The accompanying drawings are included to provide a further understanding of the invention, and are incorporated in and constitute a part of this specification. The drawings illustrate embodiments of the invention and, together with the description, serve to explain the principles of the invention.
The switch structure 100 includes a main body 120, a switching member 110, an electrical conduction module 140, a control module 150 and a force coupling assembly 130. The main body 120 includes a frame 122 and a front cover 124 fitted in the walls, wherein the frame 122, for example, is constituted by a synthetic resin molded rectangular box with an opening at the front surface, the frame 122 is adapted to be fitted in the wall and used for housing other components. The front cover 124 is used to partially cover the opening at the front surface of the frame 122 and exposed at the wall surface. The switching member 110, for example, is a handle part of a rocker switch, and is pivoted at the top 122a of the frame 122 to be located rockabilly at a central opening of the front cover 124. That is to say, the switch structure 100 only has the switching member 110 exposed through a wall of the front cover 124 and the external appearance is similar to a conventional household switch structure. A user is able to directly exert an applied force F on the switching member 110 (applied force F may be applied to the left side and right side of the switching member 110 as shown in
More specifically, the switching member 110 of the present embodiment is rendered in a “T” shape structure, and includes a pressing part 112, a abutting arm 116 and a pivoting part 114 connected between the pressing part 112 and the abutting arm 116. The pivoting part 114 is pivoted at the top 122a of the frame 122 and the pressing part 112 is located at the central opening of the front cover 124 to receive the applied force F, such that the switching member 110 swings in the main body 120 through the pivoting part 114 to achieve a switch effect. The electrical conduction module 140 which is disposed in the frame 122 of the main body 120 includes an electrical conduction portions 142 and 146. The electrical conduction portion 142, for example, is a spring (reed plate) structure, having two opposite ends E1, E2. The end E1 is fixed at the bottom 122b of the frame 122 and is electrically connected to the electronic system 20. The end E2 extends from the end E1 and forms a cantilever structure (when not abutted by the switching member 110, described later). Furthermore, the electrical conduction portion 146 is fixed at the bottom 122b of the frame 122 and is electrically connected to the electronic system 20; the electrical conduction portion 146 and the electrical conduction portion 142 correspond together at the contact 144 located at the end E2.
In other words, the end E2 of the electrical conduction portion 142 is located movably between the switching member 110 and the electrical conduction portion 146; the electrical conduction portion 142 is located on a pivoting path (swing path) of (the abutting arm 116 of) the switching member 110; and the electrical conduction portion 146 is located on the moving path of the contact 144 of the electrical conduction portion 142. In this way, when the user exerts an applied force F on the pressing part 112 of the switching member 110, the switching member 110 is driven to pivot relative to the main body 120, such that the abutting arm 116 abuts the end E2 of the electrical conduction portion 142 so the end E2 moves closer to the electrical conduction portion 146 due to elastic deformation, and making the contact 144 and the electrical conduction portion 146 abut together allowing the electronic system 20 to achieve an electrically conductive state to switch on or shut off the electronic system 20.
It should be noted, the force coupling assembly 130 is disposed in the fame 122 of the main body 120 and is electrically connected with the control module 150. In the present embodiment, the force coupling assembly 130 includes a power source 132 (for example a motor electrically connected with the control module 150) and a pair of driving components 134, 136. The control module 150 is adapted to receive a wireless signal of the remote control device 40 to activate the power source 132 accordingly. As shown in
As shown in
Opposing to this, when the direction D1 faces the pressing part 112 and the direction D2 points out of the page, then the driving component 136 pushes on the pressing part 112, and the driving component 134 rather is not. In this way, the abutting arm 116 swings towards the right side of the figure (namely, the switching member 110 of
It should also be noted, when the driving components 134, 136 are not pushing on the pressing part 112, the switching member 110 is in a state adapted to receive the applied force F to perform a switching action. In other words, in the switch structure 100 of the present embodiment, there is a working time when the driving components 134, 136 are in a state having no structural relation with the switching member 110, so as to prevent the force coupling assembly 130 from producing an interference between the applied force F. Namely, in one state of usage in the present embodiment, after the control module 150 completes the action of driving the switching member 110 by the force coupling assembly 130, the control module 150 will drive the force coupling assembly 130 such that the direction D1, D2 no longer face the pressing part 112. That is to say, the driving components 134, 136 retreat back into a safe range for the user to safely and smoothly control the switch structure 100 by the proximal control of the applied force F. Namely, the remote control will not force the proximal control to be switched on or shut off. Of course, in another state of usage, the switch structure 100 may be insured to maintain the same state (on or off) and not be affected by the external applied force F by allowing the force coupling assembly 130 to maintain the original position after driving of the switching member 110 is complete, namely the remote control will have enforcement power over the proximal control.
In addition, an electrical conduction module 240 of the present embodiment includes electrical conduction portions 242, 245 and 246, wherein the electrical conduction portion 242, for example, is a double sided spring (reed plate), wherein the center thereof is disposed at the bottom 122b of the frame 122 by the base 241. The base 241 is electrically connected with an electronic system 50, in which the electrical conduction portion 245, 246 are fixed to the bottom 122b respectively and are electrically connected to the electronic system 50. Furthermore, two opposite sides E3, E4 of the electrical conduction portion 242 have contacts 243, 244 respectively, which in a cantilever state when not abutted by the abutting arm 116 correspond to the electrical conduction portions 245, 246 of the switching member 110. As shown in
The driving components 334, 336, for example are sliding blocks, slidably disposed in the rails R1, R2 in the main body 320 respectively, and connected at two opposite ends of the lever 331 respectively. The lever 331 is pivoted at the main body 320; the power source 332 is connected at the lever 331 to drive the lever 331 to pivot about an axis L2. When the lever 331 rotates about the axis L2, the driving components 334, 336 are driven to move under the switching member 310 along the rails R1, R2 at different working times respectively.
More specifically, using the driving component 334 as an example, as shown in
In the present embodiment, the sliding blocks are disposed next to the switching member 310, and the axis L2 does not pass through the switching member 310. Namely in this way, during a working time, the force coupling assembly 330 has no structural relation with the switching member 310 (as shown in
In the present embodiment, the rotating ring 433 is disposed on a ring gear 435 having the same axis (L3) to drive the rotating ring 433 to rotate synchronously. However, the structure of the power source driving the rotating ring 433 should not be construed as a limitation to the embodiment, and prior known transmission components which may allow the rotating ring 433 to achieve a rotation effect may be applied to the present embodiment.
In addition, in other embodiments of the invention not shown, the force coupling assembly may include a pair of driving components, namely a pair of protrusions, disposed on the surface of the rotating ring 433 facing the pressing part 412, in which the pair of protrusions and the axis L3 are not on the same diameter of the rotating ring 433. In this way, the rotating ring 433 is able to lower the rotation angle thereof through the disposition of the pair of protrusions. Therefore, wear on the power source may be lowered. In this way, under the premise without using the applied force F, a designer may lower the power output of the power source through disposing a plurality of driving components (protrusions) to achieve a conservation effect.
In summary, in the embodiments of the invention, the switch structure provides a driving mode by receiving an external force, and in addition the switching member may achieve an effect of switching on or shutting off of the electronic system through whether the electrical conduction portions are abutted or not through a remote control of the force coupling assembly. Furthermore, the force coupling assembly may achieve a switching effect by driving the switching member to pivot relative to the main body accordingly through the aforementioned cams of the same shaft, cams of different shafts, the lever driving the sliding blocks and protrusion structures on the rotating ring. The force coupling assembly may provide different effects according to the user's requirement such as conditions of not interfering with the external applied force or using interference to ensure an external applied force does not have an effect. Thus, the ranges of use for the switch structure are increased.
