[0036] In the related art, there is a lack of a test tool for the degree of mud splashing on vehicle components, which leads to no testing of the protection of engine parts in the research and development design stage, resulting in problems after the vehicle is put into the market.

[0037] In a first aspect, the embodiments of the present application provide a test system for the degree of mud splashing on vehicle components, comprising: a mud splashing simulation assembly 1, a rotating test platform 4, and an image detection assembly 5; wherein,

[0038] The mud splashing simulation assembly 1 is used to perform mud splashing tests on the to-be-tested component 3 of the to-be-tested vehicle 2. The rotating test platform 4 is used to accommodate the to-be-tested component 3 and drive the to-be-tested component 3 to rotate to concentrate the mud and water inside the to-be-tested component 3. The image detection assembly 5 is used to capture images of the to-be-tested component 3 of the rotating test platform 4 before and after the mud splashing test to obtain first image data and second image data, respectively, and compare the first image data and the second image data to determine the degree of mud splashing on the to-be-tested component 3.

[0039] It should be noted that the to-be-tested component 3 generally refers to the vehicle intake system. As shown in Figure 3 Since it is generally installed at the bottom of the to-be-tested vehicle 2, the daily driving intake system is easily affected by splashing mud and water, so it is particularly important to test the mud splashing performance of the intake system.

[0040] It is worth noting that the above embodiments set a rotating test platform and an image detection device. The rotating test platform rotates the to-be-tested component before and after the mud splashing test to the same position and posture to facilitate the image detection device to collect images of the to-be-tested component. Further, the rotating test platform drives the to-be-tested component to rotate to monitor whether the splashing mud and water inside the to-be-tested component will be concentrated, so that the operator can obtain accurate test results to accurately determine the degree of mud splashing on the vehicle component.

[0041] In some specific embodiments, as shown in Figure 2 and Figure 3 The rotating test platform 4 comprises a bottom column platform 41, a rotating disc 42, and a driving part; wherein,

[0042] A bottom column platform 41 is internally provided with a cavity; a rotating disc 42 is arranged on the bottom column platform 41; a driving part is installed in the cavity of the bottom column platform 41 and connected with the rotating disc 42, and the driving part is used to drive the rotating disc 42 to rotate to drive the to-be-tested part 3 to rotate.

[0044] Further, as shown in the figure, Figure 3 The rotating disc 42 is provided with a fixing part 421 at the bottom, and one end of the fixing part 421 penetrates through the bottom column platform 41 and is connected with the driving part.

[0049] The image shot by the shooting device 51 is used to display whether there is visible mud in the to-be-tested part 3, and the image shot by the shooting device 51 is input into the processor 52 through the transmission line. The processor 52 can compare the difference between the first image data and the second image data before and after the mud splashing test, and then judge the mud splashing degree of the to-be-tested part 3 after the test, and then judge whether the design of the to-be-tested part 3 is qualified.

[0050] In a preferred embodiment of the present application, as shown in the figure, Figure 1 The mud splashing simulation assembly 1 includes a mud road 11 provided with a groove 111, and the groove 111 is filled with mud.

[0051] It can be understood that the mud splashing onto the vehicle can be simulated by driving the vehicle 2 to pass through the muddy road 11, and the accuracy of the test is improved.

[0052] In combination with the above embodiments, in two preferred embodiments, the mud splashing simulation assembly 1 comprises a plurality of spraying devices installed on the vehicle 2 to be tested, and the spraying devices are used to spray the parts 3 to be tested on the vehicle 2 to be tested.

[0055] Specifically, in an embodiment of the application, the vehicle part mud splashing test system comprises a mud splashing simulation assembly 1, a rotating test platform 4, and an image detection assembly 5.

[0056] The mud splashing simulation assembly 1 is used to test the parts 3 to be tested on the vehicle 2 to be tested; the rotating test platform 4 is used to accommodate the parts 3 to be tested and drive the parts 3 to be tested to rotate to concentrate the mud inside the parts 3 to be tested. The image detection assembly 5 is used to take images of the parts 3 to be tested on the rotating test platform 4 before and after the mud splashing test to obtain first image data and second image data, respectively, and compare the first image data and the second image data to determine the mud splashing degree of the parts 3 to be tested.

[0057] It should be noted that the parts 3 to be tested generally refer to the vehicle intake system. Figure 3 As shown, since it is generally installed at the bottom of the vehicle 2 to be tested, the daily driving intake system is easily affected by the splashing mud, so it is particularly important to test the anti-mud performance of the intake system.

[0058] It is worth noting that the above embodiments set the rotating test platform and the image detection device, and the rotating test platform rotates the parts to be tested before and after the mud splashing test to the same position and posture to facilitate the image detection device to collect images of the parts to be tested. Further, the rotating test platform drives the parts to be tested to rotate to monitor whether the splashing mud inside the parts to be tested will gather, so that the operator can obtain accurate test results to accurately determine the mud splashing degree of the vehicle parts.

[0059] In some specific embodiments, as shown in Figure 2 and Figure 3As shown, the rotating test platform 4 comprises a column platform 41, a rotating disc 42 and a driving part; wherein,

[0061] It is worth mentioning that the rotating disc 42 can drive the to-be-tested part 3 to rotate by rotating, so as to rotate the to-be-tested part 3 to a suitable position, not only can the to-be-tested part 3 keep the same posture when the images are taken before and after the mud splashing test, but also can reduce the error of subsequent image recognition and analysis.

[0062] Further, as shown in the figure, Figure 3 The rotating disc 42 is provided with a fixing part 421 at the bottom, and one end of the fixing part 421 is connected with the driving part through the column platform 41. In some optional embodiments, the driving part comprises a driving motor.

[0063] It can be understood that the electric driving mode of the driving motor is easy to control and adjust by the operator, and the operator can perform remote control.

[0064] In a specific embodiment of the present application, as shown in the figure, Figure 2 The image detection assembly 5 comprises a shooting device 51 and a processor 52; wherein,

[0065] The shooting device 51 is used to shoot the internal image of the to-be-tested part 3 to obtain the first image data and the second image data. The processor 52 is signal-connected with the shooting device 51, and the processor 52 is used to receive the first image data and the second image data and compare and judge the first image data and the second image data.

[0066] Optionally, the shooting device 51 is signal-connected with the processor 52 through a transmission line. The processor 52 can be a computer.

[0067] The image shot by the shooting device 51 is used to display whether there is visible mud in the to-be-tested part 3, and the image shot by the shooting device 51 is input into the processor 52 through the transmission line. The processor 52 can compare the difference between the first image data and the second image data before and after the mud splashing test, so as to judge the mud splashing degree of the to-be-tested part 3 after the test, and further judge whether the design of the to-be-tested part 3 is qualified.

[0068] In combination with the above embodiments, in a preferred embodiment of the present application, as shown in the figure, Figure 1As shown, the mud splashing simulation component 1 includes: a mud and water road 11, on which a groove 111 is provided, and the groove 111 is filled with mud and water.

[0069] Understandably, driving the test vehicle 2 across the muddy road 11 can realistically simulate the situation of mud and water splashing onto the vehicle, thus improving the accuracy of the test.

[0070] In conjunction with the above embodiments, this application provides two preferred embodiments in which the mud splashing simulation component 1 includes: a plurality of spraying devices installed on the vehicle under test 2, the spraying devices being used to spray the components 3 under test on the vehicle under test 2.

[0071] It is worth noting that using a spray device to directly spray the vehicle under test 2 while it is in motion can easily achieve the mud and water test, effectively saving the test cost.

[0072] Thirdly, this application provides a method for testing the degree of mud splashing on vehicle parts using the above-mentioned testing system, comprising:

[0073] Step S1: Place the component to be tested 3 on the rotating test platform 4, and use the image detection component 5 to take the first picture of the component to be tested 3 to obtain the first image data.

[0074] Specifically, step S1 above includes:

[0075] Step S1a: Clean the test components 3 on the vehicle 2 before the test.

[0076] It should be noted that before testing, it is necessary to confirm that the component to be tested (3) is free of impurities to reduce test errors.

[0077] Step S1b: Place the component to be tested 3 on the rotating test platform 4.

[0078] It should be noted that, as Figure 2 As shown, the component to be tested 3 is placed on the rotating test platform 4. The orientation of the component to be tested 3 is adjusted by rotating the test platform 4 so that it is aligned with the image detection component 5, and the orientation and position of the component to be tested 3 at this time are recorded.

[0079] Step S1c: After using the image detection component 5 to take the first picture of the component 3 to be tested to obtain the first image data, the component 3 to be tested is then installed on the vehicle 2 to be tested.

[0080] It is worth noting that after the image detection component 5 captures the first image data, it transmits the first image data to the processor 52.

[0081] Step S2, install the to-be-tested component 3 on the to-be-tested vehicle 2, and use the splashing mud simulation assembly 1 to test the to-be-tested vehicle 2.

[0082] Specifically, when the splashing mud simulation assembly 1 includes the muddy road 11, the to-be-tested vehicle 2 is driven to pass through the muddy road 11 of the splashing mud simulation assembly 1 at a preset vehicle speed.

[0083] Preferably, the to-be-tested vehicle 2 passes through the muddy road 11 at a speed of 40 km / h, and repeats the to-and-fro for 10 times.

[0084] Step S3, after the test is completed, the to-be-tested component 3 on the to-be-tested vehicle 2 is removed and placed on the rotating test platform 4.

[0085] Specifically, the rotating disc 42 is driven to rotate for a preset time length by the driving part, and the to-be-tested component 3 is parked at the same position as the first time when the rotating disc 42 stops rotating. Alternatively, the rotating disc 42 rotates for a preset time length, which can be set to 10 minutes.

[0086] It can be understood that the rotating disc 42 rotates for a preset time length, so as to confirm whether there is muddy water in the to-be-tested component 3, and if there is, it can be gathered together during the rotation.

[0087] Step S4, the to-be-tested component 3 is photographed for the second time by the image detection assembly 5 to obtain second image data, and the degree of splashing mud of the to-be-tested component 3 is determined according to the comparison result of the first image data and the second image data.

[0088] Specifically, the processor 52 is used to compare the photos of the first image data and the second image data, and if there is muddy water with a diameter greater than 5 mm, it is considered that the to-be-tested component 3 is not reasonably designed and needs to be redesigned. Then, the test is performed again until there is no muddy water with a diameter greater than 5 mm before and after the test.

[0089] In a fourth aspect, the application provides a method for optimizing the degree of splashing mud of a vehicle component, which comprises:

[0090] Step S1, place the to-be-tested component 3 on the rotating test platform 4, and photograph the to-be-tested component 3 for the first time by the image detection assembly 5 to obtain first image data.

[0091] Specifically, the above step S1 comprises:

[0092] Step S1a, clean the to-be-tested component 3 on the to-be-tested vehicle 2 before the test.

[0093] It should be noted that the to-be-tested component 3 needs to be confirmed to be free of impurities before the test to reduce the test error.

[0094] Step S1b, placing the to-be-tested component 3 on the rotating test platform 4.

[0095] It should be noted that, as shown in Figure 2 the to-be-tested component 3 is placed on the rotating test platform 4, the posture of the to-be-tested component 3 is adjusted by the rotating test platform 4 to align with the image detection assembly 5, and the posture and position of the to-be-tested component 3 at this time are recorded.

[0096] Step S1c, after the image detection assembly 5 is used to take the first image data of the to-be-tested component 3, the to-be-tested component 3 is installed on the to-be-tested vehicle 2.

[0097] It should be noted that, after the image detection assembly 5 takes the first image data, the first image data is transmitted to the processor 52.

[0098] Step S2, installing the to-be-tested component 3 on the to-be-tested vehicle 2, and using the splashing mud simulation assembly 1 to test the to-be-tested vehicle 2.

[0099] Specifically, when the splashing mud simulation assembly 1 includes the muddy road 11, the to-be-tested vehicle 2 is driven to pass through the muddy road 11 of the splashing mud simulation assembly 1 at a preset vehicle speed.

[0100] Preferably, the to-be-tested vehicle 2 passes through the muddy road 11 at a speed of 40 km / h, and repeatedly goes back and forth 10 times.

[0101] Step S3, after the test is completed, the to-be-tested component 3 on the to-be-tested vehicle 2 is removed and placed on the rotating test platform 4.

[0102] Specifically, the rotating disc 42 is driven to rotate for a preset time length by the driving part, and the to-be-tested component 3 is parked at the same position as the first time when the rotating disc 42 stops rotating. Alternatively, the rotating disc 42 rotates for a preset time length, which can be set to 10 minutes.

[0103] It can be understood that the rotating disc 42 rotates for a preset time length in order to confirm whether there is mud in the to-be-tested component 3, and if there is, it can be gathered together during the rotation.

[0104] Step S4, using the image detection assembly 5 to take the second image data of the to-be-tested component 3, and judging the splashing mud degree of the to-be-tested component 3 according to the comparison result of the first image data and the second image data.

[0105] Specifically, the processor 52 is used to compare the photos of the first image data and the second image data, and if there is mud with a diameter greater than 5 mm, it is considered that the to-be-tested component 3 is not reasonably designed.

[0106] Step S5, the to-be-tested part 3 is redesigned. Then the above steps S1 to S4 are repeatedly executed until the image comparison result before and after the test shows that the to-be-tested part 3 has no mud with a diameter greater than 5mm.

[0107] In summary, the application sets the rotating test platform and the image detection device, and rotates the to-be-tested part before and after the mud test to the same position and posture through the rotating test platform, so as to facilitate the image detection device to collect images of the to-be-tested part. Further, the rotating test platform drives the to-be-tested part to rotate, so that the mud possibly existing in the to-be-tested part is gathered, and then the operator can obtain accurate test results to accurately judge the degree of mud splashing of the vehicle part.
