Embodiment Construction

[0013] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail:

[0014] Such as figure 1 As shown, the wheelchair multi-link lifting mechanism includes a transmission mechanism 1, a wheelchair bracket 2, a push rod motor 3 and connecting rod folding mechanisms A, B, and C. The wheelchair bracket 2 is provided with three sets of chute A1, B1, and C1, two of which are The first group of chutes A1 and B1 are vertically placed on the wheelchair bracket 2, and the third group of chute C1 is placed on the wheelchair bracket 2 horizontally. Slot A12 slides, the front end of the bottom is hinged with the chute A11, the rear end of the bottom is hinged with the pin shaft and the front end of the H-shaped drive rod 11, and can slide along the chute A11, the second double X-shaped linkage group B2 top front section and the chute B12 is hinged, the top rear end slides along the chute B12, the bottom front end is hinged ...

Abstract

The invention discloses a multi-connecting rod lifting mechanism for a wheelchair, and aims at providing a mechanism for lifting the wheelchair. The lifting mechanism comprises a push rod motor, a transmission mechanism, and connecting rod folding mechanisms. The key points of the technical scheme are as follows: the push rod motor simultaneously acts on the three groups of connecting rod folding mechanisms under the action of the transmission mechanism to drive the wheelchair to lift, the three groups of connecting rod folding mechanisms are consistent in lifting speeds; a supporting structure is stable. By adopting the lifting mechanism disclosed by the invention, the lifting of the wheelchair is achieved, and the lifting mechanism is stable in structure, convenient to control and high in economy.

Description

technical field [0001] The invention relates to a lifting mechanism, in particular to a wheelchair multi-link lifting mechanism. Background technique [0002] Wheelchairs provide superior mobility tools for the elderly and the disabled to improve their freedom of movement. However, ordinary wheelchairs only have the function of assisting walking, and because the size of the wheelchair is fixed, the height of the wheelchair board from the ground is fixed. In real life, different body types and different usage situations have different requirements for this height. Thin users need a smaller distance, tall users need a larger distance, and users need to bend over to pick up things or transfer from a wheelchair The distance needs to be smaller when reaching the bed, and the distance may need to be larger when the user needs to lift his hand to pick up something or go to the counter to buy something. [0003] Therefore, it is particularly important to design a mechanism that can...
