The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of this disclosure. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0028] To better understand the technical solutions and beneficial effects of this disclosure, the following detailed description is provided in conjunction with specific embodiments:

[0029] like Figures 1 to 4 As shown, this is a rotating bias-tolerant structure 10 according to an embodiment of the present disclosure, including a housing assembly 100, a rotating lamp body assembly 200, a bias-correcting shaft assembly 300, and a drive assembly 400. The housing assembly 100 includes a top cover 110, a cylindrical body 120, and a face ring 130 connected in sequence. The rotating lamp body assembly 200 is installed inside the cylindrical body 120 and is also rotatably connected to the face ring. The rotating lamp body assembly 200 is rotatably disposed on the face ring 130, and a lamp body for emitting a light source is provided on the rotating lamp body assembly 200.

[0030] Further, the deviation-allowing rotating structure 10 comprises a first shaft sleeve 310, a buffer block 320, a second shaft sleeve 330 and a shaft core column 340. The first shaft sleeve 310 is fixed to the top cover 110. The first shaft sleeve 310 is provided with a first protruding block 311. The second shaft sleeve 330 is provided with a second protruding block 331. The first protruding block 311 and the second protruding block 331 are correspondingly engaged and form a gap 301. The buffer block 320 is provided with a buffer blade 321. The buffer blade 321 is arranged in the gap 301. The shaft core column 340 is connected to one end of the second shaft sleeve 330 away from the second protruding block 331. The shaft core column 340 is arranged in the rotating hole 201. The driving assembly 400 is fixedly arranged in the rotating lamp body assembly 200. The output end of the driving assembly 400 is engaged with the shaft core column 340 through a gear. The driving assembly 400 is used to drive the rotating lamp body assembly to rotate on the surface ring 130.

[0031] In the embodiment, when the driving assembly 400 is started, the output end gear of the driving assembly 400 is engaged with the shaft core column 340. The driving assembly 400 drives the rotating lamp body assembly 200 to rotate on the surface ring 130 along the shaft core column 340. During the rotation, there is a tolerance between the driving assembly 400 on the rotating lamp body assembly 200 and the shaft core column 340. The rotating lamp body assembly 200 and the driving assembly 400 rotate eccentrically along the shaft core column 340. Thus, the force acting on the second shaft sleeve 330 connected to the shaft core column 340 changes. The buffer block 320 can buffer the vibration and impact between the first shaft sleeve 310 and the second shaft sleeve 330. Thus, the shaft core column 340 can adapt to the deviation of the engagement with the driving assembly 400.

[0032] The buffer blade 321 of the buffer block 320 is arranged in the gap 301 between the first shaft sleeve 310 and the second shaft sleeve 330. Thus, the buffer block 320 buffers the vibration and impact between the first shaft sleeve 310 and the second shaft sleeve 330. The dynamic stress between the first shaft sleeve 310 and the second shaft sleeve 330 is reduced. The shaft core column 340 connected to the second shaft sleeve 330 can adapt to the deviation caused by the rotation of the driving assembly 400 and the rotating lamp body assembly 200 on the surface ring 130. The vibration and impact acting on the driving assembly 400 and the shaft core column 340 are reduced. Thus, the durability of the deviation-allowing rotating structure 10 is improved. The movement of the rotating lamp body assembly 200 is more stable. The vibration and noise are reduced.

In this embodiment, the fixing piece 370 can fix the rotating disc 360, the limiting part 351 and the second shaft sleeve 330 as a whole, so that the contact between the first shaft sleeve 310, the buffer block 320 and the second shaft sleeve 330 is stable, and the abrasion caused by the loosening between the rotating disc 360, the limiting part 351 and the second shaft sleeve 330 is avoided.

[0036] As shown in the drawings, Figure 1 As shown in the drawings, in one of the embodiments, the inner hole radius of the buffer block 320 is smaller than the radius of the first shaft sleeve 310 and the second shaft sleeve 330. In this embodiment, the limiting part 351 is offset and contacts the inner wall of the buffer block 320, the inner wall of the buffer block 320 can buffer the impact and vibration of the limiting part 351, thereby reducing the contact between the limiting part 351 and the first shaft sleeve 310 and the second shaft sleeve 330, and further improving the service life of the first shaft sleeve 310 and the second shaft sleeve 330.
