Description

Technical Field

[0001] This utility model relates to the field of scooters, and in particular to a foldable scooter frame. Background Technology

[0002] Scooters are popular in Japan and Southeast Asia due to their ease of use and ease of learning. As a result, the scooter craze has gradually spread to the domestic market. Scooters are very lightweight, generally weighing less than 3kg, and can be folded up or unfolded in 30 seconds when stored. Because of their moderate speed, ease of use, and braking system, scooters are generally not prone to causing falls when used for daily commuting or casual recreation.

[0003] In existing scooters, the folding structure is mostly located at the bottom of the handlebars. This reduces the overall height of the device when folded. However, the scooter frame generally varies in length, and longer frames are inconvenient to carry. Therefore, to make it easier to carry after folding the handlebars, it is necessary to consider folding the frame as well, thereby shortening the frame size for easier carrying. Thus, a foldable scooter frame is proposed. Utility Model Content
