Description

[Technical Field]

[0001] The present invention relates to a device that can realize self-power generation through rotation. [Background technology]

[0002] With the recent development and widespread adoption of the Internet of Things, there is a demand for installing sensors on various objects to monitor their status and transmitting corresponding status signals via wireless signals, thereby achieving intelligent coordination and automatic control. The sensors and wireless transmission require power, and installing batteries or other power sources is a common method. However, the batteries may run out, necessitating periodic maintenance, which is extremely inconvenient. Considering that the control signals that some objects attempt to transmit are relatively simple, and when these objects need to transmit a signal, a corresponding action, such as opening or closing a door lock, occurs. These actions can activate a self-powered device to generate electricity and trigger a wireless signal transmission circuit to transmit a signal. Conventional self-powered devices typically employ a coil winding with a movable magnetic core, which swings to contact different magnetic bodies, thereby changing the magnetic flux of the coil winding and generating electricity. However, the oscillation range of the magnetic core is limited to within the coil winding, and in order for the coil winding to generate a sufficient change in magnetic flux and generate sufficient power, the coil winding must be placed close to the magnetic core. Therefore, with this structure, the oscillation amplitude of the magnetic core is limited, the amount of power generated is relatively small, and it cannot drive electronic devices that consume relatively large amounts of power. Summary of the Invention [Problem to be solved by the invention]

[0003] This invention provides a device that uses a rotational method to drive a generating coil module or a magnetic body to generate power by itself. The entire device is linked to the action of the corresponding item to drive the generating coil module and the magnetic body of the self-generating device to generate relative rotation, thereby realizing induction power generation in the generating coil module and meeting the power supply needs of electrical equipment. [Means for solving the problem]

[0011] The rotary self-generating device is attached to a door body and connected to a lock body of the door body, the drive mechanism is a deadbolt, key cylinder, or lock bolt of the lock body, and the rotating member is further provided with a reset device. The drive mechanism drives the rotating block to rotate and pushes the rotating member via a limiting block, moving the generating coil module so as to separate from one magnetic body, thereby changing the amount of magnetic flux in the generating coil module and generating induction power in the coil winding. When the generating coil module approaches another magnetic body, the amount of magnetic flux in the generating coil module changes again, generating induction power in the coil winding. The drive mechanism is reset, and the reset device drives the rotating block to rotate in the opposite direction and pushes the rotating member via another limiting block, moving the generating coil module so as to separate from the magnetic body, thereby changing the amount of magnetic flux in the generating coil module and generating induction power in the coil winding. When the generating coil module approaches another magnetic body, the amount of magnetic flux in the generating coil module changes again, generating induction power in the coil winding.

[0012] The rotary self-generating device is mounted on a guide rail provided with bumps that abut against the rotating block, and the rotating member is further provided with a reset device. As the guide rail slides, the bumps drive the rotating block to rotate, pushing the rotating member via the limiting block to move the generating coil module away from one of the magnetic bodies, thereby changing the amount of magnetic flux in the generating coil module and generating induction power in the coil windings. When the generating coil module approaches another magnetic body, the amount of magnetic flux in the generating coil module changes again, generating induction power in the coil windings. The drive mechanism is reset, and the reset device drives the rotating block to rotate in the opposite direction, pushing the rotating member via the other limiting block to move the generating coil module away from the magnetic body, thereby changing the amount of magnetic flux in the generating coil module and generating induction power in the coil windings.

[0013] The rotary self-generating device is attached to a device having a rotating shaft, and the rotating shaft is connected to a rotating block to move the rotating block in rotation, and pushes the rotating member via a restricting block to move the generating coil module away from one magnetic body, thereby changing the amount of magnetic flux in the generating coil module and generating induction power in the coil winding.

The rotating shaft rotates in the opposite direction, driving the rotating block to rotate in the opposite direction, and pushes the rotating member via another restricting block to move the generating coil module away from the magnetic body, thereby changing the amount of magnetic flux in the generating coil module and generating induction power in the coil winding. When the generating coil module approaches another magnetic body, the amount of magnetic flux in the generating coil module changes again, generating induction power in the coil winding.

[0016] The rotary shaft is connected to a push switch, and the push switch and the rotary shaft are connected by a rack and a gear that mesh with each other.

[0018] The beneficial effect of this invention is that the power generating coil module and the magnetic body are moved by a driving mechanism to generate relative rotation, thereby changing the magnetic flux of the coil winding of the power generating coil module and generating electricity. Because the power generating coil module and the magnetic body are relatively separated in this invention, compared to the conventional structure that relies on the oscillation of a magnetic core, the power generating coil module and the magnetic body can adjust their relative positions according to the action needs of the item, thereby achieving self-power generation in accordance with the movement of the item, and generating enough power to meet the power supply needs of various electrical appliances.

[0020] The following description clearly and completely explains the concept, specific structure, and technical effects of the present invention with reference to the following examples and drawings, so that the objectives, solutions, and effects of the present invention can be fully understood. Furthermore, the examples and features of the examples in this application can be combined with each other without contradiction.

Furthermore, the terms up, down, left, right, top, bottom, etc., used in this invention only refer to the relative positions of the components of this invention in the drawings.

The terms used herein are for the purpose of describing specific examples only and are not intended to limit the present invention. As used herein, the term "and / or" includes any combination of one or more of the associated listed items.

[0023] In this disclosure, terms such as first, second, and third may be used to describe various elements, but it should be understood that these elements should not be limited to these terms. These terms are used only to distinguish elements of a common type from one another. For example, a first element may be referred to as a second element, and similarly, a second element may be referred to as a first element, without departing from the scope of this disclosure.

[0024] As shown in Fig. 1, the rotary self-power generating device comprises a power generating coil module 1, a magnetic body 2 and a reciprocating rotating device 3. The rotating device 3 is connected to a driving mechanism, which is a member corresponding to the movement formed during the action process of the related article, which will be described in detail below based on different embodiments.

[0025] One of the power generating coil module 1 and the magnetic body 2 is attached to the rotating device 3, while the other is attached in a relatively fixed position. When the two are gradually rotated by the rotating device 3 to the mating position, the coil module in the power generating coil module 1 cuts the magnetic field lines 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, cutting the magnetic field lines of the secondary strand and generating induced electricity. The induced electricity generated by the power generating coil module 1 is connected to electrical equipment via the output terminals.

[0026] To facilitate the integrated manufacturing of the rotary self-generating device of the present invention, the rotating device 3 includes a rotating member 31 and a fixed member 32, and the rotating member 31 is rotatably connected to the fixed member 32 via a rotation shaft. The generating coil module 1 and the magnetic body 2 are attached to the rotating member 31 and the fixed member 32, respectively, and then rotated by moving the rotating member 31 via a drive mechanism.

[0027] Specifically, the magnetic bodies 2 are mounted correspondingly on the rotating member 31, and the generating coil modules 1 are mounted correspondingly on the fixed member 32. The same effect can be achieved in the reverse case. However, the preferred technical solution of the present invention is to mount the generating coil modules 1 on the rotating member 31. Specifically, in order to increase the power generation capacity of the self-powered device, the coil windings 12 of the generating coil modules 1 are usually formed with a relatively large number of turns, so that the rotating member 31 has enough space to mount and fix the coil windings 12. At the same time, according to usage needs, a corresponding number of magnetic bodies 2, such as two groups, can be mounted on the fixed member 32. When the generating coil modules 1 approach different magnetic bodies 2, they can generate power inductively, thereby transmitting different positional states of the objects through corresponding reactive power generation signals.

[0028] The present inventors provide two types of structures for the generating coil module 1 to meet different usage needs. As shown in FIG. 1 , the generating coil module 1 is attached as a whole to the edge of a rotating member 31, and magnetic bodies 2 are installed on both sides of the generating coil module 1 at a predetermined interval. When the rotating member 31 moves the generating coil module 1 toward or away from two different magnetic bodies 2, induction power is generated. In another embodiment, as shown in FIG. 2 , the rotating member 31 is formed by the magnetic core 11 of the generating coil module 1, and the coil winding 12 is wound around the magnetic core 11, with a portion of the magnetic core 11 extending to a fixed member 32. The magnetic bodies 2 are installed on both sides of the magnetic core 11 extending to the fixed portion at a predetermined interval. When the extended magnetic core 11 comes into contact with or separates from the magnetic body 2, the changed amount of magnetic flux is guided to the coil winding 12 via the magnetic core 11, thereby generating induction power.

[0029] To adapt the rotation angle of the rotating member 31 to the movement stroke of different objects, the rotating member 31 is provided with a rotating block 33, which is rotatably connected to the rotating member 31 via a rotation shaft. The rotating member 31 is provided with two limiting blocks 34 for limiting the rotation width of the rotating block 33, and the rotation of the rotating block 33 is limited between the two limiting blocks 34. The rotating block 33 is connected to a driving mechanism. When the driving mechanism drives the rotating block 33 to rotate, it does not contact the limiting blocks 34. Therefore, the rotating block 33 continues to rotate until it is released from the corresponding limiting block 34. The rotating member 31 is then driven to rotate, moving the generating coil module 1. The same process is achieved when the driving mechanism rotates in the opposite direction. As a result, the rotation stroke of the rotating member 31 can be matched to the rotation stroke of the object by the interlocking of the rotating block 33 and the limiting blocks 34.

[0030] Hereinafter, different application scenarios of the rotary self-power generating device will be described in detail with specific examples.

[0031] In the first embodiment, referring to Fig. 3, a rotary self-powered device 4 is applied to a door lock, and the self-generated power drives a wireless transmitter to transmit different status signals of the door lock to a corresponding server. Specifically, the door lock adopts a deadbolt system, and the rotary self-powered device 4 is installed within the stroke of the deadbolt 5. The rotating member 31 is provided with a reset device such as a reset spring, and the deadbolt 5 is a drive mechanism. When the deadbolt 5 is extended, it drives the rotating block 33 to rotate, pushing the rotating member 31 via the restricting block 34 and moving the power generating coil module 1 so that it separates from one of the magnetic bodies 2. This changes the amount of magnetic flux in the power generating coil module 1, causing induction power to be generated in the coil winding 12. When the power generating coil module 1 approaches another magnetic body 2, the amount of magnetic flux in the power generating coil module 1 changes again, causing induction power to be generated in the coil winding 12. When the deadbolt is retracted, the reset spring drives the rotating block 33 to rotate in the opposite direction, pushing the rotating member 31 via the other restricting block 34 and moving the power generating coil module 1 so that it separates from the magnetic body 2. This changes the amount of magnetic flux in the power generating coil module 1, causing induction power to be generated in the coil winding 12. When the power generating coil module 1 approaches another magnetic body 2, the amount of magnetic flux in the power generating coil module 1 changes again, causing induction power to be generated in the coil winding 12.

[0032] In the second embodiment, referring to FIG. 4, the rotary self-generating device 4 is also applied to a door lock, which adopts a lock bolt 6, and the rotary self-generating device 4 is correspondingly mounted within the movement stroke of the lock bolt 6. The rotating member 31 is provided with a reset device such as a reset spring, and the lock bolt 6 is a drive mechanism. When the lock bolt 6 is extended, it drives the rotating block 33 to rotate, pushing the rotating member 31 via the restricting block 34 and moving the power generating coil module 1 so that it separates from one of the magnetic bodies 2. This changes the amount of magnetic flux in the power generating coil module 1, causing induction power to be generated in the coil winding 12. When the power generating coil module 1 approaches another magnetic body 2, the amount of magnetic flux in the power generating coil module 1 changes again, causing induction power to be generated in the coil winding 12. When the lock bolt 6 is retracted, the reset spring drives the rotating block 33 to rotate in the opposite direction, pushing the rotating member 31 via the other restricting block 34 and moving the power generating coil module 1 so that it separates from the magnetic body 2. This changes the amount of magnetic flux in the power generating coil module 1, causing induction power to be generated in the coil winding 12. When the power generating coil module 1 approaches another magnetic body 2, the amount of magnetic flux in the power generating coil module 1 changes again, causing induction power to be generated in the coil winding 12.

[0033] In the third embodiment, referring to FIG. 5 , the rotary self-power generating device 4 is also applied to a door lock. The door lock uses a rotary key cylinder. The rotary shaft of the key cylinder is connected to a rotary block 33, which drives the rotary block 33 to rotate and pushes the rotary member 31 via a restricting block 34, causing the generator coil module 1 to separate from one of the magnetic bodies 2. This changes the amount of magnetic flux in the generator coil module 1, generating induction power in the coil winding 12. When the generator coil module 1 approaches another magnetic body 2, the amount of magnetic flux in the generator coil module 1 changes again, generating induction power in the coil winding 12. The rotary shaft rotates in the opposite direction, driving the rotary block 33 to rotate in the opposite direction, which pushes the rotary member 31 via the other restricting block 34, causing the generator coil module 1 to separate from the magnetic body 2. This changes the amount of magnetic flux in the generator coil module 1, generating induction power in the coil winding 12. When the generator coil module 1 approaches another magnetic body 2, the amount of magnetic flux in the generator coil module 1 changes again, generating induction power in the coil winding 12.

[0034] In the fourth embodiment, referring to FIG. 6, the rotary self-generating device 4 is applied to the hinge rotation shaft of the door body, and the rotation shaft 71 of the hinge 7 is connected to the rotation block 33 via the gear transmission device 72, which moves the rotation block 33 to rotate and pushes the rotation member 31 via the limiting block 34 to move the generating coil module 1 away from one of the magnetic bodies 2, thereby changing the amount of magnetic flux in the generating coil module 1 and generating induction power in the coil winding 12. When the generating coil module 1 approaches another magnetic body 2, the generating coil module The amount of magnetic flux in the generator coil module 1 changes again, generating induction power in the coil winding 12, and the rotating shaft rotates in the opposite direction, driving the rotating block 33 to rotate in the opposite direction, pushing the rotating member 31 via another restricting block 34 and moving the generator coil module 1 so that it separates from the magnetic body 2, thereby changing the amount of magnetic flux in the generator coil module 1 and generating induction power in the coil winding 12. When the generator coil module 1 approaches another magnetic body 2, the amount of magnetic flux in the generator coil module 1 changes again, generating induction power in the coil winding 12.

[0035] In the fifth embodiment, referring to FIG. 7, the rotary self-generating device 4 is applied to a door closing device of a door body. The door hinge 8 of the door closing device is usually connected to the door closing device body via a rotary shaft. The rotary shaft is connected to a rotary block 33, which moves the rotary block 33 to rotate and pushes the rotary member 31 via a restricting block 34, moving the power generating coil module 1 to separate from one of the magnetic bodies 2. This changes the amount of magnetic flux in the power generating coil module 1, causing induction power generation in the coil winding 12, and moving the power generating coil module 1 closer to another magnetic body 2. When this occurs, the amount of magnetic flux in the power generating coil module 1 changes again, generating induction power in the coil winding 12, and the rotating shaft rotates in the opposite direction, driving the rotating block 33 to rotate in the opposite direction, pushing the rotating member 31 via another limiting block 34 and moving the power generating coil module 1 so that it separates from the magnetic body 2, thereby changing the amount of magnetic flux in the power generating coil module 1 and generating induction power in the coil winding 12.When the power generating coil module 1 approaches another magnetic body 2, the amount of magnetic flux in the power generating coil module 1 changes again, generating induction power in the coil winding 12.

[0036] In Example 6, referring to FIG. 8, a rotary self-power generating device 4 is applied to a rail-type push-pull device. The rotary self-power generating device 4 is attached to a guide rail 9 provided with a bump that contacts a rotating block 33. A reset device is further provided on the rotating member 31. As the guide rail 9 slides, the bump drives the rotating block 33 to rotate, and pushes the rotating member 31 via the limiting block 34, moving the power generating coil module 1 so as to separate from one of the magnetic bodies 2. This changes the amount of magnetic flux in the power generating coil module 1, causing induction power generation in the coil winding 12, and the power generating coil module When the power generating coil module 1 approaches another magnetic body 2, the amount of magnetic flux in the power generating coil module 1 changes again, causing induction power to be generated in the coil windings 12; the drive mechanism is reset; the reset device drives the rotating block 33 to rotate in the reverse direction, pushing the rotating member 31 via the other limiting block 34 and moving the power generating coil module 1 so that it separates from the magnetic body 2; thereby, the amount of magnetic flux in the power generating coil module 1 changes again, causing induction power to be generated in the coil windings 12; when the power generating coil module 1 approaches another magnetic body 2, the amount of magnetic flux in the power generating coil module 1 changes again, causing induction power to be generated in the coil windings 12.

[0037] In Example 7, referring to FIG. 9 , a rotary self-power generating device 4 is applied to a rotary switch device. The rotating shaft of the switch 10 is connected to a rotating block 33, which moves the rotating block 33 to rotate and pushes the rotating member 31 via a restricting block 34, causing the power generating coil module 1 to move away from one of the magnetic bodies 2, thereby changing the amount of magnetic flux in the power generating coil module 1 and generating induction power in the coil winding 12. When the power generating coil module 1 approaches another magnetic body 2, the amount of magnetic flux in the power generating coil module 1 changes again, causing induction power to be generated in the coil winding 12. The rotating shaft rotates in the opposite direction, driving the rotating block 33 to rotate in the opposite direction and pushing the rotating member 31 via the other restricting block 34, causing the power generating coil module 1 to move away from the magnetic body 2, thereby changing the amount of magnetic flux in the power generating coil module 1 and generating induction power in the coil winding 12. When the power generating coil module 1 approaches another magnetic body 2, the amount of magnetic flux in the power generating coil module 1 changes again, causing induction power to be generated in the coil winding 12.

[0038] In the eighth embodiment, referring to FIG. 10, the rotary self-power generating device 4 is applied to a push-type switch device, and the push-type switch 11 and the rotating shaft are connected by a meshing rack and gear. The gear is connected to the rotating block 33, and the rotating block 33 is moved to rotate, and the rotating member 31 is pushed via the limiting block 34, and the power generating coil module 1 is moved to separate from one of the magnetic bodies 2. As a result, the amount of magnetic flux in the power generating coil module 1 changes, and induction power is generated in the coil winding 12. When the power generating coil module 1 approaches another magnetic body 2, the power generating coil module 1 The amount of magnetic flux in generator coil module 1 changes again, causing induction power generation in coil winding 12. After the push switch is released, the rack moves the gear to rotate in the opposite direction, driving rotating block 33 to rotate in the opposite direction, pushing rotating member 31 via another limiting block 34 and moving power generating coil module 1 so that it separates from magnetic body 2. This causes a change in the amount of magnetic flux in generator coil module 1, causing induction power generation in coil winding 12. When generator coil module 1 approaches another magnetic body 2, the amount of magnetic flux in generator coil module 1 changes again, causing induction power generation in coil winding 12.

[0039] In the ninth embodiment, referring to FIG. 11, the rotary self-generating device 4 is applied to a parking brake device of an automobile. The parking brake handle 101 is connected to the rotating block 33 via a gear device. When the parking brake handle 101 is pulled, the rotating block 33 is moved to rotate, and the rotating member 31 is pushed via the restricting block 34, so that the generating coil module 1 is moved to separate from one of the magnetic bodies 2. This changes the amount of magnetic flux in the generating coil module 1, causing induction power generation in the coil winding 12. When the generating coil module 1 approaches another magnetic body 2, the generating coil module The amount of magnetic flux in the generator coil module 1 changes again, causing induction power generation in the coil winding 12. When the handbrake handle 101 is released, the gear device rotates in the reverse direction, driving the rotating block 33 to rotate in the reverse direction, pushing the rotating member 31 via the other restricting block 34 and moving the generator coil module 1 so that it separates from the magnetic body 2. This causes a change in the amount of magnetic flux in the generator coil module 1, causing induction power generation in the coil winding 12. When the generator coil module 1 approaches another magnetic body 2, the amount of magnetic flux in the generator coil module 1 changes again, causing induction power generation in the coil winding 12.

The rotating shaft of the shift pedal 102 is connected to the rotating block 33, which moves the rotating block 33 to rotate and pushes the rotating member 31 via the restricting block 34, causing the generating coil module 1 to move away from one of the magnetic bodies 2. This changes the amount of magnetic flux in the generating coil module 1, generating induction power in the coil winding 12. When the generating coil module 1 approaches another magnetic body 2, the amount of magnetic flux in the generating coil module 1 changes again, generating induction power in the coil winding 12. The rotating shaft rotates in the opposite direction, driving the rotating block 33 to rotate in the opposite direction, which pushes the rotating member 31 via the other restricting block 34, causing the generating coil module 1 to move away from the magnetic body 2. This changes the amount of magnetic flux in the generating coil module 1, generating induction power in the coil winding 12. When the generating coil module 1 approaches another magnetic body 2, the amount of magnetic flux in the generating coil module 1 changes again, generating induction power in the coil winding 12.
