AI Technical Summary
Traditional sound insulation measures for engineering vehicle cabs are insufficient in sound insulation performance and are prone to condensation. Existing sound insulation cotton does not significantly reduce noise.
It adopts a double-layer glass design with an aluminum alloy frame sandwiched in the middle and filled with desiccant. The outer and inner layers are bonded with sealant. The aluminum alloy frame has a rectangular or ring-shaped cross section. The glass sheet thickness is 5-10mm, the gap width is 8-15mm, and the inner and outer sealants are butyl rubber and polysulfide rubber or silicone rubber, respectively.
It effectively blocks noise, provides lightweight and high-strength support, and prevents air leakage or water seepage.

The inner sealant connects the aluminum alloy frame and the glass panes, while the outer sealant fills the gap between the glass panes and the aluminum alloy frame. The double-glazed design combined with the hollow structure effectively blocks noise; the aluminum alloy frame provides lightweight, high-strength support; and the double-seal design prevents air leakage or water seepage.
[0006] A further improvement of the sound insulation panel structure for the cab of an engineering vehicle in this utility model is that the cross-section of the aluminum alloy frame is rectangular or annular.
[0007] A further improvement of the sound insulation panel structure for the cab of an engineering vehicle in this utility model is that the thickness of the glass sheet is 5-10mm and the gap width between the two glass sheets is 8-15mm.
[0008] A further improvement of the sound insulation panel structure for the cab of an engineering vehicle in this utility model is that the inner sealant is butyl rubber and the outer sealant is polysulfide rubber or silicone rubber.
[0009] Compared with the prior art, the beneficial effects of this utility model are as follows: Double-glazed windows combined with a hollow structure effectively block noise; an aluminum alloy frame provides lightweight, high-strength support; and a double-sealed design prevents air leakage or water seepage.

[0011] The components include: 1. Glass plate, 2. Desiccant, 3. Outer sealant, 4. Inner sealant, and 5. Frame. Detailed Implementation
[0012] The present invention will be further illustrated below with reference to specific embodiments. It should be understood that these embodiments are only for illustrating the present invention and not for limiting the scope of the present invention. After reading the present invention, any modifications of the present invention in various equivalent forms by those skilled in the art will fall within the scope defined by the appended claims.
[0013] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.
[0014] In the description of this utility model, it should be noted that the terms "vertical," "outer peripheral surface," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the utility model product is in use. They are used only for the convenience of describing this utility model and for simplifying the description, and do not indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first," "second," "third," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.
[0015] Furthermore, terms such as "vertical" do not imply that a component must be absolutely horizontal or suspended, but rather that it can be slightly tilted. Similarly, "horizontal" simply means that its direction is more horizontal relative to "vertical," and does not mean that the structure must be completely horizontal, but rather that it can be slightly tilted.
[0016] like Figure 1 As shown, a sound insulation panel structure for an engineering vehicle cab is characterized by comprising: Two glass plates 1 are symmetrically arranged, with a gap between them; An aluminum alloy frame 5 is disposed between two glass plates, wherein the interior of the aluminum alloy frame is hollow and filled with a desiccant 2; and A sealing assembly for bonding two glass panes and an aluminum alloy frame, comprising an inner sealant 3 and an outer sealant 4. The inner sealant connects the aluminum alloy frame and the glass panes, while the outer sealant fills the gap between the glass panes and the aluminum alloy frame. The double-glazed design combined with the hollow structure effectively blocks noise; the aluminum alloy frame provides lightweight, high-strength support; and the double-seal design prevents air leakage or water seepage.
[0017] Specifically, the aluminum alloy frame has a rectangular or ring-shaped cross-section.
[0018] Specifically, the thickness of the glass sheets is 5-10mm, and the gap width between the two glass sheets is 8-15mm.
[0019] Specifically, the inner sealant is butyl rubber, and the outer sealant is polysulfide rubber or silicone rubber.
[0020] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
