Folding electric tricycle

Abstract

The invention discloses a folding electric tricycle which comprises an electric driving system, a braking system, a front wheel steering mechanism with a front wheel, a rear vehicle frame with two rear wheels, and a cushion branch pipe which is provided with a cushion and can be overturned relative to the rear vehicle frame. The front wheel steering mechanism is pivoted to ends of two parallel connecting rods; the other ends of the two connecting rods, one end of the rear vehicle frame and a pull rod pivoted to the cushion branch pipe are pivoted to a driving part, the driving part is locked and released through a locking and release mechanism, the locking and release mechanism comprises a locking part pivoted to the rear vehicle frame and a clamping groove which is formed in the driving part and matched with the locking part, and the locking part is connected with a returning mechanism and a driving mechanism for driving the locking part to be overturned. The button type locking and release mechanism is adopted, release of the driving part and automatic locking of the driving part can be implemented quickly, and folding and unfolding operations are simple; by combination with a combined type limiting mechanism between the connecting rods, structure fixing stability of the whole tricycle is effectively ensured, and safety is improved.

Description

technical field [0001] The invention relates to a tricycle, in particular to a folding electric 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 an...

Problems solved by technology

[0005] But existing tricycle volume is big, is unfavorable for placement, so also have to design a part foldable electric tricycle on the market, as application number is 2013800540944 and application number is the Chinese patent application of 2009101311581, but these foldable electric tricycles still have some obvious disadvantages defect,

[0006] For example, the folding electric 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. Due to the general structure of the electric tricycle Large and therefore inconvenient to transport

[0007] 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

[0008] In addition, 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, with many processes, time-consuming and labor-intensive, and poor operability

[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.
