Description

Technical Field

[0001] This utility model relates to the field of safety helmet technology, and in particular to a helmet ventilation structure and a helmet. Background Technology

[0002] Cycling helmets not only protect the head from accidental injuries while riding, but also improve comfort to a certain extent. Motorcycle helmets, in particular, can become uncomfortable and stuffy when worn for extended periods, affecting the wearer's performance and posing a safety hazard. Therefore, ventilation structures are necessary to enhance comfort.

[0003] Existing helmet ventilation structures all require adjusting the air intake by changing the opening degree of the sliding cover. However, since the air intake is affected by the riding speed during motorcycle riding, users need to frequently adjust the opening degree of the sliding cover, which distracts their attention and poses a safety hazard. Utility Model Content

[0004] The purpose of this invention is to provide a helmet ventilation structure and helmet that can automatically adjust the air intake according to vehicle speed.

[0005] To achieve this objective, the present invention adopts the following technical solution:

[0006] Helmet ventilation structure, including:

[0007] Mounting bracket, installed on the helmet shell;

[0008] The push plate includes a push plate body and a wind deflector. The push plate body is adjustablely mounted on the mounting base. The wind deflector is fixedly connected to the side of the push plate body facing the helmet shell, and the wind deflector is set at an angle to the push plate body.

[0009] An air guide assembly includes an elastic air guide plate, one end of which is a fixed end and the other end is a movable end. The fixed end is fixedly mounted on the helmet shell, and the movable end extends obliquely into the outer air inlet of the helmet shell. The outer air inlet is located on the top front side of the helmet shell.

[0010] The push plate has an open state and a closed state. When the push plate is in the closed state, the wind baffle is blocked above the fixed end. When the push plate is in the open state, the wind baffle is positioned above the movable end, allowing airflow to enter the external air inlet along the elastic air guide plate.

[0011] Preferably, the air guide assembly further includes:

[0012] The mounting base is fixedly connected to the helmet shell;

[0013] The elastic support member has one end fixedly connected to the fixed base and the other end supported on the side of the movable end near the external air inlet.

[0014] Preferably, the mounting base includes:

[0015] The base plate is detachably connected to the helmet shell;

[0016] The top plate is slidably connected to the top of the bottom plate. One end of the top plate is connected to the helmet shell, and the other end is provided with a bend. The windshield can abut against the bend.

[0017] Preferably, the top plate is provided with a buckle at one end connected to the helmet shell, and the helmet shell has an installation opening, into which the buckle can be engaged.

[0018] Preferably, a baffle is provided on the outer periphery of the upper surface of the top plate, and the baffle can abut against the push plate.

[0019] Preferably, when the push plate is in the open state, the height of the stop bar is higher than the height of the edge of the push plate.

[0020] Preferably, the mounting base has a limiting groove, and the bottom surface of the push plate body has a protruding mounting rod, one end of which can extend into the limiting groove.

[0021] Preferably, the bottom of the limiting groove is provided with a locking groove, and when the push plate is in the closed state, the mounting rod can extend into the locking groove and fit against the inner wall of the locking groove.

[0022] Helmets, including:

[0023] The helmet shell has an external air intake;

[0024] The aforementioned helmet ventilation structure.

[0025] Preferably, the helmet also includes a cushioning liner, which is nested inside the helmet shell. The cushioning liner has an inner air inlet, which is connected to the outer air inlet. The elastic air guide plate is located outside the inner air inlet.

[0026] The beneficial effects of this utility model are:

[0027] When users need ventilation while riding, they can push the baffle from the closed state to the open state with one hand, so that the baffle moves above the movable end of the flexible air guide plate, allowing airflow to enter the external air intake along the flexible air guide plate. As the vehicle speed increases, the wind load applied to the flexible air guide plate increases, so the air intake volume increases with the increase of the distance between the flexible air guide plate and the air guide plate, thus realizing the automatic adjustment of the air intake volume with the vehicle speed.

[0040] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0041] like Figures 1-3 As shown, this utility model provides a helmet ventilation structure for ventilation during cycling. The helmet ventilation structure includes a mounting base 1, a push plate 2, and an air guide assembly 3. Mounting base 1 is mounted on helmet shell 100; push plate 2 includes push plate body 21 and wind deflector 22. Push plate body 21 is adjustablely mounted on mounting base 1. Wind deflector 22 is fixedly connected to the side of push plate body 21 facing helmet shell 100, and wind deflector 22 is angled to push plate body 21; air guide assembly 3 includes elastic air guide plate 31. One end of elastic air guide plate 31 is fixed end 311, and the other end is movable end 312. Fixed end 311 is fixedly mounted on helmet shell 100. Movable end 312 extends obliquely into external air inlet 101 of helmet shell 100. External air inlet 101 is located on the top front side of helmet shell 100; push plate 2 has an open state and a closed state. When in the closed state, wind deflector 22 blocks the top of fixed end 311. When in the open state, wind deflector 22 avoids the top of movable end 312, so that airflow can enter external air inlet 101 along elastic air guide plate 31.

[0042] When users need ventilation while riding, they can adjust the push plate 2 from the closed state to the open state with one hand, so that the wind deflector 22 moves above the movable end 312 of the elastic air guide plate 31, allowing airflow to enter the external air inlet 101 along the elastic air guide plate 31. As the vehicle speed increases, the wind load applied to the elastic air guide plate 31 increases, so the air intake increases with the increase of the distance between the elastic air guide plate 31 and the wind deflector 22, which can realize the automatic adjustment of the air intake with the vehicle speed.

[0043] Specifically, the air guide assembly 3 also includes a fixed base 32 and an elastic support 33. The fixed base 32 is fixedly connected to the helmet shell 100; one end of the elastic support 33 is fixedly connected to the fixed base 32, and the other end is supported on the side of the movable end 312 near the external air inlet 101. With this configuration, the elastic support 33 can support the elastic air guide plate 31 through its own elastic restoring force, preventing the deformation of the elastic air guide plate 31 from exceeding its elastic limit due to excessive wind pressure, thus preventing damage to the elastic air guide plate 31.

[0044] In this embodiment, both the elastic air guide plate 31 and the elastic support member 33 are commonly used elastic metal materials in the art, and both can provide elastic restoring force in their own thickness direction.

[0045] Specifically, the mounting base 1 includes a base plate 11 and a top plate 12. The base plate 11 is detachably connected to the helmet shell 100; the top plate 12 is slidably connected to the top of the base plate 11, with one end connected to the helmet shell 100 and the other end having a bend 120 against which the wind deflector 22 can abut. With this configuration and the bend 120, the wind deflector 22 can conform to the bend 120. During riding, when the push plate 2 is in the open state, no airflow enters between the wind deflector 22 and the bend 120, thus preventing the wind deflector 22 from vibrating under the influence of airflow.

[0046] Specifically, a buckle 121 is provided at one end of the top plate 12 that connects to the helmet shell 100. The helmet shell 100 has an installation opening, into which the buckle 121 can be engaged. The buckle 121 eliminates the need for bolts or pins to connect the top plate 12 to the helmet shell 100, ensuring connection strength while improving user safety in the event of an accident.

[0047] More specifically, a baffle 122 is provided on the outer periphery of the upper surface of the top plate 12, and the push plate 2 can abut against the baffle 122. With the above arrangement, the push plate 2 can transfer the wind load to the top plate 12 through contact with the baffle 122, thereby improving the stability of the push plate 2.

[0048] More specifically, when the push plate 2 is in the open state, the height of the baffle 122 is higher than the height of the edge of the push plate 2. This arrangement prevents wind from entering the interior of the helmet shell 100 through the gap between the top plate 12 and the push plate 2 during the user's riding, thus improving the seal.

[0049] Specifically, a limiting groove 10 is provided on the mounting base 1, and a mounting rod is protruding from the bottom surface of the push plate body 21, one end of which can extend into the limiting groove 10. With the above configuration, the limiting groove 10 is provided on the top plate 12, and the mounting rod and the limiting groove 10 cooperate with each other to prevent the push plate body 21 from separating from the top plate 12 during the user's riding.

[0050] More specifically, the bottom of the limiting groove 10 is provided with a locking groove 101a. When the push plate 2 is in the closed state, the mounting rod can extend into the locking groove 101a and fit against the inner wall of the locking groove 101a. With the locking groove 101a provided, when it is necessary to move the push plate 2 from the closed state to the open state, first lift the push plate body 21 to separate the mounting rod from the locking groove 101a, and then push the push plate body 21 horizontally. The operation is simple and convenient.

[0051] This utility model also provides a helmet for motorcycle riding. The helmet includes a helmet shell 100 and the aforementioned helmet ventilation structure. The helmet shell 100 has an external air inlet 101. It is understood that this helmet possesses all the beneficial effects of the aforementioned helmet ventilation structure, which will not be elaborated upon here.

[0052] Specifically, the helmet also includes a cushioning liner 200, nested inside the helmet shell 100. The cushioning liner 200 has an inner air inlet 201, which is connected to the outer air inlet 101. An elastic air guide plate 31 is located outside the inner air inlet 201. The aforementioned cushioning liner 200 enhances the protection of the user's head.

[0053] For example, in this embodiment, the material of the cushioning liner 200 includes, but is not limited to, expanded polystyrene (EPS), which has a low relative density (1.05 g / cm³). 3 It has advantages such as low thermal conductivity, low water absorption, resistance to impact and vibration, heat insulation, sound insulation, moisture resistance, vibration damping, and excellent dielectric properties. In other embodiments, the buffer liner 200 may also use other materials commonly used in the art, and no specific limitation is made here.

[0054] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
