Description

Technical Field

[0001] This invention relates to a device, and more particularly to a knob device. Background Technology

[0002] Existing rotary knobs trigger the touchscreen display panel by conducting electrical charges from the human body. However, these knobs often trigger the touchscreen display panel before the human body even touches it, resulting in unexpected signals entering the panel. In other words, existing rotary knobs are susceptible to electromagnetic interference or static electricity, leading to "ghost touch" or "false touch" phenomena.

[0003] Therefore, the inventor believed that the above-mentioned defects could be improved, and thus devoted himself to research and applied scientific principles, and finally proposed an invention that is reasonably designed and effectively improves the above-mentioned defects.

[0009] Optionally, the external conductive component includes: a first exposed pad disposed on the side of the base away from the operating cover; a conductive ring disposed on the base; and a first conductive bridge disposed between the conductive ring and the first exposed pad, wherein the first conductive bridge electrically couples the conductive ring and the first exposed pad; wherein, when the operating cover is in the triggered position, multiple reset conductive elements can contact the conductive ring to trigger the touch function display panel through the conductive ring and the first exposed pad.

[0010] Optionally, the first conductive bridge is defined as a conductive compression spring.

[0011] Optionally, the external conductive component includes: a plurality of second exposed pads disposed on the side of the base away from the operating cover and spaced apart from each other; a plurality of second conductive bridges disposed between the plurality of second exposed pads and a plurality of contacts, each second conductive bridge electrically coupling at least one contact to at least one second exposed pad; wherein, when the operating cover rotates relative to the base, at least one of the plurality of contacts is electrically coupled to one of the second exposed pads through one of the second conductive bridges.

[0012] Optionally, each second conductive bridge includes: a fixing plate fixed to the base; a first contact claw extending from the fixing plate toward the annular circuit board, the end of the first contact claw being able to elastically abut against one of the plurality of contacts to electrically couple the one contact; and a second contact claw extending from the fixing plate toward the base, the end of the second contact claw being able to elastically abut against one of the plurality of second exposed pads.

The following embodiments will further describe the relevant technical content of this invention in detail, but the disclosed content is not intended to limit the scope of protection of this invention.

[0028] It should be understood that while terms such as "first," "second," and "third" may be used in this document to describe various components or signals, these components or signals should not be limited by these terms. These terms are primarily used to distinguish one component from another, or one signal from another. Furthermore, the term "or" as used herein may, depending on the context, include any combination of one or more of the associated listed items.

[0029] Additionally, in the following description, if it is indicated that a specific diagram is referred to or as shown in a specific diagram, it is only for emphasis in the following description that most of the relevant content appears in that specific diagram, but it does not limit the following description to refer only to that specific diagram.

[0030] See Figures 1 to 10As shown, this embodiment provides a knob device 100, which can be mounted on a touch-screen display panel (not shown). In practice, the operation signal sent by the knob device 100 is identified and responded to by an application in the touch-screen display panel, and the identification and response between the knob device 100 and the touch-screen display panel is not only prior art but also not the focus of this invention, and will not be specifically described here.

[0031] Cooperate Figures 1 to 3 As shown, the knob device 100 includes a base 1, an operating cover 2 rotatably disposed on the base 1, an annular circuit board 3 disposed within the base 1, a brake ring 4 fixed to the annular circuit board 3 and connected to the operating cover 2, a resistance member 5 fixed to the base 1 and abutting against the brake ring 4, a plurality of elastic members 6 disposed on at least one of the brake ring 4 and the annular circuit board 3, a plurality of conductive trigger members 7 fixed to the side of the operating cover 2 facing the base 1, and a plurality of reset conductive members 8 disposed on the brake ring 4. Next, the components of the knob device 100 and their connection relationships will be described.

[0032] See again Figures 1 to 4 As shown, the base 1 in this embodiment is made of insulating material and consists of an upper component 11 and a lower component 12, but the present invention is not limited thereto. Furthermore, for ease of subsequent explanation, the base 1 is defined with a thickness direction D1.

[0033] The base 1 has a viewing hole H2 along the thickness direction D1, which allows the icons of the touch function display panel to be displayed (i.e., the operator can see the icons of the touch function display panel through the viewing hole). Preferably, the viewing hole H2 is located in a central region of the base 1, but this is not a limitation of the invention. For example, in other embodiments not shown, the viewing hole H2 may be omitted.

[0034] Furthermore, the base 1 also includes an external conductive component 13, which is the final circuit path used to trigger the touch-sensitive display panel. This is in conjunction with... Figures 4 to 6 As shown, for the pressing operation of the operating cover 2, the external conductive component 13 may include a first exposed pad 131, a conductive ring 132, and a first conductive bridge 133 disposed on the lower component 12. The first exposed pad 131 is disposed on the side of the lower component 12 away from the operating cover 2, while the conductive ring 132 is disposed on the base 1.

[0035] Furthermore, the first conductive bridging member 133 is disposed between the conductive ring 132 and the first exposed pad 131, and the first conductive bridging member 133 is electrically coupled to the conductive ring 132 and the first exposed pad 131. Accordingly, when the operating cover 2 is pressed (i.e., as...), Figure 10 As shown, when the operation cover 2 is in the trigger position P1, multiple reset conductive elements 8 can contact the conductive ring 132 to trigger the touch function display panel (described in detail later) through the conductive ring 132 and the first exposed pad 131.

[0036] Preferably, the first conductive bridging member 133 may be a conductive compression spring to ensure the electrical reliability between the conductive ring 132 and the first exposed pad 131.

[0037] Furthermore, cooperation Figure 4 , Figure 5 and Figure 7 As shown, for the rotation operation of the operating cover 2, the external conductive component 13 may include a plurality of second exposed pads 134 and a plurality of second conductive bridges 135 disposed on the lower member 12. The plurality of second exposed pads 134 are disposed on the side of the lower member 12 away from the operating cover 2 and are spaced apart from each other. The plurality of second conductive bridges 135 are disposed between the plurality of second exposed pads 134 and a plurality of contacts CP of the annular circuit board 3, and each second conductive bridge 135 can electrically couple at least one contact CP to at least one second exposed pad 134. Accordingly, when the operating cover 2 rotates relative to the base 1, at least one of the contacts CP is electrically coupled to one of the second exposed pads 134 through one of the second conductive bridges 135.

[0038] To ensure that each of the second conductive bridge members 135 can stably and non-fixedly electrically couple at least one of the contacts CP to one of the second exposed pads 134, each of the second conductive bridge members 135 may include a fixing plate 1351, a first contact claw 1352 and a second contact claw 1353 connected to the fixing plate 1351. The fixing plate 1351 is fixed to the lower member 12 so that the second conductive bridge member 135 does not rotate with the operating cover 2. Furthermore, the first contact claw 1352 extends from the fixing plate 1351 toward the annular circuit board 3, and the end of the first contact claw 1352 can elastically abut against one of the contacts CP to electrically couple that contact CP. The second contact claw 1353 extends from the fixing plate 1351 toward the base 1, and the end of the second contact claw 1353 can elastically abut against one of the second exposed pads 134. In other words, the first contact claw 1352 and the second contact claw 1353 can form a gradually widening opening.

[0039] Cooperate Figure 3 , Figure 9 and Figure 10 As shown, in order to perform pressing and rotating operations, the operating cover 2 can rotate relative to the base 1, and the operating cover 2 can also move along the thickness direction D1 between the trigger position P1 and the release position P2.

[0040] Specifically, the operating cover 2 includes a support base 21, a conductive outer cover 22 disposed on the support base 21, and an anti-slip sleeve 23. The support base 21 is rotatably disposed on the upper member 11 (i.e., a portion of the upper member 11 is located within the support base 21), and the support base 21 can be assembled to the brake ring 4, allowing the support base 21 to drive the brake ring 4 to rotate relative to the base 1. Multiple conductive feet (not shown) of the conductive outer cover 22 pass through the side of the support base 21 facing the base, positioning the multiple conductive feet between the brake ring 4 and the support base 21 to electrically couple multiple conductive triggers 7.

[0041] See again Figure 3 , Figure 4 and Figure 9As shown, the brake ring 4 can be used to cooperate with the resistance member 5, allowing the operating cover 2 to be assembled onto the base 1. Specifically, the brake ring 4 includes a body 41, a plurality of through holes H42, and a plurality of annular posts 43. The body 41 is annular, and each of the through holes H42 penetrates the body 41 along the thickness direction D1. The plurality of through holes H42 are arranged annularly on the body 41 and their positions correspond to the conductive ring of the external conductive component. Furthermore, the plurality of annular posts 43 are respectively fitted onto the plurality of through holes H42 for the installation of the plurality of reset conductive members 8; that is, the plurality of annular posts 43 are also arranged annularly.

[0042] It should be noted that when the knob device 100 is rotated, the brake ring 4 can cooperate with the resistance member 5 to provide appropriate resistance. Specifically, the resistance member 5 is fixed to the upper member 11 and located within the support base 21, and the position of the resistance member 5 corresponds to the brake ring 4. The body 41 of the brake ring 4 has a plurality of teeth T arranged in a ring on the side away from the lower member 12, and the plurality of teeth T face the resistance member 5, so that a protrusion K of the resistance member 5 can abut against any of the teeth T of the brake ring 4 to temporarily restrict rotation. Accordingly, when the operating cover 2 is subjected to a rotational force exceeding a threshold, the protrusion K can cross the teeth T to provide a positioning feel during rotation.

[0043] Cooperate Figure 3 , Figure 4 and Figure 9 As shown, in this embodiment, the annular circuit board 3 is fixed to the side of the brake ring 4 facing the base, and the annular circuit board 3 can be rotated relative to the base 1 by the brake ring 4. The annular circuit board 3 has multiple contacts CP arranged in a ring for signal determination during rotation of the knob device 100. Additionally, the annular circuit board 3 also has multiple clearance holes H3 for multiple reset conductive elements 8 to pass through, allowing charge to be conducted to the touch function display panel through the multiple conductive triggers 7 and the multiple reset conductive elements 8 when the operating cover 2 is pressed.

[0044] See again Figure 3 , Figure 4 and Figure 9As shown, the plurality of elastic members 6 are used to elastically abut against the plurality of conductive trigger members 7, thereby allowing the operating cover 2 to move from the trigger position P1 to the release position P2. In this embodiment, the plurality of elastic members 6 are disposed within the plurality of mounting slots 44 of the brake ring 4, that is, the plurality of elastic members 6 are located on the annular circuit board 3. Specifically, the brake ring 4 also includes the plurality of mounting slots 44 disposed on the body 41, the plurality of mounting slots 44 communicating with the surface of the annular circuit board 3 in the thickness direction D1 and respectively adjacent to the plurality of annular posts 43. Accordingly, when the plurality of conductive trigger members 7 are mounted on the plurality of elastic members 6, they can be close to the plurality of reset conductive members 8.

[0045] Cooperate Figure 3 , Figure 4 and Figure 9 As shown, a plurality of conductive triggers 7 are fixed on the operation cover 2 and electrically coupled to the conductive outer cover 22 of the operation cover 2, and the positions of the plurality of conductive triggers 7 also correspond to the plurality of elastic members 6 respectively.

[0046] In this embodiment, each of the conductive triggers 7 includes a fixing plate 71 and a reset plate 72 and a trigger plate 73 connecting the fixing plate 71. The fixing plate 71 is arranged generally perpendicular to the thickness direction D1 to be assembled on the side of the operating cover 2 facing the base 1, and the fixing plate 71 can be connected to the conductive foot to receive charge.

[0047] Furthermore, the cross-section of the reset plate 72 is generally L-shaped in this embodiment, and the reset plate 72 extends from the fixed plate 71 along the thickness direction D1, such that a portion of the reset plate 72 (i.e., the end perpendicular to the thickness direction D1) corresponds to one of the elastic elements 6. Moreover, the trigger plate 73 is generally parallel to the fixed plate 71, and the trigger plate 73 extends from the fixed plate 71 and is located on one side of the reset plate 72. A portion of the trigger plate 73 corresponds to one of the reset conductive elements 8.

[0048] Accordingly, when the operating cover 2 is in the triggered position P1, each of the reset plates 72 presses against the corresponding elastic element 6 to generate the elastic force, and the plurality of trigger plates 73 push against the plurality of reset conductive elements 8 to conduct charge to the external conductive component 13. Conversely, when the operating cover 2 is in the released position P2, the plurality of elastic elements 6 release the elastic force to push against the plurality of reset plates 72, causing the plurality of trigger plates 73 to move away from the plurality of reset conductive elements 8 and thus be unable to conduct charge.

[0049] See again Figure 3 , Figure 4and Figure 9 As shown, the positions of the plurality of reset conductive elements 8 correspond to the plurality of conductive trigger elements 7 respectively, and the plurality of reset conductive elements 8 can pass through the plurality of clearance holes H3 to selectively abut against and conduct charge to the external conductive component 13.

[0050] In other words, when the operating cover 2 is in the released position P2, each of the reset conductive elements 8 is spaced apart from at least one of the corresponding conductive trigger element 7 and the external conductive component 13, preventing the charge on the operating cover 2 from being conducted to the external conductive component via the multiple reset conductive elements 8. Conversely, when the operating cover 2 is in the triggered position P1, the multiple reset conductive elements 8 receive the charge via the conductive trigger element and further conduct it to the external conductive component 13.

[0051] Preferably, each of the reset conductive elements 8 is spaced apart from the corresponding conductive trigger element 7 and the external conductive assembly 13. Furthermore, the shortest interval S1 along the thickness direction D1 between each reset conductive element and the corresponding conductive trigger element 7 (the trigger plate 73) can be greater than or equal to 0.3 mm, thereby reducing the risk of incorrect judgment when the operating cover 2 is rotated. Moreover, the shortest interval S2 along the thickness direction D1 between each reset conductive element 8 and the external conductive assembly 13 (the conductive ring 132) can also be designed to be greater than or equal to 0.1 mm, thereby reducing coupling through air isolation.

[0052] In practice, each of the reset conductive elements 8 is defined as a double-ended spring pin. Each double-ended spring pin can be fixed to the annular post 43 and pass through the through hole H42. The first end 81 of each double-ended spring pin can be pushed by the conductive trigger element, causing the second end 82 of each double-ended spring pin to pass through the clearance hole H3 to electrically couple to the external conductive component 13. However, this invention is not limited to this.

[0053] For example, in other embodiments of the present invention not shown, each of the reset conductive elements 8 may also be a conductive spring connected to the conductive trigger element 7, and each of the conductive springs has a first portion corresponding to the elastic element 6 and a second portion corresponding to the conductive ring 132. Accordingly, when the operating cover 2 is in the trigger position P1, each of the conductive trigger elements 7 drives the first portion to press the elastic element 6 corresponding to the position to generate an elastic force, and each of the second portions contacts the conductive ring for electrical coupling.

[0054] [Technical Effects of the Embodiments of the Invention]
