Description

Technical Field

[0001] This invention provides a ski goggle with easily detachable and detachable lenses, belonging to the field of ski goggle technology. Background Technology

[0002] As a crucial piece of protective gear for skiing, ski goggles typically consist of two main parts: the frame and the lenses. The frame is used to fit snugly against the wearer's face and supports the lenses; the lenses primarily serve to protect against wind, UV rays, strong sunlight, and impacts from snow or debris. To cope with different lighting conditions (such as sunny, cloudy, and nighttime), skiers need to quickly change lenses with different functions outdoors. Currently, most ski goggles on the market use a snap-on or embedded structure to secure the lenses. This involves the elastic clips on the edge of the lenses engaging with pre-set slots on the frame, allowing for quick installation and locking of the lenses.

[0003] However, the existing common disassembly and assembly structure has significant drawbacks. First, in actual skiing scenarios, users typically wear heavy gloves, greatly reducing finger dexterity. In low temperatures and strong winds, performing delicate lens disassembly and assembly is extremely difficult, often requiring users to remove their gloves. This not only causes cold and uncomfortable hands but also increases the risk of losing the gloves. Removing the lenses without removing the gloves is not only cumbersome, but snow or dirt adhering to the glove surface can easily contaminate the optical surface of the lenses, polluting them. Furthermore, when changing ski goggle lenses, a rapid replacement process can cause a sudden surge of air pressure inside the goggles, potentially causing barotrauma to the user's eyes (similar to the ear pressure caused by slamming a car door). Therefore, there is an urgent need for a method that allows for convenient, quick, and clean lens disassembly and assembly while wearing gloves, avoiding barotrauma to the user's eyes caused by rapid replacement. Utility Model Content

[0004] The technical problem this invention aims to solve is that when replacing ski goggles lenses, it is inconvenient to quickly and cleanly disassemble and install the lenses without removing gloves, and that replacing the lenses too quickly during use of ski goggles can cause air pressure damage to the user's eyes.

[0005] To solve the above problems, the present invention proposes the following technical solution: a ski goggle with easy-to-disassemble and assemble lenses, comprising a frame and lenses; the lenses are mounted on the frame, and the frame is connected to straps for easy wearing by the user;

[0006] The frame has a mounting groove, and the lens is located in the mounting groove; the inner side of the lens has a toothed groove, and the lens is connected to the frame via a magnetic assembly; a pull cord is fixedly connected to the lens for easy operation by the user.

[0007] As an improvement, the grooves are provided in a plurality of manners, and the plurality of grooves are evenly distributed on one side of the lens.

[0008] As an improvement, the tooth groove is connected to the outside.

[0009] As an improvement, the magnetic attraction component includes a fixed magnet and an attraction magnet; a plurality of fixed magnets are fixedly disposed in the mounting groove of the frame, and a plurality of attraction magnets that can be attracted to the fixed magnets are disposed on the inner side of the lens.

[0010] As an improvement, the frame is provided with a placement groove, and the pull cord is attached to the position of the placement groove.

[0011] The beneficial effects of this utility model are:

[0012] 1. These ski goggles utilize a magnetic attachment system and a pull cord for quick lens installation and removal. Simply pull the cord to apply force; no fine motor skills are required, making it easy to perform even while wearing heavy gloves, greatly improving the convenience of changing lenses outdoors. Simultaneously, it prevents gloves from directly contacting the lens's optical surface, thus preventing contamination of the lenses during installation and removal.

[0013] 2. By creating grooves on the inside of the lens to connect with the outside, airflow channels can be formed between the inside and outside of the ski goggles. When the lens is quickly removed or installed, the internal and external air pressure can be balanced in time. This ensures that the air pressure will not cause damage to the eyes when the lens is quickly replaced, thus improving the safety of lens replacement. Attached Figure Description

[0021] The present invention will be further described below with reference to the accompanying drawings.

[0022] Reference Appendix Figure 1 , 2 A ski goggle with easy-to-install and remove lenses: including a frame and lenses; lenses 3 are installed on the frame 1, and the frame 1 is connected to a strap 2 for easy wearing by the user; the overall structure of the ski goggle is ergonomically designed, the back of the frame 1 is made of flexible material to ensure a close fit to the face, and the length of the strap 2 is adjustable to accommodate different head circumferences.

[0023] Reference Appendix Figure 3 The frame 1 has a mounting groove 4, and the lens 3 is located in the mounting groove 4. The lens 3 is connected to the frame 1 via a magnetic assembly. The magnetic assembly includes a fixing magnet 7 and an adsorption magnet 8. Several fixing magnets 7 are fixedly installed in the mounting groove 4 of the frame 1, and several adsorption magnets 8, which can be attracted to the fixing magnets 7, are correspondingly installed on the inner side of the lens 3. The magnetic connection method replaces the traditional mechanical connection or buckle, making the installation of the lens 3 a simple alignment and adsorption process, greatly reducing the difficulty of operation. The even distribution of several fixing magnets 7 and adsorption magnets 8 ensures that the lens 3 is subjected to uniform force in the circumference, avoiding lens 3 deformation or poor sealing caused by stress concentration at a single point, and improving the reliability of the connection.

[0024] The lens 3 includes an outer frame and an optical element, with the optical element fixedly installed inside the outer frame. A pull cord 6 is fixedly connected to the lens 3 for easy operation by the user. A placement slot 5 is provided on the frame 1, and the pull cord 6 fits into the placement slot 5. During disassembly, simply pull the pull cord 6 along the side edge of the lens 3 to overcome the magnetic force with minimal force, allowing the lens 3 to be easily removed without touching the optical element of the lens 3.

[0025] Reference Appendix Figure 5 The lens 3 has grooves 9 on its inner side, which communicate with the outside. Several grooves 9 are evenly distributed on one side of the lens 3. This allows for very quick installation and removal of the lens 3 using magnetic attraction. For example, during installation, if the lens 3 were simply snapped down, it would create a sudden surge of air pressure inside the lens 3. The grooves 9 ensure that the air pressure inside and outside the lens 3 can be quickly and evenly adjusted, preventing a sudden surge of pressure when opening or closing the lens 3. This makes lens replacement smoother and avoids causing pressure damage to the eyes. The depth and width of the grooves 9 are precisely calculated to effectively conduct air pressure while being small enough to prevent the direct intrusion of large external particles or large amounts of moisture.

[0026] In the actual use of this utility model, when the user needs to replace lens 3, firstly, on the attached... Figure 1 , 2In this state, the user only needs to pinch the pull cord 6 with their thumb and forefinger (even while wearing heavy gloves) and apply an outward pull. This pull acts directly on the lens 3, overcoming the magnetic force between the fixing magnet 7 and the attracting magnet 8 in the magnetic assembly, allowing the lens 3 to quickly separate from the frame 1. Since the entire disassembly process is completed entirely through the pull cord 6, the user's hands or gloves do not need to contact the optical surface of the lens 3, thus fundamentally avoiding contamination of the inner side of the lens 3 by snow, water, and dirt, ensuring a clean field of vision. (See attached image.) Figure 3 When installing a new lens 3, simply align the new lens 3 with the mounting slot 4 on the frame 1. Utilizing the automatic adsorption properties of the magnetic component, the lens 3 can be precisely and firmly adsorbed into the predetermined position, achieving quick installation (during installation, the user holds the outer frame of the lens 3 without touching the optical lens).

[0027] Reference Appendix Figure 4 , 5 When the magnetic assembly is used to quickly remove or install lens 3, several grooves 9 on the inside of lens 3, which are connected to the outside, form a tiny air pressure balance channel. This channel dynamically and instantly balances the pressure on both sides of lens 3. This avoids air pressure damage to the user's eyes during quick lens 3 removal and installation, greatly improving the safety and reliability of lens 3 replacement.

[0028] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
