1. Field of the Invention
The present invention relates to a wheel chair and, more particularly, to a motorized wheel chair.
2. Description of the Related Art
A conventional motorized wheel chair comprises a main body having a seat, an electric power drive device mounted on the main body, and a battery mounted on the main body to supply an electric power to the electric power drive device so as to drive the wheel chair. However, the battery cannot be mounted on and detached from the main body easily and conveniently, thereby causing inconvenience to a user in maintenance and replacement of the battery.
In accordance with the present invention, there is provided a motorized wheel chair, comprising a main body having a seat and two support rods located under the seat, a battery mounted between and supported by the support rods of the main body, and two rotation retaining members each rotatably mounted on a respective one of the support rods of the main body and each rotatable to rest on the battery to retain the battery on the main body.
The primary objective of the present invention is to provide a motorized wheel chair having a battery that is mounted on and detached from a main body easily, quickly and conveniently, thereby facilitating a user mounting and detaching the battery.
Another objective of the present invention is to provide a motorized wheel chair, wherein the user only needs to hang the elongated slides of the battery on the support rods of the main body, to rotate the rotation retaining members and to press the rotation retaining members on the elongated slides of the battery so as to attach the battery to the main body, so that the battery is mounted on the main body easily and conveniently.
A further objective of the present invention is to provide a motorized wheel chair, wherein the battery is locked on and unlocked from the support rods of the main body by rotating the rotation retaining members, so that the battery is mounted on and detached from the main body easily and quickly.
A further objective of the present invention is to provide a motorized wheel chair, wherein the battery is retained by the rotation retaining members, so that the battery is mounted on the main body rigidly and stably.
Further benefits and advantages of the present invention will become apparent after a careful reading of the detailed description with appropriate reference to the accompanying drawings.
Referring to the drawings and initially to
Referring to
Each of the rotation retaining members 3 is rotatably mounted on an end portion of the respective support rod 12 of the main body 1 so that each of the rotation retaining members 3 is rotatable about the respective support rod 12 of the main body 1. Each of the rotation retaining members 3 is rotatable to rest on a respective one of the elongated slides 20 of the battery 2. Each of the rotation retaining members 3 has a side formed with a snapping member 30 that is movable and is snapped into the snapping hole 200 of the respective elongated slide 20 of the battery 2 so that each of the rotation retaining members 3 is snapped onto the respective elongated slide 20 of the battery 2 to retain the battery 2 on the main body 1. After the battery 2 is mounted on the main body 1, the battery 2 is connected to the electric power drive device 10 to supply an electric power to the electric power drive device 10 so as to drive the wheel chair.
In operation, referring to
Accordingly, the user only needs to hang the elongated slides 20 of the battery 2 on the support rods 12 of the main body 1, to rotate the rotation retaining members 3 and to press the rotation retaining members 3 on the elongated slides 20 of the battery 2 so as to attach the battery 2 to the main body 1, so that the battery 2 is mounted on the main body 1 easily and conveniently. In addition, the battery 2 is locked on and unlocked from the support rods 12 of the main body 1 by rotating the rotation retaining members 3, so that the battery 2 is mounted on and detached from the main body 1 easily and quickly. Further, the battery 2 is retained by the rotation retaining members 3, so that the battery 2 is mounted on the main body 1 rigidly and stably.
Although the invention has been explained in relation to its preferred embodiment(s) as mentioned above, it is to be understood that many other possible modifications and variations can be made without departing from the scope of the present invention. It is, therefore, contemplated that the appended claim or claims will cover such modifications and variations that fall within the true scope of the invention.
