Description

Technical Field

[0001] The present application relates to the field of vehicle technology, and in particular to a method, device, vehicle and storage medium for designing vehicle interior decoration parts. Background Art

[0002] With the rapid development of the automobile industry and the improvement of people's living standards, cars have become an indispensable part of people's daily lives. However, when a car is driving, especially when driving at high speeds or when the road conditions are poor, a lot of noise will be generated. These noises mainly come from the operation of the car engine, wind resistance, friction between the tires and the road, and vibration inside the vehicle. Among them, low-frequency noise is easy to interfere with passengers due to its long wavelength and strong penetration ability, affecting the driving experience and riding comfort.

[0003] In the related technologies, noise control technology can be divided into two methods: active noise reduction and passive noise reduction. Traditional interior decoration parts usually participate in the passive noise reduction process of passenger cars through sound absorption and sound insulation methods. The commonly used sound insulation and sound absorption methods are to add some sound insulation or sound absorption materials to isolate the sound source from the surrounding environment so that the radiated noise cannot be directly transmitted to the surrounding area, thereby achieving the purpose of noise control.

[0004] However, the above measures all require a certain amount of mass and space to implement. With the lightweight trend of passenger car development and the need to maximize passenger space, traditional sound insulation and sound absorption methods are difficult to implement in certain key locations. In addition, the working frequencies of existing sound absorption and sound insulation materials are mostly concentrated in the mid- and high-frequency bands. There is currently a lack of effective solutions for low-frequency problems, which need to be solved urgently. Summary of the invention

[0049] Embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present application, and should not be construed as limiting the present application.

[0050] The following describes the vehicle interior decoration design method, device, vehicle and storage medium of the embodiment of the present application with reference to the accompanying drawings. In view of the problems of increasing mass and occupying space and difficulty in effectively absorbing low-frequency noise mentioned in the above background technology, the present application provides a vehicle interior decoration design method, which improves the existing passenger car interior decoration to enable it to absorb low-frequency sound waves without affecting its original performance.

[0051] Specifically, Figure 1 A schematic flow chart of a method for designing interior vehicle decoration parts provided in an embodiment of the present application.

[0052] like Figure 1As shown, the vehicle interior decoration design method includes the following steps:

[0053] In step S101 , a prediction model of the surface material and acoustic parameters of the vehicle interior decoration parts is constructed.

[0054] Furthermore, in some embodiments, a prediction model for the surface materials and acoustic parameters of vehicle interior decoration parts is constructed, including: obtaining a variety of surface composite porous material samples; measuring the acoustic parameters of each surface composite porous material sample to obtain the acoustic parameters of each surface composite porous material sample; and constructing a prediction model for the surface materials and acoustic parameters of vehicle interior decoration parts based on each surface composite porous material sample and the acoustic parameters of each surface composite porous material sample.

[0055] The acoustic parameter includes at least one of specific impedance, acoustic impedance and sound absorption coefficient.

[0056] Specifically, the embodiments of the present application can select a variety of surface composite porous materials with different physical properties as samples, for example, fiber materials (such as glass fiber, carbon fiber, plant fiber, etc.), foam materials (such as polyurethane foam, polyethylene foam, etc.), fabric materials (such as non-woven fabrics, knitted fabrics, etc.) and other new composite materials (such as nanoporous materials, microporous plastics, etc.).

[0057] Furthermore, an acoustic testing instrument is used to accurately measure and analyze the acoustic parameters of each surface composite porous material sample to obtain the specific impedance, acoustic impedance, sound absorption coefficient and other related acoustic parameters of each surface composite porous material sample.

[0058] Furthermore, through statistical analysis and machine learning algorithms, a mathematical relationship between material samples and acoustic performance is established, and a prediction model of the surface material and acoustic parameters of vehicle interior decoration parts is constructed based on each surface composite porous material sample and its corresponding acoustic parameters.

[0059] In step S102, the target noise reduction requirement of the current vehicle is obtained, and based on the target noise reduction requirement, the prediction model is used to predict the acoustic parameters of the surface material to obtain the prediction result of the acoustic parameters of the surface material.

[0060] Specifically, the embodiments of the present application can test the sound field at the location of each decorative part in the vehicle, clarify the main frequency band and demand target of noise reduction, and input the set noise reduction target into the prediction model. For example, if the target noise reduction requirement is to reduce the noise by 8dB in the 50-200Hz frequency band, the prediction model will calculate the acoustic parameters of the required surface materials based on the target noise reduction requirement. The acoustic parameters can be used to guide the selection and design of surface materials.

[0061] In step S103, the surface material of the interior decoration of the current vehicle is selected according to the prediction result of the surface material acoustic parameters, the target surface material of the interior decoration is obtained, and the design structure of the resonator is determined according to the spatial position of the interior decoration and the target noise reduction requirement.

[0062] Specifically, the prediction model is used to predict the acoustic parameters of the surface material and select the target surface material that meets the target noise reduction requirements. In addition, the embodiment of the present application can also adjust the specific impedance of the composite material on the surface of the interior decoration part to change the surface acoustic impedance and sound absorption coefficient of the interior decoration part, thereby realizing the construction of the sound absorption structure at the material level of the interior decoration part.

[0063] Furthermore, according to the design principle of the Helmholtz resonator, combined with the actual in-vehicle installation position of the interior decoration parts, the in-vehicle acoustic cavity feedback and the target noise reduction requirements, the design of the Helmholtz resonator structure is determined by improving the structure of the interior decoration parts.

[0064] In step S104, the interior decoration of the current vehicle is designed and manufactured according to the target surface material of the interior decoration and the design structure of the resonator.

[0065] Specifically, by combining the design of the surface acoustic materials of the vehicle interior decoration parts with the design of the internal resonator structure, the vehicle interior decoration parts are manufactured to achieve sound absorption and noise reduction for noises of different frequencies.

[0066] For example, the embodiment of the present application takes the vehicle roof decoration as an example, and the final design and production effect can be as follows: Figure 2 shown.

[0067] Furthermore, in some embodiments, after the interior decoration of the current vehicle is designed and manufactured according to the target surface material of the interior decoration and the design structure of the resonator, it also includes: performing actual vehicle verification on the completed interior decoration to obtain a verification result; judging whether the verification result meets a preset verification condition; if the verification result does not meet the preset verification condition, re-executing the step of predicting the acoustic parameters of the surface material using the prediction model until the verification result meets the preset verification condition.

[0068] Furthermore, in some embodiments, after determining whether the verification result satisfies the preset verification condition, the method further includes: if the verification result satisfies the preset verification condition, saving the target surface material of the current vehicle interior decoration part and the design structure of the resonator.

[0069] Specifically, the finished interior decoration parts are installed on the target vehicle, and under the preset test environment, professional acoustic testing equipment is used to accurately measure the sound field at the location of each interior decoration part. The collected sound field data is compared with the baseline data when the decoration parts are not installed to evaluate the noise reduction effect of the decoration parts, that is, to verify the results.

[0070] The noise reduction effect obtained from the actual vehicle verification is compared with the preset verification conditions to determine whether it meets the requirements. If the noise reduction effects in all frequency bands reach or exceed the preset targets, the verification results are judged to meet the preset verification conditions, and the target surface material of the current interior trim and the design structure of the resonator are saved for subsequent mass production preparation.

[0071] Furthermore, if the verification result does not meet the preset verification conditions, the reason may be that the sound absorption performance of the currently used surface composite porous material is insufficient and cannot effectively absorb noise in a specific frequency band, or the structural design of the resonator fails to effectively capture and attenuate the sound waves in the target frequency band, resulting in unsatisfactory noise reduction effect. At this time, the prediction model is used to re-screen suitable surface composite porous materials, adjust their physical properties to improve their sound absorption performance, and adjust the geometric dimensions, cavity volume, opening area and other parameters of the resonator according to the Helmholtz resonator principle to make it more effective in capturing and attenuating the sound waves in the target frequency band.

[0072] Furthermore, after the above optimization is completed, the improved interior decoration parts are remade and installed, and the actual vehicle verification is performed again. The above verification steps are repeated until the verification results meet the preset verification conditions.

[0073] Therefore, the embodiment of the present application verifies the interior decoration parts on a real vehicle and optimizes the design of the noise reduction effect until the design goal is achieved, thereby ensuring the sound absorption and noise reduction effect.

[0074] In order to facilitate those skilled in the art to more clearly and intuitively understand the vehicle interior decoration design method proposed in this application, Figure 3 Provide detailed explanation.

[0075] like Figure 3 As shown, the vehicle interior decoration design method includes the following steps:

[0076] S301, start.

[0077] S302, confirming the status of the sample vehicle.

[0078] S303, test and analysis of the sound field status of interior decoration parts.

[0079] S304, formulate technical requirements for acoustics of vehicle interior trim parts.

[0080] S305, interior design.

[0081] S3051, Surface Acoustic Material Selection.

[0082] S3052, Acoustic Structural Design.

[0083] S306, determine whether the performance of the interior trim meets the acceptance conditions, if yes, execute S307, otherwise, execute S305.

[0084] S307, design freeze.

[0085] Therefore, the embodiment of the present application adopts the original vehicle interior decoration parts as the carrier, and improves the acoustic performance of the vehicle interior decoration parts while retaining the original functional characteristics by changing the acoustic sound absorption structure of the surface material of the parts, combining the installation position of the interior decoration parts and the internal cavity structure design, especially increasing the sound absorption capacity in the low frequency band, providing a new component design method for improving the noise level in the car, changing the acoustic performance characteristics of traditional vehicle interior decoration parts, and while effectively improving the noise level in the car, reducing the development cost of the vehicle interior noise control, and reducing the increase in weight and occupied space caused by the vehicle interior noise control.

[0086] According to the vehicle interior decoration design method proposed in the embodiment of the present application, based on the target noise reduction requirements, the prediction model is used to predict the acoustic parameters of the surface material, the surface material acoustic parameter prediction results are obtained, and the surface material of the vehicle interior decoration of the current vehicle is selected to obtain the target surface material of the vehicle interior decoration, and the design structure of the resonator is determined according to the spatial position of the vehicle interior decoration and the target noise reduction requirements; according to the target surface material of the vehicle interior decoration and the design structure of the resonator, the vehicle interior decoration of the current vehicle is designed and manufactured. In this way, the problems of the prior art of increasing mass and occupying space and being difficult to effectively absorb low-frequency noise are solved, and a new solution is provided for reducing the noise in the vehicle. By changing the traditional acoustic processing method of the vehicle interior decoration, the cost of a single vehicle and the performance development cycle can be effectively reduced, and the noise reduction performance of the whole vehicle can be improved.

[0087] Next, the vehicle interior decoration design device proposed according to the embodiment of the present application is described with reference to the accompanying drawings.

[0088] Figure 4 It is a block diagram of a vehicle interior decoration design device according to an embodiment of the present application.

[0089] like Figure 4 As shown, the vehicle interior decoration design device 10 includes: a construction module 100, a prediction module 200, a processing module 300 and a design and production module 400.

[0090] Among them, the construction module 100 is used to construct a prediction model for the surface material and acoustic parameters of the vehicle interior decoration parts; the prediction module 200 is used to obtain the target noise reduction requirements of the current vehicle, and based on the target noise reduction requirements, use the prediction model to predict the acoustic parameters of the surface materials to obtain the prediction results of the acoustic parameters of the surface materials; the processing module 300 is used to select the surface materials of the interior decoration parts of the current vehicle according to the prediction results of the acoustic parameters of the surface materials, obtain the target surface materials of the interior decoration parts, and determine the design structure of the resonator according to the spatial position of the interior decoration parts and the target noise reduction requirements; the design and production module 400 is used to design and produce the interior decoration parts of the current vehicle according to the target surface materials of the interior decoration parts and the design structure of the resonator.

[0091] Furthermore, in some embodiments, after the interior decoration of the current vehicle is designed and manufactured according to the target surface material of the interior decoration and the design structure of the resonator, the design and manufacturing module 400 is also used to: perform actual vehicle verification on the completed interior decoration to obtain a verification result; determine whether the verification result meets a preset verification condition; if the verification result does not meet the preset verification condition, re-execute the step of predicting the acoustic parameters of the surface material using the prediction model until the verification result meets the preset verification condition.

[0092] Furthermore, in some embodiments, after determining whether the verification result satisfies the preset verification conditions, the design and production module 400 is further used to: if the verification result satisfies the preset verification conditions, save the target surface material of the current vehicle interior decoration and the design structure of the resonator.

[0093] Furthermore, in some embodiments, a prediction model 200 for the surface materials and acoustic parameters of vehicle interior decoration parts is constructed, including: obtaining a plurality of surface composite porous material samples; measuring the acoustic parameters of each surface composite porous material sample to obtain the acoustic parameters of each surface composite porous material sample; and constructing a prediction model for the surface materials and acoustic parameters of vehicle interior decoration parts based on each surface composite porous material sample and the acoustic parameters of each surface composite porous material sample.

[0094] Further, in some embodiments, the acoustic parameter includes at least one of specific impedance, acoustic impedance and sound absorption coefficient.

[0095] It should be noted that the above explanation of the embodiment of the vehicle interior decoration design method is also applicable to the vehicle interior decoration design device of this embodiment, and will not be repeated here.

[0096] The in-vehicle trim design device proposed according to the embodiments of the present application, based on the target noise reduction requirement, uses a prediction model to predict the acoustic parameters of the surface material, obtains the prediction result of the acoustic parameters of the surface material, and selects the surface material of the in-vehicle trim of the current vehicle to obtain the target surface material of the in-vehicle trim. The design structure of the resonator is determined according to the spatial position where the in-vehicle trim is located and the target noise reduction requirement; according to the target surface material of the in-vehicle trim and the design structure of the resonator, the in-vehicle trim of the current vehicle is designed and manufactured. Thus, by improving the acoustic performance materials and the internal resonance structure design of the in-vehicle trim, the problems of increasing mass, occupying space, and being difficult to effectively absorb low-frequency noise in the prior art are solved, and at the same time, the cost is reduced and the development cycle is shortened.
