[0025] The following describes in detail embodiments of the present application. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present application and are not to be construed as limiting the present application.

[0026] Reference below Figure 1-Figure 2A dashboard assembly 10 for a vehicle according to an embodiment of the present application is described. The dashboard assembly 10 includes a dashboard frame 11, a softening layer 12 and a leather layer 13. The dashboard frame 11 is connected to the vehicle body and is formed with a blasting area facing the airbag. The softening layer 12 is arranged on the surface of the dashboard frame 11. The softening layer 12 is respectively formed with a dense surface 121 and a sparse surface 123 on both sides in the thickness direction. One of the dense surface 121 and the sparse surface 123 is adhered to and connected to the dashboard frame 11, and the leather layer 13 is adhered to and connected to the other of the dense surface 121 and the sparse surface 123. A weakened area 1211 facing the blasting area is formed on the dense surface 121 to adapt to the dense surface 121 to break when impacted.

[0027] At present, vehicle dashboards are usually covered with 3D-Mesh materials. The mesh structure on the upper side of the 3D-Mesh material is sparse, and the mesh structure on the bottom side is dense. During normal installation, the dense side fits with the plastic frame, and the sparse side fits with the leather. When the passenger airbag explodes, the dense side breaks first along with the hard plastic frame, and the sparse side and the leather break easily afterwards. However, workers are prone to misidentifying the front and back sides during operation. When the sparse side is attached to the frame and the dense side is attached to the leather, the sparse side breaks along with the frame, and the dense side is not easy to break, resulting in the failure of the passenger airbag explosion.

[0028] like Figure 1 Specifically, the instrument panel assembly 10 may include an instrument panel frame 11, a softening layer 12 and a leather layer 13. The instrument panel frame 11 may be set on the vehicle body, and a bursting area may be formed on the instrument panel frame 11 that is opposite to the airbag, so that when the vehicle collides, the airbag can be ejected outward through the bursting area in time.

[0029] The softening layer 12 can be arranged on the surface of the instrument panel frame 11. The softening layer 12 can be made of 3D-Mesh material, and the softening layer 12 can be respectively formed with a dense surface 121 and a sparse surface 123 on both sides in the thickness direction. One of the dense surface 121 and the sparse surface 123 can be adhered to and connected to the instrument panel frame 11, and the other of the dense surface 121 and the sparse surface 123 can be adhered to and connected to the dermis layer 13. Optionally, the softening layer 12 can be fixed to the instrument panel frame 11 and the dermis layer 13 by bonding. The dense surface 121 has a higher structural strength to prevent the softening layer 12 from being easily torn, and the sparse surface 123 has better elasticity.

[0030] Furthermore, a weakened area 1211 arranged opposite to the blasting area can be formed on the dense surface 121. The weakened area 1211 can break when the dense surface 121 is impacted, so that the airbag can pop out from the dense surface 121 and play a role in safety protection. It should be noted that when the softening layer 12 is normally installed, that is, the dense surface 121 is connected to the instrument panel frame 11, and the sparse surface 123 is connected to the leather layer 13, the airbag can break the instrument panel frame 11 when it pops out, and the instrument panel frame 11 drives the dense surface 121 to break, so that the airbag can pop out smoothly. 2 is not installed normally. For example, the staff installs the softening layer 12 upside down, that is, the dense surface 121 is connected to the leather layer 13, and the sparse surface 123 is connected to the instrument panel frame 11. When the airbag is deployed, the weakened area 1211 of the dense surface 121 can be broken to tear the surface of the dense surface 121, which is easy to install and deploy the airbag. It can be understood that the weakened area 1211 can increase the weakening rate of the dense surface 121 and reduce its structural strength to facilitate the normal use of the airbag. In addition, by setting the weakened area 1211, the staff does not need to distinguish between the front and back sides during installation, which makes the operation more convenient.

[0031] In short, the instrument panel assembly 10 of the embodiment of the present application has an instrument panel frame 11, a softening layer 12 and a leather layer 13. The instrument panel frame 11, the softening layer 12 and the leather layer 13 can be arranged and connected in sequence in the thickness direction. A dense surface 121 and a sparse surface 123 can be formed on the softening layer 12. One of the dense surface 121 and the sparse surface 123 is bonded to the instrument panel frame 11, and the leather layer 13 is bonded to the other of the dense surface 121 and the sparse surface 123. A weakened area 1211 is formed on the dense surface 121. The weakened area 1211 can increase the weakening rate of the dense surface 121, reduce its breaking strength and make it easier to break when the airbag is installed and popped out, thereby avoiding the problem of the passenger airbag exploding and failing.

[0032] like Figure 2 As shown, in some embodiments of the present application, a weakening groove 122 recessed toward the interior of the softening layer 12 can be formed in the weakened area 1211. Optionally, the weakening groove 122 can be cut by a cutting knife, ultrasonically cut, or laser cut. It can be understood that the weakening groove 122 can be set on the dense surface 121 and extend toward the interior of the softening layer 12. Furthermore, the weakening groove 122 can also extend in the first direction or the second direction. The first direction can be the extension direction of the softening layer 12, or the weakening groove 122 can extend in the first direction and the second direction at the same time. This arrangement can increase the weakening rate of the dense surface 121 and reduce the fracture strength of the dense surface 121.

[0033] like Figure 2As shown, in some embodiments of the present application, the weakening grooves 122 may include a first weakening groove 1221 and a second weakening groove 1222. The first weakening groove 1221 may be configured as a plurality of grooves spaced apart in a first direction, and the second weakening groove 1222 may be configured as a plurality of grooves spaced apart in a second direction. By providing a plurality of first weakening grooves 1221 and a plurality of second weakening grooves 1222, the weakening rate of the dense surface 121 can be further increased, and the fracture strength of the dense surface 121 can be reduced. The first direction may be orthogonal to the second direction. When the airbag is deployed, the first weakening groove 1221 and the second weakening groove 1222 of the dense surface 121 can cause the surface of the dense surface 121 to tear through fracture, which is beneficial to the deployment of the installed airbag.

[0034] As Figure 2 shown, in some embodiments of the present application, a plurality of first weakening grooves 1221 may be configured as a group, and a plurality of second weakening grooves 1222 may be configured as two groups. The two groups of second weakening grooves 1222 are respectively provided at both ends of a group of first weakening grooves 1221 in the first direction. Further, at least one second weakening groove 1222 is connected to an adjacent first weakening groove 1221, that is, the first weakening groove 1221 and the second weakening groove 1222 may be arranged in an "H" shape, but not limited thereto. The first weakening groove 1221 and the second weakening groove 1222 may also be arranged in a "T" shape, an "L" shape, or a "匚" shape. Such an arrangement can make the dense surface 121 break more easily when the airbag is deployed, improving the reliability of the instrument panel assembly 10.

[0035] As Figure 2 shown, in some embodiments of the present application, the size of each first weakening groove 1221 in the first direction is L1, satisfying the relationship: 4mm ≤ L1 ≤ 6mm, that is, the size of each first weakening groove 1221 in the first direction can be any value between 4mm and 6mm. For example, the size of each first weakening groove 1221 in the first direction can be, but not limited to, 4mm, 5mm, 6mm, etc. The size of each second weakening groove 1222 in the second direction is L2, satisfying the relationship: 4mm ≤ L2 ≤ 6mm, that is, the size of each second weakening groove 1222 in the second direction can be any value between 4mm and 6mm. For example, the size of each second weakening groove 1222 in the second direction can be, but not limited to, 4mm, 5mm, 6mm, etc. By setting the first weakening groove 1221 and the second weakening groove 1222 within the above ranges respectively, the weakening rate of the dense surface 121 can be increased, its fracture strength can be reduced, and it can be more easily broken when the installed airbag is deployed.

[0036] As Figure 2As shown, in some embodiments of the present application, the minimum distance between two adjacent first weakened grooves 1221 is L3, which satisfies the relationship: 15mm≤L3≤25mm, that is, the minimum distance between two adjacent first weakened grooves 1221 can be any value between 15mm and 25mm. For example, the minimum distance between two adjacent first weakened grooves 1221 can be but not limited to 15mm, 17mm, 20mm, 23mm, 25mm, etc. The minimum distance between two adjacent second weakened grooves 1222 is L4, which satisfies the relationship: 15mm≤L3≤25mm. The relationship formula is: 15mm≤L4≤25mm, that is, the minimum distance between two adjacent second weakening grooves 1222 can be any value between 15mm and 25mm. For example, the minimum distance between two adjacent second weakening grooves 1222 can be but not limited to 15mm, 17mm, 20mm, 23mm, 25mm, etc. This setting can further improve the weakening rate of the dense surface 121, reduce the breaking strength of the dense surface 121 and make it easier to break when the airbag is installed, thereby avoiding the problem of passenger airbag explosion failure.

[0037] like Figure 2 As shown, in some embodiments of the present application, the maximum distance between the two first weakened grooves 1221 that are farthest apart in the first direction is D1, and the relationship is satisfied: 240mm≤D1≤270mm, that is, the maximum distance between the two first weakened grooves 1221 that are farthest apart in the first direction can be any value between 240mm and 270mm. For example, the maximum distance between the two first weakened grooves 1221 that are farthest apart in the first direction can be but is not limited to 240mm, 250mm, 255mm, 260mm, 270mm, etc., and the maximum distance between the two first weakened grooves 1221 that are farthest apart in the second direction can be but is not limited to 240mm, 250mm, 255mm, 260mm, 270mm, etc. The maximum distance between the two second weakened grooves 1222 is D2, satisfying the relationship: 90mm≤D2≤120mm, that is, the maximum distance between the two second weakened grooves 1222 farthest apart in the second direction can be any value between 90mm and 120mm. For example, the maximum distance between the two second weakened grooves 1222 farthest apart in the second direction can be but not limited to 90mm, 100mm, 105mm, 110m, 120mm, etc. This arrangement can ensure that the airbag can normally pop out from the dense surface 121 and play a role in safety protection.

[0038] like Figure 1As shown, in some embodiments of the present application, the depth of each first weakening groove 1221 is H1, satisfying the relationship: 1mm≤H1≤2mm, that is, the depth of each first weakening groove 1221 can be any value between 1mm and 2mm, for example, the depth of each first weakening groove 1221 can be but not limited to 1mm, 1.3mm, 1.6mm, 2mm, etc., and the depth of each second weakening groove 1222 is H2, satisfying the relationship: 1mm≤H2≤2mm, that is, the depth of each second weakening groove 1222 can be any value between 1mm and 2mm, for example, the depth of each second weakening groove 1222 can be but not limited to 1mm, 1.3mm, 1.6mm, 2mm, etc. By setting the depth of the first weakening groove 1221 and the depth of the second weakening groove 1222 within the above-mentioned ranges, the weakening rate of the dense surface 121 can be improved, its breaking strength can be reduced, and it can be more easily broken when the airbag is installed and popped out.

A dense surface 121 and a sparse surface 123 can be formed on the softening layer 12, and a weakened area 1211 is formed on the dense surface 121. The weakened area 1211 can increase the weakening rate of the dense surface 121, reduce its breaking strength and make it easier to break when the airbag is installed and popped out, thereby avoiding the problem of the passenger airbag exploding and failing, and improving the safety performance of the vehicle.
