Description

Touch knob device

The present invention relates to a knob device, and more particularly to a touch knob device.

In order to provide a more user-friendly interface for portable information products, the integration of touch panels or touch pads has become a trend. Relevant panel manufacturers and IC design companies have listed touch panel technology as their main R&D projects, and related technologies and products have also been applied to everyday electronic products, such as mobile phones, computers and personal mobile assistants And other information products.

At present, the most commonly used touch devices are mainly divided into resistive and capacitive. The main working principle of capacitive touch devices is to sense an electrical characteristic called capacitance. When two electrically conductive objects are close to each other without touching, their electric fields will interact to form a capacitance. The upper and lower surfaces of the touch panel structure are respectively conductive layers formed by electrode lines in staggered directions. The finger is also an electrical conductor. When the finger is placed on the touch panel, a very small capacitance is formed between the electrode circuit of the touch panel and the finger. The microprocessor detects the position touched by the user by changing the capacitance value. However, in the era of the prevalence of touch control, mechanical buttons are still indispensable in the cockpit, which allows the driver not to look away from the road to increase safety. However, in order to place the knobs, as shown in FIG. 1, in a fixed area, the knob 10 occupies a part of the area, and the remaining area belongs to the touch display panel 12.

Please refer to Fig. 2, Fig. 3, Fig. 4 and Fig. 5 to introduce the touch knob device of the present invention, which includes a knob body 14, a fixing base 16, a base 18, and two first The touch pad 20, a second touch pad 22, a connecting rod 24 and a fixing plate 26, wherein the knob body 14, the first touch pad 20, the second touch pad 22, the connecting rod 24 and The fixing plate 26 is made of conductive material. For example, the material of the knob body 14 can be aluminum, and the first touch pad 20, the second touch pad 22, the connecting rod 24 and the fixing plate 26 can be copper foil or silver paste, and The first touch pad 20 or the second touch pad 22 may be round or square, and the diameter of the round is 3 to 5 mm. In this embodiment, the first touch pad 20 and the second touch pad 22 are circular as an example. The bottom of the knob body 14 has a groove 28. The groove 28 has an open end 30 and a closed end 32 opposite to each other. The closed end 32 extends from the groove 28 to the open end 30 so as to be formed in the groove 28. A convex shaft 34 of conductive material. In one embodiment, the convex shaft 34 may be located at the center of the closed end 32. The top and bottom of the fixing base 16 respectively have a slot 36 and a mounting groove 38. The convex shaft 34 is rotatably inserted into the slot 36 and receives the fixing base 16 in the groove 28. The base 18 is disposed in the installation groove 38 and exposed from the open end 30. The first touch pad 20 is provided on the bottom surface of the knob body 14 through conductive glue, the base 18 is located between the two first touch pads 20, and the bottom of the base 18 and the bottom surface of the first touch pad 20 are attached On a touch display panel 40, in this embodiment, the bottom of the base 18 can be fixed on the touch display panel 40 through double-sided tape. The side wall of the convex shaft 34 is provided with a recess 42 in which one end of a spring 44 is fixed, and the other end of the spring 44 is fixed with a steel ball 46. The inner wall of the slot 36 is a wavy surface, and the steel ball 46 is clamped in the wave形面。 On the surface. This wavy surface can increase the feel of the knob body 14 when it is rotated, that is, the sense of segment by segment. The bottom of the base 18 has a bottom groove 48 in which the second touch pad 22 is fixed, and the bottom surface of the second touch pad 22 is attached to the touch display panel 40. The second touch pad 22 and the first touch pad 20 are located in a straight line. In the present invention, the first touch pad 20 and the second touch pad 22 are directly attached to the touch display panel 40, so as to retain the touch knob device itself and enlarge the screen of the touch display panel 40 at the same time. The fixing plate 26 is located in the mounting groove 38 and is located between the base 18 and the fixing base 16. The connecting rod 24 is a long rod. The connecting rod 24 penetrates the base 18 and is located on the fixing plate 26 and the second touch pad 22 Between them, to connect the fixing board 26 and the second touch pad 22. In this embodiment, the second touch pad 22, the connecting rod 24 and the fixing plate 26 are integrally formed.

The touch display panel 40 has a control circuit, which can calculate the length between the first touch pads 20 and the center position between the first touch pads 20, that is, the position of the second touch pad 22. When the user touches the knob body 14, the knob body 14 squeezes the first touch pad 20 downward, so that the touch display panel 40 can sense the two coordinates of the first touch pad 20 by the control circuit. As shown in Figure 6, when the knob body 14 is rotated, the control circuit can also be used to detect that these two coordinates will also rotate. It is further determined whether to rotate clockwise or counterclockwise, and even the rotation angle is detected. According to the rotation direction and rotation angle of the two coordinates of the first touch pad 20, the touch display panel 40 utilizes a control circuit to perform corresponding functions. In addition, as shown in Figure 7, when the user presses the knob body 14 with his fingers, the knob body 14 squeezes the first touch pad 20 downward, and the knob body 14 passes through the fixing seat 16, the fixing plate 26 and The connecting rod 24 squeezes the second touch pad 22 downward, so that the touch display panel 40 can sense the three coordinates of the first touch pad 20 and the second touch pad 22 by using the control circuit, and then This performs the corresponding pressing function.

In addition to fixing the bottom of the base 18 to the touch display panel 40 through double-sided tape, the base 18 can also be implemented with a movable suction cup, so that double-sided tape is not required. Please refer to Figures 7 and 8(a). In Figure 8(a), the touch knob device 50 of the present invention is attached to the touch display panel 40 using a suction cup, and the touch display panel 40 further displays The input pattern (icon) 52, and the position of the touch knob device 50 must be different from the position of the input pattern 52, where the input pattern 52 refers to the application (APP) button displayed on the touch display panel 40, like a smart type The application button on the desktop of the mobile phone is the same as the application image on the computer screen. For example, the image of the recycling bin is a blue trash can. When the touch knob device 50 moves upward by pressing, since the control circuit can detect the three coordinates of the first touch pad 20 and the second touch pad 22, the touch display panel 40 uses the control circuit Determine whether the edge of the touch knob device 50 touches the edge of the input pattern 52, if so, the touch display panel 40 uses the control circuit to calculate the original position of the touch knob device 50, and moves the input pattern 52 to other appropriate positions. As shown in FIG. 8(b), the entire screen is optimized; if not, the touch display panel 40 uses the control circuit to maintain the original position of the input pattern 52.

To sum up, the present invention directly attaches the touch pad to the touch display panel to retain itself and enlarge the screen of the display panel at the same time, achieving two goals with one stone.

The above is only a preferred embodiment of the present invention, and is not used to limit the scope of implementation of the present invention. Therefore, all the shapes, structures, features and spirits described in the scope of the patent application of the present invention are equally changed and modified. , Should be included in the scope of patent application of the present invention.
