[0010] The utility model is provided with the cooperation of the support column, the first pushing block, the second pushing block, the stopping block, the clamping member, the butt plate, the through groove, the fastening block and the limiting plate. When the clamping member of the vehicle is matched, the second pushing block first contacts the fastening block, forms a thrust on the clamping member, causes it to expand to both sides, causes it to undergo elastic deformation, and the first pushing block then contacts the fastening block until the stopping block conflicts with the butt plate. Since the thickness of the first pushing block is greater than that of the second pushing block, a thrust is further formed on both sides of the clamping member to form an expansion. Since the top of the limiting plate is in contact with the two ends of the through groove, There is a spacing space left on the inner wall of the groove, and the limit plate is also squeezed by the first push block, forming an expansion and elastic deformation, and the expansion degree of the limit plate is different from that of the clamping piece, and then the reverse force of the limit plate clamps the first push block. At the same time, the fastening block further clamps and fixes the first push block due to the reverse force of the elastic deformation of the clamping piece, and the fastening block has a conical structure, which makes its clamping and fixation more firm. The double clamping and fixation makes the fit between the first push block and the clamping piece tighter and firmer, and it is not easy to shake due to the bumps and vibrations of driving, thus preventing the occurrence of abnormal noise.

[0018] The present invention will be further described below with reference to the accompanying drawings.

[0019] Reference Figure 1-5 As shown, the front sill trim of an automobile includes a sill shell 1, and a plurality of support columns 2 are evenly spaced at one end of the bottom of the sill shell 1. A first push block 3 is provided at the bottom end of the support column 2, and a second push block 4 is provided at the bottom end of the first push block 3. The bottom end of the second push block 4 is in an arc-shaped structure. The arc-shaped structure facilitates the second push block 4 to extend between the fastening blocks 503 and to push the fastening blocks 503 on both sides. The thickness of the second push block 4 is less than that of the first push block 3. The first push block 3 and the second push block 4 are stepped, and an arc chamfer is formed at the connection between the first push block 3 and the second push block 4. The first push block 3 and the second push block 4 contact the fastening block 503 in turn, push them, and gradually expand the distance between them, so that the first push block 3 can enter the interior of the clamping member 5.

[0020] A plurality of stop blocks 301 are arranged at intervals on the top of both ends of the first push block 3. A clamping member 5 with a U-shaped cross section is provided on the vehicle at a position corresponding to the first push block 3. The clamping member 5 is arranged at a corresponding position on the vehicle. When the door sill shell 1 is connected to the vehicle, the first push block 3 and the second push block 4 are located inside the clamping member 5. The open end of the clamping member 5 is symmetrically provided with abutment plates 501 in the horizontal direction that contact the stop blocks 301. The first push block 3 and the second push block 4 form a thrust on the clamping member 5, causing it to undergo elastic deformation. The reverse force of the clamping member 5 clamps and fixes the first push block 3, so that the first push block 3 is fixed inside the clamping member 5, and then a clamping connection is formed between the door sill shell 1 and the vehicle. After the first push block 3 and the clamping member 5 are in place, the bottom surface of the stop block 301 contacts the top surface of the butt plate 501.

[0021] The clamping member 5 is symmetrically provided with vertically arranged through grooves 502 on both sides, and two fastening blocks 503 arranged downwardly inclined are symmetrically provided at the top of the through grooves 502. The fastening blocks 503 are conical in structure. Due to the reverse force of the elastic deformation of the clamping member 5, the fastening blocks 503 clamp and fix the first push block 3. The conical structure of the fastening blocks 503 makes the clamping and fixation more firm, so as to prevent the occurrence of abnormal noise when the vehicle vibrates due to the assembly gap between the fastening blocks 503 and the first push block 3.

[0022] The bottom ends of the two through grooves 502 are symmetrically provided with curved limit plates 504. There is a gap between the inner walls of the two sides of the limit plates 504 and the inner walls of the two sides of the through grooves 502. The limit plates 504 are located between the two fastening blocks 503, and the top of the limit plates 504 is spaced from the top of the through grooves 502. Since there is a gap between the top and both ends of the limit plates 504 and the inner walls of the through grooves 502, the limit plates 504 are also squeezed by the first pushing block 3, forming an expansion and elastic The vehicle body 502 is fixed to the vehicle body 504 by the support member 506, and the support member 507 is fixed to the vehicle body 506 by the support member 508. The vehicle body 502 is fixed to the vehicle body 504 by the support member 508.

[0023] The first push block 3 extends horizontally to both ends to form a rib 302 on both sides, the top of the rib 302 is connected to the support column 2, and the inner side of the rib 302 conflicts with the two sides of the clamping member 5. The rib 302 limits the movement direction between the first push block 3, the second push block 3 and the clamping member 5 to prevent the first push block 3 and the second push block 4 from detaching from the clamping member 5 during the clamping process. A first reinforcing rib 303 connected to the support column 2 is provided on the outer side of the rib 302. The first reinforcing rib increases the structural strength of the rib 302, making it less likely to be deformed and damaged due to external force during installation and disassembly.

[0024] A first connecting arm 6 arranged in a vertically downward state is provided between adjacent support columns 3, a base 601 is provided at the bottom end of the first connecting arm 6, a horizontal plate 602 extending horizontally toward the outside of the threshold shell 1 is provided at one end of the first connecting arm 6, a card plate 603 in a vertically upward state is provided at the end of the horizontal plate 602 away from the first connecting arm 6, a guide slope is provided at the end of the card plate 603 close to the first connecting arm 6, a card groove 604 is formed between the card plate 603 and the first connecting arm 6, the card groove 604 cooperates with the guide slope to facilitate the flange at the corresponding position of the vehicle to enter between the card plate 603 and the first connecting arm 6, further forming a limit for the threshold shell 1 to prevent it from shaking horizontally.

[0025] A second reinforcing rib 605 is symmetrically arranged at the bottom end of the horizontal plate 602. The rear end face of the second reinforcing rib 605 is connected to the front end face of the first connecting arm 6. The second reinforcing rib 605 makes the structural strength of the connection between the horizontal plate 602 and the first connecting arm 6 higher, and is not easily deformed or damaged under external force during installation and disassembly.

[0026] Both sides of the middle of the threshold shell 1 are provided with a clamping assembly, which includes a second connecting arm 701 symmetrically arranged at the bottom end of the front threshold shell 1, a transverse connecting plate 702 arranged between the two second connecting arms 701 and connected to the two second connecting arms 701, and a clamping block 703 arranged at the bottom end of the second connecting arm 701 away from the transverse connecting plate 702. The second connecting arm 701 is arranged in a vertical downward state, the top end of the transverse connecting plate 702 is connected to the threshold shell 1, and the bottom end of the clamping block 703 away from the second connecting arm 701 is provided with A clamping space is formed between the driving inclined surface 704 and the two connecting arms 701, and when the clamping block 703 is clamped with the vehicle, the driving inclined surface 704 is squeezed first, causing the two clamping blocks 703 and the second connecting arm 701 to tilt and approach each other, and undergo elastic deformation until the squeezing force on the clamping block 703 disappears, and the second connecting arm 701 rebounds, causing the clamping block 703 to be clamped with the corresponding position, further increasing the stability and firmness of the connection between the threshold shell 1 and the vehicle. Their mutual cooperation makes it difficult for the threshold shell 1 to shake due to the bumpy vibration of driving, thereby preventing the occurrence of abnormal noise.
