Description

Technical Field

[0001] The present application belongs to the technical field of electronic products, and specifically relates to a camera module and electronic equipment. Background Art

[0002] With the widespread adoption of smartphones and various portable devices, the camera modules integrated into them have become an indispensable tool for users to record their daily lives and create creative works. This has led to increasing consumer demand for camera imaging quality, particularly long-range shooting capabilities and image stability. To achieve a longer equivalent focal length within a limited device thickness, thereby capturing distant scenes, periscope camera modules have become a mainstream feature in electronic devices.

[0003] At present, periscope camera modules generally adopt a single optical image stabilizer (OIS) combined with an autofocus (AF) lens structural design. OIS usually compensates for camera shake by moving the prism to reduce image blur, while AF is responsible for precise focusing to ensure that the subject is clear.

[0004] However, when the camera module performs optical image stabilization compensation, especially when a prism is used for shake compensation, image rotation is inevitably induced in the image, resulting in reduced image quality. Summary of the Invention

[0005] The purpose of the embodiments of the present application is to provide a camera module and an electronic device that can solve the problem of how to avoid image rotation caused by prism movement when performing optical image stabilization compensation in the camera module.

[0013] In a second aspect, an embodiment of the present application provides an electronic device comprising the camera module as described in the first aspect.

DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0026] The terms "first," "second," and the like in the specification and claims of this application are used to distinguish similar objects and are not used to describe a particular order or precedence. It should be understood that the terms used in this manner are interchangeable where appropriate so that the embodiments of this application can be implemented in an order other than those illustrated or described herein. In addition, the term "and / or" in the specification and claims refers to at least one of the connected objects, and the character " / " generally indicates that the objects associated with each other are in an "or" relationship.

[0027] The control method provided in the embodiment of the present application is described in detail below through specific embodiments and their application scenarios in conjunction with the accompanying drawings.

[0028] Please refer to Figures 1 to 8 The embodiment of the present invention provides a camera module, comprising: a supporting bracket 1 and a first OIS assembly 2, an AF lens assembly 3, a second OIS assembly 4, an imaging chip 5 and a control module L arranged on the supporting bracket 1;

[0029] The first OIS assembly 2 is disposed at the front end of the optical path of the AF lens assembly 3. The first OIS assembly 2 includes a first prism 21 and a first driving structure 22. The first driving structure 22 is used to drive the first prism 21 to move along the first direction V1 and / or along the second direction V2.

[0030] The second OIS assembly 4 is disposed at the rear end of the optical path of the AF lens assembly 3. The second OIS assembly 4 includes a second prism 41 and a second driving structure 42. The second driving structure 42 is used to drive the second prism 41 to move along the third direction V3 and / or along the fourth direction V4.

[0031] The imaging chip 5 is disposed at the rear end of the optical path of the second OIS component 4 and is used to receive the light emitted by the second OIS component 4 and form an image;

[0032] The control module L is configured to generate a first control signal and a second control signal; the first driving structure 22 drives the first prism 21 to move along a first direction under the action of the first control signal; and the second driving structure 42 drives the second prism 41 to move along a third direction V3 under the action of the second control signal to correct the image rotation caused by the movement of the first prism 21 along the first direction;

[0033] The control module L is further configured to generate a third control signal and a fourth control signal; the first driving structure 22 drives the first prism 21 to move along the second direction under the action of the third control signal; the second driving structure 42 drives the second prism 41 to move along the fourth direction V4 under the action of the fourth control signal to correct the image rotation generated by the movement of the first prism 21 along the second direction. Figure 7 , which shows a top view of the first prism 21, the second prism 41, the lens 32 and the imaging chip 5; Figure 6 Shown is a side view of the first prism 21, the second prism 41 and the lens 32; Figure 5 Shown is a front view of the first prism 21 , the second prism 41 , the lens 32 and the imaging chip 5 .

[0034] For example, Figure 7 In the embodiment, the first direction V1 is a swinging direction toward the positive direction of the Y axis or a swinging direction toward the negative direction of the Y axis, which can be called a shaking motion of the first prism 21; Figure 6 In the embodiment, the second direction V2 is a swinging direction toward the positive direction of the Z axis or toward the negative direction of the Z axis, which can be called a nodding motion of the first prism 21 .

[0035] For example, Figure 6 In the embodiment, the third direction V3 is a swinging direction toward the positive direction of the Z axis or a swinging direction toward the negative direction of the Z axis, which can be referred to as a nodding motion of the second prism 41; Figure 7 In the embodiment, the fourth direction V4 is a swinging direction toward the positive direction of the X-axis or a swinging direction toward the negative direction of the X-axis, which can be called a shaking motion of the second prism 41 .

[0036] It is understood that when the first prism 21 performs both nodding and shaking motions, the second prism 41 should also perform shaking and nodding motions accordingly to compensate for the image rotation introduced by the first prism 21. In this way, through the coordinated movement of the dual prisms in different directions, the optical path is adjusted, the image rotation problem is resolved, and the image correction function is achieved.

[0037] In the above embodiment, a first optical system (OIS) assembly 2 is disposed at the front end of the optical path of the AF lens assembly 3. The first OIS assembly 2 includes a first prism 21 and a first drive mechanism 22. A second optical system (OIS) assembly 4 is disposed at the rear end of the optical path of the AF lens assembly 3. The second OIS assembly 4 includes a second prism 41 and a second drive mechanism 42. An imaging chip 5 is disposed at the rear end of the optical path of the second OIS assembly 4 to receive light emitted by the second OIS assembly 4 and form an image. When the control module L controls the first drive mechanism 22 to move the first prism 21 a certain distance in the first direction and / or the second direction, the first prism 21 induces image rotation. The control module L controls the second drive mechanism 42 to move the second prism 41 in the third direction and / or the fourth direction, thereby offsetting the image rotation caused by the first prism 21. By distributing the OIS assemblies in front of and behind the AF lens assembly 3 and correcting the matching movement directions of the first and second prisms 41, the present embodiment can accurately offset the image rotation caused by the movement of the first prism 21, thereby reducing image blur caused by rotation or shaking of the camera module itself.

[0038] As an exemplary embodiment, the first drive structure 22 may include a coil unit and a magnet unit. The coil unit is fixed to the support frame 1, and the magnet unit is fixedly connected to the first prism 21. The first control signal generated by the control module L is used to regulate the current in the coil unit. The magnitude and direction of the current determine the strength and polarity of the coil unit's magnetic field. When the current passes through the coil unit, the magnetic field generated by the coil unit forms an interaction force with the magnet unit, thereby driving the magnet unit and the first prism 21 attached to the magnet unit to move in the first direction. The control principle of the third control signal is the same as that of the first control signal and will not be repeated here.

[0039] Similarly, the second drive structure 42 may also include a coil unit and a magnet unit, with the coil unit fixed to the support bracket 1 and the magnet unit fixedly connected to the second prism 41. The second control signal generated by the control module L is used to adjust the current in the coil, with the magnitude and direction of the current determining the strength and polarity of the magnetic field of the coil unit. When the current passes through the coil unit, the magnetic field generated by the coil unit interacts with the magnet unit, thereby driving the magnet unit and the second prism 41 attached to the magnet unit to move in the second direction. The control principle of the fourth control signal is the same as that of the second control signal and will not be repeated here.

[0040] As another exemplary implementation, the first drive structure 22 and the second drive structure 42 may also be stepper motors, and the control module L drives the stepper motors by sending pulse signals; for example, the speed of the stepper motor is controlled by the frequency of the pulse signal, and the rotation angle of the motor is controlled by the number of pulses, thereby realizing motion control of the prism.

[0041] It should be noted that the above driving structures provided in the embodiments of the present application are merely examples, and there are various driving structures that can realize prism movement, and the present invention is not limited to this.

[0042] In some embodiments of the present application, the light incident surface of the first prism 21 and the light emitting surface of the second prism 41 are perpendicular to each other.

[0043] For example, Figure 5 and 6 As shown, the first prism 21 and the second prism 41 are both triangular prism structures, and the three side surfaces of the first prism 21 are respectively the first light incident surface 21a, the first reflecting surface 21c and the first light emitting surface 21b; the three side surfaces of the second prism 41 are respectively the second light incident surface 41a, the second reflecting surface 41c and the second light emitting surface 41b; the first light incident surface 21a of the first prism 21 and the second light emitting surface 41b of the second prism 41 are perpendicular to each other.

[0044] Exemplarily, during specific implementation, the control module L can detect the jitter of the camera module in real time, and calculate the required amount of movement, direction of movement and image rotation of the first prism 21, and then control the first driving structure 22 to move along the first direction and / or the second direction; based on the movement of the first prism 21 and the geometric characteristics of the optical path folding, the control module L can accurately calculate the corresponding amount of movement and direction of movement required by the second prism 41, and then control the second driving structure 42 to move along the third direction and / or the fourth direction to generate image rotations of equal size and opposite direction, thereby completely offsetting the image rotation generated by the first prism 21.

[0045] In the above embodiment, by setting the light-entry surface of the first prism 21 and the light-exit surface of the second prism 41 to be perpendicular to each other, the light path will be deflected at a 90-degree angle when entering the first prism 21 and leaving the second prism 41, and the image rotation generation and compensation mechanism of the two prisms are cleverly adapted in space, so that the motion axis of the second prism 41 and the image rotation generated by it can offset the image rotation generated by the first prism 21 after being twisted by the 90-degree light path folding. Even when the light path has been folded, dynamic compensation correction of the image rotation can still be achieved, ultimately ensuring that the light received by the imaging chip is stable and rotation-free. Moreover, the two prisms move in coordination on their respective light paths to compensate for image rotation. Not only does it achieve anti-shake function and image rotation correction, but it also maximizes space savings.

[0046] In some embodiments of the present application, the first OIS assembly 2 further includes a first prism carrier 23;

[0047] The first prism 21 is disposed on a first prism carrier 23;

[0048] The first prism carrier 23 is fixedly connected to the supporting bracket 1 via a first flexible supporting member 6 , and the first flexible supporting member has the freedom of movement in a first direction V1 and a second direction V2 ;

[0049] The first driving structure 22 includes at least one group of electromagnetic elements, each group of electromagnetic elements includes a first magnet unit 221 and a first coil unit 222, one of the first magnet unit 221 and the first coil unit 222 is arranged on the first prism carrier 23, and the other of the first magnet unit 221 and the first coil unit 222 is arranged on the supporting bracket 1.

[0050] like Figure 1In the figure, the first driving structure 22 includes three groups of electromagnetic elements. The first magnet units 221 in two groups of electromagnetic elements are respectively arranged on the two opposite outer walls of the first prism carrier 23, and generate electromagnetic force by controlling the current in the first coil unit 222 to drive the first prism carrier 23 to move along the first direction V1; the other group of electromagnetic elements is arranged on the bottom wall of the first prism carrier 23 to drive the first prism carrier 23 to move along the second direction V2.

[0051] In this embodiment, the first flexible support member has freedom of movement in both the first direction V1 and the second direction V2, ensuring that the first prism carrier 23 can only move in the first direction V1 and / or the second direction V2, effectively suppressing other unnecessary vibrations or rotations and improving the precision of prism movement. Furthermore, the electromagnetic drive, combined with the lightweight prism carrier and the low-damping flexible support member, results in a low inertia for the entire movable portion, enabling rapid response to control signals and enabling rapid position adjustment of the first prism 21.

[0052] See also Figure 7 In some embodiments of the present application, the first flexible carrier 6 includes:

[0053] A first connector 61, the first connector 61 is fixedly connected to the supporting bracket 1;

[0054] A second connector 62;

[0055] A third connector 63, the third connector 63 is fixedly connected to the first prism carrier 23;

[0056] At least one first flexible connector 64 , the first flexible connector 64 being sandwiched between the first connector 61 and the second connector 62 , and supporting the first prism carrier 23 to swing along a first direction;

[0057] At least one second flexible connector 65 is provided between the second connector 62 and the third connector 63 . The second flexible connector 65 supports the first prism carrier 23 to swing along the second direction.

[0058] For example, see Figure 8In the structure of the first and second flexible connectors 64 and 65, the connection gradually tapers from a thicker connection area at one end toward a flexible central region. Its outer surface consists of opposing first and second curved surfaces, as well as a flat surface adjacent to the first and second curved surfaces. The first and second curved surfaces are positioned opposite each other and are both concave inward. This allows the flexible connectors to exhibit high flexibility and low rigidity in the desired first direction V1 or second direction V2, enabling precise swinging or deformation like an elastic hinge. While maintaining relatively high rigidity in other non-moving directions, it effectively suppresses undesirable parasitic motion, thereby achieving high-precision motion control and image rotation compensation.

[0059] In some embodiments of the present application, the second OIS assembly 4 further includes a second prism carrier 43;

[0060] The second prism 41 is disposed on a second prism carrier 43;

[0061] The second prism carrier 43 is fixedly connected to the supporting bracket 1 via a second flexible supporting member 7. The second flexible supporting member 7 has the degree of freedom of movement in a third direction V3 and a fourth direction V4.

[0062] The second driving structure 42 includes at least one group of electromagnetic elements, each group of electromagnetic elements includes a second magnet unit 421 and a second coil unit 422, one of the second magnet unit 421 and the second coil unit 422 is arranged on the second prism carrier 43, and the other of the second magnet unit 421 and the second coil unit 422 is arranged on the supporting bracket 1.

[0063] It should be noted that the second flexible supporting member 7 can adopt the same structure as the first flexible supporting member 6 , which will not be described in detail here.

[0064] like Figure 1 In the figure, the second driving structure 42 includes three groups of electromagnetic elements. The two second magnet units 421 in the two groups of electromagnetic elements are respectively arranged on the two opposite outer walls of the second prism carrier 43, and the electromagnetic force is generated by controlling the current in the second coil unit 422 to drive the second prism carrier 43 to move along the fourth direction V4; the zeroth group of electromagnetic elements is arranged on the bottom wall of the second prism carrier 43, and is used to drive the second prism carrier 43 to move along the third direction V3.

[0065] In this embodiment, the second flexible support member 7 has freedom of movement in the third direction V3 and the fourth direction V4, ensuring that the second prism carrier 43 can only move along the third direction V3 and / or the fourth direction V4, effectively suppressing other unnecessary vibrations or rotations, and improving the purity and precision of the prism movement. Furthermore, the electromagnetic drive combined with the lightweight prism carrier and the low-damping flexible support member ensures that the entire movable part has low inertia, enabling rapid response to control signals and enabling rapid position adjustment of the second prism 41.

[0066] In some embodiments of this application, see Figure 4 , the load-bearing bracket 1 includes a first frame body 11 and a second frame body 12, and the first frame body 11 and the second frame body 12 are fixedly connected;

[0067] The first OIS assembly 2 and the AF lens assembly 3 are arranged on the first frame 11;

[0068] The second OIS assembly 4 and the imaging chip 5 are disposed on the second frame 12 .

[0069] See also Figure 4 , which shows a schematic diagram of a structure in which the first frame 11 and the second frame 12 are separated. Figure 2 and Figure 3 FIG. 1 is a schematic structural diagram of the first frame 11 and the second frame 12 in an installed state.

[0070] In this embodiment, the camera module is split into two parts, each mounted on a different frame. This allows for more precise optimization of the optical distance and relative position between the two OIS assemblies and the AF lens assembly 3, achieving the most effective image rotation correction while avoiding physical interference between the optical components. Furthermore, by adding a telescopic mechanism between the first frame 11 and the second frame 12, the distance between the AF lens assembly 3 and the second OIS assembly 4 can be adjusted, enabling continuous zoom functionality for the camera module.

[0071] In some embodiments of the present application, the AF lens assembly 3 includes: a lens carrier 31, a lens 32, a guide component 33 and a third driving structure 34;

[0072] The lens 32 is arranged on the lens carrier 31;

[0073] The guide member 33 is provided on the supporting bracket 1;

[0074] The third driving structure 34 includes at least one group of electromagnetic elements, each group of electromagnetic elements includes a third magnet unit 341 and a third coil unit 342, one of the third magnet unit 341 and the third coil unit 342 is set on the lens carrier 31, and the other of the third magnet unit 341 and the third coil unit 342 is set on the supporting bracket 1. The third driving structure 34 is used to drive the lens carrier 31 to move along the fifth direction.

[0075] For example, Figure 1 In the embodiment, the guide member 33 is two slide rails; Figure 5 The second direction is parallel to Figure 5 The X direction in the slide rail is parallel to the Figure 5 As shown, the lens carrier 31 is positioned in the X-axis direction and fixed to the support bracket 1. Two slide grooves are provided on the lens carrier 31, and two slide rails are slidably disposed within the slide grooves. By precisely controlling the current in the third coil unit 342, electromagnetic force can drive the lens carrier 31 to reciprocate a certain distance along the fifth direction, thereby changing the distance between the lens 32 and the second OIS assembly 4 and achieving focal length adjustment. It should be noted that the electromagnetic drive method and slide rails described herein are merely examples and are not intended to be limiting.

[0076] like Figure 1 In the embodiment, the third driving structure 34 includes two groups of electromagnetic elements. The third magnet units 341 in the two groups of electromagnetic elements are respectively arranged on two opposite outer side walls of the lens carrier 31 to drive the second prism carrier 43 to reciprocate along the fifth direction.

[0077] In some embodiments of the present application, the camera module further includes: a first housing 8 and a second housing 9;

[0078] The first shell 8 is disposed on the periphery of the first frame 11 , and the second shell 9 is disposed on the periphery of the second frame 12 .

[0079] Alternatively, as Figure 3 and Figure 4 In the embodiment, the first housing 8 is provided with a window 81 as a light-transmitting area, and the window 81 is directly opposite to the light-incoming surface 21 a of the first prism 21 .

[0080] In the above embodiment, the first shell 8 is fixedly connected to the first frame 11, and the second shell 9 is fixedly connected to the second frame 12. The first shell 8 and the second shell 9 are used to protect the components in the camera module and play a light shielding role.

[0081] In some embodiments of the present application, the control module L includes a first control circuit module L1 and a second control circuit module L2;

[0082] The first control circuit module L1 is electrically connected to the first OIS assembly 2 and the AF lens assembly 3 respectively;

[0083] The second control circuit module L2 is electrically connected to the second OIS assembly 4 .

[0084] Exemplarily, the first control circuit module L1 includes a first flexible printed circuit board (FPCB) and a first chip. The first chip is electrically connected to the first coil unit 222 and the third coil unit 342 via the first FPCB, and is used to control the current magnitude and direction of the circuit in the first coil unit 222 and the third coil unit 342 to respectively drive the movement of the first prism 21 and the AF lens assembly 3. The second control circuit module L2 includes a second FPCB and a second chip. The second chip is electrically connected to the second coil unit 422 via the second FPCB, and is used to control the current magnitude and direction of the current in the second coil unit 422 to drive the movement of the second prism 41. The first chip and the second chip are used to sense changes in the magnetic field. In specific implementations, the first chip and the second chip are fixedly connected to the support bracket 1 by dispensing glue.

[0085] In some embodiments of the present application, Figure 7 In the figure, the first light incident surface 21a of the first prism 21 is covered with a first convex structure 211, and the second light incident surface 41a of the second prism 41 is covered with a second convex structure 411. This structural design can increase the amount of light entering the camera module.

[0086] Optionally, the first light incident surface 21a of the first prism 21 may also be covered with a first groove structure, and the second light incident surface 41a of the second prism 41 may also be covered with a second groove structure to increase the amount of light entering the camera module.

[0087] In addition, an embodiment of the present application also provides an electronic device, including the camera module as described above.

[0088] By integrating the above-mentioned camera module, the electronic device can eliminate image blur caused by camera module shaking. At the same time, the high-precision electromagnetic drive of the AF lens assembly ensures fast and accurate autofocus, enabling the electronic device to output clearer, sharper photos and smoother, shake-free videos. Moreover, the design of the light-inlet surface of the first prism 21 and the light-outlet surface of the second prism 41 being perpendicular to each other enables the light path to be folded 90 degrees inside the camera module, greatly reducing the volume of the camera module and reducing the space occupied by the camera module in the electronic device. The saved internal space can be used to integrate larger capacity batteries or other devices.

[0089] It should be noted that, in this article, the terms "comprise", "include" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device comprising a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, an element defined by the statement "comprises a ..." does not exclude the presence of other identical elements in the process, method, article or device comprising the element. In addition, it should be noted that the scope of the methods and devices in the embodiments of the present application is not limited to performing functions in the order shown or discussed, and may also include performing functions in a substantially simultaneous manner or in the opposite order according to the functions involved. For example, the described method may be performed in an order different from that described, and various steps may also be added, omitted, or combined. In addition, the features described with reference to certain examples may be combined in other examples.

The above-mentioned specific implementation methods are merely illustrative and not restrictive. Under the guidance of this application, ordinary technicians in this field can also make many forms without departing from the purpose of this application and the scope of protection of the claims, all of which are within the protection of this application.
