Description

Technical Field

[0001] This utility model relates to the field of vehicle parts technology, specifically to an airbag device and a vehicle. Background Technology

[0002] With the development of vehicle technology, the automotive industry is paying increasing attention to and emphasizing pedestrian protection. In particular, because vehicle body structures require high rigidity and crashworthiness, the high-strength structure of the vehicle's A-pillar significantly increases the risk of severe head injuries to pedestrians in the event of a collision.

[0003] Currently, pedestrian protection airbags are a widely used method of pedestrian protection. For example, existing technology uses pedestrian protection airbags that deploy from the raised hood onto the windshield or A-pillar. While these airbags protect pedestrians in a collision, they require a large inflation volume and obstruct the windshield, potentially affecting the driver's vision. This increases the risk of a secondary collision. Utility Model Content

[0004] One objective of this utility model is to provide an airbag device to solve the problems of existing pedestrian protection airbags having a large inflation requirement, obstructing the windshield and easily affecting the driver's vision, thus increasing the risk of secondary collisions; the second objective is to provide a vehicle.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] An airbag device includes a protective airbag and an airbag inflation assembly. The protective airbag is mounted in a front hood trim assembly of a vehicle and located in a region of the front hood trim assembly near the front pillar of the vehicle. The airbag inflation assembly is in communication with the air passage of the protective airbag. When the airbag inflation assembly is activated, it inflates the protective airbag, causing the protective airbag to eject from the front hood trim assembly and deploy along the length of the front pillar.

[0007] Based on the aforementioned technical means, the protective airbag, when deployed, can prevent pedestrians from colliding with the vehicle from hitting the front pillar, reducing physical injury to pedestrians while also allowing for a miniaturized design. Furthermore, with a simple structure that facilitates inflation and deployment, it does not obstruct the driver's view, significantly reducing the risk of secondary collisions.

[0008] Furthermore, the protective airbag includes:

[0009] The first airbag body is connected to the air passage of the airbag inflation component;

[0010] The second airbag body is connected to the air passage of the first airbag body and is set at an angle to the first airbag body;

[0011] The first airbag body, in its deployed state, covers the front pillar, and the second airbag body, in its deployed state, forms a protective surface along the height direction of the vehicle.

[0012] Based on the aforementioned technical means, the protective airbag can not only greatly reduce the physical damage caused by a pedestrian's head hitting the front pillar of a vehicle, but also prevent the pedestrian from falling from the side of the front pillar and causing secondary injury through the protective surface.

[0013] Furthermore, the first airbag body and the second airbag body are arranged vertically.

[0014] The above-mentioned technical means facilitate the shape design and processing of the protective airbag.

[0015] Furthermore, the airbag device also includes a tension cord, one end of which is connected to the front cover trim assembly and the other end of which is connected to the second airbag body to limit the second airbag body in the deployed state.

[0016] Based on the aforementioned technical means, the tension rope prevents the second airbag from flipping or being crushed under the pressure of a pedestrian being hit, thus avoiding secondary injuries caused by the pedestrian falling from the side of the front pillar. This improves the protective effect of the second airbag on pedestrians.

[0017] Furthermore, the protective airbag is made of rubber material.

[0018] Based on the above technical means, the protective airbag can be guaranteed to have good elasticity and sealing performance, as well as good corrosion resistance, thus ensuring the deployment stability of the protective airbag.

[0019] Furthermore, the airbag inflation assembly includes:

[0020] A gas generator, wherein the gas generator is connected to the air passage of the protective airbag;

[0021] A control element, which is electrically connected to the gas generator;

[0022] A signal detection element is electrically connected to the control element to transmit a collision signal to the control element, so that the control element controls the gas generator to operate based on the collision signal.

[0023] Based on the aforementioned technical means, the protective airbag can be rapidly inflated upon detection of a collision between a vehicle and a pedestrian, thus ensuring that the protective airbag fully deploys in a very short time.

[0024] A vehicle comprising the airbag device described in any one of the above utility model claims.

[0025] Based on the aforementioned technical means, the protective airbag, when deployed, can prevent pedestrians from colliding with the vehicle from hitting the front pillar, reducing physical injury to pedestrians while also allowing for a miniaturized design. Furthermore, with a simple structure that facilitates inflation and deployment, it does not obstruct the driver's view, significantly reducing the risk of secondary collisions.

[0026] Furthermore, the vehicle includes a front hood trim assembly, which includes a front hood trim piece and a trim cover. The trim cover is located in the connection area between the front hood trim piece and the front pillar, and the protective airbag is installed on the inner side of the trim cover.

[0027] The aforementioned technical means facilitate the removal and installation of the decorative cover for the airbag device, and the cover can be easily opened when the airbag inflates and deploys. This avoids damaging other difficult-to-repair structures of the vehicle, thus reducing vehicle maintenance costs.

[0028] Furthermore, the decorative cover plate is snapped and fixed to the front cover decorative piece.

[0029] According to the above-mentioned technical means, the decorative cover is easier to be opened by the protective airbag, and the decorative cover can be easily removed from the front cover trim, thereby further reducing the vehicle's maintenance costs.

[0030] Furthermore, the decorative cover is made of a soft rubber material.

[0031] According to the above-mentioned technical means, the decorative cover has a certain elasticity and can easily return to its initial shape after being pushed open by the protective airbag, thereby improving the reusability of the decorative cover and further reducing the maintenance cost of the vehicle.

[0032] The beneficial effects of this utility model are:

[0033] The protective airbag in this invention, when deployed, can prevent pedestrians from colliding with the vehicle and hitting the front pillar, reducing pedestrian injury while also allowing for a compact design. Furthermore, its simple structure facilitates inflation and deployment without obstructing the driver's view, significantly reducing the risk of secondary collisions. Attached Figure Description

[0039] The embodiments of this utility model will be described below with reference to the accompanying drawings and preferred embodiments. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. This utility model can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this utility model. It should be understood that the preferred embodiments are only for illustrating this utility model and not for limiting the scope of protection of this utility model.

[0040] It should be noted that the illustrations provided in the following embodiments are only schematic representations of the basic concept of the present invention. Therefore, the drawings only show the components related to the present invention and are not drawn according to the number, shape and size of the components in actual implementation. In actual implementation, the form, quantity and proportion of each component can be arbitrarily changed, and the layout of the components may also be more complex.

[0041] With the development of vehicle technology, the automotive industry is paying increasing attention to and emphasizing pedestrian protection. In particular, because vehicle body structures require high rigidity and crashworthiness, the high-strength structure of the vehicle's A-pillar significantly increases the risk of severe head injuries to pedestrians in the event of a collision.

[0042] Currently, pedestrian protection airbags are a widely used method of pedestrian protection. For example, existing technology uses pedestrian protection airbags that deploy from the raised hood onto the windshield or A-pillar. While these airbags protect pedestrians in a collision, they require a large inflation volume and obstruct the windshield, potentially affecting the driver's vision. This increases the risk of a secondary collision.

[0043] Based on the aforementioned technical problems, this utility model is proposed. This utility model provides an airbag device and a vehicle. The airbag device may include a protective airbag 1 and an airbag inflation assembly 2. The protective airbag 1 is installed in the front hood trim assembly 4 of the vehicle and is located in the area of ​​the front hood trim assembly 4 near the front pillar 5 of the vehicle. The airbag inflation assembly 2 is connected to the protective airbag 1 via an air passage. When the airbag inflation assembly 2 is working, it inflates the protective airbag 1, causing the protective airbag 1 to pop out from the front hood trim assembly 4 and deploy along the length of the front pillar 5. When deployed, the protective airbag 1 can prevent pedestrians from colliding with the vehicle from hitting the front pillar 5, reducing physical injury to pedestrians while also allowing for a miniaturized design. Furthermore, with a simple structure that facilitates inflation and deployment, it does not obstruct the driver's view, significantly reducing the risk of secondary collisions.

[0044] Reference Figure 1-4 This utility model embodiment provides an airbag device that may include a protective airbag 1 and an airbag inflation assembly 2. The protective airbag 1 is installed in the front hood trim assembly 4 of a vehicle and is located in the area of ​​the front hood trim assembly 4 near the front pillar 5 of the vehicle. The airbag inflation assembly 2 is in air passage communication with the protective airbag 1. When the airbag inflation assembly 2 is in operation, it inflates the protective airbag 1, and the protective airbag 1 pops out from the front hood trim assembly 4 and deploys along the length direction of the front pillar 5.

[0045] In this embodiment of the invention, the front hood trim assembly 4 refers to a combination of components used for decoration and protection of the front of the vehicle. For example, it may include, but is not limited to, the front hood trim piece 41, the front hood outer panel, and bumper trim strips, etc. The protective airbag 1 is embedded within the front hood trim assembly 4 and located near the vehicle's front pillar 5 (also referred to as the A-pillar). The front pillar 5 is located on both sides of the vehicle's windshield and connects the front bulkhead and roof of the vehicle. It serves as a structural support between the front of the vehicle and the passenger compartment.

[0046] The airbag inflator 2 is connected to the air passage of the protective airbag 1. The airbag inflator 2 inflates the protective airbag 1, allowing for rapid inflation of the airbag 1 when the airbag inflator 2 is operational. During inflation and deployment, the protective airbag 1 pushes open the front hood trim assembly 4 and deploys along the length of the front pillar 5. The length of the front pillar 5 can be from the front of the vehicle body to the roof. Thus, the deployed airbag 1 structurally covers the front pillar 5. In the event of a collision between a pedestrian and the vehicle, the deployed airbag 1 acts as a buffer against the impact force at the front pillar 5, reducing the severity of head injuries caused by direct impact to the front pillar 5.

[0047] Furthermore, when deployed, the protective airbag 1 only needs to cover a portion of the front pillar 5, thus reducing its size and inflation requirements. This improves the deployment efficiency of the airbag 1. Moreover, its simple structure facilitates inflation and deployment without obstructing the driver's view, significantly reducing the risk of secondary collisions.

[0048] In one optional embodiment of the utility model, referring to Figure 2 and Figure 3 As shown, the protective airbag 1 may include a first airbag body 11 and a second airbag body 12. The first airbag body 11 is connected to the airbag inflation assembly 2 via an air passage. The second airbag body 12 is connected to the first airbag body 11 via an air passage and is angled relative to the first airbag body 11. When deployed, the first airbag body 11 covers the front pillar 5, and the second airbag body 12, when deployed, forms a protective surface along the height direction of the vehicle.

[0049] In this embodiment of the invention, the first airbag body 11 and the second airbag body 12 are angled together. This can be understood as the first airbag body 11 in its deployed state and the second airbag body 12 in its deployed state having a certain angle between them. For example, the angle can be greater than 0 and less than or equal to 90 degrees. The first airbag body 11 in its deployed state can structurally cover the front pillar 5. In the event of a collision between a pedestrian and a vehicle, the deployed first airbag body 11 can buffer the impact force on the pedestrian at the front pillar 5, reducing the degree of physical injury caused by the pedestrian's head directly impacting the front pillar 5.

[0050] When deployed, the second airbag body 12 forms a protective surface along the vehicle's height. This can be understood as the second airbag body 12 being taller than the first airbag body 11, thus creating a protective surface based on the height difference between them. This provides lateral protection to pedestrians impacting the first airbag body 11, preventing them from falling from the side of the front pillar 5 and sustaining secondary injuries.

[0051] When the airbag inflation assembly 2 is in operation, it inflates the first airbag body 11, which is connected to it by an air passage, and simultaneously inflates the second airbag body 12, which is also connected to the first airbag body 11 by an air passage. The air passage between the airbag inflation assembly 2 and the first airbag body 11 can be formed through connecting pipes, connecting interfaces, or other devices. In some embodiments, the first airbag body 11 and the second airbag body 12 can be partially sealed at the contact points using sealant to achieve air passage connection. Those skilled in the art can also determine suitable air passage connection methods according to actual design requirements, and no further limitations are imposed here.

[0052] In one optional embodiment of the utility model, the first airbag body 11 and the second airbag body 12 are arranged vertically.

[0053] In this embodiment of the invention, the first airbag body 11 and the second airbag body 12 are arranged perpendicularly, which can be understood as the included angle between the first airbag body 11 and the second airbag body 12 being 90 degrees. That is, the first airbag body 11 and the second airbag body 12 form an L-shaped structure. Taking the width direction of the vehicle as a reference, the second airbag body 12 is located on one side of the first airbag body 11 along the width direction (the side of the first airbag body 11 away from the windshield). Therefore, the L-shaped structure of the protective airbag 1 facilitates its processing and reduces its production cost.

[0054] In one optional embodiment of the utility model, referring to Figure 2 and Figure 3 As shown, the airbag device also includes a tension rope 3, one end of which is connected to the front cover decoration assembly 4 and the other end is connected to the second airbag body 12 to limit the second airbag body 12 in the deployed state.

[0055] In this embodiment of the invention, the airbag device may further include a tension cord 3, which may be made of an elastic material, for example, a wide strip structure. One end of the tension cord 3 is connected to the front cover trim assembly 4, and the other end is connected to the second airbag body 12. For example, one end of the tension cord 3 may be provided with a fixing ring, which is bolted to the front cover trim assembly 4 and threadedly connected to it, thus fixing the tension cord 3 to the front cover trim assembly 4. The other end of the tension cord 3 may be connected to the second airbag body 12 by sewing or other means.

[0056] When both the first airbag body 11 and the second airbag body 12 are in the deployed state, the tensioning rope 3 is located above the deployed first airbag body 11. As the first airbag body 11 and the second airbag body 12 deploy, the tensioning rope 3 extends and tightens, with the tightening direction of the tensioning rope 3 pointing inwards towards the front pillar 5 along the width direction of the vehicle. This allows for positional control of the deployed second airbag body 12. For example, the tensioning rope 3 maintains an L-shaped distribution between the deployed first airbag body 11 and the deployed second airbag body 12. This prevents the second airbag body 12 from overturning or being crushed under the pressure of a pedestrian being hit, thus avoiding secondary injuries caused by the pedestrian falling from the side of the front pillar 5. This improves the protective effect of the second airbag body 12 on pedestrians.

[0057] In one optional embodiment of the utility model, the protective airbag 1 is made of rubber material.

[0058] In this embodiment of the invention, the first airbag body 11 and the second airbag body 12 can be made of rubber material. A protective airbag 1 made of rubber material ensures that it has good elasticity and sealing properties, as well as good corrosion resistance, thus guaranteeing the deployment stability of the protective airbag 1.

[0059] In one optional embodiment of the utility model, referring to Figure 4 As shown, the airbag inflation assembly 2 may include a gas generator 21, a control element 22, and a signal detection element 23. The gas generator 21 is connected to the air passage of the protective airbag 1. The control element 22 is electrically connected to the gas generator 21. The signal detection element 23 is electrically connected to the control element 22 to transmit a collision signal to the control element 22, so that the control element 22 controls the gas generator 21 to operate according to the collision signal.

[0060] In this embodiment of the invention, the protective airbag 1, the gas generator 21, the control element 22, and the signal detection element 23 can constitute an airbag system. The signal detection element 23 can be a sensor, for example, it can be one of the following types, including but not limited to: an acceleration sensor, a collision sensor, etc. The signal detection element 23 is used to detect relevant collision signals from impacts with pedestrians, cyclists, etc. The signal detection element 23 transmits the detected collision signals to the control element 22. The control element 22 can be an Electronic Control Unit (ECU).

[0061] The control element 22 determines whether the protective airbag 1 needs to be deployed based on the signal threshold corresponding to the sensing signal. If the protective airbag 1 needs to be deployed, the control element 22 controls the gas generator 21 to start working. The chemical substances in the gas generator 21 will rapidly undergo a combustion reaction under the action of the electric ignition device installed in the gas generator 21, producing some harmless gases that fill the protective airbag 1, thereby enabling the protective airbag 1 to deploy quickly. In some embodiments, both the gas generator 21 and the control element 22 can be installed on the inner side of the fender 6.

[0062] In some implementations, refer to Figure 4 As shown, if the signal detection element 23 is a collision sensor, it can be installed on the front bumper 7 of the vehicle. When the vehicle collides with a pedestrian or cyclist, the signal detection element 23 transmits a sensing signal to the control element 22. If the control element 22 detects that the sensing signal is greater than a preset collision threshold, it activates the gas generator 21. The chemical substances in the gas generator 21 will rapidly undergo a combustion reaction under the action of the electric ignition device installed in the gas generator 21, producing some harmless gases that fill the protective airbag 1, thereby causing the protective airbag 1 to deploy rapidly.

[0063] In summary, this utility model discloses an airbag device, which includes a protective airbag 1 and an airbag inflation assembly 2. The protective airbag 1 is installed in the front hood trim assembly 4 of a vehicle and is located in the area of ​​the front hood trim assembly 4 near the front pillar 5 of the vehicle. The airbag inflation assembly 2 is connected to the protective airbag 1 via an air passage. When the airbag inflation assembly 2 is working, it inflates the protective airbag 1, causing the protective airbag 1 to pop out from the front hood trim assembly 4 and deploy along the length of the front pillar 5. When deployed, the protective airbag 1 can prevent pedestrians from colliding with the vehicle from hitting the front pillar 5, reducing physical injury to pedestrians while also allowing for a miniaturized design. Furthermore, with a simple structure that facilitates inflation and deployment, it does not obstruct the driver's view, significantly reducing the risk of secondary collisions.

[0064] Reference Figure 1 , Figure 2 , Figure 3 as well as Figure 4 As shown, this utility model embodiment also provides a vehicle, which may include the airbag device as described in any of the above utility model embodiments.

[0065] In this embodiment of the invention, the protective airbag 1, when deployed, can prevent pedestrians from colliding with the vehicle from hitting the front pillar 5, reducing physical injury to pedestrians while also allowing for a smaller size design. Furthermore, with a simple structure that facilitates inflation and deployment, it does not obstruct the driver's view, significantly reducing the risk of secondary collisions and improving the overall pedestrian protection score in vehicle collisions.

[0066] In one optional embodiment of the utility model, referring to Figure 1 As shown, the vehicle includes a front hood trim assembly 4, which includes a front hood trim piece 41 and a trim cover 42. The trim cover 42 is located in the connection area between the front hood trim piece 41 and the front pillar 5, and the protective airbag 1 is installed on the inner side of the trim cover 42.

[0067] In this embodiment of the invention, the front grille trim 41 is installed on the front grille of the vehicle body and is used to beautify the appearance and enhance the overall styling of the vehicle. The side of the front grille trim 41 is usually adjacent to or connected to the fender 6 of the vehicle. The side edge of the front grille trim 41 is close to the bottom of the front pillar 5. The fender 6 is installed above the front wheels on both sides of the vehicle and is used to connect the front bumper 7 and the door. The decorative cover plate 42 is connected to the front grille trim 41 and serves as a plate-shaped component for decoration, protection, or concealment of the internal structure. For example, the decorative cover plate 42 is located in the connection area between the front grille trim 41 and the front pillar 5 (or it can be seen as the bottom corner of the windshield). The protective airbag 1 is embedded in the decorative cover plate 42. Thus, when the protective airbag 1 is deployed, the relatively small decorative cover plate 42 can be pushed open and quickly deployed along the length of the front pillar 5. This facilitates the removal and installation of the decorative cover plate 42 to install the airbag device. Furthermore, during vehicle repairs, it will not damage other difficult-to-repair structures of the vehicle, thus reducing the vehicle's repair costs.

[0068] In one optional embodiment of the utility model, the decorative cover plate 42 is snapped and fixed to the front cover decorative member 41.

[0069] In this embodiment of the invention, when the decorative cover 42 and the front hood trim 41 are fixed by a snap-fit ​​mechanism, the decorative cover 42 is more easily opened by the protective airbag 1. Furthermore, when the decorative cover 42 pops off the front hood trim 41, the integrity of the connection structure between the decorative cover 42 and the front hood trim 41 is maintained. This not only facilitates the removal and installation of the decorative cover 42 from the front hood trim 41, but also further reduces the vehicle's maintenance costs.

[0070] In one optional embodiment of the utility model, the decorative cover plate 42 is made of a soft rubber material.

[0071] In this embodiment of the invention, the soft rubber material refers to a type of material that is soft and elastic. For example, soft rubber materials may include, but are not limited to, silicone rubber, natural rubber, synthetic rubber, and thermoplastic elastomers. Therefore, the decorative cover 42 made of soft rubber material has a certain degree of elasticity. After being deployed by the protective airbag 1, it easily returns to its initial shape and will not be damaged after being ejected and dropped. This improves the reusability of the decorative cover 42 and further reduces the vehicle's maintenance costs.

[0072] In summary, this utility model discloses a vehicle that may include a protective airbag 1 and an airbag inflation assembly 2. The protective airbag 1 is installed in the front hood trim assembly 4 of the vehicle and is located in the area of ​​the front hood trim assembly 4 near the front pillar 5 of the vehicle. The airbag inflation assembly 2 is in air passage communication with the protective airbag 1. When the airbag inflation assembly 2 is working, it inflates the protective airbag 1, causing the protective airbag 1 to pop out from the front hood trim assembly 4 and deploy along the length of the front pillar 5. When deployed, the protective airbag 1 can prevent pedestrians from colliding with the vehicle from hitting the front pillar 5, reducing physical injury to pedestrians while also allowing for a miniaturized design. Furthermore, with a simple structure that facilitates inflation and deployment, it does not obstruct the driver's view, greatly reducing the risk of secondary collisions.
