Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0017] Example: Figure 1-4 As shown, the utility model provides a reinforced connection assembly for automobile shell plastic parts, including a bumper shell body 1, one end of the bumper shell body 1 is provided with an adjustment assembly 3, one end of the adjustment assembly 3 is fixedly connected to two reinforcement assemblies 2, the reinforcement assembly 2 includes a support frame 21, the inner walls on both sides of the support frame 21 are commonly fixedly connected with a horizontal plate 24, one end of the horizontal plate 24 is hinged with four first connection plates 25 through a rotating shaft, the inner walls on both sides of the support frame 21 are fixedly connected with two vertical plates 22, and one end of the four vertical plates 22 is hinged with a matching first connection plate 25 through a rotating shaft. The connecting plate 25 uses a second connecting plate 26, and the corresponding ends of the opposite surfaces of the first connecting plate 25 and the second connecting plate 26 are fixedly connected with a damper body 23. When the outside of the bumper shell body 1 is impacted, the two support frames 21 can play a certain supporting role on the bumper shell body 1 through the reinforcement component 2, so as to prevent the bumper shell body 1 from being damaged when it is hit. At the same time, the damper body 23 structure is arranged inside the support frame 21, so that the support frame 21 can have a buffering force when supporting, so that the use strength of the bumper shell body 1 is better.

[0018] The adjustment component 3 includes a connecting frame 39, one end of which is fixedly connected to the inner wall of one side of the bumper shell body 1, a through slot 38 is provided at the top of the connecting frame 39, a motor 37 is fixedly connected to the inner wall of the through slot 38, and a first bevel gear 34 is fixedly connected to the output end of the motor 37, the outer surface of the first bevel gear 34 is meshedly connected to the second bevel gear 33, the inner walls of both sides of the connecting frame 39 are commonly fixedly connected to a bidirectional screw 35, and the second bevel gear 33 is fixedly sleeved on the outer surface of the bidirectional screw 35, and the outer surface of the bidirectional screw 35 is respectively threadedly sleeved with the first moving block 301 and the second bevel gear 33. Two moving blocks 36, and one end of the first moving block 301 and the second moving block 36 are respectively fixedly connected to one end of the two supporting frames 21, and the motor 37 is started. The output end of the motor 37 drives the first bevel gear 34 to rotate, and the rotation of the first bevel gear 34 drives the second bevel gear 33 to rotate, and the rotation of the second bevel gear 33 drives the bidirectional screw 35 to rotate. The rotation of the bidirectional screw 35 drives the first moving block 301 and the second moving block 36 to move, and the movement of the first moving block 301 and the second moving block 36 respectively drives the two supporting frames 21 to move, so that the positions of the two reinforcement components 2 are fine-tuned to facilitate the installation of the bumper shell body 1.

[0019] The two corresponding damper bodies 23 are distributed in a mirror image, which facilitates the coordinated use of the two corresponding damper bodies 23 so that the damper bodies 23 can better reduce the amplitude of the support frame 21 .

[0020] The internal structures of the two reinforcement components 2 are arranged in the same manner, so that the two reinforcement components 2 can be used in coordination with each other.

[0021] The inner walls on both sides of the connecting frame 39 are respectively fixedly connected with two guide rods 31 used in conjunction with the first moving block 301 and the second moving block 36, and the first moving block 301 and the second moving block 36 are respectively slidably sleeved on the outer surfaces of the two corresponding guide rods 31, so as to facilitate the guiding and limiting function of the guide rods 31 on the first moving block 301 and the second moving block 36 when moving, thereby preventing the first moving block 301 and the second moving block 36 from rotating with the bidirectional screw 35.

[0022] The ends of the four guide rods 31 facing away from the inner wall of the connecting frame 39 are fixedly connected with a limiting plate 32 used for cooperating with the first moving block 301 and the second moving block 36. The limiting plate 32 serves to facilitate limiting the moving position of the first moving block 301 and the second moving block 36.

[0023] The first moving block 301 and the second moving block 36 are respectively threadedly sleeved on different thread directions of the outer surface of the bidirectional screw 35, so as to facilitate the first moving block 301 and the second moving block 36 to move toward opposite sides or back to back sides when moving.

[0024] The first bevel gear 34 and the second bevel gear 33 are vertically arranged, and the outer surface tooth shapes of the first bevel gear 34 and the second bevel gear 33 match each other, so that the first bevel gear 34 and the second bevel gear 33 are convenient for coordinated use.

[0025] Working principle: First, the motor 37 is started by adjusting the component 3, and the output end of the motor 37 drives the first bevel gear 34 to rotate, and the rotation of the first bevel gear 34 drives the second bevel gear 33 to rotate, and the rotation of the second bevel gear 33 drives the bidirectional screw 35 to rotate, and the rotation of the bidirectional screw 35 drives the first moving block 301 and the second moving block 36 to move, and at the same time, the guide rod 31 guides and limits the first moving block 301 and the second moving block 36 when they move, so as to prevent the first moving block 301 and the second moving block 36 from rotating with the bidirectional screw 35, and the limit plate 32 plays a role in facilitating the position limitation of the first moving block 301 and the second moving block 36, and the movement of the first moving block 301 and the second moving block 36 respectively drives the two support frames 21 to move, so that the positions of the two reinforcing components 2 are fine-tuned, so that the two reinforcing components 2 are adjusted to a position convenient for installing the bumper shell body 1;

[0026] Then the bumper shell body 1 is installed on the corresponding car;

[0027] When the surface of the bumper shell body 1 is impacted, the two support frames 21 can provide certain support to the bumper shell body 1 through the reinforcing component 2, thereby preventing the bumper shell body 1 from being damaged when it is impacted. At the same time, the damper body 23 structure connected by the first connecting plate 25 and the second connecting plate 26 inside the support frame 21 can enable the support frame 21 to have a buffering force when supporting, thereby making the bumper shell body 1 stronger in use.

[0028] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
