[0025] To make the above-mentioned objects, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0026] It should be noted that when an element is referred to as being "fixed to" another element, it can be directly attached to the other element or there may be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or there may be an intervening element. When the number of elements is referred to as "multiple," it can be any number of two or more. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementation.

[0027] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0028] The present invention will now be described in detail with reference to the embodiments shown in the accompanying drawings:

[0029] like Figures 1-4 As shown, this embodiment provides a helmet airbag, including an airbag cover 1 and a sealing plate 2. The airbag cover 1 and the sealing plate 2 are sealed and fixedly connected. The airbag cover 1 covers the sealing plate 2 to form an internal air cavity. After the sealing plate 2 is closed and sealed, there is gas inside the airbag, forming an air cavity that can buffer impacts. An integrally formed partition 4 is provided inside the airbag cover 1. The partition 4 is arranged inside the airbag cover 1 and divides the air cavity into air channels 5. The partition 4 can provide support and prevent the airbag cover 1 from shifting too much to the left or right when it is hit, thus failing to provide protection. With the presence of the partition 4, even if a part of the airbag is subjected to greater pressure, the gas flow rate in the cavity will not be too fast. The gas in the airbag still needs to flow along the air channels 5 formed by the partition 4. Therefore, preventing the airbag from deforming too quickly cannot effectively protect the user's head.

[0030] Further explanation includes Velcro 3, which is fixedly connected to the sealing plate 2. Velcro 3 is used to adhere to the Velcro 3 that is fixedly installed inside the helmet. Velcro 3 includes a rough side and a hook side. In this utility model, Velcro 3 and the Velcro 3 fixed to the helmet can be attached using the rough side and the hook side respectively. These are common knowledge and will not be elaborated further.

[0031] In this embodiment, both sides of the partition 4 abut against the inner bottom wall of the airbag cover 1 and the inner side wall of the sealing plate 2, respectively.

[0032] There is at least one partition 4. Preferably, the partition 4 has a V-shaped structure, and there are two partitions 4, such as... Figure 2 The pair of partitions 4 shown are arranged opposite each other on the horizontal plane of the bottom wall inside the airbag 1, rotated 180 degrees. One partition 4 is positioned with the other partition 4 rotated 180 degrees from its position inside the airbag 1. The pair of partitions 4 are arranged at intervals, and each partition 4 is provided with a buffer groove area 7. Both partitions 4 have buffer groove areas 7, thus dividing the middle part of the airway 5 into... Figure 2 The Z-shaped shape shown will prevent excessive gas flow regardless of whether the force is greater at the front end or the rear end of airway 5.

[0033] When impacted, the airbag will shift left and right or forward and backward due to the pressure from the head. A certain degree of shift can buffer the pressure. The baffle 4 set in this invention can correct the shift and control the shift within a certain threshold to avoid excessive shift of the airbag and excessive gas flow in the airbag, which would cause the user's head to collide directly with the inner wall of the helmet. Therefore, this invention can significantly improve the protective performance of the helmet.

[0034] When subjected to impact, airbags deform very quickly, and the head can easily hit the ground, thus failing to provide good protection.

[0035] The airbag shroud 1 has a certain height. During use, that is, after the rider puts on the helmet, the airbag shroud 1 will push the helmet up, meaning there is a certain gap between the helmet and the user's head to allow for ventilation and heat dissipation. In addition, typical cycling helmets have many openings, thus improving breathability while ensuring cushioning performance. Because this invention does not completely cover the user's head, in specific use... Figure 3 As shown, one part of the airbag is fixed inside the top of the helmet, while the other two are fixed to the side walls of the helmet. The specific mounting points can also protect the rider's head. The outer wall of the airbag cover 1 is provided with interval patterns 6, which can further improve the air permeability of the contact surface between the airbag and the user's head.

[0036] like Figure 3As shown, the slightly longer air bag in the middle is composed of two air bag covers 1, and the internal structure of the single air bag cover 1 is the same.

[0037] The technical features of the above-mentioned embodiments can be combined in any manner. In order to make the description simple, all possible combinations of the technical features in the above-mentioned embodiments are not described, however, as long as the combinations of the technical features do not contradict, they should be considered as the scope of the present disclosure. For those skilled in the art, without departing from the concept of the present disclosure, some modifications and improvements can be made, which are all within the protection scope of the present disclosure. Therefore, the protection scope of the present patent should be subject to the appended claims.
