[0023] The following further describes the specific embodiments of the present utility model with reference to the drawings. The same components are denoted by the same reference numerals.

[0024] It should be noted that the terms "front", "rear", "left", "right", "upper" and "lower" used in the following description refer to the directions in the drawings, and the terms "inner" and "outer" respectively refer to the directions towards or away from the geometric center of a specific component.

[0025] In order to make the content of the present utility model easier to be clearly understood, the following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model.

[0026] As Figures 1 to 3 shown, an environment-friendly automobile sound insulation pad includes an upper pad sleeve 1 and a lower pad sleeve 2. The outer surfaces of the upper pad sleeve 1 and the lower pad sleeve 2 are coated with a waterproof coating, and the upper pad sleeve 1 and the lower pad sleeve 2 themselves have waterproof functions.

[0027] A sound insulation component is provided between the upper pad sleeve 1 and the lower pad sleeve 2, and a sealing component is provided between the upper pad sleeve 1 and the lower pad sleeve 2. The sealing component includes a clamping groove 6 fixedly arranged on the inner side of the upper pad sleeve 1. A clamping ring 7 is fixedly arranged on the outer side surface of the lower pad sleeve 2. The clamping ring 7 can be clamped in the clamping groove 6. Both the clamping ring 7 and the clamping groove 6 are made of rubber material. By placing the sound insulation component between the upper pad sleeve 1 and the lower pad sleeve 2 and then clamping the clamping ring 7 with the clamping groove 6, it can prevent moisture from entering the upper pad sleeve 1 and the lower pad sleeve 2 from the interface of the upper pad sleeve 1 and the lower pad sleeve 2.

[0028] A fixing component is provided between the upper pad sleeve 1 and the lower pad sleeve 2 and the sound insulation component. The fixing component includes a male buckle 9 fixedly arranged on the non-woven fabric layer 5. Female buckles 8 are provided on the sides of the upper pad sleeve 1 and the lower pad sleeve 2 that are close to each other. The male buckle 9 and the female buckle 8 can be engaged. By placing the sound insulation component between the upper pad sleeve 1 and the lower pad sleeve 2 and then engaging the male buckle 9 with the female buckle 8, it can prevent the sound insulation component from being fixed between the upper pad sleeve 1 and the lower pad sleeve 2.

[0029] The sound insulation component includes a base layer 3. The outer surface of the base layer 3 is coated with a heat insulation coating, so that the sound insulation pad has a heat insulation function. Sound insulation layers 4 are provided on both the upper and lower sides of the base layer 3. The sound insulation layers 4 are made of sound insulation cotton, and the sound insulation layers 4 are in a honeycomb shape, so that the sound insulation pad has better sound insulation performance. Since the upper pad sleeve 1 and the lower pad sleeve 2 are not easily waterlogged, the service life of the sound insulation layer 4 can be extended. At the same time, the sound insulation cotton is not easy to breed bacteria. A non-woven fabric layer 5 is provided on the side of the sound insulation layer 4 away from the base layer 3. The non-woven fabric layer 5 is made of PLA non-woven fabric. The non-woven fabric layer 5 is non-flammable and biodegradable, which can protect the sound insulation layer 4 and is also more environmentally friendly.

[0030] The above are only the preferred embodiments of the patent of the present utility model, and are not used to limit the patent of the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the patent of the present utility model shall be included in the protection scope of the patent of the present utility model.
