Electric wheelchair with connectable and detachable car body and electric mechanism

Abstract

The invention belongs to the technical field of daily articles and relates to an electric wheelchair with the connectable or separable body and electric mechanism. The electric wheelchair comprises a body and an electric mechanism. The body comprises a seat frame and a backrest frame. The electric mechanism comprises an electric wheel support. The electric wheelchair is characterized in that a lock mounting rack is fixed on the seat frame and provided with a locking mechanism, the backrest mechanism is provided with an unlocking mechanism connected with the locking mechanism, and an electric wheel support locking mechanism corresponding to the locking mechanism is fixed to the electric wheel support and matches with the locking mechanism. When the electric wheel support locking mechanism is locked by the locking mechanism, the body and the electric mechanism are connected into a whole so that the electric wheelchair is electrically driven to walk automatically; on the contrary, the unlocking mechanism can be operated to separate the electric mechanism and the body, the body functions independently, and the requirements of users for flexibility in selection and use can be met accordingly.

Description

technical field [0001] The invention belongs to the technical field of daily necessities, and in particular relates to an electric wheelchair with a car body and an electric mechanism that can be connected and detached. 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), CN101...

AI Technical Summary

Problems solved by technology

[0003] Although not limited to the above-mentioned patents and / or patent application schemes for example, although each has corresponding technical effects, there are the following disadvantages: since the vehicle body and the electric mechanism are integrated with each other, the two cannot be separated as required. 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
