Description

Technical Field

[0001] The present invention relates to a safety helmet, in particular to a safety helmet capable of dispersing impact force. Prior Art

[0002] Common helmets currently consist of a rigid outer shell and a cushioning layer within it. When impacted by an external force, the rigid outer shell first absorbs some of the energy, followed by the cushioning layer, with the remaining energy being borne by the head and cervical spine.

[0003] However, when the external force is strong, the cushioning layer alone cannot withstand the impact, resulting in a large portion of the force being directly transmitted to the head, causing damage. Therefore, there is still room for improvement in the structure of traditional helmets. Summary of the Invention

[0004] The main purpose of the present invention is to provide a safety helmet that can effectively disperse the impact force so that the wearer's head can obtain sufficient protection.

[0005] To achieve the aforementioned primary objectives, the present invention provides a safety helmet comprising a helmet shell, a load-bearing member, and a force-distributing member. The helmet shell comprises a rigid outer shell and a buffer layer, the rigid outer shell having an inner circumference and an outer circumference, the buffer layer being disposed on the inner circumference of the rigid outer shell; the load-bearing member being exposed on the outer circumference of the rigid outer shell; and the force-distributing member being embedded in the buffer layer and connected to the load-bearing member to distribute an impact force borne by the helmet shell or the load-bearing member.

[0006] As can be seen from the above, when the impact force strikes the helmet shell or the force-receiving member, the external force is not only transmitted from the rigid outer cover to the buffer layer, and then from the buffer layer to the force-distributing member, but the external force is also transmitted from the force-receiving member to the force-distributing member, thus effectively dispersing the impact force. Thus, the helmet of the present invention can effectively provide a cushioning and protective effect on the head.

[0007] Preferably, the force-bearing member has a front fixing portion. The force-dividing member has a side bracket, and the side bracket has a front fixing portion. The front fixing portion of the side bracket is assembled to the front fixing portion of the force-bearing member. In this way, the force-bearing member and the side bracket can be quickly assembled.

[0008] Preferably, the force-bearing member comprises two force-bearing plates, each of which has a rear fixing portion. The force-dividing member comprises an intermediate bracket, each of which has two rear fixing portions, the rear fixing portions of the intermediate bracket being fixed to the rear fixing portions of the force-bearing plates. This allows for rapid assembly of the intermediate bracket and the force-bearing plates.

[0009] Preferably, the side brackets have a plurality of fixing slots, and the intermediate bracket has a plurality of side branches, each of which has a side fixing portion, and the side fixing portions of the side branches are fixed to the fixing slots of the side brackets. Thus, the intermediate bracket and the side brackets can be quickly assembled.

[0010] Preferably, the force distribution member further comprises a front bracket having a plurality of fixing slots, and each of the side brackets has a side fixing portion, wherein the fixing slots of the front bracket are fixed to the side fixing portion of each of the side brackets. Thus, the front bracket and each of the side brackets can be quickly assembled.

[0011] The detailed structure, features, assembly, and usage of the impact-dispersing helmet provided by the present invention will be described in the detailed description of the embodiments that follow. However, those skilled in the art will appreciate that the detailed description and the specific embodiments listed for implementing the present invention are intended only to illustrate the present invention and are not intended to limit the scope of the patent application.

[0013] The applicant first clarifies that throughout this specification, including the embodiments described below and the claims of the patent application, directional terms are based on the directions in the drawings. Furthermore, in the embodiments and drawings described below, identical component numbers represent identical or similar components or structural features.

[0014] 1 and 2 , the helmet 10 of the present invention includes a helmet shell 20 , a force-bearing member 30 , and a force-dividing member 40 .

[0015] The cap shell 20 comprises a rigid outer cover 21 and a cushioning layer 24. The rigid outer cover 21 is made of a rigid material such as hard plastic and primarily serves as a protective layer. The cushioning layer 24 is made of a shock-absorbing material such as foam and primarily provides shock absorption and cushioning. As shown in Figure 2, the rigid outer cover 21 has an inner circumferential surface 22 and an outer circumferential surface 23. The cushioning layer 24 is fixed to the inner circumferential surface 22 of the rigid outer cover 21.

[0016] The load-bearing member 30 is made of polyamide (PA). In this embodiment, as shown in Figures 1 and 2, the load-bearing member 30 comprises two load-bearing plates 31. These plates 31 are positioned on the outer circumference 23 of the rigid housing 21 in a left-right opposing arrangement and are exposed to the outside to withstand impact forces. As shown in Figure 4, each load-bearing plate 31 has a plurality of perforations 34. Each perforation 34 is honeycomb-shaped and extends through both the inner and outer sides. This honeycomb-shaped design ensures that each load-bearing plate 31 provides both support and breathability, while also providing a unique visual effect. Furthermore, each load-bearing plate 31 has two spaced-apart front fixing portions 35 at its front end (as shown in Figure 4), and two spaced-apart rear fixing portions 36 at its rear end (as shown in Figure 6). It is worth mentioning that the force-bearing member 30 is mainly configured at the part of the entire helmet 10 that is most vulnerable to impact. Although it is composed of two force-bearing plates 31 in this embodiment, in practice, the force-bearing member 30 can also be integrated into a single component according to actual needs, as long as the size of the force-bearing member 30 is sufficient to cover the part of the entire helmet 10 that is most vulnerable to impact.

[0017] The force distribution member 40 is made of polyamide (PA). As shown in FIG2 , the force distribution member 40 is embedded in the buffer layer 24 of the helmet shell 20 . In this embodiment, as shown in FIG4 and FIG6 , the force distribution member 40 comprises two side brackets 50 , a middle bracket 60 , and a front bracket 70 , wherein:

[0018] The two side brackets 50 are positioned opposite each other and correspond to the undersides of the two load-bearing plates 31. As shown in FIG4 , each side bracket 50 has a ring portion 51 with a plurality of spaced-apart fixing grooves 512 on its inner edge. The ring portion 51 is penetrated by a plurality of hollow portions 52 and 53 of varying sizes (the size and distribution are not limited). These hollow portions 52 and 53 connect the two side brackets 50 and the buffer layer 24 together. Furthermore, as shown in FIG4 , each side bracket 50 further has two spaced-apart front fixing portions 54 and two spaced-apart side fixing portions 55. The two front fixing portions 54 are connected to the top surface of the front edge of the ring portion 51, while the two side fixing portions 55 protrude from the front edge of the ring portion 51. During assembly, as shown in Figures 7 and 8 , the two front fixing portions 54 of the side bracket 50 are fixed to the two front fixing portions 35 of the load-bearing plate 31 by means of snap-fitting, ultrasonic welding, or adhesive bonding, allowing for quick assembly of the side bracket 50 and the load-bearing plate 31. However, in practice, the side bracket 50 and the load-bearing plate 31 are not limited to being assembled using snap-fitting, ultrasonic welding, or adhesive bonding; they can also be integrally formed to achieve the same force transmission effect.

[0019] The middle bracket 60 is located between the two side brackets 50 and is positioned in the center of the entire helmet 10. As shown in Figures 4 and 6, the middle bracket 60 comprises a main frame 61, a plurality of side branches 62, and a rear branch 63. The side branches 62 are arranged in pairs on opposite sides of the main frame 61 and spaced apart along the extension direction of the main frame 61. One end of each side branch 62 is integrally connected to the main frame 61, and the other end of each side branch 62 has a side fixing portion 622. Furthermore, each side branch 62 extends downward in an arc from the main frame 61 toward the side bracket 50. As shown in Figures 9 and 10, the side fixing portions 622 of the side branches 62 are fixed to the fixing slots 512 of the side brackets 50 by snap-fitting, ultrasonic welding, or adhesive bonding, allowing for quick assembly of the middle bracket 60 and the side brackets 50. After assembly, a hollow portion 65 (as shown in FIG. 3 ) is formed between the main trunk 61, the two adjacent front and rear side branches 62, and the side brackets 50. This hollow portion 65 joins the intermediate bracket 60, the side brackets 50, and the buffer layer 24. As shown in FIG. 6 , the rear branch 63 is integrally connected to the rear end of the main trunk 61 and has a hollow portion 632. This hollow portion 632 joins the intermediate bracket 60 and the buffer layer 24. Furthermore, the intermediate bracket 60 has four rear fixing portions 64, which are connected in pairs to the left and right sides of the rear branch 63. These rear fixing portions 64 of the intermediate bracket 60 are secured to the rear fixing portions 36 of the two load-bearing plates 31 by means of interlocking, ultrasonic welding, or adhesive bonding, as shown in FIG. 11 and FIG. 12 , allowing for rapid assembly of the intermediate bracket 60 and the two load-bearing plates 31.

[0020] As shown in Figure 4 , the top edge of the front bracket 70 has four spaced-apart fixing slots 72 . These fixing slots 72 are secured to the side fixing portions 55 of the side brackets 50 by snapping, ultrasonic welding, or adhesive bonding. As shown in Figures 13 and 14 , this allows for quick assembly of the front bracket 70 and the side brackets 50 . After assembly, the front bracket 70 extends forward and downward from the side brackets 50 , positioning the front bracket 70 on the helmet 10 at a position corresponding to the forehead. Furthermore, the front bracket 70 has a plurality of hollow portions 74 and 75 of varying sizes (the size and distribution are not limited). These hollow portions 74 and 75 connect the front bracket 70 to the cushioning layer 24 .

[0021] As can be seen from the above, when the helmet shell 20 or the force-receiving member 30 is impacted by an external force, the external force is not only transmitted by the rigid outer cover 21 to the buffer layer 24, and then transmitted by the buffer layer 24 to the two side brackets 50, the middle bracket 60 and the front bracket 70 of the force-dividing member 40, but the external force is also transmitted by the force-receiving member 30 to the two side brackets 50, the middle bracket 60 and the front bracket 70 of the force-dividing member 40. In this way, the impact force can be effectively dispersed, so that the wearer's head can truly obtain a good cushioning protection effect, thereby achieving the purpose of the present invention.
