Problems solved by technology

If the chain breaks when the wheelchair is in use, the gear bar will not be able to retract smoothly
If the chain breaks during the standing process of the wheelchair, the gear rod will not be able to touch the ground, and the wheelchair will easily slip during the process of standing upright or storing, which is a big hidden danger to the safety of wheelchair users
In addition, in this prior art, the first gear directly drives the second gear to drive the third gear, or the first gear drives an idler gear and then drives the third gear through the idler gear. Due to the effect of the transmission torque , so that the expansion and contraction of the gear rod will be slow, stagnant or paused after the first gear is started. Causes troubles in operation and use, and needs to be improved

Embodiment Construction

[0057] In order to have a further understanding and understanding of the structural features of the present invention and the achieved effects, the preferred embodiments and accompanying drawings are used for a detailed description, as follows:

[0058] see Figure 1A to Figure 3 , the wheelchair device with assisting function of the present invention comprises a side frame set 10, a tripod set 20, a sitting frame set 30, a stretching mechanism 40 and a transmission mechanism 50; the side frame set 10 includes left and right two side frames 11, the side The frame 11 includes an upper side frame 13 and a lower side frame 14 connected to each other. The upper side frame 13 and the lower side frame 14 are slightly curved pipe bodies (or rods) respectively, and the front end of the upper side frame 13 is downward. A sleeve 131 is formed, and the rear end of the upper side frame 13 is downwardly formed into a round seat tube 132, and an abutting piece 133 is provided at an appropri...

Abstract

The invention relates to a wheelchair device with an assistant function. The wheelchair device comprises a side frame group containing two side frames, two stand pipes, a console group containing two consoles, a deployment mechanism, at least one driving gear group and at least one transmission gear, wherein a front cross rod is pivoted between the two side frames, each side frame is provided with a wheel set; the two stand pipes are separately arranged in sleeves, each stand pipe contains a rack division; the two consoles are arranged above the side frame group, the front end of the console group is pivoted with the side frame group, a back cross rod is pivoted between the two consoles; the two ends of the deployment mechanism are separately connected with the front and back cross rods in a transmission manner; the driving gear group is arranged on the front of the side frames and linked with the front cross rod; and the transmission gear is pivoted on the front end of the side frames. By using the wheelchair device of the invention, when two lifting arms move up, the two stand pipes can move down so that the applied force on the stand pipes can not be easy to disperse in the driving process, the two stand pipes can move down smoothly and the safety of the wheelchair device with the assistant function can be increased.

Description

technical field [0001] The present invention relates to a wheelchair structure, in particular to a wheelchair device with an assisting function that can smoothly, conveniently and safely assist an occupant to stand. Background technique [0002] Wheelchairs are the main means of transportation for people with disabilities, serious diseases or injuries. Even so, when users with serious diseases or inconvenient conditions want to stand, they still need assistance from others. For wheelchair users who take care of these major diseases, the most important considerations are safety issues and the moment when the wheelchair is taken off and on. Since the caregiver has to support the weight of the wheelchair user and pay attention to the positioning of the wheelchair, it is quite inconvenient and strenuous, and the wheelchair user may fall or fall if he is not careful. Take off and land very carefully to prevent further dangers from happening. Furthermore, due to the long-term la...
