Embodiment 1

[0051] As shown in Figure 1, Figure 2 and Figure 3, the rear end of the front pedal 2, the front end of the rear pedal 3 and the middle part of the beam 1 are jointly hinged on the same hinge shaft 4, and the front end of the locking device A1 is connected to the front The middle part of the pedal 2 is hinged to the hinge pin 6 , and the rear end of the locking device A1 is hinged to the hinge pin 7 with the hinge ear 77 provided on the middle part of the rear pedal 3 . The folding vehicle frame of the present invention is a part of the folding vehicle. When the folding vehicle is assembled into a complete vehicle, the front end of the crossbeam 1 is foldably connected to the rearward and downward extension tube of the steering mechanism C; the rear end of the crossbeam 1 is connected to the The axle of rear wheel D is fixedly connected. The locking device A1 in the locked state limits the relative position between the front and rear pedals, so that the angle between the front...

Embodiment 2

[0059] As shown in Figures 10 to 13, the overall structure of the folding frame of this embodiment is the same as that of Embodiment 1 of the folding frame, and the rear end of the front pedal 2, the front end of the rear pedal 3, and the middle part of the beam 1 are jointly hinged at three places. Between the same hinge shaft 4, the front pedal 2 and the rear pedal 3, a locking device for controlling the angle change between the front pedal 2 and the rear pedal 3 is provided. The front end of the crossbeam 1 is also foldably connected to the rearward and downward extension tube of the steering mechanism C; the rear end of the crossbeam 1 is also fixedly connected to the axle of the rear wheel D. The difference is that the structure of the locking device A2 in Embodiment 2 is different from that of the locking device A1 in Embodiment 1. The locking device A2 is composed of a crankshaft linkage mechanism that is hinged with the front pedal 2 and the rear pedal 3 at the front an...

Embodiment 3

[0065] As shown in Figures 18 to 20, the overall structure of the foldable frame of this embodiment is the same as that of foldable frame embodiment 1 and foldable frame embodiment 2, both of which are the rear end of the front pedal 2, the front end of the rear pedal 3 and the beam. Three places in the middle of 1 are jointly hinged on the same hinge shaft 4, and a locking device for controlling the angle change between the front pedal 2 and the rear pedal 3 is provided between the front pedal 2 and the rear pedal 3. The front end of the crossbeam 1 is also foldably connected to the rearward and downward extension tube of the steering mechanism C; the rear end of the crossbeam 1 is also fixedly connected to the axle of the rear wheel D. The difference is that the locking device A3 in this embodiment 3 is different in structure from the locking devices A1 and A2 in the embodiment 1 and embodiment 2, and the locking device A3 is composed of a hook fixed on the front pedal 2 and ...

Abstract

The invention discloses a folding frame, comprising a front pedal (2), a back pedal (3), a cross beam (1), and a lock device controlling the variations of the included angle between the front pedal (2) and the back pedal (3). The rear end of the front pedal (2) and the front end of the back pedal (3) are hinged with the middle section of the cross beam (1); the front part of the lock device is connected with the front frame (2), and the rear part of the lock device is connected with the back frame (2). The invention has the advantages of simple operation in folding or unfolding, high speed, compact structure, small volume, light weight, and convenient carrying after being entirely folded.

Description

technical field [0001] The invention relates to a vehicle frame for bicycles, scooter and other vehicles, in particular to a folding vehicle frame for folding vehicles such as folding bicycles and folding scooters. Background technique [0002] In recent years, various folding bicycles, such as folding bicycles and folding scooters, have been loved by more and more people. Before and after transferring to the bus or subway, if there is a folding car that can travel short distances, and is small in size after folding, it will bring a lot of convenience to people's travel; Due to the frequent loss of the car, people who carry their bicycles up and down the stairs every day need a small and portable folding bike. But more people can't help but feel a little regretful, because among the various folding bikes that can be selected, it is difficult to find a folding bike that is really compact, easy to carry, and practical. One of the reasons is that the structure of the folding ...
