Description

Technical Field

[0001] The utility model relates to the fields of automobile interior sealing, sound insulation and engine hood protection, and in particular to a foam assembly structure of an automobile ventilation cover plate. Background Art

[0002] In the prior art, there are generally two ways to install EVA foam at the automobile ventilation cover.

[0003] One is with installation points. The standard parts are embedded in the EVA foam and foamed together, which results in the need to thicken the overall volume to ensure that the standard parts are not easily damaged and fall off, increasing the cost of this part. During assembly, the standard parts are clamped into the sheet metal and fixed, and a separate material rack is required for transportation to prevent the standard parts from falling off. During disassembly, the standard parts are easily separated from the parts, causing damage to the parts.

[0004] The other is the snap-in type (no mounting point). The sheet metal needs to be made into a deeper feature groove. The EVA foam is fixed by the stepped feature limit. Disadvantages: The sheet metal is not easy to design and produce, which increases the complexity of mold design. This EVA foam is not hard fixed, and it is easy to be misplaced over time, resulting in poor sealing and sound insulation effects, and a poor driver experience in the cab. Summary of the invention

[0005] The technical problem to be solved by the utility model is to provide a foam assembly structure of an automobile ventilation cover plate in view of the above-mentioned deficiencies.

[0006] The utility model is realized by the following technical solutions:

[0007] A foam assembly structure for an automobile ventilation cover comprises an assembly structure body, a plurality of mounting buckles and a plurality of sealing strip lap parts; the plurality of mounting buckles and the plurality of sealing strip lap parts are connected to the assembly structure body and have three mutually perpendicular installation directions.

[0008] Furthermore, in the foam assembly structure of the automobile ventilation cover, the assembly structure main body, the plurality of mounting buckles and the plurality of sealing strip lap parts are EVA foam one-piece molded assembly structures.

[0009] Furthermore, in the foam assembly structure of the automobile ventilation cover, the mounting buckle is in an outward-facing O-shaped shape extending from an end away from the main body of the assembly structure to an end close to the main body of the assembly structure.

[0010] Furthermore, in the foam assembly structure of the automobile ventilation cover, the number of the mounting buckles is 2 and they have the same mounting direction.

[0011] Furthermore, in the foam assembly structure of the automobile ventilation cover, the number of the sealing strip overlap parts is 2, and they have mutually perpendicular installation directions, and also have mutually perpendicular installation directions with the installation buckles.

[0012] The advantages and effects of the utility model are:

[0013] The assembly structure main body, installation buckle and sealing strip lap parts of the utility model provided by the present application are an integrated EVA foam molded assembly structure, which is easy to clip during installation and has better stretchability. The sheet metal clip joints are wrapped more tightly, the clip joints are firm, the clip joints are sealed, and the sound insulation is better. The volume of the entire part is reduced, and no other standard parts need to be embedded, the cost is low, and there will be no misalignment. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] Figures 1 to 4 The schematic diagram of the structure of the foam assembly structure provided by the utility model is shown. The foam assembly structure comprises an assembly structure body 1, a plurality of mounting buckles and a plurality of sealing strip lap parts. The plurality of mounting buckles and the plurality of sealing strip lap parts are connected to the assembly structure body 1 and have three mutually perpendicular mounting directions, which are used to stably fix the foam assembly structure in the automobile ventilating cover from three directions.

[0023] like Figure 5As shown, in one embodiment, the assembly structure body 1, a plurality of mounting buckles and a plurality of sealing strip lap parts are an integrally formed EVA foam assembly structure. The number of mounting buckles is 2, namely the first mounting buckle 2 and the second mounting buckle 21, and they have the same installation direction, that is, the two mounting buckles are located on the same surface of the assembly structure body 1. The number of sealing strip lap parts is 2, namely the first sealing strip lap part 3 and the second sealing strip lap part 31, and they have mutually perpendicular installation directions, and have mutually perpendicular installation directions with the mounting buckles (the first mounting buckle 2 and the second mounting buckle 21), that is, the mounting buckles, the first mounting buckle 2 and the second mounting buckle 21 are respectively located on mutually perpendicular surfaces of the assembly structure body 1. Further, the mounting buckle is an outer eight-shaped shape extending from the end away from the assembly structure body to the end close to the assembly structure body. Compared with the prior art, the foam assembly structure provided by the utility model shortens the production cycle of parts and improves production efficiency. It reduces the material cost by 15%, improves the sealing and sound insulation, and is firm and convenient to install. It is easy to disassemble and not easy to damage, and reduces loss. The impact of vibration on other parts of the vehicle is reduced, which helps to maintain the stability and ride comfort of the vehicle.
