Technical Field

[0001] This utility model relates to the field of sound insulation pad technology, specifically to an anti-mildew car sound insulation pad. Background Technology

[0002] Automotive sound insulation materials are industrial materials specifically designed to address vibration and airborne noise generated during vehicle operation. Their main components are butyl rubber, rubber and plastics, and EVA / EPDM sheets. By being installed in key areas such as car doors, roof, chassis, and hood, they reduce noise transmission and are widely used in vehicle noise reduction modifications. Automotive sound insulation mats are an important accessory for enhancing the driving experience, effectively isolating noise and creating a quiet and comfortable driving environment.

[0003] Existing car sound insulation pads have the following drawbacks during use: During the rainy season, the long-term humid environment causes a large number of water molecules to seep into the sound insulation pad. The presence of a large number of water molecules inside for a long time can lead to the growth of mold, affecting the lifespan and sound insulation effect of the sound insulation pad. Therefore, there is room for improvement. Utility Model Content

[0005] Therefore, the technical solution adopted by this utility model is as follows: a mildew-proof car sound insulation pad, comprising: a main body, the main body comprising a heating film, a connector fixed to one side of the heating film, fiber fabric layers symmetrically fixed to both sides of the heating film, sound insulation cotton bonded to the surface of the fabric layers, non-woven fabric bonded to the surface of the sound insulation cotton, and a rubber layer bonded to the surface of the non-woven fabric.

[0006] Multiple grooves are arranged in an array on the surface of the sound insulation cotton, and bamboo charcoal particles are filled in the grooves.

[0007] In a preferred embodiment, the present invention can be further configured such that: a positive electrode wire and a negative electrode wire are disposed inside the heating film, and multiple resistance wires are connected in an array between the positive electrode wire and the negative electrode wire.

[0008] In a preferred embodiment, the present invention can be further configured such that the connector connects the positive electrode wire and the negative electrode wire.

[0010] In a preferred embodiment, the present invention can be further configured such that the surface of the rubber layer away from the sound insulation layer is provided with anti-slip texture.

[0011] By adopting the above technical solution, the beneficial effects achieved by this utility model are as follows:

[0012] 1. In this utility model, a heating film is provided, and fiber fabric layers are installed on both sides of the heating film. Sound insulation cotton is adhered to the limiting fabric layer, and a rubber layer is provided on the outside of the sound insulation cotton.

[0020] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.

[0021] Some embodiments of this utility model are described below with reference to the accompanying drawings.

[0022] Example 1:

[0023] Combination Figure 1-4 As shown, this embodiment provides a mildew-proof automotive sound insulation pad, including: a main body 100.

[0024] The main structure 100 includes a heating film 110, a connector 120 fixed to one side of the heating film 110, a fiber fabric layer 130 symmetrically fixed to both sides of the heating film 110, a sound insulation cotton 140 bonded to the surface of the fabric layer, a non-woven fabric 150 bonded to the surface of the sound insulation cotton 140, and a rubber layer 160 bonded to the surface of the non-woven fabric 150.

[0025] The heating film 110 is used to install the fiber fabric layer 130, and the limiting fabric layer is used to bond and fix the sound insulation cotton 140. The fiber fabric layer 130 and the sound insulation cotton 140 are symmetrically arranged on both sides of the heating film 110. Compared with the setting of a single layer of sound insulation cotton 140, the sound insulation effect can be further improved.

[0026] A positive electrode wire 111 and a negative electrode wire 112 are provided inside the heating film 110. Multiple resistance wires 113 are connected in an array between the positive electrode wire 111 and the negative electrode wire 112. One end of the positive electrode wire 111 and the negative electrode wire 112 are connected to the connector 120. The connector 120 is connected to the vehicle power supply through a wire. With this configuration, when the car is started, the current enters the positive electrode wire 111 through the connector 120, and then returns to the connector 120 through the resistance wires 113 and the negative electrode wires 112, forming a current loop. When the current passes through the resistance wires 113, the resistance wires 113 heat up due to their high resistance. This heats the fiber fabric layers 130 and the sound insulation cotton 140 on both sides, causing the moisture in them to evaporate and ensuring the dryness of the sound insulation cotton 140. This effectively prevents the sound insulation cotton 140 from developing mold.

[0027] In addition, the resistance wire 113 is arranged in an S-shape, which can effectively increase the heating area and ensure the uniformity of heating the fiber fabric layer 130 and the sound insulation cotton 140.

[0028] Multiple grooves 141 are arranged in an array on the surface of the sound insulation cotton 140. Non-woven fabric 150 is attached to the surface of the sound insulation cotton 140 and also to the inner wall of the grooves 141. Bamboo charcoal particles are filled in the grooves 141. The non-woven fabric 150 is used to separate the bamboo charcoal particles from the sound insulation cotton 140. The bamboo charcoal particles can absorb moisture in the sound insulation cotton 140 to prevent the sound insulation cotton 140 from getting damp and moldy. At the same time, the bamboo charcoal can absorb odors and harmful gases and can be reused.

[0029] The rubber layer 160 provides protection for the sound insulation cotton 140, preventing external moisture from directly contacting the sound insulation cotton 140. At the same time, the rubber layer 160 can absorb vehicle vibrations and improve the sound insulation effect. In addition, the surface of the rubber layer 160 is provided with anti-slip texture to ensure the stability of the entire sound insulation pad during installation.

[0030] The working principle and usage process of this utility model are as follows: When in use, the sound insulation pad is installed on the vehicle. The rubber layer 160 can absorb the vibration of the vehicle and reduce vibration noise. The double-layer sound insulation cotton 140 can effectively prevent external noise from entering the vehicle. At the same time, during the rainy season, the bamboo charcoal filled in the groove 141 can absorb the moisture in the sound insulation cotton 140 and reduce the moisture content in the sound insulation cotton 140. In addition, the current is introduced through the connector 120 and forms a circuit through the positive electrode wire 111, the resistance wire 113, and the negative electrode wire 112. When the current passes through the resistance wire 113, it heats up due to the high resistance, which in turn heats the fiber fabric layer 130 and the sound insulation cotton 140 on both sides, causing the moisture in them to evaporate and ensuring that the sound insulation cotton 140 is dry.

[0031] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
