The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and are therefore only used as examples, and cannot be used to limit the protection scope of the present invention.

[0025] It should be noted that, unless otherwise specified, the technical terms or scientific terms used in this application should have the common meanings understood by those skilled in the art to which the present invention belongs.

[0026] like Figures 1 to 3 As shown, a specific embodiment of the present invention provides a solar panel mounting rotary hinge device, which is used to connect a satellite and a solar panel to ensure that the solar panel can be stably unfolded or folded; it specifically includes a hinge body 100 and a panel holder 200; hinge bodies 110 are provided at both ends of the hinge body 100, connecting platforms 210 are provided at both ends of the panel holder 200, and the hinge bodies and connecting platforms 210 are connected by a rotary joint 300, so that the panel holder 200 can rotate around the hinge bodies 110, and the rotary joint 300 is provided with a hinge torsion spring 400 that cooperates with the hinge bodies 110 and the connecting platforms 210; a timing torsion spring 500 is also provided at the outer end of one of the connecting platforms 210, and a control section 510 fixed to the panel holder 200 is provided at the end of the timing torsion spring 500.

[0027] like Figures 1 to 3As shown, through the above arrangement, the panel holder 200 for installing the solar panel in this embodiment is hingedly matched with the hinge body 100 through the rotating joint 300, and the solar panel can be rotated around the rotating joint 300 to be unfolded or folded, thereby realizing a flexible rotation connection between the solar panel and the satellite body, and supporting the secondary unfolding requirement of the solar panel. Since a timing torsion spring 500 is provided on one of the connecting platforms 210, the control section 510 of the timing torsion spring 500 is connected to the windsurfing board holder 200, and can generate a certain torque for the hinge to unfold, thereby ensuring through torque control that the first layer of windsurfing board is fully unfolded and reaches a predetermined position before the second layer of windsurfing board is allowed to begin to unfold, thereby preventing interference and collision during the unfolding process. In order to install the timing torsion spring 500 on the connecting platform 210, a torsion spring bracket 900 is connected to the outer end of the connecting platform 210 on which the timing torsion spring 500 is installed, and the timing torsion spring 500 is sleeved on a mounting portion provided at the end of the torsion spring bracket 900, and a movable clamp 1000 for fixing the timing torsion spring is provided at the end of the mounting portion, so that the timing torsion spring can be installed through the torsion spring bracket, and it is prevented from falling off under the fixing action of the movable clamp.

[0028] like Figures 1 to 3 As shown, in actual application, the hinge body 100 and each structure on the sailboard fixture 200 are made of light and high-strength materials, so that the device can be reliably connected to the solar sailboard after being fixedly installed on the side of the satellite structure frame.

[0029] like Figures 1 to 3 As shown, in order to connect the rotary joint 300 with the hinged platform 110 and the connecting platform 210, the present embodiment has mounting heads 600 at both ends of the rotary joint 300, one mounting head 600 is connected to the hinged hole 111 provided on the hinged platform 110, and the other mounting head 600 is connected to the connecting hole 211 provided on the connecting platform 210. In this way, the rotary joint 300 can be connected to the hinged hole 111 and the connecting hole 211 through the mounting heads 600.

[0030] like Figures 1 to 3 As shown, the hinge torsion spring 400 provided on the rotary joint 300 needs to cooperate with the hinge platform 110 and the connecting platform 210. In this embodiment, a fixing hole 700 for fixing the spring foot of the hinge torsion spring 400 is provided on the outer side of the hinge platform 110 and the connecting platform 210. In this way, the spring foot of the hinge torsion spring 400 can be inserted into a corresponding fixing hole 700, thereby generating a torsion force to ensure that the hinge body 100 and the windsurfing fixture 200 form a hinged assembly.

[0031] like Figures 1 to 3As shown, this embodiment also provides fixing plates 120 at both ends of the hinge body 100, and the hinge body 100 can be installed on the outside of the satellite body through the fixing plates 120; at the same time, this embodiment also provides a connecting part 220 for connecting the solar panel on the side of the panel holder 200 away from the hinge body 100; the connecting part 220 can be used to connect the solar panel structure to ensure that the panel is stably installed.

[0032] like Figures 1 to 3 As shown, in actual application, the solar panel needs to be unfolded and rotated to a fixed position. This embodiment also provides a limiter for limiting the unfolding angle of the solar panel. The limiter includes a limit block 800 fixed to the outside of the hinge body 100. The limit block 800 is provided with a limit rod arranged along the length of the sailboard fixture 200. After the sailboard fixture 200 is unfolded around the hinge platform 110, the sailboard fixture 200 can be against the limit rod. In this way, when the solar panel is unfolded, the sailboard fixture 200 can be against the limit rod. The angle limiter structure ensures the accuracy of the unfolding angle of the sailboard and prevents equipment damage caused by over-expansion or under-expansion. The limiter is specially designed to control the unfolding angle of the sailboard. Limiters of different specifications can be replaced according to the unfolding needs.

[0033] Embodiment 2

[0034] like Figures 1 to 4 As shown, the present embodiment further optimizes the solar panel mounting rotary hinge device and integrates an exhaust structure, so that the pipeline can be connected to implement efficient heat dissipation or exhaust action; specifically, an exhaust valve 1200 is provided on the end face of one of the hinged platforms 110, and the exhaust valve 1200 has an exhaust channel 1210 and a connecting channel 1220 that are interconnected. The connecting channel 1220 is connected to the connecting platform 210 through a rotary joint 300, and an exhaust groove 1230 is provided on the side wall of the exhaust channel 1210. The opening of the exhaust channel 1210 is screwed with a sealing screw 1300, and the sealing screw 1300 can close the exhaust channel 1210. When the sealing screw 1300 rotates, the exhaust groove 1230, the connecting channel 1220 and the exhaust channel 1210 can be connected.

[0035] In order to make the rotary joint 300 communicate with the communication channel 1220, the connector installed at the end of the rotary joint 300 in this embodiment is arranged hollow; in order to install the exhaust valve 1200 on the end face of the hinged platform 110, an insertion section 1240 is provided at the end of the exhaust valve 1200 away from the exhaust groove 1230, which is inserted into one of the hinge holes 111 on the end face of the hinged platform 110. The outer periphery of the exhaust valve 1200 is provided with a sealing ring protrusion 1250 arranged around the insertion section 1240. The side wall of the sealing ring protrusion 1250 corresponding to the side of the insertion section 1240 is provided with an annular groove 1260 arranged around the insertion section 1240, and an outer sealing ring is provided in the annular groove 1260. In this way, when the insertion section 1240 is inserted into the installation hole, the outer sealing ring plays a role in sealing and installing. At the same time, an inner sealing ring is provided in the exhaust channel 1210. When the sealing screw 1300 seals the exhaust channel 1210, its end face contacts the inner sealing ring. Ensure that the sealing screw 1300 has a better sealing effect when sealing the exhaust channel 1210; in production applications, the exhaust valve 1200 is made of high-strength, high-temperature-resistant polyimide material, which not only has excellent mechanical properties and thermal stability, and can maintain structural stability at extreme temperatures (-200°C to +300°C), but also because of its translucent properties, allows light to penetrate, making it easy to observe the internal state of the pipeline, improving maintenance efficiency and troubleshooting speed. The outer sealing ring and the inner sealing ring 7 are both made of highly elastic, aging-resistant silicone rubber or similar materials to ensure that good sealing performance is maintained under extreme temperature and pressure changes. The sealing screw 1300 is a device for opening and closing the exhaust channel 1210. It controls gas emissions through rotation adjustment, and uses high-strength alloy materials to ensure that it has sufficient strength.

[0036] When the whole device is in use, the hinge structure is connected to the exhaust or liquid discharge pipeline on the satellite heat radiation plate through the connection hole 211 on the connection platform 210, so as to realize the efficient transmission and dissipation of heat and exhaust the air in the pipeline to ensure the smooth flow of liquid. The design of the exhaust valve 1200 improves the thermal management efficiency of the satellite and ensures that the internal equipment of the satellite operates at a suitable temperature.
