Description

Technical Field

[0001] This utility model relates to the field of automotive interiors, specifically to a bolt mounting platform and an interior panel body on an automotive pillar. Background Technology

[0002] The interior trim panel is installed on the inside of the car pillar. The interior trim panel serves a decorative and aesthetic purpose. An air curtain is installed on the inside of the interior trim panel. In the event of an emergency such as a car collision, the air curtain will inflate rapidly and burst, causing damage to the interior trim panel at the weakening groove, creating a gap. The air curtain will then pop out from the gap at the weakening groove of the interior trim panel, thereby providing cushioning protection for the passengers.

[0003] The existing installation method for the pillar interior panel body and the pillar is as follows: The inner side of the pillar interior panel body has a bolt mounting recess. The bolts pass through the bolt mounting recess and connect to the pillar, thus fixing the pillar interior panel body and the pillar. Simultaneously, a cover is snapped onto the front part of the pillar interior panel body corresponding to the bolt mounting recess. The cover conceals the bolt mounting recess and the bolts on it, preventing the bolt mounting recess and bolts from being exposed, resulting in a more aesthetically pleasing installation of the interior panel body on the pillar.

[0004] However, in the existing technology, when the air curtain interior panel body is subjected to an explosion test, the root of the bolt-mounted platform will tear when the air curtain explodes, causing the root of the bolt-mounted platform to separate from the interior panel body. In this case, the bolt-mounted platform is still fixed to the column by bolts, but the bolt-mounted platform no longer restrains the interior panel body. After the interior panel body separates from the bolt-mounted platform, it will fly towards the human body, thereby causing injury to the human body upon impact, which poses a certain safety hazard. Utility Model Content

[0005] This utility model aims to provide a bolt-mounting countersunk platform and an interior panel body on a car pillar to solve the problem of tearing at the root of the bolt-mounting countersunk platform.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a bolt-mounted countersunk platform, comprising a countersunk platform body, one end of which is provided with a bolt hole, and the other end of which is provided with a root of the countersunk platform body. The projection of the countersunk platform body at the root is located within the root range. Multiple reinforcing ribs are provided on the outer side of the countersunk platform body. The multiple reinforcing ribs are distributed around the outer side of the countersunk platform body, and the ends of the reinforcing ribs extend at least to the root of the countersunk platform body.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: an interior panel body on a car pillar, wherein the inner side of the interior panel body on the car pillar is provided with a bolt mounting countersunk.

[0008] The principle and advantages of this patented solution are as follows: by setting multiple reinforcing ribs on the outer side of the sinking platform, the multiple reinforcing ribs surround the outer side of the sinking platform, thereby strengthening the structure of the sinking platform. When the air curtain explodes, the sinking platform is not easily damaged, and the sinking platform can still maintain its shape and be fixed to the column by bolts.

[0009] Meanwhile, since the ends of the reinforcing ribs extend at least to the root of the platform, the portion of the reinforcing ribs extending to the root of the platform plays a structural strengthening role at the root of the platform. The root of the platform is less prone to tearing or damage. Thus, during the air curtain explosion, the root of the platform is prevented from tearing and separating from the interior panel body on the car pillar, greatly improving safety.

[0010] At the same time, the reinforcing ribs are connected to both the base of the sloping platform and the base of the sloping platform, which can be firmly connected to the base of the sloping platform, greatly improving the connection strength between the base of the sloping platform and the base of the sloping platform. The base of the sloping platform is not prone to breakage or damage at the base, and the base of the sloping platform is not prone to breakage or separation, which greatly improves the safety of the interior panel body on the car pillar during the air curtain explosion.

[0011] In summary, the reinforcing ribs in this patent provide structural reinforcement for the pedestal body itself, the root of the pedestal body itself, and the connection between the pedestal bodies and their roots. During the air curtain explosion, the pedestal body is less likely to be damaged, the root of the pedestal body is less likely to be torn, and the pedestal body and its roots are less likely to break, greatly improving the safety of the interior panel body on the car pillar during the air curtain explosion.

[0012] Preferably, as an improvement, the number of reinforcing ribs is 6-10.

[0013] Preferably, as an improvement, the thickness of the reinforcing rib is 1-2 mm.

[0014] Preferably, as an improvement, the length of the sinking platform is 25-35mm.

[0015] Preferably, as an improvement, the base is provided with a locking hole, a positioning hole, and an anti-detachment hole, all located between two adjacent reinforcing ribs. The locking hole allows the locking block on the cover to pass through and lock onto the base. The positioning hole allows the positioning block on the cover to pass through, serving as the positioning function for the cover installation. The anti-detachment hole allows the anti-detachment component on the cover to pass through, and the anti-detachment component acts on the base to prevent the cover from detaching.

[0016] In this application, the locking holes, positioning holes, and anti-detachment holes are all located between two adjacent reinforcing ribs. The reinforcing ribs do not affect the setting of the locking holes, positioning holes, and anti-detachment holes, and at the same time, the locking holes, positioning holes, and anti-detachment holes do not affect the setting of the reinforcing ribs.

[0017] Preferably, as an improvement, the number of locking holes is at least two, with the two locking holes located on both sides of the recessed platform. This allows the two locking holes to engage with the two locking blocks, making the cover and the interior panel body on the car pillar more stable.

[0018] Preferably, as an improvement, the inner side of the interior trim panel body on the car pillar is provided with multiple connecting ribs, which extend to the root. Thus, the connector extends to the root, and the connecting ribs reinforce the root. Simultaneously, the connector improves the connection strength between the root and the interior trim panel body on the car pillar, making it less likely for the root to separate from the interior trim panel body during air curtain explosion. This ensures that the interior trim panel body remains restrained by the platform, preventing it from detaching from the platform and flying towards the body, further improving safety.

[0019] Preferably, as an improvement, the connecting ribs and reinforcing ribs are connected. Thus, by connecting the ribs and reinforcing ribs, the strength of the connection between the root and the interior panel body on the vehicle pillar is further improved. Attached Figure Description

[0029] Example 1

[0030] The basics are as follows: Figures 1-7 As shown: This embodiment discloses an interior trim panel body 1 for a car pillar. The inner side (back) of the interior trim panel body 1 is integrally provided with a bolt mounting countersunk. The outer side (front) of the interior trim panel body 1 for the car pillar is provided with a cover 2, combined with... Figure 7 As shown, the outer side of the interior panel body 1 on the car pillar is provided with a cover groove 14 corresponding to the bolt mounting countersunk, and the cover 2 is closed in the cover groove 14.

[0031] Combination Figure 4 and Figure 5 As shown, the bolt mounting countersunk platform in this embodiment includes a countersunk platform body 3. One end of the countersunk platform body 3 has a bolt hole 10, which is used for bolts to pass through and fix the bolt mounting countersunk platform to the pillar, thereby fixing the interior panel body 1 of the car pillar to the pillar. The other end of the countersunk platform body 3 has an integrally formed root 6, which is integrally formed on the interior panel body 1 of the car pillar. The root 6 of the countersunk platform body 3 is formed by sinking the cover groove 14. In this embodiment, the countersunk platform body 3 is cylindrical in shape, and the length of the countersunk platform body 3 is 25-35mm. In this embodiment, the thickness of the root 6 of the countersunk platform body 3 is 3-5mm, that is, the height of the root 6 protruding from the back of the interior panel body 1 of the car pillar is 3-5mm. Since the root 6 of the countersunk platform body 3 is formed by sinking the cover groove 14, the thickness of the root 6 is consistent with the depth of the cover groove 14.

[0032] The projection of the recessed platform 3 onto the root 6 is located within the area of ​​the root 6. Multiple reinforcing ribs 4, numbering 6-10, are provided on the outer surface of the recessed platform 3. The thickness of the reinforcing ribs 4 is 1-2 mm. These reinforcing ribs 4 are distributed around the outer surface of the recessed platform 3, with one end pointing towards the end of the recessed platform 3 where the bolt hole 10 is located, and the other end extending at least to the root 6 of the recessed platform 3, more specifically to the edge of the root 6. Thus, the multiple reinforcing ribs 4 on the outer surface of the recessed platform 3 strengthen the structure of the recessed platform 3, making it less prone to damage. Simultaneously, the extension of the reinforcing ribs 4 to the root 6 of the recessed platform 3 also strengthens the structure of the root 6, making it less prone to tearing or damage. Furthermore, the reinforcing ribs 4 connect the recessed platform 3 and the root 6 of the recessed platform 3 as a whole, making them less likely to break or separate.

[0033] Therefore, by setting the reinforcing rib 4, the strength of the base 3, the root 6, and the combination of the two are improved. During the air curtain explosion test, the base 3 and the root 6 are not easily damaged, thereby avoiding the safety accident caused by the root 6 (or the base 3) separating from the interior panel body 1 on the car pillar and the interior panel body 1 flying towards the human body.

[0034] In this embodiment, the reinforcing rib 4 is shaped like a right triangle, with the two right-angled sides of the right triangle located on the outer surface of the sinker body 3 and the root 6, respectively.

[0035] In addition, to improve the connection between the root 6 and the interior panel body 1 on the car pillar, in this embodiment, a plurality of connecting ribs 5 are integrally provided on the inner side of the interior panel body 1 on the car pillar. The connecting ribs 5 extend to the edge of the root 6. More specifically, the connecting ribs 5 and the reinforcing ribs 4 are integrally connected. Thus, by setting the connecting ribs 5 and extending them to the edge of the root 6, the connection between the root 6 and the interior panel body 1 on the car pillar is improved. During the air curtain burst test, the root 6 is less likely to separate from the interior panel body 1 on the car pillar, thus preventing the interior panel body 1 from flying towards the human body and causing a safety accident.

[0036] Combination Figure 4 and Figure 5 As shown, in this embodiment, the root portion 6 is provided with a locking hole 7, a positioning hole 9, and an anti-detachment hole 8. There are two locking holes 7, which are located on both sides of the recessed platform 3. The locking holes 7, positioning holes 9, and anti-detachment holes 8 are all located between two adjacent reinforcing ribs 4, so that the reinforcing ribs 4 and the locking holes 7 (or positioning holes 9 and anti-detachment holes 8) will not interfere with each other. In this embodiment, the back of the shielding cover 2 is integrally formed with two locking blocks 11, a positioning block 12, and an anti-detachment component 13. In this way, the shielding cover 2 covers the cover groove 14, the two locking blocks 11 are respectively locked in the two locking holes 7, the positioning block 12 passes through the positioning hole 9, and the anti-detachment component 13 is inserted into the anti-detachment hole 8.

[0037] Example 2

[0038] This embodiment is a further improvement on embodiment 1. In this embodiment, metal wires, such as steel wires or iron wires, are injection molded and embedded inside the interior panel body 1 of the car pillar. The metal wires extend into the root 6, that is, the metal wires are also injection molded and embedded in the root 6. In this way, when the air curtain explodes, the setting of the metal wires greatly improves the firmness and strength of the root 6. The root 6 is not easy to tear or separate from the interior panel body 1 of the car pillar, thereby avoiding safety accidents caused by the interior panel body 1 of the car pillar flying towards the human body.
