Parking structure of electric tricycle

The present invention relates to a parking structure for an electric tricycle, and more particularly to a parking structure for an electric tricycle that can reduce the manufacturing cost of the electric tricycle.

According to the conventional power tricycle 1, as shown in FIG. 1, at least the frame 11, the front wheel 12, the seat cushion 13, the rear wheel frame 14, the rear wheel set 15, and a connecting member 16 are included.

The rear wheel frame 14 is pivotally disposed behind the frame 11 by a connecting member 16. The connecting member 16 has a pivot 161 and an elastic frame 162. The pivot 161 is connected to the frame 11 at one end and connected to the frame 11 at the other end. The elastic frame 162 is disposed between the frame 11 and the rear wheel frame 14 on the rear wheel frame 14. The deformation of the elastic frame 162 allows the frame 11 to be centered on the pivot 161. The left and right swings connect the rear wheel set 15 to the rear end of the rear wheel frame 14. The rear wheel set 15 is a rear wheel of the hub motor, and a seat cushion 13 for the driver to ride is provided above the frame 11.

When the conventional tricycle 1 is to be turned, the deformation amount of the elastic frame 162 provided in the coupling member 16 can further oscillate the frame 11 around the pivot 161 to eliminate the outer rear wheel set. The large centrifugal force that 15 is subjected to avoids the dumping of the power tricycle 1 and the deflection of the center of gravity during high-speed rotation, and the safety concerns caused by the driving. The conventional power tricycle 1 can eliminate the large centrifugal force experienced by the outer rear wheel set 15 by providing the link member 16. However, when the conventional tricycle 1 is parked, its body will naturally form a yaw to one side. Therefore, when the conventional tricycle 1 is parked, the space occupied by it will be relatively large, resulting in a large parking space. Contraction limit.

In view of the above-mentioned lack of the power tricycle 1 in the prior art, it is a problem that the current vehicle manufacturers need to solve the problem of reducing the parking space of the power tricycle 1 when parking.
