When there is no need to drag items, the folding cart 100 is in a folded state, taking the shape of a trolley case. At this time, the folding volume is the smallest, which is convenient for the user to carry when not in use, and the folding bike 100 can be moved and transported only by dragging the handlebar 150 .

In this embodiment, the folding bicycle 100 includes three states, namely, the unfolded state, the half-folded state and the folded state, which are suitable for different occasions. It is convenient for users to ride, load and move. Easy to use, simple in structure and easy to carry.

Example 3

This embodiment provides a folding bike 100 , similar to Embodiment 2, the bike includes a front body 110 , a rear body 120 , a front wheel assembly 130 , a rear wheel assembly 140 , a handlebar 150 and a seat 160 .

The front body 110 is rectangular and has opposite first ends 111 and second ends 113 , and the rear body 120 is also rectangular and has opposite third ends 121 and fourth ends 123 . The second end 113 of the front body 110 is rotatably connected to the third end 121 of the rear body 120 through a hinge 170 . The electric foldable bicycle 100 has an unfolded state in which the first end 111 and the fourth end 123 are far away from each other.

The car stool 160 includes a stool body 161 and a telescopic rod 163 . A card slot 167 is provided under the stool body 161 , and a second card key 165 is provided on the telescopic rod 163 . The detachable connection between the stool body 161 and the telescopic rod 163 can be realized through the cooperation of the slot 167 and the second key 165 . The difference of this embodiment is that the above-mentioned stool body 161 is a hollow structure. Under the condition that the stool body 161 is sufficiently rigid, it is designed as a hollow structure, and articles can be stored in the cavity.

When the user finishes using the foldable bike 100 in the unfolded state and needs to pack the foldable bike 100, the user drives the car stool 160 or the rear car body 120 to make the rear car body 120, the rear wheel assembly 140 and the car stool 160 Rotating around the central axis of the hinge 170 , the front body 110 and the rear body 120 are in close contact with each other until the first end 111 and the fourth end 123 are side by side in a half-folded state. The stool body 161 is removed from the telescopic rod 163, and the stool body 161 is clamped on the handlebar 150 by engaging the slot 167 with the second key 165 on the handlebar 150. At this time, the folding bike 100 is in the shape of a trailer. The stool body 161 is accommodated through the cooperation of the card slot 167 and the card key. The user in the form of a trailer can directly move the folding bike 100 by dragging the handlebar 150 . The storage surface formed by the front body 110 and the rear body 120 can also carry the goods of the user.

The handlebar 150 includes a rope 155 , a first engaging part and a second engaging part. In this embodiment, the first engaging part is a telescopic head 153 , and the second engaging part is a locking pin 157 . One end of the telescopic head 153 is connected with the rope 155 . The handlebar 150 also includes a bayonet pin 157 , and the bayonet pin 157 is close to the other end of the rope 155 that is not connected to the telescoping head 153 .

Compared with Embodiment 2, this embodiment differs in that the folding bike 100 also includes an electric drive system and a display 180 . The electric transmission is arranged in the rear vehicle body 120 and provides power for the front wheel assembly 130 and the rear wheel assembly 140 through electrical connection. It should be noted that, in other embodiments, the electric transmission device can be arranged inside the front body 110 or outside the folding bicycle 100 ; the electric transmission device is only connected with the front wheel assembly 130 or the rear wheel assembly 140 .

The above-mentioned display 180 is fixed on the handlebar 150, and is located above the handlebar 150, where the user can easily see it. Display 180 is connected to the electric drivetrain.
