Description

Technical Field

[0001] This utility model relates to the field of generator technology, and in particular to a novel push-button generator that generates electromagnetic induction power based on kinetic energy pressing. Background Technology

[0002] In daily life and industrial applications, push-button generators, as convenient energy conversion devices, are widely used for powering small electronic devices and providing emergency power generation. However, existing push-button generators generally have the following shortcomings:

[0003] The power generation efficiency is low because the magnetic field strength is insufficient and the cutting effect of the magnetic field lines is poor, resulting in a low efficiency of converting kinetic energy into electrical energy.

[0004] Poor structural stability makes it prone to component wear and deformation after long-term use, leading to a decline in power generation performance;

[0005] It lacks environmental friendliness, with some materials containing harmful substances or causing pollution during the production process, and does not meet the requirements of green development.

[0006] Therefore, this utility model proposes a novel push-button generator, which solves the above problems through optimized structural design. Utility Model Content

[0007] This invention aims to solve the problems of low power generation efficiency, poor structural stability, and lack of environmental friendliness of existing push-button generators.

[0008] To achieve the above objectives, the present invention adopts the following technical solution:

[0009] A novel push-button generator includes a coil support, a pressure rod, a pressure plate, a coil, a magnet, and a magnetic conductive sheet. The coil support has a cavity and a support bar. The pressure rod is installed in the cavity, with its middle part supported by the support bar to form a lever fulcrum. The coil is wound around the outside of the coil support and surrounds the pressure rod, with terminals installed at both ends of the coil. A magnet is installed at the tail end of the pressure rod, and a pressure plate is installed at the front end. The coil is wrapped with a magnetic conductive sheet, which includes an N-pole magnetic conductive sheet and an S-pole magnetic conductive sheet. The N-pole magnetic conductive sheet abuts against the N-pole of the magnet and is bent to form a first contact portion and a second contact portion. The S-pole magnetic conductive sheet abuts against the S-pole of the magnet and is bent to form a third contact portion and a fourth contact portion. The first and second contact portions are located above the ends of the pressure rod, and the third and fourth contact portions are located below the ends of the pressure rod. The N-pole magnetic conductive sheet, the pressure rod, and the S-pole magnetic conductive sheet together guide the magnetic field lines to form a closed loop.

[0010] Furthermore, the pressure plate is an elastic pressure plate made of stainless steel high-elasticity metal material to ensure smooth reciprocating motion of the pressure rod.

[0011] Furthermore, the pressure rod and magnetic sheet are made of DT4 series electromagnetic pure iron. DT4 series electromagnetic pure iron has excellent soft magnetic properties, low coercivity and high permeability, resulting in low magnetic circuit loss. At the same time, it has strong antimagnetic aging ability. After adding elements such as aluminum, it reduces magnetic decay during long-term use, extends the service life of the equipment, and has good processing adaptability. It can be made into the required specifications through hot rolling, cold rolling and other processes.

[0012] Furthermore, the magnet is a neodymium iron boron magnet, which has high-performance magnetism and extremely high magnetic energy. It can generate a strong magnetic field in a small volume, which greatly improves the power density and efficiency of the equipment, and realizes the miniaturization and weight reduction of the equipment. Compared with traditional high-performance magnets (such as samarium cobalt magnets), it has lower cost and is suitable for large-scale industrial applications, reducing the production cost of downstream products.

[0013] Furthermore, the coil is made of copper, which has high electrical conductivity, with a conductivity of approximately 58.5 × 10⁻⁶ at 20°C. 6 With a thermal conductivity of S / m, second only to silver (although silver is extremely expensive), copper is currently the most commonly used conductive material in industry. It also has high thermal conductivity, with a thermal conductivity coefficient of approximately 401 W / (m·K), far exceeding that of steel and aluminum. It is an ideal heat-conducting medium that can dissipate the heat generated during coil operation in a timely manner, ensuring stable power generation efficiency. Furthermore, copper has high ductility, with an elongation rate of over 45%, and can be processed into extremely fine wires (such as enameled wire with a diameter of only 0.01 mm), making it suitable for coil winding.

[0014] Furthermore, the coil support is made of PPS+GF plastic material. PPS+GF plastic material has high rigidity and impact resistance. The addition of glass fiber significantly improves the tensile strength, flexural strength and elastic modulus of the material, effectively absorbing and dispersing impact energy, and improving the problem of insufficient toughness of pure PPS. Especially in high temperature environments, it can still maintain good impact resistance. It has good high temperature resistance and thermal shock resistance. The long-term service temperature of pure PPS is about 200-220℃. After adding glass fiber, the heat distortion temperature (HDT, under a load of 1.82MPa) of the material can be increased to 260-280℃, and it can withstand high temperatures above 300℃ for a short period of time. It has strong acid solubility and hydrolysis resistance, and can withstand long-term corrosion from strong acids, strong alkalis, greases, fuels and organic solvents. It is not easy to absorb water and swell or hydrolyze and degrade in humid or high-temperature water vapor environments, making it suitable for structural components in humid conditions. At the same time, it has the advantages of low shrinkage and low warpage, high insulation strength and arc resistance, ensuring the structural stability of the coil support and providing reliable support for each component.

[0015] Furthermore, by pressing the pressure plate to drive the pressure rod to deflect, the magnetic field lines of the magnet switch between the contact areas of the two-stage magnetic conductive plates, achieving two-stage magnetic field line cutting for power generation. The specific working principle is as follows: When the pressure plate is pressed down, the tail end of the pressure rod abuts against the first contact area of ​​the N-pole magnetic conductive plate, and the front end of the pressure rod abuts against the fourth contact area of ​​the S-pole magnetic conductive plate. This causes the magnetic field lines of the magnet to start from the N-pole and sequentially pass through the first contact area with the N-pole magnetic conductive plate, the pressure rod, and the fourth contact area of ​​the S-pole magnetic conductive plate, returning to the S-pole of the magnet. When the pressure plate is pressed up, the tail end of the pressure rod abuts against the third contact area of ​​the S-pole magnetic conductive plate, and the front end of the pressure rod abuts against the second contact area of ​​the N-pole magnetic conductive plate. This causes the magnetic field lines of the magnet to start from the N-pole and sequentially pass through the second contact area with the N-pole magnetic conductive plate, the pressure rod, and the third contact area of ​​the S-pole magnetic conductive plate, returning to the S-pole of the magnet. This two-stage switching method increases the number and intensity of magnetic field line cutting, improving power generation efficiency.

[0016] Optionally, a return spring is installed at the front end of the pressure bar, so that the pressure bar can automatically spring back to its original position after the pressure plate is pressed and released.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] High power generation efficiency: It uses neodymium iron boron magnets to provide a strong magnetic field, DT4 magnetic sheets to enhance the magnetic field focusing effect, and copper coils with excellent conductivity. Combined with a two-stage magnetic induction wire cutting design, it significantly improves the kinetic energy to electrical energy conversion efficiency.

[0019] Stable and durable structure: The coil support is made of PPS+GF plastic, which is resistant to high temperature, impact and low deformation; the pressure rod and magnetic sheet are made of DT4 pure iron, which has strong anti-magnetic aging ability, reduces performance degradation after long-term use and extends service life; the pressure plate is made of stainless steel high elastic metal material to ensure the stability and durability of reciprocating motion.

[0020] Environmentally friendly and energy-saving: All materials emit no harmful substances, and the production process generates no wastewater or toxic gases; it does not require external energy sources such as fuel or electricity during operation, relying solely on kinetic energy, which aligns with the concept of green environmental protection.

[0021] Wide applicability: Compact structure and light weight, suitable for various scenarios (such as portable electronic devices, emergency lighting switches, smart wearable devices, automotive emergency power supply components, etc.), excellent material processing performance, and easy to mass-produce.

Detailed Implementation

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0030] To make the technical solution and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0031] Please see Figures 1-6 As shown, this utility model discloses a novel push-button generator, including a coil bracket 1, a pressure rod 2, a pressure plate 3, a coil 4, a magnet 5, and a magnetic conductive sheet 6.

[0032] The coil support 1 is made of PPS+GF plastic material by injection molding. It has a cavity 11 and a support bar 12. The support bar 12 is located inside the cavity 11 and is used to support the pressure rod 2.

[0033] The pressure rod 2 is made of DT4 electromagnetic pure iron and is installed in the cavity 11. Its middle part abuts against the support bar 12, so that the pressure rod 2 can rotate around the support bar 12 to form a lever structure.

[0034] The pressure plate 3 is made of stainless steel high elastic metal material and is fixedly installed at the front end of the pressure rod 2. By applying an upward or downward force to the pressure plate 3, the pressure rod 2 can be driven to rotate around the support bar 12 within the cavity 11 at a certain angle.

[0035] The coil 4 is made of copper enameled wire wound around the outside of the coil bracket 1 and around the pressure rod 2. The two ends of the coil 4 are connected to terminals 41 for outputting the generated electrical energy.

[0036] Magnet 5 is a neodymium iron boron magnet, which is installed at the tail end of the pressure rod 2 to provide a strong magnetic field.

[0037] The magnetic conductor 6 includes an N-pole magnetic conductor 61 and an S-pole magnetic conductor 62, both made of DT4 electromagnetic pure iron, and is wrapped around the coil 4. The N-pole magnetic conductor 61 abuts against the N-pole of the magnet 5 and is bent to form a first contact portion 611 and a second contact portion 612; the S-pole magnetic conductor 62 abuts against the S-pole of the magnet 5 and is bent to form a third contact portion 621 and a fourth contact portion 622. The first contact portion 611 and the second contact portion 612 are located above both ends of the pressure rod 2, and the third contact portion 621 and the fourth contact portion 622 are located below both ends of the pressure rod 2.

[0038] In some embodiments, a return spring is installed at the front end of the pressure rod 2, so that the pressure rod 2 can automatically spring back to its original position after the pressure plate 3 is pressed and released.

[0039] In some embodiments, the magnetic conductive sheet 6 is made of DT4 electromagnetic pure iron, laser-cut to a thickness of 0.8 mm, with a permeability consistent with the pressure rod 2 to reduce magnetic resistance. The N-pole magnetic conductive sheet 61 is generally L-shaped, with a longitudinal portion 12 mm long and 5 mm wide; the transverse portion extends to form a first contact portion 611 and a second contact portion 612, wherein the first contact portion 611 is located above the tail end of the pressure rod 2, 8 mm from the center of the support bar 12, and the second contact portion 612 is located above the front end of the pressure rod 2, 8 mm from the center of the support bar 12. The S-pole magnetic conductive sheet 62 has a structure symmetrical to the N-pole magnetic conductive sheet 61, with a third contact portion 621 located below the tail end of the pressure rod 2 and a fourth contact portion 622 located below the front end of the pressure rod 2, with a vertical distance of 4 mm from the corresponding N-pole contact portion. The surface of the magnetic conductive sheet 6 is electroplated with tin, which enhances conductivity, prevents oxidation and corrosion, and prolongs the stability of the magnetic circuit.

[0040] The assembly of each component is carried out according to the following process: First, the pressure rod 2 is inserted into the cavity 11 of the coil bracket 1, so that the middle part of the pressure rod 2 passes through the support bar 12, ensuring that the pressure rod 2 can rotate flexibly around the support bar 12; then, the neodymium iron boron magnet 5 is fixed to the groove at the tail end of the pressure rod 2 with epoxy resin glue, and the glue layer thickness is controlled at 0.1-0.2mm; next, the pressure plate 3 is fastened to the front end of the pressure rod 2 with screws; then, the wound coil 4 is put into the outside of the coil bracket 1, and the lead wires at both ends of the coil are soldered to the terminal 41, and the solder joint is wrapped with heat shrink tubing for insulation; finally, the magnetic conductive sheet 6 is installed, and the N pole magnetic conductive sheet 61 and the S pole magnetic conductive sheet 62 are fixed to both sides of the coil bracket 1 with screws respectively.

[0041] At work, such as Figure 5 As shown, when the pressure plate 3 is pressed down, the pressure rod 2 rotates around the support bar 12. The tail end of the pressure rod 2 abuts against the first contact part 611 of the N pole magnetic sheet 61, and the front end of the pressure rod 2 contacts the fourth contact part 622 of the S pole magnetic sheet 62. At this time, the magnetic field lines of the magnet 5 start from the N pole, pass through the first contact part 611 of the N pole magnetic sheet 61, the pressure rod 2, and the fourth contact part 622 of the S pole magnetic sheet 62 in sequence, and return to the S pole of the magnet 5. The coil 4 cuts the magnetic field lines to generate electrical energy.

[0042] like Figure 6 As shown, when the pressure plate 3 is pressed down, the pressure rod 2 rotates in the opposite direction around the support bar 12. The tail end of the pressure rod 2 abuts against the third contact part 621 of the S pole magnetic sheet 62, and the front end of the pressure rod 2 abuts against the second contact part 612 of the N pole magnetic sheet 61. At this time, the magnetic field lines of the magnet 5 start from the N pole, pass through the second contact part 612 of the N pole magnetic sheet 61, the pressure rod 2, and the third contact part 621 of the S pole magnetic sheet 62 in sequence, and return to the S pole of the magnet 5. The coil 4 cuts the magnetic field lines again to generate electrical energy.

[0043] By pressing the pressure plate 3 back and forth, the pressure rod 2 drives the magnetic field line path of the magnet 5 to switch between the contact parts of the two-stage magnetic conductive plates, realizing the two-stage magnetic field line cutting power generation, which effectively improves the power generation efficiency.

[0044] This novel push-button generator, through its reasonable structural design and high-quality material selection, solves many problems of existing push-button generators and has high practical value and market prospects.
