[0037] The housing 5 can be a cylindrical housing or a prismatic housing. An opening is provided at the bottom of the housing 5, i.e., one end of the housing 5 along its own axis, and the circuit board 8 is located at the center of the opening. The side of the circuit board 8 facing the outside of the housing 5 is flush with the opening side of the housing 5. The first lens group 21 and the second lens group 22 are respectively located on the left and right sides of the circuit board 8, the first optical conversion element 11 is located above the first lens group 21, and the second optical conversion element 12 is located above the second lens group 22, that is, the first lens group 21 is corresponding to the first optical conversion element 11, and the second lens group 22 is corresponding to the second optical conversion element 12.

[0038] The circuit board 8 is fixed in the housing 5, and the bracket 10 is fixed on the surface of the circuit board 8 facing the inside of the housing 5. The first lens group 21 is fixed between the left wall of the bracket 10 and the inner wall of the housing 5, and the second lens group 22 is fixed between the right wall of the bracket 10 and the inner wall of the housing 5.

[0039] The photosensitive chip 3 is located in the space enclosed by the bracket 10 and the circuit board 8. The photosensitive chip 3 is electrically connected to the circuit board 8. The positions of the first lens group 21 and the second lens group 22 are symmetrical about the photosensitive chip 3. The bracket 10 is directly above the photosensitive chip 3, and a hole 101 is set on the bracket 10. The hole 101 allows light to pass through and hit the photosensitive chip 3. A groove 102 is set on the surface of the bracket 10 facing the refracting prism 4. The groove 102 is connected with the hole 101. A fixed filter 7 is embedded in the groove 102. The filter 7 is parallel to the upper surface of the photosensitive chip 3, and the filter 7 is located directly above the photosensitive chip 3. The light emitted from the refracting prism 4 is filtered by the light of the filter 7 and then emitted to the photosensitive chip 3. The light signal is converted into an electrical signal on the photosensitive chip 3 to generate an image.

[0040] The first optical conversion element 11 and the second optical conversion element 12 can both rotate; the purpose of the rotation of the first optical conversion element 11 is to adjust the angle formed by the mirror surface of the light emitted by the first optical conversion element 11 and the axis of the first lens group 21, so as to adjust the incident angle of the light on the surface of the refracting prism 4, so that the light emitted from the refracting prism 4 can be projected on the surface of the photosensitive chip 3, rather than on the circuit board 8 outside the photosensitive chip 3; similarly, the purpose of the rotation of the second optical conversion element 12 is to adjust the angle formed by the mirror surface of the light emitted by the second optical conversion element 12 and the axis of the second lens group 22, so as to adjust the incident angle of the light on the surface of the refracting prism 4, so that the light emitted from the refracting prism 4 can be projected on the surface of the photosensitive chip 3, rather than on the circuit board 8 outside the photosensitive chip 3. The first optical conversion element 11 and the second optical conversion element 12 can both be refractors or reflectors. In this embodiment, reflectors are preferably used as the first optical conversion element 11 and the second optical conversion element 12.

[0041] The camera module drives the first light transfer element 11 and the second light transfer element 12 to rotate respectively through two first drivers 61. In this embodiment, the motor is preferably the first driver 61; the first driver 61 can be fixed inside or outside the housing 5, and each first driver 61 drives a first rotating shaft 62. The first light transfer element 11 and the second light transfer element 12 are respectively fixed to the corresponding ends of the first rotating shaft 62, and the mirror surface of the light emitted by the first light transfer element 11 and the mirror surface of the light emitted by the second light transfer element 12 are parallel to the axis of the corresponding first rotating shaft 62.

[0042] The refractive prism 4 is a right triangular prism, and the three side surfaces of the refractive prism 4 are respectively a first refractive mirror surface 41, a second refractive mirror surface 42 and a reflective mirror surface 43, wherein the edge between the first refractive mirror surface 41 and the second refractive mirror surface 42 is set as a curved surface 44, the bisector of the curved surface 44 is perpendicular to the reflective mirror surface 43, and the first refractive mirror surface 41 and the second refractive mirror surface 42 are symmetrical about the bisector of the curved surface 44. The curved surface 44 is a transition surface between the first refractive mirror surface 41 and the second refractive mirror surface 42, and the curved surface 44 is tangent to the connection between the first refractive mirror surface 41 and the connection between the curved surface 44 and the second refractive mirror surface 42. The first refractive mirror surface 41, the second refractive mirror surface 42 and the curved surface 44 are light-transmitting mirror surfaces, and the reflective mirror surface 43 is an opaque mirror surface.

[0043] The refractive prism 4 can also rotate, and one of the purposes of the rotation is to adjust the angle of incidence of the light when it is emitted from the inside of the refractive prism 4 to the outside on the first refractive mirror surface 41 or the second refractive mirror surface 42, thereby adjusting the position where the light is incident on the photosensitive chip 3. The refractive prism 4 can be rotated alone to adjust the position where the light is incident on the photosensitive chip 3, or it can be rotated together with the first light conversion element 11 and / or the second light conversion element 12 to adjust the position where the light is incident on the photosensitive chip 3.

[0044] The camera module drives the refracting prism 4 to rotate through the second driver 91. In this embodiment, the preferred motor is the second driver 91; the second driver 91 can be fixed inside or outside the housing 5, the second driver 91 drives the second rotating shaft 92, the refracting prism 4 is fixed to the end of the second rotating shaft 92, the first refracting mirror surface 41, the second refracting mirror surface 42 and the reflecting mirror surface 43 are all parallel to the axis of the second rotating shaft 92, and the axis of the second rotating shaft 92 is also parallel to the axis of the first rotating shaft 62.

[0045] During the operation of the camera module, the refracting prism 4 can rotate at any time, that is, when the light emitted by the refracting prism 4 is imaged on the photosensitive chip 3, the second driver 91 still continues to drive the refracting prism 4 to rotate, thereby adjusting the direction of the light, indirectly playing an anti-shake function, and realizing a micro-pan-tilt working mode. When the camera module turns on the anti-shake function and the refracting prism 4 is in continuous rotation, the first optical conversion element 11 and / or the second optical conversion element 12 can also rotate continuously under the drive of the first driver 61, thereby cooperating with the rotation of the refracting prism 4, so that the refracting prism 4 can achieve a good anti-shake effect by rotating a small amplitude.

[0046] The rotation of the first light transfer element 11 and the second light transfer element 12 can not only coordinate with the anti-shake when the refractive prism 4 rotates, but also enable a wider range of subject reflected light to be reflected by the first light transfer element 11 or the second light transfer element 12 toward the refractive prism 4, and then refracted to the photosensitive chip 3 through the rotation of the refractive prism 4, thereby achieving the purpose of expanding the shooting angle range.

[0047] The camera module proposed in this embodiment has the following three working states: First working state: please refer to Figure 1 , external light enters only from the first lens group 21, the second lens group 22 is shielded and no external light enters, the refractive prism 4 is rotated so that the first refractive mirror surface 41 faces the first light conversion element 11 and the second refractive mirror surface 42 faces the photosensitive chip 3, and the light incident on the first light conversion element 11 through the first lens group 21 is reflected by the first light conversion element 11 and reaches the first refractive mirror surface 41, enters the refractive prism 4 from the first refractive mirror surface 41 and is reflected by the reflective mirror surface 43 and then emitted from the second refractive mirror surface 42 to the photosensitive chip 3, thereby converting the optical signal into an electrical signal to perform an image generation operation.

[0048] Second working status: please refer to Figure 2 , external light only enters from the second lens group 22, the first lens group 21 is shielded and no external light enters, the refractive prism 4 is rotated until the second refractive mirror surface 42 faces the second light conversion element 12 and the first refractive mirror surface 41 faces the photosensitive chip 3, the light incident on the second light conversion element 12 through the second lens group 22 is reflected by the second light conversion element 12 and reaches the second refractive mirror surface 42, the second refractive mirror surface 42 is incident on the refractive prism 4 and is reflected by the reflective mirror surface 43 and then emitted from the first refractive mirror surface 41 to the photosensitive chip 3.

[0049] The third working state: please refer to Figure 3 , external light enters from the first lens group 21 and the second lens group 22 without light shielding, the refractive prism 4 rotates until the first refractive mirror surface 41 faces the first light conversion element 11 and the photosensitive chip 3 and the second refractive mirror surface 42 faces the second light conversion element 12 and the photosensitive chip 3, the light incident on the first light conversion element 11 through the first lens group 21 is reflected by the first light conversion element 11 and reaches the first refractive mirror surface 41, enters the refractive prism 4 from the first refractive mirror surface 41 and is emitted from the second refractive mirror surface 42 to the photosensitive chip 3, at the same time, the light incident on the second light conversion element 12 through the second lens group 22 is reflected by the second light conversion element 12 and reaches the second refractive mirror surface 42, enters the refractive prism 4 from the second refractive mirror surface 42 and is emitted from the first refractive mirror surface 41 to the photosensitive chip 3, the light entering from the first lens group 21 and the second lens group 22 falls on the photosensitive chip 3 at the same time, and the image generation operation is performed.

[0050] Please refer to Figure 1In the first working state, the second refractive mirror surface 42 is parallel to the upper surface of the photosensitive chip 3, the first refractive mirror surface 41 is perpendicular to the upper surface of the photosensitive chip 3, and the reflective mirror surface 43 is inclined relative to the upper surface of the photosensitive chip 3;

[0051] Please refer to Figure 2 In the second working state, the first refractive mirror surface 41 is parallel to the upper surface of the photosensitive chip 3, the second refractive mirror surface 42 is perpendicular to the upper surface of the photosensitive chip 3, and the reflective mirror surface 43 is inclined relative to the upper surface of the photosensitive chip 3;

[0052] Please refer to Figure 3 In the third working state, the first refractive mirror surface 41 and the second refractive mirror surface 42 are both inclined relative to the upper surface of the photosensitive chip 3, and the reflective mirror surface 43 is parallel to the upper surface of the photosensitive chip 3.

[0053] In the first working state and the second working state, the first lens group 21 and the second lens group 22 can work independently to capture different angles; in the third working state, the first lens group 21 and the second lens group 22 can work simultaneously to increase the shooting angle range.

[0054] Please refer to Figure 3 In the third working state, the second driver 91 drives the refracting prism 4 to rotate until the reflecting mirror surface 43 is parallel to the upper surface of the photosensitive chip 3 and the arc surface 44 is in a state facing the upper surface of the photosensitive chip 3; the arc setting of the arc surface 44 can change the direction of the light, and the arc surface 44 is similar to the convex surface of a convex lens, which has the effect of gathering and converging the refracted light; in the third working state, if the light is emitted on the arc surface 44, it will be more offset toward the center of the photosensitive chip 3 than when it is emitted on the first refracting mirror surface 41 and the second refracting mirror surface 42, thereby avoiding the imaging range falling outside the photosensitive chip 3.

[0055] When the camera module of this embodiment is shooting, when the above three working states are switched, the first light transfer element 11, the second light transfer element 12 and the refractive prism 4 need to be rotated to the specified state in advance to form the image required for the specified working state on the photosensitive chip 3; and when the first light transfer element 11, the second light transfer element 12 and the refractive prism 4 are already in the specified working state, and the image corresponding to the working state is already on the photosensitive chip 3, if the anti-shake function is turned on, at least one component of the first light transfer element 11, the second light transfer element 12 and the refractive prism 4 will continue to rotate, thereby changing the angle of the light emitted by the refractive prism 4 to the photosensitive chip 3, thereby achieving the anti-shake effect.

[0056] The above description is only a specific implementation mode of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by a technician familiar with the technical field within the technical scope disclosed by the present invention should be covered within the protection scope of the present invention.
