The airbag includes an airbag body, a gas generator, an upper tether, and a lower tether. The upper panel of the airbag body has an upper connection point and a lower connection point. Both the upper and lower tethers are connected to the gas generator, with one end of the upper tether connected to the upper connection point and the other end of the lower tether connected to the lower connection point. In the deployed state of the airbag body, the line connecting the upper and lower connection points on the upper panel passes through a first center position of the upper panel, and the distance between the upper connection point and the first center position is less than the distance between the lower connection point and the first center position, allowing the airbag body to tilt towards a first side.

Description

Technical Field

[0001] This application relates to the field of vehicle manufacturing technology, specifically to an airbag, a half-spoke steering wheel assembly, and a vehicle. Background Technology

[0002] Traditional steering wheels are mostly round, consisting of spokes and a rim surrounding the spokes. With the advancement of intelligent driving technology, the demand for larger front entertainment displays is increasing, but the spokes of traditional steering wheels often obstruct the screen, leading to the emergence of irregularly shaped, asymmetrical, half-spoke steering wheels.

[0003] However, due to the lack of support from the upper half of the steering wheel spokes, the airbag on the half-spoke steering wheel will tilt upwards during deployment. This causes the airbag to be pushed forward when the driver lands on it, resulting in the driver's head and chest hitting the bottom of the steering wheel. This can lead to excessive neck bending moment and excessive head and chest injury values. Summary of the Invention

[0004] In view of this, this application provides an airbag that prevents the airbag from warping during deployment, thereby effectively protecting the driver's safety. Furthermore, this application also provides a half-spoke steering wheel assembly including the aforementioned airbag and a vehicle.

[0005] To achieve the above objectives, this application provides the following technical solution: An airbag comprising: The airbag body includes an upper piece and a lower piece; the upper piece has an upper connection point and a lower connection point; The gas generator is sealed to the lower plate; An upper pull strap and a lower pull strap are disposed inside the airbag body; one end of the upper pull strap is connected to the gas generator, and the other end is connected to the upper connection point; one end of the lower pull strap is connected to the gas generator, and the other end is connected to the lower connection point. Wherein, the center position of the upper piece is the first center position, and in the arrangement direction of the upper and lower pull straps, the side of the gas generator closer to the lower connection point is the first side; in the deployed state of the airbag body, the line connecting the upper connection point and the lower connection point on the upper piece passes through the first center position, and the distance between the upper connection point and the first center position is less than the distance between the lower connection point and the first center position, so that the airbag body can tilt towards the first side.

[0006] Optionally, the center position of the lower piece is a second center position; In the arrangement direction of the upper and lower pull straps, the gas generator is positioned offset from the second center position in a direction away from the lower connection point.

[0007] Optionally, the distance between the upper connection point and the first center position is A, and the distance between the lower connection point and the first center position is B, with the difference between A and B ranging from 30mm to 100mm.

[0008] Optionally, the length of the pull-down strap is less than the length of the pull-up strap.

[0009] Optionally, the length of the upper pull strap is 250mm-320mm, and the length of the lower pull strap is 130mm-230mm.

[0010] Optionally, the distance between the gas generator and the second center position is 30mm-80mm.

[0011] Optionally, both the upper connection point and the lower connection point are provided with a reinforcing structure.

[0012] Optionally, the reinforcing structure includes sutures, or The reinforcing structure includes reinforcing sheets that cover the upper connection point and the lower connection point respectively, and sutures that fix the reinforcing sheets to the upper sheet.

[0013] A half-spoke steering wheel assembly, comprising: The steering wheel body has a mounting bracket; The airbag is any one of the airbags described above, and the airbag is disposed on the mounting base; and, in the deployed state of the airbag body, in the arrangement direction of the upper and lower pull straps, the upper connection point of the airbag is close to the side of the steering wheel body with a missing rim, and the lower connection point of the airbag is close to the side of the steering wheel body with an intact rim.

[0014] A vehicle comprising the airbag described in any of the preceding claims or the half-spoke steering wheel assembly described above.

[0015] The airbag provided in this application has an upper connection point and a lower connection point connected on the upper piece that pass through the first center position. Furthermore, the distance between the upper connection point and the first center position is less than the distance between the lower connection point and the first center position. During the expansion and deployment of the airbag body, the upper and lower straps work together to apply an asymmetrical constraint force to the airbag body, thereby enabling the airbag body to tilt toward the first side of the gas generator. Based on the above, when installing the airbag on the steering wheel, the angle of the airbag relative to the steering wheel is adjusted so that the first side of the gas generator aligns with the intact side of the steering wheel rim. This way, during the airbag's expansion, the upper and lower straps work together to apply a force towards the intact side of the steering wheel rim, balancing the asymmetrical forces caused by the difference in support between the missing and intact sides of the rim. This corrects the airbag's posture during deployment, preventing it from tilting upwards. Thus, when the driver lunges towards the airbag due to collision inertia, they are not pushed away by the tilted airbag, ensuring the airbag stably covers the driver's chest and head area, guaranteeing driver safety.

Detailed Implementation

[0025] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0026] This application discloses a vehicle, including but not limited to new energy vehicles, fuel vehicles, and hybrid vehicles. Furthermore, the vehicle includes, but is not limited to, passenger cars and public vehicles.

[0027] Furthermore, the vehicle in this embodiment includes a vehicle body, and a half-spoke steering wheel assembly is provided inside the vehicle body. The half-spoke steering wheel assembly includes a steering wheel body 200 and an airbag 100 disposed in the steering wheel body 200 (see details). Figure 6 and Figure 7 ).

[0028] The aforementioned half-spoke steering wheel assembly refers to a steering wheel assembly with an asymmetrical structural design. The rim of its steering wheel body 200 is not a traditional complete ring; instead, the upper half of the rim near the driver (the gripping portion of the steering wheel body 200, hereinafter the same) is missing, forming a half-spoke shape with only the lower half of the rim intact. Compared to a full-spoke steering wheel assembly, the half-spoke assembly effectively reduces obstruction of the front entertainment display screen, meeting the driver's viewing needs for screen information in intelligent driving scenarios.

[0029] Furthermore, the half-spoke steering wheel assembly of this application includes a steering wheel body 200 and a mounting bracket, which is disposed at the steering column connection portion of the steering wheel body 200 and is used to install the airbag 100.

[0030] For ease of description, the side of the half-spoke steering wheel assembly lacking the rim structure will be referred to as the rim-missing side, and the side of the half-spoke steering wheel assembly with the rim completed will be referred to as the rim-complete side.

[0031] In specific application scenarios, such as Figure 1 and Figure 2 As shown, when a vehicle collision occurs and the airbag 100 is deployed, the intact side of the half-spoke steering wheel assembly can support the airbag body 2, while the side with the missing rim cannot. This causes uneven stress on the airbag body 2 during inflation, making it prone to tilting upwards towards the side with the missing rim (i.e., the upper half in front of the driver). This upward tilt prevents the airbag body 2 from accurately covering the driver's effective protection area. Furthermore, when the driver lunges towards the airbag due to inertia, the tilted airbag will be pushed forward, failing to provide effective cushioning support and instead causing significant bending moment to the driver's neck. Simultaneously, the head and chest may directly contact hard structures such as the steering wheel body 200, resulting in exceeding critical safety indicators such as head injury value and chest compression.

[0032] To address the aforementioned issues, this application provides an airbag 100 that uses an eccentrically positioned strap assembly to apply an anti-uplift force to the airbag body 2. This balances the asymmetrical forces generated by the difference in support between the side with a missing rim and the side with a complete rim, thereby achieving posture correction of the airbag body 2 during deployment and ensuring that the airbag body 2 can stably cover the driver's chest and head area.

[0033] Of course, this application uses the example of the airbag 100 being installed on the steering wheel of a vehicle for illustration, which does not constitute a special limitation on this application. The airbag 100 can also be applied to other locations with uneven support, such as the passenger-side dashboard area of ​​a vehicle. Wherever there is a scenario where the airbag's posture may shift due to the installation environment, the technical concept of this application can be used for improvement. Next, the airbag 100 of this application will be described in detail with reference to its specific structure.

[0034] like Figures 3-7 As shown, the airbag 100 in this embodiment includes a sensor assembly, a control module (the sensor assembly and control module are not shown in the figure), an airbag body 2, a gas generator 1, an upper pull strap 3, and a lower pull strap 4.

[0035] The sensor assembly is used to monitor vehicle collision signals in real time and transmit them to the control module.

[0036] In an exemplary embodiment, the sensor assembly includes a trigger collision sensor, a protective collision sensor, an acceleration sensor, and a rollover sensor. During vehicle operation, these various sensors work together to sensitively capture key parameters such as the impact acceleration, collision force, and collision direction experienced by the vehicle. When a collision occurs, the sensor assembly detects abnormal signals within a very short time and converts these signals into electrical signals, sending them to the control module to provide a triggering basis for the timely deployment of the airbag 100.

[0037] Regarding the placement of sensor components, they are generally positioned in critical areas prone to collisions, such as the front and sides of the vehicle, to ensure rapid and accurate detection of collision events and guarantee the timeliness and reliability of the airbag system. However, this is not a limitation of this application; during implementation, sensors can be placed in different locations on the vehicle as needed.

[0038] As the core control unit of the airbag 100 system, the control module is responsible for receiving collision signals transmitted from the sensor components and performing signal analysis, processing, and logical judgment. The control module has a complex preset collision algorithm and safety trigger thresholds. When the received collision signal exceeds the preset threshold, the control module immediately sends an ignition command to the gas generator 1. Simultaneously, the control module also has a self-test function. Each time the vehicle starts and during driving, it automatically checks key components such as the sensor components, gas generator 1, and wiring connections. If any abnormality is detected, it alerts the driver via a malfunction indicator light on the instrument panel, ensuring that the airbag 100 system is always in normal working order. Furthermore, the control module may communicate with other electronic systems in the vehicle, such as the vehicle stability system and seatbelt pretensioners, to achieve multi-system collaborative operation and further enhance collision protection.

[0039] The airbag body 2 is the core component of the airbag 100. Its main function is to rapidly inflate to form a buffer pad when a vehicle collides, thereby protecting the driver's head, chest and other critical parts from severe impact.

[0040] like Figure 3 and Figure 4 As shown, the airbag body 2 includes an upper piece 201 and a lower piece 202. The edges of the upper piece 201 and the lower piece 202 are sealed together by stitching or heat sealing to form a closed cavity, so as to ensure that the gas generated by the gas generator 1 can effectively inflate the airbag.

[0041] Regarding the materials of the upper piece 201 and the lower piece 202, in specific implementation, the upper piece 201 and the lower piece 202 are usually made of high-strength, high-elasticity fabric materials, such as nylon and / or polyester fibers, which have good tear resistance and breathability, so that the airbag body 2 can withstand huge impact forces while ensuring that the gas can fill the entire airbag evenly and quickly.

[0042] Furthermore, such as Figures 3-5 As shown, the upper piece 201 has an upper connection point 2011 for connecting the upper traction strap 3 and a lower connection point 2012 for connecting the lower traction strap 4. These two connection points are key stress-bearing locations connecting the upper traction strap 3 and the lower traction strap 4, and their structural strength directly affects the restraint effect of the straps on the airbag body 2. To prevent the connection points from tearing due to excessive force during airbag deployment, both the upper connection point 2011 and the lower connection point 2012 are equipped with reinforcing structures.

[0043] In one alternative embodiment, the reinforcing structure includes stitching lines that increase the thickness and tensile strength of the fabric in that area by making multiple, dense stitches around the connection point.

[0044] In another preferred embodiment, the reinforcing structure includes reinforcing sheets covering the upper connection point 2011 and the lower connection point 2012 respectively, and sutures that securely connect the reinforcing sheets to the upper piece 201. The reinforcing sheets can be made of the same or higher strength material as the upper piece 201, and their shape can be circular, square, or other geometric shapes adapted to the shape of the connection point. By tightly fixing the reinforcing sheets to the connection point of the upper piece 201 with sutures, the stress at the connection point can be significantly dispersed, further improving the reliability and durability of the connection.

[0045] The gas generator 1 is the core component of the airbag 100 system that generates gas. It is sealed to the lower panel 202 of the airbag body 2 to ensure that the generated gas can be fully filled into the airbag body 2.

[0046] In an exemplary embodiment, the lower panel 202 of the airbag body 2 has an inflation port and an exhaust port. The gas generator 1 is connected to the position of the inflation port on the lower panel 202 to ensure that the gas can efficiently enter the interior of the airbag body 2 after it is generated. This application does not specifically limit the specific connection method between the gas generator 1 and the lower panel 202. For example, in specific implementations, a sealing structure such as a sealing flange can be used to achieve a sealed connection between the gas generator 1 and the lower panel 202. The exhaust port of the airbag body 2 is used to release some gas in a timely manner after the airbag deploys, avoiding excessive pressure inside the airbag and causing secondary injury to the human body. Simultaneously, the slow release of gas extends the buffer time and further enhances the protective effect.

[0047] The upper pull strap 3 and the lower pull strap 4 are flexible restraint components disposed inside the airbag body 2. Their two ends are connected to the gas generator 1 and the upper panel 201 of the airbag body 2, respectively, to effectively control the shape of the airbag body 2 during airbag deployment. Specifically, in this embodiment, both the upper pull strap 3 and the lower pull strap 4 are disposed inside the airbag body 2. One end of the upper pull strap 3 is connected to the gas generator 1, and the other end is connected to the upper connection point 2011 of the upper panel 201. Similarly, one end of the lower pull strap 4 is connected to the gas generator 1, and the other end is connected to the lower connection point 2012 of the upper panel 201. Through this connection method, the upper pull strap 3 and the lower pull strap 4 can apply tension to the upper panel 201 of the airbag body 2 when the airbag inflates, thereby limiting the thickness of the inflated airbag body 2.

[0048] Furthermore, the center position of the upper piece 201 is the first center position 2013, which is in the arrangement direction of the upper pull strap 3 and the lower pull strap 4 (the specific arrangement direction of the upper pull strap 3 and the lower pull strap 4 can be found in the reference). Figure 3 In the X direction, the side of the gas generator 1 closest to the lower connection point 2012 is designated as the first side. When the airbag body 2 is deployed, the line connecting the upper connection point 2011 and the lower connection point 2012 on the upper piece 201 passes through the first center position 2013, and the distance between the upper connection point 2011 and the first center position 2013 is less than the distance between the lower connection point 2012 and the first center position 2013. With this configuration, during the inflation of the airbag body 2, the upper pull strap 3 and the lower pull strap 4 work together to apply an asymmetrical constraint force to the airbag body 2, thereby allowing the airbag body 2 to tilt towards the first side.

[0049] When the airbag 100 in this application is installed on the steering wheel body 200, the angle of the airbag 100 relative to the steering wheel body 200 is adjusted so that the first side of the gas generator 1 corresponds to the intact rim side of the steering wheel body 200. In this way, when the airbag 100 installed on the steering wheel body 200 is triggered, the gas generated by the gas generator 1 rapidly inflates the airbag body 2, and the airbag body 2 begins to expand and deploy. Furthermore, after the airbag body 2 deploys, in the arrangement direction of the upper pull strap 3 and the lower pull strap 4, the upper connection point 2011 of the airbag 100 is closer to the side of the steering wheel body 200 where the rim is missing, and the lower connection point 2012 of the airbag 100 is closer to the intact rim side of the steering wheel body 200.

[0050] As described above, in the airbag 100 of this application, during the inflation and deployment process, the upper strap 3 and the lower strap 4 work together to apply an asymmetrical constraint force to the airbag body 2, thereby allowing the airbag body 2 to tilt towards the first side of the gas generator 1. The first side of the gas generator 1 corresponds to the intact rim side of the steering wheel body 200. Therefore, during the deployment process, the upper strap 3 and the lower strap 4 work together to apply a force to the airbag body 2 towards the intact rim side of the steering wheel body 200, balancing the asymmetrical force generated by the difference in support between the missing and intact rim sides of the airbag body 2. This achieves posture correction of the airbag body 2 during deployment, preventing it from tilting upwards during inflation and deployment. Thus, when the driver lunges towards the airbag due to collision inertia, the problem of being pushed away due to the tilting of the airbag body 2 can be avoided, ensuring that the airbag body 2 can stably cover the driver's chest and head area, thereby ensuring the driver's safety.

[0051] In one exemplary implementation, such as Figure 5 As shown, the upper piece 201 has a corolla 2014 surrounding the first center position 2013 and used for structural reinforcement; the upper pull strap 3 is connected to the corolla 2014 by a suture (that is, the upper connection point 2011 is located on the corolla 2014), and the lower pull strap 4 is connected to the outside of the corolla 2014 by a suture (that is, the lower connection point 2012 is located on the outside of the corolla 2014). At the same time, by increasing the connection area between the lower pull strap 4 and the upper piece 201 (that is, in this embodiment, the connection area between the lower pull strap 4 and the upper piece 201 is greater than the connection area between the upper pull strap 3 and the upper piece 201), the connection strength between the lower pull strap 4 and the upper piece 201 is ensured, and the lower connection point 2012 of the upper piece 201 is prevented from being torn during the expansion and deployment of the airbag body 2.

[0052] For ease of description, such as Figure 5 As shown, the distance between the upper connection point 2011 and the first center position 2013 is defined as A, and the distance between the lower connection point 2012 and the first center position 2013 is defined as B.

[0053] Understandably, in practical implementation, the larger the difference between A and B, the stronger the asymmetric constraint force exerted by the upper traction strap 3 and the lower traction strap 4 on the airbag body 2, the greater the degree to which the airbag body 2 tilts towards the intact rim side, and the more significant the correction effect on the upward tilting trend of the airbag body 2. However, if the difference between A and B is too large, the lower traction strap 4 will not be able to effectively constrain the thickness of the airbag body 2 after deployment. This thickness refers to the distance between the upper piece 201 and the lower piece 202 of the airbag body 2 after deployment. Therefore, the difference between A and B needs to be comprehensively designed and optimized based on factors such as the size of the airbag body 2 and the desired deployment posture.

[0054] In an exemplary embodiment, the difference between A and B ranges from 30mm to 100mm. Within this range, it is possible to ensure that the upper tether strap 3 and the lower tether strap 4 provide sufficient asymmetric constraint force to effectively correct the upward trend of the airbag body 2, while also preventing the lower tether strap 4 from failing to constrain the thickness of the airbag body 2 due to an excessively large difference.

[0055] In some embodiments, the length of the lower pull strap 4 is shorter than the length of the upper pull strap 3. This allows the lower pull strap 4 to be tensioned earlier than the upper pull strap 3 when the airbag body 2 begins to inflate, applying tension to the upper panel 201 of the airbag body 2. Since one end of the lower pull strap 4 is connected to the lower connection point 2012 near the intact side of the wheel rim, its shorter length allows the restraint force on that side to take effect more quickly, thereby suppressing any upward tilting tendency that may occur in the initial stage of airbag deployment, further improving the timeliness and effectiveness of attitude correction.

[0056] Meanwhile, the length difference between the lower pull strap 4 and the upper pull strap 3, together with the distance difference between the upper connection point 2011 and the lower connection point 2012 to the first center position 2013 (i.e., the difference between A and B), constitute a complete system of asymmetric constraint on the airbag body 2, ensuring that the airbag body 2 can maintain a stable posture throughout the entire deployment process.

[0057] Furthermore, in some embodiments, the length of the upper tether strap 3 is 250mm-320mm, and the length of the lower tether strap 4 is 130mm-230mm. Within this length range, it is possible to ensure that the lower tether strap 4 is quickly tensioned and applies restraint force in the early stage of airbag deployment, while also allowing the upper tether strap 3 to provide continuous tension as the airbag further expands. This avoids the lower tether strap 4 from reaching its tensile limit too early due to being too short, which could lead to its own breakage or the rupture of the airbag body 2. At the same time, it also avoids the upper tether strap 3 being too long and unable to effectively limit the thickness of the airbag.

[0058] As mentioned earlier, by asymmetrically connecting the upper pull strap 3 and the lower pull strap 4 to the upper piece 201, the airbag body 2 can be prevented from tilting upwards during inflation, thus mitigating the problem of the airbag body 2 being pushed away when the driver throws onto it. However, in specific application scenarios, due to the tilted setting of the steering wheel body 200, the airbag body 2 is also tilted after deployment due to the influence of the installation angle of the steering wheel body 200. This means that the airbag body 2 can still be easily pushed away when the driver throws onto it.

[0059] For ease of description, the center position of the lower piece 202 will be defined as the second center position 2021 below.

[0060] Based on the above problems, in some embodiments, such as Figure 4As shown, in the arrangement direction of the upper pull strap 3 and the lower pull strap 4, the gas generator 1 is offset from the second center position 2021 in a direction away from the lower connection point 2012. In this way, by setting the gas generator 1 off-center, after the airbag body 2 inflates and deploys, more of its portion will be on the intact side of the steering wheel body 200 rim. This allows the airbag body 2 to extend to the driver's chest. Thus, when the driver lunges towards the airbag body 2, the driver's chest area will first contact the airbag body 2, clamping the airbag body 2 between the chest and the steering wheel body 200 (see reference for details). Figure 6 and Figure 7 In this way, the airbag body 2 can be effectively restricted, preventing it from being pushed away, and thus effectively preventing the driver's chest from directly contacting the steering wheel body 200, ensuring that the airbag 100 can play an effective protective role.

[0061] It should be noted that, as Figure 3 and Figure 4 As shown, this application, through the cooperation of the lower pull strap 4 and the upper pull strap 3, enables the airbag body 2 to have a recessed area in the deployed state. This recessed area corresponds to the driver's chest. In this way, the airbag body 2, which extends to the driver's chest, can be prevented from squeezing the driver's chest during the expansion and deployment process, thereby reducing the driver's chest injury caused by the airbag and ensuring the driver's personal safety.

[0062] In practice, the shape of the recessed area can be adjusted by adjusting the length of the upper pull strap 3 and the lower pull strap 4, as well as the connection position of the upper pull strap 3 and the lower pull strap 4 on the upper piece 201.

[0063] Understandably, the greater the distance between the gas generator 1 and the second center position 2021, the more airbags will be positioned to cover the driver's chest after the airbag body 2 deploys, thus better restraining the airbag body 2 and preventing it from being pushed away. However, in practical implementation, considering that the side with the missing wheel rim needs to have sufficient volume of airbag body 2 to support the driver's head, in some embodiments, the distance between the gas generator 1 and the second center position 2021 is limited to 30mm-80mm. This ensures that the airbag body 2 has sufficient extension on the side with the intact wheel rim to effectively restrain it from being pushed away, while also ensuring that the volume of the airbag body 2 on the side with the missing wheel rim is sufficient to reliably support the driver's head, achieving comprehensive protection for the driver's head and chest.
