Furthermore, in the description and claims, "and/or" means at least one of the connected objects, and the character "/", generally means that the associated object is an "or" relationship.
The camera module provided in the embodiment of the present application is described in detail below by means of specific embodiments and application scenarios thereof with reference to the accompanying drawings.
As shown in fig. 1 to 15, the embodiment of the present application provides a camera module, which includes a module housing 100, a photosensitive chip 200, a lens module 300, a first lens barrel 400, and a first lens 401.
The lens module 300 is disposed opposite to the photosensitive chip 200 and is disposed in the module housing 100. The camera module further includes a circuit board 840, and the photosensitive chip 200 may be disposed on the circuit board 840. In addition, the light sensing chip 200 may be used to receive the light incident from the lens module 300 and finally convert the light signal into a digital image signal, thereby obtaining an image.
The first lens barrel 400 is movably disposed on the module housing 100, the first lens 401 is disposed on the first lens barrel 400, the first lens 401 is disposed opposite to the lens module 300, and the first lens 401 can move along the optical axis direction of the lens module 300 along with the first lens barrel 400. According to the requirement of image capturing, the first lens barrel 400 can drive the first lens 401 to move along the optical axis direction of the lens module 300 in a direction away from the photosensitive chip 200, and can also move along the optical axis direction of the lens module 300 in a direction close to the photosensitive chip 200.
The lens module 300 includes a second lens 310 and a lens holder 320, the second lens 310 is disposed on the lens holder 320, and the second lens 310 and the first lens 401 are sequentially disposed in an optical axis direction of the lens module 300. The second lens 310 and the first lens 401 may cooperate with each other to change the propagation direction of light.
In this embodiment of the present application, the first lens 401 may move along the optical axis direction of the lens module 300 along with the first lens barrel 400, and external light may be incident from the first lens 401 and then pass through the second lens 310, and may be finally received by the photosensitive chip 200, so when a user shoots a near scene, the first lens barrel 400 may be hidden in the module housing 100, and when a user shoots a far scene, the first lens barrel 400 may be exposed outside the module housing 100, thereby implementing the zoom function of the camera module. Because the first lens 401 can move to realize zooming, a single first lens 401 can be suitable for different application scenes, so that the electronic equipment can meet the use requirements of users in different scenes through fewer lenses, and the problem that the camera module occupies a larger space of the electronic equipment can be solved.
In an alternative embodiment, in order to enable the camera module to have a larger zoom range, the camera module may further include a second lens barrel 600, where the second lens barrel 600 is movably disposed in the module housing 100, and the first lens barrel 400 is sleeved in the second lens barrel 600. Since the second lens barrel 600 is movably disposed on the module housing 100, and the first lens barrel 400 is movably sleeved on the second lens barrel 600, the first lens 401 can be further away from the photosensitive chip 200 under the action of the first lens barrel 400 and the second lens barrel 600, so that the range of variation of the distance between the first lens 401 and the photosensitive chip 200 is larger, the zoom range of the camera module is larger, and the zoom effect of the camera module can be improved.
In a further alternative embodiment, in order to implement the continuous zooming function of the camera module, the camera module further includes a zooming driving mechanism 500, where the zooming driving mechanism 500 includes a zooming driving source 510, a first transmission member 520 and a second transmission member 530, the first transmission member 520 is connected to the zooming driving source 510, the second transmission member 530 is connected to the first transmission member 520, and the zooming driving source 510 can drive the first transmission member 520 and the second transmission member 530 to rotate; one of the first transmission member 520 and the second lens barrel 600 is provided with a first spiral guiding structure 521, the other is provided with a first matching protrusion 601, and the second lens barrel 600 can move along with the matching of the first matching protrusion 601 and the first spiral guiding structure 521; one of the second transmission member 530 and the first lens barrel 400 is provided with a second spiral guiding structure 531, the other is provided with a second fitting protrusion 402, and the first lens barrel 400 can move along with the fitting of the second fitting protrusion 402 and the second spiral guiding structure 531.
In one embodiment, the first transmission member 520 is provided with a first spiral guiding structure 521, the second lens barrel 600 is provided with a first matching protrusion 601, after the zoom driving source 510 is started, the zoom driving source 510 drives the first transmission member 520 to rotate, at this time, the first matching protrusion 601 on the second lens barrel 600 is matched with the first spiral guiding structure 521 on the first transmission member 520 to generate relative movement, so as to drive the second lens barrel 600 to approach or separate from the photosensitive chip 200. That is, the second lens barrel 600 may be gradually hidden or gradually exposed out of the module case 100, so that a continuous zoom function of the camera module may be achieved. Alternatively, the first transmission member 520 is provided with a first engaging protrusion 601, the second lens barrel 600 is provided with a first spiral guiding structure 521, after the zoom driving source 510 is started, the zoom driving source 510 drives the first transmission member 520 to rotate, at this time, the first engaging protrusion 601 on the first transmission member 520 is engaged with the first spiral guiding structure 521 on the second lens barrel 600 to generate relative movement, so as to drive the second lens barrel 600 to approach or separate from the photosensitive chip 200. That is, the second lens barrel 600 may be gradually hidden or gradually exposed out of the module case 100, so that a continuous zoom function of the camera module may be achieved. The scheme for realizing continuous zooming can enable the zooming process of the camera module to be more coherent, so that the focal length of the camera module is more diversified, and the camera module can be used in more scenes.
Similarly, the second transmission member 530 is provided with a second spiral guiding structure 531, the first lens barrel 400 is provided with a second matching protrusion 402, after the zoom driving source 510 is started, the zoom driving source 510 drives the first transmission member 520 to rotate, and the first transmission member 520 drives the second transmission member 530 to rotate, at this time, the second matching protrusion 402 on the first lens barrel 400 and the second spiral guiding structure 531 on the second transmission member 530 are matched to generate relative movement, so as to drive the first lens barrel 400 to approach or separate from the photosensitive chip 200. That is, the first barrel 400 may be gradually hidden or gradually exposed to the second barrel 600, so that a continuous zoom function of the camera module may be realized; or, the second transmission member 530 is provided with the second matching protrusion 402, the first lens barrel 400 is provided with the second spiral guiding structure 531, after the zoom driving source 510 is started, the zoom driving source 510 drives the first transmission member 520 to rotate, and the first transmission member 520 drives the second transmission member 530 to rotate, at this time, the second matching protrusion 402 on the second transmission member 530 and the second spiral guiding structure 531 on the first lens barrel 400 are matched to generate relative movement, so as to drive the first lens barrel 400 to approach or separate from the photosensitive chip 200. That is, the first barrel 400 may be gradually hidden or gradually exposed to the second barrel 600, so that a continuous zoom function of the camera module may be realized.
In summary, by the above manner, the second lens barrel 600 can be hidden in the module housing 100 while the camera module continuous zooming function is realized, and the first lens barrel 400 can also be retracted into the second lens barrel 600, so as to achieve the purpose of being hidden in the module housing 100, therefore, when the user finishes shooting, the volume of the whole camera module can be smaller by retracting the first lens barrel 400 and the second lens barrel 600, which is beneficial to reducing the volume of the whole electronic device.
In one embodiment, one of the first transmission member 520 and the second transmission member 530 is provided with a third spiral guiding structure 522, and the other is provided with a third engaging protrusion 532, and the second transmission member 530 can move and rotate along with the engagement of the third engaging protrusion 532 with the third spiral guiding structure 522. In one embodiment, the first transmission member 520 is provided with a third spiral guiding structure 522, the second transmission member 530 is provided with a third matching protrusion 532, and when the first transmission member 520 rotates under the condition that the third spiral guiding structure 522 on the first transmission member 520 is matched with the third matching protrusion 532 on the second transmission member 530, the second transmission member 530 moves and rotates along with the first transmission member 520, and the second transmission member 530 can gradually extend or gradually retract into the first transmission member 520. In another embodiment, the first transmission member 520 is provided with a third engaging protrusion 532, the second transmission member 530 is provided with a third spiral guiding structure 522, and when the first transmission member 520 rotates, the second transmission member 530 moves and rotates along with the third engaging protrusion 532 on the first transmission member 520 and the second transmission member 530 can gradually extend or gradually retract into the first transmission member 520 under the condition that the third engaging protrusion 532 on the first transmission member 520 is engaged with the third spiral guiding structure 522 on the second transmission member 530. When the second transmission member 530 gradually extends out of the first transmission member 520, the zooming function of the camera module can be realized; when the second transmission member 530 gradually contracts to the first transmission member 520, not only the zooming function of the camera module can be achieved, but also miniaturization of the camera module can be facilitated.
In an alternative embodiment, the zoom driving source 510 is a zoom motor, the first transmission member 520 is provided with a first driving gear 523, the zoom driving mechanism 500 further includes a first transmission gear 540, the first transmission gear 540 is meshed with the first driving gear 523, and the zoom motor drives the first transmission member 520 to rotate through the first transmission gear 540. After the zoom motor is started, the zoom motor may drive the first transmission gear 540 to rotate, and since the first transmission gear 540 is meshed with the first driving gear 523, the first transmission gear 540 may drive the first driving gear 523 to rotate, so that the first transmission member 520 may be driven to rotate. The first transmission member 520 and the second transmission member 530 can be more smoothly transmitted by the zoom motor, the first transmission gear 540, and the first driving gear 523. In another embodiment, the zoom driving mechanism 500 may further include a worm and gear assembly, and the zoom driving mechanism 500 may transmit the power of the zoom driving mechanism 500 to the first transmission member 520 through the worm and gear assembly, so that the power transmission between the zoom motor and the first transmission member 520 may be achieved. The worm and gear assembly is adopted, so that the transmission shaft of the zoom motor and the worm are not in the same plane, and the layout of the zoom motor is facilitated.
During image capturing, if the camera module shakes, the light passing through the first lens 401, the third lens 820 and the second lens 310 deviates from the original light path, so that the captured image is blurred. Therefore, in another alternative embodiment, in order to implement the anti-shake function of the camera module, the camera module further includes an anti-shake driving mechanism 700 and a third lens 820, where the third lens 820 is movably disposed in the first lens barrel 400, the anti-shake driving mechanism 700 is connected to the third lens 820, and the anti-shake driving mechanism 700 can drive the third lens 820 to move along a direction parallel to the photosensitive chip 200. At this time, the anti-shake driving mechanism 700 drives the third lens 820 to move along the direction parallel to the photosensitive chip 200 according to the shake direction and the displacement of the camera module, so that the third lens 820 is at a proper position and angle, and the light path is kept stable, so that the problem of image blurring caused by shake of the camera module can be effectively overcome.
In a further alternative embodiment, the camera module further includes a third transmission member 810, the third lens 820 is disposed on the third transmission member 810, one of the third transmission member 810 and the second transmission member 530 is provided with a fourth spiral guiding structure 533, the other is provided with a fourth mating protrusion 811, and the third transmission member 810 can be close to or far from the photosensitive chip 200 along with the mating of the fourth mating protrusion 811 and the fourth spiral guiding structure 533. In one embodiment, the third driving member 810 is provided with a fourth mating protrusion 811, the second driving member 530 is provided with a fourth spiral guiding structure 533, and when the second driving member 530 rotates, the fourth mating protrusion 811 on the third driving member 810 mates with the fourth spiral guiding structure 533 on the second driving member 530, so that the third driving member 810 approaches or departs from the photosensitive chip 200, and the third lens 820 can be mated with the first lens 401 to improve the continuous zooming effect of the camera module; in another embodiment, the third driving member 810 is provided with a fourth spiral guiding structure 533, the second driving member 530 is provided with a fourth mating protrusion 811, and when the second driving member 530 rotates, the fourth mating protrusion 811 on the second driving member 530 mates with the fourth spiral guiding structure 533 on the third driving member 810, so that the third driving member 810 is close to or far from the photosensitive chip 200, and the third lens 820 can be mated with the first lens 401 to improve the continuous zooming effect of the camera module. In summary, by the engagement of the fourth engagement protrusion 811 with the fourth spiral guiding structure 533, the displacement of the third lens 820 can be changed in the direction parallel to the optical axis, so that the continuous zooming effect of the camera module can be further improved.
In one embodiment, the helix angle of the fourth helical guide 533 is greater than the helix angle of the second helical guide 531. In this embodiment, when the electronic device shakes, the third lens 820 can change the position of the third lens 820 under the driving of the third driving member 810, so as to achieve the purpose of compensating the optical path. However, the helix angle of the fourth spiral guide 533 is relatively too large, so that the displacement of the third lens 820 is large when the third lens 820 is adjusted, resulting in lower accuracy when the displacement of the third lens 820 is adjusted, and thus poor optical path compensation. Therefore, the helix angle of the fourth helical guide 533 is smaller than the helix angle of the second helical guide 531. Under the same adjustment conditions as in the above embodiments, when the third lens 820 moves along with the third transmission member 810, the movement amount of the third lens 820 is smaller, so that fine adjustment of the third lens 820 can be achieved by a smaller spiral angle, and in addition, the risk of collision of the third lens 820 with the first lens 401 due to excessive displacement can be prevented.
In another embodiment, the anti-shake driving mechanism 700 may include an electromagnetic member and a magnetic member, and the anti-shake function of the camera module may be achieved by changing the magnitude of the attractive force and the repulsive force between the electromagnetic member and the magnetic member, and changing the direction of the attractive force and the repulsive force. However, the interaction of the electromagnetic member and the magnetic member may create magnetic interference that may cause other components of the electronic device to fail to function properly. Therefore, in order to further enhance the anti-shake effect of the camera module, the anti-shake driving mechanism 700 may further include a fourth shape memory member 740, where the first shape memory member 710, the second shape memory member 720, the third shape memory member 730 and the fourth shape memory member 740 are all connected between the third transmission member 810 and the third lens 820, and the four members are arranged in a quadrilateral manner. In this embodiment, the anti-shake driving mechanism 700 can pull the third lens 820 in four directions, so that the direction of the optical path compensation is more and the effect is better. In addition, the displacement of the third lens 820 in the direction perpendicular to the optical axis can be changed by using the first shape memory element 710, the second shape memory element 720, the third shape memory element 730 and the fourth shape memory element 740, so that the anti-shake effect of the camera module can be further improved.
In one embodiment, in order to implement the focusing function of the camera module, the camera module further includes a focusing driving mechanism 900, the focusing driving mechanism 900 is connected to the lens module 300, and the focusing driving mechanism 900 can drive the lens module 300 to approach or separate from the photosensitive chip 200. When an image is captured, if the image frame is blurred, the focusing driving mechanism 900 can drive the lens module 300 to drive the second lens 310 to approach or separate from the photosensitive chip 200, so that the captured image frame can be clearer.
In a further embodiment, the focusing driving mechanism 900 includes a focusing driving source 910 and a fourth transmission member 920, the fourth transmission member 920 is connected to the focusing driving source 910, and the focusing driving source 910 can drive the fourth transmission member 920 to rotate; one of the fourth transmission member 920 and the lens module 300 is provided with a fifth spiral guiding structure 921, and the other is provided with a fifth mating protrusion 321, and the lens module 300 can move along with the mating of the fifth mating protrusion 321 and the fifth spiral guiding structure 921. In an embodiment, the fourth transmission member 920 is provided with a fifth spiral guiding structure 921, the lens module 300 is provided with a fifth matching protrusion 321, after the focusing driving source 910 is started, the focusing driving source 910 drives the fourth transmission member 920 to rotate, and in the process of rotating the fourth transmission member 920, the fifth matching protrusion 321 on the lens module 300 and the fifth spiral guiding structure 921 on the fourth transmission member 920 are matched to generate relative movement, so that the distance between the lens module 300 and the photosensitive chip 200 can be changed, and the focusing function of the camera module can be realized. In another embodiment, the fourth transmission member 920 is provided with a fifth mating protrusion 321, the lens module 300 is provided with a fifth spiral guiding structure 921, after the focusing driving source 910 is started, the focusing driving source 910 drives the fourth transmission member 920 to rotate, and in the process of rotating the fourth transmission member 920, the fifth mating protrusion 321 on the fourth transmission member 920 and the fifth spiral guiding structure 921 on the lens module 300 are mated to generate relative movement, so that the distance between the lens module 300 and the photosensitive chip 200 can be changed, and the focusing function of the camera module can be realized.
The above-mentioned scheme of achieving the transmission through the cooperation of the first screw guide structure 521 and the first engaging protrusion 601, the second screw guide structure 531 and the second engaging protrusion 402, the third screw guide structure 522 and the third engaging protrusion 532, the fourth screw guide structure 533 and the fourth engaging protrusion 811, and the fifth screw guide structure 921 and the fifth engaging protrusion 321, in other embodiments, the transmission may be achieved through the screw-fit manner between the first transmission member 520 and the second barrel 600, between the second transmission member 530 and the first barrel 400, between the first transmission member 520 and the second transmission member 530, between the third transmission member 810 and the second transmission member 530, and between the fourth transmission member 920 and the lens module 300. However, in this way, the contact area between the parts is large by the screw-fit manner, and the resistance is relatively large, so that a large driving force is required between the parts to realize the change of the relative positions. In contrast, by changing the relative positions of the respective members by the fitting manner of the first screw guide structure 521 and the first fitting projection 601, the second screw guide structure 531 and the second fitting projection 402, the third screw guide structure 522 and the third fitting projection 532, the fourth screw guide structure 533 and the fourth fitting projection 811, and the fifth screw guide structure 921 and the fifth fitting projection 321, the contact area between the respective members can be reduced, so that the resistance between the respective members can be reduced, and further, the change in position between the respective members can be achieved by a relatively small driving force, while also slowing down the wear between the respective members. Alternatively, the first spiral guide structure 521, the second spiral guide structure 531, the third spiral guide structure 522, the fourth spiral guide structure 533, and the fifth spiral guide structure 921 may be spiral grooves or spiral holes, which is not limited in the embodiment of the present application.
In a further alternative embodiment, the focusing driving source 910 is a focusing motor, the fourth driving member 920 is provided with a second driving tooth 922, the focusing driving mechanism 900 further includes a second driving gear 930, the second driving gear 930 is meshed with the second driving tooth 922, and the focusing motor drives the fourth driving member 920 to rotate through the second driving gear 930. After the focusing motor is started, the focusing motor drives the second transmission gear 930 to rotate, and because the second transmission gear 930 is meshed with the second driving gear 922, the second transmission gear 930 can drive the second driving gear 922 to rotate, so that the fourth transmission member 920 can rotate. In this embodiment, the first transmission member 520 and the second transmission member 530 can be driven more smoothly by using the focusing motor, the second transmission gear 930 and the second driving teeth 922. In another embodiment, the focusing driving mechanism 900 may further include a worm and gear assembly, and the focusing driving mechanism 900 may transmit the power of the focusing driving mechanism 900 to the fourth transmission member 920 through the worm and gear assembly, so that the power transmission between the focusing motor and the fourth transmission member 920 may be achieved. The transmission shaft of the focusing motor and the worm are not in the same plane due to the adoption of the worm and gear assembly, so that the layout of the focusing motor is facilitated.
