A spring-ratchet type helmet ventilation window structure with good operation feel will bring a good user experience to the rider.

[0003] The existing spring-ratchet type helmet ventilation window of the ratchet type generally includes a ventilation window body and a cover plate, the ventilation window body is provided with a ratchet, the cover plate is matched with the ratchet and can move in the length direction of the ratchet to realize ventilation opening and closing and gear shifting actuation. However, when the ratchet needs to be provided with multiple gears, since the connecting point of the ratchet and the ventilation window body is located at the end of the length direction of the ratchet, the switching resistance of the cover plate at each gear is different, which makes it difficult to keep the middle gears consistent with the end gears in terms of feel, the stability of the gear switching feel is poor, and the user experience is affected.

[0004] It should be noted that the information disclosed in the above background section is only used to strengthen the understanding of the background of the present disclosure, and therefore can include information that does not constitute prior art known to those of ordinary skill in the art.

[0010] The ventilation window body is provided with a ventilation hole and a through hole, and two groups of support arch bridges and ratchets are symmetrically arranged on opposite sides of the through hole. In the same group of support arch bridges and ratchets, the support arch bridge has elastic deformation ability, and the bottom is connected with the inner side of the through hole. The middle part of the ratchet is connected with the top of the support arch bridge, and the two ends of the ratchet are suspended in the through hole.

[0011] The push piece is movably connected with the ventilation window body and is configured to move along the preset direction to shield or open the ventilation hole, thereby realizing switching of the ventilation gear. The push piece is provided with a gear column foot which is inserted into the gear slot.

[0012] When the ventilation gear is switched, the gear column foot extrudes the two ratchet teeth, so that the support arch bridge is elastically deformed, and the two ratchet teeth are away from each other, and the gear column foot enters another adjacent gear slot from the gear slot.

[0013] In some embodiments, the ratchet teeth include a plurality of convex portions and concave portions which are alternately arranged along the preset direction, and the gear slot is formed between the concave portions of the two ratchet teeth.

[0014] In some embodiments, the gear slot is provided with three, the concave portion in the middle of the ratchet teeth is connected with the top of the support arch bridge, and the concave portion and the convex portion at both ends of the ratchet teeth are suspended in the through hole.

[0015] In some embodiments, the ventilation window body is provided with a sliding groove which is parallel to the preset direction; the push piece is provided with a sliding block which is matched with the sliding groove, and the push piece is movably matched with the sliding groove through the sliding block.

[0020] (III) Beneficial effects

[0021] Compared with the prior art, the technical scheme provided by the embodiments of the application has at least the following beneficial effects:

[0022] The elastic ratchet-type helmet ventilation window and helmet of the present application connect the ratchets to the inside of the through-hole via a supporting arch bridge, allowing the push piece to move in a preset direction. When the gear column foot squeezes the two ratchets, the supporting arch bridge can elastically deform, causing the two ratchets to move away from each other, so that the gear column foot moves from one gear slot to another adjacent gear slot, achieving the switching of ventilation gears. At the same time, because the two ends of the ratchet are suspended in the through-hole and connected to the inside of the through-hole via the supporting arch bridge, compared with the traditional design in which the end of the ratchet is connected to the ventilation window body, the two ends of the ratchet can also be fully opened, so that the gear switching resistance of each gear slot is the same or similar, improving the stability of the feel when switching gears, and thus improving the user experience.

DETAILED DESCRIPTION

[0029] In order to make the objectives, technical solutions and advantages of this application clearer, the implementation methods of this application will be further described in detail below with reference to the accompanying drawings.

[0030] With reference to the accompanying drawings, the technical solutions in the embodiments of the present application will be clearly and completely described below, obviously, the described embodiments are some of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of the present application.

[0031] As protective equipment for the head, helmets play a crucial role in motorcycle and electric bicycle riding. In addition to ensuring the safety of the rider, the comfort of the helmet is also a key performance indicator that cannot be ignored. Among them, the ventilation performance is particularly crucial for improving the comfort of the helmet: opening the ventilation function can effectively dissipate heat, remove moisture and promote air circulation, while closing the ventilation can enhance the warmth effect and isolate noise. Therefore, a well-designed, smooth-to-operate elastic ratchet type helmet ventilation window structure is essential to improve the user experience of the rider.

[0032] The common ratchet type elastic ratchet type helmet ventilation window structure on the market mainly consists of a ventilation window body and a cover plate. The ventilation window body is provided with a ratchet, and the cover plate is slid in the length direction of the ratchet through the mutual cooperation with the ratchet to realize the opening and closing of ventilation and the switching of different ventilation gears. However, when multiple ventilation gears need to be set on the ratchet, since the connection point of the ratchet and the ventilation window body is usually located at the end of its length direction, this causes the difference in the resistance encountered by the cover plate when switching different gears. Specifically, the middle gear and the gear at the end have obvious differences in hand feeling when switching, the hand feeling stability of gear switching is poor, and thus the overall user experience is affected.

[0033] To solve the above technical problems, the present embodiment provides an elastic ratchet type helmet ventilation window. Referring to Figures 1 to 3 , Figure 1 is a front perspective view of the elastic ratchet type helmet ventilation window in the embodiment of the present application, Figure 2 is a back perspective view of the elastic ratchet type helmet ventilation window in the embodiment of the present application, Figure 3 is an exploded view of the elastic ratchet type helmet ventilation window in the embodiment of the present application.

[0034] The elastic ratchet type helmet ventilation window of the present embodiment comprises a ventilation window body 1 and a push piece 2.

[0035] As Figure 2 and Figure 3As shown, the ventilation window body 1 is provided with a ventilation hole 11 and a through hole 12, and two groups of support arch bridges 13 and ratchets 14 are symmetrically arranged on opposite sides of the through hole 12. In the same group of support arch bridges 13 and ratchets 14, the support arch bridge 13 has elastic deformation capability, and the bottom is connected with the inner side of the through hole 12. The middle part of the ratchet 14 is connected with the top of the support arch bridge 13, and the two ends of the ratchet 14 are suspended in the through hole 12. At least two gear slots 15 arranged in a predetermined direction are formed between the two groups of ratchets 14, wherein the predetermined direction is the direction of the push piece 2 switching the ventilation gear.

[0036] The push piece 2 is movably connected with the ventilation window body 1 and is configured to move in a predetermined direction to block or open the ventilation hole 11, realizing the switching of the ventilation gear. The push piece 2 is provided with a gear column foot 21 which is inserted into the gear slot 15.

[0037] When switching the ventilation gear, the gear column foot 21 extrudes the two ratchets 14, so that the support arch bridge 13 elastically deforms, and then the two ratchets 14 move away from each other. The gear column foot 21 enters another adjacent gear slot 15 from a gear slot 15, and then the support arch bridge 13 resets, and the gear column foot 21 is fixed in the latter gear slot 15, so that the position of the push piece 2 relative to the ventilation window body 1 is fixed.

[0038] Exemplarily, the support arch bridge 13 and the ratchet 14 are integrally formed on the ventilation window body 1.

[0039] The installation process of the elastic ratchet type ventilation window of the above technical solution is as follows: first, positioning and fixing the ventilation window body 1: align the ventilation window body 1 with the opening on the helmet body, ensure that the position of the ventilation hole 11 is consistent with the desired ventilation direction of the rider, and then use screws or other fasteners to fix the body on the helmet body, ensure that the connection is firm and the ventilation window does not shake. Then, install the push piece 2: connect the push piece 2 with the body, align the slide rail or connecting piece on the push piece 2 with the corresponding track or slot on the body, and gently slide or rotate into place, ensuring that the push piece 2 can move smoothly in the predetermined direction, and ensuring that the gear column foot 21 is located in one of the gear slots 15.

[0040] The use principle of the elastic ratchet type helmet ventilation window is as follows: when the rider needs to adjust the ventilation amount in the helmet, the rider only needs to gently push the push piece 2, the gear column foot 21 on the push piece 2 moves along the preset direction on the ventilation window body 1, and in turn extrudes the two groups of ratchets 14. Due to the elastic deformation ability of the support arch bridge 13, the ratchets 14 are away from each other when extruded, thereby allowing the gear column foot 21 to slide from the current gear slot 15 into the adjacent gear slot 15. Changing the relative position of the push piece 2 and the ventilation window body 1 changes the area size of the push piece 2 shielding the ventilation hole 11, thereby realizing the adjustment of the ventilation amount. That is, different gear slots 15 correspond to different ventilation amounts, and when the gear column foot 21 is located in a certain gear slot 15, the opening size of the ventilation window (that is, the degree of shielding of the ventilation hole 11) will determine the ventilation amount in the helmet, and by switching different gear slots 15, the rider can adjust the ventilation effect in the helmet according to the own needs.

[0041] The principle of improving the stability of the hand feeling of the above technical solution of the elastic ratchet type helmet ventilation window is as follows: due to the fact that the two ends of the ratchet 14 are suspended in the through hole 12 and connected to the inner side of the through hole 12 through the support arch bridge 13, this structure makes the switching resistance of each gear slot 15 the same or similar when switching gears. This not only ensures the smoothness of gear switching, but also improves the consistency of the hand feeling, so that the rider can feel a more comfortable and stable experience during the operation.

[0042] In one embodiment in which the gear slots 15 are formed between the two groups of ratchets 14, as shown in Figure 2 and Figure 3 , the ratchet 14 includes a plurality of convex portions 101 and concave portions 102 alternately arranged along the preset direction, the concave portions 102 of the two ratchets 14 form the gear slot 15, and the convex portions 101 form a narrow gap that blocks the movement of the gear column foot 21. When the gear column foot 21 is pushed in the preset direction, the narrow gap is opened due to the elastic deformation of the support arch bridge 13, so that the gear column foot 21 can pass through the narrow gap and enter the adjacent gear slot 15.

[0043] For example, the convex portion 101 and the concave portion 102 are smoothly connected through a smooth arc surface, so that the movement of the gear column foot 21 between the gear slots 15 is smoother, thereby improving the operation feeling of the gear switching operation.

[0044] For example, as shown in Figure 2 and Figure 3 , three gear slots 15 are provided, the concave portion 102 in the middle of the ratchet 14 is connected to the top of the support arch bridge 13, and the concave portion 102 and the convex portion 101 at both ends of the ratchet 14 are suspended in the through hole 12. Compared with the traditional design of two gear slots 15, the additional middle gear slot 15 can realize more gear adjustment options, such as adding a gear of half-open ventilation hole 11 between the full-open and closed ventilation hole 11.

[0045] It is understandable that the number of the gear slots 15 can be increased appropriately to increase the adjustment gears. In this case, the middle portion of the ratchet 14 can correspond to a plurality of gear slots 15 .

[0046] In order to improve the stability of the push piece 2 when it moves, Figure 2 and Figure 3 As shown, the vent body 1 is provided with a slide groove 16, which is parallel to a predetermined direction; the push piece 2 is provided with a slider 22 adapted to the slide groove 16, and is movably engaged with the slide groove 16 via the slider 22. When moving, the push piece 2 can move along the slide groove 16 via the slider 22, and the slide groove 16 provides guidance and limit, thereby making the gear switching operation smoother and more stable.

[0047] For example, Figure 2 and Figure 3 As shown, the slider 22 has a hook at its end, which extends outward from the chute 16 and is restrained inside the vent body 1, preventing the slider 22 from separating from the chute 16, thereby improving the reliability of the connection between the push piece 2 and the vent body 1. The slider 22 has elastic deformation capabilities and can be inserted into the chute 16 by squeezing during installation, so that the hook extends out of the chute 16 to achieve a retaining effect.

[0048] For example, Figure 2 As shown, the slide grooves 16 are provided on both sides of the through hole 12 and are symmetrically arranged with the through hole 12 as the center. In this way, the push piece 2 can act more evenly on the ventilation window body 1 when subjected to force, thereby improving the stability of the ventilation window structure.

[0049] Illustratively, the through hole 12 and the ventilation hole 11 extend along the thickness direction of the ventilation window body 1 .

[0050] In order to facilitate the connection between the ventilation window body 1 and the helmet body, Figure 3 and Figure 3 Figure 2 Figure 3 As shown, a fixing column foot 17 is provided on the side of the ventilation window body 1 facing away from the push piece 2, and the fixing column foot 17 is used to connect to the helmet body.

[0051] Exemplarily, the fixed column foot 17 is connected to the helmet body through a connecting structure such as screws and buckles.

[0052] This embodiment provides a helmet comprising the aforementioned elastic ratchet-type helmet ventilation window and a helmet body (not shown). The ventilation window body 1 and the helmet body can be connected using existing methods or via the aforementioned fixing column feet 17. By utilizing the aforementioned elastic ratchet-type helmet ventilation window, when switching ventilation gears, the gear switching resistance of each gear slot 15 of the helmet of this embodiment is the same or similar, thereby improving the stability of the feel during gear switching and thereby enhancing the user experience.

[0053] The above merely provides the optional embodiments of the present application, and is not intended to limit the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
