[0032] Please see Figures 1-6A multifunctional automotive trim piece includes a frame 1. A rear bumper 2 is detachably mounted on one side of the frame 1. A splicing device is also detachably mounted on one side of the frame 1. The splicing device includes a splicing sleeve 3, a splicing rod 4, a splicing block 5, a moving groove 6, and a releasing groove 7. The splicing sleeve 3 is detachably fitted onto the outside of the splicing rod 4. The splicing block 5 is fixedly mounted on the outside of the splicing rod 4. The moving groove 6 is located at the top inside the splicing sleeve 3. The releasing groove 7 is located on the inner side wall of the splicing sleeve 3. A reinforcing mechanism is installed on the outside of the splicing rod 4. The reinforcing mechanism includes a linkage spring 8, a limiting block 9, a locking sleeve 10, a releasing sleeve 11, a transverse groove 12, a longitudinal groove 13, and a variable... The system includes a diameter groove 14, a locking rod 15, a linkage block 40, a return spring 16, and a locking groove 17. The linkage spring 8 is connected to two adjacent linkage blocks 40. The limiting block 9 is fixedly installed on the outside of the splicing sleeve 3. The locking sleeve 10 is movably installed on the outside of the splicing sleeve 3 via a thread. The release sleeve 11 is rotatably installed on the outside of the splicing sleeve 3. The transverse groove 12 is opened on the outside of the splicing rod 4. The bottom end of the longitudinal groove 13 is connected to the transverse groove 12. The variable diameter groove 14 is opened on the inside of the release sleeve 11. One end of the locking rod 15 is connected to the outer wall of the splicing sleeve 3 via the return spring 16. The locking rod 15 is slidably installed on the side wall of the splicing sleeve 3. The locking groove 17 is opened at the other end of the transverse groove 12.

[0033] A mounting bracket 18 is fixedly provided on the inner side of the rear bumper 2, and fixing brackets 19 are symmetrically provided on both sides of the mounting bracket 18. Connecting brackets 20 are provided on both sides of the interior of the rear bumper 2.

[0034] In this embodiment, the mounting bracket 18 installed on one side of the rear bumper 2, along with two opposing fixing brackets 19 and two connecting brackets 20, forms a stable five-point connection with the vehicle frame 1, effectively ensuring the connection strength between the rear bumper 2 and the vehicle frame 1. As an important decorative component of modern automobiles, the rear bumper 2 not only has basic collision protection functions but also integrates various practical functions and aesthetic designs. In terms of safety, the rear bumper 2 effectively reduces collision impact, protecting the vehicle body and occupants, while also providing structural protection against scratches, deformation, and corrosion. In terms of practical functions, the modern rear bumper 2 integrates intelligent auxiliary devices such as reversing radar, camera mounting positions, distance sensors, and blind spot monitoring systems. Some high-end models are also equipped with foot-activated tailgate opening and night vision features. The rear bumper features practical designs such as a central lighting system, a detachable tow hook, and convenient running boards. In terms of aesthetics, the bumper enhances the vehicle's overall appeal through meticulously designed styling, electroplating, unique paintwork, light strips, and brand logos. It can also be customized through sports kits, aftermarket parts, trim strips, exhaust trim, and wraps. For special functions, the rear bumper incorporates aerodynamic design elements, such as airflow guidance, drag reduction, improved stability, heat dissipation, and noise reduction. It also utilizes recyclable materials and a lightweight design to reflect environmental protection principles. This integration of diverse functions significantly improves the user experience and product value, enhances market competitiveness, meets diverse consumer needs, and improves the overall performance and lifespan of the vehicle.

[0035] Please see Figures 3-6 As a further implementation of the overall equipment: a plurality of linkage rails 21 are fixedly provided on one side of the release sleeve 11, and a linkage groove 22 is provided on one side of the linkage block 40, the linkage groove 22 being adapted to the linkage rails 21.

[0036] Limiting block 9 is designed with a cylindrical structure.

[0037] One side of the linkage block 40 is equipped with a linkage wheel 23, which is engaged between two corresponding limit blocks 9.

[0038] The internal movement angles of the movable slot 6 and the transverse slot 12 are the same.

[0039] The longitudinal groove 13 and the locking groove 17 have the same depth, and the depth of the longitudinal groove 13 and the locking groove 17 is greater than the depth of the transverse groove 12.

[0040] Both the bottom side of the longitudinal groove 13 and the side of the locking groove 17 adopt a rounded corner structure design.

[0041] More specifically, when the rear bumper 2 needs to be disassembled, first rotate the locking sleeve 10 forward, causing it to move along the threads on the outside of the splicing sleeve 3, so that the locking sleeve 10 no longer limits the outer side of the linkage wheel 23. Then rotate the release sleeve 11 forward, causing it to drive the linkage block 40 to rotate through the linkage rail 21 and linkage groove 22. The linkage block 40 will then drive the linkage wheel 23 installed on one side to roll out between the two limiting blocks 9. At the same time, the linkage block 40 will slide outward along the linkage rail 21 and linkage groove 22, and the linkage block 40 will drive the linkage spring 8 to stretch outward. Simultaneously, the release sleeve 11 will drive the inner variable diameter groove 14 to rotate. When the release sleeve 11 can no longer rotate, the wider side of the variable diameter groove 14 aligns with the locking rod 15. Then, rotate the splicing rod 4 clockwise, causing the locking groove 17, longitudinal groove 13, and transverse groove 12 to rotate. The inner wall of the locking groove 17 then presses against the end of the locking rod 15, causing one end of the locking rod 15 to slide out of the locking groove 17 and into the transverse groove 12. Simultaneously, the other end of the locking rod 15 stretches the return spring 16. At the same time, the splicing rod 4 causes the splicing block 5 to slide along the moving groove 6. When the locking rod 15 moves to the position corresponding to the longitudinal groove 13, the return spring 16 causes the locking rod 15 to slide in the opposite direction, inserting the other end of the locking rod 15 into the longitudinal groove 13. Simultaneously, the splicing block 5 rotates to the position corresponding to the release groove 7. Then, pull the splicing sleeve 3 and the splicing rod 4 to their respective ends, causing the splicing rod 4 to slide the splicing block 5 out along the release groove 7, thus removing the splicing sleeve 3. Remove the splicing rod 4, and then remove the other splicing sleeves 3 and splicing rod 4 according to the above steps. Then remove the rear bumper 2 from the rear side of the frame 1. When it is necessary to install the rear bumper 2, first align the reserved holes on the mounting bracket 18, connecting bracket 20 and fixing bracket 19 with the reserved holes on the rear side of the frame 1. The cross-sectional shape of the reserved holes is the same as the cross-sectional shape of the splicing rod 4 with the splicing block 5. Then pass the splicing rod 4 through from one side, and then fit the splicing sleeve 3 onto the outside of the splicing rod 4 from the other side, so that the splicing block 5 slides into the release groove 7 and the locking rod 15 slides into the longitudinal groove 13. When the splicing block 5 moves to the top of the release groove 7, the locking rod 15 moves to the bottom of the longitudinal groove 13. Then rotate the splicing rod 4 in the opposite direction, so that... The splicing rod 4 drives the longitudinal groove 13, the transverse groove 12, and the locking groove 17 to rotate in opposite directions. Then, the bottom sidewall of the longitudinal groove 13 presses against one end of the locking rod 15, causing one end of the locking rod 15 to slide out from the bottom of the longitudinal groove 13 and into the transverse groove 12. At the same time, the other end of the locking rod 15 drives the return spring 16 to stretch. Simultaneously, the splicing block 5 rotates in opposite directions along the moving groove 6. When the splicing block 5 moves to the other end of the moving groove 6, the locking rod 15 moves to the position corresponding to the locking groove 17. Then, the return spring 16 drives the locking rod 15 to slide back and insert into the locking groove 17. Then, the release sleeve 11 rotates in opposite directions, causing the release sleeve 11 to drive the linkage block 40 and the linkage wheel 23 to move in opposite directions through the linkage rail 21 and the linkage groove 22. The release sleeve 11 also drives the internal variable diameter groove 14 to rotate in opposite directions.The narrower side of the variable diameter groove 14 aligns with the locking rod 15, limiting the outer end of the locking rod 15 and preventing it from sliding. This locks the splicing rod 4 and the splicing sleeve 3. At this point, the linkage block 40 and the linkage wheel 23 move to positions corresponding to the original two limiting blocks 9. Then, the linkage spring 8 pulls the linkage block 40, causing the linkage wheel 23 to slide inwards along the linkage rail 21 and linkage groove 22, repositioning it between the original two limiting blocks 9. Then, the locking sleeve 10 rotates in the opposite direction, repositioning it to limit the outer side of the linkage wheel 23, ensuring it is stably engaged between the two limiting blocks 9. This limits the release sleeve 11, ensuring stable installation.

[0042] In summary, during use or operation, the mounting bracket 18 installed on one side of the rear bumper 2, along with the two opposing fixing brackets 19 and two connecting brackets 20, forms a stable five-point connection with the vehicle frame 1, effectively ensuring the connection strength between the rear bumper 2 and the vehicle frame 1. As an important decorative component of modern automobiles, the rear bumper 2 not only has basic collision protection functions but also integrates various practical functions and aesthetic design. In terms of safety, the rear bumper 2 effectively reduces collision impact, protecting the vehicle body and occupants, while also providing structural protection against scratches, deformation, and corrosion. In terms of practical functions, the modern rear bumper 2 integrates intelligent auxiliary devices such as reversing radar, camera mounting positions, distance sensors, and blind spot monitoring systems. Some high-end models are also equipped with foot-activated opening. Practical features include a tailgate, night lighting system, detachable tow hook, and convenient running boards. In terms of aesthetics, the bumper enhances the vehicle's overall appeal through meticulously designed styling, electroplating, unique paintwork, light strips, and brand logos. Personalization is also possible through sports kits, aftermarket parts, trim strips, exhaust tip decorations, and wraps. For special functions, the rear bumper incorporates aerodynamic design elements such as airflow guidance, drag reduction, improved stability, heat dissipation, and noise reduction. The use of recyclable materials and lightweight design reflects an environmentally conscious philosophy. This integration of diverse functions significantly enhances the user experience and product value, strengthens market competitiveness, meets diverse consumer needs, and improves the overall performance and lifespan of the vehicle.

[0043] When the rear bumper 2 needs to be disassembled, first rotate the locking sleeve 10 forward, causing it to move along the threads on the outside of the splicing sleeve 3, so that the locking sleeve 10 no longer limits the outer side of the linkage wheel 23. Then rotate the release sleeve 11 forward, causing it to drive the linkage block 40 to rotate through the linkage rail 21 and linkage groove 22. The linkage block 40 will then drive the linkage wheel 23 installed on one side to roll out between the two limiting blocks 9. At the same time, the linkage block 40 will slide outward along the linkage rail 21 and linkage groove 22, and the linkage block 40 will drive the linkage spring 8 to stretch outward. Simultaneously, the release sleeve 11 will drive the inner variable diameter groove 14 to rotate. When the release sleeve 11 can no longer rotate, the wider side of the variable diameter groove 14 aligns with the locking rod 15. Then rotate forward... Rotate the splicing rod 4, causing the locking groove 17, longitudinal groove 13, and transverse groove 12 to rotate. The inner wall of the locking groove 17 then presses against the end of the locking rod 15, causing one end of the locking rod 15 to slide out of the locking groove 17 and into the transverse groove 12. Simultaneously, the other end of the locking rod 15 stretches the return spring 16. At the same time, the splicing rod 4 causes the splicing block 5 to slide along the moving groove 6. When the locking rod 15 moves to the position corresponding to the longitudinal groove 13, the return spring 16 causes the locking rod 15 to slide in the opposite direction, inserting the other end of the locking rod 15 into the longitudinal groove 13. Simultaneously, the splicing block 5 rotates to the position corresponding to the release groove 7. Then, pull the splicing sleeve 3 and the splicing rod 4 to their respective ends, causing the splicing rod 4 to slide the splicing block 5 out along the release groove 7. This allows the splicing sleeve 3 and the splicing block 5 to be removed. Remove rod 4, and then remove the other splicing sleeves 3 and splicing rod 4 according to the above steps. Then remove the rear bumper 2 from the rear side of the frame 1. When the rear bumper 2 needs to be installed, first align the reserved holes on the mounting bracket 18, connecting bracket 20 and fixing bracket 19 with the reserved holes on the rear side of the frame 1. The cross-sectional shape of the reserved holes is the same as the cross-sectional shape of the splicing rod 4 with the splicing block 5. Then pass the splicing rod 4 through from one side, and then fit the splicing sleeve 3 onto the outside of the splicing rod 4 from the other side, so that the splicing block 5 slides into the release groove 7 and the locking rod 15 slides into the longitudinal groove 13. When the splicing block 5 moves to the top of the release groove 7, the locking rod 15 moves to the bottom of the longitudinal groove 13. Then rotate the splicing rod 4 in the opposite direction, so that the splicing block 5 slides into the release groove 7 and the locking rod 15 slides into the longitudinal groove 13. When the splicing block 5 moves to the top of the release groove 7, the locking rod 15 moves to the bottom of the longitudinal groove 13. Then rotate the splicing rod 4 in the opposite direction, so that the splicing block 5 slides into the release groove 7 and the locking rod 15 slides into the longitudinal groove 13. The connecting rod 4 drives the longitudinal groove 13, the transverse groove 12, and the locking groove 17 to rotate in opposite directions. Then, the bottom side wall of the longitudinal groove 13 presses against one end of the locking rod 15, causing one end of the locking rod 15 to slide out from the bottom of the longitudinal groove 13 and into the transverse groove 12. At the same time, the other end of the locking rod 15 drives the return spring 16 to stretch. Simultaneously, the splicing block 5 rotates in opposite directions along the moving groove 6. When the splicing block 5 moves to the other end of the moving groove 6, the locking rod 15 moves to the position corresponding to the locking groove 17. Then, the return spring 16 drives the locking rod 15 to slide back and insert into the locking groove 17. Then, the release sleeve 11 rotates in opposite directions, causing the release sleeve 11 to drive the linkage block 40 and the linkage wheel 23 to move in opposite directions through the linkage rail 21 and the linkage groove 22. The release sleeve 11 also drives the internal variable diameter groove 14 to rotate in opposite directions.The narrower side of the variable diameter groove 14 aligns with the locking rod 15, limiting the outer end of the locking rod 15 and preventing it from sliding. This locks the splicing rod 4 and the splicing sleeve 3. At this point, the linkage block 40 and the linkage wheel 23 move to positions corresponding to the original two limiting blocks 9. Then, the linkage spring 8 pulls the linkage block 40, causing the linkage wheel 23 to slide inwards along the linkage rail 21 and linkage groove 22, repositioning it between the original two limiting blocks 9. Then, the locking sleeve 10 rotates in the opposite direction, repositioning it to limit the outer side of the linkage wheel 23, ensuring it is stably engaged between the two limiting blocks 9. This limits the release sleeve 11, ensuring stable installation.

For all the fixed connections mentioned above, welding is preferred. Although embodiments of this utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this utility model.
