Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0025] According to a first aspect of this utility model, a reinforced structure based on small offset collision safety is provided, such as... Figures 1 to 8As shown, this reinforcement structure based on small offset collision safety is installed on a vehicle to reinforce the Shotgun area, thereby improving the impact strength at that location and protecting the door hinge pillar 2. The vehicle may include a collision area component 1, a door hinge pillar 2, and an outer side panel 3. The collision area component 1 is the Shotgun area component. All three components—collision area component 1, door hinge pillar 2, and outer side panel 3—are existing components connected to each other. Since the rear end of the collision area component 1 and the door hinge pillar 2 are hollow structures in conventional vehicle body designs, severe compression could lead to a serious risk of sheet metal fracture failure in the upper part of the door hinge pillar 2, resulting in head and chest injuries to the occupants. Therefore, this improved reinforcement structure based on small offset collision safety ensures occupant safety.

[0026] The reinforced structure based on small offset collision safety includes a first reinforcing member 4 and a second reinforcing member 5. In the following description, reference will be made to... Figures 1 to 8 This section describes the detailed structure of the first reinforcing member 4 and the second reinforcing member 5 of the reinforced structure based on small offset collision safety. Furthermore, as... Figure 6 and Figure 8 As shown, the description of the embodiment also involves a second direction S2 and a first direction S1. The first direction S1 and the second direction S2 can be understood as a horizontal direction and a vertical direction, respectively. The horizontal direction is the direction from the front of the vehicle to the rear of the vehicle or from the rear of the vehicle to the front of the vehicle, and the vertical direction is the direction perpendicular to the vehicle body.

[0027] like Figures 1 to 8 As shown, in the embodiment, the collision area component 1 is disposed at the end of the outer side plate 3, the outer side plate 3 is disposed on the outside of the door ring hinge post 2, the first reinforcing member 4 is disposed on the collision area component 1, and the second reinforcing member 5 is disposed on the door ring hinge post 2.

[0028] Specifically, a collision cavity is formed between the first reinforcing member 4, the collision area component 1, and the outer side plate 3. The first reinforcing member 4 is located on the inner side of the collision area component 1 (the outer side plate 3 is located on the outer side of the door ring hinge column 2, and the inner side of the first reinforcing member 4 is located on the inner side relative to the location of the outer side plate 3), which can support the collision area component 1 and improve the collision strength at that point. At the same time, since the collision cavity is formed between the first reinforcing member 4, the collision area component 1, and the outer side plate 3, the cavity in the original structure is still formed among these three components, thus achieving the purpose of absorbing collision kinetic energy. The second reinforcing member 5 includes two reinforcing ends 501 provided in the first direction S1. The reinforcing ends 501 abut against the inner wall of the door ring hinge column 2 to provide support in the first direction S1. In the later stages of a small offset collision, the vehicle's impact zone component 1 and the first reinforcement 4 will be impacted first. After the impact cavity formed between the first reinforcement 4, the impact zone component 1, and the outer side plate 3 is fully absorbed, the impact force on the upper part of the door hinge pillar 2 will be reduced. Then, through the structure of the door hinge pillar 2 itself and the front and rear supports of the second reinforcement 5, it is ensured that the sheet metal at the upper end of the door hinge pillar 2 will not tear during the small offset collision, thereby avoiding damage to the passenger compartment and protecting the personal safety of the occupants. In addition, the first reinforcement 4, the second reinforcement 5, the impact zone component 1, and the outer side plate 3 can be fixed by welding.

[0029] This small offset collision safety-based reinforcement structure, through the arrangement of the first reinforcement member 4 and the second reinforcement member 5, forms a collision cavity between the first reinforcement member 4, the collision area component 1, and the outer side plate 3. The second reinforcement member 5 provides reinforced support to the upper end of the door ring hinge pillar 2, thereby effectively distributing the impact force in the later stages of the collision, protecting the structural integrity of the passenger compartment, and thus improving occupant safety during a collision. This small offset collision safety-based reinforcement structure has a simple overall structure, is easy to assemble, and can effectively ensure the structural strength of the vehicle's shotgun area.

[0030] Preferably, such as Figures 1 to 6 As shown, in this embodiment, the collision region component 1 includes a first protrusion, and the first reinforcing member 4 includes a second protrusion 401. The first and second protrusions 401 protrude in opposite directions to form a collision cavity. The two protrusions with opposite directions abut each other, forming a collision cavity for energy absorption. Compared to the single collision region component 1 in the original structure, the collision cavity formed by the first reinforcing member 4 and the collision region component 1 can further improve the energy absorption effect and thus increase the collision strength. Furthermore, to further improve the energy absorption effect and collision strength, the second protrusion 401 is formed with a plurality of bends 402 spaced apart from each other.

[0031] Preferably, such as Figures 1 to 6As shown, in the embodiment, the first reinforcing member 4 may further include a first abutting edge 403 and abutting edge 404. The first abutting edge 403 and the second abutting edge 404 are respectively disposed at both ends of the second protrusion 401 in the second direction S2. The first abutting edge 403 and the second abutting edge 404 abut against the collision area member 1. The first reinforcing member 4 is welded to the collision area member 1 through the first abutting edge 403 and the second abutting edge 404.

[0032] Preferably, such as Figures 1 to 6 As shown, in this embodiment, the first reinforcing member 4 has a third abutting edge 405 at its end near the door ring hinge post 2 in the first direction S1, and the first reinforcing member 4 abuts against the door ring hinge post 2 through the third abutting edge 405. The first reinforcing member 4 is welded to the side wall of the door ring hinge post 2 in the first direction S1 through the third abutting edge 405.

[0033] Preferably, such as Figures 1 to 6 As shown in the embodiment, the second protrusion 401, the first abutment edge 403, and the second abutment edge 404 are all provided with multiple structural process holes 6 and matching grooves 7. The arrangement of the multiple structural process holes 6 and matching grooves 7 is designed according to the crushing and bending characteristics of the area where they are located, which can ensure energy absorption effect and structural strength.

[0034] Preferably, such as Figures 1 to 4 , Figure 7 and Figure 8 As shown, in this embodiment, the second reinforcing member 5 may include an abutting plate portion 502 and a plurality of surrounding plate portions 503. One end of the surrounding plate portion 503 is connected to one end of the abutting plate portion 502. The plurality of surrounding plate portions 503 are connected end to end and surround the abutting plate portion 502. The abutting plate portion 502 and the plurality of surrounding plate portions 503 make the second reinforcing member 5 form a box-shaped structure. The box-shaped structure can effectively improve the support strength of the front and rear ends, thereby improving the sheet metal strength of the door ring hinge post 2 itself and preventing it from breaking due to impact. The abutting plate portion 502 abuts against the door ring hinge post 2, and the reinforcing end 501 of the second reinforcing member 5 is the surrounding plate portion 503 in the first direction S1. The surrounding plate portion 503 abuts against the door ring hinge post 2 to form a reinforcing end 501, thereby improving the structural strength at that location.

[0035] Preferably, such as Figures 1 to 4 , Figure 7 and Figure 8 As shown in the embodiment, multiple structural process holes 6 and matching grooves 7 are provided at the connection between the abutment plate portion 502 and the surrounding plate portion 503, as well as at both the abutment plate portion 502 and the surrounding plate portion 503. Similarly, the structural process holes 6 and matching grooves 7 provided in the second reinforcing member 5 serve the same purpose as those provided in the first reinforcing member 4, and are designed based on the crushing and bending characteristics of their respective areas to ensure energy absorption effect and structural strength.

[0036] Preferably, such as Figures 1 to 4 , Figure 7 and Figure 8 As shown, in the embodiment, since the second reinforcing member 5 needs to be installed at the location where the wire harness needs to be threaded, the enclosure plate portion 503 in the second direction S2 has a wire hole 504.

[0037] Preferably, such as Figures 1 to 4 , Figure 7 and Figure 8 As shown, in the embodiment, a fourth abutting edge 505 is provided on the side of the enclosure plate portion 503 away from the abutting plate portion 502 in the second direction S2. The fourth abutting edge 505 abuts against the inner plate of the door ring hinge column 2 to ensure the connection strength at that point.

[0038] The reinforced structure based on small offset collision safety adds a first reinforcing member 4 inside the collision area component 1. The first reinforcing member 4 is designed in the opposite direction to the protruding structure of the collision area component 1 and is welded to the collision area component 1 and the outer side plate 3 to form a collision cavity. The first reinforcing member 4 is locally grooved and perforated to ensure the matching of front and rear stiffness and the stability of deformation. A second reinforcing member 5 is added inside the door ring hinge column 2. The second reinforcing member 5 forms a box-shaped structure through self-welding. The box-shaped structure forms front and rear support inside the door ring hinge column 2 and is connected to it by welding.

[0039] This small offset collision safety-based reinforcement structure, through the arrangement of a first and a second reinforcement member, creates a collision cavity between the first reinforcement member, the collision area components, and the outer side panels. The second reinforcement member provides enhanced support to the upper end of the door hinge pillar, effectively distributing the impact force in the later stages of the collision, protecting the structural integrity of the passenger compartment, and thus improving occupant safety during a collision. This small offset collision safety-based reinforcement structure has a simple overall structure, is easy to assemble, and effectively ensures the structural strength of the vehicle's shotgun area.

[0040] Furthermore, according to a second aspect of the present invention, a vehicle is provided, the vehicle including the reinforced structure based on small offset collision safety as described above.
