Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present application.

[0036] like Figure 1-4 As shown, a foldable and retractable device for an air-conditioning connector is provided on an umbilical tower 1000; the foldable and retractable device for an air-conditioning connector comprises: a base 100, a foldable frame 200 and a telescopic frame 300.

[0037] In this embodiment, the air conditioning connector is fixed to the end of the air conditioning pipe 1100, and is used to connect the air conditioning pipe 1100 with the fairing. The folding frame 200 is hinged to the base 100 through the first hinge shaft 801. The telescopic frame 300 is hinged to the folding frame 200 through the second hinge shaft 802; the first hinge shaft 801 and the second hinge shaft 802 are arranged in parallel.

[0038] Specifically, the first hinge shaft 801 and the second hinge shaft 802 are both fixedly connected to the folding frame 200 , the base 100 is rotatably connected to the first hinge shaft 801 via a bearing, and the telescopic frame 300 is rotatably connected to the second hinge shaft 802 via a bearing.

[0039] In addition, in some other embodiments of the present invention, the first hinge shaft 801 may also be fixedly connected to the base 100, and the folding frame 200 is rotatably connected to the first hinge shaft 801 via a bearing. At the same time, the second hinge shaft 802 is fixedly connected to the telescopic frame 300, and the folding frame 200 is rotatably connected to the second hinge shaft 802 via a bearing.

[0040] Similarly, the manner in which the folding frame 200 is hinged to the base 100 and the telescopic frame 300 is hinged to the folding frame 200 is also applicable to the solution of the present invention.

[0041] The foldable and retractable device of the air conditioner connector also includes a first folding drive mechanism 500 for driving the folding frame 200 to be in a folded state or an unfolded state, a second folding drive mechanism 600 for driving the telescopic frame 300 to be in a folded state or an unfolded state, and a telescopic drive mechanism 700 for driving the telescopic frame 300 to be in an extended state or a shortened state.

[0042] One end of the first folding driving mechanism 500 is hinged to the base 100 via the third hinge shaft 803, and the other end is hinged to the folding frame 200 via the fourth hinge shaft 804. One end of the second folding driving mechanism 600 is hinged to the folding frame 200 via the fifth hinge shaft 805, and the other end is hinged to the telescopic frame 300 via the sixth hinge shaft 806.

[0043] Preferably, the first folding driving mechanism 500 and the second folding driving mechanism 600 are both cylinders.

[0044] In addition, other telescopic mechanisms capable of achieving autonomous linear motion are also applicable to the present invention, such as a hydraulic cylinder, an electric push rod, etc.

[0045] The telescopic frame 300 includes a fixed frame body 301, a first telescopic frame body 302, and a second telescopic frame body 303. The fixed frame body 301 is hinged to the folding frame 200 via a second hinge shaft 802. The first telescopic frame body 302 is fixedly connected to the fixed frame body 301 at the side. That is, the rotation plane where the first telescopic frame body 302 is located is different from the rotation plane where the fixed frame body 301 is located, and when the telescopic frame 300 is in a folded state relative to the folding frame 200, the first telescopic frame body 302 is at least partially located at the side of the folding frame 200.

[0046] The first telescopic frame 302 and the second telescopic frame 303 are at least partially collinearly arranged, and the first telescopic frame 302 and the second telescopic frame 303 are slidably connected at the collinear portion, thereby achieving telescopic movement between the first telescopic frame 302 and the second telescopic frame 303 .

[0047] In addition, a limiting ring 304 is fixed on the second telescopic frame 303; the pulling wire rope 1200 connected to the air-conditioning connector is passed through the limiting ring 304, and the pulling wire rope 1200 is guided by the limiting ring 304, and the air-conditioning connector is unlocked and unplugged by pulling the pulling wire rope 1200.

[0048] The telescopic frame 300 further includes a first articulated seat 305 and a second articulated seat 306; the first articulated seat 305 is fixedly connected to the first telescopic frame body 302; the second articulated seat 306 is fixedly connected to the second telescopic frame body 303; the first articulated seat 305 is provided with a seventh articulated shaft, the second articulated seat 306 is provided with an eighth articulated shaft, and the seventh articulated shaft and the eighth articulated shaft are arranged parallel to each other. One end of the telescopic drive mechanism 700 is articulated to the first articulated seat 305 through the seventh articulated shaft, and the other end is articulated to the second articulated seat 306 through the eighth articulated shaft. The telescopic drive mechanism 700 can provide power for the telescopic movement between the first telescopic frame body 302 and the second telescopic frame body 303.

[0049] Preferably, the cross-sections of the first telescopic frame body 302 and the second telescopic frame body 303 are both rectangular; the first telescopic frame body 302 is at least partially sleeved on the outside of the second telescopic frame body 303. The first telescopic frame body 302 and the second telescopic frame body 303 with rectangular cross-section structures can enable the first telescopic frame body 302 to be sleeved on the outside of the second telescopic frame body 303, and the outer surfaces of the first telescopic frame body 302 and the second telescopic frame body 303 can provide sufficient installation positions, which is convenient for fixing and installing the first hinge seat 305, the second hinge seat 306 and the limit ring 304.

[0050] It should be noted that, under the premise that the first telescopic frame 302 and the second telescopic frame 303 can slide relative to each other and have a sufficient sliding distance, the cross-section of the first telescopic frame 302 and the second telescopic frame 303 at their sliding connection is rectangular, and the shape or structure of other positions may not be restricted.

[0051] In addition, under the premise that the first telescopic frame 302 and the second telescopic frame 303 can slide relative to each other and have a sufficient sliding distance, the cross-sections of the first telescopic frame 302 and the second telescopic frame 303 at their sliding connection can be adapted to each other, and can be regular or irregular shapes. That is, the cross-section of the second telescopic frame 303 is adapted to the structure of the cavity inside the first telescopic frame 302, and the outer dimension of the cross-section of the second telescopic frame 303 is slightly smaller than the cavity wall of the cavity inside the first telescopic frame 302, so that the two can be in a clearance fit.

The protective cover 900 is fixed to the side of the umbilical tower 1000 facing away from the rocket. That is, the protective cover 900 is fixed to the side of the umbilical tower 1000, and the protective cover 900 and the rocket are blocked by the umbilical tower 1000. When the folding frame 200 and the telescopic frame 300 are both in a folded state, and the telescopic frame 300 itself is in a shortened state, the protective cover 900 can surround the periphery of the base 100, the folding frame 200 and the telescopic frame 300. That is, the protective cover 900 can store the base 100, the folding frame 200 and the telescopic frame 300 inside it to prevent the impact and ablation of the rocket's takeoff tail flame, so that the main components of the air-conditioning connector retracting device can be reused, effectively reducing the cost of rocket launch.

[0053] In other embodiments of the present invention, the foldable and retractable device of the air conditioner connector further includes a lifting and rotating mechanism 400. The base 100 is fixedly connected to the lifting and rotating mechanism 400. The lifting and rotating mechanism 400 includes a spiral elevator 410 that can be lifted and lowered vertically and a rotating bearing 420 that is fixedly connected to the spiral elevator 410, and the rotating surface of the rotating bearing 420 is parallel to the radial surface of the rocket, so that the base 100 and the components connected to the base 100 can rotate horizontally. Relying on the lifting and rotating action of the lifting and rotating mechanism 400, the positions of the base 100, the folding frame 200 and the telescopic frame 300 can be adjusted, so that they can enter the protective cover 900 conveniently, thereby improving the convenience of use.
