Meanwhile, the device is suitable for different users, namely, adjusting equipment is arranged to enable the heads of different users to be attached to the helmet 100 better. For convenience of description, the actual front-back, left-right, up-down direction of the eyes of the user after the device is worn on the head is taken as the front-back, left-right, up-down direction of the device during the description. The specific structure is as follows:

referring to fig. 1 to 3, a shell 110 of a helmet 100 of the device is rectangular, a receiving cavity 120 for receiving a head is formed in the shell, the receiving cavity 120 is hemispherical to adapt to the shape of the head, a head display 200 is positioned at the front end of the helmet 100, and is slidably connected with the shell 110 along the horizontal direction, as can be seen from fig. 1, a right angle sliding member 220 is arranged above the head display 200, referring to fig. 3, and the horizontal end of the sliding member 220 is slidably connected with the shell 110 in the specific manner that: the casing 110 is provided with a first protruding block 111 above, the first protruding block 111 is located in the chute of the sliding piece 220, a through hole is formed in the first protruding block 111, a guide post is arranged in the chute of the sliding piece 220, the guide post penetrates through the through hole, sliding fit between the first protruding block 111 and the sliding piece 220 is achieved, a spring penetrates through the slide post, and two ends of the spring are respectively abutted against or fixedly connected with the inner walls of the first protruding block 111 and the chute.

This achieves the effect that the head display 200 can slide with respect to the helmet 100, and when the external force driving the head display 200 to approach the helmet 100 is removed, the head display 200 is restored to the original position by the elastic force of the spring. Therefore, in order to achieve the effect that the head display 200 is always clung to eyes during the use of the user, the mechanical structure of the device for providing external force is as follows:

referring to fig. 1, the helmet 100 is provided with a first transmission assembly including a first threaded rod 310, a moving frame 320 and a push part 330. The first threaded rod 310 is rotatably connected with the helmet 100, and as can be seen from fig. 1, the moving frame 320 is provided at both left and right sides of the helmet 100, i.e., at the sides of the human ear, and finally is converged at the chin of the user, and the pushing part 330 is fixedly connected with the connecting frame and extends forward, and then extends to the right angle below the head display 200.

A moving block 210 is arranged below the head display 200, the moving block 210 is provided with an inclined surface 211, the inclined surface 211 comprises a first end and a second end, the second end is positioned below the first end, and the inclined surface 211 is inclined towards a direction close to the shell 110 along the direction from the first end to the second end;

the first threaded rod 310 is located above the shell 110 and is rotatably connected with the first threaded rod 310 to output power, the moving frame 320 is in threaded connection with the first threaded rod 310, the pushing part 330 is fixedly connected with the moving frame 320 and is located right below the inclined plane 211, and when the first threaded rod 310 rotates, the moving frame 320 and the pushing part 330 can be driven to move up and down relative to the helmet 100 so as to prop against or separate from the inclined plane 211. Therefore, after the user wears the helmet 100, the user can rotate the threaded rod by hand, so that the movable frame 320 moves upwards, the pushing part 330 abuts against the inclined surface 211 and then moves upwards, the movable block 210 moves towards the helmet 100, so that the head display 200 is driven to move towards the human eyes until the head display is close to the human eyes, the user can determine the close degree according to the preference of the user, and the threaded connection is reliable and simple, so that the head display 200 cannot be separated from the human eyes in the use process, and the use feeling of the user is ensured. When the user needs to take off the helmet 100 after using, the user only needs to reverse the first threaded rod 310 to move the pushing part 330 downwards, and the head display 200 can be reset by the elasticity of the spring.

In the above embodiments, both the first threaded rod 310 and the spring are preferred devices in the present device, in other embodiments, the first threaded rod 310 may be replaced with a more advanced member, such as an electronic part, and the spring may be replaced with another elastic member 221, such as a spring pin piece, etc., by moving the electronic operation moving frame 320 up and down.

Referring to fig. 1 and 2, a first supporting portion 113 is fixedly connected to the vertical end of the sliding member 220 in a horizontal manner, and the connecting rod 230 passes through the housing 110, that is, the first supporting portion 113 is located in the accommodating cavity 120, when the head display 200 reciprocates relative to the helmet 100, the first supporting portion 113 also moves synchronously, and it is conceivable that when the head display 200 is closely attached to a human eye, the first supporting portion 113 is also closely attached to the forehead of the user.

Preferably, the first supporting portion 113 is in a soft circular arc shape, so as to better fit the forehead of the user.

The soft pad 321 is also provided at the position of the moving frame 320 at the chin of the user, and similarly, when the head display 200 is closely attached to the human eye, it indicates that the moving frame 320 has moved upward by a distance, and the soft pad 321 is closely attached to the chin of the user.

Referring to fig. 2, a cushion 321 is also provided above the receiving cavity 120 of the helmet 100 to ensure a user's feeling.

Preferably, the moving frame 320 is further provided with a second threaded rod 322, the second threaded rod 322 penetrates through the moving frame 320 and is in threaded connection with the moving frame, and the upper end of the second threaded rod 322 is fixedly connected with the soft cushion 321, so that the soft cushion 321 can achieve secondary adjustment of the distance between the soft cushion 321 and the chin of a user, and the user can obtain better use feeling.

At the rear of the helmet 100, a second adjustable abutment 114 is also provided, specifically configured as follows:

referring to fig. 1, the device further includes a second transmission assembly, the second transmission assembly includes a gear pair and a transmission portion, the transmission portion and the helmet 100 can move relatively along the front-rear direction, and the transmission portion passes through the rear wall of the helmet 100 and is fixedly connected with the first supporting portion 113.

Specifically, the transmission part is composed of a transmission shaft 340 and a connection plate 350 in fig. 1, the transmission shaft 340 is in threaded connection with the connection plate 350, a second protruding block 112 is arranged above the helmet 100, a through hole is also arranged on the second protruding block 112, and the transmission shaft 340 penetrates through the second protruding block 112 to be in rotational connection with the second protruding block, so that when the transmission shaft 340 rotates, the transmission shaft 340 cannot displace relative to the helmet 100, but the connection plate 350 approaches or moves away from the helmet 100.

The connection plate 350 is right-angled, referring to fig. 2, and the other end passes through the shell 110 of the helmet 100 and enters the accommodating cavity 120 to be fixedly connected with the second abutting portion 114. The connection of the end of the drive shaft 340 facing away from the connection plate 350 to the first threaded rod 310 can be seen in fig. 2: the gear pair comprises a first gear 361 and a second gear 362, and the first gear 361 and the second gear 362 are in right-angle transmission engagement; the first gear 361 is fixedly connected with the first threaded rod 310, and the second gear 362 is fixedly connected with the other end of the transmission part.

Therefore, when the user rotates the first threaded rod 310, the first abutting portion 113, the second abutting portion 114 and the cushion 321 on the moving frame 320 will move toward the head until they are tightly attached to the forehead, the hindbrain and the chin of the user. The user can also rotate the second threaded rod 322 to secondarily adjust the tight contact degree of the soft cushion 321 on the moving frame 320 with the chin thereof.

In one embodiment, the outer wall of the helmet 100 is further provided with a signal receiver 400 and a signal lamp, both of which are in communication connection with the head display 200 to display signal connection conditions, and the electronic communication connection relationship of the head display 200 itself is relatively perfect in the prior art, so specific relationships thereof are not repeated herein, and specific electronic devices can be added to the helmet 100 according to the requirements of users and manufacturers to realize more functions.
