In order to solve the technical problem, the utility model discloses the technical scheme who adopts is:

the adjusting screw for the automobile skylight motor comprises an adjusting screw body, wherein a bearing containing cavity with a downward opening is formed in the bottom end of the adjusting screw body, a transmission part is arranged in the bearing containing cavity, and the adjusting screw is rotatably connected with a motor shaft through the transmission part.

Preferably, the transmission part comprises a bearing, the outer diameter of the outer ring of the bearing is matched with the inner diameter of the bearing cavity, and the inner diameter of the inner ring of the bearing is matched with the outer diameter of a motor shaft of the automobile skylight motor.

Preferably, the side of the adjusting screw body is provided with an external thread, the external thread is matched with an internal thread hole on the gear box, and the internal thread hole is coaxial with the motor shaft.

Preferably, the profile of the external thread comprises any one of triangular, rectangular, trapezoidal, saw-tooth.

Preferably, the top end of the adjusting screw body is provided with a profiled groove.

Preferably, the type groove comprises any one of a cross groove, a straight groove, an inner triangular groove, an inner hexagonal groove and a cross groove.

Compared with the prior art, the utility model discloses the beneficial effect who reaches: the bottom of adjusting screw body is equipped with the bearing that the opening is decurrent and holds the chamber, and the bearing holds the intracavity and is equipped with the bearing, and adjusting screw accessible bearing is connected with the motor shaft rotation of sunroof motor, avoids high-speed pivoted motor shaft and adjusting screw to produce violent friction and cause wearing and tearing. The bearing accommodating cavity has the radial and axial limiting effects on the top end of the motor shaft, so that the bearing accommodating cavity can play a good role in supporting when the bearing accommodating cavity is subjected to external impact vibration, and the phenomenon that the distance between the worm and the worm wheel is too large or too small is avoided; the adjusting screw can also be rotated through the cross groove to move along the axial direction, so that the axial position of the fine adjustment worm is driven, the position deviation of the worm and the worm wheel in the axial direction is corrected, and the problem that the worm and the worm wheel cannot be meshed accurately is effectively solved.

Detailed Description

The present invention will be further described with reference to the accompanying drawings. The following examples are only for illustrating the technical solutions of the present invention more clearly, and the protection scope of the present invention is not limited thereby.

It should be noted that, in the description of the present invention, the terms "front", "rear", "left", "right", "upper", "lower", "inner", "outer", etc. indicate the directions or positional relationships based on the directions or positional relationships shown in the drawings, and are only for convenience of description of the present invention but do not require the present invention to be constructed and operated in a specific direction, and thus, should not be construed as limiting the present invention. As used in the description of the present invention, the terms "front," "back," "left," "right," "up," "down" and "in" refer to directions in the drawings, and the terms "inner" and "outer" refer to directions toward and away from, respectively, the geometric center of a particular component.

The utility model provides an adjusting screw for a motor of an automobile skylight, as shown in fig. 1 and fig. 2, which are a structural diagram and a front view of the embodiment of the utility model respectively, comprising an adjusting screw body, wherein the bottom end of the adjusting screw body is provided with a bearing accommodating cavity 3 with a downward opening, and a transmission part is arranged in the bearing accommodating cavity 3; the side of adjusting screw body is equipped with external screw thread 2, the top of adjusting screw body is equipped with type groove, type groove can adopt cross 1, in the straight line groove, in the triangle groove, in the hexagonal groove, in the rice word groove arbitrary one, in this embodiment, cross 1 is adopted in the type groove.

More specifically, as shown in fig. 3, is an assembly view of an embodiment of the present invention. The structure and the operation principle of the present invention will be further explained with reference to fig. 3. The transmission component is a bearing, and the outer diameter of the outer ring of the bearing is matched with the inner diameter of the bearing accommodating cavity 3, so that the bearing is clamped in the bearing accommodating cavity 3; the inner diameter of the inner ring of the bearing is matched with the outer diameter of a motor shaft 5 of the automobile skylight motor, so that the motor shaft 5 is clamped in the inner ring of the bearing, the adjusting screw 4 is rotatably connected with the motor shaft 5 through the bearing in the bearing accommodating cavity 3, the motor shaft 5 rotating at a high speed and the adjusting screw 4 are prevented from generating severe friction to cause abrasion, and the adjusting screw 4 plays a role in radial and axial limiting on the top end of the motor shaft 5. The external thread 2 of the adjusting screw 4 is matched with the internal thread hole on the gear box 8, the internal thread hole on the gear box 8 is coaxial with the motor shaft 5, the motor shaft 5 is fixedly connected with a worm 6, and the worm 6 is meshed with the worm wheel 7.
