Description

Technical Field

[0001] This utility model relates to the field of vibration damping pad technology, and in particular to a rubber vibration damping pad for the protection of hydrogen energy batteries. Background Technology

[0002] Rubber damping pads are characterized by both high elasticity and high viscosity. The elasticity of rubber is generated by the change in the conformation of its coiled molecules. The interaction between rubber molecules hinders the movement of molecular chains, thus exhibiting the characteristics of viscous damping. As a result, stress and strain are often in an unbalanced state, giving rubber materials unique viscoelastic properties. Therefore, they have good vibration reduction, sound insulation and buffering performance. Rubber components are widely used to isolate vibration and absorb shock. In the protection of hydrogen fuel cells, rubber damping pads are often required.

[0003] However, existing technologies have some problems: traditional rubber damping pads mostly adopt an integrated solid structure, which is prone to cracking failure due to stress concentration when subjected to local shear stress. Moreover, their damping performance mainly depends on the inherent damping characteristics of rubber materials, and their energy dissipation capacity is limited. In existing designs, due to the lack of optimization of structural deformation paths and the introduction of composite damping mechanisms, the vibration energy absorption efficiency is insufficient, making it difficult to maintain good protection for hydrogen fuel cells. Therefore, we propose a rubber damping pad for the protection of hydrogen fuel cells. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a rubber vibration damping pad for the protection of hydrogen fuel cells.

[0005] The purpose of this utility model is achieved as follows: a rubber vibration damping pad for protecting hydrogen fuel cells includes a first rubber pad and a second rubber pad, which are stacked vertically. Support plates are fixedly installed on the opposite surfaces of both the first and second rubber pads. There are two support plates, which are connected by a vibration damping component. This component enhances the vibration damping and protection effect of the first and second rubber pads on the hydrogen fuel cell. A rubber strip is also provided between the two support plates, and both the first and second rubber pads are fixedly connected to the rubber strip.

[0006] Optionally, the vibration damping assembly includes a damping rod, with both ends of the damping rod fixedly connected to two support plates, and a spring movably sleeved on the outer surface of the damping rod, with both ends of the spring fixedly connected to the two support plates.

[0007] Optionally, the surface of the first rubber pad is provided with through holes, and a pad plate is fixedly installed on the top of the first rubber pad.

[0008] Optionally, the rubber strip has a semi-cylindrical shape and is evenly distributed between the first rubber pad and the second rubber pad.

[0009] Optionally, the rubber strip has a cavity, and the cross-section of the cavity is rhomboid.

[0010] Optionally, the rubber strip has circular holes on both sides, and the circular holes are connected to the cavity.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] This invention, by setting up a support plate, rubber strips, and vibration damping components, allows external vibrations to be transmitted downwards through the hydrogen fuel cell mounted on the first rubber pad. The first and second rubber pads achieve vibration reduction through their own damping effect. At the same time, due to the design of the vibration damping components, the vibration force can be further absorbed and dissipated. Furthermore, the design of the rubber strips allows for the absorption of some vibration force through deformation, thereby improving the absorption rate of vibration energy and enhancing the vibration damping protection effect on the hydrogen fuel cell.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] like Figures 1 to 5 As shown in the figure, the present invention provides a rubber vibration damping pad for protecting hydrogen energy batteries, including a first rubber pad 1 and a second rubber pad 2. The first rubber pad 1 and the second rubber pad 2 are stacked on top of each other. Support plates 3 are fixedly installed on the opposite surfaces of the first rubber pad 1 and the second rubber pad 2. There are two support plates 3. The two support plates 3 are connected by a vibration damping component. The vibration damping component can improve the vibration damping protection effect of the first rubber pad 1 and the second rubber pad 2 on the hydrogen energy battery. A rubber strip 4 is also provided between the two support plates 3. The first rubber pad 1 and the second rubber pad 2 are both fixedly connected to the rubber strip 4.

[0022] Furthermore, the vibration damping component includes a damping rod 7, with both ends of the damping rod 7 fixedly connected to two support plates 3 respectively. A spring 8 is movably sleeved on the outer surface of the damping rod 7, with both ends of the spring 8 fixedly connected to the two support plates 3 respectively.

[0023] Through the design of the damping rod 7 and the spring 8, when the hydrogen battery is placed on the first rubber pad 1, the vibration force will be transmitted to the support plate 3 through the first rubber pad 1 when vibration occurs due to external factors. This allows the damping rod 7 to extend and retract and the spring 8 to deform, thereby further absorbing and dissipating the vibration force and improving the vibration reduction and protection effect of the hydrogen battery.

[0024] Furthermore, a through hole 5 is provided on the surface of the first rubber pad 1, and a pad plate 6 is fixedly installed on the top of the first rubber pad 1.

[0025] The design of the pad 6 allows the hydrogen battery to be installed on the pad 6, creating a gap between the bottom of the hydrogen battery and the first rubber pad 1. This allows the heat from the bottom of the hydrogen battery to dissipate through the through hole 5, thus preventing the first rubber pad 1 from overheating and softening due to prolonged contact with the hydrogen battery, which would reduce its vibration damping capacity.

[0026] Furthermore, the rubber strip 4 has a semi-cylindrical shape and is evenly distributed between the first rubber pad 1 and the second rubber pad 2.

[0027] The semi-cylindrical geometry of the rubber strip 4 can evenly distribute the load along the arc surface, avoid local stress concentration, reduce vibration fatigue of the rubber strip 4, and improve the vibration reduction effect.

[0028] Furthermore, a cavity 9 is provided on the rubber strip 4, and the cross-section of the cavity 9 is rhomboid.

[0029] The design of cavity 9 increases the deformation space and energy absorption effect of rubber strip 4, thereby further improving the vibration reduction effect.

[0030] Furthermore, round holes 10 are provided on both sides of the rubber strip 4, and the round holes 10 are connected to the cavity 9.

[0031] When the rubber strip 4 is deformed under force, it will compress the internal space of the cavity 9, thereby allowing the air inside the cavity 9 to be ejected outward from the round hole 10. This will further expel the heat that flows into the space between the first rubber pad 1 and the second rubber pad 2 from the through hole 5, thereby further improving the heat dissipation effect and ensuring the good vibration damping capacity of the first rubber pad 1 and the second rubber pad 2.

[0032] The above description of the embodiments is only for the purpose of helping to understand the method and core idea of ​​this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made to this utility model without departing from the principle of this utility model, and these improvements and modifications also fall within the protection scope of the claims of this utility model.
