Description

Technical Field

[0001] This utility model relates to the field of aerospace technology, and more specifically, to a solar panel substrate and a satellite. Background Technology

[0002] The solar panel substrate on a satellite plays a crucial role in supporting the solar cells, and its main function is to provide power to the satellite.

[0003] After the satellite is in orbit, the solar panel substrate needs to be deployed away from the satellite body to ensure that the solar panel is always facing the sun. Specifically, a rotating mechanism is installed on the solar panel substrate, and a lifting link is set between the rotating mechanism and the satellite body. The lifting link is connected to the rotating mechanism and is used to drive the solar panel substrate to be deployed away from the satellite body.

[0004] However, currently, the rotating mechanism is usually installed on the solar panel substrate using a flange end face conversion method. This installation method has the following problems: 1. Under limited space conditions, the rotating mechanism may not be able to be installed on the solar panel substrate; 2. After the rotating mechanism is installed on the solar panel substrate by means of flange end face conversion, it has the problem of weak rigidity, poor reliability, and high on-orbit safety risk. Utility Model Content

[0006] This utility model provides a solar panel substrate, comprising: a substrate body and a connecting assembly. A window is provided at the center of the substrate body, and the connecting assembly is used to install a rotating mechanism at the window. Two grooves are symmetrically provided on the inner wall of the window. The connecting assembly includes a U-shaped arm, a sleeve, and a shaft. The two shafts are respectively connected to the two ends of the rotating mechanism. The two U-shaped arms are respectively inserted into and fixed in the two grooves. The two sleeves are respectively connected to the ends of the two U-shaped arms, and the two sleeves are respectively sleeved with the two shafts.

[0007] The solar panel substrate provided by this utility model has the following beneficial effects compared with the prior art: The solar panel substrate of this invention features a rotating mechanism whose two ends are connected to the substrate body via U-shaped arms, sleeves, and shafts. This ensures the stability of the rotating mechanism's installation on the substrate body and improves the connection rigidity of the rotating mechanism. Each U-shaped arm is inserted into a groove in the substrate body, and the two grooves limit the position of the two U-shaped arms, preventing the rotating mechanism from swinging relative to or detaching from the substrate body. This facilitates subsequent fastening and securing of the U-shaped arms with fasteners. Furthermore, the sleeve and shaft connection ensures relative rotation and movement between the U-shaped arms and the rotating mechanism during installation, facilitating the installation of the U-shaped arms. Compared to related technologies, this solar panel substrate allows for effective installation of the rotating mechanism within limited space, and is more reliable and rigid than traditional flange installations, reducing on-orbit safety risks.

[0008] Optionally, the U-shaped arm includes a first arm, a second arm, and an intermediate connecting section, wherein the first arm and the second arm are respectively connected to the two ends of the intermediate connecting section, and the sleeve is connected to the middle position of the intermediate connecting section.

[0009] Optionally, the first arm and the second arm are respectively provided with a first connection hole, and the substrate body is provided with a second connection hole, and the second connection hole communicates with the groove. The first connection hole and the second connection hole are used to connect with screws to fix the U-shaped arm in the groove.

[0010] Optionally, the distance between the first arm and the second arm is greater than the thickness of the substrate body.

[0011] Optionally, the sleeve has a first positioning hole and the shaft has a second positioning hole. The first positioning hole and the second positioning hole are connected by a positioning pin to fix the shaft relative to the sleeve.

[0012] Optionally, the first positioning hole and / or the second positioning hole may have multiple holes.

[0013] Optionally, the length of the sleeve is the same as the length of the shaft.

[0014] Optionally, the depth of the groove is greater than the length of the U-shaped arm.

[0015] In addition, this utility model also provides a satellite, including a rotating mechanism and a solar panel substrate as described above.

[0016] Since the technological improvements and effects achieved by the satellite are the same as those of the solar panel substrate, the technical effects of the satellite will not be described in detail.

[0026] like Figures 1 to 8 As shown, the solar panel substrate of this utility model embodiment includes: a substrate body 1 and a connecting assembly. A window 11 is provided at the center of the substrate body 1. The connecting assembly is used to install the rotating mechanism 100 at the window 11. Two grooves 12 are symmetrically provided on the inner wall of the window 11. The connecting assembly includes a U-shaped arm 2, a sleeve 3 and a shaft 4. The two shafts 4 are respectively connected to the two ends of the rotating mechanism 100. The two U-shaped arms 2 are respectively inserted into and fixed in the two grooves 12. The two sleeves 3 are respectively connected to the ends of the two U-shaped arms 2, and the two sleeves 3 are respectively sleeved with the two shafts 4.

[0027] In this embodiment, in conjunction with the appendix Figure 1 To be continued Figure 8As shown, by connecting the rotating mechanism 100 to the window 11 of the substrate body 1, interference between the rotating mechanism 100 and other structures can be avoided, and the rotating mechanism can be installed on the solar panel substrate even under the premise of limited space.

[0028] During installation, first fix the base plate body 1, then rotate the left end of the rotating mechanism 100 (attached). Figure 2 The shaft 4 (in the positive X-axis direction) extends into the groove 12 on the left side of the window 11. Then, the U-shaped arm 2 at the right end is placed into the window 11, so that the U-shaped groove of the U-shaped arm 2 is inserted into the right edge of the window 11. Then, the U-shaped arm 2 is moved along the right edge of the window 11 until the sleeve 3 at its end is aligned with the shaft 4 at the right end of the rotating mechanism 100. That is, the sleeve 3 on the right end of the U-shaped arm 2 is adjusted to be approximately coaxial with the shaft 4 at the right end of the rotating mechanism 100. During this process, the substrate body 1 is located between the two arms of the right end of the U-shaped arm 2, as shown in the attached figure. Figure 2 As shown, the U-shaped arm 2 can be limited, which is beneficial for the alignment and adjustment of the U-shaped arm 2 and the shaft 4. Then, the sleeve 3 on the right end of the U-shaped arm 2 is moved towards the rotating mechanism 100, so that the shaft 4 and the sleeve 3 are completely engaged. Then, the right end of the U-shaped arm 2 is rotated 90 degrees, as shown in the attached figure. Figure 3 As shown, the rotating mechanism 100 and the right-end U-shaped arm 2 are then pushed to the right together until the right-end U-shaped arm 2 is pushed to the innermost side of the groove 12 on the right side of the window 11, as shown in the attached diagram. Figure 4 As shown, the left U-shaped arm 2 is then placed into the window 11 of the substrate body 1, and the U-shaped groove of the U-shaped arm 2 is inserted into the left edge of the window 11. Then, the U-shaped arm 2 is moved along the left edge of the window 11 until its end sleeve 3 is coaxially aligned with the shaft 4 at the left end of the rotating mechanism 100. At this time, the substrate body 1 is located between the two arms of the left U-shaped arm 2, as shown in the attached figure. Figure 5 As shown, the sleeve 3 on the left-end U-shaped arm 2 is then moved towards the rotating mechanism 100, so that the shaft 4 and the sleeve 3 are fully engaged. Then, the left-end U-shaped arm 2 is rotated 90 degrees, as shown in the attached figure. Figure 6 As shown, the rotating mechanism 100 and the U-shaped arm 2 at the left end are then pushed to the left together, so that the rotating mechanism 100 is in the middle position of the window 11, as shown in the attached figure. Figure 7 As shown, the U-shaped arms 2 at both ends are then fixed into the two grooves 12 using fasteners, for example, to complete the installation of the rotating mechanism 100, as shown in the attached figure. Figure 8 As shown.

[0029] In this embodiment, since the two ends of the rotating mechanism 100 are connected to the substrate body 1 through the U-shaped arm 2, the sleeve 3 and the shaft 4 respectively, the stability of the rotating mechanism 100 on the substrate body 1 can be guaranteed, and the connection rigidity of the rotating mechanism 100 on the substrate body 1 can be improved. The U-shaped arm 2 at each end is inserted into the groove of the substrate body 1. The two grooves limit the two U-shaped arms 2, which can prevent the rotating mechanism 100 from swinging relative to the substrate body 1 or detaching from the substrate body 1, so that the U-shaped arm 2 can be locked and fixed by fasteners. Furthermore, by using the sleeve 3 and the shaft 4, it can be ensured that the U-shaped arm 2 and the rotating mechanism 100 can rotate and move relative to each other during the installation process, so as to facilitate the installation of the U-shaped arm 2.

[0030] It should be noted that the groove on the substrate body 1 can be a rectangular hole structure with one end open (groove). This groove includes four sidewalls, the width of which can be adapted to the width of the U-shaped arm 2. After the U-shaped arm 2 extends into the groove, the groove can be positioned along the length of the substrate body 1 (see attached diagram). Figure 2 (in the Y-axis direction) and thickness direction (attached) Figure 2 The U-shaped arm 2 is limited along the Z-axis direction, thus increasing its rigidity when fixed in the groove by fasteners. Additionally, in conjunction with the attached... Figure 2 As shown, the width of window 11 (see attached diagram) Figure 2 The length of the rotating mechanism 100, sleeve 3, and shaft 4 (in the X-axis direction) should be at least greater than the sum of their lengths to avoid installation interference.

[0034] Optionally, the first arm 21 and the second arm 22 are respectively provided with a first connecting hole 24, and the substrate body 1 is provided with a second connecting hole 13, and the second connecting hole 13 communicates with the groove 12.

The first connecting hole 24 can be a threaded hole. A second connecting hole 13 is provided on the substrate body 1. The second connecting hole 13 can be a threaded hole and communicates with the groove 12.

[0036] Optionally, the distance between the first arm 21 and the second arm 22 is greater than the thickness of the substrate body 1.

[0037] In this embodiment, in conjunction with the appendix Figure 2 Or attached Figure 5 As shown, the distance between the first arm 21 and the second arm 22 of the U-shaped arm 2 is greater than the thickness of the substrate body 1.

[0044] Optionally, the depth of the groove 12 is greater than the length of the U-shaped arm 2.

[0045] In this embodiment, in conjunction with the appendix Figure 4 As shown, the depth of the groove 12 is designed to be greater than the length of the U-shaped arm 2, so that the sleeve 3 and the shaft 4 can extend into the groove 12, leaving more space to ensure that the rotating mechanism 100 can be smoothly installed on the base plate body 1.
