The positioning plate 161 is fixed on the internal mounting frame 8 by screws, that is, fixed on the internal mounting frame 8. Shell structure. The bottom of the positioning plate 161 has two slide grooves 161-2 arranged symmetrically. Both sides of the moving plate 163 are embedded in the sliding groove 161-2, and the moving plate 163 can slide horizontally in the sliding groove 161-2. One side of the positioning plate 161 has a base slot 161-3 penetrating up and down, and the camera mount 164 can move up and down in the base slot 161-3.

The camera motor 162 is fixed below the side of the positioning plate 161 through a shaft hole. The camera motor 162 is an N20 miniature reduction motor and has an output gear 162-1.

The lower part of the moving plate 163 has a rack 163-1. The rack 163-1 is meshed with the output gear 162-1 of the camera motor 162. Below the moving plate 163 are two inclined platens 163-2 arranged symmetrically.

The camera 165 is fixed to the upper end of the camera mount 164. The lower end of the camera mount 164 passes through the base groove 161-3 of the positioning plate 161.

When a positive rotation electric drive signal is given to the camera motor 162, the output gear 162-1 of the camera motor 162 rotates with the clockwise pin and cooperates with the rack 163-1 on the moving plate 163, which drives the moving plate 163 to translate to the right, that is, the moving plate 163 moves in the direction of the camera mount 164. When the moving plate 163 is translated to the right, the inclined plate 164-2 of the camera base 164 will be pressed down by the inclined plate 163-2. The camera base 164 is restrained by the base groove 161-3 on the positioning plate 161. Driven by the moving plate 163, it moves vertically downward. The camera 165 fixed on the camera base 164 moves vertically downward together from the helmet shell 1 The top panoramic camera hole 5 is lowered, and at this time, the return spring 166 is compressed.

When the camera motor 162 receives the reverse electric drive signal, it will move the moving plate 163 to the left through the output gear 162-1 and the rack 163-1, that is, the moving plate 163 moves away from the camera base 164.

The sliding boss 167-2 fits into the inclined guide 168-1, and the positions and shapes of the two match. A rubber sheet 167-3 is fixed to the upper end of the shielding cover 167.

The shielding cover 167 is disposed between the left rail piece 168a and the right rail piece 168b, and the embedded boss 167-1 is inserted into the U-shaped groove 161-4 of the moving plate 163.

When the moving plate 163 moves to the right, that is, when the camera 165 descends, the U-shaped groove 161-4 of the moving plate 163 drives the shielding cover 167 to move to the right in the same direction, and the shielding cover 167 moves obliquely upward along the inclined guide 168-1. When the camera 165 descends to exit the panoramic camera hole 5, the blocking cover 167 just blocks the panoramic camera hole 5 with the rubber sheet 167-3. When the camera hole of the helmet is completely blocked, the camera motor 162 stops rotating, and the camera 165 reaches the lower limit position, thereby achieving the descending protection function of the camera 165 and having a certain waterproof effect.

When the moving plate 163 moves to the left, the camera 165 is rising. The U-shaped groove 161-4 of the moving plate 163 drives the shielding cover 167 to move to the left in the same direction, and the shielding cover 167 moves obliquely downward along the inclined guide 168-1 at the same time. When the rubber sheet 167-3 leaves the panoramic camera hole 5, the camera 165 just rises to the bottom of the panoramic camera hole 5. After rising for a period of time, the camera 165 will reach the working position, that is, the upper limit position, and the camera motor 162 stops rotating, thereby The ascent function of the camera 165 is realized.

In this embodiment, the upper limit position and the lower limit position of the camera 165 are controlled by the camera photoelectric switch 169 and the two positioning stops.

An upper positioning block 163-3 and a lower positioning block 163-4 are disposed below the moving plate 163, and are located on both sides of the camera photoelectric switch 169. In this embodiment, the upper positioning block 163-3 is on the left side of the lower positioning block 163-4.

When the camera motor 162 drives the moving plate 163 to the right, when it moves to the right extreme position, the lower positioning block 163-4 will block the camera photoelectric switch 169, thereby giving the electronic control circuit in the helmet a signal in place to achieve the camera The motor 162 is braked to stop the camera 165 at the lower limit position.

When the camera motor 162 drives the moving plate 163 to move to the left, when it moves to the left extreme position, the upper positioning block 163-3 will block the camera photoelectric switch 169, thereby giving the electronic control circuit in the helmet a signal in place to achieve the camera The motor 162 is braked, and the camera 165 is stopped at the upper limit position.

The left and right extreme positions of the moving plate 163 are also the upper and lower extreme positions of the camera 165.

Of course, the control of the upper limit position and the lower limit position of the camera 165 can also be realized by automatically stopping the camera motor 162 after each set stroke. The camera motor 162 is started by an operator by operating the control switch board 6.

Guide grooves or guide rails can be provided on both sides of the arc-shaped rack 184 to restrict the movement direction of the arc-shaped rack 184, so that the movement of the arc-shaped rack 184 is more stable.

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 thus achieves a protection function for 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, 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.
