Description

Technical Field

[0001] This utility model relates to the technical field of helmet components, and in particular to a snow helmet with goggles. Background Technology

[0002] In the use of snow helmets with goggles, the flip-up and locking mechanism of the goggles is a key component to ensure rapid switching of vision, stable wearing, and vibration resistance. Most existing helmets with goggles use exposed hinges, limiting grooves / protrusions, or simple toggle-type locking structures, requiring users to manually flip up or down the goggles to switch between the closed and flipped-up positions. However, this type of structure still has significant limitations in use: firstly, the mechanism is mostly located on the outside of the shell, with screws, connecting rods, or locking rings exposed, making them susceptible to damage from snow, ice water, and accidental contact with gloves, disrupting the seamless appearance and easily causing jamming; secondly, most structures only provide a few "positions" or rely on friction / spring clips for positioning, lacking a combined mechanism of automatic return or strong locking and top pressure to reduce sway. After flipping up, it is prone to shaking and displacement during gliding vibrations, and the closed end also lacks magnetic attraction or equivalent holding force, resulting in insufficient anti-restart capability.

[0003] For example, Chinese patent CN208463046U discloses a cycling helmet with a lens rotation device. The rotation gear and angle adjustment are achieved by the cooperation of the gear pressure ring, limit post and gear spring at both ends of the lens. It is an exposed gear structure. Although it can be graded in angle, it does not involve solutions such as hidden channels, automatic return or magnetic closure to improve vibration resistance and appearance integration. Moreover, the stability and sway reduction measures after flipping up are limited.

[0004] Another typical example is the goggle composite lowering mechanism disclosed in Chinese patent CN103653495A. It sets up a bushing, a rotating handle and a compression spring on the goggle arm, and works with the multi-slot and limit pin of the adjusting base plate to achieve press-to-unlock, segmented positioning and automatic lowering under overload. It belongs to the idea of ​​manual press-to-unlock + segmented slot, but the structure is mainly an external arm and handle. It does not form a combination mechanism of implicit guidance and automatic return / magnetic closing of the goggle inside the helmet shell. It also does not systematically solve the problem of top-mounted sway reduction and vibration resistance stability after flipping up.

[0005] Let's look at another example, the helmet goggle opening and closing structure disclosed in Chinese patent CN223094876U. It achieves rotatable installation and quick disassembly through the limiting channel of the lens connector and the hook / engagement part at the end of the lens, which facilitates maintenance and replacement. However, the disclosed content mainly focuses on the opening and closing and quick disassembly structure, and there is no optimization of the stability enhancement and concealment path for high vibration scenarios such as automatic return, top pressing to reduce shaking or magnetic closing in skiing.

[0006] In addition, the existing technology has the following defects: 1. The mechanism is exposed and greatly affected by snow / ice and accidental contact with gloves, resulting in poor integrated appearance; 2. It relies on manual shifting or friction positioning, lacking automatic return and closed suction retention, making it prone to shaking or self-starting during gliding; 3. The flipping path does not fully consider avoidance and concealment guidance with the brim and shell, leading to the risk of interference or jamming; 4. After flipping up to the top, it lacks pressure damping and composite locking design, making it difficult to balance stability, sealing and comfort under high-speed vibration.

[0007] This utility model was developed to address common problems in the field, such as exposed components, lack of automatic return, insufficient vibration resistance and locking, and difficulty in balancing path interference and fast stability. Utility Model Content

[0011] The concealed hinged guide mechanism includes a pivot, a rotating plate, and an arc-shaped guide groove disposed within the concealed mechanism cavity. The goggle assembly is hinged to one end of the rotating plate to form a hinge portion. The rotating plate has a hollow actuation cavity. The pivot passes through the actuation cavity and is connected to the inner wall of the concealed mechanism cavity. The goggle assembly can achieve a guiding movement from the closed position to the top position along the axis of the pivot, and the flipping path avoids the front edge of the helmet brim.

[0012] The concealed mechanism cavity is equipped with a return and locking assembly, which includes a tension spring and a locking groove.

[0013] The goggle assembly is provided with a magnetic closure component between its closed end and the helmet body. The magnetic closure component includes a magnet and a magnetic adsorption component, which are respectively disposed on the contact end surfaces of the goggle assembly and the outer wall of the rotating plate, and provide adsorption and holding force when the goggle assembly is closed. When the goggle assembly is flipped up to the top position of the helmet body, it is pressed tightly against the top of the helmet body by the pressing force of the tension spring.

[0019] Optionally, the goggle assembly includes a frame, a hinge base, and a lens. The frame is configured as a hollow observation hole, and one end face of the frame is provided with a placement groove for placing the lens. The lens is fastened in the placement groove, and the hinge base is respectively disposed on both sides of the frame.

[0020] Optionally, a torsion spring is provided in the hinge portion formed by the hinge of the goggle assembly and the rotating plate. The torsion spring is nested on the hinge rod, and the two ends of the torsion spring abut against the rotating seat and the hinge seat of the goggle assembly, respectively.

[0021] Optionally, the outer side of the helmet body is covered with a helmet shell layer, forming an integrated shape with no exposed screws or connecting rods.

[0022] Optionally, the outline of the goggle assembly is adapted to the front end of the helmet body. When the goggle assembly is in the closed state, the outer surface of the goggle assembly is flush with the outer surface of the helmet body and forms a continuous transitional overall appearance structure, and the goggle assembly and the helmet body are integrated and fitted in the closed state.

[0023] The beneficial effects achieved by this utility model are:

[0024] 1. Through the cooperation of the helmet body and the hidden hinged guide mechanism, the goggle assembly can move along the preset arc trajectory during the flipping process. Its path automatically avoids the front edge of the helmet visor, avoiding mechanical interference or scratches, ensuring that the entire helmet has the advantages of smooth movement, precise flipping angle, durable mechanism and high safety.

[0025] 2. Through the fit between the goggle assembly and the helmet body shape and the magnetic closure component, the goggle assembly forms a smooth transition with the front edge of the helmet after closing, creating an aerodynamically optimized shape. This ensures that the entire helmet has the advantages of good airtightness, excellent wind resistance, integrated vision, and vibration-resistant comfort.

[0026] 3. Through the cooperation of the return and locking components and the hidden hinge guide mechanism, the goggle assembly can automatically move smoothly along the arc-shaped guide groove during the flipping or lowering process, and automatically return to the closed position after the user releases his hand, ensuring that the entire helmet has the advantages of convenient operation, smooth flipping, reliable positioning and automatic return.

[0027] 4. Through the cooperation of the hidden mechanism cavity and the hidden hinged guide mechanism, the flipping, support and guide structure of the goggle assembly are all housed inside the helmet body, avoiding the exposure of the traditional exposed linkage or knob structure, and ensuring that the entire helmet has the advantages of integrated appearance, smooth lines, strong snow and water protection and pollution resistance.

[0028] 5. Through the cooperation of the magnetic closing component and the return and locking component, the goggle component can be automatically attracted and positioned by magnetic force when it is close to the closed position, and under the action of the spring return force, it fits tightly with the front edge of the helmet, ensuring that the entire helmet has the advantages of automatic closing, wind and snow resistance, stability and anti-shaking, and long service life.

[0029] 6. Through the comprehensive cooperation of the helmet body, goggle assembly, hidden mechanism cavity, return and locking assembly and magnetic closing component, the goggle assembly can achieve continuous and coordinated guiding, limiting, adsorption and sealing during the flipping, stopping and closing process, ensuring that the whole helmet has the advantages of good wind and snow protection performance, high structural stability, smooth and continuous flipping action, harmonious appearance and comfortable wearing.

Detailed Implementation

[0049] The following specific embodiments illustrate the implementation of this utility model. Those skilled in the art can understand the advantages and effects of this utility model from the content disclosed in this specification. This utility model can be implemented or applied through other different specific embodiments, and various details in this specification can also be modified and changed based on different viewpoints and applications without departing from the spirit of this utility model. Furthermore, the accompanying drawings of this utility model are for simple illustrative purposes only and are not depictions of actual dimensions, as stated in advance. The following embodiments will further describe the relevant technical content of this utility model in detail, but the disclosed content is not intended to limit the scope of protection of this utility model.

[0050] according to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 , Figure 10 , Figure 11 , Figure 12 , Figure 13 , Figure 14 , Figure 15 , Figure 16 and Figure 17 As shown, this embodiment provides a snow helmet with goggles. The snow helmet with goggles includes a helmet body 8 and a goggle assembly. The left and right sides of the helmet body 8 are provided with internal hidden mechanism cavities. The two ends of the goggle assembly are respectively hinged to the helmet body 8 through hidden hinge guide mechanisms provided in the hidden mechanism cavities.

[0051] The concealed hinged guide mechanism includes a pivot 16, a rotating plate 10, and an arc-shaped guide groove 9 disposed in the concealed mechanism cavity. The goggle assembly is hinged to one end of the rotating plate 10 to form a hinge part. The rotating plate 10 is provided with a hollow action cavity 12. The pivot 16 passes through the action cavity 12 and is connected to the inner wall of the concealed mechanism cavity. The goggle assembly can achieve a guiding movement from the closed position to the top position along the axis of the pivot 16, and the flipping path avoids the front edge of the helmet brim.

[0052] Through the cooperation of the helmet body 8 and the hidden hinged guide mechanism, the goggles can move along a preset arc trajectory during the flipping process. The path automatically avoids the front edge of the helmet brim, avoiding mechanical interference or scratches, ensuring that the entire helmet has the advantages of smooth movement, precise flipping angle, durable mechanism and high safety.

[0053] The concealed mechanism cavity is equipped with a return and locking assembly, which includes a tension spring 13 and a locking groove 17. One end of the tension spring 13 is nested on the pivot member 16, and the other end of the tension spring 13 abuts against the inner wall of the action cavity 12, providing an upward pressing force and a downward return force, and causing the goggle assembly to automatically return to the initial closed position after the user releases their hand; the locking groove 17 allows the goggle assembly to be reliably positioned when it reaches the upward position;

[0054] In this embodiment, the locking groove 17 is located on the side of the concealed mechanism cavity away from the goggle assembly, and the groove width of the locking groove 17 is adapted to the top of the rotating plate 10.

[0055] When the goggle assembly is flipped up and positioned at the top front of the helmet body 8, the top of the rotating plate 10 can wedge into the locking groove 17, and under the action of elasticity, the goggle assembly can be stably stopped.

[0056] The goggle assembly is provided with a magnetic closing member between its closed end and the helmet body 8. The magnetic closing member includes a magnet 15 and a magnetic adsorption component 14. The magnet 15 and the magnetic adsorption component 14 are respectively disposed on the contact end surfaces of the goggle assembly and the outer wall of the rotating plate 10, and provide adsorption and holding force when the goggle assembly is closed. When the goggle assembly is flipped up to the top position of the helmet body 8, it is pressed tightly against the top of the helmet body 8 by the pressing force of the tension spring 13.

[0057] When wearing this helmet, the user can grasp the lower edge of the goggle assembly and pull it upwards, causing the goggle assembly to smoothly flip along the arc-shaped guide groove 9. During the flipping process, both sides of the goggle assembly rotate synchronously around the pivot 16, and under the tension of the spring and the limiting effect of the guide groove, a stable arc-shaped trajectory movement is achieved. When the goggle assembly is flipped up to the top position of the helmet body 8, the tension spring 13 is stretched to its maximum, and the resulting elastic force fits against the arc surface of the helmet shell, causing the top of the goggle assembly to automatically press against the surface of the helmet shell, thereby reducing shaking and wind vibration during gliding.

[0058] When the user needs to close the goggle assembly again, simply press the upper edge of the goggle assembly or release the traction force. The tension spring 13 releases its stored energy and drives the goggle assembly to automatically return to its original position along the arc-shaped guide groove 9. The magnetic component adheres and positions itself at the moment of closure, ensuring a smooth closing action and self-locking retention of the goggle assembly. This process eliminates the need for repeated manual adjustments by the user, making it convenient and highly automated.

[0059] Through the cooperation of the return and locking components and the hidden hinge guide mechanism, the goggle assembly can automatically move smoothly along the arc-shaped guide groove 9 during the flipping or lowering process, and automatically return to the closed position after the user releases his hand, ensuring that the entire helmet has the advantages of convenient operation, smooth flipping, reliable positioning and automatic return.

[0060] Optionally, the outer side of the helmet body 8 is covered by a helmet shell layer 1, forming an integrated shape with no exposed screws or connecting rods.

[0061] like Figure 1 and Figure 2 As shown, the outer wall of the helmet body 8 is covered with the helmet shell layer 1, which isolates the external environment from the interior of the helmet body 8 and improves the overall cold protection effect of the helmet.

[0062] In addition, the arc design of the arc guide groove 9 matches the curvature of the helmet's front edge brim, allowing the goggle assembly to naturally avoid the brim during rotation, preventing interference or scratches; the hidden mechanism cavity encapsulates the pivot, spring and guide components inside the helmet shell, so that no connecting rods or screws are visible from the outside, making the helmet's overall lines smooth and highly integrated.

[0063] Through the combination of the goggle assembly and the helmet body's shape-fitting structure and magnetic closure components, the goggle assembly, after being closed, forms a smooth transition with the front edge of the helmet, creating an aerodynamically optimized shape. This ensures that the entire helmet has the advantages of good airtightness, excellent wind resistance, integrated vision, and vibration-resistant comfort.

[0064] The outer side of the concealed mechanism cavity is also provided with a sealing protective cover 7. The protective cover is fixedly connected to the helmet shell by snap-fit ​​or by screws or adhesive. While ensuring the convenience of maintenance, it can prevent snow, water vapor or dust from entering the mechanism cavity, further improving the weather resistance and service life of the mechanism.

[0065] When the goggle assembly is closed, the outer surface of the goggle assembly is flush with the front outer surface of the helmet body 8 to form a continuous and seamless overall appearance structure. This not only enhances the visual integration effect but also creates an effective airflow guiding surface, reducing air resistance and wind noise. During high-speed downhill skiing, the airflow can smoothly glide along the helmet shell and the outer surface of the goggle, significantly improving aerodynamic performance and user comfort.

[0066] Optionally, the groove width of the actuation cavity 12 is adapted to the circumference of the pivot 16, and the groove length of the actuation cavity 12 is adapted to the position of the goggle assembly flipped to the top of the helmet body 8.

[0067] Specifically, the groove width is slightly larger than the outer diameter of the pivot 16 to form a clearance fit, allowing the rotating plate 10 to rotate smoothly relative to the pivot 16 without jamming during the flipping process; preferably, the clearance value is 0.1 to 0.5 mm to balance smooth guidance and positioning accuracy. The length of the groove corresponds to the limit travel of the goggle assembly when flipped to the top position of the helmet body 8.

[0068] In other embodiments, a limiting section or buffer section is provided at its end to provide a flexible stop when the goggle assembly reaches the upward termination position, preventing excessive rotation or impact damage to the pivot 16.

[0069] The two ends of the groove of the action cavity 12 correspond to the closed position and the top pressing position of the goggle assembly, respectively. During the flipping process, the sliding end face of the rotating plate 10 moves along a preset arc trajectory under the guidance of the groove wall, thereby ensuring that the goggle maintains balance and symmetry throughout the flipping path and improving the smoothness and stability of the action.

[0070] The structural design of the hidden hinged guide mechanism ensures that the goggle assembly has clear movement boundaries and a mechanical buffer zone during the flipping motion, avoiding shaking, jamming, or inaccurate positioning caused by excessive flipping angle or accumulation of structural tolerances.

[0071] In addition, through the cooperation of the hidden mechanism cavity and the hidden hinged guide mechanism, the flipping, support and guide structure of the goggles are all housed inside the helmet body 8, avoiding the exposure of traditional exposed linkage or knob structure, and ensuring that the entire helmet has the advantages of integrated appearance, smooth lines, strong snow and water protection and pollution resistance.

[0072] Optionally, the goggle assembly includes a frame 5, a hinge base 19, and a lens 3. The frame 5 is configured with a hollow observation hole 18, and one end face of the frame 5 is provided with a placement groove 6 for placing the lens 3. The lens 3 is fastened in the placement groove 6. The hinge base 19 is respectively disposed on both sides of the frame 5 for forming a rotatable connection with the hinge part of the rotating plate 10.

[0073] like Figure 5 As shown, the edge of the placement groove 6 is provided with a locking hole 11, and the end face of the lens 3 near the placement groove 6 is provided with a locking protrusion; when the lens 3 is assembled in the placement groove 6, the locking protrusion and the locking hole 11 are mutually locked and locked, so that the lens 3 can be completely hidden and assembled at the front end of the frame 5.

[0074] A magnetic closing component is provided between the closed end of the goggle assembly and the helmet body 8. The magnetic closing component includes a magnet 15 and a magnetic adsorption component 14. The magnet 15 is embedded in the frame 5 of the goggle.

[0075] In addition, the goggle assembly also includes a connecting base 4, which is symmetrically arranged on both sides of the frame 5 and detachably snapped into the frame 5; for example Figure 16 As shown, the connecting seat 4 is provided with at least two connecting tongues 24, and the frame 5 is provided with at least two snap-fit ​​holes. The connecting tongues 24 and the snap-fit ​​holes are arranged opposite to each other, so that when the connecting seat 4 is assembled on the wide body, they can be mutually limited and snap-fitted to form a complete frame 5 structure.

[0076] Meanwhile, the connecting seat 4 has a placement hole on the side facing the front shell of the helmet body 8, and the magnet 15 is hidden and snapped into the placement hole.

[0077] A magnetic closing component is provided between the closed end of the goggle assembly and the helmet body 8. The magnetic closing component includes a magnet 15 and a magnetic adsorption component 14. The magnet 15 is embedded in the frame 5 of the goggle.

[0078] In this embodiment, the rotating plate 10 is provided with a limiting seat 23 on the side facing the goggle assembly. The limiting seat 23 is provided with a slot, and the magnetic adsorption member 14 is disposed in the slot. The magnet 15 and the magnetic adsorption member 14 form a magnetic adsorption fixation when the goggle assembly is closed.

[0079] In this embodiment, the magnet 15 and the magnetic adsorption member 14 are arranged opposite each other and are at the same height when closed, so that the two magnetically attract each other when the goggle assembly is closed to the preset position, thereby achieving automatic positioning and holding.

[0080] Simultaneously, when the goggle assembly approaches the closed position under the action of the return spring, an attractive force is generated between the magnet 15 and the magnetic adsorption component 14, thereby achieving automatic adsorption and positioning, allowing the goggle assembly to naturally close to a fully closed state after being released. A 0.2–0.5 mm adsorption gap is preferably reserved between the magnet 15 and the adsorption component to avoid direct collision and extend the service life of the adsorption structure.

[0081] The magnet 15 can be a neodymium iron boron permanent magnet, a ferrite magnet, or a composite magnet with an anti-corrosion coating. The magnetic adsorption component 14 can be an iron-nickel alloy component or a stainless steel magnetic sheet to ensure stable magnetic attraction even in low-temperature and humid environments. The magnetic closure component not only enables the goggle assembly to automatically attract and securely close.

[0082] In another embodiment, the magnetic component can also be designed as a replaceable modular structure and fixed to the connecting seat 4 and the slot by screws, buckles or adhesives, respectively, so as to facilitate later maintenance, replacement or adjustment of magnetic force to meet the needs of different users for closing feel and adsorption strength.

[0083] Optionally, the outline of the goggle assembly is adapted to the front end of the helmet body 8. When the goggle is closed, the outer surface of the goggle assembly is flush with the outer surface of the helmet body 8 to form a continuous transitional overall appearance structure. In the closed state, the goggle assembly and the helmet body 8 are integrated and fitted together, improving the sealing and windproof performance and the overall visual integrity.

[0084] In this embodiment, through the structural design of the magnetic closure component, when the goggle assembly is closed, the outer arc surface of the goggle frame 5 and the front edge shell of the helmet body 8 form a continuous curved transition. This not only eliminates the step gap between the goggle assembly and the helmet in the traditional structure, improving windproof sealing performance and snow penetration resistance, but also optimizes airflow guidance, allowing air to flow smoothly along the helmet shell, significantly reducing wind resistance and wind noise, and improving stability and wearing comfort during skiing.

[0085] In this embodiment, the magnetic closing component and the return and locking component work together to allow the goggle assembly to be automatically magnetically attracted and positioned when it approaches the closed position. Under the return force of the spring, it fits tightly against the front edge of the helmet, ensuring that the entire helmet has the advantages of automatic closing, wind and snow protection, stability and anti-shaking, and long service life.

[0086] Optionally, a flexible sealing gasket is provided on the inner surface of the helmet body 8 at the closed contact area of ​​the goggle assembly to enhance the closure and sealing performance and snow resistance.

[0087] Specifically, the flexible sealing pad is arranged in a ring along the front edge of the helmet body 8, forming a continuous sealing ring corresponding to the contact area after the goggle assembly is closed. The flexible sealing pad can be made of silicone rubber, thermoplastic elastomer (TPE), foamed EVA, or other low-temperature resistant elastic materials, and has good resilience and cold resistance, remaining soft and conforming in environments ranging from -30℃ to -40℃.

[0088] One side of the flexible sealing pad is fixed to the helmet body 8 by bonding, slot embedding or screw limiting, while the other side forms a flexible lip structure. When the goggle assembly is closed, it is subjected to the combined action of magnetic attraction and spring return force to seal and fit with the lower edge of the goggle assembly, thereby effectively blocking cold air, snow particles and water vapor from entering the helmet.

[0089] Furthermore, the flexible sealing gasket also acts as a buffer and vibration damper during closed contact, absorbing the impact force of the goggle assembly at the moment of closure, preventing the lens 3 from colliding hard with the helmet, and extending the component's lifespan. Its material surface can be provided with micro-protrusions or annular waterproof lips to improve the friction and sealing stability of the contact surface.

[0090] When the goggle assembly is closed, the sealing gasket, magnetic closure component, and the outer surface of the goggle assembly together form a triple protective structure, achieving a comprehensive sealing effect of mechanical limiting, magnetic self-locking, and elastic sealing, so that the helmet can remain dry and stable in temperature even when gliding at high speed or in windy and snowy environments.

[0091] Optionally, the concealed mechanism cavity is provided with a sealing protective cover 7. The sealing protective cover 7 is detachably fastened or embedded in the concealed mechanism cavity and is connected to the helmet body 8 by means of screw connection, snap locking, groove fitting, or adhesive bonding to form a seal and protection for the concealed mechanism cavity.

[0092] Specifically, the sealing cover 7 is correspondingly installed at the hidden mechanism cavity openings on both sides of the helmet body 8. The outer contour of the sealing cover 7 matches the curved surface of the helmet body 8 shell, so that the sealing cover 7 is flush with the outer surface of the helmet after installation, ensuring the integrity and integration of the overall appearance.

[0093] The sealing protective cover 7 has a sealing lip or annular flange around its circumference. The sealing lip forms an elastic fit with the corresponding edge of the hidden mechanism cavity opening to prevent the infiltration of snow, dust and cold air. Preferably, a flexible sealing ring or waterproof strip can be provided at the lip to further improve the protection level.

[0094] The sealing and protective cover 7 can be made of high-toughness ABS plastic, polycarbonate (PC), glass fiber reinforced nylon or aluminum alloy sheet material, and its surface can be treated with anti-scratch coating or hydrophobic coating to improve wear resistance and stain resistance.

[0095] For ease of maintenance, the sealing cover 7 can be designed as a detachable structure, and can be repeatedly connected to the helmet body 8 via screws, clips, or sliding locks. Users can remove the sealing cover 7 for maintenance or replacement to lubricate or inspect the internal pivot 16, springs, and guide grooves. After reinstallation, the sealing cover 7 is reset via a self-locking structure or elastic snap-fit ​​mechanism, ensuring a secure installation and reliable seal.

[0096] In other embodiments, a water channel or drainage hole may be provided between the sealing protective cover 7 and the hidden mechanism cavity to draw out water vapor or condensate when the snow melts, preventing water accumulation and freezing in the cavity from affecting the normal operation of the goggle assembly flipping mechanism, thereby improving the reliability and lifespan of the helmet in low temperature and humid environments.

[0097] The sealed protective cover 7 not only provides snowproof, waterproof, dustproof and impact-resistant protection for the concealed mechanism cavity, but also has the dual functions of being removable for maintenance and having an integrated appearance.

[0098] When the goggle assembly flips up or closes frequently during skiing, the protective cover effectively prevents snow water from entering the cavity, causing the spring to rust or the movement to become stuck. At the same time, its flush shape with the helmet shell further enhances the overall aerodynamic performance and visual appeal of the helmet.

[0099] Optionally, a torsion spring 22 is provided in the hinge portion formed by the hinge of the goggle assembly and the rotating plate 10. The torsion spring 22 is nested on the hinge rod 21, and both ends of the torsion spring 22 abut against the rotating seat 20 and the hinge seat 19 of the goggle assembly, respectively, to provide elastic auxiliary force during the flipping or closing of the goggle assembly. By cooperating with the rotational force of the torsion spring 22 and the linear tension of the tension spring 13 in the concealed mechanism cavity, a pressing force can be generated when the goggle assembly is flipped to the top, and a return force can be generated when it is closed, thus realizing a smooth elastic flipping and automatic closing function.

[0100] Optionally, the rotating plate 10 is hinged to the goggle assembly at one end and is provided with a rotating seat 20. The rotating seat 20 has a U-shaped cross section along the width direction and is provided with limiting holes 25 on both inner walls.

[0101] Specifically, the rotating base 20 is fixedly mounted at the end of the rotating plate 10, with its two arms extending outward in a U-shape to provide sufficient installation space and rotation angle within the limited cavity space. The open end of the rotating base 20 is positioned opposite to the hinge base 19 of the goggle assembly, and the two are rotatably connected by the hinge rod 21, thereby forming the rotation fulcrum of the goggle assembly.

[0102] The limiting hole 25 is located in the middle of the rotating seat 20 and is used to install the hinge rod 21. The torsion spring 22 is integrally embedded in the hinge rod 21, and one end of the torsion spring 22 abuts against the hinge seat 19 of the goggle assembly, while the other end of the torsion spring 22 abuts against the inner wall of the rotating seat 20. When the goggle assembly is flipped up, the torsion spring 22 is torsionally stored. When the goggle is released or returned to its original position, the torsion spring 22 releases its elastic potential energy, providing the goggle with a return force and a clamping force.

[0103] The torsion spring 22 also works in conjunction with the magnetic closure member and the tension spring 13 to provide anti-sway support during high-speed vibrations in skiing, preventing the goggle assembly from loosening or accidentally opening.

[0104] The limiting hole 25 can also serve as a limiting structure for the flipping angle. Its hole wall can form a mechanical stop together with the mating surface on the hinge rod 21 and the rotating plate 10 to prevent the flipping angle of the goggle assembly from exceeding the set range, thereby avoiding jamming or damage caused by overtravel of the mechanism.

[0105] The rotating base 20, the hinge base 19, and the torsion spring 22 form a triangular mechanical structure in space: the rotating base 20 provides support and a limiting reference, the hinge base 19 provides a rotation pivot, and the torsion spring 22 provides elastic rotational force. The three work together to ensure that the goggle assembly has a stable force path and flexible rebound characteristics during the upward and downward movement.

[0106] Preferably, the rotating seat 20 and the rotating plate 10 can be integrally injection molded or fixed by metal riveting. The material can be high-strength nylon, aluminum alloy, or carbon fiber reinforced composite material to ensure sufficient strength and toughness even under repeated turning and low-temperature environments. The inner wall of the limiting hole 25 can be provided with reinforcing ribs or metal bushings to improve the wear resistance and deformation resistance of the hole.

[0107] In this embodiment, the helmet body is also provided with ear protector blocks 2. The ear protector blocks 2 are symmetrically arranged at the ear positions of the helmet body and are connected to the helmet body by means of screw connection, buckle locking and groove.

[0108] In addition, in this embodiment, through the comprehensive cooperation of the helmet body 8, goggle assembly, hidden mechanism cavity, return and locking assembly and magnetic closing component, the goggle can achieve continuous synergistic effects of guidance, limiting, adsorption and sealing during the flipping, stopping and closing process, ensuring that the entire helmet has the advantages of good wind and snow protection performance, high structural stability, smooth and continuous flipping action, harmonious appearance and comfortable wearing.

[0109] The above-disclosed content is only a preferred and feasible embodiment of the present utility model, and is not intended to limit the protection scope of the present utility model. Therefore, all equivalent technical changes made based on the contents of the present utility model specification and drawings are included within the protection scope of the present utility model. Furthermore, the elements therein can be updated as technology develops.
