Description

Technical Field

[0001] The present application relates to the field of vehicle technology, and in particular to a bracket assembly of a trunk door stay and a vehicle. Background Art

[0002] In modern car designs, the opening and closing of the trunk door (also known as the tailgate or luggage compartment door) usually relies on a strut (also known as a gas spring or hydraulic rod) to provide support and cushioning.

[0003] The strut is usually installed on the structural pillar (C-pillar) between the rear window and the trunk door of the car. The main function of the strut is to help the driver and passengers open and close the trunk door easily, while ensuring that the trunk door remains stable in the open state.

[0004] The support rod of the prior art is installed on the C-pillar via the Z direction (vertical direction) or the Y direction (horizontal side). When the trunk door is in the open state, the connection structure between the support rod and the C-pillar is subjected to a large shear force, making the connection position between the support rod and the C-pillar and the surrounding sheet metal structure easily damaged. Utility Model Content

[0005] In view of this, an embodiment of the present application provides a bracket assembly for a trunk door strut and a vehicle. By setting a support component, the ball head bracket connected to the trunk door strut is respectively connected to the first side surface in the Y direction and the second side surface in the Z direction of the C-pillar assembly, thereby optimizing the force conduction path between the ball head bracket and the C-pillar assembly, improving the connection strength between the ball head bracket and the C-pillar assembly, extending the service life of the ball head bracket and the C-pillar assembly, and thus improving user satisfaction.

[0006] In order to achieve the above-mentioned purpose, the technical solution of the embodiment of the present application is implemented as follows:

[0007] On the one hand, an embodiment of the present application provides a bracket assembly for a trunk door strut, for a vehicle, comprising: a C-pillar assembly, comprising a first side surface along the Y direction of the vehicle and a second side surface along the Z direction of the vehicle; a ball head bracket, comprising: a fixing plate and a ball head rod, one end of the ball head rod being connected to the fixing plate, and the other end being connected to the trunk door strut; a support assembly, the support assembly being fixedly connected to the first side surface and the second side surface of the C-pillar assembly respectively, and the fixing plate being fixedly arranged on the support assembly.

[0008] In the bracket assembly of the present invention, the fixing plate of the ball head bracket is fixedly connected to the first side surface and the second side surface of the C-pillar assembly through the support component. When the trunk door of the vehicle is opened, the trunk door support rod applies a shear force to the ball head rod. At this time, the force received by the ball head rod is evenly dispersed to the first side surface and the second side surface along the fixing plate through the support component. The connection strength between the ball head bracket and the C-pillar assembly is high, and the connection between the ball head bracket and the C-pillar assembly is not easy to loosen, thereby extending the service life of the bracket assembly and improving user satisfaction.

[0009] In one possible implementation, the support assembly includes: a first mounting plate, including a first mounting portion and a second mounting portion, the first mounting portion is connected to the first side surface, the second mounting portion is connected to the second side surface, and the ball head bracket is fixedly disposed on the first mounting portion.

[0010] In this way, the ball head bracket can disperse the force toward the first side and the second side when the trunk door is opened, reducing the concentration of force and helping to avoid deformation or even damage of the first mounting plate.

[0011] In a possible implementation, the support assembly further includes: a first reinforcing plate, the first mounting portion is connected to the first side surface via the first reinforcing plate, and an area of ​​the first reinforcing plate is larger than an area of ​​the first mounting portion.

[0012] In this way, the effective area of ​​the force transmitted from the ball head bracket to the first mounting plate is expanded, thereby enhancing the connection strength between the first mounting portion and the first side surface and improving the durability of the connection structure between the ball head bracket and the C-pillar assembly.

[0013] In a possible implementation, the first reinforcement plate includes: a first reinforcement connection area fixedly connected to the first mounting portion; and a second reinforcement connection area fixedly connected to the first side surface.

[0014] In this way, when the ball head bracket is subjected to force, the external force is transmitted to the first side surface through the first reinforced connection area and the second reinforced connection area, which is beneficial to improving the dispersion effect of the first reinforcement plate on the external force, thereby improving the durability of the first reinforcement plate.

[0015] In a possible implementation manner, the first reinforced connection area is spot-welded to the first mounting portion.

[0016] In this way, the connection and installation operation between the first reinforcing plate and the first mounting plate is convenient, and the connection strength between the first reinforced connection area and the first mounting portion is also guaranteed by spot welding. At the same time, the spot welding connection can also effectively disperse stress and reduce fatigue damage at the connection position between the first reinforcing plate and the first mounting portion.

[0017] In one possible implementation, a plurality of first connection holes are distributed in the second reinforced connection area, a plurality of second connection holes corresponding to the first connection holes are provided on the first side surface, and the second reinforced connection area and the first side surface are connected by fasteners passing through the first connection holes and the second connection holes in sequence.

[0018] In this way, a multi-point fixed structure is formed, which is conducive to enhancing the connection strength and stability between the second reinforced connection area and the first side surface, and improving the stability and durability of the support assembly during use.

[0019] In a possible implementation, the support assembly further includes:

[0020] A second reinforcing plate, wherein the second mounting portion is connected to the second side surface via the second reinforcing plate, and an area of ​​the second reinforcing plate is larger than an area of ​​the second mounting portion.

[0021] In this way, the force acting on the ball head bracket can be dispersed and transmitted to the second reinforcement plate with a larger area through the second mounting part, thereby increasing the area where the force is dispersed and improving the structural strength of the connection between the ball head bracket and the second mounting part.

[0022] In a possible implementation, the second reinforcing plate is welded to the second mounting portion and the second side surface respectively.

[0023] In this way, the welding connection can provide a stable connection method, preventing the connection between the second reinforcing plate and the second mounting portion and the second side from loosening or relative movement, thereby improving the stability and reliability of the bracket assembly.

[0024] In a possible implementation, the second reinforcing plate is connected to the second mounting portion by plug welding.

[0025] The plug welding connection has a high shear resistance and can provide a large local connection strength for the connection between the second reinforcing plate and the second mounting portion, thereby further improving the stability and reliability of the bracket assembly.

[0026] On the other hand, an embodiment of the present application further provides a vehicle, comprising:

[0027] A bracket assembly for a trunk door support rod according to any one of the above possible implementations.

[0028] The vehicle of the present invention uses the above-mentioned trunk door strut bracket assembly. Therefore, when the trunk door of the vehicle is opened, the trunk door strut applies a shear force to the ball head rod. At this time, the force acting on the ball head rod is evenly dispersed to the first side and the second side along the fixed plate through the support assembly, which has a good force dispersion effect. The connection strength between the ball head bracket and the C-pillar assembly is high, and the connection between the ball head bracket and the C-pillar assembly is not easy to loosen, thereby extending the service life of the bracket assembly and improving user satisfaction.

[0044] Reference below Figure 1 and Figure 2 , describing the bracket assembly 100 of the trunk door support rod provided in the first aspect of the embodiment of the present application, which can be used in a vehicle. The bracket assembly 100 may include: a C-pillar assembly 110, a ball head bracket 120 and a support component 130.

[0045] The C-pillar assembly 110 may include, but is not limited to, a structural pillar between the vehicle's rear window and trunk door. A trunk door brace is provided on the C-pillar assembly 110 to provide support and cushioning for the opening and closing of the vehicle's trunk door. At the location corresponding to the trunk door, the C-pillar assembly 110 may have a first side surface and a second side surface. The first side surface may face the Y direction, i.e., the left-right direction of the vehicle body, and the second side surface may face the Z direction, i.e., the vertical direction along the vehicle body and perpendicular to the ground.

[0046] The ball head bracket 120 may include a fixing plate 121 and a ball head rod 122, one end of the ball head rod 122 is connected to the fixing plate 121, and the other end (the end with the ball head) is connected to the trunk door strut, providing an installation structural basis for the trunk door strut. The ball head rod 122 and the trunk door strut are connected through a ball head pair, so that the connection between the trunk door strut and the ball head rod 122 is stable.

[0047] Support assembly 130 is fixedly connected to the first and second sides of C-pillar assembly 110, respectively. Fixing plate 121 is fixedly mounted on support assembly 130. For example, fixing plate 121 may be integrally formed with at least a portion of support assembly 130, or welded to support assembly 130. Alternatively, fixing plate 121 may be fixedly connected to support assembly 130 via bolts or screws. This allows the force exerted by the trunk door brace on ball bracket 120 to be evenly distributed across the first and second sides during trunk door opening and closing.

[0048] The bracket assembly 100 of the trunk door strut of the present invention, the fixing plate 121 of the ball head bracket 120 is fixedly connected to the first side and the second side of the C-pillar assembly 110 respectively through the support assembly 130. When the trunk door of the vehicle is opened, the trunk door strut applies a force to the ball head rod 122. At this time, the force applied to the ball head rod 122 is evenly dispersed to the first side and the second side along the fixing plate 121 through the support assembly 130. The effective area is large and the force dispersion effect is good, which enhances the structural stability of the bracket assembly 100. The connection between the ball head bracket 120 and the C-pillar assembly 110 is not easy to loosen, which extends the service life of the bracket assembly 100 and improves user satisfaction.

[0049] In some embodiments, support assembly 130 may include a first mounting plate 131, which may include a first mounting portion 1311 and a second mounting portion 1312. First mounting portion 1311 is connected to the first side surface by welding, screwing, or riveting. Second mounting portion 1312 is connected to the second side surface by a similar connection method to that between first mounting portion 1311 and the first side surface. Thus, first mounting plate 131 may be formed into an L-shaped plate.

[0050] Ball bracket 120 is fixedly mounted on first mounting portion 1311. Ball rod 122 can extend in the Y direction, facilitating the expansion and contraction of the trunk door stay connected to ball rod 122 during trunk opening and closing. During this process, ball bracket 120 disperses the applied force toward the first and second sides, reducing the concentration of force. This helps prevent deformation or even damage to first mounting plate 131, thereby improving the structural stability of bracket assembly 100.

[0051] Optionally, the fixing plate 121 of the ball stud bracket 120 may be integrally formed with the first mounting plate 131, or the fixing plate 121 and the first mounting plate 131 may be welded to each other to facilitate a fixed connection between the ball stud bracket 120 and the first mounting plate 131. Alternatively, the fixing plate 121 and the first mounting plate 131 may be detachably connected by a connector such as a screw to facilitate maintenance and replacement of the ball stud bracket 120.

[0052] According to some embodiments of the present invention, the support assembly 130 may further include a first reinforcement plate 132, through which the first mounting portion 1311 is connected to the first side surface. The area of ​​the first reinforcement plate 132 is larger than that of the first mounting portion 1311. This increases the area over which the force transmitted from the ball stud bracket 120 to the first mounting plate 131 acts, thereby enhancing the connection strength between the first mounting portion 1311 and the first side surface and improving the durability of the connection structure between the ball stud bracket 120 and the C-pillar assembly 110.

[0053] According to some embodiments of the present invention, the first reinforcement plate 132 may include a first reinforcement connection area 1321 and a second reinforcement connection area 1322. The first reinforcement connection area 1321 is fixedly connected to the first mounting portion 1311, and the connection method may be welding, or the first reinforcement connection area 1321 and the first mounting portion 1311 may also be fixedly connected by connecting parts such as screws and pins; the second reinforcement connection area 1322 is fixedly connected to the first side surface, and the connection method of the second reinforcement connection area 1322 and the first side surface may refer to the connection method of the first reinforcement connection area 1321 and the first mounting portion 1311.

[0054] In this way, when the ball head bracket 120 is subjected to force, the external force is transmitted to the first side surface through the first reinforced connection area 1321 and the second reinforced connection area 1322, and the dispersion area is increased, which is beneficial to improving the dispersion effect of the first reinforcing plate 132 on the external force, thereby improving the durability of the first reinforcing plate 132.

[0055] It is understood that, to match the structure of the vehicle's trunk door, the first side surface may have a partial protrusion or groove, and the second reinforced connection area 1322 may have a mating structure that matches the structure on the first side surface, so that the first reinforcement plate 132 is tightly fitted to the first side surface of the C-pillar assembly 110, thereby facilitating the even distribution of the forces acting on the bracket assembly 100 to the first side surface, thereby improving the structural stability of the bracket assembly 100. The structure on the first side surface and the mating structure of the second reinforced connection area 1322 can be designed by the designer according to actual needs, and this application does not impose any restrictions thereto.

[0056] Furthermore, the first reinforced connection area 1321 can be spot-welded to the first mounting portion 1311. This spot welding ensures sufficient connection strength between the first reinforced connection area 1321 and the first mounting portion 1311, and facilitates installation and connection of the first reinforcing plate 132 to the first mounting plate 131. Furthermore, the spot welding between the first reinforced connection area 1321 and the first mounting portion 1311 creates a multi-point connection structure that effectively disperses stress, thereby reducing fatigue damage at the connection between the first reinforcing plate 132 and the first mounting portion 1311.

[0057] According to some embodiments of the present invention, the first side surface is provided with a plurality of second connection holes, and the second reinforced connection area 1322 is provided with a plurality of first connection holes, with the first connection holes corresponding to the second connection holes. The bracket assembly 100 may also include a fastener 133, which passes through the first connection holes and the second connection holes in sequence to securely connect the second reinforced connection area 1322 to the first side surface.

[0058] The second reinforced connection area 1322 and the first side are fixedly connected by fasteners 133, and a plurality of connection structures between the second reinforced connection area 1322 and the first side are distributed, thus forming a multi-point connection structure, which is beneficial to enhancing the connection strength and stability between the second reinforced connection area 1322 and the first side, and improving the stability and durability of the support assembly 130 during use.

[0059] Optionally, the fasteners 133 may include but are not limited to screws, bolts, nuts, or pins, which helps save material costs and facilitates the fixed connection operation between the first reinforcing plate 132 and the first side.

[0060] According to some embodiments of the present invention, the support assembly 130 may further include a second reinforcing plate 134, through which the second mounting portion 1312 is connected to the second side surface, and the area of ​​the second reinforcing plate 134 is larger than that of the second mounting portion 1312. In this way, the force acting on the ball bracket 120 can be dispersed and transmitted to the larger second reinforcing plate 134 through the second mounting portion 1312, thereby increasing the area over which the force is dispersed and improving the structural strength of the connection between the ball bracket 120 and the second mounting portion 1312.

[0061] According to some embodiments of the present invention, the second reinforcing plate 134 is welded to the second mounting portion 1312 and the second side surface respectively, so that the force acting on the ball head bracket 120 can be transmitted to the second side surface through the second mounting portion 1312 and the second reinforcing plate 134 .

[0062] In this way, the welding connection can provide a stable connection method, preventing the connection between the second reinforcing plate 134 and the second mounting portion 1312 and the second side from loosening or relative movement, thereby improving the stability and reliability of the bracket assembly 100.

[0063] Furthermore, the second reinforcing plate 134 and the second mounting portion 1312 are connected by plug welding, that is, a through hole is processed on the second mounting portion 1312 to align the second reinforcing plate 134 with the second mounting portion 1312, and the welding equipment welds and fixes the second reinforcing plate 134 and the second mounting portion 1312 through the through hole. The plug welding connection has high shear resistance, providing a greater local connection strength for the connection between the second reinforcing plate 134 and the second mounting portion 1312, thereby further improving the stability and reliability of the bracket assembly 100.

[0064] It is understood that, to match the structure of the vehicle's trunk door, the second side surface may have a partial protrusion or groove, and the second reinforcement plate 134 may have a mating structure that matches the structure on the second side surface, so that the second reinforcement plate 134 is tightly fitted and installed with the second side surface of the C-pillar assembly 110, thereby facilitating the uniform distribution of the forces acting on the bracket assembly 100 to the second side surface, thereby improving the structural strength of the bracket assembly 100. The structure on the second side surface and the mating structure of the second reinforcement plate 134 can be designed by the designer according to actual needs, and this application does not impose any restrictions thereto.

[0065] The assembly process of the bracket assembly 100 of the present invention can be:

[0066] The first mounting portion 1311 of the first mounting plate 131 is spot-welded to the first reinforced connection area 1321 of the first reinforcement plate 132, forming an integral structure with the first mounting plate 131. The ball head bracket 120 is fixedly mounted to the first mounting portion 1311. The integral structure formed by the first reinforcement plate 132 and the first mounting plate 131 is mounted to the C-pillar assembly 110 with the first connection hole aligned with the second connection hole. The integral structure formed by the first reinforcement plate 132 and the first mounting plate 131 is mounted to the first side surface by fasteners 133 passing through the first and second connection holes. Simultaneously, the second mounting portion 1312 and the second reinforcement plate 134 are stacked and mounted to the second side surface along the Z direction, and the second reinforcement plate 134 is connected to the second mounting portion 1312 by plug welding.

[0067] In a second aspect, an embodiment of the present application further provides a vehicle, which may include the above-mentioned trunk door stay bracket assembly 100.

[0068] The vehicle of the present invention uses the above-mentioned trunk door strut bracket assembly 100. When the trunk door of the vehicle is opened, the trunk door strut applies a shear force to the ball head rod 122. At this time, the force acting on the ball head rod 122 is evenly dispersed to the first side and the second side along the fixing plate 121 through the support assembly 130, which has a good force dispersion effect. The connection strength between the ball head bracket 120 and the C-pillar assembly 110 is high, and the connection between the ball head bracket 120 and the C-pillar assembly 110 is not easy to loosen, thereby extending the service life of the bracket assembly 100 and improving user satisfaction.
