Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of exhaust window sealing, and in particular relates to a multi-path damage-proof exhaust window sealing structure. Background Art
[0002] The rear exhaust window of a traditional vehicle adopts a hinged double-door structure. Due to the need to seal the environment inside and outside the vehicle, a sealing strip is arranged around the exhaust window, and the sealing strip is sealed with the vertical plate on the fan volute by extrusion.
[0003] The vertical plate needs to extrude a certain amount of sealing strip to ensure the reliability of the seal, and the ideal sealing position is in the middle of the sealing strip. However, in the actual process of closing the exhaust window, the vertical plate and the side of the sealing strip are pre-contacted, causing the sealing strip to be squeezed by the side. Although the sealing strip is bonded to the exhaust window with adhesive, most of the sealing strips near the hinge on the exhaust window are lifted up, causing the strip to detach from the sealing groove. The vertical plate is in pre-contact with the side of the sealing strip, so that part of the sealing strip is inside the groove and part is outside the groove. The sealing strip is contacted and squeezed with the edge of the sealing groove, causing damage to the sealing strip. Utility Model Content
[0004] The utility model provides a multi-path anti-damage exhaust window sealing structure, and the technical problem to be solved is: during the closing process of the exhaust window, the rubber strip will not be lifted out of the sealing groove, thereby ensuring the integrity of the rubber strip. At the same time, external dust, sand and gravel entering the car must pass through the multi-layer sealing structure, thereby ensuring a clean and tidy environment inside the car.
[0005] In order to solve the above technical problems, the utility model provides a multi-path anti-damage exhaust window sealing structure, which is characterized in that: it includes a vertical plate, a sealing plate, and a sealing strip; the vertical plate is fixedly connected to the sealing plate, the lower end of the sealing strip is an "n"-shaped structure with a built-in skeleton, and the upper end is a "U"-shaped structure. The two sides of the "U"-shaped structure are sheet-like rubber plates, which are used to seal with the end of the vertical plate and the outer surface of the sealing plate.
[0006] Beneficial effects: The utility model can ensure that when the operator closes the exhaust window, the rubber strip is not lifted out of its original position and does not cause damage to the rubber strip, thereby ensuring the integrity of the sealing strip. The multi-path sealing structure ensures a sealed environment inside the vehicle. BRIEF DESCRIPTION OF THE DRAWINGS

[0012] In order to make the purpose, content and advantages of the present invention clearer, the specific implementation methods of the present invention are further described in detail below.
[0013] The utility model proposes a multi-path anti-damage exhaust window sealing structure, comprising a vertical plate 2, a sealing plate 9, and a sealing strip 10; the vertical plate 2 and the sealing plate 9 are integrally fixed on the fan volute;
[0014] The vertical plate 2 and the sealing plate 9 are welded together and welded to the fan vortex casing. The sealing strip 10 is a special-shaped structure made of mixed rubber. The lower end is an "n"-shaped structure with a built-in metal frame that can be put on the exhaust window 1. The upper end is a "U"-shaped structure. The two ends of the "U"-shaped structure are sheet rubber plates, which are used to seal with the end of the vertical plate 2 and the outer surface of the sealing plate 9.
[0015] The hinge end of the exhaust window is hinged to the vehicle body deck.
[0016] When the exhaust window is closed, the upper end "U"-shaped structure of the sealing strip 10 is in contact with the vertical plate 2 in advance. Since the two ends of the "U"-shaped structure are sheet rubber plates with a certain elasticity, the vertical plate 2 will bend the sheet rubber plates and pass over the sheet rubber plates. While passing over the rubber plates, the rubber plates will also return to their original state under the action of their own elasticity. At this time, the exhaust window continues to be closed, and the vertical plate will contact and seal with the sealing strip 10. At the same time, the two ends of the "U"-shaped structure contact with the sealing plate 9 to prevent external dust, sand and gravel from entering the car.
[0017] After the exhaust window is closed, the path for external dust, sand and gravel to enter the car is shown in the figure. The direction of the arrow is the direction of the path. It needs to pass through three sealing checkpoints. The first is the contact seal between the right sheet rubber plate of the sealing strip 10 and the sealing plate 9, the second is the extrusion seal between the vertical plate and the sealing strip, and the third is the contact seal between the left sheet rubber plate of the sealing strip 10 and the sealing plate 9. The multi-path sealing structure increases the difficulty of dust, sand and gravel to enter the car, ensuring a clean and tidy environment inside the car.
[0018] The sealing strip 10 structure is as follows Figure 5 As shown, it is an elastic rubber structure. In the BB cross-sectional view, the upper end is a "U"-shaped structure, the two ends are composed of sheet rubber plates, the middle interior is a circular arc surface convex structure for contact compression, and the lower end is an "n"-shaped structure for installation on the exhaust window, ensuring the firmness of the installation of the sealing strip. In order to further enhance the stability of the installation of the rubber strip, a metal frame is placed inside to maintain its "n"-shaped structure.
[0019] The sealing strip of the utility model has a "U"-shaped structure, the two ends of the "U"-shaped structure are used for contact and sealing with the sealing plate, and the middle of the "U"-shaped structure is used for contact and sealing with the vertical plate, forming a multi-path sealing structure. The sheet structures at both ends of the "U"-shaped structure avoid damage to the rubber strip.
[0020] The combination of the vertical plate and the sealing plate is not limited to welding fixation, and can be fixed by bolts, rivets, etc.
[0021] The sealing strip is not only used for the rear exhaust window, but can also be used for any flip-up door window cover. The middle arc surface of its "U"-shaped structure can be any raised structure, and the internal metal frame of the "n"-shaped structure can be replaced with other fixed structural forms.
[0022] The utility model can ensure that the rubber strip is not lifted out of its original position and damaged when the operator closes the exhaust window, thereby ensuring the integrity of the sealing strip, and the multi-path sealing structure ensures a sealed environment in the vehicle.
[0023] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
