Abstract
Description
Technical Field

[0002] As a crucial piece of equipment for protecting cyclists' heads, the performance and comfort of helmets have received considerable attention. With increasing emphasis on cycling safety and the growing popularity of cycling activities, the limitations of traditional helmets are becoming increasingly apparent.
[0003] Traditional helmets with adjustable internal frames tend to position the head too far back when worn too tightly, leading to uneven pressure on the head. The back of the head experiences significant pressure, while the forehead area is relatively loose. This not only affects comfort but also reduces the helmet's overall protection against impacts. This discomfort accumulates during long rides, diminishing the riding experience. This project aims to develop a helmet with adjustable centering and impact-absorbing features to address these issues. Utility Model Content

Furthermore, the technical terms used in this specification are merely for clarity and not intended to limit the scope of the invention.

[0034] The specific embodiments of this application will now be described in detail with reference to the accompanying drawings. Numerous specific details are set forth in the following description to provide a thorough understanding of this application.
[0035] In one embodiment of this application, such as Figures 1-6 As shown, a helmet with centering adjustment and impact force dissipation functions is provided, comprising:
[0036] Helmet 1;
[0037] A semi-circular soft rubber frame 4 is fixed to the helmet body 1 at the middle and its two ends are movably connected to the helmet body 1 through the middle suspension frame 7 so that the two ends of the soft rubber frame 4 can swing and stretch.
[0038] Adjuster 2 is located inside the helmet body 1. Its two ends are connected to the inner soft rubber frame 4 by wires 10. The wires 10 are wrapped around the inner soft rubber frame 4 to allow the adjuster 2 to pull the wires 10 to shrink the inner soft rubber frame 4 as a whole.
[0039] The inner liner 3 is connected to the inner liner soft rubber frame 4 at multiple points through multiple front suspension brackets 6 and multiple middle suspension brackets 7, and the inner liner 3 is movably connected to the helmet body 1 through multiple rear suspension strips 11.
[0040] It should be noted that this structural design allows the helmet to better fit the heads of different wearers. The shrinkage of the inner soft rubber frame 4 can be adjusted by the swingable stretching of both ends of the inner soft rubber frame 4 and the pulling of the silk thread 10 by the adjuster 2. Combined with the flexible multi-point connection between the inner liner 3, the inner soft rubber frame 4 and the helmet body 1, it not only achieves flexible adjustment of the internal space of the helmet, improving wearing comfort and stability, but also, because the inner liner 3 can move back and forth and left and right, when the helmet is subjected to external impact, the movement displacement of the helmet can achieve the effect of dissipating force and reducing head injury.
[0041] Specifically, the swinging stretch of the inner soft rubber frame 4 allows the helmet cavity to adapt to the shape of the head. The wrapping traction of the silk thread 10 causes the inner liner 3 to apply pressure to the forehead, temples, and back of the head simultaneously. The inner liner 3 is movably connected to the helmet body 1 through multiple rear suspension strips 11, forming a torque balance. When the head moves forward, it triggers a reverse pull. When the adjuster 2 is rotated, the silk thread 10 contracts and drives the two ends of the inner soft rubber frame 4 to move closer to the center. At this time, the front suspension frame 6 of the inner liner 3 is pressed forward and pushes the head forward, while the rear suspension strip 11 is pulled backward and pulls the head back. The combined force of the two makes the inner liner system form a "push forward and pull back" clamping effect, forcing the head to stay at the geometric center of the helmet body 1.
[0042] Traditional helmets often have a fixed internal structure. The inner soft rubber frame 4 is made of soft rubber, and the inner liner 3 and the adjuster 2 are fixedly connected at three points. When the inner soft rubber frame 4 shrinks as a whole, the inner soft rubber frame 4 and the inner liner 3 will actually passively move closer to the adjuster 2. As a result, after the helmet is worn, the head is positioned as far back as possible inside the helmet body 1, causing uneven force on the head, strong pressure on the back of the head and looseness in the forehead.
[0043] In one embodiment of this application, a vertical extension is provided in the middle of the inner soft rubber frame 4, and the vertical extension is fixedly connected to the helmet body 1 by a front positioning pin 5.
[0044] The middle part of the central suspension frame 7 is fixedly connected to the helmet body 1 by the central positioning pin 8, and the two ends of the central suspension frame 7 are respectively connected to the inner lining soft rubber frame 4 and the inner lining piece 3.
[0045] The rear suspension strip 11 on one side of the inner liner 3 is connected to the helmet body 1 via the first rear positioning pin 12.
[0046] It should be noted that the three-level anchoring of the inner soft rubber frame 4 is achieved through the front positioning pin 5 and the middle positioning pin 8, and a linkage relationship with the inner liner 3 is established. Traditional helmet liners are only fixed by edge rivets, which are prone to tearing of the anchoring points due to long-term use. This structure forms a triangular support area through the front positioning pin 5, the middle positioning pin 8 and the first rear positioning pin 12, which disperses the tension to the rigid area of the helmet body 1. The middle suspension frame 7 serves as a floating fulcrum, allowing the inner soft rubber frame 4 to swing within a small range.
[0047] When the head moves from side to side, the inner soft rubber frame 4 deflects around the central positioning pin 8 as the axis, the front positioning pin 5 bears the shear force, and the rear suspension strip 11 absorbs the impact energy through elastic deformation.
[0048] In one embodiment of this application, the inner liner 3 is detachably connected to the front suspension bracket 6 and the middle suspension bracket 7, and the rear suspension strip 11 on one side of the inner liner 3 is detachably connected to the first rear positioning pin 12.
[0049] It should be noted that the inner liner 3 is detachably connected to the front suspension bracket 6, the middle suspension bracket 7, and the rear suspension strip 11, which allows users with different head circumferences to quickly replace the inner liner 3.
[0050] In one embodiment of this application, the inner liner 3 is connected to the front suspension bracket 6 and the middle suspension bracket 7 by snap-fit.
[0051] It should be noted that the inner liner 3 is connected to the front suspension frame 6 and the middle suspension frame 7 by snap-fit, which ensures a stable connection between the inner liner 3 and the front suspension frame 6 and the middle suspension frame 7, while also enabling quick disassembly and installation, further enhancing the maintainability of the helmet.
[0052] In one embodiment of this application, the inner liner 3 is fixedly connected to the rear suspension strip 11, the rear suspension strip 11 is connected to the helmet body 1 by the first rear positioning pin 12, and the rear suspension strip 11 is slidably engaged with the first rear positioning pin 12.
[0053] It should be noted that the inner liner 3 is fixedly connected to the rear suspension strip 11. When the adjuster 2 pulls the thread 10 to shrink the inner liner soft rubber frame 4, the force is transmitted to the inner liner 3 through the front suspension frame 6. The rear suspension strip 11, while slidingly engaged with the helmet body 1, can slide along the direction of the first rear positioning pin 12, thereby moving the inner liner 3 within a certain range to achieve a better fit. The sliding engagement method allows the rear suspension strip 11 to move in a certain direction while restricting its displacement in other directions, ensuring the stability of the structure. This design allows the inner liner 3 to adjust its position more flexibly under the action of the adjuster 2 to better adapt to changes in head position, while ensuring the stability and reliability of the connection.
[0054] In one embodiment of this application, a rear suspension bracket 9 is fixedly connected to one side of the adjuster 2, and the rear suspension bracket 9 is fixedly connected to the helmet body 1 by a second rear positioning pin 13.
[0055] It should be noted that the second rear positioning pin 13 and the rear suspension bracket 9 provide a fixed support point for the adjuster 2, which can be used as support when the adjuster 2 is contracted and tightened.
[0056] In one embodiment of this application, the rear suspension bracket 9 has a V-shaped structure, with its tip connected to the helmet body 1 and the other two ends connected to the adjuster 2.
[0057] It should be noted that the V-shaped structure has good mechanical properties. When the helmet 1 is impacted and the adjuster 2 exerts a pulling or pushing force on the rear suspension 9, the V-shaped structure can effectively distribute the force to the tip and then transmit it to the helmet 1. Compared with other shapes of suspensions, the V-shaped structure is more stable and efficient in the process of force transmission and can ensure uniform force distribution.
[0058] In one embodiment of this application, the inner wall of the helmet body 1 is provided with a mounting groove, which corresponds to the structure of the front positioning pin 5, the middle positioning pin 8, the first rear positioning pin 12 and the second rear positioning pin 13 respectively.
[0059] It should be noted that during the helmet production and assembly process, the front positioning pin 5, the middle positioning pin 8, the first rear positioning pin 12 and the second rear positioning pin 13 are respectively installed into the mounting grooves on the inner wall of the helmet body 1, which facilitates the installation of the inner liner 3 and the inner liner soft rubber frame 4.
[0060] In one embodiment of this application, hook and buckle structures are provided at equal intervals on the outer wall of the inner soft rubber frame 4, and the thread 10 is embedded in the hook and buckle structures.
[0061] It should be noted that the hook and loop structure works in conjunction with the thread 10. After the thread 10 is embedded in the hook and loop structure, the shape and structure of the hook and loop structure can hold the thread 10 in place, preventing it from slipping or falling off. Due to the equidistant arrangement of the hook and loop structures, when the adjuster 2 pulls the thread 10, the thread 10 transmits the force evenly to various parts of the inner soft rubber frame 4 through each hook and loop structure, so that the inner soft rubber frame 4 can contract or expand in the expected manner, ensuring the consistency and stability of the adjustment effect.
[0062] In one embodiment of this application, the regulator 2 includes a first rack 21 and a second rack 22, which are respectively connected to the two ends of the wire 10;
[0063] Gears 23 are meshed between the first rack 21 and the second rack 22, and a knob 24 is fixedly connected to the gear 23.
[0064] It should be noted that when the wearer rotates the knob 24, according to the gear transmission principle, the gear 23 coaxial with the knob 24 will rotate accordingly. Since the first rack 21 and the second rack 22 are respectively engaged with the gear 23, during the rotation of the gear 23, the first rack 21 and the second rack 22 will move in opposite directions in a straight line under the drive of the gear 23 teeth. Since the first rack 21 and the second rack 22 are respectively connected to the two ends of the wire 10, their movement will directly pull or release the wire 10. The wire 10 is wrapped around the inner soft rubber frame 4. As the wire 10 is pulled in and out, the inner soft rubber frame 4 will shrink or expand accordingly, thereby adjusting the internal space of the helmet. It should be further noted that the knob 24 is rotated on the outer shell of the adjuster 2 and is connected to the adjuster 2 through a releasable ratchet mechanism, which can be fixed or unfixed at any time after adjustment.
[0065] The above are merely preferred embodiments of this application and do not constitute any limitation on this application. Any person skilled in the art can make many possible variations and modifications to the technical solution of this application, or modify it into equivalent embodiments, without departing from the scope of the technical solution of this application. Therefore, all equivalent changes made based on the shape, structure, and principle of this application without departing from the content of the technical solution of this application should be covered within the protection scope of this application.
