When the glasses motor 185 rotates with electricity, it will drive the gear 185-1 to rotate, and through the cooperation of the gear 185-1 and the curved rack 184, the rotational movement of the glasses motor 185 is converted into the lifting movement of the curved rack 184, thereby The rotation movement of the glasses lifting frame 182 around the smart glasses frame shaft hole 809 on the internal mounting frame 8 is driven, and the lifting movement of the glasses lifting frame 182 is realized, thereby driving the smart glasses 182 and the sun visor 183 on the glasses lifting frame 182. The lifting movement realizes the protection function of the smart glasses 182. A sun visor 183 is installed in front of the smart glasses 182 to block strong light in the environment, thereby enhancing the display effect of the smart glasses 182 and also protecting the smart glasses 182 to a certain extent.

In this embodiment, the upper limit position and the lower limit position of the smart glasses 182 are controlled by the optical switch 187 of the glasses and two limit stops.

The optical switch 187 of the glasses is fixed on the motor fixing base 186 through the switch fixing clip 187-1, that is, it is fixed on the internal mounting frame 8. The upper end of one side of the arc-shaped rack 184 is provided with an upper limit stop piece 184-1, and the lower end is provided with a lower limit stop piece 184-2, and is located on both sides of the optical switch 187 of the glasses.

When the gear 185-1 of the glasses motor 185 moves to the upper limit position on the arc rack 184, the upper limit stop plate 184-1 will cover the glasses photoelectric switch 187, thereby giving an in-position signal to the electronic control circuit in the helmet, thereby achieving The braking of the glasses motor 185 causes the smart glasses 182 to stop at the upper limit position.

When the gear 185-1 of the glasses motor 185 moves to the lower limit position on the arc rack 184, the lower limit stop 184-2 will cover the optical switch 187 of the glasses, thereby giving a signal to the electronic control circuit in the helmet, thereby The glasses motor 185 is braked to stop the smart glasses 182 at the lower limit position.

Of course, the control of the upper limit position and the lower limit position of the smart glasses 182 can also be realized by automatically stopping the glasses motor 185 after each set stroke. The operator of the glasses motor 185 is started by operating the control switch board 6.
