Figure 2 and Figure 3 As shown, the extension block 5 is provided with a second connecting strip 6 in a mirror image on one side facing the support frame 2, and the second connecting strip 6 is welded and fixed to the extension block 5, and the two second connecting strips 6 are both S-shaped, and the support frame 2 is welded with a second connecting block 14 on one side facing the extension block 5, and the upper and lower ends inside the second connecting block 14 are mirror imaged with first grooves 16, and the first groove 16 is connected to the second connecting strip 6 slot. When the support frame 2 is assembled and installed, the second connecting block 14 is clamped on the outside of the extension block 5, and the second connecting strip 6 is inserted into the first groove 16. The S-shaped second connecting strip 6 can improve the impact resistance of the connection position between the support frame 2 and the exterior panel 1, and avoid looseness after connection and assembly;

[0028] In this embodiment, an adapter sheet 7 is provided on one side of the support frame 2 facing the connecting frame 3, and the adapter sheet 7 is welded and fixed to the support frame 2. Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the connecting frame 3 is welded with a first connecting block 8 toward the position of the adapter piece 7, the interior of the first connecting block 8 is provided with a second groove 17, and the exterior of the second groove 17 is connected to the exterior slot of the adapter piece 7. When the connecting frame 3 is assembled and connected, the connecting frame 3 is inserted into the exterior of the adapter piece 7 through the first connecting block 8. The adapter piece 7 is S-shaped, and the S-shaped connection position can bear a large impact force, so as to avoid the connecting frame 3 being unable to be disassembled and replaced after the impact. The combination of the adapter piece 7 and the second groove 17 can improve the impact resistance of the automobile bumper.

[0029] In this embodiment, first connecting bars 4 are provided at both upper and lower ends of one side of the two connecting frames 3, and the first connecting bars 4 are welded and fixed to the connecting frames 3. Figure 1 and Figure 2 As shown, the first connecting strip 4 is S-shaped, and a filling block 13 is provided on one side of the outside of the first connecting strip 4. The filling block 13 fills a part of the S-shaped first connecting strip 4. The filling of the filling block 13 can facilitate the fitting of the front end of the vehicle shell, and facilitate the connection after fitting;

[0030] In this embodiment, a first connecting piece 9 is welded to the middle position of the extension block 5 toward the support frame 2, and a second connecting piece 15 is disposed on one side of each of the two first connecting pieces 9. Figure 3 and Figure 6As shown, the second connecting piece 15 and the second connecting block 14 are an integral structure, the second connecting piece 15 and the first connecting piece 9 are directly penetrated by the first bolt 11, a connecting ring 10 is provided on one side of the outside of the first bolt 11, and the inside of the connecting ring 10 is threadedly matched with the external thread of the first bolt 11, and the connecting ring 10 is located on the other side of the first connecting piece 9, and the first connecting piece 9 and the second connecting piece 15 can be fixed by the penetration of the first bolt 11 and the rotation of the connecting ring 10, and the stability of the connection of the support frame 2 is improved when the second connecting strip 6 and the first groove 16 are connected by the card slot;

[0031] In this embodiment, a pair of second bolts 12 are disposed transversely at the upper end of the fitting position of the adapter piece 7 and the first connecting block 8, and the second bolts 12 penetrate the connecting frame 3 and extend to the inside of the supporting frame 2. Figure 2 As shown, the thread position of the outside of the second bolt 12 matches with the internal thread of the support frame 2, and the connection frame 3 is fixed by the penetration and embedding of the second bolt 12.

[0032] Working principle: when the device is used and the automobile bumper is assembled and installed, the second connecting block 14 connected to the support frame 2 is moved to align with the extension block 5, and the second connecting strip 6 is moved and inserted into the first groove 16. After insertion, the first bolt 11 passes through the second connecting piece 15 and the first connecting piece 9 in sequence, and the connecting ring 10 is rotated from the outside of the first bolt 11 and fits the first connecting piece 9. The threaded cooperation of the first bolt 11 and the connecting ring 10 realizes the fixation of the support frame 2. The connecting frame 3 is inserted into the outer part of the adapter piece 7 through the first connecting block 8. At the same time, the adapter piece 7 is fitted and adapted to the position of the second groove 17. A pair of second bolts 12 pass through the connecting frame 3 and are embedded in the interior of the support frame 2 to realize the fixation of the connecting frame 3. When an impact occurs from the outside, the impact force is borne partly by the connection position of the second connecting strip 6 and the second connecting block 14, and the connection position of the adapter piece 7 and the first connecting block 8 bears another part of the impact force. The S-shaped connection position can improve the fit while avoiding deformation caused by impact.
