[0036] In this embodiment, the limit member 68 includes an embedded rod 681 and a connecting spring 682. The left end of the embedded rod 681 is elastically connected to the movable rod 62 by the connecting spring 682. The left end of the connecting spring 682 is fixed to the movable rod 62. The embedded rod 681 is clamped with the support frame 66 to fix the support frame 66 inside the movable rod 62, thereby improving the stability of the support frame 66 and preventing it from sliding freely inside the movable rod 62. The servo motor 610 is an ordinary servo motor, which is a power device that can achieve precise adjustment of position, speed or torque through a closed-loop control system.

[0037] In this embodiment, a groove is provided at the front end of the movable rod 62, and the support frame 66 is embedded in the groove, so that the support frame 66 is completely embedded, so that the exposed length of the rear end of the support frame 66 is longer than when it is not embedded, which is beneficial for supporting the patient's armpits, and the patient is lifted up by the rotation of the movable rod 62 and the support frame 66, which is convenient for the patient to go to the toilet and clean up after defecation.

[0038] In this embodiment, a "U"-shaped groove is provided at the rear end of the connecting seat 63, so that after the support assembly 6 is rotated, the connecting seat 63 wraps the support shaft 54 ​​inside, and uses a threaded limiting rod 65 to connect the support shaft 54, thereby achieving stable installation of the support assembly 6 at the front end of the wheelchair.

[0039] In this embodiment, the support assembly 6 is rotated forward so that the connecting seat 63 contacts the support shaft 54 ​​at the right end, and the threaded limit rod 65 is threadedly embedded in the threaded hole 55 at the front end of the support shaft 54, so that the support assembly 6 is stably installed at the front end of the wheelchair. Then, the support frame 1 66 is moved backward and completely embedded in the movable rod 62, and the limit piece 68 is used to achieve the clamping connection, so that the support frame 1 66 is fixed, and the patient's posture is adjusted so that the support frame 1 66 is located under the patient's armpit to support the patient. Then, the servo motor 610 drives the auxiliary frame 611 and the movable rod 62 to rotate forward, thereby causing the support frame 1 66 to drive the patient to lift up, so that the patient leaves the right seat board 7 and the left seat board 10, which is convenient for the patient to take off and put on pants and clean up after defecation.

[0040] Please refer to Figure 5 This embodiment provides a multifunctional wheelchair, wherein the limiting member 68 includes an embedded rod 681 and a connecting spring 682.

The left end of the connecting spring 682 is fixed to the movable rod 62, and the embedded rod 681 is clamped with the support frame 66.

[0041] In this embodiment, the cross-section of the embedded rod 681 is "L"-shaped, and an arc-shaped notch is provided at the top of the right end of the embedded rod 681, which is convenient for pressing the embedded rod 681 inward to make it leave the interior of the support frame 66, thereby releasing the connection between the limit member 69 and the support frame 66, so that the support frame 66 can slide and adjust.

[0042] Please refer to Figure 6-Figure 7 This embodiment provides a multifunctional wheelchair. The adjustment component 5 includes a mounting seat 51, an electric cylinder 52, a connecting plate 53, a support shaft 54, and a threaded hole 55. The inner side of the rear end of the mounting seat 51 is fixed to the support frame 3. The electric cylinder 52 is installed on the top of the mounting seat 51. The top of the electric cylinder 52 is bolted to the connecting plate 53. The top of the connecting plate 53 is fixed with a support shaft 54.

[0043] In this embodiment, two groups of adjustment components 5 are provided, which are symmetrically distributed on the left and right sides, and the support shaft 54 ​​in the left end adjustment component 5 is rotatably connected to the support seat 61, while the front end of the support shaft 54 ​​in the right end adjustment component 5 is provided with a threaded hole 55, and the threaded hole 55 is internally threaded with a threaded limiting rod 65.

[0044] In this embodiment, the mounting seat 51 is inclined outward, and the outward inclined slope of the mounting seat 51 is fixed to the support frame 3, which facilitates the rotation of the support assembly 6 and ensures that there is no interference between the support assembly 6 and other parts of the wheelchair, so that the support assembly 6 can be rotated backward and placed on the side of the left seat plate 7, thereby reducing the volume of the wheelchair and facilitating use.

[0045] In this embodiment, the electric cylinder 52 drives the support shaft 54 ​​upward, thereby driving the support assembly 6 to rise until it meets the patient's height, allowing the support assembly 6 to support the patient's armpits. The patient is then lifted with the help of the support assembly 6. When the support assembly 6 is raised, the outward-angled installation angle of the mounting base 51 prevents the support assembly 6 from contacting the buckle 12 during its rise. The electric cylinder 52 is a conventional electric cylinder, an integrated linear motion actuator that integrates a servo motor and a lead screw. It achieves precise displacement, speed, and thrust adjustment through closed-loop control (with a repeatable positioning accuracy of ±0.01mm38). Its working principle is as follows: the servo motor drives the lead screw to rotate, and the nut converts the rotational motion into linear motion, which is combined with the encoder's real-time feedback to form a closed-loop control.

[0046] Please refer to Figure 9-10 The locking rod 92 is fixed to the top of the connecting block 96, and the locking rod 92 passes through the middle of the return spring 95, the bottom of the return spring 95 is fixed to the connecting block 96, and the top of the return spring 95 is fixed to the locking seat 2 93.

[0047] The present invention provides a multifunctional wheelchair through improvement, and its working principle is as follows:

[0048] By releasing the lock device 9, pushing the lever 94 upward, the lever 94 drives the locking rod 92 to slide upward, and the connecting block 96 presses the return spring 95 to produce deformation and contraction, so that the front end of the locking rod 92 contacts the interlocking state with the locking seat 1 91, and then the left seat plate 10 and the right seat plate 7 are rotated outward, and then the embedded rod 681 is pressed inward, so that the embedded rod 681 leaves the limit opening 67 at the rear end of the support frame 1 66, and then the support frame 1 66 is slid backward until it is completely embedded in the front end of the movable rod 62. At this time, the limit opening 67 at the front end of the support frame 1 66 and the embedded rod 681 are at the same horizontal line. Under the elastic restoring force of the connecting spring 682, the embedded rod 681 moves and cuts into the limit opening 67. At this time, the limit piece 68 and the support frame 1 66 form a card connection, and then;

[0049] The patient's upper body posture is adjusted so that the support frame 66 is placed under the patient's armpit. When the height of the support frame 66 is too low, the electric cylinder 52 pushes the connecting plate 53, the support shaft 54, and the support assembly 6 to move up until the support frame 66 is against the patient's armpit, and then the servo motor 610 is energized to work, driving the movable rod 62 to rotate to the rear end, so that the auxiliary frame 611 and the movable rod 62 rotate forward, thereby lifting the support frame 66 and lifting the patient. Then, the left seat plate 10 and the right seat plate 7 are rotated inward and stably connected with the help of the locker 9. Then, the support frame 66 can be rotated in the opposite direction, so that the patient slowly sits down and the support frame 66 is completely reset to realize the transfer of the patient from the bed to the wheelchair. Among them, the toilet opening 8 is provided to facilitate the patient to use the wheelchair directly to the toilet. The patient is lifted up by the support frame 66, which can realize the transfer, undressing, wearing pants and cleaning after defecation of the patient.

[0050] When the wheelchair moves, the patient is protected by the horizontal support assembly 6 to prevent the patient from leaning forward;

[0051] When the patient needs to perform rehabilitation training or other independent activities, such as eating, brushing teeth, etc., the support assembly 6 at the front end can be folded up, and the threaded limit rod 65 can be outwardly screwed to separate the threaded limit rod 65 from the support shaft 54, and then the support assembly 6 can be moved to the side end of the left seat plate 10, so that the front end of the wheelchair is no longer blocked and the patient can leave the wheelchair from the front end for rehabilitation training.

[0052] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and substitutions can be made without departing from the technical principles of the present invention. These improvements and substitutions should also be regarded as the scope of protection of the present invention.
