Problems solved by technology

[0005] Although the handle tube 75 can be made perpendicular to the ground by folding the upper handle stand tube 74, thereby reducing the folded width of the bicycle 7, but when the upper handle stand tube 74 is folded, the front wheel 73 will also be produced synchronously. deflection, so it is not suitable for large bicycles (because the increased width of the front wheel after deflection is large, the overall width of the folded bicycle will increase), so the folding mechanism suitable for reducing the volume of any type of bicycle after folding remains to be studied to develop

Embodiment Construction

[0029] The present invention will be described in detail below with reference to the drawings and embodiments.

[0030] For the convenience of description, in the following embodiments, the same elements are denoted by the same reference numerals.

[0031] Refer to image 3 and Figure 5 , A first preferred embodiment of the bicycle folding mechanism of the present invention is suitable for connecting a handle 11 of the bicycle 1 with a front riser 13 passing through a frame 12, and the handle 11 includes two With the handles 111 on both sides of the longitudinal axis of the frame 12, the bicycle folding mechanism includes a first clamping base 2, a connecting rod 3, a second clamping base 4, and a locking unit 5.

[0032] Reference Figure 4 The first clamping seat 2 includes a seat body 21 pivotally connected to the connecting rod 3 and a connecting pipe 22 extending from the seat body 21 and connected to the front vertical pipe 13 of the bicycle 1. The seat body 21 has a first in...

Abstract

The invention provides a bicycle folding mechanism, which is suitable for connecting a handle of a bicycle and a front vertical pipe inserted into a frame and comprises a first clamping seat, a connecting rod, a second clamping seat and a locking unit. The first clamping seat is connected with the front vertical pipe; the connecting rod comprises a first connecting part which is connected with the first clamping seat and a second connecting part; the second connecting part and the first connecting part are arranged at intervals; the second clamping seat is connected with the handle and the second connecting part and is switched between a folded state and a non-folded state; and the locking unit is pressed against the first clamping seat and the second clamping seat and forces the second clamping seat which is in the non-folded state to firmly clamp the connecting rod together with the first clamping seat. Therefore, the volume of the folded bicycle can be reduced.

Description

Technical field [0001] The invention relates to a bicycle, in particular to a bicycle folding mechanism. Background technique [0002] Generally, a folding bicycle uses a folding mechanism to fold the frame or the handle riser, thereby saving the space occupied by the storage or transportation of the bicycle. [0003] Refer to figure 1 and figure 2 , Is a conventional folding mechanism 6 for the handlebar riser of a small bicycle. The bicycle 7 includes a frame 71 including a C-clamp fixing structure 711, a front fork riser 72 passing through the front end of the frame 71, and A front wheel 73 installed on the front fork riser 72, an upper handle riser 74 connected to the front fork riser 72, and a handle tube 75 connected to the upper handle riser 74. The handle riser folding mechanism 6 includes an extension structure 61 fixed to the front fork riser 72 and a folder 62 fixed to the extension structure 61 and connected to the upper handle riser 74. [0004] When the user wants to...
