Description

Technical Field

[0001] The invention relates to a device capable of realizing self-generation of electricity by rotation. Background Art

[0002] With the continuous development and popularization of the Internet of Things in recent years, it is necessary to monitor the status of different items by adding sensors and transmit corresponding status signals through wireless signals, so as to realize the needs of intelligent linkage and automatic control. Sensors and wireless transmission require power supply to complete, and the more common method is to add batteries for power supply. However, the battery power may be exhausted, and personnel are required to perform regular maintenance, which will cause many inconveniences. Considering that the control signals that need to be sent by some items are relatively simple and these items usually produce corresponding actions when they need to send signals, such as opening and closing of door locks, etc., these actions can drive the self-generating device to generate electricity and trigger the wireless signal transmission circuit to send signals. The more common self-generating devices usually use coil windings with active magnetic cores to contact different magnetic bodies through the swing of the magnetic core to change the magnetic flux of the coil winding and generate electricity. However, since the swing of the magnetic core can only be limited to the coil winding, and the coil winding must be relatively close to the magnetic core to generate enough electricity to form a sufficient magnetic flux change, the structure limits the swing amplitude of the magnetic core, and its power generation is relatively small and cannot drive some electronic devices with relatively large power consumption.

The term "and / or" used herein includes any combination of one or more related listed items.

[0022] It should be understood that, although the terms first, second, third, etc. may be used to describe various elements in the present disclosure, these elements should not be limited to these terms. These terms are only used to distinguish elements of the same type from each other. For example, without departing from the scope of the present disclosure, the first element may also be referred to as the second element, and similarly, the second element may also be referred to as the first element.

[0023] like Figure 1 As shown, the rotary self-generating device comprises a 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 corresponding moving part formed during the movement of the related object, and will be described in detail according to different embodiments below.

[0024] One of the generating coil module 1 and the magnetic body 2 is installed on the rotating device 3, and the other can be installed in a relatively fixed position. When the two are gradually rotated to a fitting position by the rotating device 3, the coil module in the generating coil module 1 cuts the magnetic force lines of the magnetic body 2 to generate 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 force lines of the secondary new stock to generate induced electricity. The induced electricity generated by the generating coil module 1 is connected to the electrical equipment through the output terminal.

[0025] In order to facilitate the integrated production 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 rotating shaft. The power generation coil module 1 and the magnetic body 2 are respectively installed on the rotating member 31 and the fixed member 32, and then the rotating member 31 is driven to rotate by the driving mechanism.

[0026] Specifically, the magnetic body 2 can be installed on the rotating member 31, and the generating coil module 1 can be installed on the fixing member 32 accordingly. The same effect can be achieved in the opposite manner. However, the preferred solution of the present invention is to install the generating coil module 1 on the rotating member 31, specifically to increase the power generation of the self-generating device. The coil winding 12 of the generating coil module 1 usually needs to be wound with a large number of turns, so there is enough space on the rotating member 31 for installing and fixing the coil winding 12. At the same time, a corresponding number of magnetic bodies 2 can be installed on the fixing member 32 according to the needs of use, such as two groups. When the generating coil module 1 is close to different magnetic bodies 2, it can generate electricity by induction, thereby sending out different position states of the object through corresponding reaction power generation signals.

[0027] The inventor provides two structures of the generating coil module 1 to meet different usage requirements. Figure 1 As shown, the generating coil module 1 is integrally mounted on the edge of the rotating member 31, and the magnetic bodies 2 are arranged on both sides of the generating coil module 1 according to a set interval. When the rotating member 31 drives the generating coil module 1 to approach or leave two different magnetic bodies 2, induction power generation will be generated. Figure 2 As shown, the rotating member 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 fixed part 32, and the magnetic body 2 is arranged on both sides of the magnetic core 11 extending to the fixed position according to a set interval. The extended magnetic core 11 contacts or separates from the magnetic body 2, and the changing magnetic flux is guided to the coil winding 12 through the magnetic core 11, thereby generating induction power generation.

[0028] In order to make the rotation angle of the rotating member 31 adaptable to the action stroke of different objects, a rotating block 33 is provided on the rotating member 31, and the rotating block 33 is rotatably connected to the rotating member 31 through a rotating shaft. The rotating member 31 is provided with two limit blocks 34 for limiting the rotation amplitude of the rotating block 33, and the rotation of the rotating block 33 is limited between the two limit blocks 34. The rotating block 33 is connected to the driving mechanism. When the driving mechanism drives the rotating block 33 to rotate, the rotating block 33 does not contact the limit blocks 34, so it will not drive the rotating member 31 to rotate, until the rotating block 33 continues to rotate and is released from the corresponding limit blocks 34, and then drives the rotating member 31 to rotate and drive the generating coil module 1. When the driving mechanism rotates in the opposite direction, the above process is also realized. Therefore, the rotation stroke of the rotating member 31 can be matched with the action stroke of the rotation generated by the object through the cooperation of the rotating block 33 and the limit blocks 34.

When the lock tongue 4 is extended, the rotating block 33 is pushed to rotate and the rotating member 31 is pushed through a limit block 34 to drive the power generation coil module 1 to separate from the magnetic body 2 therein, and the magnetic flux of the power generation coil module 1 changes so that the coil winding 12 generates inductive power. As the power generation coil module 1 approaches another magnetic body 2, the magnetic flux of the power generation coil module 1 changes again so that the coil winding 12 generates inductive power. When the lock tongue is retracted, the reset spring drives the rotating block 33 to rotate in the opposite direction and pushes the rotating member 31 through another limit block 34 to drive the power generation coil module 1 to separate from the magnetic body 2.
