Description

Technical Field

[0001] The utility model belongs to the technical field of instrument panels, and in particular relates to an anti-fog window structure for an engineering machinery display. Background Art

[0002] During use, the instrumentation of construction machinery often experiences fogging due to the large temperature difference between the inside and outside of the vehicle, obscuring the information within and hindering the driver's ability to read. Traditional instrument defogging methods often involve blowing hot air or waiting for the instrument to automatically operate for a period of time to raise the internal temperature and evaporate the fog. However, this method is time-consuming, affecting the driver's ability to read the information within the instrument. Therefore, an anti-fog structure for instruments is needed to solve the technical problem of instrument fogging.

[0003] Patent document CN204697438U discloses a fog-proof double-layer transparent cover, comprising a housing, an outer transparent cover, and an inner transparent cover. The outer transparent cover is sealed to the inner transparent cover, or the outer transparent cover and the inner transparent cover are each sealed to the housing, forming a sealed space between the outer transparent cover and the inner transparent cover. Although this utility model provides a double-transparent cover structure, one of the transparent covers needs to be fixed by a card box, while the other transparent cover is sealed by a seal. This arrangement increases the number of overall structures. The multiple structures also affect the sealing and fixing of the double-layer transparent cover to a certain extent, which has a certain impact on its sealing life. At the same time, the use of multiple-structure seals in a high-amplitude vibration vehicle environment reduces the reliability of the seal compared to a single structure.

[0004] Patent document CN204020588U discloses a double-layer anti-fog transparent cover for automotive instrument panels. The cover comprises a transparent outer cover with an annular flange on its outer wall, a positioning hole in the flange, a transparent inner cover within the outer cover, a vacuum chamber between the end faces of the inner cover and the outer cover, and a seal between the circumferential sidewalls of the inner cover and the outer cover. This cover has no protective structure on the outside and is susceptible to scratches and collision damage.

[0005] Neither of the above two patents has a rubber-like part as a sealing component. The present application can increase the sealing effect by interfering with the rubber seal. Utility Model Content

[0006] In order to solve the above technical problems, the utility model provides an anti-fog window structure for an engineering machinery display.

[0007] The utility model is achieved through the following technical solutions.

[0008] The utility model provides an anti-fog window structure for an engineering machinery display, comprising a housing, a window panel A, a window panel B, a seal, and an instrument display unit. The window panel A and the window panel B are respectively connected to the seal, and the window panel A and the window panel B are connected to the housing through the seal, and the instrument display unit is arranged in the housing.

[0009] Preferably, the window panel A, window panel B, seal and instrument display unit are placed in the inner cavity of the shell, groove A and groove B are provided on the seal, the window panel A is placed in groove A, and the window panel B is placed in groove B.

[0010] Preferably, a protrusion is provided between the groove A and the groove B.

[0011] Preferably, an opening is provided on one side of the shell, and the opening is provided in a trumpet shape.

[0012] Preferably, the width of the opening is smaller than the width of the inner cavity of the housing.

[0013] Preferably, a vacuum layer is provided between the window panel A and the window panel B.

[0014] The beneficial effects of the present invention are:

[0015] This utility model creates a gap between window panels A and B, evacuating the air in the gap to form a vacuum layer. Since heat cannot travel in a vacuum, the vacuum layer acts as a thermal insulator. Consequently, when the temperature difference between the inside and outside of the vehicle changes, the instrument display unit is unaffected by the temperature difference due to the vacuum layer, thereby preventing fogging. Furthermore, the seal provides a buffering effect between window panels A and B, increasing the durability of the structure. This utility model is suitable for instrumentation in construction and agricultural machinery, such as excavators, loaders, tractors, and receivers. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] Figure 1 It is a structural diagram of the utility model;

[0017] In the figure: 1-housing, 11-opening, 12-inner cavity, 2-window panel A, 3-window panel B, 4-sealing member, 41-groove A, 42-groove B, 43-protrusion, 5-instrument display unit, 6-vacuum layer. DETAILED DESCRIPTION

[0018] The technical solution of the present invention is further described below, but the scope of protection claimed is not limited to the described solution.

[0019] Example:

[0020] like Figure 1As shown, an anti-fog window structure for an engineering machinery display includes a housing 1, a window panel A2, a window panel B3, a seal 4 and an instrument display unit 5. The window panel A2 and the window panel B3 are respectively connected to the seal 4, and the window panel A2 and the window panel B3 are connected to the housing 1 through the seal 4. The instrument display unit 5 is arranged in the housing 1.

[0021] The window panel A2, window panel B3, seal 4, and instrument display unit 5 are placed within the inner cavity 12 of the housing 1. The seal 4 is provided with a groove A41 and a groove B42. The window panel A2 is placed in groove A41 for an interference fit, and the window panel B3 is placed in groove B42 for an interference fit. The seal 4 is made of rubber and has both sealing and cushioning properties.

[0022] A protrusion 43 is provided between the groove A41 and the groove B42 so that a vacuum layer 6 can be fixed between the window panel A2 and the window panel B3.

[0023] An opening 11 is provided on one side of the housing 1 , and the opening 11 is horn-shaped, so as to pass through the instrument display unit 5 from the outside. This arrangement allows both sides of the window panel A2 and the window panel B3 to be protected to a certain extent.

[0024] The width of the opening 11 is smaller than the width of the inner cavity 12 of the housing 1 , which facilitates the fixation of the sealing member 4 in the inner cavity 12 .

[0025] A vacuum layer 6 is provided between the window panel A2 and the window panel B3. The vacuum layer 6 is a vacuum layer and plays a role of heat insulation.
