Through performance analysis software simulation, when the hood buffer block is located at the above position, the amplitude region of the engine hood can be reduced, and the engine hood assembly mode can be improved to meet the technical standard.

[0114] Specifically, the distance between the first mounting position 101 and the second mounting position 102 in the front-rear direction of the vehicle is 227mm.

[0115] Compared with the prior art, the distance between the first mounting position 101 and the second mounting position 102 in the front-rear direction of the vehicle is 114.5 mm, and the modal is equal to 17.3 HZ; while the engine hood inner plate structure of the utility model is tested, the modal is 21.3 HZ, which significantly improves the modal of the engine hood assembly, so as to meet the technical standard, and overcomes the problem that the modal of the engine hood of the prior art automobile does not meet the technical standard.

[0116] The difference between the embodiment and the fourth embodiment is that:

[0117] The inner plate body is provided with a groove at the first mounting position 101 for the setting of the hood buffer block;

[0118] The number of the hood buffer blocks is two, and the two are symmetrically arranged about the axis of the inner plate body 100;

[0119] The material of the engine hood inner plate structure of the utility model is DC series plate.

[0120] Embodiment 6

[0121] The embodiment provides a vehicle comprising the engine hood inner plate structure of any one of the above embodiments.

[0122] Note that the above is only the preferred embodiment of the utility model and the applied technical principle. Those skilled in the art will understand that the utility model is not limited to the specific embodiments described herein, and those skilled in the art can make various obvious changes, re-adjustments and substitutions without departing from the protection scope of the utility model. Therefore, although the utility model has been described in more detail through the above embodiments, the utility model is not limited to the above embodiments, and more other equivalent embodiments can be included without departing from the utility model concept, and the scope of the utility model is determined by the appended claims.
