Description

Technical Field

[0001] This utility model relates to the field of smart door lock technology, and in particular to a smart door lock opening and closing mechanism. Background Technology

[0002] Traditional door locks require keys to unlock, and users often find themselves unable to enter their homes because they forget their keys. To eliminate the hassle of carrying keys, various types of smart door locks have emerged on the market, such as combination locks, proximity locks, and fingerprint locks. However, installing these smart door locks requires removing the existing mechanical door lock and then installing the new smart lock, resulting in waste and significantly increasing the user's operating costs. At the same time, installing these smart door locks requires drilling new holes in the door to fit the smart lock, which reduces door security and increases the difficulty of installation.

[0003] Due to the aforementioned issues, a smart lock device has emerged on the market that can be directly installed onto existing mechanical locks. This type of smart lock controls the rotation of a connecting block, which in turn rotates the lock's unlocking mechanism, thus unlocking or locking the door. However, because the installed lock devices come from various brands of locks, issues such as lock cylinder misalignment and installation deviations sometimes occur. Utility Model Content

[0004] The main objective of this invention is to provide an opening and closing mechanism for a smart door lock, in order to solve the problems existing in the prior art.

[0005] To achieve the above objectives, this utility model provides an opening and closing mechanism for an intelligent door lock, including a transmission mechanism locking block assembly. The locking block assembly includes a connecting block, an adjusting block, and a mounting block. The adjusting block is connected to the connecting block via a first connecting shaft. The upper end of the mounting block is connected to the adjusting block via a second connecting shaft, and the lower end is connected to the transmission mechanism. The first connecting shaft and the second connecting shaft form a staggered cross-shaped structure, and the adjusting block and the mounting block form a universal joint cross-shaped structure.

[0006] Preferably, the transmission mechanism includes a drive gear, a transmission gear, an angle detection gear, a drive shaft, a driven shaft, and a clutch mechanism. The drive gear is meshed with the transmission gear, the angle detection gear is meshed with the transmission gear, the drive gear is connected to the driven shaft, a clutch mechanism is provided between the drive shaft and the driven shaft, and a spring is provided on the drive shaft.

[0007] Preferably, the connecting block has two protrusions symmetrically arranged at both ends, and the two protrusions respectively fit against the two side surfaces of the adjusting block. The first connecting shaft passes through the two protrusions and the connecting hole of the adjusting block, so that the connecting block and the adjusting block are connected.

[0008] Preferably, the mounting block has two protrusions symmetrically arranged at both ends, and the two protrusions respectively fit against the other two sides of the adjusting block. The second connecting shaft passes through the two protrusions and another connecting hole of the adjusting block, so that the mounting block and the adjusting block are connected.

[0009] Preferably, the drive shaft is connected to a motor and a spring is mounted on it, which allows the clutch mechanism in the middle to move left and right.

[0010] The locking and unlocking mechanism of this smart door lock employs a universal joint-like design. This universal joint allows for a variable angle between the input and output shafts. When the angle changes, the universal joint's cross-shaped support rotates accordingly to maintain the bearing's position within the support. This design enables flexible adjustment of the angle between the input and output shafts, adapting to various transmission requirements. Even when the lock is misaligned during assembly, the angle between the input and output shafts changes, ensuring uninterrupted user operation. Attached Figure Description

If the specific posture changes, the directional indicator will also change accordingly.

[0022] Furthermore, the use of terms such as "first" and "second" in this utility model is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. Additionally, the technical solutions of the various embodiments can be combined with each other, but only on the basis of being achievable by those skilled in the art. When the combination of technical solutions is contradictory or impossible to implement, such a combination of technical solutions should be considered non-existent and not within the scope of protection claimed by this utility model.

[0023] In this embodiment of the utility model, reference is made to Figures 1 to 3 A smart door lock opening and closing mechanism includes a transmission mechanism 1 and a locking block assembly 2. The locking block assembly includes a connecting block 201, an adjusting block 202, and a mounting block 203. The adjusting block 202 is connected to the connecting block 201 via a first connecting shaft 204. The upper end of the mounting block 203 is connected to the adjusting block 202 via a second connecting shaft 205, and the lower end is connected to the transmission mechanism 1. The first connecting shaft 204 and the second connecting shaft 205 form a staggered cross-shaped structure, and the adjusting block 202 and the mounting block 203 form a universal joint cross-shaped structure.

[0024] Furthermore, referring to Figure 2 and Figure 3 The connecting block 201 has two protrusions symmetrically arranged at both ends. The two protrusions are respectively attached to the two side surfaces of the adjusting block 202. The first connecting shaft 204 passes through the two protrusions and the connecting hole of the adjusting block 202, so that the connecting block 201 and the adjusting block 202 are connected.

[0025] Furthermore, the mounting block 203 has two protrusions symmetrically arranged at both ends. The two protrusions are respectively attached to the other two sides of the adjusting block 202. The second connecting shaft passes through the two protrusions and another connecting hole of the adjusting block 202, so that the mounting block 203 is connected to the adjusting block 202.

[0026] In this embodiment, the first connecting shaft 204 and the second connecting shaft 205 form a staggered cross-shaped structure, while the adjusting block 202 and the mounting block 203 form a universal joint cross-shaped structure. This is achieved using a mechanism similar to a universal joint, whose design allows the angle between the input and output shafts to vary. When the angle between the two shafts changes, the universal joint's cross-shaped bracket rotates accordingly to maintain the bearing's position within the bracket. This design allows for flexible adjustment of the angle between the input and output shafts, adapting to various transmission requirements. When the lock assembly is eccentric, the angle between the input and output shafts also changes, thus not affecting the user's use of the lock.

[0027] Furthermore, referring to Figure 4 and Figure 5 The transmission mechanism 1 includes a drive gear 101, a transmission gear 102, an angle detection gear 103, a drive shaft 104, a driven shaft 105, and a clutch mechanism 106. The drive gear 101 and the transmission gear 102 are meshed together, as is the angle detection gear 103. The drive gear 101 is connected to the driven shaft 105. A clutch mechanism 106 is provided between the drive shaft 104 and the driven shaft 105. The drive shaft 104 is connected to a motor and has a spring 107 mounted on it. The spring 107 allows the clutch mechanism 106 to move left and right. When the motor rotates normally, the clutch mechanism 106 is forced to move to the right, engaging with the right driven shaft 105, thereby controlling the rotation of the driven shaft 105. When the power is off, the drive shaft 104 stops rotating, and the spring 107 pulls the clutch mechanism 106 back, disengaging it from the driven shaft 105, thus disengaging it from the motor and not affecting the manual opening and closing of the lock.

[0028] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
