[0002] Smart locks are now widespread, with almost every household installing them. Due to increasing aesthetic demands, the market offers a variety of smart lock designs. The complexity of installation varies depending on the type of lock. Generally, smart locks consist of an indoor lock shell, an outdoor lock shell, a lock cylinder assembly, and a sealing plate. These components must be aligned correctly during installation to avoid failure. Existing smart locks typically place the lock cylinder assembly on the indoor lock shell. For those skilled in the art, this requires first placing the indoor lock shell in its corresponding position, then aligning the lock cylinder assembly with the position on the door, and finally placing the outdoor lock shell accordingly. Finally, it's necessary to calibrate the alignment of all three components to ensure they are on the same horizontal line. This complex alignment process makes it difficult for those skilled in the art to correctly position the components, hindering installation and causing problems, especially with smart locks of unusual shapes.

[0018] As shown in the figure, to achieve the above objectives, this utility model provides an easy-to-install smart lock structure, including a first housing 1 for installation indoors, a second housing 2 for installation outdoors, a sealing plate 3, and a lock cylinder assembly 4. The lock cylinder assembly 4 is disposed between the first housing 1 and the second housing 2. The sealing plate 3 is provided with a through hole 31 for the lock cylinder flat rod to pass through, and the second housing 2 is provided with a keyhole 21 for inserting a key. The lock cylinder, the through hole 31, and the keyhole 21 are arranged correspondingly.

[0019] In this implementation, the first housing 1 is fixed to the interior door surface, and the second housing 2 is fixed to the exterior door surface. Both are connected to the pre-drilled mounting holes on the door via bolts. The lock cylinder assembly 4 is positioned between the first housing 1 and the second housing 2, with its ends adapted to the transmission structures inside the two housings. The sealing plate 3 is fixed to the interior side of the door and has a through hole 31 for the lock cylinder flat rod of the lock cylinder assembly 4 to pass through, allowing the flat rod to connect to the unlocking transmission component on the interior side. The exterior side of the second housing 2 has a keyhole 21 for inserting a mechanical key. During installation, it is necessary to ensure that the lock cylinder body of the lock cylinder assembly 4, the through hole 31 of the sealing plate 3, and the keyhole 21 of the second housing 2 are in the correct positions to ensure that the lock cylinder can be smoothly driven after the key is inserted, and that the lock cylinder flat rod can be normally transmitted through the through hole 31, realizing the mechanical unlocking function of the lock and making installation more convenient.

[0020] As one specific implementation of the improvement, the lock cylinder, through hole 31, and keyhole 21 are arranged coaxially.

[0021] In this design, the main axis of the lock cylinder, the central axis of the through hole 31 of the sealing plate 3, and the central axis of the keyhole 21 of the second housing 2 are collinear. During installation, the positioning pins on the first housing 1 and the second housing 2 can be engaged with the positioning holes on the door body to ensure the relative positions of the two housings are fixed, thereby ensuring the coaxiality of the keyhole 21 and the lock cylinder. When installing the sealing plate 3, the axis of the lock cylinder flat rod is used as a reference to align the center of the through hole 31 with the axis of the flat rod, ultimately achieving coaxiality of the three components. This coaxial arrangement reduces radial resistance when the key is inserted, avoids friction and jamming between the key and the inner wall of the keyhole 21, ensures that the lock cylinder flat rod does not deviate when it moves within the through hole 31, reduces wear between the flat rod and the inner wall of the through hole 31, improves the smoothness of the lock's mechanical operation and service life, reduces the complexity of installation, facilitates installation and calibration, and makes operation more convenient.

[0022] As an improved embodiment, the lock cylinder assembly 4 is detachably connected to the sealing plate 3, and the sealing plate 3 is provided with at least one lock cylinder seat 32 for fixing the lock cylinder assembly 4. The lock cylinder assembly 4 and the lock cylinder seat 32 are fixed by bolts.

[0023] In the implementation of this solution, the first method is as follows: the lock cylinder seat 32 is a raised structure with screw holes, and the lock cylinder assembly 4 has a through mounting hole at the corresponding position. During installation, the lock cylinder assembly 4 is attached to the surface of the lock cylinder seat 32 so that the mounting hole is aligned with the screw hole of the lock cylinder seat 32. The lock cylinder assembly 4 is fixed to the sealing plate 3 by passing a bolt through the mounting hole and screwing it into the screw hole.

[0024] The second implementation method is as follows: the lock cylinder seat 32 is provided with an outwardly extending stud, and the lock cylinder assembly 4 is provided with a through hole 31 that matches the stud at the corresponding position. During installation, the through hole 31 of the lock cylinder assembly 4 is fitted onto the stud, and then tightened and fixed by a nut.

[0025] The preferred embodiment of this solution is the first implementation method. After the lock cylinder assembly 4 is placed on the sealing plate 3, the sealing plate 3 only needs to be fixed on the door. After that, the first housing 1 and the second housing 2 are respectively arranged coaxially with the lock cylinder assembly 4, making the installation quicker and more convenient.

[0026] As an improved specific embodiment, the lock cylinder seat 32 includes an annular sidewall 321, with the other end inclined toward the sealing plate 3. The radial width of the annular sidewall 321 toward the sealing plate 3 is greater than the radial width of the annular sidewall 321 and the annular arc-shaped top wall 322.

[0027] In this design, the lock cylinder seat 32 includes an annular sidewall 321. One end of the annular sidewall 321 is fixedly connected to the sealing plate 3, and the other end extends away from the sealing plate 3, with its end inclined towards the sealing plate 3. The radial width of the annular sidewall 321 gradually increases from the side away from the sealing plate 3 to the side closer to the sealing plate 3, that is, the radial width of the annular sidewall 321 towards the sealing plate 3 is greater than its radial width away from the sealing plate 3. In this design, the annular sidewall 321 has a continuous conical structure when not connected to other structures. This structural design provides a larger support area at the connection between the lock cylinder seat 32 and the sealing plate 3, improving the structural strength of the connection between the lock cylinder seat 32 and the sealing plate 3. The inclined end can guide the installation of the lock cylinder assembly 4, facilitating quick alignment and installation. At the same time, the inclined surface fits against the surface of the lock cylinder assembly 4, increasing the contact area between the two, improving the stability after fixing, and reducing the shaking of the lock cylinder assembly 4 during use.

[0028] As an improved specific embodiment, the lock cylinder seat 32 includes an annular arc-shaped top wall 322, one end of which is circumferentially connected to the annular side wall 321, and the other end is able to abut against the lock cylinder assembly 4. The lock cylinder assembly 4 has an annular notch 421 at the position corresponding to the annular arc-shaped top wall 322, and the annular arc-shaped top wall 322 is partially embedded in the annular notch 421.

[0029] In this design, one end of the annular arc-shaped top wall 322 is connected to the circumferential edge of the annular side wall 321, while the other end extends towards the lock cylinder assembly 4, abutting against the outer peripheral wall of the lock cylinder assembly 4. An annular notch 421 is provided on the outer peripheral wall of the lock cylinder assembly 4 at a position corresponding to the annular arc-shaped top wall 322, the curvature of which matches the curvature of the annular arc-shaped top wall 322. During installation, after the lock cylinder assembly 4 and the lock cylinder seat 32 are fixed with bolts, the free end of the annular arc-shaped top wall 322 is partially embedded in the annular notch 421, forming an axial limit. This structure, through the interlocking of the annular arc-shaped top wall 322 and the annular notch 421, further restricts the axial displacement of the lock cylinder assembly 4, preventing it from shifting along the axial direction under stress. Simultaneously, in conjunction with the radial positioning of the annular side wall 321, the installation and positioning of the lock cylinder assembly 4 are more precise, improving the overall stability of the lock structure.

[0030] As an improved specific embodiment, the lock cylinder assembly 4 includes a motor 41 for driving the electric lock cylinder. The motor 41 has a cylindrical housing 411. The sealing plate 3 is provided with a latch window 33 for engaging the motor 41. The housing 411 can be partially engaged in the latch window 33 and abut against the inner peripheral wall of the latch window 33.

[0031] In this design, a locking window 33 is provided on the sealing plate 3 corresponding to the position of the motor 41. The shape of the locking window 33 is adapted to the outer circumference of the motor housing 411, and is either circular or arc-shaped to match the curvature of the housing 411. During installation, the cylindrical housing 411 of the motor 41 is partially inserted into the locking window 33, so that the outer circumferential wall of the housing 411 abuts against the inner circumferential wall of the locking window 33, achieving initial positioning of the motor 41. Then, the lock cylinder assembly 4 is fixed to the lock cylinder seat 32 as a whole by bolts. The locking window 33 can provide radial restraint for the motor 41, reducing the displacement of the motor 41 caused by vibration during operation, while also sharing the radial force on the bolts, preventing the bolts from loosening due to long-term stress, and improving the stability of the motor 41 installation.

[0032] As an improved specific implementation, the lock cylinder assembly 4 includes a lock cylinder body 42, and a screw hole is provided on the lock cylinder body 42 for screws to fix it on the lock cylinder seat 32 at each position corresponding to the lock cylinder seat 32. The annular notch 421 is provided corresponding to the screw hole.

[0033] In implementation, the lock cylinder assembly 4 includes a lock cylinder body 42. Each lock cylinder seat 32 has a corresponding screw hole on its body, with the axis of the screw hole parallel to the radial direction of the lock cylinder body 42. An annular notch 421 is located on the lock cylinder body 42 corresponding to the lock cylinder seat 32, and its position corresponds to the screw hole, meaning the screw hole is within the notch range of the annular notch 421. During installation, the bolt passes through the mounting hole of the lock cylinder seat 32 and is screwed into the screw hole of the lock cylinder body 42. At this time, the annular arc-shaped top wall 322 is partially embedded in the annular notch 421. The annular notch 421 provides operating space for bolt installation, preventing the annular arc-shaped top wall 322 from obstructing the screw hole. Simultaneously, it complements the bolt tightening direction and the limiting direction of the annular arc-shaped top wall 322, ensuring the fixing strength between the lock cylinder body 42 and the lock cylinder seat 32 without affecting the fitting of the annular arc-shaped top wall 322 and the annular notch 421, thus improving the rationality of the structural design.

[0034] As an improved embodiment, the sealing plate 3 is provided with a handle 34 and a handle seat 35 for fixing the handle 34, and the handle 34 and the handle seat 35 are fixed by bolts.

[0035] In this design, the handle base 35 is a boss structure fixed to the surface of the sealing plate 3. It contains an internal transmission component that connects to the handle 34, and an external connecting part for mounting the handle 34. The end of the handle 34 has a mounting hole that matches the connecting part of the handle base 35. During installation, the end of the handle 34 is placed against the connecting part of the handle base 35, aligning the mounting holes. Bolts are then passed through the mounting holes and tightened to secure the handle 34 to the handle base 35. The handle base 35 ensures a more stable connection between the handle 34 and the sealing plate 3, preventing excessive localized stress and deformation of the sealing plate 3 caused by directly mounting the handle 34 onto it. Simultaneously, the handle base 35 is positioned to avoid the through hole 31 on the sealing plate 3 and the mounting area of ​​the lock cylinder assembly 4, ensuring that the transmission of the handle 34 during operation does not interfere with the transmission of the lock cylinder flat rod, thus guaranteeing the normal function of the lock.

[0036] The above are merely preferred embodiments of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are within its protection scope. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within its protection scope.
