Description

Technical Field

[0001] This application relates to the field of camera technology, and more particularly to a camera module. Background Technology

[0002] In the consumer electronics field, especially in the smartphone sector, miniaturized and lightweight camera modules are an indispensable component, and currently, portable devices are equipped with at least one camera module. To meet increasingly diverse market demands, the requirements for camera modules are becoming more sophisticated.

[0003] Telephoto camera modules employing irregularly shaped prisms can achieve multiple folds in the optical path through these prisms, enhancing the folding effect and enabling ultra-telephoto shooting. Furthermore, by positioning the lens assembly and sensor assembly on the light-incident surface of the irregularly shaped prism along the thickness of the phone, it is beneficial to reduce the size of the camera module in a plane perpendicular to the phone's thickness.

[0004] However, the lens assembly and sensor assembly cannot be tightly fitted together, leaving an assembly space. External light can easily enter the prism assembly through this assembly space, thus affecting the imaging effect. Utility Model Content

[0007] According to the camera module of this application embodiment, by setting a seal between the lens assembly and the sensor assembly, the assembly space between the lens assembly and the sensor assembly is sealed by the seal, reducing the possibility of debris or dust entering the assembly space. At the same time, the seal can also block the transition area between the light-incoming surface and the light-outcoming surface, thereby reducing the possibility of external light entering the prism assembly from the transition area or the light at the prism assembly scattering at the transition area, thereby improving the imaging effect.

[0014] According to some embodiments of the camera module of this application, the sealing element is a metal component.

[0015] According to some embodiments of the camera module of this application, the sealing member has a light-shielding layer on the side facing the transition region.

[0016] According to some embodiments of the camera module of this application, the prism assembly includes a bracket, and the seal is detachably connected to the bracket.

[0041] To better understand the technical solutions provided in the embodiments of this specification, the technical solutions of the embodiments of this specification will be described in detail below with reference to 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 document, relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, without necessarily requiring or implying any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element. The term "two or more" includes two or more cases.

[0043] This 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 thereto.

[0044] The following is in conjunction with the appendix Figure 1-10 This application describes a camera module 100 according to an embodiment of the present application.

[0045] like Figure 1 As shown, the camera module 100 according to an embodiment of this 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 an incident light surface 311 and an exit light surface 312. The incident light surface 311 and the exit light surface 312 are located on the same side of the prism assembly 30, and a transition region 313 connects the incident light surface 311 and the exit light surface 312. The incident light surface 311 is disposed towards the lens assembly 10, and the exit light surface 312 is disposed towards the sensor assembly 20.

[0047] It is understood that the prism assembly 30 may include a prism 31, which can be a triangular prism, a square prism, or an irregularly shaped prism. For example, in the implementation where the prism 31 is a trapezoidal square prism... Figure 1 As shown, the lens assembly 10 and the sensor assembly 20 are both located on the same side of the prism assembly 30, and the lens assembly 10 is directly opposite the light-incident surface 311 in the direction of the optical axis of the lens assembly 10; the photosensitive area of ​​the sensor assembly 20 is opposite to the light-emitting surface 312. In this way, after light enters the light-incident surface 311 through the lens assembly 10, it enters the prism 31, and then the light is reflected at least twice by the prism 31 and exits from the light-emitting surface 312 to the sensor assembly 20.

[0048] In this way, the prism 31 can be used to achieve multiple folds in the optical path to enhance the light folding effect, which in turn facilitates the ultra-telephoto shooting of the camera module 100.

[0049] Meanwhile, the lens assembly 10 is positioned opposite to the light-incident surface 311, and the sensor assembly 20 is positioned opposite to the light-exiting surface 312. Since the light-incident surface 311 and the light-exiting 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 positioned on the same side of the prism 31, it is easier to reduce the difficulty of arrangement and make the layout of the lens assembly 10 and the sensor assembly 20 more reasonable. This is beneficial to reduce the size of the camera module 100 in the direction of the optical axis. Thus, when the camera module 100 is applied to a mobile phone, it is beneficial to reduce 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 block the transition area 313.

[0051] It is understood that the sensor assembly 20 may include, but is not limited to, an image sensor, which is used to receive light signals refracted by the prism 31 and form an image. In actual assembly, the distance between the lens assembly 10 and the sensor assembly 20 will be adjusted according to the actual situation, and there will be assembly space between the lens assembly 10 and the sensor assembly 20 whether the distance between them is large or small.

[0052] Therefore, in this application, a seal 40 is provided between the lens assembly 10 and the sensor assembly 20 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 region 313, thereby reducing the possibility of external light entering the prism assembly 30 through the transition region 313, and reducing the possibility of light at the prism assembly 30 escaping at the transition region 313, thereby improving the imaging effect.

[0054] A light-shielding layer is coated on the side of the seal 40 facing the transition region 313 to prevent external light from passing through the transition region 313 and entering the prism 31, where it is reflected to form stray light. Furthermore, when light enters the light-incident surface 311 via the lens assembly 10, it enters the prism 31. The light then undergoes at least two reflections within the prism 31 before exiting the light-out surface 312 and reaching the sensor assembly 20. During the reflection process within the prism 31, the light may reflect back to the transition region 313 and then onto the seal 40, causing stray light reflection. Therefore, in this application, a light-shielding layer is provided on the side of the seal 40 facing the transition region 313. This light-shielding layer absorbs stray light to prevent stray light reflection from occurring on the seal 40.

[0055] In some implementations, the light-shielding layer can be applied to the seal 40 by means of a coating, which reduces the difficulty of setting the light-shielding layer.

[0056] like Figure 3 As shown, the two opposite ends of the seal 40 are the first end 411 and the second end 412, respectively. 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. This secures the seal 40, thereby enhancing its structural stability.

[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, since the light-shielding layer is coated, there will be a gap (i.e., the first gap 71 in this application) at the junction of the transition region 313 and 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 the prism assembly 30 to improve the stability of their structure.

[0059] This application fixes the first end 411 within the first gap 71 and fills the space between the lens assembly 10 and the first end 411 with an adhesive. 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 from light by the glue. This prevents dust and debris from entering the first gap 71 and reduces the possibility of external light entering the prism assembly 30 through the gap or light from the prism assembly 30 escaping at the gap, thereby improving the imaging effect.

[0060] Alternatively, adhesive can be filled into the first gap 71 to directly seal the first gap 71, so as to use glue to seal and block light from the first gap 71, 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.

[0061] Meanwhile, the first end 411 is clamped between the plane where the lens assembly 10 and the light-incident surface 311 are located. The clamping of the lens assembly 10 and the prism assembly 30 can be used to limit the position of the first end 411. Based on the glue fixation, the structural stability and sealing performance among the sealing member 40, the lens assembly 10 and the prism assembly 30 can be further enhanced.

[0062] In some embodiments, a second gap 72 is provided between the sensor assembly 20 and the plane containing the light-emitting surface 312, the second end 412 is located within the second gap 72, and 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, since the light-shielding layer is coated, there will be a gap (i.e., the second gap 72 in this application) at the junction of the transition region 313 and the sensor assembly 20. Furthermore, the sensor assembly 20 needs to be fixedly connected to the prism assembly 30, and the coated light-shielding layer cannot be directly applied with adhesive. Therefore, the first gap 71 cannot be sealed with adhesive to prevent stray light from entering, nor can it fix the sensor assembly 20 and the prism assembly 30 to improve the stability of their structure.

[0064] This application fixes the second end 412 within the second gap 72 by filling the space between the sensor assembly 20 and the second end 412 with an adhesive. 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 from light by the glue. This prevents dust and debris from entering the second gap 72 and reduces the possibility of external light entering the prism assembly 30 through the gap or light from the prism assembly 30 escaping at the gap, thereby improving the imaging effect.

[0065] Alternatively, adhesive can be filled into the second gap 72 to directly seal the second gap 72, thereby using glue to seal and block light from the second gap 72, 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 from the prism assembly 30 escaping at the gap, thus improving the imaging effect.

[0066] Meanwhile, the second end 412 is clamped between the plane containing the sensor assembly 20 and the light-incident surface 311. The clamping of the sensor assembly 20 and the prism assembly 30 can limit the position of the second end 412. Based on the glue fixation, the structural stability and sealing performance among the sealing element 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, while the adhesive further improves the sealing effect of the gap between the second end 412 and the sensor assembly 20. At the same time, the adhesive can also play a certain role in blocking light, thereby improving the light-blocking 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 is understandable that the motor 50 may contain a focusing component and an image stabilization component. The focusing component is used to drive the lens barrel to move the lens in the direction of the lens optical axis to achieve focal length adjustment. The image stabilization component is used to drive the lens barrel to move the lens horizontally in a plane perpendicular to the optical axis to achieve the image stabilization function of the lens assembly 10. In this way, the image stability can be improved.

[0070] 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 is understood that in this embodiment, the lens assembly 10 includes a lens element and a lens barrel. The lens element is mounted in the lens barrel, which is connected to the motor 50. The motor 50 may contain a focusing assembly and an image stabilization assembly. The focusing assembly drives the lens barrel to move the lens element in the direction of the lens's optical axis to adjust the focal length. The image stabilization assembly drives the lens barrel to move the lens element horizontally in a plane perpendicular to the optical axis to achieve image stabilization of the lens assembly 10. This improves image stability.

[0071] In some embodiments, such as Figure 2 As shown, the camera module 100 also includes a circuit board 60, which can be a flexible circuit board, and is electrically connected to the motor 50. In this way, the circuit board 60 can be used to power the focusing components and / or image stabilization components of the motor 50.

[0072] In some embodiments, the bracket 32 ​​is a plastic part and has an embedded conductive element, which is electrically connected between the circuit board 60 and the motor 50. This prevents leakage problems as the bracket 32 ​​is a plastic part, and because the conductive element is embedded in the bracket 32, the bracket 32 ​​can serve as a carrier for the conductive element, providing mounting points for it.

[0073] In some embodiments, such 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 fitted onto the sensor 21 to protect it. 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 can provide a relatively sealed installation space for the sensor 21 to prevent dust or impurities from entering the sensor 21. At the same time, the circuit board 60 is disposed on the sensor bracket 22, making the layout of the circuit board 60 and the sensor assembly 20 more compact, thereby helping to reduce the overall size of the camera module 100 and facilitating the miniaturization design of the camera module 100.

[0074] In some embodiments, such as Figure 6 As shown, the seal 40 includes a sealing plate that is fitted and connected to the transition area 313.

[0075] Understandably, the seal 40 can be set as a horizontal plate that is roughly parallel to the transition area 313. This allows the seal 40 to fit better with the transition area 313, minimizing the distance between the seal 40 and the transition area 313, thereby reducing the gap between them and improving the sealing and light-blocking effects. At the same time, the flat plate structure is relatively simple, which helps to reduce the difficulty and cost of setting the seal 40.

[0076] In some implementations, the tablet can be integrally formed with the bracket 32, or the tablet can be detachably connected to the bracket 32; no limitation is made here.

[0077] In some embodiments, the seal 40 includes a sealing portion 41 and a protrusion 42. The sealing portion 41 is connected to and surrounds the protrusion 42. The sealing portion 41 abuts against the transition region 313. A first end 411 and a second end 412 are both provided on the sealing portion 41. The protrusion 42 protrudes in a direction away from the transition region 313, so that the protrusion 42 is spaced apart from the transition region 313.

[0078] Understandably, since the sealing portion 41 is arranged around the protrusion 42 and abuts against the transition region 313, the distance between the sealing portion 41 and the transition region 313 can be minimized, and the first end 411 can extend into the first gap 71, and the second end 412 can extend into the second gap 72. At the same time, the protrusion 42 protrudes towards the side away from the transition region 313, which facilitates the use of the protrusion 42 to enhance the structural strength of the seal 40.

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

[0080] For example, the bracket 32 ​​can be fitted onto 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 snapped into the bracket 32. This enhances the connection stability between the seal 40 and the bracket 32, and the snap-fit ​​connection method is relatively simple, which helps to reduce the difficulty of installation. At the same time, the snap-fit ​​connection facilitates the disassembly of the seal 40, thereby facilitating the later maintenance and replacement of the seal 40.

[0082] In some embodiments, the seal 40 and the bracket 32 ​​can be detachably connected by plugging, magnetic attraction, or bolting, etc., which is not limited here.

[0083] In some embodiments, such as Figure 6 As shown, the bracket 32 ​​is provided with a first card interface 321, such as Figure 9 and Figure 10 As shown, the sealing element 40 is provided with a first snap-fit ​​protrusion 43 that snaps into the first snap-fit ​​interface 321.

[0084] In this way, the seal 40 and the bracket 32 ​​can be connected by the snap-fit ​​between the first snap-fit ​​protrusion 43 and the first snap-fit ​​interface 321, thereby enhancing the connection stability of the seal 40 and the bracket 32. The snap-fit ​​connection method is relatively simple and helps to reduce the difficulty of setting. At the same time, the snap-fit ​​connection facilitates the disassembly of the seal 40, thereby facilitating the later maintenance and replacement of the seal 40.

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

[0086] Understandably, positioning the first card interface 321 on the first outer side 323 parallel to the transition area 313 of the bracket 32 ​​allows the first card interface 321 to be positioned closer to the transition area 313, and enables the seal 40 to directly engage with the bracket 32 ​​within the plane parallel to the transition area 313. This eliminates the need for bending of the seal 40, allowing it to be a flat structure, thus simplifying its design and reducing installation difficulty and cost.

[0087] In some embodiments, such as Figure 6 As shown, multiple first card interfaces 321 and multiple first card engagement protrusions 43 are provided, with each protrusion corresponding to a different first card interface 321. That is, at least two sets of first card engagement protrusions 43 and first card interfaces 321 are positioned opposite each other on both sides of the sealing member 40 for engagement. This facilitates symmetrically arranged engagement structures on both sides of the sealing member 40, thereby improving the engagement stability between the sealing member 40 and the bracket 32.

[0088] In some embodiments, such as Figure 8 As shown, the bracket 32 ​​is provided with at least one second card interface 322, which is connected to the first card interface 321, as follows. Figure 9 and Figure 10 As shown, the sealing element 40 is also provided with a second snap-fit ​​protrusion 44 that snaps into the second snap-fit ​​interface 322, and the second snap-fit ​​protrusion 44 is bent and connected to the first snap-fit ​​protrusion 43.

[0089] For example, the second outer side 324 of the bracket 32 ​​is provided with a second locking interface 322, which intersects with the first outer side 323. In this way, the locking interfaces 321 and 322 distributed on different sides of the bracket 32 ​​can be used to lock the sealing member 40 and the bracket 32 ​​by engaging with the first locking protrusion 43 and the second locking protrusion 44 respectively provided on the sealing member 40, thereby enhancing the locking stability of the sealing member 40 and the bracket 32.

[0090] At the same time, such as Figure 8 As shown, the second card interface 322 is connected to the first card interface 321, and as... Figure 9 and Figure 10 As shown, the second snap-fit ​​protrusion 44 is bent and connected to the first snap-fit ​​protrusion 43. In this way, the snap-fit ​​engagement of the first snap-fit ​​protrusion 43 and the first snap-fit ​​interface 321 is associated with the snap-fit ​​engagement of the second snap-fit ​​protrusion 44 and the second snap-fit ​​interface 322. Compared with a single snap-fit ​​engagement, the dual snap-fit ​​engagement of this application can further enhance the snap-fit ​​stability between the seal 40 and the bracket 32.

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

[0092] This results in greater structural strength for the seal 40, enhancing its structural stability. Furthermore, the seal 40's smaller dimensions, particularly its thickness, facilitate assembly when made of metal.

[0093] In some embodiments, the lens assembly 10 includes multiple groups of lenses spaced apart in the direction of the optical axis. The focusing assembly uses a single group of lenses to achieve focusing. The focusing is achieved by moving the entire lens assembly 10, which reduces the displacement of the motor 50 during focusing, thereby reducing the motor reliability risk and the impact on optical performance caused by the large stroke. At the same time, this application can use the lens assembly 10 for optical image stabilization, which can reduce the image stabilization 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 this 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 achieve large aperture and telephoto macro effects.
