The main frame 2 of the car 2 is separated and facilitates the connection of the other types of seats 3 to the main body frame 20 of the scooter 2. The universal follower caster 32 and the hinged shaft 33 of the seat 3 can support the seat 3 on a three- or more-wheeled scooter 2, which is driven by a universal caster. 32 and the hinged shaft 33 are stably supported by at least three points, and the safety of the seat 3 is ensured by the universal follower caster 32 being directly supported on the road surface, and the body frame 2 of the scooter 2 is provided with a A bearing housing 24 connected to the hinge shaft 33 is for connecting the seat 3 to the scooter 2, and the one hinge shaft 33 and the universal follower wheel 32 are spaced apart from each other in positional arrangement to ensure the seat 3 Stability, and the two hinged shafts 33 are located on the same straight line. In principle, the two hinged shafts 33 are like a hinged shaft 33, and the center lines of the two hinged shafts 33 are parallel to the rear axle of the scooter 2 This seat 3 can freely rotate on the scooter 2 around the articulated shaft 33 over a range of angles. When the person moves forward, the center of gravity of the person can cause the universal follower caster 32 to leave the road surface, as shown in the fourth figure, so that the seat 3 and the driver are completely supported on the main body frame 2 of the scooter 2, This can be achieved by adjusting the position of the splicing shaft 33 on the main body frame 2() or the seat 3 of the scooter 2, and the universal follower caster 32 can be arranged to be close to 1288634. The pavement is used as a safety-proof anti-turning wheel. 'Under this structural condition, the seat 3 can still rotate freely on the scooter 2 around the hinged shaft 33 within a certain angle range. The contemporary walker 2 is traveling in the forest. When the flat road surface is slightly tilted backwards, the seat 3 will be automatically supported by the universal follower caster 32 on the road surface, such a scooter 2 driving performance scale-partial Prayar, but the ship has the seat 3 It is more secure than the one with the m-fixed wheel. On the rear-wheel-drive scooter, the driver sits on the seat 3 and moves forward. The seat 3 is tilted up, at which time the seat 3 is connected by two money shafts 33 and the lower limbs of the patroller The universal caster% follower away from the road 'universal follower so small castors 32 may be used in the seat 3, the scooter 2 and 3 still spread across heteroaryl (iv) blocking the greater trochanter. The replacement socket (10) of the present invention (4) Gu 24 and the socket 3 of the socket 3 is closer to the steering front wheel 2 than the receiving socket n of the conventional scooter ^, so the equivalent load center of the scooter 2 of the present invention and the conventional scooter 1 etc. The effect load center is more advanced than the lower one, so the scooter 2 of the present invention is more dynamic and stable and easy to turn. According to another embodiment of the present invention, as shown in the seventh figure, the driving device is disposed at the steering front wheel 21 of the scooter 2, so that the scooter 2 is driven by the front wheel, and the dip carrier wheel 25 is moved to the more advanced drive. At the steering front wheel 21 of the device, the hinge shaft 33 and the bearing housing 24 of the shop 3 are also closer to the steering front wheel 21 of the 1288634 with the driving device, and the scooter 2 and the seat 3 of the steering front wheel 21 can be driven Like the wheelchair, the socket 30 is rotated around the seat 3, and if the second carrier wheel 25 is turned to the rear position, the driving ability of the steering wheel 2 driven by the steering front wheel 21 will be improved, and the two hinged shafts are improved. 33 and the universal follower casters jointly share the weight load of the driver. The two money shafts 33 will partially load the scooter 2, so the two hinge shafts 33 should be arranged in the steering front wheel 21 in the control direction of the scooter 2. Between the two rear load wheels 25, and the rear load wheel 25 of the scooter 2 should be arranged between the two hinged shafts and the universal follower casters 32. The load center of the seat 3 should be closer to the two hinges. The center line of the shaft 33 makes two The connecting shaft 33 can share more load, and the universal follower caster 32 is subjected to less load, and the position of the two hinged shafts 33 on the main frame 2 of the scooter 2 is opposite to that of the conventional scooter 1 seat ίο. The steering front wheel 21 can be closer to the steering front wheel 21, so that the steering front wheel 21 can share more load and have better steering friction, and the position of the hinge shaft 33 on the main frame 2 of the scooter 2 can be closer to the driving steering wheel. 21, to increase the driving ability of the steering front wheel 21, and the two rear load wheels 25 can be closer to the driving steering front wheel 21, so that the steering performance of the driven steering wheel 2 of the steering front wheel 21 is better, and is driven by the steering front wheel 21. The scooter 2 can be more practical and can be rotated in place like a wheelchair, and therefore, the scooter 2 of the present invention is more dynamic and stable and easy to turn. 1288634 Also, in another embodiment, as shown in the figure, a seat 4 is mounted on the extended contact frame & the child seat 4 can be replaced by a storage basket or a second additional one. The additional seat can be added to the extended universal sliding foot (10). The main body frame of the scooter 2 is like a squat head, and the hinged shaft 33 is also missing. The main frame of the seat 3 and the scooter 2 is added. Easy to separate, no _ seat 3 can be connected to the seat spicy 31 to suit different purposes 'The main frame 2 of the scooter 2 can be set to be shorter in length, and the handle of the steering control can also be bent downwards. After the shop 3 is separated from the main body frame 20 of the scooter 2, all the vehicle components can be placed in the rear car A of the passenger car, which can be conveniently carried. The conventional scooter 1 can also be installed with the seat 3 of the present invention to improve its safety and drivability. In summary, the embodiment of the present invention has indeed been able to achieve the intended purpose and effect of use 'and has not been known to have the same structural features, the public is the first, so the invention can meet the requirements of the invention patent, To apply, I urge you to conclude the case as soon as possible and approve the patent.
