Description

Technical Field

[0001] This utility model relates to the field of protective gear technology, specifically to a helmet with an inward-pushing outer lens. Background Technology

[0002] In the field of personal protective equipment, helmets are crucial safety devices for activities such as cycling and motorcycling, and their visor design directly impacts the user's safety and experience. Currently, most traditional helmets employ a design that combines a full-length external visor with a half-length internal visor. However, this design has revealed numerous problems in practical use, resulting in poor ease of use.

[0003] The separate use of the outer full lens and inner half lens requires users to frequently adjust the lens state according to different environments and needs. This frequent operation not only distracts the rider's attention and increases the burden of operation, but also brings serious safety hazards. In addition, the inner half lens has poor sealing effect and cannot effectively prevent dust, rain and other external debris from entering the helmet, affecting the user's vision and comfort, and may also cause damage to the user's eyes. Utility Model Content

[0004] To achieve the above objectives, the present invention provides the following technical solution: an external lens push-in helmet, comprising a helmet body and a viewing window opened on the front side of the helmet body, wherein a lens that can block the viewing window is rotatably connected inside the helmet body, the bottom of the lens has an edge extending out of the viewing window, and the edge of the viewing window has a convex edge structure for sealing the lens.

[0005] Furthermore, the convex edge structure includes a top convex edge and a bottom convex edge, wherein the bottom convex edge is fitted with the inner side of the edge of the lens, and the top convex edge is fitted with the upper surface of the lens.

[0006] Furthermore, a brim located above the viewing window is fixed to the outer side of the helmet body by a locking structure. A slot is provided on the helmet body, and a groove block is formed on the back of the brim to fit and engage with the slot.

[0007] Furthermore, the two side walls of the lens are respectively provided with inclined arc-shaped waist holes, the bottom edge of the arc-shaped waist hole is an inward protrusion, the protrusion is an outward V-shaped groove, and the left and right inner sides of the helmet body are provided with a rotating shaft passing through the side wall of the lens and a guide shaft located in the arc-shaped waist hole.

[0008] Furthermore, a ventilation component is provided on the front side of the neck of the helmet body, and an arc-shaped protective plate is provided on the inner side of the neck of the helmet body. An air vent is provided on the inner top of the arc-shaped protective plate, and the air vent is connected to the ventilation component.

[0009] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0010] This helmet with an inward-pushing outer lens achieves a comprehensive seal for the lens through a convex edge structure inside the visor. The top convex edge fits snugly against the upper surface of the lens, while the bottom convex edge fits tightly against the edge. Furthermore, the protrusion of the bottom convex edge fits snugly against the back of the lens. This multi-layered sealing structure effectively prevents dust, rain, and other external debris from entering the helmet, ensuring clear vision for the rider, improving wearing comfort, and preventing debris from harming the eyes. The brim effectively blocks sunlight and rain, providing better protection for the rider. Attached Figure Description

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figure 1-5 An external lens push-in helmet in this embodiment includes a helmet body 1 and a viewing window 5 opened on the front side of the helmet body 1. A lens 11 that can block the viewing window 5 is rotatably connected between the left and right side walls of the helmet body 1. The bottom of the lens 11 forms an edge 112 extending out of the viewing window 5. The edge of the viewing window 5 forms a convex edge structure for sealing the lens 11.

[0019] In the above structure, a viewing window extends along the edge, which makes it easy to slide the lens into and out of the helmet body. When the lens is slid down, the convex edge structure can seal the connection between the lens and the viewing window, thereby effectively preventing dust, rain and other external debris from entering the helmet.

[0020] The convex edge structure includes a top convex edge 51 and a bottom convex edge 51. The bottom convex edge 51 is fitted with the inner side of the edge 112 of the lens 11 to form a bottom sealing surface. The top convex edge 51 is fitted with the upper surface of the lens 11 to block the entry path of debris from above. The top convex edge 51 is folded inward, and the bottom convex edge 51 is folded upward. The bottom convex edge abuts against the back of the lens 11. Through the double fitting of the top and bottom, a sealing structure is formed, which effectively prevents dust, rainwater and other external debris from entering the helmet through the gap between the viewing window 5 and the lens 11. A sealing strip can also be installed on the convex edge 51 to improve the sealing effect.

[0021] The lens 11 has inclined arc-shaped waist holes 113 on both side walls. The bottom edge of each arc-shaped waist hole 113 has an inward protrusion, and the protrusion has an outward V-shaped groove 114. The helmet body 1 has a pivot passing through the side wall of the lens 11 and a guide shaft located in the arc-shaped waist hole 113 on the left and right inner sides. When the lens is moved, the guide shaft changes position in the arc-shaped waist hole. When it reaches the middle position, it is squeezed to the other end by the protrusion and the V-shaped groove, thus realizing the positioning of the lens opening and closing.

[0022] Meanwhile, a slot 41 is provided on the outer side of the helmet body 1 above the visor window 5, and a groove block is formed on the back of the visor 4 to fit the slot 41. During installation, the groove block is inserted into the slot and fixed by a locking structure such as screws or buckles, so that the visor window can stably cover the area above the visor window, effectively blocking sunlight and rain and preventing direct sunlight from affecting the rider's vision.

[0023] Further explanation: a ventilation component 9 is provided on the front side of the neck of the helmet body 1. An arc-shaped protective plate is located on the inner side of the neck of the helmet body 1, and an air vent is located on the inner top of the arc-shaped protective plate. The air vent is connected to the ventilation component 9. The ventilation component is a standard feature in motorcycle helmets and therefore will not be explained further. Through the cooperation of the ventilation component and the air vent, air exchange can be achieved inside the helmet body.

[0024] The entire workflow is now complete, and anything not described in detail in this specification is existing technology known to those skilled in the art.
