[0019] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, this utility model discloses a heat-insulating and sound-insulating automotive glass, including an automotive glass body 1. The automotive glass body 1 has a vertically provided mounting groove 8 in the middle, and a frame 2 is provided in the mounting groove 8. A heat-insulating and sound-insulating film 9 is installed in the middle of the frame 2. The automotive glass body 1 has a first arc-shaped groove 6 on both sides, and the frame 2 has a second arc-shaped groove 10 on both sides. The first arc-shaped groove 6 and the second arc-shaped groove 10 are combined to form a cylindrical groove. A metal tube 4 is installed in the cylindrical groove, and a fixing component is installed in the metal tube 4 to lock and fix the frame 2 inside the mounting groove 8.

[0020] In this embodiment, the first arc groove 6 is provided with a third arc groove 7 at the end away from the opening, and the second arc groove 10 is provided with a fourth arc groove 11 at the end away from the opening. The third arc groove 7 and the fourth arc groove 11 are combined to form a positioning groove with an annular structure. The fixing component includes a connecting post 5 and a positioning ring 12. The connecting ring is provided in the metal tube 4, and the positioning ring 12 is installed on one end face inside the connecting post 5. The other end of the positioning ring 12 is inserted into the positioning groove. Specifically, after the connecting column rotates outward, the positioning ring on the connecting column can disengage from the positioning groove. After the positioning ring loses its blocking and limiting effect, the frame can be pulled upward from the mounting groove.

[0021] In this embodiment, the outer ring surface of the connecting post 5 is provided with external threads, the inner wall surface of the metal tube 4 is provided with internal threads, the connecting post 5 is connected to the metal tube 4 by the external threads engaging with the internal threads, and the outer end face of the connecting post 5 is provided with a cross groove.

[0022] In this embodiment, U-shaped grooves are formed by recesses on the front and rear sides of the frame 2. A matching rubber layer 3 is installed in each U-shaped groove. The outer side of the rubber layer 3 is fitted to the inner wall of the mounting groove 8. The rubber layer 3 is made of transparent rubber material.

[0023] In this embodiment, the edge of the frame 2 is flush with the edge of the car glass body 1. The frame 2 is made of transparent plastic material to ensure the flatness of the edge, so as not to affect the raising and lowering of the car glass body.

[0024] In this embodiment, the fastener is made of stainless steel, which increases its strength and prevents it from rusting.

[0025] In this embodiment, the heat insulation and sound insulation film 9 is not in contact with the inner wall surface of the mounting groove 8 on both sides to avoid adhesion and facilitate subsequent removal.

[0026] Working principle: The heat-insulating and sound-insulating film 9 is installed in the mounting groove 8 inside the car glass body 1 through the frame 2, so that the heat-insulating and sound-insulating film is completely placed inside the glass, avoiding direct contact with external objects, thereby preventing wear or damage caused by friction and scratches, extending service life and maintaining light transmission.

[0027] The frame 2 is embedded in the mounting groove 8, with its edge flush with the edge of the car glass body to ensure the overall structure is flat. The U-shaped grooves on the front and rear sides of the frame are inlaid with transparent rubber layers 3. The rubber layers are tightly fitted to the inner wall of the mounting groove, which plays a role in sealing and buffering, preventing dust and moisture from entering, while avoiding direct contact between the heat insulation and sound insulation film and the inner wall of the glass, reducing friction and air bubbles during installation.

[0028] The second arc-shaped grooves 10 on both sides of the frame are joined with the first arc-shaped grooves 6 on both sides of the automotive glass body to form a cylindrical groove, and the metal tube 4 is installed in the cylindrical groove.

[0029] The fasteners include a connecting post 5 with external threads and a positioning ring 12. The connecting post is screwed into the metal tube and fastened by thread engagement. The positioning ring is screwed into the positioning groove composed of a third arc groove 7 and a fourth arc groove 11 as the connecting post is screwed in, forming a radial lock to prevent the frame from loosening or falling out.

[0030] By inserting a tool (such as a screwdriver) into the cross groove at the end of the connecting post and rotating the connecting post, the frame can be quickly installed or removed, facilitating the maintenance or replacement of the heat insulation and sound insulation film.

[0031] The heat-insulating and sound-insulating film is independently fixed inside the frame and does not contact the inner wall of the mounting groove, forming an air isolation layer, which further enhances the heat insulation and sound insulation effects. The overall structure effectively improves the comfort and energy efficiency of automotive glass while ensuring light transmission.

[0032] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions conceived without inventive effort should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope defined in the claims.
