Electric folding tricycle

Abstract

The invention discloses an electric folding tricycle, which comprises an electric driving system, a brake system, a front wheel steering mechanism, a back vehicle frame and a seat cushion support pipe, wherein the front wheel steering mechanism is provided with a front wheel; the back vehicle frame is provided with back wheels; the seat cushion support pipe is provided with a seat cushion and can be turned relative to the back vehicle frame; two parallel connecting rods are connected onto the front wheel steering mechanism through a pivot; a first electric driving mechanism used for driving a connecting rod to rotate is arranged between the front wheel steering mechanism and the connecting rod; the two connecting rods, the back vehicle frame and a pull rod connected with the seat cushion support pipe through a pivot are respectively connected with a driving element through pivots; the driving element is locked and released through a locking and releasing mechanism; the locking and releasing mechanism comprises a locking element connected with the back vehicle frame through a pivot and a clamp groove formed in the driving element; the locking element is connected with a manual driving mechanism, a second electric driving mechanism and a reset mechanism; the manual driving mechanism drives the locking element to turn. The electric folding tricycle has the advantages that the electric folding and unfolding can be easily realized, so that the folding and unfolding efficiency can be greatly improved; the use is more convenient; in addition, the manual operation and the electric operation are combined; the operability is high; the folding modes are various.

Description

technical field [0001] The invention relates to a tricycle, in particular to an electric folding tricycle. Background technique [0002] With the continuous improvement of people's quality of life, the demand for energy saving, environmental protection, portability, diversity, complementarity and aesthetics of vehicles is becoming more and more urgent. [0003] As an important energy source with environmental protection, cleanliness and high conversion rate, electricity is widely used in production and life. As a green sunrise industry, electric vehicles are energy-saving, environmentally friendly, convenient to travel, and relatively low-cost medium-to-short-distance transportation. , has a large mass base and market prospects. [0004] The tricycle, as the name suggests, includes three-wheeled electric vehicles or bicycles or automobiles. Compared with two-wheeled vehicles, one more wheel is in contact with the ground, and it has a very unique stability advantage on wet a...

Problems solved by technology

[0005] However, the existing folding tricycles are basically folded manually, and because the entire folding mechanism of the above-mentioned patent is relatively complicated, multiple parts need to be operated to realize folding and unfolding, so the operation of folding and unfolding is cumbersome and involves many processes. Time-consuming and labor-intensive, poor operability, and due to the complicated folding structure, it is difficult to perform electric folding, so there are few folding tricycles that can be electrically folded

[0006] But existing tricycle volume is big, is unfavorable for placement, so also have to design a part of collapsible tricycle on the market, as application number is 2013800540944 and application number is the Chinese patent application of 2009101311581, but these collapsible tricycles also have some obvious defects,

[0007] For example, the folding tricycle in the above two patent applications, after folding, the front wheel and the rear wheel form a certain angle or have a height difference between the front wheel and the rear wheel, so it is inconvenient to push it in the folded state, because the general structure of the electric tricycle is large , so it is inconvenient to carry

[0008] At the same time, as in the patent application of 2013800540944, the overall structure of the tricycle is complicated. After folding, the occupied space is still large, and because there is no effective support structure, it is not easy to place. Of course, there are other folding structures, and the space between the parts The degree of integration and coordination is not high, resulting in unsatisfactory folding effect

[0009] Finally, due to the existence of the folding mechanism, multiple parts in the folding mechanism often have a certain degree of mobility. Therefore, in the unfolded state, a certain fixed structure is required to ensure that the parts will not move suddenly and cause safety accidents.
