Abstract

The present invention provides a battery carrier sliding device for the electric wheelchair, wherein a battery box for the electric wheelchair can be disconnected or reconnected through a manual lockable unit. The present invention provides an improved design for a battery carrier sliding device for the electric wheelchair that utilizes lockable units to manually detach or reattach the battery box by pulling or triggering the lockable unit. The lockable unit is comprised of a connecting belt and two flexible inserting units, wherein holes are formed on the supporting units respectively to correspond the flexible inserting units so that the battery box can be located securely onto the electric wheelchair. The battery box is comprised of a carrying function in such that the structures or the types of batteries do not need to be altered. Various types of batteries can be utilized with the present invention. The present invention provides an improved battery box that can fulfill the needs of the market.

Claims

1. A battery carrier sliding device for an electric wheelchair, comprising:

at least one sliding device, located on a supporting unit of the electric wheelchair;

a battery box, located on the sliding device, wherein the battery box slides along a horizontal direction of a centre-line point of two wheels of the electric wheelchair, wherein a handle is formed on a locking surface of a lockable unit; and

the lockable unit, further comprised of a connecting belt and two flexible inserting units, wherein the flexible inserting units are connected respectively to both ends of the connecting belt, the two flexible inserting units are located with respect to both ends of a locking surface of the battery box, further, two holes are formed on the supporting unit, wherein the two holes of the supporting unit are located to correspond to the two flexible inserting units so that the holes, the flexible inserting units and the connecting belt are connected in a same axis, the lockable unit is utilized to lock the battery box onto the electric wheelchair in order to restrict the horizontal sliding movement of the battery box along the centre-line point of the two wheels of the electric wheelchair.

2. The battery carrier sliding device of the electric wheelchair of claim 1, wherein the flexible inserting units further comprise an inserting shaft, a flexible element and a cover, wherein the inserting shaft comprises a flexible end and a connecting end, the inserting shaft is inserted inside the flexible element, and the cover shields the inserting shaft and the flexible element, the flexible end and the connecting end of the inserting shaft are both exposed outside the cover, both ends of the connecting belt of the lockable unit are connected respectively to the connecting ends of two inserting shafts.

3. The battery carrier sliding device of the electric wheelchair of claim 1, wherein the sliding device further comprises sliding trenches and two sliding bases, the battery box is located on the two sliding bases, and the two sliding base are located in the two sliding trenches so that the battery box can utilize the sliding bases to move along the sliding trenches in a horizontal direction.
