DESCRIPTION OF THE EMBODIMENTS

(8) Reference will now be made in detail to the present preferred embodiments of the invention, examples of which are illustrated in the accompanying drawings. Wherever possible, the same reference numbers are used in the drawings and the description to refer to the same or like parts.

(9) FIG. 1 is a schematic drawing of a switch structure according to an embodiment of the invention. FIG. 2 is a partial cross-sectional view of the switch structure of FIG. 1. Referring to FIG. 1 and FIG. 2 together, in the present embodiment, a switch structure 100 is used for switching on or off an electronic system 20. Herein, the electronic system 20 refers to various electronic devices or circuit systems applicable in general household. Here, the switch structure 100 includes a base 110, a switch body 120, a first electrode A1 and a second electrode A2, The first electrode A1 and the second electrode A2 are electrically connected to the electronic system 20, respectively. The second electrode A2 is disposed in the base 110, and the first electrode A1 is substantially attached on the switch body 120 and moved along with the switch body 120. As shown in FIG. 2, each of the first electrode A1 and the second electrode A2 is electrically connected to the electronic system 20 by respective terminal structures.

(10) The switch body 120 is, for example, a handle portion of a rocker switch substantially pivoted to the base 110 and can be forced to rotate and move so the first electrode A1 and the second electrode A2 can be switched between a conductive state (as shown in FIG. 2) and a non-conductive state. In the conductive state shown in FIG. 2, a user can have the switch body 120 rotated in clockwise direction by an applied force F such that the first electrode A1 and the second electrode A2 are moved away from each other in order to form the non-conductive state. Correspondingly, if the applied force F is applied to a left side of the switch 120 in the non-conductive state, the conductive state may again be switched back to the conductive state shown in FIG. 2.

(11) FIG. 3 is a schematic drawing for assembling a part of components in the switch structure of FIG. 1. FIG. 4 is a simple side view of the components of FIG. 3 after assembly is completed. Referring to FIG. 2 to FIG. 4 together, specifically, in the present embodiment, the switch structure 100 further includes a torsion assembly 130, an engaging member (141, 142) and a power source 150. As shown in FIG. 3, the torsion assembly 130 includes a reducing gear 131, a driving gear 132, a transmitting shaft 133 and an interlocking piece 134. The power source 150 is, for example, a motor, which includes a main body 151 and a screw rod 152 (or a worm gear). As shown in FIG. 3 and FIG. 4, the screw rod 152 is meshed with a transmitting tooth 131b of the reducing gear 131, and the reducing gear 131 further includes a transmitting tooth 131a, which is concentrically disposed together with the transmitting tooth 131b and meshed with a transmitting tooth 132d of the driving gear 132. In this way, a driving force generated by the power source 150 may be transmitted to the driving gear 132 via the screw rod 152 and the reducing gear 131. It should be noted that, since contour outlines of the gears are well-known knowledge in the related art, the gear components are all illustrated by simplified diagrams in the drawings of the present application.

(12) Moreover, the driving gear 132 further includes an opening 132b and an accommodating slot 132a (with contour of an expanding hole), and the transmitting shaft 133 includes a first shaft portion 133a, a second shaft portion 133b and a third shaft portion 133c which are coaxially disposed and have different contours and outer diameters. The second shaft portion 133b and the third shaft portion 133c are inserted to the opening 132b. The second shaft portion 133b is located inside the opening 132b such that the third shaft portion 133c is passed outside the opening 132b, and the first shaft portion 133a leans against the accommodating slot 132a. It should be noted that, the driving gear 132 further includes fitting slots 132c located at a periphery of the accommodating slot 132a and corresponding to each other, and the engaging pieces 141 and 142 are elastic pieces embedded in the fitting slots 132c for leaning against two opposite lateral edges of the first shaft portion 133a. Here, the first shaft portion 133a may be regarded as a rectangular block, with two opposite sides clamped by the engaging members 141 and 142.

(13) On the other hand, the transmitting shaft 133 further includes a turning hole 133d located on the third shaft portion 133c. A first end E1 of the interlocking piece 134, which is a flat piece, is inserted to the turning hole 133d (i.e., a contour of the turning hole 133d can fit in the first end E1 of the interlocking piece 134). A second end E2 of the interlocking piece 134 is inserted to a shaft hole 121 of the switch body 120. Therefore, when the transmitting shaft 133 rotates, the switch body 120 can be driven to rotate by the interlocking piece 134. Relatively, when the power source 150 conducts a backwards driving, the transmitting shaft 133, the interlocking piece 134 and the switch body 120 may also rotate backwards.

(14) Accordingly, when the power source 150 provides power to drive the reducing gear 131 and the driving gear 132 for rotation, the transmitting shaft 133 may be driven to rotate by the engaging members 141 and 142. In this way, the switch body 120 and the first electrode A1 can be driven to move and switch between the conductive state and the non-conductive state in order to achieve the purpose of switching on or off the electronic system 20.

(15) FIG. 5 is a schematic diagram of an electrical connection of the switch structure of FIG. 1. The switch structure 100 further includes a control module 160, which is electrically connected to the power source 150 so the user can set up conditions for the control module 160 to switch on or off the power source 150 accordingly, thereby achieving a desired switching effect. In addition, the control module 150 is also adapted to receive a wireless signal of a remote device 30 and accordingly switch on or off the power source 150. As such, the user is able remotely control the switch structure 100 to achieve a smart home effect.

(16) Referring back to FIG. 3 and FIG. 4, when the power source 150 cannot be started due to power failure, the user can still manually provide the applied force F to the switch body switch 120 so as to decide the effect of switching on or off for the switch structure 100. More specifically, because the engaging members 141 and 142 are the elastic pieces, when the applied force F is provided to the switch body 120, the transmitting shaft 133 is driven by the interlocking piece 134 so the first shaft portion 133a (the rectangular block) of the transmitting shaft 133 can overcome a clamping effect of the engaging members 141 and 142 on the transmitting shaft 133 by a greater power. Accordingly, the engaging members 141 and 142 may be expanded outwardly so the engaging members 141 and 142 can closely lean against the two opposite lateral edges of the first shaft portion 133a respectively at top and down positions, as shown in FIG. 4. Therefore, when the applied force F drives the transmitting shaft 133 to rotate, the first shaft portion 133a (the rectangular block) can open up the engaging members 141 and 142 respectively in upward and downward directions and continue to rotate. Until the applied force F is stopped after the rotation reaches 90 degrees, the engaging members 141 and 142 can lean against the two opposite lateral edges of the first shaft portion 133a again due to elastic recovery. Accordingly, the situation where the switch structure 100 cannot be switched on or off due to the power failure or malfunction of the control module 160 and the power source 150 may be solved.

(17) FIG. 6 and FIG. 7 are schematic partial views of different embodiments of the invention, respectively. Only relevant components are illustrated here with reference to FIG. 4. With reference to FIG. 6, in the present embodiment, three engaging members 441, 442 and 443 are disposed on a driving gear 432, and (a first shaft portion of) the transmitting shaft is a six-sided pillar. The engaging members 441, 442 and 443 lean against three pillar surfaces on the six-sided pillar, and have pushing forces with respect to the transmitting shaft in a balanced state. Accordingly, aside from achieving a clamping relation between the transmitting shaft 133 and the engaging members 141 and 142 as described above, the effect of switching on or off in a manual state may be also be achieved by driving the transmitting shaft 432 to deform the engaging members 441, 442 and 443. However, the difference is that, a rotation angle of a transmitting shaft 433 in the present embodiment is smaller (which is 90 degree in the foregoing embodiment, and 60 degrees in the present embodiment), so a power saving (including the applied force F or electrical power required by the power source 150) effect can be achieved. Similarly, a transmitting shaft 533 shown in the embodiment of FIG. 7 is similar to the rectangular block of the FIG. 4, and the difference is that there are four engaging members 541, 542, 543 and 544 respectively leaning against four side edges of the rectangular block. In addition to a larger clamping force provided for the transmitting shaft 533, this approach can also maintain the same driving effect as described above even if one of the engaging members is malfunction.

(18) In summary, in the foregoing embodiments of the invention, by disposing the torsion assembly in the switch structure, the torsion assembly may be connected between the switch body and the power source. Accordingly, in the automatic state, the power source drives the torsion assembly to provide the torsion to the switch body so different rotating positions of the switch body can have the first electrode and the second electrode in the base close connected to or moved away from each other. In this way, electrical conduction or electrical open circuit (where current cannot pass through) may be provided to switch on or off the electronic system.

(19) Furthermore, in the switch structure, the engaging member is disposed on the driving gear of the torsion assembly and clamps the transmitting shaft of the torsion assembly, and the transmitting shaft is further connected to the switch body by the interlocking piece. Accordingly, in the automatic state, when the power provided by the power source is driving the torsion assembly, the transmitting shaft may be clamped by the engaging member to transmit the power to the switch body. Meanwhile, because the engaging member is elastic, when the power source is not switched on yet, the user can still apply force on the switch body so the deformation of the engaging members can be overcame by the applied force, allowing the transmitting shaft to successfully rotate, thereby achieving the purpose of switching on or off the electronic system.

(20) As a result, the switch structure is provided with operation modes such as the automatic (powered) state and the manual state to achieve effectiveness of improving use convenience and wide application range.

(21) It will be apparent to those skilled in the art that various modifications and variations can be made to the structure of the present invention without departing from the scope or spirit of the invention. In view of the foregoing, it is intended that the present invention cover modifications and variations of this invention provided they fall within the scope of the following claims and their equivalents.
