[0045] When the first quick-release assembly 400 rotates until the handle 420 moves radially, driving the stop pin 440 out of the quick-release slot 250, each pair of arms 120 can be inserted into or removed from the first quick-release socket 410 and the second quick-release socket 510, respectively, to accommodate the first waist-shaped column 210 and the second waist-shaped column 310 in the corresponding slot 130. Each pair of arms 120 is provided with an arm stopper 160 at the middle portion for elastically engaging with the corresponding first limiting block 140 and second limiting block 150. When the first quick-release assembly 400 rotates until the handle 420 moves radially, driving the stop pin 440 out of the lower release slot 240, the first limiting block 140 and the second limiting block 150 are respectively engaged with the corresponding arm stopper 160. When the first quick-release assembly 400 rotates and drives the stop pin 440 to move along the gear ring 220, the second quick-release assembly 500 drives the positioning block 520 to move along the positioning hole 320.

[0046] The multifunctional helmet visor quick-release mechanism provided in the embodiment of the present application is used to quickly attach and detach different visors 110 to and from the helmet 100, thereby facilitating the user to equip and replace different visors 110 according to the usage environment and task requirements. During assembly, the first mounting seat 200 and the second mounting seat 300 are pre-fixed to the left and right sides of the helmet 100 by screws, respectively, so that the first quick-release assembly 400 and the second quick-release assembly 500 are rotatably connected to the two sides of the helmet 100. At this time, the stop pin 440 on the handle 420 connected to the first quick-release assembly 400 on the left side of the helmet 100 is engaged with the quick-release slot 250, and the first waist-shaped column 210 and the second waist-shaped column 310 provided on the first mounting seat 200 and the second mounting seat 300 are aligned with the first quick-release socket 410 and the second quick-release socket 510 on the first quick-release assembly 400 and the second quick-release assembly 500, respectively.

[0047] When the user detachably connects the goggles 110 to the first quick-release assembly 400 and the second quick-release assembly 500 through the support arms 120 connected on both sides, the user inserts the two support arms 120 away from the end of the goggles 110 into the first quick-release socket 410 and the second quick-release socket 510 on the first quick-release assembly 400 and the second quick-release socket 510 on the first quick-release assembly 400 and the second quick-release assembly 500, respectively, so that the first waist-shaped column 210 and the second waist-shaped column 310 respectively pass through the limiting groove 132 on the card slot 130 at the end of the two support arms 120 and enter the circular groove 131, and then the user pushes the handle 420 to move radially along the corresponding first waist-shaped column 210 to drive the stop pin 440 to disengage the quick-release groove 250, and then the user moves along the first waist-shaped column 210 to move radially. A waist-shaped column 210 rotates the handle 420 circumferentially, so that the handle 420 drives the stop pin 440 to move to align with the lowering groove 240 or the stowing groove 230 and then releases it. At this time, the handle 420 drives the first quick-release assembly 400, the support arm 120 and the goggles 110 to rotate to the use position in front of the helmet 100 or the stowed position above the helmet 100, and the spring 430 pushes the moving handle 420 to reset and snap into the lowering groove 240 or the stowing groove 230 to lock the position of the goggles 110 and the helmet 100, thereby fixing the goggles 110 to the helmet 100 in the use position or the stowed position, making it convenient to use and stow the goggles 110.

[0048] When the user needs to replace the goggles 110, he only needs to push the handle 420 to move the compression spring 430 radially. At this time, the stop pin 440 on the handle 420 on the left side of the helmet 100 will disengage from the lowering slot 240 or the retracting slot 230 to release the lock, and continue to rotate the handle 420 to drive the support arm 120 and the goggles 110 to rotate until the stop pin 440 is aligned with the quick-release slot 250 and then released. The spring 430 pushes the moving handle 420 to reset and snap into the quick-release slot 250. At this time, the first waist-shaped column 210 and the second waist-shaped column 310 in the circular groove 131 on the card slot 130 at the end of the two support arms 120 are separated. The user can align the first waist-shaped column 210 and the second waist-shaped column 310 with the limiting grooves 132 of the two card slots 130 respectively, and disengage the two arms 120 from the first quick-release socket 410 and the second quick-release socket 510 to separate them, thereby separating the two arms 120 and the goggles 110 from the first quick-release assembly 400, the second quick-release assembly 500 and the helmet 100, and connect the other goggles 110 and the arms 120 connected on both sides to the helmet 100 through the first quick-release assembly 400 and the second quick-release assembly 500.

[0049] When the user connects the goggles 110 and the arms 120 connected on both sides thereof to the helmet 100 through the first quick-release assembly 400 and the second quick-release assembly 500, the locking block 260 hinged to the first mounting seat 200 can be rotated so that the locking block 260 is rotated to be mounted on the stop pin 440 that is inserted into the quick-release slot 250 for locking, thereby using the locking block 260 to lock the position of the stop pin 440. At this time, the user cannot push the handle 420 to move radially along the first waist-shaped column 210 to drive the stop pin 440 to move out of the quick-release slot 250 for replacement.

[0050] The second mounting seat 300 is connected to a rotatable L-shaped positioning block 340 via a rotating shaft 330. A torsion spring 350 is connected to the rotating shaft 330 for driving the positioning block 340 to press against the second mounting seat 300. A positioning hole 320 is formed between the positioning block 340 and the second mounting seat 300. The second quick-release assembly 500 is connected to a positioning block 520 inserted into the positioning hole 320. When the user pushes the handle 420 to move radially along the corresponding first waist-shaped column 210, the blocking pin 440 is disengaged. After exiting the quick-release slot 250 and rotating around the first waist-shaped column 210, the positioning block 520 of the second quick-release assembly 500 is driven to move along the positioning hole 320 by the two supporting arms 120 and the goggles 110, so that the positioning block 520 and the positioning hole 320 cooperate to ensure that the second quick-release assembly 500 rotates smoothly and synchronously with the handle 420 and the first quick-release assembly 400; the user can push the positioning block 340 to overcome the elastic force of the torsion spring 350 and rotate around the rotating shaft 330 to open the positioning hole 320.

[0051] The first mounting seat 200 and the second mounting seat 300 are respectively provided with a first limit block 140 and a second limit block 150, and each pair of support arms 120 is respectively provided with a support arm stopper 160 for elastically engaging with the corresponding first limit block 140 and the second limit block 150. When the first quick-release assembly 400 is rotated until the handle 420 moves radially to drive the stop pin 440 out of a lowering groove 240, the first limit block 140 and the second limit block 150 are respectively engaged with the corresponding support arm stopper 160, thereby When the goggles 110 are rotated to the lowered use position, the first limit block 140 and the second limit block 150 are respectively engaged with the corresponding support arm block 160 to fix the position of the goggles 110, thereby improving the stability of the use of the goggles 110. When the goggles 110 are not in use, the goggles 110 are rotated relative to the helmet 100 to drive the support arm block 160 of the support arm 120 to separate from the first limit block 140 and the second limit block 150 of the first mounting seat 200 and the second mounting seat 300.

[0052] In other optional embodiments, the shape of the locking block 260 can also be other shapes such as N-shape, C-shape, etc.

[0053] The embodiments described above are part of the embodiments of the present application, rather than all of the embodiments. The detailed description of the embodiments of the present application is not intended to limit the scope of the present application for protection, but merely represents selected embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.
