Description

Technical Field

[0001] This utility model relates to the field of helmet technology, specifically to a motorcycle helmet with a split-type detachable ventilation valve assembly. Background Technology

[0002] Current motorcycle helmet ventilation systems generally adopt an integrated structure, with the ventilation channel formed integrally with the helmet body. For example, the ventilation structure disclosed in utility model patent CN202323107264.0 for a motorcycle helmet, while achieving ventilation by setting an air inlet at the front of the helmet, an air outlet at the rear, and a ventilation channel inside the helmet, with the air inlet and outlet connected through the channel, and an exhaust port on the inner wall of the helmet connected to the ventilation channel, has a significant hygiene defect: after prolonged use in a riding environment, moisture, dust, and oil secretions from the body will form a mixed deposit in the ventilation channel. However, this integrated ventilation structure cannot be disassembled, and users can only clean the surface with tools such as cotton swabs and brushes, unable to thoroughly clean the internal channels, leading to a significant increase in the risk of bacterial residue. Utility Model Content

[0003] In order to overcome the shortcomings of the existing technology, this utility model provides a motorcycle helmet with a split-type detachable ventilation valve assembly.

[0004] The technical solution adopted by this utility model to solve its technical problem is:

[0005] A motorcycle helmet with a detachable ventilation valve assembly includes a helmet body with a mounting position. The ventilation valve assembly includes a ventilation valve mounted on the mounting position, which is connected to a mounting hole in the mounting position via a detachable component. The detachable component includes a pin on the ventilation valve and a pin movably inserted into the pin. The pin has a hole extending inward from its end face in the middle, and two outwardly extending rods on either side of the hole on the end face of the pin. The outer curvature of the two rods is consistent with the outer curvature of the pin, and one of the rods has a hook structure on its outer side. During installation, the pin is inserted into the mounting hole and extends into the inside of the helmet body. After passing through, the hook structure locks in place inside the mounting hole, forming a limit. The pin passes through the gap between the two rods from the inside of the helmet body and inserts into the hole. The middle part of the pin engages between the two rods to secure the pin in the mounting hole. During disassembly, the pin is removed and the rod is moved to allow the hook to enter the mounting hole, allowing the ventilation valve to be removed.

[0006] Furthermore, the diameter of the head of the pin is larger than the diameter of the middle part, forming a flat brim structure.

[0007] In this invention, the ventilation valve includes a front ventilation valve and a top ventilation valve. The front and top of the helmet body are respectively provided with a front mounting position and a top mounting position. The front ventilation valve is installed in the front mounting position, and the top ventilation valve is installed in the top mounting position. In the detachable component corresponding to the top ventilation valve, the insertion hole extends to penetrate the top ventilation valve. The pin is inserted into the insertion hole from the outside of the top ventilation valve, and the end of the pin is engaged between the two insertion rods to secure the insertion post.

[0008] Furthermore, the ventilation valve includes a valve seat and an adjusting plate. The insert post is disposed on the valve seat, and the valve seat is provided with a sliding groove. A buckle groove is provided in the sliding groove. The rear of the adjusting plate is provided with a corresponding buckle. The adjusting plate is slidably engaged in the buckle groove by the buckle and slides up and down in the sliding groove. The mounting position is provided with an air inlet communicating with the inside of the helmet body. The valve seat is provided with an air inlet communicating with the air inlet. The adjusting plate slides to the upper end to block the air inlet and slides down to gradually open the air inlet.

[0009] Furthermore, the valve seat has a gear slot in the middle of the slide groove, and the adjustment plate has a gear post in the middle of the rear side that cooperates with the gear slot; the gear slot of the front ventilation valve includes three gears connected vertically. When the gear post is in the upper gear slot, the adjustment plate completely covers the air inlet. When it is in the middle gear, the adjustment plate opens 1 / 3 of the air inlet. When it is in the lower gear slot, the adjustment plate fully opens the air inlet.

[0010] Furthermore, the top ventilation valve has a two-stage gear position. When the gear position column slides to the lower gear position position, the adjustment plate blocks the air inlet. When the gear position column slides to the upper gear position position, the adjustment plate opens the air inlet.

[0011] Furthermore, the air intake is provided with a mesh grille.

[0012] This utility model has the following advantages and beneficial effects:

[0013] Featuring a split, detachable ventilation valve assembly, the ventilation valve is connected to the helmet body via a detachable component. When cleaning is needed, users can easily remove the pin and lever to quickly detach the ventilation valve from its mounting position, allowing for a thorough, all-around cleaning of the valve and its internal channels. This effectively removes accumulated dirt and bacteria, ensuring a hygienic environment inside the helmet and providing riders with a healthier and more comfortable experience.

[0026] like Figures 1 to 8As shown, this embodiment discloses a motorcycle helmet with a split-type detachable ventilation valve assembly, including a helmet body 1. The helmet body 1 has mounting positions at the front and top, including a front mounting position 11 and a top mounting position 12. The ventilation valve assembly includes a front ventilation valve 21 mounted on the front mounting position 11 and a top ventilation valve 22 mounted on the top mounting position 12. The rear of the front ventilation valve 21 is also provided with a detachable component, and the front ventilation valve 21 is connected to the mounting hole of the front mounting position 11 via the detachable component. The bottom of the top ventilation valve 22 is also provided with a detachable component, and the top ventilation valve 22 is connected to the mounting hole of the front mounting position 11 via the detachable component. The detachable assembly is connected to the mounting hole in the top mounting position 12. Specifically, the detachable assembly includes an insert post 231 integrally connected to the front ventilation valve 21, and a pin 232 movably inserted into the insert post 231. The insert post 231 has a hole 2310 extending inward from the end face in the middle, and insert rods 2311 extending outward on both sides of the hole 2310 on the end face of the insert post 231. The outer arc of the two insert rods 2311 is consistent with the outer arc of the insert post 231. In addition, one of the insert rods 2311 has a hook structure 2312 on its outer side. During installation, the front ventilation valve 21 is connected to the mounting hole in the top mounting position 12. The insert pin 231 is inserted into the mounting hole and extends into the inner side of the helmet body 1. During insertion, due to the gap between the two insert rods 2311, the locking mechanism 2312 causes the insert rods 2311 to bend elastically, driving the two insert rods 2311 to move closer together, allowing them to pass through the mounting hole. After passing through the mounting hole, the insert rods 2311 elastically return to their original position and are locked inside the mounting hole by the locking mechanism 2312, forming a limit. Finally, the pin 232 is inserted from the inner side of the helmet body 1, through the gap between the two insert rods 2311, and into the insertion hole 2310 to secure the insert pin 231 in the mounting hole. The pin 232 is interference-fitted with the insertion hole 2310. When the pin 232 is inserted into the insertion rod 2311, it can form a certain fastening force. The middle part of the pin 232 fits between the two insertion rods 2311, thereby preventing the insertion rods 2311 from bending elastically and causing the hook to disengage, ensuring the installation stability of the front ventilation valve 21. When disassembling, simply remove the pin 232 and move the insertion rod 2311 to allow the hook to enter the installation hole, and the front ventilation valve 21 can be quickly removed. It is simple and convenient. In addition, in order to facilitate the removal of the pin 232, the diameter of the head of the pin 232 is larger than the diameter of the middle part, forming a flat brim structure.

[0027] In this embodiment, the structure of the detachable component on the front ventilation valve 21 is basically the same as that of the detachable component on the top ventilation valve 22. The difference is that, in the detachable component on the top ventilation valve 22, the insertion hole 2310 extends to both ends until it penetrates the top ventilation valve 22. When the insertion post 231 in the detachable component is inserted into the mounting hole, the pin 232 is inserted into the insertion hole 2310 from the outside of the top ventilation valve 22. After insertion, the end part of the pin 232 engages between the two insertion rods 2311 to secure the insertion post 231, thereby ensuring the installation stability of the top ventilation valve 22.

[0028] In this embodiment, the front ventilation valve 21 includes a valve seat 211 and an adjusting plate 212. The insert post 231 is disposed on the valve seat 211, and the valve seat 211 is fixed in the front mounting position 11. The valve seat 211 is provided with a sliding groove 2111, and the sliding groove 2111 is provided with a snap-fit ​​groove 2112. There are two sets of snap-fit ​​grooves 2112, which are respectively disposed on both sides of the sliding groove 2111. The rear part of the adjusting plate 212 is provided with two corresponding snaps 2121, and the adjusting plate 212 is slidably engaged in the snap-fit ​​groove 2112 by the snaps 2121. After being snapped in place, the adjusting plate 212 slides up and down in the slide groove 2111. In addition, the front mounting position 11 is also provided with an air inlet 100 that connects to the inside of the helmet body 1. The valve seat 211 is provided with an air inlet 2113 that connects to the air inlet 100. When the adjusting plate 212 slides to the upper end, it closes the air inlet 2113. When it slides down, it gradually opens the air inlet 2113. When the air inlet 2113 is opened, the airflow enters from the air inlet 2113, passes through the air inlet 100 and enters the inside of the helmet, and finally flows out from the air outlet on the rear side of the helmet. In addition, the valve seat 211 is provided with a gear slot 2114 in the middle of the slide groove 2111, and the adjustment plate 212 is provided with a gear post 2122 in the middle of the rear side that cooperates with the gear slot 2114. Preferably, the gear slot 2114 includes three gears connected vertically. When the gear post 2122 is in the upper gear slot 2114, the adjustment plate 212 completely covers the air inlet 2113. When it is in the middle gear, the adjustment plate 212 opens 1 / 3 of the air inlet 2113. When it is in the lower gear slot 2114, the adjustment plate 212 fully opens the air inlet 2113.

[0029] Furthermore, to prevent mosquitoes from entering the air inlet 2113 during airflow, a mesh grille is also provided on the air inlet 2113.

[0030] In this embodiment, the structure of the top ventilation valve 22 is basically the same as that of the front ventilation valve 21, both including a valve seat 211 and an adjusting plate 212. The difference is that the gear slot 2114 on the valve seat 211 of the top ventilation valve 22 only includes a second gear. When the gear post 2122 slides to the lower gear slot 2114, the adjusting plate 212 blocks the air inlet. When the gear post 2122 slides to the upper gear slot 2114, the adjusting plate 212 opens the air inlet.

[0031] The above description in this specification is merely an illustrative example of the present invention. Those skilled in the art to which this invention pertains may make various modifications or additions to the specific embodiments described or adopt similar methods to replace them, as long as they do not deviate from the content of this specification or exceed the scope defined in the claims, they shall all fall within the protection scope of this invention.
