detailed description

The technical solutions in the embodiments of the present application are clearly and completely described in the following with reference to the drawings in the embodiments of the present application. It is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments of the present application without departing from the inventive scope are the scope of the present application.

FIG. 1 shows a terminal device 100 according to an embodiment of the present application. The terminal device 100 includes, but is not limited to, an electronic terminal such as a mobile phone or a tablet computer. The terminal device 100 includes a housing, and an image pickup assembly, a power supply device, a radio frequency device, an audio/video device (such as a display screen), and the like installed in the housing.

2 and 3 show the camera assembly 10 in the terminal device 100. In this embodiment, the camera component 10 can be a front camera component of the terminal device 100, which is used for implementing a self-timer, a video call function, and the like, and can also be a rear camera component for functions such as photographing and video recording.

The camera assembly 10 can include a camera assembly and a flash unit disposed adjacent to each other. The camera assembly can include a camera 16 and a camera lens 12. The camera lens 12 is used to transmit light entering the camera 16. The flash unit is configured to fill light when the camera assembly captures an image. The flash unit can include a flash 18 and a flash lens 14. The flash lens 14 is used to transmit light from the flash lamp 18. The camera lens 12 is provided with a light blocking layer to block the light emitted by the flash lamp 18 from entering the camera 16 .

Specifically, the light blocking layer may include a light blocking ink layer. The light blocking ink layer is formed by spraying a light blocking ink. The light blocking ink has the characteristics of preventing light from entering, and the cost is low, the light blocking effect is good, and the use is mature. Of course, the light blocking layer may also be other functional layers capable of preventing light from entering, and may not be limited to being formed by spraying.

The camera lens 12 is aligned with the camera 16 and the flash lens 14 is aligned with the flash 18. The position of the light blocking layer on the camera lens 12 can be determined according to actual product design requirements to ensure that the camera lens 12 can transmit light, and is sufficient to block the light emitted by the flash lamp 18 from entering the camera 16. The surface covered by the light blocking layer is the surface that the light emitted by the flash lamp 18 can reach.

For example, the light blocking layer may be provided on a circumferential surface of the camera lens 12 (ie, a surface whose direction is substantially perpendicular to the axial direction of the camera lens 12). The light blocking layer may cover the entire circumferential surface or may cover only a part of the circumferential surface.

For another example, the light blocking layer may be provided on the light incident end surface of the camera lens 12 (ie, the surface direction is along the surface of the camera lens 12 in the axial direction). In this case, the light blocking layer covers only part of the light incident end face to avoid completely blocking natural light from entering.

When the camera assembly 10 is in operation, light from the flash lamp 18 will be transmitted through the flash lens 14 to the surface of the object being photographed. At the same time, since the flash unit is designed adjacent to the camera assembly, the light emitted by the flash 18 can also directly enter the camera lens 12, and then enter the camera 16, affecting the imaging quality of the camera 16. Since the light blocking layer is present on the camera lens 12, the light emitted by the flash lamp 18 is blocked by the light blocking layer and cannot enter the camera lens 12. The camera 16 does not receive the light emitted by the flash 18, and the imaging of the camera 16 does not occur. It is affected by the light from the flash 18. Thus, the solution of the present embodiment can avoid the crosstalk of the flashlight 18 to the camera 16 and ensure the imaging quality of the camera 16.

Further, as shown in FIGS. 2 and 3, the camera assembly 10 may further include a transparent cover plate 13. A first through hole 131 and a second through hole 132 are defined in the transparent cover 13 . The camera lens 12 is received in the first through hole 131, and the flash lens 14 is received in the second through hole 132. The transparent cover 13 functions to house and hold the camera lens 12 and the flash lens 14. The transparent cover 13 is a transparent material, and the design can increase the appearance and the user experience.

In this embodiment, since the transparent cover 13 is a light-transmitting material, the light emitted by the flash lamp 18 passes through the inner wall of the second through-hole 132 and enters the transparent cover 13 after passing through the flash lens 14, and then passes through the first The inner wall of a through hole 131 is transmitted to the circumferential surface of the camera lens 12 in the first through hole 131. At this time, the light blocking layer may be added to the circumferential surface to block the light of the flash lamp 18 from entering the camera lens 12.

In addition, the intensity, optical and processing requirements of the camera lens 12 and the flash lens 14 are relatively high compared to the transparent cover 13. For example, the transparent cover 13 may be made of acrylic material, and the camera lens 12 may be made of sapphire material. Therefore, the transparent cover 13 which is independent of the camera lens 12 and the flash lens 14 and is not integrated into one body can be designed and processed in a key position, thereby saving cost. Of course, the transparent cover 13 and the camera lens 12 and the flash lens 14 can also have the same strength, optical parameters and processing techniques.

Further, as shown in FIGS. 2 and 3, the camera assembly 10 may further include a bezel 15. The frame 15 encloses the camera lens 12 and the flash lens 14 in the transparent cover 13 and the transparent cover 13 therein. The bezel 15 serves as a decoration and retention. The bezel 15 can be made of a metal material to enhance the texture and achieve grounding. Of course, the bezel 15 can also be made of a non-metallic material.

Further, as shown in FIGS. 2 and 3, the camera assembly 10 may further include a housing 11. The camera 16 and the flash 18 are both disposed in the housing 11 , and the frame 15 and the transparent cover 13 are both mounted on the housing 11 . An opening 111 and an opening 112 are respectively provided in the housing 11 at positions corresponding to the camera 16 and the flasher 18. The first through hole 131 is aligned with the opening 111 of the corresponding camera 16, and the second through hole 132 is aligned with the opening 112 of the corresponding flash lamp 18.

Specifically, the housing 11 is a bearing member for mounting the frame 15, the transparent cover 13, the camera lens 12, and the flash lens 14. The housing 11 can be assembled as a separate component into the housing of the terminal device 100. This discrete design facilitates repair and replacement. The housing 11 can also be part of the housing of the terminal device 100.

As shown in FIG. 2 and FIG. 3, the transparent cover 13 is covered on the housing 11, and the first through hole 131 and the second through hole 132 on the transparent cover 13 are respectively aligned with the opening 111 and the opening 112, so that The camera lens 12 in the first through hole 131 is aligned with the flash lens 18 in the camera 16 and the second through hole 132. Thus, natural light can enter the camera 16 through the camera lens 12 and opening 111, and the light from the flash 18 passes through the opening 112 and exits through the flash lens 14.

Further, in the present example, as shown in FIG. 3, the opening 112 of the housing 11 corresponding to the flash lamp 18 may be a stepped hole. The flash lens 14 includes a light incident portion 142 and a light exit portion 141. The light incident portion 142 is disposed on the step of the stepped hole and is engaged with the edge of the second through hole 132, and the light incident portion 142 and the flash unit 18 are included. alignment. The light exit portion 141 is bored in the second through hole 132. The radial dimension of the light incident portion 142 is larger than the radial dimension of the light exit portion 141 (also larger than the inner diameter of the second through hole 132). When the light exit portion 141 is bored in the second through hole 132, the light incident portion 142 is held at The flash lens 14 is fixed between the transparent cover 13 and the housing 11. The light of the flash lamp 18 is emitted through the light exit portion 141 that is disposed in the second through hole 132. The stepped hole and the flash lens 14 including the associated light incident portion 142 and the light exit portion 141 are designed to stably place the flash lens 14 on the casing 11 and securely hold it. In other embodiments, the opening 112 may not necessarily be a stepped hole, but rather a conventional through hole. Accordingly, the flash lens 14 can have a uniform radial dimension as the camera lens 12, without the need for a "head" shape. At this time, the flash lens 14 is entirely housed in the second through hole 132.

Further, in this example, as shown in FIG. 3, the first through hole 131 may be a stepped hole. The camera lens 12 can be attached to the step of the first through hole 131. The stepped holes are designed to stably position the camera lens 12 on the transparent cover 13.

Further, in this example, as shown in FIG. 4, the housing 11 is provided with a recess 113, and the bezel 15 is mounted in the recess 113. The design groove 113 can stably mount the bezel 15 while reducing the height of the frame 15 protruding from the casing 11, thereby reducing the size of the terminal device 100 and also improving the appearance aesthetics. Of course, the groove 113 may not be provided.

Further, in the present example, as shown in FIG. 4, the bottom of the frame 15 is provided with a flange 151 extending horizontally to the outside of the frame 15, and the flange 151 is mounted on the groove bottom of the groove 113. The design of the hem 151 can increase the joint strength and reduce the risk of the frame 15 falling off.

Further, in the present example, as shown in FIG. 3, the camera assembly 10 may further include a circuit board 17 located within the housing 11. The circuit board 17 is provided with a notch 171, and the camera 16 is located in the notch 171 and is electrically connected to the circuit board 17. The flash lamp 18 is disposed on the circuit board 17 and electrically connected to the circuit board 17. The notch 171 is designed to avoid air, and the camera 16 is disposed at the notch 171. In this design, the camera 16 is not directly disposed on the circuit board 17, but outside the circuit board 17, so the position of the camera 16 can be adjusted as needed to reduce the overall height of the camera assembly 10, thereby reducing the size of the terminal device 100. . Of course, the circuit board 17 may not be provided with the notch 171, and the camera 16 is directly disposed on the circuit board 17.
