[0020] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0021] In the related art, electronic devices are usually equipped with multiple cameras, such as wide-angle cameras, telephoto cameras, panoramic cameras, etc. Although these cameras are assembled together as a whole, each camera is installed separately. This leads to an increase in the installation space required for the camera, which is easy to squeeze the installation space of other components of the electronic device and even cause interference with other components. At the same time, due to the lack of space, the camera cannot be designed to be larger, which also limits the image quality of the images collected by the electronic device.

[0022] Based on this, the inventor of the present application proposes a camera assembly 30 and an electronic device 10 in order to improve the above technical problems. The following is a detailed description in conjunction with specific embodiments and drawings:

[0023] Figure 1 as well as Figure 2 An electronic device 10 is shown, which includes a housing 20 and a camera assembly 30 , wherein the camera assembly 30 is disposed in the housing 20 , and the camera assembly 30 is used to collect image information.

[0024] Please also refer to and Figure 2 and Figure 3 The housing 20 includes a front housing 23, a middle frame 22, and a rear housing 21, wherein the front housing 23 and the rear housing 21 are respectively mounted on opposite sides of the middle frame 22, and the front housing 23 is used to mount a display screen, and the accommodation space formed between the rear housing 21 and the middle frame 22 can be used to install various components of the electronic device 10, such as a motherboard, a battery, etc. In this embodiment, a fixing hole 24 is provided on the rear housing 21, and the fixing hole 24 can pass through the rear housing 21. It should be noted that the fixing hole 24 can also be provided in the front housing 23. In this embodiment, the fixing holes can be provided in both the front housing 23 and the rear housing 21.

[0025] It is understandable that the front shell 23 and the rear shell 21 can be made of various materials such as metal, plastic, glass, ceramic, etc., and the front shell 23 and the rear shell 21 can be made of the same material or different materials, which is not limited here. The housing 20 has a first side and a second side opposite to each other, wherein the first side refers to the side of the front shell 23 of the housing 20, and the second side refers to the side of the housing 20 close to the rear shell 21.

[0026] See also Figure 4The camera assembly 30 includes a light incident assembly 31, a first image sensor 32 and a second image sensor 33. The first image sensor 32 and the second image sensor 33 are arranged at an interval. The light incident assembly 31 is used to receive incident light, wherein the incident light can enter the light incident assembly 31 from two opposite directions and be guided by the light incident assembly 31 into the first image sensor 32 and the second image sensor 33 respectively.

[0027] The first image sensor 32 includes but is not limited to a wide-angle image sensor, a telephoto image sensor, a macro image sensor, a panoramic image sensor, etc., and the second image sensor 33 includes but is not limited to a wide-angle image sensor, a telephoto image sensor, a macro image sensor, a panoramic image sensor, etc. The first image sensor 32 and the second image sensor 33 can be image sensors of the same type or different types, which is not specifically limited in this embodiment. In this embodiment, the first image sensor 32 is disposed on the front shell and can collect light from a fixed hole disposed on the front shell, serving as the front camera of the electronic device 10, and the second image sensor 33 is disposed on the rear shell and can collect light from a fixed hole disposed on the rear shell, serving as the rear camera of the electronic device 10.

[0028] Please continue reading Figure 4 The light incident component 31 includes a first reflector 311, and the first reflector 311 is used to receive the first light S1 and the second light S2, and reflect the first light S1 and the second light S2. The first light S1 and the second light S2 are incident on the first reflector 311 from two opposite directions. Specifically, the first light S1 is incident on the first reflector 311 from the first side of the housing 20, and the second light S2 is incident on the first reflector 311 from the second side of the housing.

[0029] In one embodiment, the first reflector 311 may have two reflective surfaces, and the first light S1 and the second light S2 are reflected on the two reflective surfaces respectively. Figure 5 The first reflector 311 is a right-angle prism 3111, and the right-angle prism 3111 has a reflective surface 3112. The reflective surface 3112 can be, for example, the inclined surface of the right-angle prism 3113. The angle between the reflective surface 3112 and the first light S1 and the second light S2 is approximately 45°. The reflective surface 3112 is formed with a reflective film 3113. The first light S1 and the second light S2 are incident on the reflective film 3113 from opposite sides of the reflective film 3113 and are reflected in opposite directions by the reflective film 3113. After being reflected by the first reflector 311, the first light S1 and the second light S2 propagate in opposite directions.

[0030] More specifically, the first light S1 and the second light S2 are both incident along the Y direction, and the Y direction may be the thickness direction of the electronic device 10. Of course, in some other embodiments, the Y direction may also be the length direction or the width direction of the electronic device 10 according to the difference in the setting position of the electronic device 10. The reflected first light S1 and the second light S2 propagate along the X direction, wherein the X direction and the Y direction may be substantially perpendicular to each other, and the X direction may be the length direction or the width direction of the electronic device 10, or other directions, which is not limited in this embodiment.

[0031] Due to the separation effect of the reflective film 3113, the first light S1 and the second light S2 incident from opposite sides will not mix. The first image sensor 32 is arranged on the optical path of the first light S1 after being reflected, and the first light S1 after being reflected enters the first image sensor 32 along the subsequent optical path. The second image sensor 33 is arranged on the optical path of the second light S2 after being reflected, and the second light S2 after being reflected enters the second image sensor 33 along the subsequent optical path.

[0032] In this embodiment, the first image sensor 32 is arranged corresponding to the first reflector 311 in the X direction, and the second image sensor 33 is arranged corresponding to the first reflector 311 in the X direction. In this way, the entire camera assembly 30 can save space in the Y direction. The light incident assembly 31 can also include a light incident lens 312, which can be arranged on the optical path of the first light S1 incident on the first reflector 311, and / or, on the optical path of the second light S2 incident on the first reflector 311, which is not limited in this embodiment. Figure 4 In the illustrated embodiment, only as an example, there is one light incident lens 312 , which is disposed on the optical path of the second light S2 incident on the first reflector 311 .

[0033] In this embodiment, please continue to refer to Figure 4 The camera assembly 30 also includes a first light guiding device 34 and a second light guiding device 35. The first light guiding device 34 is arranged between the first reflector 311 and the first image sensor 32 and is located on the light path of the first light beam S1. The first light guiding device 34 is used to guide the first light beam S1 into the first image sensor 32.

[0034] In this embodiment, the first light guiding device 34 may include an aperture L1, a first lens L2, and a second lens L3. The aperture L1, the first lens L2, and the second lens L3 are sequentially arranged between the first image sensor 32 and the first reflector 311, and the optical axes of the aperture L1, the first lens L2, and the second lens L3 coincide. After the first light S1 is reflected by the first reflector 311, it sequentially passes through the aperture L1, the first lens L2, and the second lens L3 to enter the first image sensor 32. The aperture L1 can be used to adjust the luminous flux of the first light S1 entering the first image sensor 32. The first lens L2 and the second lens L3 can shape and homogenize the first light S1, and adjust the light spot of the first light S1 when entering the first image sensor 32.

[0035] The second light guiding device 35 is disposed between the first reflective member 311 and the second image sensor 33 and is located on the optical path of the second light beam S2 . The second light guiding device 35 is used for guiding the second light beam S2 into the second image sensor 33 .

[0036] In this embodiment, the second light guiding device 35 includes an aperture L4, a third lens L5, a fourth lens L6 and a fifth lens L7, and the aperture L4, the third lens L5, the fourth lens L6 and the fifth lens L7 are arranged in sequence along the propagation direction of the second light ray S2, wherein the aperture L4 can be used to adjust the light flux entering the second image sensor 33, and the third lens L5, the fourth lens L6 and the fifth lens L7 can shape and homogenize the second light ray S2, and adjust the light spot when the second light ray S2 enters the second image sensor 33.

[0037] Since the incident light (i.e., the first light S1 and the second light S2) are both natural light, which contains infrared light, and when the infrared light enters the image sensor, it may cause the image to be reddish, in order to improve the image quality, the infrared light part of the first light S1 and the second light S2 can be filtered out. For example, an infrared filter can be set in the optical path of the first light S1 and the optical path of the second light S2, and an infrared filter can also be set in the optical path of the incident light in the light input component 31 to filter out the infrared light.

[0038] In one embodiment, the camera assembly 30 may further include an infrared light cutoff film (not shown), which may be disposed on the surface of the incident lens 312 and located on the image side of the incident lens 312. When the incident light enters the incident lens 312, the infrared light in the incident light is filtered out by the infrared light cutoff film, thereby preventing the infrared light from entering the first image sensor 32 and the second image sensor 33 in the subsequent optical path. By disposing the infrared light cutoff film on the image side surface of the incident lens 312, the use of the infrared filter can be reduced, thereby reducing the size of the entire camera assembly 30, and further reducing the volume of the camera assembly 30.

[0039] In some other embodiments, the infrared light cut-off film may also be disposed in the first light guide device 34 and the second light guide device 35, which is not limited in this embodiment. In some other embodiments, the first image sensor 32 and the second image sensor 33 are both provided with an infrared light cut-off film, that is, the infrared light cut-off film is disposed on the microlens of the first image sensor 32 and the second image sensor 33, for example, formed on the microlens of the first image sensor 32 and the second image sensor 33 by plating. In this embodiment, the infrared cut-off film is disposed on the image side surface of the incident lens 312 and the object side surface of the aperture L1.

[0040] By providing an infrared light cutoff film, infrared light in the light entering the first image sensor 32 and the second image sensor 33 can be filtered out, thereby improving the image quality of the imaging, while avoiding the problem of increased volume caused by providing an infrared filter.

[0041] In this embodiment, the first image sensor 32 can be used as a front camera of the electronic device 10 , and the second image sensor 33 can be used as a rear camera of the electronic device 10 .

[0042] It should be noted that the “image side” in the present application refers to the side of the element close to the image sensor, and the “object side” refers to the side of the element close to the light source.

[0043] In the camera assembly 30 provided in the above embodiment, the first image sensor 32 and the second image sensor 33 both receive light through the light incident assembly 31. The first reflector 311 of the light incident assembly 31 can reflect the first light S1 and the second light S2 incident from opposite sides into the first image sensor 32 and the second image sensor 33 for imaging. Since the first image sensor 32 and the second image sensor 33 share a set of light incident assemblies 31, the number of components of the camera assembly 30 can be reduced, thereby reducing the volume of the camera assembly 30. The electronic device 10 using the camera assembly 30 does not need to reserve a large space, which is convenient for the layout of other components in the electronic device 10.

[0044] In another embodiment, the number of image sensors may be more than two, and in this case, the light incident component 31 may also be shared.

[0045] Specifically, see Figure 6, the camera assembly 30 also includes a third image sensor 36, and the light incident assembly 31 also includes a beam splitter 313. The beam splitter 313 is arranged on the optical path of the second light S2 after being reflected by the first reflector 311. The beam splitter 313 is used to separate the second light S2 to form a third light S3 and a fourth light S4; the separated third light S3 and the fourth light S4 propagate along different optical paths. The separated third light S3 enters the second image sensor 33 along the subsequent optical path, and the second image sensor 33 is used to receive the third light S3 and perform imaging. The separated fourth light S4 enters the third image sensor 36 along the subsequent optical path, and the third image sensor 36 is used to receive the fourth light S4 and perform imaging. In a more specific embodiment, the optical axis of the third light S3 and the optical axis of the fourth light S4 separated by the beam splitter 313 are perpendicular to each other.

[0046] In one embodiment, the spectrometer 313 may adopt a wavelength spectrometry method, that is, the spectrometer 313 separates the second light S2 into a third light S3 and a fourth light S4 with different wavelengths. It should be noted that the wavelength of the third light S3 and the wavelength of the fourth light S4 are both within a range of values. For example, the third light S3 may be blue light, and the fourth light S4 may be other visible light except blue light, or the fourth light S4 may be blue light, and the third light S3 may be other visible light except blue light. In this embodiment, the spectrometer 313 may reflect the fourth light S4 in the second light S2, and transmit the third light S3 in the second light S2, so as to separate the third light S3 and the fourth light S4, and the third light S3 that transmits the spectrometer 313 continues to propagate along the Y direction, and the fourth light S4 reflected by the spectrometer 313 propagates along the X direction.

[0047] In some other embodiments, the beam splitter 313 may reflect the third light ray S3 in the second light ray S2 and transmit the fourth light ray S4 in the second light ray S2, so as to separate the third light ray S3 from the fourth light ray S4.

[0048] Specifically, in this embodiment, refer to Figure 7 The light splitter 313 includes a prism 3131 and a semi-transparent and semi-reflective film 3133. The prism 3131 may be a right-angle prism 3131. The prism 3131 has a transflective surface 3132. The transflective surface 3132 may be an inclined surface of the prism 3131. The semi-transparent and semi-reflective film 3133 is disposed on the transflective surface 3132. The semi-transparent and semi-reflective film 3133 may transmit light of a specific wavelength and reflect light of other wavelengths, thereby realizing the separation of the third light S3 and the fourth light S4. The angle between the transflective surface 3132 and the optical axis direction X of the second light S2 may be 45°.

[0049] In this embodiment, the beam splitter 313 is arranged side by side with the first reflector 311 along the X direction to save the volume in the X direction. The second image sensor 33 is arranged corresponding to the beam splitter 313 and the first reflector 311 in the X direction, that is, the optical axis of the second image sensor 33 coincides with the optical axis direction of the second light S2 reflected by the first reflector 311. The advantage of such arrangement is that the third light S3 emitted from the beam splitter 313 can directly enter the second image sensor 33 without setting other components for deflection. The third image sensor 36 is arranged corresponding to the beam splitter 313 in the X direction, and the propagation direction of the fourth light S4 entering the third image sensor 36 is opposite to the propagation direction of the second light S2 entering the first reflector 311. The light-incoming lens 312 and the third image sensor 36 are located on the same side of the beam splitter 313. The camera assembly 30 also includes a third light guiding device 38, which is arranged between the beam splitter 313 and the third image sensor 36 and is used to guide the fourth light S4 to enter the third image sensor 36.

[0050] In this embodiment, the third light guiding device 38 includes a sixth lens L8 and a seventh lens L9, which are sequentially arranged between the beam splitter 313 and the third image sensor 36. The sixth lens L8 and the seventh lens L9 can shape and homogenize the fourth light S4 and adjust the light spot of the fourth light S4 when it enters the third image sensor 36.

[0051] Since the third image sensor 36 is disposed on one side of the beam splitter 313 and on the same side as the light incident lens 312, the third light guiding device 38 can be disposed side by side with the light incident lens 312, so the third image sensor 36 occupies less space in the Y direction (i.e., space in the thickness direction) of the electronic device 10, and the volume of the camera assembly 30 in the Y direction can be reduced. In some other embodiments, the third image sensor 36 can also be disposed on opposite sides of the beam splitter 313 with the light incident lens 312, which is not specifically limited in this embodiment.

[0052] It should also be noted that, in the present embodiment, the first image sensor 32 can be used as a front camera of the electronic device 10 , and the second image sensor 33 and the third image sensor 36 can be used as rear cameras of the electronic device 10 .

[0053] In another embodiment, see Figure 8 The light splitter 313 may also be a dichroic plate 3134. The dichroic plate 3134 may also transmit light of a specific wavelength and reflect light of other wavelengths. When the dichroic plate 3134 is set, it may also maintain a 45° angle with the optical axis direction Y of the second light S2. The setting method of other components may refer to the setting method of the prism mentioned above, and will not be repeated here.

[0054] In another embodiment, the beam splitter 313 may also adopt polarization beam splitting, that is, the beam splitter 313 separates the second light S2 into a third light S3 and a fourth light S4 with different polarization states, for example, the third light S3 may be S polarized light, and the fourth light S4 may be P polarized light, or the fourth light S4 may be S polarized light, and the third light S3 may be P polarized light. The beam splitter 313 may reflect the fourth light S4 in the second light S2, and transmit the third light S3 in the second light S2, so as to separate the third light S3 from the fourth light S4, the third light S3 that transmits the beam splitter 313 continues to propagate along the Y direction, and the fourth light S4 that is reflected by the beam splitter 313 propagates along the X direction, wherein the X direction and the Y direction may be substantially perpendicular to each other, and the X direction may be the length direction or the width direction of the electronic device 10, or other directions, which are not limited in this embodiment.

[0055] In some other embodiments, the beam splitter 313 may reflect the third light ray S3 in the second light ray S2 and transmit the fourth light ray S4 in the second light ray S2, so as to separate the third light ray S3 from the fourth light ray S4.

[0056] Specifically, see Fig. 9 The beam splitter 313 can be a polarization beam splitter prism 3135. The polarization beam splitter prism 3135 is achieved by coating a multilayer film structure on the inclined surface of a right-angle prism and then gluing them into a cubic structure. The transmittance of P-polarized light is 1 and the transmittance of S-polarized light is less than 1 when the light is incident at the Brewster angle. After the light passes through the multilayer film structure at the Brewster angle for multiple times, the P-polarized component is completely transmitted while most of the S-polarized component is reflected (at least 90%). This allows the separation of P-polarized light and S-polarized light to be achieved.

[0057] Similarly, in this embodiment, an infrared light cutoff film may be provided in the incident lens 312 and the first light guide device 34 to filter out the infrared light portion of the first light S1 and the second light S2. The specific configuration method may refer to the contents of the above embodiments and will not be described in detail here.

[0058] In another embodiment, see Fig.10The camera assembly 30 may also include a second reflector 37. The second reflector 37 is disposed on the optical path of the third light S3 and is used to reflect the third light S3. The second image sensor 33 receives the third light S3 that passes through the second reflector 37 and forms an image. After being reflected by the second reflector 37, the propagation direction of the third light S3 changes. Therefore, the setting position of the second image sensor 33 can be adjusted accordingly. Specifically in this embodiment, the third light S3 reflected by the second reflector 37 propagates along the Y direction and is opposite to the propagation direction of the second light S2 entering the light incident lens 312. The second image sensor 33 is disposed on one side of the second reflector 37 and is disposed corresponding to the second reflector 37 in the Y direction. The second image sensor 33 and the light incident lens 312 can be located on opposite sides of the second reflector 37. Compared with this arrangement, Figure 6 The illustrated embodiment can more reasonably utilize the space in the Y direction, thereby saving the size of the entire camera assembly 30 in the X direction, and further reducing the volume of the camera assembly 30.

[0059] The second reflector 37 may be a reflective element such as a reflective sheet, a reflective prism, etc. It should be noted that the reflection angle of the second reflector 37 when reflecting the third light S3 can be set as required, and this embodiment does not limit this.

[0060] In another embodiment, see Fig.11 The camera assembly 30 may further include a second reflector 37, which is disposed on the optical path of the third light S3 and is used to reflect the third light S3. The second image sensor 33 receives the third light S3 passing through the second reflector 37 and forms an image. After being reflected by the second reflector 37, the propagation direction of the third light S3 changes, so the setting position of the second image sensor 33 can be adjusted accordingly. Specifically in this embodiment, the third light S3 reflected by the second reflector 37 propagates along the Y direction, and is opposite to the propagation direction of the second light S2 entering the light-entering lens 312. The second image sensor 33 is disposed on one side of the second reflector 37, and is disposed correspondingly to the second reflector 37 in the Y direction (i.e., the direction in which the second light S2 is incident on the first reflector 311). The second image sensor 33 and the light-entering lens 312 are located on the same side of the second reflector 37. This arrangement can more reasonably utilize the space in the Y direction, thereby saving the size of the entire camera assembly 30 in the X direction, and further reducing the volume of the camera assembly 30. Furthermore, since the second image sensor 33 and the first image sensor 32 are located at approximately the same level position, disposing the second image sensor 33 on the side of the second reflector 37 away from the light incident lens 312 will not increase the size of the camera assembly 30 in the Y direction.

[0061] In the above-mentioned camera assembly 30, the first image sensor 32 and the second image sensor 33 are both incident through the light incident assembly 31. The first reflector 311 of the light incident assembly 31 can reflect the first light S1 and the second light S2 incident from opposite sides into the first image sensor 32 and the second image sensor 33 for imaging. Since the first image sensor 32 and the second image sensor 33 share a set of light incident assemblies 31, the number of components of the camera assembly 30 can be reduced, thereby reducing the volume of the camera assembly 30. The electronic device 10 using the camera assembly 30 does not need to reserve a large space, which is convenient for the layout of other components in the electronic device 10.

[0062] It should be noted that in some other embodiments, the number of image sensors may be more than three, and a similar arrangement may be adopted to reduce the volume of the camera assembly 30. For example, every two image sensors are arranged in the form of the aforementioned embodiment. Another example: by increasing the number of light splitting elements 313, the first light S1 is split again to achieve the purpose of multiple image sensors sharing the light incident assembly 31. In this embodiment, the number of image sensors is not limited.

[0063] The camera assembly 30 may also include a camera fixing part (not shown) and a decorative part (not shown), wherein the camera fixing part may be set to a roughly plate-like structure and is suitable for being set at the fixing hole 24 of the housing 20. When the camera fixing part is set at the fixing hole 24, the fixing hole 24 may be closed.
