As shown in fig. 1 to 4, an embodiment of the present application discloses a camera module, which includes a module bracket 100, a camera 200, a first driving source 300, a telescopic arm 400, a telescopic member 500, and a swing arm 600.

The module holder 100 may serve as a base member of the camera module, which provides a mounting base for other components of the camera module. The first driving source 300 is provided to the module bracket 100, and alternatively, the first driving source 300 may be fixedly mounted on the upper surface of the module bracket 100, and the first driving source 300 may be a motor, a cylinder, or the like capable of outputting a driving force. The first end of the telescopic arm 400 is connected to the first driving source 300, and the second end of the telescopic arm 400 is connected to the extensible member 500, and optionally, the first driving source 300 is provided with a telescopic rod, the first end of the telescopic arm 400 may be fixedly connected to the telescopic rod, and the second end of the telescopic arm 400 may be fixedly connected to the extensible member 500. The telescopic arm 400 has the same movement pattern as the telescopic member 500, and the movement directions of the telescopic arm 400 and the telescopic member 500 may be parallel to each other, so that the telescopic arm 400 may more stably drive the telescopic member 500 to move. The extensible member 500 is connected to the module bracket 100, and the extensible member 500 may be directly connected to the module bracket 100 or indirectly connected to the module bracket 100, so that the extensible member 500 may move relative to the module bracket 100. The camera 200 is rotatably connected with the module bracket 100 through the swing arm 600, that is, the swing arm 600 can be directly or indirectly rotatably connected with the module bracket 100, so that the swing arm 600 can drive the camera 200 to rotate relative to the module bracket 100. The one end of swing arm 600 links to each other with extensible member 500, and consequently, when extensible member 500 removed, can drive the swing arm 600 swing, and swing arm 600 can drive camera 200 and rotate. That is, the first driving source 300 may drive the telescopic member 500 to move through the telescopic arm 400, and the telescopic member 500 drives the camera 200 to rotate through the swing arm 600.

In this embodiment, when the camera 200 shakes, the first driving source 300 can drive the telescopic part 500 to move through the telescopic arm 400, and the telescopic part 500 drives the camera 200 to rotate through the swing arm 600, so as to compensate the shake of the camera 200, and further achieve the anti-shake purpose. Because this application embodiment realizes the anti-shake through the mode that drives camera 200 and rotate, consequently need not reduce the picture quality to can improve the shooting effect of camera module.

In a further embodiment, the camera module further includes a second driving source 700 and a rotating shaft 800. The second driving source 700 is provided to the module bracket 100, and alternatively, the second driving source 700 may be fixedly installed on the upper surface of the module bracket 100 or in the module bracket 100, and the second driving source 700 may be a motor, a cylinder, or the like capable of outputting a driving force. The rotation shaft 800 is rotatably connected to the module holder 100, one end of the rotation shaft 800 is connected to the second driving source 700, the other end of the rotation shaft 800 is rotatably connected to the swing arm 600, and when the rotation shaft 800 rotates around its own axis, the swing arm 600 rotates around the axis of the rotation shaft 800. Alternatively, the swing arm 600 and the rotating shaft 800 are at least partially disposed in the telescopic member 500, and one end of the rotating shaft 800 connected to the swing arm 600 may pass through the module bracket 100 and be connected to the swing arm 600. With such a structure, the first driving source 300 can drive the swing arm 600 to rotate around a first axis relative to the rotating shaft 800, and the second driving source 700 can drive the swing arm 600 to rotate around a second axis through the rotating shaft 800, wherein the second axis intersects with or is different from the first axis. Alternatively, the first and second axes may be perpendicular to each other. When the camera 200 shakes in different directions, the first driving source 300 and the second driving source 700 can drive the camera 200 to rotate in different directions, so that the anti-shake effect can be achieved in more directions, and therefore, the anti-shake effect of the camera module can be further improved.

The swing arm 600 may be a straight rod structure, and both ends of the swing arm are respectively connected to the extendable element 500 and the camera 200, but the distance between the camera 200 and the extendable element 500 is short due to the structure, and the camera 200 is likely to interfere with the extendable element 500 when rotating. Based on this, in an alternative embodiment, the swing arm 600 may include a connecting shaft 610, a connecting arm 620, and a bending connection portion 630, wherein one end of the connecting arm 620 is connected to one end of the connecting shaft 610, the other end of the connecting arm 620 is connected to the extensible member 500, one end of the bending connection portion 630 is connected to the other end of the connecting shaft 610, and the other end of the bending connection portion 630 is connected to the camera 200 and is opposite to the rotation shaft 800. Since the bent connection portion 630 has a certain height in the axial direction of the rotation shaft 800, the distance between the camera 200 and the extensible member 500 is greater, so that the camera 200 is not easily interfered with the extensible member 500 when rotated. In addition, the connecting shaft 610, the connecting arm 620 and the bending connecting portion 630 further constitute a bending structure, which makes the layout of the camera 200 more flexible, thereby more reliably preventing the camera 200 from interfering with the extensible member 500 when rotating.

In order to simplify the structure of the bending connection portion 630, in an alternative embodiment, the bending connection portion 630 includes a first plate segment 631, a second plate segment 632, and a connection post 633, the first plate segment 631 is connected to the connection shaft 610, the second plate segment 632 is connected to the first plate segment 631, the second plate segment 632 is parallel to an axis of the connection shaft 610, one end of the connection post 633 is connected to the second plate segment 632, and the other end of the connection post 633 is connected to the camera 200, that is, the connection shaft 610 is connected to the camera 200 sequentially through the first plate segment 631, the second plate segment 632, and the connection post 633, and the first plate segment 631 and the second plate segment 632 form an L-shaped structure, so as to facilitate the camera 200 to approach to the center of the telescopic member 500, and further improve the stability of the entire camera module. Further, the axis of the connecting column 633 is collinear with the axis of the rotating shaft 800, and at this time, the rotating shaft 800 is located right below the connecting column 633, namely, right below the camera 200, so that the camera 200 is more reliably supported, and the camera 200 is prevented from being deformed due to the cantilever arrangement relative to the rotating shaft 800.

In an alternative embodiment, the module holder 100 includes a cylindrical portion 110, the cylindrical portion 110 is slidably engaged with the telescopic member 500, an outer surface of the cylindrical portion 110 is in a limit-fit engagement with an inner surface of the telescopic member 500 to limit the rotation of the telescopic member 500, and one end of the rotating shaft 800 passes through the cylindrical portion 110 and is connected to the swing arm 600. The cylindrical part 110 may provide a guide for the movement of the telescopic member 500 so that the telescopic member 500 is more smoothly telescopic with respect to the module bracket 100; meanwhile, the rotation of the extensible member 500 with respect to the module bracket 100 is restricted by the cylindrical part 110, so that the extensible member 500 is not easily rotated by an external force, and thus abrasion between components can be alleviated, thereby extending the service life of the camera module.

Further alternatively, the module holder 100 may further include a holder body to which the cylindrical part 110 is connected, and the first driving source 300 and the second driving source 700 may be mounted. In addition, the cylindrical part 110 may have a prism structure, such as a quadrangular prism structure, and the outer surface thereof may have a prism surface, such as a quadrangular prism surface, and correspondingly, the inner surface of the extensible member 500 may also have a prism surface, such as a quadrangular prism surface, and the two prism surfaces are in contact with each other, thereby restricting the rotation of the extensible member 500. Of course, the outer surface of the cylindrical portion 110 and the inner surface of the telescopic member 500 may also adopt other structural forms, which is not limited in the embodiment of the present application.

The telescopic member 500 may be a cylindrical structure with a constant cross-sectional area, and in other embodiments, the cross-sectional area of the end of the telescopic member 500 close to the camera 200 is larger than the cross-sectional area of the end of the telescopic member 500 far from the camera 200. It should be noted that the cross section is perpendicular to the axis of the rotating shaft 800, and the cross sectional area refers to the area of the portion surrounded by the outer peripheral surface of the telescopic member 500. So configured, the size of the end of the telescopic member 500 near the camera 200 is larger, and the telescopic member 500 can transmit the acting force to the camera 200 through the end, so the acting force can be transmitted more reliably by this configuration.

In an alternative embodiment, the inner surface of the telescopic member 500 is provided with an annular sliding groove 510, the annular sliding groove 510 surrounds the rotating shaft 800, and one end of the swing arm 600 is slidably engaged with the annular sliding groove 510. This annular chute 510 is the enclosed construction, compares in the spout that does not seal, and this annular chute 510 makes camera 200 can carry out 360 rotations for extensible member 500, consequently when realizing the anti-shake, the rotation amplitude and the pivoted initial point and the terminal point of camera 200 are unrestricted to be favorable to the camera module to realize wider anti-shake, conveniently select the best rotation path simultaneously, thereby shorten the required time of anti-shake, further improve the anti-shake effect. In addition, the top wall and the bottom wall of the annular sliding groove 510 can be in limit fit with the swing arm 600, so that the swing arm 600 is driven to swing more stably when the telescopic member 500 moves.

The axis of the rotating shaft 800 may be collinear with the center line of the annular sliding groove 510, but this structure may result in a smaller distance between the rotating shaft 800 and the annular sliding groove 510, and the length of the swing arm 600 may be affected by the position of the rotating shaft 800, so the structure may result in a shorter swing arm 600, and the first driving source 300 may need to output a larger driving force to drive the swing arm 600 to swing. In view of this, the rotating shaft 800 may be eccentrically disposed with respect to the center of the annular sliding groove 510, so as to reserve more installation space for the swing arm 600, and thus the length of the swing arm 600 may be appropriately increased, so that the first driving source 300 may drive the swing arm 600 to swing by a smaller driving force, thereby achieving the effect of saving labor. Meanwhile, in the case where the first driving source 300 outputs the same driving force, the camera 200 that the swing arm 600 can drive may be larger.

In the foregoing, the first driving source 300 is provided with a telescopic rod, the first end of the telescopic arm 400 can be fixedly connected with the telescopic rod, and when the telescopic rod is adopted to drive the telescopic arm 400 to move, the telescopic rod and the telescopic arm 400 both need a large movement space, so that the whole occupied space of the camera module is large. In order to solve this problem, alternatively, the telescopic arm 400 includes a rack portion 410, a coupling portion 420, and an annular fitting portion 430, the first driving source 300 is provided with a driving gear 310, the rack portion 410 extends in a moving direction of the telescopic member 500, and the rack portion 410 is engaged with the driving gear 310, the annular fitting portion 430 is coupled with the rack portion 410 through the coupling portion 420, and the annular fitting portion 430 surrounds the telescopic member 500, and the first driving source 300 drives the telescopic member 500 to move through the annular fitting portion 430. In this embodiment, the first driving source 300 can output a rotational driving force through the driving gear 310, the driving gear 310 can move the entire telescopic arm 400 through the rack portion 410, and the ring-shaped engagement portion 430 of the telescopic arm 400 further rotates the swing arm 600. Therefore, the driving gear 310 only needs to rotate, and therefore the camera module occupies a smaller space. In addition, the contact area of the annular matching part 430 and the telescopic part 500 is large, so that the telescopic part 500 can be driven to move more stably, the contact positions of the annular matching part 430 and the telescopic part 500 are distributed more uniformly, and the problem of jamming is not easy to occur when the telescopic part 500 moves.

Optionally, the end of the swing arm 600 is provided with a spherical protrusion 601, and the spherical protrusion 601 is hinged with the telescopic member 500. Since the outer surface of the spherical protrusion 601 is smooth, the spherical protrusion 601 always keeps a large contact area with the telescopic member 500 during the rotation of the swing arm 600 relative to the telescopic member 500, thereby alleviating the wear caused by the relative movement of the two.
