Description

Technical Field

[0001] This utility model relates to the field of wheelchair technology, and in particular to a foot pedal fine-adjustment structure and a wheelchair. Background Technology

[0002] In the actual use of wheelchairs, the adjustable angle of the footrests plays a crucial role in the user's comfort and experience. Traditional wheelchair footrests typically have a fixed angle, making it impossible to flexibly adjust them according to different users' physical conditions, sitting postures, and specific usage scenarios. For example, for users with limited lower limb joint mobility, a fixed-angle footrest may lead to excessive tension in leg muscles and poor blood circulation, increasing user fatigue and discomfort. For people who need to sit in a wheelchair for extended periods, non-adjustable footrests cannot meet their diverse needs for leg support angles at different times.

[0003] Furthermore, existing footrests have shortcomings in securing the user's feet. Most footrests lack dedicated foot securing mechanisms or employ overly simplistic methods, making it easy for the user's feet to slip during wheelchair movement. This not only compromises safety but can also lead to injury. This is a pressing issue for people with mobility impairments. Therefore, to address these shortcomings in existing technology, it is necessary to design a footrest fine-adjustment structure and wheelchair to improve wheelchair performance and user experience.

[0004] Therefore, in view of the shortcomings of the existing technology, it is necessary to design a foot pedal fine-adjustment structure and a wheelchair to solve the above problems. Utility Model Content

[0005] To overcome the shortcomings of the prior art, the present invention aims to provide a foot pedal fine-adjustment structure and a wheelchair.

[0006] To achieve the above and other related objectives, the technical solution provided by this utility model is: a foot pedal micro-adjustment structure, including a lifting bracket, a mounting bracket, and a pedal. The mounting bracket is fixed to the movable end of the lifting bracket. The mounting bracket is configured as a U-shaped tube structure and includes a middle tube and side tubes connected to both sides of the middle tube. The pedal is hinged to the middle tube. The left and right sides of the pedal are connected to the two sets of side tubes through an angle micro-adjustment structure.

[0007] The preferred technical solution is as follows: the angle fine-tuning structure includes a connecting ear, an adjusting bolt and a buffer pad. The connecting ear is fixed to the inner side of the side tube, and a screw hole is provided on the connecting ear. The adjusting bolt is screwed into the screw hole, and the buffer pad is hinged to the top of the adjusting bolt and abuts against the bottom side of the pedal.

[0008] A preferred technical solution is that: the left and right sides of the pedal are equipped with upward-facing side plates, and the side plates are provided with strip holes for straps to pass through.

[0009] The preferred technical solution is that the buffer pad is configured as a cone-shaped structure that is wider at the top and narrower at the bottom and is made of rubber.

[0010] A wheelchair including the aforementioned foot pedal adjustment structure.

[0011] Due to the application of the above technical solution, the beneficial effects of this utility model are as follows:

[0012] This utility model provides a footrest micro-adjustment structure and wheelchair. By setting angle micro-adjustment structures on both sides of the footrest, the footrest angle can be flexibly adjusted according to the user's needs. Users can rotate the adjusting bolts to change the contact position between the cushioning pad and the bottom of the footrest, thereby achieving fine adjustments to the footrest angle. This allows different users to find the most suitable footrest angle, effectively relieving leg muscle pressure, promoting blood circulation, and improving comfort when riding in a wheelchair.
