Description

Technical Field

[0001] This invention relates to the field of vehicle technology, and in particular to a D-pillar connector assembly for a vehicle and the vehicle thereof. Background Technology

[0002] Since the birth of the automobile, automakers have continuously improved the vehicle body structure to achieve a comfortable and stable ride. Among these improvements, the torsional stiffness of the body-in-white is an important indicator for evaluating the overall performance of a vehicle.

[0003] In related technologies, during the early development of the vehicle body structure, it is necessary to ensure that the body-in-white has sufficient torsional stiffness to meet the target value requirements. This avoids repeated structural modifications due to insufficient torsional stiffness of the body-in-white, which would increase the operating costs of the vehicle. Typically, the connectors on the D-pillar of a car are T-joints, and the T-joint structure has always been a challenge in stamping and assembly welding. Since the three joints of the T-joint structure are all mating surfaces, high machining precision is required.

[0004] However, the poor stiffness and strength of the joint on the D-pillar in the existing technology leads to poor overall strength and stiffness of the vehicle body. Summary of the Invention

[0005] The present invention aims to at least solve one of the technical problems existing in the prior art. Therefore, one object of the present invention is to provide a D-pillar connector assembly for vehicles that is relatively easy to manufacture and has a simple production process.

[0006] Another object of the present invention is to provide a vehicle.

[0007] According to the present invention, a D-pillar connector assembly for a vehicle is provided, the D-pillar connector assembly being adapted for connection to a vehicle body, the D-pillar connector assembly comprising:

[0008] Connector outer plate;

[0009] The inner plate of the joint and the inner plate of the side beam are interconnected. The inner plate of the joint and the inner plate of the side beam are located on the same side of the outer plate of the joint and are respectively connected to the outer plate of the joint. The outer plate of the joint, the inner plate of the joint and the inner plate of the side beam together form an assembly space.

[0010] A partition component is disposed within the assembly space to divide the assembly space into a first cavity structure and a second cavity structure.

[0011] The D-pillar connector assembly proposed according to the present invention significantly reduces the production steps and processing difficulty of the D-pillar connector assembly by fixing the inner plate of the connector to the inner plate of the side beam and placing them together on the same side of the outer plate of the connector. It also significantly improves the production precision of the D-pillar connector assembly. By fixing the inner plate of the connector and the inner plate of the side beam to the outer plate of the connector, the strength and rigidity of the D-pillar connector assembly are effectively improved, thereby enhancing the overall strength and rigidity of the vehicle body. This, in turn, improves the torsional mode and torsional stiffness value of the vehicle body, enhancing the overall durability, NVH performance, and handling stability of the vehicle body. By providing a partition component, the assembly space is divided into two relatively independent first cavity structure and second cavity structure, further enhancing the strength and rigidity of the D-pillar connector assembly itself, thus further improving the overall vehicle performance.

[0016] The second reinforcing member is disposed at the other end of the inner panel of the connector near the bottom of the vehicle body, and the second reinforcing member is connected to the outer panel of the connector and the inner panel of the connector respectively.

[0017] The first reinforcing member, the second reinforcing member, the outer plate of the connector, and the inner plate of the connector together form the first cavity structure.

[0018] In some examples of the present invention, the D-pillar connector assembly further includes:

[0019] A connecting outer plate is provided, one end of which is connected to the connector outer plate.

[0020] A connecting inner plate is provided, one end of which is connected to the connector inner plate, and the connecting inner plate is also connected to the connecting outer plate.

[0021] The second partition is disposed between the connecting outer plate and the connecting inner plate, and is connected to both the connecting outer plate and the connecting inner plate. The second partition, the second reinforcing member, the connecting outer plate, and the connecting inner plate together form a third cavity structure.

[0022] In some examples of the present invention, the second reinforcement is constructed as a box-shaped structure.

[0057] The following is for reference. Figures 1-8 A D-pillar connector assembly 10 for a vehicle according to an embodiment of the present invention is described. The D-pillar connector assembly 10 is adapted to connect to a vehicle body (not shown in the figure). The D-pillar connector assembly 10 includes: an outer connector plate 110; an inner connector plate 120 and a side beam inner plate 130 connected to each other, the inner connector plate 120 and the side beam inner plate 130 being disposed on the same side of the outer connector plate 110 and respectively connected to the outer connector plate 110; the outer connector plate 110, the inner connector plate 120, and the side beam inner plate 130 together form an assembly space. A partition assembly is disposed within the assembly space to divide the assembly space into a first cavity structure (not shown in the figure) and a second cavity structure (not shown in the figure).

[0058] Specifically, the D-pillar connector assembly 10 can be installed on the upper two sides of the rear end of the vehicle body. The D-pillar connector assembly 10 can be fixedly connected to the upper end of the D-pillar (not shown in the figure), the opposite ends of the rear crossbeam (not shown in the figure), and the rear end of the side beam (not shown in the figure), respectively. The specific connection method can be welding, riveting, or threaded connection, etc. The present invention does not specifically limit this. With this configuration, the D-pillar, rear crossbeam, and side beam of the vehicle body can be fixedly connected together by the D-pillar connector assembly 10, which can effectively improve the overall strength and rigidity of the vehicle body.

[0059] Please continue reading Figures 1-4As shown, the outer joint plate 110 and the inner joint plate 120 can be integrally cast, and both can be constructed as plate structures. The outer joint plate 110 and the inner joint plate 120 can be arranged opposite each other and fixedly connected by welding, riveting, or threaded connections. The outer joint plate 110 can be located on the outer side of the vehicle body, and the inner joint plate 120 can be located on the inner side of the vehicle body. The outer joint plate 110 can be constructed as a T-joint, and can be used to fixably connect to the D-pillar, the rear crossbeam, and the side beam, respectively. The upper end of the inner plate 120 near the top of the vehicle body can be used for fixed connection with the end of the rear crossbeam, and the lower end of the inner plate 120 near the bottom of the vehicle body can be used for fixed connection with the D-pillar. The specific connection method can be welding, riveting or threaded connection, etc. This setting can effectively improve the strength and rigidity of the D-pillar joint assembly 10, thereby improving the overall strength and rigidity of the vehicle body, and further improving the torsional mode and torsional stiffness value of the vehicle body, enhancing the overall durability, NVH performance and handling stability of the vehicle body.

[0060] Please continue reading Figures 1-4 As shown, the inner panel 130 of the side beam can also be cast in one piece, or it can be constructed as a plate structure. One end of the inner panel 130 can be fixedly connected to the outer panel 110 and the inner panel 120 of the joint, and the other end of the inner panel 130 can be fixedly connected to the side beam. The specific connection methods can be welding, riveting, or threaded connection, etc. The inner panel 130 of the side beam and the inner panel 120 of the joint can both be located on the same side of the outer panel 110 near the interior of the vehicle body. This arrangement can effectively improve the strength and rigidity of the D-pillar joint assembly 10, thereby improving the overall strength and rigidity of the vehicle body, and further improving the torsional mode and torsional stiffness value of the vehicle body, enhancing the overall durability, NVH performance, and handling stability of the vehicle body.

[0061] It should be noted that by fixing the inner plate 120 of the joint to the inner plate 130 of the side beam and setting them together on the same side of the outer plate 110 of the joint, the production process of the D-pillar joint assembly 10 can be greatly reduced, the processing difficulty of the D-pillar joint assembly 10 can be significantly reduced, and the production precision of the D-pillar joint assembly 10 can be significantly improved.

[0062] The outer plate 110, inner plate 120, and inner side beam plate 130 together form an assembly space. The partition component is located in the assembly space, which can divide the assembly space into a first cavity structure and a second cavity structure. With this configuration, the assembly space can be divided into two relatively independent first cavity structures and second cavity structures by the partition component, which can further improve the strength and rigidity of the D-pillar joint assembly 10 itself, so as to further improve the overall vehicle performance.

[0063] According to the embodiments of the present invention, the D-pillar joint assembly 10, by fixing the inner plate 120 of the joint and the inner plate 130 of the side beam together and placing them on the same side of the outer plate 110, can significantly reduce the production steps of the D-pillar joint assembly 10, significantly reduce the processing difficulty of the D-pillar joint assembly 10, and can also significantly improve the production precision of the D-pillar joint assembly 10. By fixing the inner plate 120 of the joint and the inner plate 130 of the side beam to the outer plate 110 of the joint respectively, the strength and rigidity of the D-pillar joint assembly 10 can be effectively improved, thereby improving the overall strength and rigidity of the vehicle body, and further improving the torsional mode and torsional stiffness value of the vehicle body, enhancing the overall durability, NVH performance and handling stability of the vehicle body. By setting the partition component, the cavity between the outer plate 110 of the joint and the inner plate 120 of the joint and the inner plate 130 of the side beam can be divided into two relatively independent first cavity structure and second cavity structure, which can further improve the strength and rigidity of the D-pillar joint assembly 10 itself, so as to further improve the overall vehicle performance.

[0064] Please continue reading Figures 1-7 As shown, according to an embodiment of the present invention, the D-pillar joint assembly 10 may further include a reinforcing structure disposed between the outer joint plate 110 and the inner joint plate 120. The reinforcing structure is adapted to form a first cavity structure (not shown in the figure) together with the outer joint plate 110 and the inner joint plate 120. The reinforcing structure may be constructed as a plate-like structure and may be fixedly disposed within the space enclosed by the outer joint plate 110 and the inner joint plate 120. The reinforcing structure may be fixedly connected to the outer joint plate 110 and the inner joint plate 120 respectively. The reinforcing structure may be disposed at opposite ends in the extending direction of the inner joint plate 120 and may form the first cavity structure together with the inner joint plate 120 and the outer joint plate 110. This arrangement allows for the arrangement of the first cavity structure, which is beneficial for improving the strength and rigidity of the D-pillar joint assembly 10 itself.

[0065] Please continue reading Figures 1-7 As shown, according to an embodiment of the present invention, the D-pillar joint assembly 10 may further include: a first partition 150, which is disposed between the outer plate 110 of the joint and the inner plate 130 of the side beam. The first partition 150 is adapted to form a second cavity structure together with the outer plate 110 of the joint and the inner plate 130 of the side beam. The first partition 150 may be constructed as a plate-like structure. The first partition 150 may be fixedly disposed within the space enclosed by the outer plate 110 of the joint and the inner plate 130 of the side beam, and the first partition 150 may be fixedly connected to both the outer plate 110 of the joint and the inner plate 130 of the side beam. The first partition 150, together with the outer plate 110 of the joint and the inner plate 130 of the side beam, forms the second cavity structure. This arrangement allows for the arrangement of the second cavity structure, which is beneficial for improving the strength and rigidity of the D-pillar joint assembly 10 itself.

[0066] By setting up a reinforcing structure and a first partition 150, the space between the outer plate 110 of the connector and the inner plate 120 of the connector and the inner plate 130 of the side beam can be divided into two relatively independent first cavity structures and second cavity structures. This can further improve the strength and rigidity of the D-pillar connector assembly 10 itself, so as to further improve the overall vehicle performance.

[0067] Please continue reading Figures 1-4 as well as Figure 8 As shown, according to an embodiment of the present invention, the D-pillar connector assembly 10 further includes: a connecting outer plate 160, one end of which is connected to the connector outer plate 110; a connecting inner plate 170, one end of which is connected to the connector inner plate 120, and the connecting inner plate 170 is connected to the connecting outer plate 160; and a second partition 180, which is disposed between the connecting outer plate 160 and the connecting inner plate 170, and is connected to both the connecting outer plate 160 and the connecting inner plate 170. The second partition 180, the reinforcing structure, the connecting outer plate 160, and the connecting inner plate 170 together form a third cavity structure.

[0068] Specifically, the connecting outer plate 160 can be cast in one piece, and can be constructed as a plate-like structure. One end of the connecting outer plate 160 can be fixedly connected to the end of the connector outer plate 110 near the bottom of the vehicle body, and the other end of the connecting outer plate 160 away from the connector outer plate 110 can be used for fixed connection to the D-pillar. Specific connection methods can include welding, riveting, or threaded connection, etc. This embodiment of the invention does not specifically limit the specific connection methods. This configuration allows the connector outer plate 110 to be fixedly connected to the D-pillar via the connecting outer plate 160.

[0069] Please continue reading Figures 1-4 As shown, the connecting inner plate 170 can also be cast in one piece, or it can be constructed as a plate-like structure. One end of the connecting inner plate 170 can be fixedly connected to the end of the connector inner plate 120 near the bottom of the vehicle body, and the other end of the connecting inner plate 170 away from the connector inner plate 120 can be used for fixed connection to the D-pillar. Specific connection methods can include welding, riveting, or threaded connection, etc. This embodiment of the invention does not specifically limit the method. This arrangement allows the connector inner plate 120 to be fixedly connected to the D-pillar via the connecting inner plate 170.

[0070] Please continue reading Figures 1-4 as well as Figure 8As shown, the opposite edges of the connecting outer panel 160 and the connecting inner panel 170 can be fixedly connected by welding, and a cavity structure can be constructed between the connecting inner panel 170 and the connecting outer panel 160. A second partition 180 can be disposed between the connecting outer panel 160 and the connecting inner panel 170, and the second partition 180 is fixedly connected to both the connecting inner panel 170 and the connecting outer panel 160. Specific connection methods can include welding, riveting, or threaded connection, etc. This embodiment of the invention does not specifically limit the method. With this configuration, the cavity between the connecting outer panel 160 and the connecting inner panel 170 can be divided into multiple cavity structures by the second partition 180. This effectively improves the strength and rigidity of the D-pillar joint assembly 10, thereby improving the overall strength and rigidity of the vehicle body, and further improving the vehicle body's torsional mode, torsional stiffness value, and enhancing the overall vehicle body's durability, NVH performance, and handling stability.

[0071] The second partition 180, the reinforcing structure, the connecting outer panel 160, and the connecting inner panel 170 together form the third cavity structure.

[0072] Specifically, the end of the connecting outer plate 160 near the joint outer plate 110 can be simultaneously fixedly connected to the reinforcing structure, and the end of the connecting inner plate 170 near the joint inner plate 120 can also be simultaneously fixedly connected to the reinforcing structure. The second partition 180 can be disposed in the space between the connecting outer plate 160 and the connecting inner plate 170, and the second partition 180 can be disposed on the side of the connecting outer plate 160 and / or the connecting inner plate 170 away from the reinforcing structure. The second partition 180 can also be fixedly connected to the connecting outer plate 160 and the connecting inner plate 170 respectively by welding or other means. This arrangement allows the second partition 180, the reinforcing structure, the connecting outer plate 160, and the connecting inner plate 170 to jointly form a third cavity structure, which can further improve the strength and rigidity of the D-pillar joint assembly 10 itself, thereby further improving the overall vehicle performance and meeting the performance requirements of the vehicle's NVH and structural durability properties.

[0073] Please continue reading Figures 1-6 As shown, according to an embodiment of the present invention, the reinforcing structure may include: a first reinforcing member 141, which is disposed at one end of the inner plate 120 near the top of the vehicle body, and the first reinforcing member 141 is connected to the outer plate 110 and the inner plate 120 of the joint respectively.

[0074] Specifically, the first reinforcing member 141 can be an inner reinforcing plate of the rear crossbeam tailgate. The first reinforcing member 141 can be integrally cast. The first reinforcing member 141 can be constructed as a box-shaped structure. The first reinforcing member 141 can include a first reinforcing body and a first connecting flange. The first connecting flange is connected to the first reinforcing body. The first reinforcing body defines a groove structure. The first connecting flange can be set around the first reinforcing body. The first connecting flange can be connected to the inner plate 120 of the connector. The first reinforcing body can be connected to the outer plate 110 of the connector. The first reinforcing member 141 can be fixedly connected to the end of the outer plate 110 of the connector near the rear crossbeam and the end of the inner plate 120 of the connector near the rear crossbeam, respectively. This configuration can effectively improve the strength and rigidity of the D-pillar connector assembly 10, thereby improving the overall strength and rigidity of the vehicle body.

[0075] Furthermore, the first reinforcing member 141 can also be used to fix it to the rear crossbeam of the vehicle body. With this arrangement, the first reinforcing member 141 and other surrounding components can form a box-shaped structure, which can improve the rigidity of the vehicle's tailgate (not shown in the figure) mounting point and meet the performance requirements of the vehicle's NVH and structural durability properties.

[0076] Please continue reading Figures 1-6 As shown, the reinforcing structure may further include: a second reinforcing member 142, which is disposed at the other end of the inner plate 120 near the bottom of the vehicle body, and the second reinforcing member 142 is connected to the outer plate 110 and the inner plate 120 of the joint respectively.

[0077] Specifically, the second reinforcing member 142 can be an inner reinforcing plate of the tailgate support rod. The second reinforcing member 142 can also be integrally cast, or it can be constructed as a box-shaped structure. The second reinforcing member 142 can be fixedly connected to the end of the connector outer plate 110 near the connecting outer plate 160 and the end of the connector inner plate 120 near the connecting inner plate 170, respectively. The second reinforcing member 142 can include a second reinforcing body and a second connecting flange. The second connecting flange is connected to the second reinforcing body, and the second reinforcing body defines a groove structure. There are multiple second connecting flanges, spaced apart from the edges of the second reinforcing body. The second connecting flanges can be connected to the connector inner plate 120, and the second reinforcing body can be connected to the connector outer plate 110. This configuration effectively improves the strength and rigidity of the D-pillar connector assembly 10, thereby improving the overall strength and rigidity of the vehicle body.

[0078] Please continue reading Figures 1-6 As shown, the first reinforcing member 141, the second reinforcing member 142, the outer plate of the connector 110, and the inner plate of the connector together form the first cavity structure.

[0079] Specifically, the first reinforcing member 141 and the second reinforcing member 142 can both be disposed within the cavity between the outer plate 110 and the inner plate 120 of the connector, and the first reinforcing member 141 and the second reinforcing member 142 can be fixedly connected to their respective ends along the extension direction of the inner plate 120 of the connector. For example, the first reinforcing member 141 and the second reinforcing member 142 can be fixedly connected to the outer plate 110 and the inner plate 120 of the connector respectively by welding or other methods. This arrangement allows the first reinforcing member 141 and the second reinforcing member 142 to form a first cavity structure within the cavity between the outer plate 110 and the inner plate 120 of the connector. This further enhances the strength and rigidity of the D-pillar connector assembly 10, thereby further improving the overall vehicle performance and meeting the performance requirements of the vehicle's NVH and structural durability properties.

[0080] Please continue reading Figures 1-6 As shown, according to a further embodiment of the present invention, the second reinforcing member 142, the connecting outer plate 160, the second partition 180, and the connecting inner plate 170 together form a third cavity structure.

[0081] Specifically, the end of the connecting outer plate 160 near the joint outer plate 110 can be simultaneously fixedly connected to the second reinforcing member 142, and the end of the connecting inner plate 170 near the joint inner plate 120 can also be simultaneously fixedly connected to the second reinforcing member 142. The second partition 180 can be disposed in the cavity between the connecting outer plate 160 and the connecting inner plate 170, and the second partition 180 can be disposed on the side of the connecting outer plate 160 and / or the connecting inner plate 170 away from the second reinforcing member 142. The second partition 180 can also be fixedly connected to the connecting outer plate 160 and the connecting inner plate 170 respectively by welding or other means. This arrangement allows the second reinforcing member 142 and the second partition 180 to form a third cavity structure around the cavity between the connecting outer plate 160 and the connecting inner plate 170. This can further improve the strength and rigidity of the D-pillar joint assembly 10 itself, thereby further improving the overall vehicle performance and meeting the performance requirements of the vehicle's NVH and structural durability properties.

[0082] Please continue reading Figure 6 As shown, in an optional embodiment of the present invention, the second reinforcing member 142 is constructed as a box-shaped structure. Specifically, the second reinforcing member 142 can be constructed as a box-shaped structure, which can improve the supporting reaction force of the tailgate strut of the vehicle and meet the performance requirements of the vehicle's NVH and structural durability properties.

[0085] Please continue reading Figures 1-3 As shown, in some possible implementations of the present invention, the D-pillar joint assembly 10 further includes a connecting bracket 192, one end of which is connected to the connecting outer plate 160 and / or the connecting inner plate 170, and the other end of which is adapted to be connected to the top of the vehicle's shock absorber tower.

[0086] Specifically, the connecting bracket 192 can also be cast integrally, or it can be constructed as a plate-like structure. One end of the connecting bracket 192 can be fixedly connected to the connecting outer plate 160 and / or the connecting inner plate 170, and the other end of the connecting bracket 192 away from the connecting outer plate 160 and / or the connecting inner plate 170 can be fixedly connected to the vehicle's shock absorber tower top (not shown in the figure). The specific connection method can be welding, riveting, or threaded connection, etc. The embodiments of the present invention do not specifically limit this. This arrangement allows the shock absorber tower top to be fixedly connected to the connecting outer plate 160 and / or the connecting inner plate 170 through the connecting bracket 192 to form a new ring structure. This can further enhance the strength and rigidity of the D-pillar joint assembly 10 to meet the vehicle's NVH properties, structural durability properties, and safety properties.
