Description

WIND-POWERED TRANSPORT DEVICE

The present invention relates to a wind-powered transportation device, and more particularly, to a wind-powered transportation device configured to be placed on a moving object and transmit power generated by wind power to a battery inside the object for use.

As a prior art document similar to the present invention, there is Korean Patent Publication No. 10-2019-0085762 (Self-powered electric bicycle). The prior art document is an invention that seeks to charge a battery while driving an electric motorcycle or electric bicycle by additionally installing a generator on a wheel to which power is transmitted.

The prior art also includes an invention in which a power generation coil is installed inside a wheel and electromagnets are layered in a sandwich format to generate power according to the rotational force of the wheel.

The above prior literature has the following problems.

First, the prior literature states that when the transportation facility moves forward, the wheel with the generator installed also rotates. When the wheel rotates, power generation is possible by the rotational force, but in reality, the structure does not significantly increase energy efficiency. In addition, the prior literature does not provide exact details on which part of the generator rotates together with the wheel rotation. According to the description in the prior literature, the rotating plate can rotate with the wheel by connecting both the coil plate and the electromagnet plate to the shaft, and only the coil plate can rotate, or neither can rotate. Even if the rotating plate with the electromagnet on the shaft is fixed and rotates with the wheel to generate electricity, the transportation facility increases the weight of the generator and the moment of inertia of the wheel. Therefore, in order to rotate the wheel with the generator installed, more energy is required than in order to rotate the wheel without the generator installed. Ultimately, since more electric energy is consumed to rotate the wheel, even if electric energy is generated only by the pure rotational force of the wheel, energy efficiency may not increase significantly, or may even decrease.

In addition, the prior literature can obtain primary electrical energy only through the direct rotation of the wheels of the vehicle. In other words, when the vehicle stops, the rotation of the wheels also stops and the magnetic material inside the generator also stops immediately. Therefore, the generation of electrical energy also stops.

The technical problem to be solved by the present invention is to provide a wind-powered transportation device that generates energy by rotating a generator using wind power, thereby improving the energy efficiency of a transportation means.

Another technical problem to be solved by the present invention is to provide a wind-powered transportation device that can solve the problem of increased wheel weight by rotating a generator and ensure the safety of a transportation device.

Another technical problem to be solved by the present invention is to provide a wind-powered transportation device that can facilitate maintenance and repair and improve user convenience of the transportation device.

Another technical problem to be solved by the present invention is to provide a wind power-powered transportation device, which, when installed on the rotational axis of a wheel of a moving object, firstly, a generator generates power energy by the rotational movement of the wheel, secondly, the generator is further accelerated by wind power to rotate and generate power energy, and thirdly, even when the moving object is stationary, i.e., the wheel stops rotating, the generator can continue to rotate for a certain period of time by means of a bearing connection with the rotational axis of the wheel to generate power energy.

Another technical problem to be solved by the present invention is to provide a wind-powered transportation device that can generate power energy by firstly rotating a generator coupled to a rotating shaft by wind power even when not installed on a wheel of a moving object, and secondly, even when the moving object is stopped, since the rotating shaft to which the generator is coupled and the generator are in a bearing-connected state, the generator can generate power energy while continuing a rotational motion for a certain period of time.

The technical problems to be achieved in the present invention are not limited to the technical problems mentioned above, and other technical problems not mentioned can be clearly understood by a person having ordinary skill in the technical field to which the present invention belongs from the description below.

In order to achieve the above technical task, the present invention relates to a wind power-powered transportation device which is placed on a moving object and transmits power generated by wind power to a battery placed on the object, the wind power-powered transportation device including: a housing; a generator which rotates inside the housing, generates power when rotating, and transmits the generated power to the battery; a plurality of wind pressure transmitting members which are placed inside the housing and are fixedly formed along the outer periphery of the generator; and an air supply member which is placed outside the housing and draws in wind blowing toward the object and transmits it into the interior of the housing, and the wind drawn into the interior of the housing through the air supply member pressurizes the wind pressure transmitting members to rotate the generator.

In addition, the rotation center of the generator is characterized by being connected to a rotation shaft and a bearing.

In addition, the generator is characterized in that it rotates in the same direction as the rotation axis.

In addition, the wind pressure transmitting member is characterized in that it is arranged at a certain interval with an incline toward the direction in which wind is introduced through the air supply unit.

In addition, the air supply unit is characterized by including an air inlet through which wind is introduced; an air pressurization unit connected to the air inlet and formed with a narrow width compared to the air inlet; and an air injection unit connected to the air pressurization unit and communicating with the housing to transmit wind in the direction in which the generator rotates.

The above aspects of the present invention are only some of the preferred embodiments of the present invention, and various embodiments reflecting the technical features of the present invention can be derived and understood by those skilled in the art based on the detailed description of the present invention to be described below.

The present invention described above has the following effects.

First, the present invention can improve the energy efficiency of power and non-powered transportation by generating energy by utilizing wind power through a method of rotating a generator. In particular, unlike the existing generator installation method, the generator and related parts are installed on the rotational axis of the wheel, but rotate separately from the rotation of the rotational axis, but are installed so as to rotate in the same direction as the rotational direction of the wheel, thereby minimizing the energy loss that occurs and increasing the efficiency of electric energy generation.

In addition, even if it is not installed on the rotation axis of the wheel, the generator is installed so that it rotates in accordance with the direction of air inflow on the moving object, and even when the moving object stops, the generator rotates in the same direction as the rotation direction by the law of inertia, thereby minimizing the energy loss that occurs and increasing the efficiency of electric energy generation.

In addition, the present invention can solve the problem of increased weight of wheels by rotating the generator, and ensure the safety of the transportation means.

In addition, the present invention can facilitate maintenance and repair of wheels through generators and related parts installed separately from the wheels. That is, the generators and related parts are installed independently from the wheels and do not affect maintenance and repair work, thereby improving user convenience of the means of transportation.

In addition, the present invention provides an eco-friendly transportation system through a wind-powered generator rotation method, thereby reducing the burden on the environment and promoting the establishment of a sustainable transportation system, thereby increasing the eco-friendliness of transportation means by utilizing renewable energy sources and contributing to the protection of the global environment.

The effects obtainable from the present invention are not limited to the effects mentioned above, and other effects not mentioned will be clearly understood by those skilled in the art to which the present invention pertains from the description below.

First, the core structure of the present invention will be described with reference to FIGS. 10 to 12.

The present invention relates to a wind-powered transportation device that is placed on a moving object and transmits power generated by wind power to a battery placed on the object. Here, the moving object refers to all known objects that move by power or non-power, such as a bicycle, motorcycle, or vehicle, and can be understood to be the same as the transportation means (10) described below.

A wind power-powered transport device comprises a housing (H), a generator (G), a wind pressure transmission member (WP), and an air supply member (WS), and can be placed on an object. Hereinafter, for convenience, the housing (H), generator (G), wind pressure transmission member (WP), and air supply member (WS) are referred to as a 'generator'.

The generator may be placed on the wheel of the object and connected to the wheel rotation axis (115) of the object. The generator may be placed anywhere where wind may be blown in when the object moves. At this time, the wheel rotation axis (115) may rotate or may be fixed without rotating.

Since the generator can generate power by wind pressure alone, it can be coupled to rotate separately from the rotation shaft (115). That is, even if the wheel rotates, it does not rotate together with the wheel, but rather, the rotational power of the wheel is transmitted to the generator, and the generator, more specifically, the generator (G) coupled with the wind pressure transmission member (WP), rotates. In addition, the generator (G) can rotate by the wind pressure transmitted to the wind pressure transmission member (WP). Even if the moving object stops thereafter, the generator (G), which was rotating by the wind pressure, can maintain rotation for a certain period of time by inertial motion. To this end, a ball bearing, etc. can be coupled between the rotation shaft (115) and the generator (G). That is, the rotation center of the generator (G) can be coupled to the rotation shaft (115) by a bearing. In addition, when the generator is placed on the rotation shaft (115) of the wheel, it is preferable to configure the generator (G) to rotate in the same direction as the rotation shaft (115). By rotating in the same direction as the rotation axis (115), the rotational power of the wheel is transmitted and the generator (G) can rotate.

The housing (H) can be configured on the wheel of the object. An existing wheel can also be improved to configure the housing (H) as the wheel itself. The housing (H) can play a role in introducing wind blowing toward the object as the object moves into the inside of the housing (H). The housing (H) can be manufactured from a durable material so as not to be deformed by wind pressure. In addition, it can be manufactured from a corrosion-resistant material so as not to be corroded by moisture. In addition, it can be manufactured through separate additional work to improve durability and corrosion resistance.

A generator (G) combined with a wind pressure transmitting member (WP) can be placed inside the housing (H).

The generator (G) rotates inside the housing (H), generates power when rotating, and can transmit the generated power to a battery placed on the object. The structure of the generator that generates power and the connection configuration with the battery are known technologies, so a detailed description thereof will be omitted.

The wind pressure transmitting member (WP) can be coupled to the outer periphery of the generator (G) rotatably coupled to the rotational axis (115), for example, the rotational axis (115) of the wheel of the object. The wind pressure transmitting member (WP) can rotate the generator (G) through wind introduced into the air supply unit (WS) to be described later. To this end, it is preferable that the housing (H) be created in a structure that surrounds the generator (G) and the wind pressure transmitting member (WP), while being installed so as not to interfere with the rotational motions of the generator (G) and the wind pressure transmitting member (WP). In addition, a gap between the housing (H) and the wind pressure transmitting member (WP) can be set so that wind is transmitted to the wind pressure transmitting member (WP) above a certain pressure.

At least a plurality of wind pressure transfer pieces (WP) can be coupled to the outer periphery of the generator (G). The wind pressure transfer pieces (WP) can be arranged in a direction perpendicular to the center of the rotation axis (115). In addition, the wind pressure transfer pieces (WP) can be arranged at a certain interval with an incline toward the direction in which wind is introduced through the air supply unit (WS).

That is, the wind pressure transmitting members (WP) can be arranged at regular intervals based on the direction of the wind flowing in from the air supply unit (WS). The wind pressure transmitting members (WP) can receive the wind and rotate the power generator (G). The wind pressure transmitting members (WP) can be arranged at regular intervals perpendicular to the direction in which the wind flows in, or can be arranged at an angle toward the direction in which the wind flows in. By configuring it in this way, the power generator can efficiently receive the wind and rotate the power generator (G).

The air supply unit (WS) is arranged outside the housing (H) and can draw in wind blowing toward the object and transmit it into the inside of the housing (H). The wind drawn into the inside of the housing (H) through the air supply unit (WS) can pressurize the wind pressure transmitting member (WP) to rotate the generator (G).

For this purpose, the air supply unit (WS) can be connected to the housing (H). The air supply unit (WS) can be formed integrally with the housing (H), or can be formed separately and then joined to each other. In order to transmit the wind introduced through the air supply unit (WS) into the interior of the housing (H), an inlet hole (H_1) communicating with the air supply unit (WS) can be formed in the housing (H) connected to the air supply unit (WS).

The air supply unit (WS) can pressurize the wind introduced by the movement of the object and transmit it to the inside of the housing (H). To this end, the air supply unit (WS) can be configured to include an air inlet unit (WS_1), an air pressurization unit (WS_2), and an air injection unit (WS_3).

The air inlet (WS_1) can collect the wind blowing toward the target object as the target object moves and introduce it into the inside of the air supply unit (WS).

The air inlet (WS_1) is located outside the housing (H) and mainly consists of a passage through which wind flows in, and wind can flow into the air supply (WS) through this point.

The air inlet (WS_1) is the point where wind flows into the air supply (WS) and can be designed for efficient wind inflow.

For example, the inlet of the air inlet (WS_1) can be designed so that wind can freely flow in. To this end, it can have a wide inlet and be designed in a curved shape to improve the flow of wind.

In addition, a direction control device may be used to control the flow of wind and direct it in a desired direction. This device can be configured to guide the flow of wind directionally so that it can be efficiently directed into the air pressurization unit (WS_2).

For example, the direction of wind flow can be controlled by adjusting the angle of the fan blade. This allows the wind to be configured to flow in a specific direction. That is, this direction can be controlled by adjusting the angle at which the fan blade rotates.

In addition, the rotary flow guide can induce the flow of wind and direct it in a desired direction. The rotary flow guide can adjust the flow of wind by rotating or moving, thereby directing the wind in a specific direction.

Additionally, the flow of wind can be controlled by adjusting the positions of the intake and exhaust ports. By positioning the intake port in a certain direction and the exhaust port in the opposite direction, the wind can be directed in the desired direction.

Additionally, directional flaps can be used to control the flow of wind and direct it in a desired direction. The flaps are designed with an adjustable structure, making it easy to control the direction of the wind flow.

The air inlet (WS_1) may include a filtering system to prevent particles such as dust or foreign substances from being introduced. This allows only pure air to be introduced, and solves problems such as malfunctions and reduced efficiency caused by dust or foreign substances.

The air inlet section (WS_1) is designed with a structure optimized for fluidic flow for efficient inflow of wind, thereby minimizing wind loss and allowing the maximum amount of wind to be delivered to the air pressurization section (WS_2).

The wind introduced into the air inlet (WS_1) can be pressurized as it flows through the narrowly formed air pressurization section (WS_2). In this section, the wind pressure can be increased and the conditions for rotating the power generator (G) can be created by pressurizing the wind pressure transfer section (WP).

The air pressurization unit (WS_2) is configured to perform the role of increasing the pressure of the wind to rotate the generator (G) and can be configured in various ways.

First, the air pressurization unit (WS_2) can increase the pressure of the wind by using a rotary fan or propeller. The fan or propeller can increase the pressure by rotating the wind, thereby providing the power necessary to rotate the generator (G).

In addition, the air pressurization unit (WS_2) may include a rotation direction control device to control the flow of wind and effectively transmit it to the generator (G). This device can induce efficient rotation by directing the flow of wind in the direction in which the generator (G) rotates.

Additionally, the air pressurization unit (WS_2) may include a pressurization and compression device for increasing the pressure of the wind and transmitting it to the generator (G). This device compresses the wind to provide a pressurizing force to the generator (G), thereby increasing the power required to rotate the generator (G).

In addition, as described above, it is possible to design structurally to effectively increase the wind pressure without constructing a separate structure for increasing the wind pressure. That is, it can be designed as illustrated using Bernoulli's theorem and the Venturi Tube principle. Referring to FIG. 10, a housing (H) formed in a circular shape is used so that the upper part is formed in a horizontal direction, one end on the left is open to form an air inlet (WS_1), and the other end on the right is closed in a form that surrounds the inlet hole (H_1) of the housing (H). This structure is a structure in which a large amount of wind is introduced into the air inlet (WS_1), and the introduced wind passes through the narrow width of the air pressurization portion (WS_2) and then, in a pressurized state, is introduced into the housing (H) through the air injection portion (WS_3) to rotate the generator (G).

The air inlet (WS_3) is connected to the housing (H) and can transmit wind in the direction in which the generator (G) rotates. That is, as illustrated, the wind pressurized through the air pressurization unit (WS_2) flows into the inlet hole (H_1) through the air inlet (WS_3), and the inlet hole (H_1) can be formed to introduce wind in the direction in which the generator (G) rotates. The inlet of the inlet hole (H_1) can be configured in a curved shape so that the wind can flow in smoothly.

In addition, the air injection unit (WS_3) may include a rotation direction control device to induce the flow of wind in the direction in which the generator (G) rotates within the housing (H). The rotation direction control device may control the flow of wind to introduce wind in a direction optimized for the rotation direction of the generator (G).

Additionally, the air injection unit (WS_3) may include a wind distribution structure to uniformly rotate the generator (G) around it. This allows the wind to be uniformly distributed around the generator (G) to maximize rotational power.

In addition, since wind pressure is required to rotate the generator (G), the air injection unit (WS_3) may include a pressurizing device that pressurizes the generator (G). This device can increase the wind pressure to provide the power required to rotate the generator (G).

An air supply unit (WS) of this type can effectively introduce wind into the housing (H) and provide the pressure and path necessary to rotate the generator (G).

The generator may be installed elsewhere on the object other than the wheel's rotation axis (115).

If the power generator is installed in a different location, it can be installed on a separate rotation shaft (not shown). The power generator can be placed on the separate rotation shaft. At this time, the power generator (G) combined with the wind pressure transmitting member (WP) and the housing (H) enclosing them can be installed anywhere inside or outside the object, and it is preferable that the air supply unit (WS) that introduces wind into the housing (H) be placed in a location where it can introduce wind blowing toward the object due to the movement of the object. Here, if the air inlet unit (WS_1) is of a type that can introduce wind, the air supply unit (WS) can be placed anywhere. In addition, if the air supply unit (WS) and the housing (H) are connected so that the wind introduced into the air supply unit (WS) can be transmitted into the inside of the housing (H), it is preferable that there are no restrictions on the placement location and structure.

In addition, in order to transmit the rotational power of the wheel to the rotational power of the generator (G), the separate rotational shaft may be configured to rotate in conjunction with the rotating wheel. In the case of coupled rotation, the rotational direction may be configured to rotate in either the forward or reverse direction, but it is preferable that the wind introduced through the air supply unit (WS) be configured to pressurize the wind pressure transfer member (WP) in the direction in which the generator (G) rotates.

Hereinafter, some embodiments of the present invention will be described. Since names and the like may be changed for detailed configuration description, reference should be made to the drawing numbers.

A vehicle (10) according to some embodiments is a vehicle including a first wheel and a second wheel, wherein the first wheel can receive energy from a power supply unit (400). The second wheel can rotate by frictional force with the ground without receiving energy from the power supply unit (400). When the first and second wheels come into contact with the ground, the first wheel can receive energy from the power supply unit (400) to generate first rotational kinetic energy. The vehicle (10) can move in a straight line using the first rotational kinetic energy of the first wheel. When the vehicle moves in a straight line, the second wheel can generate second rotational kinetic energy using frictional force with the ground. The second wheel can generate primary electric energy through the second rotational kinetic energy of the second wheel. In addition, even if the vehicle (10) reduces its speed at any moment (or moment by moment) while moving in a straight line, the generator can continue to maintain the original rotational speed through the acceleration force that has already occurred, thereby further increasing the efficiency of the primary electric energy. In addition, even if the second wheel stops completely while moving in a straight line, the generator can continue to rotate due to the acceleration force that has already occurred, thereby generating secondary electrical energy.

In some embodiments, when the vehicle (10) moves in a straight line after receiving energy from the power providing unit (400), a fast air flow may be generated that is pushed backwards by the vehicle (10). The air flow generated at this time is sent into an air pressure vessel installed outside the generator of the second wheel, and the air pressure vessel amplifies and converts the incoming air into faster air and sends it inside the generator, where it is combined with the magnetic bodies (114_1, 114_2) inside the generator and rotates the central rotating plate (114) having the plate (114_3) to generate tertiary electric energy. Therefore, through the present invention, the vehicle (10) can generate primary electric energy, secondary electric energy, and tertiary electric energy through the straight line movement, thereby supplementing the power energy used for the straight line movement.

In some embodiments, the first wheel may include a power drive unit (210) that directly receives kinetic energy from the power supply unit (400), and the second wheel may not include a power drive unit (210).

In some embodiments, when the first and second wheels are in contact with the ground, if the first wheel rotates, the second wheel may also rotate, and when either the first or second wheel is in contact with the ground, if the first wheel rotates, the second wheel may not rotate.

In some embodiments, when the second wheel rotates, the wheel wheel (121) coupled to the rotation shaft (115) and the fixed first and second rotation plates (113_1, 113_2) rotate, the fixed plates (111_1, 111_2) do not rotate, the interlocking rotation gear device (116) and the central rotation plate (114) rotate, and when the central rotation plate (114) rotates, the magnetic body (114_1, 114_2) can rotate together with the central rotation plate (114).

In some embodiments, a central rotating plate (114) coupled with a linkage rotating gear device (116) and magnetic bodies (114_1, 114_2) may be coupled to the rotational axis (115) of the second wheel. The magnetic bodies (114_1, 114_2) coupled with the central rotating plate (114) may be positioned centrally between the first coil body (112_1) coupled with the first fixed plate and the second coil body (112_2) coupled with the second fixed plate (111_1, 111_2). The first fixed plate (111_1) and the second fixed plate (111_2) may be coupled to the rotational axis (115) by a rotating plate connecting ring (110_1, 110_2). The first fixed plate (111_1) may be composed of a first directional electromagnetic band (111_3) and a first coil body (112_1), and the second fixed plate (111_2) may be composed of a second directional electromagnetic band (111_4) and a second coil body (112_2).

In some embodiments, when the first and second wheels are in contact with the ground and the first wheel rotates, the second wheel rotates due to friction with the ground, and as the second wheel rotates, a magnetic field may be generated between the first and second coil bodies (112_1, 112_2) and the first and second magnetic bodies (114_1, 114_2). The electric energy generated at this time may be provided to the battery unit (300).

Specific details of other embodiments will be described in detail with reference to the drawings.

Figure 1 is a conceptual diagram of the configuration of a transportation means, which is an object according to one embodiment of the wind power-powered transportation device of the present invention.

Referring to FIG. 1, a vehicle (10) according to some embodiments of the present invention may include a non-powered wheel (100), a power wheel (200), a battery unit (300), a power providing unit (400), and a power control unit (500).

The non-powered wheel (100) may include a non-powered generator (110), and the powered wheel (200) may include a power drive unit (210). The non-powered generator (110) may be included only in the non-powered wheel (100), and the power drive unit (210) may be included only in the powered wheel (200). In other words, the non-powered wheel (100) may not include a power drive unit (210), and the powered wheel (200) may not include a non-powered generator (110).

A non-powered wheel (100) may be a wheel to which power (or energy) generated by a means of transportation (10) is not directly transmitted. In other words, the non-powered wheel (100) may not directly receive driving power from a power providing unit (400).

The non-powered wheel (100) can generate second kinetic energy by using the first kinetic energy of the vehicle (10). For example, the first kinetic energy can be linear kinetic energy and the second kinetic energy can be rotational kinetic energy. In other words, when the vehicle (10) performs linear motion, the non-powered wheel (100) in contact with the ground can perform rotational motion due to frictional force with the ground.

That is, the non-powered wheel (100) can perform rotational motion only when it is in contact with the ground and the moving means (10) performs linear motion.

When the non-powered wheel (100) performs a rotational motion, the non-powered generator (110) included in the non-powered wheel (100) can generate a plurality of electric energies by the rotational motion of the vehicle (10). Here, if the plurality of electric energies generated by the non-powered generator (110) described above are divided by technology, first; when the vehicle (10) performs a linear motion, the non-powered generator (110) can generate primary electric energy, and also, even if the vehicle (10) stops at some point while performing a linear motion, the original rotational motion continues due to the acceleration force, so that more primary electric energy can be generated. Second; even if the vehicle (10) stops while performing a linear motion, the non-powered generator (110) can continuously generate secondary electric energy in conjunction. Third; tertiary electric energy can also be generated through the flow of air (wind power) generated by the rotational kinetic energy generated by the linear motion of the vehicle (10).

The power wheel (200) may be connected to the power providing unit (400). The power wheel (200) may receive the third kinetic energy generated by the vehicle (10) through the power driving unit (210). In other words, the power wheel (200) may receive the third kinetic energy from the power providing unit (400) of the vehicle (10). The power wheel (200) may generate the fourth kinetic energy by using the third kinetic energy provided from the power providing unit (400). For example, the third kinetic energy and the fourth kinetic energy may be rotational kinetic energy. In other words, the power driving unit (210) may cause the power wheel (200) to rotate by using the third kinetic energy provided from the power providing unit (400). When the power wheel (200) comes into contact with the ground, the vehicle (10) may generate the first kinetic energy by using the fourth kinetic energy of the power wheel (200). The non-powered wheel rotates when the power wheel (200) comes into contact with the ground and rotates, and as it rotates, the vehicle (10) can perform linear motion. At this time, the non-powered wheel (100) is connected to the battery unit (300), and the electric energy generated in the non-powered wheel (100) can be provided to the battery unit (300).

As a result, when both the non-powered wheel (100) and the power wheel (200) are in contact with the ground, when the power wheel (200) starts rotating, the non-powered wheel (100) can also rotate.

However, if either the non-powered wheel (100) or the powered wheel (200) does not contact the ground, the non-powered wheel (100) may not rotate even if the powered wheel (200) rotates. That is, the non-powered wheel (100) may be, as the term suggests, a wheel to which power is not directly supplied.

The battery unit (300) can be connected to the non-powered wheel (100). In addition, the battery unit (300) can be connected to the power providing unit (400). The battery unit (300) can store electric energy. For example, the battery unit (300) can receive electric energy from the outside and store it. As another example, the battery unit (300) can receive electric energy generated from the non-powered wheel (100) and store it. The battery unit (300) can provide the stored electric energy to the power providing unit (400).

The power providing unit (400) is connected to the battery unit (300) and can be connected to the power wheel (200). The power providing unit (400) can receive electric energy from the battery unit (300). The power providing unit (400) can generate third kinetic energy using the electric energy provided from the battery unit (300). The third kinetic energy generated by the power providing unit (400) can be provided to the power wheel (200). For example, the power providing unit (400) can include a motor. The power providing unit (400) supplies electric energy provided from the battery unit (300) to the motor, and the motor can generate third kinetic energy (rotational kinetic energy) using the electric energy. The third kinetic energy generated by the motor can be provided to the power wheel (200) through the power driving unit (210). The power driving unit (210) can include, for example, a driving gear that transmits rotational power to the power wheel (200).

The power control unit (500) can be connected to the battery unit (300) and the power supply unit (400). The power control unit (500) can receive specific information from the battery unit (300) and the power supply unit (400). For example, the power control unit (500) can receive information on the total amount of stored electric energy from the battery unit (300) and control it to be displayed on a display (not shown). As another example, the power control unit (500) can receive information on the rotation speed from the power supply unit (400) and control it to be displayed as is on a display (not shown) or to be converted into the speed of the transportation means (10) and control it to be displayed on a display (not shown).

The power control unit (500) can control the battery unit (300) and the power supply unit (400). The power control unit (500) can control the battery unit (300) and the power supply unit (400) according to the operation signal to provide third kinetic energy to the power wheel (200), thereby operating the vehicle (10). The operation signal may be a signal provided by a passenger of the vehicle (10) (for example, an accelerator operation signal), but the embodiments are not limited thereto.

In summary, when the power control unit (500) receives an operation signal, it can control the power supply unit (400) to provide electric energy stored in the battery unit (300). The power control unit (500) can control the power supply unit (400) to generate third kinetic energy using the electric energy. The power supply unit (400) can provide the generated third kinetic energy to the power wheel (200) through the power drive unit (210). The power wheel (200) can generate fourth kinetic energy using the third kinetic energy provided from the power supply unit (400). The transportation means (10) can generate first kinetic energy using the fourth kinetic energy generated by the power wheel (200). In other words, due to frictional force between the power wheel (200) and the ground, the transportation means (10) can convert the fourth kinetic energy into first kinetic energy.

The first kinetic energy of the vehicle (10) can be provided to the non-powered wheel (100) due to the frictional force between the non-powered wheel (100) and the ground. The non-powered wheel (100) obtains the second kinetic energy by using the first kinetic energy of the vehicle (10), and the vehicle (10) can generate electric energy in a number of ways by using the second kinetic energy. A detailed description will be given later.

Figure 2 is an example of the state of use of a means of transportation to which the wind power-powered transportation device of the present invention is applied.

Referring to FIGS. 1 and 2, a vehicle (10) according to some embodiments may be an electric bicycle. The vehicle (10) may include a non-powered wheel (100) and a power wheel (200). Although not specifically shown, the vehicle (10) may include a battery unit (300), a power supply unit (400), and a power control unit (500) described in FIG. 1.

The non-powered wheel (100) may include a non-powered generator (110). The non-powered generator (110) may only be included in the non-powered wheel (100). In other words, the non-powered generator (110) may not be included in the power wheel (200). The non-powered generator (110) may generate electrical energy through linear motion via the second kinetic energy of the non-powered wheel (100). For a description of the specific mechanical structure and principles, refer to FIGS. 3 to 10.

Referring to FIGS. 1 and 3 to 10, it can be seen that all components of the non-powered generator (110) are fixed around the rotation axis (1156).

A first fixed plate (111_1) and a second fixed plate (111_2) are fixed to the rotation axis (115) and spaced apart in the (y) direction with the rotation axis (115) as the center.

A linkage rotation gear device (116) is fixed at the center of the rotation shaft (115), and a central rotation plate (114) is fixed at the center.

In addition, a first rotation plate (113_1) and a second rotation plate (113_2) are fixed to the rotation axis (115) and are also connected to a wheel (121).

Again, let's break it down into specifics by configuration:

The first rotary plate (113_1) and the second rotary plate (113_2) can rotate together about the rotation axis (115). At this time, a first rotary plate connecting ring (110_1) and a second rotary plate connecting ring (110_2) may be additionally provided to connect the rotation axis (115) and the first rotary plate (113_1) and the second rotary plate (113_2). The first rotary plate (113_1) and the second rotary plate (113_2) can rotate in synchronization with the rotation of the non-powered wheel (100). In other words, when the non-powered wheel (100) rotates, the first rotary plate (113_1) and the second rotary plate (113_2) can also rotate together.

The first fixed plate (111_1) and the second fixed plate (111_2) coupled to the rotation axis (115) can extend in the (X) direction. The first fixed plate (111_1) and the second fixed plate (111_2) can be spaced apart from each other in the first direction and the second direction with the rotation axis (115) as the center.

The first fixed plate (111_1) can be fixed in direct contact with the rotation shaft (115) by a bearing (117) inserted into the first fixed plate bearing case (116_1), and the second fixed plate (111_2) can be fixed in direct contact with the rotation shaft (115) by a bearing (117) inserted into the second fixed plate bearing case (116_2). The first fixed plate (111_1) and the second fixed plate (111_2) can be fixed to the rotation shaft (115) regardless of whether the non-powered wheel (100) rotates. A first directional electromagnetic band (111_3) and a first coil body (112_1) can be connected to one side of the first fixed plate (111_1). A second directional electromagnetic band (111_4) and a second coil body (112_2) can be connected to one side of the second fixed plate (111_2).

An air compression tank (118) can be connected to the outer ends of the first fixed plate (113_1) and the second fixed plate (113_2).

The air pressure tank (118) is an air inlet passage. When the transport device moves in a straight line, an air flow (wind force) is generated around the transport device and is pushed behind the transport device. As the air pressure around the air pressure tank (118) decreases, the surrounding air is sucked into the air pressure tank (118). The air that enters the air pressure tank (118) is sent to the plate (114_3) inside the non-power generator (110) through a small air discharge port inside the air pressure tank (118), causing the central rotating plate (114) to rotate, and the first magnetic body (114_1) and the second magnetic body (114_2) that are coupled together also rotate. This is an application of the Bernoulli Principle and the Venturi Tube.

When the non-powered wheel (100) rotates, the first fixed plate (111_1) and the second fixed plate (111_2) are fixed to the rotation shaft (115) by bearings (117) inserted into the first fixed plate bearing case (119-1) and the second fixed plate bearing case (119_2), but do not rotate, and only the first rotary plate (113_1) and the second rotary plate (113_2) fixed to the rotation shaft (115) by the first rotary plate connecting ring (110_1) and the second rotary plate connecting ring (110_2) can rotate. According to some embodiments, the first rotary plate (113_1) and the second rotary plate (113_2) may also be connected to the wheel wheel (121) and rotate together.

A linkage rotation gear device (116) is coupled to the rotation shaft (115), and a central rotation plate (114) is connected to the linkage rotation gear device (116), and a first magnetic body (114_1) and a second magnetic body (114_2) are coupled front and back around the central rotation plate, and a plate (114_3), which is a wind blade, is fixed to the outer end of the central rotation plate (114).

Referring to FIGS. 6 to 9, the linkage rotation gear device (116) will be described.

The rod brake support frame (116_2) connected to the rotating shaft (115) has a number of grooves, and the rod brake (116_3) is fixed in the grooves by a spring (116_5). One side of the one-way gear (116_1) is perpendicular so that the rod brake (116-3) cannot pass over the perpendicular side and thus cannot rotate, and one side has a gently slanted structure so that the rod brake (116_3) can pass over it, thereby allowing the one-way gear (116_1) to rotate on the gently slanted side. In addition, a gear device bearing (116_4) may be included between the rod brake support frame (116_2) and the one-way gear (116_1) to ensure smooth rotation of the one-way gear (116_1).

If the gear mechanism (116) is rearranged, when the wheel (120) rotates in the S direction, the rotation shaft (115), the rod brake support frame (116_2), and the rod brake (116_3) also rotate together. At this time, the right-angled surface of the one-way toothed gear (116_1) is caught by the rod brake (116_3), and the one-way toothed gear (116_1) also rotates in the S direction. At this time, when the rotation of the wheel (120) stops, the rotation shaft (115) and the rod brake support frame (116_2) also stop. At this time, a force (acceleration force) is generated in the one-way toothed gear (116_1) to continue to rotate in the S direction. This acceleration force pushes the rod brake (116_3) along the inclined surface of the one-way toothed gear (116_1), and the rod brake (116_3) falls over along the inclined surface. At this time, the one-way toothed gear (116_1) rotates in the S direction (the rotational direction in which acceleration is generated). When the one-way toothed gear (116_1) goes over the rod brake (116_3), the rod brake (116_3) is restored to its original position due to the fixed spring (116_5). In this way, the rod brake (116_3) repeatedly falls along the inclined surface of the one-way toothed gear (116_1) and is repeatedly restored to its original position, so that the one-way toothed gear (116-1) can continuously rotate in the designated S direction.

A first magnetic body (114_1) and a second magnetic body (114_2) are fixed to the central rotating plate (114), and a plate (116), which is a wind blade, can also be connected thereto. The first magnetic body (114_1) and the second magnetic body (114_2) can be arranged between the first coil body (112_1) and the second coil body (112_2), which are coupled to the first fixed plate (111_1) and the second fixed plate (111_2). The first magnetic body (114_1) can be spaced apart from the first coil body (112_1) in the second direction and can face each other. The second magnetic body (114_2) can be spaced apart from the second coil body (112_2) in the first direction and can face each other.

The first magnetic body (114_1) can rotate in synchronization with the rotation of the first rotary plate (113_1). The second magnetic body (114_2) can rotate in synchronization with the rotation of the second rotary plate (113_2). As described above, the first rotary plate (113_1) and the second rotary plate (113_2) are connected to each other and can rotate together, so that when the non-powered wheel (100) rotates, the first magnetic body (114_1) and the second magnetic body (114_2) coupled to the central rotary plate (114) can also rotate together.

When the power wheel (200) moves in a straight line, the non-power wheel (100) rotates together and rotates the central rotating plate (114) of the non-power generator (110) to generate primary electric energy. In addition, even if the non-power wheel (100) reduces acceleration at some point while rotating, the non-power generator (110) can maintain the original rotational motion due to the acceleration force that has already occurred, thereby further increasing the efficiency of the primary electric energy.

Even if the non-powered wheel (100) stops rotating through the linear motion of the means of transportation (10), the wheel (121) of the non-powered wheel (100) and the central rotary plate (114) coupled with the wheel (120) and the first and second rotary plates (113_1, 113_2) around the rotation axis (115) can continue to rotate in conjunction with the acceleration force of the rotational kinetic energy generated before the rotation of the non-powered wheel (100) stops due to the interlocking rotation gear device (116). At this time, secondary electric energy can be generated in the first magnetic body (114_1) and the second magnetic body (114_2) coupled with the central rotary plate (114) fixed to the interlocking rotation gear device (116).

When the power wheel (200) moves in a straight line, the non-power wheel (100) rotates together and the vehicle (10) moves in a straight line. At this time, an air flow (wind power) is generated around the vehicle (10). This air flow (wind power) enters the air pressure tank (118) installed on the outside of the non-power generator (110). The air flow (wind power) that enters through the air pressure tank (118) is sent back into the non-power generator (110). At this time, the central rotating plate (114) combined with the interlocking rotating gear device (116) and the plate (114_3), which is a wind blade, are rotated, so that tertiary electric energy can be generated by the first magnetic body (114_1) and the second magnetic body (114_2) included in the non-power generator (110).

In any case, when the non-power wheel (100) rotates, the magnetic field between the first magnetic body (114_1), the second magnetic body (114_2) and the first coil body (112_1), the second coil body (112_2) can change. In other words, as the non-power wheel (100) rotates, the magnetic field between the first directional electromagnetic band (111_3) and the first coil body (112_1) and the second directional electromagnetic band (111_4) and the second coil body (112_2) in the first magnetic body (114_1) and the second magnetic body (114_2) changes, and electric energy can be generated.

Referring again to FIGS. 1 and 2, the power wheel (200) may include a power drive unit (210). The power drive unit (210) may only be included in the power wheel (200). In other words, the power drive unit (210) may not be included in the non-power wheel (100).

The power drive unit (210) may be included within the power wheel (200) or may be mounted outside the power wheel (200). The third kinetic energy generated by the power providing unit (400) may be provided to the power wheel (200) through the power drive unit (210).

In other words, the power wheel (200) can generate fourth kinetic energy using third kinetic energy and move the vehicle (10) through friction with the ground.

For example, when a rider of a vehicle (10), i.e., an electric bicycle, steps on a pedal to operate the vehicle (10), the power control unit (500) can recognize this as an operation signal of the vehicle (10). The power control unit (500) can control the battery unit (300) included in the vehicle (10) to provide electric energy to the power supply unit (400). The power supply unit (400) can generate third kinetic energy using the electric energy and transmit it to the power wheel (200) through the power drive unit (210).

The power wheel (200) can generate the fourth kinetic energy using the third kinetic energy. The vehicle (10) can move in a straight line using the fourth kinetic energy of the power wheel (200) and the frictional force between the power wheel (200) and the ground. In other words, the vehicle (10) can generate the first kinetic energy using the fourth kinetic energy of the power wheel (200). When the vehicle (10) generates the first kinetic energy, the non-power wheel (100) can generate the second kinetic energy using the frictional force between the non-power wheel (100) and the ground.

Due to the secondary kinetic energy, the non-powered wheel (100) can rotate. Also, the primary electric energy can be generated when the non-powered wheel (100) rotates, either with the primary or secondary kinetic energy or with any kinetic energy. Also, even if the non-powered wheel (100) rotates and then reduces acceleration at some point, the efficiency of the primary electric energy can be further increased by the acceleration force that has already occurred. Also, even if the non-powered wheel (100) rotates and then stops, secondary electric energy is generated by the acceleration force that has already occurred, and the non-powered generator (110) can generate tertiary electric energy through the air flow that occurs when the vehicle (10) moves forward and provide it to the battery unit (300).

FIG. 13 is an exemplary diagram showing a transportation means, which is an object according to an embodiment of the present invention. Hereinafter, for convenience of explanation, contents similar to or identical to the above-described contents are briefly described or omitted.

Referring to FIGS. 1 and 13, the means of transportation (10) according to some embodiments may be an electric kickboard.

The non-powered wheel (100) may include a non-powered generator (110).

The non-powered generator (110) may only be included in the non-powered wheel (100). In other words, the non-powered generator (110) may not be included in the power wheel (200).

The power wheel (200) may include a power drive unit (210).

The power drive unit (210) may only be included in the power wheel (200). In other words, the power drive unit (210) may not be included in the non-power wheel (100).

For example, when a rider of an electric kickboard of a means of transportation (10) operates an accelerator to operate the means of transportation (10), the power control unit (500) can recognize this as an operation signal of the means of transportation (10). The power control unit (500) can control the battery unit (300) included in the means of transportation (10) to provide electric energy to the power providing unit (400). The power providing unit (400) can generate third kinetic energy using the electric energy and transmit it to the power wheels (200) through the power driving unit (210).

The power wheel (200) can generate the fourth kinetic energy using the third kinetic energy. The vehicle (10) can move forward and move in a straight line using the fourth kinetic energy of the power wheel (200) and the frictional force between the power wheel (200) and the ground. In other words, even if the vehicle (10) generates the first kinetic energy using the fourth kinetic energy of the power wheel (200), the vehicle (10) can move forward and generate electric energy.

In addition, when the vehicle (10) generates the first kinetic energy, the non-powered wheel (100) can generate the second kinetic energy by using the frictional force between the non-powered wheel (100) and the ground. At this time, due to the second kinetic energy, the non-powered wheel (100) can rotate and generate the first electric energy, and also, even if the non-powered wheel (100) reduces the acceleration at some point while rotating, the efficiency of the first electric energy can be further increased by the acceleration that has already occurred. In addition, even if the power wheel (200) stops moving and the non-powered wheel (100) also stops, the second electric energy can be generated by the rotational acceleration that has already occurred. In addition, when the vehicle (10) moves forward, the non-powered generator (110) can generate the third electric energy through the air flow that is generated and provide it to the battery unit (300).

Fig. 14 is an exemplary diagram showing a transportation means, which is an object according to an embodiment of the present invention. In the following, for the convenience of explanation, contents similar to or identical to the above-described contents are briefly described or omitted.

Referring to FIGS. 1 and 14, the vehicle (10) according to some embodiments may be an electric scooter.

The non-powered wheel (100) may include a non-powered generator (110). The non-powered generator (110) may only be included in the non-powered wheel (100). In other words, the non-powered generator (110) may not be included in the powered wheel (200). The powered wheel (200) may include a power drive unit (210).

The power drive unit (210) may only be included in the power wheel (200). In other words, the power drive unit (210) may not be included in the non-power wheel (100).

For example, when a rider of a vehicle (10), i.e., an electric scooter, operates an accelerator to operate the vehicle (10), the power control unit (500) can recognize this as an operation signal of the vehicle (10).

The power control unit (500) can control the battery unit (300) included in the transportation means (10) to provide electric energy to the power supply unit (400). The power supply unit (400) can generate third kinetic energy using the electric energy and transmit it to the power wheel (200) through the power drive unit (210).

The power wheel (200) can generate the fourth kinetic energy using the third kinetic energy. The vehicle (10) can move in a straight line using the fourth kinetic energy of the power wheel (200) and the frictional force between the power wheel (200) and the ground. In other words, the vehicle (10) can generate the first kinetic energy using the fourth kinetic energy of the power wheel (200). When the vehicle (10) generates the first kinetic energy, the non-power wheel (100) can generate the second kinetic energy using the frictional force between the non-power wheel (100) and the ground. At this time, the non-power wheel (100) can rotate due to the second kinetic energy. In this way, the non-power wheel (100) rotates using the first and second kinetic energies, and the vehicle can move forward.

Even at this time, due to the secondary kinetic energy, the non-powered wheel (100) can rotate to generate primary electric energy, and also, even if the non-powered wheel (100) reduces acceleration at some point while rotating, the efficiency of the primary electric energy can be further increased by the acceleration force that has already occurred. In addition, even if the power wheel (200) stops moving and the non-powered wheel (100) also stops, secondary electric energy can be generated by the rotational acceleration force that has already occurred. In addition, the non-powered generator (110) can generate tertiary electric energy through the air flow that is generated as the vehicle (10) moves forward and provide it to the battery unit (300).

Fig. 15 is an exemplary diagram showing a transportation means, which is an object according to an embodiment of the present invention. In the following, for the convenience of explanation, contents similar to or identical to the above-described contents are briefly described or omitted.

Referring to FIGS. 1 and 15, the vehicle (10) according to some embodiments may be an electric vehicle.

The non-powered wheel (100) may include a non-powered generator (110). The non-powered generator (110) may only be included in the non-powered wheel (110). In other words, the non-powered generator (110) may not be included in the powered wheel (200). The powered wheel (200) may include a power drive unit (210).

The power drive unit (210) may only be included in the power wheel (200). In other words, the power drive unit (210) may not be included in the non-power wheel (100).

For example, when a passenger of a vehicle (10), i.e., an electric vehicle, steps on an accelerator pedal to operate the vehicle (10), the power control unit (500) can recognize this as an operation signal of the vehicle (10). The power control unit (500) can control the battery unit (300) included in the vehicle (10) to provide electric energy to the power supply unit (400). The power supply unit (400) can generate third kinetic energy using the electric energy and transmit this to the power wheels (200) through the power drive unit (210). The power wheels (200) can generate fourth kinetic energy using the third kinetic energy.

The vehicle (10) can move in a straight line by using the fourth kinetic energy of the power wheel (200) and the frictional force between the power wheel (200) and the ground. In other words, the vehicle (10) can generate the first kinetic energy by using the fourth kinetic energy of the power wheel (200). When the vehicle (10) generates the first kinetic energy, the non-powered wheel (100) can generate the second kinetic energy by using the frictional force between the non-powered wheel (100) and the ground. At this time, the non-powered wheel (100) can rotate due to the second kinetic energy.

Even at this time, the non-powered wheel (100) can rotate due to the secondary kinetic energy to generate primary electric energy, and also, even if the non-powered wheel (100) reduces acceleration at some point while rotating, the efficiency of the primary electric energy can be further increased by the acceleration force that has already occurred. In addition, even if the power wheel (200) stops moving and the non-powered wheel (100) also stops, secondary electric energy can be generated by the rotational acceleration that has already occurred. In addition, the non-powered generator (110) can generate tertiary electric energy through the air flow that is generated as the vehicle (10) moves forward and provide it to the battery unit (300).

Although examples of transportation means (10) according to some embodiments of the present invention have been described using FIGS. 2 and 13 to 15, the embodiments are not limited thereto. The technical idea of the present invention can be applied to various transportation means other than the aforementioned transportation means (10), and those skilled in the art in the art can make various modifications without departing from the scope of the present invention.

According to some embodiments, the power drive unit (210) may be included only in the power wheel (200), and the non-power generator (110) may be included only in the non-power wheel (100). That is, the power drive unit (210) is mounted on the power wheel (200), and the non-power generator (110) is mounted on the non-power wheel (100), so that the weight of the wheels of the vehicle (10) can be distributed to balance the weight, thereby preventing safety accidents.

In some embodiments, the power drive unit (210) may be included only in the power wheel (200), and the non-power generator (110) may be included only in the non-power wheel (100).

Accordingly, if either the power drive unit (210) or the non-power generator (110) malfunctions, only one of the power wheel (200) or the non-power wheel (100) needs to be replaced or repaired, thereby increasing the convenience of maintenance/repair.

According to some embodiments, the power drive unit (210) may be included only in the power wheel (200), and the non-power generator (110) may be included only in the non-power wheel (100). That is, since there is no need to consider physical interference between the power drive unit (210) and the non-power generator (110), wheels of various sizes can be easily designed, and wheels with small volume can be easily designed. In addition, since there is no physical interference between the power drive unit (210) and the non-power generator (110), the convenience of maintenance can also be increased.

In some embodiments, the power drive unit (210) may be included only in the power wheel (200), and the non-power generator (110) may be included only in the non-power wheel (100). That is, since the power wheel (200) includes only the power drive unit (210), a lightweight power wheel (200) can be designed.

Since the weight of the power wheel (200) is relatively light, the power wheel (200) can be designed. Since the weight of the power wheel (200) is relatively light, the energy loss that occurs when the fourth kinetic energy is generated in the power wheel (200) can be relatively small. If the power drive unit (210) and the non-power generator (110) are included in one wheel, the moment of inertia of the power wheel (200) increases due to the weight of the non-power generator (110). If the moment of inertia of the power wheel (200) increases, the power drive unit (210) consumes relatively more energy to rotate the power wheel (200). Therefore, in this case, the electric energy consumption of the battery unit (300) increases, which may ultimately cause a decrease in energy efficiency. However, the means of transport (10) according to some embodiments of the present invention can minimize energy loss that occurs when the powered wheel (200) generates the fourth kinetic energy by distributing the power drive unit (210) to the powered wheel (200) and the non-power generator (110) to the non-power wheel (100).

According to some embodiments, the power drive unit (210) may be included only in the power wheel (200), and the non-power generator (110) may be included only in the non-power wheel (100). Accordingly, interference between the electric energy generated when the power wheel (200) is driven and the electric energy generated in the non-power wheel (100) does not occur, so that malfunction of the vehicle (10) is reduced and electric energy loss can be minimized.

In some embodiments, by mounting a non-powered generator (110) on a non-powered wheel (100), energy efficiency can be increased because the non-powered wheel (100) generates electrical energy by utilizing secondary kinetic energy that would otherwise be wasted.

According to some embodiments, the present invention can first obtain primary electric energy through linear motion of a power wheel (200) and a non-power wheel (100).

In addition, even if the linear motion of the power wheel (200) and the non-power wheel (100) is reduced at some point, the magnetic body (114_1, 114-2) can maintain the original rotational speed due to the rotational acceleration force that has already occurred, thereby generating electric energy with higher efficiency than primary electric energy.

In addition, even if the power wheel (200) stops moving and the non-power wheel (100) also stops, the magnetic body (114_1, 114_2) can continue to rotate by the linked rotation gear device (116) in conjunction with the rotational acceleration that has already occurred, thereby generating secondary electric energy.

Additionally, tertiary electrical energy can be generated through the flow of air (wind power) that occurs during the linear movement of a transport device.

Therefore, the technology of the present invention can obtain more efficient electric energy in multiple ways by one linear motion energy.

The present invention described above can contribute to the development of transportation systems by improving the performance and usability of wind power-powered transportation devices and ensuring the energy efficiency and safety of powered and non-powered transportation means.
