Description

Technical Field

[0001] This utility model belongs to the field of marine battery module technology, and in particular relates to a modular stacked marine battery pack structure. Background Technology

[0002] Marine batteries are widely used in ship propulsion and equipment power supply applications. They consist of multiple battery modules and combiner boxes, providing a stable and efficient power supply during ship navigation. Battery modules can be used independently or connected and fixed together as needed. During ship operation, due to complex conditions such as turbulence and vibration, the design of marine battery boxes must prioritize structural stability.

[0003] Conventional marine battery packs typically use external frames for series and parallel connections, resulting in a cluttered and unsightly appearance that negatively impacts product aesthetics. On-site system assembly is also complex, time-consuming, and labor-intensive, requiring additional stacking frames. Therefore, achieving rapid assembly or disassembly of battery modules while meeting structural stability requirements is a pressing technical challenge. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a modular stacked marine battery pack structure that can quickly assemble or disassemble battery modules without the need for an additional frame.

[0005] To achieve the above objectives, this utility model employs the following technical solution: a modular stackable marine battery pack structure, comprising several stackable boxes, each box including a frame with a top opening and a battery module located within the frame, wherein the top plane of the battery module is higher than the upper edge of the frame, forming a protrusion, and the frame including a bottom plate, wherein the plane of the bottom plate is higher than the lower edge of the frame, forming a recess, and when the boxes are stacked, the recess of the upper box and the protrusion of the lower box are in contact with each other.

[0006] Optionally, the frame includes at least four side plates, which are connected end to end to form a closed loop.

[0007] Optionally, one of the side panels is provided with several interfaces.

[0008] Optionally, the side plates located on both sides of the interface are provided with a first cavity, a second cavity and a third cavity. A nut sleeve is installed on the top of the first cavity, a connecting hole is provided at the bottom of the second cavity, and connecting holes are provided at both the top and bottom of the third cavity. The connecting holes are used to insert a threaded rod.

[0009] Optionally, the threaded rod in the upper housing passes through the second and third cavities in sequence and is threadedly connected to the nut in the lower housing to fix the upper and lower housings.

[0010] Optionally, a plurality of windows are provided on one side of the second cavity, and the windows are located on one side of the threaded rod.

[0011] Optionally, handles are installed on the side plates located on both sides of the interface.

[0012] Optionally, each of the side panels has an inner wall with a mounting plate, and the mounting plate has several mounting holes. The battery module is connected to the mounting plate by bolts.

[0013] Optionally, the enclosure includes a junction box and several battery boxes, with the junction box located on the top layer.

[0014] Optionally, the junction box includes a flat opening located on one side of the frame, and the plane of the flat opening is flush with the bottom of the base plate.

[0015] Compared with the prior art, the beneficial effects achieved by this utility model are as follows: 1. By setting a protrusion at the top cover of the battery module and a recess at the bottom of the frame, the recess of the upper box and the protrusion of the lower box cooperate with each other, and the boxes are quickly stacked to realize the series and parallel connection of the battery PACK. Then, several threaded rods are used to fix and connect the corresponding side plates of the upper and lower boxes, thereby improving the structural stability.

[0016] 2. By placing the protrusions and recesses on the inside of the frame, the frames around the upper and lower boxes fit tightly when the boxes are stacked. The entire battery stacked in series and parallel is relatively simple and beautiful. The system is quick and easy to assemble, and its aesthetics and grade are significantly improved.
