Description

Technical Field

[0001]

[0002] This application relates to the field of electronic device technology, and more particularly, to a camera module and an electronic device.

Background Art

[0003] With the rapid development of electronic device technology, electronic devices including camera modules are widely used. For example, devices such as mobile phones and tablet computers are particularly supported by consumers and widely used. In the process of taking pictures, in order to avoid the low-quality imaging effect caused by the shake of the electronic device having a camera module, the electronic device usually includes an optical image stabilization (OIS) mechanism. However, in the OIS mechanism of the camera module in the prior art, usually wire suspension correction or ball bearing correction is used. Specifically, the movable part of the OIS is supported through a suspension wire or a ball, but the support reliability of the suspension wire or the ball is insufficient, thereby causing the shake correction performance to tend to decline. As a result, it has not been able to meet the increasingly high photo-taking and video requirements of customers in a moving state.

Summary of the Invention

[0004] This application provides a camera module and an electronic device to solve the problem of insufficient support reliability of the shake correction mechanism in the camera module in the prior art.

[0005] According to a first aspect, an embodiment of the present application provides a camera module equipped with an image stabilization mechanism. Along the thickness direction of the image stabilization mechanism, the image stabilization mechanism has a first movable frame, a second movable frame, and a third fixed frame connected in sequence. The first movable frame is configured to mount a lens assembly, and one of the first movable frame and the second movable frame is provided with a first sliding groove, and the other of the first movable frame and the second movable frame is provided with a first sliding part, the first sliding part being able to slide along the first sliding groove, and the first sliding groove extending in a first direction. One of the second movable frame and the third fixed frame is provided with a second sliding groove, and the other of the second movable frame and the third fixed frame is provided with a second sliding part, the second sliding part being able to slide along the second sliding groove, and the second sliding groove extending in a second direction.

[0006] In this solution, the first movable frame of the image stabilization mechanism within the camera module can generate movement along a first direction relative to the second movable frame, the second movable frame can generate movement along a second direction relative to the third fixed frame, and the third fixed frame has a two-layer degree of freedom decoupling. In this way, the crosstalk of movement between the first and second movable frames is reduced, the tilt angle of movement is reduced, the accuracy of the movement of the first and second movable frames can be improved, and the image stabilization effect can be improved. The second movable frame and the third fixed frame slide in a fitted manner through a second sliding part and a second sliding groove, and the first movable frame and the second movable frame slide in a fitted manner through a first sliding part and a first sliding groove. This configuration has the advantages of a simple structure and low manufacturing cost, and has low movement resistance, faster response speed, and better movement stability. In addition, in this fitting configuration, the support and restriction between the first movable frame, the second movable frame, and the third fixed frame are more reliable, and therefore the possibility of deflection in the thickness direction is lower. The stress on the first sliding groove and the second sliding groove is more uniform, and the first movable frame, the second movable frame, and Third fixed frame The support reliability between the two is improved, a decrease in the image stabilization effect is avoided, and therefore the reliability of the image stabilization mechanism is improved. In addition, in this fitting configuration, the first sliding groove and the second sliding groove can have a larger stroke space, and therefore the first movable frame and the second movable frame can have a longer movement stroke, thereby improving the image stabilization angle of the image stabilization mechanism, which can meet the requirements of photographing and video recording electronic devices during more violent shaking, and improving the user experience.

[0007] In one possible design, the first sliding groove includes a first positioning groove, the first positioning groove is configured to engage with the first sliding part to restrict the sliding of the first sliding part along the second direction. The second sliding groove includes a second positioning groove, the second positioning groove is configured to engage with the second sliding part to restrict the sliding of the second sliding part along the first direction.

[0008] In this solution, the first positioning groove engages with the first sliding part, thereby preventing the first sliding part from sliding within the first positioning groove along the second direction, and thus preventing the first movable frame from generating displacement in the second direction relative to the second movable frame. The second positioning groove engages with the second sliding part, thereby preventing the second sliding part from sliding within the second positioning groove along the first direction, and thus preventing the second movable frame from generating displacement in the first direction relative to the third fixed frame. In this way, the first movable frame can generate displacement only in the first direction relative to the second movable frame, and the second movable frame can generate displacement only in the second direction relative to the third fixed frame, thereby avoiding motion crosstalk, reducing the tilt angle of motion, improving the accuracy of the displacement of the first and second movable frames, and improving the image stabilization effect of the camera module.

[0009] In one possible design, the first positioning groove and the second positioning groove are V-shaped grooves or trapezoidal grooves.

[0010] In this solution, the openings of the V-shaped groove and the trapezoidal groove gradually increase along the thickness direction. The first sliding part and the second sliding part Thickness directionWhen supported in a fitted manner along a V-shaped groove or trapezoidal groove, the first sliding part and the second sliding part can be positioned at a location where the opening of the V-shaped groove or trapezoidal groove is relatively small. In this way, the displacement of the first sliding part and the second sliding part along the non-extending direction of the V-shaped groove or trapezoidal groove can be limited, thereby preventing the first movable frame from displacing in a direction not predetermined relative to the second movable frame, and preventing the second movable frame from displacing in a direction not predetermined relative to the third fixed frame, and thus the first sliding part Department reference and second sliding The department It can be precisely positioned. In addition, the structure of the V-shaped groove and trapezoidal groove is simple, thereby facilitating mass production, processing, and manufacturing, and thus further reducing the complexity of the camera module mechanism and lowering manufacturing costs.

[0011] In one possible design, the first sliding groove portion further includes a first sliding groove, and the second sliding groove portion further includes a second sliding groove. Along the second direction, the width of the first sliding groove is greater than the width of the first sliding portion. Along the first direction, the width of the second sliding groove is greater than the width of the second sliding portion.

[0012] In this solution, when the first movable frame, the second movable frame, and the third fixed frame are supported and in contact with each other in a fitted manner along the thickness direction in the structural arrangement, the fault tolerance of the first sliding groove and the second sliding groove can be increased, reducing the difficulty of fitting the first sliding groove with the first sliding part and the difficulty of fitting the second sliding groove with the second sliding part, improving the suitability of the camera module and reducing manufacturing difficulty and cost.

[0013] In one possible design, the first sliding groove and the second sliding groove are square grooves or U-shaped grooves.

[0014] In this solution, the opening sizes of the square groove and the U-shaped groove are the same in the thickness direction. When the first movable frame, the second movable frame, and the third fixed frame are supported and in contact with each other in a fitted manner along the thickness direction, the square groove or U-shaped groove, and the first and second sliding parts can implement support and restriction functions only in the thickness direction, but do not implement a restriction function in directions of movement that are not predetermined. In this way, the first and second sliding parts can move smoothly along predetermined directions of movement, and it is certain that the fault tolerance of the first and second sliding grooves will increase.

[0015] In one possible design, the first sliding part and the second sliding part have a semi-cylindrical or hemispherical structure.

[0016] In this solution, when the first and second sliding parts have a semi-cylindrical or hemispherical structure, the contact area between the first and second sliding grooves can be reduced, thereby reducing the damping force and making it easier to drive. Therefore, a faster response speed is obtained, and the image stabilization efficiency of the camera module is improved. In addition, the end portion of the semi-cylindrical or hemispherical structure has a smooth curved surface, and therefore dents due to stress concentration when the first and second sliding grooves are in contact do not easily occur. Therefore, the first and second sliding grooves have better durability, and the camera module The drop reliability has been improved. Camera module The service life will be extended.

[0017] In one possible design, the first movable frame, the second movable frame, and the third fixed frame are all integrally injection-molded structures.

[0018] In this solution, if the first movable frame, the second movable frame, and the third fixed frame are all integrally injection-molded structures, that is, if no other components are required to support the first movable frame, the second movable frame, and the third fixed frame, the number of components in the camera module can be further reduced, manufacturing costs can be further reduced, and manufacturing efficiency can be improved.

[0019] In one possible design, the first movable frame further includes a first body, the second movable frame further includes a second body, and the third fixed frame further includes a third body. The first sliding part is detachably connected to the first body or the second body. The second sliding part is detachably connected to the second body or the third body.

[0020] In this solution, the structure can further improve the fitting tolerance of the first movable frame, the second movable frame, and the third fixed frame, and the positions of the first sliding part and the second sliding part can be adjusted based on the actual structure in the manufacturing process. Thus, the first movable frame, the second movable frame, and the third fixed frame can effectively support and connect each other in a fitting manner, thereby improving the manufacturing efficiency of the camera module. In addition, the first sliding part and the second sliding part can be replaced if they become severely worn, thereby reducing subsequent maintenance costs. Furthermore, in the structural arrangement, the material of the first sliding part and the second sliding part may be a different material from the material of the first movable frame, the second movable frame, and the third fixed frame, thereby improving the wear resistance of the first sliding part and the second sliding part and extending their service life.

[0021] In one possible design, a lubricating material is placed inside the first and second sliding grooves. The lubricating material is a lubricating grease or lubricating oil.

[0022] In this solution, the lubricating material is added to the first sliding groove portion and the second sliding groove portion, thereby further reducing the sliding friction between the first sliding portion and the first sliding groove portion, and between the second sliding portion and the second sliding groove portion. Therefore, the response speed can be improved, the power consumption can also be reduced, and the control accuracy of the first movable frame and the second movable frame is improved.

[0023] In a possible design, the camera module further includes a magnet, the shake correction mechanism further has a shake correction coil, and the shake correction coil is configured to drive the magnet to move along the first direction or the second direction. The magnet is fastened to the first movable frame, the shake correction coil is fastened to the third fixed frame, and the shake correction coil and the magnet are arranged in a corresponding relationship.

[0024] In this solution, when the shake correction mechanism of the camera module operates, the coil is energized to generate a magnetic flux, thereby controlling the magnet so that the magnet can drive the first movable frame to move to generate a corresponding displacement. Therefore, this structure can provide a driving force for the shake correction mechanism, whereby the first movable frame and the second movable frame of the shake correction mechanism slide based on the direction and displacement amount of the shake of the lens assembly, compensate for the direction and displacement amount of the shake of the lens assembly, and thus the shake correction function can be implemented.

[0025] In a possible design, the shake correction mechanism further has a magnetic sheet, and the magnetic sheet is fastened to the side of the third fixed frame away from the second movable frame. The magnetic sheet and the magnet can attract each other to press the third fixed frame against the first movable frame.

[0026] In this solution, the magnetic sheet and the magnet can attract each other. Therefore, the third fixed frame is pressed against the first movable frame. Thus, the first movable frame, the second movable frame, and the third fixed frame come into closer contact and fit with each other in the thickness direction, making the structure more stable and difficult to separate. Therefore, the structural stability of the camera module is improved.

[0027] In a possible design, the shake correction mechanism further includes a position detection sensor, and the position detection sensor is arranged on the third fixed frame and is configured to detect the magnetic field change of the magnet and feedback the positions of the first movable frame and the second movable frame. The position detection sensor is a Hall element or a tunneling magnetoresistance sensor.

[0028] In this solution, the position detection sensor detects the magnetic field and determines the movement position of the magnet by detecting the magnetic field change of the magnet, thereby determining the movement positions of the first movable frame and the second movable frame, and can feedback the real-time position changes of the first movable frame and the second movable frame. Therefore, the camera module can control the magnitude of the current in the coil based on the real-time position changes of the first movable frame and the second movable frame. In this way, by driving the magnet, closed-loop control of the positions of the first movable frame and the second movable frame is implemented, and the control accuracy of the first movable frame and the second movable frame is further improved.

[0029] In a possible design, the camera module further includes an autofocus mechanism, and the autofocus mechanism is configured to implement autofocus of the camera module. The autofocus mechanism is arranged on the side of the first movable frame away from the second movable frame.

[0030] In this solution, the autofocus mechanism is positioned so that the camera module can implement autofocus while simultaneously implementing image stabilization. Therefore, the photographic effect of the electronic device in multiple motion modes is ensured, improving the user experience.

[0031] In one possible design, the autofocus mechanism includes a focus coil, which is located inside the magnet. The focus coil is either a single annular coil or is formed by combining multiple coils.

[0032] In this solution, when the autofocus mechanism is operating, the focus coil is energized to generate a magnetic flux, which acts on a magnet to drive the autofocus mechanism, thereby implementing the autofocus function. In addition, based on the specific structure and usage scenario of the camera module , magnetic The crystal, focus coil, and image stabilization coil may have different layouts.

[0033] According to a second aspect, this application relates to a housing, and The first An electronic device is provided comprising a camera module in any one of the first embodiment and any possible implementation of the first embodiment. The camera module is mounted within the housing. Since the camera module has the aforementioned technical effects, the electronic device including the camera module also has the corresponding technical effects. Further details are again not described herein.

[0037] The accompanying drawings of this specification are incorporated herein by reference, constitute part of this specification, illustrate embodiments conforming to this application, and are used in conjunction with this specification to illustrate the principles of this application. [Modes for carrying out the invention]

[0038] To better understand the technical solution of this application, embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0039] In a particular embodiment, the present application will be described in further detail below with reference to a specific embodiment and the accompanying drawings.

[0040] In the photographic process, to avoid poor image quality caused by shaking of the electronic device containing the camera module, the electronic device usually includes an Optical Image Stabilization (OIS) mechanism. However, in conventional camera module OIS mechanisms, wire suspension stabilization or ball bearing stabilization is usually used. In wire suspension stabilization, a suspension wire is used to support the movable part of the OIS. However, in this structure, although the suspension wire plays both a support and transmission role, the output limit of the suspension wire prevents an increase in the elastic modulus, resulting in low strength. During translational motion over long strokes, the support from the suspension wire deflects in the thickness direction. As a result, the image stabilization performance decreases. In ball bearing stabilization, multiple balls are used to support the entire movable part of the OIS. Magnetic attraction acts on the movable and fixed parts to press the balls and maintain a stable structure. However, in this structure, the balls are in contact with a plane. In systems with large mass, indentations may occur on the contact surface during a fall. As a result, the image stabilization performance decreases. The suspension wires and ball support reliability are insufficient, which tends to degrade image stabilization performance. As a result, it fails to meet the increasingly demanding photography and video requirements of customers in motion.

[0041] To solve the aforementioned technical problems, the embodiments of this application provide a camera module in the prior art. Ru To address the problem of insufficient support reliability of the image stabilization mechanism, a camera module 10 that can be mounted within an electronic device is provided. The electronic device may be any electronic device capable of taking photographs, such as a mobile phone, tablet computer, notebook computer, artificial intelligence (AI) device, wearable device, or smart home device. The specific form of the electronic device is not particularly limited in the embodiments of this application.

[0042] To better understand the technical solution of this application, embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0043] Embodiments of this application provide a camera module 10. As shown in Figures 1 to 4, the camera module 10 includes an image stabilization mechanism 1. Along the thickness direction Z of the image stabilization mechanism 1, the image stabilization mechanism 1 includes a sequentially connected first movable frame 11, a second movable frame 12, and a third fixed frame 13. The first movable frame 11 is configured to be mounted on a lens assembly, and one of the first movable frame 11 and the second movable frame 12 is provided with a first sliding groove 111, and the other of the first movable frame 11 and the second movable frame 12 is provided with a first sliding portion 121, the first sliding portion 121 being able to slide along the first sliding groove 111, the first sliding groove 111 extending along a first direction X. One of the second movable frame 12 and the third fixed frame 13 is provided with a second sliding groove 122, and the other of the second movable frame 12 and the third fixed frame 13 is provided with a second sliding part 131, the second sliding part 131 being able to slide along the second sliding groove 122, the second sliding groove 122 extending along a second direction Y.

[0044] If the camera module 10 shakes, it may cause the lens assembly to shake. Therefore, if the camera module 10 shakes, the first movable frame 11 and the second movable frame 12 can be driven to move the lens assembly in the opposite direction based on the direction and displacement of the lens assembly shake, thereby compensating for the direction and displacement of the lens assembly shake. This effectively overcomes the low-quality imaging caused by the shaking of the camera module 10 and implements the image stabilization effect of the image stabilization mechanism 1.

[0045] In this embodiment, as shown in Figures 4 to 6, the second movable frame 1 of the image stabilization mechanism 1 2 isThrough the fitting between the second sliding portion 131 and the second sliding groove portion 122, a displacement in the second direction Y can be generated relative to the third fixed frame 13. Therefore, the first movable frame 11 moves as the second movable frame 12 moves along the second direction Y, and a displacement in the second direction Y can be generated relative to the third fixed frame 13. In the first movable frame 11 and the second movable frame 12, through the fitting between the first sliding portion 121 and the first sliding groove portion 111, the first movable frame 11 moves relative to the second movable frame 12, and a displacement in the first direction X can be generated. Therefore, the first movable frame 11 can generate displacements in the first direction X and the second direction Y relative to the third fixed frame 13. The lens assembly is mounted on the first movable frame 11, and therefore the first movable frame 11 can drive the lens assembly to move along the first direction X or the second direction Y. In addition, when the first movable frame 11 simultaneously generates movement along the first direction X and the second direction Y, the first movable frame 11 can generate movement in the direction of the force resulting from the movement along the first direction X and the second direction Y, thereby generating a combined displacement, and thus the lens assembly can be driven to generate a displacement in this direction, thereby implementing the image stabilization function of the camera module 10.

[0046] In this embodiment of the present application, as shown in Figures 7 and 8, the first movable frame 11 of the image stabilization mechanism 1 in the camera module 10 can generate movement along a first direction X relative to the second movable frame 12, the second movable frame 12 can generate movement along a second direction Y relative to the third fixed frame 13, and the third fixed frame 13 has two-layer degree of freedom decoupling. In this way, the crosstalk of movement between the first movable frame 11 and the second movable frame 12 is reduced, the tilt angle of motion is reduced, the accuracy of the movement of the first movable frame 11 and the second movable frame 12 can be improved, and the image stabilization effect can be improved. The second movable frame 12 and the third fixed frame 13 slide in a fitted manner through the second sliding part 131 and the second sliding groove 122, and the first movable frame 11 and the second movable frame 12 slide in a fitted manner through the first sliding part 121 and the first sliding groove 111. This configuration has the advantages of a simple structure and low manufacturing cost, and offers low motion resistance, faster response speed, and motion stability. In addition, in this fitting configuration, the support and restriction between the first movable frame 11, the second movable frame 12, and the third fixed frame 13 are more reliable, and therefore the possibility of deflection in the thickness direction Z is low. The stress on the first sliding groove 111 and the second sliding groove 122 is more uniform, and the first movable frame 11, the second movable frame 12, and Third fixed frame The support reliability between the 13 is improved, a decrease in the image stabilization effect is avoided, and therefore the reliability of the image stabilization of the image stabilization mechanism 1 is improved. In addition, in this fitting configuration, the first sliding groove 111 and the second sliding groove 122 can have a larger stroke space, and therefore the first movable frame 11 and the second movable frame 12 can have a longer movement stroke, thereby improving the image stabilization angle of the image stabilization mechanism 1, which can meet the requirements of photographing and videoing electronic devices during more violent shaking, and improving the user experience.

[0047] In the specific embodiments shown in Figures 5 to 8, the first movable frame 11 and the second movable frame 12 slide in a fitted manner through four first sliding parts 121 and four first sliding grooves 111, and the second movable frame 12 and the third fixed frame 13 slide in a fitted manner through four second sliding parts 131 and four second sliding grooves 122. The four first sliding parts 121, four first sliding grooves 111, four second sliding parts 131, and four second sliding grooves 122 are: These are provided at the four corners of the first movable frame 11, the second movable frame 12, and the third fixed frame 13, thereby improving the stability of support and movement, and avoiding interference between other components of the camera module 10 and between both the sliding grooves and sliding parts. Naturally, the number of mating sliding parts and sliding grooves may be adjusted based on the specific structure, for example, six or eight. Alternatively, the sliding parts and sliding grooves may be provided to correspond to different positions, provided that the sliding parts and sliding grooves can slide in a mating manner. This is not limited to the foregoing.

[0048] In addition, as shown in Figures 1 to 3, the camera module 10 further includes a housing 4. A third fixed frame 13 is fastened to the housing 4 and, together with the housing 4, surrounds the housing space. Components of the image stabilization mechanism 1, such as the first movable frame 11, the second movable frame 12, and the debouncing circuit board assembly 17, are housed within the housing space. This improves the structural stability of the camera module 10 and further improves the reliability of image stabilization by avoiding interference between the camera module 10 and other components of the electronic device.

[0049] In one particular embodiment, as shown in Figures 7 and 8, the first sliding groove 111 includes a first positioning groove 111a. The first positioning groove 111a is configured to engage with the first sliding part 121 to restrict the sliding of the first sliding part 121 along a second direction Y. The second sliding groove 122 includes a second positioning groove 122a. The second positioning groove 122a is configured to engage with the second sliding part 131 to restrict the sliding of the second sliding part 131 along a first direction X.

[0050] In this embodiment, as shown in Figures 7 and 9, the first positioning groove 111a engages with the first sliding part 121, thereby preventing the first sliding part 121 from sliding within the first positioning groove 111a along the second direction Y, and thus preventing the first movable frame 11 from being displaced in the second direction Y relative to the second movable frame 12. The second positioning groove 122a engages with the second sliding part 131, thereby preventing the second sliding part 131 from sliding within the second positioning groove 122a along the first direction X, and thus preventing the second movable frame 12 from being displaced in the first direction X relative to the third fixed frame 13. In this way, the first movable frame 11 can generate displacement in the first direction X relative to the second movable frame 12, and the second movable frame 12 can generate displacement in the second direction Y relative to the third fixed frame 13. This avoids motion crosstalk, reduces the tilt angle of motion, improves the accuracy of the displacement of the first movable frame 11 and the second movable frame 12, and improves the image stabilization effect of the camera module 10.

[0051] In one particular embodiment, as shown in Figures 7 to 9, the first positioning groove 111a and the second positioning groove 122a are V-shaped grooves or trapezoidal grooves.

[0052] In this embodiment, as shown in Figures 7 to 9, the openings of the V-shaped groove and the trapezoidal groove gradually increase along the thickness direction Z. When the first sliding part 121 and the second sliding part 131 are supported in a fitted manner along the Z direction using the V-shaped groove or the trapezoidal groove, the first sliding part 121 and the second sliding part 131 can be positioned at a location where the opening of the V-shaped groove or the trapezoidal groove is relatively small. In this way, the displacement of the first sliding part 121 and the second sliding part 131 along the non-extending direction of the V-shaped groove or the trapezoidal groove can be limited, thereby preventing the first movable frame 11 from displacing the second movable frame 12 in directions not predetermined, and preventing the second movable frame 12 from displacing the third fixed frame 13 in directions not predetermined, and thus the first sliding part 121 and the second sliding part 131 can be precisely positioned. In addition, the structure of the V-shaped groove and trapezoidal groove is simple, thereby facilitating mass production, processing, and manufacturing, and thus further reducing the complexity of the mechanism of the camera module 10 and lowering manufacturing costs.

[0053] In the specific embodiments shown in Figures 7 to 9, the first positioning groove 111a and the second positioning groove 122a are V-shaped grooves. This further reduces manufacturing difficulties and improves production efficiency. Naturally, the first position Determining groove Provided that the displacement of the first sliding portion 121 and the second sliding portion 131 in the non-extending direction within the 111a and the second positioning groove 122a can be restricted, the first positioning groove 111a may be a V-shaped groove, the second positioning groove 122a may be a trapezoidal groove, or the first positioning groove 111a and the second positioning groove 122a may be of other shapes and structures. This is not limited herein.

[0054] In one particular embodiment, as shown in Figures 7, 8, and 10, the first sliding groove 111 further includes a first sliding groove 111b, and the second sliding groove 122 further includes a second sliding groove 122b. In the second direction Y, the width of the first sliding groove 111b is greater than the width of the first sliding portion 121. In the first direction X, the width of the second sliding groove 122b is greater than the width of the second sliding portion 131.

[0055] In this embodiment, as shown in Figures 7, 8, and 10, when the first movable frame 11, the second movable frame 12, and the third fixed frame 13 are supported and in contact with each other in a fitted manner along the thickness direction Z in the structural arrangement, the fault tolerance of the first sliding groove 111 and the second sliding groove 122 can be increased, reducing the difficulty of fitting the first sliding groove 111 with the first sliding part 121 and the difficulty of fitting the second sliding groove 122 with the second sliding part 131, improving the suitability of the camera module 10 and reducing manufacturing difficulty and cost.

[0056] In one particular embodiment, as shown in Figures 7, 8, and 10, the first sliding groove 111b and the second sliding groove 122b are square grooves or U-shaped grooves.

[0057] In this embodiment, as shown in Figures 7, 8, and 10, the opening sizes of the square groove and the U-shaped groove are the same in the thickness direction Z. When the first movable frame 11, the second movable frame 12, and the third fixed frame 13 are supported and in contact with each other in a fitted manner along the thickness direction Z, the square groove or U-shaped groove, and the first sliding portion 121 and the second sliding portion 131 can implement a support and limiting function only in the thickness direction Z, but do not implement a limiting function in unset directions of movement. In this way, the first sliding portion 121 and the second sliding portion 131 can move smoothly along the set directions of movement, and it is certain that the fault tolerance of the first sliding groove 111 and the second sliding groove 122 will increase.

[0058] In the specific embodiments shown in Figures 7, 8, and 10, the first sliding groove 111b and the second sliding groove 122b are square grooves. This further reduces manufacturing difficulties and improves production efficiency. Of course, provided that the first sliding groove 111b and the second sliding groove 122b can perform tolerance functions, the first sliding groove 111b and the second sliding groove 122b may, in alternative ways, be of other structures. This is not limited herein.

[0059] In addition, in the non-extending direction of the sliding groove, the positioning groove can be positioned on one side of the sliding plane of the frame, and the sliding part can be positioned on the other side of the sliding plane, thereby ensuring a tolerance effect. For example, in the embodiments shown in Figures 7 and 8, two first positioning grooves 111a and two first sliding grooves 111b are sequentially arranged on the first movable frame 11 along a second direction Y, and two second positioning grooves 122a and two second sliding grooves 122b are sequentially arranged on the second movable frame 12 along a first direction X.

[0060] In one particular embodiment, as shown in Figures 5, 6, 10, and 11, the first sliding portion 121 and the second sliding portion 131 have a semi-cylindrical or hemispherical structure.

[0061] In this embodiment, as shown in Figures 5, 6, 10, and 11, when the first sliding portion 121 and the second sliding portion 131 have a semi-cylindrical or hemispherical structure, the contact area with the first sliding groove 111 and the second sliding groove 122 can be reduced, thereby reducing the damping force and making it easier to drive the first sliding portion 121 and the second sliding portion 131. Therefore, a faster response speed is obtained, and the image stabilization efficiency of the camera module 10 is improved. In addition, the end portion of the semi-cylindrical or hemispherical structure has a smooth curved surface, and therefore dents due to stress concentration when the first sliding groove 111 and the second sliding groove 122 are in contact do not easily occur. Therefore, the first sliding groove 111 and the second sliding groove 122 have better durability. Camera module The drop reliability has been improved. Camera module The lifespan of the product will improve.

[0062] Naturally, the first sliding portion 121 and the second sliding portion 131 may have other structures, but this is not limited to what is described herein.

[0063] In one particular embodiment, as shown in Figures 4, 5, 6, 9, and 10, the first movable frame 11, the second movable frame 12, and the third fixed frame 13 are integrally injection-molded structures.

[0064] In this embodiment, as shown in Figures 4, 5, 6, 9, and 10, if the first movable frame 11, the second movable frame 12, and the third fixed frame 13 are all integrally injection-molded structures, that is, if no other components are required to support the first movable frame 11, the second movable frame 12, and the third fixed frame 13, the number of components in the camera module 10 can be further reduced, manufacturing costs can be further reduced, and manufacturing efficiency can be improved.

[0065] In another specific embodiment, as shown in Figures 5, 6, and 12, the first movable frame 11 further includes a first body 112, the second movable frame 12 further includes a second body 123, and the third fixed frame 13 further includes a third body 132. The first sliding portion 121 is detachably connected to the first body 112 or the second body 123, and the second sliding portion 131 is detachably connected to the second body 123 or the third body 132.

[0066] In this embodiment, as shown in Figures 5, 6, and 12, the structure can further improve the fitting tolerance of the first movable frame 11, the second movable frame 12, and the third fixed frame 13, and the positions of the first sliding part 121 and the second sliding part 131 can be adjusted based on the actual structure in the manufacturing process, so that the first movable frame 11, the second movable frame 12, and the third fixed frame 13 can effectively support and connect each other in a fitting manner, thereby improving the manufacturing efficiency of the camera module 10. In addition, the first sliding part 121 and the second sliding part 131 can be replaced if they become severely worn, thereby reducing subsequent maintenance costs. In addition, in terms of structural arrangement, the material of the first sliding part 121 and the second sliding part 131 may be a different material from the material of the first movable frame 11, the second movable frame 12, and the third fixed frame 13, thereby improving the wear resistance of the first sliding part 121 and the second sliding part 131 and extending the service life of the first sliding part 121 and the second sliding part 131.

[0067] If the material of the first sliding part 121 and the second sliding part 131 differs from the material of the first movable frame 11, the second movable frame 12, and the third fixed frame 13, the first sliding part 121 and the second sliding part 131 may be cylindrical, semi-cylindrical, spherical, hemispherical, or similar structures made of a material such as stainless steel. This is not limited to the foregoing. Naturally, the material of the first sliding part 121 and the second sliding part 131 may, alternatively, be the same as the material of the first movable frame 11, the second movable frame 12, and the third fixed frame 13 in order to reduce manufacturing costs. This is not limited to the foregoing.

[0068] In addition, in implementation solutions, the first sliding portion 121 may be connected to the first body 112 or the second body 123 via a clamp or similar, and the second sliding portion 131 may be connected to the second body 123 or the third body 132 via a clamp or similar. This is not limited to the foregoing. For example, in a particular embodiment shown in Figure 2, the second movable frame 12 is constructed such that the first sliding portion 121 is detachably connected to the second body 123. The second body 123 may be provided with a clamp portion 124, so that the first sliding portion 121 can be clamped to the clamp portion 124, thereby reducing the difficulty of assembling the first sliding portion 121. Similarly, the first movable frame 11 and the third fixed frame 13 may also be of this construction, or of course, of other combinations. This is not limited to the foregoing.

[0069] In another implementation solution, a V-shaped or trapezoidal mounting groove that engages with the first sliding portion 121 may be provided on the first body 112 or the second body 123, and the first sliding portion 121 is positioned within the mounting groove. In addition, the V-shaped or trapezoidal mounting groove can also precisely position the first sliding portion 121 on the first body 112 or the second body 123 to avoid crosstalk of movement. Similarly, the fitting between the second sliding portion 131 and the second body 123 or the third body 132 may be arranged in this manner. This is not limited to the foregoing.

[0070] In one particular embodiment, as shown in Figures 7 and 8, a lubricating material is placed inside the first sliding groove 111 and the second sliding groove 122. The lubricating material is a lubricating grease or lubricating oil.

[0071] In this embodiment, as shown in Figures 7 and 8, lubricating material is added to the first sliding groove 111 and the second sliding groove 122, thereby further reducing sliding friction between the first sliding part 121 and the first sliding groove 111, and between the second sliding part 131 and the second sliding groove 122. Consequently, response speed is improved, power consumption is reduced, and the control accuracy of the first movable frame 11 and the second movable frame 12 is improved.

[0072] Naturally, the lubricating material may be, by alternative means, another lubricating material such as graphite. This is not limited to the foregoing.

[0073] In one particular embodiment, as shown in Figures 3 and 13, the camera module 10 further includes a magnet 2, and the image stabilization mechanism 1 further includes an image stabilization coil 14. The image stabilization coil 14 is configured to drive the magnet 2 to move along a first direction X or a second direction Y. The magnet 2 is fastened to a first movable frame 11, and the image stabilization coil 14 is fastened to a third fixed frame 13, and the image stabilization coil 14 is positioned in correspondence with the magnet 2.

[0074] In this embodiment, as shown in Figures 3 and 13, when the image stabilization mechanism 1 of the camera module 10 is operating, the coil 14 is energized to generate a magnetic flux, thereby controlling the magnet 2 to move so that it can drive the first movable frame 11 and generate a corresponding displacement. Thus, this structure can provide a driving force to the image stabilization mechanism 1, so that the first movable frame 11 and the second movable frame 12 of the image stabilization mechanism 1 slide based on the direction and amount of vibration of the lens assembly to compensate for the direction and amount of vibration of the lens assembly, and thus implement the image stabilization function.

[0075] As shown in Figures 13 and 14, a plurality of protrusions 133 may be provided on the third fixed frame 13 to facilitate the positioning, fastening, and mounting of the coil 14. Recesses may be provided on the first movable frame 11 to facilitate the fastening and mounting of the magnet 2. In this way, displacement of the magnet 2 and coil 14 during shaking or falling is prevented, improving the structural stability and fall reliability of the camera module 10.

[0076] In addition, as shown in Figures 2 and 3, the debouncing circuit board assembly 17 is mounted on the third fixed frame 13, and thus the electronic device can supply power to the image stabilization coil 14 through the debouncing circuit board assembly 17 to implement the image stabilization function of the image stabilization mechanism 1.

[0077] In one particular embodiment, as shown in Figures 3 and 14, the image stabilization mechanism 1 further includes a magnetic sheet 16. The magnetic sheet 16 is fastened to the side of the third fixed frame 13 that is away from the second movable frame 12. The magnetic sheet 16 and the magnets 2 are attracted to each other and can press the third fixed frame 13 against the first movable frame 11.

[0078] In this embodiment, as shown in Figures 3 and 14, the magnetic sheet 16 and the magnet 2 can attract each other, so the third fixed frame 13 is pressed against the first movable frame 11, so the first movable frame 11, the second movable frame 12, and the third fixed frame 13 come into closer contact and fit together in the thickness direction Z, making the structure more stable and difficult to separate. Thus, the structural stability of the camera module 10 is improved.

[0079] As shown in Figures 3 and 14, the magnetic sheet improves structural stability. 16Two magnetic sheets 16 are arranged to reduce interference with other camera elements. Naturally, three or four magnetic sheets 16 may be present, and these may be arranged based on the specific structure. This is not limited to the foregoing.

[0080] In one particular embodiment, as shown in Figures 3, 14, and 15, the image stabilization mechanism 1 further includes a position detection sensor 15. The position detection sensor is located on a third fixed frame 13 and is configured to detect changes in the magnetic field of the magnet 2 and to provide feedback on the positions of the first movable frame 11 and the second movable frame 12. The position detection sensor 15 is a Hall element or a tunnel magnetoresistance sensor.

[0081] In this embodiment, as shown in Figures 3, 14, and 15, the position detection sensor 15 detects the magnetic field and determines the movement position of the magnet 2 by detecting the change in the magnetic field of the magnet 2, thereby determining the movement positions of the first movable frame 11 and the second movable frame 12, and can provide real-time positional changes of the first movable frame 11 and the second movable frame 12 as feedback. Therefore, the camera module 10 can control the magnitude of the current in the coil 14 based on the real-time positional changes of the first movable frame 11 and the second movable frame 12. In this way, closed-loop control of the positions of the first movable frame 11 and the second movable frame 12 is performed by driving the magnet 2, further improving the control accuracy of the first movable frame 11 and the second movable frame 12.

[0082] Both Hall elements and tunnel magnetoresistance sensors can detect magnetic fields and have the advantages of a simple structure, small size, fast feedback speed, and low cost. If the position detection sensor 15 is a Hall element or a tunnel magnetoresistance sensor, the space occupied by the position detection sensor 15 within the camera module 10 can be reduced. This promotes a compact design for the camera module 10.

[0083] In addition, as shown in Figure 15, the position detection sensor 15 may be placed near the coil 14 to improve the detection efficiency of the position detection sensor 15. Furthermore, two position detection sensors 15 may be placed to improve detection accuracy by detecting movement along the first direction X and the second direction Y, respectively.

[0084] In one particular embodiment, as shown in Figures 1 and 2, the camera module 10 further includes an autofocus mechanism 3. The autofocus mechanism 3 is configured to implement autofocus for the camera module 10. The autofocus mechanism 3 is located on the side of the first movable frame 11 that is away from the second movable frame 12.

[0085] In this embodiment, as shown in Figures 1 and 2, the autofocus mechanism 3 is positioned so that the camera module 10 can implement autofocus while also implementing image stabilization. Therefore, the photographic effect of the electronic device in multiple motion modes is ensured, and the user experience is improved.

[0086] The camera module 10 further includes a lens bracket 32. The lens bracket 32 ​​is mounted on a first movable frame 11, and the lens assembly is mounted on the first movable frame 11 through the lens bracket 32.

[0087] In one particular embodiment, as shown in Figures 2, 16, and 17, the autofocus mechanism 3 includes a focus coil 31. The focus coil 31 is located inside the magnet 2 and is either a single annular coil or formed by combining multiple coils.

[0088] In this embodiment, as shown in Figure 2, when the autofocus mechanism 3 is operating, the focus coil 31 is energized and generates a magnetic flux, which acts on the magnet 2 to drive the autofocus mechanism 3, thereby implementing the autofocus function.

[0089] The focus coil 31 is sleeved on the lens bracket 32, and therefore the focus coil 31 drives the lens bracket 32 ​​to move the lens assembly, thereby enabling autofocus.

[0090] Depending on the specific structure and usage scenario of the camera module 10, the magnets 2, focus coil 31, and image stabilization coil 14 may have different layouts, as shown in Figures 16 and 17. In one particular embodiment shown in Figure 16, there are four magnets 2. The magnets 2 use a single-sided monopole configuration, the focus coil 31 is an integrated annular coil located inside the magnet 2, and the image stabilization coil 14 is located at the bottom of the magnet 2. This structure has the advantages of being simple in structure, having a small number of components, and being highly structurally compact. This facilitates the compact design of the electronic device and the camera module 10. In another particular embodiment shown in Figure 17, there are eight magnets 2. The magnets use a single-sided bipolar configuration, the focus coil 31 is formed by using a combination of four coils and is located inside the magnet 2, and the image stabilization coil 14 is located at the bottom of the magnet 2. In this structure, current control can be performed separately for the four coils forming the focus coil 31, thus the control becomes more precise and the control accuracy is improved.

[0091] Naturally, the magnet 2, the focus coil 31, and the image stabilization coil 14 may be arranged in a different manner, but this is not limited to the foregoing.

[0092] In addition, the autofocus mechanism 3 further includes a focus circuit board assembly 33, and thus the electronic device can implement the autofocus function of the electronic device by supplying power to the focus coil 31 through the focus circuit board assembly 33.

[0093] Embodiments of this application further provide an electronic device including a housing and a camera module 10 in any one of the embodiments described above. The camera module 10 is mounted within the housing.
