Description

Technical Field

[0001] The present invention belongs to the field of automobile technology, and relates to a method for designing the aesthetics of a passenger car engine compartment, and more specifically, to a method for designing the aesthetics of an engine compartment used in the automobile design process. The method is mainly used to solve the current situation that the arrangement of parts of various systems in the existing engine compartment is messy and the aesthetics is poor. Background Art

[0002] Today, as competition in automobile products becomes increasingly fierce, automobile users have higher and higher requirements for automobile products. The aesthetics of engine compartment fabrics has become a necessary means for many automobile manufacturers to improve product competitiveness. The common solution at this stage is to add a full-coverage decorative cover for the cabin, which is costly and makes maintenance less convenient, and cannot fundamentally solve the problem of poor aesthetics.

[0003] In the existing technology, the cabin layout is designed only from the dimensions of maintenance, layout clearance, heat damage, etc. There is currently no relevant operating method for proposing specific design requirements from the perspective of aesthetics in the data design stage and the actual vehicle verification stage.

[0004] The utility model with announcement number CN211196374U belongs to the field of vehicle technology and relates to the cabin layout structure and vehicle of extended-range electric vehicles. The cabin layout structure of the extended-range electric vehicle includes: a range-extending module, which is arranged in the middle of the front cabin of the vehicle; a high-voltage module, which is arranged on one side of the range-extending module, and the high-voltage module includes an OBC / DCDC two-in-one assembly, a generator controller, a range-extending controller, a high-voltage distribution box, a PTC and a brake assembly; a low-voltage module, which is arranged on the other side of the range-extending module, and the low-voltage module includes a battery, a relay box and an ECU. The utility model can fully and effectively utilize the space in the cabin, improve the utilization rate of the cabin space, and centrally arrange high-voltage devices and low-voltage devices respectively, shorten the high and low voltage connection lines, reduce the cost of the whole vehicle, and reduce the interference effect.

[0005] The retrieved patent is to effectively utilize the space in the cabin through layout and integration, improve the utilization rate of the cabin space, centrally arrange high-voltage devices and low-voltage devices, shorten the high-voltage and low-voltage connection lines, reduce the cost of the whole vehicle, and reduce the effect of interference. This patent mainly improves the aesthetics of the cabin by formulating the cabin aesthetics design method and process, and formulating the evaluation model, which is inconsistent with the research direction of the retrieved patent.

[0006] The patent document with announcement number CN106275086B provides a car cabin assembly, including an upper longitudinal beam and a front subframe located below the upper longitudinal beam, the car cabin assembly also includes an intermediate longitudinal beam and a connecting support portion, the intermediate longitudinal beam is arranged between the upper longitudinal beam and the front subframe, and the connecting support portion is connected to the intermediate longitudinal beam, the upper longitudinal beam and the front subframe. The car cabin assembly provided by the present invention is upgraded to a stable "wood"-shaped structure by adding an intermediate longitudinal beam between the upper longitudinal beam and the front subframe, and connecting the upper longitudinal beam, the intermediate longitudinal beam and the front subframe by using the connecting support portion, so that the vehicle can transmit the collision force through three paths when the vehicle collides at high speed, thereby improving the collision energy absorption effect of the car cabin assembly.

[0007] The retrieved patent increases cabin safety through structural design, allowing the vehicle to transmit collision force through three paths when colliding at high speed, thereby improving the collision energy absorption function of the vehicle cabin assembly. This patent mainly improves the cabin aesthetics by formulating cabin aesthetics design methods and processes, and formulating evaluation models, which is inconsistent with the research direction of the retrieved patent.

[0008] The patent document with the announcement number CN105459784B discloses a car cabin and a car, wherein the car cabin comprises: a powertrain compartment located at the rear side of the car passenger compartment; a rearview glass window assembly installed between the car passenger compartment and the powertrain compartment and isolating the powertrain compartment and the car passenger compartment; and a cabin glass cover assembly covering the space formed by the powertrain compartment and the rearview glass window assembly. The present invention realizes the reuse of the heat generated by the powertrain, and does not require an additional heating device for the car rearview window or rear windshield, thereby solving the problem of fogging of the car rearview window, and reducing the car manufacturing cost due to the addition of a rearview window heating device, while also eliminating the car use cost due to the addition of a rearview window heating device.

[0009] The retrieved patent is used to reuse the heat generated by the powertrain, and there is no need to add additional heating devices to the rearview window or rear windshield of the car, which solves the problem of fogging of the rearview window of the car and reduces the manufacturing cost of the car due to the addition of a rearview window heating device. It also eliminates the cost of using the car due to the addition of a rearview window heating device. This patent mainly improves the aesthetics of the cabin by formulating a cabin aesthetics design method and process, and at the same time formulating an evaluation model, which is inconsistent with the research direction of the retrieved patent.

[0010] In summary: for the extended-range electric vehicle cabin layout structure and vehicle disclosed in Patent Document 1, a car cabin assembly disclosed in Patent Document 2, and a car cabin and car disclosed in Patent Document 3, their research objects, structural principles, and application scopes are completely different from the research field of this patent on a passenger car engine compartment aesthetics design method in the car design process. Summary of the invention

[0031] Furthermore, the said area division of the cabin refers to dividing the cabin into 6 areas, namely R area, P area, C area, E area, L area, and F area.

[0032] Furthermore, the R area is the main engine room oil area, which is mainly arranged with expansion tank, washing liquid tank, oil supply pipeline and air conditioning pipeline;

[0033] The P area is the powertrain area, where the powertrain is mainly arranged;

[0034] The C area is the central area of ​​the cabin, where the engine decorative cover, some sensors, and solenoid valve components are mainly arranged. The P area and the C area can be interchanged due to the difference in the position of the exhaust;

[0035] The E area is the cabin electrical system area, which mainly arranges batteries and distribution box electrical components.
