[0022] According to a second aspect of this disclosure, an electronic device is provided, including a camera module as described in the first aspect of this disclosure.

[0023] The technical solutions provided by the embodiments of this disclosure may include the following beneficial effects: By setting the prism of the camera module as an integrated prism, this disclosure reduces the imaging blemishes caused by the splicing gaps between the various components of the camera module, which is conducive to improving the image clarity. At the same time, compared with the spliced ​​prism structure, setting the prism as an integrated structure increases the optical path of the camera module while ensuring that the overall size of the prism remains unchanged, thereby improving the imaging magnification of the camera module and enhancing the user's experience and shooting experience.

[0024] It should be understood that the above general description and the following detailed description are exemplary and explanatory only, and are not intended to limit this disclosure. Attached Figure Description

[0025] The accompanying drawings, which are incorporated in and form a part of this specification, illustrate embodiments consistent with this disclosure and, together with the description, serve to explain the principles of this disclosure.

[0027] Figure 2 This is a schematic diagram of a prism shown according to a first exemplary embodiment.

[0028] Figure 3 This is a schematic diagram of a prism shown according to a second exemplary embodiment.

[0030] Figure 5 This is a schematic diagram of a prism shown according to a fourth exemplary embodiment. Detailed Implementation

[0031] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this disclosure. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this disclosure as detailed in the appended claims.

[0032] Currently, as users' demand for camera functions in electronic devices gradually increases, more and more electronic devices are upgrading the hardware performance of their camera modules. For example, they are setting up periscope camera modules to give them higher optical zoom capabilities, thereby enabling them to shoot objects at greater distances and improve shooting results.

[0033] In related technologies, in order to achieve higher imaging magnification and clarity, the optical path of a periscope camera module needs to be longer than that of a conventional camera module, which means it is longer in size. As a result, the size of a periscope camera module is much larger than that of a conventional camera module, which reduces the aesthetics of electronic devices and causes greater inconvenience to users. In addition, due to the more complex structure of the periscope camera module and the gaps between the various components, it is more susceptible to contamination by dust, oil, etc., which can lead to blemishes during imaging and deteriorate the shooting effect.

[0034] To address the aforementioned technical issues, this disclosure provides a camera module and electronic device. By designing the prism of the camera module as a single, integrated prism, it reduces imaging blemishes caused by splicing gaps between the various components of the camera module, thereby improving image clarity. Furthermore, compared to a spliced ​​prism structure, while maintaining the same overall prism size, a single-piece prism structure increases the optical path of the camera module, improving its magnification and enhancing the user experience and shooting experience. It is understandable that, compared to camera modules with spliced ​​prism structures, using the single-piece prism structure of this disclosure, while maintaining the same magnification, can reduce the overall size of the camera module, facilitating miniaturization.

[0035] According to an exemplary embodiment, such as Figures 1-5 As shown, this embodiment of the present disclosure provides a camera module, which is a periscope camera module. That is, it uses a reflector or prism to change the path of light, thereby extending the length of the light transmission path and achieving a longer focal length. This enables electronic devices to have stronger optical zoom capabilities and higher magnification. Optical zoom refers to physical zoom by adjusting the distance between lenses. Unlike digital zoom, which uses software algorithms to crop and enlarge the image, optical zoom produces clearer images without damaging image quality or losing image details.

[0036] The camera module includes a lens assembly 10, a prism 20, and a photosensitive assembly 30. The prism 20 has an inclined surface 201. Incident light 41 is incident on the prism 20 along a first direction and then reflected by the inclined surface 201 as outgoing light 42 along a second direction. A first preset angle exists between the first and second directions. The first preset angle can be adjusted according to actual needs; for example, the first preset angle can be 90°, meaning the first direction is perpendicular to the second direction. Figure 1 Taking the directions shown as an example, the first direction is vertical and the second direction is horizontal. By changing the propagation direction of the light path, the optical path is extended, thereby achieving a higher imaging magnification. Of course, it is understandable that the first preset angle can also be other angles, as long as the incident light 41 is incident along the first direction and, after reflection, the emitted light 42 emitted along the second direction can be received by the photosensitive component 30. The position of the photosensitive component 30 can be adjusted according to the different angles of the first preset angle. For example, when it is necessary to avoid certain structures, the tilt angle of the tilted surface 201, that is, the first preset angle, can be adjusted to adjust the propagation direction of the light path, thereby adjusting the position of the photosensitive component 30 accordingly to achieve avoidance.

[0037] The prism 20 is a one-piece structure. The lens assembly 10 is located at the light-incident end 202 of the prism 20, and the photosensitive assembly 30 is located at the light-outcrowding end 203 of the prism 20. The photosensitive assembly 30 is used to receive the outgoing light 42. Because the prism 20 is a one-piece structure, there are no gaps caused by splicing different structures in the light propagation path, and there is no need to set a support structure for the prism 20. This shortens the length of the prism 20 along the second direction, reduces the overall length of the camera module, and helps to reduce the size of the camera module. Alternatively, it can achieve a longer optical path and a higher magnification within the same size, improving the user experience. The one-piece prism is also less susceptible to contamination by dust, oil, and other impurities, thus improving the shooting effect and image quality.

[0038] In this embodiment of the disclosure, by setting the prism of the camera module as an integrated prism, the imaging blemishes caused by the splicing gaps between the various components of the camera module are reduced, which is beneficial to improving the imaging clarity. At the same time, the optical path of the camera module is increased, so that when the required imaging magnification is achieved, the overall length of the camera module is reduced, which is beneficial to the miniaturization of the camera module and improves the user experience and ease of use.

[0039] In some embodiments, the prism 20 is provided with a first lens 21. The first lens 21 is disposed along the propagation path from the incident light 41 to the emitted light 42. The first lens 21 disposed on the prism 20 can be used in conjunction with the lens assembly 10 to zoom, thereby improving the versatility of the camera module's focal length adjustment.

[0040] The first lens 21 can be disposed at at least one of the light-incident end 202 and the light-outceasing end 203. In one example, such as Figure 2 , 3 As shown, the first lens 21 is disposed at the light incident end 202. In another example, as... Figure 4 As shown, the first lens 21 is disposed at the light-emitting end 203. In yet another example, as... Figure 5 As shown, the first lens 21 is respectively disposed at the light incident end 202 and the light emitting end 203. By disposing of the first lens 21 at at least one of the light incident end 202 and the light emitting end 203, it can cooperate with other lenses in the lens assembly 10 to adjust the light path and improve the imaging effect.

[0041] In some embodiments, the first lens 21 is located on the inner or outer wall surface of the prism 20. In one example, the first lens 21 is a separate lens disposed on the prism 20. In another example, the first lens 21 is formed by etching the prism 20.

[0042] When etching the prism 20 to form the first lens 21, etching can be performed on the surface of the prism 20 outside the position corresponding to the first lens 21, such as... Figure 2 , 5 As shown, a first lens 21 is formed on the outer wall surface of the prism 20. Alternatively, the surface of the prism 20 can be etched at the position corresponding to the first lens 21, such as... Figure 3 , 4 As shown, a first lens 21 is formed on the inner wall surface of the prism 20. Additionally, depending on the requirements of the camera module, the first lens 21 can be configured as a convex or concave lens. The specific dimensions, focal length, and other parameters of the first lens 21 can be adjusted by those skilled in the art according to actual needs, and this embodiment does not impose excessive limitations in this regard.

[0043] In some embodiments, the lens assembly 10 includes a second lens (not shown) and an adjustment assembly 11. The second lens is mounted on the adjustment assembly 11, which drives the second lens to move along the optical axis of the lens assembly 10. The adjustment assembly 11 may be, for example, an electric motor fixedly connected to the second lens. The fixed connection may be, for example, a direct adhesive connection or a bracket-mounted connection between the adjustment assembly 11 and the second lens. The adjustment assembly 11 can adjust the distance between the second lens and the object to be photographed, thereby achieving optical zoom.

[0044] In some embodiments, the lens assembly 10 further includes at least one fixed lens (not shown). The position of the fixed lens remains constant relative to the prism 20. The fixed lens and the second lens are stacked and coaxially arranged. The adjustment component 11 can drive the second lens to move, thereby adjusting the distance between the second lens and the fixed lens to adjust the overall focal length of the lens assembly 10. This allows for focusing on objects at different distances, resulting in clearer images and improved shooting effects. Furthermore, the first lens 21 in the aforementioned prism 20 can be positioned in different locations. By positioning the first lens 21 in different positions and cooperating with the fixed lens and the second lens of the lens assembly 10, multiple focusing distances can be achieved, enabling richer focal length adjustment methods, enhancing the user's shooting experience, and meeting various shooting needs.

[0045] In some embodiments, a circuit structure (not shown) is formed on the surface of the prism 20 by etching. The circuit structure is electrically connected to the lens assembly 10 and the photosensitive assembly 30, respectively. By etching the circuit structure on the surface of the prism 20, the circuit wiring can avoid affecting light transmission or occupying more space, thus improving the space utilization of the camera module. The photosensitive assembly 30 may include a filter, a photosensitive chip, and a circuit board. The filter and the circuit board are respectively disposed on both sides of the photosensitive chip. The filter is disposed on the side of the photosensitive chip closer to the prism 20. The incident light 41 is reflected by the inclined surface 201 of the prism 20 into an outgoing light 42. After the outgoing light 42 is emitted from the light emitting end 203 of the prism 20, it passes through the filter and the photosensitive chip. The filter is used to filter out stray light and improve image quality. The photosensitive chip is used to receive the outgoing light 42 and perform photosensitive processing, converting the light signal into an electrical signal. The electrical signal is transmitted through the circuit board to other components with imaging functions for imaging. The circuit board can also be electrically connected to the adjustment component 11 of the lens assembly 10 through the circuit structure, control the operation of the adjustment component 11, and thereby drive the second lens to move to achieve focal length adjustment.

[0046] In some embodiments, the connection method between the circuit structure and the lens assembly 10 and the photosensitive assembly 30 includes at least one of soldering and conductive adhesive bonding. In one example, the circuit structure is soldered to the lens assembly 10 and bonded to the photosensitive assembly 30 using conductive adhesive. In another example, both the circuit structure and the lens assembly 10 and the photosensitive assembly 30 are soldered. In yet another example, both the circuit structure and the lens assembly 10 and the photosensitive assembly 30 are simultaneously connected using both soldering and conductive adhesive bonding. The specific connection method between the circuit structure and the lens assembly 10 and the photosensitive assembly 30 can be selected by those skilled in the art according to actual needs, and this disclosure does not impose excessive limitations on this aspect.

[0047] The circuit structure is electrically connected to the lens assembly 10 and the photosensitive assembly 30, respectively. Specifically, the circuit structure is electrically connected to the adjustment component 11 of the lens assembly 10 and to the circuit board of the photosensitive assembly 30. Soldering connections can be made using methods such as soldering, zinc soldering, or aluminum soldering. Through heating, high temperature, or high pressure, the circuit structure is joined to the lens assembly 10 or the photosensitive assembly 30 using metal, alloy, or other conductive thermoplastic materials. Conductive adhesives generally refer to adhesives that have a certain degree of conductivity after curing or drying. Based on the type of conductive particles in the conductive adhesive, it can be divided into silver-based conductive adhesives, gold-based conductive adhesives, copper-based conductive adhesives, and carbon-based conductive adhesives, etc. Conductive adhesives are mainly composed of a resin matrix, conductive particles, dispersing additives, and auxiliaries. No soldering is required during connection, thus preventing deformation of the parts to be connected due to excessive temperature, making it more convenient to use and more widely applicable. Of course, it is understood that those skilled in the art can choose appropriate electrical connection methods according to actual production and cost needs, and this disclosure does not impose excessive limitations on this aspect.

[0048] In some embodiments, a light-shielding layer (not shown) is provided on the outer surface of the prism 20. The light-shielding layer can be a light-shielding coating applied to the outer surface of the prism 20, such as blackening the outer surface of the prism 20. The light-shielding layer covers the circuit structure and avoids the light incident end 202 and the light emitting end 203, thereby preventing external stray light from interfering with imaging without affecting light transmission, and improving the shooting effect and image quality.

[0049] In some embodiments, the lens assembly 10 and the prism 20 are bonded together by a first transparent adhesive layer (not shown in the figure), and the photosensitive assembly 30 and the prism 20 are bonded together by a second transparent adhesive layer (not shown in the figure). Since the lens assembly 10 and the prism 20, and the photosensitive assembly 30 and the prism 20 are directly bonded together, there are no gaps between the prism 20 and the lens assembly 10 or the photosensitive assembly 30. This prevents dust from entering between the lens assembly 10 and the prism 20, and between the photosensitive assembly 30 and the prism 20, thereby ensuring that there are no impurities in the light transmission path, reducing the probability of blemishes during imaging, and improving image quality.

[0050] In one example, the lens assembly 10 and the prism 20 are bonded together using a first transparent adhesive layer. In another example, the photosensitive assembly 30 and the prism 20 are bonded together using a second transparent adhesive layer. In yet another example, the lens assembly 10 and the prism 20 are bonded together using the first transparent adhesive layer, and the photosensitive assembly 30 and the prism 20 are bonded together using the second transparent adhesive layer. The first and second transparent adhesive layers can be colorless and transparent adhesives with a light transmittance of over 90%, such as silicone, polyurethane, or epoxy resin. Using transparent adhesive layers for bonding makes the production process more convenient and faster, and improves assembly efficiency. Furthermore, because the adhesive layers are transparent and have high light transmittance, they also avoid affecting the light transmission effect, ensuring image quality.

[0051] In some embodiments, the prism 20 includes a first portion 22 and a second portion 23 connected together. For example... Figure 1 As shown, the light incident end 202 and the inclined surface 201 are located in the first part 22, and the light emitting end 203 is located in the second part 23. The light incident end 202 is located on the first surface 221 of the first part 22, and the inclined surface 201 and the first surface 221 have a second preset angle. The second part 23 includes a second surface 231 and a third surface 232 connected together. The first surface 221 and the second surface 231 are located in the same plane, and the third surface 232 is located on the side of the second part 23 away from the first part 22. The third surface 232 and the second surface 231 have a third preset angle.

[0052] The second and third preset angles can be set by those skilled in the art according to actual needs. The second preset angle is preferably 45°, which ensures that the incident light 41 and the emitted light 42 are perpendicular to each other. The third preset angle is preferably 90°, which ensures that the emitted light 42 is perpendicular to the surface of the light emitting end 203, thus preventing light deflection. Of course, it is understood that the second and third preset angles can also be adjusted, as long as the emitted light 42 is received by the photosensitive component 30. This embodiment does not impose excessive limitations on this.

[0053] According to an exemplary embodiment, such as Figures 1-5As shown, this disclosure provides an electronic device, such as a mobile terminal, camera, laptop computer, or other electronic device with shooting capabilities. The electronic device includes a camera module as described in the above embodiments. The camera module includes a lens assembly 10, a prism 20, and a photosensitive component 30. The prism 20 has an inclined surface 201. Incident light 41 is incident on the prism 20 along a first direction and then reflected by the inclined surface 201 into an outgoing light 42 along a second direction. A first preset angle exists between the first and second directions. The prism 20 is a single-piece structure. The lens assembly 10 is disposed at the light incident end 202 of the prism 20, and the photosensitive component 30 is disposed at the light emitting end 203 of the prism 20. By bending the light path and extending the optical path, a higher imaging magnification is achieved.
