It should be understood that in the description of the embodiments of the present application, the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", etc. indicate orientations or positional relationships based on those shown in the drawings, and are only for convenience of describing the technical solutions of the embodiments and simplifying the description, but do not indicate or imply that the devices or elements must have specific orientations, be constructed in specific orientations, and be operated, and thus, should not be construed as limiting the present application.

Fig. 2 is a schematic partial structure diagram of a camera module according to an embodiment of the present application. Referring to fig. 2 to 4, the camera module 10 includes at least two cameras, and specifically, the camera module 10 may include two cameras, three cameras, four cameras, or more cameras. The cameras are classified according to their types, specifically into two categories, namely a first camera 11 and a second camera 12, and each category of cameras may include one or more cameras. The first camera 11 is a vertical camera of the type having only an incident optical axis a1 and no reflected optical axis b; the second camera 12 is a periscopic camera of the type having both an incident optical axis a2 and a reflected optical axis b.

In the two types of cameras, any one of the cameras may be one of a black-and-white camera, an RGB camera, an infrared camera, a wide-angle camera, a telephoto camera, and the like, which is not limited in the embodiment of the present application.

The first camera 11 and the second camera 12 each include a focusing lens group and a photosensitive element, specifically, the first camera 11 includes a first focusing lens group 111 and a first photosensitive element 112, the second camera 12 includes a second focusing lens group 121 and a second photosensitive element 122, and the difference is that the second camera 12 further includes a reflective element 123.

The first focusing lens group 111 and the second focusing lens group 121 respectively include one lens or a plurality of lenses, which are sequentially arranged along the respective focusing axes and perform focusing. The surface type of each lens can be any one of an aspheric surface, a spherical surface, a Fresnel surface and a binary optical surface. The lens can be made of glass, so that the cost is reduced and the mass production is facilitated.

The first photosensitive element 112 and the second photosensitive element 122 may each be a Complementary Metal-Oxide Semiconductor (CMOS) photosensitive element or a Charge-coupled Device (CCD) photosensitive element.

For the first camera 11, the incident light passes through the first focusing lens group 111 and then forms an image on the first photosensitive element 112, and for the second camera 12, the incident light is reflected by the reflecting element 123, then passes through the second focusing lens group 121 and then forms an image on the second photosensitive element 122. The incident light axes of the first camera 11 and the second camera 12 are parallel, and the incident light axes of the two cameras are perpendicular to the reflection light axis b of the second camera 12. The incident optical axis represents an optical axis of a light beam incident on the reflective element 123 or the first focusing lens group 111, and the reflection optical axis b represents an optical axis of a light beam reflected by the reflective element 123.

In the state where the camera is assembled, the first focus lens group 111 and the first photosensitive element 112 are sequentially located on the incident optical axis a1, and at this time, the optical axis of the first focus lens group 111 coincides with the center normal of the first photosensitive element 112; the reflecting element 123 is located on the incident optical axis a2, and the second focusing lens group 121 and the second photosensitive element 122 are sequentially located on the reflecting optical axis b of the second camera head 12, at this time, the optical axis of the light beam reflected by the reflecting element 123 coincides with the optical axis of the second focusing lens group 121 and the central normal of the second photosensitive element 122.

Taking the horizontal direction in fig. 2 as the first direction x and the vertical direction perpendicular to the first direction x as the second direction y as an example, as shown in fig. 3, when the camera module 10 is used for front-end shooting of the electronic device 20, the second camera 12 and the first camera 11 may be arranged along the first direction x, at this time, the incident optical axes of the two cameras are both in a direction perpendicular to the screen of the electronic device 20, and the reflection optical axis b of the second camera 12 is the first direction x.

When the camera module 10 is used for rear-end shooting of the electronic device 20, as shown in fig. 2 and 4, the first camera 11 and the second camera 12 may be arranged in a second direction y, and at this time, the incident optical axes of the two cameras are both in a direction perpendicular to the rear cover of the electronic device 20, and the reflection optical axis b of the second camera 12 is the second direction y.

The incident light passes through the first focusing lens group 111 along the incident optical axis a1 of the first camera 11 and forms an image on the first photosensitive element 112, thereby realizing shooting by the first camera 11. The incident light reaches and passes through the reflection element 123 along the incident light axis a2 of the second camera 12, is reflected by the reflection element 123, then passes through the second focusing lens group 121 along the reflection light axis b, and then forms an image on the second photosensitive element 122, thereby implementing shooting by the second camera 12. The first camera 11 and the second camera 12 may perform photographing individually or may cooperate to perform photographing simultaneously and finally be imaged by the electronic device 20.

As can be seen from the above description, the incident optical axis a1 of the first camera 11 is parallel to the incident optical axis a2 of the second camera 12, the incident optical axis a1 of the first camera 11 is perpendicular to the reflection optical axis b of the second camera, which is equivalent to the first camera 11 being compatible with the direction of the reflection optical axis b of the second camera 12, and the second camera 12 as a periscopic camera has a larger space in the first direction x (i.e. the direction of the reflection optical axis b), so that the first camera 11 can be laid out without increasing the space in the direction of the reflection optical axis b of the second camera 12, and the two cameras can share the module of the second camera 12, thereby enabling a plurality of cameras to share the module, reducing the space occupied by the plurality of cameras, and facilitating space optimization of the electronic device 20.

The first camera 11 may be disposed between the reflective element 123 and the second photosensitive element 122 of the second camera 12, and specifically, the first focus lens group 111 and the first photosensitive element 112 are both located between the reflective element 123 and the second photosensitive element 122 along the direction of the reflection optical axis b. In this way, the volume of the camera module 10 can still maintain the volume of the second camera 12 module, which is beneficial to cater for the miniaturized design of the electronic device 20.

The module described herein may be understood as a space for accommodating the camera, and this space may be reserved by the housing of the electronic device 20 itself, or may be a housing separately disposed outside the camera, such as a lens barrel that covers and protects the camera.

Referring to fig. 2, the camera module 10 further includes a lens barrel 13, a first focus lens group 111 and a first photosensitive element 112 of the first camera 11, and a second focus lens assembly 121, a second photosensitive element 122 and a reflective element 123 of the second camera 12, all disposed in an accommodating space defined by the lens barrel 13.

In an embodiment, as shown in fig. 2, the lens barrel 13 may have a three-dimensional structure with a rectangular cross section, that is, the lens barrel 13 has a rectangular parallelepiped structure. Specifically, the lens barrel 13 includes six rectangular walls that are classified into a bottom plate 131, four side walls 132, and a top plate 133 according to positions, wherein the bottom plate 131 and the top plate 133 are disposed at an interval, the four side walls 132 are sequentially connected end to end and connected between the bottom plate 131 and the top plate 133, and the four side walls 132 are respectively referred to as a front side wall, a rear side wall, a left side wall, and a right side wall according to the orientation shown in fig. 2.

The first photosensitive element 112 is disposed on the bottom plate 131, and the second photosensitive element 122 is disposed on the left sidewall 132. The positions of the other elements in the lens barrel 13 and the adopted fixing mode can be adaptively designed according to actual needs.

The top plate 133 of the lens barrel 13 is provided with a first light inlet window 1331 and a second light inlet window 1332, the first light inlet window 1331 corresponds to the first focusing lens group 111 of the first camera 11, and the second light inlet window 1332 corresponds to the reflecting element 123 of the second camera 12. Light rays (i.e., incident light) outside the lens barrel 13 enter the first focusing lens group 111 through the first light entrance window 1331, enter the reflection element 123 through the second light entrance window 1332, and form images on the respective photosensitive elements of the two cameras along the aforementioned optical paths (optical axes).

The types and materials of the first light inlet window 1331 and the second light inlet window 1332 should be adaptively selected according to the types of the respective cameras. For example, when the second camera 12 is an infrared camera, the second light inlet window 1332 may be a through hole, and the top plate 133 of the lens barrel 13 is made of a material opaque to infrared light. For another example, the top plate 133 is made of a material opaque to infrared light and a material transparent to infrared light, and specifically, the second light inlet window 1332 is made of a material transparent to infrared light, and the rest is made of a material opaque to infrared light.

In the embodiment of the present disclosure, the camera module 10 may further include a first optical filter 113 and a second optical filter 124, where the first optical filter 113 is located on the light incident side of the first photosensitive element 112, specifically between the first focusing lens set 111 and the first photosensitive element 112, and the second optical filter 124 is located on the light incident side of the second photosensitive element 122, specifically between the second focusing lens set 121 and the second photosensitive element 122. The two types of filters are used for selecting light with a preset wavelength meeting the imaging requirement and allowing the light to be transmitted to the corresponding photosensitive elements. For example, the second filter 124 may be an infrared filter for isolating visible light and allowing infrared light to enter the second photosensitive element 122. For another example, the first filter 113 may be an infrared cut filter, which is used to adjust a wavelength range of the imaging light, specifically, to isolate infrared light from entering the first photosensitive element 112, so as to prevent the infrared light from affecting the color and the definition of the normal image.

As shown in fig. 2, the first light inlet window 1331 may protrude from a plane where the second light inlet window 1332 is located, so as to adapt to a focusing size required by the vertical camera 11. At this time, the first focusing lens group 111 may be fixed to the top plate 133 of the lens barrel 13.

Of course, the first light inlet window 1331 and the second light inlet window 1332 may be flush (where "flush" means that the heights are on the same horizontal line), and the top plate 133 of the lens barrel 13 may be a flat plate. Thus, the two types of cameras have the same height, which is beneficial to reducing the overall height of the camera module 10, facilitating the electronic device 20 to be thinner and having a more beautiful appearance.

Referring to fig. 2, the reflective element 123 is disposed on the light incident side of the second focusing lens group 121, and may be a prism or a plane mirror. The prism and the plane mirror can be used for reflecting light rays to change the direction of a light path, have the advantages of compact structure and small volume, and are beneficial to the miniaturization of the camera module 10. Of course, the kind of the reflective element 123 is not limited thereto.

Taking the reflective element 123 as a prism for example, the reflective element 123 includes an incident surface 1231, an exit surface 1232, and a reflective surface 1233, wherein the incident surface 1231 is perpendicular to the exit surface 1232 and corresponds to the second light incident window 1332, and the reflective surface 1233 is connected to the incident surface 1231 and the exit surface 1232 and is used for reflecting the incident light entering through the second light incident window 1332.

In an embodiment, the side wall 132 of the lens barrel 13 may be formed with a notch (not shown), and each camera further includes a circuit board (not shown), and the circuit board is electrically connected to the photosensitive element and exposed from the notch. The Circuit Board may be any one of a Printed Circuit Board (PCB), a Flexible Printed Circuit Board (FPC), and a rigid-Flexible Board, one end of the Circuit Board may be located in the lens barrel 13 and electrically connected to the photosensitive element, and the other end of the Circuit Board may extend out of the notch and be connected to a main Circuit Board of the electronic device 20. The photosensitive element performs photoelectric conversion on incident light and outputs the converted light to the main circuit through the circuit board for imaging and other processing.

In the example shown in fig. 2, the left side wall 132 of the lens barrel 13 may be opened with a notch, and the first circuit board is disposed on the left side wall 132 and exposed from the notch of the left side wall 132 to be connected to the main circuit board of the electronic device 20. The bottom plate 131 of the lens barrel 13 may be opened with a notch, and the second circuit board is disposed on the bottom plate 131 and exposed from the notch of the bottom plate 131, and connected to the main circuit board of the electronic device 20. Of course, the circuit boards of these two types of cameras may also be disposed on the other adjacent side walls 132, and the notch may also be designed adaptively according to actual needs.

In the lens barrel 13, the positions and fixing manners of the components of the camera module 10 can be adaptively designed according to actual needs. For example, the second camera 12 further includes a support (not shown) that is abutted against the reflection element 123 and the bottom plate 131 and the right side wall 132 of the lens barrel 13, respectively. The support supports the reflective element 123 to maintain a predetermined tilt angle, for example, to make the reflective surface 1233 thereof form an angle of 45 ° with the bottom plate 131.

For another example, the reflective element 123 may be fixed by a curable adhesive to maintain a fixed state of a predetermined tilt angle, so that the tilt angle of the reflective element 123 may be adjusted by adjusting the thickness of the curable adhesive at different positions, and the adjustment method is simple.

For another example, the side wall 132 and the bottom plate 131 of the lens barrel 13 may be respectively provided with a groove, and both ends of the reflective element 123 (abutting against the side wall 132 and the bottom plate 131) are respectively clamped in the grooves, and the reflective surface 1233 of the reflective element 123 is kept at a predetermined inclination angle.
