Description

Technical Field

[0001] The utility model relates to the technical field of encoders, in particular to a multifunctional encoder knob button. Background Art

[0002] Rotary switch encoders are widely used in household appliances, instruments, automobiles, etc. Depending on the use and installation occasions, etc., their shapes and structures vary greatly.

[0003] In existing combined products of switches and encoders, there are mainly two combination methods for the buttons of the switch and the encoder knob: First, and also the more widely used one, the knob (i.e., the shaft core) and the button are the same component, and one component has two functions. When rotated, an encoding signal is generated, and when pressed, the switch is turned on. Second, the knob and the button are two independent components. Except for having a positional fit in assembly, they are independent in structure and use. Rotating the knob generates an encoding signal, and pressing the button activates the switch.

[0004] Compared with the first combination method, the second combination method has the advantage that the switch encoder can be made very thin, becoming a veritable thin-type switch encoder, especially suitable for use in remote controls to control fans, stereos, etc. However, the second combination method also has obvious deficiencies, that is, it is inconvenient to use. Because the knob and the button are two independent components, the knob is a turntable with a central hole, and the button is assembled in the central hole of the knob. The two are close to each other, so that when people use it, they must see the positions of the knob and the button. Generally, the button is located in the central hole and will not be pressed wrongly, and it can be pressed by feeling. When the button is located on the edge ring, when rotating the knob with one finger from the front of the knob, it is easy to touch the button, resulting in the dispersion of the force for rotating the knob and the tactile feeling, and rotating the button has no effect on the rotation of the knob, bringing a bad experience to the user and being not conducive to use. Content of the Utility Model

[0005] In view of the above deficiencies, the purpose of the utility model is to provide a multifunctional encoder knob button. Both rotating the knob and pressing the knob can generate encoding signals, and it can be used without identifying the button structure. Two methods are provided for users to choose, improving the practicability of this button. And this button has a compact structure, is relatively thin as a whole, occupies less space, and while ensuring stable conduction with the circuit board, it also has a good tactile feeling, improving the user experience.

[0010] As a further improvement of the present utility model, several coding recognition grooves are arranged on both the first knob conduction portion and the second knob conduction portion.

[0012] As a further improvement of the present utility model, at least one knob abutting arm extending downward to abut against the shaft code disc assembly is formed on the knob abutting piece, and a knob abutting bent pin, integrally in a V shape, is formed at the lowermost end of the knob abutting arm.

[0013] As a further improvement of the present utility model, there are three groups of the knob abutting arms, which respectively abut against the first knob conduction part, the second knob conduction part, and the third knob conduction part in one-to-one correspondence to achieve electrical connection.

[0014] As a further improvement of the present utility model, it further includes a tactile detent wheel sleeved on the outer side of the lower part of the shaft core, and a tactile spring piece arranged in the upper cover and pressing against the detent wheel; the knob abutting piece is fixed on the lower end surface of the tactile detent wheel.

After the lower end of the shaft encoder disk assembly penetrates through the base, it 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 shaft encoder disk assembly to achieve electrical connection. When people rotate the shaft core, the shaft core drives the knob contact piece to rotate on the shaft encoder disk assembly, causing the shaft encoder disk assembly to transmit an encoded signal to the external circuit board, realizing the corresponding signal output. People can also press down the shaft core, causing the shaft core to press against the dome switch. The originally upwardly bulging dome switch is pressed by the shaft core to be sunken downward and thus abuts against the shaft encoder disk assembly, causing the shaft encoder disk assembly to transmit an encoded signal to the external circuit board, realizing the corresponding signal output.

[0028] In order to further elaborate on the technical means and effects adopted by the present invention to achieve the predetermined purpose, the following combines the drawings and preferred embodiments to detail the specific implementation mode of the present invention.

[0029] In the description of the present invention, it should be understood that the orientation or positional relationship indicated by the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation to the present invention.

[0030] In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the present invention, "a plurality" means two or more unless otherwise specifically defined.

[0031] In the present utility model, unless otherwise clearly defined and limited, terms such as "installation", "connection", "linkage", "fixation", etc. shall be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral body; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, and it can be the communication inside two components or the interaction relationship between two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0032] Please refer to Figures 1 to 7 , an embodiment of the present utility model provides a multifunctional encoder knob button, which includes a base 1, an upper cover 2 arranged on the base 1, a shaft core 3 arranged between the base 1 and the upper cover 2 and penetrating through the upper cover 2, and further includes a dome switch 4 arranged on the base 1 and below the shaft core 3, a knob contact piece 5 arranged at the lower end of the shaft core 3, and an axial encoder disc assembly 6 annularly arranged outside the dome switch 4 and abutted by the knob contact piece 5 to achieve electrical connection. After the lower end of the axial encoder disc assembly 6 penetrates through the base 1, it abuts against an external circuit board 9 to achieve electrical connection; when the shaft core 3 is pressed down, the dome switch 4 deforms downward and abuts against the axial encoder disc assembly 6 to achieve electrical connection.

[0033] When people rotate the shaft core 3, the shaft core 3 drives the knob contact piece 5 to rotate on the axial encoder disc assembly 6, so that the axial encoder disc assembly 6 transmits an encoding signal to the external circuit board 9 to achieve corresponding signal output. People can also press down the shaft core 3, so that the shaft core 3 presses against the dome switch 4. The originally upwardly bulging dome switch 4 is pressed by the shaft core 3 to be depressed downward and thus abuts against the axial encoder disc assembly 6, so that the axial encoder disc assembly 6 transmits an encoding signal to the external circuit board 9 to achieve corresponding signal output. This button can be directly used without identifying the specific structure of the button. Two different button output methods are provided for users to choose, which improves the practicability of this button, meets the usage requirements of different users, and this button has a compact structure, is relatively thin as a whole, occupies less space, and while ensuring stable conduction with the circuit board 9, also has a good feel and improves the user experience.

[0034] For the installation method of this button, as Figure 1 shown, the machine that needs to install this button can be provided with a fixed steel plate 10 for the base 1 to be embedded. After the base 1 is snapped into the fixed steel plate 10, the axial encoder disc assembly 6 abuts against the circuit board 9 of this machine, thereby realizing signal transmission.

[0035] For the specific structural setting of the axial encoder disc assembly 6, as Figure 3 , Figures 5 to 6As shown, the shaft encoder disc assembly 6 includes a first button conduction sheet 61 directly below the middle of the dome sheet 4, a second button conduction sheet 62 disposed around the outside of the first button conduction sheet 61 and directly below the dome sheet 4, a first knob conduction sheet 63 disposed on one side of the second button conduction sheet 62 and capable of being abutted by the knob abutting sheet 5 to achieve electrical connection, a second knob conduction sheet 64 disposed on the other side of the second button conduction sheet 62 and capable of being abutted by the knob abutting sheet 5 to achieve electrical connection, and a third knob conduction sheet 65 disposed between the first knob conduction sheet 63 and the second knob conduction sheet 64 and capable of being abutted by the knob abutting sheet 5 to achieve electrical connection.

[0036] The lower ends of the first button conduction sheet 61 and the second button conduction sheet 62 are abutted against an external circuit board 9 to achieve electrical connection. When the dome sheet 4 is pressed by the shaft core 3, it is recessed downward, with its middle part pressing on the first button conduction sheet 61 and the outer ring of its lower end pressing on the second button conduction sheet 62, thereby respectively corresponding to conduction with the first button conduction sheet 61 and the second button conduction sheet 62, and electrically connecting with the external circuit board 9 through the first button conduction sheet 61 and the second button conduction sheet 62 to transmit encoded signals, achieving corresponding signal output, and the conduction is stable.

[0037] The lower ends of the first knob conduction sheet 63, the second knob conduction sheet 64, and the third knob conduction sheet 65 are abutted against the external circuit board 9 to achieve electrical connection. The lower end of the knob abutting sheet 5 respectively presses on the first knob conduction sheet 63, the second knob conduction sheet 64, and the third knob conduction sheet 65. When the shaft core 3 drives the knob abutting sheet 5 to rotate, the knob abutting sheet 5 respectively rotates on the first knob conduction sheet 63, the second knob conduction sheet 64, and the third knob conduction sheet 65, thereby being respectively sensed by the first knob conduction sheet 63, the second knob conduction sheet 64, and the third knob conduction sheet 65, and electrically connecting with the external circuit board 9 through the first knob conduction sheet 63, the second knob conduction sheet 64, and the third knob conduction sheet 65 to transmit encoded signals, achieving corresponding signal output, and the conduction is stable. By basically setting the structure of the shaft encoder disc assembly 6 as a structure ring disposed on another structure, the shaft encoder has a compact structure, is relatively thin as a whole, occupies less space, reduces the overall occupied area of this button while ensuring stable conduction with the circuit board 9, and makes this button more practical.

[0038] Regarding the specific structural setting of the first button conduction sheet 61, such as Figure 3 、 Figures 5 to 6As shown, the first button conduction piece 61 includes a first button conduction part 611 horizontally arranged below the middle of the dome sheet 4, and a first button conduction pin 612 integrally arranged at the outer end of the first button conduction part 611 and bent and extended inward and downward. When the middle part of the dome sheet 4 is pressed downward by the shaft core 3 and sinks, it abuts on the first button conduction part 611. The bent tail end of the first button conduction pin 612 abuts on the external circuit board 9, so as to realize the conduction connection of the first button conduction piece 61, and further transmit the encoded signal to the external circuit board 9 to realize the corresponding signal output. By setting the first button conduction pin 612 to have a structure with its lower end bent and extended inward and downward, 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 first button conduction pin 612 can stably abut on the circuit board 9, realize the conduction with the circuit board 9 and the corresponding signal output, meet the requirements of different heights of the fixed steel plate 10 and the circuit board 9, and improve the applicability of this button.

[0039] For the specific structural setting of the second button conduction piece 62, as Figure 3 , Figures 5 to 6 As shown, the second button conduction piece 62 includes a second button conduction part 621 annularly arranged outside the first button conduction part 611 and directly below the dome sheet 4, and a second button conduction pin 622 integrally arranged at the outer end of the second button conduction part 621 and bent and extended inward and downward. When the outer side of the dome sheet 4 is pressed downward by the shaft core 3 and sinks, it abuts on the second button conduction part 621. The bent tail end of the second button conduction pin 622 abuts on the external circuit board 9, so as to realize the conduction connection of the second button conduction piece 62, and further transmit the encoded signal to the external circuit board 9 to realize the corresponding model output. By setting the second button conduction pin 622 to have a structure with its lower end bent and extended inward and downward, 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 stably abut on the circuit board 9, realize the conduction with the circuit board 9 and the corresponding signal output, meet the requirements of different heights of the fixed steel plate 10 and the circuit board 9, and improve the applicability of this button.

[0040] For the specific structural setting of the first knob conduction piece 63, as Figure 3 , Figures 5 to 6As shown, the first knob conduction piece 63 includes a first knob conduction portion 631 disposed on one side of the second button conduction piece 62 and capable of being abutted by the knob abutting piece 5 to achieve electrical connection, and a first knob conduction pin 632 integrally disposed at the outer end of the first knob conduction portion 631 and bent and extended inward and downward. By setting the first knob conduction pin 632 to have a structure with its lower end bent and extended 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 conduction pin 632 can be stably pressed against the circuit board 9, realizing conduction with the circuit board 9 and corresponding signal output, meeting the requirements of different heights of the fixing steel plate 10 and the circuit board 9, and improving the applicability of this button.

[0041] Regarding the specific structural setting of the second knob conduction piece 64, as Figure 3 , Figures 5 to 6 shown, the second knob conduction piece 64 includes a second knob conduction portion 641 disposed on the other side of the second button conduction piece 62 and capable of being abutted by the knob abutting piece 5 to achieve electrical connection, and a second knob conduction pin 642 integrally disposed at the outer end of the second knob conduction portion 641 and bent and extended inward and downward. By setting the second knob conduction pin 642 to have a structure with its lower end bent and extended 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 conduction pin 642 can be stably pressed against the circuit board 9, realizing conduction with the circuit board 9 and corresponding signal output, meeting the requirements of different heights of the fixing steel plate 10 and the circuit board 9, and improving the applicability of this button.

[0042] Regarding the specific structural setting of the third knob conduction piece 65, as Figure 3 , Figures 5 to 6 shown, the third knob conduction piece 65 includes a third knob conduction portion 651 disposed between the first knob conduction piece 63 and the second knob conduction piece 64 and capable of being abutted by the knob abutting piece 5 to achieve electrical connection, and a third knob conduction pin 652 integrally disposed at the outer end of the third knob conduction portion 651 and bent and extended inward and downward. By setting the third knob conduction pin 652 to have a structure with its lower end bent and extended 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 conduction pin 652 can be stably pressed against the circuit board 9, realizing conduction with the circuit board 9 and corresponding signal output, meeting the requirements of different heights of the fixing steel plate 10 and the circuit board 9, and improving the applicability of this button.

[0043] Regarding the specific manner in which the shaft encoder disk assembly 6 is recognized by the knob abutting piece 5, as Figure 3 ,Figures 5 to 6 As shown, several coding recognition slots 66 are arranged on both the first knob conduction part 631 and the second knob conduction part 641. By setting the coding recognition slots 66 for conducting terminals, when the knob contact piece 5 rotates and abuts on the first knob conduction part 631 and the second knob conduction part 641, the amplitude of the rotation of the shaft core 3 can be recognized by passing through a certain number of groups of coding recognition slots 66, so as to realize corresponding signal output.

[0044] Regarding the specific way in which the knob contact piece 5 abuts on the shaft code disk assembly 6, such as Figure 3 、 Figure 6 As shown, at least one knob contact arm 51 extending downward to abut on the shaft code disk assembly 6 is formed on the knob contact piece 5, and a knob contact bending pin 52 with an overall V-shaped structure is formed at the lowermost end of the knob contact arm. When the user rotates the shaft core 3, the shaft core 3 drives the knob contact piece 5 arranged thereon to rotate synchronously, so that the knob contact arm 51 thereon drives the knob contact bending pin 52 to rotate on the shaft code disk assembly 6, so that the knob contact bending pin 52 contacts 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 shaft code disk assembly 6 and recognizes the amplitude of the rotation of the shaft core 3 by passing through the coding recognition slots 66 at intervals, so as to realize corresponding signal output. By setting the knob contact bending pin 52 to have an overall V-shaped structure, the knob contact bending pin 52 can abut more stably, and the inclined guide surface formed by its V-shaped structure also guides itself back to the first knob conduction part 631 or the second knob conduction part 641 to realize conduction when passing through the coding recognition slots 66, preventing the problem that the knob contact bending pin 52 cannot return to the first knob conduction part 631 or the second knob conduction part 641 after passing through the coding recognition slots 66, resulting in abnormal conduction.

[0045] Preferably, such as Figure 3 、 Figure 6As shown, there are three groups of the knob contact arms 51, which are respectively in one-to-one correspondence with the first knob conduction part 631, the second knob conduction part 641, and the third knob conduction part 651 for abutting to achieve electrical connection. Correspondingly, there are also 3 groups of the knob contact bending pins 52. Specifically, when the shaft core 3 drives the knob contact piece 5 to rotate, the first group of knob contact arms 51 drives the knob contact bending pins 52 thereon to rotate and abut on the first knob conduction part 631, and the rotation amplitude of the shaft core 3 can be known through the coding recognition slots 66 on the spaced first knob conduction part 631. The second knob contact arm 51 drives the knob contact bending pins 52 thereon to rotate and abut on the second knob conduction part 641, and the rotation amplitude of the shaft core 3 can be known through the coding recognition slots 66 on the spaced second knob conduction part 641. The two cooperate with each other, so that the signal transmitted by this button is more accurate and the sensing accuracy of this button is improved. The third group of knob contact arms 51 drives the knob contact bending pins 52 thereon to rotate and abut on the third knob conduction part 651 to achieve stable signal output of the third knob conduction piece 65.

[0046] In order to make the shaft code disk assembly 6 conduct better with the external circuit board 9, as Figures 1 to 4 shown, at the lower part of the tails 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, guiding contact points 67 which are integrally semicircular are formed. By setting the guiding contact points 67 to be semicircular, their areas are larger, and they can contact and conduct with the circuit board 9 better, thereby improving the conduction efficiency of this button and ensuring the normal operation of this button.

[0047] Preferably, as Figure 1 and Figure 2 shown, the base 1 is further provided with positioning posts 11 extending downward, and the circuit board 9 is provided with positioning holes 91 matching the positioning posts 11. When installing this button, the positioning posts 11 can be aligned with the positioning holes 91 and inserted, so as to achieve the purpose of fixing this button on the circuit board 9, and prevent the problem that 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 displaced from the circuit board during the use of this button, resulting in signal failure to be transmitted.

[0048] For the specific manner in which 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 abut on the circuit board 9, as Figures 1 to 4As shown, five sets of contact pieces 92 are provided on the circuit board 9, which are electrically connected to 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. The guiding contact points 67 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 respectively abut against the contact pieces 92 one by one to achieve signal conduction.

[0049] Preferably, in order to make the shaft core 3 better press against the dome switch 4 to cause the dome switch 4 to deform, as Figure 7 shown, a pressing semi-cylindrical platform 31, which is integrally semi-circular and convex downward, is formed at the lower end of the shaft core 3. The semi-circular shape has a larger area, so that the pressing semi-cylindrical platform 31 can better and more accurately press against the dome switch 4 to cause the dome switch 4 to deform, improving the conduction efficiency of the button press.

[0050] In order to make the feel of the button rotation better, as Figures 2 to 3 shown, the button further includes a feel stop wheel 7 sleeved on the outer side of the lower part of the shaft core 3, and a feel spring piece 8 arranged in the upper cover 2 and pressing against the stop wheel. The knob contact piece 5 is fixed to the lower end surface of the feel stop wheel 7. When the user rotates the shaft core 3, the feel stop wheel 7 is driven by the shaft core 3 to rotate synchronously, so that the feel spring piece 8 makes a relative movement on the feel stop wheel 7, thereby generating a feel of rotation and making the user's experience better.

[0051] For the specific way of generating the feel of the feel stop wheel 7, as Figures 2 to 3 shown, several feel convex ridges 71 protruding upward are evenly arranged on the upper end surface of the feel stop wheel 7. A feel contact piece 81 that extends downward obliquely and presses against the feel convex ridges 71 is symmetrically arranged inside the feel spring piece 8. The array of upward protruding feel convex ridges 71 forms a wavy structure. When the feel stop wheel 7 rotates, the feel contact piece 81 makes a relative movement with respect to the feel stop wheel 7. The feel contact piece 81 rotates on the array of wavy feel convex ridges 71 and is lifted by the feel convex ridges 71 and descends between two groups of feel convex ridges 71, forming a sense of jerk, thereby bringing a better feel to the user and making the user's experience better.

[0052] Preferably, in order to make the feel contact piece 81 better abut and rotate on the feel stop wheel 7, as Figures 2 to 3As shown, a tactile contact portion 82 that is bent downward in an arc shape is formed in the middle of the tactile contact piece 81. By setting the tactile contact portion 82 to have a downward arc-shaped bending structure, the area of contact between the tactile contact portion 82 and the tactile convex rib 71 is larger, and the semi-circular arc structure has a guiding property, making it easier to come into contact with the tactile convex rib 71. Thereby, the accuracy of the tactile contact piece 81 against the tactile detent wheel 7 is improved, making the rotational tactile feeling of this button more obvious, and further enhancing the user experience.

[0053] It should be noted here that the multi-functional encoder knob button disclosed in the present utility model is an improvement on the specific structure, and the specific control method is not the innovation point of the present utility model.
