Document Type and Number:
WIPO Patent Application WO/2018/068620
Kind Code:
A1
Abstract:
A trailer bike comprises a first bicycle (1), at least one second trailer cycle (2), and at least one connection structure (3). The trailer cycle (2) comprises a front vertical fork (21) capable of changing a direction. The connection structure is a three-pronged connecting rod consisting of a first prong (31), a second prong (32), and a straight rod (33). The first prong is connected to an upper end of the front vertical fork of the second trailer cycle. The second prong is connected to a lower end of the front vertical fork of the second trailer cycle. The straight rod is connected to the first bicycle. A quantity of the trailer cycles is the same as a quantity of the connection structures. The trailer bike can be employed to implement a direction-changing function of a rear cycle without arranging a shaft structure. The trailer bike is simple in structure, and low in cost, and adopts the three-pronged connecting rod structure to enhance the stability of the second trailer cycle.
