Figure 1 and Figure 4 The outer toothed ring 2 is fixedly connected to a wiper blade 41, which is arranged along the diameter of the outer toothed ring 2. The wiper blade 41 is fixedly connected to a wiper silicone strip 42, which is attached to the outer side of the lens 12 on the side away from the wiper blade 41. Multiple water-permeable holes 22 are arranged in a circular array on the outer side of the lens barrel 11, and the water-permeable holes 22 are located near the end face of the wiper blade 41.

[0016] Specifically, by setting up a drive motor 31 and a drive gear 32, the external gear ring 2 is driven to rotate, which in turn drives the wiper blade 41 and the wiper silicone strip 42 to rotate. The wiper silicone strip 42 wipes away water droplets on the lens 12. Multiple water-permeable holes 22 are arranged in a circular array on the outer side of the lens barrel 11. The water droplets wiped off by the wiper silicone strip 42 are discharged through the water-permeable holes 22.
