Description

Technical Field

[0001] The utility model relates to the technical field of micro power generation, and particularly relates to a single magnet self-power generation device. Background Art

[0002] At present, the micro power generation products on the market use the pressing force of hands or external micro mechanical pressure to provide alternative solutions for small low-power electronic products. However, these products usually include two magnets respectively installed at both ends of a coil, two magnetic conduction plates, the coil, and a magnetic conduction sheet arranged at the center of the coil. The two ends of the magnetic conduction plates are in contact with the two magnets to conduct magnetism, so that the magnetic conduction sheet located at the center of the coil can swing up and down and contact the magnetic conduction plates to conduct magnetism. When the magnetic conduction sheet swings, a magnetic field change occurs to generate electricity in the coil.

[0003] However, in actual use, due to the setting of two magnets, the lengths of the magnetic conduction plates and the magnetic conduction sheet will be correspondingly elongated, resulting in a longer length and a larger volume of the product.

[0039] Such as Figures 1-8A single-magnet self-power generation device shown in the figure includes a bracket 1, a coil 2, a first magnetic conduction plate 3, a second magnetic conduction plate 4, a magnetic conduction swing plate 5, and a permanent magnet 6; a cavity 11 with both ends open is provided inside the bracket 1, and two swing fulcrums 18 for swinging are provided on the upper and lower walls inside the cavity 11, and the two swing fulcrums 18 correspond to each other vertically; the coil 2 is wound around the bracket 1; the first magnetic conduction plate 3 is provided with a lower left protrusion at the left end of the cavity 11 and a lower right protrusion at the right end of the cavity 11, the second magnetic conduction plate 4 is provided with an upper left protrusion at the left end of the cavity 11 and an upper right protrusion at the right end of the cavity 11, and the first magnetic conduction plate 3 and the second magnetic conduction plate 4 are symmetrically arranged on the upper and lower sides of the bracket 1; there is one permanent magnet 6 and it is located at one end of the bracket 1, the top of the permanent magnet 6 abuts against the first magnetic conduction plate 3, and the bottom of the permanent magnet 6 abuts against the second magnetic conduction plate 4; the magnetic conduction swing plate 5 is arranged in the cavity 11 and between the two swing fulcrums 18, and one end of the magnetic conduction swing plate 5 extends out of the cavity 11, and the other end of the magnetic conduction swing plate 5 is located between the lower right protrusion and the upper right protrusion, or the other end of the magnetic conduction swing plate 5 is located between the lower left protrusion and the upper left protrusion; the magnetic conduction swing plate 5 can swing up and down in the cavity 11 to abut against the lower left protrusion and the upper right protrusion or the lower right protrusion and the upper left protrusion to realize magnetic conduction.

[0040] Based on the above structure, there is one permanent magnet 6 and it is located at one end of the bracket 1, and the top of the permanent magnet 6 abuts against the first magnetic conduction plate 3 to conduct magnetism, and the bottom of the permanent magnet 6 abuts against the second magnetic conduction plate 4 to realize magnetic conduction; the magnetic conduction swing plate 5 swings up and down with the two swing fulcrums 18 as the support points in the cavity 11, and abuts against the lower left protrusion and the upper right protrusion to realize magnetic conduction, or abuts against the lower right protrusion and the upper left protrusion to realize magnetic conduction, so that the magnetic field of the magnetic conduction swing plate 5 changes, and the coil 2 wound around the bracket 1 induces the changing magnetic field to generate electricity, providing the required power supply for its low-power electronic devices; there is only one permanent magnet 6, which shortens the length of the product, and at the same time the lengths of the magnetic conduction swing plate 5, the first magnetic conduction plate 3 and the second magnetic conduction plate 4 are correspondingly shortened, so that the lower left protrusion and the upper left protrusion or the lower right protrusion and the upper right protrusion are retracted inside the open side wall of the cavity 11, thereby reducing the swing amplitude of the magnetic conduction swing plate 5 to realize magnetic conduction, reducing the pressing depth of the user, improving the user experience, and at the same time reducing the volume of the product and lowering the production and manufacturing cost.

[0041] It should be noted that in this embodiment, the permanent magnet 6 has a relatively large volume to meet the magnetic force requirement while not affecting the size length and volume of the product, ensuring that the magnetic field changes when the magnetic conduction swing plate 5 swings, and the electricity generated by the coil 2 inducing the magnetic field change will not affect the power supply during its use.

[0042] Among them, the upper and lower parts on the left side of the bracket 1 are respectively provided with a first buckle 12 and a second buckle 121. A first slot 31 for clamping with the first buckle 12 is opened at the left end of the first magnetic conduction plate 3, and a second slot 41 for clamping with the second buckle 121 is opened at the left end of the second magnetic conduction plate 4.

The right end of the first magnetic conduction plate 3 is inserted into the first slot, and the right end of the second magnetic conduction plate 4 is inserted into the second slot to achieve fixation.

[0043] Further, the front and back of the top of the right side of the bracket 1 are respectively provided with a first buckle position 15 and a second buckle position 151. The interval between the first buckle position 15 and the second buckle position 151 forms the first slot. The front and back of the bottom of the right side of the bracket 1 are respectively provided with a third buckle position 16 and a fourth buckle position 161. The interval between the third buckle position 16 and the fourth buckle position 161 forms the second slot.

[0044] Specifically, the front and back of the right end of the first magnetic conduction plate 3 are also respectively provided with a first avoidance groove 35 and a second avoidance groove 36, so that the right end of the first magnetic conduction plate 3 forms a first insertion block and is inserted into the first slot. The front and back of the right end of the second magnetic conduction plate 4 are also respectively provided with a third avoidance groove 45 and a fourth avoidance groove 46, so that the right end of the second magnetic conduction plate 4 forms a second insertion block and is inserted into the second slot. During installation, the first magnetic conduction plate 3 is clamped with the first buckle 12 provided on the bracket 1 through the first slot 31, and then is inserted into the first slot formed by the interval between the first buckle position 15 and the second buckle position 151 on the bracket 1 through the first insertion block formed at the right end of the first magnetic conduction plate 3 to achieve fixation at the top of the bracket 1. The second magnetic conduction plate 4 is clamped with the second buckle 121 provided on the bracket 1 through the second slot 41, and then is inserted into the second slot formed by the interval between the third buckle position 16 and the fourth buckle position 161 on the bracket 1 through the second insertion block formed at the right end of the second magnetic conduction plate 4 to achieve fixation at the bottom of the bracket 1.

[0045] It should be noted that the structures of the first magnetic conduction plate 3 and the second magnetic conduction plate 4 are the same. As Figures 7-8 shown, at the same time, the upper and lower structures of the bracket 1 are symmetrically arranged. When the first magnetic conduction plate 3 and the second magnetic conduction plate 4 are respectively installed on the top and bottom of the bracket 1, they are symmetrically arranged on the upper and lower sides of the bracket 1.

[0046] Among them, a jack 141 and an installation groove 14 are provided on the right side of the bracket 1. The other end of the magnetic conduction swing plate 5 extends out of the cavity 11 and is located in the jack 141. Both the lower right protrusion and the upper right protrusion are inserted into the jack 141. The permanent magnet 6 is installed in the installation groove 14. And when the first magnetic conduction plate 3 and the second magnetic conduction plate 4 are respectively installed on the upper and lower sides of the bracket 1, the lower surface of the right end of the first magnetic conduction plate 3 abuts against the top of the permanent magnet 6 to achieve magnetic conduction, and the lower surface of the right end of the second magnetic conduction plate 4 abuts against the bottom of the permanent magnet 6 to achieve magnetic conduction.

[0047] Refer toFigure 2 , the single - magnet self - generating device of the present utility model further includes a shrapnel 7 arranged at one end of the magnetic - conduction swing plate 5. When the shrapnel 7 acts, it can drive the magnetic - conduction swing plate 5 to swing up and down in the cavity 11, so that the magnetic - conduction swing plate 5 abuts against the lower - left protrusion and the upper - right protrusion to achieve magnetic conduction; or the magnetic - conduction swing plate 5 abuts against the upper - left protrusion and the lower - right protrusion to achieve magnetic conduction. Thus, the magnetic force on the magnetic - conduction swing plate 5 changes, that is, the magnetic field changes, and the coil 2 induces the change of its magnetic field to generate electricity and provides the required power supply for low - power electronic devices.

[0048] Specifically, a first connection hole 51 is opened at one end of the magnetic - conduction swing plate 5, and a second connection hole 71 is opened on the shrapnel 7. The shrapnel 7 is fixed to the left end of the magnetic - conduction swing plate 5 by a fastener 8 passing through the first connection hole 51 and the second connection hole 71.

[0049] It should be noted that in this embodiment, the first connection hole 51 and the second connection hole 71 can be screw holes, and the fastener 8 is a screw, which passes through the first connection hole 51 and the second connection hole 71 and is fastened to fix the shrapnel 7 at one end of the magnetic - conduction swing plate 5. At the same time, the first connection hole 51 and the second connection hole 71 can also be through - holes, and the fastener 8 is a rivet, which passes through the first connection hole 51 and the second connection hole 71 and is riveted to fix the shrapnel 7 at one end of the magnetic - conduction swing plate 5. Here, no specific limitation is made.

[0050] Specifically, in this embodiment, an elastic member with a reset function, such as a spring, a torsion spring or a reset elastic steel sheet, etc., can be installed at the left end of the shrapnel 7;

[0051] Refer to Figures 3-4 , during operation, when the shrapnel 7 is pressed down, it drives one end of the magnetic - conduction swing plate 5 to swing downward and abut against the upper - left protrusion for magnetic conduction. At the same time, under the action of the fulcrum 18 in the cavity 11, the other end of the magnetic - conduction swing plate 5 swings upward and abuts against the lower - right protrusion for magnetic conduction, thus forming a first magnetic field; when the shrapnel 7 swings upward, it can drive one end of the magnetic - conduction swing plate 5 to swing upward and abut against the lower - left protrusion for magnetic conduction. At the same time, under the action of the fulcrum in the cavity 11, the other end of the magnetic - conduction swing plate 5 swings downward and abuts against the upper - right protrusion for magnetic conduction, thus forming a second magnetic field with a direction opposite to that of the first magnetic field. The coil 2 induces the changing magnetic field to generate electricity, and the electricity generated by the coil 2 can provide the required power supply for low - power electronic devices. Magnetic force changes occur at both ends of the magnetic - conduction swing plate 5, and the power generation amount is large.

[0052] It should be noted that in this embodiment, refer to Figures 3-4, on both sides of the fulcrum 18 inside the cavity 11, there are also inclined planes (not marked in the figure). These inclined planes can make the bottoms of the lower left protrusion, upper left protrusion, lower right protrusion, and upper right protrusion extend out of the opening of the cavity 11, so as to prevent the magnetically conductive swing plate 5 from contacting the inner wall of the cavity 11 during the swinging process, resulting in improper contact between the magnetically conductive swing plate 5 and the lower left protrusion, upper left protrusion, lower right protrusion, and upper right protrusion, and affecting the magnetic conduction effect when the magnetically conductive swing plate 5 contacts the lower left protrusion, upper left protrusion, lower right protrusion, and upper right protrusion.

When the first magnetically conductive plate 3 is installed on the top of the bracket 1, the first boss 13 extends into the first clearance hole 32; the second magnetically conductive plate 4 is provided with a second clearance hole 42, and the bottom of the bracket 1 is provided with a second boss 131. When the second magnetically conductive plate 4 is installed at the bottom of the bracket 1, the second boss 131 extends into the second clearance hole 42.

[0054] Furthermore, the left end of the first magnetically conductive plate 3 is provided with a first flanging 33 that is folded downward and a second flanging 34 that is folded downward on the right side of the first clearance hole 32. The first flanging 33 forms a lower left protrusion, and the second flanging 34 forms a lower right protrusion; the left end of the second magnetically conductive plate 4 is provided with a third flanging 43 that is folded upward and a fourth flanging 44 that is folded upward on the right side of the second clearance hole 42. The third flanging 43 forms an upper left protrusion, and the fourth flanging 44 forms an upper right protrusion.

[0055] Among them, when the first boss 13 extends into the first clearance hole 32, the right side of the first boss 13 contacts the second flanging 34; when the second boss 131 extends into the second clearance hole 42, the right side of the second boss 131 contacts the fourth flanging 44. Specifically, the first card slot 31 is opened at the folding part of the first flanging 33; the second card slot 41 is opened at the folding part of the third flanging 43.

[0056] Specifically, the bracket 1 is further provided with a plurality of positioning protrusions 17, and the plurality of positioning protrusions 17 are used to position or snap-install the single-magnet self-generating device of the present invention on a low-power electronic device.

[0057] It should be noted that in this embodiment, the low-power electronic device can be a wireless switch or a wireless doorbell, etc.

[0058] In summary, for the single-magnet self-power generation device of the present utility model, only one permanent magnet 6 is provided, which shortens the length of the product. The first flanging 33 and the third flanging 43 or the second flanging 34 and the fourth flanging 44 are retracted inside the open side wall of the cavity 11, thereby reducing the swing amplitude when the magnetic conduction swing plate 5 abuts against the first flanging 33 and the third flanging 43 or the second flanging 34 and the fourth flanging 44 to achieve magnetic conduction, reducing the user's pressing depth, enhancing the user experience, while reducing the volume of the product and lowering the production and manufacturing costs.

[0059] For the single-magnet self-power generation device of the present utility model, the first magnetic conduction plate 3 is clamped to the first buckle 12 at the top of the bracket 1 through the first card slot 31. The right end of the first magnetic conduction plate 3 is inserted into the first slot opened at the top of the bracket 1 and fixed to abut against the top of the permanent magnet 6 to achieve magnetic conduction; the second magnetic conduction plate 4 is clamped to the second buckle 121 at the top of the bracket 1 through the second card slot 41. The right end of the second magnetic conduction plate 4 is inserted into the second slot opened at the top of the bracket 1 and fixed to abut against the bottom of the permanent magnet 6 to achieve magnetic conduction. The magnetic conduction swing plate 5 swings to generate a change in magnetic force, causing the coil 2 to generate electricity. It has the advantages of simple structure, few components, and easy assembly, thus simplifying the production process and reducing the manufacturing cost; at the same time, the advantages of simple structure and easy assembly also improve the reliability and durability of the device, and provide the required power supply for low-power electronic devices to meet the long-term use requirements and significantly enhance the user experience.
