Referring to fig. 9 and 10, fig. 9 is a schematic perspective view of a driving assembly of the camera device with a cover of a nut bracket removed, and fig. 10 is a schematic perspective view of the driving assembly of the camera device with another view angle with the cover of the nut bracket removed. The nut bracket 514 is generally "L" shaped. The nut bracket 514 is sleeved on the screw 513 and is in threaded connection with the screw 514. The nut bracket 514 includes a threaded portion 5141, a mounting portion 5143, and a cover 5145 (shown in fig. 8). The screwing part 5141 is sleeved on the screw rod 513 and screwed with the screw rod 514. The mounting portion 5143 is fixedly connected to the threaded portion 5141. The mounting portion 5143 has a generally trough-like configuration. The mounting portion 5143 includes a first mounting portion 5144, a second mounting portion 5145, and a third mounting portion 5147. The second installation portion 5145 and the third installation portion 5147 are formed by two ends of the first installation portion 5144 protruding and extending in the same direction, the first installation portion 5144 is fixedly connected to the screw connection portion 5141, and the third installation portion 5147 is disposed adjacent to the second installation portion 5115. The cover 5145 is fixed to the screw connection portion 5141 and the mounting portion 5143.

The elastic member 517 abuts the connecting member 516 against the second installation portion 5145 of the installation portion 5143, when the camera module 53 is exposed outside the mobile terminal 100, the camera module 53 can retract into the accommodating cavity 33 due to external force, for example, when the mobile terminal 100 is knocked down, the camera module 53 retracts into the accommodating cavity 33 along the guide rod 515 due to external force, so as to be effectively protected by the housing 30 and not damaged, thereby prolonging the service life of the camera device 50. In addition, the elastic member 517 can buffer when the mobile terminal 100 is impacted by external force, so as to further protect the camera device 50 and prevent the camera device 50 from being damaged. If the external force is an external force that the user intends to press the camera shooting assembly 53 into the recycling cavity 33 in a pressing manner, the elastic action of the elastic member 517 can improve the user experience of the user in the process of applying the force, so that the user feels not hard when pressing the camera shooting assembly 53. The cover 5145 covers the screw portion 5141, the installation portion 5143 and the elastic member 517, and is used for preventing other structures of the mobile terminal 100 from interfering with the movement of the elastic member 517. In an embodiment, the nut bracket 514 may omit the cover 5145.

In one embodiment, the mounting portion 5143 can omit the second mounting portion 5145 and the third mounting portion 5147 which are oppositely disposed, the connecting member 516 is fixed on the nut bracket 514, the elastic member 517 is elastically compressed between the first mounting portions 5112 of the fixing bracket 511, the elastic member 517 is used for providing an elastic assisting force for the camera assembly 53 to face the direction of the opening 31, when the camera assembly 53 is completely accommodated in the accommodating cavity 33, i.e., when the mobile terminal 100 does not receive the shooting requirement of the user, the driving member 512 does not drive the screw rod 51 to move, and the elastic member 517 is elastically compressed between the extending portion 5163 of the connecting member 516 and the third mounting portion 5147. When the mobile terminal 100 starts the driving part 512 in response to the shooting requirement of the user, under the elastic assistance of the elastic part 517, the moving speed of the camera 53 in the direction of the opening 31 can be increased, so that the camera extends out of the opening as soon as possible, and the mobile terminal can quickly and effectively respond to the shooting requirement of the user, thereby improving the working efficiency of the mobile terminal 100 and the user experience.

Referring to fig. 11, fig. 11 is a perspective view of another view angle of a partial structure of the image capturing device. The drive assembly 51 also includes a bearing 518. One end of the screw 513, which is far away from the driving member 512, is rotatably connected with the connecting hole 5117 of the second mounting portion 5113 through the bearing 518.

The driving assembly 51 further includes a clip 519, wherein the clip 519 is sleeved on the bearing 518 and fixedly received in the connecting hole 5117 of the second mounting portion 5113 to prevent the bearing 518 from loosening. In this embodiment, the clip 519 is spot-welded to the second mounting portion 5113, so that the length of the second mounting portion 5113 can be reduced and the strength of the fixing bracket 5111 can be increased.

Referring to fig. 6, 7 and 8 again, the camera assembly 53 includes a camera bracket 531 and a camera 533. The camera bracket 531 is fixedly connected to the fixing portion 5161 of the connecting member 516. The camera 533 is fixed to the camera bracket 531. The driving member 512 can drive the screw 513 to rotate, so as to drive the camera 533 to extend out of the housing 30 from the opening 31.

In this embodiment, when the driving member 512 drives the screw 513 to rotate counterclockwise, the camera 53 moves along the guide rod 512 toward the opening 31, please refer to fig. 12, fig. 12 is a schematic diagram of a state where the first limiting member of the camera 53 abuts against the second end of the limiting groove, and when the first limiting member 55 abuts against the second end 5315, the camera 533 of the camera 53 extends out of the housing 30 from the opening 31 to reach the preset shooting position; when the driving member 512 drives the screw 513 to rotate clockwise, the camera module 53 retracts into the housing 30 along the guiding rod 512, as shown in fig. 6 and 7, when the first limiting member 55 abuts against the first end portion 5313, the camera module 53 is completely accommodated in the accommodating cavity 33. The movement stroke of the camera 53 is limited by the limiting groove 5311 and the first limiting member 55, so that the camera 53 is prevented from being damaged. It is understood that the rotation direction of the driving member 512 driving the screw 513 is not limited, for example, when the driving member 512 drives the screw 513 to rotate clockwise, the camera module 53 can extend out of the housing 30 from the opening 31, and when the driving member 512 drives the screw 513 to rotate counterclockwise, the camera module 53 can retract into the housing 30 from the opening 31 and be accommodated in the accommodating cavity 33.

In an application scenario of the mobile terminal 100, when the camera module 53 of the camera device 30 extends out of the opening 31 to a predetermined shooting position, if the camera device 30 needs to be closed, the camera module 53 can be pressed by an external force to retract the camera module 53 into the accommodating cavity 33, for example, a user can press the camera module 53 by hand to retract the camera module 53 into the accommodating cavity 33, which is convenient for the user to operate, and is also beneficial to protecting the camera device 50 and avoiding damaging the camera device 50 when the user carelessly touches the mobile terminal 100.
