Description

Safety helmet with airbag {SAFETY HELMET WITH AIGBAG}

The present invention relates to a safety helmet equipped with an airbag, and more specifically, to a safety helmet equipped with an airbag that functions to protect the wearer's cervical spine and secure the airway in the event of an accident.

In the case of traffic accidents that occur while driving a motorcycle or bicycle, wearing a helmet can prevent damage to the head and brain to some extent, but existing helmets do not provide sufficient protection to the neck area. In addition, due to the weight and structural limitations of existing helmets, they are uncomfortable to wear and ventilation is poor, so they often receive negative reviews from users.

Generally, helmets are composed of exterior and interior materials. Exterior materials are mainly made of high-strength, shock-resistant synthetic resin materials, and interior materials are made of foamed resin that absorbs shock or other materials with good shock absorption. This structure can protect the head to some extent, but external shocks are easily transmitted internally, making complete protection difficult.

In particular, in helmets to date, the interior and exterior materials are in direct contact with each other and there is no separate space to absorb shock, so external shock can easily be transmitted internally in the event of a collision. Because of this, there is a risk that the impact will be transmitted directly not only to the head but also to the neck area.

Conventional technology is technical information that the inventor possessed for deriving the present invention or acquired in the process of deriving the present invention, and cannot necessarily be said to be known technology disclosed to the general public before filing the application for the present invention.

FIG. 5 is a block diagram illustrating components for controlling airbags included in the safety helmet 10 according to various embodiments of the present disclosure.

Referring to FIG. 5 , the control unit 600 of the safety helmet 10 may include an impact detection sensor 610 and an airbag control module 630.

The impact detection sensor 610 and the posture sensor 620 of the control unit 600 can detect whether an impact to the safety helmet 10 has caused an accident. The airbag control module 630 responds to the occurrence of an accident detected by the impact detection sensor 610, and includes an internal active airbag 300, an external active airbag 400, and an airway securing airbag (500) connected to the impact detection sensor 610. ) can be controlled to activate one or more of the following.

In one embodiment, the impact detection sensor 610 that can be installed on the helmet includes an acceleration sensor, a gyroscope, and a pressure sensor, and these can detect the size or direction of a collision, rotational movement, pressure change, etc. The posture sensor 620 includes an acceleration sensor, a gyroscope, a magnetic sensor, etc., and these perform tilt and rotation movements of the wearer and direction determination using the Earth's magnetic field. These sensors can be installed in the internal active airbag 300, the external active airbag 400, and the airway securing airbag 500 to analyze data in a complex manner.

Whether an accident has occurred to a person wearing the safety helmet 10 can be determined by comprehensively analyzing data from these sensors.

For example, if acceleration above a certain threshold is detected by the acceleration sensor and rapid rotational movement is detected by the gyroscope, it is determined that an accident has occurred and the airbag is activated. If there is no or slight movement of the wearer even after a certain period of time, it is determined that the wearer is stationary and, if necessary, an airbag to secure the airway can be activated. With multiple sensors linked in this way, accident detection and airbag activation can be performed more accurately.

The impact detection sensor 610 and the posture sensor 620 may be installed in each of one or more internal active airbags 300, external active airbags 400, and airway security airbags 500. In this embodiment, a plurality of sensors included in the impact sensor 610 and the posture sensor 620 can be linked to determine whether an accident has occurred.

In an embodiment, the internal active airbag 300, the external active airbag 400, and the airway securing airbag 500 may include a gas generating device or a compressed air device to be activated in response to control by the airbag control module 630. there is. For example, the airbag control module 630 may check whether an accident has occurred based on the detection results of one or more of the impact detection sensor 610 and the posture sensor 620. When it is determined whether an accident has occurred, the airbag control module 630 may transmit a signal that causes the activation of the internal active airbag 300, the external active airbag 400, and the airway securing airbag 500.

In one embodiment, the gas generating device may be an inflator that includes an ignition circuit, gunpowder, and a gas generating agent. When the gas generating device receives an activation signal from the airbag control module 630, the ignition circuit causes electric ignition in the ignition agent, and at that moment, the gunpowder is detonated to generate hot heat. Afterwards, the hot heat burns the gas generating agent to generate nitrogen gas, and the nitrogen gas can be delivered to each airbag to inflate it.

Compressed air devices can be operated by opening and closing valves using electromagnets (solenoids). Compressed gas is sealed inside a gas container, and the container may be equipped with a valve that is opened and closed by an electromagnet. Each airbag is connected to the end of the valve, so when the inflator opens the valve by driving an electromagnet under the control of the airbag control module 630, the compressed gas inside the gas container may be discharged to the airbag and inflate it. there is.

Here, the gas for airbag inflation is not limited and can be applied in various ways depending on the experiment and process conditions, and the structure of the inflator described above can also be applied individually or in combination of gunpowder ignition and electromagnet methods.

Meanwhile, in one embodiment, the internal active airbag 300 may be activated in response to an impact detected by the impact detection sensor 610 and then controlled to be deactivated after a certain period of time. For example, Figure 4 shows a state in which only the inner active airbag 300 is deactivated after the inner active airbag 300 and the outer active airbag 400 are activated.

Through this, the wearer of the safety helmet 10 can be relieved from the pressure felt by the expansion of the internal active airbag 300 inside the safety helmet 10 after an accident occurs.

In one embodiment, the external active airbag 400 may be configured to remain activated after being activated in response to an impact detected by a crash sensor. This is because the activated external airbag 400 allows the wearer to maintain the correct posture even after an accident.

Meanwhile, the airway securing airbag 500 may function to be activated after the impact detection sensor 610 detects an impact and again after detecting the wearer's stationary state. This is because the airway must be secured while the wearer is stationary.

For example, after an accident is identified based on the detection values of one or more of the impact detection sensor 610 and the posture sensor 620, the impact detection sensor 610 or the posture sensor 620 detects the user's stationary state. can do.

In one embodiment, the impact sensor 610 and the posture sensor 620 may be configured to detect the user's stationary state after a certain period of time (e.g., 10 seconds later) after the occurrence of an accident is identified. . Meanwhile, in the present disclosure, 'stationary state' may mean a state in which the wearer shows no movement or only slight movement. This condition can be measured through the posture sensor 620 or another motion detection sensor. In particular, the stationary state can be defined as when the wearer's speed, acceleration, change in posture, etc. falls below a certain threshold.

This stationary state is important in situations where the wearer no longer moves after a collision or accident, or when movement is greatly reduced and airway protection is required. For example, when a stationary state is detected, the airway securing airbag 500 is activated to secure the wearer's airway.

According to one embodiment, the impact sensor 610 and the posture sensor 620 may be set to determine the wearer's stationary state after a certain period of time, for example, 10 seconds, has passed after an accident is identified. This is to more accurately determine whether a situation in which securing an airway is actually necessary, as the wearer can temporarily move after an accident.

Physical Damage: The neck tilting motion may cause injury to the wearer's neck or spine. In particular, in an accident situation, if other parts of the neck are already injured, there is a possibility of worsening the situation.

As described above, the present invention is provided with an airbag activated from the inside of the helmet to protect the wearer's head, an airbag activated from the outside to protect the cervical spine, and an airway securing airbag that operates to secure the wearer's airway after an accident occurs. Thus, it provides effective protection and airway protection for not only the head but also the neck area.
