Description

Technical Field

[0001] This utility model belongs to the field of flight equipment technology and relates to a head six-airbag tactile presentation device. Background Technology

[0002] Spatial disorientation during flight refers to various illusions caused by a pilot's loss of proper perception of the aircraft and themselves. It primarily manifests as the inability to discern the aircraft's tilt direction and angle, which can seriously impact flight safety and has a high incidence rate. Statistics show that approximately 70% of pilots have experienced spatial disorientation.

[0003] Currently, traditional solutions include flight illusion simulators, which use six-degree-of-freedom motion platforms and virtual reality technologies to simulate flight illusions such as vestibular and visual illusions, allowing pilots to experience and learn how to deal with them in advance. However, since these methods are still at the experiential level, they lack reminders for pilots during flight training. As a result, when pilots encounter flight illusions, they still need to make judgments through sight and sound before they can spatially orient themselves. This not only increases the time required for pilots to spatially orient themselves but also reduces the accuracy of their spatial orientation. Utility Model Content

[0004] The purpose of this invention is to provide a six-airbag head tactile presentation device that can assist pilots in spatial orientation through real-time reminders, thereby reducing the time required for spatial orientation and improving the accuracy of spatial orientation.

[0005] To achieve the above objectives, the technical solution provided by this utility model is as follows: A six-airbag tactile presentation device for the head, including a head-mounted component, and further comprising: Six airbags are located inside the headgear, specifically at the forehead, back of the head, top of the headgear, chin, left side, and right side of the pilot's head. Flight angle detection component, used to detect the attitude angle of the head-mounted device in three-dimensional space in real time; Pressure detection components are installed inside each of the six airbags to detect the pressure values ​​inside each of the six airbags. The pressure regulating component is connected to each of the six airbags and is used to regulate the pressure inside each of the six airbags so that the corresponding airbags inflate and contract. The control component is electrically connected to the flight angle detection component, pressure detection component, and pressure adjustment component, respectively. It is used to receive the detected attitude angle and the pressure value inside each airbag in real time, determine the flight attitude based on the attitude angle, and control the pressure adjustment component to adjust the pressure inside the corresponding airbag to reach the preset pressure value, so that the airbag inflates and applies pressure to the position corresponding to the pilot's head to remind him of the flight attitude.

[0006] The features of this utility model also include: The flight angle detection component includes: A three-dimensional angle sensor is installed on the head-mounted device. The three-dimensional angle sensor is electrically connected to the control component and is used to detect the attitude angles of the head-mounted device in real time, including pitch angle, roll angle and yaw angle.

[0007] The pressure detection component includes: Six pressure sensors are installed inside the six airbags, and each of the six pressure sensors is electrically connected to the control components.

[0008] Each of the pressure sensors is a piezoresistive pressure sensor.

[0009] The pressure regulating component includes: Six micro pumps correspond one-to-one with six airbags. Each micro pump is electrically connected to the control unit, and the outlet of each micro pump is connected to the inlet of the corresponding airbag.

[0010] The pressure regulating component includes: Three micro-pumps are mounted on the head-mounted device and are electrically connected to the control assembly. The outlet of each micro-pump is connected to the inlet of two of the airbags via solenoid valves.

[0011] Each of the micro pumps is a MAC20A-01 micro piezoelectric pump.

[0012] Each airbag is made of thermoplastic polyurethane elastomer.

[0013] The head-mounted six-airbag tactile presentation device of this utility model has the following advantages: This invention uses a control component to receive and detect the attitude angle and the pressure value inside each airbag in real time. Based on the attitude angle, the flight attitude is determined, and the pressure adjustment component is used to adjust the pressure inside the corresponding airbag to a preset pressure value. This causes the airbag to inflate and apply pressure to the position corresponding to the pilot's head to remind them of the flight attitude. By using tactile stimulation, this invention assists the pilot in spatial orientation, overcoming the limitations of relying solely on visual and auditory judgment under complex flight conditions, which can easily lead to flight illusions. This reduces the time required for the pilot to spatially orient themselves and improves the accuracy of their spatial orientation. Attached Figure Description

In the description of the embodiments of this utility model, unless otherwise stated, " / " indicates "or," for example, A / B can mean A or B. "And / or" in the text is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A alone, A and B simultaneously, and B alone. Furthermore, in the description of the embodiments of this utility model, "multiple" refers to two or more. The terms "first" and "second" are used for descriptive purposes only and should not be construed as implying or suggesting relative importance or implicitly indicating the number of indicated technical features. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include one or more of that feature.

[0019] like Figure 1 , Figure 2As shown, this utility model provides a six-airbag tactile presentation device for the head, including a head-wearing component 1, six airbags 2, a flight angle detection component, a pressure detection component, a pressure adjustment component, and a control component. The six airbags 2 are disposed inside the head-wearing component 1, and are respectively located on the forehead, back of the head, top, jaw, left side, and right side of the head-wearing component 1 near the pilot's head. The pressure detection components are disposed inside the six airbags 2. The flight angle detection component is used to detect the attitude angle of the head-wearing component 1 in three-dimensional space in real time. The pressure detection component is used to detect the pressure value inside each of the six airbags 2. The pressure adjustment component is connected to each of the six airbags 2 and is used to adjust the pressure of each of the six airbags 2. The pressure inside airbag 2 causes the corresponding airbag 2 to inflate and contract. The control component is electrically connected to the pressure detection component and the pressure adjustment component. The control component is used to receive the detected attitude angle and the pressure value inside each airbag 2 in real time. Based on the attitude angle, the flight attitude is determined, and based on the flight attitude, the pressure adjustment component is controlled to adjust the pressure inside the corresponding airbag 2 to reach the preset pressure value. This causes the airbag 2 to inflate and apply pressure to the position corresponding to the pilot's head to remind them of the flight attitude. In this way, the pilot is assisted in spatial orientation through tactile stimulation, which makes up for the limitation that flight illusions can easily occur when relying solely on visual and auditory judgment under complex flight conditions. This reduces the time required for the pilot to spatially orient themselves and improves the accuracy of the pilot's spatial orientation.

[0020] like Figure 2 As shown, the flight angle detection component includes a three-dimensional angle sensor, which is mounted on the head-mounted device 1. The three-dimensional angle sensor is electrically connected to the control component and is used to detect the attitude angles of the head-mounted device 1 in real time, including pitch angle, roll angle and yaw angle.

[0021] like Figure 2 As shown, the pressure detection assembly includes six pressure sensors, which are respectively installed inside the six airbags 2. The six pressure sensors are electrically connected to the control assembly. Each pressure sensor is a piezoresistive pressure sensor, specifically model AGR09.

[0022] like Figure 2 As shown, this is one embodiment of the pressure regulating component in this utility model.

[0023] The pressure regulating component includes three micro pumps 3, which are mounted on the head-wearing device 1. The three micro pumps 3 are electrically connected to the control component, and the outlet of each micro pump 3 is connected to the inlet of two of the airbags 2 via solenoid valves 6.

[0024] like Figure 3 As shown, this is another embodiment of the pressure regulating component in this utility model.

[0025] The pressure regulating assembly includes six micro pumps 3, which correspond one-to-one with six airbags 2. Each micro pump 3 is electrically connected to the control assembly, and the outlet of each micro pump 3 is connected to the inlet of the corresponding airbag 2.

[0026] Each airbag 2 is made of thermoplastic polyurethane elastomer.

[0027] Each of the micro pumps is a MAC20A-01 micro piezoelectric pump.

[0028] The control group includes a controller, which is electrically connected to each micro pump, each solenoid valve, pressure sensor and three-dimensional angle sensor. The controller is equipped with a DAC8552 chip.

[0029] Working principle: During training, the pilot wears the headgear 1, with the six airbags 2 contacting the pilot's forehead, back of the head, top of the head, chin, left side, and right side of the head respectively. Simultaneously, the pilot enters a six-degree-of-freedom motion platform for simulated training. A three-dimensional angle sensor detects the attitude angle of the headgear 1 in real time and feeds it back to the control component. The control component determines the flight attitude based on the detected attitude angles, i.e., forward, backward, upward, downward, left, right, lower left, and upper right flight. Six pressure sensors detect the pressure values ​​inside the six airbags 2 in real time and feed them back to the control component. When the control component determines forward flight based on the attitude angles, it activates the micro-pump 3 corresponding to the airbag 2 located on the pilot's forehead. The micro-pump 3 delivers gas into the corresponding airbag 2, causing it to inflate. When the control component receives a pressure value that reaches a preset threshold, it shuts down. The miniature pump 3 applies pressure to the pilot's forehead via an airbag 2, providing tactile stimulation to help the pilot quickly determine whether they are flying forward. When the control unit determines that the flight is upward or downward based on the attitude angle, it controls the airbag 2 located at the top of the pilot's head or the airbag 2 located at the lower jaw to inflate, providing tactile stimulation to help the pilot quickly determine whether they are flying upward or downward, avoiding the illusion of the sea surface and sky that the pilot may have difficulty judging when flying over the sea. When the control unit determines that the flight is to the left or right based on the attitude angle, it controls the airbag 2 located on the left or right side of the pilot's head to inflate. When the control unit determines that the flight is to the lower left or upper right based on the attitude angle, it controls the airbag 2 on the left and the airbag 2 located at the lower jaw to inflate, or the airbag 2 on the right and the airbag 2 located at the top to inflate, thus reminding the pilot of the current flight attitude through tactile stimulation.

[0030] The following are other advantages of the head-mounted six-airbag tactile presentation device of this utility model: This invention can be used not only in flight training but also in actual flight, making it widely applicable.
