Description

Technical Field

[0001] This utility model relates to a control switch panel, and in particular to the structure of a rotary switch panel. Background Technology

[0002] Switch panels are essential components used to connect circuits and control their on / off states. Traditional switch panels have a mechanical structure, where a button actuates a metal plate to control the circuit. However, with technological advancements and the increasing prevalence of smart homes, electronic panels are becoming more common. Existing electronic panels mainly include touch panels and rotary panels. The former is controlled by pressing a switch or touchscreen, while the latter controls the circuit by turning a button. Touch panels have a relatively simple function, while rotary panels have a more complex structure, and many components require adhesives. This requires waiting for the adhesive to dry and solidify, making production operations more complex and less efficient. Furthermore, the use of adhesives can easily cause other substances to stick, affecting environmental hygiene and hindering worker operations. Utility Model Content

[0025] This utility model proposes a rotary switch panel structure.

[0026] The rotary switch panel structure of this embodiment includes a base box 1, a cover plate 2 disposed on the outer side of the base box, and a rotatable knob 3; the cover plate has an annular groove 21 with a circular recess in the middle, and the cover plate is positioned on a positioning platform 22 located inside the annular groove. The control circuit board 4 is installed on the positioning platform, and the control circuit board is equipped with a toggle switch 5 that can be elastically reset. The cover plate has a bearing 6 fitted on the outer side of the positioning platform at the annular groove. The knob is installed on the bearing, and the knob has a circular hole in the middle. The inner wall of the circular hole is provided with a plurality of protruding teeth 31 along the circumference. The end of the toggle switch is located at the tooth groove of the adjacent teeth.

[0027] like Figure 1-6 As shown, the main control circuit board is installed inside the base box. A cover plate is installed on the outer side of the base box, i.e., the side facing the user. The cover plate has an annular groove in the middle, forming a disc-shaped positioning platform in the middle of the cover plate. The inner ring of the bearing is fixedly fitted onto the circular outer wall of the positioning platform, and the knob is fixed relative to the outer ring of the bearing, allowing the knob to rotate relative to the base box and the cover plate. A control circuit board connected to the main control circuit board is also installed on the positioning platform. The toggle switch on the control circuit board generates a control signal by being toggled, and the end of the toggle switch is elastic, so that it can be reset after each toggle and drive the next toggle. The inner wall of the circular hole in the middle of the knob is provided with teeth along the circumference, so that the toggle switch can be controlled by the teeth when the knob is rotated. As the knob continues to rotate, the end of the toggle switch is continuously toggled, thereby generating a continuous control signal.

[0028] like Figure 4 , 5As shown, there is a gap between the bearing 6 and the bottom of the annular groove 21. Several positioning strips 32 that fit against the outer wall of the positioning platform 22 and several elastic knob hooks 33 extend from the round hole of the knob 3. The ends of the knob hooks are located in the gap between the bearing and the bottom of the annular groove and are locked and fixed to the bearing. This connection structure is relatively simple, but the connection strength is high and it can be easily installed and disassembled. When disassembly is required, the bearing can be pushed out by simply prying open the knob hooks. When reinstallation is required, the bearing can be pushed in directly.

[0029] The rotary switch panel structure includes a mounting platform 7 between the positioning platform 22 and the control circuit board 4. The positioning platform has several screw holes, and the control circuit board and mounting platform have through holes opposite to these screw holes. Fixing screws (not shown) pass through these through holes and are screwed into the screw holes. The inner side of the bearing 6 is simultaneously fitted onto both the positioning platform and the mounting platform. This improves the ease of assembly and disassembly of parts and enhances the installation strength of the bearing, thereby improving the working stability of the rotary switch. The control circuit board 4 has several bayonet slots, and the mounting platform 7 has mounting hooks 71 that are fixed to some of these slots. Simultaneously, a baffle 8 is provided inside the round hole of the knob 3 and outside the control circuit board 4. A locking block 72 is provided on the mounting platform 7 opposite to some of the bayonet slots of the control circuit board 4, and the baffle has a locking hook 81 that is fastened to the locking block, further improving the installation stability of the control circuit board. Additionally, as... Figure 4 , 6 As shown, a display screen 9 is mounted on the outer side of the baffle 8. The display screen is connected to the control circuit board 4 and displays operating signals, such as the power setting of the electrical appliance or ambient temperature and humidity. Furthermore, a ring-shaped sleeve 10 is detachably mounted on the knob 3, while a decorative panel 11 is mounted on the outer side of the cover plate 2. Different sleeves and decorative panels can create different appearances to suit various occasions and decorating styles. The surface of the sleeve 10 is provided with anti-slip stripes to improve operational comfort. The display screen 9 is located in the circular hole in the center of the sleeve, further enhancing the overall aesthetics.
