TECHNICAL FIELD

[0002] As a common motor vehicle, the structural design of motorcycle mainly focuses on driving stability and power performance. Traditional motorcycles adopt rigid frame structure, and each component is connected through welding or bolt fixation, which has high structural strength and driving safety. This design performs excellently in conventional use scenarios and can meet the needs of daily commuting and long-distance riding. However, its non-deformable characteristics have obvious limitations in special scenarios, especially when transportation or storage is needed. The fixed size of the whole vehicle occupies a large space, causing many inconveniences to users.

[0003] The current motorcycle design has significant space adaptability defects: first, the non-collapsible rigid structure requires standard parking space for transportation, which cannot meet the loading needs of small vehicles (such as car trunks, residential elevators, etc.); second, the fixed-size vehicle body needs a special parking area when parked for a long time, resulting in low urban space utilization; third, the traditional structure increases the operation difficulty when temporary transportation is needed in special scenarios (such as outdoor exploration, emergency rescue). These defects restrict the expansion of motorcycle use scenarios, and there is an urgent need to develop a foldable motorcycle solution with space compression capability. Therefore, we propose a collapsible portable motorcycle. UTILITY MODEL CONTENT
