Detailed Implementation

[0022] To make the objectives, technical solutions, and advantages of the embodiments of the present application more clear, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Generally, the components of the embodiments of the present application described and shown in the drawings herein can be arranged and designed in various different configurations.

[0023] like Figures 1 to 5 As shown, a helmet lens magnetic attraction structure of this embodiment includes an arc-shaped lens 1 and several magnetic attraction components 2.

[0024] Each magnetic attachment 2 is distributed at intervals on the inner edge of the curved lens 1 so that the curved lens 1 can be attached and fixed to the helmet (not shown) by each magnetic attachment 2, and can be easily disassembled and installed.

[0025] The magnetic fastener 2 includes a male buckle 21, a female buckle 22, and a magnet 23. The male buckle 21 and the female buckle 22 are located on the inner and outer sides of the curved lens 1, respectively, and are tightly fitted to each other on the curved lens 1. The connecting post 211 of the male buckle 21 passes through the through hole 11 provided on the inner side of the edge of the curved lens 1 and is tightly inserted into the connecting hole 221 of the female buckle 22. The outer end face of the male buckle 21 away from the connecting post 211 is provided with a receiving groove 212, and the magnet 23 is fixedly installed in the receiving groove 212.

[0026] Therefore, by setting the male buckle 21 and the female buckle 22, the magnet 23 can be fixed on the male buckle 21 in advance, and then the male buckle 21 and the female buckle 22 can be quickly fastened to be combined with both sides of the through hole 11 of the curved lens 1, which can improve the installation efficiency and convenience. In addition, the magnetic component 2 is a structure with the male buckle 21 and the female buckle 22 in cooperation, which can be replaced later, making maintenance convenient and avoiding damage to individual magnetic components 2 that would affect the normal wearing of the curved lens 1.

[0027] In this embodiment, the curved lens 1 includes a horizontal upper edge 12 and a curved lower edge 13, and a nose bridge groove 131 is recessed upward in the middle of the lower edge 13. The magnetic components 2 can be three, and are respectively disposed in the middle, left end, and right end of the inner side of the upper edge 12 of the curved lens 1. The magnets 23 on the inner end faces of each magnetic component 2 can be magnetically fixed to the helmet, achieving a stable connection.

[0028] Of course, there can be two or more magnetic components 2, and it is not limited to this embodiment.

[0029] To improve the structural stability of the male buckle 21 and the female buckle 22, in this embodiment, the female buckle 22 has a protruding locking boss 222 on the side near the male buckle 21. The outer periphery of the locking boss 222 forms a stepped surface 223, and the connecting hole 221 is recessed in the middle of the locking boss 222. The locking boss 222 is fitted into the through hole 11 of the curved lens 1, so that the female buckle 22 can be pre-locked into the through hole 11, and the stepped surface 223 of the female buckle 22 can abut against the outer surface 14 of the curved lens 1. The inner end face of the male buckle 21 has a protruding connecting post 211, which is inserted into the connecting hole 221, and the inner end face of the male buckle 21 abuts against the locking boss 222 and the inner surface 15 of the curved lens 1. In this way, both the male buckle 21 and the female buckle 22 can fit tightly against the inner and outer sides of the curved lens 1.

[0030] In this embodiment, the connecting hole 221 is a polygonal hole, which can be a pentagonal hole, a hexagonal hole, etc.; the connecting post 211 is a cylinder, which is tightly inserted into the polygonal hole. This achieves a tight fit.

[0031] In this embodiment, the male buckle 21 and the female buckle 22 are frustum-shaped. The connecting post 211 and the connecting hole 221 are respectively disposed at the bottom of the frustum of the male buckle 21 and the female buckle 22, and the receiving groove 212 is disposed at the top of the frustum of the male buckle 21. The frustum-shaped structure has good stability, high structural strength, and is convenient for installation and operation.
