Description

Technical Field

[0001] The present disclosure relates to the field of vehicle technology, and in particular to an A-pillar trim and a vehicle. Background Art

[0002] Side air curtains are provided on the frame structure of the vehicle. When the vehicle collides, the side air curtains will quickly inflate and stretch, thereby protecting the passengers in the vehicle. The side air curtains are arranged on the top of the frame structure of the vehicle and extend toward the front and rear of the vehicle respectively. The side air curtains extend into the A-pillar sheet metal of the vehicle. The vehicle usually installs an upper trim panel on the A-pillar sheet metal, and the upper trim panel covers the A-pillar sheet metal and the side air curtains. One side edge of the upper trim panel abuts against the A-pillar sheet metal, and the other side edge is connected to the sealing strip on the A-pillar sheet metal. When the side air curtains are inflated, the side air curtains exert a force on the upper trim panel, and the upper trim panel is deformed as a whole under the force, so that the upper trim panel is separated from the sealing strip, and the upper trim panel is deformed and moved in the direction away from the A-pillar sheet metal to open to form an opening, and the opening is used as an air curtain pop-up channel. The side air curtains pop out and expand outward through the air curtain pop-up channel to protect the passengers.

[0003] However, when the side air curtain explodes and expands, the entire upper trim panel is subjected to the impact force of the airbag, resulting in a limited opening size between the upper trim panel and the sealing strip. The limited opening size is not conducive to the popping out of the air curtain and can easily lead to the problem of failure of the side air curtain expansion and popping out. Utility Model Content

[0041] In order to more clearly understand the above-mentioned objectives, features and advantages of the present disclosure, the scheme of the present disclosure will be further described below. It should be noted that the embodiments of the present disclosure and the features in the embodiments can be combined with each other without conflict.

[0042] In the following description, many specific details are set forth to facilitate a full understanding of the present disclosure, but the present disclosure may also be implemented in other ways different from those described herein; it is obvious that the embodiments in the specification are only part of the embodiments of the present disclosure, rather than all of the embodiments.

[0043] Reference Figures 1 to 15 As shown, the disclosed embodiment provides an A-pillar trim, including a trim body 1, which is used to be installed on the A-pillar sheet metal 2 to cover the side air curtain 22 on the A-pillar sheet metal 2; a weakening groove 13 is formed on one side of the trim body 1 facing toward or away from the A-pillar sheet metal 2, and an area of ​​the trim body 1 located on the side of the weakening groove 13 away from the front of the vehicle is arranged opposite to the side air curtain 22 in the pop-up direction of the side air curtain 22, so that when the side air curtain 22 pops out, the areas of the trim body 1 located on both sides of the weakening groove 13 can rotate relative to each other.

[0044] Specifically, the vehicle A-pillar is a connecting pillar near the front of the vehicle that connects the roof and the front cabin. The front cabin of the vehicle is an area in the frame structure of the vehicle that is located near the front of the vehicle and is used to install the engine and other components; the A-pillar sheet metal 2 is a metal basic structural member inside the vehicle A-pillar, and the side air curtain 22 is arranged at the edge of the roof, and the side air curtain 22 extends at least toward the direction of the vehicle A-pillar, so that the part of the side air curtain 22 close to the front of the vehicle is located at the A-pillar sheet metal 2; the A-pillar sheet metal 2 is inclined relative to the ground, and the length direction of the A-pillar sheet metal 2 is the direction from the rear of the vehicle to the front of the vehicle. The A-pillar sheet metal 2 is connected to the roof and the front cabin at both ends in the horizontal direction, and the length direction of the trim body 1 is consistent with the length direction of the A-pillar sheet metal 2.

[0045] The A-pillar sheet metal 2 is inclined relative to the bottom surface, that is, the A-pillar sheet metal 2 has a first side edge and a second side edge relative to each other in the horizontal direction, the edge of the A-pillar sheet metal 2 close to the front of the vehicle in the horizontal direction is the first side edge, and the edge of the A-pillar sheet metal 2 away from the front of the vehicle in the horizontal direction is the second side edge, and the two side edges of the decorative panel body 1 in the horizontal direction are respectively connected to the first side edge and the second side edge of the A-pillar sheet metal 2, and a sealing strip 21 can also be optionally set at the second side edge of the A-pillar sheet metal 2, and the two side edges of the decorative panel body 1 opposite to each other in the horizontal direction are respectively connected to the first side edge and the second side edge.

[0046] The trim panel body 1 and the A-pillar sheet metal 2 can be selected to be inclined relative to the ground, a buckle can be selected to be set on the trim panel body 1, and a slot can be set on the surface of the A-pillar sheet metal 2 so that the buckle and the slot are engaged, thereby installing the trim panel body 1 on the A-pillar sheet metal 2. Of course, you can also choose to use bolts to connect the trim panel body 1 and the A-pillar sheet metal 2; the trim panel body 1 can be selected to be set on the side of the A-pillar sheet metal 2 facing the interior of the vehicle compartment, and the two side edges of the trim panel body 1 in the horizontal direction are respectively connected to the first side edge and the second side edge of the A-pillar sheet metal 2, so that the trim panel body 1 covers the side of the A-pillar sheet metal 2, and the side air curtain 22 extends between the A-pillar sheet metal 2 and the trim panel body 1, and the trim panel body 1 can cover the side air curtain 22 on the A-pillar sheet metal 2.

[0047] When the side air curtain 22 expands, it expands horizontally in a direction away from the front of the vehicle, and also expands vertically downward. When the side air curtain 22 inflates and contacts the trim body 1, it exerts a force on the trim body 1, so that the portion of the trim body 1 connected to the second side edge of the A-pillar sheet metal 2 is separated from the A-pillar sheet metal 2 under the driving force, so that the trim body 1 opens relative to the second side edge of the A-pillar sheet metal 2 to form an opening, and the side air curtain 22 pops out of the space between the A-pillar sheet metal 2 and the trim body 1 through the opening. For example Figure 1 and Figure 2 The direction indicated by the middle arrow is the pop-up direction a of the side air curtain 22. The direction of the force exerted by the side air curtain 22 on the trim body 1 is the same as the pop-up direction a. The trim body 1 is deformed and moved by the force exerted by the side air curtain 22, so that an opening is formed between the trim body 1 and the second side edge of the A-pillar sheet metal 2.

[0048] The above-mentioned side air curtain 22 is arranged at the edge of the roof of the vehicle, and the side air curtain 22 extends from the edge of the roof toward the direction of the front of the vehicle, so that the side air curtain 22 extends into the area of ​​the A-pillar sheet metal 2. When the side air curtain 22 is inflated, it needs to expand downward so that the side air curtain 22 can form protection in the side area inside the vehicle after popping out of the space between the A-pillar sheet metal 2 and the decorative panel body 1. Therefore, when the side air curtain 22 pops out, the decorative panel body 1 needs to move in the horizontal direction away from the side edge of the front of the vehicle toward the direction away from the A-pillar sheet metal 2 to form an opening, and the size of the opening needs to be sufficient for the side air curtain 22 to pass through, so that the side air curtain 22 can pop out from between the decorative panel body 1 and the A-pillar sheet metal 2 when inflated. In the process of the side air curtain 22 being inflated from the uninflated state to the inflated state, the expansion direction of the side air curtain 22 is the pop-up direction of the side air curtain 22, and the path passed by the side air curtain 22 during the expansion process is the pop-up path of the side air curtain 22.

[0049] The trim body 1 may optionally include an opening section 12 and a fixed section 11, and the opening section 12 is arranged opposite to the side air curtain 22 along the pop-up direction a of the side air curtain 22. The area of ​​the opening section 12 may be selected to be smaller than the area of ​​the area on the trim body 1 on the side of the weakened groove 13 away from the front of the vehicle. Of course, the area of ​​the opening section 12 may also be selected to be equal to the area of ​​the area on the trim body 1 on the side of the weakened groove 13 away from the front of the vehicle, that is, when the side air curtain 22 expands and contacts the trim body 1, the area where the trim body 1 contacts the side air curtain 22 is located in the area between the weakened groove 13 and the edge of the trim body 1 on the side away from the front of the vehicle.

[0050] Of course, since the side air curtain 22 also expands in multiple directions when it expands, the side air curtain 22 will also expand along the direction of the A-pillar sheet metal 2 toward the trim body 1, so that the side air curtain 22 and the area of ​​the trim body 1 located on the side of the weakened groove 13 away from the front of the car may also come into contact. However, the area on the side of the weakened groove 13 of the trim body 1 away from the front of the car receives the force in the pop-up direction when the side air curtain 22 expands, and the area on the side of the weakened groove 13 of the trim body 1 close to the front of the car receives the force along the direction of the A-pillar sheet metal 2 toward the trim body 1 when the side air curtain 22 expands, so that the directions of the forces on both sides of the weakened groove 13 of the trim body 1 are different, so that when the side air curtain 22 expands, the areas on both sides of the weakened groove 13 of the trim body 1 It can rotate relatively; and when the side air curtain 22 expands, it mainly expands in the pop-up direction, and the area on the side of the weakened groove 13 of the trim panel main body 1 away from the front of the vehicle bears most of the force when the side air curtain 22 expands, and the area on the side of the weakened groove 13 close to the front of the vehicle is subjected to a smaller force, so that the force on the area of ​​the weakened groove 13 of the trim panel main body 1 away from the front of the vehicle is greater than the force on the area of ​​the weakened groove 13 of the trim panel main body 1 close to the front of the vehicle. When the side air curtain 22 expands and causes the trim panel main body 1 to deform and move toward and away from the A-pillar sheet metal 2, the forces on both sides of the weakened groove 13 of the trim panel main body 1 are different in magnitude, so that the areas of the trim panel main body 1 on both sides of the weakened groove 13 can rotate relatively around the weakened groove 13.

[0051] The above-mentioned fixed section 11 is connected to the edge of the opening section 12, and the side edge of the fixed section 11 away from the opening section 12 in the horizontal direction is connected to the first side edge of the A-pillar sheet metal 2. When the side air curtain 22 is inflated, it contacts the opening section 12, so that the opening section 12 first receives the force applied by the side air curtain 22 when the side air curtain 22 is inflated, that is, the pop-up path of the side air curtain 22 passes through the opening section 12.

[0052] When the side air curtain 22 expands and applies force to the trim panel body 1, the force of the side air curtain 22 on the trim panel body 1 will cause the trim panel body 1 to rotate in the direction away from the A-pillar sheet metal 2, and the weakened groove 13 of the trim panel body 1 and the part of the side edge of the trim panel body 1 away from the front of the vehicle rotate around the weakened groove 13 relative to the weakened groove 13 of the trim panel body 1 and the part of the side edge of the trim panel body 1 close to the front of the vehicle in the direction away from the A-pillar sheet metal 2, thereby increasing the size of the opening formed between the trim panel body 1 and the second side edge of the A-pillar sheet metal 2 to facilitate the side air curtain 22 to pop out through the opening formed between the trim panel body 1 and the second side edge of the A-pillar sheet metal 2.

[0053] When the above-mentioned trim panel body 1 is connected to the A-pillar sheet metal 2 at one side edge away from the front of the vehicle in the horizontal direction, the trim panel body 1 is in a closed state, and the trim panel body 1 shields the side air curtain 22; when the trim panel body 1 is separated from the second side edge of the A-pillar sheet metal 2 at one side edge away from the front of the vehicle in the horizontal direction, so that an opening is formed between the trim panel body 1 and the second side edge of the A-pillar sheet metal 2, the trim panel body 1 is in an open state, and the side air curtain 22 can extend out of the space d between the trim panel body 1 and the A-pillar sheet metal 2 through the opening.

[0054] When the above-mentioned side air curtain 22 is inflated, due to the low strength at the weakened groove 13, after the opening section 12 is subjected to the force, the weakened groove 13 of the trim body 1 bends and deforms, so that the opening section 12 can rotate around the weakened groove 13 relative to the fixed section 11 in the direction away from the second side edge of the A-pillar sheet metal 2, thereby achieving the effect of expanding the size of the opening formed between the trim body 1 and the A-pillar sheet metal 2.

[0055] When the weakening groove 13 is not provided on the trim body 1, the opening section 12 and the fixed section 11 are a whole, and the relative positions of the opening section 12 and the fixed section 11 remain unchanged when the side air curtain 22 expands. The impact force of the side air curtain 22 on the trim body 1 is borne by the trim body 1 as a whole, and the deformation movement distance of the trim body 1 is limited, so that the opening size formed between the trim body 1 and the A-pillar sheet metal 2 is small, and the side air curtain 22 is not easy to pop out through the opening; after the weakening groove 13 is provided on the trim body 1, the expansion of the side air curtain 22 exerts an impact on the trim body 1 When force is applied, the weakened groove 13 weakens the strength of the trim body 1, making the weakened groove 13 of the trim body 1 easier to bend and deform, and the opening section 12 rotates around the weakened groove 13 relative to the fixed section 11 in the direction away from the A-pillar sheet metal 2, thereby increasing the spatial distance between the opening section 12 and the A-pillar sheet metal 2 and expanding the size of the opening to facilitate the side air curtain 22 to extend through the opening into the space between the trim body 1 and the A-pillar sheet metal 2, thereby ensuring that the side air curtain 22 can smoothly pop out from between the A-pillar sheet metal 2 and the trim body 1.

[0056] The above-mentioned weakened groove 13 can be selectively set on the side surface of the trim panel body 1 facing the A-pillar sheet metal 2. Of course, the weakened groove 13 can also be selected to be set on the side surface of the trim panel body 1 facing away from the A-pillar sheet metal 2. As long as the structural strength of the weakened groove 13 of the trim panel body 1 is reduced, the weakened groove 13 of the trim panel body 1 can be easily deformed, so that when the trim panel body 1 is subjected to the expansion of the side air curtain 22, the areas of the trim panel body 1 located on both sides of the weakened groove 13 can rotate relative to each other.

[0057] When the A-pillar trim provided by the embodiment of the present disclosure is used specifically, the trim main body 1 is installed on the A-pillar sheet metal 2, and the trim main body 1 covers the side air curtain 22 on the A-pillar sheet metal 2 to enhance the aesthetics of the internal structure of the vehicle and enable the trim main body 1 to protect the side air curtain 22. When the vehicle collides and the side air curtain 22 is inflated, the side air curtain 22 applies a force on the trim main body 1 away from the front of the vehicle, and the trim main body 1 receives the force applied by the side air curtain 22 and deforms in a direction away from the A-pillar sheet metal 2. During the deformation process of the trim main body 1, the weakened groove 13 of the trim main body 1 is bent and deformed, so that the part of the trim main body 1 located between the weakened groove 13 and the edge of the trim main body 1 in the horizontal direction away from the front of the vehicle rotates relative to the rest of the part in a direction away from the A-pillar sheet metal 2, so that a larger opening is formed between the edge of the trim main body 1 away from the front of the vehicle and the second side edge of the A-pillar sheet metal 2 for the side air curtain 22 to pass through, so that the side air curtain 22 can smoothly pop out of the space between the trim main body 1 and the A-pillar sheet metal 2.

[0058] The A-pillar trim provided by the embodiment of the present disclosure includes a trim body 1, which is used to be installed on the A-pillar sheet metal 2 to cover the side air curtain 22 on the A-pillar sheet metal 2, so as to improve the aesthetics of the internal structure of the vehicle and enable the trim body 1 to protect the side air curtain 22; a weakening groove 13 is formed on the trim body 1 on one side facing or facing away from the A-pillar sheet metal 2, and an area on the trim body 1 located on the side of the weakening groove 13 away from the front of the vehicle is arranged opposite to the side air curtain 22 in the pop-up direction of the side air curtain 22, so that the side air curtain 2 2 pops up, the areas of the trim body 1 located on both sides of the weakened groove 13 can rotate relatively. The structural strength of the trim body 1 at the weakened groove 13 is relatively low and it is easy to bend and deform, so that the areas of the trim body 1 located on both sides of the weakened groove 13 can rotate relatively, thereby increasing the size of the opening formed between the trim body 1 and the A-pillar sheet metal 2 after the trim body 1 is deformed and moved, so as to facilitate the side air curtain 22 to pop out of the space between the trim body 1 and the A-pillar sheet metal 2 through the opening, ensuring that the side air curtain 22 can smoothly pop out from between the A-pillar sheet metal 2 and the trim body 1.

[0059] Reference Figure 1 , Figure 2 and Figures 4 to 6 As shown, in some embodiments, the weakened groove 13 extends from the end of the trim body 1 away from the front of the vehicle toward the end of the trim body 1 close to the front of the vehicle, and the length of the weakened groove 13 is greater than the length of the side air curtain 22 located on the A-pillar sheet metal 2. In this way, the area that is easy to deform corresponding to the weakened groove 13 can cover the side air curtain 22 on the A-pillar sheet metal 2, ensuring that when the side air curtain 22 expands, the size of the opening between the trim body 1 and the A-pillar sheet metal 2 at each position in the length direction of the side air curtain 22 can allow the side air curtain 22 to pass through, so as to ensure that all the side air curtains 22 in the A-pillar sheet metal 2 can pop out through the opening formed by the trim body 1 and the A-pillar sheet metal 2.

[0060] Specifically, the A-pillar sheet metal 2 connects the roof of the vehicle and the front cabin of the vehicle, that is, the length direction of the A-pillar sheet metal 2 is the direction from the roof of the vehicle to the front cabin of the vehicle; after the trim panel body 1 is installed on the A-pillar sheet metal 2, the end of the trim panel body 1 away from the front of the vehicle is connected to the internal structure of the roof, and the end of the trim panel body 1 close to the front of the vehicle is connected to the internal instrument panel of the vehicle; the extension direction of the weakened groove 13 on the trim panel body 1 is in the same direction as the length direction of the trim panel body 1, that is, the weakened groove 13 extends along the length direction of the trim panel body 1, that is, the weakened groove 13 extends from the end of the trim panel body 1 connected to the internal structure of the roof toward the end of the trim panel body 1 connected to the instrument panel, and the length direction of the trim panel body 1 is the length direction of the weakened groove 13.

[0061] The length dimension of the above-mentioned weakening groove 13 is greater than the length dimension of the side air curtain 22 on the A-pillar sheet metal 2, and the weakening groove 13 extends from the end of the trim body 1 away from the front of the vehicle toward the end of the trim body 1 close to the front of the vehicle, that is, the end of the weakening groove 13 away from the front of the vehicle is located at the end of the trim body 1 away from the front of the vehicle, and the side air curtain 22 extends from the roof toward the front of the vehicle to between the A-pillar sheet metal 2 and the trim body 1, and the length of the weakening groove 13 is greater than the length dimension of the side air curtain 22 between the A-pillar sheet metal 2 and the trim body 1, that is, the weakening groove 13 on the trim body 1 can cover the side air curtain 22 located between the A-pillar sheet metal 2 and the trim body 1.

[0062] When the side air curtain 22 is inflated, the trim body 1 is deformed in the direction away from the A-pillar sheet metal 2, and the area between the weakened groove 13 and the side edge of the trim body 1 away from the front of the vehicle is deformed and rotated relative to the area between the side edge of the trim body 1 close to the front of the vehicle and the weakened groove 13 in the direction away from the A-pillar sheet metal 2, so as to ensure that an opening is formed between the side edge of the trim body 1 away from the front of the vehicle and the second side edge of the A-pillar sheet metal 2, and the dimensions of the opening at each position along the length direction of the side air curtain 22 are suitable for the passage of the side air curtain 22, so as to ensure that all the side air curtains 22 on the A-pillar sheet metal 2 can pop out through the opening formed between the trim body 1 and the A-pillar sheet metal 2.

[0063] Reference Figures 4 to 6 As shown, in some embodiments, there is a first spacing between the edge of the weakened groove 13 near the front of the vehicle and the edge of the side air curtain 22 near the front of the vehicle, and the first spacing is greater than or equal to 10 mm. In this way, the edge of the weakened groove 13 exceeds the edge of the side air curtain 22, so that the weakened groove 13 on the trim body 1 can correspond to the side air curtain 22 in the length direction of the trim body 1, ensuring that the size of each position of the opening formed between the trim body 1 and the A-pillar sheet metal 2 is suitable for the side air curtain 22 to pass through, thereby improving the stability of the pop-up operation of the side air curtain 22.

[0064] Specifically, the first spacing can be selected to be 10 mm, and of course, the first spacing can also be selected to be greater than 10 mm, that is, the difference between the length dimension of the weakened groove 13 and the length dimension of the side air curtain 22 on the A-pillar sheet metal 2 is greater than or equal to 10 mm. When the first spacing is less than 10 mm, the distance between the end of the weakened groove 13 close to the front of the vehicle and the end of the side air curtain 22 close to the front of the vehicle is relatively close, that is, the trim body 1 at the end of the weakened groove 13 close to the front of the vehicle is difficult to deform, and it is easy to make the side air curtain 22 expand. The size of the opening between the trim body 1 and the A-pillar sheet metal 2 corresponding to the end of the weakened groove 13 close to the front of the vehicle is small, which affects the effect of the side air curtain 22 popping out through the opening at the end.

[0065] Reference Figure 1 and Figure 2 As shown, in some embodiments, the trim body 1 includes a fixed section 11 and an opening section 12; one side of the fixed section 11 is connected to the opening section 12, a weakened groove 13 is formed at the connection between the fixed section 11 and the opening section 12, a side of the fixed section 11 away from the opening section 12 is connected to an edge of the A-pillar sheet metal 2 close to the front of the vehicle, a side of the opening section 12 away from the fixed section 11 is connected to an edge of the A-pillar sheet metal 2 away from the front of the vehicle, and a projection of the side air curtain 22 along the pop-up direction is located within the projection of the opening section 12 along the pop-up direction. Such arrangement enables the opening section 12 to fully receive the force applied by the side air curtain 22, and the weakened groove 13 is deformed so that the opening section 12 can rotate relative to the fixed section 11 in the direction away from the A-pillar sheet metal 2. At the same time, the force of the opening section 12 is transmitted to the fixed section 11, so that the fixed section 11 can also deform and move in the direction away from the A-pillar sheet metal 2, ensuring that the opening section 12 can move a sufficient distance relative to the A-pillar sheet metal 2, so that the weakened groove 13 and the opening section 12 cooperate with each other to increase the size of the opening formed between the trim body 1 and the A-pillar sheet metal 2, so that the size of the opening can allow the side air curtain 22 to pass smoothly.

[0066] The side air curtain 22 is arranged along Figure 1 and Figure 2The projection of the pop-up direction a on the plane perpendicular to the ground is located inside the projection of the opening section 12 along the pop-up direction a, that is, the area in contact with the trim panel body 1 when the side air curtain 22 is inflated can be located in the opening section 12, so that the force generated by the expansion of the side air curtain 22 can all act on the opening section 12, and the opening section 12 can fully rotate around the weakened groove 13 relative to the fixed section 11 in the direction away from the A-pillar sheet metal 2 to ensure the size of the opening formed between the trim panel body 1 and the A-pillar sheet metal 2; the opening section 12 can fully receive the force applied by the side air curtain 22, so that the forces on both sides of the weakened groove 13 on the trim panel body 1 are unequal, so as to implement the weakened groove 13 on the trim panel body 1 to fully bend and deform, so as to increase the distance that the opening section 12 moves relative to the A-pillar sheet metal 2, so that the weakened groove 13 and the opening section 12 cooperate to increase the size of the opening formed between the trim panel body 1 and the A-pillar sheet metal 2, so that the size of the opening can allow the side air curtain 22 to pass smoothly.

[0067] The weakened groove 13 of the above-mentioned trim body 1 and the portion of the edge of one side of the trim body 1 away from the front of the vehicle in the horizontal direction can be selected as the opening section 12, and the weakened groove 13 of the trim body 1 and the portion of the edge of one side of the trim body 1 close to the front of the vehicle in the horizontal direction can be selected as the fixed section 11; the side edge of the fixed section 11 away from the opening section 12 can be selected to be abutted and connected with the first side edge of the A-pillar sheet metal 2, and the side edge of the opening section 12 away from the fixed section 11 is connected to the second side edge of the A-pillar sheet metal 2.

[0068] A sealing strip 21 may be provided on the second side edge of the A-pillar sheet metal 2, and the sealing strip 21 may have a groove structure, which extends along the length direction of the A-pillar sheet metal 2, and the edge of the opening section 12 away from the fixed section 11 is plugged into the groove structure. Of course, a buckle may also be provided on the sealing strip 21, and the edge of the opening section 12 away from the fixed section 11 is connected to the buckle by buckle. Alternatively, it is not limited to providing a groove or buckle on the second side edge of the A-pillar sheet metal 2, so that the side edge of the opening section 12 away from the fixed section 11 is connected to the groove or buckle on the A-pillar sheet metal 2.

[0069] A raised structure may be optionally provided at the edge of the side of the fixed section 11 away from the opening section 12, and the raised structure is spaced apart from the edge of the side of the fixed section 11 away from the opening section 12. The first side edge of the A-pillar sheet metal 2 may be bent to form a folded edge, and the raised structure abuts against the folded edge. The edge of the trim body 1 close to the front of the vehicle abuts against the side of the folded edge in the horizontal direction, so that the edge of the trim body 1 abuts against the A-pillar sheet metal 2. Of course, it is also possible to provide an abutting groove on the edge of the first side panel of the A-pillar sheet metal 2, and insert the edge of the fixed section 11 away from the opening section 12 into the abutting groove, so that the fixed section 11 abuts against the A-pillar sheet metal 2.

[0070] The abutment between the first side edge of the A-pillar sheet metal 2 and the fixed section 11 forms a limiting structure for the side edge of the fixed section 11 away from the opening section 12, so that when the trim body 1 moves away from the A-pillar sheet metal 2, the fixed section 11 can rotate around the first side edge of the A-pillar sheet metal 2 in the direction away from the A-pillar sheet metal 2.

[0071] When the above-mentioned side air curtain 22 expands, it contacts the opening section 12 and applies a force to the opening section 12. When the force causes the opening section 12 to rotate around the weakened groove 13 relative to the fixed section 11, part of the force will also be transmitted to the fixed section 11 through the trim body 1 at the weakened groove 13, causing the fixed section 11 to rotate around the first side edge of the A-pillar sheet metal 2 in a direction away from the A-pillar sheet metal 2.

[0072] Reference Figure 1 , Figure 2 and Figure 3 As shown, in some embodiments, the weakened groove 13 has two groove walls arranged opposite to each other, and the two groove walls are inclined toward the direction of approaching each other in the direction from the groove opening to the groove bottom of the weakened groove 13. Such an arrangement enables the inner walls on both sides of the weakened groove 13 to be inclined relative to each other, thereby increasing the volume of the weakened groove 13, and ensuring that the areas on both sides of the weakened groove 13 can be relatively rotated at a larger angle when the trim body 1 is subjected to the impact force of the expansion of the side air curtain 22, so that a larger opening can be formed between the trim body 1 and the second side edge of the A-pillar sheet metal 2.

[0073] Specifically, the weakened groove 13 can be selected to extend along the length direction of the A-pillar sheet metal 2, and the weakened groove 13 has two opposite side groove walls along the width direction of the A-pillar sheet metal 2. The distance between the two opposite side groove walls of the weakened groove 13 gradually decreases along the groove opening of the weakened groove 13 toward the groove bottom of the weakened groove 13, so that the two opposite side groove walls of the weakened groove 13 are arranged to be inclined with respect to each other.

[0074] The angle between the inner walls on both sides of the weakening groove 13 can be selected to be between 60° and 120°; when the angle is less than 60°, the inclination between the inner walls on both sides of the weakening groove 13 is small, and the space inside the weakening groove 13 is small, which has limited effect on reducing the structural strength of the trim body 1 at the weakening groove 13, affecting the rotation angle of the opening section 12 relative to the fixed section 11; when the angle is set to be greater than 120°, the space inside the weakening groove 13 is larger, and the structural strength of the trim body 1 at the weakening groove 13 is too low, making it easy for the trim body 1 to break at the weakening groove 13 when deformed, resulting in the trim body 1 breaking when the side air curtain 22 expands, which can easily injure the occupants.

[0075] Reference Figures 1 to 6As shown, in some embodiments, the weakened groove 13 is disposed on the side of the trim body 1 facing the A-pillar sheet metal 2. In this way, the surface of the trim body 1 facing the vehicle occupant and facing away from the A-pillar sheet metal 2 is smooth without a groove structure, thereby improving the appearance of the trim body 1 after being installed on the A-pillar sheet metal 2.

[0076] Specifically, a weakened groove 13 is formed on one side of the trim body 1 facing the A-pillar sheet metal 2, so that the surface of the side of the trim body 1 facing away from the A-pillar sheet metal 2 is smooth, so as to enhance the appearance of the trim body 1 after being installed on the A-pillar sheet metal 2.

[0077] Reference Figure 1 , Figure 2 and Figure 3 As shown, in some embodiments, there is a second spacing between the bottom of the weakened groove 13 and the side of the trim body 1 facing away from the weakened groove 13, and the second spacing is between 1.5 mm and 2 mm. This arrangement ensures that the structural strength at the weakened groove 13 is suitable for deformation, so that when the side air curtain 22 expands, the areas on both sides of the weakened groove 13 can rotate relatively at a large angle without separation, ensuring that the trim body 1 will not break and fly out fragments after being subjected to the force of the side air curtain 22; at the same time, it ensures that the size of the opening formed between the trim body 1 and the A-pillar sheet metal 2 is large enough for the side air curtain 22 to pass smoothly.

[0078] Specifically, the distance between one side of the trim body 1 close to the A-pillar sheet metal 2 and one side of the trim body 1 facing away from the A-pillar sheet metal 2 is the thickness of the trim body 1. The thickness of the trim body 1 can be selected to be 2.5 mm to 3.5 mm. When the thickness of the trim body 1 is less than 2.5 mm, the overall structural strength of the trim body 1 is low, and the trim body 1 is easily broken under impact when the side air curtain 22 expands. When the thickness of the trim body 1 is greater than 3.5 mm, the overall structural strength of the trim body 1 is greater and is not easy to deform. When the side air curtain 22 expands, the deformation degree of the trim body 1 is small, which easily leads to an opening size that is difficult for the side air curtain 22 to pass through.

[0079] The above-mentioned second spacing can be selected to be 1.5 mm to 2 mm. When the second spacing is less than 1.5 mm, the structural strength of the weakened groove 13 of the trim body 1 is low. When the side air curtain 22 expands, the deformation degree of the weakened groove 13 of the trim body 1 is too large and it is easy to break. When the second spacing is greater than 1.5 mm, the weakened groove 13 has a poor effect on reducing the structural strength of the trim body 1. When the side air curtain 22 expands, the deformation degree of the weakened groove 13 of the trim body 1 is low, so that the relative rotation angle of the two side areas of the weakened groove 13 is smaller, which affects the opening size formed between the trim body 1 and the A-pillar sheet metal 2.

[0080] Reference Figures 7 to 15As shown, in some embodiments, a first clip 31 and a second clip 32 are provided on a side of the trim body 1 facing the A-pillar sheet metal 2, and a first mounting hole 23 and a second mounting hole 24 are provided on the A-pillar sheet metal 2. The first clip 31 is snap-connected to the first mounting hole 23, and the second clip 32 is snap-connected to the second mounting hole 24; the first mounting hole 23 and the second mounting hole 24 extend along the length direction of the A-pillar sheet metal 2, and the portion of the first clip 31 located in the first mounting hole 23 has a smaller size in the length direction of the A-pillar sheet metal 2 than the length size of the first mounting hole 23, and the portion of the second clip 32 located in the second mounting hole 24 has a smaller size in the length direction of the A-pillar sheet metal 2 than the length size of the second mounting hole 24.

[0081] Specifically, it is possible to select that two first buckles 31 and one second buckle 32 are provided on the trim body 1, the two first buckles 31 are spaced apart along the length direction of the A-pillar sheet metal 2, and one second buckle 32 is provided at a position on the side of the two first buckles 31 away from the front of the vehicle, and the A-pillar sheet metal 2 is provided with two first mounting holes 23 and one second mounting hole 24, the two second mounting holes 24 are provided corresponding to the two first buckles 31 and are mutually engaged. Of course, it is also possible to select that one first buckle 31 and one second buckle 32 are provided on the trim body 1, the first buckle 31 and the second buckle 32 are spaced apart along the length direction of the A-pillar sheet metal 2, and the first mounting hole 23 and the second mounting hole 24 on the A-pillar sheet metal 2 are provided corresponding to the first buckle 31 and the second buckle 32, respectively.

[0082] The above-mentioned first clip 31 can be selected as a clip structure formed by bending an elastic sheet, and the maximum size of the first clip 31 can be selected to be larger than the size of the first mounting hole 23, so that the first clip 31 can pass through the first mounting hole 23 by deformation to achieve the snap-on connection between the first clip 31 and the first mounting hole 23. Of course, the first clip 31 can also be selected to be a protruding structure, the protruding structure extends in a direction away from the trim body 1, and the end of the protruding structure away from the trim body 1 has an elastic head, and the elastic head extends in a direction perpendicular to the extension direction of the protruding structure. The protruding structure is adapted to the size and properties of the first mounting hole 23. When the protruding structure is inserted into the first mounting hole 23, the elastic head is deformed and passes through the first mounting hole 23, so that the first clip 31 and the first mounting hole 23 are snap-connected.

[0083] The above-mentioned second clip 32 can be selected to be a clip structure formed by bending an elastic sheet, and the maximum dimension of the second clip 32 can be selected to be larger than the dimension of the second mounting hole 24, so that the second clip 32 can pass through the first mounting hole 23 by deformation to achieve the clip-on connection between the second clip 32 and the second mounting hole 24. Of course, the second clip 32 can also be selected to be an elastic protrusion structure, and the dimension of the end of the elastic protrusion structure away from the trim panel body 1 is larger than the dimension of the second mounting hole 24, and the elastic protrusion structure passes through the second mounting hole 24 by deformation to achieve the clip-on connection between the second clip 32 and the second mounting hole 24.

[0084] The above-mentioned first mounting hole 23 and second mounting hole 24 are rectangular through holes arranged on the A-pillar sheet metal 2. Of course, the first mounting hole 23 and the second mounting hole 24 can also be selected as oblong holes arranged on the A-pillar sheet metal 2. The length direction of the A-pillar sheet metal 2 is the length direction of the first clip 31, the second clip 32, the first mounting hole 23 and the second mounting hole 24. The width dimension of the part of the first clip 31 used to snap with the first mounting hole 23 can be selected to be larger than the width dimension of the first mounting hole 23, so that after the first clip 31 passes through the first mounting hole 23, the two sides of the first clip 31 along the width direction can be snapped with the two sides of the first mounting hole 23 along the width direction; the width dimension of the part of the second clip 32 used to snap with the second mounting hole 24 can be selected to be larger than the width dimension of the second mounting hole 24, so that after the second clip 32 passes through the second mounting hole 24, the two sides of the second clip 32 along the width direction can be snapped with the two sides of the second mounting hole 24 along the width direction.

[0085] The difference between the length dimension of the portion of the first clip 31 located in the first mounting hole 23 and the length dimension of the first mounting hole 23 can be selected to be greater than or equal to 2 mm; the length dimension of the first mounting hole 23 is greater than the length dimension of the portion of the first clip 31 used for snapping with the first mounting hole 23, so that the first clip 31 has a certain amount of free space when being snapped with the first mounting hole 23, so as to reduce the influence of the processing errors of the trim body 1 and the A-pillar sheet metal 2 on the assembly; when the difference between the length dimension of the portion of the first clip 31 located in the first mounting hole 23 and the length dimension of the first mounting hole 23 is less than 2 mm, the free space of the first clip 31 in the first mounting hole 23 is small, and it is difficult to achieve the effect of reducing the influence of the processing errors of the trim body 1 and the A-pillar sheet metal 2 on the assembly.

[0086] The difference between the length dimension of the portion of the second clip 32 located in the second mounting hole 24 and the length dimension of the second mounting hole 24 can be selected to be greater than or equal to 2 mm; the length dimension of the second mounting hole 24 is greater than the length dimension of the portion of the second clip 32 used for snapping with the second mounting hole 24, so that the second clip 32 has a certain amount of free space when snapping with the second mounting hole 24, so as to reduce the influence of the processing errors of the trim body 1 and the A-pillar sheet metal 2 on the assembly; when the difference between the length dimension of the portion of the second clip 32 located in the second mounting hole 24 and the length dimension of the second mounting hole 24 is less than 2 mm, the free space of the second clip 32 in the second mounting hole 24 is small, and it is difficult to achieve the effect of reducing the influence of the processing errors of the trim body 1 and the A-pillar sheet metal 2 on the assembly.

[0087] The above-mentioned first clip 31 and second clip 32 can be optionally arranged on the fixed section 11, so that when the side air curtain 22 expands and the trim body 1 is deformed, the clamping of the first clip 31 with the first mounting hole 23 and the clamping of the second clip 32 with the second mounting hole 24 will not affect the deformation and movement of the opening section 12.

[0088] By providing the first buckle 31 and the second buckle 32 on the trim panel body 1, and providing the first mounting hole 23 and the second mounting hole 24 on the A-pillar sheet metal 2, the trim panel body 1 is moved toward the A-pillar sheet metal 2 so that the first buckle 31 and the second buckle 32 are respectively connected with the first mounting hole 23 and the second mounting hole 24, and the trim panel body 1 can be installed on the A-pillar sheet metal 2. The structure is simple, the connection between the trim panel body 1 and the A-pillar sheet metal 2 is stable, and the convenience of installing the trim panel body 1 on the A-pillar sheet metal 2 is improved; and the first The length dimension of the portion of the clip 31 located in the first mounting hole 23 is smaller than the length dimension of the first mounting hole 23, and the length dimension of the portion of the second clip 32 located in the second mounting hole 24 is smaller than the length dimension of the second mounting hole 24, so that the first clip 31 has a certain amount of free space in the first mounting hole 23, and the second clip 32 has a certain amount of free space in the second mounting hole 24, which can reduce the impact of processing errors of the trim panel body 1 and the A-pillar sheet metal 2 on assembly, and avoid the inability to install the trim panel body 1 on the A-pillar sheet metal 2 due to processing errors.

[0089] Reference Figure 7 , Figure 8 ,and Fig.10 Of Fig.13As shown, in some embodiments, a positioning pin 314 is further provided on the side of the trim body 1 facing the A-pillar sheet metal 2, and a positioning hole 231 is provided on the A-pillar sheet metal 2. When the first buckle 31 is connected to the first mounting hole 23, the positioning pin 314 is connected to the positioning hole 231. In this way, when the positioning pin 314 is inserted into the positioning hole 231, it can play a positioning role in the relative position of the trim body 1 and the A-pillar sheet metal 2, so that the first buckle 31 corresponds to the first mounting hole 23, and the second buckle 32 corresponds to the second mounting hole 24, thereby improving the convenience of installing the trim body 1 on the A-pillar sheet metal 2.

[0090] Specifically, the positioning pin 314 can be selected to be set at a peripheral position of the first buckle 31, and the positioning hole 231 can be set at a peripheral position of the first mounting hole 23. When the first buckle 31 and the first mounting hole 23 are set correspondingly, the positioning hole 231 and the positioning pin 314 are set correspondingly; when there are multiple first buckles 31 and multiple first mounting holes 23, the multiple first buckles 31 correspond one-to-one with the multiple first mounting holes 23, and at least one positioning pin 314 is provided around the periphery of each first buckle 31, and at least one positioning hole 231 is provided around each first mounting hole 23, and the multiple positioning holes 231 correspond one-to-one with the multiple positioning pins 314.

[0091] The above-mentioned positioning pin 314 can be selected as a raised structure extending in the direction away from the trim body 1. The raised structure can be selected as a frustum or a cone, that is, the end of the raised structure is in the direction toward the trim body 1, and the cross-sectional area of ​​the raised structure gradually increases, so that the end of the raised structure away from the trim body 1 can be easily inserted into the positioning hole 231. In the process of the trim body 1 moving toward the A-pillar sheet metal 2, the raised structure can play a guiding role.

[0092] Reference Figure 8 , Fig.10 , Fig.11 , Fig.12 and Fig.13 As shown, in some embodiments, the first buckle 31 includes a first mounting seat 311 and a first elastic buckle 312. The first mounting seat 311 is arranged on the decorative plate body 1. The first mounting seat 311 is provided with a first mounting groove 313. The first elastic buckle 312 is plugged into the first mounting groove 313. A portion of the first elastic buckle 312 is exposed on the surface of the first mounting seat 311 to be snap-connected with the first mounting hole 23. In this way, the first mounting seat 311 can be made integrally with the decorative plate body 1. Only the first elastic buckle 312 needs to be made of elastic material, so that the first elastic buckle 312 is arranged on the first mounting seat 311 by assembly, thereby reducing the cost of arranging the first buckle 31 on the decorative plate body 1.

[0093] The first mounting seat 311 is a protruding structure on the trim body 1 facing the A-pillar sheet metal 2, and a first mounting groove 313 is provided on a surface of the protruding structure close to the A-pillar sheet metal 2. The first elastic buckle 312 is formed by bending an elastic sheet. The first elastic buckle 312 includes a clamping portion and an inserting portion. The inserting portion is provided at one end of the clamping portion. The inserting portion is inserted into the first mounting groove 313 so that the inserting portion abuts against an inner wall of the first mounting groove 313, or the notch of the first mounting groove 313 is smaller than the bottom of the first mounting groove 313 so that the inserting portion can be clamped with the notch of the first mounting groove 313; the clamping portion extends out of the notch of the first mounting groove 313 from the notch of the first mounting groove 313, so that the clamping portion is exposed on the first mounting seat 311, so that the clamping portion can be used to insert into the first mounting hole 23 to realize the clamping connection between the first buckle 31 and the first mounting hole 23.

[0094] Of course, it is also possible to choose the first mounting seat 311 to be hollow inside, and set a through hole on the surface of the first mounting seat 311 facing the A-pillar sheet metal 2, the through hole is connected to the inside of the first mounting seat 311, and the through hole and the internal space of the first mounting seat 311 together form a first mounting groove 313, a part of the first elastic clip 312 enters the inside of the first mounting seat 311 through the through hole and is connected or abutted with the inner wall of the first mounting seat 311, so that the first elastic clip 312 is installed on the first mounting seat 311, and the other part is located on the outside of the first mounting seat 311 and is used to be connected with the first mounting hole 23.

[0095] The portion where the first elastic clip 312 is clipped with the first mounting seat 311 can be selected to have a length dimension that is smaller than the length dimension of the first mounting hole 23 and a width dimension that is larger than the width dimension of the first mounting hole 23, so that the first elastic clip 312 can be inserted into the first mounting hole 23 through elastic deformation, and the first elastic clip 312 is clipped with the first mounting hole 23 in the width direction.

[0096] When the side air curtain 22 expands and deforms the trim body 1, the first elastic clip 312 can be disengaged from the first mounting hole 23. Of course, it is also possible to keep the first elastic clip 312 connected to the first mounting hole 23 when the side air curtain 22 expands and deforms the trim body 1, so as to avoid excessive deformation of the trim body 1 and cause the trim body 1 to collide with the occupants in the vehicle.

The first elastic clip 312 is plugged into the first mounting groove 313. Part of the first elastic clip 312 is exposed on the surface of the first mounting seat 311 to be snap-connected with the first mounting hole 23.

[0098] The second mounting seat 321 may be selected as a raised structure on the trim body 1 facing the A-pillar sheet metal 2, and a second mounting groove 324 may be provided on a surface of the raised structure close to the A-pillar sheet metal 2. The second elastic buckle 322 may be selected as formed by bending an elastic sheet. The second elastic buckle 322 includes a clamping portion and an inserting portion. The inserting portion is provided at one end of the clamping portion. The inserting portion is inserted into the second mounting groove 324 so that the inserting portion abuts against an inner wall of the second mounting groove 324, or the notch of the second mounting groove 324 is smaller than the bottom of the second mounting groove 324, so that the inserting portion is clamped with the notch of the second mounting groove 324 in the second mounting groove 324, and the clamping portion extends out of the notch of the second mounting groove 324 from the notch of the second mounting groove 324, so that the clamping portion is exposed on the second mounting seat 321, so that the clamping portion can be used to be inserted into the second mounting hole 24 to realize the clamping connection between the second buckle 32 and the second mounting seat 321.

[0099] Of course, the interior of the second mounting seat 321 can also be hollow, and a through hole can be set on the surface of the second mounting seat 321 facing the A-pillar sheet metal 2, the through hole is connected to the interior of the second mounting seat 321, and the through hole and the internal space of the second mounting seat 321 together form a second mounting groove 324, a part of the second elastic clip 322 enters the interior of the second mounting seat 321 through the through hole and is connected or abutted with the inner wall of the second mounting seat 321, so that the second elastic clip 322 is installed on the second mounting seat 321, and the other part is located on the outside of the second mounting seat 321 and is used to be connected with the second mounting hole 24.

[0100] Reference Fig. 9 , Fig.14 and Fig.15 As shown, in some embodiments, an extension belt 323 is provided at the bottom of the second elastic buckle 322, and the extension belt 323 is located inside the second mounting seat 321, and one end of the extension belt 323 away from the second elastic buckle 322 is connected to the second mounting seat 321. In this way, when the side air curtain 22 expands and deforms the trim body 1, when the second elastic buckle 322 is separated from the second mounting groove 324, the extension belt 323 can still maintain the connection between the trim body 1 and the A-pillar sheet metal 2, so as to prevent the trim body 1 from moving too far and colliding with the occupants in the car, thereby improving the safety of the A-pillar trim when in use.

[0101] Specifically, the end of the second elastic buckle 322 close to the decorative panel body 1 is the bottom of the second elastic buckle 322, and the extension band 323 can be selected to be located in the second mounting groove 324. Of course, the second mounting seat 321 can also be selected to be hollow inside, and the extension band 323 is located inside the second mounting seat 321. The second mounting seat 321 can be selected to be provided with a buckle inside so that the extension band 323 is connected to the buckle inside the second mounting seat 321. Of course, the extension band 323 can also be selected to be provided with a limit member at the end away from the second elastic buckle 322, and a through hole is provided on the side of the second mounting seat 321. The extension band 323 extends out from the inside of the second mounting seat 321 through the hole, and the limit member is installed on the extension band 323 located outside the second mounting seat 321, and the size of the limit member is larger than the through hole, so that the limit member is engaged with the through hole.

[0102] When the side air curtain 22 is inflated and causes the trim body 1 to deform and move, the second elastic clip 322 can choose to maintain a snap connection with the second mounting hole 24, the second elastic clip 322 disengages from the second mounting groove 324, and the extension belt 323 gradually stretches and tightens, thereby preventing the trim body 1 from deforming and moving too far and causing the trim body 1 to collide and injure the occupants in the vehicle.

[0103] A second aspect of the disclosed embodiments provides a vehicle, comprising the A-pillar trim panel as described in any one of the above items.

[0104] By using the A-pillar trim as described above in the vehicle, when the vehicle collides, the side air curtain 22 is inflated to cause the trim body 1 to deform and move. The opening size formed between the trim body 1 and the A-pillar sheet metal 2 is sufficient for the side air curtain 22 to pass through, so that the side air curtain 22 can be smoothly popped out from the space between the trim body 1 and the A-pillar sheet metal 2, ensuring that the side air curtain 22 can protect the occupants in the vehicle.

[0105] When the A-pillar trim provided by the embodiment of the present disclosure is used, the trim body 1 is moved toward the A-pillar sheet metal 2, so that the first elastic clip 312 in the first clip 31 is snap-connected with the first mounting hole 23, the second elastic clip 322 in the second clip 32 is snap-connected with the second mounting hole 24, and the positioning pin 314 is inserted into the positioning hole 231, so that the trim body 1 can be installed on the A-pillar sheet metal 2, so that the trim body 1 shields the side air curtain 22 on the A-pillar sheet metal 2; when the vehicle collides, the side air curtain 22 is inflated and exerts an action on the opening section 12 of the trim body 1. Applying force, the weakened groove 13 on the trim body 1 is deformed, causing the opening section 12 to rotate relative to the fixed section 11 in the direction away from the A-pillar sheet metal 2, and the force on the opening section 12 is transmitted to the fixed section 11, the fixed section 11 is deformed and moved in the direction away from the A-pillar sheet metal 2, and an opening is formed between the edge of the opening section 12 away from the fixed section 11 and the second side edge of the A-pillar sheet metal 2, and the side air curtain 22 extends out of the space between the trim body 1 and the A-pillar sheet metal 2 through the opening, so that the side air curtain 22 forms a protective structure on the side of the interior of the vehicle to protect the occupants inside the vehicle.
