Abstract
Description
Technical Field
[0001] The present invention belongs to the field of exoskeleton robots, and in particular relates to a wearable protective armor exoskeleton. Background Art
[0002] A wearable exoskeleton is a wearable intelligent power-assisting device that can assist the human body in walking, carrying and other tasks by coordinating movements with the wearer, reducing fatigue and damage to the human body caused by movement, and improving the body's functions. Its application areas are very wide. In the military field, it can improve the soldiers' flexibility, mobility, load-bearing capacity, etc.; in dangerous combat environments, exoskeletons with protective devices can more effectively protect the lives of soldiers. At present, exoskeleton robots have bulky structures, poor wearing comfort, complex control systems, and limited power-assisting effects, which makes the soldiers have to bear a huge load. In addition, existing exoskeletons do not have the function of carrying protective devices and providing power assistance at the same time, which is still a problem that needs to be solved urgently.
[0003] For example, the Chinese patent application with application number 201610520405.7 discloses a lower limb power-assisted mechanical exoskeleton that simulates the structure of human legs and has mechanical legs on the left and right sides of the human legs. However, this anthropomorphic design causes the load force to act outside the plantar support surface, the force transmission design is unreasonable, and the power-assisted effect is average. At the same time, the patent application does not have the function of adjusting the length of the mechanical legs, and has poor adaptability to the wearer; moreover, the articulated mechanical joint structure cannot meet the movement needs of the human body, and there is movement interference between man and machine; in addition, the knee joint drive mechanism of the lower limb power-assisted mechanical exoskeleton of the above patent application adopts a cable drive, the mechanism design is complex, the manufacturing and assembly are difficult, and the control accuracy is poor.
[0004] For example, the Chinese patent application with application number 201820525967.5 discloses a wearable mechanical exoskeleton for upper body protection of the human body. Although it can realize multi-degree-of-freedom and all-round movement of the upper body of the human body, and is compatible with anti-fall vests, bulletproof vests, and lower limb exoskeletons for safety protection, this design method causes the forces of the upper body protection device and the exoskeleton to act on the human body at the same time, which imposes a huge load on the operator while the protection coverage area is small. In addition, the wearable mechanical exoskeleton for upper body protection of the human body in the above patent application has a complex design, is difficult to manufacture and assemble, has poor control accuracy, and cannot meet the requirements of quick donning.

The back drive motor 10-5 is installed on the motor fixed end 10-4 by screws, and the rotating part of the motor is connected to the torque sensor 10-3. The back drive motor 10-5 and the motor fixed end 10-4 are connected to the torque sensor 10-3 by bolts, and the back connecting rod 10-6 is connected to the torque sensor 10-3 by screws, and the torque sensor 10-3 is connected to the back connecting rod 10-6 by screws. The power assist from bending to upright state is achieved by using the back drive motor 10-5 to rotate.
[0065] like Figure 5As shown, the waist length adjustment mechanism 14 includes a waist middle section 14-1, a waist length adjustment slider 14-2, a compression spring 14-3 and a length adjustment button 14-4. The length adjustment button 14-4 and the compression spring 14-3 are used to adjust the length. When the length needs to be adjusted, only the lower end protrusions of the length adjustment buttons 14-4 on both sides are pressed, and the compression spring 14-3 between the lower end protrusions of the buttons and the waist middle section 14-1 is compressed, and the length adjustment button 14-4 will rotate with the rotating shaft as the rotation center, so that the upper end of the button will expand outwards and disengage from the length adjustment slider 14-2 slot, and the length adjustment slider 14-2 originally stuck by the button will be able to move left and right, and the waist length can be quickly adjusted at this time, so that the waist width can be adjusted.

The upper end of the waist-hip connecting piece 13-1 is connected to the waist, and the lower end is connected to the flexion internal rotation middle piece 13-2 through the flexion part shaft sleeve 13-3. The upper end of the flexion internal rotation middle piece 13-2 is connected to the waist-hip connecting piece 13-1 through the flexion part shaft sleeve 13-3, and the lower end is dug with a groove for placing the shaft sleeve and the upper end of the internal rotation and abduction middle piece 13-8 screwed in, and is fixed to the internal rotation clamping piece through screws. The deformation realizes the clamping of the sleeve. The outer ring of the flexion sleeve 13-3 cooperates with the waist-hip connection 13-1 and the flexion internal rotation intermediate piece 13-2. The flexion sleeve cover 13-4 is installed on each side of the waist-hip connection 13-1, and is connected to the waist-hip connection 13-1 by screws. The function of this component is to prevent the flexion sleeve 13-3 from axial movement and falling off. The upper end of the internal rotation screw 13-5 is stuck in the groove of the flexion internal rotation intermediate piece 13-2, and the lower end is screwed into the upper end of the internal rotation and abduction intermediate piece 13-8. . The outer side of the internal rotation sleeve 13-7 cooperates with the stepped hole of the flexion and internal rotation middle piece 13-2, and the inner side cooperates with the outer diameter of the upper end of the internal rotation and abduction middle piece 13-8. The internal rotation clamping piece 13-6 is fixedly connected and deformed with the flexion and internal rotation middle piece 13-2 by screws to achieve the clamping of the sleeve. The upper end of the internal rotation and abduction middle piece 13-8 cooperates with the inner diameter of the sleeve, and the lower end is connected to the upper thigh rod 4-1 through a pin shaft.

[0067] like Figure 7As shown, the thigh mechanism includes an upper thigh rod 4-1, a thigh fixing binding mechanism 4-2, and a lower thigh rod 4-3. The upper part of the lower thigh rod 4-3 is provided with a plurality of circular holes in the length direction, and the lower part of the upper thigh rod 4-1 is provided with elastic clips, which connect the upper and lower thigh tubes with different circular holes through the clips to achieve the adjustable thigh length.
[0068] like Figure 8 As shown, the knee joint mechanism includes a motor fixed end 5-1, a knee joint drive motor 5-3, and a torque sensor 8; the knee joint drive motor 5 is installed on the motor fixed end 5-1 by screws, the motor rotating part is connected to the torque sensor 8, the knee joint drive motor 5 and the motor fixed end 5-1 are connected with the torque sensor 8 by bolts, the upper end of the motor fixed end 5-1 is connected to the lower thigh rod 4-3 by a pin, and the torque sensor 8 is connected to the upper calf rod 6-1 by screws.

The binding body is connected to the calf protection device 1-5 by a magnetic buckle, and the calf protection device 1-5 is fixed to the exoskeleton. The calf is bound by the calf protection device 1-5 to achieve wearing and fixing on the calf. The magnetic buckle connector is connected to the lower calf rod through the protrusion on the magnetic buckle connector, and can move up and down.
[0070] like Fig.10 As shown, the foot-end wearable component includes a lower calf rod 6-3, a foot-shoe connector 7-1, a leg base 7-2 and a vibration sensor 7-3; a vibration sensor is arranged next to the foot-shoe for data collection. The foot-shoe connector is connected to the calf connecting rod aluminum alloy bracket and the vibration sensor fixing part by screws, and there is a strap connected by rivets on the foot-shoe connector, and the other end of the strap is connected to the foot-shoe by rivets.
[0071] When the user is carrying a heavy load and encounters an emergency such as falling, bending over to avoid, or picking up dropped objects, it is difficult to stand up due to the heavy load. At this time, the encoder in the back drive motor in the back assist mechanism detects the angle change and transmits the angle change information to the control box. The program in the control box determines whether assistance is needed. If it meets the assistance conditions, the motor will receive a start signal, and the motor drives the back connecting rod to provide assistance for the human body from bending over to standing upright.
[0072] The user wears the modular mecha compatible with this power assist, and fixes the protective wear to the body through the magnetic buckle. At the same time, the protective device provides the binding function required by the wearable exoskeleton. The protective load and other loads are supported by the whole body exoskeleton structure. When the user is in a state of walking, climbing, etc., the drive motor at the knee joint of the lower limb exoskeleton works to provide assistance to the user. When the user falls due to the load, bends down to avoid, or picks up objects, it is difficult to get up due to the heavy load, and the back drive motor works to help the user get up.
