Description

Technical Field

[0001] This utility model relates to the field of solar array deployment technology, specifically a satellite solar array and deployment mechanism. Background Technology

[0002] Satellite solar panels, also known as solar cell wings or solar panel wings, are devices used in space to collect solar energy. They typically consist of multiple solar panels that convert solar energy into electricity for the satellite's use. The primary function of satellite solar panels is to provide power to the satellite, but they can also power other satellite systems, such as communication, navigation, and scientific instruments. The deployment mechanism of the satellite solar panels plays a crucial role in the satellite's launch and operation. The deployment of the solar panels is a critical step for the satellite to enter its operational state. If the solar panels cannot deploy, the satellite will lose its operational capability as its remaining battery energy gradually decreases, severely impacting its on-orbit lifespan. Therefore, the deployment mechanism of the satellite solar panels is a key component ensuring the normal operation of the satellite. To reduce the failure rate of the solar panel deployment structure, a simple structure and a smooth deployment process are required. Therefore, a satellite solar panel and its deployment mechanism are proposed. Utility Model Content

Example

[0024] Please see Figure 1-6 This utility model provides a technical solution: a satellite solar array and deployment mechanism, including a satellite body 1, two fixed frames 2 are installed on both sides of the satellite body 1, and a solar array assembly is arranged between the two fixed frames 2; the solar array assembly includes two mounting bases 3 and a plurality of solar panels 16, the two mounting bases 3 are respectively installed between the two fixed frames 2, the plurality of solar panels 16 are installed on the mounting bases 3, and a deployment assembly is arranged inside the mounting bases 3;

[0025] By setting up an unfolding assembly, the failure rate of solar panel 16 unfolding is effectively reduced. The unfolding assembly includes a rotating shaft 6 and several connecting plates 15. A groove 4 is provided on one side of the mounting base 3, and several sliding grooves 5 are provided on the outer side of the mounting base 3. The rotating shaft 6 is rotatably connected to the bottom of the groove 4, and a limit assembly is provided on the outer side of the rotating shaft 6. Several connecting plates 15 are slidably connected to the interior of several sliding grooves 5. The rotating shaft 6 drives one connecting plate 15 to rotate and move within the sliding groove 5, thereby driving one solar panel 16 to rotate on the outer side of the mounting base 3.

[0026] The limiting assembly includes a first slip ring 7, a second slip ring 8, and a third slip ring 9. The first slip ring 7 is fixedly connected to the bottom of the groove 4 and located outside the rotating shaft 6. The second slip ring 8 is fixedly connected to the bottom of the groove 4 and displaced outside the first slip ring 7. The third slip ring 9 is fixedly connected to the bottom of the groove 4 and located outside the second slip ring 8. A fourth slip ring 10 is fixedly connected to the bottom of the groove 4 outside the third slip ring 9. A first sliding post 11, a second sliding post 12, and a third sliding post 13 are slidably connected to the outer sides of the first slip ring 7, the second slip ring 8, and the third slip ring 9, respectively. A fourth sliding post 14 is fixedly connected to the outer side of the fourth slip ring 10. Four connecting plates 15 are fixedly connected to one end of the first sliding post 11, the second sliding post 12, the third sliding post 13, and the fourth sliding post 14, respectively. One end of each connecting plate 15 is connected to one end of the solar panel 16. The connecting plates 15 are fixedly connected to the rotating shaft 6. One end of the connecting plate 15 on the outer side of shaft 6 is connected to the end of the solar panel 16 away from the bottom of groove 4. A connecting strap 17 is provided between two adjacent connecting plates 15. One end of the connecting strap 17 is fixedly connected to one side of the upper connecting plate 15, and the other end of the connecting strap 17 is fixedly connected to the other side of the lower connecting plate 15. One connecting plate 15 rotates and moves inside the slide groove 5, thereby driving one solar panel 16 to rotate outside the mounting base 3. During this process, the movement of one connecting plate 15 drives one end of the connecting strap 17 to move. Thus, when the top solar panel 16 is detached from the top of the lower solar panel 16, one connecting plate 15 pulls the lower connecting plate 15 through the connecting strap 17, thereby pulling the lower solar panel 16 to move, thus unfolding several solar panels 16, which facilitates the unfolding and use of several solar panels 16.

[0027] A drive motor 18 is installed on the side of the mounting base 3 away from the groove 4. The output shaft of the drive motor 18 is fixedly connected to one end of the rotating shaft 6. By controlling the start of the drive motor 18, the output shaft of the drive motor 18 drives the rotating shaft 6 to rotate, so that the rotating shaft 6 drives a connecting plate 15 to rotate and move inside the slide groove 5. The drive motor 18 is a brake motor.

[0028] The working principle or structural principle is as follows: When the solar panel needs to be used, the drive motor 18 is started by controlling it. The output shaft of the drive motor 18 drives the rotating shaft 6 to rotate, which causes the rotating shaft 6 to drive a connecting plate 15 to rotate and move inside the slide groove 5. This causes a solar panel 16 to rotate on the outside of the mounting base 3. During this process, the movement of the connecting plate 15 causes one end of the connecting belt 17 to move. Thus, when the top solar panel 16 is separated from the bottom solar panel 16, the connecting plate 15 pulls the bottom connecting plate 15 to move through the connecting belt 17, thereby pulling the bottom solar panel 16 to move. This unfolds several solar panels 16, making it convenient to unfold and use several solar panels 16. The structure is simple, effectively reducing the failure rate of unfolding the solar panels 16. Moreover, the unfolding of several solar panels 16 can be completed by the drive motor 18.

In particular, the features described in the various embodiments and / or claims of this utility model can be combined or combined in various ways without departing from the spirit and teachings of this utility model.
