Description

Technical Field

[0001] This utility model relates to the field of helmet goggles technology, specifically a quick-release adjustable helmet goggle. Background Technology

[0002] In existing technologies, the fixing methods and adjustment functions of helmet visors have significant limitations. Traditional visors often use a single fixing structure, such as connecting to the helmet via screws or clips, resulting in cumbersome assembly and disassembly processes, making quick replacement or adjustment difficult, especially in emergencies. Furthermore, the adjustment mechanisms of existing visors typically require complex operations, such as rotating screws or pressing buttons, and lack sufficient adjustment precision to meet the diverse needs of different wearers' head sizes or usage scenarios. For example, some visors only support limited tilt adjustments, failing to adapt to the field of vision requirements during strenuous activity or under varying lighting conditions.

[0003] Furthermore, the elastic band design of existing goggles generally suffers from problems such as being prone to loosening or being too tight. Traditional elastic bands are fixed by simple buckles or knots, and after prolonged use, the tightness is easily reduced due to material fatigue, affecting wearing comfort and safety. Although some designs use a sliding adjustment structure, they lack an effective self-locking mechanism and are easily malfunctioning due to external pulling. In addition, the connection between goggles and frames is mostly a rigid embedding, lacking flexibility, which may cause the lens to break or fall off due to impact, posing a safety hazard.

[0004] With the increasing demand for multi-functional helmets, users are placing higher demands on the compatibility of goggles. For example, the same helmet needs to be compatible with goggles with different functions (such as clear lenses, filter lenses, or laser protection goggles). However, current technologies have poor compatibility between goggles and frames, requiring the entire frame to be disassembled or complex tools to be used when changing them, resulting in low operational efficiency. At the same time, existing goggles struggle to balance field of vision and protective performance. For instance, in bright light environments, frequent lens switching is necessary, but traditional structures cannot achieve rapid switching, impacting the user experience. Utility Model Content

[0005] The purpose of this invention is to provide a quick-release adjustable helmet goggle.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a quick-release adjustable helmet visor, wherein the helmet visor forms a modular structure through a combination design of a frame, visor, hook, adjustment buckle, and elastic band. The frame serves as the main support frame, and its inner groove matches the visor to ensure installation stability, while the outer hook and adjustment buckle work together to achieve dynamic adjustment of the elastic band. The elastic band passes through the through-hole of the adjustment buckle to form a closed-loop structure, allowing for length adaptation through sliding adjustment to suit different head circumferences. This structure reduces reliance on complex tools and improves assembly efficiency through a mechanical linkage design. The modular design simplifies the connection structure between the visor and the helmet, the cooperation between the hook and adjustment buckle enhances system stability, and the closed-loop adjustment mechanism of the elastic band avoids the problem of easy loosening of traditional buckles, while also reducing maintenance costs.

[0007] Furthermore, the goggles are fitted into a groove inside the frame via a snap-fit ​​or sliding mechanism, their contour perfectly matching the curved inner edge of the frame. The groove can be fitted with a flexible clip or guide groove to ensure a tight fit between the goggles and the frame after installation. This design allows the goggles to be adjusted vertically or horizontally to accommodate differences in facial contours, such as nose bridge height or eye socket depth. The sliding adjustment function enhances the goggles' adaptability, the matching of the curved inner edge with the goggles' contour reduces installation gaps and prevents wobbling, while the snap-fit ​​structure simplifies the assembly and disassembly process, facilitating quick replacement of lenses with different functions (such as clear lenses and anti-fog lenses).

[0008] Furthermore, hooks are symmetrically distributed on both sides of the outer end of the goggle frame, with the hook-shaped part of each hook curving outward to form a "C"-shaped structure. The inner side of the hook-shaped part has anti-slip textures that engage with the protrusions or grooves on the edge of the goggles to achieve a two-way locking mechanism. During installation, the goggles slide in through the open end of the hook, and the hook-shaped part automatically springs back and locks in place; during removal, pressing the hook-shaped part releases the goggles. The symmetrical hook design distributes the force on the goggles, avoiding deformation caused by single-point load, while the outward-curving hook-shaped part increases the contact area, improving impact resistance. Simultaneously, the two-way locking mechanism ensures that the goggles are not easily dislodged during vigorous activity.

[0009] Furthermore, the adjusting buckle is fixedly connected to the inner end of the hook, and its through-hole inner wall has a smooth guide surface. After the elastic band passes through the through-hole, its effective length can be adjusted by sliding. The narrow section or constricted part of the through-hole forms a natural locking point. When the elastic band slides to the target position, additional pulling force is required to pass through the locking point, thus achieving the self-locking function. The adjusting buckle can be fixed by injection molding or screw fastening to ensure the connection strength with the hook. The sliding adjustment mechanism combined with the self-locking design solves the problem of traditional elastic bands easily slipping or loosening. The narrow section locking point achieves position locking through frictional resistance, making operation simple and highly reliable, suitable for rapid adjustment in dynamic riding environments.

[0010] Furthermore, the roughening treatment of the inner surface of the hook (such as laser etching or frosting) significantly increases the coefficient of friction, creating multi-point engagement with the edge of the goggles. The roughened area can be designed as parallel stripes or a grid structure, which does not affect the appearance but enhances the anti-slip performance. The increased coefficient of friction effectively prevents the goggles from shifting during high-speed airflow or head movement. The roughened structure can be achieved without additional materials, reducing manufacturing costs and extending the lifespan of the hook.

[0011] Furthermore, the elastic band features a closed loop structure, with both ends secured to the adjustment buckles on either side by stitching or snaps. The loop is made of a highly elastic material (such as silicone or polyurethane), and its width matches the through-holes of the adjustment buckles to avoid localized stress concentration. The loop design ensures even force distribution on the elastic band, reducing pressure on the head. The loop structure eliminates the friction discomfort caused by exposed ends of traditional elastic bands, while the closed design enhances the overall aesthetics. The choice of elastic material balances comfort and durability, making it suitable for extended wear.

[0012] Furthermore, both ends of the elastic band are secured to the adjustment buckle via snaps or threads, with anti-slip structures (such as barbs or limit blocks) at the connection points. The length of the loop band can be infinitely adjusted via the sliding adjustment buckle, covering different head circumferences (e.g., 50cm to 65cm). Snaps or threads ensure reliable securing of the elastic band, the anti-slip structure prevents accidental loosening, the infinitely adjustable function meets individual needs, and the combination of the loop band and adjustment buckle simplifies the wearing process, enhancing the user experience.

[0013] This utility model provides a quick-release adjustable helmet goggle, which has the following beneficial effects:

[0014] This invention, through innovative structural design, significantly improves the quick-release capability, adjustment flexibility, and wearing comfort of helmet goggles. The locking or sliding mechanism between the inner groove of the frame and the goggles enables rapid installation and removal of the goggles, allowing for tool-free replacement and adaptability to various protection needs. Symmetrically distributed hooks on both sides of the outer frame, combined with outwardly curved hooks, enhance the stability of the goggle installation while simplifying the operation, allowing for easy fixing or releasing with one hand.

[0015] The design of the adjustment buckle and elastic band optimizes wearing comfort. The elastic band slides through a through-hole to adjust the effective length, offering simple operation and a wide adjustment range to accommodate different head circumferences. The guide bevel at the through-hole entrance reduces resistance when inserting the elastic band, while the self-locking anti-loosening structure in the narrow internal section or constriction ensures that the elastic band will not easily slip after adjustment, avoiding the risk of visual field deviation or goggles falling off due to loosening. The roughened inner surface of the hook-shaped part further enhances friction, strengthening the connection between the goggles and the frame, maintaining reliable fixation even during vigorous activity.

[0016] Furthermore, the elastic band adopts a loop structure, with both ends fixed to the adjustment buckles, forming a closed-loop design. This not only simplifies the installation process but also improves the overall durability of the structure. This design effectively distributes the pressure of the goggles on the head, reducing the pressure felt during prolonged wear. Simultaneously, a self-locking mechanism maintains constant tension in the elastic band, ensuring the goggles always conform to the facial contours, enhancing protective performance and user comfort. In summary, this invention, through its modular and adjustable structural design, overcomes the shortcomings of traditional goggles in terms of assembly / disassembly efficiency, adjustment precision, and wearing comfort, making it suitable for various complex environments and application scenarios.

When the following description relates to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this disclosure.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the 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 scope of protection of the present utility model.

[0023] How to use

[0024] Step 1: Installing the goggles

[0025] 1. Take out the goggles 2 and align the temples or edge slots with the corresponding positions of the grooves on the inner side of the frame 1. Push the goggles 2 into the frame 1 along the groove direction by pressing or sliding until they are fully embedded. At this time, the curved contour of the goggles 2 fits tightly with the inner edge of the frame 1, ensuring an unobstructed field of vision.

[0026] 2. Unfold the hook-shaped parts of the hooks 3 on both sides of the goggles 2 outwards, so that the openings of the hook-shaped parts face outwards. Insert the hook-shaped parts of the hooks 3 into the corresponding fixing positions on the helmet, and use the roughening treatment of the inner surface of the hook-shaped parts, such as the frosted texture, to form a frictional engagement with the helmet slots to initially fix the goggles 2.

[0027] Step 2: Adjusting the elastic band

[0028] 1. Hold the adjustment buckles 4 on both sides with both hands and gently pull the elastic band 5 outwards to allow it to slide out of the through holes of the adjustment buckles 4, thus extending the effective length of the elastic band 5. When adjusting, observe the fit between the elastic band 5 and the head, ensuring that there is still about two fingers' width of slack after the elastic band 5 is wrapped around the head.

[0029] 2. When the elastic band 5 slides to the target position, press inward at the through-hole entrance of the adjusting buckle 4. Utilize the self-locking anti-loosening structure of the narrow section inside the through-hole or the constricted end to engage the elastic band 5 at the locking point. At this point, additional pulling force is required to move the elastic band 5, thus completing the length locking.

[0030] Step 3: Wearing and Secondary Fixation

[0031] 1. Place the helmet on your head and adjust it to a comfortable angle. Ensure that the goggles 2 and helmet are under synchronized force by engaging the outward-curving hook of the hook 3 with the helmet's fixing point. When wearing the helmet, you can fine-tune the fit between the goggles 2 and your face by pressing the hook of the hook 3 with one hand.

[0032] 2. After wearing, check the locking status of the elastic band 5: gently pull the end of the elastic band 5. If it cannot move, it means that the self-locking is effective; if it can slide, press the adjustment buckle 4 again and adjust it to the locking point position.

[0033] Step 4: Disassembling the goggles

[0034] 1. Press down on the hook-shaped part of the hook 3 with one hand to release its friction engagement with the helmet fixing position. Hold both sides of the goggles 2 with both hands and push the goggles 2 smoothly out along the groove of the frame 1, avoiding tilting or uneven force that could damage the buckle.

[0035] 2. If you need to change the lens function, such as switching between clear lenses and anti-fog lenses, repeat steps one to three and install the goggles 2 with the appropriate lenses.

[0036] Precautions

[0037] When adjusting the elastic band, avoid overstretching to prevent fatigue failure of the elastic material.

[0038] After disassembling the goggles, avoid direct contact between the lenses and hard objects, and store them in a dedicated protective case.

[0039] Regularly check the wear of the roughened area of ​​the hook 3. If the coefficient of friction decreases, replace it in time.

[0040] Operational advantages: This method achieves quick assembly and disassembly of goggles through modular design. The synergistic effect of hook 3 and adjustment buckle 4 ensures wearing stability, while the self-locking mechanism of elastic band 5 avoids the problem of traditional buckles easily loosening. The closed-loop structure of the circular elastic band 5 distributes head pressure, improving comfort during long-term wear, while also being compatible with the lens switching needs of multiple scenarios.

[0041] Example 1: Sliding adjustment and locking structure for goggles

[0042] This embodiment optimizes the detachable and sliding adjustment functions of the goggles. The inner groove of the frame features an arc-shaped design that perfectly matches the arc-shaped contour of the goggles' edge. The groove contains a spring-loaded buckle and a guide groove. During installation, the goggles are pushed in along the groove direction via the temples or edge grooves, and the spring-loaded buckle automatically springs back to lock. During removal, pressing the buckle releases the goggles. The sliding adjustment function is achieved through the guide groove at the bottom of the groove, allowing the goggles to slide back and forth along the groove to fit different wearers' facial contours. Hooks are symmetrically distributed at the outer end of the frame, with the hook-shaped parts curved outwards and featuring anti-slip textures inside. When engaged with the helmet's fixing position, they form a two-way lock, preventing the goggles from shifting during vigorous activity.

[0043] Example 2: Elastic band self-locking adjustment and ring-shaped closing structure

[0044] This embodiment focuses on the elastic band adjustment mechanism. The adjustment buckle is fixedly connected to the inside of the hook, and the inner wall of the through hole has a smooth guide surface and a narrow section for closing. The elastic band is an elastic ring band, with both ends fixed to the adjustment buckle. During sliding adjustment, it moves smoothly through the guide surface. After reaching the target position, the narrow section forms a natural locking point, requiring additional pulling force to slide, thus achieving self-locking and preventing loosening. The inner surface of the hook-shaped part of the hook is roughened with a frosted process to increase the coefficient of friction with the goggles and ensure a stable connection. When worn, the ring elastic band evenly distributes pressure, reducing pressure on the head, while the self-locking mechanism avoids the problem of traditional buckles easily loosening.

[0045] Example 3: Modular quick-release and multi-scene lens switching

[0046] This embodiment incorporates a modular design. The frame and goggles are separate units. The goggles are inserted into the frame's groove via slots or sliding mechanisms. The grooves contain limiting blocks and stops to prevent the lenses from tilting or falling out. Hooks are symmetrically distributed on both sides of the frame, with an unlocking button at the end of each hook. Pressing this button allows for quick removal of the goggles. Multi-scene lens switching is supported, such as clear lenses, filter lenses, and anti-fog lenses. The lens edges have protrusions that match the grooves; simply aligning them with the slots during installation completes the fixation. An adjustment buckle and elastic band work together to achieve stepless length adjustment, accommodating different head circumferences. Operation is simple and tool-free.

[0047] Example 4: Enhanced Hook Anti-Loosening and Dynamic Stability

[0048] This embodiment improves the hook structure. The hook is made of high-strength alloy material, and the inner surface of the hook-shaped part is roughened with parallel stripes or a grid pattern to increase the friction with the helmet fixing point. The symmetrically distributed hooks create mechanical balance during installation, distributing the force on the goggles and avoiding deformation caused by single-point load. The end of the hook has an elastic limiting piece, forming a double lock with the helmet slot to prevent the goggles from loosening due to vibration or impact during riding. The combination of the adjustment buckle and the elastic band further enhances stability, ensuring that the goggles always fit snugly against the face.

[0049] Example 5: Composite Adjustment and Rapid Wearing System

[0050] This embodiment forms a composite adjustment system. The adjustment buckle through-hole adopts a segmented design, with a smooth guide area at the front and a narrow locking area at the rear. After the elastic band slides to the locking area, it is locked with the assistance of a spring plate. The inner surface of the hook-shaped part is embedded with a micro-protrusion array, forming an interlocking structure with the groove on the edge of the goggles, improving anti-slip performance. When wearing, the length of the elastic band can be adjusted by operating the adjustment buckle with one hand. At the same time, the elastic limiting piece of the hook automatically engages with the helmet fixing position, realizing quick wearing and stable fixation of the goggles. When disassembling, pressing the unlock button releases the hook, and the goggles are smoothly removed along the groove direction.
