Abstract

The utility model relates to a helmet, particularly a helmet with a vented groove, which comprises a housing, a vibration-absorbing layer and an internal lining. An air vent is arranged on the housing, and the internal lining comprises a cap enclosure which is enclosed on the circumference of head and a crown mutually connected with the cap enclosure, which are uniformly adapted to the inner surface of the vibration-absorbing layer. An air channel communicating with the air vent is arranged on the vibration-absorbing layer, and an air passage communicating with the air channel is arranged between the upper edge of the cap enclosure and two side edges of the crown. A vented groove is arranged on the cap enclosure and the inner surface of the crown, and a vented groove is installed in the 360 DEG contact range of the internal lining of the helmet and the head, which can make air flow naturally along the groove, after wind enters into the air vent on the surface of the helmet, the wind rotates around the head, discharged from the bottom, and the flow ventilation of the air between the inner cavity of the helmet and the head is formed, which makes the utility model emit heat and advance the comfort of driver girding the helmet.

Description

The helmet

Technical field

The utility model relates to a kind of helmet, is specifically related to a kind of helmet that has ventilating duct.

Background technology

In order to guarantee motorcycle or racing driver's safety, require the driver must wear the helmet, the helmet of being worn is regardless of season, during the broiling summer, though helmet shell and vibration damping layer are provided with air vent,, excuse helmet liner is the integral planar contact with contacting of head, air vent and liner do not connect, inner helmet atmosphere draught-free, heat are difficult for distributing, and make people's head feel sultry, influence comfortableness, increased the unsafe factor when driving.

The utility model content

The purpose of this utility model is to overcome above-mentioned shortcoming, and a kind of simple in structure, better helmet of ventilation and heat is provided.

In order to achieve the above object, the technical solution of the utility model is: a kind of helmet, comprise shell, vibration damping layer and liner, described shell is provided with ventilating opening, described liner comprises cap defensive wall and the crown interconnective with it that is trapped among on the head circumference, both are all suitable with vibration damping layer inner surface, described vibration damping layer is provided with the air channel that communicates with ventilating opening, be provided with the airway that communicates with described air channel between the upper edge of described cap defensive wall and the dual-side of crown, on described cap defensive wall and the crown inner surface ventilation groove arranged.

The utility model helmet, wherein said ventilating opening are two ventilating openings that left-right symmetry is arranged.

The utility model helmet, the ventilation groove of wherein said cap defensive wall is for vertically being the vertical groove that 0-45 ° of any angle arranged, and the ventilation groove of described crown is pressed fore-and-aft direction and is arranged.

The utility model helmet wherein is provided with a transversal ventilation groove that intersects with described vertical groove at cap defensive wall circumferencial direction.

The utility model helmet, wherein said liner is a three-decker, the surface ground floor is the lining cloth layer, the second layer is the sponge strip layer, its each sponge strip width 2-15mm, thickness 2-15mm, be spaced apart 2-15mm between the adjacent sponge strip, the 3rd layer is spongy layer, and thickness 2-16mm bonds together between each layer mutually.

The utility model helmet, wherein said lining cloth layer are chemical fibre looped fabric or fire-retardant looped fabric, and described sponge strip layer and spongy layer material are foam sponge or flame-retardant sponge.

The utility model helmet, wherein said ventilating opening is equipped with on-off valve in (7).

The utility model advantage is with good effect: in 360 ° of scopes that helmet liner contacts with head the ventilation and heat groove is set, air is flowed naturally along groove, behind the ventilating opening air intake of helmet case surface, can around head, rotate and discharge from the bottom, form the mobile ventilation of air between helmet inner chamber and head, distribute heat improves the comfortableness that the driver wears the helmet well, no matter can both improve ventilation effect from visual sensory and in the practical application.

Adopting fire proofing material to make helmet liner then promptly can ventilation and heat, can also protect the safety of driver's head under accident is caught fire situation, and in sum, this helmet progress and practical function technically is conspicuous.

Below in conjunction with drawings and Examples the utility model is further specified:

Description of drawings

Fig. 2 is a helmet left view of the present utility model;

Fig. 3 is a helmet liner expanded view of the present utility model;

Fig. 4 is the A-A profile of helmet liner among Fig. 1.

The specific embodiment

With embodiment technical scheme is elaborated below.

Reference is as Fig. 1, Fig. 2, Fig. 3, Fig. 4.Fig. 1, the helmet shown in Figure 2, comprise glass fibre reinforced plastics casing 1, EPS vibration damping layer 2 and liner 3 be housed successively in it, liner 3 is a three-decker as shown in Figure 4, surface ground floor lining cloth layer 10, material is the chemical fibre looped fabric, the second layer is a sponge strip layer 11, and its each sponge strip width 15mm also can select between 2-15mm, thickness is 2mm, also can select between 2-15mm, the interval 5mm between the adjacent sponge strip also can select between 2-15mm, material is a foam sponge, the 3rd layer is spongy layer (12), and thickness 2mm also can select between 2-15mm.Bond together mutually with glue special between each layer, also can adopt the heat bonding pressing to connect, make liner 3 grey cloths, the moulding that needs with material distributing machine cutting design under scissors or the moulding promptly cuts out described liner 3 again.Figure 3 shows that helmet liner 3 expanded views, be to take the front portion of crown 4 and cap defensive wall 8 apart the view that launches the back, comprise the cap defensive wall 8 and the crown interconnective 4 that are trapped among on the head circumference with it, both all match with vibration damping layer 2 inner surface, on described cap defensive wall 8 and crown 4 inner surfaces ventilation groove 9 are arranged.The ventilation groove 9 of described cap defensive wall 8 is made for the vertical groove that vertically is 0-45 ° of any angle arrangement, the ventilation groove of described crown is made for the groove of arranging by fore-and-aft direction, can also make a transversal ventilation groove (not shown) that intersects with described vertical ventilation groove 9 on cap defensive wall 8 circumferencial directions, the edge-covering cloth and the vibration damping layer 2 that will be connected with the cap defensive wall other end with glue special are adhesively fixed.Liner also can adopt fire proofing to make, and described lining cloth layer is fire-retardant looped fabric, and described sponge strip layer and spongy layer material are flame-retardant sponge.Because fire proofing has resistant to elevated temperatures characteristic, so, only can adopt glue special bonding.

During use, when the ventilating opening on helmet surface is opened, from ventilating opening 7 on vibration damping layer 2 air channel 6 and the air that enters of airway 5 can be around head rotation and along ventilation groove 9 from the helmet bottom discharge, form air flowing between helmet liner 3 inner surfaces and head, make inner helmet ventilate, distribute heat improves the comfortableness that the driver wears the helmet well.Select the helmet that has the transversal ventilation groove for use, its transversal ventilation groove can quicken horizontal air rotation and flow, heat radiation better.
