As shown in fig. 1, the present application provides a camera head rotating mechanism, which includes a base 10 and a bracket 20 for carrying a camera head assembly 30, wherein the base 10 and the bracket 20 can rotate relatively. The support 20 is including stretching into the cooperation portion 201 of base 10, and cooperation portion 201 is provided with first spacing subassembly 202, and the base 10 is equipped with along the spacing subassembly 101 of axial complex second with first spacing subassembly 202, and when the support 20 drove camera subassembly 30 horizontal direction rotatory, the spacing structure that first spacing subassembly 202 and the cooperation of the spacing subassembly 101 of second formed limits the axial motion of support 20.

Compared with the prior art, the camera slewing mechanism that this application provided sets up first spacing subassembly 202 through cooperation portion 201 at support 20, is provided with the spacing subassembly 101 of second at the inner wall of base 10, through the spacing subassembly 101 axial cooperation of first spacing subassembly 202 and second, can avoid or reduce the axial range of rocking when support 20 is rotatory relative to base 10, improves camera assembly 30's shooting stability.

In some of these embodiments, at least one of the first stop assembly 202 and the second stop assembly 101 is an annular flange.

Specifically, the first position-limiting component 202 may be an annular flange, and the second position-limiting component 101 may be a plurality of protrusions distributed at intervals; the second position-limiting component 101 may also be an annular flange, the first position-limiting component 202 may be a plurality of protrusions distributed at intervals, or both the first position-limiting component 202 and the second position-limiting component 101 may be annular flanges. As long as the first position-limiting assembly 202 and the second position-limiting assembly 101 are axially matched, when the bracket 20 horizontally rotates, the second position-limiting assembly 101 can apply a downward force to the first position-limiting assembly 202 to limit the axial movement of the bracket 20.

Referring to fig. 1 to 3, the bracket 20 further includes a circular truncated cone 203 in contact connection with the base 10, and the fitting portion 201 is disposed at the bottom of the circular truncated cone 203 and has a radial dimension smaller than that of the circular truncated cone 203 so as to extend into the base 10; the first position-limiting component 202 is an annular flange formed at the lower end of the fitting portion 201 and protruding outward in the radial direction, and the second position-limiting component 101 is a protrusion formed at the inner wall of the base 10 and protruding inward, and the lower end surface of the protrusion is in face-to-face contact with the upper end surface of the annular flange to limit the axial movement of the bracket 20.

In one embodiment, the lower end surface of the projection is a clearance fit with the upper end surface of the annular flange. The friction between the base 10 and the support 20 can be reduced by arranging the lower end face of the protrusion and the upper end face of the annular flange in a clearance fit manner, so that the support 20 can smoothly rotate to drive the camera assembly to rotate. In this application, the clearance between the lower end face of the protrusion and the upper end face of the annular flange is 0.1mm to 0.2 mm. After the bracket 20 is installed on the base 10, if the gap between the lower end surface of the protrusion and the upper end surface of the annular flange is too large, the limiting effect is affected, and the bracket 20 may slightly shake although the axial movement of the bracket 20 may be limited to a certain extent when rotating. If the gap between the lower end surface of the protrusion and the upper end surface of the annular flange is excessively large, horizontal rotation of the bracket 20 may be hindered. In the present application, the fitting clearance between the lower end surface of the protrusion and the upper end surface of the annular flange is set to 0.1mm to 0.2mm, so that the axial movement of the bracket 20 can be well limited, and the bracket 20 can be ensured to drive the camera assembly 30 to smoothly rotate in the horizontal direction.

In a preferred embodiment, the number of the protrusions is 4, 4 protrusions are uniformly distributed on the inner wall of the base 10 at intervals, and the 4 protrusions uniformly distributed at intervals can ensure the axial stability of the bracket 20 when rotating in the horizontal direction, and the cost is low.

In some of these embodiments, the upper end surface of the annular flange is horizontal. The upper end face of the annular flange is a horizontal plane, so that the butt joint surface between the lower end face of the base 10 and the lower end face of the base can be enlarged, the axial movement of the support 20 can be better limited, and the support 20 can rotate more stably. In addition, the upper end face of the annular flange is set to be a horizontal plane, so that mold opening production can be better realized.

In some embodiments, the first limiting member 202 is a first annular flange formed at the lower end of the fitting portion 201 and protruding outward in the radial direction, and the second limiting member 101 is a second annular flange formed at the inner wall of the base 10 and protruding inward, and the lower end of the first annular flange is in face-to-face engagement with the upper end surface of the second annular flange to limit the axial movement of the bracket 20. It will be appreciated that the first stop assembly 202 and the second stop assembly 101 are each provided as an annular flange, providing greater stability of the bracket 20 during horizontal rotation.

In some embodiments, one of the first position-limiting component 202 and the second position-limiting component 101 is an annular groove, and the other is a position-limiting rib clamped in the annular groove.

For example, the first limiting component 202 may be an annular groove formed on the mating portion 201 of the bracket 20, and the second limiting component 101 is a limiting rib formed by inward protruding on the inner wall of the base 10, and when the bracket 20 is mounted on the base 10, the limiting rib is clamped inside the annular groove to limit the movement of the bracket 20 in the axial direction.

In addition, the first limiting component 202 is integrated with the bracket 20, and the second limiting component 101 is integrated with the inner wall of the base 10, so that the production and installation are convenient.
