[0002] Currently, vehicle body designs often incorporate panels made of various types of noise-reducing materials (such as interior cabin floors) to reduce interior noise and enhance ride comfort. Related technologies employ liquid damping materials sprayed uniformly onto interior floors for sound insulation and noise reduction. However, this approach suffers from the following drawbacks: Due to the low density of liquid damping materials, thin films offer limited vibration and noise reduction effectiveness in areas of the vehicle body panel where vibration energy is concentrated. Thick films, on the other hand, require large quantities and are expensive. Utility Model Content

Preferably, the panel 1 is an electrophoretic steel plate.

[0030] The first damping layer 2 includes a first damping body and a plurality of first annular grooves recessed on the first damping body, and each of the first annular grooves is provided with a first protrusion; it can be understood that the first protrusion and the first damping body are integrally formed parts, and the shape of the first damping layer 2 is set according to the shape of the first surface of the panel 1; the number of the first annular grooves is equal to the number of the first annular protrusions 11, and the number of the first accommodating grooves 12 is equal to the number of the first protrusions.

[0032] In the present invention, a plurality of first annular protrusions 11 are arranged at intervals on the first surface of the panel 1, and each of the first annular protrusions 11 forms a first receiving groove 12; the first damping layer 2 includes a first damping body and a plurality of first annular grooves recessed on the first damping body, and each of the first annular grooves is provided with a first protrusion; each of the first annular protrusions 11 is installed in each of the first annular grooves in a one-to-one correspondence, and each of the first protrusions is installed in each of the first receiving grooves 12 in a one-to-one correspondence, and the first damping body is bonded to the first surface; the first damping layer 2 is bonded to the first surface of the panel 1, so that the vehicle body panel structure integrates the characteristics of the panel 1 material and the damping material, thereby enhancing the vibration isolation and noise reduction characteristics of the vehicle body panel structure; and the first annular protrusions 11 are equivalent to the rib structure on the panel 1, thereby enhancing the strength and rigidity of the vehicle body panel structure. Furthermore, the first annular protrusion 11 of the panel 1 is embedded in the first annular groove of the first damping layer 2, and the first protrusion of the first damping layer 2 is embedded in the first receiving groove 12 of the panel 1. The design of the first annular protrusion 11 enhances the adhesion of the first damping layer 2 to the first surface of the panel 1, thereby enhancing the stability of the vehicle body panel structure in the normal direction (i.e., perpendicular to the first surface). Furthermore, the design of the first annular protrusion 11 can reduce the amount of the first damping layer 2 used, thereby reducing the manufacturing cost of the vehicle body panel structure.

[0033] In one embodiment, if Figure 1 As shown, the thickness d1 of the first damping body at the corresponding position of the first annular groove is 2 mm to 3 mm (for example, 2 mm, 2.5 mm, 3 mm, etc.); that is, the distance between the bottom surface of the first damping body and the first annular protrusion 11 is 2 mm to 3 mm; that is, the thickness of the first damping layer 2 above the first annular protrusion 11 is 2 mm to 3 mm. It should be noted that the thickness of the first damping layer 2 above the first annular protrusion 11 is the smallest.

[0034] In one embodiment, if Figure 1 As shown, the vehicle body panel structure further includes a second damping layer 3 bonded to the second surface of the panel 1. The first surface and the second surface are disposed opposite each other; that is, the first surface and the second surface are respectively opposite surfaces of the panel 1. It can be understood that the first surface is the upper surface of the panel 1, and the second surface is the lower surface of the panel 1. Thus, the first damping layer 2 is provided on the upper surface of the panel 1, and the second damping layer 3 is provided on the lower surface of the panel 1. Consequently, damping layers are provided on both the upper and lower surfaces of the panel 1, further enhancing the vibration damping and noise reduction properties of the vehicle body panel structure.

[0035] In one embodiment, if Figures 1 to 6 As shown, a second annular groove is provided on the second surface of the panel 1 at a corresponding position to each of the first annular protrusions 11; a second protrusion is provided in each of the second annular grooves; it can be understood that the second annular groove is arranged at the bottom of the first annular protrusion 11, and the second protrusion is arranged at the bottom of the first accommodating groove 12.

[0036] The second damping layer 3 includes a second damping body and a plurality of second annular protrusions protruding from the second damping body, each of the second annular protrusions forming a second accommodating groove; it can be understood that the second annular protrusion and the second damping body are an integrally formed part; the shape of the second damping layer 3 is designed to be consistent with the shape of the second surface of the panel 1.

That is, the distance between the bottom surface of the second damping layer 3 and the second protrusion is 2 mm to 4 mm, and the thickness of the second damping layer 3 below the second protrusion is 2 mm to 4 mm. It should be noted that the thickness of the second damping layer 3 below the second protrusion is the smallest.

It can be understood that the upper and lower surfaces of the vehicle body panel structure are both flat, thereby ensuring the flatness of the vehicle interior floor and improving the applicability of the vehicle body panel 1 structure. It should be noted that for high-vibration areas of the vehicle floor, the selected vehicle body panel structure is equipped with the first damping layer 2 and the second damping layer 3; for normal vibration areas of the vehicle floor, the selected vehicle body panel structure is equipped with only the first damping layer 2. This ensures the vehicle floor has excellent noise reduction properties while also reducing the use of damping materials and lowering the vehicle's manufacturing costs.

In this embodiment, the first annular protrusion 11 has a sufficient height and the panel 1 has a sufficient thickness to ensure the structural strength and rigidity of the vehicle body panel.

In this embodiment, the panel 1 has sufficient thickness to ensure the structural strength and rigidity of the vehicle body panel.
