[0027] In order to enable those skilled in the art of the present technology to better understand the solution of this application, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of this application. Obviously, the described embodiments are only a part of the embodiments of this application, rather than all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of this application.

[0028] The embodiments of this application provide a pedestrian protection device and an automobile thereof, which can solve the problem that when a pedestrian's head collides with the outer structure area of the upper front part of the automobile, the impact force acts on the pedestrian's head in the opposite direction, resulting in a relatively high head injury value.

[0029] With the official implementation of the GB24550-2024 "Collision Protection of Automobiles for Pedestrians" regulation on January 1, 2025, domestic automobile design will face more stringent challenges in pedestrian protection performance. The outer structure of the upper front part of the automobile includes the engine hood, engine compartment cover, headlamp and other accessories. Since this area is at the edge of the vehicle and the layout space is limited, at the same time, the headlamp is generally fixedly connected to the rigid frame of the vehicle body. When a pedestrian's head collides with this area of the vehicle, the collision energy cannot be fully absorbed by the deformation of the engine hood, resulting in the impact force acting on the pedestrian's head in the opposite direction and causing a relatively high head injury value. Aiming at the problem that when a pedestrian's head collides with the outer structure area of the upper front part of the automobile, the impact force acts on the pedestrian's head in the opposite direction and causes a relatively high head injury value. Refer to Figures 1 to 6 , on the first hand, the embodiments of this application provide a pedestrian protection device, which includes: an engine hood assembly 1, an engine compartment cover 2 and a headlamp 3. The engine hood assembly 1 includes an outer engine hood panel 11 and an inner engine hood panel 12. A first energy absorption structure is provided between the outer engine hood panel 11 and the inner engine hood panel 12; the engine compartment cover 2 is arranged below the engine hood assembly 1, and a safety gap is formed between the engine compartment cover 2 and the engine hood assembly 1. A second energy absorption structure is arranged in the safety gap, and the second energy absorption structure is arranged below the first energy absorption structure; the headlamp 3 is arranged below the engine compartment cover 2 and is connected to the engine compartment cover 2 by a buckle.

[0030] In this application, by arranging a first energy absorption structure in the limited space between the outer engine hood panel 11 and the inner engine hood panel 12 and arranging a second energy absorption structure in the limited space between the engine compartment cover 2 and the engine hood assembly 1, when a pedestrian's head impacts the outer engine hood panel 11 of the engine hood assembly 1, the impact force is transmitted downward along the first energy absorption structure, the second energy absorption structure and the engine compartment cover 2 to in front of the headlamp 3, and the collision energy is absorbed successively, greatly reducing the injury value of the pedestrian's head.

[0031] In this embodiment, two energy-absorbing and force-transmitting paths are designed. One is the energy-absorbing and force-transmitting path composed of the first energy-absorbing structure, the second energy-absorbing structure, the engine compartment cover 2, and the headlamp 3, that is, transmitting force downward; the other is the energy-absorbing and force-transmitting path provided on the first energy-absorbing structure along the vehicle body width direction, that is, transmitting force to both sides of the first energy-absorbing structure along the vehicle body width direction. Through the two energy-absorbing and force-transmitting paths, the engine hood assembly 1 can fully absorb the collision energy through deformation.

[0032] Based on the above embodiment, in this embodiment, the first energy-absorbing structure includes: an inner panel bracket 13 and an adhesive. The inner panel bracket 13 is fixed to the top end of the engine hood inner panel 12, and along the vehicle body width direction, an energy-absorbing and force-transmitting path is provided on the inner panel bracket 13; the adhesive is bonded between the inner panel bracket 13 and the engine hood outer panel 11.

[0033] Specifically, the inner panel bracket 13 is disposed between the engine hood outer panel 11 and the engine hood inner panel 12, and the inner panel bracket 13 is disposed along the vehicle body width direction. Therefore, the inner panel bracket 13 can not only absorb the downward collision energy and transmit the collision energy to the side of the engine hood inner panel 12, but also transmit the collision energy along its own length direction after absorbing the collision energy.

[0034] Wherein, the inner panel bracket 13 includes: a bracket body 130, a force-transmitting guiding rib 132, a force-transmitting guiding hole 133, and a reinforcing rib group.

[0035] The bracket body 130 is disposed on the engine hood inner panel 12 along the vehicle body width direction. As an installation base, structures such as the force-transmitting guiding rib 132 and the force-transmitting guiding hole 133 can be provided on the surface of the bracket body 130; the force-transmitting guiding rib 132 is disposed on the bracket body 130, and the length extension direction of the force-transmitting guiding rib 132 is the same as the vehicle body width direction; the force-transmitting guiding hole 133 is disposed on the bracket body 130 and is adjacent to the force-transmitting guiding rib 132; reinforcing rib groups are disposed on both sides of the bracket body 130, and the length extension lines of the reinforcing rib groups intersect with the length extension line of the force-transmitting guiding rib 132.

[0036] In this embodiment, since the reinforcing rib group includes: a front reinforcing rib 136 and a rear reinforcing rib 137. Therefore, a plurality of force-transmitting guiding ribs 132 are provided on one side of the front reinforcing rib 136, and a plurality of force-transmitting guiding ribs 132 are also provided on one side of the rear reinforcing rib 137. For the convenience of distinction, the plurality of force-transmitting guiding ribs 132 provided on one side of the front reinforcing rib 136 are called the first force-transmitting guiding ribs, and the plurality of force-transmitting guiding ribs 132 provided on one side of the rear reinforcing rib 137 are called the second force-transmitting guiding ribs.

[0037] More specifically, in this embodiment, reinforcing rib groups are fixed on both sides of the bracket body 130, that is, a front reinforcing rib 136 and a rear reinforcing rib 137 are fixed on both sides. Therefore, two first force transmission guiding ribs are provided, corresponding to the front reinforcing ribs 136 on both sides of the bracket body 130 respectively, and two second force transmission guiding ribs are provided, corresponding to the rear reinforcing ribs 137 on both sides of the bracket body 130 respectively. When a pedestrian's head collides, the collision energy is transmitted to the direction of the reinforcing rib group as much as possible through the force transmission guiding rib 132 and the force transmission guiding hole 133, and at the same time, the curve of the head acceleration effectively absorbs energy in the initial stage.

[0038] Further, the front reinforcing rib 136 is fixed to the bracket body 130, and there is an angle between the front reinforcing rib 136 and the horizontal plane, and the angle is an acute angle. In this embodiment, the direction of the front reinforcing rib 136 is basically kept roughly consistent with the impact direction of the head. According to the height of the vehicle model, the horizontal plane angle is designed to be between 45° and 60°. The rear reinforcing rib 137 is fixed to the bracket body 130 and is vertically arranged on one side of the front reinforcing rib 136.

[0039] Wherein, deformation guiding flanges 138 are arranged in the middle of the front reinforcing rib 136 and the rear reinforcing rib 137 respectively, so that the front reinforcing rib 136 and the rear reinforcing rib 137 both form a stepped structure. During the collision of a pedestrian's head, deformation energy absorption occurs successively on the front reinforcing rib 136 and deformation energy absorption occurs successively on the rear reinforcing rib 137, gradually reducing the value of the head acceleration curve.

[0040] An inner panel welding joint surface 135 is arranged between the front reinforcing rib 136 and the rear reinforcing rib 137, and is fixedly welded to the inner panel 12 of the engine hood through the inner panel welding joint surface 135, increasing the contact area between the inner panel 12 of the engine hood and the inner panel bracket 13.

[0041] Further, the inner panel bracket 13 further includes: a fitting portion 131, a counterbore 139 and a flanging surface 134. The fitting portion 131 is arranged on the bracket body 130, and the bonding member is bonded to the fitting portion 131; the counterbore 139 is arranged on the bracket body 130, and the counterbore 139 is fixed to the inner panel 12 of the engine hood; one end of the bracket body 130 is bent to form a flanging surface 134, and there is a gap between the flanging surface 134 and the inner panel 12 of the engine hood.

[0042] Specifically, the fitting portion 131 is arranged in the middle of the bracket body 130 and protrudes from the surface of the bracket body 130. The top end of the fitting portion 131 is a fitting surface, and the fitting surface is consistent with the curved surface of the outer panel 11 of the engine hood and there is a distance between the fitting surface and the outer panel 11 of the engine hood for installing the bonding member. In this embodiment, the bonding member is selected as the expansion film 14, and the distance between the fitting surface and the outer panel 11 of the engine hood is 3 mm.

[0043] In this embodiment, both the counterbore 139 and the flanging surface 134 need to be arranged in cooperation with the inner panel 12 of the engine hood. Among them, the inner panel 12 of the engine hood includes a sealing strip mounting surface 121, an inner panel vertical surface 123, and an inner panel bottom surface 122. A safety gap is formed between the sealing strip mounting surface 121 and the engine compartment covering member 2; the inner panel vertical surface 123 is connected to the sealing strip mounting surface 121; the inner panel bottom surface 122 is connected to the inner panel vertical surface 123. The inner panel bottom surface 122 is lower than the sealing strip mounting surface 121, and the first energy absorption structure is arranged above the inner panel bottom surface 122. Such an arrangement is beneficial for the head form to roll during the collision between the pedestrian's head and the vehicle, reducing head injuries. An opening 124 is provided on the inner panel vertical surface 123, which can weaken the strength of the inner panel vertical surface 123; and at the position of the opening 124, a flap 125 extending towards the inner panel bracket 13 is provided at one end of the inner panel vertical surface 123. The main function of the counterbore 139 provided on the bracket body 130 is to strengthen the front stiffness of the inner panel bracket 13, and it can have a certain supporting strength at the initial stage of collision energy absorption. The counterbore 139 is welded and fixed to the flap 125 on the inner panel 12 of the engine hood, which can ensure sufficient torsional stiffness. When the counterbore 139 transmits the collision force to the flap 125 on the inner panel 12 of the engine hood, the flap 125 deforms and absorbs energy.

[0044] The flanging surface 134 is located at the front of the inner panel bracket 13 and above the sealing strip mounting surface 121 of the inner panel 12 of the engine hood, and maintains a 3-mm gap from the sealing strip mounting surface 121. During the collision of the pedestrian's head, when the flanging surface 134 hits the sealing strip mounting surface 121, it deforms and absorbs energy, which can reduce head injuries and at the same time has the effect of accelerating the rolling of the head.

[0045] It should also be noted that, compared with the traditional bracket body 130 arranged front and back on the sealing strip mounting surface 121, in this application, the reinforcing rib groups on both sides of the bracket body 130 are welded to the inner panel bottom surface 122 through the inner panel welding joint surface 135, and the left and right arranged reinforcing rib groups deform more thoroughly during the collision.

[0046] On the basis of the above embodiment, in this embodiment, the second energy absorption structure is provided and includes a sealing strip structure 4. A 10-mm safety gap is left between the inner panel 12 of the engine hood and the engine compartment covering member 2 in the engine hood assembly 1, and the sealing strip structure 4 is arranged in the safety gap. Here, the sealing strip structure 4 not only plays a sealing role but also has a certain buffering and energy absorption effect, and absorbs energy by the downward deformation of the inner panel 12 of the engine hood during the collision.

[0047] Since the pedestrian head injury value mainly depends on two factors, namely the impact force and the duration, in this application, in combination with Figure 6The head impact acceleration curve and the injury value curve further illustrate the role played by the present application during the collision: In the figure, the solid curve A and the dashed curve B are respectively the head impact acceleration curves with and without the inner panel bracket 13; from the acceleration curve, the curve without the inner panel bracket 13 is relatively smooth, the curve with the inner panel bracket 13 has multiple small peaks, and the overall peak starting time is earlier. Among them, the small peaks at positions 1 to 7 are respectively the energy absorption deformation positions of the outer engine hood panel 11 and the expansion film 14, the force transmission guiding rib 132, the flanging surface 134 and the flap 125, the sealing strip, the front reinforcing rib 136, the headlamp 3, and the rear reinforcing rib 137. It can be seen that different structures absorb the collision energy successively during the collision, thereby reducing the injury value. The solid straight line C and the dashed straight line D are respectively the injury value curves with and without the inner panel bracket 13, where the vertical line is the head integral time domain and the horizontal line is the magnitude of the injury value; from the injury value curve, although the head injury time domain with the inner panel bracket 13 is larger, the injury value is smaller; that is, the inner panel bracket 13 plays a role in dispersing and reducing the peak value of the acceleration during the entire head collision process, thereby reducing the injury value.

[0048] In summary, the present application ensures the installation strength of the headlamp 3 and also ensures the pedestrian protection performance in the outer area of the upper front part of the vehicle. In the case of limited space between the outer engine hood panel 11 and the headlamp 3, as much as possible, the collision energy is successively absorbed before the pedestrian's head impact force is transmitted to the headlamp 3, greatly reducing the injury value of the pedestrian's head. The structure of the present application is simple, the cost is low, the constraints on the styling and layout are reduced, and it is suitable for promotion.

[0049] In a second aspect, an embodiment of the present application provides a vehicle, which includes the pedestrian protection device provided in any one of the above embodiments of the present application.

[0050] In the present application, by arranging the first energy absorption structure in the limited space between the outer engine hood panel 11 and the inner engine hood panel 12, and arranging the second energy absorption structure in the limited space between the engine compartment cover 2 and the engine hood assembly 1, when a pedestrian's head impacts the outer engine hood panel 11 of the engine hood assembly 1, the impact force is transmitted downward along the first energy absorption structure, the second energy absorption structure and the engine compartment cover 2 to in front of the headlamp 3, successively absorbing the collision energy and greatly reducing the injury value of the pedestrian's head.
