Referring to fig. 1 to 3, a lifting and overturning assembly according to an embodiment of the present application will be described. The lifting turnover assembly comprises a shell 1, a lifting seat 2, a lifting driving unit 6, a rotating shaft 3, a turnover seat 4 and a rack 5. Wherein, the housing 1 is provided with a groove 11 along a first direction, and the groove 11 can be substantially in a strip shape. Here, the first direction may be a Y-axis direction in the drawing. The lifting seat 2 is slidably mounted on the housing 1 along a first direction. Here, casing 1 is last to open along the first direction and to be equipped with the constant head tank of holding lift seat 2, and lift seat 2 can be along first direction reciprocating motion in the constant head tank, and the constant head tank can play the directional guide effect to lift seat 2, prevents that lift seat 2 from taking place the offset at reciprocating motion's in-process.

Referring to fig. 3 to 5, the rotating shaft 3 is rotatably mounted on the lifting base 2, and the gear 31 is mounted on the rotating shaft 3. Here, the central axis of the rotating shaft 3 may be in a second direction (i.e., an X-axis direction in the drawing), the first direction being perpendicular to the second direction. The turning base 4 is sleeved on the rotating shaft 3, and when the rotating shaft 3 rotates, the turning base 4 can be driven to rotate together. The rack 5 is slidably mounted on the lifting seat 2 along a first direction, the rack 5 is meshed with the gear 31, and the rack 5 is provided with a resisting seat 51 extending into the groove 11.

Referring to fig. 3 and 11, when the lifting driving unit 6 drives the lifting base 2 to move upward along the first direction, the lifting base 2 extends out of the housing 1 until the stopping base 51 on the rack 5 stops against the end wall of the groove 11 along the first direction. Here, the groove 11 has two opposite side walls in the first direction, which are divided into a top wall and a bottom wall, and the rack 5 can be engaged with and abutted against the top wall of the groove 11. Along with the lifting seat 2 continues to rise, because the lifting seat 2 drives the rotating shaft 3 and the gear 31 to continue to rise, the rack 5 moves relative to the gear 31 due to the matching of the retaining seat 51 and the groove 11, so that the rotating shaft 3 and the turnover seat 4 can be driven to rotate, and the camera angle of the camera 8 on the turnover seat 4 can be adjusted.

In an embodiment, please refer to fig. 7 and 8, as a specific implementation manner of the lifting turnover assembly provided in the embodiment of the present application, the number of the turnover seats 4 is multiple, and the multiple turnover seats 4 are divided into two groups; the gear 31 is arranged in the middle of the rotating shaft 3, and the two groups of overturning seats 4 are respectively arranged on two sides of the gear 31. Specifically, the number of the turnover seats 4 may be even, and the even number of the turnover seats 4 are equally divided into two groups. This structure, two sets of upset seats 4 symmetric distribution are in the both sides of gear 31, and when rack 5 drove gear 31 and rotate, can guarantee that the rotation synchronism of two sets of upset seats 4 on the axis of rotation 3 is good, does not have the hysteresis quality defect.

In one embodiment, as a specific implementation manner of the lifting turnover assembly provided in the embodiment of the present application, the number of the turnover seats 4 is two, and the maximum rotation angle of one turnover seat 4 is greater than that of the other turnover seat 4.
