Description

Technical Field

[0001] The present invention belongs to the technical field of satellite docking, and particularly relates to a high-adaptability point array type mother-satellite and daughter-satellite mounting interface structure. Background Art

[0002] In the aerospace field, the carrying of mother-satellites and daughter-satellites usually adopts a specified carrying mode, that is, the relationship between the daughter-satellite and the mother-satellite is one-to-one correspondence. The carrying object of the daughter-satellite has usually been demonstrated and confirmed in the mission plan stage, that is, the mother-satellite object carried by the daughter-satellite and the mounting interface have been determined. At present, the daughter-satellite does not have a wide range of adaptability to the carrying requirements of sudden tasks or diverse tasks. Specifically, the existing mounting interfaces have the following problems:

[0003] 1. For non-standardized mother-satellites, the existing carrying methods of mother-satellites and daughter-satellites are relatively rigid, adopting a systematic design of one-to-one adaptation, which has high requirements for the carrying environment of the mother-satellite, and the daughter-satellite cannot carry mother-satellites of other projects.

[0004] 2. The positions of the existing daughter-satellite mounting interfaces are usually fixed layouts based on aluminum honeycomb panel embedded parts, and the spatial positions cannot be adapted or the adaptation period is long, often leading to a large degree of layout change or scheme change.

[0005] 3. For the existing carrying tasks where the daughter-satellite needs to carry multiple different types of mother-satellites at the same time, there is a lack of highly general or adaptable mounting interfaces, resulting in difficulty for the daughter-satellite to quickly standardize and difficulty in spectral design.

[0006] 4. The existing mother-satellite and daughter-satellite carrying tasks often have the same task starting point for the daughter-satellite and the mother-satellite. In the case of sudden tasks, mother-satellites developed earlier than daughter-satellites or mother-satellites that do not give priority to the carrying of daughter-satellites, there is a lack of a mounting interface that can enable the daughter-satellite to quickly adapt to the docking surface environment of the mother-satellite. Summary of the Invention

[0007] The present invention proposes a high-adaptability point array type mother-satellite and daughter-satellite mounting interface structure, which solves the technical problems such as the existing daughter-satellite mounting interface having high requirements for the carrying environment of the mother-satellite, poor adaptability, and low generality.

[0008] The present invention can be realized through the following technical solutions:

[0009] A high-adaptability point array type mother-satellite and daughter-satellite mounting interface system includes an adapter panel provided on the daughter-satellite or the mother-satellite. A plurality of mounting holes are prefabricated on the adapter panel. These mounting holes are all used for installing separation mechanisms and are distributed on a plurality of concentric circles with the geometric center of the adapter panel as the center. The plurality of mounting holes on the same concentric circle are evenly spaced.

[0010] According to the interface positions on the mother star or the sub - star to be docked, first determine the installation hole positions on the adapter panel where the separation mechanism needs to be installed, install the separation mechanism at the corresponding positions, and then use the assembled adapter panel to achieve the docking of the mother - son stars;

[0011] Or according to the interface positions on the mother star or the sub - star to be docked, first determine the positions on the adapter panel where the separation mechanism needs to be installed, then directly drill holes at the corresponding positions on the adapter panel, install the separation mechanism, and finally use the assembled adapter panel to achieve the docking of the mother - son stars.

[0012] Furthermore, the adapter panel adopts a rectangular structure, the installation holes are set at the intersection positions of the concentric circles and the diagonal lines of the adapter panel, and the intervals between adjacent concentric circles are equal.

[0013] Furthermore, a travel switch is also installed at each installation hole position.

[0014] Furthermore, a load - bearing bracket is provided on the side of the adapter panel where the installation holes are oppositely arranged. The load - bearing bracket adopts a hollow design, and its main beam is set at the diagonal position of the adapter panel.

[0015] Furthermore, when docking, if the docking task has been determined in advance, first determine the installation hole positions on the adapter panel where the separation mechanism needs to be installed and the type of the separation mechanism according to the interface positions on the mother star or the sub - star to be docked, then install the separation mechanism and the travel switch at the corresponding positions, and finally use the assembled adapter panel to achieve the docking of the mother - son stars;

[0016] If the docking task has not been determined in advance, first determine the positions on the adapter panel where the separation mechanism needs to be installed and the type of the separation mechanism according to the interface positions on the mother star or the sub - star to be docked, then directly drill holes at the corresponding positions on the adapter panel, install the separation mechanism and the travel switch, and finally use the assembled adapter panel to achieve the docking of the mother - son stars.

[0017] Furthermore, if the sub - star or the mother star with the adapter panel can only be adapted to a single mother star or sub - star, only need to determine the installation hole positions on the adapter panel where the separation mechanism needs to be installed according to the interface positions on the mother star or the sub - star to be docked;

[0018] If the sub - star or the mother star with the adapter panel can be adapted to multiple mother stars or sub - stars, it is necessary to determine the installation hole positions on the adapter panel where the separation mechanism needs to be installed according to the interface positions on the mother star or the sub - star to be docked, and at the same time, the point - position layout corresponding to the determined installation hole positions meets the minimum combination requirements.

[0019] Furthermore, the number of interfaces on the sub - star and the mother star to be docked is the same, and the included angles of the diagonals of the formed quadrilateral are also correspondingly the same.

[0020] The beneficial technical effects of the present invention are as follows:

[0021] 1. The adapter design of the mounting interface of the present invention enables the sub-satellite to be quickly adjusted by selecting prefabricated mounting holes without major technical changes, and can meet the mounting requirements of different mother satellites without major layout adjustments of the sub-satellite.

[0022] 2. The multi-radius distributed hole design adopted by the present invention can maximize the consideration of the mounting requirements of different interface environments on the premise that the projection of the centroid of the sub-satellite on the interface is located at the center of the interface, realize the quick adjustment and change of the mounting interface in different mounting scenarios, and improve the flexibility and agility of the overall task.

[0023] 3. The adapter panel can be used as the structural panel or additional component of the sub-satellite at the same time. When the sub-satellite is in the form of a cube satellite, it can be used as the structural panel, and when the sub-satellite is in a special configuration, it can be used independently as an additional component, enabling it to match the forms of sub-satellites of various configurations.

[0024] 4. The present invention uses a high-strength aluminum alloy frame to make the adapter panel and conducts lightweight design. The universal mounting function is realized on the premise of minimizing the weight gain cost.

[0025] 5. The travel switch of the mounting interface of the present invention adopts the same mounting interface as the point separation mechanism, further improving the overall adaptability and flexibility. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] The following details the specific implementation manners of the present invention in conjunction with the accompanying drawings and preferred embodiments.

[0032] As Figure 1As shown in the figure, the present invention provides a high - adaptability point - array type mother - and - daughter star mounting interface structure, including an adapter panel 1 provided on the daughter star or the mother star. A plurality of mounting holes 11 are opened on the adapter panel 1. These mounting holes 11 are all used for mounting the separation mechanism 2 and are distributed on a plurality of concentric circles with the geometric center of the adapter panel 1 as the center of the circle. A plurality of mounting holes 11 on the same concentric circle are evenly spaced.

[0033] According to the interface positions on the mother star or daughter star to be docked, first determine the positions of the mounting holes on the adapter panel 1 where the separation mechanism 2 needs to be installed, install the separation mechanism 2 at the corresponding positions, and then, with the help of the assembled adapter panel 1, achieve the docking of the mother - and - daughter stars.

[0034] Or according to the interface positions on the mother star or daughter star to be docked, first determine the positions on the adapter panel 1 where the separation mechanism 2 needs to be installed, then directly drill holes at the corresponding positions on the adapter panel 1, install the separation mechanism 2, and finally, with the help of the assembled adapter panel 1, achieve the docking of the mother - and - daughter stars.

[0035] In this way, since a plurality of mounting holes 11 are reserved on the adapter panel 1, it is possible to determine which mounting hole positions on the adapter panel 1 need to be assembled with the separation mechanism 2 according to the interface positions of the mother star or daughter star to be docked, so as to achieve docking, thus realizing "one - panel - multiple - fittings", fully improving the adaptability rate of the adapter panel 1, increasing the flexibility of the adapter panel 1 for docking use, expanding the application range of the adapter panel 1 for docking use, and having good versatility. At the same time, since the adapter panel 1 is a dedicated docking panel, when the reserved hole positions cannot meet the docking requirements, holes can be directly drilled on the adapter panel 1 to achieve docking.

[0036] In addition, the formed mounting interface adopts a generalized adapter design. The daughter - star body is installed on the mounting interface through a fixed interface, which can ensure the technical solidification and stability of the daughter - star design to the greatest extent.

[0037] Through the integrated design of the structural function of the adapter panel 1, this mounting interface can be used as the structural panel of the daughter star. Without design changes, by quickly reconstructing and adjusting the layout of the separation mechanism 2, it can meet the adaptability to different docking - surface environments.

[0038] Specifically as follows:

[0039] The adapter panel 1 adopts an integrated design of structural function. The material is selected as high - strength aluminum alloy. It can be directly used as the structural panel of the daughter star to be connected with other structural plates of the daughter star, or can be installed on the daughter star as an independent additional component. Of course, the adapter panel 1 can also be installed on the mother star according to needs.

[0040] When the sub - satellite mission is determined, at this time, the sub - satellite only designs the system according to its own mission requirements. The configuration of the sub - satellite does not need to be restricted to a specific form, and only the installation interface of the adapter panel 1 needs to be retained. In particular, when the form of the sub - satellite is a CubeSat, the adapter panel 1 can be directly used as the structural panel of the satellite docking surface.

[0041] As Figure 2 shown, the adapter panel 1 can adopt a rectangular structure, and there are multiple mounting holes 11 reserved on it. A multi - radius distribution hole position design can be adopted. The positions of each hole are the intersection positions of concentric circles with the geometric center of the adapter panel as the center point and the diagonal of the adapter panel 1. The interval between two adjacent concentric circles is equal, and the specific value can be adjusted according to the actual size of the sub - satellite to cover most docking requirements.

[0042] Every four hole positions distributed on the same concentric circle are in a group, which can be used as a layout scheme for the separation mechanism 2 to be selected. And each hole position can be used to install the travel switch 3 at the same time. Also, the travel switch 3 can be installed at the geometric center position of the adapter panel to complete the detection of the interface position and even the docking state between the docked mother and sub - satellites. Each group of schemes can ensure that the projection of the satellite's centroid on the docking surface is located at the center of the separation mechanism 2, guaranteeing the mechanical symmetry of the sub - satellite's payload. At the same time, the travel switch 3 and the separation mechanism 2 adopt the same installation interface, so that the travel switch 3 and the separation mechanism 2 share the hole positions, making the whole more flexible.

[0043] The separation mechanism 3 can be selected specifically according to the docking requirements, such as a point - type separation mechanism, etc.

[0044] As Figure 3 shown, the back surface of the adapter panel 1, that is, the opposite surface of the mounting holes, is designed for weight reduction. There is a load - bearing bracket 12 set on it. The load - bearing bracket 12 adopts a hollow design, and its main beam is set at the diagonal position of the adapter panel, so that each preset group of mounting hole positions can ensure the system stiffness between the separation mechanism 2 and the sub - satellite, improving the payload stability of the sub - satellite.

[0045] When using the adapter panel 1 of the present invention for docking, if the docking task has been determined in advance, first determine the installation hole positions of the separation mechanism 2 and the type of the separation mechanism 3 that need to be installed on the adapter panel 1 according to the interface positions on the mother satellite or sub - satellite to be docked. Then install the separation mechanism 2 and the travel switch 3 at the corresponding positions, and then use the assembled adapter panel 1 to achieve the docking of the mother and sub - satellites;

[0046] If the docking task is not determined in advance, first determine the position on the transfer panel 1 where the separation mechanism 2 needs to be installed and the type of the separation mechanism 2 according to the interface positions on the mother star or the sub-star to be docked. Then directly drill holes at the corresponding positions on the transfer panel 1, and then install the separation mechanism 2 and the travel switch 3. Finally, with the assembled transfer panel 1, the docking of the mother star and the sub-star is achieved;

[0047] If the sub-star or the mother star with the transfer panel 1 can only be adapted to a single mother star or sub-star, only determine the installation hole positions of the separation mechanism 2 on the transfer panel 1 according to the interface positions on the mother star or the sub-star to be docked;

[0048] If the sub-star or the mother star with the transfer panel 1 can be adapted to multiple mother stars or sub-stars, it is necessary to determine the installation hole positions of the separation mechanism 2 on the transfer panel 1 according to the interface positions on the mother star or the sub-star to be docked, and at the same time, the point layout corresponding to the determined installation hole positions meets the minimum combination requirement, that is, the diagonal angles α of the polygons formed by the interface positions of each mother star and the sub-star interface positions, such as a quadrilateral, are correspondingly the same.

[0049] As Figure 4 shown, the specific process of setting the transfer panel on the sub-star is as follows:

[0050] 1. The sub-star task is determined. At this time, the sub-star only conducts system design according to its own task requirements. The configuration of the sub-star does not need to be restricted to a specific form, and only the installation interface of the transfer panel needs to be reserved;

[0051] 2. According to whether the mother star to be docked is within the combined launch task and the number of adaptable mother stars, it is divided into the following four situations to confirm the installation hole positions on the transfer panel for installing the separation mechanism:

[0052] ①. For a single mother star specified in the combined launch task plan, directly determine the installation hole positions on the sub-star transfer panel for installing the separation mechanism according to the coordinated interface positions with this mother star;

[0053] ②. For multiple mother stars specified in the combined launch task plan, jointly determine the minimum combination plan of the array installation holes of the separation mechanism on the transfer panel according to the coordinated interface positions with each type of mother star, that is, the diagonal angles α of the polygons formed by the interface positions of each mother star and the sub-star interface positions, such as a quadrilateral, are correspondingly the same;

[0054] ③. For a single mother star to be determined outside the combined launch task plan, according to the uncoordinated interface positions reserved on the mother star, at this time, the mother star only needs to have a unified separation mechanism model, quickly determine the installation points of the required separation mechanism on the transfer panel, and then directly drill holes;

[0055] ④. For multiple mother satellites to be determined outside the combined launch mission plan, according to the uncoordinated interface positions reserved for each type of mother satellite, at this time, the mother satellite only needs to have a unified point separation mechanism model. The interface positions of each mother satellite and the sub-satellite interface positions also need to ensure the same included angle α. Determine the minimum combination plan of the array installation hole positions of the required separation mechanism on the adapter panel, and then directly drill holes on the adapter panel.

[0056] 3. According to the installation hole positions confirmed in step 2 or the hole positions directly drilled on-site, install the separation mechanism and the travel switch on the adapter panel together, and then use the assembled adapter panel to achieve the docking of the mother and sub-satellites.

[0057] 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 foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
