- a labor-saving short-stroke link structure includes an upper coupling plate (in the embodiment of FIGS. 1-9, a seat plate), a lower coupling plate, and a hinge between the upper coupling plate and the lower coupling plate.
- the support structure includes a front support bar assembly and a rear support bar assembly; and a drive mechanism for driving the rotation of the support structure, the drive mechanism generates a linear motion to make the upper link plate, the front support bar assembly,
- the parallelogram mechanism formed by the lower link plate and the rear support bar assembly is in an unfolded state or a stowed state;
- the front support bar assembly includes a left front support bar and a right front support bar, and
- the rear support bar assembly includes a left rear support bar and a right
- the driving mechanism is an electric telescopic rod;
- the fixed end of the electric telescopic rod is hinged with the lower connecting plate, and the movable end of the electric telescopic rod is set on the outer ring of the pushing shaft through the coupling head, and one roller is arranged at each end of the pushing shaft
- the roller rolls in the roller groove provided on the left front support bar and the right front support bar, and the lower link plate is further provided with a transition support shaft, and the transition support shaft The end
- the outer surface of the roller is in contact with the roller groove.
- the roller is driven to roll in the roller groove, and the upper connecting plate, the front supporting rod assembly, the lower connecting plate and the rear supporting rod assembly are formed.
- the parallelogram is propped up.
- the adjustable lifting device is raised to a predetermined height (near the maximum opening state)
- the roller is disengaged from the roller groove, and no supporting force is generated, and the upper roller at the top end of the transitional support arm contacts the two side edges of the roller groove to generate support.
- the force, the force arm at this time becomes larger, and the reaction force received by the first electric push rod becomes smaller, so that the adjustable lifting device can be more stable in the open state.
- the advantage of such a support structure is that the initial force can be increased during the ascending lifting device, and the stroke of the electric push rod can be shortened. When the electric push rod is in the maximum state, the force is small, and the structural stability of each member is ensured. Service life.
- the upper roller preferably has a stepped structure, that is, the diameter of both ends is smaller than the intermediate portion.
- a labor-saving short-stroke link structure of the present application can be used for a multi-purpose wheelchair, as shown in the embodiment of FIGS. 1-9, and may also be used in various chair structures, such as a student seat. Car seats, etc.
- the present application also discloses a linkage linkage mechanism for a seat; the seat includes a base, and a grab bar hinged to both sides of the base, a foot pedal hinged to the front end of the base; and a base a linear drive mechanism between the grab bars; a fixed end of the linear drive mechanism is fixedly coupled with the bracket of the base, the movable end is hinged with the lower link of the armrest, and the lower link of the armrest is fixedly coupled with the handrail bar through the fixed joint armrest side plate; In the horizontal state, in the contracted state, the movable end of the linear drive mechanism is in an extended state; in the working state, the movable end of the linear drive mechanism is contracted, thereby driving the lower arm of the armrest to rotate, and the
- a further technical solution is: a middle portion of the lower arm of the armrest is provided with a pedal link, one end of the pedal link is hinged to the lower link of the armrest, and the other end is hinged to the lower middle portion of the front pedal; in the working state, the activity of the linear drive mechanism The end is contracted, thereby driving the lower arm of the armrest to rotate, and the lower link of the armrest rotates, and the pedal link is rotated, so that the coupled front pedal rotates from the rear toward the front for the user to comfort the leg when sitting.
- a linkage linkage for a seat of the present application can be used in a multi-purpose wheelchair, as shown in the embodiment of FIGS. 1-9, and may also be used in the construction of various chairs, such as a folding seat. , car seats, etc.
- the multifunctional wheelchair of the present application has the structure of the base and the adjustable lifting device, and the height and angle of the wheelchair body can be adjusted, and has wider applicability, and is applicable to each The height of the bed, and meet the various needs of lying, sitting, moving, folding, etc.; Because of the sliding detachable structure, the wheelchair body and the base can be used separately, the weight is lighter, and the care worker and the patient's family are reduced.
- the adjustable lifting device also includes a seat plate with a defecation through hole in the center, for supporting the lower leg Part of the front bezel, the front armrest for the user to support and the neck pillow supporting the head for added comfort and higher safety; because of the variety of power drive mechanisms available, manufacturers can rely on different costs And the production focus is flexible; the base is also equipped with a pole frame for pushing the wheelchair and a handrail for supporting the elbow of the user. Place items for external desk panels and foot pedal for supporting the foot, full-featured, strong and durable.
