Detailed implementation manners

[0029] To make the objectives, technical solutions, and advantages of the embodiments of the present application clearer, the following will clearly and completely describe the technical solutions in the embodiments of the present application with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are some, but not all, of the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present application.

[0030] The embodiment of the present application provides a rear bumper buffer system, which can solve the problem that in order to match the trunk buffer block with the rear bumper, some metal components are exposed outside the rear bumper, affecting the aesthetics of the vehicle.

[0031] As Figures 1 to 5 shown, a rear bumper buffer system includes a rear bumper 1 and a buffer device 2.

[0032] Among them, the rear bumper 1 has a groove 11, and the groove 11 is used to dock with the trunk buffer block 3 located on the back door 4 of the vehicle.

[0033] The buffer device 2 is located inside the rear bumper 1. The buffer device 2 is snap-connected to the inner wall of the rear bumper 1 and is attached to the back surface of the groove 11. The buffer device 2 is used to be fixedly connected to the rear connection plate 5 of the vehicle.

[0034] Specifically, in the embodiment of the present application, the number of the above-mentioned grooves 11 is two, and the two grooves 11 are symmetrically arranged along the transverse direction of the vehicle on the left and right sides of the rear bumper 1. Each groove 11 is a cylindrical structure, and the bottom surface of each groove 11 is a smooth surface. Two trunk buffer blocks 3 are built in the back door 4 of the vehicle. When the back door 4 of the vehicle is in the closed state, the two trunk buffer blocks 3 just dock with the two grooves 11, and one trunk buffer block 3 corresponds to one groove 11.

[0035] Specifically, the above-mentioned buffer device 2 is located inside the rear bumper 1, that is, on the side away from the back door 4. The inner wall of the above-mentioned rear bumper 1 refers to the wall away from the back door 4. In the embodiment of the present application, the number of the grooves 11 is two, and the number of the buffer devices 2 is also two, and one buffer device 2 is attached to the back surface of one groove 11, and the positional relationship is one-to-one correspondence.

[0036] Furthermore, the buffer device 2 includes a buffer plate 21. The buffer plate 21 is snap-connected to the inner wall of the rear bumper 1, and the buffer plate 21 is used to be fixedly connected to the rear connection plate 5. The buffer plate 21 has an arched portion 211 arched towards the rear bumper 1, and the arched portion 211 is used to form a hollow area with the rear connection plate 5.

[0037] Specifically, a hollow area is formed between the arched portion 211 of the above-mentioned buffer plate 21 and the rear connection plate 5 of the vehicle. When the back door 4 is closed, the trunk buffer block 3 impacts the groove 11, generating an impact force. The impact force acts on the buffer plate 21 of the buffer device 2 through the groove 11. At the position of the above-mentioned hollow area, the impact force can be buffered, avoiding all the impact forces acting on the rear connection plate 5, thereby playing a role in protecting the rear connection plate 5. At the same time, it also plays a role in protecting the buffer plate 21 of the buffer device 2. The size of the above-mentioned hollow area can be determined according to the actual situation.

[0038] Specifically, in the embodiment of the present application, the number of the buffer devices 2 is two, and a hollow area exists between each buffer device 2 and the rear connection plate 5. The above-mentioned buffer plate 21 can be a groove-shaped structure, a J-shaped structure, etc.

[0039] Further, the buffer device 2 further includes a buffer pad 22. The buffer pad 22 is located between the rear bumper 1 and the buffer plate 21. One side of the buffer pad 22 is attached to the back surface of the groove 11, and the other side has a protrusion 221 for being clamped to the arched portion 211.

[0040] Specifically, when the rear door 4 is closed, the trunk buffer block 3 impacts the groove 11, generating an impact force. The impact force acts on the buffer pad 22 of the buffer device 2 through the groove 11. The buffer pad 22 can absorb a part of the impact force, playing a role in alleviating, and avoiding all the impact forces acting on the buffer plate 21, thus protecting the buffer plate 21 and the rear connecting plate 5. At the same time, the buffer pad 22 can prevent a gap from being generated between the groove 11 and the buffer plate 21 during assembly, avoiding abnormal noise when the trunk buffer block 3 impacts the groove 11 and the groove 11 directly impacts the buffer plate 21, effectively preventing the paint layer of the rear bumper 1 from being damaged, and having both functionality and aesthetics.

[0041] Specifically, in the embodiment of the present application, the bottom surface of the groove 11 is circular, and the buffer pad 22 is also circular. And preferably, the centers of the bottom surface of the groove 11 and the buffer pad 22 are located on the same straight line to ensure uniform force on the buffer pad 22. And in order to avoid the bottom surface of the groove 11 directly contacting the buffer plate 21, the area of the buffer pad 22 should be equal to the area of the bottom surface of the groove 11.

[0042] Further, the buffer plate 21 further includes two flat plate portions 212. The two flat plate portions 212 are located on opposite sides of the arched portion 211, and the arched portion 211 and the two flat plate portions 212 form a U-shaped structure.

[0043] Specifically, in the embodiment of the present application, the two flat plate portions 212 of the buffer plate 21 are fixedly connected to the rear connecting plate 5, which can increase the contact area between the buffer plate 21 and the rear connecting plate 5, thereby ensuring the connection firmness between the buffer plate 21 and the rear connecting plate 5. The area of the flat plate portion 212 can be determined according to the actual situation.

[0044] Further, a buckle 6 is provided on one side of the rear bumper 1 facing the buffer device 2. The buffer plate 21 has a clamping hole 213, and the buckle 6 is clamped in the clamping hole 213.

[0045] Specifically, in the embodiment of the present application, the number of buckles 6 is two, and the two buckles 6 are respectively located on the upper and lower sides of the back surface of the groove 11. Correspondingly, the arched portion 211 of the buffer plate 21 has two clamping holes 213. When the buffer plate 21 is clamped to the rear bumper 1, the two buckles 6 are respectively clamped to the two clamping holes 213, and one buckle 6 corresponds to one clamping hole 213. The connection method of the rear bumper 1 and the buffer plate 21 through the buckle 6 has a simple structure, is convenient for installation, can increase the connection speed, and does not damage the overall structure of the rear bumper 1.

[0046] Furthermore, on one side of the rear bumper 1 facing the buffer device 2, there is also provided a guiding rib 7 for guiding the buckle 6. The first end of the guiding rib 7 is connected to the rear bumper 1, and the second end extends towards the direction of the buffer plate 21.

[0047] Specifically, the guiding rib 7 is conducive to the quick and accurate engagement of the buckle 6 with the engaging hole 213 to avoid deviation, thereby improving the engagement rate. In the embodiment of the present application, one guiding rib 7 is provided on each of the left and right sides of each buckle 6. The two guiding ribs 7 clamp the buckle 6 in the middle. On the one hand, the guiding rib 7 plays a role in strengthening the structure. On the other hand, the guiding rib 7 can prevent the buckle 6 from moving randomly. When the buckle 6 is engaged with the engaging hole 213, the bottom surface of the upper guiding rib 7 just abuts against the top surface of the arched portion 211 of the buffer plate 21, and the top surface of the lower guiding rib 7 just abuts against the bottom surface of the arched portion 211 of the buffer plate 21.

[0048] Specifically, in the embodiment of the present application, the end of the second end of each guiding rib 7 has an inclined slope. Among them, the slope of each upper guiding rib 7 is located at the lower part of the guiding rib 7, that is to say, the slope is inclined from the end of the second end towards the first end from top to bottom. The slope of each lower guiding rib 7 is located at the upper part of the guiding rib 7, that is to say, the slope is inclined from the end of the second end towards the first end from bottom to top. When the buckle 6 is engaged with the engaging hole 213, the slope of each guiding rib 7 first contacts the buffer plate 21, and the slope can accelerate the matching connection between the buckle 6 and the engaging hole 213.

[0049] Furthermore, the buffer pad 22 further includes a flat portion 222. The protruding portion 221 of the buffer pad 22 includes two elastic blocks. One end of the two elastic blocks is connected to each other, and this end of the two elastic blocks is connected to the flat portion 222. The other ends of the two elastic blocks open towards the direction away from the flat portion 222 to form an opening, and the opening faces the inserting direction of the protruding portion 221.

[0050] Specifically, in the embodiment of the present application, the arched portion 211 has a through hole. The buffer pad 22 includes a flat portion 222 and a protruding portion 221. The structure of the protruding portion 221 includes two elastic blocks. When the protruding portion 221 is engaged with the arched portion 211, the size of the opening of the protruding portion 221 can be changed. By pressing the mutually opening ends of the two elastic blocks, first insert the protruding portion 221 into the through hole of the arched portion 211 in a state of a small opening. Under the action of elastic force, the ends of the two elastic blocks will open in opposite directions, and the opening of the protruding portion 221 automatically becomes larger. The buffer pad 22 will not move towards the direction of the rear bumper 1, thereby ensuring that the buffer pad 22 is tightly connected to the buffer plate 21 and will not separate.

[0051] Further, in the embodiment of the present application, two bumps are further provided on the inner wall of the rear bumper 1. One bump is located above the back of the groove 11, and the other bump is located below the back of the groove 11. The positions of the two bumps correspond up and down. Two buckles 6 are respectively arranged on the two bumps. At the same time, the guiding ribs 7 on both sides of each buckle 6 are also connected to the bumps. The bumps can not only play a role in stabilizing and strengthening the structure of the groove 11, but also provide support for the roots of the buckles 6 and the guiding ribs 7 to ensure the strength of the buckles 6 and the guiding ribs 7. In addition, each bump has a doghouse structure, similar to a cardboard box with an opening, which can prevent other structures from directly contacting the inner bumper 1 and generating injection molding shrink marks.

In the embodiment of the present application, the number of the grooves 11 is two, and the number of the buffer devices 2 is also two, and one buffer device 2 is attached to the back of one groove 11, and the positional relationship is one-to-one correspondence.

[0060] Specifically, the number of the above-mentioned grooves 11 is two, and the two grooves 11 are symmetrically arranged along the transverse direction of the vehicle on the left and right sides of the rear bumper 1. Each groove 11 is a cylindrical structure, and the bottom surface of each groove 11 is a smooth surface. Two trunk buffer blocks 3 are built in the rear door 4 of the vehicle.

[0061] Furthermore, the buffer device 2 includes a buffer plate 21, the buffer plate 21 is snap-connected to the inner wall of the rear bumper 1, and the buffer plate 21 has a arched portion 211 arched towards the rear bumper 1, and the arched portion 211 and the rear connecting plate 5 form a hollow area.

[0062] Specifically, a hollow area is formed between the arched portion 211 of the above-mentioned buffer plate 21 and the rear connecting plate 5 of the vehicle. The impact force generated by the trunk buffer block 3 hitting the groove 11 can be buffered, avoiding all the impact forces acting on the rear connecting plate 5, thereby playing a role in protecting the rear connecting plate 5.

[0064] Furthermore, the above-mentioned buffer device 2 further includes a buffer pad 22. The buffer pad 22 is located between the rear bumper 1 and the buffer plate 21. One side of the buffer pad 22 is attached to the back surface of the groove 11, and the other side has a protrusion 221 for being clamped in the arched portion 211. When the rear door 4 is closed, the trunk buffer block 3 impacts the groove 11 to generate an impact force. The impact force acts on the buffer pad 22 of the buffer device 2 through the groove 11. The buffer pad 22 can absorb a part of the impact force, playing a role in alleviating, and avoiding all the impact forces acting on the buffer plate 21, thereby protecting the buffer plate 21 and the rear connecting plate 5.
