Electric wheelchair vehicle

Abstract

An electric wheelchair belongs to the technical field of daily necessities. Including the car body and the electric mechanism, the characteristics are: a buckle lock installation frame is fixed on the seat frame of the car body and at a position corresponding to the lower part of the seat seat, and a buckle lock mechanism is arranged on the buckle lock installation frame; An electric traveling wheel support locking mechanism is fixed on the electric traveling wheel support of the mechanism and at a position corresponding to the buckle lock mechanism, and the electric traveling wheel support locking mechanism cooperates with the snap locking mechanism. When the locking mechanism locks the electric walking wheel bracket locking mechanism, the car body and the electric mechanism are connected as a whole so that the electric wheelchair can automatically walk in an electric drive mode; otherwise, the electric mechanism can be separated from the car body, and the car body is independent Function, so as to meet the user's flexible selection and use requirements.

Description

technical field [0001] The invention belongs to the technical field of daily necessities, and in particular relates to an electric wheelchair. Background technique [0002] Electric wheelchairs, also referred to as electric wheelchairs for short, are transportation tools for special groups such as the disabled, the elderly and infirm, those with difficulty walking, those with limb injuries, and patients in medical clinical rehabilitation. The macroscopic structure of an electric wheelchair is known, and specifically includes a car body and an electric mechanism. Electric travel wheel bracket, controller and a pair of electric travel wheels. There is no lack of technical information about electric wheelchairs in the published Chinese patent documents, such as authorized announcement numbers CN2745544Y (multifunctional electric wheelchair), CN201379725Y (obstacle avoidance electric wheelchair), CN101589979B (multifunctional electric wheelchair), CN201684098U (electric wheelch...

AI Technical Summary

Problems solved by technology

[0003] Although the above-mentioned patents and / or patent application schemes that are not limited to examples have corresponding technical effects, they have the following disadvantages: since the vehicle body and the electric mechanism are integrated with each other, the two cannot be detached as needed. To a certain extent, it affects the flexibility and selectivity of use, because the function of the electric mechanism is to reflect the automatic walking of the electric wheelchair and meet the corresponding walking speed requirements. When people accompany the electric wheelchair and push the patient on the electric wheelchair to go outdoors (also known as outdoor) slowly in the state of sightseeing, sightseeing, and walking, the electric mechanism will not work, but will increase the weight of the car body. Due to the heavy weight, it is laborious to push it manually, and the user may even regard the electric mechanism as a burden

[0004] Perhaps based on the above disadvantages, it is not uncommon for the above-mentioned special population to be equipped with (that is, purchased at the same time) a wheelchair with an electric mechanism and a wheelchair without an electric mechanism. Selection requirements, but objectively not only increases the purchase cost, but also causes troubles for daily collection in non-use state
