The cam path surface '118承载, the bearing surface 119 and the first mating surface 116 m: the segment, the starting point to the end point of the path surface 118 is the same as the end point 'll face = the same amplitude' and each segment of the cam path surface 118 is Ο 目Each of the first mating surfaces 116 has an inclination g path = a starting point to an end point on the surface 5 - the position is inclined with respect to the same direction, and as seen from FIG. 1 , it is a counterclockwise rise = pair: = segment 2 path Each of the faces of the cams in the face 118 = ΐίΐίΐΓ 16 can be set to ί -=^ according to the accuracy requirements. The three-stage cam path surface 118 or the like is distributed in the lens barrel 12 and is received in the lens holder u, which is fixed to the side; the far side; the side is the side, and has the second outer thread The inner cylinder 120 is fixed to the second body 1210 of the outer m by the cooperation of the second external thread 120 (4). The first frame body 121 has a first lens barrel 12 farthest from the side of the lens holder n, and is parallel to each other; 1210, 1213 ί^; 2^: a person's beard hides and hides, thereby driving and calling the mirror座ι;^ 6 201038993 1*1210^1—The homomorphic mi is also a hollow cylinder, which is the second f of the first cylinder, Ϊ 'and is directly from the diameter of the first cylinder (four). The first receiving cavity 114 is disposed on the first receiving body 114. The surface 1215 and the second mating surface 1216 are parallel to the first end surface 1213 of the second end surface m61. The second matching n'/shi is parallel and parallel with the first mating surface 116.

In this embodiment, the shape is also substantially an arc shape, and the convex surface 1220 is a hemispherical surface. =' The bump ms may also be a hemisphere or other irregular shape, and only u has a convex surface 122 that protrudes toward the first mating surface 116. Of course, the inner cylinder 120 and the outer cylinder 121 may be integrally formed, and the inner body 120' may be omitted to directly receive the optical component in the outer cylinder. The cover 13 is fixed to the mirror base u. It includes a connected side 130 and a bottom wall 131. The side wall 13 has a first internal thread 132 matched with the first two threads 115 of the lens holder n, and the cover body is fixed to the lens holder by the cooperation of the first line 132 and the first external thread 115. The first body 110 of 11. The bottom wall 131 is opposite to an end surface 1217 of the second cylinder 1211 of the lens barrel 12, and has a through hole 133 for the first cylinder of the barrel 12 of the lens barrel 12 to pass through, thereby being first The operation of the cylinder 121〇 201038993 The cup 1214 can also pass through the through hole 133 and move in the through hole 133. The elastic member 14 is located at the cover body 13 and the mirror is 轴向 Ϊϋ Ϊϋ 。. The elastic 70 member 14 in this embodiment w is a spring piece which is substantially annular and includes a frame 14G of a 圊% shape and at least two are connected to the frame 14()^ 141. The number of the elastic arms 141 is three, and is distributed around the elastic member. Each of the elastic arms 141 has a connecting end (10) and an I extending 143. The connecting end 142 is connected to the frame body 14 , and the extending end 143 ❹ Ο f is from the frame W 〇 along the axis of the lens holder 11 to the remote body 140. The direction is extended such that when the elastic member 14 is in a natural state, each of the elastic arms Mi is at a right angle. The frame i 40 of the elastic element * 14 is sleeved outside the first cylinder 121 and bears against the second end of the second cylinder 12 = 12 ^ the extended end 143 of the elastic arm 141 and the cover 13 Convicted with sin. When the S elastic member 14 is compressed, the elastic arm 141 is deformed, and the cymbal is less than the plane of the frame 140. When the pressure is t, the arm 141 and the frame H 14 夹 are sandwiched between the planes. The angle is restored to its original angle. Of course, the resilient element 14 can also be a spring, an elastomeric pad or other alternative. The glass piece 15 is oppositely disposed on a side of the lens barrel 12 away from the lens holder 11, and has a rail 15?. The rail 15 is an arcuate through hole 'opening in the glass sheet 15 for passing the operating rod 1214 and restricting the angle θ at which the operating rod 1214 is rotated relative to the central axis of the mirror holder u. The track 150 has opposing first and second ends 151, 152. When the operating lever 1214 is located at the first end 151 of the track 15〇, the projection 1218 is located at the = mating face 116' and the resilient member 14 is in a natural state. In the present embodiment, the center angle θ of the track 150 corresponding to the central axis of the mirror holder u is 30. . The glass sheet 15 can be bonded to the shell of the face group by bonding or the like. Please refer to FIG. 1, FIG. 4 and FIG. 5, and when the focus lens module 1 is moved to the second end portion 152, the lens barrel = 1214 is along the obstruction 150 and the cam path surface 118 of the protrusion 117. The convex path of the f12 is the cam path of the protrusion 117. The 118 path is raised and stepped on, and the protrusion 1218 is opened upward and the ${§ elastic element μ彳φ disc_,}·the arm 14! is deformed until the bump is made. The convex arm 141 protrudes from the bearing surface II9, and the elastic arm 141 reaches and carries the Dingping Note # 141 and the frame 140 in the plane of the needle contact = the small 1 and the 12 and the lens holder 11 along the lens holder. 11 Axial ❹ The distance between the image sensor and the lens of the lens holder 11 and the lens barrel 12 is also increased to achieve focusing. It can be understood that the multi-segment focusing of the focus lens module 10 can also be achieved if the protrusions 117 are omitted from the stepped configuration and the plurality of cam path surfaces are disposed accordingly. The focus lens module 10 of the 117 case realizes the change of the relative position between the lens barrel 12 = the seat 11 by the interaction between the protrusions imaginary projections 1218 of the lens holder 11, since the protrusion 117 has the cam path 镜 barrel 12 It can slide smoothly with respect to the lens holder 11 during focusing. The elastic member 14 can prevent the lens barrel 12 and the lens holder u from being misaligned. The mirror assembly 1G of the present invention is not only simple in structure, but also takes up two small sizes, which is suitable for the current miniaturization of the lens module, and the cost. Low cost, especially suitable for electronic products such as mobile phones. _ In summary, the present invention has indeed met the requirements of the invention patent, and the patent towel is required in accordance with the law. However, the above is only an exemplary embodiment of the present invention, and it is not possible to limit the scope of the patent application in this case.
