It is understood that the types of the first auxiliary lens 11 and the second auxiliary lens 12 are not limited to the above listed lens types, and lenses with other functions may be selected, which are not exhaustive.
Specifically, the first photoreceptor 15 is fixedly disposed on the optical axis of the first auxiliary lens 11, and the first photoreceptor 15 is a photosensitive chip and includes a first photosensitive surface for receiving the light beam.
The set of reflecting means comprises first reflecting means 13 and second reflecting means 14. The first reflection device 13 is rotatably disposed between the first auxiliary lens 11 and the first photoreceptor 15, and the second reflection device 14 is fixedly disposed on the optical axis of the second auxiliary lens 12.
In this embodiment, the first reflecting device 13 includes a plane mirror 131 and a rotary driving member 132, the rotary driving member 132 is drivingly connected to the plane mirror 131, and a rotation axis of the plane mirror 131 is parallel to the first photoreceptor 15 and the second reflecting device 14; the rotary drive 132 may be a rotary motor.
The second reflecting device 14 is a total reflection prism, which can avoid light loss during reflection.
Further, the first reflecting device 13 has a first reflecting surface and a blocking surface which are respectively located on the front surface and the back surface of the plane mirror 131; the second reflecting device 14 has a second reflecting surface, and the second reflecting surface is positioned on the bottom surface of the total reflection prism; the first photoreceptor 15 has a first photosensitive surface.
Specifically, the optical axes of the first auxiliary lens 11 and the second auxiliary lens 12 are parallel, the optical axis of the first auxiliary lens 11 is perpendicular to the first light sensing surface, and the optical axis of the second auxiliary lens 12 and the second reflection surface form an included angle of 45 °.
The switching principle for the first auxiliary lens 11 and the second auxiliary lens 12 is as follows:
when the first auxiliary lens 11 is adopted, as shown in fig. 1, the first reflection device 13 is rotated to a first angle, and the first reflection device 13 is located at one side of the optical axis of the first auxiliary lens 11, and the first reflection surface is parallel to the optical axis of the second auxiliary lens 12. A direct path is formed between the first auxiliary lens 11 and the first photoreceptor 15, and the first auxiliary lens avoids the first light beam 31, and the first light beam 31 can directly enter the first photoreceptor 15 along the direct path to form an image; in this state, the second light beam 32 is reflected by the second reflecting device 14 and then enters the first reflecting surface at an angle of 90 ° and finally returns in the original path, so that the second light beam 32 cannot enter the first photoreceptor 15.
When it is required to switch to the second auxiliary lens 12, as shown in fig. 2, the first reflection device 13 is rotated to a second angle, and the first reflection device 13 intersects with the optical axis of the first auxiliary lens 11 to block the direct path, so that the first light beam 31 is directly incident on the blocking surface and cannot enter the first photoreceptor 15. At this time, the first reflective surface is parallel to the second reflective surface, and the second light beam 32 passes through the second reflective device 14 and then enters the first reflective surface at an angle of 45 °, and finally is reflected to the first photoreceptor 15 for imaging.
Referring to the orientation shown in fig. 1 and fig. 2, the first reflection device 13 rotates clockwise 45 ° from the first angle to the second angle.

The switching manner of the third auxiliary lens 16 is similar to that of the second auxiliary lens 12, and specifically includes the following steps:
when the first auxiliary lens 11 or the second auxiliary lens 12 is needed to be used, the first reflecting device 13 is rotated to the first angle or the second angle, and the third light beam 33 is reflected by the third reflecting device 17 to enter the shielding surface of the first reflecting device 13, so that the third light beam 33 cannot enter the first photoreceptor 15.
When it is required to switch to the third auxiliary lens 16, as shown in fig. 5, the first reflection device 13 is rotated to a third angle to block the direct path between the first auxiliary lens 11 and the first photoreceptor 15, so that the first light beam 31 cannot enter the first photoreceptor 15. The second light beam 32 is reflected by the second reflecting device 14 and the first reflecting device 13 to the outside of the first photoreceptor 15, and cannot enter the first photoreceptor 15. At this time, the third light beam 33 passes through the third reflection device 17 and then enters the first reflection surface at an angle of 45 °, and finally is reflected to the first photoreceptor 15 for imaging.
Referring to the orientation shown in fig. 3 and 4, the first reflecting device 13 is rotated clockwise by 90 ° from the second angle, i.e. rotated to the third angle.
In this embodiment, the third reflecting device 17 is a total reflection prism, and the third reflecting surface is located on the bottom surface of the total reflection prism.

The main camera module 20 comprises a main lens 21 and a second photoreceptor 22, the main lens 21 is used for collecting a fourth light beam 34, and the fourth light beam 34 enters the second photoreceptor 22 to form an image in the second photoreceptor 22.
