Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings so that those skilled in the art may easily implement the present invention.

First, an apparatus for generating electrical energy from driving of a vehicle according to an exemplary embodiment of the present invention will be described in detail with reference to FIGS. 1 to 3.

1 is a perspective view showing an apparatus for generating electrical energy from driving of a vehicle according to an embodiment of the present invention, Figure 2 is a device for generating electrical energy from driving of a vehicle according to an embodiment of the present invention embedded in the ground Figure 3 is a cross-sectional view showing a cross section of the side, and Figure 3 is a cross-sectional view showing a state that the rotary roll is stepped by the tire of the vehicle according to an embodiment of the present invention.

As shown in Figures 1 to 3, the apparatus for generating electrical energy from the running of the vehicle according to an embodiment of the present invention is a housing 10, a rotating roll 20, the bearing portion 30, the elastic member 40, the support 50, the power generator 60, and the braking member 70.

The housing 10 is embedded in the ground 1 so that the opening 12 of the upper surface is exposed, and is formed of metal or reinforced plastic material sufficient to withstand the load of the vehicle, and needs to be sufficiently large in thickness.

As shown in FIG. 1, the rotating roll 20, the bearing portion 30, the elastic member 40, and the support 50 may be installed inside the housing 10. The large cylindrical space 14 and the bottom 16 are formed.

The rotary roll 20 is disposed inside the housing 10 so as to be in contact with the tire 3 of the vehicle and rotate together by the rotation of the tire 3, and has a rotary shaft 22 at the center in the longitudinal direction. The material of the rotary roll 20 may be made of stainless steel to prevent rust, the length is 400 to 3000mm, the diameter of the cross-section may be formed of a cylinder of 300 to 600mm. The reason should be smaller than the size of the tire to ensure torque. At least a portion of the cylindrical surface of the rotary roll 20 is disposed to protrude out of the opening 12. At this time, at least a portion of the cylindrical surface of the rotary roll 20 may protrude from 100 to 250mm from the upper portion 12. This is such that when the tire 3 of the vehicle passes on the rolling roll 20 and passes, the vehicle 3 runs smoothly so as to be close to the actual road surface without feeling a step as much as possible.

In order for a part of the cylindrical surface of the rotary roll 20 to protrude to the upper portion of the opening 12 so as to contact the tire 3 of the vehicle, the opening 12 has a horizontal length corresponding to the length of the rotary roll 20. 400 to 3200 mm, the width in the vertical direction may be formed to 50 to 250 mm.

Here, the numerical range for the length of the opening 12 is a range for contacting the rotary roll 20 with one or both left and right tires of the left and right tires for large buses and trucks from the general passenger car tire 3. The numerical range for is a range in consideration of the driving safety of the vehicle passing through the rotary roll 20 while a portion of the cylindrical surface of the tire 3 and the rotary roll 20 easily contacted.

As described above, since a part of the cylindrical surface of the rotary roll 20 protrudes from the opening 12 at a predetermined height, the tire 3 of the traveling vehicle steps on the cylindrical surface protruding from the upper portion of the opening 12. When the rotation roll 20 is rotated relative to the rotation shaft 22 in a direction opposite to the rotation direction of the tire 3 of the vehicle, the rotation force is generated.

The rotary shaft 22 installed at the center of the rotary roll 20 is installed inside the housing 10 so as to move freely up and down.

The elastic member 40 which provides elastic force to the pair of bearing members 30 and the bearing members 30 which are movable in both the upper and lower directions on both ends of the rotating shaft 22 so that the rotating shaft 22 can move up and down freely. Is installed.

The bearing portion 30 is for rotatably supporting both ends of the rotating shaft 22, the bearing portion 30 is the bottom 32 and the left and right ends thereof are extended toward the vertical from the bottom 32. It is provided so that it has the side surface 34 and the upper surface 36 in which the shaft coupling hole 36a in which the rotating shaft 22 is seated and coupled is formed in the upper part of the side surface 34. As shown in FIG. In addition, a bearing (not shown) may be installed in the shaft coupling hole 36a to which the rotating shaft 22 is seated and coupled so that the rotating shaft 22 may rotate smoothly.

An elastic member 40 is provided around the lower portion of the bearing portion 30 to provide an elastic force to the bearing portion 30 in the vertical direction.

The elastic member 40 is provided with a hard sponge, rubber, spring, etc., for example, when the rotary roll 20 stepped by the tire 3 of the vehicle moves downward. It plays a role of preventing sudden fall. In addition, when the tire 3 of the vehicle passes on the rotary roll 20, the rotary roll 20 is raised again by the repulsive force of the elastic member 40 to be positioned in place. At this time, even if the rotary roll 20 is moved up and down freely, the unnecessary friction force that prevents the rotation of the rotary roll 20 by placing a space apart from the housing 10 so that the upper end of the cylindrical surface does not contact the opening 12 of the housing 10 It is desirable not to occur. At this time, the pressure for pressing the rotary roll 20 varies according to the size (load) or speed of the vehicle passing over the rotary roll 20. In the case of a large vehicle, the elastic member 40 is compressed a lot because a large load is applied to the rotary roll 20, and in the case of a small vehicle, the pressing member is weakly compressed by a relatively small load. By adjusting the elastic modulus of the elastic member 40 so that the rotary roll 20 is protruded to the opening 12 on the basis of the state that the maximum compression and release of the compression is released to the elastic member 40 by such a large vehicle It is preferable.

The lower portion of the elastic member 40 is provided with a support 50 for supporting the elastic member 40 so that the bearing portion 30 is movable in the vertical direction.

The support part 50 supports the elastic member 40 by the upper side thereof in contact with the lower side of the elastic member 40, and when the elastic member 40 is contracted, the bearing portion 30 is predetermined in the housing 10. Although it is spaced apart from the bearing portion 30 to stop the downward movement at the position of the support portion 30 indirectly supports the bearing portion 30 to move in the vertical direction through the elastic member 40. do.

The lower side of the support 50 may have a rectangular shape or any shape that is fixed to the bottom or sidewall of the housing 10 by bolts and nuts.

The generator 60 is located on at least one side of the housing, the drive shaft 62 is engaged with the rotating shaft 22 to rotate, the generator 64 coupled to one end of the drive shaft 62, the electricity generated from the generator 64 It includes a capacitor 66 that stores. Since the power generation unit 60 is installed near the housing 10, it is preferable that the connection distance is not long to minimize the wasted power. As such, the electricity generated and stored by the power generation unit 60 may continuously supply electricity to a traffic light or a street lamp installed near a road by a power transmission network.

The braking member 70 is coupled to at least one side of the rotary roll 20.

The braking member 70 is for braking the rotation of the rotary roll 20. If the tire 3 of the vehicle stops at the upper portion of the rotary roll 20, the tire 3 of the vehicle that has been stopped is the rotary roll. (20) is in a state of stepping on, and if the rolling roll 20 is not fixed and continues to rotate when the vehicle is going to restart in this state, the tire 3 of the vehicle to be started is rotated by the rolling roll 20. The phenomenon of turning around occurs. Therefore, the braking member 70 is installed to compensate for this problem.

The braking member 70 is coupled to at least one side of the rotary roll 20, and when the rotating shaft 22 is lowered, the braking member 70 is fixed to the upper surface 52 of the support 50 to rotate the rotary roll ( 20) to brake rotation. To this end, the braking member 70 may protrude in the form of a plurality of wing projections 72 having a rectangular or triangular cross section on one side or both sides of the rotary roll 20. The wing protrusions 72 may be disposed in plural on the disc around the rotation shaft 22, and the positions where the wing protrusions 72 are disposed are preferably symmetric about the rotation shaft 22, but are asymmetrical. It may be formed as an enemy.

However, unlike the embodiment of the present invention, the braking member 70 may be omitted if the width of the opening 12 is adjusted so that the tire 3 of the vehicle does not fail due to the rotation roll 20. It is possible.

A method of braking the rotary roll 20 by the braking member 70 will be described with reference to FIG. 4.

4 is a cross-sectional view showing a state in which the rotary roll is braked by the braking member of the apparatus for generating electrical energy from the running of the vehicle according to an embodiment of the present invention.

As shown in FIG. 4, when the tire 3 of the vehicle stops on the upper portion of the rotary roll 20, the rotary roll 20 is lowered, and at least one of the vanes 72a of the brake member 70 is lowered. Which one comes into contact with the support 50.

Even if the wing protrusion 72a does not reach the support 50 properly, the load and rotation of the tire 3 of the vehicle are transmitted to the rotation roll 20 at the same time, so that the rotation roll 20 rotates while the rotation shaft 22 rotates. Descend.

Therefore, when the rotary roll 20 rotates, as well as the wing protrusion 72a which is touching the support part 50 first, the neighboring wing protrusion 72b is brought into contact with the support part 50 together to generate a strong fixing force to generate the rotary roll ( It is possible to brake the rotation of 20).
