It is to be understood that the described embodiments are merely exemplary of the invention, and not restrictive of the full scope of the invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The technical solutions disclosed in the embodiments of the present invention are described in detail below with reference to the accompanying drawings.
Referring to fig. 1 to fig. 3, an embodiment of the invention discloses a mobile terminal, which includes a housing 100, a camera 200, a circuit board 300, a first driving mechanism 400, and a second electrical connection portion 500.
The case 100 is a peripheral member of the mobile terminal and provides a mounting base for other constituent members of the mobile terminal. The camera 200 can move in and out of the housing 100. In general, a frame (may be a middle frame) of the casing 100 is provided with a through hole, and the camera 200 can move in and out of the through hole, thereby achieving the purpose of moving in and out of the casing 100. When the camera 200 is extended out of the through hole, it can be ready for photographing and then photographing. When the camera 200 retracts into the through hole and is located in the inner cavity of the housing 100, the purpose of folding the camera 200 can be achieved.
In this embodiment, the camera 200 includes a first electrical connection portion 210, and the first electrical connection portion 210 is used to be electrically connected to a power device (such as a circuit board 300) in the mobile terminal, so as to supply power to the micro camera 200. The camera 200 can perform a photographing operation after being powered on.
Specifically, the circuit board 300, the first driving mechanism 400, and the second electrical connection portion 500 are all disposed within the housing 100. The second electrical connection portion 500 is electrically connected to the circuit board 300, and the circuit board 300 can supply power for the shooting of the camera 200. In general, the circuit board 300 may be a main board of the mobile terminal or a sub-board of the mobile terminal. In this embodiment, the second electrical connection portion 500 is disposed inside the housing 100 and can move inside the housing 100.
The first driving mechanism 400 is connected to the second electrical connection portion 500, and the first driving mechanism 400 is used for driving the second electrical connection portion 500 to move, so that the second electrical connection portion 500 is connected to and disconnected from the first electrical connection portion 210. In a specific driving process, when the camera 200 extends out of the housing 100, the first driving mechanism 400 drives the second electrical connection portion 500 to move to a position electrically contacting with the first electrical connection portion 210, and finally, the electrical connection between the second electrical connection portion 500 and the first electrical connection portion 210 is achieved. In this case, the camera 200 can be electrically connected to the circuit board 300 through the first electrical connection portion 210 and the second electrical connection portion 500, and thus power is supplied from the circuit board 300. When the camera 200 retracts into the housing 100, the first driving mechanism 400 drives the second electrical connection portion 500 to disconnect from the first electrical connection portion 210, so as to cut off the power supply of the circuit board 300.
