Specific embodiment
Embodiments of the present invention are illustrated by particular specific embodiment below, those skilled in the art can be by this specification
Revealed content is understood other advantages and efficacy of the present invention easily.Although description of the invention will combine preferred embodiment
It introduces together, but this feature for not representing the invention is only limitted to the embodiment.On the contrary, being invented in conjunction with embodiment
The purpose of introduction is to be possible to the other selections extended or transformation to cover based on claim of the invention.In order to mention
For that will include many concrete details in depth understanding of the invention, being described below.The present invention can also be thin without using these
Section is implemented.In addition, in order to avoid confusion or obscuring emphasis of the invention, some details will be omitted in the de-scription.
As shown, the embodiment provides a kind of face identification device of adaptive height, including identification control
Portion 1 processed, the identification control unit 1 include recognition control circuit plate 11 and carry out light filling for the head portrait to user and seek to face
Look for, capture, positioning, identifying the camera assembly 12 of image zooming-out.Camera assembly 12 mainly includes mounting rack 121 and is mounted on installation
121 positive two cameras 122 of frame, are additionally provided with light compensating lamp 123, the mounting rack 121 be equipped with focused lamp cover 124 with it is described
Light compensating lamp 123 cooperates, and 121 side of mounting rack, which is stretched out, is equipped with 132 hole 125 of output shaft, and the other side is equipped with and 132 hole of output shaft
125 coaxial driven shafts 126；Driving assembly 13 is used to drive camera assembly 12 to rotate upwardly and downwardly when carrying out face searching, drives
The main output shaft 132 for including the motor 131 of output power and being driven by motor 131 of component 13, the output shaft 132 and motor
131 can be to be directly connected to or be indirectly connected with by drive mechanism；The matching of output shaft 132 is inserted into 132 hole 125 of output shaft simultaneously
The mounting rack 121 is driven to rotate centered on 132 hole 125 of output shaft and driven shaft, to drive the camera 122
The increase of camera 122 image pickup scope and recognition of face range is realized in rotation.
In other words, as long as the height of head of user is when camera 122 rotates, in its minimum rotation angle and highest rotation angle
Within the scope of, head portrait can be captured by camera 122, bend over without user or the padded face that can fast implement is known
Not.It is connected using 121 side of mounting rack for being provided with camera 122 with driving assembly 13, when mounting rack 121 is in driving assembly
When under 13 driving with the axial rotation of side, the positive camera 122 of mounting rack 121 also carries out turning in up and down direction therewith
It is dynamic, it is matched with the direction of Human Height.
As the preferred embodiment that driving assembly 13 is driven, the driving component 13 further includes pinion unit, described

152, when the limited post 152 is mounted on the gear-box 15, the limited post 152 be inserted into first limiting slot 141 or
In second limiting slot 143, limited post 152 is as the rotation of the tumbler gear is in first limiting slot 141 or the second limit
It is slided in the range of slot 143.
The lead limitation that cooperatively formed of first limiting slot 141 and the second limiting slot 143 and limited post 152 cooperates, so that
Camera assembly 12 can only be rotated up and down in a preset angular range.In view of what can independently be unlocked using recognition of face
Height ranges are 1.2-1.9m, the mounting height with Generic face identification door lock, by the range of the first limit angle in the present embodiment
+ 15 °~-45 ° are preferably arranged to, the range of the second limit angle is preferably arranged to+45 °~-15 °, and guarantee can be by this height model
User's head in enclosing is covered in the identification range of camera 122.
Two kinds of limit angles provide the locality that two kinds of this face identification devices can be installed, specific structure and user
Method are as follows: anchor point is additionally provided on tumbler gear, matching with first limiting slot 141 and being located at the same face is the first positioning
Point, matching with second limiting slot 143 and being located at the same face is the second anchor point 146.When first limiting slot 141
When installing towards limited post 152, chalaza is corresponding, and limited post 152 will be inserted into matching on gear-box 15 for first anchor point
In first limiting slot 141 so that final camera assembly 12 rotates between+15 °~-45 °, at this time the case where be suitable for face and know
Other device is inversely installed.When the second limiting slot 143 is installed towards limited post 152, second anchor point 146 and gear-box 15
On it is corresponding with chalaza, limited post 152 will be inserted into the second limiting slot 143 so that final camera assembly 12+45 °~-
It is rotated between 15 °, is suitble to face identification device just setting installation at this time.It just sets installation and two ways is inversely installed considering
When cooperating with the other structures of door lock, various structures scheme and external styling can be designed, the diversity of door lock is increased.
The angle that camera 122 turns to needs the detection by angular transducer 16, in order to more accurately capture steering
Angle, enhancing structure integraty and degree of protection sensor 16 from external world, the present embodiment sets angular transducer 16
It is placed in gear-box 15.The angular transducer 16 is equipped with bayonet 161 and connection jaws 162, and the bayonet 161 is used for so that institute
