Description

Technical Field

[0001] The utility model belongs to the technical field of smart door locks, and in particular relates to a protective device for a smart door lock. Background Art

[0002] Smart door locks are different from traditional mechanical locks. They are more intelligent and simple in terms of user security, identification, and management. They are the executive components of door locking in the access control system. Through advanced technical means such as biometric recognition and remote control, they realize intelligent management of door locks.

[0003] When using a touch-type smart door lock, the user controls the door lock through touch operations and can enter a preset password on the touchpad to unlock the door. When the smart door lock is directly hit by external force, the touchpad, as an exposed part, is likely to bear the brunt of the impact. The strong impact force may cause damage to the electronic components inside the touchpad, thereby affecting its normal function. The problem with the above technology is that the touchpad protection device of the existing smart door lock uses a sliding baffle to block the front side of the touchpad to prevent the touchpad from being hit. After moving upward, the baffle may tilt due to itself, causing the baffle to be unable to fall naturally. Utility Model Content

[0004] In view of the problems existing in the prior art, the present invention provides a protective device for an intelligent door lock that can overcome the above problems or at least partially solve the above problems.

[0005] The utility model is implemented as follows: a protective device of a smart door lock comprises a smart door lock and a mounting assembly, wherein the smart door lock comprises a lock body, a handle and a touch panel, the rear side of the touch panel is fixedly connected to the front side of the lock body, the handle is mounted on the front side of the lock body, the mounting assembly comprises a mounting plate, a bottom plate, two movable tooth plates, two fixed tooth plates and two filling pads, the interior of the mounting plate is movably connected to the surface of the lock body, the top of the bottom plate is movably connected to the bottom of the lock body, the surfaces of the two movable tooth plates are respectively fixedly connected to the left and right sides of the interior of the mounting plate, the bottoms of the two fixed tooth plates are fixedly connected to the left and right sides of the top of the bottom plate, the surfaces of the two fixed tooth plates are both movably connected to the surfaces of the two movable tooth plates, the opposite sides of the two filling pads are respectively fixedly connected to the opposite ends of the two fixed tooth plates, and a protective assembly is provided on the front side of the mounting plate;

[0006] The smart door lock is used to lock the door;

[0007] The installation component is used to install and fix the protection component;

[0008] The protective component is used to prevent the touch panel from being damaged by collision.

[0009] In order to prevent the touch panel from being hit, preferably, the protective assembly includes a rotating shaft, a connecting sleeve, a protective plate and a pull rod. The left side of the rotating shaft is fixedly connected to the left side of the inside of the mounting plate, the right side of the rotating shaft is fixedly connected to the right side of the inside of the mounting plate, the inside of the connecting sleeve is movably connected to the surface of the rotating shaft, the protective plate is located on the front side of the touch panel, the top of the rear side of the protective plate is fixedly connected to the front side of the connecting sleeve, the rear side of the pull rod is fixedly connected to the front side of the protective plate, and the front side of the touch panel is blocked by the protective plate to prevent the touch panel from being hit.

Fixed tension springs are provided inside the two limit blocks, and the opposite sides of the two fixed tension springs are respectively fixedly connected to the opposite ends of the two movable tooth plates, and the side of the mounting plate close to the two fixed tension springs is respectively fixedly connected to the opposite ends of the two fixed tension springs, and the two fixed tension springs generate a pulling force toward the opposite ends of the two movable tooth plates through the two fixed tension springs, thereby limiting the movement of the two movable tooth plates, thereby keeping the two movable tooth plates in close contact with the two fixed tooth plates.

[0011] In order to enable the protective plate to reset after moving upward, preferably, the left and right sides of the interior of the rotating shaft are fixedly connected with reset torsion springs, and the opposite ends of the two reset torsion springs are fixedly connected with connecting blocks, and the surfaces of the two connecting blocks are movably connected to the interior of the rotating shaft, and the sides of the two connecting blocks close to the connecting sleeve are fixedly connected to the interior of the connecting sleeve. During the movement of the protective plate, the connecting sleeve is driven to rotate around the rotating shaft, and the rotation of the connecting sleeve drives the two connecting blocks to rotate. During the rotation of the two connecting blocks, the two reset torsion springs are deformed. After the anti-slip plate is released, the two reset torsion springs rebound, thereby driving the connecting sleeve to reset through the two connecting blocks, thereby moving the protective plate to the front side of the touch panel.

The rear sides of the two side panels are movably connected to the front sides of the two buffer pads. The two side panels are driven to move during the resetting process of the protective plate, and the rear sides of the two side panels contact the two buffer pads.

The two fixing springs 5 ​​generate a pulling force toward the opposite ends of the two movable tooth plates 203 to limit the movement of the two movable tooth plates 203, so that the two movable tooth plates 203 maintain close contact with the two fixed tooth plates 204. In order to enable the protective plate 303 to reset after moving upward, the left and right sides of the rotating shaft 301 are fixedly connected to the return torsion springs 6.

[0025] The working principle of this utility model:

[0026] When installing the protective component 3, the mounting plate 201 is placed on the top of the surface of the lock body 101, the two fixed tooth plates 204 are aligned with the left and right sides of the bottom of the mounting plate 201, and the bottom plate 202 is moved upward. During the movement of the bottom plate 202, the two fixed tooth plates 204 are driven to move into the interior of the mounting plate 201. The two fixed tooth plates 204 squeeze the two movable tooth plates 203, driving the two movable tooth plates 203 to move to the opposite side. During the movement of the two movable tooth plates 203, the two fixed tension springs 5 ​​are deformed. After the bottom of the bottom plate 202 contacts the lock body 101, the two fixed tension springs 5 ​​rebound, driving the two movable tooth plates 203 to move to the opposite end. The two movable tooth plates 203 limit the movement of the two fixed tooth plates 204, so that the bottom plate 202 remains stable. When the lock needs to be unlocked, the pull rod 304 drives the protective plate 303 to move upward. During the movement of the protective plate 303, the connecting sleeve 302 is driven to rotate around the rotating shaft 301. During the rotation of the connecting sleeve 302, the two connecting blocks 7 are driven to rotate. During the rotation of the two connecting blocks 7, the two reset torsion springs 6 are deformed. When the pull rod 304 is released after unlocking, the two reset torsion springs 6 rebound, thereby driving the connecting sleeve 302 to reset through the two connecting blocks 7, so that the protective plate 303 moves to the front side of the touch panel 103 and remains stable.
