Description

Technical Field

[0001] The utility model relates to the technical field of head protection, in particular to a helmet. Background Art

[0002] A helmet is a piece of equipment used to protect the head, which can reduce the risk of head injury and protect the head from external impact and injury.

[0003] Existing helmets generally consist of a shell and a cushioning structure within the shell. The shell is the outermost, hard shell structure of the helmet, dissipating the impact force during a collision, serving as the first line of defense for the head. The cushioning structure, typically an inner foam layer adjacent to the shell, absorbs the impact force during a collision, mitigating injuries and serving as a second line of defense for the head.

[0004] Helmets primarily provide head protection through their shell and internal cushioning structures. Shells are typically made of rigid materials such as steel, reinforced plastic, and fiberglass. Because helmets take up considerable space, they can be inconvenient to store and carry when not in use. For example, some helmets are too bulky to fit into the seat of an electric scooter or motorcycle when not in use, making them vulnerable to loss or environmental contamination. Utility Model Content

[0005] Based on this, the purpose of the present invention is to provide a helmet that aims to provide a certain protective function while being designed to be partially foldable for easy storage and carrying.

[0006] In order to achieve the above purpose, the technical solution adopted by the present utility model is as follows:

[0007] The utility model provides a helmet, comprising a hard top shell, a soft rear shell, and two groups of soft side shells. The hard top shell is provided with a first surrounding area that matches the contour of the top of the head. The soft rear shell is connected to the hard top shell. The soft rear shell can be bent and deformed. When the soft rear shell is stretched, the side of the soft rear shell close to the first surrounding area forms a second surrounding area that matches the contour of the back of the head. When the soft rear shell is bent, the soft rear shell bends and approaches the first surrounding area. The two groups of soft side shells are respectively arranged on two opposite sides of the hard top shell. The two groups of soft side shells are movably connected to the hard top shell. The soft side shells can be telescopically deformed and bent. When the soft side shells stretch along the peripheral extension direction of the first surrounding area, the soft side shells form a third surrounding area that matches the contour of the side of the head. When the soft side shells shrink along the peripheral extension direction of the first surrounding area, the soft side shells gather together. When the soft side shells are bent, the soft side shells bend and approach the first surrounding area.

[0008] The beneficial effects of the present invention include at least: the hard top shell, the soft back shell and the two groups of soft side shells are connected to form a wrapping area to protect the wearer's head; at the same time, since the soft back shell and the two groups of soft side shells can be bent and deformed to move closer to the surrounding area of ​​the hard top shell, the volume of the helmet occupied by the soft back shell and the two groups of soft side shells is reduced, thereby facilitating carrying and storage; in addition, the soft side shells can also be stretched and deformed, so that when the helmet is not in use, the soft side shells can be contracted first, and then the soft side shells can be bent and deformed as a whole to move closer to the surrounding area of ​​the hard top shell, thereby further reducing the volume of the helmet occupied by the soft side shells.

[0009] In addition, the helmet according to the present invention may also have the following additional technical features:

[0010] Furthermore, the edges of the opposite sides of the hard top shell are provided with rail grooves, and the soft side shells are provided with clamping blocks, which are slidably clamped in the rail grooves.

[0011] Furthermore, the helmet also includes a soft front shell, which is connected to the hard top shell and is located on the side opposite to the hard top shell and the soft rear shell. The soft front shell can bend and deform. When the soft front shell is stretched, the soft front shell forms a fourth surrounding area that matches the contour of the forehead. When the soft front shell is bent, the soft front shell bends and approaches the first surrounding area.

[0012] Furthermore, the ends of the two soft side shells that are telescopically deformed on the same side are fixed to the soft front shell, and the other ends of the two soft side shells that are telescopically deformed are buckled to the soft rear shell.

[0013] Furthermore, the soft rear shell is provided with a through slot, the same side ends of the two soft side shells that are telescopically deformed are fixed on the soft front shell, and the other ends of the two soft side shells that are telescopically deformed are passed through the through slot and buckled together.

[0014] Furthermore, the two soft side shells are buckled together through a size adjustment structure.

[0015] Furthermore, a lower jaw locking mechanism is provided on the hard top shell.

[0016] Furthermore, the chin locking mechanism includes two groups of straps and an adjusting buckle. The two groups of straps are respectively fixed to opposite sides of the hard top shell, and the two ends of the adjusting buckle are respectively connected to the free ends of the straps.

[0017] Furthermore, at least one of the hard top shell, the soft rear shell and the soft side shell is provided with heat dissipation holes.

[0018] Furthermore, a crush energy absorption structure is provided inside the soft side shell. BRIEF DESCRIPTION OF THE DRAWINGS

The terms used herein in the specification of this invention are intended only to describe specific embodiments and are not intended to limit the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0030] In existing helmets, since the helmet shell is usually made of rigid material, the space occupied by the helmet cannot be adjusted, which makes it very inconvenient to store and carry the helmet when not being worn. Therefore, the utility model provides a helmet that can be partially folded when storing and carrying the helmet, thereby reducing the size of the helmet to a certain extent and reducing the space occupied by the helmet.

[0031] For details, please refer to Figures 1 to 4 , is a helmet provided by the present invention, comprising a hard top shell 100, a soft rear shell 200, and two sets of soft side shells 300.

[0032] The hard top shell 100 has a first surrounding area 110 that matches the contour of the top of the head, thereby wrapping and protecting the top of the head. To ensure that the hard top shell 100 can provide protection in the event of an impact, the hard top shell 100 needs to have a certain structural strength. Optionally, the hard top shell 100 can be made of a hard material such as steel, reinforced plastic, or fiberglass.

[0033] The soft rear shell 200 is positioned behind the hard top shell 100 to protect the back of the head. The soft rear shell 200 is capable of bending and deforming. Specifically, when the soft rear shell 200 is extended, its inner side forms a second surrounding area 210 that matches the contour of the back of the head, thereby wrapping and protecting the back of the head. When the soft rear shell 200 is bent, it bends closer to the first surrounding area 110, reducing the space occupied by the soft rear shell 200 at the back of the helmet. It should be noted that the aforementioned bent state can be that the portion of the soft rear shell 200 not connected to the hard top shell 100 is directly concave inward and close to the first surrounding area 110, or it can be concave inward after being folded multiple times and close to the first surrounding area 110. It should also be pointed out that the soft rear shell 200 close to the first surrounding area 110 can be that the soft rear shell 200 partially extends into the first surrounding area 110, or it can be that the soft rear shell 200 is located outside the first surrounding area 110, but it must be ensured that the space occupied by the soft rear shell 200 is reduced compared to the state before the bending. In order to enable the soft rear shell 200 to bend and deform, the soft rear shell 200 can be made of a soft, impact-resistant material, such as a high-quality polypropylene double-wall material.

[0034] There are two groups of soft side shells 300, and the two groups of soft side shells 300 are respectively arranged on the left and right sides of the hard top shell 100. The two groups of soft side shells 300 are movably connected to the hard top shell 100, and the soft side shells 300 can be stretched and deformed and bent, which is specifically manifested in: when the soft side shells 300 stretch along the peripheral extension direction of the first surrounding area 110, the inner side of the soft side shell 300 forms a third surrounding area 310 that matches the contour of the side of the head, so that the side of the head can be wrapped and protected; when the soft side shells 300 shrink along the peripheral extension direction of the first surrounding area 110, the soft side shells 300 can gather together, thereby reducing the side space occupied by the helmet; when the soft side shells 300 bend, the soft side shells 300 bend and approach the first surrounding area 110.

[0035] It should be noted that the aforementioned bending state can be that the part of the soft side shell 300 that is not connected to the hard top shell 100 is directly recessed inward and close to the first surrounding area 110, or it can be recessed inward and close to the first surrounding area 110 after multiple folds, or it can be that after the soft side shells 300 are gathered together, the end of the soft side shell 300 away from the hard top shell 100 is bent inward and close to the first surrounding area 110, or after the soft side shells 300 are gathered together, the middle part of the soft side shell 300 is bent inward and close to the first surrounding area 110.

[0036] It should also be noted that when the soft side shell 300 is positioned near the first surrounding area 110, the soft rear shell 200 can partially extend into the first surrounding area 110, or the soft rear shell 200 can be positioned outside the first surrounding area 110. However, the space occupied by the soft rear shell 200 in this state is reduced compared to when it is extended. To allow the soft side shell 300 to undergo tensile and bending deformation, the soft side shell 300 can be made of an impact-resistant soft material, such as a high-quality double-walled polypropylene material.

[0037] In some optional embodiments, such as Figure 3 As shown, rail grooves 120 are provided on the edges of the left and right sides of the hard top shell 100, and a card block (not shown in the drawings) is provided on the soft side shell 300, which is slidably engaged with the rail grooves 120. In this way, the soft side shell 300 can slide relative to the hard top shell 100, thereby protecting the side of the head when unfolded. The number of rail grooves 120 can be set to multiple, for example, two, and the two rail grooves 120 are arranged in parallel at intervals. Correspondingly, two groups of card blocks are also provided, and each group of card blocks is engaged in a corresponding rail groove 120. In addition, multiple spaced card blocks can be provided in each group of card blocks. For example, when there is only one card block in each group of card blocks, the card block can occupy the edge of the soft side shell 300 close to the hard top shell 100.

[0038] In some optional embodiments, such as Figures 1 to 4 As shown, the helmet also includes a soft front shell 400, which is connected to the front end of the hard top shell 100. The soft front shell 400 can bend and deform, specifically: when the soft front shell 400 is stretched, the soft front shell 400 forms a fourth surrounding area 410 that matches the contour of the forehead, thereby wrapping and protecting the forehead; when the soft front shell 400 is bent, the soft front shell 400 bends and approaches the first surrounding area 110, thereby reducing the front space occupied by the helmet.

[0039] It should be noted that the aforementioned bending state can be that the portion of the soft front shell 400 not connected to the hard top shell 100 directly concaves inwards and approaches the first surrounding area 110 , or it can be concaved inwards and approaches the first surrounding area 110 after being folded multiple times.

[0040] It should also be noted that the soft front shell 400 near the first surrounding area 110 can be partially extended into the first surrounding area 110, or it can be located outside the first surrounding area 110, but it must ensure that the space occupied by the soft front shell 400 is reduced compared to before the bending. In order to allow the soft side shell 300 to produce tensile and bending deformation, the soft side shell 300 can be made of an impact-resistant soft material, such as a high-quality double-walled polypropylene material.

[0041] In some optional embodiments, such as Figures 1 to 4 As shown, the front ends of the two soft side shells 300 are fixed to the soft front shell 400, and the rear ends of the two soft side shells 300 are buckled with the soft rear shell 200. At this time, the soft rear shell 200, the soft side shells 300 and the soft front shell 400 completely wrap the circumferential contour of the top of the head. Furthermore, in order to adjust the degree of clamping between the helmet and the top of the head, the part where the rear ends of the two soft side shells 300 are buckled with the soft rear shell 200 can be positionally adjustable. For example, different card blocks can be provided on the soft rear shell 200, and corresponding sockets for the card blocks to be engaged are provided on the soft side shells 300. The number of sockets can be equal to or different from the number of card blocks. For another example, a certain length of adhesive-backed Velcro can be provided on the soft rear shell 200, and a corresponding hook-surface Velcro can be provided on the soft side shells 300.

[0042] In some optional embodiments, such as Figure 3As shown, the soft rear shell 200 is provided with a through-slot 220. The front ends of the two soft side shells 300 are fixed to the soft front shell 400, and the rear ends of the two soft side shells 300 are inserted into the through-slot 220 and buckled together. At this time, the soft rear shell 200, the soft side shells 300, and the soft front shell 400 completely cover the circumferential contour of the top of the head. In this case, the rail slot 120 can be set completely through the through-slot 220, can also partially extend into the through-slot 220, or can be located outside the through-slot 220.

[0043] In some optional embodiments, to adjust the tightness of the helmet to the top of the head, the rear ends of the two soft side shells 300 are buckled together via a size adjustment structure (not shown in the drawings). Optionally, the size adjustment structure can be a ratchet bracket structure, a strap buckle structure, a plastic buckle structure, or a Velcro structure.

[0044] In some optional embodiments, such as Figure 3 As shown, in order to prevent the helmet from falling off the head during use, a lower jaw locking mechanism 130 is provided on the hard top shell 100. By providing the lower jaw locking mechanism 130, the state and position of the helmet can be assisted to prevent the helmet from being displaced or falling off due to activities or external forces.

[0045] In some optional embodiments, such as Figure 3 As shown, the chin locking mechanism 130 includes two sets of straps 131 and an adjustment buckle 132. The two sets of straps 131 are respectively fixed to the left and right sides of the hard top shell 100. For example, one end of each set of straps 131 can be fixed to the inner side of the hard top shell 100, and the two ends of the adjustment buckle 132 are respectively connected to the free ends of the straps 131. During use, the circumference of the straps 131 can be adjusted by adjusting the buckle 132 to ensure that the straps 131 are tightly against the wearer's chin. In this embodiment, the straps 131 can also be provided with a quick release structure to allow the helmet to be quickly removed in an emergency. For example, the quick release structure can use a quick adjustment buckle.

[0046] In some optional embodiments, such as Figures 1 to 4As shown, to improve the wearer's wearing comfort, heat dissipation holes 500 can be provided on the hard top shell 100, or on the soft rear shell 200, or on the soft side shell 300, or on both the hard top shell 100 and the soft rear shell 200, or on both the hard top shell 100 and the soft side shell 300, or on both the soft rear shell 200 and the soft side shell 300, or on both the hard top shell 100, the soft rear shell 200, and the soft side shell 300. Furthermore, the number, location, and size of the heat dissipation holes 500 can be adjusted based on actual needs.

[0047] In some optional embodiments, such as Figure 5 As shown, in order to improve the impact resistance of the soft side shell 300, a crush energy absorbing structure 330 is provided inside the soft side shell 300. When a collision occurs, the crush energy absorbing structure 330 can undergo plastic deformation, thereby absorbing and dispersing the collision energy and reducing the impact force transmitted to the wearer's head. Figure 2 As shown, the collapse energy absorbing structure 330 is a corrugated stacked structure. Of course, other structures, such as a honeycomb stacked structure, can also be selected. In addition, the collapse energy absorbing structure 330 can be made of expandable polystyrene material or foamed polypropylene material.
