As shown in fig. 1-2, a battery compartment assembly 100 according to one embodiment of the present invention includes a plurality of battery compartments 1 and a plurality of drop compartments 2.

The battery bins 1 are distributed in sequence, the inner cavities of two adjacent battery bins 1 are spaced, and the battery bins 1 are used for installing the battery packs 11, so that the battery bins 1 not only can store the battery packs 11, but also can space the battery packs 11 from other battery packs 11. As shown in fig. 1, the battery bins 1 may be distributed at intervals along a horizontal direction, and in actual use, the battery packs 11 may be installed in one or more of the battery bins, so as to store a large number of battery packs 11.

Each battery compartment 1 is provided with a fire extinguishing mechanism 3, and the fire extinguishing mechanism 3 can directly act on the inner cavity of the battery compartment 1, such as spraying fire extinguishing agent towards the inside of the battery compartment 1, so as to extinguish fire in the battery compartment 1. In other words, when the battery pack 11 in the battery compartment 1 has a thermal runaway fire, the fire extinguishing agent can be sprayed into the battery compartment 1 through the fire extinguishing mechanism 3, so that the fire of the battery pack 11 can be relieved or eliminated. It should be noted that, each battery compartment 1 may correspond to one fire extinguishing mechanism 3 separately, so that the fire extinguishing mechanisms 3 between the battery compartments 1 do not interfere, thereby improving fire extinguishing efficiency and ensuring safety of the battery pack 11.

And, a plurality of the bins 2 that fall distribute in the bottom of a plurality of battery compartment 1 in one-to-one correspondence, as shown in fig. 1, a plurality of battery compartments 1 distribute in proper order along the horizontal direction, and simultaneously, a plurality of the bins 2 that fall distribute in proper order along the horizontal direction, that is, the quantity of the bins 2 that fall can be set to the same as the quantity of the battery compartments 1, and each bin 2 that falls can just set up along the vertical direction with the corresponding battery compartment 1.

And a falling mechanism 34 is arranged in each battery compartment 1, and the falling mechanism 34 is used for controlling the battery pack 11 in the battery compartment 1 to fall into the corresponding falling compartment 2, in other words, the bottom of the battery compartment 1 can be selectively communicated with the top of the falling compartment 2. Therefore, when the battery pack 11 in the battery compartment 1 is out of fire thermal runaway, the bottom of the battery compartment 1 and the top of the falling compartment 2 can be switched into a communication state through the falling mechanism 34, so that the battery pack 11 in the battery compartment 1 automatically falls into the falling compartment 2 under the action of gravity, the battery pack 11 is prevented from triggering the adjacent battery pack 11 in the battery compartment 1 to be out of fire thermal runaway, the condition that the battery pack 11 with a large area is ignited is well avoided, and the safety of the battery pack 11 is improved.

According to the battery compartment assembly 100 provided by the embodiment of the invention, the falling compartments 2 corresponding to the battery compartments 1 one by one are arranged, and the falling mechanism 34 is matched, so that the falling and replacement of the single battery pack 11 can be realized, the replacement cost is reduced, the fire extinguishing effect of the single battery pack 11 can be realized by utilizing the fire extinguishing mechanism 3, the problem that the single battery pack 11 ignites the large-area battery pack 11 when the single battery pack 11 is on fire is well avoided, and the storage safety of the battery pack 11 is improved.

In some embodiments, an open opening is formed at the bottom of the battery compartment 1, where it is noted that the top of the falling compartment 2 is in an open state, and the bottom of the battery compartment 1 may be communicated with the falling compartment 2 through the open opening, so that the battery pack 11 in the battery compartment 1 may automatically fall into the falling compartment 2 by using gravity.

Wherein, the falling mechanism 34 includes a fixing plate 341 and a fixing member, the fixing plate 341 is located at the open opening and is used for supporting the battery pack 11, the fixing member is mounted to the battery compartment 1, and the fixing member is used for holding the fixing plate 341 at the open opening or controlling the fixing plate 341 to fall from the open opening. That is, the fixing member may selectively apply a force to the fixing plate 341, the fixing plate 341 may be maintained at the opening by the force of the fixing member to support and fix the battery pack 11, and when the fixing member removes the force to the fixing plate 341, the fixing plate 341 is separated from the opening to lose the supporting effect on the battery pack 11, so that the battery pack 11 is automatically adjusted into the falling bin 2 by gravity to replace the battery pack 11 and isolate from other battery packs 11.

Illustratively, as shown in fig. 2, the fixed plate 341 is positioned at the right middle in the open mouth, and the fixing members are positioned at both sides of the fixed plate 341, and the force applied by the fixed plate 341 toward the fixed plate 341 can overcome the gravity of the fixed plate 341 and the battery pack 11. It should be noted that, the fixing plate 341 may be reused, that is, after the fixing member removes the acting force on the fixing plate 341, the fixing plate 341 falls, and after the worker replaces the battery 11 again, the fixing member may be reused to keep the fixing plate 341 at the opening, so as to realize the reuse of the fixing plate 341, and reduce the setting cost.

In some embodiments, the fixing member includes two electromagnets 342, and the two electromagnets 342 are located at both sides of the opening, respectively, and the fixing plate 341 is adapted to be held between the two electromagnets 342 by suction, so that the two electromagnets 342 can simultaneously act on the fixing plate 341 to enable the fixing plate 341 to be stably held at the opening. Thereby, compared with the adsorption of the fixed plate 341 by the single electromagnet 342, the acting force of the two electromagnets 342 on both sides of the fixed plate 341 is more uniform, thereby facilitating the horizontal holding of the fixed plate 341 at the open hole, and avoiding the unstable placement of the battery pack 11 caused by the inclination of the fixed plate 341.

Wherein, the state of the fixed plate 341 is controlled by the electromagnet 342, and a control module can be set to control the energizing state of the electromagnet 342, for example, when in actual use, the control module controls the electromagnet 342 to energize to generate magnetic attraction to realize the fixed holding of the fixed plate 341, and when the battery 11 fires, the control module controls the electromagnet 342 to deenergize to remove the holding force of the fixed plate 341, thereby realizing the automatic falling of the battery 11.

In practical design, the spraying hole can be formed into a flaring shape, so that the fire extinguishing agent at the spraying hole is scattered and sprayed on the top of the battery pack 11 in a diffusion shape, the fire extinguishing agent is covered in a larger range, and the effectiveness of fire extinguishing is ensured.

It should be noted that, as shown in fig. 2, after the battery pack 11 is installed in the battery compartment 1, a certain height difference is maintained between the top of the battery pack 11 and the spraying hole, so that the fire extinguishing agent at the spraying hole has a certain spraying distance, which is beneficial to scattering the fire extinguishing agent and increases the spraying range to the battery pack 11.
