[0001] This utility model relates to the field of vehicle manufacturing technology, and in particular to a door anti-collision beam assembly, a door assembly, and a vehicle. Background Technology

[0002] As living standards improve, people are paying increasing attention to their personal safety. When buying a car, they no longer only focus on the vehicle's appearance, performance, and comfort; safety performance, especially crash safety performance, has become a crucial consideration. Consumers actively seek information about a car's safety features and crash test ratings, tending to choose models with superior safety performance. The new versions of C-IASI 2023 and C-NCAP 2024 have raised the height and weight of the side impact barrier, while also specifying various indicators for vehicles in side collisions. This compels automakers to adopt effective measures to improve the impact resistance of car doors, making door anti-collision beams an important technical means to meet regulatory requirements. On the one hand, it is necessary to enhance vehicle safety performance to meet the new crash test standards; on the other hand, the impact of vehicle weight on energy consumption must also be considered. Utility Model Content

[0003] Therefore, this utility model embodiment provides a door anti-collision beam assembly that ensures the structural strength of the vehicle while avoiding an increase in the vehicle's weight.

[0004] To achieve the above objectives, the technical solution of this utility model embodiment is implemented as follows:

[0005] In a first aspect, this utility model provides a door anti-collision beam assembly, which is connected to a door. The door anti-collision beam assembly includes: an anti-collision beam body; a connecting bracket, on which a connecting groove is formed, at least a portion of the anti-collision beam body is disposed in the connecting groove and fixedly connected to the connecting groove, a first connecting portion is formed on the bottom wall of the connecting groove, and a second connecting portion is formed on the door. The first connecting portion is adapted to cooperate with the second connecting portion so that the connecting bracket is connected to the door.

[0006] According to the present invention, the door anti-collision beam assembly improves the connection stability between the connecting bracket and the door by cooperating with the first connecting part and the second connecting part, preventing the door anti-collision beam assembly from loosening or falling off. By nesting and fixing the connecting bracket and the anti-collision beam body, the overall rigidity of the door anti-collision beam assembly is improved, ensuring the structural strength of the vehicle while avoiding an increase in the vehicle's own weight.

[0007] In one possible implementation of this utility model, the car door includes an inner panel and an outer panel, the second connecting portion is formed on the inner panel, and the connecting bracket is connected to the inner panel through the cooperation of the first connecting portion and the second connecting portion.

[0008] In this way, fixing the connecting bracket to the inner panel can improve the overall connection strength and enhance the force transmission efficiency during a collision. Furthermore, the inner panel structure is relatively flat and stable, which facilitates positioning and connection, improves the consistency and precision of assembly, does not damage the integrity of the outer panel surface, and maintains the aesthetic appearance of the door.

[0009] In one possible implementation of this utility model, the connecting bracket has a first positioning part and a second positioning part, the first positioning part and the second positioning part are arranged at a distance, and the connecting bracket and the outer plate are positioned and connected through the cooperation of the first positioning part and the second positioning part.

[0010] In this way, the connection positioning between the connecting bracket and the outer plate is achieved through the cooperation of the first positioning part and the second positioning part, which can effectively control the assembly position error between the connecting bracket and the outer plate, improve the assembly accuracy between the connecting bracket and the outer plate, and reduce the assembly difficulty between the connecting bracket and the outer plate.

[0011] In one possible implementation of this utility model, the first positioning part is formed as a first positioning hole, the second positioning part is formed as a second positioning hole, and at least one of the first positioning hole and the second positioning hole is formed as a waist-shaped hole.

[0012] Thus, in the actual manufacturing and assembly process, there may be processing errors, assembly deviations or differences in thermal expansion between the connecting bracket and the inner plate. The waist-shaped hole is a non-circular through hole with semi-circular ends, a rectangular middle, and an overall "waist" or "racetrack" shape. It can be used to position the relative installation position of the connecting bracket and the inner plate and improve the assembly accuracy.

[0013] In one possible implementation of this utility model, the connecting bracket includes: a first plate, a second plate, and a third plate, the first plate, the second plate, and the third plate being connected in sequence, the first plate and the third plate both extending along the thickness direction of the second plate, and the first plate, the second plate, and the third plate defining the connecting groove.

[0014] Thus, by setting the first plate, the second plate, and the third plate, the overall rigidity of the connecting bracket is enhanced, and the bending and torsional resistance of the door anti-collision beam assembly is improved. The first plate, the second plate, and the third plate can wrap around one end of the anti-collision beam body to prevent assembly misalignment or loosening.

[0015] In one possible implementation of this utility model, a first flange is formed on the side of the first plate away from the second plate, and a first positioning part is formed on the first flange. A second flange is formed on the side of the third plate away from the second plate, and a second positioning part is formed on the second flange. A first connecting part is formed on the second plate, and the first connecting part is formed as a connecting nut. The connecting nut is fixedly connected to the second plate.

[0016] In this way, the connecting bracket achieves precise assembly and positioning of the door anti-collision beam assembly and the door through the first positioning part on the first flange and the second positioning part on the second flange, and connects to the inner panel of the door through the connecting nut fixed on the second plate. In cooperation with the first positioning part and the second positioning part, the reliable connection between the door anti-collision beam assembly and the door is improved, and the assembly efficiency between the door anti-collision beam assembly and the door is increased.

[0017] In one possible implementation of this utility model, the door anti-collision beam assembly further includes an anti-collision pin, which passes through the outer plate and is connected to the connecting bracket.

[0018] In this way, by setting anti-collision pins, the impact force generated during a collision can be further dispersed, effectively resisting deformation and improving the safety of occupants.

[0019] In one possible implementation of this utility model, the anti-collision beam body is welded to the connecting bracket.

[0020] In this way, the welded connection has high strength, which improves the rigidity between the anti-collision beam body and the connecting bracket, reduces the assembly complexity, and enhances the connection durability.

[0021] Secondly, embodiments of this application provide a door assembly, including: an inner panel, an outer panel, and a door anti-collision beam assembly provided in any of the embodiments of the first aspect above. The door anti-collision beam assembly is disposed between the inner panel and the outer panel, and is connected to both the inner panel and the outer panel.

[0022] The door assembly provided in this application includes the door anti-collision beam assembly provided in any of the embodiments of the first aspect above, and therefore has the same technical effect. That is, by cooperating with the first connecting part and the second connecting part, the connection stability between the connecting bracket and the door is improved, preventing the door anti-collision beam assembly from loosening or falling off. By nesting and fixing the connecting bracket and the anti-collision beam body, the overall rigidity of the door anti-collision beam assembly is improved, ensuring the structural strength of the vehicle while avoiding an increase in the vehicle's own weight.

[0023] Thirdly, embodiments of this application provide a vehicle including the door assembly provided in any of the embodiments of the second aspect above.

[0024] The vehicle provided in this application embodiment includes the door assembly provided in any of the embodiments of the second aspect above.

[0043] As living standards improve, people are paying increasing attention to their personal safety. When buying a car, they no longer only focus on the vehicle's appearance, performance, and comfort; safety performance, especially crash safety performance, has become a crucial consideration. Consumers are proactively researching a car's safety features and crash test ratings, tending to choose models with superior safety performance. The new versions of C-IASI 2023 and C-NCAP 2024 have raised the height and weight of the side impact barrier, while also specifying various indicators for vehicles in side collisions. This compels automakers to adopt effective measures to improve the impact resistance of car doors, making door impact beams an important technical means to meet regulatory requirements. On the one hand, it is necessary to enhance vehicle safety performance to meet the new crash test standards; on the other hand, the impact of vehicle weight on energy consumption must also be considered.

[0046] The following is for reference. Figures 1-5 This invention describes a door anti-collision beam assembly 10 according to an embodiment of the present invention.

[0047] Specifically, the door anti-collision beam assembly 10 is connected to the door. The door anti-collision beam assembly 10 includes an anti-collision beam body 1 and a connecting bracket 2. A connecting groove 21 is formed on the connecting bracket 2. At least a portion of the anti-collision beam body 1 is disposed within and fixedly connected to the connecting groove 21. A first connecting portion is formed on the bottom wall of the connecting groove 21, and a second connecting portion is formed on the door. The first connecting portion is adapted to cooperate with the second connecting portion to connect the connecting bracket 2 to the door. Thus, the cooperation between the first and second connecting portions improves the connection stability between the connecting bracket 2 and the door, preventing the door anti-collision beam assembly 10 from loosening or falling off. The nesting and fixing of the connecting bracket 2 and the anti-collision beam body 1 enhances the overall rigidity of the door anti-collision beam assembly 10, ensuring the structural strength of the vehicle while avoiding an increase in the vehicle's weight.

[0048] Understandably, the door anti-collision beam assembly 10 is a safety structure installed inside the car door, used to absorb impact energy and protect the safety of the occupants during a side collision. The door anti-collision beam includes an anti-collision beam body 1 and a connecting bracket 2. The anti-collision beam body 1 is used to withstand the impact force in a side collision and distribute it throughout the vehicle structure. The connecting bracket 2 is used to fix the anti-collision beam body 1 to the door. The connecting bracket 2 has a connecting groove 21 for accommodating a part of the anti-collision beam body 1. A first connecting part is formed on the bottom wall of the connecting groove 21, and a second connecting part is formed on the door. The second connecting part is correspondingly arranged to the first connecting part, realizing the connection between the door anti-collision beam assembly 10 and the door. This allows the door anti-collision beam assembly 10 to be more stably connected to the door, preventing the door anti-collision beam assembly 10 from detaching from the door, and also facilitating assembly and maintenance.

[0049] Furthermore, the anti-collision beam body 1 and the connecting bracket 2 can be manufactured separately, which facilitates transportation and replacement, improves production efficiency, and reduces production costs.

[0050] Reference Figures 1-5 As shown, the door anti-collision beam assembly 10 includes an anti-collision beam body 1 and a connecting bracket 2. A connecting groove 21 is formed on the connecting bracket 2. One end of the anti-collision beam body 1 is located in the connecting groove 21, and one end of the anti-collision beam body 1 is fixedly connected to the connecting groove 21 to ensure the connection stability between the anti-collision beam body 1 and the connecting bracket 2. A first connecting part is formed on the bottom wall of the connecting groove 21, and a second connecting part is formed on the door. The connecting bracket 2 and the door are connected through the first connecting part and the second connecting part.

[0051] According to the embodiment of the present utility model, the door anti-collision beam assembly 10 improves the connection stability between the connecting bracket 2 and the door by cooperating with the first connecting part and the second connecting part, preventing the door anti-collision beam assembly 10 from loosening or falling off. By nesting and fixing the connecting bracket 2 and the anti-collision beam body 1, the overall rigidity of the door anti-collision beam assembly 10 is improved, ensuring the structural strength of the vehicle while avoiding an increase in the vehicle's own weight.

[0052] In some embodiments of this utility model, the car door includes an inner panel 20 and an outer panel. A second connecting portion is formed on the inner panel 20, and a connecting bracket 2 is connected to the inner panel 20 through a first connecting portion and a second connecting portion. Therefore, by fixing the connecting bracket 2 to the inner panel 20, the overall connection strength can be improved, the force transmission efficiency during a collision can be enhanced, and the inner panel 20 has a relatively flat and stable structure, facilitating positioning and connection, which helps improve assembly consistency and precision, does not damage the integrity of the outer panel surface, and maintains the aesthetic appearance of the car door.

[0053] Reference Figure 2As shown, it can be understood that the car door has an inner panel 20 and an outer panel. A second connecting part is formed on the inner panel 20. The connecting bracket 2 is connected to the inner panel 20 through the first connecting part and the second connecting part. The connecting bracket 2 is connected to the inner panel 20 through fasteners 4.

[0054] Furthermore, the first connecting part is formed as a connecting nut 25, and the second connecting part is formed as a connecting hole 201. The connecting bracket 2 and the inner plate 20 are connected by fasteners 4 passing through the connecting hole 201 and the connecting nut 25, which reduces the difficulty of connecting the inner plate 20 and the connecting bracket 2, simplifies the connection steps between the inner plate 20 and the connecting bracket 2, and improves the assembly efficiency of the inner plate 20 and the connecting bracket 2.

[0055] Reference Figure 2 As shown, it can be understood that the connecting nut 25 is formed on the connecting bracket 2 and is located in the connecting groove 21. The connecting hole 201 is formed on the inner plate 20 and penetrates the inner plate 20 in the thickness direction. The connecting nut 25 corresponds to the connecting hole 201. The fastener 4 first passes through the connecting hole 201 of the inner plate 20, and then the fastener 4 is connected to the connecting nut 25 so that the connecting bracket 2 is connected to the inner plate 20.

[0056] In some embodiments of this utility model, the connecting bracket 2 has a first positioning part and a second positioning part, which are arranged at a distance from each other. The connecting bracket 2 and the outer plate are positioned and connected through the cooperation of the first positioning part and the second positioning part. Thus, the connection and positioning between the connecting bracket 2 and the outer plate are achieved through the cooperation of the first positioning part and the second positioning part, which can effectively control the assembly position error between the connecting bracket 2 and the outer plate, improve the assembly accuracy between the connecting bracket 2 and the outer plate, and reduce the assembly difficulty between the connecting bracket 2 and the outer plate.

It is understood that in actual manufacturing and assembly processes, there may be processing errors, assembly deviations, or differences in thermal expansion between the connection positions of the connecting bracket 2 and the inner plate 20. An oblong hole is a non-circular through hole with semi-circular ends, a rectangular middle section, and an overall "oblong" or "racetrack" shape. It can be used to position the relative installation positions of the connecting bracket 2 and the inner plate 20, improving assembly accuracy.

[0058] Reference Figure 5 As shown, the first positioning hole 28 is formed as a circular hole, and the second positioning hole 29 is formed as an oblong hole.

[0059] In some embodiments of this utility model, the connecting bracket 2 includes a first plate 22, a second plate 23, and a third plate 24. The first plate 22, the second plate 23, and the third plate 24 are connected sequentially. The first plate 22 and the third plate 24 both extend along the thickness direction of the second plate 23. The first plate 22, the second plate 23, and the third plate 24 define a connecting groove 21. Thus, by providing the first plate 22, the second plate 23, and the third plate 24, the overall rigidity of the connecting bracket 2 is enhanced, and the bending and torsional resistance of the door anti-collision beam assembly 10 is improved. The first plate 22, the second plate 23, and the third plate 24 can wrap around one end of the anti-collision beam body 1 to prevent assembly misalignment or loosening.

[0060] Reference Figure 5 As shown, it can be understood that the first plate 22 and the third plate 24 extend laterally, and the second plate 23 extends vertically. One end of the second plate 23 is connected to one end of the first plate 22, and the other end of the second plate 23 is connected to one end of the third plate 24, forming a C-shaped structure. The first plate 22, the second plate 23, and the third plate 24 define the connecting groove 21. One end of the anti-collision beam body 1 is located in the connecting groove 21, and the outer peripheral sidewall of the anti-collision beam is connected to the inner sidewall of the connecting groove 21.

[0061] In some embodiments of this utility model, a first flange 26 is formed on the side of the first plate 22 away from the second plate 23, and a first positioning part is formed on the first flange 26. A second flange 27 is formed on the side of the third plate 24 away from the second plate 23, and a second positioning part is formed on the second flange 27. A first connecting part is formed on the second plate 23, and the first connecting part is formed as a connecting nut 25. The connecting nut 25 is fixedly connected to the second plate 23. Thus, the connecting bracket 2 achieves precise assembly and positioning of the door anti-collision beam assembly 10 and the door through the first positioning part on the first flange 26 and the second positioning part on the second flange 27. It is also connected to the inner panel 20 of the door through the connecting nut 25 fixed on the second plate 23. In cooperation with the first positioning part and the second positioning part, the reliable connection between the door anti-collision beam assembly 10 and the door is improved, and the assembly efficiency between the door anti-collision beam assembly 10 and the door is increased.

[0062] In some embodiments of this utility model, such as Figure 3 As shown, the door anti-collision beam assembly 10 also includes an anti-collision pin 3, which passes through the outer panel and is connected to the connecting bracket 2. Therefore, by providing the anti-collision pin 3, the impact force generated during a collision can be further dispersed, effectively resisting deformation and improving the safety of the occupants.

[0063] In some embodiments of this utility model, the anti-collision beam body 1 and the connecting bracket 2 are welded together. This results in a high welded connection strength, improves the rigidity between the anti-collision beam body 1 and the connecting bracket 2, reduces assembly complexity, and enhances connection durability.
