The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

Furthermore, features defined with "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, unless otherwise stated, "a plurality of" means two or more.

[0040] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0041] Unless otherwise specified, the front-back direction in this application refers to the longitudinal direction of the vehicle, i.e., the X direction; the left-right direction refers to the lateral direction of the vehicle, i.e., the Y direction; and the up-down direction refers to the vertical direction of the vehicle, i.e., the Z direction.

[0042] The following is for reference. Figures 1-7 A wave deflector assembly 100 according to an embodiment of the present invention is described. The wave deflector assembly 100 can effectively suppress the generation of noise, achieve active noise reduction, and eliminate the generation of noise at its source.

[0043] like Figures 1-7 As shown, a wave deflector assembly 100 according to an embodiment of the present invention includes: a wave deflector 1 and an adjustment mechanism.

[0044] The liquid storage structure has a hollow cavity inside for storing liquid. The liquid storage structure can be an oil tank 1000, a water tank, a brake fluid reservoir, a urea solution reservoir, or other structures or devices for storing solutions. This invention will be described using an oil tank 1000 as an example of a liquid storage structure.

[0045] The anti-surge plate 1 is installed inside the liquid storage structure and can be arranged laterally to cover the surface of the solution inside the liquid storage structure, that is, to cover the surface of the oil stored in the oil tank 1000. In this way, when the oil in the oil tank 1000 shakes, such as when the vehicle is accelerating, braking or turning sharply, it can effectively reduce the upward surge of the oil and avoid the oil shaking a lot due to inertia, thus preventing noise. In other words, it prevents the oil surface from having excessive fluctuations and reduces the vibration generated when the oil hits the inner wall of the oil tank 1000, thereby reducing noise.

[0046] Furthermore, the adjustment mechanism is used to adjust the height position of the baffle plate 1 within the liquid storage structure.

[0047] Specifically, the adjustment mechanism can actively adjust the height of the baffle plate 1 within the liquid storage structure, allowing the baffle plate 1 to move to the existing height of the oil surface. This ensures that the baffle plate 1 always covers the oil surface, reducing the gap between the baffle plate 1 and the oil surface. As a result, the oil in the tank 1000 is kept in a state similar to being full, preventing the oil from swaying significantly. This effectively suppresses noise generation and achieves active noise reduction.

[0048] It should be noted that since the noise generated by the oil varies at different heights within the oil tank 1000, the baffle 1 needs to be designed to reduce noise at different liquid levels. This invention, by setting an adjustment mechanism to actively adjust the height of the baffle 1 within the liquid storage structure, allows the baffle assembly 100 to adjust its height in real time according to the oil level, ensuring the oil is always in a near-full state. This eliminates the need to optimize the baffle 1's arrangement based on noise differences at different liquid levels, thus preventing noise generation at its source. In other words, the baffle assembly 100 of this invention can optimize noise at all liquid levels, achieving the best noise reduction effect at all oil heights, thereby greatly improving passenger comfort.

[0049] According to the embodiment of the present invention, the anti-surge plate assembly 100 actively adjusts the height position of the anti-surge plate 1 in the liquid storage structure by setting an adjustment mechanism, so that the anti-surge plate 1 can always cover the surface of the oil, thereby keeping the oil in the oil tank 1000 in a state similar to full oil, and the oil cannot shake significantly, thus effectively suppressing the generation of noise, achieving active noise reduction, and eliminating the generation of noise from the root.

[0050] In some embodiments, the adjustment mechanism includes a drive member and a connector 21. The connector 21 is connected to the baffle plate 1, and the output end of the drive member is connected to the connector 21 to drive the connector 21 to move the baffle plate 1 up and down.

[0051] Specifically, such as Figure 1 and Figure 3 As shown, the adjustment mechanism includes a drive component and a connector 21. The drive component is a power source used to actively output power to drive the baffle plate 1 to rise and fall within the liquid storage structure. The connector 21 is connected to the baffle plate 1 so that when the connector 21 moves, it can drive the baffle plate 1 to move together. In actual design, the connector 21 can be fixedly connected to the baffle plate 1 by assembly or injection molding.

[0052] The output end of the drive component is connected to the connector 21, so that the power of the drive component can be transmitted to the connector 21 to drive the connector 21 to move. When the connector 21 moves, it can drive the baffle plate 1 to rise and fall within the liquid storage structure, thereby realizing the adjustment of the height position of the baffle plate 1 within the liquid storage structure.

[0053] Therefore, the drive component drives the connecting component 21 to move, thereby raising and lowering the anti-surge plate 1. This method is simple, reliable, flexible, convenient, and allows for stable and rapid raising and lowering.

[0054] In some embodiments, the driving component is constructed as a drive motor, which is connected to the connector 21 through a transmission structure to drive the connector 21 to move up and down. That is, the input end of the transmission structure is connected to the output end of the drive motor, and the output end of the transmission structure is connected to the connector 21. Thus, the drive motor can transmit power to the transmission structure, and the transmission structure then transmits power to the connector 21 to drive the connector 21 to move up and down within the liquid storage structure. As a result, when the connector 21 moves, it can drive the baffle plate 1 to move up and down within the liquid storage structure. Thus, the transmission structure realizes the power transmission from the drive motor to the connector 21, converting the rotational motion of the drive motor into the linear lifting motion of the connector 21, making the power transmission efficiency higher and the movement of the connector 21 more stable.

[0055] Furthermore, the transmission structure is constructed as a gear and rack structure or a lead screw structure.

[0056] In other words, the drive motor can be connected to the connector 21 through a gear and rack structure or a lead screw structure to realize the power transmission from the drive motor to the connector 21, converting the rotational motion of the drive motor into the linear lifting motion of the connector 21, thereby achieving precise displacement control of the baffle plate 1, which helps to enhance the effect of the baffle plate 1 in suppressing noise generation.

[0057] In some embodiments, the wave deflector 1 is provided with reinforcing ribs 11, which protrude from the surface of the wave deflector 1.

[0058] Specifically, such as Figure 1 and Figure 2 As shown, the wave deflector 1 is equipped with reinforcing ribs 11. Since the wave deflector 1 is horizontally placed within the liquid storage structure and has a large area, using only the connecting piece 21 to move the wave deflector 1 may pose a strength risk, potentially leading to breakage at the connection between the connecting piece 21 and the wave deflector 1. Therefore, reinforcing ribs 11 are provided on the wave deflector 1 to enhance its structural strength and rigidity, making its movement more reliable and stable. For example, Figure 1 and Figure 2 As shown, the reinforcing rib 11 protrudes upward on the surface of the baffle plate 1. Of course, the reinforcing rib 11 can also protrude downward on the surface of the baffle plate 1 to strengthen the baffle plate 1.

[0059] In some embodiments, the reinforcing rib 11 includes a first reinforcing rib 111 and a second reinforcing rib 112, wherein the first reinforcing rib 111 is configured to extend in a direction away from the adjustment mechanism, and the second reinforcing rib 112 is configured to extend in a direction away from the first reinforcing rib 111.

[0060] Specifically, such as Figure 1 and Figure 2As shown, the adjustment mechanism can be located in the middle of the liquid storage structure to facilitate more stable up-and-down movement of the entire baffle plate 1, preventing lateral deviation and swaying during movement. The reinforcing ribs 11 include a first reinforcing rib 111 and a second reinforcing rib 112. The first reinforcing rib 111 extends away from the adjustment mechanism, i.e., towards the periphery of the adjustment mechanism, effectively reinforcing the periphery of the adjustment mechanism and preventing breakage and severe deformation at the connection between the adjustment mechanism and the baffle plate 1, thus affecting the movement of the baffle plate 1. The second reinforcing rib 112 extends away from the first reinforcing rib 111, reinforcing the periphery of the first reinforcing rib 111. Thus, the first and second reinforcing ribs 111 extend in different directions, forming a shape similar to the veins of a leaf, effectively enhancing the overall structural strength and rigidity of the baffle plate 1, ensuring stable and reliable movement.

[0061] In other embodiments, there are multiple reinforcing ribs 11, which are spaced apart and distributed on the wave deflector plate 1.

[0062] In other words, the number of reinforcing ribs 11 can be set to two, three, four or even more. By setting multiple reinforcing ribs 11, the baffle plate 1 can be reinforced at multiple locations, improving the baffle plate 1's ability to resist deformation, thereby enhancing the overall rigidity and stability of the baffle plate 1 and improving the overall structural strength of the baffle plate 1. This prevents the baffle plate 1 from breaking, severely deforming and being damaged due to excessive local stress, thus extending the service life of the baffle plate 1.

[0063] Multiple reinforcing ribs 11 are spaced apart on the wave deflector plate 1, that is, multiple reinforcing ribs 11 are spaced apart on the wave deflector plate 1 to strengthen the overall structure of the wave deflector plate 1. Under the premise of ensuring the strength and rigidity of the wave deflector plate 1, the overall thickness of the wave deflector plate 1 can be reduced by reasonably arranging multiple reinforcing ribs 11, thereby saving the amount of material used in the wave deflector plate 1 and reducing the weight of the wave deflector plate 1, thus reducing the manufacturing cost.

[0064] The present invention also proposes an oil tank 1000.

[0065] The fuel tank 1000 according to an embodiment of the present invention includes a fuel tank housing 3 and a baffle assembly 100 of any of the above embodiments, wherein the fuel tank housing 3 is configured as a liquid storage structure.

[0066] Specifically, such as Figure 1 As shown, the fuel tank 1000 includes a fuel tank shell 3 and a baffle assembly 100. The fuel tank shell 3 is constructed as a liquid storage structure, that is, the interior of the fuel tank shell 3 is hollow to form a liquid storage cavity, which stores fuel for combustion. The baffle 1 is installed inside the fuel tank shell 3.

[0067] By setting an adjustment mechanism to actively adjust the height of the baffle plate 1 within the liquid storage structure, the baffle plate 1 can always cover the surface of the oil, thus keeping the oil in the oil tank 1000 in a state similar to full oil, preventing the oil from shaking significantly. This effectively suppresses noise generation, achieves active noise reduction, and eliminates noise generation at its source.

[0068] In some embodiments, the fuel tank housing 3 is provided with a first fuel tank column 31, the baffle plate 1 is provided with a first clearance hole 12, the first fuel tank column 31 passes through the first clearance hole 12, and the first clearance hole 12 is configured to move up and down along the first fuel tank column 31.

[0069] Specifically, such as Figure 1 As shown, a first fuel tank column 31 is provided inside the fuel tank shell 3. The first fuel tank column 31 is cylindrical and extends vertically upward. It can also be constructed as a polygonal column or other structural shapes. The first fuel tank column 31 is mainly used to provide internal structural support, improve the overall structural strength, rigidity and compressive strength of the fuel tank shell 3, and effectively disperse the vibration and impact from all directions during vehicle operation. This prevents the fuel tank 1000 from deforming or even breaking when the vehicle is in motion or subjected to external impact, reduces the risk of oil leakage, ensures the safety of oil storage, and thus improves the safety of the vehicle.

[0070] The baffle plate 1 is provided with a first clearance hole 12, which is used to avoid the first fuel tank column 31 and prevent the baffle plate 1 from interfering with the first fuel tank column 31. The first clearance hole 12 is provided through the thickness direction of the baffle plate 1, and the shape and size of the first clearance hole 12 match the first fuel tank column 31, so that the first fuel tank column 31 can pass through the first clearance hole 12 and extend upward smoothly to ensure the height of the first fuel tank column 31 so that it can stably support the fuel tank shell 3.

[0071] The first clearance hole 12 is configured to move up and down along the first oil tank column 31. That is, when the baffle plate 1 moves up and down inside the oil tank shell 3, the first clearance hole 12 will also move up and down with the baffle plate 1. The first clearance hole 12 moves up and down along the axial direction of the first oil tank column 31 to avoid interference between the baffle plate 1 and the first oil tank column 31 when the baffle plate 1 moves.

[0072] In practical design, such as Figure 2 As shown, a second clearance hole 13 can also be provided on the baffle plate 1. The second clearance hole 13 is used to avoid the oil pump. The design of the baffle plate 1 should cover the horizontal cross-section of the oil tank shell 3 as much as possible, and the outer periphery of the baffle plate 1 should be reserved with the oil tank shell 3 to facilitate the smooth up and down movement of the baffle plate 1.

[0073] In some embodiments, there are multiple first tank columns 31, and at least one of them is configured as a drive column 32, with an adjustment mechanism mounted on the drive column 32.

[0074] In other words, the number of first fuel tank pillars 31 can be set to two, three, four or even more. Setting multiple first fuel tank pillars 31 to support the fuel tank shell 3 at multiple locations can further improve the structural strength and rigidity of the fuel tank shell 3, thereby further preventing the fuel tank 1000 from deforming or even breaking when the vehicle is in motion or subjected to external impact, reducing the risk of oil leakage, ensuring the safety of oil storage, and thus further improving the safety of the vehicle.

[0075] At least one of the components is a drive column 32, on which the adjustment mechanism is mounted. This means that one, two, or more first oil tank columns 31 can be configured as a drive column 32, depending on actual needs and not limited to the embodiment described herein. The drive column 32 is hollow to form a mounting cavity, within which the adjustment mechanism can be installed. This reduces the space occupied by the adjustment mechanism within the oil tank housing 3, improving the overall integration and compactness of the oil tank 1000, and allowing for the storage of more oil within the oil tank housing 3.

[0076] Specifically, such as Figure 1 As shown, Figure 1 Taking the setting of three first oil tank columns 31 as an example, one of the first oil tank columns 31 is constructed as a drive column 32. The drive component of the adjustment mechanism is installed inside the drive column 32 to reduce the space occupied by the drive component. The connector 21 is installed outside the drive column 32 to facilitate connection with the anti-wave plate 1.

[0077] When multiple drive columns 32 are set, that is, when multiple adjustment mechanisms are set, the movement stability and reliability of the anti-wave plate 1 can be further improved, and when one of the adjustment mechanisms is damaged and cannot work, the other adjustment mechanisms can still work normally.

[0078] The present invention also proposes a control system for the wave deflector assembly 100.

[0079] The control system of the baffle assembly 100 according to an embodiment of the present invention includes a detection module, a control module, and the baffle assembly 100 or the oil tank 1000 of any of the above embodiments. The detection module is used to detect the current liquid level in the liquid storage structure, and the control module is used to control the adjustment mechanism to adjust the baffle 1 to the target height according to the current liquid level.

[0080] Specifically, when the liquid storage structure is constructed as an oil tank shell 31, the solution inside the liquid storage structure is oil. The detection module can detect the current oil level in the liquid storage structure. The current oil level detected by the detection module can be converted into an electrical signal and transmitted to the control module. After receiving the electrical signal, the control module will compare it with the current height of the baffle plate 1. If the difference between the current oil level and the current height of the baffle plate 1 is large, that is, the distance between the surface of the oil and the surface of the baffle plate 1 is large and exceeds the set value, the control module will control the adjustment mechanism to start to adjust the height of the baffle plate 1 to the target height, that is, to the current oil level, so that the oil level is the same as the height of the baffle plate 1, thus suppressing large-scale sloshing of the oil.

[0081] In practical design, the top of the drive motor can be electrically connected to the control module to receive the current signal transmitted by the control module, so as to realize the control module to control the drive motor, and the drive motor can be constructed as a DC motor.

[0082] In some embodiments, an oil float 4 is also included, which floats within the liquid storage structure, and the detection module is configured as a liquid level sensor and is located within the oil float 4.

[0083] Specifically, such as Figure 1 As shown, the control system of the wave deflector assembly 100 also includes an oil float 4. The oil float 4 is a key device in the oil tank 1000 used to measure the oil level. The oil float 4 floats within the liquid storage structure, that is, it floats on the surface of the oil within the liquid storage structure. It moves up and down with the change in the oil surface height due to buoyancy, so the position of the oil float 4 directly reflects the oil level height. The detection module is constructed as a level sensor and is installed inside the oil float 4, so that the level sensor can sense the height position of the oil float 4 in real time to reflect the current oil level height.

[0084] In the actual design, the liquid level sensor transmits a resistance value R to the control module. This is because when designing the oil tank 1000 and the oil pump, there is a calibration (VHR) of oil tank volume - oil level - oil pump resistance. Each resistance value R corresponds to a liquid level height. Therefore, when the control module receives the resistance value R transmitted by the liquid level sensor, it will process it accordingly to obtain the current liquid level height and compare the obtained current liquid level height with the current height of the baffle plate 1.

[0085] In particular, by suppressing the sloshing of the oil, the range of vertical fluctuation of the oil float 4 during vehicle operation is also reduced, thereby optimizing the software filtering and the instrument's range calculation, making the range more accurate.

[0086] The present invention also proposes a control method for a wave deflector assembly 100.

[0087] According to an embodiment of the present invention, a control method for a wave-shielding assembly 100 is applicable to the control system of the wave-shielding assembly 100 in any of the above embodiments, and the control method includes:

[0088] S1: Obtain the current liquid level within the storage structure.

[0089] In other words, the level sensor senses the height position of the oil float 4 in real time and transmits the sensed height position of the oil float 4 to the control module in real time. After receiving the data, the control module processes it accordingly to obtain the current oil level height, that is, the current oil height position.

[0090] S2: Obtain the height position of the wave deflector 1.

[0091] In other words, the control module can obtain the current height position of the wave deflector 1 in real time. In practice, the current height position of the wave deflector 1 can be sensed in real time by a sensor, and the sensor can transmit the real-time sensed current height position of the wave deflector 1 to the control module in real time.

[0092] S3: Selectively adjust the height of the baffle plate 1 according to the current liquid level height and the height of the baffle plate 1.

[0093] In other words, after the control module obtains the current height position of the oil and the current height position of the baffle plate 1, it selectively adjusts the height position of the baffle plate 1 so that the adjusted height position of the baffle plate 1 is the same as or close to the current liquid level.

[0094] In some embodiments, selectively adjusting the height position of the baffle plate 1 based on the current liquid level height position and the height position of the baffle plate 1 includes:

[0095] S31: Obtain the height difference between the current liquid level and the height of the baffle plate 1.

[0096] In other words, after the control module obtains the current height position of the oil and the current height position of the baffle plate 1, it processes the current height position of the oil and the current height position of the baffle plate 1 to obtain the height difference between the current height position of the oil and the current height position of the baffle plate 1.

[0097] S32: When the height difference is greater than or equal to the first set height, control the baffle plate 1 to adjust its height.

[0098] In other words, after the control module obtains the height difference between the current oil level and the current height of the baffle plate 1, it judges the height difference. When the control module determines that the height difference is greater than or equal to the first set height, the control module controls the adjustment mechanism to move to adjust the height of the baffle plate 1. For example, the first set height can be about 15mm, that is, the height position at which the oil will not sway significantly. The first set height can be flexibly set according to the actual situation and needs, and is not limited to the embodiment described herein.

[0099] In some embodiments, when the height difference is greater than or equal to a first preset height, controlling the wave deflector 1 to adjust its height includes:

[0100] S321: Determine the relative position of the baffle plate 1 and the liquid surface of the liquid storage structure.

[0101] In other words, when the control module determines that the height difference is greater than or equal to the first set height, it continues to determine the relative position of the baffle plate 1 and the liquid surface of the liquid storage structure, that is, whether the surface of the oil is above or below the baffle plate 1.

[0102] S322a: When the liquid level of the liquid storage structure is above the baffle plate 1, control the baffle plate 1 to move upward.

[0103] In other words, when the control module determines that the surface of the oil is above the baffle plate 1, the control module controls the adjustment mechanism to start, and the adjustment structure begins to move so that the baffle plate 1 moves upward. The distance that the baffle plate 1 moves upward is the height difference between the current height position of the oil and the current height position of the baffle plate 1.

[0104] S322b: And, when the liquid level of the liquid storage structure is below the baffle plate 1, control the baffle plate 1 to move downward.

[0105] In other words, when the control module determines that the surface of the oil is below the baffle plate 1, the control module controls the adjustment mechanism to start, and the adjustment structure begins to move so that the baffle plate 1 moves downward. The distance that the baffle plate 1 moves downward is the height difference between the current height of the oil and the current height of the baffle plate 1.

[0106] After the baffle plate 1 moves to a new height position, it will output the new height position to the control module, which can continue to compare it with the current oil height position for the next round of adjustment. This cycle repeats to achieve real-time adjustment of the height position of the baffle plate 1.

[0107] The present invention also proposes a vehicle.

[0108] The vehicle according to embodiments of the present invention includes the fuel tank 1000 of any of the above embodiments or the control system of any of the above embodiments.

[0109] By setting an adjustment mechanism to actively adjust the height of the anti-surge plate 1 within the liquid storage structure, the anti-surge plate 1 can always cover the surface of the oil, thus keeping the oil in the oil tank 1000 in a state similar to full oil, preventing the oil from sloshing around significantly. This effectively suppresses noise generation, achieving active noise reduction and eliminating noise at its source. At the same time, it reduces the vertical fluctuation range of the oil float 4 during vehicle operation, thereby optimizing software filtering and improving the instrument's range calculation, making the range calculation more accurate.

[0110] It should be noted that, in this embodiment, the matching of the shaking noise of the fuel tank 1000 may only require one round of preliminary testing, while existing fuel tank 1000 matching of shaking noise requires multiple rounds of testing. Therefore, the fuel tank 1000 in this embodiment can reduce the matching cycle, saving time and cost. Figure 4 The figure shows the resistance output curve when the oil is sloshing normally, i.e., without the oil tank 1000 or control system of this invention. It can be seen that excessive oil sloshing will generate significant noise. Figure 5 The figure shows the resistance output curve when the oil is suppressed, i.e., when the oil tank 1000 or control system of the present invention is installed. It can be seen that the oil sloshing amplitude is very small, thereby greatly reducing the generation of noise.
