[0010] In one embodiment, the locking assembly includes an elastic member. The elastic member is supported between the locking member and the button groove and can keep the locking member in the first position.

[0011] By setting the locking member in the first position, the fixing portion of the locking member and the fixing position on the connecting seat are mutually engaged to achieve the fixation of the two. Furthermore, the connecting seat and the helmet body are kept stably connected, and the elastic rope can be stably connected with the helmet body through the connecting seat without passing through the shell wall of the helmet body. When the locking member is switched to the second position, that is, the position where the fixing portion of the locking member and the fixing position on the connecting seat are mutually disengaged, the connecting seat can slide out of the installation groove on the helmet body upward along the second direction Y, which can facilitate the quick separation of the face shield body and the helmet body. Furthermore, the operator can directly replace and maintain the face shield body, the elastic rope and the helmet body, and quickly assemble them again, making the maintenance of the helmet convenient and fast.

[0012] In one embodiment, the locking member includes a control portion and a plugging board extending outward from the control portion; a support wall is horizontally disposed in the middle of the button slot; the plugging board penetrates through the support wall along a first direction; at least a part of the control portion covers the slot opening of the button slot; the elastic member is supported between the control portion and the support wall. In this way, the control portion can be pressed by the user's hand, thereby overcoming the acting force of the elastic member, so that the plugging board of the locking member reaches the second position, and the locking member is separated from the connecting seat, so that the connecting seat can slide upward along the second direction Y out of the helmet body, which can facilitate the quick separation of the visor body and the helmet body, so that the operator can quickly replace and maintain, and quickly assemble again, making the maintenance of the helmet convenient and fast; when the user releases the pressing, the elastic member can urge the plugging board of the locking member to return to the first position, so that the locking member and the connecting seat are locked with each other, so that the connecting seat and the helmet body maintain a stable connection, and 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, a notch is formed through the plugging board; the connecting seat penetrates through the notch; a fixing portion is formed by protruding into the notch on the side of the plugging board away from the control portion; the connecting seat includes a plurality of fixing positions for cooperating and locking with the fixing portion. In this way, by providing the fixing portion of the locking member and the fixing positions on the connecting seat, when the locking member is in the first position, the fixing portion and the fixing positions are mutually engaged to achieve the fixation of the two, ensuring the stable connection between the connecting seat and the helmet body; by providing a plurality of fixing positions spaced on the connecting seat, the connecting seat can be fixed at different positions of the installation slot; furthermore, the tightness of the elastic cord can be adjusted, facilitating the user to adjust the connection between the visor body and the helmet body, and avoiding the influence of the elastic cord being too tight or too loose on the relative adjustment of the visor body and the helmet body during use, improving the use experience.

[0014] In one embodiment, an elastic hook is formed by protruding outward from the side of the plugging board; a hook groove adapted to the elastic hook is formed on the side wall of the button slot.

[0015] In one embodiment, at least one positioning hole is formed on the helmet body, and the visor body includes fixing protrusions adapted to the positioning holes. In this way, the fixing protrusions on the visor body cooperate with the positioning holes at different positions, so that the visor body can be fixed at different positions on the outer peripheral surface of the helmet body, facilitating the user to adjust the position of the visor body according to needs.

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

[0017] In one embodiment, the connecting seat includes a connecting seat body and rollers. The rollers are rotatably arranged in the connecting seat body. Two through holes are formed on one side of the connecting seat body. The end of the elastic rope penetrates into one of the through holes, winds around the rollers and then passes out from the other through hole, and is connected to the mirror body. The connecting seat body can be locked with the locking assembly. In this way, the setting of the two through holes and the rollers facilitates the stable installation of the elastic rope and the connecting seat. And when the elastic rope deforms, the friction between the elastic rope and the connecting seat body can be effectively reduced through the rollers, which is convenient for the elastic rope to deform uniformly and improves the force on the connecting seat, being beneficial to extending the service life of the elastic rope and the connecting seat.

[0018] In one embodiment, the connecting seat body includes C-shaped grooves respectively formed on two side wall surfaces and a receiving groove located between the two side wall surfaces. The rollers include a wheel body and a rotating shaft fixedly arranged on the wheel body. Two ends of the rotating shaft are respectively embedded in the C-shaped grooves on the two side wall surfaces. The outer peripheral surface of the wheel body of the roller is concave to form an annular groove. The two through holes are located at the bottom side of the receiving groove and are respectively communicated with the receiving groove. In this way, the wheel body is erected in the receiving groove through the rotating shaft. The end of the elastic rope can penetrate into the upper through hole. The annular groove on the roller can provide positioning for the elastic rope to prevent the elastic rope from detaching from the roller during the rotation process. Finally, the end of the elastic rope passes out from the other through hole and is reconnected to the mirror body. The friction between the elastic rope and the connecting seat body can be effectively reduced through the rollers, which is convenient for the elastic rope to deform uniformly and improves the force on the connecting seat, being beneficial to extending the service life of the elastic rope and the connecting seat.

[0050] It should be noted that if an element is referred to as being "fixed to" or "disposed on" another element, it can be directly on the other element or there can also be an intermediate 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 intermediate element at the same time. If present, the terms "vertical", "horizontal", "up", "down", "left", "right" and similar expressions used in this application are only for illustrative purposes and do not represent the only implementation.

[0051] In the related art, some helmets connect the visor to the helmet body through a buckle and make the buckle fit tightly with the helmet body through an elastic band. For example, a helmet with a structure for fixing and adjusting the lens with an elastic band disclosed on the market includes a helmet body, glasses, a hollow tube provided on the inner wall of the helmet body, elastic bands respectively provided at both ends of the hollow tube, and buckles respectively provided on each elastic band; both ends of the hollow tube extend to the front of the helmet body, each elastic band is respectively clamped to both ends of the hollow tube, each buckle is located on both sides of the edge of the glasses, and each buckle is fixedly connected to the glasses.

[0052] Although the above structure can stably connect the visor to the helmet body and prevent the visor from freely moving relative to the helmet body, the elastic band is prone to damage after long-term use or under a large external force, thus affecting the normal use of the helmet. At this time, the user needs to reconnect a new elastic band to the buckle and thread it into the hollow tube, and the length of the elastic band cannot be too long, which is inconvenient for the assembly and repair of the helmet.

[0053] The embodiments of the present application provide a helmet that can be applied in the transportation field and the sports field; in particular, it can be applied in outdoor sports occasions such as cycling and skiing to provide protection functions for the human eyes and head.

[0054] Refer to 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 connecting seat 23.

[0055] Among them, the face shield main body 21 is movably arranged on the helmet main body 1. An elastic rope 22 is installed on the face shield main body 21 and at least partially extends outside the face shield main body 21 to form a mounting end. At least one connecting seat 23 is installed on the mounting end and is configured to be detachably fixed on the helmet main body 1.

[0056] Among them, the helmet main body 1 is used to wrap the human head, and it has a semi-closed accommodation cavity (not marked) inside; the helmet shell on the outside of the helmet main body 1 is usually made of hard plastic molding or fiberglass, and materials such as impact-resistant foam and elastic sponge can usually be arranged on the inner helmet lining of the helmet main body 1 to provide a comfortable use experience.

[0057] A face shield 2 is movably arranged at the front end of the helmet main body 1. The face shield 2 includes the above-mentioned face shield main body 21, elastic rope 22 and connecting seat 23. During use, the elastic rope 22 is sleeved on the helmet main body 1, and then the face shield main body 21 covers the user's eyes. The face shield main body 21 can be used to protect the human eyes. For example, it can prevent the cold wind from irritating the eyes; prevent the ultraviolet rays from burning the eyes, etc. When the face shield 2 is not needed, the face shield main body 21 can be moved away from the user's eyes, and under the restriction of the elastic rope 22, the face shield main body 21 is located at the top of the helmet main body 1 or other positions.

[0058] The face shield main body 21 is connected to the connecting seat 23 through the elastic rope 22. In this way, the face shield main body 21 and the helmet main body 1 can be stably connected, and the relative position and relative distance between the face shield main body 21 and the helmet main body 1 can be realized by adjusting the telescopic length of the elastic rope 22, avoiding the discomfort caused by the face shield main body 21 pressing on the human eyes or the face shield main body 21 being too loose and causing the face shield main body 21 to separate from the human eyes, improving the user's use experience;

[0059] In addition, the connecting seat 23 is detachably connected to the helmet main body 1, and the elastic rope 22 is fixed to the helmet main body 1 through the connecting seat 23, which can ensure that the elastic rope 22 does not need to pass through the shell wall of the helmet main body 1. On the one hand, it can simplify the structure of the helmet and facilitate the production and processing of the helmet; on the other hand, it can facilitate the quick separation of the face shield main body 21 from the helmet main body 1. When components such as the face shield main body 21, elastic rope 22 and helmet main body 1 need to be replaced and maintained, the connecting seat 23 is directly removed from the helmet main body 1, and the operator can directly replace and maintain the face shield main body 21, elastic rope 22 and helmet main body 1 and quickly assemble them again without passing the elastic rope 22 through the helmet main body 1, making the maintenance of the helmet convenient and fast.

[0060] Optionally, the helmet main body 1 can be streamlined, relatively light, and does not affect the field of vision, or it can also be spherical, specifically subject to the design.

[0061] Optionally, the face shield body 21 is integrally designed with a smooth arc and can be embedded into the helmet body 1.

[0062] Optionally, the elastic rope 22 can be made of rubber, nylon or an elastic composite material.

[0063] In some embodiments, referring to 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. The elastic rope 22 is threaded through the face shield body 21, and both ends of the elastic rope 22 are respectively connected to the two connecting seats 23 and then connected to the helmet body 1 through the connecting seats 23, so as to realize the stable connection between the face shield body 21 and the helmet body 1. In other embodiments, the helmet includes one connecting seat 23, and the connecting seat 23 is only provided on one side of the helmet body 1, specifically subject to the design.

[0064] It should be noted that the structure with connecting seats 23 provided on both sides of the helmet body 1 is usually symmetrical. Therefore, for the convenience of understanding, the structure of one side is described when describing the structure, and the structure of the other side will not be elaborated.

[0065] Different from the previous embodiment, in some other embodiments, the helmet may only include one connecting seat 23, and one side of the helmet body 1 is detachably connected to the elastic rope in other ways. For example, the elastic rope 22 is directly fixed to the outer shell of the helmet body 1 by bolts without the elastic rope 22 passing through the outer shell of the helmet body 1; the other side of the helmet body 1 can be provided with a connecting seat 23, and then the connecting seat 23 is used to keep the elastic rope 22 and the face shield body 21 in stable connection.

[0066] In some possible embodiments, referring to Figures 1 to 15 As shown, a notch adapted to the contour of the face shield body 21 is provided on the front side of the helmet body 1. An installation groove 12 is provided on one of the surface of the face shield body 21 and the connecting seat 23 facing the notch, and an installation protrusion adapted to the installation groove 12 is constructed on the other. The installation protrusion can be movably inserted into the installation groove. The helmet body 1 is also provided with a locking component, and the locking component is configured to selectively lock the installation protrusion in the installation groove 12 or release the installation protrusion so that the installation protrusion can be disengaged from the installation groove 12.

[0067] Specifically, when the installation protrusion is inserted into the installation groove 12, the positioning of the connecting seat 23 and the helmet body 1 can be achieved. The installation protrusion is selectively locked in the installation groove 12 by the locking component, so as to fix the connecting seat 23 and the helmet body 1. Then, through the connecting seat 23, it is connected to the helmet body 1, so as to realize the stable connection between the visor body 21 and the helmet body 1. By selectively loosening the installation protrusion by the locking component, the installation protrusion can be detached from the installation groove 12, so that the helmet body 1 and the connecting seat 23 can be quickly separated, and then the visor 2 and the helmet body 1 can be quickly separated, which is convenient for the user to quickly maintain the visor body 21, the elastic cord 22 and the helmet body 1.

[0068] It should be noted that the whole of the connecting seat 23 or at least part of the connecting seat 23 serves as the installation protrusion. In this way, a corresponding installation groove 12 is provided on the surface with the notch facing the visor body 21; similarly, the installation protrusion can be directly formed by protruding outward on the surface with the notch facing the visor body 21. In this case, the surface of the connecting seat 23 is recessed inward to form the installation groove 12.

[0069] In some possible embodiments, refer to Figures 1 to 15 As shown, a sunk fixing groove 11 is constructed on the edge of the notch; an installation protrusion or an installation groove 12 is provided on the groove wall of the fixing groove 11 facing the front side of the helmet body 1.

[0070] In this way, when the installation protrusion is provided on the groove wall of the fixing groove 11 facing the front side of the helmet body 1, the surface of the connecting seat 23 is recessed inward to form the installation groove 12; when the installation groove 12 is provided on the groove wall of the fixing groove 11 facing the front side of the helmet body 1, the whole of the connecting seat 23 or at least part of the connecting seat 23 serves as the installation protrusion.

[0071] It should be noted that whether the installation groove 12 is provided on the connecting seat 23 or the installation protrusion is provided on the connecting seat 23, the installation protrusion can be movably inserted into the installation groove 12; and the locking or separation described above is realized through the locking component.

[0072] For easy understanding, in the following embodiments, it is described with the installation protrusion located on the connecting seat 23 and the installation groove 12 provided on the surface with the notch facing the visor body 21.

[0073] In some possible embodiments, refer to Figures 1 to 5 As shown, an installation area is provided on the wall surface of at least one side of the left and right sides of the helmet body 1. The helmet includes a locking component. At least part of the locking component is located on the installation area and can selectively lock the connecting seat 23 to the installation area or loosen the connecting seat 23 to separate the connecting seat 23 from the installation area.

[0074] It should be noted that, in each embodiment of the present application, the helmet main body 1 is used to wrap the human head. According to the front, back, left and right sides of the human head, the helmet main body 1 also has a corresponding front end, rear end, left side and right side, wherein the left side and right side of the helmet main body 1 correspond to the human ear and the surrounding area, the front end of the helmet main body 1 corresponds to the human forehead and the surrounding area, and the rear end of the helmet main body 1 corresponds to the back of the human head and the surrounding area; therefore, in each embodiment of the present application, unless otherwise specified, each orientation of the helmet main body 1 is determined by the above-mentioned corresponding parts of the human body.

[0075] The locking assembly is at least partially located on the installation area, and the connecting seat 23 can be selectively locked in the installation area through the locking assembly, so as to facilitate the connection of the elastic rope 22 to the connecting seat 23, and then connected to the helmet body 1 through the connecting seat 23, so as to achieve a stable connection between the mirror body 21 and the helmet body 1; the connecting seat 23 can be selectively loosened through the locking assembly to separate the connecting seat 23 from the installation area, so that the helmet body 1 can be quickly separated from the connecting seat 23, and then the mirror 2 can be quickly separated from the helmet body 1, which is convenient for the user to quickly maintain the mirror body 21, the elastic rope 22 and the helmet body 1.

[0076] Optionally, the locking assembly may be a lock structure, a bead 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, the surface of the notch facing the mirror body 21 is inwardly recessed to form a mounting groove 12, and the connecting seat 23 is provided with a mounting convex portion; the wall surface of at least one of the left and right sides of the helmet body 1 is inwardly recessed to form a button groove 13, 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 installed 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 with the connecting seat 23; when the locking member 3 is in the second position, the locking member 3 is loosened from the connecting seat 23.

[0078] Specifically, a wall surface of at least one of the left and right sides of the helmet body 1 is recessed inwardly along a first direction X to form a button groove 13, and the first direction X is the left and right direction of the helmet body 1; the mounting groove 12 is connected to 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 convex portion of the connecting seat 23 can be locked in the mounting groove 12 of the helmet body 1 through the locking member 3, so as to fix the connecting seat 23 and the helmet body 1. Further, it is connected to the helmet body 1 through the connecting seat 23, thereby realizing the stable connection between the visor 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. In this way, when the locking member 3 is in the second position, the restriction of the locking member 3 on the connecting seat 23 can be released, so that the mounting convex portion of the connecting seat 23 can be disengaged from the mounting groove 12 of the helmet body 1, thereby enabling the helmet body 1 and the connecting seat 23 to be quickly separated. Further, the visor 2 and the helmet body 1 can be quickly separated, which is convenient for the user to quickly maintain the visor body 21, the elastic cord 22 and the helmet body 1.

[0081] Continue to refer to Figure 2 、 Figures 5 to 7 、and Figures 12 to 15 As shown, the locking assembly further includes an elastic member 4. The elastic member 4 is supported between the locking member 3 and the button groove 13, and can keep the locking member 3 in the first position.

[0082] Combined with Figure 6 and Figure 7 As shown in the orientation, 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 along the first direction X to the left, so as to facilitate the movable setting of the locking member 3 in the button groove 13.

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

[0084] Refer to Figures 12 to 15 As shown, and specifically combined with Figure 5 the orientation shown, Figure 5 the locking member 3 in

[0085] When it is necessary to disassemble the connecting seat 23 from the helmet main body 1, the locking member 3 can be switched to the second position, in combination with Figure 5 , and the second position is also the position where the locking member 3 in Figure 5 is moved to the bottom to the left along the first direction X, so that the fixing portion 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 out of the mounting groove 12 on the helmet main body 1 upward along the second direction Y, which can facilitate the quick separation of the visor main body 21 from the helmet main body 1. Furthermore, the operator can directly perform the replacement and maintenance of the visor main body 21, the elastic cord 22 and the helmet main body 1, and quickly assemble them again, making the maintenance of the helmet convenient and fast.

[0086] In some possible embodiments, referring to Figures 5 to 7 , and Figures 12 to 15 shown, the locking member 3 includes a control portion 31 and a plug-in board (not marked) extending outward from the control portion 31; a support wall 132 is horizontally arranged in the middle of the button groove 13; the plug-in board penetrates through the support wall 132 along the first direction X until it reaches the bottom of the button groove 13; at least a part of the control portion 31 covers the opening of the button groove 13; the elastic member 4 is supported between the control portion 31 and the support wall 132.

[0087] The control portion 31 can be pressed by the user's hand, thereby overcoming the acting force of the elastic member 4, so that the plug-in board of the locking member 3 reaches the second position, and the locking member 3 is disengaged from the connecting seat 23. Furthermore, the connecting seat 23 can slide out of the helmet main body 1 upward along the second direction Y, which can facilitate the quick separation of the visor main body 21 from the helmet main body 1. Furthermore, the operator can quickly perform replacement and maintenance and quickly assemble them again, making the maintenance of the helmet convenient and fast.

[0088] When the user releases the pressing, the elastic member 4 can urge the plug-in board of the locking member 3 to return to the first position, so that the locking member 3 is locked with the connecting seat 23. Furthermore, the connecting seat 23 and the helmet main body 1 are kept in a stable connection, and the elastic cord 22 can be stably connected to the helmet main body 1 through the connecting seat 23 without the elastic cord 22 passing through the shell wall of the helmet main body 1.

[0089] Among them, the support wall 132 is usually integrally provided with the button groove 13, and the support wall 132 has a crack or a missing hole (not marked) for the plug-in board to move through. Combining Figure 5 shown in the orientation, taking the support wall 132 as the boundary, the support wall 132 can divide the button groove 13 into a first space (not marked) on the left and a second space (not marked) on the right; the first space and the second space are communicated through the crack or the missing hole on the support wall 132.

[0090] The button slot 13 generally forms a slot opening on the inner side of the installation area of the helmet main body 1 facing inward; Figure 5 In the figure, the plug-in board sequentially passes through the slot opening of the button slot 13 to the left in the first direction X, passes through the first space, and penetrates the support wall 132 until it reaches the bottom of the second space of the button slot 13; the part of the plug-in board located in the second space can cooperate with the connecting seat 23, so as to selectively lock or release the connecting seat 23.

[0091] The control part 31 at least partially covers the slot opening of the button slot 13, so as to block the matching structure between the locking component and the helmet main body 1 and prevent sundries from falling in.

[0092] The elastic member 4 is supported between the control part 31 and the support wall 132, so that the locking member 3 can be kept in the first position.

[0093] Optionally, the control part 31 can be processed and formed by materials such as ABS plastic, polytetrafluoroethylene, aluminum alloy, copper alloy, etc.; the plug-in board can be processed and formed by materials such as ABS plastic, polytetrafluoroethylene, aluminum alloy, copper alloy, etc. The control part 31 and the plug-in board can adopt an integral structure; or they can be fixed into one body by welding after being processed separately.

[0094] In some possible embodiments, refer to Figures 1 to 15 As shown, the locking member 3 should be hidden and arranged in the button slot 13. That is, control the depth of the button slot 13, the thickness of the control part 31, and the length of the plug-in board; so that when the locking member 3 is in the second position, the control part 31 should be lower than the slot opening of the button slot 13; when the locking member 3 is in the first position, the control part 31 should be flush with or slightly recessed from the slot opening of the button slot 13; to ensure that the locking member 3 does not protrude from the inner wall of the helmet main body 1 in any position. In this way, on the one hand, during the use of the helmet, the hidden concave design can effectively prevent the locking member 3 from being accidentally triggered, thereby avoiding the accidental separation of the visor 2 and the helmet main body 1, which is beneficial to the stable installation of the connecting seat 23 and the helmet main body 1. On the other hand, when the user is using the helmet normally, it can avoid scratches or bruises caused by the protrusion of the control part 31 of the locking member 3, improving the use experience.

[0095] In some possible embodiments, refer to Figures 5 to 7 and Figures 12 to 15 As shown, a notch 32 is formed by hollowing out on the plug-in board, and the connecting seat 23 passes through the notch 32; a fixing part 33 protrudes into the notch 32 on the side of the plug-in board away from the control part 31, and the connecting seat 23 includes a plurality of fixing positions 234 for cooperating and locking with the fixing part 33 of the connecting seat 33.

[0096] In this way, 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 are mutually engaged to achieve the fixation of the two, ensuring a stable connection between the connecting seat 23 and the helmet body 1.

[0097] A plurality of fixing positions 234 are arranged at intervals on the side surface of the connecting seat 23 facing the fixing part 33. In this way, the connecting seat 23 can move in the mounting groove 12 so that the fixing part 33 of the locking member 3 cooperates with different fixing positions 234. Specifically, referring to Figure 5 As shown, when the locking member 3 is in the first position, the fixing part 33 of the locking member 3 and the first fixing position 234 on the connecting seat 23 are mutually engaged to achieve the fixation of the two; when the operator further pushes the connecting seat 23 to move downward along the second direction Y, the fixing part 33 of the locking member 3 and the second fixing position 234 on the connecting seat 23 are mutually engaged, and so on; in this way, the connecting seat 23 can be fixed at different positions in the mounting groove 12; furthermore, the tightness of the elastic cord 22 can be adjusted, facilitating the user to adjust the connection between the face shield body 21 and the helmet body 1, and avoiding the elastic cord 22 being too tight or too loose during use, which affects the relative adjustment of the face shield body 21 and the helmet body 1 by the user, and improving the use experience.

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

[0099] In some possible embodiments, referring to Figure 7 、 Figure 14 and Figure 15 As shown; an elastic hook 34 protrudes outward from the side of the plug-in board; a hook groove 131 adapted to the elastic hook 34 is formed on the side wall of the button groove 13.

[0100] In this way, the cooperation between the elastic hook 34 and the hook groove 131 can effectively prevent the locking member 3 from detaching from the helmet body 1, keeping the two as a whole. When the fixing part 33 of the plug-in board of the locking member 3 and the fixing position 234 on the connecting seat 23 are mutually engaged to achieve the fixation of the two, that is, the helmet body 1 and the connecting seat 23 are kept connected. By locking or releasing the connecting seat 23 with the locking member 3, the helmet body 1 and the connecting seat 23 can be quickly separated, and then the face shield 2 and the helmet body 1 can be quickly separated, facilitating the user to quickly maintain the helmet.

[0101] Combined with Figure 7In terms of orientation, the hook groove 131 is located at the bottom of the button groove 13; the vertical width of the hook groove 131 is greater than that of the remaining area of the button groove 13. During the process of inserting the plug-in board into the button groove 13, the elastic hook 34 can be compressed through its own inclined surface. When the elastic hook 34 reaches the bottom of the button groove 13, the elastic hook 34 resumes its shape and remains hooked to the hook groove 131.

[0102] The depth of the hook 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 arranged 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 hooking of the hook groove 131 and the elastic hook 34. When the locking member 3 moves to the second position under the action of an external force, the elastic hook 34 moves Figure 7 to the left side of the hook groove 131 as shown in the figure, but the elastic hook 34 is still within the range of the hook groove 131. At this time, the locking member 3 is disengaged from the connecting seat 23.

[0103] Optionally, a process groove (not marked) is also provided on the part of the plug-in board adjacent to the elastic hook 34 to facilitate the deformation of the elastic hook 34 and the insertion of the plug-in board of the locking member 3 into the button groove 13.

[0104] In some possible embodiments, refer to 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 marked) is formed on the front wall surface of the helmet body 1; the fixing groove 11 is arranged at the edge of the notch and extends along the notch to the installation areas on both sides. The mounting groove 12 is arranged on the side wall surface of the installation 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-back direction of the helmet body 1; the connecting seat 23 is movably arranged in the mounting groove 12 and can be locked with the locking member 3.

[0106] Among them, the helmet body 1 is used to wrap the human head. The notch on the front wall surface of the helmet body 1 should be able to fit the human eyes, that is, the shape profile is roughly the same as that of the eyes. The overall extension direction of the fixing groove 11 along the notch to both sides should match the outer contour of the face shield body 21, so that when the face shield body 21 is located at the front end of the helmet body 1, it can be embedded in the fixing groove 11 of the notch.

[0107] The connecting seat 23 can be inserted into the mounting groove 1 on the helmet main body 1 along the second direction Y and locked by the locking member 3 in the first position, so as to realize a stable connection between the connecting seat 23 and the helmet main body 1. The elastic cord 22 can maintain a stable connection with the helmet main body 1 through the connecting seat 23 without passing through the housing wall surface of the helmet main body 1.

[0108] When the locking member 3 switches to the second position, the fixing portion 33 of the locking member 3 is disengaged from the fixing position 234 on the connecting seat 23, so that the connecting seat 23 can slide upward along the second direction Y out of the mounting groove 12 on the helmet main body 1. In this way, it is convenient to quickly separate the visor main body 21 from the helmet main body 1, and then the operator can directly replace and maintain the visor main body 21, the elastic cord 22 and the helmet main body 1, and quickly assemble them again, making the maintenance of the helmet convenient and fast.

[0109] In some possible embodiments, refer to Figures 1 to 4 、 Figure 6 and Figure 8 As shown, at least one positioning hole 112 is formed on the helmet main body 1. The visor main body 21 includes fixing protrusions 212 adapted to the positioning holes 112.

[0110] Exemplarily, one of the positioning holes 112 can be arranged on the limiting wall 111 inside the fixing groove 11.

[0111] Exemplarily, one of the positioning holes 112 can be arranged on the wall surface of the top side of the helmet main body 1. The top side wall surface of the helmet main body 1 corresponds to the human head top and the nearby area.

[0112] According to needs, only one positioning hole 112 can be formed on the helmet main body 1, or multiple positioning holes 112 can be arranged in different areas according to needs.

[0113] The positioning hole 112 can be a groove structure, and the fixing protrusion 212 is a convex block structure cooperating with it. At least two or more positioning holes 112 are arranged on the helmet main body 1. All the positioning holes 112 are arranged at intervals in sequence from front to back on the outer side surface of the helmet main body 1 facing away from the accommodation cavity. The fixing protrusions 212 on the visor main body 21 cooperate with the positioning holes 112 at different positions, so that the visor main body 21 can be fixed at different positions on the outer peripheral surface of the helmet main body 1, facilitating the user to adjust the position of the visor main body 21 according to needs.

[0114] Specifically, in combination with Figures 1 to 3As shown, one of the positioning holes 112 is provided on the limiting wall 111 closer to the inner side of the fixing groove 11. When the user needs to use the face shield 2 of the helmet to protect the eyes, the face shield body 21 can be moved onto the fixing groove 11. At least part of the outer contour of the face shield body 21 can be fitted and positioned with the fixing groove 11, and the fixing protrusion 212 on the face shield body 21 is inserted into the positioning hole 112 on the limiting wall 111 closer to the inner side of the fixing groove 11. Then, the face shield body 21 is stably connected to the helmet body 1 through the elastic cord 22 and the connecting seat 23, so as to ensure that the face shield body 21 can stably cover the eyes of the human body and provide protection.

[0115] Combined Figure 1 、 Figure 2 and Figure 4 As shown, when the user does not need the face shield body 21 to cover the eyes of the human body, the face shield body 21 can be moved backward along the outer peripheral surface of the helmet body 1, and is fixed through the positioning hole 112 and the fixing protrusion 212 on the face shield body 21. Then, the face shield body 21 is stably connected to the helmet body 1 through the elastic cord 22 and the connecting seat 23, ensuring that the face shield body 21 can be stably connected to the helmet body 1.

[0116] Optionally, the fixing protrusion 212 is provided on the inner side surface of the face shield body 21 facing the accommodation cavity of the helmet body 1; referring to Figure 8 , the fixing protrusion 212 is located in the middle of the face shield body 21. Both sides of the face shield body 21 can be connected to the helmet body 1 through the elastic cord 22, so as to further ensure that the face shield body 21 can be stably connected to the helmet body 1.

[0117] In some possible embodiments, referring to 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 arranged in the connecting seat body 231, and two perforations 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 connecting seat body 231 can be a hollow square shell structure inside, and the front and rear sides of the connecting seat body 231 are penetrated. It is formed by connecting the top end surface (not marked), the bottom end surface (not marked) and two relatively arranged side wall surfaces (not marked). The connecting seat body 231 can be processed from materials such as ABS plastic, polytetrafluoroethylene, aluminum alloy, and copper alloy.

[0119] The connecting seat body 231 is inserted into the installation groove 12 movably along the second direction Y in the orientation of being penetrated front and rear, and a plurality of fixing positions 234 are arranged on the side wall surface of the connecting seat body 231, which is convenient for locking with the locking component at different positions.

[0120] When the elastic cord 22 is specifically connected to the connecting seat 23, the elastic cord 22 is usually threaded through the mask body 21. The end of the elastic cord 22 can penetrate into one of the through holes 235, wind around the roller 232 and pass out from the other through hole 235, and then reconnect to the mask body 21. In this way, the arrangement of the two through holes 235 and the roller 232 facilitates the stable installation of the elastic cord 22 and the connecting seat 23. And when the elastic cord 22 deforms, the friction between the elastic cord 22 and the connecting seat main body 231 can be effectively reduced through the roller 232, which is convenient for the elastic cord 22 to deform uniformly, improves the force on the connecting seat 23, and is beneficial to extending the service life of the elastic cord 22 and the connecting seat 23.

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

[0122] In this way, as combined with Figure 11 and Figure 12 shown, the wheel body is mounted in the receiving groove 2311 through the rotating shaft 2322. The end of the elastic cord 22 can penetrate into the upper through hole 235. The annular groove 2321 on the roller 232 can provide positioning for the elastic cord 22 to prevent the elastic cord 22 from detaching from the roller 232 during rotation. Finally, the end of the elastic cord 22 passes out from the other through hole 235 and reconnects to the mask body 21. The friction between the elastic cord 22 and the connecting seat main body 231 can be effectively reduced through the roller 232, which is convenient for the elastic cord 22 to deform uniformly, improves the force on the connecting seat 23, and is beneficial to extending the service life of the elastic cord 22 and the connecting seat 23.

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

[0124] Each fixing position 234 is a long-tooth-shaped structure. Each fixing position 234 includes a pressing wall 2342 and a guiding surface 2341; the guiding surface 2341 is inclined and arranged on the back side of the pressing wall 2342, and the pressing wall 2342 can be used to abut against the locking assembly.

[0125] Specifically, the fixing position 234 includes a guiding surface 2341 and an abutting wall 2342; one ends of the guiding surface 2341 and the abutting wall 2342 are connected, and the other ends of the guiding surface 2341 and the abutting wall 2342 respectively extend to the side wall surfaces of the connecting seat body 231 of the connecting seat 23, so that the fixing position 234 is formed into a strip-shaped rack structure. The guiding surface 2341 is inclined, and the abutting wall 2342 is perpendicular. The fixing portion 33 on the locking member 3 can also be provided with a tooth shape that can mesh with it.

[0126] Combined with Figure 5 , when the operator pushes the connecting seat 23 to move downward along the second direction Y, the guiding surface 2341 faces the fixing portion 33, and the guiding surface 2341 can abut against the fixing portion 33 of the locking member 3. Due to the action of the inclined surface, the guiding surface 2341 can convert the action along the second direction Y into an action of driving the locking member 3 to move to the second position, so that the connecting seat 23 can quickly reach the required depth along the second direction Y. After the operator stops pushing, the fixing portion 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 an external force pulls the connecting seat 23 to move upward along the second direction Y, the other side of the fixing position 234 is provided with an abutting wall 2342, and the abutting wall 2342 abuts against the fixing portion 33 of the locking member 3. Since the abutting wall 2342 is vertically arranged, the displacement of the locking member 3 can be effectively avoided, and further the disengagement of the connecting seat 23 from the mounting groove 12 can be avoided.

[0128] In this way, the setting of the guiding surface 2341 facilitates the quick installation and adjustment of the connecting seat 23 and the adjustment and installation of the plane mirror 2. The setting of the abutting wall 2342 prevents the relative movement between the locking member 3 and the fixing position 234 from occurring accidentally during use, and realizes the stable connection between the connecting seat 23 and the helmet assembly 1.

[0129] In some possible embodiments, refer to Figure 5 , Figure 8 , Figure 9 , and Figures 11 to 13 as shown; the connecting seat 23 includes a positioning groove 233 provided on the connecting seat body 231, and a positioning protrusion 211 adapted to the positioning groove 233 is formed on the plane mirror body 21.

[0130] Combined with Figure 11 , the bottom side of the receiving groove 2311 of the connecting seat body 231 has a bottom plate (not marked), the bottom plate is arranged on the front side of the connecting seat body 231 and is respectively connected to the two side wall surfaces, and a through hole 235 is formed on each of the upper side and the lower side of the bottom plate.

[0131] A positioning groove 233 is formed by inwards recessing from the bottom plate, and a positioning protrusion 211 adapted to the positioning groove 233 is formed on the face mirror main body 21. When the user needs to use the face mirror 2 of the helmet to protect the eyes, the face mirror main body 21 can be moved to the fixing groove 11. At least part of the outer contour of the face mirror main body 21 can be fitted and positioned with the fixing groove 11, and the fixing protrusion 212 on the face mirror main body 21 is embedded into the positioning hole 112 on the limiting wall 111 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 face mirror main body 21 is embedded into the positioning groove 233 on the connecting seat 23, playing a role of guiding and positioning, avoiding relative movement between the face mirror main body 21 and the helmet main body 1 during use, and finally enabling the face mirror main body 21 to stably cover the eyes of the human body to provide protection.

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

[0133] Both ends of the U-shaped connecting portion 221 are respectively connected to the face mirror main body 21, and the middle part of the U-shaped connecting portion 221 is wound around the roller 232 in the connecting seat 23. By setting the U-shaped connecting portion 221, it is beneficial for the face mirror main body 21 to be stressed at multiple points, thus facilitating the stable installation of the face mirror main body 21 and the helmet main body 1.

[0134] Specifically, the connecting portion 221 passes through the mounting hole 213 (mentioned below) on the face mirror main body 21, the connecting portion 221 enters the connecting seat main body 231 through the first through hole 235, and winds around the roller 232 and exits from the second through hole 235, and then is reconnected to the face mirror main body 21; the reconnection method can be fixing by tying a knot with a rope or fixing by a bolt.

[0135] The elastic rope 22 is connected to the face mirror main body 21 and the connecting seat 23 in a U-shaped structure; the connecting portion 221 can effectively cooperate with the two through holes 235 and the roller 232. When the elastic rope 22 deforms, the friction between the elastic rope 22 and the connecting seat main body 231 can be effectively reduced through the roller 232, facilitating the uniform deformation of the elastic rope 22 and improving the stress of the connecting seat 23, which is beneficial to extending the service life of the elastic rope 22 and the connecting seat 23.

[0136] In some possible embodiments, the helmet includes a connecting head 24; the connecting head 24 is detachably arranged on the face mirror main body 21. The end of the elastic rope 22 enters the connecting seat main body 231 through the first through hole 235, winds around the roller 232 and exits from the second through hole 235 and then is connected to the connecting head 24.

[0137] Specifically, the end of the elastic cord 22, that is, the connecting portion 221, passes through the mounting hole 213 on the face mirror main body 21. The connecting portion 221 enters the connecting seat main body 231 through the first through hole 235, winds around the roller 232, exits through the second through hole 235, and then reconnects with the connecting head 24 fixed to the face mirror main body 21, thereby ensuring that the end of the elastic cord 22 can stably connect the face mirror main body 21 and the connecting seat 23.

[0138] The connecting head 24 is detachably arranged on the face frame (mentioned below) of the face mirror main body 21; the connection method can be snap connection or bolt connection. The arrangement of the connecting head 24 facilitates the stable installation of the elastic cord 22 and the face mirror main body 21, facilitates the assembly of the helmet, and helps to prevent the accidental detachment of the elastic cord 22 and the face mirror main body 21 during use. When the connecting head 24 on the face mirror main body 21 is removed and the connection between the connecting head 24 and the connecting portion 221 is loosened, the connecting portion 221 can retract through the second through hole 235 and the roller 232 of the connecting seat 23 and exit through the first through hole 235. In this way, the face mirror main body 21 and the helmet main body 1 can be quickly disassembled without disassembling the connecting seat 23 and the helmet main body 1, and the maintenance is convenient and fast.

[0139] In some possible embodiments, refer to Figures 8 to 10 As shown, the face mirror main body 21 includes a connecting groove 215 and a clamping groove 216. The connecting head 24 includes a mounting portion 242 that cooperates with the connecting groove 215 and a clamping hook 244 that fits the clamping groove 216. A through limiting hole 241 is formed in the middle of the mounting portion 242, and the end of the elastic cord 22 is tied to the limiting hole 241.

[0140] The connecting head 24 includes a plate body for embedding into the connecting groove 215 and the clamping groove 216 and a mounting portion 242 protruding from the plate body. The clamping hook 244 is arranged at the distal end of the plate body away from the mounting portion 242 and protrudes from the plate surface.

[0141] The cooperation between the clamping hook 244 and the clamping groove 216 prevents the mounting portion 242 from detaching from the connecting groove 215, keeps the connecting head 24 and the face mirror main body 21 relatively fixed, and realizes the detachable connection between the face mirror main body 21 and the connecting head 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 detaching from the connecting head 24, enabling the stable connection between the elastic cord 22 and the face mirror main body 21. The arrangement of the connecting head 24 facilitates the stable installation of the elastic cord 22 and the face mirror main body 21, facilitates the assembly of the helmet, and helps to prevent the accidental detachment of the elastic cord 22 and the face mirror main body 21 during use, making it convenient for users.

[0142] Optionally, the connecting head 24 can be processed from materials such as ABS plastic, polytetrafluoroethylene, aluminum alloy, and copper alloy.

[0143] In some possible embodiments, referring to Figures 8 to 10 As shown, the mirror body 21 includes a receiving groove 210 for receiving the connector 24, and both the clamping groove 216 and the connecting groove 215 are provided at the bottom of the receiving groove 210. Among them, an L-shaped groove 218 is provided on the side of the connecting groove 215, and a convex portion 243 adapted to the L-shaped groove 218 protrudes from the side of the mounting portion 242.

[0144] Thus, the connector 24 is placed in the receiving groove 210, the mounting portion 242 is embedded downward into the connecting groove 215, and the convex portion 243 is embedded into the vertical section groove of the L-shaped groove 218. In a way of rotating a certain angle with the central axis of the mounting portion 242 as the rotation axis, the plate body of the connector 24 can be rotated into the clamping groove 216 and fixed by the clamping hook 244, and the convex portion 243 is embedded into the horizontal section groove of the L-shaped groove 218 to ensure 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 provided on the side of the connecting groove 215, which is convenient for the connector 24 to be fixedly connected to the receiving groove 210 from both sides to ensure uniform force.

[0146] In some possible embodiments, referring to Figures 8 to 10 As shown, the receiving groove 210 is formed with a guiding wall 217 on the adjacent groove walls of the clamping groove 216, and the clamping hook 244 can be guided by the guiding wall 217 and cooperate with the clamping groove 216 for fixation. During the rotation of the plate body of the connector 24 towards the clamping groove 216, the clamping hook 244 can be guided by the guiding wall 217 and cooperate with the clamping groove 216 for fixation, making the assembly and disassembly more convenient.

[0147] In some possible embodiments, referring to Figures 8 to 10 As shown, a clearance groove 219 is formed above the side wall of the receiving groove 210 corresponding to the clamping groove 216. After the plate body of the connector 24 rotates into place towards the clamping groove 216, the plate body of the connector 24 is fitted with the clamping groove 216, and the user can apply a force to the connector 24 through the clearance groove 219, so as to be able to drive it to rotate in the reverse direction, thereby driving the clamping hook 244 to disengage from the clamping groove 216.

[0148] In some possible embodiments, referring to Figures 8 to 10 As shown, the mirror body 21 includes a lens (not marked) and a frame (not marked) arranged around the lens;

[0149] The face shield main body 21 is formed with an installation channel (not marked); the installation channel extends along the outer contour shape of the face shield main body 21 to both sides respectively, and is formed with installation holes 213 communicating with the outside. The middle section of the elastic cord 22 is threaded through the installation channel, and the end of the elastic cord 22 passes out from the installation hole 213 and is connected to the helmet main body 1 through the connection seat 23.

[0150] Specifically, the inside of the face frame of the face shield main body 21 is hollow, so as to form an installation channel; the installation channel extends along the outer contour shape of the face frame to both sides respectively; it is convenient to arrange the elastic cord 22.

[0151] Specifically, refer to Figures 8 to 10 and in combination with Figure 1 、 Figure 2 、 Figures 11 to 13 As shown, the middle section of the elastic cord 22 is threaded through the installation channel. One end of the left side of the elastic cord 22 passes out from the installation hole 213 on the left side, and then is connected to the connection seat 23. That is, this part of the elastic cord 22, as the connection part 221, first penetrates into the through hole 235 on the upper side of the connection seat main body 231, winds around the roller 232, and the annular groove 2321 on the roller 232 can provide positioning for the elastic cord 22. The connection part 221 then passes out from another through hole 235 and is reconnected to the connection head 24 fixed on the face shield main body 21; in this way, it is beneficial for the face shield main body 21 to be stressed at multiple points, and finally ensures the stable connection between the face shield main body 21 and the helmet main body 1.

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

[0153] By arranging connection seats 23 on both sides of the face shield main body 21, the elastic cord 22 passes through the installation holes 213 and is respectively connected to the connection seats 23 on both sides, which is convenient for the two sides of the face shield main body 21 to be evenly stressed, so as to ensure the stable connection between the face shield main body 21 and the helmet main body 1. In addition, the middle section of the elastic cord 22 is received in the installation channel, which can effectively increase the deformation amount of the elastic cord 22 and facilitate the user to adjust the relative position of the face shield main body 21 and the helmet main body 1.

[0154] In some possible embodiments, refer to Figure 8 As shown, a plurality of hollow parts 214 communicating with the outside are formed on the side wall of the installation channel. The setting of the hollow parts 214 is convenient for the user to observe the elastic cord 22 in the installation channel and can facilitate the installation of the elastic cord 22.
