Multifunctional electric wheelchair

Abstract

The invention relates to a multifunctional electric wheelchair. The wheelchair comprises a seat platform, a chassis platform, a base, connecting supporting rods, a multi-pin connector and a multi-pinsocket, wherein the multi-pin connector and the multi-pin socket are connected with one another in an inserted mode; the seat platform comprises a seat and a rotary shaft fixed at the bottom of the seat; the chassis platform comprises a chassis box body and walking supporting rods arranged on the chassis box body; the base is arranged on the connecting supporting rods and at least provided with asocket; the multi-pin connector or the multi-pin socket is coaxially connected with the rotary shaft at the lower end of the rotary shaft, and the corresponding multi-pin connector or the multi-pin socket is coaxially connected with the socket on the base below the socket; the connection or separation between the seat and the chassis platform is achieved by inserting the rotary shaft in the socketor pulling the rotary shaft out from the socket and by inserting the multi-pin connector at the lower end of the rotary shaft in the multi-pin socket on the base or pulling the multi-pin connector onthe base out from the multi-pin socket at the lower end of the rotary shaft. The combination and separation between the seat and the chassis on the wheelchair can be achieved through the inserted mode, and a wheelchair with required functions can be built and formed by selecting corresponding functional modules according to demands of the functions.

Description

technical field [0001] The invention relates to a multifunctional electric wheelchair. Background technique [0002] The various electric wheelchairs that have been disclosed may have other functions in addition to being used as a means of transportation, such as rotating functions, lifting functions and swing functions (including self-balancing follow-up functions). patent application. Although the seat on these wheelchairs can rotate relative to the vehicle body (chassis part), the seat and the vehicle body part can not be easily separated unless dismounted. And if the rotation of the seat needs to be driven by the driving mechanism, it will be more restricted by the driving mechanism, and it is more difficult to mechanically separate the seat and the car body part easily. However, even if the seat and the car body can be easily separated, if the control wire is arranged on the seat, it will be hindered by the electric connecting wire.

AI Technical Summary

Problems solved by technology

Although the seat on these wheelchairs can rotate relative to the vehicle body (chassis part), the seat and the vehicle body part cannot be easily separated unless they are disassembled.

And if the rotation of the seat needs to be driven by the driving mechanism, it will be more restricted by the driving mechanism, and it will be more difficult to mechanically separate the seat from the car body.

However, even if the seat and the car body can be easily separated, if the control wire is arranged on the seat, it will be hindered by the electric connecting wire. For example, the patent application of the Taiwan region whose publication number is TW466948U has a control wire on the seat. , it is difficult to completely separate the seat from the body for this type of wheelchair

However, the functions of the integrated wheelchair in which the seat and the body cannot be separated are fixed, which is inconvenient for the user to increase the functions of the wheelchair, and it is also inconvenient to carry. For example, the existing electric wheelchair cannot be loaded into the trunk of an ordinary private car; It is also inconvenient for transportation and maintenance, because the overall wheelchair will take up more space, which will increase the transportation cost, increase the disassembly workload during maintenance, reduce maintenance efficiency, and increase maintenance costs

[0003] In addition, the existing electric wheelchairs with different functions are structurally designed for the corresponding functions, that is, wheelchairs with certain functions have a specific structure, resulting in corresponding parts and wheelchairs with different functions. It is impossible to build different functional parts, so it is difficult to adapt to the changing needs of the market for wheelchairs with different functions. During production, parts of hot-selling products will not be produced in time, and parts of slow-moving products will be backlogged. It is difficult to utilize the production capacity of existing production equipment, and it is not convenient to schedule production according to market demand and equipment capacity
