Description

Technical Field

[0001] The present application relates to the field of automobile bodies, and in particular to a body structure and a vehicle for protecting pedestrians' heads. Background Art

[0002] With the development of modern automobiles, people have higher and higher requirements for the appearance and quality of automobiles. While meeting user needs, based on road traffic safety considerations and in order to reduce the casualty rate in vehicle-to-pedestrian collision accidents, my country's automobile-to-pedestrian collision protection regulations are becoming increasingly perfect and upgraded. Pedestrian protection is also included in the C-NCAP assessment. The pedestrian collision area mainly occurs at the front of the car, and the pedestrian protection performance of the front of the car is related to the front structural design of the car.

[0003] In traffic accidents involving collisions between vehicles and pedestrians, the hood hinge area often causes significant head damage due to its small impact cushioning space and high local stiffness. This area is also a challenging area during vehicle design and development, representing a high probability of failing to meet crash protection regulations.

[0004] To meet crash protection regulations, car designers can manipulate the hood hinge area's shape, lowering the hinge's hardpoint or raising the car's exterior surface to increase head impact cushioning to reduce pedestrian head injuries. However, this imposes significant challenges and limitations on the vehicle's styling and hardpoint placement.

[0005] In order not to affect the styling design, some car manufacturers will adopt an active pop-up hood system. That is, when a pedestrian collision occurs, the rear of the hood will actively pop up to increase the buffer space. However, the development cost of the active pop-up hood system is high and it is not easy for consumers to accept it. Summary of the Invention

[0023] To make the purpose, technical solutions, and advantages of the embodiments of this application more clear, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0024] The embodiments of the present application provide a vehicle body structure and vehicle for protecting pedestrians' heads, which can solve the problem in related technologies that the hinge area of ​​the engine hood usually causes serious damage to pedestrians' heads due to the small collision buffer space and high local stiffness.

[0025] See also Figures 1 to 6 As shown, a first aspect of an embodiment of the present application provides a vehicle body structure for protecting a pedestrian's head, comprising: The vehicle body includes upper longitudinal beams 5 located on the left and right sides of the engine cabin, the rear ends of the upper longitudinal beams 5 are connected to the A-pillars of the vehicle body, and an engine hood 7 located above the upper longitudinal beams 5 for opening or closing the engine cabin.

[0026] The hood hinge 3 includes a hinge seat 32 and a hinge arm 31 connected between the upper longitudinal beam 5 and the engine hood 7. The hinge seat 32 and the hinge arm 31 are rotatably connected to each other so that the engine hood 7 opens or closes the cabin. A vertical space is provided between the engine hood 7 and the hinge seat 32.

[0027] The fender connecting member includes a fender bracket 4 fixed to the upper longitudinal beam 5 and a fender mounting plate 6 fixed to the fender bracket 4. The fender bracket 4 and the fender mounting plate 6 are used to support and install the fenders located on both sides of the cabin.

[0028] The cabin rear decorative panel 2 is located in the vertical space, the top of the cabin rear decorative panel 2 supports the engine hood 7, and the bottom of the cabin rear decorative panel 2 is respectively connected to the fender mounting plate 6 and the hinge seat 32.

[0029] When the vehicle body structure for protecting pedestrian heads of the embodiment of the present application is subjected to a pedestrian head collision test, the head-shaped impactor 1 first contacts the engine hood 7. The engine hood 7 is deformed downward by the impact of the head-shaped impactor 1, and then impacts the rear decorative panel 2 of the cabin. The bottom of the rear decorative panel 2 of the cabin extends downward and is respectively connected to the fender mounting plate 6 and the hinge seat 32.

[0030] When the impact energy of the head-shaped impactor 1 is transmitted to the cabin rear decorative panel 2, since the cabin rear decorative panel 2 is supported on the hinge seat 32, the rear part of the cabin rear decorative panel 2 can absorb the impact energy by bending and deforming, thereby preventing the engine hood 7 from directly hitting the hood hinge 3, and protecting the pedestrian's head from being injured by the hood hinge 3.

[0031] The front part of the rear cabin decorative panel 2 of the embodiment of the present application is supported on the top of the upper longitudinal beam 5 through the fender mounting plate 6 and the fender bracket 4. After being impacted by a collision, the fender mounting plate 6 and the fender bracket 4 can bend and deform to absorb the impact energy, further protecting the pedestrian's head and further reducing the impact damage to the pedestrian's head.

[0032] The embodiment of the present application not only does not affect the exterior design of the vehicle, but also does not add a high-cost active hood system. It only improves the energy absorption and collapse effect of the hood hinge area during pedestrian collisions through structural design, reduces damage to pedestrians' heads, and thus meets the requirements of collision protection regulations.

[0033] In some alternative embodiments: See Figures 1 to 6 As shown, an embodiment of the present application provides a vehicle body structure for protecting pedestrians' heads, wherein the hinge seat 32 of the vehicle body structure is fixedly connected to the upper longitudinal beam 5, one end of the hinge arm 31 is fixedly connected to the engine hood 7, and the other end of the hinge arm 31 is rotatably connected to the hinge seat 32 via a hinge shaft.

[0034] The cabin rear decorative panel 2 extends along the length direction of the upper longitudinal beam 5 , the bottom of the rear end of the cabin rear decorative panel 2 is engaged with the hinge seat 32 , and the bottom of the front end of the cabin rear decorative panel 2 is fixedly connected to the fender mounting plate 6 .

[0035] The hinge seat 32 of the embodiment of the present application is fixedly connected to the upper longitudinal beam 5, one end of the hinge arm 31 is fixedly connected to the engine hood 7, and the other end of the hinge arm 31 is rotatably connected to the hinge seat 32 through a hinge shaft, so that the engine hood 7 can be flipped up and down around the upper longitudinal beam 5 with the hinge shaft as the rotating axis, thereby realizing the engine hood 7 opening or closing the cabin.

[0036] The bottom of the rear end of the cabin rear decorative panel 2 is clamped and fixed with the hinge seat 32, which facilitates the quick installation of the cabin rear decorative panel 2 and the hinge seat 32. The bottom of the front end of the cabin rear decorative panel 2 is fixedly connected with the fender mounting plate 6, which facilitates the fixing of the cabin rear decorative panel 2 on the fender mounting plate 6 and improves the structural stability of its installation.

[0037] In some alternative embodiments: See Figures 1 to 6 As shown, an embodiment of the present application provides a body structure for protecting pedestrians' heads, wherein the top of the cabin rear decorative panel 2 of the body structure is provided with a flange supporting the engine hood 7, the bottom of the front end of the cabin rear decorative panel 2 is provided with a clip connected to the fender mounting plate 6, and the bottom of the rear end of the cabin rear decorative panel 2 is provided with a slot 21 that is engaged with the hinge seat 32.

[0038] The embodiment of the present application is provided with a flange supporting the engine hood 7 at the top of the cabin rear decorative panel 2. The flange is used to vertically support the engine hood 7. When a pedestrian's head hits the engine hood 7, the engine hood 7 collapses and deforms downward until the impact force is transmitted to the flange at the top of the cabin rear decorative panel 2, and then the cabin rear decorative panel 2 collapses and deforms to cushion the impact force on the pedestrian's head.

[0039] The bottom of the front end of the cabin rear decorative panel 2 is provided with a clip connected to the fender mounting plate 6, and the bottom of the rear end of the cabin rear decorative panel 2 is provided with a slot 21 that is connected to the hinge seat 32. The clip and the slot 21 are both used to conveniently and quickly install and fix the cabin rear decorative panel 2 on the fender mounting plate 6 and the hinge seat 32, thereby improving the efficiency of the installation operation.

[0040] In some alternative embodiments: See Figures 1 to 6 As shown, an embodiment of the present application provides a vehicle body structure for protecting pedestrians' heads. The fender bracket 4 of the vehicle body structure includes a vertical plate fixedly connected to the side wall of the upper longitudinal beam 5, and a horizontal plate connected to the fender mounting plate 6. The vertical plate and the horizontal plate are interconnected to form an inverted "L"-shaped structure.

[0041] Specifically, the vertical plate and horizontal plate are integrally stamped from steel plates, with vertical reinforcing ribs stamped into the vertical plate. The vertical plate is riveted to the sidewalls of the upper longitudinal beam 5. The fender bracket 4 of this embodiment comprises a vertical plate fixedly connected to the sidewalls of the upper longitudinal beam 5 and a horizontal plate connected to the fender mounting plate 6. The horizontal plate is cantilevered relative to the vertical plate, allowing it to collapse and deform under the impact force transmitted by the fender mounting plate 6, thereby mitigating damage to pedestrians' heads.

[0042] In some alternative embodiments: See Figures 1 to 6 As shown, an embodiment of the present application provides a vehicle body structure for protecting pedestrians' heads, wherein the fender mounting plate 6 of the vehicle body structure extends along the length direction of the upper longitudinal beam 5, and a plurality of grooves and protrusions are stamped on the fender mounting plate 6, which are interconnected and extend along the length direction of the fender mounting plate 6.

[0043] The grooved bottom surface of the fender mounting plate 6 is detachably connected to the top surface of the fender bracket 4 via bolts, while the raised top surface of the fender mounting plate 6 abuts against the bottom of the cabin rear trim panel 2. The fender mounting plate 6 of the present embodiment is stamped with multiple grooves and protrusions, which give the fender mounting plate 6 a corrugated structure.

[0044] As a result, under the impact force transmitted from the rear cabin decorative panel 2, the fender mounting plate 6 collapses and deforms, further mitigating the damage to the pedestrian's head.

[0045] In some alternative embodiments: See Figures 1 to 6 As shown, an embodiment of the present application provides a vehicle body structure for protecting pedestrians' heads, wherein a support seat connected to the fender mounting plate 6 is provided at one end of the cabin rear decorative panel 2 of the vehicle body structure close to the fender mounting plate 6, and the support seat and the cabin rear decorative panel 2 are connected by a plurality of vertical ribs.

[0046] The cabin rear trim panel 2 is a one-piece injection-molded component, which provides excellent collapse and deformation resistance, enhancing its energy absorption. The sidewalls of the cabin rear trim panel 2 are equipped with multiple parallel reinforcing ribs that extend along the length of the panel. The panel is located outside the hood hinge 3 to shield it from view.

[0047] A second aspect of an embodiment of the present application provides a vehicle, comprising a vehicle body structure for protecting a pedestrian's head as described in any of the above embodiments.

[0048] How it works An embodiment of the present application provides a body structure and vehicle for protecting pedestrians' heads. Since the body structure for protecting pedestrians' heads of the present application is provided with a body, the body includes upper longitudinal beams 5 located on both sides of the cabin, and a hood 7 located above the upper longitudinal beams 5 for opening or closing the cabin; a hood hinge 3, the hood hinge 3 includes a hinge seat 32 and a hinge arm 31 connected between the upper longitudinal beams 5 and the hood 7, and a vertical space is provided between the hood 7 and the hinge seat 32; a fender connector, the fender connector includes a fender bracket 4 fixed on the upper longitudinal beam 5 and a fender mounting plate 6 fixed on the fender bracket 4; a cabin rear decorative panel 2, the cabin rear decorative panel 2 is located in the vertical space, the top of the cabin rear decorative panel 2 supports the hood 7, and the bottom of the cabin rear decorative panel 2 is respectively connected to the fender mounting plate 6 and the hinge seat 32.

[0049] Therefore, when the vehicle body structure for protecting pedestrian heads of the present application is subjected to a pedestrian head collision test, the head-shaped impactor 1 first contacts the hood 7. The hood 7 is deformed downward by the impact of the head-shaped impactor 1 and then impacts the cabin rear trim panel 2. The bottom of the cabin rear trim panel 2 extends downward and is connected to the fender mounting plate 6 and the hinge seat 32. When the impact energy of the head-shaped impactor 1 is transmitted to the cabin rear trim panel 2, since the cabin rear trim panel 2 is supported on the hinge seat 32, the rear portion of the cabin rear trim panel 2 can absorb the impact energy through bending deformation, thereby preventing the hood 7 from directly impacting the hood hinge 3, thereby protecting the pedestrian's head from being injured by the hood hinge 3.

[0050] The front portion of the cabin rear trim panel 2 of this application is supported on the top of the upper longitudinal beam 5 via a fender mounting plate 6 and a fender bracket 4. Upon impact, both the fender mounting plate 6 and the fender bracket 4 are designed to bend and deform to absorb impact energy, further protecting pedestrians' heads. This application not only does not impact the vehicle's exterior design, but also avoids the need for a costly active hood system. Instead, the structural design enhances the energy-absorbing and collapsing properties of the hood hinge area during pedestrian collisions, minimizing damage to pedestrians' heads and thus meeting the requirements of collision protection regulations.
