[0002] Cycling helmets are the most solid protective barrier for life during cycling. Falling during cycling can cause great damage to the head. Even if the rider is riding at a lower speed along a bicycle path with a smooth slope, safety issues cannot be ignored. Cycling helmets can effectively protect the head when falling and reduce the damage to the head when hitting.

[0003] In the prior art, the Chinese utility model with announcement number: CN216315854U discloses a cycling helmet with a ventilation structure, which relates to the technical field of cycling helmets, and aims to solve the problem that the air inside the helmet cannot be actively driven to circulate, and the ventilation and heat dissipation efficiency is slow, including a cycling helmet; the cycling helmet is composed of a protective structure, a ventilation structure, a containing device and a fixed structure; the protective structure is internally movably connected with the ventilation structure, and the ventilation structure is arranged between the protective structure and the containing device; the containing device includes a connecting rod, and the containing device is fixedly connected to the protective structure through the connecting rod; the fixed structure is movably connected to the bottom of the protective structure. The setting of the ventilation structure of the utility model, through the collection trough and the rotating part, can drive the rotating part and the fan blades to rotate by the wind while the user is riding, and at the same time, the fan blades can make the air inside the cycling helmet circulate quickly, thereby improving the heat dissipation effect of the cycling helmet;

[0004] Although the above technical solution improves the ventilation effect of the helmet, the functionality of the helmet is single and can only protect the rider's head. When an accident occurs during riding, the rider's neck is the most impacted, and the safety protection of the rider needs to be further improved. Therefore, we need to propose a cycling helmet with an airbag. Utility Model Content

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] See also Figure 1-7 The utility model provides a technical solution: a cycling helmet with a safety airbag, comprising a helmet body 1, wherein an extension portion 14 is arranged at the lower edge of one end of the helmet body 1, a mounting groove 15 is arranged on the outer side of the extension portion 14, an airbag compartment 4 is installed in the mounting groove 15, an air pump compartment 3 is installed above the airbag compartment 4, an air pump body 5 is arranged in the air pump compartment 3, a trigger device 6 is installed at the end of the air pump body 5, an airbag bag located in the airbag compartment 4 is installed on the trigger device 6, and the airbag compartment 4 is arranged in an arc columnar shape.

[0025] A head fixing frame 7 is clamped on the top of the inner cavity of the helmet body 1, and an isolation cavity is provided between the head fixing frame 7 and the helmet body 1. The isolation cavity prevents direct contact between the head and the helmet body 1, thereby facilitating buffering when a sudden collision occurs.

[0026] Two groups of restraints 8 are symmetrically arranged at the lower end of the head fixing frame 7. The lower ends of the two groups of restraints 8 are respectively installed with locking blocks 9 and locking sleeves 10. The locking blocks 9 are slidably engaged in the locking sleeves 10. The locking blocks 9 are conveniently inserted into the locking sleeves 10 through the restraints 8, so that the head fixing frame 7 is suitable for riders with different head circumferences.

[0027] A safety indicator light 11 is installed on one side of the lock sleeve 10, and the safety indicator light 11 is electrically connected to the trigger device 6. When the rider wears the helmet body 1 but does not insert the lock block 9 into the lock sleeve 10, the safety indicator light 11 lights up to warn the rider, reminding the rider to wear the helmet body 1 correctly.

[0028] A wind-breaking brim 2 is fixedly connected to the upper edge of the other end of the helmet body 1. The outer surface of the helmet body 1 is provided with multiple groups of reinforcement parts 12. The wind-breaking brim 2 facilitates breaking wind resistance when riding, and can also block rain to ensure that the riding field of vision is not affected.

[0029] A plurality of groups of air inlet holes 13 are provided at one end of the outer surface of the helmet body 1, and a plurality of groups of air outlet holes 17 are provided at the other end of the outer surface of the helmet body 1. The plurality of groups of air inlet holes 13 and the plurality of groups of air outlet holes 17 are all connected with the inner cavity of the helmet body 1. The air inlet holes 13 and the air outlet holes 17 improve the ventilation effect of the helmet body 1 during riding, thereby improving the riding experience of the rider.

[0030] A plurality of connection holes 16 communicating with the inner cavity of the helmet body 1 are provided at the bottom of the mounting groove 15. A buffer sleeve is provided between the helmet body 1 and the head fixing frame 7. The buffer sleeve (not shown in the figure) inside the helmet body 1 can buffer the head, further reducing the impact of emergencies on the rider.

[0031] During use, when the rider's body center of gravity changes, the six-axis gyroscope, six-axis gravity sensing accelerometer and MCU installed on the vehicle monitor the center of gravity of the vehicle, and transmit a signal to the trigger device 6 after monitoring the gravity change, so that the trigger device 6 controls the air pump body 5 to quickly inflate the airbag in the airbag chamber 4 (the filling gas is inert gas helium), so that the airbag is deployed to protect the rider's neck and head, avoiding sudden situations from affecting the rider's safety.

[0032] like Figure 5-7As shown, the trigger device in the technical solution is an existing technology. When the six-axis gyroscope (when an object undergoes linear acceleration or rotation, the gyroscope and the accelerometer will be subjected to corresponding forces, the gyroscope measures the rotational angular velocity of the object by detecting tiny vibrations, and the accelerometer measures the linear motion acceleration of the object by detecting gravity acceleration and non-gravity acceleration) and the six-axis gravity sensing accelerometer (gravity sensing up and down, left and right, front and back translation, the six-axis sensing can not only sense up and down, left and right, front and back translation, but also can turn left and right, up and down, front and back, and has stronger spatial capture ability) detect the inertia and center of gravity changes of the helmet, and then the MCU calculates and issues instructions, thereby controlling the trigger device to open the air outlet of the air pump body to achieve rapid expansion of the airbag;

[0033] The trigger device 6 in the airbag compartment 4 is charged with electric energy through the charging part, and the electric quantity is detected in real time. After the lock block 9 is inserted into the lock sleeve 10, the safety indicator light 11 lights up, thereby ensuring the safety of the rider. At the same time, the processor calculates the change of gravity acceleration of the rider, and then starts the trigger device 6 to drive the air pump body 5 when the gravity of the rider changes, so that the gas fills the airbag within 0.1 seconds, thereby realizing rapid protection of the rider's head and neck.

[0034] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
