[0035] The metal buckle assembly provided in this application includes: the lower tailgate trim panel 1, the vehicle body sheet metal 2, and the buckle body 3.

[0036] Among them, as Figure 6 shown, an installation hole 10 is provided at the upper edge of the lower tailgate trim panel 1. As Figure 7 and Figure 8 shown, the buckle body 3 includes a bottom plate 30, a trim panel connecting part 4 and a sheet metal connecting part 5 arranged on the bottom plate 30. The trim panel connecting part 4 includes a pressing plate 50 arranged opposite to the bottom plate 30 and anti-disengagement pieces 51 located on both sides of the pressing plate 50. The sheet metal connecting part 5 includes a clamping main body 40 and an anti-disengagement elastic piece 400 located on the clamping main body 40.

[0037] As Figure 3 shown, the vehicle body sheet metal 2 is embedded between the bottom plate 30 and the pressing plate 50. As Figures 7 to 8 shown, the end of the anti-disengagement piece 51 abuts against the vehicle body sheet metal 2 embedded between the bottom plate 30 and the pressing plate 50. As Figure 3 shown, a part of the structure of the clamping main body 40 is embedded in the installation hole 10, and the protrusion 401 of the anti-disengagement elastic piece 400 and the pressing plate 50 abut against the two side edges of the installation hole 10 to position the lower tailgate trim panel 1 where the installation hole 10 is located.

[0038] Please refer to Figures 7 to 8 Optionally, the protrusion 401 is located at the end of the anti-drop spring sheet 400, the protrusion 401 extends in a direction away from the clamping body 40 and the end is bent in a direction close to the clamping body 40 to form a bending area, such as Figure 3 As shown, the bending area of ​​the protrusion 401 abuts against the outer side of the mounting hole 10, in order to further increase the mounting stability between the protrusion 401 and the mounting hole 10, as shown in FIG. Figure 3 As shown, the end portion of the protrusion 401 extends into the interior of the mounting hole 10 .

[0039] The body sheet metal 2 can be located on the tailgate sheet metal, specifically, at a position close to the upper edge of the tailgate lower trim panel 1, such as Figures 1 to 2 As shown, the two can be connected through the buckle body 3.

[0040] The width of the mounting hole 10 is smaller than the maximum lateral distance of the raised portion 401 in the free state. In the process of pressing the mounting hole 10 down from the end of the clamping body 40, when contacting the raised portion 401 of the anti-slip spring sheet 400, the raised portion 401 is subjected to force and retracts to reduce the lateral distance under the drive of the anti-slip spring sheet 400, so as to facilitate the mounting hole 10 to pass over the raised portion 401 and be pressed down. After the mounting hole 10 passes over the raised portion 401, the raised portion 401 returns to a state where the lateral distance is greater than the mounting hole 10 under the drive of the anti-slip spring sheet 400 and abuts against the two side edges of the mounting hole 10 with the pressure plate 50 respectively, thereby fixing the upper edge of the lower tailgate trim panel 1 where the mounting hole 10 is located.

[0041] The metal buckle assembly provided in the present application is embedded and fixed between the bottom plate 30 and the pressure plate 50 of the buckle body 3 through the body sheet metal 2, and is doubly fastened by the anti-slip sheet 51; the two sides of the mounting hole 10 on the tailgate lower trim panel 1 are limited by the protrusions 401 of the anti-slip spring sheet 400 on the clamping body 40 and the pressure plate 50, thereby stably connecting the tailgate lower trim panel 1 to the body sheet metal 2, effectively fixing the upper edge of the tailgate lower trim panel 1, and preventing the tailgate lower trim panel 1 from colliding with the tailgate sheet metal or tailgate glass due to vibration during the driving of the vehicle to produce abnormal noise, and occupying little space.

[0042] In an alternative embodiment, the buckle body 3 includes a first buckle plate 31, a second buckle plate 32, and a third buckle plate 33 that are foldably connected to a connecting edge 300 of the bottom plate 30. The first buckle plate 31 and the third buckle plate 33 are respectively located on both sides of the second buckle plate 32. The pressing plate 50 is located on the second buckle plate 32. Anti-detachment pieces 51 are provided on both the first buckle plate 31 and the third buckle plate 33. Please refer to Figures 7 to 8 , the anti-detachment pieces 51 on the first buckle plate 31 and the third buckle plate 33 can effectively prevent the vehicle body sheet metal 2 clamped between the pressing plate 50 and the bottom plate 30 from detaching in the reverse direction, increasing the fastening effect on the vehicle body sheet metal 2.

[0043] In an alternative embodiment, the first buckle plate 31, the second buckle plate 32, and the third buckle plate 33 are foldably connected to the connecting edge 300 through a first arc-shaped corner 6. Please refer to Figures 7 to 8 , the arc-shaped structure formed by the first arc-shaped corner 6 not only eliminates stress concentration, but also generates a downward pressure on the side of the first buckle plate 31, the second buckle plate 32, and the third buckle plate 33 away from the connecting edge 300, increasing the stability of the first buckle plate 31, the second buckle plate 32, and the third buckle plate 33 for clamping the vehicle body sheet metal 2.

[0044] In an alternative embodiment, grooves 34 are provided on the inner sides of both the first buckle plate 31 and the second buckle plate 32. The anti-detachment pieces 51 are connected to the side walls of the grooves 34 away from the connecting edge 300. The ends of the anti-detachment pieces 51 are pointed. The anti-detachment pieces 51 extend toward the connecting edge 300 and are simultaneously pressed downward toward the bottom plate 30. Please refer to Figures 7 to 8 , when the vehicle vibrates, the anti-detachment pieces 51 vibrate slightly to produce a "ratchet effect", preventing the vehicle body sheet metal 2 from retracting, effectively increasing the fastening effect on the vehicle body sheet metal 2. The grooves 34 provide the required space for the vertical movement of the anti-detachment pieces 51. In an alternative embodiment, on the sides of the pressing plate 50, the first buckle plate 31, and the second buckle plate 32 away from the connecting edge 300, first flared plates 35 extending away from the bottom plate 30 are provided. On the side of the bottom plate 30 away from the connecting edge 300, a second flared plate 52 extending away from the buckle body 3 is provided. Please refer to Figures 7 to 8 , the first flared plate 35 and the second flared plate 52 form a flared structure, facilitating the guiding of the vehicle body sheet metal 2 to pass through the flared opening and into the clamping space formed by the pressing plate 50, the first buckle plate 31, the second buckle plate 32, and the bottom plate 30.

[0045] In an alternative embodiment, the second buckle plate 32 includes a transition plate 320 connected to the first arc-shaped corner 6, a first clamping plate 321 and a second clamping plate 322 that are oppositely arranged and connected by a second arc-shaped corner 323. The first clamping plate 321 is bent and connected to the transition plate 320, and a pressing plate 50 is bent and connected to the second clamping plate 322. Anti-detachment elastic pieces 400 are provided on both the first clamping plate 321 and the second clamping plate 322, and a relief opening 324 is located on the displacement path of the anti-detachment elastic pieces 400. As Figures 7 to 8 shown, the relief opening 324 can provide the required relief space for the anti-detachment elastic pieces 400 when the anti-detachment elastic pieces 400 are squeezed and move towards the clamping body 40.

[0046] Among them, please refer to Figures 7 to 8 . Two anti-detachment elastic pieces 400 are symmetrically arranged on both sides of the clamping body 40. After the mounting hole 10 is clamped between the two anti-detachment elastic pieces 400, the pressing plate 50, and the transition plate 320, the two anti-detachment elastic pieces 400 respectively abut against the two side edges of the mounting hole 10, increasing the limiting effect on the upper edge of the rear door lower trim panel 1.

[0047] In an alternative embodiment, reinforcing ribs 325 are provided on the plate walls of the first clamping plate 321 and the second clamping plate 322 on both sides of the relief opening 324. As Figures 7 to 8 shown, the reinforcing ribs 325 are beneficial to increasing the structural stability of the first clamping plate 321 and the second clamping plate 322.

[0048] In an alternative embodiment, the length of the second arc-shaped corner 323 at the connection with the first clamping plate 321 and the second clamping plate 322 is the same as the lengths of the first clamping plate 321 and the second clamping plate 322, and the main length of the second arc-shaped corner 323 gradually decreases in the direction away from the bottom plate 30. Please refer to Figures 7 to 8 . The tapered design of the second arc-shaped corner 323 is beneficial to guiding the installation of the mounting hole 10 and reducing the installation difficulty of the mounting hole 10.

[0049] In an alternative embodiment, the rear door lower trim panel 1 includes a first trim panel 11 and a clamping member 12 located at the upper edge of the first trim panel 11. The first trim panel 11 includes a first sub-panel 110 and a second sub-panel 111 that are bent and connected. The clamping member 12 includes a connecting plate 120 connected to the first sub-panel 110. The connecting plate 120 is arranged opposite to the second sub-panel 111 to leave a space required for the clamping body 40 to be clamped into the mounting hole 10. The mounting hole 10 is opened on the connecting plate 120 for positioning. As Figures 1 to 3As shown, the first sub-board 110 and the second sub-board 111 are bent and connected at the connection part through an arc structure to increase the stability of the first sub-board 110 and the second sub-board 111 at the connection part.

[0050] In an alternative embodiment, the clamping member 12 further includes two reinforcing plates 121 respectively connected between two opposite sides of the connecting plate 120 and the first decorative plate 11. As Figures 1 to 2 and Figure 6 shown, the two reinforcing plates 121 not only play a role in stably supporting both sides of the connecting plate 120, but also form a cavity structure among the two reinforcing plates 121, the connecting plate 120 and the first decorative plate 11, which is also beneficial to noise reduction and further structural enhancement.
