Description

Technical Field

[0001] The utility model relates to the technical field of helmet linings, in particular to a detachable helmet lining. Background Technique

[0002] The motorcycle helmet lining is a key part that directly contacts the head inside the helmet. The lining closely fits the wearer's head contour. Through precise design and scientific material selection, it provides excellent protection for riders. The helmet lining ensures stable contact between the helmet and the head, reducing the risk of the impact force generated by vibration or collision directly acting on the head. At the same time, the design of the lining takes into account various dynamic factors during riding, such as the slight movement of the head, wind pressure changes, etc. By reasonably distributing the pressure points and optimizing the support structure, the wearer can maintain a sense of comfort even during long rides or high-speed driving. The lining also has excellent breathability and hygroscopicity, which can effectively regulate the head temperature and prevent discomfort and safety hazards caused by excessive sweating.

[0003] The Chinese patent with the publication number CN220898060U discloses a motorcycle helmet lining with enhanced protection, including: a helmet main body, a layer of air cushion layer is arranged inside the helmet main body to play a role in shock absorption; a lining structure, the lining structure is arranged inside the helmet main body through an installation structure and is in contact with the air cushion layer; a top guiding structure, the top guiding structure is arranged on the top of the helmet main body, and the locking end of the top guiding structure passes through the air cushion layer and is connected to the helmet main body. The installation structure includes installation grooves and installation blocks arranged around the inner bottom of the helmet main body; the installation blocks are arranged around the bottom of the lining structure and correspond to the positions of the installation grooves; positioning structures are arranged on the installation blocks, positioning holes are arranged on the installation grooves, and the installation blocks are positioned in the installation grooves through the positioning structures.

[0004] Although the above scheme can reduce the impact on the head and lower the risk of head injury, the helmet lining is integrally formed, making it difficult to disassemble and clean. As a result, after long-term use of the helmet, it is easy to accumulate sweat, odor, and bacteria, affecting the comfort and health of the wearer. At the same time, due to its integral formation, its structure size is fixed, making it inconvenient to adjust the head circumference size. Therefore, it does not meet the existing requirements, and for this reason, we propose a detachable helmet lining. Content of the Utility Model

[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0023] Please refer to Figures 1-4, the present utility model provides a technical solution: a detachable inner lining for a helmet, including a cap core 1. On the upper side of the inner wall of the cap core 1, a front crown 2 is provided. On the lower side of the inner wall of the cap core 1, a rear crown 3 is provided. On both sides of the inner wall of the cap core 1, side crowns 4 are provided.

[0024] During use, the front crown 2 is adhesively fixed to the first magic female sticker 5 of the cap core 1 through the first magic male sticker 8. The rear crown 3 is connected to the second magic female sticker 6 of the cap core 1 by using the second magic male sticker 9. The two side crowns 4 are adhesively bonded to the third magic female stickers 7 of the cap core 1 one by one through the third magic male stickers 10 at the rear ends, realizing a stable installation.

[0025] Please refer to Figure 3 and Figure 4 , six first magic female stickers 5 are sewn on the upper side of the front end of the cap core 1. Six first magic male stickers 8 are sewn on the rear end face of the front crown 2. And the first magic male sticker 8 and the first magic female sticker 5 are adhesively connected to each other. The precise alignment and firm adhesion between the first magic male sticker 8 and the first magic female sticker 5 ensure that the front crown 2 can be stably attached to the upper side of the cap core 1, not only improving the overall aesthetics of the inner lining, but also ensuring the stability and comfort during wearing;

[0026] Please refer to Figure 3 and Figure 4 , five second magic female stickers 6 are sewn on the lower side of the front end of the cap core 1. Five second magic male stickers 9 are sewn on the rear end face of the rear crown 3. And the second magic male sticker 9 and the second magic female sticker 6 are adhesively connected to each other. The tight combination between the second magic male sticker 9 and the second magic female sticker 6 enables the rear crown 3 to be accurately fixed on the lower side of the cap core 1, forming a stable support structure with the front crown 2, further enhancing the stability of the inner lining and the comfort during wearing;

[0027] Please refer to Figure 3 and Figure 4 , a group of third magic female stickers 7 are sewn on both sides of the upper and lower sides of the front end of the cap core 1, and each group of third magic female stickers 7 has two. A group of third magic male stickers 10 are sewn on the upper and lower sides of the rear end face of the side crown 4, and each group of third magic male stickers 10 has two. The third magic male stickers 10 are adhesively connected to the third magic female stickers 7. Through the all-round connection of multiple pairs of third magic male stickers 10 and third magic female stickers 7, the side crown 4 can be stably installed on both sides of the cap core 1, not only enhancing the three-dimensional sense of the inner lining, but also ensuring the stability of the side crown 4 during wearing and improving the overall wearing experience;

[0028] Furthermore, the cap core 1 is made of expanded polystyrene. Expanded polystyrene has excellent properties such as light weight, heat preservation, and sound insulation, making the cap core 1 both light and having good heat preservation performance. At the same time, it reduces the overall weight of the inner lining and improves the comfort during wearing;

[0029] Furthermore, the front crown 2, the rear crown 3, and the side crown 4 are made of soft and breathable polyester fiber. The softness of the polyester fiber ensures the comfort of each part of the inner lining, while the good breathability avoids the stuffy feeling during long-term wearing, enabling users to enjoy a pleasant wearing experience in different environments.

[0030] Furthermore, the first magic mother patch 5, the second magic mother patch 6, the third magic mother patch 7, the first magic son patch 8, the second magic son patch 9, and the third magic son patch 10 are all made of high-adhesion nylon material. Selecting high-adhesion nylon material as the material for the magic tape, its advantage lies in the wear-resistant, water-resistant, oil-resistant and other characteristics of the nylon material, so that these magic tapes can still maintain good adhesion performance after multiple uses, are not easy to fall off or fail, and can maintain adhesion after multiple disassembly and cleaning, thus extending the service life of the inner lining.

[0031] Working principle: During use, the user aligns the front crown 2 with the upper side of the inner wall of the cap core 1 to ensure accurate positioning. Subsequently, the six first magic son patches 8 sewn at the rear end of the front crown 2 are adhered to the six first magic mother patches 5 sewn on the upper side of the front end of the cap core 1. This design of the magic tape enables the front crown to be firmly fixed on the cap core while maintaining the flexibility of disassembly. The user aligns the rear crown 3 with the lower side of the inner wall of the cap core 1, and then uses the five second magic son patches 9 sewn on its rear end face to adhere to the five second magic mother patches 6 on the lower side of the front end of the cap core 1, thus completing the fixation of the rear crown. A set of two third magic mother patches 7 are sewn on both sides of the upper and lower sides of the front end of the cap core 1, and two sets of two third magic son patches 10 are sewn on the rear end face of the side crown 4. The user only needs to correspond and adhere the third magic son patches 10 at the rear end of the side crown 4 to the corresponding third magic mother patches 7 on the cap core 1 one by one to achieve the stable installation of the side crown 4. Through the connection method of the magic tape, the user can easily disassemble and install the front crown 2, the rear crown 3, and the side crown 4, which greatly facilitates the cleaning and maintenance of the inner lining.
