Description

Technical Field

[0001] This application belongs to the technical field of helmets, and in particular, relates to a shutter structure for helmets. Background Art

[0002] Helmets are generally divided into half helmets and full helmets. In order not to affect the user's auditory effect during wearing, full helmets usually need to be designed with sound holes to meet the requirements. At present, most helmets can only meet the sound passing requirements and cannot meet the function of both passing sound and waterproofing. During testing, the waterproof effect of the helmet is poor, resulting in the test head mold being easily colored, which does not meet the requirement of the GA294 standard that "riot helmets should be able to withstand the spraying of test liquids, and the test head mold should not be colored". Summary of the Invention

[0003] This application provides a shutter structure for helmets, which solves the problem that helmets can only meet the sound passing requirements and cannot meet the requirements of both passing sound and waterproofing.

[0004] An embodiment of this application provides a shutter structure for helmets, including a helmet sound passing shell arranged on the helmet. The helmet sound passing shell is provided with a shutter, the helmet sound passing shell is provided with mounting holes and sound holes, the shutter is provided with a sound channel, and a drainage port is arranged at the lower part of the shutter.

[0005] In one embodiment,

[0006] The helmet sound passing shell is recessed towards the inside of the helmet, and the formed recessed area is used for mounting the shutter.

[0007] In one embodiment,

[0008] The number of the mounting holes and the sound holes is at least one. Preferably, the number of the mounting holes is four, and the number of the sound holes is three.

[0009] In one embodiment,

[0010] On the outer side of the helmet, water blocking bosses are arranged on both the mounting holes and the sound holes.

[0011] In one embodiment,

[0012] The shutter is composed of slats, and the slats include top slats, middle slats and bottom slats.

[0013] In one embodiment,

[0014] The number of the slats is at least one. Preferably, the number of the slats is four.

[0015] In one embodiment,

[0016] Both the top plate strip and the middle plate strip are provided with hollow parts in the middle, and the gaps between adjacent two plate strips form sound channels.

[0017] In one embodiment,

[0018] Mounting posts are provided at the rear side of the plate strip, and the number of the mounting posts is at least one. Preferably, the number of the mounting posts is four.

[0019] In one embodiment,

[0020] All the plate strips are inclined towards the outside of the helmet, and a plurality of the plate strips are arranged in a stepped inclination.

[0021] In one embodiment,

[0022] The number of the helmet sound-permeable shells and the louvers is at least one.

[0023] The present application provides a louver structure for a helmet, and the structural combination of the louver and the helmet sound-permeable shell. Even if water enters from the gaps of the louver, it will not enter the interior of the helmet, but is discharged from the drainage ports of the louver. Moreover, water-blocking bosses are arranged at the sound-permeable holes and mounting holes, so that water will not flow into the interior of the helmet, realizing the waterproof function. The cooperation between the sound-permeable holes of the louver and the sound channels of the helmet sound-permeable shell can make sound more easily transmitted into the interior of the helmet, achieving the sound-permeable effect, thereby realizing the functions of sound permeability and waterproofing of the helmet. The louver structure for a helmet provided by the present application has a wide application range and can be applied to full-face helmets with various different shapes and working environments. And it is convenient to install, without considering the sealing problem between the louver and the helmet sound-permeable shell, allowing liquid to enter the gaps between the louver and the helmet sound-permeable shell, and it can be discharged through the drainage ports, easily solving the water leakage problem.

[0032] In order to make the technical problems, technical solutions and beneficial effects to be solved by this application clearer and more understandable, this application is further described in detail. It should be understood that the specific embodiments described herein are only used to explain this application and are not used to limit this application.

[0033] In one of the embodiments, a shutter structure for a helmet is as Figures 1 - 3 shown, including a helmet sound - conducting shell 1 provided on a helmet 6. A shutter 2 is provided on the helmet sound - conducting shell 1. The helmet sound - conducting shell 1 is recessed towards the inside of the helmet 6 as a whole, and the formed recessed area is used to install the shutter 2. The helmet sound - conducting shell 1 is provided with mounting holes 3 and sound - conducting holes 4. The number of mounting holes 3 and sound - conducting holes 4 is at least one. In this embodiment, the number of mounting holes 3 is four, and the number of sound - conducting holes 4 is three. On one side of the helmet sound - conducting shell 1 on the outer side of the helmet 6, water - blocking bosses 5 are provided on both the mounting holes 3 and the sound - conducting holes 4. The shutter 2 is composed of slats 10. The number of slats 10 is at least one. In this embodiment, the number of slats 10 is four. As Figures 4 - 5 shown, the slats 10 include one top slat 101, two middle slats 102, and one bottom slat 103. Hollowed - out parts 11 are opened in the middle of the top slat 101 and the middle slats 102. The gaps between adjacent two slats 10 form a sound - conducting channel 7. Mounting posts 9 are provided at the rear side of the slats 10. The number of mounting posts 9 is at least one. In this embodiment, the number of mounting posts 9 is four, which are matched with the mounting holes 3. Two of the mounting posts 9 are provided on one of the middle slats 102, and the other two mounting posts 9 are provided on the bottom slat 103. A drainage opening 8 is provided at the lower part of the shutter 2. The number of the helmet sound - conducting shell 1 and the shutter 2 is at least one. In this embodiment, the number of the helmet sound - conducting shell 1 and the shutter 2 is two.

[0034] Specifically, the shapes of the helmet sound - passing shell 1 and the shutter 2 are both rectangles with rounded corners, and the angles of the two upper - side corners are greater than those of the two lower - side corners. The shutter 2 can fit integrally with the helmet sound - passing shell 1. The helmet sound - passing shell 1 is used to fix the shutter 2, and the shutter 2 plays the roles of waterproofing and sound - passing; the mounting post 9 is cylindrical, and its diameter fits that of the mounting hole 3 so that the mounting post 9 can be inserted into the mounting hole 3, thereby mounting the shutter 2 on the helmet sound - passing shell 1; the sound - passing hole 4 needs to be set at a position facing the rear side of the slat 10, avoiding being installed at the rear side of the sound - channel 7, so as to prevent water from splashing directly into the helmet 6 from the sound - channel 7. The water - blocking boss 5 can also prevent water from flowing into the helmet 6 through the mounting hole 3 and the sound - passing hole 4; the gap of the sound - channel 7 is less than 1 mm, the hollowed - out part 11 forms a triangular area, the sound - channel 7 is located at one corner of the triangular area, and the length of the sound - channel 7 is the same as that of the hollowed - out part 11. The sound - passing hole 4, the hollowed - out part 11 and the sound - channel 7 cooperate to facilitate the entry of external sounds into the helmet 6, enabling the user to perceive the road conditions; the drain port 8 is a groove, and the drainage volume of the drain port 8 is greater than the sum of the water inflow volumes of the shutter, ensuring that the water entering between the shutter and the helmet shell will not cause the liquid level to rise due to drainage volume problems; the top slat 101 is C - shaped, the middle slat 102 is L - shaped, and the bottom slat 103 is linear. All four slats 10 are inclined towards the outside of the helmet 6, forming a certain slope and arranged in a stepped and inclined manner. In this way, the rainwater dripping on the shutter will flow out along the slope and will not enter the helmet 6; two helmet sound - passing shells 1 and two shutters 2 are respectively arranged on both sides of the helmet 6.

[0035] This application provides a shutter structure for a helmet, including a helmet sound - passing shell arranged on the helmet. There are shutters on the helmet sound - passing shell, mounting holes and sound - passing holes on the helmet sound - passing shell, a sound - channel on the shutter, and a drain port at the lower part of the shutter; the structural combination of the shutter and the helmet sound - passing shell ensures that even if water enters through the shutter gap, it will not enter the helmet interior but will be discharged from the drain port of the shutter. Moreover, water - blocking bosses are provided at the sound - passing holes and mounting holes, preventing water from flowing into the helmet interior and achieving the waterproof function; the cooperation between the sound - passing holes of the shutter and the sound - channels of the helmet sound - passing shell allows sound to be more easily transmitted into the helmet interior, achieving the sound - passing effect, thereby realizing the functions of both sound - passing and waterproofing for the helmet; the shutter structure for a helmet provided by this application has a wide range of applications and can be applied to full - face helmets with various different shapes and operating environments; and it is easy to install. There is no need to consider the sealing problem between the shutter and the helmet sound - passing shell. It allows liquid to enter the gap between the shutter and the helmet sound - passing shell, and can be discharged through the drain port, easily solving the problem of water leakage.
