Abstract
The utility model discloses a linkage structure of stand -type wheelchair, including wheel wheel -chair automobile body, wheel wheel -chair automobile body includes the frame of both sides and installs the seat aggregate unit between the frame of both sides, seat aggregate unit includes folding mechanism and drives actuating cylinder, one set of folding mechanism of difference on the frame of both sides, folding mechanism includes actuating lever, transmission piece and seat installation pole, actuating lever, transmission piece, seat installation pole become hinge four bars structure with the connected to the frame of corresponding one side, drive actuating cylinder's cylinder body and piston end and take turns wheel -chair automobile body and actuating lever hinged joint with both sides respectively. The utility model has the advantages of, utilize the cylinder drive to set up the hinge four -bar linkage on the frame of left and right both sides to realize wheelchair folding function, the convenient conversion between position of sitting and station appearance of help patient.
Description
Technical field
This utility model relates to daily living article technical field, particularly relates to a kind of stand-up wheelchair framework.
Background technology
Current, electric wheel-chair vehicle is called electric wheelchair for short again, is the instrument that the special population of such as people with disability, old and weak person, the person of walking with difficulty, limbs wounded body and medicinal rehabilitation and so on is ridden instead of walk.The macrostructure of electric wheel-chair vehicle is known, specifically comprise car body and motor drive mechanism, car body comprises vehicle frame, wheel (a pair front-wheel and pair of rear wheels), seat support, the chair back and handrail, and motor drive mechanism comprises electric walking wheel support, controller and a pair electric walking travelling wheel.The technical information about electric wheel-chair vehicle is no lack of in disclosed Chinese patent literature.
Be not limited to exemplify, although have corresponding technique effect separately, but there is following logical fraud: the vehicle frame due to car body is designed to the chair fixed, when user needs to stand, still need to help people to help to leave wheel-chair, for some be only legs and feet inconvenience, but still there is the user of standability, the structure of wheel-chair complexity becomes the obstruction stood from wheel-chair on the contrary, such as the patient on electric wheel-chair vehicle is taken advantage of (also to claim outdoor) to go sightseeing out of doors when accompanying electric wheel-chair vehicle by entourage and push to sit, visit, when stroll state is low advanced, needs of patients stands, other people are so just needed to help leave wheelchair and stand, wheel-chair please under money what play auxiliary moving, obstruction is constituted to standing of user.
Therefore, those skilled in the art is devoted to develop a kind of wheel-chair that user can be helped to stand, to make up the deficiency of existing wheel-chair product.
Summary of the invention
Because the above-mentioned defect of prior art, technical problem to be solved in the utility model is to provide a kind of linkage structure of stand-up wheelchair, helps patient to change between sitting posture and stance to realize electric wheel-chair vehicle.
For achieving the above object, this utility model provides a kind of linkage structure of stand-up wheelchair, comprise wheel-chair car body, described wheel-chair car body comprises the vehicle frame of both sides, be arranged on the fold mechanism between the vehicle frame of both sides and drive cylinder, the vehicle frame of described both sides is equipped with a set of fold mechanism respectively, described fold mechanism comprises drive rod, drive block and chair mounted bar, described drive rod, drive block, the vehicle frame of chair mounted bar and corresponding side connects into hinge four-bar structure, the cylinder body of described driving cylinder and piston end respectively with both sides wheel-chair car body and drive rod chain connection.
In better embodiment of the present utility model, between described left and right two drive rods, bracing piece is housed, between the vehicle frame of described both sides, mounting rod is housed, the cylinder body of described driving cylinder and piston end respectively with bracing piece and mounting rod chain connection.
Medicated cushion is equipped with in another better embodiment of the present utility model, described chair mounted bar.
Technique effect
Be described further below with reference to the technique effect of accompanying drawing to design of the present utility model, concrete structure and generation, to understand the purpose of this utility model, characteristic sum effect fully.
The utility model has the advantage of, utilize air cylinder driven to be arranged on four-bar linkage on arranged on left and right sides vehicle frame, fold to realize wheelchair, make existing wheelchair can realize conversion at sitting posture and stance.
