[0043] The technical solution of the present invention is described in detail below in conjunction with the accompanying drawings and embodiments.

[0044] like Figure 1-Figure 3 As shown, a front hood decorative cover assembly in this embodiment includes a front hood decorative cover outer panel 1 and a front hood decorative cover inner panel 2 arranged on the lower side of the front hood decorative cover outer panel 1, and also includes a mounting component connected to the front hood decorative cover inner panel 2, the mounting component extends downward from the front hood decorative cover inner panel 2, the mounting component can be connected to the automobile water gutter 9, and after the mounting component is connected to the automobile water gutter 9, a space can be created between the front hood decorative cover inner panel 2 and the automobile water gutter 9; a weak structure is arranged on the mounting component so that after the front hood decorative outer panel is hit, the mounting component can collapse and deform.

[0045] The front hood decorative cover assembly is arranged on the vehicle to play the role of an appearance covering part. As an appearance covering part, it is necessary to ensure its appearance and certain strength. Therefore, the material of the front hood decorative cover outer plate 1 and the front hood decorative cover inner plate 2 is a composite polymer plastic material with high heat resistance, high toughness and easy to present high gloss performance, such as ABS, PC+ABS and other materials. It has high strength and high toughness mechanical properties, but too high strength will lead to adverse protection of the head of pedestrians outside the vehicle. Therefore, the installation component is set to extend downward and have a weak structure The structure of the structure enables a space to exist between the inner plate 2 of the front hood decorative cover and the automobile water gutter 9 after the front hood decorative cover assembly is assembled on the vehicle. After the vehicle hits a pedestrian and the pedestrian's head hits the front hood decorative cover assembly, the installation component can collapse and deform, so that the inner plate 2 of the front hood decorative cover can be displaced toward the automobile water gutter 9, thereby increasing the buffer space during the impact of the pedestrian's head, thereby reducing the reaction force on the pedestrian's head, reducing the damage to the pedestrian's head, and playing a role in protecting the pedestrian's head. Ultimately, while achieving lightweight, it also takes into account the pedestrian's head protection performance.

[0046] like Figure 2-Figure 3 As shown, in this embodiment, the mounting assembly includes N mounting brackets 3, such as Figure 4 and Figure 7As shown, N mounting supports 3 include mounting support bodies and mounting sleeves 33, the upper ends of the N mounting support bodies are connected to the front cover decorative cover inner plate 2, the lower ends of the mounting support bodies are connected to the upper ends of the mounting sleeves 33, and the connection between the mounting sleeves 33 and the mounting support bodies is provided with a first weakening groove 32 for reducing the connection strength between the two, wherein N≥2. In this embodiment, the N mounting support bodies are all snap-fitted to the front cover decorative cover inner plate 2; the N mounting support bodies are all provided with a first snap-fitting leg 31 and a first snap-fitting groove 34. In this embodiment, as Figure 3 , Figure 5 and Figure 8 As shown, the installation assembly also includes M positioning supports 4, the M positioning supports 4 include a positioning support body and a positioning rod 43, the upper ends of the M positioning support bodies are connected to the inner plate 2 of the front cover decorative cover, the lower end of the positioning support body is connected to the upper end of the positioning rod 43, and a second weakening groove 42 for reducing the connection strength between the positioning rod 43 and the positioning support body is provided at the connection between the positioning rod 43 and the positioning support body; the positioning rod 43 can be used to connect to the automobile water gutter 9; the M positioning support bodies are all clamped with the inner plate 2 of the front cover decorative cover; the M positioning support bodies are each provided with a second clamping foot 41 and a second clamping groove 44, wherein M≥2.

[0047] Both N and M can be 3, 4 or 5. Specifically for this embodiment, N=4, four mounting supports 3 are arranged at intervals from left to right on the rear of the front cover decorative cover inner plate 2, and M=3, three positioning supports 4 are arranged at intervals from left to right on the rear of the front cover decorative cover inner plate 2. The mounting supports 3 and positioning supports 4 are detachable, and the split design enables the mounting supports 3 and positioning supports 4 to select materials different from the front cover decorative cover outer plate 1 and the front cover decorative cover inner plate 2. The materials used for the mounting supports 3 and positioning supports 4 are plastic materials with relatively low strength and can be deformed or broken under high-speed impact, such as PP-TD20, PP-TD40, etc. The materials listed here are not limitations on the materials of the mounting supports 3 and positioning supports 4, and other plastic materials that can be deformed or broken can also be used. After the vehicle hits a pedestrian and the pedestrian's head hits the front hood decorative cover assembly, the impact energy is transmitted from the front hood decorative cover outer panel 1 and the front hood decorative cover inner panel 2 to the mounting support 3 and the positioning support 4. When the energy reaches a certain limit, due to the low material strength of the mounting support 3 and the positioning support 4, the mounting support 3 and the positioning support 4 can be deformed or brittlely fractured, and the first weakening groove 32 and the second weakening groove 42 can guide the collapse deformation, so that the mounting sleeve 33 or the positioning rod 43 is sent to peel off or fall off, which can further reduce the reaction force on the pedestrian's head and further reduce the damage to the pedestrian's head, thereby better protecting the pedestrian's head.

The ball pins 5 on the mounting support 3 are respectively inserted into the ball pin plastic mounting sleeve 11 at the corresponding position on the automobile water flow channel 9, and the positioning rods 43 of the positioning support 4 are respectively inserted into the corresponding positioning holes on the automobile water flow channel 9, so that the front cover decorative cover assembly can be preliminarily installed and positioned, which is easy to install and has a good positioning effect.

[0049] In this embodiment, Figure 3-Figure 5 As shown, the first weakened holes 211 are provided on the inner plate 2 of the front cover decoration cover corresponding to the peripheral positions of the mounting support 3 and the peripheral positions of the positioning support 4. The first weakened holes 211 can reduce the strength of the peripheral positions of the mounting support 3 and the peripheral positions of the positioning support 4, and can ensure that the peripheral positions of the mounting support 3 and the positioning support 4 can also be deformed or brittlely broken, which can further reduce the reaction force on the pedestrian's head and further reduce the damage to the pedestrian's head.
