Since the 21st century, people's living standards have continued to improve, and the number of motor vehicles has also continued to increase. In order to avoid traffic accidents, many speed bumps are set up at many highway intersections, industrial and mining enterprises, schools, residential entrances, and other sections where vehicles need to slow down. A large amount of energy will be generated when passing through the speed bumps. In order to utilize this green energy and avoid risks, both domestic and foreign countries have conducted beneficial explorations.

[0040] In the present invention, the transmission pulley 306 is connected to an external rotating power generation device through a belt. The external rotating power generation device in the present invention is a known technology that has been disclosed and widely used in daily life.

[0041] Working principle and use process of the present invention: When the present invention is used, two sets of energy conversion components 300 are arranged between the parking assistance ramp component 100 and the ramp mounting seat component 200. The parking assistance ramp component 100, the ramp mounting seat component 200 and the energy conversion component 300 form a complete set of parking assistance ramp units. A complete set of parking assistance ramp units are installed in the parking platform 401 on the right rear side of the parking platform 401. A row of multiple complete sets of parking assistance ramp units are arranged on the right rear side of the parking platform component 400. An auxiliary arc slope 102 is fixedly arranged on the top of one side of the side parking assistance ramp 101. A parking calibration structure when parking is formed between the two auxiliary arc slopes 102 on the two side parking assistance ramps 101 arranged opposite to each other. In actual use, when reversing into a garage on the right, the driver drives the vehicle onto the parking platform assembly 400. If the vehicle presses against the auxiliary arc slope 102, the vehicle will form a certain inclination at this time, and the driver will feel it. In this way, the driver is reminded that the vehicle is parked too close to the side, and can be appropriately moved to the middle of the parking platform assembly 400. At the same time, it can avoid scratching the side vehicles due to parking too close to the side. At the same time, a ramp mounting seat assembly 200 is installed below the parking auxiliary ramp assembly 100. During installation, the main shaft frame rod 103 slides back and forth up and down in the central shaft sleeve seat 205, and the sliding piston 106 slides back and forth up and down in the piston seat sleeve 203. The parking auxiliary ramp assembly 100 forms a parking auxiliary ramp with an up and down reciprocating motion above the ramp mounting seat assembly 200. The first energy conversion gear 301 and the second energy conversion gear 302 rotate on the lateral support arm plate 204 on one side through the conversion gear main shaft rod 305 and the bearing seat, and the first energy conversion gear 301 and the second energy conversion gear 302 are meshed with each other. A groove is provided at the bottom of the sliding piston 106, and a closed structure is formed at the top of the first guide arm plate 303 and the second guide arm plate 304. The closed arm bodies at the top of the first guide arm plate 303 and the second guide arm plate 304 rotate in the groove at the bottom of the sliding piston 106. When the vehicle is parked, the side parking assist ramp 101 is subjected to the pressure of the vehicle to move up and down. At this time, the sliding piston 106 drives the top arms of the first guide arm plate 303 and the second guide arm plate 304 to move up and down. The up and down movement of the bottom arm bodies of the first guide arm plate 303 and the second guide arm plate 304 form a driving structure in which the first energy conversion gear 301 and the second energy conversion gear 302 rotate in opposite directions. The transmission pulley 306 is connected to an external rotating power generation device through a belt. In this way, the up and down movement of the parking assist ramp assembly 100 is converted into a unidirectional rotation structure of the transmission pulley 306. At this time, the transmission pulley 306 is connected to an external rotating power generation device through a belt. Through this driving structure, power generation is achieved, thereby realizing energy recovery and utilization. At the same time, the reciprocating slide block 208 reciprocates on the end rod body of the transverse main frame rod 209. Through the push of the reset spring 213, the two reciprocating slide blocks 208 are in a naturally close structure.In this way, in actual use, the main shaft frame rod 103 is reset and pushed by the reset spring 213, the auxiliary support arm plate 206 and the main support arm plate 207, so that the parking assist ramp assembly 100 can be quickly reset each time it is pressed down, thereby preparing for the next pressing down and energy generation recovery action.

[0042] The present invention is applicable to another parking environment, that is, an environment in which a vehicle is assisted to go uphill from the right rear side, such as Figure 8 When assisting uphill from the right rear side, this device can assist in lifting the right rear wheel of the vehicle, thereby facilitating subsequent uphill.

[0043] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
