Technical Field

[0001] This utility model relates to the field of helmet technology, specifically to a helmet with a breathable function. Background Technology

[0002] Helmets are a common device used to protect the head in daily life. Falls during cycling can cause serious head injuries. Even if cyclists are riding at low speeds along a gentle bike path, safety issues should not be ignored, and helmets are a safety protection tool for the head.

[0003] Current helmets are either not breathable or always breathable. Once worn, helmets cannot be arbitrarily controlled to adjust their breathability according to needs, which makes them inconvenient to use and causes great trouble for people. Utility Model Content

[0004] The purpose of this invention is to provide a helmet with a breathable function to solve the problem mentioned in the background art that existing helmets cannot arbitrarily control whether or not they are breathable according to needs.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a helmet with a breathable function, comprising a helmet body, wherein the top of the helmet body is provided with three sets of equally spaced breathable structures for ventilation inside the helmet body; the breathable structure includes a breathable seat, a small spring, a hook rod, a side cover, and a breathable cover; the breathable seat is embedded inside the helmet body, and the inside of the breathable seat is provided with a breathable cover with two protruding feet that can move up and down; a side cover is fixed on the surface of the breathable seat and outside the breathable cover; the surface of the helmet body is provided with a visor with holes at both ends, and the visor is detachably connected to the helmet body via a quick-release structure.

[0006] Preferably, a small spring is fitted at the center of the vent seat, and the upper and lower ends of the small spring are respectively attached to the side walls of the vent seat and the vent cover. A hook rod is installed inside the vent cover.

[0007] Preferably, the surface of the vent seat has two symmetrical vents, and the two protruding feet of the vent cover are located inside the vents. The inner walls on both sides of the vent seat are provided with limiting grooves with hook grooves at the bottom, and the two ends of the hook rod are located inside the limiting grooves. When the vent cover is pressed to the lowest point, the hook rod engages with the hook groove at the bottom of the limiting groove.

[0008] Preferably, the quick-release structure includes a mounting base, a hook plate, a large spring, a hook post, a sealing ring, and an outer cover. The mounting base is installed on the side wall of the helmet body, and the hook plate is installed on the surface of the mounting base by spring bolts, and the goggles are fitted onto the surface of the hook plate.

[0009] Preferably, the goggles are provided with two outer covers on the outside, and hook posts are inserted into the inner walls of the outer covers, with one end of each hooking through the holes in the goggles and hooking with the hook pieces.

[0010] Preferably, a sealing ring is fixed on the surface of the outer cover and outside the hook post, and the other end of the sealing ring is pressed against the surface of the goggles. A sealing ring is also fitted on the surface of the outer cover for sealing purposes.

[0011] Compared with existing technologies, the advantages of this invention are as follows: This ventilated helmet features a quick-release structure. By pressing the outer cover, the hook pin passes through the eyepiece's hole and inserts into the hook plate on the mounting surface. Rotating the outer cover then engages the hook at the end of the hook pin with the hook plate, while the large spring's force presses the eyepiece firmly in place. When disassembly is needed, simply rotating the outer cover allows the hook at the end of the hook pin to engage with the hook plate, and the large spring's force allows for easy removal and installation of the eyepiece. Furthermore, the ventilated structure allows for easy ventilation. When the helmet needs ventilation, pressing the vent cover moves it down along the limiting groove under the action of the hook rod. When the hook rod engages with the hook groove at the bottom of the limiting groove, the vent cover is locked, allowing the vent to connect to the outside while air inside the helmet is expelled, thus achieving ventilation.

[0020] The present invention provides a helmet with a breathable function, the structure of which is as follows: Figure 1 , Figure 3 as well as Figure 4 As shown, the helmet includes a helmet body 1. The top of the helmet body 1 has three sets of equally spaced ventilation structures 3 for ventilation inside the helmet body 1. Each ventilation structure 3 includes a ventilation seat 31, a small spring 32, a hook 33, a side cover 34, and a ventilation cap 35. The ventilation seat 31 is embedded inside the helmet body 1. Inside the ventilation seat 31 is a movable ventilation cap 35 with two protruding feet. A side cover 34 is fixed to the surface of the ventilation seat 31, outside the ventilation cap 35. A visor 2 with holes at both ends is provided on the surface of the helmet body 1. The visor 2 is connected to the helmet via a quick-release mechanism 4. The helmet body 1 is detachable and connected to each other. A small spring 32 is installed in the center of the vent seat 31. The upper and lower ends of the small spring 32 are respectively attached to the side walls of the vent seat 31 and the vent cover 35. A hook rod 33 is installed inside the vent cover 35. Two symmetrical vents 312 are opened on the surface of the vent seat 31. The two protrusions of the vent cover 35 are located inside the vents 312. Limiting grooves 311 with hook grooves at the bottom are opened on the inner walls on both sides of the vent seat 31. The two ends of the hook rod 33 are located inside the limiting grooves 311. When the vent cover 35 is pressed to the lowest point, the hook rod 33 hooks into the hook groove at the bottom of the limiting groove 311.

[0021] During implementation, by pressing the vent cover 35, the vent cover 35 will move down along the limiting groove 311 under the action of the hook rod 33. When it moves down to the point where the hook rod 33 engages with the hook groove at the bottom of the limiting groove 311, the vent cover 35 is locked. At this time, the vent 312 can be connected to the outside, and the air inside the helmet body 1 will be discharged through the vent 312.

[0022] Furthermore, such as Figure 2 , Figure 5 as well as Figure 6 As shown, the quick-release structure 4 includes a mounting base 41, a hook plate 42, a large spring 43, a hook post 44, a sealing ring 45, and an outer cover 46. The mounting base 41 is mounted on the side wall of the helmet body 1, and the hook plate 42 is mounted on the surface of the mounting base 41 by a spring bolt 421. The goggles 2 are fitted onto the surface of the hook plate 42. Two outer covers 46 are provided on the outer side of the goggles 2. The hook post 44 is inserted into the inner wall of the outer cover 46, and one end of the hook post 44 passes through the hole of the goggles 2 and hooks with the hook plate 42. A sealing ring 45 is fixed on the surface of the outer cover 46 and located outside the hook post 44. The other end of the sealing ring 45 is pressed against the surface of the goggles 2. A sealing ring 45 is also fitted on the surface of the outer cover 46. The sealing ring 45 is used for sealing.

[0023] During implementation, by pressing the outer cover 46, the outer cover 46 causes the hook post 44 to pass through the hole in the goggles 2 and insert into the hook piece 42 on the surface of the mounting base 41. Then, by rotating the outer cover 46, the hook at the end of the hook post 44 hooks into the hook piece 42. At the same time, the elastic force of the large spring 43 will press and fix the goggles 2 under the support of the outer cover 46.

[0024] Working principle: When in use, first install the goggles 2 to the helmet body 1. During installation, the quick-release structure 4 is used for fixation. When the quick-release structure 4 is activated, by pressing the outer cover 46, the outer cover 46 drives the hook post 44 to pass through the hole of the goggles 2 and insert into the hook piece 42 on the surface of the mounting base 41. Then, by rotating the outer cover 46, the hook at the end of the hook post 44 hooks with the hook piece 42. At the same time, the elastic force of the large spring 43 will press and fix the goggles 2 under the support of the outer cover 46. When it is necessary to disassemble, simply rotate the outer cover 46 so that the hook at the end of the hook post 44 hooks with the hook piece 42. Then, the goggles can be removed by the elastic force of the large spring 43, thus realizing the quick installation and removal of the goggles 2.

[0025] When the helmet needs ventilation, the ventilation cover 35 is pressed, and the ventilation cover 35 moves down along the limiting groove 311 under the action of the hook rod 33. When it moves down to the point that the hook rod 33 engages with the hook groove at the bottom of the limiting groove 311, the ventilation cover 35 is locked. At this time, the ventilation port 312 is open to the outside, and the air inside the helmet body 1 will be discharged through the ventilation port 312, thereby realizing the ventilation function.

[0026] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
