[0029] The first layer and the second layer transmission structure are fixedly installed through the positioning grooves on the shell 21 to realize the stable engagement between the parts, guarantee the power transmission efficiency, and realize the one-way rotation of the intermediate gear 4 so as to guarantee the one-way continuous rotation of the power generation unit 16 and improve the output performance.

[0030] The shell 21 is installed by cooperating with the rack 12 to realize the transmission of external excitation power, and spring limiting holes I21-3 and spring limiting holes II21-5 are designed on both sides of the shell 21 to realize the installation of the spring 11 and the reset function after external excitation; the power transmission of the external excitation of the rack 12 is realized by the intermeshing of the side plate gear I6 and the side plate gear II18 installed on both sides with the rack of the rack 12 to realize the conversion of linear motion in the vertical direction to rotary motion, the side plate gear I6 is fixed and installed through the cooperation of the shaft hole between the side plate positioning hole I21-2 on the shell 21 and the side plate positioning hole 19-1 on the side plate 19 and the side plate positioning shaft I7, and the side plate 19 is fixedly connected with the bottom plate 26 by adhesion or welding.

[0031] The side plate gear I6 and the rack I5 are engaged, the side plate gear II18 and the rack II20 are engaged, and the power transmission is realized; the rack I6 and the rack II20 both have tooth profile distribution in the vertical direction and the horizontal direction, and are arranged in opposite directions to realize the function of bidirectional transmission; the horizontal teeth of the rack I5 and the rack II20 are engaged with the large gear I1, and the vertical teeth are engaged with the side plate gear I6 and the side plate gear II18, so as to transmit power to the gear train and further drive the movement of the power generation unit 16.

[0033] The power transmission route is as follows: when the vehicle passes through the deceleration zone, the downward pressure of the vehicle on the rack frame 12 is first transmitted to the side plate gears I6 and II 18 on both sides, then transmitted to the racks I5 and II 20 by the side plate gears I6 and II 18 to change the transmission direction, the linear motion of the racks I5 and II 20 drives the two identical large gears I1 engaged therewith to rotate in opposite directions, the two identical large gears I1 are engaged with the pinions I25 and II 24 respectively and in turn drive the pinions to rotate in opposite directions, the two identical large gears II 8 rotate synchronously with the pinions I25 and II 24 respectively and also rotate in opposite directions, since the two large gears II 8 are connected with the pinion fixed shaft I23 and the pinion fixed shaft II 9 through the one-way bearings I22 and II 10 respectively, therefore the two large gears II 8 always keep one-way rotation of the intermediate gear 4 driven by one-way torque transmission and the other does not transmit torque; after the vehicle passes through the deceleration zone, the transmission components all perform resetting motion under the action of the spring 11, at this time the two large gears II 8 still keep the same direction of torque transmission, so that the rotating power generation unit 16-3 continuously rotates in one direction, therefore the two-way transmission mechanism is realized through the gear and rack and the one-way bearing.

[0034] The two-way transmission structure is covered by the deceleration zone shell 13 and integrated in a deceleration zone, when the vehicle passes through the deceleration zone, the mechanical energy of the vehicle can be collected efficiently, and the mechanical energy is converted into electrical energy output by the friction nanogenerator, the infrared LED lamp is driven by the electrical energy output, the signal of the infrared LED lamp is received and detected to realize self-powered vehicle flow detection of the intelligent deceleration zone, at the same time, the traffic signal lamp control time is optimized and trained by using the SUMO platform and combining the deep Q network (DQN) model of reinforcement learning, the trained model realizes dynamic regulation of the best time of the traffic signal lamp to realize dynamic adjustment of the traffic flow, so as to relieve traffic congestion and improve the road traffic capacity, thus forming a complete working cycle of the intelligent deceleration zone from vehicle mechanical energy collection to friction nanogenerator electrical energy output, and realizing self-powered vehicle flow detection and time optimization of the traffic signal lamp to realize dynamic traffic flow regulation by combining the SUMO simulation platform.

[0035] In summary, the two-way transmission structure is realized by the design of the gear and rack structure, on this basis, the friction nanogenerator with contact-sliding-separation mode is designed to realize efficient power transmission and energy collection, the intelligent deceleration zone based on the multifunctional friction nanogenerator has the advantages of self-powered vehicle flow detection, high integration, high structural stability and the like, and the deep Q network (DQN) model of reinforcement learning is combined to realize dynamic control of the traffic signal lamp timing, the present application has important significance for the development and construction of intelligent transportation and smart city, and can be used as a reference scheme for the development of intelligent deceleration zone.

[0037] The self-powered intelligent deceleration strip based on the multifunctional friction nanogenerator, wherein the gears of the bidirectional transmission mechanism are meshed with each other, the linear displacement of the rack in the vertical direction generated by the external load is converted into the rotary motion of the gear train in the horizontal direction, the continuous one-way rotation of the power generation unit is converted from the bidirectional rotary motion through the reverse arrangement of the bidirectional rack, the meshing of the gears and the action of the one-way bearing, the linear motion part of the power generation unit performs the linear motion in the vertical direction synchronously with the rack frame, and therefore the contact-sliding-separation motion mode of the power generation unit is realized, and the energy output is improved.

[0038] The rack frame is reset by the restoring force of the spring, the power transmission of the gear and the rack is still performed in the stroke of the vehicle passing through the deceleration strip without the action of the external load, the operation time of the rotary power generation unit is further improved, and therefore the output performance is improved.

[0039] In summary, the multifunctional friction nanogenerator adopting the bidirectional transmission mechanism and the contact-sliding-separation motion mode realizes efficient power transmission and energy harvesting, realizes self-powered vehicle flow detection, further improves the integration and passivity of the intelligent deceleration strip, and promotes the development of the intelligent traffic system.
