Description

Technical Field

[0001] This invention relates to the field of vehicle manufacturing technology, and in particular to a buoyancy airbag control system, a buoyancy airbag control method applicable to the buoyancy airbag control system, and a vehicle including the buoyancy airbag control system. Background Technology

[0002] Water-floating airbags inflate rapidly to create buoyancy support, helping vehicles stay afloat in wading, submerged, or deep water environments, thus buying crucial time for occupants to escape and for external rescue.

[0003] In existing technology, when the sensor detects that the vehicle's immersion depth has reached a set value, the system controls the water buoyancy airbags to automatically inflate and open. There is no way to manually open the water buoyancy airbags. As a result, when the vehicle is wading through water, if the system does not recognize that the water buoyancy airbags have not been activated, the water buoyancy airbags may fail to deploy, which may not guarantee the normal operation of the water buoyancy airbags. This could prevent the vehicle from successfully reaching the shore during wading and landing, causing irreparable damage to the people and the vehicle. Summary of the Invention

[0023] Unless otherwise specified, the front-back direction in this application refers to the longitudinal direction of the vehicle 1000, i.e., the X direction; the left-right direction refers to the lateral direction of the vehicle 1000, i.e., the Y direction; and the up-down direction refers to the vertical direction of the vehicle 1000, i.e., the Z direction.

[0024] The following is for reference. Figures 1-12 The present invention describes a buoyancy airbag control system 100, which enables manual deployment of the buoyancy airbag 1, improves the reliability of the deployment of the buoyancy airbag 1, thereby enhancing the safety of the vehicle 1000. It is flexible, convenient, easy to operate, easy to implement, highly practical, and widely applicable.

[0025] like Figures 1-12 As shown, according to one embodiment of the present invention, it includes: a floating airbag 1 and a reminder module 3.

[0026] The floating airbag 1 is a safety device to protect the vehicle 1000. When the vehicle 1000 encounters a water environment, the floating airbag 1 can quickly inflate to expand, thereby generating buoyancy and keeping the vehicle 1000 floating, providing escape time and safety for the driver and passengers.

[0027] The buoyancy airbag 1 is equipped with a detection structure 2 for detecting water depth. Detection structure 2 can be configured as a sensor, or multiple sensors, such as pressure sensors, angle sensors, and height sensors, to make the detected wading depth value more accurate. Detection structure 2 can detect the wading depth in real time and convert the detected actual water depth value into a water depth signal, which is then transmitted to the control module of the control system. After receiving the water depth signal, the control module analyzes and judges whether to trigger the inflation of the buoyancy airbag 1, i.e., whether the buoyancy airbag 1 should be opened.

[0028] The reminder module 3 is used to issue a wading warning when the water depth detected by the detection structure 2 exceeds a set value, and the reminder module 3 includes a manual operation unit for controlling the opening of the floating airbag 1.

[0029] In other words, the reminder module 3 is used to provide wading warnings to the driver and passengers inside vehicle 1000, alerting them that vehicle 1000 has entered water, preparing them to manually deploy the water-filled airbags 1, and providing a wading warning to facilitate timely adjustments to the driving situation and buy them time to escape, thereby improving driving safety and user experience. When vehicle 1000 enters water, the detection structure 2 converts the detected actual water depth into a water depth signal and transmits it to the control module of the control system. Upon receiving the water depth signal, the control module compares the actual detected water depth with a preset water depth value. When the actual detected water depth exceeds the preset value (i.e., the actual detected water depth is greater than or equal to the preset water depth), the reminder module 3 issues a wading warning to alert the driver and passengers that vehicle 1000 has entered water. The warning method can be set in various ways, such as voice prompts, light prompts, icon prompts, vibration prompts, etc., allowing for flexible configuration.

[0030] The reminder module 3 includes a manual operation unit, which is a structural part that can be directly operated by the driver and passengers. It can be set to touch screen operation, press operation, swing operation, etc., and is flexible and selectable. The driver and passengers can control the deployment of the water-filled airbag 1 by operating the manual operation unit, thereby realizing the manual deployment of the water-filled airbag 1, improving the deployment reliability of the water-filled airbag 1, thereby improving the safety of the vehicle 1000. It is flexible, convenient, simple to operate, easy to implement, highly practical, and has a wide range of applications.

[0031] The buoyancy airbag control system 100 according to an embodiment of the present invention, by setting a reminder module 3, executes a wading warning when the water depth detected by the detection structure 2 exceeds a set value, to remind the driver and passengers that the vehicle 1000 is wading, providing a wading warning to the driver and passengers, facilitating the driver to actively identify dangers and adjust the driving situation of the vehicle 1000 in a timely manner, thus buying time for the driver and passengers to escape, thereby improving driving safety and user experience; by setting a manual operation unit for controlling the opening of the buoyancy airbag 1, the driver and passengers can operate the manual operation unit to control the opening of the buoyancy airbag 1, thereby realizing the manual opening of the buoyancy airbag 1, improving the opening reliability of the buoyancy airbag 1, thereby improving the safety of the vehicle 1000, which is flexible, convenient, simple to operate, easy to implement, highly practical, and widely applicable.

[0032] In some embodiments, the reminder module 3 includes an instrument screen 31, which is used to display text prompts and / or issue voice prompts.

[0033] Specifically, the instrument panel 31 can display text for text prompts, for example, such as... Figure 12 As shown, when the right side of vehicle 1000 is wading through water, the displayed text can be "Vehicle 1000 has waded through water on the right side, please open the water-filled airbag 1", etc. The displayed text style is diverse and can be flexibly set according to actual needs, and is not limited to the one described in this embodiment.

[0034] The instrument panel 31 can also make voice broadcasts to issue voice prompts. For example, when the right side of the vehicle 1000 is wading through water, the voice broadcast content can be "The right side of the vehicle 1000 has been wading through water, please open the water-filled airbag 1", etc. The content of the voice broadcast is diverse and can be flexibly set according to actual needs, and is not limited to what is described in this embodiment.

[0035] The instrument panel 31 can simultaneously display text prompts and issue voice prompts, maximizing the notification to the driver and passengers that the vehicle 1000 has entered water and is in danger, thereby enabling the driver and passengers to take timely measures and improve driving safety.

[0036] In other embodiments, the reminder module 3 includes an IP display screen 32, which is used to display operation icon prompts for the floating airbag 1.

[0037] Specifically, the IP display screen 32 can display operation icon prompts for the water-floating airbag 1 to alert the driver and passengers to the operation of the water-floating airbag 1 while wading through water. For example, such as... Figure 10 As shown, the IP display screen 32 can display the interface of the vehicle's floating airbags 1 deployed. The floating airbags 1 that have been submerged in water can flash or be displayed in other colors to indicate to the driver and passengers which floating airbags 1 have been submerged in water. In this way, the display is more intuitive and helps the driver and passengers to make a quick judgment. The IP display screen 32 displays various types of operation icons for the floating airbags 1, which can be flexibly set according to actual needs and are not limited to those described in this embodiment.

[0038] In other embodiments, the reminder module 3 includes a button component 33 that provides operation button prompts when wading through water.

[0039] Specifically, the button assembly 33 can be positioned in a location easily visible and operable by the driver and passengers. For example, the button assembly 33 can be positioned on the steering wheel, dashboard, glove box, etc., allowing for flexible placement. The button assembly 33 has buttons that can be pressed. When the vehicle 1000 is wading through water, the button assembly 33 can issue operation button prompts to inform the driver and passengers that the vehicle 1000 has waded through water. For example, the button assembly 33 can issue operation button prompts such as flashing lights or turning on lights. The types of prompts are diverse and can be flexibly set according to actual needs, and are not limited to those described in this embodiment.

[0040] In some embodiments, the manual operation unit is configured as a touch-press icon that pops up after the operation icon prompt is triggered. The touch-press icon includes a first icon 321 for opening the floatation airbag 1 and a second icon 322 for canceling the opening of the floatation airbag 1.

[0041] Specifically, after the IP display screen 32 shows the operation icon prompt for the water-filled airbag 1, the driver and passengers can manually touch and click the operation icon prompt to trigger it. After the operation icon prompt is triggered, such as... Figure 11 As shown, the IP display screen 32 will display touch-sensitive icons, including a first icon 321 and a second icon 322. When the driver and passengers select that they need to deploy the water-filled airbag 1, they can touch and press the first icon 321. After touching and pressing the first icon 321, the system controls the water-filled airbag 1 to deploy, thereby realizing the manual deployment of the water-filled airbag 1. When the driver and passengers select that they do not need to deploy the water-filled airbag 1, they can touch and press the second icon 322. After touching and pressing the second icon 322, the system does not control the water-filled airbag 1 to deploy.

[0042] Therefore, after being triggered by the operation icon prompt, the first icon 321 and the second icon 322 pop up for the driver and passengers to choose, so as to open or close the water buoyancy airbag 1. This is easy to operate, highly practical, and offers a variety of choices. It avoids the situation where the water buoyancy airbag 1 opens automatically, resulting in the waste of airbags, and reduces costs.

[0043] For example, in actual design, the first icon 321 can be set to the icon style of "OK Open" and the second icon 322 can be set to the icon style of "Cancel Open". The icons can be flexibly set according to actual needs and are not limited to those described in this embodiment.

[0044] In some embodiments, the button assembly 33 includes a protective cover 331 and a button control board 332. The button control board 332 has a control button 3321, which is configured as a manual operation part. The protective cover 331 is movably connected to the button control board 332 to selectively cover the control button 3321.

[0045] Specifically, the driver and passengers can press the control button 3321 to control the deployment of the float airbag 1. The protective cover 331 protects the button control panel 332 to prevent accidental activation of the control button 3321, which could lead to the deployment of the float airbag 1 and waste, thus improving operational reliability. The protective cover 331 is movably connected to the button control panel 332, meaning it can move relative to the button control panel 332 to either cover or expose the control button 3321. When the button control panel 332 is exposed, the driver and passengers can press the control button 3321 to deploy the float airbag 1. When the button control panel 332 is covered, it protects the button control panel 332, providing flexibility and convenience.

[0046] In practical design, such as Figure 6 and Figure 7 As shown, the protective cover 331 can be rotatably connected to the button control plate 332 so that when the protective cover 331 rotates toward the button control plate 332 until the protective cover 331 rotates to cover the button control plate 332, it can block the control button 3321. When the protective cover 331 rotates away from the button control plate 332 until the protective cover 331 rotates to the point that the control button 3321 of the button control plate 332 is completely exposed, the protective cover 331 can be opened relative to the button control plate 332.

[0047] Furthermore, the protective cover 331 is configured to open when wading through water, and the control button 3321 is configured to light up when wading through water to provide an operation button prompt.

[0048] In other words, when vehicle 1000 is in water, the protective cover 331 moves away from the button control panel 332 so that the protective cover 331 is in the open state. At this time, the control button 3321 is exposed to the external environment, and the driver and passengers can operate it. At the same time, the control button 3321 lights up to provide an operation button prompt, indicating to the driver and passengers that vehicle 1000 has been in water and the floating airbag 1 needs to be deployed.

[0049] In the actual design, the control button 3321 is set to emit red light or other highly saturated lights when wading through water to conspicuously alert the driver and passengers. It can also make the lit light flash frequently to further alert the driver and passengers, so that the driver and passengers can quickly identify the danger and make a judgment.

[0050] In some embodiments, the control button 3321 includes a full-open button 33211 and multiple single-open buttons 33212, wherein there are multiple floating airbags 1 and each single-open button 33212 corresponds to one of them. The single-open button 33212 is configured to control the corresponding floating airbag 1 to open individually, and the full-open button 33211 is configured to control all of the multiple floating airbags 1 to open.

[0051] Specifically, the floating airbag 1 can be set to two, three, four or even more. Setting up the floating airbag 1 allows the vehicle 1000 to float by inflating multiple floating airbags 1, which improves the floating effect of the vehicle 1000 and thus further enhances the safety of the vehicle 1000. Moreover, if one of the floating airbags 1 is damaged or fails, the other floating airbags 1 can still work normally, protecting the floating effect of the vehicle 1000 and improving the rescue time.

[0052] Multiple buoyancy airbags 1 are configured with one-to-one correspondence between them and multiple individual opening buttons 33212. That is, each buoyancy airbag 1 is equipped with a corresponding individual opening button 33212. In other words, the number of individual opening buttons 33212 is the same as the number of buoyancy airbags 1, allowing each buoyancy airbag 1 to be manually opened. Each individual opening button 33212 can control the corresponding buoyancy airbag 1 to open independently, thus preventing the opening of buoyancy airbags that are not in water and avoiding waste of airbags.

[0053] The full-open button 33211 can control all multiple water-floating airbags 1 to be deployed, thereby improving the speed and convenience of operation, preventing the vehicle 1000 from quickly sinking into deeper water, and buying more time for rescue.

[0054] For example, such as Figures 1-3As shown, four buoyancy airbags 1 can be installed. The four buoyancy airbags 1 can be installed at the bottom of the vehicle 1000 and at the four cardinal points of the vehicle 1000. Specifically, one buoyancy airbag 1 can be installed at the front of the vehicle 1000, one buoyancy airbag 1 at the rear of the vehicle 1000, one buoyancy airbag 1 at the left side of the vehicle 1000, and another buoyancy airbag 1 at the right side of the vehicle 1000. This ensures that the vehicle 1000 can float on water by means of the corresponding buoyancy airbag 1 when it is wading on any side.

[0055] like Figure 4 As shown, there are four single-opening buttons 33212, each corresponding to one of the four water-filled airbags 1. The buttons 33212 can be marked with their orientation, such as front, rear, left, and right, to correspond to the installation positions of the four water-filled airbags 1. Thus, pressing the button marked "front" will control the water-filled airbag 1 installed directly in front of the vehicle 1000 to open individually, and pressing the button marked "rear" will... When button 33212 is pressed, the single-open button 33212 can control the water-filled airbag 1 installed at the rear of vehicle 1000 to open independently. When the single-open button 33212 marked "left" is pressed, the single-open button 33212 can control the water-filled airbag 1 installed on the left side of vehicle 1000 to open independently. When the single-open button 33212 marked "right" is pressed, the single-open button 33212 can control the water-filled airbag 1 installed on the right side of vehicle 1000 to open independently.

[0056] like Figure 4 As shown, the full-open button 33211 can be positioned in the center, with each individual open button 33212 arranged around it. This saves space, reduces the overall size of the button control panel 332, and allows it to be placed in any location. The full-open button 33211 can also be marked with "Full Open" or "Full Explosion" to alert the driver and passengers. When the full-open button 33211 is pressed, it controls all four water-filled airbags 1 to deploy simultaneously.

[0057] It should be noted that the font labels on the single-open button 33212 and the full-open button 33211 can be set to Chinese or English, and can be flexibly set according to the actual situation.

[0058] Thus, through the multi-faceted and precise reminders from the IP display screen 32, the instrument panel screen 31, and the button assembly 33, the driver and passengers can promptly notice the water wading situation and choose whether to activate the water buoyancy airbag 1 based on the actual situation.

[0059] In some embodiments, the floating airbag control system 100 further includes an inflation structure 4, which includes an inflation source 41 and a control valve 42. The control valve 42 is used to selectively connect the inflation source 41 to the floating airbag 1, and a manual operation unit is used to switch the connection state of the control valve 42.

[0060] Specifically, the inflation source 41 is used to provide high-pressure gas to the floating airbag 1, and the control valve 42 is used to control the flow of gas. The control valve 42 can be connected to the floating airbag 1 so that the gas provided by the inflation source 41 can flow to the floating airbag 1 through the control valve 42 to inflate the floating airbag 1, causing the floating airbag 1 to expand and unfold, so that one side or the entire vehicle 1000 can float. Alternatively, the control valve 42 can be disconnected from the floating airbag 1 so that the gas provided by the inflation source 41 cannot flow to the floating airbag 1 through the control valve 42, so that the floating airbag 1 cannot open.

[0061] The manual operation unit can switch the connection state of the control valve 42, that is, it can be operated to make the control valve 42 and the float airbag 1 connected or disconnected, so as to open or close the float airbag 1. For example, when the single open button 33212 or the full open button 33211 is pressed, or when the first icon 321 is touched, the float airbag 1 and the control valve 42 can be switched from the disconnected state to the connected state, so as to inflate the float airbag 1.

[0062] It should be noted that both the control valve 42 and the inflation source 41 are controlled by electrical signals from the control system. When the user touches and presses the first icon 321 or presses the single-open button 33212 or the full-open button 33211, an airbag opening signal is triggered. After receiving the airbag opening signal, the control system sends an airbag opening signal to the inflation source 41 and the control valve 42. When the inflation source 41 receives the airbag opening signal transmitted by the control system, the inflation source 41 begins to inflate the floating airbag 1. At the same time, the control valve 42 is connected to the floating airbag 1, so that the gas provided by the inflation source 41 can flow smoothly into the floating airbag 1 through the control valve 42.

[0063] In practical design, the control valve 42 can be set as a solenoid valve, and the inflation source 41 can be set as an inflation pump, a high-pressure gas cylinder, a gas generator, etc. The high-pressure gas cylinder can store high-pressure gas in advance, and the high-pressure gas is released into the floating air bag 1 to inflate the floating air bag 1. The gas generator generates a large amount of gas through a chemical reaction to inflate the floating air bag 1. The inflation pump can compress air by driving the piston or impeller through a motor to generate high-pressure gas to inflate the floating air bag 1. The inflation source 41 can be set in various forms and can be flexibly set according to actual needs.

[0064] In some embodiments, the control valve 42 has an air inlet and multiple air outlets. The air inlet is connected to the air source 41. There are multiple floating airbags 1, and the multiple floating airbags 1 are connected to the multiple air outlets in a one-to-one correspondence. The air inlet and the multiple air outlets are selectively connected.

[0065] Specifically, the number of outlet valves can be set to two, three, four, or more, and the number of floating airbags 1 can also be set to two, three, four, or more. The number of outlet valves corresponds to the number of floating airbags 1, that is, the number of outlet valves and the number of floating airbags 1 can be set to be the same, so that each floating airbag 1 is connected to an outlet valve. The inlet valve is connected to the inflation source 41, so that the high-pressure gas provided by the inflation source 41 can flow into the control valve 42 through the inlet valve. The inlet valve is selectively connected to multiple outlet valves, that is, the inlet valve can be connected to or disconnected from multiple outlet valves. In this way, the high-pressure gas passing through the control valve 42 can flow through one, two, three, or all of them. The gas flows out of the outlet valve into the corresponding float airbag 1 to inflate the corresponding float airbag 1. In other words, the high-pressure gas provided by the inflation source 41 can fill one, two, or all of the float airbags 1, so as to adjust the posture of the vehicle 1000 in a timely manner according to the different water wading postures of the vehicle 1000, intervene in the vehicle posture in advance, and avoid the vehicle 1000 from further wading or causing other secondary damage. Since the loss caused by the vehicle 1000 running out of water and the possible casualties to the occupants are no less than those caused by a fire, the earlier the intervention is carried out in the early stage, the more likely it is to save more of the vehicle 1000 or personal injury, and better cope with various driving conditions to protect the life and property safety of the driver.

[0066] In practical design, control valve 42 can be configured as a multi-way valve. For example, when four floating airbags 1 are configured, control valve 42 can be configured as a five-way valve with one inlet valve and four outlet valves. The four outlet valves are connected one-to-one with each other to reduce the number of individual control valves. This avoids connecting one floating airbag 1 to one control valve, which would increase the number of components. Therefore, by configuring control valve 42 as a multi-way valve, the number of components can be reduced, making the pipeline layout more compact and reducing the space occupied by the floating airbag control system 100.

[0067] In practice, active and passive wading include frontal entry into water, rear entry into water, frontal entry into water, side entry into water, and reverse entry into water posture. Users can choose different buoyancy airbag filling methods according to different wading postures.

[0068] It should be noted that when the internal pressure of the water-floating airbag 1 reaches the predetermined pressure value, the control valve 42 will automatically close and stop inflation to prevent the water-floating airbag 1 from tearing or exploding due to excessive pressure. After the danger of wading has passed, the water-floating airbag 1 can be deflated by pressing and holding the control button 3321 to return it to the vehicle. For example, it can be pressed and held for three, four, or five seconds. In this way, the water-floating airbag 1 can be reused, reducing costs.

[0069] In some embodiments, the bottom of the floating airbag 1 is provided with a wear-resistant layer, which includes fibers and rubber.

[0070] Specifically, the fiber has high strength, which can effectively resist external impact, and is lightweight. The rubber has high elasticity and wear resistance, and can undergo significant deformation under external force and quickly return to its original shape. Therefore, by setting a wear-resistant layer including fiber and rubber at the bottom of the floating airbag 1, the wear resistance of the bottom of the floating airbag 1 can be effectively improved, ensuring that the floating airbag 1 will not rupture when it rubs against the ground, thus ensuring the reusability of the floating airbag 1.

[0071] In practice, the buoyancy airbag 1 can be installed at the bottom of the vehicle 1000 and connected to the vehicle chassis. When not triggered to open, the buoyancy airbag 1 can be placed in the storage box to store it. When the buoyancy airbag 1 inflates to a certain extent, it will pop out from the pressure door of the storage box to float the vehicle 1000 on the water surface, preventing water from entering the vehicle 1000 or sinking, thus buying time for the driver and passengers to carry out self-rescue or external rescue and avoiding personal injury or property damage.

[0072] The present invention also proposes a method for controlling a floating airbag.

[0073] The buoyancy airbag control method according to embodiments of the present invention is applicable to the buoyancy airbag control system of any of the above embodiments, and the control method includes: S1: Obtain the vehicle's wading signal.

[0074] Specifically, when the vehicle is wading through water, the detection structure 2 converts the detected water depth value into a water depth signal and transmits it to the control module of the control system. After receiving the water depth signal, the control module compares the actual detected water depth value with the preset water depth value. When the actual detected water depth value exceeds the preset water depth value, that is, when the actual detected water depth value is greater than or equal to the preset water depth value, it is determined that the vehicle 1000 has waded through water, that is, the wading signal of the vehicle 1000 is obtained.

[0075] In actual design, the control module can be set as the vehicle's electronic control unit (ECU).

[0076] S2: Based on the water wading signal, the control reminder module executes a water wading prompt.

[0077] Specifically, based on the acquired water wading signal, the control system controls the reminder module 3 to execute a water wading prompt, so as to remind the driver and passengers that the buoyancy airbag 1 at a certain position of the vehicle 1000 needs to be deployed when wading.

[0078] It should also be noted that the reminder module 3 can issue a wading warning when the water depth detected by the detection structure 2 exceeds a first preset value. The first preset value can be set as a safety threshold that affects the safety of the vehicle 1000, the driver, and passengers. The driver and passengers can choose to open or close the float airbag 1. However, if the water depth detected by the detection structure 2 exceeds a second preset value, and the second preset value is greater than the first preset value, the water depth value of which would affect the life safety of the driver and passengers. In this case, if the control system does not detect the float airbag 1 opening, that is, if the driver and passengers do not manually open the float airbag 1, the control system will automatically control the float airbag 1 to open to ensure the safety of the passengers. In other words, the control system determines to transfer the control of the wading float airbag 1 to the vehicle operator. The author only manually deploys the water-filled airbag 1 after it has successfully deployed. However, this transfer of control does not mean that the control system has lost ultimate control. If the control system detects that the water depth has threatened the lives of the vehicle occupants and the water-filled airbag 1 has not deployed, the control system will reclaim control and automatically deploy the water-filled airbag 1. This control method can also avoid many malfunction scenarios. For example, when passing through a water-filled bridge or puddle, a person's subjective judgment may not be able to clearly determine whether the water depth ahead allows the water-filled airbag 1 to work. If the person forcibly drives through the water or manually deploys the water-filled airbag 1 without careful judgment, the water-filled airbag 1 may fail to deploy properly, restricting the vehicle's movement. In this case, the control system can also prevent the water-filled airbag 1 from deploying.

[0079] The present invention also proposes a vehicle 1000.

[0080] The vehicle 1000 according to an embodiment of the present invention includes the buoyancy airbag control system 100 of any of the above embodiments.

[0081] According to an embodiment of the present invention, the vehicle 1000, by setting a reminder module 3, executes a wading warning when the water depth detected by the detection structure 2 exceeds a set value, to remind the driver and passengers that the vehicle 1000 is wading, providing a wading warning to the driver and passengers, facilitating the driver's proactive identification of dangers and timely adjustment of the vehicle 1000's driving situation during driving, and buying time for the driver and passengers to escape, thereby improving driving safety and user experience; by setting a manual operation unit for controlling the opening of the buoyancy airbag 1, the driver and passengers can operate the manual operation unit to control the opening of the buoyancy airbag 1, thereby realizing the manual opening of the buoyancy airbag 1, improving the opening reliability of the buoyancy airbag 1, thereby improving the safety of the vehicle 1000, which is flexible, convenient, simple to operate, easy to implement, highly practical, and widely applicable.
