Description

Technical Field

[0001] This application belongs to the field of camera technology, specifically relating to a camera module and electronic device. Background Technology

[0002] Nowadays, with the continuous improvement of camera technology in electronic devices, people hope to use electronic devices to capture higher quality images. In order to meet users' requirements for shooting quality, the specifications and number of cameras included in electronic devices are constantly increasing. This leads to increasing difficulty in the spatial layout of electronic devices, posing a great challenge to the structural design of electronic devices.

[0003] To reduce the spatial layout complexity of electronic devices, a retractable camera module can be used. The lens of this retractable camera module can extend and retract relative to the housing of the electronic device, allowing the lens to extend out of the housing for high-quality shooting operations, or retract into the housing to store the lens. In addition, this retractable structure can also achieve optical zoom, thus achieving the shooting effect of multiple cameras with a single lens.

[0004] Specifically, the lens can be moved by a drive motor working in conjunction with a transmission mechanism, thus achieving lens extension and retraction. However, the drive motor requires a significant amount of space, and the transmission mechanism contains numerous components that also require considerable space, making the spatial layout of the electronic equipment quite challenging. Furthermore, the drive motor, transmission mechanism, and their constituent parts utilize a contact-type transmission method, which suffers from high losses and poor adjustment flexibility. Summary of the Invention

[0005] The purpose of this application is to provide a camera module and electronic device that can solve the problems of difficult spatial layout, large transmission loss and poor adjustment flexibility of electronic devices.

[0006] To solve the above-mentioned technical problems, this application is implemented as follows:

[0007] In a first aspect, embodiments of this application provide a camera module, which includes a base, a lens, a rotating bracket, a drive coil, and a drive magnet, wherein...

[0008] The rotating bracket is rotatably connected to the base, and the lens is connected to the rotating bracket. One of the base and the rotating bracket is provided with the driving coil, and the other is provided with the driving magnet. When the driving coil and the driving magnet interact, the rotating bracket rotates along the direction surrounding the optical axis of the lens, thereby driving the lens to move along the direction of the optical axis.

[0009] Secondly, embodiments of this application provide an electronic device that includes the aforementioned camera module.

[0010] In this embodiment, when the driving coil and driving magnet interact, the rotating bracket rotates along the optical axis surrounding the lens, thereby moving the lens along the optical axis. In other words, the magnetic force between the driving coil and driving magnet drives the rotating bracket to rotate, which in turn moves the lens, changing its position relative to the photosensitive chip. This solution largely eliminates the need for complex components to work with the driving coil and driving magnet for transmission. Furthermore, the non-contact transmission between the driving coil and driving magnet results in lower transmission losses and greater flexibility in adjusting the positions of the driving coil and driving magnet. Therefore, this solution effectively addresses the problems of complex spatial layout, high transmission losses, and poor adjustment flexibility in electronic devices. Attached Figure Description

[0026] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0027] The terms "first," "second," etc., used in the specification and claims of this application are used to distinguish similar objects and not to describe a specific order or sequence. It should be understood that such use of data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0028] The camera module and electronic device provided in this application will be described in detail below with reference to the accompanying drawings, through specific embodiments and application scenarios.

[0029] like Figures 1 to 9 As shown in the figure, this application discloses a camera module, which includes a base 100, a photosensitive chip, a lens 200, a rotating bracket 300, a driving coil, and a driving magnet.

[0030] A photosensitive chip is mounted on the base 100. Besides the photosensitive chip, the base 100 can also house other components of the camera module. A rotating bracket 300 is rotatably connected to the base 100, meaning the rotating bracket 300 can rotate relative to the base 100. The lens 200 is connected to the rotating bracket 300. When the rotating bracket 300 moves, it can move the lens 200, allowing the lens 200 to change the direction of light propagation. The photosensitive chip can receive the light passing through the lens 200 and ultimately convert the light signal into a digital image signal, thus obtaining an image. Optionally, the rotating bracket 300 can have a cylindrical structure, allowing the lens 200 to be retracted and thus protected.

[0031] In the base 100 and the rotating bracket 300, one is equipped with a drive coil, and the other with a drive magnet. When the drive coil interacts with the drive magnet, the rotating bracket 300 rotates along the optical axis surrounding the lens 200, thereby moving the lens 200 along the optical axis. When the drive coil is energized, it generates a magnetic field. This magnetic field interacts with the magnetic field of the drive magnet to produce an Ampere force, which can manifest as magnetic attraction or repulsion. Under the action of the Ampere force, the rotating bracket 300 can rotate relative to the base 100, thereby moving the lens 200 towards or away from the photosensitive chip, thus changing the position of the lens 200 relative to the photosensitive chip. By precisely controlling the current applied to the drive coil, the amount of movement of the lens 200 can be precisely controlled, thereby precisely controlling the zoom level of the camera module.

[0032] When using a drive coil and a drive magnet to output driving force, there is virtually no need for complex components to work with the drive coil and magnet to achieve transmission. Furthermore, the drive coil and magnet achieve transmission in a non-contact manner, resulting in lower transmission losses and greater flexibility in adjusting their positions. Therefore, this solution effectively addresses the problems of complex spatial layout, high transmission losses, and poor adjustment flexibility in electronic devices. In addition, since the drive coil and magnet do not need to contact to drive the lens 200, the wear between them is minimal, leading to a longer service life.

[0033] As mentioned above, the rotating bracket 300 rotates along the optical axis surrounding the lens 200, which can drive the lens 200 to move along the optical axis. To achieve this, in one optional embodiment, one of the rotating bracket 300 and the lens 200 is provided with a helical guide groove, and the other is provided with a mating protrusion. The mating protrusion can engage with the helical guide groove. When the rotating bracket 300 rotates, the lens 200 moves accordingly under the action of the helical guide groove and the mating protrusion, thereby changing the distance between the lens 200 and the photosensitive chip. In another optional embodiment, a lead screw and a slider can be provided inside the rotating bracket 300. The lead screw is connected to the rotating bracket 300 via a transmission gear, and the slider is threadedly engaged with the lead screw and fixedly connected to the lens 200. When the rotating bracket 300 rotates, it can drive the lead screw to rotate, which in turn drives the slider to move, and the slider then drives the lens 200 to move. Relatively speaking, the structure of the former embodiment is simpler and requires fewer components, resulting in a smaller space occupied by the camera module.

[0034] The number of driving magnets can be one or at least two. In an optional embodiment, the number of driving magnets is at least two, including a first magnet 410 and a second magnet 420. Both the first magnet 410 and the second magnet 420 are disposed on the rotating bracket 300. In this case, the first magnet 410 and the second magnet 420 can be arranged at intervals along the rotation direction of the rotating bracket 300. The first magnet 410 can be correspondingly disposed with the first coil group 510, and the second magnet 420 can be correspondingly disposed with the second coil group 520. Here, both the first coil group 510 and the second coil group 520 include at least one driving coil. In this embodiment, the number of driving magnets and driving coils is at least two, so the magnetic force formed by the two can be greater, thereby driving the rotating bracket 300 to rotate more reliably. At the same time, the magnetic field coverage of the driving magnets and driving coils is larger, thereby increasing the rotation range of the rotating bracket 300, and thus increasing the zoom range of the lens 200. Furthermore, the force formed between the first magnet 410 and the first coil group 510, and the force formed between the second magnet 420 and the second coil group 520, can be used to realize the rotation of the rotating bracket 300 within different ranges, thus enabling the rotating bracket 300 to rotate within a larger range of rotation using fewer drive coils.

[0035] All the drive coils included in the first coil group 510 can be arranged toward the outer peripheral surface of the rotating bracket 300, that is, the axes of these drive coils can extend approximately radially along the rotating bracket 300. However, in this way, the magnetic field interaction range between the drive coils and the drive magnet is small, resulting in insufficient force between them. Therefore, in other embodiments, the first coil group 510 includes a first coil 511, and the second coil group 520 includes a second coil 521. The first coil 511 and the second coil 521 are spaced apart along a direction surrounding the optical axis, and the first magnet 410 and the second magnet 420 can move within the space between the first coil 511 and the second coil 521. When the rotating bracket 300 is in a first position, the first magnet 410 is opposite to the first coil 511, and there is a first included angle between the first magnet 410 and the first coil 511. Optionally, in this state, the second magnet 420 may be opposite to another drive coil, or it may not be opposite to any drive coil. With the rotating support 300 in the second position, the second magnet 420 is opposite to the second coil 521, and there is a second included angle between the second magnet 420 and the second coil 521. Optionally, in this state, the first magnet 410 may be opposite to another drive coil, or it may not be opposite to any drive coil. Optionally, both the first and second included angles can be 0° to 60°.

[0036] The first coil 511 and the second coil 521 can determine the extreme positions of the rotating bracket 300 during rotation. The axis of the first coil 511 and the second coil 521 is basically in the same direction as the rotation direction of the rotating bracket 300. The plane containing the first coil 511 and the second coil 521 can be coplanar with the radial plane of the rotating bracket 300, or it can form a small angle with the radial plane of the rotating bracket 300, thereby allowing the driving magnet to move in the region where the magnetic field strength of the magnetic field formed by the driving coil is large, thus increasing the generated magnetic force. Optionally, the driving magnet has a first end and a second end. The first end is connected to the rotating bracket 300, and the second end is away from the rotating bracket 300. The second end has an end face, and the driving magnet also has a side face connected to the end face. The first coil 511 and the second coil 521 can be opposite to this side face.

[0037] Of course, in other embodiments, only one of the first coil 511 and the second coil 521 can be provided. Such a configuration can also increase the magnetic force, but the increase in magnetic force is not as great as that of providing both the first coil 511 and the second coil 521 at the same time.

[0038] In a further optional embodiment, the first coil group 510 further includes a third coil 512, and the second coil group 520 further includes a fourth coil 522. The third coil 512 and the fourth coil 522 are arranged at intervals along the direction surrounding the optical axis. When the rotating support 300 is in the third position, the first magnet 410 is opposite to the third coil 512, and the second magnet 420 is opposite to the fourth coil 522. When the rotating support 300 is in the third position, the distance between the first magnet 410 and the first coil 511 is relatively large, and at the same time, the distance between the second magnet 420 and the second coil 521 is also relatively large. Therefore, the force formed between the first magnet 410 and the first coil 511, and between the second magnet 420 and the second coil 521, is relatively small. The addition of the third coil 512 and the fourth coil 522 can increase the force in this case, so that the rotating support 300 can rotate more reliably and stably.

[0039] Of course, in other embodiments, only one of the third coil 512 and the fourth coil 522 can be provided. Such a configuration can also increase the magnetic force, but the increase in magnetic force is not as great as that of providing both the third coil 512 and the fourth coil 522 at the same time.

[0040] Furthermore, the first coil group 510 also includes a fifth coil 513, and the second coil group 520 also includes a sixth coil 523. The fifth coil 513 is located between the first coil 511 and the third coil 512, and the sixth coil 523 is located between the second coil 521 and the fourth coil 522. When the rotating support 300 is in the fourth position, the first magnet 410 is opposite to the fifth coil 513. Optionally, in this state, the second magnet 420 may be opposite to another drive coil or not opposite to any drive coil. When the rotating support 300 is in the fifth position, the second magnet 420 is opposite to the sixth coil 523. Optionally, in this state, the first magnet 410 may be opposite to another drive coil or not opposite to any drive coil. With the addition of the fifth coil 513 and the sixth coil 523, the magnetic force on the first magnet 410 and the second magnet 420 is more continuous and greater, thereby enabling the rotating support 300 to rotate more reliably and stably.

[0041] Of course, in other embodiments, only one of the fifth coil 513 and the sixth coil 523 can be set. Such a setting can also increase the magnetic force, but the increase in magnetic force is not as great as that of setting the third coil 512 and the fourth coil 522 at the same time.

[0042] Furthermore, the axes of the aforementioned third coil 512, fourth coil 522, fifth coil 513, and sixth coil 523 can extend approximately along the radial direction of the rotating support 300, or the axes can have a small angle with the radial direction of the rotating support 300. Optionally, the driving magnet has a first end and a second end. The first end is connected to the rotating support 300, and the second end is away from the rotating support 300 and has an end face. The third coil 512, fourth coil 522, fifth coil 513, and sixth coil 523 can be opposite to this end face. The third coil 512, fourth coil 522, fifth coil 513, and sixth coil 523 can form a large magnetic force with the first magnet 410 and the second magnet 420 without affecting the rotation of the rotating support 300. Moreover, more driving coils can be provided to increase the magnetic force between the driving magnet and the driving coils, and to expand the range of motion of the driving magnet. This application embodiment does not limit this.

[0043] When the camera module includes the first coil 511, the second coil 521, the third coil 512, the fourth coil 522, the fifth coil 513, and the sixth coil 523 mentioned above, the zoom process of the camera module can be described as follows:

[0044] like Figure 5 As shown, when the camera module is in its initial state, the rotating bracket 300 can be in the first position. At this time, the first magnet 410 is simultaneously subjected to the magnetic repulsion of the first coil 511 and the magnetic attraction of the fifth coil 513, causing the rotating bracket 300 to rotate clockwise. Figure 6 The fourth position is shown. Since the first magnet 410 moves away from the first coil 511 after the rotating bracket 300 reaches the fourth position, the thrust provided by the first coil 511 decreases. Therefore, at the fourth position, the rotating bracket 300 rotates due to the magnetic attraction of the third coil 512 on the first magnet 410 and the magnetic attraction of the fourth coil 522 on the second magnet 420. Figure 7 The third position is shown. Afterwards, the rotating bracket 300 can rotate to the third position by the magnetic repulsion of the fifth coil 513 on the first magnet 410 and the magnetic attraction of the sixth coil 523 on the second magnet 420. Figure 8 The fifth position is shown. Afterwards, the magnetic repulsion of the third coil 512 on the first magnet 410, the magnetic repulsion of the fourth coil 522 on the second magnet 420, and the magnetic attraction of the second coil 521 on the second magnet 420 can jointly drive the rotating support 300 to reach... Figure 9 The second position is shown. The process of returning from the second position to the first position is the reverse of the above process, with the direction of the force reversed, and will not be described again here. Of course, the form of magnetic force generated during the rotation of the rotating bracket 300 is not limited to the method described here, and other combinations can be used. This application embodiment does not limit this.

[0045] The third coil 512, the fourth coil 522, the fifth coil 513, and the sixth coil 523 can all be planar coils, meaning the surface on which these coils are located can be planar. However, to increase the magnetic force formed between the driving coil and the driving magnet, at least one of the third coil 512, the fourth coil 522, the fifth coil 513, and the sixth coil 523 can be configured as a bent coil, with the bent coil bent towards the side of the optical axis. Optionally, in the radial direction of the rotating support 300, the bend at the optical axis is opposite to the optical axis, and the bent coil can adopt a V-shaped bend structure. In the magnetic field formed by the bent coil, the portion located between the bent coil and the rotating support 300 has an outward expansion distribution, thereby making the distribution range of this part of the magnetic field wider, while optimizing the consistency of the magnetic field distribution between the driving magnet and the driving coil, thus achieving the purpose of increasing the magnetic force.

[0046] The drive coil can be mounted on the base 100 via the mounting piece 710. If the aforementioned bent coil is used, the mounting piece 710 corresponding to the bent coil can have a bent mounting surface, thereby achieving reliable fixation of the bent coil. In this case, a single integrated mounting piece 710 can be used to mount all drive coils simultaneously, or multiple separately mounted pieces 710 can be used to mount each drive coil separately. Relatively speaking, the multiple separately mounted pieces 710 can be discretely distributed, and the size of each mounting piece 710 can be set as small as possible while meeting installation requirements. Therefore, the overall space occupied by each mounting piece 710 and the overall weight are relatively small, which is more conducive to improving the space utilization of the camera module and reducing the weight of the camera module.

[0047] like Figures 10 to 15 As shown, in an optional embodiment, the first coil group 510 includes at least two seventh coils 514, and the second coil group 520 includes at least two eighth coils 524. Each seventh coil 514 and each eighth coil 524 is spaced apart along the direction surrounding the optical axis. Each seventh coil 514 and each eighth coil 524 can form a magnetic field with the driving magnet more continuously, thereby enabling the rotating bracket 300 to rotate more reliably and smoothly. During the rotation of the rotating bracket 300, in the direction of movement of the first magnet 410, the driving coil located in front of the first magnet 410 provides magnetic attraction, and the driving coil located behind the first magnet 410 provides magnetic repulsion, thereby driving the rotating bracket 300.

[0048] During the rotation of the rotating support 300, the first magnet 410 and the second magnet 420 alternate between being opposite to the drive coil and being opposite to the adjacent drive coil at intervals. If the first magnet 410 is opposite to the seventh coil 514 while the second magnet 420 is opposite to the eighth coil 524, the magnetic forces experienced by both magnets 410 and 420 are relatively large. However, if the intervals between the first magnet 410 and the adjacent seventh coil 514 are opposite while the intervals between the second magnet 420 and the adjacent eighth coil 524 are opposite, the magnetic forces experienced by both magnets 410 and 420 are relatively small. This results in unstable forces acting on the rotating support 300. Therefore, in optional embodiments, when the first magnet 410 is opposite to the seventh coil 514, the interval between the second magnet 420 and the adjacent eighth coil 524 is opposite; or, when the interval between the first magnet 410 and the adjacent seventh coil 514 is opposite, the second magnet 420 is opposite to the eighth coil 524. Of course, both situations can occur simultaneously in the same embodiment. This approach allows for a combination of a state where the first magnet 410 experiences a greater force and a state where the second magnet 420 experiences a lesser force, or vice versa. This prevents sudden changes in the force acting on the rotating support 300 during rotation, thus enabling the rotating support 300 to rotate more stably.

[0049] When the first coil group 510 includes both the first coil 511 and the seventh coil 514, and the second coil group 520 includes both the second coil 521 and the eighth coil 524, the camera module may further optionally include a coil bracket. The coil bracket is disposed on the base 100 and includes a first flat plate 610, an arc plate 630, and a second flat plate 620 connected in sequence. Both the first flat plate 610 and the second flat plate 620 are bent relative to the arc plate 630. The center of the circumference of the arc plate 630 is located on the rotation axis of the rotating bracket 300. The first coil 511 is attached to the first flat plate 610, the second coil 521 is attached to the second flat plate 620, and the seventh coil 514 and the eighth coil 524 are both attached to the side of the arc plate 630 facing the rotating bracket 300. This embodiment uses the same coil bracket to simultaneously install the first coil 511, the second coil 521, the seventh coil 514, and the eighth coil 524, which facilitates the assembly of the camera module. At the same time, the arc plate 630 can provide a large area, which makes it easy to adjust the number of the seventh coil 514 and the eighth coil 524 according to actual needs. Therefore, this structure is more convenient for the structural design of the camera module.

[0050] In one embodiment, such as Figure 2 and Figure 3As shown, the driving magnet has a first magnetic pole and a second magnetic pole, which are distributed along a direction surrounding the optical axis. In another embodiment, as... Figure 11 and Figure 12 As shown, the driving magnet also has a first magnetic pole and a second magnetic pole, which are distributed along a direction perpendicular to the optical axis, i.e., the first magnetic pole and the second magnetic pole are distributed radially along the rotating support 300. The first magnetic pole can be located on the side of the second magnetic pole away from the optical axis. Optionally, the first magnetic pole can be the S pole and the second magnetic pole can be the N pole. Relatively speaking, in the latter embodiment, the relative position change between the magnetic field of the driving magnet and the magnetic field generated by the driving coil is simpler during the rotation of the rotating support 300, and the magnetic force generated between the two magnetic fields is greater. Therefore, the latter embodiment can simplify the control of the driving coil and appropriately increase the interaction force between the driving coil and the driving magnet, making the rotating support 300 rotate more reliably and smoothly.

[0051] When the first and second magnetic poles are distributed along the direction surrounding the optical axis, the magnetic force generated between the driving magnet and the driving coil can be increased by setting a bent coil. When the first and second magnetic poles are distributed along the direction perpendicular to the optical axis, since the magnetic force generated between the driving magnet and the driving coil is already large enough in this way, all driving coils can be set as planar coils. Alternatively, when the coil support includes a first plate 610, a second plate 620, and an arc plate 630, the driving coils mounted on the first plate 610 and the second plate 620 can be set as planar coils, and the driving coils mounted on the arc plate 630 can be set as arc coils adapted to the arc plate 630, thereby simplifying the structure of the driving coils and reducing the cost of the camera module.

[0052] Optionally, when there is only one driving magnet, it is mounted on the rotating bracket 300. The number of driving coils is at least two. The camera module also includes a cylindrical bracket mounted on the base 100, surrounding the rotating bracket 300. Each driving coil is attached to the side of the cylindrical bracket facing the rotating bracket 300. In this embodiment, the rotational stability of the rotating bracket 300 mainly depends on the magnetic force experienced by the driving magnet. Therefore, by adjusting the number, position, and current of the driving coils, it is easier to adjust the magnetic force experienced by the driving magnet, thereby making the rotating bracket 300 rotate more stably. Simultaneously, the rotational range of the rotating bracket 300 can be larger; for example, the rotating bracket 300 can rotate one full turn or even more. Therefore, the transmission ratio between the rotating bracket 300 and the lens 200 can be appropriately adjusted so that when the lens 200 moves by the same amount, the rotational range of the rotating bracket 300 is larger, thereby appropriately reducing the rotational speed of the rotating bracket 300 and making its rotation more stable. Optionally, a speed reduction device can be installed between the rotating bracket 300 and the lens 200 to adjust the transmission ratio between them. Alternatively, this solution can also increase the rotation range of the rotating bracket 300 to expand the movement range of the lens 200, thus easily increasing the zoom ratio of the camera module.
