[0021] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0022] In the following embodiments, the same or similar reference numerals denote the same or similar components or components having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0023] In the description of this invention, it should be understood that terms such as center, longitudinal, transverse, length, width, thickness, upper, lower, front, rear, left, right, vertical, horizontal, top, bottom, inner, outer, clockwise, counterclockwise, etc., indicating orientation or positional relationships, are based on the orientation or positional relationships shown in the accompanying drawings and are only for the convenience of describing and simplifying the description of this invention; therefore, they should not be construed as limiting this invention. Furthermore, terms such as first, second, etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features shown. In the description of this invention, unless otherwise expressly specified and limited, terms such as installation, connection, linking, etc., should be interpreted broadly, and those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0024] Reference Figures 1 to 6 A networked door lock with a built-in 4G gateway includes a first lock body 100 and a second lock body 200. The first lock body 100 is installed on the door, and the second lock body 200 is installed on the door frame at a position corresponding to the first lock body 100. The second lock body 200 houses a control circuit section 210 and a power supply section. The control circuit section 210 houses a gateway module. Compared with existing technologies, this invention features an innovative design for the networked door lock structure, placing the control part of the door lock within the door frame, increasing the difficulty of damaging the networked door lock, and significantly improving the door lock's protective performance.

[0025] In this invention, the door lock function is achieved through the cooperation of the unlocking component 250 and the bolt 110, with the following specific structure: The first lock body 100 is equipped with the bolt 110, and the second lock body 200 is provided with a lock hole 201 for the bolt 110 to extend into. The bolt 110 is provided with a locking groove 111. The second lock body 200 is equipped with an unlocking motor 240, which is connected to the unlocking component 250. The unlocking component 250 has an unlocking stop 251 on one side and a locking pin 252 on the other side. When the door lock is locked, the locking pin 252 engages with the locking groove 111. When the door lock is unlocked, the unlocking component 250 rotates, and the unlocking stop 251 pushes the bolt 110 out of the lock hole 201.

[0026] The unlocking component 250 can be approximately C-shaped, and the latch 110 is surrounded by the unlocking component 250, resulting in a compact overall structure suitable for doors with a small latch 110. Alternatively, the unlocking component 250 can be approximately O-shaped, and correspondingly, the locking groove 111 penetrates the latch 110, making the latch 110 hook-shaped. This structure is suitable for doors with a high-strength latch 110, and its locking performance is more reliable than that of a C-shaped latch.

[0027] Furthermore, the second lock body 200 is equipped with a contact transmission module, which is connected to a first contact head 261, which protrudes from the surface of the second lock body 200. The first lock body 100 is equipped with an identification module 120, which is connected to a second contact head 121, which protrudes from the surface of the first lock body 100 and faces the first contact head 261. This design allows the first lock body 100 to have unlocking methods other than key unlocking and wireless control unlocking. Preferably, the identification module 120 can be an NFC module or an IC module. This type of identification module does not need to be exposed, allowing the appearance of the first lock body 100 to be designed to be consistent with traditional security door locks, making the networked door lock more concealed and increasing the difficulty of cracking the lock.

[0028] Furthermore, the power supply unit includes a daily power supply module 220 and an emergency power supply module 230. The daily power supply module is connected to mains power to ensure a stable power supply for the door lock, enabling long-term use without frequent battery replacements. The emergency power supply module 230 includes a rechargeable battery, which can be used for emergency power supply during power outages to ensure normal operation of the door lock. This dual power supply design allows the door lock to operate stably for extended periods.

[0029] In addition, to improve the security performance of the door lock, the second lock body 200 is equipped with a sound sensor 270, which can detect whether the door lock or the door body has been damaged, so as to remind the homeowner.

[0030] This invention can be used in various ways. It can be used as a smart lock: the second lock body 200 is used in conjunction with the first lock body 100 to unlock without a key, suitable for daily use; it can also be used as a traditional lock: the first lock body 100 is closed and only the second lock body 200 is used, suitable for special situations such as long-term power outages when the second lock body 200 cannot be used for a long time; it can also be used in combination with both: a traditional anti-theft door lock is equipped with a locking cylinder 130 with a locking function. Combining the locking function of the locking cylinder 130 of the first lock body 100 and the second lock body 200 allows the door lock to be locked in multiple ways, improving the door lock's protective performance.

[0031] The scope of protection of this invention includes, but is not limited to, the above embodiments. The scope of protection of this invention is defined by the claims. Any substitutions, modifications, or improvements to this technology that are easily conceived by those skilled in the art fall within the scope of protection of this invention.
