[0001] This utility model relates to the field of helmet technology, specifically to a helmet outer lens and lens mount connection structure and a helmet. Background Technology

[0002] The outer visor of a helmet is typically attached to the helmet via an outer visor mounting bracket, which is rotatably connected to the helmet body by bolts. Special tools are usually required to assemble and disassemble the outer visor and the mounting bracket, resulting in difficulties and inconvenience. Utility Model Content

[0003] Based on the above description, this utility model provides a connection structure between the outer lens and the mount of a helmet, in order to solve the problem that the outer lens and the mounting base require professional tools to disassemble and assemble, which is difficult to disassemble and assemble and inconvenient to use.

[0004] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: In a first aspect, this application provides a connection structure between a helmet outer lens and a lens mount, comprising: Lens and lens mount, wherein the lens mount is provided with bolt holes; The mounting component is disposed between the lens and the lens base and is connected to the lens base. The mounting component has a first limiting surface and a second limiting surface on the side near the lens base. The first limiting surface and the second limiting surface are distributed circumferentially along the bolt hole. The first limiting surface has a first notch that passes through the bolt hole axially, and the second limiting surface has a second notch that passes through the bolt hole axially. A first limiting member and a second limiting member, wherein the first limiting member is located between the first limiting surface and the lens base, and the second limiting member is located between the second limiting surface and the lens base. The first limiting member can pass through a first notch, and the second limiting member can pass through a second notch. Both the first limiting member and the second limiting member are connected to the lens, and the lens can rotate relative to the mounting member around the bolt hole axis. The lens can rotate until the first limiting member is located at the first notch and the second limiting member is located at the second notch. A locking member is disposed between the lens and the lens mount and connected to the lens mount. The locking member is movable relative to the lens mount. The locking member includes a first position and a second position. In the first position, the locking member blocks the first notch and the second notch. In the second position, the locking member opens the first notch and the second notch. The locking member is adapted to be operated by a person to move between the first position and the second position.

[0005] Preferably, the locking member includes a first limiting part and a second limiting part, wherein the first limiting part is used to block the first gap and the second limiting part is used to block the second gap.

[0006] Preferably, the locking member can move relative to the mirror base in a direction perpendicular to the axis of the bolt hole, the first notch is located on the moving path of the first limiting part, and the second notch is located on the moving path of the second limiting part.

[0007] Preferably, an elastic element is provided between the locking member and the mirror base, and the locking member overcomes the elastic force of the elastic element when it moves from the first position to the second position.

[0008] Preferably, the elastic element is a spring.

[0009] Preferably, the mounting component has a mounting hole coaxial with the bolt hole, and the lens is connected to a mounting ring coaxially passing through the mounting hole. The mounting ring is restricted to move radially relative to the mounting component, and the first limiting member is connected to the mounting ring.

[0010] Preferably, the mounting component is provided with a deformable part, and the deformable part is provided with a plurality of limiting protrusions, which are distributed at intervals along the circumference of the bolt hole; The lens is provided with a limiting post, and the limiting post is provided with a limiting groove on the side facing the mounting component; The deformable part can elastically deform to move the limiting protrusion away from the limiting post. When the deformable part is not deformed, the limiting protrusion is located on the path of the limiting post as the lens rotates. It is suitable for the deformable part to elastically deform through the limiting post when the lens rotates. When the limiting post rotates to the point where the limiting groove is aligned with any of the limiting protrusions, the deformable part restores its deformation to embed the limiting protrusion into the limiting groove.

[0011] Preferably, when the lens rotates relative to the lens mount, it can rotate to cover or expose the locking member.

[0012] Secondly, this application provides a helmet that employs the helmet outer lens and lens mount connection structure described above.

[0013] Compared with the prior art, the technical solution of this application has at least the following beneficial technical effects: This application provides a mounting component that connects the lens and the lens mount. During lens installation, a movable locking component opens the first and second notches, allowing the first limiting component to move through the first notch to the space between the first limiting surface of the mounting component and the lens mount. The second limiting component moves through the second notch to the space between the second limiting surface of the mounting component and the lens mount. The locking component is then moved to block the first and second notches. At this point, the locking component restricts the first and second limiting components from passing through the first and second notches, allowing the lens to rotate relative to the mounting component around the bolt hole axis on the lens mount. During rotation, the lens will not detach from the mounting component due to the limiting positions of the mounting component and the locking component, thus rotatably mounting the lens onto the lens mount. When lens removal is required, the lens is rotated until the first limiting component is located at the first notch, and the second limiting component is located at the second notch. The locking component is then moved to open the first and second notches, allowing the first and second limiting components to move through the first and second notches simultaneously. The first and second limiting components then detach from the mounting component, thus removing the lens. The lens is easy and convenient to install and remove, and the installation is stable.

[0021] Reference Figures 1 to 8 As shown, this application provides a helmet outer lens and lens mount connection structure, including lens 1, lens mount 2, mounting component 3 and locking component 4.

[0022] Reference Figure 2 As shown, the lens mount 2 is provided with a bolt hole 21, through which a bolt passes to rotatably mount the lens mount 2 onto the helmet body 44. When the lens mount 2 is connected to the helmet body 44, it can rotate relative to the helmet body 44 around the bolt axis, i.e., the bolt hole 21 axis.

[0023] Reference Figure 2 As shown, the mounting component 3 is disposed between the lens 1 and the lens base 2. The mounting component 3 is connected to the lens base 2 and is used for mounting the lens 1.

[0024] Reference Figure 3 As shown, specifically, the mounting component 3 has a first limiting surface 31 and a second limiting surface 32 on the side near the mirror base 2. The first limiting surface 31 and the second limiting surface 32 are distributed circumferentially along the bolt hole 21. The first limiting surface 31 has a first notch 33 that penetrates the bolt hole 21 in the axial direction, and the second limiting surface 32 has a second notch 34 that penetrates the bolt hole 21 in the axial direction.

[0025] Reference Figure 3 As shown, the lens 1 is connected to a first limiting member 11 and a second limiting member 12. The first limiting member 11 is located between the first limiting surface 31 and the lens base 2, and the second limiting member 12 is located between the second limiting surface 32 and the lens base 2. The first limiting member 11 can pass through the first notch 33, and the second limiting member 12 can pass through the second notch 34. The lens 1 can rotate relative to the mounting member 3 around the axis of the bolt hole 21. The lens 1 can rotate until the first limiting member 11 is located at the first notch 33 and the second limiting member 12 is located at the second notch 34.

[0026] Reference Figure 3As shown, when the first limiting member 11 is not rotated to the position of the first notch 33, the second limiting member 12 is also not at the position of the second notch 34. At this time, under the limiting action of the mounting member 3, both the first limiting member 11 and the second limiting member 12 are restricted from moving away from the lens base 2 until they are detached from the mounting member 3. In the design, the first limiting member 11 and the second limiting member 12 are respectively in contact with the first limiting surface 31 and the second limiting surface 32, and the lens 1 and the mounting member 3 are in contact on the side away from the lens base 2, so as to restrict the lens 1 from moving relative to the mounting base along the axial direction of the bolt hole 21, so that the lens 1 is stably installed on the mounting member 3.

[0027] Reference Figure 2 and Figure 4 As shown, the locking member 4 is used to restrict the first limiting member 11 from passing through the first notch 33 and the second limiting member 12 from passing through the second notch 34. The locking member 4 is disposed between the lens 1 and the lens base 2 and connected to the lens base 2. The locking member 4 can move relative to the lens base 2. The locking member 4 includes a first position and a second position. When the locking member 4 is in the first position, it blocks the first notch 33 and the second notch 34. When the locking member 4 is in the second position, it opens the first notch 33 and the second notch 34. The locking member 4 is adapted to be operated by a person to move between the first position and the second position.

[0028] When installing lens 1, first move locking member 4 to the second position to open the first notch 33 and the second notch 34, move the first limiting member 11 through the first notch 33 to the space between the first limiting surface 31 of the mounting member 3 and the lens base 2, and move the second limiting member 12 through the second notch 34 to the space between the second limiting surface 32 of the mounting member 3 and the lens base 2.

[0029] Then, the locking member 4 is moved to the first position to block the first notch 33 and the second notch 34. At this time, under the obstruction of the locking member 4, the first limiting member 11 is restricted from passing through the first notch 33, and the second limiting member 12 is restricted from passing through the second notch 34. During the rotation of the lens 1 relative to the mounting member 3, the mounting member 3 and the locking member 4 cooperate to limit the movement and will not detach from the mounting member 3, thereby rotatably mounting the lens 1 on the lens base 2.

[0030] When lens 1 needs to be removed, rotate lens 1 until the first limiting member 11 is located at the first notch 33, and the second limiting member 12 is located at the second notch 34. Move the locking member 4 to the second position to open the first notch 33 and the second notch 34, so that the first limiting member 11 moves through the first notch 33 and the second limiting member 12 moves through the second notch 34. The first limiting member 11 and the second limiting member 12 disengage from the mounting member 3, that is, lens 1 disengages from the mounting member 3, thereby removing lens 1. The method of removing and installing lens 1 is simple and convenient, and the installation is stable.

[0031] Reference Figure 3 and Figure 5As shown, the mounting component 3 is fixed to the lens base 2 by two first buckles 35. Two first locking holes 22 are provided on the lens base 2. The mounting component 3 is located on the side of the lens base 2 close to the lens 1. The two first buckles 35 pass through the two first locking holes 22 respectively and abut against the side of the lens base 2 away from the lens 1. The body of the mounting component 3 can be elastically deformed so that during installation, the two first buckles 35 can pass through the two first locking holes 22 respectively and move to the side of the lens base 2 away from the lens 1.

[0032] Reference Figure 3 and Figure 6 As shown, the mounting component 3 has a mounting hole 36 coaxial with the bolt hole 21. The lens 1 is connected to a mounting ring 13 coaxially inserted in the mounting hole 36. The mounting ring 13 is restricted to move radially relative to the mounting component 3. The first limiting member 11 is connected to the mounting ring 13. This arrangement can improve the connection stability between the lens 1 and the mounting component 3 and ensure the stability of the lens 1 when it rotates.

[0033] Reference Figure 3 As shown, in this embodiment, the first limiting surface 31 and the second limiting surface 32 are arranged at intervals along the circumference of the mounting hole 36, the first notch 33 passes through the mounting hole 36 in the radial direction, so that the entire mounting part 3 can elastically deform in the radial direction of the mounting hole 36, and the second notch 34 is provided on the outer edge of the mounting part 3 to ensure the strength of the mounting part 3.

[0034] The first limiting member 11 is connected to the mounting ring 13, thus creating a gap between it and the lens 1, while the second limiting member 12 is connected to the lens 1 via a connecting part. In this embodiment, both the first limiting member 11 and the second limiting member 12 are limiting blocks.

[0035] Reference Figure 4 As shown, the locking member 4 is used to open or block the first notch 33 and the second notch 34, and specifically includes a first limiting part 41 and a second limiting part 42. The first limiting part 41 is used to block the first notch 33, and the second limiting part 42 is used to block the second notch 34.

[0036] Since the first limiting surface 31 and the second limiting surface 32 are spaced apart along the circumference of the bolt hole 21, the first limiting part 41 and the second limiting part 42 are also spaced apart along the circumference of the bolt hole 21.

[0037] Reference Figure 7 As shown, specifically, the locking member 4 is configured to move relative to the mirror base 2 in a direction perpendicular to the axis of the bolt hole 21. The first notch 33 is located on the movement path of the first limiting part 41, and the second notch 34 is located on the movement path of the second limiting part 42.

[0038] Reference Figure 7As shown, when the first limiting part 41 moves into the first notch 33, the first limiting member 11 rotates to the first notch 33 and is restrained from passing through the first notch 33 by abutting against the first limiting part 41. When the first limiting part 41 moves outside the first notch 33, the first limiting member 11 can pass through the first notch 33 and detach from the mounting member 3. When the second limiting part 42 moves to the second notch 34, the second limiting member 12 rotates to the second notch 34 and is restrained from passing through the second notch 34 by abutting against the second limiting part 42. When the second limiting part 42 moves outside the second notch 34, the second limiting member 12 can pass through the second notch 34 and detach from the mounting member 3.

[0039] Reference Figure 4 and Figure 5 As shown, the locking member 4 is fixed to the lens base 2 by two second latches 43. The lens base 2 also has two second locking holes 23. The locking member 4 is located on the side of the lens base 2 closest to the lens 1. The two second latches 43 pass through the two second locking holes 23 respectively and abut against the side of the lens base 2 furthest from the lens 1. Furthermore, the second latches 43 can move radially relative to the lens base 2 along the bolt hole 21 within the second locking holes 23, allowing the locking member 4 to move relative to the lens base 2.

[0040] Reference Figure 4 As shown, specifically, the locking member 4 includes a main body 44, with a first limiting part 41 and a second limiting part 42 both connected to the main body 44. The second limiting part 42 is connected to the main body 44 via a connecting arm 45. Two second latches 43 are respectively disposed on the main body 44 and the connecting arm 45. The connecting arm 45 can elastically deform relative to the main body 44, allowing the two second latches 43 to pass through the two second locking holes 23 and move to the side of the lens mount 2 away from the lens 1 during installation. This securely mounts the locking member 4 onto the lens mount 2.

[0041] Reference Figure 4 As shown, in order to improve the support strength of the second limiting part 42 for the second limiting member 12, the second limiting part 42 is provided with a connecting buckle 46. The connecting buckle 46 abuts against the second support surface. When the second limiting member 12 rotates to abut against the second limiting part 42, the pressure is transmitted to the second support surface, i.e., the mounting member 3, through the connecting buckle 46, so as to prevent the second limiting member 12 from disengaging from the second notch 34 due to the elastic deformation of the connecting arm 45.

[0042] Reference Figure 4 and Figure 5As shown, furthermore, an elastic element 5 is provided between the locking member 4 and the lens mount 2. When the locking member 4 moves from the first position to the second position, it overcomes the elastic force of the elastic element 5. The elastic force of the elastic element 5 is used to keep the locking member 4 in the first position, that is, to prevent the first limiting member 11 from disengaging from the first notch 33 and to prevent the second limiting member 12 from disengaging from the second notch 34, so that the lens 1 is stably installed on the mounting member 3, and to prevent the lens 1 from falling off during normal use.

[0043] Specifically, the elastic element 5 is a spring, with the spring axis perpendicular to the axis of the bolt hole 21. A spring hole 24 is provided on the mirror base 2, and a support protrusion 47 protruding from the spring hole 24 is provided on the locking element 4. The spring is set in the spring hole 24, with one end abutting against the support protrusion 47 and the other end abutting against the mirror base 2. Guide posts are provided on both the support protrusion 47 and the mirror base 2, and the two ends of the spring are respectively sleeved on the two guide posts.

[0044] Reference Figure 8 As shown, further, in the design, the lens 1 is configured to rotate relative to the mount 2 to either cover or expose the locking member 4. Specifically, when the lens 1 is in the downward closed state on the helmet, the locking member 4 is covered, maintaining the helmet's aesthetic appearance during normal use. When the lens 1 is in the upward open state, the locking member 4 is exposed, and at this time, the first limiting member 11 is located at the first notch 33, and the second limiting member 12 is located at the second notch 34, so that the operator can manipulate the locking member 4 to move and remove the lens 1 from the mounting member 3.

[0045] Reference Figure 3 and Figure 6 As shown, in order to achieve the function of suspending the lens 1 when it rotates to the designed angle on the helmet, a deformation part 37 is provided on the mounting part 3. The deformation part 37 is provided with multiple limiting protrusions 38, which are distributed circumferentially along the bolt holes 21. The lens 1 is provided with a limiting post 14, and the limiting post 14 is provided with a limiting groove 141 on the side facing the mounting part 3. The deformation part 37 can elastically deform to make the limiting protrusions 38 move away from the limiting post 14. When the deformation part 37 is not deformed, the limiting protrusions 38 are located on the path of the limiting post 14 as the lens 1 rotates. It is suitable for the deformation part 37 to be elastically deformed by the limiting post 14 when the lens 1 rotates. When the limiting post 14 rotates to the point where the limiting groove 141 is aligned with any limiting protrusion 38, the deformation part 37 restores its deformation so that the limiting protrusion 38 is embedded in the limiting groove 141.

[0046] When lens 1 rotates relative to mounting member 3, the limiting post 14 and the limiting protrusion 38 abut against and continue to rotate, applying pressure to the limiting protrusion 38, causing the deformation part 37 to elastically deform until the limiting protrusion 38 is outside the movement path of the deformation part 37. At this time, the limiting post 14 can continue to rotate until the limiting groove 141 and the limiting protrusion 38 are aligned. Then, the deformation part 37 recovers its deformation, causing the limiting protrusion 38 to embed into the limiting groove 141. At this time, the limiting protrusion 38 and the limiting post 14 cooperate to provide resistance to the rotation of lens 1. If lens 1 needs to continue rotating, pressure needs to be applied to lens 1. The limiting post 14 applies pressure to the limiting protrusion 38 to overcome the elastic force of the deformation part 37, causing the limiting protrusion 38 to move away from the limiting post 14. In the design, the weight of lens 1 is not enough to overcome the elastic force of the deformation part 37 to rotate, thus realizing the hovering function of lens 1 at the designed angle. Multiple limiting protrusions 38 allow lens 1 to hover at multiple angles.

[0047] Reference Figure 3 As shown, in this embodiment, the mounting member 3 is provided with a deformation groove 39 that extends through the mounting hole 36 in the axial direction. The deformation groove 39 and the mounting hole 36 are distributed at intervals in the radial direction of the mounting hole 36. The part of the mounting member 3 located on the side of the deformation groove 39 away from the mounting hole 36 forms a deformation part 37. The limiting protrusion 38 is provided on the outer edge of the deformation part 37. The limiting post 14 is provided to be distributed in the radial direction of the bolt hole 21 along with the mounting member 3.

[0048] Reference Figure 9 As shown, this embodiment also provides a helmet, which adopts the helmet outer lens and lens mount connection structure described above.

[0049] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.

The helmet outer lens and rim connection structure of claim 1, wherein: The mounting component (3) is provided with a deformation part (37), and the deformation part (37) is provided with a plurality of limiting protrusions (38), which are distributed circumferentially along the bolt hole (21); The lens (1) is provided with a limiting post (14), and the limiting post (14) is provided with a limiting groove (141) on the side facing the mounting part (3); The deformable part (37) can be elastically deformed to move the limiting protrusion (38) away from the limiting post (14). When the deformable part (37) is not deformed, the limiting protrusion (38) is located on the path of the limiting post (14) as the lens (1) rotates. It is suitable for the deformable part (37) to be elastically deformed by the limiting post (14) when the lens (1) rotates. When the limiting post (14) rotates to the point where the limiting groove (141) is aligned with any of the limiting protrusions (38), the deformable part (37) restores its deformation so that the limiting protrusion (38) is embedded in the limiting groove (141).

8. The helmet outer mirror and mirror mount connection structure of claim 1, wherein: When the lens (1) rotates relative to the lens base (2), it can rotate to cover or expose the locking member (4).

9. A helmet characterized by: The helmet outer lens and lens mount connection structure is adopted as described in any one of claims 1-8.
