The camera structure that this application embodiment provided includes: the device comprises a universal shaft 2, an outer holder 9, an inner holder 5 accommodated in the outer holder 9, a holder carrier 10, a first driving mechanism (not numbered), a second driving mechanism (not numbered), a camera assembly 20 and a first flexible circuit board 23.

The first flexible circuit board 23 forms a bent elastic structure, the camera assembly 20 is elastically connected with the cradle head outer support 9 through the first flexible circuit board 3, so that the camera assembly 20 can move relative to the cradle head outer support 9, and the camera assembly 20 is fixedly connected with the cradle head carrier 10; two supporting parts 25 axially distributed along a first axis of the cardan shaft 2 are respectively hinged with the outer holder 9 of the holder, and two supporting parts 25 axially distributed along a second axis of the cardan shaft 2 are respectively hinged with the inner holder 5 of the holder, wherein the first axis is intersected with the second axis; the first driving mechanism is respectively connected with the outer holder 9 and the inner holder 5 to drive the inner holder 5 to rotate along the first axis and/or rotate along the second axis relative to the outer holder 9.

In addition, the holder carrier 10 is connected with the bottom of the holder inner bracket 5 in a sliding way; the second driving mechanism is respectively connected with the holder inner support 5 and the holder carrier 10 to drive the holder carrier 10 to rotate along a third axis relative to the holder inner support 5, wherein the third axis is respectively perpendicular to the first axis and the second axis.

In a specific implementation, the first axis may extend in the same direction as the line H shown in fig. 1, the second axis may extend in the same direction as the line M shown in fig. 1, and the third axis may be the axis Z shown in fig. 1. In this embodiment, the 4 supporting portions 25 of the universal shaft 2 may be respectively located at 4 top corners of a square, in which case, the first shaft and the second shaft are perpendicular, but in practical applications, the structure of the universal shaft 2 may be diversified, and the first shaft and the second shaft may not be perpendicular to each other, for example: the included angle between the first shaft and the second shaft is larger than 0 degrees and smaller than 180 degrees.

In practice, the rotation of the driving inner cradle head support 5 with respect to the outer cradle head support 9 along the first axis and/or along the second axis can be understood as: the inner cradle head support 5 is driven to rotate along an X axis or rotate along a Y axis relative to the outer cradle head support 9, wherein the outer cradle head support 9 can be in a rectangular structure, and the X axis and the Y axis are respectively parallel to two mutually perpendicular rectangular edges on the outer cradle head support 9.

Specifically, during the rotation of the inner cradle head support 5 relative to the outer cradle head support 9 along the first axis, it has rotation components in the directions of the X axis and the Y axis; similarly, during the rotation of the inner pan-tilt support 5 with respect to the outer pan-tilt support 9 along said second axis, it also has a component of rotation along the X-axis and Y-axis directions. At this time, if it is only necessary to drive the inner holder 5 to rotate along the X axis relative to the outer holder 9, the component along the Y axis direction in the process of rotating the inner holder 5 relative to the outer holder 9 along the second axis and the component along the Y axis direction in the process of rotating the inner holder 5 relative to the outer holder 9 along the second axis may be offset with each other, so as to drive the inner holder 5 to rotate along the X axis relative to the outer holder 9.

The camera assembly 20 is fixedly connected with the pan/tilt head carrier 10, and it can be understood that: the outer wall of the camera component 20 is attached and fixedly connected with the inner wall of the holder carrier 10.

In practical applications, as shown in fig. 1 and fig. 2, the camera structure provided in the embodiment of the present application may include: the housing 1, the housing 1 may include a top case 1a and a bottom case 1 b. The bottom shell 1b is recessed in a direction away from the top shell 1a to form an accommodating space between the top shell 1a and the bottom shell 1b, and the universal shaft 2, the outer cradle head support 9, and the inner cradle head support 5, the cradle head carrier 10, the first driving mechanism, the second driving mechanism, the camera assembly 20, and the first flexible circuit board 23 accommodated in the outer cradle head support 9 can be accommodated in the accommodating space of the housing 1. In addition, the top case 1a, the universal shaft 2, the outer holder 9, the inner holder 5 and the holder carrier 10 are all provided with a light-passing hole, so that the camera assembly 20 below the top case collects image information through the light-passing hole, and even the head of the camera assembly 20 (i.e. above the Z axis in fig. 1) is exposed out of the top case 1a through the light-passing hole.

In this way, the camera structure provided by the embodiment of the present application can be enclosed into an integral structure through the housing 1, and the first flexible circuit board 23 and other structures inside the housing 1 can also be protected.

In a specific embodiment, the first driving mechanism and the second driving mechanism may be a motor driving mechanism, an electromagnetic driving mechanism, and the like, and for convenience of description, only the first driving mechanism and the second driving mechanism are described as an example of the electromagnetic driving mechanism in the following embodiments, and are not limited to this.

In addition, in the coordinate axes shown in fig. 2, Rx, Ry, and Rz indicate directions of rotation along the X, Y, and Z axes, respectively.

In the embodiment of the application, it is rotatory along Rz axle direction to follow the independent drive cloud platform carrier of second actuating mechanism, in order to realize Rz axle anti-shake, in order to make Rz axle anti-shake system independent for Rx and Ry's anti-shake system, thus, when Rx, when Ry axle carries out the anti-shake function, Rz's position feedback system is not influenced, thereby effectively improve Rz axle's anti-shake precision, and then more effectively promote the night and take, the picture quality of shooing under the hand trembled the condition during video shooting, further promote consumer and use experience.

In addition, the two support portions 25 of the cardan shaft 2 axially distributed along the first axis are respectively hinged to the outer cradle head support 9, and the two support portions 25 of the cardan shaft 2 axially distributed along the second axis are respectively hinged to the inner cradle head support 5, which can be understood as follows: the two support portions 25 of the cardan shaft 2 axially distributed along the first axis constitute a first rotation axis, so that, when the two support portions 25 are hinged to the outer cradle head support 9, the cardan shaft 2 can rotate along the first rotation axis with respect to the outer cradle head support 9; and cardan shaft 2 constitutes the second rotation axis along the two supporting parts 25 that the axle axial distributes, like this, when these two supporting parts 25 articulate on cloud platform inner support 5, this cardan shaft 2 can rotate along this second rotation axis relative to cloud platform inner support 5, has just also realized that cloud platform inner support 5 can rotate along first rotation axis and second rotation axis respectively relative to cloud platform outer support 9.

On this basis, considering that the camera assembly 20 is elastically connected with the outer cradle head support 9 through the first flexible circuit board 23, and the camera assembly 20 is fixed to the cradle head carrier 10, the camera assembly 20 can rotate along the RZ axis direction along with the cradle head carrier 10 relative to the inner cradle head support 5. Therefore, the rotation of the camera module 103 in the directions of the Rx, Ry, and Rz axes, respectively, is realized. In actual shooting, the shake parameters such as the shake direction and the shake distance of the camera can be acquired, and the camera structure provided by the embodiment of the application is controlled to rotate corresponding rotation amounts along the Rx, Ry and Rz directions respectively, so as to realize anti-shake along the Rx, Ry and Rz axis directions.

In a specific implementation, the specific shape of the first receiving space 905 can be adjusted as required, for example: as shown in fig. 5 and 6a, in the case that the first driving mechanism and the second driving mechanism need to drive the inner cradle head support 5 to move from two opposite sides of the inner cradle head support 5, the first accommodating space 905 may contact at least a first outer side wall, a second outer side wall and a third outer side wall of the inner cradle head support 5, wherein the first outer side wall and the second outer side wall may be two opposite side walls of the inner cradle head support 5, and the third outer side wall is located between the first outer side wall and the second outer side wall.

Of course, in the case that the first driving mechanism and the second driving mechanism only need to drive the inner cradle head support 5 to move from one side wall of the inner cradle head support 5, the first accommodating space 905 may be disposed between the first outer side wall of the inner cradle head support 5 and the first inner side wall of the outer cradle head support 9, and is not limited in detail herein.

In a specific implementation, the head of the camera assembly 20 may extend out of the outer cradle head support 9 through the light-passing hole on the upper side of the outer cradle head support 9, that is, the first driving mechanism and the second driving mechanism may be aligned with the tail of the camera module (i.e., below along the z-axis in fig. 2), so that the electromagnetic driving modules in the first driving mechanism and the second driving mechanism may be disposed in an area far from the head of the cradle head, so as to make more nonmagnetic areas at the head of the cradle head, so that the camera module carrying the cradle head can select more types of driving motors, for example: an Optical Image Stabilization (OIS) camera module can be optionally mounted. Like this, can combine the camera structure that this application embodiment provided along Rx, Ry and Rz direction with, construct as 5 anti-shake camera systems (along X respectively promptly, Y, Rx, Ry and Rz direction's anti-shake), and then can drive camera system respectively and compensate or the combination compensation is carried out to the shake of 5 degrees of freedom, avoid synthesizing motion compensation to have the time difference and the influence that the compensation state can not in time switch over, make the picture of shooing better with the video image quality, especially can more effectively promote the picture quality of shooing under the hand shake condition when shooing night, wholly promote consumer and use the experience.

when current is applied to the second drive coil group 17, an interaction force is generated between the second drive coil group 17 and the second magnet group 15, and the second magnet group 15 drives the cloud platform carrier 10 to rotate along the third axis relative to the inner holder 5 based on the interaction force.

In the embodiment of the present invention, the first yoke and the second yoke are the same yoke 22, the first magnet group 21 is fixed on the outer side of the yoke 22, and the second magnet group 17 is fixed on the inner side of the yoke 22, so that the number of yokes in the camera structure provided in the embodiment of the present invention can be reduced to reduce the volume and reduce the cost. Of course, the first yoke and the second yoke may be different yokes where space and cost allow, and are not particularly limited herein.

In an implementation, as shown in fig. 6c and fig. 7b, a third through hole 2201 may be formed in the bottom of the slot of the second yoke 22, so that the fastening structure 502 extending from the outer sidewall of the cradle head inner support 5 is fastened to the third through hole 2201, that is, the third through hole 2201 can position and fix the second yoke 22.
