This technology not only provides energy for roadside traffic facilities such as lighting and monitoring facilities, but also effectively solves the problem of inconvenient power supply in remote areas. In addition, piezoelectric road surfaces can also derive a series of intelligent traffic systems, such as piezoelectric light-emitting road warning and guidance systems, piezoelectric heating road deicing and ice melting systems, piezoelectric energy-powered charging pile systems, and piezoelectric energy-powered non-stop charging systems.

Meanwhile, the number of the lighting plates 217 can be flexibly increased or reduced according to actual lighting requirements. Different lighting requirements are met.

[0028] Please refer to Figures 2-4 In the embodiment, a plurality of limiting grooves are provided with a plurality of limiting plates 219 in the interiors. The lighting plates 217 are arranged in close contact with the limiting grooves through the limiting plates 219. The inner walls of the plurality of lighting plates 217 are provided with microwave inductors. The lighting plates 217 are sleeved with protection frames 220 on the outer sides. Screws are arranged at the outer end corners of the protection frames 220. The protection frames 220 are threadedly fixed with the roadbed frame 1 through the screws. The protection frames 220 are used to protect the lighting plates 217 and the joints. The safety risks, such as short circuit and electric shock, of the lighting plates 217 and the joints caused by water vapor are prevented. The safe operation of the lighting plates 217 is ensured. The model of the microwave inductor is WB-4002. Two groups of positioning blocks 223 are welded at the two ends of the roadbed frame 1.

The connection between the roadbed frame 1 and the ground is ensured to be more firm. Displacement or damage caused by pressure generated when vehicles pass through is reduced. The stability of the whole device is improved.

[0029] In the work, first of all, the roadbed frame 1 is connected with the ground by the positioning block 223 and the limiting screw 222 at both ends, and then the roadbed frame 1 is inserted into the ground of the charging parking space, so that the connection between the roadbed frame 1 and the ground is more firm, and the displacement caused by the pressure generated by the vehicle passing through is reduced. After the positioning of the roadbed frame 1, according to the lighting demand of the charging parking space, the lighting plate 217 is installed in the limiting groove and is electrically connected with the shunt rod 221 and the current transmission rod 216, so that the electric quantity generated by the subsequent pressure can be uniformly distributed to each lighting plate 217, and each group of lighting plates 217 can obtain stable power supply. At the same time, according to the actual lighting demand, the number of lighting plates 217 can be increased or decreased flexibly, which can meet the different lighting demands of the charging parking space. After the insertion and positioning of the lighting plate 217, the protection frame 220 is fixed with the roadbed frame 1 by a plurality of bolts, so as to protect the connection between the lighting plate 217 and the shunt rod 221 and the current transmission rod 216, prevent the water vapor from causing short circuit or electric shock and other safety risks to the lighting plate 217 and the joint, and ensure the safe operation of the lighting plate 217. After the installation of the lighting plate 217 according to the demand, when the vehicle passes through the parking space, the two rear wheels of the vehicle preferentially roll and press the front pressing plate 201, the front pressing plate 201 is connected with the two groups of main racks 203 to move linearly along the outer end of the main gear 204, and then the main gear 204 rotates with the rotating rod 205 to trigger the generator mechanism of the power generation module 215 to generate electricity by pressing and rotating power.

[0030] When the rear wheel of the vehicle moves to the upper end of the main plate 206 and rolls, the front pressing plate 201 lacks the downward force on its surface, and the front pressing plate 201 is repelled by the repulsive force of the connecting spring. When the front pressing plate 201 is repelled by the elastic force, the front pressing plate 201 drives the main rack 203 to make a second linear motion along the outer end of the main gear 204 to generate electricity again. When the rear wheel rolls on the main plate 206, the main plate 206 is connected to the middle rack 209 to make a linear motion along the outer end of the middle gear 210, driving the rotating rod 205 to connect the power generation module 215 to generate electricity. When the vehicle rear wheel rolls on the rear pressing plate 211, the main plate 206 is not subjected to downward pressure, and the main plate 206 is reset by the repulsive force of the supporting spring 208 to generate electricity. When the rear pressing plate 211 is subjected to pressure, the rear pressing plate 211 is combined with the rear rack 213 to make a linear motion along the outer end of the rear gear 214, driving the rotating rod 205 to generate electricity. The vehicle rolls on the front pressing plate 201, the main plate 206 and the rear pressing plate 211 in the charging position in turn to generate electricity multiple times. When the front pressing plate 201, the main plate 206 and the rear pressing plate 211 are subjected to pressure, the pressing plate subjected to pressure is subjected to linear motion and enters the neutral position, avoiding the damage of the gear and the rack when the pressing plates are subjected to pressure at the same time, ensuring the stable downward pressing and generating work of the pressing plates, fully utilizing the pressure of the vehicle on the road, triggering the generator mechanism of the power generation module 215 multiple times, collecting more energy and increasing the total power generation, so that different vehicles can touch the pressing plates at different positions and respond effectively to generate electricity.

[0031] At the same time, the microwave sensor senses the movement state of the object inside the lighting plate 217. When the object moves, the lighting plate 217 uses the stored power in the battery to perform lighting work. When there is no object movement, the microwave sensor controls the lighting plate 217 to be turned off, ensuring flexible power generation of the device in multiple situations, providing longer lighting time, reducing dependence on external power supply, evenly distributing electrical energy to each lighting plate 217, and ensuring that each group of lighting plates 217 can obtain stable power supply to meet different lighting needs.

[0032] Through the above steps, by the press plate 201 when the vehicle passes, combined with the meshing effect of the rack and pinion drive rotating rod 205 rotation by the power generation module 215 to generate electricity, along the charging parking after the press plate 201, the vehicle rear wheel pressure into the main plate 206 upper end, to the inside of the parking space when moving through the rolling back pressure plate 211, in turn, rolling front plate 201, main plate 206 and back plate 211 to generate electricity, make full use of the vehicle on the road pressure, multiple trigger generator mechanism of power generation module 215, collect more energy, increase the total power generation, so that different vehicles in different speed or parking charging parking distance is different, can touch the different position of the plate effective response and power generation work, ensure that the device in multiple cases of flexible power generation, provide longer time lighting, reduce the dependence on external power supply, improve the utilization efficiency of energy, and use the connecting spring and support spring 208 respectively support front plate 201, main plate 206 and back plate 211 in the rolling into the back can bounce in time, facilitate the subsequent continuous rolling power generation, evenly distribute the electrical energy to each lighting plate 217, ensure that each group of lighting plate 217 can obtain stable power supply, meet the different lighting needs.
