Description

Technical Field

[0001] This utility model relates to the field of vibration damper technology, and in particular to a corrosion-resistant vibration damper specifically designed for hydrogen fuel cell vehicles. Background Technology

[0002] Hydrogen fuel cell vehicles experience severe vibrations during operation, which can easily lead to loosening or corrosion and leakage of hydrogen fuel tank connections. Traditional shock absorbers lack protective designs against the corrosive environment of hydrogen, and the fuel tank fixing methods are limited (such as welding or bolted connections), making them difficult to adapt to various tank sizes and causing inconvenience for maintenance and replacement. Furthermore, insufficient absorption of combined vertical and horizontal vibrations poses safety hazards. Utility Model Content

[0003] The main purpose of this invention is to provide a corrosion-resistant vibration damper specifically for hydrogen fuel cell vehicles, which can effectively solve the problems in the background art.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] A corrosion-resistant vibration damper for hydrogen fuel cell vehicles includes a corrosion-resistant base shell. An "L"-shaped plate is rotatably mounted between the two side walls of the corrosion-resistant base shell. A corrosion-resistant housing shell is fixedly mounted on one side of the "L"-shaped plate. Several fixed base plates are fixedly mounted on one side of the inner surface of the corrosion-resistant housing shell. Each of the fixed base plates is provided with a spiral buckle, and a hydrogen fuel tank is fixedly mounted on it through the spiral buckle. Several first springs are fixedly mounted between the bottom surface of the bottom plate of the corrosion-resistant housing shell and the corrosion-resistant base shell. Several second springs are fixedly mounted between the bottom plate of the "L"-shaped plate and the corrosion-resistant base shell. A second rubber damping block and a first rubber damping block are mounted on the corrosion-resistant base shell. The second rubber damping block overlaps with the top surface of the "L"-shaped plate, and the first rubber damping block overlaps with the bottom surface of the corrosion-resistant housing shell.

[0006] Preferably, the top and bottom of the fixed base plate are both fixedly installed with arc-shaped clamps, and the two arc-shaped clamps are adapted to the size of the hydrogen fuel tank.

[0007] Preferably, a handle is fixedly installed at one end of the hydrogen fuel tank.

[0008] Preferably, two rubber blocks are fixedly installed on the outer surfaces of both sides of the anti-corrosion bottom shell, and two support plates are fixedly installed between the top surfaces of the four rubber blocks, with several mounting holes on each of the two support plates.

[0009] Preferably, an anti-corrosion flip cover is hinged to the open end of the anti-corrosion housing, a latch is installed between the anti-corrosion flip cover and the anti-corrosion housing, and a locking mechanism is installed between the fixed base plate and the hydrogen fuel tank.

[0010] Preferably, the hydrogen fuel tank is detachably fixed to the fixing base plate by the spiral buckle, and the size of the hydrogen fuel tank is adapted to the internal space of the corrosion-resistant housing.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] 1. The anti-corrosion bottom shell and the anti-corrosion housing shell form a sealed cavity, isolating the tank from road salt spray and chemical corrosive media; the anti-corrosion flip cover further seals the shell opening through a locking mechanism, forming a triple protective layer. This design significantly reduces the risk of surface corrosion of the hydrogen fuel tank, extends the tank's lifespan, and adapts to the highly corrosive environment of fuel cell vehicles.

[0013] 2. The first spring and the first rubber damping block work together to absorb vertical vibrations and prevent the hydrogen fuel tank from being impacted vertically; the rotation of the "L"-shaped plate links the second spring and the second rubber damping block to decompose the lateral vibration energy. The multi-stage buffer structure reduces a large amount of peak impact force and prevents pipeline loosening and leakage.

[0014] 3. The spiral buckle, combined with the arc-shaped clamp, enables radial locking and dimensional self-adaptation of the hydrogen fuel tank. Disassembly only requires unlocking the buckle; the handle provides a manual operating fulcrum for quick tank replacement. The locking mechanism prevents loosening during driving, balancing maintenance efficiency and safety.

[0015] 4. The rubber blocks between the support plate and the frame form a secondary vibration isolation layer, absorbing high-frequency vibration waves; when the mounting holes are fixed to the frame, the rubber elastomer attenuates some of the high-frequency noise, reduces the resonance energy transmitted to the anti-corrosion bottom shell, and improves driving comfort.

[0016] 5. The dimensions of the hydrogen fuel tank are precisely matched with the inner cavity of the corrosion-resistant housing to eliminate vibration gaps between the tank and the cavity wall; the stiffness parameters of the springs and rubber damping blocks are optimized for the resonant frequency of the hydrogen tank to suppress structural fatigue fracture caused by low-frequency resonance and ensure the safety of high-pressure hydrogen storage.

[0022] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0023] like Figure 1-4 As shown, a corrosion-resistant vibration damper for hydrogen fuel cell vehicles includes a corrosion-resistant base shell 1. An "L"-shaped plate 2 is rotatably installed between the two side walls of the corrosion-resistant base shell 1. A corrosion-resistant housing shell 6 is fixedly installed on one side of the "L"-shaped plate 2. Several fixed base plates 15 are fixedly installed on one side of the inner surface of the corrosion-resistant housing shell 6. Each of the several fixed base plates 15 is provided with a spiral buckle, and a hydrogen fuel tank 8 is fixedly installed through the spiral buckle. Several first springs 11 are fixedly installed between the bottom surface of the bottom plate of the corrosion-resistant housing shell 6 and the corrosion-resistant base shell 1. Several second springs 14 are fixedly installed between the bottom plate of the "L"-shaped plate 2 and the corrosion-resistant base shell 1. A second rubber damping block 13 and a first rubber damping block 10 are installed on the corrosion-resistant base shell 1. The second rubber damping block 13 overlaps with the top surface of the "L"-shaped plate 2, and the first rubber damping block 10 overlaps with the bottom surface of the corrosion-resistant housing shell 6.

[0024] In this embodiment, arc-shaped clamps 12 are fixedly installed on the top and bottom of the fixed base plate 15. The two arc-shaped clamps 12 are adapted to the size of the hydrogen fuel tank 8. A handle 9 is fixedly installed on one end of the hydrogen fuel tank 8. An anti-corrosion flip cover 7 is hinged to the open end of the anti-corrosion housing 6. A latch is installed between the anti-corrosion flip cover 7 and the anti-corrosion housing 6. A locking mechanism is installed between the fixed base plate 15 and the hydrogen fuel tank 8.

[0025] Specifically, the arc-shaped clamps 12 at the top and bottom of the fixed base plate 15 provide radial auxiliary fixation for the hydrogen fuel tank 8. Their design, adapted to the tank size, prevents tank swaying during transportation, enhancing stability. The handle 9 at the end of the hydrogen fuel tank 8 provides a manual operating fulcrum, facilitating quick assembly and disassembly of the tank and reducing maintenance difficulty. The corrosion-resistant flip cover 7, through hinges and latches, seals the corrosion-resistant housing 6, blocking external corrosive media; the locking mechanism, such as a pin or slot, forms a double lock with the spiral buckle, preventing the hydrogen fuel tank 8 from loosening during vibration.

[0026] In this embodiment, two rubber blocks 5 are fixedly installed on the outer surfaces of both sides of the anti-corrosion bottom shell 1, and two support plates 3 are fixedly installed between the top surfaces of the four rubber blocks 5. Several mounting holes 4 are opened on the two support plates 3. The hydrogen fuel tank 8 is detachably fixed to the fixed base plate 15 by a spiral buckle, and the size of the hydrogen fuel tank 8 is adapted to the internal space of the anti-corrosion housing shell 6.

[0027] Specifically, the rubber block 5 on the side wall of the anti-corrosion base shell 1 and the support plate 3 form a secondary vibration isolation layer. When connected to the vehicle frame through the mounting hole 4, the rubber block 5 absorbs high-frequency vibrations, reducing the impact energy transmitted to the anti-corrosion base shell 1. The hydrogen fuel tank 8 and the fixed base plate 15 are connected by a detachable spiral buckle, and the tank size matches the internal space of the anti-corrosion housing 6 to avoid tank resonance due to gaps and improve vibration reduction efficiency.

[0028] Working principle: Vibration transmission path: frame vibration, support plate 3, rubber block 5, anti-corrosion bottom shell 1.

[0029] Vibration reduction process: Vertical direction: When the anti-corrosion housing 6 is pressed down, the first spring 11 is compressed and the first rubber damping block 10 deforms and consumes energy; Horizontal direction: Vibration pushes the "L"-shaped plate 2 to rotate around the axis, the second spring 14 is stretched / compressed, and the second rubber damping block 13 suppresses rebound.

[0030] Tank fixing: The hydrogen fuel tank 8 is locked to the fixed base plate 15 by a spiral buckle, and the arc-shaped clamp 12 restricts radial displacement; the locking mechanism prevents the spiral buckle from loosening.

[0031] The circuits, electronic components, and control modules involved are all existing technologies, which can be fully implemented by those skilled in the art, and need not be elaborated upon. The content protected by this utility model does not involve any improvement to the software and methods.

[0032] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
