Based on the above mobile terminal hardware structure and communication network system, various embodiments of the present application are provided.

Referring to fig. 3, the rotary shooting mechanism 10 according to the embodiment of the present application includes a camera module 1, a rotary frame 200, a fixing frame 300, a rotary link 400, and a motor 500. The rotary shooting mechanism 10 is fixed on the housing 30, the housing 30 can be located at any position in the mobile terminal 100, and the housing 30 is used for carrying the rotary shooting mechanism 10, so that the rotary shooting mechanism 10 can be kept stable relative to the mobile terminal 100. In some embodiments, the housing 30 may serve as an internal structure of the mobile terminal 100, such as a middle frame, a circuit board, etc., and the present application provides the rotary photographing mechanism 10 to be accommodated inside the mobile terminal 100. In other embodiments, the housing 30 may be implemented as a housing of the mobile terminal 100, and the rotary photographing mechanism 10 may be disposed outside the mobile terminal 100.

With continued reference to the rotary camera mechanism 10 shown in fig. 3, the motor 500 provides a power source for the rotary camera mechanism 10. The motor 500 includes a stator 501 and a rotor 502, the stator 501 is fixedly connected to the fixing frame 300, and the rotor 502 is fixedly connected to the rotating link 400. The rotary connecting rod 400 includes two opposite ends, one end of which is fixedly connected to the rotor 502, and the other end of which, i.e., the end away from the rotor 502, is also rotatably connected to the camera module 1. Please refer to the schematic structural diagram of the rotary shooting mechanism 10 in fig. 4 at another angle of view, in the schematic structural diagram, the rotation axis phi of the camera module 1 and the rotor 502₂Forming a first inclination angle alpha. Thus, the rotor 502 of the motor 500 is rotated about its axis of rotation phi₂While rotating, the rotating link 400 also rotates around the rotation axis phi of the rotor 502₂Rotate and simultaneously drive the camera module 1 to rotate around the rotating shaft phi of the rotor 502₂And (4) rotating. Because of the rotational connection relationship between the rotating link 400 and the camera module 1, the camera module 1 rotates around the rotation axis phi of the rotor 502₂While rotating, the rotary connecting rod 400 can move forwardThe row rotates.

Referring to the schematic structural diagram of the rotating shooting mechanism 10 shown in fig. 5 at another viewing angle, the rotating frame 200 includes a first side 210 and a second side 220 adjacent to each other. The camera module 1 is rotatably connected to the first side 210, and the fixing frame 300 is rotatably connected to the second side 220. A first rotation axis 211 is disposed between the camera module 1 and the first side 210, and a second rotation axis 222 is disposed between the camera module 1 and the fixing frame 300 and the second side 220. The first rotation axis 211 and the second rotation axis 222 form a first included angle γ therebetween. Therefore, the camera module 1 has two rotational degrees of freedom with the fixed frame 300 through the rotational connection relationship of the rotating frame 200, and the two rotational degrees of freedom are arranged at an included angle. That is, the camera module 1 forms a universal connection with the fixing frame 300 through the rotating frame 200.

In the process that the motor 500 drives the camera module 1 to rotate through the rotating link 400, because the stator 501 of the motor 500 is fixedly connected with the fixing frame 300 and the camera module 1 can also rotate relative to the rotating link 400, the camera module 1 can keep the rotating shaft phi relative to the rotor 502 under the action of the universal connection formed by the rotating frame 200 and the fixing frame 300₂Forming a posture of a first inclination angle alpha. That is, the motor 500 drives the rotary connecting rod 400 to drive the camera module 1 to rotate around the rotating shaft phi of the rotor 502₂In the process of rotation, the camera module 1 always keeps the rotating shaft phi with the rotor 502₂Forming a posture of a first inclination angle alpha.

Therefore, in the working process of the rotary shooting mechanism 10, the camera module 1 can be driven by the motor 500 to rotate around the rotating shaft phi of the rotor 502 at a fixed inclination angle₂Rotate a week or bigger scope, continuously gather the picture by control camera module 1 simultaneously, sew up through the picture that will make a video recording module 1 and gather in different rotatory position at last, obtain the image that the angle of vision is bigger. Because the rotation axis phi of the camera module 1 relative to the rotor 502₂At a fixed tilt angle, the tilt angle of the image captured by the camera module 1 in different rotational orientations is also kept constant with respect to the mobile terminal 100. That is, the rotational photographing mechanism 10 of the present application can utilize a relatively small angle of viewThe camera module 1 realizes the wide-angle shooting effect in the traditional sense, even realizes special shooting effects such as a spherical curtain and a fish eye, and can not generate large distortion at the edge of an image obtained by sewing. The rotary shooting mechanism 10 can utilize the camera module 1 with relatively low cost to realize the wide-angle shooting effect, can ensure relatively high imaging quality, and improves the user use experience.

Referring to fig. 4, the camera module 1 has an optical axis

Optical axis

Axis of rotation phi with rotor 502₂A first inclination angle alpha is formed between the first and second inclined angles, and the first inclination angle alpha is an acute angle and satisfies the following conditions: alpha is more than or equal to 15 degrees and less than or equal to 45 degrees.

Specifically, in the present embodiment, the optical axis of the camera module 1 is defined

Axis of rotation phi with rotor 502₂A first inclination angle α is formed between the first and second imaging modules, that is, the camera module 1 can maintain an inclined state at a certain angle when performing rotation shooting, and the inclination angle is between 15 ° and 45 °. Preferably, when the angle of the first inclination angle α is 30 °, the image sharpness and image reality of the image captured by the camera module 1 are better. And when the camera module 1 has the posture of the first inclination angle alpha, the camera module 1 can increase the shooting angle during the rotation shooting and can increase the field angle of the rotation shooting mechanism 10 at the same time.

In an embodiment, referring to fig. 6, the image capturing module 1 has a first angle of view β, and the first tilt angle α needs to be larger than the first angle of view β, and the two may also satisfy the following condition: beta/2 is more than or equal to alpha.

Specifically, in the present embodiment, the optical axis of the camera module 1

And rotatingAxis of rotation phi of the sub 502₂The first inclination angle α formed therebetween is an initial inclination state of the camera module, and the camera module 1 in this embodiment has a first field angle β, as can be seen from the figure, when the condition β/2 is satisfied between the first inclination angle α and the first field angle β, which is greater than or equal to β, it can be ensured that the pictures shot by the camera module 1 in the rotation process are partially overlapped, and the overlapping angle is: beta/2-alpha. The existence of the overlapping angle can ensure that the shot picture of the camera module 1 has integrity after the camera module rotates to shoot. If the first angles of view β of the camera module 1 do not overlap partially in the rotation process, the center of the combined angle of view is also empty, that is, the center of the photographed image is empty, so that the integrity of the image cannot be guaranteed.

Referring again to fig. 5, in one embodiment, the first included angle γ is a right angle.
