Abstract
Description
Technical Field
[0001] This utility model relates to a device that can generate electricity by rotation. Background Technology
[0002] With the continuous development and popularization of the Internet of Things (IoT) in recent years, there is a need to monitor the status of different objects by adding sensors and transmitting corresponding status signals wirelessly, thereby achieving intelligent linkage and automated control. Sensors and wireless transmission require power to function, with batteries being a common method. However, batteries can run out of power, requiring regular maintenance and causing inconvenience. Considering that some objects require relatively simple control signals, and these objects usually perform corresponding actions when sending signals, such as opening and closing door locks, these actions can drive self-generating devices to generate electricity and trigger wireless signal transmission circuits to send signals. Existing common self-generating devices typically use coil windings with movable magnetic cores. The oscillation of the magnetic core contacts different magnetic bodies to change the magnetic flux of the coil windings and generate electricity. However, because the oscillation of the magnetic core is limited to within the coil windings, and the coil windings must be relatively close to the magnetic core to generate sufficient electricity to create a sufficient change in magnetic flux, this structure limits the oscillation range of the magnetic core, resulting in relatively low power generation and making it unsuitable for driving some power-intensive electronic devices. Utility Model Content
[0003] This utility model provides a device that uses rotation to drive a generator coil module or a magnetic body to generate electricity. The entire device can coordinate with the movement of the corresponding object to drive the generator coil module and the magnetic body to generate relative rotation, thereby realizing induction generation in the generator coil module to meet the power supply needs of electrical equipment.
[0004] A rotary self-generating device includes a generating coil module, a magnetic body, and a reciprocating rotating device; the rotating device is connected to a drive mechanism; one of the generating coil module and the magnetic body is mounted on the rotating device and rotates relative to the other under the drive of the rotating device, causing the two to move closer or separate, thereby changing the magnetic flux of the generating coil module accordingly; the output terminal of the generating coil module is connected to the electrical equipment.
[0005] The rotating device includes a rotating component and a fixed component. The rotating component is rotatably connected to the fixed component via a rotating shaft. The power generation coil module and the magnet are respectively mounted on the rotating component and the fixed component. The rotating component is connected to the driving mechanism.
[0006] The generator coil module is mounted on the rotating part, and the magnetic body consists of two sets, which are located on the outer edge of the rotating part corresponding to the position of the generator coil module.
[0007] The power generation coil module extends to the fixing member and is defined between the two magnetic bodies.
[0008] The power generation coil module includes a magnetic core and a coil winding wound on the magnetic core. The magnetic core extends to the fixing member and is defined between two magnetic bodies.
[0009] The rotating component is provided with a rotating block, which is rotatably connected to the rotating component via a rotating shaft. The rotating component is provided with two limiting blocks for limiting the rotation amplitude of the rotating block. The rotation of the rotating block is limited between the two limiting blocks. The rotating block is connected to the driving mechanism.
[0010] The rotating self-generating device is installed on the door and connected to the door's lock body. The driving mechanism is the lock tongue, lock cylinder, or locking bolt of the lock body. The rotating component is also equipped with a reset device. The driving mechanism pushes the rotating block to rotate and pushes the rotating component through a limit block to cause the generating coil module to separate from the magnetic body. The change in magnetic flux of the generating coil module causes the coil winding to generate electricity. As the generating coil module approaches another magnetic body, the magnetic flux of the generating coil module changes again, causing the coil winding to generate electricity. The driving mechanism resets, and the reset device drives the rotating block to rotate in the opposite direction and pushes the rotating component through another limit block to cause the generating coil module to separate from the magnetic body. The change in magnetic flux of the generating coil module causes the coil winding to generate electricity. As the generating coil module approaches another magnetic body, the magnetic flux of the generating coil module changes again, causing the coil winding to generate electricity.
[0011] The rotating self-generating device is mounted on a guide rail, which has a protrusion that abuts against the rotating block. The rotating component also has a reset device. The guide rail slides and the protrusion pushes the rotating block to rotate. Through a limiting block, the rotating component is pushed to separate the generating coil module from the magnetic body. The change in magnetic flux of the generating coil module causes the coil winding to generate electricity. As the generating coil module approaches another magnetic body, the magnetic flux of the generating coil module changes again, causing the coil winding to generate electricity. The drive mechanism resets, and the reset device drives the rotating block to rotate in the opposite direction. Through another limiting block, the rotating component is pushed to separate the generating coil module from the magnetic body. The change in magnetic flux of the generating coil module causes the coil winding to generate electricity. As the generating coil module approaches another magnetic body, the magnetic flux of the generating coil module changes again, causing the coil winding to generate electricity.
[0012] The rotary self-generating device is mounted on a device with a rotating shaft. The rotating shaft is connected to a rotating block and drives the rotating block to rotate. A limiting block pushes the rotating component to separate the generating coil module from the magnetic body. The change in magnetic flux of the generating coil module causes the coil winding to generate electricity. As the generating coil module approaches another magnetic body, the magnetic flux of the generating coil module changes again, causing the coil winding to generate electricity. The rotating shaft rotates in the opposite direction, driving the rotating block to rotate in the opposite direction. Another limiting block pushes the rotating component to separate the generating coil module from the magnetic body. The change in magnetic flux of the generating coil module causes the coil winding to generate electricity. As the generating coil module approaches another magnetic body, the magnetic flux of the generating coil module changes again, causing the coil winding to generate electricity.
[0013] The rotating shaft is a hinged rotating shaft, and the rotating shaft is connected to the rotating block through a gear transmission device.
[0014] The rotating shaft is the rotating shaft of a rotary switch.
[0015] The rotating shaft is connected to a push-button switch, and the push-button switch and the rotating shaft are connected by a meshing rack and gear.
[0016] The rotating shaft is connected to the foot pedal device.
[0017] The beneficial effects of this invention are as follows: The driving mechanism causes the generator coil module and the magnetic body to rotate relative to each other, thereby generating electricity by changing the magnetic flux in the coil windings of the generator coil module. Since the generator coil module and the magnetic body are relatively separated in this invention, compared to existing oscillating structures using a magnetic core, this invention can adjust their relative positions according to the movement of the object to match its motion and achieve self-generation, generating sufficient electricity to meet the power supply needs of different electrical devices.

The term "and / or" as used herein includes any combination of one or more of the associated listed items.
[0033] It should be understood that although the terms first, second, third, etc., may be used in this disclosure to describe various elements, these elements should not be limited to these terms. These terms are only used to distinguish elements of the same type from one another. For example, without departing from the scope of this disclosure, a first element may also be referred to as a second element, and similarly, a second element may also be referred to as a first element.
[0034] like Figure 1 As shown, the rotary self-generating device includes a generating coil module 1, a magnetic body 2, and a reciprocating rotating device 3. The rotating device 3 is connected to a drive mechanism, which is a motion-corresponding component generated during the movement of the related object. Detailed descriptions of different embodiments will follow.
[0035] One of the power generation coil module 1 and the magnetic body 2 is mounted on the rotating device 3, while the other can be mounted in a relatively fixed position. As the two are gradually rotated by the rotating device 3 to a position where they are in contact, the coil module in the power generation coil module 1 cuts the magnetic lines of force of the magnetic body 2, generating induced electricity. Similarly, when the rotating device 3 rotates in the opposite direction to separate the two, the coil module moves in the opposite direction to cut the magnetic lines of force of the magnetic body 2, generating induced electricity. The induced electricity generated by the power generation coil module 1 is connected to the electrical equipment via the output terminal.
[0036] To facilitate the integrated manufacturing of the rotary self-generating device of this utility model, the rotating device 3 includes a rotating component 31 and a fixed component 32, wherein the rotating component 31 is rotatably connected to the fixed component 32 via a rotating shaft. The generating coil module 1 and the magnetic body 2 are respectively mounted on the rotating component 31 and the fixed component 32, and then the rotating component 31 is driven to rotate by a driving mechanism.
[0037] Specifically, the magnetic body 2 can be mounted on the rotating part 31, and the corresponding power generation coil module 1 can be mounted on the fixed part 32. The same effect can be achieved by mounting the power generation coil module 1 on the rotating part 31. However, the preferred embodiment of this invention is to mount the power generation coil module 1 on the rotating part 31, specifically to increase the power generation of the self-generating device. The coil winding 12 of the power generation coil module 1 typically requires a large number of turns, therefore the rotating part 31 has sufficient space for mounting and fixing the coil winding 12. Simultaneously, a corresponding number of magnetic bodies 2, such as two sets, can be mounted on the fixed part 32 as needed. When the power generation coil module 1 approaches different magnetic bodies 2, it can generate electricity, thereby transmitting the different positional states of the object through corresponding reactive power generation signals.
[0038] The utility model proposes two structures for the power generation coil module 1 to meet different application needs. For example... Figure 1As shown, the power generation coil module 1 is mounted entirely on the edge of the rotating component 31, and the magnetic bodies 2 are arranged on both sides of the power generation coil module 1 at a set interval. When the rotating component 31 moves the power generation coil module 1 closer to or away from the two different magnetic bodies 2, induction power generation is generated. Another embodiment is as follows: Figure 2 As shown, the rotating component 31 is composed of the magnetic core 11 of the power generation coil module 1. The coil winding 12 is wound in the magnetic core 11. Part of the magnetic core 11 extends to the fixing component 32. The magnetic body 2 is arranged on both sides of the magnetic core 11 that extends to the fixing point according to the set spacing. By contacting or separating the extended magnetic core 11 from the magnetic body 2, the changing magnetic flux is guided to the coil winding 12 through the magnetic core 11, thereby generating induction power.
[0039] To adapt the rotation angle of the rotating component 31 to the travel of different objects, a rotating block 33 is provided on the rotating component 31. The rotating block 33 is rotatably connected to the rotating component 31 via a rotating shaft. The rotating component 31 is provided with two limiting blocks 34 to limit the rotation amplitude of the rotating block 33. The rotation of the rotating block 33 is limited between the two limiting blocks 34. The rotating block 33 is connected to the drive mechanism. When the drive mechanism drives the rotating block 33 to rotate, the rotating block 33 does not contact the limiting blocks 34, so it does not drive the rotating component 31 to rotate until the rotating block 33 continues to rotate and releases from the corresponding limiting block 34, after which the rotating component 31 is driven to rotate and drive the power generation coil module 1. The same process is achieved when the drive mechanism rotates in the opposite direction. Thus, the rotation travel of the rotating component 31 and the travel of the object's rotation are matched through the cooperation of the rotating block 33 and the limiting blocks 34.
[0040] The following detailed examples illustrate different application scenarios of the rotary self-generating device.
[0041] Example 1, refer to Figure 3A rotary self-generating power device 4 is applied to the door lock, using the self-generated electricity to drive a wireless transmitter to send different status signals of the door lock to the corresponding server. Specifically, the door lock uses a latch mechanism, and the rotary self-generating power device 4 is installed within the travel range of the latch 5. The rotating component 31 is equipped with a reset device, such as a reset spring. The locking tongue 5 is the driving mechanism. When the locking tongue 4 extends, it pushes the rotating block 33 to rotate and, through a limiting block 34, pushes the rotating component 31 to cause the power generation coil module 1 to separate from the magnetic body 2. The magnetic flux of the power generation coil module 1 changes, causing the coil winding 12 to generate electricity. As the power generation coil module 1 approaches another magnetic body 2, the magnetic flux of the power generation coil module 1 changes again, causing the coil winding 12 to generate electricity. When the locking tongue retracts, the reset spring drives the rotating block 33 to rotate in the opposite direction and, through another limiting block 34, pushes the rotating component 31 to cause the power generation coil module 1 to separate from the magnetic body 2. The magnetic flux of the power generation coil module 1 changes, causing the coil winding 12 to generate electricity.

The locking bolt 6 is the driving mechanism. When the locking bolt 6 extends, it pushes the rotating block 33 to rotate and, through a limiting block 34, pushes the rotating component 31 to cause the generating coil module 1 to separate from the magnetic body 2. The change in magnetic flux of the generating coil module 1 causes the coil winding 12 to generate electricity. As the generating coil module 1 approaches another magnetic body 2, the magnetic flux of the generating coil module 1 changes again, causing the coil winding 12 to generate electricity. When the locking bolt 6 retracts, the reset spring drives the rotating block 33 to rotate in the opposite direction and, through another limiting block 34, pushes the rotating component 31 to cause the generating coil module 1 to separate from the magnetic body 2.

The rotating shaft rotates in the opposite direction, driving the rotating block 33 to rotate in the opposite direction. Through another limit block 34, the rotating part 31 is pushed to cause the generating coil module 1 to separate from the magnetic body 2.
