[0002] With the rapid development of my country's science and technology, my country has also achieved rapid development in the field of aerospace. The duration of each space flight of astronauts has become longer and longer. During long-term space flight, resistance training in a microgravity environment is an important protective measure against muscle atrophy and bone loss in medium- and long-term manned space flight. Its main function is to make the muscles contract by overcoming a certain load, while giving the bones a certain pulling stimulation, causing bone remodeling, thereby effectively combating muscle atrophy and bone loss. Its main function is to provide resistance and corresponding accessories, and meet the movement requirements of exercise in a weightless environment.

[0003] However, the inventors believe that existing fitness equipment has the following defects: traditional fitness equipment has relatively single functions, and upper limb exercises and lower limb exercises are usually performed separately. The internal space in the spacecraft is relatively limited, and it is difficult to place more training equipment at one time. Astronauts need comprehensive exercise to ensure the normal operation of various body functions during long-term space flight.

[0004] Therefore, the prior art needs to be improved. Summary of the invention

[0028] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. The components of the embodiments of the present application described and shown in the drawings here can be arranged and designed in various different configurations.

[0029] The following is combined with Figure 1-6 This application is described in further detail.

[0030] Example

[0031] The embodiment of the present application discloses an upper and lower limb exercise device suitable for use in a weightless environment.

[0032] Reference Figure 1 , 2 A device for exercising upper and lower limbs in a weightless environment comprises a mounting frame 1, a resistance source 11 is arranged on the mounting frame 1, a resistance shaft 12 is rotatably arranged on the resistance source 11, a connecting rod 13 is arranged on the resistance shaft 12, a force pedal 2 is arranged at one end of the connecting rod 13 away from the resistance shaft 12, a force member 3 is arranged on the force pedal 2, the force member 3 is used to drive the connecting rod 13 to rotate, the force member 3 and the force pedal 2 are detachably connected, a restraint assembly 4 is arranged on the mounting frame 1, and the restraint assembly 4 is used to limit the position of the trainee on the mounting frame 1.

[0033] Among them, refer to Figure 1The restraint assembly 4 includes a waist restraint belt 41, an armrest 42 and a neck restraint plate 43. In the actual training process, the waist and abdomen of the astronaut are limited by the waist restraint belt 41, which can effectively prevent the astronaut from shifting his body position due to weightlessness during training. In the process of lower limb exercise, the astronaut can grasp the armrest 42 with his hands, and the astronaut's shoulder and neck are abutted and limited by the neck restraint plate 43, which further improves the standard of the astronaut's posture during exercise and avoids the decline of training effect or even accidental body injury due to deviation of posture.

[0034] Reference Figure 1 As an implementation mode of the present application, the waist restraint belt 41, the armrests 42 and the neck restraint plate 43 can be detachably arranged on the mounting frame 1. According to the different body shapes of different astronauts, the positions of the restraint belt, the armrests 42 and the neck restraint plate 43 on the mounting frame 1 are adjusted, thereby significantly improving the application scope of the device, enabling astronauts of different body shapes to obtain better restraint and fixation effects during training, thereby ensuring the normal and healthy progress of the training.

[0035] Reference Figure 1 , 2 As an implementation mode of the present application, the resistance source 11 is configured as a resistance generator, which drives the resistance shaft 12 to rotate to drive the resistance generator to generate electricity. The resistance generator is electrically connected to a resistance resistor. As the current emitted by the resistance generator causes the resistance resistor to heat up and do work, the electrical energy emitted by the resistance generator is consumed. By adjusting the current loaded on the resistance resistor, the work required to drive the resistance motor to generate electricity can be adjusted, thereby adjusting the torque required for the resistance shaft 12 to rotate. Similar technical solutions already exist on existing fitness bikes and will not be repeated here.

[0036] As an implementation method of this application, refer to Figure 1 , 2 The force applying member 3 is configured as a handle. A first connecting plate 5 is fixedly disposed at one end of the handle close to the force applying pedal 2, and a second connecting plate 6 is disposed at one end of the first connecting plate 5 away from the handle.

[0037] Among them, refer to Figure 3 , 4 A through mounting hole 61 is provided on the second connecting plate 6. As an embodiment of the present application, three mounting holes 61 are provided. The three mounting holes 61 are triangularly distributed and evenly arranged on the second connecting plate 6. A connecting bolt 62 is slidably arranged in each mounting hole 61. A threaded hole 51 for threaded connection of the connecting bolt 62 is provided at one end of the first connecting plate 5 away from the handle. The position of the threaded hole 51 on the first connecting plate 5 is adapted to the position of the mounting hole 61 on the second connecting plate 6.

[0038] Reference Figure 3 , 4 A sink groove 63 is provided at one end of the second connecting plate 6 away from the first connecting plate 5. The number of the sink grooves 63 matches the mounting hole 61. The sink groove 63 is in the shape of a square groove. The sink groove 63 is connected to the mounting hole 61. A gasket 64 is provided in the sink groove 63. The shape and size of the gasket 64 match the sink groove 63. One end of the gasket 64 abuts against the bottom wall of the sink groove 63, and the other end abuts against the connecting bolt 62. By providing the gasket 64, the tightness of the connection between the first connecting plate 5 and the second connecting plate 6 can be effectively improved, thereby improving the stability of the device as a whole during use.

[0039] Reference Figure 4 As an embodiment of the present application, a plurality of abutment sheets 65 are fixedly provided on one side of the second connecting plate 6 close to the first connecting plate 5. When the first connecting plate 5 is connected and fixed to the second connecting plate 6, the abutment sheet 65 abuts against the bottom of the first connecting plate 5 on the side away from the second connecting plate 6. Usually, the abutment sheet 65 is made of a soft material with a certain elastic potential energy such as sponge or rubber, and has a certain elastic modulus, which has a certain degree of protection effect on the connecting surface of the first connecting plate 5 and the second connecting plate 6, thereby effectively improving the service life of the device.

[0040] As an implementation method of this application, refer to Figure 3 , 4 5 , the second connecting plate 6 is detachably connected to the force pedal 2 , and a limiting member 7 is provided on the force pedal 2 , and the limiting member 7 is used to limit the position of the second connecting plate 6 on the force pedal 2 .

[0041] Among them, refer to Figure 4 , 5 A first clamping strip 66 is fixedly provided on one side of the second connecting plate 6 away from the first connecting plate 5 , a first clamping slot 8 is provided on the force pedal 2 , and the first clamping strip 66 is adapted to the first clamping slot 8 .

[0042] As an implementation method of this application, refer to Figure 4 , 5 The limiting member 7 is configured as a second clamping strip. The second clamping strip is rotatably disposed at one end of the force pedal 2 away from the first clamping slot 8, and a second clamping slot 71 for the second clamping strip to be clamped into is provided on the second connecting plate 6.

[0043] During actual use, the first connecting plate 5 is first tilted slightly so that the first clamping strip 66 is inserted into the first clamping groove 8, and then the first connecting plate 5 is rotated so that the first connecting plate 5 and the second connecting plate 6 are abutted against each other. At this time, the second clamping strip is inserted into the second clamping groove 71, so that the position of the second connecting plate 6 on the force pedal 2 can be limited, completing the installation of the handle.

[0044] Among them, refer to Figure 4 , 5 The side wall of the second clip strip is set as an inclined surface, and the side wall of the second clip strip is gradually contracted in the direction away from the rotation axis of the second clip strip, and the side wall of the second slot 71 is adapted to the side wall of the second clip strip.

[0045] During actual use, when the handle needs to be disassembled, the second connecting plate 6 is driven to rotate in the direction away from the resistance source 11. At this time, since the side walls of the second clamping strip and the side walls of the second clamping slot 71 are both inclined, and the inclination direction of the side walls of the second clamping strip gradually shrinks in the direction away from the second clamping strip rotation axis, as the second connecting plate 6 rotates, the side walls of the second clamping strip abut against the side walls of the second clamping slot 71. As the second connecting plate 6 rotates further, the second clamping strip can be driven to deflect in the direction away from the second clamping slot 71, thereby releasing the limitation of the second clamping strip on the position of the second connecting plate 6, and then the handle can be disassembled.

[0046] As another embodiment of the present application, refer to Figure 6 The force applying member 3 is set as a sports shoe, and the first connecting plate 5 is fixedly arranged on the sole of the sports shoe.

[0047] Among them, refer to Figure 1 The device also includes a display 9, which is electrically connected to the resistance source 11 through wires and data cables. During the actual training process, the power generation of the resistance generator and the resistance of the resistance resistor are transmitted to the display 9 in real time through the wires and data cables, and the exercise time, specific rotation speed, specific exercise intensity and other parameters can also be displayed, so that the astronauts in the training process can understand the real-time training status. Since the training is in a weightless or microgravity environment, there is no need for a rigid connection between the display 9 and the mounting frame 1, and the position of the display 9 can be arbitrarily placed within a certain space range, so that the astronauts can easily understand their own training status through the display 9 regardless of whether they are exercising their lower limbs or upper limbs.

[0048] The implementation principle of the upper and lower limb exercise device suitable for a weightless environment in the present application is as follows:

[0049] In actual use, since the use environment is a weightless or microgravity environment, in this environment, astronauts can overcome the normal gravity environment on the earth and perform different training movements. When lower limb exercise is required, the force-applying member 3 is replaced with a sports shoe, and the second connecting plate is clamped with the force-applying pedal 2. At this time, the astronaut puts on the sports shoe, and limits the position of the body on the mounting frame 1 through the binding component 4, and then turns on the resistance source 11, and then the lower limb exercise can be started, and this posture is regarded as the normal state; when upper limb exercise is required, the position of the second connecting plate 6 on the force-applying pedal 2 by the limiting member 7 is released, and then the connection between the first connecting plate 5 and the second connecting plate 6 is released, and then the sports shoe can be replaced with a handle, and then the connection between the first connecting plate 5 and the second connecting plate 6, and the connection between the second connecting plate 6 and the force-applying pedal 2 are completed in sequence, and then the astronaut is reversed relative to the normal state of the body, grasps the handle with his hand, and limits the position of the body on the mounting frame 1 through the binding component 4, and then the resistance source 11 is turned on, and then the upper limb exercise can be started;

[0050] By replacing different force-applying members 3 and utilizing the weightlessness or microgravity environment in space, the body posture can be arbitrarily changed to achieve the effect of upper and lower limb training, which effectively saves the space in the spacecraft and enables astronauts to make full use of the limited space in the spacecraft to conduct comprehensive and effective upper and lower limb training, thereby politely ensuring that the astronauts' body functions can operate normally during long-term space flight.

[0051] The above are only preferred embodiments of the present application and are not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
