Obviously, the described embodiments are only part of the embodiments of the present application, and are not an exhaustive list of all the embodiments. It should be noted that the embodiments and features in the embodiments of the present application can be combined with each other unless they conflict.
[0027] Example 1
[0028] This embodiment provides a hood hinge bracket structure, which is connected to the hood outer panel 11. The hood hinge bracket reinforcement structure serves to increase the connection strength between the hinge bracket 2 and the hinge 3, thereby improving the stability of the hinge 3 in opening and closing the hood.

[0030] like Figures 1-4 As shown, the hood hinge bracket reinforcement structure includes a hood support plate 1, at least one hinge bracket 2 arranged on the top of the hood support plate 1, and a hinge 3 arranged at the bottom of the hood support plate 1 and connected to the hinge bracket 2; a first reinforcement portion 21 is provided on the hinge bracket 2, and a second reinforcement portion 31 is provided on the hinge 3. The first reinforcement portion 21 and the second reinforcement portion 31 are arranged corresponding to each other and form a reinforcement inner cavity 4 between the first reinforcement portion 21 and the hood support plate 1 respectively, and the reinforcement inner cavity 4 is located on the side of the connection point 41 of the hinge 3 and the hinge bracket 2.
[0031] The first reinforcement portion 21 is configured to protrude outward from the hinge bracket 2, and the second reinforcement portion 31 is configured to protrude outward from the hinge 3. The first and second reinforcement portions 21, 31 are configured to protrude in opposite directions from the sides of the cover support plate 1. The reinforced inner cavity 4 formed between the first and second reinforcement portions 21, 31 effectively increases the rigidity of the first and second reinforcement portions 21, 31 at their respective locations on the cover support plate 1, thereby enhancing the connection strength between the hinge bracket 2 and the hinge 3 on the cover support plate 1.
[0032] The hood support plate 1 is connected to the hood outer panel 11. The hood support plate 1 and the hood outer panel 11 can be connected by welding, screwing, etc. In this embodiment, the circumferential edge of the hood support plate 1 and the circumferential edge of the hood outer panel 11 are connected by edge crimping.
[0033] Example 2
[0034] This embodiment optimizes a hinge bracket structure of a cover based on the above embodiment, and in particular provides a specific implementation method of the hinge bracket:
[0035] One end of the hinge bracket 2 is connected to the hood support plate 1, and the other end of the hinge bracket 2 is connected to the hood outer panel 11. The hinge bracket 2 passes through the hood support plate 1 and is connected to the hinge 3 through a number of mounting parts 33, which plays a role in strengthening the connection strength of the hinge 3; at the same time, the hinge bracket 2 is supported and cooperated with the hood outer panel 11, and is crushed and deformed when subjected to collision force, which has a certain energy absorption effect.

[0037] like Figures 1-4 As shown, the hinge bracket 2 includes a bracket body 22 and a support portion 23 connected to the side of the bracket body 22; the bracket body 22 and the support portion 23 are connected to form an angle, and the bracket body 22 and the support portion 23 can be integrally connected or welded. In this embodiment, the bracket body 22 and the support portion 23 are integrally connected to form an L-shaped structure.
[0038] The connection between the bracket body 22 and the support portion 23 is a transitional arc region, which abuts against the cover support plate 1. The bracket body 22 has a flat bottom surface, which abuts against the cover support plate 1. A plurality of first connecting portions 231 are provided on the support portion 23, and a plurality of second connecting portions 221 are provided on the side of the bracket body 22. The plurality of first connecting portions 231 are recessed relative to the support portion 23 and abut against the cover support plate 1. The plurality of second connecting portions 221 abut against the cover support plate 1. The first connecting portions 231 and the second connecting portions 221 are respectively connected to the cover support plate 1. In this embodiment, the first connecting portions 231 and the second connecting portions 221 are respectively welded to the cover support plate 1. The bracket body 22 of the hinge bracket 2 abuts against the cover support plate 1, and the connection relationship is stable.
[0039] The connection between the bracket body 22 and the second connection parts 221 is provided with an arc edge 222, which is positioned and matched with the cover support plate 1, so that the second connection parts 221 are stably attached to the cover support plate 1, further improving the welding effect of the second connection parts 221.
[0040] The bracket body 22 is provided with a plurality of first fixing holes 223. The hinge 3 includes a fixing portion 32, which is provided with a plurality of second fixing holes (not labeled in the figure). The first fixing holes 223 and the second fixing holes are arranged in an aligned manner. A mounting member 33 extends through the first fixing holes 223 and the second fixing holes to connect to the hood support plate 1, thereby securing the bracket body 22 and the fixing portion 32 to the hood support plate 1. In this embodiment, the mounting member 33 is a bolt and nut assembly. This provides a high connection strength between the bracket body 22, the hood support plate 1, and the hinge 3, improving the opening and closing stability of the hinge 3.
[0041] At least one positioning hole 211 is provided in the first reinforcement portion 21 . The positioning hole 211 is positioned using an auxiliary tool to facilitate determination of the position of the bracket body 22 , which is beneficial for rapid assembly of the bracket body 22 .
[0042] The support portion 23 is provided with at least one weight-reducing hole 232 to reduce its weight, enabling it to absorb energy through crushing deformation. A bent portion 233 is provided at the end of the support portion 23. The bent portion 233, the support portion 23, and the bracket body 22 form a roughly Z-shaped structure. The bent portion 233 abuts against the hood outer panel 11, specifically, the bent portion 233 is bonded to the hood outer panel 11. The bent portion 233 has a raised portion 234 to enhance the strength of the position where it supports the hood outer panel 11.
