Description

Technical Field

[0001] This invention relates to the field of goggle technology, specifically to a goggle with a detachable flexible element. Background Technology

[0002] During outdoor sports or cycling activities, people often need to wear goggles to protect their eyes from external factors such as ultraviolet rays, dust, and air currents. However, existing goggles have some problems in use.

[0003] On the one hand, although goggles can block ultraviolet rays and airflow, after wearing them for a long time, the inside of the goggles can easily become hot and humid due to sweat, causing discomfort to the wearer. It may even cause the inner lens to fog up, affecting vision and causing inconvenience to the wearer.

[0004] On the other hand, when ventilation is required, the structural design of goggles often fails to facilitate rapid and effective air exchange between the inside and outside, while also failing to adequately prevent external airflow from blowing directly into the eyes, causing discomfort. These issues limit the effectiveness and wearing experience of goggles during outdoor activities. In summary, existing goggles have numerous problems in terms of wearing comfort, ventilation, and structural design, which limit their effectiveness and wearing experience during outdoor activities. Therefore, a goggle design that effectively addresses these issues is needed to improve wearer comfort and the overall practicality of the goggles. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a goggle with detachable flexible components, which solves the problems mentioned in the background art, such as the tendency of existing goggles to become stuffy and uncomfortable to wear, and the unsatisfactory ventilation effect.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a goggle with a detachable flexible element, comprising: The securing strap, made of elastic material, is used to secure the goggles when worn. Also includes: The frame assembly is fixedly connected to both ends of the fixing strap and is used to fix the internal components of the goggles; A lens assembly, installed inside the frame assembly, is used to provide eye protection when worn; A ventilation assembly, located at the top of the frame assembly, is used to control the opening and closing of the ventilation channels of the frame assembly; There are two telescopic components, which are installed inside both ends of the frame component and connected to the ventilation component.

[0007] Preferably, the frame assembly includes a goggle body with a slot on its inner surface. The goggle body is made of rubber, and one side of the goggle body conforms to the contour of the user's face. Rotary shafts are embedded at both ends of the goggle body, and these shafts are inserted into the center of a lever. The lever is rotatably connected to the shaft, and one end of the lever has an L-shaped structure. Ventilation slots are provided on the top surface of the goggle body, and these slots are distributed in an arc-shaped, evenly spaced pattern. The rubber goggle body has good flexibility and elasticity, allowing it to closely conform to the user's facial contours, ensuring stability and comfort during wear. The slots on its inner surface, combined with the elastic deformation characteristics of the rubber material, enable convenient removal and installation of the inner lens. When the inner lens needs to be removed, only appropriate external force needs to be applied to cause a slight deformation of the goggle body to easily remove the inner lens. During installation, the elasticity of the rubber is also used to embed the inner lens into the slot, making the operation simple and convenient.

[0008] Preferably, the inner sides of both ends of the goggle body are provided with grooves, and a first magnetic strip is embedded in the inner groove of both ends of the goggle body. The first magnetic strip corresponds to two second magnetic strips, and the second magnetic strips are magnetically connected to the first magnetic strips. By embedding the first magnetic strip in the inner groove of both ends of the goggle body and making it magnetically connected to the second magnetic strips at both ends of the outer lens, the rapid positioning and stable installation of the outer lens is achieved. This magnetic structure facilitates the fixation of the outer lens and improves the convenience of use.

[0009] Preferably, the lens assembly includes an outer lens, with grooves embedded on the inner sides of both ends of the outer lens, and second magnetic strips embedded in the grooves at both ends of the outer lens. A connector is provided on the inner side of the outer lens, and an inner lens is provided at the other end of the connector. The inner lens is embedded in a slot, and ventilation micropores are evenly distributed on the bottom edge of the inner lens. The evenly distributed ventilation micropores on the bottom edge of the inner lens can effectively promote air circulation inside the goggles, reduce moisture accumulation, and inhibit fogging of the inner lens, thereby improving wearing comfort and visual clarity.

[0010] Preferably, the inner lens is made of transparent material, and the outer lens has an anti-UV coating. The outer lens and the connector are bonded together, and the other end of the connector is bonded to the inner lens. The connector has a multi-folded structure for expansion and contraction, and is made of rubber with permeable micropores. The transparent inner lens ensures good visual performance, while the anti-UV coating on the outer lens effectively blocks UV rays from harming the eyes. The bonded connection between the outer lens and the connector, and between the connector and the inner lens, ensures the structural stability of the lens assembly. The rubber connector with a multi-folded structure provides good flexibility, offering cushioning and adjustment space between the outer and inner lenses. Simultaneously, the permeable micropores on the connector surface further enhance airflow, helping to reduce moisture buildup inside the goggles, preventing fogging of the inner lens, and thus improving wearing comfort and visual clarity.

[0011] Preferably, the ventilation component includes a bimetallic strip with an arc-shaped structure, which is attached to the surface of the ventilation slot. The bimetallic strip consists of two layers of thin metal sheets, namely copper and iron. Rivets are fixed at both ends of the bimetallic strip, and the middle part of the bimetallic strip is connected to the top of the goggle body via a connecting bolt. The bimetallic strip, composed of two layers of thin metal sheets (copper and iron), has different coefficients of thermal expansion. When the ambient temperature rises, the bimetallic strip bends and deforms, automatically opening the ventilation slot to allow air circulation between the inside and outside of the goggles, reducing internal temperature and humidity. This automatic adjustment function requires no manual operation and can automatically adjust the ventilation state according to actual environmental changes, improving wearing comfort.

[0012] Preferably, the ventilation component includes two connecting pieces, each connected to one end of a bimetallic strip. One end of each connecting piece has a telescopic tube inserted into the goggle body. The telescopic tube has a hollow interior and a slotted outer wall, which slides in contact with the goggle body. The connecting pieces, connected to both ends of the bimetallic strip, convert the thermal expansion and contraction of the bimetallic strip into the vertical movement of the telescopic tube. The telescopic tube's hollow interior and slotted outer wall design allow it to move upwards when the bimetallic strip bends due to temperature rise, exposing the slots. External airflow can then enter the goggle, achieving forced ventilation, effectively reducing internal temperature and humidity, and suppressing fogging of the inner lens.

[0013] Preferably, one end of the connecting piece has a groove, and the inside of the groove slides in contact with the outer wall of the telescopic tube. Two limiting rings are fitted onto the outside of the telescopic tube, located above and below the connecting piece, respectively. A groove on the surface of the telescopic tube slides in connection with a limiting block, which is embedded inside the goggle body. The opening of the groove on the surface of the telescopic tube faces the surface of the inner lens. The sliding contact between the groove at one end of the connecting piece and the outer wall of the telescopic tube, along with the two limiting rings located above and below the connecting piece, together constitute a stable sliding limiting structure. This structure ensures the smooth up-and-down movement of the telescopic tube driven by the deformation of the bimetallic strip, preventing it from shifting or jamming during movement. The sliding connection between the groove on the surface of the telescopic tube and the limiting block, and the embedding of the limiting block inside the goggle body, further enhance the stability and accuracy of the telescopic tube's movement. Furthermore, the opening of the groove on the surface of the telescopic tube facing the surface of the inner lens allows external airflow to directly blow onto the inner lens through the groove, effectively suppressing fogging of the inner lens and improving visual clarity when wearing the device.

[0014] This invention provides a goggle with a detachable flexible element. It has the following advantages: These goggles with detachable flexible components effectively reduce UV damage to the eyes during outdoor sports or cycling thanks to the UV-protective coating on the outer lens. Simultaneously, the synergistic effect of the inner and outer lenses effectively blocks airflow from directly hitting the eyes, preventing discomfort. When the goggles become too hot or sweaty, pressing one end of the lever pulls the other end out of the goggle body, stretching the outer lens and connector outwards. This exposes the micropores on the inner lens surface, allowing air to pass through and effectively eliminating moisture inside the goggles. This prevents stuffiness and fogging of the inner lens caused by sweat, significantly improving wearing comfort. Furthermore, the outer lens's shielding design ensures that external airflow does not directly enter the goggles through the micropores on the inner lens and connector during cycling, thus preventing direct airflow into the eyes while maintaining ventilation. When ventilation is not required, pressing the outer lens will cause the second magnetic strips at both ends of the outer lens to attach to the first magnetic strip of the goggle body, enabling the outer lens to retract quickly and further improving ease of use.

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

[0018] Example 1: Please refer to Figure 1-8 This invention provides a technical solution: a goggle with detachable flexible components, comprising: a fixing strap 2, made of elastic and stretchable material, used to fix the goggles when worn; further comprising: a frame assembly 1, fixedly connected to both ends of the fixing strap 2, used to fix the internal components of the goggles; a lens assembly 3, installed inside the frame assembly 1, used to provide eye protection when worn; a ventilation assembly 4, located at the top of the frame assembly 1, used to control the opening and closing of the ventilation channel of the frame assembly 1; and two telescopic components 5, respectively installed inside both ends of the frame assembly 1 and connected to the ventilation assembly 4. This embodiment provides a detachable flexible element goggle. The lens assembly 3 is installed inside the frame assembly 1, which can seal the internal space when worn, effectively blocking external dust, sand, and other irritants to the eyes, while also providing good ventilation. The ventilation assembly 4 is located at the top of the frame assembly 1 and can control the opening and closing of the ventilation channel, adjusting the ventilation state inside the goggle as needed to solve the problems of internal humidity and fogging caused by prolonged wear. The telescopic assembly 5 is connected to the ventilation assembly 4, further optimizing the ventilation effect and ensuring a comfortable environment inside the goggle in different environments. This effectively solves problems such as discomfort and poor ventilation when wearing goggles, improving the practicality and wearing experience of the goggles.

[0019] Example 2: Please refer to Figure 1-8 This invention provides a technical solution: the frame assembly 1 includes a goggle body 101, with a slot 102 formed on the inner surface of the goggle body 101. The goggle body 101 is made of rubber, and one side of the goggle body 101 conforms to the contour of the user's face. A rotating shaft 104 is embedded at both ends of the goggle body 101, and the rotating shaft 104 passes through the middle of a lever 105. The lever 105 is rotatably connected to the rotating shaft 104, and one end of the lever 105 has an L-shaped structure. A ventilation groove 107 is provided on the top surface of the goggle body 101, and the ventilation grooves 107 are distributed in an arc-shaped, evenly spaced pattern. Grooves are provided on the inner sides of both ends of the goggle body 101, and a first magnetic strip 103 is embedded inside the groove. The first magnetic strip 103 corresponds to two second magnetic strips 106, and the second magnetic strips 106... The lens assembly 3 includes an outer lens 301, with grooves embedded on the inner sides of both ends of the outer lens 301. A second magnetic strip 106 is embedded in the grooves at both ends of the outer lens 301. A connector 302 is provided on the inner side of the outer lens 301, and an inner lens 303 is provided on the other end of the connector 302. The inner lens 303 is embedded in the slot 102. The bottom edge of the inner lens 303 is evenly provided with ventilation micropores. The inner lens 303 is made of transparent material. The surface of the outer lens 301 is provided with an anti-ultraviolet coating. The outer lens 301 and the connector 302 are bonded together, and the other end of the connector 302 is bonded to the inner lens 303 by adhesive bonding. The surface of the connector 302 has a multi-bent structure for the extension and retraction of the connector 302. The connector 302 is made of rubber and has ventilation micropores on its surface. In this embodiment, the goggles effectively reduce UV damage to the eyes during outdoor sports or cycling thanks to the coating on the surface of the outer lens 301. Simultaneously, the inner lens 303, in conjunction with the outer lens 301, effectively blocks airflow from directly hitting the eyes, preventing discomfort. Furthermore, when the internal temperature of the goggles is too high or there is sweating, to prevent discomfort from internal moisture and fogging of the inner lens 303, pressing one end of the lever 105 pulls one end of the outer lens 301 out of the goggle body 101, stretching the outer lens 301 and connector 302 outwards. This exposes the micropores on the surface of the inner lens 303, allowing air to pass through. The goggles allow for ventilation through the micropores on the surfaces of the inner lens 303 and the connector 302, effectively eliminating moisture inside the goggles and preventing stuffiness caused by sweating during wear, thus greatly improving wearing comfort. Simultaneously, due to the obstruction of the outer lens 301, external airflow does not directly enter the goggles through the micropores on the surfaces of the inner lens 303 and the connector 302 during cycling, thus providing ventilation while preventing airflow from blowing directly onto the eyes. When ventilation is not required, pressing the outer lens 301 allows the second magnetic strips 106 at both ends of the outer lens 301 to adhere to the first magnetic strip 103 of the goggle body 101, enabling the outer lens 301 to retract quickly and improving ease of use.

[0020] Example 3: Please refer to Figure 1-8 This invention provides a technical solution: a ventilation component 4 includes a bimetallic strip 401, which has an arc-shaped structure and is attached to the surface of the ventilation slot 107. The bimetallic strip 401 is composed of two layers of thin metal sheets, namely copper and iron. Rivets 403 are fixed to both ends of the bimetallic strip 401, and the middle part of the bimetallic strip 401 is connected to the top of the goggle body 101 via a connecting bolt 402. The ventilation component 4 also includes connecting pieces 501, of which two are provided. Each connecting piece 501 is connected to one end of the bimetallic strip 401, and a telescopic tube 503 is provided at one end of each connecting piece 501. One end of the telescopic tube 503 is inserted into the goggle body 101. The telescopic tube 503 has a hollow structure inside. The outer wall of the telescopic tube 503 has a strip-shaped groove, and the outer wall of the telescopic tube 503 slides in contact with the goggle body 101. One end of the connecting piece 501 has a groove, and the inside of the groove slides in contact with the outer wall of the telescopic tube 503. Two limiting rings 502 are fitted on the outside of the telescopic tube 503. The limiting rings 502 are located above and below the connecting piece 501, respectively. The groove on the surface of the telescopic tube 503 slides in connection with the limiting block 504. The limiting block 504 is embedded in the goggle body 101. The opening of the groove on the surface of the telescopic tube 503 faces the surface of the inner lens 303. In this embodiment, a ventilation slot 107 and a bimetallic strip 401 are provided at the top of the frame. When the outdoor temperature is high, the bimetallic strip 401 will deform due to heat, allowing its two ends to naturally bend and curl up. This allows the two ends of the bimetallic strip 401 to detach from the ventilation slot 107, thereby providing a certain degree of ventilation inside the goggles and reducing the stuffiness and discomfort inside. At the same time, when the two ends of the bimetallic strip 401 curl up, they can drive the telescopic tube 503 to move upward through the connecting piece 501. The upward movement of the telescopic tube 503... At the same time, it can expose the surface holes and grooves, so that the external airflow can enter the interior through the top end of the holes and grooves on the outer wall of the telescopic tube 503, and then be forced into the goggles through the telescopic tube, blowing towards the surface of the inner lens 303. This can suppress the fogging of the inner lens 303 and prevent the fogging on the surface of the inner lens 303 from interfering with vision due to internal stuffiness. When the temperature is low, the bimetallic strip 401 can restore its deformation and fit with the surface of the ventilation groove 107, so that the ventilation groove 107 can be closed, and the telescopic tube 503 can be automatically reset.

[0021] The present invention provides a goggle with a detachable flexible element, the overall working process of which is as follows: Wearing and securing: The wearer secures the goggles to their head using the elastic strap 2, ensuring a tight fit between the goggles and face for a stable wearing effect.

[0022] UV protection and airflow blocking: The UV-protective coating on the surface of the outer lens 301 effectively blocks UV rays from harming the eyes. At the same time, the synergistic effect of the inner lens 303 and the outer lens 301 effectively blocks external airflow from blowing directly into the eyes, reducing the irritation of the eyes caused by wind and sand.

[0023] Ventilation and air permeability control: When the internal temperature of the goggles is too high or when sweating occurs, the wearer can press one end of the lever 105 to pull one end of the outer lens 301 out of the frame body 101, and the outer lens 301 and the connector 302 will be pulled outward.

[0024] This action exposes the breathable micropores on the surface of the inner lens 303, allowing air from inside and outside the goggles to circulate through the micropores on the surfaces of the inner lens 303 and the connector 302. This effectively eliminates moisture inside the goggles, prevents the inner lens 303 from fogging up, and improves wearing comfort.

[0025] Meanwhile, the shielding design of the outer lens 301 ensures that external airflow will not directly enter the interior through the micropores on the surface of the inner lens 303 and the connector 302 during cycling, thus preventing airflow from blowing directly into the eyes.

[0026] Automatic ventilation control: When the ambient temperature is high, the bimetallic strip 401 in the ventilation component 4 deforms due to heat, and its two ends naturally bend and lift up, detaching from the ventilation slot 107, thus opening the ventilation slot 107.

[0027] When the two ends of the bimetallic strip 401 are raised, the telescopic tube 503 is moved upward through the connecting piece 501, and the holes and grooves on the surface of the telescopic tube 503 are exposed. The external airflow enters the goggles through the holes and grooves on the outer wall of the telescopic tube 503 and blows onto the surface of the inner lens 303, further suppressing the fogging of the inner lens 303.

[0028] When the ambient temperature drops, the bimetallic strip 401 recovers its deformation and adheres to the surface of the ventilation slot 107, closing the ventilation slot 107, while the telescopic tube 503 automatically resets. Through the above-described workflow, the goggles of this invention can effectively reduce the damage of ultraviolet rays to the eyes during outdoor sports or cycling, block airflow from blowing directly into the eyes, and significantly improve wearing comfort and ease of use through adaptive ventilation adjustment and convenient disassembly and installation design.

[0029] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics.
