[0003] Technological development is ongoing, particularly in power generation methods utilizing piezoelectric elements. However, piezoelectric elements face price competitiveness issues due to maintenance costs, and durability issues, particularly under the intense pressure exerted by vehicles on roads, pose a significant challenge. Therefore, technological development is focused on applying them to pavement blocks to utilize the pressure exerted by pedestrians.

[0004] Since the past, continuous research and development has been conducted on technology that converts vertical motion according to the pressure applied by a vehicle into rotational motion of complex gears by applying physical gears. In relation to US 7067932 B1: System for generating electricity by using gravitational mass and / or momentum of moving vehicle, KR 2009-0045181 A: Self-generating device using passing vehicle, JP 2013-227952 A: Power generation device, CN 103696918 BA: Vibration generating device for highway and incidental to the humps of the device, KR 2012-0100366 A: Power generation device using the weight of a vehicle or a person, KR 2011-0128070 A: Speed ​​prevention device, KR 1345562 B1: Speed ​​bump self-generating device, KR 0878898 B1: Speed ​​bump structure with power generation function, KR 1263897 B1: Self-generating block, KR 2495431 B1: Self-generating device using moving vehicle, JP 2010-213558 A: Method of generating power on a road, US 201004713 A: Road vehicle actuated energy device (road vehicle actuated energy device), KR 2002-0012487 A: Road marking device, KR 1989-0016733 A: Pressure generating device, KR 2011-0115197 A: There is a speed-sensitive speed bump.

[0005] Conventional technologies generate power by converting the vertical motion of a vehicle's wheels into rotational motion of gears. To convert short-distance, reciprocating vertical motion into high gear rotation speeds, complex gear structures are employed. During vertical forward motion, the gears rotate forward, and during vertical reverse motion, a clutch mechanism is employed to ensure reverse rotation. When a power generator with such a complex gear structure is installed on the road, the continuous, high pressure exerted by the vehicle can significantly wear the gears, leading to malfunctions or damage. Specifically, the continuous, high pressure from the front and rear wheels of a vehicle passing through the generator on the road is transmitted to the generator. This pressure from the front wheels rotates the gears, while the rear wheels exert strong pressure again, significantly increasing gear wear. Furthermore, the high speed of the moving vehicle can cause the gears to momentarily break before they can return to their initial positions, posing a serious problem.

[0006] The present invention provides a self-generating device that can solve the problems of conventional technologies while increasing charging efficiency and has a simple structure that is easy to install in spaces where physical pressure is applied toward the ground, such as sidewalks where people walk, roads where cars pass, and speed bumps.

[0007] In addition, the present invention provides a self-powering device that can solve problems such as increased wear rate and damage due to strong external force at the meshing point between gears in a conventional gear system.

[0008] In addition, the present invention provides a self-generating device that can solve the problem of frequent damage or destruction of components of devices due to strong external force when the synchronization between gears is broken due to strong pressure repeatedly and very quickly by the front and rear wheels of a vehicle. That is, the problem of causing malfunction or damage to the generator device due to the degree of gear wear caused by repeated pressure of the lifting shaft for a short moment by the front and rear wheels of a vehicle being large, and the serious problem of causing the gears to be instantaneously destroyed by pressure from the rear wheels of a vehicle when the gears are not precisely aligned with other gears during the continuous up-and-down movement of a gear that moves vertically after gear wear occurs over time is provided.

[0009] In addition, the present invention provides a self-power generation device that can increase the rotation speed of a rotating gear by allowing only one pressing force to be applied to one vehicle, and can reduce the complexity of the device and make it compact by enabling simple synchronization of the rotating gear and the pressing module.

[0041] The present invention is capable of various modifications and embodiments. Therefore, specific embodiments are illustrated in the drawings and described in detail in the detailed description. The effects and features of the present invention, as well as the methods for achieving them, will become clear with reference to the embodiments described in detail below together with the drawings. However, the present invention is not limited to the embodiments disclosed below and can be implemented in various forms. In the following embodiments, the terms "first," "second," etc. are not used in a limiting sense but are used for the purpose of distinguishing one component from another. Furthermore, the singular expression includes the plural expression unless the context clearly indicates otherwise. Furthermore, terms such as "include" or "have" indicate the presence of a feature or component described in the specification, and do not preemptively exclude the possibility that one or more other features or components may be added. Furthermore, in the drawings, the sizes of components may be exaggerated or reduced for convenience of explanation. For example, the size and thickness of each component shown in the drawings are arbitrarily shown for convenience of explanation, and thus the present invention is not necessarily limited to what is shown.

[0042] Hereinafter, embodiments of the present invention will be described in detail with reference to the attached drawings. When describing with reference to the drawings, identical or corresponding components are given the same drawing reference numerals, and redundant descriptions thereof will be omitted.

[0043] FIG. 1 illustrates an example of a self-generation device installed on a road where vehicles such as vehicles, motorcycles, and bicycles pass, according to an embodiment of the present invention. FIG. 2 schematically illustrates a self-generation device installed on a sidewalk (a) and a self-generation device installed on a road corresponding to a speed bump (b).

[0044] Referring to FIGS. 1 and 2, a self-generation device (100) according to an embodiment of the present invention may be installed on a road on which a vehicle, such as an automobile (10) or a bicycle / motorcycle (70), travels. Furthermore, the self-generation device (100) may be installed on a pedestrian walkway. Installation here may mean being buried at a point on the road or installed inside a speed bump (20) on the road.

[0045] The self-generating device (100) can generate electricity by utilizing the pressing force generated from the load applied to the ground by a vehicle such as an automobile (10) or a bicycle / motorcycle (70) while the vehicle is in motion. For example, electricity can be generated by utilizing the pressing force generated from the load through the wheels of the automobile (10) or the bicycle / motorcycle (70). The main controller (30) installed on the road can control the operation of the self-generating device (100), store at least a portion of the electricity generated from the self-generating device (100), and use at least a portion as driving power for various display devices (40) on the road or sidewalk, including streetlights. The display devices (40) here can be, but are not limited to, signposts, LED lights in tunnels, electronic billboards, milestones, signposts, streetlights, cameras, etc.

[0046] The self-generation device (100) may be configured in multiple units. The multiple self-generation devices (100) may be aligned with each other in a direction perpendicular to the direction of movement of a vehicle, such as an automobile (10) or a bicycle / motorcycle (70), and may be spaced apart from each other by a predetermined distance. If the self-generation device (100) is installed on a road on which vehicles travel, the separation distance here may be determined based on the distance between the left and right wheels of a typical vehicle.

[0047] At least a portion of the self-generation device (100) may be buried in a self-generation area (60) on a sidewalk. Additionally, the self-generation device (100) may be buried in a road. In various embodiments, the self-generation device (100) may be installed on a speed bump (20). When a vehicle such as an automobile (10) or a bicycle / motorcycle (70) moves, a pressure force from the wheels may be transmitted to a partial area of ​​the speed bump (20), and a partial area may move downward according to the load and transmit the pressure to the self-generation device (100).

[0048] Meanwhile, a portion (20p) of the speed bump (20) is subjected to downward pressure by the vehicle's wheels, causing the portion (20p) to move downward, which is synchronized with the instantaneous downward movement of the wheels. In addition, the maximum downward movement distance from the initial position of the pressurization module (130) by the vehicle's wheels may be substantially equal to the downward movement distance of the aforementioned portion (20p) and the instantaneous downward movement distance of the vehicle's wheels.

[0049] The pressure applied to the self-generating device (100) can be divided into primary pressure and secondary pressure at different times. For example, as a vehicle such as an automobile (10) or a bicycle / motorcycle (70) moves, the front wheels of the vehicle can form primary pressure and the rear wheels can form secondary pressure. In addition, the rear wheels of the first vehicle can form primary pressure and the front wheels of the second vehicle that moves next to the first vehicle can form secondary pressure. In addition, among a number of people moving on foot, the pedaling force of one person can form primary pressure and the pedaling force of another person can form secondary pressure.

[0050] Hereinafter, the self-generating device (100) is described as being driven by the load of a vehicle, but is not limited thereto, and may also be driven by the load of other means of transportation or a person moving on foot.

[0083] 1) First state

[0084] Referring further to FIGS. 12a and 13b, in the initial state of the self-power generation device (100) which is the first state, the pressurization module (200) can be positioned at an initial position whose height from the lower support member (113) is the 1-1 height (h11). In addition, the pressurization gear (500) connected to the inner support member (112) can be positioned at an initial position whose height from the lower support member (113) is the 2-1 height (h21) according to the initial shape of the internal elastic body. In addition, the pressurization gear (500) is not in gear contact with the rotation gear (700). In addition, the stopper module (800), the auxiliary pressurization member (400), and the rotation guide member (600) can be aligned at the initial position. In addition, a part of the guide slope (602) of the rotation guide part (600) may be adjacent to or in contact with the rotation induction protrusion (111ap) located between the pressurizing gear (500) and the rotation guide part (600). The rotation induction protrusion (111ap) may be formed to protrude from the inner surface of the front case (111a), but is not limited thereto. The rear surface of the rotation guide part (600) may face the front surface of the auxiliary pressurizing part (400).

[0085] 2) Second state

[0086] Referring further to FIGS. 13a and 14b, when the wheels of the vehicle pressurize a portion (20p) of the pressurization module (200) as the vehicle moves, the self-power generation device (100) can switch to a second state. When the pressurization module (200) moves downward a predetermined distance, the first and second main return parts (321, 322) contract. In addition, the height of the pressurization module (200) from the lower support part (113) can become the first-second height (h12). During the downward movement of the pressurization gear (500), the gear teeth on the gear area (510) of the pressurization gear (500) can engage with the rotation gear (700) to rotate the rotation gear (700) in a first direction. Here, the first direction can be a clockwise direction. In various embodiments, when the pressurizing module (200) moves so that the height from the lower support (113) becomes the first-second height (h12), the pressurizing gear (500) also becomes the second-second height (h22) from the lower support (113). The gear engagement between the gear teeth on the gear area (510) of the pressurizing gear (500) and the rotation gear (700) can be released, and accordingly, the rotation gear (700) can maintain rotation in the first direction at a predetermined rotational speed by the remaining rotational force and can stop rotation after a predetermined period of time by the resistance of the motor unit (900). The rotation guide unit (600) connected to the pressurizing gear (500) can move downward together with the pressurizing gear (500). And, the rotation guide part (600) can be rotated at a first angle by the rotation inducing protrusion (111ap) located between the pressurized gear (500) and the rotation guide part (600). That is, as the rotation guide part (600) moves downward, the rotation inducing protrusion (111ap) of the rotation guide part (600) comes into contact with the guide slope (602) and moves along the guide slope (602) and the front surface of the rotation guide part (600), thereby rotating the rotation guide part (600) counterclockwise by a first angle.In addition, as the rotation guide part (600) rotates at the first angle in the counterclockwise direction, the end of the auxiliary pressurized rotation part (420) comes into contact with the second protruding area (620) of the rotation guide part (600), and force is applied to the end of the auxiliary pressurized rotation part (420) toward the rear of the rotation guide part (600), so that the rotation guide part (600) rotates at a predetermined angle in the counterclockwise direction. In addition, as the pressure gear (500) moves downward, at least a portion of the lower surface of the pressure gear (500) comes into contact with the stopper protruding inclined surface (813a), which is the upper surface of the stopper protruding portion (813), and moves along the stopper protruding inclined surface (813a). And, as the pressurizing gear (500) presses the stopper protrusion inclined surface (813a) and moves along the stopper protrusion inclined surface (813a), the rotation stopper part (810) can be rotated clockwise by a predetermined angle. And, as the rotation stopper part (810) rotates by a predetermined angle, pressure is transmitted to the elevation stopper part (820) connected to the rotation stopper part (810), and the elevation stopper part (820) receives a reaction force to return to the initial position. And, as the pressurizing gear (500) becomes the 2-2 height (h22), the rotation stopper part (810) is rotated counterclockwise by the reaction force applied to the elevation stopper part (820), and accordingly, the stopper protrusion part (813) can be inserted into the stopper insertion groove (530).

[0087] Meanwhile, the 1-1 height (h11) is higher than the 1-2 height (h12), and the 2-1 height (h21) is higher than the 2-2 height (h22).

[0088] 3) Third state

[0089] Referring further to FIGS. 14a and 14b, when the pressure applied to the pressurizing module (200) is released, the pressurizing module (200) can be returned to the initial position, which is the 1-1 height (h11), according to the transition movement of the contracted first and second main return parts (321, 322) to the initial position. As the pressurizing module (200) rises, the auxiliary pressurizing part (400) installed in the pressurizing module (200) rises. As the auxiliary pressurizing part (400) rises, the end of the auxiliary pressurizing rotation part (420) moves along the second protruding area (620) of the rotation guide part (600), and as the contact between the auxiliary pressurizing rotation part (420) and the second protruding area (620) is released, the auxiliary pressurizing rotation part (420) rotates clockwise at a predetermined angle to become the initial position of the first state. And, a part of the lower region of the auxiliary pressurized rotation part (420) is inserted into the guiding space (601) of the rotation guide part (600). At this time, the pressurized gear (500) is maintained in a state of being connected to the stopper module (800), so the height of the pressurized gear (500) is maintained at the 2-2 height (h22).

[0090] 4) Fourth state

[0091] Referring further to FIGS. 15a and 15b, when the vehicle's wheels pressurize the pressurization module (200) for the second time, the pressurization module (200) switches from the 1-1 height (h11) to the 1-2 height (h12), and the first and second main return parts (321, 322) are contracted. In addition, as the pressurization module (200) moves downward, the auxiliary pressurization rotation part (420) moves downward. At this time, the area of ​​the auxiliary pressurization rotation part (420) inserted into the guiding space (601) of the rotation guide part (600) increases. As the pressurizing module (200) reaches the first-second height (h12), the auxiliary pressurizing rotation part (420) applies downward pressure to the upper surface of the second stopper part (812), and accordingly, the rotation stopper part (810) rotates clockwise again at a predetermined angle. At this time, the stopper protrusion part (813) is pulled out from the stopper insertion groove (530), and the fastening between the pressurizing gear (500) and the stopper module (800) is released.

[0092] 5) Fifth state

[0093] Referring further to FIGS. 16a and 16b, when the pressure from the wheels of the vehicle is released, the contracted first and second main return parts (321, 322) expand and return to the initial position, and accordingly, the pressurizing module (200) can move upward and change from the 1-2 height (h12) to the 1-1 height (h11). In addition, the pressurizing gear (500) can also move upward and change from the 2-1 height (h21) to the 2-2 height (h22). As the pressurizing module (200) rises, the auxiliary pressurizing part (400) also rises, and as the pressure applied by the auxiliary pressurizing rotation part (420) to the upper surface of the second stopper part (812) is released, the rotation stopper part (810) rotates counterclockwise at a predetermined angle to return to the initial position. And, as the auxiliary pressurized rotation part (420) rises, it is withdrawn from the guiding space (601) of the rotation guide part (600), and the auxiliary pressurized rotation part (420) faces the rear surface of the rotation guide part (600). In addition, as the pressurized gear (500) rises, the front surface of the rotation guide part (600) comes into contact with the rotation induction protrusion (111ap) and rotates clockwise at a predetermined angle, thereby returning to the same position as the first state.

[0094] At this time, since the pressurizing module groove (201) is provided on the lower side of the pressurizing module (200), the movement distance of the pressurizing module (200) during the downward and upward movement becomes longer than the movement distance of the rotation guide part (600) according to the downward and upward movement of the pressurizing gear (500). Therefore, when switching from the fourth state to the fifth state, the auxiliary pressurizing part (400) is raised together with the rotation guide part (600), but when the pressurizing module (200) becomes the 1-1 height (h11), the auxiliary pressurizing rotation part (420) is completely pulled out from the guiding space (601) of the rotation guide part (600), so that the auxiliary pressurizing rotation part (420) faces the rear surface of the rotation guide part (600), and the auxiliary pressurizing rotation part (420) can be switched to the same initial position as the first state.

[0095] When the pressurizing gear (500) rises, the auxiliary rotation gear (730) can be rotated in the reverse direction to generate additional power. In addition, the gear engagement between the pressurizing gear (500) and the auxiliary rotation gear (730) is released as the pressurizing gear (500) returns to its initial position. At this time, the remaining rotational power of the auxiliary rotation gear (730) is naturally dissipated, thereby further increasing the amount of power generated.

[0096] Meanwhile, the aforementioned primary pressurization is pressurization by the front wheels of the vehicle, and the secondary pressurization is pressurization by the rear wheels of the vehicle. In various embodiments, the aforementioned primary pressurization is pressurization by the rear wheels of the first vehicle, and the secondary pressurization is pressurization by the front wheels of a second vehicle different from the first vehicle.

[0097] Meanwhile, referring to FIG. 3b, the inner support part (112) of the self-power generation device (100) according to various embodiments of the present invention can be combined with the outer case (111).

[0098] The inner support member (112) can serve as a cover for the outer case (111) and cover the receiving space (110s). The first and second main support members (311, 312) can be installed on the upper surface of the inner support member (112). In addition, the first main return member (321) can connect the first main support member (311) and the pressurizing module (200) to each other, and the second main return member (322) can connect the second main support member (312) and the pressurizing module (200) to each other. The distance between the lower surface of the pressurizing module (200) and the front surface of the inner support member (112) can be changed by the external force applied to the pressurizing module (200) and the release of the applied external force. The inner support member (112) serves as a cover for the outer case (111) and covers the receiving space (110s), thereby preventing contaminants from entering the receiving space (110s).

[0099] Figures 17 to 21 schematically illustrate the interior of the self-power generation device according to Figure 3b. The operating method can be described in the same way as the self-power generation device according to Figure 3.

[0100] 1) First state

[0101] Referring further to FIG. 17, the pressurizing module (200), the auxiliary pressurizing unit (400), the pressurizing gear (500), the rotation guide unit (600), and the stopper module (800) constituting the self-generating device (100) in the first state may have an initial position as shown in FIG. 17.

[0102] 2) Second state

[0103] Referring further to Fig. 18, when the wheels of the vehicle pressurize the pressurization module (200) for the first time as the vehicle moves, the self-power generation device (100) can switch to the second state. The pressurization module (200) moves downward a predetermined distance, and the first and second main return parts (321, 322) contract. As the pressurization gear (500) moves downward, the rotation gear (700) can be rotated by the pressurization gear (500). The rotation guide part (600) connected to the pressurization gear (500) can move downward together with the pressurization gear (500). In addition, the rotation guide part (600) can be rotated at a first angle by the rotation induction protrusion (111ap) located between the pressurization gear (500) and the rotation guide part (600). In addition, as the rotation guide part (600) rotates at the first angle in the counterclockwise direction, a force is applied to the end of the auxiliary pressurized rotation part (420) toward the rear of the rotation guide part (600), so that the rotation guide part (600) rotates at a predetermined angle in the counterclockwise direction. In addition, as the pressure gear (500) moves downward, at least a portion of the lower surface of the pressure gear (500) comes into contact with the stopper protrusion inclined surface (813a), which is the upper surface of the stopper protrusion part (813), and moves along the stopper protrusion inclined surface (813a). And, as the pressurizing gear (500) presses the stopper protrusion inclined surface (813a) and moves along the stopper protrusion inclined surface (813a), the rotating stopper part (810) rotates clockwise by a predetermined angle, and the contracted lifting elastic body (821) inside the lifting stopper part (820) contracts. And, by the return force of the lifting elastic body (821), the rotating stopper part (810) rotates counterclockwise by a predetermined angle, and the stopper protrusion part (813) can be inserted into the stopper insertion groove (530). Therefore, the pressing gear elastic body (590) installed inside the pressing gear (500) and connected to the inner support part (112) has an elastic force to contract as it extends, but the pressing gear (500) is locked to the stopper module (800) and maintains its current position.

[0104] 3) Third state

[0105] Referring further to Fig. 19, when the pressure applied to the pressurizing module (200) is released, the pressurizing module (200) can move to the initial position in the first state by the return force of the contracted first and second main return parts (321, 322). Then, the auxiliary pressurizing part (400) rises together with the pressurizing module (200). Then, when the contact between the auxiliary pressurizing rotation part (420) and the second protruding area (620) is released, the auxiliary pressurizing rotation part (420) rotates clockwise at a predetermined angle to return to the initial position in the first state. Then, a part of the lower area of ​​the auxiliary pressurizing rotation part (420) is inserted into the guiding space (601) of the rotation guide part (600).

[0106] 4) Fourth state

[0107] Referring further to FIG. 20, when the vehicle's wheels pressurize the pressurization module (200) for the second time, the pressurization module (200) moves downward again, and the first and second main return parts (321, 322) are contracted. Then, the auxiliary pressurization rotation part (420) moves downward together with the pressurization module (200). At this time, the auxiliary pressurization rotation part (420) is inserted deeper into the guiding space (601) of the rotation guide part (600). Then, the auxiliary pressurization rotation part (420) provides downward pressure to the upper surface of the second stopper part (812), and accordingly, the rotation stopper part (810) rotates clockwise again at a predetermined angle, and the lifting elastic body (821) is compressed. At this time, the stopper protrusion (813) is pulled out from the stopper insertion groove (530), and the engagement between the pressurizing gear (500) and the stopper module (800) is released. Accordingly, the pressurizing module (200) receives a force to return to the initial position in the first state due to the elastic force of the pressurizing gear elastic body (590).

[0108] 5) Fifth state

[0109] Referring further to Fig. 21, when the pressure from the wheels of the vehicle is released, the contracted first and second main return parts (321, 322) are returned to the initial position by the return force, and the pressurizing module (200) moves upward accordingly. The auxiliary pressurizing part (400) rises together with the pressurizing module (200). Then, the pressure that the auxiliary pressurizing rotation part (420) applies to the upper surface of the second stopper part (812) is released. Then, the rotation stopper part (810) rotates counterclockwise at a predetermined angle to be returned to the initial position by the elastic force of the lifting elastic body (821). Then, as the auxiliary pressurizing rotation part (420) rises, it is withdrawn from the guiding space (601) of the rotation guide part (600), and the auxiliary pressurizing rotation part (420) faces the rear surface of the rotation guide part (600). In addition, as the pressurized gear (500) rises, the front surface of the rotation guide portion (600) comes into contact with the rotation induction protrusion (111ap) and rotates clockwise at a predetermined angle, thereby returning to the same position as the first state.
