AI Technical Summary

Problems solved by technology

[0008] 1. The existing bicycle folding mechanism is complex and cumbersome, and the folding and unfolding process consumes a lot of time;
[0009] 2. The frame of the existing bicycle is integrated. When a part of the frame is damaged, the entire frame needs to be replaced and repaired. The replacement cost is relatively large, and because the overall frame is bulky, the maintenance is difficult;
[0010] 3. The disassembly process of each part of the damaged frame is cumbersome, and further simplified disassembly is required;
[0011] 4. The volume after folding is still relatively large, which is not easy for users to carry and store

Embodiment 1

[0066] Embodiment 1: as Figures 1 to 18 The shown foldable bicycle includes: a front wheel assembly 3, a saddle assembly 2, a front wheel assembly 1, a rear wheel assembly 4 and an X-shaped center frame that can be combined in the middle.

[0067] 1. Front assembly 3:

[0068] The head assembly 3 includes a hollow head rod 31 , a transmission rod 30 , a three-way support 34 and a ring-shaped handrail 33 for holding by hand or resting on an elbow. Wherein: the upper end of the transmission rod 30 is fixed on the tee support 34, the lower end of the transmission rod 30 extends into the hollow headstock rod 31; on the transmission rod 30.

[0069] Specifically, the upper end of the hollow headstock rod 31 is movably mounted on the transmission rod 30 near the three-way support 34 through the bearing, and the hollow headstock rod 31 is fixed on the outer ring of the bearing, so when the transmission rod 30 is rotated, the empty headstock can not be twisted. pole.

Embodiment 2

[0151] Embodiment 2: as Figures 19 to 21 Compared with Embodiment 1, the shown foldable bicycle is characterized in that the front assembly 3 of the foldable bicycle in this embodiment has a locking device.

[0152] The ring handrail 33 of the front assembly 3 includes a side handle 332, a front end handle 331 and a straight section 333 fixed to the tee support 34, the front end handle 331 is provided with an opening, and the front end handle 331 at the opening is slidably connected with a locking sleeve 35 , the locking structure is located between the locking sleeve 35 and the front handle 331, and the locking structure adopts an elastic buckle locking form.

[0153] Through the sliding of the locking sleeve 35, the ring-shaped handrail 33 can be switched between closed and open states. When the handrail is in the open state, locking objects such as railings can be put into the circle of the handrail, and then slide the locking sleeve 35 Close the armrest, so that the armr...

Embodiment 3

[0161] Embodiment 3: as Figures 23 to 27 A kind of folding bicycle shown, compared with embodiment 1, it is characterized in that: the front assembly 3, saddle assembly 2, front wheel assembly 1, rear wheel assembly 4 and X-shaped central frame of the folding bicycle in this embodiment The connection method adopts a quick splicing structure instead of fasteners such as screws and bolts.

[0162] The inner wall of the first installation port 510 is provided with a buckle groove 90, and the first connecting part 310 is provided with a movable fastening mechanism, and the movable fastening mechanism includes a release button 8, a connecting rod and a button that can cooperate with the buckle groove 90. fastening block 9, the fastening block 9 is slidingly or rotationally connected with the first connecting part 310, and the connecting rod connects the release button 8 and the fastening block 9, any one of the release button 8, the connecting rod or the fastening block 9 An elas...

Abstract

The invention discloses a folding bicycle which comprises a bicycle head assembly, a front wheel assembly, a saddle assembly, a back wheel assembly and an X-shaped center frame. The bicycle is in an X shape when the bicycle is in a normal service state, a folding and positioning mechanism of the bicycle is located on the X-shaped center frame, a user can enable the X-shaped center frame to rotate by canceling the limitation of the positioning mechanism to achieve the purpose of folding the bicycle, and the folded bicycle is in an I shape. The positioning mechanism adopts an annular press type press button, positioning can be relieved by pressing the press button for one time to fold the bicycle without needing to take off positioning pins or screws, the needed operation time in the process of folding the bicycle is greatly saved, the folding process is quite convenient and fast, the folded bicycle is small in size and exquisite, and the appearance of the folded bicycle is in accordance with the aesthetics of modern people.
