The present disclosure discloses a storage device connected to a support portion. The storage device comprises a storage portion configured for movement relative to the support portion. The storage device further comprises a driving mechanism and a sensor unit configured to determine whether an object is present on the storage portion. The driving mechanism is configured to drive the storage portion so as to control the storage portion to move between at least an in-use state and a non-use state. The sensor unit is communicatively connected to the driving mechanism and is configured to control the driving mechanism to keep the storage portion in the in-use state when the sensor unit determines that there is an object on the storage portion.
