Description
Technical Field
[0001] This application relates to a wave deflector, and more particularly to a wave deflector for a fuel tank. Background Technology
[0002] With social development and the improvement of people's living standards, cars have become a common means of transportation. Gasoline is an indispensable resource for cars to run. As the core component for storing fuel, the working environment of the car's fuel tank directly affects the vehicle's driving stability and driving comfort.
[0003] During vehicle operation, the fuel in the tank vibrates violently due to acceleration, deceleration, turning, or bumps, creating irregular fuel waves. These waves repeatedly impact the inner wall of the fuel tank, generating not only continuous low-frequency noise but also potentially causing resonance within the tank itself, further amplifying the noise. Related research indicates that this type of noise is highly efficient at transmitting within the vehicle, especially at low speeds or while idling, significantly interfering with the driver's auditory environment. Prolonged driving in this environment may lead to driver fatigue and even impair driving concentration, posing a potential safety hazard. Utility Model Content
[0004] The purpose of this application is to provide a fuel tank anti-surge plate, which has the advantage of reducing the noise generated by the sloshing of fuel inside the fuel tank during vehicle operation. It solves the problem that the fuel waves formed inside the fuel tank during vehicle operation will generate noise, interfere with the driver's auditory environment, affect the driver's attention, and pose potential safety hazards.
[0005] The present application provides a baffle plate for a fuel tank, which adopts the following technical solution: it includes a fuel tank body and a baffle plate body. The baffle plate body is located inside the fuel tank body. A first dispersion hole is opened inside the baffle plate body. A first baffle is fixedly connected to one side of the baffle plate body. The first baffle is located outside the first dispersion hole. A plurality of second dispersion holes are opened inside the baffle plate body. The plurality of second dispersion holes are evenly arrayed inside the baffle plate body. A second baffle is fixedly connected to one side of the baffle plate body. The second baffle is located at the edge of one side of the baffle plate body. A plurality of mounting plates are fixedly connected to one side of the baffle plate body. A plurality of fixing frames are fixedly connected to the inner wall of the fuel tank body. A mounting plate is provided at the bottom of the fixing frame. A hydraulic damper is fixedly connected to the side of the mounting plate away from the fixing frame. A lifting frame is fixedly connected to the output end of the hydraulic damper. By adopting the above technical solution, during use, the device can cause the fuel sloshing inside the fuel tank to form waves that come into contact with the baffle plate. After contact with the baffle plate, the fuel waves will pass through several second dispersion holes and the first dispersion hole, thereby dispersing the fuel waves and reducing the energy of the fuel impacting the inner wall of the fuel tank, thus reducing noise generation. The hydraulic damper can cause the baffle plate to sway up and down after being impacted by the fuel waves, and reduce the swaying amplitude and impact force of the baffle plate during swaying, thereby further reducing the impact force of the fuel waves on the baffle plate and the inner wall of the fuel tank. This solves the problem that the fuel waves formed inside the fuel tank during vehicle operation will generate noise, interfere with the driver's auditory environment, affect the driver's attention, and pose potential safety hazards. The first baffle 6 and the second baffle 7 protect the edge of the first dispersion hole 6 and the edge of the baffle plate 2, reducing the impact force of the fuel waves on the baffle plate 2 and increasing the life of the baffle plate 2.
[0006] Preferably, the top of the fuel tank body is provided with a top cover, the top cover has a through hole and is fixedly connected to an oil inlet pipe, and the fuel tank body is fixedly connected to the top cover by welding; By adopting the above technical solution, the separation of the top cover from the fuel tank body facilitates the installation of the anti-surge plate body inside the fuel tank body.
[0007] Preferably, the number of the fixing brackets is equal to the number of the mounting plates, and the fixing brackets are fixedly connected to the fuel tank body by welding; By adopting the above technical solution, the fixing bracket is welded inside the fuel tank body, which can enhance the connection between the fixing bracket and the fuel tank body. The connection between the fixing bracket and the mounting plate can enable the fuel tank body to fix the baffle plate body at multiple points, thus enhancing the connection between the fuel tank body and the baffle plate body.
[0008] Preferably, the fixing frame has a threaded hole inside and a positioning bolt is threadedly connected thereto, and the mounting plate has a threaded hole inside that is compatible with the positioning bolt. By adopting the above technical solution, the positioning bolt can be threadedly connected to the mounting plate.

[0009] Preferably, a corrugated telescopic tube is sleeved on the outside of the hydraulic damper, one end of the corrugated telescopic tube is fixedly connected to the mounting plate, and the other end of the corrugated telescopic tube is fixedly connected to the lifting frame. By adopting the above technical solution, the corrugated expansion tube is made of metal. The corrugated expansion tube is sleeved on the outside of the hydraulic damper to protect the hydraulic damper and prevent fuel inside the oil tank from seeping into the hydraulic damper and affecting its use. The expandable and contractile characteristics of the corrugated expansion tube will not affect the use of the hydraulic damper.
[0010] Preferably, the lifting frame has a threaded hole inside and a threaded rod is threadedly connected to it, and the mounting plate has a mounting hole inside that matches the threaded rod. By adopting the above technical solution, the threaded rod can connect the lifting frame and the mounting plate, so that the mounting plate can move up and down together with the lifting frame.

By adopting the above technical solutions, the baffle plate made of cold-rolled steel sheet has high strength, can withstand the impact of fuel sloshing, and has low cost. The galvanized film can improve the rust resistance of the cold-rolled steel sheet.
[0013] In summary, this application includes at least one of the following beneficial technical effects: 1. This type of fuel tank anti-surge plate, through the arrangement of the anti-surge plate body, first dispersion holes, first baffle, second baffle, second dispersion holes, hydraulic damper, and lifting frame, enables the device to, during use, allow the fuel sloshing inside the fuel tank to form waves that come into contact with the anti-surge plate body. After contact with the anti-surge plate body, the fuel waves will pass through several second dispersion holes and first dispersion holes, thereby dispersing the fuel waves and reducing the energy of the fuel impacting the inner wall of the fuel tank body, thus reducing noise generation. The hydraulic damper enables the anti-surge plate body to sway up and down after being impacted by the fuel waves, and reduces the swaying amplitude and impact force of the anti-surge plate during swaying, thereby further reducing the impact force of the fuel waves on the anti-surge plate body and the inner wall of the fuel tank body. This solves the problem that the fuel waves formed inside the fuel tank during vehicle operation generate noise, interfere with the driver's auditory environment, affect the driver's attention, and pose potential safety hazards.

[0016] The following is in conjunction with the appendix Figure 1 - Appendix Figure 5 This application will be described in further detail below.
[0017] Example 1: A baffle plate for a fuel tank, referring to... Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5The system includes a fuel tank body 1 and a baffle body 2. The baffle body 2 is located inside the fuel tank body 1. A first dispersion hole 5 is formed inside the baffle body 2. A first baffle 6 is fixedly connected to one side of the baffle body 2, located outside the first dispersion hole 5. Several second dispersion holes 8 are formed inside the baffle body 2, evenly arranged in an array. A second baffle 7 is fixedly connected to one side of the baffle body 2, located at the edge of one side of the baffle body 2. Several mounting plates 9 are fixedly connected to one side of the baffle body 2. Several fixing brackets 10 are fixedly connected to the inner wall of the fuel tank body 1, and mounting brackets 10 have mounting... The mounting plate 11 has a hydraulic damper 13 fixedly connected to the side of the mounting plate 11 away from the fixing frame 10. The output end of the hydraulic damper 13 is fixedly connected to the lifting frame 15. A top cover 3 is provided above the oil tank body 1. The top cover 3 has a through hole and is fixedly connected to an oil inlet pipe 4. The top cover 3 is fixedly connected to the oil tank body 1 by welding. The number of fixing frames 10 is equal to the number of mounting plates 9. The fixing frames 10 are fixedly connected to the oil tank body 1 by welding. The fixing frames 10 have threaded holes and are threadedly connected to positioning bolts 12. The mounting plate 11 has threaded holes that match the positioning bolts 12. A corrugated expansion tube 14 is sleeved on the outside of the hydraulic damper 13. One end of the corrugated expansion tube 14 is fixedly connected to the mounting plate 11. The other end of the telescopic tube 14 is fixedly connected to the lifting frame 15. The lifting frame 15 has a threaded hole inside and a threaded rod 16 is threadedly connected to it. The mounting plate 9 has a mounting hole 17 inside that matches the threaded rod 16. The threaded rod 16 is threadedly connected to the mounting hole 17. The outer sides of both ends of the threaded rod 16 are respectively threaded with a first positioning nut 18 and a second positioning nut 19. The material of the baffle plate body 2 is cold-rolled steel plate. The outer side of the baffle plate body 2 is covered with a galvanized film. Through the arrangement of the baffle plate body 2, the first dispersion hole 5, the first baffle 6, the second baffle 7, the second dispersion hole 8, the hydraulic damper 13, and the lifting frame 15, the device can generate waves by shaking the fuel in the fuel tank body 1 during use. When the fuel wave comes into contact with the baffle plate body 2, it will pass through several second dispersion holes 8 and first dispersion holes 5, thereby dispersing the fuel wave and reducing the energy of the fuel impacting the inner wall of the fuel tank body 1, thus reducing noise generation. The hydraulic damper 13 enables the baffle plate body 2 to sway up and down after being impacted by the fuel wave, and reduces the swaying amplitude and impact force of the baffle plate during swaying, thereby further reducing the impact force of the fuel wave on the baffle plate body 2 and the inner wall of the fuel tank body 1. This solves the problem that the fuel wave formed inside the fuel tank during vehicle operation will generate noise, interfere with the driver's auditory environment, affect the driver's attention, and pose a potential safety hazard.
[0018] The implementation principle of this application embodiment is as follows: In use, the baffle plate body 2 is placed inside the fuel tank body 1. After placement, the threaded rod 16 is passed through the lifting frame 15 and positioned inside the lifting frame 15. Then, the position of the baffle plate body 2 is adjusted so that the threaded rod 16 enters the mounting hole 17 inside the mounting plate 9 at the bottom of the baffle plate body 2. Then, the first positioning nut 18 is threaded onto the outside of the threaded rod 16. After threading, the position of the first positioning nut 18 is adjusted so that the first positioning nut 18 contacts the mounting plate 9. Then, the second positioning nut 19 is threaded onto the end of the threaded rod 16 away from the first positioning nut 18. After threaded connection, adjust the position of the second positioning nut 19 to move it and make it contact the side of the lifting frame 15, thereby completing the limiting of the mounting plate 9. Then, install the remaining threaded rods 16 and mounting plate 9 in the same way as described above. After installation, it can be used. Before use, place the top cover 3 on the top of the fuel tank body 1 and fix the fuel tank body 1 and the top cover 3 by welding. After connection, the fuel tank body 1 is located inside the car. Then, connect the fuel passage of the car to the fuel tank body 1. When the car is moving, the fuel tank body 1 shakes with the car. After the fuel tank body 1 shakes, the fuel inside the fuel tank body 1 is released. The fuel sloshes and forms fuel waves, which then impact the inner wall of the fuel tank body 1, generating noise. When the fuel waves first impact the inner wall of the fuel tank body 1, they first contact the baffle plate body 2. Upon contact, the baffle plate body 2 initially reduces the impact force of the fuel waves. When the impact force of the fuel waves is too large, it pushes the baffle plate body 2 upwards. The upward movement of the baffle plate body 2 causes the mounting plate 9 to push the threaded rod 16, which in turn pushes the lifting frame 15. The upward movement of the lifting frame 15 causes the output shaft of the hydraulic damper 13 to retract, thus reducing the impact force of the baffle plate body 2 and completing the initial noise reduction. When waves impact the baffle plate body 2, some fuel passes through the first dispersion hole 5, the first baffle 6, the second baffle 7, and the second dispersion hole 8. The first dispersion hole 5 and the second dispersion hole 8 then disperse the fuel waves, reducing the impact force of the dispersed fuel waves. This further reduces the impact force of the fuel waves on the baffle plate body 2 and the inner wall of the fuel tank body 1. The first baffle 6 and the second baffle 7 protect the edges of the first dispersion hole 6 and the edges of the baffle plate body 2, reducing the impact force of the fuel waves on the baffle plate body 2, increasing the lifespan of the baffle plate body 2, and reducing the noise generated by the fuel waves impacting the inner wall of the fuel tank body 1.
