Description

Technical Field

[0001] The present invention relates to the technical field of mechanical energy collection, and in particular to an omnidirectional electromagnetic mechanical energy collection device. Background Art

[0002] With the rapid development of social economy, the demand for sustainable power sources in various scenarios has increased, and general batteries cannot meet the demand for sustainable use. Existing electromagnetic generators are mainly divided into resonant generators and rotary generators. The direction of movement of the resonant generator is a straight line, and it can only collect mechanical vibration energy in the direction of the straight line for power generation, and there are certain requirements for the vibration frequency to achieve maximum power generation efficiency; the mechanical energy collection direction of the rotary generator is the entire plane where the rotation direction is located, but it cannot collect mechanical energy on other planes. Both of the above-mentioned generators cannot collect mechanical energy in multiple directions in the environment in real time, and the power conversion efficiency of the entire generator is low.

[0003] For example, the invention patent with application number CN114865873A discloses a spherical array permanent magnet vibration energy harvester, which is mainly composed of a large non-magnetic hollow sphere and a rolling groove, and a limited number of permanent magnets and induction coils are distributed on the two respectively. The large non-magnetic hollow sphere is located in the rolling groove, and the two can slide relative to each other. In this process, the vibration source comes from the rolling groove responding to low-frequency vibrations from the outside world, such as wave energy, human body movement energy, etc. The induction coil on the bottom side of the rolling groove induces the alternating magnetic field provided by the rolling in the non-magnetic hollow sphere to generate electrical energy. This collector can provide reliable and stable energy collection for swinging or composite low-frequency vibration sources, but the invention is large in size and has limited usage scenarios. Summary of the Invention

[0004] In response to the technical problem that existing energy harvesters cannot collect mechanical energy in the environment from multiple directions, the present invention proposes an omnidirectional electromagnetic mechanical energy harvesting device that can effectively convert the surrounding mechanical energy into electrical energy, which can power low-power electronic devices.

[0005] In order to achieve the above-mentioned purpose, the technical solution of the present invention is implemented as follows: an omnidirectional electromagnetic mechanical energy collection device includes a base, at least two grooves are provided on the base, energy collectors are provided in the grooves, at least two rectifier modules are provided inside the base, and the energy collectors are connected correspondingly to the rectifier modules.

[0006] The base is a polyhedral sphere, and an energy collector is arranged on each face of the polyhedral sphere.

[0007] The energy collector includes at least one permanent magnet and at least one induction coil. The groove includes a coil groove and a permanent magnet groove. A cover is fixedly provided on the upper side of the groove. The induction coil is fixedly provided on the base through the induction coil groove. The induction coil is connected to the rectifier module. A permanent magnet groove is provided on the upper side of the induction coil groove. The permanent magnet groove is connected to the induction coil groove. The permanent magnet is movably provided in the permanent magnet groove.

[0008] The permanent magnet groove and the induction coil groove are both circular grooves, the centers of the permanent magnet groove and the induction coil groove coincide with each other, and the radius of the permanent magnet groove is greater than the radius of the induction coil groove.

[0009] A cover is provided on the top of the permanent magnet groove. The cover has the same shape as the permanent magnet groove and is fixedly connected. The distance from the bottom of the cover to the induction coil is greater than the thickness of the permanent magnet.

[0010] The distance between the outer boundary of the induction coil and the outer boundary of the induction coil groove is smaller than the diameter of the permanent magnet.

[0011] The rectifier module is a rectifier bridge, which is arranged inside the substrate, and the induction coil is correspondingly connected to the rectifier bridge.

[0012] The method of use is: place the base in the usage scenario. When the base is subjected to external force, the base will move and roll. The energy collector converts the mechanical energy generated by the movement and rolling into an induced current, and the induced current is rectified into direct current through the rectifier bridge of the rectifier module.

[0013] The energy collector converts mechanical energy into induced current in the following way: under the action of inertia, the permanent magnet in the energy collector slides relative to the induction coil, thereby generating induced current.

[0014] The present invention places an energy collector on a polyhedral sphere. When the base is subjected to an external force, the base moves under the influence of the force. The permanent magnet within the energy collector slides relative to the coil, converting the mechanical energy applied to the base into electrical energy. The polyhedral sphere base is highly susceptible to movement when subjected to external forces, improving the energy conversion efficiency of the device. By placing multiple energy collectors on the base, the mechanical energy applied to the base drives the multiple energy collectors to generate electricity, effectively converting the surrounding mechanical energy into electrical energy, which can be used to power electronic devices.

[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without creative work are within the scope of protection of the present invention.

[0022] like Figure 1 The figure shows an omnidirectional electromagnetic mechanical energy harvesting device, comprising a base 1 with at least two grooves formed therein, each containing an energy harvester. A lid 2 is fixedly mounted above the grooves, and a rectifier module is mounted within the base 1. The energy harvester is connected to the input of the rectifier module. The energy harvester converts mechanical energy applied to the base 1 into electrical energy, while the lid 2 seals the energy harvester. The rectifier module converts the induced current collected by the energy harvester into direct current.

[0023] Specifically, the base 1 is a regular dodecahedron, with an energy collector disposed on each face of the dodecahedron. The energy collector comprises a permanent magnet 3 and an induction coil 4. The induction coil 4 is fixed to the base 1 via an induction coil groove 5. A permanent magnet groove 6 is disposed above the induction coil groove 5, communicating with the induction coil groove 5. The permanent magnet 3 is movably disposed within the permanent magnet groove 6. Both the permanent magnet groove 6 and the induction coil groove 5 are circular grooves, with their centers coinciding. This ensures that the permanent magnet 3's range of motion is above the induction coil 4. The radius of the permanent magnet groove 6 is greater than that of the induction coil groove 5, allowing the permanent magnet 3 to slide relative to the induction coil 4 over a larger range. The distance between the outer edges of the induction coil 4 and the outer edges of the induction coil groove 5 is less than the diameter of the permanent magnet 3, ensuring that the permanent magnet 3 remains above the induction coil 4 during movement, preventing mechanical energy from being wasted. The induction coil groove 5 primarily serves to secure the induction coil 4, preventing it from moving within the energy collector and affecting energy collection efficiency. The permanent magnet groove 6 is mainly used to provide a space for the permanent magnet 3 to move, so that when the base 1 is subjected to external force and moves, the permanent magnet 3 can slide relative to the induction coil 4, thereby converting the mechanical energy received by the base 1 into electrical energy. A lid 2 is provided on the top of the permanent magnet groove 6. The lid 2 is the same shape as the permanent magnet groove 6 and is fixedly connected to ensure that the energy collector is well sealed. The distance from the bottom of the lid 2 to the induction coil 4 is greater than the thickness of the permanent magnet 3, ensuring that the permanent magnet 3 can move freely in the permanent magnet groove 6, preventing the lid 2 from squeezing and obstructing the permanent magnet 3, causing waste of mechanical energy in the environment. The rectifier module is a rectifier bridge, which is arranged inside the base 1. The energy collector is connected to the rectifier bridge in a one-to-one correspondence. The main function of the rectifier bridge is to convert the electrical energy collected by the energy collector into direct current. The rectifier bridge can be connected to a battery to store electrical energy or directly connected to a low-power electrical appliance to supply power to the low-power electrical appliance.

[0024] The method of using the present invention is as follows: when the base 1 is placed in the usage scenario and the device is acted upon by an external force, the base 1 will move and roll, and the permanent magnet 3 in the energy collector will slide relative to the induction coil 4 under the action of inertia, thereby generating an induced current, which is rectified into direct current through a rectifier bridge to power low-power electrical equipment.

[0025] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
