Fixed plates 5 are fixedly installed on both sides of the smart door lock body 1, and T-shaped grooves 6 are opened on the front of the two fixed plates 5. The fronts of the two fixed plates 5 on one side of the T-shaped groove 6 are respectively fixedly connected to the backs of both sides of the fixed cover 7, and the bottom end of the fixed cover 7 is coplanar with the top end of the smart door lock body 1, and the distance from the bottom end of the inner cavity of the fixed cover 7 to the bottom end of the electromagnet 11 is equal to the distance from the bottom end of the fixed cover 7 to the top end of the end plate 12, so as to ensure that the protective cover 8 can just The intelligent control area 4 is completely closed and protected. The interiors of the two T-shaped slide grooves 6 are respectively slidably connected to the back sides of the two sides of the protective cover 8. The top of the protective cover 8 extending into the fixed cover 7 is fixedly connected with an iron sheet 9. The two sides of the iron sheet 9 are slidably connected to the inner wall of the fixed cover 7. The middle part of the top of the iron sheet 9 is fixedly connected with a reset spring 10. The initial length of the reset spring 10 is twice the length of the inner cavity of the fixed cover 7, and the reset spring 10 is a SPEC polymer plastic spring, which ensures that the reset spring 10 is always in a compressed rebound state with respect to the protective cover 8. The polymer plastic spring can effectively prevent the reset spring 10 from being electromagnetically interfered with by the electromagnets 11 on both sides. The other end of the reset spring 10 is fixedly connected to the top of the inner cavity of the fixed cover 7. The top of the inner cavity of the fixed cover 7 and located at the reset spring 1 0 is fixedly installed with electromagnets 11 on both sides, the reset spring 10 and the two electromagnets 11 are in the same horizontal plane, and the two electromagnets 11 are symmetrically distributed on the left and right sides of the reset spring 10, ensuring that the electromagnets 11 have balanced adsorption forces on both sides of the iron sheet 9 when energized, thereby ensuring the synchronization of sliding on both sides of the iron sheet 9, the bottom ends of the front sides of the two fixed plates 5 are respectively fixedly connected to the back sides of both sides of the end plate 12, and a proximity sensor 13 is fixedly installed in the middle of the front side of the end plate 12, the signal output end of the proximity sensor 13 is electrically connected to the input end of the signal processor 17, the output end of the signal processor 17 is electrically connected to the input end of the electromagnet 11 and the input end of the buzzer 3, the proximity sensor 13 sends a proximity signal to the signal processor 17, and the signal After the processor 17 processes, the control electromagnet 11 is energized, and the proximity sensor 13 sends the away signal to the signal processor 17. After the signal processor 17 processes, the control electromagnet 11 is de-energized, and the control buzzer 3 is controlled to emit a short alarm sound. The fixed cover 7 is located on one side of the T-shaped slide 6 and is fixedly connected with an anti-collision spring 14. The other end of the anti-collision spring 14 is fixedly connected with a baffle 15. The end of the T-shaped slide 6 on the other side of the baffle 15 is fixedly installed with a block 16. The length of one side of the block 16 exceeding the side of the end plate 12 is the same as the length of one side of the baffle 15 recessed into the side of the fixed cover 7. A sponge cushion layer is provided on the side of the block 16 close to the baffle 15, and the cushion layer thickness is 2 cm, which effectively prevents the protective cover 8 from rebounding under the action of the reset spring 10.The end plate 12 makes a collision sound, thereby improving the experience of using the device.

At the same time, by setting an anti-collision spring 14, a baffle 15 and a block 16, it can effectively prevent the protective cover 8 from generating a large impact sound when it rebounds and closes under the action of the reset spring 10, thereby improving the user experience of the device; by setting a proximity sensor 13, it detects the user's hand approaching and moving away from the smart door lock body 1, so as to control the electromagnet 11 to the iron The adsorption force of the sheet 9 can realize the automatic control of the opening and closing of the protective cover 8, further improving the automation degree of the smart door lock. When the user is away from the smart door lock body 1, the proximity sensor 13 controls the electromagnet 11 to cut off the power, and the reset spring 10 bounces the protective cover 8 back to its original position and closes it. At the same time, the proximity sensor 13 is controlled to send a short alarm to remind the user to observe whether the protective cover 8 is closed in place, which is convenient to use. It solves the problem that the intelligent recognition area of ​​the smart door lock is mostly exposed to the outside, which is easy to cause scratches and damage during normal use, and the cost of repair or replacement is high, which indirectly increases the cost of use. Smart door locks with protective covers are mostly manually pushed and pulled, and the user often forgets to close the protective cover after opening the door.
