technical field

Background technique

With the development of smart buildings, smart buildings and smart home industries, wireless communication has gradually begun to be used in buildings to control electrical equipment such as lamps, curtains, air conditioners, etc., especially the intelligent control of lamps, and the use of wireless control can reduce wire burial. Based on the above advantages, wireless control has gradually become an important means of electrical control such as lamps and lanterns.

At present, the commonly used wireless control methods are mainly based on technologies such as Bluetooth and Zigbee, using radio waves of 2.4GHZ or even higher frequency bands to transmit wireless signals. It is greatly reduced in the building, and it is necessary to increase the relay node device to solve the problem of insufficient control distance, which greatly increases the equipment and use costs, as well as the installation and maintenance difficulty. At the same time, the installation of the relay node device also needs to increase the power supply position. This will also compress the design space of the building.

Detailed ways

The following description serves to disclose the invention to enable those skilled in the art to practice the invention. The preferred embodiments described below are given by way of example only, and other obvious modifications will occur to those skilled in the art. The basic principles of the invention defined in the following description may be applied to other embodiments, variations, improvements, equivalents, and other technical solutions without departing from the spirit and scope of the invention.

It should be understood by those skilled in the art that in the disclosure of the present invention, the terms "portrait", "horizontal", "upper", "lower", "front", "rear", "left", "right", " The orientation or positional relationship indicated by vertical, horizontal, top, bottom, inner, outer, etc. is based on the orientation or positional relationship shown in the drawings, which is only for the convenience of describing the present invention and to simplify the description, rather than to indicate or imply that the device or element referred to must have a particular orientation, be constructed and operate in a particular orientation, and thus the above terms should not be construed as limiting the invention.

It should be understood that the term "a" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element may be one, while in another embodiment, the number of the element may be one. The number may be plural, and the term "one" should not be understood as a limitation on the number.

In an application such as a home, office or hotel, there are usually no more than 30 lamps that need to be controlled by the user. For the wireless switches of the prior art, if the indoor wireless switches are operated at different times, although there are a large number of them, even though they are at the same wireless frequency, the control signals of the wireless switches will not interfere with each other and conflict with each other, nor will they The signal jam occurs, but as shown in Figure 1, where S11 and S21 are wireless switches, C1 and C2 are receiving controllers, and L1 and L2 are loads. If two or more of the wireless switches are operated at the same time, And the wireless switch transmits the control signal through the same wireless frequency, then the signals transmitted by the two wireless switches will overlap in time, so mutual interference will occur, and the control of each wireless switch may fail. . In real life, this situation may be due to the signal conflict between the wireless switches in the same control environment, or it may cause the wireless switches in other control environments in the same building or other buildings to conduct long-distance to the surrounding. Signal collision caused by communication, so wireless co-frequency transmission of signals is not allowed in the prior art.

In the smart home industry, the so-called "close distance" usually refers to a communication distance of about 10 meters, such as the communication distance of wireless headphones, while "long distance" usually refers to a communication distance of about 50-100 meters.

Referring to Figures 2 to 4 of the present specification, a wireless control device according to a preferred embodiment of the present invention is explained in the accompanying description. The wireless control device transmits a wireless signal to a signal receiving end, including an operation module 1000, a control module 2000, a transmitter module 3000 and a power supply module 4000, wherein the operation module 1000 generates an operation according to an operation action instruction, the control module 2000 generates the corresponding code and control command according to the operation instruction generated by the operation module 1000 and controls the signal transmission time width 3001 of the wireless signal, wherein the transmission module 3000 controls according to the The control module 2000 transmits the control signal to the outside, the power supply module 4000 is electrically connected to the control module 2000 and the transmission module 3000, and the operation module 1000 triggers the power supply module 4000 to send the control module 2000 and the transmission module 3000 to the control module 2000. The transmitting module 3000 supplies power.

Preferably, the transmitting module 3000 uses a fixed specific frequency to transmit the wireless signal, the wireless control device has an ID, and the ID is recorded in the control module 2000, and the wireless signal contains the ID identification information, the signal transmission time width 3001 of the wireless signal is smaller than the action duration 1001 of the operation action, so as to use the same specific frequency to time-division transmission signals to make multiple said devices in the same control environment The wireless control devices are operated simultaneously and transmit the wireless signals without interfering with each other.

In detail, when actually producing the wireless control device, uniformly setting the wireless control device to the same specific frequency is convenient for production and can greatly improve production efficiency. By using the technology disclosed in the present invention, when there are two or more wireless control devices in the same control environment, since they all use the same specific frequency to transmit wireless signals, it is possible to easily achieve the same frequency and time-division wireless transmission. signal to reduce the bandwidth occupied by wireless signals.

It can be understood that, in the present invention, the signal transmission time width 3001 is the duration for which the transmission module 3000 transmits the wireless signal once.

It can be understood that transmitting the wireless signal once means that the control purpose can be accomplished by using the wireless signal once. In some embodiments, the same wireless signal may also be repeatedly transmitted multiple times. One wireless signal can achieve the control purpose.

It can be understood that, in the present invention, the action duration 1001 refers to the time from when the operation module 1000 moves under the action of a force and triggers the power supply module 4000 to generate electric energy until the operation module 1000 stops moving. In other words, the action duration 1001 refers to the time required by the operator to operate the wireless control device once by hand. In the present invention, the action duration is greater than or equal to 0.1 seconds and less than or equal to 0.5 seconds.

It can be understood that the "simultaneous" in the present invention refers to simultaneous operations on a macroscopic level, while on a microscopic level, there is an action time difference of at least 0.1 second between the actual transmission time of the signal.

In detail, as shown in Figures 3 and 4, when the human hand presses the switch, the fastest time to complete an operation is about 0.1 seconds, that is, 100 milliseconds. If a signal transmission task is completed within a time, for example, a communication is completed within 10 milliseconds, then when two or more of the wireless control devices are pressed at the same time, it is assumed that the two wireless control devices are operated simultaneously at the fastest speed. When the control device works, within a time difference of 100 milliseconds, due to the time difference between the operation duration 1001 of each wireless control device, the signal transmission time width 3001 of each wireless signal is smaller than the corresponding operation duration 1001 , that is, the transmission of each of the wireless signals is completed within the action duration, so the wireless signals generated by the two wireless control devices will not overlap. In other words, during the first operation duration 1001a of the first wireless control device, the first wireless signal is transmitted, and during the second operation duration 1001b of the second wireless control device, the transmission The second wireless signal, but because the first wireless signal and the second wireless signal exist for a very short time, although macroscopically, the first wireless control device and the second wireless control device operate simultaneously , but there is a time interval between the time when the two operate, that is, the action duration 1001, as long as the first signal transmission time width 3001a of the first wireless signal is smaller than the first action duration 1001a of the first wireless control device, The second signal transmission time width 3001b of the second wireless signal is smaller than the second operation duration 1001b of the second wireless control device, then the probability that the first wireless signal and the second wireless signal are simultaneously generated and transmitted It will be extremely low. Although the wireless control devices are operated at the same time on a macro level, since the signals are generated and transmitted by time division on a micro level, they will not interfere with each other.

It can be understood that, in the present invention, operating the wireless control device refers to performing a manipulation action on the corresponding wireless control device to activate the wireless control device, and the operation action includes but is not limited to pressing or in other ways. A manipulation action is performed on the wireless control device to actuate it.

It can be understood that, in order to distinguish and describe each of the wireless signals, in the present invention, names such as "the first wireless signal" and "the second wireless signal" are specially used, but in practical applications, there is no first and second wireless signals. Divide by two, or the restriction of which signal must be in front or which signal must be behind; in particular, the "first" and "second" refer to when two of the wireless control devices are actuated at the same time , according to the design of the present invention, microscopically, a plurality of the wireless control devices will transmit signals at different times successively.

Preferably, the time interval Δt between the first signal transmission time width 3001a of the first wireless control device and the second signal transmission time width 3001b of the second wireless control device is greater than or equal to 20 μs.

Therefore, even if the signals are transmitted on the same frequency, as long as there is a time difference, that is, the signals can be transmitted in time division, and there will be no mutual interference between the two signals. This principle is similar to the "zipper passage" of car driving. As long as each car enters the same lane in a staggered manner, each car can smoothly drive into the same lane without blocking. In other words, if the time to transmit the signal is less than 0.1 second, there will be no signal collision when the user operates the wireless switch to transmit the signal, that is, although the two control signals have the same frequency, they will not be transmitted simultaneously.

In more detail, if the period in which the wireless control device transmits wireless signals is further shortened, for example, the wireless control device completes one wireless signal transmission within 5 milliseconds, then in the time difference of 100 milliseconds, if There are 10 wireless control devices being operated. According to the above principle, there will be no conflict between these 10 wireless signals, that is, they will not affect each other.

It is understandable that in real life, when the user presses the switch on the wall with his hand, he does not press it at the fastest speed every time. Normally, the entire operation lasts for about 0.5 minutes from pressing to releasing. seconds, that is, 500 milliseconds, so you can use the 500 milliseconds to make as many wireless switches as possible to complete a control task individually.

Preferably, the control radius of the wireless control device is not more than 20 meters, so as to reduce the probability of mutual interference between multiple wireless control devices simultaneously transmitting wireless signals in the same control environment.

It can be understood that if a wireless switch is allowed to complete a communication within 10 milliseconds, then in a time period of 500 milliseconds, 500/10=50 switches can be theoretically allowed to be operated at the same time. Within a radius of 20-50 meters, the probability of more than 10 wireless switches being operated at the same time is almost non-existent. If the time for each of the wireless control devices to transmit the wireless signal is further shortened, for example, to 2 milliseconds, then in a daily home environment, when the wireless control device is manually operated to transmit the wireless signal, in one operation The process is 500 milliseconds. In theory, 500/2*0.2=50 of the wireless control devices can be operated simultaneously without signal collision, where 0.2 is the tolerance rate.

Preferably, the signal transmission time width 3001 is less than 2 milliseconds.

It can be understood that in the smart furniture system, according to the needs of various home and office places, within a range of 150 square meters, usually only less than 20 wireless control devices need to be set, so each wireless control device needs to be set. The signal transmission time width 3001 for the device to transmit the wireless signal once is set to be less than 2 milliseconds, so that there is basically no collision when transmitting wireless signals of the same frequency in space.

Preferably, the radiation power of the wireless signal transmitted by the transmitting module 3000 is greater than or equal to 0 dBm (ie, 1 mW) and less than or equal to 15 dBm, so as to save the energy loss of the wireless control device, and also control the wireless signal. The radiation range can reduce the probability of collision of the wireless signals.

Preferably, the specific frequency is a frequency below 5GHZ to avoid control failure caused by signal attenuation.

It can be understood that, as shown in Figure 5, in the very high frequency band of 433MHZ, the reliable transmission radius of indoor wireless signals can be controlled between 5-20 meters. If 20 wireless control devices are deployed in home 1, As mentioned above, each of the wireless control devices in family 1 basically does not have signal conflicts in daily use, while other families, such as family 2 to family 5, are far away from family 1 because the distance exceeds the effective control range, That is, family 1 and stop 2-family 5 are not in the same control environment, and the signals of the wireless control devices in other families will not cover the control environment of family 1, so they will not affect each other.

Preferably, the wireless control module 2000 is paired and connected to the signal receiving end, and the signal receiving end stores the information of the ID identification of the wireless control module 2000 paired with it, so as to preliminarily screen by the ID identification It is determined whether response processing is required for the received wireless signal.

The information identified by the ID is not repeated. By burning the ID identifier in each of the wireless control devices, and using the method of pairing and connecting the wireless control module 2000 with the signal receiving end, tens of thousands of sets can be deployed in hundreds of houses in a residential area. The wireless control device does not generate erroneous control.

In detail, based on the above technical solutions of the present invention, the wireless control device of the present invention is deployed in any furniture place in the world, as long as there is a signal time difference, ID difference of the wireless signal, and the wireless control device and the signal The receiving end pairing uses three elements, then it can reliably transmit wireless signals at the same frequency, save spectrum resources, reduce manufacturing costs, and facilitate popular applications.

In more detail, the ID difference means that different IDs (Identity documents) are programmed into the control module 2000 in each of the wireless control devices. When each of the wireless control devices transmits the wireless signal When the signal is received, the signal receiving end can identify which signal of the wireless control device they are, thereby reducing identification errors. Each wireless control device is paired with the signal receiving end, that is, the ID of the wireless control device is stored in the signal receiving end used with it, which is called pairing, that is, the process of identifying and storing in advance to So that when a plurality of the wireless control devices transmit the wireless signal, the signal receiving end only responds to the paired wireless control devices, thereby realizing reliable control.

Preferably, the radiation power of the wireless signal transmitted by the transmitting module is greater than or equal to 0 dBm (ie, 1 mW) and less than or equal to 15 dBm, the specific frequency is a frequency below 5 GHz, and the signal transmission time width 3001 is less than 2 milliseconds, so The wireless control module is paired and connected with the signal receiving end, and the signal receiving end stores the information of the ID mark of the wireless control module paired with it, so as to preliminarily screen and determine the received data through the ID mark. Whether the wireless signal requires response processing.

Referring to FIGS. 6 to 10C of the accompanying drawings of the present specification, according to a preferred embodiment of the present invention, the power supply module 4000 further includes a power generating device, and the power generating device The act of operation triggers and generates and outputs electrical energy, the power generation device with the drive device 100A being clarified in the following description. The power generating device further includes at least one coil 200A, wherein the coil 200A is disposed on the driving device 100A, and the coil 200A is driven by the driving device 100A to generate induced electrical energy.

It can be understood that, in the present invention, the driving device 100A drives the coil 200A to generate induced electrical energy, which means that the movement of the driving device 100A changes the magnetic flux around the coil 200A, thereby causing the coil 200A to generate induction. To generate electricity, the coil 200A may be moving or stationary during this process, which is not limited in the present invention.

In detail, the driving device 100A includes a driving bracket 10A, an accumulator 20A, a brake 30A and at least one magnetic attraction device 40A, wherein the brake 30A is attracted to the magnetic attraction device 40A, and the brake 30A conducts the magnetic force of the magnetic attraction device 40A. It is worth mentioning that the power generating device further includes a casing, wherein the driving device 100A is disposed in the casing. The brake 30A is fixedly arranged on the housing, wherein the accumulator 20A is arranged on the driving bracket 10A, and the driving bracket 10A has a movable fulcrum, when the driving bracket 10A is subjected to a sufficient amount of When the driving force is applied, the driving bracket 10A rotates around the movable fulcrum. The coil 200A is disposed on the brake 30A. When the driving bracket 10A rotates around the movable fulcrum, the coil 200A generates induced electric energy in the magnetic field generated by the magnetic attraction device 40A.

It is worth mentioning that the accumulator 20A includes a fixed end 21A and an energy storage end 22A extending outward from the fixed end 21A, wherein the fixed end 21A is fixed to the driving bracket 10A, so the The energy storage end 22A extends outward from the fixed end 21A. When the energy storage end 22A of the energy storage device 20A is subjected to force, the energy storage end 22A bends and deforms, and stores elastic potential energy. It can be understood that, the accumulator 20A may be, but not limited to, a metal dome, a plastic dome, or form an integral structure with the drive bracket 10A by means of plastic sealing.

In this preferred embodiment of the present invention, the magnetic attraction device 40A is fixed to the drive bracket 10A, and the magnetic attraction device 40A can rotate synchronously with the drive bracket 10A. The driving bracket 10A includes at least one pivoting end 11A and a driving end 12A extending from the pivoting end 11A, wherein the movable fulcrum is located at the pivoting end 11A of the driving bracket 10A, and the magnetic attraction The device 40A is fixedly arranged on the drive end 12A of the drive bracket 10A. It is worth mentioning that in the initial state, the magnetic attraction device 40A and the brake 30A are attracted to each other. When the driving bracket 10A is subjected to a sufficiently large driving force, the driving force and the magnetic attraction device The magnetic attraction force provided by 40A is reversed, and the driving bracket 10A drives the magnetic attraction device 40A to separate from the braking device 30A, that is, the driving bracket 10A drives the magnetic attraction device 40A to rotate, and changes the magnetic attraction device 40A. The magnetic field direction of the magnetic attraction device 40A causes the coil 200A located in the brake 30A to generate induced electrical energy.

It is worth mentioning that, in this preferred embodiment of the present invention, the specific shape and implementation of the driving bracket 10A are not limited herein. As an example, the driving bracket 10A may be, but not limited to, U-shaped, Y-shaped, I-shaped, T-shaped, mouth-shaped, π-shaped and other structures.

The magnetic attraction device 40A is fixedly disposed on the driving end 12A of the driving bracket 10A, wherein the driving end 12A of the driving bracket 10A can rotate around the movable fulcrum of the driving bracket 10A when the force is applied. It is worth mentioning that, in this preferred embodiment of the present invention, the brake 30A may be, but not limited to, metals or alloys with magnetic conduction. As an example, in this preferred embodiment of the present invention, the brake 30A is a magnetically conductive metal material or an alloy material. The coil 200A is wound around the brake 30A.

The magnetic attraction device 40A further includes at least one magnetic attraction unit 41A and at least one driving unit 42A, wherein the driving unit 42A is a material with magnetic permeability, and the driving unit 42A is disposed on the magnetic attraction unit 41A. In an initial state, the drive unit 42A is attracted to the brake 30A through the magnetic attraction unit 41A. The driving unit 42A can be, but not limited to, iron, cobalt, nickel, and other metals, alloys, or magnets, magnets, and the like that have a magnetic conduction effect.

The drive unit 42A includes a drive fixed end 421A and a drive extension end 422A integrally extending outward from the drive fixed end 421A, wherein the drive fixed end 421A of the drive unit 42A is fixed to the magnetic attraction Unit 41A, the drive extension end 422A protrudes toward the stopper 30A, wherein the drive extension end 422A partially overlaps the stopper 30A, so that the drive unit 42A and the stopper 30A are in the initial state adsorb each other. It can be understood that the brake 30A can also prevent the driving unit 42A from moving, so as to prevent the driving unit 42A from being displaced.

The magnetic attraction unit 41A may be, but not limited to, a magnet, a magnet, and other elements having a magnetic effect.

Preferably, in this preferred embodiment of the present invention, the rotation angle of the drive bracket 10A based on the movable fulcrum is less than or equal to 45 degrees. In other words, the rotation of the driving end 12A of the driving bracket 10A around the pivoting end 11A swings at an angle less than 45 degrees.

In particular, in this embodiment, the driving bracket 10A is pivoted, and in some embodiments, the driving bracket 10A can also be configured to move vertically up and down, regardless of the driving bracket 10A This kind of movement mode, as long as it can achieve the effect of separation from the brake 30A or labor-saving reset, it belongs to the protection scope of the present invention.

Different from the above first preferred embodiment, when the drive bracket 10A swings around the fulcrum, the drive unit 42A and the magnetic attraction unit 41A move synchronously, and the drive unit 42A will disengage from the brake 30A adsorption.

It is worth mentioning that the accumulator 20A is disposed on the driving end 12A of the driving bracket 10A, and elastic potential energy is stored by the accumulator 20A. When the elastic potential energy stored by the accumulator is sufficient to overcome When the force between the magnetic attraction device 40A and the brake 30A is applied, the accumulator 20A releases elastic potential energy to drive the drive bracket to swing at a high speed.

In particular, according to actual needs, in some embodiments, the accumulator 20A can also be disposed on the brake 30A, and at this time, the drive bracket 10A and the brake 30A move relative to each other to generate electrical energy. When the accumulator 20A is disposed on the brake 30A, the driving bracket 10A can be fixed, and the energy accumulator 20A is operated to drive the brake 30A and the driving bracket 10A to move relative to each other to generate electrical energy.

In a normal state, the magnetic attraction device 40A located at the driving end 12A is attracted to one end of the brake 30A under the action of magnetic force, and the driving end 12A is attracted and locked by the brake. The drive bracket 10A is in a magnetically locked state and cannot swing freely. In this state, the magnetic field of the magnetic attraction device 40A is stably conducted to the brake 30A through the driving unit 42A, and the magnetic field is stable, so no electrical energy is induced in the coil at this time.

When an external force drives the energy input end of the accumulator 20A, since the drive end 12A is adsorbed by the brake in advance, the accumulator 20A cannot immediately drive the drive bracket 10A to swing, and the accumulator 20A cannot immediately drive the drive bracket 10A to swing. 20A begins to deform under the push of external force, and gradually stores elastic potential energy. The accumulator 20A continues to bend, and the elastic potential energy becomes larger and larger. When the elastic potential energy stored by the accumulator 20A exceeds the magnetic attraction force of the brake 30A to attract the magnetic attraction device 40A, the drive The bracket 10A rotates around the movable fulcrum, so that the driving end 12A and the brake 30A are separated from each other. When separated, the driving unit 42A and the brake 30A move in opposite directions. The driving end 12A and the brake 30A are far away from each other, rather than colliding in the same direction. Therefore, the separation process will not produce a "slap" impact sound, thus playing a significant role in reducing noise.

It should be particularly pointed out that when the driving end 12A is separated from the brake 30A, the coil 200A will also generate instantaneous electric energy. Because, in the normal state, the driving end 12A and the brake 30A are attracted by the magnetic force of the magnetic attraction device 40A, and the magnetic field stably passes through the brake 30; and when the driving end 12A and the brake 30A At the moment of separation, the magnetic field density in the brake 30 has undergone a huge change, resulting in a changing magnetic field, and the magnetic energy density is instantly reduced by 80% from the saturation state, or even more, due to the density of the magnetic field lines. The change results in the disturbance of the magnetic field, which causes the coils sleeved on the outer periphery of the brake 30 to generate induced electrical energy.

In particular, the relative time of separation of the drive end 12A from the brake is less than 100 milliseconds to generate higher induced energy in the coil. Preferably, the separation stroke of the magnetic attraction device 40A from the brake 30A is less than (including) 3 mm, so that after the magnetic attraction device 40A is separated from the brake 30A for a certain distance, under the action of a magnetic field, when the When the external force is removed, the magnetic attraction device 40A can still automatically return to its position under the action of the magnetic field, and the drive unit 42A and the brake 30A return to the adsorption state from the separated state, that is, return to the normal state.

After the magnetic attraction device 40A is separated from the brake 30A for a certain distance, the two are still in the range of the magnetic field. When the external force or driving force disappears, the driving unit 42A and the brake 30A will be automatically adsorbed together again under the use of the magnetic field. Since the process of automatically adsorbing together again does not have the elastic acceleration impact of the accumulator, therefore The process of engaging the driving part with the brake 30A is relatively quiet, so as to achieve the design purpose that the noise generated by the power generating device during the reset operation is also very small.

It should be particularly pointed out that the present invention discloses an automatic resettable labor-saving power generating device, wherein the magnetic field provided by the magnet not only plays the role of generating electricity, but also plays the role of automatically reseting the power generating device, reducing the existing The number of technical components and the difficulty of mechanical design have extremely high market value.

Of particular importance, as previously mentioned, the travel of the drive bracket 10A to separate from the brake 30A is less than (including) 3 mm. Preferably, when the separation distance is less than 0.3 mm, the strength and effect of the automatic reset by using the magnetic force are relatively good. In the separation stroke of 0.3 mm, the energy of about 150 uJ can be generated in the generator coil, which is enough to drive a radio frequency circuit to transmit 15 bytes of control data with a radio frequency power of 6 dB. Because if the distance between the driving end 12A and the brake 30A is relatively far, due to the significant decrease in the magnetic force, the magnetic force of the magnetic force reset will be weakened, and the reset speed will be slowed down. At this time, a smaller The strength of the spring to help the generator reset semi-automatically.

In other words, in this preferred embodiment of the present invention, the driving device further includes an auxiliary spring, wherein the auxiliary spring is provided at the driving end 12A of the driving bracket 10A, and the driving bracket 10A is When the magnetic attraction device 40A is driven to separate from the brake 30A, a restoring force is exerted by the auxiliary spring to accelerate the return of the driving bracket 10A in time.

It is worth mentioning that the spring for assisting return is substantially different from the return spring in the prior art, because the thrust of the spring in the prior art is greater than the driving force of the generator, which is a laborious device; The thrust of the spring is much smaller than the force required by the generator to drive, and it is a labor-saving component; as mentioned above, in the prior art, if the driving force required by the generator when resetting is 3N, then only 60% or more is required in the present invention. It can be driven with a lower driving force, which significantly reduces the pressing force and realizes the effect of labor saving.

Therefore, a significant feature of the present invention is that the force required for the reset operation of the power generating device is much smaller than the force required for the pressing operation, or in other words, when the power generating device is in a labor-saving driving state, the reset operation force is less than 1/2 of the pressing force. .

After the brake 30A is separated from the driving end 12A, the magnetic attraction between the brake 30 and the driving unit 42A is still in the range. When the input mechanical force is released, the brake 30A and the driving unit 42A automatically or passively return to the normal state under the action of the magnetic attraction, thereby reducing the driving force during the reset operation. It is worth mentioning that, in the above description, passive means that when the drive unit 42A is separated from the brake 30A too far, the magnetic force alone is not enough to complete the reset operation. Auxiliary devices (or auxiliary springs) are used to assist to complete the reset, so it is called "passive" reset. Although the passive reset has a spring, the force of the spring to reset is very small. Compared with the prior art, the force of the spring is much smaller than the force of driving the generator. That is, in the present invention, the force of the spring is assisted by the magnetic force to reset, and the force of the spring is smaller than the force required to drive the generator to generate electricity. Therefore, the restoring force is significantly reduced, which has the beneficial effect of labor saving.

It can be understood that the power generating device may be an electromagnetic generator or a piezoelectric ceramic generator or other generators in the form of converting mechanical energy into electrical energy.
