[0013] On the other hand, the present invention also provides a method of using an assistive exercise device for frail elderly people according to any of the above claims, comprising the following steps: S1: First, adjust the height of the upper body exercise components and the angle of the backrest according to the elderly person's height. Specifically: First, open the electric actuator. The retraction of the actuator's movable end causes the rectangular frame to move. The movement of the rectangular frame involves two processes: Process 1: Under the action of the compression spring 2, the movable block moves synchronously with the rectangular frame, which in turn drives the strip tooth plate 1 to move, thereby driving the gear 1 to rotate, which in turn drives the long screw to rotate. The rotation of the long screw drives the threaded sleeve 1 to rise and fall, thereby driving the upper body exercise component to rise and fall. The position of the upper body exercise component can be adjusted by controlling the electric push rod. Once the upper body exercise components are adjusted to the appropriate position, the mini electric telescopic rod is activated. The extension of the movable end of the mini electric telescopic rod causes the fixing rod to be inserted into the fixing hole on the first strip toothed plate, thereby fixing the first strip toothed plate. Process 2: As the rectangular frame continues to move, it drives the second toothed plate and the second gear to rotate, which in turn drives the short lead screw to rotate, thereby causing the second threaded sleeve to rise and fall, further driving the bracket and the slider to rise and fall, realizing the rotation of the back plate, thus realizing the angle adjustment of the back plate; S2: Adjust the training intensity. Based on the elderly's exercise needs, rotate the first and second adjustment handles respectively to adjust the training intensity of the upper body exercise component and the lower body exercise component. Similarly, by changing the weight of the load plate on the threaded rod, the training intensity of the auxiliary mechanism can be changed. S3: When the elderly are exercising their upper body, they sit in the box and then grab the rings with both hands. By grabbing the rings, they move the traction rope downwards. The elasticity of the return spring can create resistance to the moving plate, which requires the elderly to exert force. By repeatedly pulling the rings, the elderly can exercise their upper body. S4: When the elderly exercise their lower body, they use their feet to push the board, and the resistance of the board is increased by the action of the spring, so the elderly need to push the board with force to achieve the exercise of the lower body. S5: Secondly, when the elderly need to perform chest expansion exercises, they can hold the handles with both hands and pull the pull rope to rotate the rotating rod. When pulling the pull rope, it overcomes the resistance of the spring and the rotation resistance of the weight plate. When releasing the pull rope, the rotating rod rotates in the direction of the spring under the action of the spring, pulling the arms to extend, thereby exercising the elderly's arm and chest muscle groups. Similarly, the storage box can store the items carried by the elderly, avoiding interference from items such as mobile phones during the exercise.
[0014] Compared with the prior art, the present invention has the following advantages: The use of a drive component allows for easy adjustment of the position of the upper body exercise component, making it suitable for elderly people of different heights and improving the practicality of the auxiliary exercise device. Simultaneously, the angle of the backrest can be adjusted to support the elderly person's back, preventing falls during exercise and providing protection while also benefiting their exercise. The first and second adjustment handles allow for adjustment of the training intensity of the upper and lower body exercise components. A storage box provides storage for the user's belongings. The auxiliary mechanism and limiting pins enable chest expansion exercises, training the user's arm and chest muscles in various ways. Similarly, the intensity of the chest expansion exercise can be adjusted by increasing or decreasing the weight of the weight plates on the threaded rod. Attached Figure Description

[0031] Example 2: Based on Example 1, the present invention provides a method for using an assistive exercise device for elderly and frail individuals, comprising the following steps: S1: First, adjust the height of the upper body exercise component 3 and the angle of the backrest 10 according to the elderly person's height. Specifically: First, open the electric actuator 17. The retraction of the movable end of the electric actuator 17 will move the rectangular frame 24. The movement of the rectangular frame 24 is divided into two processes: Process 1: Under the action of the compression spring 25, the movable block 26 moves synchronously with the rectangular frame 24, which in turn drives the strip tooth plate 21 to move, thereby driving the gear 14 to rotate, which in turn drives the long screw 11 to rotate. The rotation of the long screw 11 drives the threaded sleeve 13 to rise and fall, thereby driving the upper body exercise component 3 to rise and fall. The position of the upper body exercise component 3 can be adjusted by controlling the electric push rod 17. After the upper body exercise component 3 is adjusted to a suitable position, the mini electric telescopic rod 22 is opened. The movable end of the mini electric telescopic rod 22 extends, which drives the fixed rod 27 to be inserted into the fixed hole 28 on the strip toothed plate 21, thereby fixing the strip toothed plate 21. Process 2: As the rectangular frame 24 continues to move, it drives the toothed plate 15 and the gear 16 to rotate, which in turn drives the short lead screw 19 to rotate, thereby causing the threaded sleeve 20 to rise and fall, further driving the bracket 18 and the slider 30 to rise and fall, realizing the rotation of the back plate 10, thereby realizing the angle adjustment of the back plate 10. S2: Adjust the training intensity. Based on the elderly's exercise needs, rotate the first adjustment handle and the second adjustment handle 907 respectively to adjust the training intensity of the upper body exercise component 3 and the lower body exercise component 9. Similarly, by changing the weight of the load plate 334 on the threaded rod 333, the training intensity of the auxiliary mechanism can be changed. S3: When the elderly person is exercising their upper body, they sit in the box 1 and then grab the ring 307 with both hands. By grabbing the ring 307, the traction rope 304 moves downward. The elasticity of the return spring 308 can create resistance to the movable plate 302, which requires the elderly person to exert force. By repeatedly pulling the ring 307, the elderly person can exercise their upper body. S4: When the elderly exercise their lower body, they can use their feet to push the push plate 901. Then, under the action of the compression spring 902, the resistance of the push plate 901 can be increased, so the elderly need to push the push plate 901 with force to achieve the exercise of the elderly's lower body. S5: Secondly, when the elderly need to perform chest expansion exercises, they can hold the handles with both hands and pull the pull rope, which will cause the rotating rod 331305 to rotate. When pulling the pull rope, it overcomes the resistance of the spring 332 and the rotational resistance of the weight plate 334. When the pull rope is released, the rotating rod 331305 rotates in the direction of the spring 332, pulling the arms to unfold, thereby exercising the elderly's arm and chest muscle groups. Similarly, the storage box 31 can store the items carried by the elderly, avoiding interference from items such as mobile phones during the exercise.
[0032] While embodiments of the present invention have been described in detail above, it will be apparent to those skilled in the art that various modifications and variations can be made to these embodiments. However, it should be understood that such modifications and variations fall within the scope and spirit of the invention as defined in the claims. Furthermore, the invention described herein may have other embodiments and can be implemented or carried out in various ways.

10. A method of using an assistive exercise device for frail elderly people according to any one of claims 1-9, characterized in that, The usage steps include the following: S1: First, adjust the height of the upper body exercise component (3) and the angle of the backrest (10) according to the elderly person's height. Specifically: First, open the electric actuator (17). The retraction of the movable end of the electric actuator (17) drives the rectangular frame (24) to move. The movement of the rectangular frame (24) is divided into two processes: Process 1: Under the action of the compression spring 2 (25), the movable block (26) moves synchronously with the rectangular frame (24), which in turn drives the strip tooth plate 1 (21) to move, thereby driving the gear 1 (14) to rotate, further driving the long screw (11) to rotate, and through the rotation of the long screw (11), the threaded sleeve 1 (13) is driven to rise and fall, thereby driving the upper body exercise component (3) to rise and fall. The position of the upper body exercise component (3) can be adjusted by controlling the electric push rod (17). When the upper body exercise component (3) is adjusted to the appropriate position, the mini electric telescopic rod (22) is opened. The movable end of the mini electric telescopic rod (22) extends and drives the fixed rod (27) to be inserted into the fixed hole (28) on the strip toothed plate (21) to fix the strip toothed plate (21). Process 2: As the rectangular frame (24) continues to move, it drives the second strip toothed plate (15) and the second gear (16) to rotate, which in turn drives the short lead screw (19) to rotate, thereby causing the second threaded sleeve (20) to rise and fall, further driving the bracket (18) and the slider (30) to rise and fall, realizing the rotation of the back plate (10), thereby realizing the angle adjustment of the back plate (10); S2: Adjust the training intensity. According to the elderly’s exercise needs, turn the first adjustment handle and the second adjustment handle (907) respectively to adjust the training intensity of the upper body exercise component (3) and the lower body exercise component (9). Similarly, by changing the weight of the load plate (334) on the threaded rod (333), the training intensity of the auxiliary mechanism can be changed. S3: When the elderly are exercising their upper body, they sit in the box (1) and then grab the ring (307) with both hands. By grabbing the ring (307), the traction rope (304) moves downward. The elasticity of the return spring (308) can achieve resistance to the moving plate (302), which requires the elderly to exert force. By repeatedly pulling the ring (307), the elderly can exercise their upper body. S4: When the elderly exercise their lower body, they can use their feet to push the push board (901). Then, under the action of squeezing the spring (902), the resistance of the push board (901) can be increased, so the elderly need to push the push board (901) with force, thereby achieving the exercise of the elderly's lower body. S5: Secondly, when the elderly need to perform chest expansion exercises, they can hold the handles with both hands, pull the traction rope, and drive the rotating rod (331) (305) to rotate. When pulling the traction rope, it overcomes the resistance of the spring (332) and the rotation resistance of the weight plate (334). When the traction rope is released, under the action of the spring (332), the rotating rod (331) (305) rotates in the direction of pulling the arm to unfold, thereby exercising the elderly's arm and chest muscle groups. Similarly, the placement box (31) can store the items carried by the elderly, avoiding interference from items such as mobile phones during the exercise.
