DETAILED DESCRIPTION

[0022] Clearly, the described embodiments are merely a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the present application.

[0023] Please refer to Figures 1-4 The application discloses a kind of automobile door panel soundproofing waterproof rubber sealing strips, including rubber strip 1, the inner side of rubber strip 1 is provided with soundproofing waterproof mechanism 2, the lower portion of rubber strip 1 is provided with bonding mechanism 3.

[0024] Further, the soundproofing device includes a U-shaped groove 201, which is formed on the surface of the rubber strip 1. The inner side of the rubber strip 1 is provided with a cavity 202, and the inner side of the cavity 202 is fixedly connected with a partition block 203. The waterproof device includes a waterproof fin 204, which is fixedly connected to the rubber strip 1. The surface of the rubber strip 1 is fixedly connected with a friction strip 205. Through the arrangement of the U-shaped groove 201, the cavity 202, the partition block 203, the waterproof fin 204 and the friction strip 205, when in use, the U-shaped groove 201 is formed on the surface of the rubber strip 1. When sound waves propagate to the rubber strip 1, the U-shaped groove 201 can change the propagation path and reflection mode of the sound waves, causing part of the sound waves to continuously reflect and refract in the groove, consuming the energy of the sound waves, thereby achieving a certain soundproofing effect. The cavity 202 on the inner side of the rubber strip 1 and the partition block 203 fixedly connected in the cavity 202 form a structure similar to a resonance chamber. When external sound waves enter, the air in the cavity 202 will vibrate, and the partition block 203 will affect the mode and frequency of air vibration, causing sound waves of different frequencies to interfere and cancel each other in the cavity 202, further preventing sound waves from penetrating through the rubber strip 1 into the vehicle, effectively reducing the noise level entering the vehicle and improving the soundproofing effect of the automobile door panel. The waterproof fin 204 is fixedly connected to the rubber strip 1. When the door is closed, the waterproof fin 204 tightly fits the corresponding part of the door frame. Due to its special shape and position design, it can effectively block rainwater and other liquids from flowing into the vehicle through the gap between the door and the door frame. Even if the vehicle encounters rainwater or water accumulation during driving, the waterproof fin 204 can prevent liquid penetration by relying on its flexibility and tightness, ensuring the dryness of the vehicle environment. The friction strip 205 fixedly connected to the surface of the rubber strip 1 increases the friction when the rubber strip 1 contacts the door or the door frame. During installation, this friction helps the rubber strip 1 to be better fixed on the door or the door frame, preventing it from being easily displaced. In the case of long-term opening and closing of the door and vibration of the vehicle during driving, the friction strip 205 can continuously maintain the positional stability of the rubber strip 1, ensuring that the sealing structure is not damaged, thereby maintaining good soundproofing and waterproof performance.

[0025] Further, the cavity 202 is arranged symmetrically with the central axis of the rubber strip 1, and the partition blocks 203 are arranged in multiple groups at equal intervals on the surface of the cavity 202. Through the arrangement of the cavity 202, in use, the cavity 202 and the partition blocks 203 fixedly connected in the cavity 202 form a structure similar to a resonance chamber, which can effectively reduce the noise volume transmitted into the vehicle.

[0026] Further, the waterproof wing 204 is arranged symmetrically with the central axis of the rubber strip 1, and the friction strips 205 are arranged in multiple groups at equal intervals on the surface of the cavity 202. Through the arrangement of the friction strips 205, in use, the friction strips 205 fixedly connected on the surface of the rubber strip 1 increase the friction when the rubber strip 1 contacts the door or the door frame, preventing the rubber strip 1 from being easily displaced.

[0027] Further, the adhesive mechanism 3 comprises an adhesive groove 301, which is opened below the rubber strip 1, the surface of the adhesive groove 301 is connected with a primer layer 302, the lower surface of the primer layer 302 is fixedly connected with a glue layer 303, the lower part of the glue layer 303 is provided with a curing agent layer 304, the outer side of the curing agent layer 304 is adhered with a film 305, one end of the film 305 is fixedly connected with a curled edge 306. Through the setting of the adhesive groove 301, the primer layer 302, the glue layer 303, the curing agent layer 304, the film 305 and the curled edge 306, when not in use, the film 305 completely covers the outer side of the curing agent layer 304, which plays a protective role for the curing agent layer 304, preventing it from being activated or contaminated in advance. When the rubber strip 1 is installed on the corresponding position of the automobile door panel, first, the rubber strip 1 is attached to the door panel, so that the adhesive groove 301 is aligned with the part of the door panel that needs to be adhered, then the film 305 is torn off by holding the curled edge 306. Because of the existence of the curled edge 306, it is not necessary to find the film head, which is more convenient. Because the film 305 is cut into sections, each section of the film 305 has a curled edge 306, and the tail of the film 305 is below the curled edge 306 on the surface of the second section of the film 305. Therefore, when the rubber strip 1 is installed, the film 305 can be slowly torn off, and the rubber strip 1 will not be mixed together due to the glue. The glue layer 303 starts to contact with the surface of the door panel. The high-performance acrylate glue selected for the glue layer 303 has the characteristic of high initial viscosity, which quickly forms a preliminary adhesive force with the surface of the door panel, so that the rubber strip 1 can be preliminarily positioned on the door panel and maintained in a certain attached state. With the peeling of the film 305, the curing agent layer 304 is exposed and contacts with the air, and is affected by the temperature of the door panel surface. The curing agent is activated and starts to promote the cross-linking reaction of the glue layer 303. In the cross-linking reaction process, the high molecular chains in the glue layer 303 gradually connect with each other to form a three-dimensional network structure, which gradually changes from liquid to solid state, and forms a high-strength, high-toughness chemical bond with the surface of the door panel and the surface of the adhesive groove 301 of the rubber strip 1. The primer layer 302 plays a key bridge role in this process. Its special high molecular polymer material is tightly combined with one end of the rubber strip 1 and fully infiltrated and combined with the other end of the glue layer 303, which further enhances the stability and durability of the entire adhesive structure. Through this curing reaction, the rubber strip 1 and the automobile door panel achieve high-strength adhesion, which can resist external forces brought by various complex working conditions such as opening and closing of the door, driving vibration, etc. during long-term use of the automobile, ensuring that the rubber strip 1 is always firmly attached to the door panel and maintaining good sealing performance, thereby ensuring the effective play of the sound insulation, waterproof and other functions of the automobile door panel.

[0028] Further, the adhesive mechanism 3 is provided with two groups, and the film 305 is provided with multiple groups at equal intervals on the outer side of the curing agent layer 304. Through the setting of the adhesive mechanism 3, the two groups of adhesive mechanisms 3 can make the rubber strip 1 adhere more stably.

[0029] Working principle: when not in use, the film 305 completely covers the outside of the curing agent layer 304, playing a protective role for the curing agent layer 304, preventing it from being activated prematurely or contaminated, when the rubber strip 1 is installed on the corresponding position of the automobile door panel, first make the rubber strip 1 adhere to the door panel, make the adhesive groove 301 align with the part of the door panel that needs to be bonded, then pick up the edge 306 and tear off the film 305, due to the existence of the edge 306, it is not necessary to find the film head, it is more convenient, because the film 305 is one after another, each film 305 has an edge 306, and the tail of the film 305 is below the surface edge 306 of the second film 305, so when the rubber strip 1 is installed, the film 305 can be slowly torn off, the rubber strip 1 will not be mixed together because of the glue, the glue layer 303 starts to contact with the surface of the door panel, the high-performance acrylic glue selected for the glue layer 303 has the characteristic of high initial viscosity, which can quickly form a preliminary adhesive force with the surface of the door panel, so that the rubber strip 1 can be preliminarily positioned on the door panel and maintain a certain attached state, with the peeling of the film 305, the curing agent layer 304 is exposed and contacts with the air, at the same time, it is affected by the temperature of the door panel surface, the curing agent is activated and starts to promote the crosslinking reaction of the glue layer 303, in the process of crosslinking reaction, the high molecular chains in the glue layer 303 gradually connect with each other to form a three-dimensional network structure, which gradually changes from liquid to solid, and forms a high-strength, high-toughness chemical bond with the surface of the door panel and the surface of the adhesive groove 301 of the rubber strip 1, the primer layer 302 plays a key bridge role in this process, its special high molecular polymer material is tightly combined with one end of the rubber strip 1 and fully infiltrated and combined with the other end of the glue layer 303, further enhancing the stability and durability of the entire adhesive structure, through this curing reaction, the rubber strip 1 and the automobile door panel realize high-strength adhesion, which can resist the external force brought by various complex working conditions such as opening and closing of the car door, driving vibration, etc. during long-term use of the car, ensuring that the rubber strip 1 is always firmly attached to the door panel and maintaining good sealing performance, thereby ensuring the effective play of the sound insulation, waterproof and other functions of the automobile door panel, the U-shaped groove 201 is opened on the surface of the rubber strip 1, when the sound wave propagates to the rubber strip 1, the U-shaped groove 201 can change the propagation path and reflection mode of the sound wave, so that part of the sound wave is continuously reflected and refracted in the groove, consuming the energy of the sound wave, thereby playing a certain sound insulation effect, the cavity 202 inside the rubber strip 1 and the partition block 203 fixedly connected in the cavity 202 form a structure similar to a resonance chamber, when external sound waves enter, the air in the cavity 202 will vibrate, the partition block 203 will affect the mode and frequency of air vibration, so that sound waves of different frequencies interfere with and cancel each other in the cavity 202, further preventing sound waves from penetrating through the rubber strip 1 into the car, effectively reducing the noise volume entering the car and improving the sound insulation effect of the automobile door panel, the waterproof fin 204 is fixedly connected on the rubber strip 1, when the door is closed, the waterproof fin 204 tightly adheres to the corresponding part of the door frame,Due to the special shape and position design, it can effectively block the liquid such as rainwater from flowing into the vehicle along the gap between the door and the door frame, even if the vehicle encounters rainwater flushing or water accumulation during driving, the waterproof fin 204 can prevent liquid penetration by relying on its flexibility and close fit, ensure the dryness of the vehicle environment, the friction strip 205 fixedly connected on the surface of the rubber strip 1 increases the friction when the rubber strip 1 contacts with the door or the door frame, which helps the rubber strip 1 to be better fixed on the door or the door frame during installation, preventing it from being easily displaced, under the condition of long-term opening and closing of the door and vibration of the vehicle, the friction strip 205 can continuously maintain the position stability of the rubber strip 1, ensure that the sealing structure is not damaged, so as to maintain good sound insulation and waterproof performance.
