[0032] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0033] Embodiment 1

[0034] This embodiment relates to a hood rear support structure, which can improve the structural strength of the rear of the engine hood; an exemplary structure thereof is as follows Figure 1 , Figure 2 and Figure 3 shown.

[0035] In general, the rear support structure of the hood includes a main support plate 3 arranged at the rear of the hood inner panel 1, and a plurality of auxiliary support plates 4. The main support plate 3 is arranged at the middle position of the hood inner panel 1 in the left-right direction, and the auxiliary support plates 4 are arranged on both sides of the main support plate 3. The main support plate 3 and the auxiliary support plates 4 together form a support for the hood outer panel.

[0036] Specifically, the main support plate 3 of this embodiment includes a main body 30 and a plurality of legs arranged on the edge of the main body 30. Each leg is bent toward the side of the hood inner plate 1 relative to the main body 30 and is fixedly connected to the hood inner plate 1; the main body 30 is abutted and connected to the hood outer plate to form a support for the hood outer plate. The main body 30 of the main support plate 3 is propped up by the legs to form a stable support surface, which can greatly increase the support area for the hood outer plate; each support plate can be fixedly connected to the hood inner plate 1 by spot welding or the like, so that the assembly and connection operation of the main support plate 3 and the hood inner plate 1 is simple and convenient.

[0037] There are of course many options for the specific shape of the main body 30; in this embodiment, Figure 2 Combined with Figure 1As shown, the main body 30 is in a long strip shape and is arranged in the left - right direction of the inner hood panel 1; the supporting feet include end supporting feet 31 respectively arranged at the left and right ends of the main body 30, and a middle supporting foot 32 arranged on one side of the main body 30; of course, in the length direction of the main body 30, the middle supporting foot 32 should be located at the middle position of the main body 30. The main body 30 adopts a long - strip structure, which is suitable for the layout space at the rear of the inner hood panel 1, and can increase the supporting distance for the outer hood panel in the left - right direction of the inner hood panel 1. Setting two end supporting feet 31 and one middle supporting foot 32 for the main body 30 can form a three - point support structure, which is beneficial to improving the structural stability of the main support plate 3.

[0038] Based on the above - mentioned setting, it is preferable to set each supporting foot to be inclined, that is, each supporting foot is inclined away from the main body 30. Each supporting foot adopts an outward - inclined form, and the supporting foot and the main body 30 together form an arch structure, which can reduce the possibility of the supporting foot being bent and deformed under force and is beneficial to improving the supporting stability of the supporting foot.

[0039] In addition, multiple first glue - applying grooves 302 are arranged at intervals on the main body 30 of this embodiment, and each first glue - applying groove 302 is arranged perpendicular to the length direction of the main body 30. At the same time, weight - reducing holes 300, positioning holes, etc. can also be arranged on the main body 30. In this embodiment, a weight - reducing hole 300 is arranged between each pair of adjacent first glue - applying grooves 302, and a flanging structure 301 is formed at the edge part of the weight - reducing hole 300; a first positioning hole 303 is also arranged at the corner of the main body 30 for positioning assistance during the assembly of the main body 30 and the outer hood panel.

[0040] By arranging multiple first glue - applying grooves 302 on the main body 30, it is convenient to apply colloids such as shock - absorbing expansion glue in the first glue - applying grooves 302 to reliably bond the outer hood panel to the main body 30. Arranging weight - reducing holes 300 on the main body 30 not only saves materials but also reduces the self - weight of the main support plate 3; by arranging a flanging structure 301 at the edge part of the weight - reducing hole 300, the structural strength of the part where the weight - reducing hole 300 is located can be effectively improved.

[0041] As Figure 3 As shown, the auxiliary support plate 4 of this embodiment is in an inverted "U" shape, and the auxiliary support plate 4 includes a middle section 40 and two end plates 41 that are翘 up relative to the middle section 40. Among them, the middle section 40 is fixedly connected to the inner hood panel 1, and both end plates 41 are in contact with the outer hood panel. Based on the above - mentioned setting, preferably, the end plates 41 are widened relative to the middle section 40, that is, the width of the end plates 41 is greater than the width of the middle section 40, and multiple second glue - applying grooves 400 are arranged at intervals on the end plates 41. At the same time, a second positioning hole 401 can also be arranged on the end plates 41 for positioning assistance during the assembly of the auxiliary support plate 4 and the outer hood panel.

[0042] The auxiliary support plate 4 adopts a "J"-shaped structure, which has the characteristics of simple and compact structure. It is not only convenient for the auxiliary support plate 4 to be flexibly arranged in the scattered space between the main support plate 3 and the hinge reinforcement plate 2, but also has good supporting performance. In the specific setting, the middle section 40 of the auxiliary support plate 4 can be fixed to the hood inner plate 1 by spot welding, and each auxiliary support plate 4 has two end plates 41, which can form a two-point support for the hood outer plate. Similar to the situation on the main body 30, the end plate 41 and the hood outer plate are also preferably fixed by bonding. By widening the end plate 41, it is convenient to arrange the second glue groove 400 on the end plate 41. In this embodiment, two second glue grooves 400 are arranged at intervals on each end plate 41, and a weight-reducing notch is arranged between the two second glue grooves 400, which can reduce the weight of the auxiliary support plate 4 while ensuring the supporting performance and bonding performance of the end plate 41.

[0043] like Figure 1 and Figure 4 As shown, the rear support structure of the hood of this embodiment also includes two hinge reinforcement plates 2 arranged at the rear of the hood inner panel 1. The two hinge reinforcement plates 2 are respectively located at the edge portions of the left and right sides of the hood inner panel 1, and the hinge reinforcement plates 2 are formed with reinforcement ribs 200 and reinforcement protrusions 21. Of course, only one of the above-mentioned reinforcement ribs 200 and reinforcement protrusions 21 can be provided, or both can be provided, or none of them can be provided. In this embodiment, an overlap flange 20 arranged in the shape of the edge of the hood inner panel 1 is formed at the edge of the hinge reinforcement plate 2, and a plurality of reinforcement ribs 200 are arranged at intervals on the overlap flange 20. A reinforcement protrusion 21 is formed on the main body of the hinge reinforcement plate 2, and the reinforcement protrusion 21 and each reinforcement rib 200 can form support for the hood outer panel.

[0044] The arrangement of the hinge reinforcement plates 2 on the left and right sides of the rear part of the hood inner panel 1 not only provides a good foundation for the installation of the hinge of the engine hood, but also the hinge reinforcement plates 2 can play a good supporting role for the edge position of the hood outer panel; by arranging reinforcing ribs 200, reinforcing protrusions 21 and other structures on the hinge reinforcement plate 2, the structural strength of the hinge reinforcement plate 2 can be improved, and these protruding structures can be used to form effective support and structural reinforcement for the hood inner panel 1.

[0045] To sum up, the rear support structure of the hood of this embodiment is equipped with multiple support plates at the rear of the hood inner panel 1, and the support plates are arranged at intervals in the left and right width directions of the hood inner panel 1, so as to form multi-point support between the hood inner panel 1 and the hood outer panel, which can have a good effect on improving the structural strength and pressure-bearing performance of the rear of the hood outer panel, and is beneficial to improving the structural strength of the rear of the engine hood.

[0046] Embodiment 2

[0047] This embodiment relates to a vehicle, on which the engine hood of the vehicle is provided with the rear support structure of the hood provided in the first embodiment.

[0048] In view of the situation where the width of the rear part of the engine hood is larger (usually the left and right width of the rear part of the hood inner panel 1 is more than 1700mm), the existing hollow area in the middle part of the hood inner panel 1 is larger, and the structures such as the reinforcing ribs are not prominent. There is also a large area at the rear with a gap between the hood outer panel and the hood outer panel, which makes it difficult to form effective support for the hood outer panel, resulting in insufficient structural strength, stiffness in the height direction, torsional stiffness, etc. of the hood outer panel. When the user presses the rear part of the hood outer panel, a pit will appear, thereby affecting the assembly accuracy of the engine hood and the user's car experience.

[0049] By adopting the rear support structure of the hood of the utility model, the rear structure of the engine hood can be effectively strengthened, so that the above-mentioned problems are well solved.

[0050] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
