Description

Technical Field

[0001] This invention relates to the field of helmet technology, and in particular to a helmet with an adjustable hair channel. Background Technology

[0002] A helmet is a protective device used to protect the head from external forces. It is usually composed of core components such as a shell, a buffer layer, an inner liner, and straps. The shell provides rigid impact resistance, the buffer layer absorbs energy, and the inner liner provides a protective fit.

[0003] Most existing helmets have a closed structure, which is not suitable for female users with ponytails or buns, resulting in discomfort and poor stability.

[0004] Most cycling or sports helmets on the market are currently made of a single piece with a closed rear design. Some products have a circular or U-shaped opening at the rear to accommodate hair strands, but these openings are usually fixed and cannot be closed.

[0005] Although some helmets on the market have hair tie channels, allowing users to extend ponytails or buns from the openings, these channels are usually fixed openings that cannot be closed according to usage needs, affecting the overall protective performance of the helmet. Without hair ties, the openings may be too well ventilated or allow foreign objects to enter. Furthermore, if the hair ties are not securely fixed, they may wobble while riding. Summary of the Invention

[0006] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the invention.

[0007] In view of the problems existing in the above and / or existing adjustable hair channel helmets, the present invention is proposed.

[0008] Therefore, the problem to be solved by the present invention is how to solve the problem that the existing helmet hair tie channel is usually a fixed opening that cannot be closed according to the use needs, which affects the overall protective performance of the helmet; when there is no hair tie, the opening is too well ventilated or foreign objects can enter; and the hair tie is not firmly fixed and is easy to shake during riding.

[0009] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a helmet with an adjustable hair channel, comprising a helmet assembly including a helmet base, wherein a through groove is formed on the helmet base, a hair channel assembly is disposed in the through groove, including a fixing seat fixed in the through groove, a linkage member is rotatably connected in the fixing seat, a retracting member is disposed in the linkage member, the retracting member includes movable blades evenly arranged around the circumference, and a driving member is installed on the helmet base.

[0010] As a preferred embodiment of the helmet with adjustable hair channel described in this invention, the fixed base has a storage slot inside, and to provide space for the linkage mechanism to move, the outer ring of the fixed base has six empty slots to meet the movement space of the movable leaf, and all six empty slots are connected to the storage slot.

[0011] As a preferred embodiment of the helmet with adjustable hair channel according to the present invention, the linkage includes a rotating ring rotatably connected to the storage groove, and the outer ring of the rotating ring has an auxiliary groove for the movable blade to pass through.

[0012] In a preferred embodiment of the helmet with adjustable hair channel according to the present invention, the inner ring of the rotating ring is fixed with a first rack, and the outer ring of the rotating ring is fixed with a second rack.

[0013] As a preferred embodiment of the helmet with adjustable hair channel according to the present invention, the retractable component further includes a positioning shaft rotatably connected in the storage groove, and one end of the movable leaf is fixed on the positioning shaft.

[0014] As a preferred embodiment of the helmet with adjustable hair channel according to the present invention, wherein: one end of the positioning shaft is fixed with a first gear located in the storage groove, and the first gear meshes with a first rack.

[0015] As a preferred embodiment of the helmet with adjustable hair channel according to the present invention, wherein: the inner ring of the movable leaf is provided with an arc groove, the arc grooves on two adjacent movable leaves are staggered, and the two adjacent movable leaves are in sliding contact.

[0016] In a preferred embodiment of the adjustable hair channel helmet of the present invention, the driving component includes a second gear meshing with a second rack, an anti-slip block is fixed to the inner ring of the second gear, a damping seat is rotatably connected to one end of the anti-slip block, and the end of the damping seat away from the anti-slip block is fixed to the helmet base.

[0017] As a preferred embodiment of the helmet with adjustable hair channel according to the present invention, wherein: a protective shell for protecting the second gear is fixed on the outer ring of the fixing seat, and a groove is provided on one side of the protective shell.

[0018] As a preferred embodiment of the helmet with adjustable hair channel according to the present invention, a transparent goggle is rotatably connected to the front side of the helmet base.

[0019] The beneficial effects of this invention are as follows: by setting the hair passage component, multiple movable blades can be adjusted to a closed state when there is no need for hair to pass through, in order to block the passage and ensure the overall protection performance. When there is a need for hair to pass through, the movable blades can be actively opened, and then auxiliary clamping can be completed according to the thickness of the hair. This not only meets the need for hair to pass through, but also helps to improve the stability of hair fixation and effectively reduces the amplitude of random shaking of the hair.

[0026] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0027] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0028] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that is mutually exclusive with other embodiments.

[0029] Example 1, referring to Figure 1 and Figure 2 This is the first embodiment of the present invention. This embodiment provides a helmet with an adjustable hair channel, which includes a helmet assembly 1 and a hair channel assembly 2.

[0030] Specifically, the helmet assembly 1 includes a helmet base 11, on which a through groove 111 is provided.

[0031] Specifically, the through-type component 2 is set in the through-slot 111 and includes a fixed base 21 fixed in the through-slot 111. A linkage 22 is rotatably connected in the fixed base 21. A retractable component 23 is set in the linkage 22. The retractable component 23 includes movable blades 231 evenly arranged around the circumference. A drive component 24 is installed on the helmet base 11.

[0032] Example 2, refer to Figures 2-4 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0033] Specifically, the fixed base 21 has a storage slot 211 inside. To provide space for the linkage 22 to move, the fixed base 21 has six empty slots 212 on its outer ring to provide space for the moving leaf 231 to move. All six empty slots 212 are connected to the storage slot 211.

[0034] Specifically, the linkage 22 includes a rotating ring 221 rotatably connected to the storage groove 211, and the outer ring of the rotating ring 221 has an auxiliary groove 2211 through which the movable blade 231 passes.

[0035] The auxiliary groove 2211 is larger than the movable blade 231, and is used to ensure that the movable blade 231 can still rotate through the space while the rotating ring 221 is rotating.

[0036] Specifically, the inner ring of the rotating ring 221 is fixed with a first rack 222, and the outer ring of the rotating ring 221 is fixed with a second rack 223.

[0037] Specifically, the retractable component 23 also includes a positioning shaft 232 rotatably connected to the storage groove 211, and one end of the movable leaf 231 is fixed to the positioning shaft 232.

[0038] Specifically, a first gear 233 is fixed at one end of the positioning shaft 232 and located in the storage groove 211. The first gear 233 meshes with the first rack 222.

[0039] Specifically, the inner ring of the movable blade 231 is provided with an arc groove 2311, and the arc grooves 2311 on two adjacent movable blades 231 are staggered, and the two adjacent movable blades 231 slide in contact.

[0040] Specifically, the drive component 24 includes a second gear 241 that meshes with the second rack 223. An anti-slip block 242 is fixed to the inner ring of the second gear 241. A damping seat 244 is rotatably connected to one end of the anti-slip block 242. The end of the damping seat 244 away from the anti-slip block 242 is fixed to the helmet base 11.

[0041] The damping seat 244 effectively increases the friction force that the anti-slip block 242 needs to overcome to rotate, thereby preventing the anti-slip block 242 from rotating arbitrarily without the action of a direct rotational force.

[0042] Specifically, a protective shell 243 for protecting the second gear 241 is fixed on the outer ring of the fixed base 21, and a groove 2431 is provided on one side of the protective shell 243.

[0043] By setting up the protective shell 243, when the wearer blindly twists the anti-slip block 242, the hand can be prevented from coming into contact with the second gear 241, thus avoiding hand scratches and failure of the second gear 241 to mesh with the second rack 223, which is more in line with actual use needs.

[0044] Specifically, a transparent goggle 12 is rotatably connected to the front of the helmet base 11. When rotated downwards to close, it blocks dust, sand, insects, foreign objects, and direct wind and rain, preventing eye interference or damage. The working principle of this part is existing technology and can be clearly understood by those skilled in the art, so it will not be described in detail here.

[0045] In practical applications, the helmet base 11 should be equipped with a safety harness structure that conforms to industrial standards, which is not shown in the figure. The working principle of this part is all existing technology, which can be clearly understood by those skilled in the art, and will not be described in detail here.

[0046] The movable leaf 231 includes an integrated block and a rubber strip fixed to the side of the integrated block. The rubber strip is located at the arc groove 2311. That is, when multiple movable leaves 231 are assembled, multiple rubber strips are squeezed against each other to form a seal and prevent airflow from entering the helmet assembly 1 during wearing.

[0047] The rubber strip also provides elastic protection when the wearer's hand passes through the slot 111 to hold the hair bundle, preventing the hard design from scratching the wearer.

[0048] Meanwhile, the presence of the rubber strip increases the friction between the active blade 231 and the hair bundle when positioning the hair bundle, preventing the hair bundle from swaying randomly, and also allows for elastic contact with the hair bundle, avoiding damage from hard contact with the hair strands, which is more in line with actual wearing needs.

[0049] The integrated block consists of a hard block, a buffer pad, and an elastic liner from the outside to the inside, similar to the basic components of a helmet. The working principle of this part is existing technology and can be clearly understood by those skilled in the art, so it will not be described in detail here.

[0050] When the active leaf 231 is closed, the integrated block plays a protective role, and the protective performance is greatly improved compared to the traditional helmet hair channel opening fixed design.

[0051] The rotating ring 221 and the storage groove 211, and the movable blade 231 and the auxiliary groove 2211 are all sealed.

[0052] The first gear 233, the first rack 222, the second rack 223, and the second gear 241 are all made of UV-resistant modified nylon. With the addition of ultraviolet absorbers and light stabilizers, they have excellent self-lubricating and wear-resistant properties, making them suitable for the low-friction requirements of meshing transmissions. They are also highly impact-resistant and can adapt to thermal expansion and contraction caused by temperature differences between day and night outdoors. They are resistant to moisture, weak acids and alkalis, and are not easily corroded by rain or dew.

[0053] When in use and worn naturally, the movable leaf 231 is in a closed state, as shown in the attached diagram in the instruction manual. Figure 1 As shown, the through groove 111 can be sealed to ensure overall protection performance.

[0054] When there is a need for hair strands to pass through, the drive component 24 is actively driven to rotate, which drives the second gear 241 to rotate. Under the meshing transmission of the second rack 223, the rotating ring 221 rotates circumferentially in the receiving groove 211. Then, the first rack 222 and the first gear 233 cooperate to make multiple movable blades 231 rotate and open synchronously, gradually passing through and exposing the through groove 111.

[0055] At this time, the wearer can put their hand through the slot 111, hold the hair bundle, and pull the hair bundle out from the slot 111. Then, reverse the second gear 241 so that multiple movable leaves 231 gradually retract and close. The movable leaves 231 can be used to assist in clamping the hair bundle and help improve the stability of the hair bundle.

[0056] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
