Technical Field

[0001] This utility model relates to the field of automotive parts, and in particular to a door waistline reinforcement structure, a vehicle door body, and a vehicle. Background Technology

[0002] With the development of the automotive industry, the safety and comfort requirements of car door structures are constantly increasing. As an important component of a vehicle, the door not only plays a role in protecting the safety of occupants, but also directly affects the overall sealing, sound insulation, and user experience of the vehicle. To improve the structural strength and impact resistance of the door, inner and outer waistline reinforcement plates are usually installed inside the door to enhance the rigidity of the door waistline area.

[0003] However, in existing technologies, the inner and outer waistline reinforcement plates of car doors are mostly installed independently, lacking an effective connecting structure. This structural approach results in insufficient overall rigidity in the door waistline area, failing to form a cohesive framework for load-bearing. During vehicle operation or when the door is closed, especially in the rear area, noticeable vibrations and resonances can easily occur, affecting the user experience and potentially accelerating fatigue damage to door components, thus reducing the door's lifespan.

[0036] Example 1 like Figure 1 As shown, this embodiment provides a door waistline reinforcement structure, including an outer waistline reinforcement plate 2, an inner waistline reinforcement plate 1, and a connecting bracket 3; the outer waistline reinforcement plate 2 and the inner waistline reinforcement plate 1 are fixedly connected at both ends along the length direction; the connecting bracket 3 is clamped between the outer waistline reinforcement plate 2 and the inner waistline reinforcement plate 1.

[0037] In this embodiment, the connecting bracket 3 is clamped between the outer waistline reinforcing plate 2 and the inner waistline reinforcing plate 1, which can improve the connection strength between the outer waistline reinforcing plate 2 and the inner waistline reinforcing plate 1, improve the stability between the outer waistline reinforcing plate 2 and the inner waistline reinforcing plate 1, and avoid the vibration problem caused by the vibration of the outer waistline reinforcing plate 2 and the inner waistline reinforcing plate 1 when the car door is closed.

[0038] like Figure 1 and Figure 2 and Figures 4 to 6 As shown in the specific example provided in this application, both sides of the inner waistline reinforcing plate 1 are bent towards the same side along the length direction to form support plates 11. The end of each support plate 11 away from the inner waistline reinforcing plate 1 is bent again in a direction away from the inner waistline reinforcing plate 1 to form a connecting plate 12. Both ends of the outer waistline reinforcing plate 2 are respectively connected to the corresponding connecting plates 12. Specifically, the support plates 11 create a clamping space 13 between the inner waistline reinforcing plate 1 and the outer waistline reinforcing plate 2, used to clamp the connecting bracket 3. Through this clamping space 13, the connecting bracket 3 can be stably positioned between the inner waistline reinforcing plate 1 and the outer waistline reinforcing plate 2. Furthermore, this improves the stability between the outer waistline reinforcing plate 2 and the inner waistline reinforcing plate 1, avoiding the vibration problem caused by the vibration of the outer waistline reinforcing plate 2 and the inner waistline reinforcing plate 1 when the car door is closed.

[0039] Understandably, the two ends of the inner waistline reinforcing plate 1 are bent for the first time to form the support plate 11, and the support plate 11 is bent for the second time to form the connecting plate 12. The multi-layer structure formed by the two bends improves the rigidity and deformation resistance of the inner waistline reinforcing plate 1.

[0040] like Figure 8 As shown, in a specific example provided in this application, the connecting bracket 3 includes a support plate 31. The two ends of the support plate 31 are bent in opposite directions along the length direction to form a first reinforcing plate 32 and a second reinforcing plate 33, respectively. The first reinforcing plate 32 and the second reinforcing plate 33 are respectively connected to the inner waistline reinforcing plate 1 and the outer waistline reinforcing plate 2.

[0041] It is understood that the first reinforcing plate 32, the support plate 31, and the second reinforcing plate 33 form a Z-shaped connecting bracket 3. The Z-shaped connecting bracket 3 is sandwiched between the inner waistline reinforcing plate 1 and the outer waistline reinforcing plate 2, effectively improving the overall structural strength and rigidity, and enhancing impact and deformation resistance. The Z-shaped structure of the connecting bracket 3 can disperse and absorb external loads through its own geometric deformation, preventing stress concentration and improving the energy absorption and buffering performance of the door waistline reinforcing structure. Simultaneously, the Z-shaped connecting bracket 3 helps stabilize the connection between the inner waistline reinforcing plate 1 and the outer waistline reinforcing plate 2, preventing relative displacement and achieving lightweight and efficient protection of the structure. In other embodiments, the two ends of the support plate 31 are bent in the same direction along its length to form the first reinforcing plate 32 and the second reinforcing plate 33, respectively; this is not limited here.

[0042] Further reference Figure 8 The first reinforcing plate 32 is provided with at least one first reinforcing part, which includes a first reinforcing rib 321 recessed on the surface of the first reinforcing plate 32 facing the inner waistline reinforcing plate 1. Specifically, the first reinforcing rib 321 extends from the end away from the support plate 31 to the upper part of the support plate 31, improving the strength of the first reinforcing plate 32 and the connection strength between the first reinforcing plate 32 and the support plate 31. In specific installation, the first reinforcing plate 32 is attached to the inner waistline reinforcing plate 1 and fixedly connected by rivets, welding or bolts, which is not limited here.

[0043] refer to Figure 8 In this embodiment, there are two first reinforcing ribs 321, evenly distributed on the first reinforcing plate 32; in other embodiments, the number of first reinforcing ribs 321 may be three or four, etc., and this application does not limit the number of first reinforcing ribs 321. Specifically, when the first reinforcing plate 32 is fixed to the inner waistline reinforcing plate 1, the recessed area of ​​the first reinforcing plate 32 forming the first reinforcing rib 321 forms a first buffer space 15 with the inner waistline reinforcing plate 1 (see...). Figure 9 This is used to improve the impact resistance between the first reinforcing plate 32 and the inner waistline reinforcing plate 1.

[0044] like Figure 6 and Figure 9As shown in a specific example provided in this application, a boss 14 is provided on the surface of the inner waistline reinforcing plate 1 facing the first reinforcing plate 32 for mounting with the first reinforcing plate 32. Specifically, there is an arc-shaped transition between the boss 14 and the first reinforcing plate 32. It can be understood that when the inner waistline reinforcing plate 1 is impacted, the impact force is transmitted to the first reinforcing plate 32 through the boss 14. The arc-shaped transition can increase the strength between the boss 14 and the first reinforcing plate 32, improving the impact resistance and structural stability of the boss 14. The arc-shaped transition effectively avoids stress concentration caused by right-angle connections, allowing the impact load to be distributed and transmitted more smoothly, thereby reducing the risk of structural damage and extending the service life of the inner waistline reinforcing plate 1. It is worth mentioning that in other embodiments, a reinforcing part is provided on the protrusion, or a recessed part is provided in the connection area between the inner waistline reinforcing plate and the first reinforcing plate. Therefore, this application does not limit the specific structure at the connection between the inner waistline reinforcing plate 1 and the first reinforcing plate 32. Any specific structure that can improve the connection strength between the first reinforcing plate 32 and the inner waistline reinforcing plate 1 is within the protection scope of this application.

[0045] like Figure 8 As shown in a specific example provided in this application, the second reinforcing plate 33 is provided with at least one second reinforcing portion, which includes a second reinforcing rib 331 recessed on the surface of the second reinforcing plate 33 facing the outer waistline reinforcing plate 2. Specifically, the second reinforcing rib 331 extends from the end away from the support plate 31 to the upper part of the support plate 31, improving the strength of the second reinforcing plate 33 and the connection strength between the second reinforcing plate 33 and the support plate 31. In specific installation, the second reinforcing plate 33 is attached to the outer waistline reinforcing plate 2 and fixedly connected by rivets, welding or bolts, which is not limited here.

[0046] like Figure 5 As shown, in a specific example provided in this application, a groove 21 is provided on the surface of the outer waistline reinforcing plate 2 facing the second reinforcing plate 33 for installation with the second reinforcing plate 33. It is understood that the groove 21 provides accurate positioning and a stable installation foundation for the second reinforcing plate 33. Furthermore, the groove 21 helps the outer waistline reinforcing plate 2 to distribute and transfer external loads, avoiding stress concentration in a single area and reducing the risk of structural damage. It is worth mentioning that in other embodiments, a protrusion is provided in the area where the outer waistline reinforcing plate 3 connects to the second reinforcing plate 33 to increase the connection strength between the outer waistline reinforcing plate 3 and the second reinforcing plate 33. Therefore, this application does not limit the specific structure of the connection between the outer waistline reinforcing plate 2 and the second reinforcing plate 33; any specific structure that can improve the connection strength between the second reinforcing plate 33 and the outer waistline reinforcing plate 1 is within the protection scope of this application.

[0047] Further reference Figure 8In this embodiment, there are two second reinforcing ribs 331, evenly distributed on the second reinforcing plate 33; in other embodiments, the number of second reinforcing ribs 331 may be three or four, etc., and this application does not limit the number of second reinforcing ribs 331. Specifically, when the second reinforcing plate 33 is fixed to the outer waistline reinforcing plate 2, a second buffer space 23 is formed between the recessed area of ​​the second reinforcing plate 33 forming the second reinforcing ribs 331 and the outer waistline reinforcing plate 2 (see...). Figure 5 and Figure 10 This is used to improve the impact resistance between the second reinforcing plate 33 and the outer waistline reinforcing plate 2.

[0048] refer to Figure 5 and Figure 7 The bottom of the sink 21 is provided with a third reinforcing part, which includes a third reinforcing rib 22 formed by a recess at the bottom of the sink 21 away from the second reinforcing plate 33. Specifically, the number of third reinforcing ribs 22 is the same as the number of second reinforcing ribs 331, and each third reinforcing rib 22 corresponds to one second reinforcing rib 331. When the second reinforcing plate 33 is fixedly connected to the outer waistline reinforcing plate 2, the recessed area at the bottom of the sink 21 forming the third reinforcing rib 22 is connected to the second buffer space 23, further improving the connection strength between the second reinforcing plate 33 and the outer waistline reinforcing plate 2, as well as the impact resistance.

[0049] Example 2 like Figure 11 As shown, this embodiment provides a vehicle door body, including the door waistline reinforcement structure of Embodiment 1. Specifically, the inner waistline reinforcement plate 1 is fixedly connected to the inner door panel 4 by welding or riveting, and the outer door panel (not shown in the figure) is fixedly connected to the outer waistline reinforcement plate 2 by welding or riveting. In this embodiment, the door waistline reinforcement structure is set at the waistline of the door. Through the inner waistline reinforcement plate 1, the outer waistline reinforcement plate 2, and the clamping structure between them, the overall strength and deformation resistance of the vehicle door body under external impact are effectively improved. This enhances the structural stability and safety performance of the vehicle door body and improves the passive safety protection level of the entire vehicle.

[0050] Example 3 This embodiment provides a vehicle, including the door body of the vehicle in Embodiment 2. Specifically, the left and right front doors and / or rear doors of the vehicle can all adopt the aforementioned door with integrated door waistline reinforcement structure. By providing this waistline reinforcement structure in the door body of the vehicle, the impact resistance and structural integrity of the entire vehicle under the action of external forces such as side collisions can be significantly improved, effectively protecting the safety of occupants.

[0051] The vehicle in this embodiment significantly improves its safety performance and structural reliability by adopting a door body with an integrated waistline reinforcement structure, which has good practical value and market application prospects.

[0052] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
