The present disclosure discloses electrically-operated inward-swing double doors and inward-swing door driving devices thereof. Each inward-swing door driving device includes a sector gear in coaxial transmission with a door shaft of the inward-swing door, a driving mechanism used for driving the sector gear to rotate, and an unlocking mechanism. The driving mechanism includes a motor gear and a motor driving the motor gear to rotate. The unlocking mechanism includes a cylinder, a cylinder push rod extending out of the cylinder, and a lock located at the end portion of the cylinder push rod. The tail end of the lock is in transmission connection with a wheel axle of the motor gear. The lock is provided with a lock rotating shaft for rotating horizontally around the lock. The lock rotating shaft is provided with an elastic element for applying twisting resilience force to the lock. When the cylinder is unlocked for air feeding, the cylinder push rod pushes the lock to rotate, so that the motor gear and the sector gear mesh with each other and twist the elastic element. When the cylinder is unlocked for air discharge, the lock rotates back under the action of the twisting resilience force of the elastic element and drives the motor gear and the sector gear to demesh. The present disclosure is more reliable in locking, good in mechanism stability and small in volume, and has a safe and reliable anti-pinch function.
