Description

Technical Field

[0001] This application relates to the field of vehicle control equipment technology, and more particularly to a wireless control knob and a vehicle. Background Technology

[0002] The central control screen is a human-machine interface terminal set up inside the vehicle. Drivers can use the central control screen to perform visual operations of functions such as navigation, multimedia, air conditioning, vehicle settings and driving assistance. However, some functions, such as seat massage, are located in the multi-level menu of the central control screen. Operating them while driving will prolong the time the driver's eyes are off the road. Therefore, it is necessary to set up control knobs in the car for quick adjustment.

[0003] In related technologies, the control knob includes a housing and a cover. The cover is rotatably mounted on the housing and has an encoder. A circuit board is installed inside the housing, and the encoder is electrically connected to the circuit board. When the cover rotates, the encoder rotates synchronously and outputs an electrical pulse signal corresponding to the angle. After receiving the electrical pulse signal, the circuit board switches according to preset logic and issues control commands for the corresponding functions to realize the adjustment of vehicle functions.

[0004] However, when the vehicle is driving on a bumpy road or the driver accidentally touches the cover, the cover may rotate, which may trigger a function and interfere with normal driving, thus creating a safety hazard. Utility Model Content

[0005] This application provides a wireless control knob and vehicle to solve the technical problem in related technologies where control knobs trigger a certain function when the vehicle is driving on a bumpy road or when the driver accidentally touches it, interfering with normal driving and posing a safety hazard.

[0006] In a first aspect, embodiments of this application provide a wireless control knob, including:

[0007] case;

[0008] A cover body, which is rotatably connected to the housing and moves axially along the housing when pressed;

[0009] A reset element is disposed on the housing and is used to drive the cover to reset after the cover is released.

[0011] In some embodiments, the housing is provided with a plurality of first buckles in the circumferential direction, and a moving space is formed between the first buckles and the bottom wall of the housing. The cover is provided with a second buckle in the circumferential direction. When the cover is pressed, the second buckle disengages from the plurality of first buckles and moves within the moving space. After the cover is released, the second buckle engages with the plurality of first buckles through the reset member.

[0012] In some embodiments, the reset member includes a plurality of elastic rods and a plurality of abutment blocks. At least one end of the elastic rods is connected to the housing. The abutment blocks are disposed on the corresponding elastic rods and are used to abut or disengage from the cover when the cover is pressed or released.

[0013] In some embodiments, the edge of the housing is provided with a plurality of grooves along the circumference of the housing, one end of the elastic rod is connected to one of the two sides opposite to the groove, and a deformation space is formed between the elastic rod and the bottom wall of the groove, the deformation space being used for the elastic rod to move into when the cover is pressed.

[0016] In some embodiments, the system further includes a wireless module and a power supply unit. The wireless module is electrically connected to the control module and is used to wirelessly connect the control module and the vehicle. The power supply unit is disposed within the housing and is electrically connected to the control module, and is used to provide power to the control module.

[0017] In some embodiments, the housing includes a base, a middle frame, and a cover plate. The middle frame is disposed within the base, the control module is disposed within the middle frame, the cover is rotatably connected to the middle frame, and the cover plate is engaged or disengaged from the side of the base away from the cover plate. A receiving space for accommodating the power supply component is formed between the control module and the cover plate.

[0018] In some embodiments, a plurality of toggle beads are elastically connected to one of the outer side wall of the housing and the inner side wall of the cover, and a plurality of stop grooves are provided on the other of the outer side wall of the housing and the inner side wall of the cover, the stop grooves being used to allow the toggle beads to move in or out when the cover rotates.

[0045] The accompanying drawings illustrate specific embodiments of this application, which will be described in more detail below. These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concept of this application to those skilled in the art through reference to particular embodiments. Detailed Implementation

[0046] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0047] In related technologies, the control knob includes a housing and a cover. The cover is coaxially mounted on the top of the housing via a miniature bearing. An incremental encoder is connected to the back of the cover. A main control circuit board is fixed inside the housing. When the cover rotates, the encoder rotates synchronously and outputs an electrical pulse signal corresponding to the angle. After receiving the electrical pulse signal, the main control circuit board switches according to preset logic and issues control commands for the corresponding functions to realize the adjustment of vehicle functions.

[0048] However, when the vehicle is driving on bumpy roads, the vibrations of the steering wheel and center console area will be transmitted to the cover through the housing; the driver's or passenger's cuff or key fob may also accidentally touch the edge of the cover. Since the encoder can generate pulses with a tiny angular displacement, the system will immediately regard it as a valid input, causing a function to be suddenly activated, such as suddenly turning the air conditioning fan to the maximum, causing a sudden change in temperature, adjusting the volume, causing the volume to spike instantly, or unexpectedly switching the driving mode. Such false triggers not only distract the driver, but may also bring potential safety risks due to sudden changes in the vehicle's thermal management state or acoustic environment.

[0049] The technical solution of this application and how the technical solution of this application solves the above-mentioned technical problems are described in detail below with specific embodiments. These specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments. The embodiments of this application will now be described with reference to the accompanying drawings.

[0050] Combination Figures 1 to 4 This application provides a wireless control knob, including:

[0051] Casing 100;

[0052] The cover 200 is rotatably connected to the housing 100 and moves along the axial direction of the housing 100 when pressed.

[0053] The reset element 300 is disposed on the housing 100 and is used to drive the cover 200 to reset after the cover 200 is released.

[0054] The control module 400 is used to switch and issue corresponding control commands to the vehicle when the cover 200 is rotated and pressed.

[0055] In this application, when the vehicle is in motion and the driver needs to activate a function such as the seat massage function, the driver's eyes do not need to leave the road. In blind operation mode, the driver only needs to rotate and press the cover 200 with one hand. At this time, the control module 400 can confirm and issue a control command to the vehicle. After releasing the hand, the cover 200 can be reset by the reset component 300, reducing the risk of accidental touch and improving driving safety and operating efficiency. Furthermore, by rotating and pressing the entire cover 200, there is no need to operate a button on the cover 200 separately after rotating the cover 200, which improves the convenience of wireless control knob operation.

[0056] Combination Figures 1 to 4 The housing 100 is provided with a plurality of first latches 110 in the circumferential direction. A moving space 111 is formed between the first latches 110 and the bottom wall of the housing 100. The cover 200 is provided with a second latch 210 in the circumferential direction. When the cover 200 is pressed, the second latch 210 disengages from the plurality of first latches 110 and moves within the moving space 111. After the cover 200 is released, the second latch 210 engages with the plurality of first latches 110 through the reset member 300.

[0057] In this application, by employing a first latch 110 and forming a movable space 111 between the first latch 110 and the bottom wall of the housing 100, when the cover 200 rotates the second latch 210, the second latch 210 can rotate within the movable space 111, ensuring that the first latch 110 and the second latch 210 do not affect the rotation of the cover 200. When the cover 200 is pressed, the movable space 111 provides space for the first latch 110 to move along the axial direction of the housing 100, thus not affecting the pressing of the cover 200. When the cover 200 moves away from the housing 100, the first latch 110 can engage with the second latch 210, thereby preventing the cover 200 from detaching from the housing 100.

[0058] In this embodiment, four first buckles 110 are provided, and the four first buckles 110 are evenly distributed along the circumference of the inner bottom wall of the housing 100. Each first buckle 110 includes a first connecting part 112 and a first abutting part 113. The first connecting part 112 is L-shaped and one end of the first connecting part 112 is connected to the inner side wall of the housing 100. The first abutting part 113 is located at the end of the first connecting part 112 away from the inner bottom wall of the housing 100 and extends horizontally toward the axis of the housing 100.

[0059] In this embodiment, the second buckle 210 includes a second connecting portion 211 and a second abutting portion 212. The second connecting portion 211 is coaxially arranged with the cover 200. One end of the second connecting portion 211 is connected to the inner top wall of the cover 200. The second abutting portion 212 is disposed at the end of the second connecting portion 211 away from the cover 200, and the second abutting portion 212 is arranged circumferentially along the second connecting portion 211. The second abutting portion 212 extends horizontally toward the axis of the second connecting portion 211.

[0060] In this embodiment, when the cover 200 is not pressed, the cover 200 drives the first abutting part 113 to abut against the second abutting part 212 through the reset member 300. When the cover 200 rotates, because the first abutting part 113 and the second abutting part 212 abut against each other, and the second abutting part 212 is arranged in a ring, the second abutting part 212 can rotate on multiple first abutting parts 113. When the cover 200 is pressed, the cover 200 drives the first abutting part 113 to disengage from the second abutting part 212, so that the first abutting part 113 moves toward the inner bottom wall of the housing 100. When the cover 200 is released, the cover 200 drives the first abutting part 113 to abut against the second abutting part 212 again through the reset member 300, so as to facilitate the next command.

[0061] In this embodiment, the first abutment 113 on the side away from the inner bottom wall of the housing 100 and the second abutment 212 on the side away from the inner top wall of the cover 200 are both provided with inclined surfaces. When the cover 200 needs to be installed with the housing 100, by moving the cover 200 toward the housing 100, the inclined surface of the second abutment 212 of the cover 200 engages with the inclined surface of the first abutment 113 of the housing 100, thereby pressing the first abutment 113 and the second abutment 212, causing the first abutment 113 to deform toward the inner side wall of the housing 100, and causing the second abutment 212 to deform toward the position where the axis of the cover 200 is located. After the second abutment 212 passes the first abutment 113, the second abutment 212 can move into the moving space 111, realizing the assembly of the cover 200 and the housing 100.

[0062] Combination Figures 1 to 4 The reset member 300 includes a plurality of elastic rods 310 and a plurality of abutment blocks 320. At least one end of the elastic rod 310 is connected to the housing 100. The abutment block 320 is disposed on the corresponding elastic rod 310. The abutment block 320 is used to abut or disengage from the cover 200 when the cover 200 is pressed or released.

[0063] In this application, when the cover 200 is pressed, the cover 200 can abut against the abutment block 320. At this time, the abutment block 320 causes the elastic rod 310 to deform, so that the control module 400 sends a corresponding control command. When the cover 200 is released, the elastic rod 310, due to its elasticity, causes the elastic rod 310 to drive the abutment block 320 to move the cover 200, thereby causing the cover 200 to reset. The use of the elastic rod 310 and the abutment block 320 results in a simple structure and improves the reset efficiency of the cover 200.

[0064] In this embodiment, four sets of elastic rods 310 and abutment blocks 320 are provided. The four abutment blocks 320 are connected to the four elastic rods 310 in a one-to-one correspondence. The four sets of elastic rods 310 and abutment blocks 320 are evenly distributed along the circumference of the housing 100.

[0065] In other embodiments, the number of elastic rods 310 and abutment blocks 320 can be adaptively adjusted as needed, for example, by setting two sets of elastic rods 310 and abutment blocks 320.

[0066] In this embodiment, the elastic rod 310 is arranged along the axis perpendicular to the housing 100. One end of the elastic rod 310 is connected to the housing 100. The abutment block 320 is disposed on the top wall of the elastic rod 310 and is located at the end away from the housing 100, so that when the cover 200 abuts against the abutment block 320, it can better squeeze the abutment block 320 and cause the elastic rod 310 to deform. In other embodiments, both ends of the elastic rod 310 can be connected to the housing 100 and the abutment block 320 can be disposed in the middle of the elastic rod 310, which can also cause the elastic rod 310 to deform.

[0067] In this embodiment, the abutment block 320 is hemispherical. When the cover 200 is pressed, the top of the hemispherical abutment block 320 abuts against the cover 200. In other embodiments, the abutment block 320 may also be cylindrical or other shapes.

[0068] Combination Figures 1 to 4 The edge of the housing 100 is provided with a plurality of grooves 120 along the circumference of the housing 100. One end of the elastic rod 310 is connected to one of the two sides opposite to the groove 120. A deformation space 121 is formed between the elastic rod 310 and the bottom wall of the groove 120. The deformation space 121 is used to allow the elastic rod 310 to move into when the cover 200 is pressed.

[0069] In this application, by using a groove 120 and connecting one end of the elastic rod 310 to the inner wall of the groove 120, the wall thickness of the housing 100 is used to accommodate the elastic rod 310, preventing the elastic rod 310 from occupying part of the space inside the housing 100, thereby indirectly improving the structural compactness of the housing 100 and the elastic rod 310; by using the deformation space 121, space is provided for the deformation of the elastic rod 310 when the cover 200 abuts against the abutment block 320, preventing the elastic rod 310 from failing to deform properly, which would cause the control module 400 to be unable to issue effective control commands.

[0070] In this embodiment, four grooves 120 are provided, and four elastic rods 310 are respectively provided in the four grooves 120. The elastic rods 310 and the housing 100 are integrally provided. The elastic rods 310 are set in an arc shape following the extension direction of the side wall of the housing 100 to prevent the elastic rods 310 from protruding from the grooves 120 and interfering with other components.

[0071] In this embodiment, the groove 120 is U-shaped. In other embodiments, the groove 120 may be semi-circular or other shapes.

[0072] Combination Figures 4 to 8 The wireless control knob also includes a light source 500. The cover 200 includes a rotating part 220 and a light-transmitting part 230. The rotating part 220 is rotatably connected to the housing 100. The top of the rotating part 220 is provided with a mounting port 221. The light-transmitting part 230 is disposed in the mounting port 221. The light source 500 is disposed in the housing 100. The illumination direction of the light source 500 is set towards the light-transmitting part 230. A light-shielding layer 232 is provided on a portion of the outer surface of the light-transmitting part 230.

[0073] In this application, by employing a light source 500, a light-transmitting part 230, and a light-shielding layer 232, the light emitted by the light source 500 can pass through the light-transmitting part 230. The light-shielding layer 232 blocks part of the light, allowing the light-transmitting part 230 to display a specified pattern. This provides the driver with information on the opening and closing of the wireless control knob. For example, a lit light indicates that the wireless control knob is powered and in the open state. It is not necessary to know whether the wireless control knob is powered after operation. Furthermore, by displaying different patterns, the aesthetics of the wireless control knob are indirectly improved.

[0074] In this embodiment, the light source 500 is a surface-mount LED. Surface-mount LEDs are small in size, have low power consumption, and long lifespan, making them suitable for integration into the housing 100 and reducing space occupation.

[0075] In this embodiment, the rotating part 220 is sleeved on the outside of the housing 100. In other embodiments, the rotating part 220 may also be inserted into the inside of the housing 100.

[0076] In this embodiment, the light-transmitting part 230 is tempered glass, and the light-shielding layer 232 is matte black acrylic or polyurethane spray paint with extremely low visible light reflectivity, which can directly absorb light and thus prevent light inside the housing 100 from passing through the light-transmitting part 230.

[0077] In this embodiment, an AF coating is also provided on the light-shielding layer 232. The AF coating is a nanoscale functional film with a thickness of only 10nm-20nm, and its main components are mostly fluoropolymers or fluorosilane compounds. The AF coating makes it difficult for fingerprints, grease and water stains to adhere by significantly reducing the surface energy of the substrate. Even if there are residues, they can be easily wiped away. It also has hydrophobic, oleophobic and self-cleaning effects. The water droplet contact angle is usually large, and the water droplets can quickly roll off and carry away dust. While maintaining the optical transparency and color performance of the light-transmitting part 230, the AF coating can also reduce the surface friction coefficient, improve the smoothness of touch, and enhance the wear resistance and scratch resistance, which indirectly improves the user comfort of the wireless control knob.

[0078] In this embodiment, anti-slip texture 222 is provided on the outer side wall of the rotating part 220. The shape of the anti-slip texture 222 can be adjusted as needed to increase the friction when the driver drives the rotating part 220 to rotate.

[0079] The control module 400 includes a circuit board 410 and an encoder 420. The circuit board 410 is connected to the housing 100, and the encoder 420 is connected to the cover 200. When the cover 200 is rotated and pressed, the encoder 420 rotates and outputs a corresponding electrical pulse signal to the circuit board 410. After receiving the electrical pulse signal, the circuit board 410 switches and sends a corresponding control command to the vehicle.

[0080] In this embodiment, the circuit board 410 is fixedly connected inside the housing 100, and the encoder 420 is fixedly connected inside the cover 200.

[0081] In this embodiment, when four functions (seat massage, seat ventilation, seat heating, and steering wheel heating) need to be activated, the mechanical travel of the cover 200 (360°) is divided into four positions, such as 0°, 90°, 180°, and 270°, which correspond to seat massage, seat ventilation, seat heating, and steering wheel heating, respectively. Rotating the cover 200 causes the encoder 420 to output angle pulses, and the MCU of the circuit board 410 determines the current position of the cover 200 in real time. When the cover 200 is pressed, the circuit board 410 immediately sends the corresponding control command to the vehicle to execute the corresponding control command, thereby activating the corresponding function. After releasing the cover, the cover returns to its original position and waits for the next rotation and pressing.

[0082] In other embodiments, by equally dividing the 360° mechanical travel of the cover 200, the cover 200 can achieve more functions.

[0083] The wireless control knob also includes a wireless module 600 and a power supply unit 700. The wireless module 600 is electrically connected to the control module 400 and is used to wirelessly connect the control module 400 and the vehicle. The power supply unit 700 is disposed inside the housing 100 and is electrically connected to the control module 400. The power supply unit 700 is used to provide power to the control module 400.

[0084] In this application, by adopting the wireless module 600 and the power supply component 700, the entire wireless control knob can be wirelessly connected to the vehicle, eliminating the need for additional wires to electrically connect the wireless control knob and the vehicle. This allows the wireless control knob to be installed in any location within the vehicle, improving the convenience of using the wireless control knob.

[0085] In this embodiment, the wireless module 600 is an antenna, which is mounted on the circuit board 410 and electrically connected to the circuit board 410. The antenna can radiate the encrypted radio frequency signal. On the vehicle side, another antenna is arranged in the roof, dashboard, or BCM to receive the signal. The two antennas establish an air interface link through frequency bands such as 2.4GHz, BLE, or Sub-1GHz. After identity verification is completed, the vehicle sends the control command into the CAN bus to execute the specific function.

[0086] In other embodiments, the antenna mounting position can be adapted as needed, for example, the antenna can be mounted on the inner wall of the housing 100 or the cover 200.

[0087] In this embodiment, the power supply component 700 is a CR3032 button battery. The CR3032 button battery is a non-rechargeable 3V lithium-manganese dioxide button battery with a diameter of 30mm, a thickness of 3.2mm, a nominal capacity of about 500mAh-550mAh, and a weight of about 6.8g. It has the characteristics of low self-discharge, wide operating temperature range from -30℃ to 60℃, and a storage period of 4-10 years.

[0088] In other embodiments, the power supply unit 700 can also be replaced with DL3032, ECR3032 or BR3032. DL3032 and ECR3032 both belong to the lithium-manganese dioxide system, which has low cost and high capacity and is suitable for high current pulses at room temperature; while BR3032 adopts the fluorinated carbon system, which has a flatter voltage curve and more stable low temperature performance, and can still maintain sensitive unlocking in cold environments, with a lifespan of 5 to 7 years.

[0089] In this embodiment, the encoder 420 is provided with a first fixing block 421, and slots 422 are provided on the first fixing block 421 and on both sides of the first fixing block 421. The light-transmitting part 230 is provided with a second fixing block 231 for moving into the slots 422 on both sides. When the rotating part 220 rotates and drives the light-transmitting part 230 to rotate, the light-transmitting part 230 can drive the first fixing block 421 to rotate through the slots 422 and the second fixing block 231, thereby making the first fixing block 421 drive the encoder 420 to rotate, which improves the rotation strength when the light-transmitting part 230 drives the encoder 420 to rotate.

[0090] The housing 100 includes a base 130, a middle frame 140, and a cover plate 150. The middle frame 140 is disposed inside the base 130, and the control module 400 is disposed inside the middle frame 140. The cover 200 is rotatably connected to the middle frame 140. The cover plate 150 is engaged or disengaged from the side of the base 130 away from the cover plate 200. A receiving space 151 for accommodating the power supply component 700 is formed between the control module 400 and the cover plate 150.

[0091] In this application, by engaging or disengaging the cover 200 from the base 130, when the power supply component 700 needs to be replaced, the cover 150 can be separated from the base 130 to facilitate the removal of the power supply component 700 from the receiving space 151, thereby facilitating the replacement of the power supply component 700 and indirectly extending the service life of the wireless control knob.

[0092] In this embodiment, the rotating part 220 of the cover 200 is sleeved and rotatably connected to the outer wall of the middle frame 140, the circuit board 410 of the control module 400 is disposed inside the middle frame 140, and the groove 120 is disposed on the edge of the middle frame 140 away from the cover plate 150.

[0093] In this embodiment, a protrusion 131 is provided on the inner wall of the base 130 along the circumference of the base 130. The annular protrusion 131 is used to limit the power supply component 700, thereby preventing the power supply component 700 from moving within the base 130, and indirectly improving the electrical connection strength between the power supply component 700 and the circuit board 410.

[0094] In this embodiment, a plurality of mounting plates 141 are provided on the inner wall of the middle frame 140 along the circumference of the middle frame 140. The mounting plates 141 and the protrusions 131 are respectively located on both sides of the circuit board 410. The middle frame 140 and the cover plate 150 abut against both sides of the protrusions 131 respectively. Bolts 132 are provided on the protrusions 131. The bolts 132 are used to pass through the circuit board 410 and are used to thread the mounting plates 141, so that the bolts 132 can detachably connect the base 130, the circuit board 410 and the middle frame 140, thereby facilitating the disassembly and assembly of the base 130, the circuit board 410 and the middle frame 140.

[0095] In this embodiment, three snap-fit ​​plates 133 are provided on the protrusion 131 along the circumference of the protrusion 131. When the power supply component 700 moves towards the receiving space 151 along the side of the base 130 away from the cover 200, the power supply component 700 can squeeze the snap-fit ​​plates 133 and cause the snap-fit ​​plates 133 to deform. After the power supply component 700 passes the snap-fit ​​plates 133, the snap-fit ​​plates 133 can abut against the side of the power supply component 700 away from the cover 200, thereby fixing the power supply component 700 in the receiving space 151, preventing the power supply component 700 from moving, and thus improving the fixing strength of the power supply component 700.

[0096] In this embodiment, a snap-fit ​​space is formed between the protrusion 131 and the edge of the base 130 away from the cover 200. The snap-fit ​​space is used to accommodate the cover plate 150. Multiple plates 134 are arranged on the inner wall of the base 130 along the circumference of the base 130. The first plate 134 is located in the snap-fit ​​space. Multiple grooves 152 are arranged on the cover plate 150 along the circumference of the cover plate 150. A rod 153 is arranged on one side of the opposite sides of the groove 152. The plate 134 is arranged in an "L" shape. An inlet 157 is formed between the rod 153 and the inner wall of the groove 152 for the plate 134 to be moved in.

[0097] In this embodiment, a first protrusion 135 is provided on the surface of the plate 134 facing the protrusion 131, and a second protrusion 154 is provided on the surface of the rod 153 facing the bottom wall of the groove 152. The first protrusion 135 is used to abut against the second protrusion 154.

[0098] When the cover plate 150 needs to be installed, by moving the cover plate 150 toward the snap-fit ​​space, the cover plate 150 can move the groove 152 toward the plate 134. The plate 134 can be moved into the groove 152 through the inlet 157. By rotating the cover plate 150, the cover plate 150 can drive the second protrusion 154 to press against the first protrusion 135 and pass over the first protrusion 135, so that the cover plate 150 drives the rod 153 to move into the "L"-shaped plate 134 and the protrusion 131. At this time, the first protrusion 135 and the second protrusion 154 abut against each other, so that the cover plate 150 and the base 130 are snapped together by the rod 153 and the plate 134. When the cover plate 150 needs to be removed, by rotating the cover plate 150 in the opposite direction and moving the cover plate 150 away from the protrusion 131, the rod 153 and the plate 134 are disengaged, so that the cover plate 150 can be removed.

[0099] In this embodiment, a rotating groove 155 is provided on the surface of the cover plate 150 away from the cover body 200 and in the middle of the cover plate 150. The rotating groove 155 is arc-shaped, and the rotating groove 155 makes it convenient for the user to rotate the cover plate 150.

[0100] In this embodiment, an adhesive layer 156 is provided on the surface of the cover plate 150 opposite to the cover body 200, which facilitates attaching the entire wireless control knob to any position inside the vehicle. In other embodiments, a magnet can also be provided on the surface of the cover plate 150 opposite to the cover body 200, which can be used to attract the entire wireless control knob to the inside of the vehicle.

[0101] A plurality of toggle beads 160 are elastically connected to one of the outer side wall of the housing 100 and the inner side wall of the cover 200, and a plurality of stop grooves 240 are provided on the other side of the outer side wall of the housing 100 and the inner side wall of the cover 200. The stop grooves 240 are used to allow the toggle beads 160 to move in or out when the cover 200 rotates.

[0102] In this application, by adopting the configuration of the dial ball 160 and the gear slot 240, when the cover 200 rotates, the cover 200 can drive the dial ball 160 to move circumferentially. When the dial ball 160 moves to the position of the gear slot 240, the dial ball 160 can be elastically abutted in the gear slot 240, at which time an audible prompt can be made to the user, so that the user can have a clear feel when rotating the dial ball 160.

[0103] In this embodiment, the dial ball 160 is disposed on the outer wall of the middle frame 140 of the housing 100, and the gear slot 240 is disposed on the inner side wall of the rotating part 220 of the cover 200. The number of dial balls 160 can be less than the number of gear slots 240. The number of gear slots 240 is the same as the number of gears of the encoder 420. For example, when four functions (seat massage, seat ventilation, seat heating and steering wheel heating) need to be activated, four gear slots 240 are provided and evenly distributed along the circumference of the cover 200. When the cover 200 moves the dial ball 160 into the four gear slots 240 respectively, it means that the encoder 420 has rotated to the corresponding position. At this time, pressing the button will send the corresponding control command through the circuit board 410.

[0104] In other embodiments, the encoder 420 may have 30 gear positions and 30 gear position slots 240, so that the encoder 420 and the circuit board 410 can enable 30 different functions.

[0105] In this embodiment, a plurality of receiving grooves 142 are provided on the outer side wall of the middle frame 140 of the housing 100. Each receiving groove 142 is provided with a spring 143. One end of the spring 143 is connected to the bottom wall of the receiving groove 142. A plurality of toggle beads 160 are connected to the other end of the plurality of springs 143 respectively. The toggle beads 160 are elastically connected to the outer wall of the middle frame 140 of the housing 100 through the springs 143.

[0106] In this embodiment, the bead 160 is spherical; in other embodiments, the shape of the bead 160 can be adapted as needed, for example, the bead 160 can be set as a cylinder or a hemisphere.

[0107] This application also provides a vehicle, including a vehicle body and a wireless control knob of any of the above embodiments disposed on the vehicle body.

[0108] The specific structure of the wireless control knob has been described in detail in the above embodiments, and will not be repeated here.

[0109] In this embodiment, the vehicle may be a sedan, truck, car, or tram, etc.

[0110] The vehicle provided in this application, through the installation of a wireless control knob, activates a function such as the seat massage function. This is achieved by rotating the rotating part 220, which in turn rotates the encoder 420. When the dial 160 moves to the corresponding position in the gear slot 240, the dial 160 abuts against the bottom wall of the gear slot 240 due to the elasticity of the spring 143, emitting an audible signal to the driver that the rotating part 220 has reached its position. This causes the encoder 420 to output an angle pulse. The MCU of the circuit board 410 determines the current position of the rotating part 220 in real time. By pressing the rotating part 220 or the light-transmitting part 230, when the cover 200 is pressed, the circuit board 410 immediately sends the corresponding control command to the vehicle, executing the control command corresponding to the seat massage function. This activates the seat massage function. When the cover 200 is pressed, the inner wall of the rotating part 220 abuts against the abutment block 320. At this time, the abutment block 320 causes the elastic rod 310 to deform, and the elastic rod 310 can move towards the deformation space 121. When the user releases the cover 200, the elastic rod 310, due to its elasticity, causes the elastic rod 310 to drive the abutment block 320 to drive the rotating part 220 to move, thereby causing the rotating part 220 to reset the cover 200, waiting for the next round of rotation and pressing. When the vehicle is in motion, if the driver needs to activate a function of the vehicle, such as the seat massage function, the driver's eyes do not need to leave the road. In blind operation mode, the driver only needs to twist and press the cover 200 with one hand, reducing the risk of accidental touch and improving driving safety and operating efficiency.
