Description

Technical Field

[0001] This utility model relates to the field of protective equipment technology, and in particular to a helmet with a magnetic quick-release chin strap. Background Technology

[0002] Protective helmets are a type of head protection equipment widely used in motorcycle riding, mountain sports, or industrial production activities.

[0003] To provide more comprehensive facial protection, many helmets, especially full-face or combination helmets, are equipped with a chin guard, or chin shell structure, to protect the user's chin from frontal impacts. In existing technical solutions, the chin shell is usually integrally molded with the main body of the protective helmet, or connected by a more complex mechanical buckle, screw fastening or sliding rail structure.

[0004] While these connection methods ensure the overall structural strength of the helmet, they reveal significant shortcomings in daily use. When users need to temporarily drink water, make calls, or ventilate their faces, the one-piece helmet must be completely removed, which is very inconvenient. Furthermore, the chin guard, which uses complex mechanical connections, often requires cumbersome steps to disassemble, is time-consuming and labor-intensive, and may even require tools, failing to meet users' needs for quick and convenient operation.

[0005] Therefore, this utility model proposes a helmet with a magnetic quick-release chin to address the shortcomings of the prior art. Summary of the Invention

[0006] This utility model provides a helmet with a magnetic quick-release chin guard, comprising: a protective helmet, wherein a fixed base is fixed to the inner wall of the protective helmet, a fixed magnet is fixed inside the fixed base, the fixed magnet has a side for adsorption and an inner wall for locking; and a chin guard, wherein a mounting seat is provided on the chin guard.

[0007] The mounting base contains an adsorption magnet, which is used to dock and adsorb with the fixed magnet to form a primary locking.

[0008] Furthermore, a button is movably connected to the mounting base, and a docking magnet and a latch are fixedly connected to the button. The docking magnet and the latch are used to cooperate with the fixed magnet to form a two-stage locking mechanism.

[0009] In the locked state of the secondary locking mechanism, the docking magnet is adsorbed onto the side of the fixed magnet, and the buckle is engaged with the inner wall of the fixed magnet.

[0010] When the button is pressed, the button pushes the docking magnet and the latch, causing the docking magnet and the latch to separate from the fixed magnet at the same time, thereby releasing the secondary locking mechanism.

[0011] Preferably, the mounting base is also fixed with a cover, and the button is housed inside the cover. The cover provides dust protection for the button's moving mechanism, and the user operates the button through the cover, resulting in a better operating feel.

[0012] Preferably, protective shells are fixed to both sides of the chin shell, which protect the internal mounting base and button assembly from wear. A positioning post is fixed to the inner wall of the protective shell, and the mounting base is threadedly connected to the positioning post by a fixing screw. This structure ensures the stability of the mounting base and also facilitates subsequent maintenance or replacement.

[0013] Preferably, the inner wall of the protective helmet is provided with a mounting groove. A locking block is fixed to the outer wall of the chin guard. The shape and size of the locking block are adapted to the mounting groove. During installation, the locking block engages with the mounting groove to achieve initial mechanical positioning and fixation.

[0014] Preferably, as a further improvement to the aforementioned solution, a sleeve is fitted onto the outer wall of the locking block. The sleeve is used to increase the friction between the locking block and the mounting groove to prevent vibration-induced detachment. The sleeve is preferably made of an elastic rubber material to provide better damping effect.

[0015] Preferably, the protective helmet has a brim fixed to the front side. The brim extends forward from the main body of the protective helmet to shield from sunlight or rain, improving wearing comfort.

[0016] Preferably, the protective helmet has ventilation holes. These ventilation holes promote air circulation inside the helmet, preventing stuffiness, and effectively improving the wearing experience, especially during prolonged wear or in hot environments.

[0017] Preferably, the locking state of the secondary locking mechanism is achieved by the docking magnet adsorbing onto the side of the fixed magnet, using magnetic attraction to achieve rapid and automatic lateral positioning.

[0018] Preferably, the locking state of the secondary locking mechanism further includes the buckle engaging with the inner wall of the fixed magnet, providing a solid locking guarantee through mechanical engagement and preventing it from disengaging due to magnetic failure under impact.

[0019] This utility model has the following beneficial effects: 1. This utility model solves the problem of cumbersome disassembly and assembly of helmet chin guards in the prior art by setting up a magnetic quick-release structure consisting of an adsorption magnet, a docking magnet, a buckle and a button. It achieves the technical effect of quick unlocking of the chin guard with one button and convenient disassembly and installation, greatly improving the ease of use.

[0020] This invention solves the problem of unstable connection caused by vibration or accidental impact in single magnetic connection by combining a main locking mechanism consisting of an adsorption magnet and a secondary locking mechanism consisting of a docking magnet and a buckle. It achieves double locking and ensures the stability and reliability of the connection between the chin shell and the main body of the protective helmet.

[0021] This invention solves the problem of loosening or wear of internal parts caused by vibration during long-term use by setting a sleeve on the outer wall of the card block and protective shells on both sides of the chin shell. It enhances the frictional damping of the connection, protects the internal quick-release components, and improves the durability and stability of the product. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0025] Example: Please refer to Figures 1 to 5This utility model embodiment provides a helmet with a magnetic quick-release chin guard, which aims to solve the problem of existing helmets with magnetic quick-release chin guards, which include a protective helmet 11 and a chin guard 1 detachably connected to the protective helmet 11. A fixing base 10 is fixed to the inner wall of the protective helmet 11, and a fixing magnet 9 is fixed inside the fixing base 10. The fixing magnet 9 has a side for adsorption and an inner wall for locking. Figure 3 and Figure 5 As shown, a mounting base 5 is provided on the chin shell 1, and protective shells 2 are fixed on both sides of the chin shell 1. A positioning post 3 is fixed on the inner wall of the protective shell 2. The mounting base 5 is threadedly connected to the positioning post 3 by a fixing screw 4. An adsorption magnet 16 is fixed inside the mounting base 5. The adsorption magnet 16 is used to dock with the fixed magnet 9 to form a primary locking mechanism. A button 7 is also movably connected to the mounting base 5. A docking magnet 6 and a buckle 17 are fixedly connected to the button 7. The docking magnet 6 and the buckle 17 are used to cooperate with the fixed magnet 9 to form a secondary locking mechanism. In the locked state of the secondary locking mechanism, the docking magnet 6 is adsorbed on the side of the fixed magnet 9, and the buckle 17 is engaged with the inner wall of the fixed magnet 9. When the button 7 is pressed, the button 7 pushes the docking magnet 6 and the buckle 17, causing the docking magnet 6 and the buckle 17 to separate from the fixed magnet 9 at the same time, thereby releasing the secondary locking mechanism. A cover 8 is also fixed on the mounting base 5. The button 7 is housed inside the cover 8 and operated through the cover 8. To achieve initial mechanical fixation, the inner wall of the protective helmet 11 is provided with an installation groove, and the outer wall of the chin shell 1 is fixed with a locking block 12. The locking block 12 is engaged with the installation groove, and the outer wall of the locking block 12 is fitted with a sleeve 13. The sleeve 13 is used to increase the friction between the locking block 12 and the installation groove to prevent vibration from causing it to fall off. The front side of the protective helmet 11 is fixed with a brim 14, which is used to shield from sunlight or rain. The protective helmet 11 is provided with heat dissipation holes 15, which are used to promote air circulation inside the helmet and prevent stuffiness.

[0026] To solve the above-mentioned technical problems, the technical solution of this embodiment is that the helmet with magnetic quick-release chin achieves the unity of convenient operation and reliable locking through the quick-release mechanism set between the chin shell 1 and the protective helmet 11. The quick-release mechanism is mainly composed of a fixing magnet 9 fixed to one side of the protective helmet 11 and a mounting base 5 integrated into one side of the chin shell 1.

[0027] Please refer to Figure 3 , Figure 4 and Figure 5 The inner wall of the protective helmet 11 is fixed with a fixing magnet 9 by a fixing base 10. The fixing magnet 9 is the locking reference component of the quick release mechanism, which exposes the main surface for docking and adsorption, the side for adsorption, and the inner wall for locking. Mounting base 5 serves as the actuator of the quick-release mechanism. It is threadedly connected to positioning post 3 by fixing screw 4. Positioning post 3 is fixed to the inner wall of protective shell 2. Protective shell 2 is fixed to both sides of chin shell 1. The mounting base 5 has an adsorption magnet 16 fixed inside. The position of the adsorption magnet 16 is directly opposite the main surface of the fixed magnet 9, so as to generate the main adsorption force when the two are close together and realize the first-level locking. A button 7 is movably connected to the mounting base 5. The button 7 is covered with a cover 8. A mating magnet 6 and a snap fastener 17 are fixedly connected to the inner wall of the button 7. The mating magnet 6 and the snap fastener 17 together form a secondary locking mechanism. In the assembled state, the button 7 is in its naturally extended locking position. At this time, the mating magnet 6 is magnetically attracted to the side of the fixed magnet 9, while the snap fastener 17 is mechanically engaged with the inner wall of the fixed magnet 9. Through this dual action of magnetic attraction and mechanical engagement, the reliability of the secondary locking mechanism is ensured. When it is necessary to remove the chin cover 1, press the buckle cover 8 to drive the button 7 to slide inward. The button 7 drives the docking magnet 6 and the buckle 17 fixedly connected thereon to move synchronously, so that the docking magnet 6 is disengaged from the side of the fixed magnet 9 and the buckle 17 is disengaged from the inner wall of the fixed magnet 9, thereby realizing the synchronous unlocking of the secondary locking mechanism. At this time, it is only necessary to overcome the primary locking magnetic attraction between the adsorption magnet 16 and the fixed magnet 9 to remove the chin cover 1.

[0028] As a preferred embodiment, please refer to Figure 3 and Figure 5 The mounting base 5 is also fixed with a cover 8, and the button 7 is housed inside the cover 8. The outer surface of the cover 8 can be pressed by the user, thereby operating the button 7 through the cover 8. The cover 8 also serves to protect the moving mechanism of the button 7 from dust. As another preferred embodiment, please refer to Figure 3 and Figure 5 Both sides of the chin shell 1 are fixedly connected to protective shells 2. The protective shells 2 are used to protect the internal mounting base 5 and button 7 components from wear. The inner wall of the protective shell 2 is integrally formed or fixedly connected to the positioning post 3. The mounting base 5 is threaded to the positioning post 3 by fixing screws 4. This connection method ensures the installation stability and disassembly and maintenance of the mounting base 5. As another preferred embodiment, please refer to Figure 1 and Figure 3 To enhance the initial fixation and positioning of the chin shell 1 and the protective helmet 11, a mounting groove is provided on the inner wall of the protective helmet 11 at a corresponding position, and a locking block 12 is fixed on the outer wall of the chin shell 1. The shape and size of the locking block 12 are adapted to the mounting groove. During installation, the locking block 12 engages and connects in the mounting groove to achieve mechanical positioning. Based on the aforementioned implementation method, please refer to Figure 4To increase the friction between the locking block 12 and the mounting groove and prevent it from vibrating and falling off, a sleeve 13 is also fitted onto the outer wall of the locking block 12. The sleeve 13 is preferably made of an elastic material or a rubber material, which provides damping when the locking block 12 is engaged in the mounting groove. As another preferred embodiment, please refer to Figure 1 and Figure 2 To shield from sunlight or rain, a brim 14 is fixed to the front of the protective helmet 11, extending forward from the main body of the protective helmet 11. As another preferred embodiment, please refer to Figure 1 To promote air circulation inside the helmet and prevent stuffiness, the main body of the protective helmet 11 has multiple heat dissipation holes 15. For a preferred implementation of the locking scheme, please refer to... Figure 4 The locking state of the secondary locking mechanism is achieved through two coordinated methods: firstly, the docking magnet 6 is magnetically attracted to the side of the fixed magnet 9; secondly, the latch 17 is mechanically engaged with the inner wall of the fixed magnet 9. This combination of magnetic attraction and mechanical locking greatly improves the reliability of the connection.

[0029] Working principle: Before use, the mounting base 5 is threaded to the positioning post 3 fixed on the inner wall of the protective shell 2 by fixing screw 4 to complete the installation of the parts. When wearing, the clip 12 fixed on the outer wall of the chin shell 1 is engaged with the mounting groove on the inner wall of the protective helmet 11 to achieve initial wearing. The sleeve 13 on the outer wall of the clip 12 can increase the friction between the clip 12 and the protective helmet 11 to prevent it from falling off due to vibration. Then, the adsorption magnet 16 fixed on the inner wall of the mounting base 5 is engaged with the fixing magnet 9 fixed on the fixing base 10 fixed on the inner wall of the protective helmet 11. Simultaneously, the sides of the docking magnet 6 and the fixed magnet 9 are attracted, and the buckle 17 fixed on the outer wall is engaged with the inner wall of the fixed magnet 9, forming a double lock to prevent it from falling off, thus completing the combination and wearing. When disassembling, by pressing the button 7 inside the buckle cover 8, the docking magnet 6 and the buckle 17 fixed to the inner wall of the button 7 are pushed to separate from the fixed magnet 9, realizing the engagement and unlocking of the buckle 17 with the inner wall of the fixed magnet 9, and the chin shell 1 can be removed. The opening and closing can be completed without complicated operations, greatly improving the convenience of use. The protective shell 2 fixed on both sides of the chin shell 1 can resist Wear and tear protection of internal components reduces daily wear and tear, while also providing a certain mounting base. The brim 14 can be used to shield from sunlight and rain, and the ventilation holes 15 promote air circulation to prevent stuffiness and avoid discomfort caused by prolonged wear. When encountering strong impacts from the front and sides, the button 7 does not come into contact with the unlocking force of pressing forward, so that the docking magnet 6 fixed to the outer wall of the button 7 firmly fixes the buckle 17 to the inner wall of the fixing magnet 9 due to magnetic attraction, preventing the chin shell 1 from falling off, and making the chin shell 1 firmly fixed to the protective helmet 11, thereby protecting the wearer's life safety.
