[0001] The utility model relates to the technical field of energy storage battery packs, in particular to an anti-collision mechanism for an ultra-large battery pack. Background Art

[0002] In the energy storage system, the function of the battery is to store electrical energy. Since the capacity of a single battery is limited, the system usually combines multiple batteries in series and parallel to achieve the designed voltage level and capacity requirements, so it is also called an energy storage battery pack.

[0003] There are many types of such energy storage battery packs on the market today, which can basically meet people's needs, but there are still some problems: if traditional energy storage battery packs of this type are not protected during use, they may explode when they are hit, so they need to be improved. To this end, we propose an anti-collision mechanism for super-large battery packs. Utility Model Content

[0004] In view of the problems in the prior art, the utility model provides an anti-collision mechanism for an ultra-large battery pack.

[0005] The technical solution adopted by the utility model to solve the technical problem is an anti-collision mechanism for a super-large battery pack, comprising a protective shell, two sides of the bottom end of the protective shell are respectively provided with limited sliding grooves, the interior of the limited sliding grooves is slidably connected with sliding wheels, and the sliding wheels are multiple and respectively fixedly installed at the four corners of the bottom end of the fixed base, the top of the fixed base is fixedly installed with a connecting rod, and the top of the connecting rod is plugged and installed with an extended protective plate;

[0006] The fixed base and one side surface of the extended protective plate are fixedly connected to a limiting slot, a positioning plug is inserted into the interior of the limiting slot, and the positioning plug is fixedly installed on the side wall of the battery frame plate. A battery pack is installed inside the battery frame plate, and the battery pack is placed on the top of the protective rubber, and the protective rubber is respectively fixedly installed on the surfaces of the top and bottom ends of the extended protective plate and the top surface of the fixed base.

[0007] By adopting the above technical solution, the battery pack can be conveniently removed or fixed in a protective casing with a certain shock-resistant buffer material by sliding out, avoiding the need to disassemble the protective casing to remove the battery pack when the battery pack is inspected or maintained, thereby improving maintenance efficiency. The extended protective plate fixed to the surface of the fixed base is stacked to separate each battery panel, thereby avoiding the hidden danger of battery explosion or spontaneous combustion caused by squeezing, colliding and expanding due to shaking of the battery panel.

[0008] Specifically, the four corners of the top end of each of the extended protection plates are fixedly connected with connecting rods, and the four corners of the bottom end of the extended protection plates are provided with plug-in slots that match the connecting rods.

[0010] Specifically, the side walls of the fixed base and the extended protection plate are both provided with cables and electrical plug-in interfaces.

[0011] By adopting the above technical solution, the series or parallel connection of the fixed base and the extended protection plate is achieved through cables according to the electricity consumption standard.

[0012] Specifically, the fixed base is connected to the protective shell via a cable to achieve charging and discharging.

[0013] By adopting the above technical solution, the battery connected to the fixed base is connected to an external electrical device or a power source through a cable from the protective shell.

[0014] Specifically, the side wall of the protective shell is provided with a heat dissipation opening for air circulation.

[0015] By adopting the above technical solution, the heat dissipation port is used to prevent heat from being accumulated in the protective shell, which would cause the battery working environment to overheat.

[0016] Compared with the prior art, the utility model has the following beneficial effects:

[0017] The technical solution of the present application uses a protective shell, a limiting slide groove, a fixed base, a sliding wheel, a connecting rod, an extended protective plate, a battery pack and a protective rubber structural design to separate the battery packs through a protective rubber partition made of explosion-proof insulating material and slidably connect the battery packs in the protective shell to prevent external impacts from causing collisions between battery packs, resulting in battery bulging, explosion or spontaneous combustion.
