Description

Technical Field

[0001] The present invention relates to exoskeleton technology, in particular to a wearable exoskeleton. Background Art

[0002] Exoskeletons are an important branch of the robotics field. Wearable exoskeletons can assist the wearer in completing complex and heavy movements, or enhance the wearer's athletic ability. Exoskeletons are mostly designed for walking on flat roads, taking into account going up and down stairs and crossing obstacles. Generally, exoskeletons are mostly used in a flat road environment and up and down slopes during normal use. Therefore, simulating normal human walking on a flat road is not the most energy-saving way of movement. In addition, due to the large number of degrees of freedom of the exoskeleton during walking, there are deviations in the coordination between the joints, and the walking speed cannot be comparable to that of a normal person during movement. Improper use may even cause muscle strain to the wearer.

[0003] In order to increase walking speed, traditional exoskeletons use wheels on the soles of each foot to drive walking. However, when driving on a flat road, the exoskeleton needs to adjust and control the posture of both feet at the same time to maintain balance and turn, which makes the control relatively complicated. Summary of the invention

[0004] Based on this, it is necessary to provide a wearable exoskeleton that can not only effectively improve walking speed but also make the control process simple and easy to implement.

[0005] The technical solution is as follows:

At the same time, the internal rotation limit structure performs limit adjustment according to the wearer's joints, and converts the instructions into commands through the wearer's body posture to control the unicycle to move forward or backward. When the wearer needs to go up stairs or cross uneven roads, the unicycle can be removed, and the unicycle can be flexibly used in conjunction with the exoskeleton structure to speed up the travel speed. Moreover, since the balance control of the unicycle is used to make the parallel movement of both feet equivalent to the movement of a single point, the control process is simple and easy to implement.

[0038] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the present invention, so the present invention is not limited by the specific embodiments disclosed below.

[0039] Reference Figure 1 , 2An embodiment of the present application provides a wearable exoskeleton, including a calf support 10, a right calf support 20, a left foot piece 30, a right foot piece 40, a left ankle joint motor module 50, a right ankle joint motor module 60 and a unicycle 70. The left foot piece 30 and the right foot piece 40 are used to place the left and right soles of the wearer, respectively. The left ankle joint motor module 50 and the right ankle joint motor module 60 are both provided with an absolute encoder, a torque sensor and a rotation limit structure. The left ankle joint motor module 50 is used to connect the left calf support 10 and the left foot piece 30, and the right ankle joint motor module 60 is used to connect the right calf support 20 and the right foot piece 40. Pedals for placing the left foot piece 30 and the right foot piece 40 are respectively provided on both sides of the unicycle 70, which are used to drive the wearable exoskeleton to move.

[0040] When the wearable exoskeleton of the present embodiment is used, the wearer puts both feet into the left foot piece 30 and the right foot piece 40 respectively, and the left ankle joint motor module 50 and the right ankle joint motor module 60 move in a rotational manner to assist the movement of the wearer's foot when the sole is lifted. The left foot piece 30 and the right foot piece 40 are placed on the pedals of the unicycle piece 70 respectively, and the position data of the wearable exoskeleton movement is obtained in real time according to the absolute value encoder and torque sensor inside. At the same time, the internal rotation limit structure performs limit adjustment according to the wearer's joints, and converts the instructions into commands through the wearer's body posture to control the unicycle piece 70 to move forward or backward. When the wearer needs to go up stairs or cross uneven roads, the unicycle piece 70 can be removed, and the unicycle piece 70 can be flexibly used in conjunction with the exoskeleton structure to speed up the travel speed. Moreover, since the balance control of the unicycle piece 70 is used to make the parallel movement of both feet equivalent to the movement of a single point, the control process is simple and easy to implement.

[0041] Among them, the left ankle joint motor module 50 and the right ankle joint motor module 60 can adopt the ankle joint control principle in the existing exoskeleton, obtain motion data through their built-in absolute encoder and torque sensor, and the rotation limit structure keeps the calf support 10, the right calf support 20, the left foot member 30 or the right foot member 40 at a certain rotation position. The rotation limit structure can be a mechanical limit structure or an electronic limit structure. A main control box 150 can be set on the calf support 10, the right calf support 20, the left foot member 30 or the right foot member 40, and the main control box 150 is electrically connected to the left ankle joint motor module 50 and the right ankle joint motor module 60 to obtain data and issue control instructions to control the rotation of the left ankle joint motor module 50 and the right ankle joint motor.

[0042] Specifically, the wheel 70 is detachably connected to the left foot piece 30 and the right foot piece 40. When the road surface is flat, the left foot piece 30 and the right foot piece 40 are connected to the wheel 70, and the whole body moves forward or backward under the drive of the wheel 70 to provide a travel speed. When the road surface is uneven, the left foot piece 30 and the right foot piece 40 are separated from the wheel 70, and no longer move with the help of the wheel 70, but walk through the left foot piece 30 and the right foot piece 40 to flexibly adapt to the changes of different road environments. The wheel 70 can adopt the control principle of the existing unicycle balance car, and control the wheel 70 to move forward or backward according to the changes in the wearer's posture to maintain overall balance. A gyroscope sensor can be set in the main control box 150, and the center of gravity position of each joint can be controlled according to the information obtained by the gyroscope sensor to adjust the balance. Optionally, the wheel 70 is a hub motor module.

[0043] Furthermore, in one embodiment, the wearable exoskeleton also includes a left thigh support 80, a right thigh support 90, a left knee joint motor module 100 and a right knee joint motor module 110. The left knee joint motor module 100 and the right knee joint motor module 110 are both provided with absolute encoders, torque sensors and rotation limit structures. The left knee joint motor module 100 is used to connect the left calf support 10 and the left thigh support 80, and the right knee joint motor module 110 is used to connect the right calf support 20 and the right thigh support 90. The left knee joint motor module 100 and the right knee joint motor module 110 generate auxiliary torque between the left thigh support 80 and the left calf support 10, and the right thigh support 90 and the right calf support 20 to assist the knee joint movement. The left knee joint motor module 100 and the right knee joint motor module 110 move in a rotational manner, and obtain motion data through their built-in absolute encoders and torque sensors. The rotation limit structure keeps the left thigh support 80 and the left calf support 10, and the right thigh support 90 and the right calf support 20 at a certain rotation position. The rotation limit structure can be a mechanical limit structure or an electronic limit structure.

[0044] In this embodiment, the left knee joint motor module 100 and the right knee joint motor module 110 can adopt the knee joint control principle in the existing exoskeleton. A main control box 150 can be set on the left thigh support 80 and the right thigh support 90, or a main control box 150 electrically connected to the left ankle joint motor module 50 and the right ankle joint motor module can be shared. The main control box 150 is electrically connected to the left knee joint motor module 100 and the right knee joint motor module 110 to obtain data and issue control instructions to control the left knee joint motor module 100 and the right knee joint motor module 110 to rotate.

[0045] Specifically, refer to Figure 1 , 2In one embodiment, the wearable exoskeleton further comprises a waist cross bar 120, a left hip joint motor module 130, a right hip joint motor module 140 and a main control box 150, wherein the left hip joint motor module 130 and the right hip joint motor module 140 are both provided with an absolute encoder, a torque sensor and a rotation limit structure. The left hip joint motor module 130 is used to connect the left end of the waist cross bar 120 with the left thigh support 80, and the right hip joint motor module 140 is used to connect the right end of the waist cross bar 120 with the right thigh support 90. The main control box 150 is arranged on the waist cross bar 120, and is provided with a battery, a gyroscope sensor and an acceleration sensor, and is used to control the left ankle joint motor module 50, the right ankle joint motor module 60, the left knee joint motor module 100, the right knee joint motor module 110, the left hip joint motor module 130 and the right hip joint motor module 140 to cooperate with the single wheel 70 to move. The left hip joint motor module 130 and the right hip joint motor module 140 drive the left thigh support 80 and the right thigh support 90 to achieve hip joint assistance. The left hip joint motor module 130 and the right hip joint motor module 140 move in a rotational manner, and the hip joint control principle in the existing exoskeleton can be adopted. The main control box 150 is provided with a battery, a gyroscope sensor and an acceleration sensor, which are used to control the left hip joint motor module 130, the right hip joint motor module 140, the left knee joint motor module 100, the right knee joint motor module 110, the left ankle joint motor module 50, the right ankle joint motor module 60, the wheel 70 and plan gait, and assist the wearer to complete walking, sitting, and going up and down stairs.

[0046] As a walking assistance device, after the wearer puts the exoskeleton on, the exoskeleton converts the wearer's body posture into instructions to control the wheeled member 70 to move forward or backward. At the same time, according to the gyroscope sensor information in the main control box 150, it controls each joint to adjust the center of gravity. The knee joint, hip joint and ankle joint adjust the length of the two feet according to the left and right tilt angle signals returned by the acceleration sensor. If the center of gravity is biased to the right, the bending degree of the left foot is increased and the bending length of the angle is reduced, that is, the left foot is bent and the right foot is straightened to adjust the center of gravity. If the center of gravity is biased to the left, the bending degree of the left and right feet is adjusted in opposite directions. When the wearer needs to go up stairs or cross uneven roads, the hub motor module can be removed.

[0047] Furthermore, the left foot piece 30 and the right foot piece 40 are respectively provided with pressure sensors inside to detect the contact between the sole of the foot and the device and judge the state of the wearer during walking. The pressure sensor senses the pressure of the sole of the foot and cooperates with the torque sensors of each joint to sense the human body's action intention, and plans the left ankle joint motor module 50, the right ankle joint motor module 60, the left knee joint motor module 100, the right knee joint motor module 110, the left hip joint motor module 130 and the right hip joint motor module 140. When a person starts to move, a thrust is generated on the exoskeleton. Each joint motor module can sense this state and execute a pre-set motion curve to follow and support the human body to complete the action. The motion data or motion curve of each joint motor module during walking is pre-set through experiments. According to each person's walking habits, the motion curve is different and is collected through experiments.

[0048] Reference Figure 3 , 4 In another embodiment, the wearable exoskeleton further includes a left hip joint motor module 130, a right hip joint motor module 140, a cushion 160 and a main control box 150. A cushion 160 is provided, and the height of the cushion 160 can be adjusted according to the posture of the wearer to solve the problem of fatigue caused by long-term wearing. Compared with the previous embodiment, the wearable exoskeleton of this embodiment does not have a waist crossbar 120, the top of the left thigh bracket 80 is connected to the top of the right thigh bracket 90, the left hip joint motor module 130 is connected to the top of the left thigh bracket 80, the right hip joint motor module 140 is connected to the top of the right thigh bracket 90, and the cushion 160 is arranged at the top of the left thigh bracket 80 and the right thigh bracket 90. Absolute encoders, torque sensors and rotation limit structures are arranged inside the left hip joint motor module 130 and the right hip joint motor module 140. The cushion 160 is arranged at the top of the left thigh bracket 80 and the right thigh bracket 90 to provide a sitting position for the wearer. The main control box 150 is provided with a battery and a gyro sensor, which are used to control the left ankle joint motor module 50, the right ankle joint motor module 60, the left knee joint motor module 100, the right knee joint motor module 110, the left hip joint motor module 130 and the right hip joint motor module 140 to move in coordination with the wheel 70. The left hip joint motor module 130 and the right hip joint motor module 140 drive the left thigh support 80 and the right thigh support 90 to achieve hip joint assistance, and the left hip joint motor module 130 and the right hip joint motor module 140 move in a rotational manner, and the hip joint control principle in the existing exoskeleton can be adopted. The main control box 150 is provided with a battery and a gyroscope sensor for controlling the left hip joint motor module 130, the right hip joint motor module 140, the left knee joint motor module 100, the right knee joint motor module 110, the left ankle joint motor module 50, the right ankle joint motor module 60, the wheel 70 and planning gait, so as to assist the wearer to complete movements such as walking, sitting, and going up and down stairs.

[0049] In one embodiment, a pressure sensor is provided inside the seat cushion 160 to detect the contact between the wearer's body and the wearable exoskeleton to adjust the height of the seat cushion 160. The wearer can sit directly on the seat cushion 160 and step on the left foot piece 30 and the right foot piece 40. When the exoskeleton senses the pressure, it will start the control function and select forward, backward, acceleration and deceleration according to the wearer's forward and backward leaning. The seat cushion 160 will detect the posture of the passenger. When the passenger presses down hard, the seat cushion 160 will move down. The height of the seat cushion 160 is adjusted by rotating the left knee joint motor module 100 and the right knee joint motor module 110. At the same time, the left ankle joint motor module 50 and the right ankle joint motor module 60 will rotate at the same time to adjust the position of the center of gravity. When the passenger lifts slightly, the seat cushion 160 will move up and close to the wearer's body. When it is necessary to cross uneven roads or go up and down stairs, the hub motor module can be removed and hung on the back. The pressure sensors inside the left foot piece 30 and the right foot piece 40 sense the pressure of the sole of the foot, and cooperate with the torque sensors of each joint to sense the human body's movement intention, and plan the left ankle joint motor module 50, the right ankle joint motor module 60, the left knee joint motor module 100, the right knee joint motor module 110, the left hip joint motor module 130 and the right hip joint motor module 140. When a person starts to move, a thrust is generated on the exoskeleton. Each joint motor module can sense this state and execute a pre-set motion curve to follow and support the human body to complete the action.
