[0032] Reference below Figure 1-Figure 4 The mounting structure 100 of the rear door limit block according to the embodiment of the utility model is described. The mounting structure 100 of the rear door limit block has high strength and rigidity, thereby improving the mounting rigidity and strength of the rear door limit block, and reducing the stamping process of the mounting structure 100, thereby improving production efficiency and reducing production costs. At the same time, it is conducive to the clamping of the welding fixture, and can stably perform welding points on the main panel 1, which is easy to operate and has high reliability.

[0033] like Figure 1-Figure 4 As shown, according to the mounting structure 100 of the back door limit block according to the embodiment of the utility model, the mounting structure 100 includes a main body plate 1 and a reinforcing flange 2.

[0034] The main body panel 1 is suitable for being attached and connected to the rear door inner panel 300 , and the main body panel 1 has a connecting portion 24 for connecting to the rear door stop block.

[0035] Specifically, one side surface of the main body panel 1 is connected to the inner side surface of the back door inner panel 300 to increase the contact area between the main body panel 1 and the back door inner panel 300, thereby improving the connection strength between the two, and further improving the connection stability and reliability between the back door stop block and the back door inner panel 300. The main body panel 1 is provided with a through hole that passes through the front and back, namely, a connecting portion 24, and the back door inner panel 300 is also provided with a corresponding through hole, and the size and shape of the connecting portion 24 and the size and shape of the through hole on the back door inner panel 300 are adapted to the size and shape of the connecting member 200, so that the connecting member 200 can pass through the back door inner panel 300 and the main body panel 1 in sequence to connect the back door stop block to the main body panel 1, and the connecting member 200 can be a bolt, etc.

[0036] The reinforcing flange 2 is connected to the edge of the main body panel 1 , and the reinforcing flange 2 is configured to be bent relative to the main body panel 1 toward a side away from the rear door inner panel 300 .

[0037] That is, the outer edge of the main body plate 1 is bent and extended for a distance toward the side away from the back door inner plate 300 to form a reinforcing flange 2. The reinforcing flange 2 can improve the rigidity and strength of the mounting structure 100, thereby improving the installation rigidity and strength of the back door stopper, while the weight and cost of the mounting structure 100 are not increased, and the reliability is high. In addition, the reinforcing flange 2 can reduce the stamping process of the mounting structure 100, improve production efficiency, and reduce production costs.

[0038] In addition, welding points can be made on the main body panel 1 to further connect it to the tailgate inner panel 300 through the welding points, which can further increase the connection strength between the mounting structure 100 and the tailgate inner panel 300, strengthen the setting of the flange 2, and facilitate the clamping of the welding fixture, that is, when making welding points, the welding fixture can be clamped on the reinforced flange 2 to prevent the welding fixture from falling off easily, so that welding points can be stably made on the main body panel 1, which is convenient for operation.

[0039] It should be noted that the mounting structure 100 of the rear door limit block is used to install the rear door limit block on the rear door inner panel 300, wherein the rear door limit block can limit the rear door to prevent the rear door from shaking, being unstable, and being opened and closed excessively when closed, thereby causing damage to the rear door.

[0040] According to the mounting structure 100 of the rear door limit block of the embodiment of the utility model, by setting a reinforcing flange 2 at the edge of the main plate 1, the mounting structure 100 of the rear door limit block can be optimized as a whole, the rigidity and strength of the mounting structure 100 are improved, thereby improving the mounting rigidity and strength of the rear door limit block, and the stamping process of the mounting structure 100 can be reduced, thereby improving production efficiency and reducing production costs. At the same time, it is conducive to the clamping of the welding fixture, and the welding points can be stably performed on the main plate 1, which is easy to operate and has high reliability.

[0041] In some embodiments, there are two reinforcing flanges 2, and at least a portion of the two reinforcing flanges 2 are relatively distributed along the first direction, that is, the two reinforcing flanges 2 can be relatively distributed along the first direction in part or in whole, and at least another portion of the two reinforcing flanges 2 are relatively distributed along the second direction, that is, the two reinforcing flanges 2 can be relatively distributed along the second direction in part or in whole.

[0042] The first direction intersects with the second direction, and the first direction and the second direction can be respectively the up-down direction, the left-right direction or other intersecting directions. That is to say, by arranging the two reinforcing flanges 2 to be relatively distributed in different directions, the mounting structure 100 can be reinforced in different directions, thereby improving its strength and rigidity in different directions, thereby further improving the life of the mounting structure 100.

[0043] like Figure 1-Figure 3As shown, two reinforcing flanges 2 are provided on the main body panel 1, and the two reinforcing flanges 2 are bent and extended along the periphery of the main body panel 1 toward a side away from the tailgate inner panel 300, and a portion of the two reinforcing flanges 2 are relatively distributed along a first direction to reinforce the mounting structure 100 in the first direction and improve the strength and stiffness of the mounting structure 100 in the first direction, and another portion of the two reinforcing flanges 2 are relatively distributed along a second direction to reinforce the mounting structure 100 in the second direction and improve the strength and stiffness of the mounting structure 100 in the second direction.

[0044] In some embodiments, the first direction is perpendicular to the second direction, and / or the first direction is along the vertical direction of the vehicle, and the second direction is along the longitudinal direction of the vehicle.

[0045] That is, the first direction may be the up-down direction, i.e., the vertical direction of the vehicle, and the second direction may be the front-back direction, i.e., the longitudinal direction of the vehicle. Figure 3 and Figure 4 As shown, a portion of the two reinforcing flanges 2 can be relatively distributed along the up-down direction as shown in the figure, and another portion of the two reinforcing flanges 2 can be relatively distributed along the left-right direction as shown in the figure, thereby achieving reinforcement of the mounting structure 100 in the up-down direction and the left-right direction, improving its strength and rigidity in the up-down direction and the left-right direction. In other words, improving its strength and rigidity in the up-down direction and the front-rear direction relative to the vehicle, and the portions of the two reinforcing flanges 2 relatively distributed in the first direction and the second direction can reinforce each other, further improving the reinforcement effect.

[0046] In some embodiments, the two reinforcing flanges 2 are distributed in a centrally symmetrical manner, that is, the two reinforcing flanges 2 are distributed in a centrally symmetrical manner along the center of the main body plate 1, so that the installation structure 100 is subjected to uniform force.

[0047] Specifically, Figure 3 and Figure 4 As shown, the two reinforcing flanges 2 are identical and are symmetrically distributed around the two diagonals of the main board along the center of the main board 1. As shown in the up and down and left and right directions in the figure, a portion of the first reinforcing flange 2 is located on the upper side and the other portion is located on the left side, a portion of the second reinforcing flange 2 is located on the lower side and the other portion is located on the right side, and the two portions of the first reinforcing flange 2 and the second reinforcing flange 2 are smoothly connected on the periphery of the main board 1 through a transition fillet, which can further improve the strength and durability of the mounting structure 100 and reduce the risk of breakage, thereby improving the life of the mounting structure 100 and reducing costs.

[0048] In some embodiments, the reinforced flange 2 includes a first reinforcement segment 21 and a second reinforcement segment 22, the first reinforcement segment 21 and the second reinforcement segment 22 are connected in sequence along the circumference of the main plate 1, and the height of the first reinforcement segment 21 protruding from the main plate 1 is greater than the height of the second reinforcement segment 22 protruding from the main plate 1.

[0049] Specifically, Figure 4 As shown, the reinforced flange 2 is composed of a first reinforced segment 21 and a second reinforced segment 22. The first reinforced segment 21 and the second reinforced segment 22 are smoothly connected in sequence along the circumference of the main plate 1 through transition fillets. The height of the first reinforced segment 21 protruding from the main plate 1 is greater than the height of the second reinforced segment 22 protruding from the main plate 1. This arrangement can avoid wrinkling of the first reinforced segment 21 and the second reinforced segment 22 at the corner connection of the main plate 1, that is, they can be smoothly connected to prevent fatigue cracking problems, thereby further improving the life of the mounting structure 100.

[0050] In actual design, the height of the second reinforcement section 22 protruding from the main plate 1 can be set to be 2 mm less than the height of the first reinforcement section 21 protruding from the main plate 1. Of course, it can also be set to other heights and can be flexibly adjusted according to actual conditions and needs. It is not limited to what is described in this embodiment. It only needs to meet the requirement that the height of the first reinforcement section 21 protruding from the main plate 1 is greater than the height of the second reinforcement section 22 protruding from the main plate 1.

[0051] In some embodiments, the main body plate 1 is constructed as a rectangular plate, the first reinforcement section 21 is connected to the long side of the main body plate 1, and the second reinforcement section 22 extends from the long side of the main body plate 1 to the short side of the main body plate 1, that is, the first reinforcement section 21 can be constructed as a straight section to extend in a straight line at the edge of the long side of the main body plate 1, and the second reinforcement section 21 can be constructed to be at least partially arc-shaped, and the second reinforcement section 21 extends toward the long side and short side of the main body plate 1 at the corner. In this way, the main body 1 can be shortened by 2mm at the corner flange to avoid corner wrinkling and fatigue cracking.

[0052] like Figure 3 As shown, the main body panel 1 is constructed as a rectangular plate, the length direction of the rectangular plate is the vertical direction of the vehicle, the width direction is the longitudinal direction of the vehicle, and the four top corners of the rectangular plate are all rounded to reduce stress concentration. As shown in the up and down and left and right directions in the figure, the first reinforcement section 21 of the first reinforcement flange 2 is a part on the upper left side, and the second reinforcement section 22 is connected to the first reinforcement section 21 and extends from the upper left side to the upper side. The first reinforcement section 21 of the second reinforcement flange 2 is a part on the lower right side, and the second reinforcement section 22 is connected to the first reinforcement section 21 and extends from the lower right side to the lower side.

[0053] In some embodiments, a reinforcing rib 23 is formed at the connection between the reinforcing flange 2 and the main plate 1. The reinforcing rib 23 can increase the strength and rigidity of the connection between the reinforcing flange 2 and the main plate 1 to prevent it from breaking.

[0054] Specifically, Figure 2-Figure 4As shown, the reinforcing rib 23 is provided at the connection between the first reinforcing section 21 and the main body panel 1, and the connection between the two reinforcing flanges 2 and the main body panel 1 is provided with reinforcing ribs 23. Thus, the left and right sides of the main body panel 1 are provided with reinforcing ribs 23, and the two reinforcing ribs 23 are staggered, which can further increase the strength and rigidity of the connection between the reinforcing flange 2 and the main body panel 1, and make the mounting structure 100 evenly stressed.

[0055] In some embodiments, there are multiple reinforcing flanges 2 , and the multiple reinforcing flanges 2 are distributed at intervals along the circumferential direction at the edge of the main body plate 1 .

[0056] That is, the number of reinforcing flanges 2 can be set to two, three or even more. Setting multiple reinforcing flanges 2 can make the installation structure 100 stronger, and multiple reinforcing flanges 2 are distributed at intervals along the circumference at the edge of the main plate 1, so that multiple circumferential positions of the main plate 1 can be strengthened. For example, four reinforcing flanges 2 can be set on the main plate 1, and the four reinforcing flanges 2 are connected in sequence and distributed at the edge of the main plate 1, so that each circumferential position of the main plate 1 can be strengthened, thereby greatly improving its strength and rigidity.

[0057] In some embodiments, the main body panel 1 and the reinforcing flange 2 are stamped as one piece, that is, only one process is needed to complete the design of the punching and reinforcing flange 2, which reduces the number of process steps and eliminates the need for multiple processes to produce the installation structure 100, thereby improving production efficiency and reducing production costs. The one-piece stamping installation structure 100 is more durable and has better stability.

[0058] The utility model also provides a vehicle.

[0059] According to the vehicle of the embodiment of the utility model, a mounting structure 100 of a tailgate limit block according to any one of the above-mentioned embodiments is provided, the tailgate limit block and the mounting structure 100 are respectively located on the inner and outer sides of the tailgate inner panel 300 and are connected by a connecting member 200, and the connecting member 200 passes through the connecting portion 24 and the tailgate inner panel 300 in sequence to be connected to the tailgate limit block.

[0060] Specifically, Figure 1 As shown, the tailgate limit block and the mounting structure 100 are installed on the flanges on both sides of the tailgate inner panel 300, wherein the tailgate limit block is installed on the outside and the mounting structure 100 is installed on the inside, the connecting member 200 is constructed as a bolt, and the tailgate limit block, the mounting structure 100 and the tailgate inner panel 300 are all provided with bolt through holes of the same size and shape, and the bolts penetrate the connecting portion 24 and the tailgate inner panel 300 from the outside to the inside in sequence to be connected to the tailgate limit block.

[0061] like Figure 2As shown, welding spots can also be made on the outer side surface of the main body panel 1, so that the mounting structure 100 and the tailgate inner panel 300 can be more stably connected through the welding spots, further increasing the connection strength between the mounting structure 100 and the tailgate inner panel 300.

[0062] According to the vehicle of the embodiment of the utility model, by setting a reinforcing flange 2 at the edge of the main body panel 1, the mounting structure 100 of the tailgate limit block can be optimized as a whole, the rigidity and strength of the mounting structure 100 are improved, thereby improving the mounting rigidity and strength of the tailgate limit block, and the stamping process of the mounting structure 100 can be reduced, thereby improving production efficiency and reducing production costs. At the same time, it is conducive to the clamping of the welding fixture, and the welding points can be stably performed on the main body panel 1, which is easy to operate and has high reliability.
