Referring to fig. 1, an embodiment of the present invention provides an angle adjusting mechanism including a mounting member 1, a first adjusting assembly 2, and a second adjusting assembly 3. Wherein the first and second adjustment assemblies 2, 3 may be arranged between the mounting member 1 and the other member such that the first and second adjustment assemblies 2, 3 may cooperate to adjust the angle between the mounting member 1 and the other member.

When the device is specifically arranged, the mounting piece 1 is provided with the first adjusting component 2 and the second adjusting component 3 which are parallel, a first connecting line 23 is arranged between the first adjusting component 2 and the axis of the mounting piece 1, a second connecting line 33 is arranged between the second adjusting component 3 and the axis of the mounting piece 1, and the first connecting line 23 is perpendicular to the second connecting line 33.

Specifically, the first adjustment assembly 2 has axially opposite first and second ends 24, 25, and the second adjustment assembly 3 has axially opposite first and second ends 34, 35. The first end 24 of the first adjustment assembly 2 and the first end 34 of the second adjustment assembly 3 are both connected to the same side of the mounting 1, and the axis of the first adjustment assembly 2 and the axis of the second adjustment assembly 3 are parallel. The first and second adjustment assemblies 2, 3 are of uniform length so that the other component is connected to the second end 25 of the first adjustment assembly 2 and the second end 35 of the second adjustment assembly 3.

A first connecting line 23 is arranged between the axis of the first adjusting component 2 and the axis of the mounting piece 1, a second connecting line 33 is arranged between the axis of the second adjusting component 3 and the axis of the mounting piece 1, and the first connecting line 23 is perpendicular to the second connecting line 33, so that the adjusting direction of the first adjusting component 2 can be perpendicular to the adjusting direction of the second adjusting component 3.

Further, the length of the first connection line 23 coincides with the length of the second connection line 33. So that the distance between the first adjusting component 2 and the axis of the mounting piece 1 is consistent with the distance between the second adjusting component 3 and the axis of the mounting piece 1, and the first adjusting component 2 and the second adjusting component 3 are matched conveniently to adjust the angle between the mounting piece 1 and the other component.

The first adjusting assembly 2 comprises a first telescopic member 21 and at least two first universal joints 22, the two first universal joints 22 being arranged on the two axial ends of the first telescopic member 21, respectively, the first telescopic member 21 being rotatably connected with the mounting member 1 by means of the first universal joints 22. When the first telescopic member 21 is rotatably connected to the other member through the other first universal joint 22, the first telescopic member 21 can be telescopic to rotate the first universal joint 22, so that the angle between the mounting member 1 and the other member can be adjusted.

The second adjusting assembly 3 comprises a second telescopic member 31 and at least two second universal joints 32, the two second universal joints 32 are respectively arranged at two axial ends of the second telescopic member 31, and the second telescopic member 31 is rotatably connected with the mounting member 1 through the second universal joints 32. When the second telescopic member 31 is rotatably connected to the other member through the other second universal joint 32, the second telescopic member 31 can be operated to rotate the second universal joint 22, so that the angle between the mounting member 1 and the other member can be adjusted.

Specifically, one of the first and second universal joints 22 and 32 is connected to the mount 1, and the other of the first and second universal joints 22 and 32 is used to connect to the other component. Since the first universal joint 22 and the second universal joint 32 have multiple angle adjusting directions, and the first connecting line 23 is perpendicular to the second connecting line 33, at least two angle adjusting directions can be provided between the mounting member 1 and the other member, and the two angle adjusting directions are perpendicular.

The first and second universal joints 22 and 32 are each universal ball joints. Since the universal ball joint has various angle adjusting directions, the universal ball joint can be matched with different telescopic operation amounts of the first telescopic piece 21 and the second telescopic piece 31, so that the angle between the mounting piece 1 and the other part can have more adjusting directions.

The first telescopic member 21 and the second telescopic member 31 are all electric push-pull members, the telescopic operation of the first telescopic member 21 and the second telescopic member 31 is more conveniently controlled in an electric mode, so that the irradiation angle swing of the lamp is realized, and in the application, the electric push-pull members are electric push rods. The limit switch is arranged in the electric push rod, so that the electric push rod can automatically cut off the power supply after being stretched to two ends.

The angle adjusting mechanism of the application can enable the mounting piece 1 to be connected with another component through the first adjusting component 2 and the second adjusting component 3, so that the angle between the mounting piece 1 and the another component can be adjusted through the first universal joint 22 and the second universal joint 32, and meanwhile, the adjusting quantity of the angle can be controlled through the expansion and contraction of the first telescopic piece 21 and the second telescopic piece 31. In addition, since the first universal joint 22 and the second universal joint 32 are universal ball joints, and the first connecting line 23 is perpendicular to the second connecting line 33, the angle between the mounting member 1 and the other member has various adjustment directions. That is, when the user individually drives the first telescopic member 21 to be telescopic, the mount member 1 can be rotated in the first direction with respect to the other member; when a user independently drives the second telescopic member 31 to telescopic, the mounting member 1 can rotate relative to the other part along the second direction; when the user drives the first telescopic member 21 and the second telescopic member 31 to extend and retract simultaneously, the mounting member 1 can rotate in different directions relative to the other component by controlling the extension and retraction amounts of the first telescopic member 21 and the second telescopic member 31.

By connecting the first rotating member 4 and the second rotating member 5 to the mount 1 and the other member, respectively, the connection stability between the mount 1 and the other member can be enhanced. In addition, because the second rotating member 5 is rotationally connected with the first rotating member 4, the first rotating member 4 and the second rotating member 5 can not influence the rotating effect between the mounting member 1 and the other component, and further, the first adjusting component 2 and the second adjusting component 3 can not influence the angle adjustment of the mounting member 1 and the other component.

The second telescopic member 31 is rotatably connected with the mounting member 1 through one of the second universal joints 32, and the second telescopic member 31 is rotatably connected with the lamp housing 8 through the other of the second universal joints 32, so that the second telescopic member 31 can be operated in a telescopic manner, and the angle between the mounting member 1 and the lamp housing 8 can be adjusted.
