Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of protective devices, and in particular to a neck protection device, a control method thereof, and a computer-readable storage medium. Background Art
[0002] In the related art, high-speed moving vehicles will generate relatively high acceleration. If there is no corresponding protection device for the occupant's neck, it is very easy to cause neck injuries. The neck is rich in spinal nerve centers and blood vessels and is very important for the human body. Moreover, the high-acceleration working conditions are relatively complex, and it is impossible to ensure that the airbags or protection devices inside the vehicle can protect the neck in all directions. For example, the pilot's working conditions:
[0003] 1. Ejection condition
[0004] The load curve of the pilot during ejection is as Figure 13 shown. It can be seen that the load curve of this condition is divided into four stages: a static stage, a growth stage, a stable stage, and a decay stage. 0ms - 20ms is the static stage, and the ejection device is energized during this stage; 20ms - 80ms is the growth stage, and the ejection device continuously increases the impact force during this stage, and the acceleration load continues to rise; 80ms - 100ms is the stable stage, and the ejection device provides stable power during this stage, and the acceleration remains basically unchanged; 100ms - 160ms is the decay stage, during which the ejection device completes the ejection action, the power begins to decay, and the acceleration load begins to decrease.
[0005] 2. Arrested landing condition
[0006] The acceleration curve of a carrier-based aircraft with a weight of 50,000 lb during arrested landing is as Figure 14 shown. The arrested landing process takes about 2700ms and can be divided into three stages, namely: a growth stage, a steady stage, and a decay stage. 0ms - 500ms is the growth stage, during which the fighter plane comes into contact with the carrier-based arresting cable, and the acceleration load increases linearly; 500ms - 1700ms is the steady stage, during which the tension of the arresting cable and the reaction force of the fighter plane are relatively fixed, and the acceleration load remains relatively constant, and the fighter plane begins to decelerate. 1700ms - 2700ms is the decay stage, and after the arresting cable completes the arresting task, the tension gradually decreases, the acceleration load gradually decreases, and the deceleration of the fighter plane is completed.
[0007] The neck NIC injury criterion is used to evaluate the relationship between the degree of spinal nerve injury and the pressure gradient, and the NIC value is defined as follows:
[0008] NIC = 0.2a rel +V rel 2
[0009] where arel Defined as the acceleration of the centroid of the head relative to the first thoracic vertebra (T1) in the first direction, V rel Defined as the velocity of the centroid of the head relative to T1 in the first direction, 0.2 is the length coefficient, with the unit of m. The absolute value of the threshold of NIC is 15m 2 / s 2 The characteristics of these classical high-G working conditions are all to generate relatively high accelerations in a short period of time, which will cause relatively large displacements and accelerations of the head relative to the neck. These working conditions are extremely likely to cause damage to the neck. Therefore, there is an urgent need for a protection device that can comprehensively protect the necks of occupants (such as pilots). SUMMARY OF THE INVENTION

[0046] Embodiments of the present invention will be described in detail below. Examples of the embodiments are shown in the accompanying drawings, where the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the accompanying drawings are exemplary and are only used to explain the present invention and should not be construed as a limitation of the present invention.
[0047] Reference is made below to Figures 1 - 12 describe a neck protection device 100 and its control method and computer-readable storage medium according to an embodiment of the present invention.
[0048] As Figure 1 shown, a neck protection device 100 according to an embodiment of the present invention includes: a protection airbag 1, a gas delivery member 2, a pipeline 3, a controller 4, and an acceleration sensor 5. The protection airbag 1 can be sleeved outside the neck. The pipeline 3 is connected between the gas delivery member 2 and the protection airbag 1. The controller 4 is communicatively connected to both the acceleration sensor 5 and the gas delivery member 2. The controller 4 is configured to control the start and stop of the gas delivery member 2 according to the detection information of the acceleration sensor 5.
[0049] Among them, the protection airbag 1 can be configured in a "swim ring" shape. The protection airbag 1 can be sleeved outside the human neck. The protection airbag 1 can be filled with gas and the gas in the protection airbag 1 can be discharged. When the protection airbag 1 is filled with an appropriate amount of gas, the protection airbag 1 can have a supporting force on the neck, and the protection airbag 1 will deform and contract when subjected to the pressure of the user's neck to absorb the pressure and reduce the amplitude of neck shaking, so as to effectively protect the user's neck.
[0050] As some embodiments of the present invention, the neck protection device 100 can be applied to a pilot flying an aircraft. When the pilot wears the protection airbag 1 and is in the process of high-acceleration flight, the protection airbag 1 can reduce the risk of neck injury when the pilot constantly turns his head to observe the direction, and the protection airbag 1 can reduce injuries such as whiplash injury caused by high-speed impact to the pilot's neck.
[0051] As some embodiments of the present invention, a pilot flying an aircraft will experience a variety of different working conditions. For example: the ejection working condition, the load curve of the pilot during ejection is as Figure 13 shown. It can be seen that the load curve of this working condition is divided into four stages: a static stage, a growth stage, a stable stage, and a decay stage. The period from 0 ms to 20 ms is the static stage, and the ejection device is energized during this stage. The period from 20 ms to 80 ms is the growth stage, and the ejection device continuously increases the impact force during this stage, and the acceleration load continues to rise. The period from 80 ms to 100 ms is the stable stage, and the ejection device provides stable power during this stage, and the acceleration remains basically unchanged. The period from 100 ms to 160 ms is the decay stage. During this period, the ejection device completes the ejection action and the power begins to decay, and the acceleration load begins to decline.
[0052] Alternatively, a pilot flying an aircraft may also experience the arrested landing condition. The acceleration curve of an arrested landing of a carrier-based aircraft with a weight of 50,000 lb is as shown in Figure 14 . The arrested landing process takes about 2,700 ms in total and can be divided into three stages, namely: the increasing stage, the steady stage, and the decaying stage. The period from 0 ms to 500 ms is the increasing stage. In this stage, the fighter jet comes into contact with the carrier-based arresting cable, and the acceleration load increases linearly. The period from 500 ms to 1,700 ms is the steady stage. In this stage, the tension of the arresting cable and the reaction force of the fighter jet are relatively fixed, the acceleration load remains relatively constant, and the fighter jet starts to decelerate. The period from 1,700 ms to 2,700 ms is the decaying stage. After the arresting cable completes the arresting task, the tension gradually decreases, the acceleration load gradually decreases, and the deceleration of the fighter jet is completed.
[0053] The neck NIC injury criterion can be used to evaluate the relationship between the degree of spinal nerve injury and the pressure gradient, and the NIC value is defined as follows:
[0054] NIC = 0.2a rel +V rel 2 where a rel is defined as the acceleration of the head centroid relative to the first thoracic vertebra (T1) in the first direction, and V rel is defined as the velocity of the head centroid relative to T1 in the first direction. 0.2 is the length coefficient with the unit of m. The absolute value of the threshold of NIC is 15 m 2 / s 2 .
[0055] The characteristics of the above high-acceleration conditions are all to generate a relatively high acceleration in a short time, which will cause a relatively large displacement and acceleration of the pilot's head relative to the neck. These conditions are extremely likely to cause damage to the neck. Using the neck protection device 100 proposed by the present invention can effectively protect the neck safety of the pilot.
[0056] As some embodiments of the present invention, the neck protection device 100 can be applied to users driving vehicles. When the user wears the airbag 1 and the vehicle driven by the user is rear-ended, the airbag 1 can support the neck to reduce the movement amplitude of the neck's forward and backward tilting caused by inertia, thereby reducing the injury to the user's neck caused by whiplash injury.
[0057] It should be emphasized that the application of the above neck protection device 100 to pilots flying aircraft and users driving vehicles is only an exemplary list, and does not mean that the neck protection device 100 proposed by the present invention is only limited to being applied to pilots flying aircraft and users driving vehicles.
[0058] The pipeline 3 is connected between the gas delivery member 2 and the airbag 1. When the gas in the airbag 1 is insufficient, the gas delivery member 2 can fill the airbag 1 with gas through the pipeline 3 to complete the inflation process. Moreover, the gas delivery member 2 can discharge the gas in the airbag 1 to the outside through the pipeline 3 to complete the exhaust process. It can be understood that both the inflation process and the exhaust process of the neck protection device 100 can be carried out multiple times to reasonably adjust the gas content in the airbag 1 to meet various usage requirements of the user, and the neck protection device 100 can be used multiple times.
[0059] The acceleration sensor 5 can detect the acceleration information of the neck protection device 100. The controller 4 is communicatively connected to both the acceleration sensor 5 and the gas delivery member 2. The acceleration sensor 5 can transmit the detected acceleration information to the controller 4 in the form of an acceleration signal (electrical signal). The controller 4 can receive and analyze the acceleration signal, and the controller 4 can obtain the acceleration information of the neck protection device 100 based on the acceleration signal. The controller 4 can compare the magnitude relationship between the acceleration information and the preset acceleration to control the start and stop of the gas delivery member 2 according to the magnitude relationship between the acceleration information and the preset acceleration.
[0060] Specifically, if the acceleration information is greater than the preset acceleration, the controller 4 can control the gas delivery member 2 to inflate the airbag 1 to increase the supporting force of the airbag 1 on the neck for better buffering and protection of the neck. If the acceleration information is less than or equal to the preset acceleration, the controller 4 controls the gas delivery member 2 to exhaust the airbag 1 to reduce the supporting force of the airbag 1 on the neck and release the freedom of the pilot's neck, making it more convenient for the user to turn, tilt, or lower the head, etc., and facilitating the user to observe the surrounding environment. The acceleration sensor 5, the controller 4, and the gas delivery member 2 can all respond quickly to provide better protection for the user.
[0061] In the above embodiment, the controller 4 can control the start and stop of the gas delivery member 2 according to the detection information of the acceleration sensor 5 to inflate the airbag 1 or exhaust the airbag 1 to adjust the magnitude of the supporting force of the airbag 1 on the neck, so that the neck protection device 100 can buffer and protect the user's neck according to actual needs, reduce the risk of the user's neck injury, and can exhaust the airbag 1 in some cases to facilitate the user to move the neck. In addition, the neck protection device 100 can be automatically adjusted, with good usability and technological nature.
[0062] As some embodiments of the present invention, the controller 4 can be a single-chip microcomputer control system. The single-chip microcomputer control system has the advantages of small volume, low power consumption, and strong control ability, which can improve the reliability of the controller 4.
[0063] As some embodiments of the present invention, such asFigure 2 As shown in the figure, the designed airbag 1 can be modeled. The model of the airbag 1 can be established based on the LS-DYNA software. Use the Curve-circle function to draw a concentric circle with an inner diameter of 120 mm and an outer diameter of 240 mm according to the average neck circumference of the human body. Use the Mesh-Blank Mesher function to select the concentric circle and set the mesh size. The mesh size of this model is set to 5 mm to form the first patch of the airbag 1. Subsequently, use the Ele Tol-Transform function to translate the patch 1 mm along the radial direction and copy itself at the original position to form two airbag patch models. Use the Eege function to display the model edges, select the edges of the two patches, and use the Transform function to translate them 0.5 mm towards each other. After the edges coincide, use the Ele Tol-Duplicate Nodes function to find duplicate nodes, and select Merge Dup Nodes to merge the duplicate nodes of the two patches to complete the stitching of the two patches.
[0064] As Figure 3 shown, Figure 3 As shown in the figure, it is a schematic diagram of the folding method. Use the ABFold function to fold the airbag 1, and the folding method is Thin Flod, which is folded according to the right-hand rule.
[0065] As Figure 4 shown, Figure 4 As shown in the figure, it is the schematic diagram of the CV method principle. The most commonly used CV method for the airbag 1 is to conduct simulation. In this method, the airbag 1 is regarded as a control volume, and the volume of the control volume expands continuously with time. The heat capacity is set as a constant, and the gas in the control volume is assumed to be an ideal gas. The CV method describes the gas generated in the airbag 1 through two parameters, namely the mass flow rate and the temperature. The gas mass flow curve and the temperature curve are as Figure 5 and Figure 6 shown.
[0066] In the CV method, the control volume at each time step can be obtained through the Green integral, that is
[0067]
[0068] where i is the element number, is the average coordinate of the i-th element, nix is the cosine of the angle between the normal direction of the element surface and the X direction, Ai is the area of the i-th element, and N is the total number of elements.
[0069] The relationship between the pressure p2, the gas density ρ, and the specific internal energy e of the gas in the airbag 1 is:
[0070] p 2 =(γ - 1)ρe
[0071] Among them, γ is the specific heat ratio constant, γ = cp / cv, where cp is the specific heat capacity at constant pressure of the gas, cv is the specific heat capacity at constant volume of the gas, and p is the internal pressure of the airbag.
[0072] After derivation, the relational expression of the specific internal energy at adjacent time points is:
[0073]
[0074] Among them, i and i + 1 represent two adjacent time points before and after.
[0075] Perform a gas filling simulation on the airbag 1. The airbag 1 takes the initiation process of an automotive airbag in an ideal state as a reference, and factors such as the gas filling speed and durability of the airbag 1 are ignored. The translational degrees of freedom of the airbag 1 in the x and y directions and the rotational degrees of freedom about the x, y, and z axes are constrained. The model is in a 1G conventional gravity field, and the simulation time is set to 50 ms. The gas filling and deployment process of the airbag 1 is as Figures 7 - 10 shown.
[0076] After the gas has been basically filled, observe that the airbag 1 maintains its inflated shape, with a full form, and there is no situation where the airbag 1 becomes deflated due to insufficient gas filling mass or the airbag 1 ruptures due to excessive gas filling.
[0077] In some embodiments of the present invention, as Figure 1 shown, the neck protection device 100 further includes: a first one-way valve 6 and a second one-way valve 7. The pipeline 3 includes: a first pipeline 31 and a second pipeline 32. Both the first pipeline 31 and the second pipeline 32 are connected between the gas delivery member 2 and the airbag 1. The first one-way valve 6 is provided in the first pipeline 31 and is configured to conduct unidirectionally from the gas delivery member 2 to the airbag 1 direction. The second one-way valve 7 is provided in the second pipeline 32 and is configured to conduct unidirectionally from the airbag 1 direction to the gas delivery member 2.
[0078] Among them, both the first pipeline 31 and the second pipeline 32 can be connected between the gas delivery member 2 and the airbag 1. Both the first pipeline 31 and the second pipeline 32 allow gas to flow through. The first one-way valve 6 is provided on the first pipeline 31. The first one-way valve 6 can be configured as a mechanical valve. The first one-way valve 6 conducts unidirectionally from the gas delivery member 2 to the airbag 1 direction. That is to say, gas can flow from the gas delivery member 2 through the first one-way valve 6 to the airbag 1, but the gas in the airbag 1 cannot flow through the first one-way valve 6 from the airbag 1.
[0079] A second check valve 7 is provided on the second pipeline 32. The second check valve 7 can be configured as a mechanical valve. The second check valve 7 conducts unidirectionally from the direction of the airbag 1 to the gas delivery member 2. That is to say, the gas in the airbag 1 can flow from the airbag 1 to the gas delivery member 2 through the second check valve 7, but the gas cannot flow to the airbag 1 through the second check valve 7. In addition, the mechanical valve has a simple structure and high reliability. By configuring both the first check valve 6 and the second check valve 7 as mechanical valves, the service reliability of the first check valve 6 and the second check valve 7 can be improved, facilitating maintenance and management, and having a wide range of applications.
[0080] In the above embodiment, the airbag 1 can be inflated through the first check valve 6 and the first pipeline 31, and the airbag 1 can be exhausted through the second check valve 7 and the second pipeline 32, so that the inflation process and the exhaust process are both independent and do not interfere with each other, thereby improving the service reliability of the neck protection device 100.
[0081] As some embodiments of the present invention, both the first check valve 6 and the second check valve 7 can be configured as electrically controlled valves, and the controller 4 can control the opening or closing of the first check valve 6 and the second check valve 7. Specifically, when it is necessary to inflate the airbag 1, the controller 4 can control the gas delivery member 2 to work, and the controller 4 can control the first check valve 6 to open. The gas delivery member 2 can fill the airbag 1 with gas through the first pipeline 31. When the gas in the airbag 1 is sufficient, the controller 4 controls the gas delivery member 2 and the first check valve 6 to close, and the inflation process is completed. When it is necessary to exhaust the airbag 1, the controller 4 can control the gas delivery member 2 to work, and the controller 4 can control the second check valve 7 to open. The gas delivery member 2 can exhaust the gas from the airbag 1 through the second pipeline 32. When the gas content in the airbag 1 is appropriate, the controller 4 controls the gas delivery member 2 and the second check valve 7 to close, and the exhaust process is completed. By configuring both the first check valve 6 and the second check valve 7 as electrically controlled valves, the inflation process and the exhaust process can be precisely controlled, and the degree of automation of the neck protection device 100 can be improved.
[0082] In some embodiments of the present invention, as Figure 1 shown, there are two gas delivery members 2. The first pipeline 31 is connected between one of the gas delivery members 2 and the airbag 1, and the second pipeline 32 is connected between the other gas delivery member 2 and the airbag 1. Or, there is one gas delivery member 2, and both the first pipeline 31 and the second pipeline 32 are connected between the same gas delivery member 2 and the airbag 1.
[0083] Among them, in one embodiment, the number of gas delivery members 2 can be two, including a first gas delivery member 21 and a second gas delivery member 22. The first pipeline 31 can be connected between the first gas delivery member 21 and the protection airbag 1. The first gas delivery member 21 can be used to inflate the protection airbag 1. The second pipeline 32 can be connected between the second gas delivery member 22 and the protection airbag 1. The second gas delivery member 22 can be used to exhaust the protection airbag 1. By providing the first gas delivery member 21 and the second gas delivery member 22, the first gas delivery member 21 and the second gas delivery member 22 can each achieve the corresponding inflation function and exhaust function. The first gas delivery member 21 and the second gas delivery member 22 do not interfere with each other during operation, so as to improve the reliability of use of the gas delivery member 2 and facilitate maintenance and management.
[0084] Alternatively, in another embodiment, the number of gas delivery members 2 is one. The first pipeline 31 and the second pipeline 32 are both connected between the same gas delivery member 2 and the protection airbag 1. The gas delivery member 2 can have three working states, including an inflation state, an exhaust state, and a closed state. The gas delivery member 2 can be switched between the inflation state, the exhaust state, and the closed state. When the gas delivery member 2 is in the inflation state, it can inflate the protection airbag 1. When the gas delivery member 2 is in the exhaust state, it can exhaust the protection airbag 1. When the gas delivery member 2 is in the closed state, the gas delivery member 2 does not work, and the gas content in the protection airbag 1 remains unchanged. When it is necessary to inflate the protection airbag 1, the gas delivery member 2 can be switched from the closed state to the inflation state. When the inflation is completed, the gas delivery member 2 can be switched from the inflation state to the closed state. When it is necessary to exhaust the protection airbag 1, the gas delivery member 2 can be switched from the closed state to the exhaust state. When the exhaust is completed, the gas delivery member 2 can be switched from the exhaust state to the closed state. By only providing one gas delivery member 2, the inflation function and the exhaust function can be realized, and the number of components can be reduced, the cost can be saved, and the integration degree of the neck protection device 100 can be improved.
[0085] In some embodiments of the present invention, the neck protection device 100 further includes: a pressure sensor. The controller 4 is communicatively connected to the pressure sensor. The pressure sensor is used to detect the pressure information of the protection airbag 1. The controller 4 is used to obtain the pressure information of the protection airbag 1 and control the start and stop of the gas delivery member 2 according to the pressure information of the protection airbag 1.
[0086] Among them, the air pressure sensor can detect the air pressure information of the airbag 1. The air pressure sensor can be communicatively connected to the controller 4. The air pressure sensor can transmit the detected air pressure information of the airbag 1 to the controller 4 in the form of an air pressure signal (electrical signal form). The controller 4 can receive and parse the air pressure signal, and the controller 4 can obtain the air pressure information of the airbag 1 according to the air pressure signal. The controller 4 can compare the size relationship between the air pressure information of the airbag 1 and the preset air pressure value, and control the start and stop of the gas delivery member 2 according to the relationship between the air pressure information of the airbag 1 and the preset air pressure value.
[0087] The air pressure sensor can be used in cooperation with the acceleration sensor 5. Specifically, if the acceleration information detected by the acceleration sensor 5 is greater than the preset acceleration, and the air pressure value of the airbag 1 detected by the air pressure sensor is less than or equal to the preset air pressure value, the controller 4 controls the gas delivery member 2 to work to inflate the airbag 1. If the acceleration information detected by the acceleration sensor 5 is greater than the preset acceleration, and the air pressure value of the airbag 1 detected by the air pressure sensor is greater than the preset air pressure value, the controller 4 controls the gas delivery member 2 to stop inflating.
[0088] If the acceleration information detected by the acceleration sensor 5 is less than or equal to the preset acceleration, and the air pressure value of the airbag 1 detected by the air pressure sensor is greater than zero, the controller 4 controls the gas delivery member 2 to work to exhaust the airbag 1. If the acceleration information detected by the acceleration sensor 5 is less than or equal to the preset acceleration, and the air pressure value of the airbag 1 detected by the air pressure sensor is less than or equal to zero, the controller 4 controls the gas delivery member 2 to stop exhausting.
[0089] In the above embodiment, by setting the air pressure sensor, the controller 4 can control the start and stop of the gas delivery member 2 according to the air pressure information of the airbag 1 detected by the air pressure sensor, so as to accurately control the gas content in the airbag 1. The control process is reliable and can respond quickly, so that the airbag 1 can better protect the user's neck and improve the user's satisfaction.
[0090] In some embodiments of the present invention, the controller 4, the acceleration sensor 5, and the air pressure sensor are integrally arranged, and / or the material structure of the airbag 1 is nylon.
[0091] Among them, the controller 4, the acceleration sensor 5, and the air pressure sensor can be integrally arranged to reduce the space occupied by the controller 4, the acceleration sensor 5, and the air pressure sensor, and can improve the signal transmission efficiency, facilitate maintenance and management, and can improve the modularization and integration degree of the neck protection device 100.
[0092] The material of the protective airbag 1 can be nylon, which has good mechanical properties and has the advantages of high strength-to-weight ratio, high thermal stability, high chemical stability, high elasticity, low moisture content, low density, etc. For example, the protective airbag 1 can be made of nylon 6.6, nylon 6.6. In this way, the protective airbag 1 can lose less or even no gas during inflation and deployment, which can improve the structural strength of the protective airbag 1 and the reliability of the protective airbag 1. In addition, the protective airbag 1 can be made lighter, lower in cost, and has good practicality.
[0093] Figure 11 : is a flow chart of a control method of a neck protection device according to an embodiment of the present invention. The neck protection device of the above embodiment can implement the control method, such as Figure 1 As shown, the neck protection device includes: a protective airbag, a gas conveying component, a pipeline, a controller and an acceleration sensor. The protective airbag can be mounted on the outside of the neck. The pipeline is connected between the gas conveying component and the protective airbag. The controller is communicatively connected with the acceleration sensor and the gas conveying component. The controller is constructed to control the start and stop of the gas conveying component according to the detection information of the acceleration sensor.
[0094] Among them, the protective airbag can be constructed as a "swimming ring"-like structure, which can be mounted on the outside of the human neck. The protective airbag can be filled with gas and the gas in the protective airbag can be discharged. When the protective airbag is filled with an appropriate amount of gas, the protective airbag can provide support for the neck, and the protective airbag will deform and contract when subjected to pressure from the user's neck to absorb the pressure and reduce the amplitude of neck shaking to effectively protect the user's neck.
[0095] As some embodiments of the present invention, the neck protection device can be applied to pilots flying aircraft. When the pilot wears a protective airbag and is in a high-acceleration flight, the protective airbag can reduce the risk of neck injury when the pilot constantly turns his head to observe the direction. The protective airbag can reduce injuries such as whiplash caused by high-speed impacts to the pilot's neck.
[0096] As some embodiments of the present invention, the neck protection device can be applied to users driving vehicles. When the user wears a protective airbag and the user is rear-ended while driving a vehicle, the protective airbag can support the neck to reduce the range of forward and backward movement of the neck caused by inertia, thereby reducing the damage to the user's neck caused by whiplash.
[0097] It should be emphasized that the application of the above-mentioned neck protection device 100 to pilots flying airplanes and users driving vehicles is only an illustrative example, and does not mean that the neck protection device 100 proposed by the present invention is limited to being applied to pilots flying airplanes and users driving vehicles.
[0098] The pipeline is connected between the gas delivery component and the airbag. When the gas in the airbag is insufficient, the gas delivery component can fill the airbag with gas through the pipeline to complete the inflation process. Moreover, the gas delivery component can discharge the gas in the airbag to the outside through the pipeline to complete the exhaust process. It can be understood that both the inflation process and the exhaust process of the neck protection device can be carried out multiple times to reasonably adjust the gas content in the airbag to meet various usage requirements of the user, and the neck protection device can be used multiple times.
[0099] As Figure 11 shown, the control method of the neck protection device includes the following steps:
[0100] S1, Detect the acceleration information through the acceleration sensor.
[0101] Among them, the acceleration sensor can detect the acceleration information of the neck protection device. The controller is communicatively connected to both the acceleration sensor and the gas delivery component. The acceleration sensor can transmit the detected acceleration information to the controller in the form of an acceleration signal (electrical signal). The controller can receive and parse the acceleration signal, and the controller can obtain the acceleration information of the neck protection device according to the acceleration signal.
[0102] S2, Judge the relationship between the acceleration information and the preset acceleration.
[0103] Among them, the controller can compare the magnitude relationship between the acceleration information and the preset acceleration to control the start and stop of the gas delivery component according to the magnitude relationship between the acceleration information and the preset acceleration.
[0104] S3, If the acceleration information is greater than the preset acceleration, control the gas delivery component to inflate the airbag.
[0105] Among them, if the acceleration information is greater than the preset acceleration, the controller can control the gas delivery component to inflate the airbag to increase the supporting force of the airbag on the neck to better buffer and protect the neck.
[0106] S4, If the acceleration information is less than or equal to the preset acceleration, control the gas delivery component to exhaust the airbag.
[0107] Among them, if the acceleration information is less than or equal to the preset acceleration, the controller controls the gas delivery component to exhaust the airbag to reduce the supporting force of the airbag on the neck, release the freedom of the pilot's neck, and make it more convenient for the user to turn their head, look up, look down, etc., and facilitate the user to observe the surrounding environment.
[0108] Thus, the start and stop of the gas delivery component can be controlled according to the detection information of the acceleration sensor to inflate the airbag or exhaust the airbag, so as to adjust the supporting force of the airbag on the neck, so that the neck protection device can buffer and protect the user's neck according to actual needs, reduce the risk of the user's neck injury, and can exhaust the airbag in some cases to facilitate the user to move the neck. In addition, the neck protection device can be automatically adjusted, which has good convenience and technological nature in use.
[0109] In some embodiments of the present invention, as Figure 1 shown, the neck protection device further includes: a pressure sensor, the controller is communicatively connected to the pressure sensor, the pressure sensor is used to detect the air pressure information of the airbag, and the controller is used to obtain the air pressure information of the airbag and control the start and stop of the gas delivery component according to the air pressure information of the airbag.
[0110] Among them, the pressure sensor can detect the air pressure information of the airbag, the pressure sensor can be communicatively connected to the controller, the pressure sensor can transmit the detected air pressure information of the airbag to the controller in the form of an air pressure signal (electrical signal form), the controller can receive and analyze the air pressure signal, and the controller can obtain the air pressure information of the airbag according to the air pressure signal, the controller can compare the size relationship between the air pressure information of the airbag and the preset air pressure value, and control the start and stop of the gas delivery component according to the relationship between the air pressure information of the airbag and the preset air pressure value.
[0111] The control method further includes: detecting the air pressure information of the airbag through the pressure sensor. If the acceleration information is greater than the preset acceleration and the air pressure value of the airbag is less than or equal to the preset air pressure value, control the gas delivery component to inflate the airbag. If the acceleration information is greater than the preset acceleration and the air pressure value of the airbag is greater than the preset air pressure value, control the gas delivery component to stop inflating.
[0112] Among them, the pressure sensor can be used in cooperation with the acceleration sensor. Specifically, when the acceleration information detected by the acceleration sensor is greater than the preset acceleration and the air pressure value of the airbag detected by the pressure sensor is less than or equal to the preset air pressure value, the controller controls the gas delivery component to work to inflate the airbag. When the acceleration information detected by the acceleration sensor is greater than the preset acceleration and the air pressure value of the airbag detected by the pressure sensor is greater than the preset air pressure value, the controller controls the gas delivery component to stop inflating.
[0113] Thus, the start and stop of the gas delivery component can be controlled according to the air pressure information of the airbag detected by the pressure sensor to accurately control the gas content in the airbag. The control process is reliable and can respond quickly, so that the airbag can better protect the user's neck and improve the user's satisfaction.
[0114] In some embodiments of the present invention, the control method of the neck protection device further includes: if the acceleration information is less than or equal to a preset acceleration and the air pressure value of the protection airbag is greater than zero, controlling the gas delivery member to exhaust the protection airbag.
[0115] Wherein, if the acceleration information detected by the acceleration sensor is less than or equal to the preset acceleration and the air pressure value of the protection airbag detected by the air pressure sensor is greater than zero, the controller controls the gas delivery member to operate to exhaust the protection airbag. In this way, the gas content in the protection airbag can be accurately controlled, the control process is reliable and can respond quickly, so as to improve the user's satisfaction.
[0116] In some embodiments of the present invention, the control method of the neck protection device further includes: if the acceleration information is less than or equal to the preset acceleration and the air pressure value of the protection airbag is less than or equal to zero, controlling the gas delivery member to stop exhausting.
[0117] Wherein, if the acceleration information detected by the acceleration sensor is less than or equal to the preset acceleration and the air pressure value of the protection airbag detected by the air pressure sensor is less than or equal to zero, the controller controls the gas delivery member to stop exhausting. In this way, the gas content in the protection airbag can be accurately controlled, the control process is reliable and can respond quickly, so as to improve the user's satisfaction.
[0118] As Figure 12 shown, as a specific embodiment of the present invention, the above control method may include the following steps:
