and the grip 11 from slipping, and thus improving the safety performance of the steering device.

[0057] Based on the steering device, the present application further provides a vehicle including the steering device. The steering wheel assembly 100 of the steering device includes a protrusion assembly 12. The provision of the protrusion assembly 12 enables the steering wheel body 1 to exert a certain force on the palm when the driver operates the steering wheel body 1 with one hand, so that the vehicle is suitable for drivers who are accustomed to one-handed driving. The protrusion assembly 12 can also increase the friction between the driver's hand and the grip portion 11, so that the driver's hand can maintain a constant relative position with the steering wheel body 1, avoiding slipping between the hand and the grip portion 11, which is beneficial to improving the safety performance of the steering device.

[0058] In some embodiments, the vehicle includes an obstacle detection device electrically connected to the sensing control unit 3. When the obstacle detection device detects an obstacle signal and orientation outside the vehicle, the sensing control unit 3 enables the drive unit 2 to raise the protrusion 121 adjacent to the opposite side of the palm's orientation. It should be noted that the "opposite side" here should be understood as the direction in which the steering wheel body 1 needs to be rotated to avoid the obstacle. For example, if the obstacle is located in the front left of the vehicle, the vehicle needs to move toward the front right, meaning the driver needs to rotate the steering wheel body 1 clockwise. In this case, the protrusion 121 adjacent to the opposite side is the protrusion 121 adjacent to the palm in the clockwise direction. Similarly, if the obstacle is located in the front right of the vehicle, the vehicle needs to move toward the front left, meaning the driver needs to rotate the steering wheel body 1 counterclockwise. In this case, the protrusion 121 adjacent to the opposite side is the protrusion 121 adjacent to the palm in the counterclockwise direction.

[0059] For example, if the obstacle detection device detects an obstacle in front of the left side of the vehicle, the vehicle determines that the driver needs to urgently turn the steering wheel body 1 clockwise. Figure 2 If the hand is in the upper half circle shown, the palm will easily slip to the left, so the raised piece 121 on the left side of the palm rises. Figure 2 As shown in the lower semicircle, the palm is likely to slide to the right, and the raised piece 121 on the right side of the palm rises.

[0060] Through such a setting, the vehicle can pre-judge the possible operations of the driver, prepare for emergency turning in advance, and link the internal and external signals of the vehicle to activate the protrusion of the protrusion 121 in an emergency, helping the driver to better avoid danger and improve the driving safety of the vehicle.

[0061] The specific embodiments described herein are merely illustrative of the spirit of the present application. Those skilled in the art may make various modifications, additions, or substitute similar methods for the described specific embodiments without departing from the spirit of the present application or exceeding the scope defined by the appended claims.

[0062] The technical features of the above embodiments can be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
