Detailed Implementation
[0018] The above-described solution will be further illustrated below with reference to specific embodiments. It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of this application. The implementation conditions used in the embodiments may be further adjusted according to the conditions of specific manufacturers, and the implementation conditions not specified are generally those in routine experiments.
[0019] A smart lock with a battery compartment protection structure, such as Figures 1-5 As shown, the lock includes a smart lock body 1, a battery compartment 2, a protective cover 3, locking blocks 5, push blocks 6, a spring 7, a control panel 16, an anti-slip mat 8, a sealing ring 9, a placement frame 11, a water-absorbing resin mat 10, a connecting block 12, a camera 13, a small motor 14, and a protective rubber sheet 15. The smart lock body 1 is connected to the battery compartment 2 and the control panel 16. The control panel 16 is electrically connected to the smart lock body 1. The protective cover 3 is snapped onto the battery compartment 2. At least two locking blocks 5 are slidably connected to the side of the protective cover 3 near the battery compartment 2. A spring 7 connects the locking blocks 5 to the protective cover 3. The smart lock body 1 has slots 4 on both sides near the battery compartment 2 that are adapted to the locking blocks 5. The sides of the locking blocks 5 that are far apart from each other are sloped. The area of the side of the locking block 5 near the battery compartment 2 is smaller than the area of the side that is far away from the battery compartment 2. On one side of the area, at least two push blocks 6 are slidably connected to the side of the protective cover 3 away from the battery compartment 2. The push blocks 6 are fixedly connected to the locking block 5. Anti-slip pads 8 are connected to the sides of the push blocks 6 that are far from each other. A sealing ring 9 is connected to the side of the battery compartment 2 near the protective cover 3. A placement frame 11 is connected to the side of the protective cover 3 near the battery compartment 2. A water-absorbing resin pad 10 is slidably connected inside the placement frame 11. A connecting block 12 is connected inside the smart lock body 1. A camera 13 is rotatably connected to the connecting block 12. The camera 13 passes through the side of the smart lock body 1 away from the battery compartment 2. A small motor 14 is installed on the connecting block 12. The output shaft of the small motor 14 is fixedly connected to the camera 13. A protective rubber sheet 15 is connected to the side of the smart lock body 1 away from the battery compartment 2. The protective rubber sheet 15 is fixedly connected to the camera 13.
[0020] Initially, the locking block 5 is engaged in the slot 4, and the spring 7 is in its natural state. When the battery needs to be replaced, press the two buttons 6 with your fingers, causing them to slide closer together. This allows the locking block 5 to slide out of the slot 4, compressing the spring 7. Then, use the two buttons 6 to remove the protective cover 3 from the battery compartment 2. Release the buttons 6, and the spring 7 returns to its original state, causing the locking blocks 5 to slide away from each other. Install the battery in the battery compartment 2, align the protective cover 3 with the battery compartment 2, and press the protective cover 3. This causes the inclined surface of the locking block 5 to press against the inner wall of the battery compartment 2, causing the two locking blocks 5 to slide closer together and compress the spring 7. When the locking block 5 approaches the slot 4, the spring 7 returns to its original state. Under the elastic force of the spring 7, the locking block 5 slides into the slot 4, thus completing the battery installation. When someone is outside the door, the camera 13 can capture the situation outside the door. The small motor 14 can drive the camera 13 to rotate, so that the camera 13 can capture the blind spots outside the door, improving the security of this smart lock. The protective rubber sheet 15 can ensure that the camera 13 can rotate freely, while also preventing humid air from entering between the camera 13 and the smart lock body 1, further improving the moisture-proof effect of this smart lock.
