[0021] Please see Figures 1-7 To provide reliable locking and ventilation control for the helmet and visor, the technical solution provided in this embodiment includes a helmet shell 1, with visors 2 hinged forward from both sides of the helmet shell 1. The helmet shell 1 has a mounting base 3 at the chin, and the mounting base 3 has ventilation holes 4. An integrated panel 5 is detachably mounted on the outside of the helmet shell 1, fastened to the mounting base 3. An elastic locking hook 6 is provided upward on the integrated panel 5. The visor 2 has a groove 7 adapted to the elastic locking hook 6. The visor 2 also has a paddle 8 extending away from the helmet shell 1. The integrated panel 5 has a hollow structure 9 at the position corresponding to the ventilation holes 4. An on / off switch 10 is vertically slidable between the center of the integrated panel 5 and the mounting base 3. The on / off switch 10 is integrally connected to a baffle 11. The baffle 11 can open and close the connection between the hollow structure 9 and the ventilation holes 4 along the sliding path of the on / off switch 10. During installation, the elastic locking hook 6 engages with the groove 7 to form a fixed lock, while the integrated panel 5 snaps into the mounting base 3 to achieve modular disassembly; the on / off switch 10 slides through the baffle 11 to adjust the connection between the hollow structure 9 and the ventilation hole 4; after the lens 2 engages with the elastic locking hook 6 through the groove 7, it can be unlocked by pulling with one hand using the lever 8, and the baffle 11 moves with the on / off switch 10 to switch the ventilation on / off; this simplifies the maintenance process, improves the reliability of locking and the convenience of ventilation adjustment, and enhances the overall efficiency of use.

[0022] To enhance the fixation and prevent detachment of the elastic locking hook 6, the technical solution provided in this embodiment includes locking grooves 12 provided between the two sides of the elastic locking hook 6 and the integrated panel 5. The locking grooves 12 provide elastic deformation space when the locking hook engages; when the elastic locking hook 6 is engaged in the groove 7, the locking grooves 12 allow slight bending to accommodate the engagement; this improves the deformation capability and vibration resistance of the locking hook, reducing the risk of accidental unlocking.

[0023] To achieve multi-level adjustment of ventilation opening and closing, the technical solution provided in this embodiment includes an adjustment mechanism comprising an adjustment column 13 fixedly mounted on the on / off switch 10, and an integrated panel 5 having at least two adjustment holes 14 adapted to the adjustment column 13. The adjustment holes 14 are linearly distributed along the sliding path of the on / off switch 10, and the sides of the multiple adjustment holes 14 are interconnected. An arc-shaped limiting surface 15 is provided between adjacent adjustment holes 14. The adjustment column 13 is inserted into different adjustment holes 14 to achieve level switching; when the on / off switch 10 slides, the adjustment column 13 slides from one adjustment hole 14 to another, and the arc-shaped limiting surface 15 guides the path and provides a stop; providing multi-point ventilation control, enhancing operational convenience and adjustment accuracy.

[0024] To accommodate component deformation at different settings, the technical solution provided in this embodiment includes an integrated panel 5 having multiple interconnected arc-shaped expansion and contraction holes 16 with varying curvatures around the periphery of the multiple adjustment holes 14. The arc-shaped expansion and contraction holes 16 allow the integrated panel 5 material to expand and contract with varying temperatures; when the adjustment column 13 switches between adjustment holes 14, the arc-shaped limiting surface 15 can be provided with deformation margin by the arc-shaped expansion and contraction holes 16.

[0025] To ensure the sliding limit and smooth operation of the on / off switch 10, the technical solution provided in this embodiment includes a vertically arranged slide groove 27 on the on / off switch 10, and a first locking block 17 extending from the integrated panel 5 towards the on / off switch 10. The height of the first locking block 17 is less than the length of the slide groove 27, and the first locking block 17 is engaged with the inner side of the slide groove 27. The first locking block 17 cooperates with the slide groove 27 to limit the range of movement; when the on / off switch 10 slides, the slide groove 27 is constrained in the vertical direction by the first locking block 17 to prevent dislocation.

[0026] To optimize the external protection and ease of operation of the integrated panel 5, the technical solution provided in this embodiment includes an outer panel 18 on the side of the integrated panel 5 away from the helmet shell 1. The outer panel 18 has an elongated hole 19 that partially exposes the on / off switch 10. The elongated hole 19 allows the on / off switch 10 to be operated manually. The outer panel 18 covers the integrated panel 5, and the on / off switch 10 is exposed through the elongated hole 19, which facilitates finger sliding, enhances protection and human-machine interaction, and simplifies ventilation adjustment.

[0027] To provide a detachable connection between the integrated panel 5 and the helmet shell 1, the technical solution provided in this embodiment includes a connecting pin 20 and a second locking block 21 extending from the outer panel 18 to one side of the helmet shell 1. A connecting hole 22 is provided on the helmet shell 1. The connecting pin 20 passes through the integrated panel 5 and is press-fitted into the connecting hole 22. A connecting piece 23 adapted to the second locking block 21 is provided on the integrated panel 5. The connecting pin 20 is inserted into the connecting hole 22 to form an interference fit, and the second locking block 21 is engaged with the connecting piece 23. During assembly, the connecting pin 20 is pressed into the connecting hole 22 to tighten the connection, and the second locking block 21 engages and locks the connection. This enables quick disassembly and maintenance and improves connection stability.

[0028] To enhance the adaptability of the interference fit of the connecting pin 20, the technical solution provided in this embodiment includes a radially formed expansion groove 24 at the end of the connecting pin 20 near the helmet shell 1. The expansion groove 24 provides radial deformation space when the connecting pin 20 is inserted; the expansion groove 24 contracts or expands under pressure to adapt to the size of the connecting hole 22.

[0029] To enhance the fixing effect and prevent the connecting pin 20 from coming loose, the technical solution provided in this embodiment includes a flange 25 provided circumferentially in the middle section of the expansion and contraction groove 24 of the connecting pin 20, the width of which does not exceed the diameter of the connecting pin 20. The flange 25 expands radially during connection to provide a stop; the flange 25 locks the edge of the connecting hole 22 in the middle section of the expansion and contraction groove 24; preventing the connection from loosening and improving the overall connection strength.

[0030] To optimize the operating space and user experience of the paddle 8, the technical solution provided in this embodiment includes a recessed area 26 on the outer panel 18 at the position of the paddle 8. The recessed area 26 avoids interference with the paddle 8; the finger can easily reach the recessed area 26 when the paddle 8 is unlocked.

[0031] The working principle of this utility model is as follows: When the lens 2 is installed and closed, the user rotates the lens 2 towards the helmet shell 1 to close it. The elastic locking hook 6 on the integrated panel 5 automatically engages with the groove 7 of the lens 2 to form a lock. At the same time, the locking groove 12 provides elastic deformation margin to ensure a stable engagement. When unlocking, the user uses their finger to push the lever 8 of the lens 2 to apply a reverse force to disengage the elastic locking hook 6 from the groove 7, achieving quick separation with one hand. In terms of ventilation control, the user slides the on / off switch 10 to drive the integrated baffle 11 to move vertically, switching the connection state between the hollow structure 9 and the ventilation hole 4. When open, external airflow enters the helmet through the hollow structure 9 and the ventilation hole 4. When closed, the baffle 11 completely blocks the airflow. During disassembly and maintenance, the user can remove the integrated panel 5 from the outside. The interference fit design of its connecting pin 20 and flange 25 allows for quick separation, facilitating cleaning or replacement of parts.

[0032] The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
