[0030] like Figure 1-Figure 5 As shown, the hood sheet metal assembly includes a hood inner panel 1 and a hood outer panel 2 connected circumferentially, and also includes a support plate 3, the support plate 3 includes a panel body 31 and a plurality of support legs 32 connected to the panel body 31, the plurality of support legs 32 are connected to the same side surface of the panel body 31 and are fixedly connected to the hood inner panel 1, and the panel body 31 is fixedly connected to the hood outer panel 2.

[0031] During installation, multiple support plates 3 are arranged on the hood inner plate 1 corresponding to the positions where the hood outer plate 2 needs to be supported, and each support leg 32 of the support plate 3 is fixedly connected to the hood inner plate 1. The hood outer plate 2 is covered on the hood inner plate 1 and the support plate 3, and the support plate 3 and the hood outer plate 2 are fixedly connected. Finally, the hood outer plate 2 and the hood inner plate 1 are connected in the circumferential direction by edging.

[0032] By adopting the hood sheet metal assembly of the present invention, the hood outer panel 2 is supported by the support plate 3 independently fixed on the hood inner panel 1. The hood inner panel 1 does not need to be drawn with support protrusions, which reduces the complexity of the drawing process and has better formability. The support plate 3 is not limited by the manufacturing process, and the arrangement quantity and arrangement position between the hood inner panel 1 and the hood outer panel 2 can be freely changed as needed, which is beneficial to improving the surface rigidity of the hood sheet metal assembly.

[0033] like Figure 3 As shown, in one embodiment, the panel body 31 is rectangular, and the four support legs 32 are respectively fixed at four corners close to the panel body 31, and the angles between the four support legs 32 and the panel body 31 are equal. Figure 4 As shown, in one embodiment, the panel body 31 is trapezoidal, and one support leg 32 is fixed at each end of the shorter side, and the support leg 32 is longer, and the angle between the support leg 32 and the panel body 31 is larger, and one support leg 32 is fixed at each end and the center of the longer side, and the support leg 32 is shorter, and the angle between the support leg 32 and the panel body 31 is smaller. Figure 1 , Figure 2 In the embodiment, the upper end of the hood inner panel 1 is toward the rear end of the vehicle, and the lower end is toward the front end of the vehicle. Figure 1 , Figure 2 As shown, the support legs 32 of the support plate 3 of the panel body 31 in a trapezoidal shape are fixed to the center of the hood inner panel 1 near the front of the vehicle, the support legs 32 of the support plates 3 of the two panel bodies 31 in a rectangular shape are respectively fixed to the two sides of the hood inner panel 1 near the front of the vehicle, and the panel bodies 31 of the three support plates 3 are respectively fixedly connected to the hood outer panel 2 to support the hood outer panel 2. According to actual application conditions, the specific shape and size of the panel body 31, the specific number of the support legs 32 and the specific position connected to the panel body 31 can be adjusted, and the connection number and specific arrangement position of the support plate 3 on the hood inner panel 1 can be adjusted.

[0034] Optionally, the panel body 31 and the hood outer panel 2 are connected by adhesive bonding. Adhesive bonding can not only meet the connection strength between the panel body 31 and the hood outer panel 2, but also simplify the connection process between the two and improve assembly efficiency. In this embodiment, the panel body 31 and the hood outer panel 2 are connected by adhesive bonding using a shock-absorbing expansion adhesive 4, which expands and solidifies after baking, thereby filling the gap between the panel body 31 and the hood outer panel 2 to achieve adhesive bonding between the two.

[0035] Optionally, a receiving groove 33 is provided on a side surface of the panel body 31 facing the hood outer panel 2. The receiving groove 33 is provided, and a colloid used for gluing the panel body 31 and the hood outer panel 2 is filled in the receiving groove 33, which is conducive to limiting the position of the colloid and preventing it from overflowing, and the gluing position of the panel body 31 and the hood outer panel 2 can be preset.

[0036] like Figure 1-Figure 4 As shown, in this embodiment, the panel body 31 of each support plate 3 is provided with a strip-shaped receiving groove 33 at the circumference and the center line thereof, for placing the shock-absorbing expansion glue 4. Figure 5 As shown, the support plate 3 is fixed to the set position of the hood inner plate 1, the shock-absorbing expansion glue 4 is filled in the receiving groove 33, and the shock-absorbing expansion glue 4 can also be arranged at other positions of the panel body 31, and the hood outer plate 2 is placed on the corresponding positions of the hood inner plate 1 and the support plate 3, and the hood outer plate 2 and the support plate 3 are connected by gluing, and the hood outer plate 2 and the hood inner plate 1 are connected circumferentially by hemming, so as to complete the assembly of the hood sheet metal assembly. According to the actual application, the number of the receiving grooves 33 and the specific opening positions on the panel body 31 can be adjusted.

[0037] Optionally, the distance between the panel body 31 and the cover outer panel 2 is 3-6 mm. The distance between the two is set within this range to ensure that the shock-absorbing expansion glue 4 can fully expand and play a role in adhesive connection.

[0038] Optionally, the width of the panel body 31 on the side facing the rear of the vehicle is smaller than the width on the side facing the front of the vehicle. When a pedestrian collision occurs, the pedestrian is likely to hit the side of the hood outer panel 2 facing the rear of the vehicle. For the sake of pedestrian protection, the panel body 31 is configured as described above, so that the contact area between the side with the smaller width of the panel body 31 and the hood outer panel 2 is smaller, and the supporting force provided is smaller, so that the surface rigidity of the hood sheet metal assembly in the area that will collide with the pedestrian is weaker than that in the area where the side with the larger width of the panel body 31 is located, so that when a collision occurs, the hood outer panel 2 can produce appropriate deformation to protect the safety of pedestrians.

[0039] like Figure 1 As shown, the width of the panel body 31 of the support plate 3 located in the middle toward the rear of the vehicle is smaller than that toward the front of the vehicle, so that the panel body 31 is in an isosceles trapezoid.

[0040] Optionally, the number of the support legs 32 connected to the side of the panel body 31 facing the rear of the vehicle is less than the number of the support legs 32 connected to the side facing the front of the vehicle. When a pedestrian collision occurs, the pedestrian is likely to hit the side of the hood outer panel 2 facing the rear of the vehicle. For the protection of pedestrians, the above-mentioned arrangement of the support legs 32 makes the side of the support plate 3 connected to the support legs 32 with fewer support legs 32 provide less support to the hood outer panel 2, so that the surface rigidity of the hood sheet metal assembly in the area that will collide with pedestrians is weaker than that in the area with more support legs 32, so that when a collision occurs, the hood outer panel 2 can produce appropriate deformation to protect the safety of pedestrians.

[0041] In this embodiment, if Figure 1 , Figure 2 As shown, the support plate 3 fixed at the center line of the hood inner panel 1 has two support legs 32 connected to the side of the panel body 31 facing the rear of the vehicle, and three support legs 32 connected to the side facing the front of the vehicle, so that the support force obtained by the hood outer panel 2 covered on the hood inner panel 1 on the side of the support plate 3 facing the rear of the vehicle is smaller than the support force obtained on the side facing the front of the vehicle, and the rigidity is slightly weaker when encountering a collision. According to different vehicle models and different experimental parameters, the specific number of support legs 32 connected to the front and rear sides of the panel body 31 can be adjusted, for example, the panel body 31 has four support legs 32 connected to the side facing the front of the vehicle, and three support legs 32 connected to the side facing the rear of the vehicle.

[0042] Optionally, the number of the supporting legs 32 connected to the same end of the panel body 31 is greater than or equal to three, and the spacing between each two adjacent supporting legs 32 is equal. This arrangement is conducive to uniform force on each supporting leg 32, providing stable support for the panel body 31.

[0043] like Figure 1 As shown, the support plate 3 located in the middle has a panel body 31 with three support legs 32 connected to one end facing the front of the vehicle, and the three support legs 32 are distributed at equal intervals.

[0044] Optionally, the angle between the panel body 31 and the support leg 32 is an obtuse angle. Setting the angle between the two as an obtuse angle not only facilitates the molding process, but also ensures that sufficient support force is provided to the hood outer panel 2, so that the hood sheet metal assembly has good surface rigidity.

[0045] like Figure 1-Figure 4 As shown, the specific angles between different panel bodies 31 and the supporting legs 32 are different and can be adjusted appropriately according to design requirements.

[0046] Optionally, a positioning hole 34 is formed on the panel body 31; a positioning pin is fixed to the side of the cover outer panel 2 facing the panel body 31. With this arrangement, when the cover outer panel 2 is assembled with the cover inner panel 1 and the support plate 3, the cover outer panel 2 is accurately positioned by the cooperation of the positioning hole 34 and the positioning pin, thereby preventing position deviation when installing the cover outer panel 2.

[0047] like Figure 1-Figure 4 As shown, in this embodiment, a positioning hole 34 is respectively provided at the left and right ends of the panel body 31 of each support plate 3, and matchingly, a positioning pin is fixed at a corresponding position of the cover outer panel 2. According to actual application conditions, the number of positioning holes 34 and the specific arrangement positions on the panel body 31 can be adjusted, and accordingly, the positioning pins on the cover outer panel 2 are adjusted accordingly.

[0048] Optionally, a weight-reducing hole 35 is formed through the panel body 31. Providing the weight-reducing hole 35 is conducive to achieving lightweight production of the entire vehicle and reducing energy consumption.

[0049] like Figure 1-Figure 4 As shown, in this embodiment, two irregularly shaped weight-reducing holes 35 are formed through the panel body 31 of each support plate 3. The shape, size, number and specific opening position of the weight-reducing holes 35 on the panel body 31 can be adjusted according to actual application conditions.

[0050] Optionally, a flange 36 extends from one end of the support leg 32 away from the panel body 31, and the flange 36 is fixedly connected to the cover inner panel 1. The flange 36 is provided to increase the contact area between the support leg 32 and the cover inner panel 1, which is conducive to increasing the connection strength.

[0051] like Figure 1-Figure 4 As shown, in this embodiment, the free end of each support leg 32 extends out the flange 36, and the angle between the flange 36 and the support leg 32 can be adjusted appropriately to fit the hood inner panel 1 to be fixedly connected. In this embodiment, the flange 36 is welded to the hood inner panel 1.

[0052] Optionally, the number of the support plates 3 is greater than or equal to three, and the plurality of support plates 3 are evenly spaced along the width direction of the cover. This arrangement allows the plurality of support plates 3 to be as evenly stressed as possible, ensuring stable support for the cover outer panel 2.

[0053] like Figure 1 As shown, in this embodiment, three support plates 3 are provided, along the width direction of the cover, that is, along Figure 1The support plates 3 are arranged continuously in the left-right direction, and the distance between every two adjacent support plates 3 is equal.

[0054] The present invention also provides a vehicle, comprising the hood sheet metal assembly described in any one of the above embodiments.

[0055] In the vehicle of the present invention, the support plate 3 independently fixed on the hood inner panel 1 is used to support the hood outer panel 2. The hood inner panel 1 does not need to be drawn with support protrusions, which reduces the complexity of the drawing process and has better formability. In addition, the support plate 3 is not limited by the manufacturing process, and the arrangement quantity and arrangement position between the hood inner panel 1 and the hood outer panel 2 can be freely changed as needed, which is beneficial to improving the surface rigidity of the hood sheet metal assembly.

[0056] As needed, the above technical solutions can be combined to achieve the best technical effect.

[0057] The above are only the principles and preferred embodiments of the present invention. It should be noted that, for those skilled in the art, several other modifications can be made based on the principles of the present invention, which should also be considered as the protection scope of the present invention.
