Description

Technical Field

[0001] This utility model relates to the field of new energy battery pack technology, specifically to an improved structure for installing liquid cooling plates in new energy storage battery packs. Background Technology

[0002] New energy storage cabinets and battery packs are important components in the new energy field, possessing functions such as energy storage, energy management, and protection. A new energy storage cabinet mainly consists of a battery pack, an energy management system (EMS), a battery management system (BMS), charging equipment, and an inverter. It is responsible for storing and releasing energy, optimizing energy dispatch, monitoring and protecting batteries, and converting electrical energy. The battery pack is one of the core components of the storage cabinet, including battery modules, a casing, and a liquid cooling plate.

[0003] The aforementioned devices lack a structure for preventing battery packs from being bumped and inserted into the energy storage cabinet. As a result, when inserting existing battery packs into the energy storage cabinet, the bottom guide rail of the battery pack's liquid cooling plate is usually connected to the guide rail inside the energy storage cabinet. However, due to the need to ensure stability, the insertion distance between the guide rails of the battery cabinet and the battery pack is relatively short, making it easy for collisions to occur during the insertion process, which can damage the battery pack or the battery cabinet. Based on the shortcomings of existing technology, this utility model designs an improved structure for the installation of liquid cooling plates in new energy storage battery packs. Utility Model Content

[0006] The mounting mechanism includes a bottom rail, a bevel plug, and a bottom rail hole. The bottom rail is fixedly connected to the lower surface of the liquid cooling plate body, the bevel plug is fixedly connected to the inner end of the bottom rail, and the bottom rail hole is opened at the outer end of the bottom rail.

[0008] As a preferred embodiment of this utility model, a connecting panel is fixedly connected to the front of the battery cover, an upper fixing strip is fixedly connected to the bottom of the battery cover, and a handle is fixedly connected to the upper surface of the upper fixing strip.

[0009] As a preferred embodiment of this utility model, the front end of the fixed guide rail is provided with a guide rail hole, a fixing strip is fixedly connected to the upper surface of the front end of the fixed guide rail, a first nut is connected through the fixing strip, and a second nut is connected through the fixing strip.

[0010] As a preferred technical solution of this utility model, a side inspection plate is fixedly connected to the side of the energy storage cabinet body, a main cabinet door is rotatably connected to the front of the energy storage cabinet body, a secondary cabinet door is rotatably connected to the front of the energy storage cabinet body, and the main cabinet door is rotatably connected to the opening of the battery compartment.

[0013] As a preferred embodiment of this utility model, the upper fixing strip is fixedly connected to the upper surface of the lower fixing strip.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] This invention improves the structure for installing liquid cooling plates in new energy storage battery packs. By using a lifting device connected to a handle, the battery cover, liquid cooling plate body, and battery cells are raised. Once the liquid cooling plate body is raised to the same height as the corresponding fixed guide rail, movement stops. The battery cover and liquid cooling plate body are then slowly moved to align the insertion bottom rail with the fixed guide rail. At this point, the battery cover, liquid cooling plate body, battery cells, and insertion bottom rail are pushed inwards. If a slight angular deviation occurs when the insertion bottom rail is inserted into the inside of the fixed guide rail, the inclined surface of the angled plug can be inserted into the inside of the fixed guide rail in advance to guide the insertion direction of the insertion bottom rail, while simultaneously preventing the liquid cooling plate body, battery cover, and battery cells from colliding with the energy storage cabinet body. This device facilitates the rapid installation of the liquid cooling plate body, battery cover, and battery cells into the energy storage cabinet. Attached Figure Description

[0032] Working principle: When a structure for improving the installation of liquid cooling plates in a new energy storage battery pack is used, in the initial state, the battery compartment 102 is first opened inside the main body 1 of the energy storage cabinet, and the fixed guide rail 2 is set on the inner wall of the battery compartment 102 to fix multiple sets of liquid cooling plate bodies 401, battery cover 3 and battery cells. The tail end of the insertion bottom rail 402 fixedly connected to the bottom of the liquid cooling plate body 401 is fixedly connected with a bevel plug 403 to facilitate the quick docking of the auxiliary insertion bottom rail 402 with the fixed guide rail 2 to insert the liquid cooling plate body 401 and battery cover 3.
