Detailed Description
It should be noted that, in the present invention, the embodiments and features of the embodiments may be combined with each other without conflict.
The present invention will be described in detail below with reference to the accompanying drawings in conjunction with embodiments.
Example one
The embodiment relates to a sealing structure, which is used for sealing between a fresh air opening of a vehicle air conditioner and a front wall metal plate, wherein an air inlet is formed in the front wall metal plate, the fresh air opening is communicated with the air inlet, and the sealing structure mainly comprises a butt joint part, a heat insulation pad and a sealing body. The abutting part is positioned on the front wall metal plate and arranged around the air inlet, and the abutting part extends towards one side of the fresh air inlet; the heat insulation pad faces the fresh air inlet and is arranged on the front wall metal plate, the part, corresponding to the air inlet, of the heat insulation pad is arranged in a hollow mode, and a thinning part with the thickness reduced is formed close to the air inlet and the heat insulation pad; the sealing body is arranged on the vehicle air conditioner in a ring fresh air opening mode, and the sealing body is abutted against the thinning portion and the abutting portion due to the connection between the vehicle air conditioner and the front wall metal plate.
The seal structure of this embodiment is through setting up butt portion in the front on enclosing the panel beating, can install in the front when enclosing the panel beating at vehicle air conditioner, make the seal simultaneously to support to press in attenuate portion and butt portion on, thereby can form the double-pass sealedly in new trend department, not only can avoid preceding enclosing the panel beating and expose, also can improve the sound insulation performance of here simultaneously, thereby can effectively reduce from this department transmit the cabin noise in the driver's cabin, and then can effectively improve passenger's the travelling comfort of taking, and make seal structure can have better result of use.
An exemplary structure of the sealing structure of the present embodiment based on the above overall structure is shown in fig. 1 to 3, in which the fresh air opening 101 of the vehicular air conditioner 1 of the present embodiment is similar in structure to the related art and is substantially rectangular in shape as shown in fig. 4; the shape of the sealing body 4 follows the shape of the fresh air opening 101, i.e. it is also substantially rectangular. In addition, in order to facilitate the installation of the sealing body 4, the edge of the annular fresh air opening 101 is provided with a flange 202, the sealing body 4 is arranged on the flange 102, and specifically, the sealing body 4 can be adhered to the flange 202. In addition, in order to improve the structural strength of the sealing body 4, the surface of the sealing body 4 of the present embodiment is subjected to a skinning treatment. To improve the sealing effect, the sealing body 4 of the present embodiment may be made of EPDM.
The whole structure of the front wall metal plate 2 of the embodiment is similar to that of the prior art, and as shown in fig. 5, the air inlet 201 on the front wall metal plate 2 is arranged along with the fresh air opening 101, that is, the shape of the air inlet 201 is the same as that of the fresh air opening 101, so as to improve the ventilation effect of the fresh air opening 101. As shown in fig. 5 in combination with fig. 2, the abutting portion is specifically a flange 202 folded along an edge of the air inlet 201 toward the fresh air inlet 101, and the flange 202 is formed by the front wall sheet metal 2 itself.
