[0031] In addition, the terms "first" and "second" are only for descriptive purposes and cannot be understood as indicating or implying relative importance or implying the number of technical features indicated. Therefore, the features defined with "first" and "second" can explicitly or implicitly include at least one of the features.

[0032] In the description of the present disclosure, the meaning of "a plurality of" is at least two, such as two, three or more, etc., unless otherwise explicitly specified.

[0033] From Figure 1 As can be seen, the engine under shield 1 of the present application has a first surface 12, a second surface 13, a first end 11 and a second end 14, wherein the first surface 12 is opposite to the second surface 13, the first end 11 is opposite to the second end 14, and the engine assembly is installed on the first surface 12 of the under shield 1.

[0034] Specifically, the under shield 1 is provided with a frame mounting portion 18, a cooling module mounting space 15 and a pedestrian calf protection device mounting rack 2, and the under shield 1 is mounted on the frame through the frame mounting portion 18. The frame mounting portion 18 can be provided at the second end 14 of the under shield 1 as in the embodiment, or can be provided at other parts of the under shield 1, as long as it can be mounted on the frame. Figure 1

[0035] Further, as shown in the drawings, the under shield 1 is also provided with a plurality of through holes 19, and the through holes 19 are arranged on the first surface 12 of the under shield 1. Figure 1 ​The bottom guard plate 1 is shown to have various shapes such as circles and irregular shapes.

[0038] The first protruding strip 3 separates the cooling module mounting space 15 from the pedestrian lower leg protection device mounting bracket 2, from Figure 1 As can be seen, there is a height difference between the cooling module installation space 15 and the pedestrian lower leg protection device mounting bracket 2, so that the installation of the pedestrian lower leg protection device and the engine cooling module has a height difference, thereby isolating the pedestrian lower leg protection device and the engine cooling module from each other. In this way, the pedestrian lower leg protection device and the engine cooling module can be installed on the same bottom guard plate 1, and each has its own isolated and independent installation space to prevent mutual interference.

[0039] In other alternative embodiments, the isolation between the pedestrian lower leg protection device mounting bracket 2 and the cooling module mounting space 15 can also be achieved by a partition or the like, as long as it can separate the pedestrian lower leg protection device from the engine cooling module.

[0040] The following section will describe in detail, with reference to the accompanying drawings, the pedestrian lower leg protection device mounting bracket 2 and the cooling module mounting space 15.

[0041] Figure 2 The present invention shows a pedestrian lower leg protection device mounting bracket 2 for an engine underbody guard plate 1. The pedestrian lower leg protection device is mounted on the top surface of the pedestrian lower leg protection device mounting bracket 2.

[0053] The cross section of the boss 5 in the form of a right-angled trapezoid makes the cooling module mounting space 15 more compact, so as not to interfere with the installation of other parts of the engine. In alternative embodiments, the cross section of the boss 5 can also be, but is not limited to, a rectangle, etc.

[0054] As shown in the figure, the boss 5 and the first protrusion 3 are provided with a ventilation groove 4, and the ventilation groove 4 is provided with a support plate 41 and a support seat 42, and the two ends of the support plate 41 and the support seat 42 are connected with the boss 5 and the first protrusion 3 respectively.

Figure 4 Figure 4 The cooling module mounting space 15 is divided into an intercooler mounting portion 16 and a water tank mounting portion 17 by the protruding portion 52 and the protruding position 57 of the side edge 44. The first protrusion 3 to the protruding position 57 of the side edge 44 is the intercooler mounting portion 16, and the protruding position 57 to the second protrusion 51 is the water tank mounting portion 17. The intercooler mounting portion 16 and the water tank mounting portion 17 are respectively used for mounting the intercooler and the water tank of the cooling module of the engine.

[0056] Optionally, the side edge 44 of the support seat 42 and the protruding portion 52 of the boss 5 are both provided with a second mounting hole 56, and the second mounting hole 56 is used for mounting the water tank.

[0057] Optionally, the side edge 44 of the support seat 42 and the protruding portion 52 of the boss 5 are both provided with a second mounting hole 56, and the second mounting hole 56 is used for mounting the water tank.

[0058] ​When the engine is installed, one end edge of the intercooler abuts against the first protrusion 3 and is isolated by the pedestrian calf protection device on the first protrusion 3.

[0059] The water tank is installed on the side edge 44 of the support base 42 and the top surface of the protruding part 52 of the boss 5, and the edge of the water tank abuts against the second protrusion 51, isolating the water tank from other parts of the engine and preventing the hot air generated by the intercooler from flowing back through the sealing strip arranged on the second protrusion 51.

[0060] In other embodiments, the positions of the intercooler mounting part 16 and the water tank mounting part 17 can be set according to the specific arrangement of the cooling module of the engine.
