Specifically, the lower portion of the left side surface 43a of the camera mounting base 40 is provided with a left roller 61 and a right roller 62; the left roller 61 and the right roller 62 are disposed to protrude from the left side 43a and the right side 43b of the camera mount 40, respectively.

The side surface of the display 1 comprises a first frame 1a and a second frame 1b which are adjacent; the abutment of the first frame 1a and the second frame 1b constitutes said corner (typically a transitional circular arc) of the display 1.

As shown in fig. 4, the linkage structure is seen from the back of the display, and as shown in fig. 4, the display 1 and the screen swinging and connecting seat 20 swing to the right (clockwise), and the camera mounting seat 40 abuts against the first frame 1a of the display 1 through the right rolling member 62 and moves relatively along the first frame 1a of the display 1.

When the camera mounting base 40 relatively moves through (or is called as over) the corner, the camera mounting base 40 sequentially abuts against the display 1 through the right rolling member 62, the sliding working surface 41 and the right rolling member 62.

The structure of the invention is particularly simple, the camera mounting seat 40 tends to move downwards under the action of the self gravity, and/or the gravity of the movable rail 32 and/or the reset force of the reset piece, so that the camera can always move along the high-difficulty track of the relative movement of the edge of the display 1 in a fitting manner when the display 1 and the screen swinging connecting seat 20 are swung and expected by a user by adopting an extremely simple structure. In the swinging process of the display 1, the camera cannot be separated from the frame of the display 1 midway and cannot turn over along with the display 1, the appearance looks very beautiful and elegant, and the moving track 32 of the camera expected by a user is realized.

In the above technical solution, it is more preferable that, as shown in fig. 5 and 6, the rolling member 60 is provided not to protrude downward from the sliding surface 41 in the height direction. That is, in the high east direction, the sliding face 41 is flush with the lowest point of the outer circumferential rolling face of the rolling member 60, or the sliding face 41 is disposed below the rolling member 60. When the display 1 is not rotated and the first frame is in a horizontal state, the camera mounting seat 40 abuts against the first frame of the display 1 through the sliding working surface 41.

For convenience of description, the top surface of the display directly above is defined as a first frame, not a fixed frame for defining the display.

When the rolling member 60 relatively moves from the first frame 1a to the second frame 1b through the corner of the display, that is, at the moment when the rolling member 60 relatively moves through the end of the first frame 1a, the first frame 1a cannot support the camera mount 40 through the rolling member 60, and at this moment, the second frame 1b cannot immediately continue to support the camera mount 40 through the rolling member 60; in the height direction, when the rolling members 60 are provided to protrude downward from the slide face 41, the camera mount 40 drops at this moment, and the corner of the display 1 abuts on the slide face 41 (or the bottom face of the camera mount 40), thereby causing vibration and noise problems.

According to the invention, the rolling piece is arranged above the sliding working surface 41 in a shrinking manner or the bottom of the rolling piece is flush, so that the problems of instant falling and vibration of the camera mounting seat 40 can be effectively avoided when the corner is crossed, and the linkage of the camera mounting seat 40 is smoother.

In the above solution, it is more preferable that the center of the rolling member 60 is not protruded outward from the side 43 of the camera mounting seat 40 in a projection plane perpendicular to the pivot axis of the screen swinging and connecting seat 20. Thereby facilitating the provision of a smooth transition contour 42 between the flank 43 and the sliding running surface 41.

The rolling elements 60 are preferably rolling bearings. Wherein, the bearing outer ring can be rotationally arranged and is attached to the frame of the display 1. Of course, there are many other forms of rolling element 60, such as a roller, a rotatably disposed axle, etc.
