[0029] The present invention will be further described below with reference to the embodiments.

[0030] This invention provides a modular drawer-type flat-panel satellite structure. The modular design allows for flexible expansion of functions and structure. The drawer-type structure eliminates the need for compartments, enabling efficient and rapid integration, assembly, and equipment replacement.

[0031] The modular drawer-type flat-panel satellite structure consists of n modules; each module is a flat-panel structure; the n modules are stacked vertically to form the overall flat-panel satellite structure; any module can be removed or installed; the modules are irregularly shaped; and n is a positive integer greater than or equal to 3.

[0032] In terms of overall design, the module consists of three parts: a shell 1, a plug-in plate 2, and an interface plate 3. The plug-in plate 2 is an irregularly shaped plate structure; the shell 1 is a hollow shell structure adapted to the shape of the plug-in plate 2; the shell 1 is placed horizontally, and an opening is provided on the side wall of the shell 1; the plug-in plate 2 is inserted into the shell 1 through the opening in the horizontal direction; the interface plate 3 is located at the opening of the shell 1; the interface plate 3 is connected to the plug-in plate 2; information transmission and power supply between the modules are realized through the plug-in plate 2.

[0033] The design varies slightly depending on the shape of the module.

[0034] The bottom of the inner wall of the outer shell 1 is provided with a guide rail, which allows the insert plate 2 to be inserted into the outer shell 1 along the guide rail; the inner cavity of the outer shell 1 is provided with a vibration damping and buffering structure to support and buffer the insert plate 2. An automatic locking device is provided on each of the two sides of the top of the inner cavity of the outer shell 1; after the insert plate 2 is fully inserted into the inner cavity of the outer shell 1, the positioning pin of the automatic locking device automatically falls down to position the insert plate 2.

[0035] A spring-loaded clamping device is provided at the rear of the inner cavity of the outer shell 1; when the insert plate 2 is not inserted, the spring-loaded clamping device is in a free state; after the insert plate 2 is inserted, the spring-loaded clamping device is in a clamped state; when it is necessary to remove the insert plate 2, external force is applied, the spring-loaded clamping device unlocks and provides a pop-out force, so that the insert plate 2 can quickly detach from the outer shell 1.

[0036] like Figure 1 As shown, the insert plate 2 is a semi-annular plate structure; the outer shell 1 is a semi-annular hollow shell adapted to the shape of the insert plate 2; after the insert plate 2 is inserted into the outer shell 1, two interface plates 3 are installed at the two openings of the outer shell 1.

[0037] like Figure 2 As shown, when the load-bearing bucket 4 is provided, after the insert plate 2 is inserted into the outer casing 1, the inner ring side wall of the outer casing 1 is sealed and a docking interface is provided; the outer casing 1 is horizontally installed on the side wall of the load-bearing bucket 4 through the docking interface.

[0038] For the transportation of traditional load-bearing barrel structures, the following methods can be adopted: Figure 2 The design is a ring. The ring can be connected to and separated from the load-bearing tank via a separation device on the inner side.

[0039] Outer Shell 1: The internal design incorporates guide rails to support the inner panel and provide shock absorption. The bottom of the outer shell features an automatic separation mechanism; the inner panel can be quickly removed by spring-loaded clamping and releasing. Automatic locking devices on both sides of the outer shell securely fasten and fix the inner panel.

[0040] Insert Board 2: Various platform and payload devices can be installed as needed. These devices connect to the interface board via the insert board, enabling power supply and signal transmission. The insert board can not only support internal equipment of the flat-panel satellite but also install and support external equipment.

[0041] Interface Board 3: The interface board supports various interfaces to achieve signal transmission and power supply, while also securing the inner board and outer shell. The interface board is designed with positioning guide rods to ensure accurate insertion of the plug-in board.

[0042] Insert the insert plate 2 into the outer casing 1 in the direction of the arrow. After insertion, the positioning pins in the automatic locking devices located on both sides inside the outer casing 1 will fall down and fix the insert plate 2. At the same time, there is a spring-loaded clamping device at the bottom of the outer casing 1. When the insert plate 2 is not inserted, it is in a free state, and when the insert plate 2 is inserted, it is in a clamped state. When removing the insert plate 2, external force can unlock the automatic locking device. Then, the clamping device at the bottom of the outer casing 1 will apply an outward spring force to the inside, and the insert plate 2 will pop out a certain distance, and then the insert plate 2 can be pulled out.

[0043] like Figure 3 As shown, the insert plate 2 is a semi-circular plate structure; the outer shell 1 is a semi-circular hollow shell adapted to the shape of the insert plate 2; the interface plate 3 is a vertically placed rectangular plate structure; after the insert plate 2 is inserted into the outer shell 1, the interface plate 3 is installed at the opening of the outer shell 1.

[0044] like Figures 1 to 3 This application presents a single-sided push-pull structure design.

[0045] The single-sided push-pull structure also supports expansion. If a single inner panel cannot meet the satellite's requirements, multiple of the above structures can be stacked to meet functional, performance, and capacity requirements. Only the interface board needs to be expanded to fix the multi-layered outer shell and inner panels, while also enabling information transmission and power supply between the inner panels.

[0046] The single-sided push-pull housing and interface board support various shapes, such as Figure 5 It can meet various launch space constraints and the mixed use of various types of satellites.

[0047] like Figure 4 As shown, the insert plate 2 is a circular plate structure; each outer shell 1 is a semi-circular hollow shell structure; the two outer shells 1 are joined together to form a circular hollow shell structure that conforms to the shape of the insert plate 2; two interface plates 3 are symmetrically arranged on the upper surface of the insert plate 2; two through holes are provided on the upper surface of the outer shell 1 at the positions corresponding to the two interface plates 3.

[0048] When the insert plate 2 is a circular plate structure, during assembly, first insert the insert plate 2 horizontally into the inner cavity of one of the outer shells 1; then, horizontally fit the other outer shell 1 onto the outer wall of the insert plate 2 from the other end.

[0049] Figure 4This invention relates to a double-sided push-pull structure design. Some structures cannot be achieved using a single-sided push-pull method and require a double-sided push-pull structure. Taking a circular double-sided push-pull structure as an example, the insert plate 2 is pushed into one of the outer shells 1 in the direction of the arrow, and then the other outer shell 1 is pushed into the other side of the insert plate 2. After insertion, the positioning pins in the automatic locking devices located on both sides inside the outer shell 1 will fall down to fix the insert plate 2. Simultaneously, there is a spring-loaded clamping device at the bottom of the outer shell 1. When the insert plate 2 is not inserted, it is in a free state; when the insert plate 2 is inserted, it is in a clamped state. When removing the insert plate 2, external force can unlock the automatic locking device. Then, the clamping device at the bottom of the outer shell 1 will apply an outward spring force to the insert plate 2, causing it to spring out a distance in the opposite direction of the arrow, after which the insert plate 2 can be pulled out.

[0050] The dual-sided push-pull structure also supports expansion. If a single insert 2 cannot meet the satellite requirements, multiple of the above structures can be stacked to meet the requirements in terms of function, performance, and capacity. This achieves the fixation of the multi-layer shell 1 and the insert 2, while also enabling information transmission and power supply between the insert 2.

[0051] The dual-sided push-pull housing and interface board support various shapes, such as Figure 6 As shown, the outer shell can be divided into two parts according to the dotted line in the figure, which can meet various launch space constraints and the mixed use of various types of satellites.

[0052] The design can adopt polygonal, arc-shaped or other configurations according to the characteristics of the vehicle to maximize the utilization efficiency of the vehicle space.

[0053] The present invention adopts a modular design that allows for flexible expansion of functions and structure. The drawer-type structure eliminates the need for compartments, enabling efficient and rapid integration, assembly, and equipment replacement.

[0054] This invention enables flexible expansion of the functions and structure of flat-panel satellites, improving assembly and replacement efficiency while maximizing the utilization of launch space. This invention stacks multiple modules to meet the requirements in terms of function, performance and capacity, and can meet various launch space constraints and the mixed use of various types of satellites.

Any person skilled in the art can make possible changes and modifications to the technical solutions of the present invention by utilizing the methods and techniques disclosed above without departing from the spirit and scope of the present invention.
