[0055] The present invention is further described in detail below in conjunction with the accompanying drawings. It is necessary to point out here that the following specific implementation methods are only used to further illustrate the present invention and cannot be understood as limiting the scope of protection of the present invention. Those skilled in the art can make some non-essential improvements and adjustments to the present invention based on the above application content.

[0056] Example:

[0057] like Figure 1 、 2 As shown, the present invention provides an auxiliary exercise device for patients with myasthenia gravis to stand up, including a base 101, with multiple groups of arc-shaped support legs 103 evenly distributed in a circumferential direction around the base 101, a telescopic rod 201 and a support frame 106 are provided on the base 101, the telescopic rod 201 is provided with a backrest 204 connected by a connecting frame 203, the backrest 204 is provided with an armrest 205, and a seat cushion 301 is hinged to the support frame 106, and the ends of the multiple groups of support legs 103 are all provided with a mounting frame 504 that can be raised and lowered and rotated, and the mounting frame 504 is provided with a rotatable roller 506.

[0058] When using the device, the patient sits on the cushion 301, supported by the backrest 204. The mounting frame 504 at the bottom of the device rotates to facilitate the patient's free movement via rollers 506, assisting with daily life and improving their quality of life. The armrests 205 are also provided with concave surfaces for supporting the armpits. By controlling the telescopic rod 201 to rise, the backrest 204 and armrests 205 together support the patient's upper body. The concave surfaces prevent the patient's armpits from coming off the armrests 205, allowing the patient to perform walking training.

[0059] like Figure 1 、 2 As shown, in this embodiment, the seat cushion 301 is connected to the telescopic rod 201 through a flipping mechanism to convert the extension and contraction of the telescopic rod 201 into driving the seat cushion 301 to flip. The flipping mechanism includes a guide frame 302 arranged at the bottom of the seat cushion 301, the support frame 106 is hinged to the end of the guide frame 302, and a receiving column 202 is provided on the telescopic rod 201, and the receiving column 202 is slidably clamped in the guide frame 302.

[0060] In the initial state, the seat cushion 301 is stably supported by the cooperation of the support frame 106 and the receiving column 202. During the extension process of the telescopic rod 201, the receiving column 202 is driven to slide in the guide frame 302, thereby driving the seat cushion 301 to flip over, so as to lift the patient's buttocks upward, and cooperate with the telescopic rod 201 to drive the armrest 205 to rise to assist the patient to stand up, thereby reducing the force required by the patient to stand up. At the same time, the outer side of the seat cushion 301 is also folded downward so that the armrest 205 can provide stable support for the patient's armpits.

[0061] like Figure 1 、 2 As shown in Figures 5 and 6, in this embodiment, the mounting frame 504 is connected to the telescopic rod 201 through a driving mechanism to convert the extension and retraction of the telescopic rod 201 into driving the mounting frame 504 to rise and fall. The driving mechanism includes multiple sets of transmission frames 401, and the multiple sets of transmission frames 401 can be respectively arranged in multiple sets of support legs 103 for transverse sliding. A propulsion seat 404 is arranged on the base 101 which can be raised and lowered. The propulsion seat 404 is connected to the seat cushion 301 through a propulsion assembly, and the flipping of the seat cushion 301 is converted into driving the propulsion seat 404 to rise and fall through the propulsion assembly. The propulsion assembly includes a propulsion rod 303, one end of the propulsion rod 303 is hinged to the end of the guide frame 302, and the hinge point of the support frame 106 on the guide frame 302 is between the hinge point of the propulsion rod 303 on the guide frame 302 and the receiving column 202, and the other end of the propulsion rod 303 is hinged to the propulsion seat 404.

[0062] In the process of controlling the extension of the telescopic rod 201 to drive the seat cushion 301 to flip, one end of the seat cushion 301 moves downward, thereby pushing the propulsion seat 404 to slide downward through the propulsion rod 303, and a first driving assembly connected to multiple groups of transmission frames 401 is provided on the propulsion seat 404. The first driving assembly converts the lifting of the propulsion seat 404 into driving the transmission frame 401 to slide. The first driving assembly includes first driving columns 405 evenly distributed around the propulsion seat 404, and a first inclined rail 402 is provided at the end of the transmission frame 401. The first driving column 405 is slidably clamped in the first inclined rail 402.

[0063] In the process of pushing the seat 404 downward, it drives multiple groups of first driving columns 405 to move downward, and then the transmission frame 401 can be driven to slide horizontally through the cooperation of the first driving columns 405 and the first inclined rails 402, and multiple groups of positioning frames 102 are evenly distributed on the circumference of the base 101. The multiple groups of transmission frames 401 are respectively slidably set in the multiple groups of positioning frames 102, and the movement of the transmission frames 401 is positioned by the positioning frames 102, so that the multiple groups of transmission frames 401 can be stably controlled to slide in the direction away from the base 101 during the extension of the telescopic rod 201.

[0064] like Figure 7 As shown, in this embodiment, the ends of multiple groups of support legs 103 are all provided with mounting posts 501, which can be raised and lowered. A connecting sleeve 503 is provided on the mounting frame 504. The connecting sleeve 503 is rotatably provided at the bottom of the mounting post 501. The transmission frame 401 is provided with a second drive assembly connected to the mounting post 501. The second drive assembly converts the sliding movement of the transmission frame 401 into driving the mounting post 501 to rise and fall. The second drive assembly includes a second drive post 403 provided on the transmission frame 401 at an end away from the first inclined rail 402. The second inclined rail 502 is provided on the mounting post 501. The second drive post 403 is slidably engaged within the second inclined rail 502. The inclination direction of the second inclined rail 502 is opposite to that of the first inclined rail 402.

[0065] In the initial state, the connecting sleeve 503 can rotate at the bottom of the mounting column 501 so that the mounting frame 504 can rotate freely, thereby allowing the roller 506 to roll freely on the plane, making it convenient for the patient to move in all directions. During the sliding process of the transmission frame 401, the cooperation between the second driving column 403 and the second inclined rail 502 can drive the mounting column 501 to rise, thereby driving the mounting frame 504 and the roller 506 to rise.

[0066] like Figure 3 、 4As shown in Figures 5 and 7, in this embodiment, a locking mechanism is provided on the support leg 103, which locks the rotation of the roller 506 in one direction after the mounting frame 504 is raised. The locking mechanism includes a lifting frame 601 that is escalable and disposed at the end of the support leg 103. A pawl 602 is provided at the bottom of the lifting frame 601. A ratchet 507 is provided on the roller 506. When the mounting frame 504 is raised, the ratchet 507 can engage with the pawl 602. An elastic member 603 is provided between the lifting frame 601 and the inner wall of the support leg 103. The support leg 103 is provided with a guide assembly connected to the mounting frame 504. The guide assembly drives the multiple groups of mounting frames 504 to rotate in the same direction after the mounting frame 504 is raised. The guide assembly includes a guide tube 104 arranged at the bottom of multiple groups of support legs 103. The end of the guide tube 104 is a slope, and a fixing groove 105 is provided at the top of the slope. The multiple groups of fixing grooves 105 are oriented in the same direction. A guide column 505 is provided on the mounting frame 504. During the rising process of the mounting frame 504, the guide column 505 can abut against the slope of the guide tube 104.

[0067] During the rising process of the mounting frame 504, the guide column 505 is driven to slide along the inclined surface of the guide cylinder 104 through the contact between the guide column 505 and the inclined surface of the guide cylinder 104, so that the mounting frame 504 rotates along the axis of the mounting column 501 until the guide column 505 is stuck in the fixing groove 105, completing the position fixation of the mounting frame 504 and making the directions of multiple groups of rollers 506 the same, and at the same time making the pawl 602 stuck on the ratchet 507, and the movement of the roller 506 is locked in one direction through the cooperation of the elastic member 603, the pawl 602 and the ratchet 507. When the patient falls backward due to physical exhaustion, the rotation of the roller 506 is automatically locked by the above structure to prevent the entire device from sliding on the ground, so as to stably support the patient and prevent the patient from falling.

[0068] Specific usage and beneficial effects of the present invention:

[0069] When the device is in use, the patient can sit on the seat cushion 301, and the roller 506 can be used to move the device on the ground to assist the patient in walking. When the patient needs to stand up, the telescopic rod 201 can be controlled to extend to drive the seat cushion 301 to flip over, and at the same time, the backrest 204 and the armrest 205 above it can be raised to support the patient's armpits, thereby assisting the patient in standing up and walking exercises. The patient can also place the armrest 205 under the armpit while walking to drive the entire device to move on the ground, thereby supporting the patient's body and reducing the force required by the patient during walking. In the process of extending and retracting the telescopic rod 201, the mounting frame 504 is raised and lowered through the driving mechanism. When the mounting frame 504 rises, the rotation of the multiple sets of rollers 506 can be locked in one direction through the locking mechanism, so that the multiple sets of rollers 506 can only roll forward. If the patient falls backward due to insufficient physical strength or muscle strength, the locking of the rollers 506 can effectively prevent the entire device from sliding backward, thereby providing stable support for the patient's body and improving the patient's safety during walking exercise. The overall practicality of the device is strong and worthy of promotion.

[0070] The basic principles, main features, and advantages of the present invention have been shown and described above. It is obvious that the present invention is not limited to the details of the exemplary embodiments described above. Modifications and improvements may be made based on the present invention, as will be apparent to those skilled in the art. Therefore, such modifications and improvements, which do not depart from the spirit of the present invention, are intended to fall within the scope of protection claimed in the present invention.
