[0041] In order to better understand the technical solutions provided by the embodiments of this specification, the technical solutions of the embodiments of this specification are described in detail below through the accompanying drawings and specific embodiments. It should be understood that the embodiments of this specification and the specific features in the embodiments are detailed descriptions of the technical solutions of the embodiments of this specification, rather than limitations on the technical solutions of this specification. In the absence of conflict, the embodiments of this specification and the technical features in the embodiments can be combined with each other.

[0042] In this article, relational terms such as first and second are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply the existence of any such actual relationship or order between these entities or operations. Moreover, the terms "comprise", "include" or any other variants thereof are intended to cover non-exclusive inclusion, so that the process, method, article or equipment comprising a series of elements includes not only those elements, but also other elements not explicitly listed, or also include elements inherent to such process, method, article or equipment. In the absence of further restrictions, the elements defined by the statement "comprising a ..." do not exclude the presence of other identical elements in the process, method, article or equipment comprising the elements. The term "two or more" includes two or more than two cases.

[0043] The present application proposes a camera module 100, which includes but is not limited to a vertical camera module or a horizontal camera module. The camera module 100 can be used in terminal devices such as cameras and mobile phones, and is not limited here.

[0044] The following is combined with Figure 1-10 The camera module 100 according to an embodiment of the present application is described.

[0045] like Figure 1 As shown, the camera module 100 according to an embodiment of the present application includes: a lens assembly 10 , a sensor assembly 20 , a prism assembly 30 and a seal 40 .

[0046] like Figure 2 As shown, the prism assembly 30 has a light incident surface 311 and a light emitting surface 312, the light incident surface 311 and the light emitting surface 312 are located on the same side of the prism assembly 30, and a transition area 313 is connected between the light incident surface 311 and the light emitting surface 312, the light incident surface 311 is set toward the lens assembly 10, and the light emitting surface 312 is set toward the sensor assembly 20.

[0047] It is understood that the prism assembly 30 may include a prism 31, and the prism 31 may be a triangular prism, a quadrangular prism, or a special-shaped prism. In the embodiment in which the prism 31 is a trapezoidal quadrangular prism, for example Figure 1 As shown, the lens assembly 10 and sensor assembly 20 are both located on the same side of the prism assembly 30. With respect to the optical axis of the lens assembly 10, the lens assembly 10 is positioned directly opposite the light-entering surface 311. The light-sensing area of the sensor assembly 20 is positioned opposite the light-emitting surface 312. Thus, light passing through the lens assembly 10 and incident on the light-entering surface 311 enters the prism 31. The light then undergoes at least two reflections from the prism 31 before exiting the light-emitting surface 312 and reaching the sensor assembly 20.

[0048] In this way, the prism 31 can be used to achieve multiple folding of the light path to enhance the light folding effect, thereby facilitating the super-telephoto shooting of the camera module 100.

[0049] At the same time, the lens assembly 10 is arranged opposite to the light incident surface 311, and the sensor assembly 20 is arranged opposite to the light exit surface 312 1. Since the light surface 311 and the light exit surface 312 are located on the same side of the prism assembly 30, that is, the lens assembly 10 and the sensor assembly 20 are both arranged on the same side of the prism 31, so as to reduce the difficulty of arrangement, and make the layout of the lens assembly 10 and the sensor assembly 20 more reasonable, which is conducive to reducing the size of the camera module 100 in the direction of the optical axis. In this way, when the camera module 100 is applied to a mobile phone, it is conducive to reducing the size of the camera module 100 in the plane perpendicular to the thickness of the mobile phone.

[0050] like Figure 3As shown, the seal 40 is disposed between the lens assembly 10 and the sensor assembly 20 and is used to shield the transition area 313 .

[0051] It is understood that the sensor assembly 20 may include, but is not limited to, an image sensor. The sensor assembly 20 is configured to receive the light signal refracted by the prism 31 and form an image. During actual assembly, the distance between the lens assembly 10 and the sensor assembly 20 will be adjusted based on actual conditions. Whether the distance between the lens assembly 10 and the sensor assembly 20 is greater or less, there will still be space between them for assembly.

[0052] Therefore, in the present application, a seal 40 is provided between the lens assembly 10 and the sensor assembly 20 so as to use the seal 40 to seal the assembly space between the lens assembly 10 and the sensor assembly 20, thereby reducing the possibility of debris or dust entering the assembly space.

[0053] Furthermore, the seal 40 can block the transition area 313, thereby reducing the possibility of external light entering the prism assembly 30 through the transition area 313, and reducing the possibility of light at the prism assembly 30 escaping at the transition area 313, thereby improving the imaging effect.

[0054] The side of the seal 40 facing the transition region 313 is coated with a light-shielding layer, which prevents external light from passing through the transition region 313 and entering the prism 31, where it is reflected within the prism 31 to form stray light. In addition, when light is incident on the light-incident surface 311 via the lens assembly 10, it enters the prism 31. The light then undergoes at least two reflections from the prism 31 before being emitted from the light-emitting surface 312 to the sensor assembly 20. During the reflection process within the prism 31, the light may be reflected to the transition region 313 and then irradiated to the seal 40, causing stray light reflection. Therefore, in the present application, a light-shielding layer is provided on the side of the seal 40 facing the transition region 313. The light-shielding layer can absorb stray light and prevent stray light reflection from occurring in the seal 40.

[0055] In some implementations, the light shielding layer may be provided on the sealing member 40 by coating, so as to reduce the difficulty of providing the light shielding layer.

[0056] like Figure 3 As shown, the two opposite ends of the sealing member 40 are respectively a first end 411 and a second end 412. Figure 4 As shown, the first end 411 is fixedly connected to the lens assembly 10, and the second end 412 is fixedly connected to the sensor assembly 20. In this way, the seal 40 is fixed, thereby enhancing the structural stability of the seal 40.

[0057] In some embodiments, there is a first gap 71 between the lens assembly 10 and the plane where the light incident surface 311 is located, the first end 411 is located in the first gap 71, and the first end 411 and the lens assembly 10, or the first gap 71 is filled with adhesive.

[0058] In the prior art, the transition region 313 is coated with a light-shielding layer to prevent stray light from entering. However, because the light-shielding layer is coated, there is a gap (i.e., the first gap 71 in this application) where the transition region 313 borders the lens assembly 10. Furthermore, the lens assembly 10 needs to be fixedly connected to the prism assembly 30, and the coated light-shielding layer cannot be directly glued. Therefore, the first gap 71 cannot be sealed by glue to prevent stray light from entering, nor can it fix the lens assembly 10 and prism assembly 30 to improve the stability of the structure between them.

[0059] The present application arranges the first end 411 in the first gap 71 and fills an adhesive between the lens assembly 10 and the first end 411 to fix the two together. The adhesive can be glue, so that the area where the first end 411 and the lens assembly 10 meet can be sealed and shielded by glue to prevent dust and debris from entering the first gap 71 and reduce the possibility of external light entering the prism assembly 30 through the gap or the light at the prism assembly 30 escaping at the gap, thereby improving the imaging effect.

[0060] Alternatively, an adhesive may be filled in the first gap 71 to directly seal the first gap 71, so as to utilize glue to achieve sealing and light shielding of the first gap 71, thereby preventing dust and debris from entering the first gap 71 and reducing the possibility of external light entering the prism assembly 30 through the gap or light at the prism assembly 30 escaping at the gap, thereby improving the imaging effect.

[0061] At the same time, the first end 411 is clamped between the lens assembly 10 and the plane where the light incident surface 311 is located. The first end 411 can be limited by clamping the lens assembly 10 and the prism assembly 30. On the basis of glue fixation, the structural stability and sealing between the seal 40, the lens assembly 10 and the prism assembly 30 can be further enhanced.

[0062] In some embodiments, a second gap 72 is defined between the sensor assembly 20 and the plane where the light emitting surface 312 is located. The second end 412 is located within the second gap 72 . An adhesive is filled between the second end 412 and the sensor assembly 20 , or the second gap 72 is filled with an adhesive.

[0063] In the prior art, the transition region 313 is coated with a light-shielding layer to prevent stray light from entering. However, because the light-shielding layer is applied, there is a gap (i.e., the second gap 72 in this application) where the transition region 313 borders the sensor assembly 20. Furthermore, the sensor assembly 20 needs to be fixedly connected to the prism assembly 30, and the light-shielding layer cannot be directly glued. Therefore, the first gap 71 cannot be sealed by glue to prevent stray light from entering, nor can it fix the sensor assembly 20 and prism assembly 30 to improve the stability of the structure between them.

[0064] The present application arranges the second end 412 in the second gap 72 and fills an adhesive between the sensor assembly 20 and the second end 412 to fix the two together. The adhesive can be glue, so that the area where the second end 412 and the sensor assembly 20 meet can be sealed and shielded by glue to prevent dust and debris from entering the second gap 72 and reduce the possibility of external light entering the prism assembly 30 through the gap or the light at the prism assembly 30 escaping at the gap, thereby improving the imaging effect.

[0065] Alternatively, an adhesive may be filled in the second gap 72 to directly seal the second gap 72, so as to utilize glue to achieve sealing and light shielding of the second gap 72, thereby preventing dust and debris from entering the second gap 72 and reducing the possibility of external light entering the prism assembly 30 through the gap or light at the prism assembly 30 escaping at the gap, thereby improving the imaging effect.

[0066] At the same time, the second end 412 is clamped between the sensor assembly 20 and the plane where the light incident surface 311 is located. The clamping of the sensor assembly 20 and the prism assembly 30 can be used to limit the second end 412. On the basis of glue fixation, the structural stability and sealing between the seal 40, the sensor assembly 20 and the prism assembly 30 can be further enhanced.

[0067] In this way, the adhesive can be used to fill the gap between the second end 412 and the sensor assembly 20, thereby achieving a fixed connection between the second end 412 and the sensor assembly 20, and further improving the sealing effect of the gap between the second end 412 and the sensor assembly 20 by using the adhesive. At the same time, the adhesive can also play a certain role in blocking light, thereby improving the shading effect.

[0068] In some embodiments, the lens assembly 10 includes a lens, a lens barrel, and a motor 50 . The lens is mounted on the lens barrel, the lens barrel is connected to the motor 50 , and the first end 411 is fixedly connected to the motor 50 .

[0069] It can be understood that a focusing assembly and an anti-shake assembly may be provided in the motor 50. The focusing assembly is used to drive the lens barrel to drive the lens to move in the direction of the lens optical axis to adjust the focal length. The anti-shake assembly is used to drive the lens barrel to drive the lens to move horizontally in a plane perpendicular to the optical axis to realize the anti-shake function of the lens assembly 10. In this way, the imaging stability can be improved.

[0070] And / or the sensor assembly 20 includes a sensor 21 and a motor 50, the sensor 21 is connected to the motor 50, and the second end 412 is fixedly connected to the motor 50. It can be understood that in this embodiment, the lens assembly 10 includes a lens and a lens barrel, the lens is mounted on the lens barrel, and the lens barrel is connected to the motor 50. The motor 50 may be provided with a focusing assembly and an anti-shake assembly. The focusing assembly is used to drive the lens barrel to drive the lens to move in the direction of the lens optical axis to adjust the focal length. The anti-shake assembly is used to drive the lens barrel to drive the lens to move horizontally in a plane perpendicular to the optical axis to achieve the anti-shake function of the lens assembly 10, thereby improving imaging stability.

[0071] In some embodiments, as Figure 2 As shown, the camera module 100 further includes a circuit board 60, which can be a flexible circuit board 60, and the circuit board 60 is electrically connected to the motor 50. In this way, the circuit board 60 can be used to power the focus component and / or the anti-shake component of the motor 50.

[0072] In some embodiments, the bracket 32 is a plastic part and is embedded with a conductive member, which is electrically connected between the circuit board 60 and the motor 50. This prevents leakage of the plastic bracket 32, and because the conductive member is embedded in the bracket 32, the bracket 32 can serve as a carrier for the conductive member, providing a mounting point for the conductive member.

[0073] In some embodiments, as Figure 2 As shown, the sensor assembly 20 includes a sensor 21 and a sensor bracket 22. The sensor bracket 22 is adapted to be mounted on the sensor 21 to protect the sensor 21. The circuit board 60 is disposed above the sensor bracket 22 and is used to cover the sensor bracket 22. In this way, the circuit board 60 and the sensor bracket 22 provide a relatively closed installation space for the sensor 21 to prevent dust and impurities from entering the sensor 21. Furthermore, the placement of the circuit board 60 on the sensor bracket 22 makes the layout of the circuit board 60 and the sensor assembly 20 more compact, thereby reducing the overall volume of the camera module 100 and facilitating a miniaturized design of the camera module 100.

[0074] In some embodiments, as Figure 6 As shown, the sealing member 40 includes a sealing plate, which is in close contact with the transition area 313 .

[0075] It can be understood that the seal 40 can be set as a horizontal plate that is roughly parallel to the transition area 313. In this way, the seal 40 can better fit the transition area 313 to minimize the distance between the seal 40 and the transition area 313, thereby reducing the gap between the two to improve the sealing and shading effects. At the same time, the structural form of the flat plate is relatively simple, which is conducive to reducing the difficulty and cost of setting up the seal 40.

[0076] In some implementations, the tablet may be integrally formed with the bracket 32 , or the tablet may be detachably connected to the bracket 32 , which is not limited herein.

[0077] In some embodiments, the seal 40 includes a sealing portion 41 and a protrusion 42, the sealing portion 41 is connected to the protrusion 42 and is arranged around the protrusion 42, the sealing portion 41 is against the transition area 313, the first end 411 and the second end 412 are both arranged on the sealing portion 41, and the protrusion 42 is arranged to protrude in a direction away from the transition area 313, so that the protrusion 42 is separated from the transition area 313.

[0078] It is understood that because the sealing portion 41 surrounds the protruding portion 42 and abuts against the transition region 313, the distance between the sealing portion 41 and the transition region 313 can be minimized, allowing the first end 411 to extend into the first gap 71 and the second end 412 to extend into the second gap 72. Furthermore, the protruding portion 42 protrudes toward the side away from the transition region 313, thereby utilizing the protruding portion 42 to enhance the structural strength of the sealing member 40.

[0079] In some embodiments, as Figure 2 As shown, the prism assembly 30 includes a prism 31 and a bracket 32 . The prism 31 is installed in the bracket 32 , and the sealing member 40 is detachably connected to the bracket 32 .

[0080] For example, the bracket 32 may be sleeved on the prism 31 , so that the bracket 32 can protect the prism 31 and improve the structural stability of the prism 31 .

[0081] Furthermore, the seal 40 is detachably connected to the bracket 32, for example Figure 6 As shown, the seal 40 is connected to the bracket 32 by snapping. In this way, the connection stability of the seal 40 and the bracket 32 can be enhanced, and the snap connection method is relatively simple, which helps to reduce the difficulty of setting. At the same time, the snap connection facilitates the removal of the seal 40, thereby facilitating the subsequent maintenance and replacement of the seal 40.

[0082] In some embodiments, the seal 40 and the bracket 32 can be connected in a detachable manner by plugging, magnetically engaging, or bolting, which is not limited here.

[0083] In some embodiments, as Figure 6 As shown, the bracket 32 is provided with a first card interface 321, as shown in FIG. Figure 9 and Figure 10 As shown, the sealing member 40 is provided with a first engaging protrusion 43 engaging with the first engaging interface 321 .

[0084] In this way, the seal 40 and the bracket 32 can be connected by snapping together through the snap-fitting of the first snap-fitting protrusion 43 and the first snap-fitting interface 321, thereby enhancing the connection stability of the seal 40 and the bracket 32, and the snap-fitting connection method is relatively simple, which helps to reduce the difficulty of setting up. At the same time, the snap-fitting is conducive to the disassembly of the seal 40, thereby facilitating the later maintenance and replacement of the seal 40.

[0085] In some embodiments, as Figure 6 and Figure 8 As shown, the first card interface 321 is disposed on a first outer side surface 323 of the bracket 32 , and the first outer side surface 323 is parallel to the transition area 313 .

[0086] It is understood that positioning the first card interface 321 on the first outer side surface 323 of the bracket 32, which is parallel to the transition region 313, allows the first card interface 321 to be positioned closer to the transition region 313 and allows the seal 40 to be directly engaged with the bracket 32 within a plane parallel to the transition region 313. This eliminates the need for bending the seal 40, meaning that the seal 40 can be a flat plate. This simplifies the structure of the seal 40 and reduces the difficulty and cost of installing the seal 40.

[0087] In some embodiments, as Figure 6 As shown, there are multiple first engaging interfaces 321 and multiple first engaging protrusions 43, and the multiple first engaging protrusions 43 are arranged in a one-to-one correspondence with the multiple first engaging interfaces 321. That is, at least two sets of first engaging protrusions 43 engaging with the first engaging interfaces 321 are arranged on opposite sides of the seal 40. This facilitates symmetrical arrangement of engaging structures on both sides of the seal 40, thereby improving the engaging stability between the seal 40 and the bracket 32.

[0088] In some embodiments, as Figure 8 As shown, the bracket 32 is provided with at least one second card interface 322, and the second card interface 322 is communicated with the first card interface 321, as shown in FIG. Figure 9 and Figure 10 As shown, the sealing member 40 is further provided with a second clamping protrusion 44 that is clamped and matched with the second clamping interface 322 , and the second clamping protrusion 44 is bent and connected to the first clamping protrusion 43 .

[0089] For example, the second outer side surface 324 of the bracket 32 is provided with a second card interface 322, and the second outer side surface 324 intersects with the first outer side surface 323. In this way, the first card interface 321 and the second card interface 322 distributed on different sides of the bracket 32 can be used to snap into place with the first snap protrusion 43 and the second snap protrusion 44 correspondingly provided on the seal 40 to achieve the snap-fitting fit between the seal 40 and the bracket 32, thereby enhancing the snap-fitting stability between the seal 40 and the bracket 32.

[0090] At the same time, if Figure 8 As shown, the second card interface 322 is connected to the first card interface 321, and as shown in FIG. Figure 9 and Figure 10 As shown, the second engaging protrusion 44 is bent and connected to the first engaging protrusion 43. In this way, the engaging engagement between the first engaging protrusion 43 and the first engaging interface 321 is linked to the engaging engagement between the second engaging protrusion 44 and the second engaging interface 322. Compared to a single engaging engagement, the double engaging engagement of the present application can further enhance the engaging stability between the sealing member 40 and the bracket 32.

[0091] In some embodiments, the seal 40 is a metal member.

[0092] In this way, the structural strength of the sealing member 40 is greater, which is beneficial to enhancing the structural stability of the sealing member 40. In addition, when the sealing member 40 is a metal member, the size, especially the thickness, is smaller, which is beneficial to assembly.

[0093] In some embodiments, the lens assembly 10 includes multiple groups of lenses spaced apart in the direction of the optical axis, and the focusing assembly uses a moving single group of lenses to achieve focusing, and relatively moves the entire lens assembly 10 to focus, thereby reducing the displacement of the motor 50 during the focusing process, reducing the motor reliability risk and the impact on optical performance caused by the large stroke. At the same time, the present application can use the lens assembly 10 for optical image stabilization, which can reduce the anti-shake stroke, reduce the size of the motor 50, and reduce the reliability risk of the motor 50.

[0094] For example, the lens assembly 10 of the present application includes two groups of lenses, which are spaced apart in the direction of the optical axis. In this way, the arrangement of the two groups of lenses and the prism assembly 30 can be used to achieve a large aperture and telephoto macro effect.
