Detailed Description

As shown in fig. 1, the switch-type self-generating system comprises a generating coil module 1, which at least comprises a coil 2 and a magnetic conductive core 3 in the coil 2. The coil 2 generates current by inducing a change in magnetic flux in the magnetically permeable core 3, and for this purpose, the invention provides a movable bracket 4 on the power generation coil module 1, and a magnetic body 5 is provided on the movable bracket 4, and the magnetic flux is changed by bringing different magnetic poles of the magnetic body 5 into contact with the magnetically permeable core 3. The movable support 4 has the following specific structure: one end is provided with a rotating shaft, and is connected with the power generation coil module 1 through the rotating shaft; the other end is a free end, the free end is connected with the switch device 6, when the switch device 6 moves, the free end drives the movable support 4 to swing around the rotating shaft, the magnetic body 5 is fixed on the free end, and two poles of the magnetic body 5 are respectively contacted with the magnetic conductive core 3 during swinging. But generates less power by induction and is therefore generally suitable for use with electronic devices that use less power. Because the whole system does not need to be powered by a battery or mains supply, a fully-sealed structure can be adopted for the circuit part, so that the influence of the humid environment in facilities such as a bathroom or a bathroom door lock on the service life of the circuit part is avoided, and if the system is not in fault, the system is not required to be maintained, and the maintenance work and the cost are greatly reduced.

As shown in fig. 2 and 3, specifically, the magnetic body 5 is sandwiched between two magnetic conductive sheets 7 so as to form a space between the two magnetic conductive sheets 7 for accommodating movement of the magnetic core, the end of the magnetic conductive core 3 is placed in the space, and the end of the magnetic conductive core 3 is attracted to one of the two magnetic conductive sheets 7 in response to swinging of the movable bracket 4, thereby changing the magnetic flux of the magnetic conductive core 3. The magnetic conducting sheet 7 also limits the swing range of the movable support 4, so that the magnetic conducting core 3 can be effectively attracted with one of the two magnetic conducting sheets 7.

As described above, the system generates smaller electric quantity, which is generally only suitable for electric equipment with lower energy consumption, and the power supply of the system also occurs at the moment of the change of the switch state, so that the system is more suitable for transmitting the signal of the change of the switch state to a server or controlled equipment. For this purpose, the electric equipment of the present invention is preferably at least one group of wireless signal transmitting circuits, and when the coil 2 senses the generated electric quantity, the wireless signal transmitting circuits are activated and generate wireless signals to be transmitted to the server or the controlled device, so that the server or the controlled device can record the state of the switch or make corresponding operations, etc. The coil 2 generates positive or negative pulse according to the variation and direction of the magnetic flux of the magnetic core 3, and at least the pulse needs to be rectified to supply power to the wireless signal transmitting circuit, so as to prevent the reverse pulse from entering the wireless signal transmitting circuit and possibly causing breakdown. If necessary, a filter circuit can be added, the peak value of the pulse signal with higher voltage output by the coil 2 instantaneously can be reduced, the wireless signal transmitting circuit is damaged by high voltage, and meanwhile, the peak value voltage is temporarily stored to maintain longer power supply time.

Because of the interruption of power supply and small electric quantity, even if a low-power wireless signal transmitting circuit is used, the circuit can only be kept working for a short time. In the practical use process, the wireless signal transmitting circuit can only send a control signal generally due to very short working time, and the server or the controlled device cannot actually judge what state the switch is in through the signal, for example, the signal transmitted by the switch when the switch is possibly switched to one of the states is lost, and the like, which can cause the server or the controlled device to work confusedly. In order to avoid the problems, the invention preferably adopts two groups of wireless signal transmitting circuits, the two circuits are respectively connected to the positive half-cycle rectifying circuit and the negative half-cycle rectifying circuit, namely, the electric quantity generated when the magnetic conducting core 3 is contacted with different magnetic poles of the magnetic body 5 is respectively supplied to different wireless signal transmitting circuits, and the different wireless signal transmitting circuits send different control signals to the receiving equipment, so that the server or the controlled equipment can accurately judge the working state of the switch through the different control signals.

The plectrum mechanism 8 is rotatably arranged through a rotating shaft, and the plectrum mechanism 8 is connected with the free end of the movable bracket 4. When the lock is used, the lock body is opened or closed, the lock tongue 9 can slide in different directions, so that the movable support 4 swings left and right, and accordingly currents in opposite directions are generated in the coil 2 and used for driving different wireless signal transmitting circuits to transmit different control signals. Specifically, the paddle mechanism 8 includes a driving surface 10 that abuts against the lock tongue 9 of the lock body, and the driving surface 10 of the paddle mechanism 8 is magnetically attracted to the contact surface between the driving surface 10 and the lock tongue 9 so that the lock tongue 9 can be driven in different sliding directions. In addition, in order to prevent the travel of the lock tongue 9 from exceeding the non-movable range of the movable bracket 4 and damaging the movable bracket 4, a limiting surface 11 for limiting the rotation angle of the shifting plate mechanism 8 is further arranged on the shifting plate mechanism 8, and the limiting surface 11 and the driving surface 10 are configured to form an included angle, so that different movable ranges are realized through different included angles. When the stop surface 11 contacts the tongue 9, the rotation of the dial mechanism 8 is restricted to restrict the tongue 9 from sliding within a proper range.

For this purpose, another magnetic body 15 is provided on at least one of the lock body and the tap handle 14, and the tap handle 14 is attracted by the magnetic body 15 to sufficiently move the lock body to the closed state.
