The detailed description and technical content of the present invention are now described in conjunction with the drawings as follows: Please refer to Figures 1 to 6. The present invention provides a rotary knob device 10, which is used on a touch screen 30 to touch the touch screen 30. The touch function of the rotary knob device 10 of the present invention includes rotation touch and click touch. The rotation touch referred to herein means that the rotary knob device 10 is operated to select the menu content displayed on the touch screen 30, which is similar to operating a mouse to slide the 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 base 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 elastic return members 111 have elastic characteristics. The elastic return members 111 can store elastic forces after being compressed and release the stored elastic forces when being released from compression. The arrangement referred to herein does not limit the elastic return members 111 to be uniformly distributed on the base 11, but the elastic return members 111 are not concentrated at 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 supported by the 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 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 the touch pads 123 has a working surface 124, and the working surface 124 is located on one side of one of the touch pads 123. For the implementation of the knob device 10 in combination with the touch screen 30, the plurality of working surfaces 124 of the touch pads 123 face the touch screen 30 and can come into contact with the touch screen 30. It should be understood that when the plurality of working surfaces 124 of the touch pads 123 come into contact with the touch screen 30, the electrical signal of the touch screen 30 will be changed, so that the touch screen 30 will generate corresponding control, such as being subjected to a selection operation or a click operation. Furthermore, the plurality of working surfaces 124 of the touch pads 123 are not at the same height, and the working surface 124 of at least one of the touch pads 123 is not on the same horizontal plane as the plurality of working surfaces 124 of the rest of the touch pads 123. When the operating cap 12 performs the rotation stroke 121, only the plurality of working surfaces 124 of a part of the 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 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. The operating cap 12 can rotate relative to the base 11 based on the operation situation, and the knob device 10 can generate a 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 the rotation stroke 121 and the pressing stroke 122 are not performed. At this time, the working surface 124 of at least one of the touch pads 123 does not contact the touch screen 30, and the working surfaces 124 of the rest of the touch pads 123 contact the touch screen 30, as shown in Figures 1 to 3 and 5. Please refer to FIG. 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 press the elastic return members 111, but only drives the touch pads 123 to rotate, so that the plurality of 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 plurality of working surfaces 124 of the touch pads 123. The touch screen 30 recognizes the rotation touch of the knob device 10 based on the electrical signal generated between the operating cap 12 and the knob device 10, 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 presses the elastic return members 111, so that the plurality of working surfaces 124 of the touch pads 123 are in contact with the touch screen 30. In other words, the plurality of working surfaces 124 are in contact with the touch screen when the operating cap 12 does not perform the pressing stroke 122. The user who touches the touch screen 30 keeps touching the touch screen 30, and the users of the plurality of working surfaces 124 who do not touch the touch screen 30 when the operating cap 12 does not perform the pressing stroke 122 start to touch the touch screen 30. In this way, the touch screen 30 can recognize that the rotary knob device 10 is a click touch based on the electrical signal generated between the rotary knob device 10 and the rotary knob device 10, and perform the click function. When the knob device 10 stops being subjected to force, the operating cap 12 is pushed up by the elastic return members 111 and returns, and 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 foregoing, the operation of the rotary knob device 10 is determined by the height relationship between the plurality of working surfaces 124 of the 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 plurality of working surfaces 124 of some of the touch pads 123 contact the touch screen 30 to achieve the rotation touch of the rotary knob device 10. When the operating cap 12 performs the pressing stroke 122, the plurality of working surfaces 124 of the touch pads 123 contact the touch screen 30 together to achieve the click touch of the rotary knob device 10. Compared with the conventional method, the new rotary knob device 10 does not need to be independently designed for the touch functions of the touch pads 123, which can effectively reduce the problem of complicated settings and facilitate the implementation of the rotary 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 . The bracket 125 connects the base 11 and the touch pads 123 . The bracket 125 forms a plurality of assembly holes 126 . Each of the assembly holes 126 is provided for assembling one of the touch pads 123 . Please refer to FIG. 7 . In the present embodiment, the number of the assembly holes 126 is greater than the number of the touch pads 123 . Each of the touch pads 123 can be assembled with one of the assembly holes 126 based on the needs. When the operating cap 12 does not perform the pressing stroke 122 , the touch pads 123 can be used as the identification of the knob device 10 based on the polygonal shape formed by the common configuration. To explain in more plain words, assuming that the number of touch pads 123 that realize touch control when the operating cap 12 does not perform the pressing stroke 122 is three, assuming that the same touch screen 30 is provided with a plurality of the knob devices 10, Each of the plurality of the knob devices 10 can be identified by the computing component matched with the touch screen 30 based on the different triangles configured by the touch pads 123 provided on itself, 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. After the operating cap 12 performs the pressing stroke 122, the plurality of working surfaces 124 of the touch surfaces change from unequal heights to equal heights, and at least one of the touch pads 123 needs to be extended or contracted relative to the rest of the touch pads 123. In one embodiment, at least one of the touch pads 123 is provided with at least one auxiliary return component 127. The at least one auxiliary return component 127 is connected to the operating cap 12 and is located on a side of at least one of the touch pads 123 that is far from the plurality of working surfaces 124 to assist the return of at least one of the touch pads 123 after extension or contraction. In this embodiment, the at least one auxiliary return member 127 is disposed on the touch pads 123 to realize the touch when the operating cap 12 does not perform the pressing stroke 122.

On the other hand, referring to FIG. 1 and FIG. 2 again, the new rotary knob device 10 can provide tactile feedback after being rotated. In one embodiment, the operating cap 12 is provided with a tactile feedback member 128, the tactile feedback member 128 faces the base 11 and can rotate relative to the base 11 as the operating cap 12 rotates.

When the tactile feedback member 128 rotates, the at least one column 112 changes the position of contacting the mountain portions 129 and the valley portions 130, so that the operation knob provides tactile feedback to enhance the operation feel.

Furthermore, the tactile feedback member 128 has a plurality of notches 131, and 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, please refer to Figures 5 to 8 again. In order to facilitate the setting of the knob device 10 on the touch screen 30, in one embodiment, the knob device 10 has an adhesive 13 arranged on the base 11. Furthermore, the operating cap 12 has an inner ring edge 132 and an outer ring edge 133. The knob device 10 can be arranged 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 demand. In terms of the arrangement of the base 11 close to the outer ring edge 133 of the operating cap 12, the knob device 10 can provide a better dustproof effect.
