ABSTRACT:
A magnetic sliding door structure comprises a first and a second magnetic elements attracting each other and disposed on a shell body of a camera and a sliding door, a linkage member disposed below the sliding door, and a third magnetic element disposed at two ends of the linkage member. The third magnetic element repels from the first and second magnetic elements. When one end of the linkage member tilts, the third magnetic element at the other end will enter between the first magnetic element and the second magnetic element to make the sliding door slide toward one side through the repulsive forces between them. This sliding door structure functions based on the physical properties of magnet to avoid complicated gear and rack structures and lower the manufacturing difficulty and cost. Moreover, electric power consumption in the prior art can be saved to increase the standby time of camera.
