Description

Technical Field

[0001] This utility model belongs to the field of battery technology, and in particular relates to an anti-vibration connection structure for fixing the rear of a battery module. Background Technology

[0002] Currently, battery cabinets are typically shipped empty to customer sites, with modules and main control boxes shipped separately and assembled into the cabinet upon arrival. To achieve full cabinet transportation and meet transportation testing requirements, the modules are reinforced.

[0003] Since the entire container is shipped to the customer's site, the front and rear fixed modules need to be removed to meet the needs of later maintenance. This requires removing the rear door first and then removing the rear fixing, which is quite troublesome. Some door panels have large installation gaps, making them difficult to disassemble and reassemble. If the installer misses this process of removing the rear fixing, it will affect later maintenance. Summary of the Invention

[0004] This utility model provides a shock-resistant connection structure for fixing the rear of a battery module, aiming to solve the shortcomings of existing transport battery cabinets, such as requiring the rear door panel to be removed before removing the rear fixing after delivery, large installation gaps in the rear door panel making disassembly and assembly difficult, and installation personnel forgetting to remove the rear fixing, thus affecting later maintenance. This utility model, through ingenious design, directly fixes the battery module and the rear door panel together, facilitating on-site installation and maintenance for customers.

[0005] The present invention is implemented as follows:

[0006] An anti-vibration connection structure for fixing the rear of a battery module includes a battery module, a module fixing unit, a rear door panel, and a rubber plug.

[0007] The battery module is fixedly connected to the rear door panel through the module fixing unit. The rear door panel is provided with a rubber plug hole, and the rubber plug is matched with the module fixing unit through the rubber plug hole.
