Description

Technical Field

[0001] The invention relates to the technical field of motors, and in particular to a pulley-type portable energy storage generator. Background Art

[0002] In daily life, people often encounter the problem of insufficient power in their mobile phones or tablets. When they are out, their power banks may run out of power or they may forget to charge them. At this time, not being able to find a stable power source in time will cause a lot of trouble. Even if a stable power source can be found, the charging time required for the power bank is too long, and the amount of power charged by the power bank in a short period of time cannot meet the power needs of the mobile phone or tablet.

[0003] The generator is one of the mechanical devices that converts other forms of energy into electrical energy. It was invented by the famous British scientist Faraday. In 1831, based on his knowledge of electricity, Faraday successfully developed a machine that can generate electric current autonomously, that is, a generator. The generator is driven by a turbine, steam turbine, diesel engine or other power machinery, converting the energy generated by water flow, air flow, fuel combustion or nuclear fission into mechanical energy and transmitting it to the generator, which is then converted into electrical energy by the generator. Unlike power banks, generators do not require a power source to charge them, and they can generate power by themselves. However, the generators currently on the market are relatively large in size, which is not conducive to carrying around, and the easy-to-carry generators are mostly hand-cranked generators, which require manpower to continuously turn the handle, and people's hands cannot be freed, which is inconvenient for daily work and life.

[0004] In summary, there is an urgent need in the art for a portable generator that can free the hands. Summary of the invention

[0005] The purpose of the present invention is to provide a pulley-type portable energy storage generator, which can be carried around and free the hands.

Coils are arranged in grooves opened on the top inner wall and the bottom inner wall of the generator housing, and pulleys are arranged in guide grooves opened on the front inner wall and the back inner wall of the generator housing.

[0040] The length of the spring is 5 mm to 8 mm.

[0041] The pulley-type portable energy storage generator further comprises a pulley rod 9; the pulley 6 and the magnet 4 are connected via the pulley rod 9; and the pulley rod 9 is bonded to the pulley 6 and the magnet 4 respectively.

[0043] The technical solution of the present invention is described below with a specific embodiment:

[0044] The pulley-type portable energy storage generator of the present invention is a generator based on the electromagnetic induction principle of cutting magnetic flux lines, which converts human body movement into electrical energy and stores it in a lithium battery. The generator combines the principle of magnetoelectricity with the charging and discharging principle of the lithium battery 10, and can generate electrical energy by cutting the magnetic flux lines through the relative movement of multiple sets of coils 2 and magnets 4 to generate inertial force continuously generated by people walking or exercising, and collect and store it in the lithium battery 10. When charging, the lithium battery 10 can provide the stored electrical energy to the external device 8 at any time, so the present invention can be used as a power source to charge electronic products such as mobile phones and tablets.

[0045] The pulley-type portable energy storage generator of the present invention is composed of a generator housing 1, a plurality of coils 2, guide rail grooves 3, magnets 4, springs 5, a pulley mechanism, a rectifying, filtering and voltage-stabilizing circuit 7 and a lithium battery 10.

[0046] The pulley mechanism includes a pulley 6 and a pulley rod 9, and the pulley mechanism is composed of an ordinary rod (pulley rod 9) and a wheel (ordinary pulley, i.e., pulley 6). Due to the disturbance, the magnet 4 brings the pulley 6 to reciprocate in the track (guide groove 3), and the pulley 6 can only slide in the guide groove 3 due to the upper and lower restrictions.

[0047] The guide rail groove 3 is a common rectangular groove. The guide rail groove 3 is a groove track for fixing the horizontal position of the magnet 4.

[0048] Multiple groups of coils 2 are fixedly bonded in the inner groove of the generator housing 1 by resin glue. When the magnet 4 moves to generate a changing magnetic field, the multiple groups of coils 2 cut the magnetic flux lines and generate an alternating current. The two inner wall surfaces of the generator housing 1 are provided with guide grooves 3 to provide a track for the movement of the magnet 4 and support the movement of the magnet 4 inside the generator. The magnet 4 can move freely when it is initially disturbed in the device (pulley-type portable energy storage generator), thereby providing a changing magnetic field for the device and providing conditions for the coil to cut the magnetic flux lines. The guide groove 3 is installed in conjunction with the pulley mechanism and can be disassembled (the pulley 6 can be placed into the guide groove 3 from one side of the device, and can be disassembled by taking it out from one side). The magnet 4 and the pulley mechanism are bonded as a whole using resin glue, and the pulley mechanism can make the magnet 4 slide freely along the guide groove 3 in the generator device (pulley-type portable energy storage generator). The magnet 4 and the spring 5 are also bonded together with resin glue. The spring 5 moves with the magnet 4. The spring 5 can provide elastic force for the magnet 4. When the magnet 4 moves to the side wall of the generator housing 1, an elastic restoring force can be generated. When the human body moves, the magnet 4 can move back and forth in the pulley-type portable energy storage generator. The magnet 4, the spring 5 and the pulley mechanism can be bonded as a whole and installed from one side of the generator housing 1.

[0049] The processing technology of the generator housing 1 with guide grooves 3 on the two inner wall surfaces can adopt modeling 3D printing and other methods, and use drawing software to directly print the three-dimensional model into upper and lower or left and right parts, and then assemble the various parts and finally seal them with glue.

[0050] The coil 2 does not need an initial current. The pulley-type portable energy storage generator of the present invention can make multiple sets of coils 2 cut the magnetic flux lines due to the movement of the human body to drive the magnet 4 therein to slide, thereby generating current. The pulley-type portable energy storage generator of the present invention is based on the principle of magnetoelectricity. There is no need to provide an initial current for the coil 2. The initial energy is provided by human movement, or by the movement of the magnet 4 of the pulley-type portable energy storage generator.

[0051] The generator housing 1 is used to support the entire device and bond multiple groups of coils 2. The multiple groups of coils 2 are symmetrically installed in the grooves on the upper and lower sides of the generator housing 1. The coil spacing is 5 to 12 mm, and the size of the pulley-type portable energy storage generator can be flexibly changed. The inner wall of the generator housing 1 is 10 to 15 mm away from the upper and lower surfaces of the magnet 4. The guide grooves 3 on the two inner walls cooperate with the pulley mechanism so that the pulley 6 can slide horizontally along the groove direction in the guide groove 3 to achieve the effect of cutting the magnetic flux lines. The springs 5 ​​on both sides can generate elastic restoring force when the magnet 4 and the pulley mechanism move to the side wall of the generator housing 1, and then reciprocate at both ends. The length of the spring 5 is 5 to 8 mm, which can be adjusted according to the size of the pulley-type portable energy storage generator structure. Multiple groups of coils 2 serve as conductive carriers, and each group of lead wires is connected to the rectifier, filter and voltage regulator circuit 7. The circuit structure of the rectifier, filter and voltage regulator circuit 7 is as shown in Figure 3As shown ( Figure 3 The other structures except the generator housing 1, the lithium battery 10 and the external device 8, namely the structures of the rectifier, filter and voltage regulator circuit 7, include capacitors C1~C4 and diodes D1~D4 and a linear regulator LM7805CT), which store the electric energy generated by the coil 2 cutting the magnetic flux lines in the lithium battery 10, and when the electric energy is stored in the rectifier, filter and voltage regulator circuit 7, it can provide electric energy for the external device 8.

[0052] Figure 3 The rectifier, filter and voltage-stabilizing circuit 7 shown is connected to multiple groups of coils 2 on the generator housing 1, and the generated electric energy is stored in the lithium battery 10. The effect of the rectifier, filter and voltage-stabilizing circuit 7 is that the irregular AC power generated can be converted into a DC power of constant 5V or other magnitude as a whole. The principle is: the function of the rectifier circuit is to use the unidirectional conductivity of the diode to convert the AC power into a unidirectional current or voltage. The bridge rectifier circuit is more commonly used in low-power rectifier circuits, and the present invention also adopts the same; after rectification, the load obtains a unidirectional pulsating voltage, which contains both DC components and AC components such as fundamental waves and harmonics. Therefore, a low-pass filter circuit is generally connected to filter out the AC components. The capacitor in the rectifier, filter and voltage-stabilizing circuit 7 of the present invention plays a filtering role; the DC voltage after rectification and filtering is susceptible to fluctuations and changes in load current, so a stable DC output voltage must be obtained through a voltage-stabilizing circuit.

[0053] As a mature circuit, the rectifier, filter and voltage regulator circuit 7 can convert the irregular AC power into a constant DC power of 5V or other magnitudes. The principle is to convert AC power into DC power through a circuit composed of diodes and capacitors, which is not an improvement of the present invention.

[0054] The invention is based on the fact that the generators currently on the market are relatively large in size, which is not convenient for carrying around, and that the generators that are easy to carry are mostly hand-cranked generators, which are not convenient for daily work and life, and the charging time required for power banks is too long. On this basis, a portable energy storage generator based on electromagnetic induction, namely a pulley-type portable energy storage generator, is proposed, which generates electricity using the vibration generated during walking and stores the electrical energy for emergency use.

[0055] Compared with the prior art, the advantages of the pulley-type portable energy storage generator of the present invention are:

[0056] (1) It can free the hands: the existing power generation device requires manpower to continuously turn the handle, and the hands cannot be freed, while the device of the present invention only requires the person to walk, run, etc.

[0057] (2) Smaller resistance: In the process of converting mechanical energy into electrical energy, a large part of the mechanical energy of the existing power generation device is lost due to overcoming resistance. The magnet, spring, and pulley mechanism combination structure designed in the present invention can reduce resistance through the form of pulley movement.

[0058] (3) Simple structure: The pulley-type portable energy storage generator of the present invention does not need to consider the direction of the generator mechanism. The generator generates a changing magnetic field through the movement of the magnet to achieve the purpose of cutting the magnetic flux lines, and the mechanism of power generation is simple.

[0059] (4) High efficiency in converting electrical energy: Multiple sets of coils can be arranged in the mechanism (structure) designed by the present invention, and the range of cutting magnetic flux lines is larger, which can more efficiently convert mechanical energy into electrical energy.

[0060] (5) The conductive wire in the pulley-type portable energy storage generator of the present invention does not move with the magnet, which can prevent wear and tear, and the device has a long service life.
