Description

Technical Field

[0001] This application relates to the field of protective gear technology, and in particular to a helmet. Background Technology

[0002] Helmets are protective gear for the head and are indispensable tools for people's transportation and outdoor sports. They can protect the user's head in the event of an accident, and in order to reduce the impact of the external environment on the user during cycling or sports, many helmets are equipped with visors.

[0003] In most common helmets, the visor is rotated and mounted on the helmet body. The visor and the helmet body have multiple fixed positions through protrusions on the inner wall of the connection hole and several positioning slots. However, after long-term use, the visor and the helmet body are prone to shaking, which affects the normal use of the helmet and makes it inconvenient to assemble and repair the helmet. Summary of the Invention

[0004] Therefore, it is necessary to provide a helmet that addresses the inconvenience of assembling and repairing helmets.

[0005] This application provides a helmet, including: a helmet body (1); a visor body (21) movably mounted on the helmet body (1); an elastic cord (22) mounted on the visor body (21) and extending at least partially beyond the visor body (21) to form a mounting end; and at least one connector (23) mounted on the mounting end and configured to be detachably fixed to the helmet body (1).

[0006] In this way, by connecting the visor body to the connector via an elastic cord, a stable connection between the visor body and the helmet body can be achieved. The relative position and distance between the visor body and the helmet body can be adjusted by changing the length of the elastic cord, preventing discomfort caused by the visor body pressing on the eyes or detachment due to excessive looseness, thus improving the user experience. The detachable connection between the connector and the helmet body, with the elastic cord held in place by the connector, ensures that the elastic cord does not need to pass through the helmet body's shell. This simplifies the helmet's structure and facilitates manufacturing. Furthermore, it allows for quick separation of the visor body from the helmet body. When components such as the visor body, elastic cord, and helmet body need replacement or maintenance, the connector can be directly removed from the helmet body, allowing operators to directly replace or maintain these components and quickly reassemble them without having to pass the elastic cord through the helmet body, making helmet maintenance convenient and quick.

[0007] In one embodiment, the helmet body has a notch on the front side that matches the contour of the face mask body. The notch has a mounting groove on one of the surfaces of the face mask body and the connecting seat, and the other of the surfaces has a mounting protrusion that matches the mounting groove. The mounting protrusion can be movably inserted into the mounting groove. The helmet body also has a locking assembly configured to selectively lock the mounting protrusion into the mounting groove or release the mounting protrusion so that the mounting protrusion can be disengaged from the mounting groove.

[0008] In one embodiment, the edge of the notch is provided with a recessed fixing groove; the groove wall facing the front side of the helmet body is provided with the connecting protrusion mounting protrusion or the mounting groove.

[0009] In one embodiment, the notch is recessed inward on the surface of the face mask body to form the mounting groove, and the connecting seat is provided with a mounting protrusion; at least one of the left and right sides of the helmet body has an inwardly recessed wall to form a button groove, the button groove extending to communicate with the mounting groove; the locking assembly includes a locking member, the locking member being at least partially movably mounted in the mounting groove along the button groove, and having a first position and a second position; when the locking member is in the first position, the locking member is locked to the connecting seat; when the locking member is in the second position, the locking member is disengaged from the connecting seat.

[0010] In one embodiment, the locking component includes an elastic element supported between the locking member and the button slot, and capable of holding the locking member in a first position.

[0011] By setting the locking component to the first position, the fixing part of the locking component and the fixing position on the connecting seat are engaged to fix the two together; thus, the connecting seat and the helmet body are stably connected, and the elastic cord can be stably connected to the helmet body through the connecting seat without the elastic cord passing through the shell wall of the helmet body; when the locking component is switched to the second position, the fixing part of the locking component and the fixing position on the connecting seat are disengaged, and the connecting seat can slide out of the mounting groove on the helmet body along the second direction Y, which can facilitate the quick separation of the face mask body from the helmet body, so that the operator can directly replace and maintain the face mask body, elastic cord and helmet body, and quickly reassemble them, making helmet maintenance convenient and quick.

[0012] In one embodiment, the locking member includes a control unit and a plug-in plate extending outward from the control unit; a support wall is laterally provided in the middle of the button slot; the plug-in plate passes through the support wall along the first direction; the control unit at least partially covers the slot opening of the button slot; and the elastic member is supported between the control unit and the support wall. Thus, the control unit can be pressed by the user, overcoming the force of the elastic member, causing the plug-in plate of the locking member to reach a second position, disengaging the locking member from the connecting seat, allowing the connecting seat to slide upward along the second direction Y out of the helmet body. This facilitates quick separation of the face mask body from the helmet body, enabling quick replacement and maintenance by the operator, and rapid reassembly, making helmet maintenance convenient and quick. When the user releases the pressure, the elastic member causes the plug-in plate of the locking member to return to the first position, locking the locking member and the connecting seat together, thus maintaining a stable connection between the connecting seat and the helmet body. The elastic cord can maintain a stable connection with the helmet body through the connecting seat without passing through the shell wall of the helmet body.

[0013] In one embodiment, the plug plate has a slot formed by cutouts, and the connector passes through the slot. A fixing part protrudes from the side of the plug plate away from the control part into the slot, and the connector includes multiple fixing positions for locking with the fixing part. Thus, by setting the fixing part of the locking member and the fixing positions on the connector, when the locking member is in the first position, the fixing part and the fixing positions engage with each other to achieve fixation, ensuring a stable connection between the connector and the helmet body. By setting multiple fixing positions at intervals on the connector, the connector can be fixed in different positions within the mounting slot. This allows for adjustment of the elastic cord's tension, facilitating user adjustment of the connection between the face mask and the helmet body, preventing the elastic cord from being too tight or too loose during use and affecting the relative adjustment of the face mask and helmet body, thus improving the user experience.

[0014] In one embodiment, the side of the plug plate protrudes outward to form an elastic hook; a groove adapted to the elastic hook is formed on the side wall of the button slot. Thus, the engagement of the elastic hook and the groove effectively prevents the locking element from detaching from the helmet body, keeping them as a single unit.

[0015] In one embodiment, at least one positioning hole is formed on the helmet body, and the visor body includes a fixing protrusion that mates with the positioning hole. Thus, by engaging with the positioning hole at different positions, the fixing protrusion on the visor body allows the visor body to be fixed at different positions on the outer periphery of the helmet body, facilitating the user to adjust the position of the visor body as needed.

[0016] In one embodiment, the positioning hole is disposed on the limiting wall on the inner side of the fixing groove; and / or, the positioning hole is disposed on the wall surface on the top side of the helmet body.

[0017] In one embodiment, the connecting seat includes a connecting seat body and a roller. The roller is rotatably disposed within the connecting seat body, and two through holes are formed on one side of the connecting seat body. The end of the elastic rope passes through one of the through holes, wraps around the roller, and exits through the other through hole before connecting to the mirror body. The connecting seat body can be locked with the locking assembly. Thus, the arrangement of the two through holes and the roller facilitates the stable installation of the elastic rope and the connecting seat. Furthermore, when the elastic rope deforms, the roller effectively reduces friction between the elastic rope and the connecting seat body, allowing the elastic rope to deform evenly and improving the stress distribution on the connecting seat, thereby extending the service life of the elastic rope and the connecting seat.

[0018] In one embodiment, the connecting seat body includes C-shaped grooves formed on two side walls and a receiving groove located between the two side walls; the roller includes a wheel body and a rotating shaft fixed on the wheel body; both ends of the rotating shaft are respectively embedded in the C-shaped grooves on the two side walls; the outer circumferential surface of the roller body is concave to form an annular groove; the two through holes are located on the bottom side of the receiving groove and communicate with the receiving groove respectively. Thus, the wheel body is mounted in the receiving groove via the rotating shaft, and the end of the elastic rope can pass through the upper through hole. The annular groove on the roller can provide positioning for the elastic rope to prevent it from detaching from the roller during rotation; finally, the end of the elastic rope exits through another through hole and is reconnected to the mirror body. The roller effectively reduces friction between the elastic rope and the connecting seat body, facilitating uniform deformation of the elastic rope and improving the stress on the connecting seat, which helps extend the service life of the elastic rope and the connecting seat.

[0019] In one embodiment, at least one fixing position is formed on the outer side wall of the connector body; each fixing position includes a retaining wall and a guide surface; the guide surface is obliquely disposed on the back side of the retaining wall, and the retaining wall can be used to abut against the locking component. Thus, the guide surface facilitates quick installation and adjustment of the connector, and makes it convenient for adjusting and installing the face mask, while the retaining wall prevents accidental relative movement between the locking component and the fixing position during use, achieving a stable connection between the connector and the helmet assembly.

[0020] In one embodiment, the connector includes a positioning groove on the connector body, and a positioning protrusion adapted to the positioning groove is formed on the mask body. Thus, the positioning protrusion on the mask body is embedded in the positioning groove on the connector, serving a guiding and positioning function, preventing relative movement between the mask body and the helmet body during use, and ultimately ensuring that the mask body stably covers the human eye, providing protection.

[0021] In one embodiment, the helmet includes a connector; the connector is detachably mounted on the visor body; the end of the elastic cord enters the connector body through the first through hole, passes around the roller, exits through the second through hole, and connects to the connector. Thus, the connector facilitates stable installation of the elastic cord and the visor body, facilitates helmet assembly, and helps prevent accidental detachment of the elastic cord from the visor body during use. When the connector is removed from the visor body and the connector and connecting part are loosened, the connecting part, under its own elasticity, can reverse through the second through hole and roller of the connector body, and exit from the first through hole, allowing for quick and easy disassembly of the visor body and helmet body without disassembling the connector body and helmet body, making maintenance convenient and quick.

[0022] In one embodiment, the face mirror body includes a connecting groove and a snap-fit ​​groove. The connector includes a mounting portion that mates with the connecting groove and a snap hook that fits into the snap-fit ​​groove. A through-hole is formed in the middle of the mounting portion, and the end of the elastic cord is connected to the through-hole for tying. This achieves a detachable connection between the face mirror body and the connector.

[0023] In one embodiment, the mirror body includes a receiving groove for accommodating the connector, and both the snap-fit ​​groove and the connecting groove are disposed at the bottom of the receiving groove; wherein, the side of the connecting groove is provided with an L-shaped groove, and the side of the mounting part protrudes with a protrusion adapted to the L-shaped groove; and / or, the receiving groove forms a guide wall on the groove wall adjacent to the snap-fit ​​groove, and the hook can be guided by the guide wall and fixed in conjunction with the snap-fit ​​groove; and / or, the receiving groove forms a clearance groove above the side wall corresponding to the snap-fit ​​groove.

[0024] In one embodiment, the face mask body has a mounting channel; the mounting channel extends to both sides along the outer contour of the face mask body and forms mounting holes communicating with the outside; the middle section of the elastic rope passes through the mounting channel, and the end of the elastic rope exits from the mounting hole and is connected to the helmet body through the connector. Thus, the middle section of the elastic rope passes through the mounting channel, and one end of the elastic rope on the left exits from the mounting hole on the left side and is then connected to the connector. That is, this part of the elastic rope, as the connecting part, first passes through the through hole on the upper side of the connector body, passes around the roller, and the annular groove on the roller can provide positioning for the elastic rope. The connecting part then exits from another through hole and is reconnected to the connector fixed to the face mask body. This arrangement facilitates multi-point force distribution on the face mask body, ultimately ensuring a stable connection between the face mask body and the helmet body.

[0025] In one embodiment, several perforations communicating with the outside are formed on the sidewall of the installation channel. These perforations allow the user to easily observe the elastic rope within the installation channel and facilitate its installation. Attached Figure Description

These embodiments are only used to more clearly illustrate the technical solution of this application and are therefore merely examples, and should not be used to limit the scope of protection of this application.

[0042] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains; the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the application; the terms “comprising” and “having”, and any variations thereof, in the specification, claims, and foregoing description of the drawings are intended to cover non-exclusive inclusion.

[0043] In the description of the embodiments of this application, if the technical terms such as "first" and "second" appear, these terms are used only for descriptive purposes to distinguish different objects, and should not be construed as indicating or implying relative importance or implicitly indicating the number, specific order or primary and secondary relationship of the indicated technical features.

[0044] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0045] In the description of the embodiments in this application, the term "and / or" is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, and B existing alone. Additionally, the character " / " in this document generally indicates that the preceding and following related objects have an "or" relationship.

Similarly, if the term "multiple sets" appears, "multiple sets" refers to two or more sets (including two sets), and if the term "multiple pieces" appears, "multiple pieces" refers to two or more pieces (including two pieces).

[0047] In the description of the embodiments of this application, if the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc. appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing the embodiments of this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the embodiments of this application.

[0048] In the description of the embodiments of this application, unless otherwise explicitly specified and limited, the technical terms "installation," "connection," "joining," "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components.

Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0050] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0051] In related technologies, some helmets connect the visor to the helmet body via buckles and secure the buckles to the helmet body via elastic bands. For example, helmets with elastic bands for fixing and adjusting the visor are publicly available on the market. These helmets include a helmet body, visors, a hollow tube on the inner wall of the helmet body, elastic bands at both ends of the hollow tube, and buckles on each elastic band. Both ends of the hollow tube extend to the front of the helmet body. Each elastic band is snapped into both ends of the hollow tube. Each buckle is located on both sides of the visor and is fixedly connected to the visor.

[0052] While the above structure can stably connect the visor to the helmet body and prevent the visor from moving freely, the elastic band is prone to damage after prolonged use or under strong external force, thus affecting the normal use of the helmet. In this case, the user needs to reconnect the elastic band and buckle and insert it into the hollow tube, and the length of the elastic band cannot be too long, which makes it inconvenient to assemble and repair the helmet.

[0053] This application provides a helmet that can be used in the fields of transportation and sports; in particular, it can be used in outdoor sports such as cycling and skiing to provide protection for the eyes and head.

[0054] See Figures 1 to 15 As shown, the helmet includes: a helmet body 1, a visor body 21, an elastic cord 22, and at least one connector 23.

[0055] The visor body 21 is movably mounted on the helmet body 1. An elastic cord 22 is installed on the visor body 21 and extends at least partially beyond the visor body 21 to form a mounting end. At least one connector 23 is installed on the mounting end and configured to be detachably fixed to the helmet body 1.

[0056] The helmet body 1 is used to cover the human head and has a semi-closed cavity (not shown) inside. The outer shell of the helmet body 1 is usually made of hard plastic molding or fiberglass, and the inner lining of the helmet body 1 is usually made of impact-resistant foam, elastic sponge and other materials to provide a comfortable user experience.

[0057] A face mask 2 is movably mounted on the front end of the helmet body 1. The face mask 2 includes the aforementioned face mask body 21, elastic cord 22, and connecting seat 23. In use, the elastic cord 22 is looped onto the helmet body 1, and then the face mask body 21 is placed over the user's eyes. The face mask body 21 can be used to protect the user's eyes, for example, by preventing cold wind from irritating the eyes or by preventing ultraviolet rays from burning the eyes. When the face mask 2 is not needed, the face mask body 21 can be removed from the user's eyes, and under the restraint of the elastic cord 22, the face mask body 21 can be positioned on top of the helmet body 1 or in another location.

[0058] The face mask body 21 is connected to the connecting seat 23 via an elastic cord 22. This allows the face mask body 21 to be stably connected to the helmet body 1. The relative position and distance between the face mask body 21 and the helmet body 1 can be adjusted by adjusting the extension and retraction length of the elastic cord 22. This prevents the face mask body 21 from pressing on the human eye and causing discomfort, or from being too loose and detaching from the human eye, thus improving the user experience.

[0059] Furthermore, the connecting seat 23 is detachably connected to the helmet body 1, and the elastic rope 22 is fixed to the helmet body 1 through the connecting seat 23. This ensures that the elastic rope 22 does not need to pass through the shell wall of the helmet body 1. On the one hand, this simplifies the helmet structure and facilitates helmet production and processing. On the other hand, it allows for quick separation of the face mask body 21 from the helmet body 1. When components such as the face mask body 21, elastic rope 22, and helmet body 1 need to be replaced or maintained, the connecting seat 23 can be directly removed from the helmet body 1. Operators can then directly replace or maintain the face mask body 21, elastic rope 22, and helmet body 1, and quickly reassemble them without having to pass the elastic rope 22 through the helmet body 1, making helmet maintenance convenient and quick.

[0060] Optionally, the helmet body 1 can be streamlined, lightweight, and does not obstruct vision, or it can be spherical, depending on the design.

[0061] Optionally, the face mask body 21 has a smooth, curved design and can be embedded into the helmet body 1.

[0062] Alternatively, the elastic cord 22 may be made of rubber, nylon, or an elastic composite material.

[0063] In some embodiments, see Figures 1 to 8 As shown, the helmet includes two connecting seats 23. One connecting seat 23 can be connected to each of the left and right sides of the helmet body 1. An elastic cord 22 is threaded through the visor body 21, with both ends connected to the two connecting seats 23, and then connected to the helmet body 1 via the connecting seats 23, thus achieving a stable connection between the visor body 21 and the helmet body 1. In some other embodiments, the helmet includes only one connecting seat 23, with the connecting seat 23 only located on one side of the helmet body 1; the specific design may vary.

[0064] It should be noted that the structure of the connecting seats 23 on both sides of the helmet body 1 is usually symmetrical. Therefore, for ease of understanding, the structure is described in terms of one side only, and the structure of the other side will not be described in detail.

[0065] Unlike the previous embodiment, in some other embodiments, the helmet may include only a connecting seat 23, and one side of the helmet body 1 may be detachably connected to the elastic cord in other ways, such as directly fixing the elastic cord 22 to the shell of the helmet body 1 with bolts, without the elastic cord 22 passing through the shell of the helmet body 1; the other side of the helmet body 1 may be provided with a connecting seat 23, and thus the connecting seat 23 and the elastic cord 22 may be stably connected to the face mask body 21.

[0066] In some possible embodiments, see Figures 1 to 15 As shown, the helmet body 1 has a notch on its front side that matches the contour of the face mirror body 21. A mounting groove 12 is provided on one of the surfaces of the notch facing the face mirror body 21 and the connecting seat 23. The other surface has a mounting protrusion that matches the mounting groove 12, and the mounting protrusion can be movably inserted into the mounting groove. The helmet body 1 also has a locking assembly configured to selectively lock the mounting protrusion into the mounting groove 12 or release the mounting protrusion so that it can disengage from the mounting groove 12.

[0067] Specifically, when the mounting protrusion is inserted into the mounting groove 12, the connecting seat 23 and the helmet body 1 can be positioned. The mounting protrusion is selectively locked into the mounting groove 12 by the locking component, thereby fixing the connecting seat 23 and the helmet body 1. The connecting seat 23 is then connected to the helmet body 1, achieving a stable connection between the visor body 21 and the helmet body 1. The mounting protrusion can be selectively released by the locking component, allowing it to disengage from the mounting groove 12. This enables the helmet body 1 to quickly separate from the connecting seat 23, and consequently, the visor 2 to quickly separate from the helmet body 1, facilitating rapid maintenance of the visor body 21, the elastic cord 22, and the helmet body 1 by the user.

[0068] It should be noted that the entirety of the connector 23 or at least a portion of the connector 23 serves as a mounting protrusion, thus providing a corresponding mounting groove 12 on the surface of the notch facing the mirror body 21; similarly, a mounting protrusion can be formed by directly protruding outward on the surface of the notch facing the mirror body 21, thus forming a mounting groove 12 by recessing inward on the surface of the connector 23.

[0069] In some possible embodiments, see Figures 1 to 15 As shown, a recessed fixing groove 11 is constructed along the edge of the notch; the groove wall facing the front side of the helmet body 1 is provided with a mounting protrusion or mounting groove 12.

[0070] Thus, when the mounting groove 11 has a mounting protrusion on the groove wall facing the front side of the helmet body 1, the surface of the connecting seat 23 is recessed inward to form the mounting groove 12; when the mounting groove 11 has a mounting groove 12 on the groove wall facing the front side of the helmet body 1, the entire connecting seat 23 or at least a part of the connecting seat 23 serves as the mounting protrusion.

[0071] It should be noted that, regardless of whether the mounting groove 12 or the mounting protrusion is provided on the connector 23, the mounting protrusion can be movably inserted into the mounting groove 12; and the locking or separation described above can be achieved by the locking component.

[0072] For ease of understanding, in the following embodiments, the mounting protrusion is located on the connector 23 and the notch faces the surface of the mirror body 21, and a mounting groove 12 is provided.

[0073] In some possible embodiments, see Figures 1 to 5 As shown, the helmet body 1 has an installation area on at least one of its left and right sides. The helmet includes a locking component, which is at least partially located on the installation area and can selectively lock the connector 23 to the installation area or release the connector 23 to separate it from the installation area.

[0074] It should be noted that in various embodiments of this application, the helmet body 1 is used to cover the human head. According to the front, back, left and right sides of the human head, the helmet body 1 also has a corresponding front end, rear end, left side and right side. The left and right sides of the helmet body 1 correspond to the human ear and the surrounding area, the front end of the helmet body 1 corresponds to the human forehead and the surrounding area, and the rear end of the helmet body 1 corresponds to the human back of the head and the surrounding area. Therefore, in various embodiments of this application, unless otherwise specified, the various positions of the helmet body 1 are determined by the above-mentioned corresponding parts of the human body.

[0075] The locking component is at least partially located on the mounting area. The locking component can selectively lock the connector 23 to the mounting area, thereby facilitating the connection of the elastic cord 22 to the connector 23, and then connecting the connector 23 to the helmet body 1, thus achieving a stable connection between the visor body 21 and the helmet body 1. The locking component can also selectively release the connector 23 to separate it from the mounting area, allowing the helmet body 1 to be quickly separated from the connector 23, and thus the visor 2 to be quickly separated from the helmet body 1, facilitating quick maintenance of the visor body 21, elastic cord 22, and helmet body 1 by the user.

[0076] Alternatively, the locking component can be a latch structure, a ball-locking structure, or a bolt connection structure.

[0077] In some possible embodiments, see Figure 2 , Figures 5 to 7 ,as well as Figures 12 to 15 As shown, a mounting groove 12 is recessed inward on the surface of the face mirror body 21 with a notch facing it, and a mounting protrusion is provided on the connecting seat 23; a button groove 13 is formed by recessing inward on at least one of the left and right sides of the helmet body 1, and the button groove 13 extends to communicate with the mounting groove 12. The locking assembly includes a locking member 3, which is at least partially movably mounted in the mounting groove along the button groove 13, and has a first position and a second position; when the locking member 3 is in the first position, the locking member 3 is locked to the connecting seat 23; when the locking member 3 is in the second position, the locking member 3 is released from the connecting seat 23.

[0078] Specifically, at least one of the left and right sides of the helmet body 1 has a recessed wall surface along a first direction X to form a button groove 13, where the first direction X is the left and right direction of the helmet body 1; the mounting groove 12 communicates with the button groove 13. The locking member 3 is movably disposed in the button groove 13 of the helmet body 1 and has a first position and a second position.

[0079] When the locking member 3 is in the first position, the locking member 3 locks with the connecting seat 23. In this way, the mounting protrusion of the connecting seat 23 can be locked into the mounting groove 12 of the helmet body 1 by the locking member 3, thereby fixing the connecting seat 23 and the helmet body 1, and then connecting it to the helmet body 1 by the connecting seat 23, thereby achieving a stable connection between the face mask body 21 and the helmet body 1.

[0080] When the locking member 3 is in the second position, the locking member 3 is disengaged from the connecting seat 23. Thus, the locking member 3 being in the second position releases the restriction of the connecting seat 23, allowing the mounting protrusion of the connecting seat 23 to disengage from the mounting groove 12 of the helmet body 1. This allows the helmet body 1 to be quickly separated from the connecting seat 23, and consequently, the visor 2 to be quickly separated from the helmet body 1, facilitating quick maintenance of the visor body 21, the elastic cord 22, and the helmet body 1 by the user.

[0081] Continue reading Figure 2 , Figures 5 to 7 ,as well as Figures 12 to 15 As shown, the locking assembly also includes an elastic element 4. The elastic element 4 is supported between the locking element 3 and the button groove 13, and enables the locking element 3 to remain in the first position.

[0082] Combination Figure 6 and Figure 7 As shown, a button groove 13 is formed in the mounting area on the left side of the helmet body 1. The button groove 13 is usually a blind hole and has a certain depth to the left along the first direction X to facilitate the movable installation of the locking member 3 in the button groove 13.

[0083] The elastic element 4 is supported between the locking element 3 and the button groove 13 of the helmet body 1. The elastic element 4 can be a tension spring, compression spring, coil spring, or a structure such as a pull cord that can provide force; thus, the elastic element 4 can act on the locking element 3 to keep the locking element 3 in a first position; that is, when the locking element 3 is in the first position, the elastic element 4 can provide it with a holding force to keep it in the first position; when the locking element 3 is in the second position, the elastic element 4 can provide it with a driving force to move towards the first position.

[0084] See Figures 12 to 15 As shown, and in specific combination Figure 5 The indicated direction Figure 5 The locking member 3 is in the first position. At this time, the fixing part 33 (mentioned below) of the locking member 3 and the fixing position 234 (mentioned below) on the connecting seat 23 are engaged with each other to fix the two. The locking member 3 is provided in the helmet body 1, so that the connecting seat 23 and the helmet body 1 are stably connected. The elastic rope 22 can be stably connected to the helmet body 1 through the connecting seat 23 without the elastic rope 22 passing through the shell wall of the helmet body 1.

[0085] When it is necessary to detach the connecting seat 23 from the helmet body 1, the locking member 3 can be switched to the second position, combined with... Figure 5 The second position is to Figure 5 The locking member 3 moves to the left and bottom along the first direction X, so that the fixing part 33 of the locking member 3 is disengaged from the fixing position 234 on the connecting seat 23. At this time, without the restriction of the locking member 33, the connecting seat 23 can slide upward and out of the mounting groove 12 on the helmet body 1 along the second direction Y, which can facilitate the quick separation of the face mask body 21 from the helmet body 1. This allows the operator to directly replace and maintain the face mask body 21, elastic rope 22 and helmet body 1, and quickly reassemble them, making helmet maintenance convenient and quick.

[0086] In some possible embodiments, see Figures 5 to 7 ,as well as Figures 12 to 15 As shown, the locking member 3 includes a control part 31 and a plug plate (not shown) extending outward from the control part 31; a support wall 132 is provided laterally in the middle of the button groove 13; the plug plate passes through the support wall 132 along the first direction X until it reaches the bottom of the button groove 13; the control part 31 at least partially covers the opening of the button groove 13; and the elastic member 4 is supported between the control part 31 and the support wall 132.

[0087] The control unit 31 can be pressed by the user to overcome the force of the elastic member 4, so that the plug plate of the locking member 3 reaches the second position, the locking member 3 disengages from the connecting seat 23, and the connecting seat 23 can slide out of the helmet body 1 along the second direction Y. This facilitates the quick separation of the face mask body 21 from the helmet body 1, allowing the operator to quickly replace and maintain the helmet, and then quickly reassemble it, making helmet maintenance convenient and quick.

[0088] When the user releases the pressure, the elastic element 4 can cause the plug plate of the locking element 3 to return to the first position, so that the locking element 3 and the connecting seat 23 lock each other, thereby making the connecting seat 23 and the helmet body 1 maintain a stable connection. The elastic rope 22 can maintain a stable connection with the helmet body 1 through the connecting seat 23 without the elastic rope 22 passing through the shell wall of the helmet body 1.

[0089] The support wall 132 is typically integrally formed with the button slot 13, and the support wall 132 has a crack or notch (not shown) through which the plug plate can move. Figure 5 As shown, with the support wall 132 as the boundary, the support wall 132 can divide the button slot 13 into a first space on the left (not shown) and a second space on the right (not shown); the first space and the second space are connected through cracks or holes on the support wall 132.

[0090] The button slot 13 is typically formed in the inward-facing side of the mounting area of ​​the helmet body 1; Figure 5 In the middle, the plug plate passes through the slot opening of the button slot 13 in sequence along the first direction X to the left, passes through the first space, and passes through the support wall 132 until it reaches the bottom of the second space of the button slot 13; the part of the plug plate located in the second space can cooperate with the connector 23, so as to selectively lock or release the connector 23.

[0091] The control unit 31 at least partially covers the opening of the button slot 13, thereby blocking the mating structure between the locking component and the helmet body 1 and preventing debris from falling in.

[0092] The elastic element 4 is supported between the control part 31 and the support wall 132, thereby enabling the locking element 3 to remain in the first position.

[0093] Optionally, the control unit 31 can be formed using materials such as ABS plastic, polytetrafluoroethylene, aluminum alloy, and copper alloy; the plug-in plate can also be formed using materials such as ABS plastic, polytetrafluoroethylene, aluminum alloy, and copper alloy. The control unit 31 and the plug-in plate can be an integral structure; or they can be processed separately and then fixed together by welding.

[0094] In some possible embodiments, see Figures 1 to 15 As shown, the locking member 3 should be concealed within the button groove 13. This involves controlling the depth of the button groove 13, the thickness of the control part 31, and the length of the connector plate; ensuring that when the locking member 3 is in the second position, the control part 31 is lower than the opening of the button groove 13; and when the locking member 3 is in the first position, the control part 31 is flush with or slightly recessed from the opening of the button groove 13; thus ensuring that the locking member 3 will not protrude from the inner wall of the helmet body 1 in either position. In this way, on the one hand, during helmet use, the concealed recessed design can effectively prevent the locking member 3 from being accidentally triggered, thereby avoiding accidental separation of the visor 2 from the helmet body 1, which is beneficial for the stable installation of the connector 23 and the helmet body 1. On the other hand, during normal helmet use, users can avoid scratches or injuries caused by the protruding control part 31 of the locking member 3, improving the user experience.

[0095] In some possible embodiments, see Figures 5 to 7 ,as well as Figures 12 to 15 As shown, a slot 32 is formed in the plug plate, and the connector 23 passes through the slot 32; a fixing part 33 is formed on the side of the plug plate away from the control part 31 that protrudes into the slot 32, and the connector 23 includes a plurality of fixing positions 234 for engaging and locking with the fixing part 33 of the connector 23.

[0096] Thus, by setting the fixing part 33 of the locking member 3 and the fixing position 234 on the connecting seat 23, when the locking member 3 is in the first position, the fixing part 33 and the fixing position 234 fit together to fix the two, ensuring that the connecting seat 23 and the helmet body 1 maintain a stable connection.

[0097] Multiple fixing positions 234 are spaced apart on the side of the connecting seat 23 facing the fixing part 33. This allows the connecting seat 23 to move within the mounting groove 12, enabling the fixing part 33 of the locking member 3 to engage with different fixing positions 234. For details, please refer to... Figure 5 As shown, the locking member 3 is in the first position, and the fixing part 33 of the locking member 3 engages with the first fixing position 234 on the connecting seat 23 to fix the two together; when the operator further pushes the connecting seat 23 downward along the second direction Y, the fixing part 33 of the locking member 3 engages with the second fixing position 234 on the connecting seat 23, and so on; in this way, the connecting seat 23 can be fixed in different positions of the mounting groove 12; thereby, the tightness of the elastic rope 22 can be adjusted, which is convenient for the user to adjust the connection between the face mask body 21 and the helmet body 1, and avoids the elastic rope 22 being too tight or too loose during use, which will affect the relative adjustment of the face mask body 21 and the helmet body 1, thus improving the user experience.

[0098] Optionally, the fixing position 234 can be a positioning rack structure, groove structure, or protrusion structure; the fixing part 33 can be a rack, protrusion, or groove that cooperates with it.

[0099] In some possible embodiments, see Figure 7 , Figure 14 as well as Figure 15 As shown; the side of the plug plate protrudes outward to form an elastic hook 34; the side wall of the button groove 13 has a hook groove 131 that matches the elastic hook 34.

[0100] Thus, the engagement of the elastic hook 34 and the hook groove 131 effectively prevents the locking member 3 from detaching from the helmet body 1, keeping them as one unit. When the fixing part 33 of the plug plate of the locking member 3 engages with the fixing position 234 on the connecting seat 23, the two are fixed together, thus maintaining the connection between the helmet body 1 and the connecting seat 23. By locking or releasing the connecting seat 23 with the locking member 3, the helmet body 1 can be quickly separated from the connecting seat 23, thereby allowing the visor 2 to be quickly separated from the helmet body 1, facilitating rapid helmet maintenance for the user.

[0101] Combination Figure 7The hook groove 131 is located at the bottom of the button groove 13. The vertical width of the hook groove 131 is greater than the vertical width of the rest of the button groove 13. During the process of inserting the plug plate into the button groove 13, the elastic hook 34 can be compressed by its own inclined surface. When the elastic hook 34 reaches the bottom of the button groove 13, the elastic hook 34 restores its shape and remains connected with the hook groove 131.

[0102] The depth of the groove 131 along the first direction X should be greater than the thickness of the elastic hook 34, so that the locking member is movably disposed in the button groove 13 of the helmet body 1, and has a first position and a second position; the elastic member 4 is supported between the locking member 3 and the button groove 13. The locking member 3 has a tendency to move to the right along the first direction X in the first position, and maintains a stable connection through the hook groove 131 and the elastic hook 34. When the locking member 3 moves to the second position under the action of external force, the elastic hook 34 moves along the first direction X. Figure 7 The left side of the groove 131 shown in the figure moves, but the elastic hook 34 is still within the range of the groove 131. At this time, the locking member 3 is disengaged from the connecting seat 23.

[0103] Optionally, the portion of the plug-in plate adjacent to the elastic hook 34 is also provided with a process groove (not shown) to facilitate the deformation of the elastic hook 34 and to facilitate the insertion of the plug-in plate of the locking member 3 into the button slot 13.

[0104] In some possible embodiments, see Figures 1 to 15 As shown, a fixing groove 11 and a mounting groove 12 are formed on the helmet body 1.

[0105] A notch (not shown) is formed on the front wall of the helmet body 1; a fixing groove 11 is provided at the edge of the notch and extends along the notch to the mounting areas on both sides. A mounting groove 12 is provided on the side wall of the mounting area corresponding to the fixing groove 11. The mounting groove 12 extends inward along the second direction Y and communicates with the button groove 13; the second direction Y is the front-rear direction of the helmet body 1; the connecting seat 23 is movably provided in the mounting groove 12 and can be locked with the locking member 3.

[0106] The helmet body 1 is used to cover the head of the human body. The notch on the front wall of the helmet body 1 should be able to fit the human eye, that is, the shape and outline should be roughly the same as the eye. The fixing groove 11 should match the outer outline of the mask body 21 along the overall extension direction of the notch to both sides. This allows the mask body 21 to be embedded in the fixing groove 11 of the notch when it is located at the front of the helmet body 1.

[0107] The connecting seat 23 can be inserted into the mounting groove 1 on the helmet body 1 along the second direction Y, and locked by the locking member 3 in the first position, thereby achieving a stable connection between the connecting seat 23 and the helmet body 1. The elastic rope 22 can be stably connected to the helmet body 1 through the connecting seat 23 without the elastic rope 22 passing through the shell wall of the helmet body 1.

[0108] When the locking member 3 is switched to the second position, the fixing part 33 of the locking member 3 disengages from the fixing position 234 on the connecting seat 23, so that the connecting seat 23 can slide out of the mounting groove 12 on the helmet body 1 along the second direction Y. In this way, the face mask body 21 can be quickly separated from the helmet body 1, so that the operator can directly replace and maintain the face mask body 21, elastic rope 22 and helmet body 1, and quickly reassemble them, making helmet maintenance convenient and quick.

[0109] In some possible embodiments, see Figures 1 to 4 , Figure 6 as well as Figure 8 As shown, at least one positioning hole 112 is formed on the helmet body 1. The face mask body 21 includes a fixing protrusion 212 that is adapted to the positioning hole 112.

[0110] For example, one of the positioning holes 112 may be provided on the limiting wall 111 on the inner side of the fixing groove 11.

[0111] For example, one of the positioning holes 112 may be provided on the top side wall of the helmet body 1. The top side wall of the helmet body 1 corresponds to the top of the human head and the surrounding area.

[0112] Depending on the needs, the helmet body 1 may have only one positioning hole 112, or multiple positioning holes 112 may be set in different areas as needed.

[0113] The positioning hole 112 can be a groove structure, and the fixing protrusion 212 is a protrusion structure that mates with it. The helmet body 1 has at least two or more positioning holes 112. All positioning holes 112 are arranged sequentially from front to back on the outer surface of the helmet body 1 away from the receiving cavity. The fixing protrusion 212 on the visor body 21, by engaging with the positioning holes 112 at different positions, allows the visor body 21 to be fixed at different positions on the outer circumference of the helmet body 1, facilitating the user to adjust the position of the visor body 21 as needed.

[0114] Specifically, in combination Figures 1 to 3As shown, one of the positioning holes 112 is provided on the limiting wall 111 on the inner side of the fixing groove 11. When the user needs to use the helmet visor 2 to protect his eyes, the visor body 21 can be moved onto the fixing groove 11. At least part of the outer contour of the visor body 21 can be fitted and positioned with the fixing groove 11. The fixing protrusion 212 on the visor body 21 is inserted into the positioning hole 112 on the limiting wall 111 on the inner side of the fixing groove 11. The visor body 21 and the helmet body 1 are then stably connected by the elastic rope 22 and the connecting seat 23, thereby ensuring that the visor body 21 can stably cover the human eye and provide protection.

[0115] Combination Figure 1 , Figure 2 and Figure 4 As shown, when the user does not need the visor body 21 to cover the eyes, the visor body 21 can be moved along the outer periphery of the helmet body 1 to the rear end, and fixed with the fixing protrusion 212 on the visor body 21 through the positioning hole 112. Then, the visor body 21 and the helmet body 1 are kept stably connected by the elastic rope 22 and the connecting seat 23, ensuring that the visor body 21 can maintain a stable connection with the helmet body 1.

[0116] Optionally, the fixing protrusion 212 is provided on the inner side of the visor body 21 facing the receiving cavity of the helmet body 1; see reference Figure 8 The fixing protrusion 212 is located in the middle of the visor body 21. The two sides of the visor body 21 can be connected to the helmet body 1 by elastic cords 22, thereby ensuring that the visor body 21 can maintain a stable connection with the helmet body 1.

[0117] In some possible embodiments, see Figure 1 , Figure 2 , Figures 11 to 13 As shown; the connecting seat 23 includes a connecting seat body 231 and a roller 232. The roller 232 is rotatably disposed inside the connecting seat body 231. Two through holes 235 are formed on one side of the connecting seat body 231. The connecting seat body 231 can be locked with the locking component.

[0118] The main body 231 of the connector can be a hollow square shell structure, and the main body 231 is provided through the front and rear sides, and is formed by connecting the top surface (not shown), the bottom surface (not shown), and two opposite side walls (not shown). The main body 231 of the connector can be made of materials such as ABS plastic, polytetrafluoroethylene, aluminum alloy, and copper alloy.

[0119] The connector body 231 extends through the front and rear sides and is movably inserted into the mounting groove 12 along the second direction Y. Furthermore, multiple fixing positions 234 are provided on the side wall of the connector body 231 to facilitate locking with the locking component at different positions.

[0120] When the elastic rope 22 is specifically connected to the connecting seat 23, the elastic rope 22 is usually threaded on the mirror body 21. The end of the elastic rope 22 can be inserted into one of the holes 235, pass around the roller 232 and exit from the other hole 235, and be reconnected to the mirror body 21. In this way, the arrangement of the two holes 235 and the roller 232 facilitates the stable installation of the elastic rope 22 and the connecting seat 23. When the elastic rope 22 deforms, the roller 232 can effectively reduce the friction between the elastic rope 22 and the connecting seat body 231, so that the elastic rope 22 can deform evenly and improve the stress on the connecting seat 23, which is beneficial to extending the service life of the elastic rope 22 and the connecting seat 23.

[0121] In some possible embodiments, see Figure 1 , Figure 2 , Figures 11 to 13 As shown, the main body 231 of the connecting seat includes a receiving groove 2311 located between two side walls and C-shaped grooves 236 formed on the two side walls respectively; the roller 232 includes a wheel body and a rotating shaft 2322 fixed on the wheel body; the two ends of the rotating shaft 2322 are respectively embedded in the C-shaped grooves 236 on the two side walls; the outer peripheral surface of the wheel body of the roller 232 is concave to form an annular groove 2321; two through holes 235 are located on the bottom side of the receiving groove 2311 and are respectively connected to the receiving groove 2311.

[0122] Thus, combined Figure 11 and Figure 12 As shown, the wheel is mounted in the storage groove 2311 via a rotating shaft 2322. The end of the elastic rope 22 can be inserted into the upper perforation 235. The annular groove 2321 on the roller 232 can provide positioning for the elastic rope 22 to prevent the elastic rope 22 from detaching from the roller 232 during rotation. Finally, the end of the elastic rope 22 exits through another perforation 235 and is reconnected to the mirror body 21. The roller 232 can effectively reduce the friction between the elastic rope 22 and the connecting seat body 231, which facilitates the uniform deformation of the elastic rope 22 and improves the stress on the connecting seat 23, thus extending the service life of the elastic rope 22 and the connecting seat 23.

[0123] In some possible embodiments, see Figure 5 , Figures 12 to 15 As shown, at least one fixing position 234 is formed on the outer side wall of the connecting seat body 231 for locking with the locking member 3 of the locking assembly.

[0124] Each fixing position 234 is a long toothed structure, and each fixing position 234 includes a clamping wall 2342 and a guide surface 2341; the guide surface 2341 is inclinedly disposed on the back side of the clamping wall 2342, and the clamping wall 2342 can be used to abut against the locking component.

[0125] Specifically, the fixing position 234 includes a guide surface 2341 and abutting wall 2342; one end of the guide surface 2341 and the abutting wall 2342 are connected, and the other end of the guide surface 2341 and the abutting wall 2342 respectively extend to the side wall surface of the connecting seat body 231 of the connecting seat 23, so that the fixing position 234 is formed into an elongated rack structure. The guide surface 2341 is inclined, and the abutting wall 2342 is vertical. The fixing part 33 on the locking member 3 can also be configured with a tooth shape that can engage with it.

[0126] Combination Figure 5 When the operator pushes the connecting seat 23 downward along the second direction Y, the guide surface 2341 meets the fixing part 33 and can abut against the fixing part 33 of the locking member 3. Due to the effect of the inclined surface, the guide surface 2341 can convert the action along the second direction Y into the action of driving the locking member 3 to move to the second position, so that the connecting seat 23 can quickly reach the depth required along the second direction Y. After the operator stops pushing, the fixing part 33 of the locking member 3 can quickly cooperate with the fixing position 234 corresponding to the current depth.

[0127] Similarly, when the operator or external force pulls the connecting seat 23 upward along the second direction Y, a clamping wall 2342 is provided on the other side of the fixed position 234. The clamping wall 2342 abuts against the fixed part 33 of the locking member 3. Since the clamping wall 2342 is vertically set, the locking member 3 is effectively prevented from shifting, thereby preventing the connecting seat 23 from falling out of the mounting groove 12.

[0128] Thus, the guide surface 2341 facilitates the quick installation and adjustment of the connecting seat 23 and the adjustment and installation of the face mask 2, while the clamping wall 2342 prevents the locking part 3 from accidentally moving relative to the fixing position 234 during use, thereby achieving a stable connection between the connecting seat 23 and the helmet assembly 1.

[0129] In some possible embodiments, see Figure 5 , Figure 8 , Figure 9 ,as well as Figures 11 to 13 As shown; the connector 23 includes a positioning groove 233 disposed on the connector body 231, and a positioning protrusion 211 adapted to the positioning groove 233 is formed on the mirror body 21.

[0130] Combination Figure 11 The bottom side of the storage groove 2311 of the connector body 231 has a base plate (not shown). The base plate is set on the front side of the connector body 231 and is connected to two side walls respectively. A through hole 235 is formed on the upper side and the lower side of the base plate respectively.

[0131] A positioning groove 233 is recessed inward from the base plate, and a positioning protrusion 211 is formed on the visor body 21 to match the positioning groove 233. When the user needs to use the helmet visor 2 to protect their eyes, the visor body 21 can be moved onto the fixing groove 11. At least part of the outer contour of the visor body 21 can be fitted and positioned with the fixing groove 11. The fixing protrusion 212 on the visor body 21 is embedded into the positioning hole 112 on the limiting wall 111 located on the inner side of the fixing groove 11. Then, through the elastic contraction of the elastic rope 22, the positioning protrusion 211 is driven to cooperate with the positioning groove 233, so that the positioning protrusion 211 on the visor body 21 is embedded into the positioning groove 233 on the connecting seat 23, which plays a guiding and positioning role, preventing the visor body 21 and the helmet body 1 from moving relative to each other during use, so that the visor body 21 can stably cover the human eye and provide protection.

[0132] In some possible embodiments, see Figure 1 , Figure 2 , Figures 11 to 13 As shown; the end of the elastic rope 22 is a connecting part 221; the connecting part 221 is U-shaped and is wound around the roller 232.

[0133] The two ends of the U-shaped connecting part 221 are respectively connected to the mask body 21, and the middle part of the U-shaped connecting part 221 is wrapped around the roller 232 in the connecting seat 23. By setting the U-shaped connecting part 221, it is beneficial for the mask body 21 to bear force at multiple points, thereby facilitating the stable installation of the mask body 21 and the helmet body 1.

[0134] Specifically, the connecting part 221 passes through the mounting hole 213 (mentioned below) on the mirror body 21, enters the connecting seat body 231 through the first through hole 235, passes through the second through hole 235 around the roller 232, and then reconnects to the mirror body 21; the reconnection method can be to fix it by tying a rope or by fixing it with bolts.

[0135] The elastic rope 22 is connected to the mirror body 21 and the connecting seat 23 by a U-shaped structure. The connecting part 221 can effectively cooperate with the two through holes 235 and the roller 232. When the elastic rope 22 deforms, the roller 232 can effectively reduce the friction between the elastic rope 22 and the connecting seat body 231, so that the elastic rope 22 can deform evenly and improve the stress on the connecting seat 23, which is conducive to extending the service life of the elastic rope 22 and the connecting seat 23.

[0136] In some possible embodiments, the helmet includes a connector 24; the connector 24 is detachably mounted on the visor body 21. The end of the elastic cord 22 enters the connector body 231 through a first perforation 235, passes around a roller 232, exits through a second perforation 235, and connects to the connector 24.

[0137] Specifically, the end of the elastic rope 22, namely the connecting part 221, passes through the mounting hole 213 on the mirror body 21, enters the connecting seat body 231 through the first through hole 235, passes through the roller 232 through the second through hole 235, and then reconnects to the connector 24 fixed to the mirror body 21; thereby ensuring that the end of the elastic rope 22 can stably connect the mirror body 21 and the connecting seat 23.

[0138] The connector 24 is detachably mounted on the face frame (mentioned below) of the face mask body 21; the connection method can be snap-fit ​​or bolt connection. The connector 24 facilitates the stable installation of the elastic cord 22 and the face mask body 21, facilitates the assembly of the helmet, and helps to prevent the elastic cord 22 from accidentally detaching from the face mask body 21 during use; when the connector 24 on the face mask body 21 is removed and the connector 24 and the connecting part 221 are loosened, the connecting part 221 can move backward through the second through hole 235 and the roller 232 of the connecting seat 23 under its own elasticity, and exit from the first through hole 235. In this way, the face mask body 21 and the helmet body 1 can be quickly disassembled without disassembling the connecting seat 23 and the helmet body 1, making maintenance convenient and quick.

[0139] In some possible embodiments, see Figures 8 to 10 As shown, the main body 21 of the face mirror includes a connecting groove 215 and a snap-fit ​​groove 216. The connector 24 includes a mounting part 242 that mates with the connecting groove 215 and a snap hook 244 that mates with the snap-fit ​​groove 216. A through limiting hole 241 is formed in the middle of the mounting part 242, and the end of the elastic rope 22 is connected to the limiting hole 241.

[0140] The connector 24 includes a plate for embedding into the connecting groove 215 and the snap-fit ​​groove 216, and a mounting portion 242 protruding from the plate; a snap hook 244 is provided on the far end of the mounting portion 242 in the plate and protrudes from the plate surface.

[0141] The hook 244 engages with the locking groove 216 to prevent the mounting part 242 from disengaging from the connecting groove 215, keeping the connector 24 and the mask body 21 relatively fixed, thus achieving a detachable connection between the mask body 21 and the connector 24. The elastic cord 22 passes through the limiting hole 241, and the end of the elastic cord 22 is knotted, effectively preventing the connecting cord from disengaging from the connector 24. This allows for a stable connection between the elastic cord 22 and the mask body 21. The connector 24 facilitates the stable installation of the elastic cord 22 and the mask body 21, making helmet assembly easier and preventing accidental disengagement of the elastic cord 22 from the mask body 21 during use, thus providing convenience for the user.

[0142] Alternatively, the connector 24 may be formed from materials such as ABS plastic, polytetrafluoroethylene, aluminum alloy, or copper alloy.

[0143] In some possible embodiments, see Figures 8 to 10 As shown, the mirror body 21 includes a receiving groove 210 for accommodating the connector 24, and a snap-fit ​​groove 216 and a connecting groove 215 are both provided at the bottom of the receiving groove 210. The connecting groove 215 has an L-shaped groove 218 on its side, and the mounting part 242 has a protrusion 243 on its side that matches the L-shaped groove 218.

[0144] Thus, the connector 24 is placed into the receiving groove 210, the mounting part 242 is inserted downward into the connecting groove 215, and the protrusion 243 is inserted into the vertical section groove of the L-shaped groove 218. By rotating a certain angle around the central axis of the mounting part 242, the plate of the connector 24 can be rotated into the snap-fit ​​groove 216 and fixed by the snap hook 244, and the protrusion 243 is inserted into the horizontal section groove of the L-shaped groove 218, ensuring that the connector 24 and the mirror body 21 are fixedly connected in the axial direction.

[0145] Optionally, two L-shaped grooves 218 can be symmetrically arranged on the side of the connecting groove 215 to facilitate the connection of the connector 24 to the receiving groove 210 from both sides, ensuring uniform force distribution.

[0146] In some possible embodiments, see Figures 8 to 10 As shown, the receiving groove 210 has a guide wall 217 formed on the adjacent groove wall of the snap-fit ​​groove 216. The snap hook 244 can be guided by the guide wall 217 and fixed in place with the snap-fit ​​groove 216. During the rotation of the plate of the connector 24 toward the snap-fit ​​groove 216, the snap hook 244 can be guided by the guide wall 217 and fixed in place with the snap-fit ​​groove 216, making assembly and disassembly more convenient.

[0147] In some possible embodiments, see Figures 8 to 10 As shown, a clearance groove 219 is formed on the upper side wall of the receiving groove 210 corresponding to the snap-fit ​​groove 216. After the plate of the connector 24 is rotated into position in the snap-fit ​​groove 216, the plate of the connector 24 and the snap-fit ​​groove 216 are engaged. The user can apply force to the connector 24 through the clearance groove 219, thereby driving it to rotate in the opposite direction, thereby driving the hook 244 to disengage from the snap-fit ​​groove 216.

[0148] In some possible embodiments, see Figures 8 to 10 As shown, the face mirror body 21 includes a lens (not shown) and a face frame (not shown) surrounding the lens.

[0149] The face mask body 21 has a mounting channel (not shown); the mounting channel extends to both sides along the outer contour of the face mask body 21 and forms mounting holes 213 that connect to the outside. The middle section of the elastic cord 22 passes through the mounting channel, and the end of the elastic cord 22 passes through the mounting hole 213 and is connected to the helmet body 1 through the connecting seat 23.

[0150] Specifically, the interior of the face frame of the face mirror body 21 is hollow, thus forming an installation channel; the installation channel extends to both sides along the outer contour of the face frame, facilitating the installation of the elastic cord 22.

[0151] Specifically, see Figures 8 to 10 and combined Figure 1 , Figure 2 , Figures 11 to 13 As shown, the middle section of the elastic rope 22 is inserted into the installation channel, and one end of the elastic rope 22 on the left side passes through the mounting hole 213 on the left side and is then connected to the connecting seat 23. That is, this part of the elastic rope 22, as the connecting part 221, first passes through the through hole 235 on the upper side of the connecting seat body 231, and then passes around the roller 232. The annular groove 2321 on the roller 232 can provide positioning for the elastic rope 22. The connecting part 221 then passes through another through hole 235 and is reconnected to the connector 24 fixed on the face mask body 21. In this way, the face mask body 21 is subjected to multiple forces, and finally the stable connection between the face mask body 21 and the helmet body 1 is ensured.

[0152] It should be noted that the connection structure and method of one end of the elastic rope 22 on the right side can be the same as that on the left side, and this application will not elaborate on this further.

[0153] By providing connecting seats 23 on both sides of the face mask body 21, the elastic rope 22 passes through the mounting hole 213 and connects to the connecting seats 23 on both sides respectively, which facilitates even force distribution on both sides of the face mask body 21, thereby ensuring a stable connection between the face mask body 21 and the helmet body 1. In addition, the middle section of the elastic rope 22 is stored in the mounting channel, which can effectively increase the deformation of the elastic rope 22, making it convenient for the user to adjust the relative position of the face mask body 21 and the helmet body 1.

[0154] In some possible embodiments, see Figure 8 As shown, several open sections 214 communicating with the outside are formed on the side wall of the installation channel. The open sections 214 make it easy for the user to observe the elastic rope 22 in the installation channel and facilitate the installation of the elastic rope 22.

[0155] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0156] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
