[0037] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be described clearly and completely in conjunction with the drawings in the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0038] The following describes an on-orbit microbial cultivation experiment payload chassis provided by the present invention with reference to the accompanying drawings.

[0039] like Figures 1 to 7 As shown, the on-orbit microbial cultivation experiment payload chassis according to the first aspect of the embodiment of the utility model includes a payload box body 1, a control device, a test device 4 and a camera 3.

[0040] The payload box 1 is composed of several detachable box panels, and a box space is formed inside the payload box 1. An installation interlayer 2 spanning the box space is also installed inside the payload box 1, and the installation interlayer 2 divides the box space into an installation cavity 17 and a culture cavity 18. In this way, the design of the box allows for rapid assembly and disassembly in a space station or other spacecraft, which is convenient for astronauts to operate and maintain.

[0041] The control device is installed in the interlayer cavity inside the installation interlayer 2, the camera 3 passes through the installation interlayer 2, the body of the camera 3 is located in the installation cavity 17 and its camera head is located in the culture cavity 18; the test device 4 is installed in the culture cavity 18 and is arranged opposite to the camera head.

[0042] It can be understood that the mounting interlayer 2 has a structural form with strong anti-bending ability. The utility model makes the control device the main anti-bending component of the equipment by installing the control device into the mounting interlayer 2 in the middle position of the chassis, thereby greatly improving the anti-mechanical performance of the equipment. By installing the control device in the mounting interlayer 2 with strong anti-bending ability, the anti-mechanical performance of the entire equipment is greatly improved. Furthermore, the structural integrity of the mounting interlayer 2 provides an additional layer of protection for the control device, ensuring that the control device can work normally even under extreme conditions, reducing the risk of failure, and ensuring the accuracy of experimental data and the continuity of the experimental process. In summary, the design of the above-mentioned mounting interlayer 2 and control device enables the equipment to better adapt to the complex and changeable mechanical environment of outer space, such as vibration and impact during the launch process, and various mechanical loads that may be encountered during in-orbit operation.

[0043] In addition, for the camera 3 and the test device 4: on the one hand, the camera 3 is an important component for monitoring and recording the experimental process, and it passes through the installation interlayer 2, so that the body of the camera 3 is located in the installation cavity 17, and the camera head is located in the culture cavity 18. Such a layout allows the camera head to directly observe the microbial culture conditions in the culture cavity 18, and the placement of the camera 3 body in the installation cavity 17 ensures its safety and stability.

[0044] On the other hand, the test device 4 is a specific device for conducting microbial culture experiments, including culture medium, experimental samples, etc. It is installed in the culture chamber 18 and arranged opposite to the camera, so that the camera can clearly capture the growth of microorganisms in the test device 4.

[0045] In related technologies, on-orbit microbial culture experimental equipment usually needs to be installed and operated in the cabinet of the space station. These devices must be able to withstand various mechanical loads encountered during launch and on-orbit operation, such as vibration, shock, and temperature changes. Cameras are key components used to observe and record the growth of microorganisms, but their mechanical resistance is usually weak and easily damaged during launch.

[0046] Traditional on-orbit experimental equipment may not have sufficient bending resistance and cannot withstand strong mechanical loads during launch and on-orbit operation, which can easily lead to equipment damage or experimental failure. The design of the equipment may not fully consider mechanical properties and operational convenience, resulting in complex on-orbit operations and increasing the workload and risks of astronauts. And due to space and resource constraints, traditional on-orbit experimental equipment may not provide sufficient flexibility and scalability, limiting the types and scale of experiments.

[0047] Therefore, in order to solve the defects existing in the above-mentioned related technologies, the utility model provides an on-orbit microbial culture experiment payload chassis, which has at least the following advantages compared with the related technologies:

[0048] (1) Enhanced anti-bending capability: Through the specially designed mounting interlayer 2, the utility model significantly improves the anti-bending capability of the device, enabling it to withstand various mechanical loads during launch and on-orbit operation, reducing the risk of device damage.

[0049] (2) Optimized structural layout: The interlayer 2 is installed to effectively divide the box space, so that the control device is located in the middle of the chassis. Such a layout helps to stabilize the center of gravity of the equipment, improve the overall mechanical properties and operational safety.

[0050] (3) Protective monitoring device: By arranging the camera in the culture chamber 18 and using a control device with a middle opening, the utility model provides sufficient protection for the camera 3 to ensure that it can work stably in harsh environments.

[0051] (4) Convenient for on-orbit operation: The detachable design of the chassis enables astronauts to easily update, debug and change samples on-orbit, thus improving the flexibility and efficiency of the experiment.

[0052] (5) Overall improvement in mechanical resistance: The control device, as the main anti-bending component, combined with other structural components, greatly improves the mechanical resistance of the entire equipment, making it more adaptable to the complex environment of outer space.

[0053] like Figure 4 and Figure 5 As shown, according to some embodiments of the utility model, the control device includes a first circuit board 51 and a second circuit board 52, the installation interlayer 2 includes a first interlayer cover 21, a interlayer main frame 22 and a second interlayer cover 23, the first circuit board 51 is installed in a first interlayer cavity formed between the first interlayer cover 21 and the interlayer main frame 22, and the second circuit board 52 is installed in a second interlayer cavity formed between the interlayer main frame 22 and the second interlayer cover 23.

[0054] In this embodiment, the control device implements an apparatus-based design. Specifically, the control device is composed of two independent circuit boards, each of which is responsible for different control functions. This apparatus-based design makes the system more flexible and convenient for optimization for specific tasks, and also facilitates fault diagnosis and maintenance. If a circuit board has a problem, it can be replaced separately without affecting the entire system, thereby improving the reliability and maintainability of the system.

[0055] The first interlayer cover 21, the interlayer main frame 22 and the second interlayer cover 23 together constitute a structure for mounting the interlayer 2. The interlayer main frame 22 serves as a core support structure to provide strength and rigidity, while the first interlayer cover 21 and the second interlayer cover 23 are respectively combined with the main frame to form two independent cavities for mounting circuit boards.

[0056] The first circuit board 51 is installed in the cavity formed between the first sandwich cover 21 and the sandwich main frame 22, which provides protection for the circuit board, and because it is located on one side of the sandwich structure, it can effectively utilize the space while maintaining the cooling and ventilation of the circuit board; the second circuit board 52 is installed in the cavity formed between the sandwich main frame 22 and the second sandwich cover 23. Similar to the first circuit board 51, the second circuit board 52 is also placed in a protective environment while maintaining good heat dissipation performance.

[0057] It can be understood that the sandwich structure of the present invention has the following advantages: (1) Bending resistance: The design of the sandwich structure enhances the bending resistance of the entire device, especially when facing mechanical loads during launch and on-orbit operation. The strength and rigidity of the sandwich main frame 22, as the main load-bearing structure, are crucial to protecting the internal circuit boards. (2) Space optimization: By installing the circuit boards in the sandwich structure, the present invention optimizes the internal space layout of the equipment. This layout not only improves space utilization, but also helps to reduce the overall volume of the equipment, leaving more space for other experimental components. (3) Maintenance and heat dissipation: The design of the sandwich structure takes into account the maintenance and heat dissipation needs of the circuit boards. The circuit boards are easy to access for routine inspection, maintenance or replacement. At the same time, the sandwich structure can be designed in a way that is conducive to air circulation, helping to dissipate the heat generated by the circuit boards and prevent overheating.

[0058] like Figure 4 and Figure 5 As shown, in some specific embodiments of the present invention, the first circuit board 51 , the second circuit board 52 , the first interlayer cover 21 and the second interlayer cover 23 are all provided with a plurality of through holes 53 , and the interlayer main frame 22 is provided with a plurality of fixing wells 221 .

[0059] One side of the fixing well 221 passes through the through hole 53 on the first circuit board 51 and the first interlayer cover 21 in sequence, and the other side of the fixing well 221 passes through the through hole 53 on the second circuit board 52 and the second interlayer cover 23 in sequence, and the camera 3 passes through the through hole 53 and the fixing well 221.

[0060] In this embodiment, the plurality of fixing wells 221 on the sandwich main frame 22 are specially designed to pass through the through holes 53 of the circuit board and the sandwich cover to achieve stable installation and positioning of the camera 3. Correspondingly, the first circuit board 51, the second circuit board 52, the first sandwich cover 21 and the second sandwich cover 23 are all provided with through holes 53, which are used to allow the fixing wells 221 of the sandwich main frame 2 to be connected with other components, and also provide a channel for the camera 3 to pass through.

[0061] The installation path of the camera 3 is realized by sequentially passing through the through hole 53 and the fixing well 221. This means that the camera 3 first passes through the through hole 53 on the first circuit board 51 and the first interlayer cover 21, passes through the fixing well 221, and then passes through the through hole 53 on the second circuit board 52 and the second interlayer cover 23, and finally reaches its predetermined position.

[0062] Thus, through this design, the installation of the camera 3 becomes more stable and accurate. The fixing well 221 ensures the alignment and positioning of the camera 3 when passing through the sandwich structure, reducing image deviation or distortion caused by improper installation.

[0063] Furthermore, the through hole 53 and the fixing well 221 in the design not only provide convenience for the installation of the camera 3, but also provide convenience for future maintenance and access. If the camera 3 needs to be maintained or replaced, it can be operated through these holes and wells without having to disassemble the entire control device.

[0064] Most importantly, this design allows the camera 3 to pass through the control device without taking up additional space, thereby achieving a compact layout of the equipment. This is particularly important for space-constrained environments, such as the interior of a space station. In addition, despite the opening of the through hole 53, the structural integrity and strength of the sandwich main frame 22 will not be affected. By properly designing the size and location of the hole and using appropriate reinforcement measures, it can be ensured that the mechanical properties of the sandwich main frame 22 are not affected.

[0065] like Figure 2 and 3 As shown, according to some embodiments of the present invention, a side wall of the second interlayer cover 23 facing the culture chamber 18 forms an installation reference surface 231, the test device 4 is arranged opposite to the installation reference surface 231, and the camera is fixed on the installation reference surface 231 and faces the test device 4.

[0066] In this embodiment, one side wall of the second interlayer cover 23 is specially designed as a mounting reference surface 231. This mounting reference surface 231 is a key reference surface for ensuring accurate mounting of the camera and other components. Its design takes into account the alignment and distance with the culture chamber 18 so that the camera can clearly observe the test device 4.

[0067] The test device 4 is arranged in the culture chamber 18 and is opposite to the mounting reference surface 231 of the second interlayer cover 23. Such a layout ensures that the test device 4 is within the field of view of the camera, making it easy for the camera to monitor and record the test process.

[0068] The camera is fixed on the mounting reference surface 231 and faces the test device 4. This design allows the camera to be stably aligned with the test device 4, and the correct shooting direction and focal length can be maintained regardless of whether it is during the launch process or when it is running on orbit.

[0069] Thus, the advantages of the above design include the following: precise alignment: by fixing the camera on the mounting reference surface 231, the alignment between the camera and the test device 4 can be ensured to be accurate, thereby obtaining high-quality image data; stable monitoring: the stable installation of the camera helps to reduce image blur caused by vibration or impact, and ensure the continuity and reliability of experimental monitoring; convenient operation: this layout provides astronauts with a convenient operating interface, making it easier to maintain and adjust the camera on orbit.

[0070] like Figure 5 As shown, in some specific embodiments of the present invention, the mounting reference surface 231 is further provided with a connection hole 232 connected to the first interlayer cavity and the second interlayer cavity respectively, and an electrical connector 61 is installed in the connection hole 232, and the electrical connector 61 is connected to the second circuit board 52. A circuit board connector 70 for connection is also provided between the first circuit board 51 and the second circuit board 52.

[0071] In this embodiment, the function of the connection hole 232 on the mounting reference surface 231 is to provide a channel for electrical connection between circuit boards. The connection hole 232 passes through the mounting reference surface 231, thereby allowing the electrical connector 61 to pass through the first interlayer cavity and the second interlayer cavity and connect to the corresponding circuit board.

[0072] It can be understood that the electrical connector 61 and the circuit board connector 70 are both electrical devices, wherein the electrical connector 61 is used to connect the second circuit board 52 and output to the outside, and the circuit board connector 70 is used to connect the first circuit board 51 and the second circuit board 52, so as to achieve efficient data transmission and power supply between the two circuit boards. Through the electrical connector 61 and the circuit board connector 70, the circuit board can easily output external signals and transmit signals between the two circuit boards, which also facilitates the maintenance and replacement of the circuit boards.

[0073] like Figure 5As shown, in some specific embodiments of the present invention, a fill light window 233 connected to the second interlayer cavity is further provided on the mounting reference surface 231 , and a fill light device 62 is installed in the fill light window 233 , and the fill light device 62 is connected to the second circuit board 52 .

[0074] In this embodiment, one or more light-filling windows 233 are provided on the mounting reference surface 231, and these windows are designed to be connected to the second interlayer cavity. The function of the light-filling windows 233 is to provide a channel for the light-filling device 62, so that light can be smoothly transmitted from the second interlayer cavity to the culture cavity 18.

[0075] A fill light device 62 is installed inside the fill light window 233. The fill light device 62 generally includes an LED lamp or other types of lighting elements, which are used to provide necessary illumination to support the growth of microorganisms and experimental observation in the culture chamber 18. The design of the fill light device 62 should take into account factors such as light intensity, color temperature and energy consumption to ensure the effectiveness of the experiment and the energy efficiency of the equipment.

[0076] The fill light device 62 is connected to the second circuit board 52. This connection ensures that the fill light device 62 can obtain the required power from the circuit board and can be managed and adjusted by the control device. Through the circuit board, the fill light device 62 can be precisely controlled, such as adjusting the brightness, on / off time, etc., to meet different experimental needs.

[0077] like Figure 2 As shown, according to some embodiments of the present invention, the load box includes a front side panel 11 , a rear side panel 12 , a left side panel 13 , a right side panel 14 , a top panel 15 and a bottom panel 16 .

[0078] The top plate 15 includes a fixed top cover 151 and a movable top cover 152. The fixed top cover 151 is fixedly mounted on the edges of the front side plate 11, the rear side plate 12 and the left side plate 13 and is arranged opposite to the installation cavity 17. The movable top cover 152 can be movably mounted on the edges of the front side plate 11, the rear side plate 12 and the right side plate 14 and is arranged opposite to the culture cavity 18 to open or close the culture cavity 18.

[0079] In this embodiment, the front side plate 11, the rear side plate 12, the left side plate 13, the right side plate 14, the top plate 15 and the bottom plate 16 constitute the main structure of the load box, providing a closed and protected space for the equipment. Together, they form a box structure to ensure the safety and stability of the internal components of the equipment.

[0080] The top plate 15 consists of a fixed top cover 151 and a movable top cover 152, which together constitute the top structure of the payload chassis. The fixed top cover 151 is fixedly mounted on the edges of the front side panel 11, the rear side panel 12 and the left side panel 13, and is arranged opposite to the installation cavity 17. The design of the fixed top cover 151 ensures the stability and safety of the installation cavity 17, and ensures the fixation and protection of key components such as the control device. The movable top cover 152 can be movably mounted on the edges of the front side panel 11, the rear side panel 12 and the right side panel 14, and is arranged opposite to the culture cavity 18. The design of the movable top cover 152 allows astronauts to open or close the culture cavity 18 as needed to conduct experimental operations, maintenance or replacement of internal components.

[0081] Thus, on the one hand, the design of the fixed top cover 151 and the movable top cover 152 provides additional protection for sensitive components inside the payload chassis to prevent damage in harsh environments, and on the other hand, the design of the movable top cover 152 provides a convenient operating interface for astronauts, making it easier and faster to operate the test device 4 in the culture chamber 18. That is, the structural design of the fixed top cover 151 and the movable top cover 152 ensures the stability of the equipment during transportation and launch, while allowing quick access to the internal space when needed.

[0082] like Figure 1 and Figure 6 As shown, in some embodiments of the present invention, two integrally formed sliding guide rails 63 are respectively provided on the outer wall surface of the left side plate 13 and the outer wall surface of the right side plate 14, and the sliding guide rails 63 extend in the front-to-back direction, and a guide rail joint 64 is formed at one end of the sliding guide rail 63 adjacent to the rear side plate 12.

[0083] Thus, the integrally formed sliding rail 63 provides higher structural stability and durability, reducing the risk of failure during the use of the equipment. The design of the sliding rail 63 allows the movable top cover 152 or other components to slide and position smoothly, making it easier for astronauts to operate and maintain.

[0084] In addition, the two guide rail joints 64 arranged on the rear side plate 12 ensure a relatively high-precision positional relationship. This design allows the device to be quickly and stably connected to other components with high precision, providing flexible docking and adjustment capabilities.

[0085] like Figure 2 , Figure 6 and Figure 7 As shown, in some embodiments of the present invention, air outlet holes 65 are provided on the left side panel 13 and the right side panel 14, and air inlet holes 66 are provided on the rear side panel 12. The air inlet holes 66 and the air outlet holes 65 are both connected to the box space.

[0086] In this embodiment, the air outlet 65 is used to carry the heat generated inside the device out of the chassis through airflow, helping to maintain the normal operating temperature of the device. The air inlet 66 is used to introduce cold air into the device.

[0087] The air inlet 66 and the air outlet 65 are both connected to the box space, forming a complete air flow channel. Such a design helps to form effective air convection and ensure temperature control and thermal management inside the device.

[0088] In this way, by properly arranging the air inlet holes 66 and the air outlet holes 65, the heat inside the device can be effectively discharged, while fresh cold air is introduced, thereby maintaining the normal operating temperature of the device.

[0089] In addition, properly designed vents can reduce fan noise and vibration caused by fan operation, which is especially important for on-orbit equipment because they need to operate stably in a microgravity environment.

[0090] like Figure 1 and Figure 7 As shown, in some embodiments of the present invention, a plurality of handles 67 are provided on the front side plate 11, and an interface hole 68 is also provided on the rear side plate 12, and an interface assembly 69 is fixedly installed in the interface hole 68. The interface assembly 69 is equipped with an electrical connection line and an electrical connector.

[0091] In this way, the design of handle 67 allows astronauts to operate the equipment more conveniently and to easily move the equipment whether it is being installed, maintained or replaced.

[0092] The design of the interface hole 68 helps maintain the stability of the electrical connection and the convenience of installation and maintenance, ensuring that the normal operation of the device will not be affected by connection problems. In addition, the location and design of the interface hole 68 can optimize the layout of the wires, making the wires neater and more orderly, and convenient for maintenance and inspection.

[0093] According to some embodiments of the present invention, the number of test devices 4 is not limited to one group, and similarly, the number of electrical connectors 61 and cameras 3 is more than one group. That is, the number of test devices 4 can be two or more groups, the number of electrical connectors 61 and cameras 3 can also be two or more groups, and the number of test devices 4, electrical connectors 61 and cameras 3 are equal and their positions correspond.

[0094] like Figure 3 As shown, in a specific embodiment, there are three groups of test device 4, electrical connectors 61 and cameras 3. Each group of electrical connectors 61 includes two separate electrical connectors 61.

[0095] The test device 4 is used for loading microbial samples and is a microbial culture experimental functional area. It supports astronauts to disassemble and install on orbit, and is mainly composed of a test device 4 shell, a culture unit, and a test device 4 electrical connector 61. The test device 4 includes a first test device 41, a second test device 42, and a third test device 43 arranged in sequence along the length direction of the installation interlayer 2, and three groups of electrical connectors 61 are also arranged in sequence along the length direction of the installation interlayer 2 and correspond to the three groups of test devices 4 respectively.

[0096] The first test device 41 is connected to two electrical connectors 61 in the same group. The first test device 41 includes 16 independent culture units. The independent culture units can be individually temperature-controlled by a control device, and the temperature control range is 25°C-43°C with an accuracy of ±1°C. The independent culture units can also be individually injected with liquid by a control device, and the liquid injection amount range is adjustable from 0.5mL to 3.0mL, and time-sharing injection is supported. The independent culture units provide the nutrient supply, temperature control and humidity conditions required for the growth of microorganisms through the control of the control device, and perform fluid replenishment according to the experimental needs to realize dynamic control of the process of microbial on-orbit experiments.

[0097] The second test device 42 is connected to two electrical connectors 61 in the same group. The second test device 42 includes two main parts, one of which is composed of three separately set culture units with larger size specifications, and the other part is composed of eight independent culture units with smaller size specifications. Each culture unit can be individually temperature controlled by the control device, with a temperature control range of 25-43°C and an accuracy of ±1°C. The nutrient supply and temperature control of each culture unit in the second test device 42 are similar to those of the first test device 41, and will not be repeated here.

[0098] The third test device 43 is connected to two electrical connectors 61 which are in the same group. The first test device 41 includes 16 independent culture units and has a structure basically the same as that of the second test device 42. The nutrient supply and temperature control of each culture unit in the third test device 43 are also similar to those of the first test device 41. Therefore, the present invention will not elaborate on the structure and function of the third test device 43.

[0099] like Figure 4 and Figure 5 As shown, the monitoring device in the utility model is mainly composed of a first camera 31, a second camera 32 and a third camera 33 which are arranged in sequence along the length direction of the installation interlayer 2. The camera head of the first camera 31 is arranged opposite to the first test device 41, the camera head of the second camera 32 is arranged opposite to the second test device 42, and the camera head of the third camera 33 is arranged opposite to the third test device 43.

[0100] The first camera 31 is controlled by the control device to perform static imaging and dynamic imaging of the first test device 41. The static imaging resolution is 2464×2056, and the dynamic imaging frame rate is 1fps. At the same time, the dynamic image data can be compressed, and the compression ratio is 16: 1. The lens focal length of the first camera 31 is 5mm, and the shooting object distance does not exceed 100mm, which can cover the whole picture of the first test device 41.

[0101] The second camera 32 performs static imaging and dynamic imaging on the second test device 42 through the control device, and the third camera 33 performs static imaging and dynamic imaging on the third test device 43 through the control device. The configuration of the second camera 32 and the third camera 33 is the same as that of the first camera 31, which will not be repeated here.

[0102] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein.
