[0037] like Figures 1 to 9 As shown, a multifunctional intelligent door lock includes a door lock front panel 1, as shown Figure 4 As shown, a smart screen 101, a password fingerprint touch screen 102 and a camera assembly 103 are arranged on one side of the door lock front panel 1, a handle groove 104 is opened on one side of the door lock front panel 1, a storage box 2 is fixedly installed on the top and bottom of the door lock front panel 1, a magnetic door 3 is rotatably installed on one side of the storage box 2 clamping the handle groove 104, a transmission box 4 is fixedly installed on the side of the storage box 2 away from the handle groove 104, and the transmission box 4 is connected to the inside of the storage box 2, as shown in FIG. Figure 5 As shown, a transmission motor 5 is fixedly installed inside the transmission box 4. Figure 6 As shown, the output end of the transmission motor 5 is driven to install a transmission shaft 6, one end of the transmission shaft 6 extends to the inside of the storage box 2 and is fixedly sleeved with an assembly cylinder 7, and a winding cylinder 8 is movably sleeved on the assembly cylinder 7, as shown in FIG. Figure 7 , Figure 8 As shown, a plurality of evenly distributed transmission bars are arranged on the circumference of the assembly cylinder 7, a plurality of transmission grooves 801 adapted to the transmission bars are opened on the inner wall of the winding cylinder 8, and a transparent protective film 9 is rolled up on the winding cylinder 8 at the top, as shown in FIG. Figure 4 As shown, a guide groove plate 10 is fixedly installed on one side of the storage box 2 facing the door lock front panel 1. Figure 2 , Figure 5As shown, the bottom end of the transparent protective film 9 passes downward through the two guide groove plates 10 in turn and is wound around another winding drum 8. A retaining frame 14 is fixedly installed on the side of the storage box 2 away from the magnetic door 3. The transmission shaft 6 on the same side is rotatably installed on the retaining frame 14. The position of the transparent protective film 9 corresponds to the position of the smart screen 101, the password fingerprint touch screen 102 and the camera assembly 103. In this embodiment, the replacement cycle of the coverage of the transparent protective film 9 can be set by the residents themselves. For example, if it is replaced in a cycle of three days, a ten-meter roll of transparent protective film 9 can be used for at least three months. Then the smart door lock transmission motor 5 reminds the residents to replace the winding drum 8 and the transparent protective film 9 through smart terminals such as mobile phones. At the same time, the transparent protective film 9 can be made of oil-repellent and dust-proof materials to reduce residual traces; specifically, the multifunctional smart door lock is provided with a transparent protective film 9 so that when the smart door lock is used daily, the transparent protective film 9 can be used. The transparent protective film 9 will cover one side of the door lock front panel 1, so that the smart screen 101 and the password fingerprint touch screen 102 are both located within the coverage of the transparent protective film 9. When the resident touches the password fingerprint touch screen 102 to enter the password or identify the fingerprint, the grease and dust on the fingertips will adhere to the transparent protective film 9 instead of the password fingerprint touch screen 102, thereby avoiding the password fingerprint touch screen 102 from leaving obvious marks due to long-term touch. At the same time, the transmission motor 5 inside the transmission box 4 will regularly drive the transmission shaft 6 to rotate, and then drive the transparent protective film 9 to rotate through the assembly drum 7 and the winding drum 8. The top winding drum 8 unwinds the new transparent protective film 9, and the bottom winding drum 8 winds up the used transparent protective film 9, thereby replacing the coverage of the transparent protective film 9 on one side of the door lock front panel 1, so that the transparent protective film 9 is often used and new, and the traces remaining on the transparent protective film 9 are prevented from affecting the safety performance of the smart door lock.

[0038] like Figure 6 As shown, mounting plates 11 are fixedly mounted at both ends of the transparent protective film 9. Figure 7 As shown, a second assembly hole 802 is provided on the side wall of the winding drum 8. Figure 8 As shown, a first assembly hole 701 adapted to the assembly plate 11 is provided on the side wall of the assembly cylinder 7. Figure 8As shown, the first assembly hole 701 is actually a bidirectional slot that passes through one side of the magnetic door 3, that is, when installing a new winding drum 8, the assembly plate 11 located inside the transparent protective film 9 and the first assembly hole 701 at the top are in a horizontal sliding plug-in, while the assembly plate 11 located outside the transparent protective film 9 and the first assembly hole 701 at the bottom are in a longitudinal sliding plug-in, so there is no obstacle to the installation of the assembly plate 11 on the new transparent protective film 9. The position of the first assembly hole 701 corresponds to the position of the second assembly hole 802. In this embodiment, the size of the second assembly hole 802 is larger than that of the first assembly hole. The size of the hole 701 is to facilitate the assembly plate 11 to pass through the second assembly hole 802; specifically, by setting the winding drum 8, when the transparent protective film 9 is used up and needs to be replaced, the magnetic suction door 3 on one side of the two storage boxes 2 can be opened, and then the assembly plate 11 at the top of the transparent protective film 9 is pulled out from the second assembly hole 802 and the first assembly hole 701 at the top, so that the top assembly plate 11 is separated from the assembly drum 7 and the winding drum 8, and then it is pulled out from the top guide groove plate 10 and slided into the bottom guide groove plate 10, so that it enters the top storage box 2, and then directly from the bottom storage box 2 Take out the winding drum 8 with the used transparent protective film 9, then take out the top winding drum 8, insert the winding drum 8 with the new transparent protective film 9 on the assembly drum 7, and make the second assembly hole 802 correspond to the position of the first assembly hole 701, so that the assembly plate 11 located inside the transparent protective film 9 slides along the first assembly hole 701 as the winding drum 8 and the assembly drum 7 are plugged, and then pull the assembly plate 11 located outside the transparent protective film 9 to slide through the two guide groove plates 10 in turn and enter the second storage box 2, and insert the original top winding drum 8 into the bottom assembly drum 7 On the top, make the second group of first assembly holes 701 and the second assembly holes 802 face each other, finally insert the assembly plate 11 into the second assembly hole 802 and the first assembly hole 701, and then close the two magnetic doors 3 to complete the replacement of the transparent protective film 9, so that the actual operation of replacing the transparent protective film 9 is simple, the process is short, and it will not take up too much time of the residents. At the same time, the winding drum 8 originally located at the top for unwinding can be sent to the storage box 2 at the bottom for winding up the new transparent protective film 9 after the old transparent protective film 9 is used up, without the need to add a winding drum 8, thereby saving the use of replacement materials.

[0039] like Figure 8 As shown, a plurality of ball grooves are provided on the inner wall of one side of the first assembly hole 701, and spring balls 12 are provided inside the ball grooves. A return spring is fixedly installed between the spring balls 12 and the inner wall of the ball grooves, as shown in FIG. Figure 6As shown, a plurality of snap-in holes 1101 matched with the spring balls 12 are provided on the side wall of the assembly plate 11; specifically, by providing the spring balls 12, when the assembly plate 11 is inserted into the second assembly hole 802 and the first assembly hole 701, the spring balls 12 on one side of the first assembly hole 701 will be pressed by the assembly plate 11 and shrink inward until the spring balls 12 are aligned with the snap-in holes 1101 and pop out, thereby snapping the assembly plate 11 into the first assembly hole 701, making the assembly plate 11 and the first assembly hole 701 more tightly connected, preventing the assembly plate 11 from slipping out of the first assembly hole 701 and the second assembly hole 802 at the bottom when the winding drum 8 is winding the transparent protective film 9, thereby causing the winding component to fail.

[0040] like Figure 8 As shown, the assembly plate 11 is made of magnetic material, and magnetic attraction plates 13 are fixedly installed on the inner walls on both sides of the first assembly hole 701. In the present embodiment, the magnetic attraction plate 13 is embedded in the inner wall of the first assembly hole 701; specifically, by setting the magnetic attraction plate 13, after the winding drum 8 is inserted into the first assembly hole 701, the spring ball 12 locks the assembly plate 11 in the first assembly hole 701, and the magnetic attraction plates 13 on both sides of the first assembly hole 701 will magnetically adsorb the assembly plate 11 made of magnetic material, thereby improving the stability of the assembly plate 11 being clamped in the first assembly hole 701, and enhancing the connection strength between the assembly plate 11 and the assembly cylinder 7.

[0041] like Figure 6 As shown, multiple evenly distributed reinforcing wires 15 are fixedly installed on both sides of the transparent protective film 9, and the multiple reinforcing wires 15 are distributed on both sides of the smart screen 101; specifically, by arranging the reinforcing wires 15, when the winding drum 8 at the bottom winds up the transparent protective film 9, the multiple reinforcing wires 15 on both sides of the transparent protective film 9 can enhance the tensile strength of the transparent protective film 9 itself, and prevent the surface of the transparent protective film 9 from being torn due to the pulling of the bottom when the transparent protective film 9 is wound up and unwound, thereby affecting the protective effect of the transparent protective film 9 and the normal operation of the subsequent winding and unwinding.

[0042] like Figure 5 As shown, a plurality of evenly distributed camera holes 901 are provided on one side of the transparent protective film 9, and the camera holes 901 are adapted to the camera assembly 103; specifically, by providing the camera holes 901, when the transparent protective film 9 is replaced, the reeling and unreeling length of the transparent protective film 9 is fixed, so that the camera holes 901 on the transparent protective film 9 and the position of the camera assembly 103 always roughly correspond, so that the front of the camera assembly 103 will not be covered by the transparent protective film 9, thereby preventing the transparent protective film 9 from affecting the clarity of the camera assembly 103.

[0043] like Figure 4As shown, both sides of the top and bottom of the door lock front panel 1 are fixedly installed with a pressing electric push rod 16, and the telescopic end of the pressing electric push rod 16 faces the transparent protective film 9 and is fixedly installed with a pressing claw 17, and the transparent protective film 9 is located between the pressing claw 17 and the door lock front panel 1; specifically, by arranging the pressing electric push rod 16, each time the covering surface of the transparent protective film 9 is replaced, the pressing electric push rod 16 will first be stretched and driven to make the pressing claw 17 separate from the surface of the transparent protective film 9, so as to avoid obstruction to the winding and unwinding of the transparent protective film 9. When the covering surface of the transparent protective film 9 is replaced, each pressing electric push rod 16 is simultaneously retracted and reset, so that the four pressing claws 17 are respectively stuck on the top and bottom sides of the covering surface of the transparent protective film 9, so that the transparent protective film 9 can be more closely attached to one side of the smart screen 101 and the password fingerprint touch screen 102, reducing the gap and improving the pressing touch of the residents.

[0044] like Figure 1 As shown, a cover shell 18 is movably sleeved on one side of the door lock front panel 1, and the door lock front panel 1, the storage box 2 and the transmission box 4 are all located inside the cover shell 18. Fig. 9 As shown, a panel hole 1801 is opened on one side of the outer shell 18, and the position of the panel hole 1801 corresponds to the position of the transparent protective film 9. A plurality of magnetic strips 19 are fixedly installed on the side of the outer shell 18 facing the door lock front panel 1; specifically, by setting the outer shell 18, the outer shell 18 is adsorbed on one side of the door lock front panel 1 by the magnetic attraction of the magnetic strips 19, and a part of the door lock front panel 1 and components such as the storage box 2 and the transmission box 4 are uniformly covered inside, which not only plays a role in protecting the internal components, but also improves the overall aesthetics of the front panel of the smart door lock. At the same time, the outer shell 18 will not cover the areas of the smart screen 101, the password fingerprint touch screen 102, the camera assembly 103 and the handle groove 104, and will not hinder the use of the functional areas of the door lock front panel 1, so there is no need to frequently disassemble the outer shell 18.

[0045] In summary: when in use: the transparent protective film 9 will cover one side of the door lock front panel 1, so that the smart screen 101 and the password fingerprint touch screen 102 are both located within the coverage of the transparent protective film 9. When the resident touches the password fingerprint touch screen 102 to enter the password or identify the fingerprint, the grease and dust on the fingertips will adhere to the transparent protective film 9 instead of the password fingerprint touch screen 102, thereby avoiding the password fingerprint touch screen 102 from leaving obvious marks due to long-term touch. At the same time, the transmission motor 5 inside the transmission box 4 will regularly drive the transmission shaft 6 to rotate, and then drive the transparent protective film 9 to rotate through the assembly drum 7 and the winding drum 8. The top winding drum 8 unwinds the new transparent protective film 9, and the bottom winding drum 8 winds up the used transparent protective film 9, thereby replacing the coverage of the transparent protective film 9 on one side of the door lock front panel 1, so that the transparent protective film 9 is often used and always new, and the traces remaining on the transparent protective film 9 are prevented from affecting the safety performance of the smart door lock.

[0046] Replacement of protective film: When the transparent protective film 9 needs to be replaced after it is used up, first remove the outer shell 18, press the electric push rod 16 to stretch it, so that the pressing claw 17 is separated from the surface of the transparent protective film 9 to avoid obstruction to the winding and unwinding of the transparent protective film 9, open the magnetic suction door 3 on one side of the two storage boxes 2, and then pull the assembly plate 11 at the top of the transparent protective film 9 out of the second assembly hole 802 and the first assembly hole 701 at the top, so that the top assembly plate 11 is separated from the assembly cylinder 7 and the winding cylinder 8, and then pull it out of the top guide groove plate 10. The reel 8 with the used transparent protective film 9 rolled up is taken out and slid into the guide groove plate 10 at the bottom, so that it enters the storage box 2 at the top, and then the reel 8 with the used transparent protective film 9 rolled up is directly taken out from the storage box 2 at the bottom, and then the reel 8 at the top is taken out, and the reel 8 with the new transparent protective film 9 rolled up is inserted into the assembly cylinder 7, and the second assembly hole 802 is made to correspond to the position of the first assembly hole 701, so that the assembly plate 11 located inside the transparent protective film 9 is inserted along the first assembly hole 701 along with the insertion of the reel 8 and the assembly cylinder 7, and then the assembly plate 11 located inside the transparent protective film 9 is pulled out. The assembly plate 11 outside the protective film 9 is made to slide through the two guide groove plates 10 in sequence and enter the second storage box 2, and the original top winding drum 8 is inserted into the bottom assembly drum 7, so that the second group of first assembly holes 701 and the second assembly holes 802 are opposite to each other, and finally the assembly plate 11 is inserted into the second assembly hole 802 and the first assembly hole 701, and the spring ball 12 on one side of the first assembly hole 701 will be pressed by the assembly plate 11 and shrink inward until the spring ball 12 is aligned with the clamping hole 1101 and pops out, thereby the assembly plate 1 1 is snapped into the first assembly hole 701, so that the assembly plate 11 and the first assembly hole 701 are more tightly plugged, and then the two magnetic doors 3 are closed to complete the replacement of the transparent protective film 9. At this time, each pressing electric push rod 16 shrinks and resets at the same time, so that the four pressing claws 17 are respectively stuck on the top and bottom sides of the cover surface of the transparent protective film 9, so that the transparent protective film 9 can be more closely attached to one side of the smart screen 101 and the password fingerprint touch screen 102, reducing the gap and improving the pressing touch of the residents. Finally, the outer shell 18 is installed to complete the replacement.
