Technical Field

[0001] This utility model relates to the field of cameras, and in particular to a door lock camera protection device. Background Technology

[0002] Cameras are common security monitoring devices used to monitor the state of the environment. They are widely used, including on door locks, to monitor unlocking and provide a good anti-theft effect.

[0003] For example, Chinese patent CN 214659416 U discloses a camera protection device for smart door locks, including a protective cover and a one-way glass plate. By sliding the protective cover upwards, the fingerprint panel and password plate of the fingerprint lock are exposed, and the pinhole camera is covered and protected by the one-way glass plate.

[0004] The aforementioned patent has the following problems:

[0005] This patent has some drawbacks in its use, such as the limitation imposed by the one-way glass plate, which restricts the pinhole camera from protruding too much, thus limiting its monitoring range and preventing 360° monitoring. Therefore, we propose a door lock camera protection device. Utility Model Content

When the trigger switch changes from the pressed state to the unpressed state, a signal is transmitted to the control panel, and then the control panel controls the servo motor to rotate forward.

[0018] In the above technical solution, a spring is further provided between the spring mounting base and the spherical contact, and the outer tube of the telescopic tube passes through the spring. In the natural state of the spring, the front side of the spherical contact protrudes from the front plane of the door lock front shell.

[0019] In this technical solution, when the sliding cover is slid upward, the spherical contact is pressed into the inside of the front shell of the door lock under the pressure of the sliding cover, and the spring is compressed. Then the pressure ring will press the trigger switch.

[0020] In the above technical solution, a trigger switch is further provided on the rear side of the pressure ring, and the trigger switch is fixedly connected to the front shell of the door lock.

[0021] In this technical solution, the trigger switch and the control panel are connected by a wire. The trigger switch is a touch switch that can automatically reset. The pressed state and the non-pressed state will transmit two different signals to the control panel.

A pressure ring 18 is fixedly connected to the rear end of the outer tube of the telescopic tube 16 in this embodiment.

[0035] The transparent protective cover 11 can protect the miniature camera 15. By setting multiple miniature cameras 15, 360-degree monitoring without blind spots can be carried out. In the initial state, the transparent protective cover 11 is located inside the storage hole 2, thereby protecting the transparent protective cover 11 and the miniature camera 15 inside it from damage.

[0036] In this embodiment, a circular slide rail 10 is slidably connected through the middle of the guide rod 12, and the circular slide rail 10 is installed on the front shell 1 of the door lock by means of hexagonal socket bolts. The rear side plane of the hexagonal socket bolts and the circular slide rail 10 cannot protrude from the rear side plane of the front shell 1 of the door lock.

[0037] This design ensures that the rear surface of the front housing 1 of the door lock is flat, making it easy to install the front housing 1 of the door lock onto the door.

[0038] In this embodiment, a password button 4 is provided in the middle of the front side of the front housing 1 of the door lock, and the password button 4 is located below the spherical contact 3. The password button 4 is embedded in the front side of the front housing 1 of the door lock, and the front plane of the password button 4 is flush with the front plane of the front housing 1 of the door lock.

[0039] The password button 4 is used to input the password. By embedding the password button 4 on the front side of the door lock front shell 1, the rear side plane of the sliding cover 5 can be tightly fitted with the front side plane of the door lock front shell 1.

[0040] In this embodiment, a sliding cover 5 is slidably connected to the front side of the door lock front shell 1, and the maximum upward stroke of the sliding cover 5 can cover the storage hole 2. The rear side plane of the sliding cover 5 is in contact with the front side plane of the door lock front shell 1.

[0041] The sliding cover 5 covers the storage hole 2, thereby protecting the camera module 7 inside the storage hole 2 and preventing the camera module 7 from being damaged. The rear side plane of the sliding cover 5 is in contact with the front side plane of the door lock front shell 1 to ensure that when the sliding cover 5 slides upward, the spherical contact 3 will be pressed into the interior of the door lock front shell 1.

[0042] In this embodiment, a control panel 8 is fixedly connected to the upper rear side of the door lock back cover 6, and the trigger switch 19 is connected to the control panel 8 by a wire. The guide rod 12 is hollow inside to allow for wires to be threaded through it. A wire is connected between the miniature camera 15 and the control panel 8, and a wire is connected between the servo motor 14 and the control panel 8.

[0043] When the trigger switch 19 is pressed, it transmits a signal to the control panel 8, and then the control panel 8 controls the servo motor 14 to rotate in reverse. When the trigger switch 19 changes from the pressed state to the unpressed state, it transmits a signal to the control panel 8, and then the control panel 8 controls the servo motor 14 to rotate in forward.

[0044] In this embodiment, a spring 17 is provided between the spring mounting base 9 and the spherical contact 3, and the outer tube of the telescopic tube 16 passes through the spring 17.

[0048] Working principle: The transparent protective cover 11 protects the miniature camera 15. By setting multiple miniature cameras 15, 360-degree monitoring without blind spots can be achieved. Initially, the transparent protective cover 11 is located inside the storage hole 2, thus protecting the transparent protective cover 11 and the miniature camera 15 inside from damage. When the sliding cover 5 is slid down, the sliding cover 5 separates from the spherical contact 3. Then, under the pressure of the spring 17, the pressure ring 18 separates from the trigger switch 19. The trigger switch 19 then transmits a signal to the control panel 8, which controls the servo motor 14 to rotate forward and drive the threaded rod 13 to rotate. Then, under the action of the threaded rod 13, the guide rod 12 slides along the circular slide rail 10 and pushes the transparent protective cover 11 out of the storage hole 2. Then the transparent protective cover 11 is exposed to the outside, so that the miniature camera 15 inside the transparent protective cover 11 can monitor 360 degrees without blind spots. When the sliding cover 5 slides upward and presses against the spherical contact 3, the pressure ring 18 will press the trigger switch 19 and transmit the signal to the control panel 8. Then the control panel 8 will control the servo motor 14 to reverse, so that the transparent protective cover 11 can be put into the storage hole 2, thus protecting the transparent protective cover 11 and the miniature camera 15 inside.
