Description

Technical Field

[0001] The utility model relates to the technical field of mobility scooters, in particular to a seat cushion assembly of a mobility scooter with folding armrests. Background Art

[0002] An electric scooter is a vehicle that uses an onboard battery to provide power to drive a joystick to control the motor output, which then drives the rear wheel through a transmission mechanism. The rear wheel then drives the front wheel to rotate synchronously to achieve travel. Although its speed is low and the riding distance is limited, it can improve people's travel efficiency and is green and environmentally friendly. Electric scooters include various forms of short-distance transportation such as bicycles and scooters, and there is a huge market demand for them.

[0003] The seat armrests of current mobility scooters are not convenient to fold after the scooter is folded, and the current backrest and armrest linkage mechanism, when the armrest is rotated to the unfolded position along with the backrest, the armrest can no longer be rotated independently, so the armrest will block the side passage of the seat, making it inconvenient for users with limited mobility to get on and off the vehicle from the side. Utility Model Content

[0004] In view of the defects in the prior art, the purpose of the utility model is to provide a seat cushion assembly for a mobility scooter with folding armrests, which has a foldable function for use on a mobility scooter, greatly reducing the volume of the mobility scooter after folding; the armrests can be rotated and adjusted individually to facilitate users to get on and off the vehicle.
