Abstract
Description
Technical Field
[0001] The invention relates to a helmet for a fighter plane, and in particular to a helmet customization method based on eye positions. Background Art
[0002] In addition to basic protection functions, current fighter helmets also have extended functions such as display, positioning, and night vision. To ensure the realization of these extended functions, the helmets are designed with a theoretical eye position (i.e., pupil). When the wearer's pupil is located at the pupil, functions such as display, positioning, and night vision can be realized.
[0003] For helmets with extended functions, the current manufacturing method is to add complex adjustment straps inside general helmets. After the wearer wears the general helmet, the adjustment straps are adjusted using complex tooling to adjust the wearer's pupils to the pupil position and then the adjustment straps are fixed. This method relies on the adjustment straps to forcibly fix the wearer's head, which is not only inefficient but also has poor comfort and cannot be promoted on a large scale. Summary of the invention

When making a customized hard liner, first scan the wearer's head shape to obtain a head shape digital model, then assemble the head shape digital model into the helmet shell digital model, let the head shape digital model visually view the heading display area and let the pupil coincide with the pupil in the helmet shell digital model, then correct the head shape digital model to obtain a head shape surface A, then perform an overall normal surface offset on the head shape surface A to obtain a customized surface B, then use the customized surface B to cut a universal hard liner blank shape to obtain a customized hard liner shape, and then process the universal hard liner blank according to the customized hard liner shape to obtain a customized hard liner.
[0006] Preferably, the upper surface of the general hard liner blank is consistent with the inner surface of the helmet shell, the coverage size is designed according to the protection area requirements in GJB1564A-2003, and the whole is thickened by 40 mm from the upper surface to the inside.
[0007] Preferably, when making the universal hard liner blank using the universal hard liner blank shape, firstly make a corresponding mold according to the universal hard liner blank shape, and then make the universal hard liner blank using the mold.
[0008] Preferably, the general hard liner blank is formed by foaming hard foam.
[0009] Preferably, the universal soft lining cap has two types, thin and thick; the thickness H of the thin universal soft lining cap is 15mm, and when the weight of the helmet shell M is less than 1.5kg, the thin universal soft lining cap is selected; the thickness H of the thick universal soft lining cap is 20mm, and when the weight of the helmet shell M is greater than or equal to 1.5kg, the thick universal soft lining cap is selected.
[0010] Preferably, the outer layer of the universal soft lining cap is made of knitted cloth, and the inside is filled with soft foam to ensure shape and thickness.
[0011] Preferably, when scanning the head shape of the wearer to obtain the head shape digital model, the wearer wears a headgear to restrain the hair, so as to obtain a smoother head shape digital model of the wearer.
[0012] Preferably, when the head shape digital model is modified to obtain the head shape curved surface A, it is ensured that the head shape curved surface A fits the surface shape of the head shape digital model with a spacing of no more than 3 mm, and the curvature of the head shape curved surface A is continuous, without obvious bumps, and the draft angle is positive.
[0013] Preferably, when the head-shaped curved surface A is subjected to an overall normal curved surface offset to obtain the customized curved surface B, the offset distance L=(10+H) / 2M, where M is the weight of the helmet shell and H is the thickness of the general soft lining cap.
[0014] Preferably, when processing the general hard liner blank into the customized hard liner, the outer surface of the general hard liner blank is positioned and fixed, and the inner surface of the general hard liner blank is processed according to the customized hard liner shape using a cutting device.
[0015] The beneficial effects of the present invention are: This method takes into account and meets the wearing needs of wearers with different head shapes during design.

DETAILED DESCRIPTION
[0024] The present application is further described below in conjunction with the accompanying drawings and embodiments.
[0025] The present application discloses a helmet customization method based on eye position, and the overall process is: firstly, a general hard liner blank and a general soft liner cap 3 are manufactured, and then a customized hard liner 11 is manufactured; Figure 7 As shown, the customized hard liner 11 and the universal soft liner cap 3 are then sequentially installed into the helmet shell 1 to obtain a customized helmet.
[0026] When making general hard liner blanks: Figure 1 As shown, first extract the inner surface of the helmet shell 1 and then thicken it inward by a certain size to form a universal hard liner blank shape 2 (the upper surface of the universal hard liner blank shape 2 is consistent with the inner surface of the helmet shell 1, the coverage size can be designed according to the protection area requirements in GJB1564A-2003, and the overall thickening from the upper surface to the inside can be selected to be about 40mm); then use the universal hard liner blank shape 2 to make a universal hard liner blank, that is, make a corresponding mold according to the universal hard liner blank shape 2, and then use the mold to make a universal hard liner blank, and the universal hard liner blank can be formed by polystyrene foam or other hard foams.
[0027] When making a universal soft lining cap 3: Figure 2As shown, the upper surface of the universal soft lining cap 3 is slightly larger than the upper surface of the universal hard lining blank and is offset inward as a whole. The outer layer of the universal soft lining cap 3 is made of knitted cloth, and the interior can be filled with polyurethane soft foam or other soft foams to ensure the shape and thickness. In this embodiment, the universal soft lining cap 3 has two types, thin and thick. The thickness H of the thin universal soft lining cap 3 is 15mm. When the weight M of the helmet shell 1 is less than 1.5kg, the thin universal soft lining cap 3 is selected. The thickness H of the thick universal soft lining cap 3 is 20mm. When the weight M of the helmet shell 1 is greater than or equal to 1.5kg, the thick universal soft lining cap 3 is selected.
[0028] When making the customized hard pad 11: first scan the head shape of the wearer to obtain the head shape digital model 6, and the wearer must wear a headgear to restrain the hair to obtain a smoother head shape digital model 6 of the wearer; Figure 3 As shown, the head form digital model 6 is then assembled into the helmet shell digital model 4, so that the head form digital model 6 can visually view the heading display area 5 and the pupil coincides with the pupil 7 in the helmet shell digital model 4; Figure 4 As shown, the head form digital model 6 is then modified to obtain the head form curved surface A8, ensuring that the head form curved surface A8 fits the head form digital model 6 in shape, the spacing is no more than 3 mm, and the curvature of the head form curved surface A8 is continuous, without obvious concave-convex, and the draft angle is positive, and then the head form curved surface A8 is offset as a whole in the normal surface to obtain the customized curved surface B9. In this embodiment, the offset distance L=(10+H) / 2M, where M is the weight of the helmet shell 1 and H is the thickness of the universal soft lining cap 3; Figure 5 As shown, the custom surface B9 is then used to cut the universal hard liner blank shape 2 to obtain the custom hard liner shape 10; Figure 6 As shown, the universal hard liner blank is then processed according to the customized hard liner shape 10 to obtain the customized hard liner 11, that is, the outer surface of the universal hard liner blank is positioned and fixed, and the inner surface of the universal hard liner blank is processed according to the customized hard liner shape 10 using a cutting device.
