Automobile safety air curtains are widely used in modern automobiles. The automobile safety air curtain is also called a head safety air bag, and pops up to cover the automobile window during collision, so that the effect of protecting passengers is achieved. The main function of the side air curtain is to protect the head and the face of the passenger. When the lateral acceleration is larger than the normal value and reaches a dangerous value, the detonation is controlled. The car has good personnel protection function for serious accidents such as side collision, car rollover and the like.
Currently, in the event of a small angle collision, the head of the occupant can slam hard against the a-pillar of the vehicle, risking injury to the face and head of the occupant. After the side air curtain is exploded, the A column is broken or falls off from the A column sheet metal, so that the head of a passenger is secondarily injured.
The main technical disadvantages are as follows:
1. the A column inner decorative plate blocks and interferes with the safe air curtain blasting;
2. the A column inner decoration plate impacts the inner decoration plate after the safety air curtain is blasted, so that the A column inner decoration plate is broken to generate fragments or splashes;
3. the anti-falling buckle of the A column inner decorative plate is invalid after being impacted, and the A column inner decorative plate falls off integrally.
Disclosure of Invention
In view of the above, the present utility model provides an a-pillar trim panel, which ensures that the a-pillar trim panel is not broken and splashed after blasting, guides the air curtain blasting, and reduces the resistance of the a-pillar trim panel to the safe air curtain blasting.
The utility model provides an A-column interior plaque which adopts the following technical scheme:
the utility model provides an interior plaque of A post, includes the interior plaque body of A post, the weakening groove has been seted up on the interior plaque body of A post, the interior plaque body of A post is overturned along the weakening groove after the air curtain blasting of interior plaque body of A post.
Optionally, the weakening groove is formed in an inner side stress concentration area of the A column inner decorative plate body.
Optionally, the weakening groove comprises a plurality of weakening units continuously arranged along the length direction of the a-pillar trim panel body.
Optionally, the cross section of the weakening unit is an L-shaped groove.
Optionally, the L-shaped groove comprises a transverse groove and a vertical groove perpendicular to the transverse groove.
Optionally, an anti-falling buckle is arranged on the A column interior trim panel body.
Optionally, the weakening groove is formed in the rounded corner of the A-pillar inner decorative plate.
Optionally, the longitudinal section of the weakening unit is U-shaped.
Optionally, the anti-falling buckle is located above the weakening groove.
Optionally, the weakening groove is located in a position below the air curtain.
In summary, the present utility model includes at least one of the following beneficial technical effects:
1. after the weakening groove is added, the normal overturning of the part of the A column inner decorative plate body along the weakening groove position according to the blasting direction is ensured, and the blocking of the air curtain blasting by the A column inner decorative plate is avoided;
2. after the weakening groove is added, the integrity and the no fragments of the A column inner decorative plate body after the air curtain blasting are ensured, and the generation of blasting splashes is avoided;

Detailed Description
The utility model is described in further detail below with reference to fig. 1-2.
The embodiment of the utility model discloses an A-pillar inner decoration board.
Referring to fig. 1 and 2, an a post interior decoration board includes an a post interior decoration board body 1, offer weakening groove 2 on the a post interior decoration board body 1, a post interior decoration board body 1 overturns along weakening groove 2 after the air curtain 5 of a post interior decoration board body 1 explodes, after having set up weakening groove 2, effectively guarantee that an post interior decoration board body 1 part is normally overturned along weakening groove 2 position according to the blasting direction, effectively avoid an post interior decoration board body 1 to block air curtain 5 blasting, effectively guarantee that an post interior decoration board body 1 is complete to have the piece after air curtain 5 blasting, avoid blasting splatter to produce.
The weakening groove 2 is formed in the inner side stress concentration area of the A column inner decorative plate body 1, and in the embodiment, the anti-falling buckle 4 is located above the weakening groove 2, and the weakening groove 2 is located at the lower position of the air curtain 5. The weakening groove 2 is formed at the round corner of the A-pillar inner decorative plate body 1. The weakening groove 2 includes a plurality of weakening units 3 continuously provided along the longitudinal direction of the a-pillar trim panel body 1, and in this embodiment, the cross section of the weakening unit 3 is an L-shaped groove, and the longitudinal section of the weakening unit 3 is U-shaped.
The L-shaped groove comprises a transverse groove 31 and a vertical groove 32 perpendicular to the transverse groove 31, and a plurality of L-shaped grooves are continuously formed along the length direction of the A-pillar inner decorative plate body 1, and specifically, 5L-shaped grooves are formed.
The anti-falling buckle 4 is arranged on the A-pillar interior trim panel body 1, so that the A-pillar interior trim panel body 1 is effectively ensured to completely fall off from the A-pillar metal plate under the protection of the anti-falling buckle 4. The weakening groove 2 is formed in the stress concentration area on the inner side of the A column interior trim panel body 1, so that the A column plays a role in airbag blasting, the A column interior trim panel body 1 is effectively ensured to normally overturn according to the weakening line after the air curtain 5 is blasted out, and space exists for the air curtain 5 to be blasted out from the A column; the inner decoration plate effectively ensures that the A column releases internal stress after being subjected to huge impact after the air curtain 5 is blasted, and ensures that the A column inner decoration plate body 1 is not broken and splashed after being blasted, so that passengers are scratched.
