Camera ejecting mechanism and mobile terminal

Abstract

An embodiment of the invention relates to a mobile terminal, and the invention discloses a camera ejecting mechanism and a mobile terminal. The camera ejecting mechanism comprises a shell driving a camera to be ejected out of or enter the mobile terminal, wherein the ejecting mechanism comprises a support component, a transmission rod, a cam, and a driving device, the support component supports the camera and is arranged in the shell in a sliding manner, the transmission rod is arranged in the shell in a sliding manner, one end of the transmission rod is connected with the support component, the outer cam surface of the cam props against one end, far from the support component, of the transmission rod, when rotating, the cam drives the transmission rod to move in a straight line along a sliding direction of the support component, and the driving device is connected with the cam so as to drive the cam to rotate. Compared with the prior art, the camera ejecting mechanism has a more compact structure, does not occupy a large space, facilitates ultimate design of the mobile terminal, is convenient to manufacture and assemble, is low-cost, moves reliably and drives stably.

Description

technical field [0001] The embodiments of the present invention relate to a mobile terminal, and in particular to a pop-up mechanism of a camera and a mobile terminal. Background technique [0002] With the popularity of full screens, the placement and use of front cameras has become a prominent issue. At present, the camera of the full-screen device is placed in the housing below the screen, and the telescopic movement of the camera is realized through a custom-made motor-driven screw mechanism to maintain the clarity of the front-facing camera. However, the screw mechanism includes a guide rod, a ball screw, a motor, and a support frame. The camera is arranged on the support frame, the guide rod and the support frame are slidingly fitted, the support frame is fixed on the bearing sleeve of the ball screw, and the motor drives the ball screw The screw rod in the mobile terminal rotates, and the camera is pushed out or enters the housing. This structure allows the camera to...

However, the screw mechanism includes a guide rod, a ball screw, a motor, and a support frame. The camera is arranged on the support frame, the guide rod and the support frame are slidingly fitted, the support frame is fixed on the bearing sleeve of the ball screw, and the motor drives the ball screw The screw rod in the mobile terminal rotates, and the camera is pushed out or enters the housing. This structure allows the camera to achieve linear motion. The transmission process and structure are relatively complicated, and the transmission efficiency is also low. Assembly is difficult, which increases processing and assembly costs, which is not conducive to the extreme design of mobile terminals
