Problems solved by technology

Three-wheeled scooters are constantly updated and improved during the development process, resulting in various designs and developing corresponding products suitable for different age groups. However, these three-wheeled scooters have the following deficiencies during use: 1. The existing three-wheeled scooter is provided with a folding device between the connecting seat and the left and right foot pipes in order to facilitate the transportation, packaging volume and storage space. However, the existing folding device has a complex structure, large matching clearance, poor reliability, and is easy to deform and damage. ; Second, there is no buffer and vibration damping part between the connecting seat and the left and right pedal tubes, which causes high noise, fast wear and short service life

For this reason, many manufacturers and people of insight have carried out research and development on the above-mentioned problems, but have not found a more reasonable solution so far.
