Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] In order to solve the problem in the prior art that when a car fender is actually used, the fender will be deformed due to a collision, the overall protection capability of the fender is weak, and it cannot cope with and withstand external impact without causing a large dent, this embodiment provides the following technical solutions:

[0027] A safety protection automobile fender comprises a fixing plate 1, a second fixing strip 8 is longitudinally arranged on one side of the fixing plate 1, and the second fixing strip 8 and the fixing plate 1 are an integral structure, and a connecting piece 5 is evenly distributed longitudinally on one side of the second fixing strip 8, and the connecting piece 5 and the second fixing strip 8 are an integral structure, such as Figure 1 , Figure 2 and Figure 3As shown, the fixing plate 1 is connected to the outer shell of the vehicle through a protruding connecting piece 5, and the other side and the front and rear ends of the fixing plate 1 are provided with a first fixing bar 7 for support. The fixing plate 1 can be installed by connecting the three protruding first fixing bars 7 with the second fixing bars 8.

[0028] In this embodiment, the interior of the fixing plate 1 is composed of a protective surface layer 9, a support layer 12 and a heat insulating cotton 18. Figure 4 , Figure 5 and Figure 6 As shown, the support layer 12 is folded, the protective surface layer 9 is located at the upper end of the support layer 12, and the heat insulating cotton 18 is located at the lower end of the support layer 12. The material of the protective surface layer 9 is carbon fiber reinforced plastic. The protective surface layer 9 made of carbon fiber reinforced plastic has high tensile strength and rigidity, and has good corrosion resistance and fatigue resistance. The protective surface layer 9 is responsible for resisting daily wear and slight impact. The material of the support layer 12 is aluminum alloy. The support layer 12 made of aluminum alloy has excellent rigidity and bearing capacity, and can provide necessary support and energy absorption when the vehicle has a side collision, avoiding the impact causing the support layer 12 to bend. The material of the heat insulating cotton 18 is heat insulating cotton, and the fitting of the heat insulating cotton 18 can prevent excessive transfer of external heat to the inside.

[0029] In this embodiment, if Figure 3 and Figure 4 As shown, a heat insulation frame 6 is provided at the lower end of the exterior of the heat insulation cotton 18, and the heat insulation frame 6 can be used to wrap and restrict the heat insulation cotton 18, and the heat insulation frame 6 is fixedly connected to the inner wall of the fixing plate 1 by bolts;

[0030] In this embodiment, a plurality of upper mounting cavities 13 are sequentially arranged at the upper end of the outer portion of the support layer 12, and a plurality of lower mounting cavities 14 are sequentially arranged at the lower end of the outer portion of the support layer 12. Figure 4 and Figure 5 As shown, the upper installation cavity 13 is provided with a first reinforcing sheet 15 inside, the lower installation cavity 14 is provided with a second reinforcing sheet 16 inside, and the second reinforcing sheet 16 and the first reinforcing sheet 15 are both welded and fixed to the support layer 12. The welding connection of the first reinforcing sheet 15 and the second reinforcing sheet 16 can further assist the support layer 12, and the auxiliary support layer 12 further improves the overall impact resistance of the fixing plate 1;

[0031] In this embodiment, if Figure 6 As shown, the first reinforcing sheet 15 and the second reinforcing sheet 16 are both provided with a through cavity 19 in a transverse manner. The through cavity 19 can avoid reducing the impact resistance while reducing the overall weight of the fixing plate 1. Reducing the weight can directly reduce the overall weight of the vehicle.

Figure 4 and Figure 5 As shown, the heat insulation cotton 18 is bonded and fixed to the support layer 12 and the second reinforcement sheet 16 by the second transition layer 17. The fixing plate 1 formed by bonding can improve the impact resistance of the vehicle fender, and the impact resistance is improved while improving the overall safety during use;

On the other hand, the contact angle between the raindrops and the surface is enhanced by the protruding block 2, and the self-cleaning effect is further improved.

[0034] Working principle: When the automobile fender is used for load-bearing, the external impact is borne by the fixed plate 1, and the force is transmitted through the protective surface layer 9 and then supported by the support layer 12. The support layer 12 is further supported by the first reinforcement sheet 15 and the second reinforcement sheet 16 to prevent the support layer 12 from being deformed due to the impact, and the thermal insulation cotton 18 supported at the bottom can prevent external heat from being transferred to the inside, thereby reducing the temperature inside the car.
