Technical Field

The invention relates to the technical field of human body position limitation in a service cabin of a space station, in particular to a wearable human body position limiting device under a weightless condition.

Background

In the space station service cabin, due to the lack of gravity, the human foot and the contact surface lack acting force, so that the human foot cannot be stably connected with the contact surface, and the human body is in a floating state. In this floating state, the astronaut cannot maintain a stable position without assistance. This places restrictions on both life and work within the service bay of the space station for the astronaut. For this reason, various in-cabin position restricting devices have been developed to assist the astronaut in position restriction. The human body position limiting device in the cabin is mainly a foot limiter. The foot restraint provides great convenience for the life and work of the astronaut in the cabin, but still has some problems worthy of improvement. One is poor flexibility of use. The foot limiter is connected with the interface of the inner surface of the cabin through the interface device, and the position of the interface in the cabin is relatively fixed, so that the astronaut can obtain the position limiting effect only at the position where the interface and the foot limiter are arranged. Meanwhile, in order to save the launching cost, the maximum position limiting range is usually realized by using the minimum foot limiters, so that the astronaut is easy to be in an unconventional body posture in the position limiting process, and discomfort such as muscle soreness is caused. Secondly, the position restriction stability is poor. When the feet are used for position fixing, stable contact force cannot be formed between the auxiliary fixing devices and the feet, so that the toes of the feet need to be continuously raised when the feet of the astronauts are used for position fixing, and the muscles of the lower limbs (particularly the tibialis anterior muscles) are uncomfortable and even damaged due to long-time continuous exertion. Thirdly, in emergency, due to the lack of a foot limiter fixing interface, the human body is helped to obtain a fixed position, so that the personnel cannot effectively deal with the police situation in time, and an adverse task event can be generated, thereby threatening the flight task.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

The invention aims to provide a wearable human body position limiting device under a weightless condition so as to achieve good position limitation at different positions in a cabin.

In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in further detail below.

As shown in fig. 1-2, the invention discloses a wearable human body position limiting device under weightless condition, which is characterized in that the device comprises: a foot connecting part 1, a connecting layer 2 and an adhesion layer 3; the foot connecting part 1 is connected with the foot of a human body in a wearing way; the connecting layer 2 is used for connecting the foot connecting part 1 and the adhesion layer 3; the adhesive layer 3 is used for connecting the human foot and the contact surface by Van der Waals force.

As an embodiment, the foot connecting part 1 of the present invention includes a strap 11 and a connecting plate 13, and the strap 11 is connected to the connecting plate 13; the connecting plate 13 is used for placing feet, and the bandage 11 is used for connecting the connecting plate 13 with the feet. As a best mode, the foot connecting part 1 is a shoe, and the connecting layer 2 and the adhesion layer 3 are directly adhered to the sole, so that the cost of the whole device is reduced.

This embodiment can be according to the size and the adjustable elasticity of comfortable degree of human foot, stability and travelling comfort in the assurance use.

In one embodiment, the connection layer 2 is a fixing adhesive, and the adhesion layer 3 and the connection plate 13 are fixedly connected by the fixing adhesive, so that the connection stability is improved.

In one embodiment, the adhesion layer 3 of the present invention is a ciliated structure with a nano-scale diameter, and the ciliated structure has a nano-scale diameter and forms a reliable van der waals force with the contact surface, so that a human body wearing the position restriction device can form a stable contact with the contact surface. The magnitude of the van der waals force can be changed by changing the area size (number of cilia) of the adhesive layer 3 and the roughness of the contact surface, thereby obtaining different magnitude of contact force between the position restricting means and the contact surface.

The position limiting device disclosed by the invention is applied to the experimental process of the chest expander exercise, the weight of a human body is reduced through the suspended weight reducing system, the mechanical condition simulating weightlessness is established, and the chest expander pull-down exercise actions of the human body under the mechanical condition simulating weightlessness when the user wears the position limiting device and does not wear the position limiting device are respectively simulated by the user. The method comprises the steps of obtaining a kinematics video, analyzing based on the kinematics video, and when a human body does pull-down exercise by a chest developer without wearing the position limiting device, because the feet and the working surface of the foot do not have stable contact force, the human body is influenced by upward reaction force to move upwards, and the feet leave the working surface, so that the human body cannot finish the pull-down exercise. Therefore, under the condition of weightlessness, the foot part does not have stable contact force with the working surface, so that the human body cannot complete protective exercise actions such as pulling down, and the like, and therefore, the on-orbit operation with similar force action effect cannot be completed. When a user wears the position limiting device, the body is also influenced by the upward reaction force when the user pulls down the chest expander, but the position limiting device can provide enough stable contact force for the user, so that the user can complete the pulling-down action of the chest expander and the on-orbit operation with similar force action effect.

In the embodiment, the position limiting device is arranged to stably connect the footsteps of the human body with the contact surface, so that the human body can obtain a stable position limiting effect under a weightless condition, a spaceman can obtain a good position limiting effect at different positions in the cabin, the problems of poor position limiting stability and poor use flexibility of the traditional position limiting device are greatly improved, and meanwhile, the probability that the spaceman is in an uncomfortable body posture in position limitation is reduced, so that the human body applicability in position limitation is greatly improved.
