Description

Protective eyewear and helmet

[0001] This application claims priority to Chinese Patent Application No. 202410685730.3, filed with the Chinese Patent Office on May 30, 2024, the entire contents of which are incorporated herein by reference. Technical Field

[0002] This application relates to the field of safety products technology, such as a protective eye mechanism and a helmet. Background Technology

[0003] A helmet is a protective gear used to protect the head. As a protective tool in transportation such as bicycles and motorcycles, especially for motorcycle riding, it is usually designed with a visor. As an optical device, the visor not only improves vision and protects the eyes, but also has an aesthetic effect. The visor is usually mounted on the helmet using a mounting structure. During use, the area of ​​the visor that performs its function can be adjusted to keep it in a specific position. When it is necessary to replace or maintain the visor, some conventional helmets use a handle-type mounting structure. This structure makes it difficult to detach the visor during disassembly, making replacement or maintenance difficult. Another type of helmet uses a snap-fit ​​structure. While the snap-fit ​​structure makes it easier to detach the visor during disassembly, the interfering relationship between the snap-fit ​​structure and the helmet makes disassembly more cumbersome. Summary of the Invention

[0004] This application provides a protective eye mechanism and a helmet. The protective eye mechanism facilitates the removal of the protective lens, and the removal process is simple and easy to operate, making it convenient to replace or maintain the protective lens.

[0005] This application provides a protective eye device, comprising:

[0006] The protective lenses have clips.

[0007] A base, wherein a locking groove and an unlocking groove are provided on the base, and the locking groove and the unlocking groove are connected;

[0008] The cover plate is configured as an open-shaped shell, and the side wall of the cover plate is provided with a clearance groove. The cover plate is rotatably connected to the base, and the opening of the cover plate faces the base.

[0009] A rotating assembly includes a rotating handle with a locking pin on the rotating handle. The rotating assembly is movably disposed at the opening end of the cover plate and is in transmission cooperation with the cover plate. The locking pin is slidably disposed in the locking groove or the unlocking groove, and the rotation center of the cover plate is offset from the centerline of the rotating assembly.

[0010] A snap-fit ​​assembly includes an elastic element and a snap-fit ​​member. The snap-fit ​​member is connected to the elastic element, and the elastic element is limitedly connected to the rotating assembly and located between the rotating assembly and the cover plate. The snap-fit ​​member can extend out of or retract into the cover plate through the clearance groove.

[0011] When the locking pin is in the locking groove, the snap-fit ​​extends out of the cover plate and engages with the buckle. When the rotating handle is turned so that the locking pin is in the unlocking groove, the snap-fit ​​disengages from the buckle and retracts into the cover plate.

[0012] In some embodiments, the base is further provided with a buffer groove, and the locking groove and the unlocking groove are located on both sides of the buffer groove and are both connected to the buffer groove.

[0013] In some embodiments, a plurality of positioning grooves are provided on the left side wall of the base, and the plurality of positioning grooves are spaced apart along the extending direction of the left side wall. A positioning post is provided on the goggle lens, and the positioning post engages with the positioning groove.

[0014] In some embodiments, the cover plate is provided with a rotating column and an auxiliary component;

[0015] The rotating column is disposed on one side of the cover plate and is rotatably connected to the rotating groove in the base, and the rotating groove is disposed above the side of the unlocking groove;

[0016] The auxiliary component is disposed at the open end of the cover plate, and the auxiliary component slides in the guide limiting groove in the base and drives in the rotating component.

[0017] In some embodiments, two snap-fit ​​members are provided, and correspondingly, two clearance slots are provided. The two snap-fit ​​members are spaced apart in the left-right direction, and the elastic element is disposed between the two snap-fit ​​members.

[0018] In some embodiments, the elastic element is plate-shaped, and two limiting groove groups are provided on the elastic element. A guide protrusion is formed at the connection between the snap-fit ​​member and the elastic element, and the two limiting groove groups are spaced apart in the left-right direction.

[0019] Both of the aforementioned limiting groove groups are disposed on the end face of the elastic member near the rotating assembly, and are limited and engaged with the corresponding limiting pins on the rotating assembly, thereby changing the position of the limiting pins within the limiting groove groups so that the elastic member is in a compressed or retracted state. The guide protrusion is guided and engaged with the corresponding first guide groove on the cover plate.

[0020] In some embodiments, the rotating assembly further includes a rotating switch, the limiting pin being disposed on the end face of the rotating switch near the elastic member, and the rotating switch being connected to the rotating handle.

[0021] In some embodiments, the rotary switch is further provided with an abutment member, and the eye protection mechanism further includes a first reset member and a second reset member;

[0022] The abutting member extends toward the cover plate and abuts against the auxiliary member. Rotating the rotating handle causes the cover plate to rotate.

[0023] The first reset member is disposed between the auxiliary member and the base, and the second reset member is disposed between the abutment member and the cover plate.

[0024] In some embodiments, the end face of the abutment near the cover plate is configured as a first guide surface, and the goggle lens is provided with a second guide surface that guides and cooperates with the first guide surface.

[0025] A helmet, comprising a helmet body and a visor, wherein a base in the visor is connected to the helmet body from the end face away from the visor.

[0026] Compared with related technologies, the protective eye mechanism and helmet provided in this application have the following technical advantages:

[0027] 1. The system includes a locking assembly that engages with the unlocking slot. This assembly is positioned between the rotating component and the cover plate, and is connected to the rotating component for limiting its movement. The rotating component is movably mounted on the cover plate and engages with it in a transmission mechanism. The rotation center of the cover plate is offset from the centerline of the rotating component. Therefore, when the goggles need to be removed, the rotating handle is turned, causing the locking pin in the locking slot to slide into the unlocking slot. At this time, the rotating component rotates around its centerline in a first direction, causing the cover plate to rotate around its rotation center in the same direction. During this process, because the rotating component and the cover plate rotate simultaneously with different rotation centers, the elastic element in the locking assembly is compressed by the rotating component and the cover plate. The locking element connected to the elastic element disengages from the latch and retracts into the cover plate, disengaging the goggles from the locking assembly and facilitating their removal. This allows for subsequent maintenance or replacement of the goggles. When installing the goggles, place the clips on the goggles onto the base, then turn the handle to slide the locking pin in the unlocking groove into the locking groove. At this time, the rotating component rotates around its center line in a second direction opposite to the first direction, causing the cover plate to rotate around its rotation center in the second direction opposite to the first direction. During this process, the rotating component and the cover plate gradually release the compression of the elastic element in the snap-fit ​​component. The elastic element rebounds on its own, causing the snap-fit ​​piece connected to the elastic element to extend out of the cover plate. Simultaneously, press the goggles to engage the clips with the snap-fit ​​piece, thus installing the goggles. Throughout the process, the goggles can be removed and removed simply by turning the handle. The removal and removal process is simple and easy to operate, facilitating the replacement or maintenance of the goggles. Furthermore, the rotating handle helps avoid difficulties in removal and installation caused by interference with the goggles or helmet.

[0028] 2. Since the goggle mechanism is installed on the helmet, when removing the goggles, the latches can be engaged or disengaged by turning the handle, thus completing the installation or removal of the goggle lens. The whole process is simple and easy to operate, and it can avoid the situation of difficulty in disassembly and assembly due to interference with the goggle lens or helmet, further improving the convenience of replacing or maintaining the goggle lens.

Detailed Implementation

[0037] The present application will now be described in detail with reference to the accompanying drawings and embodiments. The specific embodiments described herein are used to explain the present application. For ease of description, only the parts relevant to the present application are shown in the drawings, not all structures.

Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0040] In the description of this embodiment, the terms "upper," "lower," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application. In addition, the terms "first" and "second" are used only for distinction in description and have no special meaning.

[0041] Referring to Figures 1 to 7, the goggle mechanism provided in this embodiment improves the ease of installation and removal of the goggle lens 100. The goggle lens 100 is installed on the helmet through two sets of bases 200 and other components connected to the bases 200. In this embodiment, the structure on the left side of the helmet is taken as an example. Specifically, the helmet includes a helmet body and a goggle mechanism. In the goggle mechanism, the end face of the base 200 facing away from the goggle lens 100 is connected to the helmet body. Since the goggle mechanism is installed on the helmet, when removing the goggle, the locking piece 520 can be engaged or disengaged from the buckle 110 by turning the handle 410, thereby completing the installation or removal of the goggle lens 100. The whole process is simple and easy to operate, and at the same time, it can avoid the situation where the installation and removal are difficult due to interference with the goggle lens 100 or the helmet, further improving the convenience of replacing or maintaining the goggle lens 100.

[0042] The protective eye mechanism includes a protective lens 100, a base 200, a cover plate 300, a rotating assembly 400, and a snap-fit ​​assembly 500. The protective lens 100 is provided with a buckle 110; the base 200 is provided with a locking groove 210 and an unlocking groove 220, which are connected; the cover plate 300 is an open-shaped shell, with a clearance groove 310 on its side wall, and is rotatably connected to the base 200, with the opening of the cover plate 300 facing the base 200; the rotating assembly 400 includes a rotating handle 410, with a locking pin 411 on the rotating handle 410, and the rotating assembly 400 is movably mounted on the cover plate 300. The opening end of the cover plate 300 is engaged with the cover plate 300 in a transmission cooperation. The locking pin 411 is slidably disposed in the locking groove 210 or the unlocking groove 220, and the rotation center of the cover plate 300 is offset from the center line of the rotating assembly 400. The snap-fit ​​assembly 500 includes an elastic element 510 and a snap-fit ​​element 520. The snap-fit ​​element 520 is connected to the elastic element 510. The elastic element 510 is limited and connected to the rotating assembly 400 and is located between the rotating assembly 400 and the cover plate 300. The snap-fit ​​element 520 can extend or retract into the cover plate 300 through the clearance groove 310.

[0043] When the locking pin 411 is in the locking groove 210, the snap-fit ​​520 extends out of the cover plate 300 and snaps into the buckle 110. When the rotating handle 410 is turned so that the locking pin 411 is in the unlocking groove 220, the snap-fit ​​520 disengages from the buckle 110 and retracts into the cover plate 300.

[0044] Because a locking component 500 is provided that can engage with the unlocking slot 220, the locking component 500 is located between the rotating component 400 and the cover plate 300 and is limitedly connected to the rotating component 400; and the rotating component 400 is movably located on the cover plate 300 and is in transmission cooperation with the cover plate 300, and the rotation center of the cover plate 300 is offset from the center line of the rotating component 400. Therefore, when it is necessary to remove the goggle lens 100, turn the rotating handle 410 to make the locking pin 411 in the locking groove 210 slide into the unlocking groove 220; at this time, the rotating component 400 rotates around its own center line in the first direction, and drives the cover plate 300 to rotate around its rotation center in the first direction; during this process, since the rotating component 400 and the cover plate 300 rotate simultaneously and their rotation centers are different, the elastic element 510 in the snap-fit ​​component 500 is compressed by the rotating component 400 and the cover plate 300, and the snap-fit ​​element 520 connected to the elastic element 510 disengages from the buckle 110 and retracts into the cover plate 300, so that the goggle lens 100 is disengaged from the snap-fit ​​component 500, thereby realizing the disassembly of the goggle lens 100, which facilitates the subsequent maintenance or replacement of the goggle lens 100. When the protective lens 100 needs to be installed, place the buckle 110 on the protective lens 100 on the base 200, and then turn the rotating handle 410 to make the locking pin 411 in the unlocking groove 220 slide into the locking groove 210; at this time, the rotating component 400 rotates around its own center line in a second direction opposite to the first direction, and drives the cover plate 300 to rotate around its rotation center in a second direction opposite to the first direction; during this process, the rotating component 400 and the cover plate 300 gradually release the compression of the elastic element 510 in the snap-fit ​​component 500, and the elastic element 510 rebounds on its own, so that the snap-fit ​​element 520 connected to the elastic element 510 extends out of the cover plate 300, and at the same time press the protective lens 100 to make the buckle 110 snap into the snap-fit ​​element 520, so as to realize the installation of the protective lens 100. Throughout the process, the goggle lens 100 can be disassembled simply by turning the handle 410. The disassembly process is simple and easy to operate, facilitating the replacement or maintenance of the goggle lens 100. At the same time, by turning the handle 410, difficulties in disassembly and assembly due to interference with the goggle lens 100 or helmet can be avoided. In addition, in this embodiment, to further improve the connection strength and disassembly convenience of the goggle lens 100, a mounting ring is provided on the goggle lens 100, and the buckle 110 is provided on the mounting ring.

[0045] In some embodiments, the base 200 is further provided with a buffer groove 230, and a locking groove 210 and an unlocking groove 220 are located on both sides of the buffer groove 230 and are both connected to the buffer groove 230. When the rotating handle 410 is turned so that the locking pin 411 is in the buffer groove 230, the connection strength between the latch 520 and the buckle 110 is weakened, but not completely disengaged. Therefore, a groove buffer is provided between the locking groove 210 and the unlocking groove 220 to prevent the locking pin 411 from sliding directly from the locking groove 210 to the unlocking groove 220 due to accidental activation of the rotating handle 410, which could cause the goggle 100 to disengage from the latch 520, thus improving the safety of the helmet. In addition, to ensure the effectiveness of the buffer groove 230, the buffer groove 230 is located below the locking groove 210 and the unlocking groove 220.

[0046] In some embodiments, a plurality of positioning grooves 240 are provided on the left side wall of the base 200, and the plurality of positioning grooves 240 are spaced apart along the extending direction of the left side wall. A positioning post 120 is provided on the goggle 100, and the positioning post 120 engages with the positioning groove 240. The side walls of adjacent positioning grooves 240 are smoothly connected. By engaging the positioning post 120 with the positioning groove 240 at different positions, the goggle 100 can be held in the corresponding position, thereby avoiding the sudden drop of the goggle 100 due to bumps or other issues during helmet use, thus further improving the safety of helmet use.

[0047] In some embodiments, the cover plate 300 is provided with a rotating column and an auxiliary component 330; the rotating column is provided on one side of the cover plate 300 and is rotatably connected to the rotating groove 250 in the base 200, and the rotating groove 250 is provided on the upper side of the unlocking groove 220; the auxiliary component 330 is provided at the open end of the cover plate 300, the auxiliary component 330 is slidably engaged with the guide limiting groove 260 in the base 200, and is in a transmission engagement with the rotating assembly 400.

[0048] In this embodiment, the cover plate 300 has a circular cross-section. A rotating part 320 is provided on one side of the cover plate 300. A rotating column is provided in the rotating part 320 and extends towards the opening end of the cover plate 300. The rotating groove 250 is provided at the upper right of the unlocking groove 220. When the rotating component 400 rotates around its own centerline in the first direction and drives the cover plate 300 to rotate around its rotating column in the first direction, the compression effect on the elastic element 510 is ensured, and interference between the rotating component 400 and the cover plate 300 is avoided. At the same time, the rotating column of the cover plate 300 and the centerline of the rotating component 400 are misaligned. The guide limiting groove 260 is an arc-shaped groove centered on the rotating column. When the rotating handle 410 is turned to rotate the cover plate 300, the auxiliary component 330 cooperates with the guide limiting groove 260 to ensure that the cover plate 300 always rotates along the extension direction of the guide limiting groove 260. When the cover plate 300 returns to its original position, the auxiliary component 330 abuts against the section of the guide limiting groove 260 near the rotating column to prevent the cover plate 300 from over-rotating in the second direction, which would affect the overall performance. In addition, the base 200 is also provided with a second guide groove 270, which is opposite to the guide limiting groove 260 and extends towards the guide limiting groove 260. A corresponding guide connector is provided on the cover plate 300, which slides with the second guide groove 270 to ensure the rotation path and rotation effect of the cover plate 300 when the rotating handle 410 is turned.

[0049] In some embodiments, two snap-fit ​​members 520 are provided, and correspondingly, two clearance slots 310 are provided. The two snap-fit ​​members 520 are spaced apart in the left-right direction, and the elastic member 510 is provided between the two snap-fit ​​members 520.

[0050] For example, as shown in Figures 2 to 5, the two clearance grooves 310 are arranged at relative intervals in the left-right direction, and the corresponding goggle lens 100 is provided with two buckles 110. When the locking pin 411 is located in the locking groove 210, the two snap-fit ​​pieces 520 extend out of the cover plate 300 through the corresponding clearance grooves 310 and snap-fit ​​with the corresponding buckles 110 to improve the connection strength and installation stability of the goggle lens 100.

[0051] In some embodiments, the elastic member 510 is plate-shaped, and two limiting groove groups are provided on the elastic member 510. A guide protrusion is formed at the connection between the snap-fit ​​member 520 and the elastic member 510. The two limiting groove groups are spaced apart in the left-right direction. Both limiting groove groups are provided on the end face of the elastic member 510 near the rotating component 400, and are limited and cooperated with the corresponding limiting pin 421 on the rotating component 400. The position of the limiting pin 421 in the limiting groove group is changed so that the elastic member 510 is in a compressed or retracted state. The guide protrusion is guided and cooperated with the corresponding first guide groove on the cover plate 300.

[0052] For example, referring to Figure 5, in this embodiment, the elastic member 510 is plate-shaped with an annular cross-sectional shape. Specifically, it includes two elastic portions 513 and two connecting portions 514. The two elastic portions 513 are spaced apart in the vertical direction, and the two connecting portions 514 are spaced apart in the horizontal direction between the two elastic portions 513. Two snap-fit ​​members 520 are correspondingly arranged on opposite sides of the two connecting portions 514. A guide protrusion is formed at the connection between the snap-fit ​​members 520 and the corresponding snap-fit ​​member 520, and the guide protrusion guides and cooperates with the corresponding first guide groove. The elastic portion 513 is a compression elastic portion 513. A set of limiting grooves is provided on the end face of the connecting portion 514 near the rotating assembly 400, and the set of limiting grooves on the two connecting portions 514 is symmetrical about the midpoint of the elastic member 510.

[0053] Taking the limiting groove group set on the right connecting part 514 as an example. The specific structure of the limiting groove group is as follows: from top to bottom, a first limiting guide groove 5121, a second limiting guide groove 5122, a third limiting guide groove 5123, and a fourth limiting guide groove 5124 are arranged sequentially, and the opening of each limiting guide groove faces to the right; the depth of the first limiting guide groove 5121 is less than the depth of the second limiting guide groove 5122, and a first limiting segment 5125 is provided on the side wall of the second limiting guide groove 5122 away from the first limiting guide groove 5121, and the first The limiting segment 5125 is positioned near the opening of the second limiting guide groove 5122. The depth of the second limiting guide groove 5122 is greater than the depth of the third limiting guide groove 5123, and the depth of the third limiting guide groove 5123 is less than the depth of the fourth limiting guide groove 5124. A second limiting segment 5126 is provided on the side wall of the fourth limiting guide groove 5124 away from the third limiting guide groove 5123, and the second limiting segment 5126 is positioned near the opening of the fourth limiting guide groove 5124. Two limiting pins 421 are provided on the rotating assembly 400 corresponding to the limiting groove group on the right side. The side of both limiting pins 421 near the center of the rotating assembly 400 is provided as a guide sliding part, which is an arc-shaped surface to improve the convenience and tightness of the limiting pins 421 when engaging with the limiting groove group. The side away from the center of the rotating assembly 400 is provided as a limiting abutment part. When the locking pin 411 is located in the unlocking groove 220, the two limiting pins 421 are respectively limited and engaged with the first limiting guide groove 5121 and the third limiting guide groove 5123. Since the first limiting guide groove 5121 and the third limiting guide groove 5123 are small, the pressure on the elastic member 510 increases, thereby compressing the elastic part 513 and driving the connecting part 514 and the snap fastener 520 to retract, realizing the disengagement of the snap fastener 520 from the buckle 110, so as to complete the disassembly of the goggle lens 100. When the locking pin 411 is located in the locking groove 210, the two limiting pins 421 are respectively engaged with the second limiting guide groove 5122 and the fourth limiting guide groove 5124. Since the second limiting guide groove 5122 and the fourth limiting guide groove 5124 are relatively deep, the pressure on the elastic member 510 can be released. After the elastic part 513 is no longer under force, it rebounds on its own, thereby driving the two connecting parts 514 to move away from each other. This allows the snap-fit ​​member 520 to extend from the corresponding clearance groove 310 and snap-fit ​​with the corresponding buckle 110, thereby completing the installation of the goggle lens 100. Furthermore, the limiting abutment parts of the two limiting pins 421 abut with the first limiting section 5125 and the second limiting section 5126 respectively, preventing the elastic member 510 from disengaging from the rotating component 400 due to the large rotation amplitude of the rotating component 400. Throughout the process, the guide protrusion and the corresponding first guide groove guide and cooperate to limit the relative position of the snap-fit ​​component 500 within the cover plate 300. At the same time, it ensures that the elastic element 510 is compressed or rebounds autonomously as the cover plate 300 and the rotating component 400 rotate, thereby ensuring the overall performance of the goggle mechanism.

[0054] In some embodiments, the rotating assembly 400 further includes a rotating switch 420, a limiting pin 421 disposed on the end face of the rotating switch 420 near the elastic member 510, and the rotating switch 420 connected to the rotating handle 410. By turning the rotating handle 410, the application effect of the rotating switch 420 can be achieved, and since the rotating switch 420 and the rotating handle 410 are separately configured, the assembly difficulty of the goggle mechanism can be reduced.

[0055] In some embodiments, the rotary switch 420 is further provided with an abutment member 422. The abutment member 422 is disposed opposite to the rotary handle 410 on the upper side of the rotary switch 420 and extends towards the cover plate 300. The abutment member 422 abuts against the auxiliary member 330 to ensure the transmission effect with the cover plate 300. Specifically, when the rotary handle 410 is turned from the locking groove 210 to the unlocking groove 220, the rotary switch 420 rotates in the first direction, and the abutment member 422 abuts against the auxiliary member 330 to drive the cover plate 300 to rotate around the rotating column in the first direction, thereby ensuring the compression effect on the elastic member 510 to ensure that the snap-fit ​​member 520 retracts smoothly.

[0056] After the goggle lens 100 is removed, to ensure that the cover plate 300 and the rotary switch 420 can return to their original positions for the next installation of the goggle lens 100, the goggle mechanism also includes a first reset member 600 and a second reset member 700. Specifically, the first reset member 600 is disposed between the auxiliary member 330 and the base 200. The first reset member 600 is configured as a compression spring. When the rotary switch 420 cooperates with the cover plate 300 to compress the elastic member 510, the first reset member 600 is compressed synchronously. When the rotary switch 420 releases the compression of the first reset member 600 from the cover plate 300, the first reset member 600 rebounds autonomously, thereby pushing the auxiliary member 330 to rotate around the rotating column in the second direction, so that the cover plate 300 returns to its original position. The second reset member 700 is disposed between the abutment member 422 and the cover plate 300. The second reset member 700 is configured as a tension spring. When the rotary switch 420 cooperates with the cover plate 300 to compress the elastic member 510, the second reset member 700 is stretched synchronously. When the rotary switch 420 and the cover plate 300 release the tension on the first reset member 600, the second reset member 700 retracts autonomously. During the process of the cover plate 300 returning to its original position, it drives the rotary switch 420 to rotate in the second direction, so that the rotary switch 420 and the cover plate 300 return to their original positions at the same time.

[0057] In some embodiments, the end face of the abutment member 422 near the cover plate 300 is configured as a first guide surface 4221, and the goggle lens 100 is provided with a second guide surface 130 that guides and cooperates with the first guide surface 4221.

[0058] As shown in Figures 2 and 7, the end face of the mounting ring facing away from the goggle lens 100 is provided with a clearance surface and an abutment surface. The second guide surface 130 is disposed between the clearance surface and the abutment surface. When the goggle lens 100 is installed on the helmet, the abutment member 422 is disposed opposite to the clearance surface. Along the first direction, the first guide surface 4221 is inclined towards the direction of the rotary switch 420, and the second guide surface 130 is inclined away from the direction of the rotary switch 420. When the rotary handle 410 is turned, causing the rotary switch 420 to rotate around its own centerline along the first direction, the first guide surface 4221 and the second guide surface 130 guide and cooperate. When the locking pin 411 is located behind the unlocking groove 220, the snap-fit ​​member 520 disengages from the buckle 110. At the same time, the abutment member 422 abuts against the abutment surface, and the abutment member 422 pushes out the goggle lens 100, further improving the convenience of removing the goggle lens 100.
