During the launch phase of the spacecraft, the pod rod is stored in a coiled attitude inside the spacecraft, and is deployed into a long straight rod shape for supporting the spacecraft equipment. Since the pod rod stores elastic strain energy when coiled, the pod rod is generally guided to deploy in one direction under the action of elastic strain energy, but the elastic strain energy is uncontrollable, and the pod rod is prone to loose coil phenomenon due to its own restoring force during deployment, at which time the pod rod will deploy under coiling, resulting in disordered deployment of the pod rod, affecting use, and even causing damage to the pod rod.

[0057] The pod rod 3 is a widely used elastic support structure, named for its double-Ω closed cross-section, which resembles a peapod. This structure offers good load-bearing rigidity. Flattening its cross-section significantly reduces its bending stiffness, allowing it to be easily rolled up and wrapped around the roller 2 for folding. Upon release, the unconstrained portion automatically rebounds to its original cross-sectional shape, allowing it to unfold.

[0058] In view of the shortcomings of the existing technology, this embodiment provides a lightweight pod pole self-deployment mechanism based on damping control, which can be specifically described as follows:

[0059] As attached Figure 1 , Attachment Figure 2 and attached Figure 4 As shown, a lightweight pod rod self-expanding mechanism based on damping control includes a fixed bracket 1, a roller 2 rotatably set on the fixed bracket 1, a pod rod 3, two first flexible Velcros 31 and two second flexible Velcros 32. The roller 2 is rotatably set on the fixed bracket 1, and the pod rod 3 is wound around the surface of the roller 2 for winding. The pod rod 3 can be unfolded by rotating the roller 2. Two first flexible Velcros 31 are symmetrically set on one side of the pod rod 3, and two second flexible Velcros 32 are symmetrically set on the other side. The two first flexible Velcros 31 and the two second flexible Velcros 32 are symmetrically set. The first flexible Velcro 31 and the second flexible Velcro 32 correspond to each other one by one, and can cooperate with each other to be fastened together. After the pod rod 3 is flattened, it is wrapped around the surface of the drum 2, so that the first flexible Velcro 31 on one side of the pod rod 3 and the second flexible Velcro 32 on the other side are fastened to each other, preventing the pod rod 3 from unfolding under elastic potential energy, and can be better wrapped around the surface of the drum 2. When the pod rod 3 is unfolded, the action of the first flexible Velcro 31 and the second flexible Velcro 32 can effectively prevent the pod rod 3 from loosening under the action of its own elastic potential energy and bouncing open, thereby avoiding damage to the pod rod 3.

[0060] Further, the drum 2 is hollowed out to reduce the mass of the mechanism, and the circumferential surface of the drum 2 can be provided with a third flexible hook-and-loop fastener. After the side wall of the bean pod rod 3 near the surface of the drum 2 is flattened, the first flexible hook-and-loop fastener 31 on this side is attached to the third flexible hook-and-loop fastener on the drum 2. By cooperating the first flexible hook-and-loop fastener 31 with the third flexible hook-and-loop fastener, the bean pod rod 3 can be pulled horizontally to prevent it from bouncing up due to elastic potential energy. The side of the bean pod rod 3 near the drum 2 is held against the inner wall of the drum 2. When the bean pod rod 3 is wound, the adjacent surfaces of the bean pod rod 3 are separated under the action of the first flexible hook-and-loop fastener 31 and the second flexible hook-and-loop fastener 32, thereby relieving stress concentration and buckling instability.

[0061] As shown in Figs. 1-3, Figure 1 , Figs. 4-6, Figure 3 and Figs. 7-9, Figure 5 a fixed support 1 is provided with a guide mechanism 4 on one side for guiding the expansion of the bean pod rod 3.

A damping rod 51 is arranged inside the damper 5 and fixedly connected to the fixed support 1. By rotating the drum 2, the damper 5 rotates around the damping rod 51. At this time, the damping rod 51 applies a damping force to the damper 5. The double-wheel pressing mechanism 6 is arranged on the side of the fixed support 1 away from the guide mechanism 4 to press the bean pod rod 3 and prevent it from bouncing back to the original state due to elastic potential energy. The double-wheel pressing mechanism 6 also separates the first flexible hook-and-loop fastener 31 from the second flexible hook-and-loop fastener 32. At the same time, the elastic force of the bean pod rod 3 is applied to the drum 2 by the double-wheel pressing mechanism 6, causing the drum 2 to rotate. The bean pod rod 3 expands in one direction.

[0062] When the bean pod rod 3 is not in use, it is wound onto the surface of the drum 2, and the end of the bean pod rod 3 away from the drum 2 is fixed. Under the action of the first flexible hook-and-loop fastener 31, the second flexible hook-and-loop fastener 32, the damper 5, and the double-wheel pressing mechanism 6, the drum 2 is fixed, and the bean pod rod 3 is in a fixed state.

[0076] When the drum 2 drives the damper 5 to rotate, the damping groove 54 inside the damper 5 rotates, and the vane 52 is extruded to expand and contract through the cam shape of the damping groove 54. The viscous liquid is extruded by the damping groove 54 and adheres to the side wall of the damping groove 54, generating a certain viscous friction force. The damping force is provided by the expansion and contraction of the vane 52 and the viscous liquid, so that the drum 2 is subjected to a certain damping force when rotating, preventing the drum 2 from rotating too fast under the action of the pod pole 3 and being uncontrollable.

[0077] Further, the viscous liquid is dimethyl silicone oil with a certain viscosity.

[0078] Other embodiments of the application will be apparent to those skilled in the art from consideration of the specification and practice of the aspects disclosed herein. The specification and examples given are exemplary only. It is intended to cover any variations, uses, or adaptations of the application following, in general, the principles of the application and including such departures from the present disclosure as come within known or customary practice in the art to which the application pertains. The true scope and spirit of the application are indicated by the claims.
