Combined electric wheelchair headstock

Abstract

The invention provides a combined electric wheelchair headstock. The combined electric wheelchair headstock comprises a direction control module, a motor movement module, a movement control module, an adjustable connection module, a fixed connection module and a supporting module, wherein the direction control module is fixed onto the motor movement module through the connection of a screw and a nut, the movement control module is fixedly connected with the motor movement module through a pair of bowl groups, and the central axes of the direction control module, the motor movement module and the movement control module share the same line; the adjustable connection module is fixedly connected with the movement control module through two symmetric connecting pieces on the side edges; the fixed connection module is connected with the adjustable connection module through a boss, a groove, a connecting ring and a collision lock; the supporting module is arranged on the side edge of the adjustable connection module in a threading manner. The combined electric wheelchair headstock can be matched with different hand-operated wheelchairs and can meet the requirements of different users; all modules are assembled through an embedding way, screws and a collision-lock clamping way, so that convenience in assembling and disassembling can be achieved; after the combined electric wheelchair headstock is separated from the hand-operated wheelchair, each structural module can be disassembled to be stored, so that convenience in storage and carrying can be achieved.

Description

technical field [0001] The invention relates to the field of electric combined wheelchairs, in particular to a combined electric wheelchair head.

Problems solved by technology

This utility model combines the functions of a four-wheel folding wheelchair and a tricycle, but the wheelchair occupant needs to operate the rocker device to provide power, and the physical condition of the lower limb disabled is not good, so it is difficult to go to a far place by manually operating the rocker, so Inconvenient for wheelchair users

In addition, the head of this utility model is bulky, and the disassembly and storage of each module cannot be realized

Finally, this utility model cannot realize the adjustment of the height and width of the front of the car, and has not realized the cooperative use with various types of ordinary wheelchairs
