Therefore, It is to be understood that equivalents and modifications are possible.

The present invention relates to a solar panel deployment hinge that can increase the reliability and stability of the satellite body by preventing impact loads when the solar panel is deployed using a spring of a shape memory alloy material, and a method of deploying the solar panel using the hinge. will be.

1 is a view showing a folded shape of the hinge according to the present invention, with reference to FIG. 1 will be described for the solar panel deployment hinge according to the present invention.

First, the solar panel deployment hinge 100 includes a first hinge fitting 110 coupled to a first solar panel, a second hinge fitting 120 coupled to a second solar panel, and one end of the first hinge fitting 110. And a spring 140 that is coupled to the other end of the steel tape 130 and the first hinge fitting 110 and the second hinge fitting 120 that are coupled to the second hinge fitting 120. Include.

The spring 140 is mounted between the first hinge fitting 110 and the second hinge fitting 120 and may be formed of a shape memory alloy. The shape memory alloy is formed by forming a material of a certain shape at a higher temperature than the critical temperature (shaping treatment temperature), and then quenching it to remember the shape. It is a material that returns to the original shape that was remembered because the deformation is lost. In other words, titanium-nickel alloys are typical alloys that have a property of returning to a shape before deformation even if they are transformed into other shapes.

2 is a view showing the stiffness change of the spring made of the shape memory alloy, when the shape memory alloy is produced in the spring type as the present invention can induce a stiffness change. This will be described again below.

Meanwhile, the solar panel deployment hinge 100 according to the present invention may further include a power supply unit 150 for supplying power to the shape memory alloy. When the solar panel 200 is deployed, the power supply unit 150 supplies power at a predetermined early time, and stops supplying power at a preset second time.

For example, the steel tape 130 may be equipped with a strain gauge, the rigidity of the spring 140 of the hinge by varying the power supplied from the power supply unit 150 according to the strain of the strain gauge Induces a change to control the speed at which the solar panel 200 is deployed.

That is, if the strain of the strain gauge of the steel tape 130 is more than the predetermined level corresponds to the initial stage of the development of the solar panel 200, the strain value decreases as the development proceeds, by which the solar panel 200 is deployed When power is supplied through the power supply unit 150 at the start of the shape memory alloy spring 140, the rigidity is large enough to control the deployment speed of the hinge 100.

In the same principle, when the second half of the deployment of the predetermined solar panel 200 through the strain of the strain gauge of the steel tape 130, the power supply unit 150 stops supplying power to the shape memory alloy spring 140 Relative rigidity of the () so that the deployment rigidity of the hinge 100 can act on the full deployment of the solar panel. 3 is a view showing a shape in which the hinge according to the present invention is deployed.

4 illustrates an embodiment of a hinge according to the present invention, and shows a shape in which the solar panel 200 is fully developed by the solar panel deployment hinge according to the present invention. As such, by controlling the speed at which the solar panel is deployed using the shape memory alloy material, the structural stability of the solar cell attached to the solar panel can be guaranteed, and a sudden moment load is increased in the portion mounted on the solar panel and the satellite body. Can be prevented.

On the other hand, Figure 5 is a flow chart of a method for developing a solar panel using a hinge according to the present invention, with reference to Figure 5 describes a method for developing a solar panel using a hinge according to the present invention.

First, when power is supplied to a spring mounted between the first hinge fitting and the second hinge fitting (S10), the spring returns to the shape memorized by the temperature change when the spring is made of the shape memory alloy material. Using this restoring force to return to the memorized shape, the stiffness change of the spring is induced.

Next, the strain of the steel tape coupled to the first hinge fitting at one end and the second hinge fitting at the other end is compared with a predetermined value (S20) to adjust the amount of power supply according to the comparison result (S30). . The adjustment method is as described above in the solar panel deployment hinge. As the power supply amount is adjusted as described above, the stiffness of the spring is changed (S40), and the development speed of the steel tape is adjusted according to the stiffness of the spring (S50).

As described above, although the present invention has been described by way of limited embodiments and drawings, the present invention is not limited thereto and is intended by those skilled in the art to which the present invention pertains. Of course, various modifications and variations are possible within the scope of equivalents of the claims to be described.
