Description

Technical Field

[0001] The invention relates to the field of vehicle-mounted switches, and in particular to a multifunctional screen-mounted knob. Background Art

[0002] The entertainment system in the vehicle control system often uses a multi-function knob for selection and control. The knob usually needs to complete multiple motion modes to complete the control of the entertainment system. It has high reliability requirements, and harsh durability conditions and high and low temperature conditions. This makes it difficult for various control modes to complete the sensing control work in a single sensing chip of a control component in the vehicle control system. How to sense and identify multiple control functions through one chip has become a technical difficulty. On the other hand, most of the knobs currently installed above the vehicle touch screen only have pressing or rotating functions, and there is no knob structure that can achieve independent swing control, making it difficult to achieve separate and accurate control of more and more functions in the vehicle control system on a diversified basis. The above shortcomings of the lack of independently working swing components based on only pressing and rotating functions and the shortcomings of the pressing, rotating and swinging structures that are difficult to achieve sensing control work through a sensing chip have brought certain troubles to people. Summary of the invention

[0003] In view of the deficiencies in the prior art, the present invention provides a multifunctional screen-mounted knob which has a separate swing control function on the basis of pressing and rotating functions and can perform sensing work through a single sensing chip.

[0004] In order to solve the above technical problems, the present invention is solved by the following technical solutions:

[0005] A multifunctional screen-mounted knob includes a knob body attached to the upper surface of a carrier and inductively connected to a sensing component, wherein the knob body includes a rotating component, a pressing component, and a swinging component which are arranged in a knob housing and can work independently. This arrangement allows users to realize more functional controls in the vehicle control system, and the manual control of each function does not affect the selection of other control functions, which not only increases the diversity of control forms but also makes the control more precise. In terms of appearance function control, the physical movements of swinging, pressing, and rotating are relatively independent, but all the moving pairs are finally integrated into a single magnetic part, breaking the opposition and unity of the traditional structure and confirming the breakthrough of the contradiction in structural technology. The magnetic part then performs the sensing work through the sensing chip of a single sensing component. Compared with the traditional structure in which a single sensing chip can only realize two functional controls, it reduces the cost of the vehicle control system and provides convenience for people.

[0011] Preferably, the sensing component includes a Hall chip capable of sensing changes in a magnetic field and a circuit board electrically connected to the Hall chip.

[0012] Preferably, the knob body is connected to the carrier by pasting, which can avoid physical damage to the carrier caused by other destructive connection methods, such as rotating holes and installing brackets to fix the connection, and pasting connection can also improve utilization and perform multiple installation connections.

[0013] Preferably, the carrier includes glass, plastic and any non-magnetic metal material.

[0020] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0021] See Figures 1 to 3 A multifunctional screen-mounted knob includes a knob body 5 attached to the upper surface of a carrier 2 and inductively connected to a sensing component 3. The carrier 2 is a panel provided for sensing between the knob body 5 and the sensing component 3. The carrier 2 includes glass, plastic, and any non-magnetic metal material. The sensing component 3 generates a corresponding electrical signal by sensing the change of the magnetic field in the knob body 5. The knob body 5 includes a rotating component 42, a pressing component 41, and a swinging component 43, which are provided in a knob housing 51 and can work independently. The rotating component 42, the pressing component 41, and the swinging component 43 can all drive the magnetic part 16 to move. The pressing component 41 is a component that can output a confirmation or cancellation instruction after the user presses it. The rotating component 42 is a component that the user can adjust the amplitude range of the corresponding function. The knob body 5 can perform corresponding operations to allow the user to adjust to the desired function. The swinging component 43 is a component that can swing in multiple directions and can realize the corresponding function after swinging in the corresponding direction.

[0022] The swing assembly 43 includes a swing cover 11, a plurality of support rods arranged below the swing cover 11, a support rod elastic base 13 arranged at the lower end of the support rod, a second swing member 14 that can swing after being subjected to an external force, a central column 15 horizontally limitedly connected to the second swing member 14, and a magnetic member 16 located below the central column 15. The swing convex ring 141 on the second swing member 14 is arranged opposite to the support rod protrusion on the support rod up and down. The support rod is used as a fulcrum for the swing assembly 43 to realize the swing function. The magnetic member 16 is arranged opposite to the induction assembly 3. The support rod includes a first support rod 12, a second support rod 17 and a third support rod group perpendicular to the connection line direction of the first support rod 12 and the second support rod 17. The third support rod group is also composed of two opposite support rods, which are evenly distributed in the space directly below the swing cover 11 with the first support rod 12 and the second support rod 17. The support rod protrusion includes a first support rod protrusion 121 on the first support rod 12 and a second support rod protrusion 122 on the second support rod 17.

[0023] The swing assembly 43 also includes a spring 142, a sleeve 143, a second rotating frame 423, and a swing frame 425. The sleeve 143 is fixedly connected to the center column 15. The second rotating frame 423 rotates simultaneously when the knob body 5 rotates, and the second rotating frame 423 does not change in the vertical and horizontal directions. The swing frame 425 is connected to the second swing member 14 and the second rotating frame 423 by means of shaft hole matching and vertically movable connection. This connection method allows the second swing member 14 to achieve a swinging motion after being subjected to force.

[0024] The swing cover 11 is a ring-shaped structure. The user can press one end of the swing cover 11 to swing and realize the corresponding function. The support rod elastic base 13 is used to support the support rod including the first support rod 12 and the second support rod 17. The support rod elastic base 13 has a certain elasticity. The support rod elastic base 13 includes a rubber seat with elasticity and a plastic. The swing convex ring 141 on the second swing member 14 and the first support rod convex block 121 on the first support rod 12 and the second support rod convex block 122 on the second support rod 17 The upper and lower parts are arranged relatively to each other, and the magnetic part 16 is arranged relatively to the induction component 3. The second swinging part 14 is a part that is connected to the center column 15 through the limiting groove and the limiting rib and can realize swinging. The limiting groove and the limiting rib are arranged in the vertical direction. The second swinging part 14 and the center column 15 can slide against each other in the vertical direction and be clamped and limited in the horizontal direction. That is, the center column 15 and the second swinging part 14 can perform synchronous actions when subjected to force in the horizontal direction, and slide against each other when subjected to force in the vertical direction. The swinging convex ring 141 is integrally connected with the second swinging part 14.

[0025] In addition to the swinging operation in two directions with the first support rod 12 and the second support rod 17 as the fulcrum, the swing assembly 43 can also be provided with a pair or more of support rods as the fulcrum of the swing assembly component, so that the swing assembly 43 has more functions.

[0026] When the user operates the swing assembly 43, the user presses the swing cover 11 above the first support rod 12 with his hand, and the blind hole at the lower end of the swing cover 11 that matches the first support rod 12 moves downward through the first support rod 12 in the form of an axial hole. The first support rod 12 is cylindrical in shape, and the first support rod 12 and the fixing member 421 also move in the form of an axial hole. The fixing member 421 is a support shell in the knob body 5 that is attached to the carrier 2. At this time, the swing cover 11 only swings relative to the fixing member 421, and the first support rod 12 moves downward. The elastic base 13 of the support rod is deformed downward after being compressed, and the first support rod protrusion 121 on the first support rod 12 moves downward at the same time and squeezes the position of the swing convex ring 141 below it to move downward. As mentioned above, at this time, the swing convex ring 141 swings, and the center column 15 connected to its horizontal limit and the magnetic member 16 fixedly connected to the center column 15 swing at the same time. The induction component 3 arranged opposite to the magnetic member 16 senses the change in the magnetic field generated by the magnetic member 16 and generates a corresponding electrical signal to assist in detecting the swinging action of the swinging component 43.

[0027] The pressing component 41 includes a pressing cover 19, an elastic block 20, a central column 15, an upper central column 18 above the central column 15, a second swinging member 14 connected to the central column 15, a magnetic member 16 fixedly connected to the central column 15, a spring 142 inside the second swinging member 14, and a sleeve 143 located above the spring 142. The elastic block 20 is a block-shaped body with a certain elasticity. When the user operates the pressing component 41, the pressing cover 19 is pressed downward by hand, and the elastic block 20 below the pressing cover 19, the upper central column 18, the central column 15 that can slide relative to the second swinging member 14 in the vertical direction, the sleeve 143 fixedly connected to the central column 15, and the magnetic member 16 fixedly connected to the central column 15 move downward at the same time, wherein the central column 15 and the second swinging member 14 are movably connected in the up and down directions, and the sensing component 3 generates a corresponding electrical signal after sensing the magnetic field change of the magnetic member 16. During this process, the swing frame 425 is connected to the second swing member 14 and the second rotating frame 423 by means of shaft hole cooperation. The second swing member 14 does not move with the up and down movement of the center column 15. At the same time, the socket 143 connected to the center column 15 compresses the spring 142 downward. When the external force disappears, the spring 142 and the elastic block 20 begin to rebound and make an upward rebound movement.

[0028] The rotating assembly 42 includes a knob housing 51, a first rotating frame 422 fixedly connected to the knob housing 51, a second rotating frame 423 arranged on the fixing member 421 of the knob body 5, a magnet group 424 arranged on the first rotating frame 422 and the second rotating frame 423, a swing frame 425, a spring 142, a bearing 426, a sleeve 143, a center column 15, a second swinging member 14 horizontally limitedly connected to the center column 15, and a magnetic member 16 fixedly connected to the center column 15. The knob housing 51 is used for rotation by the user, the fixing member 421 is a supporting shell in the knob body 5 that is attached to the carrier 2, the second rotating frame 423 and the fixing member 421 can be supported and fixed in the vertical direction and rotated and slidable in the horizontal direction, the magnet groups 424 on the first rotating frame 422 and the second rotating frame 423 are respectively fixedly connected to the first rotating frame 422 and the second rotating frame 423, and the second rotating frame 423 and the second swinging member 14 and the second rotating frame 423 are connected through the shaft The second swing member 14 is connected by a hole-matching connection method. This connection method not only allows the second swing member 14 to realize a swinging action after being subjected to force, but also allows the second swing member 14 to rotate with the rotation of the second rotating frame 423. The magnet groups 424 located on the first rotating frame 422 and the second rotating frame 423 are arranged in a manner of opposite poles attracting each other, so that when the first rotating frame 422 rotates, the second rotating frame 423 is driven to rotate due to the suction force of the magnet group 424. When the user operates the rotating component 42, the knob housing 51 is turned by hand, and the knob housing 51 and the fixing member 421 are matched with each other through the bearing 426 therebetween to rotate with each other. The first rotating frame 422 rotates at the same time, and the second rotating frame 423 also rotates at the same time through the action of the magnet group 424. After the second rotating frame 423 rotates, it drives the second swing member 14 to rotate, and the second swing member 14 then drives the center column 15 and the magnetic member 16 to rotate. The induction component 3 generates a corresponding electrical signal after sensing the magnetic field change of the magnetic member 16.

[0029] The sensing component 3 includes a Hall chip 31 that can sense changes in a magnetic field and a circuit board 32 that is electrically connected to the Hall chip 31 . The Hall chip 31 is a component in the sensing component 3 that senses changes in a magnetic field and cooperates with the circuit board 32 to generate an electrical signal.

[0030] The knob body 5 is connected to the carrier 2 by pasting, and is connected to the carrier 2 by a stable adhesive medium, such as glue, tape, etc., which can avoid physical damage to the carrier 2 caused by other destructive connection methods, such as turning holes and installing brackets to fix the connection. In addition, the pasting connection can also improve utilization and perform multiple installation connections.

[0031] The carrier 2 is made of a light-transmitting material. The circuit board 32 on the sensing component 3 can emit light with an indicating function. When the carrier 2 is made of a light-transmitting material, the light can be transmitted to the knob body 5 through the carrier 2. The user can know the state of the knob body 5 by observing the indicating light on the knob body 5, which not only increases the aesthetic effect but also facilitates people's operation.

[0032] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of ordinary technicians in this field without departing from the purpose of the present invention.
