Description

Technical Field

[0001] This application relates to the field of vehicle technology, and more particularly to an airbag housing assembly, an airbag assembly, a safety protection system, and a vehicle. Background Technology

[0002] In related technologies, airbag deployment typically involves the rapid release of gas through a gas generator, combined with a weakened structure at the tear seam of the trim cover, to open the cover and inflate the airbag. If the weakening line on the trim cover is too shallow, the airbag may not deploy properly; if the weakening groove is too deep, it will affect the appearance and may even compromise the strength of the trim cover, failing to meet minimum strength requirements and making it prone to damage. Summary of the Invention

[0003] The airbag housing assembly provided in this application embodiment solves at least partially the above-mentioned problems.

[0004] The first aspect of this application provides an airbag housing assembly, including an airbag housing, the airbag housing including a receiving cavity;

[0005] A decorative cover, the decorative cover being movably disposed on the airbag housing to switch between a closed state of closing the receiving cavity and an open state of opening the receiving cavity;

[0006] When the cover is in the open state, at least a portion of the cover is adapted to be located within the receiving cavity.

[0007] In some examples, the cover includes a first arcuate plate, and the airbag housing includes a second arcuate plate adapted to the first arcuate plate.

[0008] In some examples, the central angle of the first arc-shaped plate is α, where 60° ≤ α ≤ 180°.

[0009] In some examples, when the cover is in the closed state, the airbag housing assembly is generally cylindrical in shape.

[0010] In some examples, the cover is adapted to rotate about a first axis to switch between the open state and the closed state, the first axis being the central axis of the first arcuate plate.

[0011] In some examples, a drive component is also included, which is adapted to drive the cover to move to switch between the open state and the closed state.

[0012] In some examples, the drive assembly includes a motor and a reduction gear, the motor being connected to the trim cover via the reduction gear.

[0013] In some examples, the reduction mechanism includes a worm gear mechanism or a planetary gear mechanism.

[0014] In some examples, the airbag housing assembly also includes a controller for receiving an airbag assembly deployment signal and controlling the drive assembly to switch the cover to the open state.

[0015] In some examples, the cover includes a first cover and a second cover, the first cover being adapted to move in a first direction to open the airbag housing, and the second cover being adapted to move in a second direction to open the airbag housing, the first direction and the second direction being opposite.

[0016] In some examples, when the cover is in the closed state, the first cover and the second cover are arranged side by side.

[0017] In some examples, the airbag housing assembly further includes a drive assembly comprising a first drive assembly and a second drive assembly, wherein the first drive assembly is used to drive the first trim cover to move, and the second drive assembly is used to drive the second trim cover to move.

[0018] In some examples, the first drive component and the second drive component are adapted to be located at opposite ends of the length of the airbag housing.

[0019] In some examples, the first cover is adapted to rotate in a first direction to open the airbag housing, and the second cover is adapted to rotate in a second direction to open the airbag housing, wherein the rotation axes of the first cover and the second cover are the same.

[0020] A second aspect of this application provides an airbag assembly, including an airbag and an airbag housing assembly according to a first aspect, the airbag being adapted to be disposed within a receiving cavity.

[0021] A third aspect of this application provides a safety protection system, including an airbag housing assembly according to the first aspect, or this includes an airbag assembly according to the second aspect.

[0022] The fourth aspect of this application provides a vehicle including an airbag housing assembly according to the first aspect, or this includes an airbag assembly according to the second aspect, or includes a safety protection system according to the third aspect.

[0023] The airbag housing is movably mounted on the cover, allowing the airbag housing assembly to switch between a closed state (closing the receiving cavity) and an open state (opening the receiving cavity). This eliminates the need for structural weakening of the cover, ensuring the reliability and stability of the airbag housing assembly. Furthermore, since the cover is at least partially located within the receiving cavity when in the open state, the installation space required for the airbag housing assembly is reduced to some extent, improving space utilization and minimizing the risk of interference between the cover and other structures when in the open state.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0043] refer to Figures 1 to 8 As shown, an embodiment of the present invention discloses an airbag housing assembly 100, including an airbag housing 20 and a cover 10. The airbag housing 20 includes a receiving cavity 21, and the cover 10 is adapted to be movably disposed on the airbag housing 20 to switch between a closed state with the receiving cavity 21 closed and an open state with the receiving cavity 21 open.

[0044] This application achieves the opening and closing of the receiving cavity 21 through the movement of the cover 10, thereby eliminating the need for a weakening structure on the cover 10. This improves the strength of the cover 10, and the cover 10 can reliably open the receiving cavity 21, allowing the airbag to burst smoothly. The airbag housing assembly 100 of this application can improve the reliability and stability of the airbag housing assembly 100, and also enhances the aesthetics of the cover 10 to a certain extent.

[0045] In related technologies, the airbag cover switches between an open and closed state by flipping, which requires sufficient space to be reserved for the open cover, resulting in low space utilization and the risk of the cover interfering with other structures.

[0046] In some embodiments of this application, such as Figure 1As shown, when the cover 10 is in the open state, at least a portion of the cover 10 is adapted to be located within the receiving cavity 21. It is understood that "at least a portion of the cover 10 is adapted to be located within the receiving cavity 21" means that, when the cover 10 is in the open state, either partially or completely, the cover 10 may be located within the receiving cavity 21. Since the cover 10 is at least partially located within the receiving cavity 21 when in the open state, the space occupied by the cover 10 outside the airbag housing 20 is reduced, thereby at least partially reducing the installation space required for the airbag housing assembly 100, thus improving space utilization and at least reducing the risk of interference between the cover 10 and other structures when in the open state. It is understood that the cover 10, in the closed state, can switch to the open state of opening the receiving cavity 21 by moving or rotating into the receiving cavity 21, or a combination of various forms of movement.

[0047] It is understandable that the closed state refers to the state in which the cover 10 is placed over the receiving cavity 21 so that the airbag cannot fall out of the receiving cavity 21, while the open state refers to the state in which the cover 10 at least partially opens the receiving cavity 21 so that the airbag can burst and at least partially come out of the receiving cavity 21.

[0048] In some embodiments of this application, such as Figure 4 As shown, the cover 10 includes a first arcuate plate 11, and the airbag housing 20 includes a second arcuate plate 22 that is adapted to the first arcuate plate 11.

[0049] Since the cover 10 includes a first arc-shaped plate 11 and the airbag housing 20 includes a second arc-shaped plate 22 that is adapted to the first arc-shaped plate 11, the cover 10 can be rotated to move at least partially into the interior of the receiving cavity 21. At this time, the first arc-shaped plate 11 can be at least partially stacked on the inner side of the second arc-shaped plate 22. In this way, the assembly space of the airbag inside the receiving cavity 21 can be guaranteed, and the design of the drive assembly 30 for driving the cover 10 to rotate can be facilitated.

[0050] It should be noted that the cover 10 may also include other structures connected to the first arc-shaped plate 11, such as a reinforcing structure, or a structure connecting the first arc-shaped plate 11 and the transmission component. These can be designed according to requirements. The cover 10 may also be integrally formed with a portion of the transmission component. The airbag housing 20 includes a second arc-shaped plate 22. The airbag housing 20 may also include other structures connected to the second arc-shaped plate 22. These can be designed according to requirements. The first arc-shaped plate 11 is preferably disposed at least on the side of the cover 10 near the airbag housing 20, and the second arc-shaped plate 22 is preferably disposed at least on the side of the airbag housing 20 near the cover 10. In the radial direction of the first arc-shaped plate 11, the first arc-shaped plate 11 is closer to the center of the airbag housing 20 than the second arc-shaped plate 22. When the cover 10 rotates, the first arc-shaped plate 11 rotates to the side of the second arc-shaped plate 22. On the inner side, in some embodiments of this application, the outer wall of the first arc-shaped plate 11 and the inner wall of the second arc-shaped plate 22 can fit together, thus improving the closure of the airbag assembly 100 in the closed state and increasing the internal space of the airbag assembly 100 in the open state. In some embodiments of the application, a small gap may also exist between the outer wall of the first arc-shaped plate 11 and the inner wall of the second arc-shaped plate 22, thereby reducing the friction between the first arc-shaped plate 11 and the second arc-shaped plate 12 and making the rotation of the first arc-shaped plate 11 smoother.

[0051] In some embodiments of this application, combined with Figure 1 , Figure 2 and Figure 3 As shown, the central angle of the first arc-shaped plate 11 is α, where 60°≤α≤180°. It can be understood that the central angle of the first arc-shaped plate 11 refers to the central angle corresponding to the arc of the first arc-shaped plate. By ensuring that the central angle of the first arc-shaped plate 11 is between 60° and 180°, it can be guaranteed that the cover 10 can open an opening of a suitable size with a small rotation angle, ensuring that the airbag can be successfully deployed.

[0052] In some embodiments of this application, such as Figure 2 As shown, when the cover 10 is closed, the airbag housing assembly 100 is approximately cylindrical. That is, the outer periphery of the airbag housing 20 is arc-shaped, and the outer periphery of the cover 10 is also arc-shaped. When the cover 10 is closed, the outer periphery of the airbag housing assembly 100, composed of the airbag housing 20 and the cover 10, is approximately cylindrical. For airbags that are folded by rolling, designing the airbag housing assembly 100 as a cylindrical structure can save more space.

[0053] In some embodiments of this application, combined with Figure 1 , Figure 2 and Figure 3As shown, the cover 10 is adapted to rotate about a first axis to switch between an open state and a closed state, the first axis being the central axis of the first arc-shaped plate 11. By moving the cover 10 about the central axis of the first arc-shaped plate 11 to switch between the open and closed states, the space occupied by the cover 10 during movement can be further reduced, thereby further improving space utilization.

[0054] In some embodiments of this application, such as Figure 1 and Figure 2 As shown, it also includes a drive assembly 30, which is adapted to drive the cover 10 to move to switch between an open state and a closed state. By driving the cover 10 to move through the drive assembly 30, thereby opening the receiving cavity 21, it is easier to achieve more precise control over the movement of the cover 10, thereby enabling more precise control over the timing of the cover 10 opening the receiving cavity 21 and improving the reliability of the airbag housing assembly 100.

[0055] In some embodiments of this application, such as Figure 3 As shown, the drive assembly 30 includes a motor 31 and a reduction mechanism 32. The motor 31 is connected to the cover 10 via the reduction mechanism 32. Since the motor 31 is connected to the cover 10 via the reduction mechanism 32, the rotational speed of the motor 31 can be effectively controlled, thereby facilitating the control of the rotational speed of the cover 10 and reducing the minimum power requirement for the motor.

[0056] In some embodiments of this application, such as Figure 3 As shown, the reduction mechanism 32 includes a worm gear mechanism or a planetary gear mechanism. The worm gear mechanism 32 has the advantages of compact structure and large transmission ratio; the planetary gear mechanism 32 has the advantages of small size, high transmission efficiency, wide reduction range, and high precision. Taking the worm gear mechanism as an example, the rotation of the motor 31 drives the worm to rotate, thereby driving the worm wheel to rotate. The cover 10 is connected to the worm wheel via a mating key, achieving synchronous rotation with the worm wheel.

[0057] In some embodiments of this application, the airbag housing assembly 100 further includes a controller for receiving an airbag assembly deployment signal and controlling the drive assembly 30 to drive the cover 10 to switch to the open state.

[0058] Understandably, when the vehicle airbag assembly needs to deploy or when certain pre-set scenarios occur, the sensors transmit signals to the controller. The controller then sends control signals to the drive assembly 30. Upon receiving the signal from the controller, the motor 31 of the drive assembly 30 rotates. The transmission component of the drive assembly 30 converts this rotation into linear or rotational motion, driving the cover 10 to move linearly or rotate, thus switching the cover 10 between open and closed states. Understandably, the airbag deployment signal could be triggered when the vehicle is wading through water, requiring the airbag assembly to deploy to provide greater buoyancy and buy more time for occupants to escape and await rescue; or it could be triggered during a collision, requiring the airbag assembly to deploy to protect occupants or provide protection for the vehicle through the deployed airbags.

[0059] In some embodiments of this application, such as Figure 5 As shown, the cover 10 includes a first cover 12 and a second cover 13. The first cover 12 is adapted to move in a first direction to open the airbag housing 20, and the second cover 13 is adapted to move in a second direction to open the airbag housing 20. The first direction and the second direction are opposite.

[0060] By including a first cover 12 and a second cover 13 that move in opposite directions, the cover 10 can open the receiving cavity 21 more quickly, or within a limited time, the cover 10 can open the receiving cavity 21 to a larger size.

[0061] It is understandable that the first decorative cover 12 and the second decorative cover 13 may move in opposite directions to enter the airbag housing 20; or the first decorative cover 12 and the second decorative cover 13 may rotate in opposite directions to enter the airbag housing 20, such as the first decorative cover 12 rotating clockwise to enter the airbag housing 20 and the second decorative cover 13 rotating counterclockwise to enter the airbag housing 20; or other types of movement may be used, which can be designed according to actual needs.

[0062] In some embodiments of this application, such as Figure 5 and Figure 7 As shown, when the cover 10 is in the closed state, the first cover 12 and the second cover 13 are arranged side by side. The side-by-side arrangement of the first cover 12 and the second cover 13 means that the side of the first cover 12 closest to the second cover 13 is in contact with or has a small gap with the side of the second cover 13 closest to the first cover 12. In this way, when the first cover 12 and the second cover 13 are in the closed state, they can better cover the airbag housing 20. When the first cover 12 and the second cover 13 move in opposite directions to open the receiving cavity 21, the size of the opening can be larger, which makes it easier for the airbag to be deployed and inflated.

[0063] In some embodiments of this application, such as Figure 6 As shown, the airbag housing assembly 100 also includes a drive assembly 30, which includes a first drive assembly 33 and a second drive assembly 34. The first drive assembly 33 is used to drive the first cover 12 to move, and the second drive assembly 34 is used to drive the second cover 13 to move.

[0064] It is understandable that, such as Figure 4 , Figure 5 and Figure 6 As shown, the first drive assembly 33 and the second drive assembly 34 drive the first cover 12 and the second cover 13 to move respectively. That is, the first cover 12 and the second cover 13 are both connected to independent drive assemblies 30. The independent drive assemblies 30 can ensure that the two covers 10 can be flipped in different directions without interfering with each other. Moreover, by giving differentiated signal inputs to the first drive assembly 33 and the second drive assembly 34, the overall opening angle of the cover 10 can be controlled. In this way, the deployment direction and deployment state of the airbag can be controlled according to the actual working conditions to meet the environmental adaptation requirements of the airbag, such as the need to deal with vehicle wading or vehicle collision.

[0065] In some embodiments, the cover 10 can be divided into multiple parts, each of which can be opened independently to accommodate airbag deployment requirements under different collision scenarios. For example, depending on the direction and location of the collision, only a portion of the cover 10 needs to be opened, rather than the entire cover 10, to more precisely protect the passengers inside the vehicle.

[0066] In some embodiments, adjustments can be made based on factors such as the severity of the collision and the passenger's position. For example, the opening speed and extent of the cover 10 can be adjusted according to the magnitude of the collision force to provide optimal protection.

[0067] In some embodiments, the opening of the cover 10 can be intelligently controlled by combining the vehicle's sensor system and artificial intelligence technology. For example, the status of the vehicle and passengers can be monitored in real time, and intelligent adjustments and controls can be made according to the actual situation to provide the best protection.

[0068] In some embodiments, the airbag housing assembly 100 can be designed with multiple deployment modes, selecting the most suitable deployment mode according to different collision scenarios and passenger positions. For example, depending on the direction of the collision, a front, rear, or side deployment mode can be selected to provide the best protection.

[0069] In some embodiments, the cover 10 can be deployed by a drive assembly 30 and compressed gas, which can take into account factors such as deployment speed, controllability and cost to provide a more comprehensive protection effect.

[0070] In some embodiments of this application, such as Figure 5 and Figure 6 As shown, the first drive assembly 33 and the second drive assembly 34 are adapted to be disposed at opposite ends of the airbag housing 20 along its length. This facilitates the arrangement of the first drive assembly 33 and the second drive assembly 34 and avoids interference.

[0071] In some embodiments of this application, such as Figure 7 and Figure 8 As shown, the first cover 12 is adapted to rotate in a first direction to open the airbag housing 20, and the second cover 13 is adapted to rotate in a second direction to open the airbag housing 20, wherein the rotation axes of the first cover 12 and the second cover 13 are the same. The fact that the rotation axes of the first cover 12 and the second cover 13 are the same facilitates the arrangement of the airbag housing assembly 100, while simultaneously improving the stability and reliability of the airbag housing assembly 100.

[0072] In some embodiments of this application, when the cover 10 is closed, the airbag housing assembly 100 is approximately cylindrical. At this time, the rotation axes of the first cover 12 and the second cover 13 are approximately located at the central axis of the airbag housing assembly 100. The central angle of the first arc plate 11 of the first cover 12 is approximately 90°, the central angle of the first arc plate 11 of the second cover 13 is approximately 90°, and the central angle of the second arc plate 22 of the airbag housing 20 is approximately 180°. Thus, when the airbag housing assembly 100 needs to open the receiving cavity 21, the first cover 12 can rotate clockwise, and the second cover 13 can rotate counterclockwise. When the receiving cavity 21 is fully opened, the first cover 12 and the second cover 13 can be completely located within the receiving cavity 21 of the airbag housing 20, thereby maximizing the opening degree of the receiving cavity 21.
