Specific embodiment
In conjunction with Fig. 1, Fig. 2, a kind of mobile phone recognition of face structure light bracket offers the first hole location 10, the second hole location 20,
Three hole locations 30, the 4th hole location 40, any hole location matching design have hardware accommodating chamber, are equipped between hardware accommodating chamber and corresponding hole site
Position limiting structure.
Such as Fig. 3, it is connected to before and after any hole location and corresponding hardware accommodating chamber, the internal diameter of any hole location holds less than corresponding hardware
Receive the internal diameter of chamber, in this way, forming step between any hole location and corresponding hardware accommodating chamber, which becomes the limit knot
Structure.Hardware is packed into hardware accommodating chamber by the rear of bracket, terminates in the position limiting structure, corresponding hole location is protruded into the front end of hardware
In.
First hole location 10 and corresponding hardware accommodating chamber are for installing infrared lens；Second hole location 20 and corresponding
Hardware accommodating chamber be used for installation point array projection device；The third hole location 30 and corresponding hardware accommodating chamber are for installing floodlight sense
Answer element；4th hole location 40 and corresponding hardware accommodating chamber are for installing earpiece.
Such as Fig. 2, any corresponding hardware accommodating chamber of hole location is square, and rectangular four corners are equipped with semicircular accommodation groove
12, the projected square part of hardware cooperates in hardware accommodating chamber, and quadrangular fit is in corresponding semicircle accommodation groove, the semicircle
Accommodation groove can absorb in mobile phone use process because of hardware deformation or deformation of timbering caused by expanding with heat and contract with cold.
The top edge 13 of first hole location 10 and the arc-shaped shape of lower edge 14, the left edge 15 and right hand edge 16 of the first hole location are in
The front end portion of spill, infrared lens is rounded, cooperates in the first hole location, the lower edges of the first hole location and infrared lens
Front end portion is fitted close, and the front end portion clearance fit of the left and right edges of the first hole location and infrared lens, in this way, the first hole
The change that the left and right edges of position can effectively absorb the front end portion of infrared lens, mobile phone recognition of face structure light bracket generates
Shape.
In conjunction with Fig. 1, Fig. 2, Fig. 4, it is equipped with several first positioning columns 51 before bracket, is equipped with behind bracket several
Second positioning column 52, the front and back of bracket is uneven, puts down on the front end face and bracket of the first positioning column near preceding
