Description

Technical Field

[0001] The utility model relates to the technical field of knobs, and in particular to a touch panel knob. Background Art

[0002] The Chinese patent publication number is CN109192587A, and the application publication date is January 11, 2019. The utility model is titled "A touch knob," comprising: a base; a rotating shaft, one end of which is fixed to the base; a screw cap rotatably mounted on the rotating shaft, the screw cap defining a receiving slot with its opening facing the base; an end of the rotating shaft, which is remote from the base, extending into the receiving slot and connected to the screw cap; the screw cap is capable of rotating about the rotating shaft and moving away from and toward the base within a predetermined distance; and at least one conductive touch head, which is disposed on the screw cap and located within the receiving slot and moves with the movement of the screw cap. The design of the touch knob of this utility model eliminates the need for additional mounting holes or slots to be machined on the cover of the touch panel for mounting the touch knob. The present invention also provides a touch device using the aforementioned touch knob. During actual operation, the touch sensing structure is arranged at intervals on the circumference around the center of the rotating shaft, correspondingly divided into eight sensing areas. The eight positioning holes of the turntable each correspond to a sensing area. By pressing and rotating the rotary cap, the conductive touch head and the turntable rotate a certain angle. The positioning post aligns and extends into a positioning hole of the turntable. The conductive touch head contacts or abuts the cover plate, corresponding to a sensing area, thus realizing a specific touch function. The conductive touch head corresponds to a specific sensing area and can realize a specific touch function. The rotation of the conductive touch head corresponds to different sensing areas. The disadvantage of this operation method is that the divided areas are limited, resulting in a lack of precision in the rotation segment, which urgently needs to be improved. Utility Model Content

DETAILED DESCRIPTION

[0023] The present invention will be described in further detail below with reference to the embodiments and drawings, but the embodiments of the present invention are not limited thereto.

[0024] Reference Figure 1-4 Figure 1 shows a touch panel knob, comprising a cap 10, an axis fixing seat 11, a housing 12, an axis 13, a fixing pin 14, a rotating portion 15, two spring plates 16, a conductive block A20, a conductive block B17, a pot 18, a switch body 24, and a conductive glass back cover 21. The conductive blocks A20 and B17 are configured to have different conductivities. The axis fixing seat 11 is correspondingly and fixedly mounted in the cap 10.

[0025] The upper portion of the axis 13 coaxially passes through the axis fixing seat 11 and extends to the upper portion of the inner cavity of the cap sleeve 10. The fixing pin 14 passes through the lower portion of the axis 13 and is perpendicular to the axis 13. The conductive glass back cover 21 is fixedly mounted on the bottom of the outer shell 12 to form a mounting cavity. The outer shell 12 is coaxially arranged below the cap sleeve 10, and the conductive glass back cover 21 is fixedly connected to the outer shell 12 by glue. A gap is formed between the lower surface of the cap sleeve 10 and the outer shell 12.

[0026] Conductive block A20 and conductive block B17 are interlocked and connected. Two latches 36 are integrally formed on the side of conductive block B17 facing conductive block A20. A slot 37 for the latches 36 is formed on the side of conductive block A20 facing conductive block B17, with the latches 36 forming interference fit with the slots 37. A quick-positioning protrusion 27 is formed on the side of conductive block A20 facing conductive block B17, while a positioning slot 26 is formed on the side of conductive block B17 facing conductive block A20, into which the quick-positioning protrusion 27 is inserted. This structural arrangement enables precise and rapid assembly, improving production efficiency.

[0027] The lower surface of the conductive block B17 is provided with a clearance groove 28 along its curvature for accommodating the conductive metal sheet 19; the conductive metal sheet 19 is electrically connected to the conductive connection piece 25 of the switch body 24; the conductive block B17 is integrally formed with a limited position mounting cylinder 29; the conductive blocks A20 and B17 are correspondingly arranged at the bottom of the inner cavity of the mounting cavity; a gap is formed between the conductive blocks A20 and B17 and the inner side wall of the housing 12; the switch body 24 is correspondingly coaxially embedded in the lower part of the inner cavity of the limited position mounting cylinder 29, and its bottom is in contact with the conductive glass back cover 21. The pot piece 18 is correspondingly arranged within the inner cavity of the limited position mounting cylinder 29 and is located on the upper surface of the switch body 24.

[0028] The two spring plates 16 are respectively installed on the opposite sides of the rotating part 15; the bottoms of the opposite sides of the rotating part 15 are provided with positioning pin receiving holes, and positioning pins 35 are fixedly provided in the positioning pin receiving holes. One end of the spring plate 16 extends into the positioning pin receiving hole and is wrapped and connected with the positioning pin 35.

[0029] The rotating portion 15 is correspondingly sleeved on the outer side of the limit mounting cylinder 29; the lower portion of the axis 13 extends into the limit mounting cylinder 29 coaxially; waist-shaped limit holes 30 for the fixing pin 14 to pass through laterally are formed on opposite sides of the limit mounting cylinder 29, and the rotating portion 15 is formed with a limit groove 31 for receiving the fixing pin 14; the waist-shaped limit holes 30 form a space for the axis 13 to achieve vertical displacement;

[0030] An anti-slip pattern 22 is formed circumferentially on the inner side wall of the housing 12 at a position corresponding to the rotating portion 15 , and the free ends of the two spring plates 16 are in contact with the anti-slip pattern 22 .

[0031] Preferably, a guide ring 23 is coaxially formed on the upper surface of the shell 12, and the guide ring 23 extends into the inner cavity of the cap sleeve 10 and transitionally fits with the bottom of the axis fixing seat 11. Through such a structural setting, when pressing the operation, it is ensured that the cap sleeve 10 can be displaced along its axis, thereby improving the accuracy of the operation.

[0032] Preferably, an annular interlocking groove 32 is formed at the lower part of the inner wall of the cap sleeve 10 and at a position corresponding to the axial fixing seat 11, and the axial fixing seat 11 is correspondingly received in the annular interlocking groove 32; a plurality of grooves 33 are provided in a circumferential array on the outer side surface of the axial fixing seat 11. By providing a plurality of grooves 33, the contact area between the axial fixing seat 11 and the cap sleeve 10 is reduced, thereby reducing friction.

[0033] Preferably, the bottom end of the shaft 13 is configured as a conical contact surface 34. Through such a structural configuration, the contact area between the shafts 13 and 13 is reduced, thereby improving the service life.

[0034] In this embodiment, after the structure is attached to the touchscreen panel, the cap is manually rotated, and the inductance is transferred through the axis to conductive block B. The conductive glass back cover senses the inductance of conductive block B and follows the knob to decrease or increase. This eliminates the need for a fixed sensing area, allowing for fine-tuning in multiple levels, resulting in precise rotation. When the knob is pressed, the axis passes through the pot and the inductance is transferred to conductive block A. The conductive glass back cover senses this and confirms the function. Pressing the pot creates a pleasant pressing feel, ensuring the knob has a good control feel.

[0035] The above embodiment merely represents one embodiment of the present invention. While the description is relatively specific and detailed, it should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be determined by the appended claims.
