AI Technical Summary

Technical Problem

The existing helmet liner is made of a hard material, which does not adequately disperse impact energy and is not repairable, making it difficult to replace the entire helmet.

Method used

The helmet liner is divided into a softer upper liner and a harder lower liner, both made of polystyrene foam. The upper liner has pressure relief protrusions and the lower liner has mounting grooves. The splicing design allows for easy disassembly and assembly, and the upper liner can be replaced separately if damaged.

Benefits of technology

It improves the dispersion of impact energy, enhances protective performance, and allows for individual replacement of the upper liner when damaged, reducing maintenance costs.

Description

Technical Field

[0001] This utility model relates to the field of safety helmets, specifically to a safety helmet liner. Background Technology

[0002] Existing safety helmets all use one-piece molded liner, which is generally hard and has the defect of insufficient impact energy dispersion. Moreover, the liner needs to be replaced as soon as it is slightly deformed, which is a defect of being unrepairable. Utility Model Content

[0003] In order to overcome the shortcomings of the prior art, this utility model provides a safety helmet liner with good protective performance and easy disassembly and assembly.

[0004] The technical solution adopted by this utility model is: a safety helmet liner, which includes an upper liner and a lower liner formed by splicing. The upper liner is made of soft material and the upper surface of the upper liner is provided with a number of pressure relief protrusions for cushioning.

[0005] The lower liner is provided with an installation groove for the upper liner to be installed. The front and rear sides of the installation groove are provided with positioning bosses, and the front and rear sides of the upper liner are provided with positioning grooves corresponding to the positioning bosses.

[0006] Both the upper and lower linings are provided with several perforated holes.

[0007] The material of the lower lining is harder than that of the upper lining.

[0008] Both the upper and lower linings are made of polystyrene foam, with the upper lining coated with a soft coating and the lower lining coated with a hard coating.

[0009] The upper surface of the liner is provided with a recessed groove surrounding the pressure relief protrusion.

[0010] The beneficial effects of this utility model are: This technical solution separates the inner lining of the safety helmet into an upper lining and a lower lining. The upper lining is made of a softer material. When impacted, the pressure relief protrusion deforms, thereby playing a buffering role. In addition, if the upper lining is damaged by impact, it can be removed and replaced separately. It has the advantages of good protective performance and convenient disassembly and assembly. Attached Figure Description

[0011] Figure 1 This is a schematic diagram of the structure of the safety helmet liner according to an embodiment of the present invention.

[0012] Figure 2 This is a schematic diagram showing the disassembled structure of the helmet liner. Detailed Implementation

[0013] The embodiments of this utility model will be further described below with reference to the accompanying drawings:

[0014] As shown in the figure, a safety helmet liner includes an upper liner 1 and a lower liner 2 formed by splicing. The upper liner 1 is made of soft material, and the upper surface of the upper liner 1 is provided with a number of pressure relief protrusions 3 for cushioning. This technical solution separates the safety helmet liner into an upper liner and a lower liner. The upper liner is made of a softer material. When impacted, the pressure relief protrusions deform to play a cushioning role. In addition, if the upper liner is damaged by impact, it can be removed and replaced separately. It has the advantages of good protective performance and convenient disassembly and assembly.

[0015] The lower liner 2 is provided with an installation groove 4 for the upper liner 1 to be inserted. The front and rear sides of the installation groove 4 are provided with positioning bosses 5. The front and rear sides of the upper liner 1 are provided with positioning grooves 6 corresponding to the positioning bosses 5. The installation groove is adapted to the shape of the upper liner so that the upper liner can be inserted. Then the positioning bosses and positioning grooves cooperate with each other to ensure the stable splicing of the upper and lower liners.

[0016] Both the upper liner 1 and the lower liner 2 are provided with a number of hollowed-out holes 7, which allow airflow to circulate and provide ventilation and heat dissipation.

[0017] The lower liner 2 is harder than the upper liner 1. Both the upper liner 1 and the lower liner 2 are made of polystyrene foam. The upper liner 1 is coated with a soft coating, and the lower liner 2 is coated with a hard coating.

[0018] The upper surface of the upper liner 1 is provided with a recessed groove 8 surrounding the pressure relief protrusion 3. After the pressure relief protrusion is deformed by pressure, the recessed groove provides space for the pressure relief protrusion to deform.

[0019] In the description of this utility model, it should be noted that the terms "center," "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description. They do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on this utility model. In addition, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0020] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances. Furthermore, in the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0021] Please note to all technical personnel: Although this utility model has been described according to the specific embodiments above, the inventive concept of this utility model is not limited to this utility model. Any modifications that utilize the inventive concept will be included within the scope of protection of this patent.
