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.
Referring to fig. 1 to 9, an embodiment of the present application discloses a camera module, which is applied to an electronic device, and the disclosed camera module includes a photosensitive chip 500, a main body 400, a first mirror 210 and a second mirror 220.
The photo-sensing chip 500 is used for receiving an optical signal, which can convert the optical signal into image information. The photosensitive surface of the photosensitive chip 500 faces a first direction, which is the optical axis direction of the camera module, and can be understood as the thickness direction of the camera module. Optionally, the photosensitive chip 500 may be a high-resolution photosensitive chip, so that the camera module has better performance, and further the electronic device has better user experience. The photo-sensing chip 500 may be a CMOS (Complementary Metal Oxide Semiconductor ) imaging chip.
The main body 400 is used to provide a mounting base for other components of the camera module. The main body 400 is located at one side of the photosensitive chip 500 in the first direction, and the main body 400 is provided with a first mirror 210, where the first mirror 210 faces the first direction. Alternatively, the first mirror 210 may be attached to the inner surface of the main body 400, or the first mirror 210 is a reflective coating coated in the main body 400, and the specific structure of the first mirror 210 and the main body 400 is not limited herein.
The second mirror 220 is located at one side of the first mirror 210 in the first direction, and the second mirror 220 is movable along the first direction toward the photosensitive chip 500. That is, the moving direction of the second reflecting mirror 220 is along the optical axis direction of the image capturing module. The second mirror 220 is capable of moving in the first direction, so that the distance between the photosensitive chip 500 and the second mirror 220 is changed by moving the second mirror 220, thereby realizing the focusing function of the image capturing module.
In a specific operation process, the ambient light is reflected by the first mirror 210 to the second mirror 220, and then reflected by the second mirror 220 to the light-sensitive chip 500.
In this embodiment of the present application, the second mirror 220 is capable of moving along the first direction, so by moving the second mirror 220, the distance between the photosensitive chip 500 and the second mirror is changed, thereby implementing the focusing function of the image capturing module. In this scheme, light is through twice reflection, in the same thickness space, can effectively prolong the light path, realize the multiple zoom, can reduce the thickness size of the module of making a video recording to reduce the installation space that the module of making a video recording occupy electronic equipment.
In the embodiment disclosed by the application, the quantity of the shooting modules can be set to be one, and the second reflecting mirror 220 is driven to move, so that focusing of the shooting modules is realized, and then the electronic equipment is not required to be provided with a plurality of shooting modules, so that the shooting modules occupy smaller installation space of the electronic equipment, and further the electronic equipment is smaller in size.
In addition, the image capturing module can move the second mirror 220 to a position with a minimum distance from the photosensitive chip 500 when not in use, where the minimum distance is a position with a minimum focal length of the image capturing module. At this time, the volume of the camera module is smaller, so that the camera module occupies a smaller installation space of the electronic equipment, and the electronic equipment is smaller in size, so that the light and thin performance of the electronic equipment is improved, and the user experience can be improved.
In addition, the first reflecting mirror 210 is disposed on the main body 400, so as to compress the volume of the camera module, and further make the thickness of the camera module smaller.
Meanwhile, only one camera module can be arranged, so that only one opening for installing the camera module is arranged on the electronic equipment, and the appearance performance of the electronic equipment is improved.
In the above embodiment, the second reflecting mirror 220 moves away from the photosensitive chip 500, so that the focal length of the camera module can be increased, and the camera module has a longer focal length, so that the shooting performance of the camera module is better. The scheme can enable the camera module to have a longer focal length and enable the camera module to be smaller in size, so that the service performance of the camera module is improved.
In the above embodiment, the side of the main body 400 facing the second mirror 220 may be provided with the telescopic mechanism, and the telescopic mechanism drives the second mirror 220 to move, however, the surface of the side of the main body 400 facing the second mirror 220 needs to be reserved with the installation position of the telescopic mechanism, so that the installation position of the first mirror 210 is compressed, and the effective reflection area of the first mirror 210 is smaller.
Based on this, in another alternative embodiment, the image capturing module disclosed herein may further include a lifting cylinder 300, and the lifting cylinder 300 may be sleeved outside the main body 400. The lift cylinder 300 is movable in a first direction with respect to the main body 400. The second reflecting mirror 220 may be mounted at an end of the lifting cylinder 300 facing away from the first reflecting mirror 210, and the lifting cylinder 300 may drive the second reflecting mirror 220 to move. In this solution, the lifting cylinder 300 is sleeved outside the main body 400, so that the installation space of the main body 400 is not occupied, and the effective reflection area of the first reflecting mirror 210 is larger, so that the reflection effect of the first reflecting mirror 210 is better.
In the above embodiment, the movement of the lifting cylinder 300 may be manually driven by a user, but there is a problem in that the manual operation has low accuracy. Based on this, in another alternative embodiment, the camera module disclosed herein may further include a driving mechanism 600, where the driving mechanism 600 may be disposed on the main body 400, and the driving mechanism 600 may be used to drive the lifting cylinder 300 to move along the first direction, and the lifting cylinder 300 drives the second mirror 220 to move along the first direction. In this embodiment, the driving mechanism 600 can precisely drive the lifting cylinder 300 to move. Meanwhile, the user can trigger the driving mechanism 600 to move in a wireless control manner, so as to drive the lifting cylinder 300 to move, and the focusing operation of the camera module is more convenient to implement.
The lifting cylinder 300 can be driven to move by a plurality of structures capable of achieving corresponding driving functions, such as a pneumatic transmission mechanism or a hydraulic transmission mechanism realized by a piston mechanism, a screw pair transmission mechanism realized by a screw mechanism, a transmission mechanism of a gear rack structure and the like, or the lifting cylinder 300 can be driven to move by adopting a certain shape memory alloy through self shape reset.
In another alternative embodiment, the body part 400 may include a first cylinder 410 and a second cylinder 420, and the first cylinder 410 may be sleeved outside the second cylinder 420. The lifting cylinder 300 may be sleeved outside the first cylinder 410. The first mirror 210 may be located at an end of the second cylinder 420 remote from the second mirror 220.
The driving mechanism 600 may be disposed on the first cylinder 410, the driving mechanism 600 may be connected to the second cylinder 420 and may drive the second cylinder 420 to rotate around its axis, the lifting cylinder 300 may be provided with the fitting protrusion 310, the first cylinder 410 may be provided with the guide hole 411, and the guide hole 411 may extend along the axis direction of the lifting cylinder 300.
The second cylinder 420 may be provided with a spiral guide structure 421, and the engaging protrusion 310 may pass through the guide hole 411 to engage with the spiral guide structure 421, so that the lifting cylinder 300 may move along the extending direction of the guide hole 411 when the driving mechanism 600 may drive the second cylinder 420 to rotate.
For example, when the second reflecting mirror 220 is far away from the photosensitive chip 500, the second cylinder 420 rotates toward the first direction, the spiral guiding structure 421 generates two component forces in the horizontal direction and the vertical direction on the engaging protrusion 310, and the component force in the horizontal direction is offset by the side wall of the guiding hole 411, so that the engaging protrusion 310 cannot rotate along the circumferential direction of the second cylinder 420, and the component force in the vertical direction drives the engaging protrusion 310 to move along the vertical direction, and further drives the lifting cylinder 300 to move along the vertical direction.
When the second reflecting mirror 220 approaches the photosensitive chip 500, the second cylinder 420 rotates in the second direction, and the component force of the second reflecting mirror 220 is the same as the component force of the second reflecting mirror 220 away from the photosensitive chip 500, but the direction of the component force is different. And thus are not described in detail herein. One of the first direction and the second direction may be a clockwise direction, and the other may be a counterclockwise direction.
In this scheme, through the sliding fit of the mating protrusion 310 with the spiral guiding structure 421 and the guiding hole 411, the relative position between the lifting cylinder 300 and the main body 400 can be changed, so that the camera module is simple in structure and low in manufacturing cost.
In order to reduce friction force when the first cylinder 410 and the second cylinder 420 rotate, the second cylinder 420 is prevented from being jammed during rotation. In another alternative embodiment, the camera module disclosed in the embodiments of the present application may further include at least three balls 700, and the at least three balls 700 may be spaced apart along the circumference of the first cylinder 410. The at least three balls 700 are rollably with respect to the first cylinder 410 and the second cylinder 420. The first cylinder 410 supports the second cylinder 420 through at least three balls 700. In this case, the contact area between the balls 700 and the first and second cylinders 410 and 420 is small, so that the rotation between the first and second cylinders 410 and 420 is more flexible. Meanwhile, the balls 700 are in rolling fit with the first cylinder 410 and the second cylinder 420, and the friction coefficient of the rolling fit is smaller than that of the sliding fit, so that the second cylinder 420 rotates more easily relative to the first cylinder 410, and the phenomenon of jamming and the like is not easy to occur.
In addition, the number of the balls 700 is at least three, and the second cylinder 420 can be stably supported by the three balls 700, so that the stress of the second cylinder 420 is relatively balanced, and the second cylinder 420 is not easy to incline.
In the above embodiment, when the pre-compression force of the first cylinder 410 and the second cylinder 420 on the balls 700 is small, the balls 700 may be caused to fall from between the first cylinder 410 and the second cylinder 420, thereby affecting the rotation of the second cylinder 420. Based on this, in another alternative embodiment, at least one of the first cylinder 410 or the second cylinder 420 may be provided with at least three sliding grooves, and the sliding grooves may extend along the circumferential direction of the first cylinder 410, and at least three balls 700 are in one-to-one correspondence with at least three sliding grooves, and each ball 700 is in sliding fit with the corresponding sliding groove. In this embodiment, the sliding position of the ball 700 can be limited by the sliding groove, so that the ball 700 is prevented from falling, and the rotation of the second cylinder 420 is not easily affected.
In addition, the sliding groove can also limit the sliding distance of the ball 700, so as to assist in limiting the rotation angle of the second cylinder 420 and prevent the transition rotation of the second cylinder 420.
In the above embodiment, the transitional rotation of the second cylinder 420 easily applies a large force to the spiral guide structure 421 or the fitting projection 310, thereby causing damage to the spiral guide structure 421 or the fitting projection 310. In another alternative embodiment, the first cylinder 410 may be provided with a first limiting portion 412, and the second cylinder 420 may be provided with a second limiting portion 422, the first limiting portion 412 and the second limiting portion 422 being in a limiting engagement in the rotational direction of the first cylinder 410. In this scheme, the first limiting portion 412 and the second limiting portion 422 can limit the rotation angle of the second cylinder 420, so as to prevent the second cylinder 420 from transitional rotation, and further make the security and reliability of the camera module higher.
Alternatively, the rotation angle of the second cylinder 420 may be 30 °, 45 °, 60 °, or the like, and of course, the second cylinder 420 may be other rotation angles, which is not limited herein.
Further, the first limiting portion 412 may be a limiting recess, and the limiting recess may extend along the circumferential direction of the first cylinder 410. The second limiting portion 422 may be a limiting protrusion, and at least a portion of the limiting protrusion may be located in the limiting recess. In this solution, the limiting protrusion may extend into the limiting recess, so that the stacking height of the second cylinder 420 and the first cylinder 410 is lower, and thus the height of the camera module is further reduced.
In an alternative embodiment, the spiral guiding structure 421 may be a spiral groove, i.e. is concavely formed on the side wall of the second cylinder 420 in a non-penetrating manner, so that the strength of the whole second cylinder 420 can be ensured. Or the spiral guiding structure 421 may be a spiral hole, that is, disposed on the side wall of the second cylinder 420 in a penetrating manner, so that the assembly between the spiral guiding structure 421 and the fitting protrusion 310 can be facilitated under the condition that the strength of the second cylinder 420 is ensured to meet the use requirement. Meanwhile, it should be noted that, for the spiral guiding structure 421, no matter the spiral hole or the spiral groove is formed, the travel of the engaging protrusion 310 in the moving direction can be comprehensively determined by the length and the spiral angle of the spiral guiding structure itself, so as to control the extension and retraction of the second reflecting mirror 220 relative to the main body 400, and control the second reflecting mirror 220 more accurately.
In another alternative embodiment, the number of the fitting protrusions 310 may be plural, and the plural fitting protrusions 310 may be disposed at intervals along the circumferential direction of the elevation cylinder 300. The number of the spiral guide structures 421 may be plural, and the plurality of spiral guide structures 421 may be disposed at intervals. The number of the guide holes 411 may be plural, and the plural guide holes 411 may be arranged at intervals. Each of the coupling protrusions 310 may pass through the corresponding guide hole 411 and be coupled with the corresponding screw guide structure 421. In this scheme, the number and the position of the spiral guiding structure 421, the guiding hole 411 and the matching protrusion 310 are all corresponding, and each corresponding spiral guiding structure 421 is correspondingly matched with one matching protrusion 310 in a sliding manner, so that the driving mechanism 600 can more stably drive the lifting cylinder 300 in a multi-point matching manner, and the phenomenon that the lifting cylinder 300 tilts in the moving process is prevented.
In another alternative embodiment, the drive mechanism 600 may include a drive source 610 and a gear 620. The first cylinder 410 may be provided with a relief hole, and the second cylinder 420 may be provided with a plurality of engagement teeth 630 engageable with the driving source 610. A plurality of the engagement teeth 630 may be distributed along the circumferential direction of the second cylinder 420. The drive source 610 extends into the relief aperture to engage the plurality of engagement teeth 630. The drive source 610 may drive rotation of the second cylinder 420 via the gear 620 and the plurality of engagement teeth 630.
In this scheme, the driving mechanism 600 is in driving connection with the second cylinder 420 through a meshing transmission manner, and the meshing transmission has the advantage of higher transmission efficiency and transmission precision, so that the control precision of the second cylinder 420 is improved.
Further, the plurality of engagement teeth 630 may be integral with the second barrel 420. So be convenient for both carry out whole dismouting, improve the assemblability of module of making a video recording.
Alternatively, the driving source 610 may be a driving motor or an ultrasonic motor, and of course, the driving source 610 may be other driving structures, which are not limited herein.
In another alternative embodiment, the drive mechanism 600 may further include a worm 640, and the worm 640 may be coupled to the drive source 610. Worm 640 may be engaged with gear 620. The drive source 610 may drive the rotation of the gear 620 via the worm 640. In this scheme, the meshing transmission has the advantage of higher transmission efficiency and transmission precision, and the control precision of the second cylinder 420 is further improved.
In another alternative embodiment, the camera module disclosed herein may further include a transparent cover plate 100, where the transparent cover plate 100 may cover an end of the lifting cylinder 300 away from the photosensitive chip 500. The second reflector 220 may be disposed on the transparent cover 100, and the second reflector 220 is disposed in the middle of the transparent cover 100.
In a specific operation process, after the ambient light transmits through the transparent cover plate 100, the ambient light is reflected by the first reflecting mirror 210 to the second reflecting mirror 220, and then reflected by the second reflecting mirror 220 to the light-sensitive chip 500.
In this scheme, the light-transmitting cover plate 100 can play a protective role on other components in the camera module, so that the safety and reliability of the camera module are improved.
Alternatively, the transparent cover plate 100 may be made of transparent glass or transparent plastic, and of course, the transparent cover plate 100 may be made of other transparent materials, which is not limited herein.
In order to increase the optical path length of the camera module, in an alternative embodiment, the light-transmitting cover plate 100 is provided with a mounting hole 110, and the second reflecting mirror 220 may be mounted in the mounting hole 110. In this solution, when the positions of the light-transmitting cover plate 100 and the main body 400 are unchanged, the distance between the second reflecting mirror 220 and the first reflecting mirror 210 increases when the second reflecting mirror 220 is installed in the installation hole 110, so that the optical path length of the image capturing module increases, and the focal length of the image capturing module increases.
In an alternative embodiment, the end of the lifting cylinder 300 may be provided with an annular groove 320, and the light-transmitting cover plate 100 may be located in the annular groove 320. In this solution, the light-transmitting cover plate 100 is located in the annular groove 320, so that the overall height of the component formed by the lifting cylinder 300 and the light-transmitting cover plate 100 is smaller, and the height of the camera module is reduced.
