[0030] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0031] In the description of the present invention, it is necessary to understand that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship are based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0032] Example: Refer to Figure 1-Figure 9A lightweight foldable satellite antenna includes an antenna base 1 and a receiver 20, and further includes: a storage tube 2, which is rotatably arranged on the antenna base 1; a piston plate 9 slidably arranged in the antenna base 1, a mounting rod 19 is fixedly connected to the piston plate 9, and the receiver 20 is fixedly connected to the mounting rod 19; a first mounting frame and a second mounting frame, both of which are fixedly mounted on the piston plate 9, and the second mounting frame is arranged in the middle of the first mounting frame; a first reflecting plate 22, which is rotatably arranged on the first mounting frame; a second reflecting plate 23, which is rotatably arranged on the second mounting frame; The first reflective plate 22 and the second reflective plate 23 are each provided with multiple groups, and the first reflective plate 22 and the second reflective plate 23 are arranged crosswise; the first folding drive unit is fixedly mounted on the storage tube 2; the second folding drive unit is fixedly mounted on the storage tube 2, and the output end of the second folding drive unit is arranged on the inner side of the first drive unit; when the piston plate 9 descends, the first folding drive unit and the second folding drive unit respectively drive the first reflective plate 22 and the second reflective plate 23 to rotate and be stored in the storage tube 2, and after the first reflective plate 22 is folded, the folded second reflective plate 23 is covered on the inner side.

[0033] When in use, the piston plate 9 is driven to slide downward (slide toward the closed end of the storage tube 2). During this process, under the action of the first folding drive unit and the second folding drive unit, the piston plate 9 drags the first reflective plate 22 and the second reflective plate 23 through the first mounting frame and the second mounting frame respectively, and the end of the first reflective plate 22 and the second reflective plate 23 close to the axis of the storage tube 2 rotates toward the inside of the storage tube 2, and then the first reflective plate 22 and the second reflective plate 23 follow the piston plate 9 to move toward the storage tube 2, and finally the first reflective plate 22 and the second reflective plate 23 are stored into the storage tube 2.

[0034] Among them, the first reflective plate 22 and the second reflective plate 23 are both fan-shaped, and multiple groups of first reflective plates 22 and multiple groups of second reflective plates 23 are combined into a round cover-shaped reflective plate. When the piston plate 9 moves downward, the end with a smaller width of the first reflective plate 22 and the second reflective plate 23 first rotates into the storage tube 2.

[0035] Reference Figure 6 and Fig. 9 The first mounting frame includes a first mounting column 14 fixedly connected to the piston plate 9, a first mounting ring 15 is fixedly connected to the first mounting column 14, a groove 16 is provided on the first mounting ring 15, a first connecting ring 24 is fixedly connected to the first reflecting plate 22, and the first connecting ring 24 is rotatably connected to the first mounting ring 15, the second mounting frame includes a second mounting column 17 fixedly connected to the piston plate 9, a second mounting ring 18 is fixedly connected to the second mounting column 17, a second connecting ring 25 is fixedly connected to the bottom of the second reflecting plate 23, and the second connecting ring 25 is rotatably connected to the second mounting ring 18, wherein the diameter of the second mounting ring 18 is smaller than the diameter of the first mounting ring 15, and the first mounting ring 15 is coaxial with the second mounting ring 18.

[0036] When the piston plate 9 descends, the piston plate 9 simultaneously drags the first mounting ring 15 and the second mounting ring 18 to move toward the inside of the storage tube 2 through the first mounting column 14 and the second mounting column 17. During this process, the first folding driving part and the second folding driving part drive

[0037] When the first reflector 22 is turned over and enters the storage tube 2, it rotates around the axis of the first connecting ring 24;

[0038] When the second reflection plate 23 is turned over and enters the storage tube 2, it rotates around the axis of the second connection ring 25.

[0039] like Fig. 9 As shown, compared with the rotation axis of the first connecting ring 24, the rotation axis of the second connecting ring 25 is closer to the axis of the storage tube 2. Therefore, when the first reflector 22 and the second reflector 23 rotate, the rotated second reflector 23 is covered on the inner side by the first reflector 22, thereby avoiding collision between adjacent reflectors (avoiding collision between the edges of adjacent reflectors and preventing adjacent reflectors from being stuck when rotating).

[0040] Reference Figure 7 and Fig. 9 The first folding driving part includes a first mounting seat 26 fixedly connected to the inner wall of the storage tube 2, and a first pushing wheel 27 is rotatably connected to the first mounting seat 26, and the first pushing wheel 27 is attracted to the back side of the first reflecting plate 22. The second folding driving part includes a second mounting seat 28 fixedly connected to the storage tube 2, and a second pushing wheel 29 is rotatably connected to the second mounting seat 28, and the back side of the second reflecting plate 23 is attracted to the second pushing wheel 29; the first pushing wheel 27 and the second pushing wheel 29 are both magnets, and the back sides of the first reflecting plate 22 and the second reflecting plate 23 are both provided with a metal coating that is attracted to the magnet, wherein the metal coating is preferably a metal coating containing iron, such as epoxy micaceous iron primer.

[0041] When storing the reflective plates, the first reflective plate 22 abuts against the first pushing wheel 27, and as the piston plate 9 slides, the first pushing wheel 27 cooperates with the first mounting ring 15 to drive the first reflective plate 22 to flip; the second reflective plate 23 abuts against the second pushing wheel 29, and as the piston plate 9 slides, the second pushing wheel 29 cooperates with the second mounting ring 18 to drive the second reflective plate 23 to flip, and then as the piston plate 9 moves, the first reflective plate 22 and the second reflective plate 23 are dragged into the storage tube 2.

[0042] When the piston plate 9 rises (moves toward the opening of the storage tube 2), the first reflector 22 and the second reflector 23 rise, and are driven to spread out in all directions by the adsorption of the first push wheel 27 and the second push wheel 29 respectively.

[0043] Reference Figure 1 , Figure 7 and Fig. 9 A limiting plate 21 is fixedly connected to the mounting rod 19 . When the first reflecting plate 22 and the second reflecting plate 23 are unfolded, the first reflecting plate 22 and the second reflecting plate 23 are both against the limiting plate 21 .

[0044] When the piston plate 9 rises and drives the first reflective plate 22 and the second reflective plate 23 to rise, the first reflective plate 22 and the second reflective plate 23 are driven to expand to the surroundings under the adsorption action of the first push wheel 27 and the second push wheel 29 respectively. At the same time, the piston plate 9 drives the limiting plate 21 to rise. When the first reflective plate 22 and the second reflective plate 23 are fully expanded, the limiting plate 21 abuts against the first reflective plate 22 and the second reflective plate 23 to limit the first reflective plate 22 and the second reflective plate 23 to prevent the first reflective plate 22 and the second reflective plate 23 from rotating when in use.

[0045] Reference Figure 4 A second motor 11 is fixedly connected to the upper portion of the storage cylinder 2 , a screw rod 10 is fixedly connected to the output end of the second motor 11 , and the screw rod 10 is threadedly connected to the piston plate 9 .

[0046] When in use, start the second motor 11, the second motor 11 drives the screw 10 to rotate, and the screw 10 drives the piston plate 9 to move inside the storage tube 2, controlling the first reflective plate 22 and the second reflective plate 23 to be stored into the storage tube 2 or controlling the first reflective plate 22 and the second reflective plate 23 to move to the outside of the storage tube 2 and unfold.

[0047] Reference Figure 4 A first one-way valve 12 is fixedly connected to the piston plate 9, and a second one-way valve 13 is fixedly connected to the storage tube 2; when the first reflecting plate 22 and the second reflecting plate 23 move toward the inside of the storage tube 2, the piston plate 9 drives the gas in the storage tube 2 to be discharged to the first reflecting plate 22 and the second reflecting plate 23 through the first one-way valve 12; when the first reflecting plate 22 and the second reflecting plate 23 are unfolded, the piston plate 9 drives the air to enter the storage tube 2 through the second one-way valve 13.

[0048] When the piston plate 9 drives the first reflecting plate 22 and the second reflecting plate 23 to unfold, the piston plate 9 absorbs external air through the second one-way valve 13 and stores the air in the inner cavity formed by the storage tube 2 and the piston plate 9 .

[0049] When the piston plate 9 moves toward one end of the second motor 11, the piston plate 9 compresses the air in the inner cavity of the storage tube 2 and blows it toward the first reflecting plate 22 and the second reflecting plate 23 entering the interior of the storage tube 2 through the first one-way valve 12, thereby cleaning the surfaces of the first reflecting plate 22 and the second reflecting plate 23.

A mounting box 4 is fixedly connected to the antenna base 1. The mounting shaft 3 extends to the mounting box 4 and is fixedly connected to a worm gear 5. A worm 6 is rotatably connected to the mounting box 4, and the worm 6 is meshed with the worm wheel 5. One end of the worm 6 is fixedly connected to an adjustment handle 8. A first motor 7 is fixedly connected to the outer wall of the mounting box 4, and an output end of the first motor 7 is fixedly connected to the other end of the worm 6.
