Description

Technical Field

[0001] The utility model relates to the field of contactless face recognition door locks, and more specifically, the utility model relates to a contactless face recognition door lock. Background Art

[0002] Most contactless door opening systems are realized by intelligent door locks. An intelligent door lock refers to an intelligent control door lock improved on the basis of a traditional mechanical lock, which has more intelligent and simple features in terms of user security, identification, and management. The intelligent door lock uses a non-mechanical key as a user identity recognition solution and is widely used in places such as banks, government departments, hotels, school dormitories, residential communities, villas, and guesthouses.

[0003] Chinese Patent CN208460085U discloses a face recognition lock based on a distributed camera array, which includes an intelligent door lock and a mobile terminal. The intelligent door lock includes a human body infrared induction module, a face recognition module, a wireless communication module, a main controller, and a mechanical lock device. The intelligent door lock is also provided with a distributed camera array, which contains several cameras, and the several cameras are longitudinally arranged along a certain arc. Due to the adoption of the above technology, in the utility model, multiple camera arrays are distributed and installed in the door lock, and the images collected by the multiple camera arrays are obtained through a high-precision stitching algorithm to obtain an image containing a complete face for face detection and recognition, thereby avoiding the limitations of existing face recognition door locks for users of different heights and effectively solving the problem of face recognition limitation due to height, and finally achieving the purposes of effectively expanding the face recognition range and meeting the needs of users of a wider range of heights.

[0004] However, in actual use, the installation height of existing intelligent door locks is generally lower than that of ordinary adults. When face scanning and recognition are required, semi-squatting is needed to make the position of the face correspond to the camera on the intelligent door lock for face capture, which increases the trouble during unlocking. Summary of the Utility Model

Specific embodiments

[0023] The utility model provides a touchless face recognition door lock as Figures 1-4 shown, comprising:

[0024] A door lock main body 1, a handle 11 is installed on the front outer surface of the door lock main body 1, and a storage groove 23 is opened above the handle 11 on the front outer surface of the door lock main body 1;

[0025] A face recognition terminal 2, the face recognition terminal 2 is arranged inside the storage groove 23, both sides of one end of the face recognition terminal 2 are fixedly installed with rotating shafts 22, and the face recognition terminal 2 is rotationally connected to the inner wall of the storage groove 23 through the rotating shafts 22, and a camera 21 is fixedly installed on the front outer surface of the face recognition terminal 2;

[0026] A bracket 3, the bracket 3 is arranged at the rear end of the face recognition terminal 2, and the bottom end of the bracket 3 is hinged to the rear outer surface of the face recognition terminal 2.

[0027] In a preferred embodiment, as Figures 1-2 shown, a chute 12 is opened on one outer surface of the door lock main body 1, a sliding button 32 is arranged on one outer surface of the door lock main body 1, and the sliding button 32 is inserted into the chute 12, a plurality of grooves are opened on the inner wall of the chute 12, and a convex block 33 matching the grooves is integrally arranged on one outer surface of the sliding button 32.

[0028] In a preferred embodiment, as Figures 3-4As shown, one side of the top end of the bracket 3 is fixedly installed with a connecting pipe 31. An inner rod 34 is arranged inside the connecting pipe 31. One end of the inner rod 34 is fixedly connected with one end of a sliding button 32. One end inside the connecting pipe 31 is fixedly installed with a retaining ring 35. The retaining ring 35 is sleeved on the outer surface of one end of the inner rod 34, and the inner rod 34 is slidably connected with the retaining ring 35. The other end of the inner rod 34 is fixedly installed with a baffle 36. A return spring 37 is sleeved on the outer surface of the inner rod 34 on one side of the baffle 36. By driving the connecting pipe 31 to slide downward through the sliding button 32, one end of the bracket 3 is driven to push outward, and the face recognition terminal 2 is pushed out of the storage groove 23 for unfolding. During the process of pulling the sliding button 32 outward, the inner rod 34 will be driven to slide along the retaining ring, so that the baffle 36 at one end squeezes the return spring 37.

[0029] Working principle of the utility model:

[0030] Referring to the attached Figures 1-4 When unlocking, the camera on the face recognition terminal 2 can capture and identify the user's face. When the face recognition terminal 2 needs to be unfolded and adjusted, the sliding button 32 on one side can be pulled outward first, driving one end of the sliding button 32 to disengage from the sliding groove 12, so that the two convex blocks 33 disengage from the grooves engaged with the inner wall of the sliding groove 12, releasing the limit on the sliding button 32. Then, by driving the connecting pipe 31 to slide downward through the sliding button 32, one end of the bracket 3 is driven to push outward, and the face recognition terminal 2 is pushed out of the storage groove 23 for unfolding. During the process of pulling the sliding button 32 outward, the inner rod 34 will be driven to slide along the retaining ring, so that the baffle 36 at one end squeezes the return spring 37. After the angle of the face recognition terminal 2 is adjusted, the sliding button 32 is released, and the return spring 37 will pull the inner rod 34 inward to reset, driving the convex block 33 on the surface of the sliding button 32 to insert into the groove at the corresponding position of the sliding groove 12.
