The subject is in an open or closed state. Although the above-described lid detecting device using the magnetic body and the magnetic detecting switch can judge that the lid body is in an open or closed state, it uses a magnetic body and a magnetic detecting switch of 6 丄J厶J丄J厶丄J丄J丄叶厶The components are complicated. Moreover, it is necessary to cooperate with subsequent circuits, and the structure is relatively more. [Inventive content] * In view of the above, it is necessary to provide an opening and closing detecting device having a simple structure. Further, it is also necessary to provide a control system using the opening and closing detecting device. An opening and closing detecting device 'includes a cover body, a body, and a detecting unit. Φ The detecting unit includes a top contact portion and a top touch switch, the top contact portion is disposed on the cover body and located on a side of the cover body connected to the body; the top touch switch is disposed inside the body and the The corresponding position of the top contact. The body is provided with an opening. The top contact extends through the opening into the interior of the body. The top contact portion can trigger the top touch switch to generate a corresponding rotation state detection signal as the cover body rotates relative to the body. A control system includes an opening and closing detecting device and a controller, the opening and closing detecting device comprising a cover body, a body, a top contact portion and a top touch switch. The top contact portion is disposed on the cover body and located on a side of the cover body connected to the body; the top touch switch is disposed at a position corresponding to the top contact portion inside the body. The body is provided with an opening through which the top portion projects into the interior of the body. The top contact portion can trigger the top touch switch as the cover body rotates relative to the body, and the controller generates a corresponding control signal according to the detection signal sent by the top touch switch. The opening and closing detecting device can respectively provide a top touch switch on the main body and the cover body and a top contact portion for triggering the top touch switch, which can directly obtain an opening or closing signal of the cover 7 1325142 relative to the main body, and the above control system is The opening or closing signal from the opening and closing detection device sends a corresponding control signal, and the structure is simplified. [Embodiment] Please refer to Fig. 1, which is a schematic view showing the structure of an opening and closing detecting device of a preferred embodiment. The opening and closing detecting device 20 includes a cover 22, a body 24, a pivoting mechanism 26, a detecting unit 28, and the like. The cover 22 is coupled to the body 24 by a pivoting mechanism 26 such that the cover 22 is rotatable relative to the body 24 about the pivoting mechanism 26. The detecting unit 28 is disposed at the intersection of the cover 22 and the body 24 to detect the state in which the cover 22 is opened or closed relative to the body 24. Please refer to Fig. 2' which is an exploded view of the opening and closing detecting device 2' shown in Fig. i. The detecting unit 28 includes a top contact portion 282 and first and second top contact switches 284, 286 and the like. The top contact portion 282 is disposed on the cover body 22, and is located on the same side of the cover body 22 as the pivot mechanism 26, and extends into the interior of the body 24 through an opening 322 provided in the body 24. The first and second top touch switches 2 are mounted on the inside of the body 24 at 286. The top contact portion 282 can trigger the first and second top touch switches 284, 286 to rotate with the cover 22 relative to the body 24 to generate a corresponding detection signal. 3 and FIG. 4' is a schematic structural view of the top contact portion 282 of the detecting unit 28 shown in FIG. 2; FIG. 4 is a side view of the detecting unit 28 shown in FIG. 2. The top contact portion 282 includes An action portion 292, a second action portion 294, and (four) track first-operating portion Μ2 and second action portion Μ4 are arranged along the axial direction of the yoke 8 1325142, respectively, for triggering the first and second top touch switches 284, 286. The shaft core 296 is substantially parallel to the cover body 22, and is disposed coaxially with the pivot mechanism 26, and is connected to the first and second action portions 292, 294, and thus the first and second action portions 292 and 294 The shaft core 296 can be pivoted. The detecting unit 28 further includes a sleeve 324 disposed on the body 24, and the shaft core 296 extends through the opening 322 (see FIG. 2) of the body 24 into the body 24, and The top contact portion 282 is rotatable about the shaft core 296 and the sleeve 324. The first action portion 292 and the second action portion 294 extend from the cover body 22 in a direction perpendicular to the cover body 22. And the arc core 296 is bent in a circular arc shape to form a circular arc side wall. Thus, the first and second action portions 292 and 294 respectively The central core 296 has a fan-shaped shape, and the central angles corresponding to the two segments are different, and the central angle corresponding to the first operating portion 292 is slightly larger than the central angle corresponding to the second operating portion 294. The operating portions 292 and 294 respectively have first and second movable surfaces 306 and 308. The first and second operating surfaces 306 and 308 are respectively a radius surface of each of the segments, and are respectively tangent to the core 296. The first and second action surfaces 306, 308 and the cover body 22 are respectively disposed at a first and second predetermined angles, so that the first action surface 306 and the second action surface 308 are also at a predetermined angle. The second action surfaces 306, 308 are respectively for contacting the first and second top touch switches 284, 286. Preferably, the first and second action surfaces 306, 308 are substantially perpendicular to the cover 22, the first predetermined The angle is slightly greater than 90°' and the second predetermined angle is slightly less than 90. This allows the first and second movements 1325142 to face substantially perpendicular to the body 22 of the cover 22' when the cover 22 is closed. And in the direction parallel to the cover 22, the body 24 and the top when it is rotated The switches 284, 286 are in contact with each other to facilitate the setting of the top touch switches 284, 286. * In conjunction with Figures 2 and 4, the first and second top touch switches 284, 286 respectively include first and second sensing portions 312, 314 and The first and second bases 316 and 318 are respectively fixed to the first and second bases 316 and 318; the other ends are respectively used for the top contact portion 282. The spring first operation unit 292 and the second operation unit 294 are in contact with each other to sense whether the first and second operation portions 292 and 294 are rotated by the cover 22 to a predetermined position. Thus, the first and second top touch switches 284, 286 can detect the rotation state of the cover 22 relative to the body 24 and issue a corresponding detection signal. The first and second bases 316, 318 are received inside the body 24 and are arranged on the body 24 along the axial direction of the core 296. Corresponding to the position where the first action surface 3〇6 and the second action surface 308 are rotated about the axis 296, the first and second top touch switches 284, 286 are staggered in a direction perpendicular to the axial direction _s Set. Therefore, when the first and second action portions 292, 294 are rotated perpendicular to the axial direction of the shaft core 296, the first and second action faces 3〇6, 3〇8 can be in the direction perpendicular to the axial direction. The first and second sensing portions 312, 314 are simultaneously extruded. Next, the structure of the detecting unit 28 in the two states in which the cover 22 is in the process from opening to closing with respect to the body 24 will be described with reference to Figs. As shown in FIG. 4, when the cover 22 is in an open state with respect to the body 24, the cover 22 and the body 24 are at an angle, and the top contact portion 282 is separated from the first and second top contact switches 284 and 286. Thus, the first and second top touch switches 284, 286 can emit a first 1325142 status signal so indicating that the cover 22 is in an open state. Referring to Fig. 5', it is a schematic structural view of the detecting unit 28 when the cover 22 is in a closed state with respect to the body 24. At this time, the lid body 22 is rotated to a position substantially parallel to the main body 24, and the first action portion and the second action portion 292, 294 are substantially perpendicular to the body 24, thereby respectively The first touch portion 312 and the second touch portion 314 of the first top touch switch and the second top touch switch 284, 286 are in contact with each other. The first and second sensing portions 312 314 are urged to the first and second action surfaces 306, 308 in a direction parallel to the body 24 and perpendicular to the axial direction of the shaft core 296. The switches 284, 286 are respectively activated to emit a second state signal SC indicating that the cover 22 is in a closed state. Please refer to FIG. 6, which is a schematic structural diagram of a control system 80 using the detecting unit 28 of the preferred embodiment. The control system 8A includes first and second top touch switches 284, 286 and a state determination module 8A2, a controller 8A4, and the like. The state determination module 802 determines the state of the cover 22 of the opening and closing detection device 2 relative to the body 24 according to the state signals SO, SC issued by the first and second top touch switches 284, 286, and transmits the status message. Go to controller 8〇4. The controller 804 sends a control signal to the controlled plant 70 based on the received status message. The controlled plant 70 can be a display unit of a display unit portable media player for a portable computer or a mobile phone, a spindle motor of the optical disk drive, and the like. Referring to Figure 7, it is a flow chart of the control system shown in Figure 6 using the detection signals from the detection unit 28 for control. First, step 902' state determination module 8 接收 2 receives detection signal S1 issued by first top touch switch 284. 11 1325142 Step 904, the state determination module 802 receives the detection signal S2 sent by the second top touch switch 286. In step 906, the state determination module 802 determines whether the received detection signal _ - S1 is the first state signal SO or the second state signal SC. If it is the first state signal SO, step 908 is performed; if it is the second state signal SC, step 910 is performed. In step 908, the state determination module 802 determines whether the received detection signal S2 is the first state signal SO or the second state signal SC. In step 912, if the state determination module 802 determines in step 908 that the detection signal S2 is the first state signal SO, the controller 804 issues a first control signal. Step 914, if the state determination module 802 determines in step 908 that the detection signal S2 is the second state signal SC, the controller 804 issues a second control signal. In step 910, the state determination module 802 determines whether the received detection signal, S2, is the first state signal SO or the second state signal SC. In step 916, if the state determination module 802 determines in step 910 that the detection signal S2 is the first state signal SO, the controller 804 issues a third control signal. Step 918, if the state determination module 802 determines in step 910 that the detection signal S2 is the second state signal SC, the controller 804 issues a fourth control signal. In the application, the detection signals sent by the two top-touch switches 284 and 286 may be different. Alternatively, the controller 804 may cause the control signal to be sent only when the two detection signals are the same at 12 1325142. When the detection signals are different, the state of the cover 22 relative to the body 24 is considered to be indefinite without issuing a control signal. • When the control system 80 is applied to control the spindle motor of the optical disk drive, the setting can be performed: the rotation of the spindle motor is started only when the detection signals of the two top contact switches 284, 286 indicate that the cover 22 is closed. As long as there is a detection signal of the top touch switch indicating that the cover 22 is opened, a control signal is issued to stop the rotation of the spindle motor. In this way, it is possible to effectively ensure that the motor rotates only when the cover 22 is closed, thereby avoiding the danger that the motor that rotates at a high speed is not covered, which makes the opening and closing detection more effective. The above-mentioned opening and closing detecting device can respectively provide a top touch switch and a top contact portion for triggering the top touch switch on the main body and the cover body, and can directly obtain a corresponding opening signal or a closing signal when the cover body rotates relative to the body. The structure is simplified. The above-mentioned opening and closing detecting device has a top touch switch disposed inside the body, and triggers the top contact portion of the top touch switch to extend into the body through an opening provided on the body, so that the trigger top contact switch can only be The inside of the body is carried out, thereby reducing the influence of external interference on it, and ensuring the stability and reliability of the opening and closing detecting device. In summary, the present invention complies with the requirements of the invention patent, and proposes a patent application according to law. However, the above is only a preferred embodiment of the present invention, and equivalent modifications or variations made by those skilled in the art of the present invention should be included in the following claims. 13 [Brief Description of the Drawings] FIG. 1 is a schematic structural view of an opening and closing detecting device of a preferred embodiment. - Figure 2 is an exploded view of the opening and closing detecting device shown in Figure 1.
