Description

Technical Field

[0001] This application relates to the field of automotive parts technology, and in particular to a car roof heat insulation pad with sound insulation effect. Background Technology

[0002] As is well known, the latest standard "Terms and Definitions for Types of Motor Vehicles and Trailers" defines a motor vehicle as follows: a non-rail-borne vehicle that is powered and has four or more wheels, primarily used for: carrying people and goods; and towing vehicles that carry people and goods. Motor vehicle parts are the various units that make up the whole motor vehicle and products that serve the motor vehicle.

[0003] Currently, automotive headliners are a crucial component of vehicles, serving to reduce heat transfer to the interior. However, the applicant has found that existing headliners are primarily made of textile fabrics and sponge composite materials. After prolonged use, the sound-absorbing sponge layer inside the headliner gradually softens and deforms, making it difficult to achieve effective sound absorption. Furthermore, the existing sound-absorbing sponge layer is mostly integrated with the headliner, making it difficult to replace easily, thus limiting its usability.

[0004] Therefore, in response to the aforementioned technologies, it is necessary to propose a car roof heat insulation pad with sound insulation effect. Utility Model Content

[0005] The purpose of this invention is to provide a car roof heat insulation pad with sound insulation effect to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A car roof heat insulation pad with sound insulation effect, comprising:

[0008] The heat insulation pad body has a groove inside it;

[0009] A sound-absorbing sponge pad, wherein the sound-absorbing sponge pad is placed in the groove;

[0010] Four composite springs are provided, each of which is installed inside the heat insulation pad body through a connecting groove. The other end of each composite spring is fixedly connected to a limiting block, and the bottom of the limiting block is tightly fitted to the sound insulation sponge pad.

[0011] A protective layer is attached to the heat insulation pad body via a connecting component;

[0012] The mounting components are disposed on both sides of the heat insulation pad body and are used to fix the heat insulation pad body in the use position.

[0013] As a further embodiment of this utility model: the connecting component includes four connecting blocks, all four connecting blocks are fixedly connected to the bottom of the protective layer, and a rubber block is fixedly connected to the bottom of the connecting block. The heat insulation pad body has four corresponding limiting grooves, and a rubber block is fixedly connected to the limiting groove. The rubber block is inserted into the limiting groove through the rubber block.

[0014] As a further embodiment of this utility model: the mounting assembly includes four mounting plates, all of which are disposed within the heat insulation pad body through mounting grooves. Each mounting plate has a mounting hole, and a threaded ring is provided in the mounting hole. A positioning bolt is threaded into the threaded ring.

[0015] As a further improvement of this utility model, one end of each of the plurality of limiting blocks is fixedly connected to a ring handle with an anti-slip sleeve.

[0016] As a further improvement of this utility model, a waterproof coating is provided on the protective layer.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] By setting up installation components, the heat insulation pad body is fixed in the usage position with the cooperation of the mounting plate, threaded ring, and positioning bolts. The heat insulation pad body and the sound insulation foam pad work together to achieve heat insulation, heat preservation, and sound insulation. When the sound insulation foam pad deforms and softens due to prolonged use, the connecting components, with the cooperation of the connecting block, rubber block one, and rubber block two, allow rubber block one to be removed from the limiting groove, thus separating the protective layer from the heat insulation pad body. Then, the composite spring and the limiting block work together to separate the limiting block from the sound insulation foam pad, allowing the sound insulation foam pad to be removed and replaced. Its overall structure is relatively simple and practical, providing both heat insulation and sound insulation. Compared to existing technologies, it facilitates the disassembly and replacement of the sound insulation foam pad in the car roof heat insulation pad, ensuring its sound insulation effect.
