Description

Improved structure of safety helmet

Technical field:

The utility model relates to a safety helmet; in particular, it refers to a helmet that is divided into several parts according to the design or decoration area, and a decoration or pattern layer is provided to cover the set area of the decoration, and the The utility model relates to a safety helmet in which the helmet and the cushioning material are integrally formed.

Background technique:

After printing or spraying paint on the surface of the plastic shell material or pasting the decorative part/pattern layer, it is tightly fixed in a vacuum forming device with a cap-shaped module, and a foam material filler is used to make the plastic shell It is a known technology to cover the foam filler body with the body material to complete a safety helmet structure to be worn by cyclists or horse riders.

One issue related to making this type of helmet is that in order to increase the texture or attractiveness of this type of safety helmet, the surface of the helmet is usually painted with color or pasted with a pattern layer or pasted with a similar cloth material. In fact, after the plastic shell is formed, the operation of painting and pasting the pattern layer or cloth material is carried out on the predetermined design area (or set position) on the surface of the plastic shell (the operation can be done between the plastic shell and before or after the combination of the foam filling body). As is known to those skilled in the art, the construction of this helmet suffers from the following disadvantages:

1. The pasting operation of the pattern layer must rely on skilled personnel. The pattern layer sticker or cloth is arranged on the set position or area of the helmet surface according to the design plan, so there are certain boundaries and outlines; if the operator is not skilled enough, it will often cause the pasted pattern layer or cloth material Irregularity or wrinkling occurs near the edge, such as the situation depicted in part A in FIG. 1 . This situation is particularly likely to occur at the edge of the outline of the pattern layer; this is because when pasting, in order to make the entire pattern layer sticker or patch stick smoothly on the surface of the plastic shell, the operator will instinctively push For the pattern layer, try to make the front of the pattern layer flat on the surface of the plastic shell, so the partial edge of the pattern layer often protrudes or crosses the above-mentioned set area or position planned on the plastic shell. Especially for those stickers or patches with elasticity, it will be more obvious that their edges protrude or cross the set area or position. Usually operators have to spend extra time on trimming, and try to avoid damaging other painted or pasted parts. This shows considerable difficulty in fabrication or processing operations and increases fabrication time.

2. In order to reduce the situation where the edge of the pattern layer protrudes or crosses the above-mentioned setting area or position planned on the plastic shell, the size of the pattern layer is specially required to make the outline of the pattern layer as close as possible to the design on the shell. match the specified area. But the size of the sticking material that those elastic pattern layers or cloth materials are formed is more difficult to control; A situation that protrudes or crosses the set area, and this situation is not what we expect.

3. In some cases where trimming is not possible or the trimming is not neat enough, in order to keep the edge areas of the pattern layer that protrude or cross the planning boundary, it can be determined to be pasted in the planned area, and the pattern layer can only be pressed as much as possible In the edge area, this will also cause the local area of the edge of the pattern layer to produce a situation similar to the above-mentioned extrusion or wrinkling.

4. In another embodiment of pasting the pattern layer, if the thickness of the pattern layer sticker or patch is thicker, it will actually form a slight depression in the planned setting area when the plastic shell is formed. The concave area, so that after the thicker pattern layer is pasted in the concave area, the surface of the whole helmet is smooth. In this embodiment, the edge portion of the pattern layer is specifically required not to protrude or go over the recess area. Because if the local edges of the pattern layer protrude, the entire helmet surface will be uneven, resulting in defective products.

5. If the personnel performing the pasting operation are not skilled enough, it will significantly increase the frequency of situations similar to extrusion or wrinkling in the local area at the edge of the above-mentioned pattern layer. Especially when carrying out pasting operations sometimes, unskilled operators also increase the situation that the glue adheres to other areas of the plastic shell and causes contamination.

6. At the present stage, when implementing the pasting operation of the pattern layer, the industry still needs to rely on a large amount of labor, and cannot use machines to perform a large number of processing operations, which shows that it is difficult for the industry to obtain a large number of skilled operators; relatively It also makes the quality control of product production difficult.

Typically, the above reflects that the design and manufacture of the safety helmet structure are still not ideal. If redesign considers the organization structure of this helmet, make its structure different from prior art, will change its manufacture and processing type, and be different from old method; In fact, also can improve the existing shortcoming of known technology. In practice, these issues have not been improved or fully resolved.

Utility model content:

The technical problem to be solved by the utility model is to provide an improved structure of a safety helmet in view of the deficiencies of the above-mentioned prior art; it can improve the unevenness of the joints of known helmet decorations or pattern layers, time-consuming processing or production, and a lot of technical skills Labor, reduce its defective rate and other issues.

In order to solve the above technical problems, the technical solution adopted by the utility model is: an improved structure of a safety helmet, including a first part, a second part, and a decorative part or pattern layer, the first part has an outer surface and a Inner surface; the second part has an outer surface and an inner surface; the decorative part or pattern layer is pasted and coated on the outer surface of the second part, and the feature is that it also includes an extension area formed on the first part Between and the second part; at least part of the edge of the decoration or pattern layer enters the extension area after passing over the edge of the second part.

Another technical solution adopted by the utility model is: an improved structure of a safety helmet, including a first part, a second part and a decorative part or pattern layer, the first part has an outer surface and an inner surface; the first part has an outer surface and an inner surface; The second part 12' has an outer surface and an inner surface; the decorative part or pattern layer is glued and covered on the outer surface of the second part 12', and its characteristic is that it also includes a joint part arranged on the second part 12', so that the second part 12' is joined to the first part; at least part of the edge of the decorative part or pattern layer is folded towards the inside of the second part 12' after passing over the edge of the second part 12' surface side.
