[0044] Example 1

[0045] like Figures 1 to 14As shown, the present invention provides a sunflower model for teaching aids and toys, which includes: a bottom plate 11, a base 9, a motor 8, a battery, a steering assembly and a sunflower modeling board 13, on which a solar light chaser main control board 2 is provided, and a photoresistor is provided on the solar light chaser main control board 2. The base 9 is connected to the bottom plate 11, the motor 8 is connected to the base 9, the solar light chaser main control board 2 is connected to the motor 8, the solar light chaser main control board 2 is connected to the battery, one end of the steering assembly is connected to the motor 8, and the other end is connected to the sunflower modeling board 13.

[0046] The technical solution of the present invention can detect the direction of the surrounding light sources by setting a photoresistor on the solar light chaser main control board 2, so as to rotate the motor 8 connected to the solar light chaser main control board 2, drive the sunflower modeling board 13 to rotate following the change of the direction of the multiple light sources, and achieve the light chasing effect. The base 9, the bottom plate 11 and the motor 8 and other components are connected by splicing and plugging, which is convenient for disassembly, and can clearly display the components and working principle of the sunflower light chasing model, which is conducive to teaching.

[0047] like Fig.10 and Fig.11 As shown, the two photoresistors R3 and R4 are respectively arranged on the left and right sides of the solar tracker main control board 2. The solar tracker main control board 2 is also provided with a motor interface 10 and a power interface 12. The motor interface 10 is used to connect to the motor 8, and the power interface 12 is used to connect to the battery in the battery box 6. The 4.5V power supply is input through the P1 interface, and the photoresistors R3 and R4 form a voltage divider circuit. The output voltage changes with the change of the light intensity difference irradiated to the two photoresistors, hereinafter referred to as the variable input voltage, and the resistors R1 and R2 form a fixed voltage divider circuit. The output voltage is fixed to VCC / 2, hereinafter referred to as the fixed input voltage. The fixed input voltage is connected to the same direction input terminal INPUT1 and the reverse input terminal NF2 of the power amplifier chip TDA2822, and the variable input voltage is connected to the reverse input terminal NF1 and the same direction input terminal INPUT2 of the power amplifier chip. When there is a difference in the light intensity irradiating the two photoresistors, if the light intensity irradiating R3 is stronger and the light intensity irradiating R4 is weaker, the resistance of R3 decreases, the resistance of R4 increases, and the variable input voltage increases, then the voltage at the output terminal OUTPUT1 of the power amplifier chip decreases, and the voltage at the output terminal OUTPUT2 increases, and the current flows from OUTPUT2 to OUTPUT1 through motor 8. It is stipulated that at this time, the direction of motor 8 is forward, and motor 8 rotates toward the light source until the light intensity irradiating the photoresistors R3 and R4 is balanced again; conversely, when the light intensity irradiating R3 is weaker and the light intensity irradiating R4 is stronger, the current flows from OUTPUT1 to OUTPUT2 through motor 8, and motor 8 reverses and also rotates toward the light source until it reaches balance again.

[0048] like Figures 3 to 5As shown, a convex dot array is provided on the bottom plate 11, and the base 9 is plugged into the bottom plate 11 through the convex dot array. A groove hole is also provided on the bottom plate 11, and a screw hole is also provided on the base 9. The screw passes through the screw hole and the groove hole to fix the base 9 on the bottom plate 11. Specifically, the convex dot array provided on the bottom plate 11 can be compatible with large-particle building blocks for plug-in construction. At the same time, a groove hole is also provided at the center of the convex dot and the base 9 itself, and screws or rivets and other parts can be used for secondary reinforcement.

[0049] The steering assembly includes a first steering seat 1, a porous connector 3 and a second steering seat 4. One end of the porous connector 3 is connected to the first steering seat 1, and the other end is connected to the second steering seat 4. The other end of the first steering seat 1 is connected to the second angle code 7 and the motor 8, and the other end of the second steering seat 4 is connected to the sunflower shaped plate 13.

[0050] The battery is installed in the battery box 6, one side of the battery box 6 is connected to the steering assembly, and the bottom end of the battery box 6 is connected to the second angle code 7 through the first angle code 5. Specifically, in this embodiment, the first angle code 5 is a double-row angle code.

[0051] like Figure 6 As shown, the base 9 is provided with a convex dot array and groove holes, and the motor 8 shaft of the motor 8 is inserted into the convex dot array.

[0052] like Figure 7 As shown, the second angle code 7 is provided with a hole matrix, which can be easily assembled with the motor 8 and steering gear components, and can also be combined with other plastic parts. Figure 8 As shown, the motor 8 is connected to the second angle bracket 7 by bolts, and the bolts pass through holes set on the second angle bracket 7.

[0053] like Fig.12 As shown, the porous connector 3 is a four-hole connector, and the material of the porous connector 3 is plastic.

[0054] The bottom plate 11 and the base 9 are both open mold injection molded parts. Specifically, in this embodiment, the bottom plate 11 is a square bottom plate 11, and the base 9 is a round base 9. In addition, the second angle code 7, the first steering seat 1, the second steering seat 4 and the porous connector 3 are all open mold injection molded parts, and the material is ABS material.

[0055] Motor 8 is a brushless DC reduction motor. In this embodiment, the power supply voltage is only 4.5V, which meets the safety voltage specified in the national standard. The ambient light changes are collected by the two photoresistors on the left and right, and high and low changing signals are generated and transmitted to the power amplifier chip, so that the output of the power amplifier chip produces corresponding voltage changes, and the magnitude and direction of the current flowing through the motor 8 are adjusted, thereby realizing an interactive light chasing demonstration function. In addition, all the structural plastic parts of this scheme are open mold injection molded parts, and each plastic part has good compatibility and expansibility. It can be assembled and combined with many electronic components, power components and structural parts, which is very convenient for the development and use of STEM teaching.

[0056] Example 2

[0057] like Fig.13 As shown, two porous connectors 3 are connected between the first steering seat 1 and the second steering seat 4, which can extend the entire steering assembly, make the steering assembly have a wider range of up and down angle adjustment, and make the solar tracker main control board 2 connected to the first steering seat 1 better collect solar energy. The rest of the parts are basically the same as Example 1.

[0058] Example 3

[0059] like Fig.14 As shown, on the basis of Example 2, two steering seats are connected between the two porous connecting members 3, which also makes the entire steering assembly extended. The rest of the parts are basically the same as Example 1.
