In one embodiment, the camera mounting assembly 300 may further include a flash 330, a light sensor, or other devices disposed on the mounting base 310 for assisting the camera 320 in photographing, or other functional devices independent of the photographing function of the camera 320 (e.g., an iris recognition module, a face recognition module, a proximity sensor, an ambient light sensor, a microphone, a fingerprint module, etc.). The material of the mounting seat 310 may be, but is not limited to, metal, plastic, stainless steel, or the like.

In an embodiment, with reference to fig. 5 to fig. 7, the mobile terminal 10 is provided with a receiving slot 1311. In one embodiment, the receiving slot 1311 is opened in the body 100. In one embodiment, the receiving groove 1311 is opened on the first side circumferential surface 131 of the body 100. Further, the receiving groove 1311 may be opened in the middle of the first side circumferential surface 131, that is, the receiving groove 1311 is located between the front surface 110 and the rear surface 120. Of course, the receiving groove 1311 may be opened at an edge of the first side circumferential surface 131 close to the rear surface 120.

In an embodiment, the mounting base 310 can move with the camera 320 from a first position (shown in fig. 5) to a second position (shown in fig. 6) and a third position (shown in fig. 7), when the mounting base 310 is in the first position, the mounting base 310 and the camera 320 are accommodated in the accommodating groove 1311, when the mounting base 310 is in the second position, the image capturing surface of the camera 320 is exposed on the side where the display screen 200 is located to be used as a front-facing camera, and when the mounting base 310 is in the third position, the image capturing surface of the camera 320 is exposed on the side where the display screen 200 is located to be used as a rear-facing camera. In an embodiment, the mounting base 310 can rotate into and out of the receiving slot 1311, that is, in the process that the mounting base 310 moves from the first position to the second position and the third position, the mounting base 310 can rotate around the rotation axis to change the orientation of the image capturing surface of the camera 320, so as to switch the camera 320 between the front photographing mode and the rear photographing mode (that is, switch from the second position to the third position), which not only saves the number of the cameras 320, but also realizes panoramic photographing. Wherein the rotation axis 310 is parallel to the first direction.

In one embodiment, as shown in fig. 5, the mounting seat 310 has a top surface 311, and when the mounting seat 310 is in the first position, the top surface 311 of the mounting seat 310 is flush with the side circumferential surface 130, specifically, flush with the first side circumferential surface 131. Therefore, when shooting is not needed, the outer surface of the mobile terminal 10 is not sunken or raised, so that a user can have comfortable holding experience, and meanwhile, the attractiveness of the mobile terminal 10 can be improved. It should be noted that, for the side circumferential surface 130 to be a curved surface smoothly transitioning from the front surface 110 to the rear surface 120, the top surface 311 of the mounting seat 310 may also be designed to be a curved surface capable of engaging with the side circumferential surface 130 to match the external shape of the side circumferential surface 130, so as to further enhance the holding experience and the aesthetic appearance of the mobile terminal 10.

In the mobile terminal 10, when photographing with the camera 320 is required (including front photographing, rear photographing, and panorama photographing), the mount 310 can move out of the housing 1311 with the camera 320 to perform photographing. After the shooting is finished, the mounting seat 310 carries the camera 320 to move into the accommodating groove 1311, so that the space of the side where the display screen 200 is occupied by the camera 320 can be eliminated, the coverage rate of the display screen 200 on the front surface 110 is increased, and the screen occupation ratio of the display screen 200 is improved. In an embodiment, the mounting seat 310 is movably disposed in the receiving slot 1311 along a first direction, that is, the mounting seat 310 is slidably engaged with the receiving slot 111. In this way, the stability of the mounting seat 310 during the process of extending out of or into the receiving groove 1311 can be increased. It is understood that in other embodiments, the mounting seat 310 and the wall of the receiving groove 1311 may not be in direct contact.

The camera mounting assembly 300 and the drive mechanism assembly 400 can be combined to form a mounting drive assembly. With continued reference to fig. 5-7, in one embodiment, the driving mechanism assembly 400 includes a driver 410 connected to the body 100 and a transmission mechanism 420. The transmission mechanism 420 is disposed between the output end 411 of the driver 410 and the mounting seat 310, the driver 410 may be a motor, and the driver 410 can drive the mounting seat 310 to rotate into and out of the receiving slot 1311 through the transmission mechanism 420. In one embodiment, the driver 410 is configured to drive the mounting base 310 via the transmission mechanism 420 from the first position to the second position and the third position. When the mounting seat 310 is at the first position, as shown in fig. 5, the camera 320 is accommodated in the accommodating groove 1311; when the mounting seat 310 is in the second position, as shown in fig. 6, the image capturing surface of the camera 320 is exposed at the side of the display screen 200, and is used as a front camera; when the mounting seat 310 is in the third position, as shown in fig. 7, the image capturing surface of the camera 320 is exposed at the side facing away from the display screen 200, and is used as a rear camera. In the process that the mounting base 310 moves from the first position to the second position and the third position, the driver 410 can drive the mounting base 310 to rotate around the rotation axis (the rotation axis is parallel to the first direction) through the transmission mechanism 420, so as to change the orientation of the image collecting surface of the camera 320, when the mounting base 310 is located at the second position, the image collecting surface of the camera 320 is exposed at one side of the display screen 200, and when the mounting base 310 is located at the third position, the image collecting surface of the camera 320 is exposed at one side of the display screen 200.

It should be noted that, in the process that the mounting base 310 moves from the first position to the second position, the rotation angle of the mounting base 310 may be determined according to the orientation of the image capture surface of the camera 320 when the mounting base 310 is located at the first position and the distance between the first position and the second position, so that when the mounting base 310 is located at the second position, the image capture surface of the camera 320 is just exposed to the side of the display screen 200, thereby implementing front-end shooting; during the process that the mounting seat 310 moves from the second position to the third position, the mounting seat 310 can rotate 180 degrees around the rotating shaft to realize rear shooting; of course, the mounting seat 310 may also continue to rotate 180 degrees, i.e. 360 degrees, around the same direction, thereby realizing 360-degree panoramic shooting. In addition, the mounting base 310 can be retracted into the receiving groove 1311 to hide the image capture surface of the camera 320. For example, the mounting seat 310 may be automatically retracted into the receiving slot 1311 by the driving mechanism assembly 400, and the mounting seat 310 may be manually retracted. Thus, the extension and rotation of the mount 310 can be realized by one driver 410.

In an embodiment, referring to fig. 5, 8 and 9, the transmission mechanism 420 includes a driving member 421 connected to the output end 411 of the driver 410, and a driven member 422 disposed on the mounting seat 310 and connected to the driving member 421.

In one embodiment, the driving member 421 includes a first screw 421, the driven member 422 includes a second screw 422, the first screw 421 is engaged with the second screw 422, and the first screw 421 and the second screw 422 both extend along a first direction, where the rotation axis is parallel to the extending direction of the second screw 422. When the second screw 422 is a standard cylindrical rod-shaped structure, the rotation axis is the central axis of the second screw 422. It will be appreciated that in other embodiments, the transmission 420 is a worm and gear arrangement, where the driving member 421 comprises a worm gear, and the driven member 422 comprises a screw, the worm gear being engaged with the screw, the screw extending in a first direction, and the axis of rotation of the worm gear being perpendicular to the first direction (e.g., extending in a second direction). It should be noted that the first screw 421 and the second screw 422 may adopt a hollow structure design, so as to reduce the material and weight of the first screw 421 and the second screw 422, and save the cost, and in addition, the first screw 421 and the second screw 422 of the hollow structure are beneficial to routing of the functional devices of the camera mounting assembly 400.

In one embodiment, the drive mechanism assembly 400 includes a gear box 430 connected between the output 411 of the drive 410 and the first screw 421 to reduce the starting inertia of the drive 410 (e.g., a motor), achieve greater output torque, reduce the cost and power consumption of the drive 410.

An example of a possible way in which the drive mechanism assembly 400 described above controls the mounting of the drive assembly 300 is now given:

for example, a trigger key may be provided on the side circumferential surface 130 of the body 100. The trigger key connects to a motherboard within the mobile terminal 10. When a user presses or touches the trigger key, the trigger key sends a trigger signal to a processor on the motherboard, and the processor controls the driving mechanism assembly 400 so that the mounting base 310 extends out of or into the receiving groove 1311 under the control of the driving mechanism assembly 400. In an embodiment, pressing the trigger key once can make the mounting base 310 extend out of the receiving slot 1311 from the first position to the second position under the control of the driving mechanism assembly 400, so as to realize front shooting of the camera 320, and at this time, the driving mechanism assembly 400 stops working. When the user presses the trigger key once again, the driving mechanism assembly 400 continues to operate, and at this time, the mounting base 310 may be moved from the second position to the third position under the control of the driving mechanism assembly 400, so as to implement the conversion between the front camera function and the rear camera function of the camera 320, or implement panoramic shooting, and at this time, the driving mechanism assembly 400 stops operating again. When the user presses the trigger key again, the driving mechanism assembly 400 continues to operate, and at this time, the mounting seat 310 may be retracted into the receiving groove 1311 to the first position under the control of the driving mechanism assembly 400. Of course, the number of the triggering keys may be three, the first triggering key is used to extend the mounting base 310 out of the receiving slot 1311 to the second position under the control of the driving mechanism assembly 400, the second triggering key is used to move the mounting base 310 from the second position to the third position under the control of the driving mechanism assembly 400, and the third triggering key is used to retract the mounting base 310 into the receiving slot 1311 to the first position at any time under the control of the driving mechanism assembly 400.

In other embodiments, the triggering key may also be a touch icon disposed on the display screen 200, and clicking the touch icon can send a related touch signal to a processor on the motherboard, and the processor receives the touch signal and executes a corresponding command according to the control signal, so that the driving mechanism assembly 400 drives the mounting base 310 to extend out of or into the receiving slot 1311.

For example, the trigger key may be a front photograph icon, a rear photograph icon, a panorama photograph icon (a panorama angle may be manually selected), and an end photograph icon provided in the display screen 200. When the front shooting icon is touched, the front shooting icon sends a first trigger signal to the processor of the motherboard, and the processor receives the first trigger signal and controls the driving mechanism assembly 400 to drive the mounting seat 310 to extend out of the accommodating groove 111 from the first position to the second position, so that the camera 320 can perform front shooting under the shooting signal. When the rear shooting icon is touched, the rear shooting icon sends a second trigger signal to the processor of the main board, and the processor receives the second trigger signal and controls the driving mechanism assembly 400 to drive the mounting seat 310 to move to the third position, so that the camera 320 can carry out rear shooting under the shooting signal. When the panorama shooting icon is touched, the panorama shooting icon sends a third trigger signal to the processor of the motherboard, the processor receives the third trigger signal and controls the driving mechanism assembly 400 to drive the mounting seat 310 to extend out of the accommodating groove 1311 so as to realize rotation of the panorama angle selected by the user, and at the moment, the user can stand still, namely, panorama shooting can be realized. When the shooting of the icon is finished by touching, the shooting-finished icon sends a fourth trigger signal to the processor of the motherboard, and the processor receives the fourth trigger signal and controls the driving mechanism assembly 400 to drive the mounting seat 310 to extend into the accommodating groove 1311.
