Description

The invention relates to electrical machines that do not contain moving or deformable elements, and is used to convert the mechanical energy of human movement into electrical energy, followed by its accumulation and use for the operation of mobile devices.

A technical solution is known - a device and method for storing energy for shoes, in the sole of which there is a coil and a permanent magnet with the possibility of moving it when walking. A rectifier, an electrical energy storage device, a connector for connecting external energy consumers or a device for wireless power transmission are connected to the coil [US 2013020986 Al, H02J 7/00; H05K 13/00 (2006.01), 01/24/2013].

The disadvantage of this device is that the energy efficiency of the generator depends on the acceleration with which the human legs move, and the device stops working if the permanent magnet does not move relative to the solenoid, for example, when walking slowly.

A device is known - a generator, the elements of which also contain permanent magnets and coils located in different mounting blocks on the knees and in the energy storage unit and on a belt or in a pocket. The mounting blocks are connected to the energy storage unit by wires, which provide a movable connection of the device elements with the possibility of attaching or detaching the energy storage unit.

The device is not energy efficient enough, since the location of the mounting blocks on the knees does not provide a high speed of their mutual movement, such as those located in the lower part of the shoe. In addition, the design of the device does not ensure that the turns of the coils get into the areas of the highest magnetic field strength of the permanent magnets, which also reduces the amount of energy generated [KR 20110127334 A, H02J 7/00; H02K 17/42 (2006.01), 11/25/20112].

The closest technical solution is a device that includes a pair of shoes with permanently mounted magnets and coils for generating electrical energy, and a pair of magnet-coil elements are located in different items from a pair of shoes.

The disadvantage lies in the low level of generated energy due to the fact that the design of the device does not provide a guaranteed hit of the turns of the coils in the areas of the highest magnetic field strength of permanent magnets when a person moves [CN 202504336 U].

The technical result consists in increasing the amount of generated energy by ensuring that the turns of the coils are guaranteed to enter the zones of the highest magnetic field strength of permanent magnets when a person moves.

The proposed technical solution is implemented due to permanent magnets, inductors, rectifiers, batteries and connectors for connecting energy consumers located inside a pair of shoes, so that a pair of "permanent magnet-inductor" are located in different items from a pair of shoes. Moreover, the permanent magnets and inductance coils are equipped with magnetic circuits, the poles of which are directed towards the opposite object of a pair of shoes, the axes of the magnetic circuits are inclined at the same angle in absolute value to the horizontal, and the slope angles are different in sign for the magnetic circuits of permanent magnets and magnetic circuits of the inductance coils located in different objects from pairs of shoes.

The claimed electric generator differs from the prototype in that the permanent magnets and inductors are equipped with magnetic circuits, the poles of which are directed towards the opposite object of a pair of shoes, the axes of the magnetic circuits are inclined at the same angle in absolute value to the horizontal, and the tilt angles are different in sign for the magnetic circuits of the permanent magnets and the magnetic circuits of the coils inductance located in different items from a pair of shoes.

The electric generator (Fig. 1) consists of permanent magnets 1, inductors 2, rectifiers 3, batteries 4, connectors for connecting energy consumers 5. Inductors 2 are connected by wires 6 to rectifiers 3, which are connected by wires 6 to batteries 4, which are wires 6 connected to connectors for connecting energy consumers 5. Permanent magnets 1 are equipped with magnetic cores 7, the poles of which are directed towards the opposite object of a pair of shoes. The inductors 2 are also provided with magnetic circuits 8, the poles of which are directed towards the opposite object of a pair of shoes. All elements of the device are fixedly fixed in the sole of each of the items of a pair of shoes 9. The axes of the magnetic cores 7 and 8 are located at the same absolute angle to the horizon α. Moreover, the slope angles α are different in sign for the magnetic circuits 7 of permanent magnets 1 and the magnetic circuits 8 of the inductors 2, located in different items from a pair of shoes. For example, if the angle of inclination α of the axes of the magnetic circuits 7 of permanent magnets 1 in the first object from a pair of shoes is positive, then in the second object of a pair of shoes the angle of inclination α is negative, while the angle of inclination α of the axes of the magnetic circuits 8 of the inductance coils 2 in the first object of a pair of shoes negative, and in the second item from a pair of shoes - positive.

The device works as follows. When walking or running, the soles of the shoes 9 make periodic movements relative to each other. In this case, inductors 2 move in magnetic fields formed by permanent magnets 1 and magnetic circuits 7. The presence of magnetic circuits 7 and 8, as well as their location at angles to the horizon, provides a greater magnetic field strength during the interaction of permanent magnets with inductors and a greater amount of generated electrical energy . The angle of inclination to the horizon is necessary because the relative movement of the objects of a pair of shoes occurs only when one of the objects is on the surface of the earth, and the other is raised to a certain height. With periodic movements of footwear, an alternating eclectic current arises in inductors 2, which is transmitted through wires 6 to rectifiers 3, which convert the current into direct current, and batteries 4 accumulate electrical energy. The accumulated energy can be transferred using the connectors for connecting energy consumers 5 for recharging mobile devices or for other purposes.

The proposed design of the generator provides a more efficient generation of electricity and fast charging of the batteries by increasing the amount of generated energy by ensuring that the turns of the coils get into the zones of the highest magnetic field strength of the permanent magnets when a person moves.
