Description

Technical Field

[0001] The invention belongs to the technical field of sealing, and in particular relates to a sealing device. Background Art

[0002] With the rapid development of new energy vehicles and intelligent driving performance, the demand for multifunctional automobile mounting covers is becoming more and more diverse. The lightweight mounting cover system and the matching structure and sealing performance of the mounting cover and components have become new research directions.

[0003] The sealing structure of the mounting cover assembly in the prior art is relatively complex, such as Figure 7 As shown, the existing installation cover assembly includes a cover body A, a skylight B (glass material) and a sealing mechanism C (plastic material) between the cover body A and the skylight B, wherein the sealing mechanism C includes a sealing frame C1 (installed on the skylight B), a first sealing member C2 (used to seal the cover body A and the skylight B), a second sealing member C3 (used to connect the first sealing member C2 and the water channel C5), a fixing member C4 (bolts and nuts, used to connect the water channel C and the cover body A), the water channel C5 and the third sealing member C6 (used to connect the water channel C and the sealing frame C1), see for details. Figure 7 The first seal C2 is a sealing strip that is adhered to the cover body A around its circumference and forms an interference fit with the sealing surface of the sealing frame C1. The second and third seals C3 and C6 are both indirect seals, resulting in less than ideal sealing effects. Therefore, a water trough C5 is designed to drain water leaking from the first seal C2. Consequently, the existing cover's sealing structure requires high component matching and installation precision, resulting in high component cost and heavy weight. Summary of the Invention

The outer edge of the sealing plate 20 is sealed with the first sealing surface 11. The reinforcing plate 21 is sealed with the sealing boss 12 and the second sealing surface 14 respectively. The reinforcing plate 21 is also fixedly connected to the mounting surface 13. This embodiment realizes a triple sealing connection between the mounting plate and the sealing plate 20 through the combination arrangement of the sealing platform, the sealing plate 20 and the reinforcing plate 21 on the mounting plate, and the cooperation between the three in pairs. On the one hand, the triple sealing connection between the mounting plate and the sealing plate 20 is realized (the first sealing: the outer edge of the sealing plate 20 is sealed with the first sealing surface 11, the second sealing: the sealing connection between the reinforcing plate 21 and the sealing boss 12, the third sealing: the sealing connection between the reinforcing plate 21 and the second sealing surface 14).

[0035] In some embodiments of the present invention, a second sealing ring 23 is provided on the first mounting platform 212; The second sealing ring 23 is interference fit with the second sealing surface 14. The seal here is the third seal of the mounting plate and the sealing plate 20. It further prevents water from penetrating from the first and second seals into the inner side of the sealing platform, further preventing moisture and reducing friction noise.

[0036] In some embodiments of the present invention, the second sealing ring 23 is an integrated annular structure, and its material is a sponge strip.

[0037] In certain embodiments of the present invention, the assembly process of the mounting plate and the sealing plate 20 is as follows: First, assemble the sealing plate 20 and the reinforcing plate 21; Next, select several mounting holes on the mounting surface 13 as positioning holes, align the pre-buried bolts 25 with the mounting holes, and insert them so that the second mounting platform on the reinforcing plate 21 is aligned with the mounting surface 13 to achieve positioning; Finally, assemble the bolts 25 and nuts and tighten them (the order of the bolts 25 is, for example, to install and tighten the diagonal nuts first, and then install the other 6 nuts in sequence) to ensure that the mounting surface 13 is in contact and the sealing structure is sealed intact.
