Detailed description of the invention
With detailed description of the invention, this utility model is further elaborated below in conjunction with the accompanying drawings.
Embodiment 1
Refer to Fig. 1 to Fig. 3, for preferred embodiment of the present utility model.The present embodiment the laser ranging module 1 of adjustment can include that pedestal 11, generating laser 12, generating laser fix lid 13, camera lens 14, lens eccentricity set 15, circuit board 16, filter plate 17, optical pickocff 18 and screw 19.
Generating laser 12 is installed on the base 11, fixing on the base 11 by the fixing lid of generating laser 12；Camera lens 14 includes lens 141 and lens case 142, camera lens 14 is arranged on lens eccentricity set 15, between camera lens 14 and generating laser 12, shape is at a certain angle, and the laser signal that generating laser 12 sends pools as to optical pickocff 18 through camera lens 14 after external object 2 reflects；The receiving space (unmarked) accommodating lens eccentricity set 15 is formed on pedestal 11, lens eccentricity set 15 is fixing on the base 11 by screw 19, it is specially and is formed on pedestal 11 surface and accommodate the screwed hole that space connects, then screwed hole is passed through to be fixed on pedestal (lens eccentricity set 15 also can be fixed on pedestal, such as glue by other means) by lens eccentricity set 15 by rotary screw 19；Filter plate 17, for the laser signal of filter specific wavelengths, is positioned at after camera lens 14；Optical pickocff 18 is installed on the board 16, is positioned at after filter plate 17, and optical pickocff 18 can use CCD or cmos image sensor；Camera lens 14, filter plate 17 and optical pickocff 18 are the most point-blank.
Owing to described lens 141 are eccentrically mounted in lens case 142, and described lens 141 can be relatively around the central rotation of described lens case 142, the circle that the axle center of described lens 141 is formed in rotation is positioned at the induction region of described optical pickocff 18, so, by the rotation to described lens 141, the primary optical axis making described lens 141 can be adjusted with vertical direction in the horizontal direction relative to pedestal 11, overcomes the precision defect that alignment error is brought.
As shown in Figure 6, Figure 7, lens eccentricity set 15 in the present embodiment includes knob 151 and locating dowel 152, knob 151 surrounding forms the rotary teeth 154 facilitating rotary knob 151, locating dowel 152 is in cylinder, and it is provided with through hole (not shown) in described locating dowel 152, middle eccentric setting has the camera lens installing hole 153 being substantially round in shape, i.e. the most on the same axis, the axle center of described lens 141 is positioned at described through hole in the center of circle (center of circle of described through hole) of the center of circle of camera lens installing hole 153 and locating dowel 152.Therefore, when rotary knob 151, the primary optical axis of lens 141 can vertically and horizontally offset, and makes the laser signal after reflection pool as the situation of deviation optical pickocff 18 is corrected.
Citing below illustrates, as shown in Figure 4, owing to manufacturing or assembling reason, can the primary optical axis O of lens 141 of laser ranging module 1 of adjustment not on the horizontal axis A-A of generating laser 12；As it is shown in figure 5, by by after lens eccentricity set 15 half-twists counterclockwise, the primary optical axis O of lens 141 is located on the horizontal axis A-A of generating laser 12, and the center O of camera lens 14 also offset by certain distance to the right simultaneously.
Embodiment 2
As shown in Fig. 8 to Figure 10, for embodiment 2 of the present utility model.The present embodiment 2 is substantially the same manner as Example 1, different places is, this utility model the laser ranging module of adjustment can not have lens eccentricity set, the lens 141 of camera lens 14 are eccentrically set in lens case 142, i.e. the center of circle of the center of circle of lens 141 and lens case 142 is the most on the same axis, therefore lens 141 can be made to be adjusted at above-below direction and left and right directions by rotating lens case 142.
It is above the detailed description of preferred embodiment of the present utility model, it is impossible to assert that this utility model is confined to these explanations.For this utility model person of an ordinary skill in the technical field; equivalent done without departing from the concept of the premise utility substitutes or substantially deforms; and performance or purposes identical, all should be considered as in the protection domain that claims that this utility model submitted to determine.
