Of course, in the implementation process, as shown in fig. 4, the bracket 7 may be omitted to reduce the assembly steps, a supporting structure 41 is designed at the edge of the lens 4, the lens 4 is directly attached or fixed on the circuit substrate 1 by means of the supporting structure 41 in a snap-fit manner, and the optical filter 3 is fixed on the supporting structure 41 of the lens 4 and is spaced from the central main body region of the lens 4 by a certain distance.
Next, a light emitting section will be described.
The light emitting portion in the imaging module provided in this embodiment includes a light emitting element 5 and a light guide structure 6. The light-emitting surface of the light-emitting element 5 faces the light-guiding structure 6, so that light can enter the light-guiding structure 6 to be guided, and the emitted light can be overlapped with the path of the light received by the camera shooting part, so that the light-emitting element 5 and the photosensitive element 2 can share the transparent hole when the camera shooting module is installed on the electronic device.
The light emitting element 5 provided in this embodiment may be fixed to the wiring substrate 1, for example, in the edge region, or the light emitting element 5 may be fixed to the edge region of the front surface of the lens 4, the front surface being a surface of the lens 4 facing the transparent hole of the electronic device to which the lens is mounted, that is, a surface receiving light. The light guide structure 6 of the present embodiment may be fixed to the outer surface of the image pickup unit integrally with the image pickup unit, or may be fixed to the inner wall of the electronic device to which the image pickup module is attached, and may be set in accordance with the attachment position of the image pickup unit, which will be described below.
First, the light guide structure 6 is fixed to the inner wall of the electronic device on which the camera module is mounted.
As shown in fig. 1, the light guide structure includes a reflective structure 61 and a light guide part 62. When the camera module is installed in the electronic device, the light-transmitting area of the light guide part 62 faces the front central area of the lens 4, specifically, the light guide part or the light guide cover may be of a structure such as a light guide plate or a light guide cover, and specifically, the light guide part 62 may be fixed inside or inside the electronic device by fitting or engaging, when the electronic device includes the screen 101, the light guide part 62 is located below the screen 101, and the outer surface of the screen 101 may further be provided with a protective layer 102 (e.g., a glass layer. The reflection structure 61 is fixed at a position corresponding to the light guide portion 62, and may be a prism, a metal sheet, or the like. The light emitting surface of the light emitting element 5 faces the reflective structure 61, and the reflective structure 61 is disposed at a position and at an angle that can reflect the light emitted by the light emitting element 5 to the side of the light guide portion 62. The reflective structure 61 reflects the light emitted from the light emitting element 5 into the light guide part 62, and is reflected inside the light guide part 62 and emitted from the light transmitting region of the light guide part 62.
The light emitting element 5 may be fixed on the circuit substrate 1, and located outside the region where the lens 4 or the bracket 7 is mounted, and the light emitting element 5 and the circuit substrate 1 implement electrical signal connection, specifically, the connection may be implemented by attaching a conductive material, or may be implemented by bonding, which is not limited herein.
The edge regions of the upper and lower surfaces of the light guide part 62 are coated with the light blocking layer 64 (thick line region in the figure), and the central light-transmitting region of the light guide part and the side or end surface region for receiving light are not coated with the light blocking layer 64 and are light-transmitting, so that the interference of stray light during imaging of the photosensitive element 2 is avoided. The light blocking layer 64 may be a black ink layer or a metal layer, and the light-transmitting area of the central light-blocking layer of the light guide part 62 may be determined according to the size of the light-sensing area of the light-sensing element 3. The light emitted from the light emitting element 5 enters from the side edge 621 of the light guide unit 62, is reflected by the light blocking layer 64 inside the light guide unit 62, and then exits from the light transmitting region of the light guide unit 62 without the light blocking layer in the center.
For example, as shown in fig. 1, the light guide part 62 is a light guide plate, the reflective structure 61 is disposed in an area opposite to a side of the light guide plate and located above the light emitting element 5, when the light emitting element 5 emits light, light is emitted to the reflective surface of the reflective structure 61 as shown by an arrow in the figure, and then reflected to the side of the light guide plate to enter the light guide plate, and the light is reflected inside the light guide plate and then emitted from a light-transmitting area without a light blocking layer in the center of the light guide plate, so as to realize functions of a breathing lamp, a warning lamp, and the like.
Of course, when the light-emitting element 5 is fixed on the lens or the holder, the light guide structure 6 may also be fixed in the electronic device mounted with the camera module as shown in fig. 1, and it is only necessary to ensure that the positions of the light-emitting element 5, the reflection structure 61 and the light guide portion 62 are matched, and thus, the restriction on the mounting positions of the light-emitting element 5 and the light guide portion 62 by adopting the arrangement mode of the reflection structure is small, and the applicable device environment is wider.
Second, the light guide structure 6 is fixed to the outer surface of the image pickup section.
As shown in fig. 2 to 5, the light guide structure 6 may be fixed on the circuit substrate 1, or may be fixed on the lens 4 or the holder 7. The light guide structure 6 includes: the light incident part 63 covers the light emitting element 5, so that the light emitted by the light emitting element 5 can enter the light guide structure 6 from the light incident part 63. The light guide 62 at least partially covers the lens 4, and has a central light-transmitting area fixed opposite to the front central area of the lens 4, so as to provide light guiding function and protect the lens 4. The light emitted from the light emitting element 5 enters the light guide part 62 from the light incident part 63, is reflected inside the light guide part 62, and is emitted from the central light transmitting region of the light guide part 62.
Similarly, the edge regions of the inner and outer surfaces of the light guide part 62 may be coated with the light blocking layer 64 (thick line region in the figure), and the central light-transmitting region of the light guide part 62 and the light incident part 63 are not coated with the light blocking layer 64 and are light-transmitting, so as to avoid the interference of stray light when the photosensitive element 2 forms images. The light blocking layer 64 may be a black ink layer or a metal layer, and the light-transmitting area of the central light-blocking layer of the light guide part 62 may be determined according to the size of the light-sensing area of the light-sensing element 3. The light emitted from the light emitting element 5 enters from the light entrance portion 63, is reflected by the light blocking layer 64 inside the light guide portion 62, and is emitted from the light transmitting region of the light guide portion 62 without the light blocking layer in the center.
For example, as shown in fig. 2 to 3, the light emitting element 5 is fixed on the edge region of the circuit substrate 1, and is electrically connected to the circuit substrate 1, specifically, the connection may be realized by attaching a conductive material, or may be realized by bonding, which is not limited herein. The light guide structure 6 is a light guide cover, the light incident portion 63 is an end surface of the light guide cover or a region covering the light emitting element 5 on the end surface of the light guide cover, and the light guide portion 62 is a portion other than the light incident portion 63. The central light-transmitting area of the light guide cover faces the front surface of the lens 4 and is fixed on the circuit substrate 1, and may be fixed by adhesion or clamping. Photosensitive element 2, light filter 3 and camera lens 4 are all placed in the space that light guide cover and circuit substrate 1 enclose in, and the light guide cover not only provides the leaded light effect, still plays protection and waterproof vapour dirt-proof effect to the portion of making a video recording.
In a specific implementation process, as shown in fig. 2, a groove may be formed in the circuit substrate 1, the light emitting element 5 is placed in the groove, the end surface of the light guide cover is attached to the circuit substrate 1, the groove is covered by the end surface, and light emitted by the light emitting element 5 enters the light guide cover from the end surface covering the groove. As shown in fig. 3, a groove may be formed in the end surface of the light guide cover, the light emitting element 5 is fixed to the circuit board 1, the end surface of the light guide cover is attached to the circuit board 1, the groove covers the light emitting element 5, and light emitted by the light emitting element 5 enters the light guide cover from the periphery of the groove. When the light emitting element 5 emits light, as indicated by an arrow in the figure, the emitted light enters the light guide cover from the light entrance portion 63, is reflected by the light blocking layer 64 inside the light guide cover, and then is emitted from the light transmission region without the light blocking layer in the center of the light guide cover, so that functions of a breathing lamp, a warning lamp and the like which need to emit light are realized.
For another example, as shown in fig. 4 to 5, the light emitting element 5 may be fixed to the edge region of the front surface of the lens 1 by a fixing method such as adhesion or engagement. The light guide structure 6 is adhered, clamped or fixed on the lens 4 by adopting a thread structure, and the light transmission area of the light guide structure is opposite to the front of the lens 4. The light guide structure 6 may be a light guide cover or a light guide plate, the light incident portion 63 is a region where the light guide structure 6 covers the light emitting element 5, and the light guide portion 62 is a portion other than the light incident portion 63. The light guide structure 6 not only provides a light guide function, but also plays a role in protecting the lens 4 of the camera shooting part and preventing water, vapor and dust.
In the case where the light emitting element 5 is fixed to the surface of the lens 4 or the holder 7, the light emitting element 5 is not directly in contact with the circuit board 1, and thus, electrical signal connection is achieved. As shown in fig. 4, a solid line 401(LDS line) prepared by a laser direct structuring technique may be provided on the surface of the lens 4 and/or the holder 7. The light-emitting element 5 is attached to the three-dimensional circuit 401 by using a conductive material to realize electrical signal connection, or the light-emitting element 5 is bonded with the three-dimensional circuit to realize electrical signal connection. The three-dimensional circuit 401 is connected to the circuit substrate 1 by a conductive material (such as solder) or by bonding, so as to realize electrical signal connection between the light emitting element 5 and the circuit substrate 1.
As shown in fig. 5, a flexible plate 501 may be disposed on the surface of the lens 4 and/or the support 7. The light emitting element 5 is attached to the flexible board 501 by using a conductive material to realize electrical signal connection, or the light emitting element 5 and the flexible board 501 are bonded to realize electrical signal connection. The flexible board 501 is connected to the circuit substrate 1 by a conductive material (such as solder) or by bonding, so as to realize the electrical signal connection between the light emitting element 5 and the circuit substrate 1. The flexible board 501 and the circuit substrate 1 may be designed as an integral structure, and the flexible board 501 on the side is bent and attached along the bracket 7 and/or the lens edge and extends to the position of the light emitting element 5. The two sides of the circuit substrate 1 can also be flexible plates, one side of the flexible plate is connected with the light-emitting element 5 after being bent, and the other side of the flexible plate is connected with the electronic equipment provided with the module.
By arranging the light-emitting element 5 to be fixed on the front edge of the lens 4, the distance from the light of the light-emitting element 5 to the outside of the camera module can be reduced, and the light emission amount is increased. The size of the light guiding structure 6 can be reduced, reducing the weight and overall size of the module.
Of course, in the specific implementation process, the light emitted by the light emitting element 5 is guided out through the light guiding structure 6, and the implementation manner of overlapping the guiding light path and the path of the light received by the image capturing part is not limited to the above two, and the light can be guided by providing a light barrier which surrounds the light guiding structure, which is not limited herein, and is not listed.
In the specific implementation process, in order to avoid the influence on the shooting function when the light-emitting element 5 emits light, the light-emitting element 5 can be set to be in a non-light-emitting state when the photosensitive element 2 is in a photosensitive transition state; when the light emitting element 5 is in a light emitting state, the light sensing element 2 is in a non-light sensing state. The specific state switching control may be realized by a main board or a controller of the electronic device connected to the circuit substrate 1.

The light emitting element 5 in the electronic device may be a light source implementing a breathing light function. Through the built-in module 601 of making a video recording that has light emitting component 5 and light sensing component 2 concurrently that one provided of built-in embodiment, this electronic equipment's breathing lamp function or other need light emitting function can with make a video recording the same transparent hole 602 of function sharing, electronic equipment's display surface only need set up a transparent hole 602 and have the light of the light emitting function such as the light collection hole of the function of making a video recording and breathing lamp promptly and jet out the hole function. It can be seen that this application can be better compromise function demands such as breathing lamp and screen and account for the demand, need not sacrifice user function demand and must not additionally increase the basis that the module size made a video recording and can effectively guarantee that the screen accounts for the ratio.
