[0042] With the continuous development of automobile technology and individual needs, people's demand for automobile modeling is also more and more diversified and personalized, which directly promotes the continuous progress of automobile modeling. Among them, the engine cover, as one of the important parts of the automobile modeling, is also constantly improving. At present, the cladding type cover is more and more accepted by people because of its large coverage and hidden seam line. However, a remarkable feature of the cladding type cover is the widening of the side, which means that the cladding type cover covers part of the area of the traditional fender, and thus expands the installation space of the engine cover hinge. Although this change improves the appearance, it also brings new challenges: due to the insufficient structural strength of the newly added installation area, the engine cover is prone to deformation or fracture.

[0043] After careful research by the applicant, it is found that the newly added area not only has lower rigidity, but also is a place where users are prone to lean. When subjected to external forces, such as human leaning, the outer panel of the hood may appear irreversible collapse or concave deformation, which has a negative impact on the overall quality of the hood. In addition, the length of the traditional hinge reinforcing plate is limited, and during the process of opening the hood, the front end becomes the part that bears the most force, which increases the risk of breaking the hood.

[0044] The main purpose of the present application is to provide a hinge reinforcing plate and an engine cover to solve the problem of how to improve the structural strength of the hinge mounting area of the engine cover to avoid deformation or breakage of the engine cover.

[0048] Please refer to Figure 1 and Figure 2 In an embodiment, the flat plate 11 is protruded in a direction away from the fixing groove 14 to form a first connecting seat 111, and the first connecting seat 111 is used for fixed connection with a second connecting seat (not shown in the figure) on the inner plate 210;Specifically, since the flat plate 11 and the inner plate 210 cannot be completely attached, the first connecting seat 111 is formed on the flat plate 11 in a direction away from the fixing groove 14, and the second connecting seat is formed on the inner plate 210 in a direction towards the hinge reinforcing plate 100, effectively solving the attachment problem between the two, and the fixed connection of the first connecting seat 111 and the second connecting seat ensures that the flat plate 11 and the inner plate 210 can be firmly combined, provides stable mechanical support, enhances the reliability of the overall structure, and since the first connecting seat 111 and the second connecting seat are fixedly connected, there is a certain gap between the flat plate 11 and the inner plate 210, which provides a convenient condition for later rust-proof treatment between the two, effectively preventing the problem of rusting of metal parts due to dampness or oxidation, thereby prolonging the service life of the engine cover 200. In the embodiment, the first connecting seat 111 and the second connecting seat are welded and fixed, and in other embodiments, the first connecting seat 111 and the second connecting seat can also be connected and fixed by bolts 4, and the embodiment does not limit this. The number of the first connecting seat 111 and the second connecting seat can be selected according to actual installation requirements, and the embodiment does not limit this.

Through the threaded cooperation of the bolt 4 and the nut, the connection between the hinge reinforcing plate 100, the inner plate 210 and the hinge can be more firm and reliable. This mechanical connection method can withstand large tensile and shear forces, greatly enhancing the stability of the overall structure of the engine cover 200, and the bolt 4 connection can remain stable in the face of complex working conditions such as vibration and impact, ensuring reliability during long-term use. It also makes disassembly and reinstallation simple and fast. When the engine cover 200 or its internal components need to be repaired, inspected or replaced, the engine cover 200 can be easily disassembled and assembled with simple tools, improving maintenance efficiency.

[0050] Please refer to Figure 1 and Figure 2 In an embodiment, the positioning hole 112 is arranged on the flat plate 11, and the positioning hole 112 is used for the positioning column (not shown in the figure) on the inner plate 210 to pass through; and / or, the weight-reducing hole 113 is arranged on the flat plate 11; Specifically, the positioning hole 112 arranged on the flat plate 11 is used for the positioning column on the inner plate 210 to pass through, ensuring that each component can be accurately aligned during assembly. This precise positioning reduces installation errors and ensures that each component is correctly installed in place, thereby improving overall assembly quality. The use of the positioning hole 112 and the positioning column simplifies the installation steps, allowing workers to quickly complete preliminary positioning without the need for additional tools, improving production efficiency.

In other embodiments, the number of positioning holes 112 can be selected according to actual installation needs, which is not limited in the present embodiment. Arranging the weight-reducing hole 113 on the flat plate 11 can significantly reduce the weight of the hinge reinforcing plate 100 without affecting the structural strength of the hinge reinforcing plate 100. This not only helps to reduce the overall weight of the engine cover 200, but also improves the fuel economy and handling performance of the vehicle, in line with the design trend of modern automobile lightweighting. It also reduces the amount of material used, directly reducing manufacturing costs. For mass production, this design can effectively control costs without sacrificing product quality.

[0051] Please refer to Figure 2 and Figure 4In an embodiment, the connecting claw 3 comprises a first plate 31, a second plate 32 and a third plate 33, the first plate 31 is connected with the first vertical wall 12, the first plate 31 and the third plate 33 are both connected with the second plate 32, the third plate 33 is used for connecting with the outer plate 220, the second plate 32 and the flat plate 11 form a first angle A, 110°≤A≤120°; the first vertical wall 12 and the flat plate 11 form a second angle B, 95°≤B≤105°; and / or, the second vertical wall 13 and the flat plate 11 form a third angle C, 95°≤C≤105°; specifically, the first angle between the second plate 32 and the flat plate 11 is A, the second angle between the first vertical wall 12 and the flat plate 11 is B and the third angle between the second vertical wall 13 and the flat plate 11 is C, so that the second plate 32 and the flat plate 11 are arranged in an inclined manner, the first vertical wall 12 and the second vertical wall 13 and the flat plate 11 are all arranged in an inclined manner, the design of such an inclined angle can ensure the structural strength while providing better support effect, especially when facing external pressure or collision, such an angle design helps to evenly distribute the force to the entire hinge reinforcing plate 100, rather than concentrating on a certain point, thereby improving the overall pressure resistance, prolonging the service life of the hinge reinforcing plate 100, reducing the damage risk of the engine cover 200 during use, and more conducive to deformation of the hinge reinforcing plate 100 in the event of a safety accident, thereby reducing the harm to pedestrians.

[0052] Please refer to Figure 1 and Figure 5 In an embodiment, the connecting claw 3 further comprises a connecting adhesive layer (not shown in the figure), the third plate 33 away from the flat plate 11 is provided with a groove 331 accommodating the connecting adhesive layer, the connecting adhesive layer is used for connecting with the groove wall of the groove 331, and the connecting adhesive layer is used for connecting with the outer plate 220; specifically, the groove 331 is used for accommodating the connecting adhesive layer, effectively preventing the connecting adhesive layer from being displaced during the coating and curing process, ensuring that the connecting adhesive layer only plays a role at the predetermined position, and also simplifying the coating process of the connecting adhesive layer, the user only needs to fill the connecting adhesive layer into the groove 331, without worrying about the problem of overflow or uneven distribution of the connecting adhesive layer, and the fixed position of the connecting adhesive layer in the groove 331 also facilitates the rapid alignment of the third plate 33 and the outer plate 220, improves the assembly efficiency and reduces the assembly difficulty.

[0053] In an embodiment, the height of the first vertical wall 12 is tapered in the first direction away from the hinge; and / or, the height of the second vertical wall 13 is tapered in the first direction away from the hinge; in particular, the first direction is the front-rear direction, and the height of the first vertical wall 12 and the height of the second vertical wall 13 are both tapered from the rear to the front, so that the rear end of the first vertical wall 12 and the rear end of the second vertical wall 13 are the strongest, and the front end is less strong, and thus more easily deformed. In particular, when the engine cover 200 collides with a pedestrian in the event of a safety accident, the front end of the engine cover 200 deforms first, and when the impact force is too large, the degree of deformation of the engine cover 200 increases. Because the front end of the hinge reinforcement plate 100 is easily deformed, the overall engine cover 200 is more easily deformed, which can avoid the problem of increasing the injury to the pedestrian due to the excessive structural strength and rigidity of the engine cover 200. Thus, through the structure of the hinge reinforcement plate 100 that is easily deformed at the front end, the injury to the pedestrian can be reduced, especially when the head of the pedestrian collides with the engine cover 200. Through the structure of the hinge reinforcement plate 100, the degree of injury to the pedestrian can be effectively reduced, and the danger to the pedestrian can be reduced, which embodies the scientific nature and practicality of the design.

[0054] Please refer to Figure 1 In an embodiment, the length of the flat plate 11 is L, and 355mm≤L≤385mm; and / or, the width of the flat plate 11 is H, and 30mm≤H≤40mm; and / or, the support frame 1 is integrally formed. In particular, in this embodiment, the length L of the flat plate 11 is 370mm, and the width H of the flat plate 11 is 35mm. The length requirement and the width requirement of the flat plate 11 make the hinge reinforcement plate 100 form an elongated strip structure as a whole. The length requirement of the flat plate 11 ensures that the flat plate 11 can cover a sufficient area and provide effective support. Compared with a conventional hinge reinforcement plate 100 that is shorter, the hinge reinforcement plate 100 can move the front stress point forward, effectively disperse the pressure of the front stress point when the engine cover 200 is opened, reduce the risk of fracture of the engine cover 200 in this area, and improve the safety and reliability of the entire engine cover 200. At the same time, the hinge reinforcement plate 100 does not increase unnecessary weight or complexity due to being too long, so that the engine cover 200 can maintain good operational flexibility. The width requirement of the flat plate 11 provides sufficient lateral support and enhances the rigidity of the overall structure, avoiding deformation or instability due to insufficient width. The support frame 1 manufactured by the integral forming process not only reduces the number of welding points or joints, reduces potential weak links, and improves the strength and durability of the overall structure, but also simplifies the production process, reduces the assembly steps, improves the production efficiency, and ensures the quality consistency of the product.

[0055] According to the embodiment of the utility model, the first vertical wall 12 and the second vertical wall 13 are welded or connected with the flat plate 11 through bolts 4, so that the support frame 1 is in the overall structure of a n shape, and additional rigidity and stability are provided for the engine cover 200.

[0056] Please refer to Figures 5 to 7 The utility model also provides an engine cover 200, which comprises an inner plate 210, an outer plate 220, a hinge and the hinge reinforcing plate 100, and the specific structure of the hinge reinforcing plate 100 is referred to the above-mentioned embodiments.

The outer plate 220 is connected with the inner plate 210, and a cavity 230 is formed between the outer plate 220 and the inner plate 210. The hinge reinforcing plate 100 is located in the cavity 230. The inner plate 210 is provided with a containing groove 2101 which is in communication with the cavity 230. The containing groove 2101 is used for containing the support frame 1. The groove wall of the containing groove 2101 is protruded towards the hinge reinforcing plate 100 to form a second connecting seat. The groove wall of the containing groove 2101 is also provided with a second through hole and a positioning column. The hinge is located on the side of the inner plate 210 which is away from the hinge reinforcing plate 100. Specifically, the inner plate 210 is arranged close to the engine compartment. The outer plate 220 is arranged away from the engine compartment. The hinge reinforcing plate 100 is accurately arranged in the cavity 230 formed by the outer plate 220 and the inner plate 210, so as to ensure that the hinge reinforcing plate 100 can effectively support the inner plate 210 and the outer plate 220 and disperse external pressure, reduce local stress concentration, improve the compression resistance, enhance the overall strength and durability of the engine cover 200, and the inner plate 210 is provided with the containing groove 2101 which is in communication with the cavity 230 and is used for containing the support frame 1. This design ensures the stable installation of the support frame 1 and reduces unnecessary space occupation. The hinge is located on the side of the inner plate 210 which is away from the hinge reinforcing plate 100. This design enables the hinge to operate smoothly when the engine cover 200 is opened and closed, avoids the direct contact between the hinge and the hinge reinforcing plate 100, reduces friction and wear, and prolongs the service life.
