Abstract: A fixing member for a vehicle frame joint of scooters is revealed. Both a front frame and a rear frame are disposed with insertion holes correspondingly. A main rod with a pivot is disposed on the front or the rear frame. A fixing unit is arranged between the front and the rear frames. A rotatable disk of the fixing unit is connected pivotally to the pivot of the main rod. One end of a pull handle is disposed on one side of the rotatable disk while the other end is connected to an insertion pin that inserts through the insertion holes of the front and rear frames. Thereby the pull handle and the insertion pin are inserted into or released from the insertion holes of the front and the rear frames by rotating the rotatable disk of the fixing unit so as to connect and disconnect the frames.

Abstract: A vehicle frame joint of a folding scooter is revealed. Connection rods, main hooks with openings facing upward, and side hooks with openings facing downward are disposed between a front frame and a rear frame. While in use, the connection rods of one frame are assembled with or separated from the main and side hooks of the other frame so as to assemble or disassemble the front frame and the rear frame. By the simple design of the joint, even the disabled or users with poor physical health can disassemble/assemble the vehicle frame of the folding scooter easily by themselves.

Abstract: A quick disassembly structure of seat for a scooter has a seat which is provided with two support leg units and a seat section assembled with the two support leg units. A frame major body is provided with pivot mounts on which accommodation grooves are provided for receiving the ends of support leg units, and engaging slots are provided on the side walls of the accommodation grooves for engaging with tenons provided at the lateral sides of the support leg units' ends. Latch pieces are hinged on the upper edges of the pivot mounts so as to cover the engaging slots of the pivot mounts.

Abstract: A collapsible frame structure of a scooter is provided with a front and a rear frame mutually overlapped with each other and a collapsible unit is provided at the abutment between the front and the rear frame. The collapsible unit includes two connecting plates provided respectively at both sides of the front and the rear frames. Both ends of each connecting plate are pivotally connected respectively to the front and the rear frames. Further, latches and strikes capable of locking correspondingly with each other are respectively provided at both sides of the front and the rear frames. By this simple-design collapsible unit, manufacturing cost of the collapsible frame structure of scooter can be decreased, unfolding and collapsing of the front and the rear frame can be facilitated and robustness after the unfolding of the front and the rear frames can be ensured.

Abstract: A steering device includes: a main body mounted on an electric vehicle; a pivot axle unit mounted rotatably to the main body and having opposite rod portions extending outwardly and respectively from opposite lateral sides of the main body; a control unit coupled to the pivot axle unit for generating a control signal associated with forward or rearward movement of the electric vehicle in response to rotation of the pivot axle unit relative to the main body; and an operating unit operable to drive rotation of the pivot axle unit and including two mounting members that are connected respectively to the rod portions of the pivot axle unit, and a connecting member interconnecting the mounting members. Each mounting member has radially extending operating rods.

Abstract: A power lever for scooters is reveled. The power lever is arranged at one of the two sides of a scooter stem and is electrically connected with a power switch and a controller both of which are mounted in the scooter stem. Moreover, a linkage lever is disposed on the other side of the scooter stern, opposite to the power lever while an auxiliary lever is connected between the power lever and the linkage lever and is located on a rear side of the scooter stern. Thereby users can use the other hand to operate the power lever so as to avoid safety problems caused by a stop of scooters in the road in the case the user who feels a sudden pain in one hand is unable to drive the scooter.

Abstract: A locating member for locating scooter seats is revealed. The locating member includes a seat and a support rod, pivoted to each other. A control rod disposed with a locking part and a returning member is pivoted to the seat. The other end of the returning member is fixed on the seat. The support rod is arranged with a locating disk. The locking part of the control rod is locked into a locating part of the locating disk so as to fix the seat at a proper position with the required angle. Thus users can ride scooters conveniently. Moreover, two ends of the control rod away from a pivot region are respectively disposed with a first grip and a second grip and users can choose freely one grip to pull the control rod. Thus the elderly, the disabled and even the handicapped can operate and rotate the seat conveniently.

Abstract: A vehicle chassis includes a first chassis part, a second chassis part, and a coupling device. The first chassis part has an upwardly extending post. The coupling device interconnects removably the first and second chassis parts, and includes a coupling block, a spring-loaded latch unit, and a lever. The coupling block is provided on the second chassis part at a position corresponding to the post of the first chassis part. The latch unit is mounted movably on the post, and is capable of releasable engagement with the coupling block when the coupling block is brought toward the post, thereby interconnecting removably the first and second chassis parts. The lever is coupled to the latch unit, is disposed adjacent to the post, and is operable so as to disengage the latch unit from the coupling block to permit disassembling of the first and second chassis parts.

Abstract: A motor-driven vehicle includes: a chassis; a post extending upwardly from the chassis and having an upright engaging wall formed with an engaging hole; a battery housing seated on the chassis adjacent to the post and including a mounting wall disposed adjacent to the engaging wall; a coupling device including an engaging rod having a pivot portion pivoted to the mounting wall of the battery housing, and an engaging portion extending from the pivot portion, the engaging rod being pivotable relative to the battery housing between an engaging position, where the engaging portion extends into the engaging hole, and a disengaging position, where the engaging portion is disengaged from the engaging hole; and a biasing member for urging the engaging rod to the engaging position.
