Description

Technical Field

[0001] This utility model relates to a helmet chin guard, specifically a ski helmet chin guard for protecting the lower jaw. Background Technology

[0002] People can reach speeds of 40km / h to 60km / h while skiing. In order to protect their heads, they need to wear ski helmets. One of the most important structures on a ski helmet is the chin guard, which is a key component for protecting the chin and face. It can effectively reduce impact injuries, especially in high-intensity skiing.

[0003] Existing ski helmet chin guards have a complex and poorly designed structure. Currently, they are mostly fixed to the helmet with screws. While this method ensures stability, the chin guard cannot be quickly removed from the helmet for different skiing activities, and it is inconvenient to clean when dirty, leading to difficulties in subsequent cleaning and maintenance and a poor user experience. Therefore, the inventor has improved the structure of the ski helmet chin guard. Utility Model Content

[0004] The purpose of this utility model is to provide a chin guard for ski helmets to protect the chin. This chin guard has the advantages of simple structure, reasonable design, quick-release function, making it easier to install and remove, easier to clean, and better user experience, thus solving the problems mentioned in the above technical background.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a chin guard for ski helmets, comprising a chin guard body and a cover plate disposed on the chin guard body. The chin guard body includes a chin guard strap and a positioning plate fixed to the chin guard strap. The positioning plate includes a plate body with a through hole and a locking groove disposed within the through hole. The cover plate includes an outer shell and a rotating block disposed at one end of the outer shell near the positioning plate. The rotating block passes through the through hole from the outside to the inside and is engaged in the locking groove. The rotating block is rotatable. When the rotating block is engaged in the locking groove, the end of the rotating block away from the outer shell passes through the positioning plate and enters the helmet shell, where it is engaged in the locking groove, allowing both the chin guard body and the cover plate to be suspended on the helmet. When the helmet enters the through hole, the rotating block can be removed from the positioning plate, thereby removing the chin guard body and the cover plate. This provides a quick-release effect for the chin guard, making disassembly and assembly more convenient and improving the user experience.

[0006] Preferably, there are two positioning plates, and the two positioning plates are fixed to both ends of the chin guard.

[0007] Preferably, the jaw protector is U-shaped, with a positioning plate embedded in it, and both ends of the positioning plate passing through both ends of the jaw protector, so that both ends of the positioning plate are exposed to the outside.

[0008] Preferably, the through hole and the locking groove are arranged in a cross shape, and the depth of the locking groove is between 1 mm and 1.5 mm.

[0009] Preferably, there are two cover plates, which are symmetrically arranged at both ends of the chin guard body. The two cover plates are respectively arranged on both sides of the helmet, so that both ends of the chin guard body can be fixed to the helmet and remain stable.

[0010] Preferably, a connecting post is provided between the outer shell and the rotating block. The two ends of the connecting post are fixedly connected to the outer shell and the rotating block, respectively. The connecting post needs to pass through the through hole and extend into the interior of the helmet so that the rotating block can be snapped into the interior of the helmet shell. However, the rotating block will not enter the cavity of the helmet, and the rotating block will not touch the user's head during use.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

Those skilled in the art can understand the specific meaning of the above terms in this embodiment of the invention according to the specific circumstances.

[0026] Please see Figure 1 This utility model provides an embodiment of a ski helmet chin guard for protecting the chin. The ski helmet chin guard includes a chin guard body 1 and a cover plate 2 disposed on the chin guard body 1. The cover plate 2 locks the chin guard body 1 onto the helmet. The structure of the helmet is prior art and will not be described in detail here. There are two cover plates 2, which are symmetrically disposed at both ends of the chin guard body 1. The two cover plates 2 are respectively disposed on both sides of the helmet, so that both ends of the chin guard body 1 can be fixed onto the helmet and remain stable. Both cover plates 2 fit against the outer side of the helmet shell and do not appear too abrupt, making the overall structure more aesthetically pleasing.

[0027] Please see Figure 2 With cover plate 2 in Figure 1 The position shown is the reference position. After rotating the cover plate 2 by 90°, the desired position is obtained. Figure 2 In the state shown, the cover plate 2 can be removed from the helmet and separated from the chin guard body 1, so that the chin guard body 1 can also be removed from the helmet for cleaning and other operations. It can be seen that the chin guard body 1 is fixed to the helmet by means of the cover plate 2.

[0028] Please see Figure 3 The jaw protector body 1 includes a jaw protector strap 11 and a positioning plate 12 fixed on the jaw protector strap 11. The jaw protector strap 11 is U-shaped. There are two positioning plates 12, and the two positioning plates 12 are fixed to both ends of the jaw protector strap 11 respectively. The positioning plates 12 are embedded in the jaw protector strap 11, and both ends of the positioning plates 12 pass through both ends of the jaw protector strap 11, so that both ends of the positioning plates 12 are exposed to the outside.

[0029] Please see Figure 4The cover plate 2 includes an outer shell 21 and a rotating block 22 disposed at one end of the outer shell 21 near the positioning plate 12. A connecting post 23 is provided between the outer shell 21 and the rotating block 22. The two ends of the connecting post 23 are fixedly connected to the outer shell 21 and the rotating block 22 respectively. In actual use, the connecting post 23 needs to pass through the through hole 122 and extend into the interior of the helmet so that the rotating block 22 can be snapped into the interior of the helmet shell. However, the rotating block 22 will not enter the cavity of the helmet. In use, the rotating block 22 will not touch the user's head.

[0030] Please see Figure 5 The positioning plate 12 includes a plate body 121, with a through hole 122 through the plate body 121 and a locking groove 123 inside the through hole 122. A rotating block 22 passes through the through hole 122 from the outside to the inside and is engaged in the locking groove 123. The rotating block 22 is rotatable. The through hole 122 and the locking groove 123 form a cross shape. When the rotating block 22 is engaged in the locking groove 123, the end of the rotating block 22 away from the outer shell 21 passes through the positioning plate 12 and enters the helmet shell, where it is engaged in the locking groove 123. This allows both the chin guard body 1 and the cover plate 2 to be suspended on the helmet. When the helmet enters the through hole 122, the rotating block 22 can be removed from the positioning plate 12, allowing the chin guard body 1 and the cover plate 2 to be removed. This provides a quick-release effect for the helmet chin guard, making disassembly and assembly more convenient and improving the user experience. When the cover plate 2 is in... Figure 1 In the locked state shown, the rotating block 22 is positioned exactly within the locking groove 123, at which point the cover plate 2 locks the chin guard body 1 onto the helmet.

[0031] Please see Figure 6 When unlocking is required, the operator needs to forcefully press the cover plate 2 towards the helmet side, causing the rotating block 22 to be pressed towards the helmet side by 1mm to 1.5mm, thus disengaging the rotating block 22 from the locking groove 123. Then, rotating the outer shell 21, the rotating block 22, and the connecting post 23 by 90° will move the rotating block 22 to the desired position. Figure 6 In the state shown, the rotating block 22 is completely moved into the through hole 122. The outer shell 21 is pulled out away from the helmet, and the cover plate 2 can be removed from the helmet shell as a whole, and then the chin guard body 1 can be removed.

[0032] Please see Figure 7 , Figure 7This is a schematic diagram of a helmet shell, in which an adapter hole 3 is provided. A through hole 122 extends into the interior of the helmet shell, but does not completely penetrate it. Both the through hole 122 and the locking groove 123 are located inside the adapter hole 3. The size and shape of the adapter hole 3 are exactly the same as those of the through hole 122, both being straight. The locking groove 123 is located inside the adapter hole 3, i.e., inside the helmet shell, and its depth is between 1mm and 1.5mm. When the rotating block 22 rotates 90° within the adapter hole 3, it can move to... Figure 5 At the indicated position, stretching the outer shell 21 away from the helmet shell will press the rotating block 22 into the locking groove 123. The rotating block 22 and the locking groove 123 are connected and locked by friction, so that the cover plate 2 is fixed on the helmet and cannot move. If it needs to be disassembled later, the person needs to manually press the cover plate 2 towards the helmet and then rotate it 90° to unlock it.

[0033] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
