Referring to fig. 3, the camera module 100 may include a housing 130 and a camera 110, wherein a portion of the camera 110 is located inside the housing 130, and another portion of the camera 110 is exposed. The inside of the housing 130 is hollow to form an accommodating space, and a side surface of the housing 130 is provided with a first opening 131, and the camera 110 passes through the first opening 131, so that part of the camera 110 is located in the housing 130. The design of the first opening 131 facilitates the placement of the camera head 110 and the assembly between the camera head 110 and the housing 130.

Specifically, the light incident side of the camera 110 is located outside the housing 130, and the light emergent side of the camera 110 is located inside the housing 130.

With continued reference to fig. 4, in the embodiment of the present application, the camera module 100 may further include: at least one anti-shake assembly 120. In the related art, referring to fig. 5, the anti-shake assembly 120 generally includes a coil 121, a first magnetic member 122, and a magnetic conductive structure 140, where the coil 121 is fixed to the lens barrel 112 of the camera 110, and when the lens barrel 112 of the camera 110 moves after the coil 121 is powered on, magnetic induction lines are cut between the coil 121 and the first magnetic member 122, so as to generate a driving force for preventing 110 from shaking. However, as shown in fig. 6, at the farthest position of the coil 121 from the first magnetic member 122, the magnetic induction lines cut by the coil 121 are too sparse, the generated electromagnetic force is too small to provide enough driving force to push the vibrating part of the camera 110, and the designed anti-shake stroke cannot be reached, thereby affecting the anti-shake function of the camera 110, and thus resulting in a poor anti-shake effect.

Based on this, the present embodiment provides a new camera module 300, and as shown in fig. 7 and fig. 8, in the present embodiment, each anti-shake assembly 120 may include at least: specifically, as shown in fig. 9 and 10, the coil 121 is fixedly connected to the camera 110, the first magnetic member 122 is disposed opposite to the coil 121, the magnetic conductive member 123 is connected to the first magnetic member 122, and a projection of the magnetic conductive member 123 on the coil 121 in a radial direction at least partially overlaps with a projection of the coil 121 on the coil 121.

The first magnetic member 122 is disposed opposite to the coil 121, and a maximum distance between the coil 121 and the first magnetic member 122 is a maximum stroke distance of the anti-shake assembly 120. The magnetic conduction member 123 is connected with the first magnetic member 122, and the projection of the magnetic conduction member 123 and the coil 121 on the radial direction of the coil 121 is at least partially overlapped, so that the magnetic conduction member 123 is relatively close to the coil 121, the concentration degree of magnetic lines of force can be increased, the magnetic flux density of the camera in the movement within the rated stroke range (namely, the density of magnetic induction lines cut by the coil 121 in the stroke of the anti-shake assembly 120 is increased), the minimum electromagnetic force within the rated stroke can be increased, and the anti-shake effect can be improved.

In some embodiments, referring to fig. 8 and 10, the magnetic conducting member 123 may include: the coil 121 may include a first portion 1231 and a second portion 1232, where the first portion 1231 is connected to the second portion 1232, the first portion 1231 is connected to the first magnetic member 122, an end of the second portion 1232 facing away from the first portion 1231 at least partially overlaps a projection of the coil 121 in a radial direction of the coil 121, and the first portion 1231 and the second portion 1232 may enclose to form an accommodating cavity 1233, and the magnetic member is located in the accommodating cavity 1233.

The first part 1231 of the magnetic conducting member 123 and the second part 1232 of the magnetic conducting member 123 enclose to form the accommodating cavity 1233, and the magnetic member is located in the accommodating cavity 1233, so that the first magnetic member 122 is located in the accommodating cavity 1233 formed by the magnetic conducting member 123, so that magnetic lines of force formed between the coil 121 and the magnetic member can be gathered more, and the magnetic flux performance is better.

In addition, in a possible implementation manner, the coil 121 is fixedly connected to the lens barrel of the camera, and the projection of the coil 121 on the lens barrel may be located within the projection of the second portion 1232 on the lens barrel.

The projection of the coil 121 on the lens barrel is located in the projection of the second portion 1232 of the magnetic conductive member 123 on the lens barrel, that is, it is ensured that the projection of the coil 121 on the second portion 1232 of the magnetic conductive member 123 is completely located in the second portion 1232 of the magnetic conductive member 123, and the second portion 1232 of the magnetic conductive member 123 completely covers the coil 121, so that the degree of gathering of magnetic lines of force generated between the coil 121 and the magnetic member can be increased to a great extent, and the overall magnetic flux performance of the anti-shake assembly 120 is improved.

Specifically, as shown in fig. 8 and 9, the lens barrel 112 may include: a main body portion 1121 and a connecting portion 1122, wherein the main body portion 1121 is connected to the connecting portion 1122, the coil 121 is sleeved on the connecting portion 1122 of the lens barrel 112, and the coil 121 is fixedly connected to the connecting portion 1122 of the lens barrel 112. The coil 121 is sleeved on the connecting portion 1122 of the lens barrel 112, and the coil 121 is fixedly connected with the connecting portion 1122 of the lens barrel 112, so that the coil 121 and the lens barrel 112 can be ensured to be relatively fixedly connected.

In the embodiment of the present application, each anti-shake assembly 120 may further include: and a second magnetic member 124, wherein the second magnetic member 124 is connected to the second portion 1232, and the projection of the second magnetic member 124 and the coil 121 in the radial direction of the coil 121 at least partially overlaps.

By providing the second magnetic member 124, the second magnetic member 124 is connected to the second portion 1232 of the magnetic conductive member 123, and the projection of the second magnetic member 124 and the coil 121 in the radial direction of the coil 121 at least partially overlaps, so that the coil 121 is ensured to have the second magnetic member 124 at the farthest position from the first magnetic member 122, and the second magnetic member 124 can guide the magnetic lines of force generated by the first magnetic member 122 to converge more to the edge of the magnetic conductive member 123, thereby increasing the magnetic flux density at the maximum stroke position between the coil 121 and the first magnetic member 122, and further improving the electromagnetic force at the maximum stroke position between the coil 121 and the first magnetic member 122.

It should be noted that, in the embodiment of the present application, the specific arrangement position and arrangement manner of the second magnetic member 124 include, but are not limited to, the following two possible implementation manners:

one possible implementation is: as shown in fig. 9 and 10, the second magnetic member 124 may be located on a side of the second portion 1232 facing the coil 121. As shown in fig. 11, the second magnetic member 124 can guide the magnetic lines of force generated by the first magnetic member 122 to converge more to the edge of the magnetic conductive member 123, so as to increase the magnetic flux density at the maximum stroke between the coil 121 and the first magnetic member 122, and further increase the electromagnetic force at the maximum stroke between the coil 121 and the first magnetic member 122.

As shown in fig. 12, compared to the prior art, the electromagnetic thrust generated by the anti-shake unit 120 in the camera module 100 shown in fig. 9 and 10 is nearly twice as large as the electromagnetic thrust generated by the anti-shake unit 120 in the camera module 100 in the prior art.

Another possible implementation is: as shown in fig. 13, the second magnetic member 124 may be connected to an end of the second portion 1232 facing away from an end of the first portion 1231. As shown in fig. 14, the second magnetic member 124 can guide the magnetic lines of force generated by the first magnetic member 122 to converge more to the edge of the magnetic conductive member 123, so as to increase the magnetic flux density at the maximum stroke between the coil 121 and the first magnetic member 122, and further increase the electromagnetic force at the maximum stroke between the coil 121 and the first magnetic member 122.

Wherein, the size of the second magnetic part 124 in the thickness direction of the second portion 1232 may be larger than the thickness of the second portion 1232. Thus, when the second magnetic member 124 is connected to the end of the second portion 1232 of the magnetic conducting member 123 away from the end of the first portion 1231 of the magnetic conducting member 123, the magnetic conducting performance of the second magnetic member 124 can be ensured.

It should be noted that, in the embodiment of the present application, as shown in fig. 15, the electromagnetic thrust generated by the anti-shake assembly 120 shown in fig. 13 is substantially the same as the electromagnetic thrust generated by the anti-shake assembly 120 shown in fig. 10, and the improvement is close to two times compared with the electromagnetic thrust generated by the anti-shake assembly 120 in the prior art.

In the present embodiment, the dimension of the second magnetic member 124 in the axial direction of the coil 121 may be 1 to 1.5 times the axial dimension of the coil 121. Thus, the magnetic coverage of the second magnetic member 124 can be ensured, and the electromagnetic force of the anti-shake assembly 120 can be improved. Illustratively, the dimension of the second magnetic element 124 in the axial direction of the coil 121 may be 1 time, 1.1 times, 1.2 times, 1.3 times, 1.4 times, 1.5 times, and the like of the axial dimension of the coil 121, which is not limited in the embodiments of the present application.

For example, in some embodiments, the second magnetic member 124 may have a dimension in the axial direction of the coil 121 of 0.7mm, and the coil 121 may have an axial dimension of 0.55mm, such that the dimension of the second magnetic member 124 in the axial direction of the coil 121 is about 1.3 times the axial dimension of the coil 121.

In addition, in the embodiment of the present application, the distance between the first magnetic member 122 and the second portion 1232 of the magnetic conductive member 123 may be 0.1mm to 0.3 mm. The distance between the first magnetic member 122 and the second portion 1232 of the magnetic conductive member 123 is within a certain range, so that the magnetic conductivity of the second portion 1232 of the magnetic conductive member 123 to the first magnetic member 122 can be ensured, and the problem of poor magnetic conductivity when the distance between the first magnetic member 122 and the second portion 1232 of the magnetic conductive member 123 is far away is avoided, thereby improving the electromagnetic force of the anti-shake assembly 120.

Illustratively, the distance between the first magnetic member 122 and the second portion 1232 of the magnetic conductive member 123 may be 0.1mm, 0.15mm, 0.18mm, 0.2mm, 0.25mm, 0.28mm, 0.3mm, and the like, which is not limited in the embodiments of the present application.

It should be noted that the numerical values and numerical ranges referred to in this application are approximate values, and there may be some error due to the manufacturing process, and the error may be considered to be negligible by those skilled in the art.

In addition, it is understood that in some embodiments, a driving assembly (not shown) may be further disposed in the housing 130, and the driving assembly is configured to drive the camera 110 to move. For example, the driving assembly drives the camera 110 to move along the optical axis direction thereof, so as to take pictures at different distances, thereby implementing the focusing function of the camera module 100. In some embodiments, the driving component may further drive the camera 110 to move in a plane where the camera 110 is located, for example, the driving component drives the camera 110 to translate or rotate in the plane where the camera is located, so as to compensate for the amount of hand shake when a user takes a picture, so as to implement the anti-shake function of the camera module 100.

In addition, the camera module 100 may further include a filter assembly (not shown) and an image sensor assembly (not shown). The light filtering component and the image sensing component are sequentially arranged on the light emergent side of the camera 110, light emitted from the light emergent side of the camera 110 irradiates to the light filtering component, is filtered by the light filtering component, irradiates to the image sensing component, and is imaged by the image sensing component.

The filter assembly may include a filter (not shown) and a holder (not shown). The bracket may have an installation opening corresponding to the light exit surface of the camera 110, and the optical filter is installed on the installation opening of the bracket. The ambient light incident on the camera 110 is emitted from the camera 110, and then is irradiated to the optical filter, and is then irradiated to the image sensing assembly after being filtered by the optical filter. The imaging effect of the image sensing assembly can be improved through the filtering effect of the optical filter.

Illustratively, the optical filter can be a blue glass optical filter, and infrared light with longer wavelength is filtered by the blue glass optical filter, so that the true color degree of an image formed by the image sensing assembly is improved, and the problem of image color distortion is avoided.

The image sensing assembly may include an image sensor (not shown) and a second circuit board (not shown), the second circuit board may have a chip area and a package area located at a periphery of the chip area, the image sensor may be disposed in the chip area on the second circuit board, for example, the chip area on the second circuit board may have a pad thereon, and the image sensor may be soldered on the second circuit board through the pad to electrically connect the image sensor and the second circuit board. Wherein, the surface of one side of the image sensor facing the filtering component is the light-sensitive surface.

The light filtering component is fixed on the surface of one side of the second circuit board, on which the image sensor is arranged, and the support of the light filtering component is connected on the second circuit board and is positioned in the packaging area at the periphery of the image sensor. The light-emitting surface of the camera 110, the optical filter and the image sensor are opposite to each other, the optical filter and the image sensor are located on the light-emitting path of the camera 110, and light emitted from the camera 110 sequentially passes through the light-sensitive surfaces of the optical filter and the image sensor and is processed by the image sensor to form an image. For example, the center of the filter and the center of the light-sensing surface of the image sensor are both located on the optical axis of the camera 110.

For example, the second Circuit Board may be a Printed Circuit Board (PCB), a Flexible Printed Circuit Board (FPC), or a rigid-flex Circuit Board, which is not limited in this embodiment.

The filter assembly is located on a portion of the area of the second circuit board, and another portion of the second circuit board is used for electrical connection with an external circuit, for example, the second circuit board is used for electrical connection with the first circuit board 230 in the electronic device 200. Taking the second circuit board as a rigid-flex board as an example, the portion of the second circuit board on which the image sensor is disposed, that is, the portion of the second circuit board on which the filtering component is connected, may be a PCB, the PCB is connected to an FPC, and an electrical connector is disposed at an end of the FPC and electrically connected to the first circuit board 230 of the electronic device 200. Through connecting filtering component on PCB, filtering component's fixed and location of being convenient for, through connect flexible FPC on PCB, the module 100 of being convenient for make a video recording is connected with the outer circuit electricity.

The bracket of the filter assembly may be attached to the second circuit board in the encapsulated area. For example, a packaging adhesive layer is arranged between the bracket and the second circuit board, one surface of the packaging adhesive layer is bonded on the surface of one side of the bracket facing the second circuit board, and the other surface of the packaging adhesive layer is bonded in a packaging area on the second circuit board, so that the bracket is bonded on the second circuit board through the packaging adhesive layer. Or the bracket can be bonded in the packaging area on the second circuit board through a dispensing process.

As an embodiment, the filtering assembly and the image sensing assembly may be fixed outside the housing 130. For example, the support of the filter assembly is adhered to the outer surface of the housing 130 by an encapsulation adhesive layer or a dispensing process. Wherein one side surface of the bracket is adhered to a side surface of the housing 130 facing away from the first opening 131, and the image sensing assembly is adhered to the other side surface of the bracket.

In the case where the filter assembly and the image sensing assembly are located outside the housing 130, taking the second circuit board of the image sensing assembly as a flexible-rigid board as an example, the FPC may be attached to one side of the PCB provided with the image sensor.

As another embodiment, the filtering assembly and the image sensing assembly may be mounted within the housing 130. For example, the filter assembly and the image sensor assembly are disposed in a gap between the light exit side of the camera head 110 and the bottom of the housing 130, the filter assembly and the image sensor assembly are fixed in the housing 130, and the camera head 110 is movable within the housing 130. For example, taking the side of the housing 130 on which the first opening 131 is disposed as the top wall of the housing 130, and the side of the housing 130 opposite to the top wall as the bottom wall of the housing 130, the second circuit board of the image sensing assembly can be adhered to the inner bottom wall of the housing 130.

In addition, if the filtering component and the image sensing component are disposed in the housing 130, for the camera module 100 with the anti-shake function, except for the manner that the driving component drives the camera 110 to move in the plane where the driving component is located, the driving component can drive the image sensing component to move in the plane where the driving component is located, and the shake amount of the hand of the user is compensated by the horizontal movement of the image sensing component, so that the anti-shake function of the camera module 100 is realized.

If the image sensor assembly is in a movable form, the filter assembly and the image sensor assembly are integrally movably mounted in the housing 130. In this regard, continuing to take the example where the second circuit board of the image sensing assembly is a rigid-flexible board, the FPC may surround the periphery of the support of the PCB and the filter assembly, so that the FPC may elastically deform to reserve a sufficient moving space for the PCB and the support.
