Description

Technical Field

[0001] This invention relates to the field of power generation devices, and in particular to a manual power generation module and self-powered device for single-press triggering. Background Technology

[0002] A push-button power generation module is a miniature energy harvesting device that converts mechanical energy into electrical energy. It is widely used in wireless switches, self-powered doorbells, IoT sensor nodes, and portable emergency electronic devices. Its typical working principle includes electromagnetic induction, piezoelectric effect, or electrostatic harvesting: the operator presses a button to drive the rotor to cut magnetic field lines or deform the piezoelectric material, thereby generating pulsed electrical energy to power downstream loads (such as RF transmitter modules and LED indicator lights) momentarily.

[0003] To improve power generation efficiency, existing designs often increase the rotor's speed and displacement by increasing spring stiffness and extending the reset stroke. However, this directly leads to a significant increase in button resistance. Furthermore, due to factors such as the gravity of moving parts, the operating feel and power generation performance of this type of vertical motion structure change under different installation orientations (such as horizontal and vertical installation). Operators need to apply different operating forces multiple times to drive the rotor, resulting in a decreased user experience. Moreover, due to the varying operating force, the electrical energy generated by the power generation device fluctuates each time, reducing the user acceptance of high-end smart home and consumer electronics products. Summary of the Invention

[0004] The purpose of this invention is to provide a manual power generation module and self-powered device for single-press triggering, so as to solve the problems existing in the prior art, improve the operator's operating feel, and ensure the stability of the power output of the power generation device.

[0005] To achieve the above objectives, the present invention provides the following solution: The present invention provides a manual power generation module for single-press triggering, comprising: a swing assembly rotatably mounted on a base and a magnetic circuit assembly fixedly mounted on the base, the swing assembly including a balance wheel, the balance wheel having at least one permanent magnet, and the magnetic circuit assembly and the permanent magnet forming a variable magnetic circuit; It also includes a reset element for driving the balance wheel to oscillate periodically and for resetting the balance wheel; the balance wheel is provided with a balancing assembly for keeping the balance wheel in a balanced position.

[0006] In one embodiment, the reset element includes a hairspring, the inner end of which is connected to the base, and the outer end of which is connected to the balance wheel.

[0007] In one embodiment, the balancing assembly includes at least a counterweight, and the equivalent center of gravity of the counterweight, permanent magnet, and balance wheel is located at or through the oscillation axis of the oscillation assembly.

[0008] In one embodiment, the magnetic circuit assembly includes a magnetic conductor and an induction coil wound on the magnetic conductor. The magnetic conductor is a ring structure with a notch, and at least one permanent magnet is symmetrically arranged about the magnetic conductor.

[0009] In one embodiment, the balance wheel includes a first half-wheel and a second half-wheel arranged symmetrically, a permanent magnet and a counterweight are respectively disposed on the first half-wheel and the second half-wheel, and the symmetry plane of the first half-wheel and the second half-wheel is perpendicular to the symmetry plane of the magnetic conductor.

[0010] In one embodiment, six permanent magnets are provided, which are disposed on the first half-wheel and arranged symmetrically with respect to the magnetic conductor.

[0011] In one embodiment, the oscillating assembly further includes a drive gear fixed coaxially with the balance wheel, and the drive gear is connected to the transmission mechanism for transmission.

[0012] In one embodiment, a limiting element is also included, comprising a limiting pin for limiting the maximum swing angle of the balance wheel.

[0013] A self-powered device includes the aforementioned manual power generation module and an energy management circuit electrically connected to its power output terminal.

[0014] In one embodiment, the energy management circuit includes an energy storage unit for storing electrical energy and a load circuit for supplying power to the working end.

[0015] The present invention achieves the following technical effects compared to the prior art: The magnetic circuit assembly and the oscillating assembly are coaxially arranged. The oscillating assembly is rotatably mounted on the base and includes a balance wheel with at least one permanent magnet. The permanent magnet oscillates synchronously with the oscillation. The magnetic circuit assembly is fixedly mounted on the base. The permanent magnet on the oscillating assembly and the magnetic circuit assembly form a variable magnetic circuit. When the reset element drives the balance wheel to oscillate, it generates an induced electromotive force on the magnetic circuit assembly. The balance wheel is also equipped with a balancing assembly. The balancing assembly precisely configures the rotational inertia and center of gravity of the oscillating assembly, making it form a stable resonant system with the reset element. This ensures that the balance wheel performs simple harmonic vibration with a fixed frequency and decay law after each press, guaranteeing the stability of the output power. At the same time, the balancing assembly balances the gravity distribution on the balance wheel, adjusting the "equivalent center of gravity" of the balance wheel to coincide with the axis of rotation. At this time, when the balance wheel oscillates, the operating force applied by the operator and the balance wheel reset process are only used to overcome the friction between the components, thereby ensuring that the operating force felt by the operator remains basically unchanged under different spatial postures, improving the operator's operating feel.

Detailed Implementation

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] The purpose of this invention is to provide a manual power generation module and self-powered device for single-press triggering, so as to solve the problems existing in the prior art, improve the operator's operating feel, and ensure the stability of the power output of the power generation device.

[0020] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0021] like Figures 1 to 6 As shown, this embodiment provides a manual power generation module for single-press triggering, including a magnetic circuit assembly 3 and a swing assembly 1. The magnetic circuit assembly 3 includes a magnetic conductor 31, which is generally ring-shaped with a notch at any position on the ring structure. Except for the notch, an induction coil 32 is wound around the remaining positions of the magnetic conductor 31. The magnetic conductor 31 with the induction coil 32 wound around it is fixedly mounted on a base 7. The swing assembly 1 includes a balance wheel 11, which is coaxially arranged with the magnetic conductor 31 and rotatably mounted on the base 7. At least one permanent magnet is disposed on the balance wheel 11. The permanent magnets are symmetrically arranged about the magnetic conductor 31, meaning they are in a balanced position when symmetrically distributed about the magnetic conductor 31. The power generation module also includes a reset mechanism. Component 4, the reset component 4, is used to drive the balance wheel 11 to oscillate periodically when the balance wheel 11 starts to oscillate. At this time, the positional relationship between the permanent magnet and the notch on the magnetic conductor 31 is: close to the notch on the magnetic conductor 31 → covering the notch on the magnetic conductor 31 → away from the notch on the magnetic conductor 31 → close to the notch on the magnetic conductor 31. The permanent magnet and the induction coil 32 form a variable magnetic circuit. The permanent magnet moves back and forth according to the above process, thereby generating an induced electromotive force on the induction coil 32. The balance wheel 11 is also equipped with a balancing component. The rotational inertia and center of gravity of the oscillation component 1 are precisely configured by the balancing component, so that it forms a stable resonance system with the reset component 4, ensuring that the balance wheel 11 performs simple harmonic oscillation with a fixed frequency and decay law after each press, thus ensuring the stability of the output power. Meanwhile, as a miniature energy harvesting device, the push-button power generation module is widely used in wireless switches, self-powered doorbells, IoT sensor nodes, and portable emergency electronic devices. Its installation posture is affected by its location, such as a vertical orientation or an angled orientation relative to the horizontal. In this case, the permanent magnets on the balance wheel 11 often deviate from their equilibrium position under the influence of gravity. That is, the permanent magnets will no longer be symmetrically distributed about the magnetic conductor 31. When the operator applies operating force, they not only need to overcome the friction between the components in the power generation module but also the additional torque generated on the reset element 4 due to the permanent magnets deviating from their equilibrium position. This results in different postures of the operator within the power generation module. The applied operating force can produce significant differences; however, the balancing component can balance the gravity distribution on the balance wheel 11, adjusting the "equivalent center of gravity" of the balance wheel 11 to coincide with the axis of rotation, ensuring that the permanent magnet is in a balanced position in the initial state under any posture of the power generation module. At this time, when the balance wheel 11 is driven to rotate by the operating force, the operating force and the reset process of the balance wheel 11 are only determined by the friction between the reset element 4 and each component. That is, the operating force applied by the operator is only used to overcome the friction between each component and the resistance generated by the reset element 4, and no additional torque is generated. This ensures that the operating force felt by the operator remains basically unchanged under different spatial postures, improving the operator's operating feel.

[0022] In this embodiment, the reset element 4 includes a hairspring. The inner end of the hairspring is connected to the base 7, and the outer end of the hairspring is connected to the balance wheel 11. When the power generation module is not generating electricity, the hairspring is in a released state, neither compressed nor stretched. When power generation is required, the balance wheel 11 is driven to swing by an operating force, and the hairspring is compressed, giving it elastic potential energy to store energy for the subsequent periodic swing of the balance wheel 11. After releasing the operating force, the hairspring releases its elastic potential energy, thereby driving the balance wheel 11 to swing periodically. In the vertical or tilted state, if the permanent magnet deviates from its equilibrium position, the hairspring will be compressed or stretched. At this time, the operating force needs to overcome the additional torque generated by the deformation of the hairspring. The function of the balancing component is to maintain the permanent magnet in a balanced position when the power generation module is not generating electricity, thereby avoiding additional deformation of the hairspring before the operating force is applied, and ensuring the consistency of the operating force applied by the operator in any posture of the power generation module.

[0023] The balancing assembly includes at least a counterweight. The counterweight is positioned on the side of the balance wheel 11 that is symmetrical to the magnetic conductor 31. The position of the counterweight on the balance wheel 11 is also symmetrical about the symmetrical surface of the magnetic conductor 31. It is used to adjust the center of gravity on the balance wheel 11 so that the equivalent center of gravity of the counterweight, the permanent magnet and the balance wheel 11 is located at or passes through the pivot, thus preventing the counterweight from causing additional deformation of the hairspring when it is not generating electricity.

[0024] Preferably, the counterweight includes a first counterweight 12 and a second counterweight 13, which are symmetrically arranged about the magnetic conductor 31.

[0025] The balance wheel 11 includes a first half-wheel and a second half-wheel, which are integrally designed. The centers of the first and second half-wheels coincide and are connected to the axis of rotation through their centers. The planes of symmetry of the first and second half-wheels are perpendicular to the plane of symmetry of the magnetic conductor 31. Driven by the axis of rotation, the first and second half-wheels rotate synchronously. A permanent magnet is mounted on the first half-wheel, and a counterweight is mounted on the second half-wheel. The first and second half-wheels are symmetrical about the axis of rotation, ensuring a uniform mass distribution of the balance wheel 11. This facilitates the adjustment of the equivalent center of gravity of the counterweight, permanent magnet, and balance wheel 11 after mounting the permanent magnet on the balance wheel 11.

[0026] The number of permanent magnets is not limited and can be adjusted according to the power generation requirements of the power generation module's operating environment. However, it is necessary to ensure that the permanent magnets are symmetrically distributed on the first half-wheel about the symmetrical plane of the magnetic conductor 31. If the number of permanent magnets is odd, any one permanent magnet is placed in the area on the first half-wheel corresponding to the symmetrical plane of the magnetic conductor 31, and then the remaining permanent magnets are symmetrically placed in the areas on both sides of the symmetrical plane of the magnetic conductor 31 on the first half-wheel. If the number of permanent magnets is even, the number of permanent magnets placed in the areas on both sides of the symmetrical plane of the magnetic conductor 31 on the first half-wheel is equal. In this embodiment, six permanent magnets are provided. Figure 6 Three permanent magnets are respectively arranged on both sides of the symmetrical plane of the magnetic conductor 31. The six permanent magnets are arranged in a clockwise direction as the first magnetic source 310, the second magnetic source 311, the third magnetic source 312, the fourth magnetic source 313, the fifth magnetic source 314 and the sixth magnetic source 315. In the figure, ①②③④⑤⑥ represent the first magnetic source 310, the second magnetic source 311, the third magnetic source 312, the fourth magnetic source 313, the fifth magnetic source 314 and the sixth magnetic source 315. The first magnetic source 310 and the sixth magnetic source 315 are symmetrical, the second magnetic source 311 and the fifth magnetic source 314 are symmetrical, and the third magnetic source 312 and the fourth magnetic source 313 are symmetrical.

[0027] Preferably, in order to match the arc-shaped edge of the first half-wheel, the permanent magnet is arc-shaped as a whole, and its curvature is the same as that of the first half-wheel.

[0028] To ensure that the induction coil 32 generates an induced electromotive force with maximum efficiency when the balance wheel 11 oscillates, the arc length of the permanent magnet is greater than the arc length of the notch on the magnetic conductor 31, ensuring that the magnetic conductor 31 completely covers the notch. Multiple permanent magnets are spaced apart, with an arc-shaped blank area between adjacent permanent magnets. The arc length of the blank area is greater than the arc length of the notch on the magnetic conductor 31, ensuring that the blank area also completely covers the notch on the magnetic conductor. When the permanent magnet on the first half of the wheel covers the notch on the magnetic conductor 31, the induction coil 32 has the maximum magnetic flux. When the blank area on the first half of the wheel covers the notch on the magnetic conductor 31, the magnetic flux in the induction coil 32 is close to zero. By changing the relative positions of the permanent magnets and the blank area with respect to the notch on the magnetic conductor 31, the magnetic flux in the induction coil 32 changes, thereby generating an induced electromotive force in the induction coil 32.

[0029] After the operating force is applied, the third magnetic source 312, the second magnetic source 311, and the first magnetic source 310 pass through the notch on the magnetic conductor 31 in sequence, and store energy for the hairspring through the operating force. After the operating force is released, the elastic potential energy stored in the hairspring is released. Under the action of the hairspring, the balance wheel 11 begins to swing. The third magnetic source 312, the second magnetic source 311, and the first magnetic source 310 pass through the notch on the magnetic conductor 31 in sequence, and an induced electromotive force is generated on the induction coil 32. Under the action of inertia, the fourth magnetic source 313, the fifth magnetic source 314, and the sixth magnetic source 315 also pass through the notch on the magnetic conductor 31 in sequence, and an induced electromotive force is continuously generated on the induction coil 32. When the sixth magnetic source 315 crosses the notch on the magnetic conductor 31, under the action of the inertia of the balance wheel 11, the hairspring stores energy again, and the hairspring drives the permanent magnet to pass through the notch on the magnetic conductor 31 in sequence again, so that a periodic induced electromotive force appears on the induction coil 32. As friction exists between the components in the power generation module, the elastic potential energy stored in the hairspring gradually decreases. Therefore, the balance wheel 11 gradually stops under the action of friction. After stopping, the blank area between the third magnetic source 312 and the fourth magnetic source 313 aligns with the notch of the magnetic conductor 31, ensuring that the magnetic conductor 31 is in a balanced position after the balance wheel 11 stops swinging.

[0030] The six permanent magnets on the first half of the wheel are arranged with adjacent magnetic poles in opposite directions. For example, if the left end of the first magnetic source 310 is the N pole and the right end is the S pole, then the left end of the second magnetic source 311 is the S pole and the right end is the N pole, the left end of the third magnetic source 312 is the N pole and the right end is the S pole, and so on for the fourth, fifth, and sixth magnetic sources 313 and 314. When this magnetic pole arrangement is used, the direction of the magnetic flux inside the magnetic conductor 31 will alternate when aligned with the notch on the magnetic conductor 31. Therefore, during the oscillation of the balance wheel 11, the magnetic flux passing through the induction coil 32 will increase from zero to its maximum value, then decrease to zero, then increase back to its maximum value, and then decrease to zero, forming an alternating positive and negative waveform. The ideal curve is shown below. Figure 9 As shown. This bidirectional waveform induced electromotive force can achieve higher energy utilization efficiency in subsequent rectifier circuits.

[0031] The six permanent magnets on the first half of the wheel can also be arranged with adjacent magnetic poles pointing in the same direction. For example, if the left end of the first magnetic source 310 is the N pole and the right end is the S pole, then the left end of the second magnetic source 311 is the N pole and the right end is the S pole, the left end of the third magnetic source 312 is the N pole and the right end is the S pole, and the distribution of the fourth magnetic source 313, the fifth magnetic source 314, and the sixth magnetic source 315 follows the same pattern. When this magnetic pole arrangement is used, during the oscillation of the balance wheel 11, the magnetic flux passing through the induction coil 32 will increase from zero to its maximum value, then decrease to zero, and continue to increase from zero to its maximum value, then decrease to zero. The magnetic flux changes continuously between zero and its maximum value, and the change in magnetic flux in the induction coil 32 presents a continuous waveform, the ideal curve of which is as follows: Figure 10 As shown.

[0032] The oscillating assembly 1 also includes a drive gear 14 fixed coaxially with the balance wheel 11. The drive gear 14 drives the rotating shaft to rotate synchronously. The drive gear 14 is connected to the transmission mechanism 2. The transmission mechanism 2 converts the operating force into the rotation of the drive gear 14, thereby driving the balance wheel 11 on the rotating shaft to oscillate within a preset range, thus realizing the energy storage of the hairspring spring.

[0033] refer to Figure 7 and Figure 8The transmission mechanism 2 includes a button 21 and a lever 25 for applying operating force. The power generation module is located inside the housing, and the button 21 is located on the outside of the housing. The button 21 is connected to a conical block 24 via a pressure rod 23. A disc spring 22 is provided between the button 21 and the outer side of the housing. The pressure rod 23 passes through the disc spring 22 and extends into the housing. The conical block 24 is located inside the housing, and the pressure rod 23 is connected to the bottom surface of the conical block 24, so that the top of the conical block 24 faces away from the button 21. The arc-shaped side of the conical block 24 abuts against the end of the lever 25. The lever 25 is rotatably connected to the inner wall of the housing via a hinge 26. When key 21 drives the conical block 24 to move, the side of the conical block 24 pushes the lever 25 to swing around the hinge 26. The end of the lever 25 is movably provided with a push rod 27, which extends to the pivot of the swing wheel 11. Under the action of the guide tube, the push rod 27 converts the swing of the lever 25 into the linear motion of the push rod 27. A rack 28 is provided on the end of the push rod 27 near the pivot. The rack 28 meshes with a gear on the pivot, which drives the pivot to rotate in the forward direction (it can be seen from the perspective of the figure that the forward rotation of the pivot is clockwise), thereby converting the operating force applied by the operator into elastic potential energy stored in the hairspring.

[0034] Since the power generation module relies on the periodic oscillation of the balance wheel 11 within a certain range to generate electricity, the rotation angle of the oscillation determines the amount of potential energy stored in the hairspring during the energy storage process through the operating force. Under normal conditions, the first half-wheel is located on one side of the notch on the magnetic conductor 31. To prevent the second half-wheel from rotating to the side of the notch on the magnetic conductor 31 during the oscillation of the balance wheel 11, a limit pin 5 is provided on the first balance wheel 11. In this embodiment, when storing energy in the hairspring through the operating force, the... Figure 1 In the initial position, the balance wheel 11 rotates clockwise. The base 7 blocks the limit pin 5, so that the balance wheel 11 can only rotate 90 degrees clockwise under the action of the operation force. After the button 21 is released, the swing amplitude of the balance wheel 11 is always less than 90 degrees under the action of friction, thereby preventing the first half wheel and the second half wheel from being swapped after the balance wheel 11 stops, and ensuring the normal use of the power generation module.

[0035] This embodiment also provides a self-powered device, including the above-mentioned manual power generation module. The power output terminal of the induction coil 32 in the power generation module is used to output electrical energy. The power output terminal is electrically connected to the energy management circuit 6 and provides electrical energy to the energy management circuit 6.

[0036] Taking a hospital's wireless pager as an example, the energy storage unit is an energy storage capacitor, and the load circuit is a low-power radio frequency (RF) transmitting circuit. When a call for medical staff is needed, pressing button 21 generates electrical energy. This energy is first rectified and converted from DC to DC by a semiconductor switch and the energy storage capacitor in the energy harvesting circuit, and then stored. This converts the DC voltage output by the induction coil 32 into the DC voltage required by the RF transmitting circuit and stores it in the energy storage capacitor. When the voltage of the energy storage capacitor reaches the minimum preset operating threshold V_min (in this embodiment, the minimum operating voltage of the RF transmitting circuit is 3.3V), the RF transmitting circuit is activated by the trigger circuit in the energy management circuit 6. The RF transmitting circuit reads the device ID and sends it to the receiving host located at the nurse station via a radio frequency signal.

[0037] In this embodiment, since the power generation module can generate ≥2.1mJ of electrical energy with a single press, which is sufficient to support the RF transmitting circuit to complete a data reading and transmission task, the entire wireless pager does not require any battery, achieving true maintenance-free and wireless operation.

[0038] Any adaptive changes made according to actual needs are within the scope of protection of this invention.
