Description

Technical Field

[0001] This utility model relates to the field of hat products, specifically to a forehead structure of a helmet and a helmet. Background Technology

[0002] A helmet is a head protection device used by drivers and passengers. Its primary purpose is to protect the driver's head in the event of an impact, preventing or mitigating injury and even saving the driver's life. Therefore, the design of each part of the helmet's structure is crucial.

[0003] The existing helmet forehead structure design has a tendency to misalign and separate after prolonged use. Specifically, the forehead is one of the areas where the hand grips the helmet. If the structure in this area is only designed with adhesive, the forehead area may protrude forward after a certain period of use, obstructing the opening and closing of the visor. In addition, the structure is not stable enough, reducing protection. Utility Model Content

[0004] The purpose of this invention is to provide a forehead structure for a helmet and a helmet in order to improve the problem of poor stability in existing helmet forehead structure designs.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a forehead structure for a helmet, wherein the forehead portion of the helmet is provided with a through hole for fitting and installing the forehead structure, and includes a forehead body;

[0006] The side protrusion of the forehead body is provided with at least one B-point structure, and the B-point structure forms a first stepped groove with the front end surface of the forehead body.

[0007] The forehead body is provided with at least one ventilation hole that extends through the inside and outside, and a limiting groove is provided on the front end surface of the forehead body, which is connected to the top surface of the forehead body.

[0008] Preferably, the width of the B-point structure gradually increases from the outside inwards.

[0009] Preferably, the top of the forehead body is provided with a second stepped groove.

[0010] Preferably, an adhesive layer is provided between the forehead body and the through hole.

[0011] Preferably, the inner side of the forehead body is provided with a plurality of spaced grooves, and the ventilation holes are provided on the grooves.

[0012] A helmet is also provided, including the forehead structure of the helmet as described above.

[0013] By adopting the above technical solution, this utility model has the following advantages compared with the prior art:

[0014] 1. In this embodiment, a point B structure and a first stepped groove are designed on the forehead body. When engaged in the through hole, the first stepped groove can limit the movement and prevent the forehead body from being pushed out of the through hole. In this way, the design of the structure can prevent the forehead body from being pushed out and affecting the opening and closing of the lens during long-term use, thereby improving the stability of the structure and the comfort of use.

[0015] 2. In this embodiment, the forehead body is designed with a limiting groove. The limiting groove increases the limiting point, improves the stability of the structure, and allows for the engagement of the structure in different directions, achieving a fast-fitting assembly design.

[0027] Example 1

[0028] Please refer to Figure 1 , Figure 2 and Figure 3 As shown, this embodiment provides a forehead structure for a helmet 1. The forehead portion of the helmet 1 is provided with a through hole for fitting and mounting the forehead structure, including a forehead body 10. At least one B-point structure 101 is provided on the side of the forehead body 10. The B-point structure 101 is a protrusion on the side of the forehead body 10. A first stepped groove 102 is formed between the B-point structure 101 and the front end face of the forehead body 10. At least one ventilation hole 103 is provided on the forehead body 10 and penetrates through the inside and outside. A limiting groove 104 is provided on the front end face of the forehead body 10, and the limiting groove 104 is connected through the top surface of the forehead body 10.

[0029] Specifically, a through hole is designed on the forehead of the helmet 1 to fit into the forehead body 10, and the outline of the through hole matches the outer outline of the forehead body 10, for example, both being rectangular outlines. A stepped structure is designed on the side of the through hole to adapt to the B-point structure 101, forming a locking structure that prevents the forehead body 10 from being accidentally pushed out of the through hole. This structural restraint prevents the forehead body 10 from loosening or shifting after a period of use, improving the stability of the structure.

[0030] Furthermore, a limiting groove 104 is added to the front end face of the forehead body 10, and a corresponding protrusion is set on the helmet 1 to engage with the limiting groove 104 for limiting, thereby adding a limiting point, further enhancing the fixing effect of the forehead body 10, improving the stability of the limiting, and improving the safety of use.

[0031] like Figure 1 and Figure 2As shown, in this embodiment, multiple ventilation holes 103 are designed on the forehead body 10, which not only enhances air circulation and reduces the wearer's stuffiness, but also reduces the weight of the helmet 1 and improves wearing comfort.

[0032] In this embodiment, the width of the B-point structure 101 gradually increases from the outside to the inside, and the inward tilt design enhances the tightness of the fit with the through hole, preventing accidental detachment. At the same time, it facilitates quick installation and removal of the forehead body 10 for production operations.

[0033] Furthermore, such as Figure 3 As shown, in this embodiment, an adhesive layer 106 is provided between the forehead body 10 and the through hole to improve the bonding strength between the forehead body 10 and the through hole, ensuring that it will not fall off during long-term use, thereby improving the structural durability and enhancing the overall structural stability, and meeting the requirements of high-intensity use.

[0034] like Figure 1 As shown, in this embodiment, the top of the forehead body 10 is provided with a second stepped groove 105. The design of the second stepped groove 105 increases the support force of the edge of the forehead body 10, improves the stability of the matching structure, further enhances the overall impact resistance of the helmet 1, and improves the structural stability of the helmet 1 during long-term use.

[0035] like Figure 2 As shown, in this embodiment, a plurality of spaced grooves 107 are provided on the inner side of the forehead body 10, and ventilation holes 103 are provided on the grooves 107. The design of the grooves 107 facilitates air circulation inside the helmet 1, forming an effective air duct, further reducing the wearer's head temperature and improving comfort. At the same time, the structure of the grooves 107 also enhances the overall strength of the forehead body 10, ensuring that stress can be effectively dispersed when subjected to external impact, thus protecting the wearer's safety.

[0036] Example 2

[0037] like Figure 4 As shown, this embodiment provides a helmet, including the forehead structure of helmet 1 as described in embodiment 1. The design of the forehead structure can improve the structural stability of the forehead position and prevent the structure from loosening. At the same time, it can also be bonded with adhesive to enhance the connection strength between the forehead body and the helmet, ensuring that it will not fall off after long-term use and improving the durability and safety of the structure.

[0038] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
