Preferred embodiments of the present invention will be described below with reference to the accompanying drawings. In each drawing referred to in the following description, components equivalent to those in the other drawings are denoted by the same reference numerals.
(Embodiment)
(Configuration of solar car 10)
First, with reference to FIG. 1, the structure of the solar car 10 which concerns on embodiment of this invention is demonstrated. A solar car 10 shown in FIG. 1 is divided into a solar car body 11 and a remote controller 21. The solar car main body 11 and the remote control unit 21 are connected by four cables 31 with wormworm clips. This solar car 10 is an assembly type that can be easily assembled by children who use teaching materials while having fun.

First, the solar car main body 11 includes a body arm 12, a front wheel 13, a left rear wheel 14, a right rear wheel 15, a left motor 16, a right motor 17, and a gear box 18.
A front wheel 13 and a gear box 18 are attached to the body arm 12. The gear box 18 has gears for independently transmitting the rotational force of the left electric motor 16 to the left rear wheel 14 and the rotational force of the right electric motor 17 to the right rear wheel 15. A left motor 16 and a right motor 17 are attached to the gear box 18. The front wheel 13 is not connected to the left electric motor 16 and the right electric motor 17, and a fixed vehicle type caster, for example, is used for the front wheel 13. The left rear wheel 14 is connected to the left electric motor 16 via a gear box 18. The right rear wheel 15 is connected to the right electric motor 17 via a gear box 18. The left motor 16 drives the left rear wheel 14, and the right motor 17 drives the right rear wheel 15. The left motor 16 and the right motor 17 are DC motors having the same performance.

The remote control unit 21 includes a photovoltaic cell 22 and a light shielding unit 23.
The photovoltaic cell 22 generates electricity by receiving light. The photovoltaic cell 22 is composed of a plurality of single modules. Among the plurality of single modules, the single modules constituting the left module 22a arranged in the left region are connected in series in the arrangement direction. Similarly, the single modules constituting the right module 22b arranged in the right region are connected in series in the arrangement direction. The left module 22a is connected to a positive terminal 22c and a negative terminal 22d, and the right module 22b is connected to a positive terminal 22e and a negative terminal 22f.

  The light shielding unit 23 includes a left light shielding unit 23L corresponding to the left module 22a and a right light shielding unit 23R corresponding to the right module 22b. The left light-shielding portion 23L can be moved in the direction of the arrow YA shown in the figure, and can cover the left module 22a. Further, the right light-shielding portion 23R can be moved in the direction of the arrow YB shown in the figure, and can cover the right module 22b. With the left light shielding part 23L and the right light shielding part 23R, the left module 22a and the right module 22b of the photovoltaic cell 22 can be covered one by one or both sides simultaneously. As the material of the light shielding portion 23, cardboard, synthetic resin, or the like that can block light is used. In addition to the folding type, for example, a sliding type can be used for the light shielding unit 23. Furthermore, even if there is no light-shielding part 23, the light which enters into the left module 22a or the right module 22b can be blocked by hand.

The cable 31 with a caterpillar clip is a conductor cable with a caterpillar clip attached to both ends. Since the caterpillar clip is attached, the electrical connection between the terminals can be freely connected and changed. Further, a crocodile clip may be used instead of the caterpillar clip. In addition, since the solar car main body 11 travels away from the remote control unit 21, a cable 31 with a wormworm clip having a longer length is used.
For example, as shown in FIG. 2, the positive terminal 22 c and the negative terminal 22 d of the left module 22 a of the photovoltaic cell 22 are connected to the positive terminal and the negative terminal of the left motor 16 by using four cables 31 with a caterpillar clip. . Further, the positive terminal 22 e and the negative terminal 22 f on the left side 22 b of the photovoltaic cell 22 are connected to the positive terminal and the negative terminal of the right motor 17.

(Operation example of the solar car main body 11 using the remote controller 21)
Then, with reference to FIGS. 3-6, the operation example of the solar car main-body part 11 using the remote control part 21 is demonstrated. In the description of the present embodiment, a light bulb 32 is used as a light source of light applied to the photovoltaic cell 22.
First, as shown in FIG. 3A, both the left module 22a and the right module 22b of the photovoltaic cell 22 are not covered with the left light shielding part 23L and the right light shielding part 23R. At this time, when the photovoltaic cell 22 receives light from the light bulb 32, electricity is generated almost uniformly by the left module 22a and the right module 22b. For this reason, as shown in FIG.3 (b), the left motor 16 and the right motor 17 rotate at the substantially same rotation speed, and the solar car main-body part 11 advances substantially straight.

  Next, as shown in FIG. 4A, only the right module 22b of the photovoltaic cell 22 is covered with the right light shielding portion 23R. At this time, when the photovoltaic cell 22 receives light from the light bulb 32, electricity is generated mainly by the left module 22a. For this reason, as shown in FIG.4 (b), the rotation speed of the left motor 16 connected with the left side module 22a becomes larger than the rotation speed of the right motor 17. FIG. Therefore, the solar car main body 11 advances in the direction of the arrow YR shown in the drawing, that is, the direction to the right.

Further, as shown in FIG. 5A, only the left module 22c of the photovoltaic cell 22 is covered with the left light shielding portion 23L. At this time, when the photovoltaic cell 22 receives light, electricity is generated mainly only by the right module 22b. For this reason, as shown in FIG.5 (b), the rotation speed of the right motor 17 connected with the right module 22b becomes larger than the rotation speed of the left motor 16. FIG. Therefore, the solar car main body 11 proceeds in the direction of the arrow YL shown in the drawing, that is, the left side direction.
Thus, the direction in which the solar car main body 11 travels can be freely changed by changing the method of covering the photovoltaic cell 22 by the light shielding portion 23. That is, the photovoltaic cell 22 can be used as a remote controller that also has a power generation function. And children who use teaching materials can learn about photovoltaic cells while actually moving and enjoying the model freely.

  In addition to the above, the connection method between the terminals can be changed. For example, as shown in FIG. 6A, the left module 22a and the right module are connected by connecting the negative terminal 22d of the left module 22a of the photovoltaic cell 22 and the positive terminal 22e of the right module 22b with a cable 31 with a caterpillar clip. 22b is connected in series. The positive terminal 22 c of the left module 22 a is connected to the positive terminals of the left motor 16 and the right motor 17. Further, the negative terminal 22 f of the right module 22 b is connected to the negative terminals of the left motor 16 and the right motor 17.

With such a connection method, even if either the left module 22a or the right module 22b of the photovoltaic cell 22 is covered with the light shielding part 23, the traveling direction of the solar car main body 11 cannot be changed. However, the running speed of the solar car main body 11 can be changed by changing the way of covering the module of the photovoltaic cell 22 by the light shielding portion 23.
As shown in FIG. 6B, when only the right module 22 b is covered with the right light-shielding portion 23 </ b> R, the amount of power that can be generated when the photovoltaic cell 22 receives light from the light bulb 32 is generated by the photovoltaic cell 22. It is almost half of the maximum power generation that can be produced. For this reason, the solar car main-body part 11 advances straight more slowly than the case of FIG.6 (c) mentioned later.

Then, as shown in FIG. 6C, if the left and right modules 22a and 22b are not covered with the light shielding portion 23, the photovoltaic cell 22 generates the maximum amount of electricity. For this reason, the solar car main body 11 moves straight at a higher speed than in the case of FIG.
By changing the connection method as described above, the running speed of the solar car main body 11 can be changed by changing the method of covering the module of the photovoltaic cell 22 by the light shielding portion 23.

  The ordinary photovoltaic cell as described above in the background art has only one set of the positive electrode terminal and the negative electrode terminal. On the other hand, the photovoltaic cell 22 used in this example is divided into a left module 22a and a right module 22b, and two sets of positive and negative terminals are attached. For this reason, modules can be connected in series or in parallel in one photovoltaic cell. And the direction and speed which the solar car main-body part 11 advances can be changed using the photovoltaic cell 22 as a remote control.

(Modification)
In addition, although the photovoltaic cell 22 is divided into two, the left module 22a and the right module 22b, you may divide into more modules. For example, four modules can be provided, and two of the four modules can be used for the left module and the right module. As described above, various ways of connection can be made using the cable 31 with the caterpillar clip, so that the children who use the teaching materials understand that the power generation amount increases as the number of modules connected in series increases, for example. it can.
Further, in this embodiment, the wheels connected to the electric motor are only a pair of left and right rear wheels, but in addition to this, for example, four wheels are attached to the front, rear, left and right, and these wheels are connected to each module. If the control is performed by a plurality of systems, a more complicated movement such as rotating the solar car main body 11 can be performed.

  Furthermore, you may add a storage battery and connect a storage battery with a photovoltaic cell. For example, as shown in FIG. 7, a terminal 41 for electrically connecting a capacitor 40 charged with electric charge to the left motor 16 and the right motor 17 is provided on the trunk arm 12 of the solar car main body 11. . And after attaching the capacitor | condenser 40 to the terminal 41, the capacitor | condenser 40, the left motor 16, and the right motor 17 can be connected with the cable 31 with a caterpillar clip. Thereby, the solar car can be upgraded to a hybrid solar car driven by both the photovoltaic cell 22 and the capacitor 40. As the capacitor 40, for example, an electrolytic capacitor having a rating of about 2.5V and 10F may be used. Thereby, it is possible to make the children who use the teaching materials more enjoyable to understand that the maximum power generation amount is obtained when both the photovoltaic cell 22 and the capacitor 40 are functioning.

  For example, it can be used as a learning material in science classes at elementary and junior high schools that deal with the mechanism of photovoltaic cells.
