[0002] A battery is a device that can convert chemical energy into electrical energy and store it. It consists of positive and negative plates and an electrolyte. It stores electrical energy through chemical reactions and releases it when needed. Batteries are widely used in various fields, such as portable electronic devices, automobiles, backup power systems, etc. They have different types, including lead-acid batteries, nickel-cadmium batteries, lithium-ion batteries, etc., each with its own characteristics and applicable scenarios. Batteries play an important role in providing portable energy, balancing energy supply and demand, and coping with power outages.

[0003] An electric locomotive is a railway locomotive that uses electricity as its power source. It drives the wheels to rotate through an electric motor. It is usually powered by wires or a third rail, but can also be powered by batteries. Electric locomotives have the advantages of zero emissions, low noise, and high efficiency. They are widely used in urban rail transit, long-distance passenger and freight transportation, and other fields. Their design usually includes components such as the body, motor, and inverter to achieve high-speed operation and heavy-load traction. Electric locomotives play an important role in railway transportation and have promoted the modernization and environmental protection of railway transportation.

[0004] In electric locomotives, battery packs are sometimes needed for power supply. The battery packs are connected together through a combined frame. The frame can accommodate multiple battery packs. Since the electric locomotive generates vibrations when running, the battery shells may rupture due to the vibration of the locomotive, resulting in leakage, causing short circuits and locomotive operation accidents. Therefore, a battery combination frame suitable for electric locomotives is proposed to solve the above problems. Utility Model Content
