S=|L1-L2|; When the distance L1 that the first reflective component 4202 moves in the third direction Z is less than the distance L2 that the second reflective component 4203 moves reversely in the third direction Z, the light rays pass through the image sensor 4204 The imaging position on is deviated in the negative direction of the first direction X by S=|L1-L2|. When the first reflective component 4202 and the second reflective component 4203 move in opposite directions in the third direction Z so that they are close to each other, when the distance L1 moved by the first reflective component 4202 in the third direction Z is greater than the second When the reflective component 4203 moves reversely by the distance L2 in the third direction Z, the imaging position of the light on the image sensor 4204 deviates in the negative direction of the first direction X by S=|L1-L2|; the first reflective component When the distance L1 that 4202 moves in the third direction Z is less than the distance L2 that the second reflective component 4203 moves reversely in the third direction Z, the light S=|L1-L2| deviates S in the positive direction of the first direction X =|L1-L2|.

The first reflective component 4302, the second reflective component 4303, and the third reflective component 4305 are combined to form a first optical path turning module.

The first reflective component 4302 has a first reflective surface 43021, the second reflective component 4303 has a second reflective surface 43031, and the first reflective surface 43021 and the second reflective surface 43031 are oppositely arranged in the first direction X. The first reflective surface 43021 forms an angle of 45 degrees with the first direction X, and the first reflective surface 43021 and the second reflective surface 43031 are perpendicular to each other, and they are arranged opposite to each other in the first direction X.

The fourth reflective surface 43052 is opposite to the second reflective surface 43031 in the third direction Z.

Preferably, the third reflective surface 42051 is parallel to the first reflective surface 43021, and the fourth reflective surface 43052 is parallel to the second reflective surface 43031. Those skilled in the art can understand that the fourth reflective surface 43052 is not necessary, the image sensor 4304 can be disposed opposite the second reflective component 4303, and the light reflected by the second reflective component 4303 can be directed directly without passing through the fourth reflective surface 43052.

Among them, L1 and L2 are absolute values.

Similarly, the first reflective component 4302 moves a distance L1 in the first direction X, and the second reflective component 4303 moves reversely a distance L2 in the first direction The optical path between the image sensors 4304 will be reduced by ΔS=L1+L2, thereby achieving automatic focusing of the lens device 4300.

Those skilled in the art can understand that when the values of L1 and L2 are equal, after the light is reflected by the second reflective component 4303, it will still proceed along the path that coincides with the path before moving. At this time, the light on the image sensor 4304 The imaging position will not change, and the lens device 4300 only implements autofocus. When the values of L1 and L2 are different, the light will deviate from the path before movement after being reflected by the second reflective component 4303.

In this way, the lens device 4300 not only achieves automatic focusing, but also achieves anti-vibration compensation.

The first reflective component 4302 moves a distance L1 in the first direction X, and the second reflective component 4303 moves a distance L2 in the first direction The deviation distance before movement is S=L1+L2, thus achieving anti-vibration compensation. Among them, L1 and L2 are absolute values.

The positive direction of Z; when the first reflective component 4302 and the second reflective component 4303 both move in the positive direction along the first direction X, the deviation direction of the imaging position of the light on the image sensor 4304 is the negative direction of the third direction Z. Towards.

Those skilled in the art can understand that when the values of L1 and L2 are equal, the imaging position of the light on the image sensor 4304 changes, and the deviation distance is S= L1+L2=2L1=2L2. At this time, the optical path between the first lens module 4301 and the image sensor 4304 remains unchanged. When the values of L1 and L2 are different, the imaging position of the light on the image sensor 4304 changes, and the deviation distance is S=L1+L2. At this time, the distance between the first lens module 4301 and the image sensor 4304 The optical path will also change, and the changing distance is △S=|L1-L2|.

Specifically, when the first reflective component 4302 and the second reflective component 4303 move forward by distances L1 and L2 respectively along the first direction X, when L1>L2, the optical path will increase, and the increased distance is Δ S=|L1-L2|; when L1<L2, the optical path will be reduced, and the reduced distance is △S=|L1-L2|. When the first reflective component 4302 and the second reflective component 4303 move in the negative direction by distances L1 and L2 respectively along the first direction |L1-L2|; When L1<L2, the optical path will increase, and the increased distance is △S=|L1-L2|.
