The speed bump self-generating device according to the present invention may be installed on the speed bumps installed on the road 4 to prevent the speed of the vehicle.

The speed bump self-generating device is a footrest unit 10 for generating power by the foot of the vehicle wheel (1), the link unit 20 for transmitting the power generated from the footrest unit 10 to the power generation unit 30 and The power generation unit 30 receives electric power through the link unit 20 to generate electric energy.

The scaffolding portion 10 has a rectangular plate structure having a relatively long length compared to the width thereof, and a rectangular plate is disposed to be long in the width direction of the road 4, and when the wheels of the vehicle pass on the scaffolding portion 10. The footrest portion 10 is pressed by the wheels of the vehicle, and generates a power source in a manner in which the footrest portion 10 is vibrated up and down by the U-shaped steel spring 13.

In other words, the two footrests 10 installed side by side in the direction crossing the road 4 are connected to the U-shaped steel springs 13 so that the stepping force of the vehicle wheel 1 is applied to the two footrests 10. As applied successively, the two scaffolding portions 10 generate a power source by generating up and down vibrations in a manner of alternately floating from the ground.

For example, when the stepping force of the vehicle wheel 1 is applied to any one of the two footrest portions 10, the other one of the two footrest portions 10 is lifted by the elastic restoring force of the steel plate spring 13 Up and down vibration is generated in a manner that is in close contact with the front or rear surface of the vehicle wheel (1) is applying the pedaling force.

The footrest part 10 according to an embodiment of the present invention includes first and

second foothold parts

After stepping on the stepping on the second scaffolding portion 12 will pass.

The steel plate spring 13 is a steel plate having elasticity, and both ends of the U-shaped plate are elongated to form a curved surface with wider ends, wherein the U-shape is applied before the stepping force of the vehicle wheel 1 is applied. The curvature of the plate is smaller than the curvature of the vehicle wheel 1, so that both ends of the U-shaped plate connecting the first and

second scaffold portions

11 and 12 are slightly wider after the stepping force of the vehicle wheel 1 is applied. Minimize vehicle rolling in such a way that the first and

second footrest portions

In addition, the first and second

scaffolding portions

11 and 12 are formed in two pairs at intervals of the front wheel 2 and the rear wheel 3 of the vehicle to step on the two scaffolding portions 10 simultaneously. In this case, when the front wheel 2 of the vehicle presses the second footrest 12, the first footrest 11 pops up and comes into close contact with the rear curved surface of the front wheel 2, and the rear wheel 3 of the vehicle comes into contact with the first wheel. When the footrest 11 is pressed, the second footrest 12 pops up and comes into close contact with the front curved surface of the rear wheel 3, thereby minimizing rattling caused by vertical vibration when the vehicle passes the speed bump, thereby improving the riding comfort. have.

Here, the interval between the first and second scaffolding portions (11, 12) can be adjusted according to the weight of the vehicle, the size of the wheel and the vehicle model, such as passenger cars, commercial vehicles, the first and second scaffolding (11,12) ) Is connected to the U-shaped steel spring (13) to prevent damage to the scaffolding portion 10 even when a large vehicle passes through the passenger car gate.

At this time, in order to minimize the sway of the traffic vehicle and to firmly fix the scaffold 10, the buried fixing frame 24 has a predetermined depth from the ground of the road 4, for example, the thickness of the scaffold 10. By embedding it, the footrest part 10 can be fixed firmly.

The scaffold cover 14 is arranged to be folded or unfolded on the scaffold 10 so as to cover the upper portion of the scaffold 10 so as to protect the scaffold 10 from an external impact such as a vehicle and to reduce the impact of the vehicle. You can prevent the flutter.

The scaffold cover 14 is composed of four plates connected to be continuously contacted via a hinge means such as a hinge, the four plates are each made of a urethane material of the temporary bumps form the vehicle wheel (1) scaffolding cover ( 14) When the foot plate is pushed out by the lowering of the footrest part 10, and when the vehicle wheel 1 is out of the footrest cover 14, the plate is folded back to its original state by the rising of the footrest part 14, thereby preventing the back bump. Form.

The link unit 20 is a member for connecting the scaffolding unit 10 and the power generating unit 30 to transfer the power source of the scaffolding unit 10 to the power generating unit 30, and has a substantially bar shape.

Link portion 20 according to the present invention is typically connected to each one of the scaffold 10, one of the two link portion 20 is the first link (outward) located between the two scaffold (10) ( 21 and the other one of the two link portions 20 are coupled to the end of the first link 21 and the second link 22 positioned inwardly between the two footrest portions 10. It consists of a spherical gear 47 of the fan-shaped to convert the linear movement of the link 21 to the rotational movement.

For example, one end of the first link 21 is connected to the right side of the first scaffolding portion 11 and the left side of the second scaffolding portion 12, respectively, and the other end of the first link 21 is a power generation portion. It is connected to 30, and serves to substantially transmit the up and down vibration of the footrest portion 10 to the power generation portion (30).

In addition, one end of the second link 22 is connected to the left side of the first scaffolding portion 11 and the right side of the second scaffolding portion 12, and the other end of the second link 22 is fixed plate 23. Is connected to the footrest part 10 vibrates in the vertical direction, but serves to hold the movement in the left and right directions.

At this time, the fixing plate 23 is installed on the bottom of the buried fixing frame 24, it is fixed between the first and second scaffolding (11, 12).

One end of the first link 21 is hinged to an outer side of one side of the first footrest 11 and the second footrest 12, respectively, and the other end of the first link 21 is fan-shaped. Is hinged to the end of the spur gear 47 of the first link 21, the first link 21 is diagonally connected between the footrest portion 10 and the power generating portion 30, one end of the first link 21 In the up and down movement of the scaffolding portion 10 is converted into a lateral horizontal movement at the other end of the first link (21).

In addition, one end of the second link 22 is hinged to the inside of one side of the first footrest 11 and the second footrest 12, respectively, and the other end of the second link 22 is fixed plate ( 23 is hinged to each.

The spur gear 47 transmits power to the power generation unit 30 by converting a linear motion (lateral horizontal motion) transmitted from the other end of the first link 21 into a rotational motion by using the principle of the lever. do.

The spur gear 47 has a gear portion 48 having a fan-like flat plate structure, a protrusion 50 formed on the opposite side of the gear portion 48, and a connection between the gear portion 48 and the protrusion 50. Consisting of the hinge portion 49, the projection 50 and the gear portion 48 is rotated in the same direction around the hinge portion 49, the vertical vibration of the link portion 42 to the freewheel of the power generation portion 30 To 33.

Gear teeth are formed at the end of the gear portion 48 in the circumferential direction, and are engaged with the drive gears 33a and 33b of the freewheel 33 and drive the freewheel 33 through the gear teeth.

The protrusion 50 is hinged to the other end of the first link 21 to receive power from the first link 21 to rotate about the hinge 49.

Here, before the stepping force of the traffic vehicle acts on the scaffolding portion 10, the other end portion of the first link 21 and the fan-shaped shape in order to maintain the state in which the first scaffolding portion 11 is always raised to a certain height on the ground. A torsion spring 25 is installed between the protrusions 50 of the spur gear 47.

One end of the torsion spring 25 is fixed to the bottom surface of the spur gear 47, the other end of the torsion spring 25 is fixed to the other end of the first link 21, and the foot force of the vehicle is the footrest part 10. ), The first link 21 is pushed toward the spur gear 47 by the lowering of the footrest portion 10, and the protrusion 50 of the spur gear 47 rotates clockwise to twist the torsion spring 25. When the foot force of the vehicle is released, the protrusion 50 of the spur gear 47 rotates counterclockwise by the elastic restoring force of the torsion spring 25 to move the first link 21 to its original position and thus the footrest part ( 10) is injured.

The power generation unit 30 receives power generated from the scaffolding unit 10 through the first link 21 to generate power.

The power generation unit 30 includes first and second

power generation units

31 and 32 connected to both side surfaces of the first and

second scaffolding units

11 and 12 through the link unit 20, and thus, a traffic vehicle. Each time passes, the power is generated through the first and second

power generation units

31 and 32 to obtain a double power generation effect.

Since the first power generation unit 31 and the second power generation unit 32 are formed in the same configuration only with different positions, the following description of the power generation unit 30 is provided to the first and second

power generation units

31 and 32. I will replace the explanation.

The power generation unit 30 includes a freewheel 33 connected to the scaffold 10 through the spur gear 47 and the first link 21, and an accelerator gear 34 engaged with the freewheel 33. The generator 35 is configured to be engaged with the accelerator gear 34.

The freewheel 33 includes first and second drive gears 33a and 33b coupled to both sides of the spur gear 47 so as to be engaged with the gear portion 48 of the spur gear 47, and the first and second drive gears 33a, And a latch for transmitting the rotational force of 33b) in one direction.

The first driving gear 33a is installed at the upper portion of the freewheel 33 and connected to the first footrest part 10 through the spur gear 47 and the first link 21, and the second driving gear 33b. Is installed at the lower portion of the freewheel 33 and connected to the second scaffolding portion 12 through the spur gear 47 and the first link 21, and the first and second driving gears 33a and 33b are the first. And the power is independently transmitted from the second scaffold (11, 12).

As described above, the first and

second scaffolding portions

11 and 12 do not simultaneously lift, but instead of lifting up, that is, when the first scaffolding portion 11 rises, the second scaffolding portion 12 descends. The vertical vibration is applied to the first and second driving gears (33a, 33b) through the first link 21 and the spur gear 47 in the first and second scaffold portions (11, 12), respectively. The first and second drive gears 33a and 33b rotate in opposite directions when transmitted to each other.

Here, the latch is independently installed in both sides of the freewheel 33 along the circumferential direction and connected to the first and second drive gears 33a and 33b, respectively, and the first and second drive gears 33a and 33b. The rotational force of) is transmitted to the freewheel 33, and the latch is caught by the locking groove inside the freewheel 33 when the locking force is received from each of the driving gears 33a and 33b to rotate in one direction. The rotational force of 33b) is transmitted to the freewheel 33 in one direction, and in the case of rotating in the opposite direction, the rotational force of the first and second driving gears 33a and 33b is reversed. This can prevent interference with each other.

In other words, as the first and

second scaffold portions

11 and 12 are elevated, the first driving gear 33a and the second driving gear 33b rotate in opposite directions, and the first driving gear 33a is rotated. When rotating in the power transmission direction (forward direction), and the second drive gear 33b rotates in the reverse direction, the rotational force of the first drive gear 33a is transmitted to the freewheel 33 through the latch and the second drive gear ( The rotational force of 33b) is not transmitted to the freewheel 33 by the latch, but is lost.

When the drive gears 33a and 33b are rotated in the forward direction as described above, the braces connect the drive gears 33a and 33b to the freewheel 33 to transfer the power by the locking of the freewheel 33, and the drive gears 33a, When 33b) rotates in the reverse direction, the latch stops from the locking groove of the freewheel 33 to disconnect the drive gears 33a and 33b from the freewheel 33 to cut off the power.

The latch is rotatably installed at intervals along the circumferential direction inside the locking groove of the freewheel 33, and the latch is elastically supported in the rotation direction by an elastic member such as a spring and is caught by the locking groove when rotated in the forward direction. When the rotation is made by the idle structure without a lock along the locking groove, power transmission and disconnection between the freewheel 33 and the drive gear (33a, 33b) can be made at the same time.

The freewheel 33 transmits the rotational force of the freewheel 33 to the accelerator gear 34 in such a manner that the freewheel 33 is engaged with the driven gear of the accelerator gear 34 through gear teeth continuously formed circumferentially around its outer circumference. .

The accelerator gear 34 is installed to connect between the freewheel 33 and the generator 35.

In addition, the accelerator gear 34 has a driven gear installed on the same axis on one side thereof, receives power from the freewheel 33 through the engagement between the driven gear and the freewheel 33, the second driven gear and the freewheel It is possible to accelerate the power transmitted from the freewheel 33 through the gear ratio between the 33 and the number of teeth between the driven gear and the accelerator gear 34.

It is connected to the generator 35, and accelerates the rotational movement transmitted from the freewheel 33 to the generator 35, wherein the acceleration gear 34 is to increase the speed of rotation of the freewheel 33 by a predetermined gear ratio Can be.

The generator 35 may use a conventional generator 35, the conductor and the magnet is mounted inside the generator 35 in a conventional structure to generate an electromotive force by the relative movement of the conductor and the magnet according to Faraday's law You can.

For example, the generator 35 generates an electromotive force by the magnet is stopped and the conductor rotates, and the relative rotational movement of the conductor with respect to the stationary magnet.

At this time, the generator 35 has a power generation gear to rotate the conductor, the power generation gear is connected to the accelerator gear 34 to transfer the rotational force from the accelerator gear 34 to the conductor, inducing a rotational movement of the conductor can do.

An idle drum 52 having a structure surrounding the outer periphery of the generator 35 on the concentric circle of the generator 35 is added to the power generation unit 30, but the idle drum 52 is accelerated even if no separate power is applied. It serves to maintain the maximum speed of rotation increased by the gear (34).

11 is a perspective view showing a state in which the idle drum is mounted on the generator according to the present invention.

Hereinafter, a self-powered apparatus using a footrest installed in a place where vehicle traffic is frequent, such as an airport, a port, a terminal, a highway toll gate, and an apartment complex, in particular a speed bump, has a basic function of preventing the speed of the vehicle. Looking at the operation of the features are as follows.

5 is an operational state diagram of the scaffolding unit in FIG. 2, and FIG. 6 is a schematic view showing an operating state when the vehicle steps on the scaffolding unit of FIG. 2.

The footrest part 10 according to the present invention generates the power to move up and down by using the stepping force of the traffic vehicle, and in particular, the two footrest parts 10 installed in the direction crossing the road 4, that is, the first and second footrests By constructing the

parts

11 and 12, the vehicle wheel 1 can be lifted twice in succession each time the user presses once, thereby increasing the amount of power generated and maximizing the power generation effect.

In addition, when the vehicle wheel 1 steps on the first scaffolding portion 11 as the first and

second scaffolding portions

11 and 12 alternately ascend, the other second scaffolding portion 12 or the second scaffolding portion The footrest cover 14 in which the two plates are folded by 12 is held in close contact with the vehicle wheel 1 to hold the wheels, thereby minimizing the rattling of the vehicle, thereby improving the riding comfort.

The first scaffolding portion 11 and the second scaffolding portion 12 are connected to both ends of the U-shaped steel spring 13, respectively, by using the principle of the lever lifting and lifting in the opposite direction, for example, the first As the scaffolding portion 11 rises, the second scaffolding portion 12 descends, and when the first scaffolding portion 11 descends, the second scaffolding portion 12 rises.

Here, the steel plate spring 13 acts as a central axis, and the fixing plate 23 is the first scaffolding portion 11 and the second scaffolding portion through the second link 22 which is installed in both diagonal directions on the side thereof. It is connected to the side of (12) to act to hold the first and second scaffolding portions (11, 12), respectively, so that the first scaffolding portion 11 and the second scaffolding portion (12) can be lifted and operated. .

In addition, the torsion spring 25 installed between the link connected to the first scaffold 11 of the first link 21 and the spur-shaped spur gear 47 is a vehicle or the like during the lifting of the scaffold 10. The first scaffolding portion 11 may always remain injured before the second scaffolding portion 12 as long as the stepping force does not work.

Initially, when the first scaffold 11 is always injured first, the second scaffold 12 is stepped on after the first scaffold 11 is stepped on by the front wheel in the traveling direction of the vehicle. The lifting and lowering operation is performed twice when passing the scaffolding part 10, but when the first scaffolding part 11 is stepped on while the first scaffolding part 11 is first lowered, the vehicle is stepped on the vehicle. The elevating operation is performed once when passing the scaffolding portion 10, and as a result, the amount of power generated by the elevating of the scaffolding portion 10 decreases by that amount, thereby lowering the power generation effect.

Therefore, by mounting the simple torsion spring 25 as described above, when the vehicle wheel 1 passes the scaffold 10, the scaffold 10 that is first stepped on is always kept in an injured state of the scaffold 10. It is possible to increase the amount of power generated by lifting and improve the power generation effect.

In addition, the link portion 20 and the power generating portion 30 are provided on both sides of the scaffolding portion 10, respectively, it is possible to obtain the effect of doubling the amount of power generated by the lifting of the scaffolding portion 10.

The spur gear 47 in the form of a fan in the link portion 20 serves to transfer power as a gear connecting the first link 21 and the power generation unit 30 as well as the scaffolding unit using the principle of the lever. It converts the vertical movement of the (10) to the rotational movement to provide a rotational force to the freewheel (33).

In addition, the spherical spur gear 47 adjusts the linear distance ratio from the central axis of the hinge portion 49 to each gear portion 48 and the protrusion portion 50 to adjust the vertical amplitude generated in the scaffold portion 10. It can be amplified by rotational movement.

In the power generation unit 30, the freewheel 33 receives the rotational force converted from the spur gear 47 through the driving gears 33a and 33b meshed with the spur gear 47. By allowing the rotational force to be transmitted only in one direction, it is possible to receive the rotational force of the driving gears 33a and 33b rotating opposite to each other without interference, and to smoothly rotate the freewheel 33 interlocked with the driving gears 33a and 33b. Can be induced.

If the amplification of the upper and lower amplitudes generated during the lifting of the scaffolding part 10 is also amplified by the spherical spur gear 47, the acceleration gear 34 of the power generation unit 30 is the rotational speed of the rotational motion converted in the vertical motion By increasing the amount of acceleration and rotation with a simple gear ratio, the power generation effect can be improved.

Therefore, according to the above operation by generating the current by using the power of the footrest unit 10 alternately lifting and lowering on the speed bumps on the road (4) can not only reproduce the energy flowing inadvertently in the global high oil price era In addition, by storing this generated current in the charging section and supplying it to the place where power is needed, such as power transmission to the KEPCO or surrounding security, it can contribute to the rapidly increasing demand for electricity and contribute to the national economy.

In addition, by installing the link unit 20 and the power generation unit 30 are installed on both sides of the scaffolding unit 10 so as to be interlocked with the scaffolding unit 10 for lifting and lowering operation, it has a double power generation effect at once, and the link By installing the unit 20 and the power generation unit 30 on the ground, the installation and maintenance work of the device according to the present invention is easy and can be repaired without disturbing the traffic vehicle in case of failure.

In addition, when the first and

second footrests

11 and 12 alternately move up and down, one footrest 10 is applied with a stepping force of the vehicle wheel 1 to another footrest part 10 or footrest cover ( 14) is in close contact with the wheels of the same vehicle to minimize the rattling of the vehicle due to the bumps and bumps can improve the ride comfort.

The spring 45 can vibrate up and down.

At this time, a rubber support 46 is installed at the bottom of one end of the steel plate 45 to induce elastic deformation of the steel plate 45 when the footrest 41 descends, and the foot force is released from the footrest 41. When the steel plate spring 45 can raise the footrest 41 by the elastic restoring force.

The power generation section 43 is composed of the freewheel 33, the accelerator gear 34, and the generator 35 as in the first embodiment, and the vertical vibration of the footrest section 41 in the same operation as in the first embodiment (dynamic Energy) can be converted into electrical energy.

In the second embodiment, the link unit 42 may amplify a small magnitude of the vertical amplitude generated by the scaffolding unit 41 and transmit it to the power generation unit 43 using the same principle as the lever.

For example, an end portion of the link portion 42 is connected to a spur gear 47 having a fan shape, and the flat gear of the fan shape has a gear part 48 having a gear formed on an arc of a predetermined length, and a gear part ( Consisting part 50 formed on the opposite side of the 48 and the hinge portion 49 positioned between the gear portion 48 and the projection portion 50, protruding short distance from the central axis of the hinge portion 49 By converting a short displacement into a large rotational displacement by the distance ratio between the protrusion 50 and the gear portion 48 located at a relatively longer straight line distance, the vertical movement of the scaffold portion 41 is amplified to generate the power generation portion 43. ) Can be delivered.

Here, the accelerator gear 34 installed between the freewheel 33 and the generator 35 can be omitted as necessary, for example, to generate the freewheel 33 without the accelerator gear 34 in order to maximize the power transmission efficiency. Directly connected to the 35 can transmit the power of the scaffolding portion 41 directly to the generator 35.

Therefore, according to the present invention, when the step portion 41 is installed on the stairs 40 so as to be movable, and the stepping force is applied to the step portion 41 when the stairs 40 are moved up and down, the footrest portion ( 41, the up and down vibration is generated, the up and down vibration generated in the staircase 40 is transmitted to the power generation unit 43 through the link portion 42, the electric power generation unit 43 in the up and down vibration (kinetic energy) electric energy Power can be generated by converting to.

In addition, the power generated by the power generation unit 43 may be supplied to the luminaire 44 installed around the staircase 40 to illuminate through the luminaire 44 installed in a specific portion of the staircase 40, Install an luminaire 44, such as an LED, at intervals on the stairs 40 and induce interest by causing the LEDs to glow in different colors or multiple LED lights to appear at the same time or in sequence.
