Description
Technical Field
[0001] The utility model relates to the technical field of wheelchairs, and particularly relates to an auxiliary getting-up structure for a wheelchair and a wheelchair with the same. Background Art
[0002] In hospitals, it is very common for patients to move around with the help of wheelchairs. Wheelchairs play an important role in medical rehabilitation and mobility convenience. In a hospital environment, patients often need to undergo various examinations and treatments frequently, and these activities often need to be carried out between different departments. For patients with limited mobility, wheelchairs have become an indispensable auxiliary tool. With the help of wheelchairs, patients can easily move around in the hospital, reducing the troubles and pains caused by limited mobility. In addition, wheelchairs can also be used as part of rehabilitation training. Under the guidance of doctors, patients can exercise moderately through wheelchairs to restore or improve certain functions of the body.
[0003] When a patient gets up with the help of a wheelchair, generally, the feet are first placed on the ground, then the hands hold the armrests of the wheelchair, the back is straightened, and a stable sitting posture is maintained. When getting up, the hands press down on the armrests of the wheelchair forcefully, and at the same time, with the help of the strength of the waist and legs, slowly stand up. During the process of standing up, it is necessary to gradually transfer the body's center of gravity from the buttocks to the feet to maintain body balance. After standing up, it should be ensured that the feet are separated shoulder-width apart, and then proceed to the next step after standing firm. However, the current problem is that the lower limb strength of patients is generally weak. When getting up, the lower limbs cannot bear the pressure of the body alone and cannot get up solely relying on the strength of the lower limbs. They still need to press down on the armrests with both hands to borrow strength to get up. However, the direction of pressing down on the armrests with both hands to borrow strength is vertically downward, which is relatively laborious, and generally requires the assistance of family members to stand up, which makes it difficult for patients to get up independently from the wheelchair.
[0004] Therefore, how to design an auxiliary getting-up structure for a wheelchair and a wheelchair with the same that is more labor-saving when getting up from the wheelchair and can meet the independence to a certain extent is a technical problem that has not been solved in the prior art. Summary of the Utility Model

[0066] The following will describe this application in detail with reference to the drawings and in combination with embodiments. Embodiment 1
[0067] This embodiment provides an auxiliary getting-up structure for a wheelchair, as Figures 3 - 5 shown, including: armrests 1 and handles 2; where there are two armrests 1, which are suitable for being fixedly installed on the wheelchair for hand support, and are provided with a handle installation cavity 11 having an end opening; there are two handles 2, which are respectively telescopically installed in the two handle installation cavities 11 through a telescopic structure via the end opening, and a grip 21 is fixedly arranged at the non-inserted end; both of the two handles 2 have a storage state of being stored in the handle installation cavity 11, and a protruding state of protruding from the handle installation cavity 11 through the telescopic structure and, after reaching the outermost end, being limited and fixed at the outermost end by a limiting structure.
[0068] When a patient gets up with the aid of the auxiliary getting-up structure of this embodiment, the hand pushes the grip 21 to push the handle 2 to the outermost end through the telescopic structure, then holds the grip 21 and rotates and pulls backward, and the handle 2 is limited and fixed by the limiting structure; when getting up, the patient holds the grip 21 with both hands and pulls backward forcefully, and stands up by the backward pulling force and the strength of their own lower limbs. The auxiliary getting-up structure of this embodiment, when the patient gets up, pulls the grip 21 backward, and can use the strength of the upper limbs, torso and lower limbs to overcome their own gravity and pull themselves up, and can meet independence to a certain extent.
[0069] As Figure 5As shown, the telescopic structure includes a guiding slideway 3 and a handle bead 31. Among them, there are at least two guiding slideways 3, which are respectively opened on the inner walls on both sides of the handle mounting cavity 11. The handle bead 31 is fixedly arranged on both sides of the handle 2 and can be slidably matched with the guiding slideway 3. The handle 2 is telescopically installed inside the handle mounting cavity 11 through the sliding match between the handle bead 31 and the guiding slideway 3.
[0070] The limiting structure includes a rotating slideway 32 and a bead limiting groove 33. Among them, there is at least one rotating slideway 32, which is opened on the inner wall of the handle mounting cavity 11 along the circumferential direction. The head end is communicated with one end of the guiding slideway 3, and the inner diameter is the same as that of the guiding slideway 3. The opening length is one-fourth of the inner wall circumference of the handle mounting cavity 11. The bead limiting groove 33 is opened on the inner wall of the handle mounting cavity 11, is communicated with the tail end of the rotating slideway 32, and has the same inner diameter as the rotating slideway 32. When the handle 2 extends to the farthest end, the handle bead 31 moves to the end of the guiding slideway 3. Rotate the handle 2, and the handle bead 31 enters the rotating slideway 32 and finally enters the bead limiting groove 33 to limit and fix the handle 2. When the patient needs to get up, extend the handle 2 to the farthest end, the handle bead 31 moves to the end of the guiding slideway 3, then rotate the handle 2, the handle bead 31 moves along the rotating slideway 32 to the bead limiting groove 33, then pull the handle 2 backward to limit and fix the handle 2, and then hold the grip 21 and pull backward to pull up the body by means of the pulling force.
[0071] The bead limiting groove 33 extends a certain length inside the handle mounting cavity 11 in the direction away from the end opening.

After the patient has limited and fixed the handle 2, he or she will press the brake handle 41 while standing up while holding the handle 21. The brake handle 41 will rotate the brake member 44 through the brake line 43 until it comes into frictional contact with the wheel and brake the wheelchair. When the patient is standing up, the wheelchair is braked by the brake structure and will not be displaced due to the pulling force, thus ensuring the safety of the patient when standing up.
[0075] like Figures 7 - 9 As shown, the sleeve limiting structure includes a first limiting member 46 and a second limiting member 47; wherein the first limiting member 46 is fixedly arranged in the hollow inner cavity of the armrest 1, is provided with a sleeve limiting hole 49, and is close to the brake handle 41; the inner diameter of the sleeve limiting hole 49 is larger than the outer diameter of the brake line 43 and smaller than the outer diameter of the brake line sleeve 45; the second limiting member 47 is suitable for being fixedly arranged on the wheelchair, is provided with a long hole 48, and is close to the brake member 44; the long hole 48 is used to limit the passage of the brake line sleeve 45 and allow the brake line 43 to pass through; the outer wall on one side of the handle 21 located at the long opening 4 is provided with a bolt through hole 51, and the inner wall on the other side is provided with a bolt through hole 51.
