Description

Technical Field

[0001] This utility model relates to the field of helmet technology, specifically to a motorcycle helmet. Background Technology

[0002] During motorcycle riding, the helmet is a crucial piece of equipment for ensuring the rider's head safety. Its function is not limited to protection; it also needs to consider practicality and comfort. The visor, as an important component of the helmet, can effectively block direct sunlight, rain, and dust and other debris stirred up during riding, providing the rider with a clear field of vision. Therefore, the rationality of the connection structure between the visor and the helmet body directly affects the helmet's performance and user experience.

[0003] Currently, motorcycle helmets on the market are mainly divided into two types based on the connection between the visor and the helmet body: fixed structure and hinged structure. While the hinged type offers some angle adjustment capability, its structure is relatively complex, typically requiring multiple components such as pivots and damping parts. This not only increases the overall weight and manufacturing cost of the helmet, but also makes the hinged parts prone to wear and loosening during long-term use, leading to decreased visor stability and even adjustment failure, making it difficult to meet the needs of long-term, high-frequency riding.

[0004] Fixed helmets have become the mainstream choice for most mid-to-low-end motorcycle helmets due to their relatively simple structure and lower manufacturing cost. However, in existing fixed helmets, the visor is usually directly fixed to the helmet body with bolts. This connection method has obvious drawbacks: First, the disassembly and assembly process requires special tools, which is cumbersome, especially when the visor is damaged and needs to be replaced, or when the user needs to remove the visor according to different riding scenarios (such as night riding without sun protection). Second, bolted connections are usually fixed at a single point or a few points. Over time, they are subject to external forces such as airflow impact and vibration during riding, which can easily cause the bolts to loosen, leading to a decrease in the stability of the connection between the visor and the helmet body, and even posing a safety hazard of the visor falling off.

[0005] In summary, the existing connection structure between the brim and the body of a motorcycle helmet is difficult to balance ease of assembly and disassembly with connection stability, and cannot fully meet users' needs for ease of use and reliability of the helmet. Therefore, there is an urgent need for a brim connection structure design that can solve the above problems. Utility Model Content

[0006] In view of the shortcomings of the prior art, this utility model provides a motorcycle helmet.

[0007] The technical solution adopted by this utility model is: a motorcycle helmet, including a helmet body and a brim, the brim including an upper piece and side pieces located on both sides of the upper piece, a connecting sleeve is provided on the inner side wall of the upper piece and the inner side wall of the side pieces, the end of the connecting sleeve is provided with a "I" shaped groove, and a limiting step is provided on the end of the connecting sleeve outside the "I" shaped groove. The helmet body has connecting concave surfaces on both sides that are adapted to the end shape of the side plates, and connecting holes for connecting and engaging with connecting sleeves are provided in the connecting concave surfaces and on the upper side wall of the helmet body. The connecting sleeves on the side plate and the connecting sleeves on the upper plate are arranged in a triangular pattern.

[0008] Furthermore, the helmet body has a positioning step on its upper side, and one side of the positioning step is provided with a positioning notch that matches the end of the upper piece.

[0009] Furthermore, one end of the upper piece has a downwardly concave elastic settling portion, the elastic settling portion is provided with a weight reduction port, and the connecting sleeve is disposed inside the elastic settling portion.

[0010] Furthermore, the upper piece is provided with symmetrical lightning-shaped decorative grooves on both sides.

[0011] Furthermore, the end of the side piece has an upper side surface, a left side surface, a lower side surface, and a right side surface, and the connecting concave surface has a limiting sidewall that corresponds to and fits into the upper side surface, the left side surface, the lower side surface, and the right side surface.

[0012] Furthermore, a "V" shaped groove is formed between the upper side surface and the upper piece.

[0013] Furthermore, the side plate is provided with a decorative concave surface and a heat dissipation window.

[0014] Furthermore, the helmet body below the brim is provided with heat dissipation openings.

[0015] Furthermore, the bottom of the side plate is provided with an insert, and the bottom wall of the connecting concave surface is provided with a socket for inserting the insert.

[0016] The beneficial effects of this utility model are: 1. Easy assembly and disassembly: No bolts or special tools are required; assembly is achieved simply by using a connecting sleeve and a insert: the insert is inserted into the socket, and the connecting sleeve is snapped into the connecting hole (utilizing the elasticity of the "I" shaped groove and the positioning step); disassembly is achieved by simply separating them in the reverse direction. Users can easily replace the brim or disassemble and assemble the helmet according to riding scenarios (such as nighttime or indoors), resulting in efficient operation and a superior experience.

[0017] 2. More stable connection: The connecting sleeve is triangularly distributed (utilizing the stability of a triangle), which can evenly disperse external forces such as airflow impact and vibration, and avoid loosening due to single-point stress; at the same time, the limiting step restricts the displacement of the connecting sleeve, and together with the insert and socket, a multi-point positioning connection structure is formed to ensure connection stability.

[0018] 3. Simple structure and low cost: No complex components such as pivots and damping parts are required. Only the connecting sleeve and insert are integrated into the brim. The helmet body has corresponding holes / openings. The structure is compact and easy to mass-produce, effectively controlling costs. The "I" groove design takes into account both elasticity (easy to disassemble and assemble) and strength (resistance to external impact), balancing convenience and durability, and enhancing practical value.

[0019] In addition to the objectives, features and advantages described above, this utility model has other objectives, features and advantages.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] It should be noted that if the embodiments of this utility model involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicators will also change accordingly.

[0029] This utility model provides a motorcycle helmet.

[0030] In this embodiment, refer to Figure 1-5 The motorcycle helmet includes a helmet body 1 and a brim 2. The brim 2 includes an upper piece 3 and side pieces 25 located on both sides of the upper piece. Connecting sleeves 4 are provided on the inner sidewall of the upper piece 3 and the inner sidewall of the side pieces. A "I"-shaped groove 5 is provided at the end of the connecting sleeve 4. A limiting step 6 is provided on the end of the connecting sleeve outside the "I"-shaped groove 5. The helmet body has connecting concave surfaces 8 on both sides that are adapted to the end shape of the side plates. Connecting holes 9 for connecting and engaging with connecting sleeves are provided in the connecting concave surfaces 8 and on the upper side wall of the helmet body. The connecting sleeves on the side plate and the connecting sleeves on the upper plate are arranged in a triangular pattern.

[0031] In the above technical solution, the brim is divided into an upper piece and two side pieces. The shape of the end of the side piece is precisely matched with the connecting concave surface on both sides of the helmet body to ensure that the brim fits and is positioned in a close manner with the body, avoids misalignment during assembly, and improves connection stability. Multidirectional fixation is achieved through "connecting sleeve + insert". The connecting sleeve between the upper piece and the inner wall of the side piece uses the elastic deformation of the "I" groove at the end to snap into the connecting hole of the helmet body. The axial displacement of the connecting sleeve is then limited by the limiting step to prevent it from falling off. The insert at the bottom of the side piece is inserted into the socket of the bottom wall of the connecting concave surface to further enhance the lateral positioning. The side panel connecting sleeve and the upper panel connecting sleeve are arranged in a triangle. By utilizing the non-deformable structural characteristics of the triangle, the force on the brim is evenly distributed to the three connection points, thereby improving the overall connection stability.

[0032] The entire connection structure requires no bolts, making it easy to assemble and disassemble, reducing assembly difficulty, and reducing assembly time and improving production efficiency during mass production.

[0033] Specifically, the helmet body has a positioning step 11 on its upper side, and a positioning notch 12 adapted to the end of the upper piece is provided on one side of the positioning step 11.

[0034] In this embodiment, the fitting design of the positioning notch and the end of the upper piece is specifically designed to control the assembly deviation of the brim within 0.5mm, improving assembly accuracy and serving a positioning function. Furthermore, the positioning step bears the longitudinal force of the brim, reducing the load on the connecting sleeve, extending the service life of the connection structure, and reducing the probability of loosening of the connecting sleeve under long-term vibration.

[0035] Specifically, one end of the upper piece has a downwardly concave elastic settling portion 13, the elastic settling portion 13 is provided with a weight reduction port 14, and the connecting sleeve is provided inside the elastic settling portion.

[0036] In this embodiment, the downward concave elastic sinking part at one end of the upper piece has a weight-reducing opening on the elastic sinking part, which reduces the amount of brim material without affecting the structural strength, while forming an airflow channel to assist in heat dissipation and improve riding comfort in summer.

[0037] Specifically, the upper piece has symmetrically arranged lightning-shaped decorative grooves 15 on both sides.

[0038] In this embodiment, lightning-shaped decorative grooves are symmetrically arranged on both sides of the upper piece. The area of ​​the grooves is smaller than the area of ​​the entire upper piece, which not only does not damage the structural strength of the upper piece, but also enhances visual recognition through the unique lightning shape. At the same time, the grooves can guide airflow along both sides of the brim, reducing airflow resistance.

[0039] Specifically, the end of the side piece has an upper side surface 16, a left side surface 17, a lower side surface 18, and a right side surface 19, and the connecting concave surface has a limiting sidewall 20 that corresponds to and fits into the upper side surface, the left side surface, the lower side surface, and the right side surface.

[0040] In this embodiment, the side plate has four sides: top, left, bottom, and right. The limiting sidewall of the helmet body connecting concave surface fits into these four sides one by one, forming an all-round wrap-around positioning, which restricts the displacement of the side plate in six directions: up and down, left and right, and front and back, thereby improving the connection stability.

[0041] Specifically, a "V" shaped groove 21 is formed between the upper side and the upper piece.

[0042] In this embodiment, a "V" shaped groove is formed between the upper side of the side panel and the upper panel, with the groove opening facing the rear of the helmet (the person's face is facing forward). The V-shaped structure reduces the amount of material used, achieving local weight reduction. On the other hand, it also serves a decorative purpose, highlighting personalized design and product recognition.

[0043] Specifically, the side plate is provided with a decorative concave surface 22 and a heat dissipation window 23.

[0044] In this embodiment, by providing decorative concave surfaces and heat dissipation windows, the product's lightweight design and heat dissipation effect are improved. Specifically, the helmet body below the brim is provided with a heat dissipation opening 24.

[0045] In this embodiment, the heat dissipation effect is further improved by setting heat dissipation openings.

[0046] Specifically, the bottom of the side plate is also provided with an insert 7, and the bottom wall of the connecting concave surface is provided with a socket 10 for inserting the insert.

[0047] In this embodiment, the connection stability between the brim and the helmet body is further improved by adding the insert 7 and the socket 10. Attention all technical personnel: Although this utility model has been described according to the specific embodiments above, the concept of this utility model is not limited to this utility model. Any modification that utilizes the concept of this utility model will be included within the scope of protection of this patent right.
