Description

Technical Field

[0001] This utility model relates to the field of sports protective equipment technology, and in particular to the inner lining structure of ice hockey helmets. Background Technology

[0002] The inner lining of an ice hockey helmet is the internal structure located inside the outer shell of the helmet and in direct contact with the user's head. It is a composite structure containing various components such as cushioning materials, sweat-absorbing materials, and soft and comfortable materials. It absorbs and disperses the impact force on the head through cushioning materials, reducing the risk of injury.

[0003] For example, Chinese Patent Publication No. CN212661192U discloses an integrated anti-impact hockey helmet, which includes a helmet body. The helmet body is round and is formed by one-piece molding. The top center of the helmet body is recessed to form a low wind resistance zone, which extends from the front end of the helmet body to the rear end.

[0004] In the intense competition of ice hockey, players are often moving at high speeds and vying for possession, significantly increasing the probability of collisions. In the event of a collision, a player's helmet is highly likely to violently impact surrounding hard objects, such as ice barriers, other players' bodies, or hard hockey sticks. This powerful impact can severely damage a player's body, potentially causing abrasions, bruises, and other injuries. More seriously, it can lead to concussions, posing a significant threat to a player's health. Utility Model Content

[0005] The purpose of this invention is to solve the problem in the existing technology that when players collide, their brains are concussed, posing a great threat to their physical health, and to propose an inner lining structure for ice hockey helmets.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: an ice hockey helmet liner structure, including a helmet body, an inner liner body inside the helmet body, symmetrically arranged circular holes on the outer side of the helmet body, a connecting rod movably engaged inside the circular holes, the other end of the connecting rod movably engaged on one side of the inner liner body, a spring provided on the outer side of the connecting rod, and a shock-absorbing pad mounting groove fixedly connected to the middle of the outer side of the inner liner body, with a shock-absorbing foam pad fixedly installed inside the shock-absorbing pad mounting groove.

[0007] Preferably, a baffle is threaded to the other end of the connecting rod.

[0008] Preferably, one side of the shock-absorbing foam pad is fixedly connected with a Velcro surface.

[0009] Preferably, a Velcro hook is fixedly connected to the middle of the inner side of the helmet body.

[0010] Preferably, the outer side of the helmet body is symmetrically provided with several No. 1 heat dissipation vents, and cooling modules are fixedly installed inside the various No. 1 heat dissipation vents. The outer side of the inner liner body is symmetrically provided with several No. 2 heat dissipation vents.

[0011] Preferably, the cooling module includes a mounting bracket, a micro-semiconductor cooling chip, and a power supply connector. The input end of the micro-semiconductor cooling chip is electrically connected to the input end of the power supply connector, and the input end of the power supply connector is electrically connected to the helmet's built-in battery.

[0012] Preferably, the mounting bracket has a cooling chip mounting slot inside, and the micro semiconductor cooling chip is fixedly mounted inside the cooling chip mounting slot.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0014] In this invention, the inner liner body slides relative to the helmet body and compresses the spring to provide cushioning. At the same time, the shock-absorbing foam pad absorbs the energy generated by the impact through deformation, dispersing the large impact force that was originally concentrated on a certain point of the head to the entire area in contact with the inner liner body, thereby reducing the pressure on the head and protecting the athlete's head.

[0021] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0022] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0023] Example 1: As Figure 1 - Figure 4 As shown, this utility model provides an inner liner structure for an ice hockey helmet, including a helmet body 1, an inner liner body 2 inside the helmet body 1, symmetrically arranged circular holes 11 on the outer side of the helmet body 1, a connecting rod 12 movably connected inside the circular holes 11, the other end of the connecting rod 12 movably connected to one side of the inner liner body 2, a spring 121 on the outer side of the connecting rod 12, a shock-absorbing pad mounting groove 21 fixedly connected to the middle of the outer side of the inner liner body 2, a shock-absorbing foam pad 211 fixedly installed inside the shock-absorbing pad mounting groove 21, a plurality of first-level heat dissipation vents 13 symmetrically arranged on the outer side of the helmet body 1, cooling modules 14 fixedly installed inside the plurality of first-level heat dissipation vents 13, a plurality of second-level heat dissipation vents 22 symmetrically arranged on the outer side of the inner liner body 2, a baffle 122 threadedly connected to the other end of the connecting rod 12, a Velcro surface 212 fixedly connected to one side of the shock-absorbing foam pad 211, and a Velcro hook surface 15 fixedly connected to the middle of the inner side of the helmet body 1.

[0024] The specific settings and functions of this embodiment are described below. When a hockey player wearing the hockey helmet liner structure is impacted, the liner body 2 slides relative to the helmet body 1. Simultaneously, the spring 121 on the outside of the connecting rod 12 is compressed by the helmet body 1, converting the impact energy into elastic potential energy, which is stored inside the spring 121. Subsequently, the spring 121 returns to its original position, and its stored elastic potential energy is gradually released, causing the liner body 2 to begin sliding in the opposite direction, returning to its initial relative position, reducing the impact force transmitted to the athlete's head. At the same time, the shock-absorbing foam pad 211 rapidly deflects upon impact. Deformation absorbs the energy generated by the impact through its own compression deformation, dispersing the large impact force that was originally concentrated on a certain point of the head to the entire area in contact with the foam pad and the inner liner body 2, thereby reducing the pressure on the head and protecting the athlete's head. When it is necessary to disassemble and clean the inner liner body 2, rotate the disassembly plate 122 to release the restriction of the connecting rod 12 on the inner liner body 2, and then take the inner liner body 2 out of the helmet body 1. The Velcro hook side 15 and the Velcro nap side 212 are separated, and the athlete can clean, dry or replace the damaged module to maintain the hygiene of the inner liner.

[0025] Example 2: Figure 1 - Figure 5 As shown, the inner lining structure of this utility model for an ice hockey helmet includes a helmet body 1, an inner lining body 2 inside the helmet body 1, symmetrically arranged circular holes 11 on the outer side of the helmet body 1, a connecting rod 12 movably engaged inside the circular holes 11, the other end of the connecting rod 12 movably engaged on one side of the inner lining body 2, a spring 121 on the outer side of the connecting rod 12, a shock-absorbing pad mounting groove 21 fixedly connected to the middle of the outer side of the inner lining body 2, a shock-absorbing foam pad 211 fixedly installed inside the shock-absorbing pad mounting groove 21, and several No. 1 heat dissipation vents 13 symmetrically arranged on the outer side of the helmet body 1. Cooling modules 14 are fixedly installed inside several No. 1 heat dissipation vents 13. Several No. 2 heat dissipation vents 22 are symmetrically opened on the outer side of the inner lining body 2. The cooling module 14 includes a mounting bracket 141, a micro semiconductor cooling chip 142 and a power supply connector 143. The input end of the micro semiconductor cooling chip 142 is electrically connected to the input end of the power supply connector 143. The input end of the power supply connector 143 is electrically connected to the helmet's built-in battery. A cooling chip mounting slot 144 is opened inside the mounting bracket 141. The micro semiconductor cooling chip 142 is fixedly installed inside the cooling chip mounting slot 144.

[0026] The overall effect of this embodiment is that when ice hockey players are engaged in high-intensity exercise, the helmet's built-in battery powers the micro-semiconductor cooling chip 142 via the power connector 143. The micro-semiconductor cooling chip 142 then begins to cool the ice hockey player. Outside air enters the interior of the ice hockey helmet's inner lining structure through the first heat dissipation vent 13 and the second heat dissipation vent 22, accelerating the internal gas flow. This causes the cool air near the micro-semiconductor cooling chip 142 to flow to the athlete's temples for cooling and heat dissipation, reducing the irritability and fatigue caused by the heat.

[0027] The device's usage and working principle are as follows: When an ice hockey player wearing the inner lining of this helmet is impacted, the inner lining body 2 slides relative to the helmet body 1. Simultaneously, the spring 121 on the outside of the connecting rod 12 is compressed by the helmet body 1, converting the impact energy into elastic potential energy, which is stored inside the spring 121. Subsequently, the spring 121 returns to its original position, and its stored elastic potential energy is gradually released, causing the inner lining body 2 to begin sliding in the opposite direction, returning to its initial relative position, thus reducing the impact force transmitted to the athlete's head. At the same time, the shock-absorbing foam pad 211 deforms rapidly at the moment of impact, absorbing the energy generated by the impact through its own compression deformation. This disperses the large impact force that was originally concentrated on a certain point of the head to the entire area in contact between the foam pad and the inner lining body 2, thereby reducing the local pressure on the head.

[0028] When it is necessary to disassemble and clean the inner liner body 2, rotate the disassembly baffle 122 to release the limiting position of the connecting rod 12 on the inner liner body 2, and then take the inner liner body 2 out from the inside of the helmet body 1, separating the hook and loop fastener 15 from the loop fastener 212.

[0029] During high-intensity exercise, the helmet's built-in battery powers the micro-semiconductor cooling chip 142 via power connector 143. The micro-semiconductor cooling chip 142 then begins to cool the area. Outside air enters the helmet's inner lining structure through heat dissipation vents 13 and 22, accelerating the internal gas flow. This allows the cool air near the micro-semiconductor cooling chip 142 to flow to the athlete's temples for cooling and heat dissipation, reducing the irritability and fatigue caused by the heat.

[0030] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
