At this time, the cleaning sheet 212 cleans the dust and snow on the protective film 208 to ensure its light transmittance and cleanliness.

[0043] Example 3

[0044] The solar-powered educational vehicle of this embodiment has the same basic structure as that of the second embodiment, except that: Figure 1 , 24, it also includes a power output mechanism 3, the output mechanism 3 includes a driving motor 303 and a shell 301 and a bottom plate 316 fixedly connected to each other, a frame-shaped groove 300 is set on the top of the shell 301, and the solar cell panel 202 is placed in the frame-shaped groove 300 to prevent the solar cell panel 202 from shifting; a stabilizing frame 314 is fixed on the bottom plate 316, and a circuit control board 315 is clamped on the top of the stabilizing frame 314. The driving motor 303 is fixed on the bottom plate 316 through the support frame 302, and its output end is fixedly connected to the first gear 304; a first rotating rod 306 is rotatably connected between the two side plates of the housing 301, and the two ends of the first rotating rod 306 are respectively fixedly connected to the second gear 305 and the third gear 307, the first gear 304 is meshed with the second gear 305, the third gear 307 is meshed with the fourth gear 308, and the fourth gear 308 is fixed on the second rotating rod 309, one end of the second rotating rod 309 passes through a side plate of the housing 301 and is fixedly connected to the fifth gear 310, the fifth gear 310 is meshed with the sixth gear 311, and the sixth gear 311 is fixed on the third rotating rod 312, and one end of the third rotating rod 312 passes through the other side plate of the housing 301 and is detachably fixedly connected to the steering cam 313; the steering cam 313 is transmission-connected to the steering wheel 410 through the steering mechanism 4;

[0045] like Figure 5 , 6 As shown, the steering mechanism 4 includes a turntable 401 and a fourth rotating rod 408. The circumference of the turntable 401 is rotatably connected to the top rod 403 through the rotating frame 400, and the rod body of the top rod 403 is pressed tightly against the circumference of the wheel of the steering cam 313; the two ends of the fourth rotating rod 408 are respectively fixedly connected to the turntable 401 and the front fork 409, and the steering wheel 410 is rotatably connected to the front fork 409. The matching arrangement of the top rod 403 and the steering cam 313 achieves the purpose of adjusting the rotation trajectory of the steering wheel 410, so that the rotation trajectory can be rotated accordingly with the direction of light, thereby improving the energy storage efficiency of the solar cell panel 202.

[0046] In the solar-powered educational vehicle of this embodiment, the first gear 304, the third gear 307 and the fifth gear 310 are small gears, the second gear 305, the fourth gear 308 and the sixth gear 311 are large gears, and three pairs of large and small gears are arranged in coordination, and three-stage transmission makes the transmission more stable and more efficient, while reducing the power required by the drive motor 303 and making it easier to start. It should be noted that the circuit control board 315 is electrically connected to the drive motor 303 and the solar panel 202, and as an expansion, it may also include a storage battery for converting solar energy into electrical energy, etc. Since the conversion of solar energy into electrical energy and then outputting it through the motor is a mature existing technology, it will not be described in detail in this embodiment.

[0047] When the solar-powered educational vehicle of the present embodiment is in operation, first, the circuit control board 315 will control the driving motor 303 to rotate, and then the first gear 304 will rotate, and the second gear 305 will rotate under the rotation of the first gear 304, because the diameter of the first gear 304 is smaller than the diameter of the second gear 305, and therefore the rotation speed of the second gear 305 is not as fast as the rotation speed of the first gear 304, and at this time, the walking wheel 1 will also start to rotate under the drive of the first rotating rod 306, and the third gear 307 on the first rotating rod 306 will also rotate, and the fourth gear 308 will rotate under the rotation of the third gear 307, and because the diameter of the third gear 307 is smaller than the diameter of the fourth gear 308, the rotation speed of the fourth gear 308 is not as fast as the rotation speed of the third gear 307, and at the same time, the second rotating rod 309 on one side of the fourth gear 308 will also rotate, and the fifth gear 310 on the second rotating rod 309 will also rotate, and the sixth gear 311 will rotate under the drive of the first rotating rod 306. The fifth gear 310 rotates under the rotation of the fifth gear 310. Because the diameter of the fifth gear 310 is smaller than the diameter of the sixth gear 311, the rotation speed of the sixth gear 311 is not as fast as the rotation speed of the fifth gear 310. At the same time, the third rotating rod 312 fixed on one side of the sixth gear 311 will also rotate. Because of the rotation of the third rotating rod 312, the steering cam 313 located at one end of the third rotating rod 312 will also rotate slowly. Because the steering cam 313 is designed with protrusions of different sizes, the protrusion will contact the steering mechanism 4 and control the steering mechanism 4 to perform steering movement. The shape of the steering cam 313 is designed according to a predetermined route. A series of gear reduction mechanisms are arranged between the steering cam 313 and the motor 206, which can control the motor 206 to rotate to a certain number of circles. The shape of the steering cam 313 changes the forward direction of the trolley by changing the shape of the steering cam 313. Combined with the diameter of the walking wheel 1 and the reduction ratio between it and the motor 206, the trolley can be controlled to turn at a fixed distance.

[0048] Example 4

[0049] The solar powered educational vehicle of this embodiment has the same basic structure as that of the third embodiment, except that: Figure 5 , 6As shown, the bottom of the rotating disk 401 is fixedly connected to the rotating tube 404, and the bottom of the rotating tube 404 is rotatably connected to the sleeve 407. The rotating tube 404 is surrounded by a torsion spring 406, one end of the torsion spring 406 is fixed to the outer wall of the rotating tube 404, and the other end is fixed to the sleeve 407. The bottom of the sleeve 407 is fixedly connected to the bottom plate 316; the fourth rotating rod 408 passes through the bottom plate 316, the sleeve 407, the rotating tube 404 and the rotating disk 401 in sequence, and the steering wheel 410 is reset by the torsion spring 406. A support rod 402 tangent to the rotating disk 401 is fixed on the side of the rotating frame 400, and an adjustment rod 411 passes through the support rod 402 and the top rod 403, and the degree of close contact between the top rod 403 and the circumference of the steering cam 313 can be adjusted by the adjustment rod 411. The adjustment rod 411 can be a combination of an adjustment bolt and a nut.

[0050] Example 5

[0051] The basic structure of the solar-powered educational vehicle in this embodiment is the same as that in the fourth embodiment, except that: Figure 7 As shown, the shape of the steering cam 313 is a shape that matches the specific motion trajectory of the trolley to adapt to different offset trajectories of illumination. Figure 5 As shown, a protrusion 405 is fixed to one side of the rotating tube 404 and the top of the sleeve 407 respectively, and a torsion spring 406 is between the two protrusions 405 .

[0052] When the solar-powered educational vehicle of the present embodiment is running, when the protrusion on the protrusion 405 hits the top rod 403, because one end of the top rod 403 is rotatably connected to one side of the turntable 401, the top rod 403 will hit the support rod 402, and the support rod 402 will drive the turntable 401 to rotate. At this time, the fourth rotating rod 408 will also rotate. At this time, the rotating frame 409 will rotate under the rotation of the fourth rotating rod 408, and the steering wheel 410 will also start to rotate. When the protrusion on the protrusion 405 slowly leaves the top rod 403, the turntable 401 will reset the steering wheel 410 under the action of the torsion spring 406. The torsion spring 406 can also play a buffering role on the steering wheel 410, so that it can adapt to terrain changes more stably.

[0053] There are other specific embodiments of the present invention, which can change the running track of the trolley by changing the shape of the steering cam 313. Figure 8 , 9As shown, the shape of the steering cam is simulated and optimized by using Matlab software to reversely deduce the shape of the steering cam. After multiple simulations and optimizations of the trajectory curve, the optimal trajectory curve and turning angle curve of the solar electric vehicle are obtained. The user can control the running trajectory of the car by replacing the steering cam. The circular steering cam will make the car move in a straight line, and after replacing the steering cam 313 of different shapes, the car will move in different trajectories. At the same time, in the process of disassembling and assembling the car with the replaced steering cam 313, the user can understand the running structure of the car, and then understand the mechanical knowledge involved, so as to achieve the purpose of educational puzzle; the shape of the steering cam 313 includes but is not limited to a circle, an ellipse, and other irregular line segments.
