As shown in the figure, a camera lens device capable of bidirectional shooting includes a camera lens 1 for imaging and a rotatable polygonal reflective prism 2 disposed on the side of the camera lens 1 facing the object side. External light 4 enters the imaging lens 1 after passing through the multi-faceted reflective prism 2 for imaging. The multi-faceted reflective prism 2 includes a first plane 21 and a second plane 22 for the light to enter or exit. The plane 22 and the adjacent second reflective surface 24 . The light 4 enters from the first plane or the second plane, is reflected by the first reflective surface and the second reflective surface, and then exits from the second plane or the first plane. The purpose of shooting in two directions can be achieved.

Further, the rotation center of the rotatable polygonal reflective prism 2 is located on the intersection line between the optical axis of the camera lens 1 and the bisectors of the first reflective surface 23 and the second reflective surface 24, which can effectively ensure that the camera lens 1 Receive the light beam to ensure the shooting effect, as shown in Figures 1 and 2.

The camera lens 1 and the multi-faceted reflective prism 2 together form a complete optical system, and the range of the optical field angle of the camera lens can reach 60-80 degrees. The optical system is installed in the housing 5 .

As a preferred mode of this embodiment, the rotation angle of the polygonal reflective prism 2 around its rotation center is 90 degrees or the polygonal reflective prism 2 rotates 180 degrees around the optical axis of the camera lens 1 . Before the rotation, light 4 enters from the first plane 21 of the prism, is reflected twice by the second reflective surface 24 and the first reflective surface 23 , and exits from the second plane 22 into the camera lens 1 to realize imaging. After rotating 90 degrees counterclockwise, the light 4 enters from the second plane 22 of the prism, is reflected twice by the first reflection surface 23 and the second reflection surface 24, and then exits the first plane 21 into the camera lens 1, thereby realizing imaging. Fig. 1 is the state diagram before the prism is not rotated, and Fig. 2 is the state diagram when the prism rotates 90 degrees around its rotation center or the multi-faceted reflective prism rotates 180 degrees around the optical axis of the camera lens.

Further, the phone case 3 includes a front 31 and a back 32 , the second plane 22 faces the front 31 of the phone case 3 , and the first plane 21 faces the back 32 of the phone case 3 .

When the prism in the camera lens device capable of bidirectional shooting was in the initial position, as shown in Figure 1, at this moment, the incident light 4 on one side of the back side of the mobile phone 32 was incident from the first plane 21 of the multi-faceted reflective prism 2, through the second reflection Surface 24 and the first reflective surface 23 reflect continuously and then shoot out from the second plane 22 into the camera lens 1 to complete the shooting on the back side of the mobile phone 32 . When it is necessary to take pictures of the front side of the mobile phone 31, the multi-faceted reflective prism 2 is controlled to rotate 90 degrees counterclockwise through the control device in the camera lens device capable of bidirectional shooting. The position of the multi-faceted reflective prism 2 is limited. At this time, the incident light 4 on the front side of the mobile phone 31 is incident from the second plane 22 of the multi-faceted reflective prism 2, and after continuous reflection from the first reflective surface 23 and the second reflective surface 24, it is reflected from the second reflective prism.
