[0028] Auxiliary standing assembly includes electric push rod 12, electric push rod 12 is fixedly connected in the inside of two installation shell 9, two electric push rod 12 output ends are fixedly connected with rack plate 13, rotating rod 10 outside both sides are fixedly connected with gear 11, two gear 11 are engaged with two rack plate 13, two rack plate 13 lower parts are fixedly connected with sliding block 14, two installation shell 9 are equipped with sliding slot 15 inside, two sliding blocks 14 are slidably connected in the inside of two sliding slots 15, the movement of sliding block 14 is facilitated by being equipped with sliding slot 15.
[0029] Specifically, when the patient needs to stand up, first, place both hands on the upper part of the handle 20 in front of the wheelchair to maintain balance and obtain additional support, then the patient can start the two electric push rods 12, after starting, the electric push rods 12 drive the two rack plates 13 fixed at the output end to contract synchronously, with the contraction of the rack plates 13, the two upper meshing gears 11 are driven to rotate, the rotation of the gears 11 further drives the middle fixed rotating rod 10 to rotate smoothly in the middle of the wheelchair frame 1, during the rotation of the rotating rod 10, the externally fixed seat cushion 5 begins to gradually turn upward inside the frame 1, as the seat cushion 5 turns upward, the support force below the seat cushion 5 gradually lifts the patient's hips upward, helping the patient to slowly and smoothly transition to a standing position, through this design of the seat cushion 5 turning, the patient can complete standing up without relying on the help of caregivers or family members, this function greatly improves the patient's independence, enabling them to operate the wheelchair independently when they need to stand up, meeting the needs of daily activities, in addition, this design significantly reduces the patient's dependence on others while significantly reducing the burden on caregivers.
[0030] With reference to Figure 2 , Figure 4 and Figure 6 , the adjusting assembly includes a mounting ring 21 fixedly connected to the outside of the fixed column 17, a rotating plate 22 is rotatably connected inside the mounting ring 21, a crossbar 23 is fixedly connected to the outside right side of the rotating plate 22, which facilitates the use of the operator, a spring 26 is connected to the outside left side of the rotating plate 22, the bottom of the spring 26 is fixedly connected to the outside of the fixed column 17, a plug rod 24 is fixedly connected to the upper left side of the rotating plate 22, a through hole 25 is formed in the inside of the fixed column 17, the plug rod 24 is slidingly connected inside the through hole 25, the through hole 25 facilitates the movement of the plug rod 24, plug holes 18 are formed on both sides of the outside of the adjusting rod 19, the plug rod 24 is inserted into the plug holes 18, improving the stability of the adjusting rod 19 after adjustment.
[0031] Specifically, when the height of the handle 20 needs to be adjusted, first, by pulling the crossbar 23, the movement of the crossbar 23 drives the rotation of the rotating plate 22 fixed at the bottom inside the mounting ring 21. During the rotation of the rotating plate 22, the spring 26 fixed on the left side outside the rotating plate 22 is stretched, and the spring 26 deforms due to stretching, simultaneously driving the synchronous movement of the insertion rod 24 fixed on the left side of the upper part of the rotating plate 22, so that the insertion rod 24 gradually separates from the inside of the insertion hole 18. When the insertion rod 24 completely separates from the inside of the insertion hole 18, the adjustment rod 19 can be easily lifted upward at this time, and the adjustment rod 19 slides up and down inside the fixed column 17, driving the handle 20 fixed on the upper part to move together. When the handle 20 moves to the appropriate position (adjusted according to the height and body type of the patient), the insertion hole 18 outside the adjustment rod 19 will be aligned with the through hole 25 outside the fixed column 17. When the insertion hole 18 is aligned with the through hole 25, release the crossbar 23, and under the action of the spring 26, the insertion rod 24 will automatically rebound and reinsert into the inside of the insertion hole 18, thereby firmly fixing the adjustment rod 19 at the new position. This design ensures that the height of the handle 20 is locked, providing reliable stability and preventing loosening or displacement during use. This convenient adjustment structure realizes the rapid adjustment of the height of the handle 20, allowing the handle 20 to be adjusted according to the height of different patients. Patients can easily find the holding position that meets their needs when standing, thereby obtaining better support and stability. This design not only improves the practicality of the handle 20, but also ensures the safety of the patient during operation, meeting the diverse needs of use.
[0032] Working principle: When the patient needs to stand, first, place the hand on the upper part of the handle 20 to maintain balance, then start the two electric push rods 12, the two electric push rods 12 retract with the two rack plates 13 fixed on the output end, the two rack plates 13 retract with the two gears 11 engaged on the upper part, the two gears 11 rotate with the rotating rod 10 fixed in the middle part of the frame 1, and the rotating rod 10 rotates with the seat cushion 5 fixed on the outside of the frame 1 and turns up inside the frame 1. When the seat cushion 5 moves, it pushes the patient's hips up, thereby assisting the patient to stand, realizing the assistance of the patient standing through the turning of the seat cushion 5, without the need for the help of nursing staff or family members, improving the patient's autonomy and reducing the burden of nursing;
[0033] When the height of the handle 20 needs to be adjusted, the crossbar 23 is pulled, the crossbar 23 moves with the bottom-fixed rotating plate 22 rotating inside the mounting ring 21, the spring 26 fixed outside and on the left is stretched when the rotating plate 22 rotates, the spring 26 is deformed under force and simultaneously moves with the plug rod 24 fixed on the upper left of the rotating plate 22, the plug rod 24 is separated from the inside of the insertion hole 18, the adjusting rod 19 can be lifted upwards, the adjusting rod 19 moves inside the fixed column 17 and simultaneously moves with the handle 20 fixed on the upper, when the handle 20 moves to the appropriate position, the insertion hole 18 opened outside the adjusting rod 19 is aligned with the through hole 25 opened outside the fixed column 17, then the crossbar 23 is loosened, the plug rod 24 is inserted into the inside of the insertion hole 18 under the counterforce of the spring 26, the height of the handle 20 is conveniently adjusted, the height of the handle 20 can be adjusted according to the height and body shape of the patient, the patient can find the appropriate holding position when standing, thereby providing better support and stability.
[0034] Finally, it should be noted that: the above only for the preferred embodiments of the present application, and not for limiting the present application, although the present application has been described in detail with reference to the foregoing embodiments, for those skilled in the art, it still can be modified, or part of the technical features of the equivalent replacement, within the spirit and principles of the present application, any modification, equivalent replacement, improvement, etc., should be included in the scope of protection of the present application.
