electric wheelchair

Abstract

The invention relates to an electric wheelchair, which belongs to the technical field of articles for daily use. The electric wheelchair comprises a car body and an electric mechanism, and is characterized in that a chair seat frame of the car body is fixedly provided with a padlock installation frame corresponding to the position below a chair seat, and the padlock installation frame is provided with a padlock mechanism; an electric traveling wheel support of the electric mechanism is fixedly provided with an electric traveling wheel support locking mechanism corresponding to the position of the padlock mechanism, and the electric traveling wheel support locking mechanism is matched with the padlock mechanism. When the electric traveling wheel support locking mechanism is locked by the padlock mechanism, the car body is connected with the electric mechanism into a whole, so that the electric wheelchair can travel automatically in an electric driving manner; otherwise, the electric mechanism is separated from the car body, the car body acts independently, so that the requirement of a user on flexibility in selection can be met.

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
