Detailed ways

The detailed description and technical content of the utility model are now described as follows with reference to the accompanying drawings:

Please refer to Figures 1 to 6. The utility model provides a knob device 10, which is used on a touch screen 30 to touch the touch screen 30. The touch function of the knob device 10 of the utility model includes rotation touch and click touch. The rotation touch referred to herein means that after the knob device 10 is operated, the menu content displayed on the touch screen 30 is selected, which is similar to operating a mouse to slide a cursor, and the click touch is to select the menu content displayed on the touch screen 30, which is similar to clicking a mouse button.

The knob device 10 includes a base 11 and an operating cap 12. The base 11 serves as a basic carrier of the knob device 10 to provide the operating cap 12 for installation. The base 11 is provided with a plurality of elastic return members 111. The plurality of elastic return members 111 have elastic characteristics. The plurality of elastic return members 111 can store elastic force after being compressed, and release the stored elastic force when the compression is released. The arrangement referred to in this article does not limit the plurality of elastic return members 111 to be evenly distributed on the base 11, but the plurality of elastic return members 111 are not concentrated in the same place of the base 11 and are sufficient to support the operating cap 12.

The operating cap 12 is provided as an operator in the knob device 10 and is pressed against by the multiple elastic return members 111. The operating cap 12 has a rotation stroke 121 and a pressing stroke 122 based on the user's operation. When the operating cap 12 performs the rotation stroke 121, the operating cap 12 rotates relative to the base 11. When the operating cap 12 performs the pressing stroke 122, the operating cap 12 presses the multiple elastic return members 111 and moves relative to the base 11.

The operating cap 12 is provided with a plurality of touch pads 123, each of which has a working surface 124, and the working surface 124 is located on one side of one of the plurality of touch pads 123. For example, when the knob device 10 is implemented with the touch screen 30, the working surfaces 124 of the plurality of touch pads 123 face the touch screen 30 and can make contact with the touch screen 30. It should be understood that when the working surfaces 124 of the plurality of touch pads 123 make contact with the touch screen 30, the electrical signal of the touch screen 30 will be changed, so that the touch screen 30 generates corresponding control, such as a selection operation or a click operation. In addition, the working surfaces 124 of the plurality of touch pads 123 are not at the same height, and the working surface 124 of at least one of the plurality of touch pads 123 is not on the same horizontal plane as the working surfaces 124 of the rest of the plurality of touch pads 123. When the operating cap 12 performs the rotation stroke 121, only the plurality of working surfaces 124 of the plurality of touch pads 123 contact the touch screen 30 to realize the rotation touch of the knob device 10, and when the operating cap 12 performs the rotation stroke 121, the plurality of working surfaces 124 of the plurality of touch pads 123 all contact the touch screen 30 to realize the click touch of the knob device 10. It should be noted that the present invention does not limit the direction of the rotation stroke 121, and the operating cap 12 can rotate relative to the base 11 based on the operation situation, and make the knob device 10 generate corresponding rotation touch.

For the implementation of the knob device 10, please refer to Figures 1 to 6. Assume that the knob device 10 is not operated initially and does not perform the rotation stroke 121 and the pressing stroke 122. At this time, the working surface 124 of at least one of the multiple touch pads 123 is not in contact with the touch screen 30, while the multiple working surfaces 124 of the rest of the multiple touch pads 123 are in contact with the touch screen 30, as shown in Figures 1 to 3 and 5. Please refer to Figure 3. When the knob device 10 is operated to make the operating cap 12 perform the rotation stroke 121, the operating cap 12 does not compress the multiple elastic return members 111, but only drives the multiple touch pads 123 to rotate, so that the multiple working surfaces 124 change the position on the touch screen 30. At this moment, the operating cap 12 contacts the touch screen 30 with the multiple working surfaces 124 of the multiple touch pads 123. The touch screen 30 recognizes the rotation touch of the knob device 20 based on the electrical signal generated between the operating cap 12 and the knob device 20, and executes the selection function.

6 , when the knob device 10 is subjected to force and the operating cap 12 performs the pressing stroke 122, the operating cap 12 compresses the multiple elastic return members 111, so that the multiple working surfaces 124 of the multiple touch pads 12 all contact the touch screen 30. That is to say, the multiple working surfaces 124 that are in contact with the touch screen 30 when the operating cap 12 is not performing the pressing stroke 122 remain in contact with the touch screen 30, and the multiple working surfaces 124 that are not in contact with the touch screen 30 when the operating cap 12 is not performing the pressing stroke 122 come into contact with the touch screen 30. In this way, the touch screen 30 can recognize that the knob device 10 is a click touch based on the electrical signal generated between the knob device 10 and the operating cap 12, and execute the click function. When the knob device 10 stops being subjected to force and the operating cap 12 is pushed back by the elastic restoring members 111 , the operating cap 12 drives the touch pads 123 to return, so that the working surface 124 of at least one of the touch pads 123 is restored to not contact the touch screen 30 .

As can be seen from the above, the knob device 10 of the present invention determines the operation of the knob device 10 through the height relationship between the multiple working surfaces 124 of the multiple touch pads 123. Further, in conjunction with the implementation of the touch screen 30, when the operating cap 12 performs the rotation stroke 121, the multiple working surfaces 124 of some of the multiple touch pads 123 contact the touch screen 30 to achieve the rotation touch of the knob device 10. When the operating cap 12 performs the pressing stroke 122, the multiple working surfaces 124 of the multiple touch pads 123 contact the touch screen 30 together to achieve the click touch of the knob device 10. Compared with the conventional method, the knob device 10 of the present invention does not need to be independently designed for the touch function of the multiple touch pads 123, which can effectively reduce the problem of cumbersome settings and facilitate the implementation of the knob device 10.

Continuing from the above, please refer to FIG. 1, FIG. 2 and FIG. 5. In one embodiment, the operating cap 12 is provided with a bracket 125, and the bracket 125 connects the base 11 and the plurality of touch pads 123. The bracket 125 forms a plurality of assembly holes 126, and each of the plurality of assembly holes 126 is provided for assembly with one of the plurality of touch pads 123. Please refer to FIG. 7. In this embodiment, the number of the plurality of assembly holes 126 is greater than the number of the plurality of touch pads 123. Each of the plurality of touch pads 123 can be assembled with one of the plurality of assembly holes 126 based on demand, wherein the plurality of touch pads 123 can be used as the identification of the knob device 10 based on the polygonal pattern formed by the touch controller when the operating cap 12 does not perform the pressing stroke 122. To explain in more plain words, taking the number of the touch pads 123 that realize touch control when the operating cap 12 has not performed the pressing stroke 122 as three, assuming that a plurality of the knob devices 10 are provided on the same touch screen 30, each of the plurality of the knob devices 10 can be identified by the computing component associated with the touch screen 30 based on the different triangles configured by the plurality of touch pads 123 provided thereon, thereby allowing the same touch screen 30 to have a plurality of the knob devices 10 and perform different touch controls on the touch screen 30 respectively.

Continuing from the above, please refer to FIG. 5 and FIG. 6. Since the multiple working surfaces 124 of the multiple touch surfaces change from unequal heights to equal heights after the operating cap 12 performs the pressing stroke 122, at least one of the multiple touch pads 123 needs to be extended and retracted relative to the other multiple touch pads 123. In one embodiment, at least one of the multiple touch pads 123 is provided with at least one auxiliary restoration member 127. The at least one auxiliary restoration member 127 is connected to the operating cap 12 and is located on a side of at least one of the multiple touch pads 123 away from the multiple working surfaces 124 to assist the restoration of at least one of the multiple touch pads 123 after extension and retraction. In this embodiment, the at least one auxiliary restoration member 127 is provided in the multiple touch pads 123 to realize the touch when the operating cap 12 does not perform the pressing stroke 122.

On the other hand, please refer to Figures 1 and 2 again. The knob device 10 of the present invention can provide tactile feedback after being rotated. In one embodiment, the operating cap 12 is provided with a tactile feedback member 128, and the tactile feedback member 128 faces the base 11 and can rotate relative to the base 11 as the operating cap 12 rotates. A plurality of mountain portions 129 and a plurality of valley portions 130 are formed on the tactile feedback member 128, and the plurality of mountain portions 129 and the plurality of valley portions 130 face the base 11 and are arranged in succession. The base 11 is provided with at least one column 112, and the at least one column 112 is connected to at least one of the plurality of elastic return members 111 and is pushed by at least one of the plurality of elastic return members 111, so as to contact the surface of the tactile feedback member 128. When the tactile feedback member 128 rotates, the at least one column 112 changes the position of contacting the plurality of hills 129 and the plurality of valleys 130 , thereby enabling the operating knob to provide tactile feedback to enhance the operating feel.

Furthermore, the tactile feedback element 128 has a plurality of notches 131 . The notches 131 are disposed facing the touch pads 123 to facilitate the extension and retraction of at least one of the touch pads 123 .

On the other hand, referring to FIG. 5 to FIG. 8 again, in order to facilitate the knob device 10 to be disposed on the touch screen 30, in one embodiment, the knob device 10 has an adhesive 13 disposed on the base 11. Further, the operating cap 12 has an inner ring edge 132 and an outer ring edge 133. The knob device 10 can be disposed close to the inner ring edge 132 of the operating cap 12 or close to the outer ring edge 133 of the operating cap 12 based on the needs. When the base 11 is disposed close to the outer ring edge 133 of the operating cap 12, the knob device 10 can provide a better dustproof effect.

Continuing from the above, please refer to FIG. 1 and FIG. 2 , the base 11 includes a base plate 113 connected to the plurality of elastic restoring members 111, and a ring 114 disposed on the base plate 113. The base 11 and the ring 114 are provided with at least one assembly groove 115 and at least one assembly block 116. The at least one assembly groove 115 is matched and assembled with the at least one assembly block 116. Furthermore, the ring 114 is connected to the bracket 125. The bracket 125 can be arranged along the inner ring periphery or the outer ring periphery of the ring 114. The ring 114 is provided with a retaining wall 117 to limit the assembly position of the bracket 125. The retaining wall 117 is located at the outer edge or the inner edge of the ring 114 according to the position of the bracket 125. The retaining wall 117 is raised to limit the position of the bracket 125.
