[0030] Embodiment:

[0031] As Figure 1 - 8 shows, this embodiment proposes an automotive trunk shock-absorbing assembly for connecting in the mounting hole 40 of an automotive sheet metal, including a connecting rod 10, and the connecting rod 10 is arranged in the mounting hole 40;

[0032] A shock-absorbing sleeve 20 is arranged on the connecting rod 10, a limiting plate 16 is arranged on the connecting rod 10, multiple groups of positioning holes 15 are opened on the limiting plate 16, a limiting cavity 25 is arranged on the shock-absorbing sleeve 20, the limiting plate 16 is arranged in the limiting cavity 25, multiple groups of positioning rods 22 are further arranged in the limiting cavity 25, the positions of the multiple groups of positioning rods 22 match those of the multiple groups of positioning holes 15, and the positioning rods 22 are arranged in the positioning holes 15 by injection molding, so that the shock-absorbing sleeve 20 is positioned on the connecting rod 10.

[0033] In this embodiment, through the cooperation between the arranged positioning holes 15 and positioning rods 22, the shock-absorbing sleeve 20 can be effectively positioned on the outer wall of the connecting rod 10, and the positioning rods 22 are connected in the positioning holes 15 by injection molding process, which can greatly improve the connection stability, and only injection molding is required during assembly, greatly improving the overall practicability. After the shock-absorbing sleeve 20 is installed, it can prevent the shock-absorbing sleeve 20 from detaching from the connecting rod 10 and affecting the normal shock-absorbing process.

[0034] Specifically, a fixing plate 14 is further provided on the connecting rod 10;

[0035] A fixing cavity 23 is formed in the shock-absorbing sleeve 20, and the fixing plate 14 is arranged in the fixing cavity 23.

[0036] In this embodiment, by the adaptation of the fixing plate 14 and the fixing cavity 23, the connection stability between the shock-absorbing sleeve 20 and the connecting rod 10 can be further improved.

[0037] Specifically, reinforcing ribs 13 are provided on the fixing plate 14;

[0038] A reinforcing cavity 24 is arranged in the shock-absorbing sleeve 20, the reinforcing cavity 24 is arranged between the fixing cavity 23 and the limiting cavity 25, and the reinforcing ribs 13 are arranged in the reinforcing cavity 24.

[0039] In this embodiment, by providing the reinforcing ribs 13, the contact area between the shock-absorbing sleeve 20 and the connecting rod 10 can be increased, making their combination stronger. At the same time, the connection stability between the limiting plate 16 and the fixing plate 14 can also be improved, preventing the limiting plate 16 from breaking off the connecting rod 10.

[0040] Specifically, an injection hole 17 is formed in the fixing plate 14, a guide post 21 is arranged in the injection hole 17, and the guide post 21 and the shock-absorbing sleeve 20 are of an integrally formed structure;

[0041] The injection hole 17 guides the flow of injection material to wrap around the limiting plate 16 to form the shock-absorbing sleeve 20.

[0042] Specifically, a plurality of groups of elastic shock-absorbing balls 30 are provided on the shock-absorbing sleeve 20, and the elastic shock-absorbing balls 30 are made of TPE material.

[0043] In this embodiment, when producing the shock-absorbing sleeve 20, a mold adapted to the shock-absorbing sleeve 20 and the elastic shock-absorbing balls 30 is prepared. Then, the connecting rod 10 is placed in the mold, and the injection material is introduced into the mold through the injection hole 17 to form the shock-absorbing sleeve 20 and the elastic shock-absorbing balls 30 in the mold, so that the positioning rod 22 on the shock-absorbing sleeve 20 is placed in the positioning hole 15;

[0047] An elastic buckle 121 is arranged in the movable through groove 12. The elastic buckle 121 extends into the mounting hole 40, so that the connecting rod 10 is fixed in the mounting hole 40.

[0048] In this embodiment, by arranging the elastic buckle 121, it is convenient to install the connecting rod 10 in the mounting hole 40 of the automobile sheet metal. When the automobile trunk contacts the shock-absorbing sleeve 20, energy absorption and shock absorption are carried out through the shock-absorbing sleeve 20 and the elastic shock-absorbing ball 30.

[0049] Specifically, the shock-absorbing sleeve 20, the positioning rod 22 and the guide post 21 are of an integrally formed structure, and the shock-absorbing sleeve 20, the positioning rod 22 and the guide post 21 are made of TPE material;

[0050] The connecting rod 10 is made of PA66 material.

[0051] In this embodiment, during injection molding, other components made of non-TPE materials (such as the connecting rod 10 made of PA66 material) can be prepared in the mold first, and then TPE material is injected onto the previously prepared components to prepare the elastic shock-absorbing ball 30 and the shock-absorbing sleeve 20.

[0052] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
