Description

Technical Field

[0001] The utility model relates to the technical field of automobile sealing strip assembly, and more specifically to a hood front sealing strip connection structure. Background Art

[0002] At present, the automotive industry has continuously improved its requirements for appearance, quality, performance, utilization and loading efficiency, and the traditional assembly method of the front hood seal strip and the hood cover plate often adopts a single snap connection. However, this assembly method has some disadvantages. First, in terms of appearance, a single snap connection may not fully meet the fine requirements for the vehicle's appearance, affecting the overall aesthetics; secondly, there are problems with utilization, which may cause gaps or incomplete fit between assembly parts, affecting the sealing effect and vehicle performance; in addition, there are also difficulties in product installation, which may increase the operating cost and time cost of the assembler.

This structural setting can meet the performance requirements and improve the overall sealing effect.

[0009] 3. Reduce the production process of sealing strips: Compared with the traditional snap-on connection method of hood sealing strips, the new structural design can reduce the production process of sealing strips. The manufacturing process of the first front sealing strip and the second front sealing strip is simplified, thereby improving production efficiency and reducing production costs.

[0010] 4. Improve appearance and beautification performance: By eliminating the traditional snap-on connection method, the overall appearance of the middle part of the hood cover is more concise, which increases the beauty of the product.

[0011] 5. Parts can be disassembled and re-used with less damage to the product: The new structural design makes it easier to disassemble and re-use parts, and causes less damage to the product when used repeatedly.

[0012] According to an embodiment of the utility model, the first front sealing strip includes a metal frame, dense rubber and sponge rubber, a portion of the dense rubber wraps the metal frame, and the dense rubber is integrally connected with the foam tube-shaped sponge rubber.

[0013] According to an embodiment of the utility model, the sponge rubber is provided with auxiliary sealing wings; when the front cover sheet metal is closed, the inner surface of the front cover sheet metal contacts the auxiliary sealing wings, thereby improving the waterproof ability of the first front sealing strip and the front cover sheet metal.
