DETAILED DESCRIPTION

[0036] The preferred embodiments of the present application will be described below with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are only used to explain the technical principles of the present application, and are not intended to limit the protection scope of the present application.

[0037] It should be noted that in the description of the present application, the terms "inner", "outer" and the like indicating the direction or positional relationship are based on the direction or positional relationship shown in the drawings, which is only for the convenience of description, and does not indicate or imply that the device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present application. In addition, the terms "first", "second" are only for descriptive purposes, and cannot be understood as indicating or implying relative importance.

[0038] In addition, it should also be noted that in the description of the present application, unless otherwise explicitly specified and limited, the terms "provided", "connected", "mounted" should be understood broadly, for example, it can be fixedly connected, or it can be detachably connected, or it can be integrally connected. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0039] Based on the background technology, the sealing and sound insulation of the connection between the air conditioner of the existing vehicle and the front panel are not ideal, which affects the comfort and safety of the vehicle. The present application provides a sealing assembly of a vehicle and a vehicle, which aims to tightly fit a sponge sealing plate between an air conditioner box and a front panel, as well as a first sealing ring, a second sealing ring and a sealing gasket, the first sealing ring and the sealing gasket are integrally formed, the first sealing ring is tightly fitted between the air conditioner pipeline and the pipeline through hole, the second sealing ring is tightly fitted around the bolt through hole, and the sealing gasket is tightly fitted between the air conditioner box and the sealing plate, thereby forming a tight sealing structure to isolate water flow and noise.

[0040] Exemplarily, similar to the household air conditioner which is composed of two parts of indoor unit and outdoor unit, the vehicle air conditioner also includes two parts, which are an evaporating box installed in the cabin and a compressor, a condenser and a throttle valve installed outside the cabin (usually installed in the engine compartment), and the two parts are connected into a circulating heat exchange system through high and low pressure pipelines.

[0041] As shown in Figure 1 The cabin and the engine compartment are separated by the front panel 1, the evaporating box (air conditioner box 2) is usually installed on the inner side of the front panel 1, i.e. on the side inside the cabin, and is fixed by tightening the bolts, and first pipeline through hole 11 and bolt through hole 12 are reserved at the positions where the front panel 1 and the air conditioner box 2 are fitted, respectively, to provide various high and low pressure pipelines and installation bolts to pass through.

[0042] Due to the machining and assembly tolerances, there will inevitably be gaps between the air conditioning box 2 and the front wall panel 1, and there will also be gaps between the air conditioning pipeline and the first pipeline through hole 11 and between the bolt and the bolt through hole 12, so that the water flow, dust and noise in the engine compartment can enter the cabin through these gaps, seriously affecting the sealing and quietness of the cabin.

[0043] Therefore, it is necessary to seal these parts, and the existing processing method is to attach a large area of sponge between the air conditioning box 2 and the front wall panel 1, and to improve the fit between the two by compressing the sponge to complete the sealing of the gaps. However, the sealing effect of the sponge is limited, and it cannot block the gaps in the first pipeline through hole 11 and the bolt through hole 12, so that water flow and noise can still enter the cabin, affecting the waterproof and sound insulation effect.

[0044] In view of the above problems, as shown in Figures 1 to 4 The sealing assembly 3 comprises a sealing plate 31 and a sealing gasket 32, and the sealing plate 31 and the sealing gasket 32 are tightly attached and pressed between the front wall panel 1 and the air conditioning box 2. The sealing plate 31 is located on the side close to the front wall panel 1, and the sealing gasket 32 is located on the side close to the air conditioning box 2, so that the other side of the sealing plate 31 is tightly attached to the front wall panel 1, and the other side of the sealing gasket 32 is tightly attached to the air conditioning box 2.

[0045] The sealing plate 31 is provided with a second pipeline through hole 312, and the first pipeline through hole 11 and the second pipeline through hole 312 coincide after assembly to allow the air conditioning pipeline to pass through. The first sealing ring 33 is provided on the sealing gasket 32 at positions corresponding to the first pipeline through hole 11 and the second pipeline through hole 312, and the first sealing ring 33 is integrally formed with the sealing gasket 32 and extends into the first pipeline through hole 11 and the second pipeline through hole 312. The outer edge of the first sealing ring 33 is tightly attached to the inner edge of the first pipeline through hole 11 and the second pipeline through hole 312, and the inner edge of the first sealing ring 33 forms a plurality of small sealing holes 331 to adapt to air conditioning pipelines of different shapes and sizes, so that the inner edge of each sealing hole 331 is tightly attached to the outer wall of the corresponding air conditioning pipeline, ensuring the sealing between each pipeline and the pipeline through hole.

[0046] Further preferably, as shown in Figure 4 The first sealing ring 33 is further provided with an annular groove 332 surrounding the sealing hole 331, and the annular groove 332 can form a first layer of resistance to the water flow around the air conditioning pipeline through the resistance and flow guiding effect of the annular groove 332, so as to weaken the impact of the water flow on the sealing hole 331 and reduce the risk of leakage.

[0047] Therefore, by sealing the overlapping surfaces of the air conditioner box 2 and the front wall panel 1 with the sealing plate 31 and the sealing gasket 32 respectively, the two overlapping surfaces can be prevented from directly contacting each other to form a gap due to machining and assembly tolerances, thereby preventing water flow and noise from entering through the gap; the first sealing ring 33 can fill the fitting gap between the air conditioner pipeline and the first pipeline through-hole 11 and / or the second pipeline through-hole 312, so that they form an interference fit to prevent water flow and noise from entering through the pipeline through-hole, effectively supplementing the sealing plate 31 and further improving the sealing and quietness of the cabin.

[0048] It should be noted that the material, thickness, density and elasticity of the sealing plate 31 and the sealing gasket 32 are different. The sealing plate 31 is softer, thicker, less dense and more elastic than the sealing gasket 32. In this application, the sealing plate 31 is preferably made of PU sponge, and the sealing gasket 32 is preferably made of EPDM rubber. This arrangement forms two sealing layers of different materials and densities between the air conditioner box 2 and the front wall panel 1. The combination of PU sponge and EPDM rubber can ensure that the sealing layer closely fits between the air conditioner box 2 and the front wall panel 1, improving the sealing performance, and also allows the sealing layer to have some elasticity after being compressed, so as to better absorb vibrations and reduce noise.

[0049] Further preferably, a waterproof film (not shown in the figure) is also provided on the fitting surface of the sealing block and the front wall panel 1, which can effectively prevent water from penetrating and ensure the elasticity of the sponge, so that the sealing plate 31 has the functions of shock absorption, sound insulation and waterproofing.

[0050] In addition, as shown in Figure 2 、 Figure 5 and Figure 6 , the sealing assembly 3 of the utility model further comprises a second sealing ring 34 surrounding the bolt through-hole 12, and the second sealing ring 34 closely fits between the front wall panel 1 and the air conditioner box 2. Part of the second sealing ring 34 is embedded in the air conditioner box 2, and the other part of the second sealing ring 34 is located between the air conditioner box 2 and the front wall panel 1. Thus, the surrounding of the bolt through-hole 12 can be sealed to prevent water flow and noise from spreading around the bolt through-hole 12 and entering the cabin, further improving the overall sealing performance of the vehicle.

[0051] It should be noted that in actual application, those skilled in the art can flexibly set the second sealing ring 34 to be made of sponge, rubber or other elastic waterproof materials, as long as it can prevent water flow from spreading around the bolt through-hole 12. Such flexible adjustment and change do not deviate from the principles and scope of the utility model, and should be limited within the protection scope of the utility model. The utility model preferably sets the second sealing ring 34 to be made of PU sponge, and a waterproof film is provided on the fitting surface of the second sealing ring 34 and the front wall panel 1.

[0052] Preferably, as shown in Figure 5 and Figure 6 The second sealing ring 34 is fixed on the air conditioning box 2, and an annular mounting groove 21 is arranged on the outer shell of the air conditioning box 2, the size of the mounting groove 21 is matched with the second sealing ring 34, and the second sealing ring 34 can be just accommodated in the mounting groove 21. One side of the second sealing ring 34 is fixed in the mounting groove 21 by gluing, and the depth of the mounting groove 21 is preferably set to half of the thickness of the second sealing ring 34, so that when the air conditioning box 2 is tightly fastened and attached to the front wall panel 1 by the fastening bolt, the thickness of the second sealing ring 34 is compressed to 50% of the original thickness.

[0053] In this way, the second sealing gasket 32 still has a certain compression and rebound allowance, which not only ensures the close attachment of the second sealing gasket 32 to the air conditioning box 2 and the front wall panel 1, prevents the second sealing gasket 32 from losing elasticity or deforming to affect the sealing performance after being compressed, but also avoids forming a hard connection between the air conditioning box 2 and the front wall panel 1 to reduce the transmission of vibration and noise.

[0054] In addition, the vehicle provided by the utility model further has the technical effects of the sealing assembly, and compared with the vehicle before the improvement, the sealing performance and the quietness of the cabin of the vehicle of the utility model are greatly improved, and the comfort and the safety of the vehicle are improved.

[0055] Thus, the technical scheme of the utility model has been described in combination with the preferred embodiments shown in the drawings, but it is easy for those skilled in the art to understand that the protection scope of the utility model is obviously not limited to these specific embodiments. Those skilled in the art can make equivalent changes or replacements to the related technical features without departing from the principles of the utility model, and the technical schemes after the changes or replacements will all fall within the protection scope of the utility model.
