[0033] 4. In this solution, the retraction of the electric telescopic rod drives the connecting seat to move, which in turn drives the V-shaped linkage to move. The two guide rods ensure the stability of the connecting seat's movement. The movement of the V-shaped linkage pulls the connecting shaft to move, which in turn drives the ramp plate to rotate. The rotation of the ramp plate blocks the opening of the storage basket, preventing the wheelchair from sliding out of the basket's inlet, thus restricting the wheelchair's movement.

[0034] 5. In this solution, the V-shaped limiting strip is used to block the wheelchair's tires, thereby restricting movement. The fixing screws are used to fix the position of the V-shaped limiting strip, and the fixing screws can also be used to adjust the position of the V-shaped limiting strip on the storage basket.

[0035] 6. In this solution, the casters allow the storage basket to make initial contact with the ground after it descends. After contact, the casters allow the storage basket to continue descending. Once it descends, rubber support feet provide support, keeping the storage basket separate from the ground. Attached Figure Description
