But the intelligent door lock body and the panel on the market are heavy and firm, are mainly suitable for the anti-theft door and the entrance door and are not suitable for the inner door. The intelligent handle door lock is a second choice of the inner door lock due to small size, simplicity and easiness in installation. The intelligent handle door lock is limited by the shape and the volume of the handle door lock, generally only has an intelligent opening system without a mechanical opening system, is definitely specified in JG/T394 and 2012 building industry standards of the people's republic of China and GA701 and 2007 public safety industry standards of the people's republic of China, and has to have an emergency unlocking function. Based on the prior art, the Chinese utility model patent publication with the publication number of "CN 207776608U" describes a convenient dual-drive push-pull handle door lock device, which can realize full-automatic opening and closing of a door lock by driving a lock body by a motor; and a manual mode can be adopted, and the door lock handle is directly pushed or pulled to realize quick locking and unlocking. The technical scheme basically meets the construction industry standard of JG/T394 and 2012 people's republic of China and the public safety industry standard of GA701 and 2007 people's republic of China.

Meanwhile, the lock body can be driven by the motor, and the driving motor rotates clockwise or anticlockwise to drive the motor rotating shaft, so that the mechanical lock head shifting piece is driven to open and close the door, and the full-automatic door lock opening and closing is realized; and a manual mode can be adopted, and the lock knob can rotate clockwise or anticlockwise after being pressed along the arrow direction to drive the motor to rotate the shaft, so that the mechanical lock shifting piece is driven to open and close the door. The applicant analyzes and considers that the technical scheme has the following defects: the transmission structure in the scheme is complex, so that the transmission structure can only be concentrated in the body coated by the panel, the scheme is inconvenient, and the cost is high. In addition, although the scheme adopts a mode of combining mechanical unlocking and intelligent unlocking, the scheme is only that a mechanical lock head plectrum is connected with the motor rotating shaft, and the lock head knob drives the mechanical lock head plectrum through the motor rotating shaft; therefore, the scheme is equivalent to connecting the motor and the mechanical driving part on the same transmission structure, so that the scheme can only avoid the emergency unlocking condition caused by the damage of the motor; but it is impossible to avoid damage or malfunction of the transmission mechanism.
