Description

Technical Field

[0001] This utility model relates to the field of assistive walking robot technology, specifically to an intelligent assistive walking exoskeleton robot. Background Technology

[0002] With the rapid development of technology, intelligent walking exoskeleton robots have gradually entered the public eye, bringing new hope to many people with mobility impairments. They integrate cutting-edge technologies from multiple fields such as mechanical engineering, electronic technology, computer science, and biomedical engineering. They are wearable intelligent mechanical devices that can assist or enhance the user's limb movements, helping them to restore or improve their walking ability.

[0003] However, in practical applications, the problems of wearing discomfort and inconvenience in adjustment are significant, which seriously limits their promotion and use. The existing mechanical structure design of exoskeleton robots is mostly based on the average human body size and movement characteristics. The size of traditional exoskeleton robots is difficult to adjust and it is difficult to fit the body curves and sizes of different users. For users who are short or tall, the joint connection parts, leg supports and other components may not be able to fit accurately, resulting in uneven local stress. Wearing them for a long time can easily cause discomfort symptoms such as pain and pressure sores. In addition, the complicated adjustment operation process also increases the threshold of use, requiring the assistance of professionals and reducing the convenience of use. For this reason, we have proposed an intelligent mobility exoskeleton robot. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this invention provides an intelligent walking-assistive exoskeleton robot, which solves the aforementioned problems.

[0006] (II) Technical Solution

[0007] To achieve the above-mentioned objectives, this utility model provides the following technical solution: an intelligent walking-assistive exoskeleton robot, comprising an adjustable waist wearing device, thighs, joints, and lower legs. The adjustable waist wearing device has two axially symmetrically distributed thighs at its bottom. The two thighs are rotatably connected to the sidewall of the adjustable waist wearing device. The bottom of the thighs is provided with a joint, and the bottom of the joint is provided with a lower leg. The top of the lower leg is rotatably connected to the joint.

[0008] Preferably, the adjustable waist wearing device consists of three parts: a back-fitting component, two sets of axially symmetrically distributed side supports, and an adjustment component. The main body of the adjustable waist wearing device is the back-fitting component, the back of which is slidably connected to the opposite axial ends of the two side supports. Each of the two side supports is provided with an adjustment component on the opposite axial end, and the adjustment component is snapped into the back of the back-fitting component.

[0009] Preferably, the back of the backing piece is provided with two axially symmetrically distributed adjustment strips, and the adjustment strips are provided with adjustment locking grooves, which are serrated.

[0010] Preferably, the main body of the side bracket is a curved rod, and the inner side of the curved side bracket is provided with an arc-shaped rubber pad. The side wall of the side bracket is provided with a rotating block, and the rotating block is rotatably connected to the top end of the thigh. The two side brackets have mating cavities inside their opposite side shaft ends, and the mating cavities are slidably connected to the adjustment strip. The side bracket is provided with a hollow assembly block on the side away from the back-attaching piece. The hollow assembly block communicates with the mating cavity, and the adjustment piece is placed inside the hollow assembly block.

[0011] Preferably, the adjusting component consists of two parts: an elastic element and a clamping block. The elastic element is connected to the inside of the hollow assembly block, and the clamping block is sleeved on the outside of the elastic element. The side wall of the clamping block is provided with two pillars that are connected to the adjusting clamping groove.

[0012] Preferably, the lower leg component consists of three parts: a connector, a height adjustment component, and a pedal. The top of the lower leg component is the connector, and the shaft end of the connector is provided with a connecting rotating block that is rotatably connected to the joint component. The shaft end of the connector opposite to the connecting rotating block is provided with a sliding height clamping component.

[0013] (III) Beneficial Effects

[0014] Compared with the prior art, this utility model provides an intelligent walking-assistive exoskeleton robot, which has the following beneficial effects:

[0015] 1. This intelligent walking assistive exoskeleton robot improves wearing comfort and fit. Through an adjustable waist-mounted device, users can freely adjust the width of the two side supports according to their waist circumference. The flexible material of the back support conforms to the curve of the lower back, and the arc-shaped rubber pads on the inner side of the side supports reduce friction on the sides of the lower back, greatly improving wearing comfort. Simultaneously, the height of the lower leg components is adjustable to accommodate people of different heights, ensuring the robot fits closely to the user's body curves. This avoids problems such as pain and pressure sores caused by uneven pressure, making it less likely for users to experience discomfort even after prolonged wear, significantly optimizing the wearing experience.

[0016] 2. This intelligent walking assistive exoskeleton robot simplifies adjustment operations and improves ease of use. The adjustable waist-mounted device features a cleverly designed adjustment mechanism. By pressing the elastic element, the locking block and adjustment slot become disengaged, allowing for easy width adjustment. After adjustment, releasing the elastic element re-locks the device. The operation is simple and easy to understand. The height adjustment of the lower leg components is equally convenient. The sliding height locking element works with the adjustment hole, allowing users to quickly adjust the height themselves without professional assistance. This simple and convenient adjustment method lowers the barrier to entry, enabling users with different needs to easily get started and adjust the robot according to their own circumstances, thus improving the convenience and flexibility of use.

The sliding height locking piece 19 engages with the adjustment hole 21 on the side wall of the height adjustment piece 17, changing the connection position between the height adjustment piece 17 and the connecting piece 16 to accommodate users of different heights. The pedal 22 can rotate at a fixed angle to ensure the feet move freely during walking. In its current state, once the device is worn, when the user intends to move, such as lifting their leg to take a step, the built-in sensor system detects changes in the body's muscle electrical signals and posture, and transmits the data to the control system. After processing the data, the control system sends a command to the power system, which drives the joint component 3 to move. The thigh part 2 and the adjustable waist wearing device 1 are engaged by rotating blocks 8, and the connecting rotating block 18 at the top of the calf component 4 is engaged by rotating blocks 3. Under the action of the power system, all components move in coordination to provide assistance to the user. The side support 6 of the adjustable waist wearing device 1 drives the thigh part 2 to move through rotating blocks 8, enabling the user to walk smoothly with the cooperation of the adjustable waist wearing device 1, thigh part 2, joint component 3, and calf component 4. During the process, each adjustment structure ensures that the robot always fits the user's body, ensuring the accuracy and comfort of the assistance.
