Embodiment 1

[0045] As shown in Figures 1 and 2, the rear end of the front frame 2, the front end of the rear frame 3, and the middle part of the pedal 1 are jointly hinged on the same hinge shaft 4, and the front end of the locking device A1 is connected to the front end of the front frame. The axial middle part of the frame 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 arranged on the axial middle part of the rear vehicle frame 3; One part, when assembled into a complete folding vehicle, the front end of the front frame 2 is foldably connected to the rearward and downward extension tube of the steering mechanism C or is fixedly connected to the axle of the front wheel E; the rear frame 3 The rear end is fixedly connected with the axle of rear wheel D. The locking device A1 in the locked state limits the relative position between the front and rear frames, so that the angle between the front frame 2 and the rea...

Embodiment 2

[0053] As shown in Fig. 8 and Fig. 9, the embodiment 2 of the folding vehicle frame of the present invention is the same as the overall structure of the folding vehicle frame embodiment 1 in this embodiment, and both are the rear end of the front vehicle frame 2 and the rear vehicle frame. The front end of 3 and the middle part of pedal 1 are jointly hinged on the same hinge shaft 4, and there are locks between the front frame 2 and the rear frame 3 to control the angle change between the front frame 2 and the rear frame 3 device. The front end of the front frame 2 is also foldably connected to the rearward and downward extension tube of the steering mechanism C; the rear end of the rear frame 3 is fixedly connected to the axle of the rear wheel D. The difference lies in that the structure of the locking device A2 in the second embodiment is different from that of the locking device A1 in the first embodiment, and the connection method between the locking device A2 and the fro...

Embodiment 3

[0058] As shown in Fig. 14 and Fig. 15, the overall structure of the foldable frame of this embodiment is the same as that of the foldable frame embodiment 1 and the foldable frame embodiment 2, both of which are the rear end of the front frame 2 and the front end of the rear frame 3. The three places in the middle of the pedal 1 are jointly hinged on the same hinge shaft 4, and a locking device for controlling the angle change between the front frame 2 and the rear frame 3 is provided between the front frame 2 and the rear frame 3. The front end of the front frame 2 is also foldably connected to the rearward and downward extension tube of the steering mechanism C; the rear end of the rear frame 3 is also fixedly connected to the axle of the rear wheel D. The difference is that the structure of the locking device A3 in the third embodiment is different from that of the locking devices A1 and A2 in the first and second embodiments, and the connection between the locking device A...

Abstract

The invention discloses a folded vehicle frame, comprising front vehicle frame (2) and back vehicle frame (3) and pedal (1). The invention also comprises a locking device for controlling the included angle variation of the front vehicle frame (2) and the back vehicle frame (3). The back end of the front vehicle frame (2) and the front end of the back vehicle frame (3) and the middle of the pedal (1) are jointed together on one cardinal axis (4). The fore part of the locking device is connected with the front vehicle frame (2). The front end of the front vehicle frame (2) is folding type connected with the extension pipe at the inferior of the steering gear (C) or permanently connected with the axle of the front wheel (E). The back end of the back vehicle frame (3) is permanently connectedwith the axle of the back wheel (D). The folding and unfolding process of the folded vehicle frame is simple and the speed is quick, the construct after folding is compact and the volume is small andthe weight is light. The folded vehicle frame can be carried conveniently.

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 favored by more and more people. Before and after changing buses or subways, 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 when it is carried on the bus or subway without taking up passenger space; Lost the car, and people who carry their bicycles up and down the stairs every day need a small, 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 ...
