Description

Technical Field

[0001] The invention relates to the technical field of helmets, in particular to a foldable vibration-reducing helmet with a non-Newtonian fluid liner. Background Art

[0002] According to laws and regulations, people must wear helmets when using motorcycles. People also wear helmets when using bicycles and electric vehicles. Helmets can well protect the head and reduce impact injuries in the event of an accident. At present, most helmets usually have the following disadvantages when used: First, the helmet shell does not have a good ventilation function. In order to ensure the overall structural strength of the shell, a number of small ventilation holes are opened on the side. If the riding speed is slow during use, the air intake will be very small and no circulation can be formed inside, resulting in the sweat of the user when tired Wetting the lining of the helmet, making the inside of the helmet smelly and unable to keep the helmet dry; Second, most helmets are fixed and non-adjustable. When the helmet is not needed, due to the large size of the helmet, a large storage area is required when placing the helmet, and it is not convenient to carry; Third, the helmet realizes the functions of sweat absorption and vibration reduction by filling sponge and other fillers between the shell and the lining, but the sweat absorption degree can only be kept within a certain range, and the vibration reduction and recovery effects are not obvious when encountering strong external forces.

When the external impact vibration becomes stronger, rotating component 1 abuts against the non-Newtonian fluid vibration-damping capsule. The non-Newtonian fluid vibration-damping capsule is flattened by the force, and the non-Newtonian fluid filled inside resists deformation by the force, allowing it to quickly recover its deformation. This is repeated to achieve the effect of rapid vibration reduction. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0022] like Figures 1 to 7As shown, a foldable vibration-damping helmet with a non-Newtonian fluid lining comprises a protective helmet 1 and a helmet front brim 2, wherein the protective helmet 1 is a notched ring-belt structure, the helmet front brim 2 is fixed to the upper end of the notch position of the protective helmet 1, and two symmetrically arranged buckle straps 3 are fixed to the lower end of the protective helmet 1, a rotating component 1 4 and a rotating component 2 5 are installed on the inner side of the protective helmet 1, the rotating component 1 4 and the rotating component 2 5 are connected through a main support frame 6, a plurality of evenly distributed buckles 1 7 are installed on the lower end of the rotating component 1 4, a slot 1 8 is provided on the inner side of the protective helmet 1, and a plurality of the buckles 1 7 can be snapped into the slot 1 8 and used to form a helmet shell with the rotating component 1 4, the rotating component 2 5 is placed on the inner side of the rotating component 1 4 and a plurality of evenly distributed buckles 2 9 are installed on the lower end, a slot 2 10 is provided on the inner side of the protective helmet 1 below the slot 1 8, and a plurality of the buckles 2 9 can be snapped into the slot 2 10 and used to form a helmet lining with the rotating component 2 5.

[0023] In this embodiment, the rotating component 4 includes a roller 401, a rotating body 402 and a flat bearing 403. There are two rollers 401 and one end of the rollers 401 is fixed to the inner side of the helmet 1 by bolts, and the other end of the roller 401 is fixed to the main support frame 6. There are several rotating bodies 402 and their diameters gradually increase from the middle to the two ends. There are several flat bearings 403 and they are evenly installed on the roller 401. The ends of several rotating bodies 402 are fixed on the flat bearing 403. Breathable and waterproof fabrics 404 are arranged between adjacent side ends of several rotating bodies 402, and the lower end of the outermost rotating body 402 is connected to the buckle 7.

[0024] It should be noted that the breathable and waterproof fabric 404 is connected between the central axis beams of the rotating body 402. When it shrinks, it will fold layer by layer, which will not affect the shrinkage of the helmet. It plays a breathable role in the unfolded state and will not get the head wet on rainy days.

[0025] In this embodiment, the rotating component 2 5 includes a roller 2 501, a rotating body 2 502 and a flat bearing 2 503. The roller 2 501 has two and the ends are fixed to the other end of the main support frame 6. The rotating body 2 502 has several and the diameter thereof gradually increases from the middle to the two ends. The flat bearing 2 503 has several and is evenly installed on the roller 2 501. The ends of several rotating bodies 2 502 are fixed on the flat bearing 2 503. The lower end of the outermost rotating body 2 502 is connected to the buckle 2 9. The arc-shaped outer surface of the rotating body 2 502 is provided with a capsule groove 504, and a non-Newtonian fluid vibration-damping capsule 505 is slidably arranged in the capsule groove 504.

[0026] It is worth noting that the number of rollers 401 corresponds to the number of rotating bodies 402, and the number of rollers 501 corresponds to the number of rotating bodies 502. Both ends of the main support frame 6 are fixed on rollers 401 and 501. When flat bearings 403 and 503 rotate while the rollers do not move, the main support frame 6 is in a fixed state to ensure the reliable structural strength of the helmet as a whole. After loosening the locking bolts, the main support frame 6 can rotate, thereby driving the folded helmet shell and helmet lining to be gathered together.

[0027] In this embodiment, the rotating body 1 402 and the rotating body 2 502 are both made of vibration-damping material, and the breathable and waterproof fabric 404 between the rotating body 1 402 corresponds to the capsule groove 504 on the rotating body 2 502 .

[0028] In this embodiment, the vertical projection of the capsule groove 504 is a rectangle, the sliding limit of the non-Newtonian fluid vibration-damping capsule 505 is located in the capsule groove 504, the interior of the non-Newtonian fluid vibration-damping capsule 505 is provided with a non-Newtonian fluid liquid 506, and a gap is left between the upper end of the non-Newtonian fluid vibration-damping capsule 505 and the helmet shell.

[0029] It is worth mentioning that the non-Newtonian fluid 506 is filled in the non-Newtonian fluid vibration-damping capsule 505, so that it maintains a spherical state when it is not subjected to external vibration or impact.

[0030] In addition, compression springs are provided on the buckle 1 7 and the buckle 2 9, and the other end of the compression spring is connected to the slot 1 8 and the slot 2 10. The buckle can be snapped into the corresponding slot by pressing the inclined end.

[0031] Working process and principle: The rider wears the helmet under the condition that riding is required. During the use of the present invention, the telescopic helmet shell and the helmet lining need to be extended to the specified state first, specifically, the main support frame 6 is rotated to the vertical state relative to the helmet, the locking nut is tightened to fix it, and the buckle 1 7 and the buckle 2 9 are pulled respectively until they are connected to the card slot 1 8 and the card slot 2 10. Under the condition that there is no error, the buckle 3 is buckled and the riding can be carried out;

[0032] During riding, if an emergency occurs and the rider's head is hit, the first to be hit by the external force is the rotating body 402 on the helmet shell. Since there is a certain distance between the rotating bodies 402, the rider's head will not be directly hit by a large external object. After the impact causes further deformation of the helmet shell, it will touch and abut the non-Newtonian fluid vibration-damping capsule 505. The non-Newtonian fluid vibration-damping capsule 505 is first flattened, and then the non-Newtonian fluid filled inside resists the deformation, so that it quickly recovers its shape. This is repeated to achieve fast recovery. The effect of rapid vibration reduction is achieved. When a small foreign object hits the taut breathable waterproof fabric 404, it will be directly blocked by the rotating body 2 502 corresponding to the breathable waterproof fabric 404, thereby reducing unnecessary damage. After riding, the rider can first rotate the rotating body 2 502 in the helmet lining into one piece, and then rotate the rotating body 1 402 in the helmet shell into one piece, which is convenient for taking and placing and does not take up a large space. Of course, the buckles can also be completely removed from the corresponding slots, that is, the helmet lining and the helmet shell are completely removed, which is convenient for cleaning and step-by-step storage.

[0033] Based on the above, the present invention realizes an all-round ventilation environment at the side and top of the helmet by arranging a ventilated waterproof cloth 404 on the foldable helmet shell, and arranging a non-Newtonian fluid vibration-damping capsule 505 on the foldable helmet lining by sliding and limiting. After the wind passes through the ventilated waterproof cloth 404, a turbulent flow is formed in the capsule groove 504 on the helmet lining, thereby driving the non-Newtonian fluid vibration-damping capsule 505 to rotate in the capsule groove 504 and slide back and forth irregularly, so as to achieve the purpose of removing the sweat on the head and making it evaporate more quickly, and at the same time, the rider's head can be massaged;

[0034] By providing the rotating assembly 1 4 and the rotating assembly 2 5, the helmet shell and the helmet lining can be folded. The folded helmet is kept within the range of the helmet in terms of height and thickness, and is shrunk into an integral ring structure with the helmet front brim 2, which is convenient for storage and storage. The helmet lining can be completely removed by taking out the buckle from the corresponding card slot, which is convenient for cleaning and storage.

[0035] By setting up a main support frame 6, and connecting the rotating component 1 4 and the rotating component 2 5 through the main support frame 6, the overall structural strength of the helmet is ensured. The rotating body 1 402 and the rotating body 2 502 are both made of vibration-damping materials. When the helmet encounters a relatively low vibration external force, it can rely on its own vibration reduction. When the external impact vibration becomes stronger, the rotating component 1 4 abuts against the non-Newtonian fluid vibration-damping capsule 505. The non-Newtonian fluid vibration-damping capsule 505 is flattened by the force, and the non-Newtonian fluid 506 filled inside resists the deformation by the force, so that it quickly recovers the deformation, and this is repeated to achieve the effect of rapid vibration reduction.

[0036] It is known from common technical knowledge that the present invention can be implemented by other embodiments that do not deviate from its spirit or essential features. Therefore, the above disclosed embodiments are only illustrative in all respects and are not exclusive. All changes within the scope of the present invention or within the scope equivalent to the present invention are included in the present invention.
