1 to 3, a power generation apparatus 100 according to an embodiment of the present invention includes a vertical movement part 200, a rotation movement part 300, a power generation part 400, and a battery 500.

The up and down motion part 200 is fixedly coupled to the drive shaft 30 connected to the wheel 20 of the vehicle 10 in a vertical direction. The drive shaft 30 is connected to the four wheels 20 of the vehicle 10 and supplies rotational force to the wheels 20 so that the vehicle 10 can travel.

The drive shaft (30) is provided with a drive unit (40) for supplying the rotational force. The driving unit 40 includes a motor that generates electric power by receiving electric energy. The driving unit 40 may be mounted on an electric vehicle or a hybrid vehicle, which has recently been eco-friendly.

Such a vehicle 10 is naturally swung up and down by the bending of the traveling path during traveling. Therefore, a general suspension 10 mounted on the vehicle 10 serves as a buffer to prevent the ride feeling from being lowered by the up and down movement. The suspension device comprises a shock absorber, a coil spring, and a suspension arm on each of the wheels 20. Here, the coil spring acts as a spring so that the up / down movement of the vehicle 10 is not directly transmitted to the driver or the passenger, and the shock absorber prevents the up / down movement of the vehicle 10 through the hydraulic cylinder, It acts as a relaxation stress.

Thus, the up-and-down motion unit 200 is fixedly coupled to the drive shaft 30 in a vertical direction so that the up-and-down motion of the vehicle 10 is transmitted as it is. The up and down motion unit 200 is substantially in the form of a shaft and the first gear structure 210 is formed on the outer circumferential surface thereof.

The rotary motion part 300 has a structure to surround the outer peripheral surface of the up / down motion part 200 where the first gear structure 210 is formed. The second gear structure 310 coupled to the first gear structure 210 is formed on the inner circumferential surface of the rotary part 300 to rotate by the up and down movement of the up and down movement part 200.

Accordingly, the first and second gear structures 210 and 310 may be coupled to each other with a helical structure. In this case, as the up-and-down motion part 200 fixed to the drive shaft 30 moves up and down by the up-and-down motion of the vehicle 10, the turning part 300 rotates naturally. This is because the up-and-down motion part 200 is basically fixed to the drive shaft 30 and does not rotate. In addition, the turning part 300 needs to be installed in a structure in which the up and down positions are fixed to the vehicle 10 so as not to move up and down in a straight line, such as being pulled up and down by the up and down motion part 200 moving up and down.

The power generation apparatus 100 guides the rotation of the rotation unit 300 while blocking the inner space where the first and second gear structures 210 and 310 are coupled to the upper and lower ends of the rotation unit 300, And may further include first and second bearings 600 and 700. Accordingly, it is possible not only to prevent the internal space in which the first and second gear structures 210 and 310 are coupled from being damaged or easily corroded by the external impact, and also to the injury of the maintenance worker, .

At this time, each of the first and second bearings 600 and 700 may have first and second through holes 610 and 710 so that the shaft-shaped up-and-down motion part 200 can pass through the central part. In this case, the inner contact surfaces of the first and second through holes 610 and 710 of each of the first and second bearings 600 and 700 are formed so as not to interfere with the up-and-down linear motion of the up- (needdle) bearing structure.

The inner space blocked from the outside by the first and second bearings 600 and 700 may be filled with the lubricating oil 50. In this case, the frictional force between the first and second gear structures 210 and 310 is reduced through the lubricant 50 to induce the up-and-down movement part 200 to transmit the up-and-down linear motion to the rotation part 300 almost as it is, The force that can be canceled between them can be minimized. That is, the electric energy can be maximally generated from the power generation unit 400 to be described below.

The power generating unit 400 is connected to the turning unit 300. The power generating unit 400 generates electric energy by the rotational motion of the turning unit 300. The principle of generating electrical energy from such rotational motion is based on the principle of electromagnetic induction, which can be easily understood by those skilled in the art. Accordingly, detailed description thereof will be omitted.

The battery 500 is connected to the power generation unit 400. The battery 500 charges electric energy generated from the power generating unit 400. At this time, the battery 500 is configured not to be able to charge only the electric energy generated from the power generating unit 400, but also to be charged through an external electric charging apparatus (not shown).

The battery 500 is connected to a drive unit 40 provided on a drive shaft 30 of the vehicle 10. Accordingly, the driving unit 40 can drive the vehicle 10 through the wheels 20 connected thereto by supplying the electric energy stored in the battery 500 and rotating the driving shaft 30.

The upper and lower moving parts 200 fixedly coupled to the driving shaft 30 connected to the wheels 20 of the vehicle 10 so as to linearly move up and down, A rotation part 300 surrounding the up and down movement part 200 through the coupling of the first and second gear structures 210 and 310 and a power generation part 400 connected to the rotation part 300 to generate electric energy by the rotation Is installed in the vehicle 10, it is possible to generate electric energy from the up / down motion that is naturally generated by the bending of the traveling path that runs on the vehicle 10, very efficiently. Since the electric energy thus generated is generated by simply using up and down shaking naturally occurring in the traveling vehicle 10, a very suitable effect can be anticipated in the eco-friendly aspect that has recently been discussed.

Particularly, when the above components are installed together with the battery 500 that can charge the electric energy to the vehicle 10 that travels by using electric energy such as an electric car or a hybrid vehicle, It has the advantage of being able to use energy more positively.

The power generation unit 400 of the power generation apparatus 100 is connected to an electronic control unit (ECU) 800, which is a unit for controlling the entire electrical apparatuses of the vehicle 10, (800). In this case, the electronic control unit 800 can efficiently control the electric devices of the vehicle 10 using the electric energy generated from the power generation unit 400. At this time, a second battery (not shown) that can charge electric energy generated from the power generator 400 may be separately installed in the electronic controller 800. Alternatively, the electronic control unit 800 may be connected to the battery 500 to receive the electric energy generated from the power generation unit 400 through the battery 500. [

In this way, by supplying the electric energy generated from the power generation section 400 to the electronic control section 800 in addition to the drive section 40 for running the vehicle 10, the power generation apparatus 100 of the present invention is driven by electric energy In addition to an electric vehicle or a hybrid vehicle, it can be installed in any vehicle 10 that uses a fuel engine to efficiently utilize it.

In addition, the upper and lower moving parts 200 and the turning part 300 of the present invention can be provided with a plurality of four wheels 20. In this case, the up and down motion part 200 and the turning part 300, which are coupled with each other with a predetermined stress by the first and second gear structures 210 and 310, Or alleviating the problem, it is possible to replace the existing shock absorber. In other words, when the power generation apparatus 100 of the present invention is installed in the vehicle 10, there is no need to install a shock absorber, so that the effect of reducing the manufacturing cost of the vehicle 10 can be expected.

While the present invention has been described in connection with what is presently considered to be practical and exemplary embodiments, it is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, It will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
