Description

Technical Field

[0001] The utility model relates to a rotary switch, in particular to a rotary switch with a pressing mechanism. Background Art

[0002] Modern touch screens are mostly combined with virtual knobs, allowing users to draw circles with their fingers to rotate the virtual knobs, thereby achieving the control of the display screen switching of the touch screen. However, in some industrial applications, in order to avoid problems such as easy touch interruption or mistakes of virtual knobs, physical knobs are still used to replace virtual knobs and thus integrated with the touch screen.

[0003] However, if the physical knob integrated on the touch screen can only perform a rotating action, when pressing an option, the user's finger needs to leave the physical knob to touch the option displayed on the touch screen, or the finger of the other hand needs to be freed to touch the option displayed on the touch screen, which makes the user feel inconvenient to operate.

[0004] Therefore, how to design a physical knob that can be integrated on the touch screen to have a pressing function, and the assembly structure of this physical knob has the advantages of being simpler, more stable and cost-saving, etc., is the key point jointly researched and developed by knob manufacturers.

[0005] In view of this, the inventor of the present invention specifically studied hard and combined with the application of theory for the above-mentioned existing technologies, and tried his best to solve the above problems, which became the goal of the inventor's improvement. Summary of the Utility Model

[0006] The utility model provides a rotary switch with a pressing mechanism. When the outer cover is pressed and descends relative to the fixed base, it will drive the outer cover to abut against the conductive shaft rod, so as to achieve the function that the rotary switch has pressing and touching.

[0007] In an embodiment of the present utility model, the present utility model provides a rotary knob switch with a pressing mechanism, comprising: a fixed base having a bottom plate; a rotatable cover including an outer cover rotatably and liftably assembled above the fixed base and an inner cover sandwiched between the fixed base and the outer cover and rotating with the outer cover, the inner cover being provided with a perforation configured corresponding to the outer cover and a first setting portion configured corresponding to the bottom plate; a conductive shaft rod movably passing through the perforation, the conductive shaft rod having a second setting portion configured corresponding to the bottom plate; an elastic element elastically supporting between the outer cover and the conductive shaft rod and pushing to form a spacing between the conductive shaft rod and the outer cover; and a touch control assembly including a first touch pad, a second touch pad, a first connecting member and a second connecting member, the first connecting member connecting the first setting portion and the first touch pad and pushing the first touch pad to abut against the bottom plate, the second connecting member connecting the second setting portion and the second touch pad and pushing the second touch pad to abut against the bottom plate; wherein when the outer cover is pressed and descends relative to the fixed base, it will drive the outer cover to abut against the conductive shaft rod.

[0008] Based on the above, when the outer cover is pressed by the user and descends relative to the fixed base, the outer cover will compress the elastic element and abut against the conductive shaft rod, so that the outer cover is in an electrically conductive state with the conductive shaft rod, the second connecting member, the second touch pad and the bottom plate in sequence, and then the second touch pad presses and touches the virtual knob displayed on the bottom plate, so as to achieve the function of the knob switch having pressing and touching.

[0017] Regarding the detailed description and technical content of the present application, it will be described below in conjunction with the drawings. However, the attached drawings are only for illustrative purposes and are not intended to limit the present application.

[0018] Please refer to Figures 1 to 8 As shown, the present application provides a rotary switch with a pressing mechanism. This rotary switch 10 mainly includes a fixed base 1, a rotatable cover 2, a conductive shaft 3, an elastic element 4, and a touch component 5.

[0019] As Figures 1 to 5 、 Figures 7 to 8 As shown, the fixed base 1 has a bottom plate 11 and a circular tube wall 12 extending from the bottom plate 11. Moreover, the bottom plate 11 is a part of a touch panel (not shown in the figure). That is, the fixed base 1 of this embodiment is integrally extended and formed from the touch panel, but it is not limited thereto. The circular tube wall 12 and the bottom plate 11 can also be separate elements. The bottom plate 11 is the touch panel, and the circular tube wall 12 is adhered to the bottom plate 11 to form the fixed base 1.

[0020] As Figures 1 to 8 As shown, the rotatable cover 2 is made of a conductive material. The rotatable cover 2 includes an outer cover 20 that is rotatably and liftably connected above the fixed base 1, and an inner cover 21 that is sandwiched between the fixed base 1 and the outer cover 20 and rotates with the outer cover 20. The inner cover 21 is provided with a through hole 211 configured corresponding to the outer cover 20 and a first setting portion 22 configured corresponding to the bottom plate 11.

[0021] In addition, the outer cover 20 has an inner top wall 201. The inner top wall 201 has a downward protrusion 202 and a receiving hole 203 recessed from the bottom of the downward protrusion 202. A positioning ring groove 212 is recessed at the top of the inner cover 21 and formed on the inner periphery of the through hole 211. And as Figure 4 、 Figure 7 As shown, the cross-section of the positioning ring groove 212 is a T-shaped groove, but it is not limited thereto. The cross-section of the positioning ring groove 212 can also be any geometric shape such as a rectangle, a triangle, etc.

[0022] Among them, a plurality of concave grooves 204 are provided on the inner periphery of the outer cover 20, and a plurality of convex blocks 213 are extended on the outer periphery of the inner cover 21 and are liftably embedded in the plurality of concave grooves 204, so that the inner cover 21 can rotate with the outer cover 20. However, the outer cover 20 can also be lifted relative to the inner cover 21. A guiding slope 205 with a gradually increasing thickness in a direction away from the bottom plate 11 is provided at the bottom edge of the inner periphery of the outer cover 20.

[0023] As Figures 1 to 2 、 Figure 4 、 Figure 7As shown, the knob switch 10 of the present application further includes a connection mechanism 6. The connection mechanism 6 includes an annular groove 61 formed in one of the fixed base 1 and the outer cover 20, and one or more locking blocks 62 extending from the other of the fixed base 1 and the rotatable cover 2. The locking blocks 62 can be slidably engaged with the annular groove 61 along the circumferential and axial directions of the annular groove 61, so that the outer cover 20 can rotate and lift relative to the fixed base 1.

[0024] Furthermore, one of the fixed base 1 and the inner cover 21 extends an annular gear 7 arranged parallel to the annular groove 61, and the other of the fixed base 1 and the inner cover 21 extends one or more convex teeth 8. The convex teeth 8 are engaged with the annular gear 7, so that when the user rotates the rotatable cover 2 with a finger, a scale feel is generated when the convex teeth 8 slide across the annular gear 7.

[0025] Specifically described as follows, the number of the locking blocks 62 in this embodiment is one. The annular groove 61 is formed on the inner peripheral edge of the outer cover 20. The locking block 62 is an inclined annular ring 621 extending from the outer peripheral edge of the circular tube wall 12 and gradually reducing in thickness in a direction away from the bottom plate 11 and capable of abutting against the guiding slope 205. The inner cover 21 abuts above the inclined annular ring 621. The annular gear 7 is formed on the inner peripheral edge of the circular tube wall 12. The convex teeth 8 extend from the bottom of the inner cover 21, but this is not limiting. The annular groove 61 can also be formed on the outer peripheral edge of the circular tube wall 12, the locking block 62 can also extend from the inner peripheral edge of the outer cover 20, the annular gear 7 can also extend from the bottom of the inner cover 21, and the convex teeth 8 can also extend from the inner peripheral edge of the circular tube wall 12.

[0026] As Figures 1 to 2 、 Figures 4 to 8 shown, the conductive shaft rod 3 is made of a conductive material. The conductive shaft rod 3 is movably inserted through the through hole 211 and received and limited in the receiving hole 203. The conductive shaft rod 3 has a second setting portion 31 arranged corresponding to the bottom plate 11, and a first tenon 32 protruding from the outer peripheral edge of the conductive shaft rod 3 is arranged between the inner top wall 201 and the positioning ring groove 212.

[0027] As Figures 1 to 2 、 Figure 4 、 Figures 6 to 7 shown, the elastic element 4 is elastically supported between the outer cover 20 and the conductive shaft rod 3 and pushes against the conductive shaft rod 3 to form a spacing S between the outer cover 20 and the conductive shaft rod 3. The elastic element 4 is an elastic rubber cap 41. The elastic rubber cap 41 has a cap portion 42 and a bowl-shaped foot 43. The cap portion 42 is engaged with the positioning ring groove 212. Therefore, the cross-section of the cap portion 42 is a T-shaped block that is shape-fitted to the T-shaped groove, but this is not limiting. The cross-section of the cap portion 42 can be any geometric shape that is shape-fitted to the positioning ring groove 212.

[0028] The bowl-shaped foot 43 extends from the top of the cap portion 42 to abut against the inner top wall 201 and is sleeved and positioned outside the lower protrusion 202. The cap portion 42 is provided with a through hole 421. The conductive shaft rod 3 passes through the through hole 421. When the first tenon 32 is engaged with the cap portion 42 and the outer cover 20 abuts against the conductive shaft rod 3 to apply a downward thrust to the conductive shaft rod 3, the conductive shaft rod 3 will be locked and positioned by the first tenon 32, thereby preventing the conductive shaft rod 3 from moving downward and disengaging from the through hole 421.

[0029] As Figures 1 to 2 , Figures 4 to 5 , Figures 7 to 8 shown, the touch component 5 includes a first touch pad 51, a second touch pad 52, a first connecting member 54 and a second connecting member 55 made of a conductive material. The first connecting member 54 is connected between the first setting portion 22 and the first touch pad 51 and pushes the first touch pad 51 to abut against the bottom plate 11, so that the bottom plate 11 and the first touch pad 51 are in an electrically conductive state. The second connecting member 55 is connected between the second setting portion 31 and the second touch pad 52 and pushes the second touch pad 52 to abut against the bottom plate 11, so that the bottom plate 11 and the second touch pad 52 are in an electrically conductive state.

[0030] Further explanation is as follows. The inner cover 21 extends a protruding rod 214. The first setting portion 22 and the second setting portion 31 are respectively a concave hole 9 opened from the bottom of the protruding rod 214 and the bottom of the conductive shaft rod 3. The first touch pad 51 and the second touch pad 52 respectively protrude a central axis 53. The first connecting member 54 and the second connecting member 55 are respectively a helical spring 56 with one end inserted into each concave hole 9 and the other end sleeved on each central axis 53. Each central axis 53 extends a second tenon 531 for engaging each helical spring 56.

[0031] As Figures 4 to 6 shown, in one use state of the rotary switch 10 of the present application, the first connecting member 54 is connected between the first setting portion 22 and the first touch pad 51 and pushes the first touch pad 51 to abut against the bottom plate 11, so that the bottom plate 11 and the first touch pad 51 are in an electrically conductive state. When the user rotates the rotatable cover 2, the first touch pad 51 will be driven to rotate accordingly, and then the first touch pad 51 will perform a rotary touch on the virtual knob displayed on the bottom plate 11 (touch panel), so as to achieve the function that the rotary switch 10 has rotary touch.

[0032] In addition, at this time, the rotatable cover 2 is not pressed by the user. Therefore, the elastic element 4 elastically supports between the outer cover 20 and the conductive shaft rod 3 and pushes to form a distance S between the conductive shaft rod 3 and the outer cover 20, so that the outer cover 20 and the conductive shaft rod 3 are in a resistive break state, that is, the outer cover 20 and the second touch pad 52, the bottom plate 11 are in a resistive break state.

[0033] As Figures 7 to 8As shown, in another usage state of the rotary switch 10 of the present application, when the outer cover 20 is pressed by the user and descends relative to the fixed base 1, the outer cover 20 will compress the elastic element 4 and abut against the conductive shaft rod 3, so that the outer cover 20 is electrically connected to the conductive shaft rod 3, the second connecting member 55, the second touch pad 52 and the bottom plate 11 in sequence, thereby enabling the second touch pad 52 to perform a pressing touch on the virtual knob displayed on the bottom plate 11 (touch panel), so as to achieve the function that the rotary switch 10 has a pressing touch function.

[0034] Furthermore, the rotary switch 10 of the present application uses the elastic element 4 to push against the conductive shaft rod 3 to form a distance S between the outer cover 20. The clamping block 62 can be slidably engaged with the annular groove 61 along the circumferential and axial directions of the annular groove 61, so as to achieve the actions that the outer cover 20 can rotate and lift relative to the fixed base 1 with a simple structure, and the outer cover 20 can abut against the conductive shaft rod 3 when pressed, and the conductive shaft rod 3 will be clamped and positioned by the first tenon 32 to avoid deviation, so that the rotary switch 10 has the advantages of simple assembly structure, stability and cost savings.

[0035] In summary, the rotary switch with a pressing mechanism of the present application can indeed achieve the expected usage purpose, solve the conventional deficiencies, and has industrial applicability, novelty and progressiveness, fully meeting the requirements for patent application. It is filed according to the Patent Law to protect the rights of the creator.
