Embodiment 1
[0042] This embodiment provides an intelligent focusing spaceborne camera lens, such as figure 1 As shown, the intelligent focusing spaceborne camera lens includes a lens barrel 1, a lens 2, a hood 3 and a guide rail 4, combined with image 3 As shown, the intelligent focusing spaceborne camera lens also includes a spring 5, wherein the lens barrel 1, the hood 3 and the spring 5 are made of a shape memory material.
[0043] Specifically, combine Figure 1-Figure 4 As shown, the state of the lens barrel 1 includes a compressed state and an expanded state, and the state of the intelligent focusing spaceborne camera lens is determined by the state of the lens barrel 1 . The spring 5 includes a plurality of spring bars distributed on the inner wall of the lens barrel 1. The two ends of the spring bars are respectively fixed to the two ends of the lens barrel 1. The fixing methods include gluing and resin curing. When the lens barrel 1 is in such a state as figure 1 In the compre...
Embodiment 2
[0048] On the basis of the above-mentioned embodiments, this embodiment combines Figure 1-Figure 3 As shown, the external stimuli that the intelligent focusing spaceborne camera lens is subjected to include but are not limited to thermal drive, electric drive, microwave drive, and radio frequency drive. When adopting the heat-driven mode, on the outer surface or the inner surface of the lens barrel 1, or on the inner and outer surfaces, a resistive film heater is pasted, and the film heater pasted on the surface of the lens barrel 1 is energized. When the temperature of the lens barrel 1 rises to After the glass transition temperature is above, the lens barrel 1 starts to recover from the compressed state to the original state, and stops heating when the lens barrel 1 is fully expanded. When the electric driving mode is adopted, one or more of the conductive enhancement phases such as single-walled, multi-walled carbon nanotubes, graphene, carbon black, carbon nanopaper, carb...
Embodiment 3
[0051] On the basis of the above-mentioned embodiments, this embodiment combines Figure 1-Figure 5 As shown, the lens barrel 1 includes a guide block 15, the shape of the guide block 15 matches the shape of the guide rail 4, the lens barrel 1 is compressed and expanded on the guide rail 4, and the left end of the lens barrel 1 is fixed.
[0052] Specifically, the excitation of the lens barrel 1 makes the lens of the intelligent focusing spaceborne camera change from figure 1 The compressed state shown transitions to figure 2 In the unfolded state shown, the first lens barrel 11, the second lens barrel 12, the third lens barrel 13 and the fourth lens barrel 14 are all fixedly connected to the guide block 15, and the guide block 15 slides to the right on the guide rail 4 to realize from figure 1 The compressed state shown transitions to figure 2 As shown in the unfolded state, the intelligent focusing spaceborne camera lens is in the unfolded state. At this time, the intell...
