1. Field of the Invention
The present invention relates to a vehicle body, and more particularly to a vehicle body for a wheeled vehicle, such as a motorcycle, a scooter or the like.
2. Description of the Related Art
A conventional vehicle body for a wheeled vehicle, such as a motorcycle, a scooter or the like, comprises a front frame, and a rear frame attached to the front frame. However, the rear frame is attached to the front frame by soldering, so that the vehicle body is not assembled easily, rapidly and conveniently, thereby causing inconvenience in assembly of the vehicle body, and thereby increasing costs of fabrication. In addition, the rear frame is attached to the front frame by soldering, so that the rear frame is not combined with the front frame rigidly and stably, thereby decreasing stability of the vehicle body.
In accordance with the present invention, there is provided a vehicle body, comprising a front frame, a rear frame, a control unit. The front frame has a rear end having a mediate portion provided with a support column having a locking hole and two sides each provided with a fixing hook. The rear frame is detachably mounted on the front frame and has a front end having a mediate portion provided with a support post and two sides each provided with a fixing stub onto which the respective fixing hook of the front frame is snapped. The control unit includes a rotation member rotatably mounted on the support post of the rear frame, and a locking hook mounted on the rotation member to move therewith and detachably locked in the locking hole of the support column of the front frame.
The primary objective of the present invention is to provide a detachable vehicle body that is assembled and disassembled easily and rapidly.
Another objective of the present invention is to provide a vehicle body, wherein the rear frame is combined with and detached from the front frame easily, rapidly and conveniently, thereby facilitating a user assembling and disassembling the vehicle body.
A further objective of the present invention is to provide a vehicle body, wherein the fixing hooks of the front frame are snapped onto the respective fixing stubs of the rear frame, and the locking hook of the control unit on the support post of the rear frame is locked in the locking hole of the support column of the front frame, thereby forming a three-point support structure by the fixing hooks, the fixing stubs and the locking hook, so that the rear frame is combined with the front frame rigidly and stably.
A further objective of the present invention is to provide a vehicle body, wherein the fixing screw is extended through the support post of the rear frame and screwed into the support column of the front frame, so that the rear frame is combined with the front frame rigidly and stably.
A further objective of the present invention is to provide a vehicle body, wherein the retaining plate of the locking unit is pressed by the locking hook of the control unit to push the locking bracket toward the battery, so that the locking portion of the locking bracket is locked in the locking bore of the battery so as to fix the battery on the front frame by the locking bracket.

The support post 20 of the rear frame 2 has a substantially U-shaped cross-sectional profile. The rear frame 2 is used to receive electronic elements, such as an engine, a motor, a circuit board or the like not shown in the figures. A cover 8 is mounted on the rear frame 2 to cover the rear frame 2.
The control unit 3 includes a substantially cylindrical rotation member 31 rotatably mounted on the support post 20 of the rear frame 2, a locking hook 30 mounted on the rotation member 31 to move therewith and detachably locked in the locking hole 120 of the support column 12 of the front frame 1, a control handle 35 mounted on an upper side of the rotation member 31 to control movement of the rotation member 31, an elastic member 34 mounted in the support post 20 of the rear frame 2 and biased between the rotation member 31 and the support post 20 of the rear frame 2 to provide a restoring force to the rotation member 31, and a receiving seat 36 mounted on a lower side of the rotation member 31 to receive the elastic member 34. The rotation member 31 is rotatably mounted on the support post 20 of the rear frame 2 by a bolt 32 and a nut 33 so that the rotation member 31 is rotatable about the bolt 32.
The fixing screw 4 is extended through the support post 20 of the rear frame 2 and abutting the support column 12 of the front frame 1.
The battery 6 is detachably mounted on the front frame 1 and has an inside formed with a locking bore 60 aligning with the support column 12 of the front frame 1.
Referring to
The retaining plate 51 of the locking unit 5 is located above the locking hole 120 of the support column 12 and pressed by the locking hook 30 of the control unit 3 to push the locking bracket 53 toward the battery 6, so that the locking portion 54 of the locking bracket 53 is locked in the locking bore 60 of the battery 6 at a normal state. The locking bracket 53 of the locking unit 5 is substantially U-shaped and is formed by a bent bar. The retaining plate 51 and the locking bracket 53 of the locking unit 5 encircle the support column 12 of the front frame 1.
The locking bracket 53 of the locking unit 5 is movably mounted on the support column 12 of the front frame 1 by two support seats 55, and the locking unit 5 further includes two springs 50 each mounted on the locking bracket 53 and each biased between the retaining plate 51 and a respective one of the two support seats 55 to provide a restoring force to the locking bracket 53 to pull the locking bracket 53 outward relative to the battery 6 when the retaining plate 51 of the locking unit 5 is released from the locking hook 30 of the control unit 3, so that the locking portion 54 of the locking bracket 53 is detached from the locking bore 60 of the battery 6.
