Abstract
Description
Technical Field
[0001] This utility model relates to the field of helmet lens film technology, specifically to a magnetically absorbing helmet lens film and a helmet. Background Technology
[0002] Helmet visor films can protect helmet visors and provide functions such as anti-fog, waterproofing, or optical variable ink. They are also cheaper than optical variable ink lenses and waterproof lenses, so they are widely used in the helmet visor field.
[0003] Currently, the main ways in which helmet visor films are combined with helmet visors on the market include the following:
[0004] (1) Full-coverage pasting: This method is prone to producing air bubbles during pasting and is not suitable for most people.
[0005] (2) Apply adhesive around the perimeter and attach adhesive strips around the perimeter. This method only sets adhesive strips around the perimeter of the film. However, applying adhesive around the perimeter to fix the film requires a large thickness of adhesive strips, which makes the film appear to be thicker. In addition, there is an air layer between the film and the lens, which not only affects the optical performance but also makes it prone to fogging.
[0006] (3) Mechanical connection structure (such as screws) The film is fixed to the lens by mechanical connection structure and electrostatic adsorption is used to make the film adhere to the lens. This method requires the helmet lock to set a specific fixing structure and can only be used for helmets with a specific structure. After this method is applied, water will flow from the gap to the space between the film and the helmet. Utility Model Content
[0007] To address the shortcomings of existing technologies, this utility model provides a magnetically attached helmet lens film and helmet, which simplifies the application process, eliminates air bubbles, and facilitates easy replacement. It also prevents water from flowing through gaps between the film body and the lens, and the film does not appear very thick after application.
[0008] This utility model provides a magnetically attached helmet lens film, comprising:
[0009] A thin film body is used to cover the surface of the lens, and a waterproof adhesive layer is provided on the upper edge of the thin film body near the lens.
[0010] Two pairs of magnetic clamping members are used to fix the left and right ends of the film body to the lens respectively. Each of the magnetic clamping members includes a first magnetic attracting member and a second magnetic attracting member that can be magnetically attracted to each other. The first magnetic attracting member is used to clamp the outside of the film body, and the second magnetic attracting member is used to clamp the outside of the lens.
[0011] Furthermore, both the first magnetic attractor and the second magnetic attractor are magnets, or one of the first magnetic attractor and the second magnetic attractor is a magnet, and the other is a metal that can attract the magnet.
[0012] Furthermore, the first magnetic attractor and the second magnetic attractor are in the shape of a circle, a regular polygon, a ring, or other irregular shapes.
[0013] Furthermore, the first magnetic attractor and the second magnetic attractor have the same shape.
[0014] Furthermore, the first magnetic accumulator is attached to the outside of the film body by a first adhesive layer, and a second adhesive layer is provided on one side of the second magnetic accumulator for attaching the second magnetic accumulator to the outside of the lens.
[0015] Furthermore, the adhesive force between the waterproof adhesive layer and the film body is greater than the adhesive force between the waterproof adhesive layer and the lens.
[0016] Furthermore, the second adhesive layer is one of self-adhesive, acrylic pressure-sensitive adhesive, PU pressure-sensitive adhesive or silicone pressure-sensitive adhesive, and a release layer is provided on the outside of the second adhesive layer.
[0017] Furthermore, the adhesive force between the waterproof adhesive layer and the film body is greater than the adhesive force between the waterproof adhesive layer and the lens.
[0018] Furthermore, the thickness of the waterproof adhesive layer is 20-100 μm;
[0019] The waterproof adhesive layer is made of one of acrylic pressure-sensitive adhesive, PU pressure-sensitive adhesive or silicone pressure-sensitive adhesive.
[0020] This utility model also provides a helmet, which includes any of the above-mentioned magnetically attached helmet lens film.
[0021] The beneficial effects of this utility model are reflected in:
[0022] The film body of this application is clamped and fixed to the lens by two pairs of magnetic clamps. The film application method is simple, bubble-free, and easy to replace. At the same time, a waterproof adhesive layer is set on the upper edge of the film body. The upper edge of the film body is attached to the lens by the waterproof adhesive layer. This can prevent water from flowing into the gap between the film body and the lens. The film body is mainly fixed by magnetic clamps. The waterproof adhesive layer is only used to seal the gap between the upper edge of the film body and the lens. Therefore, the thickness can be low and the film will not look very thick after application. Attached Figure Description

Detailed Implementation
[0027] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the present invention and should not be construed as limiting the scope of protection of the present invention.
[0028] It should be noted that, unless otherwise stated, the technical or scientific terms used in this application shall have the ordinary meaning as understood by one of ordinary skill in the art to which this utility model pertains.
[0029] like Figure 1 and Figure 2 As shown, this embodiment of the present invention provides a magnetically attached helmet lens film, including a film body 100 and two pairs of magnetic clamping members 200.
[0030] The film body 100 is used to cover the surface of the lens 300. A waterproof adhesive layer 110 is provided on the upper edge of the film body 100 near the lens 300. When applying the film, the upper edge of the film body 100 is attached to the lens 300 through the waterproof adhesive layer 110. A release layer is provided outside the waterproof adhesive layer 110. When applying the film, the release layer needs to be peeled off.
[0031] Optionally, the film body 100 can be at least one of conventional anti-fog film, waterproof film, or photochromic film.
[0032] Optionally, the adhesive force between the waterproof adhesive layer 110 and the film body 100 is greater than the adhesive force between the waterproof adhesive layer 110 and the lens 300. This ensures that when the film body 100 is removed, the waterproof adhesive layer 110 can still adhere to the film body 100 and be removed together.
[0033] Optionally, the waterproof adhesive layer 110 is made of one of acrylic pressure-sensitive adhesive, PU pressure-sensitive adhesive or silicone pressure-sensitive adhesive, so that no adhesive residue will remain when the film body 100 is removed.
[0034] Preferably, the thickness of the waterproof adhesive layer 110 is 20-100 μm. The waterproof adhesive layer 110 is mainly used for sealing to prevent water from flowing into the gap between the film body 100 and the lens 300, so it does not need to be too thick.
[0035] Two pairs of magnetic clamping members 200 are used to fix the left and right ends of the film body 100 to the lens 300 respectively. Each magnetic clamping member 200 includes a first magnetic attracting member 210 and a second magnetic attracting member 220 that can be magnetically attracted to each other. The first magnetic attracting member 210 is used to clamp the outside of the film body 100, and the second magnetic attracting member 220 is used to clamp the outside of the lens 300.
[0036] It is understood that, in order to ensure that the first magnetic attractor 210 and the second magnetic attractor 220 can magnetically attract each other, both the first magnetic attractor 210 and the second magnetic attractor 220 are magnets, or one of the first magnetic attractor 210 and the second magnetic attractor 220 is a magnet and the other is a metal that can attract the magnet. Preferably, in this embodiment, both the first magnetic attractor 210 and the second magnetic attractor 220 are magnets, so that the attraction force is greater.
[0037] The first magnetic attractor 210 and the second magnetic attractor 220 can be circular, regular polygonal, annular, or other irregular shapes, and can be configured as magnets with specific shapes as required.
[0038] Preferably, the first magnetic attractor 210 and the second magnetic attractor 220 have the same shape.
[0039] In some embodiments, the first magnetic absorbing member 210 is attached to the outside of the film body 100 by the first adhesive layer 211, which can prevent the first magnetic absorbing member 210 from shifting to the film body 100 after the film is applied. The second magnetic absorbing member 220 is provided with a second adhesive layer 221 on one side for attaching the second magnetic absorbing member 220 to the outside of the lens 300, which can prevent the second magnetic absorbing member 220 from shifting to the lens 300 after the film is applied.
[0040] Optionally, the second adhesive layer 221 is one of self-adhesive, acrylic pressure-sensitive adhesive, PU pressure-sensitive adhesive or silicone pressure-sensitive adhesive, and a release layer is provided on the outside of the second adhesive layer 221. When fixing the second magnetic accumulator 220, the release layer on the second magnetic accumulator 220 is peeled off, and then the second magnetic accumulator 220 is aligned with the first magnetic accumulator 210 and pasted and fixed on the lens 300.
[0041] The helmet lens 300 of this application is applied as follows: the first magnetic clasp 210 is attached to the outside of the film body 100 through the first adhesive layer 211. When applying the film, the film body 100 is gently placed on the lens 300, and the film body 100 is initially attached to the lens 300 by electrostatic action; the release layer outside the second adhesive layer 221 on the second magnetic clasp 220 is peeled off, and the second magnetic clasp 220 is attached to the side of the lens 300 away from the film body 100, and the position and angle of the second magnetic clasp 220 are the same as those of the first magnetic clasp 210; the film body 100 is removed, the release layer on the waterproof adhesive layer 110 is peeled off, and it is reattached to the lens 300.
[0042] The waterproof adhesive layer 110 uses traceless nano-adhesive, which can be easily peeled off. Therefore, the film replacement in this application is very convenient, and when re-attaching, there is no need to reposition it. Simply align the first magnetic member 210 with the second magnetic member 220.
[0043] The film body 100 of this application is clamped and fixed to the lens 300 by two pairs of magnetic clamping members 200. The film application method is simple, bubble-free, and easy to replace. At the same time, a waterproof adhesive layer 110 is provided on the upper edge of the film body 100. The upper edge of the film body 100 is adhered to the lens 300 by the waterproof adhesive layer 110. This can prevent water from flowing from the gap to the space between the film body 100 and the lens 300. The film body 100 is mainly fixed by the magnetic clamping members 200. The waterproof adhesive layer 110 is only used to seal the gap between the upper edge of the film body 100 and the lens 300. Therefore, the thickness can be low and the film will not look very thick after application.
[0044] This utility model embodiment also provides a helmet, which includes any of the above-described magnetically attached helmet lens film.
[0045] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model, and they should all be covered within the scope of the claims and specification of this utility model.
