[0002] In outdoor sports like skiing, helmets are crucial equipment for protecting the user's head. As an important component, helmet goggles not only block wind and snow from harming the eyes but also effectively block ultraviolet rays, ensuring that the user can maintain a clear field of vision in various environments. The goggles' control structure directly affects their ease of use and stability, which in turn relates to safety and user experience.

[0003] Existing goggles are connected to the helmet by a rotating hinge, allowing the goggles to open around the hinge. However, this method has certain drawbacks in vibration environments, as it cannot effectively maintain the position of the goggles, causing them to sway and affecting the user's vision.

[0007] Furthermore, the movable block includes a first movable part, a connecting block, and a second movable part connected in sequence. The inner walls of both the front shell and the rear shell are provided with sliding grooves, and the first movable part and the second movable part are slidably connected inside the sliding grooves.

[0008] Furthermore, a first mounting groove corresponding to the spring is provided on one side of the first movable part. The first mounting groove is a semi-closed structure and a first positioning post is fixedly connected to its inner wall.

[0009] Furthermore, the front shell includes a main shell and an auxiliary shell, both of which are fixedly connected to the rear shell.

[0013] (3) Beneficial effects Compared with the prior art, the beneficial effects of this utility model are as follows: This invention utilizes a windshield pull to extend a control rod horizontally from the housing. The control rod then causes a movable block to slide within the housing, compressing a spring. Once the control rod's connecting part extends out of the housing, rotating the windshield causes the control rod to rotate around a pivot and open to a near-vertical position. The spring's restoring force then resets the movable block, and the control part of the control rod locks onto the outside of the housing for a limiting position, thus securing the opened windshield. This effectively maintains the windshield's position even in vibrating environments, preventing it from shaking and resulting in better performance. Attached Figure Description

[0025] This specific embodiment is a windshield stretching and retraction control structure, such as... Figure 9-10 As shown, this structure is used to connect the helmet body 10 and the goggles 11, as follows: Figures 1-8As shown, the helmet includes a helmet body 10, a goggle 11, and a goggle extension / retraction control structure. The goggle extension / retraction control structure includes a housing 1, with a movable block 2 slidably connected inside the housing 1. A spring 3 is installed between the movable block 2 and the inner wall of the housing 1. One end of the movable block 2 is rotatably connected to a control rod 5 via a pin 4. The control rod 5 includes a rod body 501 and a control part 502 extending outside the pin 4. The other end of the control part 502 is arc-shaped to facilitate rotation. The end of the rod body 501 away from the control part 502 passes through the housing 1 and is fixedly connected to a connecting part 503. When the control rod 5 is pulled out from inside the housing 1, the spring 3 is activated by the movable block 2. The spring 3 returns to its restoring force after rotating the control lever 5, causing the control part 502 to be locked onto the outside of the outer shell 1. The helmet body 10 has a mounting part 12 on the side near the visor 11. The inner wall of the mounting part 12 has mounting grooves 13 on both sides. The outer shell 1 is fixedly connected to the inside of the mounting groove 13. The visor 11 is fixedly connected to the connecting part 503. The mounting part 12 can be stepped and extends to the front and rear sides of the helmet body 10. After the outer shell 1 is fixedly connected to the inside of the mounting groove 13 by adhesive, the connecting part 503 is flush with the mounting part 12. After the visor 11 is lowered and retracted, the visor 11 contacts the upper side of the mounting part 12, and the surface is a plane.

[0026] To facilitate the fixing of the goggles 11 to the connecting part 503, such as Figure 2 and Figure 5 As shown: In this embodiment, two insertion parts 1101 are fixedly connected to both ends of the goggle 11, and a locking block 1102 is fixedly connected to the other end of the insertion part 1101. A slot 5031 corresponding to the insertion part 1101 is opened on one side of the connecting part 503, and a slot 5032 corresponding to the locking block 1102 is opened on the inner wall of the slot 5031. By inserting the two insertion parts 1101 of the goggle 11 into the slot 5031, the insertion parts 1101 will deform to make the locking block 1102 lock into the slot 5032. The connecting part 503 is triangular, so that the inside of the slot 5031 is connected to the outside, which facilitates disassembly.

[0027] To facilitate the installation of the internal movable block 2, spring 3, and control lever 5, such as Figure 3 , Figure 6 and Figure 7 As shown: In this embodiment, the outer shell 1 includes a front shell 101 and a rear shell 102. A through hole 103 corresponding to the control rod 5 is provided between the front shell 101 and the rear shell 102. In this way, the front shell 101 and the rear shell 102 can be fixed by screws, which is convenient for disassembly and installation. The movable block 2 slides in the outer shell 1 to deform the spring 3.

[0028] To make the sliding of active block 2 more stable, such as Figure 4 , Figure 6 and Figure 7As shown: In this embodiment, the movable block 2 includes a first movable part 201, a connecting block 202, and a second movable part 203 connected in sequence. The inner walls of the front shell 101 and the rear shell 102 are each provided with at least two sliding grooves 204. The first movable part 201 and the second movable part 203 are slidably connected inside the sliding grooves 204. The sliding grooves 204 guide the movement of the first movable part 201 and the second movable part 203 to avoid deviation.

[0029] To position one end of spring 3 so that spring 3 can be stably compressed, such as... Figure 4 As shown: In this embodiment, a first mounting groove 205 corresponding to the spring 3 is provided on one side of the first movable part 201. The first mounting groove 205 is a semi-closed structure and a first positioning post 206 is fixedly connected to the inner wall. The spring 3 is installed in the first mounting groove 205 and sleeved on the first positioning post 206 to prevent displacement during compression.

[0030] In order to position the other end of spring 3 so that spring 3 can be stably compressed, such as Figure 3 , Figure 4 and Figure 7 As shown: In this embodiment, the front shell 101 includes a main shell 1011 and an auxiliary shell 1012. Both the main shell 1011 and the auxiliary shell 1012 are fixedly connected to the rear shell 102. A second mounting groove 1013 corresponding to the spring 3 is provided on one side of the auxiliary shell 1012. The second mounting groove 1013 is a semi-closed structure and a second positioning post 1014 is fixedly connected to its inner wall. The spring 3 is sleeved in the second positioning post 1014. The opening directions of the first mounting groove 205 and the second mounting groove 1013 are opposite to ensure that the spring 3 will not displace while being compressed.

[0031] To ensure a secure connection between the main housing 1011 and the rear housing 102, such as Figure 6 and Figure 7 As shown: In this embodiment, a plurality of protrusions 104 are fixedly connected to the side of the main housing 1011 near the rear housing 102, and the side of the rear housing 102 near the main housing 1011 is provided with grooves 105 corresponding to the protrusions 104; in this way, after the main housing 1011 and the rear housing 102 are fixed, the protrusions 104 and the grooves 105 cooperate to prevent displacement.

[0032] Working principle: By using the control structure of this utility model, the goggles 11 are mounted on the helmet body 10. When in use, pulling the goggles 11 causes the control rod 5 to extend horizontally from the outer shell 1. At this time, the control rod 5 causes the movable block 2 to slide within the outer shell 1 and compress the spring 3. After the connecting part 503 of the control rod 5 extends out of the outer shell 1, rotating the goggles 11 causes the control rod 5 to rotate around the pin 4 and open to an approximately vertical state. At this time, due to the presence of the control part 502, the size after rotation will be larger than the through hole 103 from which the control rod 5 extends. Figure 8 As shown, when the goggles 11 are released, the restoring force of the spring 3 causes the movable block 2 to return to its original position. The control part 502 of the control lever 5 is locked on the outside of the housing 1 to limit the movement, thereby fixing the opened goggles 11. Even in a vibrating environment, the position of the goggles 11 can be effectively maintained, making it less likely for the goggles 11 to shake, resulting in better performance.

[0033] All technical features in this embodiment can be freely combined according to actual needs.

[0034] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
