[0002] A fuel tank is usually installed in a car to store the fuel required for the operation of the car engine. During the operation of the car, the fuel inside the fuel tank shakes due to inertia. During the shaking process, the fuel may hit the inner wall of the fuel tank or squeeze the air in the corner of the fuel tank, or the fuel itself may collide, thereby generating noise.

[0003] At present, in order to reduce the above noise, before designing the fuel tank, the test equipment is usually used to simulate the shaking of the fuel tank during vehicle operation and detect the noise generated during the shaking of the fuel tank, and then the fuel tank is designed based on the noise. In existing test equipment, noise is usually detected by a noise acquisition mechanism. On this basis, some test equipment can also be provided with an image acquisition mechanism to acquire an image of the medium inside the simulated fuel tank, and analyze the noise in combination with the image. However, the quality of the images acquired by the image acquisition mechanism in the existing test equipment needs to be improved, and it is difficult to accurately capture the location where the collision noise is generated by the medium inside the fuel tank based on the images it acquires.

DETAILED DESCRIPTION

[0022] In order to more clearly understand the above-mentioned objectives, features and advantages of the present disclosure, the scheme of the present disclosure will be further described below. It should be noted that the embodiments of the present disclosure and the features in the embodiments can be combined with each other without conflict.

[0023] In the following description, many specific details are set forth to facilitate a full understanding of the present disclosure, but the present disclosure may also be implemented in other ways different from those described herein; it is obvious that the embodiments in the specification are only part of the embodiments of the present disclosure, rather than all of the embodiments.

[0024] Figure 1 It is a schematic diagram of the structure of the test equipment provided in some embodiments of the present application.

[0025] like Figure 1 As shown, in the first aspect, the embodiment of the present application provides a test device, including a carrying mechanism 10, a simulated oil tank 20, an image acquisition mechanism 30 and a light source mechanism 40, wherein the carrying mechanism 10 is movably arranged along a first direction X; the simulated oil tank 20 is arranged on the carrying mechanism 10; the image acquisition mechanism 30 is arranged on the carrying mechanism 10 and is located on one side of the simulated oil tank 20 along the first direction X, and the image acquisition mechanism 30 is used to acquire an image of the medium inside the simulated oil tank 20; the light source mechanism 40 is arranged on the carrying mechanism 10 and is located on one side of the simulated oil tank 20 along the second direction Y, the light source mechanism 40 is movably arranged along the first direction X, and is used to irradiate light to the medium inside the simulated oil tank 20, and the light is configured to be gathered at least along the first direction X, and the first direction X and the second direction Y are intersected.

[0026] The first direction X may be any one of the length direction and the width direction of the simulated oil tank 20, and the second direction Y may be the other. Optionally, the simulated oil tank 20 is configured to reveal its internal medium, that is, the simulated oil tank 20 may be a transparent oil tank or a translucent oil tank, so that the image acquisition mechanism 30 can acquire an image of the internal medium of the simulated oil tank 20, or an opening exposing the internal medium may be provided on the simulated oil tank 20, and the opening corresponds to the image acquisition mechanism 30 and the light source mechanism 40 respectively, so that the image acquisition mechanism 30 can acquire an image of the internal medium of the simulated oil tank 20 from the opening, and the light source mechanism 40 can irradiate light into the internal medium of the simulated oil tank 20. Optionally, the bearing mechanism 10 may be driven by linear drive components such as a linear slide 51, a drive cylinder, and a lead screw guide to move along the first direction X.

[0027] When the supporting mechanism 10 moves along the first direction X, the simulated oil tank 20 moves with the supporting mechanism 10, and the medium inside the simulated oil tank 20 will shake due to inertia during the movement, which may generate noise. In this process, by setting the image acquisition mechanism 30 on one side of the simulated oil tank 20 along the first direction X, and setting the light source mechanism 40 on one side of the simulated oil tank 20 along the second direction Y, the light source mechanism 40 irradiates light along the second direction Y toward the medium inside the simulated oil tank 20, and the light can be gathered in the first direction X. Therefore, the image acquisition mechanism 30 can capture a slice image of the medium inside the simulated oil tank 20 on the plane where the light is located, and thus the medium inside the simulated oil tank 20 can be sliced ​​and analyzed based on the slice image, and it can be determined whether it generates noise at the corresponding position. It can be understood that the noise generated inside the simulated oil tank 20 is usually collision noise, for example, the noise generated when the media inside the simulated oil tank 20 collide with each other, the noise generated when the media inside the simulated oil tank 20 collides with the wall of the simulated oil tank 20, or the noise generated when the media inside the simulated oil tank 20 squeezes the air at the corner of the simulated oil tank 20, etc. Since the medium morphology at the position where noise is generated inside the simulated oil tank 20 is different from the medium morphology at the position where no noise is generated, it can be judged based on the image whether the medium inside the simulated oil tank 20 generates noise at the corresponding position.

[0028] It can be understood that the number of light rays emitted by the light source mechanism 40 is usually multiple, and the planes where the multiple light rays are located are different planes. Therefore, when the multiple light rays are incident on the internal medium of the simulated oil tank 20, the image acquisition mechanism 30 will simultaneously capture the slice images of the internal medium of the simulated oil tank 20 on the multiple planes where the multiple light rays are located. The multiple slice images are usually overlapped along the first direction X, so it is difficult to distinguish the multiple slice images, and it is also difficult to accurately analyze the position where the noise is generated by the internal medium of the simulated oil tank 20. Therefore, in this embodiment, the light rays are set to converge in the first direction X, so that most of the light rays emitted by the light source mechanism 40 are approximately located in the same plane in the first direction X, and the plane is used as the reference plane. When the light rays are incident on the internal medium of the simulated oil tank 20, the brightness of the light rays on the reference plane is the highest. Therefore, the image acquisition mechanism 30 can clearly capture the slice images of the internal medium of the simulated oil tank 20 on the reference plane, so as to accurately analyze the position where the noise is generated by the internal medium of the simulated oil tank 20.

[0029] In the test device provided in the present embodiment, the simulated oil tank 20, the image acquisition mechanism 30 and the light source mechanism 40 are all arranged on the carrying mechanism 10, so that the simulated oil tank 20, the image acquisition mechanism 30 and the light source mechanism 40 can be driven to move along the first direction X through the carrying mechanism 10. In this process, since the image acquisition mechanism 30 is located on one side of the simulated oil tank 20 along the first direction X, and the light source mechanism 40 is located on one side of the simulated oil tank 20 along the second direction Y, the first direction X and the second direction Y are arranged to intersect. Therefore, when the light source mechanism 40 irradiates light to the internal medium of the simulated oil tank 20, and the light is gathered at least along the first direction X, the image acquisition mechanism 30 can more clearly acquire a slice image of the internal medium of the simulated oil tank 20 on the plane where the light is located, so as to improve the image quality. Since the light source mechanism 40 is movably arranged along the first direction X, in different test processes, by adjusting the position of the light source mechanism 40, the image acquisition mechanism 30 can acquire slice images of multiple positions of the internal medium of the simulated oil tank 20 in the first direction X, thereby performing slice analysis on multiple positions of the internal medium of the simulated oil tank 20 in the first direction X, and accurately capturing the position where the internal medium of the simulated oil tank 20 generates noise.

[0030] It should be clear that when the test equipment captures the position where the medium inside the simulated oil tank 20 generates noise, the position can be processed. For example, an oil baffle can be set at the corresponding position to reduce the possibility of the oil tank generating noise at this position.

[0031] It should be clarified that the test equipment provided in the present application can capture other positions of the internal medium of the simulated oil tank 20 by performing slice analysis on the internal medium of the simulated oil tank 202, in addition to capturing the position where the internal medium of the simulated oil tank 20 generates noise, and this embodiment is not limited to this.

[0032] Optionally, the light source mechanism 40 may be movably arranged along the second direction Y, and by moving the position of the light source mechanism 40 along the second direction Y, the distance between the light source mechanism 40 and the simulated oil tank 20 is adjusted, so that the light emitted by the light source mechanism 40 is gathered.

[0033] Optionally, the image acquisition mechanism 30 can be configured as a high-speed camera, so that when the supporting mechanism 10 moves quickly, the image acquisition mechanism 30 can clearly capture the image of the medium inside the simulated oil tank 20. Of course, the image acquisition mechanism 30 can also be other devices capable of acquiring images, which is not limited in this application.

[0034] Optionally, the light source mechanism 40 may be a high-speed laser emitter, which emits laser light to the internal medium of the simulated oil tank 20 so that the image acquisition mechanism 30 can acquire the corresponding slice image. Of course, the light source mechanism 40 may also be other thermal radiation light sources, gas discharge light sources, or electroluminescent light sources, etc., which are not limited in this application.

[0035] Optionally, a fluorescent agent may be provided in the internal medium of the simulated oil tank 20, and the light source mechanism 40 is configured to be able to emit light-speed laser. During the test, a high-speed laser is emitted toward the internal medium of the simulated oil tank 20 along the second direction Y by the light source mechanism 40. The high-speed laser can excite the fluorescent agent in the medium on the plane where the laser is located, causing it to produce fluorescence, thereby facilitating the image acquisition mechanism 30 to acquire a slice image of the internal medium of the simulated oil tank 20 on the plane where the laser is located.

[0036] Optionally, tiny particles of glass beads may also be provided in the internal medium of the simulated oil tank 20, and the light source mechanism 40 is configured to be able to emit light-speed laser. During the test, the light source mechanism 40 emits laser along the second direction Y toward the internal medium of the simulated oil tank 20. The laser irradiates the glass beads on the corresponding plane and can reflect relatively intense light, thereby facilitating the image acquisition mechanism 30 to acquire a slice image of the internal medium of the simulated oil tank 20 on the corresponding plane.

[0037] In some embodiments, the light source mechanism 40 includes a light source body and a focusing lens. The focusing lens is disposed on the light emitting side of the light source body to focus the light emitted by the light source body.

[0038] The focusing lens can focus the light emitted by the light source body, and it can include at least one convex lens, or at least one cylindrical lens, or the focusing lens can also be a combination of focusing lenses such as cylindrical lenses, which is not limited in this embodiment.

[0039] In this embodiment, a focusing lens is provided on the light emitting side of the light source body to converge multiple light rays emitted by the light source body. Compared with moving the position of the light source mechanism 40 along the second direction Y to converge the light rays, this can avoid causing the position of the light source mechanism 40 to be offset in other directions, thereby improving the reliability of the test.

[0040] Figure 2 It is a schematic diagram of the structure of a light source bracket provided in some embodiments of the present application.

[0041] like Figure 1 and Figure 2As shown, in some embodiments, the testing device also includes a light source bracket 50, the light source bracket 50 includes a slide rail 51 extending along a first direction X and a support column 52 extending along a third direction Z, the support column 52 is arranged on the supporting mechanism 10, the slide rail 51 is connected to the support column 52, the light source mechanism 40 is clamped on the slide rail 51, and is slidably arranged relative to the slide rail 51 along the first direction X, and the third direction Z is perpendicular to the first direction X.

[0042] The third direction Z may be the height direction of the simulated oil tank 20. The light source mechanism 40 is indirectly disposed on the bearing mechanism 10 through the light source bracket 50. Specifically, the support column 52 extends along the third direction Z, one end of which is connected to the bearing mechanism 10, and the other end is connected to the slide rail 51 to support the slide rail 51. The light source mechanism 40 is clamped on the slide rail 51 to facilitate the assembly and disassembly of the light source mechanism 40. Among them, a clamping groove may be formed on the light source mechanism 40, and the clamping groove may include a bottom wall and side walls arranged oppositely along the second direction Y, the bottom wall abuts against one side of the slide rail 51 along the first direction X, and the two side walls are clamped on the opposite sides of the slide rail 51 along the second direction Y to achieve the clamping of the light source mechanism 40 and the slide rail 51. In addition, the clamping groove may include at least two openings arranged oppositely along the first direction X, and the slide rail 51 passes through the two openings respectively, so that the light source mechanism 40 can slide relative to the slide rail 51 along the first direction X.

[0043] Optionally, there may be a plurality of support columns 52 , which are spaced apart along the first direction X, so that the slide rail 51 is supported by the plurality of support columns 52 to improve the stability of the slide rail 51 and the light source mechanism 40 mounted on the slide rail 51 .

[0044] In some embodiments, the support column 52 includes a first column and a second column, the first column is connected to the supporting mechanism 10, and the second column is connected to the slide rail 51. The first column is recessed with a slot on the side away from the supporting mechanism 10 along the third direction Z, and the second column is snapped into the slot along the third direction Z, thereby realizing a detachable connection between the first column and the second column, which is convenient for local maintenance and replacement.

[0045] Figure 3 is another structural schematic diagram of a test device provided in some embodiments of the present application, Figure 4 is a top view of a testing device provided in some embodiments of the present application.

[0046] like Figure 3 and Figure 4As shown, in some embodiments, the testing equipment also includes a light blocking mechanism 60 arranged on the supporting mechanism 10, and the light blocking mechanism 60 is located on the side of the simulated oil tank 20 away from the light source mechanism 40 along the second direction Y, and the projection of the simulated oil tank 20 on the light source mechanism 40 along the second direction Y is located within the projection of the light blocking mechanism 60 on the light source mechanism 40 along the second direction Y. Therefore, the light blocking mechanism 60 can block the light emitted by the light source mechanism 40 on the side of the simulated oil tank 20 away from the light source mechanism 40, so as to shorten the path of light propagation, improve the brightness of the light, and thereby improve the clarity of the slice image captured by the image acquisition mechanism 30.

[0047] In some embodiments, the light blocking mechanism 60 includes a light blocking plate and a mounting column, the mounting column extends along the third direction Z, the light blocking plate includes a plate body and a clamping column arranged on the plate body, the clamping column is inserted into the mounting column along the third direction Z, and the third direction Z is perpendicular to the second direction Y.

[0048] The light shield is inserted into the mounting column through the clamping column, and the structure is simple and the assembly and disassembly are convenient. Specifically, the mounting column is arranged on the supporting mechanism 10, and a side thereof away from the supporting mechanism 10 along the third direction Z can be recessed to form a slide groove, and the bottom wall and the opening of the slide groove are arranged oppositely along the third direction Z, so the clamping column can be inserted into the slide groove from the opening of the slide groove.

[0049] Optionally, the number of the mounting posts may be two, the two mounting posts are spaced apart along the first direction X, and the light blocking plate may include two clamping posts, the two clamping posts are respectively inserted into the two mounting posts, thereby improving the structural stability of the light blocking plate.

[0050] In some embodiments, the testing equipment also includes a noise collection mechanism, which is disposed on the supporting mechanism 10 and is disposed close to the simulated oil tank 20. Therefore, while the internal medium of the simulated oil tank 20 is sliced ​​and analyzed by the image acquisition mechanism 30 and the light source mechanism 40, the noise collection mechanism can synchronously collect the noise generated by the internal medium of the simulated oil tank 20 during the movement, without setting up additional tests for detecting the noise, thereby improving the testing efficiency.

[0051] In some embodiments, the noise collection mechanism and the image collection mechanism 30 are integrated into an integral structure, so that the structure of the test device can be more compact and the overall volume of the test device can be reduced.

[0052] In some embodiments, the image acquisition mechanism 30 is movably disposed along the first direction X and / or the second direction Y, so that by adjusting the position of the image acquisition mechanism 30, the acquisition range of the image acquisition mechanism 30 and the clarity of the image acquired can be reasonably adjusted, so as to facilitate overall or partial slicing analysis and testing of the internal medium of the simulated oil tank 20 according to actual needs.

[0053] For example, when it is necessary to perform a local analysis on the medium inside the simulated oil tank 20, the image acquisition mechanism 30 is moved so that the image acquisition mechanism 30 can clearly acquire a local slice image of the corresponding part of the medium inside the simulated oil tank 20, thereby performing a local slice analysis on the corresponding part of the medium inside the simulated oil tank 20 based on the local slice image. When it is necessary to perform an overall analysis on the medium inside the simulated oil tank 20, the image acquisition mechanism 30 is moved so that it can acquire a slice image of the entire medium inside the simulated oil tank 20, thereby performing an overall slice analysis on the medium inside the simulated oil tank 20.

[0054] Please continue to refer to Figure 1 In some optional embodiments, the carrying mechanism 10 includes a carrying vehicle 11 and two tracks 12 arranged at intervals, the tracks 12 extend along the first direction X, the carrying vehicle 11 includes a main body 111 and two wheel groups connected to the main body 111, the simulated oil tank 20, the image acquisition mechanism 30 and the light source mechanism 40 are all arranged on the main body 111, the two wheel groups are arranged one by one on the two tracks 12, and each wheel group includes at least two wheels 112, so that by driving the carrying vehicle 11 to travel on the track 12, the vehicle operation can be simulated to the greatest extent, thereby improving the accuracy of the internal noise test of the simulated oil tank 20.

[0055] Specifically, in each wheel set, a plurality of wheels 112 may be arranged at intervals along the extension direction of the track 12 , and the axle of each vehicle extends in a direction perpendicular to the extension direction of the track 12 , so that the wheels 112 roll on the track 12 .

[0056] Optionally, the carrying mechanism 10 may further include a driver, which is disposed on the carrying vehicle 11 and is used to drive the carrying vehicle 11 to operate.

[0057] Please continue to refer to Figure 1 In some embodiments, the test device also includes a controller 70, which is arranged on the supporting mechanism 10. The controller 70 is respectively connected to the image acquisition mechanism 30, the light source mechanism 40 and the driver of the supporting mechanism 10 for communication, thereby shortening the information interaction path between the controller 70 and the image acquisition mechanism 30, the controller 70 and the light source mechanism 40, and the controller 70 and the driver of the supporting mechanism 10, improving the interaction efficiency, reducing external signal interference, and improving the reliability of signal transmission.

[0058] It is understandable that the controller 70 can also be connected to the noise collection mechanism in communication to control the operation of the noise collection mechanism. In addition, the controller 70 can also serve as a power device to provide energy for the driver, the noise collection mechanism and the image collection mechanism 30.

[0059] Please continue to refer to Figure 1Optionally, the noise test device may further include a control terminal 80, which is in communication with the controller 70. During the test, the control terminal 80 may send control signals to the driver of the carrying mechanism 10, the image acquisition mechanism 30, the noise acquisition mechanism, the light source mechanism 40, etc. through the controller 70, so that the driver drives the carrying mechanism 10 to move along the first direction X, and at the same time, the image acquisition mechanism 30, the noise acquisition mechanism and the light source mechanism 40 start working. The control terminal 80 may be arranged on the carrying vehicle 11, or may be arranged outside the noise test device. The control terminal 80 may be a mobile terminal device or a fixed terminal device. For example, the control terminal 80 may be various terminal devices such as a mobile phone, a computer, a laptop computer, a tablet computer, etc.
