Detailed Implementation

[0024] The embodiments of the technical solution of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the technical solution of the present invention and are therefore intended to limit the scope of protection of the present invention.

[0025] It should be noted that, unless otherwise stated, the technical or scientific terms used in this application should have the ordinary meaning as understood by one of ordinary skill in the art to which this invention pertains.

[0026] like Figures 1 to 3 As shown in the figure, 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 deployed or folded. Specifically, it includes a hinge body 100 and a solar panel holder 200. The hinge body 100 has hinge platforms 110 at both ends, and the solar panel holder 200 has connecting platforms 210 at both ends. The hinge platforms and connecting platforms 210 are connected by a rotary joint 300, which allows the solar panel holder 200 to rotate around the hinge platform 110. The rotary joint 300 is fitted with a hinge torsion spring 400 that cooperates with the hinge platform 110 and the connecting platform 210. One of the connecting platforms 210 also has a timing torsion spring 500 at its outer end, and the end of the timing torsion spring 500 has a control section 510 that is fixed to the solar panel holder 200.

[0027] like Figures 1 to 3As shown, through the above setting, the sailboard fixer 200 for installing the solar sailboard in the embodiment is connected with the hinge body 100 through the rotary joint 300, the solar sailboard can rotate around the rotary joint 300 to realize unfolding or folding, so as to realize flexible rotary connection between the solar sailboard and the satellite body and support the secondary unfolding requirement of the solar sailboard. Since the timing torsion spring 500 is arranged on one of the connecting tables 210, the control section 510 of the timing torsion spring 500 is connected with the sailboard fixer 200, which can generate a certain torsion on the hinge unfolding, so as to ensure that the first layer of sailboard is completely unfolded and reaches the predetermined position, and then the second layer of sailboard is allowed to start unfolding, so as to prevent interference and collision in the unfolding process. In order to install the timing torsion spring 500 on the connecting table 210, the connecting table 210 on which the timing torsion spring 500 is installed is connected with a torsion spring bracket 900 at the outer end, the timing torsion spring 500 is sleeved on the mounting portion arranged at the end of the torsion spring bracket 900, and a loose jaw clamp 1000 for fixing the timing torsion spring is arranged at the end of the mounting portion. In this way, the timing torsion spring can be installed through the torsion spring bracket and prevented from falling off under the fixing action of the loose jaw clamp.

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

[0029] As shown in Figures 1 to 3 In order to connect the rotary joint 300 with the hinge table 110 and the connecting table 210, one mounting head 600 of the rotary joint 300 is connected with the hinge hole 111 arranged on the hinge table 110, and the other mounting head 600 is connected with the connecting hole 211 arranged on the connecting table 210. In this way, the rotary joint 300 can be connected with the hinge hole 111 and the connecting hole 211 through the mounting head 600.

[0030] As shown in Figures 1 to 3 The hinge torsion spring 400 arranged on the rotary joint 300 needs to be matched with the hinge table 110 and the connecting table 210, and the embodiment is provided with a fixed hole 700 for fixing the spring leg of the hinge torsion spring 400 outside the hinge table 110 and the connecting table 210. In this way, the spring leg of the hinge torsion spring 400 can be inserted into the corresponding fixed hole 700, so as to generate torsion and ensure that the hinge body 100 and the sailboard fixer 200 are connected in a hinge type.

[0031] As shown in 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 solar panel fixer 200 away from the hinge body 100; the connecting part 220 can be used to connect the solar panel structure to ensure that the solar panel is stably installed.

[0032] like Figures 1 to 3 As shown, in practical applications, the solar panel needs to be deployed and rotated to a fixed position. This embodiment also provides a limiter to restrict the deployment 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 longitudinal direction of the solar panel holder 200. After the solar panel holder 200 is deployed around the hinge platform 110, the solar panel holder 200 can abut against the limit rod. In this way, when the solar panel is deployed, the solar panel holder 200 can abut against the limit rod. The angle limiter structure ensures the accuracy of the solar panel deployment angle and prevents equipment damage caused by over-deployment or under-deployment. The limiter is specifically designed to control the solar panel deployment angle, and different specifications of limiters can be replaced according to deployment needs.

[0033] Example 2

[0034] like Figures 1 to 4 As shown, this embodiment further optimizes the solar panel mounting hinge device by integrating an exhaust structure, thereby enabling the connection of pipelines to implement efficient heat dissipation or exhaust actions. Specifically, an exhaust valve 1200 is provided on the end face of one hinge platform 110. 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. An exhaust groove 1230 is provided on the side wall of the exhaust channel 1210. A sealing screw 1300 is screwed into the opening of the exhaust channel 1210. The sealing screw 1300 can close the exhaust channel 1210. When the sealing screw 1300 rotates, it can connect the exhaust groove 1230, the connecting channel 1220, and the exhaust channel 1210.

[0035] In order to make the rotary joint 300 communicate with the communication channel 1220, the connecting head in the embodiment is hollowly arranged at the end of the rotary joint 300; in order to install the exhaust valve 1200 at the end face of the hinged table 110, the embodiment is provided with an insertion section 1240 inserted into one of the hinged holes 111 of the end face of the hinged table 110 at the end of the exhaust valve 1200 away from the exhaust groove 1230, and the outer periphery of the exhaust valve 1200 is provided with a sealing ring protrusion 1250 arranged around the insertion section 1240, and the sealing ring protrusion 1250 is provided with a ring groove 1260 arranged around the insertion section 1240 corresponding to the side wall of one side of the insertion section 1240, and the ring groove 1260 is provided with an outer sealing ring. In this way, when the insertion section 1240 is inserted into the mounting hole, the outer sealing ring plays a sealing mounting role, and at the same time, the inner sealing ring is arranged in the exhaust channel 1210, and the end face of the sealing screw 1300 is in contact with the inner sealing ring when the sealing screw 1300 seals the exhaust channel 1210. Ensure that the sealing screw 1300 has better sealing effect when sealing the exhaust channel 1210; in production application, the exhaust valve 1200 is made of high-strength and high-temperature-resistant polyimide material, which not only has excellent mechanical properties and thermal stability, can maintain structural stability at extreme temperatures (-200℃ to +300℃), but also allows light to penetrate due to its translucent property, facilitating observation of the internal state of the pipeline and improving maintenance efficiency and troubleshooting speed. The outer sealing ring and the inner sealing ring 7 are both made of high-elasticity, anti-aging silicone rubber or similar materials, ensuring that they still maintain good sealing performance under extreme temperature and pressure changes. The sealing screw 1300, as a device for opening and closing the exhaust channel 1210, controls the gas discharge through rotational adjustment, and uses high-strength alloy material to ensure that it has sufficient strength.

[0036] When the entire device is in use, the hinge structure is connected to the exhaust or liquid discharge pipeline on the satellite heat dissipation radiation plate through the connecting hole 211 on the connecting table 210, realizing efficient heat transfer and dissipation and discharging the air in the pipeline, ensuring the smoothness of liquid flow. Through the design of the exhaust valve 1200, the thermal management efficiency of the satellite is improved, ensuring that the internal equipment of the satellite operates at an appropriate temperature.
