Description

A multi-functional encoder knob button Technical Field

[0001] This utility model relates to the field of encoder technology, and in particular to a multifunctional encoder knob button. Background Technology

[0002] Rotary switch encoders are widely used in home appliances, instruments, automobiles, and other fields. Their shape and structure vary considerably depending on the application and installation location.

[0003] Existing switch-encoder combination products mainly employ two methods for combining the switch button and encoder knob: The first, and more widely used, method involves the knob (i.e., the shaft) and the button being a single component, performing two functions: rotating it generates an encoding signal, and pressing it activates the switch. The second method treats the knob and button as two independent components. Aside from a positional fit during assembly, their structure and operation are separate; rotating the knob generates an encoding signal, and pressing the button activates the switch.

[0004] The second combination method, compared to the first, has the advantage of allowing the switch encoder to be made very thin, becoming a truly thin switch encoder, especially suitable for remote control applications, such as controlling fans and speakers. However, the second combination method also has a significant drawback: inconvenience in use. Because the knob and button are two separate components—the knob is a dial with a central hole, and the button is mounted in the same central hole—their proximity forces users to carefully observe their positions. Normally, the button, located in the central hole, is easy to press by feel. However, the button, located on the edge, is easily touched when rotating the knob with a single finger from the front, causing the force and feel of rotating the knob to be dispersed. Rotating the button has no effect on the knob's rotation, resulting in a poor user experience and hindering usability. Utility Model Content

[0005] To address the aforementioned shortcomings, the purpose of this utility model is to provide a multifunctional encoder knob button. Both rotating and pressing the knob can generate encoded signals, and it can be used without recognizing the button structure. The two methods are available for users to choose from, which improves the practicality of the button. Furthermore, the button has a compact structure, is relatively thin, and occupies little space. While ensuring stable conduction with the circuit board, it also has a good tactile feel, improving the user experience.

[0006] The technical solution adopted by this utility model to achieve the above objectives is as follows:

[0007] A multifunctional encoder knob includes a base, a top cover disposed on the base, a shaft core disposed between the base and the top cover and extending through the top cover, a dome switch disposed on the base and located below the shaft core, a knob abutment disposed at the lower end of the shaft core, and a code disk assembly disposed around the outside of the dome switch and abutted by the knob abutment to achieve electrical connection. The lower end of the code disk assembly extends through the base and abuts against an external circuit board to achieve electrical connection. When the shaft core is pressed down, the dome switch deforms downward and abuts against the code disk assembly to achieve electrical connection.

[0008] As a further improvement of this utility model, the axis code disk assembly includes a first button conductive piece located directly below the center of the dome switch, a second button conductive piece arranged around the outside of the first button conductive piece and located directly below the dome switch, a first knob conductive piece disposed on one side of the second button conductive piece and electrically connected by a knob contact piece, a second knob conductive piece disposed on the other side of the second button conductive piece and electrically connected by a knob contact piece, and a third knob conductive piece disposed between the first and second knob conductive pieces and electrically connected by a knob contact piece.

[0009] As a further improvement of this utility model, the first button conductive piece includes a first button conductive portion horizontally disposed below the center of the dome switch, and a first button conductive pin integrally disposed at the outward end of the first button conductive portion and bent inward and downward; the second button conductive piece includes a second button conductive portion surrounding the outside of the first button conductive portion and located directly below the dome switch, and a second button conductive pin integrally disposed at the outward end of the second button conductive portion and bent inward and downward; the first knob conductive piece includes a first knob conductive portion disposed on one side of the second button conductive piece and abutted by a knob contact piece to achieve electrical connection, and a The first knob conductive pin is integrally disposed at the outward end of the first knob conductive portion and extends inward and downward; the second knob conductive piece includes a second knob conductive portion disposed on the other side of the second knob conductive piece and which can be abutted by the knob abutment to achieve electrical connection, and a second knob conductive pin integrally disposed at the outward end of the second knob conductive portion and extends inward and downward; the third knob conductive piece includes a third knob conductive portion disposed between the first knob conductive piece and the second knob conductive piece and which can be abutted by the knob abutment to achieve electrical connection, and a third knob conductive pin integrally disposed at the outward end of the third knob conductive portion and extends inward and downward.

[0010] As a further improvement of this utility model, several coding identification slots are arranged on both the first knob conduction part and the second knob conduction part.

[0011] As a further improvement of this utility model, the lower part of the tail end of the first button conduction pin, the second button conduction pin, the first knob conduction pin, the second knob conduction pin, and the third knob conduction pin are all formed with a guide contact point that is generally semi-circular in shape.

[0012] As a further improvement of this utility model, at least one knob abutment arm is formed on the knob abutment plate, extending downward to abut against the axis code disk assembly, and a knob abutment bending pin with an overall V shape is formed at the lowest end of the knob abutment wall.

[0013] As a further improvement of this utility model, the knob contact arm is in three sets, which respectively contact the first knob conducting part, the second knob conducting part and the third knob conducting part to achieve electrical connection.

[0014] As a further improvement of this utility model, it also includes a tactile stop wheel sleeved on the outer side of the lower part of the shaft core, and a tactile spring piece disposed inside the upper cover and pressing against the stop wheel; the knob contact piece is fixed to the lower end surface of the tactile stop wheel.

[0015] As a further improvement of this utility model, several upwardly protruding tactile ridges are evenly arranged on the upper surface of the tactile stop wheel, and a tactile abutment piece is symmetrically arranged on the inner side of the tactile spring sheet, extending downwardly to press against the tactile ridges.

[0016] As a further improvement of this utility model, the tactile contact piece has a tactile contact portion that is bent downward in an arc shape in the middle.

[0017] The beneficial effects of this utility model are as follows:

[0018] This button is configured to include a base, a top cover on the base, and a shaft extending through the top cover and between the base and the top cover. It also includes a dome switch on the base and below the shaft, a knob contact at the lower end of the shaft, and a code disk assembly surrounding the dome switch and contacted by the knob contact for electrical connection. The lower end of the code disk assembly extends through the base and contacts an external circuit board for electrical connection. When the shaft is pressed down, the dome switch deforms downwards and contacts the code disk assembly for electrical connection. When the shaft is rotated, it causes the knob contact to rotate on the code disk assembly, which transmits coded signals to the external circuit board, resulting in corresponding signal output. Users can also press down on the shaft core, causing it to press against the dome switch. The dome switch, which was originally bulging upwards, is now concave, contacting the code disk assembly. This allows the code disk assembly to transmit encoded signals to the external circuit board, achieving the corresponding signal output. This button can be used directly without needing to identify its specific structure. Two different button output methods are available for users to choose from, improving the button's practicality and meeting the needs of different users. Furthermore, this button has a compact structure, is relatively thin, and occupies little space. While ensuring stable conduction with the circuit board, it also has a good tactile feel, improving the user experience.

[0028] Detailed Implementation

[0029] To further illustrate the technical means and effects adopted by this utility model to achieve its intended purpose, the specific implementation methods of this utility model will be described in detail below with reference to the accompanying drawings and preferred embodiments.

[0030] In the description of this utility model, it should be understood that the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0031] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0032] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0033] Referring to Figures 1 to 7, this embodiment of the utility model provides a multifunctional encoder knob button, including a base 1, an upper cover 2 disposed on the base 1, a shaft core 3 disposed between the base 1 and the upper cover 2 and extending through the upper cover 2, and also including a dome switch 4 disposed on the base 1 and located below the shaft core 3, a knob contact piece 5 disposed at the lower end of the shaft core 3, and a code disk assembly 6 disposed around the outside of the dome switch 4 and abutted by the knob contact piece 5 to achieve electrical connection. The lower end of the code disk assembly 6 extends through the base 1 and abuts against an external circuit board 9 to achieve electrical connection; the dome switch 4 deforms downward when the shaft core 3 is pressed down to abut against the code disk assembly 6 to achieve electrical connection.

[0034] When the shaft core 3 is rotated, it drives the knob contact piece 5 to rotate on the axis code disk assembly 6, causing the axis code disk assembly 6 to transmit encoded signals to the external circuit board 9, thus achieving the corresponding signal output. Alternatively, the user can press down on the shaft core 3, causing it to press against the dome switch 4. The dome switch 4, which was originally bulging upwards, is now pressed downwards by the shaft core 3, thus contacting the axis code disk assembly 6. This allows the axis code disk assembly 6 to transmit encoded signals to the external circuit board 9, achieving the corresponding signal output. This button can be used directly without needing to identify its specific structure. Two different button output methods are available for users to choose from, improving the button's practicality and meeting the needs of different users. Furthermore, the button has a compact structure, is relatively thin, and occupies little space. While ensuring stable conduction with the circuit board 9, it also provides a good tactile feel, improving the user experience.

[0035] As shown in Figure 1, the machine to which this button is installed may be provided with a fixed steel plate 10 for the base 1 to be embedded. After the base 1 is inserted into the fixed steel plate 10, the axis code disk assembly 6 abuts against the circuit board 9 of the machine, thereby realizing the transmission of signals.

[0036] As shown in Figures 3, 5 and 6, the specific structural configuration of the axis code disk assembly 6 includes a first button conductive piece 61 located directly below the center of the dome switch 4, a second button conductive piece 62 surrounding the outside of the first button conductive piece 61 and located directly below the dome switch 4, a first knob conductive piece 63 disposed on one side of the second button conductive piece 62 and electrically connected by a knob contact piece 5, a second knob conductive piece 64 disposed on the other side of the second button conductive piece 62 and electrically connected by a knob contact piece 5, and a third knob conductive piece 65 disposed between the first knob conductive piece 63 and the second knob conductive piece 64 and electrically connected by a knob contact piece 5.

[0037] The lower ends of the first button conductive piece 61 and the second button conductive piece 62 abut against the external circuit board 9 to achieve electrical connection. When the dome switch 4 is pressed by the shaft core 3, it is recessed downward, with its middle part pressing against the first button conductive piece 61 and its lower outer ring pressing against the second button conductive piece 62, thereby correspondingly conducting with the first button conductive piece 61 and the second button conductive piece 62 respectively. It is electrically connected to the external circuit board 9 through the first button conductive piece 61 and the second button conductive piece 62 to transmit encoded signals, realize the corresponding signal output, and the conduction is stable.

[0038] The lower ends of the first knob contact piece 63, the second knob contact piece 64, and the third knob contact piece 65 abut against the external circuit board 9 to achieve electrical connection. The lower ends of the knob contact pieces 5 press against the first knob contact piece 63, the second knob contact piece 64, and the third knob contact piece 65 respectively. When the shaft core 3 drives the knob contact pieces 5 to rotate, the knob contact pieces 5 rotate on the first knob contact piece 63, the second knob contact piece 64, and the third knob contact piece 65 respectively, thereby being sensed by the first knob contact piece 63, the second knob contact piece 64, and the third knob contact piece 65 respectively, and are electrically connected to the external circuit board 9 through the first knob contact piece 63, the second knob contact piece 64, and the third knob contact piece 65 to transmit encoded signals, realize the corresponding signal output, and the conduction is stable. By essentially setting the structure of the axis code disk assembly 6 as one structure ring on another, the axis code disk structure is compact, thin, and occupies less space. While ensuring stable conduction with the circuit board 9, it reduces the overall area occupied by the button, making the button more practical.

[0039] As shown in Figures 3, 5 and 6, the first button conductive piece 61 includes a first button conductive part 611 horizontally disposed below the middle of the dome switch 4, and a first button conductive pin 612 integrally disposed at the outward end of the first button conductive part 611 and bent inward and downward. When the middle part of the dome switch 4 is pressed downward by the shaft core 3, it abuts against the first button conductive part 611. The bent tail end of the first button conductive pin 612 abuts against the external circuit board 9, thereby realizing the conductive connection of the first button conductive piece 61, and then transmitting the encoded signal to the external circuit board 9 to realize the corresponding signal output. By setting the first button conduction pin 612 to a structure that bends inward and downward at the lower end, it can be elastically bent according to the height between the fixing steel plate 10 and the circuit board 9 during the installation of this button, so that the first button conduction pin 612 can be stably pressed against the circuit board 9, realizing conduction with the circuit board 9 and corresponding signal output, meeting the needs of different fixing steel plates 10 and circuit boards 9 heights, and improving the applicability of this button.

[0040] As shown in Figures 3, 5, and 6, the second button conductive piece 62 includes a second button conductive part 621 surrounding the first button conductive part 611 and located directly below the dome switch 4, and a second button conductive pin 622 integrally disposed at the outward end of the second button conductive part 621 and bent inward and downward. When the outer side of the dome switch 4 is pressed downward by the shaft core 3, it abuts against the second button conductive part 621. The bent tail end of the second button conductive pin 622 abuts against the external circuit board 9, thereby realizing the conductive connection of the second button conductive piece 62, and then transmitting the encoded signal to the external circuit board 9 to realize the corresponding model output. By setting the second button conduction pin 622 to a structure that bends inward and downward at the lower end, it can be elastically bent according to the height between the fixed steel plate 10 and the circuit board 9 during the installation of this button, so that the second button conduction pin 622 can be stably pressed against the circuit board 9, realizing conduction with the circuit board 9 and corresponding signal output, meeting the needs of different fixed steel plates 10 and circuit boards 9 heights, and improving the applicability of this button.

[0041] As shown in Figures 3, 5, and 6, the first knob conductive piece 63 includes a first knob conductive part 631 disposed on one side of the second button conductive piece 62 and abutted by the knob abutment piece 5 to achieve electrical connection, and a first knob conductive pin 632 integrally disposed on the outward end of the first knob conductive part 631 and bent inward and downward. By setting the first knob conductive pin 632 to a structure with its lower end bent inward and downward, it can be elastically bent according to the height between the fixing steel plate 10 and the circuit board 9 during the installation of this button, so that the first knob conductive pin 632 can be stably pressed against the circuit board 9, realizing conduction with the circuit board 9 and corresponding signal output, meeting the needs of different fixing steel plates 10 and circuit boards 9 heights, and improving the applicability of this button.

[0042] As shown in Figures 3, 5, and 6, the second knob conductive piece 64 includes a second knob conductive portion 641 disposed on the other side of the second button conductive piece 62 and abutted by the knob abutment piece 5 to achieve electrical connection, and a second knob conductive pin 642 integrally disposed on the outward end of the second knob conductive portion 641 and bent inward and downward. By setting the second knob conductive pin 642 to a structure with its lower end bent inward and downward, it can be elastically bent according to the height between the fixing steel plate 10 and the circuit board 9 during the installation of this button, so that the second knob conductive pin 642 can be stably pressed against the circuit board 9, realizing conduction with the circuit board 9 and corresponding signal output, meeting the needs of different fixing steel plates 10 and circuit boards 9 heights, and improving the applicability of this button.

[0043] As shown in Figures 3, 5, and 6, the third knob conductive piece 65 includes a third knob conductive portion 651 disposed between the first knob conductive piece 63 and the second knob conductive piece 64 and electrically connected by a knob abutment piece 5, and a third knob conductive pin 652 integrally disposed at the outward end of the third knob conductive portion 651 and bent inward and downward. By setting the third knob conductive pin 652 to a structure with its lower end bent inward and downward, it can be elastically bent according to the height between the fixing steel plate 10 and the circuit board 9 during the installation of this button, so that the third knob conductive pin 652 can be stably pressed against the circuit board 9, realizing conduction with the circuit board 9 and corresponding signal output, meeting the needs of different fixing steel plates 10 and circuit boards 9 heights, and improving the applicability of this button.

[0044] As shown in Figures 3, 5 and 6, the first knob conducting part 631 and the second knob conducting part 641 are each provided with a number of coding identification slots 66. By setting the coding identification slots 66 as the conducting terminals, when the knob abutment 5 rotates and abuts on the first knob conducting part 631 and the second knob conducting part 641, the amplitude of the rotation of the shaft core 3 can be identified by how many sets of coding identification slots 66 it passes through, thereby realizing the corresponding signal output.

[0045] As shown in Figures 3 and 6, the knob contact piece 5 abuts against the axis code disk assembly 6. At least one knob contact arm 51 extends downwards to abut against the axis code disk assembly 6. The lowest end of the knob contact wall forms a V-shaped knob contact bent pin 52. When the user rotates the shaft core 3, the shaft core 3 drives the knob contact piece 5 mounted thereon to rotate synchronously. This causes the knob contact arm 51 to drive the knob contact bent pin 52 to rotate on the axis code disk assembly 6. This allows the knob contact bent pin 52 to contact the corresponding structures of the first knob conduction part 631, the second knob conduction part 641, and the third knob conduction part 651 on the axis code disk assembly 6. The rotation amplitude of the shaft core 3 is then detected through the coding recognition slot 66 at intervals, thereby achieving the corresponding signal output. By setting the knob contact bending pin 52 to an overall V-shaped structure, the contact of the knob contact bending pin 52 is made more stable. Furthermore, the inclined guide surface formed by its V-shaped structure guides itself back to the first knob conduction part 631 or the second knob conduction part 641 when passing through the code identification slot 66, thus achieving conduction. This prevents the knob contact bending pin 52 from failing to return to the first knob conduction part 631 or the second knob conduction part 641 after passing through the code identification slot 66, which would otherwise result in a failure to conduct properly.

[0046] Preferably, as shown in Figures 3 and 6, the knob contact arms 51 are in three groups, which respectively contact the first knob conducting part 631, the second knob conducting part 641 and the third knob conducting part 651 to achieve electrical connection. The knob contact bending pins 52 are also in three groups. Specifically, when the shaft core 3 drives the knob contact piece 5 to rotate, the first set of knob contact arms 51 drives the knob contact bending pin 52 on it to rotate and abut against the first knob conduction part 631. The rotation amplitude of the shaft core 3 is known through the coded identification groove 66 on the spaced first knob conduction part 631. The second set of knob contact arms 51 drives the knob contact bending pin 52 on it to rotate and abut against the second knob conduction part 641. The rotation amplitude of the shaft core 3 is also known through the coded identification groove 66 on the spaced second knob conduction part 641. The two work together to make the signal transmitted by this button more accurate and improve the sensing accuracy of this button. The third set of knob contact arms 51 drives the knob contact bending pin 52 on it to rotate and abut against the third knob conduction part 651, realizing a stable signal output of the third knob conduction piece 65.

[0047] To improve the conductivity between the axis code disk assembly 6 and the external circuit board 9, as shown in Figures 1 to 4, the lower end of the tail of the first button conduction pin 612, the second button conduction pin 622, the first knob conduction pin 632, the second knob conduction pin 642, and the third knob conduction pin 652 are all formed with a semi-circular guiding contact point 67. By setting the guiding contact point 67 to a semi-circular shape, its area is larger, which can better contact the circuit board 9 for conduction, thereby improving the conduction efficiency of the button and ensuring the normal operation of the button.

[0048] Preferably, as shown in Figures 1 and 2, the base 1 is further provided with a downwardly extending positioning post 11, and the circuit board 9 is provided with a positioning hole 91 that matches the positioning post 11. When installing this button, it can be inserted by aligning the positioning post 11 with the positioning hole 91, thereby achieving the purpose of fixing this button on the circuit board 9. This prevents the button from shifting off the circuit board 9 during use, which would cause the first button conduction pin 612, the second button conduction pin 622, the first knob conduction pin 632, the second knob conduction pin 642, and the third knob conduction pin 652 to shift off the circuit board, resulting in the inability to transmit signals.

[0049] The specific manner in which the first button-on pin 612, the second button-on pin 622, the first knob-on pin 632, the second knob-on pin 642, and the third knob-on pin 652 abut against the circuit board 9 is shown in Figures 1 to 4. The circuit board 9 is provided with five sets of contact pieces 92 that correspond to the first button-on pin 612, the second button-on pin 622, the first knob-on pin 632, the second knob-on pin 642, and the third knob-on pin 652. The guiding contact points 67 of the first button-on pin 612, the second button-on pin 622, the first knob-on pin 632, the second knob-on pin 642, and the third knob-on pin 652 abut against the contact pieces 92 one by one to achieve signal conduction.

[0050] Preferably, in order to better press the shaft core 3 against the dome switch 4 and cause the dome switch 4 to deform, as shown in Figure 7, the lower end of the shaft core 3 is formed with a semi-circular and downwardly protruding pressing semi-circular platform 31. The semi-circular shape has a larger area, so that the pressing semi-circular platform 31 can better and more accurately press against the dome switch 4 and cause the dome switch 4 to deform, thereby improving the conduction efficiency of the button press.

[0051] To improve the tactile feedback of the button, as shown in Figures 2 and 3, the button further includes a tactile stop wheel 7 sleeved on the lower outer side of the shaft core 3, and a tactile spring 8 disposed inside the upper cover 2 and pressing against the stop wheel. The knob contact piece 5 is fixed to the lower end face of the tactile stop wheel 7. When the user rotates the shaft core 3, the tactile stop wheel 7 is driven to rotate synchronously by the shaft core 3, thereby causing the tactile spring 8 to move relative to the tactile stop wheel 7, thus producing a tactile feedback and improving the user experience.

[0052] As shown in Figures 2 and 3, the tactile feedback mechanism of the tactile stop wheel 7 is achieved by uniformly arranging several upward-protruding tactile ridges 71 on its upper surface. A tactile abutment piece 81, extending downwards and pressing against the tactile ridges 71, is symmetrically arranged on the inner side of the tactile spring piece 8. The array of upward-protruding tactile ridges 71 forms a wave-like structure. When the tactile stop wheel 7 rotates, the tactile abutment piece 81 moves relative to the tactile stop wheel 7. The tactile abutment piece 81 rotates on the wave-shaped array of tactile ridges 71, is lifted by the ridges 71, and descends between two sets of tactile ridges 71, creating a tactile feedback that provides a better tactile feel and enhances the user experience.

[0053] Preferably, in order to better abut against the tactile abutment 81 and rotate on the tactile stop wheel 7, as shown in Figures 2 and 3, a tactile abutment portion 82 with a downward arc bend is formed in the middle of the tactile abutment 81. By setting the tactile abutment portion 82 to a downward arc bend, the contact area between the tactile abutment portion 82 and the tactile protrusion 71 is larger, and the semi-arc structure has a guiding function, making it easier to contact the tactile protrusion 71. This improves the accuracy of the tactile abutment 81 against the tactile stop wheel 7, makes the rotation feel of the button more obvious, and thus improves the user experience.

[0054] It should be noted that the multifunctional encoder knob and button disclosed in this utility model is an improvement on the specific structure, but the specific control method is not the innovation of this utility model. The circuit board, fixing steel plate, top cover, shaft core, base, and other components involved in this utility model can be general standard parts or components known to those skilled in the art. Their structure, principle, and control method are all known to those skilled in the art through technical manuals or conventional experimental methods.

[0055] The above description is merely a preferred embodiment of the present utility model and does not constitute any limitation on the technical scope of the present utility model. Therefore, other structures obtained by using the same or similar technical features as the above embodiments of the present utility model are all within the protection scope of the present utility model.
