Description

Technical Field

[0001] The utility model relates to the technical field of recreational vehicle accessories, in particular to a heat-insulating and noise-reducing carriage structure. Background Art

[0002] In the prior art, RV compartments are usually insulated by using rock wool boards or by thickening the outer shell. When used for a long time in a cold environment, the cold air outside the compartment will penetrate into the compartment. Due to the temperature difference between the inside and outside of the compartment, water droplets or condensed ice will form on the inner wall of the compartment, resulting in poor insulation effect, which affects the user's use. Moreover, RV compartments are thinner than buildings, and have poor sound insulation effect. The loud noise will affect the driver's rest. Utility Model Content

[0003] The utility model aims to provide a heat-insulating and noise-reducing carriage structure in view of the defects and shortcomings of the prior art.

[0004] To achieve the above-mentioned purpose, the technical solution adopted by the utility model is: a heat-insulating and noise-reducing car structure, including a car body, the car body is a composite structure, and its innovation lies in: the car body includes an outer frame, a mounting plate is arranged inside the outer frame, a U-shaped sound-absorbing tube is arranged in matrix on the mounting plate, and sound-absorbing cotton is arranged on the inner wall of the sound-absorbing tube, a polyester foam board is also sleeved on the sound-absorbing tube and bonded to the back of the mounting plate, a waterproof board is arranged on the front of the mounting plate, a decorative board is arranged on the front of the waterproof board, a sound-absorbing board is arranged on the back of the polyester foam board, an arc-shaped mounting groove is provided on the sound-absorbing board for installation with the sound-absorbing tube, an inner board is arranged on the back of the sound-absorbing board, and thermal insulation glue is filled between the sound-absorbing board and the inner board.

[0005] Furthermore, a layer of waterproof glue is coated on the surface of the sound-absorbing tube.

[0006] Furthermore, the surface of the mounting plate and the pipe opening of the sound-absorbing pipe are located on the same vertical line.

[0007] After adopting the above structure, the utility model has the following beneficial effects:

[0008] The utility model can block external cold air from entering the interior of the car by arranging a polyester foam board, and at the same time, the thermal insulation glue also blocks a large amount of heat in the car from dissipating to the outside, thereby increasing the thermal insulation of the car, and the waterproof board can block external water vapor, thereby preventing ice from forming in the car; by arranging a U-shaped sound-absorbing tube, the noise can be absorbed and then reflected and silenced in the sound-absorbing tube, and at the same time absorbed by the sound-absorbing cotton, thereby playing a role of sound insulation, and at the same time, the sound-absorbing board can further play a role of noise reduction.
