Chassis device conveniently separated from seat

Abstract

The invention discloses a chassis device conveniently separated from a seat. The chassis device is connected with an upper seat device to form an electric wheelchair; the chassis device comprises an electric walking mechanism arranged at the lower end; the chassis device further comprises a base; the base is arranged at the upper end of the electric walking mechanism; a bearing hole is formed in the upper end face of the base; a multi-core socket or a multi-core plug is arranged on the base below the bearing hole coaxial with the bearing hole, and the base is electrically connected with a multipath signal line through the multi-core plug or the multi-core socket. Through the formation of the bearing hole, the chassis device is conveniently in butt joint with an inserting shaft of the upperseat device, quick mechanical disassembly and assembly are achieved, the convenience of the wheelchair is improved, and aiming at the electric wheelchair, through a multi-core plugging unit arrangedon the base, a function mechanism on the lower chassis is conveniently and electrically connected with and quickly and electrically split with a remote control unit arranged on the upper portion.

Description

technical field [0001] The invention relates to a wheelchair, in particular to a chassis device which is convenient to be separated from a seat. Background technique [0002] As a means of transportation for the physically disabled and the elderly, wheelchairs bring certain convenience. Ordinary wheelchairs generally consist of two parts, the upper seat and the lower chassis. The electric wheelchair improves the traveling mechanism provided on the lower chassis into an electric traveling mechanism, which is convenient for control. However, the seat and chassis of most wheelchairs are integrated and inseparable unless mechanically disassembled, which makes it inconvenient to carry. For example, existing wheelchairs (especially electric wheelchairs) cannot be loaded into the trunk of ordinary private cars It is also inconvenient for transportation and maintenance. For example, when transporting electric wheelchairs in batches, each wheelchair will take up a lot of space, whi...

Problems solved by technology

However, the seat and chassis of most wheelchairs are integrated and inseparable unless mechanically disassembled, which makes it inconvenient to carry. For example, existing wheelchairs (especially electric wheelchairs) cannot be loaded into the trunk of ordinary private cars It is also inconvenient for transportation and maintenance. For example, when transporting electric wheelchairs in batches, each wheelchair will take up a lot of space, which will increase the transportation cost, and it will be difficult to ensure the assembly quality and efficiency if the parts are transported to the bottom and installed; Generally, the seat needs to be disassembled. Due to the complicated connection between the seat and the chassis, the assembly workload after disassembly and repair is large, which makes the maintenance efficiency low.

At the same time, for existing electric wheelchairs, the remote control is located at the upper seat, and it is electrically connected to the lower functional mechanism through an electrical signal line. It is also difficult to separate the electrical connection when the upper seat is separated from the lower chassis.
