Detailed Description

In this application, camera subassembly is mainly set up in user equipment to make user equipment have and shoot and make a video recording the function. The camera assembly generally includes a lens assembly, an auto-focus motor, and an optical anti-shake motor to collect external scene images. And an image sensor is arranged at a position opposite to the tail end of the lens assembly.

An image sensor: an image sensor is a device that converts an optical signal into an electronic signal. The light rays passing through the lens assembly irradiate on a photosensitive surface of the image sensor, and the photosensitive elements on the photosensitive surface collect and record information such as light intensity of the light rays to form an image. The image sensor may also be referred to as an image sensor, or a light sensing chip, or a light sensing element.

Lens subassembly: the image sensor is arranged on the imaging side of the lens assembly, and external light can be focused on the photosensitive surface of the image sensor through the lens assembly to form clear images. Specifically, the light sensing surface of the image sensor may be perpendicular to the optical axis of the lens assembly. The lens assembly is used for changing the light path of light from the outside by utilizing the refraction effect of the lens, so that the outside scenery picture is focused on the image sensor. The lens assembly generally includes one or more transparent optical lenses (i.e., lenses) disposed at different positions along an axial direction of the lens assembly (i.e., a direction of an optical axis of the lens assembly), and when external light irradiated into the lens assembly advances along the optical axis of the lens assembly, the external light is refracted while passing through the different optical lenses and finally focused on a photosensitive surface of the image sensor, so that the image sensor forms a clear image.

Focus motor (e.g., Auto Focus (AF) motor): when the lens assembly realizes imaging, because different distances exist between the external object and the lens assembly, when the external object with different distances is shot, the distance (namely the image distance) between the optical lens and the image sensor of the lens assembly is usually required to be adjusted, so that the picture can be normally focused on the image sensor. The automatic focusing motor can drive part or all of lenses in the lens assembly to move back and forth along the optical axis direction of the lens assembly, so that light rays of external objects can be focused on the image sensor after passing through the lens assembly, and clear images are formed. The automatic focusing motor can be in a ring or frame structure and is arranged around the circumferential outer side of the lens component, so that the light passing of the lens component can not be influenced when the automatic focusing motor drives the lens in the lens component to move.

Optical Image Stabilization (OIS) motor: when a handheld shooting mode is adopted, the camera assembly can shake due to unstable hand holding, and the lens assembly in the camera assembly can shake accordingly, so that an imaging picture of the lens assembly shakes. The optical anti-shake motor is directly or indirectly connected with the lens assembly and compensates shaking of the camera assembly by controlling the lens assembly to move reversely. Specifically, the vibration of the hand can be detected by a sensor such as a gyro sensor and the like, converted into an electric signal, and processed to control the optical anti-shake motor to move parallel to the light-sensitive surface of the image sensor, so that the imaging offset and shake phenomena caused by hand shake are counteracted. Generally, the optical anti-shake motor can also be sleeved on the circumferential outer side of the lens assembly, so that the influence on the normal light passing of the lens assembly is avoided.

Driving the wire: in the case of an SMA (shape Memory alloy) motor, the drive wires of the SMA motor may be made of SMA (shape Memory alloy) material, and thus may also be referred to as SMA wires. When an electric signal is input to the driving wire, the temperature changes and the length of the driving wire changes accordingly, compared to a state in which no electric signal is input. When the length of the driving wire changes, the movable part of the optical anti-shake motor can be driven to generate displacement relative to the fixed part. For example: some of the drive wires are shorter in length when energized than when not energized, that is, the drive wires contract when energized. The electric signal input to the driving wire may be a PWM (Pulse Width Modulation) signal, where the PWM signal is a high-frequency Pulse signal and generates large electromagnetic wave radiation, and the electromagnetic wave radiation has strong interference to the circuit in the image sensor 4.

The foregoing is an explanation of the various components involved in various embodiments of a camera assembly of the present application to facilitate understanding by those skilled in the art. It should be noted that the above list of components is not a necessary inclusion of components in the camera assembly of the present application.

The application provides a camera subassembly, through with optics anti-shake motor sets up the daylighting side of lens subassembly to keep away from image sensor makes have far away physical distance between optics anti-shake motor and the image sensor.

In addition, the design of camera subassembly in this application can use in periscopic camera module, and the optics anti-shake motor in the periscopic camera module generally adopts the SMA motor.

For the sake of simplicity, the circuit board 5 may serve as the bottom plate 23 of the housing 2. Thus, no additional bottom plate is needed.

As shown in fig. 1 or 3, in one embodiment of the camera head assembly, the lens assembly 3 includes a lens holder 31 and 1 or more optical lenses 32 installed inside the lens holder 31.

As shown in fig. 1 or fig. 3, in an embodiment of the camera assembly, the camera assembly further includes a focusing motor 6, the focusing motor 6 is used for driving the lens assembly 3 to move for focusing, and the focusing motor 6 is located inside the housing 2 and at a position between the bottom plate 23 (or the circuit board 5) and the optical anti-shake motor 1. The electromagnetic interference of the focusing motor 6 to the image sensor 4 is smaller than the electromagnetic interference of the optical anti-shake motor 1 to the impact sensor 4. The focus Motor 6 may be a Voice Coil Motor (VCM) or a piezoelectric Motor. The focusing motor 6 can drive the lens assembly 3 to move along the direction of the optical axis or along the direction parallel to the optical axis, so as to realize focusing.

As shown in fig. 5, the distance between the optical anti-shake motor 1 and the circuit board 5 is L1.

The side plate 22 of the housing 2 is located in a space around the focus motor 6. A support spring or a spring plate is connected between the focusing motor 6 and the side plate 22 or the bottom plate 23 of the housing 2, and the support spring or the spring plate is used for supporting and limiting the focusing motor 6 so as to reduce unnecessary rotation or swing of the focusing motor 6.

As shown in fig. 1 or fig. 3, in an embodiment of the camera assembly, a first lead 14 is connected between the driving wire 13 of the optical anti-shake motor 1 and the circuit board 5, and the first lead 14 is a wire for transmitting signals between the optical anti-shake motor 1 and the circuit board 5. The circuit board 5 outputs an electrical signal (e.g., a PWM signal) to the driving wire 13 through the first lead 14.

The first lead 14 is connected to the circuit board 5 along the outside of the side plate 22 of the housing 2. The first lead 14 may be electrically conducted with the circuit board 5 by soldering to the circuit board 5, or the first lead 14 may be electrically conducted with the circuit board 5 by a connector.

In one embodiment of the camera assembly, the image sensor 4 is provided with a plurality of pins electrically connected to the circuit board 5, as shown in fig. 6. In order to reduce the electromagnetic interference of the electric signal in the first lead 14 to the image sensor 4, the position where the first lead 14 is electrically connected with the circuit board 5 is located far away from the pin of the image sensor 4. For example: for a rectangular image sensor 4, the pins 41 are located on 1 or 2 or 3 sides of the image sensor 4. At least one side of the image sensor 4 is not provided with a pin. The connection position of the first lead 14 to the circuit board 5 is located near the side of the image sensor 4 where no pin 41 is provided. For example: one or two shorter sides of the rectangular image sensor 4 are provided with pins 41, and the connection position of the first lead 14 and the circuit board 5 is located near one longer side of the image sensor 4.

The first lead 14 is electrically connected to the circuit board, but the first lead 14 is not necessarily electrically connected to the image sensor 4, and the farther the first lead 14 is from the image sensor 4, the better, and for the same reason, the farther the first lead 14 is from the pin 41 of the image sensor 4, the better.

As shown in fig. 1 or fig. 3, a second lead 65 is connected between the focusing motor 6 and the circuit board 5, and the second lead 65 is a wire for transmitting signals between the focusing motor 6 and the circuit board 5. The second lead 65 is connected to the circuit board 5 from the outside of the side plate 22 of the case 2. The second lead 65 is electrically conducted with the circuit board 5 by soldering with the circuit board 5, or the second lead 65 is electrically conducted with the circuit board 5 by a connector.

In order to reduce the electromagnetic interference of the electrical signal transmitted in the second lead 65 to the image sensor 4, the second lead 65 is electrically connected to the circuit board 5 at a position away from the pin 41 of the image sensor 4, similar to the first lead 14. For example: the bonding position of the second lead 65 to the circuit board 5 is located near the side of the image sensor 4 where no pin 41 is provided.

The second lead 65 is not required to be electrically connected with the image sensor 4, the second lead 65 is electrically connected with the circuit board 5, the farther the second lead 65 is from the image sensor 4, the better, and for the same reason, the farther the second lead 65 is from the pin 41 of the image sensor 4, the better. By limiting the position where the first lead 14 is connected to the circuit board 5 and the position where the second lead 65 is connected to the circuit board 5 to positions away from the pins 41 of the image sensor 4, the interference of the electric signals in the first lead 14 and the second lead 65 to the image sensor 4 can be reduced, thereby achieving reduction of the stripe noise in the image formed by the image sensor 4.

As shown in fig. 5, the distance between the first lead 14 (or the second lead 65) and the circuit board 5 is L2.

In the case where the circuit board 5 is located outside the bottom plate 23, or the bottom plate 23 serves as the bottom plate 23 of the housing 2 (see fig. 1 or 3), at least a part of the circuit board 5 is located outside the side plate 22. The position where the first lead 14 is connected to the circuit board 5 is located outside the side plate 22 of the case 2. This can reduce the interference of the electrical signal in the first lead 14 with the image sensor 4. A magnetic shield material film for shielding electromagnetic radiation of an electric signal in the first lead 14 may be attached to an inner side wall of the side plate 22 of the case 2 at a position close to the first lead 14.

Similarly, the position where the second lead 65 is connected to the circuit board 5 may also be located outside the side plate 22 of the housing 2. A magnetic shield material film for shielding electromagnetic radiation of an electric signal in the second lead 65 may be attached to an inner side wall of the side plate 22 of the case 2 at a position close to the second lead 65.

In a specific embodiment, as shown in fig. 1 or fig. 3, the second lead wire 65 is connected from the driving part 60 of the focusing motor 6 to the anti-shake fixing part 11 of the optical anti-shake motor 1.

The second lead 65 is similar to the first lead 14, and the second lead 65 passes through a hole (the hole may be the opening 20, or may be another hole other than the opening 20) or a slit provided in the end plate 21 or the side plate 22 of the housing 2 to reach the outside of the housing 2, and passes through the outside of the housing 2 to reach the circuit board 5.

For example: the first lead 14 may pass through one side of the supporting spring or the elastic sheet between the anti-shake fixed part 11 and the anti-shake movable part 12 of the optical anti-shake motor 1. The second lead 65 may pass through one side of the supporting spring or the elastic sheet between the anti-shake fixed part 11 and the anti-shake movable part 12 of the optical anti-shake motor 1. The first lead 14 may be a flexible PCB, and the second lead 65 may also be a flexible PCB.

The focusing immovable part 61 of the focusing motor 6 is fixedly connected to the anti-shake part 12 of the optical anti-shake motor 1, or the focusing immovable part 61 of the focusing motor 6 and the anti-shake part 12 of the optical anti-shake motor 1 are integrally formed. The focusing element 62 of the focusing motor 6 is assembled with the lens assembly 3, or the focusing element 62 of the focusing motor 6 is integrally formed with the lens holder 31 of the lens assembly 3. The focusing immovable part 61 of the focusing motor is disposed outside the focusing movable part 62. The anti-shake part 12 of the optical anti-shake motor 1 is movably connected to the focusing part 62 of the focusing motor 6.

When the driving wire 13 of the optical anti-shake motor 1 drives the anti-shake element 12 of the optical anti-shake motor 1 to move, the anti-shake element 12 of the optical anti-shake motor 1 drives the focusing element 62 and the focusing element 61 of the focusing motor 6 to move, and the focusing element 62 drives the lens assembly 3 to move, so that the lens assembly 3 generates the compensation displacement.

One end of the focusing element 62 of the focusing motor facing the end plate 21 of the housing 2 is movably connected to the anti-shake element 12 of the optical anti-shake motor 1. In this way, the anti-shake moving part 12 of the optical anti-shake motor 1 can drive the focusing moving part 62 and the focusing non-moving part 61 of the focusing motor 6 to move, and because the focusing moving part 62 of the focusing motor 6 is movably connected with the anti-shake moving part 12 of the optical anti-shake motor 1, the focusing moving part 62 of the focusing motor 6 can move relative to the focusing non-moving part 61 of the focusing motor and the anti-shake moving part 12 of the optical anti-shake motor 1 to push the lens assembly 3 to focus.

The anti-shake moving member 12 and the focusing moving member 62 can be movably connected by a spring or a leaf spring, which is connected between the anti-shake moving member 12 and the focusing moving member 62. Thus, the focusing element 62 can move relative to the anti-shake element 12, and the spring or leaf spring limits the distance that the focusing element 62 moves relative to the anti-shake element 12.

The driving wire 13 of the optical anti-shake motor 1 is connected between the anti-shake fixed member 11 and the anti-shake movable member 12 which are stacked, when the driving wire 13 extends and retracts, the anti-shake movable member 12 is driven to move in a direction approximately perpendicular to the optical axis of the lens assembly 3, the anti-shake movable member 12 drives the focusing movable member 62 and the focusing fixed member 61 to move in a direction approximately perpendicular to the optical axis of the lens assembly 3, and the focusing movable member 62 drives the lens assembly 3 to move in a direction approximately perpendicular to the optical axis of the lens assembly 3 so as to compensate for displacement of the camera assembly generated during shaking.

The anti-shake fixed part 11 of the optical anti-shake motor 1 and the housing 2 can be movably connected by a spring or a shrapnel 7. The supporting spring or the elastic sheet 7 between the anti-shake fixed part 11 of the optical anti-shake motor 1 and the housing 2 is used for limiting the moving distance of the anti-shake fixed part 11 of the optical anti-shake motor 1 when the anti-shake fixed part 11 of the optical anti-shake motor 1 moves relative to the housing 2.

When the driving wire 13 of the optical anti-shake motor 1 drives the anti-shake component 12 to move, the anti-shake component 12 drives the second movable component 64 of the focusing motor 6 to move, and the second movable component 64 of the focusing motor 6 drives the lens assembly 3 to move, so that the lens assembly 3 generates the compensation displacement.

The driving component 60 of the focusing motor 6 is disposed between the side plate 22 of the housing 2 and the focusing motor 6, and is used for driving the focusing motor 6 and the lens assembly 3 to move relative to the side plate 22 along the direction of the optical axis or along the direction parallel to the optical axis, so as to achieve focusing. Accordingly, the focusing motor 6 also drives the anti-shake fixed part 11 and the anti-shake movable part 12 of the anti-shake motor 1 to move along the direction of the optical axis or move along the direction parallel to the optical axis.

The first movable piece 63 is disposed opposite to the side plate 22 of the housing 2, the magnet 66 is disposed on the side plate 22 of the housing 2 facing the inner side of the first movable piece 63, the first movable piece 63 is disposed facing the side wall of the side plate 22, the coil 67 interacts with the magnet 66 after being energized to generate a clockwise or counterclockwise moment to push the first movable piece 63, the second movable piece 64, the anti-shake movable piece 12, the anti-shake movable piece 11, and the lens assembly 3 to rotate around the optical axis of the lens assembly 3.

Because the anti-shake fixed part 11 is movably connected with the end plate 21 of the housing 2 (for example, movably connected through a supporting spring or a spring plate), the first movable part 63, the second movable part 64, the anti-shake fixed part 11, and the anti-shake movable part 12 can move relative to the housing 2 to push the lens assembly 3 to focus.

In a specific embodiment, as shown in fig. 4, the second movable member 64 of the focusing motor 6 may be a tubular structure or a frame structure, and the second movable member 64 of the tubular structure or the frame structure is sleeved on the outer side of the lens assembly 3.

The supporting spring or elastic sheet between the focusing motor 6 and the housing 2 may be connected between the first movable member 63 of the focusing motor 6 and the side plate 22 or the bottom plate 23 of the housing 2. In addition, a supporting spring or a spring plate may be connected between the first movable member 63 and the second movable member 64 of the focusing motor 6. The supporting spring or the elastic sheet between the first movable member 63 and the second movable member 64 is used for limiting the relative movement between the first movable member 63 and the second movable member 64.

The plane substantially perpendicular to the optical axis is a plane having an angle with the optical axis of a right angle or an acute angle smaller than 45 degrees or an obtuse angle larger than 135 degrees. The compensation displacement is generally a displacement in a direction substantially perpendicular to an optical axis of the lens assembly. The approximately perpendicular means that an included angle between a straight line in which the direction of the displacement is located and a straight line in which the optical axis is located is a right angle, or an acute angle smaller than 45 degrees, or an obtuse angle larger than 135 degrees.

The term "fixedly attached" in the above embodiments means that the two components are connected together without relative displacement.
