Abstract: A detachable transmission mechanism for a wheel chair includes a control unit, two support frames, a suspension frame and a driving device. The channel clamps of the two support frames can be connected to two lower transverse rods of an existing wheel chair and the joining tubes at two sides of the battery unit is connected to the joining pipe so that the battery unit can be fixed beneath a seat of the wheel chair; furthermore, the control unit is positioned on one side of one of armrest of the wheel chair so that in case of the handle being rotated, the vertical shaft, rotary plate and the connecting rod can move relatively and in turn rotate the suspension frame as well as the driving device; and when a control switch is turned on, the driving wheel can be rotated in either forward or reversed direction and thus move the wheel chair forward or backward.

Abstract: A detachable transmission mechanism for a wheel chair includes a control unit, an engaging unit, a battery unit and a transmission device. The original front wheels of the wheel chair can be detached and the hub and the pivot part are mounted to both the upper and lower frames of the wheel chair. The battery unit can be fixed to the wheel chair under the seat thereof. When a control switch is turned on, the driving wheel can rotate in a forward or a reversed direction with the wheel chair being capable of moving forward or backward. By turning the handle, a follower wheel at the bottom of the wheel chair can be rotated to allow the wheel chair making a turn.

Abstract: A build-up light motor driven car includes a car body, which is composed of a car frame and an outer shell enclosing the car frame, and a seat part. The car body is provided with a guide groove at two lateral sides thereof respectively, the guide groove having an engaging part, the outer shell having a shell chamber behind the respective guide groove. The seat part has two seat frames corresponding to the two guide grooves, the seat frames at upper parts thereof being attached with a seat cushion and at lower parts thereof connecting with a horizontal level respectively for locating a battery and the respective horizontal level at an end thereof having an engaging part. The horizontal levels is inserted into the guide grooves such that the engaging parts can be inserted into the joining parts so as to fixed to each other, and the batteries can enter the shell chambers to constitute connection of a circuit such that seat part can be joined to or detached from the car fast.
