Description

Technical Field

[0001] The invention belongs to the technical field of automobiles, in particular to a design method for a fully covered decorative cover for an engine compartment. Background Art

[0002] As competition in automobile products becomes increasingly fierce, automobile users have higher and higher requirements for the aesthetics of automobile products. Full-coverage decorative covers for engine compartments have become a necessary component for many automobile manufacturers to enhance product competitiveness. However, adding full-coverage decorative covers to the engine compartment will have a certain adverse effect on the convenience of maintenance operations for users, 4S stores or repair shops, and will also increase the cost per vehicle.

[0003] In the prior art, during the design process of the full-coverage decorative cover of the cabin, the engineering design performs the design of the full-coverage decorative cover according to the shape CAS. There is currently no relevant operating method for proposing specific design requirements in the conceptual design stage from the perspectives of maintenance function satisfaction and cost control.

[0004] The main problem with the current technical approach is that the full-coverage decorative cover is dominated by shape. Since there is no concept design at the conceptual stage, there are problems in the design process of the engine full-coverage decorative cover, such as failure to meet the convenience of maintenance, insufficient cost control or increased design iterations. Summary of the invention

[0005] The present invention provides a design method for a full-coverage decorative cover for an engine compartment. The present invention formulates a reasonable design method for a full-coverage decorative cover from the perspectives of maintenance requirements and cost control in the conceptual design stage, thereby solving the maintenance convenience of the engine compartment of a vehicle model equipped with a full-coverage decorative cover.

[0008] Step 1: Count the engine compartment maintenance items, prioritize them according to the full-coverage decorative cover design evaluation model, and formulate the functional structure design concept of the full-coverage decorative cover according to the maintenance item priority;

[0009] Step 2: Develop a conceptual design plan and boundary data for the full-coverage decorative cover, including the block plan, maintenance function structure boundary, support structure, buckle type, and sealing form;

[0010] Step 3: Output the full coverage decoration concept design and boundary data in step 2 to the modeling for CAS surface production;

[0011] Step 4: Conduct compliance check on the CAS surface of the full-coverage decorative cover according to the conceptual design requirements in step 3;

[0012] Step 5: Output the CAS data that meets the design requirements to the parts design professional for 3D data design of the decorative cover parts;

[0013] Step 6: Conduct conformity check on the 3D data of the full-coverage decorative cover parts;

[0014] Step 7: Complete the entire process of designing the full-coverage decorative cover for the cabin.

[0020] The specific calculation method of the importance comprehensive score is:

[0021] Evaluation is conducted on a scale of 1 to 5 based on three dimensions, with 1 representing the lowest importance and 5 representing the highest importance. The comprehensive importance score = user operation * 40% + 4S shop or repair shop operation * 30% + operation frequency * 30%.

[0022] The specific method of step 2 is as follows:

[0023] 21) Collect environmental data of powertrain, cabin sheet metal, and accessories;

[0024] 22) In combination with the process requirements, the maintenance and repair items should formulate a full coverage decorative cover block plan and functional structure plan boundaries;

[0025] 23) Based on the vehicle model positioning, the full coverage decorative cover support structure, buckle type, and sealing form are formulated by benchmarking the technical solutions of competing vehicles;

[0026] 24) Organize steps 21), 22) and 23), compile the conceptual design method of the full-coverage decorative cover and boundary data, and output them.

[0027] In the step 22), the functional structure scheme boundary is formulated according to the full coverage decorative cover block scheme.

[0028] In the step 23), the full coverage decorative cover support structure includes a metal bracket support and a plastic bracket support; the buckle types include exposed plastic buckles, hidden plastic buckles and hidden metal buckles; the sealing forms include a lower rear sealing strip and an upper front + left and right sealing strips.

[0029] The beneficial effects of the present invention are:

[0030] The present invention develops a reasonable design method for the full-coverage decorative cover from the perspectives of maintenance requirements and cost control during the conceptual design stage, thereby solving the maintenance convenience of the engine compartment of a vehicle equipped with a full-coverage decorative cover.
