Description

Improved electric wheelchair with indexing function

The present invention relates to an electric wheelchair, and more particularly to an electric wheelchair with improved indexing function, which uses the first electric push rod, the second electric push rod, the third electric push rod and the indexing mechanism group to change the electric wheelchair lift and The sitting type becomes a lying type, which is convenient for the user to move the bed by the wheelchair, effectively increasing the range of the patient's activity and simply displacing the patient.

In recent years, electric wheelchairs have a variety of designs, such as the seat can be turned, and the handle can be lifted and lowered.

For example, the patent M407733 assists the sitting and rotating auxiliary device, which is a kind of auxiliary auxiliary rotating accessory, which is detachably mounted in front of a mobile vehicle, the mobile vehicle includes a frame, the frame has a frame A front foot bar, and the rotating assisting device includes a base mechanism, a rotating mechanism, and a driving mechanism. The base mechanism includes a base, at least one auxiliary wheel, and a hook detachably coupled to the front foot. The rotating mechanism includes a carrier rotatably mounted above the base mechanism, and a handrail mounted on the carrier, the handrail defining a load bearing space having an access opening. The driving mechanism is configured to drive the rotating mechanism to rotate relative to the base mechanism, thereby controlling the direction of the entrance and exit. The above-mentioned auxiliary sitting design can improve the comfort and safety of people with reduced mobility when moving.

The conventional electric wheelchair is improved by the convenience of the patient's operation. However, the improvement cannot achieve the effect of indexing, and there is no substantial help for the seriously ill person from the wheelchair to the hospital bed, and the use of the beauty is greatly reduced. .

The present invention provides an improved electric wheelchair with an indexing function, comprising an electric motor group, a first electric push rod, a second electric push rod, a third electric push rod and an indexing mechanism group, wherein the first electric push rod is utilized The second electric push rod, the third electric push rod and the indexing mechanism group change the electric wheelchair lifting and change from the sitting type to the lying type, so that the user can move the bed by the wheelchair, and the second electric push rod can be used to lift the wheelchair. Height, the third electric push rod can reinforce the auxiliary wheel, and the first electric push rod can reduce the indexing mechanism by sitting and lying to the patient.

The advantages of this creation are:

1. Simple structural design and convenient operation.

2. The indexing mechanism allows the patient to easily translate from the bed to the wheelchair.

3. Electric drive, low cost of safety.
