Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a conversion device that converts the vibrational energy of a ground vehicle such as an automobile or a train into electrical energy.

[Conventional technology and problems]

Ground vehicles such as automobiles and trains vibrate downward or left and right without stopping their movement, and rapid vibrations generated by the wheels due to uneven road surfaces or rail joints are not directly transmitted to the vehicle body. In order to prevent vibrations from occurring during running, conventional ground vehicles absorb, damp, or convert gentle vibrations using spring-type or fluid-type shock absorbers, dampers, etc. is consumed by the shock absorber or damper without being used in any way.

Such vibrational energy is considered to be quite large considering the weight of the car body, so it is clear that if even a portion of it can be effectively used as electrical energy, it can make a significant contribution to energy consumption. .

This invention was made in view of the above circumstances.
The purpose is to provide an energy conversion device that converts vibrational energy caused by the running of automobiles, trains, etc. into electric energy.

[Means for solving problems]

To solve the above problems, the energy conversion device of the present invention includes a motion conversion mechanism that is attached to a ground vehicle and converts vibrations accompanying the running of the ground vehicle into rotational motion; This motion converter groove is characterized by being equipped with a generator that is rotationally driven by the groove.

[Effect]

In the energy conversion device of the present invention having the above-mentioned configuration, linear vibrations in the vertical or horizontal direction that occur as the ground vehicle travels are absorbed by the one installed on the ground vehicle in accordance with each direction. The motion conversion mechanism converts the motion into rotational motion, which drives the generator to rotate in a predetermined direction and generates electricity. That is, the vibration energy of the ground vehicle is converted into electrical energy. The output of the generator is charged to the batch IJG via the regulator,
It can be used as a power source for lighting, air conditioners, etc., or as an auxiliary power source.

〔Example〕

Hereinafter, two embodiments of the energy conversion device of the present invention will be described with reference to the drawings.

FIG. 1 shows an example of a motion conversion mechanism used in an embodiment of the energy conversion device of the present invention, which is composed of a binion rack device. The rack 1 is fixed, for example, to the axle of an automobile, and the shaft 3 of the binion 2 is rotatably supported by the vehicle body. Therefore, when the vehicle body vibrates, the rack 1 vibrates up and down, and in response, the binion 2 also rotates twice in both directions. As shown in FIG. In other words, if the generator 4 generates power only when the pinion 2 rotates in the direction shown by arrow A, the generator 5 generates power only when the pinion 2 rotates in the direction shown by arrow B. It is designed to generate electricity when it rotates.

FIG. 3 shows another example of a motion conversion mechanism that can be used in the present invention.
4 is rotatably attached. One end of the lever 34 is in contact with the upper surface of the axle 35, and the other end is in contact with the sector gear 3.
6 are fixed integrally. , the car body 31 is fixed to the second sector gear 36! 1.1) A shaft 38 is rotatably attached to the distal end of the other support member 37, and a pinion 39 is engaged therewith. Also, generators are connected to both ends of the shaft 38 of the pinion 39, respectively, as shown in FIG. In this motion conversion mechanism, when the vehicle body 31 and the axle 35 move relative to each other due to vibration, that movement is amplified by the lever 34 and swings the sector gear 36 in the vertical direction, so that the binion 39 engaged with this also reciprocates. The shaft rotates and is connected to the shaft 3EN to drive a generator.

FIGS. 4, 5, 6, and 7 each show an example of a motion conversion mechanism that can be used in the energy-to-energy conversion device of the present invention.

The motion conversion mechanism shown in FIG. 4 (in this case, an inner cylinder 44 fixed to an axle 43 or a part that moves up and down together with the axle 43 is telescopically fitted into an outer cylinder 42 fixed to a vehicle body 41, A screw shaft 45 that engages with the female screw passes through the cylinder 44. The upper end of the screw shaft 45 is rotatably fixed to the vehicle body 41, and a gear 47 is fixed to the lower end. In this mechanism, a compression spring 48 is fitted so as to surround the screw shaft 45. In this mechanism, when the car body 41 and the wheel/sleeve 43 move relative to each other due to vibration, the screw shaft 45 rotates.
Since the teeth 47 reciprocate in both directions, one or more generators may be driven by this.

FIGS. 5a and b) The motion conversion mechanism shown in FIGS.
1, with racks 52 and 53 arranged on both sides of the vehicle, the rack 52 being attached to the vehicle body 54, and the rack 53 being attached to the axle 55 (
Each of these is fixed. As the axle 55 moves up and down relative to the vehicle body 54G, the binion 51 also moves up and down and rotates in both directions (both directions), but this rotation is transmitted to the gear 57 via the flexible joint 56, and the power generation coupled thereto. drive the machine.

The motion converting mechanism shown in FIG. 6 is connected between the vehicle body 61 and the axle 62 and consists of a single cylinder piston. When the axle 62 approaches the vehicle body 61, the sucked fluid is discharged from the discharge roller 4, and the dynamic pressure (...) is generated to drive the generator.
It is also possible to incorporate it into a shock absorber.

The motion conversion mechanism shown in FIG. 7 converts the vibration of the ground vehicle into rotational motion by a connecting rod 71 and a crankshaft 72, and converts the vibration of the ground vehicle into rotational motion by a bevel gear mechanism 73.
It is designed to drive.

In addition, in the embodiment O shown in FIGS. 1 to 6 above,
Although the motion conversion mechanism is disposed between the vehicle body and the axle, it may be attached anywhere as long as it can pick up the vibrations of the vehicle body. However, the motion conversion mechanism that can be used in this invention is not limited to the above (any known mechanism that can convert linear motion into rotational motion can be used as appropriate). .

〔Effect of the invention〕

According to this invention, it becomes possible to effectively utilize the vibration energy that was previously wasted in ground vehicles such as automobiles and trains, making a significant contribution to energy consumption.
