[0026] An embodiment of the utility model provides a simulation docking device for a space station interface, which can lock the spacecraft and the space station through a reinforcement mechanism, thereby increasing the stability between the spacecraft and the space station, and solving the problem of difficulty in ensuring the stability of the docking between the spacecraft and the space station in the above-mentioned technology.

[0027] See also Figure 1 A space station model 2 is fixedly installed on the top surface of the simulation platform 1. The simulation platform 1, space station model 2, spacecraft model 6, and electric linear slide rail 702 involved in this application are all existing technologies and will not be described in detail in this application.

[0028] See also Figure 1and Figure 3 One end of the space station model 2 is fixedly connected to a docking joint 3, and the outer surface of the docking joint 3 is fixedly connected to a group of cone sleeves 4. A snap-in hole 5 is opened inside each cone sleeve 4, and each cone sleeve 4 is respectively adapted to the corresponding spacecraft model 6. The cone sleeve 4 can realize the simulated connection process between the space station model 2 and the spacecraft model 6. The snap-in hole 5 can limit the sliding reinforcement rod 807 extending from the inside of the cone probe 801, so that the cone probe 801 remains stable, thereby improving the stability of the connection between the space station model 2 and the spacecraft model 6.

[0029] See also Figure 1 and Figure 2 Three spacecraft models 6 are arranged above the simulation platform 1, and three moving mechanisms 7 are arranged inside the simulation platform 1. Through the setting of the moving mechanisms 7, the spacecraft models 6 can be driven to simulate the movement of the spacecraft in space, thereby improving the simulation effect of the device.

[0030] See also Figure 2 and Figure 4 Three reinforcement mechanisms 8 with locking functions are arranged above the simulation platform 1. The reinforcement mechanisms 8 include cone probes 801. The three spacecraft models 6 are fixedly connected to the three cone probes 801 respectively. When the cone probes 801 are fixedly connected to the cone sleeve 4, it can ensure that the spacecraft model 6 is fixedly connected to the cone sleeve 4, thereby increasing the stability of the device.

[0031] See also Figure 1 and Figure 2 The moving mechanism 7 includes a moving slide groove 701 opened on the top surface of the simulation platform 1, and the inner wall of the moving slide groove 701 is fixedly connected with an electric linear slide rail 702, and the outer surface of the electric linear slide rail 702 is slidably connected with a slider 703. The electric linear slide rail 702 is driven by a motor, and the motor is powered by a DC or AC power supply. The motor is driven to operate through a circuit controller, which can drive the slider 703 to slide on the surface of the electric linear slide rail 702, thereby driving the spacecraft model 6 to simulate the movement of the spacecraft during the docking process.

[0032] The top surface of the slider 703 is fixedly connected to a connecting column 704, and the outer surface of the spacecraft model 6 is provided with a slot, which is adapted to the connecting column 704. The connecting column 704 is engaged in the slot provided on the outer surface of the spacecraft model 6. When the slider 703 moves, it can drive the connecting column 704 to move, thereby driving the spacecraft model 6 to move, providing power for the docking of the spacecraft model 6 with the space station model 2.

[0033] See also Figure 2 , Figure 4 and Figure 5The interior of the cone probe 801 is slidably connected to a sliding column 802, and the bottom end of the sliding column 802 is fixedly connected to a compression spring 803. The end of the compression spring 803 away from the sliding column 802 is fixedly connected to the cone probe 801. During the docking process between the spacecraft model 6 and the cone sleeve 4, the inner wall of the cone sleeve 4 will squeeze the sliding column 802, and the sliding column 802 will be compressed by the compression spring 803, thereby causing the sliding column 802 to slide inside the cone probe 801.

[0034] The outer surface of the sliding column 802 is fixedly connected to a fixing ring 804, and the outer surface of the fixing ring 804 is fixedly connected to a group of transmission blocks 805. When the sliding column 802 slides inside the cone probe 801, it can drive the fixing ring 804 to slide inside the cone probe 801, and the sliding of the fixing ring 804 can drive the transmission block 805 to slide.

[0035] Each transmission block 805 is hinged with a transmission rod 806 via a pin, and the bottom end of each transmission rod 806 is hinged with a sliding reinforcement rod 807 via a pin. When the transmission block 805 slides inside the cone probe 801, the transmission rod 806 can be driven to move through the hinge of the pin.

[0036] The sliding reinforcement rod 807 passes through the cone probe 801 and is slidably connected to the cone probe 801. The snap-in hole 5 is adapted to the sliding reinforcement rod 807. The movement of the transmission rod 806 can drive the sliding reinforcement rod 807 to slide out from the inside of the cone probe 801. After the sliding reinforcement rod 807 slides out, it will snap into the snap-in hole 5, thereby increasing the stability of the docking between the space station model 2 and the spacecraft model 6.

[0037] Working principle: at the beginning of the simulated docking, the motor connected to the electric linear slide 702 is started, driving the slider 703 to slide on the outer surface of the electric linear slide 702, and the sliding of the slider 703 drives the connecting column 704 to move, thereby driving the spacecraft model 6 to move. When the spacecraft model 6 moves to the inside of the cone sleeve 4, the inner wall of the cone sleeve 4 will squeeze the sliding column 802, and the sliding column 802 is forced to compress the compression spring 803, so that the sliding column 802 itself slides inside the cone probe 801, and the sliding column 802 slides and drives the fixing ring 804 to slide. Through the transmission effect of the transmission block 805, the transmission rod 806 will also move inside the cone probe 801. The movement of the transmission rod 806 drives the sliding reinforcement rod 807 to slide out of the inside of the cone probe 801. After sliding out, the sliding reinforcement rod 807 will be engaged with the engaging hole 5, thereby increasing the stability of the docking between the space station model 2 and the spacecraft model 6 and improving the accuracy of the simulation.

Those skilled in the art should understand that the utility model is not limited by the above embodiments.
