Description

Technical Field

[0001] The utility model relates to the field of door locks, in particular to an intelligent detection door lock. Background Art

[0002] General door locks are divided into inner handles and outer handles. Currently, smart door locks on the market are all set with touch password unlocking, fingerprint unlocking or face recognition unlocking on the outer handle, which are convenient for users to enter the house from the outside. At present, ordinary inner handles on the market are mainly unlocked by mechanical structure. People in the house can unlock and go out by turning the inner handle. Users cannot know the situation of people going out. For example: elderly people with Alzheimer's disease, young children or pets in the house can simply turn the inner handle to open the door and leave the house. In this case, users cannot timely know the information that they turn the inner handle to leave the house, which will bring inconvenience to life. Summary of the invention

[0003] The technical problem to be solved by the utility model is to provide an intelligent detection door lock, which can instantly send out an electric signal when the inner handle is turned to open the door, so that the user can obtain the unlocking and use status of the door lock in time.

[0004] The technical solution adopted by the utility model to solve the above technical problems is:

[0005] An intelligent detection door lock comprises a shell and an inner handle, wherein the inner handle is rotatably mounted on the shell, an inner handle rotation detection mechanism is arranged in the shell, the inner handle rotation detection mechanism comprises a magnet, a PCBA board fixedly arranged in the shell, a driving power supply and a communication board, the communication board is electrically connected to the PCBA board, the PCBA board is electrically connected to the driving power supply, a Hall element is electrically connected to the PCBA board, the magnet is fixedly connected to the inner handle, and when the inner handle drives the magnet to rotate, the Hall element generates an electrical signal due to the rotation of the magnet.

[0006] Preferably, a rotating shaft is fixedly connected to the inner handle, the rotating shaft is inserted into the shell, a rotating plate is fixedly arranged on the rotating shaft, and the magnetic steel is fixedly arranged on the rotating plate.

[0007] Preferably, a touch panel is provided on the inner handle, a handle decoration plate is mounted on the touch panel, and the touch panel is electrically connected to the PCBA board.

[0008] Preferably, a reverse locking knob is provided on the shell, and the reverse locking knob is fixedly connected to one end of the reverse locking shaft, and the other end of the reverse locking shaft passes through the shell and is fixedly connected to the locking member.

[0009] Preferably, a battery compartment is provided on the shell, the driving power source is arranged in the battery compartment, and a detachable battery cover is provided on the battery compartment.

[0010] Compared with the prior art, the advantage of the utility model is that an inner handle rotation detection mechanism is arranged in the shell where the inner handle is installed. When the inner handle is rotated, the inner handle rotation detection mechanism generates an electrical signal, and whether the inner handle is rotated can be identified by the generated electrical signal data; a touch panel is arranged on the inner handle, and an electrical signal is generated only when a person's hand is placed on the inner handle. When a pet turns the inner handle, the touch panel will not generate an electrical signal, thereby distinguishing whether it is a person or an animal that is turning the inner handle; by analyzing different electrical signals, the unlocking and use of the intelligent detection door lock can be judged, and the going out of the people and pets in the house can be timely understood.

[0016] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0017] As shown in the figure,

[0018] A smart detection door lock comprises a shell 3 and an inner handle 2, the inner handle 2 is rotatably mounted on the shell 3, an inner handle rotation detection mechanism is arranged in the shell 3, the inner handle rotation detection mechanism comprises a magnetic steel 6, a PCBA board 4 fixedly arranged in the shell 3, a driving power supply 5 and a communication board 1, the communication board 1 is electrically connected to the PCBA board 4, the communication board 1 uploads the collected data to a shared data platform or a mobile phone APP, and the user can instantly receive the status of the smart detection door lock through the shared data platform or the mobile phone APP, the PCBA board 4 is electrically connected to the driving power supply 5, a Hall element 7 is electrically connected to the PCBA board 4, a rotating shaft 9 is fixedly connected to the inner handle 2, the rotating shaft 9 is inserted into the shell 3, and the rotating shaft 9 A rotating plate 8 is fixedly arranged on the upper part, and a magnet 6 is fixedly arranged on the rotating plate 8. When the inner handle 2 drives the magnet 6 to rotate, the Hall element 7 generates an electrical signal due to the rotation of the magnet 6. A touch panel 10 is arranged on the inner handle 2, and a handle decorative plate 11 is installed on the touch panel 10. The touch panel 10 is electrically connected to the PCBA board 4. An anti-lock knob 12 is arranged on the shell 3. The anti-lock knob 12 is fixedly connected to one end of the anti-lock shaft 13, and the other end of the anti-lock shaft 13 passes through the shell 3 and is fixedly connected to a locking member (not marked in the figure). By rotating the anti-lock knob 12, the anti-locking and opening of the door lock can be intelligently detected. A battery compartment is arranged on the shell 3, and a driving power supply 5 is arranged in the battery compartment. A detachable battery cover 14 is arranged on the battery compartment.

[0019] In the above embodiment, the connection structure between the anti-lock shaft 13 and the locking member is an existing conventional structure in the door lock, and the signal detection and transmission between the Hall element 7, the PCBA board 4, the communication board 1 and the touch panel 10 can be achieved through the existing technology.

[0020] The detection principle of the intelligent detection door lock of the utility model is: when the inner handle 2 is turned, the rotating shaft 9 is driven to rotate, so that the magnetic steel 6 fixed on the rotating plate 8 starts to rotate. During the rotation of the magnetic steel 6, the Hall element 7 generates an electrical signal due to the change in the distance between the Hall element 7 and the magnetic steel 6; when a person puts his hand on the inner handle 2, the touch pad 10 in the inner handle 2 will detect the electrical signal. When a person puts his hand on the inner handle 2 and turns the inner handle 2 to open the door lock, the Hall element 7 and the touch pad 10 detect the electrical signal at the same time; when a pet puts its paw on the inner handle 2 and turns the inner handle 2 to open the door lock, the Hall element 7 detects the electrical signal, and the touch pad 10 does not detect the electrical signal. The user can understand the unlocking and use of the intelligent detection door lock by viewing the data information on the shared data platform or the mobile phone APP, and timely understand the going out of the people and pets in the house.

[0021] The protection scope of the present invention includes but is not limited to the above embodiments. The protection scope of the present invention shall be based on the claims. Any replacement, deformation, and improvement of the technology that can be easily thought of by technicians in this field shall fall within the protection scope of the present invention.
