Specific implementation method:

[0028] The present invention is further described below with reference to specific embodiments. Figure 1 —11:

[0029] The utility model provides a helmet lens opening and closing mechanism, comprising a helmet body 1 and a lens 2, wherein the helmet body 1 is provided with two groups of opening and closing components, and the two ends of the lens 2 are connected to the helmet body 1 through the opening and closing components so as to be openable and closable, the opening and closing components comprising a first shell 3 connected to the helmet body 1, a second shell 4 is provided on one side of the first shell 3, a cavity is formed between the first shell 3 and the second shell 4, a guide rod 5 and a rotating arm 6 are provided in the cavity, a slider 7 is slidably provided on the guide rod 5, one end of the rotating arm 6 is rotatably connected to the slider 7, and the other end extends out of the cavity and is connected to the lens 2, a return spring 8 is sleeved on the guide rod 5, one end of the return spring 8 is pressed tightly against the slider 5, and the other end is pressed tightly against the corresponding inner wall of the cavity, the guide rod 5, the slider 7, and the return spring 8 limit the lens 2 to make a linear motion, the rotating arm 6 realizes the rotation of the lens 2 to an open state, and the rotating arm 6 positions the lens 2 after opening through a locking structure.

[0030] The opening and closing assembly of the utility model can realize the switching between opening and closing of the real lens 2 without disassembling, and the switching is convenient.

[0031] The opening and closing switching of the utility model is as follows:

[0032] When it is necessary to open, pull the lens 2, the slider 7 compresses the return spring 8 and moves linearly along the outer side of the guide rod 5, and then rotate the lens 2 upward to above the forehead of the helmet body 1, and the rotating arm 6 rotates around the connection point with the slider 7. Under the action of the locking structure, the lens 2 is kept in this position. At this time, the lens 2 is in the open state.

[0033] When it is necessary to close, pull the lens 2 to release the locking structure, and the lens 2 rotates downward to drive the rotating arm 6 to rotate around the connection point with the slider 7. Under the action of the spring force of the reset spring 8, the slider 7 is driven to move linearly along the inner side of the guide rod 5 until the lens 2 is reset. At this time, the lens 2 is in the closed state.

[0034] Specifically, the locking structure includes locking grooves 9 respectively disposed on the opposite side walls of the first housing 3 and the second housing 4 and locking protrusions 10 disposed on the two side walls of the rotating arm 6. When locked, the locking protrusions 10 are located in the locking grooves 9.

[0035] Due to the effect of the return spring 8 , the clamping protrusion 10 always has a force against the clamping slot 9 to ensure that the clamping protrusion 10 is located in the clamping slot 9 without displacement.

[0036] In order to make the linear motion more stable, the side walls of the first housing 3 and the second housing 4 where the card slot 9 is provided are provided with moving tracks 11, and the two side arms of the rotating arm 6 are provided with protrusions 12, which move along the moving tracks 11, and the card slot 9 is located at the outer end of the moving tracks 11. Generally speaking, during linear motion, the outer side walls of the protrusions 12 and the card slot 10 both move along the moving tracks 11.

[0037] In order to prevent the guide rod 5 from circumferential displacement, the slider 7 is provided with a first protruding rod 13 and a second protruding rod 14, and the first shell 3 and the second shell 4 are provided with a strip hole 15 and a strip groove 16, and the first protruding rod 13 and the second protruding rod 14 are respectively arranged in the strip hole 15 and the strip groove 16. When the slider 7 moves along the guide rod 5, the first protruding rod 13 and the second protruding rod 14 move in the strip hole 15 and the strip groove 16 respectively.

[0038] It should be noted that the present embodiment adopts the strip-shaped holes 15 and the strip-shaped grooves 16 , and both adopting the strip-shaped holes or the strip-shaped grooves are equivalent implementation modes.

[0039] In addition, the strip-shaped holes 15 and the strip-shaped grooves 16 also have a guiding function.

[0040] Furthermore, a through hole 17 is provided at one end of the rotating arm 6 , and one end of the rotating arm 6 is sleeved on the first and second protruding rods 14 through the through hole 17 and is limited between the slider 7 and the side wall of the first housing 3 .

The diameter of the head portion 19 is larger than the diameter of the rod portion 18. Mounting grooves 20 adapted to the head portion 19 are respectively provided on the first shell 3 and the second shell 4. The head portion 19 is limited in the mounting groove 20. A rod mounting hole 21 is provided on one end of the first shell 3 and / or the second shell 4 relative to the mounting groove 20, and the other end of the rod portion 19 is inserted into the rod mounting hole 21.

[0042] It should be noted that the first housing 3 and the second housing 4 are fixedly connected by fasteners. That is, when the opening and closing assembly fails, the second housing 4 can be disassembled for maintenance.

[0043] The opening and closing assembly of the utility model is embedded in the helmet body 1. The first shell 3 and the helmet body 1 adopt an integrally formed structure.

[0044] The utility model is provided with a face cover 22 on the other side of the second shell 4, and the face cover 22 is arranged flush with the inner wall of the helmet body 1, so that the entire helmet is clean and tidy in appearance. Usually, the face cover 22 and the helmet body 1 are connected by a tight fit.

[0045] During maintenance, the surface cover 22 and the second shell 4 can be removed.
