The guiding portion 50 is slid on the first trajectory 62 or the second trajectory 63. The second trajectory 63 is a specially designed trajectory. The purpose is to first drive the fourth flail 40, then link the other links, and finally rotate the second link. 20 to adjust the photography 201102751 machine 1 camera angle. When the pivot angle Θ is not a specific angle range, the guide 50 is slid along the first track; when the pivot angle < 9 is within a certain angle range (in this In the embodiment, between 70 degrees and 155 degrees, the guiding portion 50 is slid along the second trajectory, and the pivoting angle of the second link 20 is controlled by the second trajectory 63 of the cam 60. Yes, the shapes of the first track 62 and the second track 63 are not limited to the above. For example, when the camera 1 is mirrored The second track 63 may also be different when the height or angle of the head is different. It should be noted that the structure of the guiding portion 50 is not limited to the above. For example, the cam 60 of the guiding portion 50 may be modified. The same effect can be achieved by using a member such as a slide rail having an annular groove. It should be noted that in the camera adjustment mechanism 100, since the first link 10 is directly fixed to the cover 210, both can be There is no substantial relative motion, so the first link 10 can be omitted or the cover 210 can be directly replaced by the cover 210, and the first end 101 and the second end 102 of the first link 10 can be directly fixed to the first end 101. The corresponding position in the cover 210 (not shown). Further, the first pivoting portion of the second link is pivotally connected to one side of the cover, and the first end of the third link is pivotally connected to the other side of the cover. As for the rest of the structure, it can be the same as the foregoing embodiment. Next, please refer to FIG. 3 to FIG. 7 together to explain the actual operation mode of the embodiment of the camera adjustment mechanism of the present invention in stages. 4 is a schematic view of the angle between the cover and the main body at 45 degrees, FIG. 5 is a schematic view when the angle between the cover and the main body is 70 degrees, and FIG. 6 is a schematic view when the angle between the cover and the main body is 110 degrees, FIG. It is a schematic diagram when the angle between the cover and the main body is 155 degrees. (1) Figure 3 moves to the stage of Figure 4. 9 201102751 At this time, the cover 210 of the portable electronic device 200 is moved from the fully closed state (as shown in FIG. 3) to the rotational direction d1 to adjust the pivoting angle Θ1 (45 degrees in this embodiment) to FIG. In this state, the guiding portion 50 of the guiding device 5 is slid on the first trajectory 62 at this time. In this embodiment, a specific angle is set to 70 degrees, and the pivot angle Θ1 (ie, 45 degrees) of FIG. 4 has not reached 70 degrees, and the rotation angle 0 1 of the cover 210 relative to the body 220 is substantially equal to the camera 1 The lens is rotated at an angle of 0 1 (ie 45 degrees). At this time, the orientation of the camera 1 cannot be aligned with the target. The camera 1 of Fig. 4 is not in a normal use state because the pivot angle 01 is too small. (2) Figure 4 moves to the stage of Figure 5. At this time, the cover 21 of the portable electronic device 200 continues to rotate by the pivoting angle 02 from the state shown in FIG. 4 toward the rotational direction d1 (in this embodiment, 2 moves to the state shown in FIG. 5, at this time, the guiding portion 5 〇 also slides $ on the first striker 62, and the lens orientation of the camera 1 also rotates by Θ2 (ie 25 degrees). At the stage of Figures 3 to 5, the cover 21 〇 has the same rotation angle with respect to the body 22〇 The angle of rotation of the lens of the camera 1 is that there is no relative rotation between the cover 210 and the camera 1. In the state of FIG. 5, the corner η between the cover 21〇 and the body 22〇 is at a specific angle ( That is, 7 degrees), at this time, the guiding portion 5 〇 is located at the position 61 (ie, the junction between the first-deletion 62 and the second trajectory 63), and at this time, the camera 匕 imaging angle is toward the target (for example, the head of the user) Part or eye area (3) Figure 5 moves to the stage of Figure 6. 201102751 The cover 210 of the portable electronic device 200 continues to be moved from the state shown in Figure 5 to the rotational direction d1 by a pivoting angle of 0 3 (e.g., 40 degrees) to The state shown in Fig. 5 is such that the pivoting angle 0 between the cover 210 and the body 220 is 110 degrees. At this time, the pivoting angle 0 is already Within the range of angles (ie, between 70 degrees and 155 degrees), wherein the guiding portion 50 starts to slide on the second track 63, and the fourth link 40 is driven by the protruding portion of the second track 63, and then by other Under the driving of the connecting rod, the second connecting rod 20 is interlocked, so that the second connecting rod 20 is rotated, so that the lens of the camera 1 faces the actual rotating angle 04 much smaller than the rotating angle Θ 3 (because the second trajectory 63 The radius of curvature is relatively flat compared to the radius of the first trajectory, as shown in Figure 6, and the lens of camera 1 can still be substantially maintained toward the target (such as the user's head or eye area). 4) Figure 6 moves to the stage of Figure 7. The cover 210 of the portable electronic device 200 continues to move from the state φ shown in Figure 6 to the rotational direction d1 by a pivot angle Θ 5 (e.g., 45 degrees) to the state shown in Figure 7. The pivoting angle 0 between the cover 210 and the body 220 is 155 degrees. At this time, the pivoting angle 0 is at a boundary of a specific angular range (ie, between 70 degrees and 155 degrees). At this time, the camera 1 is made The actual rotation angle of the lens orientation 0 6 is still smaller than the rotation angle 05 (because the guide 50 Still sliding on the second trajectory 63, as shown in FIG. 7), the lens of the camera 1 is continuously maintained toward the target without excessive angle change. At the stage of FIGS. 5 to 7, the cover 210 is opposite to the lens 210. The rotation angle of the body 220 is different from the rotation angle of the lens of the camera 1, so that the photography 201102751 maintains the lens of the camera 1 of the camera 1 toward the target, and the overall mechanism of the present invention is portable. The electronic machine adjustment mechanism and the camera adjustment, so that the fourth link is simultaneously connected to the rod and the third link between the three links and the fourth link by the link group (for example, four links) Turn 'and the trace, step-by-step to drive the camera to rotate ^丨: limited by the cam == when the cabinet is opened, the user does not need S = _ degrees and 155 degrees:) Hold the same camera angle.
