Further, referring to fig. 6 in combination, fig. 6 is a schematic partial sectional view of a camera head assembly 100 according to some embodiments of the present application, and the bracket 70 may include a main body portion 72 and a supporting portion 73. The main body 72 is connected to the circuit board 10 and the lens 60, and the supporting portion 73 is disposed on an end of the main body 72 close to the lens 60 and connected to the main body 72 and the filter 80. The supporting portion 73 is used for fixing and supporting the filter 80, and the supporting portion 73 encloses and forms a light passing hole 702.

In view of this, in other embodiments of the present application, please refer to fig. 7, and fig. 7 is a schematic cross-sectional structure diagram of a camera head assembly 200 in other embodiments of the present application. Specifically, the camera head assembly 200 provided in the embodiment of the present application is different from the camera head assemblies in the foregoing embodiments in that: the structure of the filter 280 in the present embodiment is different from that of the filter 80 in the previous embodiment. While embodiments of the present application provide that the camera head assembly 200 may generally include the lens 260, the bracket 270, and the filter 280, it is understood that reference may be made to the camera head assembly 100 of the previous embodiments with respect to other structures of the camera head assembly 200, and the description of the embodiments of the present application will not be repeated.
Further, the holder 270 is provided with a light hole 271 facing the lens 260, and reference may be made to the light hole 702 in the foregoing embodiment for the structure of the light hole 271. The optical filter 280 is disposed at one side of the light-passing hole 271 close to the lens 260, and the optical filter 280 covers the light-passing hole 271, so that the light entering the lens 260 is filtered by the optical filter 280 and then enters the photosensitive chip from the light-passing hole 271, thereby preventing the unfiltered light from entering the photosensitive chip.
Specifically, referring to fig. 8, fig. 8 is a schematic structural diagram of a filter 280 according to another embodiment of the present disclosure, in which the filter 280 generally includes a light filtering portion 281 and a fixing portion 282, and the fixing portion 282 is disposed along an edge of the light filtering portion 281. In other words, the optical filter 280 may generally include a light-filtering portion 281 and a fixing portion 282 disposed along an edge of the light-filtering portion 281. The fixing portion 282 is used for fixing the filter 280, that is, the fixing portion 282 is fixedly connected to the supporting portion of the bracket, so as to fix the filter 280 on the side of the light-passing hole 271 close to the lens 260.
It is understood that the fixing portion 282 and the supporting portion of the bracket 270 may be fixedly connected by adhesion, and of course, the fixing portion 282 and the supporting portion of the bracket 270 may be fixedly connected by means of, for example, a snap. Further, the fixing portion 282 is fixedly connected to the supporting portion of the bracket 270, referring to the structure manner of fixedly connecting the filter 80 and the bracket 70 in the foregoing embodiment.
Further, the filter portion 281 is at least partially accommodated in the light transmitting hole 271 to serve as a space for sinking the lens 260, so that the lens 260 can be sunk to the maximum extent while the minimum safety distance between the filter portion 281 of the filter 280 and the lens 260 is ensured, thereby reducing the overall thickness of the camera assembly 200.
In some embodiments of the present disclosure, the lens 260 may include a light incident surface 261 and a light emitting surface 262 oppositely disposed, and the external light enters from the light incident surface 261, and then exits through the light emitting surface 262 and irradiates the filter 280. That is, the light incident surface 261 is disposed away from the filter 280, and the light emitting surface 262 is disposed close to the filter 280.
The camera assembly that this application embodiment provided, through hold the light filtering part with the light filter in logical unthreaded hole, can sink for the camera lens and provide and dodge the space, guarantee that the camera lens can make furthest's sinking, and then can reduce camera assembly's whole thickness.
It is understood that in the field of camera lenses, the lens is generally a convex lens structure, so that light rays are imaged on a photosensitive chip after passing through the lens. In the embodiment of the present application, the light emitting surface 262 is a curved surface.
Accordingly, the optical filter portion 281 may be formed in a curved surface, that is, the optical filter portion 281 is formed to be curved along the fixing portion 282 toward the light passing hole 271. In order to better sink the lens 260 to reduce the overall thickness of the camera assembly 200, the shape of the filter 281 may be adapted to the shape of the light exit surface 262. For example, the shape of the light filter 281 may be substantially the same as the shape of the light exit surface 262, that is, the concave portion of the light exit surface 262 corresponds to the concave portion of the light filter 281, and the convex portion of the light exit surface 262 corresponds to the convex portion of the light filter 281.
Preferably, the filter portion 281 is disposed in parallel with the light emitting surface 262, so that the filter portion 281 serves as an avoiding space for the light emitting surface 262. That is, the shape of the light filter 281 is the same as that of the light exit surface 262, and the distance from each point on the light exit surface 262 to the point on the light filter 281 is the same in the vertical direction (the Z direction shown in fig. 7), so that the light filter 281 can better avoid the light exit surface 262 when the lens 260 is lowered, thereby reducing the overall thickness of the camera assembly 200 to the maximum.
Of course, in other embodiments, please refer to fig. 9, fig. 9 is a schematic partial cross-sectional view of the camera assembly 200 according to other embodiments of the present application, and the light filter 281 is disposed in an arc shape and is partially accommodated in the light hole 271. In the vertical direction (Z direction shown in fig. 9), the filter portion 281 is formed to be curved and extended along the fixing portion 282 toward a direction away from the light exit surface 262. In other words, the arc-shaped surface of the filter 281 is disposed to protrude toward the light-passing hole 271, and is partially accommodated in the light-passing hole 271. The embodiment of the application sets the light-filtering portion 281 as an arc-shaped surface structure, and the arc-shaped surface structure forms an avoiding space when the lens 260 sinks, so that the light-emitting surface 262 of the lens 260 and the light-filtering portion 281 of the optical filter 280 can sink the lens 260 to a certain extent under the condition of keeping the minimum safe distance, thereby reducing the overall thickness of the camera assembly 200.
In other embodiments of the present application, please refer to fig. 10 and 11, in which fig. 10 is a schematic partial sectional structure diagram of a camera head assembly 200 according to other embodiments of the present application, and fig. 11 is a schematic structural diagram of an optical filter 280 according to other embodiments of the present application. The optical filter 280 may generally include a light filtering portion 281 and a fixing portion 282 disposed along an edge of the light filtering portion 281, wherein the light filtering portion 281 and the fixing portion 282 are bent and connected. Specifically, the filter portion 281 generally includes a connection portion 2811 and a filter portion 2812 connected in a bending manner, and the connection portion 2811 is disposed between the fixing portion 282 and the filter portion 2812 for connecting the fixing portion 282 and the filter portion 2812. Furthermore, the connector 2811 is connected with the fixing portion 282 in a bending manner, that is, the connector 281 is formed along the end portion of the fixing portion 282 close to the light-transmitting hole 271 and extends into the light-transmitting hole 271, so that the end portion of the connector 281 far from the fixing portion 282 extends into the light-transmitting hole 271, and further, an escape space is formed when the lens 260 sinks, and the lens 260 can sink to a certain extent, thereby reducing the overall thickness of the camera head assembly 200.
It should be noted that, in order to avoid the connector 2811 affecting the sinking space of the lens 260, an angle α between a plane of the connector 2811 and an extension line of the filter 2812 cannot be too small, that is, if α is 0 °, the connector 2811 is flush with the filter 2812, and the filter 280 is in a planar structure, so that no space can be provided for the lens 260 to sink. Based on this, in the embodiment of the present application, the included angle α is generally 45 to 90 °, and may be, for example, 45 °, 60 °, 75 °, 90 °, and the like.
Further, in the embodiment of the present invention, the connecting sub-portion 2811 and the filter sub-portion 2812 are disposed in a bending connection, so that the whole filter sub-portion 2812 can move in a direction away from the light emitting surface 262, and a whole avoiding space is provided for the lens 260 to sink. On the other hand, the filter portion 2812 is configured to be a planar structure, so that the molding process of the filter 280 is relatively simple, and the production efficiency is improved. In other words, the filter portion 2812 is parallel to the plane of the end surface of the light passing hole 271, that is, the plane of the filter portion 2812 is substantially perpendicular to the vertical direction (the Z direction shown in fig. 10).
It is understood that the connector portion 2811 mainly functions as a connecting portion 2812 and the fixing portion 282, and the connector portion 2811 may be disposed in a plane (as shown in fig. 10), or the connector portion 2811 may be disposed in an arc-shaped plane (as shown in fig. 11).
Referring to fig. 12, fig. 12 is a partial cross-sectional structure diagram of the camera head assembly 200 according to another embodiment of the present invention, when the connector portion 2811 is disposed in a plane, the connector portion 2811 can be vertically bent and connected with the filter portion 2812, that is, the connector portion 2811 and the filter portion 2812 are bent at 90 °. In this case, the upper side of the filter portion 2812 can be used as a space for avoiding the lens 260 when it is lowered, so as to raise the lowering stroke of the lens 260 to the maximum.
Further, in the above embodiment, at least a part of the light-filtering portion 281 of the light-filtering sheet 280 is not in the same plane as the fixing portion 282, so that an escape space is formed when the lens 260 is lowered. That is, in the direction parallel to the axis of the light passing hole 271 (i.e., the Z direction), the end point of the light filtering portion 281 far away from the fixing portion 282 is disposed at a certain distance from the fixing portion 282 to provide a space for the lens 260 to sink. In some embodiments of the present application, the distance between the end point of the light filtering portion 281 far from the fixing portion 282 and the fixing portion 282 in the Z direction is 0.1-0.3mm, for example, may be equal to 0.1mm, 0.2mm, 0.3 mm.
The camera assembly provided by the embodiment of the application can sink the lens to a certain extent under the condition that the minimum safe distance is kept between the light-emitting surface of the lens and the light filtering part of the optical filter by arranging the avoiding space when the lens sinks on the optical filter, so that the overall thickness of the camera assembly is reduced.
The applicant has found in research that the thickness of the camera head assembly 200 in the vertical direction (the Z direction shown in fig. 7) can be reduced by using the above-described filter 280 structure according to the embodiment of the present application. For example, the foregoing embodiments provide a camera head assembly 100 having a first thickness H1 in the vertical direction, the first thickness H1 being approximately 4.49 mm. The camera head assembly 200 provided by the embodiment of the present application has a second thickness H2 in the vertical direction (as shown in fig. 7), and the second thickness H2 is found to be approximately 4.29mm through experiments. I.e., the overall thickness of the camera assembly 200 can be reduced by about 0.2mm, it is obvious that great convenience can be provided for the thinning scheme of the electronic device.
Referring to fig. 13, fig. 13 is a schematic structural diagram of an electronic device 1000 according to some embodiments of the present application, where the electronic device 1000 may be any device having communication and storage functions, for example: the system comprises intelligent equipment with a network function, such as a tablet Computer, a mobile phone, an electronic reader, a remote controller, a Personal Computer (PC), a notebook Computer, vehicle-mounted equipment, a network television, wearable equipment and the like.
