[0021] As shown in Figs. 1-2 The application embodiment provides a vehicle lamp lens transmission structure with a reduction ratio motor, which comprises a base 1.

[0022] A lens assembly 2 is rotatably installed on the base 1.

[0025] Through the arrangement of the reduction motor 3, when the reduction motor 3 adjusts the lens assembly 2, the resonance of the reduction motor 3 and the base 1 is reduced, thereby effectively reducing the noise.

[0026] In one embodiment, the transmission assembly comprises a transmission rod 4, a first transmission wheel 31, a second transmission wheel 5, a third transmission wheel 6 and a fourth transmission wheel 7. The transmission rod 4 is rotatably installed at both ends of one side of the base 1. The first transmission wheel 31 is arranged at the output end of the reduction motor 3. The second transmission wheel 5 and the third transmission wheel 6 are fixedly sleeved on the outer wall of the transmission rod 4 at intervals. The fourth transmission wheel 7 is fixedly sleeved on one end of the lens assembly 2 close to the transmission rod 4. The first transmission wheel 31 is in transmission connection with the second transmission wheel 5. The third transmission wheel 6 and the fourth transmission wheel 7 are in transmission connection. The reduction ratios between the first transmission wheel 31, the second transmission wheel 5, the third transmission wheel 6 and the fourth transmission wheel 7 are consistent.

[0030] Through the consistent setting of the speed reduction ratio between the first transmission wheel 31, the second transmission wheel 5, the third transmission wheel 6 and the fourth transmission wheel 7, the speed reduction motor 3 is used to replace the large speed reduction ratio between the original worm gears, the speed reduction ratio requirement of the worm gears is reduced, thereby the structural space occupied by the worm gears under the large speed reduction ratio is reduced, and the volume of the transmission assembly is effectively reduced.

[0031] In an embodiment, a first bearing 21 is sleeved at the connection between the lens assembly 2 and the base 1, and the outer wall of the first bearing 21 is fixedly connected with the base 1.
