The top plate 1110 and the mounting shell constitute a box, but the top plate 1110 is not in contact with the mounting shell. One side of the mounting shell is an open side, and the top plate 1110 is located on the open side. Four linear bearings 1120 are provided, and the upper end surfaces of the linear bearings 1120(1), 1120(2), 1120(3), and 1120(4) are fixedly installed on the top plate 1110.

The square permanent magnets 1141 are embedded and fixed on the driving magnetic strip 1140 in a staggered magnetic pole distribution manner.

[0039] In this embodiment, when the driving magnetic strip 1140 slides in a certain direction, it drives the connecting rods 1142(1) and 1142(2) to move around the fulcrum shafts 1143(1) and 1143(2) as fulcrums. Under the driving of the connecting rods 1142(1) and 1142(2), the driven magnetic strip 1144 slides relative to the driven magnetic strip guide rail 1130, and the sliding direction of the driven magnetic strip 1144 is opposite to that of the driving magnetic strip 1140.

[0040] In this embodiment, as shown in Figure 5 , Figure 6 The transmission and power generation module 1200 includes a sealed box, an electromagnetic power generation assembly, and a gear transmission assembly. The electromagnetic power generation assembly includes a rotating magnet disc 1230, a circular permanent magnet 1231, and a coil 1240. The gear transmission assembly includes a driving gear 1210, a reversing gear 1212, a transmission shaft 1213, a frequency increasing gear 1214, a transmission shaft 1215, a transmission gear 1216, a one-way bearing 1217, a driving support shaft 1218, a magnet disc gear 1219, a frequency increasing gear 1220, a transmission shaft 1221, a one-way bearing 1222, and a transmission gear 1223. The driving gear 1210 and the reversing gear 1212 are located outside the sealed box, and the remaining components are located inside the sealed box. In this embodiment, the magnetic force transmission assembly is composed of a driving magnetic strip 1140, a driven magnetic strip 1144, a connecting rod 1142, the driving gear 1210, and a square permanent magnet 1211, which is used for magnetic force transmission, i.e., converting the sliding of the wheel driving module into the rotation of the gear.

[0041] In this embodiment, the driving support shaft 1218, the transmission shaft 1213, the transmission shaft 1215, and the transmission shaft 1221 are fixedly installed on the bottom plate 1241 of the sealed box and the top plate of the sealed box through bearings. The driving gear 1210 and the magnet disc gear 1219 are installed on the driving support shaft 1218. The reversing gear 1212 is installed on the transmission shaft 1213. The frequency increasing gear 1214 and the transmission gear 1216 are installed on the transmission shaft 1215. The frequency increasing gear 1220 and the transmission gear 1223 are installed on the transmission shaft 1221. The driving gear 1210 rotates under the drive of the magnetic torque, driving the reversing gear 1212 and the frequency increasing gear 1220. The reversing gear 1212 drives the frequency increasing gear 1214, which drives the transmission shaft 1215. The frequency increasing gear 1220 drives the transmission shaft 1221. The transmission shaft 1215 drives the transmission gear 1216, and the transmission shaft 1221 drives the transmission gear 1223. The magnet disc gear 1219 is driven by the transmission gear 1216 and the transmission gear 1223. The number of teeth of the frequency increasing gears 1214 and 1220 is less than that of the driving gear 1210 and the reversing gear 1212. The inner ring of the one-way bearing 1217 is installed on the transmission shaft 1215, and the outer ring is installed on the transmission gear 1216. The inner ring of the one-way bearing 1222 is installed on the transmission shaft 1221, and the outer ring is installed on the transmission gear 1223. The transmission gears 1216 and 1223 can only rotate in one direction. The transmission gear 1216 and the transmission gear 1223 rotate in the same direction. The rotating magnet disc 1230 is installed on the driving support shaft 1218 and is driven by the driving support shaft 1218.

[0042] In this embodiment, the square permanent magnets 1211 are symmetrically inlaid on the driving gear 1210 with staggered magnetic poles. The circular permanent magnets 1231 are arrayed and inlaid on the rotating magnet disc 1230 in a ring-shaped distribution with staggered magnetic poles, with opposite magnetic poles of adjacent magnets. The coils 1240 are arrayed and inlaid on the bottom plate 1241 of the sealed box in a ring-shaped distribution. The circular permanent magnets 1231 correspond to the coils 1240 one by one, and the lead wires of the coils 1240 are connected to external circuits. The bottom plate 1241 of the sealed box is installed on the mounting shell 1310.

[0043] As shown in Figure 8 The sliding magnetic coupling vehicle-road energy harvesting device of the application is applied to the application schematic diagram of vehicle-road energy harvesting. The sliding magnetic coupling vehicle-road energy harvesting device 1000 is embedded in the roadbed. The top plate 1110 is flush with the road surface, and the top plate 1110 slides after the wheels exert rolling excitation thereon.

[0044] The working principle of the application is as follows:

[0045] When the vehicle drives through the sliding magnetic coupling vehicle-road energy harvester 1000, the top plate 1110 of the wheel driving module 1100 slides in the direction opposite to the driving direction of the vehicle under the action of the friction force generated by the wheel rolling. The linear bearing 1120 fixedly installed on the top plate 1110 slides on the slide rail 1311. The reset spring 1312 installed on the slide rail 1311 limits and resets the movement of the linear bearing 1120. It is worth noting that, after the vehicle drives through and the wheels exert rolling excitation on the sliding magnetic coupling vehicle-road energy harvesting device 1000 once, the top plate 1110 and the linear bearing 1120 slide in a direction, and under the action of the reset spring 1312, the linear bearing 1120 drives the top plate 1130 to reciprocate on the slide rail. The driving magnetic strip 1140 is fixedly installed on the top plate 1110, and when the driving magnetic strip 1140 moves in a direction along with the top plate 1110, it drives the connecting rod 1142 to move around the fulcrum shaft 1143, and the driven magnetic strip 1144 slides on the driven magnetic strip guide rail 1130 under the driving of the connecting rod 1142. The movement direction of the driven magnetic strip 1144 is opposite to that of the driving magnetic strip 1140. It is worth noting that the fulcrum shaft 1143 is installed on the connecting rod 1142 close to the driving magnetic strip 1140, which enlarges the sliding distance of the driven magnetic strip 1144 and is beneficial to improving the energy conversion efficiency and output power.

[0046] Square permanent magnets 1141 are embedded in the driving magnetic strip 1140 and the driven magnetic strip 1144 in a pole-interleaved manner, corresponding to the square permanent magnets 1211 embedded in the driving gear 1210 in a pole-interleaved manner. In the initial condition that the sliding magnetic coupling vehicle-road energy harvesting device 1000 is not excited by the rolling of the wheels, the square permanent magnets 1141 are attracted to the square permanent magnets 1211. When the driving magnetic strip 1140 moves in a certain direction and the driven magnetic strip 1144 moves in the opposite direction, the relative positions of the square permanent magnets 1141 and the square permanent magnets 1211 change, the square permanent magnets 1141 repel the square permanent magnets 1241, and a rotating torque is generated on the driving gear 1210. Under the action of the rotating torque, the driving gear 1210 rotates at a high speed. It is worth noting that the square permanent magnets 1141 embedded in the driving magnetic strip 1140 and the driven magnetic strip 1144 are arranged in a non-equidistant manner, which amplifies the magnetic torque acting on the driving gear 1210 and significantly increases the rotating torque. When there is no vehicle passing through, as the rotating speed of the driving gear 1210 decreases, the top plate 1110, the driving magnetic strip 1140, the connecting rod 1142, and the driven magnetic strip 1144 are reset to the initial position under the action of the reset torque generated by the square permanent magnets 1141 and the square permanent magnets 1211 on the driving gear 1210. The square permanent magnets 1141 and the square permanent magnets 1211 are attracted to each other, waiting for the next excitation.

[0047] The driving gear 1210 drives the reversing gear 1212 and the frequency increasing gear 1220 to rotate. The reversing gear 1212 drives the frequency increasing gear 1214 to rotate. The frequency increasing gear 1214 drives the transmission shaft 1215 to rotate, and the transmission shaft 1215 drives the transmission gear 1216 installed with the one-way bearing 1217 to rotate. The frequency increasing gear 1220 drives the transmission shaft 1221 to rotate, and the transmission shaft 1221 drives the transmission gear 1223 installed with the one-way bearing 1222 to rotate. The transmission gear 1216 and the transmission gear 1223 jointly drive the magnet disc gear 1219 to rotate. The frequency increasing gear 1214 and the frequency increasing gear 1220 have fewer teeth, thus having a frequency increasing effect on the rotating speed of the driving gear 1210, significantly improving the energy conversion efficiency and output power. It is worth noting that the driving directions of the one-way bearing 1217 and the one-way bearing 1222 are opposite, so no matter which direction the magnet disc gear rotates, the magnet disc gear 1219 always rotates in the same direction. The magnet disc gear 1219 drives the driving support shaft 1218 to rotate, and the driving support shaft 1218 drives the rotating magnet disc 1230 to rotate. The magnetic flux passing through the coil 1240 changes, thus generating electricity by electromagnetic induction. Due to the plurality of circular permanent magnets 1231 arranged in a circumferential array, one rotation of the rotating magnet disc 1230 can generate multiple magnetic excitations, having a frequency increasing effect. The coil 1240 is connected to an external circuit, and the generated electrical energy can be directly used or stored for later use.

[0048] The above embodiments are only the preferred embodiments of the present application, and do not limit the present application in any form. Although the present application has been disclosed with the preferred embodiments as above, it is not intended to limit the present application. Therefore, any simple modification, equivalent change and modification made to the above embodiments without departing from the technical solutions of the present application, and according to the technical essence of the present application, should fall within the scope of protection of the technical solutions of the present application.
