Embodiment Construction
[0022] The cart has two states, folded state and unfolded state.
[0023] collapsed state (see image 3 , 4 , 5, 9) It is easy to carry and store, and the saddle 6 in the folded state has a certain storage capacity, which can be used to store items that cannot be squeezed such as notebooks. The strap buckles 10 on both sides of the saddle 6 are connected to the straps The trolley can be carried on the back.
[0024] The process of transforming the folded state of the trolley into the unfolded state is as follows: rotate the front wheel arm 1 to the dead point around the rotating joint connecting it with the base 4, and then unfold the rotating shaft between the upper and lower arms of the front wheel arm 1 to the position between the upper and lower arms. The planes are in contact, and the two front wheels are placed on the ground; after the inner tube of the rear wheel arm 2 is pulled out from the outer tube and fixed with a pin, the rear wheel arm 2 is rotated around its r...

The invention relates to an electric three-wheeled folding cart which can be folded to a size of a backpack. The electric three-wheeled folding cart has a small size (as big as a hiking bag) after being folded, has a light weight (15 kilos), is multipurpose, can be ridden for 20 km, can carry a backpack during an excursion, and can carry a basket when an old person buys vegetables. The electric three-wheeled folding cart is characterized in that each of two front wheels is driven by an independent driving motor; turning is realized through speed difference of the two front wheels; a rear wheel is a freewheel which is unpowered and controlled by the speed difference of the front wheels in the direction; and front wheel arms adopt folding designs, a rear wheel arm adopts a telescopic structure, a saddle is hollow and can store objects, and the saddle can be equipped with straps so as to be carried on the back. The electric three-wheeled folding cart comprises the front wheel arms (1), the rear wheel arm (2), a support rod (3), a connecting base (4), an operating handle (5), the saddle (6) and the like.
Description
technical field [0001] The invention relates to a three-wheel folding electric trolley that can be folded into the size of a backpack. It has small volume after folding (the size of a mountaineering bag), light weight (15 kg), and is multi-purpose. It can be used for transportation within 20km, carry backpacks for short trips, or carry baskets for the elderly when shopping for vegetables. Background technique [0002] Electric vehicles are commonly used means of transportation at present, but traditional electric vehicles may be huge in size and weight, and require special parking spaces for storage. And because of the two-wheel structure, there are certain potential safety hazards (falling down at low speed, etc.). At the same time, traffic jams are more common in urban environments, and the distribution of stations is also unreasonable (for example, the final destination in the station is far away). An easy-to-carry short-distance light transportation tool has its existen...
