The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0031] See also Figure 1 and Figure 2 As shown, a protective plate in one embodiment of the utility model is used to be installed at the bottom of the engine housing. The protective plate includes at least two mounting parts 100 and a guide part 200 arranged between the two mounting parts 100. At least two connecting sections are formed between the two ends of the guide part 200 and the two mounting parts 100, and the two connecting sections are bent in opposite directions to form an airflow guide path between the mounting part 100 and the guide part 200 for the airflow to be transmitted toward the guide part 200.

[0032] The guide portion 200 is provided with a first guide hole group 300 and a second guide hole group 400. The first guide hole group 300 is provided in the middle of the guide portion 200. The second guide holes in the second guide hole group 400 are symmetrically provided on both sides of one side of the guide portion 200 with the first guide hole group 300 as the center line.

[0033] The first guide hole group 300 and the second guide hole group 400 are both used to guide the airflow.

[0034] It should be noted that the protective plate as a whole can be installed on the car through the installation part 100, and in actual situations, the car itself includes a frame and an engine housing. The protective plate in this embodiment can be specifically installed at the bottom of the engine housing to protect the bottom of the engine housing.

[0035] Specifically, in this embodiment, the number of the mounting portions 100 in the protective plate may be two, namely, including a first mounting sub-portion 110 and a second mounting sub-portion 120, and both ends of the air guide portion 200 are respectively connected to the first mounting sub-portion 110 and the second mounting sub-portion 120, so as to form a first connection cross section 130 and a second connection cross section 140 between the two ends of the air guide portion 200 and the first mounting sub-portion 110 and the second mounting sub-portion 120;

[0036] The bending direction of the first connecting section 130 is set so that the airflow can be directed to the guide portion 200, and the bending direction of the second connecting section 140 is used to limit the smoothness of the airflow while increasing the height of the protective plate from the ground.

[0037] That is to say, the airflow can be guided by the first connecting section 130 and the second connecting section 140, and the airflow can be guided by the first guide hole group 300 and the second guide hole group 400 provided on the guide portion 200, so as to protect the bottom of the engine casing while ensuring the heat dissipation effect of the bottom of the engine, thereby solving the problem in the prior art that the protective plate is not provided with corresponding airflow guiding holes, thereby affecting the heat dissipation effect of the bottom of the engine.

[0038] Specifically, in some preferred embodiments, the second guide hole group 400 includes a plurality of second guide holes a410 and a plurality of second guide holes b420; the plurality of second guide holes a410 are spaced apart along one side of the guide portion 200, and the plurality of second guide holes b420 are spaced apart along the other side of the guide portion 200.

[0039] It should be noted that in some preferred embodiments, the guide holes in the first guide hole group 300 and the guide holes in the second guide hole group 400 can be set to be higher in the front and lower in the back, and the airflow is guided into the upper part of the protective plate through the guide holes, thereby guiding the bottom airflow while meeting the protection of the engine oil pan.

[0040] In addition, to facilitate the installation of the protective plate, a first mounting hole 113 is provided on the first mounting sub-section 110, and a second mounting hole 123 is provided on the second mounting sub-section 120. The first mounting hole 113 and the second mounting hole 123 are both used for passing a preset fixing part so that the first mounting sub-section 110 and the second mounting sub-section 120 are fixedly connected to the vehicle frame.

[0041] In some other preferred embodiments, the first mounting hole 113 includes a first part 1131 and a second part 1132, the first part 1131 and the second part 1132 are connected to each other, and one size of the first part 1131 and the second part 1132 is larger than the other size. Specifically, the first mounting hole 113 can be arranged in a gourd shape, can be one large and one small, and the size of the first part 1131 can be larger than the size of the second part 1132. When installing the protective plate, the protective plate is horizontally translated toward the rear of the vehicle, so that the connecting part of the assembly bolt is located after the first part 1131 and moved to the second part 1132. The protective plate can be pre-installed on the bottom of the frame, and a single operator can complete the assembly without the aid of other tools, saving time and effort.

[0042] Specifically, the first mounting sub-portion 110 includes a first mounting sub-portion a111 and a first mounting sub-portion b112, which are connected to two sides of one end of the guide portion 200; wherein the first mounting sub-portion a111 and the first mounting sub-portion b112 are each provided with at least one first mounting hole 113.

[0043] Furthermore, at least part of the first mounting sub-portion a111 is bent inward to form a first reinforcement groove 1111, and the bending portion of the first reinforcement groove 1111 is provided with at least one first drain hole 1112; at least part of the first mounting sub-portion b112 is bent inward to form a second reinforcement groove 1121, and the bending portion of the second reinforcement groove 1121 is provided with at least one second drain hole 1122; the first reinforcement groove 1111 and the first drain hole 1112 are both used for drainage, and the first reinforcement groove 1111 and the first drain hole 1112 are utilized to facilitate drainage and improve the assembly surface rigidity of the first mounting sub-portion a111, and the second reinforcement groove 1121 and the second drain hole 1122 are utilized to facilitate drainage and improve the assembly surface rigidity of the first mounting sub-portion b112.

[0044] In addition, in some other embodiments, a first reinforcing rib 500 is provided between the multiple second guide holes a410 and the first guide hole group 300, and a second reinforcing rib 600 is provided between the multiple second guide holes b420 and the first guide hole group 300. It should be noted that the direction of the first reinforcing rib 500 and the second reinforcing rib 600 is consistent with the guide direction, which improves the rigidity of the protective plate and facilitates the bottom airflow guidance.

[0045] It should be noted that the protective plate shown in this embodiment can be formed in one piece with high-strength steel, and when it is installed on a car, it also has the function of reducing vehicle noise.

[0046] In summary, the protective plate in the first embodiment of the present invention has at least the following beneficial effects compared with the protective plate in the prior art:

[0047] In the protective plate provided by the utility model, at least two connecting sections are formed between the two ends of the guide part 200 in the protective plate and the two mounting parts 100, and the bending directions of the two connecting sections are opposite, so as to form an airflow guide path between the mounting part 100 and the guide part 200 for the airflow to be transmitted toward the guide part 200, and a first guide hole group 300 and a second guide hole group 400 are provided on the guide part 200, and the first guide hole group 300 and the second guide hole group 400 are both used to guide the airflow.
