Detailed Description

The core of the invention is to provide a folding vehicle, so that the vehicle weight of the folding vehicle and the occupied volume after folding can be further reduced, and the portability of the folding vehicle can be further improved.

In order that those skilled in the art will better understand the disclosure, the invention will be described in further detail with reference to the accompanying drawings and specific embodiments.

The folding bicycle disclosed in the present invention, including but not limited to electric vehicles, bicycles, scooters, etc., actually, comprises a frame body including a front open ring 1 and a rear open ring 2 connected by a folding mechanism 3, and the front open ring 1 and the rear open ring 2 form a closed ring body after folding.

In the above embodiment, since the frame main body is composed of two open rings, and the two open rings form a closed ring body after being folded, compared with the prior art, the folding vehicle has only one closed ring body after being folded, so that the space occupied by the folding vehicle is effectively reduced, and meanwhile, because of the reduction of materials, the weight of the whole vehicle is also significantly reduced, so that the portability of the folding vehicle is greatly improved.

It is understood by those skilled in the art that the implementation form of the folding mechanism 3 is not limited to one, for example, in the embodiment of the present invention, the folding mechanism 3 is a telescopic joint with a locking device, the front split ring 1 is connected with the front end of the telescopic joint, the rear split ring 2 is connected with the rear end of the telescopic joint, and the locking device can adopt a currently common form, such as a positioning pin, a top bead, etc. In the present embodiment, the direction of travel of the foldable vehicle is taken as the front, so that the telescopic joint has front and rear ends, and the front open ring 1 and the rear open ring 2 are named based on the same reference.

In a specific embodiment, as shown in fig. 2, the telescopic joint comprises a set, the front end of the telescopic joint is connected with the upper interface of the front split ring 1, and the rear end of the telescopic joint is connected with the upper interface of the rear split ring 2. The telescopic joint comprises at least three sections with different sections, each section can be retracted into an adjacent larger section, so that the length of the whole telescopic joint is shortened, and when the telescopic joint is completely retracted, the bottoms of the front split ring 1 and the rear split ring 2 are just connected to form a closed ring body. Furthermore, two adjacent sections in the telescopic joint can be connected through a roller, a bearing or a sliding block, so that smooth drawing can be realized, and after the telescopic joint is stretched in place, the telescopic joint is locked by the locking device, so that the telescopic joint is prevented from rotating and loosening.

It should be noted that, in the above embodiment, since one split ring has two ends, the upper end is referred to as an upper port, and the lower port is referred to as a lower port.

The lower part of the front open ring 1 is a rotatable front fork 4, as shown in fig. 2, a front wheel 5 is arranged on the front fork 4 in a turnover way through a front wheel frame 6, a rear wheel 13 is arranged on the rear open ring 2 in a turnover way through a rear wheel frame 7, after being folded, the front wheel 5 is turned to one side of the closed ring body and is embedded in the closed ring body, and the rear wheel 13 is turned to the other side of the closed ring body and is embedded in the closed ring body, as shown in fig. 3. Of course, locking devices should be provided at the front wheels 5 and the rear wheels 13, and the locking devices can play a role in locking when the front wheels and the rear wheels are unfolded or folded, so as to prevent the front wheels and the rear wheels from loosening.

The upper portion of anterior split ring 1 penetrates handlebar assembly, handlebar assembly's bottom and front fork 4 link to each other, cooperate each other through parts such as bowl group, bearing between handlebar assembly and the anterior split ring 1, its complex concrete structure can refer to the cooperation mode of handlebar and frame in the existing bicycle, it does not repeated here to describe specifically, handlebar assembly specifically includes handlebar riser 8 and sets up the handle 9 at 8 tops of handlebar riser, as shown in fig. 2, and this handlebar riser 8 is the flexible pipe that has locking means, locking means on the handlebar riser 8 is preferred for locating pin or top ball, of course, also can be screw or quick detach spanner etc..

Compare in prior art, folding car in above-mentioned embodiment handlebar only need drive front fork 4 and rotate when turning to, and need not to drive whole anterior split ring 1 and rotate, and this makes turning to of vehicle more merrily and lightheartedly laborsaving, and customer's travelling comfort experience is better.

Furthermore, the outer end of the handle 9 may also be bent towards the inside of the foldable wagon, after bending, parallel to the plane of the closed loop, after folding, the handle 9 forms a handle for the user to lift the foldable wagon, as shown in fig. 3.
