Description

  The present invention relates to a low-energy vehicle capable of accumulating vibration energy that will be wasted when the vehicle is traveling as electric energy and using it as auxiliary energy.

  It is inevitable that oil used as energy for automobiles will eventually be depleted, and that oil consumption has caused global air pollution and global warming, as well as rising oil prices. As a result, the development of next-generation vehicles that solve these problems with low fuel consumption and low pollution is being promoted at a rapid pace.

  Such next-generation vehicles include electric vehicles that are equipped with batteries and that can also be used as household power sources, methanol vehicles that use methanol as fuel, natural gas vehicles that are used in trucks that use natural gas as fuel, engines and Examples thereof include a hybrid vehicle that travels by combining a plurality of power sources or energy sources such as a motor, a fuel cell vehicle equipped with a device that generates electricity by combining liquid hydrogen and coupling with oxygen in the air.

  In any of the above automobiles, low fuel consumption, that is, efficient use of fuel consumption and power consumption is a very important research subject. In particular, when there is no dependence on gasoline or light oil, there is a large limit to the amount of electricity and liquid hydrogen that can be used as an alternative power source, so extreme efforts to reduce energy waste to extend the mileage by a certain amount are made. Has been made. As an example, the energy lost by the brake is stored in the battery, and it is realized as one that is used for traveling energy.

  This is because the braking function of a normal rotary generator is used for braking, and power generation can be obtained by controlling the rotation of the car. Traditionally, exercise has been overlooked.

  In view of the above circumstances, the present invention converts the vibration energy that is wasted during the driving of the automobile into electricity, and uses it auxiliary to driving to improve the efficiency of the driving energy. The problem was to provide a low-energy vehicle that can handle the above.

  In order to solve the above-described problems, the present invention provides a suspension comprising a coil spring and a shock absorber interposed between a tire and a vehicle body in an automobile having a function of running with a motor, and linearly is provided at the upper end of the coil spring. Attach either the stator side or the mover side of the power generator, attach the other end to the lower end, and either the stator side or the mover side is coiled around the iron core, and the other is Permanent magnet or electromagnet, which is formed in a cylindrical shape in which the stator side and the mover side are mutually inserted, and is generated by relative sliding between the stator side and the mover side accompanying the expansion and contraction of the coil spring The present invention provides a low energy vehicle characterized in that electricity is stored in a battery as an auxiliary to drive the motor.

  Since the low-energy vehicle is configured as described above, the stator side and the mover side of the linear power generator move up and down relative to each other when the tire arm and the vehicle body move up and down relatively due to the unevenness of the road surface during traveling. As a linear generator, electricity is generated in the coil, but the magnets are alternately arranged in the N and S poles, and the coils are alternately arranged in the iron core at the corresponding pitch. As a result of this movement, electricity is generated as the movement exceeds the pitch, and the total amount of electric power obtained by adjusting the pitch is obtained, which is accumulated in the battery and supplementarily supplied to the motor for running the automobile. In addition, the movement between the stator side and the mover side is braked as electricity is generated, so that this also functions as a shock absorber.

  The linear power generator (linear generator) is basically the same structure as the linear motor when it is explained that the rotary motor is opened and the movable part is a linear motor that moves linearly. It is a device that can generate electricity by linear motion. Since the vertical vibration of a car is a large energy, a large amount of electric power can be obtained even by capturing minute movements.

  As described above, according to the present invention, although it is a slight reciprocal movement between the tire arm and the vehicle body, the fuel consumption and electric power required for traveling are changed by changing the extremely large and continuous movement to electricity. As a result, it is possible to provide a low-energy vehicle that consumes less energy and is friendly to the global environment.

  Next, embodiments of the present invention will be described with reference to the drawings.

  FIG. 1 and FIG. 2 show an embodiment, and the low energy vehicle has suspensions 3, 3,.. Equipped. The type of vehicle is suitable for a vehicle having a function of running on electric power, such as an electric vehicle, a hybrid vehicle, and a fuel cell vehicle. Because each suspension 3, 3,... Is equipped with linear power generators 5, 5, 5, and 5, after the automobiles are equipped with a battery 6 that stores electricity and a motor (not shown) that is driven by electric power. is there.

  The suspension 3 is an integral type in which a shock absorber 7 and a coil spring 9 are combined (FIG. 2). The shock absorber 7 includes a cylinder 11 and a piston rod 13 inserted into the cylinder 11. A hook-shaped latching portion 15 is provided as a spring receiver, a mount member 17 connected to the vehicle body is provided at the upper end of the piston rod 13, and a coil spring 9 is interposed between the latching portion 15 and the mount member 17. Compressed and intervened.

  In each of the suspensions 3, 3,..., The linear power generator 5 includes a mount member 17 that has a stator side 19 and a latch portion 15 that has a mover side 21. The stator side 19 and the mover side 21 are connected to each other. It is formed in a cylindrical shape that is mutually attached. Although the structure between the stator side 19 and the mover side 21 varies, an electromagnet is used for the stator side 19 and a permanent magnet is used for the mover side 21.

  FIGS. 3 and 4 are presented to explain the principle of the linear power generator 5. On the mover side 21, the N pole and S pole of the strong magnet 26 are alternately opposed to the stator side 19. Are arranged on the opposite side of the stator side 19 in the iron core 22 and the coils 24 are wound around the iron core 22. Due to the mutual movement P with the child side 21, a current flows through the coil 24, which is rectified and supplied to the battery 6.

  As shown in FIG. 1, each suspension 3, 3,... Is attached to the arm as the shaft side of the tire 1 at the lower end of the cylinder 11, and receives the load of the vehicle body by the mount member 17 at the upper end. The vertical vibration between the tire 1 and the vehicle body inside is absorbed by the coil spring 9 and the shock absorber 7. That is, since the hook portion 15 and the mount member 17 expand and contract, current is generated in the coil by the movement P between them, but current is generated between the concave groove 23 and the concave groove 23 for each pitch. A little movement generates a lot of power as a sum.

  In addition, since resistance is generated in the movement P at the same time as electricity is generated in the coil 24, which is braking, the linear power generator 5 may function as an auxiliary to the shock absorber 7 or as an alternative. it can. That is, the shock absorber 7 can be omitted. This is because the shock absorber 7 has a function of controlling repetition of expansion and contraction of the coil spring 9 and can be used instead.

  FIG. 5 shows the case where the shock absorber 7 is independent of the coil spring 9. A base material 28 fixed to the arm 27 is attached to the lower end of the coil spring 9, and the upper end is connected to the vehicle body. A top member 29 is attached, and the coil spring 9 is compressed and interposed between them, and the movable member side 21 is attached to the base member 28, and the stator side 19 is attached to the top member 29. The relationship between them is the same as in the above embodiment.

It is a perspective view of the low energy vehicle which shows the principal part of this invention transparently. It is a longitudinal cross-sectional view of the suspension provided with the linear electric power generating apparatus as the principal part. It is a perspective explanatory view showing a linear power generator in principle. It is sectional explanatory drawing which shows a linear electric power generating device theoretically. It is a longitudinal cross-sectional view of the suspension provided with the linear electric power generator which shows other embodiment.
