[0002] The lens of a protective mirror, such as a wind mirror, a snow mirror, etc., protects the eyes of a wearer from the influence of the external environment.

[0003] Since the protective mirror not only protects the eyes but also allows the wearer to observe the external environment through the lens of the protective mirror, the lens of the protective mirror needs to be cleaned before it can be used again when it is covered with dust, or the lens of the protective mirror needs to be replaced when it is scratched.

[0004] In order to improve the convenience of using the lens of the protective mirror and prolong the service life of the lens, it is thought that a rotating shaft with a transparent protective film wound thereon is arranged on the left and right sides of the protective mirror, the protective films on the left and right sides of the protective mirror are connected to each other, and the protective mirror can be used by rotating the rotating shaft to drive the protective film to move relative to the lens so as to protect the lens by the protective film. When the protective film laid on the outer surface of the lens is covered with dust or scratched, the protective mirror can be used without replacing the lens by laying a clean protective film on the lens by rotating the rotating shaft. Such a device with a rotating shaft with a transparent protective film wound thereon is generally a film winding unit.

[0005] However, the current film winding unit is generally installed on the lens or the frame of the protective mirror by screws, and tools such as a screwdriver are needed to assemble or disassemble the film winding unit and the lens or the frame, which is complicated. INVENTION CONTENTS

[0037] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme of the embodiments of the utility model will be described clearly and completely in combination with the drawings in the embodiments of the utility model below. Obviously, the described embodiments are part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0038] Figures 1 to 9 The quick mounting structure according to an embodiment of the utility model is schematically shown.

[0039] As shown in Figure 7 and Figure 9 , the quick mounting structure comprises a mounting column 20 and a bottom shell 311. The mounting column 20 is used to be arranged on a lens 50 or a frame. As shown in Figure 3 , Figure 4 , Figure 8 and Figure 9 , the mounting column 20 is integrally formed or processed with a first clamping groove 211. The bottom shell 311 is integrally formed or processed with a first passage 3111 through which an end of the mounting column 20 away from the lens 50 or the frame can pass. As shown in Figure 1 , Figure 7 and Figure 9 , the first passage 3111 comprises a first through hole 3111a, a first through slot 3111b and a second through hole 3111c communicated in sequence, the second through hole 3111c is arranged to allow the end of the mounting column 20 away from the lens 50 or the frame to pass through, the first through slot 3111b is smaller in width than the first clamping groove 211, the first through hole 3111a is only for the first clamping groove 211 of the mounting column 20 to pass through, and the bottom shell 311 can be elastically deformed.

[0040] When the quick mounting structure is used, the mounting column 20 can be arranged on the lens 50 or the frame. Then, the bottom shell 311 can be mounted on the mounting column 20 by placing the first clamping groove 211 in the first through hole 3111a to avoid the mounting column 20 from moving out of the first through hole 3111a without external force, as shown in Figures 1 to 6 ; or the bottom shell 311 can be separated from the mounting column 20 by applying external force to the mounting column 20 to extrude the side wall of the first clamping groove 211 of the bottom shell 311 by the first clamping groove 211, so that the bottom shell 311 is deformed and the first clamping groove 211 can pass through the first clamping groove 211 to enter the second through hole 3111c and pass through the second through hole 3111c to separate from the bottom shell 311, as shown in Figures 7 to 9 .

[0041] In some preferred embodiments, as shown in Figures 1 to 6As shown, the quick installation structure further comprises a moving piece 312, and the moving piece 312 and the bottom shell 311 constitute a first shell 31 of an embodiment of the application. The moving piece 312 is integrally formed or processed with a second channel 3121 for the end of the installation column 20 away from the lens 50 or the frame to pass through. The moving piece 312 is arranged to reciprocate relative to the bottom shell 311 between a first position and a second position, so as to be capable of clamping the first clamping groove 211 on the bottom shell 311 when the moving piece 312 is in the first position (as shown in Figures 1 to 6 ), that is, the first shell 31 clamps the first clamping groove 211; and the bottom shell 311 is capable of releasing the first clamping groove 211 when the moving piece 312 is in the second position (as shown in Figure 7 ). Thus, the first clamping groove 211 can be clamped on the bottom shell 311 or the bottom shell 311 is capable of releasing the first clamping groove 211 by reciprocating the moving piece 312 relative to the bottom shell 311 between the first position and the second position.

[0042] As one of the embodiments that the moving piece 312 reciprocates relative to the bottom shell 311 between the first position and the second position, the moving piece 312 reciprocates relative to the bottom shell 311 along a first direction through a first moving mechanism and a second moving mechanism arranged on different sides of the moving piece 312, so as to avoid the moving piece 312 from easily sliding off the bottom shell 311 through the first moving mechanism and the second moving mechanism arranged on different sides of the moving piece 312. As one of the embodiments of the first moving mechanism, as shown in Figure 7 , the first moving mechanism comprises a first slider 3124 and a first sliding groove 3112 matched with each other. The first slider 3124 is integrally formed, processed or connected on a first side of the moving piece 312. The first sliding groove 3112 is integrally formed or processed on the bottom shell 311. As one of the embodiments of the second moving mechanism, as shown in Figure 3 , Figure 4 , Figure 6 and Figure 8 , the second moving mechanism comprises a second slider 3125 and a second sliding groove 3113 matched with each other. The second slider 3125 is integrally formed, processed or connected on a second side of the moving piece 312. The second sliding groove 3113 is integrally formed or processed on the bottom shell 311. In some embodiments, the first slider 3124 is inserted into the first sliding groove 3112 along a second direction Y, and the second slider 3125 is inserted into the second sliding groove 3113 along a direction opposite to the first direction X. The second direction Y is not parallel to the first direction X, for example, perpendicular to each other.

[0043] In some preferred embodiments, as shown in Figure 6 , Figure 8 and Figure 9As shown, a first stop 3122 is integrally formed, machined or connected to the movable part 312. The first stop 3122 is configured to limit the movement of the movable part 312 relative to the bottom shell 311 in the opposite direction of the first direction X to the extreme position.

[0044] In some preferred embodiments, such as Figure 1 , Figure 3 , Figures 5 to 9 As shown, the quick-installation structure also includes a second housing 32. The first housing 31 and the second housing 32 constitute the housing body 30 of one embodiment of this application. The first housing 31 has a first state of clamping the mounting post 20 and a second state of releasing the mounting post 20. The second housing 32 is movable relative to the first housing 31 so that the first housing 31 can switch between the first state and the second state. The first housing 31 and the mounting post 20 are configured such that when the first housing 31 is in the first state, the mounting post 20 will not move relative to the lens 50 or the frame. Therefore, when the first housing 31 is in the first state, the purpose of mounting the first housing 31 on the lens 50 or the frame can be achieved; and when the first housing 31 is in the second state, the purpose of detaching the first housing 31 from the lens 50 or the frame can be achieved. In some embodiments, the first housing 31 and the second housing 32 are detachably connected to lock the first housing 31 in the first state; and when the second housing 32 is separated from the first housing 31, the second housing 32 can move relative to the first housing 31 first. In some embodiments, the first housing 31 and the second housing 32 are detachably connected by engaging. In some embodiments, the first housing 31 is engaged with the second housing 32 via a second slot 3114 integrally formed or machined on the bottom housing 311, and a buckle 321 integrally formed, machined, or connected on the second housing 32. In some embodiments, when the moving member 312 is in the first position, the first housing 32 is in the first state (e.g., Figures 1 to 6 (as shown); when the moving part 312 is in the second position, the first housing 32 can be in the second state (as shown). Figures 7 to 9 (As shown).

[0045] In some embodiments, the housing body 30 has a first working state that clamps the mounting post 20 (e.g., Figures 1 to 4 As shown), the mounting post 20 and the housing body 30 are configured such that when the housing body 30 is in a first working state, the mounting post 20 will not move relative to the lens 50 or the frame. For example, the first housing 31 is connected to the second housing 32, and the first housing 31 of the housing body 30 is in the first state, clamping the mounting post 20 to achieve the installation of the housing body 30 on the mounting post 20 of the lens 50 or the frame. The housing body 30 also has a second working state capable of releasing the mounting post 20 (e.g., ...). Figures 5 to 9(As shown) For example, the first housing 31 is separated from the second housing 32, and the moving member 312 moves relative to the bottom housing 311 in the first direction X, so that the first housing 31 is in the second state of releasing the mounting post 20 (as shown). Figures 7 to 9 As shown in the figure, at this time, the housing body 30 is in the second working state and the mounting post 20 is released to remove the housing body 30 from the lens 50 or the frame.

[0046] In some preferred embodiments, when the second housing 32 is engaged with the first housing 31, the movement of the movable member 312 relative to the bottom housing 311 can be restricted. This allows for quick disassembly and assembly of the second housing 32 and the first housing 31 without the use of tools. In some embodiments, Figure 1 , Figures 5 to 9 As shown, a second stop 3123 is integrally formed, machined, or connected to the movable member 312. When the second housing 32 is connected to the first housing 31, the second stop 3123 can limit the extreme position of the movable member 312 relative to the bottom housing 311 along the first direction X. For example, the second housing 32 can abut against one side of the second stop 3123. When the second stop 3123 moves relative to the second housing 32 along the first direction X, it will abut against the second housing 32. In this way, the second stop 3123 restricts the movement of the movable member 312 relative to the bottom housing 311 along the first direction X by limiting the movement of the second stop 3123 relative to the second housing 32. Thus, when the second housing 32 is connected to the first housing 31, the movement of the movable member 312 relative to the bottom housing 311 can be restricted by the second housing 32. In some embodiments, the first stop 3122 restricts the movement of the movable member 312 relative to the bottom shell 311 in the opposite direction of the first direction X to the extreme position where, when the second shell 32 can restrict the movement of the second stop 3123 relative to the second shell 32 in the first direction X, the first stop 3122 abuts against the bottom shell 311, and the bottom shell 311 restricts the movement of the first stop 3122 relative to the bottom shell 311 in the opposite direction of the first direction X. At this time (when the first shell 31 and the second shell 32 are connected), the movable member 312 will not move relative to the bottom shell 311, and the first shell 31 formed by the bottom shell 311 and the movable member 312 will not move relative to the second shell 32.

[0047] In some preferred embodiments, such as Figure 3 As shown, after the first housing 31 and the second housing 32 are connected, a first receiving cavity 300 is formed between them to accommodate the rotating shaft 40, and the rotating shaft 40 can rotate relative to the first housing 31. Thus, after the first housing 31 and the second housing 32 are connected, the rotating shaft 40, which can rotate relative to the first housing 31, can be accommodated in the first receiving cavity 300 between them, so that the protective film can be wrapped around the rotating shaft 40.

[0048] Figure 10The film winding unit according to an embodiment of the present application is shown schematically. The film winding unit comprises a rotating shaft 40 for winding a protective film, and the aforementioned quick mounting structure; wherein the rotating shaft 40 is arranged to be rotatable relative to the quick mounting structure. For example, the rotating shaft 40 is pivotally arranged on the second housing 32; or, the rotating shaft 40 is pivotally arranged on the bottom shell 311; or, when the second housing 32 is connected with the first housing 31, the rotating shaft 40 is pivotally arranged between the second housing 32 and the first housing 31. Thus, the film winding unit can be quickly mounted or dismounted with the lens 50 or the frame through the quick mounting structure.

The protective mirror comprises at least one of the lens 50 and the frame, and the aforementioned quick mounting structure, the mounting column 20 of the quick mounting structure is arranged on the lens 50 or the frame, the quick mounting structure is arranged in two groups and connected on two sides of the lens 50 or the frame respectively; or comprises at least one of the lens 50 and the frame, and the aforementioned film winding unit, the mounting column 20 of the quick mounting structure of the film winding unit is arranged on the lens 50 or the frame, and the film winding unit is arranged on one side of the lens 50 or the frame. Thus, the film winding unit can be quickly mounted or dismounted with the lens 50 or the frame through the quick mounting structure.

[0050] The mounting manner of the mounting column 20 arranged on the lens 50 or the frame can be realized as: the mounting column 20 is directly arranged on the lens 50 or the frame, as shown in Figure 3 、 Figure 4 and Figure 12 , the mounting column 20 comprises a column body 21 and a first blocking part 22, the column body 21 and the first blocking part 22 are connected through threads; the lens 50 is integrally formed or processed with a mounting hole 51; the column body 21 is integrally formed, processed or connected with a second blocking part 212 and a first clamping groove 211 arranged at the end of the second blocking part 212 away from the lens 50, the diameter of the second blocking part 212 is larger than that of the mounting hole 51; the first blocking part 22 has a large-diameter end with a diameter larger than that of the mounting hole 51 and a small-diameter end with a diameter smaller than that of the mounting hole 51, the small-diameter end is threadedly connected with the column body 21 after penetrating through the mounting hole 51. The mounting manner of the mounting column 20 arranged on the lens 50 or the frame can also be realized as: the mounting column 20 is fixed relative to the lens 50 or the frame when the bottom shell 311 is arranged on the mounting column 20.
