Description

Technical Field

[0001] The utility model relates to the technical field of energy storage electrical cabinets, in particular to a door lock mechanism of an energy storage cabinet. Background Art

[0002] The traditional door lock mechanism on ordinary cabinets uses a central lock and upper and lower rods inserted into the door frame to achieve a seal. For cabinets with low height and no sealing requirements, the traditional door lock mechanism can meet the needs.

[0003] The energy storage cabinet consists of two compartments: the battery compartment and the electrical compartment. Because the energy storage batteries require a constant temperature during operation, the battery compartment is equipped with air conditioning or a chiller for temperature control. The battery compartment requires a relatively enclosed space for insulation. The entire energy storage cabinet is typically used outdoors, exposed to the sun and rain, and the cabinet doors must be rainproof. Furthermore, the electrical and battery components of the energy storage cabinet require regular annual maintenance, requiring frequent door openings. Furthermore, the energy storage cabinet must maintain a certain floor space, and the stacked energy storage batteries and electrical components must be greater than two meters high. To ensure a sealed energy storage system, multiple locking points are required, and operation must be simple, with one lock connecting multiple locking points.

[0004] Therefore, energy storage cabinets require high sealing requirements, and traditional three-point locks are insufficient. Furthermore, a rod is typically attached to the door lock, which slides into a slot in the cabinet to prevent the door from opening. However, due to the height of electrical cabinets, the rod is long, making it difficult to align the rod with the hole. Enlarging the hole to facilitate alignment also results in poor sealing after the door is closed, shortening the lifespan of the door lock assembly. Utility Model Content

[0005] The purpose of the utility model is to provide an energy storage cabinet door lock mechanism to solve the problems that the existing energy storage cabinet door cannot be fastened at multiple points with one lock, the door lock is inconvenient to operate and the sealing effect is poor.
