[0002] With the popularization of smart homes, smart locks have gradually become an important part of home security due to their convenience and security. However, the emergency power supply of smart locks in the event of a power outage still has certain shortcomings. Currently, some smart lock motherboards are designed to support temporary charging via wired charging interfaces (such as USB Type-C, Micro USB, etc.) and by connecting to an external power source (such as a power bank or mobile phone) with a compatible charging cable to cope with sudden power outages. However, in practical applications, users often face the following problems: poor interface compatibility, users may not be able to quickly find a matching data cable in an emergency, resulting in power supply delays, affecting the user experience and even safety hazards; inconvenient operation, existing interfaces are usually located inside the lock body or in concealed locations, making it difficult for users to find a matching charging cable and increasing the complexity of emergency charging; insufficient scenario adaptability, existing technologies do not consider the diversity of emergency power sources carried by users, resulting in the need to equip a variety of charging cables to meet the charging needs of smart locks, exacerbating the risk of functional failure in power outage scenarios. Based on the above problems, this application proposes a smart lock with a self-contained charging cable that enables fast charging and more convenient operation in emergency situations.

[0006] The present invention is further configured such that: the positioning component surrounds the positioning area along the circumference of the opening, and a guide plate extends from the tail end of the positioning area, and a detachable cover plate is provided above the positioning area.
[0007] The present invention is further configured such that: the cover plate is made of rubber material and includes a buckle plate and a buckle block, the buckle block is fixedly assembled on the inner wall of the slope area, and the buckle plate covers the opening.
[0008] The present invention is further configured such that: the charging cable extends into the sloping area located at the lower end of the panel base, and the opening is located at the tail end of the sloping area.
[0009] By adopting the above technical solution
[0010] 1. Emergency power supply is guaranteed. In the event of a sudden power outage or battery depletion, users can directly power the smart lock with a portable power bank or mobile phone to avoid lock failure due to power outage, ensure continuous operation of the door lock, and improve the security of home / commercial premises.
[0011] 2. Enables emergency unlocking support. Even after the built-in battery is fully discharged, users can still unlock the door using temporary power from an external device, solving the need for entry and exit in emergency situations.
[0012] 3. Improved user convenience: The standardized data cable is compatible with users' existing mobile device charging cables, eliminating the need for special tools and lowering the barrier to entry. Attached Figure Description

[0018] Reference Figures 1 to 4 The embodiments of this utility model will be further described below.
[0019] A wired reverse charging smart lock includes a main lock plate 1 and a mounting lock plate 2. The main lock plate 1 is bent downwards at both ends to form a bridge shape. It includes a panel base 10 and a removable panel cover 11. The panel base 10 has an assembly cavity, which is divided into a flat area 110 and ramp areas 111 located at both ends of the flat area 110. A main circuit control board 3 is assembled in the flat area 110. A charging cable 4 is provided on the main circuit control board 3. The charging cable 4 extends into any ramp area 111. An opening 112 for the charging cable 4 to pass through is provided at any displacement of the inner wall of the ramp area 111. A removable cover 5 is provided at the opening 112. A limiting component 6 for limiting the charging cable 4 is provided at the connection between the flat area 110 and the ramp area 111. A positioning component 7 for limiting the charging cable 4 is provided at the opening 112 of the ramp area 111.
[0020] The limiting component 6 includes at least one limiting post, which includes a post body 60 and a limiting piece 61. The post body 60 has a screw hole for bolt assembly, and the limiting piece 61 has a recessed slot 62. After the charging cable 4 is inserted into the slot 62, the bolt is installed in the post body 60, thus limiting the charging cable 4 within the slot 62. The positioning component 7 surrounds the opening 112 to form a positioning area 70, and a guide plate 71 extends from the tail end of the positioning area 70. A removable cover plate 72 is provided above the positioning area 70. The cover plate 72 is made of rubber material and includes a buckle plate 50 and a buckle block 51. The buckle block 51 is fixedly installed on the inner wall of the ramp area 111, and the buckle plate 50 covers the opening 112. The charging cable 4 extends into the ramp area 111 located at the lower end of the panel base 10, and the opening 112 is located at the tail end of the ramp area 111.
[0021] Working principle: The charging cable 4 is directly installed on the main control board 3. After the smart lock is powered off, there is no need to provide the charging cable 4 separately. Power is supplied to the main control board 3 by using a mobile phone, power bank, or other portable charging device that is paired with the charging cable 4. When the charging cable 4 is located in the assembly cavity, its position is fixed by the cooperation of bolts and limiting posts to prevent it from moving arbitrarily within the assembly cavity. The charging head is partially locked in the positioning area 70, and the opening 112 is covered by a buckle 50 on the cover 5, thus concealing and shielding the charging head. When needed, the buckle 50 is opened, and the charging head is pulled out from the opening 112. It can then be used with a portable power source to supply power to the main control board 3.
