[0002] As consumers increasingly demand both environmental friendliness and extended range in automobiles, plug-in hybrid electric vehicles (PHEVs), with their core technological advantages of "pure electric drive + long range," have become the mainstream category in the new energy vehicle market, with cumulative purchases and monthly sales continuing to climb. However, traditional fuel tanks have significant technical shortcomings: they lack targeted pressure regulation structures, ordinary baffle designs have limited effectiveness in suppressing fuel sloshing, and suffer from insufficient compatibility with fuel management systems, easy interference with other vehicle systems such as batteries and ECUs, and weak adaptability to hybrid technologies. This results in rigid fuel sloshing suppression methods and passive control of fuel tank pressure, which not only further exacerbates the compatibility issues with fuel management systems and hybrid technologies but also fails to meet the demands of intelligent vehicle development. Consequently, it increases safety risks such as tank structure fatigue and fuel leakage, seriously affecting fuel supply stability and overall vehicle driving safety. Utility Model Content

Detailed Implementation

[0023] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0024] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0025] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0026] Example 1 Reference Figures 1-5 This is the first embodiment of the present invention. This embodiment provides a vertical baffle fuel tank, which includes a fuel tank 11 and a support component 2. The two work together to prevent internal fuel sloshing and balance internal pressure.

[0027] Including fuel tank 11.

[0028] The fuel tank is a key component in automobiles, especially gasoline-powered vehicles and plug-in hybrid electric vehicles, which are equipped with fuel power systems. It is used to store and protect fuel and to supply fuel stably to the engine. This is existing technology, and this solution will not be described in detail. Moreover, those skilled in the art can clearly understand its working principle.

[0029] Support component 2 is disposed on the inner wall of fuel tank 11 and includes protective component 21. Protective component 21 includes a rotating shaft 211. A stepper motor 212 is disposed on the top of the rotating shaft 211. The stepper motor 212 is disposed on the top of the fuel tank 11. Four guide plates 213 are disposed on the surface of the rotating shaft 211.

[0030] A bearing is provided on the outside of the rotating shaft 211, and a bearing base is fitted on the outside of the bearing. The inner ring of the bearing is interference-fitted with the axial surface of the rotating shaft 211, and the outer ring is transition-fitted with the bearing base housing. The bearing base housing is fixed to the inner wall of the fuel tank 11 by bolts.

[0031] Rotary springs are mounted at both ends of the shaft 211 to provide stable torsional restoring force. When the vehicle is in dynamic conditions such as acceleration, deceleration, or turning, the fuel in the fuel tank 11 will sway violently due to the inertia of motion. The oil impact force acts directly on the deflector 213, and may also cause pressure fluctuations in the fuel tank, triggering the system protection mechanism: the deflector 213 disperses the oil impact force through its structural characteristics to avoid local pressure concentration; the torque generated by the blade after impact will drive the rotary spring to torsion deformation, and the spring will simultaneously generate a reverse elastic torque to accurately offset the oil impact torque and effectively reduce the stress load on the deflector 213; the shaft 211 plays a key role in stabilizing the relative position of the spring, and together with the bearing, reduces the rotational resistance of the support column, ensuring that the deflector 213 can flexibly adjust its angle with the oil fluctuations, further weakening the swaying effect.

[0032] If the oil sloshes violently, causing the pressure inside the oil tank to rise above 50 kPa, the stepper motor 212 will receive the pressure signal in real time and start, driving the rotating shaft 211 to increase its speed, which in turn drives the guide plate 213 to rotate faster, helping to disperse the oil pressure. Through spring buffering and active adjustment by the motor, the internal pressure is pushed down quickly. During the acceleration of the rotating shaft 211, the guide plate 213 will simultaneously adjust its angle on its surface to ensure that the suppression effect on oil sloshing is continuously optimized. The overall logic is reasonable and adaptable to the pressure and sloshing control requirements under dynamic working conditions.

[0033] Example 2 Reference Figures 1-5 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0034] Specifically, the support assembly 2 also includes an adjustment component 22, which includes a sleeve 221 fitted on the outside of the stepper motor 212, with the other end of the sleeve 221 fixed to the top of the rotating shaft 211.

[0035] The stepper motor 212 is equipped with a motor shaft, and a sleeve 221 is fitted on the outside of the motor shaft. The sleeve 221 is synchronously fitted on the outside of the cylinder 222, and one end of the sleeve is fixedly connected to the rotating shaft 211. During operation, after the stepper motor 212 starts, it drives the motor shaft to rotate. The motor shaft drives the sleeve 221 to rotate synchronously through the sleeve fit. Then, with the fixed connection between the sleeve 221 and the rotating shaft 211, the rotating shaft 211 is driven to rotate synchronously. Finally, the rotating shaft 211 drives the guide plate 213 to rotate faster, thereby achieving auxiliary dispersion of hydraulic pressure and ensuring stable pressure inside the oil tank.

[0036] Specifically, a cylinder 222 is fixed at the bottom of the stepper motor 212, and a movable column 223 is provided on the inner wall of the cylinder 222.

[0037] Both cylinder 222 and stepper motor 212 are located outside the fuel tank 11.

[0038] A cylinder 222 is fixed to one end of the motor shaft on the stepper motor 212. The rotation of the motor shaft will drive the cylinder 222 to rotate synchronously, and the movement of the cylinder 222 will drive the movable column 223 to move.

[0039] Specifically, there are two fixing rings 224 on the surface of the movable column 223, which are fixed at the upper and lower ends of the movable column 223 respectively.

[0040] The movement of the movable column 223 causes the fixed ring 224 to move, and the movement of the fixed ring 224 causes the connecting rod 225 to move.

[0041] Specifically, a connecting rod 225 is fixed to the surface of the retaining ring 224.

[0042] The movement of the fixed ring 224 will cause the connecting rod 225 to move.

[0043] Example 3 Reference Figure 4 and Figure 5 This is the third embodiment of the present invention, which is based on the first two embodiments.

[0044] Specifically, a rack 226 is fixed to one end of the connecting rod 225.

[0045] The movement of link 225 will cause rack 226 to move.

[0046] Specifically, the support component 2 also includes a connector 23, which includes a gear 231 that meshes with one side of the rack 226.

[0047] The movement of the connecting rod 225 will drive the rack 226 to move. The movement of the rack 226 will mesh with the gear 231 to make it rotate. The rotation of the gear 231 will drive the support column 232 to rotate.

[0048] Specifically, a support column 232 is fixed to one end of the gear 231, and the other end of the support column 232 is inserted into the inner wall of the guide plate 213.

[0049] One end of the motor shaft of the stepper motor 212 is fixedly connected to the cylinder 222. When the motor shaft rotates, it synchronously drives the cylinder 222 to rotate as well. After the cylinder 222 is activated, it drives the movable column 223 to move linearly. The movement of the movable column 223 is linked to the synchronous displacement of the fixed ring 224. The fixed ring 224 then pulls the connecting rod 225 to generate a transmission action. The displacement of the connecting rod 225 drives the rack 226 to move along a predetermined trajectory. During the movement of the rack 226, it meshes with the gear 231, driving the gear 231 to rotate. Finally, the gear 231 drives the support column 232 to rotate synchronously, realizing the orderly transmission of power.

[0050] Specifically, the inner wall of the guide plate 213 is provided with guide holes 213-1.

[0051] When the vehicle accelerates, decelerates or turns, the impact force generated by the fuel acts directly on the deflector plate 213. The deflector hole 213-1 can divert and guide part of the oil, breaking the "pressure wall" formed by the oil impact and avoiding the impact force from concentrating in a local area of ​​the deflector plate 213.

[0052] Specifically, a sealing ring 233 is fitted on the outside of the support column 232, and the other end of the sealing ring 233 is fixed to the inner wall of the rotating shaft 211.

[0053] The sealing ring 233 is used to fill the connection gap between the support column 232 and the rotating shaft 211, block the leakage of fuel and fuel vapor, and isolate the core sealing component from the intrusion of external impurities. It is suitable for high pressure and fuel corrosion conditions of the fuel tank 11, and ensures the sealing performance and safety of the system.

[0054] During use, when the vehicle accelerates, decelerates, or turns, the fuel in the fuel tank 11 shakes violently due to inertia, and the impact force of the fuel directly acts on the deflector 213. The deflector 213 disperses the impact force through its own structural characteristics, and the surface guide holes 213-1 simultaneously divert part of the fuel, breaking the "pressure wall" effect and avoiding local pressure concentration. The torque generated by the impact on the deflector 213 drives the rotating spring to twist and deform, and the spring generates a reverse elastic torque, which accurately offsets the impact torque of the fuel and relieves the stress on the deflector 213. The rotating shaft 211 stabilizes the relative position of the rotating spring, and the bearing reduces the rotational resistance of the support column, allowing the deflector 213 to flexibly adjust its angle with the fuel fluctuations, further dissipating the shaking kinetic energy and weakening the impact of fuel fluctuations. If the oil vibrates violently, causing the pressure inside the oil tank to rise to above 50 kPa, the stepper motor 212 receives the pressure signal in real time and starts. It enhances the regulation effect through a dual transmission path. The first transmission path is that the motor shaft of the stepper motor 212 drives the outer sleeve 221 to rotate synchronously, which in turn drives the rotating shaft 211 to speed up. The guide plate 213 rotates with the rotating shaft at an accelerated speed, and works with the guide hole 213-1 to divert the flow and quickly disperse the oil pressure. Second transmission path: The motor shaft synchronously drives the cylinder 222, which is fixed at one end, to rotate. The cylinder 222's action causes the inner wall movable column 223 to move linearly. The fixed rings 224 at the upper and lower ends of the movable column 223 are displaced along with it, pulling the connecting rod 225 to generate a transmission action. The connecting rod 225 drives the rack 226 to move along a predetermined trajectory. The rack 226 meshes with the gear 231, driving the gear 231 to rotate, which in turn drives the support column 232 inserted into the inner wall of the guide plate 213 to rotate synchronously, assisting the guide plate 213 in angle adaptation adjustment and optimizing the wave suppression effect. Pressure drop and reset: Through the reverse buffering of the rotary spring, the diversion and energy dissipation of the guide plate 213, and the dual active adjustment driven by the stepper motor 212, the pressure in the oil tank drops quickly to a safe range; when the working condition returns to stability, the rotary spring releases elastic potential energy, driving the rotating shaft 211 and the guide plate 213 to reset to the initial position, and the stepper motor 212 stops working.
