[0002] In the prior art, electronic devices such as smart phones are usually equipped with cameras, and in order to meet different photography needs, the number of cameras has gradually increased, which leads to an increase in the installation space required for the cameras, 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. Summary of the invention

[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 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 at least partially exposed, and the camera assembly 30 is used to collect image information.

[0024] Please also refer to and Figure 1 and Figure 2 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, a camera 50, etc. In this embodiment, a fixing hole 24 is provided on the rear housing 21, and the fixing hole 24 can penetrate the rear housing 21, and the fixing hole 24 can allow the camera assembly 30 to extend out of the rear housing 21. It should be noted that the fixing hole 24 can also be provided on the front housing 23, in which case the camera assembly 30 is exposed from the front housing 23 as a front camera 50, which is not specifically limited here.

[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.

[0026] Please continue reading Figure 3The 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 S and guide a part of the incident light S into the first image sensor 32, and guide the other part into the second image sensor 33.

[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 may be image sensors of the same type or image sensors of different types, which is not specifically limited in this embodiment.

[0028] Please continue reading Figure 3 , the light incident component 31 includes a light splitter 311 and a light incident lens 312. The light incident lens 312 is arranged on the object side of the light splitter 311 and is used to converge the incident light S to increase the light intensity of the incident light S in the optical axis direction. The light incident lens 312 can be a convex lens or other types of lenses, which is not limited in this embodiment. It should be noted that the "incident light S" referred to in this embodiment refers to ambient light. The incident light S enters the first image sensor 32 and / or the second image sensor 33 through the light incident component 31 for imaging. The optical axis direction of the incident light S passing through the light incident lens 312 is set along the Y direction, wherein in this embodiment, the Y direction may be the thickness direction of the electronic device 10. Of course, in some other embodiments, depending on the difference in the setting position of the electronic device 10, the Y direction may also be the length direction or the width direction of the electronic device 10.

[0029] The beam splitter 311 is used to receive the incident light S and separate the incident light S into a first light beam S1 and a second light beam S2. The separated first light beam S1 and the second light beam S2 propagate along different optical paths. The separated first light beam S1 enters the first image sensor 32 along the subsequent optical path, and the separated second light beam S2 enters the second image sensor 33 along the subsequent optical path. In a more specific embodiment, the optical axis of the first light beam S1 and the optical axis of the second light beam S2 separated by the beam splitter 311 are perpendicular to each other.

[0030] In one embodiment, the light splitter 311 can adopt a wavelength splitting method, that is, the light splitter 311 separates the incident light S into a first light S1 and a second light S2 with different wavelengths. It should be noted that the wavelength of the first light S1 and the wavelength of the second light S2 are both within a range of values. For example, the first light S1 can be blue light, and the second light S2 can be other visible light except blue light, or the second light S2 can be blue light, and the first light S1 can be other visible light except blue light. In this embodiment, the light splitter 311 can reflect the second light S2 in the incident light S and transmit the first light S1 in the incident light S to separate the first light S1 from the second light S2. The first light S1 that transmits the light splitter 311 continues to propagate along the Y direction, and the second light S2 reflected by the light splitter 311 propagates along the X direction, wherein the X direction and the Y direction can be substantially perpendicular to each other, and the X direction can be the length direction or the width direction of the electronic device 10, or other directions, which are not limited in this embodiment.

[0031] In some other implementations, the beam splitter 311 may reflect the first light ray S1 in the incident light S and transmit the second light ray S2 in the incident light S to separate the first light ray S1 from the second light ray S2 , which is not limited in this embodiment.

[0032] Specifically, in this embodiment, refer to Figure 4 The light splitter 311 includes a prism 3111 and a semi-transparent and semi-reflective film 3113. The prism 3111 may be a right-angle prism. The prism 3111 has a transflective surface 3112. The transflective surface 3112 may be an inclined surface of the prism 3111. The semi-transparent and semi-reflective film 3113 is disposed on the transflective surface 3112. The semi-transparent and semi-reflective film 3113 may transmit light of a specific wavelength and reflect light of other wavelengths, thereby separating the first light S1 from the second light S2. The angle between the transflective surface and the optical axis direction Y of the incident light S may be 45°.

[0033] In this embodiment, please combine Figure 3 and Figure 4, the first image sensor 32 is arranged corresponding to the light-entering lens 312 in the Y direction (i.e., the direction in which the incident light S is incident on the light-entering lens 312), that is, the optical axis of the first image sensor 32 coincides with the optical axis direction of the light-entering lens 312. The advantage of such an arrangement is that the first light S1 emitted from the light-splitting element 311 can directly enter the first image sensor 32 without setting other elements to guide it. The second image sensor 33 is arranged corresponding to the light-splitting element 311 in the X direction (i.e., the optical axis direction of the second light S2 formed after being separated by the light-splitting element 311), and the propagation direction of the second light S2 entering the second image sensor 33 is perpendicular to the propagation direction of the incident light S entering the light-entering lens 312. In this arrangement, the second image sensor 33 does not need to occupy the space in the Y direction (i.e., the 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.

[0034] In another embodiment, see Figure 5 The light splitter 311 may also be a dichroic plate 3114. The dichroic plate 3114 may also transmit light of a specific wavelength and reflect light of other wavelengths. When the dichroic plate 3114 is set, it may also maintain a 45° angle with the optical axis direction Y of the incident light S. The setting method of other components may refer to the setting method of the prism 3111 mentioned above, and will not be repeated here.

[0035] In another embodiment, the beam splitter 311 may also adopt polarization beam splitting, that is, the beam splitter 311 separates the incident light S into a first light S1 and a second light S2 with different polarization states, for example, the first light S1 may be an S polarized light, and the second light S2 may be a P polarized light, or the second light S2 may be an S polarized light, and the first light S1 may be a P polarized light. The beam splitter 311 may reflect the second light S2 in the incident light S, and transmit the first light S1 in the incident light S, so as to separate the first light S1 from the second light S2, the first light S1 that transmits the beam splitter 311 continues to propagate along the Y direction, and the second light S2 reflected by the beam splitter 311 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.

[0036] In some other implementations, the beam splitter 311 may reflect the first light ray S1 in the incident light S and transmit the second light ray S2 in the incident light S to separate the first light ray S1 from the second light ray S2 , which is not limited in this embodiment.

[0037] Specifically, see Figure 6The beam splitter 311 can be a polarization beam splitter prism 3115. The polarization beam splitter prism 3115 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 multiple times at the Brewster angle, the P-polarized component is completely transmitted, while most of the S-polarized component is reflected (at least 90%). The optical element achieves separation of P-polarized light and S-polarized light.

[0038] In this embodiment, please refer to Figure 1 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 light splitting element 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.

[0039] In this embodiment, the first light guiding device 34 may include a prism L1, a first lens L2, and a second lens L3. The prism L1 is a right-angle prism L1. The hypotenuse of the prism L1 is arranged in contact with the transflective surface of the prism L1. The first light S1 passing through the semi-transparent and semi-reflective film 3113 can directly enter the prism L1. The first lens L2 and the second lens L3 are sequentially arranged between the first image sensor 32 and the prism L1, and the optical axes of the first lens L2 and the second lens L3 coincide. After the first light S1 passes through the semi-transparent and semi-reflective film 3113, it passes through the prism L1, the first lens L2, and the second lens L3 in sequence to enter 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 when the first light S1 enters the first image sensor 32.

[0040] The second light guiding device 35 is disposed between the light splitter 311 and the second image sensor 33 and is located on the light 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 .

[0041] 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.

[0042] Since the incident light S is natural light, which contains infrared light, and the infrared light may cause the image to be reddish when entering the image sensor, in order to improve the imaging quality, the infrared light part of the incident light S 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 S in the light input component 31 to filter out the infrared light.

[0043] In one embodiment, the camera assembly 30 may further include an infrared light cutoff film (not shown), which is disposed on the surface of the incident lens 312 and located on the image side of the incident lens 312. When the incident light S enters the incident lens 312, the infrared light in the incident light S 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.

[0044] In some other embodiments, the infrared light cut-off film may also be disposed on any optical element in the first light guiding device 34 and the second light guiding 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.

[0045] 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.

[0046] 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.

[0047] In the camera assembly 30 provided in the above embodiment, the light splitter 311 of the light input assembly 31 separates the incident light S into a first light beam S1 and a second light beam S2, and the first light beam S1 and the second light beam S2 enter the first image sensor 32 and the second image sensor 33 respectively for imaging. Since the first image sensor 32 and the second image sensor 33 share a set of light input assembly 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.

[0048] In another embodiment, see Figure 7 The camera assembly 30 may also include a second reflector 37. The second reflector 37 is disposed on the optical path of the second light S2 and is used to reflect the second light S2. The second image sensor 33 receives the second light S2 reflected by the second reflector 37 and forms an image. After being reflected by the second reflector 37, the propagation direction of the second light S2 changes. Therefore, the setting position of the second image sensor 33 can be adjusted accordingly. Specifically in this embodiment, the second light S2 reflected by the second reflector 37 propagates along the Y direction and is opposite to the propagation direction of the incident light S entering the light input 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 input lens 312 are located on the same side of the second reflector 37. Compared with this arrangement, Figure 3 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.

[0049] The second reflector 37 can 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 second light S2 can be set as needed, and this embodiment does not limit this.

[0050] In another embodiment, see Figure 8 The camera assembly 30 may further include a second reflector 37, which is disposed on the optical path of the second light S2 and is used to reflect the second light S2. The second image sensor 33 receives the second light S2 reflected by the second reflector 37 and forms an image. After being reflected by the second reflector 37, the propagation direction of the second light S2 changes, so the setting position of the second image sensor 33 can be adjusted accordingly. Specifically in this embodiment, the second light S2 reflected by the second reflector 37 propagates along the Y direction, and has the same propagation direction as the incident light S 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. The second image sensor 33 and the light-entering lens 312 are located on opposite sides 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.

[0051] In another embodiment, see Fig. 9 The light incident component 31 further includes a first reflector 313, which is disposed on the object side of the beam splitter 311 and on the image side of the light incident lens 312. The first reflector 313 is used to reflect the incident light S. After the incident light S enters the light incident lens 312, it enters the first reflector 313. The first reflector 313 reflects the incident light S toward the beam splitter 311, and then the incident light S enters the beam splitter 311. Since the first reflector 313 deflects the propagation direction of the incident light S, the setting position of the beam splitter 311, the first image sensor 32 or the second image sensor 33 can be adjusted to adapt to different usage environments.

[0052] Specifically in this embodiment, the first reflector 313 and the incident lens 312 are correspondingly arranged in the optical axis direction (i.e., the Y direction) of the incident light S. The first reflector 313 is a right-angle prism, and a reflective film is arranged on the inclined surface of the right-angle prism to reflect the incident light S. The incident light S after being reflected propagates along the X direction. The beam splitter 311 is arranged in contact with the first reflector 313. After the incident light S enters the beam splitter 311, it is separated into a first light S1 and a second light S2. The first light S1 is reflected by the beam splitter 311. The reflected first light S1 is emitted along the Y direction and enters the first image sensor 32. The second light S2 passes through the beam splitter 311 and continues to propagate along the X direction and enters the second image sensor 33. The first image sensor 32 is arranged on one side of the beam splitter 311, and the first image sensor 32 and the incident lens 312 are located on the same side of the beam splitter 311. The first light guiding device 34 is arranged between the beam splitter 311 and the first image sensor 32. This arrangement can more reasonably utilize the space between the light splitting element 311 and the first image sensor 32 to set the first light guiding device 34, thereby saving the size of the entire camera assembly 30 in the Y direction and further reducing the volume of the camera assembly 30.

[0053] 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 second light S2 and is used to reflect the second light S2. The second image sensor 33 receives the second light S2 reflected by the second reflector 37 and forms an image. After being reflected by the second reflector 37, the propagation direction of the second light S2 changes. Therefore, the setting position of the second image sensor 33 can be adjusted accordingly. Specifically in this embodiment, the second light S2 reflected by the second reflector 37 propagates along the Y direction and is the same as the propagation direction of the incident light S entering the light input 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 input lens 312 are located on opposite sides of the second reflector 37. Compared with this arrangement, Fig. 9 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.

[0054] The second reflector 37 can 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 second light S2 can be set as needed, and this embodiment does not limit this.

[0055] 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 second light S2 and is used to reflect the second light S2. The second image sensor 33 receives the second light S2 reflected by the second reflector 37 and forms an image. After being reflected by the second reflector 37, the propagation direction of the second light S2 changes, so the setting position of the second image sensor 33 can be adjusted accordingly. Specifically in this embodiment, the second light S2 reflected by the second reflector 37 propagates along the Y direction, and is opposite to the propagation direction of the incident light S 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. 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 one side of the light incident lens 312 of the second reflector 37 will not increase the size of the camera assembly 30 in the Y direction.

[0056] The camera assembly 30 mentioned above, by sharing the light incident assembly 31, the first image sensor 32 and the second image sensor 33, reduces the number of components during the setting process, thereby reducing the volume of the entire camera assembly 30, thereby reducing the space occupied when set in the electronic device 10.

[0057] It should be noted that in some other embodiments, the number of image sensors may be more than two, 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 311, the first light S1 and the second light S2 are split again, so that the purpose of multiple image sensors sharing the light incident component 31 is achieved. In this embodiment, the number of image sensors is not limited.

[0058] 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. The camera fixing part is provided with a camera fixing hole, and the camera fixing hole may be used to set the camera assembly 30. The camera fixing hole is a through hole and passes through the camera fixing part, so that the camera assembly 30 may be exposed from the camera fixing hole to collect external images, and the number of camera fixing holes may be one, or any other number more than one, which is not limited here.
