AI Technical Summary
Existing smart wheelchairs are inconvenient in height adjustment, complicated to operate, and lack stability, causing inconvenience and safety hazards to users' daily lives.
The height adjustment mechanism includes a worm gear drive and a threaded rod and nut structure. The worm drives two adjusting threaded rods to rotate synchronously. Combined with the sliding connection of the support column, it can achieve smooth lifting and precise positioning of the seat support and avoid tilting and swaying.
It enables convenient operation and synchronous control of height adjustment, ensuring that the seat support remains stable at any height, thus enhancing the user's sense of security and ease of operation.
