Description

Technical Field

[0001] The utility model relates to the technical field of hole plugging patches, in particular to a hole plugging patch for automobiles which is not easy to fall off. Background Art

[0002] Car hole plugging patches that are not easy to fall off generally refer to patches used to cover unwanted holes or openings on the car to prevent dust, water or other impurities from entering. These patches are usually made of durable materials such as rubber, silicone or other synthetic materials. They can fit the holes tightly and resist adverse weather conditions.

[0003] After searching, a flame-retardant automobile body hole plugging patch with announcement number CN220724027U includes a silicone layer, a first sound insulation cotton is arranged at the bottom of the silicone layer, a fastening layer is embedded in the bottom of the first sound insulation cotton, a second butyl rubber is arranged at the bottom of the first sound insulation cotton, a release paper is arranged at the bottom of the second butyl rubber, a groove is opened on the fastening layer, a clamping block is arranged on the silicone layer, the clamping block passes through the first sound insulation cotton and is clamped into the groove, and the maximum diameter of the clamping block is larger than the diameter of the middle position of the groove. The utility model extrude the fastening layer through the clamping block, so that the fastening layer expands and extrudes the target hole wall, the hole plugging patch is clamped in the target hole, and the second butyl rubber adheres the hole plugging patch to the body, thereby enhancing the stability of the hole plugging patch, so that the hole plugging patch will not fall off when the vehicle passes through a bumpy road section or when the vehicle moves at high speed, thereby extending the service life of the patch.

[0004] Based on the above patent, by setting the first sound insulation cotton, the sound insulation effect of the hole-blocking patch is greatly improved, and by setting a snap-in block at the bottom of the silicone layer and opening a groove on the fastening layer, when installing the hole-blocking patch, first snap the fastening layer into the target hole, then tear off the release paper, align the snap-in block with the groove and press it, embed the fastening layer into the first sound insulation cotton, and at the same time, stick the hole-blocking patch to the car body where the target hole is located through the second butyl adhesive. At the same time, the snap-in block is inserted into the groove, so that the snap-in block squeezes the fastening layer, so that the fastening layer expands and squeezes the target hole wall, so that the hole-blocking patch is snapped into the target hole, and at the same time, in the presence of the second butyl adhesive Under the same action, the hole-plugging patch is fixed at the position of the target hole, which enhances the stability of the hole-plugging patch and prevents it from falling off when the vehicle passes through bumpy roads or moves at high speed, thereby extending the service life of the patch. At the same time, both the silicone layer and the fastening layer are made of fire-proof silicone material with flame retardant effect. However, when the hole-plugging patch in the patent is in the inner hole groove of the car, when the vehicle is bumped during operation, the hole-plugging patch for the car will fall off due to the bumps. After the hole-plugging patch falls off, the originally covered holes are exposed, which will cause the airflow inside and outside the car to communicate with each other, affecting the air tightness and sound insulation effect inside the car.
