Description

Technical Field

[0001] The utility model relates to the technical field of hinges, and in particular to a solar panel mounting rotary hinge device. Background Art

[0002] With the continuous development of aerospace technology, the energy demand of spacecraft is increasing. As the primary energy supply device for spacecraft, the performance of solar panels directly affects the operating efficiency and lifespan of spacecraft. Traditional solar panel deployment mechanisms often suffer from large size, heavy weight, complex structure, high cost, and the risk of interference and damage due to simultaneous deployment of panels.

[0003] Therefore, developing a new type of solar panel secondary deployment hinge to achieve a safer, more efficient and economical solar panel deployment process has become a technical problem that needs to be urgently solved in the current aerospace technology field. Utility Model Content

[0004] In response to the defects in the existing technology, the purpose of the present invention is to provide a solar panel mounting rotary hinge device that can stably install solar panels, has strong bearing capacity and simple structure, and can avoid damage to the panels due to interference when they are unfolded.

[0005] The technical solution adopted by the utility model is: a solar panel mounting rotary hinge device, including a hinge body and a panel holder; hinge platforms are provided at both ends of the hinge body, and connecting platforms are provided at both ends of the panel holder, and the hinge platforms and the connecting platforms are connected by a rotary joint so that the panel holder can rotate around the hinge platform, and the rotary joint is provided with a hinge torsion spring that cooperates with the hinge platform and the connecting platform; the outer end of one of the rotary joints is also provided with a timing torsion spring arranged along the axial direction of the rotary joint, and the end of the timing torsion spring is provided with a control section fixed to the panel holder.

[0006] In this technical solution, the panel holder used to mount the solar panels is hinged to the hinge body via a rotary joint. The solar panels can be deployed or retracted by rotating around the rotary joint, thus achieving a flexible rotational connection between the solar panels and the satellite body and supporting the need for secondary deployment of the solar panels. Because a timed torsion spring is installed on one of the rotary joints, torque control ensures that the first layer of panels is fully deployed and reaches the predetermined position before the second layer of panels can begin to deploy, preventing interference and collisions during deployment.

[0007] Preferably, mounting heads are provided at both ends of the rotary joint, one of the mounting heads is connected to a hinge hole provided on the hinge platform, and the other mounting head is connected to a connection hole provided on the connection platform.

[0008] Preferably, fixing holes for fixing the spring legs of the hinge torsion springs are provided on the outer sides of the hinge platform and the connecting platform.

[0009] Preferably, fixing plates are provided at both ends of the hinge body.

[0010] Preferably, a connecting portion for connecting to the solar panel is provided on a side of the windsurfing panel holder away from the hinge body.

[0011] Preferably, a limiter is further included, which includes a limit block fixed to the outside of the hinge body, and the limit block is provided with a limit rod arranged along the length of the windsurfing board holder. After the windsurfing board holder is unfolded around the hinge platform, the windsurfing board holder can be against the limit rod.

[0012] The beneficial effects of the present invention are as follows: the present invention has a compact structure and is fixedly mounted on the side of a satellite structure frame, enabling reliable connection with the sailboard; at the same time, the rotary joint for rotating the sailboard is built into the hinge body, enabling a flexible rotational connection between the sailboard and the satellite body, supporting the secondary deployment requirements of the sailboard. A timing control structure is also provided within the hinge to prevent interference and collision during the deployment process. When installing the sailboard, this device can limit the deployment angle of the sailboard, ensuring that the deployment angle of the sailboard meets the design requirements and preventing over- or under-deployment. It can be applied in the field of satellite manufacturing and has high practical value. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0018] The following embodiments of the technical solution of the present invention are described in detail with reference to the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention and are therefore only examples and are not intended to limit the scope of protection of the present invention.

[0019] 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 this utility model belongs.

[0020] 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; a hinge platform 110 is provided at both ends of the hinge body 100, and a connecting platform 210 is provided at both ends of the panel holder 200. The hinge platform and the connecting platform 210 are connected by a rotary joint 300, so that the panel holder 200 can rotate around the hinge platform 110, and the rotary joint 300 is provided with a hinge torsion spring 400 that cooperates with the hinge platform 110 and the connecting platform 210; the outer end of one of the rotary joints is also provided with a timing torsion spring 500 arranged along the axial direction of the rotary joint, and the end of the timing torsion spring 500 is provided with a control section 510 fixed to the panel holder 200.

[0021] like Figures 1 to 3 As shown, through the above arrangement, the panel holder 200 for mounting a solar panel in this embodiment is hingedly connected to the hinge body 100 via a rotary joint 300. The solar panel can be rotated about the rotary joint 300 to be deployed or folded, thereby achieving a flexible rotational connection between the solar panel and the satellite body and supporting the secondary deployment of the solar panel. Because a timing torsion spring 500 is provided on one of the rotary joints 300, the control section 510 of the timing torsion spring 500 is connected to the panel holder 200, which can generate a certain torque to deploy the hinge. This torque control ensures that the first layer of panels is fully deployed and reaches the predetermined position before the second layer of panels is allowed to begin deploying, preventing interference and collision during the deployment process.

[0022] like Figures 1 to 3 As shown, in actual application, the hinge body 100 and each structure on the sailboard holder 200 are made of lightweight 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.

[0023] like Figures 1 to 3As shown, in order to connect the rotary joint 300 to the articulation platform 110 and the connection platform 210, this embodiment has mounting heads 600 at both ends of the rotary joint 300. One mounting head 600 is connected to the articulation hole 111 provided on the articulation platform 110, and the other mounting head 600 is connected to the connection hole 211 provided on the connection platform 210. In this way, the rotary joint 300 can be connected to the articulation hole 111 and the connection hole 211 through the mounting heads 600.

[0024] 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, fixing holes 700 for securing the spring legs of the hinge torsion spring 400 are provided on the outside of the hinge platform 110 and the connecting platform 210. Thus, the spring legs of the hinge torsion spring 400 can be inserted into corresponding fixing holes 700, thereby generating a torsional force to ensure that the hinge body 100 and the windsurfing fixture 200 form a hinged assembly.

[0025] like Figures 1 to 3 As 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 portion 220 for connecting the solar panel on the side of the panel holder 200 away from the hinge body 100; the connecting portion 220 can be used to connect the solar panel structure to ensure that the panel is stably installed.

[0026] like Figures 1 to 3 As shown, in actual applications, the solar panel needs to be unfolded and rotated to a fixed position. This embodiment also provides a limiter for limiting 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 length of the panel holder 200. After the panel holder 200 is unfolded around the hinge platform 110, the panel holder 200 can abut against the limit rod. In this way, when the solar panel is unfolded, the panel holder 200 can abut against the limit rod. The angle limiter structure ensures the accuracy of the panel deployment angle and prevents equipment damage caused by over- or under-deployment. The limiter is specially designed to control the deployment angle of the panel, and limiters of different specifications can be replaced according to deployment needs.

[0027] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or replace some or all of the technical features therein with equivalents. These modifications or replacements do not deviate the essence of the corresponding technical solutions from the scope of the technical solutions of the embodiments of the present invention, and they should all be included in the scope of the claims and description of the present invention.
