[0002] A wheelchair is a chair equipped with wheels that can assist with walking. It's an important means of transportation for the injured, sick, and disabled for home rehabilitation, transportation, medical appointments, and outings. It not only provides mobility for people with physical disabilities and limited mobility, but more importantly, it facilitates family members' mobility and care for patients, allowing them to exercise and participate in social activities. For patients with non-lower limb amputations, to increase riding comfort, left and right footrests are installed on the front of the wheelchair, preventing their feet from becoming suspended in the air. Patients who require wheelchairs are generally frail, especially those with leg injuries or paralysis, who are unable to control their feet. When a patient is transferred from a bed or a stool to a wheelchair, the patient has to move forward and then backward before sitting on the wheelchair due to the presence of the footrest and footrest bracket. This action is very difficult for patients with mobility problems. Therefore, a foldable footrest is currently provided to overcome this problem. However, the existing foldable footrest is placed on the inside of the wheelchair, which makes it easy for the patient to collide with the legs of the patient during daily use. At the same time, foreign objects on the footrest may easily stick to the pants of the patient. Utility Model Content

[0021] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention and are not used to limit the present invention.

[0022] Example: Figure 1-5 As shown, the utility model is a foldable connecting rod footrest mechanism, comprising a connecting frame 2 connected to a wheelchair frame 1, and a sleeve 3 rotating along the connecting frame 2 is provided at the bottom end of the connecting frame 2, and a supporting block 4 for supporting the sleeve 3 is provided at the bottom of the connecting frame 2, and a rubber damping layer 5 is provided between the inside of the sleeve 3 and the connecting frame 2;

[0023] An articulated seat 6 is provided on the outside of the sleeve 3, and a flip-up footrest 7 is provided on the articulated seat 6, and a support plate 8 for supporting the bottom of the footrest 7 is provided on the articulated seat 6; a functional handle 9 for manually driving the sleeve to rotate is provided on the outside of the sleeve 3; when the footrest 7 is not in use, the sleeve 3 is rotated to flip the folded footrest 7 to both sides of the wheelchair frame. The bottom end of the connecting frame 2 is provided with a sleeve 3 that rotates along the connecting frame 2, and an articulated seat 6 is provided on the outside of the sleeve 3, and a flip-up footrest 7 is provided on the articulated seat 6, and a support plate 8 for supporting the bottom of the footrest 7 is provided on the articulated seat 6; in this way, the footrest can be folded without affecting the use of other functions. When the footrest 7 is not in use, the sleeve 3 is rotated to flip the folded footrest 7 to both sides of the wheelchair frame, which can free up space and avoid the collision between the folded and stored footrest and the human body's legs, which is not conducive to local movement of the legs, and foreign objects on the footrest will easily stick to the pants of the disabled person. A rubber damping layer 5 is provided between the inside of the sleeve 3 and the connecting frame 2, so that in the absence of a certain external force, no rotation will occur between the sleeve and the connecting frame, thereby avoiding the sleeve from rotating.

[0024] The sleeve is provided with a fixing mechanism for fixing the folded footrest 7 .

[0025] The fixing mechanism includes a positioning seat arranged inside the sleeve 3, and a first magnetic block 11 is provided on the positioning seat, and a second magnetic block 12 is provided on the pedal 7, which is magnetically attracted to the first magnetic block 11. The pedal is fixed by the magnetic attraction between the first magnetic block 11 and the second magnetic block 12 to prevent the pedal from being opened. The pedal is fixed by a magnetic fixing method, which makes it convenient to unfold and fold the pedal for storage, and is convenient for operation.

When the footrest 7 is not in use, the sleeve 3 is rotated to flip the folded footrest 7 to both sides of the wheelchair frame, which frees up space and avoids the collision between the folded footrest and the legs of the human body, which is not conducive to leg movement. Due to local movement of the footrest, foreign objects on the footrest will easily stick to the pants of the person with mobility difficulties. A rubber damping layer 5 is provided between the inside of the sleeve 3 and the connecting frame 2, so that without a certain external force, the sleeve and the connecting frame will not rotate, thereby preventing the sleeve from rotating. The footrest is fixed by the magnetic attraction of the first magnetic block 11 and the second magnetic block 12, preventing the footrest from opening. The footrest is fixed by a magnetic fixing method, which makes it convenient to unfold and fold the footrest for easy operation.
