Referring to Figures 1 and 2, at least, the seat cushion 13, the rear wheel frame 14, and the rear wheel frame 14 are pivoted behind the frame 连结 by the connecting member i 6 , the connecting member 16 There is a pivot 161 and an elastic frame 162. The 柩 (4) 1-end is connected to the frame 11' and the other end is connected to the rear wheel frame ^4. The elastic frame 16 2 is connected to the frame χ: Between the rear wheel frame 丄4, the frame u can be oscillated about 姊ΐ6 by the amount of deformation of the elastic frame 162. The rear wheel frame 丨4 is connected to the rear wheel group i 5 at the rear end. The rear wheel set 丄5 is a rear wheel of the wheel motor, and a seat cushion 13 for the driver to ride is provided above the switch i. When the conventional tricycle 1 is to be turned, the deformation amount of the elastic frame 16 2 provided in the joint member 6 can be used to make the frame work can be used for the left and right movements with the pivot 丄 6 work as the center. _ After the enchantment i 5 is subject to the large centrifugal force 'to avoid the power tricycle 1 at high speed when the car __ and the center of gravity yaw, the driving safety concerns 1 know the power of the tricycle can be set by the link 1 6 'The large centrifugal force experienced by the outer rear wheel set 15 . However, in 201213181, the power of the tricycle i is in the parking lot, and its body will also form a natural yaw. Therefore, the power of the conventional three-wheeled vehicle is relatively large when it is parked, which makes the parking space greatly reduced. limit. In view of the lack of the above-mentioned power tricycle i, it is to reduce the power of the two-wheeler! The parking space at the time of parking is a problem to be solved in the current vehicle manufacturing. 〃hall. [Summary of the Invention] The problem of the car’s ambition is to buy a vehicle that reduces the power of the z-wheel train. This is a technique for distinguishing the bribes, the parking structure of the city, and the three-wheeled plum (four) frame. And after the touch, the scale green money turns, Na ^ ^ shake #, the rear wheel frame is connected to the connecting rocker arm, the link shake 'connects the rear wheel frame by the bolt _ there ==: screw = rear wheel frame Connected, there is a parking structure, the parking unit is for work, melting; connecting rocker arm and rear wheel frame connecting rocker arm is provided with a barrel, the guiding tube is connected to two: guide: the parking unit is provided by the rear wheel frame Stop broadcast, ,,. There are parking guides and stoppers, which are used to stop the broadcast of the vehicles and to drive the parking guides to drive the broadcasts, and the yarns are produced. : Less: The parking space for electric tricycles when parked. Made by the wheel arm two: provide the parking structure of the electric tricycle from the rear wheel group, "enhance the ^: ^ shock absorber 11, which can be welded to 201213181. The re-technical means of the invention is provided - The parking structure of the electric tricycle is connected to the pivot hole of the rear frame by the connecting portion, and is connected to the wire hole of the connecting portion and the rear frame by the connecting screw, and can make the frame and the connecting frame shake The arm is pivoted at the same time with the pivot bolt (4). It can swing freely from side to side, so that the car body can use the 姊 bolt as the surveying towel. (4) The left and right cranes can be freely used, so that the outer wheel of the rear wheel set can withstand the f The large centrifugal force, and then can avoid the car to shook or heavy ~ deviate from the driving safety concerns, can increase the safety of the car. Another technical means of the present invention is to provide a parking structure for an electric tricycle by providing a limit mechanism on both sides of the pivot portion, the limit mechanism being constituted by a tab which has a vertical portion And the cross arm portion, the cross arm portion can be pressed against the rear wheel frame, whereby the closing mechanism can be formed, and the pivoting and connecting pivoting is the most A of the W that can be made in the swinging The county level, in turn, to increase the safety of the car.
