Description

Technical Field

[0001] The utility model relates to the technical field of space station equipment, in particular to a reconfigurable space cabinet. Background Art

[0002] As the space station is completed and enters the operation and development stage, the demand for space experiments has experienced explosive growth. Space cabinets are the basic units for on-orbit experiments on the space station. Currently, space cabinets are fixedly installed on the cabin and carried up with the cabin, and can only be used in situ.

[0003] Therefore, the following problems may occur:

[0004] 1) Since the space cabinet is fixedly installed and carried up with the cabin, the cabinet development progress affects the cabin launch progress. When the cabinet belongs to multiple systems, the impact is even greater;

[0005] 2) The space cabinet is heavy, and the cabin load-bearing structure needs to be specially strengthened when it is launched uplink, which increases the launch cost;

[0006] 3) The space cabinet is large in size and difficult to disassemble and move as a whole on track, wasting precious limited space resources;

[0007] 4) The function of the space cabinet is relatively single and can only be used in situ. After the single function test is completed, it is idle, which reduces the output of the space test benefits. Utility Model Content

[0054] Furthermore, by manually adjusting the captive screw 103 and manually unlocking the locking structure 6 of the support rod 3, that is, longitudinally stretching the rod 101, the support rod 3 is extended to the locking structure 6 to automatically lock and complete the fixation of the support rod 3 for the secondary longitudinal expansion of the space cabinet.

[0055] Furthermore, the cabinet further comprises: a fixing strap for fixing the main truss 1 in the folded state.

[0056] Furthermore, cabinet fixing rails 4 are provided on both sides of the bottom of the main truss 1 for mounting the space cabinet on the base 5 .

[0057] Specifically, the utility model provides a reconfigurable space cabinet, which includes 6 main trusses 1, 14 folding rods 2, 10 support rods 3, a plurality of host slide rails 4 and 2 sets of space cabinet bases 5.

In the contracted state, part of the rod 101 is located inside the main truss sleeve 102, and the main truss rod 101 is fixed by a captive screw 103 installed on the main truss sleeve 102. Before extension, the captive screw 103 is unlocked, and the main truss rod 101 is manually pulled to slide along the sleeve 102 into place, and the rod 101 is completely extended out of the sleeve 102.

[0059] The folding rod 2 is a two-section folding structure, which is installed at the ends of adjacent main truss rods 101 through two rotating pairs, and the rotating pairs are connected between the rods 101; when the space cabinet is unfolded, the folding rod 2 extends outward, and the two sections of the rods 101 rotate around the rotating axis, and the angle between the rods 101 changes from 0° to 180°; when the space cabinet is folded, the folding rod 2 is folded inward, and the angle between the rods 101 changes from 180° to 0°; the three rotating pairs work simultaneously to realize the unfolding or folding action of the folding rod 2.

[0063] The main truss 1 and the folding rod 2 of the space cabinet, as well as the main truss 1 and the support rod 3 are connected by a revolute pair. When the space cabinet is folded, the main truss 1 is horizontally unfolded, and the folding rod 2 and the support rod 3 rotate around the revolute pair respectively. The support rod 3 is axially extended to the locking structure 6 and automatically locked. At this time, the folding rod 2 is synchronously extended to the position, and the horizontal unfolding of the space cabinet is completed;
