Multi-purpose folded tricycle operating mechanism and using method

Abstract

The invention discloses a multi-purpose folded tricycle operating mechanism and a using method. The operating mechanism comprises a frame and two front wheels. Handlebars are arranged on the frame. The frame comprises two front forks, a head pipe, a sitting pipe, a cross beam pipe between the two front wheels, a girder pipe, a connecting part for connecting the cross beam pipe and the girder pipe,two folding devices and rear forks, wherein the front forks incline forwards at an angle, are parallel to each other and are vertical, and the two folding devices are arranged on the girder pipe andare opposite in folding direction. A supporting frame of a universal assistance wheel assembly is installed at the front end of the frame. The frame head pipe or the cross beam pipe and the front forks or a connecting rod for connecting the two front forks are provided with latch suites or rapid locking mechanisms correspondingly. The operating mechanism further comprises a folded vertical pipe which is connected with the two front forks. The two handlebars are provided with one connecting rod assembly with a rapid disassembling structure, or the two front forks are provided with one connecting rod assembly with a rapid disassembling structure. The operating mechanism has the advantages that the structure is safer for riders, operation is convenient, after the riding state structure is converted into the pushing state structure, the size of a whole tricycle is reduced substantially, and pushing is more flexible.

Description

technical field [0001] The invention relates to a multipurpose folding tricycle operating mechanism and a using method. Background technique [0002] Existing bicycles for mothers and babies generally turn the rear wheels to the front along the beam as the center, without auxiliary wheels, and directly still utilize the rear wheels to rotate and promote. The disadvantage of this method is: because the rear wheels cannot swing left and right, after the rear wheels are turned over to the front along the beam as the center, when using the rear wheels to rotate and promote, it is more convenient to go straight but it is not smooth when turning. In addition, the prior art also has a rack on the rear wheel to install a universal auxiliary wheel, and the bicycle becomes a tricycle after turning over 180 degrees. However, after turning over 180 degrees, the rear wheel of the bicycle is still used to carry out, because the rear wheel of the bicycle It cannot turn left and right, so ...

Problems solved by technology

The disadvantage of this method is: since the rear wheels cannot swing from side to side, after turning the rear wheels to the front along the beam as the center, when using the rear wheels to rotate, it is more convenient to go straight, but it is not smooth when turning

In addition, the prior art also has a rack on the rear wheel to install a universal auxiliary wheel, and the bicycle becomes a tricycle after turning over 180 degrees. However, after turning over 180 degrees, the rear wheel of the bicycle is still used to carry out, because the rear wheel of the bicycle It cannot turn left and right, so it is no problem to go straight after turning 180 degrees, but it is very laborious to turn and turn, and before turning the rear wheel forward 180, you must first remove the device basket from the car and put it next to it, and then you can operate it. The rear wheel is flipped 180 degrees. This process will make the user leave the guardian's sight and distance for a short time, which will be unsafe. In addition, the operation process is also very laborious and the user experience is poor.
