[0003] The D-pillar structure is mostly manufactured using sheet metal technology. However, the sheet metal process requires the combination of multiple parts, which will inevitably lead to an increase in the number of D-pillar structure parts, resulting in the D-pillar structure being unable to achieve the lightweight requirement. In order to achieve lightweight manufacturing of the D-pillar structure, in the related art, the D-pillar structure is produced by casting, and the D-pillar structure is produced as a casting structure.

[0004] However, when a D-pillar structure produced by casting is connected to a wheel arch of a vehicle, the connection position between the D-pillar structure and the wheel arch is riveted on one side, and the connection between the D-pillar structure and the wheel arch is weak. Other parts need to be added to enhance the tightness of the connection between the D-pillar structure and the wheel arch, which is bound to increase the weight of the vehicle.

[0048] See also Figure 1 , Figure 2 and Figure 3 . Figure 1 A structural schematic diagram showing a D-pillar structure in an embodiment of the present application applied to a vehicle is shown. Figure 2 Shows Figure 1 A local enlarged schematic diagram of point A in the middle. Figure 3 The structural schematic diagram of the D-pillar structure in an embodiment of the present application is shown. The D-pillar structure 1 provided in an embodiment of the present application includes a column 11 and a matching portion 12. The matching portion 12 is arranged on the column 11, and the matching portion 12 includes a first contact surface 111, a bending surface 112 and a second contact surface 113, the bending surface 112 is connected to the first contact surface 111 and the second contact surface 113, the first contact surface 111, the bending surface 112 and the second contact surface 113 are surrounded to form an open cavity 114, and the first contact surface 111, the bending surface 112 and the second contact surface 113 are used to be connected to the wheel cover 22 of the vehicle 2 together.

[0049] It should be noted that, see Figure 1 and Figure 2 . Figure 1 A structural schematic diagram showing a D-pillar structure in an embodiment of the present application applied to a vehicle is shown. Figure 2 Shows Figure 1A partial enlarged schematic diagram of point A in the middle. The D-pillar structure 1 is located at the connection between the roof and the body 21 of the rear of the vehicle 2. Specifically, the D-pillar structure 1 is connected between the wheel housing 22 and the body 21 of the vehicle 2. The D-pillar structure 1 is an important load-bearing component in the vehicle 2 and needs to withstand the impact force of the vehicle 2. Since the D-pillar structure 1 is located at the rear of the vehicle 2, the D-pillar structure 1 needs to meet certain rigidity and strength requirements to ensure that the vehicle 2 can protect the safety of the occupants when the vehicle 2 is hit from the rear.

[0050] In order to make the D-pillar structure 1 have high rigidity and strength, it is usually manufactured by sheet metal technology. However, the D-pillar structure 1 manufactured by sheet metal cannot be formed into the complex shape required by the specific part of the vehicle 2 at one time, and multiple parts need to be assembled, which will inevitably lead to an increase in the number of D-pillar structures 1 and an increase in the weight of the vehicle 2. Therefore, under the requirement of rigidity and strength required by the D-pillar structure 1, the D-pillar structure 1 is processed into a structure of a casting by casting. Although the number of parts required in the D-pillar structure 1 is greatly reduced, when the D-pillar structure 1 in the related art is connected to the wheel cover 22 of the vehicle 2, the position where the D-pillar structure 1 is connected to the wheel cover 22 is riveted on one side, and additional parts need to be added to enhance the tightness of the connection between the D-pillar structure 1 and the wheel cover 22, so that the D-pillar structure 1 meets the requirements of rigidity and strength during operation. Since additional connecting parts are added between the D-pillar structure 1 and the wheel cover 22, the weight of the vehicle 2 is increased.

[0051] The D-pillar structure 1 in the embodiment of the present application includes a pillar body 11 and a matching portion 12. Figure 3 . Figure 3 The structural schematic diagram of the D-pillar structure in an embodiment of the present application is shown. Since the matching portion 12 is directly arranged on the column 11, it is not necessary to connect the matching portion 12 and the column 11 through additional parts, thereby reducing the weight of the internal structure of the D-pillar structure 1. At the same time, since the first contact surface 111, the bending surface 112 and the second contact surface 113 are surrounded to form an open cavity 114, the first contact surface 111, the bending surface 112 and the second contact surface 113 are used to be connected to the wheel cover 22 of the vehicle 2. In the process of connecting the D-pillar structure 1 with the wheel cover 22, the first contact surface 111, the bending surface 112 and the second contact surface 113 are in contact with the wheel cover 22 in different directions and angles. When the D-pillar structure 1 is subjected to forces in different directions, it can ensure that the D-pillar structure 1 and the wheel cover 22 are tightly connected, and it is not necessary to set additional parts between the D-pillar structure 1 and the wheel cover 22.

[0052] Furthermore, since the D-pillar structure 1 and the wheel housing 22 can be tightly connected only through the structure of the D-pillar structure 1 itself and meet the stiffness and strength requirements of the D-pillar structure 1, there is no need to set additional parts between the D-pillar structure 1 and the wheel housing 22, thereby reducing the external weight of the D-pillar structure 1. At the same time, by directly setting the mating portion 12 on the column 11, the internal weight of the D-pillar structure 1 is reduced, thereby reducing the weight of the vehicle 2, which is beneficial to the lightweight manufacturing of the vehicle 2.

[0053] In addition, during the connection between the D-pillar structure 1 and the wheel arch 22, the first contact surface 111, the bent surface 112 and the second contact surface 113 are contact surfaces with the wheel arch 22 in different directions and angles. When the D-pillar structure 1 is subjected to external force, the first contact surface 111, the bent surface 112 and the second contact surface 113 can generate resistance forces in multiple directions on the D-pillar structure 1, thereby further improving the stiffness and strength of the D-pillar structure 1.

[0054] In addition, during the process of manufacturing the vehicle 2, only the D-pillar structure 1 and the wheel cover 22 need to be connected, and no other parts are required to assist in the connection between the D-pillar structure 1 and the wheel cover 22. On the one hand, the number of parts is reduced, thereby reducing production costs; on the other hand, there is no need to process and produce additional parts, thereby reducing the size chain of the vehicle 2, which is beneficial to size control while reducing production processes, and can improve the efficiency of vehicle 2 production.

[0055] In some embodiments, the bending surface 112 includes a first bending surface 1121 and a second bending surface 1122. Figure 3 . Figure 3 The schematic diagram of the structure of the D-pillar in an embodiment of the present application shows that the first contact surface 111 , the first bending surface 1121 , the second bending surface 1122 and the second contact surface 113 are connected in sequence, and the first bending surface 1121 and the second bending surface 1122 are arranged on the same side of the first contact surface 111 .

[0056] Specifically, since the bending surface 112 includes the first bending surface 1121 and the second bending surface 1122, the connection between the D-pillar structure 1 and the wheel cover 22 can be tightened from different directions through the joint action of the first bending surface 1121 and the second bending surface 1122, so that the connection between the D-pillar structure 1 and the wheel cover 22 is tighter, thereby further improving the rigidity and strength of the D-pillar structure 1. Since the first bending surface 1121 and the second bending surface 1122 are jointly arranged on the same side of the first contact surface 111, the designer only needs to consider the position and structure of one side of the first contact surface 111, which can simplify the design of the designer and reduce the difficulty of producing the D-pillar structure 1.

[0057] In some embodiments, the bending surface 112 also includes a third bending surface 1123, which is connected to the first bending surface 1121 and the second bending surface 1122, the first bending surface 1121 is inclined to the first contact surface 111, the third bending surface 1123 is inclined to the first bending surface 1121, the second bending surface 1122 is inclined to the third bending surface 1123, and the second contact surface 113 is inclined to the second bending surface 1122.

[0058] It should be noted that, see Figure 3 , Figure 4 and Figure 5 . Figure 3 A structural schematic diagram of a D-pillar structure in an embodiment of the present application is shown. Figure 4 Shows Figure 3 Top view of the . Figure 5 Shows Figure 2 Since the bending surface 112 also includes a third bending surface 1123, which is connected to the first bending surface 1121 and the second bending surface 1122, the first bending surface 1121 is inclined to the first contact surface 111, the third bending surface 1123 is inclined to the first bending surface 1121, the second bending surface 1122 is inclined to the third bending surface 1123, and the second contact surface 113 is inclined to the second bending surface 1122, that is, the surface connection line of the first contact surface 111, the first bending surface 1121, the third bending surface 1123, the second bending surface 1122 and the second contact surface 113 is set to be a "J-shape". For the convenience of description, the structure of the above-mentioned D-pillar structure 1 is described below in terms of the "J-shape".

[0059] Specifically, since the surface connection lines of the first contact surface 111, the first bending surface 1121, the third bending surface 1123, the second bending surface 1122 and the second contact surface 113 are arranged in a "J" shape, after the first surface, the first bending surface 1121, the third bending surface 1123, the second bending surface 1122 and the second contact surface 113 are connected to the wheel cover 22, the D-pillar structure 1 is subjected to the forces at the corners of the "J" shape. Since the directions of the forces at the corners of the "J" shape are different, and the forces at the corners of the "J" shape are in relative directions, the connection between the D-pillar structure 1 and the wheel cover 22 can be made tighter, and the rigidity and strength of the D-pillar structure 1 can be improved. Accordingly, by limiting the forces in different directions at the corners of the "J" shape, on the basis that the D-pillar structure 1 meets the rigidity and strength requirements, it is not necessary to add additional parts between the D-pillar structure 1 and the wheel cover 22, and the weight of the vehicle 2 can be reduced.

[0060] In some embodiments, the angle between the first bending surface 1121 and the first contact surface 111 is greater than 90°, and the angle between the second bending surface 1122 and the second contact surface 113 is greater than 90°. Specifically, during the connection between the D-pillar structure 1 and the wheel cover 22, since the angle between the first bending surface 1121 and the first contact surface 111 is greater than 90°, and the angle between the second bending surface 1122 and the second contact surface 113 is greater than 90°, for the convenience of explanation, that is, along the projection direction of the depression of the open cavity 114, the projection of the bending surface 112 is located between the projection of the first contact surface 111 and the projection of the second contact surface 113, the D-pillar structure 1 can be buckled onto the wheel cover 22, which facilitates the connection and installation between the D-pillar structure 1 and the wheel cover 22. At the same time, since the projection of the bending surface 112 is located between the projection of the first contact surface 111 and the second contact surface 113, the size of the bending surface 112 can be reduced. On the one hand, the manufacturing cost required for the bending surface 112 can be reduced, thereby reducing the production cost of the D-pillar structure 1; on the other hand, the space occupied by the bending surface 112 can be reduced, thereby improving the overall space utilization of the D-pillar structure 1.

[0061] In some embodiments, the bending surface 112 includes a first bending surface 1121 and a second bending surface 1122. The first contact surface 111, the first bending surface 1121, the second bending surface 1122, and the second contact surface 113 are connected in sequence, and the first bending surface 1121 and the second bending surface 1122 are respectively arranged on both sides of the first contact surface 111. Specifically, since the first bending surface 1121 and the second bending surface 1122 are respectively arranged on both sides of the first contact surface 111, at this time, there are forces in completely opposite directions between the first bending surface 1121 and the wheel cover 22 and between the second bending surface 1122 and the wheel cover 22, thereby maximizing the connection tightness between the D-pillar structure 1 and the wheel cover 22, thereby enhancing the stiffness and strength of the D-pillar structure 1, and enabling the D-pillar structure 1 to meet higher stiffness and strength requirements.

[0062] In some embodiments, there are multiple matching parts 12, and the multiple matching parts 12 are arranged at intervals on the column 11. Specifically, since the multiple matching parts 12 are arranged at intervals on the column 11, the D-pillar structure 1 and the wheel cover 22 can be closely connected at different positions, and the local force between the D-pillar structure 1 and the wheel cover 22 can be dispersed through the connection between the multiple matching parts 12 and the wheel cover 22, thereby avoiding the excessive concentration of force between the D-pillar structure 1 and the wheel cover 22 in a local area, which causes the D-pillar structure 1 and the wheel cover 22 to separate or even break in a local area, thereby reducing the local force between the D-pillar structure 1 and the wheel cover 22, improving the service life and safety of the D-pillar structure 1, and ultimately improving the safety performance of the vehicle 2.

[0063] Optionally, the openings of the open cavities 114 of at least two mating parts 12 are opposite. Specifically, since the openings of the open cavities 114 of at least two mating parts 12 are opposite, there can be forces in completely opposite directions between the at least two mating parts 12 and the wheel cover 22, thereby improving the tightness of the connection between the D-pillar structure 1 and the wheel cover 22 to the greatest extent, thereby enhancing the rigidity and strength of the D-pillar structure 1, and enabling the D-pillar structure 1 to meet higher rigidity and strength requirements.

[0064] In some embodiments, the D-pillar structure 1 further includes a recessed portion 13. Figure 4 and Figure 6 . Figure 4 Shows Figure 3 Top view of the . Figure 6 Shows Figure 4 The recessed portion 13 is provided on the column 11 , and includes a first inner wall 131 , a second inner wall 132 and a third inner wall 133 , wherein the second inner wall 132 is connected to the first inner wall 131 and the third inner wall 133 , the second inner wall 132 is inclined to the first inner wall 131 , and the third inner wall 133 is inclined to the second inner wall 132 .

[0065] It should be noted that, during the manufacturing process of the D-pillar structure 1, it is necessary to pull the mold up and down to separate the punch and the die, thereby separating the D-pillar structure 1 from the punch and the die. However, the vertical depth of the D-pillar structure 1 is relatively deep. Even at a small draft angle (within 3°), the material thickness of the D-pillar structure 1 at the root position is still relatively thick, which generates additional weight during the drafting process, making it difficult to separate the D-pillar structure 1 from the punch and the die.

[0066] Specifically, since the D-pillar structure 1 also includes a recessed portion 13, the recessed portion 13 includes a first inner wall 131, a second inner wall 132 and a third inner wall 133, the second inner wall 132 is connected to the first inner wall 131 and the third inner wall 133, the second inner wall 132 is inclined to the first inner wall 131, and the third inner wall 133 is inclined to the second inner wall 132. Through the design of the recessed portion 13, the thickness of the D-pillar structure 1 is reduced. On the one hand, it is convenient to separate the D-pillar structure 1 from the punch and the die during the production process; on the other hand, the thickness of the D-pillar structure 1 is reduced, thereby reducing the weight of the D-pillar structure 1, and then reducing the weight of the vehicle 2, which is beneficial to the lightweight design of the vehicle 2.

[0067] In some embodiments, the D-pillar structure 1 further includes a ejection assembly 14. Figure 3 and Figure 7 . Figure 3 A structural schematic diagram of a D-pillar structure in an embodiment of the present application is shown. Figure 7 Shows Figure 3The partial enlarged schematic diagram of the A in the middle. The ejector assembly 14 includes an ejector member 141 and a support member 142 . The support member 142 is disposed between two surfaces of the column 11 that are inclined to each other. The ejector member 141 is connected to the support member 142 .

[0068] It should be noted that during the manufacturing process of the D-pillar structure 1, the D-pillar structure 1 needs to be ejected from the mold to complete the manufacturing of the D-pillar structure 1. Specifically, since the ejection assembly 14 includes an ejection member 141 and a support member 142, the support member 142 is disposed between two surfaces inclined to each other on the column 11, and the ejection member 141 is connected to the support member 142, on the one hand, the D-pillar structure 1 can be ejected from the mold by the cooperation of the ejection member 141 and the ejection mechanism in the mold, so as to facilitate the removal of the D-pillar structure 1. At the same time, through the structure of the ejection member 141, it is possible to prevent the ejection mechanism from directly acting on the main structure of the D-pillar structure 1 during the ejection of the D-pillar structure 1, thereby damaging the main structure of the D-pillar structure 1; on the other hand, the main structure of the D-pillar structure 1 can be supported by the support member 142 inclined between the two surfaces, thereby avoiding excessive force during ejection, and when the force acts on only one surface of the D-pillar structure 1, damaging the surface, thereby ensuring the smooth manufacturing of the D-pillar structure 1.

[0069] In some embodiments, the D-pillar structure 1 is an integrally formed structure. Specifically, since the D-pillar structure 1 is an integrally formed structure, on the one hand, no additional parts are required for connection and fixing inside the D-pillar structure 1, thereby reducing the weight of the D-pillar structure 1, and ultimately reducing the weight of the vehicle 2, which is conducive to the lightweight design of the vehicle 2; on the other hand, it is convenient to manufacture the D-pillar structure 1, and only the D-pillar structure 1 needs to be manufactured in one piece, and there is no need to split the D-pillar structure 1 into multiple parts and then connect and assemble them, which reduces the difficulty of processing and manufacturing for the staff, thereby improving the production efficiency of the D-pillar structure 1.

[0070] The vehicle 2 provided in one embodiment of the present application includes a vehicle body 21, a wheel housing 22 and a D-pillar structure 1, wherein the D-pillar structure 1 is connected to the vehicle body 21 and the wheel housing 22. Specifically, the D-pillar structure 1 is an important force-bearing component in the vehicle 2, which needs to bear the impact force of the vehicle 2. The D-pillar structure 1 is located at the rear of the vehicle 2 and is connected between the vehicle body 21 and the wheel housing 22. In the process of connecting the D-pillar structure 1 with the wheel housing 22, the first contact surface 111, the bending surface 112 and the second contact surface 113 are contact surfaces with the wheel housing 22 in different directions and angles. When the D-pillar structure 1 is subjected to forces in different directions, it can ensure that the D-pillar structure 1 and the wheel housing 22 are tightly connected, and there is no need to set additional parts between the D-pillar structure 1 and the wheel housing 22, thereby reducing the weight inside the D-pillar structure 1, thereby reducing the weight of the vehicle 2, which is conducive to the lightweight manufacturing of the vehicle 2.

[0071] The technical features of the above embodiments may be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0072] The above embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the patent application.
