[0032] Based on this, please refer to Figures 1 to 3 The utility model provides a frame assembly 1 for fixing glass 2, comprising a first frame body 11 and a second frame body 12. The first frame body 11 has a first recessed portion 111, the second frame body 12 has a second recessed portion 121, and the second frame body 12 is detachably connected to the first frame body 11. The first recessed portion 111 and the second recessed portion 121 cooperate to form a clamping space. The clamping space is filled with adhesive 17, and the edge of the glass 2 is clamped in the clamping space. That is, the side of the glass 2, a part of the inner surface of the glass 2 and a part of the outer surface of the glass 2 are located in the clamping space. The edge of the glass 2 is clamped in the clamping space, so that the glass 2 is mechanically fixed by the first frame body 11 and the second frame body 12, preventing the glass 2 from falling out of the clamping space. Specifically, the first recessed portion 111 and the second recessed portion 121 can be semi-open recesses such as L-shaped or C-shaped. The two can cooperate to form a clamping space with a single-side opening, clamping the side surface and a portion of the outer and inner surfaces of the edge of the glass 2 within the clamping space, that is, the edge of the glass 2 extends into the clamping space. In addition, the frame assembly 1 fills the clamping space with adhesive 17 to eliminate the gap between the clamping space and the glass 2, thereby completing the fixation of the glass 2 to the frame assembly 1. Those skilled in the art can set the appropriate first recessed portion 111 and second recessed portion 121 according to the specific type of glass 2, without specific limitation.

[0033] It can be understood that the frame assembly 1 provided by the present invention forms a clamping space through the cooperation of the first recessed portion 111 and the second recessed portion 121, which restricts the edge of the glass 2 within the clamping space, and fills the clamping space with adhesive 17, so that the adhesive fixation and mechanical fixation work together, effectively avoiding the glass 2 from falling off after long-term use, thereby improving safety.

[0034] In some embodiments, the second frame 12 is provided with a first stepped through-hole 122, and the first frame 11 is provided with a threaded hole 112 corresponding to the first stepped through-hole 122. A first fastening bolt 13 is disposed within the first stepped through-hole 122 and the threaded hole 112. The first fastening bolt 13 is secured through the first stepped through-hole 122 and the threaded hole 112, thereby securing the second frame 12 to the first frame 11. Furthermore, the head of the first fastening bolt 13 is disposed within the first stepped through-hole 122, thereby protecting the first fastening bolt 13 from exposure, reducing the degree of corrosion to the first fastening bolt 13 from the external environment, and enhancing the aesthetic appearance of the frame assembly 1 after installation.

[0035] In some embodiments, the second frame body 12 is provided with a mounting hole 123, and the first frame body 11 is provided with a second stepped through hole 113 corresponding to the mounting hole 123. A second fastening bolt 14 is provided in the second stepped through hole 113. The second fastening bolt 14 can secure the first frame body 11 to the vehicle frame 3, thereby allowing the frame assembly 1 to be easily installed on the rail vehicle, improving the convenience of installation.

[0036] In some embodiments, bolt plugs 15 are provided at the heads of the first fastening bolts 13 and the second fastening bolts 14, and a first sealant layer 16 is provided in the first stepped through hole 122 and the mounting hole 123. The bolt plugs 15 prevent the first fastening bolts 13 and the second fastening bolts 14 from being contaminated by the first sealant layer 16, facilitating removal of the first fastening bolts 13 and the second fastening bolts 14.

[0037] In some embodiments, the outer surface of the second frame 12 is flush with the outer surface of the glass 2. The edge of the glass 2 has a stepped structure. The stepped portion of the glass 2 is positioned within the clamping space, while the outer surface of the glass 2 outside the clamping space is flush with the outer surface of the second frame 12. This ensures that the outer surface of the glass assembly is flush, ensuring that the rail vehicle's appearance meets requirements. This also prevents the edges of the glass 2 from coming into contact with the outside world, reducing the risk of glass 2 cracking.

[0038] The present invention further provides a glass assembly comprising: a glass 2 and any of the above-described frame assemblies 1. Specifically, the edge of the glass 2 extends into the clamping space and is secured to the frame assembly 1 via adhesive 17 and mechanical action. This prevents the glass 2 from falling off after prolonged use, providing excellent safety.

[0039] Preferably, the second frame 12 is provided with a hoisting hole to facilitate hoisting of the glass assembly during installation.

[0040] In some embodiments, a sealing ring 114 is provided on the first recessed portion 111, and the sealing ring 114 abuts against the glass 2. The sealing ring 114 is provided between the first frame 11 and the glass 2, and the sealing ring 114 ensures that the glass 2 and the frame assembly 1 meet the sealing requirements after installation.

[0041] In some embodiments, the gap between the glass 2 and the second frame 12 is filled with adhesive 17. Filling the gap between the glass 2 and the second frame 12 with adhesive 17 prevents foreign matter from entering the gap, strengthens the adhesive effect, and prevents foreign matter from damaging the edges and corners of the glass 2, thereby preventing the glass 2 from shattering.

[0042] The frame assembly and glass assembly of the present invention can be applied to vehicles including but not limited to automobiles, rail vehicles, and non-road vehicles, wherein rail vehicles include but are not limited to locomotives, motor vehicles, high-speed railways, trains, subways, etc.

[0043] The present invention further provides a rail vehicle, comprising a vehicle frame 3 and any of the above-mentioned glass assemblies, wherein the glass assembly is detachably mounted on the vehicle frame 3 .

[0044] In some embodiments, an adjustment pad 18 is provided between the frame 3 and the first frame 11. The adjustment pad 18 adjusts the position of the glass 2 so that the outer surfaces of the frame 3 and the glass 2 are flush, thereby ensuring a consistent overall exterior surface of the rail vehicle. Specifically, the adjustment pad 18 is made of aluminum or other metal. Those skilled in the art will be able to select adjustment pads of varying thickness and material to adjust the spacing between the glass assembly and the frame 3, ensuring a consistent overall exterior surface of the rail vehicle.

[0045] Preferably, Figure 3 As shown, it also includes an elastic pad 181, which is clamped between the vehicle frame 3 and the frame assembly. The elastic pad 181 is arranged on the side of the frame assembly away from the glass, so that the elastic pad 181 can contact the first frame 11, the second frame 12 and the adjustment pad 18 at the same time. The elastic pad 181 provides a buffering and sealing effect on the glass assembly, avoiding direct contact between the glass assembly and the vehicle frame 3 after installation, and preventing excessive stress between the two from causing the glass 2 to shatter. Preferably, the material of the elastic pad 181 is aluminum plate, which has rigidity, elasticity and toughness, and can withstand the stress generated by the heavy weight of the glass 2 and the high-speed operation of the rail vehicle and provide corresponding buffering effect.

[0046] Preferably, the vehicle frame 3, the glass assembly and the adjustment pad 18 or the elastic pad 181 are enclosed to form an installation gap, and a second sealant layer 19 is provided in the installation gap. The second sealant layer 19 can prevent external moisture or air and other substances from entering the installation gap, thereby improving the sealing of the overall structure and preventing the elastic pad 181 from being eroded by the external environment. Specifically, with the cooperation of the second sealant layer 19 and the elastic pad 18, it is possible to prevent external rainwater or dust and other substances from penetrating into the interior of the rail vehicle through the installation gap. More preferably, a steel wire rope 191 is provided in the second sealant layer 19, and the second sealant layer 19 can be removed by pulling the steel wire rope 191, making it convenient for disassembly and replacement. Specifically, during installation, the steel wire rope 191 is placed on the surface of the adjustment pad 18 or the elastic pad 181, and then sealant is injected to form the second sealant layer 19. When the glass assembly needs to be replaced, the second sealant layer 19 can be quickly removed by pulling the steel wire rope 191, thereby improving replacement efficiency.
