Referring to fig. 1, a periscopic camera module 100 according to a first embodiment of the present application includes a light steering device 10, a lens assembly 20, and a photosensitive assembly 30. The light diverter 10 reflects the incident light to the lens assembly 20 and the photosensitive assembly 30, and is received by the photosensitive assembly 30 for imaging.

The light redirecting element 10 includes a bottom surface 12 and three reflective surfaces 14 connected to the bottom surface 12. The lens assembly 20 includes three lens units 22, and each lens unit 22 is disposed corresponding to one of the reflective surfaces 14. The photosensitive assembly 30 includes three photosensitive members 32, and each photosensitive member 32 is disposed corresponding to one of the lens units 22. Wherein each lens unit 22 is held in the photosensitive path of the corresponding photosensitive member 32, and each reflecting surface 14 is held in the photosensitive path of the corresponding photosensitive member 32.

Thus, the incident light rays are reflected to the corresponding lens units 22 by the three reflecting surfaces 14, respectively, and the light rays passing through the corresponding lens units 22 are received by the photosensitive members 32 to realize imaging. Make this periscopic camera module group 100 possess the many structures of shooing of periscopic formula through light steering member 10 to reduced this periscopic camera module group 100's size, do benefit to periscopic camera module group 100's miniaturized design, single light steering member 10 can promote the stability of periscopic camera module group 100 simultaneously.

Further, the included angle between each reflective surface 14 and the bottom surface 12 is 45 °, so that the reflective surfaces 14 can reflect the incident light perpendicular to the bottom surface 12 to the corresponding lens unit 22 along the direction parallel to the bottom surface 12, thereby facilitating the assembly of the components of the periscopic camera module 100 and improving the assembly yield of the periscopic camera module 100.

It is understood that the included angle between the reflection surface 14 and the bottom surface 12 may be an acute angle such as 15 °, 30 °, 60 ° or 75 °, as long as the light reflected by the reflection surface 14 coincides with the optical axis of the lens unit 22.

Referring again to FIG. 1, the light redirecting element 10 is a triangular pyramid, with the base 12 and the reflecting surface 14 being triangular. Each lens unit 22 and the photosensitive member 32 are disposed corresponding to the side of the triangular pyramid.

Further, the light steering member 10 may also be a regular triangular pyramid, the reflective surface 14 is a side surface of the regular triangular pyramid, the bottom surface 12 is a regular triangle, the three reflective surfaces 14 are isosceles triangles with the same shape, and the three lens units 22 and the three light sensing members 32 are uniformly distributed on the periphery side of the light steering member 10.

The photosensitive element 32 is an imaging component of the periscopic camera module 100, and can convert light into pictures, i.e. form images after being sensed. In the present embodiment, the external light can be projected onto the photosensitive element 32 through the reflective surface 14, so as to form an image smoothly. Typically, the photosensitive member 32 may be a CMOS photosensitive chip.

Further, the periscopic camera module 100 further includes a first driving element 40, the light diverting element 10 is disposed on the first driving element 40, and the first driving element 40 is used for driving the light diverting element 10 to move so as to adjust the reflection angles of the three reflection surfaces 14, so that the optical axis of the light reflected by at least one reflection surface 14 coincides with the optical axis of the corresponding lens unit 22.

It can be understood that the periscopic camera module 100 has a dual-camera structure, for example, the light steering member 10 is adjusted by the first driving member 40 to maintain the two reflecting surfaces 14 in the photosensitive paths of the photosensitive members 32, so as to adjust the multi-camera mechanism by adjusting the light steering member 10 by the first driving member 40 to maintain the reflecting surfaces 14 in the photosensitive paths of the photosensitive members 32.

Further, when the number of the reflective surfaces 14 is greater than three, the number of the reflective surfaces 14 retained on the photosensitive path of the photosensitive member 32 can be adjusted according to the requirement when the first driving member 40 drives the light diverting member 10 to move by configuring the angle of the reflective surfaces 14 and the placement of the lens unit 22 and the photosensitive member 32.

Specifically, the first driving element 40 drives the light redirecting element 10 to move in the opposite direction according to the offset direction of the light redirecting element 10, so as to compensate the offset, and thus, the light redirecting element 10 can be prevented from shaking.

Further, referring to fig. 1 again, the periscopic camera module 100 further includes a sensing unit 60, the sensing unit 60 includes a first sensing element 62, a second sensing element 64, and a third sensing element 66, the first sensing element 62, the second sensing element 64, and the third sensing element 66 are respectively disposed adjacent to the three reflective surfaces 14, and the first sensing element 62, the second sensing element 64, and the third sensing element 66 are respectively used for sensing whether the corresponding reflective surface 14 is kept in the photosensitive path of the photosensitive element 32.

It is understood that the periscopic camera module 100 further includes a control member (not shown) electrically connected to the sensing unit 60 and the first driving member 40. If the first, second or third sensing elements 62, 64 or 66 sense that the corresponding reflective surface is no longer in the photosensitive path of the photosensitive element 32, the control element controls the first driving element 40 to drive the light diverting element 10 to move so as to adjust the reflective angle of the reflective surface 14.

In this embodiment, the first sensing element 62, the second sensing element 64 and the third sensing element 66 may be laser sensors, and the arrangement and position thereof may be designed and adjusted according to actual requirements.

For example, the second driving member 50 drives the lens unit 22 to move in a direction parallel to the optical axis or perpendicular to the optical axis, so as to prevent the lens unit 22 from shaking.

Referring to fig. 2, the lens unit 22 includes a first sub-lens unit 222 and a second sub-lens unit 224, and the first sub-lens unit 222 and the second sub-lens unit 224 are sequentially installed on the photosensitive paths of the corresponding photosensitive members 32, wherein the first sub-lens unit 222 is a fixed focus lens, the second sub-lens unit 224 is a zoom lens, the second sub-lens unit 224 is disposed on the second driving member 50, and the second driving member 50 is used for driving the second sub-lens unit 224 to move along the optical axis direction.

When the second driving member 50 is an actuator, the actuator can drive one or more lens groups in the first sub-lens unit 222 and the second sub-lens unit 224 simultaneously or time-divisionally. It can be seen that only one actuator is installed, which facilitates the disassembly, simplifies the internal structure of the periscopic camera module 100, and is beneficial to the lightness and thinness of the periscopic camera module 100.
