[0020] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0021] This utility model discloses a hood outer panel support reinforcement structure.

[0022] According to the appendix Figure 1-2 As shown, it includes:

[0023] The reinforcing plate 1 has an outer hood panel 2 and an inner hood panel 3 on its top and bottom, respectively. The reinforcing plate 1 is composed of an integrally formed reinforcing main plate 11, a support leg 12 and a mounting plate 13. The support leg 12 and the mounting plate 13 are respectively set on the top and bottom of the reinforcing main plate 11. The upper surface of the support leg 12 is coated with vibration damping adhesive 121, and the vibration damping adhesive 121 fills the gap between the upper surface of the support leg 12 and the outer hood panel 2 through coating and baking. The mounting plate 13 is welded to the inner hood panel 3.

[0024] The one-piece molding design of the reinforcing plate 1 significantly improves the rigidity and stability of the hood, effectively solving the problems of dents and abnormal noises caused by insufficient rigidity. By applying vibration damping adhesive 121 to the upper surface of the support leg 12 and using a coating and baking process to fill the gap between the support leg 12 and the outer hood plate 2, the transmission of vibration and noise is effectively reduced, improving support stability. The mounting plate 13 is fixed to the inner hood plate 3 by welding, which enhances the welding strength and structural stability, while simplifying the installation and adjustment process and improving production efficiency.

[0025] Furthermore, vibration damping adhesive 121 is specifically a thermosetting solvent-free metal-to-metal reactive adhesive based on epoxy resin.

[0026] Furthermore, the motherboard 11 is tilted and reinforced with ribs on the outside.

[0027] Furthermore, a clamping plate 131 is provided on the side of the mounting plate 13 away from the reinforcing main board 11, extending outward.

[0028] Furthermore, multiple weld points 132 are formed by welding between the mounting plate 13 and the inner bottom wall of the hood inner plate 3, and between the end of the clamping plate 131 and the inner side wall of the hood inner plate 3.

[0029] Furthermore, a pin 133 is provided between the mounting plate 13 and the inner bottom wall of the hood inner plate 3.

[0030] Furthermore, the outer edge of the outer hood panel 2 is provided with a edging 21, and the outer edge of the inner hood panel 3 is bent upward and closely fitted to the inner wall of the edging 21.

[0031] The hood outer panel support reinforcement structure achieves its support and reinforcement functions through the reinforcing plate 1. The reinforcing plate 1 is integrally formed from the reinforcing main plate 11, support legs 12, and mounting plate 13; this design ensures the integrity and stability of the structure. The reinforcing main plate 11 is angled to adapt to the curved shape of the hood and its rigidity is enhanced by reinforcing ribs. The upper surface of the support legs 12 is coated with vibration-damping adhesive 121. During the coating and baking process, the vibration-damping adhesive 121 melts and fills the gap between the support legs 12 and the hood outer panel 2, forming an effective vibration-damping layer that reduces the transmission of vibration and noise.

[0032] Mounting plate 13 is fixed to the inner hood panel 3 by welding. Multiple weld points 132 are formed during the welding process, which enhances the welding strength and structural stability. The clamping plate 131 further expands the welding area and improves the connection strength. In addition, the pin 133 serves as an auxiliary connector, improving the connection strength and durability between mounting plate 13 and inner hood panel 3.

[0033] The outer edge of the outer hood panel 2 is provided with a edging 21, and the outer edge of the inner hood panel 3 is bent upward and closely fitted with the inner wall of the edging 21, forming a good seal and connection, which further enhances the overall rigidity and stability of the hood.

[0034] The reinforcing plate 1 can be made of high-strength steel plate or aluminum alloy to improve its rigidity and lightweight performance. The vibration damping adhesive 121 is a thermosetting solvent-free metal-to-metal reactive adhesive based on epoxy resin, which has good vibration damping and bonding properties.

[0035] The reinforcing plate 1 is integrally formed by stamping, creating a unified structure comprising the reinforcing main plate 11, support leg 12, and mounting plate 13. Vibration damping adhesive 121 is applied to the upper surface of the support leg 12 and cured through a baking process, filling the gap between the support leg 12 and the outer hood panel 2. The mounting plate 13 is welded to the inner hood panel 3, forming multiple weld points 132 during the welding process. A pin 133 is installed between the mounting plate 13 and the inner bottom wall of the inner hood panel 3.

[0036] Install the reinforcing plate 1 between the outer hood panel 2 and the inner hood panel 3, ensuring that the support leg 12 fits tightly against the outer hood panel 2, and weld the mounting plate 13 firmly to the inner hood panel 3. After installation, perform necessary adjustments and tests to ensure that the rigidity and stability of the hood meet the design requirements.
