The following describes in detail a camera module and an electronic device provided in the embodiments of the present application through specific embodiments and application scenarios thereof with reference to the accompanying drawings.
As shown in fig. 1 to 13, an embodiment of the present application discloses a camera module, which includes a base 100, a camera 200, and a driving assembly 300.
The base 100 can be as the basic component of camera module, and it can provide the installation basis for other parts of camera module, and this base 100 can set to hexahedron hollow structure, and its top can set up to the open end to in installation camera 200, base 100 can wrap up camera 200's at least part this moment, thereby protection camera 200.
The camera 200 is one of the core functional devices of the camera module, the camera 200 is rotatably connected to the base 100, the camera 200 has a light incident end 210 and a first surface 220 departing from the light incident end 210, the first surface 220 can be opposite to the bottom surface of the base 100 facing the opening end thereof, that is, the first surface 220 and the bottom surface of the base 100 can be arranged along the direction of the optical axis of the camera 200. Alternatively, the first face 220 of the camera 200 may be a plane; the camera 200 may be a general camera or a micro-cloud camera.
The driving assembly 300 may apply a force to the camera 200 to drive the camera 200 to rotate relative to the base 100, the driving assembly 300 is disposed on the base 100, and the driving assembly 300 includes a driving source, a state switching member 310, a transmission member 320, a first driving member 330, and a second driving member 340. The driving source may be a servo motor or other components capable of outputting driving force, the state switching element 310 may move relative to the base 100, that is, the state switching element 310 may perform state switching through its own movement, and during the movement of the state switching element 310, the state switching element 310 may apply an acting force to the first driving element 330 and the second driving element 340, so that the positional relationship between the first driving element 330 and the second driving element 340 and the transmission element 320 is changed, and finally the transmission path between the transmission element 320 and the camera 200 is changed. Alternatively, the state switch 310 may perform state switching in a moving manner. In addition, a motor may be additionally provided to drive the state switching member 310 to move.
When the first driving member 330 is connected to the transmission member 320, the first driving member 330 abuts against the first surface 220, and the driving source drives the camera 200 to rotate around the first axis relative to the base 100 through the transmission member 320 and the first driving member 330, so as to realize anti-shake in the first direction; under the condition that the second driving member 340 is connected with the transmission member 320, the second driving member 340 abuts against the first surface 220, the driving source drives the camera 200 to rotate around a second axis relative to the base 100 through the transmission member 320 and the second driving member 340, and the second axis intersects with or is different from the first axis, so that the anti-shake function in the second direction is realized. Optionally, the bottom surface of the base 100 may be provided with an avoiding hole corresponding to the first driving member 330 and the second driving member 340, so that the first driving member 330 and the second driving member 340 can be connected to the camera 200. It should be noted that, in the case that the first driving element 330 is connected to the transmission element 320, the second driving element 340 and the transmission element 320 may be separated, that is, no power transmission is performed therebetween; in the case where the second driving member 340 is connected to the driving member 320, the first driving member 330 and the driving member 320 may be separated, i.e., no power transmission therebetween.
Since the driving source, the state switching member 310, the transmission member 320, the first driving member 330 and the second driving member 340 are all non-electromagnetic structures, the problem of electromagnetic interference is not easily caused when the camera module works. Meanwhile, the camera 200 can be prevented from shaking in the first direction and the second direction through the structure, so that a better anti-shaking effect is achieved, and the problems that image edge smear is obvious during long-time exposure and the like are solved.
Alternatively, the first direction may be an X direction in fig. 1, the second direction may be a Y direction in fig. 1, the first axis and the second axis may intersect, and further, the first axis may be perpendicular to the second axis. In addition, the first axis and the second axis can intersect with the optical axis of the camera 200, so that the rotation range of the camera 200 is larger, and a better anti-shake effect is realized.
In the process of the movement of the state switching member 310, the first driving member 330 and the second driving member 340 can move sequentially, for example, the state switching member 310 drives the first driving member 330 to move first, so as to change the position of the first driving member 330, and then drives the second driving member 340 to move, so as to change the position of the second driving member 340. Alternatively, when the state switching member 310 moves, the first driving member 330 and the second driving member 340 move simultaneously, alternatively, the first driving member 330 and the second driving member 340 may be disposed at intervals along the circumferential direction of the transmission member 320, and both the first driving member 330 and the second driving member 340 are movably disposed on the base 100. Under the condition that the state switching member 310 drives the first driving member 330 to move away from the transmission member 320, the second driving member 340 moves close to the transmission member 320 and moves close to the first surface 220; when the state switching member 310 drives the second driving member 340 to move away from the transmission member 320, the first driving member 330 approaches the transmission member 320 and approaches the first surface 220. In this embodiment, once the state switching member 310 moves, the first driving member 330 and the second driving member 340 move simultaneously, so as to change the connection relationship between the first driving member 330 and the second driving member 340, the transmission member 320 and the camera 200. Therefore, the structure can shorten the state switching time of the camera module, thereby realizing rapid anti-shake.
It is mentioned above that the state switching member 310 can realize the state switching in a moving manner, and in other embodiments, the state switching member 310 can also realize the state switching in a rotating manner. In contrast, when the rotation mode is adopted, the movement space required by the state switching member 310 is smaller, and therefore, the driving assembly 300 can be more compact and occupy less space. In order to realize the state switching of the state switching member 310 by rotating, the outer peripheral surface of the state switching member 310 may be respectively abutted against the first driving member 330 and the second driving member 340, the state switching member 310 is rotatably connected to the base 100, and when the state switching member 310 rotates, the outer peripheral surface of the state switching member 310 drives the first driving member 330 and the second driving member 340 to approach or separate from the transmission member 320. Alternatively, when the outer circumferential surface of the state switching member 310 drives the first driving member 330 away from the transmission member 320, the second driving member 340 may approach the transmission member 320; when the outer peripheral surface of the state switching member 310 drives the second driving member 340 to move away from the transmission member 320, the first driving member 330 may approach the transmission member 320. In other words, the state switching element 310 can apply a force to the first driving element 330 and the second driving element 340 through its outer periphery, so as to drive the first driving element 330 and the second driving element 340 to move, thereby changing the relative positions of the first driving element 330 and the transmission element 320 and the relative positions of the second driving element 340 and the transmission element 320.
The state switching member 310 is disposed between the first surface 220 and the transmission member 320, so that the state switching member 310 is disposed by fully utilizing the space between the first surface 220 and the transmission member 320, and the structure of the camera module is more compact. The state switching member 310 can rotate eccentrically to drive the first driving member 330 and the second driving member 340 to move, in other alternative embodiments, the outer peripheral surface of the state switching member 310 includes a first engaging surface 311 and a second engaging surface 312 connected to each other, and the distance between the first engaging surface 311 and the rotation center of the state switching member 310 is smaller than the distance between the second engaging surface 312 and the rotation center of the state switching member 310. Alternatively, the first engagement surface 311 and the second engagement surface 312 may be regular surfaces or irregular surfaces, and a distance between any one of the first engagement surfaces 311 and the rotation center of the state switching member 310 is smaller than a distance between any one of the second engagement surfaces 312 and the rotation center of the state switching member 310.
Under the condition that the first mating surface 311 is abutted with the first driving member 330, the second mating surface 312 is abutted with the second driving member 340, so that the first driving member 330 is closer to the transmission member 320 and is connected with the transmission member 320, and the second driving member 340 is farther from the transmission member 320 and is not connected with the transmission member 320. Under the condition that the first mating surface 311 is abutted with the second driving member 340, the second mating surface 312 is abutted with the first driving member 330, so that the second driving member 340 is closer to the transmission member 320 and is connected with the transmission member 320, and the first driving member 330 is farther from the transmission member 320 and is not connected with the transmission member 320. In this embodiment, the first driving member 330 and the second driving member 340 are driven to move by arranging the outer peripheral surface of the state switching member 310, so that the state switching member 310 does not need to rotate eccentrically, and the moving space required by the state switching member 310 is smaller.
Alternatively, the first engagement surface 311 may be provided as a plane, and the first engagement surface 311 may be parallel to the rotation axis of the state switching member 310, thereby facilitating the processing of the first engagement surface 311. The second engagement surface 312 may be an arc surface, both ends of the arc surface may be connected to the first engagement surface 311, and the curvature of the connection portion may gradually change, so that the outer circumferential surface of the state switching member 310 is smoothly transited, and the movement of the first driving member 330 and the second driving member 340 is more stable.
In a further alternative embodiment, the driving assembly 300 further includes a path switching member 350, and a driving source is connected to the path switching member 350, and the driving source can drive the path switching member 350 to switch between the first position and the second position. When the path switching member 350 is located at the first position, the path switching member 350 is connected to the state switching member 310, and the driving source drives the state switching member 310 to rotate through the path switching member 350; in the case where the path switching member 350 is located at the second position, the path switching member 350 is connected to the transmission member 320, and the driving source drives the transmission member 320 to move through the path switching member 350. In other words, the state switching member 310 and the transmission member 320 can be driven to move by the same driving source, and compared to a scheme in which the motor is separately provided to drive the state switching member 310 to move, this embodiment can reduce the components included in the driving assembly 300, thereby allowing the driving assembly 300 to occupy a smaller space.
Alternatively, the path switching part 350 may be connected to the state switching part 310 through a connection column, so as to drive the state switching part 310 to move; similarly, the path switching member 350 may be connected to the transmission member 320 through a connection column, so as to drive the transmission member 320 to move. However, such a connection manner is easily failed due to the breakage of the connection column, and to solve this problem, the state switching member 310 may be provided with a first ring gear 313, the transmission member 320 is provided with a second ring gear 321, a diameter of the first ring gear 313 is smaller than a diameter of the second ring gear 321, the path switching member 350 includes a first gear 351 and a second gear 352 connected to each other, the second gear 352 is located between the first gear 351 and the drive source, and a diameter of the first gear 351 is smaller than a diameter of the second gear 352. With the path switching member 350 in the first position, the first gear plate 351 is engaged with the first ring gear 313, and the second gear plate 352 is separated from the second ring gear 321; with the path switching member 350 in the second position, the first gear plate 351 is separated from the first ring gear 313, and the second gear plate 352 is engaged with the second ring gear 321. In this embodiment, the first ring gear 313 and the first gear plate 351 and the second ring gear 321 and the second gear plate 352 form a larger contact area, so that the connection between the path switching member 350 and the state switching member 310 and the connection between the path switching member 350 and the transmission member 320 are not easily lost.
The path switching member 350 may be movable between a first position and a second position, and thus the driving source may be configured to simultaneously satisfy the requirements of moving the path switching member 350 and rotating the driving state switching member 310 and the transmission member 320.
Further, the first surface 220 of the camera 200 is provided with a first matching groove 221, the driving assembly 300 further includes a third driving member 360, the third driving member 360 is disposed on the state switching member 310, the base 100 is provided with a blocking portion 110, the blocking portion 110 faces the first surface 220, the blocking portion 110 is provided with a through hole 111, and the through hole 111 can be a strip-shaped arc-shaped hole. Under the condition that third driver 360 and the one side butt that separation portion 110 deviates from camera 200, third driver 360 and first face 220 separation, separation portion 110 separates third driver 360 and camera 200 promptly, and third driver 360 can't exert the effort to camera 200. In a case that one end of the third driving member 360 passes through the through hole 111, the one end of the third driving member 360 is engaged with the first engaging groove 221 to drive the camera 200 to rotate around a third axis relative to the base 100, wherein the first axis and the second axis are both intersected with or out of plane with the third axis, and optionally, the third axis is substantially parallel to the optical axis of the camera 200, so as to achieve the anti-shake of the camera 200 in the Z direction shown in fig. 1. Firstly, the embodiment can realize anti-shake in more directions, thereby improving the anti-shake effect; secondly, when the driving assembly 300 drives the camera 200 to rotate around the first axis or around the second axis, the blocking portion 110 separates the third driving member 360 from the camera 200, so that the movement of the camera 200 in each direction is relatively independent, and the anti-shake function is realized more accurately.
Alternatively, the third driving member 360 may be integrally formed as an elastic member, so that it can be compressed by the blocking portion 110, and also can recover its deformation to connect with the camera 200 through the through hole 111, but such a configuration would result in a limitation of the material for manufacturing the third driving member 360, and thus, an excessive frictional force between the third driving member 360 and the blocking portion 110 is likely to occur. Thus, in another alternative embodiment, the third driving member 360 includes a telescopic member 361 and a first elastic member 362, the telescopic member 361 is movably disposed on the state switching member 310, one end of the first elastic member 362 is connected to the telescopic member 361, and the other end of the first elastic member 362 is connected to the state switching member 310. Because extensible member 361 and first elastic component 362 set up separately, the deformation demand of third driving piece 360 need not be compromise to the manufacturing material of extensible member 361, just can select more nimble to minimize the frictional force between third driving piece 360 and separation portion 110, with this drive power that reduces the driving source and need export, reach the mesh that reduces the consumption of camera module.
Further alternatively, a first groove may be disposed on a surface of the state switching member 310 facing the camera 200, and the third elastic member 343 and the telescopic member 361 are at least partially disposed in the first groove, where the first groove may limit the lateral displacement of the third elastic member 343 and the telescopic member 361, so as to enable the third driving member 360 to move more reliably. In addition, a second groove can be formed on the surface of the telescopic member 361 facing away from the camera 200, and the third elastic member 343 is at least partially located in the second groove, so that the telescopic member 361 can be more reliably connected with the third elastic member 343; one end of the extensible member 361 facing the camera 200 may be configured as a tapered end, so that the extensible member 361 may gradually enter the through hole 111 and gradually separate from the through hole 111, thereby improving the smoothness of the extensible member 361 during movement.
The position of the third driving member 360 on the state switching member 310 can be flexibly selected, for example, the third driving member 360 can be disposed at a position closer to the center line of the state switching member 310, but considering that the position has more parts, which is not beneficial to disposing the third driving member 360, the third driving member 360 can be disposed at the edge of the state switching member 310, so as to facilitate disposing the third driving member 360. In addition, when the optical axis of the camera 200 is closer to or even intersects or coincides with the rotation axis of the state switching member 310, the third driving member 360 is disposed at the edge of the state switching member 310, so that the third driving member 360 is farther from the rotation center of the camera 200, thereby increasing the force arm of the driving force acting on the camera 200, and the driving source drives the camera 200 to rotate more laborsavingly.
In an alternative embodiment, the transmission member 320 may be a transmission gear, an axis of the transmission member 320 is perpendicular to the first surface 220 of the camera head 200, the first driving member 330 includes a first driving wheel 331, the second driving member 340 includes a second driving wheel 341, and an axis of the first driving wheel 331 and an axis of the second driving wheel 341 are both parallel to the first surface 220 of the camera head 200. The first driving wheel 331 and the second driving wheel 341 can be respectively engaged with the transmission member 320, and when the first driving wheel 331 is engaged with the transmission member 320, the camera 200 rotates around the first axis relative to the base 100; when the second driving wheel 341 engages with the transmission member 320, the camera 200 rotates around the second axis relative to the base 100. In this embodiment, the transmission gear may be provided with only a partial transmission gear as shown in fig. 3, or may be provided with a complete transmission gear as shown in fig. 11; the first and second drivers 330, 340 may each be bevel gears. Compare in the axis of driving medium 320 not with the perpendicular scheme of the first face 220 of camera 200, the axis of driving medium 320 can make driving medium 320 be closer to camera 200 with first face 220 is perpendicular, and the structure of camera module is compacter, and simultaneously, driving medium 320 and first drive wheel 331 and driving medium 320 and second drive wheel 341 all can form great area of contact to promote transmission reliability.
In order to realize the connection between the first driving member 330 and the camera 200, the first driving wheel 331 can be set to be a deformable structure after being electrified, so that the first driving member 330 can abut against the camera 200 and can be separated from the camera 200, but the structure can further increase the power consumption and the control difficulty of the camera module. In view of this, in another alternative embodiment, the first driving member 330 further includes a first driving pin 332, the first driving pin 332 is movably disposed on the first driving wheel 331, the base 100 is further provided with a first receiving groove 120, and the first side 220 of the camera 200 is provided with a second engaging groove 222. In the case that the first driving member 330 is connected to the driving member 320, the first driving pin 332 is located outside the first receiving groove 120, and a first end of the first driving pin 332 is engaged with the second engaging groove 222; in the case where the second driving member 340 is connected to the transmission member 320, the second end of the first driving pin 332 is engaged with the first receiving groove 120, and the first driving pin 332 is located outside the second engaging groove 222. In the process that the first driving wheel 331 moves in the direction of its own axis, the first driving pin 332 may be switched between a state of being engaged with the first receiving groove 120 and a state of being disengaged from the first receiving groove 120, thereby changing the engagement state of the first driving pin 332 with the second engagement groove 222. In this embodiment, the position of the first driving pin 332 can be changed synchronously in the moving process of the first driving wheel 331, so that the connection state between the first driving member 330 and the camera 200 does not need to be changed by consuming power, thereby reducing the power consumption and the control difficulty of the camera module.
Similarly, in order to realize the connection between the second driving member 340 and the camera 200, the second driving wheel 341 may be configured to be deformable after being electrified, so that the second driving member 340 may abut against the camera 200 or may be separated from the camera 200. In another embodiment, the second driving member 340 further includes a second driving pin 342, the second driving pin 342 is movably disposed on the second driving wheel 341, the base 100 is further provided with a second receiving slot, and the first surface 220 is further provided with a third engaging slot. Under the condition that the first driving piece 330 is connected with the transmission piece 320, the third end of the second driving pin 342 is matched with the second accommodating groove, and the second driving pin 342 is positioned outside the third matching groove; in the case where the second driving member 340 is connected to the driving member 320, the fourth end of the second driving pin 342 is engaged with the third engaging groove, and the second driving pin 342 is located outside the second receiving groove. In the process that the second driving wheel 341 moves in the direction of the axis thereof, the second driving pin 342 may be switched between a state of being engaged with and disengaged from the second receiving groove, thereby changing the engagement state of the second driving pin 342 with the third engaging groove. In this embodiment, the position of the second driving pin 342 can be changed synchronously during the movement of the second driving wheel 341, so that the connection state between the second driving member 340 and the camera 200 does not need to be changed by power consumption, thereby reducing the power consumption and the control difficulty of the camera module.
Further, the base 100 is further provided with a first positioning column 130, the first positioning column 130 extends along the axial direction of the first driving wheel 331, the first driving wheel 331 is sleeved on the first positioning column 130, and the first positioning column 130 is provided with a first accommodating groove 120. The first positioning post 130 can be configured to receive the first drive wheel 331 on one hand and provide guidance for movement of the first drive wheel 331 to allow the first drive wheel 331 to move more smoothly on the other hand. Moreover, the first positioning post 130 is provided with the first receiving groove 120, so that no additional component is required to be added to provide the first receiving groove 120, and the structure of the first driving member 330 is simpler and more compact. Further, the first driving pin 332 may extend perpendicular to the first face 220 of the camera head 200, so that the first driving pin 332 more effectively drives the camera head 200 to rotate.
Similarly, the base 100 further has a second positioning column extending along the axis of the second driving wheel 341, the second driving wheel 341 is sleeved on the second positioning column, and the second positioning column has a second receiving groove. The second positioning posts herein can mount the second driving wheel 341 on the one hand and provide guidance for the movement of the second driving wheel 341 on the other hand, so that the second driving wheel 341 can move more smoothly. Moreover, the second accommodating groove is formed in the second positioning column, so that additional parts are not needed to be added to form the second accommodating groove, and the structure of the second driving part 340 is simpler and more compact. Further, the second driving pin 342 extends perpendicularly to the first face 220 of the camera head 200, so that the second driving pin 342 more effectively drives the camera head 200 to rotate.
When the transmission member 320 no longer applies a force to the first driving wheel 331 (or the second driving wheel 341), the first driving wheel 331 (or the second driving wheel 341) needs to be close to the transmission member 320 so as to be connected to the transmission member 320, and for this reason, the base 100 may be configured as an elastic member so that the base 100 can apply a restoring force to the first driving wheel 331 (or the second driving wheel 341), but such configuration may result in insufficient rigidity of the base 100 and poor supporting effect on other components. Therefore, optionally, the first driving member 330 further comprises a second elastic member 333, one end of the second elastic member 333 is connected to the base 100, and the other end of the second elastic member 333 is connected to the first driving wheel 331; the second driving member 340 may further include a third elastic member 343, one end of the third elastic member 343 is connected to the base 100, and the other end of the third elastic member 343 is connected to the second driving wheel 341. This embodiment achieves the restoration of the first driving wheel 331 by the second elastic member 333, and achieves the restoration of the second driving wheel 341 by the third elastic member 343, so the base 100 can be configured to have a more rigid structure to improve the supporting effect thereof on other components.
In an alternative embodiment, a part of the camera 200 may directly contact with the base 100, as long as the camera 200 can rotate relative to the base 100, but in order to ensure that the camera 200 rotates relative to the base 100 more smoothly, the solution may impose a higher requirement on the structure of the camera 200, and is therefore not favorable for the structural design of the camera module. In other embodiments, the camera module further includes a ball joint 400, the ball joint 400 is disposed between the base 100 and the camera 200, and the camera 200 is rotatably connected to the base 100 through the ball joint 400. At this time, the camera 200 can rotate in any direction relative to the base 100, so the structure of the camera 200 basically does not need to be adjusted, and therefore the embodiment is more beneficial to the structural design of the camera module.
Optionally, the camera module may further include a fourth elastic member 500, the base 100 further has an inner side surface, and the camera 200 further has an outer peripheral surface, and the fourth elastic member 500 is connected between the inner side surface and the outer peripheral surface. When camera 200 rotates for base 100, the distance between the medial surface of base 100 and the outer peripheral face of camera 200 will change, and fourth elastic component 500 can exert the effort to base 100 and camera 200 simultaneously, prevents both collisions, still can provide the damping effect for camera 200's rotation simultaneously for camera 200 rotates more steadily.
The number of the fourth elastic members 500 may be one or more, and when the number of the fourth elastic members 500 is more, the plurality of fourth elastic members 500 may achieve a buffering effect at more positions, so that the camera 200 rotates in multiple directions relative to the base 100 more stably. In addition, in an alternative embodiment, the first elastic member 362, the second elastic member 333, the third elastic member 343, and the fourth elastic member 500 may be springs.
