[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: an automobile roof panel, comprising an upper base plate and a lower base plate, a support plate disposed between the upper base plate and the lower base plate, a slot being formed inside the support plate, a honeycomb panel frame being disposed within the slot, a first connecting plate and a second connecting plate being disposed at the top and bottom of the support plate respectively, a first connecting groove and a second connecting groove being formed on the upper base plate and the lower base plate respectively, the outer sides of the upper base plate and the lower base plate being slidably connected by a first outer frame and a second outer frame, a first damping block being disposed inside the first outer frame and the second outer frame, and a second damping block being disposed on the outer sides of the upper base plate and the lower base plate, which cooperates with the first damping block.

[0006] By adopting the above technical solution, the ceiling panel is provided with an upper base plate, a support plate, and a lower base plate from top to bottom. The support plate has a slot, and a honeycomb panel frame is installed in the slot. The honeycomb panel frame, together with the upper and lower base plates, enables the ceiling panel to resist forces from multiple directions, improving the stability of the overall structure. The top and bottom of the support plate are respectively provided with a first connecting plate and a second connecting plate, which are connected to the first and second connecting slots opened on the upper and lower base plates, respectively. The outer sides of the upper and lower base plates are slidably provided with a first outer frame and a second outer frame. The first damping block is provided in the first and second outer frames, which cooperates with the second damping block provided on the outer side of the upper and lower base plates to achieve a vibration-damping effect.

[0007] The present invention is further configured such that: a slider is fixedly connected to the first outer frame, a movable groove and a limiting plate for constraining the slider are provided inside the second outer frame, and an elastic element is provided between the slider and the movable groove.

[0008] By adopting the above technical solution, the elastic element can be a spring or a rubber pad with elastic force, which, together with the slider and the moving groove, can achieve the anti-vibration effect.

[0009] The present invention is further configured such that: the upper substrate has a plurality of sound-absorbing holes with openings that are smaller at the top and larger at the bottom.

[0010] By adopting the above technical solution, the sound-absorbing holes are set with a smaller top and a larger bottom to reduce sound refraction, which can further reduce or isolate sound.

[0011] The present invention is further configured such that a plurality of weight-reducing holes are formed on the lower substrate.

[0012] By adopting the above technical solution, the weight-reducing holes play a role in weight reduction.

[0013] The present invention is further configured such that the sound-absorbing holes are filled with environmentally friendly sound-absorbing cotton.

[0014] By adopting the above technical solution, the environmentally friendly sound-absorbing cotton is made of polyester fibers through stacking and hot pressing. It does not produce any harmful effects when in direct contact with human skin. It is a new type of sound-absorbing material that is non-toxic, harmless, and pollution-free.

[0015] The present invention is further configured such that the elastic element is a spring.

[0016] In summary, this utility model has the following beneficial effects:

[0017] The composite design of the upper substrate, lower substrate, and support plate, combined with the connection between the first outer frame, the second outer frame, and the upper and lower substrates, enhances the strength and vibration resistance of the car roof.
