[0002] Since the 21st century, the space competition has become increasingly fierce, and the demand for microsatellites has also been growing strongly. Musk's Starlink project is expected to consist of tens of thousands of microsatellites. With the gradual implementation of this project, the microsatellite industry has entered a stage of rapid development. At the same time, the traditional single-satellite research and production method can no longer meet the current satellite development status, and microsatellites need to adopt mass production methods to meet the market demand for the number of satellites.

[0003] Currently, limited by the style of the satellite structural plate, when assembling the satellite structural plate, the manual installation method is mainly adopted. Moreover, due to the large number of screws to be installed, usually many people need to cooperate to install them together, which not only leads to an increase in labor costs but also an increase in the satellite production time. Therefore, the existing style of the satellite structural plate is not conducive to assembling satellites using an automated production line. Summary of the Invention

[0027] In order to better understand the above technical solution, the following will combine the specification drawings and specific implementation modes to make a detailed description of the above technical solution.

[0028] As Figures 1-6 shown, an embodiment of the present invention provides a microsatellite structural plate system applicable to an automated production line, including: a structural plate 1, a reinforcing bar 2, and a fixing bolt 3;

[0029] Mortise and tenon structures are provided on each side of the structural plate 1 (see Figure 3 ), the structural plates 1 are mortise and tenon connected (see Figure 1 ), the reinforcing bar 2 (see Figure 4 , 5 ) is embedded at the mortise and tenon connection of two adjacent structural plates 1 (see Figure 2 ), and both ends of the reinforcing bar 2 are connected to the two structural plates 1 through the fixing bolt 3 (see Figure 2 ).

[0030] Among them, as Figure 3 shown, the mortise and tenon structures on each side of the structural plate include a tenon 6 (tenon) and a mortise 7 (mortise). During use, the connection between the structural plates is realized through the connection of the tenon and the mortise. Since the mortise and tenon connection is relatively firm, therefore, when installing the structural plates, that is, connecting the structural plates, it is not necessary to use too many fixing bolts for fastening to realize a relatively firm connection between the structural plates.

[0031] In order to further strengthen the connection firmness between the structural plates, the structural plate system provided by the present invention further includes a reinforcing bar and a fixing bolt. During use, after connecting and fixing two structural plates through the mortise and tenon structure, the reinforcing bar is embedded and installed on the mortise and tenon connection line of the two structural plates, and both ends of the reinforcing bar are respectively fixed and connected to the structural plates through the fixing bolts. Thus, the connection between the two structural plates is made more firm through the reinforcing bar, and the connection firmness between the two structural plates is further strengthened through the fixing bolts, so as to meet the high requirements for firmness in the connection and installation of the microsatellite structural plates.

[0032] In the above structure and connection relationship, only one or two fixing bolts are needed at both ends of the reinforcing bar. Therefore, during the installation process of the structural plate, the number of installed fixing bolts is greatly reduced, significantly reducing the installation time and installation procedures.

[0033] Moreover, the above-mentioned structural plate system provided by the present invention is not only easy to install through mortise and tenon connections and does not require too many fixing bolts to be installed. Therefore, it is suitable for the installation method applicable to an automated production line.

[0034] In the embodiment of the present invention, in order to facilitate the installation of the reinforcing bar and the fixing bolt, corresponding reinforcing bar installation holes and fixing bolt installation holes can be provided on the structural plate. It should be noted that for some structural plates, reinforcing bars may need to be installed on all sides, while for some structural plates, only some of the sides may need to install reinforcing bars. Then, during actual use, the reinforcing bar installation holes can be opened on the corresponding sides as needed, and at the same time, the fixing bolt installation holes can be opened at the two ends where the fixing bolts need to be installed. For example, when six structural plates are connected to form a cuboid structure, generally, reinforcing bars need to be installed on the eight edges of the upper and lower surfaces of the cuboid. Then, on the four sides of the structural plates located on the upper and lower surfaces, both the reinforcing bar installation holes and the fixing bolt installation holes need to be opened. For the structural plates located on the four side surfaces, only the reinforcing bar installation holes and the fixing bolt installation holes need to be opened on the sides connected to the structural plates on the upper and lower surfaces.

[0035] In the embodiment of the present invention, the reinforcing bar can be embedded at the mortise and tenon connection of two structural plates. That is, the end of the reinforcing bar cannot be seen from the outside.

[0036] In the embodiment of the present invention, as Figure 4 shown, threads are provided at both ends of the reinforcing bar 2.

[0037] By providing threads at both ends of the reinforcing bar, during the installation process, it is convenient to use corresponding tools to install the reinforcing bar in an embedded manner. As an embodiment, for example, the corresponding tool can be a long round bar with threads processed at one end. The relationship between the long round bar and the reinforcing bar is similar to the relationship between a bolt and a nut. During use, the threads on the long round bar can cooperate with the threads on the reinforcing bar to work. The long round bar and the reinforcing bar can be tightened through the threads, and then the reinforcing bar can be placed at the preset installation position through this long round bar, aligning the bolt holes on the reinforcing bar with the bolt holes on the structural plate, and installing the fixing bolts. After the reinforcing bar is installed in place, the long round bar can be screwed out through the threads.

[0038] Among them, the threads can be provided at the end of the reinforcing bar, and fixing bolt installation holes are opened near the threads. After the reinforcing bar is installed, the reinforcing bar and two connecting plates are connected and fixed using fixing bolts.

[0039] In the present invention, two fixing bolt mounting holes can be provided at each end to further ensure the stability of the connection.

[0040] In an embodiment of the present invention, as Figure 5 shown, symmetric bosses 4 can be provided on the reinforcing bar 2.

[0041] Among them, the boss has a guiding function to ensure that the bolt holes of the reinforcing bar are in the same opening direction as those of the structural plate during installation. Other structures can also be provided on the reinforcing bar as long as they have a guiding function and do not affect the embedded installation of the reinforcing bar. For example, grooves can also be opened.

[0042] In an embodiment of the present invention, the protruding direction of the boss 4 is perpendicular to the direction of the hole for installing the fixing bolt 3.

[0043] Adopting the above structure makes the guiding function of the boss more intuitive and distinct, making it easier to confirm the direction of the bolt holes, further reducing the installation difficulty and accelerating the installation speed.

[0044] In an embodiment of the present invention, the reinforcing bar 2 can be provided with a hollow structure.

[0045] During the use of the reinforcing bar, the mortise and tenon connection structures between two adjacent structural plates are connected in series, making the connection between the two adjacent structural plates more firm. Therefore, setting the reinforcing bar as a hollow structure can not only meet the above use requirements, but also reduce the self-weight and material consumption of the reinforcing bar, which has a very favorable promoting effect on the production of satellites.

[0046] In an embodiment of the present invention, the system further includes a non-standard customized bolt 5 (see Figure 6 ), and the non-standard customized bolt 5 is installed at the mortise and tenon connection of the three mutually perpendicular connected structural plates 1 (see Figure 1 , 2 ).

[0047] The non-standard customized bolt is a non-standard bolt that can be customized according to the use requirements, and its size can be adjusted accordingly according to the requirements of other structural parts.

[0048] During the satellite production process, if a structure where three structural plates are mutually perpendicular and connected is required, non-standard customized bolts can be installed at the mortise and tenon connections of the three structural plates to more firmly connect the three mutually perpendicular connected structural plates. For example, when six structural plates are connected to form a cuboid structure, the structures at the four side edges of the cuboid structure (see Figure 1 , 2)That is, it is the mortise and tenon joint where three structural plates are perpendicularly connected to each other. The non-standard customized bolts can be installed at each side. During the installation process, the non-standard customized bolts penetrate from the upper structural plate to the lower structural plate, so as to use the non-standard customized bolts to connect the mortise and tenon structures of the mutually perpendicular structural plates on three sides. During the installation process, the non-standard customized bolts can be installed in the direction from top to bottom or in the direction from bottom to top.

[0049] Among them, the non-standard customized bolt 5 is arranged in a hollow structure.

[0050] During the use of the non-standard customized bolt, by connecting the mortise and tenon connection structures between three mutually perpendicular connected structural plates, the connection between the three mutually perpendicular connected structural plates becomes more firm. Therefore, setting the non-standard customized bolt in a hollow structure can not only meet the above use requirements, but also reduce the self-weight and material consumption of the non-standard customized bolt, which has a very favorable promoting effect on the production of satellites.

[0051] In the embodiment of the present invention, the reinforcing rod 2 can be installed along the X and Y directions, and the non-standard customized bolt 5 can be installed along the Z direction.

[0052] Adopting the above structure can enable the two or three mutually connected structural plates in different directions and positions to be strengthened and fixedly connected through the reinforcing rod or the non-standard customized bolt. For example, when using six structural plates to be mutually connected to form a cuboid structure, the reinforcing rods can be installed on the four upper edges and the four lower edges of the cuboid structure, and the non-standard customized bolts can be installed on the four side edges of the cuboid. And the two ends of the reinforcing rods installed on the upper and lower edges are indented inside the edges, so that the connection positions of the two edges can be used to install the non-standard customized bolts. (See Figure 1 、 2 )

[0053] In the embodiment of the present invention, six structural plates 1 are provided, eight reinforcing rods 2 are provided, thirty-two fixing bolts 3 are provided, and four non-standard customized bolts 5 are provided; the six structural plates 1 are mortise and tenon connected into a cuboid structure, the reinforcing rods 2 are embedded in the edges of the upper and lower surfaces of the cuboid, and both ends of each reinforcing rod 2 are respectively fixed by two fixing bolts 3, and the non-standard customized bolts 5 are installed through the four side edges of the cuboid.

[0054] The structural plate system provided by the embodiment of the present invention further includes a reinforcing structural plate, and mortise and tenon structures are arranged on each edge of the reinforcing structural plate, and the reinforcing structural plate is mortise and tenon connected with the structural plate 1.

[0055] Among them, the reinforcing structural plate is generally used for the reinforcement inside the satellite. The structure of the reinforcing structural plate is the same as that of the structural plate, and mortise and tenon structures are provided on each side. During use, the reinforcing structural plate can be mortise-and-tenon connected to the structural plate without using fixing bolts for connection and fixation.

[0056] In a specific embodiment of the present invention, the rapid assembly of the structural plate system of a certain microsatellite was completed according to the following process. Figure 7 Isometric view after assembly completion. Figure 8 Is the exploded view after assembly completion. As Figure 7 、 8 Shown, during the assembly process, six structural plates were used, namely ±X, ±Y, ±Z plates; eight reinforcing rods; four non-standard customized bolts and thirty-two fixing bolts. In order to increase the structural stiffness, a reinforcing structural plate (0Z plate) was used inside.

[0057] The specific assembly process may include the following steps:

[0058] Step 1, fix the +Y plate on the tooling, perform mortise-and-tenon connections between the +Z plate and the -Z plate and the +Y plate respectively, and then embed and install reinforcing rods on the connecting edges between the +Z plate and the +Y plate and between the -Z plate and the +Y plate for connection and fixation.

[0059] Step 2, directly perform mortise-and-tenon connection between the 0Z plate and the +Y plate, and then perform mortise-and-tenon connections between the +X plate and the -X plate and the +Z plate, -Z plate, 0Z plate, and +Y plate respectively, and embed and install reinforcing rods on the connecting edges between the +X plate and the +Y plate and between the -X plate and the +Y plate for connection and fixation.

[0060] Step 3, perform mortise-and-tenon connections between the -Y plate and the +X plate, -X plate, +Z plate, -Z plate, and 0Z plate respectively, and embed and install reinforcing rods on the connecting edges between the +Z plate and the -Y plate, between the -Z plate and the -Y plate, between the +X plate and the -Y plate, and between the -X plate and the -Y plate for connection and fixation.

[0061] Step 4, install non-standard customized bolts at the joints of the three mutually perpendicular connected structural plates for reinforcement again. For example, the -X plate, +Z plate, and -Y plate are mutually perpendicular and connected. Install non-standard customized bolts downward from the -Y plate at their joint to string together the mortise-and-tenon structures of the -X plate, +Z plate, and -Y plate for reinforcement.

[0062] Although the preferred embodiments of the present invention have been described, additional changes and modifications can be made to these embodiments by those skilled in the art once they learn the basic creative concept. Therefore, the appended claims are intended to be interpreted as including the preferred embodiments and all changes and modifications that fall within the scope of the present invention. Obviously, those skilled in the art can make various changes and variations to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalent technologies, the present invention is also intended to include these modifications and variations.
