DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0024] Please refer to Figs. 1 to 3 A car engine compartment cover plate with stable structure, comprising a cover plate body 1 and a buffer plate 2 fixedly connected to the bottom of the cover plate body 1, and a stabilizing assembly arranged on the inner side of the cover plate body 1 for improving the stability thereof.

[0025] As Fig. 1 shown, the stabilizing assembly comprises a mounting cavity 3 arranged on the inner side of the cover plate body 1, a first reinforcing rod 4 fixedly connected to the inner side of the mounting cavity 3, and a second reinforcing rod 5 fixedly connected to the inner side of the first reinforcing rod 4.

[0026] The bottom of the buffer plate 2 is provided with a locking assembly for preventing the cover plate from being accidentally bounced up.

[0027] It should be noted that the cover plate body 1 is composed of a carbon fiber composite material layer 101 and a high-strength steel plate 102, and the high-strength steel plate 102 is arranged on the top of the carbon fiber composite material layer 101. This structure combines the lightweight and high-strength characteristics of carbon fiber composite material and the durability of high-strength steel plate, so that the cover plate body 1 is both light and strong, and can meet the requirements of strength and weight of the car engine compartment cover plate.

[0028] The left end of the first reinforcing rod 4 is fixedly connected with the inner left side wall of the mounting cavity 3, and the right end of the first reinforcing rod 4 is fixedly connected with the inner right side wall of the mounting cavity 3. The top end of the second reinforcing rod 5 is fixedly connected with the inner top wall of the mounting cavity 3, and the bottom end of the second reinforcing rod 5 is fixedly connected with the inner bottom wall of the mounting cavity 3. The number of the first reinforcing rod 4 is three, and the three first reinforcing rods 4 are arranged equidistantly along the front-rear direction of the mounting cavity 3. The number of the second reinforcing rod 5 is twenty-seven, and the number of the second reinforcing rod 5 inside each first reinforcing rod 4 is nine. Correspondingly, the nine second reinforcing rods 5 are arranged equidistantly along the left-right direction of the first reinforcing rod 4. This layout effectively improves the structural strength of the cover plate body 1, enhances the anti-deformation ability, and improves the stability of the entire engine compartment cover plate.

[0029] The buffer plate 2 is composed of a fire-retardant rubber pad 201 and two plate bodies 202, and the two plate bodies 202 are fixedly connected to the upper surface and the bottom of the fire-retardant rubber pad 201. This structure enables the buffer plate 2 to effectively absorb and disperse impact force.

[0030] The locking assembly includes a frame 6 fixedly connected to the bottom of the buffer plate 2, a connecting plate 7 fixedly connected to the inner side of the frame 6, a motor 8 fixedly connected to the left and right sides of the connecting plate 7, a threaded rod 9 fixedly connected to the output end of the motor 8, a threaded cylinder 10 threadedly connected to the outer side of the threaded rod 9, and a fixed block 11 arranged on the side opposite to the threaded cylinder 10 on the left and right sides. In use, the fixed block 11 needs to be installed inside the engine compartment. The setting of the locking assembly effectively prevents the cover plate from being accidentally bounced up.

[0031] The outer wall of the threaded cylinder 10 is square, and the height and width of the threaded cylinder 10 are equal to the height and width of the frame 6. The left and right side walls of the frame 6 are both provided with a through hole matched with the threaded cylinder 10, and the opposite side walls of the left and right fixed blocks 11 are both provided with a locking insertion hole matched with the threaded cylinder 10.

[0033] The cover plate body 1 is composed of a carbon fiber composite material layer 101 and a high-strength steel plate 102, which not only ensures the light weight, but also meets the high strength requirement, and in the mounting cavity 3 formed in the inner side of the cover plate body 1, the first reinforcing rods 4 are transversely connected to the left and right side walls of the mounting cavity 3, and the second reinforcing rods 5 are longitudinally connected to the top wall and the bottom wall of the mounting cavity 3, forming a cross support structure, and the first reinforcing rods 4 are equidistantly arranged in three in the front and rear directions of the mounting cavity 3, and the second reinforcing rods 5 are equidistantly arranged in nine in the inner side of each first reinforcing rod 4, forming a dense grid-shaped reinforcing structure, when the engine compartment cover plate is impacted by external force, the grid-shaped structure formed by the first reinforcing rods 4 and the second reinforcing rods 5 can quickly disperse the impact force to the entire cover plate body 1, avoiding deformation or damage caused by local stress concentration;

[0034] When it is necessary to fix the engine compartment cover plate, first, ensure that the fixing block 11 is correctly installed in the corresponding position inside the engine compartment, start the motor 8, the output end of the motor 8 drives the threaded rod 9 to rotate, due to the threaded connection relationship between the threaded cylinder 10 and the threaded rod 9, the threaded cylinder 10 will move along the axial direction of the threaded rod 9 under the drive of the threaded rod 9, when the threaded cylinder 10 is completely inserted into the locking socket of the fixing block 11, the locking assembly completes the locking process, if it is necessary to unlock, reverse start the motor 8, so that the threaded cylinder 10 moves reversely along the axial direction of the threaded rod 9, until it is completely withdrawn from the locking socket of the fixing block 11.
