Description

Technical Field

[0001] This application relates to the field of lock technology, specifically to the field of smart lock technology. Background Technology

[0002] As people increasingly value convenience and security, smart locks are becoming more widespread. However, smart locks are generally expensive, and if they are not properly fitted to the door thickness after purchase, they are difficult to replace. Furthermore, improper adjustment of the back thickness can compromise security.

[0003] The conventional approach is to add a steel beam and adjust the back thickness by adjusting the width of the steel beam. However, adding new parts in this way will affect the processing efficiency and increase the cost, while also easily causing errors and affecting the fundamental security of the lock.

[0004] Users want smart locks that are not only reasonably priced, but also easily adaptable to different door thicknesses, ensuring convenient installation and adjustment. Summary of the Invention

[0005] To address the aforementioned issues, this application proposes a smart lock designed to improve upon at least one of the problems described above, providing an easily adjustable and highly secure smart combination lock.

[0006] To achieve the above objectives, the present application adopts the following technical solution:

[0007] A smart lock includes a lock cylinder, an indoor knob, and an outdoor smart handle. The indoor knob is equipped with a back thickness adjustment mechanism, and the outdoor smart handle is equipped with a smart unlocking part.

[0008] The lock cylinder includes an actuating component that rotates under the drive of the indoor knob and the outdoor smart handle. The actuating component has a lock housing and a support beam at both ends and the lower end. The lock housing and the support beam are an integral structure.

[0009] The outdoor smart handle is provided with a bushing that connects to the lock housing, and the support beam is provided with a boss that supports the bushing in the direction of the outdoor smart handle.

[0010] Thus, by incorporating a back thickness adjustment mechanism at the indoor knob, the back thickness can be adjusted in the indoor direction, ensuring the safety and stability of the outdoor smart handle. Simultaneously, the integrated design of the lock housing and support beam guarantees overall stability, and the resulting rigidity issues are further addressed through the design of bushings and bosses to enhance safety.

[0011] In some preferred embodiments, the lock housing and the support beam are designed as a single piece of copper.

[0012] In some possible implementations, the smart unlocking unit is located at the upper end of the outdoor smart handle.

[0013] In some possible implementations, the smart unlocking unit is a fingerprint lock or a password button.

[0014] In some possible implementations, the back thickness adjustment mechanism includes an interior locking shaft with multiple pin holes, a positioning hole on the interior knob corresponding to at least one of the multiple pin holes, and an adjustment pin positioned in the pin hole through the positioning hole.

[0015] In this way, the back thickness can be adjusted by adjusting the distance of the indoor knob to make the positioning hole and the pin hole correspond, and the adjusting pin can be inserted for positioning, without affecting the stability of the outdoor smart handle.

[0016] In some possible implementations, the outdoor smart handle has a power supply module, a spare lock hole, and an external charging port on the outdoor-facing end, with the external charging port located at the top.

[0017] In some possible implementations, the power supply module uses dry cell batteries and has a flip cover that can be rotated open.

[0018] In some possible implementations, the lock housing is provided with multiple guide grooves.

[0019] In a preferred embodiment, there are two guide grooves, which are respectively disposed at both ends of the puller. Attached Figure Description

[0025] The following examples further illustrate the features of this application and other related features in detail, so as to facilitate understanding by those skilled in the art:

[0026] It should be noted that the terms “front,” “back,” “left,” “right,” “up,” and “down” used in the following description refer to the directions in the attached diagrams, while the terms “bottom surface,” “top surface,” “inner,” and “outer” refer to the directions toward or away from the geometric center of a specific component, respectively.

[0027] Please refer to Figure 1 The arrows in the diagram indicate indoor and outdoor orientations based on actual installation conditions. When installing a smart lock, it's crucial to ensure the lock cylinder 1 in the center matches the door thickness and that the outdoor smart handle 3 provides secure stability; in other words, the outdoor smart handle 3 must fit snugly against the door.

[0028] This application discloses a smart lock, including a lock cylinder 1, an indoor knob 2, and an outdoor smart handle 3. The indoor knob 2 only needs to be easy to rotate and may be provided with anti-slip texture. The outdoor smart handle 3 is equipped with a smart unlocking part 31 for unlocking. The smart unlocking part 31 is preferably located at the upper end of the outdoor smart handle 3 for easy operation. The lock can be either a fingerprint lock or a keypad; for an example of a keypad implementation, please refer to [reference needed]. Figure 5 .

[0029] As mentioned above, the smart lock requires unlocking via the smart unlocking unit 31, and then it unlocks electrically, which requires a power source. Please refer to [link / reference needed]. Figure 2 The image shows the state after the outer cover at the end is removed. The outer cover can be fixed by means of clips, screws, etc., and there are no restrictions on this.

[0030] The outdoor smart handle 3 has a power supply module 33, a spare lock hole 34, and an external charging port 35 on its outdoor-facing end. The external charging port 35 is located at the top, so that the circuit board (not shown in the figure) can be placed at the top for easy connection to both the smart unlocking unit 31 and the external charging port 35.

[0031] Preferably, the power supply module 33 uses dry cell batteries, such as four AAA batteries. To facilitate the replacement of dry cell batteries, a flip cover 331 with a rotatable opening is provided at the end.

[0032] Furthermore, the indoor knob 2 is equipped with a back thickness adjustment mechanism. As one embodiment of the back thickness adjustment mechanism, please refer to [reference needed]. Figure 3 The back thickness adjustment mechanism includes an indoor locking shaft 22 with multiple pin holes 21, a positioning hole 23 on the indoor knob 2 corresponding to at least one of the multiple pin holes 21, and an adjustment pin 24 that passes through the positioning hole 23 and is positioned in the pin hole 21.

[0033] Thus, the back thickness can be adjusted by adjusting the distance of the indoor knob 2 so that the positioning hole 23 and the pin hole 21 correspond, and by inserting the adjusting pin 24 for positioning. Adjusting the back thickness in the indoor direction can ensure the safety and stability of the outdoor smart handle 3.

[0034] Further, please refer to Figure 1 The lock cylinder 1 includes an actuating member 11 that rotates under the drive of the indoor knob 2 and the outdoor smart handle 3. The actuating member 11 has a lock housing 12 and a support beam 13 at both ends and the lower end. As described above, the back thickness adjustment mechanism has been solved at the indoor knob 2; therefore, the lock housing 12 and support beam 13 of this application are designed as an integrated structure, preferably an integrated design using copper material with good ductility.

[0035] However, using a single-piece design, especially with highly malleable materials, can lead to insufficient rigidity. Please refer to the following for details. Figure 4 The smart lock of this application has a bushing 32 that connects to the lock housing 12 on the outdoor smart handle 3, and the support beam 13 has a boss 14 that supports the bushing 32 in the direction of the outdoor smart handle 3.

[0036] In this way, the lock housing 12 and the support beam 13 are designed as an integrated unit, which can ensure the overall stability. As for the stiffness problem caused by this, the design of the bushing 32 and the boss 14 further improves the safety.

[0037] Please refer to Figure 1 In some embodiments of this application, to further improve security and stability, the lock housing 12 is provided with a plurality of guide grooves 121. Preferably, there are two guide grooves 121, which are respectively disposed at both ends of the actuating member 11.

[0038] As stated above, this application protects a smart lock, and all technical solutions that are the same as or similar to this application should be considered to fall within the scope of protection of this application.
