[0021] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the present invention provides a multi-layer explosion-proof automotive glass with high-strength shock resistance, comprising a first glass 1 and a second glass 2.

[0022] In this embodiment, the buffer explosion-proof layer 3 includes a rubber layer and an explosion-proof film. One side of the rubber layer is bonded and fixed to the inner wall of the mounting groove 11, and the other side is bonded and fixed to the explosion-proof film. The other side of the explosion-proof film is bonded and fixed to the second glass 2.
[0023] In this embodiment, the second glass 2 is provided with a plurality of first mounting holes, each of which is equipped with a connecting seat 4. The first glass 1 is provided with a second mounting hole opposite to the connecting seat 4, each of which is equipped with a fixing seat 9. The outer end face of the fixing seat 9 is provided with a countersunk hole, and the inner end face of the connecting seat 4 is provided with a screw hole. The buffer explosion-proof layer 3 is provided with a through hole opposite to the screw hole. The countersunk hole is provided with a bolt 10. The shank of the bolt 10 passes through the through hole and is threaded into the screw hole.
[0024] In this embodiment, the buffer connection assembly includes multiple positioning posts 8. Multiple cylindrical grooves are formed by recessing one end face of the first glass 1 facing the lifting plate 5. Columns 12 are vertically installed on the inner side of the fixing plate 7 opposite the cylindrical grooves. The columns 12 are inserted into the cylindrical grooves and are bonded and fixed to the cylindrical grooves. Positioning holes are provided on the outer end face of the fixing plate 7 opposite the columns 12. The positioning posts 8 are all installed on the lifting plate 5, and the other end of the positioning posts 8 is inserted into the positioning holes.
[0025] In this embodiment, the buffer connection assembly also includes multiple compression springs 13 and rubber rings 14. Multiple annular grooves are provided on the outer ring surface of the positioning post 8. The rubber rings 14 are installed in the annular grooves. The outer ring surface of the rubber rings 14 is in frictional contact with the inner wall surface of the positioning hole. One end of each compression spring 13 is installed at the deepest part of the positioning hole, and the other end is fixedly connected to the end face of the positioning post 8.
[0026] In this embodiment, multiple rubber blocks 6 are installed between the lifting plate 5 and the fixed plate 7 to further enhance the vertical buffering effect of the first and second glass.
[0027] In this embodiment, the outer surface of the second glass 2 is flush with the outer surface of the first glass 1 to ensure the flatness of the outer surface.
[0028] In this embodiment, the fixing plate 7 and the column 12 are integrally injection molded from stainless steel, which increases the sturdiness.
[0029] In this embodiment, a buffer space is formed between the lifting plate 5 and the fixed plate 7 for the first glass 1 to descend.
[0030] Working principle: The first glass 1 serves as the main substrate, with a pre-machined mounting groove 11 on its outer side. The second glass 2 serves as the replaceable outer protective layer, and is independently fixed in the mounting groove through the cooperation of the connecting seat 4, the fixing seat 9, and the bolts 10. When the second glass is damaged due to impact, flying stones, or other reasons, it is not necessary to replace the entire large glass. Simply unscrew the bolts 10, and the damaged second glass 2, along with its connecting seat 4, can be removed and replaced, significantly reducing maintenance costs.
[0031] A buffer explosion-proof layer 3 is provided between the inner wall of the mounting groove 11 of the second glass 2 and the first glass 1. This layer is composed of a rubber layer and an explosion-proof film.
[0032] Buffering effect: The rubber layer has good elasticity and energy absorption properties. When the second glass is subjected to a positive impact from the outside of the vehicle or in-plane stress caused by the torsional deformation of the vehicle body, the rubber layer can undergo elastic deformation to absorb and disperse the impact energy, preventing the stress from being directly and completely transmitted to the first glass, thereby protecting the first glass from damage and reducing the impact on the second glass. The bolt and the countersunk hole are not threaded. After the second glass moves inward, it can push the bolt along the countersunk hole toward the interior of the car, thus smoothly compressing the rubber layer and playing a buffering role.
[0033] Explosion-proof function: The explosion-proof film has high strength and adhesion. Even if the second glass breaks due to a strong impact, the explosion-proof film can firmly bond the glass fragments together, preventing them from flying and injuring people, thus improving safety.
[0034] The end of the first glass 1 is fixedly connected to the fixing plate 7 via the column 12. The fixing plate 7 and the lifting plate 5 for installation on the vehicle body are connected by multiple positioning columns 8. The positioning columns 8 are inserted into the positioning holes of the fixing plate 7, forming the main vertical motion guide mechanism.
[0035] Spring buffer: A compression spring 13 is installed between each positioning hole and the end of the positioning post 8. When the vehicle is driving on a bumpy road and vibrates, the first glass can move up and down along the positioning post. When it moves down, the compression spring 13 is compressed and stores energy. When the vibration trend is upward, the compression spring 13 releases energy and pushes the first glass to move. The repeated compression and rebound of the compression spring effectively absorbs and dissipates the vertical vibration energy from the frame, avoids the vibration from being directly transmitted to the glass body, and significantly improves the shock resistance and durability of the glass under dynamic load.
[0036] Frictional damping: The rubber ring 14, fitted onto the annular groove of the positioning post 8, maintains frictional contact between its outer ring and the inner wall of the positioning hole. During the up-and-down movement of the first glass 8 with vibration, the rubber ring 14 generates continuous frictional resistance with the hole wall. This frictional force can convert the vibrational kinetic energy into heat energy and dissipate it, thereby rapidly attenuating the vibration amplitude and preventing the glass from generating excessive reciprocating oscillations or resonance, thus playing a role in damping and vibration reduction.
[0037] Auxiliary buffer and limit: The rubber block 6, placed between the fixed plate 7 and the lifting plate 5, provides auxiliary elastic cushioning during vibration and acts as a soft limit when the vibration amplitude is large, preventing rigid collisions between the internal parts of the buffer connection assembly.
[0038] The buffer space reserved between the fixed plate 7 and the lifting plate 5 provides sufficient vertical movement for the first glass assembly, ensuring that the buffer mechanism can play its full role.
[0039] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions conceived without inventive effort should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope defined in the claims.
