Description

Technical Field

[0001] The present invention relates to the technical field of door lock facilities, and particularly to an emergency power supply structure for a lock and a smart lock.

Background Art

[0002] With the popularization of smart locks, many users are replacing traditional mechanical locks with smart locks. Such smart locks operate an internal clutch module by inputting unlocking information such as a correct password or fingerprint to achieve unlocking. Conventional smart locks require power supply, and generally, a battery is installed inside the lock for power supply. When the power of the battery is insufficient, the smart lock enters a low-power or power-off state, and the user cannot unlock the lock from outside the door. In such a case, emergency power supply is performed by an external power source, and the smart lock recognizes the unlocking information and operates the clutch module to achieve unlocking. In the prior art, generally, a charging port is fixedly provided on the door lock, and the user connects the charging port and a portable power source with a cable from outside the door. The power of the portable power source is supplied to the smart lock via the cable and the charging port to provide emergency power supply. Thereby, the user can achieve unlocking outside the door.

[0003] However, it is common for many users not to carry a portable power source or a charging cable when going out. When emergency unlocking is required, since there is no portable power source or charging case, unlocking by emergency power supply is impossible, and such inconvenience exists for unlocking a smart lock by emergency power supply.

[0023] The present invention discloses a smart lock, including an emergency power supply structure for the lock, etc. Here, referring to FIGS. 1 to 4, the emergency power supply structure for the lock includes a case 10, a blocking part 20, an end cover 30, a wire structure, and a wire engagement assembly 50. An attachment chamber 11 is provided at the front end of the case 10. The blocking part 20 is provided in the attachment chamber 11, and a first attachment groove 21 is provided on the front side of the blocking part 20. The end cover 30 is located at the front end of the attachment chamber 11. The end cover 30 is movably attached to the blocking part 20, and the end cover 30 shields the first attachment groove 21. The wire structure is provided separately from the end cover 30 (that is, the wire structure is not connected to the end cover 30). The wire structure includes a plug 41 and a power line 42. The plug 41 is engaged in the first attachment groove 21. One end of the power line 42 is connected to the plug 41, and the other end extends into the case 10 and is connected.

[0024] When it is necessary to supply emergency power to the smart lock, move the end cover 30. Expose the plug 41 in the attachment groove, move the plug 41 to release the engagement between the plug 41 and the first attachment groove 21, and detach the plug 41 from the first attachment groove 21. If it is a mobile phone with an OTG external discharge function, the mobile phone held by the user can be connected to the plug 41, and the smart lock is supplied with emergency power by external discharge from the mobile phone to meet the power consumption demand for unlocking the door lock. Compared with the case where it is necessary to carry both a portable power source and a charging cable for emergency power supply, in this solution, if the user has a mobile phone, emergency power supply and unlocking can be performed, making it easier for the user to supply emergency power to the smart lock and unlock it.

[0025] In addition, many conventional portable power sources also have a reverse discharge function at the charging port, and many portable power sources have a discharge port that fits the plug 41.

[0027] According to this structure, the end cover 30 and the closing part 20 can be connected, the end cover 30 can be moved to detach the second mounting column 33 from the first through hole 221, and because the length of the first mounting column 31 is greater than the thickness of the first sheet 22, the end cover 30 can be moved forward to detach from the mounting chamber 11 and rotated, making it easier for the user to remove the plug 41 and to swing the power line 42 connected to the plug 41 sufficiently, thereby making it easier to connect the plug 41 to a mobile phone.

[0028] In this embodiment, a first engagement groove 24 is further provided at the other end of the closing portion 20. Specifically, the first engagement groove 24 is provided on both opposing side walls of the first mounting groove 21, and two engagement hooks 35 are provided opposite each other at the other end of the end cover 30. The engagement hooks 35 are hooked into the first engagement groove 24. This structure improves the stability of the connection between the end cover 30 and the closing portion 20.

[0029] In this embodiment, engaging projections 211 are further provided on both opposing side walls of the first mounting groove 21, and the plug 41 is mounted between the two engaging projections 211. Specifically, the distance between the two engaging projections 211 is approximately equal to the width of the plug 41, and when mounting, the plug 41 is moved to reach the rear side via the two engaging projections 211, thereby engaging the plug 41 within the first mounting groove 21.

[0030] In this embodiment, the wire engagement assembly 50 includes a first engagement portion 51, a second engagement portion 52, a first screw 53, and a second screw 54, wherein the first engagement portion 51 and the second engagement portion 52 are provided opposite each other, the power line 42 is positioned by being sandwiched between the first engagement portion 51 and the second engagement portion 52, the first screw 53 is drilled into the first engagement portion 51 and screwed into the second engagement portion 52, and the second screw 54 is drilled into the second engagement portion 52 and screwed into the case.

[0031] In this embodiment, a second mounting groove 25 is provided in the closure portion 20, one end of the second mounting groove 25 is in communication with the first mounting groove 21, the power line 42 is located within the second mounting groove 25, and a third mounting groove 26 is provided in communication with the other end of the second mounting groove 25, the vertical width of the third mounting groove 26 is greater than the vertical width of the second mounting groove 25. This structure allows the power line 42 and the plug 41 to have a larger swing range, making it easier for the user to operate the plug 41 and connect it to the mobile phone.

[0032] Referring to Figure 5, in some embodiments, an L-shaped first stop bar 12 is provided inside the case 10, the first stop bar 12 is located on the rear side of the closing portion 20, and a mounting passage 13 extending in the rear direction is formed between one side of the first stop bar 12 and the inner wall of the case 10.
