[0002] As the population ages, mobility scooters have become an important aid for many people with limited mobility. These scooters not only improve users' mobility but also enhance their independence and comfort.

[0003] The seats of traditional mobility scooters are usually fixed and cannot be adjusted in forward or backward position or angle according to the user's needs. This causes users to feel uncomfortable during long-term use, especially in different usage scenarios. Secondly, different users have different body shapes and preferences. The traditional fixed seat design cannot meet the needs of all users, which reduces the user experience. Furthermore, for the elderly and people with limited mobility, getting in and out of the vehicle is a challenge. Traditional seat designs do not take this into account, making it very inconvenient for users to enter and exit the vehicle.

[0054] The working principle of the seat adjustment mechanism of the scooter is as follows:

[0055] The operation for adjusting the front and rear position of the seat 201 is as follows:

[0056] By holding and rotating the first operating lever 303, the rotation of the first operating lever 303 drives the locking plate 304 to deflect, thereby disengaging the front fork on the locking plate 304 from the locking groove. At this time, the lock of the front and rear position of the seat 201 is released. Subsequently, force is applied to the seat 201 to move the front and rear position of the seat 201. After moving to the appropriate position, the first operating lever 303 is released. Under the action of the torsion spring 305, the first operating lever 303 is driven to return to its original position, thereby driving the locking plate 304 to return to its original position, so that the front fork on the locking plate 304 is placed back in the locking groove, thus completing the adjustment of the front and rear position of the seat 201.

[0057] The operation for adjusting the angular position of the axis of the seat 201 and the frame 1 is as follows:

[0058] The second operating rod 405 is held in the locked position by the spring 408, and the second operating rod 405 is released.
