Description

Technical Field

[0001] This invention relates to the field of helmets, and in particular to a helmet with an openable and breathable structure. Background Technology

[0002] Helmets are an indispensable tool in our daily transportation, providing excellent protection for people's heads. Helmets offer strong coverage, and to prevent a stuffy feeling during wear, the helmet shell has ventilation holes to maintain breathability and improve safety. However, on rainy days, rainwater can easily enter the helmet through the ventilation holes, causing the head to feel damp and uncomfortable. Additionally, when the outside temperature is low, cold air can also enter the helmet's interior through the ventilation holes, making the head feel cold. Therefore, there is a need to design a helmet with an openable ventilation structure, allowing users to choose whether to open or close the ventilation holes according to their needs. Summary of the Invention

[0003] The purpose of this invention is to provide a helmet with an openable and ventilable structure, which allows people to open and close the vents according to their needs.

[0004] To achieve the above objectives, the solution of the present invention is:

[0005] A helmet with an openable and ventilable structure includes a helmet shell and a ventilable switch assembly. The helmet shell has a front vent and a rear vent on its front and rear sides, respectively. The ventilable switch assembly includes a front cover, a rear cover, and a linkage. The front cover is movably fitted to the front of the helmet shell, and slides to block the front vent, thus controlling its opening and closing. The rear cover is rotatably fitted to the rear of the helmet shell, and rotates to block the rear vent, thus controlling its opening and closing. The linkage connects to the front cover and is hinged to the rear cover. When the front cover moves, it drives the rear cover to rotate via the linkage, so that when the front cover opens the front vent, the rear cover also opens the rear vent, and when the front cover closes the front vent, the rear cover also closes the rear vent.

[0006] The ventilation switch assembly also includes a positioning seat, which is fixed to the front side of the helmet shell and has at least two elastic positioning parts; the front cover has a positioning head that engages with each elastic positioning part of the positioning seat.

[0007] The positioning seat is provided with a positioning port, and each of the elastic positioning parts is provided inside the positioning port.

[0008] The positioning seat has two opposing elastic ribs inside the positioning port, and each elastic positioning part is an elastic opening formed between the two elastic ribs and connected to each other.

[0009] The two elastic ribs inside the positioning opening are wavy.

[0010] The positioning port of the positioning seat is positioned opposite to the front vent.

[0011] The front cover includes an outer front cover plate, an inner front cover plate, and a front cover connecting post connecting the outer front cover plate and the inner front cover plate. The outer front cover plate is located on the outside of the helmet shell, and the inner front cover plate is located on the inside of the helmet shell. The front cover connecting post can move through the front cover vent. The linkage is located on the inside of the helmet shell and is connected to the inner front cover plate of the front cover.

[0012] The inner plate of the front cover is provided with a connector with a connection hole; the linkage is provided with a connecting hook that passes through the connection hole and hooks the connector.

[0013] The helmet shell has a hinge seat fitted inside, and the rear cover is hinged to the hinge seat.

[0014] The inner side of the rear cover is provided with a hinge joint with a hinge hole; the linkage is located inside the helmet shell, and the linkage is provided with a hinge hook that passes through the hinge hole and hooks the hinge joint.

[0015] By adopting the above solution, the ventilation switch assembly of the present invention can open and close the front and rear ventilation ports of the helmet shell, allowing users to open and close them according to their needs, thus meeting their usage requirements in different scenarios. Furthermore, users can control the simultaneous opening or closing of the front and rear ventilation ports by moving the front cover, making the operation of controlling the opening and closing of the front and rear ventilation ports simpler and more convenient. Moreover, since the front and rear ventilation ports of the present invention are located on the front and rear sides of the helmet shell respectively, when both are open simultaneously, air can flow into the helmet shell from the front ventilation port and out from the rear ventilation port, resulting in good airflow and effectively preventing stuffiness when wearing the helmet, thus improving user comfort.

[0033] like Figures 1 to 6 As shown, this invention discloses a helmet with an openable and ventilable structure, comprising a helmet shell 1 and a ventilable switch assembly 2; wherein, the helmet shell 1 has a front vent 11 and a rear vent 12 respectively on its front and rear sides; and the ventilable switch assembly 2 includes a front cover 21, a rear cover 22, and a linkage 23, wherein the front cover 21 is movably fitted to the front side of the helmet shell 1, and the front cover 21 slides to block the front vent 11 to control the opening and closing of the front vent 11, and the rear cover... The rear cover 22 is rotatably fitted to the rear side of the helmet shell 1. The rear cover 22 rotates to block the rear vent 12 and control the opening and closing of the rear vent 12. The linkage 23 connects to the front cover 21 and is hinged to the rear cover 22. When the front cover 21 moves, the front cover 21 drives the rear cover 22 to rotate through the linkage 23, so that when the front cover 21 opens the front vent 11, the rear cover 22 also opens the rear vent 12, and when the front cover 21 closes the front vent 11, the rear cover 22 also closes the rear vent 22.

[0034] In this invention, the ventilation switch assembly 2 can open and close the front ventilation port 11 and the rear ventilation port 12, allowing users to open and close them according to their needs, thus meeting their usage requirements in different scenarios. Furthermore, users can control the simultaneous opening or closing of the front ventilation port 11 and the rear ventilation port 12 by moving the front cover 21, making the operation of opening and closing the front and rear ventilation ports 11 and 12 simpler and more convenient. Moreover, since the front ventilation port 11 and the rear ventilation port 12 are located on the front and rear sides of the helmet shell 1 respectively, when both are open simultaneously, air can flow from the front ventilation port 11 into the helmet shell 1 and then out through the rear ventilation port 12, resulting in good airflow in the helmet and effectively preventing stuffiness when wearing it, thus improving user comfort.

[0035] In this invention, the linkage 23 can be located inside the helmet shell 1 to avoid the linkage 23 being exposed and affecting the integrity of the helmet. At the same time, the helmet shell 1 can protect the linkage 23. The linkage 23 can be formed by a metal rod.

[0036] In this invention, the front cover 21 may include a front cover outer plate 211, a front cover inner plate 212, and a front cover connecting post 213 connecting the front cover outer plate 211 and the front cover inner plate 212.

This invention enables the positioning of the front cover 21 at at least two positions by engaging the positioning heads 2111 with each of the elastic positioning parts 241, so that the front cover 21 can be positioned at the position where the front vent 11 is open or at the position where the front vent 11 is closed. This allows the front cover 21 and the rear cover 22 to stably open the front vent 11 and the rear vent 12, respectively, and to stably close the front vent 11 and the rear vent 12, respectively.

[0039] In this invention, the positioning seat 24 may be provided with a positioning port 242, and each of the elastic positioning parts 241 is provided in the positioning port 242. The positioning port 242 may be arranged opposite to the front vent 11. The positioning port 242 is provided with two opposite elastic ribs 2421. Each elastic positioning part 241 is an elastic opening 2411 formed between the two elastic ribs 2421 and interconnected with each other. The positioning head 2111 is movably engaged with each elastic opening 2411. The two elastic ribs 2421 in the positioning port 242 are wavy, so that each elastic opening 2411 is in the shape of a candied hawthorn, so that the elastic opening 2411 can stably hold the positioning head 2111.

[0040] In this invention, the positioning seat 24 may be provided with a clearance opening 243 corresponding to the front cover connecting post 213 for the front cover connecting post 213 to pass through and move, so as to prevent the positioning seat 24 from causing the front cover 1 to be unable to move.
