Description

Power generation system using tire deformation

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a power generation system using a tire deformation that enables a battery to be charged or used as a power source of an electric motor by using a deformation of a tire generated during a vehicle operation, And a rotational motion to change the driving force to a driving force. In particular, by changing only the deformation which is expanded after the tire is compressed during running of the vehicle, the driving force can be efficiently generated without deteriorating the running performance of the vehicle. .

Unlike an internal combustion engine that generates power by consuming fuel such as gasoline, diesel, or LP gas, an electric vehicle (including a hybrid vehicle) receives electric energy from a battery (electric battery) Drive. Such an electric vehicle does not cause pollution such as generation of harmful gas, noise, and dust generated in the internal combustion engine, and thus environmentally friendly.

An electric vehicle (including a hybrid vehicle) has a battery charged with electric energy, and operates using electric energy charged in the battery. When the electric energy charged in the battery is consumed, the battery must be recharged to operate. In the case of a car powered by gasoline, diesel or Elp-gas, gas stations are widely installed to charge the fuel. Therefore, in the case of the internal combustion engine vehicle, the fuel can be easily charged at any time when the fuel is consumed. However, charging stations for charging electrical energy are not widely deployed to date. Therefore, in the case of an electric vehicle, there is a problem that it is difficult to drive when the electric energy of the battery is exhausted during driving.

On the other hand, a large amount of electric energy is required to drive an electric vehicle. However, an electric vehicle can not charge a large amount of electric energy because it has to limit the weight and volume of the battery. A conventional electric vehicle as shown in the following patent document is equipped with a separate system for traveling by using electric energy charged in a battery and for generating electricity by using energy generated during operation and charging the battery through the electric energy I did not. And the amount of electric energy charged in the battery is fixed to a certain limit. Therefore, conventional electric vehicles can not be operated over a long distance.

In addition, the automobile of the internal combustion engine does not require a long time to charge the fuel, and the fuel can be charged immediately. However, in the case of a battery, the greater the amount of electric energy to be charged in the battery, the more time it takes to charge the battery with electric energy. Therefore, there is a problem in commercialization because it requires a lot of time to be charged every time the vehicle is operated.

The present invention has been derived from the problem recognition that fundamentally improves the problems associated with the charging and running of such electric vehicles (including hybrid vehicles) or internal combustion vehicle batteries.

Hereinafter, preferred embodiments of a power generation system using a tire modification according to the present invention will be described in detail with reference to the accompanying drawings. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS In the following description of the present invention, a detailed description of known functions and configurations incorporated herein will be omitted when it may make the subject matter of the present invention rather unclear. Throughout the specification, when an element is referred to as " including " an element, it is understood that the element may include other elements as well, without departing from the other elements unless specifically stated otherwise.

1 to 8, a power generation system using a tire modification according to an embodiment of the present invention includes a driving unit 10 for converting a deformation of a tire 30 into a driving force; And a power generation unit 20 that generates power using the driving force converted by the driving unit 10.

The power generating unit 20 is configured to generate power using the driving force transmitted from the driving unit 10. The power generating unit 20 generates power by using the rotational force transmitted from the rotating unit 130, 220), that is, either the permanent magnet 210 or the coil 220 is rotated to generate an induced electromotive force.

The driving unit 10 is a structure for converting the deformation of the tire 30, which occurs during driving, into a driving force, such as a car (which is a concept involving a passenger traveling with a tire 30 mounted thereon such as a bicycle, a car, to be. The tire 30 of the automobile is repeatedly deformed while traveling. That is, the tire surface, which is in contact with the ground during traveling, is compressed by the weight of the automobile and the like. As a result, the compressed portion of the tire surface is re-inflated by the air pressure inside the tire 30 and restored to its original state, so that the tire 30 repeatedly compresses and expands while driving. In the power generation system of the present invention, the deformation of the tire (30) repeatedly compressing and expanding during the running of the vehicle is converted by the drive unit (10), and the drive unit ) So that it can be used to charge the battery of the internal combustion vehicle, and in particular, the electric car (including the hybrid car) battery (battery).

In particular, the driving unit 10 can change the deformation of the tire 30 due to the compression and expansion of the tire 30 into a reciprocating motion and a rotary motion to change the driving force to a driving force. To this end, the driving unit 10 includes: A spike 110 coupled to the tire 30 and interlocked with the deformation of the tire 30, a rod transmission unit 120 transmitting the motion of the spike 110 to the rotation unit 130, And a rotation unit 130 that rotates in conjunction with movement of the spike 110 transmitted through the transmission unit 120 and transmits a driving force to the power generation unit 20.

The spike 110 is coupled to the tire 30 to interlock with the deformation of the tire 30. 1, the spike 110 has one end coupled to the inner surface of the tire 30 and the other end protruding toward the inner space of the tire 30, And a wire support portion 111 for allowing the wire to be pulled by the spike 110 when the tire 30 is inflated based on the easy turning of the wire. 2, the wire of the rod transmission portion 120 to be described later is fixedly wound on the first winding portion 1312 of the rod interlocking rotation portion 131, which will be described later, and the spike 110 is wound around the first winding portion 1312 The other end of the spike 110 is wound and fixed to the second winding portion of the rod interlocking rotation portion 131. At this time, the wire passing through the spike 110 is easily changed from the wire supporting portion 111 to the spike 110 And the spike 110 pulls the wire from the wire support 111 when the tire 30 expands in an operation process to be described later. The operation process will be described later. The spike 110 coupled to the tire 30 reciprocates in the radial direction of the tire 30 in conjunction with the process of repeated compression and expansion of the tire 30 in accordance with the running of the vehicle. The reciprocating movement of the same spike 110 is transmitted to the rotation unit 130 through the rod transmission unit 120 to be described later.

The rod transmission unit 120 transmits the motion of the spike 110 to a rotation unit 130 to be described later. 1 and 2, the rod transmission unit 120 is connected to the spike 110 and the rotation unit 130 between the spike 110 and a rotation unit 130 to be described later, The movement of the spike 110 reciprocating in the radial direction including the direction of the front, rear, left, and right sides of the tire 30 in conjunction with the process of repeating compression and expansion of the tire 30 is performed as it is to the rotation unit 130 . The rod transmitting portion 120 is preferably in the form of a wire and has one end fixed to one side of the rod interlocking rotation portion 131 to be described later and the other end is connected to the rod interlocking rotation portion 131 through the spike 110, And the specific configuration and operation of the rod transmission unit 120 will be described later.

The rotation unit 130 rotates in conjunction with the motion of the spike 110 transmitted through the rod transmission unit 120 and transmits a driving force to the power generation unit 20. [ That is, the rotation unit 130 converts the motion of the spike 110, which is transmitted through the rod transmission unit 120, into rotational motion to rotate the permanent magnet 210 or the coil 220 of the power generation unit 20 So that power can be generated in the power generator 20.

Meanwhile, in the power generation system according to the present invention, the driving unit 10 can be used for power generation by changing only the deformation of the tire 30 due to expansion after the compression of the tire 30 to a driving force. The reason why the tire 30 is compressed during the running of the vehicle is that the portion of the tire 30 that is in contact with the ground surface of the tire 30 is compressed by the load of the vehicle depending on the traveling direction of the vehicle. There is a problem that the driving performance of the automobile is adversely affected, that is, the automobile needs to consume more energy to achieve the same speed. In the power generation system of the present invention, the tire 30 By changing only the expanded deformation after the compression to the driving force, it is possible to efficiently generate power without deteriorating the running performance of the automobile.

For this, for example, the rotation unit 130 includes a rod interlocking rotation unit 131 coupled to one end of the rod transmission unit 120 and rotated in both directions by interlocking with the rod transmission unit 120, And a rotating gear 132 coupled to the rotating shaft 132. The rotating gear 132 includes a first rotating gear 1321 rotating in conjunction with the rod interlocking rotation part 131, And a second rotating gear 1322 that rotates by receiving the rotating force of the gear 1321. The first rotating gear 1321 is connected to the load transmitting portion 120 in response to the movement of the rod transmitting portion 120 interlocked with the compression of the tire, During rotation of the idle portion 131, the second rotary gear 1322 is not rotated, and when the rod interlocking rotary portion 131 is rotated according to the movement of the rod transmitting portion 120 interlocked with the inflation of the tire, And may rotate together with the second rotary gear 1322. [

The rod interlocking rotation unit 131 is coupled to one end of the rod transmission unit 120 and rotates in both directions in conjunction with the rod transmission unit 120 to rotate the rod transmission unit 120 (more specifically, the spike 110) As shown in FIG. 3 and the like, one end and the other end of the wire of the rod transmission portion 120 are fixed to both sides of the center gear portion 1311 while being wound And may include a first winding portion 1312 and a second winding portion 1313.

At this time, the first winding portion 1312 is wound in a first direction (for example, counterclockwise direction) from one end where the wire of the rod transmission portion 120 is fixed, and also in the second winding portion 1313, (For example, counterclockwise) in the first direction from the other end of the wire rod 120 fixed to the rod, so that when the tire 30 is compressed, the rod interlocking rotation unit 131 always moves in the same direction The wire rod 120 is wound around the wire rod 120 while being rotated in a clockwise direction (for example, in a clockwise direction) So that the interval is narrowed.

6, when the tire 30 is compressed first while being in contact with the ground during the traveling of the vehicle, the spike 110 is first radially (1) The rod interlocking pivot portion 131 is moved in the one direction (for example, clockwise) through the resilient force of the elastic means 1314 to be described later. The distance between the spike 110 and the rod interlocking rotation part 131 in a state in which the wire of the rod transmission part 120 is wound while winding the wire rod 120 wound around the wire rod 120, . 7, when the corresponding portion of the tire 30 is inflated again as the automobile continues to travel, the spike 110 moves toward the outside of the tire 30 in accordance with the inflation of the tire 30 The spike 110 pulls the wire of the rod transfer unit 120 from the wire support unit 111 so that the rod interlocking rotation unit 131 rotates the rod transfer unit 120 The wire is rotated in the other direction (e.g., counterclockwise direction) by the pulling force of the wire 120, and the wire of the rod 120 is unwound to separate the spike 110 and the rod- The elastic means 1314 is compressed in the course of the rotation of the rod interlocking rotation unit 131 in the other direction, as will be described later.

As described above, the rod interlocking rotation unit 131 is provided so that the rod interlocking rotation unit 131 rotates in one direction during the compression of the tire 30 to wind the wire of the rod transmission unit 120 The elastic means 1314 further includes an elastic means 1314 for providing a rotational force. The elastic means 1314 may be a spring-like spring such as a spring as shown in FIG. 5 As shown in FIG. 7, when the tire 30 is inflated, the wire of the rod 120 is compressed in the process of rotating the rod-driven pivot 131 in the other direction When the tire 30 is compressed as shown in FIG. 6, a force for rotating the rod-associated rotary part 131 in a direction (a direction) is provided by using an elastic force to be restored again.

Meanwhile, the rotary gear 132 rotates in conjunction with the rod interlocking rotation part 131. In contrast to the rotation of the rod interlocking rotation part 130 in both directions during the compression and expansion of the tire 30 The rotation gear 132 is capable of transmitting a rotational force to the power generation unit 20 which is always rotated only in the same direction only when the tire 30 is inflated. For example, it includes a first rotating gear 1321 that rotates in conjunction with the rod-associated rotary part 131, and a second rotating gear 1322 that rotates by receiving the rotating force of the first rotating gear 1321, The first rotary gear 1321 does not rotate the second rotary gear 1322 during rotation of the rod interlocking rotary part 131 due to the motion of the rod transmission part 120 interlocked with the compression of the tire, Which is in accordance with the movement of the rod transmitting portion 120 interlocked with the expansion of the rod And the second rotating gear 1322 may be rotated together with the driven gear 131 when the driven gear 131 rotates.

3, the first rotary gear 1321 and the second rotary gear 1322, which are disposed so as to engage with the gear portion 1311 of the rod-associated rotary portion 131, The first rotary gear 1321 and the second rotary gear 1322 are coupled to each other through a coupling structure including a one-way bearing 1323, The second rotary gear 1322 does not rotate, but the second rotary gear 1322 also rotates when the first rotary gear 1321 rotates in the other direction. That is, as shown in FIG. 6, as the tire 30 is compressed, the spike 110 is first advanced toward the center of the tire 30 in the radial direction (① direction) of the tire 30, The first rotary gear 1321 engaged with the gear portion 1311 of the rod interlocking rotation portion 131 is rotated in a direction (for example, a clockwise direction) Accordingly, the second rotary gear 1322 is not rotated by the action of the one-way bearing 1323 in the process of rotating in the other direction (for example, counterclockwise) As shown in the figure, when the automobile continues to travel and the spike 110 is moved backward toward the outside of the tire 30 as the tire 30 is inflated (direction 2), the rod- (In the counterclockwise direction) (b &thetas;), and the rod interlocking pivot portion Way bearing 1323 in the process of rotating the first rotary gear 1321 engaged with the gear portion 1311 of the one-way bearing 131 in one direction (e.g., clockwise) The second rotary gear 1322 also rotates in one direction (for example, clockwise) to transmit the rotational force to the power generator 20. The second rotary gear 1322 transmits the driving force to the power generator 20 while rotating in the same direction only during the movement process in which the tire 30 is always expanded by the action of the one way bearing 1323 In the power generation system of the present invention, only the expansion deformation after the tire 30 is compressed during driving of the vehicle is changed to the driving force, so that the power generation can be efficiently performed without deteriorating the running performance of the vehicle.

3, the first rotating gear 1321 and the second rotating gear 1322 are arranged on the same rotating axis, and the first rotating gear 1321 and the second rotating gear 1322 are arranged on the same rotating axis, By increasing the diameter of the second rotary gear 1322 that receives the rotational force of the first rotary gear 1321 and transmits the driving force to the generator 20 while rotating while receiving the rotational force of the first rotary gear 1321, A structure for increasing the rotational speed of the second rotary gear 1322 can be applied. That is, the second rotary gear 1322, which shares the rotation axis with the first rotary gear 1321, makes one rotation in the same manner in the first rotation of the first rotary gear 1321. At this time, The rotation speed of the outer peripheral surface of the second rotary gear 1322 is increased more than the rotation speed of the outer peripheral surface of the first rotary gear 1321. As a result, The driving force is transmitted at the increased speed to the power generation section 20 which receives the driving force in conjunction with the outer circumferential gear teeth of the second rotary gear 1322. [

On the other hand, the first winding portion 1312 and the second winding portion 1313 of the rod interlocking rotation portion 131 can be moved in the same direction as the spike 110 and the rod interlocking rotation portion 131, The spike 110, the rotation part 130, or the power generation part 20 can be wound around the load transfer part 120, even in an unexpected situation such as a situation where the tire 30 is punctured Thereby making it possible to prevent damage. That is, in case of unexpected situations such as an air pressure of the tire 30 becoming low or a puncture of the tire 30, the pressure of the tire 30 is reduced and the spike 110 is moved toward the inside of the tire 30 As shown in FIG. 8, to move into the rim of the automobile wheel and to be close to the rod interlocking rotation part 131. In this case, the first winding part 1312 and the second winding part If the attachment 1313 no longer winds the wire of the load transfer part 120, the wire of the load transfer part 120 may be unexpectedly damaged in a loosely loosened state or the wire support part 120 of the spike 110 The first winding portion 1312 and the second winding portion 1313 can be wound around the wire as much as possible even in such a situation as described above, So that it always maintains the wires of the load transfer part 120 in an unexpected state even in unexpected situations such as when the tire 30 is punctured, thereby preventing damage to the wires or other structures or system failure .

While the present invention has been described in connection with what is presently considered to be practical exemplary embodiments, it is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, Should be interpreted as belonging to the scope.
