Description

BRIEF DESCRIPTION OF THE DRAWINGS

(1) FIG. 1 is an exploded view of a new-type multiple knob structure in accordance with an embodiment of the disclosure.

(2) FIG. 2 is a pressing diagrammatic drawing of a new-type multiple knob structure in accordance with an embodiment of the disclosure.

(3) FIG. 3 is a rotating diagrammatic drawing of a new-type multiple knob structure in accordance with an embodiment of the disclosure.

DETAILED DESCRIPTION

(4) In order to fully comprehend the features and efficacy of the present disclosure, a detailed description is described by the following substantial embodiments in conjunction with the accompanying drawings. The description is as below.

Embodiment 1

(5) Referring to FIG. 1, an exploded view is provided of a new-type of multiple knob structure in accordance with an embodiment of the disclosure. The disclosure provides a new-type multiple knob structure.

(6) The knob structure comprises a knob top module 1, a bearing module 2 and a knob bottom module 3.

(7) Therein the knob top module 1 includes a head cover 11, a silicone keyboard 12, and a head annular PCB 13 from top to bottom; the bearing module 2 includes a bearing holder 21 and a bearing 22; the knob bottom module 3 includes a bottom cover 31 and a bottom PCB 32.

(8) More particularly, the knob bottom module 3 also includes a torsional spring 33 and a rotation damper 34; the torsional spring 33 is mounted on an installing groove 311 of the bottom cover 31; the rotation damper 34 is mounted on a rotation damper installing groove 312 of the bottom cover 31.

(9) The vertical press function is set up on the head annular PCB 13 and the rotation function is setup on the bottom PCB 32. This simplifies the integration manufacturing procedure of the PCB and it achieves different functions on different places of the knob. It optimizes knob structure and improve consumer's experience when vertical pressing and rotating the knob.

(10) In this embodiment, the bearing 22 is mounted on a bearing seat 313 of the bottom cover 31, the bearing seat 313 is setup on the middle axle of the bottom cover 31.

(11) Now referring to FIG. 3, a rotating diagrammatic drawing is provided of a new-type of multiple knob structure in accordance with an embodiment of the disclosure. To further describe the rotation function of the invention, the bearing 22, the torsional spring 33, and the rotation damper 34 are setup on the knob structure jointly. When rotating the knob clockwise or anticlockwise 30 degrees, it will trigger the knob to work and the knob would springback automatically under the action of the torsional spring 33 and the rotation damper 34.

(12) For ease of illustration, a vertical press module is also provided by the disclosure, it is comprised of a head cover 11, a silicone keyboard 12, a head annular PCB 13, and a bearing holder 21;

(13) The vertical press module is mounted on a periphery of the bearing 22. To further describe the location of the vertical press module, it is mounted on the bottom cover 31 with bolts.

(14) Turning now to FIG. 2, a pressing diagrammatic drawing is provided of a new-type multiple knob structure in accordance with an embodiment of the disclosure. In this embodiment, nine pieces of button 121 are setup on the silicone keyboard 12, nine pieces of button triggers 131 are setup on the head annular PCB 13. It will be understood by those skilled in the art, that the nine pieces of buttons 121 correspond to the nine pieces of button triggers 131.

(15) A slide switch 321 is setup on the bottom PCB 32 of the knob bottom module 3 as illustrated in FIG. 1. The slide switch 321 triggers the knob to rotate.

(16) The new-type multiple knob structure provided by the invention is suitable for applying in knobs with varisized diameters, meanwhile its structure is simple and only a single bearing with lower cost is setup as the main bearing structure. Therefore, it can meet the requirements of the knob structure's application on electrical switch and regulating equipment.

(17) The present invention is disclosed by the preferred embodiment in the aforementioned description; however, it is contemplated for one skilled at the art that the embodiments are applied only for an illustration of the present disclosure rather than are interpreted as a limitation for the scope of the present invention. It should be noted that the various substantial alternation or replacement equivalent to these embodiments shall be considered as being covered within the scope of the present invention.
