Description

Technical Field

[0001] This invention relates to the technical field of online cabinets, specifically to an on-rail cantilever replaceable camera bracket and an online cabinet operation box for online cabinets. Background Technology

[0002] With the development of manned spaceflight technology, establishing long-term human habitation and working environments in outer space has become a central focus of human space exploration. Logistics support for the International Space Station is extremely expensive and difficult compared to any previous human exploration activity. The logistical challenges of establishing bases on the Moon and Mars in the future will be even more severe, especially in responding to emergencies, where delays in ground support could result in incalculable losses. Therefore, considering the initiative of astronauts, providing them with a range of tools and technical support to enhance the facilities' autonomous maintenance and support capabilities is a crucial measure to solve logistical support problems.

[0003] The online maintenance and assembly control cabinet (hereinafter referred to as the "online cabinet") is a scientific and technological experimental platform planned for space station application systems. It primarily provides a workspace for space station payloads to conduct on-orbit fault diagnosis, relay-level maintenance, and manual or mechanical operations. The online cabinet can utilize the intravehicular space environment provided by the manned space station, as well as the astronauts' on-orbit operation, maintenance, and replacement capabilities, while also addressing external constraints related to mechanical, electrical, thermal, information, and telemetry resources, to conduct on-orbit maintenance, assembly, and experimental research.

[0004] The camera assembly belongs to the scene observation camera of the online maintenance operation support unit (hereinafter referred to as "operation box"). Due to the limited space inside the box, it is also necessary to consider not interfering with the movement space of the internal robotic arm and not letting the internal lighting affect the camera imaging. Therefore, the number of cameras that can be installed in the operation box is limited. In order to ensure that the camera field of view can cover all operating areas inside the operation box while installing as few cameras as possible, the camera assembly must be small enough to occupy little space, and the camera must be replaceable on the track. The design of the camera bracket assembly needs to consider multiple design and usage factors at the same time. Summary of the Invention

[0005] To address the challenges of camera installation in complex environments within an operating cabinet, the difficulty of cantilever structures resisting launch overload, and the inability to replace cameras on track, this invention provides an on-track cantilever replaceable camera bracket and an operating cabinet operating box for use in online cabinets, ensuring the rapid assembly and disassembly of camera components and their pressure resistance requirements.

[0006] The technical solution of the present invention to solve the above-mentioned technical problems is as follows: an on-rail cantilever replaceable camera bracket for online cabinets, including a camera support and a camera bracket, the camera bracket including a first camera bracket and a second camera bracket, the first camera bracket and the second camera bracket being interlocked to form a cylindrical structure with openings at both ends, one end opening of the cylindrical structure being used to clamp a camera assembly, and the other end opening of the cylindrical structure having a support mounting surface; an angled box mounting surface and a camera bracket mounting surface are formed on the outer wall of the camera support, and the cylindrical structure is assembled on the camera bracket mounting surface through the support mounting surface.

[0007] The beneficial effects of the present invention are as follows: The online cabinet of the present invention uses an on-rail cantilever replaceable camera bracket. By setting a first camera bracket and a second camera bracket, the camera component can be wrapped and placed between the two camera brackets, so that the camera component is clamped in the camera bracket, which improves the stability of the overall cantilever part of the camera component; by setting a camera support and setting the box mounting surface and camera bracket mounting surface arranged at an angle, structural support can be provided for the camera bracket, and the on-rail replacement requirements are also taken into account, meeting the ergonomic requirements.

[0008] Based on the above technical solution, the present invention can be further improved as follows.

[0009] Furthermore, the camera support has a cable channel, a first cable through hole is provided at the camera bracket mounting surface of the camera support, a cable assembly surface is also formed on the outer side wall of the camera support, and a second cable through hole is provided at the cable assembly surface. Both the first cable through hole and the second cable through hole are connected to the cable channel.

[0010] Furthermore, the camera support has a closed structure on all sidewalls except for the first cable through hole and the second cable through hole.

[0011] The beneficial effect of adopting the above-mentioned further solutions is that it can improve the overall electromagnetic compatibility.

[0012] Furthermore, the cable mounting surface is arranged perpendicular to the housing mounting surface, the angle between the camera bracket mounting surface and the cable mounting surface is an acute angle, and the clamping angle between the camera bracket mounting surface and the housing mounting surface is an acute angle.

[0013] Furthermore, the camera bracket mounting surface is provided with three first mounting holes, two of which are located on the upper side of the camera bracket mounting surface and one of which is located on the lower side of the camera bracket mounting surface; the cylindrical structure support mounting surface is provided with three second mounting holes, which are arranged one-to-one with the three first mounting holes and connected and fixed by connectors.

[0014] The advantages of adopting the above-mentioned further solution are: by setting three first mounting holes and three second mounting holes, the camera assembly is prevented from being reversed during on-orbit replacement, which would affect the imaging effect; and when the hand space and field of view at the bottom of the camera assembly are limited, a first mounting hole is set on the underside of the camera bracket mounting surface to facilitate disassembly and assembly.

[0015] Furthermore, the first camera bracket is a C-shaped cylindrical structure, and the second camera bracket is a plate-shaped structure. The open side of the C-shaped cylindrical structure of the first camera bracket is detachably connected to the peripheral edge of the second camera bracket through a connector. All three second mounting holes are provided on the support mounting surface of the first camera bracket.

[0016] The advantage of adopting the above-mentioned further solution is that all camera components can be mounted and fixed on the first camera bracket, which facilitates installation, replacement and other operations.

[0017] Furthermore, one end of the cylindrical structure has a circular hole structure adapted to the camera assembly, and the other end of the cylindrical structure has a square hole structure adapted to the camera bracket mounting surface of the camera mount.

[0018] Furthermore, the mounting surface of the housing is a flat surface or an L-shaped surface; the thickness of the camera bracket and the camera support is 4-7mm respectively.

[0019] The advantage of adopting the above-mentioned further solutions is that different mounting surfaces of the enclosure can be used according to the requirements of the field of view inside the control box.

[0020] Furthermore, the first camera bracket and the second camera bracket are connected by a stop groove structure; the support mounting surface of the camera bracket and the camera bracket mounting surface on the camera bracket are connected by a stop groove structure; the first camera bracket or the second camera bracket is also provided with a camera mounting hole for connecting camera components.

[0021] The beneficial effect of adopting the above-mentioned further solution is that the use of the stop groove structure further improves the overall electromagnetic compatibility.

[0022] An online cabinet operation box includes a box body and an on-rail cantilever replaceable camera bracket for the online cabinet. The on-rail cantilever replaceable camera bracket for the online cabinet is provided at the top of each of the two opposite side walls of the box body at diagonal positions.

[0023] The beneficial effects of the present invention are as follows: The online cabinet operation box of the present invention reduces the volume occupied by the camera component on the camera bracket by setting a camera bracket at the top of each of the two opposite side walls of the box, thereby reducing the volume occupied by the camera component and avoiding interference between the camera component and the linear guide rail inside the operation box. At the same time, it avoids the brightness of the light strip from affecting the imaging effect of the camera. Attached Figure Description

[0032] The principles and features of the present invention are described below with reference to the accompanying drawings. The examples given are only for explaining the present invention and are not intended to limit the scope of the present invention.

[0033] like Figures 1-4 As shown in the figure, an online cabinet-type cantilever replaceable camera bracket in this embodiment includes a camera support 900 and a camera bracket. The camera bracket includes a first camera bracket 901 and a second camera bracket 902. The first camera bracket 901 and the second camera bracket 902 are interlocked to form a cylindrical structure with openings at both ends. One end of the cylindrical structure is used to hold a camera assembly, and the other end of the cylindrical structure has a support mounting surface 903. An angled box mounting surface 904 and a camera bracket mounting surface 905 are formed on the outer wall of the camera support 900. The cylindrical structure is assembled onto the camera bracket mounting surface 905 through the support mounting surface 903.

[0034] Among them, such as Figure 2 and Figure 4 As shown, the inner sidewalls of the first camera bracket 901 and the second camera bracket 902 in this embodiment are also provided with a plurality of step structures 912, which are used to adapt to the step structures on the outer sidewall of the camera assembly, and can tightly clamp the camera assembly between the first camera bracket 901 and the second camera bracket 902.

[0035] In this embodiment, the online cabinet uses an on-rail cantilever replaceable camera bracket. By setting a first camera bracket and a second camera bracket, the camera component can be wrapped and placed between the two camera brackets, so that the camera component is clamped in the camera bracket, which improves the stability of the overall cantilever part of the camera component. By setting a camera support and setting the box mounting surface and camera bracket mounting surface arranged at an angle, structural support can be provided for the camera bracket. It also takes into account the on-rail replacement requirements and meets the ergonomic requirements.

[0036] like Figure 1 and Figure 3 As shown, the camera support 900 in this embodiment has a cable channel. A first cable through hole 906 is provided at the camera bracket mounting surface 905 of the camera support 900. A cable assembly surface is also formed on the outer side wall of the camera support 900. A second cable through hole 907 is provided at the cable assembly surface. Both the first cable through hole 906 and the second cable through hole 907 are connected to the cable channel.

[0037] like Figures 1-4 As shown, in this embodiment, the camera support 900 has a closed structure on all sidewalls except for the first cable through hole 906 and the second cable through hole 907, which can improve the overall electromagnetic compatibility.

[0038] like Figures 1-4 As shown, in this embodiment, the cable assembly surface is arranged perpendicular to the housing mounting surface 904, the angle between the camera bracket mounting surface 905 and the cable assembly surface is an acute angle, and the clamping angle between the camera bracket mounting surface 905 and the housing mounting surface 904 is an acute angle.

[0039] like Figures 1-4As shown, the camera bracket mounting surface 905 in this embodiment has three first mounting holes 908, two of which are located on the upper side and one on the lower side. The cylindrical support mounting surface 903 has three second mounting holes 909, which are arranged one-to-one with the three first mounting holes 908 and connected and fixed by connectors. By providing three first mounting holes and three second mounting holes, the camera assembly is prevented from being reversed during on-orbit replacement, thus avoiding affecting the imaging effect. Furthermore, given the limited hand space and field of view at the bottom of the camera assembly, a first mounting hole on the lower side of the camera bracket mounting surface facilitates disassembly and assembly.

[0040] like Figure 2 and Figure 4 As shown, in this embodiment, the first camera bracket 901 is a C-shaped cylindrical structure, and the second camera bracket 902 is a plate-like structure. The open side of the C-shaped cylindrical structure of the first camera bracket 901 is detachably connected to the peripheral edge of the second camera bracket 902 via a connector. All three second mounting holes 909 are provided on the support mounting surface 903 of the first camera bracket 901. The camera components can be mounted and fixed on the first camera bracket, facilitating installation, replacement, and other operations.

[0041] like Figures 1-4 As shown, in this embodiment, one end of the cylindrical structure is a round hole structure adapted to the camera assembly, and the other end of the cylindrical structure is a square hole structure adapted to the camera bracket mounting surface 905 of the camera support 900.

[0042] like Figures 1-4 As shown, the mounting surface 904 of the housing in this embodiment is a flat surface or an L-shaped surface; the thickness of the camera bracket and the camera support 900 are 4-7 mm respectively. Different mounting surfaces can be used according to the requirements of the field of view inside the operating box.

[0043] like Figure 2 and Figure 4 As shown, in this embodiment, the first camera bracket 901 and the second camera bracket 902 are fastened together using a stop groove structure 910; the support mounting surface 903 of the camera bracket and the camera bracket mounting surface 905 on the camera support 900 are fastened together using a stop groove structure 910; the first camera bracket 901 or the second camera bracket 902 is also provided with a camera mounting hole 911 for connecting camera components. The use of the stop groove structure further improves the overall electromagnetic compatibility.

[0044] like Figures 1-4As shown, the first camera bracket 901 and the second camera bracket 902 can be connected and fixed using captive screws after being fastened together. The number of captive screws can be adjusted as needed for convenient on-orbit assembly and disassembly. The connection and fixation between the camera support 900 and the camera bracket can also be achieved using captive screws. The housing mounting surface 904 of the camera support 900 can be used to connect and fix to the inner wall of the operating box. The camera support is responsible for adjusting the required field of view angle of the camera assembly while ensuring the strength of the connection with the housing. The camera support 900 must ensure a reliable connection with the operating box housing, ensure sufficient rigidity to withstand the launch overload of the cantilevered camera, consider the overall electromagnetic compatibility of the camera assembly, and ensure that the camera's angle meets the field of view requirements. The local structure of the camera support 900 can be thickened, with a thickness of 6mm or more, to ensure that the cantilevered design can withstand the launch overload. The overall size of the camera mount is minimized as much as possible. Except for the cable channel, the other surfaces are all enclosed. The mounting surface that mates with the camera bracket adopts a stop groove design to improve overall electromagnetic compatibility. After mechanical analysis, the thickness of the mount is appropriately increased to improve its mechanical strength.

[0045] The on-orbit cantilever replaceable camera bracket used in the online cabinet of this embodiment is now subjected to mechanical tests, including acceleration tests, vibration tests, and impact tests. The acceleration test conditions, sinusoidal and random vibration test conditions, and impact test conditions are shown in the table below. The impact test conditions for the camera assembly are consistent with the component-level test level of the online maintenance operation support unit, referring to the component-level test level of the online maintenance operation support unit. This embodiment conducts mechanical environment tests on the online cabinet camera components according to the provisions of the "Outline for Mechanical Testing of Online Cabinet Camera Components" to assess the adaptability of the online cabinet rack products to the mechanical environment. The referenced documents are: "Outline for Evaluation and Testing of Online Maintenance and Adjustment Operation Cabinet Shelf Components of Space Application System Experiment Module II", "Requirements for Effective Payload Environmental Testing of Space Application System Experiment Module II of Manned Space Station Project", GJB 150.16A.-2009 "Methods for Laboratory Environmental Testing of Military Equipment Part 16: Vibration Test", "Design Scheme Report of Mechanical Environment Testing Fixture (Looking Down) for Experiment Cabinet", and GJB 1027A-2005 "Test Requirements for Launch Vehicles, Upper Stages and Spacecraft".

[0054] The allowable deviation for acceleration is 0–10%.

[0055] The permissible error for vibration frequency is ±2%.

[0056] The amplitude error of the sinusoidal sweep frequency vibration acceleration is ±10%;

[0059] Other permissible deviations for test conditions shall conform to GJB 1027A-2005;

[0060] The vibration table, testing equipment, and sensors used in the experiment were all calibrated and qualified by a third party. According to the actual test control curve, the vibration test conditions and process control met the requirements of the outline. During the acceleration, vibration, and impact tests on the camera assembly, after each test in one direction, the appearance of the camera, the appearance of its structural components, and the looseness of the focusing screws were checked. All inspection results were satisfactory. Simultaneously, after each test in each direction, the camera's imaging effect was tested. The test results showed that the camera's imaging effect was normal after the mechanical test, and the camera performance met the requirements for use in the online cabinet. After the test, a visual inspection of the tested product revealed no abnormalities in the camera, lens, or camera structural components, and the focusing screws were not loose. Before and after the tests in each direction, the product's imaging effect and other performance indicators showed no abnormalities, and the 0.2g characteristic level showed virtually no drift before and after the test. In summary, after the vibration test, the online cabinet camera assembly showed no abnormalities in its appearance, and the frequency drift met the requirements of the test outline; therefore, the test was successful.

[0061] like Figure 5 As shown, this embodiment also provides an online cabinet operation box, including a box body 1000 and an on-rail cantilever replaceable camera bracket for the online cabinet. The on-rail cantilever replaceable camera bracket for the online cabinet is provided at the top of each of the two opposite side walls of the box body 1000 at the diagonal position.

[0062] This embodiment of the online control cabinet reduces the volume occupied by the camera components by installing a camera bracket at the top of each of the two opposite side walls of the cabinet. This minimizes the volume occupied by the camera components and avoids interference between the camera components and the linear guide rails inside the control cabinet. Simultaneously, it prevents the brightness of the LED strip from affecting the camera's imaging effect. This online control cabinet, by employing two diagonally positioned camera brackets, provides a secure mounting method for observation cameras in large on-rail operating spaces. Through structural design, it ensures that the maximum field of view is covered with the fewest possible cameras, improving the ease of camera replacement.
