[0044] Embodiment

[0045] Please refer to Figure 1-10 As shown, this embodiment provides a helmet goggle opening and closing structure, including a helmet body 1, a lens 2, a lens connecting seat 3, and a cover plate 4. The lens connecting seats 3 are fixed on both sides of the helmet body 1, and a limiting channel 31 is provided on the lens connecting seats 3; both ends of the lens 2 are bent relatively, and an installation channel 21 is provided. Both ends of the lens 2 are attached to the lens connecting seats 3. Connecting handles 134 protruding outward are provided on both sides of the helmet body 1. The connecting handles 134 pass through the limiting channels 31 and extend into the installation channels 21. A clamping member is provided in the limiting channels 31; a hooking member protruding outward is provided at the channel opening of the installation channel 21, and the hooking member extends into the limiting channels 31. The hooking member and the clamping member are in abutting contact or separated from each other. The cover plate 4 is covered on the outer sides of both ends of the lens 2, and a connecting portion extending outward is provided on the cover plate 4. The connecting portion is detachably connected to the connecting handle 134.

[0046] The lens 2 is rotatably disposed on the helmet body 1 through the lens connecting seat 3. The cover body is covered on the position where the lens 2 is connected to the lens connecting seat 3 to limit the lens 2 to ensure that the lens 2 will not fall off during the rotation process. When the lens 2 is in the closed state, the hooking member and the clamping member are in abutting contact with each other; when the lens 2 is in the open state, the hooking member rotates with the lens 2, so that the hooking member and the clamping member are separated from each other. The lens 2 can be quickly removed by disassembling the cover plate 4. The assembly is the same, achieving quick disassembly and assembly and improving the efficiency of accessory replacement.

[0047] In this embodiment, the diameter of the limit channel 31 is larger than that of the installation channel 21. The engaging member includes an engaging plate 311, which is fixed to one side opening of the limit channel 31 facing the installation channel 21 on the same side. The engaging plate 311 and the inner side wall of the limit channel 31 form a hook-shaped engaging structure to limit the engaging component. The engaging component includes a bent plate 211, which is fixed to one side opening of the installation channel 21 facing the limit channel 31 on the same side. The bent plate 211 extends to the inside of the engaging plate 311 and bends towards the engaging plate 311. The bent plate 211 forms an "L"-shaped bent plate 211, and the free end of the bent plate 211 abuts against or separates from the inner side surface of the engaging plate 311. In this embodiment, the engaging plate 311 is an arc-shaped plate, the engaging plate 311 is concentric with the connecting handle 134, the radian of the engaging plate 311 is less than 360°, and there is a space between the inner ring surface of the engaging plate 311 and the connecting handle 134. A smaller plywood is set to reduce the material consumption and cost while ensuring the limiting effect on the bent plate 211.

[0048] Please refer to Figure 3 、 5 and Figure 9 As shown, further, a limit block 312 is fixed in the limit channel 31, and the limit block 312 is connected to one side of the engaging plate 311. The limit block 312 blocks one end opening of the engaging plate 311 to limit the bent plate 211 entering the area of the engaging plate 311, avoiding too long a movement path of the bent plate 211 and affecting the contact limiting effect between the engaging plate 311 and the bent plate 211. In this embodiment, the number of both the engaging plate 311 and the limit block 312 is two, and the engaging plate 311 and the limit block 312 are symmetrically distributed along the center of the circle of the connecting handle 134. Further, the number of the bent plates 211 is also two, and the two bent plates 211 correspond to the two engaging plates 311 one by one, effectively improving the limiting effect of the engaging plate 311 on the lens 2. Similarly, three or more engaging plates 311, limit blocks 312 and bent plates 211 can also be set according to requirements.

[0049] In this embodiment, an activity channel 32 is provided on the lens connecting base 3. On the inner sides of both ends of the lens 2, there are provided activity blocks 22 extending outward. The activity blocks 22 extend into the activity channel 32. The activity blocks 22 perform reciprocating motion within the activity channel 32, and the activity channel 32 limits the position of the activity blocks 22, thereby restricting the rotation position of the lens 2 to prevent the lens 2 from rotating too much and affecting the wearing effect. Further, positioning protrusions 321 are provided at both ends of the inner side surface of the activity channel 32. The side surfaces of the positioning protrusions 321 are the same as the side surface shapes of the activity blocks 22. In this embodiment, the activity blocks 22 are cylindrical activity blocks 22, and the side surfaces of the positioning protrusions 321 are arc-shaped curved surfaces 241. The positioning protrusions 321 between the inner side surfaces correspond one by one, and the ratio between the distance between the corresponding positioning protrusions 321 and the diameter of the activity blocks 22 is 4:5 - 6:7. In this embodiment, the ratio between the distance between the corresponding positioning protrusions 321 and the diameter of the activity blocks 22 is 5:6. Similarly, the ratio between the distance between the corresponding positioning protrusions 321 and the diameter of the activity blocks 22 can also be 4:5 or 6:7. The distance between the corresponding positioning protrusions 321 is slightly smaller than the diameter of the activity blocks 22. The activity blocks 22 pass through the positioning protrusions 321 by virtue of their own softness, and the positioning protrusions 321 limit the activity blocks 22 to ensure that the lens 2 can remain stable when in the closed state or when opened to the maximum state, preventing the lens 2 from rotating during driving and affecting driving safety. By adjusting the ratio between the distance between the corresponding positioning protrusions 321 and the diameter of the activity blocks 22 due to factors such as the self-weight of the lens 2, the limiting force of the positioning protrusions 321 on the activity blocks 22 is adjusted to ensure that the positioning protrusions 321 have a good limiting effect on the activity blocks 22.

[0050] Please refer to Figure 3 、 4 and Figure 7 As shown, further, fourth positioning channels 23 are provided at both ends of the lens 2, and a third positioning block 33 is provided on the lens connecting base 3. The third positioning block 33 is embedded in the fourth positioning channel 23. The third positioning block 33 is located at the starting end of the fourth positioning channel 23, that is, when the lens 2 is in the closed state, it is located at the front end of the fourth positioning channel 23; in the rotating state of the lens 2, the space at the rear end of the fourth positioning channel 23 provides a movement space for the third positioning block 33. The third positioning block 33 and the activity blocks 22 jointly position the end positions of the lens 2 to ensure that the installation channel 21 at the end of the lens 2 and the connecting handle 134 are concentric, thereby ensuring stable rotation of the lens 2.

[0051] Please refer to Figure 3 and Figure 6As shown in the figure, the helmet body 1 includes a lower perimeter plate 13, a body connection seat 12, and an upper perimeter plate 11. The two ends of the upper perimeter plate 11 are bent relatively, and the body connection seats 12 are arranged at the two ends of the upper perimeter plate 11. The two ends of the lower perimeter plate 13 are bent relatively and are fitted and arranged on the body connection seats 12. Connection handles 134 are arranged on the outer sides of the two ends of the lower perimeter plate 13. A connection channel 1341 is opened in the connection handle 134, and a connecting rod 5 is arranged in the connection channel 1341. The connecting rod 5 passes through the body connection seat 12 and is fixedly connected to the upper perimeter plate 11. The connection part of the cover plate 4 is detachably connected to the connecting rod 5. Further, the connection part is an insertion plate 41. A plug-in notch is arranged at the end of the connecting rod 5. The plug-in notch and the inner side wall of the connection channel 1341 enclose a plug-in position. The insertion plate 41 is inserted into the plug-in notch. The connection structure is simple and reliable. While ensuring a good limiting effect on the lens 2, the disassembly and assembly difficulty of the cover plate 4 is reduced. In this embodiment, the connecting rod 5 is a threaded rod, and the connecting rod 5 passes through the connection channel 1341 and is threadedly connected to the upper perimeter plate 11. In this embodiment, the lower perimeter plate 13 corresponds to the position of the helmet chin, and the upper perimeter plate 11 corresponds to the position of the helmet forehead. The lower perimeter plate 13 and the upper perimeter plate 11 are connected to each other through the body connection seat 12. The connection structure is simple and convenient for disassembly and assembly.

[0052] In this embodiment, first positioning channels 132 are opened at the two ends of the lower perimeter plate 13, and second positioning channels 34 are opened on the lens connection seat 3. The positions of the first positioning channels 132 and the second positioning channels 34 correspond to each other. An outwardly protruding first positioning block 121 is arranged on the body connection seat 12. The first positioning block 121 passes through the first positioning channel 132 and extends into the second positioning channel 34. In this embodiment, the number of the first positioning blocks 121 is two, and the sides of the two first positioning blocks 121 are in mutual abutting contact with the inner side walls of the first positioning channel 132 and the second positioning channel 34. The positions of the lower perimeter plate 13 and the lens connection seat 3 are limited by the first positioning block 121 to ensure the accuracy of the positions between the lower perimeter plate 13 and the lens connection seat 3.

[0053] Further, third positioning channels 133 are opened at the two ends of the lower perimeter plate 13. The third positioning channels 133 are communicated with the limiting channels 31. An outwardly protruding second positioning block 122 is arranged on the body connection seat 12. The second positioning block 122 passes through the third positioning channel 133 and extends into the limiting channel 31. The side surfaces between the second positioning block 122 and the limiting block 312 are in mutual abutting contact. The positions of the lower perimeter plate 13 and the lens connection seat 3 are further limited. At the same time, the second positioning block 122 and the two first positioning blocks 121 form a triangle to jointly limit the lower perimeter plate 13 and the lens connection seat 3, ensuring the concentricity between the limiting channel 31 and the connection handle 134, providing a good rotation space for the bending plate 211, and avoiding the non-concentricity between the two, resulting in a gradual reduction in the distance between the rotation spaces and affecting the rotation of the bending plate 211.

[0054] Please refer to Figure 3 , 6 and Figure 9 As shown, in this embodiment, on the outer sides of both ends of the lower peripheral plate 13, there are inwardly recessed grooves 131. The lens connecting seat 3 is embedded in the recessed grooves 131. The recessed grooves 131 accommodate the lens connecting seat 3, and the top surface of the lens connecting seat 3 is flush with the notch of the recessed grooves 131, reducing the width of the connection position of the lower peripheral plate 13, the upper peripheral plate 11 and the lens 2, making the space utilization rate of the overall internal structure of the helmet higher. Further, the two adjacent inner side surfaces of the recessed grooves 131 are flat surfaces 1311. On one side of the lens connecting seat 3, there is a limiting protrusion 36 extending outward, and the outer side surface of the limiting protrusion 36 fits with the flat surface 1311. The flat surfaces 1311 between the recessed grooves 131 and the limiting protrusion 36 fit with each other, and the lens connecting seat 3 is limited by the flat surface 1311 to prevent the lens connecting seat 3 from rotating and affecting the disassembly and assembly of the lens 2.

[0055] In this embodiment, an installation notch 1312 is provided at the bottom of the recessed grooves 131, and an installation tongue 35 protruding outward is provided on the bottom surface of the lens connecting seat 3. The installation tongue 35 is inserted into the installation notch 1312 to limit the lens connecting seat 3 and ensure the stability of the lens connecting seat 3 in the recessed grooves 131.

[0056] In this embodiment, on both sides of the bottom of the lens 2, there are push blocks 24. The top surface of the push block 24 has a curved surface 241 with a central inward concavity, and multiple inwardly recessed grooves 242 are provided on the bottom surface of the push block 24. Through the push blocks 24 on both sides, the wearer can directly apply an upward opening thrust or a downward closing pressure to the lens 2 with either the left hand or the right hand, resulting in a high usage experience. And the curved surface 241 fits well with the hand, facilitating the user to apply a downward pressure. By using the multiple grooves 242 on the bottom surface of the push block 24, the friction between the push block 24 and the hand is increased, enabling the user to better apply an upward opening thrust. And by providing the push blocks 24, it is avoided that the user's hand directly contacts the lens 2 and affects the clarity of the lens 2.

[0057] The above is only the preferred specific embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any change or replacement that can be easily thought of by those skilled in the art within the technical scope disclosed by the present utility model should be covered within the protection scope of the present utility model. Therefore, the protection scope of the present utility model should be subject to the protection scope of the claims.
