When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0034] The present invention provides an airbag anti-flying-off device and a vehicle, wherein the airbag anti-flying-off device comprises an instrument panel 50, a lower mounting plate 10, a central mounting plate 30, an airbag plate 20 and an anti-flying-off component 40, wherein the lower mounting plate 10 and the central mounting plate 30 are arranged at the bottom of the instrument panel 50 opposite to each other; one end of the airbag plate 20 is connected to the lower mounting plate 10, and the other end is connected to the central mounting plate 30; a through hole 21 is provided on the airbag plate 20, one end of the anti-flying-off component 40 is arranged on the lower mounting plate 10 and / or the central mounting plate 30, and the other end of the anti-flying-off component 40 is penetrated through the through hole 21 and connected to the airbag plate 20.

[0035] Please refer to Figure 1 In general, the lower mounting plate 10 is mounted at the bottom of the instrument panel 50 and is located at the outermost position, and the central mounting plate 30 is mounted at a position close to the center of the bottom of the instrument panel 50. Both ends of the airbag panel 20 are connected to the lower mounting plate 10 and the central mounting plate 30, respectively. For example, a CLIP structure is used for connection.

[0036] In addition, the anti-fly-off component 40 is provided on one side where the lower mounting plate 10 is connected to the airbag plate 20 . The anti-fly-off component 40 can be connected by bonding, clamping or the like.

[0037] There are multiple anti-fly-off components 40, and the anti-fly-off components 40 can be installed on the lower mounting plate 10, or on the central mounting plate 30, or on both.

[0038] In addition, multiple anti-fly-off components 40 can be installed simultaneously on the mounting plate and / or the central mounting plate 30, and multiple anti-fly-off components 40 are arranged along the edges of the lower mounting plate 10 and / or the central mounting plate 30; the number of the perforations 21 is consistent with the number of the anti-fly-off components 40 and are arranged one-to-one on the airbag plate 20.

[0039] As an embodiment, one end of the anti-fly-off component 40 can be installed on the lower mounting plate 10 and / or the central mounting plate 30, and the other end adopts an adhesive with an adhesive effect. A flexible connection method is adopted between the adhesive and the lower mounting plate 10 and / or the central mounting plate 30, so that when flying off occurs, the flexible structure can buffer the deformation of the airbag plate 20, and the bonding method can prevent the lower mounting plate 10 and / or the central mounting plate 30 from maintaining connection with the airbag plate 20, thereby preventing flying off.

[0040] As another example, please refer to Figure 2 and Figure 3 The anti-fly-off assembly 40 includes a connecting rod 41 and a grab hook 42, one end of the connecting rod 41 is connected to the lower mounting plate 10 and / or the central mounting plate 30; the grab hook 42 is arranged on the other end of the connecting rod 41, and the grab hook 42 is used to grab the airbag panel 20 when the airbag panel 20 flies off.

[0041] The connecting rod 41 is passed through the through hole 21. When the connecting rod 41 flies off, the lower mounting plate 10 or the central mounting plate 30 can move on the connecting rod 41 to play a buffering role. When it moves to the end of the connecting rod 41, it will be hooked by the grab hook 42 to prevent it from being separated from the airbag plate 20 and avoid flying off.

[0042] Specifically, the grab hook 42 and the connecting rod 41 are arranged in a stepped shape, and the height of the grab hook 42 is higher than the connecting rod 41. When the lower mounting plate 10 or the central mounting plate 30 moves to the end of the connecting rod 41 after flying off, it will abut against the step structure 43 between the connecting rod 41 and the grab hook 42.

[0043] In normal assembly, the catch hook 42 protrudes upward along the connecting rod 41 to form a stepped structure 43. The catch hook 42 is located higher, so as to block the lower mounting plate 10 or the central mounting plate 30 moving to the end.

[0044] In this embodiment, the cross-sectional area of ​​the connecting rod 41 is adapted to the area of ​​the through hole 21, thereby ensuring that the lower mounting plate 10 or the central mounting plate 30 will not shake when moving on the connecting rod 41 after being detached from the instrument panel 50, thereby playing a limiting role and further improving safety.

[0045] Furthermore, the hook 42 has a guide portion 44 on the side facing away from the connecting rod 41, and the thickness of the hook 42 is gradually reduced in the direction away from the connecting rod 41 to form the guide portion 44. It can be understood that since the cross-sectional area of ​​the connecting rod 41 is adapted to the area of ​​the through hole 21, in order to ensure that the raised hook 42 can be smoothly inserted into the through hole 21, the guide portion 44 is provided on the other side of the hook 42.

[0046] The guide portion 44 is inclined, and the thickness of the hook 42 gradually decreases toward the side away from the connecting rod 41, that is, the thickness of the portion where the hook 42 first contacts the through hole 21 is the lowest, so as to ensure that the hook 42 can enter the through hole 21. The surface of the guide portion 44 is smooth, so that the hook 42 can smoothly pass through the through hole 21.

[0047] Further, the thickness of the portion of the connecting rod 41 close to the hook 42 is smaller than the thickness of the portion of the connecting rod 41 close to the lower mounting plate 10 or the central mounting plate 30. The smaller thickness allows a certain elastic deformation to further improve the convenience of the hook 42 passing through the through hole 21.

[0048] According to the technical solution of the utility model, when the knee airbag is deployed after a collision of the vehicle, the airbag plate 20 is subjected to a huge force, and uncontrollable deformation and shaking occur, resulting in the lower mounting plate 10 and / or the central mounting plate 30 flying off from the airbag plate 20. When the lower mounting plate 10 and / or the central mounting plate 30 fly off, the lower mounting plate 10 and / or the central mounting plate 30 are clamped in the through hole 21 through the anti-flying-off component 40, and the anti-flying-off component 40 can hold it tightly, thereby playing the role of preventing the mounting plate from flying off, reducing secondary damage to the driver, and improving driving safety performance.

[0049] Furthermore, when the grab hook 42 is connected to the lower mounting plate 10, there is a gap between the grab hook 42 and the lower mounting plate 10; when the anti-fly-off assembly 40 is also installed on the central mounting plate 30, when the grab hook 42 is connected to the central mounting plate 30, there is a gap between the grab hook 42 and the central mounting plate 30.

[0050] In this embodiment, by providing a gap, when the lower mounting plate 10 or the central mounting plate 30 is separated from the instrument panel 50, a certain buffer distance is provided to prevent the lower mounting plate 10 or the central mounting plate 30 from breaking and generating debris, thereby further improving safety.

[0051] Furthermore, the airbag panel 20 is provided with a clamping groove 62, and the lower mounting plate 10 is provided with a clamping block 61. When the airbag panel 20 is connected to the lower mounting plate 10, the clamping block 61 is clamped in the clamping groove 62. The clamping groove 62 cooperates with the clamping block 61, so that the connection strength between the lower mounting plate 10 or the central mounting plate 30 and the airbag panel 20 can be further improved.

[0052] In addition, in order to solve the above-mentioned problem, the present invention also proposes a vehicle, and the vehicle is applied with the airbag anti-flying-off device as mentioned above.

[0053] There are multiple anti-fly-off components 40, and the anti-fly-off components 40 can be installed on the lower mounting plate 10, or on the central mounting plate 30, or on both.

[0054] In addition, multiple anti-fly-off components 40 can be installed simultaneously on the mounting plate and / or the central mounting plate 30, and multiple anti-fly-off components 40 are arranged along the edges of the lower mounting plate 10 and / or the central mounting plate 30; the number of the perforations 21 is consistent with the number of the anti-fly-off components 40 and are arranged one-to-one on the airbag plate 20.

[0055] The anti-fly-off assembly 40 includes a connecting rod 41 and a grab hook 42, one end of the connecting rod 41 is connected to the lower mounting plate 10 and / or the central mounting plate 30; the grab hook 42 is arranged on the other end of the connecting rod 41, and the grab hook 42 is used to grab the airbag panel 20 when the airbag panel 20 flies off.

[0056] The connecting rod 41 is passed through the through hole 21. When the connecting rod 41 flies off, the lower mounting plate 10 or the central mounting plate 30 can move on the connecting rod 41 to play a buffering role. When it moves to the end of the connecting rod 41, it will be hooked by the grab hook 42 to prevent it from being separated from the airbag plate 20 and avoid flying off.

[0057] Specifically, the grab hook 42 and the connecting rod 41 are arranged in a stepped shape, and the height of the grab hook 42 is higher than the connecting rod 41. When the lower mounting plate 10 or the central mounting plate 30 moves to the end of the connecting rod 41 after flying off, it will abut against the step structure 43 between the connecting rod 41 and the grab hook 42.

[0058] In normal assembly, the catch hook 42 protrudes upward along the connecting rod 41 to form a stepped structure 43. The catch hook 42 is located higher, so as to block the lower mounting plate 10 or the central mounting plate 30 moving to the end.

[0059] In this embodiment, the cross-sectional area of ​​the connecting rod 41 is adapted to the area of ​​the through hole 21, thereby ensuring that the lower mounting plate 10 or the central mounting plate 30 will not shake when moving on the connecting rod 41 after being detached from the instrument panel 50, thereby playing a limiting role and further improving safety.

[0060] Furthermore, the hook 42 has a guide portion 44 on the side facing away from the connecting rod 41, and the thickness of the hook 42 is gradually reduced in the direction away from the connecting rod 41 to form the guide portion 44. It can be understood that since the cross-sectional area of ​​the connecting rod 41 is adapted to the area of ​​the through hole 21, in order to ensure that the raised hook 42 can be smoothly inserted into the through hole 21, the guide portion 44 is provided on the other side of the hook 42.

[0061] The guide portion 44 is inclined, and the thickness of the hook 42 gradually decreases toward the side away from the connecting rod 41, that is, the thickness of the portion where the hook 42 first contacts the through hole 21 is the lowest, so as to ensure that the hook 42 can enter the through hole 21. The surface of the guide portion 44 is smooth, so that the hook 42 can smoothly pass through the through hole 21.

[0062] Further, the thickness of the portion of the connecting rod 41 close to the hook 42 is smaller than the thickness of the portion of the connecting rod 41 close to the lower mounting plate 10 or the central mounting plate 30. The smaller thickness allows a certain elastic deformation to further improve the convenience of the hook 42 passing through the through hole 21.

[0063] According to the technical solution of the utility model, when the knee airbag is deployed after a collision of the vehicle, the airbag plate 20 is subjected to a huge force, and uncontrollable deformation and shaking occur, resulting in the lower mounting plate 10 and / or the central mounting plate 30 flying off from the airbag plate 20. When the lower mounting plate 10 and / or the central mounting plate 30 fly off, the lower mounting plate 10 and / or the central mounting plate 30 are clamped in the through hole 21 through the anti-flying-off component 40, and the anti-flying-off component 40 can hold it tightly, thereby playing the role of preventing the mounting plate from flying off, reducing secondary damage to the driver, and improving driving safety performance.
