[0003] In related technologies, the rear wing is a key component that influences aerodynamic performance. Therefore, during the automotive manufacturing process, especially during the model development phase, the rear wing's structure and design often require repeated changes and redesigns. Furthermore, once the rear wing structure has been finalized, aerodynamic testing is required to obtain test data from a car model's rear wing to determine whether the aerodynamic performance meets the requirements. Specifically, once the design is finalized, a complete car model is constructed using that design for aerodynamic testing, and the model components cannot be modified. When test data for a different rear wing angle is needed, a new car model must be constructed for testing. Changes to the rear wing design cannot be made individually, requiring the re-production of a new car model for testing, which wastes time and increases costs.

[0053] The present application is further described below in conjunction with the accompanying drawings and specific embodiments. The described embodiments should not be considered as limiting the present application. All other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0054] In the following description, reference is made to “some embodiments”, which describes a subset of all possible embodiments, but it will be understood that “some embodiments” may be the same subset or different subsets of all possible embodiments and may be combined with each other without conflict.

[0055] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which this application pertains. The terms used herein are for the purpose of describing the embodiments of this application only and are not intended to limit this application.

[0056] Cars are an important means of transportation today, bringing great convenience to people's lives and work. With the development of automobile technology, people's requirements for cars are getting higher and higher.

[0057] In related technologies, the rear wing is a key component that influences aerodynamic performance. Therefore, during the automotive manufacturing process, especially during the model development phase, the rear wing's structure and design often require repeated changes and redesigns. Furthermore, once the rear wing structure has been finalized, aerodynamic testing is required to obtain test data from a car model's rear wing to determine whether the aerodynamic performance meets the requirements. Specifically, once the design is finalized, a complete car model is constructed using that design for aerodynamic testing, and the model components cannot be modified. When test data for a different rear wing angle is needed, a new car model must be constructed for testing. Changes to the rear wing design cannot be made individually, requiring the re-production of a new car model for testing, which wastes time and increases costs.

[0058] In view of this, a method for obtaining test data of a car model's rear wing is provided in an embodiment of the present application. This method can use an upper cover plate to act as a rear wing, and its angle is adjustable. Only one upper cover plate model needs to be made to obtain aerodynamic data at different rear wing angles, which can greatly improve the convenience of obtaining aerodynamic data and reduce the design cost of the car; and during the test process, timely feedback on the stress conditions at various rear wing angles can facilitate designers to adjust the car shape according to the car model stress data, which is conducive to improving the design and production efficiency of the car.

[0059] Figure 1 This is a schematic diagram of the implementation environment of a method for obtaining test data of a car model tail wing provided in an embodiment of the present application. Figure 1The hardware and software components of this implementation environment primarily include a vehicle 101 and a server 102, with vehicle 101 communicating with server 102. The method for acquiring vehicle model tail wing test data can be executed locally on vehicle 101 or based on interaction between vehicle 101 and server 102. The specific method can be appropriately selected based on actual application circumstances and is not specifically limited in this embodiment.

[0060] The server 102 may be an independent physical server, a server cluster or distributed system composed of multiple physical servers, or a cloud server that provides basic cloud computing services such as cloud services, cloud databases, cloud computing, cloud functions, cloud storage, network services, cloud communications, middleware services, domain name services, security services, CDN (Content Delivery Network), and big data and artificial intelligence platforms. A communication connection may be established between the vehicle 101 and the server 102 via a wireless network or a wired network that uses standard communication technologies and / or protocols. The network may be the Internet or any other network, such as, but not limited to, a local area network (LAN), a metropolitan area network (MAN), a wide area network (WAN), a mobile, wired or wireless network, a private network, or any combination of a virtual private network.

[0061] It should be noted that the method for obtaining test data for a car model rear wing in the embodiment of this application is based on the adjustment structure. Therefore, before describing the method for obtaining test data for a car model rear wing provided in this application, the components of the adjustment mechanism in the embodiment of this application will first be introduced.

[0062] Reference Figure 2 In the embodiment of the present application, the adjustment mechanism includes a motor 1, a rotating shaft 2, a base plate 3, and an upper cover plate 4, wherein a variable angle exists between the base plate 3 and the upper cover plate 4. The upper cover plate 4 is mounted on the rear of the car model, and the base plate 3 is mounted on the body of the car model. Here, the upper cover plate 4 can serve as a rear wing or a part of the rear wing structure of the car. The present application does not limit its specific shape. In the embodiment of the present application, the motor 1 in the adjustment mechanism is used to drive the upper cover plate 4 to rotate around the rotating shaft 2, thereby changing the angle between the base plate 3 and the upper cover plate 4.

[0063] It should be noted that, since it is necessary to detect and determine the angle between the bottom plate 3 and the upper cover plate 4 during subsequent testing, in the embodiment of the present application, a relevant angle sensor 5 may be installed at the adjustment mechanism to detect and obtain the angle.

[0064] Please refer to Figure 3 , Figure 3 This is a flow chart of a method for obtaining test data of a car model tail wing provided in an embodiment of the present application, referring to Figure 3 The method for obtaining the test data of the car model tail wing includes but is not limited to:

[0065] Step 110: Fix the adjustment mechanism according to the current included angle between the upper cover plate and the bottom plate;

[0066] During this step, to minimize the impact of upper cover plate deflection on the tail wing during aerodynamic testing, the positional relationship between the upper cover and the base plate must be fixed after each adjustment. In other words, the adjustment mechanism must be fixed according to the current angle between the upper cover and the base plate. Specifically, in some embodiments, the upper cover plate can be fixed in position by means of a device such as an electromagnet. Alternatively, in other embodiments, a fixed fixture or other assembly can be used to secure the upper cover and base plate, although this application does not limit this.

[0067] Step 120: Perform an aerodynamic test on the automobile model to obtain a lift coefficient and a drag coefficient obtained from the aerodynamic test;

[0068] In this step, after the upper cover and base are installed, the relevant components can be activated to perform aerodynamic testing on the current car model. Generally speaking, aerodynamic testing requires a wind tunnel laboratory, where the relevant test data is calculated by blowing the test object (i.e., the car model in this application) through the wind tunnel. Specifically, in the embodiments of this application, the relevant equipment and parameters used during the aerodynamic testing process can be implemented in accordance with relevant standards, and this application does not impose any restrictions on this.

[0069] In this step, the lift coefficient and drag coefficient can be obtained during the test process. Here, the lift coefficient is generally the ratio of the lift force on an object to the product of the airflow pressure and the reference area; the drag coefficient is the ratio of the drag force on an object to the product of the airflow pressure and the reference area. They are one of the main indicators for evaluating the aerodynamic performance of a car, which will directly affect the operational stability and power of the car. As the speed of the car increases, the requirements for the lift coefficient and drag coefficient of different models may also be different. Therefore, in the embodiment of the present application, it is necessary to obtain the lift coefficient and drag coefficient obtained by the aerodynamic test of the car model, so as to judge whether it meets the design requirements and determine the appropriate vehicle model structure.

[0070] Step 130: Determine whether the lift coefficient and the drag coefficient are within a predetermined range based on design standard values.

[0071] In this step, after obtaining the lift and drag coefficients from the aerodynamic test, the aerodynamic test data for the vehicle model in the current upper cover state can be determined based on pre-determined design standard values to determine whether it meets the design requirements. Specifically, the lift and drag coefficients can be compared with the design standard values to determine whether they are within a predetermined range.

[0072] Specifically, for example, based on the design standard values, the lift coefficient should be within a range of values for the lift index, which is recorded as the first design range. Furthermore, for the drag index, the drag coefficient should be within a range of values, which is recorded as the second design range. Then, based on whether the lift coefficient obtained from aerodynamic testing is within the first design range, it can be determined whether the lift coefficient is within the predetermined range. Similarly, based on whether the drag coefficient obtained from aerodynamic testing is within the second design range, it can be determined whether the drag coefficient is within the predetermined range.

[0073] It should be noted that in the embodiments of the present application, the specific size and range of the design standard value can be flexibly set as needed, and the present application does not impose any specific restrictions on this.

[0074] Step 140: If at least one of the lift coefficient or the drag coefficient is not within the predetermined range, output the current angle and the stress diagram of the vehicle model;

[0075] In this step, if at least one of the lift coefficient or the drag coefficient is determined to be outside the predetermined range, the current rear wing structure of the car model does not meet the design requirements and requires further adjustment. At this point, the current angle between the base plate and the upper cover can be output, along with a stress diagram of the car model. In this embodiment of the present application, the simultaneous output of stress data from the car model facilitates adjustments to the car's structure based on stress conditions, improving the shape of the rear wing and ultimately enhancing vehicle quality and production design efficiency.

[0076] Step 150 : Control the motor to drive the upper cover to rotate in a predetermined direction by a specified angle, and then return to the step of fixing the adjustment mechanism according to the current angle between the upper cover and the bottom plate.

[0077] In this step, if at least one of the current lift coefficient or drag coefficient is not within the predetermined range, the motor can be controlled to move and control the upper cover to adjust a specified angle in a predetermined direction. Here, the predetermined direction can be either an increasing direction or a decreasing direction, and this application does not impose any restrictions on this. Of course, in order to improve the efficiency of production design, it can be rotated slowly from the smallest angle to the increasing direction. Moreover, in an embodiment of the present application, the angle at which the upper cover is controlled to be "opened" or "closed" each time can be pre-set, for example, it can be 1 degree. In this way, by detecting the angle change during the rotation process, the start and shut down of the motor can be conveniently controlled. After adjusting the position of the upper cover, you can return to the aforementioned step 110 to continue the test, so that you can continue to judge whether the adjusted car model meets the design standards.

[0078] In some embodiments, the method further comprises:

[0079] If the lift coefficient and the drag coefficient are both within the predetermined range, outputting the current angle, the lift coefficient, the drag coefficient, and a stress diagram of the vehicle model;

[0080] Turn off the power supply of the regulating mechanism to end the aerodynamic test.

[0081] In this embodiment of the present application, if both the lift coefficient and the drag coefficient are within the predetermined range, the current vehicle model structure meets the design requirements. The angle between the current floor and upper cover, the lift coefficient, the drag coefficient, and a stress diagram of the vehicle model can then be output. The power to the relevant components of the adjustment mechanism can then be turned off, completing and ending the aerodynamic test.

[0082] In some embodiments, turning off the power supply of the regulating mechanism and ending the aerodynamic test includes:

[0083] Query user instructions;

[0084] When it is determined that the user instruction does not include the need to perform aerodynamic tests at other angles, the power supply of the adjustment mechanism is turned off to end the aerodynamic test.

[0085] In some cases, designers may need to obtain multiple sets of aerodynamic test data for comparison in order to determine the appropriate vehicle structure. Even if the design requirements are met, further testing may still be necessary to facilitate subsequent comparisons. In this case, the user can issue relevant user instructions in advance. By querying the user instructions, it can be determined whether they include requirements for aerodynamic testing at other angles. If not, the power to the adjustment mechanism can be turned off, terminating the aerodynamic test. Otherwise, the test can continue.

[0086] In some embodiments, after controlling the motor to drive the upper cover to rotate in a predetermined direction by a specified angle, returning to the step of fixing the adjustment mechanism according to the current angle between the upper cover and the bottom plate includes:

[0087] Controlling the motor to drive the upper cover to rotate in a predetermined direction by a specified angle, and detecting a first angle after the rotation;

[0088] Comparing the first angle with a preset angle threshold;

[0089] When the first angle is less than or equal to the preset angle threshold, the process returns to the step of fixing the adjustment mechanism according to the current angle between the upper cover plate and the bottom plate.

[0090] When the first angle is greater than the preset angle threshold, the aerodynamic test is ended.

[0091] In an embodiment of the present application, when adjusting the angle by adjusting the structure, if the angle is selected from small to large for testing, it should be noted that due to structural limitations, the inclination of the upper cover plate cannot exceed a certain threshold. For this case, an angle threshold can be set in advance, such as 10 degrees. Each time the upper cover plate is driven to rotate a specified angle in a predetermined direction, the angle after rotation is detected and recorded as the first angle. Then, the first angle is compared with the preset angle threshold. If the first angle is less than or equal to the preset angle threshold, return to the step of fixing the adjustment mechanism according to the current angle between the upper cover plate and the bottom plate, and the test can continue; if the first angle is greater than the preset angle threshold, the aerodynamic test is ended.

[0092] It can be understood that the method for obtaining automobile model tail wing test data provided in the embodiment of the present application can use the upper cover plate to act as the tail wing, and its angle is adjustable. Only one upper cover plate model needs to be made to obtain the aerodynamic data at different tail wing angles, which can greatly improve the convenience of obtaining aerodynamic data and reduce the design cost of the automobile; and during the test process, timely feedback on the stress conditions at various tail wing angles can facilitate designers to adjust the automobile shape according to the automobile model stress data, which is conducive to improving the design and production efficiency of the automobile.

[0099] The driving module is used to control the movement of the motor, drive the upper cover to rotate in a predetermined direction by a specified angle, and then return to the fixing module to execute the step of fixing the adjustment mechanism according to the current angle between the upper cover and the bottom plate.
