[0033] The existing rotating lens base structure for a helmet cannot meet the needs of users for quick manual disassembly and automatic tightness of the lens when closed.

[0034] To solve the above technical problems, the present embodiment provides a rotating lens base structure for a helmet. Figure 1 is a perspective view of a rotating lens base structure for a helmet in an embodiment of the present application, Figure 2 is an exploded view of a rotating lens base structure for a helmet in an embodiment of the present application, Figure 3 is a perspective view of a rotating lens base structure for a helmet in an embodiment of the present application, Figure 4 is a perspective view of a helmet in an embodiment of the present application, Figure 5 is an exploded view of a helmet in an embodiment of the present application.

[0035] The rotating lens base structure of the helmet of the present embodiment comprises a base body 1, a sliding block 2 and a radial latch 3.

[0036] The base body 1 is used to connect the helmet body 4 and serves as the mounting carrier of the sliding block 2 and the radial latch 3. The base body 1 is provided with a hook rail 11 for the rotation of the lens 5, and the hook rail 11 is provided with a notch 12.

[0037] The sliding block 2 is slidably connected with the base body 1 and is provided with a first elastic member 6 between the base body 1 and the sliding block 2, the first elastic member 6 is configured to drive the sliding block 2 to move towards the lens 5, and the sliding block 2 is provided with a pivot 21 for connecting the lens 5.

[0038] The radial latch 3 is rotatably connected with the base body 1 through a rotating shaft, and is provided with a push block 31 for controlling the rotation of the radial latch 3 and a latch 32 for limiting the lens 5 on both sides of the rotating shaft, and the radial latch 3 is provided with a second elastic member 7 between the base body 1 and the radial latch 3, the second elastic member 7 is configured to drive the radial latch 3 to rotate around the rotating shaft to the locking position.

[0039] Wherein, the lens 5 is provided with an outer ring 51 rotatably sleeved with the pivot 21, and a hook 52 located outside the outer ring 51, the hook 52 is slidably arranged in the hook rail 11, so that the lens 5 is fixed relative to the sliding block 2 in the axial direction of the pivot 21; in the locking position, the latch 32 is located at the notch 12 to prevent the hook 52 from disengaging from the hook rail 11, so that the lens 5 remains engaged with the pivot 21; when the push block 31 is pushed to rotate the radial latch 3 against the elastic force of the second elastic member 7, the latch 32 is located outside the notch 12, so that the hook 52 can disengage from the hook rail 11, and the lens 5 can be disengaged from the sliding block 2 along the axial direction of the pivot 21.

[0040] Illustratively, the latch and / or the hook edge is provided with a chamfer.

[0041] The rotating lens base structure of the above technical solution drives the sliding block 2 to move towards the lens 5 in a close direction by the first elastic member 6, so that the lens 5 can be automatically closed and fixed on the edge of the viewing window 40 at the front end of the helmet when the lens 5 is closed. At the same time, the second elastic member 7 drives the radial plug 3 to rotate around the rotating shaft to the locking position. When the plug 32 is located in the notch 12 at the locking position, the hook 52 is prevented from being disengaged from the hook rail 11, that is, the lens 5 is fixed in the axial direction of the pivot 21 and the outer ring 51, so that the lens 5 is kept in cooperation with the pivot 21. When the radial plug 3 is rotated against the elastic force of the second elastic member 7 by pushing the push block 31, the plug 32 is located outside the notch 12, that is, the axial fixation of the hook 52 is cancelled, so that the hook 52 can be disengaged from the hook rail 11, and the lens 5 can be disengaged from the sliding block 2 in the axial direction of the pivot 21. In operation, the lens 5 only needs to be disassembled by first pushing the push block 31 to make the plug 32 located outside the notch 12, and then pulling out the end of the lens 5 cooperating with the sliding block 2 in the direction away from the sliding block 2, so that the outer ring 51 is disengaged from the cooperation with the pivot 21. When the lens 5 is installed, only the plug 32 is aligned with the notch 12, and then the lens 5 is directly pressed into the hook rail 11 by means of the chamfered corner of the hook 52 and the compression deformation of the second elastic member 7. It is also important that the radial plug 3 adopts a rotating design and is actuated by a pushing force, which is different from the common straight rail type tension force actuation. When the lens 5 is disassembled, it is easier to hold the helmet body and operate conveniently. As can be seen, the rotating lens base structure of the above technical solution for the helmet and the helmet can be quickly disassembled by hand for cleaning the lens 5 or replacing a new lens 5. Secondly, the lens 5 can be automatically closed when it is closed, which enriches the functionality of the helmet lens 5.

[0042] In an embodiment in which the sliding block 2 is slidably connected with the base body 1, the base body 1 is provided with a sliding block sliding groove 13 and a sliding block rail 14 at the bottom and the side of the sliding block 2 respectively, and the sliding block 2 is provided with a first convex portion 22 and a second convex portion 23 which are slidably matched with the sliding block sliding groove 13 and the sliding block rail 14 respectively. For example, the first convex portion 22 is located in the sliding block sliding groove 13, and the second convex portion 23 is located in the sliding block rail 2 and extends in the same direction. The sliding block sliding groove 13 and the sliding block rail 14 limit the sliding block 2 on the base body 1, so that the sliding block 2 can only slide relative to the base body 1, but cannot rotate. Through the cooperation of the first convex portion 22 and the second convex portion 23 with the sliding block sliding groove 13 and the sliding block rail 14, the reliability of the connection between the sliding block 2 and the base body 1 and the stability during sliding can be improved.

[0043] It can be understood that the sliding block 2 and the base body 1 can also be slidably connected through existing linear sliding rails and other sliding structures.

[0044] The first elastic member 6 and the second elastic member 7 can be elastic blocks or springs with elastic deformation capability. In an example, the first elastic member 6 and the second elastic member 7 are springs. In order to improve the stability of the spring deformation, the base body 1 is provided with a spring groove 15, and a positioning column is arranged in the spring groove 15. The spring is arranged in the spring groove 15, and one end of the spring is sleeved on the positioning column, and the other end abuts against the sliding block 2 or the radial pin 3.

[0045] In an example, the positioning column is connected to the base body 1 by threading or is integrally formed on the base body 1.

[0046] In order to make the radial pin 3 more stably arranged on the base body 1, the radial pin 3 is provided with a tenon 33. In an example, the tenon 33 is fixed on the radial pin 3 by integral molding. The base body 1 is provided with a clamping groove 16. When the radial pin 3 is in the locking position, the tenon 33 is located in the clamping groove 16. The groove wall of the clamping groove 16 limits the tenon 33 in the axial direction of the rotating shaft, so that the radial pin 3 cannot be separated from the base body 1. At the same time, the clamping groove 16 can also guide the movement of the tenon 33.

[0047] In order to make the lens 5 have a one-key micro-opening function, the lens 5 is provided with a micro-opening column foot 53. The helmet rotating lens base structure further includes a circumferential pin 8 opposite to the micro-opening column foot 53. The circumferential pin 8 is slidably arranged on the base body 1 and is provided with a third elastic member 9 between the base body 1 and the circumferential pin 8. The third elastic member 9 is configured to drive the circumferential pin 8 to push the lens 5 to move a preset distance in the opening direction when the lens 5 is opened. When the lens 5 is closed, the micro-opening column foot 53 pushes the circumferential pin 8, and the third elastic member 9 is compressed. When the lens 5 is opened, the elastic force generated by the compression of the third elastic member 9 pushes the circumferential pin 8, and the circumferential pin 8 pushes the lens 5 to move a preset distance. The preset distance can be designed according to the size of the micro-opening required by the lens 5, so that the lens 5 is automatically opened to a certain size after being opened, and meets the needs of the user in use, such as defogging and air exchange.

[0048] In an example, the third elastic member 9 is a spring, and is installed on the base body 1 through the spring groove 15 and the positioning column.

[0049] In order to make the lens 5 have multiple angle gears to adapt to the use requirements of windproof, rainproof and warm-keeping when closing, defogging and air exchange when slightly opening and half opening, and heat dissipation when fully opening, the lens 5 is provided with a gear column foot 54, and the base body 1 is provided with a plurality of tooth grooves 17 which are arranged at intervals on a rotating path with the outer circle 51 of the gear column foot 54 as the rotating center and are used for limiting the gear column foot 54. The tooth grooves 17 have elastic deformation capacity, so that the gear column foot 54 can move between the tooth grooves 17. When the gear column foot 54 is located in any tooth groove 17, the lens 5 is fixed in position with the base body 1. The number and interval of the tooth grooves 17 can be set according to the required opening angle or the number and interval of the gears of the lens 5. In use, the user rotates the lens 5 to make the gear column foot 54 rotate into one of the tooth grooves 17, so that the lens 5 can be fixed at the corresponding opening gear and angle, thereby improving the convenience of use of the lens 5 and meeting the use requirements in different scenes.

[0050] The embodiment provides a helmet, which comprises the rotating lens base structure for the helmet and further comprises a helmet body 4 and a lens 5, and the base body 1 is fixedly connected with the helmet body 4.

[0051] For example, the helmet body 4 is provided with a viewing window 40, and a group of the rotating lens base structures for the helmet are arranged on both sides of the viewing window 40. The lens 5 is connected with the sliding blocks 2 on both sides of the viewing window 40, so that the viewing window 40 can be opened and closed.

[0052] For example, the edge of the viewing window 40 is provided with a rubber strip. When the lens 5 closes the viewing window 40, the lens 5 is pressed against the rubber strip under the action of the first elastic member 6 and the sliding block 2, so that the viewing window 40 is tightly closed by the lens 5.

[0053] For example, the installation process of the helmet in the above embodiment is as follows:

[0054] Firstly, the sliding block 2 is installed: the sliding block 2 is installed into the inner side of the sliding block rail 14 of the base body 1, and the spring is installed as the first elastic member 6 in the spring groove 15; the tenon 33 and the sliding block rail 14 form a sliding rail, and the sliding block 2 will not fall off when sliding in the sliding rail; the first protruding part 22 of the sliding block 2 and the sliding block sliding groove 13 form a limiting structure to prevent the sliding block from shaking when being actuated.

[0055] Then, the radial bolt 3 is installed: the radial bolt 3 is installed into the bolt rail of the base body 1, the tenon 33 and the bolt rail form a sliding rail, and the radial bolt 3 will not fall off when rotating in the rail; the rotating shaft hole of the radial bolt 3 is installed on the rotating shaft of the radial bolt to form the rotating pivot of the radial bolt 3; the spring is installed as the second elastic member 7 in the spring groove 15 and is located between the radial bolt 3 and the base body 1.

[0056] Then, the circumferential plug 8 is installed: the circumferential plug 4 is installed into the circumferential plug slide rail of the base body 1, and the micro-opened column foot 53 is supported; the spring is installed as the third elastic member 9 in the spring groove 15, and is located between the circumferential plug 4 and the base body 1.
