detailed description

The technical solutions in the embodiments of the present invention will be clearly and completely described in the following with reference to the accompanying drawings in the embodiments of the present invention. Embodiments, but not all of the embodiments. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments of the present invention without creative efforts are within the scope of the present invention.

As shown in Figures 1 to 3, the present invention provides an embodiment of an illuminated helmet.

The light helmet comprises an outer casing 1 and an inner casing 3 which is tightly fixed to the outer casing 1. The inner casing 3 and the outer casing 1 are provided with a light-emitting strip. The outer casing 1 is provided with a strip-shaped fixing hole 12 at the position of the light-emitting strip 4 at the fixing hole. 12 is provided with a light-transmissive groove 2 for accommodating the light-emitting strip, and the opening of the light-transmitting groove 2 is provided with an extending portion 20 extending outward.

Specifically, the substrate of the outer casing 1 usually adopts a PC sheet, and the raw material of the PC sheet is colorless. In order to make the helmet more beautiful, a pattern or a pattern may be required for silk screen printing or coating on the side of the PC sheet, and the blister is performed. When there is no graphic or pattern side, it is in contact with the mold, so that the graphic pattern is not damaged during the blistering.

The inner casing 3 is injection molded using an EPS material. The light transmissive groove 2 has a zigzag shape in a cross section perpendicular to the length, and the bottom of the light transmissive groove 2, that is, the convex surface passes through the fixing hole 12, and the convex surface is higher than the outer casing 1 The surface of the light-transmissive groove 2 is in contact with the inner side of the outer casing 1 to ensure that the outer casing 1 of the light-transmissive groove 2 is fixed in the inner layer of the mold, and the EPS material is not easily passed from the inner layer through the fixing hole 12 and the transparent groove. The gap between 2 is exposed. The outer layer 1 is usually a bright color system, and the inner layer material such as EPS is usually gray or black gray. When the inner layer 3 is exposed in the middle portion of the outer casing 1, the appearance of the product is seriously affected, thereby causing defects in product quality.

In order to prevent the light-transmitting groove 2 from being loosened after being placed in the fixing hole 12, the light-transmitting groove 2 and the inner layer 1 can be well fixed by glue or the like on the edge of the light-transmissive groove 2, as shown in FIG.

The light-emitting strip 4 includes an FPC board 40 and an LED lamp 41 disposed on the FPC board 40. The number of the LED lamps 41 is set as needed, and may be one, two or more. The light-emitting strip 4 is placed in the light-transmitting groove 2 before the inner layer 3 is injection-molded, so that the light-emitting surface of the LED lamp 41 is close to the bottom of the light-transmitting groove 2.

Since it is not necessary to preliminarily provide a light-transparent white space on the substrate PC sheet of the outer layer 1, it is possible to avoid the influence of temperature and pressure on the outer layer 1 during the plastic forming, and the light-transmissive position of the white space is shifted to cause the colored region to be colored. Offset to the light exit position, affecting the aesthetics and quality of the product helmet, improving the production efficiency of the luminous helmet and reducing the production cost. The blank area means that different shapes, patterns or colors are set according to requirements when the helmet is produced, so that the light source disposed between the outer layer and the inner layer can be emitted from the surface of the helmet, and the pattern, the pattern or the color will be transparent. The light area is left white, allowing the light energy of the light source to exit the surface of the helmet. At the same time, since the light-emitting strip 4 is located in the light-transmitting groove 2, and the light-transmitting groove 2 is higher than the surface of the outer layer 1, the range of the emitted light can be made wider.

In order to facilitate the better fixing of the transparent groove 2 and the fixing hole 12, the offset of the inner layer 3 can be prevented from occurring when the inner layer 3 is pressed at a high temperature, and a matching structure is arranged between the transparent groove 2 and the fixing hole 12, as shown in FIG. 4 to FIG. 7 is shown. The fixing structure includes a fixing groove 21 disposed at an edge of the transparent groove, and a fixing strip 13 extending inwardly and engaging with the fixing groove 21 is disposed at an edge of the fixing hole 12, and the depth of the fixing groove 21 is preferably fixed and fixed. The height of the strip 13 is equivalent. Since the light-transmitting groove 2 passes through the fixing groove 21, the fixing strip 13 can be fixedly fixed and fixed, so that the high temperature of the inner layer forming of the EPS material does not cause the edge of the light-transmitting groove 2 and the fixing hole 12 to be 12 An offset occurs, causing local EPS material to be exposed, which affects product quality.

In order to avoid damage to the colored layer during the injection, resulting in poor appearance of the casing, a package may be used. Coloring is included, but not limited to, coating, silk screen, and the like. Applying an adhesive layer on the outside of the protective layer facilitates better fusion of the outer layer and the inner layer when the inner layer EPS material is injected, so that the outer layer is not easily separated from the inner layer. The adhesive layer may also be disposed directly on the inside of the outer casing.

As shown in FIG. 8, the present invention also provides a method for manufacturing a illuminating helmet, the method for manufacturing the illuminating helmet comprising:

In the S10 outer casing and the transparent groove forming step, all the inner sides of the PC sheet of the outer casing base material are colored, the outer casing is formed by blistering, and the PC sheet of the transparent groove substrate is blister-molded to form a transparent groove, that is, two pieces of PC pieces are taken, The inside of the PC sheet of the outer shell substrate is completely colored, and the colored PC sheet is respectively blister-formed to form a shell and the uncolored PC sheet is blister-formed to form a light-transmissive groove;
