Description

Technical Field

[0001] This utility model relates to the field of knob technology, and in particular to a capacitive knob with a pressing function. Background Technology

[0002] In pursuit of simplicity, technological sophistication, and aesthetics in automotive interiors, the current automotive industry widely adopts large touchscreens to integrate and control various vehicle functions, significantly reducing the use of traditional knobs and buttons. However, this all-touchscreen design requires drivers to focus their gaze on the screen for precise clicks when operating virtual controls, making blind operation impossible. This visual distraction greatly increases safety risks during driving.

[0003] To alleviate the aforementioned problems, existing technologies use capacitive knobs, which to some extent provide tactile feedback and operational intuition similar to physical knobs. However, most existing capacitive knobs typically lack axial on / off pressing functionality. In many operational logics, after knob adjustment, a "confirmation" or "on / off" action is required to ultimately execute the command. The driver still needs to tap the corresponding virtual confirmation button on the touchscreen to complete the entire operation. This not only fails to completely achieve blind operation but also makes the interaction more cumbersome and distracts the driver's attention by requiring back-and-forth movement between the knob and the screen.

[0004] Therefore, there is an urgent need for a capacitive knob with a pressing function to solve the above-mentioned technical problems. Utility Model Content

[0005] The purpose of this utility model is to provide a capacitive knob with a pressing function. The capacitive knob with the pressing function can realize the pressing operation at any position, and has a simple structure, stable reliability and long service life.

[0040] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0041] like Figures 1 to 6As shown, this embodiment provides a capacitive knob with a pressing function. The capacitive knob with a pressing function includes a base 1, a knob body 2, an outer knob assembly 3, and a reset assembly 4. The knob body 2 is fitted onto the base 1 and can rotate around the axis of the base 1. A rotation sensor 21 and a pressing sensor 22 are provided on the knob body 2. The outer knob assembly 3 is disposed on the knob body 2 and movably engages with it. Pressing the outer knob assembly 3 electrically connects it to both the rotation sensor 21 and the pressing sensor 22. The reset assembly 4 is disposed between the knob body 2 and the outer knob assembly 3. Releasing the pressure on the outer knob assembly 3 causes it to reset, separating it from the rotation sensor 21 and the pressing sensor 22. This capacitive knob with a pressing function has both rotation and pressing functions. The driver can complete the entire operation process simply by operating the capacitive knob with the pressing function, without needing to click on a touchscreen, thus achieving blind operation and avoiding distraction of the driver's attention. Meanwhile, the outer button assembly 3 and the reset assembly 4 together form a ring-push-press structure. Pressing any position of the outer button assembly 3 will electrically connect the outer button assembly 3 with the rotation sensor 21 and the press sensor 22, making operation convenient. Moreover, the capacitive knob with the pressing function has a simple structure, stable reliability, and long service life.

[0042] Specifically, both the base 1 and the knob body 2 are annular structures. The base 1 includes a connecting part 12 and a positioning part 13. The outer diameter of the connecting part 12 is smaller than the outer diameter of the positioning part 13. The knob body 2 is fitted onto the connecting part 12 with a clearance fit. The positioning part 13 abuts against the side of the knob body 2 facing away from the outer button assembly 3. A rotation sensor 21 and a press sensor 22 are respectively disposed on opposite sides of the knob body 2 about the central axis.

[0043] Optionally, the outer button assembly 3 includes a touch ring 31 and two conductive elements 32. The touch ring 31 is movably engaged with the knob body 2, and both conductive elements 32 are electrically connected to the touch ring 31. A rotation sensor 21 and a press sensor 22 each correspond to one conductive element 32. When the touch ring 31 is pressed, the rotation sensor 21 and the press sensor 22 become electrically connected to their respective conductive elements 32. When the pressure on the touch ring 31 is released, the touch ring 31 resets, thereby moving the two conductive elements 32 and separating them from the rotation sensor 21 and the press sensor 22, thus disconnecting the connection. Specifically, the conductive elements 32 are metal springs. The two conductive elements 32 extend along the axial direction of the touch ring 31.

[0044] Optionally, the outer button assembly 3 also includes an outer button ring 33, which is movably connected to the knob body 2 along the axial direction of the knob body 2. The touch ring 31 is fixedly connected to the outer button ring 33 on the side facing away from the knob body 2. By providing the outer button ring 33, it is convenient to connect the touch ring 31 to the knob body 2, providing stability when pressing the touch ring 31. At the same time, rotating the outer button ring 33 drives the knob body 2 to rotate, which is convenient for the driver to operate.

[0045] Specifically, such as Figure 1 as well as Figures 6 to 8 As shown, the inner wall of the outer button ring 33 is provided with a snap-fit ​​protrusion 332, and the knob body 2 is provided with a slot corresponding to the snap-fit ​​protrusion 332. A hook 23 is provided in the slot. The snap-fit ​​protrusion 332 snaps into the hook 23 and the snap-fit ​​protrusion 332 can move along the axial direction of the knob body 2 in the slot so that the outer button assembly 3 can be pressed.

[0046] Optionally, the reset assembly 4 includes a reset block 41 and a reset spring 42. The reset block 41 is connected to the knob body 2, and the reset spring 42 is disposed on the reset block 41. When the touch ring 31 is pressed, the outer button ring 33 abuts against the reset spring 42, the reset spring 42 is compressed, the pressure on the touch ring 31 is released, the reset spring 42 restores its deformation, thereby pushing the outer button assembly 3 to reset.

[0047] Optionally, the outer button ring 33 has a boss 331 on the side facing the reset block 41, and the reset block 41 has a groove 411 corresponding to the boss 331. The sidewall of the groove 411 is inclined relative to the axial direction of the outer button ring 33. The reset spring 42 is disposed in the groove 411 and extends radially along the outer button ring 33. When the touch ring 31 is pressed, the boss 331 moves into the groove 411, and the boss 331 abuts against the inclined sidewall of the groove 411. The reset spring 42 is compressed, releasing the pressure on the touch ring 31. The reset spring 42 returns to its original deformation, pushing the boss 331 back to its original position. By extending the reset spring 42 radially along the outer button ring 33, installation space can be saved.

[0048] Specifically, the reset block 41 has a ring-shaped structure, and an annular placement groove is provided on the side of the knob body 2 facing the reset block 41, in which the reset block 41 is placed. A protrusion 24 is provided on the inner wall of the placement groove, and a positioning groove 412 corresponding to the protrusion 24 is provided on the inner wall of the reset block 41, in which the reset block 41 is engaged. In other embodiments, the reset spring 42 can extend axially along the knob body 2, with one end abutting against the reset block 41 and the other end abutting against the outer knob ring 33.

[0049] Optionally, a protective layer is provided on the outer wall of the outer button ring 33 to enhance the overall aesthetics and durability of the capacitive knob with a pressing function. Specifically, a piano lacquer coating is first applied to the outer wall of the outer button ring 33 using a spraying process, and then a layer of transparent high-gloss UV protective varnish is applied to the outer wall of the outer button ring 33.

[0050] Optionally, such as Figure 1 and Figure 5 As shown, the capacitive knob with a pressing function also includes a switch assembly 5. The switch assembly 5 is disposed on the knob body 2 and corresponds to the pressing sensor 22. When the touch ring 31 is pressed, the conductor 32 triggers the switch assembly 5, so that the touch ring 31 and the pressing sensor 22 are electrically connected. Specifically, the switch assembly 5 includes a circuit board and a tactile switch. The circuit board is fixedly connected to the knob body 2 and corresponds to the pressing sensor 22. The tactile switch is soldered onto the circuit board, and one of the conductors 32 corresponds to the tactile switch.

[0051] Optionally, such as Figure 1 and Figure 2 As shown, the capacitive knob with a pressing function also includes a positioning spring 6 and a positioning element 7. The positioning spring 6 is connected to the knob body 2, and the positioning element 7 is connected to the positioning spring 6. A positioning protrusion 11 is provided on the side wall of the base 1. When the knob body 2 is rotated, the positioning protrusion 11 corresponds to the positioning element 7, and the positioning protrusion 11 can abut against the positioning element 7, compressing the positioning spring 6. When the positioning protrusion 11 moves away from the positioning element 7, the positioning spring 6 restores its deformation, pushing the positioning element 7 to move. By setting the positioning spring 6 and the positioning element 7, a positioning feel can be generated between the outer knob assembly 3 and the base 1 when the outer knob assembly 3 is rotated, improving the driver's experience. Specifically, the positioning element 7 is a steel ball. The positioning spring 6 and the positioning element 7 are installed in a placement groove. A through hole is provided on the side wall of the placement groove. The diameter of the through hole is smaller than the diameter of the steel ball, and the steel ball can partially protrude from the through hole to abut against the positioning protrusion 11.

[0052] Optionally, the capacitive knob with a pressing function also includes an inner shell 8, which is detachably connected to the base 1. By providing the inner shell 8, the overall structural strength and aesthetics of the capacitive knob with a pressing function can be improved. Specifically, the inner shell 8 is ring-shaped and located inside the outer knob ring 33. The inner shell 8 is snapped and fixed to the connecting part 12. A protective layer is provided on the outer wall of the inner shell 8, which can improve the overall aesthetics and durability of the capacitive knob with a pressing function. First, a piano lacquer coating is sprayed onto the outer wall of the inner shell 8 using a spraying process, and then a layer of transparent high-gloss UV protective paint is applied to the outer wall of the inner shell 8.

[0053] Optionally, a double-sided adhesive sticker 9 is provided on the side of the base 1 facing away from the knob body 2, which facilitates the attachment of the knob body 2 to the mounting surface of the vehicle. Specifically, the double-sided adhesive sticker 9 is 3M double-sided adhesive, which has strong adhesion and water resistance.

[0054] The capacitive knob with pressing function in this embodiment has a compact, flat overall structure that is easy to install, effectively improving the stability of the capacitive knob with pressing function.

[0055] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here.
