[0038] In order to make the technical problem solved by the present invention, the technical solution adopted and the technical effect achieved more clearly, the technical solution of the present invention is further explained below with reference to the accompanying drawings and through specific implementation methods.

[0039] In the description of the present invention, unless otherwise clearly specified and limited, the terms "connected", "connected", and "fixed" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0040] In the present invention, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may include that the first and second features are in direct contact, or may include that the first and second features are not in direct contact but are in contact through another feature between them.

A first feature being "below", "below" and "below" a second feature includes that the first feature is directly below and obliquely below the second feature, or simply indicates that the first feature is lower in level than the second feature.

[0041] In the description of this embodiment, the terms "upper", "lower", "left", "right" and other directions or positional relationships are based on the directions or positional relationships shown in the drawings, and are only for the convenience of description and simplification of operation, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operate in a specific direction, and therefore cannot be understood as limiting the present invention. In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0042] like Figure 1 and Figure 2 As shown, this embodiment provides a switch knob, which includes a fixed component 1, a rotating component 4, a switch component 2 and a shift component 3. The fixed component 1 is detachably connected to the touch screen, and the rotating component 4 is rotatably sleeved outside the fixed component 1. The switch component 2 and the shift component 3 are arranged on the rotating component 4 and are located between the fixed component 1 and the rotating component 4. The shift component 3 is connected to the touch screen to form a coupling capacitor. The shift component 3 is configured to rotate to select any functional module on the touch screen, and the switch component 2 can be connected to the touch screen corresponding to the selected functional module to form a coupling capacitor. The switch component 2 and the shift component 3 are both made of conductive materials, and the fixed component 1 is made of insulating material.

[0043] In the prior art, the working principle of the capacitive touch screen is that when a finger touches the touch screen, a coupling capacitor is formed between the user and the surface of the touch screen, and the position of the touch point is obtained by calculation and processing by the controller. The principle of the switch knob in the present invention is that the user's finger connects the human body electric field with the surface of the touch screen through the gear component 3 and the switch component 2 in the switch knob to form a coupling capacitor, wherein the gear component 3 is always connected to the user's finger, that is, the gear component 3 is always in an electrically conductive state with the touch screen. Specifically, the user's finger operates the switch knob, and the switch component 2 and the gear component 3 are driven to rotate by rotating the rotating component 4, so that the gear component 3 and the surface of the touch screen form a coupling capacitor, realizing the function of being able to select the function modules at different positions of the touch screen, wherein for most touch screens, when a certain function module is selected, the corresponding function module will be highlighted to remind the user; in the process of rotating the switch knob, the switch component 2 does not form a coupling capacitor with the touch screen, and after a certain function module is selected, the user presses the switch component 2 to connect the finger with the touch screen to generate a coupling capacitor, and finally realizes the confirmation of the selected function module.

[0044] When using the switch knob, the user only needs to operate the switch knob without observing, clicking, and confirming the entire touch screen. The switch knob pasted on the touch screen can be directly installed on the touch screen for use without destroying the integrity of the touch screen, ultimately achieving partial blind operation and improving driving safety.

[0045] Specifically, Figure 3 As shown, the shift assembly 3 includes a first spring 31 and a first conductive sheet 32 ​​abutting against the bottom of the first spring 31. The first spring 31 is configured to conduct a human finger and the first conductive sheet 32. The first conductive sheet 32 ​​is arranged at the bottom of the rotating assembly 4 and abuts against the surface of the touch screen to form a coupling capacitor. Through the first spring 31 and the first conductive sheet 32 ​​made of metal, the finger and the touch screen are always in conduction, so as to realize the function of selecting different functional modules on the touch screen.

[0046] like Figure 4 As shown, the switch assembly 2 includes a second spring 21, a first pot piece 22, and a second conductive sheet 24 arranged from top to bottom. The first pot piece 22 is configured to be electrically connected to the second conductive sheet 24. The second conductive sheet 24 is arranged at the bottom of the rotating assembly 4 and abuts against the surface of the touch screen to form a coupling capacitor. The second spring 21 is configured to be able to conduct a human finger and the first pot piece 22. The finger is electrically connected to the first pot piece 22 through the second spring 21, and the second conductive sheet 24 is electrically connected to the touch screen. Whether the first pot piece 22 and the second conductive sheet 24 are electrically connected determines whether the finger is electrically connected to the touch screen. If the first pot piece 22 and the second conductive sheet 24 are electrically connected, the confirmation function of the selected functional module can be realized. As shown Figure 4 As shown, the switch assembly 2 further includes a contact piece 23. The contact piece 23 serves to support and electrically connect the second spring 21 and the first pot piece 22.

[0047] Specifically, the contact sheet 23 includes a first support portion 231 and a second support portion 232 that are electrically connected to each other, and the second conductive sheet 24 includes a first conductive portion 241 and a second conductive portion 242 that are electrically connected to each other, wherein the first conductive portion 241 is in a state of being electrically connected to the surface of the touch screen. The contact sheet 23 plays the role of electrically connecting the second spring 21 and the first pot piece 22. Specifically, the first support portion 231 supports and is connected to the first pot piece 22, and the second support portion 232 supports and is connected to the second spring 21, thereby achieving electrical connection between the second spring 21 and the first pot piece 22. The first support portion 231 is a semi-annular structure, and the second conductive portion 242 is located in the semi-annular structure. The first pot piece 22 can be pressed downward to be electrically connected to the second conductive portion 242 and then to the first conductive portion 241, and finally achieve electrical connection between the finger and the touch screen.

[0048] like Figure 2 and Figure 5As shown, the rotating assembly 4 includes a support 411 and a rotating part 412 arranged from bottom to top, the rotating part 412 is sleeved outside the support 411 and can drive the support 411 to rotate, the switch assembly 2 and the gear assembly 3 are arranged on the support 411, and the rotating part 412 is configured to press the first pot piece 22 in the vertical direction. The rotating part 412 drives the support 411, the switch assembly 2 and the gear assembly 3 to rotate to select a functional module. After determining a certain functional module, the rotating part 412 is pressed in the vertical direction to press the first pot piece 22, and the first pot piece 22 is electrically connected to the touch screen, thereby realizing electrical conduction between the finger and the touch screen, and realizing confirmation of the corresponding functional module. Among them, the support 411 and the rotating part 412 are both made of insulating materials.

[0049] Furthermore, the rotating component 4 also includes a touch ring 42, which is clamped on the upper part of the rotating part 412, and the touch ring 42 can rotate with the rotating part 412. Among them, the touch ring 42 is a conductive material, and in the present embodiment, it is preferably a plastic material electroplated with a chromium layer. The first spring 31 and the second spring 21 are both in contact with the touch ring 42, and the finger presses the touch ring 42 in the vertical direction, and the touch ring 42 presses the rotating part 412 downward, and the rotating part 412 moves downward to press the first pot piece 22. Among them, the first spring 31 and the second spring 21 play a role of rebounding and resetting the touch ring 42, that is, after the finger stops pressing, the touch ring 42 will return to its original state.

[0050] like Figure 6 The following is a partial structural diagram of the switch knob. Figure 6 The support 411, the first pot piece 22, the first conductive sheet 32 ​​and the second conductive sheet 24 are not shown. A pressing portion 4121 is convexly provided at the bottom of the rotating portion 412. The pressing portion 4121 is arranged just above the first pot piece 22. The pressing portion 4121 can press the first pot piece 22 in the vertical direction. The pressing portion 4121 is a convex column structure convexly provided on the bottom surface of the rotating portion 412. The convex column structure is directly opposite to the center position of the first pot piece 22. When the rotating portion 412 moves in the vertical direction, the convex column structure abuts against and presses the first pot piece 22, so that the pressed position of the first pot piece 22 is in contact with the second conductive portion 242 for electrical conduction.

[0051] Preferably, in order to enhance the hand feeling when the rotating part 412 is pressed downward, two or more convex column structures identical to the pressing part 4121 are provided in the circumferential direction of the bottom of the rotating part 412, and pot pieces are provided correspondingly below the convex column structures. When the rotating part 412 is pressed, the hand feeling of the user can be enhanced, and the user experience can be improved.

[0052] like Figure 7As shown, the fixing assembly 1 includes a base 11 and a fixing base 12. The support 411 is rotatably sleeved on the base 11, the support 411 and the rotating part 412 are both hollow structures, the fixing base 12 passes through the rotating part 412 and the support 411 and is clamped on the base 11, and the upper surface of the touch ring 42 is not lower than the upper surface of the fixing base 12. The base 11 can be adhered to the surface of the touch screen with glue, double-sided tape or other sticky materials, and the switch knob can be used directly on the touch screen without destroying the integrity of the touch screen surface.

[0053] Preferably, a wave portion 111 is provided on the circumferential surface of the base 11, and an elastic positioning component 5 used in conjunction with the wave portion 111 is provided on the support 411. One end of the elastic positioning component 5 abuts against the wave portion 111, and the other end is fixed to the support 411. The elastic positioning component 5 can rotate along the circumferential direction with the support 411 to abut against different troughs of the wave portion 111. When the switch knob is turned, the rotating portion 412 drives the support 411 to rotate, and the elastic positioning component 5 will continuously expand and contract to abut against different troughs of the wave portion 111 to form a sense of frustration, enhance the user's hand feel when rotating, and improve the user's experience.

[0054] Furthermore, if Figure 5 and Figure 8 As shown, a positioning hole 4111 is formed on the side wall of the support 411. The elastic positioning assembly 5 includes a cylindrical positioning sleeve 51, a positioning spring 52 and a positioning baffle 53. Among them, one end of the positioning sleeve 51 is closed and abuts on the wave portion 111, and the other end is open. One end of the positioning spring 52 extends into the positioning sleeve 51, and the other end abuts on the positioning baffle 53. The positioning baffle 53 is fixed on the support 411. When the support 411 drives the elastic positioning assembly 5 to rotate, the positioning spring 52 will expand and contract with the conversion of the wave crest and the wave trough, so as to realize the free sliding of the positioning sleeve 51 between the wave crest and the wave trough.

[0055] Preferably, if Fig. 9 As shown, an anti-slip portion 4122 is provided on the circumferential side of the rotating portion 412. The provision of the anti-slip portion 4122 can improve the stability of the contact between the human hand and the switch knob, making it easier for the user to rotate the rotating component 4, thereby improving the user experience.

[0056] The operation process of the switch knob provided in this embodiment is as follows: the user rotates the rotating component 4, and the switch component 2 and the gear component 3 rotate accordingly, wherein the finger is always in contact with the touch ring 42. When the rotating component 4 rotates to a certain functional module, a coupling capacitor is formed in the gear component 3 and the corresponding functional module in the touch screen. At this time, the touch ring 42 is pressed, and the pressing portion 4121 at the bottom of the rotating portion 412 abuts against and presses the first pot piece 22, so that the first pot piece 22 is electrically connected to the second conductive portion 242 and then to the first conductive portion 241 and then to the touch screen. At this time, the finger is connected to the touch screen through the touch ring 42, the second spring 21, the contact sheet 23, the first pot piece 22 and the second conductive sheet 24 in sequence to form a coupling capacitor, and finally the corresponding functional module is confirmed.

[0057] This embodiment also provides a vehicle-mounted touch screen, which includes a touch screen body and the above-mentioned switch knob. The switch knob is detachably connected to the touch screen body. Without destroying the integrity of the touch screen body, the switch knob is installed on the touch screen body for use to select the function module of the touch screen, which can avoid the driver's attention being distracted by staring at the touch screen to operate, and realizes partial blind operation, thereby improving driving safety.

[0058] The above contents are only preferred embodiments of the present invention.
