Abstract
Description
Technical Field
[0001] This application relates to the field of optical technology, specifically to a prism assembly, a periscope camera module, and an electronic device. Background Technology
[0002] In the field of optics, curved prisms are an important optical component widely used in periscope camera modules, and their performance directly affects the imaging quality and efficiency of the entire optical system. Currently, the industry mostly uses glass molding, glass bonding, or glass grinding methods to process curved prisms. However, glass molding, glass bonding, and glass grinding processes are complex, difficult to process, have low production efficiency, and relatively high production costs. Utility Model Content
[0003] In view of the above, it is necessary to propose a prism assembly, a periscope camera module, and an electronic device to reduce the manufacturing difficulty and increase the freedom of optical design.
[0004] A first aspect of this application provides a prism assembly, comprising: a prism having an incident surface; a first lens disposed on one side of the incident surface and opposite to the incident surface, wherein at least one of the object-side surface and the image-side surface of the first lens is aspherical; and a first support member disposed between the incident surface and the first lens, wherein opposite sides of the first support member are respectively connected to the optically ineffective areas of the incident surface and the first lens.
[0005] In the prism assembly provided in this application embodiment, by designing at least one of the object-side and image-side surfaces of the first lens as aspherical, the limitations imposed by traditional glass molding, gluing, and grinding methods on aspherical design are eliminated. This allows the aspherical design to be no longer constrained by the prism's own processing technology, enabling flexible design of aspherical structures on the object-side and image-side surfaces of the first lens according to actual needs. This increases the freedom of optical design and helps improve image quality. Furthermore, the first support member connects the optically ineffective areas of the prism and the first lens, avoiding obstruction or interference with the optically effective area of the first lens and ensuring smooth light transmission between the incident surfaces of the first lens and the prism. Moreover, by designing the prism and the first lens separately, their respective processing can be carried out independently. The prism no longer needs to undergo complex molding, gluing, or grinding processes to form an aspherical structure, reducing the processing difficulty of the prism, helping to improve production efficiency, reduce production costs, and increase assembly yield.
[0006] In some embodiments, the optically effective area of the image side of the first lens at the position where the distance from the incident surface is smallest in the optical axis direction is on the same plane as the connection position between the first support member and the prism.
[0007] In this way, the relative positions of the first lens and the prism in the optical axis direction can be controlled, minimizing the distance between the incident surfaces of the first lens and the prism, thereby contributing to the miniaturization of the prism assembly.
[0008] In some embodiments, the prism further includes an exit surface disposed adjacent to the incident surface, and the prism assembly further includes a second lens, which is spaced apart on one side of the exit surface and disposed opposite to the exit surface.
[0009] In this way, aspherical structures can be flexibly designed on the object side and image side of the second lens according to actual needs, further improving the freedom of optical design and thus improving imaging quality.
[0010] In some embodiments, the prism assembly further includes a second support member disposed between the exit surface and the second lens, wherein opposite sides of the second support member are respectively connected to the optically ineffective areas of the exit surface and the second lens.
[0011] Thus, the second support provides a stable connection and support between the second lens and the exit surface of the prism, and the connection position is located in the optically ineffective area, avoiding obstruction or interference to light transmission.
[0012] In some embodiments, the optically effective area of the image side of the second lens at the position with the smallest distance from the exit surface in the optical axis direction is on the same plane as the connection position between the second support member and the prism.
[0013] In this way, the relative position of the second lens and the prism's exit surface in the optical axis direction can be controlled, minimizing the distance between the second lens and the prism's exit surface, thus contributing to the miniaturization of the prism assembly.
[0014] In some embodiments, the first lens has a first cut surface at one end near the second lens, and the second lens has a second cut surface at one end near the first lens, with the first cut surface and the second cut surface abutting each other.
[0015] Thus, the contact between the first and second cut surfaces forms an additional positioning and support structure between the first and second lenses, further improving the relative positional accuracy of the first and second lenses in the radial direction and enhancing the structural stability of the entire prism assembly.
[0016] In some embodiments, the first support member includes at least one first support portion. When there is one first support portion, the first support portion is annular and surrounds the periphery of the optically effective area of the first lens. When there are multiple first support portions, the multiple first support portions are annularly spaced and surround the periphery of the optically effective area of the first lens; and / or,
[0017] The second support member includes at least one second support portion. When there is one second support portion, the second support portion is annular and surrounds the periphery of the optically effective area of the second lens. When there are multiple second support portions, the multiple second support portions are arranged annularly at intervals and surround the periphery of the optically effective area of the second lens.
[0018] In this way, the ring-shaped or intermittently spaced support parts can provide uniform and stable support to the lens without obstructing the effective optical area, so that the lens is radially balanced, reducing lens deformation caused by uneven force and ensuring the optical performance of the lens.
[0019] In some embodiments, a first blackening layer is provided on both the side of the first support member near the optically effective area of the first lens and the optically ineffective area of the first lens; and / or,
[0020] The second support member has a second blackening layer on the side near the optically effective area of the second lens and on the optically ineffective area of the second lens.
[0021] In this way, the blackening layer can effectively absorb stray light generated in the optically ineffective area, preventing stray light from entering the optically effective area after being reflected or scattered inside the prism assembly, thereby reducing the interference of stray light on image quality.
[0022] A second aspect of this application provides a periscope camera module, comprising:
[0023] The prism assembly as described in any of the above technical solutions; and
[0024] A photosensitive component is located on the light-emitting side of the prism component.
[0025] The periscope camera module provided in this application includes the aforementioned prism assembly. By designing at least one of the object-side and image-side surfaces of the first lens as aspherical, the prism assembly overcomes the limitations imposed by traditional glass molding, gluing, and grinding methods on aspherical design. This allows the aspherical design to be flexibly designed on both the object-side and image-side surfaces of the first lens according to actual needs, increasing the freedom of optical design and contributing to improved image quality. Furthermore, the first support member connects the optically ineffective areas of the prism and the first lens, avoiding obstruction or interference with the optically effective area of the first lens and ensuring smooth light transmission between the incident surfaces of the first lens and the prism. Moreover, by designing the prism and the first lens separately, their respective processing can be carried out independently. The prism no longer needs to undergo complex molding, gluing, or grinding processes to form an aspherical structure, reducing the processing difficulty of the prism, improving production efficiency, reducing production costs, and increasing assembly yield.
[0026] A third aspect of this application provides an electronic device, including: a housing; and a periscope camera module as described above, the periscope camera module being disposed within the housing.
[0027] The electronic device provided in this application includes the aforementioned prism assembly. By designing at least one of the object-side and image-side surfaces of the first lens as aspherical, the prism assembly overcomes the limitations imposed by traditional glass molding, gluing, and grinding methods on aspherical design. This allows the aspherical design to be flexibly designed on both the object-side and image-side surfaces of the first lens according to actual needs, increasing the freedom of optical design and contributing to improved image quality. Furthermore, the first support member connects the optically ineffective areas of the prism and the first lens, avoiding obstruction or interference with the optically effective area of the first lens and ensuring smooth light transmission between the incident surfaces of the first lens and the prism. Moreover, by designing the prism and the first lens separately, their respective processing can be carried out independently. The prism no longer needs complex molding, gluing, or grinding processes to form an aspherical structure, reducing the processing difficulty of the prism, improving production efficiency, reducing production costs, and increasing assembly yield.

[0038] The embodiments of this application will be described in detail below with reference to the accompanying drawings.
[0039] Please see Figure 1The first aspect of this application provides a prism assembly 10, including a prism 11, a first lens 12 and a first support member 13.
[0040] Please see also Figure 2 The prism 11 has an incident surface 111, which is a plane. In some embodiments, the prism 11 is a right-angle prism. In some embodiments, the prism 11 is a conventional prism. A first lens 12 is disposed on one side of the incident surface 111 and is disposed opposite to the incident surface 111. At least one of the object-side surface S1 and the image-side surface S2 of the first lens 12 is aspherical. In some embodiments, only the image-side surface S2 of the first lens 12 is aspherical. In some embodiments, only the object-side surface S1 of the first lens 12 is aspherical. In some embodiments, both the object-side surface S1 and the image-side surface S2 of the first lens 12 are aspherical. A first support member 13 is disposed between the incident surface 111 and the first lens 12. The opposite sides of the first support member 13 are respectively connected to the optically ineffective region 12b of the incident surface 111 and the first lens 12. In some embodiments, the first support member 13 and the first lens 12 are an integral structure. In some embodiments, the first support member 13 and the first lens 12 are separate structures, with the first support member 13 bonded to the image-side surface S2 of the first lens 12. In some embodiments, the first support member 13 and the prism 11 are an integral structure. In some embodiments, the first support member 13 and the prism 11 are separate structures, with the first support member 13 bonded to the incident surface 111 of the prism 11. In some embodiments, both the first support member 13 and the first lens 12 are made of plastic.
[0041] In the prism assembly 10 provided in this application embodiment, by designing at least one of the object-side surface S1 and the image-side surface S2 of the first lens 12 as an aspherical surface, the limitations imposed on aspherical surface design by traditional glass molding, bonding, grinding, and other methods are eliminated. This allows the aspherical surface design to be no longer constrained by the processing technology of the prism 11 itself, enabling flexible design of aspherical structures on the object-side surface S1 and the image-side surface S2 of the first lens 12 according to actual needs, thereby improving the degree of freedom in optical design and contributing to improved image quality. Furthermore, the first support member 13 connects the optically ineffective area 12b of the prism 11 and the first lens 12, avoiding obstruction or interference to the optically effective area 12a of the first lens 12, ensuring smooth transmission of light between the incident surface 111 of the first lens 12 and the prism 11. Furthermore, the prism 11 and the first lens 12 are designed separately, and their respective processing can be carried out independently. The prism 11 no longer needs to go through complex molding, gluing or grinding processes to form an aspherical structure, which reduces the processing difficulty of the prism 11, helps to improve production efficiency, reduce production costs and improve assembly yield.
[0042] In some embodiments, the position where the optically effective area 12a of the image-side surface S2 of the first lens is at its minimum distance from the incident surface 111 in the optical axis direction is on the same plane as the connection position between the first support member 13 and the prism 11. In this way, the relative position of the first lens 12 and the prism 11 in the optical axis direction can be controlled to minimize the distance between the incident surfaces 111 of the first lens 12 and the prism 11, that is, to minimize the thickness of the first lens 12 and the prism 11, thereby contributing to the miniaturization of the prism assembly 10.
[0043] In this embodiment, both the image-side surface S2 and the object-side surface S1 of the first lens 12 are convex at the optical axis. It can be understood that in some embodiments, both the image-side surface S2 and the object-side surface S1 of the first lens 12 are concave at the optical axis. In this case, a curvature point is provided outside the optical axis of the optically effective area 12a of the image-side surface S2 of the first lens 12. This curvature point is on the same plane as the connection position between the first support member 13 and the prism 11.
[0044] In some embodiments, the prism 11 further includes an exit surface 112 adjacent to the incident surface 111, the exit surface 112 being planar. The prism assembly 10 also includes a second lens 14, which is spaced apart on one side of the exit surface 112 and opposite to it. In some embodiments, only the image-side surface S4 of the second lens 14 is aspherical. In some embodiments, only the object-side surface S3 of the second lens 14 is aspherical. In some embodiments, both the object-side surface S3 and the image-side surface S4 of the second lens 14 are aspherical. Thus, aspherical structures can be flexibly designed on the object-side surface S3 and the image-side surface S4 of the second lens 14 according to actual needs, further improving the freedom of optical design and thereby improving image quality.
[0045] In this embodiment, the exit surface 112 is arranged perpendicularly to the incident surface 111. The prism 11 also includes a reflecting surface 113, which is an inclined surface and is connected to the incident surface 111 and the exit surface 112 respectively, for reflecting the light rays incident from the incident surface 111.
[0046] In some embodiments, the prism assembly 10 further includes a second support member 15, which is disposed between the exit surface 112 and the second lens 14. The opposite sides of the second support member 15 are respectively connected to the optically ineffective regions 14b of the exit surface 112 and the second lens 14. Thus, the second support member 15 provides a stable connection support between the second lens 14 and the exit surface 112 of the prism 11, and the connection position is located in the optically ineffective region 14b, avoiding obstruction or interference to light transmission.
[0047] In some embodiments, the second support member 15 and the second lens 14 are an integral structure. In some embodiments, the second support member 15 and the second lens 14 are separate structures, with the second support member 15 bonded to the second lens 14. In some embodiments, both the second support member 15 and the second lens 14 are made of plastic.
[0048] In some embodiments, the position where the optically effective area 14a of the image-side surface S4 of the second lens is at its minimum distance from the exit surface 112 in the optical axis direction is on the same plane as the connection position between the second support member 15 and the prism 11. This allows control over the relative positions of the exit surfaces 112 of the second lens 14 and the prism 11 in the optical axis direction, minimizing the distance between them, i.e., minimizing their thickness, thereby contributing to the miniaturization of the prism assembly 10.
[0049] In this embodiment, the object-side surface S3 of the second lens 14 is convex along the optical axis, and the image-side surface S4 is concave along the optical axis. It can be understood that in some embodiments, the object-side surface S3 of the second lens 14 is concave along the optical axis. In this case, a curvature point can be provided outside the optical axis of the optically effective area 14a of the object-side surface S3 of the second lens 14. This curvature point is on the same plane as the connection point between the second support member 15 and the prism 11.
[0050] In some embodiments, the first lens 12 has a first cross-section 121 at one end near the second lens 14, and the second lens 14 has a second cross-section 141 at one end near the first lens 12, with the first cross-section 121 and the second cross-section 141 abutting each other. This abutment between the first cross-section 121 and the second cross-section 141 forms an additional positioning and support structure between the first lens 12 and the second lens 14, further improving the relative positional accuracy of the first lens 12 and the second lens 14 in the radial direction and enhancing the structural stability of the entire prism assembly 10.
[0051] In some embodiments, the first cut surface 121 and the second cut surface 141 are both planes. In some embodiments, the first cut surface 121 and the second cut surface 141 are mating inclined surfaces. In some embodiments, the first cut surface 121 and the second cut surface 141 are mating stepped surfaces.
[0052] Please see also Figure 3 In some embodiments, the first support member 13 includes at least one first support portion 131. When there is one first support portion 131, the first support portion 131 is annular and surrounds the periphery of the optically effective area 12a of the first lens 12. When there are multiple first support portions 131, the multiple first support portions 131 are arranged annularly at intervals and surround the periphery of the optically effective area 12a of the first lens 12; and / or,
[0053] The second support member 15 includes at least one second support portion 151. When there is one second support portion 151, the second support portion 151 is annular and surrounds the periphery of the optical effective area 14a of the second lens 14. When there are multiple second support portions 151, the multiple second support portions 151 are arranged annularly at intervals and surround the periphery of the optical effective area 14a of the second lens 14.
[0054] In this way, the ring-shaped or intermittently spaced support parts can provide uniform and stable support to the lens without obstructing the effective optical area, so that the lens is radially balanced, reducing lens deformation caused by uneven force and ensuring the optical performance of the lens.
[0055] In this embodiment, there are two first bearing portions 131 and two bearing portions 151, which are arranged in a ring-shaped interval. It can be understood that in other embodiments, there are three, four, or five first bearing portions 131 and two bearing portions 151, but it is not limited to these.
[0056] In some embodiments, a first blackening layer 122 is provided on both the side of the first bearing member 13 near the optically effective area 12a of the first lens 12 and the optically ineffective area 12b of the first lens 12; and / or,
[0057] The second support member 15 is provided with a second blackening layer 142 on the side of the second lens 14 near the optically effective area 14a and the optically ineffective area 14b of the second lens 14.
[0058] In this way, the blackening layer can effectively absorb stray light generated in the optically ineffective area, preventing stray light from entering the optically effective area after being reflected or scattered inside the prism assembly 10, thereby reducing the interference of stray light on the imaging quality.
[0059] In some embodiments, the first blackening layer 122 is provided only on the side of the first support member 13 near the optically effective area 12a of the first lens 12, and the second blackening layer 142 is provided only on the side of the second support member 15 near the optically effective area 14a of the second lens 14.
[0060] In this embodiment, the blackening layer is formed by applying ink, but it is not limited to this method.
[0061] Please see Figure 4 A second aspect of this application provides a periscope camera module 100, including a prism assembly 10, a lens assembly 20, and a photosensitive assembly 30. The lens assembly 20 is disposed on one side of the prism assembly 10, and the photosensitive assembly 30 is disposed on the light-emitting side of the photosensitive assembly 30 away from the prism assembly 10. The lens assembly 20 consists of two spaced-apart lenses and a prism, and the photosensitive assembly 30 is a photosensitive chip.
[0062] The periscope camera module 100 provided in this application embodiment includes the aforementioned prism assembly 10. The prism assembly 10, by designing at least one of the object-side surface S1 and image-side surface S2 of the first lens 12 as an aspherical surface, overcomes the limitations imposed on aspherical design by traditional glass molding, bonding, and grinding methods. This allows the aspherical design to be no longer constrained by the processing technology of the prism 11 itself, enabling flexible design of aspherical structures on the object-side surface S1 and image-side surface S2 of the first lens 12 according to actual needs. This improves the freedom of optical design and helps to improve image quality. Furthermore, the first support member 13 connects the optically ineffective area 12a of the prism 11 and the first lens 12, avoiding obstruction or interference to the optically effective area 12a of the first lens 12, ensuring smooth light transmission between the incident surface 111 of the first lens 12 and the prism 11. Furthermore, the prism 11 and the first lens 12 are designed separately, and their respective processing can be carried out independently. The prism 11 no longer needs to go through complex molding, gluing or grinding processes to form an aspherical structure, which reduces the processing difficulty of the prism 11, helps to improve production efficiency, reduce production costs and improve assembly yield.

[0064] The electronic device 1000 provided in this application embodiment includes the prism assembly 10 described above. The prism assembly 10, by designing at least one of the object-side surface S1 and image-side surface S2 of the first lens 12 as an aspherical surface, overcomes the limitations imposed on aspherical design by traditional glass molding, bonding, and grinding methods.
