Technical Field

[0001] The present application relates to a space station experimental device and an experimental device and a sample device thereof. Background Art

[0002] The space station is equipped with space station experimental equipment for various space experiments to conduct various experiments on samples, such as space electrical parameter measurement. Among them, the samples are sent to the space station by cargo spacecraft and installed in the space station experimental equipment to conduct various experiments on the samples. Afterwards, the samples are recovered and brought back to the ground by the cargo spacecraft to be compared with the ground data. During the installation and recovery of the samples, astronauts are required to operate outside the space station cabin. Due to the special requirements of the space station samples, the samples are small in size, resulting in a small operating space for astronauts. At the same time, astronauts working outside the cabin are in a suspended operating state, which increases the difficulty of operation. Therefore, the plugging and unplugging methods involved in the installation and recovery of the samples need to fully consider ergonomics, and need to ensure that the samples are installed in place, positioned correctly, firmly and stably, which is quite difficult.

The upper cantilever and the lower cantilever can rotate around the rotating shaft so that the locking mechanism switches between a locked position and a released position. The end of the upper cantilever has a pressing mechanism and a protrusion. The locking mechanism is mounted on the back side of the baffle. The lower cantilever extends downward so that the hook-shaped end passes over the third side of the baffle.

[0009] When the locking mechanism is in the locking position, the protrusion passes through the through hole in the baffle and protrudes to the front side of the baffle; when the locking mechanism is in the releasing position, the protrusion retracts to the back side of the baffle;

[0010] During the process of switching the locking mechanism from the locking position to the releasing position, the rotation of the lower cantilever causes the hook-shaped end to be lifted upward; during the process of switching the locking mechanism from the releasing position to the locking position, the rotation of the lower cantilever causes the hook-shaped end to fall downward.

[0030] During the process of pressing the first cover body and the second cover body downward along the baffle, the protrusion first retracts to the back side of the baffle under the action of the first cover body and the second cover body, so that the locking mechanism is in a released position, and then, as the first cover body and the second cover body slide further downward, the position of the locking hole is aligned with the protrusion. At this time, the protrusion passes through the through hole in the baffle and protrudes to the front side of the baffle and extends into the locking hole, so that the locking mechanism is in a locked position.

[0031] An embodiment of the present application provides a space station experimental device, wherein when the sample device needs to be removed from the experimental device,

[0032] The pressing mechanism is pressed to switch the locking mechanism from the locking position to the releasing position. During the switching process, the rotation of the locking mechanism causes the hook-shaped end to lift upward and the protrusion to retract to the back side of the baffle.

[0033] The lifting of the hook-shaped end causes the first cover body and the second cover body to lift upward, and at the same time, the retraction of the protrusion releases the first cover body and the second cover body, so that the first cover body and the second cover body can continue to slide upward and release the clamping effect of the second locking mechanism on the first cover body and the second cover body.

[0046] In order to have a clearer understanding of the technical features, purposes and effects of this application, the specific implementation methods of this application are now described with reference to the accompanying drawings.

[0047] According to one embodiment of the present application, the space station experimental equipment includes an experimental device and a sample device. The experimental device is fixed in the space station, and the sample device is sent to the space station by a cargo spacecraft and installed on the experimental device to perform various experiments on the samples carried in the sample device. Afterwards, the sample device is disassembled from the experimental device and brought back to the ground by the cargo spacecraft.

[0048] According to an embodiment of the present application, the space station experimental equipment includes an experimental device 1 and a sample device 2. Figure 1 As shown, the experimental device 1 includes:

[0049] An experimental device body 10, one end of which has a baffle 11 for connecting with a sample device;

[0050] Two first locking mechanisms 12 are respectively located on the first side and the second side of the baffle 11 and protrude from the baffle 11. The first locking mechanisms 12 are in the shape of upwardly curved hooks and are used to limit the sample device;

[0051] The second locking mechanism 13 is located on the third side of the baffle 11 and is used to limit the sample device. The second locking mechanism 13 has a first electrical connector for achieving electrical connection between the experimental device and the sample device.

[0052] The two locking mechanisms 14 are used to lock the sample device to the baffle 11 after the sample device is in place, and to assist the astronauts in quickly removing the sample device from the experimental device 1 when recovering the sample device. Figure 2An enlarged schematic diagram of the locking mechanism 14 is shown. The locking mechanism 14 has a rotating shaft 141, an upper cantilever 142, and a lower cantilever 143 fixed to the main body 10 of the experimental device. The upper cantilever 142 and the lower cantilever 143 can rotate around the rotating shaft 141 between a first position and a second position. The lower cantilever 143 has a hook-shaped end 144. The end of the upper cantilever 142 has a pressing mechanism 145 and a protrusion 146. The pressing mechanism 145 and the protrusion 146 extend in opposite directions. The protrusion 146 is a right triangle, and one side of its hypotenuse faces upward. As shown in FIG. Figure 1 As shown, the locking mechanism 14 also has a return spring 147, one end of which is connected to the experimental device body 10, and the other end is connected to the pressing mechanism 145 at the end of the upper cantilever 142. Figure 1 As shown, the locking mechanism 14 is mounted on the back side of the baffle 11, and its protrusion 146 can pass through the through hole in the baffle 11 and protrude to the front side of the baffle 11. The hook-shaped end 144 of the lower cantilever 143 of the locking mechanism 14 extends downward over the third side of the baffle 11. When the sample device is mounted on the experimental device 1, the hook-shaped end 144 contacts one side of the sample device.

[0053] like Figure 3 and Figure 4 As shown, a sample device 2 according to an embodiment of the present application includes:

[0054] The first cover 21 and the second cover 22 can rotate around a pivot 23 to switch between a closed state and an open state. Figure 3 As shown, the first cover 21 and the second cover 22 form a box body with a receiving space for protecting the sample 24 carried inside the box body. Figure 4 As shown, the first cover 21 and the second cover 22 are located in the same plane;

[0055] The second electrical connectors 25 and 26 are located on one side of the first cover 21 and the second cover 22 and are used to cooperate with the first electrical connector in the second locking mechanism 13 to achieve electrical connection;

[0056] A first handle 27 and a second handle 28 are respectively located on the outside of the first cover 21 and the second cover 22 and are used to assist in holding the sample device 2;

[0057] Two locking holes 31 are respectively located on the outer sides of the first cover 21 and the second cover 22 at positions corresponding to the first locking mechanism 12 of the experimental device 1;

[0058] The two locking holes 32 are respectively located on the outer sides of the first cover 21 and the second cover 22 at positions corresponding to the protrusions 146 of the locking mechanism 14 of the experimental device 1 .

[0059] Figure 5 The process of installing the sample device 2 on the experimental device 1 and the process of removing the sample device 2 from the experimental device 1 are shown, wherein for the sake of clarity, Figure 5 The return spring 147 is omitted.

[0060] like Figure 5 As shown, when the sample device 2 needs to be installed on the experimental device 1, the first cover 21 and the second cover 22 of the sample device 2 are first opened to Figure 4 The first cover 21 and the second cover 22 are then placed close to the baffle 11 of the experimental device 1, so that the locking holes 31 on the first cover 21 and the second cover 22 are aligned with the first locking mechanism 12 of the experimental device 1, and the first locking mechanism 12 extends into the locking holes 31. The first cover 21 and the second cover 22 are then pressed downward along the baffle 11 until the first cover 21 and the second cover 2 are locked by the second locking mechanism 13, and the electrical connection between the second electrical connectors 25 and 26 of the first cover 21 and the second cover 22 and the first electrical connector in the second locking mechanism 13 is completed.

[0061] As the first and second covers 21, 22 are pressed downward along the baffle 11, the protrusion 146 of the locking mechanism 14 first retracts to the back side of the baffle 11 under the action of the first and second covers 21, 22. At this point, the locking mechanism 14 is in the first position, i.e., the released position. Then, as the first and second covers 21, 22 slide further downward, the locking holes 32 of the first and second covers 21, 22 align with the protrusion 146 of the locking mechanism 14. At this point, the protrusion 146, under the action of the return spring 147, passes through the through hole in the baffle 11, protrudes to the front side of the baffle 11, and extends into the locking hole 32, thereby limiting the first and second covers 21, 22. At this point, the locking mechanism 14 is in the second position, i.e., the locked position.

[0062] like Figure 5As shown, when the sample device 2 needs to be removed from the experimental device 1, the pressing mechanism 145 at the end of the upper cantilever 142 of the locking mechanism 14 is first pressed to overcome the action of the return spring 147, thereby rotating the locking mechanism 14 about its rotation axis 141, thereby switching the locking mechanism 14 from the locked position to the released position. During the switching process, the rotation of the locking mechanism 14 causes its hook-shaped end 144 to rise upward and its protrusion 146 to retract to the back side of the baffle 11. The lifting of the hook-shaped end 144 enables the first and second covers 21 and 22 of the sample device 2 to overcome the locking action of the second locking mechanism 13 and rise upward. At the same time, the retraction of the protrusion 146 releases the first and second covers 21 and 22, allowing them to continue sliding upward and releasing the locking action of the second locking mechanism 13 on the first and second covers 21 and 22, thereby allowing the first and second covers 21 and 22 to be removed from the experimental device 1.

[0063] Then, the first cover 21 and the second cover 22 of the sample device 2 are closed. Figure 3 Shown in closed state.

[0064] In the space station experimental equipment provided by this application, its experimental device and sample device adopt structures such as snaps and positioning devices, and complex mechanical requirements can be achieved with simple actions. Among them, the space station experimental equipment can assist astronauts in quickly positioning and installing the sample device. The locking mechanism 14 can automatically complete the locking action after the sample device is installed in place, and the astronauts do not need to perform an extra step. The positioning mechanism and the locking mechanism are both mechanical structure designs, without power consumption. Under space station conditions, they are efficient, energy-saving, safe and reliable. At the same time, the locking mechanism is an auxiliary operating device when the sample structure needs to be removed to complete the space mission, which can help astronauts quickly take away the sample.

[0065] The positioning structure of the experimental device and the sample device, combined with the structure of the sample device, helps astronauts quickly locate the installation location and secures the sample device once it is in place. Once the sample is in place, the locking mechanism 14, under the pressure of the return spring 147, presses the protrusion 146 of the upper cantilever 142 against the sample device.

[0066] When the astronauts need to remove the sample device, they only need to gently press down the pressing mechanism 145 at the upper end of the locking mechanism 14, and the hook-shaped end 144 at the lower end of the locking mechanism 14 will lift the sample device to separate it from the experimental device, and the retrieval action can be completed in just one step.

[0067] After the astronauts quickly pull out the sample device, they only need to follow the steps below Figure 4 The method shown is to quickly close the Figure 3In the state shown, the sample is fixed in the sample device, and the sample device forms a shell to well protect the sample when it returns.

[0068] The space station experimental equipment provided in this application can reduce the volume to the range of (145mm length)*(99mm width)*(29.2mm height), control the weight within 300g, and control the astronaut operation time within 20 seconds.

This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.

[0070] The above description is only an illustrative embodiment of the present application and is not intended to limit the scope of the present application. Any equivalent changes, modifications and combinations made by any person skilled in the art without departing from the concept and principle of the present application shall fall within the scope of protection of the present application.
