The terminology used in the application's specification is for describing particular embodiments only and is not intended to be limiting of the application. The use of the terms "and / or" includes a combination of one or more of the associated listed items.

[0027] At present, a knob is often arranged in a vehicle interior, and different adjustment and control functions are realized through switching of different gears of the knob. Among them, the traditional knob mostly adopts a mechanical structure to realize gear shifting, and thus gives a certain use feedback to the user.

[0028] However, the traditional mechanical knob has a single hand feeling, and the gear and hand feeling of each knob are set at the factory and cannot be adjusted in use, which is very monotonous in operation and function strategy. Moreover, with the improvement of user requirements, such fixed hand feeling feedback has been difficult to meet the user's use demand, reducing the user's use experience.

[0029] Please refer to Figure 1 and Figure 2 To solve the problem that the hand feeling of the existing knob is relatively single, the application provides a knob device 100, which comprises a fixed seat 10, a rotating assembly 20, a first bearing 30, a second bearing 40, a friction piece 50, a first driving piece 60 and a second driving piece 70.

[0030] Please refer to Figure 2 The fixed seat 10 is provided with an assembly groove 101, the assembly groove 101 is provided with an opening 1011 at one end of the fixed seat 10 in the axial direction, the friction piece 50, the second bearing 40 and the first bearing 30 are sequentially installed in the assembly groove 101 through the opening 1011, the rotating assembly 20 is arranged at one end of the fixed seat 10 close to the opening 1011, and the rotating assembly 20 can rotate around the axis of the fixed seat 10 under the action of external force.

[0031] Further, one end of the first bearing 30 is connected to the rotating assembly 20 through a first elastic piece 31, and the other end is connected to the second bearing 40 through a second elastic piece 41, so that the rotating assembly 20 and the second bearing 40 can move relative to the first bearing 30 in the axial direction of the fixed seat 10. Moreover, when the rotating assembly 20 rotates in response to external force, the rotating assembly 20 can drive the first bearing 30 and the second bearing 40 to rotate synchronously through the first elastic piece 31 and the second elastic piece 41.

[0032] Specifically, when the rotating assembly 20 rotates, the rotating assembly 20 drives the first carrier 30 to rotate through the first elastic member 31, and in the process of rotation, the first carrier 30 drives the second carrier 40 to rotate through the second elastic member 41. During this period, the second driving member 70 can exert a force on the second carrier 40, and the second carrier 40 can move towards the friction member 50 under the drive of the second driving member 70 and exert a force on the friction member 50, so that the second carrier 40 and the friction member 50 can generate a friction force that hinders the circumferential movement of the second carrier 40 along the fixed seat 10. The friction force can be transmitted to the operator's hand, thereby generating a rotating hand feeling.

[0033] Further, when the first carrier 30 rotates by a preset angle, the first driving member 60 can exert a force on the rotating assembly 20 for a preset time, and the rotating assembly 20 can move towards the fixed seat 10 under the drive of the first driving member 60 and compress the first elastic member 31, so that the first elastic member 31 has a tendency to push the rotating assembly 20 to move towards the direction away from the fixed seat 10. That is, during the force exerted by the first driving member 60, the first elastic member 31 is compressed to generate elastic potential energy, and when the force exerted by the first driving member 60 is eliminated, the elastic potential energy of the first elastic member 31 is released and generates vibration, which is transmitted to the operator's hand through the rotating assembly 20, so that the operator can feel the vibration hand feeling.

[0034] The present application can give the operator a vibration hand feeling by setting the rotating assembly 20, the first elastic member 31, the first carrier 30 and the first driving member 60, and can give the operator a friction damping hand feeling by setting the second carrier 40, the friction member 50 and the second driving member 70. Through the combination of the two kinds of hand feelings, a periodic signal feedback is realized, thereby greatly improving the use experience of the operator. Moreover, the vibration hand feeling can be adjusted by the size of the force exerted by the first driving member 60, and the damping hand feeling can be adjusted by the size of the force exerted by the second driving member 70, thereby realizing the diversification of the hand feeling, being more flexible in use, and meeting the use requirements of different users.

[0035] Further, the second elastic member 41 connects the first carrier 30 and the second carrier 40, and the second carrier 40 can rotate with the rotation of the first carrier 30, thereby reducing the rotation difficulty of the second carrier 40, without the need to additionally set other structures for driving the second carrier 40 to rotate, thereby facilitating the arrangement of internal parts of the knob device 100 and improving the space utilization. In addition, the second elastic member 41 can also meet the need of the axial movement of the second carrier 40 along the fixed seat 10, so that the second carrier 40 can press the friction member 50 under the drive of the second driving member 70 and generate a damping hand feeling, thereby improving the use experience of the operator.

[0036] Specifically, when the second driving member 70 is not activated, the second bearing member 40 can be attached to the friction member 50, and the elastic force of the second elastic member 41 can be equal to the gravity of the second bearing member 40, so that, under the action of the elastic force of the second elastic member 41, there is no pressure between the second bearing member 40 and the friction member 50, thereby reducing the wear between the second bearing member 40 and the friction member 50. When the second driving member 70 is activated, the second bearing member 40 can directly apply pressure to the friction member 50 and generate a damping hand feel, thereby improving the response speed of the hand feel feedback.

[0037] Of course, in other embodiments, the second bearing member 40 can also be spaced apart from the friction member 50 or directly pressed against the friction member 50, etc., which can be reasonably arranged according to actual needs.

[0038] In an embodiment, the knob device 100 further comprises a processor (not shown in the figure), which is electrically connected with the first driving member 60 and the second driving member 70 respectively, to control the size of the force applied by the first driving member 60 and the second driving member 70 and the output time.

[0039] In use, the processor can control the pressure applied by the second bearing member 40 to the friction member 50 by controlling the size of the force applied by the second driving member 70, and the change of the pressure will cause the friction force acting on the second bearing member 40 to change accordingly, thereby playing a role in adjusting the hand feel. Similarly, the processor can adjust the vibration hand feel generated by the first elastic member 31 by controlling the size of the force applied by the first driving member 60.

[0040] Among them, the force applied by the processor to control the first driving member 60 and the second driving member 70 can be linearly changed, or it can be nonlinearly changed, which can be controlled by changing the software strategy of the processor, thereby further improving the diversity of hand feel settings. And different software strategies can also realize different mode combinations, so as to realize the integration of multiple functions on one knob device 100.

[0041] For example, the processor can control the knob device 100 to be used as a mode conversion switch, and take 90° as a hand feel period, and the operator generates a complete hand feel and realizes mode conversion every 90° of rotation. In addition, the processor can also control the knob device 100 to be used as an air conditioner controller, and take 30° as a rotation period to generate a complete hand feel. Of course, the processor can also be used for the control of other functions, which are not listed here.

[0042] And the above-mentioned functions can be displayed through the display screen 24 fixed on the rotating assembly 20, thereby facilitating the operator to observe more intuitively, so as to better operate the knob device 100.

[0043] In an embodiment, as shown inFigure 2 As shown, the first driving member 60 comprises a first magnetic attraction member 61 and a first metal member 62, the first magnetic attraction member 61 is fixedly arranged on the fixed seat 10, the first metal member 62 is fixedly arranged on the rotating assembly 20, and the first magnetic attraction member 61 is electrically connected with the angle sensor 90, when the angle sensor 90 detects that the first bearing member 30 rotates a preset angle, the first magnetic attraction member 61 can attract the first metal member 62 and drive the rotating assembly 20 to move towards the fixed seat 10.

[0044] Further, as shown in the embodiment, Figure 2 As shown, in an embodiment, the second driving member 70 comprises a second magnetic attraction member 71 and a second metal member 72, the second magnetic attraction member 71 is fixedly arranged on the inner wall of the assembly groove 101, the second metal member 72 is fixedly arranged on the second bearing member 40, and the second magnetic attraction member 71 is electrically connected with the angle sensor 90, when the angle sensor 90 detects that the first bearing member 30 starts to rotate, the second magnetic attraction member 71 can attract the second metal member 72 and drive the second bearing member 40 to move towards the friction member 50.

[0045] Specifically, the first magnetic attraction member 61 and the second magnetic attraction member 71 can be electromagnetic coils, thus facilitating control, the processor can control the suction force of the electromagnetic coil by controlling the current flowing into the electromagnetic coil, thereby adjusting the hand feeling of the knob device 100. Moreover, fixing the first magnetic attraction member 61 and the second magnetic attraction member 71 on the fixed seat 10 which does not rotate can further improve the reliability of the first driving member 60 and the second driving member 70 in use.

[0046] In other embodiments, the first driving member 60 can also be a linear motor, a voice coil motor or a piezoelectric ceramic. Similarly, the second driving member 70 can also be a linear motor, a voice coil motor or a piezoelectric ceramic. As long as the same effect can be achieved.

[0047] In an embodiment, the fixed seat 10 comprises a main body part 11 and an extension part 12, the extension part 12 extends along the axial direction of the fixed seat 10, and the main body part 11 and the extension part 12 surround to form the assembly groove 101. Among them, the first bearing member 30 and the second bearing member 40 are sleeved on the circumferential side of the extension part 12 to prevent the first bearing member 30 and the second bearing member 40 from moving radially along the fixed seat 10.

[0048] By setting the extension part 12, the installation of the first bearing member 30 and the second bearing member 40 is facilitated, and the radial movement of the first bearing member 30 and the second bearing member 40 when rotating can be prevented, thereby improving the rotation stability and cooperation precision of the first bearing member 30 and the second bearing member 40.

[0049] Further, in an embodiment, as shown in the embodiment, Figure 2As shown, the knob device 100 further comprises a bearing 32, which defines a first side wall 1012 of the wall of the assembly groove 101 away from the extension 12, and the outer wall of the first carrier 30 is rotationally connected to the first side wall 1012 through the bearing 32, and the bearing 32 can prevent the first carrier 30 from moving axially along the fixed seat 10.

[0050] It can be understood that the arrangement of the bearing 32 can not only limit the axial movement of the first carrier 30 along the fixed seat 10, but also will not hinder the rotation of the first carrier 30. Moreover, since the axial movement of the first carrier 30 along the fixed seat 10 is limited, it can be ensured that the two parts of the knob device 100 that generate the vibration feeling and the damping feeling will not interfere with each other. For example, when the second driving member 70 drives the second carrier 40 to move towards the friction member 50 to generate the damping feeling, the second elastic member 41 is stretched to generate an elastic force. If the axial movement of the first carrier 30 along the fixed seat 10 is not limited, the second elastic member 41 will in turn pull the first carrier 30, the first elastic member 31 and the rotating assembly 20 towards the friction member 50, so that the rotating assembly 20 vibrates. In this way, the control difficulty of the two kinds of feeling changes will be increased, and the rotation judgment of the operator will be affected. When the first driving member 60 drives the rotating assembly 20 to move towards the first carrier 30 to generate the vibration feeling, similar to the above principle, the friction member 50 will also be pressed, and the second carrier 40 and the friction member 50 will generate friction to form the feeling. Therefore, the arrangement of the bearing 32 can prevent the parts with different functions from interfering with each other, thereby reducing the control difficulty of the damping feeling and the vibration feeling, and improving the control accuracy.

[0051] Specifically, the bearing 32 can be a conventional ball bearing 32, thereby reducing the cost. The outer ring of the bearing 32 is fixedly connected to the first side wall 1012, and the inner ring of the bearing 32 is fixedly connected to the first carrier 30, and the relative rotation is realized through the balls arranged between the inner ring and the outer ring.

[0052] In an embodiment, the friction member 50 is fixedly arranged on the inner wall of the assembly groove 101. In this way, the rotation of the friction member 50 relative to the fixed seat 10 can be avoided, so that the fixed seat 10 is not worn. Moreover, since the friction member 50 is in a fixed state, the relative rotation between the second carrier 40 and the friction member 50 can form a stable frictional resistance, thereby facilitating the formation of the damping feeling.

[0053] Further, in an embodiment, as shown in Figure 2 The knob device 100 further comprises a force sensor 80, one end of the force sensor 80 is connected to the inner wall of the assembly groove 101, and the other end of the force sensor 80 is connected to the friction member 50, for detecting the force acting on the force sensor 80 by the second carrier 40 towards the friction member 50. The force sensor 80 is electrically connected to the processor.

[0054] Thus, by arranging the force sensor 80, the pressure of the second bearing member 40 on the friction member 50 can be accurately measured, and when the processor receives the pressure signal of the force sensor 80, the signal is transmitted to the second driving member 70 after processing and analysis, so that the force applied by the second driving member 70 to the second bearing member 40 can be more accurately controlled, and real-time control of the damping feel is realized.

[0055] Further, in an embodiment, the friction member 50 is a flexible element. Thus, the pressure received can be transmitted to the force sensor 80, and the force sensor 80 can be prevented from being damaged by collision, thereby improving the service life of the force sensor 80.

[0056] Specifically, the material of the friction member 50 is rubber, silicone or soft plastic, which is not listed here.

[0057] Further, in an embodiment, as shown in Figure 2 The force sensor 80 is embedded in the friction member 50. Thus, the force sensor 80 can better obtain the pressure transmitted by the friction member 50. Moreover, the force sensor 80 occupies less space and does not affect the installation of the friction member 50 and other components in the assembly groove 101, thereby improving the space utilization of the overall knob device 100.

[0058] In an embodiment, the knob device 100 further comprises an angle sensor 90, which is installed on the side of the fixed seat 10 away from the opening 1011, and the angle sensor 90 is arranged corresponding to the first bearing member 30 to detect the angle of rotation of the first bearing member 30 around the fixed seat 10. The angle sensor 90 is electrically connected to the processor.

[0059] By arranging the angle sensor 90, the rotation signal of the first bearing member 30 can be recognized, and when the processor receives the signal transmitted by the angle sensor 90, the first driving member 60 and the second driving member 70 can be controlled to apply forces of different sizes and times, thereby realizing different operation feels.

[0060] In an embodiment, as shown in Figure 2 The first elastic member 31 is a sheet spring, and the sheet spring used in the present application is basically in the form of a ring, which can be connected to the end surface of the first bearing member 30 along the circumference of the fixed seat 10, thereby improving the contact area between the sheet spring and the first bearing member 30 and greatly improving the connection strength and stability of the sheet spring and the first bearing member 30.

[0061] Further, in an embodiment, as shown in Figure 2As shown, the rotating assembly 20 comprises a rotating cap 21, a fixed plate 22 and a fastener 23, the rotating cap 21 is arranged on one end of the fixed seat 10 close to the opening 1011, one end of the first elastic member 31 is connected to the first bearing member 30, and the other end is clamped between the rotating cap 21 and the fixed plate 22, the fastener 23 is sequentially arranged through the fixed plate 22 and the first elastic member 31 and is connected with the rotating cap 21, so that the fixed connection of the first elastic member 31 and the rotating assembly 20 is realized.

[0062] Wherein, the rotating cap 21 is provided with anti-skid ribs 211 on the side, so as to facilitate the operation of the operator. The fixed plate 22 is used for fixing with other parts (such as the first metal member 62, etc.), so as to avoid affecting the structure of the rotating cap 21.

[0063] In other embodiments, the first elastic member 31 can also be a metal spring, a rubber spring or an air spring, as long as it can have the same effect of making the rotating assembly 20 and the first bearing member 30 move axially.

[0064] In an embodiment, as shown, Figure 2 The second elastic member 41 is a linear metal spring, which is simple in structure, easy to form and can reduce the cost of the knob device 100.

[0065] Further, the second elastic member 41 is a plurality of second elastic members 41, and the plurality of second elastic members 41 are uniformly and spacedly arranged along the circumference of the second bearing member 40, so as to improve the stress stability of the second bearing member 40. Wherein, the second bearing member 40 is provided with a receiving hole capable of accommodating the second elastic member 41, so as to reduce the occupation of the second elastic member 41 to the internal space of the knob device 100, and improve the space utilization of the knob device 100.

[0066] But not limited to this, in other embodiments, the second elastic member 41 can also be a sheet spring, a rubber spring or an air spring, as long as it can have the same effect of making the first bearing member 30 and the second bearing member 40 move axially.

[0067] The knob device 100 provided by the application is used, the operator rotates the rotating cap 21 of the rotating assembly 20, so that the rotating assembly 20 drives the first bearing member 30 to rotate through the first elastic member 31, and the first bearing member 30 drives the second bearing member 40 to rotate synchronously through the second elastic member 41 during rotation.

[0068] When the first carrier 30 rotates, the angle sensor 90 can identify the rotation signal of the first carrier 30 and transmit the signal to the processor, and the processor controls the second driving member 70 to start, under the driving of the second driving member 70, the second carrier 40 moves towards the direction close to the friction member 50 and exerts pressure on the friction member 50, so that the friction member 50 generates friction force to hinder the circumferential rotation of the second carrier 40, and thus generates damping hand feeling feedback to the operator's hand. Wherein, the pressure exerted by the second carrier 40 on the friction member 50 can be detected by the force sensor 80, and the force sensor 80 transmits the pressure signal to the processor, so as to more accurately control the pressure exerted by the second carrier 40 on the friction member 50, and realize the control adjustment of the damping hand feeling.

[0069] Further, the processor can set different preset angles according to different functional needs.
