Referring to FIG. 7, in some embodiments, the second connecting block 603 is slidably connected to the connecting portion 604.

Referring to FIGS. 6 and 7, the connecting portion 604 includes a first wall 6041, a second wall 6042, a spring 6043, and a second connecting rod 6044. The first wall 6041 and the second wall 6042 face each other. In some embodiment, the first wall 6041 may be a part of the peripheral wall 6023. One end of the second connecting rod 6044 is connected to the first wall 6041, and the other end is connected to the second wall 6042. The second connecting rod 6044 passes through the second connecting block 603. The second connecting block 603 can slide relative to the second connecting rod 6044. The spring 6043 wraps the second connecting rod 6044 and is located between the first wall 6041 and the second connecting block 603. Correspondingly, a surface of the second connecting block 603 has a second protrusion 6031. The second connecting block 603 is connected to the second connecting hole 4021 of the first connecting rod 40 through the second protrusion 6031. As such, when the second connecting end 402 of the first connecting rod 40 moves toward the camera bracket body 602, the first connecting rod 40 can drive the second connecting block 603 to move toward the first wall 6041. Then, the second connecting block 603 pushes the spring 6043, so that the camera bracket body 602 moves away from the driver 201 and is exposed out of the body 10 through the opening 1014. When the second connecting end 402 of the first connecting rod 40 moves away from the camera bracket body 602, the first connecting rod 40 can drive the second connecting block 603 to move toward the second wall 6042. Until the second connecting block 603 meets the second wall 6042, the connecting portion 604 will be pushed to move the camera bracket body 602 toward the driver 201, and is hidden in the body 10 through the opening 1014.

In some embodiments, the first connection hole 4011 and the second connection hole 4021 are all elliptical holes. In other embodiments, the first connection hole 4011 and the second connection hole 4021 may be longitudinal holes.

Working principle of the camera module 30 is:

Referring to FIG. 7, firstly, when the camera module 30 is received in the body 10, the first connecting block 203 is located on the top wall 2021 of the bracket 202, and the first protrusion 2031 is located in the one end of the second connection hole 4021 away from the first connecting 4011. The second connecting block 603 is located at the second wall 6042 of the connecting portion 604, and the second protruding portion 6031 is located at the end of the second connecting hole 4021 away from the first connecting hole 4011.

Under the action of the driver 201, the screw rod 204 is rotated to drive the first connecting block 203 to move toward the first bottom wall 2023. When the first connecting block 203 moves to the middle of the screw rod 204, the first protrusion 2031 moves to an end of the first connecting hole 4011 near the second connecting hole 4021. At the same time, the first connecting end 401 of the first connecting rod 40 moves toward the first bottom wall 2023 by the first connecting block 203, and the second connecting end 402 of the first connecting rod 40 moves toward the first wall 6041. Thus the second connecting block 603 continuously pushes the spring 6043, and the camera bracket body 602 moves away from the driver 201. When the second connecting block 603 moves to the middle of the second connecting rod 6044, the second protrusion 6031 moves to an end of the second connecting hole 4021 near the first connecting hole 4011.

Under the action of the driver 201, the first connecting block 203 continues to move toward the first bottom wall 2023 to press against the first bottom wall 2023. At the same time, the first connecting end 401 of the first connecting rod 40 continues to move toward the first bottom wall 2023 under the driving of the first connecting block 203, and the second connecting end 402 of the first connecting rod 40 continues to move toward the first wall 6041. The second connecting block 603 continues to push the spring 6043, and the camera bracket body 602 moves away from the driver 201, and is exposed out of the body 10 through the opening 1014. At this time, the first protrusion 2031 moves to an end of the first connecting hole 4011 away from the second connecting hole 4021, and the second protrusion 6031 moves to an end of the second connecting hole 4021 away from the first connecting hole 4011.

In some embodiments, when the camera module 30 is to be received in the body 10, the screw rod 204 can be rotated by the driver 201 to drive the first connecting block 203 toward the top wall 2021, until the first connecting block 203 meets the top wall 2021. At the same time, the first connecting end 401 of the first connecting rod 40 moves toward the top wall 2021 under the driving of the first connecting block 203, and the second connecting end 402 of the first connecting rod 40 moves to the second wall 6042. The second connecting block 603 moves toward the second wall 6042 and presses against the second wall 6042 to push the connecting portion 604. Then, the camera bracket body 602 is pushed by the connecting portion 604 toward the driver 201, and is received in the body 10 through the opening 1014.

In the electronic device 100, the first connecting rod 40 makes the connection between the driving component 20 and the camera assembly 60. The camera assembly 60 is received in the body 10, to improve the screen-to-body ratio, but can be deployed and retracted as required.
