This makes the connection between the vertical tube of the scooter and the front fork appear soft and the rigidity is not good enough, resulting in the rigidity of the entire body of the scooter is not good
The soft connection between the stem tube and the front fork will also affect the efficiency of the steering control of the handlebar
[0003] Chinese patent CN201520363103.4 discloses an "electric scooter". Its vertical tube 3 is slender and weak, which has a certain adverse effect on the stability and safety of riding.
When the scooter is folded, the entire standpipe is lowered, and the front wheel will be lifted, which cannot control the entire body height after folding to a small value
[0004] Another example is the Chinese patent CN201420631087.8 which discloses a "folding bracket positioning device and a folding electric scooter". image 3 As shown, but when folded, the front fork tube 1 will fall to the rear side, and the front wheel will be lifted to a very high position, so the volume after folding is still relatively large

[0061] Figure 13-14 Shown is the fourth embodiment of the folding bike of the present invention. Most of the features of this embodiment are the same as those of Embodiment 2. The difference is that during the folding process of this embodiment, the connecting seat 6 does not need to slide up and down along the vertical tube 4, so the aforementioned lock The tightening device can be a matching structure of screws and nuts. In addition, a transverse hinge shaft is arranged in the middle of the support rod 5 , and a switch device 57 is provided at the horizontal hinge shaft to lock or release the upper part 55 of the support rod and the lower part 56 of the support rod. In the process of folding and storing, first open the switch device 57, at this time, the upper part 55 of the support rod and the lower part 56 of the support rod can freely rotate relative to each other, and the standpipe 4 is pulled back, and the standpipe 4 falls in the direction of the rear wheel, so as to ...

Abstract

The invention discloses a folded trolley. The front end of a trolley beam is fixed to a head tube. A steering component is hinged to a vertical pipe through a transverse hinge shaft. The upper end of a supporting rod is rotationally connected to the vertical pipe through a connecting seat. The lower end of the supporting rod is hinged to a trolley body. A steering mechanism of the folded trolley is high in rigidity, stable and reliable and can be folded rapidly, and meanwhile, the folded trolley is quite small in size and easy to carry and store after being folded.

Description

technical field [0001] The invention relates to a vehicle structure, in particular to a foldable vehicle structure. Background technique [0002] Scooters are all the rage because of their lightness and ease of use. Usually scooters have longer handlebar stems, partly because the wheel diameters of scooters are generally smaller, but also because riders often need to stand on the scooter to use it, so it is necessary to ensure that there is a longer stem. This makes the connection between the standpipe of the scooter and the front fork seem soft and the rigidity is not good enough, resulting in the rigidity of the entire body of the scooter is also not good. The soft connection between the stem tube and the front fork will also affect the efficiency of the steering control of the handlebar. [0003] Chinese patent CN201520363103.4 discloses an "electric scooter", and its vertical tube 3 is slender and weak, which has a certain adverse effect on the stability and safety of ...
