Description

Technical Field

[0001] This utility model relates to the field of head protection equipment technology, specifically to an ear protector and helmet connection structure, and a helmet. Background Technology

[0002] A helmet is a piece of equipment used to cover and protect the human head. It reduces the risk of head injury by absorbing impact energy through a shell and a cushioning layer. Helmets are widely used in transportation, sports, and industrial settings. Different applications have led to diverse functional requirements for helmets. For example, in addition to cushioning impacts, ski helmets usually also need to provide warmth. Therefore, ski helmets are typically equipped with fabric ear protectors to provide extra protection for the wearer's ears in extremely cold conditions.

[0003] In existing ski helmet products, the ear protectors are detachably connected to the helmet body, allowing users to choose ear protectors of suitable material, shape, and thickness according to their needs. Currently, the methods for detaching and assembling the ear protector components vary among different products.

[0004] For example, some ear protectors have plastic inserts that are inserted between the shell and the EPS foam material during installation to restrict lateral movement of the ear protector. The inserts also have snaps that connect to the snaps fixed to the helmet body to prevent the ear protector from detaching. This method of connecting ear protectors to the helmet is complex, requiring inserts, rivets, male and female snaps, and other components; it also requires simultaneous alignment of multiple points and two snap fastenings; furthermore, rivets need to be installed on the outside of the shell, affecting the helmet's appearance.

[0005] For example, some ski helmets have embedded "female buckle" plastic parts in the EPS foam material for inserting inserts, while the ear flaps have plastic inserts with an inverted buckle structure. When the insert is inserted into the "female buckle," the inverted buckle structure provides a fixing effect. When installing this type of ear flap, there is no obvious feedback after the insert is inserted into the helmet, and the operator cannot feel whether it is installed correctly; they can only check if it is installed by gently pulling. Furthermore, the inverted buckle structure will wear down after repeated disassembly and assembly, resulting in a short lifespan and eventual loss of stability with long-term use. In addition, disassembly and assembly can only be done by "pulling" it out, which is not a pleasant experience for the wearer.

[0006] For example, patent CN220694495U discloses a ski helmet with detachable ear pads. This ski helmet includes an inner liner and an outer shell covering the entire body. The inner liner has mounting holes on its two bottom outer walls. A mounting plate, adapted to fit the mounting hole, is movably installed inside each hole. A buckle is provided on the mounting plate, and an elastic pad is placed on the ear pad. The ear pad is installed on the mounting plate by inserting the rubber pad into the buckle and closing it. The ear pad is then installed on the helmet by inserting the mounting plate into the inner liner. However, removing the ear pads requires first removing the entire mounting plate and then operating the buckle, which is cumbersome. Furthermore, the connection between the mounting plate and the inner liner may wear and loosen after repeated use, affecting the overall connection stability. Utility Model Content

[0007] To address the shortcomings of existing technologies, this utility model discloses an ear protector and helmet connection structure and a helmet, which solves the technical problems of existing ear protector and helmet connection structures involving many components, complex operation, low stability, and poor user experience.

[0008] To achieve the above technical objectives, this utility model proposes an ear protector and helmet connection structure, which includes a male buckle and a female buckle; wherein:

[0009] The male buckle has a plate-shaped insertion part, the front end of the insertion part has a guide slope, and the middle part forms an elastically deformable limiting pressure plate; the limiting pressure plate is stepped, the upper and lower planes are connected by a slope or vertical surface, and the lower plane is close to the front end of the insertion part and has a locking protrusion, and the upper plane forms a pressing surface; the rear end of the insertion part is used to connect the ear protector.

[0010] The female buckle is provided with an insertion frame that is adapted to the thickness of the male buckle insertion part. The top surface of the insertion frame is provided with a locking part that engages with the locking protrusion, and the end of its top surface is provided with an operation window for the pressing surface to be exposed.

[0011] In the above technical solution, the female buckle is used to be set in the buffer layer of the helmet. When the insertion part is inserted into the insertion frame, the engaging protrusion engages with the engaging part to realize the connection between the ear warmer and the helmet. Pressing the pressing surface can separate the engaging protrusion from the engaging part, thereby realizing the separation between the ear warmer and the helmet.

[0012] Furthermore, the bottom surface of the insertion frame is provided with a first through hole that matches the width of the insertion part.

[0013] Furthermore, the surface of the insertion frame is connected to the cover plate via a hinge, the hinge being configured such that the cover plate folds and covers the first through hole.

[0014] Furthermore, the bottom surfaces of the cover plate and the insertion frame are provided with a plurality of positioning parts that are mutually concave and convex.

[0015] Furthermore, the side of the female buckle is connected to an anchoring component.

[0016] Furthermore, the edge of the insertion frame is flush with or below the surface of the helmet's buffer layer.

[0017] Furthermore, a connecting piece is provided at the rear end of the insertion part, and the male buckle is connected to the ear protector through the connecting piece.

[0018] Furthermore, the connecting piece is provided with several third through holes.

[0019] Furthermore, the front end of the insertion part is provided with a second through hole and / or the end of the guide slope is provided with a positioning protrusion.

[0020] Furthermore, the male and female buckles are both injection-molded plastic parts.

[0021] On the other hand, this utility model proposes a helmet that includes the aforementioned ear protector and helmet connection structure. This ear protector and helmet connection structure can be used in military helmets, industrial and sports helmets, flight helmets, and other fields requiring a detachable connection between the ear protector and the helmet. In different usage scenarios, appropriate materials, shapes, and thicknesses of the ear protectors can be selected as needed, promoting the helmet's ability to simultaneously achieve functions such as noise reduction, communication, warmth, or impact protection.

[0022] Optionally, the helmet is a ski helmet. Different ski helmet wearers can choose appropriate ear protectors as needed and install them on the ski helmet through the connection structure of this utility model.

[0023] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0024] This utility model's connection structure involves only a male and female buckle, featuring a simple structure and efficient operation. In use, the male buckle connects to the ear protector assembly, while the female buckle is fixed within the helmet's buffer layer. By inserting the male buckle's insertion part into the female buckle's insertion frame, the engaging protrusion deforms and engages with the engaging part, connecting the male and female buckles and thus attaching the ear protector to the helmet. During this process, the engaging protrusion rebounds, producing a sound to indicate proper installation to the user. This avoids repeated operations due to uncertainty about installation, reduces structural wear, improves stability and lifespan, and comprehensively enhances the user experience. When the ear protector needs to be removed, simply press the pressing surface exposed from the operation window to disengage the engaging protrusion from the engaging part, separating the male and female buckles and completing the ear protector removal. The overall operation is convenient and quick, effectively avoiding structural wear caused by forceful insertion and removal, while significantly reducing the external force required for disassembly, further improving the product's user experience and durability.

[0036] Example 1

[0037] An ear protector connection structure to a helmet, such as Figure 1 As shown, the structure includes a male buckle 1 and a female buckle 2; wherein:

[0038] The male buckle 1 has a plate-shaped insertion part 11. The front end of the insertion part 11 has a guide slope 12, and the middle part forms a limit pressure plate that can be elastically deformed. The limit pressure plate is stepped, with the upper and lower planes connected by a slope or vertical surface. The lower plane is close to the front end of the insertion part 11 and has a locking protrusion 131. The upper plane forms a pressing surface 132. The rear end of the insertion part 11 is used to connect the ear protector.

[0039] The female buckle 2 is provided with an insertion frame 21 that is adapted to the thickness of the insertion part 11 of the male buckle 1. The top surface of the insertion frame 21 is provided with a locking part 22 that engages with the locking protrusion 131, and the end of its top surface is provided with an operation window 23 for the pressing surface 132 to be exposed.

[0040] In this embodiment, the female buckle 2 is used to be set inside the buffer layer of the helmet. When the insertion part 11 is inserted into the insertion frame 21, the engaging protrusion 131 engages with the engaging part 22 to achieve the connection between the ear protector and the helmet. Applying pressure to the pressing surface 132 can separate the engaging protrusion 131 from the engaging part 22, thereby achieving the separation between the ear protector and the helmet.

[0041] When installing ear protectors using the connection structure of this embodiment, simply insert the insertion part 11 of the male buckle 1 into the insertion frame 21 of the female buckle 2 until the engaging protrusion 131 engages with the engaging part 22 and a popping sound is heard, indicating that the male buckle 1 and female buckle 2 have engaged. The other end of the insertion part 11 of the male buckle 1 is used to connect the ear protector, while the female buckle 2 is installed in the helmet's buffer layer during use. Therefore, the ear protector can be installed on the helmet using the connection structure of this embodiment. When removing ear protectors using the connection structure of this embodiment, simply press the pressing surface 132 exposed from the operating window 23. The elastic pressing surface 132 will cause the engaging protrusion 131 on the limiting pressure plate to actively disengage from the engaging part 22 of the female buckle 2, thus separating the male buckle 1 and female buckle 2, and removing the ear protector connected to the male buckle 1 from the helmet. The overall ear protector installation and removal operation is convenient and labor-saving, providing a good user experience. It can be used to connect ear protectors of any shape, size, thickness, and material to helmets, making it widely applicable.

[0042] Understandably, the shape of the insertion frame 21 is adapted to the insertion part 11 of the male buckle 1. Understandably, the operation window 23 is provided on the insertion frame 21 at the end near the input of the insertion part 11, so that the pressing surface 132 is exposed after the male buckle is connected to the female buckle, providing a pressing surface for subsequent removal of the ear protector.

[0043] Furthermore, the front end of the insertion part 11 refers to the end of the insertion part 11 that is close to the female buckle 2 when the male buckle 1 is connected to the female buckle 2, and the rear end of the insertion part 11 refers to the end of the insertion part 11 that is far away from the female buckle 2 when the male buckle 1 is connected to the female buckle 2.

[0044] It should be noted that the shape of the engaging protrusion 131 is not limited in this invention. It can be a regular rectangle, trapezoid, circle or other irregular shape. Correspondingly, the shape of the engaging part 22 is adapted to the shape of the engaging protrusion 131 to achieve engagement.

[0045] It should be noted that this embodiment does not limit the connection method between the ear protector and the insertion part 11. The ear protector can be connected to the male buckle 1 by means of bonding, weaving, sewing, or other methods. Any connection method that satisfies the purpose of connecting the male buckle 1 to the helmet will achieve the purpose of connecting the ear protector to the helmet. In addition, this embodiment does not limit the specific structure of the ear protector. Those skilled in the art can set ear protectors of appropriate materials, shapes, thicknesses, and sizes as needed and connect them to the male buckle 1, so as to be suitable for the helmet and ear protector usage needs of different users and scenarios, and to facilitate the installation and removal of the ear protectors.

[0046] Example 2

[0047] Based on the ear protector and helmet connection structure shown in Embodiment 1, combined with Figure 2 and Figure 3 In this embodiment, the structure of the female buckle 2 has been optimized.

[0048] Optionally, the bottom surface of the insertion frame 21 is provided with a first through hole 24 that matches the width of the insertion part 11. The first through hole 24 can provide clearance space for the engaging protrusion 131. When the male buckle 1 is inserted, the engaging protrusion 131 is first pressed down. The engaging protrusion 131 needs to move downward a certain distance. By setting the first through hole 24, a clearance cavity can be formed to avoid interference between the protrusion and the bottom wall of the female buckle 2, so that the engagement is in place and a clear "click" feedback is emitted.

[0049] Optionally, the surface of the female buckle 2 is connected to the cover plate 252 via a hinge 251. The hinge 251 is configured such that the cover plate 252 folds and covers the first through hole 24. In actual use, the female buckle 2 is fixed in the buffer layer of the helmet. During the preparation of the buffer layer in the helmet manufacturing process, taking EPS buffer layer foaming as an example, the female buckle 2 will be pre-set in the position of the buffer layer. In order to prevent EPS material from entering the inner cavity of the insertion frame 21 through the bottom surface of the insertion frame 21 and causing blockage during the foaming process, a foldable cover plate 252 is provided in this embodiment. After the cover plate 252 is folded, it covers the first through hole 24 on the bottom surface of the female buckle 2, thereby protecting the inner cavity of the insertion frame 21 of the female buckle 2 during the EPS foaming process.

[0050] It should be noted that this embodiment does not limit the specific structure of the hinge portion 251. Figure 2 and Figure 3 An example of the hinge 251 is shown. Those skilled in the art can choose a structure that allows the cover plate 252 to be connected to the female opening and folded to the bottom surface of the insertion frame 21, as needed. It should be noted that this embodiment does not limit the folding angle of the cover plate 252. Figure 2 and Figure 3 An example is shown where the cover plate 252 extends parallel to the insertion frame 21, so that the female buckle 2 can be integrally formed.

[0051] Further optionally, the bottom surfaces of the cover plate 252 and the insertion frame 21 are provided with a plurality of mutually cooperating positioning parts to define the position between the cover plate 252 and the mating parts. Optionally, as... Figure 3 As shown, the positioning part includes a positioning hole 271 and a positioning protrusion 272 that can cooperate with it; optionally, the positioning part includes a concave positioning unit and a convex positioning unit with complementary shape, thereby realizing the positional limitation between the cover plate 252 and the mating part through concave-convex fitting.

[0052] Example 3

[0053] Based on the ear protector and helmet connection structure shown in Embodiment 1, combined with Figure 2 and Figure 3In this embodiment, the side of the female buckle 2 is connected to the anchoring component 26, which extends from the side of the female buckle into the buffer layer of the helmet. Optionally, the surface of the anchoring part has a friction-increasing structure for embedding the buffer material and forming pull-out resistance, so as to achieve a firm connection between the female buckle 2 and the buffer layer material.

[0054] It should be noted that the present invention does not limit the specific structure of the anchoring component 26, and those skilled in the art can choose one or more combinations of structures as needed.

[0055] Optionally, the edge of the insert frame 21 may be flush with or below the surface of the helmet's buffer layer, which helps maintain the overall aesthetic appearance of the helmet and improves its overall protective performance. The edge of the insert frame 21 may be flush with the surface of the helmet and the buffer layer, with mounting holes provided in the helmet's buffer layer to expose the pressing surface 132 of the male buckle 1. Further optionally, the edge of the insert frame 21 may have a structure to increase friction, such as several raised grooves 211.

[0056] Example 4

[0057] Based on the ear protector and helmet connection structure shown in Embodiment 1, combined with Figure 4 In this embodiment, the structure of male buckle 1 has been optimized.

[0058] Optionally, the rear end of the insertion part 11 is provided with a connecting piece 14, through which the male buckle 1 is connected to the earmuff. The connecting piece 14 makes the connection between the earmuff and the male buckle 1 more secure, and also provides a shaping skeleton for the soft earmuff to prevent it from collapsing after long-term wear, maintain a snug fit, and comprehensively improve the durability of the earmuff.

[0059] Further optionally, as shown in the figure, the connecting piece 14 is provided with a plurality of third through holes 141, which can be used as sound transmission holes to connect the outside world with the ear canal, so as to realize the introduction of ambient sound and maintain lateral protection.

[0060] Optionally, the pressing surface 132 is provided with friction-enhancing textures to improve operability.

[0061] Optionally, the front end of the insertion part 11 is provided with a second through hole 121, which can buffer the insertion operation of the insertion part 11. And / or the end of the guide slope 12 is provided with a buffer protrusion 122, which can play a positioning and buffering function, improving the user experience of the ear protector and helmet connection structure of this embodiment.

[0062] Example 5

[0063] Based on the ear protector and helmet connection structure shown in Embodiment 1, the male buckle 1 and female buckle 2 in this embodiment are injection-molded plastic parts with high dimensional accuracy and good consistency, which can be mass-produced. Moreover, the ear protector and helmet connection structure in this embodiment does not require the setting of metal springs, inserts or rubber parts, and the overall structure is simple and low in cost. In addition, the one-piece molded plastic parts do not crack or rust at low temperatures, are waterproof and dustproof, which improves the reliability and service life of the connection structure of this utility model in skiing environment.

[0064] It should be noted that the above description is a further detailed explanation of the present invention in conjunction with specific embodiments, and should not be construed as limiting the specific implementation of the present invention to these descriptions; the dimensional data in this embodiment do not limit the technical solution, but merely illustrate one specific working condition. For those skilled in the art to which this invention pertains, several simple improvements and modifications can be made without departing from the concept of the present invention, and all such improvements and modifications should be considered to fall within the scope of protection of the present invention.
