[0002] With the introduction of the new climate system and the declaration of carbon neutrality, the widespread application of renewable energy is just around the corner. Regarding the power generation methods for obtaining renewable energy, the wind method of US2022-0349378 A1 (Road surface electrical generator and sensor), the friction method of KR 1992235 B1 (road power generation method using friction between wheels), KR 2022-0089295 A (highway power generation device using friction between wheels and road surface), EP 4016810 A1 (Installation for power generation by means of vehicular traffic), KR 2263991 B1 (power generation device), KR 2021-0086156 A (power generation device using vehicle load), KR0490439 Y1 (embedded power generation device), and the hydraulic method of KR 2326340B1 (road power generation device utilizing the load of passing vehicles), US2021-0391769A1 (Compressed air accumulation system for power generation)'s air compression method, KR 2021-0001262U (power generation device based on vehicle-road interaction utilizing electromagnetic induction phenomenon), KR 1958685B1 (road surface-mounted power generation device)'s electromagnetic induction method, KR 2218591 B1 (energy generation unit and intelligent highway system utilizing it)'s piezoelectric method, KR 1989778 B1 (power generation system with a dust removal structure that also serves as a speed bump)'s physical gear structure application method, KR 10-2398852B1 (self-generating floor tile module to ensure pedestrian safety), WO WO2013 / 038415 (Modular piezoelectric generators) and other power generation technologies.

[0003] The typical example is the development of power generation technology using piezoelectric elements. However, piezoelectric elements have price competitiveness issues due to maintenance costs, and in particular, durability issues caused by the strong pressure exerted by vehicles on the road have become difficult to solve technical problems. Technology is being developed to use the pressure exerted by pedestrians on floor tiles.

[0004] We have been researching and developing technology that uses physical gears to convert the vertical motion caused by the pressure applied by the vehicle into complex gear rotational motion to generate electricity. Related to this are US 7067932B1: System for generating electricity by using gravitational mass and / or momentum of moving vehicle, KR 2009-0045181 A: Self-generating device using passing vehicles, JP 2013-227952A: 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 vehicle or human weight, KR2011-0128070 A: Overspeed prevention device, KR 1345562B1: Speed ​​bump self-generating device, KR 0878898 B1: Speed ​​bump structure with power generation function, KR 1263897B1: Self-generating block, KR 2495431 B1: Self-generating device using vehicle movement, JP 2010-213558A: Method for generating electricity on a road, US201004713 A: Road vehicle actuated energy device (road vehicle actuated energy device), KR 2002-0012487 A: Road display device, KR 1989-0016733 A: Pressure power generation device, KR 2011-0115197 A: Speed ​​sensing type speed reduction belt.

[0005] Conventional technology converts the vertical motion of the wheels into the rotational motion of the gears to generate electricity. In addition, in order to convert the high gear rotation number generated by the short-distance back-and-forth vertical motion, a complex gear structure is applied. When the vertical forward motion is performed, the gear is rotated forward, and when the vertical backward motion is performed, a clutch structure is applied to reverse the gear. In this way, when a power generation device using a complex gear structure is set on the road, the gear wears a lot due to the strong pressure continuously applied by the vehicle, which may cause the power generation device to work poorly or be damaged. That is, the strong pressure continuously generated by the front and rear wheels of a vehicle passing by the power generation device on the road will be transmitted to the power generation device. At this time, the strong pressure of the rear wheel will be increased again during the rotation of the rotating gear due to the virtual pressure of the front wheel, which is also the main reason for the serious wear between the gears. In addition, the faster speed of the moving vehicle will cause the gear to be seriously damaged due to the further increased strong pressure before it turns to the initial position. Summary of the invention

[0006] Issues to be solved

[0007] The present invention provides a self-generating device, which can solve the drawbacks of traditional technologies while improving charging efficiency, and can be easily installed in a space where physical pressure is applied to the ground, such as a sidewalk with a simple structure, a road where cars pass by, a speed bump, etc.

[0008] Furthermore, the present invention provides a self-generating device, which can solve the problems of increased wear speed and damage caused by strong external forces at the matching parts of gears in the conventional gear method.

[0009] In addition, the present invention provides a self-generating device, which can solve the problem that when the front and rear wheels of the vehicle quickly and repeatedly exert strong pressure to break the synchronization between the gears, the strong external force frequently causes damage or destruction between the device components. That is, a self-generating device is provided, which can solve the problem that the front and rear wheels of the vehicle repeatedly pressurize the lifting shaft in a short moment, thereby increasing the wear of the gears, causing the generator to work poorly or be damaged, etc.; after a period of gear wear, when the vertically moving gear continuously moves up and down, the gear meshing with other gears is not accurate, and the pressure of the rear wheel of the vehicle causes the gear to be damaged instantly.

[0010] Furthermore, the present invention provides a self-generating device which limits the virtual pressure applied by a vehicle to one time, thereby increasing the rotation speed of the rotating gear, achieving simple synchronization of the rotating gear and the pressure module, reducing the complexity of the device and achieving miniaturization.

[0011] Problem Solution

[0017] A limit module, which controls the position of the pressure gear,

[0018] When the pressure gear moves from the initial position toward the downward direction by a primary pressure applied to the pressure module, the limiting module locks the pressure gear to fix the position of the pressure gear, and the limiting module releases the locking of the pressure gear by a secondary pressure applied to the pressure module, thereby converting the pressure gear to the initial position.

[0019] On the other hand, in the self-generating device provided, the limit module includes a rotation limit part and a lifting limit part, and the lifting limit part provides a rotational force so that the rotation limit part rotates in one direction of the rotation limit part and rotates in another direction; after the rotation limit part rotates in the one direction through the pressure applied by the pressure gear, it rotates again in the other direction through the lifting limit part, thereby connecting with the pressure gear and locking the pressure gear.

[0020] On the other hand, the self-generating device provided further includes an auxiliary pressure-applying part, which provides pressure to the rotation limiting part that locks the pressure gear, so that the rotation limiting part rotates in the one direction, thereby releasing the locking of the rotation limiting part and the pressure gear, and the auxiliary pressure-applying part is arranged on the pressure module, and performs lifting and moving corresponding to the lifting and moving of the pressure module.

[0021] On the other hand, the self-generating device provided further includes a rotation guide portion, which moves corresponding to the movement of the pressure gear to control whether the auxiliary pressure portion provides pressure for the rotation limiting portion.

[0022] In another aspect, a self-generating device is provided, comprising:

[0028] When the pressure gear moves from the initial position toward the downward direction by a primary pressure applied to the pressure module, the limiting module locks the pressure gear to fix the position of the pressure gear, and the limiting module releases the locking of the pressure gear by a secondary pressure applied to the pressure module, thereby converting the pressure gear to the initial position.

[0029] On the other hand, in the self-generating device provided, the limit module includes a rotation limit part and a lifting limit part, and the lifting limit part provides a rotational force so that the rotation limit part rotates in one direction of the rotation limit part and rotates in another direction; after the rotation limit part rotates in the one direction through the pressure applied by the pressure gear, it rotates again in the other direction through the lifting limit part, thereby connecting with the pressure gear and locking the pressure gear.

[0030] On the other hand, the self-generating device provided further includes an auxiliary pressure-applying part, which provides pressure to the rotation limiting part that locks the pressure gear, so that the rotation limiting part rotates in the one direction, thereby releasing the locking of the rotation limiting part and the pressure gear, and the auxiliary pressure-applying part is arranged on the pressure module, and performs lifting and moving corresponding to the lifting and moving of the pressure module.

[0031] On the other hand, the self-generating device provided further includes a rotation guide portion, which moves corresponding to the movement of the pressure gear to control whether the auxiliary pressure portion provides pressure for the rotation limiting portion.

[0032] On the other hand, a self-generating device is provided, comprising:

[0033] a pressure module, which moves from a first position to a lower side by the pressure applied by the wheels to a local area of ​​the speed bump, and moves to the first position as the pressure is released;

[0034] A pressure gear, which moves toward the lower side through the pressure module;

[0035] A rotating gear meshes with the pressure gear and rotates along with the movement of the pressure gear;

[0036] a motor part that generates electricity through the rotational force of the rotating gear;

[0037] A limit module, which controls the position of the pressure gear,

[0038] a rotation guide connected to the pressure gear, which rotates counterclockwise from the second position to a given angle as the pressure gear moves downward, and resets to the second position as the pressure gear moves upward; and

[0039] The auxiliary pressure-applying part is arranged on the pressure-applying module, and applies pressure to the limiting module that locks the pressure-applying gear, so as to release the locking between the pressure-applying gear and the limiting module.

[0040] In the self-generating device provided on the other hand, a gear area is formed in the front lower area of ​​the pressure gear, and when the pressure gear moves downward or upward, the gear area meshes with the rotating gear to rotate the rotating gear.

[0041] In the self-generating device provided on the other hand, the pressure gear moves from an initial position toward a downward direction due to the pressure of the front wheels of the vehicle, and the pressure gear moves to the initial position due to the pressure of the rear wheels of the vehicle.

[0042] On the other hand, in the self-generating device provided, the pressure gear moves toward the downward direction due to the pressure of the front wheels of the vehicle and is locked in the limiting module, and the auxiliary pressure part provides pressure to the limiting module due to the pressure of the rear wheels of the vehicle, thereby releasing the lock between the pressure gear and the limiting module.

[0043] On the other hand, in the self-generating device provided, a first and a second protruding area are formed on one side of the rotating guide part. When the pressure gear moves toward the downward direction due to the pressure of the front wheel of the vehicle, the rotating guide part rotates to a given angle, so that the second protruding area rotates the auxiliary pressure part. When the front wheel pressure of the vehicle applied to the pressure module is released, the pressure module and the auxiliary pressure part rise, and a local area of ​​the auxiliary pressure part is inserted into the guide space between the first and the second protruding areas. When the pressure module moves toward the downward direction due to the pressure of the rear wheel of the vehicle, the local area of ​​the auxiliary pressure part moves along the guide space to provide pressure to the limiting module.

[0044] In the self-generating device provided on the other hand, when the rear wheel pressure of the vehicle applied to the pressure module is released, the pressure module moves to the initial position, and at the same time, the auxiliary pressure portion extends from the guide space and switches to the initial position.

[0048] Furthermore, the embodiment can solve the problem that it is difficult to maintain synchronization between gears due to extremely fast and repeated strong external forces from the front and rear wheels of the vehicle, and when the synchronization is destroyed, the device components are frequently damaged or destroyed due to the strong external forces.

[0049] Furthermore, the embodiment can enable a one-time virtual pressure limited to one vehicle to be applied to the self-generating device, thereby preventing the problem of gear damage caused by rapid and continuous strong external forces.

[0050] Furthermore, the embodiment can extend the rotation time of the gear until the time point when the next vehicle applies pressure again, thereby improving the charging efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0062] The present invention can be transformed in many ways and has many embodiments. Below, a specific embodiment is shown in the accompanying drawings and described in detail. The effects and features of the present invention and its implementation method can be clearly understood by referring to the accompanying drawings and the embodiments described in detail below. However, the present invention is not limited to the embodiments disclosed below, but can be implemented in various forms. In the following embodiments, the terms first, second, etc. do not have a limited meaning, but are used to distinguish one component from other components. Moreover, unless the context clearly indicates other meanings, the expression in the singular includes the expression in the plural. Moreover, the terms including or having mean having the features or components recorded in the specification, and do not pre-exclude one or more other features or components. Moreover, for the convenience of description, the components in the drawings can be enlarged or reduced in size. For example, for the convenience of description, the size and thickness of each component represented by the drawings are arbitrarily represented, and the present invention is not necessarily limited to the illustration of the drawings.

[0063] Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings. When describing with reference to the accompanying drawings, the same or corresponding components are given the same reference numerals and repeated description thereof will be omitted.

[0064] Figure 1 Schematic diagram of a self-generating device installed on a road where a means of transportation such as a vehicle, a motorcycle, or a bicycle travels in an embodiment of the present invention. Figure 2 It is a schematic diagram of a case where a self-generating device is buried on a sidewalk (a) and a case where a self-generating device is buried on a road (b), corresponding to a place where a speed bump is installed on the road.

[0065] refer to Figure 1 and Figure 2It can be seen that the self-generating device 100 described in the embodiment of the present invention can be set on a means of transportation such as a car 10 or a bicycle / motorcycle 70, that is, on a road where vehicles travel. In addition, the self-generating device 100 can be set on a sidewalk where people pass. The device can be buried in a place on the road or inside a speed bump 20 on the road.

[0066] The self-generating device 100 can generate electricity by utilizing the virtual pressure generated by the load applied to the ground by the means of transportation such as the automobile 10 or the bicycle / motorcycle 70 during driving. In the example, the virtual pressure generated by the wheel load of the automobile 10 or the bicycle / motorcycle 70 can be utilized to generate electricity. The main control 30 provided on the road can control the operation of the self-generating device 100. At least a portion of the electricity generated by the self-generating device 100 is stored, and at least a portion can be used as driving power for various display devices 40 on the sidewalk or road including street lamps. Among them, the display device 40 can be a road lamp, a light-emitting diode (LED) lamp in a tunnel, an electro-optical panel, a road sign, a signboard, a street lamp, a camera, etc., but is not limited thereto.

[0067] The self-generating device 100 may be composed of a plurality of devices. The plurality of self-generating devices 100 are aligned with each other in a direction perpendicular to the moving direction of the vehicle such as the automobile 10 or the bicycle / motorcycle 70, and are separated by a given distance. When the self-generating device 100 is buried on a road where vehicles pass, the spacing distance therebetween can be determined according to the distance between the left and right wheels of a normal vehicle.

[0068] At least a portion of the self-generating device 100 may be buried in the self-generating area 60 on the sidewalk. Also, the self-generating device 100 may be buried on the road. In various embodiments, the self-generating device 100 may be disposed on the speed bump 20. When a vehicle such as a car 10 or a bicycle / motorcycle 70 moves, virtual pressure is transmitted from the wheels to a portion of the speed bump 20, and the portion moves downward with the load and transmits the pressure to the self-generating device 100.

[0069] In addition, when the wheel receives pressure from the lower side, the local area 20p of the speed bump 20 moves downward, which is synchronized with the wheel's instantaneous movement downward. Moreover, the maximum movement distance of the wheel from the initial position of the pressure module 130 toward the lower side is substantially equal to the movement distance of the local area 20p toward the lower side and the instantaneous movement distance of the wheel toward the lower side.

[0070] Pressure is applied to the self-generating device 100, and is divided into primary pressure and secondary pressure at different time points. In the diagram, as the vehicle such as the car 10 or the bicycle / motorcycle 70 moves, the front wheel can form a primary pressure and the rear wheel can form a secondary pressure in the means of transportation. In addition, the rear wheel of the first means of transportation can form a primary pressure, and the front wheel of the second means of transportation that moves next in the first means of transportation can form a secondary pressure. In addition, the pedaling force of any one of the multiple people moving on the sidewalk forms a primary pressure, and the pedaling force of another person forms a secondary pressure.

[0071] Hereinafter, the self-generating device 100 will be described as being driven by the load of a vehicle, but is not limited thereto, and may be driven by other means of transportation or a load formed by humans moving on a sidewalk.

[0096] - Rotation guide 600

[0097] like Fig. 9 As shown, the power generation module 300 may further include a rotation guide portion 600. The rotation guide portion 600 may control whether the auxiliary pressure applying portion 400 described below provides pressure for the limit module 800.

In various embodiments, the lower area in front of the rotation guide part 600 can form a guide inclined surface 602 with a given angle inclined surface.

[0098] -Limiting module 800

[0099] like Fig.10 As shown, the power generation module 300 may further include a limit module 800. The limit module 800 may include a lifting limit part 820, which provides a rotational force that causes the rotation limit part 810 to rotate in another direction as the rotation limit part 810 and the rotation limit part 810 rotate in one direction. The rotation limit part 810 may include a first limit part 811 and a second limit part 812 connected to the first limit part 811. In various embodiments, the first and second limit parts 811 and 812 may be formed as an integral body with each other. In various embodiments, the first and second limit parts 811 and 812 are 'L' shaped as a whole. In various embodiments, a limit protrusion 813 may be formed on one side of the first limit part 811. In various embodiments, the upper surface of the limit protrusion 813 may have a limit protrusion inclined surface 813a of a given angle. In various embodiments, the surface of a local area on the upper surface of the second limit part 812 is 'U' shaped. The connection area of ​​the first and second limiting parts 811 and 812 can form a limiting fixing hole 814. The rotation limiting part 810 can be arranged on the front shell 111a through the limiting fixing hole 814. In various embodiments, the thread penetrates the limiting fixing hole 814 and is inserted into the inner side of the front shell 111a, so that the rotation limiting part 810 is arranged on the front shell 111a. The lifting limiting part 820 can be arranged on the rotation limiting part 810. In various embodiments, the lifting limiting part 820 can be arranged on the lower side of the second limiting part 812. In various embodiments, one side of the lifting limiting part 820 is arranged on the second limiting part 812, and the other side is arranged on the lower support part 113. The lifting limiting part 820 can be inserted into the lower support part 113 in a local area by applying an external force in the lower direction. In various embodiments, an elastic body can be provided between the lifting limiting part 820 and the lower support part 113. Therefore, the lifting and lowering limit part 820 can make the local area insert into the lower support part 113 by applying an external force toward the downward direction, and receive the upward force so as to be restored to the original position by the elastic force. The limit module 800 is rotated by a given angle with the limit fixing hole 814 as the center by the external force applied to the second limit part 812. When the limit module 800 is rotated by a given angle (clockwise direction) by the external force applied to the second limit part 812, the lifting and lowering limit part 820 can descend. When the external force applied to the second limit part 812 is released, the lifting and lowering limit part 820 performs an upward movement by the elastic force, so that the limit module 800 rotates by a given angle (counterclockwise). The auxiliary pressure part 400 described below can provide pressure to the top of the second limit part 812. The limiting protrusion 813 can be inserted Figure 8The limiting insertion slot 530 is shown. When the limiting module 800 is rotated by a given angle (clockwise) by the external force applied to the second limiting portion 812, the limiting protrusion 813 can extend from the limiting insertion slot 530. In addition, when the external force applied to the second limiting portion 812 is released, the lifting limiting portion 820 moves upward by elastic force, and at the same time, the limiting module 800 is rotated by a given angle (counterclockwise) so that the limiting protrusion 813 is inserted into the limiting insertion slot 530.

[0100] -Auxiliary pressure applying part 400

[0101] Refer to Fig.11 It can be known that the power generation module 300 may further include an auxiliary pressure-applying part 400. The auxiliary pressure-applying part 400 may include an auxiliary pressure-applying connecting part 410 and an auxiliary pressure-applying rotating part 420. The auxiliary pressure-applying connecting part 410 may be arranged on the pressure module 200. In various embodiments, the auxiliary pressure-applying connecting part 410 may be arranged on the lower side of the pressure module 200. One side of the auxiliary pressure-applying rotating part 420 may be arranged on the auxiliary pressure-applying connecting part 410. The auxiliary pressure-applying rotating part 420 can be rotated within a given angle range with the connection point of the auxiliary pressure-applying connecting part 410 as the center. As the pressure module 200 moves, the other side of the auxiliary pressure-applying rotating part 420 can apply pressure on the upper side of the second limiting part 812.

[0102] -First state to fifth state

[0103] 12 to 16 are diagrams showing various states of the self-generating device. Fig.12a is an oblique view of the self-generating device in the first state, Figure 12b is a front view of the self-generating device in the first state, Fig.13a is an oblique view of the self-generating device in the second state, Fig.13b is a front view of the self-generating device in the second state, Fig.14a is an oblique view of the self-generating device in the third state, Fig.14b is a front view of the self-generating device in the third state. Fig.15a is an oblique view of the self-generating device in the fourth state, Fig.15b is a front view of the self-generating device in the fourth state, Fig.16a is an oblique view of the self-generating device in the fifth state, Fig.16b It is a front view of the self-generating device in the fifth state.

[0104] 1) First state

[0105] like Fig.12a and Fig.13bAs shown, in the initial state of the self-generating device 100 as the first state, the pressure module 200 can be located at an initial position at a height of 1-1 (h11) from the lower support portion 113. In addition, in the pressure gear 500 connected to the inner support portion 112, according to the initial shape of the internal elastic body, the pressure gear 500 can be located at an initial position at a height of 2-1 (h21) from the lower support portion 113. In addition, the pressure gear 500 becomes a state of not contacting the rotating gear 700. In addition, the limit module 800, the auxiliary pressure portion 400 and the rotation guide portion 600 can be aligned with the initial position. In addition, a local area of ​​the guide inclined surface 602 of the rotation guide portion 600 can be adjacent to the rotation guide protrusion 111ap located between the pressure gear 500 and the rotation guide portion 600 or contact the rotation guide protrusion 111ap. The rotation guide protrusion 111ap may protrude from the inner side of the front housing 111a, but is not limited thereto, and the rear side of the rotation guide portion 600 may face the front side of the auxiliary pressure applying portion 400.

[0106] 2) Second state

[0107] Further, if Fig.13a and Fig.14bAs shown, when the wheel applies pressure to a local area 20p of the pressure module 200 as the vehicle moves, the self-generating device 100 can be converted into the second state. When the pressure module 200 moves a given distance toward the lower side, the first and second main reset parts 321 and 322 shrink. In addition, the height of the pressure module 200 from the lower support part 113 can become the 1-2 height (h12). In the process of moving toward the lower side of the pressure gear 500, the gear blade on the gear area 510 of the pressure gear 500 can be combined with the rotating gear 700 to rotate the rotating gear 700 in the first direction. Among them, the first direction can be a clockwise direction. In various embodiments, when the pressure module 200 moves so that the height from the lower support part 113 becomes the 1-2 height (h12), the height of the pressure gear 500 from the lower support part 113 also becomes the 2-2 height (h22). The gear blade on the gear area 510 of the pressure gear 500 and the gear of the rotating gear 700 can be released, so that the rotating gear 700 can keep rotating a given number of revolutions in the first direction by the residual rotational force, and can stop rotating after a given moment by the impedance force of the motor part 900. The rotating guide part 600 connected to the pressure gear 500 can move toward the lower side together with the pressure gear 500. And the rotating guide part 600 can rotate a first angle through the rotating guide protrusion 111ap located between the pressure gear 500 and the rotating guide part 600. That is, as the lower side of the rotating guide part 600 moves, the rotating guide protrusion 111ap of the rotating guide part 600 can contact the guiding inclined surface 602, move along the guiding inclined surface 602 and the front of the rotating guide part 600, and rotate the rotating guide part 600 by the first angle in the counterclockwise direction. Furthermore, as the rotation guide portion 600 rotates at a first angle in the counterclockwise direction, the second protruding area 620 of the rotation guide portion 600 contacts the end of the auxiliary pressure rotating portion 420, and the end of the auxiliary pressure rotating portion 420 applies pressure toward the rear direction of the rotation guide portion 600, so that the rotation guide portion 600 rotates at a given angle in the counterclockwise direction. Furthermore, as the pressure gear 500 moves toward the lower side, at least a partial area of ​​the lower surface of the pressure gear 500 contacts the upper surface of the limiting protrusion 813, that is, the limiting protruding inclined surface 813a, and moves along the limiting protruding inclined surface 813a. Furthermore, as the pressure gear 500 presses the limiting protruding inclined surface 813a, it can move along the limiting protruding inclined surface 813a, and at the same time, the rotation limiting portion 810 is rotated at a given angle in the clockwise direction. Furthermore, as the rotation limiting part 810 rotates a given angle, pressure is transmitted to the lifting limiting part 820 connected to the rotation limiting part 810 , and the lifting limiting part 820 is subjected to a reaction force that is transferred to the initial position.Furthermore, as the height of the pressure gear 500 reaches the 2-2 height (h22), the rotation limiter 810 rotates counterclockwise due to the reaction force applied to the lifting limiter 820, thereby inserting the limiter protrusion 813 into the limiter insertion groove 530.

[0108] In addition, 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).

[0109] 3) The third state

[0110] Further, if Fig.14a and Fig.14b As shown, when the pressure applied to the pressure module 200 is released, as the contracted first and second main reset parts 321 and 322 are converted toward the initial position, the pressure module 200 can be converted to the initial position, that is, the 1-1 height (h11). As the pressure module 200 rises, the auxiliary pressure part 400 provided in the pressure module 200 will rise. The auxiliary pressure part 400 rises, and the end of the auxiliary pressure rotating part 420 moves along the second protruding area 620 of the rotation guide part 600. At the same time, as the contact between the auxiliary pressure rotating part 420 and the second protruding area 620 is released, the auxiliary pressure rotating part 420 rotates in the clockwise direction to a given angle and becomes the initial position of the first state. In addition, the local lower area of ​​the auxiliary pressure rotating part 420 is inserted into the guide space 601 of the rotation guide part 600. At this time, the pressure gear 500 remains connected to the limiting module 800, and therefore, the height of the pressure gear 500 remains at the 2-2 height (h22).

[0111] 4) Fourth state

[0112] Further, refer to Fig.15a and Fig.15b As shown, when the wheel applies pressure to the pressure module 200 for the second time, the pressure module 200 is converted from the 1-1 height (h11) to the 1-2 height (h12), thereby shrinking the 1st and 2nd main reset parts 321 and 322. In addition, as the pressure module 200 moves downward, the auxiliary pressure rotating part 420 moves downward. At this time, the area of ​​the auxiliary pressure rotating part 420 inserted into the guide space 601 of the rotation guide part 600 is increased. The height of the pressure module 200 becomes the 1-2 height (h12), and then, the auxiliary pressure rotating part 420 provides pressure toward the downward direction for the upper side of the second limiting part 812, thereby, the rotation limiting part 810 is rotated again in the clockwise direction by a given angle. At this time, the limiting protrusion 813 extends from the limiting insertion groove 530, releasing the connection between the pressure gear 500 and the limiting module 800.

[0113] 5) Fifth state

[0114] Further, if Fig.16a and Fig.16b As shown, when the wheel pressure is released, the contracted first and second main reset parts 321 and 322 are expanded and converted to the initial position, thereby, the pressure module 200 can rise and move, and convert from the 1-2 height (h12) to the 1-1 height (h11). In addition, the pressure gear 500 can also rise and move, and convert from the 2-1 height (h21) to the 2-2 height (h22). As the pressure module 200 rises, the auxiliary pressure part 400 also rises, and the pressure applied by the auxiliary pressure rotating part 420 on the second limit part 812 is released, and then the rotation limit part 810 rotates counterclockwise to a given angle to facilitate conversion to the initial position. In addition, the auxiliary pressure rotating part 420 rises and extends from the guide space 601 of the rotation guide part 600, and the auxiliary pressure rotating part 420 faces the back of the rotation guide part 600. And, as the pressing gear 500 rises, the front surface of the rotation guide part 600 contacts the rotation guide protrusion 111ap and rotates in the clockwise direction at a given angle, thereby returning to the position as in the first state.

[0115] At this time, the lower side of the pressure module 200 is provided with a pressure module groove 201, so when the pressure module 200 performs a descending and ascending motion, the moving distance is longer than the moving distance of the rotating guide part 600 caused by the descending and ascending motion of the pressure gear 500. Therefore, when the pressure module 200 is converted from the fourth state to the fifth state, it rises to the auxiliary pressure part 400 together with the rotating guide part 600, but as the pressure module 200 becomes the 1-1 height (h11), the auxiliary pressure rotating part 420 is completely extended from the guide space 601 of the rotating guide part 600, so that the auxiliary pressure rotating part 420 faces the back of the rotating guide part 600, and the auxiliary pressure rotating part 420 is converted to the initial position equivalent to the first state.

[0116] When the pressure gear 500 rises, the auxiliary rotating gear 730 rotates in the opposite direction to further generate electricity. In addition, as the pressure gear 500 is converted to the initial position, the gear connection between the pressure gear 500 and the auxiliary rotating gear 730 is released. At this time, the residual rotation force of the auxiliary rotating gear 730 can be naturally eliminated, further increasing the power generation.

[0117] In addition, the primary pressure is the pressure applied by the front wheels of the vehicle, and the secondary pressure is the pressure applied by the rear wheels of the vehicle. In various embodiments, the primary pressure is the pressure applied by the rear wheels of a first vehicle, and the secondary pressure is the pressure applied by the front wheels of a second vehicle different from the first vehicle.

[0118] In addition, if Figure 3bAs shown, the inner support portion 112 of the self-generating device 100 according to various embodiments of the present invention may be combined with the outer housing 111 .

[0119] The inner support portion 112 has a covering function for the outer shell 111 and can cover the accommodating space 110s. The first and second main support portions 311 and 312 can be arranged on the inner support portion 112. In addition, the first main reset portion 321 connects the first main support portion 311 with the pressure module 200, and the second main reset portion 322 connects the second main support portion 312 with the pressure module 200. The external force applied to the pressure module 200 and the release of the external force can change the distance between the bottom of the pressure module 200 and the front of the inner support portion 112. The inner support portion 112 has a covering function for the outer shell 111 and can cover the accommodating space 110s, thereby preventing pollutants from flowing into the accommodating space 110s.

[0120] Figures 17 to 21 It is an internal schematic diagram of the self-generating device shown in FIG3 , and the description of the working mode is the same as that of the self-generating device shown in FIG3 .

[0121] 1) First state

[0122] like Fig.17 As shown, in the first state, the pressure module 200, the auxiliary pressure part 400, the pressure gear 500, the rotation guide part 600, and the limit module 800 constituting the self-generating device 100 may have Fig.17 Initial position shown.

[0123] 2) Second state

[0124] As shown in FIG18 , as the vehicle moves, when the wheel applies pressure to the pressure module 200 once, the self-generating device 100 can be converted into the second state. The pressure module 200 moves a given distance toward the lower side, so that the first and second main reset parts 321 and 322 are contracted. As it moves toward the lower side of the pressure gear 500, the rotating gear 700 can be rotated by the pressure gear 500. The rotating guide part 600 connected to the pressure gear 500 can move toward the lower side together with the pressure gear 500. And, through the rotating guide protrusion 111ap located between the pressure gear 500 and the rotating guide part 600, the rotating guide part 600 can rotate by a first angle. And, as it rotates to the first angle in the counterclockwise direction of the rotating guide part 600, a force is applied to the end of the auxiliary pressure rotating part 420 toward the rear direction of the rotating guide part 600, so that the rotating guide part 600 rotates to a given angle in the counterclockwise direction. Furthermore, as the pressure gear 500 moves toward the lower side, at least a partial area below the pressure gear 500 contacts the upper surface of the limiting protrusion 813, that is, the limiting protruding inclined surface 813a, thereby moving along the limiting protruding inclined surface 813a. Furthermore, as the pressure gear 500 applies pressure to the limiting protruding inclined surface 813a, it moves along the limiting protruding inclined surface 813a, thereby causing the rotation limiting portion 810 to rotate in the clockwise direction by a given angle, and the contracted lifting elastic body 821 inside the lifting limiting portion 820 is contracted. Furthermore, through the restoring force of the lifting elastic body 821, the rotation limiting portion 810 rotates in the counterclockwise direction to a given angle, thereby causing the limiting protrusion 813 to be inserted into the limiting insertion groove 530. Therefore, the pressure gear elastic body 590 disposed inside the pressure gear 500 and connected to the inner support portion 112 extends, thereby having an elastic force to be contracted, but the pressure gear 500 is locked by the limiting module 800 to maintain the current position.

[0125] 3) The third state

[0126] like Fig.19 As shown, when the pressure applied to the pressure module 200 is released, the pressure module 200 can be moved to the initial position of the first state by the resetting force of the contracted first and second main resetting parts 321 and 322. In addition, the auxiliary pressure part 400 rises together with the pressure module 200. In addition, as the contact between the auxiliary pressure rotating part 420 and the second protruding area 620 is released, the auxiliary pressure rotating part 420 rotates clockwise to a given angle and becomes the initial position of the first state. In addition, the local lower area of ​​the auxiliary pressure rotating part 420 is inserted into the guide space 601 of the rotation guide part 600.

[0127] 4) Fourth state

[0128] Further, if Fig. 20As shown, when the wheel applies pressure to the pressure module 200 for the second time, the pressure module 200 descends again, and the first and second main reset parts 321 and 322 are retracted. In addition, the auxiliary pressure rotating part 420 moves toward the lower side together with the pressure module 200. At this time, the auxiliary pressure rotating part 420 is further inserted into the guide space 601 of the rotation guide part 600. In addition, the auxiliary pressure rotating part 420 provides pressure to the upper side of the second limiting part 812 along the lower side, thereby, the rotation limiting part 810 is rotated to a given angle in the clockwise direction again, thereby, the lifting elastic body 821 is retracted. At this time, the limiting protrusion 813 extends from the limiting insertion groove 530, releasing the connection between the pressure gear 500 and the limiting module 800. Therefore, the pressure module 200 is subjected to the force of resetting to the initial position in the first state through the elastic force of the pressure gear elastic body 590.

[0129] 5) Fifth state

[0130] like Fig.21 As shown, when the pressure of the wheel is released, the retracted first and second main reset parts 321 and 322 are converted to the initial position by the reset force, thereby the pressure module 200 moves upward. The auxiliary pressure part 400 rises together with the pressure module 200. In addition, the pressure applied by the auxiliary pressure rotating part 420 on the second limit part 812 is released. In addition, in order to convert to the initial position by the elastic force of the lifting elastic body 821, the rotation limit part 810 rotates to a given angle in the counterclockwise direction. In addition, while the auxiliary pressure rotating part 420 rises, the guide space 601 of the rotation guide part 600 extends, and the auxiliary pressure rotating part 420 faces the back of the rotation guide part 600. In addition, as the pressure gear 500 rises, the front of the rotation guide part 600 contacts the rotation guide protrusion 111ap, rotates to a given angle in the clockwise direction, and then resets to the position as in the first state.
