Description

Technical Field

[0001] The present invention relates to the technical field of industrial vehicle cabin sealing, in particular to an industrial vehicle cabin sealing structure. Background Art

[0002] At present, the cabin sealing type used in domestic industrial vehicles is that the four corners of the cabin body are connected with sharp angles. The left side, front side and right side of the cabin body are sealed with a side airbag structure, and the rear side of the cabin body is sealed with a straight airbag structure. The airbag sealing direction needs to be changed from the left side to the rear side. The side airbags and the rear airbags at the left and right corners are spliced ​​with a special size component for sealing, so as to achieve sealing at the corners and connect the airbags into one.

[0003] In the existing technical solution, the airbag is made of two cross-section airbags spliced ​​together. The splicing point is limited by the process means, resulting in poor sealing performance. Moreover, the transition area between the side and rear of the cabin body is affected by the manufacturing accuracy of the matching components. The transition airbag area cannot form an effective and reliable seal, and the seal often fails, causing rainwater to enter the cabin, bringing the risk of electrical failure and short circuit inside the cabin. In addition, after the seal fails, the noise in the cabin leaks out through the holes and gaps, causing noise pollution and affecting the driving experience. Summary of the Invention

[0034] The supporting part includes a left side panel 2, a right side panel 3, a rear sealing panel 4, and a front sealing panel 7. The connection between the rear sealing panel 4 and the left side panel 2 and the right side panel 3 is provided with a rear transition panel 6, and the connection between the front sealing panel 7 and the left side panel 2 and the right side panel 3 is provided with a front transition panel 6. The position where the supporting part contacts the cabin body 1 is provided with a supporting side panel that cooperates with the cabin side panel. The upper ends of the left side panel 2 and the right side panel 3 are bent inward to form a left side panel 21 and a right side panel 31 respectively. The front end of the rear sealing panel 4 is provided with a rear sealing panel side panel 41, and the side of the rear transition panel 5 close to the cabin body 1 is provided with a transition side panel 51. The supporting side panels include the left side panel 21, the right side panel 31, the rear sealing panel side panel 41, the transition side panel 51 and the upper end surfaces of the front sealing panel 7 and the front transition panel 6 that are in contact with the sealing airbag 8.

[0035] The sealing airbag 8 is an annular structure that surrounds the cabin body 1. The sealing airbag 8 includes a groove body 81. A sealing cavity 82 is provided in the groove body 81. The groove body 81 is a U-shaped structure. The sealing cavity 82 is a U-shaped groove with one end open in the groove body 81. A groove frame 83 is provided in the groove body 81. The groove frame 83 is made of metal. The side walls of the sealing cavity 82 are provided with sealing strips 84 on both sides. At least one sealing strip 84 is provided on each side wall. The raised end of the sealing strip 84 is inclined toward the depth of the sealing cavity 82. In this embodiment, two sealing strips 84 are provided on each side. The open end of the sealing cavity 82 is provided with a sealing lip 85. The sealing lip 85 is located near the airbag. On one side of the cavity 86, the sealing lip 85 extends from one end of the groove body 81 to the opening position close to the sealing cavity 82, and the distal end of the sealing lip 85 is an internally hollowed honeycomb structure. An airbag cavity 86 is provided on the side of the groove body 81 close to the supporting side plate. The upper end of the airbag cavity 86 is fixedly connected to the groove body 81, and a protrusion is provided at the end of the airbag cavity 86 away from the groove body 81. The airbag cavity 86 is provided with an airbag wall 88, and at least one air hole 87 is provided on the airbag wall 88.

Since the sealing cavity 82 of the U-shaped structure of the present application is provided with a sealing lip 85 at the opening and a sealing strip 84 in the sealing cavity 82, it can fit closely with the side plates around the cabin body 1 to increase the sealing effect, and then the cabin When the main body 1 is closed, the lower end of the airbag wall 88 of the airbag cavity 86 at the lower end of the sealing airbag 8 is pressed against the side plate of the support part. Under the action of the gravity of the cabin main body 1, the airbag cavity 86 is deformed. Since the airbag wall 88 of the present application is a honeycomb shape with a hollow interior, it is more likely to deform. At the same time, an air hole 87 is provided on the airbag wall, and the gas in the airbag cavity 86 can be slowly discharged through the air hole 87, so that the cabin main body 1 is more fitted with the support part, increasing the sealing performance. At the same time, it can also provide a buffer for the closing of the cabin main body 1 to avoid the cabin main body 1 causing impact on the support part.
