[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] like Figure 1-7 As shown, a new type of anti-theft identification intelligent door lock includes a shell 1, a handle 11, and a lock tongue 12 linked to the handle 11. The side of the shell 1 close to the outside is an outer surface 13, and a cavity 14 for accommodating is arranged inside; the outer surface 13 is provided with a groove 2, and a password identification device 3 is installed in the groove 2. The password identification device 3 can be a password key or fingerprint recognition. A cover plate 4 is movably installed in the groove 2, and a driving device and a linkage structure are installed in the cavity 14 to automatically open and close the cover plate 4 and thus cover or expose the password identification device 3; a top touch switch 7 for controlling the password identification device 3 is also installed in the cavity 14. The driving device drives the cover plate 4 to open through the linkage structure and the linkage structure presses on the top touch switch 7 to start the password identification device 3. Of course, when the linkage structure does not contact the top touch switch 7, the password identification device 3 is not started. The top touch switch 7, the password identification device 3, and the driving device are all electrically connected to a control circuit board 9 installed in the cavity 14. The housing 1 is installed on one side of the room with a motor switch 61 for controlling the start of the drive device. The motor switch 61 can be installed in a hidden place, such as Figure 7 As shown, it is installed behind the handle 11, and of course it can also be installed on the top of the housing 1, etc. The drive device can also be connected and controlled by the control circuit board 9 and the mobile terminal APP.

[0032] Embodiment 1:

[0033] like Figure 1-3As shown, the cover plate 4 adopts a closed structure that moves up and down to open the groove 2. A sliding cavity adapted to the cover plate 4 is provided at the top of the groove 2, and at least one vertical sliding groove 5 connected to the sliding cavity is provided on the inner wall of the cavity 14; the linkage structure includes a linkage rod 51 installed on the cover plate 4, which passes through the sliding groove 5 and extends to the cavity. The driving device adopts a linear motor 6. The linkage rod 51 moves up and down along the sliding groove 5 through the linear motor 6 installed in the cavity 14, thereby driving the cover plate 4 to move up and down to open and close the groove 2. A touch block 71 that cooperates with the top touch switch 7 is installed on the top of the linkage structure, and the top touch switch 7 is located directly above the touch block 71. Reference Figure 3 , the trigger block 71 is installed on the screw rod of the first connecting rod 52, and of course it can also be installed on the linkage rod 51. Here, the cover plate 4 is divided into a closed mode and an open mode. In the closed mode, the linear motor 6 drives the linkage rod 51 to move downward and then moves the cover plate 4 downward along the sliding cavity to close the groove 2. In this way, the password recognition device 3 in the groove 2 is blocked by the cover plate 4, and people cannot directly contact the password recognition device 3, and children cannot play and damage the password recognition device 3 in the groove 2. Similarly, criminals cannot open the door with a stolen password, which improves the safety performance of the door lock. And because in the closed mode, the linear motor 6 is in the lower state, the trigger block 51 does not contact the top touch switch 7, even if the cover plate 4 is violently disassembled, the password recognition device 3 is in a power-off or unstarted state, and people with the password cannot open the door lock. When the closed mode is changed to the open mode, the linear motor 6 can be started by pressing the motor switch 61 on the indoor side or by using the APP of the mobile terminal. At this time, the linear motor 6 drives the linkage rod 51 to move upward and then drives the cover plate 4 to move upward along the sliding cavity, opening the groove 2 to expose the password recognition device 3. At the same time, the linkage rod 51 moves upward and its top will touch the top touch switch 7 to open the password recognition device 3. In this way, the password can be unlocked normally.

[0034] In general, two parallel slides 5 are provided, and the linear motor 6 is installed between the two slides 5. One end of the linkage rod 51 in the two slides 5 extending out of the cavity 14 is connected by a first connecting rod 52, and the middle of the first connecting rod 52 is fixed on the linear motor 6. When the linear motor 6 moves up and down, it is driven by the first connecting rod 52 to drive the linkage rod 51, which is more stable during the entire operation process.

[0035] Embodiment 2:

[0036] like Figure 4-6As shown, the cover plate 4 adopts a flip-up structure, and one side of the cover plate 4 is rotatably mounted on a side of the groove 2 close to the cavity 14 with the side as the rotation axis, and at least one vertical through slot 8 connected to the groove 2 is opened on the inner wall of the cavity 14; the linkage structure includes a swing rod 81 installed on the rotation axis and extending through the through slot 8 to the cavity 14, and the driving device adopts a linear motor 6. The swing rod 81 is driven by the linear motor 6 installed in the cavity 14 to move up and down, and then the cover plate 4 is turned up and down with the rotation axis as the axis to cover and expose the password identification device 3. A touch block 71 that cooperates with the top touch switch 7 is installed at the bottom of the linkage structure, and the top touch switch 7 is located directly below the touch block 71. Similarly, in the closed mode, the linear motor 6 drives the swing rod 81 to move upward. Since one end of the cover plate 4 is rotatably installed in the groove 2 with one side as the rotating shaft, the other end of the swing rod 81 tilts up to drive the cover plate 4 to flip downward to cover the identification device. At this time, the top touch switch 7 is separated from the touch block. Even if the cover plate 4 is forcibly disassembled, the password identification device 3 is in an unopened state. In the open mode, the linear motor 6 drives the swing rod 81 to move downward, and the other end of the swing rod 81 drives the cover plate 4 to tilt up to expose the password identification device 3. At the same time, the touch block 71 contacts the top touch switch 7 to open the password identification device 3, which can be used normally.

[0037] Similarly, two through slots 8 can also be provided in parallel, and the linear motor 6 is installed between the two through slots 8. The ends of the swing rods 81 in the two through slots 8 extending out of the cavity 14 are connected by a second connecting rod 82, and the middle of the second connecting rod 82 is fixed on the linear motor 6. Since the swing rod 81 is fixed at one point, the horizontal position of the end close to the cavity 14 will change during its up and down movement, so a movable slot 811 is provided on the end of the swing rod 81 close to the cavity 14, and sliding pins 821 embedded in the movable slot 811 are installed at both ends of the second connecting rod 82. In this way, when the horizontal position of the end of the swing rod 81 close to the cavity 14 changes, the movable pins at both ends of the second connecting rod 82 can slide in the movable slot 811 to complement each other.

[0038] The above is only a preferred specific implementation of the present invention; however, the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and its improved conception within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
