Further, the air conditioner crimping piece is in the shape of a ring, and the air duct crimping piece is in the shape of a ring, so that the sealing performance is good.

Further, the cross-section of the air-conditioning crimping piece is U-shaped, and the cross-section of the air duct crimping piece is an inverted U-shape. With this structure, not only the air conditioner crimping parts and the air duct crimping parts have high strength, but also the air conditioner sealing rubber strip and the air duct sealing rubber strip are conveniently clamped.

Further, it also includes an air duct housing and a support, and an air duct sealing rubber strip is provided between the air duct housing and the air duct crimping parts; at the bottom of the roof, there are slides on both sides of the air duct housing. The slide rail is provided with a chute, the support is provided with a long hole, and the long hole passes through a bolt, and the head of the bolt is located in the chute, and the support is installed on both sides of the air duct shell. The support is provided with an oblong hole, which is convenient for left and right fine-tuning after the air duct shell is installed. The hoisting method of the air duct shell adopts the way of the chute, which is convenient for fine adjustment of the air duct shell moving back and forth.

detailed description

The utility model will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

As shown in FIGS. 1 to 4 , the air duct sealing crimping structure for a vehicle includes a roof 1 , an air conditioner crimping part 2 , and an air duct crimping part 3 .

An air port 11 is provided on the roof 1 .

The air conditioner crimping part 2 is welded outside the tuyere 11 on the top surface of the roof 1, the air conditioner crimping part 2 is in the shape of a ring, and the air conditioner crimping part 2 is provided with an air conditioner crimping groove 21 for The air conditioner sealing strip is clamped. After the air conditioner is installed, the seal between the air conditioner and the roof is realized through the air conditioner sealing strip. This structure is convenient for positioning and limiting the air conditioner sealing strip, and it is convenient to install the air conditioner sealing strip. , It can also effectively prevent the displacement of the air-conditioning sealing strip and affect the sealing performance. The cross-section of the air-conditioning crimping part 2 is U-shaped, so that not only the strength of the air-conditioning crimping part 2 is high, but also the air-conditioning sealing strip is conveniently clamped.

The air duct crimping piece 3 is welded outside the air outlet 11 on the bottom surface of the roof 1 . The air duct crimping part 3 is in the shape of a ring, and the air duct crimping part 3 is provided with an air duct crimping groove 31 for clamping the air duct sealing strip 6. After the air duct housing 4 is installed, pass The air duct sealing strip 6 realizes the sealing between the air duct housing 4 and the roof. This structure facilitates the positioning and positioning of the air duct sealing strip 6, facilitates the installation of the air duct sealing strip 6, and can also effectively To prevent the air duct sealing strip 6 from shifting and affecting the sealing performance. The section of the air duct crimping part 3 is inverted U-shaped, so that not only the strength of the air duct crimping part 3 is high, but also the air duct sealing strip 6 is conveniently clamped.
