Description

Technical Field

[0001] The utility model relates to the technical field of battery steel structures, and particularly relates to an anti - shedding steel structure for a hydrogen battery chamber of a hydrogen - energy locomotive. Background Technique

[0002] With the global emphasis on clean energy and sustainable development, hydrogen energy, as an efficient and clean form of energy, is increasingly widely used in the transportation field. As an important part of it, the hydrogen - energy locomotive's power source - the hydrogen - battery system is the key to ensuring the normal operation of the locomotive. However, due to the high energy density and relatively large self - weight of hydrogen batteries, during the locomotive's operation, especially when encountering complex road conditions or emergency braking, etc., the battery chamber may be strongly vibrated and bumped.

[0003] Conventional battery chamber designs often use ordinary steel or aluminum alloy materials to construct. Although these materials have a certain strength and stiffness, under the long - term bearing of the battery's self - weight and external impacts, they are prone to fatigue damage, resulting in the loosening or even shedding of the connection between the battery chamber and the vehicle body. Once the battery chamber falls off, it will not only cause direct damage to the battery, but may also trigger serious safety accidents such as short - circuits and fires, posing a major threat to the safety of locomotive operation.

[0004] In order to solve the above problems, the outer side of the battery chamber can be wrapped and protected, and it can be strengthened to enhance its anti - vibration and anti - bumping capabilities, ensuring the stability and safety of the battery chamber during long - term use. For this reason, we propose an anti - shedding steel structure for a hydrogen - energy locomotive hydrogen battery chamber. Content of the Utility Model

[0016] (III) Beneficial effects

[0017] Compared with the prior art, the utility model provides an anti-detachment steel structure for a hydrogen battery chamber of a hydrogen energy locomotive, which has the following beneficial effects:

[0018] 1. For the anti-detachment steel structure of the hydrogen battery chamber of the hydrogen energy locomotive, through the setting of the fixing component, the connection stability between the battery chamber and the chassis is significantly enhanced. In particular, the fitting surface between the fixing groove plate and the closing plate is increased with the fitting plate, effectively increasing the contact area, improving the firmness and seismic resistance of the connection.

[0020] 3. The anti-detachment steel structure of the hydrogen battery compartment of this hydrogen-powered locomotive provides an all-round protective barrier for the battery compartment through the setting of the protection component. The connecting rod, as a connecting and load-bearing structure, is firmly installed on the top of the connecting seat, while the inclined side wall slant plate plays a role in guiding the collision force and dispersing the impact energy, effectively reducing the direct impact of the collision on the battery compartment. This design not only reduces the impact on the battery pack caused by the collision, but also improves the overall protection ability of the battery compartment, ensuring the safety and reliability of the hydrogen battery under complex working conditions.

On the back side of the fixing groove plate 5, a mounting plate 7 for installation is also fixedly installed. Through the setting of the fixing component, the connection stability between the battery chamber 4 and the chassis 1 is significantly enhanced. Especially, the fitting surface between the fixing groove plate 5 and the closing plate 3 is increased with the fitting plate 6, effectively increasing the contact area, improving the firmness and seismic resistance of the connection.
