Description

Technical Field

[0001] The utility model relates to the technical field of photographic equipment, in particular to a micro camera base structure. Background Art

[0002] The mobile phone camera is the module responsible for the camera function of the mobile phone. In order for the mobile phone camera to work properly, the mobile phone camera motor is indispensable. The mobile phone camera widely uses the voice coil motor to realize the autofocus function, so that the photo presents a clear image. The voice coil motor will drive the lens to the best imaging point when it is powered on. The central camera motor is also an open-loop motor. The difference is that the starting position of the actuator is in the middle of the motor stroke, and the focusing action is accelerated by shortening the moving distance. The main principle is to control the stretching position of the spring sheet by changing the DC current of the coil in the motor in a permanent magnetic field, so as to drive the carrier to move up and down, so that the lens moves with it, and the camera function can operate normally. However, after a long period of use, the connection between the components of the mobile phone will inevitably become loose, and dust and small impurities will enter the interior of the camera motor, which is easy to cause dust in the picture and affect the normal use of the camera function.

The frame 3 is a rectangular frame with a width smaller than the base plate 1, which is convenient for installation so that the motor shell is stuck above the base plate 1 without shaking, and limiting columns 4 are symmetrically provided on the four corners of the frame 3, and triangular connecting areas are provided on the inner side of the surface of the frame 3 corresponding to the position of the limiting columns 4. Positioning columns 6 are symmetrically provided on the inner side of the upper part of the frame 3 corresponding to the position of the limiting columns 4. The positioning columns 6 are used to position the lower spring piece, and the protruding setting can facilitate alignment and connection. Four raised buffer blocks 11 are symmetrically provided on the inner side of the upper part of the base plate 1 corresponding to the position of the frame 3. The buffer blocks 11 can play a buffering role when the upper motor carrier moves up and down.

Those grooves of different shapes have the function of accommodating impurities, so that impurities cannot move at will, thereby avoiding interference with the normal use of the camera function. The bottom surface of the base plate 1 is provided with a plurality of grooves of different sizes and shapes, which are convenient for aligning the position when assembling the camera motor.
